retrofit Boxford vmc mill 260 Info needed on Yaskawa contactor relay and VFD choices

I don't that's true, I have a small aluminium cnc mill with seperate spindle on off, and a converted Bridgeport mill with cnc retrofit.
the pin setup will be easy for me as I have done that before, but with reverse I'm not going to be doing any climbing so direction is something I can add later if needs. Thanks for the info on the spindle control tho

If your talking about Climb milling then you don't reverse spindle anyway. Reverse is mostly used for things like tapping etc or special use cutters.

So, i have taken the yaskawa apart to determin the wiring for this thing, and it looks like its just needs to be connected to live for the opposing side to actuate. Therefore i am wiring up my spindle controller and will see how it goes! I need to install MACH3 onto a new pc as the old one keeps crashing now so that will be a job for tomorrow! This will allow me to have directional control, but not manual speed control from the unit - only through mach3. It would be interesting to fit the speed feedback sensor into the system, but unsure if i can atm...

It seems that the issues have gone away now.

I have bought a spindlev4 board to control my spindle, then powered up my BOB with a PSU, and blew the microcontroller on the BOB handheld controller. The spindle board is fine as wasnt connected.

I then bought a new BOB which comes with the spindle output control and relay so im just going to fit that instead.
The Yaskawa relay will be bipassed for the time being (or maybe not depending on if i want to use it in the end). I am wiring in the new BOB and tested it.

Another thing i knew but forgot to remember was that mach3 doesnt like 64 bit machines, nor vista running 64bit, so a few days of tinkering and it was just the PC!
windows 7 32bit now installed and all running ok on a test motor.

Progress will be reported on in my blog, which i will link here when i have done it (although im sure i should rename this post to reflect it as a boxford 260 vmc retrofit)
