i read it all but it is for an air cooled spindle and the most
important point relates only to air cooled fans etc. mine is water
cooled so i don't have to worry about that aspect. i assume you run
the cooling water all the time the machine is running even if the
spindle is stopped.
i still need to know the best way to control the speed if i decide i
want to. still don't know if mach3 will pwm the step or direction
pin assigned to spindle in ports and pins if i choose pwm control in
spindle setup. if so i just need to connect an FET driver to a
voltage source to get what i need for the voltage following input of
theVFD
still need to know if it is possible to have one spindle PWM
controlled and the other one on/off without PWM control.
?
and you will then be completely au fait
with all aspects of the VFD etc
