@PeteIHughes said in Duet Wifi Powers Off when turning on Hot End:

Thanks for the Ideas guys.

Checked the resistance at 21.6 ohms, so I am guessing that's close enough.

While checking the PSU, ran into a "small" problem.
How can I test a few amps of load on it?

I thought, simple, just connect the heater cartridge directly across it.
I "probably" should have been testing the 24v side, but no,
somehow I connected it across 115vac.
Turns out the heater cartridge probably worked, as it went from
room temp to white hot in less than a second.
I'll be ordering a new PSU this weekend.

Looking on the bright side, It was probably that anyway

Report back in a few days

I hope it is the PSU and not a MOSFET on the board.
Good luck.

Check the resistance of the cartridge. 30W at 24V should be ~19.2 ohms. If the resistance is a lot lower, you could have a bad cartridge or a short. If the resistance is correct, check the PSU. Put a few amps of load on it and see if it cuts out.

... I've opened a dispute with Aliexpress ...</snip>

Any word on the verdict? Curious as that dispute "system" is a bit hit and miss at best imo.. If you paid with PayPal they have a much better counterfeit item policy, full refund no return - Ali might do the same, if the planets are aligned..

I've heard nothing back from them yet, and I'm not going to hold my breath or expect a satisfactory solution.
I'm expecting to be told that I have to send the board back to them at my own expense, which, although an outrageous suggestion when someone has deliberately set out to deceive you, is the same reply you'd get from PayPal in the same situation.

@theruleslawyer The board does have the disclaimer on the back, but the back of the board was not shown in the advert.
The "PanelDue 7i" that came with the board is also a joke. The top of the buzzer sits about 10mm above the top of the screen, whereas the real one looks flush (which would make sense). No doubt they saved a cent by using the cheapest buzzer they could find. It's a shame they didn't give any thought to mounting the panel in anything.

@dennishall I definitely won't be keeping the clone. I wouldn't trust it to not burn the house down whilst I'm in bed with a print running.

I have nothing against clones, per se, so long as they're advertised as such, and the original hardware is open source, but I do have a lot against someone passing off a clone as an original, which is exactly what happened here. It wasn't an oversight on the seller's side, it was a blatant attempt to rip people off.

I'll post back in a few days when Aliexpress have stepped in and made a decision.

@t3p3tony I did report them to Aliexpress, and they immediately changed the title of the advert to include 'clone'. Unfortunately it was too late for me, and, according to the seller, my only recourse is to send it back at my own expense, but I've opened a dispute with Aliexpress, as I despise underhandedness of this sort. It's open source. The least they could do is have the decency to advertise the fact that it's a clone (as per your license agreement), but some people are just too greedy.
I'll be buying an original this week.

@ocornet I was watching a youtube video, and someone mentioned that the Duet WiFi was probably the best 3D printer board available, and whilst I was searching for linear rails on Aliexpress for a printer I'm building, I happened upon the 'Duet WiFi', and thought I'd give it a try. I hadn't looked at the price of the original or the clones, and as such, I assumed it was original.

It seems I have accidentally purchased a cloned Duet WiFi and PanelDue 7i from a seller on Aliexpress. The seller didn't state that it was a clone (They have now changed this), so I assumed it was real, especially as it was coming from the 'REPRAP official store'
I contacted the seller, who has since changed the Advert title to include the word 'clone', but my question is this. Do these sellers not have to advertise their clones as clones? Or can they simply wait to catch out unsuspecting buyers, then change their wording to include 'clone'? Is there not some sort of license agreement in place that prevents them from doing this?

This was the original listing.


And the listing with the updated title.
