[13:16:38] <malcom2073> I want a trunion, with a rotary table in the bottom of it
[13:16:45] <malcom2073> trunnion
[13:17:44] <archivist> I want that plus a rotary sitting on it
[13:18:13] <archivist> then that bevel set up becomes easy
[13:21:02] -!- Dimroy has quit [Quit: Quitte]
[13:22:42] <MrFluffy> if you have a slotted trunnion, what you bolt to it doesnt matter provided it can take the weight and hold fast
[13:22:57] <MrFluffy> I used a machine table for the trunnion bed
[13:23:22] <MrFluffy> although it was smaller, so I have a trunnion shelf rather than a table in reality
[13:24:29] <MrFluffy> it was just right size for that rotary table to mount, except that idea wooden go well now (groan)

[14:27:09] <ssi> morn
[14:27:22] <skunkworks> acceleration anyone? https://www.youtube.com/watch?v=CeSselMw3Dk
[14:28:51] <cradek> heh that's not going to be a very good thread is it
[14:29:03] -!- patrickarlt has quit [Ping timeout: 255 seconds]
[14:29:06] <ssi> variable pitch thread :D
[14:29:11] <cradek> he doesn't even start off the end of it...
[14:29:19] -!- lerman has quit [Ping timeout: 265 seconds]
[14:29:45] <ssi> looks cool anyway hahah
[14:31:47] <malcom2073> Isn't it normally good practice to go in->out for threads?
[14:31:48] <malcom2073> rather than out->in?
[14:31:59] <ssi> not necessarily
[14:32:20] <ssi> you'd need a tool on the backside or upside down to do in->out, or else you end up with left threads :)
[14:32:29] <malcom2073> I guess with cnc it doesn't *really* matter
[14:32:31] <malcom2073> Heh
[14:32:57] <malcom2073> Or spin the spindle the other way
[14:32:57] <skunkworks> He make a comment at the end that he needs to start back
[14:33:15] <cradek> on a manual lathe there's some benefit for threading backwards because you start in the tight spot instead of trying to end there
[14:33:31] <ssi> you have to spin the spindle the other way to cut a right thread backwards
[14:33:32] <cradek> but in cnc going leftward is the clear win
[14:33:42] <ssi> but if you spin the spindle the other way you need the tool on the backside or upside down
[14:33:48] <cradek> yep
[14:34:06] <malcom2073> Gotcha
[14:34:15] <skunkworks> I bet he could increase the acceleration of the machine
[14:34:23] <cradek> yeah by 10x or more I bet
[14:34:33] <cradek> it's clearly misconfigured
[14:38:09] <archivist> the reverse pass sounds terrible too
[14:39:13] <ssi> yea I thought it was losing steps at first
[14:39:18] <ssi> sounds like resonance
[14:39:37] <cradek> he might have it turned way down because it's badly tuned
[14:40:17] <archivist> tuned? its a stepper :)
[14:40:18] <cradek> although ... it sounds like steppers, so maybe a terrible sequence of bad decisions has led him to an unfortunate situation
[14:41:23] <archivist> not seen a servo Denford yet

