Galil / Galil Error 22 Begin not possible due to Limit Switch

« on: August 06, 2015, 05:35:08 PM »

OK, no matter what the configuration is, when I try to run G-code I get the LS error.

It works fine in jog from the keyboard, also I am able to jog from Galil Tools.  My MPG that is wired outside of Mach3 works just fine, Mach3 doesn't even know it's there.

Motors and encoders are all running the same direction, no problem there
Limit switches are wired Active Low, Galil is set to CN0=1
Active Low boxes are checked in the Galil Configuration
Debug file shows a CN 1 is being sent on startup
Again Keyboard Jog works fine

I have tried every possible configuration in the Ports and Pins config, including removing all reference to the limit switches.
I have also tried un-checking the Active Low boxes in the Galil config and tried every possible configuration in Ports and Pins

Again, everything works until I try to run g-code, and it still works after I try to run g-code.

Any ideas?

Thanks, Jim

Galil / Galil / Mach3 communications

« on: August 04, 2015, 11:05:16 PM »

I'm currently working on a milling machine project that is using Mach3 /Galil 4080.  This mill has a tool changer and I will be writing the DMC code to operate the TC.  I need to be able to run the TC program on command from Mach3, then notify Mach3 that the tool change is complete and it's OK to proceed.

The questions:

What does the Mach3 TC command to Galil look like?
Is it customizable?
How do I send a message back to Mach3?
Is there a listing of the messages that are generally passed between Mach3 and Gaili in normal operation?

I have over 20 years experience working with Galil hardware and DMC programming, but minimal experience with Mach3.

Thank you in advance for your help.
