You've modified the button press moves to add 235 instead of 3... That's why it's going outside the boundaries. Our GCode only moves 3mm to press the button after it moves to the holding location.

Bill

And let me clarify... the code is issuing the G91, which is moving from Absolute mode to Relative mode... but is still issuing Absolute commands, instead of our relative commands. G91 ; move to relative mode

M83

but then issues this

G0 X235 F2000

Which is moving from it's current position + 235mm... so, if it was at 100, then it's trying to move to 335mm on the X axis, which is undoubtedly causing the out of bounds condition.

Our code doesn't do that... when it's in relative mode, it only moves X3 and X-3 to engage the button and disengage the button.

G90 is absolute mode, which if you changed the first line, should make this work, but you'll need to be consistent with it's usage throughout your tool change gcode.