[14:42:07] <archivist> that model of his is a new one on me too
[14:46:20] <AGR> skunkworks: still getting the same error, Pin 'emcmot.01.enable' does not exit. In # Spindle Enable of hal file.
[14:46:23] <AGR> http://pastebin.com/d6Aj4eri
[14:46:45] <malcom2073> Ok I'm watching a 1940's video on threading haha
[14:47:04] -!- lerman has quit [Ping timeout: 246 seconds]
[14:51:03] <archivist> AGR, if you only loaded one then that wont exist , I see earlier there is an emcmot.00.enable
[14:51:59] <AGR> archivist: what should I change
[14:52:25] <ssi> there's only one emcmot component loaded, so they should all be emcmot.00
[14:52:31] <archivist> I dont know what emcmot does without reading docs
[14:52:46] <ssi> but I don't tihnk you can drive the same enable signal from three places
[14:52:51] <ssi> I'm not sure what you're trying to do exactly
[14:53:08] <archivist> I am thinking what ssi is too
[14:54:14] <AGR> tring to drive VFD with 0-10 volts out
[14:56:23] <AGR> I got the same error when using emcmot.00
[14:57:04] <archivist> get small chunks working
[14:57:18] <archivist> understand what the signals are
[15:03:58] <_methods> so for a 7i76E do you need a second ethernet card for control of the cnc?
[15:04:17] <_methods> or can you just plug that monkey into a switch and control it from anywhere on your network?
[15:04:34] <ssi> I think you want a dedicated link
[15:04:47] <_methods> i kinda figured that but wasn't sure
[15:05:09] <_methods> so just dedicate a 2nd nic to the control
[15:05:12] <ssi> yeah
[15:05:20] <furrywolf> _methods: you can plug it in through any sequence of switches, hubs, etc, but network collisions may harm realtimeness.
[15:05:45] <furrywolf> I once asked if you could plug it into a wireless bridge, mostly as a joke, and pcw said yes...
[15:06:00] <_methods> still interesting
[15:06:00] <ssi> yes, and more specifically, if you are trying to do control over the same nic that's handling your primary network traffic, you're likely to get unacceptable latency
[15:06:32] -!- KimK has quit [Ping timeout: 265 seconds]
[15:06:43] <furrywolf> that said, if you only use the machine for other network tasks while you're not machining, it's probably fine.
[15:06:49] <_methods> i'm going to order a 7i76e or the 5i25/7i76 combo today
[15:06:56] <_methods> just trying to make final decision
[15:07:08] <ssi> personally I'd probably stick with the 5i25
[15:07:12] <furrywolf> 7i76e was out of stock as of two weeks ago, but pcw probably has them done by now...
[15:07:20] <os1r1s> _methods: What machine are you controlling?
[15:07:25] <_methods> 5i25 is tried and true
[15:07:43] <_methods> an x2
[15:08:00] <os1r1s> servos or steppers?
[15:08:03] <_methods> steppers
[15:08:16] <os1r1s> Ahh, ok
[15:08:25] <furrywolf> I want a 7i76e so I can plug it into my laptop, but get more pins than my current parport setup.
[15:08:36] -!- KimK [KimK!~Kim__@ip68-102-188-176.ks.ok.cox.net] has joined #linuxcnc
[15:08:37] <os1r1s> I have a small mill I'm considering converting to servos.
[15:08:48] <_methods> yeah i can just buy a 7i77 later
[15:08:50] <_methods> to go servo
[15:09:00] <_methods> i plan on adding a servo 4th axis
[15:10:02] <_methods> but by then i may have a small horizontal to convert
[15:10:10] <_methods> probably put the servos on that
[15:10:31] <skunkworks_> get rid rid of net spindle-enable emcmot.01.enable
[15:11:22] <_methods> i picked up my bandsaw a couple weeks ago so now i gotta get a good air compressor and a tig rig
[15:11:22] -!- nofxx has quit [Ping timeout: 265 seconds]
[15:11:25] <AGR> shunkworks: thanks, will do
[15:11:32] <_methods> those 2 come before servo toys
[15:12:44] <os1r1s> Has anyone use an AMC 12A8 crushed servo amp?
[15:12:51] <furrywolf> looking at the variable-thread-pitch video, I thought linuxcnc was smart enough to use a trapezoidal cutting path such that the acceleration occoured while the tool wasn't cutting, and would give some kind of following error if it couldn't command the tool to keep up with the spindle?
[15:12:56] <ssi> I have used similar amps
[15:13:10] <ssi> I've used 30A8 and I've used a bunch of their brushless amps
[15:13:56] <cradek> furrywolf: the best you can do is start way right of the part and accelerate in air
[15:14:06] <cradek> I don't understand what you mean by trapezoidal
[15:14:08] <furrywolf> as in, from my understanding, you'd have to seriously work to make it suck that badly?
[15:14:16] -!- lerman_ has quit [Ping timeout: 265 seconds]
[15:14:47] <cradek> well, his machine is misconfigured and he's not starting in an appropriate place, making his results as bad as possible
[15:14:49] <furrywolf> rather than moving in and out of the cut straight, it'd move in at an angle... so your cutting path would be \___/ instead of |___|.
[15:15:16] <cradek> yes it can do that
[15:15:23] <furrywolf> shouldn't an excessive difference between where the cutter is and where the cutter should be to synchronize with the spindle give an error?
[15:15:27] <os1r1s> ssi: Would 3 of those + a 7i77 + 5i25 get me control over these motors? http://www.cadcamcadcam.com/motorservoglobepm-dc.aspx
[15:15:28] <ssi> yes there are lead in and lead out parameters
[15:15:51] <cradek> no, there's no error, because it's normal to have to accelerate
[15:16:04] <cradek> you just need to do it outside the part
[15:16:23] <furrywolf> ignoring acceleration, let's say your axis maximum velocity was less than needed to cut the thread at that spindle speed... that should definitely be an error.
[15:16:32] <ssi> os1r1s: I don't see why not
[15:16:56] <ssi> 12A8 is an up to 80V, 12A peak, 6A continuous brushed drive
[15:17:05] <ssi> the motors fit within those parameters
[15:17:06] <cradek> that is in theory detectable but isn't currently detected
[15:17:24] <furrywolf> in that case... feature request! :P
[15:17:35] <furrywolf> failure to properly synchronize with the spindle should be an error
[15:17:35] <ssi> furrywolf: spindle synchronized motion isn't subject to the following error rules
[15:17:36] <os1r1s> ssi: Think the HEDS encoders will work with linuxcnc too
[15:17:36] <cradek> patches thoughtfully considered
[15:17:58] <ssi> os1r1s: I don't know what a HEDS encoder is
[15:18:05] <cradek> there are soooo many ways to cut a bad thread on a lathe
[15:18:13] <furrywolf> heh. I don't even have a spindle encoder built yet. I bought the opto sensors, but I need the 7i76e to connect them...
[15:18:19] <ssi> some quick googling suggests it's a single ended TTL encoder
[15:18:26] <cradek> the one you want to detect is one of the few that's extremely obvious to the user
[15:18:39] <ssi> incremental
[15:18:47] <furrywolf> mill is on indefinite hold... until I can start working again, I'm worse than broke. :(
[15:18:48] <ssi> in which case, yes, 7i77 will count them just fine
[15:18:51] <os1r1s> ssi: These .. http://www.digikey.com/catalog/en/partgroup/hedm-55xx-and-heds-55xx-56xx-series/12510
[15:19:22] <ssi> yeah those should work fine
[15:19:36] <ssi> the 7i77 is configured for differential encoders by default, you'll have to jumper it for single ended encoders
[15:19:39] <os1r1s> ssi: And you would plug the encoders directly into the 7i77 and not 12a8s, right?
[15:19:46] <ssi> correct
[15:20:14] <ssi> now, in that arrangement you'll have no velocity feedback to the drive
[15:20:18] <ssi> so you'll need to run it in current mode
[15:20:20] <ssi> and tune accordingly
[15:20:32] <furrywolf> I seem to be slowly getting better... I have most of my feeling back in my left leg as long as I don't do anything involving moving. heh.
[15:20:41] <os1r1s> ssi: Would that be a big disadvantage?
[15:20:48] <ssi> no, it's just different
[15:21:10] <os1r1s> Which component is creating that limitation?
[15:21:39] <ssi> the drives require tachometer feedback for velocity mode, and you have no tachometers on your motors
[15:21:52] <os1r1s> Ahh, ok
[15:22:13] <os1r1s> ssi: I haven't bought those motors, they are just the ones I was considering. I need ones with a nema23 mount.
[15:22:32] <ssi> I'm not aware of any off the shelf servos for reasonable prices that have encoders and tachometers
[15:22:48] <ssi> some AMC drives can use the encoder for velocity feedback, but the 12A8 is not one of them
[15:22:53] -!- podarok has quit [Quit: Залишаю]
[15:23:03] * furrywolf isn't aware of any off-the-shelf servos for reasonable prices, period.
[15:23:51] <ssi> here you go
[15:23:51] <ssi> http://www.hobbyking.com/hobbyking/store/__662__HXT900_9g_1_6kg_12sec_Micro_Servo.html
[15:24:23] <ssi> buy three times as many as you think you need, cause they have a pretty high infant mortality rate
[15:24:31] -!- kawazaki22222222 has quit [Read error: Connection reset by peer]
[15:25:13] <os1r1s> Gotcha. Some of those amps have encoder inputs don't they? Can you normally bypass that and go straight to the mesa board?
[15:25:29] * furrywolf thinks ssi is fully aware that's not the right type of servo. :P
[15:25:38] <ssi> yes, in most cases the encoder input is just for velocity feedback
[15:25:53] <ssi> you can likely bring the encoder to both the mesa and the amp
[15:26:03] <furrywolf> anyway, those have encoders. :P
[15:26:05] <ssi> the mesa counts it for absolute position, and the amp uses it for velocity feedback
[15:26:21] <ssi> furrywolf: you can build a cnc machine with one, quitcherbitchen
[15:26:27] <ssi> s/one/several
[15:26:46] <ssi> https://hackadaycom.files.wordpress.com/2014/02/plotclock.jpg?w=765&h=573
[15:26:52] <os1r1s> ssi: So you can bypass the encoder on the 320x for example too?
[15:27:09] <ssi> no
[15:27:18] <ssi> the gecko servo drives are not what you want
[15:27:22] <ssi> they're position mode drives
[15:27:38] <ssi> they count the encoder, they close the position loop, and you interface with them via step/dir as if they were a stepper
[15:27:56] <skunkworks_> you want velocity or current/voltage mode drives...
[15:28:00] <ssi> those drives are for people who run inferior windows-based control software that doesn't know how to close the position loop
[15:30:22] <_methods> http://www.ebay.com/itm/SAMSUNG-200W-SERVO-PACK-DRIVER-MOTOR-3-AXIS-CNC-ROUTER/260742909935
[15:30:42] <os1r1s> ssi: Gotcha. Its intersting that the 7i77 doesn't have a 0-10v for spindle control. I'm guessing it can't use a spare servo output.
[15:30:50] <ssi> sure it can
[15:31:15] <ssi> the first five enables are ganged together, the sixth enable is separate
[15:31:28] <ssi> the reason for that is because typically you'll use the sixth channel for spindle, and you want to be able to enable it separately
[15:31:34] <ssi> whereas you normally enable all the axes together
[15:32:03] <ssi> that way you also get an encoder counter for your spindle
[15:32:44] <os1r1s> ssi: Oh, cool. That could work well then. It would go to a KBIC control. So hopefully that will link up.
[15:32:51] <os1r1s> I control it via a G540 today
[15:33:24] <ssi> any reason not to stick with the G540 and steppers?
[15:34:52] <os1r1s> ssi: Not particularly. I'm interested in learning how to make it work with servos. Beyond that and the standard touted benefits of servos, I don't have a need.
[15:35:02] -!- patrickarlt has quit [Remote host closed the connection]
[15:35:14] <os1r1s> Would you advise against it?
[15:35:39] <ssi> if you have a working machine with steppers and drives, I'm not sure I'd pull it apart and start over
[15:35:47] <ssi> converting to servos is going to be a fair amount of work
[15:35:58] <ssi> there's a pretty substantial learning curve
[15:36:10] <ssi> if it were me, I'd probably want to build a second machine and go servo on it
[15:36:18] <ssi> but I'm the nut with like six machines
[15:36:28] <_methods> n00b

