What causes prints to fail?
Over extrusion happens when your 3D printer pushes out too much plastic too fast, causing a jam in the end of the nozzle. This jam builds up more and more until the hotend stops extruding altogether, leaving your print unfinished.
Why does my print keep shifting?
Print speed can cause layer shifting because, if set higher than your stepper motors can handle, the motors may move less than they’re told to. Also, you should make sure that your stepper motors are performing as expected and keeping up with the demand for motion (they often make a clicking noise when failing).
What could be causing my Y axis to slip?
From what I’ve experienced, there could be three potential reasons. Your belt (s) could be loose. Simply loosen your Y-Axis motor and pull the motor until the belt is slightly more than taught (it will relax into a taught position). Then, tighten the motor securely in its place.
Why does my 3D printer keep losing pulleys?
As you know a 3D printer is a machine that works with the combination of different parts and these parts can require maintenance at some spot. Just like the belts, pulleys can also lose with the passage of time. Pulleys are directly connected to the belts because pulleys make the belt move.
How to troubleshoot layer shifting in 3D printed models?
Turn the motor pulley manually to check if there is resistance. The pulley should rotate smoothly. If the pulley rotates with resistance, move on to the next step. Disassemble the other axis motor (which is probably functional) and check its pulley.
Why does my printer not do positional offset?
In my experience, the most common reason for positional offset during printing, is the motor skipping steps due to physical impact. Your stepper motors do not give positional feedback to your printer. So, if you forcefully move your motor during print, then the printer will not notice, and simply pretend it never happened.
