@sgk where the pivot points are for where the bed or gantry is secured.

@jay_s_uk
And is there also a relation to these lines or not?

@sgk those lines are where you probe the bed near to bed/gantry pivot positions.

@jay_s_uk Excuse me, I'm lost, what is the M671 used for? And how can I have the right dimensions for the M671 how to do?this is my bed 350x350x350

@sgk On the photo I have 2 axes but now I have 3 axes the photo was before.

[jay_s_uk]

@sgk its probably going to be the ball screw positions for your printer.

See M671 in the Gcode dictionary.

The X and Y coordinates in M671 are measured from the origin X0,Y0 set by M208. Measure to the pivot point of the bed where it connects to the Z axis. This is often each leadscrew, but may also be offset from the leadscrew if the bed rests on a carriage extending out from the leadscrew.

See https://docs.duet3d.com/User_manual/Connecting_hardware/Z_probe_auto_levelling for a longer description.

Lay on marbles

@droftarts I looked at the documentation but I can't understand why I'm asking the group for help

[droftarts]

@sgk In your case, the centre of each 'marble' is the pivot point of the bed. So:

The X and Y coordinates in M671 are measured from the origin X0,Y0 set by M208. Measure to the pivot point of the bed.

Your description of the positions here does not match your photo.
