[00:23:00] <r00t4rd3d> more infos
[00:23:06] <r00t4rd3d> what controller?
[00:23:08] -!- MattyMatt [[email protected]] has joined #linuxcnc
[00:24:24] <r00t4rd3d> what kinda computer are you trying to use and how are you connecting the controller to the pc ?
[00:25:39] <mrpostman> I am useing a dell computer coneccted via parallel cable
[00:26:08] <mrpostman> i am not sure of what controller it is
[00:30:37] <andypugh> You bought the router fully assembled?
[00:30:49] <mrpostman> yes
[00:31:03] <andypugh> Did it come with any documentation?
[00:31:18] -!- munktell has quit [Remote host closed the connection]
[00:31:32] -!- munktell [[email protected]] has joined #linuxcnc
[00:31:50] <mrpostman> yes and no has all the info to get it running in mach3 but that about it
[00:32:25] <andypugh> OK, that should be enough.
[00:32:54] <mrpostman> i thought so too
[00:32:54] <andypugh> That tells you which p-port pin each signal is on.
[00:33:19] <andypugh> So, how is it manifesting non-working-ness?
[00:33:39] <andypugh> (There are so many ways to not work, after all)
[00:33:40] <mrpostman> yes. I have done all that in linuxCNC but they dont move
[00:34:20] <andypugh> Do the DRO numbers on the screen move?
[00:34:27] <mrpostman> I am thinking that my parallel port is not active but dont know enough about linux to make it work
[00:34:31] <mrpostman> yes
[00:34:46] <andypugh> Has the router ever worked?
[00:35:06] <mrpostman> yes it works just fine in mach3
[00:35:21] <andypugh> On the same computer?
[00:35:25] <mrpostman> yes
[00:35:49] <andypugh> You used the same parport base-address for both?
[00:36:16] <mrpostman> i dont know?
[00:36:51] <andypugh> I don't even know if Mach needs to be told the parallel port address.
[00:37:19] <tjb1> Yes
[00:37:28] <andypugh> Are you familiar with command-line stuff?
[00:37:42] <mrpostman> some what
[00:37:56] <andypugh> cat /proc/ioports
[00:38:12] <andypugh> should list the parallel port and its address
[00:39:14] <mrpostman> ok i see it 0378-037a
[00:39:51] <andypugh> 0x378 is standard, so looks right. Is that what you used in stepconf?
[00:40:07] <mrpostman> i have 2 parports though both are parport0
[00:40:16] <mrpostman> yes
[00:40:39] <andypugh> They can't both be parport0.
[00:41:01] <tjb1> I think that is what its telling him with cat /proc/ioports
[00:41:05] <tjb1> Did it for me too
[00:41:34] <andypugh> 0x378 and 0x37a are (I think) different elements of the same port
[00:41:43] -!- sumpfralle1 [[email protected]] has joined #linuxcnc
[00:41:44] <mrpostman> one is 0378-037a and 0778-077a both say parport0

[00:46:22] <andypugh> Did you right the HAL bu hand, or using stepconf?
[00:47:26] <mrpostman> i got it i think steppers are responding now
[00:47:27] <andypugh> I mean to say, of course: Did you write the HAL by hand or by use of Stepconf.

