I have a half-baked idea for AXIS
tonight I was rounding the corners on a large plate using MDI arcs
I would place the tool touching one side, say an inch from the edge, and then I had exactly one chance to get each arc right
I wonder if AXIS could show the path about to be generated by an MDI command in the preview, and then let you accept or reject it
for many MDI commands, it seems like you wouldn't want this extra step, hence the half-bakedness
fortunately we're in the feature freeze so I'll just file that one away for later...
oh I know, but I wonder what you think of the idea, whether or not we want to do it later
R2 shows "CW" or "CCW" when you enter G2/G3 so at least you have that - in emc, you don't get any help at all
well .. that way lies the g-code editor with interactive preview
because next is "I'd like to enter a few moves and preview it before I run it"
not sure I agree
we can already preview a set of moves before running it... I don't get the distinction you're making
why don't you write your one command to a file and load it in preview, then?>
no new feature needed
it's true I could do that
jepler: another one to file... I would like to see the cursor co-ordinates displayed on 2d axis displays.. statusbar might be a good location... what do you think? good/bad idea?
LawrenceG: I am not sure what you mean
like when in Z view, you'd see X,Y as you move the mouse?
when previewing a file in axis... I would like to be able to see what the co-ordinates of some feature are....
like the edge of a circle, a corner etc.... yea, in z mode, one would see x,y
you know that you can click it and see the corresponding line of gcode, right?
when you look at that line and the previous line, you usually have exactly that information (and more)
yes... the function would be used in a poor mans layout.. I'll pastebin an example I was working on today...
hmm not for complex gcode
I take it back
this function would only make sense in a "plane" view, not in "perspective" view

... layed this out manually... it holds my er25 collet set
hmmm... it ate some of the lines...
I made a very similar part yesterday/tonight
much bigger though :-)
23 ER40 collets plus some other taper holders
cradek: stop bragging
it's cool, I should take a photo
LawrenceG: do you have it cut yet?
shoptask is only a baby... er25's are a good size... yes, sitting in front of me
LawrenceG: it looks like it resizes the image if your browser is not wide enough
want a pix?
I spent too much on my laptop display so it looks fine
LawrenceG: did emc accidentally try to cut it at 40ipm due to a stupid bug? if not, you're ahead of me
I guess I am resistant to features that take AXIS in the direction of being a really awful CAM package
jepler: I can't argue with that
because no matter what it will never be a *good* cam package
no, I cut at 8ipm... no scrw ups with a couple of day old build from cvs
the mdi preview is more 'conversational' than cam, but point definitely taken
cradek: I meant to ask, you used F4. and F4.00 in your example. What does F4.0 do?
I was too scared to try F4.0
(I knew F4. would work)
I keep meaning to look in the manual and see what it says about F
Is bp limited to integer speeds?
LawrenceG: I don't know, but if you program F4.00 it cuts at 40
the . is required
I bet it would take 4.0 (or 4.5) but not 4.00
I'll go take a photo of my holder, brb
g1f10.00 x5y5 seems to work... at least in sim
actually if your window is too wide it stretches the image and still makes it look like hell (imagebin.ca)
LawrenceG: I'm sure it works fine in emc
cradek hasn't started his retrofit yet
how about a background grid ( like the limits )
"It's like a pregnant woman laughing at me because I have gas." -- what the hell does that mean? (seen on a web forum)
I guess I could always put g0 moves and draw a grid and comment them out when running pgm

picture of er25 set... now I need to make a box

hm should have rescaled...
the second one is the mill in its (more) final location
there's a second row for 6 more holders behind, but they're covered until it's mounted properly
cool.. it fits well in the garage
yes it's a good size machine for that space
it's still out from the wall far enough to get the back door off and work on it (a little cramped)
cradek: did you buy some collets?
(looking at the picture)
skunkworks: yeah you can see the set there
they're supposed to hold all sizes from 1/8 to 1, but I'm not sure I believe it
heh - they are'flexable' :) nice
yep, so they say
er25 set holds 2mm-16mm or about 1/16 to 5/8"
the tool I've used 10x more than anything else is the 3/4" 2 flute aluminum cutting end mill in the center of the back row
do you mostly use the 5/8?
yea that baby must throw some chips!.... 5/8 is about as big as the shoptask turns easily
I mostly use 1/4" or 1/8" bits
after cutting this I had aluminum everywhere for 8' radius
but I have a bunch of surplus 3/8 endmills
I did a lot of sweeping so I don't track it all into the house
I made my holder from 3/16 lexan.... shopvac stopped shop from becoming full of snow
I cut this 1/2" plate with a 1/2" end mill (actually 0.482 resharpened junk) in one pass - plunge and make a circle for each hole
I was surprised it cut so easily (with coolant)
cool... power is nice
LawrenceG: I have trouble cutting that stuff without melting it to the tool
1/2" deep with a 1/2" mill is pretty optimistic but it worked fine
very sharp hss cutter an either an air blast or shopvac sucking for cooling
2 flute right? or 1?
just a 1/4: 2 flute endmill from some cheap set

