Delta with New Duet 2 WiFi Only homing on y tower

[KeithW]

I have installed a new Duet 2 Wifi and currently have firmware 2.05.1 installed. I have used the RepRap config tool to replicate the old settings from when I was using the Duet 0.8.5 as best as I could but when trying to home it only moves the Y tower. My config.g looks like this:

I just don't even know where to begin but I will say that I can use the dashboard to move the print head up and down with the Z+ and Z- buttons and all towers move fine and apparently evenly.

[Veti]

can you post the output of m119?

[KeithW]

M119
Endstops - X: at max stop, Y: not stopped, Z: at max stop, Z probe: not stopped

[jay_s_uk]

@KeithW And when that was taken, were X and Z towers at their maximum?
If not, then you have issues with your wiring

[KeithW]

No they weren't, I will check the wiring and let you know.

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
