[00:00:27] <tjb1> so a 20" extrusion - 8" carriage leaves about 12" before I add all the supports and thrust bearings
[00:00:54] <tjb1> and this really bothers me - http://www.cnczone.com/forums/attachment.php?attachmentid=162586&d=1341087087
[00:01:22] <r00t4rd3d> why
[00:02:09] <r00t4rd3d> the cable drag is really not needed on the Z
[00:02:18] <r00t4rd3d> should have just ran the wire with the Y
[00:02:45] <tjb1> That isn't mine
[00:02:57] <tjb1> I read a lot on cnczone ;)
[00:03:01] <r00t4rd3d> i didnt figure seeing how your parts were just sent
[00:03:20] <tjb1> It bothers me that 1 they are using e-chain on the z axis which has about 8" travel
[00:03:38] <tjb1> and 2 they have about 2 ft of it when according to mcmaster slightly over half of travel is all that is required
[00:03:49] <tjb1> so 12" would have sufficied
[00:04:34] <r00t4rd3d> i wouldnt have put it on my z at all
[00:04:37] <r00t4rd3d> looks like shit
[00:06:28] <tjb1> I agree
[00:07:28] <tjb1> http://www.cnczone.com/forums/attachment.php?attachmentid=162580&d=1341087068
[00:07:31] <tjb1> that one bothers me too
[00:14:16] <r00t4rd3d> i need to find a way to manage the wires going into my controller
[00:14:25] <r00t4rd3d> thats the only thing i dont like
[00:14:41] <r00t4rd3d> http://i.imgur.com/IMQyO.jpg
[00:15:10] <tjb1> That little box?
[00:15:22] <r00t4rd3d> yeah
[00:15:28] <r00t4rd3d> the black one
[00:15:34] <tjb1> Only 3 wires there
[00:15:41] <r00t4rd3d> 4
[00:15:51] <tjb1> Thats so messy
[00:15:54] <tjb1> You should be ashamed
[00:16:01] <r00t4rd3d> it does irritate me

[00:16:12] <tjb1> Position of the g540

[00:18:47] <r00t4rd3d> when i get some money im gonna get that and put it all on there
[00:18:49] <tjb1> Thats nice
[00:19:07] <tjb1> I can't spend any money until I get something made
[00:19:28] <tjb1> I won't have enough to "finish" it
[00:19:57] <r00t4rd3d> i built my xyz basically twice
[00:21:10] <tjb1> I only have $750 left
[00:21:16] <tjb1> $500 of that is steel for the frame
[00:21:34] <tjb1> Still need a water table, leveling feet and echain

[00:29:00] <Jymmm> tjb1: save $500 =)
[00:29:18] <tjb1> Heh, they already removed all the old rail lines here

[00:45:40] <taiden> the problem with a long z is you need a long mount so you can actually use it, and a tall gantry
[00:45:49] <taiden> which makes things all sorts of bendy

[00:46:28] <taiden> so i'd say make it as small as possible but add extra travel to make up for any tolerances in your designs
[00:46:47] <taiden> and then adjust your limit switches to be safe for your setup so you aren't jamming things into the wrong places (that's what she said)

[03:22:57] <tjb1> I would sue the dump cops
[03:23:00] <tjb1> *dumb
[03:23:15] <tjb1> It that hard to watch where you are shooting
[03:23:31] <Valen> from the armchair no
[03:23:48] <Valen> on a busy street when somebody is trying to kill you i imagine it gets a bit tougher
[03:23:58] <tjb1> The guy was walking away
[03:24:13] <Valen> The veteran patrolmen who opened fire on the suit-clad gunman, Jeffrey Johnson, had only an instant to react when he whirled around and pointed a .45-caliber pistol at them as they approached from behind on a busy sidewalk, police said.
[03:24:16] <tjb1> The guy killed who he wanted and was leaving
[03:24:34] <tjb1> Ok but 16 shots?
[03:24:35] <tjb1> 16...
[03:24:44] <Valen> yeah, thats a bit much
[03:25:01] <tjb1> Worst part is, 16 shots between 2 cops
[03:25:03] <Valen> when your using a crowd as the back stop double tap and wait
[03:25:04] <tjb1> Not like 6 were hsooting

