[02:06:49] <Jymmm> oh man..somebody wants to buy my 4 d cell led maglite (snif snif)
[03:13:08] <DJ9DJ> moin
[03:17:26] <alex_joni> moin
[03:57:36] <sebastian> hello
[03:58:19] <sebastian> i've a question
[03:58:33] <sebastian> can i set homing paramaters with HAL at runtime?
[04:00:27] <sebastian> such as HOME_OFFSET
[04:07:42] <micges> no
[04:08:48] <sebastian> is there another way to set those variables at runtime?
[04:09:09] <sebastian> MDI, Shellscript, whatever,...
[04:26:12] <awallin> if they are read from the INI once when linuxcnc starts then it might be tricky..
[05:33:36] <jthornton> sebastian, what is your desired results?
[06:17:27] <sebastian> jthornton, i want to change HOME_OFFSET via HAL
[06:20:14] <jthornton> I read that but why?
[06:20:39] <sebastian> i need to do homing twice, but with different home offsets
[06:21:35] <jthornton> why can't you use a different coordinate system?
[06:23:22] <sebastian> i made something like a gantrymachine
[06:24:10] <jthornton> what is the second homing move for?
[06:25:12] <sebastian> i want the second axis to have another offset than the first
[06:25:23] <sebastian> but both use the same joint in HAL
[06:25:39] <jthornton> you have two spindles on on axis
[06:25:50] <sebastian> two motors
[06:25:52] <sebastian> yes
[06:25:55] <jthornton> on one axis
[06:26:05] <jthornton> just change coordinate system for second one
[06:27:33] <jthornton> homing is only to set the physical limits of your machine and provide a reference point for the machine origin
[06:28:06] <jthornton> if you home again to a different location the soft limits will not work anymore
[06:28:34] <sebastian> i know that
[06:29:00] <sebastian> it's hard to describe for me, it's a quite complicated workaround
[06:29:31] <jthornton> to use G54 for one spindle and G55 for the second?
[06:29:45] <sebastian> i just need to change the HOME_OFFSET at runtime
[06:29:52] <jthornton> you can't do that
[06:29:56] <sebastian> ok thanks
[06:30:43] <jthornton> have you looked at G92 as a possible solution to your strange problem?
[06:31:04] <sebastian> no, i'll have a look
[06:39:00] <sebastian> no, it does not solve my problem
[06:39:05] <sebastian> thanks anyway
[06:39:23] <jthornton> ok I'm out of ideas as I don't really know what the problem is
[06:39:59] <sebastian> ok i'll try to describe
[06:40:18] <sebastian> i have two physical steppers
[06:40:42] <sebastian> in hal i only use one joint for both
[06:40:59] <sebastian> so most of the time they run synchron
[06:42:34] <jthornton> both are on the same axis but can move independent of each other?
[06:42:41] <sebastian> yes
[06:43:11] <jthornton> and?
[06:43:23] <sebastian> i made component that calculates the difference between the position of the first and the second motor
[06:44:18] <sebastian> so i can disable one of the motors, to move the other independently
[06:44:51] <sebastian> so i want to do homing twice
[06:45:03] <sebastian> first time the motors run synchrone
[06:45:34] <sebastian> then i disable one of them and rehome
[06:46:03] <sebastian> the second time i wanna have another offset
[06:46:47] <sebastian> crazy stuff, i know...
[06:48:19] <jthornton> why can't you have the second motor as a second linear axis?
[06:48:52] <sebastian> i've tried this as well
[06:49:01] <jthornton> do you have a photo of this beast?
[06:49:08] <jthornton> what was the result of that?
[06:49:12] <sebastian> got a lot of joint following errors
[06:49:28] <jthornton> on a stepper system?
[06:50:01] <sebastian> yes, it gets command feedback from the stepgen
[06:50:18] <sebastian> no sorry, i do not have a foto
[06:50:35] <jthornton> is the joint following errors caused by your component?
[06:50:42] <sebastian> yes
[06:50:53] <jthornton> have you looked at the thc component?
[06:51:11] <sebastian> i think i'll refactor the idea with the 2 linear axis
[06:51:21] <sebastian> what is this?
[06:51:54] <sebastian> tetra hydro cannabinol???
[06:52:10] <jthornton> it's my torch height control and I hyjack the Z axis and move it at will to keep the tip voltage constant while lying to the step gen about the actual position
[06:53:03] <jthornton> 2 linear axis and moving via g code would/should be the easy way
[06:54:14] <jthornton> I am curious what does this machine do?
