Yes was working in digital mode - I found the problem - a second M558 in config by mistake -thank you for your help

I cut the ends off a shielded USB cable, crimped three of the four cores and connected to the Z Probe socket on Duet Wifi

M558 P1 X0 Y0 Z0 H6 F200 T5000
G31 X0 Y-20 Z0.57 P500

I am fitting a new IRProbe and it always turns on in digital mode (2 flashes) - i've checked all the wiring with continuity tester at both ends of cable but cannot find a problem - any other troubleshooting tips ?

Thanks

You could do everything on one pi - you don't need a separate one for the LED's

In another thread it was discussed to add an exception for trigger 0 so that it was prioritised over running macro events. Purpose being to have the ability to add a physical emergency stop using a micro switch
Is this possible?

Its out in the open at the moment - there is space inside the controller box but I am going to repurpose the LCD for an arduino project so I think I will print a new box for the Duet.
As the PSU fan is now the noisiest part of the printer I think I will switch to a computer PSU with a larger quieter fan in it so will end up with a custom case for that also.

Got the upgrade done ok - very pleased with the Duet - everything is so much quieter

First couple of prints didn't work - I hadn't set the Z steps / mm correctly - but once that was done next couple of prints were great. Very pleased

Next up is to figure out how to mount the IR Probe

I will post the settings I used later

Hi - I'm going to upgrade my Wanhao i3 duplicator to Duet wifi this week. http://wanhaousa.com/products/duplicator-i3-steel-frame
Was wondering if anyone else had done this upgrade or any general gotchas I should watch out for with this type of prusa printer?

It currently has a meizai marlin controller with MK 10 single extruder.

I'm really looking forward to adding the IR probe for levelling - would be grateful for any guidance on best way to mount it. I think there is enough space next to extruder but worried about heat and how to attach it.

Look forward to any advice you can offer - I will take photos and take notes as I go.

Hi - is it possible to order the IR probe seperately ? I can't find it on either site

Thanks
