Hi Sergey,

They also do some nice servo drivers though they are step/direction so
you can't use the encoders as a DRO.
Steppers do work and can be

My EMC machine rarely needs internet connectivity so the flash drive works
fairly well for getting gcode into the machine. I'd much rather have a

Personally I would go one step farther. I want torque or velocity mode
system and not a position mode (step/dir) motion
I do this on my lathe. I use a LED/sensor out of an old ball mouse with
a semicircular flag on the motor that is about 1.5 diameter. The output
of the sensor is open collector(switches to ground). This is in parallel
with the home switch. The home switch is normally closed.

I saw some post that there was a fix with the RTAPI or something.

And rebooted a couple of times along the way.

If anyone would like to take a look at the print set I put together for my Sieg
(Grizzly G0463) X3 mill CNC conversion and critique it I'd be EXTREMELY
appreciative - I'm not schooled in mechanical drawing (I work for a dreaded
architect...) so anything that doesn't make sense being pointed out
Might help if I include the link -

Yes, that is exactly right.

The drawings look good.
Bill of materials with websites is nice.
The bearing bores need to have their own

I feel bad pointing out things like this to someone.
