Why do 3D printer manufacturers not get the details right? e.g. rotation indicator on bed levelling wheels (lemmy.ml)

Building a 3D printer is easy. Getting the details right to build a great 3D printer is hard, as this is where most companies fail. Why?

For example, on this printer, the bed is a three-point mount (two wheels for adjustment at the front of the printbed) and the printer's bed levelling dialogue doesn't show the height difference that needs to be adjusted (which most 3D printers do). It does show how much it needs to be turned, and the bed levelling wheels have 1/8th turn indicators, making it easy to get it perfect.

In short, instead of an arbitrary number like 0.3mm that has no meaning to the user, they tell the user to turn this knob 1/4 of a turn. An instruction the user can follow.

** Why is this so outstanding? It doesn't cost much, but it improves the user experience. Are companies blind to these improvements because the engineers are experienced, or is there a lack of testing during development?**

By the way, years ago I did such a fix/modification myself on a Tronxy XY2 pro by adding indicators on the wheel for 0.2mm height difference so I could convert the number to rotation: https://www.printables.com/model/301670-replacement-bed-leveling-wheel

a lot of these printer manufacturers consider it an extra cost since these are subtle things when compared to the manufacturing and mechanical design of the printer.

If there would be a $150 Ender 3 and a $200 one with identical hardware but perfect usability for beginners. I expect more people would buy the expensive machine compared to releasing a noname Ender 3 clone which tries to beat this hypothetical $150 price point.

An example would be the AnkerMake M5 and BambuLab lineup.

Yes but that wouldn’t make sense for Ender anyways. They’d still have to hire an Industrial Designer and other related professionals to take the existing design and improve the user experience. As another user commented, printers aren’t targeted for mass market so the considerations for a mass market (well defined affordances, ease of use) won’t be considered.
