The Printer Does Not Heat Michał Leśniak October 27, 2018 20:25 Follow If neither extruder nor bed does not preheat despite using preheat functions, it may mean that a fuse in the electronics board is burned. In such case, please contact our Support Team at firstname.lastname@example.org. Remember to send them a serial number of your printer. Do not try to repair the printer by yourself!