[06:54:27] <sebastian> it's just a gantrymachine
[06:55:36] <jthornton> doesn't sound like "just a gantrymachine" :) what do you make on it?
[06:55:50] <sebastian> the second motor just moves a few millimeters for homing
[06:57:16] <sebastian> sure, i have one physical X axis, that has 2 motors, on the right and left side
[06:58:06] <jthornton> ok, so the two motors are the ones that move the gantry, I thought you had two spindles
[06:58:22] <sebastian> no, two steppers
[06:58:41] <jthornton> one on each side of the gantry right?
[06:59:01] <sebastian> yes
[06:59:15] <jthornton> so the upshot is your trying to square the gantry?
[06:59:36] <sebastian> yes
[07:00:29] <jthornton> the simple way for a stepper gantry is to physically push the gantry against a hard stop and home without a switch so that position is 0
[07:01:45] <sebastian> but that sounds a bit brutal
[07:02:03] <sebastian> my solution works pretty well
[07:02:13] <jthornton> so do you have independent home switch inputs for each side of the gantry
[07:02:21] <sebastian> yes
[07:02:43] <jthornton> so, first one wins or is it always one side first?
[07:03:12] <jthornton> are you using gantrykins?
[07:03:20] <sebastian> always one side, for first time, one homeswitch is disabled
[07:03:23] <sebastian> hell no!
[07:03:53] <sebastian> gantrykins do not work
[07:04:04] <jthornton> just asking
[07:04:09] <sebastian> only in automode
[07:05:02] <jthornton> so you home one side, block the step input to that drive then home the other side?
[07:05:21] <sebastian> yes
[07:07:10] <jthornton> just thinking out loud early in the morning but that should just work... unless your home point is not the same
[07:07:40] <jthornton> can you physically adjust the home switch on each side to get them in sync?
[07:07:53] <sebastian> yes
[07:07:58] <sebastian> that works well
[07:08:11] <sebastian> but it would be better to do it logically
[07:08:49] <sebastian> that's the only problem i have left
[07:08:50] <jthornton> how would you tell logically if your not square?
[07:09:23] <jthornton> and I understand your fixation on the home offset now...
[07:09:25] <sebastian> not sure, what you mean?
[07:09:41] <sebastian> ok, good
[07:10:17] <jthornton> how do you calculate the offset needed to get the gantry square?
[07:10:48] <sebastian> i can show you the component i wrote
[07:10:54] <jthornton> it seems only possible to physically adjust the home switches to get a square gantry
[07:10:57] <jthornton> ok
[07:11:04] <sebastian> one moment
[07:19:03] <sebastian> http://pastebin.com/hjyWWLsr
[07:20:37] <sebastian> this allows me to move one motor independently
[07:21:22] <Jymmm> jthornton: Hey
[07:21:31] <jthornton> Jymmm, hay
[07:21:52] <sebastian> otherwise the other motor would always move to the position of the other one, after enabling it
[07:22:50] <sebastian> sorry about my english...
[07:23:24] <jthornton> np, it is better than my <insert any language here>
[07:23:34] <Jymmm> jthornton: In the quotes I've been getting to have ss sheet cut, all are around $11/ea in thousands qty, but when jump to 100's of thousands not much of a drop. When you need that higher qty, how are things usually done?
[07:23:55] <Jymmm> er 10's of thousands, not 100's
[07:24:15] <jthornton> things?
[07:24:27] <sebastian> ????
[07:24:38] <Jymmm> reactangle and a dics with holes.
[07:24:42] <jthornton> at Jymmm
[07:24:47] <Jymmm> 6x12" and 3"
[07:25:05] <jthornton> punch press
[07:25:20] <jthornton> but you have to buy a $10k die
[07:25:45] <Jymmm> anything inbetween laser and punch press?
[07:25:55] <jthornton> not really
[07:26:27] <Jymmm> at $10K die, I'd rahter buy the damn laser.
[07:26:46] <jthornton> sebastian, would it not be easier to write a component to just block the output of step gen to the first motor?
[07:27:32] <jthornton> does your component move the second motor?
[07:27:42] <jthornton> I can't really tell what it does...
[07:29:12] <Jymmm> jthornton: Is $86 a good price on 26ga (0.0188") 4x10 SS 304.2B
[07:29:33] <jthornton> never purchased any...
[07:29:46] <Jymmm> oh
[07:30:09] <Jymmm> jthornton: how you make production line stuff w/o ss sheet?
