[00:21:56] <archivist> Crom_, how about truetype tracer with a stencil font http://timeguy.com/cradek/truetype
[01:07:30] <adam3999_> hey guys, i posted a note on the forum with my parport issue hoping to reach a wider audience. any help would be appreciated greatly: http://linuxcnc.org/index.php/english/forum/18-computer/28929-no-input-signals-w-asrock-q1900m-onboard-parport

[02:45:06] <MacGalempsy> Hi Deejay :)
[02:46:36] <archivist> so Deckel machines are often regarded as one of the best, how come in the collection of manuals I got yesterday they are the dirtiest
[02:51:41] <MacGalempsy> dirty as in fecal coliforms or oil
[02:53:52] <MacGalempsy> one would be toilet reading and the other would be requires a lot of work
[02:54:28] <archivist> oily black as in used a hell of a lot
[03:09:54] <archivist> Deckel pr0n http://www.dialog5.com/officialmachinephotos.htm
[03:21:30] <MacGalempsy> well teckle my deckle
[03:23:12] <MacGalempsy> bbiab
[03:28:37] <zeeshan> man this is confusing me
[03:28:56] <zeeshan> im testing out my cnmg inserts
[03:28:58] <zeeshan> vs ccmt
[03:29:06] <zeeshan> tried it on steel, stainless, aluminum
[03:29:17] <archivist> you're confused! what do you think we are
[03:29:37] <zeeshan> aluminum is somewhat dull with the cnmg insert
[03:29:55] <zeeshan> stainless and steel both have a rough finiish
[03:29:56] <archivist> al needs sharp and the right lube
[03:30:18] <zeeshan> you can see tiny pieces of metal embedded in the finished surface
[03:30:22] <archivist> work hardening for stainless and steel
[03:30:26] <zeeshan> when i use ccmt insert using the same cut parameters
[03:30:31] <zeeshan> i get an amazingly shiny surface
[03:30:42] <zeeshan> in all 3 materials
[03:30:48] <archivist> so you learn geometry matters
[03:31:00] <zeeshan> why is the negative rake tooling being a pain
[03:31:08] <zeeshan> i know theres more cutting forces
[03:31:12] <zeeshan> whats flexing?
[03:31:19] <archivist> negative is only for roughing
[03:31:40] <zeeshan> ive seen some videos where peop-le are using cnmg
[03:31:44] <zeeshan> and they get spectacular finishes
[03:31:55] <zeeshan> but they're bigger lathes
[03:31:58] <archivist> dont expect shiny except on perhaps brass with negative
[03:32:28] <zeeshan> i feel like something is loose in the lathe :/
[03:32:32] <archivist> depth of cut is probably your error
[03:32:44] <zeeshan> no
[03:32:47] <zeeshan> im, running 500 sfm
[03:32:51] <zeeshan> 30 thou doc
[03:32:52] <archivist> negative needs to be under the skin
[03:32:55] <zeeshan> and .006 ipr
[03:32:59] <zeeshan> thats the spec on the insert
[03:33:01] <zeeshan> for both
[03:33:23] <zeeshan> even if i reduce to .005 doc
[03:33:24] <zeeshan> its no good
[03:33:56] <archivist> flexible toy lathes need not apply for hard work too
[03:34:08] <zeeshan> its a 1000 lb lathe
[03:34:11] <zeeshan> it should take it! :P
[03:34:28] <zeeshan> im gonna try eliminating the compound slide
[03:34:30] <zeeshan> maybe its moving
[03:34:53] <zeeshan> i mean if the lathe is flexing
[03:34:59] <zeeshan> then i should be able to put a dial indicator on the base
[03:35:01] <zeeshan> and see it flex?
[03:35:50] <archivist> I was shocked at the amount of flex when first told how to see it
[03:36:11] <zeeshan> how do you see it
[03:38:06] <archivist> put a bar in the spindle, a dti down the bed somewhere lean on headstock or bed or wherever
[03:39:26] <zeeshan> whats the point of the bar
[03:39:39] <zeeshan> oh plunger of dti is on the bar
[03:39:45] <zeeshan> how long of a bar
[03:40:27] <archivist> long enough to show spring
[03:40:57] <zeeshan> i wonder if bolting a 1" plate
[03:41:01] <zeeshan> at the base of the lathe
[03:41:03] <zeeshan> is worth it
[03:41:04] <zeeshan> to reinforce it
[03:41:12] <archivist> I had about 4 thou spring
[03:41:28] <archivist> is the lathe on a wooden bench
[03:41:32] <zeeshan> no
[03:41:41] <zeeshan> its sitting on 2 cabinets
[03:42:34] <archivist> separate?
[03:42:36] <zeeshan> yes
[03:42:51] <archivist> ouch, bolted?
[03:42:57] <zeeshan> yes
[03:44:31] <zeeshan> to be honest with you
[03:44:32] <archivist> little/no added stiffness from the mounting then, a bit like my first attempt, I was getting a taper, went to a machine rebuilding place, got educated
[03:44:33] <zeeshan> i remember a while back
[03:44:36] <zeeshan> seeing my compound flex
[03:46:54] <zeeshan> will work on it one thing at a time :)
[03:47:14] <zeeshan> i shoulda bought that monarch lathe! :P
[03:47:29] <archivist> yes you should
[03:47:37] <zeeshan> the only thing that sucks about it
[03:47:41] <zeeshan> is its max speed is like 1000 rpm
[03:48:11] <archivist> fast enough for a mans metal
[03:48:14] <zeeshan> haha
[03:48:18] <zeeshan> what i need is a mikron cnc lathe!
