HMM....
I took a look at  the XML, and also tried playing with it.
I may suggest the following. Make a modified xml with all the fancy stuff off ( PWM, HOMING SWITCHES,SURGE PUMP, ETC). Set the the A axis up as not slaved and as an index or  spindle.This way you can tell that the drive / cabling is all workiing. Back to basics kind of thing.....
Then add in one by one all the other stuff.

if you do that "emulate the  Estop and also disable the spindle / or  finish the associated
configurations. the spindle settings will overide the a axis settings for A as an indexer

FWIW,
RICH

RC dont think the DRO will show any movement as you are not really moving the A Axis, you are moving two X axis :) You should however see the A axis dir pin change state when you jog X and also see a voltage when jogging the X on the A step  pin.

Hood, yep, you're right.
I didn't want to unplug my printer to check the voltage on my sim pc so I temporarily reconfigured my small lathe.
Slaved A (used X motor) to Z and it works just fine, just no #4 dro movement.
You know me, RTDM first. That's how I get confused.  :P

It must have been changed internally somewhere along the line and no mention made of it.
All is good,
Thanks
the clip is from the new manual.....same as the old one.

Well, I finally figured out what the problem is. The 4th Axix stepper driver in my Gecko is bad. I took the X and A axis boards and swapped them out, restarted mach3 and guess what happened? The A motor turned and the X did not. Just to be on the safe side, I tried a different motor on the X axis, no joy... So Gecko Folks, if you are watching, I need a new driver board!

Hello,

Have you made a special script to test prox switches on both drives to square the gantry when homing ?

Kind Regards,
