[00:47:58] <XXCoder1> dunno
[00:48:17] <XXCoder1> what ya think? this is just X axis done, still figuring some stuff
https://dl.dropboxusercontent.com/u/53432577/cncidea.png
[00:48:44] <FrankZappa> decent sketch, but what does it represent
[00:48:55] <FrankZappa> two chamfered rails
[00:49:01] <XXCoder1> SBR20
[00:49:05] <FrankZappa> a platform with inverted c channels
[00:49:07] <XXCoder1> black one is ballscrew
[00:49:18] <CaptHindsight> I installed onto Xubuntu 12.04 and it's missing one of the RTAI modules
[00:49:22] * jdh ponders pointing out that ballscrews are round.
[00:49:31] <XXCoder1> ignore stuff floating nearby its parts I made but havent used
[00:50:05] <Connor> XXCoder1: Rotate the SBR20's 90 degrees.
[00:50:05] <CaptHindsight> polymer bearings?
[00:50:26] <XXCoder1> jdh: lol yeah its just same dimension as ends, screws is smaller so its accurate enough to figure if design will work
[00:50:55] <CaptHindsight> Connor: why rotate the bearings 90 deg so the supports are not as load bearing?
[00:51:35] <XXCoder1> sbr20 is riciously heavy for small cnc so on sides would work but bit more complex to make so meh
[00:52:05] <XXCoder1> I have yet to add front and back supports for surface. not sure how to design that yet
[00:52:05] -!- a_morale_ has quit [Read error: Connection reset by peer]
[00:52:06] <Connor> Because, He's using supported rails.. The gantry will cantilever and will cause the bearings to pull away from the rails..
[00:52:43] <Connor> the supported bearings he's using are only good for loads in 3 directions.
[00:53:13] <XXCoder1> https://dl.dropboxusercontent.com/u/53432577/CncRoughDraft.png rough draft, before I knew sizes
[00:53:13] <jdh> it appears to me that they are in the best orientation
[00:53:28] <jdh> but, that one isn
[00:53:31] <jdh> but, that one isn't
[00:53:46] <jdh> in that one, rotate them 90 degrees
[00:53:47] <Connor> That's the right way.
[00:54:17] <XXCoder1> sigh gonna run dinner time lol be back
[00:54:18] <jdh> hrm.
[00:54:19] <Connor> the gantry can't cantilever.. causing it to drag.
[00:54:19] <CaptHindsight> Connor: why do you feel that way?
[00:54:24] <jdh> I'd call that the wrong way.
[00:54:47] <CaptHindsight> please don't take this is as a criticism
[00:55:08] <Connor> Look at the way the bearings are made.. good for side to side and load directly toward the rail.
[00:55:23] <CaptHindsight> is the concern that the bearing blocks will spread open?
[00:55:44] <Connor> Yes. and, they're no bearing surface on the bottom part.. they drag.
[00:56:19] <CaptHindsight> are you sure that his blocks have no bearings on the lower parts?
[00:56:30] <CaptHindsight> thats just poor blocks
[00:56:33] <Connor> Non of those do..
[00:56:40] <Connor> TSK'S do.
[00:56:48] <Connor> but, not the round supported style.
[00:57:57] <Connor> I know this.. because I made mine the other way.. and have this exact problem.. the ONLY thing that saved me was using a 16mm ballscrew which helps take the load...
[00:58:12] <Connor> which is VERY bad design.. but works okay with lower load.

[00:59:20] <jdh> you are saying the rail with the support down is the worst way?
[00:59:36] <jdh> with the majority of the load being down?
[00:59:53] <Connor> Only when you have a gantry that can cause the back part of RISE.
[01:00:03] <CaptHindsight> if they have no bearings below the center of the bearing shaft
[01:00:06] <Connor> due to cantilever forces.
[01:00:13] <CaptHindsight> I've never seen any that cheap
[01:00:52] <Connor> You might have 1 below the shaft, but, on one side only..
[01:01:16] <jdh> surely that could be compensated for with better spread between the bearings
[01:01:19] <Connor> Would you try to run them with a load upside down ?
[01:02:04] <Connor> jdh: To some degree yes.. but, it has to be a rather large spread.

[01:14:31] <Connor> They're.. good shot.. you can clearly see only 1 circuit on the underside.
[01:15:34] <Connor> I think they normally only have 4 circuits in the 20's. and you loose one for the supported version..
[01:16:06] <Connor> but, the orientation isn't known till you get them.

[01:18:57] <jdh> I wonder how big that is. It isn't a lot more than a chinese 6040 with shipping
[01:19:35] <Connor> any upward force will cause the bearing to drag on one side.. and if significant force is applied, it could start to spread.. by rotating 90 degrees you can counter that because both sets of bearings will be working with each other.. and not dragging.

