Re: [Emc-users] Something went wrong.

[jrmitchellj]

First, if you have a lot of backlash in the X & Y movements, you should
avoid climb milling.  When the cutter grabs the work, it will take up the
backlash (and maybe break the cutter)
As for the way you have the work in the vice, I would ditch the round
stock, and clamp it lower in the vice.  I think you have a lot of flex in
the setup pictured!  Keep the horizontal part of the part within about
1/8th of an inch of the top of the vice jaws.  If you really want to
use the round, flip the part around (the z axis), put the round stock so
that it clamps the stock very close to the top of the vice jaws.  That will
minimize the flex.

Re: [Emc-users] electrical inspection pain

[jrmitchellj]

In Los Angeles City, County, and in Burbank (where I work),  it has been
the rule that everything used in a facility must carry the UL tag or a
testing certificate from an accredited testing facility.
It has been this way for a few decades now!
that is when lots of companies started to use UL approved wall warts for
all of their products.

Spiral flute taps for blind holes.
Spiral point taps for through holes.
For aluminum, I use uncoated, or bright HSS taps.

I have been doing alot of m2 & 4-40 holes with rigid mounted taps, none
broken!  All blind holes.
The difficult part is figuring out how far the spindle overshoots
(rotation) for reversal.  On my milling machine, I have it down to half of
a rotation overshoot, using the braling on my Yaskawa VFD.

Got home & checked the debian-version file, which states 7.11.  As I recall
that is Wheezy.
That is only 5 years old.

Re: [Emc-users] back to a bad cable?

[jrmitchellj]

I don't run ribbon cable any longer the 12inches, and keep it against metal
surfaces to minimize noise induction into the cable.
There are ribbon cables that have the pairs twisted for a length, but you
are limited to connectors every foot.

I use shielded twisted paired cable for anything longer.  More work to
terminate, but much more reliable!
I use a lot of Belden 9451, and 8723.

Re: [Emc-users] anti-freeze recommendation for water cooled spindle motors

[jrmitchellj]

I concur on not getting bleach anywhere near stainless steel.  I am a
HomeBrewer and have lots of Stainless vessels, and I won't let Clorox
anywhere near them!.
I have seen algae or other slimy growths on filter cartridges that seems to
attack and swell the urethanes or silicones used to assemble the pleated
cartridges.
So if the motor has any of those in its construction, that may be the cause
of the slowdown.

Re: [Emc-users] anti-freeze recommendation for water cooled spindle motors

[jrmitchellj]

Sounds like you have a bad algae growing in the system.   I have seen some
algae go for the plastic/poly, and eventually break it down.
It may take a medium to strong caustic (Draino) solution to break it down.
But that might not be very good for the internals of the motor.
Without knowing what materials are used inside the motor, caustic might be
risky!
Have you considered putting a UV light over the tank to try to keep the
coolant sterile?

Re: [Emc-users] buster xfce4-goodies installed, ought to have a power capable screen blanker.

[jrmitchellj]

Gene, if your remote shell sessions are being dropped, more than the
display is going to sleep.
When I run remote shell sessions that I need to keep alive, I use either
screen or tmux.  Once you shell into the remote machine, start screen or
tmux, then you can start your process in that.  If the link goes down, the
screen (or tmux) continues running.  You would just re-establish the
remote link, then re-attach to the screen (or tmux) session.  You can have
multiple screen sessions open.

Re: [Emc-users] Linux CAM.

[jrmitchellj]

I have recently been using rest machining to speed up some parts.
One part I was working on, the first article came off at just over 5 hours
run time.  It had a lot of corers with 0.03" radius, so very small cutters
were needed.
Moving to larger cutters in the beginning for bulk material removal, then
using progressively smaller cutters with "rest" to get the details done.
I had to create some additional sketches to constrain the "rest" paths to
certain areas of the part.  Otherwise the path chosen by the Fusion tool
would spend time cutting air.
The part also had a bunch of drilled & tapped M2 holes.  The LinuxCNC rigid
tapping cycle worked wonderfully!

