After initial problems with no adhesion I leveled the bed a couple of tiems. My method is to pinch the paper between the bed and the nozzle to grab and feel a strong friction taking out the paper-sheet. Then in PrusaSlicer I set the Z-offset to 0.2mm and it started printing fine-ish (pic.1, 2, 3 and 4). I made some printer vibrations dampener and figures (around 14 prints ~1,5h each). Next I printed a PS4 Slim Stand (pic.5) and separations between layers appeared. I increased a bit the temp and run a second piece of the PS4 stand and a dissaster appeared (pic.6) and since then the adhesion to the bed is gone. One in 5 attempts with some glue the filament sticked to the bed, but the next layers have a lot of missplacements and eventually filament sticked arround the nozzle and a destroyed print. The problems I noticed since the beginning: 1. adhesion is not great. The nozzle clean line is 80% of attempts dragged with the nozzle to the center of the bed when the brim starts printing. And gets curved just outside the hotend. 2. a 1-2mm of filament is always outside the nozzle (overextrusion?). I usually clean it with my fingers - wrong? 3. the printer has a glass bed but I would like to try using the magnetic Ender sheet. The glass is glued to the printer (pic.7)? Can I place the magnetic sheet on the glass? Should I then set Z-offset on the printer settings to avoid nozzle coliding with the bed? 4. On retraction, the extruder makes a loud click and sometimes a squeak. Is it normal? 5. I had a hard time to put the filament in the tube of the extruder. Like it was missplaced and had to bend the tip of the filament. 6. I washed the magnetic sheet with dish-soap and I’ll try my chances today. 7. The PLA is black, stock Ender3 filament which I suppose is not best quality, but should be sufficient for start… Im also considering moisture in filament as I don’t have a sperate room for my printer. Pic.6 - can it be caused by moisture? 8. After what happender on Pic.6 the extrusion was really poor which I think was due to clogged nozzle. After heating to 240C, pulling out the filament, needle-cleaning the nozzle the amount of filament extruded returned to what it was at start. Some settings: - 205C and 60C for first layer - 200C and 55*C for the rest - retraction ON - no Z-hop (I’ll try to avoid it for now, since it didn’t help) - brim on - 0,2 layer height - first layer speed 20mm/s, rest ~40mm/s Any advice welcome and I’ll provide more info if You have any questions.
