looks like the genserkins linear motion all works (from a very quick play with jog in axis)
theorb is now known as theorbtwo
hey Dave911, how's it going?
-- I saw this machine
L84Supper: note that the servo controlled 4th axis is NOT included in the lot.
L84Supper: I am not affiliated with seller
ichudov: "CNC tapping center" ? interesting model
ichudov: thanks for the link....hmm in Dolton. I'm heading down near there to pick up a lathe soon
you mean the battery powered bunny drum set with a microcontroller inside it? :D
well, the 308 has a color monitor... but has an alarm atm that I need to figure out
JT-Hardinge: alarm atm? Does it make and dispense $20 bills?
JT-Hardinge: What type of alarm? Alert or lockout?
ichudov: we have a used CNC dealer right next door, they have about 100 machines listed but no bargains yet.
just says alarm...
JT-Hardinge: Is it asking for a code?
no, it wants air lol
JT-Hardinge: Well, stop holding it's head in the toilet ya bully!
JT-Hardinge: you move it along on a trailing making it trailer trash. Pushed it around using a ho, and now hold it's head in the toilet. I'd send out an alarm too!
I just have to figure out how to run it now LOL
JT-Hardinge: RTFM! lol
I got it to home and move so far lol
does it move 1" when you tell it to move 1" ?
cradek: ohhh, remember me programming this 2 1/2 - 8 NPT a few weeks back?
we ran it today, in my excitement the taper amount posted right, i never noticed the fact it posted it as R-.00559 which is nice on a OD thread, not so much on an ID thread......going to see if the post processor is hard coded to always put R- :)
anyone want to test my hack?
[01:18:47] <moopy> http://soundproofingforum.co.uk/halitosis/
it is still shit, but the genserkins has been updated as seems to work for prismatic and revolute joints

anybody need a brushless DC drive?
AMC model # BE15A8J
mikegg: Where (internet) is it offered? Where (geography) is it located? How much (money)?
skunkworks: Are you around?
not listed yet. just sitting in my tool box. part of my severance package...
convince me it will do more than gather dust in my garage and make me a fair offer. atlanta
oooh, or how about we barter for it!? got anything shiny?
Well, I'll think about that, what do you need? I was really asking for skunkworks, who I thought might be interested in it. But I might be interested too, if the price and power specs are right.
oh finally! I got emc2/motmod.ko to load on x86_64 with acos (whatever that is)
the rest should be pretty easy now!! http://pastebin.com/cb08HhhM
EMC wont start still though... at least I don't need to run emc as sudo.. im a lot further for once. I keep getting /usr/bin/emc: line 654: 2976 Segmentation fault $EMCTASK -ini "$INIFILE"
mikegg: too bad you are in Georgia. I am in Ontario. I would love that brushless DC drive.
interesting severance, though. did the company go belly up?
We are installing an EMC NS-480 for our vSphere 4.1 environment. Trying to decide if FLARE 30 is ready to go, or if we should hold off. Anybody have any experiences?
I really should read the subject first.
L84Supper: I do not really expect bargains from dealers.
Made a high speed spindle adaptor yesterday. I need a chip auger! :) http://igor.chudov.com/projects/Bridgeport-Series-II-Interact-2-CNC-Mill/29-High-Speed-Spindle/
can the quill still go all the way up with this bolted on, or do you have to be careful?
cradek: I would have to be careful.
I would like ideally to be able to sometimes set Zmax to be a lower value to accommodate this adaptor.
Which means, I would home without it, then put it on and set a lower ZMAX limit.
ichudov: since 2007 we've been talking about that - a way for the user to set a temporary soft limit inside the normal soft limits set up by homing
I agree it would be nice
[14:34:42] <cradek> http://sourceforge.net/tracker/?func=detail&aid=1491243&group_id=6744&atid=356744
oh, so it's a relatively new feature request :P
there's a little discussion in the comments here that is more or less out of date
cradek, ichudov just two hours ago, i was thinking about quite the same :)
I would really like to add a couple of things to EMC. One an optional GUI feature so that if I click a mouse on the plot, it would display coordinates of the point where I clicked. Say, if I am looking from Z down, it would display X and y. Makes some debugging easier.
cpresser: great minds think alike
that would be cool (but only makes sense in the planar views I think?)
also if a gcode line is selected it would be neat if the preview would somehow display its endpoint coordinates and possibly the center if it's an arc
kind of an extension of the extents dimensioning we have now
Yep. It is really just an AXIS display issue.
center if it's in the window
maybe a line from center to arc with a -> and the radius value, somewhere close to the line
Another thing is I would like to add a search path to search for functions, as opposed to just one directory
like $PATH in Unix
That way we could have multiple function libraries
ichudov: that might open some can of worms
what if the same function/file exists more than once, etc..
