M2 clogged nozzle?? Extrusion problem.
Posted: Fri Aug 14, 2015 2:01 pm
Printer is four months old, never had a problem. Printing PLA almost exclusivity did a small ABS print last week. Using stock temps in S3D, 215 for PLA, 235 for ABS. I have completed several large prints in PLA since running the ABS without issue, halfway through a good PLA print the nozzle seems to not be flowing properly and I got a very poor print, stringy and inconsistent, not solid- stopped the job and trashed it.
Originally thought it was a snag in the filament, checked it, tried again, now it's just printing garbage, stringy and inconsistent. Last night I printed PLA at 235 thinking the nozzle was clogged. PLA printed perfectly at 235, figured I had cleared the clog, shifted the bed, rotated the part and switched back to 215 - stringy and inconsistent.
I've attached a photo, the model in the back is PLA at 235, looks good, the model in front is PLA at 215. So is this a clog? Do I have to take the extruder apart to clear? Has this happened to anyone else? What's the procedure?
Thanks.