[03:26:08] <Valen> do keep in mind that you could fire off 8 shots in a second or two
[03:26:28] <Valen> and it takes that long for the guy to start falling down
[03:27:49] <Valen> tis funny when paintballing, the first 100 balls get used up in about 4 minutes
[03:27:56] <Tom_itx> aww just toss a grenade his way
[03:28:12] <Valen> the next hundred last 20 minutes, and the 3rd hundred the rest of the day

[05:07:15] <Skullworks> Does not ring a bell - but its been nearly 12hrs since my last cup of coffee.
[05:07:54] <Jymmm> Skullworks: .25 http://en.wikipedia.org/wiki/Ortgies_Semi-Automatic_Pistol
[05:09:36] <Jymmm> Skullworks: It's in need of some TLC, just nobody knows it enough
[05:11:13] <Skullworks> 25acp aka 6.35x16 is a weak round - the 32 is better and the 9mm K (aka 380acp) is even better
[05:12:49] <Jymmm> Skullworks: I have a G17, but it's not very "compact" as I'm in Calif. The .25 I have just won't fire correctly; dimples rounds, but doens't fire.
[05:13:43] <Jymmm> tried different ammo brands too
[05:14:26] <Skullworks> whats wrong with it - I would thing that a complete teardown, wash in hot water with Tide in a ultra sound tank, blow out with compressed air and oil EVERYTHING with Breakfree CLP.
[05:15:41] <Skullworks> yup - need to use a pipe cleaner thruogh the firing pin hole - make sure there is no junk gumming up the movement of the pin.
[05:16:01] <Jymmm> No ultrasound, but do have a nitrogen tank to blow/displace water.
[05:16:21] <Skullworks> but it needs to be fully stripped down when you clean it.
[05:17:01] <Skullworks> CA... I'm a long displaced political refugee from there...
[05:17:23] <Jymmm> heh, you sound like you are in Texas
[05:17:24] <Skullworks> Good times back in the day
[05:17:30] <Skullworks> Colorado
[05:17:35] <Jymmm> ah, ok
[05:18:12] <Skullworks> Left the Domesticated West coast for the midwest free zone.
[05:19:41] <Skullworks> Texas raises great cattle and great Women, but it also tends to raise the temp higher than I prefer too.
[05:19:57] <Jymmm> Heh, and humidity!!!
[05:20:35] <Skullworks> Oh please - not that... I have family in FL and MO
[05:20:49] <Skullworks> Purgatory!
[05:21:08] <Jymmm> I said humidity, not hurricanes =)
[05:21:19] <Jymmm> Skullworks: This is what I have... http://i50.tinypic.com/x6kfpv.jpg
[05:21:46] <Jymmm> no parts list
[05:21:57] <Skullworks> If you take 1 sylable out of MO its pronounced Misry
[05:22:43] <skunkworks__> Skullworks: It g64px.xxx activates the naive cam - that tries to blend multible segments together so that the effective length is longer - so velocity is higher...
[05:22:48] <Jymmm> dont tell that to JT-Shop-3 Skullworks, he lives there =)
[05:23:53] <Skullworks> Lots of fine folk there - just not my style.
[05:24:34] <Jymmm> Skullworks: you like breakfree over copper grease?
[05:25:57] <Skullworks> I was wondering it there was a way to extend the look ahead such that the velocity is not limited to what the machine can stop in one or 2 blocks.
[05:26:54] <Jymmm> I'd suspect so, with inverse in overall speed
[05:26:56] <Skullworks> Copper grease is OK for internal areas where the grease can not escape - I don't like it for exposed areas
[05:27:48] <Jymmm> Skullworks: Ah, I've been using in mostly on the slide for my G17; never heard of breakfree before.
[05:28:21] <Jymmm> s/in/it/
[05:29:13] <Jymmm> Skullworks: would tide bath w/o ultrsound tank do any good?
[05:29:16] <skunkworks__> Skullworks: not at the moment... but if the segments are colinear withing the px.xxxx then they will be combined into a longer segment..
[05:30:05] <Jymmm> oh sorry there Skullworks, I had mistaken you two
[05:30:10] <Jymmm> skunkworks__:
[05:30:16] <Jymmm> that is
[05:30:32] <Skullworks> I would think that even cutting a spline path with segments of maybe .002" could be done at full speed if the breaking acceleration can be applied in a controlled method where the machine continues to follow the programmed path within the G64 P(tol).
[05:30:39] <Jymmm> all you SK's look alike ;)
[05:31:25] <Skullworks> I run a puny Knee mill and he has that Monster K&T
[05:31:41] <Jymmm> heh
[05:32:00] <skunkworks__> runs fast enough for me.. still can destroy things before I can get to the estop..
[05:32:18] * Jymmm lol @ skunkworks__
[05:32:24] <Skullworks> Oh I'm sure.
[05:32:30] <Jymmm> skunkworks__: NEED MORE BRB's!
[05:33:04] <MattyMatt> my plywood mill bends while it scratches things
[05:33:19] <MattyMatt> I don't need no e-stop
[05:33:27] <Jymmm> MattyMatt: you need more duct tape
[05:33:31] <Skullworks> His K&T is one of the greatest EMC2 (at the time) success storys.
[05:34:26] <MattyMatt> I do want more lookahead tho. I noticed it comes to stop at all 4 points of an oval that should be a smooth movement
[05:35:04] <Jymmm> MattyMatt: is that PC HW related or emc ?
[05:35:14] <Skullworks> what G64 P value are you using - AND are you using backlash comp?
[05:35:25] <MattyMatt> no G64 used yet
[05:35:33] <MattyMatt> no backlash comp
[05:36:01] <Skullworks> you use Inch or mm?
[05:36:05] <MattyMatt> mm
[05:36:27] <skunkworks__> try g64
[05:36:44] <Skullworks> try adding a "G64 P.04"
[05:37:03] <MattyMatt> yarr I will, when I'm not working on my last bit of plywood stock :)

