Bad print Image

Hallo there,

The x axis was loosen from the Motor. I fixed it, and calibrated with the assembly instruction. Now i have a bad printing. Is the space between bed and nozzle wrong?

The bed is heated at 50°c.

I habe the printer since 3 days, it printed well unter the motor was loosen.

And Sugestions?

Hello !
Yes it seems that the nozzle <> bed distance needs to be reviewed (adjust the screw that triggers the endstop Z during home)

To get an idea of a good first layer (Sorry I don’t have it in English)

Edit : Also, how do you clean/degrease your tray? because the slightest trace of finger can interfere with adhesion.
