Hah, I guess "thread count" is the term used for linens, isn't it?
Maybe you can answer another question. As a confused newbie, I get a little bit mixed up reading some of the DIY CNC pages out there. On this forum, I've seen it said a few times that building a machine will cost somewhere between $500 and $1000. But Cranky's plans boast less than $200 for parts.
Is this because it's a starter model? Or is it a difference of opinion regarding what is necessary (maybe using rescued printer steppers instead of the higher torque ones)? I mean, I have no intention of cutting aluminum. I'd be surprised if I routed anything harder than sugar maple.
