I have been reading tons on how to make these things but im sure all of you went through this, it can be mind blowing on the information. Where im trying to get at here and is my main qeustion, where do you guys come up with your builds? I have found some sites that want you to pay for a build plan but i rather not do that because i want to make the machine exactly what i want. Any sites that just give you free plans so i can come up and start adding to my own design? Taking what i like and dont like? Im not finding any plans out there besides the one that want you to pay.

Solsylva CNC Plans~ Home Page is what im looking at, any good things about this place? Personal experience?
Sorry so many questions any information would help, thank you