[07:30:36] <jthornton> and the market changes so fast if I had purchased some 6 months ago the knowledge would not be valid any more
[07:30:55] <Jymmm> heh
[07:31:22] <jthornton> I've only made one machine for the food industry and the parts were supplied by a machine shop at the time
[07:31:35] <Jymmm> ah
[07:31:51] <Jymmm> wait, what shop?
[07:32:30] <Jymmm> in house to the factory shop?
[07:33:20] <jthornton> the machine shop I did the design work for
[07:33:29] <Jymmm> oh, gotcha
[07:34:40] <sebastian> jthornton, yes would be easier, but does not work with mesa, because stepgen there is on the firmware and i have no influence on it with HAL
[07:35:25] <jthornton> and the plot thickens...
[07:36:20] <jthornton> so you have two stepgens both getting position input from the same source?
[07:36:31] <sebastian> yes
[07:36:48] <sebastian> but one gets it by the component above
[07:38:25] <jthornton> have you looked at the thc component yet?
[07:38:31] <sebastian> but the input of my component is the same pos
[07:38:43] <sebastian> have you got a link?
[07:39:59] <jthornton> http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=blob;f=src/hal/components/thc.comp;h=01c0128cf3b3e2d14eb0f2b4b1e62ae52b67dec4;hb=refs/heads/v2.5_branch
[07:40:28] <jthornton> key line for you is z_fb_out = z_pos_in; // keep axis motor position fb from being confused
[07:44:51] <sebastian> ok, i'll try that
[07:45:14] <Jymmm> jthornton: This is slick... http://www.tubeservice.com/TubeServiceVideo.html
[07:45:24] <jthornton> I think that is the only way it might work
[07:47:20] <awallin> set it up, build a webstore, and sit back and watch the cash-flow? completely automated warehouse and production...
[07:47:34] <awallin> well maybe it isn't that easy to get it working lights-out
[07:47:46] <skunkworks> TGIF!
[07:47:55] <jthornton> yea
[07:48:34] <alex_joni> 4pm friday even ;)
[07:49:23] <alex_joni> awallin: sure it is, employ blind people for loading/unloading, and you probably get some state funding too
[07:49:40] <Jymmm> this is so messed up…. there are a gang of ppl going around in richmond telling ppl they are with chevron and they can file a claim to get free medical after the fire… all we need is your drivers license, social secuirty and your bank account so we can transfer funds to you… they already got at least 30 ppl… Ya gotta love it.... Nothing like a slimeball taking advantage of a shitty situation. Remember Katrina???
[08:12:51] <skunkworks> I still have people at work here that freak out every time they get a phishing email.. Is this real?
[08:13:21] <skunkworks> I didn't send 1492.75 through bill pay!
[08:13:39] <syyl> "a talking deer wants to know my credit cards pin number? sounds fair!"
[08:14:04] <Jymmm> Too bad you know they fscked something up in it's design... http://www.frys.com/product/7169522?site=sa:adpages%20page:P7_FRI%20date:081012
[08:14:15] <Jymmm> skunkworks: I dont get how gullible ppl are.
[08:14:28] <Jymmm> a lil common sense goes a LOOOOOOOOOOOOONG way.
[08:15:59] <Jymmm> Sadly, they even had ppl from the BAR come down to make sure the lawyers werent screwing ppl over too.
[08:16:36] <Jymmm> they were handing out flyers to victims as well.
[08:55:00] <pcw_home> "jthornton, yes would be easier, but does not work with mesa, because stepgen there is on the firmware and i have no influence on it with HAL"
[08:55:02] <pcw_home> This is not true, you have full control of the hardware stepgen in HAL (though you may need to put it in velocity mode and use an external PID loop to get access to everything)

[09:55:11] <ssi> any HNC owners awake?
[09:55:59] <cradek> just ask your real question
[09:56:18] <ssi> do you recall whether the 90v supply that feeds the drives is AC or DC?
[09:57:06] <cradek> the drives surely take DC
[09:57:16] <cradek> I don't recall whether it's 90v or not
[09:57:29] <cradek> the drives have a huge filter cap on each one
[09:57:29] <ssi> I would assume so, I just can't recall seeing any rectifier of any significant size in the drive supply
[09:57:35] <ssi> yeah that's the output cap though
[09:57:48] <cradek> don't you have docs for the drives?
[09:57:49] <ssi> the servos connect directly to the big cap and ground
[09:57:49] <skunkworks> output cap?
