Показать описание
The Real Sam Prentice and Lost In Tech came to nerd out at E3D HQ to talk all about the latest addition to our Extruder family - Roto. We delve into our design choices, the impact of extrusion force vs volumetric flow rate, and how E3D test volumetric flow rates and validate print performance.

P.S have you ever seen a Rat Rig V-Minion move at 40,000 mm/s²? 😉

00:00 - 01:42 - What is Roto and who is it for?
01:43 - 01:52 - Key design goals
01:53 - 03:35 - How we designed for the 'majority' of users
03:36 - 06:13 - Lost In Tech: Extrusion force vs volumetric flow rate graphs
06:14 - 06:34 - Stalling vs shearing filament
06:35 - 07:05 - Why is Extruder mass bad?
07:06 - 07:53 - How heavy is Roto?
07:54 - 09:10 - Rat Rig V-Minion with a Roto moves FAST
09:11 - 09:45 - Why we chose a custom motor for Roto
09:46 -10:50 - How does E3D test volumetric flow rates?
10:51 - 14:01 - Roto vs Hemera flow rate comparison
14:02 - 15:33 - How does E3D validate print performance?
15:34 - 16:53 - Roto's usability features

Great video, lots of detail and no flashy sales gimmicks. really excited for the Klipper toolboard. that will be a pay day add to cart.

Great video! How can I run the test print on my extruder to see where my current one is to compare the difference with yours?
