I just built an MPG and all seems to work fine except there isnt any difference between STEP/VELOCITY and plain old VELOCITY ONLY modes. I am under the assumption
that STEP/VELOCITY mode is supposed to act like VELOCITY MODE until a certain velocity is reached, then turn into a mode like MULTI-STEP or VELOCITY ONLY depending
on whether you are slowing the axis down or speeding it up.The MPG is interfaced with Mach3 using MODBUS, in case that has an impact on Machs performance. I have also
experimented with the values for the STEP/VELOCITY percentage and it made no difference whatsoever. The axis always act like they are in VELOCITY MODE only, there arent
any definitive STEPS when I would expect to see them, just real slow velocity.

Any suggestions would certainly help me out.....I'm sure there may be others with the same experience.

Thanks
 

I dont think the Step/Velocity mode works correctly, in fact I dont think it ever did.
