in order to control the speed of a spindle with a PWM signal you need a controller that will accept a PWM signal,
or effectively, a 0-10V siganl and control the motor speed. Do you have such a device? If MACH3 doesnt count then no i do not have any such device .
Second question is 'do you need it?'. With the current speed i had to lower my acceleration and velocity so low so that it doesnt break the marble. it took almost 2 hours to complete a 1500 line gcode. where as it takes only 10 minutes on a wooden peice.
Most of the time my mini-mill sits at 24000rpm and stays there all day. I can control
the speed both manually and programmatically but I seldom need to. I imagine you'll be running your diamond tools at a constant
Yes i will be running it at a constant speed but i want it to be the max speed so i can move the machine a little faster.
so is there any way i can make it work at its max speed without PWM supply?
like with the 24 supply i have provided it.
