Do these look familiar?

What do the Chinese use when they equip a servo driven machine with
encoders?? Surely they are not paying $50-60 per encoder?

I was having some issues with tuning servos with CUI encoder that are connected
to Geckos and talked with Mariss. He said the the mounting interface of the
CUI encoder can slip and has too much play (backlash) in it. He suggested
putting a drop of super glue on the edge of the plastic piece th

I think that Mariss started looking at those CUI encoders more than a
year ago as I recall reading on other lists..
I would listen to his advice as he tends to beat the heck out of things
finding out if they are suitable or not for his recommendation.

M1xx take two parameters already; I think they are P, Q.

Until the release is made, you could point them at the buildbot...

Hello everyone,
I asked the two questions written below on the forum at linuxcnc.org and
was advised that this group would be more likely to give me an answer.
I understand that the user defined commands M100 etc allow me to run an
external program but would it be possible to set up a command t

Yes, I have seen this on some samples of the CUI enc

Yep.
Hi,
I have two Chinese BLAC servomotors. They are equipped with (Tamagawa's)
something like:

I also bought one spare encoder from the manufacturer, price was RMB
370, about USD 57.
I have a little exp
Wow.
That is really cheap for a hollow shaft encoder. I wonder why someone
is not importing those to the US?? Or perhaps they are?

Hi Lars,
I walked a bit trough the code and tried some things out. There is already
cleanup code to avoid this problem, but the cleanup works only when emc is
started as root. It seems just like a problem with permissions. I recommend
to start emc as root to avoid the problems.
In case of proble

I also read that much of that stuff was removed in EMC2 to simplify it.

My idea was the first option - "G-code from some external source".