[15:38:50] <ssi> cause I have the cnc plasma table which mostly works at the moment, the surface grinder, and the cnc punch press which doesn't work
[15:38:53] <ssi> so that's nine machines

[15:49:47] <cradek> the long-life burroughs nixies will last for decades *of active use*
[15:49:59] <cradek> the b5991 etc models
[15:50:22] <cradek> in my clock that's run for 14? years now I see no darkening yet
[15:50:25] <furrywolf> all my nixies are good except one has a short between one cathode and part of the frame, so it excessively glows.
[15:50:40] <cradek> the "long life" models have mercury in them and it works great
[15:51:12] <cradek> and ... somewhere I have a box of 100 or so of them
[15:51:21] <archivist> only decades, the ones used in late sixties early seventies HP counters are the ones I am moaning about, the drive is odd too
[15:51:21] <cradek> a many-lifetime supply
[15:51:53] <cradek> archivist: are they darkened so bad they're unreadable?
[15:52:04] <furrywolf> http://fw.bushytails.net/nixies/fluke10mv.jpg nixies. :)
[15:52:11] <archivist> HP used an opto coupling between the counter and nixie
[15:52:11] <cradek> archivist: the non-mercuried versions really darken fast - a few years
[15:52:33] <cradek> yeah the optical bcd-decoder thing was wild
[15:52:40] <cradek> terrible idea :-)
[15:52:43] <archivist> inter electrode problems usually
[15:52:52] <Connor> I had a nice volt meter that was Nixie based.. not sure what happened to it...
[15:53:12] <furrywolf> http://fw.bushytails.net/nixies/fluke10v.jpg there, you can see the bad tube in that image... the 0 cathode shorts to some of the frame. I've been ignoring it, as it's entirely functional.
[15:53:53] <archivist> cradek, re visit the counter, not even proper bcd iirc really odd decade counters
[15:54:06] <furrywolf> this multimeter has some funky designs... for example, the display is stored as analog voltages on a set of capacitors, one capacitor per digit.... 1V makes it display 1, etc.
[15:54:35] <cradek> some were biquinary (two anode cages in the tubes)
[15:55:06] <archivist> I wonder if a high voltage could burn off a short

