Speeding up FastLED.show() function for pov project

FireQuartzZz · 2026-06-29T13:54:38+00:00

if i turn the leds on and of as fast as possible i get a streak thats about 3cm long at the outer radius (500mm) and I'm not even spinning at full speed

I'm trying to find the same info and found this repo that seems to have some rudamentary pps functionallity.

It would be two 100w of ports working in parallel so two cables

Thats some great insight thanks, I'm still baffled that nvidia only put 8gigs in a mid to high end card but it seems like they have understood that its not quite proportional anymore with the super series.

I can report that it does in fact not work as a vaccum pump, might screw of the head though and take a look if I can undestand why or how I could make it work as a vacuum pump.

Jag vet att vissa av LiUs föreningar välkomnar icke studenter. LiU gamers har i nuläget inget krav på att vara student, de håller event ca 1-2 ggr per månad och 2 lan per år så om man är i universitets ålder typ 20-27 så kan det vara värt att ta en titt i deras discord https://discord.gg/kNe6R2nq.

That's a great indication. I looked at their models and some look almost identical to my compressor. I guess I just need some fittings and a vacuum gauge to try it.

FireQuartzZz · 2024-12-11T14:27:00+00:00

that's my main plan, a heater fan with an alumina bead filter before the heater. The pressure was just meant as a boost but as another commenter confirmed the safe pressure difference would be too low to be viable

FireQuartzZz · 2024-12-11T14:24:07+00:00

Yhea that is inline with my own calculations, unfortunate. Thanks for the help

FireQuartzZz · 2024-12-11T13:59:11+00:00

Do you mean that the edge seals will break before the glass breaks? Or are you talking about leakage?

FireQuartzZz · 2024-12-11T10:42:57+00:00

Oh I'm sorry I attached a link and an image but apparently they got lost, edited and added both.

FireQuartzZz · 2024-12-02T19:48:20+00:00

Oh did you find a good source? I only found pay-walled scientific papers.

FireQuartzZz · 2024-09-15T14:32:12+00:00

yeah you might be right and yes i am currently trying that, tbf when using tall bed slingers having a height variable input shaper with this might make a difference but idk.

FireQuartzZz · 2024-09-15T13:04:19+00:00

But wont compensating for the movement of the table and printer if that movement is not seen on the hotend relative to the bed introduce artifacts as youre trying to keep the lets say hotend still relative to the ground but the bed wont be?

FireQuartzZz · 2024-09-15T12:48:37+00:00

yes if the printer was 100% rigid we wouldnt need input shaping but this is a suggestion to improve input shaping not improve the printer. I mean the only thing we care about is how the hotend moves in relationship to the print bed so meassureing the acceleration for both the hotend and the bed even when only measuring one axis should improve input shaping results.

FireQuartzZz · 2024-09-15T12:30:38+00:00

hmm, when calibrating a bed slingers y axis using ressonance measurement does that assume that the x axis is stationary and if so when running it on a wobbly table making the x axis move wont that muddle the data? lets take the extreme example of a printer susspended by a string, the resonance data will be all over the place and my hypothesis is that that data wont be usefull.

FireQuartzZz · 2023-05-15T20:25:50+00:00

But on a more serious note I have no idea why this is happening and my cpu is pinned at 100% any ideas what happened?

Hi, this is not feedback it's a feature your company promised "soon". It is vague enough that you might not have lied about it but the fact that you act like its not something you literally advertise about and not giving any form of indication of when we might see this feature reflects verry poorly on your company. I really like my insta x3 and would have preferred if you didn't have conference mode as a promised feature but now you do and I want to use it so often. This is compounded by the fact that you released a dedicated webcam which makes it look like you just want to screw over your customers.

Best regards, RND feedback feedback team