[03:48:32] <zeeshan> after seeing how good a real cnc mill is
[03:48:39] <zeeshan> i dont even wanna bother around with this shitty 12x36t
[03:49:50] <archivist> you are learning why good is also big
[03:50:38] <zeeshan> i was doing 20 ipm cuts
[03:50:40] <zeeshan> in steel on the mill
[03:50:44] <zeeshan> was fun
[03:52:03] <archivist> I think the importance of machine flex is lost on many people
[03:52:40] <zeeshan> yup
[03:52:52] <zeeshan> im gonna have to make this lathe work for now
[03:53:01] <zeeshan> i got the x-axis backlash down to 0.0003"
[03:53:12] <zeeshan> and now its making reasonable parts diameter wise
[03:53:28] <zeeshan> the z-axis is still 0.002" , still trying to figure out if its the fixed support, or the ball nut
[03:53:48] <archivist> iirc little finger on top of column moves the pointer full scale http://www.collection.archivist.info/searchv13.php?searchstr=Mercer+comparator
[03:53:49] <zeeshan> after im happy with that, ill put a solid tool post and retry the cnmg vs ccmt test
[03:54:15] <zeeshan> lol .00001
[03:54:18] <zeeshan> :]]
[03:55:12] <archivist> something like a 2" column bending with the weight of the base being the only reaction
[03:55:37] <zeeshan> yea just do bending of beams math
[03:55:44] <zeeshan> and youll see quickly how much stuff deflects
[03:55:49] <zeeshan> steel is like E = 210Gpa
[03:55:53] <zeeshan> thats all you really need
[03:56:11] <zeeshan> stuff might not fail
[03:56:17] <zeeshan> but it certainly deflects!
[03:56:53] <archivist> the paper roller I did suffered from bending
[03:57:49] <archivist> and when the roller has a crown against the bend the circumference varies therefore wrinkling the paper
[03:58:35] <archivist> use backing rolls for the pressure, and parallel for contact
[03:58:38] <zeeshan> so precvis e:D
[03:59:16] <zeeshan> is that the most precise indicator you have?
[03:59:26] <zeeshan> ive never seen a .0001
[03:59:27] <zeeshan> ive never seen a .00001
[03:59:36] <zeeshan> i have a .00005
[04:00:53] <archivist> I also have the digimatic which is reasonable and covers 2" travel
[04:00:53] <zeeshan> wow its 5am
[04:00:55] <zeeshan> i need to go o sleep
[04:01:02] <zeeshan> nice
[06:35:45] <miss0r|shop> Can someone tell me what this 'Driver Microstepping' is? (configuering the axis)
[06:50:14] <_methods> http://linuxcnc.org/docs/html/config/stepconf.html#_axis_configuration_a_id_sec_axis_configuration_a
[06:50:17] <_methods> like that
[06:51:16] <archivist> miss0r|shop, chose something sensible, high numbers may be smoother but not more accurate, lower means faster
[06:51:58] <miss0r|shop> I've read the link, but I still have no idea what it is
[06:52:24] <_methods> Driver Microstepping - The amount of microstepping performed by the driver. Enter 2 for half-stepping.
[06:52:43] <_methods> so if you put in 4 that would be quarter-stepping
[06:52:54] <_methods> 8 = 1/8 stepping
[06:53:03] * miss0r|shop is reading up on half stepping and quarter stepping
[06:53:20] <Praesmeodymium> the driver chips themselves do a cheat thing that allows for between full step motions of a stepper motor this is usually configurable via jumpers or switches
[06:53:36] <_methods> what drivers are you using?
[06:54:15] <miss0r|shop> CW-5045
[06:54:56] <_methods> looks like a dqm542
[06:55:12] <miss0r|shop> let me get this straight. I can make it "hold" inbetween steps?
[06:55:27] <miss0r|shop> with this have more than the 200 steps/rev the motor specifies?
[06:55:39] <archivist> best hold is full step
[06:55:53] <_methods> you should read up on steppers
[06:55:56] <miss0r|shop> but I am understanding this correct? :)
[06:55:58] <archivist> but that is also worst for resonance
[06:56:00] <_methods> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Stepper_Drive_Timing
[06:56:31] <archivist> it is a compromise
[06:56:39] <_methods> at the bottom of the page are teh settings for your stepper driver
[06:57:23] <miss0r|shop> _methods: Thanks, i already have thoes settings :) I just need to read up on the stepper more
[06:57:28] <_methods> http://www.orientalmotor.com/technology/articles/step-motor-basics.html
[06:57:37] <_methods> they have a cool little gif
[06:57:42] <_methods> that shows how the stepper coils work
[06:58:14] <_methods> explanations of 2 phase and 5 phase steppers
[06:59:19] <archivist> a happy medium of resonance v speed can be 8 micro steps but your system can be different
[06:59:24] <miss0r|shop> I guess this is only interresting if I want higher resolution
[06:59:28] <_methods> yes
[06:59:40] <_methods> or more speed but less torque
[06:59:55] <archivist> resolution does not mean accuracy though, be very careful
[07:00:01] <miss0r|shop> more speed? by skipping over coils?
[07:00:12] <miss0r|shop> archivist: indeed.
