[00:00:04] <archivist> spotted dick
[00:00:22] <Mjolinor> sympathy for you
[00:00:33] <Mjolinor> oh, right, the pudding you mean
[00:01:10] <archivist> toad in the hole
[00:02:28] <Mjolinor> Anyway what about the swedish
[00:02:34] <Mjolinor> they have really odd names for food
[00:02:45] <Mjolinor> and they eat really odd food too
[00:03:07] <Mjolinor> surstromming being a good example, stupid name and how the hell anyone eats it will never know
[00:03:49] <ssi> everything the swedish say sounds weird

[03:42:40] <oxiredo_ro> hello
[03:42:49] <oxiredo_ro> hello
[03:43:45] <oxiredo_ro> I want to start making a CNC machine ( i have no experience with this). where can i start this ?
[03:44:46] -!- Valen [Valen!~Valen@2001:44b8:3199:9100:21e:8cff:fe63:55df] has parted #linuxcnc
[03:44:52] <jdhnc> credit cards are a good way to start.
[03:45:15] <oxiredo_ro> hmm...ok
[03:46:24] <jdhnc> what do you want to make with it? What materials? How much room?
[03:48:34] <oxiredo_ro> I want to start with a small one/room.
[03:48:54] <jdhnc> mill? router? lathe? 3d-printer?
[03:49:34] <oxiredo_ro> I sow on youtube a 3d printer, so, a 3d printer
[03:49:45] <oxiredo_ro> i dont know what are the other
[03:51:41] <oxiredo_ro> I realy dont know anything about CNC
[03:53:47] <Tom_itx> want a kit or scratch build one?
[03:54:09] <Tom_itx> i think mendlemax is supposed to be a good one
[03:54:22] <Tom_itx> talk to maxbots in #seattlerobotics if you want
[03:58:29] <oxiredo_ro> tnx fro help, I need to study this more. and also the "credit card issue" :)
[03:59:19] <djdelorie> makerbot and printrbot are other kits you could investigate
[03:59:38] <oxiredo_ro> k, tnx
[04:00:34] <Tom_itx> i'm not into the reprap stuff, i just know maxbots
[04:00:45] <Tom_itx> and that he was working on a kit
[04:01:35] <oxiredo_ro> and how do I integrate those machne with a PC
[04:01:48] <oxiredo_ro> can i make it via microcpntrollers..?
[04:01:59] <oxiredo_ro> or dedicated cnc controllers ?
[04:02:07] -!- capricorn_one [capricorn_one!~raffi@zima.linwin.com] has joined #linuxcnc
[04:02:43] <Tom_itx> some of them use dedicated controllers
[04:02:56] <Tom_itx> like i said, i don't know alot about em
[04:03:05] <Tom_itx> i'd suggest you visit with him
[04:03:22] <Tom_itx> or join #reprap

[08:52:09] <mrsun> hmm this is strange
[08:52:58] <mrsun> when moving positive on my X axis i get exactly 1mm if i set linuxcnc to go 1mm, moving backwards, first step i get exactly 1mm, second time i get 0.95mm, next im back at the 0 mark (so it moves 1.05mm aparently) ... then it goes over again, this is ONLY in the negative direction
[08:53:01] <mrsun> wth is up with that? :/
[08:53:10] <mrsun> ive got 1/8 microstepping if im not mistaking
[08:53:36] <mrsun> that calculates to 0.00125mm/step so it cant be that it just craps on one step its a buttload of stepps it has to not do for that to happend ...

[09:04:13] <Mjolinor> thats my confusion
[09:04:53] <Mjolinor> as the letters are filled in when extruded I have to subtract them with the "cut one solid form the other"
[09:05:07] <Mjolinor> that works fine on the 9 but not on the 0 of the 10
[09:05:23] <Mjolinor> and why has hte 5 extruded as a shell and not a solid?

