Re: [Emc-users] Esc key
No, I actually use the flood for coolant and the mist for an air blast I use on plastic parts I think then an M9 would stop the motor also - which might get confusing for an operator On Wed, Aug 15, 2012 at 8:53 PM, Chris Radek wrote: > On Wed, Aug 15, 2012 at 08:24:32PM -0600, Brian May wrote: > > I use the esc key alot to stop programs or turn off the spindle - > almost like a reset key.

[Emc-users] Esc key
I use the esc key alot to stop programs or turn off the spindle - almost like a reset key. Is there a pin where i can bring this into classic ladder? I have a live tooling motor that i turn on with a custom m-code (m103). I would like it to turn off when i press the esc key. I currently use another m-code to turn it off. Which i want to keep - but would also like the esc to work.

I use it and it works good. It is much easier to generate the g code in cam, there are not a lot of lathe specific canned cycles yet.

Re: [Emc-users] Lathe Threading
Yes, I am supplying from an external source and have the jumper set so that the encoder is powered by the external source. I have to buy another encoder anyway for my live tooling - so I will get one and see if that fixes the problem...

Re: [Emc-users] Lathe Threading
that is the correct encoder. I just verified the part number on the encoder itself. It was working for measuring RPM with the jumper in the TTL position (Where it has been the whole time). I just moved it to the Differential position and it still measures rpm fine. But, the index is still not working for the threading... However, I am learning this as I go and not sure if I need to do something different since it is a differential line driver type encoder?

Re: [Emc-users] Lathe Threading
I looked at the configuration CHNC and it looks the same. I followed andy's advice and found that the z-pulse is on pin 4. So I connected pin 4, (Z Pulse) to an encoder component A phase (encoder.0). Then set the encoder component to counter mode. So now I have the encoder using the hostmot driver and also the Z Pulse being read by the encoder component. I turned the spindle on at 120RPM and expected to read the counter of the encoder component counting 2 counts every second. It did not, It is not counting reliably. Only at like 4RPM (turning by hand) does it count reliably.. Shouldn't the threading start when it finds the Z-pulse, even though it might be inconsistent? Or does it need it to be consistent? In other words - could I just connect a button to pretend to be the Z pulse and when I press the button it starts threading? (I tried this and it did not work...) To me it looks like I either have a cable or encoder problem. But am still confused why it would not work at all since it is getting a signal every once in a while Thanks for the help Brian On Sat, Jun 9, 2012 at 5:11 AM, John Thornton wrote: > I have my CHNC lathe converted using 5i20 7i33 7i77 and all the wiring > of the cards and my config files are here if you want to compare notes. > > http://gnipsel.com/shop/hardinge/hardinge.xhtml > > John > > On 6/8/2012 8:39 PM, Brian May wrote: > > I am having trouble setting up threading on my lathe.

Re: [Emc-users] Lathe Threading
It is wired up. I don't really know how to see if it is working.. I tried connectimg it to a io port and create a latching circuit in classicladder to see if it was sending a signal. I turned the encoder by hand and it would latch the circuit every few turns. I may have had a timing issue... So i know that there is a signal... I do not see in hal a index pin for the 5i20 component.

[Emc-users] Lathe Threading
I am having trouble setting up threading on my lathe. At this point I am thinking my spindle encoder is bad. I have the following setup in my HAL File: net spindle-revs hm2_[HOSTMOT2](BOARD).0.encoder.01.position motion.spindle-revs net spindle-vel-fb scale.0.in motion.spindle-speed-in hm2_[HOSTMOT2](BOARD).0.encoder.01.velocity net spindle-index-enable hm2_[HOSTMOT2](BOARD).0.encoder.01.index-enable motion.spindle-index-enable My Parameters are set as follows: setphm2_[HOSTMOT2](BOARD).0.encoder.01.counter-mode 1 setphm2_[HOSTMOT2](BOARD).0.encoder.01.filter 0 setphm2_[HOSTMOT2](BOARD).0.encoder.01.index-invert 0 setphm2_[HOSTMOT2](BOARD).0.encoder.01.index-mask 0 setphm2_[HOSTMOT2](BOARD).0.encoder.01.index-mask-invert 0 setphm2_[HOSTMOT2](BOARD).0.encoder.01.scale 1024 For everything else, the spindle has been working fine. I have been running in G96 spindle speed mode, the RPM that the encoder reads is perfect. However, when I try and do a thread, the process never starts. The machine goes to the start point and just sits there and waits. I am assuming it is waiting for an index pulse and never receives it. From what I have read in the manuals - when the index pulse is found, the motion.spindle-revs goes to zero during a threading cycle. On my machine this never happens. It just continues to count. I ran my G-code in the lathe sim and it seems to work fine. I am using a mesa 5i20 and a 7i33 daughter board. The encoder is connected to the 7i33 board. The encoder is an automation direct TRD-N1024-RZVWD.

