Duet 2 Wifi doesn't turn on when connected to 24v psu

dc42

@braeden it's a clone Duet so that green LED is actually the VIN LED.

Looks like either the 5V_INT jumper isn't fitted (although it looks fitted in your photo), or the 5V regulator isn't working, or something is shorting 5V to ground.

Braeden

@dc42 Is there anything I can do to fix it?

alankilian

@braeden Wiggle the 5 Volt jumper or try removing it and shorting the two pins with a paperclip to see if your jumper is bad (unlikely)

Other than that, you can work through this schematic and see what's wrong with the 5 Volt power supply.

Or you can just add a 5 Volt power supply to your system and insert the 5 Volt as an external supply and move on to printing!

Braeden

@alankilian I’ll take a closer look and see what I can figure out when I get back home! Thank you! I was just thinking about adding an external 5v to see if that would get it working.

Braeden

@alankilian Alrighty so I got everything wired back up with the jumper on the ext 5v pins and I have 5v being supplied externally with a step down converter however when I try to home the X axis I get the same error “Attempt to move motors when VIN is not in range” as if it were still plugged into a USB port and also the E0 heater is not heating.

Is the VIN LED illuminated?

Braeden

@phaedrux Yes

Phaedrux

Can you measure the VIN terminals at the board with a multimeter to ensure there's correct voltage there?

Can you share the results of M122?

Braeden

@phaedrux I received 24v when I measured the vin

Absolutely!

Can you pull the blade fuses and test them for continuity?

alankilian

@braeden

The Duet power supply voltage sensing is not working properly:

Supply voltage: min 1.5, current 1.8, max 1.8

Can you check the voltage between ground and L5/C64?
You should read 3.3 Volts on each side of L5.
This is the reference voltage for the Analog converters.

Also the voltage at the connection of R80/R81 and R16/R15 (Shown in the schematic above)

You should read..... (Math.....) (4.7/(4.7+47))*24 About 2.2 Volts

Braeden

@phaedrux The 7.5 fuse is blown. The other 2 are fine

Braeden

@phaedrux Replaced the fuse and now it’s working!!! Thank you!!

NICE!

Braeden

@alankilian To confirm I was able to replace the fuse and switch from the external 5v back to jumping the pins for using the internal 5v converter without getting any errors. Thanks to everyone that helped!!