[08:20:58] <toastydeath> ryans the number of steps per rotation is discrete
[08:21:15] <toastydeath> with some error, obviously
[08:21:31] <toastydeath> one of the big problem with gantry machines is the fact that you are never, no matter what you do, going to be off by a bit
[08:21:36] <toastydeath> on X1 and X2
[08:22:06] <toastydeath> but if it makes you feel better, your motors aren't going to be the major contributor in error
[08:22:33] <toastydeath> your actual distance standard will be (in most cases, a rack/pinion drive or a leadscrew)
[08:23:06] <toastydeath> if you use only one motor, you have to deal with the fact you've essentially got a big C frame machine with some added rigidity
[08:23:32] <toastydeath> but that you're still going to get progressively worse wag in the crossrail as the cutting head gets further from the driven rail
[08:25:39] -!- syyl [[email protected]] has joined #linuxcnc
[08:34:22] <RyanS> This actually seems like a pretty clever way of building
http://www.cooperman.talktalk.net/files/2.htm fixed gantry
[08:36:38] <toastydeath> the problem with cleverness is that you still have a problem
[08:36:43] <toastydeath> it just looks different
[08:36:49] <toastydeath> what you need to look at is the kinematic path
[08:37:02] <toastydeath> that is, the distance from the motor to the workpiece
[08:37:10] <toastydeath> drive system to workpiece, rather
[08:38:09] <RyanS> yeah but fixed gantry is more rigid?
[08:38:20] <toastydeath> oh, yeah
[08:38:20] <toastydeath> it is
[08:38:28] <toastydeath> i thought that was an undercarriage driven gantry
[08:38:30] <toastydeath> sorry about that
[08:38:45] <toastydeath> most big milling machines are fixed gantry mills
[08:38:57] <RyanS> but I wonder if this guy is a skilled welder
[08:39:20] <toastydeath> welding structural steel is easy
[08:39:59] <toastydeath> i like that design
[08:40:10] <toastydeath> the only downside is that your envelope is tiny
[08:40:15] <RyanS> cheap ass stick welder would do the trick?
[08:40:15] <toastydeath> which is why you rarely see it on routers
[08:40:21] <toastydeath> and pretty much only on milling machines
[08:40:33] <toastydeath> yep
[08:41:19] <RyanS> yeah I am sort of looking for hybrid mill/router
[08:41:40] <toastydeath> the issue is that commercial routers tend to move really fast
[08:41:47] <toastydeath> so they like to have the smallest mass moving
[08:41:55] <toastydeath> whereas a 20 hp mill doesn't care so much
[08:42:22] <toastydeath> emc isn't good at moving fast, so you're in the clear
[08:43:15] -!- emel has quit [Excess Flood]
[08:43:22] <Valen> EMC is fine at moving fast
[08:44:07] <RyanS> hmm.. That being said I think I'd rather a small desktop machine for little plastic & wood knick knacks
[08:44:13] <toastydeath> Valen, since when
[08:44:27] <Valen> why wouldnt it be?
[08:44:42] <toastydeath> lookahead
[08:44:47] <Valen> the only real issue people have is wanting to do raster scanning on lasers
[08:45:54] <toastydeath> maybe it's changed but i've seen several discussions where there's no solution for machining at 80+ inches a minute
[08:46:06] <toastydeath> because it hiccups if you have two or three corners in a short space
[08:46:24] <toastydeath> that could be resolved
[08:46:42] <toastydeath> lots of controls have that problem, including commercial ones
[08:46:49] <Valen> we have commanded it to run faster than that but i don't think our mill could keep up
[08:46:57] <Valen> acceleration wise
[08:47:31] <toastydeath> it usually pops up on retrofitted commerical routers
[08:47:43] <toastydeath> something that expects to be moving that fast
[08:48:37] <RyanS> you think $860 is a waste of money for this?
http://zentoolworks.com/index.php?cPath=44
[08:49:27] <toastydeath> no idea
[08:50:01] <RyanS> I've seen worse kits for more expensive. is what I mean..
[08:50:57] <RyanS> but 12x12" looks like it has too much Z travel for routing
[08:51:20] <toastydeath> don't dismiss z travel
[08:51:35] <toastydeath> endmills are fine and all but say you want to put a boring bar, longer drill, etc in there
[08:52:02] <toastydeath> you have to a) clear the part, and b) the tool has to be as long as the cut is deep
[08:52:21] <toastydeath> plus anything you're using to hold the part
[08:52:33] <RyanS> a boring bar in a plastic hobby router!?
[08:52:46] <toastydeath> sure
[08:52:53] <toastydeath> what's wrong with a boring bar in a plastic hobby router?
[08:53:33] <toastydeath> it's a more accurate hole than endmill interpolation, and you can just as easily control the cut depth
[08:53:50] <RyanS> too small to bore large holes on a machine like that?
[08:54:27] <Valen> pretty sure that one is made from MDF>
[08:54:28] <Valen> ?
[08:54:38] <RyanS> umm
[08:54:45] <RyanS> PVC
[08:54:47] <toastydeath> you can bore any size hole on nearly any machine
[08:54:57] <toastydeath> because the amount of cut you're taking is controlled by how you set the boring head
[08:55:05] <toastydeath> you can increase a bore by .001" per pass if you want
[08:55:11] <RyanS> "high density PVC"
[08:55:16] <Valen> just mill the holes out ;->
[08:55:25] <toastydeath> not an accurate hole
[08:55:32] <Valen> depends what you want it for
[08:55:46] <toastydeath> flame cut it
[08:56:21] <RyanS> hmm maybe it could cut acrylic or polycarbonate?
[08:57:04] <toastydeath> also i'd argue that the accuracy of a hole doesn't depend on what you want it for
[08:57:18] <toastydeath> the accuracy of a hole depends on how accurate the hole is, and whether or not that's overkill depends on what you want it for
[08:58:27] <Valen> you said its not an accurate hole, implying its going to be not good enough for something.
[08:58:41] <Valen> if he is making bearings sure
[08:58:49] <toastydeath> <toastydeath> it's a more accurate hole than endmill interpolation
[08:58:58] <toastydeath> i said A is more accurate than B
[08:59:04] <toastydeath> which is true.
[08:59:10] <toastydeath> zing!
[08:59:19] <Valen> but that machine would probably be good enough to sit a bearing in for most applications
[08:59:38] <Valen> IE good enough to put a pre packaged bearing into
[08:59:39] <toastydeath> relative accuracy is agnostic of purpose
[08:59:46] <Valen> (19:55:25) toastydeath: not an accurate hole
[09:00:17] <toastydeath> i don't see that anywhere
[09:00:30] <toastydeath> oh, now i do
[09:00:45] <toastydeath> either way, I stand by my assertion that interpolation isn't as accurate as boring regardless of what you want it for
[09:00:53] <toastydeath> whether or not you care about that extra accuracy is up to you
[09:00:57] <RyanS> You're having a holey war.... hawhawhaw
[09:01:13] <Valen> I'd say that it depends on the machine too
[09:01:17] <toastydeath> nope
[09:01:43] <Valen> a crappy boring bar setup could well produce a worse hole than a milled one
[09:01:49] <toastydeath> except it doesn't
[09:01:58] <RyanS> Or its holey irrelevant
[09:01:59] <toastydeath> because we understand the kinematics of spindles vs interpolation

