The bottom surface of my prints has become consistently coarse with lines that are evident to sight and touch. These are ‘fails’ in my book as I cannot pass such prints on to clients. It appears that the z height is slightly too high - but this should be automated so I’m unsure.
Old models that once worked now consistently fail in this manner.
Does anyone have any idea what may be happening or what I can try next? I’m out of ideas and would be very grateful for yours.
Machine:
- P1S
- Firmware tried: current and current-1
- High temp smooth plate
- 0.4 nozzle
What have I done?
- Tried multiple rolls of ASA and PLA
- Cleaned print bed with soap and hot water (standard practice)
- Performed cold pulls (standard practice)
- Changed out my nozzle
- Ran calibration between firmware changes and nozzle changes
- Tried old, previously successful prints (now fail)
- Created primatives in Bambu Studio for testing (fail)
- Tried classic and arachne walls
- Ran flow dynamics and flow rate calibration
