ren_encee is now known as renesis
dang, I need chip shields
running the K-Tool facemill at something close to rated speed, and about half of rated feed, chips everywhere
jmkasunich : Or a great vaccuum system
I added a high-flow vaccuum system next to the milling head on the tormach
makes cleanup a snap
it would need a nozzle that could wrap around the tool and clear all my clamps and such
I just made a soft hood with "fingers"
similar to the one found on a shopbot
my setup is probalby to awkward for that
the fingers can get around the clamps, and the skirt is made of easily replaceable abs plastic sheeting
Still, I've had mine on for three days now, and love it.
Then again, I run a constant flow of coolant over anything I'm cutting, so a lot of the chips just flow down into the filter
I can't use coolant (shoptask machine, it would wind up on the floor)
That's a pity :(
that cutter rocks
I just took off about 0.080 of cast aluminum at 15 ipm, then made a 0.015 deep finish pass at 20 ipm

* voxadam had never seen a Shoptask until a couple of minutes ago.
It's a monstrosity.
yeah, it is
Or at least it looks like one.
not a bad lathe, so-so as a mill
it isn't very rigid in mill mode, but if you use carbide cutters and keeps speeds up, it can do well
mine has earned me at least 10x what I paid for it, so I can't complain
Can't argue with results.
the main problem with it as a mill is the lack of Z travel
3.3" of travel
that's why my work is sitting up on blocks all the time
3-in-1's are never terrific at everything
[02:31:07] <jmkasunich> http://jmkasunich.com/cgi-bin/blosxom/shoptask/spindle-encoder-bracket-01-07-08.html
another typical setup ^^^
the only thing they are good at is fitting in cramped basements
a bport and a decent lathe would never make it down the steps
Point well taken. Disassembling and reassembling a bport is a royal pain.
even disassembled, what does the base casting weigh?
the whole shoptask is about 700 lbs, I took it apart to get it downstairs
probably the biggest piece was 300
300-400 for the base casting
for a bridgeport? you gotta be kidding
no, the shoptask...
Bridgeport is a multiple of that :)
Not something I'd like to be lugging down a set of stairs.
the base casting on my Van Norman #12 (smaller than a bport) was 723lbs
that machine lives in the garage (where I fight a battle against rust)
tomp is now known as tomp3
I wouldn't want to either.
It's why I chose to buy a used tormach.
they seem like nice machines
out of my price range tho
You can occasionally find them in the 6000->8000 range
The one I bought was being used as a supplemental machine next to a vmc
to help speed up process
how to make a cheap 'knee' for shoptask? , naw, i bet 4 pcs 1-2-3 blox are as good as anything
I just recently got a pair of 2-4-6 blocks, they help a lot
but it can still be tricky, when a job uses one short tool and one long one
the arbor extension that came with my shoptask just exaggerated the runout
and eliminated whatever little rigidity the millhead has
I've never ever used that thing
I bring the work to the spindle, not the other way around
yep, more solid
i might look at this (mini gantry) X-200mm Y-150mm Z-60mm $468 USD (15800NTD) http://goods.ruten.com.tw/item/show?1108081559267
just to get some test unit thats more portable than the shoptask
broken link (displays some error message in chinese)
hmm same here, try this now http://goods.ruten.com.tw/item/show?11090423859788
how much is that in USD?
i see theyre on usa ebay too, for 500 but that doesnt include shipping of 11kg ( im leaving taiwan soon, and they're near the airport)
tomp3: looks flimsy
11kg? lol - very very flimsy
yeah? i thought thos thompsons would be ok, and plate alum sides
sorry, I misunderstood your original statement
I thought you were looking at something that was similar in capabilities to the shoptask, only smaller
I can't take seriously any gantry mill with side uprights that are cut out of a single flat plate
those flats are weak against Y axis forces
i was comparing it to zenbot
jmkasunich: does the carbide let you get up above the resonance of the machine?
I think so
maybe not above resonance, but fast enough that the weight of the head absorbs the forces, rather than relying only on the stiffness of the column
I need to set up the webcam and make a vid tomorrow
like a wood router I guess
yeah I'd like to see that
I'm doing the carb end (face, drill, and chamfer) in less than 5 minutes, including tool changes and part load/unload
the facing is less than 1 minute of spindle-on time
the chips they do fly ;-)
neat. you will be done in no time.
52 x 5 minutes still = the better part of 5 hours, and that is just for the carb end
I thought it was 48 - they're breeding
the foundry casts them 6 at a time, I guess they did 9 flasks instead of 8, probably in case of oopses
I hope I don't kill the motor start caps
they look like good castings.
5 minutes per part = 12 per hour = 24 starts per hour
cheap-ass chinese caps don't like that much
they are nice castings
the chips break nicely - I don't have to peck or anything for the drilling
chips just come flying out of the hole
I'm feeding at 6ipm for the drilling, just over 0.001 per flute
no, carbide drill-mill
I think castings can dull HSS - embedded sand?
and high silicon content
I'll have to see what the inserts on the facemill look like after the job is done
that thing has $26 worth of inserts in it (but each insert can be indexed 8 times)
ha, that's nothin'
I bet mine has >$100 (indexable only twice)
worse design I guess
this one is only 1.5" OD, and the actual flat face is 1.125"
2.5? I don't remember
pretty big (8 inserts)
I just took a pic of the surface finish...
[04:05:20] <jmkasunich> http://jmkasunich.com/pics/carb-end-machined-2814.jpg
the pile: http://jmkasunich.com/pics/manifolds-before-2812.jpg
is that flat enough?
wth kinda manifolds are those?
JymmmEMC: for one-cylinder minibike engines
AH! okey =)
cradek: it's pretty darned flat - the "lines" aren't as deep as they look
I thought the other end "stack bolted" together! lol
if anything, the lines will just give the gasket something to bite into
oh, wiat. nm
Gorilla snot goes on the cover gaskets =)

