Rob: a axis is along x, config is simple, just have to edit GEOMETRY = -AXYBC in ini file. i will send you a link sharing a folder in goog drive, theres config files and some sample gcode, just let me know if you can se it! theres no way i could run it smoothly, blending in rot axis is a must! there is a way to implement it? could you expand the need of non trivial kinematics in this case?, seems trivial to me. Regards rick
