I am so fed up with this printer. Out of approximately 10 prints it might finish one. This is printer is not used at home, but in a lab, so I can't monitor it over night. 90% of the time the filament breaks (different kinds as well) because the motor skips. I have to slow the print wayyyyyyyy down, but even then it's hit or miss. Even basic objects, such as an octahedron, it fails on. Here is what I have done to for troubleshooting:
- Ensured proper temperature to prevent heat creep (this includes retraction settings as well)
- Ensured proper tension on the feeder
- Cleaned the entire printer from top to bottom, this includes disassembling the feeder and extrusion unit
- Checked the quality of the PLA (brittleness, etc.). We only use PLA in our lab. (PLA from Toner-Plastics.com)
- Tried every different way to ensure adhesion. I find the best results is with no heat on the build plate, blue painters tape, and to clean the tape with rubbing alcohol.
- I have completed about 2.3x10^{23552} atomic pulls
- I have done numerous torture tests to ensure the proper temperature, etc.. I found the best results are 205-210c
- I leveled my bed with numerous heights; .06, .07, .08, .09, .1, and .15mm. I found the best results are at .1mm. I have also done dynamic bed leveling as well.
- For each print I always check the mesh quality in NetFab, I go through with a fine tooth comb on Simplify3D to make sure everything is good as well.
I'm trying not to go Office Space on this printer, so any recommendations on what I am doing wrong would be much appreciated.
