I've had my Ender 3 Pro for a few months, and it's been working great. Then, after a failed print (the STL had extra seams, causing the print to get mangled), I've started having issues that I have attributed to under-extrusion.
As evidenced by the below image, some lines in each layer are missing. The gaps align throughout the print, but not between prints (the two squares are identical G-code). This happens in every layer, with a different pattern in each. It also causes some perimeters to not adhere to the previous layer at all.
The extra strands in the right print are present because I ripped off the infill layer that printed on top before I aborted the print.
I first assumed I needed to calibrate my extruder. It turns out I did (93 had to be changed to 150 steps/mm). However, that did not fix the issue.
Some things I've tried:
- Calibrate the extruder
- Check nozzle size and filament size in Slic3r
- Level the bed (I had to place a post-it note under the centre of the flexible magnetic build surface to make up for a warped bed)
- Clean my nozzle and hotend (I fully dismantled the hotend)
- Replace my nozzle
- Increase printing temperature
Is there anything else I might try to get this fixed?
Specs for Reference:
- Ender 3 Pro
- 0.4 mm Brass Nozzle
- 205 °C Hotend
- 60 °C Bed
- 150 Steps/mm for Extruder
If you need any more information, just comment and I'll do my best to supply it.
Please note that I am not open to suggestions to replace my printer. I'd rather fix the one I have.
