[03:28:33] <WiillenCMdesign> can anyone explain why the timing is off on the simulation version of linuxcnc
[03:28:53] <Valen> the time reported is only an estimate
[03:29:15] -!- i_tarzan [i_tarzan!~i_tarzan@] has joined #linuxcnc
[03:29:19] <WiillenCMdesign> okay because the feedrate looks way to fast to be right
[03:29:38] <WiillenCMdesign> plus i have a cycle time calculator on the gui im working on and it's not adding up, and i know its right
[03:29:56] <Valen> sure your not mixing imperial and metric?
[03:30:20] <WiillenCMdesign> hmmm im only using hal via hal components is there a setting for that in stepgen
[03:30:30] <Valen> nfi never used it
[03:30:58] <WiillenCMdesign> i wonder if limit3 velocity is in in/s or in/m
[03:31:50] <WiillenCMdesign> that would make sense about the units
[03:36:46] <Valen> is it off by a factor of 25?

[11:57:22] <Valen> well its obviously just using the open source support system right
[11:57:28] <Loetmichel> <- "what work? get orders, so i can do something!"
[11:57:34] <Valen> lol

[15:39:50] <tjb1> Good news, T-Slots is sending out replacement extrusions
[15:40:56] <jdh> why?
[15:45:14] <tjb1> That one is bent, the other is gashed all over the place
[15:45:34] <tjb1> http://sphotos.xx.fbcdn.net/hphotos-ash3/557213_4007142532937_1214748650_n.jpg
[15:47:04] <jdh> bummer. Damaged in shipping?
[15:48:26] <tjb1> Not sure, the other 10ft(gashed) isnt bent
[15:48:37] <tjb1> It was shrink wrapped right to this one
[15:49:02] <tjb1> But all the gashes are anodized so it was bad right after they extruded it...
[15:54:17] <FinboySlick> tjb1: Still a bummer that you have to wait for new extrusions.
[15:54:27] <tjb1> Im in no hurry at the moment :)
[15:54:44] <tjb1> I havent worked in over a week so it looks like the leftover of my student loan is gonna finish this
[15:54:46] <FinboySlick> tjb1: Still have to make room for it? ;)
[15:55:08] <tjb1> I guess I can build one badass 3D printer :D
[15:55:56] <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.
[15:56:25] <tjb1> I dont know what to do with those extrusions
[15:56:47] <tjb1> That bend starts at 26.5" from the end
[15:56:52] <tjb1> So I have nearly 8ft of a good piece
[15:57:13] <FinboySlick> tjb1: You could try to straighten it I guess.
[15:57:29] <FinboySlick> Worse that'll happen is that it'll still be bent.
[15:57:33] <tjb1> I thought about that…my luck is that the t slots would collaspe or something
[15:57:50] <tjb1> I could make a small router :D
[15:58:08] <Loetmichel> re @ home
[16:00:45] <FinboySlick> tjb1: Hmmm, how about some other kind of tool? Bandsaw, things like that you might need.
[16:01:13] <tjb1> Im not sure about making a bandsaw
[16:01:27] <FinboySlick> Or one of those motorized hacksaws.
[16:04:05] <jdh> used 26's for $2k
[16:04:11] <jdh> <urk>
[16:07:27] <tjb1> And…big surprise, makerslide is out of stock
[16:11:37] <Jymmm> Based on this illustration, I wouldn't buy/use it. http://makerslide.com/images/ms_long.jpg
[16:13:29] <tjb1> Wow now....
[16:13:51] <tjb1> I was gonna use it for a 3D printer Jymmm
[16:14:09] <tjb1> Boston Gear charges $109.54 for a 6ft piece of 20 PA, 20 Pitch rack...
[16:14:33] <tjb1> I can get 5 piece of that shipped for $254 from Moore Gear
[16:15:02] <tjb1> Jymmm: http://www.buildlog.net/blog/wp-content/uploads/2012/02/quantum_render_01.jpg
[16:15:07] <Jymmm> a 3d printer has no side force, you dont need anything that fancy
[16:15:48] <tjb1> Its only $0.011 an inch
[16:16:55] <tjb1> Sorry $0.011 a MM
[16:17:35] <tjb1> $6.69 for a 2ft piece

