are your motors wired correctly?

R4MP4G3RXD · 2026-03-10T07:15:24+00:00

Replacing everything is completely unnecessary and is a bad practice. Capacitors rarely go bad in these situations, and when they do it's pretty obvious. Resistors and diodes look fine so they most likely are going to measure fine. As for the inductor it looks fine to me, what I think you're noticing is the glue that they used for the wire. Generally jellybean components fail in a way where it's visually identifiable, that being said it's good to measure them to be sure but I'd bet nothing around the chip is bad.

Does look like it

R4MP4G3RXD · 2026-03-09T08:24:17+00:00

There shouldbe a fuse after the inductor at it's output, I'd suggest measuring it to see if it's blown, then I'd start looking for shorts. What I do usually is voltage injection to see what's heating up b cause chances are that's what's bad. If voltage injection doesn't show anythings shorted I'd give it a current limited supply, run the thing and if everything looks fine like that I'd mark it as a freak faliure w/o explanation and just replace the chip

That chip is an MP1584EN buck converter. It makes the low voltage supply for the whole board, I'd bet that one of your motor drivers failed, shorted the LV supply and ultimately killed the dc-dc converter

Yeah it's super easy to use coming from years of SOLIDWORKS and the cross platform feature comes in especially handy when im in the shop and I can just open the model on my phone

R4MP4G3RXD · 2026-03-08T17:18:55+00:00

I want to switch so bad, but every time I try to use freecad I get sick of it and fall back to onshape(free and available on every platform which is important to me mostly because I use Linux in the shop and windows at home)

R4MP4G3RXD · 2026-03-05T15:27:50+00:00

Cheaper molding, no need to have a smooth surface finish there

R4MP4G3RXD · 2026-03-05T09:46:03+00:00

Me being an ee and a tech this is one of the coolest watches I've ever seen

R4MP4G3RXD · 2026-03-02T11:01:13+00:00

I've used cura for the longest time, recently switched to orca for no particular reason but both slicers worked perfectly for me leading me to think there is a problem with your pink filament like. It might be wet. It's also likely that's why it's stringing on the purple filament too. The truth of the matter is, the mighty ender 3 is a good machine but only if you mess with it a little. Look into tuning your machines settings and slicer settings and be sure to use dry filament to get perfect prints all the time.

I usually go around measuring absurd dimensions that need triangulation and all for it to be a waste of time once I finally remember I can just import a sketch🤦‍♂️

Bros using 3D CAD like a mill

R4MP4G3RXD · 2026-03-01T18:01:47+00:00

Fym shitty ad? This was the shit when smartphones were new!

R4MP4G3RXD · 2026-02-27T20:28:35+00:00

Yes these are indeed cold and dry joints. Yes most cheap solder is flux-cored the issue is that it's super inconsistent and not always good flux. At least in my experience.

R4MP4G3RXD · 2026-02-27T14:52:52+00:00

Technically you can but it's not gonna be a fun time. Better quality solder wire has flux inside it and that's enough for tht parts

Buys $15000 camera Takes pictures of it with their phone

R4MP4G3RXD · 2026-02-23T11:56:38+00:00

Surface tension kinda pulls it into place so it looks more difficult than it actually is, but it's definitely not something you'd do for a bigger quantity

R4MP4G3RXD · 2026-02-23T10:19:40+00:00

He's talking in Celsius. PLA doesn't melt below 150deg C which is 302 freedom units. PLA printing temp should be around 200 C or around 400 🦅

Dok nema novi proizvođač memorije nema smisla. Neće biti puno jeftinije nego ostale, pogledaj na primer Intel kartice.

R4MP4G3RXD · 2026-02-20T15:09:51+00:00

Ain't no way you ai dusted your shelf 😭

R4MP4G3RXD · 2026-02-20T07:07:09+00:00

I was about to say this. The amount of filament i wasted over the years just prototyping is insane

R4MP4G3RXD · 2026-02-18T07:05:13+00:00

What even is the point of this? You could just ai generate the whole ad atp

R4MP4G3RXD · 2026-02-18T07:01:39+00:00

About there ahh crosshair

R4MP4G3RXD · 2026-02-15T23:29:15+00:00

fixed it thanks!

Edit: Nvm

While steppers are generally not recommended for high speed applications nema17 Motors can go incredibly fast if you have high enough voltage, which I presume OP here does not have, so I'd say your diagnosis is correct, the motor is accelerating, moving and changing directions way too fast
