Hello!

I try to make kinematics like in 3dp fdm 3d printer only with belt. In original they use screws:


I made drawing with reference to original coreXY kinematics, tell me where I made mistake?


There is only X axis where extruder moving and Z axis where all vertical portal move up and down. Could be this reproduce with coreXY kinematics?

Z cant work like that

Although z can be manually moved up and down. this doesnt result in rotation of the steppers. And the reverse is also true, with X fixed you cant rotate the steppers.

I suggest you search this forum for "CoreXZ". There is at least one thread on this subject.
