Hi, Can you provide specific pictures so that we can better solve the problem;
Maybe it is a gcode error that caused this to happen;
You can try reslicing and try again.

hello!....

I have done with different stl and different software. Motor Y are very hop when lst steps. Extruders lost steps… When start printing is ok, but after 15 minutos aprox. begin lost steps and with more time more lost and finally a big lost step in Y .

How Can I verify if the problem is in drivers?... or main power?..... or main board?.

Y is soft, not hard when I move manually.

Tell me info about how can I check for drivers,,, power supply and main board….

I think is a main board because is failure in motors E1, E2 and Y. this happen after a work for 11 hours.... i think damage electronic

Hi, Can you provide specific videos?

You can try to swap the driver board,
or use a multimeter to measure the driver board. The voltage range is 0.8-1.2v.

you can refer to this:

If your belt is loose, you can try to tighten it.

I have read V in all drivers:

Motor E1: 1.333v
Motor E0: 1.306v

Motor Z1: 1.218v
Motor Z0: 1.160v

Motor Y: 1.318v
Motor X: 1.147V


do you think this is the problem?
