Hello!
I have some steppers with a low coil resistance, right now I run them with some 12 ohm 50W series resistors, but it seems like a waste of energy.
Is it possible to adjust the PWM duty cycle somewhere from software?
I have roamed aroung the Live CD but couldn't find it in the reprap program menus...
I searched the PIC code and found some variable called "CCPR1L" with a default value of 4, which according to comments was 25%.
With my about 1 ohm coil and a 12 V power I should need about 5% duty cycle
to get about 0.6 amps.
Any hints would be helpful!!!