https://dl.dropboxusercontent.com/u/53432577/sbr20blockinside.jpg
[01:34:46] <Connor> BINGO
[01:34:56] <Connor> Only 3 circuits right ?
[01:35:02] <XXCoder1> 4
[01:35:28] <XXCoder1> left side is lower and harder to see
[01:37:17] <CaptHindsight> if it was only 3 circuits that lower left side would drag on the rail
[01:37:22] <Connor> If your gantry has ANY chance to provide some sort of cantilever force (I.E. apply upward force to the front or back of the gantry) rotate the bearings 90 degrees. IMHO
[01:38:07] <XXCoder1> well changing design to moving bed and fixed gantry might be better. definitely easier to make!
[01:38:14] -!- garfong has quit [Ping timeout: 265 seconds]
[01:38:33] <Connor> True.. but, at a cost of space.. depending on size of machine.
[01:38:56] <XXCoder1> remember my more recent design? longest dim is 600 mm or 2 ft or so
[01:39:10] <Connor> No. I don't.. Can't keep track.
[01:39:13] <Connor> :)
[01:39:25] <Connor> Have hard enough time keeping track of my stuff. :)
[01:40:18] <XXCoder1> https://dl.dropboxusercontent.com/u/53432577/cncidea.png
[01:40:39] <Connor> So, Is that just a table then ?
[01:40:45] <Connor> not the gantry ?
[01:41:14] <XXCoder1> yeah
[01:41:21] <XXCoder1> no y and z parts yet
[01:41:35] <Connor> fixed gantry.. having them mounted that way is fine.
[01:41:46] <XXCoder1> the table would be part of gantry but easy enough to change design
[01:41:58] <andypugh> XXCoder1: sketchup?
[01:42:06] <XXCoder1> nah freecad
[01:42:16] <XXCoder1> the rough draft one is sketchup
[01:42:25] <XXCoder1> I got sick with sketchup bad ui so I gave it up
[01:42:35] <andypugh> Ah, OK. I was wondering why your models look so unlike the real thing :-)
[01:44:16] <jdh> grabcad has lots of models of SBR & ballscrews.
[01:44:38] <XXCoder1> yeah one thing mystified me though
[01:44:48] <XXCoder1> freecad rotation just does not make sense at all.
[01:45:38] <andypugh> Alibre / Geomagic is a pretty good CAD package and not horribly expensive (Windows only, AFAIK) I don’t actually think that any of the Free or Linux packages are quite there, though I applaud their efforts.

[01:58:28] <andypugh> The pricing there is much more reasonable.

[02:19:30] <XXCoder1> For example, with a Angle of 15 : specifying, 1.0 for x and 2.0 for y, will rotate 15 and 30 in the y-axis and the x-axis
[02:19:38] <XXCoder1> it does NOT do that for me
[02:19:49] <zeeshan> yes cause youre using junk software!
[02:20:03] <XXCoder1> pay for good one for me then
[02:20:08] <zeeshan> fak paying for software
[02:20:09] <andypugh> rotating parts in Inventor is almost impossble. But why do you want to? You assemble them into assemblies instead.

[02:21:49] <zeeshan> then middle mouse button

[02:22:14] <XXCoder1> what software you think I am using?
[02:22:30] <zeeshan> i dunno what it is XXCoder1 but either it sucks or yuou dont know how to use it
[02:22:36] <zeeshan> if you're trying to rotate specifically at a standard angle
[02:22:41] <XXCoder1> then stop helping
[02:22:44] <zeeshan> thats pretty standard stuff you can expect.
[02:22:59] <XXCoder1> because actions you suggested? did nothing lol
[02:23:05] <zeeshan> stop being self righteous and download inventor
[02:23:08] <zeeshan> and use it for 30 days trial
[02:23:13] <zeeshan> and then pay $50 for the student license
[02:23:35] <zeeshan> andypugh: did the g thing work
[02:23:37] <zeeshan> is that what you want
[02:23:52] <zeeshan> i made a mistake in my instruction
[02:23:58] <zeeshan> is G then left mouse button not middle
[02:24:12] <zeeshan> middle mouse button will pan
[02:24:15] <zeeshan> (in that mode)
[02:24:44] <andypugh> zeeshan: Sorry, we seem to be confused. XXcoder is using (errr, I have forgotten) and finds exact part rotation hard. I am saying that xact part rotation is also hard in Inventor, but that is partly because it is rarely what you really want to be doing.
[02:25:09] <XXCoder1> freecad
[02:25:10] <zeeshan> i use part rotation to view a part at a specific angle
[02:25:14] <zeeshan> for an angle drilled hole
[02:25:18] <zeeshan> its nice to do
[02:25:23] <zeeshan> (compound angle)
[02:25:46] <andypugh> The exception, actually, is when you export the goemoetry to CAM software and actually wanted the origin somewhere else.

[02:30:09] <XXCoder1> I finally understand how fucking rotation works
[02:30:36] <XXCoder1> apparently part has orgin angle. I have to figure how rotate from that, so I would need to set it to zero rotation

[02:38:45] <zeeshan> the main reason ive used it in the past is cause carbon build up causes hot spots
[02:38:49] <zeeshan> which cause preignition
[02:39:25] <andypugh> Oh, you still use sparks?
[02:39:37] <ChuangTzu> lol
[02:39:39] <XXCoder1> sparkplugs?
[02:39:44] <ChuangTzu> diesel++
[02:40:05] <XXCoder1> glowplug lol (in fact someone used one to make printer head lol)
[02:41:13] <andypugh> ChuangTzu: Servo thermostat, rather than wax element.
[02:41:30] <XXCoder1> new and stupid kickstarter idea
[02:41:34] <XXCoder1> wax 3d printer
[02:41:50] <andypugh> What’s stupid aboue a wax printer
[02:41:52] <XXCoder1> make all that fancy candles LOL
[02:42:07] <XXCoder1> well and mold maker HMM didnt think of that
[02:42:32] <XXCoder1> if I recall some pour methods use lost wax?
[02:42:57] <andypugh> wax parts are ideal for then investment casting. It’s presumably for jewellers or anyone else who actually wants metal at the end of the process.
[02:43:45] <XXCoder1> about seafoam "Yeah I did this to the GEO and blacked out the sun with all the smoke Good way to **** the neighbors off "
[02:44:02] <andypugh> Though you can actually lost-wax cast with the normal filament. But maybe not add sprues and gates, or manually tweak the same way.
[02:44:37] <andypugh> Seafoam sounds more and more like Redex
[02:45:06] <XXCoder1> I might do engine fuel and oil but definitely not rest of it! oo risky to me lol

