Hi,
Is it possible to replace the original motors with Creality? I tried to change the one of the extruder (BJ42D12-11V01) with a creality 42-40 (BJ42D22-23V01) by modifying the vref from 0.69volt to 1.35volt but the motor stops rotating after the skirt when the first layer.
Thanks.
I bought a sv01 pro used for next to nothing with a sprite pro extruder kit on it. The seller said it will not extrude and he has given up. It literally does the same thing you mentioned. It prints the raft normally and then stops extruding.
I have turned up the vref voltage to 1.02 and still am getting the same issue. I have a second motor I can swap out if I burn up this one so I am not concerned with that. I am not convinced this is our issue though.
Did you ever solve your issue??
