This was a recent fail. It has happened a number of times, and I am wondering if this is a common thing. Burnt black and brown bits, failed print.
My theory: I am beginning to suspect it happens after I switch back to PLA after printing PETG at higher temps. If I have PETG in the nozzle, I have to heat to PETG temps but put PLA through behind it, and I think the PLA is getting burnt and stuck and finally comes out later, wrecking a PLA print. (???)
Any ideas? Thanks in advance! :)
I can't personally attest to this but I imagine this filament cleaner will benefit me as well when I switch between PETG/PLA.
