DDSM50 Direct Drive Translation Stage

Chapter 5 Maintenance and Parts List

5.1 Maintenance

Over time, the glass encoder scale can become dirty. To prevent errors due to lost

encoder counts, the encoder scale should be cleaned periodically with isopropyl

alcohol and a cotton bud as follows:

1) Move the top platform to one end of its travel.
2) Moisten a cotton bud with Isopropyl alcohol.
3) Insert the cotton bud into the slot as shown above, and apply gentle pressure

downwards and sideways to push the bud against the encoder scale.

4) Move the cotton bud up and down the slot, along the exposed length of the

encoder.

5) Move the top platform to the opposite end of its carriage, and repeat the procedure

to clean the portion of the encoder now exposed.