[05:43:08] <MattyMatt> I recently discovered that axis jogs way better with the 3d turned off
[05:43:31] <Skullworks> I nick named my truck "Darth RoadKill" Because even when you swerve to avoid them they turn and run back under the truck...
[05:43:33] <skunkworks__> that is odd...
[05:43:33] <MattyMatt> that surprised me, I thought the jogging would be on a higher priority thread
[05:44:06] <theos> :)
[05:44:19] <MattyMatt> but meh, no 3d hardware, so I guess openGL has blocking parts

[05:46:23] <MattyMatt> I finally noticed that it got worse with bigger files, so I suspected the 3d, so switched to DRO tab and pow all fixed
[05:46:43] <MattyMatt> 15┬Ás iirc
[05:47:00] <skunkworks__> the gui gets sluggish as it is not a realtime task
[05:47:03] <Skullworks> Software step/dir to stepper motors?
[05:47:27] <MattyMatt> yarr. yeah I guess the jogging is GUI not real time as such
[05:47:34] <skunkworks__> hook up hardware jog buttions... or a jog wheel... :)
[05:48:14] <MattyMatt> are they treated differently to the keyb? excellent
[05:48:29] <MattyMatt> jog wheel in construction
[05:48:38] <Skullworks> may also look at the typematic keyboard A20 setting in BIOS
[05:48:41] <skunkworks__> you will love it!
[05:49:03] <Skullworks> that can cause overtravels
[05:52:32] <MattyMatt> eeh. I could flip burgers for a day and buy a bleeding jogwheel
[05:53:00] <MattyMatt> except McFlippery has a 6 month waiting list for jobs
[05:54:12] <MattyMatt> I should go pimp my gcode skills at all the local machinists
[05:54:42] <Skullworks> McD's is a crazy statistic - more than 1 in 7 people in the US has worked for McD's at some point.
[05:55:07] <MattyMatt> some point in the calculus sense?
[05:55:43] <MattyMatt> tending towards zero but never actually flipping that burger?
[05:55:56] <Skullworks> at some time during there term as tax payers.
[05:56:24] <Jymmm> MattyMatt: I thought they have a fancy grill that doens't require actual flipping
[05:56:55] <Jymmm> dual sided microwave of sumtin =)
[05:57:00] <MattyMatt> I think they were still flipping last time I was in there
[05:57:03] <Skullworks> true - some people may have been employed, but never actually worked - looks that way at some local franchises.
[05:58:11] <Jymmm> Hey, I worked. As a contract locksmith for them =)
[05:58:25] <Skullworks> the auto flip is the chain conveyor used to flame broil at BK.