How can I see, what the numbers for the work offsets are and which work offset I am using?

[Emc-users] gladevcp tabs
I might be missing something obvious, but how do I add a second gladevcp
tab in the axis window.
I have in my ini file:
GLADEVCP=-u hitcounter.py right_panel.ui
EMBED_TAB_NAME=offsets
EMBED_TAB_COMMAND=halcmd loadusr -Wn gladevcpoffsets gladevcp -c
gladevcpoffsets -u hitcounter.py -x {XID} offsets.ui
This works fine and gives me the panel on the right and a tab named
offsets, just as expected.
However, i also want to add another tab named "tool changer". If I add
another EMBED_TAB_NAME=tool changer it gives me an error. In the manual it
states that several independent GladeVCP panels may be run in different
tabs... But, I have not been able to find an example of this...

That is why I am asking the question. I am reading what I can and asking different people before I do anything. I am in no hurry and not planning to wire anything until I understand what I am doing. Currently I just have the 3 phase power to the VFD and the rest from an extension cord in the wall. It works, but I would like to improve the design. I have to learn somehow and will probably ask beginner questions So far people have given me further links to read and different things to search on google to understand better. > To make it clear: grounding is the up and down of electrical power > application.

Re: [Emc-users] 3 phase power
Yes everything at our shop is wired off 3 phase. But our box has a nuetral. So it goes from leg to nuetral. However my machine only has 4 lines - the 3 legs of power and an earth ground. So i guess my question is do i need the nuetral?

[Emc-users] 3 phase power
This is probably an easy question for alot af the people on the list. I have 3 phase power going to my vfd on my machine. I want to the use that same power to power all the 120 single phase components. (the dc power supply for the steppers and varios other motors. ). This way i only need 1 plug I have been reading and people say i can go from 1 leg to a nuetral or leg to leg.

Re: [Emc-users] Simple homing question
This is kind of off the subject but may be useful in future releases. On haas machines they have a parameter called grid offset for each axis. Basically it is a parameter that will "offset" the index pulse. This way you can control where your machine zeros without having to fool with the encoders. When you set it, the control tells you how far you moved from the switch to the index pulse. Haas has a value that all machines need to be. Like 0.1 inches from switch to encoder index. In the grid offset parameter you enter the number of pulses to "shift" the index pulse to get the 0.1 On high pitch ball screws the location of the index pulse could move your zero a lot. They did not want people messing with the encoders and causing other problems so they have the parameter. Anyways That is my 2 cents Sent from my iPod On Nov 3, 2011, at 7:26 PM, Tom Easterday wrote: > > On Nov 3, 2011, at 8:21 PM, Dave wrote: >> Did you throw in the towel on the hard stop homing with the drives?? > > No, and n fact I think what we are going to do is to try to manually align > the index pulses on both encoders and let the Granites do hard stop, then > find index, then move to specific position (they can do all this themselves), > then bring EMC online and just tell it "you're homed". > > -Tom > -- > RSA(R) Conference 2012 > Save $700 by Nov 18 > Register now > http://p.sf.net/sfu/rsa-sfdev2dev1 > ___ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users -- RSA(R) Conference 2012 Save $700 by Nov 18 Register now http://p.sf.net/sfu/rsa-sfdev2dev1 ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

[Emc-users] G43 and G54 Lathe
I am confused on G43 and G54 for a lathe. I am confused on how G43 works with G54 for a lathe. I set all my tools on the Z axis to the spindle nose (G54 Z is set at machine 0 or variable 5223 is 0) Then I take tool 1 and place it at the end of the part and touch off the Z axis G54 at 0. This sets my variable 5223 to lets say 1. From what I though, That 1 would then be added to all my tool offsets to give me that actual zero. So far everything is working and I make a part. Then I add another tool and touch of the end of the tool to the spindle nose and my Z for that tool is incorrect? It is located very similiar to the other tools in location of Z, however the number in the tool offset is very different and it does not go to the correct location If there is something for G54 in the Z axis, does this effect the tool offset G43 when setting it? Am I wrong in thinking that G43 should be from machine 0? The sequence I take when setting the tool is: in MDI I type T7 M6 G43 Then set the tool Should I not do the G43 when setting the tool to the end of the spindle nose?

