General Mach Discussion / Re: Converting from ncstudio
« on: November 15, 2015, 07:50:31 AM »
Thanks I have watched that about 20 times in the past few weeks, he really does not show anything useful. If I get stumped I can use the vfd panel to control the speed as I dont need to change speed midflight, it just would have been nice. Generally I only ask a forum if I cant find the info myself. So far I am guessing that the blue/yellow/red wires supply the signal for low/med/high which is grounded back to the board via the green from FWD, so if use the red (maybe blue)& green on the spindle on/off circuit on the new board, that may work,.. if you follow.

I need some help connecting mach3 board to vfd.
The new board has a spindle on/off and 0-10v PWM

the old board had 4 wires going to the vfd green  - fwd and ACM
                                                             blue    - M11
                                                             yellow - M12
                                                             red     - M13
In ncstudio spindle speed was 2400, 1200 or off ( you could enter whatever speed you liked but it only did off, fast and very fast)

any ideas  on how I wire this?
