Paint On Fail
Relatively new to Prusa Slicer (5 mo.) and finally decided to try paint on supports. First two prints failed miserably. The last one produced something I had never seen before--the supports broke off in mid-print (see attached photo). Sorry I didn't save the paint settings in the project file but I basically painted the elbows and the underside of the nose(s). Since I have almost no experience with paint-on supports, I am not sure what I am doing wrong.
Can somebody help me with diagnosis / solution?
RE:
Not sure what's happening, but I use paint on supports almost exclusively. I've never seen anything like what you are seeing. All they do is allow you to select where supports go, nothing else is different. The fact supports are failing implies some other setting, like the support/part contact distances are too large? You might try organic supports to keep the support base attachment only on the print surface (don't build supports from the part).
RE: Paint On Fail
Still not sure what happened but I redid the supports being very careful to get all the strategic spots. I also tried to make sure that I had solid areas with the paint cues so I didn't have any small threads in the supports. The print output was very good. I used traditional supports. When I used organic supports earlier I had a hard time removing them. I ended up throwing away the print.
RE: Paint On Fail
I liked the model enough, and am playing with a new C1, I tried printing it. Base organic supports failed: too fine a feature and the C1 mangles it every time (I've had this happen on many different models now). Increasing the branch diameter and adding another paint patch to force a new tree, the print finished. I agree the organic supports can go places the vertical supports can't reach, making removal a bit tedious sometimes, but that also is a feature. I've also struggled with normal supports doing weird unexpected things, like building inside hollows where the support is larger than the only access hole... lol.
Happy to hear you got a finished part.
