Motor bracket adjustment procedure

Fig. 1

1. Bolt A and B are used to move the motor across the track so the drive wheel is in the center of the outer flat surface of the table’s track.

Fig. 2
2. Bolt C (the one at the top of the photo) and bolt D, at the bottom, are used to set the angle of the drive wheel so it is flat relative to the track. The goal of the adjustment is to set the drive wheel just above the surface of the table track – so you can see daylight between the wheel and the track, as shown on Fig. 2.
1. Loosen bolts C and D about one turn.
2. Gradually tighten bolts A and B, a little at a time, to lower the drive wheel towards the track – it may help to lift the motor slightly to take the weight off the bolts.
3. When it is in about the right position (that is, the drive wheel is about a hair’s breadth off the table track), look and see if the metal plate is level at each end – adjust as required.
4. Check the Sensor Wheel and the drive wheel are in the centre of the outer half the table track and they are in line down the middle of the track (or as close as possible).
5. Screw bolt C down to the point where it just touches the lower plate.
6. Screw bolt D down to the point where it just touches the lower plate.
7. Fit the Allen key into bolt C and looking at the drive wheel from under the motor – tighten blot C very slightly – you may see the drive wheel lift a little – if you tighten too much, you may see the whole motor twist inwards and go away from its straight line down the middle of the track.
8. Fit the Allen key into bolt D and and looking at the drive wheel from under the motor – tighten bolt D very slightly – you may see the drive wheel lift a little – stop at that point. Check whether you can see daylight under the wheel and check the drive wheel and Sensor Wheel are still properly aligned.
9. Tighten bolt C again a little more – about ¼ of a turn.
10. Check you can see daylight under the wheel and check the drive wheel and Sensor Wheel are still properly aligned.
11. Tighten bolt D again – about ¼ of a turn.
12. Check you can see daylight under the wheel and check the drive wheel and Sensor Wheel are still properly aligned.
13. Keep alternating between the bolts until C and D are very tight.
14. Check you can see daylight under the wheel and check the drive wheel and Sensor Wheel are still properly aligned.
15. Tight bolts A and B, a little at a time until each is very tight.
16. Check you can see daylight under the wheel and check the drive wheel and Sensor Wheel are still properly aligned.
