Hello all.
New Member hoping to get into the world of DIY Self Build CNC machines, primarily a router initially.
I have no practical experience of CNC Machines but did some Coding simulation in Auto Desk Inventor during my Mechanical Engineering HNC course several years ago.
I have a new project coming up next year where I will be converting a VW Van to a Camper. The furniture units can be made or bought as a flat pack and installed but you get a generic layout unless you commission a bespoke build which can cost 1000's.
So, being the inquisitive type I am, I am looking to make my own cabinets from 15 mm Lightweight Furniture Plywood myself on a Gantry type CNC Router.
The biggest piece of board I will have to work with is 1300 mm by 800 mm.
So I have ordered the following from China to get me going and to aide my design. I have a spare 32 bit PC to use with the CNC Software and will use Autodesk Inventor on my 64 bit PC.
2pcs SBR16 - 350mm linear rail
2pcs SBR16 - 1000mm linear rail
2pcs SBR16 - 1500mm linear rail
12pcs SBR16UU block
1pc* SFU1605 - 350mm ballscrew with ball nut* *(BK12/BF12 end machined)
1pc* SFU1605 - 1000mm ballscrew with ball nut*(BK12/BF12 end machined)
2pcs SFU1605- 1500mm ballscrew with ball nut* (BK12/BF12 end machined)
4pcs BK/BF12 Support
4pcs 6.35*10mm coupling
4pcs Nut housing
I am planning on having 2 X-Axis Ball Screws to avoid rake, I just don't know at this stage how the 2 screws will be driven. Belt driven form 1 NEMA 23 motor or each screw with its own motor (I have ordered 4 motors/couplers/drivers).
I'm not sure yet how the X-Axis rails will be mounted but I want to investigate the possibility of the rail supports (maybe 10) being initially setup using a multipoint water leveling system where it will allow many support blocks, all of exactly the same size to be set and levelled on a set of connected water towers (110 mm Plastic Pipe) before they are fixed in place by some means.
I have worked with casting polyester resins in the past, so I want to explore the possibility of casting the Gantry in one piece. So, the 2 X-Axis side supports and one pierce with eh Y and Z -Axis main back plate.
So, I would like the thoughts of the community on my plans and welcome any feedback even if negative.
