I’ve been having a problem with my qidi tech 1 printer lately. Basically what happens is that for the first 20 minutes of my 3D print it prints perfectly with no problems. Then, the Extruder begins to stop at random points for about 4 seconds and leaves a big zit of filament. It will then proceed to print for 6 more seconds and stop for 4 more continuously. It leaves behind huge bumps on my product. The weird thing is that when I go to my computer and move the cursor around a little, it begins printing perfect for the next 20 mins again. Just wondering if anyone know how to help. Any help would be appreciated. Thanks!
