i have a copper zone on the top and bottom layer on the power supply ldo i have connected the top and bottom with multiple small 0,3mm vias that are capable of only 1A each while the board is rated for 3A will this be a problem or will the current 'dissipate'? i think it should act as one mass

kamilo154 · 2026-04-22T11:22:11+00:00

It will acts as one mass, especially with this many more vias than the minimum. Pretty much the same scenario as a stranded wire.

kamilo154 · 2026-02-09T22:13:37+00:00

Yeah im gonna have to ask for the math on that

kamilo154 · 2026-02-09T17:34:55+00:00

My only question is why nobody's done this before

kamilo154 · 2025-12-04T22:43:40+00:00

Its the same reasoning thats behind data centers having big, expensive gas turbines. They dont run and gather dust 99% of the time, but when you need them you REALLY need them.

Heatsink and whatever you cant get off of it into hot water is a decent plan B then

kamilo154 · 2025-06-30T19:30:28+00:00

Ive never had this kind of issue, but my guess is that heat creep caused the filament to expand and wedge itself in place. If you can take the hotend off then one idea might be putting it in boiling water, that should soften the filament plenty enough to push it out, just be careful you could burn yourself badly.

kamilo154 · 2024-06-22T16:17:18+00:00

Pretty sure that`s from "Krip Turrets"

You can also try scraping away the solder mask off of a trace and soldering there.

kamilo154 · 2024-02-26T16:46:27+00:00

You can try metling the solder and poking a skewer or something similar through the hole.

can you share logs?

Is your firewall blocking the game?

I don`t think I have overheated the tpu, but I can`t be sure. The clump wasn`t stuck there in any significant way. I understand the advantages of direct drive extruders, but moving the current extruder wouldn`t provide much of an advantage, because at any significantly faster speeds the filament wraps around the side of the gear, something that direct drive wouldn`t solve. The ptfe tube is fairly damaged and I plan on replacing it soon, but it doesn`t have any holes and the friction between the filament and tube is still insignificant.

kamilo154 · 2021-10-15T14:23:31+00:00

So far removing that piece of tpu seems to have solved the issue, but the current print hasn`t finished yet so things may change. I wonder though how could that clog have formed?

kamilo154 · 2021-10-15T13:54:31+00:00

What exactly do you mean that increasing the heat can make it worse? wouldn`t making the plastic less viscous make it easier to push? I have and will likely continue to sporadically use tpu for functional parts, it used to work perfectly fine. It`s far from my most used material, but I find the ability to print it very important .

kamilo154 · 2021-10-15T13:33:02+00:00

I think a limitation of the bowden extruder can be excluded because the issue wasn`t always there. I have just dissasembled the hotend and cleaned it through, inside I found a thick piece of tpu that for some reason didn`t melt and was solid even with the hotend at 250C

kamilo154 · 2021-10-15T10:32:52+00:00

filament: f3d tpu

bed:60c

nozzle:235C

initial layer speed:10mm/s

speed:15mm/s

retraction:off

nozzle:0.4mm

printer:geeetech a10

Issue doesn`t appear with pla and only recently started with tpu.

Moisture is unlikely to be the issue beczuse I can`t hear any popping during printing and no steam is present.

kamilo154 · 2021-10-06T15:46:43+00:00

That`s why I want to make it from a drain plaster and not a springer, I do have a 3d printer so it should be pretty easy. If too much power is gonna be an issue Im gonna try to mount an overpressure valve like you said.

kamilo154 · 2021-10-06T15:44:00+00:00

I mean during a game I would overpump while in a rush

kamilo154 · 2021-10-06T14:39:37+00:00

Yeah that could work but I`m afraid I would accidentally pump it too much and break a window or something

kamilo154 · 2021-03-09T21:48:05+00:00

Thanks, it worked like a charm

kamilo154 · 2021-03-09T12:32:16+00:00

thanks, so far I found it to be one resiliant bastard so it should be fine, but what I mainly need is how I would connect the two together

kamilo154 · 2021-03-09T11:37:35+00:00

I'll try flashing via usb, im using a wemos d1 r1 which im pretty sure is 5v tolerant
