No its not the serial line, it's the reset line in the serial cable.

No worries. I haven't tested with printers, SD2IEC or ulitmate II. I also presume they will be ok since the will be held in reset after the pulsetrian of serial...

How is it going with the project. I'm about to build this myself. No expereince, though did you measure using teh four wire technique? (Two wires Pass a constant current,...

I don't see any replies from the maintainer here. Maybe I can have a look at the code this weekend.

I'm experiencing overcurrent. I'm feeding in 12V from my lab power supply set to limit current at 5A. It doesn't take long for the regulator to go beyond that limit....

My video on this board. https://youtu.be/bX83ZVMr6Pg Findings. Resistance is too low to produce heat up quick enough at sensible current levels (5A). This cannot be fixed without reducing the trace...

At mouser, the ATMEGA4809-AU is in stock, but the AFR version (125C version) is on order with long lead time. Not sure how hot the microcontroller will get.

Hehe. Be quick 😅. I have ordered pcbs of heatplate 1.1. I was thinking of swapping out micro in the design first, but then there is the software as well.

I'm finally building the hotplate 1.1 after a long pause. I'll give some feedback If I find anything worth mentioning. Ps I'm planning to do a youtube video as well.
