[FR] Multi Material Automatic XY Nozzle Offset

[c3D-Dan]

Craftbot Idex seems to have the ability to automatically calculate nozzle offsets. Can this be achieved in Marlin?

To the best of my knowledge, it appears each nozzle has an endstop signal wire attached it.

Each hotend then touches the inside of a small circle cutout, at the front of the bed.
The difference in X/Y position of each is then calculated precisely, avoiding the troublesome manual calibration process.

To see an example of how it is done, please see here :

Right now, it’s a manual process using PROBE_OFFSET_WIZARD.

See #18866

Calculating the Z offset isnt the problem, that's always pretty easy. Its the XY offsets im talking about. See time 2:30 https://www.youtube.com/watch?v=NDvp8JoAuuo

HI @c3D-Dan .... maybe it's this setting ...

Why haven't I noticed that before? That feature looks like it might just be what we're looking for. I'll give it a go and report back.

Hi @c3D-Dan
How does it work ?
Is that what you were looking for?
