Got a sweet Leblond Tool & Diemaker lathe last week from HGR Surplus in
Euclid, Ohio. The Mitutoyo y axis scale reader head has its' signal
wires pulled off the heads' circuit board. Might anyone have the color
code diagram for one of these heads? No model # on the assembly - looks
like late 70's or early 80's vintage. Called Mitutoyo, they won't fix it
- obsolete based on pictures emailed - but will supply me with a modern
replacement for $325.00. Shame to waste $ for some pulled out wires...
Any help would be appreciated.

Assuming it has a Y axis DRO of the same vintage/make, the colour
codes SHOULD be the same....put the covers off, have a look

The X axis is different than y axis.

??? Where ???

If the reader heads of the X and Y scales appear to be nearly identical,
removing the small cover from the scale that is working could very likely
reveal the wiring order on the one with the pulled wires.
If the little covers have sealant applied to them, cleaning off the old
sealer and replacing it with some new sealer should insure that liquid
drippage will be kept out of the reader head housings.

Checking the individual leads for continuity while flexing and rolling the
lead bundle slightly with your fingertips could confirm that there aren't
any other intermittent breaks in the cable leads before concluding that the
repair is finished.

Hey Steve,

I would expect them to go on in the same order as they "lay". Looking
at your pix, the blue wire is still attached, and all the wires appear
to be still "trapped". I'd re-solder in that order.

Take care.

What model of display box does it have? I have a
DRO called a "PL Counter" with two
different styles of scales on it. A "standard"
scale on the Z, and a "mini" scale on the X.

Your box sounds like the one I have - 325 PL. Mine has the mini scale on
the y axis.

Ugh. The problem is it is quite involved to get
the scale off the machine and back on and properly
aligned. As you've discovered, they are also a
bit delicate, so there is some possibility of
damage in taking it all apart. So, I'm kind of
hesitant to take mine apart to get a look at the
wire ordering. I hope somebody else has one off a
machine to look at.

Oh, yeah, the "Y" business. Mine is labeled "Y"
also, but by definition, it should be Z for the
carriage and X for the cross slide.
