Can you go through the commissioning steps fresh?

Good morning,
No communication after factory reset.
IC's get very hot
-
? ? ? ?
-
going from first principles:
-
hot ICs usually means a short or a voltage regulator died.
-
make sure there are no metallic parts, brass brush bristles, bolts, nuts, or anything else that could be conducting, in contact with the front or back of the board.
-
unplug all wires that go into the toolboard and make sure that all crimps and wires are fine (do a pull test on each wire to ensure the crimps are a) well crimped and b) retained properly in their housing). Side note: Strain relief should be part of any toolboard mount design.
For the next steps you may want to remove the tool board from the printer and place it on a non-conductive surface for testing.
- take photos from the front and back of the tool board. Those photos should be so that the toolboard components are in focus. Share them here.
For the next steps, ensure power to the printer is OFF and all capacitors discharged before working on the wiring. Unplug the printer, and if you have a power button turn it to on. Then wait a minute or thereabouts before working on the wiring. Only switch on again after you have made sure all wires are properly plugged in and nothing is shorting out the board or wires (tools etc. away from the board).
-
connect only power to check whether the VIN and 5V LEDs turn on. If they don't, don't wait for the ICs to get hot, but turn off. If the VIN LED turns on but not 5V, the voltage regulator is blown. This usually happens due to a short.
-
If and only if VIN and 5V LED turn on in the previous check, reconnect CAN wiring and check whether the board is behaving better when nothing is attached to it.
-
if and only if the board is behaving better when nothing is attached to it, re-attach the components one-by-one. Consider grounding the hotend before attaching the heater and thermistor wires.

-
Disconnected everything on the board, power up status led blinking and soon U4 heats up and STATUS led fades out.
Blowing on U4 or a finger (cooling U4) turns the STATUS led on blinking. -
Changed the 5V regulator and it gets hot as well so there is a short somewhere.
-
can you provide hi res photos of front and back of the tool board?

Later perhaps
Ordered a new one from Denmark as I am in need for the board asap.

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.
It's likely the TMC2209 that has failed.
-
Long story short. #1 I never have used the 2209 #2 original purchase from RepRap NL #3 You at Duet sent me the replacement if I recall all correct.
So why would the 2209 be the issue? Is it so that a freewheeling 2209 can not survive?
-
I'm not sure. That was DC42s best guess.

OK, will send email and fill the form.
