[04:49:56] <Loetmichel> mornin'
[04:54:32] <MrSunshine> GOOOODMOOORNING GOOODMORNING! =)
[04:54:36] * MrSunshine hugs Loetmichel
[04:54:44] <MrSunshine> today is hugday in #linuxcnc :P
[04:56:02] * DJ9DJ keeps safe distance to MrSunshine
[04:56:16] * MrSunshine runs after DJ9DJ and gives him a hug also =)
[04:56:27] <MrSunshine> admit it, you need it =)
[04:56:30] <DJ9DJ> hrhr
[05:21:34] * alex_joni looks for #emc
[06:49:08] <Loetmichel> MrSunshine: Puaargh... that the job of my wife, not yours ;-)
[07:03:41] * Loetmichel is desperately trying to stay awake... slow day at the company... 3 hrs left...
[07:03:58] <Valen> go to sleep under a desk
[07:05:52] <Loetmichel> Valen: being the production manager that would stick out and be notiuces in an instandt ;-)
[07:05:56] <Loetmichel> -d
[07:06:10] <Valen> your bad at your job then ;-P
[07:06:30] <Loetmichel> ?
[07:06:52] <Valen> your sposed to be indespensible, but always busy somewhere else
[07:06:57] <Valen> like the golf course
[07:07:00] <Valen> or the beach ;->
[07:07:05] <Loetmichel> hrhr :-)
[07:07:46] <Loetmichel> i already had some "talk" with my boss for ircing while on work ;-)
[07:08:09] <Valen> well its obviously just using the open source support system right
[07:08:15] <Loetmichel> <- "what work? get orders, so i can do something!"
[07:08:21] <Valen> lol
[07:09:00] <Loetmichel> Valen: right, that would be a good reply ;-)
[07:29:31] <MrSunshine> leopfft =)
[07:29:35] <MrSunshine> Loetmichel, pfft
[10:50:38] <tjb1> Good news, T-Slots is sending out replacement extrusions
[10:51:42] <jdh> why?
[10:56:01] <tjb1> That one is bent, the other is gashed all over the place
[10:56:21] <tjb1> http://sphotos.xx.fbcdn.net/hphotos-ash3/557213_4007142532937_1214748650_n.jpg
[10:57:51] <jdh> bummer. Damaged in shipping?
[10:59:14] <tjb1> Not sure, the other 10ft(gashed) isnt bent
[10:59:24] <tjb1> It was shrink wrapped right to this one
[10:59:49] <tjb1> But all the gashes are anodized so it was bad right after they extruded it...
[11:05:04] <FinboySlick> tjb1: Still a bummer that you have to wait for new extrusions.
[11:05:15] <tjb1> Im in no hurry at the moment :)
[11:05:31] <tjb1> I havent worked in over a week so it looks like the leftover of my student loan is gonna finish this
[11:05:33] <FinboySlick> tjb1: Still have to make room for it? ;)
[11:05:56] <tjb1> I guess I can build one badass 3D printer :D
[11:06:43] <FinboySlick> tjb1: Heh, you sure wouldn't have to worry about one layer of your part not being set before you do the other layer.
[11:07:12] <tjb1> I dont know what to do with those extrusions
[11:07:34] <tjb1> That bend starts at 26.5" from the end
[11:07:39] <tjb1> So I have nearly 8ft of a good piece
[11:08:00] <FinboySlick> tjb1: You could try to straighten it I guess.
[11:08:16] <FinboySlick> Worse that'll happen is that it'll still be bent.
[11:08:20] <tjb1> I thought about that…my luck is that the t slots would collaspe or something
[11:08:37] <tjb1> I could make a small router :D
[11:08:55] <Loetmichel> re @ home
[11:11:32] <FinboySlick> tjb1: Hmmm, how about some other kind of tool? Bandsaw, things like that you might need.
[11:12:00] <tjb1> Im not sure about making a bandsaw
[11:12:14] <FinboySlick> Or one of those motorized hacksaws.
[11:14:52] <jdh> used 26's for $2k
[11:14:58] <jdh> <urk>
[11:18:14] <tjb1> And…big surprise, makerslide is out of stock
[11:22:24] <Jymmm> Based on this illustration, I wouldn't buy/use it. http://makerslide.com/images/ms_long.jpg
[11:24:16] <tjb1> Wow now....
[11:24:38] <tjb1> I was gonna use it for a 3D printer Jymmm
[11:24:56] <tjb1> Boston Gear charges $109.54 for a 6ft piece of 20 PA, 20 Pitch rack...
[11:25:20] <tjb1> I can get 5 piece of that shipped for $254 from Moore Gear
[11:25:50] <tjb1> Jymmm: http://www.buildlog.net/blog/wp-content/uploads/2012/02/quantum_render_01.jpg
[11:25:54] <Jymmm> a 3d printer has no side force, you dont need anything that fancy
[11:26:35] <tjb1> Its only $0.011 an inch
[11:27:42] <tjb1> Sorry $0.011 a MM
[11:28:23] <tjb1> $6.69 for a 2ft piece
[11:32:24] <tjb1> But I keep checking randomly and I have only seen it in stock one time
[12:10:25] <peeps> anyone here dealt with 3d scanning? what do you recommend?
[12:10:41] <IchGuckLive> 10Mw Read
[12:10:48] <IchGuckLive> Miliwatt
[12:11:12] <IchGuckLive> peeps: object size
[12:11:53] <IchGuckLive> Art or construction part peeps
[12:12:03] <peeps> construction part i suppose
[12:12:34] <IchGuckLive> for construction part i adwise probing
[12:12:59] <IchGuckLive> or simple gimp to incjet to pycam
[12:13:54] <IchGuckLive> homeuse -> http://www.david-laserscanner.com/
[12:14:06] <frallzor> tried that, not impressed
[12:14:30] <peeps> frallzor, what didn't you like?
[12:14:37] <frallzor> the results
[12:14:38] <IchGuckLive> it is as it is free
[12:15:47] <frallzor> pretty much used the starter kit
[12:15:50] <IchGuckLive> peeps: do you got a part eyample
[12:16:43] <IchGuckLive> example
[12:20:11] <peeps> someone else was asking me about it, i'm not sure what objects exactly, but they work with automotive suspension parts mostly
[12:20:52] <IchGuckLive> then its worth to get a profasional involved
[12:21:01] <IchGuckLive> or even reconstruct
[12:22:04] <FinboySlick> if you're decent enough with CAD, it's often faster to just re-model the part than to scan it.
[12:22:22] <peeps> how does the probing work? like a probe toolhead on a mill? or an arm? is there any low cost arm that does absolute positioning, and you just manually move it around to the points?
[12:22:55] <FinboySlick> peeps: This is not an area where low cost is very frequent.
[12:23:47] <FinboySlick> peeps: Another thing is that if you need to modify a scanned model, you're SOL beyond just scaling it up or down.
[12:25:49] <Loetmichel> hmmm
[12:25:57] <Loetmichel> i want to have a 3d measuring arm
[12:26:18] <FinboySlick> For measuring I can definitely see usefulness.
[12:26:29] <Loetmichel> the problem with remodeling is the lack of measurements possible on the "original" part
[12:26:59] <Loetmichel> how do you measure threads drilled into a freeform surface for example?
[12:27:09] <FinboySlick> Loetmichel: Yeah, but it's easy to tweak to size in CAD.
[12:27:29] <FinboySlick> If your scan isn't accurate, forget tweaking, you have to re-scan.
