I ordered a heater cartridge with new thermister, heater, heater block, Thoat pipe, heat sink, boden tube. Whole assembly except for the fans. These assemblu is due in Monday. If this doesnt work then the SKR 1.4 board going in. the firmware file on a micrSD card that came with printer is useless. I used same MicroSD card to transfer gcodes from computer to printer in the begining. Plus the stock board not having a bootloader < i dont want to have to purchase something else just to load firmeware.
