wOOt!
I had some serious computer issues literally minutes after I turned on my coolant pump for the first time. Still not sure if that has anything to do with the root cause or not, but I FINALLY have the problem fixed. Turns out the RAM in my computer was TOAST. So, after nuking my Windows install thinking it was the problem, ripping the computer back out of the Mikini, lugging everything inside to troubleshoot, etc., I am BACK ON LINE with the computer remounted in the Mikini (this time with Nylon screws to keep them electrically separated), a new stick of Corsair XMS2 2GB memory, and everything appears good to do.
So, I now also have some video of cutting metal!!! My first aluminum piece.
First pass is 0.0417" DOC, second pass is 0.0833". Tool is a 1/4" HSS cheap import bit. Spindle is 5000 rpm. Width of cut is 0.125".
Pix of the finish:
Video going up on Vimeo, will post it as a reply when it is viewable...
VERY happy right now.
I think I also finally understand how to use G54 with homing, so I am getting pretty dangerous now! I have a couple chunks of aluminum I will do some playing with using some Z rough and Z finish 3D contouring, hopefully this week. Very excited to get something "real" off the machine!