[12:27:41] <Loetmichel> right
[12:28:13] <Loetmichel> or convert the point cloud to beziers and hope for a cad which can simplify the .stl
[12:28:26] <FinboySlick> For very curvy things I can definitely see a point.
[12:29:01] <FinboySlick> But most of the mechanical bits don't typically have a lot of complicated curved surfaces.
[12:31:43] <Loetmichel> FinboySlick: i actually had to design and build a frame for holding an air filter into the front of a dell server
[12:32:33] <Loetmichel> finally made a cardboard template and cut it 'til it fits, then get the steel "mesh" and cut it after the flatened cardboard
[12:33:00] <Loetmichel> would be SO much simpler if i had a measuring machine to get the awkward corners of the front frame
[12:35:15] <Loetmichel> http://ma.wishmesh.com/2011/03/dell-is-trying-to-save-trees-and-front-bezel-for-dell-poweredge-r510-server-arrives/05-dell-poweredge-r510-front-bezel-closeup/
[12:35:17] <Loetmichel> this one
[12:35:56] <Loetmichel> http://ma.wishmesh.com/2011/03/dell-is-trying-to-save-trees-and-front-bezel-for-dell-poweredge-r510-server-arrives/01-two-front-bezel-boxes/
[12:36:06] <Loetmichel> wasnt an easy job
[12:36:44] <syyl> i bet its very fast measured with a height gauge and a surface plate...
[12:37:33] <frallzor> http://img442.imageshack.us/img442/6204/img4121lr.jpg time for evolution
[12:37:36] <syyl> (been there, done that, for prototyping work..)
[12:40:06] <evil666> hi, i was compiling linuxcnc, encountered this "checking libgl1-mesa-dri workaround... test for libgl1-mesa-dri workaround failed, please file a bug" any ideas how to proceed?
[12:47:56] <FinboySlick> evil666: Only thing that comes to mind is that it might not like your version of mesa.
[12:48:10] <FinboySlick> evil666: But that's hardly helpful.
[12:48:34] <evil666> what should i do?
[12:48:40] <Loetmichel> syyl: the problem: i had needed the INNER form for the steel mesh, obviously
[12:49:34] <FinboySlick> Loetmichel: But they all looked like straight edges and arcs.
[12:49:51] <syyl> put a dial indicator with a long stylus on front of the height gauge and you are in buisness...
[12:50:01] <syyl> cant shock me with that :P
[12:50:49] <FinboySlick> It's also a pretty good use case for a touch probe.
[12:51:06] <Loetmichel> right, but i have none of this in the company
[12:51:13] <syyl> that converts your milling machine in a lowcost measuring machine ;)
[12:51:17] <FinboySlick> Loetmichel: Demand more tools.
[12:51:20] <Loetmichel> the only CNC mill i use in the company is my private one
[12:51:42] <Loetmichel> FinboySlick: i chan demand all that i want, dont mean i get any
[12:51:56] <Loetmichel> i am peading since 3 years to buy a cheap cnc mill
[12:51:58] <FinboySlick> Go on strike! ;)
[12:52:01] <Loetmichel> ... nothin happens
[12:52:14] <Loetmichel> "when we have enough money...."
[12:52:19] <Loetmichel> pleading
[12:52:36] <Loetmichel> and 5kEur isnt THAT much for a company...
[12:52:37] <FinboySlick> Build yourself a router, then you can cut a super nice striking sign...
[12:52:50] <Loetmichel> FinboySlick: i HAVE a CNC mill
[12:52:52] <FinboySlick> Walk around the parking lot.
[12:53:05] <Loetmichel> and using it for the company... and want that to stop
[12:53:08] <FinboySlick> Yeah, but unless it has a pretty good work area, nobody will notice the sign.
[12:53:11] <Loetmichel> ... besides its to small ;-)
[12:54:22] <Loetmichel> i am pushing my boss to buy one of these: http://www.team-haase.de/maschinen/al-serie
[12:54:28] <Loetmichel> the AL1065
[12:54:41] <Loetmichel> and i will get one... some time...
[12:54:43] <Loetmichel> +s
[13:10:41] <FinboySlick> Loetmichel: Why go for the little thing when you could have the FE 2015?
[13:16:30] <IchGuckLive> Loetmichel: for this price you can build a better on Minitec components and with 8Nm steppers
[13:16:44] <IchGuckLive> also big Drivewr stages
[13:17:54] <IchGuckLive> http://www.minitec.de/de//Web/produkte/Components/linear_system.php
[13:18:07] <IchGuckLive> Loetmichel: this is 45min to drive from you
[13:18:30] <Loetmichel> IchGuckLive: i dont WANT to build a machine for the company
[13:18:52] <Loetmichel> i want support/service payed by the boss, not done by me in my free time!
[13:18:55] <IchGuckLive> they got rerady made components yust screw them together
[13:19:42] <IchGuckLive> i had the "Vertreter" here on Thuseday with his nice backage
[13:19:51] <Loetmichel> as i said: i dont want to be responsible for service
[13:19:54] <IchGuckLive> it is expensive but it is worth all
[13:20:35] <Loetmichel> FinboySlick: the machine cant really be bigger: not more room in the companys workshop ;-)
[13:21:15] <andypugh> My not-quite-girlfriend works for a company that makes linear bearings. Possibly rather expensive ones, though. http://www.mahr.de/index.php?NodeID=29
[13:21:35] <andypugh> Very pretty. (both her and the bearings)
[13:22:01] <IchGuckLive> im off BY
[13:22:29] <Loetmichel> andypugh: mahr is well known
[13:22:31] <Gevallen_Engel> what should you use to oil up rails anyways?
[13:22:46] <Loetmichel> but not really in my price range ;-)
[13:22:51] <IchGuckLive> andypugh: im living 5Km away from them can take parts by bicycle
[13:23:03] <andypugh> Gottingen?
[13:23:13] <IchGuckLive> no minitec Ramstein
[13:23:26] <IchGuckLive> not mare
[13:23:32] <andypugh> I thought Ramstein was a band?
[13:23:33] <IchGuckLive> mahr
[13:23:43] <IchGuckLive> B) O.O Tschüss
[13:24:09] <Loetmichel> andypugh: more like a american army support point with some villagers around ;-)
[13:24:32] <FinboySlick> Loetmichel: Demand a bigger workshop! You guys can't bail out the EU if you stick to small shops.
[13:25:10] <Loetmichel> FinboySlick: my company makes computers in shielded and rugged
[13:25:46] <Loetmichel> the workshop is more or less for prototypes, the series is produced outside by dedicated sheet metal companies
[13:25:57] <Loetmichel> s/is /are
[13:26:17] <Loetmichel> so the metal workshop in the company is only for one person: me ;-)
[13:26:20] <FinboySlick> Loetmichel: So? Now you can make prototype shielded and rugged vehicles..
[13:27:46] <Loetmichel> FinboySlick: you think to big ;-)
[13:28:21] <Loetmichel> i make boxes for notebook SMPS or a casing for a laser prionters PCB and such stuff
[13:29:05] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13367 <- something like this
[13:29:08] <FinboySlick> Loetmichel: The money is in arms races. What you should do is sell sniffing devices that can see through your shielding to your customer's enemies.
[13:29:15] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13376
[13:29:20] <andypugh> Are laser pointers really subject to Tempest attacks?
