Hello and thank you for choosing the Leapfrog Creatr for your printing needs.
The solution applies to the: Lepfrog Creatr Single and Dual extruder and also the Creatr XL.
If the hot ends on your Leapfrog Creatr printer do not heat up please make sure to check the following:
1. First check the heat cartridge connectors above the printhead:
2. Now connect the PC to the printer and check if the thermistors are reading the ambient room temperature before you try and heat up the hot ends and the bed ( if one thermistor is not working it will read a 0 degree ambient room temperature);
3. Next remove the side panels of the printer and the interior cover plate to expose the electronic board;
4. Once the electronic board is exposed heat up both extruders and check on the motherboard that there are two Red LED lights that turn on; See the picture below as a reference:
If one of the LED lights does not turn on it means the board malfunctioned and is no longer reading the extruder and has to be replaced; For this we ask you to open a ticket and contact our Technical Support Department where a support agent will help you order the replacement motherboard.
A non functioning thermistor will lead to a instant M999 error and the same goes for a board which is no longer able to command one of the extruders.
Thank you for reading the solution and, for any other issues, please do not hesitate to contact our Leapfrog Support Team.
We wish you happy printing!
