Not for each new roll of filament, but I am relatively new (less than 1 month) and with the same roll I have some prints failing. Mostly because they detatch from the bed (Material is PETG, on an Ender 3 Max Neo). I've tried a lot of things already:
- Different nozzle temps
- Z axis offset calibration
- Cleaning the print-bed
- Leveling the print-bed (including the screws and the A4 paper trick)
- Heated bed vs. non-heated
- Printer placed in an enclosure to prevent drafts
So far it seems to go alright, but I still get detatching prints occasionally, or deforming mid-print. It's kind of frustrating :(
Oh thanks for pointing out the bed springs! That does sound like something that can be happening, since they seem to slowly 'unwind' causing the bed to lower. I'll add some washers; thanks for the tip!
