If your print gets interrupted and you get the message “Click to reheat” on the display, that means the printer has detected that the filament is not being fed trough at the expected rate.

The printer pauses the print job at hand and will wait for the user to check the issue. While it is waiting, the temperature of the extruder is set to a low temperature for safety (it may take a long time before someone checks the printer again).

If you click the blue button next to the display, the printer will first re-heat the extruder to the printing temperature again. After that, it allows you to manually feed some filament to get things working again. You can feed filament by turning the blue knob clockwise. If you click the button again, the printer will resume what it was doing.

Causes for this behaviour

  • Filament jam.
    A jam can occur when the filament gets tangled on the spool.
    Sometimes a bulge or kink in the filament causes a jam.
    In this case, make sure the cause of the jam is removed before resuming the print job.
  • Printer has run out of filament.
    Put a new spool of filament on the printer. Cut off the filament so that the end is flat. Feed the filament through the dust filter and the Teflon tube. Insert the filament into the print head.
    If the extruder is at its target temperature, feed through the new filament.
    The printer will then push the old filament through the extruder.
    When you are sure the new filament has properly entered the extruder, resume printing.
  • Very soft material (like Flex material).
    The filament can get squeezed so much by the clamping mechanism that the detector misjudges the amount of filament coming through.
    It may help to decrease the clamping range (see “Howto adjust filament clamping range”).
  • A clogged hot end that is preventing the filament being fed through.
  • See this article to find a solution.
  • The nozzle is too close to the bed or printed object.
    This can happen if the bed is not leveled right or the object is warping up.
    The filament cannot flow through the nozzle properly, causing the filament feeding mechanism to slip. Level the bed and make sure the first layer adheres really good to the heated bed.
  • clamping range that is too small. See this article.So not enough traction to pull the filament in the hot-end
  • Defective filament detection. Please diagnose it with this troubleshooting guide and gcode from the download section