[02:57:46] <zeeshan> yep i have
[02:57:56] <XXCoder1> it turned to smoke bomb too?
[02:57:59] <zeeshan> hell yes
[02:58:06] <zeeshan> for 20 minutes. thick white smoke
[02:58:13] <zeeshan> you'll piss off your neighbours
[02:58:16] <XXCoder1> you did everything or just gas/oil?
[02:58:30] <zeeshan> fuel
[02:58:34] <zeeshan> + oil
[02:58:56] <zeeshan> i stuck my video camera into the hole
[02:59:04] <zeeshan> (sparkplugs) and the pistons were sexy after
[02:59:11] <zeeshan> no more black shit caked on em
[02:59:13] <XXCoder1> I wont bother with my ticking bomb but my next car I probably will
[02:59:35] <XXCoder1> oh yeah guy said my car engine mount are fucked. how easy to fix?
[02:59:45] <zeeshan> what car
[03:00:03] <XXCoder1> probably wont bother if it will work fine for another couple month, p1744 is far more serious problem for my car.
[03:00:20] <XXCoder1> ford contour 1998. last year with bad toque transformer that always overheat
[03:00:42] <zeeshan> haha
[03:00:44] <zeeshan> those are cool cars
[03:00:47] <zeeshan> my friend did a sho conversion
[03:00:57] <XXCoder1> what does sho comversion do?
[03:01:02] <zeeshan> different engine
[03:01:03] <zeeshan> more power
[03:01:17] <XXCoder1> lol woulodnt that make p1744 come sooner?
[03:01:26] <zeeshan> yea but we like power!
[03:01:32] <zeeshan> im looking at the engine bay pic
[03:01:35] <XXCoder1> lol
[03:01:35] <zeeshan> transverse mounted
[03:01:41] <zeeshan> which mount is busted? front rear left right
[03:01:46] <zeeshan> (drivers = left)
[03:01:54] <XXCoder1> guy was looking in from driver side
[03:02:15] <zeeshan> looks easy to change
[03:02:17] <zeeshan> its exposed right there
[03:02:42] <zeeshan> looks like 2 nuts that you loosen up to remove the bracket
[03:03:06] <XXCoder1> link tp pic?
[03:03:11] <zeeshan> http://i61.photobucket.com/albums/h41/generacerator/1998%20Ford%20Contour%20SVT/DSC08100.jpg
[03:03:30] <zeeshan> the drivers side one is the one im dtalkin about
[03:03:45] <zeeshan> the passenger side one is usually easy to change
[03:03:46] <zeeshan> same with front
[03:03:47] <XXCoder1> that looks 2000s
[03:03:48] <zeeshan> the rear is the hardest
[03:04:01] <XXCoder1> probably why its still running fine LOL
[03:04:08] <XXCoder1> cars lime mine is hard to find
[03:04:54] <zeeshan> ok back to machinig! :DP

[04:58:34] <CaptHindsight> stiffer the better
[04:58:48] <XXCoder1> okay its around foot tall, 2' 4" wide, and 5.8 in long
[04:59:30] <XXCoder1> sides will be double walled, seperated by inch or so with some supports between. would act like over 3 inches thick

[05:06:38] <XXCoder1> not much of a choice. it is as wide as it is long
[05:07:24] <XXCoder1> the longest dimestion, its width, is 2 ft and 6 in
[05:07:26] <CaptHindsight> that's the trade-off if you can't make the table travel
[05:07:34] <XXCoder1> one foot tall
[05:07:53] <XXCoder1> yeah I plan to make fixed gantry version when that ones done. to compare
[05:08:47] <CaptHindsight> bbl
[05:09:06] <XXCoder1> its height is uncertain, I can make it shorter if needed. less mass is nice too

[14:13:57] <CaptHindsight> trying to get this touch screen stable in 12.04 xubuntu, Linuxcnc starts up fine using the mouse every time. As soon as you use the touch screen it tries to start and freezes as the Axis window pops up
[14:14:43] <XXCoder1> bad driver?
[14:14:50] <XXCoder1> morning btw
[14:14:55] <CaptHindsight> the axis taskbar has (no file) in it when it freezes with just the screen background in the window
[14:15:19] <CaptHindsight> no info in the console and it doesn't have a crash report
[14:16:50] <XXCoder1> I dont get it, how you start program shouldnt matter
[14:17:06] <XXCoder1> try start linuxcnc by command line see if theres any strange issues that way too

[14:18:51] <XXCoder1> if you use touch screen before starting linuxcnc then use mouse to start linuxcnc does it load just fine?
[14:19:07] <CaptHindsight> the desktop icon starts linuxcnc in a console
[14:19:37] <CaptHindsight> it's start fine when using the mouse, in any order
[14:20:14] <CaptHindsight> I also added linuxcnc to the startup and it starts up fine every time

