I not found a way on my machine to zero my X / Y after homing and have learned to live with negative values after homing. I recently started a new project and want to start engraving at a specific point on my bed (X -106.7 and Y -128.1). However, the Move Window “Move to Position” does not seem to permit negative values. Is there a work around or a way to save/load a preset position?
Your best bet would be just fixing your homing issue. Do you have homing switches, or do you just start the machine up in the correct position that you want your 0,0 at?
