I see a lot of people claim they tune/calibrate their printer any time they use a new spool of filament. But does anyone actually do this? It feels like a waste of time when filament is so consistent, even between brands. I can understand doing it for specialty rolls, but for basic pla? Seems unnecessary
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!
I did this more as a temporary fix. There are lots of sellers of stiffer spring sets or silicone spacers for Creality printers online. There are also several models on thingiverse for printing your own spacers.
