Method 1: VHB Tape (Not Included)
Use a high-quality, double-sided, multi-purpose acrylic tape, with a service temperature of up to 200F, such
as 3M Scotch RP45 VHB Tape.
1.
Clean the back of the BitRunner enclosure AND the outside of the Y2-rail (roughly in the center) with
rubbing alcohol or mineral spirits. Both must be free from contaminates for maximum adhesion.
2.
Apply two strips of VHB tape lengthwise to the back of the BitRunner: one across the top and bottom.
3.
Peel the backing from the VHB tape, position the BitRunner with the LED on TOP, and adhere it
squarely to the center of the Y2-rail.
4.
Apply a set of clamps to the BitRunner, ensuring even pressure across the face.
5.
Leave clamps in place for at least 15 minutes.
Method 2: Drill / Tap
1.
Hold the notched-side of the BitRunner squarely against the outside of the Y2-rail (roughly in the
center) and use it as a template to locate the position of the tap holes.
2.
Use a center punch or transfer punch to mark the Y2-rail at the center of each notch. The center-to-
center distance between mounting holes is 6.10" (155mm).
3.
Use a 5mm drill bit for the tap hole and an M6 tap to form the threads. Be sure to drill all the way
through the outer wall of the extrusion and into the cavity.
4.
Use a 4mm hex key and two (2) M6x12mm button head cap screws (included) to secure the
BitRunner to the Y2-rail with the LED on TOP.
Carbide Motion Board and Enclosure Upgrade
For late 2019 and earlier Shapeoko models (pre-Z-Plus), there are two options for upgrading the Carbide
Motion board. The option you choose will depend on which BitRunner Kit you ordered.
Option 1 is a complete replacement of the Carbide Motion board and enclosure cover. Option 2 is a
modification to the existing Carbide Motion board and a replacement of the enclosure cover.
PRO TIP:
A good mark from
the center punch will prevent your drill bit straying from its mark. Pre-drill your
tap hole with a 3mm bit first, then step up to the 5mm bit.
NOTE:
VHB tape is pressure activated. To permanently bond to the extrusion rail, you must use clamps.
WARNING:
The “Carbide Motion
b
oard” is the printed circuit board (PCB) that shipped with your Shapeoko.
It is located in the black enclosure attached to the Y1-rail (Shapeoko XXL & XL) or the X-rail (Shapeoko 3).
Do not confuse it with the BitRunner’s PCB. Do not open the BitRunner o
r modify its PCB in any way.