[15:55:31] <cradek> I know too much current makes the neon quit working...
[15:55:38] <furrywolf> archivist: it works. it's a very minor issue having a bit of extra glowing under one tube only when zero is displayed. :)
[15:55:39] <cradek> "pop"
[15:56:12] <furrywolf> for how old that multimeter is, that's a remarkably minor failure. I'm always impressed it's still accurate to the microvolt. :P
[15:56:37] <cradek> that you have any two things that agree on microvolts is pretty incredible
[15:56:37] <furrywolf> http://fw.bushytails.net/nixies/fluke01.jpg I enter 12.345mv (millivolts, not volts!) on my dial-a-source, it displays 12.345mv... hard to beat that!
[15:57:01] <furrywolf> cradek: yep. hence why I'm impressed.
[15:57:16] <archivist> perhaps the error is the same as the source :)
[15:57:20] <furrywolf> the voltage source is... *thinks*... rated for .0015% or something like that.
[15:57:28] <furrywolf> archivist: entirely possible. :)
[15:57:34] <cncjerry> good morning, at what level of the code do I need to be to have the tolerance_Inch active? I am having trouble with arcs missing due to rounding. The errors are always like .0005526 for some reason unless I change my CNC machining and fixture accuracy to .000001 which means older code would have to be reformatted
[15:57:34] * archivist ducks and runs
[15:58:45] <cradek> cncjerry: can you transcribe an actual error please?
[15:59:08] <furrywolf> I was also impressed with Fluke's customer support... the sampling rate circuit stopped working. I asked fluke for a service manual, and got a response along the lines of "not only do we not have one, but no one who's ever seen one still works here. but we'll see what we can do..."
[15:59:20] <furrywolf> two weeks later I got an email "we bought one and scanned it. here's the pdf. enjoy!"
[16:00:03] <ssi> speaking of fluke
[16:00:17] <ssi> I wonder how much it would cost to have my 189 overhauled
[16:00:20] <cncjerry> I'll go down and load some code but basically, it is the arc to center error, absolute error is .00005526. The arcs vary. I can post the lines that don't run
[16:00:24] <archivist> furrywolf, whats the model number
[16:00:56] <furrywolf> archivist: don't remember. the PDF is on their website now. they've started a project to put all their service manuals, current and historical, online.

[16:01:34] <furrywolf> it was odd working on it... many things in it are not built like modern things.
[16:01:44] <furrywolf> the analog memory is just one example
[16:01:57] <furrywolf> it also uses unobtainium logic chips running at weird voltages...
[16:02:12] <furrywolf> I think it's an 8350A
[16:02:22] <_methods> cncjerry: a sample of your code that is making the error pastebin'd would be helpful also

[16:02:31] <archivist> I have a counter that uses analogue memory to work a meter movement that rotated a film and projects the numbers
[16:02:40] <furrywolf> hrmm, that's not right.

[16:10:25] <cradek> cncjerry: you should update to the latest 2.6. it has more sensible defaults and it's also a configurable tolerance
[16:10:42] <cncjerry> can I upgrade without wiping the system?
[16:10:46] <cradek> your only other remedy is add those missing numbers after the decimals in IJ words in your gcode
[16:10:54] <cradek> what OS is it?
[16:10:56] <furrywolf> actually, you should upgrade to the latest 2.7... complaints about 2.6.8's trajectory planner are too frequent. :)
[16:11:08] <archivist> furrywolf, I think this is the one I had then scrapped http://www.ebay.com/itm/Fluke-8375A-Digital-Multimeter-Nixie-Tubes-/281737842450
[16:11:10] <cradek> 2.7 is not released
[16:11:17] <cncjerry> I used the load and go cd to just put it down on the system
[16:11:47] <cradek> sure but which OS is it? we've made those for 10 years.
[16:12:21] <furrywolf> the thing I most regret scrapping is a tektronix scientist calculator. I kick myself pretty hard over that one.
[16:12:34] <cncjerry> let me go look
[16:12:45] <furrywolf> http://www.oldcalculatormuseum.com/tek909.html I had one of those.
[16:13:37] <cradek> cncjerry: if it's lucid, see updating instructions here: http://linuxcnc.org/docs/html/common/Updating_LinuxCNC.html#_updating_from_2_5_x_to_2_6_x
[16:15:10] -!- md-2 has quit [Quit: Leaving...]
[16:16:04] <furrywolf> cradek: there's been a number of complaints in the last month or two about stupid behavior from the trajectory planner... there's nothing in the 2.6.8 changelog about it, but some people complain it exact stops even with G64 Pwhatever, other people complain it rounds corners no matter what P is...
[16:16:07] <cncjerry> yes,. 10.04 LTS says Lucid under it. so 2.6 has that tolerance_inch param?
[16:16:55] <furrywolf> upgrading to 2.7 seems to make the complaints go away
[16:18:15] <furrywolf> archivist: not only did I have the calculator, I had the 2.5" thick service and programming manual... but back then it wasn't vintage, it was just an old piece of crap in the way...
[16:19:57] <archivist> furrywolf, I know the feeling...been there done that a few times, nothing can become r@re without some losses along the way
[16:20:39] <cradek> > interesting device called the "928 Instructor", that allows keypresses on the keyboard to be recorded in realtime on an audio cassette recorder, then played back (at the same speed) from the cassette.
[16:20:46] <cradek> wow

[16:25:28] <PCW> the TP with linuxcnc <2.7 works fine if you dont have lots of short segments
[16:25:30] <PCW> If you have exact stops and no blending its probably a gcode issue
[16:25:31] <PCW> 2.7 will run quite a bit faster on gcode with lots of segments because it has more lookahead

[17:29:23] <PetefromTn_> 48 quart coolers
[17:29:45] <ssi> have you verified material compatibility?
[17:29:54] <PetefromTn_> of?
[17:30:03] <ssi> I used rubbermaid tubs, cause they're polypropylene, which is compatible with both the strong caustic and strong acidic solutions
[17:30:18] <ssi> you have battery acid, what are you using for caustic?
[17:30:32] <PetefromTn_> the concensus here was that igloo coolers were made of the right stuff
[17:30:47] <ssi> Hard-side coolers: The exterior body of most Igloo hard-side coolers is made of high-density polyethylene, while the interior liner is made of FDA-grade polypropylene. The insulation is made of Ultratherm™ - a proprietary blend of polyurethane foam.
[17:30:52] <ssi> that ought to work
[17:30:53] <PetefromTn_> I have also seen quite a few youtube videos of nice setups using them

[17:32:15] <Connor> ah
[17:32:27] <PetefromTn_> usually they are like $30.00
[17:32:27] <Connor> Use the other 2 for different die colors
[17:32:39] <Jymmm> PetefromTn_: bastard! I just went yesterday and they didn't have shit in stock
[17:32:41] <PetefromTn_> I will not be using water based dyes
[17:32:55] <Connor> Oh? What are you using?
[17:33:05] <PetefromTn_> Jymmm I know I told them to get rid of them because you were coming
[17:33:21] <Tom_itx> i could go down to the local Coleman factory and pull some off the line...

