Step 6: Install a Probing Pin
After connecting and homing the machine, you will be prompted to insert a tool. At this time, you can either install
a probing pin (to use the BitZero V2 to find job zero) or you can install an end mill. Typically, you will install an end
mill only after finding job zero.
To get ready to find job zero in the
first project, the Nomad 3 Starter Project, you’ll need to install the probing pin:
1.
Insert the
1
/
8
″
probing pin, included in the BitZero V2 kit, into the loose collet a minimum of 0.75
″
(20mm)
—
the entire length of the collet and nut.
2.
Hold the shaft of the spindle (above the threads) with one hand, while holding the probing pin in position
and tightening the collet nut with your other hand.
3.
Tighten the collet nut with your fingers, just until the probing pin will not fall out.
4.
Use the 13mm shaft wrench to hold the shaft of the spindle in place, while using the 17mm collet wrench
to tighten the collet nut and secure the probing pin.
5.
In Carbide Motion, hit the Resume button. The spindle will position above the BitSetter and will
automatically measure the length of the probing pin.
WARNING:
You can damage a collet if you compress it without support from the inside. This is also why
you should never tighten the collet nut without first inserting a tool, as you can damage the collet.
NOTE:
BitSetter is an automatic tool offset probe, which measures the length of each tool. BitSetter makes
it easy to run jobs using multiple tools without the need to stop and re-zero your Z-Axis manually. This
makes tool changes with the Nomad 3 simple and straight forward.
