Z endstop at high end should set Z position to maximum

M305 P0 X503 R ; Configure PT1000 for heater 0
I think your PT1000 config line is missing some parameters.

Oh, now I see it thanks. I chose the PT1000 because, if I understood right what I read, are supported without adapter and was able to buy some at Conrad on a Saturday. Meanwhile I ordered a thermocouple adapter board, that is, hopefully, on the way today. I have K-types at home. Now I recall that printers usually use 100k NTC for the bed. Is this the NTC the way to go for best serviceability? Precission is not that much an issue on my opinion, because you need to tweak to filament and bed anyway.

NTC and PT1000 are both supported without adapters. Thermocouple and PT100 adapter boards are available. Its mainly a question of accuracy, operating temperature and cost, pick two type of deal.
Oh sorry, I need some practice on reporting here
You'll find most of this applicable to the internet and life in general as well; https://forum.duet3d.com/topic/5909/guide-for-posting-requests-for-help

@thomas_rudloff NTCs are fine for beds. I use 1% Epcos B57861S104F40 epoxy bead thermistors that come with PTFE covered leads. I attach them with JB-Weld.
At typical bed temperatures 1% is only a degree or so so I don't see any point in being more accurate. It would be a good bed that has less temperature difference across its surface.

Thanks to all
Just deleting the R does the trick. I read somewhere that on newer boards the defaults are OK.
