I tried to use the example from https://github.com/frank26080115/HephaestusConfig/blob/master/other/esp32cam_sketchbook.zip but when I compile I get an error. Has someone the same problem?

Yes, I am Running now 2.05.1.

But now i have a new stupid question. I can maximum choose 235 even though in the config 280 is set as maximum

I think its working now, i was too stupid to activate the heater 1 in the DWC

Heater is e3dv6 and connected to E0 Heater on the board and the thermistor is an genuine atc semitec 104gt connected to E0 thermistor.

M98 PCONFIG.G shows the following:

HTTP is enabled on port 80
FTP is disabled
TELNET is disabled

Many thanks for the feedback. I think the update to version 2.0 worked. DWC shows now the hotend temperature.

But now i have a new problem, the heater is off and will not heat.

I am really sure that i have done the wiring correct.

I will try it. Just to be sure, i have only to download 2.05.1 Duet2CombinedFirmware.bin with 402KB and Upload via DWC?

I use Firmware version 1.21 and DWC 1.22.6.

I use an e3d v6 with an atc semitec 104gt.

Hi everybody, I bought an already used Duet Wifi and everything works fine except the thermistor of my hotend heater. The thermistor is only working if I upload the config.g file new. If I open the DWC after that again thermistor is showing n/a and I have to upload the config.g file again.

Does anyone already knew this issue? Many thanks in advance for feedback.
