The specification says
54.2 oz-in rated torque and 266 peak (0.4 resp 1.9 Nm). Could it be that
they are too small?
Possibly, I had 2.5Nm steppers on my mini-mill and upgraded to 4Nm

Is it possible that this really annoying problem be too small motors?
It shouldn't be with an encoder-equipped system, as any deviation from
commanded position should trigger a follow error.
However, perhaps such an error is being raised by the drive

Well,
the figures do not compute, the spec tells me it's 18.2V 11A which would
be max. 200 W.
But I thing 0.4 Nm is very low for this wattage.
As the spec also tells me it is meant for applications such as carriage
of high speed printers and XY plotters.
IMHO these are too small for a CNC

They overshoot with no load at all.
So, the good news is that they are probably big enough for the job, as
they behave similarly under load and no-load, and have successfully
Whether this will mean anything for folks like us who need a high speed,
_low latency_ I/O connection will depend upon the details of the
controller:

My instant reaction is that they are very inefficient. I would call that

lots of geardown, would be a bit small for a

HI all,
This was from Andy's inquiry of a couple days ago. It appears that the
documentation for the debounce component in the Integrator Manual (Page
94) has a slight error or typo. The syntax as written does not work for me,
i.e.:
halcmd loadrt debounce 1 4 2
but
halcmd loadrt debounce 1,4,2

To me, these eBay-items looks
pretty small too. Are they really going to make it?
Good question, they are rated 50% more torque than your servos. Your
servos are a much higher-quality solution, if
Rob,
I'd be interested. I am planning to go to the Exhibition probably on the
Saturday.

I am catching up on my EMAIL, and I've still got 10 EMC digests to read, but I
wanted to comment on the quote below. This gives the impression that you are
setting the PID values for the servo motor on the bench with nothing attached.
This is not a good idea since these settings SHOULD be

Hm,
I don't have access to my EMC system right now, but the webserve also
runs Ubuntu, it does accept the ~ on the commandline -
as you can also see from the error in Aram's mail (Error: file TR2~ - No
such ...).
Maybe there are unprintable characters in the filename?
You could try name
