i have printed cylinder with a hole inside to used it as a measuring jig. This is the first time after 7-8 litters of clear printing that I get this kind of failure.
I’ve printed the following on the finest setting of the print (0.25).
And this is what the printer did:
The spaces between the parts was filled by the layer half a thick of the support base. The holes in the middle of the parts that is through the entire part was not printed (3mm hole) and the parts are smeared. They supposed to be rounded.
