appropriate temperature in the hotend during material loading and the printing process. Also, the heater transfers the signal required for the printer to complete the platform calibration. Therefore, if the extruder is overheating or the heating is insufficient, or if your prints have blisters and hanging strands on their surface, the heater and thermocouple may be faulty and require replacement. Also, the extruder heating problems are indicated by the firmware messages: Error #010 Extruder heating error, Error #011 Extruder temperature is too high, and Error #013 Unexpected extruder temperature drop. Sometimes, if you are unable to finish platform calibration or if the nozzle hits the platform during the pre-print calibration, it may be necessary to replace the heater and thermocouple. Before replacing the heater and thermocouple, make sure that they are properly installed in the hotend. If you have the heater&thermocouple v1, you also have to replace the hotend and the extruder PCB. The following manual shows the M200 repair work. For the M300, these procedures are the same. page 3 / 23

If the material is loaded into the extruder, unload the material using the “Material” -> “Unload the material” option in the menu. page 4 / 23

Turn off the printer and unplug the power cable. Wait until the printer – especially the hotend – cools down completely. page 5 / 23

Detach the material guide from the extruder cover. Next, separate the guide from the extruder cable. page 6 / 23

Detach the extruder upper printed cover and unplug the extruder cable. page 7 / 23

hotend from the extruder. page 8 / 23

Hotend) With a 1.5mm Allen key loosen the two screws that secure the heater and thermocouple in the hotend. Then remove the heater and thermocouple. page 9 / 23

Unplug all the cables from the extruder PCB. page 10 / 23

Unscrew the two screws that secure the extruder PCB using a 2mm Allen key. Remove the PCB from the extruder. page 11 / 23

Remove the extruder lower printed cover. page 12 / 23

Extruder) Remove the heater and thermocouple from the extruder block and from the heat shrink tubing. Unplug the cables from the extruder PCB. page 13 / 23

Extruder) Plug the heater and thermocouple cables into the extruder PCB. Put them through the heat shrink tubing and inside the extruder’s block. page 14 / 23

Attach the extruder lower printed cover to the extruder. page 15 / 23

Place the extruder PCB in its place and secure it with the two screws. page 16 / 23

Plug all the cables in. Remember to arrange the cables so that they don’t get damaged, e.g. by wrapping against each other. page 17 / 23

Hotend) Insert the heater and thermocouple into the hotend and firmly tighten the two screws that secure them (using a 1.5mm Allen key). Make sure that the screws don’t go through the insulation that covers the wires (this can happen if the heater goes too deep into the slot). page 18 / 23

correctly. This picture shows the heater pushed too far into the slot in the hotend. page 19 / 23

Plug the extruder cable in, and then attach the extruder upper cover to the lower cover. page 21 / 23

Attach the material guide to the extruder cover. Next, secure the guide to the extruder cable with the material guide clamps. page 22 / 23

Plug the power cable in. Powered by TCPDF (www.tcpdf.org) page 23 / 23
