You bloody star - excellent. That worked.

Thank you.

@jay_s_uk - HI Jay. I tried that but it's not responding at all. Just FYI It was working fine just before the board switch and, TBH there's not much to go wrong from a hardware POV. So it must be something I have in the config.

Hi. I have just changed my Duet board (I had a fault on the heated bed which caused the last one to get very melty) and , while I have most things working now, I cannot get the hot end to work at all. I have check continuity from the board to the heater and that all looks fine but as soon as I try to turn it on I get a "Not heating up fast enough" error. In fact it's not heating up at all and even the E0Heater or E1 Heater LEDs on the board aren't lighting up. This is my first brush against RR3 and I've probably got something wrong in the configuration but I have now run out of knowledge and cannot see the error. What have I got wrong?

TIA.
