Mount Tool Bar
ATC toolbars are shipped pre-assembled. There are three different toolbar lengths, corresponding to 48”,
60”, and 72” wide tools. The toolbar is installed at the rear of the tool, and provides a mounting location for
tool holder clips and fixed Z-zero plate. Toolbars include six tool holders standard. Bit diameter should not
exceed 1.25” and total bit length should not exceed 5”.
To mount the toolbar, use a 1/2” wrench to loosen the 4 hex cap screws connecting each of the two toolbar
brackets such that they can be adjusted to span between the table sides. Slide T-nuts into the 4 inner slots
of the table side. Toolbar brackets should be mounted 12.5” from the table end, as per the drawing on page
7. Before tightening, level the tool bar by placing a level on top of the extrusion in both directions (along X-
axis and Y-axis of table) to ensure that the tool bar and table sides are aligned.
Note:
Before fully tightening the mounting bolts, turn on the machine and move the gantry to the positive x
extreme to ensure that the spindle will reach the toolbar without hitting the mechanical stops. Mechanical
stops should be positioned such that the center of the rear gantry v-wheel’s center reaches a minimum of
0.125” from the end of the rail.
The Fixed Z-zero plate can now be wired directly
into the control box using the attached 2
conductor cable. Connect the cable to the plate
with the attached WAGO connector and wire the
black and red wires into ground and input 1 (ZZ)
respectively on the control board.
