Thanks for the kind words,

I think the kid really has some skills (but then I guess I'm a little partial?)
Already got my 'payback' guitar .. it's beautiful!
I tried to upload a pic but can't seem to get one to go through ..

I purchased a RS232 to RS485 converter from Grainger .. it uses 2 wire RS485 and I added a ground between the PC & VFD for good measure even though it worked without it. 
The Grainger part number is: 3AEA2

Sure ..

You might notice a difference between the .jpg file a few posts up and the .brn file attached below ..
I had copied another persons file & then tweaked it to work for me .. not being sure what the last line did I just left it in.
I've since removed it and the brain still seems to work just fine so until I figure out why I should need it, I'll do without it.

Thanks for the compliments,

The guitar business is my son's doing, I just built the CNC Router & a few other tools for him to use in his endeavor ..
I really don't know what the wait time is right now .. he might have something ready to ship for all I know.
Hope I'm not violating any policies on the forum here, but his name is Joel & his contact info is: jmarsh@marshguitars.com if you would like to investigate further.

Sinij kot,

I just went back to double check and my manual says: coil #1 is 0=off / 1=Run and coil #2 is 0=Rev / 1=Fwd .. meaning you have to command 1-1 to run in forward motion which is the way I have mine setup .. Perhaps my description of it is where the confusion is coming from.  After re-reading the way I described it my post of April 27th I made it sound like I'm using 0=Fwd .. Actually just case of bad communication on my part.

May be the case but after mucking around with this for so long & being so frustrated by it not working .. once I got to this place I wasn't too concerned about how it was wired.  It spins in the right direction when I give it an M3 command & it reverses when I give it an M4 command so as far as I'm concerned = it works!

I wasn't sure what to do with formulas either to be honest .. so I initially divided by a much higher number to avoid over revving the motor ..
I started with A/20 .. then from the MDI typed in M3 S1000 and used an infrared Tachometer to check the actual rpm of the motor ..
I kept changing the formula until the motor was spinning at the proper RPM for what was set with the MDI.
Now, with that said I need to also clarify that my spindle is belt driven and turns at twice the rpm of the motor when set for high RPM ..
So when I input a 'spindle speed' of 1000 RPM .. that's a 'motor speed' of 500 RPM.
Hope this makes sense .. not sure how else to explain it.
