[Emc-users] 5i25 GPIO mapping
Hi Dipping my toes in the FPGA pool, there may be more queries after this. Is the 5i25 supposed to have its GPIO pins mapped in dmesg when hostmot2 / hm2_pci are loaded? (as per http://linuxcnc.org/docs/html/drivers/hostmot2.html#_gpio ) The manual page states that the 5i25 is pre-programmed so does not use firmware files, but is not clear as to whether the printout is a part of the firmware loading process or common to all boards If I run dmesg after starting Lcnc, all I get are a couple of RTAI messages and something like 'hm2_pci: - 5i25 found on IRQ11' but no pinout print for GPIO. I have found the pin I was looking for by trial and error triggering signals on the corresponding 7i76 input but a print out would have been handy, to see which were already mapped to inputs etc regards -- ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

Feel free to borrow away ( I wrote them ) You are right, the routines are basically decrementing / incrementing loops cutting the profile down to finished dimensions. There is no gouging calculation, the profiles that can be cut are limited by tool type, profile and mounting, and ultimately operator common sense. The work very well for me within those limitations but can certainly be improved upon.

Re: [Emc-users] Knee mill conversion - Z axis questions
IMHO if you motorise the knee instead of the quill, you lose all the benefits of the knee elevation for adjusting to workpieces and manually touching off the Z tool, in favour of a very slow and potentially troublesome Z axis which requires all movements to be inverted in a somewhat counter-intuitive way. I agree that whilst possible, motorising the rack and pinion would result in so much slop that it would be next to unusable What is commonly done with manual mill conversions of the turret knee mills is to motorise the quill and leave the knee as manual. The quill is disconnected from the rack and pinion arrangement and large plate clamp is attached to the bottom of the quill This is driven up and down through a ballscrew from a box mounted on the side of the head. The travel is typically quite short (70 - 150 mm), because all major adjustments are done on the knee and quill travel is just used to cut to depth with the standoff between cuts that is required. (same as it was when a manual mill) I have such a mill and it works very well. regards -- Managing the Performance of Cloud-Based Applications Take advantage of what the Cloud has to offer - Avoid Common Pitfalls.

If you are using Linuxcnc to control a CNC machine in the normal manner, but just want to be able to make it run a program from another application, axis-remote could be the simplest method from a system() call There is even an Axis hack and modified axis-remote here http://www.linuxcnc.org/index.php/english/forum/38-general-linuxcnc-questions/26061-automated-change-nc-program-possible#28920 which I wrote to allow a program to be loaded and then run remotely.

Re: [Emc-users] Tool change question
Hi
Have now had a play with this and found how to get it working with 2.5
Comment out the lines
#iniFile = emc.ini(os.environ['INI_FILE_NAME'])
#emc.nmlfile = s.path.join(os.path.dirname(os.environ['INI_FILE_NAME']),
#iniFile.find("EMC", "NML_FILE"))
Change the lines
emcStat = emc.stat();
emcCmd = emc.command()
to
emcStat = emc.stat();emcCmd = emc.command()
Change the lines at about 52-54 with the backslashes in strange places
so that the '\' are end of line continuation markers, as per bash
The module then loads and when toolchange commanded, the dialog appears
and you can jog all axes.
However I found that I had to cycle to and from AXIS using Alt/Tab to
get focus for mouse clicks to work and had to press F2 (machine on/off)
to get out of this state.
Not sure how it was intended to work, but it sort of does

Re: [Emc-users] Tool change question
Hi
I am no python expert, but a couple of things jump out at me.
There has been no reference under [EMC] NML_FILE= in the ini file
since v2.4
Indeed if it is not commented out , EMC will fail to start with multiple
errors.
So the call iniFile.find("EMC", "NML_FILE")) will fail on v2.4 and above.
The error in
File "/usr/lib/python2.6/posixpath.py", line 65
may well have been triggered by the same call, so I would comment line
12 out and see what happens.
Immediately below this call at line 14 is
emcStat = emc.stat();
emcCmd = emc.command()
Note the first call is semi-colon terminated as per C and the second is
not, I don't know if this is right either.
Line 5/6 is
gettext.install("axis", localedir=os.path.join(BASE, "share", "locale"),
unicode=True)
This should all be on one line.
I think line 52/3/4 should read
lab = Tkinter.Message(app, aspect=500, text = _("\
This window is part of the AXIS manual toolchanger. It is safe to close\
or iconify this window, or it will close automatically after a few
seconds."))
rather than as it is currently.
I will try to test this out later and let you know if I succeed

