[00:37:43] <PetefromTn_> Damn that Calzone was yummy but now I am gonna pay for it LOL...
[00:47:24] <norias> lol
[00:48:46] <PetefromTn_> I swear I am looking for a 4x4 suv right now and I want a manual tranny.....THERE ARE NONE!! Doesn't anyone drive stick shifts anymore?
[00:49:15] <malcom2073> Jeep!
[00:49:23] <malcom2073> Jeep Cherokees came with standards
[00:49:59] <PetefromTn_> I know right.... I think those are good trucks but not a big fan myself.
[00:50:24] <malcom2073> I've had a couple late 80's early 90's
[00:50:44] <PetefromTn_> they make a good crawler
[00:50:59] <malcom2073> Do really good for delivering pizza's in the snow too :-D
[00:52:33] <norias> hmm
[00:52:52] <norias> i don't think i'd buy a post-2003 suv
[00:52:54] <norias> myself
[00:53:06] <PetefromTn_> http://i.imgur.com/tuBM2jA.jpg thinking about an Xterra maybe....
[00:53:07] <norias> well, maybe a suburban
[00:53:10] <malcom2073> I got a 2004, and I'm fairly convinced I'll never get anything newer
[00:53:18] <malcom2073> Expedition
[00:53:47] <norias> does that xterra have a ladder frame?
[00:54:00] <norias> it's probably silly, but i like my trucks and suv's to have a ladder frame

[00:55:00] <PetefromTn_> yeah I believe it does
[00:55:47] <PetefromTn_> http://i666.photobucket.com/albums/vv22/JSPalmieri/Xterra%20Modifications/IMG_2170.jpg I drove one while looking at used car lots the other day.. it was pretty nice really I thought
[00:56:40] <PetefromTn_> they made them with 5 speed 4x4 but finding one is not looking too easy. Everyone I see is a soccer mom automatic and lots of 2wd models
[00:56:49] <norias> heh
[00:57:00] <norias> i like GM products
[00:57:11] <norias> because the suv's are made by the truck division
[00:58:05] <PetefromTn_> yep
[00:58:40] <norias> i worked with a guy who did a good stint at GM as an engineer
[00:59:06] <norias> explained that the truck division has a team per vehicle / platform
[00:59:28] <norias> whereas the car division has a body team per vehicle
[00:59:41] <norias> and a drivetrain team that covers several vehicles
[00:59:55] <norias> so, if you are in the body team, it's really hard to get drivetrain changes
[00:59:59] <zeeshan|2> aventtini: hi
[01:00:06] <norias> you have to design the body around what they give you
[01:00:11] <norias> but in the truck division
[01:00:22] <norias> if an enginer bolt will be hard to reach or whatever
[01:00:29] <norias> it's easy to ask to get it moved

[02:37:03] <furrywolf> meh. I'm not happy with the crosshatch I got, but I don't want to hone more and take off too much metal.
[02:37:36] <furrywolf> the dingleberry hone is not nearly as nice as the claims. to be effective, it really needs some type of cylinder the size of the bore mounted above and below the engine's cylinder.
[02:38:53] <furrywolf> if you keep the brush inside the bore, you get a sinusoidal shape, especially at the ends of the bore. if you remove the brush partway from the bore on the ends of the stroke, it completely fucks up the lip where the head gasket needs to seat. if you remove it entirely from the bore, in addition to fucking up the lip even worse, it bends trying to go back in.
[02:39:54] <furrywolf> not pleased with the result at all. I only have a crosshatch in the middle of the cylinder, and the lip is fucked up.
[02:40:57] <roycroft> i prefer the hones that have a number of straight stones spring mounted parallel to the sides of the cylinder
[02:41:02] <furrywolf> and it dumps tons of grit down in the block. much worse than a 3-stone hone.
[02:41:15] <roycroft> those ones with all the little balls always struck me as pretty wonky, at best
[02:41:21] <furrywolf> roycroft: yeah, I have one of those, but everyone said "no, those are evil, get a ball hone!"...
[02:41:38] <roycroft> so what you're saying is that i'm not everybody
[02:42:17] <furrywolf> correct. because you didn't chime in either of the times I asked about it, or add to any of the web sites or forum posts I found. :P
[02:42:26] <roycroft> i wasn't around
[02:42:36] <roycroft> you should have waited :P
[02:43:13] <roycroft> so hopefully you've gone back with a proper hone and fixed it
[02:43:15] <furrywolf> if you had same-diameter cylinders on either end of the engine's cylinder to keep the balls contained, I think it'd leave an excellent finish, quickly.
[02:43:25] <roycroft> mayhap
[02:43:43] <roycroft> but i would posit that having to install those other cylinders would be a significant drawback
[02:43:56] <roycroft> that far outweighs any possible advantage of using the little ball thing in the first place
[02:44:07] <furrywolf> it's not fixable. heh. the lip is worn, and the 3-stone hones have the problem with sinusoidal shapes as well...
[02:44:18] <roycroft> what problem does the straight stone hone have that the ball hone addresses?
[02:45:21] <furrywolf> less tolerant of poor alignment between your handheld drill and the bore
[02:45:39] <roycroft> so the ball hone is a tool for the unskilled
[02:45:57] <roycroft> that produces the finish of the unskilled
[02:46:04] <furrywolf> and those kneeling in a muddy driveway, like me. :P
[02:46:20] <furrywolf> where doing anything square is hard
[02:46:45] <roycroft> i've never used a ball hone
[02:46:53] <furrywolf> I've used one once! :P
[02:46:54] <roycroft> so i can't speak from experience
[02:47:06] <roycroft> but i always thought it would be suboptimal
[02:47:22] <roycroft> your experience does nothing but underscore that notion
[02:47:43] <furrywolf> the biggest problem is when the balls leave the bore, they fuck up the lip when you push it back in
[02:47:57] <furrywolf> they concentrate stress strongly on that lip and chew it up
[02:47:58] <roycroft> yes, i can see that happening
[02:48:12] <roycroft> your lip turns into a rough chamfer
[02:48:21] <Valen> are you meant to push it back in under power?
[02:48:25] <furrywolf> while the straight stones, as long as you don't let more than a third of the length out, won't do that.
[02:48:30] <furrywolf> Valen: yes
[02:49:09] <furrywolf> Valen: you want to have the stones travelling at a 45 degree angle to the bore, so you have to stroke it in and out at the same speed as the surface rotation speed...
[02:49:41] <Valen> I figured start in the middle, pull it out, start in the middle again, in reverse then pull out
[02:49:54] <roycroft> i'll continue to not use a ball hone
[02:49:59] <Valen> won't do wonders for your bore though I guess
[02:50:09] <furrywolf> you never want to run it in or out without it rotating, because that creates vertical marks, which are extra-bad.
[02:50:23] <roycroft> they cause oil gushes
[02:50:25] <Valen> ahh
[02:50:37] <Valen> start out the bottom of the block with it spinning
[02:50:45] <Valen> then pull up through in one direction
[02:50:55] <Valen> re start it with it in reverse
[02:50:58] <furrywolf> and how do you get it back down? :)
[02:51:15] <furrywolf> with a small engine, there's not enough room to feed the brush in through the bottom.
[02:51:16] <roycroft> by throwing it away and replacing it with a proper hone :)
[02:51:29] <roycroft> well
[02:51:30] <roycroft> better yet
[02:51:37] <Valen> see I'll just take mine to the engine guy who I do computers for ;->
[02:51:40] <roycroft> sell it on ebay as "vintage" for 2x what you paid for it
[02:52:34] <furrywolf> Valen: shops are very expensive.
[02:52:52] <furrywolf> bbl, back to cleaning the crap out of the block.
[02:52:52] <Valen> yeah, I need to do my engine
[02:53:01] <Valen> but I have nowhere to do it
[02:53:05] <Valen> :-<

