Status "Off" means that the VIN monitor thinks the input voltage is below 9.5V. Normally the printer wouldn't be able to run at this voltage, but of course you are using all external drivers and no heaters. Were you powering the Duet from USB or other external 5V power only?

@kulitorum I also noticed that you are still running a release candidate (RC3) of 2.02. I think you should update to final 2.02 as this might already fix the issue.

Kulitorum

@dc42 But as you can see, the input voltage is 27.9v.... Maybe I just burned the input regulator-thingy?

dc42

No, the voltage sensing used to set the state is the same voltage sensing used to display the max/min input voltage.

Which firmware version are you using? You said 2.02 earlier, but your M122 report shows 2.02RC3.

Kulitorum

So.....I guess my Vin could have passed 30v for a while, and burned the input voltage measurement circuit, making the duet think that its underpowered and causing the board?

Than again, the M211 command reports : Supply voltage: min 27.8, current 27.9, max 27.9, under voltage events: 0, over voltage events:

So....?

And its still "OFF"

dc42

M122 only shows you the min/max voltage since you last ran M122, or since power up if you haven't run it yet.

I suspect that the voltage reached 29V, which caused the firmware to switch the drivers off to help protect them. They won't be switched on again until the voltage drops to below 27.5V. Since your minimum is 27.8V, that won't happen, so the printer remains in the Off state..

You were right. Taking the voltage down to 26v fixed the problem. thanks.

Kulitorum

Maybe add a warning message to the "!" in the top left corner?