[09:57:56] <ssi> yeah I do, but not here
[09:58:04] <ssi> I've been meaning to sheetscan the drive manual forever
[09:58:18] <cradek> well I can tell you for sure that there's not AC on that big electrolytic cap
[09:58:23] <ssi> I'm starting to believe peter's theory about brownouts causing the faults when the compressor comes on
[09:58:29] <ssi> yeah I know, they're DC servos for sure
[09:58:39] <ssi> just not sure if the drive itself rectifies or if it's dc before that
[09:58:45] <cradek> yes mine sure does that (ferrors if it's rapiding when the air compressor starts)
[09:58:47] <ssi> I'm going to go through and see what it'll cost to replace all the caps
[09:59:01] <ssi> oh really?
[09:59:03] <ssi> it's pretty irritating
[09:59:04] <cradek> really
[09:59:06] <cradek> yep
[09:59:13] <ssi> you using the hiak drives?
[09:59:19] <cradek> yes the original drives
[09:59:43] <ssi> good to know, thanks
[10:00:08] <cradek> I don't have the greatest power there, and a large 1ph air compressor
[10:00:22] <ssi> my power's pretty decent, but my compressor is 5hp
[10:00:34] <ssi> and I noticed last night that the lights dim noticably when the compressor starts
[10:00:45] <cradek> 5hp on single phase 240v?
[10:00:48] <ssi> yep
[10:00:51] <cradek> yeah ouch
[10:01:11] <ssi> I have 200A service, and mostly it's not a problem
[10:01:22] <ssi> I never had this problem before, but I haven't been running much this summer
[10:01:30] <cradek> put a vfd with soft start on your air compressor!
[10:01:30] <ssi> thinking that with all the ACs going, I'm straining my service limits
[10:01:34] <ssi> yeah thought about that
[10:01:44] <ssi> but that'd require replacing the motor I guess
[10:01:51] <ssi> I dunno if you can vfd a single phase motor
[10:01:55] <cradek> yeah unfortunately
[10:02:06] <ssi> and I replaced that motor recently
[10:02:11] <ssi> and it wasn't cheap
[10:02:14] <ssi> I bought a US made leeson for it
[10:02:18] <cradek> my portable compressor has a clutch so the motor can start unloaded
[10:02:38] <cradek> it probably couldn't start at all otherwise (120v)
[10:02:41] <ssi> haha
[10:02:55] <cradek> still has trouble when on an extension cord
[10:03:09] <cradek> it runs the motor all the time and only cycles the clutch
[10:03:24] <cradek> guess it needs a crank to start it up, haha
[10:03:26] <ssi> my compressor is a big 18cfm IR single stage, and it's right by my panel wired with under 6 feet of 8 gauge
[10:04:02] <cradek> my big one is dual stage, forget the cfm, it's a big tank, 6' tall
[10:04:08] <cradek> also 5hp on single phase
[10:04:31] <ssi> I also want to try to get a 5hp VFD for the HNC
[10:04:36] <ssi> I have that motor on a 3hp VFD right now,
[10:04:41] <ssi> and I get decel faults way too often
[10:04:43] <cradek> it's only a 2hp motor
[10:04:49] <ssi> I have the decel ramp set really long
[10:04:50] <cradek> add a braking resistor
[10:04:52] <ssi> I don't know why it's a problem
[10:05:03] <cradek> a bigger vfd won't help, add a braking resistor
[10:05:06] <ssi> well the drive is the type that doesn't have an internal IGBT, so you need a spendy braking module
[10:05:11] <cradek> oh heck
[10:05:13] <ssi> yeah :/
[10:05:27] <ssi> 3hp vfds that run on single phase are somewhat hard to come by
[10:05:33] <cradek> with all those pulleys and crap, there's a lot of mass on that spindle
[10:05:35] <ssi> I think 5hp is near impossible to get on single phase
[10:05:46] <ssi> I might oughta just get the original electromechanical brake fixed and reinstalled
[10:05:49] <cradek> yes, pretty sure 3 is as big as you can get
[10:06:18] <ssi> you're running the original spindle motor with all the goodies under there?
[10:06:20] <cradek> do you have a cheapie 2hp vfd you could try? with braking it might work better
[10:06:31] <ssi> nah... I have a 1hp and a couple of 1/4hp ones :P
[10:06:34] <cradek> yes there's a 2x4 holding the varispeed thing in the right place
[10:06:40] <ssi> yeah that's exactly how mine's set up haha
[10:06:41] <cradek> haven't touched it otherwise
[10:06:49] <cradek> I do use the gear change
[10:06:50] <ssi> but I would really like to get the varispeed working as a high/low gear
[10:07:00] <cradek> don't you have the high/low clutches going?
