Wipe Tower
Since I've had my MMU2 I haven't had much of a problem with printing. My multi-color objects come out very nicely. What I have had a problem with is the wipe towers. They always come out a huge, sticky mess. They are a big block of sticking up, broken pieces of material. This causes the fragments to melt all over the nozzle and heater block. They've even reached up and melted over the thermistor wires. This hasn't caused a problem for the actual object being printed, but I'd rather not have a huge mess of plastic fragments all over the bed, nozzle, and heat block. I almost have to take a vacuum to the heat bed after the print to keep them from ending up all over the room. Does anyone have a fix for this?
Re: Wipe Tower
This is a filament settings problem. You should be able to bridge easily across the ~10mm? distances in the wipe tower. I'd be guessing not hot enough.
Re: Wipe Tower
I had the same problem but fixed it by upping my temps by 5c now it bridges easily now
Re: Wipe Tower
had the same problem with PETG. I hope uping the temperatures will resolve this problem
