HI Guys,
any of you built their CNC machines for kite and foil or board making?
(Hot wire foam cutters, lasercutters, plotters or milling machines?)
Thought I share my design and progess maybe there´s more feel free to share your´s
Currently designing and building a 3x1,6m CNC X,Y plotter for my DIY foil kites. Maybe upgrading it to vacuum table and lasercutter later but first I want to get it work plotting.
Status right now: I use linear rails from ebay ( HGR20 for Y-Axis and SBR16 for X Axis) built a big table from ikea linnmon plates and mounted the big Y Axis traverse and X Axis bearings. I think I´ll redo the connection of the traverse to the bearings with a more sophisticated 3d printed connector though.
Lessons learned so far:
The HGR 20 bearings run a bit smoother and have less play and can transmit the moments better without blocking if not 100%alligned, so next time I woud use them for all axes, although it is a lot more expensive.
Cutting the rails is nearly impossible without an angle grinder because they are made out of (really) hardened steel, so I could not even scratch them with a normal metal saw or multimaster tool.
To do next:
Make some 3d printed parts and order all the timing belts and stepper motors and install the rail on the Y axis.
