Looking for some advice. I’ve had some good prints so far and been getting some really smooth surfaces with 0.2 mm. I have been managing to tune bit by bit and I’m pretty sure I have good values for speed and temps.
This print however seemed to have all the problems together.
The problems are
- The occasional blotches on an otherwise smooth side.
- The longer strands coming out of the side.
- The slippage in the X axis (and to a lesser extent Y) at higher Z heights.
Some data:
- RepRapPro Huxley
- PLA
- 180 C
- 0.2 mm layers
Slic3r and OctoPi
Any advice and comments greatly appreciated.
Are you using retraction? Also, lot of my prints looked like this until I realized the big gear on my hobbed bolt was loose where the nut locks it in place meaning that when it to retracted the gear moved but the play caused the hobbed bolt not to move. I replaced the gear with a new one and all of my ooze problems went away. For skipped steps you may need to tune your stepper drivers a little more.
@Ryan_Hescock_Stanos thanks for the info. Do you mean the gear on the extruder motor end of the bowden?
@Ryan_Hescock_Stanos Great tip with the extruder gear. It turned out that it was slightly loose, but enough to have a little kick every time it retracted. I also adjusted the retraction settings in slic3r and it’s mainly gone.
Oddly the X/Y problems have gone too, but I will investigate tuning anyway.
