And when you have a S0 in my board you just have 0 volts, 0 amperes in the coil, the spring and the magnets just pull it up , you dont need iddle , you are using PWM , 0 volts means zero warming, zero iddle .
When you have S1000 you have full voltage in 'x' milliseconds derived from HZ , so you can have up to 5 small impacts in each pixel , so, if I apply 10 vcc in my lm-298 it will cause the coil to impact 5 times the pixel at 10 vcc , this 10 vcc comes from a dc-dc downloader , if i put 5 vcc it will be the maximun , but if I am doing basalt , i will input even 15 vcc.
My best results in granite are with 10 vcc , and 1 karat diamonds , if you look carefully you will see that i dis a screw on the body of the diamond ( 6 mm thread) and I have two nuts in the point of the lever, so I can adjust the height of the diamond refering to the granite , this is very important, a long course will get the job slow , I put it to 1,2 to 2 mm according to material.
