So, I have had mach 3 running a stepper converted hardinge CHNC lathe. Mach has (until today) been only controlling Z and X axis movement.
Today I finally got my collet closer running with a solenoid and a relay board through mach. additionally, I now have a VFD running the spindle through mach using my BOB's 0-10Vdc output. the only other thing I changed was to set up a mechanical estop.
These three new additions work very well, and relaibly. so far.
when I tried to run a working piece of code (created in Bobcad ver 23) I was stunned to find that my G00 moves were now so rapid that the G203V's I run were faulting out.
My motor tuning settings are the same as they always were, but now my G00 is super fast.
If I change my steps per for the Z axis from 40000 (the original always has worked correctly number) to 10000, the G00 moves are still very rapid, but are slow enough to not fault the G203v.
this has led me to believe that somehow, my settings for the max motor speed allowed are all messed up. I dont get it, I thought that the max motor speed (rapid) was a function of the motor settings tab. How can Mach be overriding this?
I tried switching a spare G203V into the system, but the G00 being wildly fast still happened.
I am attaqching 2 xml's one from 10 18 2011 which worked just fine when I saved it, and the other from today that allows me to use the CC, VFD spindle and EStop switch.
I hope you guys can help!
