BT and ET negative

[ProseCoffee]

Hello,
I have zero knowledge of computer programming, and while I love artisan when it works, it can be a beast for me to fix when it doesn't. I am currently having an issue where I upgraded to the newest version, and now I can't get the BT and ET to register. Depending on what settings I have, it either registers u.u for BT and ET, or it registers as -0.0 for both. I have checked all of the MODBUS settings that I can find, have updated my serialcomm drivers, and have spent hours scouring the forums for other ideas. I am now a roasting session behind schedule because I spent the last one trying to fix my program.
As a side note, since the most recent update, I am also having the crashing issue but it is intermittent, usually when I turn on and reset. I run a Mac OS 13.4.1. I haven't been able to do a roast since updating because I have had the temp issues, but I'm hoping it doesn't crash during a roast.
I appreciate any help with this!

What are you connecting to via MODBUS? Can you tell us what serialcomm drivers you upgraded?

Upgrading Artisan does not change any settings. If you saved settings to a file before the upgrade we can try restoring them (Help>> Load settings). If not we'll start at the beginning.

Hi Dave,
I went through the San Fran website and downloaded the drivers that were recommended for the sf6 on a Mac. It's listed as Isolated USB To R$485/RS422 Adapter 2.0 FTDI Drivers, they're in beta but I'm pretty sure that it's the same one I used before. I just did a factory reset on artisan to see if that would help, but it it's still doing the same thing.

This warning is on the Artisan-Scope.org site.
Watch out! The FTDI driver is preinstalled on virtually all Linux distributions as well as all OS X versions supported by Artisan. Installing an additional FTDI driver on those operating system might lead to instabilities!

That could be the problem. This article may help if you choose to uninstall the additional driver. I don't use a Mac so my ability to help with the driver is limited.

Before going down that path, have you tried going through the machine setup again? Config>> Machine>> San Franciscan then choose the appropriate controller, either SF(Watlow) or Eurotherm.

I had seen the warning on the artisan-scope website, and tried uninstalling the drivers that I had downloaded, but that didn't work either. It also doesn't make a ton of sense because it worked before with the installed drivers.
I have tried going through the machine setup again, it is still giving me the same connection error.
I appreciate your help, I know nothing about these things!

Does your SF have a Watlow or a Eurotherm controller? Can you confirm you chose the appropriate one in the machine setup? The Watlow is the plain SF setup.

I just tried restoring both of the previous save files that I have and neither of them worked, so from the beginning it is!