and now .. goodnight
interesting ... goodnight
working backward it looks like I was cutting 250sfm at .001/tooth (2000rpm, 4ipm)
for production that's a bit conservative but I'd need good flood coolant to do more I think
at this load it wasn't working at all, just a gentle hum from the motor, but I had some trouble keeping it from gumming up with my spray bottle of coolant
yea... I have a bunch of assorted Al here and some of it cuts like crap.... other stuff makes beautiful chips
cradek: when cutting lexan you need to take a fat chip
the gummy stuff makes for broken cutters
LawrenceG: luckily this plate said 6061 right on it
thats a nice piece of aluminum there
yeah it was a nice find
and you went and put holes in it!
it was part of a "worthless" triangular drop
as I cut more stuff out of it, I have more triangles
(it's almost gone now)
depends a lot on how it has been heat treated as well.... T6 or ?? most of my stuff is from dumpster diving
gussets! you just have to find something that needs braced
what is the motor looking thing to the right of the shopvac in your mill pic?
haha you can see a triangle in the background
(under the electrical panel)
a backpack type pesticide sprayer that might be somehow involved with flood coolant
* jmkasunich_ guesses rotary phase converter
oh that, heh
I didn't actually read your question
yeah that's the converter
"motor looking thing"
yeah I see that now
it'll be nice to get rid of that eventually, but it sure works
I see you got one of those little screwless vises
to the right of the panel is another panel with the control stuff for the converter
that's a sherline vise!
emphasis on little
I was going to use it to mill an angle on something but didn't end up doing it that way
is the red rag on the knee handle a warning flag?
or just a handy place for a rag
just a handy place
I haven't run into the handle yet
I was religiously taking it off for a while, but now I generally leave it on
I think it helps that it's toward the left (wall side)
(I have a bad habit of throwing the rag on the table, letting it collect chips, then cutting my hands with it)
I use paper towels instead of rags
yeah I have both, usually like the rags better because they don't tear up
that photo looks like I'm one of the anal guys who cleans everything all the time
when actually I just cleaned the table so well to put the vise back on after this job
what is the cutter at the top left of the first pic?
looks like a shell mill
it is a shell
but that toolholder and shank combo makes it seem like its flopping around on the end of a stick
I got it in some junk and use it instead of a flycutter for facing
yeah it's really janky, it's a welded shank that someone slapped together
it's a nice cutter though - maybe I can get a real holder for it
something that doesn't put the cutting edge 6" away from the spindle nose
facing at 10x the feed of a flycutter is nice...
I do 12x ;-)
I counted the teeth and I'm pretty sure it's 10...
and 5.5" wide
next year I'll bring you the stuff too big for me to use, I have some from that auction
[03:44:37] <jmkasunich_> http://www.metalworking.com/dropbox/_2001_retired_files/Facemil1.jpg
my machine isn't really any bigger than yours
with the right holder I might be able to run that.
although I have a 1" horizontal arbor, so I can run that kind of cutters
HGR I presume
[03:46:41] <jmkasunich_> http://www.metalworking.com/dropbox/_2001_retired_files/Face_mill1.jpg
how bout that one ;-)
we need to take some pictures :) shell mills are nice.
about that - that one isn't mine
although I don't think we have anything bigger than 12.
(there was a thread on rec.crafts.metalworking about face mills, several people posted pics)
including at 96" one: http://www.metalworking.com/dropbox/_2001_retired_files/facemill96.jpg
my shell mill is bigger than your shell mill :L
Mr. 96 won
this 10" hasn't been used for a very long time
"this" meaning one that you have?
no the one in your mill1 photo
yeah, its a bit dusty
time for bed. just spent a good 4 hours cleaning up a xp machine.
skunkworks: I've got a CD you can borrow that does a quick job of that
I have one here.. but it would be less than 4 hours :)
err I mean goodnight :-)
some unreasonable fool probably wants it to have XP on it afterwards
