HI all, hope you are doing well.
My question is it possible to build to make diy closed loop cnc machine?
Recently,I used rotary encoders with stepper motors(a NEMA 17 and a chinese optical quadrature encoder) and wrote a sketch to control the shaft position via strings recieved from USB. I used PID and stepperaccl library.
AFAIK,grbl doesn't support optical encoders feedback.So step missing might be an issue as i intend to use my cnc to mill aluminium. So i was wondering how hard it is going to be to write a g code decoder sketch for Universal G-code Sender along with my stepper control sketch to control a cnc.
Am i missing something? seems fairly possible to me.
forgive me for my noobness.