[14:42:52] <XXCoder1> yeah so if router move too fast while cutting in least one side would get correct load and other side, one being pulled up, would get 40%
[14:42:58] <CaptHindsight> If your bearing blocks don't have enough bearings don't use them
[14:43:58] <CaptHindsight> that pic ^^ shows the load capacity for SBR at 3 different orientations
[14:44:14] <CaptHindsight> with proper bearing blocks
[14:44:31] <XXCoder1> yeah thats what I was talking about with 40% and all :)

[16:47:50] <Jymmm> If I have a round object of unknown diameter, but I have the ability to draw/mark in the circumference 370 degrees (basically overlapping, much like wrapping a seamstress tape measure around your waist) is there a "scale" of sorts that can be universally known/used for marking on the object that can determine it's circumference? I'm thinking something degree related instead of actual length UOM.
[16:50:48] <zeeshan|2> Jymmm: instead of finding the cicumference like trhat
[16:50:59] <zeeshan|2> can you just find the diameter first and calculate cicumference?
[16:51:03] <Jymmm> no
[16:51:09] <zeeshan|2> cause if you can, then you can use find 2 chords
[16:51:17] <zeeshan|2> and know diameter and know cicumference
[16:51:40] <Jymmm> no

[16:52:32] <IchGuckLive> hi all B)
[16:52:40] <Jymmm> This is basically a 4th rotary axis, and need to also determine it's alignment, and the object's alignment too.
[16:52:42] <IchGuckLive> its rekordbraking hot here in germany
[16:53:23] <IchGuckLive> maZer`-: ?
[16:53:25] <Jymmm> I know this is a trig thing, I just don't know trig =)
[16:53:41] <zeeshan|2> oh i guess i didnt understand the problem
[16:53:49] <Jymmm> it's all good =)
[16:53:50] <zeeshan|2> you're saying you want to convert degree movements to cicumference?
[16:54:06] <Jymmm> in a sense, yes.
[16:54:10] <zeeshan|2> okay
[16:54:20] <Jymmm> but has to scale from ~1" to ~12"
[16:54:22] <zeeshan|2> http://www.mathwarehouse.com/trigonometry/radians/images/picture-s=r-theta-circle.gif
[16:54:27] <zeeshan|2> you can use arc length
[16:54:33] <zeeshan|2> as long as the center of rotation doesnt change
[16:54:46] <zeeshan|2> you can be confident that r theta gives you the cicumference
[16:55:09] <IchGuckLive> XXCoder1: did it move on auto g-code or still in the box
[16:55:16] <zeeshan|2> theta is in radians btw.
[16:55:17] <zeeshan|2> not degree
[16:55:21] <zeeshan|2> so you'll have to covnert it
[16:55:26] <XXCoder1> IchGuckLive: sorry what?
[16:55:31] <XXCoder1> and hey
[16:55:40] <IchGuckLive> [15:14:17] <XXCoder1> hell who knows my first cnc might work fine for long while lol
[16:55:41] <Jymmm> zeeshan|2: I have nfc what that other than pacman =)
[16:55:50] <Jymmm> ^is
[16:56:02] <zeeshan|2> r is the distance to whatever object youre measuring
[16:56:04] <XXCoder1> oh it was about my cnc thats currently in design
[16:56:09] <zeeshan|2> (i guess your rotary table radius)
[16:56:19] <zeeshan|2> theta is the degree ie 10 degrees converted to radians
[16:56:20] <Jymmm> zeeshan|2: and s ?
[16:56:31] <zeeshan|2> s is the arc length
[16:56:38] <IchGuckLive> XXCoder1: you will be the man of the year if you retch a runnning system
[16:56:46] <zeeshan|2> if you find s for 360 degrees, you would have cicumference

