Do i need to worry about my mmu3 melting inside an enclosure?
I have a prusa mk4 with the prusa original enclosure and am about to add a mmu 3. I've had issues with deformation at High Temp on my mk4 y axis belt clip and possibly my filiment idler arm. I am putting together a plan to replace parts near heat sources with ASA. Has anyone had issues with their MMU3 deforming inside of an enclosure at ASA or PC temps?
Thanks in advance for the help!

Thanks for posting the question. I have the same thought on my mind, as I am planning to purchase a Prusa Enclosure and do ABS prints with a MMU3.
My questions are:
- Do the printed parts somehow deform when the enclosure is getting warm after hours of printing?
- Does anybody experience negativ effects on the electronic parts?
- Does it help with ABS prints?
Thanks for your help
RE: Do i need to worry about my mmu3 melting inside an enclosure?
I think what happened to my belt y belt holder was that PETG is fine at the 40c chamber temp I was printing at, but the bed is a heat source so the holders were actually quite a bit higher. I noticed that prusa made a comment in the mmu3 manual about how the PETG idler had the same issue. They replaced it with what look like CFPC parts so my plan is to print replacement parts in CFPC for anything adjacent to a heat source and replace as needed. My MMU3 has been running for several weeks at this point and doesn't seem to get hot enough to be a concern, but I'd love to have people with higher chamber temp. Mmu3 experience weigh in. I really don't know what's best, especually after heavy use.
