    Ox, it's probably a case of burned out IGBTs in the spindle drive, so maybe just get a set of IGBT modules and replace them?

    A volt meter can tell you which of the 3 phases died, assuming it lost...

    The thing I didn't like about that type of work is "here's some random widget, make 10 of them" and you have no real idea how the thing is used or what is legitimately a tight tolerance...

    I'm gonna take a stab and say you are doing this on a Tormach 440 and don't have flood coolant. I used to do a lot of Aluminum with Kool-mist and a Shizuoka AN-S.

    I'm assuming he took a PS/2 keyboard library and dropped it in, then replicated the matrix pattern Fadal used for the keypad.

    The Parallax Propeller is suitable for this as well, there is a ready...

    Since all Fadals accept "keyboard" input from the serial port, I don't see why you couldn't make a "terminal" that takes a PS/2 keyboard input and echos the Fadal character codes to the serial port....

    I bought a digital mitutoyo indicator with the intent of measuring camshafts. The idea was to motorize a rotary table and have a computer digitize the camshaft. Motor spins rotary table and then it...

    Bobw knows more specifics, but I would presume they are talking about a 32MP control. The one with a Windows computer running along side the Fadal.

    These were based on the -6 CPU card I think. ...

    The card is either probably aged out or needs some components reseated.

    The -4 card is a PLCC 80286 processor last I checked. If you have a humid or corrosive environment, the pin connections can...

    I think he mean that 11.86 is the low voltage cut out, so as long as you are above 11.86v it's good. That doesn't mean the power is clean though, a noisy DC bus can cause all sorts of havoc. This...

    Is your backup battery dead?

    It does no good to initialize the RAM then boot it back up with corrupted data.

    If the battery backup is dead, the RAM will come up all garbled.

    If it goes into...

    The fact is you have a tub for catching chips and a tray and a bucket, all of which takes up the space of a 55gal drum, but holds 6 gal worth of chips and 5 gal of coolant.

    Since all 3 of your posts are about Cow Carts, I'm gonna assume you are shilling for digging up a 10yo thread. Not to mention that the weird cart you're hocking has nothing to do with chip control. ...

    64K should be enough for anyone!

    My machine came with 32K and I upgraded it to 160K (the max for this machine).

    I've found that 160K will hold a lot of G-code if you do a half sane effort at...

    Flip the table onto a bench, then use the saddle to scrap in the table. I'd guess the saddle is less weight than the table.

    I used an engine crane to R&R the table on my Fadal, but it has hard...

    Buck-Boost transformer for CNC

    The background: These are from "Coherent" (brand) lasers and are 10Kva. The voltage range is very...

    They have 2 casting holes for forks in the base, you just put some strong steel through those and pick the machine up with long forks.
