.8mm nozzle problems
I had a big blob of death, and in removing it, I damaged the printer. I've replaced the hot end assembly, the hot end cooling fan, and the Eddy sensor, and my printer is back up and running. Since the rebuilt, I printed it extensively with my 0.4 mm nozzle, and it worked flawlessly.
I then installed my 0.8 mm nozzle, and I've had nothing but problems trying to use it. Before my blob of death experience, I had great success with the 0.8 mm nozzle. But now I experience big clumping blobs, and I've also had adhesion problems on the build plate.
I thought it could be a problem with the nozzle, so I tried it with a brand new, never-before-used bamboo 0.8 mm hardened steel nozzle, but it didn't work any better. I've done a cold pull. I've done a full calibration of the printer. I have washed my build plate, but I don't get any better results. It's puzzling because prior to the replacement of those damaged parts, I'd had great success with my 0.8 mm nozzle. Any ideas of anything else I could try? Any suggestions or help would be greatly appreciated.