[07:00:20] <archivist> less resonance means more speed
[07:00:46] <_methods> incresead speed with partially energized coils
[07:00:49] <archivist> but you cannot go fast on a parralel port
[07:01:21] <miss0r|shop> I am going to stop asking questions for now. I will just read the page ;)
[07:02:08] <_methods> well that page is on the in depth side there are many good overviews that relate more closely to cnc applications
[07:02:25] <miss0r|shop> I like to know the details
[07:02:44] <_methods> then that page is probably a good start
[07:03:59] <archivist> and this page http://www.micromo.com/microstepping-myths-and-realities
[07:05:17] <miss0r|shop> heh, i've already had a few aha-moments
[07:06:37] <_methods> yeah i half step on my minimill and that's it
[07:07:10] <_methods> it's funny when my buddy comes over he's one of those 3d printer clowns and he cries and cries about the noise
[07:07:21] <_methods> apparently 3d printer people have sensitive ears
[07:07:32] <miss0r|shop> hehe
[07:09:07] <archivist> _methods, I went through a few tests when setting up the hobbing setup, noise is very noticeable at various speeds
[07:09:32] <miss0r|shop> when my roland mill is running noone can hear the steppers due to the cutting. I can see how 3D print people would care about the noise. also, most of them have the printer in their parents basement(fact) :)
[07:09:50] <archivist> or bedroom
[07:09:59] <miss0r|shop> running while you sleep :)
[07:10:09] <miss0r|shop> or in some cases, apparently, don't sleep
[07:10:31] <archivist> steppers "singing" you to sleep
[07:11:17] <miss0r|shop> I had a 3-axis CHINA(yes, so chinese it needs to be written like that) that made a horrible noise dragging the table around.
[07:15:31] <_methods> yeah i'm used to machine shop noise so little steppers talking don't really offend my ears
[07:15:57] <_methods> and LOL at the basement crack
[07:18:16] <_methods> this is kinda cool
[07:18:19] <_methods> http://www.lucadentella.it/en/2015/02/28/un-piccolo-cnc-bot/
[07:19:16] <_methods> http://www.piccolo.cc/
[07:19:32] <miss0r|shop> thats damn tiny
[07:19:37] <_methods> pretty useless but still cool
[07:23:14] <_methods> good little portable "cnc" tool for doing demos
[07:25:46] <Swapper> http://en.wikipedia.org/wiki/Metrication_in_the_United_States
[07:26:33] <_methods> In 1875, the United States solidified its commitment to the development of the internationally recognized metric system
[07:28:46] <Swapper> http://time.com/3633514/why-wont-america-go-metric/
[07:29:43] <Swapper> i where only curious why :)
[07:29:54] <_methods> it's insane
[07:30:02] <Swapper> apperently the US Army is all metric ?
[07:30:13] <_methods> yeah all the services should be
[07:30:35] <_methods> the real problem lies in the construction industry
[07:30:37] <Swapper> so all shops delivering army related parts need to do them metric :)
[07:30:52] <_methods> they refuse to give up imperial
[07:30:56] <Swapper> yea they mentioned that in the time article
[07:31:31] <_methods> most of the guys in construction used every ounce of brain power they possess to learn to read one type of tape maesure
[07:31:47] <_methods> asking them to learn to use another tape measure is just too much
[07:32:07] <Tom_itx> ulgh, more snow... 19F
[07:32:08] <_methods> civil engineers just really are the dumbest engineers
[07:32:36] <Tom_itx> they move rocks
[07:32:42] <_methods> indeed
[07:32:52] <_methods> in imperial
[07:33:15] <_methods> they worked hard to move it 2 feet
[07:33:55] <Swapper> hehe
[07:35:25] <archivist> they mine 800 ton blocks of marble
[07:35:47] <_methods> with machines made by mechanical engineers
[07:36:06] <archivist> have to move it to see where to slice before they take out of the mine
[07:36:25] <_methods> hehe i just like to make fun of CE's
[07:36:37] <cpresser> "and the wine and spirits industry abandoned fifths for 75-milliliter bottles." <-FAIL!
[07:36:56] <cpresser> 750ml it is. 75ml is like a double shot.
[07:37:41] <Tom_itx> it just sounds wrong to ask for a fourth of whiskey!
[07:38:07] <SpeedEvil> Is there a 3d printer channel?
[07:38:13] <_methods> unfortunately
[07:38:14] <Tom_itx> reprap
[07:38:18] <Tom_itx> unfortunately
[07:38:26] <Tom_itx> it's nearly as bad as electronics
[07:38:32] <_methods> or #ubuntu
[07:38:33] <archivist> that is spelled repcrap
[07:38:48] <SpeedEvil> I've been wondering about a glass printer
[07:38:49] <_methods> it's a place full of special
[07:39:12] <SpeedEvil> That is - a printer that prints glass - not using it as a structural element
[07:39:20] <_methods> yeah a guy made one
[07:39:23] <_methods> solar
[07:39:25] <_methods> sand
[07:39:28] <_methods> =
[07:39:29] <_methods> glass
[07:39:37] <SpeedEvil> No, I mean 'proper'
[07:39:51] <_methods> well that would be interesting
[07:39:54] <SpeedEvil> As in produces nice glass objects - with admittedly some 'grain'
[07:40:09] <SpeedEvil> Basically 3d printer in a kiln
[07:40:28] <_methods> i'm about 100% sure no 3d printer channel will have the help you need with this project
[07:40:32] <SpeedEvil> yeah
[07:40:53] <_methods> they can barely handle squishing plastic out in formed shapes
[07:40:58] <Swapper> maybe some kind of sinter method ?
[07:41:01] <Swapper> with laser
[07:41:09] <SpeedEvil> Swapper: no, I mean very normal 3d printing.
[07:41:21] <SpeedEvil> Swapper: Just with the hot end at 1000C or so.
[07:41:30] <_methods> inconel nozzle lol
[07:41:46] <Swapper> quite special to create somthing that withstand 1000c and thats that small and controllable
[07:41:48] <archivist> glass dreams
[07:41:57] <SpeedEvil> Laser sintering is way easier
[07:42:26] <Swapper> a silica sand bed that is melted with laser
[07:42:33] <Swapper> could that work ?
[07:44:28] <SpeedEvil> you'd need to use borosilicate, I suspect
[07:44:52] <SpeedEvil> Or heat the bed significantly - to several hundred C - otherwise the cooling will shatter it
[07:45:23] <Swapper> but that problem you would have anyhow? even if you "extruded" the glass
[07:45:26] <Swapper> and formed it
[07:46:14] <SpeedEvil> yes.
