Need help with basic MPG set-up and 1750 card
« on: February 15, 2011, 11:27:53 PM »
I could use some help setting up an MPG for use on my mill driven by a Galil 1750.  The first three axis are used for X(A), Y(B), & Z(C) and the spindle is on D.  I have the MPG wired to the auxiliary encoder for the E axis and it is enabled in the plug-in. 

I have enabled the MPG #1 in Mach3 with the port set at 1 and the pins for A & B at 0.  The MPG works very roughly by using the TAB screen.  Each MPG step gives 0.0125 inch of travel on any selected axis when the "cycle jog step" is 1.000, 0.100, 0.010, or 0.001.  If the "cycle jog step" is set to 0.0001, each step of the MPG results in 0.008 on an axis. 

I have tried changing the MPG counts/unit and velocity settings in Mach3, but it doesn't seem to do anything.  The "Calibrate MPG" wizard under the Function Cfg's menu doesn't seem to work either.

Does the encoder channel for the MPG need to be set-up in SmartTerm? 

What am I doing wrong?  Any help is appreciated.

Jim,

Enable debug in the plugin config dialog and do some MPG moves.  Then send me the resulting GalilDebug.txt file.  My email address is in the plugin documentation.
