The A8 is quite decent after getting rid of all the original parts and rebuilding it from scratch. I see.
Good job! 👍 You learned a lot from the original design and from your improvements. That's what the hobby of 3d printing is all about, if you ask me. I went through similar efforts with my Ender 2.
Nah, 3D printing as a hobby actually involves printing things. What you are describing is 3D Printers being the hobby. That is fine too, but too many people can't seem to make the distinction that they never actually make anything.
Definitely learned a lot. With these upgrades I hope it will last me enough so when I have more disposable income I can build a Voron or something of that caliber.
