Machine Axes

This machine is a 3-axis machine, meaning it moves in three distinct directions. The three axes are as follows:

🟩Y-axis: Positive Y is forwards, negative Y is backwards
🟥X-axis: Positive X is to the right, negative X is to the left
🟦Z-axis: Positive Z is up, negative Z is down

It's important to know which axis is which direction for things like jogging the machine (see Mach4 for more information on jogging) and visualizing your toolpaths

Workholding/Fixturing

Our CNC Router's bed is designed with several options for workholding, these are:

🟥Good points to use wood screws
🟩5/16-18 Bolts used to attach the MDF to the extrusion below, should NOT be used to attach stock
🟦Open T-slot rails

Fixturing Options

3D Printed Clamps: Open T-slot rails (🟦) can be used to mount a variety of 3D printed clamps. View the Clamp Library for more information
Wood Screws Through Bolt Holes: For a part with holes cut in it for bolts, you can pause the machine after the holes are cut out to drive wood screws into the MDF. Just make sure to remove them when you want to remove your part

Changing Tools

Performing a tool change is pretty simple, see timestamp 4:31 in the attached video for a visual reference, or follow the steps below.

Required Tools

Two crescent wrenches (located in the toolbox under the CNC)
- Large wrench (fits the black spindle nut)
- Small wrench (fits the flat of the silver spindle shaft)

Steps

Grip the spindle
- Place the large wrench on the black spindle nut
- Place the small wrench on the flat of the silver spindle shaft
Loosen the collet
- Rotate the large wrench counterclockwise (looking down)
- Rotate the bottom wrench clockwise
  (These motions should turn the wrenches away from each other)
Swap the tool
- Remove the old tool from the collet
- Place the new tool in the collet, making sure it's straight and has the proper stick-out (see Tooling Overview)
Tighten the collet
- Rotate the large wrench clockwise
- Rotate the small wrench counterclockwise
  (These motions should turn the wrenches toward each other)
