I am currently a new proud owner of an UP300 and so far I have been having mixed success.
The printer is fantastic and when it works, it works. But the slicer software is letting the side down. I would love to print straight onto the bed but for some reason (with no supports ticked) it wants to put a layer or 2 between the part and the print bed. I have tried to move the part to the bed level and alter the supports so there is none. However when I go to use the slicer an error pops up.
If anyone could point me in the direction on the answer to be able to print straight onto the bed without supports and a raft, it would greatly appreciated.
