Hi, yes I read that but that can't be legal, can it? I can't find any reference to a 6-month warranty for online selling rules. Given the price of the board, you'd expect it to last at least a year or two given the light use it has had. Hopefully, I'll hear from the duet team when they are back at work.

@bearer It could have been a bit longer but I tested for continuity between each leg and the pads on the front and back the best I could. I'm going to try and hunt down a spare wifi module just in case

Thanks! hopefully, it will keep going now. I examined it close up and couldn't see a bad solder joint so I'm guessing it was bad solder somewhere in the module.

I managed to fix for now I masked around the wifi module with Kapton tape and gave it a blast with a heat gun for 2 seconds. I've handled it and restarted it a few times and it seems reliable again now.

Hi, David, the board is not dead just the wifi module has stopped working. The wifi just reports as starting all the time although it did work for an hour or so last night. I've read all the forum posts I could find on the issue. I'm in the UK.

The wifi on my Duet 2 WiFi was intermittent but is now dead I purchased the board directly on 15/11/2018. this is still under warranty, isn't it?

To be fair the bed is pretty shabby It was an Anet A8 and came bent from new. The bed, 1x end stop and the motors are all that's left now. I have a feeling its too out of true even for mesh compensation but I can see that working watching the z screws constantly moving.

I use a Prusa spring steel sheet with PEI on it, all held in place with magnets and bulldog clips.

I've got a new bed on its way in the post next week but I know how to set the probe up now thanks to yourselves. I think I'll look at different probes and try and get it as close to the nozzle as I can.

Thanks for all your help
All the best Andy

Yes, I was 0.2mm too close to the bed so used the baby stepping to raise the nozzle.

@phaedrux said in Z probe offset always prints in the air.:

add an X Y move to position the probe where you want the bed probed before you call G30

Thanks for your help I've got a lot further and am actually printing on the bed now I don't understand how to do the X Y move to position the probe where you want the bed probed. If use the baby stepping and added 0.2mm do I need to add or subtract that from the hight I set in the config.g?

I've got soo much to learn about RepRap.

Thanks Andy

I've got this in my home files now.
