Have have recently built a lowrider 3 CNC with a duet 2 wifi board. it has been a challenge to get it all configured but i think I'm getting close. the usable area is 49 x 97 and after checking it for square with diagonal measurements its about 2 mm off. On the V1 site it mentions using M666 to adjust the long side. it uses 2 y motors so I'm not quite sure where or how to correctly use it to adjust the long side after homing.
Any thoughts?
