I think having the m208 y38 in tool change files is what caused it. I removed that and it worked. Thanks.

It's just M208 Y38. I didn't use the S parameter. I also remember now that I disabled M208 in the mesh.g file so it shouldn't be that. It's weird how tool 0 worked but tool 1 isn't. I might have removed the m208 from tool 0 and that's why.

@dc42 I'm not by my machine now but I think it grabs the tool then moves to Y100.

@dc42 I noticed I have M208 Y38 in my tpost files. The thing is when I was using tool 0 it was printing but the z offset was always different because of the dock mount was loose. The only other thing I did was try scanning z probe. I'm thinking I didn't change your mesh.g file and my 0,0 is the front left of bed.

config.g 3dbenchy-1-TC.gcode

I keep getting this error when trying to print on my tool changer. It moves z to 0.2 then moves to 0.8 and keeps doing this until I stop it. It is extruding filament while doing this. I also tried the 3dbenchy gcode file from e3d and it does the same thing. I'm using tool 1 because working on tool 0 but i selected tool 1 in the slicer. I also tried changing my z axis min to -1.0 but it still does it.

@dc42 thanks. Now I just have to figure out how to read registers. I checked the driver data sheet but still don't understand it

Is there a way to see what the hend and hstrt plus all the other settings for the stepper drive?

@dc42 I was trying to test z probe scanning but it seems the probe is reading wrong. It says 22768239 under z probe on dwc dashboard. When I run G29 K1 it scans the bed but the max deviation is 1256mm and after it's done scanning it keeps lowering the Z axis until it bottoms out and grinds.

@dc42 that fixed both of my issues. Thanks.

@dc42 alright thanks. I'll give it a try in a bit.
