Dear Paul. I made my version of the PCB and it works... Here is how it looks: https://i.postimg.cc/50CvGXLJ/IMG-20190211-133124.jpg I decided to use 200W 19V laptop PSU which is enough for T245, but when I switch to HT420 tweezers the supply turns internal protection and stopped due to the high current consumption. Seems like both heaters inside the irons are getting juice from the supply simultaneous which is not good I think. So can you modify the code so only one heater to be powered at the same time?

I have another strange issue- the OLED display doesn't power on every time. I improved it by adding 10k pull-up resistors. but even that sometimes it doesn't start. I'm not sure if this an issue with the display or the code.

And one last wish for help: I swapped ENC_A and ENC_B pinouts for easy PCB arrangement but even if I change them form: const int ENC_A = 7; const int ENC_B = 6; the encoder reduces the value moving CW not CCW.

Any suggestions?

Best Regards. Niki