[04:15:21] <toastyde2th> has anyone in here worked on the motion control part of linuxcnc
[04:15:47] <alex4nder> do you mean actual control, or the planning for the control?
[04:16:17] <furrywolf> Ask an actual question. :)
[04:16:22] <toastyde2th> specifically the planning for the control
[04:16:28] <toastyde2th> I was curious what it does
[04:16:48] <alex4nder> I'd suggest reading a lot of source
[04:17:43] <toastyde2th> that seems like a huge amount of investment to determine a rather quick answer, there's not a ton of different ways to do a motion planner
[04:18:11] <alex4nder> you haven't asked any questions
[04:18:17] <toastyde2th> okay, thanks.
[04:18:27] <alex4nder> you're welcome.
[04:20:12] <toastyde2th> Jymmm, cradek do you have a 10 second rundown on how the motion planner works in linuxcnc, I'm trying to compare it to how fourth derivative controls plan motion

[04:40:21] <furrywolf> I have the pesky belief that killing people is, you know, murder.
[04:40:43] <furrywolf> and assisting any agency that works towards same is thus wrong.
[04:40:46] <norias> sorry to hear that
[04:40:57] <norias> you probably wouldn't like me much
[04:41:11] <norias> murder is unlawful killing
[04:42:49] <furrywolf> unlawful, like various international bodies declared the last war we started?

[13:57:45] <Computer_barf> are steppers bound by a certain number of steps per rev or is that more of a driver thing?
[13:58:57] <Computer_barf> currently I have my steps per rev set to 2000, with my driver's dip switches set to that
[14:02:17] <malcom2073> They have a certain number of steps per revolution, that's how they're built
[14:02:27] <malcom2073> the number dependson the stepper, but most motion control steppers are 200 steps per rev
[14:02:30] <skunkworks> normal steppers are 200 full steps per rev. So you have 10X microstepping.
[14:02:32] <Roguish> Computer_baf: it's both. http://homepage.cs.uiowa.edu/~jones/step/
[14:02:38] <pcw_home> 1.8 degree motors have 50 poles and 200 full steps (this is determined by the motor design)
[14:02:39] <pcw_home> you can have an arbitrarily high number of fractional steps per whole step
[14:03:10] <pcw_home> though > say 32 you get into diminishing returns
[14:06:10] <Computer_barf> Ok so what I get from that is that I probably shouldn't have my driver set to 2000 steps and I should instead switch the dip switches to have it configured for 200, then i would also need to alter
[14:06:43] <Computer_barf> my ini's scale to reflect that, in context to my c7 ballscrews mm/rev
[14:07:11] <pcw_home> no I would set it for say 6400 steps (32 u steps)
[14:07:22] <pcw_home> full stepping is nasty
[14:08:14] <pcw_home> lots of vibration and likelihood of resonance stalls
[14:08:48] <skunkworks> well - software stepping? That may limit your ustepping - may have to balance what you can do.
[14:09:50] <Computer_barf> ahh. ok , I will do that, PCW, so i guess there is a certain number of microsteps per step and thats why you end up with the bigger number?
[14:10:01] <pcw_home> this is hardware (though you need to check your drives minimum step length and space as this may also limit the maximum ustep ratio you can use)
[14:13:24] <pcw_home> yes think of a compass needle with a magnet pulling it around in a circle (the compass needle is the step motor rotor)
[14:13:25] <pcw_home> the ustep ratio is determines the angular step size of the magnet (full steps are 90 degrees)
[14:15:34] <pcw_home> note that the compass needle torque vs displacement does not change, just the angular step size of the external field
[14:18:19] <pcw_home> and just like the compass with a 90 degree step in the field, with a full step (1.8 degrees),
[14:18:21] <pcw_home> the step motor rotor will jump to the next position and then overshoot and oscillate
[14:18:31] <pcw_home> (ring)
[14:20:22] <pcw_home> so the main advantage of large ustep ratios is that they are smoother and dont tend to excite
[14:20:24] <pcw_home> vibrations and possible resonances that can lead to step loss or stalls