[16:59:37] <peeps> anyone here dealt with 3d scanning? what do you recommend?
[16:59:54] <IchGuckLive> 10Mw Read
[17:00:01] <IchGuckLive> Miliwatt
[17:00:25] <IchGuckLive> peeps: object size
[17:01:06] <IchGuckLive> Art or construction part peeps
[17:01:15] <peeps> construction part i suppose
[17:01:48] <IchGuckLive> for construction part i adwise probing
[17:02:12] <IchGuckLive> or simple gimp to incjet to pycam
[17:03:07] <IchGuckLive> homeuse -> http://www.david-laserscanner.com/
[17:03:19] <frallzor> tried that, not impressed
[17:03:43] <peeps> frallzor, what didn't you like?
[17:03:50] <frallzor> the results
[17:03:51] <IchGuckLive> it is as it is free
[17:05:00] <frallzor> pretty much used the starter kit
[17:05:03] <IchGuckLive> peeps: do you got a part eyample
[17:05:56] <IchGuckLive> example
[17:09:23] <peeps> someone else was asking me about it, i'm not sure what objects exactly, but they work with automotive suspension parts mostly
[17:10:05] <IchGuckLive> then its worth to get a profasional involved
[17:10:15] <IchGuckLive> or even reconstruct
[17:11:17] <FinboySlick> if you're decent enough with CAD, it's often faster to just re-model the part than to scan it.
[17:11:35] <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?
[17:12:08] <FinboySlick> peeps: This is not an area where low cost is very frequent.
[17:13:00] <FinboySlick> peeps: Another thing is that if you need to modify a scanned model, you're SOL beyond just scaling it up or down.
[17:15:02] <Loetmichel> hmmm
[17:15:10] <Loetmichel> i want to have a 3d measuring arm
[17:15:31] <FinboySlick> For measuring I can definitely see usefulness.
[17:15:42] <Loetmichel> the problem with remodeling is the lack of measurements possible on the "original" part
[17:16:12] <Loetmichel> how do you measure threads drilled into a freeform surface for example?
[17:16:22] <FinboySlick> Loetmichel: Yeah, but it's easy to tweak to size in CAD.
[17:16:42] <FinboySlick> If your scan isn't accurate, forget tweaking, you have to re-scan.
[17:16:54] <Loetmichel> right
[17:17:26] <Loetmichel> or convert the point cloud to beziers and hope for a cad which can simplify the .stl
[17:17:39] <FinboySlick> For very curvy things I can definitely see a point.
[17:18:14] <FinboySlick> But most of the mechanical bits don't typically have a lot of complicated curved surfaces.
[17:20:56] <Loetmichel> FinboySlick: i actually had to design and build a frame for holding an air filter into the front of a dell server

[17:21:46] <Loetmichel> finally made a cardboard template and cut it 'til it fits, then get the steel "mesh" and cut it after the flatened cardboard
[17:22:13] <Loetmichel> would be SO much simpler if i had a measuring machine to get the awkward corners of the front frame

[17:37:09] <FinboySlick> evil666: Only thing that comes to mind is that it might not like your version of mesa.
[17:37:23] <FinboySlick> evil666: But that's hardly helpful.
[17:37:47] <evil666> what should i do?
[17:37:54] <Loetmichel> syyl: the problem: i had needed the INNER form for the steel mesh, obviously
[17:38:47] <FinboySlick> Loetmichel: But they all looked like straight edges and arcs.
[17:39:04] <syyl> put a dial indicator with a long stylus on front of the height gauge and you are in buisness...
[17:39:14] <syyl> cant shock me with that :P
[17:40:02] <FinboySlick> It's also a pretty good use case for a touch probe.
[17:40:19] <Loetmichel> right, but i have none of this in the company
[17:40:26] <syyl> that converts your milling machine in a lowcost measuring machine ;)
[17:40:30] <FinboySlick> Loetmichel: Demand more tools.
[17:40:33] <Loetmichel> the only CNC mill i use in the company is my private one
[17:40:55] <Loetmichel> FinboySlick: i chan demand all that i want, dont mean i get any
[17:41:09] <Loetmichel> i am peading since 3 years to buy a cheap cnc mill

[17:42:18] <Loetmichel> and using it for the company... and want that to stop
[17:42:21] <FinboySlick> Yeah, but unless it has a pretty good work area, nobody will notice the sign.

