Thanks. I had missed sometime to work on this for a few weeks but was able to start to dive into it this week. my goal is to have a working 1 probe 1 heat element working by sunday evening. The hardest part will be mapping the probes to each heat element as they report in with serial numbers that arent really human readable or friendly.
Also I read up a lot on what Aste88 was referring to and really like where their head was at. I will be going with solid state relays, and seeing about a timer based logic to prevent heat elements exceeding a threshold. but that will take time testing and practice. Maybe other ideas to get done what he was talking about.
I will say as I am going through the process, the engineering behind it is a challenge for sure. Trying to make something that gives me all the features, safety logic, and control I want is not easy. But If it was easy it would be already done and a product or everyone would be doing it.
I also plan on sharing my work with everyone once everything is completed as well, so others can do similar if they wish.
