G1/G2/G3: intermediate position outside machine limits

lparnell34

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.

@lparnell34 do you change the M208 X and/or Y limits in your tool change files to account for different tools having different ranges? If so then most likely when you execute that M208 command, the tool is outside those limits.

@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.

@lparnell34 so what Y value is the tool at when you execute that M208 command?

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

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.

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

@lparnell34 yes if you are at Y100 and you change the limit to Y38, that puts the tool head at a position that is no longer allowed. You should move the tool head to Y38 or lower before setting the limit to Y38.
