Right, it's time to get my #Creality #CR10v3 working again. All help gratefully received.

The problem is this:-

I added a BLTouch to enable #AutoBedLevelling. I flashed the firmware with the official Creality firmware and disconnected the end stop on the Z axis.

Now the printer shows that it is BLTouch enabled on the startup screen. It tries to auto bed level, but doesn't recognise when the BLTouch is activated by hitting the bed. It just keeps going down and I have to turn it off. TBC...

Some more progress from upgrading the fans inside the #Creality #CR10v3 control box by replacing them with more silent 12V variants. Only the last fan on the back has to be done, everything prepared since today. Noise level seems way reduced even now with one fan to go. 👍

Upgrading the fans of my #Creality #CR10V3 control box with silent fans, mostly going from 1x24V to 2x12V so that air flow should still be fine.

Previously in 3dPrint Odyssey....

I completed installation of the #SpritePro extruder on the #CR-10v3 #Creality chassis.
Inevitable fallout made me replace faulty nozzle thermistor, made a cable bypass, move Y-axis endstop, replace inner fans with the silent ones and...

Today's challenge is the #hotbed indicator showing flat 144*C, real temperature notwithstanding.
I checked the hotbed #thermistor circuit and it gives ~104 kOhm(?) all the way down to the mainboard (#Creality 2.5.2. #ATMega).

The only reasonable conclusion is that it is the analog port problem. If it is broken, I probably have no choice but to replace the mainboard - unless...

My clever monkey brain sees a spare analog port on the board (the one marked "Thermistor 2" below).

Would it be possible to reassign it for the hotbed thermistor? I assume it may need a recompilation of the firmware, but what the heck: I can do it if I have to, opposite to buying a new mainboard for another 120 EUR I do not have...
