Thanks David, All sorted now. I think I may have used the 2.05 combined file and also the backup config file I used had an old router address on. Anyway back up and running again.

@dc42 It was in the 2.05 bin, but I thought I used the combined file. Will use the 1.26.1 one and let you know what happens.

I'm not sure if my duet is fried, but I had to erase and reset my duet 0.8.5 and I have tried installing 2.05 but at the moment it won't do anything, no ethernet connection and no movement even using the display. I cant remember what the latest software I can install is. I think I had Duet2Firmware-2.05.1 installed (and 1.15 on the paneldue display). Is this correct and can I just install this or do I have to install Duet firmware 1.26.1 first? I will try again later today using Fallback procedure #3 (https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware_(Legacy)).

Thanks.

Having just rebuilt and recalibrated my printer I was having a lot of problems with first layer adhesion.
I used the Duet setting up guide, but the nozzle always seemed to be to far from the build plate to adhere properly.
I have adjusted this within simplify3d by adding a -0.15 offset. Problem is old Gcode files are now unusable.
Is there a better way within duet, such as adjusting the sensor trigger height or some other way.

I bought it through amazon, and I have just heard back from the supplier who suggests taking the covers off and looking inside. Not sure if I want to do that as it may cause warranty problems. Also I don't think its the fan. sounds like transformer noise to me and its the opposite end of the case to the fan.

The one I have is this one.

The fan is on the end of the case

Thanks Arhi, have contacted seller so see what he says. Have also contacted uk distribituter who thinks it is genuine so not a knock off.

This is the power supply internal fan.
Judging by the screw spacing its a 60mm fan.
Also just listening to it the noise seems to be from the centre of the case so maybe not the fan.

Just got a 600w 24vdc Meanwell power supply and the fan is very noisy. Am I just unlucky or are they quite noisy?

Great that sorted it. Was getting a bit frustrated with it, but hopefully sorted now
