Currently i have two issues that are probably related.
The first one is related to the IR sample. After the printer was set up and adjusted, I installed the fan for the components.
Since my IR Probe still works conditionally. I must switch on the fan first after switching on the printer, only then the IR probe flashes and is activated. If I do not do that, the Hotend goes to bed because the IR does not respond. When restarting the same.
The second problem is Auto Mesh Bed Compensation, where at the end no graphic but an error message is displayed.

Hello everyone, after I was able to bring my board back to life with Bossa and the latest FW 3.4 update is now running, I wanted to update the Paneldue V3 5" last but not least.
Unfortunately I get the message: M997: Aux Port 0 is not enable or not in Paneldue mode.
What do I have to do to be able to install the latest update?

The board is up and running again...thanks to Bossa.
Thanks for your help

@droftarts Sorry, but i can't find any www folder on the Duet2and3Firmware-3.0.zip
I have had the config file converted by the RepRap tool. Unfortunately, still without success. The terminal programme searches for a different FW version: Error: In-application programming binary "Duet2CombinedIAP.bin" not found<LF>ok<LF>

I am currently trying to do the following: Rename the iap4.bin file to Duet2CombinedIAP.bin. Then start the update in the terminal programme with M997 S0 and the display says Firmware Download......and nothing happens.

Hello everyone, my existing problem with the update: Previous version: 2.05, wanted to update directly to 3.4....unfortunately this was probably wrong. Now I have updated the main firmware (Duet2CombinedFirmware.bin) and DuetWiFiServer.bin to 3.0 via console using M997 So and M997 S1, which also worked without errors. The terminal programme displays the following with the command M115: FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.0 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2020-01-03b3<LF>ok<LF>. However, I still cannot access the printer via the Duet Web Control. The browser only shows Connecting and Incompatible Firmware Version. I have read that the Config.g file also needs to be adjusted Need urgent help on this....Help....Help
And if all this works again at some point...should I take the step to version 3.4.0?

Hello,
problem found, cable from the limit switch is broken, therefore wrong switching states to the controller.

After felt 10 rolls of filament my printer starts to do strange things.
After the temperatures are reached, homing begins. The Y-axis moves normally to the limit switch and the X-axis literally creeps there (very slowly). Then the print head moves in the middle and Z-homing starts. Now the pressure starts in the middle and sometimes by a few centimeters next to it.
The printof the part is absolutely normal. The X. axis also moves at normal speed.
At the end of the print, however, the bed moves to the print head and crushes the finished print part.
Can someone help me?

@dc42 said in IR Probe and the Fan !?!:

May I mark this as solved then?

Yes gladly

@dc42
Yes, with Windows PC and my Iphone it works well. Mesh Bed works well

Found a mistake. This only occurs with my ubuntu 16.10 notebook.
With the phone and windows pc crashes and can show everything.
The wiring and solder joints are great.