[07:50:07] <jthornton> http://ibin.co/1tfMBbpqnOBP
[07:50:46] <jthornton> http://ibin.co/1tfMMDzV4lKs
[07:53:36] <Jymmm> arc of/for?
[07:55:07] <_methods> cool
[07:55:11] <_methods> you got it working good
[08:14:13] <JT-Shop> getting there, I can create G2/3 from the coordinates and diameter of the arc then send the profile to a file and load it in Axis
[08:14:50] <JT-Shop> you can type in linear moves then add an arc etc
[08:15:12] <JT-Shop> last phase is to integrate the roughing code for the profile
[08:15:42] <JT-Shop> and it is all done in python with Gtk
[08:26:21] <_methods> nice work
[08:28:40] <_methods> if only i had a linuxcnc lathe now lol
[08:28:58] <_methods> after i finish the x2 i'm doing a plasma table thoug
[08:29:02] <_methods> need that first
[08:29:04] <_methods> then lathe
[08:29:22] <_methods> just be stuck cranking handles for a bit longer
[08:30:40] <archivist> graver and hand rest should be good enough :)
[08:30:52] <_methods> hehe
[08:44:00] <Swapper> im redoing the cnc of my old X2, its fun to make parts for a mill and not doing the parts on the same machine... :)
[08:44:14] <Swapper> sooo much easier
[08:50:13] <_methods> yeah
[08:50:15] <JT-Shop> I'm thinking now that I don't even need to bother with GladeVCP it just makes it more complicated to code
[08:50:48] <JT-Shop> I can just pop the program up and I'm using axisremote to load the file so I'm GTG
[09:32:02] <_methods> yeah i might do a 7040 before i do the lathe
[09:32:17] <_methods> those machines look quite a bit better and around the same footprint as my x2
[09:32:36] <Swapper> yea a bit sturdier and a lot more travel
[09:32:48] <Swapper> i got my hands on a RF45 "XL" type mill
[09:32:52] <Swapper> a Luna 500
[09:33:06] <Swapper> about the same travel
[09:33:11] <_methods> as the 7040?
[09:33:16] <Swapper> yea
[09:33:25] <_methods> is the 7040 and the rf45 basically the same thing?
[09:33:37] <Swapper> the R45 is more rigid
[09:33:46] <_methods> ah i might do the rf45 then
[09:35:01] <Swapper> its G0704 you mean ?
[09:35:05] <Swapper> http://www.g0704.com/
[09:35:25] <Swapper> you might mean some other mill
[09:35:48] <_methods> yeah
[09:35:53] <_methods> g0704
[09:35:57] <_methods> i got dyslexia
[09:35:58] <_methods> lol
[09:36:05] <Swapper> i thaught it where that one :)
[09:36:37] <_methods> where did you get your rf45
[09:37:18] <Swapper> local "craigs list"
[09:37:21] <Swapper> called blocket
[09:37:24] <_methods> oh wow
[09:37:43] <Swapper> payed like 500$ for it
[09:37:53] <Swapper> it where a bit roached
[09:38:06] <Swapper> but now its fully cnc with AC servos :)
[09:38:13] <Swapper> doing 5m/min
[09:38:19] <_methods> well that's a score and a half
[09:38:24] <_methods> i paid that much for my turd x2
[09:38:33] <Swapper> yea i payed more for the X2 new
[09:38:41] <Swapper> about 600
[09:40:21] <_methods> wish i had more room in the garage i'd just get a bridgeport
[09:41:32] <Swapper> i wish i had lots more room, the mill takes like 25% :)
[09:41:39] <Swapper> but it works
[09:41:44] <Swapper> its only hoby
[09:41:48] <_methods> yeah
[09:42:38] <_methods> will be nice if i can get a few jobs that pay so i can add on to the garage and put some real machines in
[09:43:48] <archivist> what is a paying job
[09:43:59] <_methods> one that nets profit lol
[09:44:59] * JT-Shop has 467 parts and 40 weldments to make
[09:45:19] <_methods> soemthing like that
[09:46:08] <archivist> I currently have 0 to make :(
[11:00:55] <ssi> morn
[11:22:04] <CaptHindsight> rather than not crashing the machine, the customer now wants extra actuators and parts so that they can replace them :)
[11:22:15] <ssi> ha
[11:23:49] <CaptHindsight> first they broke the motor to screw couplings, now they broke the not on the screw
[11:24:00] <CaptHindsight> not/nut
[12:40:24] <Connor> CaptHindsight: Which machine is this ?
[12:43:11] <CaptHindsight> it's a gantry robot
[12:43:29] <Connor> Why would the be crashing ?
[12:43:53] <Connor> Does it not have limit switches ?
[12:43:56] <archivist> user participation
[12:44:14] <_methods> hehe
[12:45:49] <XXCoder> heys
[12:46:46] <zeeshan> im trying to get more rapid speeds out of my lathe
[12:47:07] <zeeshan> can someone help me see if im calculating this stuff right
[12:47:40] <Connor> What's to calculate.. turn the IPM up till it stalls than back down 20 or 30 %
[12:47:53] <zeeshan> well
[12:47:59] <zeeshan> i need to see if im anywhere close to theoretical
[12:48:02] <zeeshan> i feel like im not.
[12:48:47] <Connor> Your have a torque curve for your stepper ?
[12:48:55] <zeeshan> on Z i got: 5mm pitch ball screw (5.102 threads per inch), direct drive..
