My prints have had a number of issues with poor surface quality immediately above supports (and if I'm being honest, bridging too). I've had this problem since I first got the printer, but I generally haven't been printing things that require support or I've done post-processing to cover it up. Here's an example from the latest print I did:
And what it looked like on the bed:
Some details of this print:
0.2mm layer height
40mm/s print speed
215C first layer temp/210 after
60C bed temp
I've tried messing around with a few different settings like the ones detailed on Simplify3D's knowledge base
, but have generally only had mixed results. I've even tried printing a modified nozzle fan guide
(not this exact one since I can't find the one I made right now, but it's similar), although I've since removed it because it started warping a little.
My assumption is that this is probably some kind of cooling problem, though idk for sure. I'm considering trying to mount an extra fan like in this mod: https://www.thingiverse.com/thing:2342067
as my next step to see if that helps. It's worth noting that even though my print temp is 210 here I normally do 200 for other PLA - the stuff I printed the ocarina above with is eSun's PLA+ so it has some additional polyesters mixed in with it. The result is still the same with standard PLA unfortunately.
Is there anything else I try? I appreciate any suggestions