[13:29:41] <Loetmichel> PRINTERS
[13:29:45] <Loetmichel> yes
[13:30:58] <Loetmichel> i've seen how our engineer had displaed the printed data of a LJ1200 from about 100m ditance
[13:31:01] <Loetmichel> distance
[13:31:11] <andypugh> Yes, I can imagine that you can pick up the raster modulation of a laser printer. They should use dot matrix instead.
[13:31:45] <Loetmichel> also monitors
[13:31:53] <Loetmichel> even TFT ones
[13:32:24] <Loetmichel> andypugh: actually we have a matrix rinter in portfolio.
[13:32:58] <Loetmichel> but more because it is capable of operating with 30G shocks, 100%RH and from -20°c to +55°c
[13:33:08] <Loetmichel> not because its shielded ;-)
[13:34:00] <andypugh> I am pretty sure I don't function at +55
[13:35:05] <Loetmichel> HRHR
[13:35:18] <Loetmichel> as a soldier you would have to ;-)
[13:39:14] <andypugh> One of many reasons I am not
[13:40:51] <FinboySlick> Hehe, one of our customers has been breaking into our transmission tower cabinets and stealing parts... Though not parts that would affect his service.
[13:41:09] <FinboySlick> Yesterday, they stole a managed switch and hooked it to their network...
[13:41:15] <FinboySlick> The switch called home.
[13:41:18] <FinboySlick> We called the cops.
[13:41:21] <andypugh> <giggle>
[13:41:36] <Loetmichel> *snicker*
[13:42:18] <andypugh> Did you see the ones about the guy who stole an iphone then uploaded loads of pictures of himself (including name badge) to the owners iCloud account?
[13:42:18] <FinboySlick> We're the only internet provider they have access to... Talk about sawing off the branch you're sitting on.
[13:42:33] <FinboySlick> Yeah. That's what it reminded me of.
[13:42:59] <Loetmichel> ... not knowing the icloud function i presume?
[13:43:22] <ctjctj> Is there anyway to have axis run an outside program (process) when it completes a job? I want to know when my remote axis completes a job.
[13:43:36] <Loetmichel> as in "every photo taken gets autmatically uploaded tho the icloud without notify on the phone"
[13:46:03] <Loetmichel> ctjctj: put a M100-M199 call at the end of your gcode, just before the M30?
[13:46:15] <Loetmichel> and write the according script
[13:46:53] <ctjctj> I'll look up the M100-M199 codes. thanks
[13:52:23] <ctjctj> Loetmichel: thank you, that is exactly what I was looking for.
[13:52:58] <Loetmichel> de nada
[14:14:26] <andypugh> Flexy-conduit arrived. https://picasaweb.google.com/108164504656404380542/CNCUnsorted#5761762994234565506
[14:15:24] <FinboySlick> andypugh: Artistic picture...
[14:16:02] <FinboySlick> Dunno if it's a mix of the colours or what, but it kind of strikes me.
[14:17:16] <andypugh> You are wwelcome to the carpet, just take it away.
[14:18:06] <andypugh> I am trying to figure out how best to make a 90-degree elbow for it.
[14:18:45] <andypugh> I have a half-baked plan I might try.
[14:47:06] <archivist> you want to run the undergrounds wiring in that? seems a bit bit :)
[14:47:37] <andypugh> No, it's for the run from the mill to the controller.
[14:48:07] <andypugh> There is rather a big bundle of cables, and also some connectors I would prefer to leave on.
[15:31:00] <MrSunshine> hmm, how sensetive is variable frequency drives on ripple on the analog frequency ref ?
[15:35:24] <taiden> how is everyone doing after having a fifth on the fourth?
[15:40:58] <Connor> andypugh: I found a 3' bore by 1" stroke 3 cylinder unit that should work good for a power draw bar..
[15:41:11] <andypugh> Where?
[15:41:20] <Connor> Well.. on ebay of course. :)
[15:41:23] <andypugh> Sounds too ideal :-)
[15:41:41] <Connor> Fabco MP model.
[15:41:58] <andypugh> Link?
[15:42:17] <Connor> Crap. It sold. :(
[15:42:35] <andypugh> I thought you meant you had bought it?
[15:42:43] <Connor> Oh. No. not yet.
[15:44:29] <andypugh> I see one for $200
[15:44:37] <Connor> This was for 107.00
[15:46:09] <Connor> Should have got it then.. 2.5" Might work...
[15:46:16] <andypugh> 1/5" for $89, but that is likely to be too small
[15:46:47] <andypugh> I still say make your own. You can then use a "pinch" design to give your spindle bearings an easier life.
[15:46:49] <Connor> 1 5/8" Yea. too small.. the 2 1/2" would be good.
[15:46:57] <Connor> That's the plan.
[15:47:27] <andypugh> 2.5" x 1/2" is what I meant to type
[15:48:03] <andypugh> I was designing it in my head as I rode home today. I reckon you could screw the sections together.
[15:48:18] <andypugh> Does your lathe do CNC threading?
[15:48:34] <Tom_itx> give us a nice solidworks picture of it
[15:48:35] <Tom_itx> :)
[15:48:36] <Connor> My mini lathe can thread.. but it's not CNC.
[15:48:51] <Connor> I can mount a 4" chuck on the mill and use it as a lathe..
[15:49:24] <Tom_itx> i should make an A axis that would use my lathe chuck
[15:49:37] <Connor> 2.5" looks like it would yeild around 1888lbs @ 130PSI
[15:50:36] <jdh> how about at 4000psi
[15:50:52] <Connor> jdh WHY on earth would I do that? :)
[15:51:13] <Connor> jdh: I do need to figure out a regulator for my scuba tanks..
[15:51:23] <jdh> I have about 3500ft^3 of 'air' at 4000psi
[15:51:58] <Connor> I have a OLD regulator that probably could be used.. I think it's too old to use for Scuba now...
[15:52:06] <jdh> craiglist a cheap reg, put an OPV on it, cut off a LP hose and put a barb/NPT on it
[15:52:12] <Connor> not to mention, I've not been diving in over 15 years.
[15:52:22] <jdh> bummer
[15:52:45] <jdh> stop by rheas diving in maryville
[15:52:59] <Connor> Yea.
[15:53:12] <Connor> this thing was like 15 years old when I got it used.
[15:53:31] <Connor> easy. I've never had it serviced.
[15:54:26] <Connor> How much pressure does the LP hose have ?
[15:54:56] <jdh> 145ish
[15:55:01] <Connor> The only HP hose is the one with the Gauge right ?
[15:55:22] <Connor> The main line, the Backup and the BC are all LP
[15:55:25] <jdh> you can adjust the LP (MP really) down to 100 or so
[15:56:14] <Connor> 140PSi with the 2.5" would get me around 2033Lbs. :)
[15:56:28] <Tom_itx> how much do you need?
[15:56:48] <jdh> most non-ancient regs can be run up to 165 or so before they run out of spring
[15:57:04] <Connor> Depends on how tight you tighten up the belleville washers.
[15:57:23] <Tom_itx> you get that much force on a retention knob it may well pop off
[15:57:42] <Jymmm> That can't be right.... 1.3mm thick http://www.harborfreight.com/pack-of-50-trash-bags-55-gallon-90519.html
[15:57:59] <Tom_itx> probably mil not mm
[15:58:01] <jdh> probably 1.3 mil
[15:58:19] <Jymmm> jdh: they say "extra thick"
[15:58:24] <Connor> Tom_itx: Retention knob? I.E. top hat?
