I am planning to use the charge pump to enable me to apply power to my cnc machine....hopping to not use battery ,,,,but not looking good...
ie start up mach3 ..which starts the charge pump .. which applys power to the machine....
While looking into doing this I found that I cannot use PIN 1 for charge pump ie pin 1 acts dead
??
I can use Pins 14,16,17 with no problem.... cable continuity on pin 1 is ok....
I will use an Mcode to power machine off....and yes I could use Mcode to power on
Not sure im my parallel port has a problem or not...
Is there anybody using pin 1 for charge pump...
I playing with the latest demo code....
