Base config for Z axis for alignment

[PaulHew]

I am building my RailCore and would like to put some base code in the Duet so I can run my Z axis leadscrews independantly whilst I align the linear rails.

I was going to use an electric drill on the exposed Z leadscrew, but thought better of that idea!

Thanks in advance.

Paul.

The simplest approach is to assign each Z motor to be an independent axis. If you have your Z motors connected to the Z E0 E1 connectors on the Duet (and the extruders connected to the DueX), you would normally have this command or similar in config.g:

M584 X0 Y1 Z2:3:4 E5:6:7:8:9

To make the motors controllable as axes Z U V, use this instead:

M584 X0 Y1 Z2 U3 V4 E5:6:7:8:9

Temporarily put this in homeall.g:

G92 X0 Y0 Z0 U0 V0

then the firmware will consider that all axes have been homed and it will allow you to jog them.