[16:57:09] <Jymmm> zeeshan|2: but the circumerfence is unknown
[16:57:09] <IchGuckLive> XXCoder1: idee 4
[16:57:18] <XXCoder1> it has couple problems, Z axis is too recessed for one but otherwise pretty good.
[16:57:26] <zeeshan|2> Jymmm: but angle is known
[16:57:38] <zeeshan|2> and im sure you know the radius of the rotary table
[16:57:51] <zeeshan|2> so if you jog your table 10 degrees
[16:57:52] <IchGuckLive> XXCoder1: sice you joint us i might have build in real about 30+ mashines here
[16:57:52] <XXCoder1> the curved boxes is SBR rails and black boxes is ballscrew (yes, i know its much thinner and round, its just general dimension)
[16:57:56] <Jymmm> zeeshan|2: 360 or 370
[16:57:59] <zeeshan|2> and your rotary table was 12
[16:58:09] <Jymmm> 12?
[16:58:15] <zeeshan|2> (in diameter)
[16:58:25] <Jymmm> zeeshan|2: No, I don't know that.
[16:58:37] <zeeshan|2> why not! :P
[16:58:56] <Jymmm> zeeshan|2: cause that's what I'm trying to determine *SMACK*
[16:59:01] <IchGuckLive> XXCoder1: budget from 150-6000
[16:59:14] <XXCoder1> lol cool. mines bit over 1k so far
[16:59:15] <zeeshan|2> you said you're trying to determine cicumference
[16:59:24] <Jymmm> Yes
[16:59:34] <XXCoder1> anyway gonna run, be bacjk
[16:59:47] <IchGuckLive> ;-)
[16:59:54] <zeeshan|2> diameter is different than cicumference! :P
[17:00:06] <Jymmm> yes
[17:00:20] <IchGuckLive> maZer`-: ?
[17:00:30] <Jymmm> zeeshan|2: the only consistancy is 360 degrees around.
[17:01:19] <Jymmm> zeeshan|2: If s from 0-45 is 1", from 45 to 270 it could be 6" for all I know
[17:01:40] <zeeshan|2> 1" is the distance from the center of the circle
[17:01:43] <zeeshan|2> to the object?
[17:02:00] <Jymmm> zeeshan|2: I need to take those two numbers and find the circumferance of the object.
[17:02:09] <zeeshan|2> oh
[17:02:19] -!- thomaslindstr_m has quit [Quit: Leaving...]
[17:03:04] <zeeshan|2> if that is the same object
[17:03:15] <zeeshan|2> then you can use either one of those information
[17:03:26] <zeeshan|2> to find out the the 'r' in the s = r * theta formula
[17:03:37] <zeeshan|2> and then just do s = the known r * 360
[17:03:41] <zeeshan|2> to get cicumference
[17:03:54] <Jymmm> zeeshan|2: I need the formula long hand
[17:04:08] <zeeshan|2> you gotta tel lme what 1" is first
[17:04:08] <Jymmm> algabric notation
[17:04:21] <Jymmm> zeeshan|2: it's unknown
[17:04:53] <zeeshan|2> you need to know either how far the object is from the center of the circular rotation
[17:04:56] <Jymmm> 1" is the arc length fro 0 to 45 degrees
[17:05:07] <zeeshan|2> or the arc length the object moves during that angular movement
[17:05:18] <Jymmm> 4" is the arc length from 45 to 270 degrees.
[17:05:20] <zeeshan|2> to determine the cicuferemce
[17:05:35] <Jymmm> what is the circumference?
[17:06:20] <zeeshan|2> arc length (s) = radial distance to object from center (r) * angular movement (theta)
[17:06:54] <Jymmm> Yeah, doesnt' help me in the least unless it's long hand
[17:06:58] -!- amiri has quit [Ping timeout: 240 seconds]
[17:07:22] <Jymmm> all I can do is determine the degree of rotation on a round object.
[17:07:41] <zeeshan|2> r = s/theta = 1" / (45*pi/180)
[17:07:49] <zeeshan|2> the pi/180 is converting degrees to radians
[17:07:58] <Jymmm> what is theta?
[17:08:06] <zeeshan|2> 45
[17:08:17] <zeeshan|2> the angular distance you moved
[17:08:22] <Jymmm> ok
[17:08:26] <zeeshan|2> in the case of 45 to 270
[17:08:27] <zeeshan|2> it'd be
[17:08:36] <zeeshan|2> 270-45 = 225
[17:08:54] <zeeshan|2> so when you solve this equation r = s/theta = 1" / (45*pi/180)
[17:09:02] <zeeshan|2> you get r = .785398
[17:09:45] <IchGuckLive> zeeshan|2: what is the overall goal to meet this calculations
[17:10:39] <zeeshan|2> IchGuckLive: one sec
[17:10:42] <zeeshan|2> so since now you know r
[17:10:55] <zeeshan|2> you can do cicumference = 2*pi*radius
[17:11:19] <zeeshan|2> which just comes from the formula s = r * theta = r * 360*pi/180
[17:11:27] <zeeshan|2> since there are 360 degrees in a full rotation
[17:11:36] <zeeshan|2> i hope it makes sense =/
[17:12:12] <zeeshan|2> IchGuckLive: i think he knows angular movement and how much the object moves in the arc path
[17:12:18] <zeeshan|2> and he needs to know cicumference based on that
[17:12:22] <CaptHindsight> guess I'm stuck with Unity since the touchcsreen problem doesn't happen there, only in XFCE

[17:29:20] <zeeshan|2> what do you mean by 'tell it to mark on the object 360 degrees.'
[17:30:51] <Jymmm> To give the operator a reference point
[17:31:16] <Jymmm> of where 180 degrees is on the object
[17:31:35] <zeeshan|2> it seems like you have all the angular information

[17:48:56] <zeeshan|2> :D

[17:53:06] <ChuangTzu> do you bolt that to a part and then do an optical alignment to the faces?

[18:13:18] <maZer`-> is there a way to couple a input pin of mesa to m-command?
[18:14:47] <Deejay> hi mazer
[18:15:34] <maZer`-> hi Deejay :D
[18:15:53] <cpresser> maZer`-: there are custom-m-codes. M101 and so on
[18:16:22] -!- zlog has quit [Remote host closed the connection]
[18:16:23] <cpresser> maZer`-: you cann assign them a simple shell-script which does a 'halcmd setp <mesa-pin> <value>'
[18:16:27] -!- Tom_itx has quit []
[18:16:57] <maZer`-> oh very nice :D
[18:17:14] <maZer`-> also i did a custom script for the m command
[18:17:19] <archivist> he said input pin
[18:17:24] <maZer`-> my command called m160
[18:17:38] <maZer`-> and now i want to do if input pin pressed execute m160
[18:18:05] <cpresser> ah sorry, didnt read everything :/
[18:18:10] <maZer`-> no problem :D
[18:18:22] <maZer`-> or is there a way to do if pin pressed execute command? :D
[18:18:27] <maZer`-> i mean execute shell script? :D
[18:18:54] <cpresser> depends. when in MDI mode you can use halui.mdi-command
[18:19:48] <maZer`-> at the moment im a really n00b, im not really know when im in mdi mode ! :D
[18:20:13] <maZer`-> if a g-code programm is running then im not in mdi mode ? :D
[18:20:16] <cpresser> basically: auto-mode= when a gcode-programm is running. mdi-mode otherwise
[18:20:35] <maZer`-> ahh ok :(
[18:20:42] <cpresser> what does your M160 do?
[18:20:43] <maZer`-> also it should work twice :D
[18:20:53] <maZer`-> m160 release the tool from machine
[18:20:58] <maZer`-> and m161 fix tool to machine
[18:21:45] -!- Tom_itx [Tom_itx!~Tl@unaffiliated/toml/x-013812] has joined #linuxcnc