[17:33:41] <Jymmm> PetefromTn_: I figurd something lie that
[17:34:47] <PetefromTn_> I got some nitrile gauntlets, a big nice full face mask, a small apron, two large containers of baking soda, and a bunch of other PPE related stuff.
[17:34:49] <Connor> PetefromTn_: but don't you need a tub for each of those ?
[17:34:51] <_methods> CaptHindsight: yeah we got it
[17:35:01] <PetefromTn_> each of what
[17:35:04] <_methods> i ended up having to go with sch10 5"
[17:35:13] <_methods> they didn't have any sch5
[17:35:18] <Connor> solvent based dyes.. for different colors...
[17:35:34] <PetefromTn_> well it depends on what you want to do.
[17:36:07] <PetefromTn_> apparently the nice thing about it is you can sponge it on, dip your parts in it, airbrush it on, and quite a few other methods of application.
[17:36:21] <Connor> Oh.
[17:36:31] <PetefromTn_> the only reason I will need any of the water based dyes is if I want to get fancy with splash anodizing.
[17:36:51] <furrywolf> have at least a gallon of pre-mixed baking soda+water. saturate the water with as much baking soda as you can. that way when you spill acid on yourself, you don't need to mix it...

[17:38:37] <PetefromTn_> TOTALLY
[17:38:40] <Tom_itx> heh
[17:39:01] <PetefromTn_> The biggest challenge I think will be just dealing with this large acid container.
[17:39:22] <ssi> PetefromTn_: are you not going to have a caustic bath?
[17:39:23] <PetefromTn_> it is a 5 gallon container and has a little orifice tube that you release the acid from
[17:39:30] <Tom_itx> i had ~5 gal of acid given to me when the local pcb fab shop closed
[17:39:34] <PetefromTn_> apparently I won't be needing one
[17:39:39] <Tom_itx> i didn't want to keep it so i gave it away
[17:39:42] <ssi> I'm pretty sure you do
[17:39:51] <ssi> it dissolves the existing oxide layer
[17:39:54] <PetefromTn_> not according to Captainhindsight
[17:40:17] <PetefromTn_> my parts are machined completely around their outside
[17:40:28] <ssi> doesn't matter... aluminum forms an oxide layer in seconds
[17:40:32] <PetefromTn_> besides if I need one I have enough containers here
[17:40:40] <ssi> you can't add your controlled oxide layer to existing oxide
[17:40:41] <PetefromTn_> and lye is locally available
[17:41:03] <PetefromTn_> you would have to ask Captainhindsight about that
[17:41:42] <PetefromTn_> he seems to think it is not necessary
[17:41:49] <ssi> eh I'm not that concerned about your success :D
[17:41:58] <PetefromTn_> Oh I am sure you are not
[17:42:32] <furrywolf> I need to get some battery alkaline one of these days.

[17:49:38] <furrywolf> <furrywolf> going to be fun.
[17:50:03] <_methods> the restaurant in beerfest was called shitz'n'gigglez
[17:50:03] <PetefromTn_> now it's time to put all this stuff to task and see what comes out the other end.
[17:50:23] <ssi> get it done
[17:50:27] <Tom_itx> PetefromTn_, take pics of your failed tests too so we can see the effects of contaminates etc
[17:50:32] <ssi> I expect to see splash anodized scope rails by six pm
[17:50:47] <PetefromTn_> I honestly wish I had more cash I want to build the kart I intend for the setup
[17:50:59] <ssi> shifter kart?!
[17:51:02] <ssi> high speed anodizing?!
[17:51:04] <PetefromTn_> that is gonna have to wait a bit so I will be crawling around on the floor here

[17:51:22] <PetefromTn_> no an anodization kart that I can roll in and out of the shop
[17:51:29] <_methods> schnitzengiggle
[17:51:30] <_methods> hahaha
[17:51:39] <Tom_itx> now you need a robotic arm to move the parts from tank to tank
[17:51:44] * PetefromTn_ thinks methods is high or something
[17:51:53] <PetefromTn_> thats not a bad idea
[17:52:11] * _methods loves beerfest
[17:52:19] <Tom_itx> hopefully my cards'll be here tomorrow so i can get my control back up and goin
[17:52:22] * PetefromTn_ loves Oktoberfest
[17:52:50] * ssi loves lamp
[17:52:52] <_methods> mmm pretzels
[17:52:55] <Tom_itx> i should end up with a spare set of cards
[17:53:02] <PetefromTn_> so I have this 48 quart cooler for the anodizing tank
[17:53:07] <Tom_itx> depending on my soldering skilz
[17:53:21] <ssi> Tom_itx: what kind of cards
[17:53:23] <Tom_itx> btw, how'd that USB plug come otu?
[17:53:24] <PetefromTn_> I was thinking I would put it a little above halfway full
[17:53:26] <Tom_itx> ssi, mesa
[17:53:30] <ssi> oic
[17:53:35] <Tom_itx> i had a mishap with a PSU
[17:53:43] <ssi> yea I've murdered a few mesa cards myself
[17:53:46] <Tom_itx> cheap chinese reg went bad
[17:53:49] <ssi> managed to fix them tho
[17:53:56] <ssi> peter's pretty generous with spares :D

[17:54:05] <Tom_itx> yes he is
[17:54:30] <Tom_itx> last one was 3 56pin tssops
[17:54:37] * furrywolf still needs a mesa setup
[17:54:43] <PetefromTn_> so I was thinking 4 gallons of acid to 4 gallons of water for the mixture
[17:54:55] <PetefromTn_> water first of course

[20:42:58] <cradek> are those inches?
[20:44:00] <cncjerry> yes, inches
[20:44:19] <cncjerry> do I have to reboot the system?
[20:44:25] <cradek> no, I agree it fails to load
[20:44:44] <cncjerry> what is the error you see?
[20:44:45] <cradek> can you re-post it with the missing decimal places added? having 5 in XY and only 3 in IJ is weird.
[20:44:59] <cncjerry> the rest are zeros
[20:45:08] <cradek> well obviously not
[20:45:37] <cncjerry> no kidding. but I thought 2.6.8 allowed errors up to .001"?
[20:45:40] <ssi> arcs make my head hurt :(
[20:45:57] <cradek> can you just re-post?

