elucubra

I have some money in Rocket Lab, and Planet Labs (I like space stocks). Yesterday, comparing both, I saw that they have very similar curves. I checked a space ETF (Vaneck), and it was markedly different.

What surprises me is that while both are space stocks, their core business is markedly different.

Am I seeing major manipulation here?

I have the nagging feeling that a major player is doing manipulation here. Elon, screwing competitors, maybe?

A duck swims, then climbs a rock, then walks, then he lounges for a while, then runs, then swims again, then dives, and suddenly remembers some time ago he heard about another continent, so he takes off, and flies for days, only stopping to eat and sleep. Yeah, I'm a duck.

Are there some hidden gem or outstanding value cards out there in the sub 200€ range? Used, if they blow out of the water some newer ones for the price, are OK.

What distros do you install on your mom's, sister's, buddy's, etc machines?

My go-to has usually been Mint, but I wonder if there is a better set and forget, easily understood distro to install on the computers of those who will rely on you for support.

atomic distros would probably be a good option, but it seems that same disk dual boot is a no no, and that can be a deal breaker.

I'm thinlink QoL, for me, that is.

Has anyone run two nema dual shaft motors mechanically coupled in series? the Ender 5 plus uses a dual shaft to drive both Y axes, and I'm thinking of adding another, in series, coupled with an elastic coupler.

Thoughts?

Every morning I spend 12 seconds making a ranked list of priorities for my day so that I can hyper focus on something else.

Most of the multi color printers out there are AMS/MMU or similar, and there are many DIY options, like Armored Turtle or ECF.

They are an evolutionary dead end. Slow, wasteful, expensive to run.

The Prusa XL, or the Snapmaker U1 are the future direction.

Also a good CoreXY machine like vorons/sovols/ratrigs/VZ, etc can be upgraded with the Bondtech INDX tool changer.

We are talking 5x lower print times, 5x lower material costs.

There is going to be a glut of used Bambus and other multi material unit printers, when print farms unload them, since the tool changers will massively boost their bottom line.

Comments?

I know that many mods for some printers aim to enlarge the volume, but I've been considering downsizing somewhat my plus, as I have moved to a smaller house and the plus is a bit too large. An option would be to trade for a regular Ender 5, but I have had one, and the plus is better in many respects. Just the 4 guide/2 bed screws put it in a different league.

I really like the plus, I have modded it (hotend, direct drive, Klipper, board...), and have it pretty well dialed in, and I'm going to convert to "CoreX", a cheaper hybrid alternative to CoreXY, that removes a lot of weight from the gantry, ergo, higher speed and accuracy.

I'm going to end up with a respectably fast and accurate single color printer, and I'm considering adding the INDX tool changer.

I have googled, but either my Google-fu fails me or it's just too obscure of a subject.

Has anyone seen something like this?

I'm installing a second disk in my desktop, and I'm going to install Linux.

I've had dual boot on all my machines since forever. As in decades. I'm an old hand. Perfectly happy in a terminal.

I have Mint in (on?) my laptop because lazy.

I'm asking about QOL. The only "Gaming" I do are flight Sims, and although I haven't tried, I believe X-plane is Linux native. However, I do use some apps which are not Linux native, so I'd need some form of wine or performant VMs.

The PC is a Ryzen 9+64Gb, so it should handle a lot of things quite well.

I've been playing with both in VMs, but I can't get a feel for what my virtualization and wine use would be.

BTW, I might do an install of both, maybe side to side, without commitment to either, and then decide. It's going to be a blank slate install anyway.

From my trials, both seem comfortable enough.

I've heard good things about both.

Opinions?

When querying AI, end the query with "provide verifiable citations". It often vastly reduces the bullshit.

No affiliation or anything. I’m simply stoked!

Elegoo Rapid PETG. I like PETG, but with my printer (Ender 5 Plus, slightly tuned; DD, All metal hotend, dual gear extruder, accelerometer…) regular PETG is sloooow. I’m already up to 180 mm/s it prints beautifully. As with all PETG it likes to be thoroughly dry. Once dry it prints like a PLA+. Beautiful definition.

I paid about 15€ per roll, but buying a 4 pack, it comes to about 12,50€ per roll, so about the same as PLA.

I’m just not buying regular PLA, or PETG anymore. The new generation of materials just leave the older ones in the dust. I had a few rolls of standard PETG that I had slowly been using up, but I sold the last 2, I couldn’t bear the waiting times.

I’m going to try a bunch of the new modified materials, like ABS plus and HT, ASA plus, and especially Polymaker’s HT-PLA-GF, a glass fiber high temp PLA that can be annealed in boiling water without deformation to withstand temps like 150º. Nuts! They are basically sold out until August, but once back in stock I’m buying the stuff.

Interesting times to be in the hobby.
