M111. debugging is disabled.

Usb communication works and I can send commands and printer answers as expected. Nothing gets outputed to usb when i start print. The printer crashes every time when it tries to extrude. It does heating and homing just fine but extrusion causes reboot. I tried with another stepper and both have the same issue. I also tried extruding without printing file and it works just fine. Extrudermotor rotates and plastic gets extruded. If it might have had something to do with bad acceleration settings, i tried to tweak those too and it actually was the reason.

I had
M566 X800 Y800 Z30 E0 ; Set maximum instantaneous speed changes (mm/min)
M203 X15000 Y15000 Z1200 E3000 ; Set maximum speeds (mm/min)
M201 X1000 Y1000 Z1000 E3000 ; Set accelerations (mm/s^2)

And for some reason this caused firmware to reset. Maybe the accidental 0 in instantaneous speed changes or something? I changed that to 10 and max acceleration to E500 and seems to work now. Still i have occasional Ajax errors but at least now i can print (at least for a while, havent still tested full print)

Not sure if this is from last crash (as it was in the morning and I dont remember if I did something after that) but here it goes:

I'll post new reason when I get another reboot.

EDIT: Ok, I get crashes constantly when trying to print something. This is from latest crash:

Had the same opcode error problem. Solved with fallback method #3. I flashed firmware with bossa and it helped.

Hi,

I updated firmware 1.9 yesterday. Now I'm having constant Communication errors: dwc.js:1 GET http://192.168.1.100/rr_status?type=1 net::ERR_CONNECTION_RESET

I tried to increase maximum number of AJAX retries to 10. It helped a lot, but I still get errors some times. Also increased Status Update interval from 250ms to 500ms. Also the printer booted (?) itself while printing. It happened 2 times, I'll try to reproduce it so I can debug why it's rebooting mid-print. Printed worked fine before update.

UPDATE: When the connection error happens and I try to press connect: XHR failed loading: GET "http://192.168.1.100/rr_connect?password=reprap&time=2017-8-17T15%3A21%3A8". For some reason dwc tries to use default password "reprap" to reconnect. I have changed the password. I cant reconnect to printer without refreshing the page and manually entering password again. Also seems that printer just rebooted midprint again at the same time this connection error happened…

I also installed one new stepper motor at the same time as I updated to 1.19. I'll try to reconnect the old one and "cold print" to test if this still happens with old stepper motor.

Ok, actually just figured why it wont connect Always happens just after you ask something. Asus VPN assigns ip from pool 192.168.10.xxx and other network is in 192.168.1.xxx, so I suppose duet is stricter than other servers in my network..

Hi,

I'm having problems connecting Duet Wifi gui trough VPN. I can connect just fine when I'm directly connected to my home network, but when I try to connect from outside my network via VPN, duet gui wont load. I'm using VPN in my Asus RT-N12D1 (just normal PPTP VPN). I can connect every other server in my home network just fine through VPN but duet interface has some problems with it. Any idea what can cause this? I don't want to forward any port so I haven't even tried that.
