Well I did some drilling today, got the y rail holes drilled and the linear bearings set now i just got to cut the gantry bottom any suggestions on how to measure the length or should i just make it longer then attach it and cut it...

[daveCNCmachine]

well I got building a little at a time, I got the y and x axis done, I had started building after the jgro design, but modified it a little, and had the side gantry's done, but split the mdf rushing to get the bottom plate on, so i made two new pieces and routed in the L angle so far i only used 2- 2 x 4 mdf 3/4" sheets, 1-4' peice of L angle and some bolts all together about 120 dollars, I used dado's for some of my joints, working on uploading some pics...

any suggestions on stepper motors and controllers kits, i will be using my dremel or roto zip for the router... does anyone have a list of links where you bought kits from... ??

Well I got most of the mechinical stuff done, now just got to figure out the motor size and where to buy the driver etc need a few bearings for the lead screws etc couplers etc...but its getting there found out my working space is like 15 x 18 i will post some pics soon...any suggestions on how to figure out the motor size needed?

I would look at these, For that size I think they would be right on.

Nice build there, I have started mine and will be getting the X axis done tomorrow or the next day but that looks a nice machine and I wish I had gone the angle and skate bearing approach rather than the oilite rout very unforgiving. What will you use your machine for ?

[daveCNCmachine]

well I got my package today with my lead screws and some bolts and bearins for it, here are some pics...
