I would make X home switch 0, home position -0.1 and negative travel max -8 and positive travel max -0.1, I think.
(Because PnCConf won't let you change the home switch location)

In later versions the PID values are not alterable, but the P-Gain is fortunately set to the right value.

like this?

I duplicated the x on the z with smaller axis length value

next window is the spindle

my encoder has an A channel, a B channel and an Index, 1800 pulses
I assume the direction is called by a pin, not by pos,neg voltage

That seems wrong, and I thought that 8" cross-slide travel seemed a bit much for an Emco.

Z is saddle, X is cross-slide.

And both mills and lathes the Z axis runs along the axis of the spindle.

I was able to get the toolchanger working. over the past couple weeks its been quite a battle learning and implementing the programming to make the toolchanger turn on command T1 M6. I got that working 2 days ago. then spent another couple days getting it to work with buttons on GUI. But success last night.

time to work on the spindle. hooked it up to my first guess and nothing. manual buttons NO, M3 NO. I am not sure if I have the VFD setup or wired correctly or if I have a program issue. so here are the culprits.
