[3.6.0-beta.2] issue: 1LC inconsistent temp reading

[Alex.cr]

I think I may have found a minor issue.
After upgrading to 3.6.0-beta.2 from beta.1, my extruder temperature is very inconsistent. Temps while the machine is just sitting idle will jump around several full degrees and when running a print will jump around about ten full degrees.

I tried turning on heater feedforward to see if it would help but M309 P0 S0.01 had zero effect on the results.

To help troubleshoot I downgraded just the 1LC back to beta.1 and the temp readings went back to being within 1deg. at idle and while up at temp.
Below is a screen shot showing my machine sitting at 180C with beta.1 installed and then uploading beta.2. No other changes made.

My machine is setup as follows.
6HC(SBC)+3HC+1LC+1HCL+1HCL.

@Alex-cr yes there is an issue with temperature readings on some 1LC tool boards in 3.6 beta 2. I have a machine with two tool boards and only one of them is affected. I started investigating it on Friday.

@Alex-cr what is the hardware version of the tool board that has this problem? It should be printed on both side of the board.

@Alex-cr please try the new firmware binary at https://www.dropbox.com/scl/fo/kaxbpbsyq2lxbae4tmzpk/AAPVUAh6CO_FMO-cG9ttX6U?rlkey=f0aesppc8d2p7bzwwi2s1jayo&dl=0.

@dc42 The binary for the 1LC worked to resolve the issue. Thanks for the fast turn around and I will continue beta.2 testing.

By the way it is a V1.1 version tool board.