[Emc-users] C-Axis on lathe
Hi All, This may not be the correct place to post this, but if anyone has experience with this maybe they can help me out. I am trying to test my C-Axis on my lathe by just cutting a simple flat. I am cutting a 1in diameter bar of aluminum and trying to cut a flat that is 0.325 from center to the flat. I am programing it by hand as I do not know how to do it in CAM. I have never programmed using XC, I always used to do it with G112 But it looks as though that feature is not in the EMC software. I am using a .375 endmill, The center of the tool is the center of the part. Anyhow, I am not getting anything that looks like a flat - the problem is, I do not know if it is problems in my machine, configuration, or problems in my program I would like to eliminate the program as the problem. Here is the basic move codes that I am using. % g54 t6 m6 g43 m154 g20 g8 g94 g0 x1. g0 c-110. g0 z.1 g0 x1. g0 z-.1 g1 x.783 c-130.853 f1. g1 x.5125 c-180. g1 x.803 c-230.347 g0 z.5 g0 x2.5 g0 z1.

Re: [Emc-users] Why do we need G43?
yes I think you are right but why not just M6 T1 H68 instead of M6 T1 g43 H68 To me, the H implies a height offset because I do not think I use H any where else to get it confused with another G code? But whatever, in the end it is no big deal and maybe the standard is to have G43 On Wed, Oct 12, 2011 at 4:22 PM, Daniel Rogge wrote: > > > On the mill (HAAS) you use the G43 Hxx for whatever tool you need.

Re: [Emc-users] Why do we need G43?
On the HAAS lathe you do it like this T0101 which is tool 1 with offset 1 or T0115 which is tool 1 with offset 15 The G43 is implied and you never have to use it. On the mill (HAAS) you use the G43 Hxx for whatever tool you need. Not sure why you need the G43, it seems redudant since I cannot think of another instance where I use H Maybe just tradition.

Re: [Emc-users] Lathe tool offsets
I think that is the problem so simple On the HAAS Lathe I do not have to set the G43 - it is automatic. I am going to give that a try.

[Emc-users] Lathe tool offsets
I am having a hard time understanding how the tool offsets work on a lathe With our HAAS machines, For the Z I set each tool to a fixed point on the machine. Then I set the diameters by machining a bit and measuring the diameter. Then I set the G54 Z to the face of the part and leave the G54 X at machine home. I am trying to follow this same procedure for EMC and cannot seem to get it to work. I set my G54 X to machine home. My G54 Z to the end of the part. Then I set my tool 2 (cut off tool) Z to the spindle nose, (fixed point) (which is where all the tool offset Z are set) and X using the cut a diameter a measure method. (basically the same method I use on the HAAS) However, my relative position on the EMC screen never seems to change reflecting the tool. If I set T1 and T2, then in MDI type T1 M6 - I am thinking that the position should change... from the T2 position. Every time I try and run a program I get an error that I am exceeding the limits? I have been reading the manual but cannot seem to see what I am doing wrong? The lathe is a gang style table.

[Emc-users] Spindle controller with GS2 Driver
Hi All, I am using the GS2 driver to communicate to a automation direct GS3 motor controller. It seems to be working fine. However, I need to set the parameter spindle-vfd.nameplate-RPM in a hal configuration file and I keep getting errors that says the parameter does not exist. Once I load EMC I can go into the hal configuration and set it there - but for some reason I cannot set in the HAL file. Any ideas what I am doing wrong?

