My understanding of motor cogging is that it is the torque or speed 
variation due to the layout of the magnetic poles.
https://en.wikipedia.org/wiki/Cogging_torque

This has been an issue with DC brushed motors when driven by a simple 
voltage source. Generally, half the rotor coils are energized South and 
half North. As the rotor turns the brushes change the polarity of a coil 
in order to shift the magnetic phase of the rotor away from the stator 
in order to create torque. This is a one coil quantum change, so the 
torque is also a step change, therefore not smooth. One way to smooth 
the torque is to twist the rotor coil layout the adjust the torque 
profile relative to the rotor/stator position.

This still is in the context of driving a motor with a simple power 
source. When speed, position or other feedback is added to control the 
source, cogging does not apply.

Cogging could be an issue for AC or DC brushless and AC induction motors 
if they are driven by a simple power source that matches the type of 
motor -- AC induction needing AC mains power with properly phased legs, 
AC brushless needing three phase AC sinusoidal power, and DC brushless 
needing three phase trapezoidal power.

Very nice! I like the Joinery. What are you using for the square pins in 
the joint? I like some good woodworking.

My next big woodworking project is new office furniture. It will 
probably take me and my dad about a year to finish the project I want to 
do. Executive desk, full 12' wall of bookcases. printer cabinet and 
whatever else I can dream up. Right now I am working off a white plastic 
folding table, LOL.

Keep up the good work.

[Emc-users] Program prefix

[Eric H. Johnson]

HI all,

Has there been a change to PROGRAM_PREFIX in version 2.6 or later, currently 
using 2.7.

Under 2.5, if I issue the 'open' command from linuxcncrsh it would pull the 
file from the path specified by PROGRAM_PREFIX in the DISPLAY section.

Now it seems whatever I put in for that parameter, it pulls from the associated 
configuration folder.

I have also tried including and removing the final '/', and specifying the 
absolute and relative paths.

This is working fine on version 2.5, although the path is slightly different 
with emc2/nc_files instead of linuxcnc/nc_files.

Thanks,
Eric

I did, but the server is holding it for the moderator to clear as its not 
quite 20k over the 360k size limit allowed.  I smunched it down to a 20% 
quality jpg, because I could see jpg'ing artifacts if I went any lower.

I'll try doing some cropping of some of the background in gimp.  Or is 
there now a more compact image compression format?  Cropping an image in 
gimp is the most frustrating thing I have ever tried, I have to ask for 
help on the gimp-users list every time, so it still has white borders. 
Damit, a crop should remove what you don't want, not fill it with white.

Anyway, new version 2 attached, smunched enough that jpg is showing some 
artifacts.



Cheers, Gene Heskett

[Emc-users] Problem Connecting LCNC to G540 from PCIE Port

[Willy Snow]

Hi All,

First, I am pretty new to all of everything. I am hoping someone can point
me back in the right direction.

I am trying to get my bench setup running. I have a single nema 17 motor
connected to a Gecko G540 using a 24V PS. I can power up the G540 with the
charge pump off and the motor holds and the light is green. This seems to
be a success.

I cannot get LCNC to talk to the G540. Using Stepconf Wizard, I trying
setting Parport Base Address to 0, 1, 0x378, 0x278, 0x3BC, 0x378 in 0xd010
in, 0x378 in 0xd000 in. None seem to work. I suspect the PCIE card is not
communicating correctly. Pin 16 is always set to charge pump.

The card is a SD-PEX1005. I bought it since someone in the newegg reviews
said it works with LCNC. I trying following the linux driver install
directions, but quickly became lost. The directories do not match up??

You could try "cat /proc/ioports" though I suspect it will give the
same answer as you already have.

Does the linuxCNC parport driver load?

Does lsmod show "lp" ? That might suggest that something has grabbed your port.

Gabon ebony fitted plugs, I have a routine that drills the hole thru the 
finger for an assembly screw, a 2" long SS for century plus longevity, 
with a round pocket for the screw head, and a square pocket above that 
about 3/32" deep with the 1/16 radius corners a 1/8" mill leaves when 
driven in a square pattern.  And I make the ebony plugs, including the 
rounded tops, in another jig after they've been cut out of a thin sheet 
of ebony by another routine.  The plugs get their sides tapered a few 
degrees against a disk sander, a coat of Elmers finest on the bottoms 
and driven into the recess with a soft faced dead blow hammer.

The longer bits of ebony in the lid with its breadboard ends is actually 
more trouble than these are.  Breadboard ends aligned with white ash 
bits & pieces in deep grooves routed in both pieces. The only place its 
truly glued & screwed solidly is at the center where in this case, since 
the top has an edge joint there, a screw into each board on both sides 
of the joint.  All the other offcenter is longer because its covering a 
slot the screw cam move in with the seasonal changes in humidity.   The 
long bit in the corners are only glued into the slots in lid board, and 
can move freely in the breadboard ends as the seasons come and go.  The 
boards will grown and shrink in width, but generally not length.

All the edge joints are full of bisquits, should stay together for a few 
decades (I hope) But the stock I have laying on the floor now is 1x12, 
so the only edge joint in the next 3 I make will be at the lengthwise 
centerline of the lid.  I could only locate 1x6's for the raw material 
the first one you see was made from. Changed vendors, now have 1x12 
stock.

But that wider stock has me looking at a new saw to replace my 12" Dewalt 
miter/chopper.  Bosche is out with a whole new design that does away 
with the sideways slop on the usual sliders. I played with the displayed 
one at Home Depot 2 weeks ago, and that suspension system is easily 10x 
more rigid against any side forces applied than any other slider on the 
shelf.  And my 12" chopper can't cut a full 12" width.  Its also about 
$200 more than I paid for the Dewalt miter/chopper 6 or 7 years ago.  
The card has enough surplus it won't be noticed except by the missus 
when I unload it. :(

Those hinges are Rocklers, very high friction, used so that little 
fingers clamboring for a grip to stand up, will not be smashed by a 
falling lid.  It takes about a 20 lb lift to raise the lid to where you 
see it in the pix. Nothing else is holding it up.

Pricy too.  The strip under them at the rear is screwed, glued and pegged 
into the board below it about every 3 or 4 inches as that strip in 
addition to holding the torque of the hinges, also projects inward and 
has a 1/4" wide groove in the bottom to retain the cedar lining.  Theres 
a groove routed in the base panel to hold the end of the cedar "planks", 
closet liner from Lowes.  That groove, with the cedar in it, was 
actually used to align the box when I set it on the base, forcing 
everything to be as square as the mahogany faced bottom plywood panel 
is.

If I think about it in time, and I have enough ebony buttons left, (a 
2x2x12" piece of that was a hair shy of $70 dropped on my front deck) I 
may use them in the front strip to hide the well countersunk screws.  
The front and end retainer strips are not glued, a paen to making some 
of the cedar removable for a light sanding to remove the resin it exudes 
which seals it up and the cedar odor goes away. A light sanding to 
remove that resin restores the cedar odor for a few years. Its just part 
of cedar maintenance.  If your house has cedar lined closets, that needs 
to be done to them on about the same schedule.  IOW If you can't smell 
it, sand it. About 150 grit, sand gently, just hard enough to make some 
resin
