- RocketKossel delivers again! I recently cut my carriage mass from 78 to 46g per tower with 9C rails and upgraded to 24V to drive the steppers, plus upgraded to RRF 3 for input shaping, so it's time to start exploring the new limits...
Speedboat biz:
Time 7:36:06
Sliced per speedboat rules, .4mm nozzle and .4mm line width (.5mm line width for top/bottom), .25mm layers, 10% infill in 0.5mm layers, 2 perimeters, 3 top/bottom layers.
Hatchbox blue PLA, 230C on 60C bed.
Sliced in Cura 5.0.0
150mm/s Infill and 260mm/s Walls/Top/Bottom and 500 Travels at 33k x 40 jerk, 150 x 10k x 40 initial layer speed with 200 x 20k x 40 Travels. No retractions, no PA, MZV @ 57 hz enabled.
Main printer specs:
12V PSU for cooling/bed and 24V for Board/steppers/hot end
Bondtech LGX Extruder (flying)
Metaform Pico Hybrid hot end + custom KapWaffle sock
SeeMeCNC aluminum barbells + Trick Laser Arms
Wantai 0.9 steppers (42BYGHM810)
Duet2 Wifi running RRF 3.4.1
Capricorn bowden
SEBS9 rails with 9C carriages
Anycubic Linear Kossel XL extrusions and bed
RobotDigg aluminum corners
ROCKETKOSSEL printed frame bracing, moving parts, etc. (mine, unreleased) with 46g moving mass per tower and 78g effector and remote cooling
Salvaged Shark SV780 dust buster impeller + MKS MOSFET for layer cooling
Vision Miner NanoPolymer bed adhesive

I applaud you for your cell phone
The flip phone is the best !! 🤣🤣 but seriously that printer is on fire 🔥!
Haha, thanks! Flip phones 4eva!
Seriously impressive stuff! If I can get a benchy in 1/3 the speed on the Phoenix I will be impressed, this is next level!
You'll get there, I'm sure of it!
Please try ABS.. PLA is so hard to do this in that time with quality! Nice machine!
Thanks! It's way past the Pico's flow rate with any material ... I will be back when I've solved that :D
Great speedrun! Have you considered adding a direct drive sherpa or Orbiter? It may add a bit of mass but with higher voltage motor drivers it could push the speed further with finer filament control. Great work as always James!
Thanks! I am not considering DD for this machine. I'm already up against the flow rate limits of the hot end. I might eventually play with remote drive again (e.g., Nimble) if I can fab a hardshaft replacement for the cable drive.
... Although on further consideration, I can get more flow out of this hot end by just upping the temp ... I can get another 10C with this nozzle (PTFE lined) before I'd have to swap to an all-metal nozzle, but the downside there is that the all-metal is hardened steel and that doesn't conduct as well as brass, so I'd be taking a flow penalty for the option of exploring how PLA prints over 240C. I have tons of speed and accel overhead, and plenty of cooling overhead as well, so it really all comes down to how fast I can get the Pico to whizz out plastic -- that sets the speed limit. And since there's some Ender 3 out there that managed a 6:41 printing PLA through a volcano at 270C, I can't rest yet!
Dude. That’s fast. So we’re thinking of designing our own derailleur and then getting it made in carbon fibre.
Great idea, can't wait to see it! Might be a good forged CF project ... it's not that hard to do at home with the right materials and a 3D printed mold!
ender 3 with e3d v6 and volcano, on v-wheels and dual 5015 under 7min 🤣

True enough, but I'm not done yet ... I've tested 100k travels on this machine so I've got overhead yet to explore :O But there will always be someone faster, and this machine will never be the fastest
First
Second
Just get a Bambu Labs X1c and wait a couple more minutes for a much better print.
This is just uglyboating for funsies, friend 😘 I can get dang near perfect prints out of this machine just by slowing it down a little, and my standards for "dang near perfect" are very, very anal. I built it for quality (high resolution, high rigidity, low moving mass), it just happened that most of my upgrades for quality also made it faster -- and nobody really cares how nice you can print, just how fast, lol.
@@jamespray Very cool...
