Set x offset ?

[peter247]

Hi , if my end stop triggers at say X -15mm and is off the bed , do I use G10 P0 X15 tool offset to set where the start of the bed is ?.
Normally I would just move the end stop or set the position in my homing files.

@peter247 just change the axis minima/maxima in your M208 commands in config. When you home, it just sets the stopped position to the max/min value depending on whether you have high end or low end endstops

@engikeneer I think M208 is for setting the Max and Min limits , But you have lead the way to the right command which I do believe is M206 ; Offset axes.

No, he's quite correct. If your endstop triggers when the nozzle is x-15 off the edge of the bed then your M208 minima for X should be M208 X-15. This would place X0 on the bed again and leaves the X maxima the same.

M206 is not what you're after.

@phaedrux I get the sense in that after a lot of thought .
If when it hit the end stop it says -15mm then X 0 is where I want it 15mm + from the end stop.
So what does M206 do different or what is that for ?

It's a precursor to the G10 offsets you identified in your first post.

Maybe it will work, but it's an overly complicated way to do it when M208 is far more elegant.

M206 is an obsolete command equivalent to the NIST-standard G10 L2 P1, i.e. set offsets of workplace coordinate system 1.