[14:26:48] <_methods> http://www.micromo.com/microstepping-myths-and-realities
[14:30:02] <pcw_home> Ugg.. that paper has confused thousands of people into thinking ustepping results in lower torque
[14:30:29] <Rab> I'm one of them! :O
[14:31:30] <Rab> Can you clarify?
[14:32:54] <pcw_home> u-stepping does _not_ reduce the stall torque
[14:33:29] <pcw_home> (well it may be a bit lower than 1/2 stepping buts thats too nasty to use)
[14:34:22] <pcw_home> I dont think people understand what they mean by incremental torque
[14:35:02] -!- b_b has quit [Changing host]
[14:35:09] <pcw_home> ustepping does not magically change the torque vs displacement curve of the motor (that is a constant)
[14:36:31] <pcw_home> all it does is make the steps in rotating magnetic field angle smaller
[14:47:56] <_methods> so that paper is total BS?
[14:49:18] <malcom2073> No it's valid, albiet misunderstood. All coil based motors have less torque the further apart the rotor and stator coils get

[14:55:06] <_methods> my understanding of it is that you lose holding torque with increased microstepping
[14:55:22] <lair82> Good Morning Gentleman, We just got my latest build up and running, and I am polishing out the rough edges on all the work I did, and have a question. After looking at these images, http://postimg.org/gallery/2q4vcak52/ what do you think would cause those " chatter " marks in the cut on these bores? I will post this on the forum as well for all the guys that don't use the webchat.
[14:55:25] <pcw_home> Not true
[14:56:08] <pcw_home> thats the misunderstanding people take away from that page
[14:56:53] <Aero-Tec2> is there a way to set a new axis zero in mid Gcode?
[14:57:11] <pcw_home> Tom_itx: probably should ship today
[14:57:11] <Aero-Tec2> some M or G code that can be used
[14:57:32] <Aero-Tec2> one can read values in mid code
[14:57:42] <Aero-Tec2> but can they be set as well?
[14:57:51] <pcw_home> (I have to remember to put some PI5C16211s in)
[14:58:11] <Tom_itx> that would be much appreciated
[14:58:24] <Tom_itx> all 3 are bad
[14:58:32] <lair82> I am not a machinist really, so I am not sure if it is something on my programming end or a mechanical problem, or even a gcode problem.
[14:58:34] <Tom_itx> only 1 pin is bad on one though
[14:58:52] <_methods> lair82: it could be all 3
[14:58:58] <_methods> but how was that circle made?
[14:59:02] <_methods> with a bunch of lines?
[14:59:11] <lair82> With a G03
[14:59:19] <_methods> hmm
[14:59:32] <lair82> 3 IPM feed rate at 1200 rpm spindle speed
[15:00:03] <_methods> on what machine?
[15:00:12] <CaptHindsight> I'm confused as to what people confuse in that paper
[15:00:30] <lair82> Ihave been playing with the G64 P- Q- code, messing with the New Trajectory planner.
[15:00:52] <lair82> It is a Cincinnati Milacron 10VC-1000 VMC
[15:01:15] <CaptHindsight> do they confuse Full Step Holding Torque with Incremental Torque per Microstep?
[15:01:21] <CaptHindsight> or?
[15:01:21] <_methods> ahhh it probably has somethign to do with the trajectory
[15:01:22] <Computer_barf> does acceleration and velocity affect stalling or just acceleration?
[15:01:28] <lair82> 15HP spindle 40" X, 20" Y, and 20" Z travel machine
[15:01:42] <_methods> yeah your machine should be fine for that
[15:01:54] <_methods> and that is waterjetted out?
[15:02:12] <lair82> The bore was flame cut,
[15:02:17] <_methods> ahh
[15:02:29] <_methods> well that heat affected zone could cause some problems
[15:02:46] <_methods> but that looks like a problem with the lookahead/trajectory planner
[15:02:52] <lair82> We are using a 1/2" carbide ALTIN coated endmill
[15:03:12] <CaptHindsight> http://users.ece.utexas.edu/~valvano/Datasheets/StepperMicrostep.pdf
[15:03:15] <malcom2073> Computer_barf: They confuse incremental torque with torque. They assume that since at 1/16th microstepping, your holding torque per microstep would be 9.8%, then you must derate the torque of the motor to 9.8%.
[15:03:29] <lair82> We started with the TP off, then I turned it on, with no real change in the finish.
[15:03:33] <pcw_home> They think u-stepping changes the torque characteristics of the drive/motor, it does not.
[15:03:49] <Computer_barf> malcom2073: sorry i wasn't saying that in context to the wider (incomprehensible to me) conversation
[15:04:35] <SpeedEvil> pcw_home: It can - it can change resonant effects
[15:04:49] <SpeedEvil> pcw_home: which can change the torque before missing steps

[15:07:56] <Computer_barf> ahh
[15:08:27] <pcw_home> Sure higher ustep ratios likely result in more usable dynamic torque
[15:08:28] <pcw_home> but that was not what I was talking about Mayny people read that page and think

