Hi all,
recently I found stepper controller Linistepper which called my attention.
What do you think about it?
I am interested in running three unipolar steppers at currents about 3-5A per phase. I will use them for wood router. Currently I have build chopping controller based on L297 with FETs. I would like to drive my steppers at faster speeds with more torque. I think that Linistepper controller would eliminate resonance problems while using microstepping.
I see that it will be necessary to modify Linistepper - place more powerfull transistors, resistors and tune it up... I have skills and work with electronics, and want to do it myself. I have a scope which will be useful there.
Maybe someone allready done this?
Am I going right way? I know gecko drives, but they are too expensive for me now.
