Posted · Ultimaker original 3 fans circuit wiring

I have an ultimaker original with the green circuit board, cant find anything online about the original board.

I purchased an E3D v6 hotend, which has 3 fans, 2 side mount 12v fans, that ive wired in parallel into the old cooling fan spot. But the third fan is a central mount that always needs to be on (like the UM2), its 12v 0.1a, i tried wiring it in parallel into the ultimaker board cooling fan, which worked for a while but now has stopped working.

Ive taken it out and it runs fine from an external power supply so the fan is not broken, just probably not getting enough power, where else on the board could i wire this into so that it can get enough power without messing with anything else??

keep in mind this fan has to always be on, so it cant be pulsed. but if on a control setting i could alter the firmware for that could work too.

Btw i also have the heated bed upgrade installed, but everything else is stock.

    Uh yes... The old Ultimaker board... A bit of a hassle that one... You are indeed correct that you just need a steady supply of 12V for that heatsink cooling fan, did you look everywhere on the board for something like that? (I don't have my old board anymore, but seem to remember (and can see from pictures online) that there are quite a lot of unused pins on the board with various labels like "LED" and even "12V OUTPUT" (at the far end from the switch).

    Do you per-chance have a multimeter so you can do some measurements on the board?

    You mention the heatbed upgrade kit, how does that work again? Does it run off the same power supply as the UM and at 18V?
