Chineese 6040 problems

I cannot get the spindle to spin under computer control even when running gcode.

Did it say you could in the instructions ?

Eddy, there is some confusion from Kendrick here - I have spoken to K on the telephone and he has a 400hz vfd and a 24k spindle. I do not think that he can control the spindle speed with his software (only from the vfd and he is quite happy with that), he is unable to stop/start the spindle and I think he should be able to do that if someone can advise him. I can't help because I use dedicated controllers on both of my machines (commercial system, not mac), but I am sure someone on here can point him in the right direction. G.

Starting/stopping the spindle is often done using a output which controls a 5V Relay who's contacts connect to the VFD run Signal.
Often the BOB will have Dedicated on board relay connected to output.

Reason for the Relay is that the VFD run signal will probably be 24V so can't be directly controlled using the 5v Output.

Have a look in here; http://www.mycncuk.com/forums/227-Ro...es-Controllers top two posts look promising.

and this could be the vfd manual; https://drive.google.com/file/d/0B4P...kxJ/edit?pli=1

The second link gives me an idea as to what I should find when I finally take the to off the is that black box called a Bob.
the third link looks promising the control panel is identical,have not read it all yet.

No the BOB is short for break out board. That second link showing the Guts isn't what you have because it shows a USB Motion control card and you had Parallel port based box. The BOB will look very similair to the USB card in the picture.

NOW BE WARNED.!! Messing around with BOB without knowing the pinout and numbers is sure fire way to KILL it.!!
BOB's and esp a cheap one that will undoubtly be inside this box are fickle creatures at best of times so don't mess unless your sure what your doing.
