[Emc-users] Emc2 2nd hard drive not recognized
Using Emc2 off of the Live cd and updated to 2.1.7, I installed a 2nd hard drive but the file browser does not see it. It is detected okay in the bios. What could be the problem?

[Emc-users] COMP_FILE trouble
I am using version emc 2.1.7 and tried to use the comp file feature and got the following results. When I homed the axis using that file the axis began moving in the direction of the limit switch but before it got there it reversed at full speed and was heading toward the opposit limit. When I hit E stop and it didn't stop. I had to hit the main power switch to the stepper driver to get it stopped. Upon reapplying power to the driver the motor on that axis didn't move but made a strange high pitch singing sound. After closing emc2 and then reopening it,the motor sounded normal (a5khz hum is normal when it is motionless), I was able to jog the axisl, however when I tried to home the axis it repeated the runaway. Resetting the ini file back to using backlash comp the system performed flawlessly. Does anyone know what is going on? I have included the pertainent section of my ini file and the comp file below: Jack Ensor #+ First axis X [AXIS_0] TYPE = LINEAR HOME = 0.000 MAX_VELOCITY = 1.5 MAX_ACCELERATION = 2.0 STEPGEN_MAXVEL = 1.7 STEPGEN_MAXACCEL = 2.2 #BACKLASH = 0.0024 COMP_FILE =comp1.fil COMP_FILE_TYPE = 0 INPUT_SCALE = 2500 OUTPUT_SCALE = 1.000 MIN_LIMIT = -13.

Re: [Emc-users] EDM question from a noobie at it
Gene - I think that if you were to build a dam around the part with modeling clay and fill with kerosene might help speed things up. Keep in mind that kero is flammable so take care. Just my 2 cents worth - I've never done it. By the way, I submitted an article to Digital Machining describing my stepper motor resonance damper. Don't know when or if it gets published at this point.

I now have the work insulated, a copper wire in the chuck bent to wobble about enough to cover the ends of the taps, and tried a 50 volt AC supply for about 20 minutes, but the transformers were way too puny and have already smoked. I have an air jet blowing on the work, and the wire running about 200 rpm. While it worked, I'd guess I got rid of 5 thou total, from the work and the electrode wire end, so its not gonna be exactly a 5 minute job unless I can get some more effective firepower into it. Figuring that DC, with a current limiter of sorts and a storage capacitor to hold more bang will probably work better, I've resigned myself to building it. The question then is, for an air quenched lashup, what is a suitable voltage, and a suitable current limit in terms of average milliamps, that I should try and build? Googleing doesn't seem to spit that sort of info out readily. Look at my info at http://jelinux.pico-systems.com/edm.html You need a current-limited supply of DC to a film-type capacitor to deliver the current pulses that do the EDM work. Also, I think a dielectric fluid is really important to make the difference between welding and EDM. I run 30 V at about 1 A, mostly due to the parts in my EDM power supply. I found alum-tap (an aluminum tapping fluid) works great, although it is flammable. I only keep a couple drops of it in the hole at a time to reduce the risk of a big fire. (I did get it to flash once, but it did not sustain a fire, so it must have some fire retardant or vapor suppression in it.) Water won't work unless it is really pure. Some people have reported plain distilled water works well. Jon Thanks Jon, that is about what I was looking for. I noted that the wiki seems to indicate an rf generator is often used, with frequencies around the 500 khz range. That almost sounds as if it would setup a plasma that would never be quenched. And while that might cut at a higher rate, this sounds a whole lot simpler. Is the quality of the capacitor that important? I see you wrote film in the text, but showed paper on the drawing. I can borrow a big oil filled can with 8 or 10 uf, rated at 8 to 10kv from our transmitter spares. My motor psu is 29 volts, and if I can cobble up a suitable limiting resistor, and in this case a 100 watt light bulb comes to mind as it will also light dimly to show the short status, then that home-made psu can serve as the current source. It can certainly spare that portion of an amp. I don't have anything that looks or sounds like aluma-tap, but I can certainly source a gallon of distilled water, or I have a quart of ACE hdwe thread cutting oil which will probably work, and has already contaminated the area. I didn't have any plastic rod to hold the wire, a hunk of 14 gauge from some handy romex, so the work rather than the electrode is insulated, a couple pieces of scrap formica are padding the vise jaws a small strip of cherry under the bottom edge. No leakage that I can measure. Slightly shocking to the touch though, I allowed my sweaty arm to lay on it at one point. :) The wire is currently rotating with a small clip lead attached, which seems to work but shows some wear where the clip sits already, but I like the idea of the much stiffer brass, so I'll see if I can src a hunk of smallish brazing rod while I'm out doing the honeydo's this morning. What I have on hand is too big, 1/8 IIRC, so I didn't even think to dig it out. 3/32 would be ideal I'd think for a 6-32 taps web diameter. But with the depth I have to go, probably nearly 3/4 for one of them, the cleanout will probably have to be done with an air hose after I get down the first 1/8. Might even have to rig a stinger from a wd-40 can somehow and get right into the hole. Fun and games... With an air jet and 50 VAC with no capacitor, I was only able to go with a f0.0003 feed. If I can get 0.010/min out of it, that would be great in comparison. Thanks Jon. - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems? Stop.