[12:49:02] <zeeshan> im using 1/4 stepping
[12:49:07] <archivist> you dont want to get near theoretical if you want to remain in control
[12:49:23] <zeeshan> http://www.kelinginc.net/KL34H2120-42-8AT.pdf
[12:49:27] <zeeshan> yea i think its like that
[12:49:30] <zeeshan> archivist: i know
[12:49:36] <zeeshan> i need a starting point
[12:50:00] <archivist> a starting point is losing steps, back off a lot
[12:50:01] <zeeshan> using that chart, to convert pps to rpm
[12:50:13] <zeeshan> you gotta do ie [3000 pps / 200 ]* 60?
[12:50:23] <zeeshan> cause theres 200 pulses per rev?
[12:50:39] <zeeshan> so 3000 pps = 900 RPM
[12:50:43] <Connor> correct
[12:50:55] <zeeshan> okay now thats in human units
[12:51:12] <Connor> you want to stay in the 2000 to 3000 pps range.
[12:51:57] <zeeshan> 900/5.102 = 176 ipm
[12:52:05] <zeeshan> i can't seem to get more than 90 ipm on the Z
[12:52:18] <zeeshan> i feel like the double ball nut
[12:52:23] <zeeshan> is causes some serious friction
[12:52:27] <zeeshan> i had a hard time turning that thing by hand
[12:52:31] <zeeshan> the X axis was a lot smoother
[12:52:47] <Connor> Is this one double nutted ?
[12:52:54] <zeeshan> both are double nutted right now
[12:53:00] <zeeshan> but the x went on smoothly by hand
[12:53:06] <zeeshan> the Z needed some torquing.
[12:53:09] <Connor> also, the stupid seal adds extra friction
[12:53:10] <zeeshan> its hard to turn it by hand
[12:53:17] <zeeshan> whcih ones?
[12:53:19] <zeeshan> on the mounts?
[12:53:25] <Connor> the ones on the bearing blocks.
[12:53:32] <FinboySlick> zeeshan: You are driving your big mill with steppers?
[12:53:37] <zeeshan> FinboySlick: no
[12:53:38] <Connor> but, your saying the nut itself is hard to turn?
[12:53:38] <zeeshan> my lathe
[12:53:45] <zeeshan> yes connor
[12:53:52] <zeeshan> with the single ball nut
[12:53:59] <zeeshan> i could rapid only at 120 ipm
[12:54:02] <zeeshan> not close to 176
[12:54:14] <zeeshan> so maybe i have multiple problems
[12:54:16] <Connor> take the seals off the bearing block.
[12:54:22] <Connor> or, it could be binding..
[12:54:34] <Connor> you have both ends fixed ?
[12:54:38] <zeeshan> nah one is floating
[12:54:52] <Connor> floating in air, or in a block?
[12:54:55] <zeeshan> block
[12:55:02] <Connor> so, you could still bind.
[12:55:26] <zeeshan> should i try floating it?
[12:55:29] <Connor> try taking the seals out of the bearing block first.
[12:55:30] <zeeshan> without the block
[12:55:47] <Connor> to eliminate any source of friction.
[12:56:07] <Connor> How hard is it to turn the ballnut on the screw itself.. (without turning the screw.. just rotate the nut)
[12:56:15] <zeeshan> quite hard, i cant do it by hand
[12:56:20] <zeeshan> i had to put a nut at the end of the ball screw
[12:56:30] <zeeshan> and turn the ball nut in a vise
[12:56:34] <zeeshan> after i got it on
[12:56:37] <Connor> Something is wrong then.
[12:56:41] <zeeshan> it still takes a good amount of force
[12:56:44] <Connor> WAY wrong.
[12:56:59] <Connor> you should be able to turn that ball not with 2 fingers.
[12:57:00] <CaptHindsight> Connor: they can crash it into anything in the work envelope
[12:57:16] <CaptHindsight> same as a mill or lathe
[12:57:17] <Connor> CaptHindsight: Idiots.
[12:57:26] <zeeshan> connor do you remember what you had your accel set to?
[12:57:35] <CaptHindsight> limit switches don't limit their ability to break it
[12:57:41] <Connor> No I don't.. but, that doesn't matter.. your missing what I'm saying..
[12:57:53] <zeeshan> connor no i took that into my brain
[12:58:00] <zeeshan> im making a list of things to check :)
[12:58:16] <zeeshan> my x axis is ratioed 2.7:1
[12:58:17] <Connor> if you remove the ballscrew from the bearing blocks.. hold the screw, and turn the nut.. it should turn freely..
[12:58:35] <Connor> with 1 or 2 fingers..
[12:58:49] <zeeshan> so only 333 rpm available, 65 ipm
[12:58:55] <zeeshan> but im rapiding that thing at 100 ipm
[12:59:14] <Connor> if it doesn't.. something major wrong.. too large of balls.. grit... or the whipers on the nut are too tight. or all the above.
[12:59:16] <zeeshan> connor yea my x axis ball nut moves ewasly
[12:59:23] <zeeshan> wipers i put on after
[12:59:38] <zeeshan> i think the balls might be too big
[12:59:45] <zeeshan> ill have to go throug hthe pain staking process of measuring them all
[12:59:59] <Connor> Did you replace them ?
[13:00:07] <Connor> and was it like this with the original nut ?
[13:00:19] <zeeshan> no, the original single nut was easy to turn
[13:00:22] <zeeshan> with 2 fingers
[13:01:01] <Connor> OKay. So.. is this the one you had to reload the balls in?
[13:01:04] <zeeshan> yea
[13:01:15] <Connor> okay. It's possible you have a ball out of the circuit.
[13:01:50] <Connor> also, you and test to see if it's the preload of both nuts by taking the 2nd one off.. just put it on a tube.
[13:02:00] <archivist> missing ball=more space, extra ball?
[13:02:24] <archivist> dual nuts inline?
[13:02:26] <_methods> ball trapped between races = no space
[13:02:36] <Connor> archivist I'm thinking ball just outside of the circuit preventing one of them circuits from circulating at all.