[15:08:57] <malcom2073> Right, 9.8% is a lot less than 100% :P
[15:09:05] <malcom2073> Which like you said, is wrong
[15:10:08] <pcw_home> Computer_barf you need to set the stepgen maxvel so you have say 20% headroom
[15:11:13] <Computer_barf> oh i was going to set those 20percent higher once I got the other ones about right. i guess that was a bad idea
[15:11:50] <Computer_barf> ive just been moving velocity and accelleration around alot and got tired of adjusting the 20 percent each time
[15:12:15] <pcw_home> (well if the stepgen gets behind at full speed it can never catch up without some headroom)
[15:13:21] <pcw_home> I wonder if the twopass HAL option would allow variables and some calcs for those numbers
[15:14:00] <Computer_barf> humm maxval went back to too big
[15:15:31] <pcw_home> actually those values should be relatively static (only the scale changes if you are changing the ustep ratio)
[15:16:03] <Aero-Tec2> G10 L20 P1 A0
[15:16:49] <Aero-Tec2> should this not set A axis to 0 at the location it is now?
[15:16:53] <_methods> yes
[15:16:58] <_methods> g54
[15:17:05] <_methods> for g54
[15:17:32] <Computer_barf> put the max velocity to 70 and calculated the stepgen max and now it's not stalling
[15:17:49] <Aero-Tec2> so why when I ran it it did not seem to do it
[15:18:18] <Aero-Tec2> I am running in sim mode
[15:18:37] <_methods> i have no idea how sim mode displays A axis movements
[15:18:48] <Aero-Tec2> and it looks like A axis moves as the value did not jump
[15:18:52] <_methods> i've never tried a 4th axis move in axis
[15:19:12] <pcw_home> not sure if 70 mm/s is fast or slow for your machine/drives
[15:19:23] <Aero-Tec2> will have to run the code for real and see what happens

[15:21:44] <_methods> you're inputting this g10 in the middle of your program?
[15:22:17] <Aero-Tec2> yes
[15:22:27] <pcw_home> you can also trade off accel for velocity
[15:23:24] <pcw_home> That is you can use more accel if you limit the velocity since step motors have much more torque available for accel at lower speeds

[15:31:46] <pcw_home> headroom can also be limited by steplength and stepspace settings
[15:32:20] <pcw_home> (ahh so its warning you of the same issue)
[15:33:39] <pcw_home> so if you already are using minimum steplength and stepspace settings and need more velocity, you will have to lower your ustep ratio
[15:37:37] <Aero-Tec2> _methods, my bad
[15:37:46] <Aero-Tec2> looks like it does do a jump
[15:38:14] <Aero-Tec2> but it looks like it does not really set A0
[15:38:20] <Aero-Tec2> still checking it out
[15:38:45] <Aero-Tec2> but I have larger A movement when it should not
[15:39:16] <Aero-Tec2> and large A axis movement when it should not
[15:39:32] <Aero-Tec2> still making sure it is not me messing up

[15:45:08] <Aero-Tec2> looks like there maybe a small problem

[15:46:06] <Aero-Tec2> and then do a A0 at the start of program

[15:47:08] <Aero-Tec2> I put a G10 L20 P1 A0

[17:22:46] <taiden> i'm having trouble with Autodesk Fusion EMC post
[17:22:51] <taiden> http://pastebin.com/26QV65bR
[17:23:19] <taiden> I came back when this was at the 800th line and trajectory planner is move - stop - move - stop - move - stop
[17:23:35] <taiden> i have this problem a lot with Fusion EMC post processor
[17:23:52] <taiden> any idea on why this might be happening?
[17:24:03] <taiden> My mastercam post file made buttery smooth toolpaths

[17:26:45] <skunkworks> taiden, what version of linuxcnc?
[17:28:01] <taiden> 2.6.4
[17:28:42] <skunkworks> have you tried tweeking G64?
[17:29:03] <skunkworks> G64Px.xxxQx.xxx
[17:29:22] <skunkworks> does it actually stop or just slow way down?
[17:30:43] <JT-Shop> anyone know of a print to pdf for windoze?
[17:31:00] <_methods> pdf-xchange?
[17:31:12] <_methods> or you want to make a pdf?
[17:31:12] <taiden> it's really jittery
[17:31:23] <skunkworks> pdfcreator
[17:31:33] <taiden> for example on a 3 inch radius arc made up of segments
[17:31:50] <_methods> lair82 was having the same problem today with his arcs
[17:31:56] <taiden> it jitters all the way through each segment and shows velocity of 30 ipm instead of 300 ipm
[17:32:23] <skunkworks> try G64 with a P of what max divation you can tollerate
[17:32:48] <taiden> i have tried G64 in the past, it helps but not as much as you'd expect
[17:33:07] <taiden> what's bizarre to me is these same parts cut with my mastercam post (in the past) were extremely fast with none of this hesitation
[17:33:16] <taiden> and no G64 required
[17:33:20] <JT-Shop> I just want to print to pdf
[17:33:25] <skunkworks> where they arcs?
[17:33:32] <skunkworks> instead of short line segments?
[17:33:33] <_methods> print what?
[17:33:52] <skunkworks> pdfcreator is a virtual printer that creates a pdf
[17:33:54] <taiden> well, even when they are actual arcs with Fusion EMC post it still stops between endpoints
[17:34:01] <taiden> and they were segments
[17:34:04] <taiden> on Mastercam
[17:34:15] <taiden> i cant make any sense of it
[17:34:53] <_methods> is this a full diameter or an arc?
[17:34:58] <JT-Shop> yea G64 with no P is the default
[17:35:12] <skunkworks> you could be running into the 1 segment lookahead limitation of the current release version of linuxcnc. 2.7 (next release) has a N-lookahead planner that does much much better.
[17:35:22] <JT-Shop> G64 - without P means to keep the best speed possible, no matter how far away from the programmed point you end up.
[17:36:00] <taiden> if G64 with no P is default and it means to keep the best speed possible
[17:36:11] <taiden> then changing to G64 pxxx should slow i down yeah?
[17:36:44] <JT-Shop> http://linuxcnc.org/docs/html/common/User_Concepts.html#_programming_the_planner
[17:36:59] <JT-Shop> look at the graphic at the end of that section
[17:37:05] <skunkworks> it isn't that simple.. If you do a Px.xxx you do get Q by default the same amount. Q combines line segments that are within that tolerence..
[17:37:29] <skunkworks> (making short segments longer - keeping the speed up)
[17:37:31] <JT-Shop> g64 px "could" slow it down if it needed to to stay within the P tolerance
[17:38:11] <taiden> what im saying is that specifying a tolerance over the default g64 cannot possibly improve speed performance
[17:38:19] <taiden> that's what im understanding anyway :)
[17:38:39] <skunkworks> it does because it also combines line segments that Just G64 doesn't
[17:38:48] <skunkworks> or - it could.
[17:39:07] <skunkworks> test it.
[17:39:08] <taiden> okay
[17:39:26] <taiden> man this is frustrating
[17:39:26] <skunkworks> if performance still isn't good enough - then try 2.7. We need testers :)
[17:39:40] <taiden> any time i try to do 3d surfacing my feedrate drops to 10 ipm
[17:39:56] <skunkworks> what is your acceleration?
[17:39:59] <_methods> yeah
[17:40:03] -!- Swapper_ has quit [Ping timeout: 256 seconds]
[17:40:08] <_methods> accel will have an effect on all that
[17:41:30] <taiden> machine is 900 ipm max and 20in/sec^2
[17:42:37] <JT-Shop> most machines I convert the acceleration is 10-20 times the max velocity
[17:43:13] <taiden> Okay, I'll kick that up then
[17:43:31] <taiden> so 15 in/sec and 150 in/sec^2?
[17:43:33] <JT-Shop> 900IPM is pretty fast...
[17:43:39] amnesic_away is now known as amnesic
[17:43:41] <JT-Shop> yea
[17:43:54] <JT-Shop> can it do 900IPM?
[17:44:08] <taiden> no, this isn't right
[17:44:14] <taiden> yes, it can do 900 ipm
[17:44:18] <lair82> I am running the latest version of master, and am still messing with this, I turned off the new TP, set just G64, and it looks a little better now, but still not 100% yet.

