Can't seem to get the z-axis motors working.

rsbkh

I've working on a scratch built corexy printer for a while now and am in the process of working out all the kinks with using a duet2 wifi board. I've finally managed to get my x and y axes to home properly using limit switches. I was going to use a bl touch for the z-probe but that won't do anything right now so I disconnected it and installed a limit switch for the z-axis as well. When I select home z nothing happens. Not sure what I'm doing wrong on this one and could use a bit of help on how to approach this. Thanks

@rsbkh please post your config.g and homing files. Also test Z movement by sending these commands:

G91
G1 H2 Z10
G1 H2 Z-10

The first G1 should raise the print head or lower the bed by 10mm. The second should do the opposite.

OK, Here are those files. I don't have the wifi working yet but using the manual move feature on the panel due won't move the z axis.

@rsbkh homez.g homey.g homex.g homeall.g config.g

The Z axis won't allow you to manually move it until it's been homed. You can force it to be homed to a position with G92 Z100, then you can use the commands DC42 gave to see if the Z motors are moving at all.

Could you also provide the results of M122 and M98 P"config.g" please?

Seems there was a bad wire connection. LED's are now on for the z-axis motors and I can get it to move up and down now. Looks like a bad connection on the extruder as well but I'll take care of that tomorrow.
Any advice on getting a BL touch to work properly?
