Ok I figured out what was wrong. I am an idiot that's what. I inadvertently set the hot end PID parameters as the Bed Parameters in the config.g file.

RE: Delta with New Duet 2 WiFi Only homing on y tower
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

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

Delta with New Duet 2 WiFi Only homing on y tower
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:

and my homedelta.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.

Duet 2 Wifi with generic Max31865
Hi All,
I just want to confirm what I am doing is ok and correct and to get some help with some configuration.
I have upgraded my Duet 0.8.5 with a Duet 2 Wifi running Firmware 3.11. I already had a generic Max31865 for my PT100 sensor and want to continue using this with the Duet 2 as it works OK.
Previously I have it connected to the 50 pin connector as shown here. Now on the Duet 2 WiFi I have it connected as follows.
Is this correct and how do I go about telling the Duet which channel to use? Would is be as simple as adding this
M308 S1 P"spi.cs0" Y"rtd-max31865"
to the config.g and what M950 command would assign it to the hot end?
Thanks

RE: Error: Heating fault on heater 0
OK so with my bed removed and carefully placed on the side but still fully connected I can see that the light on the duet comes on and the light on the SSR comes on for a short time then the error occurs and they both go out so I think this is either a fault with the Duet or with the configuration maybe but as nothing has changed in the configuration I am unsure why it should suddenly start behaving this way. I have checked all the connections are still good and tight . I am unsure how it determines that the temperature should rise at 1.7°C/sec.

Error: Heating fault on heater 0
Error: Heating fault on heater 0, temperature rising much more slowly than the expected 1.7°C/sec
So a few days ago I posted that I was seeing hot end temperatures about 25°C high at idle and that after taking some bits apart and putting it back together that it seemed to be working. Shortly after I started to get the above error when the bed has reached about 30°C.
I checked the silicone heater and it seemed to only be getting warm in one spot so I assumed that it was faulty and I have procured a replacement but now that the replacement in in place the error persists.
My configuration for the Bed is
M305 P0 T100000 B3950 R4700 H-20 L0
but this has not changed since I started using it.
My Printer uses a mains voltage heater through an SSR. I do not really know how to troubleshoot whether it is the duet, SSR or Power Supply that is at fault but I am assuming the PS is ok. I am open to suggested troubleshooting methods.

RE: PT100 reading too high
And now that I put it all back together its reading 30°C which is only about 3°C high compared to the bed temperature. Maybe a bit or tarnish on the connector or something, I will keep an eye on it.