[17:44:44] <skunkworks> turned off the new tp?
[17:44:52] <_methods> lair82: how did it break up the arc?
[17:44:58] <_methods> into quadrants, halves?
[17:45:11] <lair82> I checked backlash, both x and y are 0.000, no lash either axis.
[17:45:13] <_methods> or did your cam do it as one
[17:45:21] <skunkworks> lair82, what is the issue?
[17:45:31] <_methods> he's getting choppy arc
[17:45:33] <taiden> it handles itself really well at normal cutting speeds around 240 ipm, my only issue is this tp dropping feedrates to 10 ipm on low curvature surfaces
[17:45:56] <lair82> http://postimg.org/gallery/2q4vcak52/ this is what my finish looks like
[17:46:24] <lair82> It is one G03 command for the full circle
[17:46:43] <skunkworks> wait - what machine is this?
[17:46:46] <lair82> We are only running at 3-6 IPM
[17:46:49] <_methods> try doing quadrants or hoaves to see if that helps

[17:47:09] <_methods> just as a rule it out type thing
[17:47:11] <taiden> i hate to ask this question on here, but how is Mach3 TP?
[17:47:14] <skunkworks> lair82, I almost garantee that isn't the tp..
[17:47:20] <taiden> i've never used Mach3, only used Linuxcnc
[17:47:31] <lair82> A cincinnati Milacron 10VC machining center,
[17:48:04] <skunkworks> how are you moving the axis?
[17:48:11] <lair82> This is the one that I had all the troubles on a month or so back getting my 7i80 setup, then my NIC wasn't compatible.
[17:48:34] <lair82> I don't follow ?
[17:48:35] <skunkworks> drool: 7i80
[17:48:44] <skunkworks> servos? amps?
[17:49:13] <lair82> Siemens dc servo's with a siemens 3 axis drive
[17:49:31] <lair82> not sure of the size, but they 1984 vintage
[17:49:34] <skunkworks> analog closed loop using mesa?
[17:49:41] <skunkworks> ok
[17:49:48] <lair82> Yep, resolver feedback thru 7i49
[17:50:05] <skunkworks> have you plotted the following error? during a cut like this?
[17:50:08] <lair82> 400 IPM Max rapid
[17:50:51] <skunkworks> and what is your ferror and such set to?
[17:51:34] <lair82> I am running a following error of only 10-20% of the command, 3 IPM feedrate, was at 0.0002-0.0005 F-error
[17:51:58] <skunkworks> My thoughts are a) resolvers not setup correctly (not linear through a rotation), B) servo tuning is off c) mechanical issue.
[17:52:24] <skunkworks> then I would guess a or c....
[17:53:40] <lair82> I watched the axis.0 motor.pos.cmd and the axis.0.motor.pos.fdbk on halscope, and both plots were following each other almost too perfectly, if I move one over the other, they almost look like the same line
[17:54:07] <lair82> zoomed in to 200m
[17:54:07] <skunkworks> that is good..
[17:55:08] <skunkworks> how are you getting the resolvers back into linuxcnc? pico converter or mesa?
[17:55:30] <lair82> I have started lowering my max accel to see if that helped, and my P value to get rid of some of the stiffness, not really much of a change, F-error got bigger though
[17:55:42] <lair82> Thru a 7i49
[17:56:21] <skunkworks> ok. Have you talked to peter about the resolver setup? I think he has ways of testing to make sure the card is setup correctly.
[17:56:54] -!- robinsz has quit [Ping timeout: 245 seconds]
[17:57:38] <lair82> We went back and forth with those when I was doing the wiring and initial setup, We should be setup correctly, in regards to Transformation ratio, voltages, frequency
[18:00:13] <lair82> Speaking of the new TP, I cant really find any docs on it, I can see you questioned "I turned off the new TP". In my INI I have the "ARC_BLEND_ENABLE=" set to 0, and I tried 1 to turn it on and off, but does that not apply anymore?
[18:01:02] <skunkworks> by default (no ini settings) the new tp is on.
[18:01:39] <lair82> Does that line still disable it?
[18:01:45] <skunkworks> yes
[18:02:15] <skunkworks> http://www.linuxcnc.org/docs/2.7/html/config/ini_config.html#sub:TRAJ-section
[18:03:44] <skunkworks> Can you look at the ouptup of the pid? (going to the pwm) and see if it has a cyclic change every rev?
[18:04:05] <taiden> bumped up accel and used g64 p0.01
[18:04:32] <taiden> the linear speed is now very good so I call it a win, but it is still jittery and i wish i knew why!
[18:04:44] <taiden> thanks all for the help :)
[18:05:47] <lair82> skunkworks, Will do heading out there now, just look at axis.0.pid.out on the scope right/
[18:05:59] <skunkworks> right
[18:06:13] <lair82> Ok, give me 5 mins
[18:07:56] <JT-Shop> chrome solved it, you can print to pdf a web page

