Hi
I have using Steppers and AC servos with Arduino for quite some time, without any library simply by pulsing the PULSE pin with digitalWrite HIGH/LOW. Recently, while using an AC servo, I realized that it is probably not the best way.
The servo is coupled to a roller set which feeds predefined length of a metallic strip to a processing unit. The feeding is done when a signal is received from a sensor. The problem I am facing is that the feed length is not consistent. After, say 3 or 4 times, the length would reduce by about a millimeter and then next few lengths would be OK and it goes on.
Looking for some guidance to rectify the issue or to some other approach.
