X-Axis scale is mounted off the back of the carriage
so there is no interference with the tailstock.
Both L-channel
mounts effectively protect the scales from impact, fluid & debris.
For my particular setup, the lathe is still the same distance from the wall as before the scale addition.
DRO is mounted onto wall. Its location positions the DRO
away from any cutting fluid spray.
When the
X-Axis scale is set to the diameter mode, its far
left decimal is on. The tachometer is indicating 637 RPM on the Z2
display.
The auxiliary port must be first set to ON in setup, then tachometer & SFM are activated using Functions 7
& 8, respectively.
Scales
directions & polarities must be
correctly defined in the DRO setup for
several of the functions to work properly.
All cable plugs are
held in place with a spot of hot glue.
Don't let any volatile liquids seep in behind the DRO's overlay, it might damage the
silkscreen.
I accidentally splashed mine with isopropyl alcohol while on the bench, causing
damage.
The overlay has since been replaced. It pulled off but it left quite a bit of
sticky residue
to remove since I had
I used the suggested (excellent) 3M Super 77 adhesive for mounting.
The newer display mount design allows better pivoting
positions & incorporates a cable tie strain relief.
Installed a galvanized steel extension plate to move the
light's magnetic base towards the back.
The plate is an electrical-box cover.
The arm pivots at both ends. Cement screws used as
wall fasteners.
Since the mount is so rigid, I did not bother to off-set the bracket like I did for the
Mill DRO.
Plugged fastener access holes with black, ⅝" diameter,
snap-in plastic caps. Cables are spiral wrapped for protection.
SPC cables are from
LMS. Adding a
deep red filter enhances the LED display contrast.
The five LED indicators have circular (punched) red filters, placed in the
enclosure cover, too.
I have the DRO plugged into a surge protector.
