Heater Not Heating ¶
Your device is cool to the touch, or filament does not extrude from the nozzle.
Caution: Device nozzle may be hot and may cause burns. Exercise caution when determining if device is cool.
Heater and Insulation Position is Too High ¶
Heater issues are most commonly caused by poor location of the heater and rubber insulation. If the elements are too high up the nozzle, the tip of the nozzle would be too cool. To fix this, reposition the heater to be near the tip of the nozzle.
Air Flow ¶
If the front cover of the print head is off, air from the environment (such as air conditioning or a breeze from an open window), may cool the nozzle. Put the cover back on the printer head, or if you have lost it, you may purchase a new one with request to M3D’s Technical Support.
Broken/Disconnected Heater Wires ¶
Unfortunately, the heating element might just be broken, or have disconnected wires. To confirm whether the heater is broken, load the filament into the machine as usual, and open the M3D Spooler application on your computer. At the bottom of the Spooler window, you should see the temperature rising. If the temperature doesn’t rise above 50 Celcius, the heater wires may be broken or disconnected. In this case, send a photo of the broken parts to firstname.lastname@example.org to begin the Return for Repair process.
Printer Drifting ¶
You have problems with incorrect placement of filament by the printer.
Print Bed is Low or Uneven ¶
Residue from previous incorrectly configured prints such as poor print bed calibration can cause the print nozzle to drift. Ensure no residue is present on print bed and properly configure the print bed offset in the software.
The friction between the movement bands and support rods is causing the nozzle to improperly print. This issue might also be caused by obstructions in the bands. Ensure nothing is blocking the tracks and carefully clean if required.
Uneven Printer Placement ¶
The printer nozzle can become stuck moving in one direction as a result of uneven placement of the printer on a surface or friction between the movement bands. Ensure that the unit is on a level surface, and that tracks aren't blocked by debris.
Printer Not Extruding Filament ¶
Filament is not coming out of the printer head.
Software Upgrade May Be Required ¶
Upgrade the software by downloading it from the M3D website.
Overheating Extruder (Print Head) ¶
The print head may be overheating, which causes the printer to have difficulty extruding material. This can then cause the filament to get pushed back up into the extruder gear. Remove wallE cover to access the extruder gear and clear the area of filament. This can also cause the fan to stop running while printing. Refer to the “fan” section.
Filament is Stuck in the Print Head ¶
If filament is stuck in the print head, remove it. Refer to the nozzle removal guide and follow the steps.
Fan Not Working Correctly ¶
Fan is not working while extruding.
Software Needs Updating ¶
If the fan is on full blast and very noisy, you may need to update the software to the latest version.
Wrong M-code Was Set for the Fan ¶
The actual M-code is not the correct one for your printer. A software upgrade will fix this problem.
Something Trapped in Blades ¶
If the fan is working at a slower speed than usual, there may be filament or a pinched wire trapped in the blades. Remove the obstruction.
Disconnected Fan Wires ¶
The fan wires could be disconnected. Check the wires to be sure they are connected. Make sure the fan is positioned correctly in the extruder housing. If it is too high, it will not rotate.
Broken Fan ¶
If your fan is broken, you will need to replace it. Follow the fan replacement guide on how to replace it.
Motion Control Error ¶
You have problems with the printer’s extrusion and motion controller chip.
Faulty Computer Connection ¶
Attempt to reconnect the USB cable from the printer to the computer. Restart the printer and ensure LED indicator light is on. Check to see if software continues to indicate the issue.
Broken Motion Control Sensor ¶
If the error indicating an issue with the motion control sensor reappears, follow the guide on how to replace it.
Print Not Sticking ¶
The print is either not sticking to the print bed (build surface) or not sticking to itself.
Print not sticking to print bed ¶
Uneven Bed Level ¶
If the print bed is not perfectly level, the print will not adhere properly to it. Turn the 3D printer off for 5 minutes. When you turn it back on, run the bed leveling again.
More Adhesive Needed ¶
Extra adhesive may be used to help keep the print from detaching from the print bed. Use blue painter’s tape or spray a little hairspray on the bed. You can also use a glue stick on it to help with adhesion.
Too Drafty ¶
If the print or the bed get too cool, the print can come loose. Block any drafts that might get to the print. Tape paper or plastic over the open sides.
Print not sticking to itself ¶
Temperature Too Low ¶
The inks and their different materials print at different temperatures. The temperature may need to be increased to keep the print from cooling too quickly and the layers from separating.
Obstruction in Extruder Nozzle ¶
Make sure the extruder nozzle is clean and free of debris. The layers will not fit together properly if the filament is not coming out correctly.
Printing Bed Not Level ¶
The first layer of print must be flat and level for the successive layers to adhere properly. Make sure the extruder nozzle is close to the bed and that the bed is level.