[15:58:34] <Connor> It'll be a pinch type.
[15:58:35] <Jymmm> 1.3mil would be extra thin
[15:59:02] <Tom_itx> Connor, i dunno how you are designing it but our holders had retention knobs
[15:59:20] <Jymmm> 1.3 mil would be like produce bags, wouldn't it?
[15:59:30] <Connor> Tormach TTS.
[15:59:43] <Connor> Has a modified 3/4 R8 Collet.
[16:00:06] <jdh> what do you pinch?
[16:00:30] <Connor> top of the draw bar.. and a "top hat" that's threaded onto the spindle.
[16:00:51] <Connor> so, it doesn't put pressure on the spindle itself.
[16:00:59] <Connor> the washers are between.
[16:01:11] <jdh> you just push down on the drawbar, opposing the washers?
[16:01:54] <Connor> You push down onto of drawbar.. hole mount assembly raises. I plate UNDER the washers makes contact with a tophat..
[16:02:06] <Connor> and it squeezes the washers together.
[16:02:41] <Jymmm> Hmmmm interesting http://www.webstaurantstore.com/guide/61/trash-can-liner-buying-guide.html
[16:05:00] <Jymmm> the HF bags do say LDPE
[16:07:48] <jdh> http://www.ebay.com/itm/110667207507
[16:07:50] <jdh> what does that do?
[16:08:42] <Jymmm> change tooling at the push of a button jdh
[16:09:05] <Loetmichel> jdh: looks like a drawbar for the tool holder driven by an air wrench
[16:09:13] <Loetmichel> for the lazy of us ;-)
[16:16:45] <jdh> oh, it's just an impact wrench... nevermind
[16:30:41] <mcenter> What is a good way to use linuxcnc with only two axis?
[16:31:55] <mcenter> I have two servos, mesa 5i25 + 7i77
[16:32:20] <mcenter> Baldor 26M +-10V drives
[16:33:26] <mcenter> I edited a HAL for two servos, but AXIS doesn't seem to like it.
[16:33:40] <Jymmm> cnc chop saw
[16:35:03] <mcenter> No, it is a gantry. I plan to add a third axis sometime later, but I need to get two axis going pretty soon.
[16:37:09] <JT-Shop-> mcenter: can you describe "Axis doesn't seem to like it" a bit more specific?
[16:38:36] <mcenter> When I start linuxcnc, the AXIS display complains there is no Z axis, and my system locks up.
[16:41:07] <JT-Shop-> do you know where your ini file is?
[16:41:28] <Nick001-Shop> In the ini file axis= 1 more than what you have ---2axis is 3 axis in ini
[16:41:45] <JT-Shop-> I suspect that is not the problem
[16:42:38] <mcenter> @JT - I have it in ~/linuxcnc/config.
[16:42:52] <Nick001-Shop> Coordinates = x z or xy
[16:43:33] <JT-Shop-> open it up and in the [DISPLAY] section put OPEN_FILE = ""
[16:43:40] <mcenter> @Nick - xy
[16:44:12] <JT-Shop-> mcenter: the splash screen is 3 axis so do the above and it won't load it
[16:44:44] <Jymmm> This is IRC, no @ needed
[16:44:53] <Nick001-Shop> also have to comment out unused axes in servo and other files in your config directory
[16:45:39] <Nick001-Shop> that's what I had to do to get 2 axis lathe to work in axis
[16:48:44] <mcenter> Thanks. I think I'll meander through my pasture to my shop (too far for wifi) and try.
[16:49:01] <JT-Shop-> ok when you wander back let us know
[16:49:25] <mcenter> Is it supposed to cool down next week in Poplar Bluff?
[16:49:31] <Jymmm> And avoid the meadow muffins along the way
[16:51:56] <JT-Shop-> cool for an arab maybe
[16:52:19] <Jymmm> Heh, a tent with attached garage http://www.rei.com/product/830975/big-agnes-wyoming-trail-sl2-tent
[16:52:24] <JT-Shop-> http://forecast.weather.gov/MapClick.php?CityName=Poplar+Bluff&state=MO&site=PAH&lat=36.7639&lon=-90.4072
[16:56:18] <andypugh> Connor: Tom_itx: http://imagebin.org/219613
[16:57:36] <andypugh> (You wouldn't have the top hole, that was just so I could use 4 identical parts)
[16:58:28] <Jymmm> what is it?
[16:58:44] <andypugh> Triple pneumatic cylinder
[16:58:50] <Jymmm> ah
[16:59:40] <andypugh> modular, screwed together
[17:06:05] <Jymmm> JT-Shop-: Mechanically speaking... In this video I see 1: a rotary cutter moving in and out, and 2) a clamp grabbing the card once finished winding. What are typically used for those motions? Just bronze bushing for the in and out? What about the clam shell action?
[17:06:08] <Jymmm> http://www.youtube.com/watch?v=XURVzKNXIdA
[17:08:37] <DJ9DJ> gn8
[17:10:26] <andypugh> It's hard to imagine there was a market for more than that one.
[17:10:26] <JT-Shop-> linear bearings
[17:11:01] <Jymmm> JT-Shop-: and the clamshell clamp?
[17:11:27] <JT-Shop-> looks to all be using linear bearings
[17:11:44] <andypugh> <Sulks at Tom_itx demanding a 3D model then not even looking at it>
[17:11:48] <Jymmm> Those "C" shape ones?
[17:12:12] <JT-Shop-> you don't make something like that with skate wheel bearings and plain bearings
[17:12:36] <andypugh> You are going to be charging 20k at least, too.
[17:13:05] <andypugh> So, what's the payback volume on $20k worth of sample cards?
[17:13:50] <Jymmm> andypugh: IT's for the textile industries, so seeing "fashion" changes each season, myabe a lot
[17:15:14] <andypugh> My point is that to pay for itself the machine has to make many tens of thousands of items without breaking down.
[17:15:23] <JT-Shop-> seems they had a bit of configuration problems that was fixed with some tape on the plexiglas
[17:16:02] <Jymmm> JT-Shop-: No, I don't need exactly that. What I need is embroidery yarn winder, but I can't find video of one yet... http://www.colinharbut.com/crafts/Creativity-Street-Embroidery-Floss-Set.jpg
[17:16:25] <mcenter> Axis display no longer complains about Z axis. But, it still locks up the computer. All I can do is move a mouse icon around.
[17:17:32] <andypugh> mcenter: Could be an OpenGL problem. What happens if you try the tklinuxcnc GUI instead? (just one change to the INI file)
[17:17:44] <JT-Shop-> so we fixed one issue and have one more to go
[17:17:58] <JT-Shop-> Andy types fast LOL
[17:22:46] <tjb1> Hardibacker sucks.
[17:28:53] <r00t4rd3d> concrete board?
[17:29:16] <r00t4rd3d> anyone use joy2key ?
[17:33:30] <Tom_itx> sorry andypugh i was away
[17:33:51] <mcenter> I'll try tklinuxcnc after supper.
[17:34:24] <tjb1> Yes r00t4rd3d, its a brand of it, not really concrete though...
