===E-STOP===
In case of emergency, stop the ShopBot using one of three methods:


*E-STOP button on the remote. This will immediately cut all power to the ShopBot. The tool will spin down naturally. E-STOP is a good default option.
*Press the Spacebar. This will lift the tool up and apply the brake. This is a good option in less urgent situations, like needing to adjust the zero positions.
*Click the mouse. When the job starts, the mouse will automatically lock onto the stop button. Pressing any button on the mouse will stop the job in the same way as the spacebar.

TIP: After a cut operation, the ShopBot will move to the “Z Safe height” before moving rapidly to its next position. When using clamps or other fixturing, adjust the Z Safe Height in the CAM software such that the Z safe height is above the clamp or fixture.

==== Assembly ====
==== Assembly ====
1. Clean components with compressed air.
*Debris caught in the tool holder can cause the tool to slip, damaging the tool and equipment.

<div style="clear: both"></div>
2. Insert the collet into the nut.
*Put the collet on the table and the nut on top.
*Press on the nut until the collet snaps in place.
[[File:Nf16colletbuild.jpg|thumb|200x200px|left|Load the collet into the nut]]
<div style="clear: both"></div>

[[File:Nf17collettight.jpg|thumb|200x200px|left|Loosely tighten the collet]]
<div style="clear: both"></div>
4. Insert the tool.
*Do not tighten on the flutes
*Make sure enough of the shank is in the collet to properly hold the tool - tool should fill ~80% of the length of the collet.
[[File:Nf18toolin.jpg|thumb|200x200px|left|Insert the tool]]
<div style="clear: both"></div>
Load the collet into the fixture:
*Press and hold the top knob
*Insert the holder; rotate and push until it's fully inserted
*Shoulder must be flush with the face of the fixture
[[File:Nf19colletfix.jpg|thumb|200x200px|left|Load the collet into the fixture]]
<div style="clear: both"></div>
5. Tighten the collet nut.
*Ensure all four teeth on the wrench are engaged
*Tighten the nut until the table lifts from the floor
[[File:Nf20wrench.jpg|thumb|200x200px|left|Tighten the collet nut]]
<div style="clear: both"></div>
6. Load the tool into the ShopBot

=== Zeroing Axes ===
=== Zeroing Axes ===


==== XY Zero ====
==== XY Zero ====
XY axes are set manually (moving the tool to the desired home position).
1. Open the Key Pad.
[[File:Nf8keypad.jpg|thumb|200x200px|left|Open KeyPad]]
<div style="clear: both"></div>
2. Use the arrow keys to move the head to the desired home point.
[[File:Nf9arrow.jpg|thumb|200x200px|left|Use arrow keys to move]]
<div style="clear: both"></div>
3. Select ZERO AXES.
[[File:Nf22zeroaxes.jpg|thumb|200x200px|left|Zero Axes]]
<div style="clear: both"></div>
4. Check "X-Axis" and "Y-Axis" then press ZERO
[[File:Nf23xyzero.jpg|thumb|200x200px|left|XY Zero]]
<div style="clear: both"></div>


==== Z Zero ====
==== Z Zero ====
Z zero is done automatically with the Z zero routine.
1. Attach the Z zero fixture.
*Attach the clip to the collet nut or the tool
*Place the plate on the spoilboard or the top of the material, depending on how your file was programmed
[[File:Nf24zclip.jpg|thumb|200x200px|left|Z-axis zero clip]]
<div style="clear: both"></div>
2. Check the connection for continuity.
*Lift the plate and tap it against the tool. If input #1 flashes on screen, the connection is good. If input #1 does not flash, adjust the clip and retry.
[[File:Nf25testconnect.jpg|thumb|200x200px|left|Test Connection]]
<div style="clear: both"></div>
3. Run the Z zero routine
*Tool will tap twice against the plate
*Watch the Z axis readout: if it continues scrolling downwards without stopping, the ShopBot has not detected the end of the tool. You must stop the routine and try again.
[[File:Nf26zroutine.jpg|thumb|200x200px|left|Z zero routine]]
<div style="clear: both"></div>
4. Remove and store the fixture.
*Plate goes in the 3D printed holder
*Clip attaches to the frame
*Make sure the clip is not touching the plate

<div style="clear: both"></div>


=== Spindle RPM Check ===
=== Spindle RPM Check ===
Occasionally, the ShopBot does not read the RPM from the file correctly. Other users may also have adjusted the default RPM away from 18,000. Use this method to manually enter the RPM.
1. Select Tools, then Spindle RPM Control
[[File:Nf28RPMcheck.jpg|thumb|200x200px|left|Spindle RPM check]]
<div style="clear: both"></div>
2. Click to the left of the word PREVIEW
