But that just highlights the statement/question in my OP, it's just cost prohibitive to use servos as a hobbyist. You will as a hobbyist get a better system with (proper) servos, but not for a reasonable price point.
Do you want to have a conversation, or do you want people to agree with you?
Your post is phrased like a question, but your comments feel like the opposite.
If you are buying industrial grade 1000+ dollar servos you are no longer "hobbyist" in the price range that hobby level 3D printers exist steppers are more precise than servos.
Yes that's exactly what I'm saying...it's the cost that's in the way of the switch, not that steppers are the best solution. They're only the best solution within the price constraints we have as hobbyists.
But how do you define "best?" Servos may be functionally better, but if you can't sell your product to consumers because it's so expensive, is it really the best product out there and who exactly is it the best for?
It's like saying Kobe beef makes the best burgers, but if you're trying to feed 10,000 people then wouldn't your typical 80/20 ground beef from Walmart be the best option? I don't think hungry patrons would appreciate paying $100 for a kobe burger over $1 for your standard burger. They just want to eat.
I don't know why you're getting down voted. You're correct, steppers are used due to cost.
You will not get a better system when using servos no matter the price point at the moment. People have tried and failed just because the software support isn't there yet for 3d printing.
The biggest issue I'm aware of is matching the timing between the extruder stepper and the servos that do the XY motion.
Which isn't apparent at lower speeds but at higher speeds you can notice they're no longer in sync which leads to all sorts of issues and artifacts.
I'm currently waiting on some 3 phase steppers and drivers to test to hopefully get something with less speed deviation than a normal 2 phase stepper and more reverse torque but don't cost too much and are still easily driven by connecting a driver to your boards step/dir output.
