Hello mates, from across the pond.
My first CNC I built was around 1997, built almost entirely from LEGOs. I added my own steppers and homebuild electronics to control 2 axis using MS Qbasic. How far we've come.
My recent CNC build is a giant 40x20x10 (inches, sorry that's how we do over here) horizontal machine for general purpose but I mostly design and cut molds for 1/10 RC car body vacuum forming.
I use LinuxCNC with the HobbyCNC 4 axis controller.
I almost always end up doing "5 setups" to get at the top and 4 sides of each mold. There are almost always undercuts and fine engravings on the sides. I can manually tip and rotate the spindle on my machine.
I'm thinking of trying to build a sort of indexed lathe/2axis hybrid machine to get at all the different angles and undercuts with only 3 axis movement.
I'll try to find the right forum to post my ideas and questions in.
Thanks
