The motor sticking off the right end which is for the z axis says 66lb in, not sure on the x axis or tool turret but I am guessing the z is the largest . The spindle motor is 30hp I believe.
Here are a few more pics

its a seperate pic the fellow sent me, The machine was up against the wall and the door would only come open about 8" so he lowered his camera down in the cab and took half a dozen pics.

I wonder if the drives/amps are not present if the Rutex drives for brushless 3 phase motors will work  or if I might do better to buy commercial drives? I dont have a ton of money to throw at the project but I have set a budget of about $5k  initialy

The motors are 3 phase brushless GE , I was told all the wiring in the 4 foot wide 4 foot tall electrical cabinet on the back is intact and nothing has been removed from it, looking at the pics of the inside of the electrical cabinet it doesnt appear anything has been removed but I dont see anything I instantly recognize as drives/amplifiers as compared to my milltronics machining center . Its due to arrive friday evening around 7pm . It originaly had a fanuc 10 controller. Very excited to get it here

adjusting the debounce value let mine settle out , I do all my threading at a lower spindle speed (usualy 2-300) also and havent had any problems and I have threaded both ends of a couple of hundred suppressor tubes recently

its working fine for me, it will only accept feed values for x axis infeed feed rate when the z start point is a negative value which should be the only time its needed

I have a couple of c11 cnc4pc boards and it requires two seperate 5v power supplies and both have to be hooked up for it to work. one can pull 5v from the USB port and is a simple 2 terminal screw strip and the other needs a seperate 5 power and is a longer connector on the other end of the board, They both have to be hooked up for the board to work, and they have to hooked to two seperate power sources  to maintain opto-isolation . The condition you describe will occur if only the long one is hooked up

I am using  p3 566 computers to run mach3, one on each of my lathes  and other than having to upgrade to more memory on one of thm I have not had a single problem. Both have XP loaded and work wonderfully

the cnc4pc board needs both an external 5v power source and 5v from the usb port , if just one of the 5v inputs is powered it will cause the leds to dimly light.