I was in fear that when Autodesk picked up HSMWorks, shat they would not
keep the Solidworks plugin available, but am glad they did.  The high
school Robotics team I still work with is still using Solidworks.

Re: [Emc-users] cnc axis "Touch Off"

[jrmitchellj]

On a Mill setup, touch-off only affects the Z axis.  You will need to find
your X0, and Y0 positions.  I use the end key to bring up the dialog and
set the offset.

Re: [Emc-users] Work coordinate offsets produced by Fusion360

[jrmitchellj]

Thank you Gene!  I will look into it.

Fusion is really good at allowing you to set up multiple fixtures to run
parts in to minimize tool changes.
I have made fixture plates to machine the end plates on a couple of the
Hammond extruded enclosures.  Five positions, four screws to hold down the
plates.  You just need to set up the coordinates for each position on the
fixture plate.  That was easy!  These blocks have details on each surface,
so many more setups needed.  For this job, it is five pieces X 35, so I
thought I needed some speed-ups.

Re: [Emc-users] Work coordinate offsets produced by Fusion360

[jrmitchellj]

Now that change is very easy to understand!

I was trying to report this to a person I was incontact with @ HSMWorks,
who (I think) released the first LinuxCNC post for HSMWorks, but that was
around the time that Autodesk acquired them.  They do not seem to be there
now. (or their email address has changed)

Swapping .var files seems the easiest way to go, and I will looking what
Gene is suggesting.
Just curious, can the .var file be specified on a command line when
starting LCNC?

Thank you all for the help!

Re: [Emc-users] Work coordinate offsets produced by Fusion360

[jrmitchellj]

Yeah, I am sure it is in the post processor.  I pulled it down and had a
look at it, but I am not a programmer. I found where itis stated, but have
no clue how to change it.

I am running out of workspaces.   I am doing a 2-up run with a blank in
each end of the vice, using workspace rotation.  Pushing my envelope!
I am thinking that once I have a couple of parts lined up & touched off, I
could save the .var file to a nema relevant to the parts, then when I need
to make some more of those, move that file back to linuxcnc.var, start up
the system, and be ready to go with the setups.  save an hour right there.
But 2 parts, six sides with features to be machined, means 12 offsets.
LinuxCNC has 9.

[Emc-users] Work coordinate offsets produced by Fusion360

[jrmitchellj]

I am producing several parts for an associate, and wanted to use several
offsets for the various sides of the part.'
All was going well until I got to G59.1 (offset 7 in F360).  It formats the
command as "g59.1 P1", and LCNC does not seem to like it.
I edited the problem entries in the NC file, and the machine accepted the
corrections.

Has anyone come across this issue?

Re: [Emc-users] Problem with Rigid Tapping on USC Equipped Bridgeport

I went through the technical manual, and found the variables to tweek to
enable the resistor braking.
On the Yasawa they seem to  be:
L30-04 = 3
L8-01 = 1
then I set:
C1-02 for .2  (sec) deceleration

Oh boy, what a difference the correct settings make!

It's expensive, but you can find it on special a couple times a year.
I work mostly with aluminum, and their system works very well.
I keep the mist flow low to stop puddling (and put absorbent cloths/sponges
around the vice).

The importance of coolant (in order of importance):
1  clear chips from cutting area
2  lubrication of the cutter
3  cooling

I use a 16oz PET bottle for the reservoir, with a super magnet from a
failed disk drive attached to it.  I put it on the side of the knee mill,
and move it vertically to get the best mix of air vs mist.
It sits about 10" below the work when running, and i'll move it up to the
cutter level to get the mist started.

I do not leave the reservoir on the machine between sessions, as gunk seems
to want to grow in the lines.  I cap the bottle & put it in the shop fridge.

After reading Gene's adventures with the eBay misters, I felt my time is
too valuable to spend on messing with something of questionable utility.

I hope this helps!

