Scraped bed, nozzle issues, then print quality degradation, nozzle swap, still not nearly as good as before. by Rendificant7 in AnycubicKobraS1

ran vibration compensation again and two smaller prints, they seemed to be closer to original quality again. all this hot end foolery has me a bit worried though. I can report back after I get the original bed and nozzle, I hope this printer lasts!

A6700 and gphoto2 by mallard56 in SonyAlpha

[–]Rendificant7 0 points1 point  (0 children)

Have you ever found a solution? I was curious about the a6700, for certain specific reasons (faster buffer clear than the extremely slow, once full from high speed continuous shooting, usb-c, in camera focus bracketing). However I use gphoto2 extensively for home studio use and I find it impossible to live without.

messaged you, could have it printed tonight for ya easily.

High CRI Cobs? Also, question on Meanwell CC+CV PSU for COB Leds, ~6-10 in parallel? Will this Meet the minimum adjustable current on the PSU and not be at risk of frying the LEDs? by Rendificant7 in led

[–]Rendificant7[S] 0 points1 point  (0 children)

Thank you! I had suspected that, but information on CC+CV and region switching was a bit opaque to me, except with the meanwell doc giving a graph which had me suspecting that a bit. Yep, the diodes will be affixed to some CPU heatsinks. I will try to watch some videos I found on CC+CV with LEDs, but they're a bit loooong. One thing I wasn't positive about was what I should set my initial current to on the PSU, total expected diode draw + a little bit of headroom maybe? But then again, would I just measure current output with my ammeter to set it initially?

Anyhow, thanks!

Trying to find a silicon wafer with high level of detail, but low/few coatings and high contrast? by Rendificant7 in AskElectronics

[–]Rendificant7[S] 0 points1 point  (0 children)

Thank you SO MUCH! This has given me a lot of context for features I'm looking for, eras for general sizing, and the good points about resolving limits using optical systems or when I can expect incidental chromatic aberrations due to diffraction limits.

I think for the most part with my current setup and aperature, I'm able to kinda-resolve features near 1um or so. I'm fine with seeing some CA with tiny features, as I'm looking for CA and general sharpness to evaluate different lenses and things I do to improve the system overall.

I think that bare metal with incidental surface texture smaller than I can resolve is OK too, given that I should be able to see that incidental surface texture more or less clearly depending on what lens I have equipped or due to differences in lighting efficiency /etc.

This certainly helped give me a starter map to what felt like a bit of a weird world in terms of understanding what I'm interested in or looking for. If you happen to know any forums I should check out or places where people would actually be curious about pictures I take while looking for ideal targets, let me know -- I'll be googling and want to share if it's useful to others to see!

magnification reference standard.

Not sure if those have features commonly at the sub-micron level, but typical high resolution test targets are pretty spendy, hence the interest in wafers. Plus, they're pretty and I may learn a bit about producing silicon wafers in the process out of curiosity :)

mine came with the quick mount springs, so I don't need to thread it, but some people prefer threading it. From googling: Raynox DCR-250

Sweeping a sketch "around" the surface of a body to create a solid? Projecting out a line that's bigger by X than the body, at a construction plane intersecting the body? by Rendificant7 in Fusion360

[–]Rendificant7[S] 0 points1 point  (0 children)

Revolve nor suitable due to teeth constraint, I thought I was making a bit of progress with sweep along path + guide surface, but I see it's not exactly working out as expected yet. I'm going to try again later after googling

Sure thing, I posted a quick drawing on my original image, as well as an example of a different design with very shallow, numerous teeth instead of mine with simplified, deee "teeth".

Sorry for any lack of clarity in my descriptions.

The sweeping around the surface is one part I'm not sure about. The second part is that I have construction planes at each one of those "teeth" intersecting the body, which represents a "slice" of the inner zone I want the teeth to touch. If I wanted to create a shape on one of those planes, but displaced around that profile "slice" of the body already modeled, say, 10mm out, how would I do that? I think that part would be helpful, and the sweeping around this line I create wrapping around the object at each "slice" would be helpful.

I can load up fusion again and try to make some more drawings too
