@dc42 said in Duet2 wifi + Duex5 board thermistor issue:

version

yeah, I saw the beta version, I just went with the latest stable release. I'll have to remember that for when I upgrade.

@szalek Awesome, Thank you so much!

@phaedrux firmware is 3.3 (2021-06-15)

I recently got a Duet2 Wifi and Duex5 expansion board for use with the e3d tool changer, but the two thermistors on the Deux expansion board are showing the wrong temp readings. The thermistors on the Duet2 show room temp(22C), but the ones on the Duex show 7C. swapping thermistor connections shows correct temperatures on any connection to the Duet2. Am I missing something here? Should I start a warranty claim or something?