Re: [Emc-users] Problem with Rigid Tapping on USC Equipped Bridgeport

[jrmitchellj]

Hi Scott.
I have a Yaskawa V1000 on my spindle, and have installed a encoder on the
spindle.
Would you share what settings in the V1000 to get rigid tapping working
well?  I have braking resistors installed, but don't know what variable to
change to bring them into play.

Any help & tips always welcome!

[Emc-users] setting tool length offsets

[jrmitchellj]

Has something changed in Master with the process of setting tool length
offsets?

I am not seeing the "Tool Table" option in the touch off dialog.
Or am I just doing something out of order?

load first tool with t1 m6 g43, og to reference point, set g54 to zero
load next tool with  t2 m6 g43, move to reference point, open touch off
dialog, no tool table option.

What am I doing wrong?

Re: [Emc-users] Leaving an axis out of the home sequence AND (continued:)

[jrmitchellj]

Maybe I am thinking too simplistically, but my approach would be:
Start with my 3-axis config
Copy it
add the fourth axis information to the copy
change the name of he config to 4 axis.

The steppers I used cannot have the motor connected while powered.  So this
method suits me.

Re: [Emc-users] Home-limit switch measuring

[jrmitchellj]

As I tell the robotics students, design limit switches to survive missed
detection & over travel.
On a milling machine, I would recommend a roller type of switch, that would
come in contact with a cam bar that is long enough  to reach end of travel.

On my machine, I have two switches positioned about an inch apart, at the
middle of travel.  Then the are cam blocks, one positioned near each end of
travel
The roller rides up on the block, trips the switch, and the switch body is
safely out of the travel path.  I did my mill this way because I have sooo
many pins available with the Mesa kit.

On the school mill, I used one switch for each axis, and the cam block from
either end of travel would trip it.

So no failure (or other malfunction) will crush a switch!

Re: [Emc-users] Nuther air problem.

[jrmitchellj]

If you are using it for a mister, you should not hear the release of a puff
of air.

You have the option of putting plugs in the 1/8" ports.

I use a valve like these for a cylinder for my spindle brake, and it does
need to release the air when changing state, or it wouldn't move.

Re: [Emc-users] Nuther air problem.

[jrmitchellj]

Exhaust from the closing side.
In one position, the center 1/4" port is open to one side 1/4" port.  The
other side 1/4" port is open to the closest 1/8" port.
activate the solenoid reverses the logic.

At lease that is how the ones I have work.

Re: [Emc-users] head scratcher, updated some more

[jrmitchellj]

On the Yaskawa VFD I am using, there are registers that can be changed to
alter the function of the run & fwd/rev inputs, so the names really are
silly.
There are a large number of those registers that change a bunch of things.
It took me several days for me to find the ones I needed to tweek.

Hey Gene, If you were so inclined to make your own touch probe, there is an

Re: [Emc-users] New problem, how best to solve?

[jrmitchellj]

I had a similar issue with a Shapeoko router.
There was no continuity from the spindle rotor to the rest of the assembly.
My solution was to mount a brush above the spindle motor shaft, to make
contact on the end of the shaft, then bring that back to the sense input.
And, yes, I brought a ground wire out to the workpiece to be sure the
circuit would be complete.

Re: [Emc-users] Would this blower be usefull as a low pressure mister for this 6040

[jrmitchellj]

Most of the pneumatic valves I use have a small actuator (coil) that opens
a small air passage to push the thimble within the valve body to the
requested position.
I recall that they are called "pilot valves".
So they use a very small amount of current to do a very big job.

I have used Parker pilot valves in the past, but they have gotten way too
expensive, so I am trying some from China.
I found (on ebay) Toolots, that carry products from Pneulead.  I hope to
get them installed on my mill this weekend.

I am using 3/8" units, as I needed that for my power drawbar.

With that thin of a chip it is doing more "rubbing" than "cutting", and
with a lot of heat in the chip, it is likely going to start friction
welding the chips to the cutter.
Things can go downhill very fast, and a broken cutter will result!

With the cooling rig that I have, the part often comes off the mill cooler
than when it went on.  I keep the mist quantity very low, so the air moving
it evaporates it quickly.

