Gantry is introduced to the frame for the first time.  Hopefully my CAD skills and measurements are close...

A little while later the gantry is carefully lifted via a floor jack a foot or so of the floor.  Step one..

CNC metal mill drilling pilot holes for the brackets that hold the frame in place.

Brackets welded to cross members and opened up to .75" to receive the bolts that will hold the structure together.

raw steel arrives from the mill..
 Williams Steel In Greensboro NC did and outstanding job oc precision cutting the 2X5 X.25 (inch) steel tubing to size.

I got right to work welding the pieces together. Each side of the frame is a hefty 280 lbs.

A day later, both sides are ready for assembly..

Been working on the design of my latest machine. I've got a half dozen cnc machines under my belt now and with the help of others here on the forum and 2 years designing the build has started on my most ambitious project to date, a 5 axis mill.

I plan to use the machine to help in the fabrication of the sculpture that I create. Specifically

 3D carving of the female form.

Here's a couple of examples of my sculptures and the general layout of the machine.

Hey Hood, still working out the details of the final shape of the machine frame.

If you like you could post the line driver PDF here?

OK, all, Hood in Scotland was invaluable in got me pointed in the right direction.  I've got G&L drives working and motors tuned, interfaced with Mach!

Good stuff, great camaraderie, This site rocks!

Hope I can return the favor and help the next person move forward!

Best, Tristar500

OK, no more errors there after making that change.  It's telling me to set the hall to 300 degrees?

got into the DSAPro communtation Diagnostics.

I run a test at 10%,  The motor moves but somewhat erraticly and the software recomends wiring changes "V conection move to W,  W connection move to V"

I have no idea what a V or a W connection is?

I had to change the file extension to .txt so the forum would allow me to upload it.

Here it is.  Hope it makes more sense to you then me.

I"ll try that..  One other question. The motor connections on the drive are labled R,S,T, . Is it important how these connect to the motor?