the nasties are getting nastier and nastier.
skunkworks: I don't see how you can ever be sure everything is gone, short of reinstalling
when the virus software stops randomly finding viruses and IE acts 'normal' I call it good.
(and yes that was 4 hours)
heh - night.
but will it be back in your hands for the same in a few months?
this one has been about a year. not bad.
thanks for saving us all from spam from one more 0wned windows machine
someone clicked on something they shouldn't have.
yes :) no problem.
... 100 times
I forgot I had posted this: http://www.metalworking.com/dropbox/_2001_retired_files/JMKCOL1.jpg
now -really. Night.
cradek: you could build a box around your plate
jmkasunich_: box you made?
keep the mill jewelry clean
nah I think I'm going to screw it to that table and call it good
also made the collet holder and wrench
[03:55:39] <jmkasunich_> http://www.metalworking.com/dropbox/_2001_retired_files/JMKCOL2.jpg
the collets are a swiss screw machine set that I got on ebay
what's the scale? is this for tiny stuff?
the set goes from 1/32? to 15/32, by 64ths
ok much bigger than I was thinking (looked like WW collets)
the outside of the holder is a Morse 3 taper
little over an inch at the big end I think?
I have yet to have to cut a morse taper (thankfully)
I take that back, morse 4
is that your shoptask spindle?
same as my set...mt3 er25 holder
the headstock of the shoptask is 4, the mill spindle and tailstock are 3
I didn't cut the morse taper, I bought a cheapie MT4 to jacobs something adapter
yeah, no kidding
so the shoptask has no drawbar? just morse?
the mill spindle has morse 3 with a drawbar
it has a drawbar....
the lathe spindle has morse 4, and a flange with a locating step and 3 bolts
the flange is used for chucks and faceplate
morse 3 has threads in the back? I'm confused
morse 3 is the taper
morse drill bits have a tang in the back
ok that's what I'm used to seeing
but you can get some tooling that is drilled for a drawbar instead of having a tang
internal threads in end or mt3 shank
3/8-16 for the shoptask
think the new drill press is MT3 but no drawbar of course
thats a beefy drill press
you need to pose a pic sometime
my 300 lb 15" clausing has a MT2
not sure what came with my er25 set... it looks big... maybe 12mm
I need to make a new drawbar
(threading on a non-CNC shoptask sucks)
LawrenceG: drill and tap yours and put a long "setscrew" in the end with loctite
yup.. or get my spindle encoder hooked up!
next time it's worn out, just replace the screw
cradek: I've done that trick before, works great
IF the bar is big enough
I have that on max - never had to replace it yet :-)
the hole thru the mill spindle of a shoptask might not even fit a 12mm bar
trip to harware store that stocks metric bolts?
I stand corrected, it's about 13.9mm
sounds quite possible then
still, that isn't a lot of metal outside the threads
13.5 mm bar with a 12mm threaded hole in it?
the hole pretty much takes the whole end of the mt3 shank
3/8 is 9.525mm
brb... going to try a 1/2" bolt
LawrenceG is trying to make a 12mm threaded drawbar for his ER collet holder
I thought he was repairing a 3/8-16 drawbar that goes in a 13.9mm hole
on that note, I should go to bed
1/2" is close... need finer threads
1/2-20? or metric?
not sure... will try and find my thread guage
well, I'm gonna find some shut-eye
goodnight, and good luck
looks like m12 1.75mm pitch threads (12mm coarse standard)

I'm not sure how I feel about this
that gives USER_UNIT grids on the preview plot?
oh - settable spacing
[21:17:41] <jepler> http://emergent.unpy.net/index.cgi-files/sandbox/axis-grid-rev2.png
how does it look in perspective view?
it doesn't appear
if it's a checkbox somewhere easily accessible, then I'd put it in
I can see that it might look "cluttered" sometimes, but it would also be very useful at times
right now you have to enable it by putting an (AXIS) comment in your gcode source..
oh. that's an interesting way of doing it
I'm not sure if that's a good way or not
me either, but it is interesting :)
* fenn suggests a brighter line every 10th/100th line
also i think it's off by a factor of 2
note the line "(AXIS,grid,.5)" at the top of the g-code listing
it's a .5" grid
