    The Fantastic Plastic CNC Mill

    The 23 cents would be my price I could probably get at least 35.00 for a piece that size on line.I could sell it to makers or small shops any size they want.Sounds quite profitable to me.

    Best of luck on the build.The machine cutting area is about 8 3/4" on the x and y and 2 1/2" clearance for the z so adjust your measurements accordingly if you need more,not too much larger though as there will be too much flex resulting in broken bits.You might want to consider a spindle capable of low RPM when cutting plastics as it tends to melt through rather than cut.

    I'm not sure although I've had no problem removing the pieces without the use of any release agents.Perhaps the metal shrinks a bit when it cools.

    I checked out online for a ballpark price on UHMW a 12"x12" x1.5" thick piece goes for 98 bucks U.S.probably no more than 5 lbs.Definitely considering reselling on my website.My friend is a big time player with at last count 5 five by ten cnc machines and goes through tons of the stuff.

    That is why I didn"t have motors in the title picture.It is meant to be a mechanical build.My electronic skills are limited to say the least.I used a 3 axis Nema 23 DIY electronics kit from "cncrouterparts.com it's practically plug and play.The post processor software is Mach 3 well worth the money,lots of tutorials for the setup.I use Cambam to generate G-code and found it user friendly as well.There are lots of good Instructables on Arduino hookups if your comfortable with electronics.I would avoid using Nema 17 motors as they just don't have the holding torque under the load of a router mill which results in missed steps and a lot of frustration,believe me I've gone that route.There great for 3d printers and laser engravers but you need at least 125 oz/in for a mill.Mine ar...see more »That is why I didn"t have motors in the title picture.It is meant to be a mechanical build.My electronic skills are limited to say the least.I used a 3 axis Nema 23 DIY electronics kit from "cncrouterparts.com it's practically plug and play.The post processor software is Mach 3 well worth the money,lots of tutorials for the setup.I use Cambam to generate G-code and found it user friendly as well.There are lots of good Instructables on Arduino hookups if your comfortable with electronics.I would avoid using Nema 17 motors as they just don't have the holding torque under the load of a router mill which results in missed steps and a lot of frustration,believe me I've gone that route.There great for 3d printers and laser engravers but you need at least 125 oz/in for a mill.Mine are 380 oz/in and have never missed a step
