Ye should for sure tidy it up. Thanks

Its a 24v 220w creality bed.

Yes tested and voltage present. I cant see any damage other than the smell of something popped.
New board it is. Luckily i have a duet 3 to hand.

How do you think the mosfet failed ? Everything is crimped with a good few years of experience behind it and some pretty bouji crimpers. The board is only a year old . Its pretty suss with no route to a warrantied repair service

Hey @phaedrux

Yes it does unfortunately

I have a cartesian machine running off a duet 2. No issue to date. I was printing some tpu with the bed at 55 degrees and the printer stopped printing a couple of minutes into the print .

Now each time i switch the printer back on the temperature climbs even if the bed temp is set to 0 degree.
Ive checked the wiring all seems ok and had not been touched or amended but i do smell some of that classic POP smell.

The 15amp blade seems all good.

What do you thing is going on ?

Thank you kindly. Works a treat on the X axis. Will give the adjustments positions a go also.

Ive added a G29 into the bed file after the probing as if it were a macro when I G32, Is this ok ? Prints are coming off nicely and bed seems very level after adjust from the mesh.
I only ask as I’ve never seen a Z adjust notification in commands.

Hello,

I have a cartesian bed slinger with a 310x320 bed. The z motors are independent and I’ve been wanting to implement G32 before i G29 so that the gantry is level before mesh bed levelling .

Ive whacked the leadscrew positions in (m671) and set the probing points in the bed file with g30 commands.

I was wondering where is best for me to probe. At the middle of the bed each side of the x gantry or probe at the adjustment screws in each corner

If the latter is the case, the probe cant reach the left side screws. What should i do in this instance

Regards

Iwan

Oh no bobbins.

Ill retrace my steps. I wouldn't say im 100% pcb literate but enough to say its likely goosed.
The printer still homes and is responsive via DWC. I’ll run a dry gcode and see its behaviour, report back

Would Duet recycle the board if i sent it back ?

@t3p3tony

Compared with another duet 2 wifi I have, L6 and L5 are blacked out and it expelled a waft of “component pop” in the air when switched on.
The Bl touch no longer lights up and is unresponsive, previously the Bltouch would probe test on start up.
Multi meter has confirmed that these have blown. Currently looking at schem to see what else has been affected.
I think its a goner.

No amendments have been made to the wiring over the past 24hrs. Sheathed the bltouch cable with some paracord and recrimped is all. Red to 5v, yellow heater 3, black / brown to ground, white in. The bltouch is a 3.0 and my understanding is that the duet 2 is 5v tolerant.
This is my 3rd duet on one of my printers and I know the pin out pretty well… I’d be surprised if I had “F upped”

Ive never had an issue with a film resistor blowing like this out of the blue but im absolutely bemused to how this has happened and the gradual degradation ive seen over the past few days

Is it worth sending it over for inspection?

@siopshop @T3P3Tony
Apologise foir the heic

@t3p3tony
Unfortunatley it became unresponsive shortly after. Ive attached a pic of the board below and it looks like L5&L6 has burnt out. Could you confirm ?
