This series of posts will show setting up a Hafco AL320G with a 3 axis DRO. The linear scales are Dalco low profile scales and an HXX GCS900-3D display unit. The linear glass scales just "do the business" where as the challenge is in the display unit. The GCS900-3D is not an expensive unit and from what I have seen it seems to be a reasonable option for the hobby user. My unit cost NZD135 delivered to my door. Hopefully these videos will give some ideas and save anyone using these units some time.
