Hi newbie looking for advice

Hi all,

Hi and welcome to the forum!!

I'm looking to build a CNC router

Well there's plenty of info on here for inspiring your build so you've come to a good place!!

The bed will be made from 40mmx40mm T section steel with slotted idlers running on the outer edges (for now ) for the gantry, and similar for the y axis gantry

Not ideal as will need machining to get a decent flatness but depending on what you want to cut (what do you want to cut?) will probably be ok.

bed size is 1200mm x 600mm (so i can get a full 1000mm x 500mm cutting are)

Doubt you'll get 100x500 out of the dimensions you state, it's amazing how much room the gantry and Z axis take up. My machine is 1300x850 and I get 970mm x 500mm (just!) but that's because of the design I went for!

I've seen on the net a motor kit, NEMA 23 motors (1.8 step 178.5 oz inch)
DM542A driver
350w 36v 9.7A switched PSU

now will this set up be ok the motors will be driving a belt two to one reduction gear then timing belt for the x and y axis
and a screw for the z axis (200mm)

thanks mark

Generally motor kits are not matched very well, the motors tend to be high inductance and the PSU underpowered resulting in a slow machine. You're far better off buying separate items which the lads on here can recommend.....but only really worth doing that when you have a design up (which we'll happily critique) and say what you realistically want to cut.
