I'm pretty sure it is a Teccor triac. Teccor is owned by Littlefuse now.

John,
Looks ok, but it may be something "simple".

I'm having a bit of difficulty getting my first attempt at changing machine
offsets for fixtures.
I have 9 locations that I want to machine the same things to.
1) Synopsys - start LinuxCNC. Home machine. touchoff G54 x/y/z.
2) Load in program.
3) Load first tool (collet chuck, manually done)

Do you mean it to have tapped 50% / 75% of hole's depth or do you mean
increasing the initial drill size so that height of actual thread profile
is 50% / 75%

At one time these encoders were known to have a latency issue. I'm not
sure what the current status is.

I've got a pretty good offer on a DM-4400. Too good offer to let it go...
It has closed loop steppers (surprised me) with gearboxes. It seems to be
in good condition but I am ready to give it new ballscrews and new motors
with direct feed or a 2:1 belt reduction and stronger steppers (more
speed).
When tapping in steel it is only necessary to have %50 thread depth and
%75 thread depth in soft materials.

That would be complicated to sort out what common metric drill sizes are
for each tap and much easier to just update the dictionary with a few
entries. I'm just not motivated to do either as I don't use metric drills.

Thanks, just don't use the metric option as the data for metric is still
in inch... I have no motivation to convert the few pitch entries in the
metric dictionary so if anyone does let me know.

Oh I forgot to mention I converted the first line of each type of tap as

I know most of you guys on the mailing list don't visit the forum so
here is a link to a G code generator for drilling and tapping holes on a
mill. I wrote this mainly because we don't have a tapping cycle and if I
forgot the pre-position move then you get a really neat show as your tap