[20:46:33] <cradek> I bet the real problem isn't the .0005 inches, it's the .5% difference
[20:46:39] <cncjerry> yes, that is the same error I get.
[20:46:51] <cncjerry> can I post here somehow?

[20:51:42] <cradek> in 2.7 we attempted to make changes that allow truncating OR rounding to 3 decimals in inch, or 2 in mm
[20:52:19] <cncjerry> can I upgrade from 2.6.8 to 2.7?
[20:52:45] <cradek> if you have 5 decmials in XY on purpose, because you need that precision, be aware that your arcs really aren't going to be in the right place unless you fix the gcode

[20:53:30] <cncjerry> no, here
[20:53:59] <cradek> 2.7 is unreleased, but you can run a prerelease version
[20:55:54] <cncjerry> sorry, the problem is that for some reason, setting the fixture and machining accuracey to anything less than 1e-5 gives me the error. I think it is the crazy way catia generates code (obviously), but the killer is I never had this problem with the 2.3 release. I went to 2.5 a while back and if I am cutting something without doing linked arcs it runs fine.
[20:56:29] <cradek> huh, I would be very surprised to learn this code runs on 2.3 but not 2.5
[20:59:29] <cncjerry> don't know what to say, there is a bug in my IMS generated post processor clearly since the code is wrong. It is not off enough to dictate a 90.1 or 91.1 error. I tried setting everything to .0001 precision without luck thinking there was a conflict between dimensioned units and gcode, no luck. I've run thousands of programs thru 2.3
[20:59:47] <XXCoder> whoa. http://frankieflood.blogspot.ca/2015/05/laser-cured-powder-coat-on-acrylic.html
[21:00:24] <cradek> I can't even build 2.3 on debian to try it, yuck
[21:00:49] <cradek> yeah, it's not an incorrect center mode, it's just the rounding or truncating that's doing it
[21:00:56] <cncjerry> is there any way to bypass this error in 2.6.8? where can I get 2.7 and as before can I upgrade or do I need to wipe?

[21:18:05] <jdh> why do you have to modify axis?
[21:18:17] <andypugh> Well, the new Jetway motherboard was so much easier than the Gigabyte that it just isn’t funny. Not only was there no need to update the BIOS, I didn’t even need to install an OS, it booted straight from the old SSD from the previous MB.
[21:19:04] <andypugh> And, as a bonus, my Touchscreen is now 1280x1024 rather than 1024x768. Which is very odd because I was certain that 1024x768 was the native resolution.
[21:19:07] <_methods> yeah i've had decent luck with jetways myself
[21:19:08] <PetefromTn_> no such animal LOL
[21:21:31] <andypugh> It’s also a super-thin MB with an onboard PSU (takes 12V power). Which means I can use a short PCI riser and make more space in the box. All in all I am happy, though it was about twice the price of the Gigabyte one.
[21:21:52] <skunksleep> Yay!
[21:22:13] <_methods> jetway makes great sff stuff
[21:22:27] <os1r1s> andypugh: Not worried about the onboard graphics?
[21:22:32] <_methods> well so far in my experience with them
[21:22:50] <andypugh> GLXgears runs at 100 fps, so that part is good too.
[21:23:22] <skunksleep> What kind of latency?
[21:24:33] <andypugh> About 11k. It went up to 30k briefly doing “something” but this is a Mesa setup, so I am not too worried.
[21:25:03] <andypugh> Jetway JNF9C-2800 if anyone is interested.
[21:25:40] <skunksleep> Nice
[21:25:53] <cncjerry> I modify axis as I like certain control key combinations to do things. I think some of it was added in over the years like contr+arrows to do incremental jogs.

[22:19:58] <SWPLinux> the battery wasn't full, I had it shooting 1000 frames over 3 hours or so, and that didn't drain the battery
[22:20:09] <Jymmm> nice
[22:20:47] <SWPLinux> 36 for the ones in museums, usually 48 for award shows, and as little as 12 for things like the Color Run or other "activations"
[22:20:57] <Jymmm> ah
[22:21:17] <Jymmm> wait till you get to do 180 =)
[22:21:50] <SWPLinux> you can also shoot time lapse video, I did a 5-hour shoot of my back yard at 1 frame every 3 seconds. That did kill the battery, but I ended up with a 2-minute HD video instead of 1000 images ...

[23:28:03] <blockh34d> pretty sure its all through usb on rpi even the onboard ethernet is still weirdly through the usb? or same bus or something
[23:28:13] <blockh34d> there is a ethernet but i think it basically uses the usb

[23:32:40] <CaptHindsight> i though I had already warned everyone
[23:32:49] <blockh34d> ah well so i think machinekit plus bbb sounds solid
[23:33:04] <_methods> for a commercial product?
[23:33:12] <blockh34d> yah ultimately
[23:33:15] <CaptHindsight> if you don't need the GUI
[23:33:16] -!- patrickarlt has quit [Remote host closed the connection]
[23:33:39] <CaptHindsight> industrial commercial or consumer commercial?
[23:33:47] <blockh34d> _methods: you mentioned better sourced parts, do you have and recommendations?
[23:33:56] <blockh34d> its hard to say its kinda unique
[23:33:57] <CaptHindsight> the BBB is a toy
[23:33:59] <blockh34d> some sorta 3 carriage thing
[23:34:11] <malcom2073> The BBB works within its limitations

