    I am also a huge user of NCplot. Couldn't live without it.

    I tried sketch NC a few years back and was underwhelmed. I'll take another look at it. Thanks for the heads up.

    A three phase load center breaker panel is a GREAT idea. I did this for my son's shop.

    We treated this as a sub panel and ran the two hot legs from the single phase main to this. Each idler...

    Thought you could see it in the pic. I undid the line before and after the hydraulic unloader. put them into the solenoid valve. For under $25, this is a no brainer.

    I'll repeat my suggestion. You got good iron, good servos and likely good encoders. Everything inside the cabinet is 20 year old junk, likely broken. certainly not worth attempting find why it died....

    120 or 150 Hz is the very most you can spin a regular 3 phase 1725 motor. And 7.5 hors is not going to have enough torque at low speeds.

    Two ways to go - bigger motor - or get a back gear. 10Hp...

    If your contactors are not big enough, its going to be easier to just gut that panel and start over. You'll re use nearly all the wire.

    Yep, I'm sure those old BOSS steppers were at least 10A at 48 volt.

    The step driver is going to be maintenance free - when it dies get another.

    I ran an AHHA refit on a Bridgeport BOSS 3 in the 90s. The company went out of business back then. So, they've been done 20 years now. Their design was for DOS only and a parallel port to do IO.

    Say Garwood,

    Are there any tricks to removing burned on carbon? I was hours and hours chipping it all out. I don't know how the compressor even ran but I bet they all look like that inside.