[09:03:25] <Valen> i'd wager that those nice single point diamond cutter machines that mill out telescope mirrors better than 1/10th of a wavelength of light could cut a pretty decent hole
[09:04:00] <toastydeath> Jymmm, given a machine with a spindle holding a tool, the error in x-y from the bearing is added to the error from the two axes
[09:04:14] <toastydeath> whereas in boring, you only have the error from the bearing and no circular deformity from the axes
[09:05:23] <toastydeath> bearing error tends to be of two types, synchronous and asynchronous; asynchronous is mostly surface finish unless you're doing optics, then it counts
[09:05:54] <Jymmm> toastydeath: Now, recite Pi to a thousand digits from memory. You have 30s, ready.... GO!
[09:05:58] <toastydeath> synchronous error is a per-revolution constant displacement in the plane normal to rotation and results in a cutting error
[09:06:23] -!- archivist has quit [Ping timeout: 256 seconds]
[09:06:33] <RyanS> 3.91 something or rather?
[09:06:40] <Valen> if your machine has a proper measurement system that's independent of the actual cutting then bearing errors in a milling operation can be compensated for, which you cant do for a boring setup
[09:06:42] <toastydeath> i'm a math major, i'll allow it
[09:06:51] <toastydeath> Valen, actually, you can do it and it is done
[09:06:59] <toastydeath> so...
[09:07:07] <Valen> RyanS: american congress once defined it as 3 i believe

