Perfect Firing At Last!

[TinMaan]

Learning from interesting workflows by members here and other forums, I decided to power the low-voltage part of the circuit with Battery ( that includes the HDMI monitor ) throughout the Firing Schedule. IT WORKED ! No Errors what-so-ever.
I have run a few Bisque and Glaze Firing with success. Aside from a couple of over-shoots especially during the controlled cooldowns, schedules ran perfectly with no short circuit errors that I can detect.
Perhaps I should open a new thread for this question but I like to know : What will happen to max31855 Fault subroutines without earth-GND connection?

What low voltage part are you referring to? And Batter? We are trying to troubleshoot getting our own set-up. And we get the problem reading temp short circuit error alot. Though oddly enough, separately, our temperature threshold keeps stopping at 1500 exactly and then stops the firing process and says it can't read the temp anymore

Proceed with extreme caution as I am not sure about the consequences of depriving max31855 from earth-GND in the circuit by powering it through a battery. As I mentioned, not getting " short circuit " error does not mean you don't have short circuit.
The low voltage part of circuit in my case are the Raspberry Pi, HDMI monitor ( mini HDMI display ) and the cooling fan(s) for the Pi and SSR. Simply power those components with a Battery system that can run the controller for much longer than an average long firing with many hours spare juice. Double check those components don't find an earth-GND. You may get the same results I get.
Again, be aware not seeing Errors is not the same as not having errors.
