I'm new to this world but experient with 3D Printers. I seek advice for a good and robust machine that able to carve aluminium, big step not required, it can go slow and small depth step.
At first i was looking at the new LEAD CNC from openbuilds, but it have many drawbacks at my eyes:

  1. It use 8mm leadscrew for 1000x1000mm which is a weak point
  2. Don't like vwheels, i even convert my 3d printer to linear rails, not to mention that heavy spindles on Z will not hold very well
  3. Frame not very rigid, have some deflection working over big areas


Reinforce LEAD would cost it price again so, with that in mind i start to find other alternatives on near price point, that i came with 8060 chinese CNC's (https://www.aliexpress.com/store/pro...817911749.html). They look better to me in terms of rigidity and choise of hardware:

  1. Proper leadscrew diameter
  2. Smooth rods instead of wheels with good diameter
  3. Better Z
  4. Stronger frame
  5. Electronics seens well choosen, they even use high power drivers for each motor, instead of LEAD that sell underpowered controler board with only 1.7A drivers with 2.7A motors... (Blackbox fix that with 4A max.)


Now i want a good spindle and i come with this one: https://www.aliexpress.com/store/pro...881434813.html
2.2KW and ER20 the only drawback is the weight, assuming that seller put the correct value info: Net Weight: 6.1kg.
But i'm not sure that i really need a 2.2KW spindle... Maybe 1.5kw will carve aluminium?

My ideia so far is:

  1. Get 8060 machine
  2. Discard controller box and spindle, i already contact seller and that's about 500€ deduction in price.
  3. Buy the spindle i link before with VDF and water stuff.
  4. Buy the new Blackbox from openbuilds to use with grbl and their software.
  5. Buy a power supply


And now my question are:
(Renember i don't know about CNC world, yet i hope)

  1. Is that a good setup to go?
  2. Will 8060 frame survive that spindle?
  3. What about the deflection on axis?
  4. Can i get a better config?
  5. What are the recommendations?
  6. Have other better machine advices under +/-2500€ price range, 3000€ max?


Also i like to know if i get any advantage going with this: https://www.aliexpress.com/item/Jade...950734919.html