[Emc-users] Engaging C-Axis on Lathe
Hi All, I am still working on engaging my C-Axis on my lathe. Everything is basically working except one small issue. Because the way my design is - the best way to engage the C-Axis is if it is turning slowly. This will ensure that the everything meshes together. This is where I am having problems. My first idea was to just make a simulated encoder and when a M154 was enacted to jog the C-axis using the simulated encoder as a jog wheel. However, this is not working because it will not allow me to jog an axis while in MDI or run mode (which makes sense...) Then I though that I can just zero the axis which actually works better. I command a M154 - the air solenoid opens and the C-Axis slowly moves into position. Through Classic ladder I change the state of the halui.joint.5.home bit, (which initiates a zero routing). While the C-Axis moves into position the C-Axis motor is turning slowly looking for zero. I use the index pulse on the spindle motor encoder as my zero pulse on the C-Axis. As the C-Axis engages - it starts turning the spindle and then finds the pulse and zeros. This really is ideal because now every time my C-Axis engages it is in the exact same position allowing me to avoid keeping track of the spindle... However, I get the following errors: In run mode Can't do that while in (EMC_AXIS_HOME) in auto mode with the interpretor idle. Then in MDI mode Can't do that (EMC_AXIS_HOME) in MDI mode. Any ideas of a work around or better idea? Thanks -- Brian May 506.2293.6375 (Office) -- Special Offer -- Download ArcSight Logger for FREE!

Re: [Emc-users] Alarms
I currently do inhibit it from happening. I use a custom M154 to engage the C-Axis. In classicladder I have it set up that if the spindle is turning (regardless if it is on or not), then you cannot engage the C-Axis, likewise I have it set, if the C-Axis is engage then you cannot turn on the spindle. My concern is, that someone will have the C-Axis engaged - not realize it and try and turn the spindle motor on and not understand why it will not start - and then try and "fix" it and cause damage. I guess I could set up some LEDs on a panel - which I should do anyways. I guess my more broader question is if you could set up custom alarms We have some HAAS machines and you can setup macros and they have a variable that you can use that allows you to set custom alarms. I will play around a bit and see what I can find. I will try that component that les sent also.

[Emc-users] Alarms
Does anyone know if it is possible to make custom alarms? For example I have a C-Axis motor and a regular spindle motor on a Lathe. I would like if the user commands the C-Axis motor to engage while the regular motor is turning to E-Stop and give an alarm. I can tie it into the e-stop circuit easy using classic ladder - but what I would like is to also display a message telling the user why it went into e-stop mode. I would also like to do this for low air pressure Thanks -- Brian May -- Special Offer -- Download ArcSight Logger for FREE!

Re: [Emc-users] Lathe questions
Hi Andy, I am using an automation direct GS3 drive with one of their 3HP Micromax motors. Down the road I think I am going to try your suggestion. I am currently running the motor with a PWM signal - but in the process of changing to the serial port and using the GS2 driver - which looks like it will work for the GS3. (I guess I would have to stick to PWM if I wanted to try and control it like a servo?) Anyway - I would like to get the stepper working for now - I already built the parts and installed it so want to see it work Either way I do it, I am still confused on how to do it, I have to set up the c-axis in the ini file and the hal files. Right now I have Axis0, Axis1, and Axis2. Axis0 is the X Axis 1 is the "y" axis which does not exist and Axis 3 is the Z. I am required to zero "y" axis in the Axis gui, (even though it really does not exist). Which from what I see just zeros itself and that is all. So would I just create an Axis 3 as a rotary axis - if so that is simple enough? How can I name it "C" because I think it would default to "A" which, I believe, on a lathe is the turret? - which maybe does not matter Thanks for the help On Sun, Aug 28, 2011 at 9:44 AM, andy pugh wrote: > On 28 August 2011 16:00, Brian May wrote: > > I would like to add a C-Axis.

[Emc-users] Lathe questions
Hi, I am new to the mailing list, but have been using EMC for a while now. I just completed a small lathe and have it pretty well working with EMC2 version 2.4.6 on ubuntu 10.04. I would like to add a C-Axis. (I already have it built and attached). Basically, when wanting to do live tooling work, the C-Axis stepper motor engages on the spindle driving the spindle instead of the spindle motor. When the lathe is turning parts the C-Axis motor disengages. There is an encoder attached to the spindle so I can keep track of its location. My ultimate goal would to be able to do C-X-Z moves to create flats, milled grooves and so forth on the parts. However, right now I have a need to just index the spindle 30 degrees and drill a hole - (which is a pure X move). i have not been able to find much information on this. Does anyone have any ideas or at least a direction I can start moving in?
