Usar servo en eje Z
https://github.com/grbl/grbl/issues/220
There is a mod/fork of an old 0.8 grbl version which can use a servo on the Z-Axis:
https://github.com/heise/GRBLDRILL
It was done by the german ct magazin for a small PCB drill.
Unfortunately there is not much documentation about that, as far is i remember the servo does a full movement if you drive Z-Axis from 0 to +5mm via gcode. This can be changed somewhere in the code.
Just try the hex file from the github: https://github.com/heise/GRBLDRILL/blob/master/GRBL/grbl.hex
with a servo connected to analog4 on the Arduino.

GRBL Arduino Library – Use the Arduino IDE to flash GRBL directly to your Arduino
We have created an Arduino Library of the popular GRBL g-code Interpreter. A great little application that turns your Arduino into a very capable CNC machine.
This library makes it so much easier to install GRBL onto your Arduino. No more issues with making HEX files or trying to find a way to upload the Hex file to your board. Simply install the library and open the right example sketch for your Arduino.
How to install it:
- Down load the library from GitHub : https://github.com/Protoneer/GRBL-Arduino-Library/archive/master.zip
- Unzip the library and copy the main folder into the “Libraries” folder in the folder you installed your Arduino software. Eg. C:\arduino-1.0.3\libraries\
- Rename the folder to “GRBL”. (This will stop the Arduino IDE from complaining about the long folder name)
- Open up the Arduino IDE.
- Click on the following menu : File -> Examples – > GRBL (or what ever you renamed the folder to) -> ArduinoUno
- Upload the sketch to you Arduino UNO board.
If you are interested in the source code, its available at https://github.com/Protoneer/GRBL-Arduino-Library