[17:34:39] <tjb1> 60 screws in a 3'x5' sheet plus 1/4" thinset underneath
[17:36:13] <Tom_itx> andypugh i was more curious how the pull thru the collet tube worked
[17:37:01] <WillenCMD> does anyone know what the native units for stepgen is or does it matter, more specifically its use with hal outside of linuxcnc
[17:39:50] <andypugh> Tom_itx: It's possibly a bit clearer in the complete assembly picture: https://picasaweb.google.com/108164504656404380542/CNCUnsorted#5501336824053407474
[17:40:11] <andypugh> WillenCMD: Native units are "steps" :-)
[17:40:25] <JT-Shop-> WillenCMD: http://linuxcnc.org/docs/html/man/man9/stepgen.9.html
[17:41:06] <Tom_itx> andypugh why is a 3 stage cylinder needed and what exactly does one do?
[17:41:22] <Tom_itx> i get that it increases the pressure but how?
[17:41:37] <r00t4rd3d> got my new railz today
[17:41:39] <JT-Shop-> more effective area for the air to push against
[17:41:47] <andypugh> Tom_itx: It doesn't increase the pressure, it is just three pistons acting on one rod
[17:41:49] <jdh> I was going to get a joystick for jogging but ordered a contour? jog shuttle thing instead
[17:42:13] <andypugh> jdh: There is a special driver for that, because it is strange.
[17:42:14] <r00t4rd3d> i got a usb classic nintendo controller i want to use
[17:42:24] <alex4nder> nice
[17:42:36] <r00t4rd3d> http://www.ebay.com/itm/400304560914?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
[17:42:40] <alex4nder> r00t4rd3d: I have my PS3 controller working inside X, without joy2key
[17:42:42] <r00t4rd3d> 10.99
[17:43:02] <r00t4rd3d> alex4nder, can you control your axis with it?
[17:43:16] <Tom_itx> andypugh did you make your pull to fit an industry standard retention knob or did you make your own?
[17:43:37] <jdh> yeah, looks nifty for $38 shipped
[17:43:40] <andypugh> Industry standard knob
[17:44:09] <jdh> saw some cnc company selling them for $300
[17:44:14] <alex4nder> r00t4rd3d: yes
[17:44:34] <andypugh> jdh: I think Tormach sell them as a controller
[17:44:35] <alex4nder> r00t4rd3d: http://www.youtube.com/watch?v=3gODZJ_gBBA
[17:45:13] <r00t4rd3d> https://plus.google.com/photos/108164504656404380542/albums/5747722155741347649/5741409470138424130?banner=pwa
[17:45:22] <r00t4rd3d> andypugh, is that your girl?
[17:45:50] <andypugh> No, neither of them.
[17:46:40] <andypugh> Shuttle jogger with Tormach branding: http://www.tormach.com/store/index.php?app=ecom&ns=prodshow&ref=30616
[17:46:48] <r00t4rd3d> my joystick works in ubuntu fine, i just cant get it to control my axis
[17:46:58] <r00t4rd3d> is a ps3 controller usb?
[17:47:01] <alex4nder> yes
[17:47:25] <r00t4rd3d> I didnt install the Hal stuff either when i ran stepconf, should I ?
[17:47:38] <jdh> I watched a bunch of tormach videos yestetday and almost wanted one.
[17:47:41] <r00t4rd3d> and that guy says he used hal_input what ever that is
[17:48:35] <alex4nder> r00t4rd3d: the easiest way to make this work is to have your joystick send keyboard events inside X
[17:49:00] <r00t4rd3d> I know, but how are you doing it without joy2key or some other app?
[17:49:51] <andypugh> It's _much_ better to use hal_input and connect the controller into the HAL layer
[17:49:55] <alex4nder> X has a joystick driver; just configure it to do the right thing
[17:50:01] <alex4nder> andypugh: much?
[17:50:05] <andypugh> Yes
[17:50:16] <r00t4rd3d> how do i do that?
[17:50:23] <andypugh> For example, you get analog jogging.
[17:50:29] <r00t4rd3d> i know nothing of hal
[17:50:29] <alex4nder> andypugh: why is a button press from the keyboard much worse than one from the joystick?
[17:50:43] <alex4nder> oh, I have that with hal, I almost never use it.
[17:50:51] <andypugh> PS3 controllers have analog joysticks
[17:50:56] <alex4nder> no shit?
[17:51:03] <alex4nder> they also have analog buttons. ;)
[17:51:28] <andypugh> You lose the analogue part with keyboard emulation.
[17:51:34] <r00t4rd3d> analog buttons
[17:51:36] <andypugh> Instructions here: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Simple_Remote_Pendant
[17:51:46] <r00t4rd3d> anal og butt ons
[17:51:54] <alex4nder> yes, PS3 buttons have pressure sensing
[17:51:56] <alex4nder> it works in linux
[17:52:21] <alex4nder> I just don't agree that it's "much" better to use HAL, I set up analog sticks with HAL and almost never use it.
[17:52:39] * alex4nder shrugs.
[17:54:04] <andypugh> It may be a little more reliable, as the driver goes into the realtime layer by a less circuitous route. Relying on a GUI to service button actions isn't ideal.
[17:55:43] <jdh> vs axis jog crashing the spindle in the table
[17:56:11] <alex4nder> anyone can crash the spindle into the table
[17:57:11] <WillenCMD> i found a real easy way to implement jogging using a gui
[17:57:13] <jdh> wasnt that your axis bug discovery?
[17:57:39] <alex4nder> you mean software has bugs?
[17:57:48] <alex4nder> that's crazy talk.
[17:57:52] <Tom_itx> no just features
[17:57:55] <r00t4rd3d> YOU CRAZY
[17:58:13] <r00t4rd3d> sucks i just got my machine all built now i am going to tear it all back apart
[17:58:36] <jdh> its good for you.
[17:58:49] <Tom_itx> if it keeps getting better stop whining
[18:02:21] <JT-Shop-> WillenCMD: do tell
[18:03:11] <WillenCMD> i used threading timeout's to a function ever millisecond
[18:03:35] <WillenCMD> it advances a hal pin by the feed rate converted to milliseconds
[18:04:01] <WillenCMD> if it gets ahaed of the position its not a problem
[18:04:30] <WillenCMD> on button release it reads the position-fb and re-sets the position command to the current position
[18:05:33] <WillenCMD> and i also have a pulse being sent from the gui to hal watchdog, if the gui stops responding the watchdog will through the estop
[18:07:44] <WillenCMD> i also have a really nice num_pad module for gladevcp will be adding, its a touchscreen keyboard
[18:10:23] <andypugh> I think it is definitely worth writing your system up for the Wiki. It might even be worth thinking about adding it to the example configs (If folk are unaware, it is a single-purpose Glade Gui which uses only Glade and HAL, no motmod, no LinuxCNC gui, no G-code interpreter.
[18:11:40] <WillenCMD> i will definetly be adding it, as i look for feedback and code tweaks
[18:12:31] <WillenCMD> as of right now its 4000 lines of code
[18:13:02] <WillenCMD> not all in one module though, i have made seperate modules in case people would like to use them in a gui
[18:13:08] <WillenCMD> such as the num_pad
[18:13:25] <WillenCMD> the motion_controller is its own module
[18:36:58] <JT-Shop> YEA! high for Monday only 89F
[18:40:25] <jdh> 94f here. Im sitting in the sun at my kids swim meet.
[18:41:06] <Jymmm> jdh: You're just sadistic is all
[18:42:56] <jdh> I havent even seen my mill or router for a week due to heat.
[18:43:51] <Jymmm> jdh: Because you're giving yourself heat stroke from sitting in the sun in 94F weather!
[18:44:40] <jdh> because my garage is miseably hor and humid
[18:45:12] <JT-Shop> I really should quit welding in sandels ...
