SKR 1.4 with TMC2209 and BLTouch #2772

Closed Xenomorphdelombre closed 4 years ago

Xenomorphdelombre commented 4 years ago

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.

Attached is Klippy.log

You have a 3 wire or 4 wire mossfet?

Xenomorphdelombre commented 4 years ago

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

Xenomorphdelombre commented 4 years ago

refer?

davidja92 commented 4 years ago

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

Xenomorphdelombre commented 4 years ago

Switched it, same result. I even switched one of the thermistor. Same result

davidja92 commented 4 years ago

On you printer.cfg try changing your hotbed sensor pin to .23 instead of .25 let me know what happens

davidja92 commented 4 years ago

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

Xenomorphdelombre commented 4 years ago

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!

davidja92 commented 4 years ago

No problem and good luck

Xenomorphdelombre commented 4 years ago

Bad board. Closing issue