(you can probably solve the multiple dirs with symlinks)
we already have that path thing
I am looking for a spindle for my cnc, i really have no clue what to choose or things to consider could someone help me in the right direction ? :)
dgarr did it not long ago
cradek: have you looked at the changes that I emailed you for truetype-tracer? I want to make add'l changes
Oh I did not know, what is the name of variable
yes, I liked the changes
I just wanted to make some minor extra improvements, such as printing a comment with all command line arguments that were used to produce this output.
That way it can be rerun easily.
that's fine, please do
Then I would try to take a stab at raised letters, with your guidance of course. But I would really like you to release a new tar with changes, so that I am not working from forked code.
I keep all my stuff in CVS generally.
with heekscad being able to pocket around ttt letters now, I'm not sure that should go in ttt. It seems like it would be very complicated.
Do you keep ttt in some kind of git?
I will not do raised letters then.
sadly I've never set up a public git for my projects.
no prob. I will keep your source in my personal CVS, and will mail you changes when they arise.
does anyone know what the CPU load is for AXIS to determine where the mouse was clicked in the preview? (which it does for segment hilighting at the moment)
for planar views, it should be easy to have the mouse position (in CNC coordinates) tracked on the status bar or somewhere. the screen is a 2-D map of part of the coordinate space, with some offset and scale
so each pixel corresponds to offset+PixelPosition*scale
in world coordinates
anyone use wifi with their 10.04 install of EMC? my machine is in the garage and it uses a D-link wifi pci card, just wondering if it is supported. it didn't work with the 8.04 version, possibly just a missing module though.
elmo40: it will probably work fine. I urge yuo to run a real ethernet cable to the garage, however.
I would only use it for updates or software installs. when not needed it will be off.
not like I will stream audio while the machine is running, that is what a radio is for ;)
That's what a computer is for. :) I personally play music on my mill from an NFS share in the basement
but not when milling, that's where I draw the line.
I try to streamline my system as much as possible. remove totem, rhythombox, other things that consume space and/or resources.
the nv driver is good enough? or should I use something else with the old nVidia GeForce MX440 w/128Mb RAM
morfic: Hi Morfic.. I'm fine.. :-)
what is emc2-install-sim.sh ? I don't understand the 'sim' part of it.
elmo40: I would use a proprietary driver
si mmeans it is an easy to use simulation install. I have it on various desktops that are not connected to the milling machine. I use them to preview G cde
so I shouldn't use it on the shop machine but I should on my desktop.
started the 10.04 install at 11:50. will see how long it takes.
elmo40: right, use it on your desktop, laptop, lapmtop
install completed. took 25min. nice time!
now for the script.
Yea! the pull studs should be here today!
anyone here know how to reset an alarm on a Bridgeport DX32 controller without just pulling the big handle on the side?
[17:39:07] <Jymmm> http://www.youtube.com/watch?v=CtZKL74LgMg&feature=player_embedded#!
JT-Work, try the reset button if there is one, that should reset the alarm buffer works on most other controls iv used
doesn't work on my controller. well, for the most part anyways. if the alarm is still tripped it won't reset.
on an older bridgeport, you homed again to clear it
* jepler finally spends long enough with gschm+pcb to get from schematic to layout. http://emergent.unpy.net/files/sandbox/gschem-pcb.png
now how do I get from a routed layout to a part program..
can you save it as a dwg? then you could make traces from that
if dxf, maybe heeks could pocket it
pcb -> gerber -> pcb2gcode gave me output that looks at least somewhat plausible
[18:47:26] <moop> http://www.brusselsprout.org/PCB-Routing/
[18:48:16] <jepler> http://emergent.unpy.net/files/sandbox/pcb-gerber-pcb2gcode.png
moop: thanks for the link, but the reason I'm investigating these programs is because I would prefer to switch from eagle to Free software.
hm, it's not mirrored. I must be missing a flag to pcb2gcode
and the round parts are absolutely tiny lines, on the order of 1mil
I think there's a bitmap involved somewhere
I wish people would stop writing that
cradek: can heeks open ps or eps?
gbr, dxf, svg
ah, gerber I can make
[18:59:40] <jepler> http://emergent.unpy.net/files/sandbox/lll.group3.gbr
wow - that is a really small file
cradek: on the 308 it would not let me enable the drives with an alarm so the only thing I could figure out was pull the BRH to clear them
is there a simple way to invert the direction of the axis? then i press page-down my Z goes up ;)
elmo40_emc: invert in config -
I think there is at least two different ways
invert direction pin comes to mind
so i shouldnt edit the .ini file? just use step-conf again and invert that way?
elmo40_emc: just use pico open the file and add a '-' to the direction line
always a good thing to backup your files before editing too
jepler: Where did that drunk line come from?
so far 10.04 runs like a top :)
SOOOOOOOO much smoother and more precise then mach3 ever was. Way more configurable, too :)
Anybody know of a printer head that could be hooked onto a small CNC table?
