With program MACH3 the code M47 repeat program. We add the draw of our work.
¿How we can make a repetitive program with controleer BCNC?
And in this program, ¿how can we number the program lines?
Can we take advantage of the “exits” inputs-outputs of the raspberry?
Is it possible to find an extensed manual with programming examples?
With the raspberry and the protoneer plate, ¿can we operate servo motors with the same pulses that we use for stepper motor?
Do you mean PWM Servos like that one, right? https://amzn.to/2JRUrk4
The A4988 or DRV8825 Stepper Drivers were not designed to do so but if you have an oscilloscope you would be able to create a PWM Signal which is controling a Servo, but I would recommend using an unused pin of the Atmega which is still soldered on the board and modifying the GRBL Firmware or using one of the RPi GPIOs.
