Re: [Emc-users] Wax

Ive seen shops using plaster of paris to do exactly what your wanting.  
its a bit more stable then
wax can be, and it may end up being less expensive. As far as removal, I 
think the stuff will pretty much crumble, you could even mold in some 
holding method, who knows, just tossing it out there. good luck.
pardon in advance if I posted to the wrong section of this topic.

Re: [Emc-users] E-stop Suprise

[Greg Michalski]

I wasn't trying to imply that the escape key should be someone's trusted way 
out, or that it's ok the button on screen didn't work.  I was actually implying 
that it was still a bad habit of mine, as would be the button on the interface. 
 I'm training myself to hit the estop(s) (meaing the physical ones) but old 
habits die hard - I'm still working on it.

I agree the one one screen should always work, but the computer controller 
going bonkers is always a possibility therefore we should all - regardless of 
machine size or experience - have physical estops and train ourselves, and in 
the case of shops - the operators - to rely on them and not on the computer.  

I don't think I want to meet the designer of, or the machinist willing to wear 
your "always active" estop circuit :)

Sorry if I ruffled feathers - wasn't my intent.

  You can have all the e-stops you want but if you happen to pick the one that 
don't work...

  There in lies the problem you assume other people have the same experience, 
knowledge and skills as you. You miss the point entirely... If the E-Stop 
button is on the screen and I'm trying to press it with the mouse and it won't 
do anything I have lost precious seconds of time getting that experience. It 
doesn't matter if I have 27 e-stop buttons all over the place if I have the 
mouse in my hand my instinct is to use it first in an emergency just because it 
is the the closest thing to my finger. IMHO it is a mistake to have an e-stop 
where ever it is that only functions some of the time.


  I think that tension sensors should be mandatory in the rear of machinest 
pants and directly coupled to the "always active" e-stop circuit. When the 
clench comes the machine stops...

[Emc-users] Getting Started with the Latest EMC2

[[EMAIL PROTECTED]]

I have just installed the latest EMC2 with Ubuntu 8.01. To get an Internet 
connection I need to install a Win XP driver for my Wireless NIC using ndisgtk. 
The instructions say to first install this using the Synaptic Package Manager 
and then to run it and locate my driver .inf file.

Problem: Synaptic Package Manager cannot find the ndisgtk package to install it.

Any suggestions

[Emc-users] E-stop Surprise

[Greg Bentzinger]

Kirk, and others doing manual tool changes.

I add an M00 after the M6 line as a second chance in case something is just not 
right after a tool change.

Case in point. The operator had set the "Kwik-Switch" spindle spanner down on 
the machine table after the tool change in a spot the tool would hit it during 
a rapid move... Gives you a chance to re-cheak that things are safe to proceed.

I even do this on a VMC that has random ATC issues where it will change the 
tool with the spindle not properly oriented so that the CAT40 drive dogs are 
keeping the tool from seating in the taper - it also means the tool length will 
be off by approx 1/4" so impact is possible/likely.

Re: [Emc-users] E-stop Surprise

[Emory Smith]

I've got two "big ole" Allen-Bradley push buttons wired in series.
One in easy reach on each side of the machine.
They're the "pull and twist" to close and "push to open" type.
They're in the AC mains circuit so operation is nearly instantaneous.
They control power to the router, motors and controller, but not the
computer.
They were about $30 US for the pair on eBay. Cheap insurance, I think.
Before them, I had run a $45 cutter way into the vacuum table (since
repaired with Bondo) and had a Roto-Zip pull itself out of the router into
the table. (More Bondo ;^)

A few of mistakes like that has made me more careful and observant and I've
not yet needed the E-Stop buttons since installation but I'm glad they're
there.

On a 'real' machine like yours, they can save life, eyes, limb and $$$.

DO IT!

Thanks for listening,
Emory

Re: [Emc-users] E-stop Surprise

[noel]

Kirk,
A physical E-stop is just about the first thing that I setup on a macahine,
even before simple testing.
The screen focus is not just a problem, it is dangerous, especially working
on 'big iron'.
A run away motor can blow a table right off it's ways.
You can add an E-stop button to axis with pyvcp.  Not too sure how big, but
with some programming it can probably be enarged.  Still no replacement for
the phyisical, locking button to kill power to the amps.
Keep contact in the button to loop with the hal signal.
Good luck.
Noel.

'In the Beginning' I just used the E-Stop input pin from the HAL,
but I was wondering if this is safe enough so I now added a 'real' E-stop.

I have a simple machine switch (one of those solenoid controlled Red/Green
button things) and just placed an E-stop button in the feed line to this
switch (it is a normal closed switch).
This combination provides power two relays: one 3-phase relay to provide
power to the servos and VFD for the spindle and one relay connected to the
E-stop input of EMC2.
So hitting the E-stop both cuts power to the power parts and also signals
EMC that the machine is stopped.

I thought that installing an E-stop was more important than limit switches
but I guess I was wrong: I need both ...

