After Firmware update on Duet 2 Ethernet from 2.04 to 3 Error

Hello
After update on Duet2 Ethernet i have a Problem when i heating the Bed.
It show me an error: Heating fault on heater 0 temperature rising more slowly than the expected 0.8°C/sec.

here my config:

Have you re PID tuned it?

M303 H0 S70

for example

goodchrhere

No, i will do it now. Thanks, i will reply after

@jay_s_uk Thanks, it works. i'm stupid xD

No you're not, it's something I overlooked. In RRF2 the bed heater used to default to bang-bang and a different heater model from the extruder. But RRF3 doesn't know how you will use a heater when you create it, so the default heater parameters are OK for some extruders but don't suit most beds. This means you might get away with not tuning the bed heater in RRF2, but you probably won't with RRF3.

okay i understand, it work by the 3d printer in the company. At home i have the same problem. I tuned the bed, and it will be heat up. but when i set 50° for bed, it will heat. After to reach 50° the voltage from 12V goes down to 9.5V. I have a 12V bed with a ssr.
The heatbed https://www.3dware.ch/MK3-Alu-Heizbett-400mm-x-300mm-De.htm
The ssr: https://www.aliexpress.com/item/32756137315.html?spm=a2g0s.9042311.0.0.27424c4dRuqXvc

In rrf2 it works fine and in rrf3 it give an error.

goodchrhere

Has my bed malfunction, or my ssr?
Or have i a false phrase in rrf3?

This indicates an underlying hardware problem. It may not have been as obvious in RRF2, but it was there.
