[login to view URL] I have modified GRBL to suite our needs for a motor driving application It works really well. the linear drive i am driving has a linear pot. I have hooked it up and i'm able to read from it but if i do that it messes up the moving motor so i can only read when the motor is stopped. I figure GRBL must be able to read an ADC value successfully while driving because i belie...