[18:22:17] <cpresser> then i dont see any use for it in auto-mode!?
[18:23:00] <maZer`-> yes but, if the g-code is requesting another tool i want that machine drives to a point and waiting until i change tool :(
[18:23:14] <XXCoder1> whoo
[18:23:21] <maZer`-> but thats another problem :d
[18:23:22] <XXCoder1> my car is so much better after antilock
[18:24:00] <cpresser> then dont implement that stuff as a M-Code. use semi-automatic toolchanging.
http://linuxcnc.org/docs/html/hal/hal-examples.html
[18:24:07] <XXCoder1> I really took it out of town with very hard acceration that took rpm to 6k (redline 7k, I normally never even reach 3k)
[18:24:47] <XXCoder1> no errors. :) heres hoping it runs fine for month or 21
[18:24:49] <XXCoder1> 2
[18:25:14] <maZer`-> cpresser ahh sounds very nice :D
[18:26:28] <maZer`-> cpresser but i need the pin to change tool for this too
[18:27:57] <maZer`-> is there a way to bind a pin directly to a shell script? :D
[18:28:03] <cpresser> you can use a 'or' component for that. if either iocontrol (M6) or you (Button) requests a tool-change -> release the clamp
[18:28:53] <maZer`-> yes ok

[21:02:49] <Loetmichel> which material is that? Ti?

[21:03:09] <Loetmichel> or simple cast iron?
[21:03:12] <XXCoder> or was it Si? forgot :P
[21:05:04] <Loetmichel> seems to be very brittle
[21:05:26] <humble_sea_bass> yuh. lots of chipping
[21:06:24] <Loetmichel> i can remeber turning steels where i had to hook into the swarf with a hook and run across the company

[21:50:02] <XXCoder> easy enough to modify gantry width from 248 mm to 240 mm to make z screws and blocks past gantry walls
[21:50:26] <Loetmichel> XXCoder: i dont liket the desings where the machine table is "levitating" above the y rails
[21:50:38] <XXCoder> its not
[21:50:42] <XXCoder> its supported at ends
[21:50:43] <Loetmichel> i am more for a design with two y rails
[21:50:51] <Loetmichel> grrr
[21:50:55] <Loetmichel> i meant in between that
[21:51:15] <XXCoder> oh I dont see how to support work surface otherwise?
[21:51:31] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=11205
[21:51:34] <Loetmichel> this way
[21:51:50] <Loetmichel> use two y spindles and connect them
[21:52:01] <Loetmichel> so you can omit the bar underneath
[21:52:13] <XXCoder> I only have one X axis screw
[21:52:27] <Loetmichel> buy a second?
[21:52:32] <XXCoder> well
[21:52:44] <XXCoder> would also mnean I have to buy other nema 23
[21:52:54] <Loetmichel> but do as you please, i dint want to call you names, just wanted to give advice
[21:52:56] <XXCoder> can them be connected together or do I have to add something
[21:53:23] <Loetmichel> the big box that is the work surface on "my" machines makes the machine MUCH stiffer
[21:53:39] <XXCoder> yeah my design do have bit issue
[21:53:44] <XXCoder> gantry is extremely stiff
[21:53:49] <XXCoder> work surface not so much
[21:53:55] <Loetmichel> that is what i meant
[21:54:16] <Loetmichel> i see the caveats at work every day because boss only paid for a CNC 6040
[21:54:25] <Loetmichel> whcih has the same design flaw
[21:55:00] <XXCoder> well I did plan to add yet another wood surface on top of that one
[21:55:01] <Loetmichel> btw: the one screw in y has also the ptoblem that the gantry can tilt more or less easily
[21:55:03] <XXCoder> surifical one
[21:55:38] <XXCoder> even with SBR20 rails?
[21:55:48] <Loetmichel> if you have two screws left and right connected by a timing belt there is NO way that the gantry can get out of alignment
[21:56:11] <Loetmichel> depends more or less on the distance of the bearing blocks on the rails
[21:56:56] <Loetmichel> the "deeper" the gantry sides are the less the chance of forces pushing it out of 90°
[21:57:34] <XXCoder> unfortunately my budget is extremely locked down now :(
[21:57:52] <Loetmichel> have youi seen my photo?
[21:57:55] <XXCoder> even with recent anti-lock addon that really helepd my car tranmission, it still has serious problems
[21:57:57] <XXCoder> yeah
[21:58:20] <Jymmm> XXCoder: Don't eat, you could lose a few pounds anyway.
[21:58:47] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=11172
[21:58:48] <XXCoder> lol
[21:59:00] <Loetmichel> there you can see the belt at the back that connects the two screws
[21:59:07] <Jymmm> XXCoder: And walk to work, thaty'll save on gas, as well as wear and tear
[21:59:10] <Loetmichel> (not mounted yet)
[21:59:32] <XXCoder> Jymmm: forget that. 32 min drive means 640 min walk :P
[21:59:38] <XXCoder> I see it
[21:59:48] <Jymmm> XXCoder: GIT ER DONE!
[22:00:26] <Loetmichel> on my old machine i did that a bit more sophisticated then necesssary