[10:07:05] <ssi> yes
[10:07:19] <ssi> but in low clutch, the bottom end of the range is too fast and torqueless for good rigid tapping
[10:07:31] <ssi> I can do it, but not as slow as I'd like
[10:07:34] <cradek> ah
[10:07:37] <ssi> and it sometimes balks at starting that slow
[10:07:55] <ssi> I have a job I've been running (just finished) that rigid taps M10, and sometimes the motor just won't start on that part of the program
[10:07:59] <ssi> it'll sit there and twitch back and forth
[10:08:13] <ssi> I probably could program it to start faster and slow down
[10:08:23] <cradek> wonder if you've got a wonky vfd
[10:08:23] <ssi> but I'd really love to have the ability to switch the varispeed into low
[10:08:30] <ssi> maybe
[10:08:36] <ssi> it certainly isn't high end
[10:09:11] <ssi> was thinking about rigging up an arduino as a standalone device that knows how to run the stepper up and down to the travel limits
[10:09:16] <ssi> and then rig a mesa pin to control it
[10:10:07] <cradek> there are limit switches on that mess
[10:10:17] <cradek> it'd be very easy to do in hal
[10:10:48] <ssi> yeah
[10:10:53] <cradek> the hard part is making sure the spindle is turning while you change it
[10:11:14] <ssi> ohh good point
[10:11:15] <cradek> varispeed sucks that way - if you stop in high speed and then mount something heavy or floppy, you're screwed
[10:11:40] <cradek> you might want a vfd with jog input
[10:11:43] <ssi> well I don't think that'd be too too much of a problem... can always use low clutch to get it started
[10:12:02] <ssi> I don't really anticipate mounting anything particularly heavy on that machine... it's really not made for big parts
[10:12:03] <cradek> that's true. you could use low clutch whenever you want to change the varispeed.
[10:12:16] <ssi> in fact I am quoting another job that needs 4" roundbar stock
[10:12:23] <ssi> and it's a hassle cause now i need to find a 4" step chuck/closer
[10:12:33] <cradek> I'd do it all in hal
[10:12:40] <cradek> eek, 4" is very big for that machine
[10:13:15] <cradek> brb
[10:15:14] <ssi> it's 4" dia, but only 1.25" long
[10:15:18] <ssi> if I can workhold it, it'll be fine
[10:29:27] <cradek> have a faceplate?
[10:29:57] <cradek> would be easy to make a fixture if so.
[10:47:18] <ssi> I like the collets better for that kind of work because it's fast and repeatable
[10:47:36] <ssi> I just ran a 100pc job with a 2" step collet, making parts that were out of 2" roundbar and 1.95" finished
[10:47:54] <ssi> and the collets worked out amazingly well. I had to machine one side and then flip over and second op the other side, and the concentricity was great, and they were fast and easy to do
[10:48:00] <ssi> only downside is having to buy the step collets
[10:55:12] <jthornton> I have one job that is 3.25" in diameter and 0.625" thick and I use the bore it out yourself 5c collet for it
[11:21:48] <ssi> yea that's what I'm talking about
[11:21:53] <ssi> do you use a closer ring with it?
