Large aluminium profile build

Boyan I don't know why you always insist on rotating ball nuts for this size of machine my router is 1600 x 1000

I can easily get 10m/min with 2 x nema 23s the screws don't need to be as long as the table.

I agree with Clive on this point. Rotating nuts only start making sense if the axis travel you want is over about 1.6m and start looking like the best option at around 2m. Otherwise they're just unnecessary complexity and will result in worse performance due to the higher inertia of the assembly.

I missed that cause he said " 3000X1500 table" so i missed that the router is quite smaller. Sorry for that. Then all else what i said stays same except ballscrew size

I never have insisted on rotating nuts for a small table less than 1.8m???

While we don't agree on exactly whats needed for good machine I'm not so sure you need to appologise Boyan because of this statement.

I would like to be able to work with full sheet material so I’m thinking of a 1300x1500x150 format (total size not workable area)

Full sheet to me means 8 x 4(2440 x 1220) so think the OP has got his sizing mixed up.?