Re: [Emc-users] Next distribution after Ubuntu 10.04 LTS is, no longer supported?
Hi The real problem it seems to me, is one of philosophy rather than what is practically possible. The use of Ubuntu as a carrier vehicle has enabled a lot of people with minimal Linux knowledge to use EMC. As Kirk said, if a better technical solution were used at the expense of usability, that would impact upon the user base unless someone could be bothered to wrapper it for the uninitiated (which is the overwhelming majority). There should be no reason why the user could not have a choice of kernels from the distro at install time, one for SMP another for UP say. That immediately would answer a lot of problems. I personally do not like the later versions of Ubuntu and strip it out and use a light display manager and windowing system, because I hate the bloat and long initialisation time of Gnome and KDE. I have been doing a lot of rtai kernel building recently. Initially to test the effect of different configs on a quad core MB latency and more latterly to try to build a very light Debian based EMC distro, suitable for old machines. In the course of this I found that EMC runs well on a single processor build of both Lenny and Squeeze and will install on both new and old machines. I currently use a Debian Lenny build, not Ubuntu to run EMC. The longer term problem is that EMC has created a dependency upon a version number of Ubuntu to bring the latest version of EMC to the average user. It does not matter how many times users are told that you can run the latest 2.6 RIP on a Ubuntu 8.04 installation. Because it involves the unknown territory of compilation, they are not interested, all they want is another Live CD release that installs everything for them. So cater for them or it is just us geeks! regards -- All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity, and more.

Re: [Emc-users] I feel dumb
Hi You need to say exactly what it is you have, but a lot of the Chinese mini and larger mills sold in the UK and probably elsewhere use a KBLC speed control board to run a 100 - 200v DC motor. The board is actually American and there is good documentation on the net for it. This can be simply reconnected inside to use a £20 speed board to control motor on/off and speed in the place of the potentiometer and switch.

Re: [Emc-users] Limit switch does not work while homing
Hi Not quite following why you would want to press a limit switch during a homing operation, but I am sure that your problems originate in your settings for max velocity and especially max acceleration, which are HUGE, both in [TRAJ] section and the figures for homing. My search velocity on my metric turret knee mill is set at 3.5 and the latch velocity at 1. I jog the axes near to the home positions and then press Ctrl Home Likewise my max velocity is 25 ( equates to 1500mm/min) with acceleration of 9.5, yours are 130 and 200! Not surprised the axis overran. At the same time you have base period and servo period set at 1,000,000. Because you are using servos, this probably matters far less than on my stepper setup, but it is nearly 4 times higher than my base thread. If you scale right down and then work from there I suspect you will resolve it quite simply and tune up to sensible levels The actual error you quote seems to arise in homing where the on / off transition is not clean. I had problems with the error using proximity switches which obviously did not have a clean field collapse point and gave a series of stutters.

Re: [Emc-users] Parallel port card that "just works"?
Hi This was a vexed question for me after I made a pendant and need more IO to work it. None of the Parport IO cards I tried would not work at all, the problem was getting them to work in EPP with pins 2-9 as inputs. I found previous entries from Jon, Kirk and others on this subject. By repeated experiment; setting bits for EPP mode, pre-loading parport drivers and then unloading before EMC, even setting the write flag for the device under /proc/bus/pci/??? I seem to recall, I got both computers running with MOSChip based cards (9845 I think). Once I managed to force them into mode, I did not have to repeat it all at every start up. What I did find however, was that 2 of the cards recommended (SIIG and Sun1188) would not work in input mode no matter what I did. This despite both functioning as such if used with Mach. There were also differences in getting the card to work under the same version of EMC ( seems to make no difference which one you use), almost identical computers (same make model, just 4Mhz difference in processor speed).