Rob

[Emc-users] Wax

[Ian W. Wright]

Hi Kirk,

I often temporarily stick parts I'm working on to a sacrificial piece of 
metal. Of course, with the small size of the parts I'm making, having a 
bigger 'handle' or something to clamp in the vise is the only way I can 
work on the pieces. I usually use shellac as an adhesive or, more often 
if I intend to do a lot of work on a piece, Cyanoacrylate (superglue). 
There are a number of grades of Cyanoacrylate, some gap filling, some 
not, and they all have one thing in common - they will release if you 
heat them a bit - just too hot to handle comfortably. the residue can 
then be wiped off with a bit of acetone. Before you use this stuff, you 
do need to clean the metal well with acetone or a proprietary cyano prep 
spray (if you use acetone it has to be plain acetone from the chemist, 
nail polish remover won't work as it has oils in it.) For anything 
needing a really good hold you can even use epoxy as most of these will 
also release with a bit of heat. I actually find that the cyanoacrylate 
glue I get from our 'Pound stores' - presumably your 'Dollar stores' - 
where I get 5 little plastic bottles of a very fluid glue on a card for 
1UKP, is actually the best I have used!

Well, the Dremel's collet and speed steer you to a smaller size 
endmill.  I used to get 1/8" 2 and 4-flute endmills in solid 
carbide for about US $3.00.  They probably are more, now.  I 
would buy them by the dozen at one of the eBay sellers like 
Reliable End Mill, I think they are now Relaibel Tool.

It may be in these materials, that standard Dremel router bits 
would work fine, these should be available at hobby shops, 
hardware stores, etc.  In these sizes, you are not likely to 
find roughing end mills.  Ballnose mills are good for profiling 
3-D surfaces.  You probably won't find junk in solid carbide.
There were some true junk in HSS end mills with 3/8" shanks, in 
square blue plastic tubes with the size rubber stamped on a 
paper label.  These were the worst crap China ever made, and I'm 
insulting the sight-impaired by saying they looked like they 
were hand sharpened by an 80-year old blind man with shaky hands!

You really HAVE to have a hardware E-stop!

The business with the pointer focus on the GUI is pretty 
dangerous, and I run into it all the time.  Usually just hitting 
Enter will get your focus back to the main GUI window, but that 
is still dangerous.

Given how the windowing system works, I don't think there's a 
way to do what you want.  Put in a harware E-stop button.

Sorry if this is a bit OT, but I'm stuck. I have EMC2 running and my CNC 
machine assembled and now it's time to try cutting. I want to focus on 
wax and wood and start with some pine. I'm using a Dremel for the spindle.

I've been reading the CNC forums and various websites but I cannot 
figure out what kind of endmills I need. Can anyone give me some 
pointers? Is there a beginner's guide on the web somewhere? All I want 
to do at this stage is:

   - cut objects in pine

   - expect to break a few endmills so looking for cheap

   - want to avoid junk endmills

   - not sure when you would use a ballnose mill

   - difference between endmills for roughing and finishing

I expect to be cutting parts that are perhaps 20 - 30mm on each side 
with the smallest feature perhaps 2mm. My scrap pine for testing is 3/4" 
thick so I guess I have to do some pocketing before cutting.

thanks, Andy

I suppose there is some technique that needs to be developed to use wax
properly. The bound can be fairly thick and uneven, so if flatness is
important the clamping setup is important too. I also have to work on
the part clean up. My guess is that Mitee-Grip has worked it all out.
I'll check it out. Thanks.

Try Dop Wax, from lapidary suppliers. It's a replacement for the 
traditional shelac, which shatters when it's bumped. It's a lot 
stronger than parafin. It's primary use is for grinding the facets on 
gemstones, which are held on the end of a stick, or dop, with this 
stuff.

The g-code had a normal Tx M6 so the machine would have paused for the
tool change if I had the appropriate .hal setup which routes the
toolchange - toolchanged signals to some sort of conformation feature. I
knew this might be a problem, so I just tried to be very careful to be
ready with the e-stop button. Normally, I use the F1, but this time I
was ready with the AXIS button, or so I thought. I have a proper
hardware button on everything else, I just thought being careful would
be okay. That may be how the Challenger blew up.

Kirk,

I have some stuff called "Spann-Folie" in German. I bought this from
Sartorius in Germany.
I friend of me used it also to create round disks of a few milimeters thick
on his lathe.
The label on the packaging tells me it's called
Mitee-Grip.


Works perfectly well.

This stuff makes milling small or thin pieces an easy thing to do.
The only hassle is that you first need to press workpiece and sacrificial
plate together and heat then to about 90 Celsius.

Yep, there should be an easy way to kill the power to the machine.
And it should be in reach of your free arm while the other one is being
broken by the machine ...

I also use separate programs for different tools.
Today I just tried the T02 M6 cycle but somehow the pointer showing the tool
location disappeared from the axis window.

