How are you going to control the machine? Are you going to stick with transferring the gcode on an SDcard or direct connection with a computer or laptop? That isn’t necessarily an added cost, but something to consider. Figuring out a CAM program can cost or not depending on what you choose. I paid the $50 for Estlcam and it is doing great so far.
Also the base/table, spoil board and those goodies.
Dust collection is important, however you figure it out. Without a vacuum close by, everything within a four foot radius is going to be covered with a fine dust and especially if you are hogging out a lot of material making guitar bodies, you’ll need something for that.
Of course, just getting bits or end mills is a good start and you can do a lot right off the bat. Looking forward to seeing your build and your projects.
i think i am going to use a laptop and direct connect it to the machine that just sounds easier to me . as for dust collection i am using a shop vac for that . I know i cant use it to program but i do have CadKey software at home , i was wondering if there was an easy way to draw in it, then dump it into a CAM program . How long have you been using your machine ,are you happy with it?