[Emc-users] emc2 strange behavior - Reboot cured it
Today I was monkeying around with the resonance dampers on the x and y axis and eventually I asked it to do a home and the y axis froze. I immediately assumed it had something to do with damper adjustment or maybe some file changes I had made trying to fine tune things. But after resetting every thing to what was working, I found that y axis still wanted to freeze on rapid moves and still would freeze even though I slowed it down by a factor of two. X axis also exhibited the same behavior although not to the extreme degree as y axis. I also noticed a peculiar sound would gradually begin to appear when rapid moving and I could feel a vibration in the whole machine(Bridgeport) when it was about to freeze. Then I noticed in the axis display that the tool symbol was not moving steadily and had a shakiness to it. After rebooting, all these symptoms disappeared and the system was back to its old self again. I don't know what brought this misbehavior on, but was wondering if halscope would be able to show what was happening particularly if there were excessive jitter in the signal.

[Emc-users] ini axis comp file usage
How is the COMP_FILE = file.extension used in the Axis mode of operation? I tried creating a table (comp.fil) as follows to see the results and get an idea of how it works: -13. -13.000 -13. -5. -4. -4. 0. 0. 0. The appropriate portion of the ini file: BACKLASH = 0. COMP_FILE = comp.fil COMP_FILE_TYPE = 0 HOME_OFFSET = -13.2 HOME_SEARCH_VEL = -1.0 HOME_LATCH_VEL = 0.05 HOME_USE_INDEX = NO HOME_IGNORE_LIMITS = YES HOME_SEQUENCE =1 After homing the axis under test I went to the MDI mode I entered g0 x -5.0 and expected to get motion to the position of -4.00 since I had defined that in the COMP_FILE table. However the final position went to 5.00 indicating to me that the table was ignored.

Jon I assummed that using my table mounted DRO I would be able to calibrate the system and use the COMP_FILE to correct for my backlash which varies according to table position. I was wondering if Emc interpolated for the positions between values listed in the table, but at this point it seems that COMP_FILE isn't working even for values listed in the table.

But it really went to -5.0 on the DRO. hrmm, that doesn't sound like it should work ;) try mangling the comp file by purpose (it needs to have increasing values from one line to the other, if you put in a smaller number than on a previous line you should get an error). That error will prove that the loading of the comp file is actually working, and there's something else screwy.. Please tell us what version of emc2 you're using too.. Regards, Alex The EMC2 versionis 2.1.5. I set up a table with actual measured values. 1st col is nominal, 2nd col is actual table position read from table DRO when nominal is called while moving in a positive direction, 3rd col is actual actual table position while moving in a negative direction. This was done without a COMP_FILE and backlash set to 0. This is the table: -13. -13. -12.9970 -8. -8.0010 -7.9997 -5. -5.0010 -4.9970 -3. -3.0010 -2.9970 0. 0. 0.0030 3. 3. 3.0030 5. 5. 5.00030 8. 7.9995 8.0040 13. 13. 13.0045 The backlash shows in the table and at the extreme positive end increases from 0.003 to 0.004. Now when I move the table for example if I am at nominal 0. and table DRO indicates 0. and I issue g0 x-3, I would expect that after the move the table DRO to indicate -3.000, however it indicates -2.9970. Sure the EMC says -3. as it should. So it looks like the table values are being ignored. - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML. No limits.

