Do you use the C23 BOB.

I only use PMDX 122, they have worked well for me without any issues so no need to change. I also use a CNC Building Blocks BOB on the lathe and Beaver Mill in conjunction with the PMDX but the reason was I was wanting Index homing which these boards did. I no longer use that feature as my servo drives can do that internally so if I was doing it again I would just have 2 PMDX 122's.CNC Building  Blocks is no longer making stuff anyway so they are no longer an option.

Hi,

I'm seeing something with my set-up that looks suspiciously like this thread, but it's with a new ethernet SS.  I was wondering if a solution was ever found?

My setup is a CRP-4848, ESS (V0), PMDX-126.  Homing acts very oddly if I enable the A-Home switch in Mach3.  Sometimes the X-axis will continue to move back and hit the physical stop or the A-axis will move forward after the X-axis moves off the X-home switch.  I do not have homing slaved in the General Settings.

Home works if I disable the A-Home in the Ports & Configs, but it won't square the gantry.

Hello,
I just installed a new ESS and the homing procedure have simillar issues.
Does anybody know how to fix the homing with slave axis?
Homing for X, which is a single driven axis work well but homing Z (and B, which is slave for Z)  or Y (and C, which is slave for Y) does not.
Issues are very simillar with the issues already described in this topic.

Thanks,
Seb
