General Mach Discussion / Pins assignments in MACH3 - need help pls!
« on: February 05, 2012, 06:36:58 PM »
Gentlemen,

I have been using Mach 2 with Geckos on a Bridgeport Series 1 machine for about two years now with nary a hiccup. Excellent results. Very happy.

I am now in the process of building a 4 motor (three axis, A slaved to X) plasma table and I am hoping to use the same controller to run these motors with MACH3 and a torch height controller.  MACH3 is ver. 3.043.022.   BOB is a CNC4PC C11G, it is running on 55 VDC through Gecko 203V's.

Of course, I am building a new machine configuration in MACH3  to run the plasma table.  I am only in the process of bench testing the motors with this same controller used for the Bridgeport and I am having a heck of a time getting the plasma table motors to run on the assigned pins/keyboard jog buttons.

I have been methodically cross checking my ports and pins assignements as I go, comparing them with my MACH2 plasma test configuration but even with identical pins assignment in Mach 2 and Mach 3, different motors run on jog tests. All of them run mind you, the correct ones run in MACH2, but not in MACH3.

I have been careful to save the setup, shut down the controller and Mach3 between config changes and jog tests but I am obviously doing something wrong. I'm kind of at wit's end at this point.

I have attached some screenshots.    Can anybody perhaps suggest some things I should check?  Thanks in advance.
