Reference print on the left. First sliced Tablebot print to the right. Not sure if the problem is calibration or kinematics. Either way we are changing the arm design. The tool chain has been proven and the surface quality is good.
It is because your arm is tilted. The arm should be horizontal at all times.
@Mano_Biletsky_Open_M Hahaha. Just to be clear, the arm has to be tilted to have an infinite build volume.
Looks like your using a tilting motion for you z axis. That is introducing arc in that axis and would need to be compensated out, examples indicate it was not. Side note, surface quality may suffer with non-virtical aligned tool.
@Trae_Greenlee We have compensation but it obviously needs some tweaking.
The nozzle is perpendicular to the layers. Surface quality is actually pretty good.