It is not >inconceivable that a given lathe might have both front and back tool posts, like this arrangement here: Yes, I didn't explain myself very well.

I think I tried this previously, just done it again and it is only partially successful. Whilst the part profile is now above the Z centre line, with home position above and to the right, mimicking the view with the tool is approaching from above on a slant bed lathe, the dimension bars and the X0 Z0 intersection marker are displayed above the home position, in a mirror to the part profile. I deleted the emc.var file before start-up, loaded a file that just contained M2, homed to homing switches then 'touched off' to an approximate X0 Z0 in G54 prior to loading a file with some code, but despite the fact that the tool moves and cuts the profile as it should and returns on G28 to 'home', the rest of the display remains in a mirrored position relative to 'home' which matches a conventional front tool post lathe. Will have to look through the source code again and see what GEOMETRY= changes and go from there. I may just have to stick with the conventional view and transpose it in my head. I long since stopped thinking about CW and CCW arcs where lathes are concerned and just view them as convex or concave, which assists greatly in programming the correct G code irrespective of the view you are presented with. regards -- All of the data generated in your IT infrastructure is seriously valuable.

[Emc-users] [emc-users] Changing Axis display to cater for lathes with slant-bed or rear toolpost
Hi This subject has come up before but to no obvious conclusion. The current display can be adapted to by the programmer for linear turning, but it is when turning arcs that the orientation of the display becomes a problem and renders the display near useless. Looking at OpenGL, it appears that a projection can be rendered in different orientations, however my lack of any detailed knowledge of python and miniGL did not assist in browsing axis code in search of the lines in which this projection could be flipped to a mirror of the current default rendering. Can anyone with a deeper knowledge of the code comment on the possibility of adapting the existing rendering code or would it require a complete re-write? There must be a lot of users out there with slant bed type lathes who would find this very useful. The devils spawn - Mach - has this facility, but enough of the profane language. regards -- All of the data generated in your IT infrastructure is seriously valuable. Why?

Then they could be indexed in a simple array. In the absence of text manipulation and substitution routines in gcode, the easiest route is just to number the subs and find an easy way of remembering what they do, if you want to set up an array of them which can be addressed. regards -- All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.

Hi
I think you are heading down the classic ladder path to achieve your
overall end, but I don't recall seeing your having solved the initial
problem of executing scripts etc from a M1XX command.
I had some problems getting hal commands to run within a bash script
called from M1xx, a while ago.
First off, unless your controller computer is permanently connected to
the internet, (why would you, hardly going to improve latency) just log
in as, install as and run everything as root.
Sorts out all the problems with permissions, ownership etc. The
'middle-man will get you' paranoids will argue against it, but for a
stand alone computer, I really do not see the problem.
Obviously ensure that M1xx file is in the path pointed to by
PROGRAM_PREFIX in your .ini file
If somehow you have 2 entries in your .ini file, EMC only reads the
first one.
Wonder how I found that out!
If you launch EMC as child process within a terminal (ie without the
trailing & ) you will get stderr etc from emc and any processes launched
from within it, eg bash or your C program.
It was seeing this and using debug outputs, that enabled me to discover
that EMC reads M101 P3 and then passes 3.00 instead of just 3, to my
M101 script!
As an example the below M101 script uses calls to halcmd to adjust the
scale and stepgen associated with my spindle, to account for pulley changes.

Re: [Emc-users] AXIS to close open "Tool Change" popup
Hi On my lathe, I have completely changed the tool change behaviour, removed the AXIS dialog from the module and just implemented tool number updating via AXIS. In doing so I found that the tool change dialog is displayed by hal_manualtoolchange, which is a python module and as such is directly editable within the EMC file tree. It uses TKInter libraries and looks like TkInter dialogs just need :- 'dialogname'.initial_focus.focus_set() and 'dialogname'.grab_set() to grab focus and become modal dialogs.

