Thanks for the replies guys but rather embarassingly it is now working ok. I feel such an idiot. I don't know why all of sudden it works fine. The only difference is that I didn't have the usb cable connected to machine or YAT terminal open.
Would that prevent the DWC from opening?
Anyway at the moment I am back printing.
Thanks again for your replies. Always nice too know there is someone there to help.
Cheers

Hi.
I have not used my printers for a while but went touse them last night and I cannot get the DWC to load. The only change since I used the printers last time is I have a new router and provider but the network I use in my garage is still the same and works fine. The printers connect to the network but I cant get the DWC to load. I connected YAT to check the details andd I got the following.
M552 S1
<LF>WiFi module is connected to access point Wireless-N, IP address 192.168.0.24
If I ran M587 I got a the same remenbered network but different IP address of 192.168.0.14.
I thought it best to get rid of the remembered network so ran M588 S"*" and got rid of all networks. Ran 587 S"SSID" P"password".
M552 S1 and I am connected to Wireless-N IP192.168.0.24 etc.
So this is where I am getting stuck. Printer is connected to network.
I type the IP address 192.168.0.24 and I get "Your Duet rejected the HTTP request: page not found
Check that the SD card is mounted and has the correct files in its /www folder"
I dont know where to go from here. Nothing else has changed.
Any help please?
Best regards
Paul

OK. Update.
Printing the benchy after modifying the outlets made it worse.
Reverted back and this time I started the fan at layer 3. Fan at 75% and temp at 220 degrees. This time a marked improvement. The first 9mm (or 180 layers are ok.•No lumps and bumps) From then on it is perfect. I have to eat humble pie and say I do need cooling but I think my cooling duct needs refining as maybe its not quite hitting the right spot.
I altered the config as per values posted by Phaedrux but it made no difference to the temp. After taking readings with a thermometer the hot end is still at the indicated temp both before and after the changes.
Thanks to all for the advice. I certainly learnt something.

This is my config file

Its from TCMUK-3d. NTC Thermistor Brass Cartridge 100Kohm

This is config entry for thermistor.

I've just altered the cooling outlets to point more down so as not to blow across where the filament is laid down. Got a feeling they may have been cooling the filament as it was going down so maybe cooling to quickly.
Just printing a benchy now.

Thermistor values I think are correct. I did a PID tune and set the values. The temp is rock steady as is the bed which is mains powered heated mat.
The cat was printed with the same setup.
Not using pressure advance. 2mm retraction set up at moment.
Printer is set at 2400mm/min.
I print first layer at 40% speed as I find this gets a good first layer. The outline is set to 40% as well.
So first layer prints at 16mm/s with the outline at 6.5mm/s
Thereafter everylayer prints at 40mm/s with the outline at 16mm/s.
I chose the fan to come on after 10 layers as this seemed a good point to start.

Ok. Update.
Tried printing a benchy at 215 degrees and 100% fan. Set fan to come on at Layer 10 (2mm). That was the end of that . No layer stuck after that and no, my cooling outlet is not blowing at the nozzle but at the print.
I printed an overhang test piece firstly with no cooling and 195 degrees. Printed ok until about 50 degrees overhang when it got a bit messy. Then I printed it at 215 degrees and 50% fan. About the same quality but had no strength. Could pull it apart easily. I'm using Sakata 3d filament. Now going to try Rigid Ink filament.
The daft thing is that when this was a standard printer I could print a benchy no problem. Since upgrading to a genuine E3D and a Direct drive extruder I have had all these problems. I guess that is the answer. Revert to original.
As an aside my delta with a duet board and a E3D and Flexidrive extruder also prints a benchy no problem with no cooling.
It makes me think that 3D printing is not an exact science as some make it out to be.

But does not the cat I printed have overhangs?
