So the situation is this:  I have a mach 3 running a cnc gantry style and I have added a forth axis (A axis)  It has its own power supply and control board.

My spindle runs separately and it is not controlled by mach 3.  I turn it on manually.  There are no wires running from the inverter vfd that runs the spindle, and control board--none!. So the vfd, spindle electrical cable, and spindle are not wired to the control board that runs a-axis or to the other control board that runs any other stepper motor!.  A-axis lathe is run by a stepper driver and stepper motor.

But the following happens: When the spindle is activated by turning on the vfd ---the A-axis rotary starts turning, but it sounds like its grumbling badly as it spins up to rapid.  Its not suppose to do anything.  If I disconnect the usb cable between the A-axis control board and the computer, and then start the spindle running, then A-axis does nothing.  Plug it back in with the spindle already running--and a-axis revs back up, grumbling.  Actually its sounds like a growling cat or something tearing itself apart.  If I disconnect the energy cable from the spindle motor, a=axis still turns (vfd still turned on).

IF I EXIT MACH 3 ALTOGETHER... AND THEN TURN ON THE VFD, THE A-AXIS still SPINS UP!! 

Hitting the emergency switch, stops x-y-z movement, but the *7!@# lathe keeps on turning...(its alive!!)
Hitting the home switch for a-axis does nothing... still keeps turning.

Ok you wizards... where did I f*** up.  bob

Rich--or Dude1

With the 062 version of mach 3... should I totally uninstall the previous 066 version and all that, or can I just load 062 and it would it work just to over-ride the 066 ???

Rich or Dude1,

I tried the address    http://ftp://ftp.machsupport.com/Mach3/  on a windows xp computer, a windows 7 computer and my wife's windows 10 computer... this address showed either "page not available", or just listed several New Fangled Solutions sites.  The only version on the regular New Fangled Solutions website of Mach 3 downloads is version ending with .066    So is there another way to get version ending with .062 ??  bob

Gary I don't have this problem with rosewood--that is chip problems.  I use a carbine 4 flue downcutting endmill made for machining metals, and it works fine on rosewoods from my experience.  I do work ebony as well for the fretboards, but that machines well enough too.

For Rich.  Is there a way in Mach 3, to print the screen clearly.  I usually use snipping tool, but xp does not have that feature.  I would like to print out all of my setup screens in Mach 3 before I start changing settings around as you have asked for my learning the better way of working...bob