[Emc-users] EMC2 v2.4.3 G76 change?
Hi Downloaded and compiled the above to 'run-in-place' , just to see what had changed etc. Have previously been using v2.3.0 from the cd image. Thus far functioning as expected with one exception. When I ran a test threading file, I got an error for setting 'I0' ie thread peak = 0 This works fine under 2.3 and seems the only sane setting if you have turned down to finished diameter before threading. Since a dialog pops up that specifically says I cannot be zero, the logic has obviously changed from 2.3, but the documentation has not. I changed I to -0.001(mm) which made damn all practical difference and the code was accepted and works. The DROs showed the 0.001 has been subtracted from the X diameter in all passes. Perhaps the documentation needs to specify that 'I' must be a signed value and if the driveline is already at the thread peak, it should be adjusted by +/- I to compensate. regards Schooner -- This SF.net email is sponsored by Make an app they can't live without Enter the BlackBerry Developer Challenge http://p.sf.net/sfu/RIM-dev2dev ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
Re: [Emc-users] Lathe ATC integration
Hi Again, Just an update to the thread with the solution adopted. I hate searching threads and never finding how it ended up being done. I wrote a G Code sub routine called which takes 2 parameters, current_tool and required_tool. This is no problem, as when you do a tool change you will always know what tool you were using previously. (often just tool1 from the initial machine homing) This sub calculates the number of moves between tools, the number of units required for each move, based upon the tuning of the A axis and the slightly differing distances between tool stations. It moves the ATC forward to just past the required tool and reverses back to stall against the pawl. Using G Code overcomes all the problems of trying to move a previously defined axis during a M6 command. It then calls M6 Tx to match the required_tool. I have linked a hal component I have called hal_autotoolupdate as per below. *loadusr -W hal_autotoolupdate net tool-change iocontrol.0.tool-change => hal_autotoolupdate.change net tool-changed iocontrol.0.tool-changed <= hal_autotoolupdate.changed net tool-number iocontrol.0.tool-prep-number => hal_autotoolupdate.number net tool-oldnumber iocontrol.0.tool-number => hal_autotoolupdate.oldnumber net tool-prepare-loopback iocontrol.0.tool-prepare => iocontrol.0.tool-prepared* hal_autotoolupdate is simply based on the hal_manualtoolchange python script, hacked to remove all the dialogs etc. Since the tool change has already been done when M6 is called, all I want the component to do is pass a tool-changed signal back without any operator input, so that the tool number and offsets are updated. You could just feed one into another, as in the ..tool-prepare line, but I wanted the pins available for a pyvcp addition to my set up, to clearly display tool change and offset info. This works perfectly and should work for any similar Boxford, Emco or whatever, that uses the same type of methodology for its ATC. My lathe conversion is now complete and fully functional. I have learnt a lot on the way. Thanks for the help and advice, particularly Andy Pugh for his help getting a threading pulse circuit working.

Re: [Emc-users] Lathe ATC integration
Hi again
I have spent a few days reading all the manuals etc and studying the
various links you all passed on.
I decided that Kirks solution of a component written in C was most
viable for me.
In the interim I have written a G Code sub routine called m6 which does
the tool change and I just have to do a M6Tx to get the tool number set
correctly from the manual tool change module.
Gets me by for now.
Below is my idea of how I could achieve the tool change with a component
and the associated .hal entries.
Before I start trying to test it, I would be grateful if you could run
an eye over it and tell me if I am going in the right direction.
There could be an absolute howler in there and I currently am not far
enough up the learning curve to know it.
Also, does EMC or Axis store the current tool number somewhere that can
be read or will I have to implement some sort of .conf file to hold that
very necessary data?
With no encoder etc, the whole operation hinges on knowing the start point.