[13:02:49] <archivist> and then sliding
[13:03:13] <Connor> archivist yes. the LMB2008 style with tabs to keep them rotating together.
[13:03:20] <archivist> the tubes should not allow that to happen
[13:03:35] <Connor> No tubes. internal races.
[13:03:48] <Connor> with plastic returns.
[13:05:13] <zeeshan> i think im gonna do it like this:
[13:05:19] <zeeshan> remove ball nut and floating support
[13:05:35] <zeeshan> turn ball screw in the fixed mount and see if it is easy to rotate
[13:05:45] <zeeshan> then check end play
[13:05:57] <Connor> you just told me you had to use the vise...
[13:06:06] <Connor> to turn the nut on the screw...
[13:06:11] <zeeshan> yea initially
[13:06:21] <zeeshan> itll be a bitch take it off
[13:06:28] <zeeshan> but i can do it
[13:06:30] <Connor> okay.. I'm saying.. that's way to hard.
[13:06:43] <Connor> something is wrong with the circuit in the ballnuts.
[13:06:46] <zeeshan> yea for sure, i acknowledged that
[13:06:54] <zeeshan> im just need to also make sure i dont have backlash issue
[13:07:01] <zeeshan> this axis i was originally getting 4.5 thou backlash
[13:07:03] <zeeshan> w/ the single nut
[13:07:14] <zeeshan> but i think a lot of that is coming from the fixed support
[13:07:24] <Connor> then don't frack around.. take the nut off and repack it again.. and make sure you don't allow a ball to jump out of the circuit..
[13:07:32] <zeeshan> how do you do that? :p
[13:07:35] <zeeshan> i used tons of grease
[13:07:47] <zeeshan> each circuit had about 1/2 a ball gap in it
[13:07:50] <zeeshan> after i fulled packed em
[13:08:01] <Connor> that could be part of the issue too.
[13:08:05] <Connor> too MUCH grease.
[13:08:17] <Connor> and you could still have had a single ball jump a circuit.
[13:08:37] <zeeshan> how do you stop that :)
[13:08:45] <ssi> do it better.
[13:08:49] <Connor> Yup. :)
[13:09:05] <zeeshan> should there be gap in each circuit?
[13:09:06] <Connor> Also, remember when I said they match the nut to the screw? It could be that too.
[13:09:13] <Connor> yea. that's fine.
[13:09:18] <zeeshan> so i got lucky with X axis?
[13:09:24] <Connor> could be.
[13:09:46] <Connor> You can also test by taking the nut without the flange off (be sure to use the tube they came on)
[13:09:52] <Connor> and see how hard it is to turn.
[13:10:10] <Connor> if it freely turns after that one comes off.. they have too much preload.
[13:10:59] <Connor> and you would need to adjust by grinding those clips down.
[13:11:34] <Connor> oh hell.. you don't even have to take the nut off.. you can just remove the screws and pull the clips..
[13:11:50] <zeeshan> i think to make this work better
[13:11:56] <zeeshan> ill assemble the nut without the flange on by itself
[13:12:01] <zeeshan> and then the flanged nut by itself
[13:12:13] <zeeshan> then make them meet on the ball screw
[13:12:30] <zeeshan> and then see if i can get them to line up
[13:12:31] <Connor> Well.. pull the clips first and test.
[13:12:39] <Connor> that might be all you need to do..
[13:12:43] <zeeshan> yea
[13:12:56] <Connor> is take a few .0001 off the clips.
[13:15:42] <zeeshan> will mess around with it tonight
[13:15:42] <zeeshan> :)
[13:16:50] <miss0r|shop> I am configuering a cw-5045 stepper controller for a 3A/phase stepper. The closest I can come is 2,8 or 3,2A. What mshould I choose?
[13:17:20] <_methods> 3.2
[13:17:21] <Connor> 3.2
[13:17:25] <_methods> more = better lol
[13:17:33] <Connor> The motor won't pull more than it's rated..
[13:17:43] <zeeshan> it wont? :D
[13:17:47] <miss0r|shop> yeah, but if I set it to 4,5A it will fry?
[13:19:09] <miss0r|shop> it also has a full/half power. is that just to make the scale have choices or does it mean something else?
[13:19:26] <miss0r|shop> current... full/half current
[13:19:38] <Connor> No. Think of it like plugging a 3amp fan into a 15amp wall socket..
[13:20:00] <Connor> the fan will pull what it's rated for. and no more.
[13:20:25] <Connor> That sounds like a idle current selection.. I turn that on.
[13:20:28] <Rab> miss0r|shop, from the datasheet: " Automatic half current option for power saving and reduction in standby temperature"
[13:20:29] <miss0r|shop> hmm... I thought the stepper controller regulated the voltage to get the current you set it for
[13:20:38] <miss0r|shop> rab, thanks
[13:21:09] <zeeshan> i have 6A steppers
[13:21:13] <zeeshan> i have it set to 5.4A
[13:21:17] <zeeshan> i should prolly step it up to 6.1A
[13:21:27] <zeeshan> get a bit more performance out of em
[13:21:56] <Rab> miss0r|shop, I believe the half current option only applies when the driver isn't actively stepping. Less holding torque, but lower power and cooler operation as they say.
[13:22:43] <ssi> someone buy me this
[13:22:46] <ssi> http://www.barnstormers.com/classified_954575_Grumman+Albatross.html
[13:22:54] <ssi> HOUSEBOATPLANE
[13:23:06] <zeeshan> youve been watching too much expendables
[13:23:06] <_methods> oh damn
[13:23:06] <zeeshan> haha
[13:23:09] <_methods> dats pimp
[13:23:16] <Rab> I have the same understanding of voltage/current with respect to stepper drivers. I wouldn't set over 100% of the rated current.