[06:00:21] <Jymmm> that is actually impressive
[06:02:09] <Skullworks> bbl - need to go move laundry to the dryer
[06:02:46] <Jymmm> MattyMatt: Donate bodily fluids?
[06:03:10] <MattyMatt> NHS = free both ways
[06:03:22] <MattyMatt> they get my corpse for the med students

[06:04:34] <MattyMatt> they'd take a kidney if I was feeling generous, but they absolutely won't pay
[06:05:05] <MattyMatt> would need 2 pints for a jogwheel :)

[06:09:58] <Jymmm> (if we're sterotyping that is)
[06:10:31] <MattyMatt> grandfather's farm was burned down by mad brother. him and mad one came to England, the other 3 went to Florida

[06:24:07] <Jymmm> second?
[06:24:12] <Jymmm> what's first?
[06:24:27] <MattyMatt> one of the few british sizes that's the same pitch as US
[06:26:38] <toastydeath> Jymmm, another random bolt
[06:27:53] <toastydeath> 1/2 x 13 and 3/4 x 10 are pretty common too
[06:28:09] <MattyMatt> our 1/2 is 12tpi iirc

[07:34:33] <Skullworks> Kinda wished they had gone farther with Torchwood. If anything the "office" looked like fun.
[07:35:33] <MattyMatt> did that get destroyed in the "real" timeline? it did in a couple of alternates
[07:36:46] <MattyMatt> yeah it did I think, they were homeless in the american story
[07:37:14] <Skullworks> not that I recall - it was the last one, and I think the plot might have left it vacant (can always bring something back...)
[07:37:34] <MattyMatt> which they seem not to be in a hurry to make more of. big budgets and british sci-fi don't always work
[07:38:14] <Skullworks> but I may have missed some of the shorts after the end of the second season.
[07:38:48] <Skullworks> sci-fi is always the first to get the axe.
[07:39:16] <MattyMatt> they did a 3 part mini-series then the american one which was 6 or 8 parts
[07:39:33] <Skullworks> missed those
[07:40:11] <MattyMatt> with luck they won't wipe the VT
[07:40:36] <Skullworks> from Jan 6th to july 10th I was working 7 days a week - I took 1 sick day.
[07:41:12] <MattyMatt> although BBC just cleared out of their TV building after 40 years. I bet some stuff went in the bin
[07:42:30] <Skullworks> They fired my Boss and the Engineering assistant and it was just me - trying to keep 8 radio stations on air covering half the state - and I'm supposed to just be a part timer.
[07:42:40] <MattyMatt> and Bush House where the world service was made. all custom equipment

[07:46:43] <MattyMatt> and then 6 managers above them to keep on-message

[11:41:28] <jthornton_> from the manual STEPGEN_MAXACCEL = 21.0 - Acceleration limit for the step generator. This should be 1% to 10% larger than the axis MAX_ACCELERATION. This value improves the tuning of stepgenĺs "position loop". If you have added backlash compensation to an axis then this should be 1.5 to 2 times greater than MAX_ACCELERATION.

[17:08:50] <IchGuckLive> the behabvier on G76 in mill and lathmode is different
[17:09:24] <Connor> I understand. I have a different profile for my mill when I have it turned like this.
[17:09:33] <Connor> It's setup as a lathe.
[17:09:45] <IchGuckLive> ok so lathe
[17:11:45] <Connor> yup.
[17:12:00] <Connor> I have the ID of the part around 17.6mm ATM.