Re: [Emc-users] Lathe ATC integration
Hi again Thanks for the various links and info, I will have to sit down and try to get my head around them and work out the best strategy John and Steve are correct about the way it operates. It is a Boxford 240F and really it does not matter whether the motor loses steps when locking back. The important thing is to know where the ATC is, ie locked back against a pawl on tool no X, not where the motor is. The holding torque of the stepper is more than enough to ensure the ATC does not move once up against the pawl. In Mach, I just set the tool number up to the current tool at startup. Then the macro moved x amount for each tool position and having reached the required one, it moved back y amount to lock back against the pawl. This worked fine, especially as the distance between each tool is not even, from cutting tool to drill is slightly shorter than drill to tool. Odd to even moves were one amount and even to odd another. 360 degrees divided by 8 would have been too easy! I could put an indexing switch by tool 1 and 'home' the ATC at startup. This is the arrangement it had originally with a Fanuc control. However that proximity switch and just about every other bit of low voltage stuff was burnt out, the control had suffered a power outrage. Does EMC store the current tool number somewhere that can be read and written to, or will I have to implement that? Thanks again, I'll see what I can come up with. regards ArcEye > > I admit that I don't quite see how these tool changers are supposed to > > work.

For an 8 position turret you have a ratchet with 8 teeth and a spring-loaded pawl. Assuming you know where you are now (say tool 2) and each click needs 100 steps. To move to tool 5 you output 330 steps. You now know that ratchet is about 30 steps after a "click". Send 40 reverse steps. The stepper stalls, as you say, but you are in the known position for tool 5. Next move to say tool 6 just outputs 130 steps forward and 40 back. John Prentice Sorry, but the pawl is essential to how it operates. The counter rotation is limited by the pawl to the exact position where the tool should rest. These tool turrets will only work with the spindle rotating in the normal direction, pushing the tool back against the pawl, but they do work well for such a simple design. They were used by Southbend, Emco Maier, and many others.

[Emc-users] Lathe ATC integration
Hi Guys, I have been searching the lists for info on setting up an ATC under EMC2. I have found some references but nothing concrete as to how it is achieved. This must be quite a common requirement, but can see nothing in the wikis etc about doing it. I have an 8 station revolving tool changer, powered by a larger stepper motor with a rachet and pawl arrangement to lock (go past pawl and reverse back against it to lock) I set this up simply in Mach, by writing a M6 macro, pity most other things in Mach are so flaky. Want to be able to code M6 T101 and have it turn until tool 1 is selected etc. The ATC is currently assigned to axis A, so I could just write GCode to achieve the same result, but would rather it responded properly to M6. Can anyone point me to some info or tell me the secret?! thanks ArcEye -- This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?

[Emc-users] SIIG PCI 1P parport card
Hi again, Just want to see if anyone has any ideas I have not tried, to get this card working with pins 2-9 as inputs under EMC2. It works perfectly with Mach and was connected to my MPG pendant with pins 2-8 plus 13&15 in use. I bought it because other users recommended it as a proper IO card which worked, not just a printer card. Under EMC I can load it as "0x5800 in" and hal creates all the right pins, but only 10,11,12,13,15 work as input, so no different to saying "0x5800 out" I have scoured the previous posts; I have downloaded the EPROM utility from SIIG and set it to EPP. (This card now has a XP utility to do it instead of a old DOS one, lot easier) I have also written 0x80 to 0x5c00 which should do the same, using the pcisetup.c code someone posted previously (had to change a couple of bits to account for different header locations, but seems to work fine) I have loaded the linux parport modules before EMC and then unloaded them as someone suggested for a MosNet card. Net result, an afternoon of frustration and then I wired up to pins 10, 11 and 12 to X/Z, 0.1/0.01 and Estop and got a working pendant. I did have a pyvcp panel set up in Axis, to enable mpg-x mpg-z and Jogging ratios. This worked perfectly, except that I needed to turn back to the computer to change axes, which was not ideal. Failing any other ideas, can anyone recommend a card which works fully under EMC. A twin ported card might be good, don't need any serial ports. regards Mick -- ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
Re: [Emc-users] Single Index Pulse Threading
Hi again Managed to get an hour in the workshop unexpectedly, linked encoder.0.Phase-Z to the index pulse as well and eureka it works properly, let threading tests commence! May yet fit the encoder, will see what you think of the one I have.

