Show"N"Tell ( Your Machines) / New Build 6 axis CNC first timer
« on: March 31, 2009, 03:18:34 PM »
Hey folks, go big or go home right?  Anyway, I'm building a 6 axis cnc and would like advice and pointers as I order parts and what not.  I figured I'll order all the electronics first, make sure they work, and build the machine around them.

For the final machine, it's going to be a moving gantry system with an A/B head from doughty drive.  Initially the machine will be 5 axis.  The 6th axis will be added later to the table to revolve objects.  The cutting surface, I plan on being about 4' x 4' x 3'.  I will be primarily cutting wood, soft and hard.  Sometimes I'll be cutting metal as well.

Here's what I've ordered so far...

1.  USB Smooth Stepper
2.  7 Gecko G203V drives
3.  4 Nema 34 1250 oz motors
4.  Mach 3 (of course)

What I'd like advice on from here, would be:

1.  Power Supply (I need it to power each drive, which in turn will power the motors, remember there are 7.  The gantry will have two drives/motors to move it.)
2.  extra switches like limit switches, emergency cut-off switch (how many, and where?)
3.  wire (what's the accepted standard, how many colors etc)
4.  kit box to store everything neatly (Are there large locking ones?  Do we all make them by hand?)

Later on I'll ask questions about the frame.  For now, it's only electronics.
