what can "cause: reset button or watchdog"

Potti5

I have bigbox printer with idex gonfiguration. I dont had any problem before this.

Everything started yesterday. I had printing on going and suddenly u-axis titan extruder start skipping steps and i have to stop printing.

Extruder bearing was jammed and i change it to new one. It work again.. i think.

Today i start to print same print again. everything goes well until i noticed u-axis was skipped steps and print was fail.

I start to printing again and after first layer Duet board reseting itself and print stopped. I try again and this time reseting happened on layer 6. Now i put voltage meter to measuring if power is going down and i start print again. Power is ok voltage is steady 24.25V but still duet reseting. It happend every print between 1 and 6 layers. I also try to print with X-axis and same thing happen. Any good idea what causing this?

Please upgrade to firmware 1.21.
Please check that the edge of the Duet is not pressing against a back panel or anything else that could be activating the Reset button.
If you are using a USB connection to the Duet, see https://duet3d.dozuki.com/Wiki/USB_ground_loops.

No usb. Only wifi.

Result

Duet reseting print on layer 2 and also wifi going down. Now i cant connect it anymore with wifi.

M122 i get it with usb

taking power off get wifi up again

Potti5

Is a possible that u-axis stepper motor can couse this? I take that plug off and now print is going on layer 10.

It skipping steps when this started and it never skip before. I drive it manually yesterday and it work well. Intresting....

dc42

If disconnecting the U axis motor solved it, here are some possibilities:

Insufficient power to drive all the motors
Bad U axis driver - is it getting hot?
Short in U axis motor wiring

Potti5

It look like it would work now.

I have had this idex setup about 6month now and i am printed quite lot whitout problem. This print is printed only one material so only one (u or x) motor is used. Both axis have same kind and tall wiring. I check board with thermocraphy cameras after this print so we see how much those driver warm up.

Maybe i could also try to place u-axis motor to another driver before i start to change that motor.