[17:14:32] <IchGuckLive> conner querry

[17:18:36] <IchGuckLive> M20 means mayx 20mm tread is 1mm depth
[17:19:03] <Connor> 1.0 is the pitch.
[17:19:07] <IchGuckLive> 55Degree
[17:19:28] <IchGuckLive> pitch is also the Depth of the Treat on metric
[17:19:58] <syyl> metric thread with 55deg?
[17:20:02] <IchGuckLive> M6 is 1mm yu drill 5
[17:20:16] <Connor> okay, so bore out to 19mm..
[17:20:19] <IchGuckLive> M8 is 1,25 you drill 6.8
[17:20:27] <Connor> then use 1mm for depth..
[17:20:35] <IchGuckLive> M10 is 1.5 you drill (.5
[17:20:39] <Connor> how deep should I run each pass ?
[17:20:40] <IchGuckLive> ....
[17:20:56] <Connor> this is cold roled steel.
[17:20:59] <IchGuckLive> 0.15
[17:21:09] <syyl> depends on the machine and the tool you use
[17:21:39] <Connor> HSS cutter that I'm going to have to grind myself.. CRS, on my G0704 mill running in lathe mode.
[17:22:04] <IchGuckLive> try 0.15
[17:22:09] <syyl> that will work

[17:44:42] <Connor> not sure if you can get that locally or not.
[17:44:51] <Connor> I'll use a sharpie on the pvc..
[17:45:38] <Connor> First things first though is making the threading bit.

[17:47:12] <Connor> I would too.. but.. I have a few blank HSS cutters from LMS that I can grind them down on.
[17:47:41] <Connor> besides, I'm not planning on doing internal threads every day..
[17:47:47] <IchGuckLive> Connor: for practis shape is no factor

[17:50:53] <Jymmm> pipe or sheet?
[17:51:13] <Connor> Boarded out Rod.
[17:52:01] <Jymmm> I'd try MDF first, then go from there
[17:52:19] <syyl> mdf is hard to get as a round bar ;)
[17:52:25] <Jymmm> It likes to hold threads thru the surface really well.
[17:52:40] <Jymmm> syyl: Just a general tapping test medium
[17:52:51] <syyl> he wants to turn the thread
[17:52:59] <syyl> no tap involved

[17:53:37] <Connor> IchGuckLive: Yes, but this is 1.0
[17:53:39] <IchGuckLive> M20x1mm i never found this
[17:54:03] <Jymmm> syyl: How's that?
[17:54:16] <syyl> all that crap in it makes the hss dull
[17:54:19] <syyl> pretty fast
[17:54:27] <syyl> i would not run my expensive taps in mdf
[17:54:54] <Jymmm> crap?
[17:55:15] <Jymmm> there is no grain to mdf, I haven;t seen an isue yet
[17:55:22] <Connor> Jymmm: The glue, the grit, the formaldehyde.
[17:55:32] <syyl> then run your tools in mdf :P
[17:56:00] <Connor> anyway, I have some PVC pipe for testing with.. that'll be easier.. less messy.. I have issues with Allergies and MDF.

[19:14:57] <djdelorie> it would be if I actually put the design files up there :-)
[19:15:07] <djdelorie> now that the firmware is working, I should do that...

[19:27:29] <jthornton> pcw_home, I see that in some sim configs so I was wondering

[19:28:26] <pcw_home> if thats
[19:28:53] <jthornton> I suspect that it is some ini smoke and mirrors to leave the base thread out

[22:50:32] <JT-Shop> in Axis?
[22:51:56] <andypugh> Yes
[22:52:52] <andypugh> He is using 0.1mm end mills, so really wants microns in the DRO.
[22:54:05] <PCW> Thats pretty weensy, how the heck to you spin them?
[22:54:22] <PCW> Dentist drill?
[22:54:36] <Tom_itx> i had trouble holding a #79 drill in mine the other day
[22:55:09] <Tom_itx> even with a pen drill holder it wanted to slip
[22:55:25] <andypugh> I think they have normal-sized shanks
[22:55:36] <PCW> PCB drills do (1/8)
[22:55:54] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/reprap/nozzle5.jpg
[22:56:03] <Tom_itx> this was a straight shank #79
[22:56:17] <Tom_itx> i couldn't find my #80 or i'd have tried it
[22:57:07] <Tom_itx> i think the .1mm is smaller than that but i'm not sure
[22:57:09] <andypugh> PCW: You know that chap with the Omron drives which are acting odd? Same chap.