[18:48:40] <robinsz> 5 tenths maybe
[18:48:54] <robinsz> 2 tenths if you get it decent
[18:49:33] <robinsz> I'd aim for 2 tenths of a thou
[18:49:38] <skunkworks> ^ agreed.
[18:49:49] <skunkworks> but wait is the input scale of the machine?
[18:51:21] <lair82_> resolver scale?
[18:51:46] <skunkworks> how many counts per inch?
[18:51:52] <robinsz> ^^ that
[18:53:17] <lair82_> RESOLVER_SCALE = .199996
[18:53:27] <robinsz> sigh
[18:53:44] <lair82_> Thats all I have to work with
[18:53:59] <skunkworks> do you have a input_scale set in the ini?
[18:54:44] <robinsz> we really should have a button on the desktop "post my ini to pastebin"
[18:55:20] <lair82_> No, you mean something like ENCODER_SCALE right? To set the Pulse per Rev, no this is all I have
[18:55:36] <lair82_> Doing that now,,,

[18:57:15] <skunkworks> well I guess I don't know how resolvers really work in linuxcnc as far as scale..
[18:58:25] <lair82_> http://pastebin.com/JEc4msgK
[18:59:36] <robinsz> id *guess* it scales to 1000ppr
[19:00:19] <robinsz> so he's potentially only got 5000 ppi
[19:00:40] <lair82_> With that value of .199996, 1 inch of travel on an indicator, gives 1 inch of travel on the DRO. my ballscrews are 8MM pitch, resolvers are a 1:1 drive off the screw
[19:01:19] <skunkworks> (float, read/write) scale
[19:01:19] <skunkworks> The position scale, in machine units per resolver electrical revolution.

[19:01:33] <robinsz> 8mm pitch ...
[19:01:50] <robinsz> so 1 turn of the resolver moves the machien 8mm
[19:01:57] <lair82_> yep
[19:02:16] <tjtr33> aventtini, I've used EXEs to translate sinus to ttl. not for Linuxcnc, but for Aerotech CNCs
[19:02:24] <robinsz> im lost as to where the .19999996 comes from then
[19:03:09] <tjtr33> aventtini, not much to it, plug sinus into one end and get ttl out other ( internal jumpers for dividing the sinus aka 'multiplier' )
[19:03:35] <lair82_> My bad, .200 pitch, 1 Rev is .200 give or take on an indicator
[19:03:49] <lair82_> All the other machines in the shop are 8MM
[19:03:54] <skunkworks> I would think it would be .31496 then..
[19:04:11] <robinsz> yep .2 makes sense
[19:04:33] <lair82_> My bad, long week ighting this thing, thank god its almost beer thirty
[19:04:44] <lair82_> "fighting"
[19:04:54] <robinsz> analoge devices make some neat chips that do resolver-to-encoder conversion
[19:05:06] <tjtr33> so does IC-Haus
[19:05:48] <skunkworks> well - the encoder has a simulated 1677216 counts per rev. that should be more than enough resolution to tune down to .0001 atleast..
[19:05:56] <robinsz> right
[19:05:59] <skunkworks> 16777216
[19:06:08] <robinsz> god number
[19:06:12] <robinsz> *good
[19:06:13] <skunkworks> *resolver
[19:06:30] <lair82_> Gurley Precision makes a drop in R11 frame encoder, for about 500 bones a piece,
[19:06:42] <robinsz> gulp
[19:07:05] <skunkworks> The resover is doing exactly what you are telling it to do.. In my opinion - it just needs to be tuned better.
[19:07:12] <robinsz> yep
[19:07:22] <robinsz> which tuning method you use?
[19:07:27] <robinsz> ziegler nicholls?
[19:07:31] <lair82_> Yep, thats why we stay with the resolvers, if I have to replace one, it's 250.00 delivered.
[19:07:32] <skunkworks> trial and error
[19:07:39] <skunkworks> :)
[19:07:49] <tjtr33> 1nanometer? 0.2/16777216 = .000000001 or is that pico ( to dang small to worry about anyway )
[19:07:58] <lair82_> You guessed it, Trial and error,
[19:08:16] <lair82_> When the graph looks good, RUN IT!!!
[19:08:18] <lair82_> LOL
[19:08:19] <skunkworks> I tried ziegler nicholls a long time ago. It didn't work for me. It was made for hydraulic/temp pid loops.
[19:08:49] <skunkworks> lair82: are these velocity mode amps? I assume?
[19:08:53] <robinsz> I use the "turn up P until all hell breaks loose, add some I to calm it down, add some D to make it snappy again without all hell breaking loose"
[19:09:11] <lair82_> yep Velocity
[19:09:27] <lair82_> apparently I need a whole lot more P
[19:09:29] <skunkworks> have you looked at jthornton's tuning instructions?
[19:09:34] <robinsz> nope
[19:09:38] <tjtr33> brazilonth
[19:09:42] <lair82_> I do use his tutorial
[19:09:49] <robinsz> does it involve grpahs?
[19:10:21] <skunkworks> http://gnipsel.com/linuxcnc/tuning/servo.html
[19:10:49] <lair82_> But I kind of stopped when I got below the 1 thou per 1IPM mark,
[19:11:00] <lair82_> sadly apparently
[19:12:28] <lair82_> No point in even getting it setup today, 18 more mins, and it's time for a cold one.
[19:13:05] <lair82_> i will hit it hard monday, get it clamped down as tight as possible,
[19:13:49] <robinsz> i read that tutorial last week and discounted it
[19:13:58] <robinsz> no I or D terms?
[19:14:31] <lair82_> has there been any work on the ATPID component, or is still a POS?
[19:14:49] <robinsz> no clue
[19:15:08] <lair82_> That would make life a whole lot easier ;)
[19:15:49] <robinsz> I solved my "machine only jogs a short distance then stops" problem
[19:16:24] <Computer_barf> does anyone know where i can find the Gpptool directory. I have a postprocessor that im supposed to move to that folder but i didn't see it two directories deep

