Those VzBots with the AWD mod and Goliath Water Cooled hot ends are total beast. I believe there is a video of one printing at 1500mm/s on youtube
edit… found it.

You have to measure that in cores per hour, from a V1 perspective.

I couldn’t imagine being able to print anything like a V1 Core at that speed. But maybe it is possible lol. His model was extremely simple and low lol
I’d say filament technology will have to be developed to cope. Not just flow rates - strength at those rates. Prusa had a nice paper on that a little while ago, and they as well as others have been developing their filament range to deal with it - but you’d have to think there’s a point where it becomes self-defeating.
Also, in a “production” setup, maybe it’s better/easier to have multiple simpler printers that may be a lot slower, but also a lot more reliable, easier to maintain, and a lot cheaper
If I’m making a prototype part and iterate a lot on it, I want a fast printer to speed up the iterations
But if I want to churn out a dozen copy of 4-5 parts (eg. producing the v1 parts for reselling), I’m probably better off with 3 or 4 “slow” printers running in parrallel

For anyone that hasn’t discovered Clickspring on Youtube yet… I leave this as the entry point of the rabbit hole that is his work.

That is the target speed we need to build to. I feel at some point there has to be a significant layer adhesion issue…but then again if you come around fast enough it is still hot and the bond might be better. I have always assumed the bond happened at the initial point of contact though.
I agree here as well, just need to know what the speed it to target for a build. I can not imagine any of those super speeders lasting long. They are like Drag racers to me.

They do rattle stuff loose. 
About 150 to 200mm/s is my printer’s sweet spot for fast. It’ll go faster, but my cooling duct is kinda too heavy for that.

Can you imagine playing a board game at two ends of the room and the board walks over to the person who’s turn it is?

At least then there is no looking into cards etc. playing Settlers of Catan.

did you already start? Nice starting project on a new lowrider…

No, not going to any time soon. He did publish part of the leg design, but there is sooo much else that I’d have to do and learn. Maybe during the next summer.

That thing walks better than I do! Insane!

So LinuxCNC might be available on every distro soon, without mucking with a custom kernel.

I would be so paranoid updating my linuxCNC build, but I might have to try it one of these days when this gets out there. I am pretty sure I just have a config file with most of my settings and the rest is just UI tweaks.
But, I am sure this would make starting fresh much easier.

what board are you using with linuxcnc. When I looked at it when I was starting my cnc journey, it did not look like just any board would work.
Now I need a lathe to turn down brass.

Silly of me to reply since I’m so out of the game at this point but…
Go here and download the Debian 12 Bookworm ISO. This will “install a full Debian system with the required realtime kernel and the linuxcnc-uspace application. It uses a PREEMPT-RT patched kernel which is close to mainstream Linux but does not, in some cases, give quite such good realtime performance as the previous RTAI kernel. It is very often more than good enough. It should probably be the first version tried even if using a parallel port. This is compatible with all Mesa and Pico interface boards.”
I’ve never had difficulty with the LinuxCNC “Live CD” ISO images in the past… just boot it, play with it a bit to insure it seems to runs okay on your hardware, and then click on the install icon. You have opportunity to set it up for dual-booting with your current OS or to be the only OS on the disk. No installing the OS, “mucking” with custom kernels. or installing LinuxCNC… it’s all there: i.e. the Debian OS, the RT kernel, and LinuxCNC itself. There’s even a RaspberryPi version of LinuxCNC.
If you have some Linux experience and a grasp of what you’re trying to do CNC-wise… I doubt it could be easier. I’ve played with the parallel port and RaspberryPi4 GPIO versions of LinuxCNC and even developed a couple of “Inexpensive LinuxCNC Interfaces” for it, i.e. parallel port and RPi4 GPIO. I’ve not played with the Mesa and Pico interface boards… but I suspect they are definitely the way to go for anyone somewhat serious about it.
I’ll shut up now… just my $0.02.

Reminded me of the Luggage from the disk world novels. Amazing work.