[13:23:18] <ssi> albatross is a truly absurd airplane
[13:23:34] <ssi> won't fit in any hangar on our airport
[13:23:43] <ssi> biggest hangar we have is an 80' door, 90' clear span
[13:23:49] <ssi> albatross is 92' wingspan, 65' long
[13:24:05] <zeeshan> Connor: your theory about the fan is slightly off :P
[13:24:12] <ssi> it's twice the size of my house
[13:24:14] <_methods> includes 2 spare engines lol
[13:24:21] <ssi> yeah
[13:24:22] <zeeshan> you're right that it'll draw whatever current it needs if you give it a certain voltage
[13:24:27] <ssi> and they're R1820 1450hp radials too hahah
[13:24:33] <ssi> bastard holds 2000 gallons of fuel
[13:24:33] <Rab> If you're running at the rated voltage for the motor, it'll draw under the limit. If you're using a much higher voltage with a chopper driver, I think you'd better adjust the driver to the rated current or below.
[13:24:37] <ssi> the wing is 22' off the ground
[13:24:38] <zeeshan> but if you add extra load on that fan, , itll draw more current
[13:24:38] <ssi> ABSURD
[13:24:51] <zeeshan> but fans are a slightly different beast cause they're impedance matched
[13:25:02] <Cromaglious> ssi, you can't stick it on rollers and angle it in?
[13:25:12] <ssi> doubt it
[13:25:12] <miss0r|shop> rab i'm running at 36V on 5V steppers
[13:25:16] <miss0r|shop> so, below it is :)
[13:25:44] <Rab> miss0r|shop, right, I would choose 2.8A.
[13:25:50] <Cromaglious> Albatross is such an ugly plane it's pretty
[13:26:05] <_methods> ssi: i thought you were linking to an albatross d III
[13:26:07] <zeeshan> rab you think 200mA
[13:26:10] <_methods> http://en.wikipedia.org/wiki/Albatros_D.III
[13:26:12] <zeeshan> is gonna make a diff ;p
[13:26:13] <zeeshan> er
[13:26:18] <zeeshan> 400 mA
[13:26:38] <zeeshan> like in my case 6A/phase , i set it to 6.1A instead of 5.4A
[13:26:38] <ssi> _methods: that wouldn't be quite as comfortable of a house
[13:26:40] <ssi> and a TERRIBLE boat :D
[13:26:42] <_methods> no lol
[13:26:44] <zeeshan> .100 mA will fry it? :D
[13:26:48] <zeeshan> .100A
[13:26:50] <Rab> zeeshan, do you think the rating on the motor is a falsehood?
[13:26:51] <_methods> but great for shooting down brits
[13:27:00] <zeeshan> Rab: yes
[13:27:01] <ssi> so long as they're in camels
[13:27:05] <_methods> heheh
[13:27:06] <zeeshan> first of all it doesnt tell you the duty cycle
[13:27:08] <DaViruz> i'd like to have a l39 albatros
[13:27:13] <zeeshan> that it is at
[13:27:15] <Rab> If you want equipment to last, you derate it.
[13:27:26] <ssi> I've flown an L39 actually hahahah
[13:27:29] <DaViruz> oh
[13:27:34] <zeeshan> for example, an induction motor can easily take twice the fla
[13:27:36] <zeeshan> for short periods
[13:27:41] <ssi> they're fun, but i wouldn't own one
[13:27:46] <zeeshan> my servo motors have a s3 rating
[13:27:53] <zeeshan> 20% 50%
[13:27:53] <zeeshan> etc
[13:27:57] <DaViruz> from what i understand they're pretty cheap to own for a jet
[13:28:10] <ssi> yeah it's the absolute cheapest way to have a "fighter jet"
[13:28:59] <DaViruz> i have a model one with a turbine, that'll have to suffice
[13:29:18] <ssi> eesh RC turbines cost more than some real airplanes :P
[13:30:03] <Cromaglious> ssi hehe L39 flown by the patriots... home ported at Byron Airport.. Worst just jet show ever
[13:30:20] <ssi> lol yeah they're pretty marginal as jets go
[13:30:23] <DaViruz> this one isn't that bad though, i'm about $5k in i'd guess
[13:30:45] <Cromaglious> What year is the Grumman HU-16?
[13:30:59] <ssi> DaViruz: https://pbs.twimg.com/media/B8yE-jWIgAAduWf.jpg:large I've got $15k in that :P
[13:31:03] <ssi> Cromaglious: 1956
[13:31:27] <Cromaglious> nice mid production
[13:32:42] <ssi> DaViruz: here ya go http://www.barnstormers.com/classified_793081_Aero+Vodochody+L-39+Albatros.html
[13:32:48] <ssi> I've seen that airplane in person a few times
[13:33:04] <DaViruz> that's not too bad
[13:33:12] <ssi> nah they're cheap to acquire
[13:33:17] <ssi> not cheap to maintain or run tho :)
[13:34:43] <Cromaglious> Cheaper to build a composite BD-5, I know a guy with Molds for a Composite BD-5 fuselage in San Antonio
[13:34:45] <ssi> idle 68gph, takeoff 350gph, climb 200gph, low alt cruise 170gph, high alt cruise 140gph @ 340kt
[13:34:54] <ssi> that's... awful
[13:35:03] <ssi> Cromaglious: there's a BD-5J for sale in tennessee
[13:35:06] <ssi> for like 20k
[13:35:10] <mozmck> There are a couple of BD-5 kits around here for sale.
[13:35:13] <ssi> they won't sell it to anyone unless they can demonstrate proficiency... somehow
[13:35:23] <Cromaglious> ssi stretched?
[13:35:38] <Cromaglious> BD-5 has terrible wings
[13:35:41] <ssi> dunno... the J model is the jet
[13:35:42] <Rab> ssi, what's that weird fan between the landing gear?
