Safety Precautions and Warnings
BobsCNC Routers have a 110 v. Power Supply and use bits that spin at 30,000
rpm with cutting edges that are sharp and hazardous. The operator must
understand the potential hazards and is responsible to take appropriate
safety precautions before operating the Router.
•Only use extension cords rated for 20 amps plugged into a dedicated
outlet.
•Inspect the machine before every use for maintenance issues: loose
fasteners, belts, etc.
•Do not operate the machine with dull or damaged router bits.
•Always unplug machine after each use and when cleaning the router or
changing router bits.
•Remove rings, bracelets, watches, necklaces before using the machine.
•Wear snug fitting clothing and/or roll up long sleeves to prevent snagging.
•Use appropriate personal protective equipment (PPE) when operating
machine including safety glasses and hearing protection.
•Keep hands, hair and clothing away from the moving parts of the machine.
•Do not operate the machine when under the influence of alcohol or
prescription medications.
•Make certain the workpiece is clamped securely in place before starting
the machine.
•Never leave the machine running unattended.
•Children must be supervised by adults when operating the machine.
•Do not operate the machine in the presence of flammable materials.
•Keep floors clean, dry, and free of debris to eliminate slip and/or trip
hazards.
•Have a suitably rated fire extinguisher on hand when the machine is in
operation.

Getting Started
Required Tools to Assemble the Quantum CNC Kit:
Metric Socket Set
#1, #2 and #3 Phillips Screw Drivers
Needle Nose Pliers
Set of Metric Allen Wrenches
Pliers
Utility Knife
Clear Nail Polish or LOCTITE 242
Scissors
Blue Painter’s Tape
To Operate the BobsCNC Quantum CNC Router, you need will need:
Computer with control software for GRBL.
Materials for Projects.
1/4” Shaft Router bits.
Recommended for the electronic setup include:
Multimeter to correctly connect the Power Supply and to set the
current for the Stepper Motors (a great tool for general electronic
trouble shooting).

Assembly Recommendations:
Use a large, flat, clean work surface for assembling your Quantum
Max.
All Screws (unless noted) should be installed snug, then rotated 1-2
½ turns.
Apply LOCTITE 242™or clear fingernail polish to all M4 X 16 mm
Machine Screws that are used to secure plywood pieces. Machine
Screws that are secured with Lock Nuts do not need LOCTITE™.
Light sanding of the wood components may be performed if desired.
Painting or applying stain with a clear coat will provide extra
protection to the wood components.
Clean the rails with acetone to remove rust preventative and apply a
light coat of PTFE (Teflon®) lubricant.
We recommend using strips of 1-inch blue painter’s tape behind the
T-Slots to help hold the Nuts in place during assembly.
Lock Nuts are never used to secure components that have T-Slots.
They are only used to mount components where the Nut is not
held in a T-Slot.
CAUTION This kit contains numerous small
components that pose a choking risk for small
children and pets. Keep kit pieces in a secure
location out of the reach of small children and
pets.

Illustrated Step by Step Instructions
Step 1 Attach two Extension Frame Supports to Quantum Frame.
Step 1a Attach two Extension Frame Corner Supports
(EQX8) on the Torsion Arms (QX2). Note the
notch in the Corner Support should be
oriented toward the front and the center of
the Assembly.
Step 2a Align the slots in the Frame Corner Supports
(QX8) with the tabs on the Torsion Arms
(QX2). Slide in place and secure with four M4
x 16 Machine Screws. Repeat for each of the
corners.
Only install the top Supports. The Bottom
Supports will be installed in a later step.

.
Step 2 The following steps will cover building the Front X Frame
Assembly.

WARNING There are two long and two
short Torsion Arms in the Max Front X-Frame
Assembly. The long Torsion Arms are located
on the front of the Assembly. The short
Torsion Arms are located at the rear of the
Assembly.
Step 2a Use strips of painter’s tape to cover all the T-Slot
cutouts in each of the four Torsion Arms (QX2 and,
EQX2) and Torsion Plates (QX9) as shown.

19
Step 2b Turn the Torsion Arms over and install a M4 Nut in
each of the T-Slots as shown below.
Cover the installed M4 Nuts with strips of painter’s
tape.
This will hold the nuts in place to make it easier to
connect the Torsion Arms (QX2 and EQX2) to the
Torsion Plate (QX9).
Step 2c Align the tab of the Torsion arm (QX2) with the
corresponding slot in the Torsion Plate (QX9).
Notice how the rectangular notch is oriented. Make
sure the cutout in each of the arms is oriented in the
same way in the Assembly.
