Hi All,

I used the demo file "scorpion.tap" to test my router table.
This file is part of the Mach3 demo version.
When the g-code is processed and the mill has to go back to it's zero point , it happens that the Y-axis motors (slaved-axis) seem to jam (it does'nt sound good  ).
The result is that the Y-axis does not go back to zero and I need to home the table again.

I'm quite sure that the settings in Mach3 are ok and both motors (y- and slave axis) are tuned exactly the same.
Jogging (fast/slow) and homing works ok.

Does somebody have an idea what could cause this problem?

Hi would appreciate if you have manage to solve your problem. I have been looking into changing my Chinese board problem and fitting a smooth stepper USB or Ethernet? How easy or tough is this to do , any wiring diagram set up would be much appreciated.
