Option 2: Carbide Motion Board Modification
Kit Option 2 includes a 6-pin BitRunner
connector which needs to be soldered onto
your existing Carbide Motion board. Use best
practices when soldering onto the PCB.
To modify the Carbide Motion board:
1.
Solder the male 6-pin BitRunner
connector to the board. Insert the
connector’s alignment peg and six (6)
solder pins into the six available thru-
holes on the right edge of the board. See
Figure 5
. The connector points away
from the enclosure (toward the FRONT
of the machine).
2.
Re-insert the modified board,
USB/power end first, into the enclosure.
The USB and power ports will slightly
protrude from the BACK (left) of the enclosure. The 6-pin BitRunner connector protrudes from the
FRONT (right).
3.
Use an SAE
3
/
32
-inch hex key and the four (4) existing socket head cap screws to secure the modified
Carbide Motion board to the enclosure.
4.
Use a 4mm hex key and two (2) M6x12mm button head cap screws to attach the enclosure to the
Y1-rail with the USB and power ports at the BACK and the 6-pin BitRunner connector at the FRONT.
5.
Reconnect the three (3) homing/proximity switch cables and four (4) stepper motor extension cables.
6.
Install the new enclosure cover included in the BitRunner kit and secure with existing hardware.
7.
Reconnect the power and USB cables at the rear of the Carbide Motion board.

WARNING:
The new 6-pin BitRunner connector protrudes from the front of the Carbide Motion board
enclosure. When installing the new cover, place it carefully over the BitRunner connector first, then bring it
down over the USB and power ports. If you should ever need to remove the cover, pry it open from the
USB/p
ower end first, then open like a book to avoid d
amaging the Bitrunner connector.