[14:57:33] <A2Sheds> whats the lowest cost power feed for a manual bridgeport?
[15:00:43] <jthornton> a milk shake can power mine for a while till I get tired
[15:04:23] <A2Sheds> jthornton, do you feEl like standing around someones garage for a few years? I'm pretty sure they can supply the milkshakes
[15:04:55] <jthornton> too busy standing around in my shop :)
[15:05:00] <A2Sheds> heh
[15:05:37] <jthornton> my guess is a used but good one would be the lowest cost
[15:06:11] <A2Sheds> I have an old Cincinnati vertical mill for sale, somebody asked about a power feed for the table
[15:07:07] <jthornton> Enco, Griz and other chinese importers would have the cheapest ones
[15:07:56] <A2Sheds> a shop near me was selling those, 75% came back for warranty issues
[15:08:19] <jthornton> the other 25% were shot on sight?
[15:08:24] -!- vladimirek has quit [Remote host closed the connection]
[15:08:25] <A2Sheds> hehe
[15:09:02] * jthornton heads back out to the shop
[15:23:31] <ssi> JT-Shop: in the shop yet? :D
[15:23:49] <JT-Shop> yep, draining the plasma tank :)
[15:24:03] <ssi> I played the power game last night
[15:24:15] <ssi> I was hesitant to use the VFD, so I tried to power it up using a static
[15:24:18] <JT-Shop> who won?
[15:24:23] <ssi> mostly the lathe
[15:24:30] <ssi> the static wouldn't kick on
[15:24:47] <ssi> so I grabbed a little 1hp 3ph motor that I have and tried to make a rotary converter
[15:24:56] <ssi> got that working
[15:25:02] <JT-Shop> cool
[15:25:14] <ssi> flip the breaker, motor comes on, turn on the master on the lathe, and I get a red light on the control, and nothing else
[15:25:20] <ssi> plus... smoke from a filter :D
[15:25:23] <ssi> even the rotary did it
[15:25:48] <ssi> meanwhile the static was on the wall clackin away sounding all unhappy
[15:25:54] <ssi> so I shut it back down and hooked it up with the VFD
[15:26:18] <ssi> same thing... only this time the filter that was smoking actually caught on shitting fire
[15:26:33] <ssi> so I removed all the filters out of the power enclosure
[15:26:43] <ssi> and realized that the interface encloseure was open, and there's an interlock
[15:26:46] <ssi> so I closed that and tried again
[15:26:49] <ssi> this time I got much more
[15:26:54] <JT-Shop> I did the same after smoking one or two
[15:27:08] <ssi> more lights on the control, control fans spinning
[15:27:13] <JT-Shop> cool
[15:27:14] <ssi> now it just sits there and blinks "COLLET OPEN" at me
[15:27:23] <ssi> I'm guessing it won't budge until I have air attached
[15:27:27] <JT-Shop> blink back
[15:27:47] <JT-Shop> yea, no air, no coolant, no no no and you don't run
[15:27:55] <ssi> coolant too?
[15:27:57] <ssi> how do it know? :(
[15:28:17] <JT-Shop> mine has a float switch in the coolant tank, and the oiler and and and
[15:28:22] <ssi> bluhhhh
[15:28:29] <ssi> what do you run for coolant in yours
[15:29:13] <JT-Shop> Valcool VPTech
[15:29:40] <ssi> oil based?
[15:30:08] <JT-Shop> water soluble looks like blue toilet water when fresh
[15:30:15] <ssi> ah ok
[15:30:28] <JT-Shop> only bad thing is it doesn't taste like beer
[15:30:33] <ssi> I was hoping to use straight oil based coolant,
[15:30:37] <ssi> but because of the capacity and the price
[15:30:40] <ssi> I may end up reneging on that
[15:30:53] <JT-Shop> I think cradek uses neat oil in his
[15:30:58] <ssi> neat oil?
[15:31:00] <ssi> is that an actual name?
[15:31:05] <ssi> or just a descriptive adjective :D
[15:31:14] <JT-Shop> you don't cut it with anything
[15:31:21] <ssi> Neatsfoot oil is a yellow oil rendered and purified from the shin bones and feet (but not the hooves) of cattle
[15:31:35] <JT-Shop> not the same thing lol
[15:31:37] <ssi> teheheheh
[15:31:48] <ssi> Neat cutting oils are fluids usually based on mineral oils and used for cutting without further dilution i.e. as supplied by the manufacturer
[15:32:01] <JT-Shop> so you just drip it onto the part as you cut instead of flooding
[15:32:15] <ssi> what do you usually cut oils with?
[15:32:31] <ssi> I use mobilmet out of a hand bottle, and I really like the stuff
[15:32:52] <JT-Shop> is it straight from the bottle?
[15:33:08] <ssi> the way I've been using it, yes
[15:33:12] <ssi> I put it in a little hand oil can
[15:33:17] <ssi> and squirt it directly on my parts
[15:33:26] <ssi> but it's pretty viscous for flood coolant
[15:34:48] <ssi> I mostly don't want water soluble coolant because I don't like the way it rots
[15:34:50] <JT-Shop> which mobilmet do you use
[15:34:51] <ssi> heh
[15:35:05] <ssi> I'll have to go check
[15:35:20] <JT-Shop> I see a bunch to choose from...
[15:36:36] <ssi> 426
[15:38:37] <JT-Shop> I think I'll get a gallon for the BP knee mill
[15:38:50] <ssi> I've been pretty happy with it so far
[15:38:53] <ssi> makes parting much easier
[15:40:00] <JT-Shop> cool, parting is a pain on the old Samson manual lathe
[15:40:12] <JT-Shop> I need a scatter shield for it...
[15:42:05] <JT-Shop> wonder if something like this http://www.mcmaster.com/#squirt-bottles/=glpxka would be better than a cheap leaking oil can
[15:42:22] <ssi> ok so...
[15:42:25] <ssi> oh jeez
[15:42:32] <JT-Shop> wow

