yes. i knew that.... i want to do something a little quirky. plus - i dont have the funds to build a 100ipm gantry cutter myself. i have very little $$. i cant even spend $300 at any one time to buy 80/20 parts. i end up using plain-ol 1.25x1.25 alum square tubing.. and acrylic... and lots of hardwarestore alum and steel extrusion.. i think the robot arm is an obvious winner at this point - cheap, fun, etc... a gantry table that does 100ipm is not offered in a $30 planset for good reason..

the robot plans would cost no more than $15-$20 - postpaid..... maybe $25 for europe if it costs that much more to ship there...

if .pdfs were not SOO easy to share. i would do a digital distro also. maybe if i made each set of instructions have a password that was the purchasers creditcard # they would be less inclined to "share" the plans...

if i had help on this beast, i would put it out free.but noone will ever help me. my friends think im crazy, and on the internet people are very selfish.. they just want to get what they want out of most forums.. my favorite is people who think their very first attempt to build a very complex mechtronic device like a cnc machine is gonna replace their dayjob..


you will never build a 100ipm CNC device with hardware store parts for linear actuation - at THE LEAST, you will need ball screw, toothed belt, rack and pinion, or other locomotion.. this is not cheap.. even toothed belts seem to be very pricey.. even 10tpi leadscrew would require 1000rpm for 100ipm. i would not expect any stepper system to be accurate at those speeds. maybe at 600-800rpm, with propper acceleration.

i cant believe a 1inch toothed belt pully is $50. but, hey. it is.