[18:45:56] <jdh> heh.interesting burn pattern?
[18:46:02] <andypugh> JT-Shop: That would seem like a good plan
[18:46:03] <Jymmm> JT-Shop: hot molten metal between your toes?
[18:46:06] <JT-Shop> just the one
[18:46:19] <JT-Shop> actually on the bottom of one toe
[18:47:07] <JT-Shop> just tacking some cannon parts on Georges cannon to help him out
[18:48:11] <JT-Shop> my garage used to be like that jdh
[18:48:30] <Tom_itx> teach the kids good habits
[18:48:47] <JT-Shop> no kids about, just me
[18:48:57] <Jymmm> JT-Shop IS the kid
[18:49:00] <JT-Shop> Thursday is a late day at the office for George
[18:49:16] <JT-Shop> no, I'm the yute
[18:49:27] <Tom_itx> probably just as well
[18:49:32] <Jymmm> JT-Shop: Ok Herman
[18:50:22] <Jymmm> JT-Shop: (You do realize who the judge was, right?)
[18:51:04] <JT-Shop> I have to make Ray wear my old blue jean shirt when he welds and he is an oncologist so you would think he knows better
[18:51:13] <JT-Shop> yea Jymmm it was his last movie
[18:51:35] <JT-Shop> and I think it was the best he ever did
[18:51:37] <Jymmm> JT-Shop: Was i? I didn't know. bummer, but a good movie
[18:52:28] <JT-Shop> The film was Fred Gwynnes final film appearance before his death on July 2, 1993, of pancreatic cancer.
[18:53:16] <Jymmm> I dont think I ever saw him in any other movies
[18:53:33] <JT-Shop> http://en.wikipedia.org/wiki/Fred_Gwynne
[18:54:29] <Jymmm> Fatal Attraction ?! musta been a cop
[18:55:07] <jdh> JT:and then you built an airconditioned shop?
[18:55:58] <JT-Shop> I insulated the garage then built a shop then found out how much good door seals mean for a garage
[18:56:04] <jdh> I might pick up a window unit this weekend. Not sure it will do much good
[18:56:19] <JT-Shop> do you have unsealed garage doors?
[18:56:37] <jdh> It has rubber flaps
[18:56:52] <JT-Shop> yea them things
[18:57:00] <jdh> not sure how sealed it is
[18:57:11] <JT-Shop> without them you loose so much it ain't funny
[18:57:32] <JT-Shop> I really like my LG window units, very quiet and cost effective
[18:58:15] <Jymmm> Yeah, my LG is pretty quiet compared to the other one I have.
[18:58:24] <JT-Shop> before good door seals my 15,000 btu window unit would only cool down within 15-20 of the unit
[18:58:39] <JT-Shop> feet of the unit
[18:59:16] <JT-Shop> after the garage stays 72-74 and the shop stays 70-72
[18:59:29] <JT-Shop> and nothing rusts anymore :-)
[18:59:34] <jdh> the garage is 16x25 I think. 10ft ceilings. Only insulates on rhe house side
[18:59:57] <Jymmm> jdh: own or rent?
[19:00:05] <JT-Shop> yea, that is only 400 sq ft
[19:00:07] <jdh> the windows are on the wrong side.
[19:00:23] <JT-Shop> you own?
[19:00:47] <jdh> own. a hole on the other side would be a problem though
[19:00:57] <JT-Shop> why is that?
[19:01:37] <jdh> the other sides have benches and shelves
[19:01:54] <Jymmm> blown in insulation
[19:01:56] <JT-Shop> my ac in the garage is over my shelvs
[19:02:00] <jdh> maybe over the back door
[19:02:42] <Jymmm> jdh: So, you want storage or coolage!
[19:02:46] <JT-Shop> yea, staple up some wall insulation in a couple of hours and pop in a window ac and you will be cool as a polar bear... well maybe not that cool
[19:02:54] <jdh> the walls are open studs for the most part
[19:03:12] <JT-Shop> cold air falls so it can be up high if needed
[19:03:36] <JT-Shop> yea you could slap up some bats of fiberlas in no time
[19:03:54] <Jymmm> I wouldn't put it near a door though
[19:04:22] <jdh> time to leave!
[19:17:59] <JT-Shop> Jymmm: you keeping your laser machine busy?
[19:18:21] <Jymmm> JT-Shop: not that the moment
[19:18:26] <Jymmm> s/that/at/
[19:19:07] <JT-Shop> I was just thinking about the dog tag thing and was wondering if that took off
[19:20:07] <Tom_itx> someone else is milling dog tags here i think
[19:20:14] <Jymmm> JT-Shop: People aren't buying trivial things right now, and petsmart/walmart with in-store engraving vending machines take a chunk.
[19:21:04] <Jymmm> JT-Shop: If I have a retail shop, might be different.
[19:21:20] <Tom_itx> sell bongs and dogtags?
[19:21:28] <JT-Shop> I know some big business guys who thought they would buy a factory and walse up to wal mart and have them as a customer... didn't work out that way
[19:21:44] <Jymmm> heh
[19:22:01] <Jymmm> Tom_itx: even that business is slow
[19:22:11] <Tom_itx> how fat can a LiIon battery get before you should show concern?
[19:22:22] <JT-Shop> people out there just roll their own
[19:22:23] <Jymmm> zero
[19:22:31] <Tom_itx> it's like 1.5x fatter now
[19:22:34] <Jymmm> JT-Shop: No, they'll use soda cans
[19:22:36] <Tom_itx> is it still good?
[19:22:41] <JT-Shop> lol
[19:22:53] <Jymmm> Tom_itx: Li-Ion or Ni-MH ?
[19:22:55] <Tom_itx> it broke the cover off the back
[19:23:15] <JT-Shop> crap Tom_itx run for you life!
[19:23:22] <Jymmm> Tom_itx: If it's Li-Ion, I'd toss it in a metal can NOW!
[19:23:32] <Tom_itx> Li Ion
[19:23:33] <Tom_itx> :)
[19:23:37] <Tom_itx> can i hit it with a hammer?
[19:23:46] <Valen> if its a foil pack some of them can get "puffy"
[19:24:03] <Tom_itx> it's more pregnant than puffy
[19:24:10] <JT-Shop> yea let me hold your beer Tom_itx
[19:24:28] <Valen> whats it in?
[19:24:34] <Jymmm> Let my hold your sherline Tom_itx
[19:24:41] <JT-Shop> lol
[19:25:04] <Tom_itx> ooo i could mill .035 off the top!
[19:25:06] <Jymmm> Tom_itx: here's a hammer, have at it! I'll be over here
[19:25:13] <JT-Shop> I had a rough day floating down the current river in a kayak today
[19:25:23] <Valen> Tom_itx: whats the battery in?
[19:25:28] <Tom_itx> nothing now
[19:25:32] <Tom_itx> was in my old ipaq
[19:25:37] <Valen> ahh
[19:25:38] <Jymmm> Valen: an explosive state
[19:25:45] <Tom_itx> still is apparently
[19:25:48] <Valen> just get another one if you want to keep using it
[19:25:50] <Tom_itx> can i toss it in the barbie?
[19:25:56] <Tom_itx> i did
[19:26:13] <Valen> they aren't *paticularly* explosive like that but capacity is greatly reduced
[19:26:23] <Jymmm> ipaq?! toss that inthe metal can too!