[20:33:42] <andypugh> I see one for $200
[20:33:50] <Connor> This was for 107.00
[20:35:21] <Connor> Should have got it then.. 2.5" Might work...
[20:35:29] <andypugh> 1/5" for $89, but that is likely to be too small
[20:36:00] <andypugh> I still say make your own. You can then use a "pinch" design to give your spindle bearings an easier life.
[20:36:01] <Connor> 1 5/8" Yea. too small.. the 2 1/2" would be good.

[20:41:11] <Connor> I have a OLD regulator that probably could be used.. I think it's too old to use for Scuba now...
[20:41:19] <jdh> craiglist a cheap reg, put an OPV on it, cut off a LP hose and put a barb/NPT on it
[20:41:25] <Connor> not to mention, I've not been diving in over 15 years.
[20:41:35] <jdh> bummer
[20:41:58] <jdh> stop by rheas diving in maryville

[20:42:24] <Connor> this thing was like 15 years old when I got it used.
[20:42:44] <Connor> easy. I've never had it serviced.
[20:43:39] <Connor> How much pressure does the LP hose have ?
[20:44:09] <jdh> 145ish
[20:44:14] <Connor> The only HP hose is the one with the Gauge right ?
[20:44:34] <Connor> The main line, the Backup and the BC are all LP
[20:44:38] <jdh> you can adjust the LP (MP really) down to 100 or so
[20:45:27] <Connor> 140PSi with the 2.5" would get me around 2033Lbs. :)
[20:45:41] <Tom_itx> how much do you need?
[20:46:01] <jdh> most non-ancient regs can be run up to 165 or so before they run out of spring
[20:46:17] <Connor> Depends on how tight you tighten up the belleville washers.
[20:46:36] <Tom_itx> you get that much force on a retention knob it may well pop off
[20:46:55] <Jymmm> That can't be right.... 1.3mm thick http://www.harborfreight.com/pack-of-50-trash-bags-55-gallon-90519.html
[20:47:12] <Tom_itx> probably mil not mm
[20:47:14] <jdh> probably 1.3 mil
[20:47:33] <Jymmm> jdh: they say "extra thick"
[20:47:36] <Connor> Tom_itx: Retention knob? I.E. top hat?
[20:47:47] <Connor> It'll be a pinch type.
[20:47:48] <Jymmm> 1.3mil would be extra thin
[20:48:15] <Tom_itx> Connor, i dunno how you are designing it but our holders had retention knobs
[20:48:33] <Jymmm> 1.3 mil would be like produce bags, wouldn't it?
[20:48:43] <Connor> Tormach TTS.
[20:48:56] <Connor> Has a modified 3/4 R8 Collet.
[20:49:19] <jdh> what do you pinch?
[20:49:42] <Connor> top of the draw bar.. and a "top hat" that's threaded onto the spindle.
[20:50:03] <Connor> so, it doesn't put pressure on the spindle itself.
[20:50:11] <Connor> the washers are between.
[20:50:24] <jdh> you just push down on the drawbar, opposing the washers?
[20:51:07] <Connor> You push down onto of drawbar.. hole mount assembly raises. I plate UNDER the washers makes contact with a tophat..
[20:51:18] <Connor> and it squeezes the washers together.

[21:19:54] <mcenter> What is a good way to use linuxcnc with only two axis?
[21:21:08] <mcenter> I have two servos, mesa 5i25 + 7i77
[21:21:33] <mcenter> Baldor 26M +-10V drives
[21:22:39] <mcenter> I edited a HAL for two servos, but AXIS doesn't seem to like it.
[21:22:53] <Jymmm> cnc chop saw
[21:24:16] <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.
[21:26:22] <JT-Shop-> mcenter: can you describe "Axis doesn't seem to like it" a bit more specific?

