I am a new 3d printer user. I have a stock Taz 3 with a budasnozzle 2.0 . I struggled some to level the bed but eventually got it right. I printed my test octopus using PLA (Jet 3 MM natural) and all went well. During my second print the extruder clogged. I was out of time so I turned off the unit. I wish I had tried to extract the filament right then but I did not. Much later I tried opening the feeder and pulling the filament out with the hot end at temp but it was well stuck. The hobbed bolt had worn a nice notch as expected. Manually feeding and pulling back the filament were not working. I took the hot end off the feed mechanism and tried to pull out the filament and tried increasing the temp a little at a time without luck. The filament eventually broke off level with the aluminum plate. I tried forcing fresh filament in, no luck.
I assume I have to disassemble the nozzle to clean it out but I cannot find any guidance on how to do it. I am open to suggestions on how to proceed and if there is a link that might help, please let me know.
My first thought is to unscrew the nozzle from the hot end and see what I find. I assumed I could probably heat it up and feed new filament through it with the nozzle off. Wille the nozzle come off the extruder while both are cold and it is in this clogged state? Should I heat it up? Past 180c?
I red about people soaking ABS clogged extruder parts in acetone. I see no equivalent solvent for PLA. Does acetone work on PLA like it does on ABS?
After much reading I ordered some ABS from Lulzbot. I thought PLA was the more noob friendly filament type but it appears the taz 3 is optimized for ABS as delivered. I may try the “PLA mod fan” approach Lulzbot support sent me if I ever get this working again to print the duct and the PLA reel sitting there makes me adventurous (or cheap). I will measure it and set the diameter in the SW.
