Oh no. I really would have left it alone. It was ok and the prints were pretty good just fine tuning. Fortunately it looks like it didn’t damage the bed itself. I would give the bed a good heat and gently see if you can smooth it any.
About the most you can get is about 110 for ABS. It is just a thought that it may settle down a little but I would be real careful also. Don’t want to make it worse! Right now it is near the edge so you should be able to print around it pretty good. I just was worried about calibration that the nozzle might catch it.
For a while I would run initially with my hand on the power switch ready to kill it if it acts up.
Aside from here this would be a good one for the Prusa forums. A lot of PEI gets torn up on new builds!! It happens so don’t despair.
I printed another white Benchy out of PLA. It looks underextruded. The gray Benchy out of PLA was one of my first prints when I first set up the printer. It was pretty much near perfect.
So I tried to calibrate the extruder…
I marked the filament 150mm above the extruder entry. Then manually extruded 100mm. Did this a few times to get the correct step per mm value.
The starting value was 162.30. After doing the measurements a few times and getting closer to the 100mm sweetpoint my steps per mm ended up at 175.64.
Ok, I never did a steps calibration on mine since everything is a known quantity from Prusa, board, firmware etc. I don’t know if it is needed if everything is stock but you can ask to see what people say. I never really hear about it. Extrusion is usually fine tuned via the extrusion multiplier.
You might rotate him on the bed so he faces a different direction and see if things change. It is hard to see in the pic what is really going on. What are the temps?
