Hi,
i have this spindle from aliexpress https://www.aliexpress.com/item/NEW-Spindle-the-CNC-Spindle-Motor-ER11-500W-52mm-mounting-bracket-spindle-clamp-for-PCB-engraving/32341330193.html i would like to get it on my x-carve.
It is possible to use this http://www.bristolwatch.com/ele2/dac.htm to control the speed of the spindle?
From my point of view it should work, after all it converts the PWM signal from arduino to 0-10V accepted by the power source but im not very good at electronic circuits.
Thank You.
