I have built a CNC plotter machine and in the metal gear servo motor, when I have a code from UGS like M03 S80, it gives a continuous tick tick sound. But not rotating. if I give a small push from my hand, then only its rotating to 80 degrees. if we put M05 S10 code, that also the same.
My i know the reason for it?. It worked perfectly previously. But from now its giving some sound without any movement. The spring i use in the pen gives some friction. Is it the issue for this?
