Mach4 General Discussion / Mach 4 / PMDX 422 Set Up - Limits and Homing

« on: February 21, 2016, 11:57:30 AM »

OK, Ive got all the limits and homing settings in.  Switches are checked and connected to the right pins (homing 11,12,13) , limits (A,B,C).  I know I could wire limits together but I chose this method.

I can jog on each axis successfully, and the machine reliably stops at the limit and home switches.

When I hit the 'home' button, the machine blows right through the home switches and hits a hard stop - regardless of the order of homing.

What is causing this, and how can I fix?

Thanks