[22:00:59] <XXCoder> fancy lol
[22:01:34] <Jymmm> Loetmichel: what is it?
[22:02:01] <Loetmichel> Jymmm: connectng belt for the two y spindles
[22:02:05] <Loetmichel> connecting
[22:02:13] <Jymmm> ah
[22:02:28] <Loetmichel> on the back of the machine
[22:02:41] <Loetmichel> on the front there are 2 steppers wiht short belts
[22:03:01] <XXCoder> loet good thing I can get unlimited scrap wood from work
[22:03:07] <XXCoder> and they throw a LOT away
[22:03:18] <XXCoder> so I can get it to riciously thick table
[22:03:19] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=4403&g2_imageViewsIndex=1
[22:03:32] <XXCoder> 5 inches thick. why not? Just rise gantry a bit
[22:03:37] <Loetmichel> thats the front of that machine
[22:04:17] <XXCoder> so only one err I guess nema 34 on both screws
[22:04:41] <Loetmichel> no
[22:04:44] <Loetmichel> two
[22:04:53] <XXCoder> wired together?
[22:05:00] <Loetmichel> 50mm square, is that 34?
[22:05:19] <Loetmichel> no, 2 stepper drivers wired to the same step/dir inputs
[22:05:38] <Loetmichel> thats why that electronics bloch in the middle has 4 cards ;-)
[22:05:38] <XXCoder> thats what I meant :) one controller output to 2 motors
[22:06:11] <XXCoder> I dont have seperate drivers, the controller drives em directly
[22:06:21] <XXCoder> cheap one lol
[22:06:37] <XXCoder> 50mm is approx 2 in
[22:06:48] <XXCoder> nema 23?
[22:06:58] <XXCoder> that'd be 2.3 inch though so dunno
[22:07:16] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=4585&g2_imageViewsIndex=1
[22:07:27] <Loetmichel> there you can see the stepper(s)
[22:07:37] <Loetmichel> (please ignore my chaos) ;-)
[22:07:39] <XXCoder> it looks large enough to be 34
[22:07:56] <XXCoder> double side shaft I see
[22:08:12] <Loetmichel> the mounting screws are 50mm square
[22:08:59] <Loetmichel> searching, moment
[22:09:47] <XXCoder> oh I got X and Y axis mixed up or maybe thats just culture thing lol
[22:10:14] <Loetmichel> http://www.mechapro.de/shop/Schrittmotoren/Schrittmotor-Oriental-Motor-PK268-E3-0B::94.html
[22:10:17] <Loetmichel> got them
[22:10:33] <Loetmichel> no, x and y depends on where you are sitting
[22:11:03] <Loetmichel> if you are sitting on the smaller side "in front" the gantry moves in y.
[22:11:09] <XXCoder> I always thought the table axis is always X, gantry side to side Y, z is up and down
[22:11:18] <Loetmichel> if you sit on the long side the gantry moves in x
[22:11:58] <Loetmichel> like companys machine:
http://www.cyrom.org/palbum/main.php?g2_itemId=14148
[22:12:39] <Loetmichel> x0y0 is on your left hand towards you. every time
[22:13:01] <XXCoder> it says 56 mm thats near 2.3 inches so nema 23. interesting
[22:13:07] <Loetmichel> so if you operate the maschine from the long side-> gantry moves in x.
[22:13:49] <XXCoder> isnt that fixed in cnc settings
[22:14:12] <Loetmichel> yeah, according to your point of view ;-)
[22:14:23] <XXCoder> cool
[22:15:12] <XXCoder> from what i figure best way is to just make table thicker. its first cnc, not expecting perfection
[22:15:29] <XXCoder> I already plan 2 sheets but could do 3
[22:15:34] <Loetmichel> yeah, htat is a way to do it
[22:15:43] <Loetmichel> but please dont make it solid
[22:15:53] <Loetmichel> that will be unnecessary heavy
[22:15:58] <XXCoder> makes sense
[22:15:59] <Loetmichel> make a sandwich
[22:16:03] <XXCoder> yummy
[22:16:20] <XXCoder> so sheet, some number of wood planks, then sheet again
[22:16:22] <Loetmichel> which looks this way inside:
http://www.cyrom.org/palbum/main.php?g2_itemId=4053
[22:16:26] <XXCoder> adjusting for flatness would be fun
[22:16:27] <Loetmichel> yes
[22:16:37] <XXCoder> brb a sec
[22:16:44] <Loetmichel> let tha machine do that for you ;-)
[22:18:18] <Loetmichel> btw: here you can see the first day of building lilalinx' machine:
http://www.cyrom.org/pce/Lilafraese_tag1.avi
[22:18:29] <Loetmichel> (should put that up to youtube some day)
[22:20:03] <XXCoder> hmm lol ok. should adjust to pretty close first though
[22:20:17] <XXCoder> dont wanna see hgalf gone by done lol
[22:20:25] <XXCoder> saw that video. nice

[22:22:00] <Loetmichel> ... one cig, next cig, another one... i was smoking way to much then ;)
[22:23:01] <XXCoder> probably so bad if you happenjed not to have one, they would accuse you of pretending to be... you? ;)

