What sort of nothing?
If you look in "machine"->"show hal config" can you see the spindle

First set Pgain, Igain and Dgain to zero and adjust FF0 until you get
the speed correct at one rpm value.

Hi,
Just wondering if there's any experience with absolute encoders and
LinuxCNC?
And particularly absolute linear encoders, with or without LinuxCNC.
Thanks,

And what is the stroke? If it's 2 to 3.5 in, one encoder is enough.
Otherwise, as Chris says,
Hello!
Today I finally got an answer from Elte about motors and their current

The encoders have a resolution of 2um, so I don't think losing a few counts
should hurt me too badly. I've done a fair amount of testing to verify
repeatability and it looks very good. I used a custom "sample" component
yesterday to capture the two encoder counts on rising and falling edges

No, wire is *lots* cheaper than neodymium magnets. One carriage has
$75 worth of magnets, while a 6" set of coils uses about $7.50 worth of
wire. The AS5311 encoder chips are only $5 each. I really don't want
to have moving cables going to the carriage.

hi
is there proven spindle drive for fanuc spindle motor?
machine is working good but in case of problem i think it will be
better replace whole old fanuc 10m spindle drive.
i know servodynamc drives for axis, and do not know drives for spindle.
thanks

No, it is not called "dowel pin". I do not know the name, but that is
a cut on the outer surface of the shaft in axial direction of the
shaft. I even cannot

Possibly less that that.

If there is demand, it is probably not a difficult one to write.
Like a number of other components, the problem is having hardware to

What is the pwm scale? If that is 0-1 and your PID is 0-1000 then you
will have problems.
