Hello All,
I have a previous thread with help on my TC probe here:
https://tvwbb.com/showthread.php?74951-Thermocouple-Works-on-RD3-but-not-on-main-board&p=823281
It seems to have resurfaced as I was seasoning a new UDS I built. After a couple of hours running HM and microdamper the TC went all over the place jumping between the actual pit temp and anything up to 700 degrees. I tried a different TC probe with the same problem. When the HM is cool the TC seems to work fine.
So I brought unit in to capture some data. I ran the hm-noise firmware. I have uploaded pictures of the setup as well as the csv of the problem, also the temp of the Pi at the time. Also it should be noted that even when the TC was grounded with jumper it still kicked out a very wrong temp.
It has been some time since I did the clean up of the board as noted in the previous thread.
Other things I have tried include testing the extension cord used. Changing from a wall wart to a battery backup pack. Tried two different TC probes. Nothing seems to work. I have tried with the AC filter on and off.
As to the seasoning when I disabled the pit probe and ran off probe 1 the HM ran fine for nearly 24 before my charcoal road bit the dust so otherwise HM is running great with WiFi and fans and dampers all working as expected.
I even updated to the latest snapshot build in the middle of my "cook" yesterday and no changes.
You all have been such a great community thanks in advance!
Here is link to Dropbox with screenshots and pictures of HM and a csv running the hm-noise firmware.