[19:30:23] <aventtini> no that board that its in the image is the liniar scales bord
[19:30:51] <aventtini> its sin to ttl aleady but i need to get the signal out of them

[21:09:37] <Computer_barf> challenged
[21:09:52] <Computer_barf> you are going to have to do it now.
[21:10:08] <furrywolf> if only it only needed 50 holes...
[21:10:18] <malcom2073> CNC drill!
[21:10:20] <SpeedEvil> furrywolf: M16
[21:10:37] <SpeedEvil> furrywolf: spotwelding?
[21:10:53] <furrywolf> the piano hinges have holes on 2" centers, on both sides, for an average of a hole an inch... I'll probably do the same spacing for the non-hinged sides so it matches...
[21:10:54] <Computer_barf> i imagine its bigger than the workspace
[21:11:22] <furrywolf> it's 20" square and 5" deep, so how many inches of corners is that? :)
[21:12:40] <Computer_barf> im half tempted to build a cnc router table so that I can make my enclosure with it

[21:13:08] <malcom2073> Do it!
[21:13:14] <furrywolf> build a cnc router table to build the parts for your cnc router table? :P
[21:13:30] <Computer_barf> no for my g0704
[21:13:49] <Computer_barf> but yeah then i probably would have to use the router table to make the enclosure for the router table
[21:15:26] <SpeedEvil> furrywolf: 160 holes on the large faces, and I guess another 160 on the touching faces, and 40 on the sides? 360? I'd turn right around and walk away.
[21:18:51] <furrywolf> eh, it's not that many.
[21:19:11] <furrywolf> something wrong with the math there, I hope. :P
[21:21:49] <SpeedEvil> Oh - I read 'a hole an inch'
[21:21:52] <furrywolf> 20 inches square is 80 inches. holes are every two inches, on both sides, for 80 holes. I'll be drilling the angle and the plate at once, not separately. the short sides are 5", probably 2 holes (depending on how I decide to position them), times two, times four, 16 holes. the front cover has a piano hinge on one side, for another 20 holes, then the other sides don't have holes in the cover, only mounting angle that stops it from shut
[21:21:53] <furrywolf> then a few for the latches.
[21:21:58] <SpeedEvil> but you were counting both sides
[21:22:06] <SpeedEvil> half that
[21:22:18] <furrywolf> still 150ish...
[21:23:03] <furrywolf> too many. :(
[21:23:32] <furrywolf> I could use every 4 inches, and either skip rows for the piano hinge, or do the hinges more than the rest of the box.
[21:24:08] <furrywolf> but, the most likely option is I'll just drill way, way too many holes.
[21:24:21] <furrywolf> I kinda like the every 4" idea... it doesn't need to be THAT strong...
[21:24:51] <SpeedEvil> Or if you can drill front and back at the same time, it really speeds it up
[21:25:37] <furrywolf> except there's a lot of asymetrical bits. the back side has two piano hinges, then lid has no holes on 3 sides,...
[21:26:25] <SpeedEvil> ah
[21:26:48] <furrywolf> window a/c units probably don't work at a 45 degree angle, right?

[21:29:32] <XXCoder> also, if you get it out of level for a while it needs a hour or 2 to settle down before turn it on
[21:29:33] <furrywolf> I have an air pop rivet gun.... but that still involves drilling all the holes first. :P
[21:29:57] <XXCoder> depends on size of course, ac probably heck shorter than ref

[21:30:32] <Computer_barf> im sure there isn't any comparison to what you need to do in terms of drilling holes

[21:36:47] <SpeedEvil> furrywolf: Spot welding would be ideal for this
[21:36:51] <SpeedEvil> with the right electrodes
[21:39:02] <furrywolf> spot welding aluminum seems hard
[21:40:31] <furrywolf> I think today I'm going to make my honda eu stator tester... six nightlight bulbs. :)
[21:40:53] <furrywolf> also doubles for testing any other supply of 240v-ish 3-phase.
[21:42:07] <furrywolf> I'd prefer 3 240v bulbs, but 240v bulbs don't exist here.

[21:49:51] <furrywolf> bleh. the only plastic I can find is some old plexi, and I know from experience I'm not drilling six large holes in that without it exploding.