[19:26:28] <Valen> I'd get a turnigy one from http://www.hobbyking.com/hobbyking/store/index.rc
[19:26:35] <Tom_itx> no
[19:26:38] <Tom_itx> i need it
[19:26:46] <Jymmm> no you dont
[19:26:52] <Tom_itx> little you know
[19:27:13] <Jymmm> you THINK you need it
[19:27:17] * Valen had an ipaq somewhere around the place
[19:27:20] <Tom_itx> i use it 4hrs a day generally
[19:27:33] <Valen> my latest smartphone has caught up to it now lol
[19:27:33] <Jymmm> for what?
[19:27:39] <Tom_itx> stuff
[19:27:43] <Jymmm> lol
[19:27:46] <Tom_itx> i got 3
[19:27:52] <Tom_itx> 2 are identical
[19:27:52] <Valen> looking at porn whilst mobile
[19:28:16] <Tom_itx> i'd get an ipad for that
[19:28:27] <Valen> check out the samsung galaxy note Tom_itx, unless you have magical windows CE software they are pretty similar
[19:28:30] <Valen> no IRDA though
[19:29:42] * JT-Shop wanders inside for some chow
[19:29:47] <JT-Shop> see you guys later
[19:29:59] <Jymmm> Purina JT Chow
[19:33:56] <Tom_itx> i got magical CE software
[19:34:36] <Valen> some kind of parts managment thing innit?
[19:34:43] <Tom_itx> don't care to spend 1k to get it ported to a newer device
[19:40:51] <Valen> might need to do something like this
[19:40:52] <Valen> http://thereifixedit.failblog.org/2012/07/05/white-trash-repairs-playing-fifth-wheel/
[19:40:56] <Valen> lazy++
[20:11:47] <r00t4rd3d> anyone ever cut some 16mm supported rails?
[20:12:57] <r00t4rd3d> i dont think a sawzall and a metal blade is gonna do ti
[20:12:59] <r00t4rd3d> it
[20:13:10] <jdh> might, slowly.
[20:13:13] <jdh> could grind first
[20:13:16] <r00t4rd3d> the support, yeah the rail no.
[20:13:25] <jdh> grind the rail first
[20:13:38] <r00t4rd3d> with my skateboard?
[20:14:11] <jdh> with your $10 harborfreight 4" grinder
[20:14:16] <r00t4rd3d> lol
[20:14:31] <r00t4rd3d> i would chew it in half before i bought anything from hf
[20:14:45] <jdh> why?
[20:14:50] <r00t4rd3d> junk
[20:14:53] <jdh> what's wrong with a $10 disposable tool?
[20:15:08] <r00t4rd3d> waste of 10 bucks
[20:15:14] <r00t4rd3d> spend 50 and buy a real one
[20:19:10] <r00t4rd3d> i need a power bandsaw
[20:19:26] <r00t4rd3d> metal bandsaw
[20:19:28] * jdh doesn't mention his HF bandsaw
[20:19:31] <r00t4rd3d> power hacksaw
[20:19:52] <r00t4rd3d> i have a regular wood craftsman bandsaw
[20:20:30] <jdh> I have a regular HF 4x6 bandsaw
[20:20:34] <r00t4rd3d> ive read you should not put hacksaw bandsaw blades in them though
[20:20:54] <jdh> cuts great on aluminum, reasonably well on steel. Haven't tried stainless
[20:21:21] <r00t4rd3d> you have a metal blade in it?
[20:21:30] <r00t4rd3d> or upside down wood?
[20:21:37] <jdh> metal
[20:21:42] <jdh> it is a metal cutting bandsaw
[20:21:48] <r00t4rd3d> oh
[20:21:58] <r00t4rd3d> how much was that?
[20:22:08] <r00t4rd3d> 39.95?
[20:22:11] <r00t4rd3d> :)
[20:22:32] <jdh> http://www.harborfreight.com/horizontal-vertical-metal-cutting-bandsaw-93762.html
[20:22:35] <r00t4rd3d> its probably going to cost me 40 to have a machine shop cut them for me
[20:22:45] <r00t4rd3d> maybe 30
[20:22:49] <jdh> stand sucks. Good blade is $20
[20:23:06] <jdh> $179 coupon for the saw.
[20:23:17] <jdh> clamp the stock in the vise and walk away
[20:23:52] <r00t4rd3d> gimme a coupon
[20:25:17] <jdh> heh, this one expired 06/01/2012
[20:25:54] <jdh> home shop machinist, machinests workshop, maybe NRA mag has them

[20:38:59] <jdh> those both look identical to the HF ones, just a little more expensive

[20:42:19] <r00t4rd3d> its in their ad
[20:42:30] <jdh> heh, that's lame
[20:42:35] <jdh> perhaps he is just notching it
[20:42:49] <A2Sheds> heh, everyone knows it's best to use a chainsaw
[20:44:22] <jdh> I saw a mag article on making a table for one of those protable things. Looked like a lot of work for a $80 saw.
[20:44:40] <A2Sheds> seriously though, does Harbor Freight still have those 20-30% off any item coupons?
[20:45:04] <Jymmm> Just had 25% off on Kuly 4th only
[20:45:05] <jdh> 20% is normal
[20:45:36] <A2Sheds> wanted to get another sandblaster
[20:46:18] <A2Sheds> oh, it's already $90 off
[20:46:47] <Jymmm> A2Sheds: doens't matter
[20:47:07] <Jymmm> A2Sheds: 167.992
[20:48:11] <A2Sheds> Jymmm, whats the 167.992?
[20:48:31] <Jymmm> http://www.harborfreight.com/40-lb-capacity-floor-blast-cabinet-93608.html less 20%
[20:50:37] <jdh> I'd like to have one of thsoe for a few hours, but not bad enough to buy one, or buy a huge ass compressor for it.
[20:55:23] <A2Sheds> has anyone found a brand of Chinese machine tools that are made as well as say Fanuc?
[20:56:06] <Tom_itx> fanuc makes controls not machines
[20:56:11] <Tom_itx> but i doubt it
[20:56:14] <Tom_itx> jet is ok
[20:56:36] <Tom_itx> we had a manual jet (bridgeport) at the shop
[20:56:54] <A2Sheds> was thinking the old fanuc cnc
[20:58:08] <A2Sheds> heading there to do so shopping soon
[20:59:37] <A2Sheds> it should be interesting to see what they have in the showrooms
[21:01:25] <Valen> bandsaw wont go through hardened steel
[21:01:36] <Valen> not without a carbide blade
[21:01:40] <jdh> grind it
[21:01:47] <Tom_itx> yeah a good one will
[21:02:00] <Valen> its tool steel Vs hardened steel
[21:02:00] <Tom_itx> it may take a while
[21:02:15] <Valen> you might cut it, but you won't have any teeth left when its done
[21:02:36] <Valen> bah nvm r00t4rd3d left anyway
[21:02:47] * Valen was catching up
[21:02:49] <Tom_itx> heh
[21:03:07] <Valen> I want to get carbide or at least bimetal blades for our little bandsaw
[21:03:17] <Tom_itx> we ran Ti thru ours
[21:03:20] <Valen> too hard to find in our size
[21:03:23] <Valen> Ti isn't all that
[21:03:31] <Valen> its soft, though it can work harden
[21:03:33] <Tom_itx> tied a weight on the end of it and let it go
[21:03:36] <Tom_itx> yeah
[21:03:46] <Tom_itx> these were good size parts
[21:04:06] <Valen> I say Ti is like mixing Al and steel
[21:04:13] <Valen> its not some wonder material
[21:04:37] <Tom_itx> a bit tricky to cut
[21:04:56] <Valen> eh just don't be a pussy about it ;->
[21:04:57] <Tom_itx> once you figure it out it's easy
[21:05:25] <Valen> oh also be carefull of the swarf
[21:05:31] <Valen> it'll burn good if it gets going
[21:05:56] <Valen> firefighting procedure is to stop stuff around it from catching fire due to radiant heat and watch the sucker burn
[21:06:09] <Valen> (through a welding helmet)
[21:34:36] <A2Sheds> http://maxxtools.en.made-in-china.com/product/AqZxXtivLOVM/China-CNC-Milling-Machine-XK7132SD.html wow only $1K for a CNC MILLING MACHINE (must be a typo)
[21:36:23] <Thetawaves> is that door made out of rice paper?
