That might work...

I'm guessing you need 1000rpm becasue you have 1 or 2mm pitch leadscrew? Remember if you gear it up for faster revs you will lose torque which will affect the depth of cut you can reliably/cleanly achieve. So you might go faster, but need 2 or more passes... so no faster overall....

On a 1m square machine, how are you stopping the Y-gantry crabbing? are you having 2 leadscrews, one each side?