[22:09:29] <MrSunshine> damn, some greace in the Z axis linear berings removed almost all visible shatter on the sides of my cut pieces .. when i was going to grease it i remember my last thought 1.5 years ago when i assembled it was "lets not grease it good now .. i will remove them later and grease them" .. well .. i didnt ..
[22:09:34] <MrSunshine> they were almost bone dry :P
[22:10:03] <furrywolf> lol
[22:10:52] <MrSunshine> tho, they were used stuff when i put them there .. now they are even more used and rattles around on the axles .. i guess $100 to replace axles and berings wouldnt be bad for the machine :P
[22:13:12] <XXCoder> MrSunshine: yeah forgetting is annoying

[22:16:43] <MrSunshine> and when you get the machine running you get so excited that you realy forget =)
[22:17:09] <MrSunshine> that i even dismantled it and painted it was quite impressive imo :P
[22:17:41] <malcom2073> Ok I soaked my ways in another coating of evaporust, see how it does when it's actually at the proper temperature heh
[22:17:46] <XXCoder> :)
[22:18:31] <malcom2073> It did pretty good last time, even though it was only 50F, and it's supposed to be above 60-70
[22:19:12] <furrywolf> evaporust won't work in coating form. it needs to liquid, and able to flow. best suggest I've heard for things too large to submerge is to apply paper towels and soak, or to spray with a pond pump.
[22:19:31] <malcom2073> Yep, I have soaked paper towels along with saran wrap around the whole thing
[22:19:32] <furrywolf> suggestions
[22:19:48] <furrywolf> I haven't tried the pond pump solution, but it seems like a good one...
[22:19:54] <malcom2073> gonna go re-wet it every half hour for probably 2-3 hours
[22:20:57] <malcom2073> Last time, I soaked it and left it overnight
[22:21:10] <malcom2073> Had to scrub to get the remanents of the paper towels off, but it cleared off most of it

[22:35:54] <malcom2073> If he comes out with a 7i77e before I actually find the money to buy, I'll probably get that

[22:36:58] <malcom2073> not that I know of? searching again now
[22:37:24] <malcom2073> Doesn't look like it
[22:37:34] <furrywolf> hrmm, doesn't look like it. I must have imagined it. lol
[22:37:53] <XXCoder> malcom2073: not bad
[22:38:03] <XXCoder> good percent rust removed
[22:38:22] <furrywolf> it's listed on the mesa bitfiles page...
[22:38:46] <malcom2073> But not on their product pages :/
[22:39:46] <malcom2073> It's gonna be a couple months, so he's got time to get one out :-P
[22:40:07] <furrywolf> it's listed on the ethernet driver, which is probably where I saw it, as I read it looking up the 7i76e.

[22:48:01] <malcom2073> Wait you trading machines or drive systems? :-P
[22:48:15] <furrywolf> lol
[22:48:19] <furrywolf> what's your machine? :P
[22:49:45] <malcom2073> Clausing FV-1 : http://mikesshop.net/millmove/image030.jpg
[22:50:58] <furrywolf> sure, I'll definitely trade. :P
[22:51:15] <malcom2073> Why, what do YOU have? :-P
[22:51:19] <malcom2073> Shipping would be hell
[22:51:27] <furrywolf> a chinese lathe/mill combo machine. :P
[22:51:31] <malcom2073> haha
[22:52:11] <furrywolf> I should take a current photo... http://fw.bushytails.net/shoptask02.jpg is it before cleaning and CNCing.
[22:52:36] <malcom2073> Oh that's a nice little machine
[22:53:12] <furrywolf> it's the largest of the chinese tabletop mill/lathe combos... got about a 10x11" useful machining area in mill mode.
[22:53:35] <furrywolf> see gallon can for size reference
[22:53:45] <malcom2073> Yeah it's pretty good sized for a tabletop
[22:53:47] <furrywolf> of course, at 650lbs, it probably weighs less than just the head on yours. :)
[22:54:08] <malcom2073> haha
[22:54:14] <malcom2073> I think the head on mine is only like 400
[22:54:24] <malcom2073> I hope, cause I gotta lift it up at some point
[22:54:32] <furrywolf> lol
[22:55:01] <furrywolf> mine is movable by one person if you separate the major components and don't mind grunting a bit.
[22:55:08] <malcom2073> That's good
[22:55:40] <furrywolf> obviously, at 650lbs, I'm not deadlifting it... but I can lift the head, saddle, etc separately, then grunt and move the base around.
[22:56:13] <malcom2073> Haha yeah
[22:56:21] <malcom2073> Get a small engine hoist and you're set to go anywhere with it
[22:56:29] <alex4nder> hah
[22:56:33] <XXCoder> grunt for power!
[22:56:42] <furrywolf> the head is, dunno, 200lbs... I can carry it around, but I wouldn't want to long distances.
[22:56:53] <malcom2073> Gotta go respray my paper towels, brb
[22:57:21] <furrywolf> make sure to squish them around or something too... you want to expose the metal to fresh evaporust.
[22:59:01] <malcom2073> Yep, used a glove to push the air bubbles beneath the paper towels out
[23:00:10] <XXCoder> need to smuh em around too, so rust is loosened and new rust exposed to chemical
[23:00:43] <malcom2073> Yeah, next time I go down I'll replace the paper towels and wipe it down
[23:01:14] -!- asdfasd has quit [Ping timeout: 246 seconds]
[23:02:37] <furrywolf> XXCoder: it doesn't work by loosening rust. the rust is dissolved into the chemical. that's why you have to make sure you get fresh chemical to the area.
[23:02:50] <XXCoder> ahh
[23:03:54] <furrywolf> once the chemical has dissolved a certain amount of rust, it becomes useless...
[23:06:07] -!- [cube] has quit [Ping timeout: 250 seconds]
[23:08:06] <XXCoder> makes sense
[23:08:23] <XXCoder> guess it uses itself up. some chemical causes reaction but dont involve itself in it
[23:10:10] <furrywolf> their advertising claims it's chelation, a type of molecule that bonds to metals well...
