TAZ Workhorse is suddenly unable to extrude PLA. There is a strong smell of burning
PLA during heating and when it prints the PLA is barely coming out. An alarm went off and I stopped the print. This happened three times. I tried turning on and off/unplug, did a filament change, recalibrated, cleaned nozzle and bed (the PLA was very adhered to the bed). During filament change the PLA came out just fine. Does this sound like a clogged nozzle? Wonder about the burning PLA smell. Pics attached. PLA is Polylite True Black. Thank you.
TRUE BLACK. Thank you.