[17:23:37] <psha> joe9: mdadm is in sbin

[17:23:52] <ssi> that explains that :D
[17:23:53] <psha> usually /sbin/mdadm
[17:24:21] <Mjolinor> is there a "usually" I generally find it pretty random :)
[17:24:34] <Mjolinor> it is always in the last palce you look that's for sure
[17:26:49] <ssi> /sbin, /usr/sbin, etc are typically binaries that only root is expected to ever use
[17:26:59] <ssi> so only root typically has them in path
[17:27:25] <ssi> if you're the kind of user that likes to do everything with sudo, you might consider putting them in path
[17:29:28] <joe9> in my case, I have a non-working installation on the disks (raid1). I do not know if aptitude looks at that to see if mdadm is installed.
[17:29:34] <joe9> but, I do not see mdadm binary in /
[17:30:22] <joe9> "a volume with software packages has been detected" it says, when I start using the livecd.
[17:30:42] <joe9> is it common? is it referring to the livecd volume or the volume in the disks.
[17:31:18] <joe9> when I try to partition the disks, it lists the "ext4, ext3 .. " filesystem, but not a raid-1 partition there.
[17:33:28] <psha> joe9: raid1 just looks like ordinary partition
[17:33:34] <psha> but with mdadm superblock in the end
[17:34:02] <joe9> oh, ok. but, if I partition the disk as ext4, it will not be a raid-1 disk anymore. correct?
[17:34:26] <joe9> psha: the raid-1 disks show up as "unknown filesystem" but, with the flags "boot, raid" setup
[17:35:52] <psha> it depends on your luck :)
[17:36:00] <psha> probably it won't kill superblock in the end

[21:36:09] -!- pcw has quit [Ping timeout: 252 seconds]
[21:36:47] <gene77> for a ball screw maybe
[21:37:44] <djdelorie> I mean, without considering friction. Just want to make sure the ratios aren't backwards or my math is missing a step
[21:39:30] <gene77> my math isn't as good as yours DJ. With a 425 on a 10 tpi acme, and a 17/42 gear down, I can hit 155 lbs on my z axis when the motor is tapped out
[21:40:12] <gene77> lots of friction in the acme
[21:40:29] <djdelorie> gear down increases torque to 1050, yes?
[21:41:18] <djdelorie> is that 425 oz-in?
[21:41:32] <djdelorie> and I think the diameter of the acme screw needs to be known too...
[21:42:45] <gene77> yes, but may not be getting full current, its an 8 wire motor, wired in series, and getting about 2.34 a phase, says 5 amps running unipolar
[21:42:49] <JT-Shop> gene77: IIRC for angular set the limits to some insane value for + and -
[21:43:19] <mrsun> archivist, but in one direction it works fine, 4 steps in one direction, each is exactly at 0, 4 steps in theo ther direction first is exactly spot on (have backlash compensation) then next is 0.95, next is 1.05, next is 0.95 .. all in the same direction, i do not change direction at any time
[21:44:30] <djdelorie> my screw rod is "local hardware store" so I probably have even more friction :-)
[21:44:34] <JT-Shop> djdelorie: are you calculating stepper torque?
[21:44:42] <archivist> mrsun, drunk thread on the screw
[21:44:53] <djdelorie> at the moment, I'm trying to figure out a realistic limit to winding current for my firmware
[21:44:57] <mrsun> archivist, heh ? :P
[21:44:58] <gene77> I was told that a 0 disables that, and its been zero zero for a long time John, years even. This however is the master-rt branch 2.60.something