[11:21:57] <ssi> or is it one of the ones that doesn't use a ring
[11:22:38] <jthornton> it
[11:22:42] <jthornton> 's the cheap one
[11:22:51] <ssi> gotcha
[11:22:58] <ssi> here's the parts I made in a 2" step closer:
[11:22:58] <ssi> http://p.twimg.com/Az8wNBACUAI4rOA.jpg:large
[11:23:14] <jthornton> nice
[11:23:24] <ssi> they're faced and od turned with the radius, drilled, chamfered, and tapped halfway through
[11:23:40] <ssi> parts are about 3/8" overlength to start with, and held in the collet in a 2" .250 deep section
[11:23:54] <ssi> and then flipped over and held by the new turned 1.95" diameter in a .500" deep section of the collet
[11:24:07] <ssi> faced, chamfered, tapped, and then the radius is cut
[11:24:14] <ssi> and if they're not dead concentric, the radius looks terrible
[11:24:30] <ssi> I have to be very careful that there aren't any chips in the bottom of the collet before I seat the part
[11:24:31] <jthornton> this is the lightened one http://smokeandstuff.com/index.php/products/lightweight-puck-saver
[11:24:37] <jthornton> yea
[11:24:57] <ssi> tapping pushes chips down to the bottom of the bore and I have to blow it out every third part or so
[11:25:05] <ssi> yea those look good
[11:25:18] <jthornton> this is the standard one http://smokeandstuff.com/index.php/products/standard-puck-saver
[11:25:37] <jthornton> just faced on each side with a radius on the edge
[11:25:41] <ssi> right
[11:26:11] <ssi> the new part this guy wants me to make is only like 2.75" od, but it's got a 3.58" flange, so I have to make it out of 4" stock
[11:26:20] <jthornton> I also made these for fun http://smokeandstuff.com/index.php/products/custom-engraved-puck-saver
[11:26:23] <ssi> I'm telling him that he needs to redesign it to be 3.45" flange, because 3.5" stock is WAY cheaper
[11:26:30] <ssi> like 30% cheaper
[11:26:35] <jthornton> and a lot less chips
[11:26:37] <ssi> yep
[11:26:49] <ssi> he didn't like the price I gave him
[11:26:58] <ssi> haha those fancy ones look awesome
[11:27:03] <jthornton> thanks
[11:27:54] <ssi> how do you get your stock for those?
[11:27:55] <jthornton> I made a jig from some soft jaws the second op has a pin that lines up with one of the holes to get the position right
[11:27:58] <ssi> cut to length, or do you cut it yourself
[11:28:05] <jthornton> I cut it myself
[11:28:31] <ssi> the thing that I noticed is that if my bandsaw isn't set up dead square when I'm cutting stock, it becomes about impossible for me to turn those parts concentric
[11:28:45] <ssi> it wouldn't be so big a deal if i wasn't trying to turn to so close the raw diameter
[11:28:49] <jthornton> scott gets it from a place that buys the material as scrap from big companys that have the 4f thing
[11:29:01] <ssi> I buy from metal supermarket mostly, and they charge the same price regardless of how you have it cut
[11:29:05] <ssi> so I have them cut them to length for me
[11:29:08] <ssi> and their saw cuts dead square
[11:29:25] <jthornton> yea my first bandsaw was like that and the one I use now cuts dead square
[11:29:28] <ssi> I think they hate me a little bit when I come in and order 100 pieces 2.75" long
[11:29:36] <ssi> but hey, that's how they set up their pricing model :)
[11:30:03] <jthornton> if someone ordered 100 of anything from me I'd be happy
[11:30:39] <ssi> haha yeah
[11:31:01] <ssi> I have a reasonably nice bandsaw now, and I'm sure I can get it running square enough to be happy with, but I haven't yet
[11:31:16] <ssi> it's a grizzly 7x12 saw... HUGE improvement over the old shitbox HF 4x6 that I had
[11:31:51] <jdh> hey, my shitbox HF is great (for the price)
[11:32:03] <ssi> yeah, for the price nothing beats having a bandsaw
[11:32:13] <jthornton> this photo shows my new bandsaw http://gnipsel.com/shop/inside/inside-06.xhtml
[11:32:14] <ssi> but my $800 grizzly saw is WORLDS better than the $250 HF saw
[11:32:30] <ssi> that is nice jt
[11:32:32] <ssi> nicer than mine I think
[11:32:43] <jthornton> when you get a Wilton you will hate your grizz
[11:32:50] <ssi> I'm sure
[11:33:02] <ssi> grizz surely isn't top of the line
[11:33:13] <jthornton> my other one is a 3/4" blade and the cool blocks move all over the place
[11:33:14] <ssi> did you buy that saw new?
[11:33:18] <jthornton> yes
[11:33:48] <ssi> what did it cost, if you don't mind my asking?
[11:33:57] <jthornton> do you wash the coolant off of your aluminum parts?