[09:09:44] <Jymmm> toastydeath: What is 'i' in math?
[09:09:59] <toastydeath> depends on the context, usually the imaginary unit
[09:10:11] <toastydeath> i^2 = -1
[09:10:21] <Jymmm> italic i
[09:10:29] <RyanS> current!
[09:10:35] <toastydeath> still depends on the context

[09:11:43] -!- mk0 [[email protected]] has joined #linuxcnc
[09:11:44] <toastydeath> commonly, i can be an indexing variable or an indexing set, it can be one of the orthonormal bases for R^3, it can be the imaginary unit

[09:12:45] <Jymmm> RyanS: No, that would be antenna theory.
[09:12:46] <toastydeath> RyanS, assume we have a spherical cow radiating milk uniformly in all directions
[09:12:47] <Valen> sure? that sounds like philosophy more
[09:13:26] <Valen> a school is under a budget crisis and has decided to axe either maths or philosophy
[09:13:32] <RyanS> We would have a big mess?
[09:13:35] <toastydeath> i'd axe math
[09:13:49] <Valen> so they get the heads of the 2 departments in and ask them to make a statement as to why they should be the one to stay
[09:13:54] <toastydeath> k-12 math education is a huge waste of time in its current incarnation
[09:14:06] <Valen> maths says "all we need is a blackboard, paper, pencils and a rubbish bin"
[09:14:14] <Valen> philosophy says "we don't need the bin"

[09:20:25] <Jymmm> RyanS: To the casual viewer, but it's pretty easy.
[09:21:37] <RyanS> They still use Turbo Pascal for education... its useless
[09:21:50] <Jymmm> Not really.

[09:22:09] <Jymmm> TurboCNC is pritten in Turbo Pascal
[09:22:15] <Jymmm> written
[09:22:15] <toastydeath> fortran is still used
[09:22:39] <toastydeath> esp for scientific modeling, because that's what LINPACK is written in
[09:22:46] <RyanS> I thought it was a dead language
[09:22:49] <Valen> decent cobol/fortran programmers can get good pay at banks
[09:22:59] <Valen> all their crap was written in 1970 in those
[09:23:08] <toastydeath> nah, fortran can be highly optimized because it's such a shitty language

[15:02:43] <tjb1> When its done cutting and should rapid 3" up, it just hums and then the next pierce screws up because it thinks it is 3" above and then trys to rapid down to .160 to probe and it doesnt turn out well...
[15:03:07] <tjb1> I need to adjust velocity and accel for the Z again but then changing that changes the probe distance
[15:03:54] <JT-Shop> I use a number input box for tip voltage

