Here you find a list of common problems which can occur during the print.

Contents


Object bend up from the heatbead (ABS)

I had this problem under the following environment:

  • Printer: reprap prusa i3
  • Extrude: mgs
  • Nozzle: jhead 0.5mm
  • Filament: abs black 3mm

Solution 1

After many try an errors I found the following solution:

My printer said it has 100°C on the heat bed but it were only 80°C. I had to replace the thermistor. After this I the ABS sticks much better. I set the temperature to 105°C, more than that temperature consume more time (about 20 minutes and longer). It is very important to calibrate the heat bed levelling correct and adjust the nozzle heat bed distance.

Layers broken (ABS)

I had this problem under the following environment:

  • Printer: reprap prusa i3
  • Extrude: mgs
  • Nozzle: jhead 0.5mm
  • Filament: abs black 3mm

Solution 1

  • I have to turn off the fan's. The layer breaks because the object cools off too fast

Bad first layer (ABS)

I had this problem under the following environment:

  • Printer: reprap prusa i3
  • Extrude: mgs
  • Nozzle: jhead 0.5mm
  • Filament: abs black 3mm
  • Temperature: 230°C

Solution

Increase the nozzle heat bed distance

Bad top infill (PLA)

I had this problem under the following environment:

  • Printer: reprap prusa i3
  • Extrude: mgs
  • Nozzle: jhead 0.5mm
  • Filament: pla green 3mm
  • Temperature: 170°C

Solution

Reduce the perimeter shell to 1

Object bend up on the outer perimeters (ABS)

I had this problem under the following environment:

  • Printer: reprap prusa i3
  • Extrude: mgs
  • Nozzle: jhead 0.35mm
  • Filament: abs white 3mm

How it looks during fail:

Solution

I had to increase the fan speed because the temperature of the print was to high.

The surface has bulges (PLA)

I had this problem under the following environment:

  • Printer: reprap prusa i3
  • Extrude: mgs
  • Nozzle: jhead 0.35mm
  • Filament: abs white 3mm

Solution

TODO (Testing: reduce the external perimeter speed)
