Define area for Mesh Compension Question

Theboz1419

When it ask for my bed area, I put the following

X=0
X=170
Y=10
Y=230
X spacing= 10
Y spacing= 10

For some reason it will not start at Y10, it will go to Y28 and start probing.

When I home, it will show Y-2.0, so I know I have to fix that. Should it not still start probing at Y=8.

So, I changed Home so that it reports the it's X0 Y0, when I home.

I added

M557 X0:170 Y20:220 to the Config.g file

But it still will go to
Y39 and start the probing, it won't start at Y20.

For some reason when I put

Y20:220

It will start at Y39 and when it will continue to Y239.

So it's offsets

How do I fix this issue

@Theboz1419 it does apply the probe offset to the position

Where is this probe offset? how to change it. It only applies to Y and not X or Z

@Theboz1419 its part if the G31 probe definition

@oliof Thank you. Yeah for some reason I have

G31 X0 Y-21 Z0

I have not clicked on the links in your last post, but I believe G31 to be the offset of the z-probe.

When I first installed the Duet on my Makergear M2 I had to print a mount for the Probe and I did have the offset on the Y axis. My new print I have it on the X axis. Now, I understand, thank you very much.