[Emc-users] Suggested value in ini traj section
The suggested value in the ini file Traj section for a 3 axis mill for MAX_ACCELERATION seems excessively high. The way I figure it for a coordinated move, the maximum would be 2 times the individual axis rate (assuming that all axis are assigned equal values). In my particular case with a maximum value of 2.0 for each axis, a value of 4.0 should be satisfactory for the Traj section. Any comments on this?

Re: [Emc-users] Suggested value in ini traj section
I think you missed my point. I figure, the assignment for MAX_ACCELERATION value in the traj section would be dependant upon what values one has specified in the indivdual axis section. That is if you have a 3 axis machine (mill) and have assigned 2.0 for MAX_ACCELERATION values for each axis in the axis sections, then why would one assign 20 for MAX_ACCELERATION in the traj section when the greatest possible coordinated move acceleration is 4.0 due to indivdual axis limitations? Note in the manual in paragraph 5.3.6 states The [TRAJ] section contains general parameters for the trajectory planning module in EMCMOT. You will not have to change these if you are applying EMC to a common three axis mill in the US.

The accel numbers will depend on the machine - the suggested values are just that, suggestions. You need to decide what is right for you. If your maximum velocity is 2.0 (2 inches per second, assuming an inch machine), and your accel is 4.0, then it will take one-half second to go from stopped to max speed. For some machines that might be exactly what you want. Other machines can go from zero to max speed in a tenth of a second or less. And some very massive machines may want to do it even slower.

Yes By jumps all over the place you mean it is totally unpredictable how far off it will be? Yes If you make several 1 moves in the same direction with incremental jog, what is the error? Zero, ignoring backlash when giving it individual G1 or G0 commands. Does it accumulate or all appear at one point in the series of moves? I am using axis.ngc to test it with. At the end of the programmed moves, I compare the Axis control panel positions with my DRO and get greatly varying differences each time I run it. I always do a home all before each run and the DRO is consistently on 0 +/- .001 before I start the run. To make it easier to compare the differences I changed the last move command in axis.ngc From: G00 Z #1To: G00 Z #1 X0 Y0. Before start of run after homing the DRO reads: X: . Y: .

Jon Elson wrote: For speed: The max jog speed is set in emc to 90 ipm (1.5 in/sec). When jogging at the max rate I measured a step frequency of 813 Hz on phase A. Calculating the table speed: 800 pulses/sec x 60 sec/min x .0004 in/step = 19.2 ipm However just by looking at the table move, it is moving much faster than that. Is this because due to the nature of quadrature drive, the table actually moves 4 times faster than the step rate? Yes, precisely. Every change of either A or B is a full step of the motor. 813 Hz should give 3252 steps/second, or 78 IPM. I'm not sure why you aren't getting the full 90 IPM you are requesting. Well it's probably because of my halscope measurement. When using the fast thread for a halscope trigger, it retriggers when the buffer fills. Consequently when you stop the jog it begins decelerating and the buffer can fill and cause a retrigger during this phase. I tried to get around this problem by hitting machine off as I stopped jogging. So the reading I got in halscope I'm sure was probably during the beginning of the deceleration period. Using a real analog scope I measured about 1 Khz. This calculates to 96 ipm. So at 90 ipm my scope reading should have indicated a period of 1.06 millisec = 938 Hz. This is within the accuracy of my reading the scope and its error.

[Emc-users] How much is too much jitter?
I noticed when jogging at my maximum rate of 90 ipm the 2 quadrature signals coming at a rate of 1 Khz have approximately 50 micro seconds of jitter. Is this excessive? How much would it contribute to tracking error? My tracking error is insignifcant when homing but but huge when running Axis.ngc.