[22:24:21] <Loetmichel> i have switched to e-cigs last october. so far: not one "real" one since then ;-)
[22:24:47] <Loetmichel> my wife appreciates ;-)
[22:28:15] <t12> there seems to be a whole industry of high dollar shop built e-cigs
[22:28:23] <t12> people paying like 500+ usd for fancy ones
[22:28:37] <XXCoder> lol
[22:28:42] <XXCoder> any homebrews? :P
[22:28:54] <XXCoder> probabky needs wheels ;)

[22:40:26] <t12> my absurdist taig lathe is finally coming along
[22:40:42] <ChuangTzu> what's absurdist abou tit
[22:41:47] <t12> the amount of crap being attached to 500 dollars of lathe
[22:41:57] <t12> eventually there will be no more orig parts left
[22:42:04] <ChuangTzu> heh
[22:42:27] <t12> https://vimeo.com/97622268
[22:42:33] <t12> ignore terrible untuned servo sound
[22:42:40] <t12> https://vimeo.com/97622267
[22:43:17] <t12> 400W mitsu servo seems to keep up quite well

[22:44:19] <Loetmichel> *siiiing*
[22:44:33] <t12> maybe has more to do with poor alignment
[22:44:36] <t12> will find out
[22:44:46] <XXCoder> 500 buck lol
[22:44:51] -!- maZer`- has quit [Read error: Connection reset by peer]
[22:44:57] <t12> maybe i should just stick with the mitsu controller cause of the adaptive tuning and such
[22:45:37] <XXCoder> why not use spidle not stepper for rotation?
[22:46:06] <Loetmichel> XXCoder: probably because steppers are less powerful and SLOW
[22:46:26] <XXCoder> exactly why I suggested it ;)
[22:46:29] <XXCoder> spidle

[22:46:46] <t12> next is figuring out all the ballscrew stuff
[22:46:57] <Loetmichel> XXCoder: i did threads on the chinese cnc6040
[22:47:07] <t12> the cross slide ballscrew is going to suck

[22:47:31] <Loetmichel> ... thakes a while, though
[22:47:32] <Loetmichel> ;-)
[22:47:35] <Loetmichel> -h
[22:48:22] <ChuangTzu> nice use of an optical breadboaqrd
[22:48:23] <ChuangTzu> -q
[22:48:24] <ChuangTzu> :)
[22:48:28] <t12> hahah
[22:48:33] <XXCoder> CRT driver apparently
http://tubetime.us/?p=173
[22:48:36] <t12> seemd to be the cheapest way to get a nice flat board
[22:48:47] <t12> also lots of random thorlabs parts to use at work
[22:48:48] <XXCoder> click astroid mini arcade to see it running
[22:50:11] <ChuangTzu> what the hell is with that video of you picking up a pile of cash?
[22:50:18] <t12> lol
[22:50:27] <t12> not me!
[22:50:42] <t12> boss always jokes about the machine printing money
[22:50:47] <ChuangTzu> lol
[22:50:51] <ChuangTzu> whaqt does the machine do
[22:50:54] <ChuangTzu> besdies print money

[22:50:59] <t12> laser catapult ejector
[22:51:00] <ChuangTzu> -q
[22:51:16] <t12> i prolly shouldnt have that video public heh
[22:51:16] <ChuangTzu> what's a laser catapault ejector?
[22:51:41] <t12> orig it was for tissue selection
[22:51:50] <t12> confocally focus a laser through microscope objective
[22:52:03] <t12> and you can knock cells off a slide onto a collection plate
[22:52:10] <ChuangTzu> with the laser?
[22:52:13] <t12> yeah
[22:52:22] <t12> orig it was stuff like grow a sheet of cells
[22:52:31] -!- a_morale [a_morale!~quassel@2-227-115-13.ip186.fastwebnet.it] has joined #linuxcnc
[22:52:34] <t12> find a way to tag or identify specific kinds of cells your looking for
[22:52:36] <t12> and use that to select them
[22:53:00] <ChuangTzu> are the cells on the bottom of the slide?
[22:53:06] <t12> in our case its beads
[22:53:07] <t12> but yeah
[22:53:51] <ChuangTzu> laser scans the plates until it finds a bead and then sends pulse that vaporizes a thin layer between the cell and the slide which makes it pop off?
[22:53:53] <t12> theres commecial systems that do this really well
[22:54:09] <t12> http://www.zeiss.com/microscopy/en_us/products/laser-microdissection/microbeam.html
[22:54:36] <t12> more generally the laser is fixed
[22:54:39] <t12> and you just move the slide around
[22:54:52] <ChuangTzu> yeah
[22:55:10] <t12> and the selection is out of band like via fluorescence
[22:55:25] <t12> the laser is steerable actually but it ends up not mattering
[22:55:40] <t12> the motion of whatever you collect into is the limiting factor it turns out
[22:55:47] <t12> so no point in steering the beam around
[22:56:00] -!- dybskiy has quit [Ping timeout: 260 seconds]
[22:56:08] <ChuangTzu> yeah
[22:56:55] <t12> it seems like it wouldnt be that reliable but it works really well
[22:56:58] <t12> cells survive and such
[22:57:09] <t12> ejection cone is very well defined
[22:58:25] <ChuangTzu> is that your brain?
[22:58:34] <t12> ya
[22:58:41] <t12> brains look gross
[22:59:18] <ChuangTzu> did it have a problem or was that just for fun?
[22:59:22] <t12> for fun