[23:34:15] <blockh34d> hmm so... odroid u3 maybe?
[23:34:24] <blockh34d> jetson tk-1?
[23:34:26] <CaptHindsight> the BBB is not an industrial board
[23:34:26] <blockh34d> whats it take
[23:34:31] <CaptHindsight> it's a dev board
[23:34:33] <malcom2073> I use it, but for a 3d printer, so my opinion is often considered invalid :-P
[23:34:46] <blockh34d> malcom2073: this is for a 3d printer though
[23:34:52] <malcom2073> Sshhhhhh
[23:34:53] <blockh34d> so maybe we're both invalid
[23:34:55] <malcom2073> don't mention that here ;)
[23:34:57] <blockh34d> haha
[23:35:00] <blockh34d> ok no its lasers
[23:35:03] <blockh34d> lots of lasers.
[23:35:06] <malcom2073> K lasers.
[23:35:25] <blockh34d> yah bbb does seem a bit toy like
[23:35:32] <malcom2073> Nah my main complaint with the BBB/machinekit is the fact that Axis tends to lock up, causing the machine to continue moving after you release a jog button on occasion.
[23:35:35] <CaptHindsight> 3d printers are fine, it's just glorified glue guns that people have issues with
[23:35:40] <malcom2073> Something about video taking over interrupts
[23:35:59] <blockh34d> malcom2073: that sounds pretty brutal
[23:36:05] <blockh34d> malcom2073: how often does that pop up?
[23:36:19] <CaptHindsight> blockh34d: why ARM?
[23:36:21] <malcom2073> blockh34d: For me, pretty often, but I've been told "That doesn't happen", so meh
[23:36:21] <malcom2073> :-P
[23:36:22] <blockh34d> especially during gcode prints

[23:36:28] <malcom2073> only during jogs
[23:36:37] <blockh34d> hmm well that might be mangable then
[23:36:54] <blockh34d> CaptHindsight: doesnt have to be i'm sure they're flexible i think they're more goal oriented
[23:37:08] <blockh34d> whats it going to take to make 5 axes + 3 extruders happen in an embedded way?
[23:37:11] <blockh34d> professionally
[23:37:15] <malcom2073> Tbh I'm going to be putting a mesaboard + small x86PC on it soon
[23:37:18] <CaptHindsight> why do large machine builders use PC's?
[23:37:20] <malcom2073> I'm tired of the video being crap/laggy.

[23:37:53] <zeeshan-laptop> @
[23:38:16] <malcom2073> Unknown, I don't have any way to measure FPS, but it's just bad. Throw machinekit on a BBB, start up axis, and play around, you'll see.
[23:38:17] <blockh34d> CaptHindsight: yeah i guess they're going more for consumer level? i'm not really sure
[23:38:22] -!- patrickarlt has quit [Ping timeout: 248 seconds]
[23:38:31] <blockh34d> CaptHindsight: just trying to work within the specs they've provided
[23:39:05] <blockh34d> yah it sounds like micro-atx style pc would be better
[23:39:14] <CaptHindsight> battery powered portable printer?
[23:39:20] <CaptHindsight> solar powered?
[23:39:23] <blockh34d> but why would it need 3 heads?
[23:39:40] <CaptHindsight> different materials
[23:39:53] <blockh34d> i feel like the 3 carriages thing is some weird substance / procedural thing like maybe they're printing diodes and each of those is a different type of doped filament? i dunno
[23:40:02] <blockh34d> still could just put multiple extruders on one carriage though
[23:40:15] <blockh34d> they put them on seperate ones so they could prime in between
[23:41:14] <blockh34d> its a bit mysterious to me obviously but i dont really need to know everything about it
[23:41:43] <CaptHindsight> maybe they don't know what they are doing
[23:41:50] <CaptHindsight> maybe they just have money
[23:41:58] <blockh34d> its actually already built and functional with basic ramps marlin/sprinter etc stuff and some relay based cheating to switch carriage motors
[23:41:59] <CaptHindsight> pretty common
[23:42:11] <blockh34d> i dunno i guess its possible but they make a really nice extruder
[23:42:25] <CaptHindsight> take about brute force vs elegance
[23:42:33] <blockh34d> and their hardware is always very legit
[23:43:02] <blockh34d> they made some crazy printer that prints solid glass
[23:43:15] <blockh34d> uses a rotary mounted torch to keep it in flames constantly
[23:43:24] <blockh34d> like a flame thrower almost its pretty intense
[23:43:33] <CaptHindsight> whats the budget for the BOM?
[23:43:45] <blockh34d> they've been pretty flexible about that
[23:43:48] <CaptHindsight> controller + drives + motors?
[23:43:53] <blockh34d> i feel like quality and size is more of a concern
[23:44:06] <blockh34d> i dont really understand the embedded thing
[23:44:12] <CaptHindsight> sounds like a hobby
[23:44:30] <blockh34d> maybe hobbiests are the target market?
[23:44:44] <blockh34d> hobbyist?
[23:44:46] <blockh34d> whatever
[23:44:51] <CaptHindsight> sounds like it
[23:45:06] <CaptHindsight> use the pooopieboard then
[23:45:13] <_methods> lol
[23:45:15] <blockh34d> yah cause they have the space and resources to not need the embedded thign so its some sort of aspect of this thing i guess
[23:45:29] <blockh34d> its kinda hacky to begin with though
[23:45:35] <blockh34d> and then my changes are not exactly elegant
[23:46:00] <_methods> have you tried #reprap
[23:46:01] <blockh34d> just makes me feel like the results are not going to be as good as if i used a more filled out and developed n-axis system like linuxcnc
[23:46:08] <blockh34d> oh yah i'm there now
[23:46:10] <_methods> that room is full of some real geniuses
[23:46:18] <blockh34d> thats true
[23:46:20] <_methods> they should be able to help you
[23:46:23] <blockh34d> not really
[23:46:26] <CaptHindsight> geeeneuses
[23:46:29] <blockh34d> they led me to poopieboard.
[23:47:16] <CaptHindsight> did his name begin with an A?
[23:47:31] <blockh34d> lol no actually they were talking to the client before me
[23:47:43] <blockh34d> client was all sold on smoothieboards and simplify3d for the whole thing
[23:48:01] <blockh34d> neither would have really been my first choice
[23:48:16] <malcom2073> s3d is fairly awesome though, albiet silly expensive
[23:48:24] <blockh34d> although smoothieboards have a little bit going for them
[23:48:32] <blockh34d> i havent really cared much for it yet
[23:48:41] <blockh34d> maybe i just need to try it more, i'm kinda picky
[23:48:45] <blockh34d> cura just did a whole thing
[23:48:47] <malcom2073> I tried smoothieboard,. I hear it works well for repraps, but can't run ballscrew printers
[23:48:50] <blockh34d> a very makerbot sort of thing
[23:49:08] <blockh34d> 15.06 is the version that jumped the shark
[23:49:44] <blockh34d> i hope daid brings back multiple extruder support and non-ultimaker printer support.
[23:50:17] <blockh34d> hey ok aside from all my other questions about weird 5axes 3dps... i want to make a cnc
[23:50:29] <blockh34d> just a basic, functional, entry level cnc and i'm totally fine with using a pc for it
[23:50:50] <blockh34d> i have a lot of nemas around already, aside from that what would i need, a mesaboard of some sort and linuxcnc?
[23:50:58] <malcom2073> You can get by without mesaboard
[23:50:59] <_methods> yeah
[23:51:11] <blockh34d> malcom2073: i like the sound of that, hows that work?
[23:51:11] <malcom2073> If your PC has a parallel port
[23:51:16] <_methods> i've got a couple mills using cheap ass chinese bobs
[23:51:17] <blockh34d> i'm sure i can find one that does
[23:51:30] <blockh34d> bobs?
[23:51:33] <blockh34d> i dont know that term
[23:51:37] <_methods> breakout board
[23:51:41] <blockh34d> oh i see
[23:51:46] <malcom2073> yeah parallel port -> breakout board -> stepper driver ->stepper
[23:52:08] <blockh34d> like a4798's or whatever the number is?
[23:52:20] <blockh34d> i already have a 3 channel board of that sort designed maybe i could just modify it
[23:52:32] <blockh34d> it was a daughterboard to smoothieboard to add more channels
[23:53:01] <blockh34d> so i would need a bob to plug into that, and the computer, which is running linuxcnc and i'm ready to rock eh
[23:53:05] <malcom2073> TB6600's are like $13 per axis

