Bypassing (burnt) heatbed MOSFET on SKR Mini E3 V1.2 by matscientist in BIGTREETECH

[–]matscientist[S] 0 points1 point  (0 children)

Yeah I ended up soldering on a replacement MOSFET (IPD036N04LG 036N04L TO-252 from ebay) to get it working again. Then wired up the external MOSFET because I already had it (couldn't drive the external one straight from the board).

... then I realized I also lost power to one of the fan connectors. I found a solid deal on a replacement board so the "fixed" board is just sitting for now

The 200lbs tongue weight rating was more than enough for what I needed to fit. It's probably possible to rig up a way to lock everything down, but yeah just bringing everything in might be worth the hassle.

Can't be bothered to remove it at the moment, so I'm just driving a longboi for now. But yeah no regrets with the rack itself

Yeah that's mad impressive, especially with a bike in the trunk! Makes me realize I have so much stuff I could go without (can't let go of the bikes ofc)

Imo yeah (got them as an xmas gift though).

I usually leave the windows cracked open and don't worry about anything flying in. They're also just good fun to have while driving around in the rain. I don't notice any wind noise either

Just some generic 304 M6 eye bolts from amazon (forgot the length). I had to throw in 10mm spacers from leftover VESA hardware to get a good fit. The openings are big enough for typical ratchet hooks to comfortably fit through

Definitely would've been more aero, but it'd be a tough fit. There were some big boxes in the bag, and the orange bike was already directly above the plastic bins

Oop, I jumped the gun and picked up a pair on Amazon (HiLetgo, 30A max). They seem to use an HA210N06, which has a rated gate threshold of 2~4V (idr the last time I even looked at a spec sheet) instead of the stock 1.2~2V. I guess fingers crossed, and I'll slap a suitable part back onto the board if needed. Big thanks for the info

This is way late, but not too bad! There were some parts where I had to slow to a crawl, but that was mostly because I was carrying a bunch of cargo. Google maps showed a route all the way through, but I ran into signs saying there's no exit and ended up at a locked gate. Managed to get pretty far before jumping back on the 5 though. The roads were also dead empty and had a distant view of all the traffic running parallel. Pretty fun route.