[Emc-users] Re Single Pulse Threading
Hi Andy, Steve and Dave Thanks for the replies, I see from the initials that you (Andy) are the person who posted this solution in the first place. I didn't realise that the last line had wrapped, the spindle-index-enable line isn't wrapped normally, must have happened when pasting into the email. It will be a couple of days before I can try this out properly so I will come back to you then. The timing magnets will not be perfecting in phase. Mach only requires 1 long pulse and 3 shorter ones, which I achieved with different sizes. The time between is not critical and whilst they will be pretty much 90degrees apart, it will not be exact I do have a small 6 channel encoder available, but its resolution is 2500, which even I with my limited knowledge thought might be too fine. My max speed is 2400rpm but normal working speed does not tend to go above 1200 and threading not above 600, so do you think this might be a feasible? It requires a line driver circuit, which is what I assume Dave is refering to, I did have a schematic for one somewhere. regards Mick Date: Fri, 23 Apr 2010 18:00:55 +0100 From: Andy Pugh Subject: Re: [Emc-users] Single index pulse threading To: "Enhanced Machine Controller (EMC)" Message-ID: Content-Type: text/plain; charset=ISO-8859-1 On 23 April 2010 17:12, Schooner wrote: > > loadrt encoder num_chan=1 > > addf encoder.update-counters base-thread > > addf encoder.capture-position servo-thread > > setp encoder.0.position-scale 1 > > net spindle-position encoder.0.position-interpolated => motion.spindle-revs > > net spindle-velocity encoder.0.velocity => motion.spindle-speed-in > > net spindle-index-enable encoder.0.index-enable <=> > > motion.spindle-index-enable > > net spindle-pulse-and-index parport.0.pin-11-in => encoder.0.phase-A > > encoder.0.phase-Z ;set to correct pin.

In this case you need to link the encoder A-phase to your pin-11 so that EMC can calculate a spindle speed, and also the Z-phase (which is the index pulse) to the same pin. > > I included the above into my .hal minus the last line. > You need the last line.

For transient signals you should use Halscope, it works a lot better. It is one of the most useful tools in EMC in fact.

Incidentally, I think you have speed and no index rather than the other way round. I think you might also need to add a line: setp encoder.0.counter-mode 1 to the HAL to tell it to not look for the B-phase.

[Emc-users] Single index pulse threading
Hi My first time here, hope you can assist. I have a working stepper driven lathe under Mach, but am not happy with Mach on many levels and use Linux for everything else, so am migrating to EMC2. I have all the basic stuff working, but I cannot do any threading. I have a single pulse from the spindle from a hall-effect sensor. (On the opposite side of the pulley I have embedded 4 magnets, 1 x 10mm and 3 x 4mm, which if the pickup is shifted, give a 'timing pulse' which works with Mach, so could use that set up) I found an archived reply on this forum as below to a very similar query /"You need an index input, as EMC doesn't start a threading pass until it sees an index. Looking at http://www.linuxcnc.org/docview/html/examples_spindle.html (the last section) I think you need at least the following lines added to your HAL loadrt encoder num_chan=1 addf encoder.update-counters base-thread addf encoder.capture-position servo-thread setp encoder.0.position-scale 1 net spindle-position encoder.0.position-interpolated => motion.spindle-revs net spindle-velocity encoder.0.velocity => motion.spindle-speed-in net spindle-index-enable encoder.0.index-enable <=> motion.spindle-index-enable net spindle-pulse-and-index parport.0.pin-11-in => encoder.0.phase-A encoder.0.phase-Z ;set to correct pin. " /I am afraid I do not understand how encoder.0.phase-Z could be connected to anything, there is only one index pulse. I included the above into my .hal minus the last line. The lathe still does not start a threading cycle and if I watch the spindle-pulse-and-index, it does change but only every 5 seconds or so, not continuous flickering as I would expect. If I rotate the spindle manually, I get a positive indication every rev, so maybe the hal monitor display just cannot update quickly enough. Have I missed something or is the answer that you cannot thread with just an index pulse and you must have a timing pulse too, connected to encoder.0.phase.Z perhaps?? Would my 4 magnet set-up through a second pickup provide that, if a timing pulse is required , or is that too coarse? thanks Mick -- ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