[16:57:38] <tjb1> Alright thanks pcw_home, I will be ordering one soon
[16:58:18] <pcw_home> Did you give up an you Arduino THC? I would think it would work fine +- some electrical noise/grounding issues (the THCAD is a very paranoid design -2500V isolation 500V overload capability on 10V input etc)
[16:59:28] <pcw_home> but an arduino with the righ input conditioning should do as well
[16:59:30] <tjb1> Yes I am having problems with it…not sure where at the moment. I moved it over to a dedicated board and can't monitor the serial any more so I am not sure what is going on but when activated the torch just continues to dive down
[17:00:41] <tjb1> I would rather make the computer watch the voltage also so I can set it within axis. My other plan was to use the G540 vfd to set the target voltage in the Arduino but at this point I am tired of playing with the Arduino
[17:01:08] <pcw_home> I suspect that ground bumping might be an issue, one solution would be to isolate the arduino (isolate the serial port)
[17:02:53] <pcw_home> both the plasma signal _and_ GND are liable to be noisy, so a floating voltage sense is better
[17:03:09] <tjb1> Well the thcad isnt that expensive and the component file doesnt differ much when using it and right now its running 2 programs and the arduino one always seems to muff up
[17:03:30] <tjb1> Im not too experience with electronics so I would rather just plug the plasma voltage into a board and let the computer do the work
[17:04:05] <pcw_home> I'm the anti-salesman
[17:07:18] <tjb1> Heh, I thought I found the problem when I tried to measure a resistor on the filter and couldn't measure it…killed it, so I switched it to another analog input still dives. Thought I loaded the wrong chip, went it loaded the thc program and put it back on still dives…no clue…gave up.
[17:09:35] <tjb1> I am going to switch the probe input to a limit when not probing so if it ever dives enough that will kill it
[17:09:56] <jthornton_> no need to do that

[19:32:16] <tom3p> the original idea with geda/eagle and hal was to make a visualization of the hal file, then to allow editing and saving.
[19:32:25] <tom3p> I stopped after reviewing a very long list of candidates because the initial idea was flawed.
[19:32:35] <tom3p> Its visual scope: Theres no simple way to view the entire .hal for say even a simple stepper and still see the individual components.
[19:32:42] <tom3p> Theres no simple way to see the components and still see the overall view. I suggest that using geda/eagle/pd/python-wxwidgets is ok to >>explain<< an idea, not a whole wiring diagram.
[19:32:43] <tom3p> and for explanation, any of the submitted approaches work well enuf.
[19:39:17] <pcw_home> for similar reasons, high level languages are much more popular for hardware design than schematics
[19:40:48] <tom3p> i was looking at (v)hdl to describe it
[19:43:12] <pcw_home> An intermediate approach (a smart HAL editor) would be nice
[19:43:14] <pcw_home> as would automating component instantiation/ simple math
[19:45:04] <pcw_home> math /logic
[19:46:11] <pcw_home> net foobar sig1 + sig2
[19:47:17] <tom3p> visual or text? ( the c pre-processor might do the 'macro' substituion )
[19:47:39] <jdh> or m4
[19:48:28] <pcw_home> text
[19:50:55] <pcw_home> HAL is parsed anyway, it seems some simple math and logic functions could be included
[19:51:23] <tom3p> macro expansion inside the hal parser
[19:52:28] <pcw_home> it would make some things easier to read (for me at least)
[19:53:59] <tom3p> thats the basic point, a hal file is difficult to imagine
[19:54:31] <tom3p> for me, its paper & pencil (with eraser) time
[19:55:31] <born2late> any1 has some nice icons for linuxcnc ?

[20:03:38] <tom3p> src code url included in desc
[20:09:20] <tom3p> one simple way to make hal more readable is a fortran like column approach
http://pastebin.com/EMwEDxD1
[20:09:56] <jdh> how is that fortran like?
[20:10:15] <tom3p> it ^^^ allows a visual grouping that normal text misses
[20:10:39] <tom3p> jdh: punch cards really, not fortran
[20:10:54] <jdh> I've only done cobol on punch cards :)
[20:11:10] <jdh> but, sadly, I do something fortran related at least once a week.
[20:12:50] <KimK> jdh: Great! We will be sure to consult with you when we get back around to the APT restoration project.
[20:13:19] <tom3p> well, if you want to pursue gui-hal, i suggest the most examples (available code) is in java. look at grasshopper for rhino
[20:13:50] <jdh> KimK: some things are best left in the past :)
[20:14:24] <KimK> jdh: Are you talking about Fortran or APT?
[20:14:30] <jdh> sure.
[20:14:57] <jdh> and if the answer to any problem is 'java', you are doomed.
[20:17:17] <tom3p> notice the graphical program
