Galil / Bug in Galil Found While Jogging with Keyboard Arrow Keys

« on: January 11, 2011, 03:54:26 PM »

When I jog the machine using the arrow keys on the keyboard, I get a runaway condition quite often. It will start jogging, and then just go crazy, zipping along down the table at breakneck speeds. I just looked at the code in the GalilDebug.txt file. I noticed that many of the commands don't have a comma between the value for the Z axis and that for the A axis. I think this is causing my problem. An excerpt from my GalilDebug.txt is attached.

My config is as follows:
4 axes: X,Y,Z,A - all servo reverse
X and A are slaved together (X is the master)

Has anyone else ever experienced this? Please advise.

Galil / Problem with Homing - Mach and Galil

« on: December 24, 2010, 09:14:33 AM »

I am having difficulty getting the homing to work properly on my machine. All the home switches show up in the diagnostics screen and respond as they should. My Z axis homes fine. But when I try to home my Y axis (home neg is checked in homing and limits screen), the head comes to its homing sensor, the input light triggers in the diagnostics screen (it actually slows down briefly) then it keeps on going the same direction and pushes against the stop and faults the servo instead of backing off the sensor and setting that position as zero. Any ideas?

Galil / Need Help with Galil Setup on DMC-1842

« on: December 23, 2010, 12:30:42 PM »

I need a little with a Galil setup here. Here's my situation:

I am switching a machine over from a proprietary front-end software to Mach3, but using the same Galil card and wiring the machine has always had. The machine works at this moment, with the old software, so it should be pretty straight forward to get this going. Here's what I need to know:

------------------

QUESTION 1: Where do I tell mach3 what my encoder counts per inch are?

---The motor tuning dialog will not let me enter anything.
---There is nowhere in the plugin config where I can set it.
---I can only set the encoder units per rev for the spindle in there, but that setting doesn't apply to me.
---I called Galil's tech support, who told me they deal only with encoder counts, not real world units. They leave that to the front-end software. So where do I tell mach how many counts to use to go an inch, especially as it is different for my Z axis than my X axis?

------------------

QUESTION 2: One of my axes has a slave. Axis 1 and Axis 4 (X and W or X and A) are slaved together. What is the best way to set that up? Do I do so through Galil commands in SmartTerm, in Mach3, or a combination of both?

------------------

Thanks in advance for your help.

Galil / Control Synrad Laser with Galil DMC-1842 via Mach3 ?

« on: December 21, 2010, 08:22:50 AM »

I am working with a machine that has the Galil DMC-1842. I understand that will work with mach. This machine however, has a synrad J48-2S laser on it driven by their UC-2000 laser controller. I want to set it up to do not only vector engraving, but raster engraving as well. Is that do-able? Anything I should be forewarned about?
