Ah thank you David! That resolved it!

Good Morning Everyone,
I'm having a weird problem for the past week in that I keep getting an error:

M32 Fan base(0).gcode
Error: M32: GCode file "Fan base.gcode" not found

I tried putting it in the root directory and in a subdirectory, however I keep getting the same error.
I also tried updating to the latest stable firmware:

Firmware Name: RepRapFirmware for Duet WiFi
Firmware Electronics: Duet WiFi 1.0
Firmware Version: 1.20 (2017-12-23)
WiFi Server Version: 1.20b10
Web Interface Version: 1.20

Any and all help is greatly appreciated and thank you in advance

Hi guys, I'm having the same problem..Im trying to tell it to print something but it keeps giving me AJAX errors..ctrl+r a few times, i get in at some point. The print then keeps messing up and having me to reset it, not sure why

I posted the issue on the ultibot forum and someone stated that upgrading to 1.19.2 fixed this problem. I'll try it later tonight and post my results back here

Hello David,
On the Ultibot forums they cautioned users not to upgrade the firmware, probably for their own testing purposes..I will try it later today and get back to you on it

Oh I also reset the cache on both my mac and windows to confirm it wasn't that and tried safari/chrome.

Good Morning Everyone,
I would like to take a moment to thank you for taking the time to look at this thread.
So I finally assembled UltiBots D300VS a couple days ago and every thing seems to be working fine until yesterday when I kept getting kicked out of the web interface due to "AJAX" errors. I ignored it thinking it was the wifi just acting up but this morning I have been trying to connect into the web interface with no avail. Ultibots has not updated their firmware to 1.19 yet so I am stuck on 1.18.1.

1. I power cycled the D300VS, thinking it may help
2. Didn't work so I connected to prointerface to M552 S0 then M552 S1 to restart the server
3. After doing this a few times I noticed it was emitting DuetWifi again, so I reconfigured it to my wifi
4. Didn't work but I saw a post where someone just configured their wifi signal channel from auto to a single channel, so I tried that (Tried M552 S0 and S1 again )
5. Tried updating the router, even though the rest of the devices are good (Tried M552 S0 and S1 again )
6. Then I reinstalled the firmware via the SD card option and then SAM-BA
7. Then I came across a few threads to update the wifi firmware via M997 S1 (Wifi) and M997 S2 (Webinterface)

Alas I came here to post something as I could not find another post (well I did find another post but David mentioned updating to a beta 1.19).

This is the error message:

The "reset reason: Exception" part appears every time I try connecting to it via the ip address (I tried via the host name but that didn't work on my mac or windows)

If anyone wants it this is M122 the diagnostics
