about to build my first CNC machine

[Clive S]

thanks Clive , yeah, not buying electronics just yet, i do want to order screws, rails and blocks as soon as i can, would like them here before i start build slightly, unsure on pulley requirement re screw length. i am thinking would be better "FOR ME" with my nursery status in cnc , to actually build , then using a spring scale AND torque wrench(if i knew what size wrench) i could see what is required to turn ballscrews and move gantry

Well I would still get the designed done first as it could save you a lot of dosh if you buy the wrong bits.

nema 23 motors are the norm for this size of machine (low inductance) and 1610 screws x and y 1605 for z

1610 screws x and y 1605 for z

little experience here though i was thinking i might need 2510 ballscrews for X , though now i think 2010 suitable , i would have liked the resolution 2005 could give but thinking that might require to high RPM, i suppose some further plans need drawing up then i will take your sound advice for build log with questions in one place. gotta think more which direction i'm heading, just that i had almost been set to start ordering ballscrews & rail for option 1, though the more thinking "do i want to do this seriously?" option 2 seems more sensible . i have not looked at much depth into smaller precision aluminium mill type machine . the thoughts of coolant all over the place , or bits breaking an dinging the window through. yep back to the library for me

if any moderator could be so kind to delete this profile , as i can't seem to see an option to delete . THANKS
