Comment on Why do we still use stepper motors?
beeb@lemm.ee 1 year ago
Have you seen how fast printers with stepper motors can get? They print benchies in less than 3 minutes. The bottleneck is not the motion system, it’s either the hot-end or the part cooling. Also stepper are super accurate and very flexible. Drivers are advanced and can tune for torque, speed, sound etc. Collision detection is also a thing.

Not disputing, I want that 3 minute benchy. Where does one find this magic?

The print as absolute shit though. Literal garbage.

Looks pretty good for the speed to me! This is an experiment. Someone will be able to build on that and make it better.

Speed Benchys mostly are garbage quality.

This is as fast as I’ve seen for PLA while still retaining good quality. And he probably could go faster with more powerful motors or more of them.

This is mostly a cooling issue. Not being able to solidify the plastic fast enough after it’s been deposited.

Tune up a coreXY like a Bambu or Voron, use all the latest features in marlin (like MPD thermal and linear advance.)(I assume other firmwares have similar.

Yeah does anyone have a link to a 3 min bench print?

It’s custom made printers and it makes shitty prints.
