It could be the heating block. If your heating block is not insulated well the heat will travel up. If the heat travels up that means the plastic in the motor gets a little mushy. If this happens your motor will usually just barely be able to push the filament and might make it come out stringy or n…

try to tighten the extruder gear. I have a similar problem and this helped, although it still happens from time to time. I noticed the gear eats into the filament and then stops to push it through. It could also be that the gear shifted on the stepper motor shaft and is not aligned properly anymore.…

Get a pair of vernier calipers and measure the filament diameter if it’s any greater than 1.9mm then it will jam in the extruder. We had this problem when we found a cheap supplier of filament. hope this helps

Yea I had this issue with PLA filament. Pla is much dryer than ABS. So I had to print a dust collector and in there I put a sponge with olive oil. It will last quite a while until you have to reoil it. You aren’t soaking the sponge in oil either. It doesn’t need much.

I ended up replacing the entire assembly on mine, and a bunch of other stuff too. Last thing I did was replace the cables to the end-stops which went bad.

What material are you using? Have you check the diameter of the filament?

also get a new nose head i have had mine for 3/4 yers now

Try a different (newer ) spool of filament. It may have absorbed water. Is it only with one extruder or both? I have had this issue before on one extruder. The temp readouts looked okay but I decided to swap left and right heaters anyway. The problem followed the heater. Bought a new heater and the …

I had a similar problem with a rep2 and finally it was the extruded fan not working at full speed, try replacing the fan, they are cheap and you don’t have anything to loose. good luck

Could you check the filament is still correct size? I have had filament printing fine, and then dia is slightly larger as i used the reel. If you just extrude well above build platform does it extrude perfectly? Straight out, not to one side? Finally, have you recently cleaned the drive gear the pus…

I run a Rep1 Dual and I would agree with funkshin. My prints that lost material part way through were all due to the filament getting snagged or too much friction in the feed line. A little oil helps - also make sure your spindles can turn freely.

Well if you have been using this for 2 years then it would be time to replace the hotend and peek tubing if it is not an all metal hot end I can generally get about 4 months from a tip without quality issues the peek tubing tends to get worn over time and also when you replace them you must tighten …

I had the same issue and found adding a bit of lubricant to the tip of a piece of filament before loading was helpful. RE:

is the fan still working properly ? if its to weak than the nozzle will get blocked. at least that was my experience. once i put new fans everything was back to normal
