Thanks, I didn't know that, it seems to suggest that for 3.5 the new one was necessary, though I do now see the message at the bottom of the page.

Ok I figured out what was wrong. I am an idiot that's what. I inadvertently set the hot end PID parameters as the Bed Parameters in the config.g file.

So, although with a multimeter all tower switch connectors were testing closed at the board end once plugged in they were signalling open. I cut them off and crimped fresh ones and it is working now. Thanks

Thanks for your help. Just wanted to say I got this working by uploading the web control files for 2.05.1 to the SD card then I upgraded using the web interface from 2.05.1 to 3 then 3.3 then 3.4.6 as suggested.

I still have a few issues to work through as though I found an old config.json to use as a basis for the new config, my bed thermistor is reading in negative numbers and my nozzle heater PT100 is not recognised so something wrong in the config.g. I will post another thread in the appropriate section about that if I cannot figure it out.

@jay_s_uk Great, thanks
