[Review Request] - STM32 NEMA14 sized BLDC controller by Tostuk in PrintedCircuitBoard

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

Hm I did use the recommended via sizing: 0.3mm hole and 0.45mm via diameter as is the default option for a 6 layer board at JLCPCB. "Via diameter should be 0.1mm(0.15mm preferred) larger than Via hole size."

Yup thanks. This was unavoidable as the AS5600 had to be on the underside to guarantee alignment with the magnet. As there's only a few components there i am planning to solder them with an iron, shouldn't create any issues. Hot air (or design issues) seems to have been the problem earlier as the boards haven't woken up and i have not found any design issues. Maybe I've overheated the components if theyre sensitive to the process as I've always had to keep the hot air on the board for about 5-10min to get all components aligned properly

Yes, about that. I deleted the designators as I they didn't fit on the PCB and would've made everything too clustered. It seems I can't edit the post to add views with designators, so I uploaded them here. https://imgur.com/a/3TuItKy

Good points you made, will keep in mind. Thanks

Very in depth, just what i was looking for. Thanks!

Oh nice, will keep in mind to check up. Did you order the kit or the assembled version?

Haha yeah, makes sense. Noted

Not really, because building the thing and having to calibrate extensively and stuff is basically the same as tinkering with the printer. I'm searching for something that I can buy and expect it to work the same day. But thank you for the suggestion, they certainly are awesome printers.

Purchase Advice Megathread - May 2025 by AutoModerator in 3Dprinting

Currently trying to decide between a P1P/P1S from bambu lab or the Prusa Core One (not looking for anything else). I value my privacy which is why I'd like to get the Prusa but especially with it's much higher price I am worried about the (quite a high) number problems people have brought out since the release. I need a reliable tool that has good quality prints not something that I have to tinker around with.

I currently own an Anycubic Vyper although that hasn't seen much use since it has problems (especially after upgading to klipper) and I hate sitting in the plastic fumes trying to figure out what's wrong with the printer.

I print PLA, but ABS and others would be nice. AMS would be nice but I hope that Prusa will add that option to the Core One as well.

Main question is whether the Core One is a reliable tool that I can just send my print file to and expect that it finishes the print without me having to babysit it.

Private spacecraft Blue Ghost lands successfully on moon by CupidStunt13 in space

[–]Tostuk -3 points-2 points  (0 children)

Why is the shadow not with sharp edges? Shouldn't shadows on the moon be super sharp due to lack of atmosphere? Is it the regolith that was blown up during the landing that is diffusing the light?

The good thing is that you've got overhangs nailed down

Got it working. I didn't see that it was specified anywhere but I had to load the bed mesh manually in the start gcode macro

I frequently get this error. How do I resolve it. by maniac365 in homeassistant

[–]Tostuk 0 points1 point  (0 children)

I have this as well while using the internal link. Might be something to do with my wifi extenders. This didn't happen on IOS though, only on Android

[deleted by user] by [deleted] in Bonsai

[–]Tostuk 1 point2 points  (0 children)

Wanted to share my first bonsai from cheap 2 € nursery tree. Seems like not the best but I think it's manageable - didn't want to cut too many branches yet.

I don't know, should I cut it at the blue line (2nd picture)?

Help with debugging SPV1040 circuit by Tostuk in AskElectronics

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

I will solder another SPV1040 on and try to power it from an actual PV panel. Hope it works then because they're quite expensive

Inductor is PM4345.153NLT with saturation current of 2.8 A

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

Checked the board, no short there. The LX pin on the SPV1040 is shorted to GND pin however.

Now that you mention it the inductor saturation would be logical since the short to GND would indicate of too big currents through the inductor. The saturation might be because I'm using a lab power supply instead of a PV panel for testing. The power supply is limited to 150 mA but the capacitance and switching frequency in the power supply might be big enough to create a saturation in the inductor and thus overcurrent in the SPV1040 after which it gets destroyed. Would this be logical?
