ATC Installation (Mechanical)
This section assumes that, except for the table assembly (a drawing for this is provided under “Table
drawing”), the ShopBot has been assembled using the instructions provided in the ShopBot assembly
manual. This means that the ShopBot is at a point in which it is able to connect and move under the
control of a computer. Wire/cable management may be left until the ATC installation has been com-
pleted.
VERY IMPORTANT! For New Table Setups
The location of the table bed is extremely critical for ATC. Excess overages in the X dimension could
mean tooling collisions, insufficient cutting area, and dropped tooling. At the end of this section there
is a table drawing that shows how the table should be set up. Pay close attention to the relationship
between table sides and the table surface.
For Previously Assembled Tables
Loosen the bolts that are attached to the table side extrusions and slide table sides in the positive X
direction until the table is in the position called out in the table drawings at the end of this section.
Mounting the Spindle
The ShopBot ATC is equipped with a 5HP HSD spindle. The spindle
is cooled by an electric fan, but also has air-cooled lower bearings.
The air required for cooling the lower bearings is 60 psi (4 bar).
The spindle also has an internal drawbar that holds the tool cones in
place during cutting; this requires 90-100 psi (6-7 bar).
Power up the ShopBot and position the YZ car so that it is in a
location where the front and back of the Z-axis may be reached.
Use the keypad mode (K) on the computer to move the Z-axis to a
height close to the table’s surface.
Rest the spindle on its end as seen to the left. Position the Z-axis
up or down using the keypad mode again until the holes in the
Z-axis align with the mounting holes in the spindle plate.
Tighten spindle securely to Z-axis with six 5/16” x 1 1/2” socket
head screws.
