CNC Router V1.0 (For Cutting Multiple Materials)

[biketrialsdave]

Thanks for the feedback. Twin Y axis (I assume you mean Y?) ballscrews was on my list, I will probably add the mounting holes in so I can add them in the future. All plate will be 20mm thick I think.

Been doing some more work...



At the moment I only have 2x Hiwin carriages on the X axis. Would there be much benefit/need to double up on these? I.e. two carriages per rail? If so then I will need to increase the X axis length to get a decent travel. I am leading towards this anyway...

Definately. The rigidity will be greatly reduced if you don't use two, since with only one on each rail the axis can more easily pivot (or 'rack') about the center point, i.e. the ballnut, which on the gantry will cause the cutter to deflect substantially.

Will add some more carriages in tomorrow :) thanks!
