J. Troubleshooting
1 Nozzle seems blocked:
First check and make sure the extruder motor is rotating and pulling filament and that
temperatures are right. If the extruder motor is working and the temperature is correct
you may have a blocked extruder. See below.
2 Software prompts timeout, no response while operating:
Please close the software, restart the printer, then reconnect to PC printing.
3 Extruder blocked with filament:
Please turn off the printer, remove the four screws on the extruder cooling block,
remove the fan and remove the extruder, then, using a pair of pliers to hold the
extruder restart the printer and heat up the extruder to the melting point of the
filament, use tweezers to remove the residual plastic filament. If this doesn’t work,
remove the nozzle and use tweezers to pull the blockage down. If the blockage is in
the nozzle it is usually simple enough just to heat the nozzle with a heat gun and the
blockage will ooze out.
4 X/Y/Z axis has irregular stripes on the finished object:
Check that the belts are tight, that the X/Y motors move freely and the limit switch is
not being obstructed. If all these factors seem ok it may be a slider setting problem in
the file.
6 Objects are warping or non-sticking to the platform while printing:
Check whether the distance between the nozzle and platform is too big, or change
the tape on the glass.
7 Printing from SD card doesn’t start when connected via USB cable:
Turn off printer, disconnect USB, turn printer on again and then press the function
button, which should then turn blue and start printing.
