-===== 3.3.6 BlackBox X32 RC Servo =====
+====== 2.4 Connecting BLOX to RC Servo ======
-==== Wiring ====
 OpenBuilds BLOX provides support for using an RC servo to raise/lower a pen, in Pen Plotter type applications, or other imaginative uses
+===== 2.4.1 Wiring =====

-==== Configuration ====
+| GND | GND |
+| 5V | 5V IN |
-=== grblHAL ===
+| SIG | Servo Signal |
-Make sure to set $33=50 in grblHAL settings (CONTROL > Grbl Settings Tab > Scroll down to $33 Spindle PWM Frequency > Set the value to '50' and Save
-TIP: Set $33=50 (PWM frequency), $34=5, $35=5 and $36=10 to generate a "standard" PWM signal: 20ms repetition rate, 1 - 2ms pulse length range.
-You may decrease $34 and $35 to output a shorter pulse than 1ms at min, and increase $36 to get a longer pulse than 2ms at max.
-For most standard RC Servos that have moves 180 degrees when $34 and $35 are set to 2 and $36 to 15 - resulting in a 0.4 - 3ms pulse witdh range.
-=== Calibration ===
-OpenBuildsCONTROL includes a tool to calibrate the Pen Up /  Pen Down positions of your Servo.  Please perform this step prior to trying out the Pen Up / Down values, and also note down the S-Values as advised by the Calibration Tool to use in your CAM setups later on.
-Go to Wizards and Tools > Calibration > Calibrate Servo Pen Up / Down:

-=== Pen Control Buttons ===
-When $33 is set to 50hz, CONTROL will enable the Pen Up / Pen Down Buttons you can use to test you servo, check Pen Down positions to ensure your pen is touching the writing surface, etc
