It might be that the ENDER3 has different offsets and might need adjustment on those values or maybe use a different mount, not sure. But if the auto-leveling runs before print it clearly gets bed leveling data, there is something else disturbing that, either some offsets or maybe problems with the temperature & the material not sticking.

I don't see any reason why not.

I don't think the position switch is your problem. Re-check your wiring, unfortunately I don't know what error 500 means.

Thank you for the heads-up!

thank you for following me.

yup the thermometer design from Hakko stayed pretty much the same and you can find clones like mine for very little on ebay,

That's an output with the signal coming from the bluetooth module.

Led was connected to the pads of the already existing LED. Any 3mm red/green led should work, the current limiting resistor is already in place.

I wouldn't recommend doing that. We are talking about 2.4GHz here. A simple wire soldered to the antenna trace will likely affect the tuned circuit and cause worse reception.

thank you!

thank you for the suggestion!