[21:27:49] <mcenter> When I start linuxcnc, the AXIS display complains there is no Z axis, and my system locks up.
[21:30:20] <JT-Shop-> do you know where your ini file is?
[21:30:41] <Nick001-Shop> In the ini file axis= 1 more than what you have ---2axis is 3 axis in ini
[21:30:58] <JT-Shop-> I suspect that is not the problem
[21:31:51] <mcenter> @JT - I have it in ~/linuxcnc/config.
[21:32:05] <Nick001-Shop> Coordinates = x z or xy
[21:32:46] <JT-Shop-> open it up and in the [DISPLAY] section put OPEN_FILE = ""
[21:32:52] <mcenter> @Nick - xy
[21:33:25] <JT-Shop-> mcenter: the splash screen is 3 axis so do the above and it won't load it

[22:01:25] <JT-Shop-> you don't make something like that with skate wheel bearings and plain bearings
[22:01:49] <andypugh> You are going to be charging 20k at least, too.
[22:02:18] <andypugh> So, what's the payback volume on $20k worth of sample cards?
[22:03:03] <Jymmm> andypugh: IT's for the textile industries, so seeing "fashion" changes each season, myabe a lot
[22:04:27] <andypugh> My point is that to pay for itself the machine has to make many tens of thousands of items without breaking down.
[22:04:36] <JT-Shop-> seems they had a bit of configuration problems that was fixed with some tape on the plexiglas

[22:37:20] -!- mhaberler has quit [Quit: mhaberler]
[22:37:48] <alex4nder> r00t4rd3d: the easiest way to make this work is to have your joystick send keyboard events inside X
[22:38:13] <r00t4rd3d> I know, but how are you doing it without joy2key or some other app?
[22:39:04] <andypugh> It's _much_ better to use hal_input and connect the controller into the HAL layer
[22:39:08] <alex4nder> X has a joystick driver; just configure it to do the right thing
[22:39:14] <alex4nder> andypugh: much?
[22:39:18] <andypugh> Yes
[22:39:28] <r00t4rd3d> how do i do that?
[22:39:36] <andypugh> For example, you get analog jogging.
[22:39:42] <r00t4rd3d> i know nothing of hal
[22:39:42] <alex4nder> andypugh: why is a button press from the keyboard much worse than one from the joystick?
[22:39:55] <alex4nder> oh, I have that with hal, I almost never use it.
[22:40:03] <andypugh> PS3 controllers have analog joysticks
[22:40:08] <alex4nder> no shit?
[22:40:16] <alex4nder> they also have analog buttons. ;)
[22:40:40] <andypugh> You lose the analogue part with keyboard emulation.
[22:40:47] <r00t4rd3d> analog buttons
[22:40:48] <andypugh> Instructions here: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Simple_Remote_Pendant
[22:40:58] <r00t4rd3d> anal og butt ons
[22:41:07] <alex4nder> yes, PS3 buttons have pressure sensing
[22:41:09] <alex4nder> it works in linux
[22:41:33] <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.
[22:41:51] * alex4nder shrugs.
[22:43:16] <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.

[22:52:24] <WillenCMD> i used threading timeout's to a function ever millisecond
[22:52:48] <WillenCMD> it advances a hal pin by the feed rate converted to milliseconds
[22:53:13] <WillenCMD> if it gets ahaed of the position its not a problem
[22:53:42] <WillenCMD> on button release it reads the position-fb and re-sets the position command to the current position
[22:54:45] <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
[22:56:57] <WillenCMD> i also have a really nice num_pad module for gladevcp will be adding, its a touchscreen keyboard
[22:59:35] <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.
[23:00:53] <WillenCMD> i will definetly be adding it, as i look for feedback and code tweaks
[23:01:44] <WillenCMD> as of right now its 4000 lines of code
[23:02:14] <WillenCMD> not all in one module though, i have made seperate modules in case people would like to use them in a gui
[23:02:20] <WillenCMD> such as the num_pad
[23:02:38] <WillenCMD> the motion_controller is its own module
