I'm printing an 8mm hole with an expanded dflat in the center of the 
elliptical armature for my version of the harmonic drive. The hole is 
spec'd at around 8.35 mm in diameter and a square about 8mm wide is 
positioned inside the hole and makes the dflat. Its is a tight friction 
fit, after the dflat has been ground about 1mm deeper, so a caliper ob 
the flat, measuring about 6.5mm to the back of the rounded shaft. Fits 
repeatedly with a friction fit, no backlash but with a teeny amount of 
eccentricity that shows up as a slight error in the output angle when 
running, which translates to a speed warble is it turns an A axis from my 
6040 mills 4th axis on my kitchen counter, So the overall accuracy is 
probably 30 arc-minutes. The motor is a 1NM 3 phase stepper, with a big 
printed 60 tooth gt2-3 pulley replacing the sloppy key fit OEM pulley on 
the chuck shaft, and the output pulley of a 50/1 loose belt harmonic 
drive is 53 teeth resulting in a belt that tensions about right without a 
tensioner.

It been running, both directions, for about a month now, no failures. I 
can't stop it by hand so I think I can carve tracks in a piece of steel 
in that 3" chuck, with an 1/8" mist cooled SC mill turning 20k revs.. 
carving square threads for instance, I have visions of making the 1"x 18" 
bolts for a woodworking vise with it.  Or maybe even in a hard maple 
wooden dowel of even larger diameter. 

I'm cheap, the drive is 100% printed in PETG, and the only metal in it is 
the 5 printed bearings, 4 on the armatures ellipse, to drive the loose 
belt and the huge, single row, output disk bearing nearly 90mm in 
diameter, the balls are crosman bb's inserted into the printed races. I 
don't think I have more than 10 dollars in it not including my time baby 
sitting the printer.

If it breaks, print another one, No metal in that hub. I have an idea 
that might smooth up the motion, based on the dflat pushing the armature 
a thou or so off center, interchange the signs that make the ellipse to 
put that potential wobble not in line with the engaged splines, but 
inline with the slack disengaged splines, effectively turning the dflat 
90 degrees. But that has not been tried yet, I'm life testing what I 
have. The previous, smaller, 30/1 version ran 4 months, no failures.

The Fenner method looks interesting but $50 for an 8 or 10mm bore? So I 
made taperlock hubs smaller than anything Browning sells for all that 
stuff when I put those mini ball screws into The Little Monster. When I 
found the lower dual pulley in the Sheldon all wallered out cuz somebody 
back in the fog of time had installed it bass ackwards and left out the 
key so it slipped and tore up the shaft trying to tighten the grub screw 
enough to stop the slippage, I took it to TLM and rebored it for a 
homemade taperlock. flex slots for all that cut with EDM. zero burrs to 
clean up. Hell to do the jack screws inside that yoke, very little room 
for the allen wrenches cut way down short arm, but it works, probably 
better than the OEM setup.

Take care & stay well everybody.

Cheers, Gene Heskett.

Take a grinder to the motor shaft and make a flat on it.  Then tighten the 
setscrew on the flat with some Loctite on the threads or a second setscrew 
behind it if you have the room.

The RTAPI is a wrapper that supplies a uniform interface (API) for all
supported Realtime (RT) systems.

So the same RTAPI functions work for RTAI (kernel and uspace[1]),
Preempt-RT (uspace)  and Xenomai.

[1] Yes, you can compile uspace with an RTAI kernel, but I can think
of few reasons to do so

Wel, they _should_ show up here at the bottom under "Hostmot2 API Calls"
https://linuxcnc.org/docs/2.8/html/
But they don't. Oddly.
They do appear in the old docs.
https://linuxcnc.org/docs/2.7/html/

It looks like the man pages are not being built. I hadn't noticed.

Not entirely legible versions (ie, groff/troff source) appear here:

[Emc-users] BSPI man pages reference in documentation for mesa and hostmot2

[John Figie]

In the documentation for BSPI at
http://linuxcnc.org/docs/2.8/html/man/man9/hostmot2.9.html#BSPI there is a
reference to some man pages like man mesa_7i65, which prints the man page
when I issue the command for it,
But the documentation also refers to some other man pages for the the
following: man hm2_bspi_setup_chan, man hm2_bspi_write_chan, man
hm2_tram_add_bspi_frame, man hm2_allocate_bspi_tram, man
hm2_bspi_set_read_funtion and man hm2_bspi_set_write_function for the
exported functions.

I see that these functions are called in the Mesa 7i65 component that Andy
Pugh sent me a while back
https://github.com/LinuxCNC/linuxcnc/blob/master/src/hal/drivers/mesa_7i65.comp

My questions follow:

*1) what must I do to see these bspi man pages?*
*2) what does "exported function" mean in the context above?*
*3) in the 7i65 component there are some lines that refer to RTAPI but in
my case I am planning on using the PREEMPT RT enabled kernel. Does the
component work with either?*

My goal is to create a sub driver component to send and receive data via
one or 2 of the SPI channels that are available for one of the FPGA bit
files such as 7i80hd_25_svsp8_6_7i46.bit

I have asked about this in the past, but now I am really  ready to make
things work. I have hardware in hand.

John Figie

thank you but this procedure did not work.
I am saving my directories and reinstalling the machine from scratch, I
would need an ISO for master branch, how do I get it if it is
available?

Re: [Emc-users] 60's vintage position feedback.. (GE Accupins)

[Scott Harwell via Emc-users]

 
Inductosyn has a major cost advantage over Accupins. It is a copper film bonded 
to a steel backplate. It is a photo etch process like a circuit board. 
The slider is the same process with a thin foil protection over it. The slider 
provides sine and cosine, and the scale reads displacement. They use a varnish 
to protect the copper left after the etching.

 Very cool Sam. It looks like the pin rail may be reproducible, but do 
you have any idea what the coil pickup structure is? Probably 3 coils... 
excitation, and the 2 quadrature phase or possibly many coils on a 1." 
spacing. The concept is very interesting if we could reproduce sensors 
like this at a reasonable cost. A similar product was call inductosyn I 
believe.

I have seen a similar sensor that used ball bearings in a tube. 
http://www.newall.com/technology/   this seems to show a good cutaway view.

One idea I had was to try and use a ground ball screw as the sensor rail 
with magnetic pickups on several of the threads. Thus the rod providing 
the positioning would also provide position feedback of the nut (sensor 
coils ride on the nut). A slightly different idea (and probably less 
precise) is to use a rack as the sensor.

With optical encoders being so cheap these days, its probably just an 
academic interest, but any ideas you have on the pickup coil design 
would be very interesting.

Re: [Emc-users] Qtpyvcp error

[Rene Hopf via Emc-users]

Did you recently pull master?
You are using python 2.7 which isn’t supported in master anymore.
The updating documentation has steps required to change the configuration for 
python related things.
