After now 3 months of research, I disassemble / reassemble my problem concerning my offset in X axis and sometimes in Y but rarely, is still not resolved. I can not.
I tried everything, change, the belts, disassemble everything, the axles and reassemble according to the recommendations (Zortrax maintenance), but nothing changes. My printer always prints parts once very good and after that the next part is offset on the X axis.
I noticed something. During the automatic axis check, if I touch the print head a little bit, the motor slips. I am specifying the motor and not a belt. It is as if the engine does not have enough force.
I further specify that the engine is new. The axes are very free, no hard point, I can move them at the maint without problem. I also have the latest firmware, latest Z-Suite version.
I do not know what to do. I am disappointed with a CHF 5,000 machine.
