Topic: liquid sky laserjet M56750fp brushless driver help needed (Read 1 time) previous topic - next topic



I'd like to use the polygon stepper mirror from a laserjet printer for a simple laser projector for liquid sky effects. The stepper driver is an M56750 fp with 4 inputs, lead 1 V+ 2 pin 5 accel 3 pin 6 decel and 4 ground,

the driver pdf is here http://www.datasheetcatalog.org/datasheet2/a/0a92y8fji8ri01xlwcxr5w1ug7py.pdf.

I don't have a clue how to possibly program an arduino to make it go though, any help would be much appreciated




If you are going to use it like a liquid sky effect, you must keep in mind that you lose a lot of the light this way, unless you want it to be just as wide as the deflection on a whole turn of the mirror face.

Try connecting up power and ground the Accel. pin, then it should run at maximum speed.
