Z tool offset in relation to the probing offset?

clegg78

I am trying to wrap my head around Z offsets, I have an IDEX with nozzles offset by .55mm (taller on the U axis) from one another. The BLTouch is on the X and is calibrated fine for that at Z1.65 listed in the G31 command.

So.. for the G10 command in defining tools... do I just list the .55 as the Z offset for the U Axis? or would I need to do Z1.15? for the U Axis?

Trying to figure out if the G10 reset the offsets from what G31 does. That also changes how I would need to define my Tool change files.

Current code: (Z Probe section)
G31 P500 X16.5 Y-27.5 Z1.65 ; Set Z probe trigger value, offset and trigger height

Tool definitions in the config:
Tool0: (X axis)
G10 P0 X0 Y0 Z0 ; Set tool 0 axis offsets
Tool1: (U Axis)
G10 P1 X0 Y3.55 Z.55 ; Set tool 1 axis offsets

Choose one of your tool Z offsets to be zero, then specify the Z probe trigger height and the Z offset of the other tool relative to that.

Note, in firmware 2.02, tool offsets are not applied within the tool change files. In firmware 2.03beta3, they are.

If you want to do ditto or mirror printing, you will need to get the two tools at the same height.