Re: [Emc-users] Would this blower be usefull as a low pressure mister for this 6040

[jrmitchellj]

The flow rate of the coolant is adjusted by rotating the nozzle at the end
of the flex line.
You can even adjust to cut off the coolant flow completely, and just have
air flow on the work.

Re: [Emc-users] Would this blower be usefull as a low pressure mister for this 6040

[jrmitchellj]

Yes, and Yes.
The units Andy sited  on EBay look like a similar design to what I have.

The key is to keep the bottle a bit lower than the exit plane of the nozzle,
so that when the air is shut off, the coolant drains back, not continuing
to syphon (dribble) out the nozzle.

Re: [Emc-users] Would this blower be usefull as a low pressure mister for this 6040

[jrmitchellj]

I just use a 16oz water bottle with a magnet attached.  Drop the pickup
tube into it, and the coolant is drawn out.

I mix up the coolant in small amounts, as it seems to grow a slime in it if
it is around too long.

Re: [Emc-users] Fusion360 gcode= "Radius to end arc differs from radius start"

[jrmitchellj]

I ran into this problem after i botched up a touch-off, and an entry got
into the tool table that should not have been there.
The way to check is to open the tool table in the tool table editor, in the
mode that shows all columns.  If you have offset entries in any column
other than the Z axis, clear them, save & try again.

Re: [Emc-users] OT: X-Y query

[jrmitchellj]

I always reference the fixed jaw.  As good as the vices are, the moving jaw
can twist slightly if the work you are clamping is not square.

As far as which corner of the jaw you reference to, do what you are most
comfortable with, the machine will obey the command set you send it

On some parts I have made, I mark the stock corner to corner to find the
center.  That way I am extracting the finished part out of the center of
the raw stock.
Since i have been doing that I have changed my work holding strategy away
from mostly vice, to tooling plate and edge clamps. I will drill & tap
holes that match the holes in the part.  drill the holes in the part first,
then screw the part to the tooling plate.  Remove the edge clamps, and
finish the part, edges and all.

Re: [Emc-users] dsub-25-cutout.ngc

[jrmitchellj]

yeah, It was a bit of a pain to set up.  It's been a very long time since I
have used it.
I think that someone built a more capable version of ngcgui, but I have not
tried it.  There was a pretty big thread in the forum about it.  I think it
is called nativecam.

Yeah,  I thought my keyboard had picked up some chips, except other stuff
in the linux environment responded to those keys correctly.

The quick reference  sheet under the help menu shows all the shortcut keys.

I have not checked out all of the shortcut keys, so there my be others that
are not working correctly.

Joint 2 error on a 2 axis machine, hmm.
Would it only have joint 0 & 1?
Is it possible you opened a 3 axis config?

JUs for some background:
how is the motor connected to the spindle?  Is it V-belts, cog belts, or

V-belts would cause me to think twice due to possible slippage introducing

Re: [Emc-users] Odd encoder problem

[jrmitchellj .]

The best contact cleaner I have ever used is De-Ox-It from Caig Labs. (the
red stuff)
I have restored millions in broadcast and television equipment to proper
service with it.

It is amazing how much grub it get off connectors, without harming the
plating at all.

Re: [Emc-users] One final Q re using a dc spindle motor

[jrmitchellj .]

I am working on a Jet JTM-2 (Bridgeport clone from Taiwan).
Re-fitted with a 3hp 3ph spindle motor, and axis kits for motorizing X, Y,
& Z from Elrod Machine Works in Arizona.
Originally was going to build them myself, but thought about the hours
required, and felt the Elrod kits were well engineered, and worth the price!

I do have a few widgets in a pyvcp, but 2/3rds of the space is still open,
so I would be interested in what you have done.

I would thin a 1HP drive should be able to plow through and thread a 3.8"
 hole without much grief, especially in low gear.

I have not set up my system for low range yet.  Allot to think about on
that.  Still working on the basic system & bugs.

I was just thrilled to get the speed indicator and "at speed" signals
working correctly!

