hello im thinking to make a new cnc router for size 5x10 so my question is im going to use rotary ball nut,do i need 25mm or 32mm ballscrew for 10 feet axis and do i need high pitch screw such as 25 or 32 since im thinking rotary ball nut doesnt have critical speed maybe i can use 10mm pitch and just spin it 3000-5000 rpm with 1:1 ratio belt,
and im going to pair it with 750-1kw 3000-5000 rpm servo for it i already.

i already got quote for my supplier

rotary ballscrew 3232 10 feet=350 usd
rotary ballscrew 2525 10 feet=300 usd

my target rapid is around 1500-2000ipm

thanks
