Wavy mystery, unacceptable quality
Hello, I got my kit a week ago and built the printer over the weekend. However, the surface quality is sub-optimal and not normal, as I've been told. There are waves. I'll add some pictures to show the issue:
The first print looked comical even, compared to my old Ender 3 V2. The spacing of the pattern is 2mm, which leads me to believe the issue has something to do with the motion system (belts?). I have so far:
- recalibrated belt tension, input shaping and phase stepping
- set speeds to use only the official presets, structural and balanced
- tried gyroid, cubic and grid infill
- loosened gantry on both sides and retightened
- reset the printer and redone calibrations, without calibrating for input shaping or phase stepping
- tightened belts, loosened belts, tightened belts...
- loosened linear rail and retightened
- removed extruder gears, reinstalled and recalibrated extruder
- talked with support
The quality with structural profile is barely acceptable. I thought these steps had fixed the issue and tried reprinting my part using balanced preset. The print started to look wavy again so I stopped it. Interestingly, the rear left corner had a few layers where the waves did not appear:
But that is the only wave free section I've gotten from this printer. Support asked me to print a cube, well I printed this thing:
It seems to me that sections printed slower have less waviness going on. The printer also has some massive resonance. I linked this video to support chat too, but they didn't say a word about it. Is it normal?
If you have any suggestion, please do share them.
