I‘t works fine, thanks for your helps!

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

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

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

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:

@dc42 I don't know, but i solved the problem.

@droftarts I changed the value. I have the problem, the z is 5mm to high during the printing.
I changed the homed heigh from 430 to 435mm but i have g0/g1 error, target position not reachable from current position.
What is the problem?

thanks for your help.

@droftarts It's nema 17 motors, you can using 1.68A on this motor, no problem

@droftarts I changed all the sequences and it works. thank you.

Hello

I have installed the duet board on a Delta Wasp 2040.
Endstop works, but at the end of the Endstop it is not X0 Y0 and Z430.

What is the problem?
