In the case that the Beaglebone board needs to be replaced on a Pocket NC V2 series machine, it is best to follow the steps below to ensure proper removal and installation.

Step 1: Remove the Beaglebone Board

Step 2: Re-install the Beaglebone Board

Step 3: Check Spindle Voltage

If your machine has a main circuit board labeled “Pocket NC V2 Board Rev. 0.1.0” or higher (circled in red below), the machine’s SPINDLE_HIGH_VOLTAGE value should be checked.

Depending on the age of the machine, this value may need to be changed. V2-10 machines should have a value of 2.7888 and V2-50 machines should have a value of 3.3572. To check and change the spindle voltage, follow the steps in the videos below.

If the SPINDLE_HIGH_VOLTAGE field does not show up under the POCKETNC section on your machine, it is likely that the value needs to be changed. (If at any point in LinuxCNC it asks for a username or password, enter “default” for both).

The value shown in the above video is simply a place holder. Remember to use the value required for your version of machine.

V2-10: 2.7888

V2-50: 3.3572
