@dc42 Thank you.
If I understand you correctly, the actual stepper motor wire colors should then match the connector color codes on the Duet WIFI wiring diagram?

The connections would then look like this:

Stepper Motor / Duet WIFI:

B+ (red) / 2B (red)
B- (blue) / 2A (blue)
A- (green) / 1A (green)
A+ (black) / 1B (black)

@Phaedrux
It's a 220V silicone heater,
similar to this one:

@dc42 here is my config files.
I have added the command "M570 H0 P10 T5 S300" suggested by @deckingman and this seems to have helped.

config-override.g
config.g

@deckingman
Thank you, I will try this.

@matt3o

M303 H0 S70
M307 H0 R0.363 C315.930:315.930 D5.30 S1.00 V24.4 B0

If only it was this easy.
I am already doing this every time.

My printer is practically unusable at this point, since the bed heater algorithm faults it almost every time i turn on the printer.
Is it possible to change the check, so I don't need to perform a M303+M307 every single time I need to use the printer?

Always the same error:
Error: Heater 0 fault: temperature rising much more slowly than the expected 0.2°C/sec

Colormatching worked.
Thank you very much.

Now I have to figure out why my Y axis is reversed, but that's a different challenge.

I am building a Hypercube Evolution, and configuring it as CoreXY using the RepRapFirmware Configuration Tool.

The board is a Duet WIFI Rev. 1.04
Firmware version 2.0 (RTOS) (2018-06-05b3)
WiFi Server Version: 1.21
Web Interface Version: 1.21.1

I am using five of these Nema 17 stepper motors: https://www.omc-stepperonline.com/nema-17-bipolar-45ncm-64ozin-2a-42x40mm-4wires-w-1m-cable-and-connector-17hs16-2004s1.html

These are wired to the E0, X, Y and finally ZA and ZB in series. (Dual Z axis version)

The wiring is done like this: (Wire colors are from the stepper motors)

But I am having trouble getting the system to run.

Every Z, X, and Y test seems to trigger Z movement.
And the two Z stepper motors seems to turn the opposite direction of each other. One clockwise, and the other one anti clockwise.

I have checked the wiring multiple times, and they are all connected the same way.

Am I missing something important?