Great Stuff btw
sounds like a good idea actually
heh, it worked
i got my uc stove controller working today
how's the girlfriend?
still persistently stalking me
did you tell her?
hey any developers online?
evo4wrx: but it's always best to just ask a question, then wait for someone to answer it
i thought as much.....
bit of a time difference toos ince im in australia
evo4wrx: anything specific you had in mind?
bbl.. lunch here
building a larger type lathe...well turn mill to be more specific.....after a developer to code me up some hobbing specific apps or macros
what is a turn mill
4 axis lathe
guess I've never seen one before... sounds neat
pretty much a 4 axis mill...except the rotary axis is a spindle capable of some decent rpm
that way you can use turning cutters
does the LiveCD create a dual boot if you want it?
I suspect it can, since the stock liveCD can do that
sure it does
that's the way I don't run it ;)
quite a few people making their own simple h-bridge. http://cnczone.com/forums/showthread.php?t=25929&page=25

yea, I don't want no stinking windoz on my linux computers :)
alex_joni: the forum has been busy today :)

is there a way to force Tkemc to display active text plus 1 or the next line to be executed?
nap time here
Howdy guys, that bad penny from WV is back!
Got an acme screw question. My z drive has 2 bronze nuts, about 3.5" apart, for backlash takeup.
Backlash is a little under 0.001" now. But its shimmying gently on the down stroke at aboutr 9"/min
lub is stp at the instant, and grabbing the screw with my hand doesn't seem to effect the shimmy.
"shimmy" oscillation back and forth ?
something like that, a low level vibration at about 25hz I'd guess
A lighter lube, once it has a chance to work into things does make it worse.
my first thoughts are adjust pid loop or add some deadband compensation
It doesn't seem to effect the work in progress, no, steppers, 425 on that axis, geared down 17/42, 10tpi 1/2" screw
archivist presumably u didnt go to the RAL uWave meeting today?
work in progress is a 2x6 with 144 3/4" deep, 1/2 diameter holes, for a cartridge loading block.
So its not exactly a fawny auction item. :)
So its not exactly a fawncy auction item. :)
gene, if stepper then resonance /noise while moving is not uncommon, move at a rate where the noise is least, make sure the drive has no play
I have some of the dampers similar to the ones Jeff at xylotex put on his mill, they work sweet. I can actually see the screw vibrating about 5 thou or so.
You can see those at <http://gene.home.linux.net/gene/emc>
You can see those at correction, <http://gene.home.linux.net:85/gene/emc>
gene.home.linux.net could not be found. Please check the name and try again.
damn "homelinux", no dot, I can't type obviously
this should be correct, you can see those at <http://gene.homelinux.net:85/gene/emc>
can see pics now
Good. The uplink bw ssucks tho. :(
Nother q, about pass 's' params, in main: #39=600
in call, 9th param is [#39]
in loop: s#9, but gets a zero, what the heck?
does the 8th parameter pass correctly?
exact same syntax seem to work for the 'f' values...
wait, what do you mean by "S" and "F" parameters?
yes I believe so, that is S=spindle speed and f=machine speed
there are only parameters
#1, #2, #3, etc
you can use them for anything: G0X#1 M3S#2 F#4
if #9 is getting passed correctly, then it won't matter whether you are using it for S or F or anything lese
and if it is NOT being passed correctly, it still won't matter
I'm passing them in the call:, and copy paste ate me. 1st 3 calls don't get it, brb.
Yup, fixed, I'll go quietly officer, just as soon as this job is done.
and from the mailng list I've been given that s must be set on a previous line to take effect at the M3.
So that is the way I'm going it, works fine. Drilling 144 1/2" holes in a short 2x6, for cartridge loading.
I'm finding that a Forstner bit likes a decent feed rate, its running about 600 rpm, and 10"/min feed. Nice holes.
darn, the spindle electronix just did an overcurrent shut down. Set it back to 800 I guess.
nope, passed wrong argument, so it was turning about 25 rpm on pass 2, duh... :(
good night all

15:38 < gene_> hey guys, great if warm day here, but have a gcode problem
Can I help you?
I did not write that. I think I have a gremlin.
Ah. You accidentally pasted something that gene had written.
Yeah. I have my desk covered with pipe fittings. I am pluming the shop for air. I must have set something on the mouse.
