Thanks again Jules. Just one zip tie to solve another one of those little problems that I don't think about until it catches during a print. 3. The extruder cable continues to get yanked and torn by the beds upper right pin that holds the glass down and is getting close to tearing the internal wires...

To close the loop here, I contacted technical support.

It turned out that my extruder had gone all wonky on me and that I needed a new one. The new extruder is here and is working just great. I've been able to print a spare and I'm up and running once again.

Thank you MG Support!

I went back to my Rev. D user manual and it does say to run at 220. I changed my temp setting and ran a good looking 20mm calibration cube. I'm now trying to print a larger part of something. It's maybe 20 layers in and it's looking very nice. Maybe it was a combination of things that I tried at 220...

As soon as I changed to a different color PLA, the problem came back. I had previously printed fine with this spool and now it extrudes for a bit and then gets stuck. I just cleaned the extruder gear and I'm going to try again and see what happens. This is very frustrating as I need to be able to sw...

jtrue, The M2 isn't my first printer, but my first one involved a pretty big learning curve and it took me a while to get the hang of things. In addition to the advice given so far, I would suggest using one of print files included with the SD card from MakerGear. These have already been sliced, so ...

OK, I was still having a few problems with the extrusion, so I moved the temp way down to 195 and it works much better. I'm not sure if my new hot ends have the thermistor closer to where it needs to be, but it appears to be more accurate than the one that came with my Rev. D machine. I'm pretty sur...

Jules, you are amazing. It was indeed the tension. I'm down to 210 and it seems to be working well. I'll hunt for the answer a little harder next time.

Thank you, that is an incredibly useful post. I'll work on setting the tension correctly this morning.

Oddly enough I did a search for this problem, but didn't hit on this thread. My thread is awaiting approval by a mod, but it looks like this thread has it more or less covered. I've got the same problem, but I'm not seeing how the filament guide tube goes into the extruder head. I'm guessing that's ...

Up until recently I've been having great success with my M2. Lately I will get the printer up to temperature, extrude a little PLA and start the print. Very soon after the print starts, the flow stops and in order to get it to go again I have to manually push down on the filament. This happens even ...