Modern TVs are essentially "unserviceable".  New sets can be built faster
than any repair would take.
Fortunately modern sets are vastly more reliable than their predecessors.
Now manufacturers have to come up with gimmicks to sell new sets.
 currently, that is 4K!

I would get to a very basic setup then add a feature or two at a time,
test, rinse, repeat, until it breaks, then back up one step.
Disable things like backlash & leadscrew correction, as I think they could
have an effect on counting.

Some of the signals in your HAL example are quite different than what i
have in my config.  Did things change a lot in 2.8?
I don't have anything with "joint" in the name.  Do have a bunch with
"axis" in the name.

Re: [Emc-users] PC MB for Linux.

[jrmitchellj .]

I have noticed the minimum size for Axis when tuning my system, trying to
make room for HALSCOPE and the calibration window.
I believe the window manager is doing the actual re-sizing, not Axis
itself. (I could be wrong on this)
I first started looking into this, after using pncconf, and selecting to
maximize Axis.  Then opening LCNC and finding it filled the screen, plus
being off the bottom by about 30 lines.  Couldn't have that, important
status down there!

Re: [Emc-users] PC MB for Linux.

[jrmitchellj .]

I first ran into this problem when I started building a new system with the
latest live iso, based on Debian.  It worked as expected on Ubuntu 10.04.

There seems to be multiple issues happening.
>From what you describe, it seems that the system is expecting a wide (16x9)
display.  There may be a setting in the display widget for this. If not ,
you may need to dig into the xorg.conf file.  I set up my machine on a 16x9
monitor, then moved it to the shop that has a low resolution 4x3 monitor,
so I had to change that setup.
Next,check to see if the monitor has an "auto align" or similar in it's
menus.  If so, run it.  It will adjust the monitor to what the computer is
sending it.  Magic!

The next issue I ran into was Axis display much taller than the display.
For that I had to edit the hidden .axisrc file in the home directory.
Finding information on that was difficult.
In that file, there will be a line like:
1 root_window.tk.call("wm","geometry",".","1270x970+5+0")
That sets the size & location of the Axis window on startup.  That example
is what I have set for my liking.  The four numbers are: height, width,
from left, from top.  My display is a 4x3, 1280 x1024.
So I made the Axis display a bit smaller than the display area of the
monitor.
In adjusting this, I found that about 100 lines are off the bottom of my
display.  I haven't had time to chase that down yet, I just tweeted the
.axisrc file to get it to fit.

A bit log winded, so I hope this is the information you were looking for!

[Emc-users] list subscription expired?

[jrmitchellj .]

I realized that I have not gotten any posts from the LCNC list since Aug. 2
Upon invesigation, it looks like my subscription went away.  So I signed up
again.


Now for a question:

Is there a facility in pncconf to export the settings to a delimited file?

I am looking for an easy way to generate documentation.

W. W. Grainger might be your friend for parts to repair the S. Z.
I have repaired bottle chests (like used in a bar) with parts from them.
Home brewing is annother of my passions.

Re: [Emc-users] Way OT, Unexpected Result from Refrigerator

Likely the heat generated by the running compressor is what is heating the
cabinet.
Without refrigerant, no way to move the heat to the condenser.

Re: [Emc-users] 3D Printers

[jrmitchellj .]

Kind of small.
ACME leadscrews instead of ballscrews
Not much detail on the build platform (other than thickness)

Probably OK for  a learning experience & making small toys.

Re: [Emc-users] OT: Servo drive tripping out

[jrmitchellj .]

If you follow Gene's suggestion, while you are in the unit, check the
circuit boards for cracked/stressed solder joints.  Over the years, heat
cycling will cause joints to crack, especially in areas that generate heat,
like around resistors & transistors.  Capacitors can also heat up causing
cracks.  As they age, their ESR can rise, causing more heat buildup.

I have repaired countless items by nothing more than reflowing solder
joints!

If you are allowing your equipment cabinet to rise to 95 before cooling
starts, the localized rise will be much higher.
