Temperature reading #5081

Closed tony21675 closed 2 years ago

tony21675 commented 2 years ago

I recently upgraded my hot end to a E3D-V6. Once I put it on and updated klipper and mainsail to the newest version both my hot end and bed quit sending accurate temperatures. Both are reading around 200c with no heat being applied. I have tried 3 different thermistors thinking one could be bad with no luck.

Most likely a wiring issue. Loose connector, broken cable, short circuit

tony21675 commented 2 years ago

Later today when I get a chance I will take it all apart and put it together peace by peace and see where it might be wrong.

tony21675 commented 2 years ago

Ok I disconnected both my hot end and bed (thermistor and power leads) still reading 180c plus. So I think my board is blown or something is wrong in my cfg file.

This file contains common pin mappings for the BIGTREETECH SKR V1.4

board. To use this config, the firmware should be compiled for the

LPC1768 or LPC1769(Turbo).

See docs/Config_Reference.md for a description of parameters.

BTT SKR1.4? If yes, you have a third temp port with pin P0.23

tony21675 commented 2 years ago

Yes it is giving false reading on both bed and hot end. Port 3 might be ok but port 1 and 2 both seem to be malfunctioning

tony21675 commented 2 years ago

BTT SKR1.4 correct
