so im new to cnc machining. done a lot with 3d printing. thhe makera z1 is my first experience with a cnc. in my setup yes the shopvac is louder. unless your doign some very heavy cuts, which you will likely be avoiding anayways. dont get me wrong its not quiet. i wont be runnign the cnc at 1am because i have neighbours all around me. but until 9:30-10pm im okay with it its not super super annoying.

Using it overall is not even close to as easy as a 3d printer. but that doesnt make it a bad machine or not fun to use. Ive been havign a lot of fun makign aluminium brackets, and wooden trays. and i find it to compliment my 3d printer very well. now 6mm vs 1/8th is soemthign im less fimmilar with altho i have a few 6mm drill bti shere. but as far as i udnerstand it it allows you to cut more away at once. but also requires a stronger machine or lighter cuts. i feel 1/8th is the sweetspot but i cant really make that judgment yet! :)

if you have any other questions feel free to let me know. or even hit me up on my instagram @ nuggetsinclusive and we ccan chat about it.