Wow - I guess I should be proud of myself that I had a physical estop button 
and a machine kill switch designed in while things were still on the bench!

Ok, enough bragging - get your physical estop button - that button, even one 
of the high dollar ones, is worth its weight in gold compared to the damage 
it can do to the machine (or you) if things go awry.  I wonder - did your 
program actually specify a new tool (ie m6  t02) or just an m6 with you 
knowing what tool it needed next.  My mill stops on the M6 T2 that was 
generated by CamBam and waits (typically I'd been handcoding and doing 
separate programs for each tool since I don't have an automated touch off 
concept in place yet).  I'm not sure what the manual says about the M6 
command but maybe somewhere in the code the toolchanger portion realizes the 
tool is the same as that currently specifiec and lets the program run on, 
though still pops up the window for the toolchange.

I'm still spoiled by the keyboard - I hit escape (and usually tap it 
multiple times as I'm used to being deep in autocad levels of commands that 
I wanted to end) and if necessary F1 more often than I use the mouse, when I 
complete my operator's station I'm going to need to add another E-Stop 
switch in the loop as I won't be within rapid reach of the one on the 
controller anymore.  My thought is you should have a mechanical estop in the 
loop anywhere you might possibly be while the program is running 
(ie:console, enclosure, spindle) so that you can always stop it.  You just 
have to train yourself to use them.

Hope you learned your lesson and we figure why that happened and get 
anything that needs to be corrected taken care of.  Maybe all the OK's 
should be on a common "message center" with an Ok and the background of that 
changes color when a new message is displayed and then goes to a standard 
background when everything is cleared.  Just a thought, but I also think an 
M6 should stop regardless of what tool is in and what tool is scheduled. 
The interface has no way of knowing definitively that something wasn't 
changed.

There's my .02x10^-23 - YMMV.

Re: [Emc-users] Wax

[John Thornton]

Kirk,

I do this often in my shop. I keep many pieces of sacrificial aluminum plate 
around. 
On parts with a profile I drill all the holes in the part while square then use 
at least 
two holes in the part and then mount it to the sacrificial plate which is 
mounted into 
the vise. Then I cut the profiles going 0.025 - 0.050 deeper than the thickness 
of the 
plate(depends on the radius of the edge of my cutter).

Re: [Emc-users] E-stop Surprise

[John Thornton]

Kirk, 

I ran into the same problem with the popup message about ... I forget the exact 
message but I rammed my carriage into my rails because the popup took focus 
from the main window and I clicked on the main window trying to hit the e stop 
button but it was not possible. I was not familiar enough with EMC at the time 
to 
know to hit the escape button and don't know if that is blocked too. I also was 
in the 
process of learning EMC and setting up my machine. In my case with steppers 
nothing was damaged. I still belive it is a bad practice to use popups and feel 
that 
all messages should be on the bar at the bottom and flash in red if a warning.

If you're still looking for screencasting software take a look at 
recordmydesktop. My first attempt can be found on google video for
a limited time.  Search terms synergy+cad should find it.

The narration is, errrregrettable, and google video does it's 
usual terrible things to video quality.  That "ABC" synergy output
will in fact run if the tool diameter in emc2 is set to zero.

Synergy is not working well with 8.0.4 on my machine. After running 
in color a few seconds everything goes grayscale. Maybe a case of 
switching on too much eyecandy?  Hardy Heron has a ton of that stuff LOL.

[Emc-users] E-stop Surprise

[Kirk Wallace]

My mill isn't fully functional yet and I neglected to realize the
ramifications of this. A bracket I needed to make required a tool
change, so I decided to just do it manually. I checked the program by
lowering the knee and single stepping through the program, which at the
time seemed okay. I raised the knee, started the program and drilled the
holes. The table homed for the tool change displayed the tool change
message and proceeded to go ahead with the program without stopping.
Unfortunately, the new tool that didn't get changed is shorter so the
tool collided with the table. I tried to click the e-stop button in AXIS
but it had no effect. Then I realized that the tool change message had
the window focus and I needed to clear it before the e-stop would work.
I realize I made a few mistakes here, by not having a proper config file
and a hardware e-stop button, but I wonder if there should be a way to
have the AXIS e-stop always on top and available.

[Emc-users] Wax

[Kirk Wallace]

I needed to mill a bracket from 1.5mm (.060") aluminum and decided this
might be a good time to try mounting the material with wax. I dropped
some hot candle wax on a 13mm (.5") plate and then placed the sheet over
it and used a propane torch flame on the sheet until the wax started
running out all of the edges. Then I pressed the sheet to the plate
until it cooled. I clamped the plate to the table and drilled the part
holes and milled the outside contour. It looked like I didn't mill
through, so I milled the contour again a little deeper and half way
through the last pass the part broke free. Fortunately, the part just
jiggled on the end-mill instead of catching on it and flying off. Since
this wax was not designed for this purpose, I would say this process has
promise. I hate clamping thin parts in a vise. Has anyone tried a
different wax or method?