Is this excessive? How much would it contribute to tracking error? My tracking error is insignifcant when homing but but huge when running Axis.ngc. Would you please define this term tracking error? I do not know what it means. From context, I believe you mean to say the machine's position differs from the displayed position. Is that correct? Yes, position displayed on the axis screen differs from what my dro says except when I home they always agree. How are you seeing the quadrature signals? On a box oscilloscope, or somehow with halscope? Unless halscope AND the software or hardware encoder input facility is sampling at a fast enough rate, you would miss some of the edges. Yes, I understand the hal (storage scope) better now. When I used the faster sample rate, I then got more resonable results For instance, on my minimill, at 60 IPM, with 16 TPI leadscrews and 4:1 motor reduction, and with 500 CPR encoders producing 2000 counts/revolution, you get 128,000 counts per second. Therefore, counts are coming at a rate of one every 7.8 us. Obviously, my jitter must be less than yours. But, a scope would need to be sampling it at a rate of once a microsecond or better before you could even begin to discern jitter on the signal. If you are using an analog oscilloscope, then there is no sampling. But, without specifying the rate of encoder pulses when you see the 50 us jitter, it is hard to know what it means. If you had 50 us jitter when the count rate was one millisecond, it is not a big deal. If it was when the count rate was 50 us, it would be reducing the quadrature angle to zero, and would clearly cause errors. So, you have to compare the jitter to the count rate. The rate as I originally stated was 1 Khz which translates to a pulse period of .5 milliseconds low and .5 milliseconds high. So I suppose 50 micreoseconds jitter isn't too bad then. (About 5%). Ideally, there should be 90 degrees between the 4 states of the encoder's A and B signals. They never are, due to tiny errors in the manufacturing of the encoder's optics. The greater the error, the narrower some of the count states become, until they become so small the encoder counter's logic misses them. Then, the position will be off by multiples of 4 counts. When you say homing is OK, but axis is bad, is that all due to speed? Slowing things down by a factor of ten makes no difference in position error. It still jumps all over the place. Could you explain why the following speed calculation is in error? I have a unipolar motor, driven in quadrature phase A, phase A not, Phase B, and phase B not., where phase B lags phase A by 90 degrees. Motor plate specifies 200 steps/rev step down from motor to screw: 2.5 to 1 Screw pitch: .2 in/rev .2 in/rev x 1/2.5 rev/rev x1/200 rev/step = .0004 in/step. This is correct because this is what I see the system do. For speed: The max jog speed is set in emc to 90 ipm (1.5 in/sec). When jogging at the max rate I measured a step frequency of 813 Hz on phase A. Calculating the table speed: 800 pulses/sec x 60 sec/min x .0004 in/step = 19.2 ipm However just by looking at the table move, it is moving much faster than that. Is this because due to the nature of quadrature drive, the table actually moves 4 times faster than the step rate? This would put it more in the ball park of what I am seeing.

[Emc-users] Whats wrong with Halscope?
I've been trying to pin down follow tracking error in that after I run Axis.ngc my dro doesn't agree with the position according to the Axis display. After trying many things as far as acceleration and velocity settings I thought maybe I ought to take a look at what was coming out of emc. Using halscope connected to the parport pins that drive the motor driver I could't believe what I was seeing. As I jogged at maximum velocity hal showed an increasing frequency as the table accelerated, but then the displayed frequency decreased after the acceleration period and then increased again as it entered the deceleration phase, finally decreasing to zero as the table stopped. If the halscope scaling is correct, the max frequency reached was around 400 hz during acceleration and deceleration After the acceleration phase the frequency slowed to zero as the table stopped. The rise and falltimes were 0.5 ms. Yes 500 uS.! Maybe I should mention that I am using the quadrature stepper. I then looked at the signals with a real scope and didn't see that anomly. As expected, the frequency increased as the table accelerated reaching a maximum of 1 Khz after the acceleration phase and decreased to zero as the table stopped. Rise and fall times were less than 1 uS. So maybe the problem is I don't know how to use halscope or maybe its frequency response is very slow. Can any one educate me on this?

