I had a problem with a print whereby it wouldn’t stick to the bed, even when using a brim or a raft.
In Repetier there is a gap at the bottom and with Prusa it brings up the error “no extrusions on the first layer”.
I eventually identified the problem to be related to the very fine edge of the bevel with the model.
The solution was to invert the model so I am printing the other flat end on the bed with the bevel at the top. I wanted to share this video in case it helped others.
I also mentioned linking to the model I am printing which is the Flame Gun from Logan’s Run: https://www.thingiverse.com/thing:503407
