Heater and fans not working.

droftarts

@tecno okay… just to check your config, and double check it’s not turning on:

M950 F0 C"out5" Q500 ; create fan 0 on pin out5 and set its frequency
M106 P0 S0 H-1 ; set fan 0 value. Thermostatic control is turned off
M950 F1 C"out6" Q500 ; create fan 1 on pin out6 and set its frequency
M106 P1 S1 H1 T45 ; set fan 1 value. Thermostatic control is turned on

Fan 0 on Out5 is configured off at startup. Fan 1 is configured to turn on with heater H1, when it gets to 45C. You haven’t included tool definition, so just in case you have bound the fans to tool 0, send T0 (or whichever tool the are bound to) then send M106 P0 S1 H-1 and
M106 P1 S1 H-1. Both fans should turn on full.

No luck, fans are dead

Looks like I have received a DOA board delivery

Does there appear to be any visible damage to the fan mosfets?

Would you be able to test the mosfets with a multimeter?

And just in case, have you confirmed that the fans themselves are working by connecting them to an always on fan header?

@phaedrux
As I wrote earlier no visible damage and fans verified with 24V
Yes, advise how
There is only 2 fan headers and both are dead.

@tecno, please can you post a close-up photo of those two fan mosfets.

What revision number is the board? It's printed on the underside.

@dc42

Hope these photos are OK so you get the info you need.

@tecno that’s perfect, thanks. I approve a warranty replacement. Please contact the seller and follow their warranty process, quoting this thread as authorisation. Apologies for the inconvenience.

How is it revision 1? Bart only has V0.5 in stock!

droftarts

@tecno how is what revision 1? You have a revision v0.5 board, as it shows in your photos. There’s only tiny differences between v0.5 and v1, mainly to aid manufacturing; see https://duet3d.dozuki.com/Wiki/Duet_3_Mini_5plus_Hardware_overview#Section_Revision_1_Num_0
I guess RepRapWorld are still selling slightly older stock, which is fine.

This does not appear to be a valid Duet3D Warranty Authorisation Code

@tecno oops, sorry, we’ve just changed how we do warranty authorisation.

Please send an email to warranty@duet3d.com and CC your reseller. Include a link to this forum thread and the details of your original purchase. You'll receive a reply with a form to fill out and warranty authorisation code.

@droftarts

Already filled the form without WAC (omitted the code so I could fill the rest) and cc to Bart.

So I think you can fill the blanks inhouse.

Yes, no problem.
