G1 Xnnn Ynnn Znnn H1 Sense endstops while moving (ignoring the axis limits). On Delta (only), axis letters refer to individual towers.

Hi,

Perhaps you are thinking of M564?

...........or simply G1 X-nnn Y-nnn Z-nnn to move in the negative direction. The title question is a bit ambiguous so we can only guess the answer.

I think you want to change your axis limits in your config.g file...that would be the M208 line.

This is what I have for my BLV CoreXY printer

; Axis Limits
M208 X-2.5:340 Y-0:328 Z450 ; X carriage moves from -2.5 to 340, Y bed goes from 0 to 328

Basically when my carriage hits the x endstop the nozzle is -2.5mm left of my bed and the max movement I want to the right is 340mm... my y homes at the max which is 3mm past the back of my bed which which is 340mm wide x 325mm deep..
