Duet 2 Wifi - VIN led only

What's going on here?

Can you route that red wire (MOSFET control?) so it doesn't seem to potentially hit the reset button?

TimsWorkshop

@oliof Yeah I can, but even with this moved, the unit is responding.

oliof

does it behave better when you disconnect the heater?

TimsWorkshop

@oliof unfortunately not.. I've got everything disconnected from the board besides the power.

TimsWorkshop

For my own sanity... if PSU powers up, mosfett works, and VIN LED comes on... can I safely assume all the wiring, crimps, and ferrules are done correctly?

oliof

5V and 3.3V LEDs should also light up.

TimsWorkshop

@oliof so as I search here and Google more, lots of posts around the 'fuse', so while I think the Fuse is ok... I am no expert and Googled how to check if a Fuse is blown and I think maybe my 7.5 fuse is?

Here's some photos of the fuses.

Labelled 15 (looks OK):

Labelled 7.5 (looks disconnected, blown?):

Grey Fuse, not labelled (can't tell if blown or not):

The red Fuse seems as it's blown

@siam Thanks mate, I got some different photos and I agree, both the red and grey seem blown

There's a local electrical store, but when I search 7.5 fuse, I get this: https://www.jaycar.com.au/search?text=7.5+fuse&CSRFToken=46ea0ec5-643e-47f9-8b01-1b49191b44f4

Is there specific fuses I should be looking for?

SIam

@infidelprops Yes both fuses are dead

There's a local electrical store, but when I search 7.5 fuse, I get this: https://www.jaycar.com.au/search?text=7.5+fuse&CSRFToken=46ea0ec5-643e-47f9-8b01-1b49191b44f4

These are the right one

normally you will get this fuses in a car equipment shop

UPDATE: Before you insert the new fuses check every Connection it seems you have somewhere a Problem with your wiring

Phaedrux

If you have a multimeter you should check the fuses for continuity. I can be difficult to determine if they are for sure blown visually.

If you don't have a multimeter... how did you get this far building a printer?!

TimsWorkshop

@phaedrux haha, I do have a multimeter and will check those now as well.

TimsWorkshop

@siam Agreed mate, I'm going to re-cut and crimp all my power cables this morning.

TimsWorkshop

Just picked up new fuses and put them in... she's alive!

Now to re-do all my cables
