How-To Steps
Medium
1. Verify that the ATC’s Low Pressure Regulator is functioning correctly. If
necessary, increase the Low Pressure Regulator’s setpoint.
2. Test the spindle brake function:
a. Load an empty tool holder into the spindle.
WARNING!
The machine operates under automatic control — it can
start at any time and crush, cut, entangle, or pinch body
parts. Always keep clear of positions on the machine where
unexpected or unintended machine motion could cause harm.
b. From the PathPilot interface, in the
MDI Line
DRO field, type
M19 R0
(a
spindle orient command). Then select the
Enter
key.
With the brake engaged, the tool holder should be rigidly clamped, and the
spindle should not be able to rotate.
3. If the problem persists:
a. Push in the Emergency Stop button on the operator box, which removes
power to motion control.
b. Disconnect the compressed air supply from the machine.
c. Remove the Low Pressure Regulator and inspect the regulator’s ports for
damage or debris blocking the flow of compressed air. Clean and
reassemble the Low Pressure Regulator onto the ATC.
Then, repeat Step 2.
