The X Axis Drive Assembly
7-50 DSX™ System Service Manual
7.6.6 Adjusting the X-, Y-, or Z- Motor Pulley and Idler Pulley
The Drive Motor Pulley and Idler Pulley must be properly positioned on their respective
shafts. Otherwise, the X-, Y-, or Z- Drive Belt may contact the edge of one or both pulleys
during operation.
1 Observe the Drive Motor Pulley while manually moving the drive back and forth
along the drive axis.
2 If the drive belt contacts the edge of the Drive Motor Pulley while the drive is
moved back and forth, stop at the point where the drive belt begins to contact the
edge of the pulley. Then, loosen the two M4 x 6mm cone screws that secure the
Drive Motor Pulley to the shaft, slide the pulley 2 mm away from the edge of the
belt, and retighten the two screws.
3 Perform an Arm self test by selecting DSX Manual Control from the Tools menu,
responding Yes to the prompt, and then selecting Arm in the left panel and Self-
Test the XY or Self-Test the Z (as appropriate) in the right panel. Then select Do
It to begin the test. During the test, observe the drive belt to determine if it rides
near the center of the pulley through its travel.
Note: Step 3 can be omitted if the system cannot be powered up at this
point.
4 Repeat Steps 2 and 3 until the belt rides near the center of the pulley. If the
results are satisfactory, replace the M4 x 6mm cone screws with new screws one
at a time, replacing and tightening the first screw before the second is replaced.
Important: The old M4 x 6mm cone screws must be replaced with new
screws. Use Loctite 222 on the new M4 x 6mm cone screws. .
5 Repeat Steps 1 through 4 for the Idler Pulley.
