Reply to Blackfinger about handle extension ports. Yes it is possible, but you have to do it yourself and bear all negative consequences that could be happened. I can give you just an idea. You can follow afedorov advice and separate one extra pole for MCLR reset or go direct trough power cycle using the same switch. Bear in mind, that if you want fast response from the handles, you have to preheat them to 180 C using some current limiter.
Thank you sparkybg for the awesome project. I also met calibration problem and replacing the two resistors R57 and R59 in my case with bigger value 1.8k solve the problem by increasing the temperature by 25 C, by the way , I needed only 5 to 10 C. Answering to the ccb about OLED board connection, I attach a pic of my Uni Solder, not finally finished, but fully functional, I am waiting 1.3 inch OLED to arrive and I am using JBC T245A. I really can claim that Uni Solder is my favorite solder station.
