I’m having some problems with my 3D printer and need some help.
The problem is that the nozzle constantly scratches the print and the first layer is sometimes very rough and unclean.
However, this does not affect the entire print area, but rather the corners and especially the bottom left.
The printer was completely reassembled using a square and a spirit level on a flat surface and everything should now fit correctly.
I have calibrated several times. Belt tension and roller tension is also correct.
The bed-mesh is applied but does not match the paper test. There are sometimes massive differences.
After several layers, the nozzle simply tears the print off the print bed.
The printer has the latest firmware and I use the Sovol Cura version from the USB stick.
I would be very grateful for help, I don’t know what to do next.
