The bottleneck is the extrusion and the cooling of the extrusion. Not the transport system.
Comment on Why do we still use stepper motors?
DreadPotato@sopuli.xyz 11 months agoI mean, 3-axis robots move at 2000m/s with 0.01mm accuracy with payloads weighing considerably more than 3D printer toolheads, using servos.

2 km/s? That’s almost Mach 6.

Yea that’s why you have to wear hearing protection in factories.

Yeah that was a typo, obviously that was supposed to say mm/s

What’s the cost difference between the two?
7heo@lemmy.ml 11 months ago
Yes. 2000m/s and 0.01mm accuracy unfortunately means nothing about acceleration and control.
Knowing your system, you can achieve that with motors that can only accelerate at 0.01m/s² and that cannot break.
The 2000m/s and 0.01mm accuracy say nothing about the capability of the hardware in the case of multiple sudden direction changes.
That’s like saying “this car has a top speed of 200mph, and can reach any GPS coordinates precisely, so of course it can zigzag from side to side using 160° turns in a one way street at high speeds.”
