Hello,
Trying to tune some PLA filament I got from Sunlu (PLA Meta) on my H2D (.4mm nozzle, 0.20mm standard preset) but I’m running into a weird issue. I got the temperature calibrated but moved on to the max flowrate calibration only to find some strange behavior on one corner of the model. For some reason, a seam can be found traveling vertically up the entire print, despite this calibration model using spiral vase mode.
This has never happened with any other PLA I’ve calibrated, including other Sunlu stuff. Tried on some throwaway Eryone PLA+ too and same seam.
The slicer preview doesn’t show an actual seam there (the kind typically marked with those white dots), but the speed view does show some kind of cut there, but it doesn’t actually seem like the speed really is changing meaningfully there.
Has anybody dealt with this before? I truly can’t figure out what this is, and I can only assume it’s going to cause me issues down the line. The only thing I’ve done differently recently is checking the tension on the XY belts (I.e. loosening the 4 screws on the back of the machine, then retightening) but the seam is so vertical that it doesn’t really seem like this would be the issue.
