Help Needed From the CNC Guys

(1/5) > >>

75Plus:
I recently purchased a Grizzly G3617 mill from an estate. The same mill is sold as an HM-52 down under. It had been retrofitted to 3 axis CNC with three Nema 42 stepper motors along with a 3 axis motor control unit. There was also an older computer that had some control software installed. The question I have is what else do I need to get this thing on line. There appears to be a missing link between the computer and the motor controllers.

John Stevenson:
We need photos of the controller box you mention

75Plus:
Here are the pictures John. Appears to just be three discrete controllers, a couple of power supplies and a 25 pin parallel port to tie them all together. The software is by Flashcut CNC and refers to a signal generator to allow Windows to run the program.  That is why I think something is missing.

John Stevenson:
Bit out of my depth on this one as never had any experience with Flashcut but they are still around and have a web site.

Swarfing:
Assuming the machine is using steppers and not servos, then that looks like just three drivers and a BOB. If this is the case then you have everything you need. Go load up linuxcnc or the trial version of Mach3 and give it all ago. I say that simply but you will need to find a few things out like what pins are connected to what and that can be done with a simple volt meter or small bulb.

Going to need a few more detailed pictures of the boards especially of the connections and any labels of those pins. I can't read the labels in the pics so get as close as possible.
