You have a 3 wire or 4 wire mossfet?
I'm not sure. See picture of the mosfet here: https://imgur.com/a/vhDvJUY
On your hot bed can you reverse the wires? And try to warm it up again
refer?
Reverse sorry..... online shows the board has the + and - backwards and it shouldn’t matter since the bed has no polarity since it’s just a resistor but some say switching it has worked
Switched it, same result. I even switched one of the thermistor. Same result
On you printer.cfg try changing your hotbed sensor pin to .23 instead of .25 let me know what happens
If nothing move your hotbed thermsistor to th1 with the sensor pin still .23 and if nothing go back to normal...starting to sound like a bad board out of ideas
yeah I tried that. Looks like there is a portion of the board that is dead. Not all of it but maybe something was missed in manufacture. I will try to get it exchanged
Thanks for your help!
No problem and good luck
Bad board. Closing issue
Hi, swtched from the Ender 3 board to SKR 1.4 with TMC2209 and BLTouch.
I managed to get the printer back on, xyz move but the BLTouch does not work and I don't have temp nor can I heat the bed or the extruder.
