Hi
My dad owns his own joinery workshop but wants to be more competitive with price and a CNC in the workshop would do this.
As his background is in woodworking sidewinder cnc on youtube caught our attention due build materials being made from ply.

Basically we have his plans and wish to upscale them to cut a 8x4 boards.https://youtu.be/-jujswCDgzQ is the link to his series of videos. Please educate me on the issues that will/might come up with the up scaling of the plan? Is ballscrew the best option when travelling 8x4 board?

Thank you for any replies
