@cadetc thanks, I forgot to update the version number text. The time (14:00) means you have the correct binary. Are the temperature readings OK?

[CadetC]

@dc42
yes -temp OK

[dc42]

Thanks. Please can you both try file Duet3Firmware_TOOL1LC-34b2+2.bin from https://www.dropbox.com/sh/heg82sqvhpqb670/AAARGaD-zLptgnHj-PiqiwQBa?dl=0.

PS - I've just updated that file because the version text didn't update.

[Sotidii]

@dc42
OK!

Thanks to both of you. It appears that this bug has gone away as mysteriously as it appeared.

@dc42
there is definitely a difference between firmware 3.4b2 and 3.4b2+2
below is a screen with temperature reading for 3.4b2 and below for 3.4b2+2 -

comparison made just now

Thanks

Hi all,

I updated my printer after vacation and noticed the same issue.
I have upped the LC1 to 3.4.0beta2+2 and readings are back within expected range.

No recalibration done yet.

(I was not sure if there was a toolboard v1 reported or tested with the issue.)