[21:45:31] <archivist> mrsun, technical term for a bad helix on a thread
[21:45:36] <djdelorie> I mean, if I run all three motors at "peak current" at the same time, I'd need a 4 KWatt power supply...

[21:45:51] <mrsun> archivist, but shouldnt that show up in both directions?

[21:46:43] <JT-Shop> so just for shits and grins put a number in your limits and see if your A takes off
[21:46:44] <archivist> mrsun, I would expect so but depends on the error
[21:47:04] <mrsun> i was more thinking if its due to linuxcnc skipping some steps cause its "close enough" =)
[21:47:14] <djdelorie> I have 2 amps available, if I limit to 0.6 amps per motor, that's (in theory) still 30 oz-in per motor. Or I could limit to 2 amps per motor, and monitor the power supply volts as well
[21:47:25] <archivist> mrsun, that does not happen
[21:47:36] <mrsun> archivist, ok good i got that sorted atleast =)

[22:20:54] <djdelorie> archivist: I can imagine trying to "home" a lathe, and having it spin for minutes...
[22:22:25] <JT-Shop> ah sweet a loose wire
[22:22:43] <Tecan> why does hal have to be enabled ?
[22:24:07] <Tecan> i got a rt kernel without one for 11.04
[22:24:39] <Tecan> rtai is requiring it to compile the kernel modules
[22:30:18] <archivist> djdelorie, I have a slow rotary on the 5 axis and returning to the start point is "slow"
[22:31:03] <djdelorie> I meant, if it had to "unwind" a couple thousand rotations to "home" a rotary axis, that would be... less than useful.
[22:31:42] <archivist> currently a rotary axis can be like that
[22:31:55] <archivist> grmbl
[22:32:47] <gene77> grmbl is mild
[22:33:41] <archivist> now where are my bore gauges...even internal calipers

[23:11:02] <hatch789> what is the mdi command to zero the axis right where they are now?
[23:14:12] <GoSebGo> hatch789: i dont know off the top of my head, but i bet the answer is somewhere in this doc: http://www.linuxcnc.org/docs/2.5/html/gcode/coordinates.html

[23:16:14] <JT-Shop> hatch789: do you wish to set the machine origin or an offset?

[23:25:08] <hatch789> just to zero X&Y right where it is. not home them ...already homed
[23:25:50] <cradek> typically you'd use the Touch Off function, but you can do it in mdi as well; check section 3.2 in the link from Seb
[23:27:39] <JT-Shop> cradek: did you see ssi asking what cutting oil you used?
[23:27:48] <cradek> no
[23:28:01] <cradek> the stuff I have in the lathe I don't think is available anymore
[23:28:08] <cradek> it's some soybean-based thing
[23:28:22] <JT-Shop> I never could find it when you told me what it was
[23:28:35] <Tom_itx> whale blubber
[23:28:38] <cradek> yeah I think they're gone
[23:28:46] <cradek> I can't remember the name of it
[23:29:21] <JT-Shop> I did find some soy oil based stuff but by that time I had all ready gone with ValCool
[23:29:43] <Tom_itx> maybe for food processing equipment?
[23:30:14] <cradek> it smells kind of like french fries

[23:30:22] <cradek> very inoffensive smell
[23:31:07] <JT-Shop> maybe I got dyslexic and connected the wires backwards from the plasma tip voltage... I guess I'll take it back apart again :/
[23:31:40] <JT-Shop> too bad the ValCool doesn't taste like beer...
