Thats not showing base thread, and 26 u-s of servo-thread jitter?  Dunno.

All in all, it sure looks like a good build.

Thank you for the information.
But I have some basic machines that work with linuxcnc.
No problems.
Today my machining center out of use I have in process an order.
With linuxcnc I am independent

Hello,

We have a machining center Cincinnati Milacron Arrow 750.
The control of the machine is out of service and we will change it.

I am searching information on the spindle motor and drive:

High performance induction motor
Model: 1-604-0006

Kollmorgen Ind or Cincinnati

SPINDLE DRIVE 30AMP VFS5

Kollmorgen Ind or Cincinnati

Can you give me the technical documentation?
*I am searching primarily voltage frequency curve**?*

Best regards,

Pierre

If you have the SX 850 control on your mill I am not sure I would give up on

[Emc-users] Need some math help

[Gene Heskett]

Greetings all;

That code snippet I posted to the devel list, could use some help.

These parts are nominally 2.05" wide, and I normally locate them in the 
vise so they are resting against a small bit of wood held across the end 
of the jaw opening as I clamp them up in the vise.

However, judging where to touchoff X, or play with Y to get the cut 
centered on the wood, which will vary as wood will, is being a problem.

If I could somehow determine the Y offset that would put the tip of the 
cutter at a fixed point, I could then drive the machine to put the 
corner of the edge of the wood at that fixed point about 10 thou from 
touching the near corner as I turn the cutter past it by hand, would be 
a tremendous amount of help. 

Then I could put in if needed, some fixed offsets to make sure it doesn't 
overcut and wreck another part. I only have 3 spare parts left to 
experiment with right now before I have to make more, and they are 
slightly thicker raw material than a S4S 1by, so I have to cut up sticks 
of mahogany that were going to be Gibson Guitar necks but failed 
inspection.  I do have 3 or 4 more of those, but the supply isn't 
exactly endless.

The final size of the arc is as yet unk, but is designed in my head to 
make up for the fact that my home made cutter for this is about 1/2" too 
small to cut the arc directly, it would be too deep in the center, so 
the arc is to effectively expand the cutters diameter by however much is 
correct. For sure, the .73" set in that code when I posted it is too 
much as I am still overcutting the edge of the workpiece. I found after 
making the first tooth that I had to make it about 1/4" longer for heel 
clearance, and because of the cutter attack angles, the wings of the 
cutter had to be opened up at an included angle of about 110 degrees in 
order for it to be 90 dgrees as it swings.

In my mind (whats left of it), the ideal would be to drive x straight 
with y=0  until it touches in the center, subject only to the 2 thou per 
pass x increment, and let that be a fixed point by calculating the x 
retraction as the arc is done and adjusting the r value to "flatten the 
wings of the arc" by enough to cut the exact same arc as exists, with 
that center point remaining motionless.  As it exists now, the g3 
determines the amount of center projection.  It shouldn't have to move 
much in order to put the tooth as close to the corner as it can be/is, 
sufficient to touch the corner is all I need, and even at less than the 
width of the part, the motions are obviously excessive, cutting huge 
amouns of air on both sides of the part.

A outline of a procedure to do that would be a learning experience to 
implement. So would a method to automatically adjust the length of the 
arcs chord to get rid of the air cut as its wasted time.  I'd assume 
that this is interlocked, but which to calculate first? IDK.

Many thanks for any hints. 

Cheers, Gene Heskett

[Emc-users] One learns things by reading the docs

[Gene Heskett]

Greetings all;

Skimming thru the doc pdf, under functions on page 204, I see there is an 
EXISTS[#] function that I propose to make use of.

The one big file that carves the ends of all 4 major board parts of the 
blanket chest, uses just 2 variables at the top of the file to control 
which of the 4 boards it is carving during this invocation.

This means a goodly number of trips into the editor in order to set them.

Experimentally I have found that these variables seem to be able to 
survive in memory unless a full powerdown reboot has been done. That 
surprised me when I found that several years ago and it appears to be 
true yet today.

So, what I am considering doing is writing 4 individual 8 or 10 line .ngc 
scripts that set these values into the 2 named variables so that I can 
then remove the creation of these vars from the main file and use only 
what the 10 liners have left behind, thereby removing the need to edit 
any of those 5 files to run it in whatever configuration one of the 4 
new files sets it to.  The exists[] would be used to trigger an 
unconfigured message to the big dummy that I can't run it after a 
powerdown without first running one of the 4 config .ngc files.

Is this practical, or am I playing with fire?

Thanks all;

Cheers, Gene Heskett

Re: [Emc-users] debian locks on boot

[bari]

Your APU and chipset should work just fine with Debian and they already 
have.

I'd try a fresh install and see if it works again. Then maybe run 
memtest for a few hours. It could be flaky hardware but I'd reformat and 
reinstall to rule out software being the problem first. Pay attention to 
any updates or changes to drivers after you install to see if they have 
issues.

that's interesting, I have an AMD E350 that I just installed 32 bit
Ubuntu 14.04 on and it runs fine so far. My experience with these
kinds of locks is that it's the graphics driver.  I had an earlier AMD
processor that would lock up randomly under Ubuntu 10, but 12 fixed
that.  I never got around to troubleshooting it after the upgrade
worked. I think you can debug over a serial cable, but I never thought
it was worth it.

OK, Here is some more information on the computer. I thought "Dads 
Laptop" was sufficient! LOL!

I don't need the real time kernel. I thought for my own sanity that I 
had better install the same thing that I am using here. I was going to 
update and pull a standard kernel during the update.

The weird thing about this is that it would boot fine two nights ago. I 
powered it down when I finished with it Monday night and now it won't 
finish booting unless in recovery mode.

I installed several applications using apt-get. Icedove, gedit, 
GpicView, GnuCash, AisleRiot Solitare, Wine. I was trying to use wine 
but in the end I did not need it.

Anyway about the computer