See the integrator's manual which describes how to use it. The manual may be slightly out of date regarding the available inputs, so use halcmd/halshow to examine them on a running EMC2. Chris I don't have enough input pins left on the on the my three parallel ports unless I reconfigure some of the ports to input. This means a complete replacement and rewiring of of the existing flat cables and reprogramming and checkout of the now working system. Another alternative may be to add another parallel port board to provide more parallel ports. The current add-on board which provided 2 parallel ports, had the addresses preassigned and adding another identical board would surely have an address conflict. How can I add additional parallel ports and avoid address conflicts?

[Emc-users] Bridgeport loses sync running axis.ngc
I have finally gotten to the point where I am running my bridgeport on Emc2 and have spent time tuning the software parameters to what I thought were optimum. When I home the x and y axis, they home within .001 in. consistently. I have a DRO to monitor table position. I am running with a max velocity of 1.5 (90) ipm and max acceleration of 2.0. The motors are Superior Electric Slo-Syn 840 oz-in 200 steps per rev with a 2.5 ratio to the ball screw with a pitch of 0.2. This worked out to a scale of 2500. The driver boards accept quadrature signals from the three parallel ports. However when I run axis.ngc, the ending x and y positions are at variance from the commanded positions and each time I run the program (after first homing), I get different variances. I calculated the variances by subtracting the actual position from the commanded position and x can vary from -.148 to +.009, while y can vary from .063 to .008. I tried reducng the acceleration to 1.0 , reducing max velocity to .75 and changing the cutting rate from 60 to 5 in the ngc program and still no significant improvement. I can't figure out what is causing my setup to behave this way, and wonder if any one has any ideas on this or has come across this behavior before?

I looked at the Sharp web site (http://www.sharpusa.com) and was not able to find an 8.4 monitor other than those using standard VGA, etc. inputs, for which no additional drivers are necessary. Alternately, I recently checked into head an interface which supports 4 line x 20 character displays such as those available from matrix orbital (http://www.matrixorbital.com/index.php?cName=lcd-mx4-series) and Crystalfontz (http://www.crystalfontz.com/products/index-usb.html). The interface is dependent upon lcdproc, which provides drivers for these and many other LCD displays. It is certainly not ready for prime time, but you can look at it by using the ncurses interface (I can send you the configuration if necessary). You will need to do a checkout and compile of head, since that is the only place it currently exists. Then either start LCDd (LCDProc Daemon, see lcdproc instructions) manually or put it into the startup script. Lastly, in one of your hal files, add the following line: loadusr emclcd And then run EMC normally. It is still in its early stages, so there is some other information I would need to supply, like key mappings. In a 4 line x 20 character display it provides information such as the current program loaded, dynamic X, Y, Z positions, progress bar, run, pause / resume, stop, step, etc. functions, as well as a menuing system for accessing other parameters and settings. Let me know if this is of interest to you and I can provide additional information. Regards, Eric I've been looking for a small flat panel monitor for mounting on my machine control panel for my EMC Bridgeport controller. Sharp has an 8.4 inch LCD panel that would be perfect except a driver or interface board would be needed to interface with it. I haven't been able to find any boards. Does anyone know of any or have any suggestions for finding a small flat panel at a reasonable cost? - Take Surveys. Earn Cash.

Re: [Emc-users] Error-Unexpected realtime delay
It looks like I have a problem with smi (system maintenance interrupts) increasing the latency and causing the realtime errors. Referencing EMC Documentation Wiki - FixingDapperSMIIssues they give these instructions: 3. Changing smi-module.c First you need to get the sources for the dapper version of RTAI: to get the sources for the dapper version you need to apt-get source rtai-3.3 Find the smi-module.c inside rtai/base/arch/i386/calibration, and change the following line: #define CONFIG_RTAI_HW_SMI_ALL 1 Once that is changed, you can compile the module and replace the version already installed. 4. Compiling the new module Unless you want to use the existing build process (which means you need to put the rtai sources in /usr/src/modules/rtai-3.3/ and use make-kpkg to build the modules) use the following Makefile: Makefile UNAME := $(shell uname -r) KERNEL26 := 2.6 KERNELVERSION := $(findstring $(KERNEL26),$(UNAME)) obj-m := rtai_smi.o rtai_smi-objs := smi-module.o INCLUDE := -I/usr/include/asm/mach-default/ KDIR:= /lib/modules/$(shell uname -r)/build PWD := $(shell pwd) all:: $(MAKE) -C $(KDIR) $(INCLUDE) SUBDIRS=$(PWD) modules Simply run make, and the new module should be built. (Alternative: grab the binary from [[here]]). 5. Installing the new module Installing means simply copying the new binary module over the old version, located at: /usr/realtime-2.6.15-magma/modules/rtai_smi.ko *** My question is do they simply mean down load the binary file and then copy it over /usr/realtime-2.6.15-magma/modules/rtai_smi.ko ?

