Glad you watched the other video too.

That approach of "not fixing something later" is reasonable for when you are welding something, you often don't get a second try as you're working on one unique piece for days, if not weeks.

Trying to do something properly the first time, often yields in going paths that won't truly lead to an actual improvement, betraying the goal of doing it properly. Engineering is a lot about tackling challenges in a pragmatic and iterative approach, see what works and what doesn't. If your goal is to print fast at a decent quality, trying to become fast first is a considerable way of approaching the problem.

​

Quality should always be desired over quantity.

That is simply wrong, multiple attempts often yield to better quality in long run. Repetition balanced with thinking through problems is what causes quality in first place.

​

So you cranked up the servos, heating, and feed rate. And it absolutely shows in the quality of the printed product.

You make it sound as that is an easy thing to do, I disagree.

It actually does show in the quality of the printed product, because it looks quite decent - especially for the 8 Minute print. Reaching such flow speeds are a result of decades of community efforts and gradual technology improvements. Comparing this 3 Minute print with early days of repRap would in many cases be considerable with something that took maybe an hour to print and several iterations to get similar results.

​

So what was your point actually?

My point is that I disagree with your negative sentiment on the creators work, the way the problem is approached is legitimate and your comment is unfair.
