I have a KE and my bed looks like a fabric, right?
Do you still clean it like mentioned above?
It should be a PEI bed, you clean it with Dawn/Fairy dish washing liquid, dry it with a paper towel or let it airdry, then wipe it down with IPA alcohol. I wash mine every 10 or so prints and wipe with IPA every print. Finger grease is a nemesis. I try to handle my print plates like a vinyl LP.
TIGHTEN LEAD SCREW HOLDER BOLTS, they come pretty loose which isn’t a problem at first as the printers come freshly oiled and when everything is clean and new everything moves a bit better. BUT, after collecting a little bit of dust on that fresh oil, after saying 2 weeks, things get less smooth ya know. The lead screw holder bolts, or the 4 bolts in total that help hold the 2 lead screws in place, come looooose, tighten them but make sure to do it evenly so the lead screw holder is even to the ground. Then check if there is any play in the lead screws when you push them UP and DOWN, if there is, you need to reposition the pulley at the top so it pushes the screw downwards. To do this simply loosen the pulley, push the pulley upwards, and the lead screw down, then tighten. There should be NO play afterwards.
