I built a solsylva 25x25 machine. I used autocad/cambam/mach3.
I'm having some trouble when i'm cutting out these shapes it travels or starts to early. It's not always consistent either.
I thought it might be the flex on my router, since its only wood, but I slowed the cutting speed waaay down and still got the same result.
Anyway look at the pic you'll be able to see what i mean.
