What is the 'capacitor plague'?

Qidi 'engineering' strikes again: https://www.reddit.com/r/3Dprinting/comments/1jnuju1/rqiditech3d_permanently_banned_me_for_warning/
tl;dr - a Qidi Plus4's SSR (which we have been warning about since day freaking 1) finally blew and caught fire, with serious consequences.
I've said it before and I'll say it again: do not buy Qidi printers, don't suggest others buy Qidi printers. This isn't just sloppy engineering, this is outright dangerous.

Decided to print one of these today. Definitely came out great: combination of the extrusional consistency of ABS and variable layer height really did work here. I scaled up to 150% of the original size, as I found the original too small.

So, not only are Qidi bad at hardware, they're bad at software too: https://github.com/QIDITECH/QIDI_PLUS4/issues/49
Do not buy Qidi printers. Do not encourage others to buy Qidi printers. This is absolutely unacceptable on a printer that costs USD800. The fact that _busywaiting_ can kill the MCU is just beyond absurd.

TIL that I'm out of black ABS. Since Catboat-1 is due upgrades (and a rewiring), I need black ABS.

Paramount3D do not ship free to me anymore. I _love_ how NZ supply chains are a fucking constantly-moving target...

This video, plus its comments, are a perfect demonstration of the Creality Effect (that is, 'issues nobody else has') and why I do not advise buying any printer that they make: https://www.youtube.com/watch?v=udhl2mzfLbc
Even if you ignore the comments, the fact that heatcreep is this much of a problem on such an expensive machine, in _PETG_ of all things, is rather sad, and typical of Creality.

#Resin3DPrinting folks: I'm getting some odd behaviours from my printer (and possibly my wash-and-cure), both of which most clearly manifest on large, flat surfaces. The first is this weird bubbly texture: the print in the image is fully cured and dry to the touch, but the texture persists. The second are these weird small surface lines, parallel to the build plate.
Any help figuring these out would be awesome.

Another LGS request, even larger this time! 5x5x14 units, with a dividable internal box.
The dividers from the original design were too thin and ended up quite bendy, so I improvised.

Once again, Igor from My Tech Fun doing the work: https://www.youtube.com/watch?v=YuLNVoUtaes
tl;dw:
* Bigger objects benefit from this method more than small ones
* Because of the 'shift' induced by the Ten Tech script, you need to bump your EM on the 'shifted' sections or your part gets _weaker_ due to reduced perimeter contact
* Given the above, at least some of the strength increase is attributable to the extra material

Another day, another model badly-designed for #Resin3DPrinting : https://www.myminifactory.com/object/3d-print-space-elf-warmancer-bundle-volume-1-pinups-285250
I'm kind of annoyed actually. This designer does quite good work, and this is the first issue of this kind I've yet had with anything they make. It's also _really_ obvious, and would have been spotted if they did a test print. In fact, one of the _other_ community prints showed this to be an issue ... a year ago.
Glad @npub16gy…kerf triple-checks _all_ her work!

So... I printed the OPR model that gave me so much grief (with some UVTools help). Now begins the #Painting effort.
I tried a slightly different black preshade here. Instead of equal parts Aquadrop and water, I used a ratio of 5:3:2 of Aquadrop, water and flow aid. In retrospect, should have used more flow aid.
Work time is a real challenge for this model due to its size - the hair ended up getting too dry to work.
@npub18cx…wnff - another model to your scale.

So, to my surprise, OPR responded to my complaints, as made here: https://chaos.social/@koz/113865066733839226
Having checked the model just now, the resin traps are gone from the head (although I still feel one of the horn 'tunnels' is questionable), and the base has been oriented to be 6 inch printer friendly (although I would have gone for a less steep angle for less supports). Glad this got done fairly quickly!

I swear to everloving Jeebus, OPR _cannot_ help themselves with the resin traps. This is the _third_ time I have found resin traps in their models, which I might add are being sold for money, with a reputation for prints that 'just work'.
Sigh.

New year, new tuning thread! Today's filament which caught my curiosity is 3DEA's PETG-CF Pro15. This stuff is interesting because, unlike most CF filaments, its carbon fibres are concentrated in its core, leaving an outer jacket of pure material. As if to flex this fact, it is available both in black and in white: I am printing the white today.
This is similar to the techniques used by Essentium for their HTN-CF25, but the CF load is higher.
Let's go!

Because patents are the worst, ZS Plus nozzles are about to vanish. Aliexpress _already_ doesn't have any, and TL's own site has them at half price to clear: https://trianglelab.net/products/zstc-mk8-volcano-v6-zsd-mk8-volcano-v6-zs-mk8-volcano-v6-k1-nozzle
Words cannot express how much I love these nozzles. It's the first high-flow hardened that isn't designed terribly from first principles, and mine has run _spools_ of CF material with hardly a complaint. Get one (or several) while you can.

Back from my holiday, back to the workshop. Pictured: a 96-cell Gridfinity, using bolt-together plates. Also pictured: material creep, which I plan to deal with using reinforcer plates from below.

It has been 0 days since I've had to use Blender to fix a model for printing. This time, it's an extra achievement, because the issue was an FDM model, not a resin one!

Here it is, the biggest single part I've ever printed on my Mono 2. #Resin3DPrinting at these sizes is a challenge all its own, but I'm happy I got something usable in the end.
It will need a bunch of post-processing, and this part isn't done yet, but it's pretty great. The top bit was so large it couldn't fit in my curing station, forcing me to improvise.