[11:34:05] <ssi> yeah
[11:34:08] <ssi> I'm running neat oil
[11:34:10] <ssi> brb
[11:34:20] <jthornton> ah ok
[11:34:38] <jthornton> I don't recall the price but I can get the model number if you want it
[11:35:54] <jthornton> be back later
[11:43:24] <jdh> ssi: $179 HF
[12:13:48] <IchGuckLive> Hi all
[12:20:50] <Loetmichel> re @ home
[12:21:21] <IchGuckLive> B)
[12:25:02] <IchGuckLive> hi bence connected via greek hub where are you joining from
[12:50:20] <skunkworks> huh - i have a 5 bay older norco esata raid box that became very flakey. it pretty much stopped showing up on linux. It ended up being the powersupply. 12v was 11.09 and 5v was 3.7. rigged in a normal computer supply and it came right up. Now building a 8tb raid 5 array :)
[12:57:06] <Jymmm> been there done that. Working on 24TB RAID5 via ZFS
[12:58:08] <Jymmm> skunkworks: Hint: use an intel nic/chipset
[12:59:09] <Jymmm> skunkworks: Realtek have bugs in the linux driver code
[13:01:13] <skunkworks> I have been using these for nas http://www.newegg.com/Product/Product.aspx?Item=N82E16813182233
[13:01:22] <skunkworks> I like them so far.
[13:01:47] <skunkworks> (or similar - not exatly that model)
[13:02:15] <skunkworks> bonding the 2 GB cards.
[13:02:32] <skunkworks> gb
[13:04:47] <Jymmm> looking...
[13:05:33] <Jymmm> internal USB, nice.
[13:05:51] <Jymmm> internal USB slot (not just header), nice.
[13:06:09] <skunkworks> right
[13:06:27] <Jymmm> it has intel chipset =)
[13:06:47] <skunkworks> only a bit more than twice a cheap intel atom
[13:06:48] <Jymmm> skunkworks: check this out http://www.newegg.com/Product/Product.aspx?Item=N82E16813153212
[13:07:27] <Jymmm> skunkworks: it also has 6GPIO pins =)
[13:07:36] <skunkworks> cool
[13:08:08] <Jymmm> and paraport, LVDS (LCD), sound, intel nics
[13:08:28] <skunkworks> I liked the super micro because it has a pci-e slot instead of the pci
[13:08:32] <Jymmm> and RS 232/422 serial
[13:08:45] <Jymmm> what are you adding?
[13:09:27] <Jymmm> oh and USB3
[13:09:36] <skunkworks> esata card
[13:10:29] <Jymmm> it has PCI and Mini PCIe
[13:11:18] <skunkworks> the supermicro only has usb2
[13:14:06] <Jymmm> 1 Serial header (RS232/RS422/RS485)
[13:14:17] <Jymmm> skunkworks: http://www.jetwaycomputer.com/NF99.html
[13:14:41] <Jymmm> - Longlife Components for 24/7 use in industrial application
[13:15:12] <Jymmm> skunkworks: I heard it can acceot up to 8GB ram too
[13:15:50] <Jymmm> skunkworks: Your onboard raid is "windows only" it says, I'm not sure if the jetway is too or not
[13:16:22] <Jymmm> skunkworks: I'm not trying to charge your mind, just sharing what I've found
[13:16:26] <Jymmm> change
[13:17:48] <skunkworks> me too :)
[13:18:51] <skunkworks> I don't use the onboard raid - and I only use 'inexensive' esata cards and use soft raid. It still seems magnatudes faster than the network thoughtput
[13:19:02] <skunkworks> *inexpensive
[13:20:25] <Jymmm> skunkworks: the reason I was pushing the jeyway is if you got one, then repurposed it later, you can STILL use it for emc, media player, etc since it has a LOT of I/O on it. It also has 6 GPIO pins as well
[13:20:55] <Jymmm> plus it has LVDS it you wanted to embed it in/on an LCD panel.
[13:21:08] <Jymmm> aka touch screen
[13:22:24] <skunkworks> sure
[13:23:31] <Jymmm> skunkworks: with the 6 GPIO pins, for small project you can avoid those highly overpriced, suck support options that mesa has. Right PCW?
[13:24:07] <skunkworks> (I would rather go mesa...)
[13:24:10] <skunkworks> :)
[13:24:30] <Jymmm> If anyone cares, great lil knife with fire steel built in. Just orderd 2 more http://www.rei.com/product/847921/tool-logic-sl3-fire-folding-knife-2012-overstock
[13:24:50] <Jymmm> great price too
[13:25:59] <Jymmm> has removeable pocket clip too
[13:27:26] <Jymmm> I've still trying to find a REAL (carbon) knife though.
[13:28:49] <Jymmm> The SL4 adds a LED light, but I heard the fire steel likes to break in them, as they are thinner.
[14:15:15] <Jymmm> djdelorie: Heh, just find the "installer" for pkz204g.exe - it's only 198KB!!!
[14:15:19] <Jymmm> found
[15:54:52] * jthornton just successfully issued his first linuxcnc python interpreter command :)
[15:55:20] <Jymmm> quit?
