Why are 3D printers still stuck on stepper motors? Why haven’t we transitioned to servo motors with encoder feedback for positioning?
Is it just too cost prohibitive for the consumer-level? We would be able to print a lot faster and more accurately if we had position feedback on the axes. Instead we just rely blindly on the stepper not skipping any steps when we tell it to move, hoping for the best.
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 and skipped step 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.
Speed Benchys mostly are garbage quality.
This is mostly a cooling issue. Not being able to solidify the plastic fast enough after it’s been deposited.
No shit lol

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.