I want to build one of these but I need one that is about 15-16" wide. I was thinking the best way would be to just find a printerhead and go from there. http://hackaday.com/2010/06/06/how-to-diydtg/
Birdman3131: The ONLY thing I could ever think of is ripping apart a inkjey printer somehow and using the print head in there
heeks can import the gerber files that pcb exports, and I think with a little work its pocketing operation can give me appropriate part programs for trace isolation
The only problem is that I am not sure what printer would be the easist to do given that the driver will probably need to be scrapped and redone.
jepler: have you seen this? https://sourceforge.net/projects/pcb2gcode/files/
elmo40: yes, but I was not thrilled with its output. When there are curved parts, it outputs tons of tiny lines. http://emergent.unpy.net/files/sandbox/pcb2gcode-zoomed.png
it must only convert by using X&Y
Birdman3131: parallax used to have an inkjet module, but it seems to have disappeared. For all the good it'll do, there is still a datasheet. http://www.parallax.com/dl/docs/prod/robo/InkjetKitDocs-v1.0.pdf
no R or I&J
jepler: did you read the wiki? maybe add this to the command: --max-deviation=0.005 --dpi=2000
jepler: That looks interesting but color is also needed.
[20:01:48] <elmo40> http://cpwebste.blogspot.com/
jepler wrote: "...I would prefer to switch from eagle to Free software." You have probably looked at the gEDA suite, what did you think of it?
If you haven't, there are 6 or 10 pieces to it available in Synaptic
led me to http://spritesmods.com/?art=inker
which seems very helpful.
hrmm, seems like these guys are jack-of-all-trades... but a master at NONE of them. Take a close look at the PCB outcome, very horrible lines. http://www.youtube.com/watch?v=1Dnw4xaMWTc
Then near the end that stepper is shaking up a storm. :-P
elmo40: thanks, I'll try that
KimK: yes, geda is what I'm looking at. I've looked at it a few times before and never gotten very far. now I think that all the parts of the process are probably doable, so it's just a matter of whether the annoyance of learning new tools is greater or less than the annoyance of installing the version of eagle that I bought a license to..
gschem + pcb + gerber-to-gcode will be a lot less integrated than eagle
celeron55_ is now known as celeron55
elmo40: I had specified --max-deviation=0.005 --dpi=2000

pretty much copied from the wiki
I see that it programs G54 P0.005 so emc is going to merge some of those straight segments when it actually mills the part
those little edges mean nothing. did you see the values? Y0.347625 to Y0.347875 is a difference of 0.00025" !
your machine is not even that accurate.
our $450,000 Mazak machines are not even that accurate.
in an ideal world those moves would be specified as (few) arcs instead of (many) lines
But..But....I gave it the numbers so it should follow them. ;)
Is there such a thing as drill bits but with "standard" sized shanks? Like an 'A' (0.234") size drill bit on a 1/4" shank ?
Jymmm: the only thing I've seen like that are tiny pcb type drills with 1/8 shanks
cradek: Yeah, that's the only thing I've see too, except those cheap hex ones for quick change.
Anyone have any ideas on how to read RPM from a Bosh Palm router like this: https://m21.hyte.de/wiki/SpindleMeter
also there are S&D drills made for using too big a drill in too small a drill chuck
usually those are over 3/8 though
cradek: Ah, yeah, don't need that big. Need to drill lots of straight pilot holes into MDF, just figured plunge router bearing are a lot better than my drill press
cradek: I need to drill on edge, not side.
Jymmm: doesnt your collet shrink to that size?
you could make a sleeve ;)
i have a 1/2" router and a 1/4" collet sleeve for it.
elmo40-emc: I have 1/4 3/8 and 1/2 collets
do you have access to a lathe? it would be easy to make a one-off sleeve.
then make an 'A' sleeve for the 1/2" collet. ;)
yeah what he says
cradek: no lathe, and no knowledge of using one if I did =)
figured out why i couldnt get the Z to move. the board (which was soldered by someone else) was not built correctly. They used the 4th axis to control the Z. Now everything is fine :)
*maybe* I can get away with using a rotobit, I'll have to check the size
what knowledge is required? add material, remove chuck key, grab tool, face-turn-bore. simple enough
elmo40-emc: Awesome! Can you get that into the mail by tomorrow?
i must have done something wrong with the gcode tool for inkscape. i tried installing it on my fresh 10.04 install. i get the menu item but nothing is under it.
