I'm getting a solid 3.3V. I'll send it back to the vendor. Thanks so much for your help!

The z-probe was working fine until this evening. When I ran G32 S2 I got this error "Z probe already triggered at start of probing move" Now the z-probe values bounce around between 1000 and 0 and random values in between and the green probe light is constantly blinking. I disconnected the 6 pin power connector to the Smart effector and removed the fans but this behavior still persists. I checked the wiring and crimps and those look fine. I tried changing the sensitivity but that had no effect. I also tried taking off the heatsink and hotend and that also had no effect on the random values from the z-probe. I'm not sure what else to try. Any help is much appreciated. Thanks.

Hi David,

I tried updating using VIN power but I get the same comm write error. I tried updating through a web browser a few times
and also via USB a few times.

I'll contact Filastruder for a replacement and forward your request about the board.

Thanks.

I just received a new DuetWiFi board and set up the wifi and updated the firmware to 1.17c through a browser. That went smoothly.
I then tried to update the WiFi server to 1.03 and I can't get it to install. I tried many times using different browsers and it gets to the point where the board
disconnects and when it tries to reconnect there is an error that says Invalid Password. I have tried many times using Repetier Host by sending M997 S1 and getting the
same results:

There is a sticker on the Atmel chip that says it's 436/500, maybe that info will help somehow.
Any help with this is greatly appreciated.
Thanks,
Allan
