Can you be more specific...I'm not seeing where I can change this max for after the drop

I dont know what would give you a approx 63degF offset at FC (usually around 370F for Ethiopia on my Hottop). If it's the wrong thermocouple type setting, the graph would look a bit skewed too.

If that's not it, and if you think the scaling on the Y axis looks ok, that the temp error is just an offset, I wonder if Artisan would let you program a pre-defined offset just so the graph gets shifted up correctly.
You sir may be the bomb.com...It was set to J type...Roasting now to see if the problem is resolved. I have a lot of hope now!!!!!!

ETA: PROBLEM SOLVED!!! Thanks so much!!!

J-type is more sensitive than K, i.e., it generates more millivolts per degree. So if your meter is set for J, and you feed it K, the meter will significantly underestimate the actual temperatures.

Use the menu in artisan - see image 1. Then select Config / Axes, and you can change the Min / Max values.

Thank you all!!

Also, that's the settings that I was using...Just making sure that I wasn't missing something with the axes settings....I'm so happy that I didn't tear my machine down
