Hi all as quite a few others have said, I have been lurking around for a few weeks and decided to make my own machine.
I would like to say thanks for all the great info everyone has put on this site.
I was given 3 25' and 15'' linear motion rail. They are basically 8020 type extrusions with 25 series linear mounted inside a cog belt positions a aluminum piece mounted to the rail. The positional spec was .005 so I figure I am in fat city.
I am cutting up the extrusion to make the rest of my machine which will have an 4'x8' table. The X axis will be two of the rails cut down to 10' and some change. The Y axis has 53" of travel the Z axis 12". I am using Acme screws for both.
I plan on the xylotex 4 axis 425oz motors, and a DL05 plc for my e-stop and some of the limits/homes. I will also be purchasing Mach 3 for the control.
I still have a few things to figure out, I hope to get started on it this weekend, if the honeydo's don't get in the way again.
Thanks
Glenn