[22:59:22] <JT-Shop> can he add a pyVCP panel and display the DRO numbers there?
[22:59:52] <andypugh> I guess so, but it seems to me it ought to be possible as a .axisrc entry?
[23:00:05] <PCW> Oh, that guy I suggested he try torque mode to get as much of the drive out of the way as possible
[23:00:07] <PCW> I think he's got some kind of mechanical/drive issues that make his "plant" untunable
[23:00:15] <JT-Shop> yea, just stabbing about in there now looking
[23:00:30] <andypugh> I spent today trying.
[23:00:54] <JT-Shop> I think it might be in axis.tcl
[23:01:01] <JT-Shop> but dang if I can find it now
[23:01:25] <andypugh> The initial peak is 6um, the rest of the f-error is about 2um with 0.3um static error. For most folk that would be considered pretty good.
[23:02:32] <r00t4rd3d> well SOB
[23:02:34] <r00t4rd3d> http://www.thingiverse.com/thing:13757
[23:02:58] <andypugh> You can get it better (less than 2um initial peak) by tuning FF1, but only for one specific feed rate. I think his answer might be mapped-gains.
[23:03:01] <JT-Shop> line 559 in axis.py redraws the dro but nothing in there about digits
[23:03:42] <PCW> Or jerk limited motion
[23:04:04] <andypugh> Mapped-gains is easier.
[23:04:41] <PCW> Yes but S curves are better for everyone
[23:04:57] <andypugh> Also, not unusual, one controller I am calibrating at work has the I-gain determined as the product of 3 8x8 maps.
[23:05:30] <PCW> Can he run his loop any faster?
[23:05:48] <andypugh> He has tried, but his PC isn't great.
[23:06:19] <andypugh> I think I persuaded him to get the machine up and running and making parts, and see how they turn out.
[23:06:23] <PCW> This is where atoms fail but core DUOs work well
[23:07:07] <andypugh> In most cases a lathe tool isn't touching the work at the start of motion, so it is entirely possible that it simply won't matter.
[23:07:35] <PCW> Yeah
[23:08:19] <PCW> And if you can trade of speed for accuracy. lower the accel
[23:08:25] <PCW> trade off

[23:09:18] <andypugh> I think I will be back. Did you see his titanium conrods?
[23:09:58] <PCW> No, I saw the injectors and O rings, those were impressive
[23:11:43] <skunkworks__> pcw: did you try a video card in your atom?
[23:12:17] <PCW> No, let me try it right now!
[23:12:22] <skunkworks__> heh
[23:13:28] <JT-Shop> andypugh: beyond my level of guesspertice
[23:15:06] <andypugh> in and mm have different numbers of digits, so it can't be _that_ difficult?
[23:16:28] <JT-Shop> if you can find it, I'd think it would be trivial

[23:17:25] <JT-Shop> I did get emccalib.tcl to run from the menu in my GUI... too bad I was wanting showhal.tcl but a copy and paste error sent me down the wrong path today
[23:17:50] <PCW> Well that didnt get very far, it wont work with add-on video cards in the PCI slots
[23:18:34] <PCW> (well the BIOS didn't anyway)
[23:18:43] <andypugh> jthornton: I am going to guess line 1724 in axis
[23:19:23] <skunkworks__> oh - I have had that issue with certain motherboards. (pci video cards just don't boot)
[23:19:55] <Tom_itx> JT-Shop how is your software project going?
[23:20:17] <JT-Shop> the GUI thing?
[23:20:35] <Tom_itx> yeah
[23:20:41] <JT-Shop> andypugh: axis.py?
[23:20:51] <JT-Shop> Tom_itx: learning more and more every day
[23:21:03] <andypugh> Yes, though the version in usr/bin is just called axis
[23:21:45] <JT-Shop> yes, I think you have found it
[23:22:00] <JT-Shop> fmt = "%4f"
[23:22:01] <andypugh> ah, no, that's just for the gcode properties dialog box
[23:22:27] <JT-Shop> yea, just reading uphill
[23:22:52] <JT-Shop> Tom_itx: I managed to get emccalib.tcl to run from a menu...
[23:22:56] <PCW> skunkworks: it boots, it just ignores the PCI vide0 and always uses the internal video. maybe theres a BIOs option...