Jymmm: address? i can if u want. i am in Canada... postage would be probably $2
plus $50,000 for cross-border duties (your feds are BROKE!)
elmo40-emc: No problem, I'll pay you $60,000 in JAMACIAN dollars
Connor: There's probably a plastic fan impeller on top of your Bosch router, maybe you can fit an optical pickup either interrupt-type or reflective-type there, and divide by n if needed?
KimK: My bosch router has the fan close to the collet, not the top
It's not very visable on the palm colt either
Also, DONT TAKE APART A BOSCH ROUTER, unless you have an instant replacement warranty on it =)
No way to put them back together right? P)
like I had when I took mine apart =)
Connor: Well, I was trying to remove the cord to run thru some energey chain, when I put it back together it didn't work for some reason, though I had an instnat replacment warranty so I didn't worry about it.
That's not cool
and I was being careful too, guess I loosened something up I wasn't suppose to. I didn't bother to look as to what/why, just replaced it
It might be possible to kludge in a speed pickup from the outside only, if you can see the edge of the fan blades going by a vent slot. Maybe paint one edge white and trigger on that? Hope you're not raising a lot of dust, though.
Looking at it.. Might be able to make a "disk" that can go just below the collect nut..
There is an area on the spindle you may be able to use an opticla tach
that tape thingy
looking at the buttom of the spindle, it has a shiney disk with 4 dents (1,3,6,12 o'clock), may for some sort of wrench... then a threaded area with about 1/2" or more.
What kind of end mill do you all use with these little Bosh routers?
Carbide on everything
Well, MDF, Plastic and thing sheet alumn (.040 - .060)
Connor: MDF.... CMT (brand) Spiral up cut
[20:53:11] <Jymmm> http://www.acetoolonline.com/CMT-191-008-11-1-4-UPCUT-SPIRAL-BIT-p/cmt-191.008.11.htm
Connor: I had suck luck with Freud brand, CMT are damn nice to work with.
okay, two flute spiral upcut
Was thinking of getting one of those anyway (Bosh brand which my Lowes carries)
Depending on the depth of cut you might want more flutes.
pretty much want upcut on anything.. right?
bits or router?
bits, Lowes carries Bosh brand bits.
Eh, I think they are rebrand, but not sure.
CMT brand are awesome
That page claims that the spiral flutes keep the edge in constant contact, but that is only true for a depth greater than half a spiral lead
andypugh: if you go too deep too many flutes will get clogged and break the tool.
2-flute for roughing, 4+ for smooth finish
The upcut helps eject the mdf dust
Possibly 4-flute for shallow grooves relative to tool diameter too.
use downcut if you need to have a clean surface without chipouts
in wood that is
when you rough you want to hog out as much as you can. you need the clearance between the flutes for the material to escape. if you are not removing much material then sure, 4-flutes would be stronger.
but then that means you are making a finish cut anyways ;)
I would love to be able to control the RPM via emc
elmo40: I am not thinking in terms of strength, but constant cutting force (and hence low vibration)
Well, you could rip out the pot and use EMC to controll from 8000 to 23000 RPM
but noe feedback as to TRUE rpm
Connor: Or use a radio-control servo motor to rotate the knob by friction...
(If you set up a PWM function right it will operate an RC servo)
I'm thinking.. maybe turn the pot all the way up. (fastest) and make some sort of AC controlled device (via PWM)
and add the RPM disk.
It's probably a Universal Motor, you can infer the speed with an inductive pickup on the power leads.
Connor: They may have changed since I bought mine, but this used to be Bosch, http://www.sears.com/shc/s/p_10153_12605_00928084000P?prdNo=2&blockNo=2&blockType=G2
Connor: I mention sears becasue you can buy that warranty I was talking about and replace it even at 4pm on a Sunday afternoon
That's the one I have. http://www.sears.com/shc/s/p_10153_12605_00927256000P?mv=rr
oh, that's more a trim router, isn't it?
Ahh.. not worried about that.. i can always do the thing were you go buy "another one", put the broken on in same package, and return.
Kinda, but, it's really nice..
it's 1HP, at under 6amps.
except it only take 1/4" shank
Right. and you can use collets for 1/8"
I have 1/4, 3/8, and 1/2 collets
My machine is small, on 18"x12"4.5" envelope
so is mine
just something to consider is all

Not I, but there are a lot of people here, tell us about it and maybe someone will have advice for you.
JT-Hardinge: what did you call those vibration dampeners again?
<pet peeve> It's "dampers" not "dampeners". Dampeners make things wet....
andypugh: Yours it Brit speak. primarily
no you are wrong dampers make things wet, dampeners dampen vibrations
www.dictionary.com (which is a US dictionary) disagrees.
see definition #3
<pet peeve> damn dampeners are dampeners that are not working, damp damn dampeners are dampeners that malfunction in large scale hydroelectric power plants
either way, I just need the common name for them