Re: [Emc-users] Hal Implementation of a different enable
Thanks so much. show pin worked very well. I was able to discover what the pin name actually was and then incorporate it in my setup. I guess it should have been intuitive that you can do this while running a test program but I didn't get it from the hal manual. And this was after going through the hal tutorial. Jack Ensor Quoting John Kasunich [EMAIL PROTECTED]: HAL is designed to be very discoverable. That means you can easily find out what pins exist for yourself, rather than asking questions on mailing lists and waiting for people to tell you the answers. Comment out the line that is causing the problem (put a # in front of it) and then start EMC. Then open another shell (terminal window), and run halcmd show pin You will get a long list showing all the pins in your running EMC. You can scroll up in the list to find whatever you want (it is in alphabetical order). You can shorten the list by providing a partial name: halcmd show pin mo will show only pins beginning with mo, which includes all the motion ones. show sig can be used the same way, as can show param.

[Emc-users] halrun and parport problem
I am having trouble getting failures on pinout.hal. The indications in the error report indicate a problem with the parallel port. When I tried changing the default loadrt hal_parport cfg=0x0378 to my 2nd address of 0xdff0 and connecting my breakout box to the 2nd port, the led's on board didn't flash like they did on the first port. I then put the box back on the first port without changing the from 0xdff0 to 0x0378 in the pinout.hal and found that even though pinout.hal defined the port as 0xdff0 the signals were coming out on the first port.

Re: [Emc-users] 2.1.1 Upgrade?
I believe I was mistaken. It was probably after the 2.1.0 came out. Is there any easy way of checking for which version I have? Jack Ensor Jack Ensor wrote: I originally down loaded and installed the Live EMC2 CD back in the early part of January. I'm not sure whether you have the version 2.1 or 2.0 live CD. I checked, and 2.1.0 came out on January 28. So you almost certainly have 2.0, not 2.1. Just follow these instructions and you should be good to go: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?UpdatingTo2.1 Regards, John Kasunich - Take Surveys. Earn Cash.

Re: [Emc-users] Parallel port installation
Thanks for the info. Yes, I failed to say that I am trying to interface an add-on parallel port card. I knew there must be a way of determining what the offset addresses were. Can't wait to give this a try. Jack Ensor Alex Joni wrote: It seems that you are trying to use an add-on card (NetMos). There is a good description how to do that for emc2 in the wiki. http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?NetMos If you already looked there, and didn't find it, please let me know where you looked so we can make it more visible.

Re: [Emc-users] EMC2.1 Live CD
Thanks for all the help that has been provided. Yes the drive was too small and after switching ot a larger drive it installed fine. Now I need to work out details of getting dialup to work and the laser jet printer to work with it. I'm currently plowing thru that.

You need at least 2GB of hard drive space to install Ubuntu.

Re: [Emc-users] EMC2.1 Live CD
Does the Live CD for 2.1 install on a blank hard drive or must you already have Linux and what version installed? Jack Ensor Alex Joni wrote: The Live CD at www.linuxcnc.org has already been updated. You can download the new one, ang go that way.. but it's a 650MB download. The alternative only means 2-3 minutes of changes updates. Your choice..

I would like to upgrade to 2.1 but would feel much more comfortable with the live CD method and would have no problem completely replacing my system as I have a freshly formatted blank drive ready to go. Is there a plan for a Live CD version of 2.1 in the near future? Thanks, Cecil - Using Tomcat but need to do more? Need to support web services, security?