[15:56:18] <Jymmm> jthornton: DUDE! You (and your friends) made the news!!! http://news.yahoo.com/blogs/sideshow/family-four-bears-breaks-cabin-drink-100-beers-181034427.html
[16:01:30] <DJ9DJ> gn8

[16:02:09] <Tom_itx> err gr8
[16:03:51] <Tom_itx> good stuff jthornton
[16:51:15] <Dave911> >>> just successfully issued his first linuxcnc python interpreter command ------ oh no... Python .. Its like crack.. once you start you can't stop.. ;-)
[16:51:59] <Jymmm> No, that's Lay's Potato Chips.
[16:52:50] <archivist> there is a cure...never start coding python
[16:59:49] <Jymmm> http://m.wired.com/gadgetlab/2012/08/apple-amazon-mat-honan-hacking/
[17:01:08] <archivist> Jymmm, you were looking for a deep throat punch, I restored one this last couple of weeks http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_08_09_Barber_Colman/IMG_1291.JPG
[17:02:11] <Jymmm> archivist: cool =)
[17:03:11] <archivist> no idea who made it though
[17:04:01] <ink_> haha
[17:04:08] <ink_> <3 python
[17:07:29] <ssi> it'd be nice to be able to cast iron and make stuff like that whenever you want :D
[17:08:27] <ink_> mmm
[17:09:25] * ink_ kinda wants to build a proper kiln
[17:09:40] <ssi> yea me too... as projects go, it's pretty far down my priority list though
[17:10:52] <ink_> yeah
[17:11:03] <ink_> that's the kind of thing that would be a lot easier to do if I actually owned land
[17:11:06] <ink_> heh
[17:11:41] <archivist> space and money and time
[17:14:55] <Jymmm> http://www.youtube.com/watch?v=zMabEyrtPRg&feature=player_embedded
[17:18:26] <archivist> anyway punch has done its first job, punching holes in gasket material for the hobbing machine's restoration
[17:24:01] <jy76> test 1-2 ping
[17:24:46] <archivist> phail
[17:25:42] <jy76> i thought it was supposed to be pong:) !!! ive been tring to get this to work for months
[19:13:57] <linux-cnc-bob> hi
[19:14:29] <linux-cnc-bob> i am making a circular pocket 1" deep, but my cutter effective length (end mill) is only 3/4".. is it ok to use it still for delrin?
[19:17:18] <alex4nder> the shank isn't 'back cut'?
[19:17:38] <alex4nder> "undersized"
[19:27:32] <linux-cnc-bob> nope
[19:37:30] <alex4nder> linux-cnc-bob: well I hope you like friction then
[19:37:51] <alex4nder> or overcut the top 1/4"
[19:47:31] <linux-cnc-bob> ok thx
[20:08:33] <Tom_itx> ReadError g10?
[20:08:43] <ReadError> yea
[20:08:45] <ReadError> fr4
[20:08:54] <Tom_itx> oh
[20:08:56] <Tom_itx> no
[20:09:00] <ReadError> phenolic resin
[20:09:01] <Tom_itx> you mean production?
[20:09:04] <ReadError> idk it has alot of names
[20:09:13] <Tom_itx> what color?
[20:09:18] <ReadError> its basically just fiberglass sheet ;)
[20:09:22] <ReadError> black or so
[20:09:26] <ReadError> quit follow me toner !
[20:09:46] <Tom_itx> you want a fab house that does color?
[20:10:01] <ReadError> well i just need a couple 12x24" sheets
[20:10:07] <ReadError> ive seen a site a bit back, that had them
[20:10:12] <ReadError> but cant for the life of me find it
[20:10:39] <Tom_itx> the fr4 is copper color until you etch and mask it
[20:10:49] <ReadError> nah
[20:10:55] <ReadError> thats copper clad FR4
[20:11:00] <ReadError> but FR4 alone is just the fiberglass
[20:11:16] <Tom_itx> ok so you just want the fiberglass with no copper on it
[20:11:21] <ReadError> yessir
[20:11:27] <ReadError> i currently get it from amazon
[20:11:29] <ReadError> but its ugly yellow
[20:12:02] <Tom_itx> can't help you with that
[20:14:13] <ReadError> i do need some 60degree carving endmills though
[21:40:53] <Jymmm> ReadError: thickness?
[22:01:37] <ReadError> Jymmm: around 0.090 ish
[22:27:29] <jy76> whats everyone building?
