Al the basic purpose of the charge pump is to keep the machine from moving if it is not reporting to mach3. Safety, safety, safety.

The parallel port on PC's give false signals during a PC's startup - the charge pump prevents false moves and spindle starts while booting the PC and before Mach3 has taken control of the parallel port.

Default HELP - Wiring C10, Charge Pump, and Spindle Control
Hello Everyone
Little background, I have a CNC router and I am using 5V from the computer power supply to power all the board (c10, Charge Pump, PWM Control board etc)
The problem i am having is when the computer is turned on the spindle starts and will run till mach 3 is open and the reset is pressed (Mach 3 takes control) and the spindle will turn off. As you can imagine this is a safety problem.
I do have a charge pump. (C4) that to my understanding detects a signal from Mach 3 and turns everything on once mach 3 takes control. The way i have it wired right now it works for all the servos, but it does not work for the spindle.
I can find wire guides for the charge pump to C10 and spindle control board to C10 but i cannot find a wire guide that includes all 3 of them. Can someone help me with the wiring of the 3 boards?
Thanks
Mike
So This Thread provides registry patches is to stop Windows from giving the parallel "false signals" during a PC's startup.
Safety issue or Not , YOU can decide.
But I think, if motor or spindle moves when MACH is NOT is control, it is UNSAFE.
