Mach4 General Discussion / Backlash not applied during manual JOG?

« on: January 01, 2016, 10:12:24 PM »

I've just built a new G0704, using Mach 4.

Here is a link to my backlash test

As you can see in the video I can cycle 1 inch off zero and back to zero with no drift.    When I approach zero with my indicator zero my X axis and back off zero, there is backlash present during my jog moves.   The DRO shows movement, and no table movement.  I expect backlash values to be applied to Jog moves as well as MDI commands.

Am I missing something?  am I crazy?  shouldn't manual Jog moves be backlash compensated as well?

Thank you