[23:53:10] <blockh34d> suggested build volumes for a first time?
[23:53:17] <malcom2073> Or yeah if you already have something
[23:53:20] <blockh34d> TB6600's, check gonna jot that down
[23:53:23] <malcom2073> What are you trying to do?

[23:53:31] <blockh34d> hmm i guess cut basic materials
[23:53:38] <blockh34d> wood acrylic maybe some alum
[23:53:40] <malcom2073> I have a couple of those, they're not bad. Unknown how long they last
[23:53:49] <malcom2073> If you stick with wood/acrylic, it makes the machine much easier to build
[23:54:00] <blockh34d> interesting
[23:54:09] <malcom2073> Are you looking to design your own?
[23:54:09] <blockh34d> some metal working would really be nice though
[23:54:24] <blockh34d> how much does it add to the process in terms of time/money expense, thoughts on that
[23:54:26] <malcom2073> Mill or router?
[23:54:38] <blockh34d> um
[23:54:38] <malcom2073> To design your own? It adds a lot, especially with trial/error :-P
[23:54:45] <blockh34d> i am really bad with terms can you maybe help me out here
[23:54:49] <blockh34d> whats the difference
[23:54:57] <malcom2073> routers typically cut things out of sheets of material
[23:55:04] <blockh34d> malcom2073: no, price difference of working with metals vs non metals
[23:55:06] <malcom2073> larger horizontal envelope in relation to vertical
[23:55:10] <blockh34d> soft metals anyways
[23:55:11] <blockh34d> alum
[23:55:16] <blockh34d> maybe brass
[23:55:27] <malcom2073> Eh... it means you have to make it a lot more sturdy
[23:55:38] <blockh34d> ok thats what i'm trying to do
[23:55:43] <blockh34d> intricate cut outlines from sheet material
[23:55:48] <blockh34d> and it doesnt have to be metal
[23:55:52] <blockh34d> screw metal then
[23:55:54] <blockh34d> for first time
[23:55:57] <blockh34d> f-it, whatever
[23:56:00] <malcom2073> Actually... hvave you seen the 6040's?
[23:56:03] <blockh34d> i think i'll be doing more HDPE anyways
[23:56:05] <blockh34d> no
[23:56:30] <malcom2073> http://www.ebay.com/itm/6040-CNC-ROUTER-ENGRAVER-DRILLING-ENGRAVING-MACHINE-CUTTER-1605-BALLSCREW-4-AXIS-/291054639648?pt=LH_DefaultDomain_0&hash=item43c4355a20
[23:56:46] <malcom2073> Take that, replace stepper drivers/control system with PC/linuxcnc/new drivers
[23:56:57] <malcom2073> It can cut sheet aluminum slowly
[23:57:34] -!- lerman has quit [Ping timeout: 256 seconds]
[23:57:38] <blockh34d> interesting
[23:57:45] <blockh34d> little more than i was trying to spend
[23:57:53] <CaptHindsight> has anyone found a small ballscrew router like the 6040's that don't need rebuilding and dialing in right out of the box?
[23:57:54] <blockh34d> i guess metal working doesnt come cheap
[23:58:42] <_methods> CaptHindsight: i've not found one
[23:58:43] <malcom2073> blockh34d: You could do one of these: http://www.shapeoko.com/
[23:58:50] <_methods> maybe cncrouter parts machines
[23:58:52] <malcom2073> I hear they can do sheet metal, but I don't believe it
[23:59:05] <_methods> they can't
[23:59:18] <_methods> unless you replace everything
[23:59:30] <blockh34d> what about water jets
[23:59:35] <_methods> lol
[23:59:37] <malcom2073> ugh their website sucks haha
[23:59:44] <CaptHindsight> http://www.shapeoko.com/frimg/iso.jpg pretty flimsy
[23:59:45] <blockh34d> insanely expensive?
[23:59:48] <blockh34d> sounds like it would be
[23:59:59] <_methods> water jets are very dangerous
