Hey
I want to build CNC router mainly for wood processing (MDF + Plywood up to 30mm thick) I need the machine to cut/drill the pannels with less then 0.5 mm (or 20 mil) resolution.
and sometimes i intend to cut/drill aluminium profiles on the machine (it doesnt has to to that fast and i can go at minimal feeds)
also the CNC will be 1500*1500mm (and i need 1300*1300 effective working area)
also the budget is about 1000euro for everything

Im alittle affraid the machine will be not sturdy enough and will resonate and get bad surface finish or will not be accurate enough

I have already ordered :
steel 100*50mm tube profile (with 3.2mm wall thikness) - for the frame and gantery
2.2KW chinees spindle
Nema23 steppers 2.2N/m

now i want to buy all the moving parts:
* linear rails: i was thinking about HGR20 (4*1500mm and 2*300mm)
* ball screw screw 2005 due to the lengh (3*1500 and 1*300mm) - will 20mm thick ball screw be ok- or the ball screw will bend?

as a kit from aliexpress - to save some money