[21:36:25] * Thetawaves lol
[22:26:40] <tjb1> Just adding once again that putting down hardibacker sucks
[22:26:45] <tjb1> Over 700 screws...
[22:27:19] <Valen> get a screwgun
[22:28:07] <tjb1> We have one but it uses special screws
[22:28:21] <Valen> :-<
[22:28:21] <Tom_itx> Valen, what was the material you used on your spindle head?
[22:28:25] <Tom_itx> for the casting
[22:28:29] <Valen> one we made up
[22:28:33] <Tom_itx> yeah
[22:28:40] <Valen> its a vynil ester resin and basalt
[22:28:56] <Tom_itx> work pretty good?
[22:28:59] <tjb1> Valen: http://cf.mp-cdn.net/ac/a9/38a6cafa6f3574a2638846b286cf.jpg
[22:29:11] <Valen> seems to
[22:29:25] <Valen> we are hoping to make a whole 5 axis mill out of the stuff lol
[22:29:49] <Valen> they look like bog standard wood screws to me tjb1
[22:30:07] <tjb1> They are coated so they dont rust and Lowes doesnt sell them for the Senco gun
[22:31:51] <tjb1> We stripped the head on about 70 of the cheap bastards
[22:32:37] <Valen> bah get stainless ones, pref posidrive
[22:32:39] <Valen> made of win
[22:34:19] <tjb1> Were done :)
[22:34:23] <tjb1> I never want to do that again
[22:35:00] <Valen> heh I am going to be putting a new roof on soon, so its on my mind too
[22:35:26] <Tom_itx> i used those on concrete backer board
[22:36:14] <tjb1> Cheap ass things were stripped before they hit the backerboard :P
[22:36:23] <tjb1> Went through about 4 batteries today too
[22:36:49] <tjb1> About burnt up a 1/2 dewalt corded drill mixing the thinset
[22:37:32] <tjb1> Im sure tiling is going to be just great.
[22:38:39] <tjb1> We also put on a metal roof and new septic tank this summer...

[22:39:57] <A2Sheds> Valen: how did the vinyl ester resin work out? what % of basalt did you use and what avg dia?
[22:40:27] <Valen> http://www.cnczone.com/forums/general_metal_working_machines/118358-phenolic_basalt_head_our_hm45.html
[22:41:35] <A2Sheds> ah ok, I remember that one
[22:44:27] <tjb1> Anyone know if you can tape the backerboard while tiling using the tile cement?
[22:46:20] <Tom_itx> if you're tiling over it why tape it?
[22:46:27] <tjb1> You have to tape the seams
[22:47:21] <tjb1> Probably the same reason you tape drywall seams
[23:03:46] <A2Sheds> it would be an interesting experiment to see what mixture holds up best, polyester, vinyl ester vs urethane's with various aggregates

[23:18:55] <nlkdavid> Is it ok to cut-n-paste an error log I'm getting when starting LinuxCNC?
[23:19:09] <A2Sheds> pastebin.ca
[23:19:20] <A2Sheds> then post the link
[23:22:52] <nlkdavid> http://pastebin.ca/2167522
[23:25:12] <toastydeath> actual machine tools from china aren't that bad
[23:25:41] <toastydeath> china has a lot of internal machine manufacturers that supply the export manufacturing base
[23:26:04] <A2Sheds> toastydeath, any particular brands you've tried besides Jet, Enco, Grissly etc
[23:27:12] <toastydeath> my old shop had several import lathes that were quite solidly built, but they were the price you'd expect for a turning center, not a 10x20 tabletop lathe

[23:35:02] <r00t4rd3d> grr
[23:35:10] <r00t4rd3d> how do i combine gcodes?
[23:37:30] <Valen> combine?
[23:40:03] <nlkdavid> I'm running the Vesa video drivers. Yesterday I tryed letting it install the Nvidia drivers labeled 'recommended', but then it wouldn't boot past the mouse pointer appearing, so I had to use safe graphics failsafe. This is my 1st attempt to start linuxcnc on this computer, I setup stepconf to my Fireball V90 & verified my parallel port address. When I run LinuCNC, after selecting a machine (whether my V90 or the samle ste
[23:41:16] <Valen> nlkdavid you got trimmed at "V90 or the samle ste"
[23:42:18] <r00t4rd3d> valen yeah, I have 3 different things i made and i want to combine them
[23:42:22] <r00t4rd3d> a pic and some text
[23:43:10] <Valen> you could just put them one after the other
[23:43:19] <r00t4rd3d> i have to do alot of them, 100
[23:43:19] <nlkdavid> or the samle stepper_inch) I get an error "LinuxCNC teminated with an error". the attached log is at http://pastebin.ca/2167522
[23:43:23] <Valen> perhaps with some offset settings
[23:43:51] <Valen> nlkdavid: your having issues with video card
[23:43:53] <r00t4rd3d> it would be 300 changes
[23:44:10] <Valen> i meant you can combine the gcode into one file
[23:44:18] <Valen> its just text
[23:44:19] <r00t4rd3d> oh
[23:44:32] <Valen> seriously learn the basics of gcode
[23:44:39] <Valen> you will understand whats going on then
[23:44:51] <r00t4rd3d> im sure i will over time
[23:44:51] <Valen> nlkdavid: what is the machine your running on?
[23:45:08] <Valen> its kinda like saying you will learn driving "over time"
[23:45:42] <nlkdavid> hang on, i'll get the specs
[23:45:55] <Valen> the computer right not the mill ;->
[23:45:59] <r00t4rd3d> no one jumps in a car and is an expert
[23:46:21] <Valen> yeah but its a good idea to read the road rules before you try driving
[23:47:01] <Valen> i'll take all of 20 minutes to know what the G1 G2 G0 and some of the initilisation stuff is
[23:47:16] <Valen> for what your doing you want to look at whatsitcalled cordinate spaces
[23:47:21] <Valen> offests or something
[23:47:42] <Valen> yeah G54 through G59 i think
[23:48:32] <Valen> that or a G92
[23:48:48] <Valen> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?CoordinateSystems
[23:49:15] <r00t4rd3d> ok ill check it out, thanks
[23:50:07] <Valen> that one is kinda confusing
[23:50:18] <r00t4rd3d> i think inkscape will do what i want
[23:50:36] <r00t4rd3d> if i save all my stuff to stl or whatever

[23:56:45] <Valen> have you run latency test on it nlkdavid?
[23:57:38] <nlkdavid> yes, stays under 10000ns of jitter
[23:57:57] <Valen> ok then
[23:58:58] <Valen> just need to work out what driver you want i think you probably need a legacy driver
