I recently treated myself to a black Alu/PEI bed from Clever3D, and finally had a chance to try some prints with it, however so far my experience has been deeply disappointing. After installing it I levelled the bed and gave it a quick wipe with isopropyl alchohol to remove any fingerprints, then tried a print in Edge. I'm printing at 0.2 layer height, 240º nozzle temp, and I've tried various bed temperatures between 80 and 95º (I would print Edge at 240º/80º on glass, reducing to 220º/70º). So far absolutely nothing sticks at all. I don't mean it warps a bit, it's not even close to sticking, either the nozzle just drags the filament around or at best it gets one perimeter down but it's so loosely adhered the nozzle just pull sit right up again when it starts the next one. I've tweaked Z height to the point where it's so close to the bed it stops extruding, but it still just will not stick at all. I've given it a long soak at temperature before printing to make absolutely sure it's up to the right temperature. This seems very contrary to other people's positive reports, so I'm wondering if I'm either using completely the wrong temps, there's some other preparation needed to a brand new bed, or my bed is just defective in some way. Can anyone who's printed Edge on this bed confirm I'm in at least vaguely the right ball park bed temperature wise? Any other suggestions? This bed wasn't exactly cheap so I'm pretty gutted at the moment. I'm giving up with Edge for the moment and trying some other filaments to see if I have any more luck with any of them.
