Hello Redzilla,
When you recapped the supply, did you change all of the electrolytic caps or just the output side caps?
I ask because I only recapped the output side and am still getting ~ 300mv...
Hello,
I think I have figured out my ATC tool jam problem on the 720.
If the air pressure drops below 95 psi the ATC sometimes fails to load the tool holder, because the drawbar does not fully...
Update,
I may have found out how the ATC fingers were broken. I was testing the ATC, having it load a 5/8 end mill and then put it back and then load a 3" facing cutter. I had ran this programs...
Update,
I shortened the cable, machine works the same. :-)
Thanks,

Hello All,
I am now trying to cut a simple circle to measure for accuracy.
Keep in mind this is the stripped down bridgeport TNC 351/355 without graphics which means no block form setup in...
Update,
I had the wrong pull studs, with the correct ones the tool holders lock up just like they should.

The correct spindle motor is: FM7-A055-S1C1-E01 Which is a match to the Fagor Spindle Driver...
Update,
Yes, the slow spindle speed was a operator error, when I put in 4k for a speed it worked just fine. I did notice if I turn up the speed greater than 4k it gets a spindle error.
So the...
Update,
I replaced power supply U1 and now the 720 comes up and completes axis reference. :-)
FYI, I do not have the air hooked up yet, and the machine has had the spindle driver and power...