[13:36:05] <DaViruz> that's the propeller!
[13:36:14] <ssi> Rab: on what?
[13:36:26] <Rab> On the L-39: http://barnstormers.com/tmp_images/e5/dd/.watermarked_feaf6437a9e8101178c4f613e155a48b.jpg
[13:36:44] <Cromaglious> Emergency power
[13:36:46] <ssi> slipstream alternator probably
[13:36:51] <ssi> yeah
[13:37:26] <archivist> propulsion when floating on the sea
[13:37:26] <Cromaglious> gives you power if you have a flame out and the turbines stop turning
[13:37:43] <ssi> yeah the L39 is a single
[13:37:47] <ssi> one of its big weaknesses
[13:37:52] <Cromaglious> hopefully you have enough height to restart
[13:38:14] <Cromaglious> or some place not to expensive to land or plant
[13:38:28] <ssi> here's another bede for sale
[13:38:29] <ssi> http://www.barnstormers.com/classified_983658_BD-5+Microjet.html
[13:39:15] <DaViruz> that's too cute
[13:39:29] <ssi> yeah on a scale of one to totes, they're totes adorbs
[13:39:40] <Cromaglious> ssi think BD-5 with a wing profile of a DC-3 wing root NACA 2520 I think and a T tail
[13:40:01] <_methods> octopussy
[13:40:36] <ssi> I have an airplane design rolling around in my brain
[13:40:54] <ssi> imagine a spitfire planform, scaled down to about a 22-24' wingspan
[13:41:03] <Cromaglious> 16 degree angle of attack instead of 5, and tail is flying even on take off vs a Bede-5 Loft into air on Ground effect and hopefully your flying before you crash
[13:41:04] <ssi> single seat and powered by a 180-200hp lyco
[13:41:09] <ssi> retract
[13:41:28] <ssi> I want it to do better than 300mph on less than 14gph
[13:42:32] <Cromaglious> well the composite bd-5 (CS-100) would max out at around 230 on a Rotax 80hp
[13:42:54] <ssi> yeah it's not hard to do on tiny airplanes
[13:43:07] <ssi> the nemesis formula 1 plane does 292mph on 100hp O-200
[13:45:52] <_methods> how much is hangar rental typically?
[13:46:02] <ssi> it's all over the map
[13:46:11] <ssi> I pay nominally $300 per t-hangar
[13:46:23] <ssi> the more rural you get, the cheaper it gets
[13:46:32] <ssi> if I wanted to be closer to the city, it'd be two or three times higher
[13:46:39] <_methods> and you keep your machines there?
[13:46:43] <ssi> yeah
[13:46:47] <ssi> I have three T-hangars
[13:46:52] <_methods> sounds like a great deal
[13:46:56] <_methods> for that amount of space
[13:46:56] <ssi> and one of them is an end unit, so there's ahalf-hangar extra space
[13:46:58] <_methods> at that price
[13:47:03] <ssi> I pay $850 for 3.5 hangars
[13:47:14] <_methods> that quite a bit of sq footage
[13:47:18] <ssi> it is
[13:47:23] <_methods> for that rate
[13:47:25] <_methods> damn
[13:47:26] <ssi> but airplanes take up a lot of space awkwardly
[13:47:29] <_methods> yeah
[13:47:34] <Connor> 3.5 hangers ?
[13:47:41] <ssi> I want to move into a box hangar
[13:47:44] <_methods> still finding commercial space that large
[13:47:46] <_methods> for that low
[13:47:46] <ssi> they're 80x90 I think
[13:47:48] <_methods> good luck
[13:48:01] <ssi> the people in them currently are paying $1000/mo, but if I want one it's mysteriously $1500
[13:48:04] <ssi> pisses me off
[13:48:10] <ds3> what city are you paying $850 for 3.5 hangers?
[13:48:18] <ssi> atlanta
[13:48:23] <ssi> but 30 miles outside the city
[13:50:27] <ssi> "Although Bede had suggested using the B wings,[13] the earliest kits shipped only with the short "A" wings. All four examples completed with these wings crashed on their first flight, three on takeoff and one lasted long enough to crash on landing. In three of the four crashes, the pilots were killed. "
[13:50:32] <ssi> spectacular
[13:51:21] <Connor> ssi: ICK
[13:51:36] <ssi> Connor: that's the nature of the game :)
[13:51:58] <DaViruz> by the forth maiden you'd think they'd see a pattern
[13:52:18] <_methods> i'm sure all their wives were happy lol
[13:52:41] <_methods> oh honey that sounds like a great hobby
[13:52:47] <_methods> just make sure you get a good policy
[13:53:11] <ssi> don't forget I'm the moron who intends to build and testfly an aircraft of my own design :D
[13:53:40] <ssi> but it's ok cause I'm not married
[13:53:45] <DaViruz> you're also the moron who burned your house down with a home built laser cutter ;)
[13:53:45] <_methods> someone has to get the camera crews out of the news station
[13:53:52] <ssi> yussss
[13:54:28] <ssi> and I'm about to start building mk2 laser cutter
[13:55:27] <Cromaglious> even the stretch BD-5s with the honda engines don't have enough angle of attack...
[13:55:33] <DaViruz> was anything salvageable from the old laser?
[13:55:40] <DaViruz> salvegeable?
[13:55:44] <DaViruz> what a bothersome word
[13:55:46] <ssi> yeah, I had the linuxcnc configs in git :D
[13:55:49] <DaViruz> :D
[13:55:52] <_methods> hahahah
[13:56:05] <_methods> i need to do that too
[13:56:07] <ssi> probably worth more than any single component
[13:56:07] <Cromaglious> I'll take a DC3 wing profile anyday of the week...
[13:56:10] <ssi> if you factor my time
[13:56:49] <ssi> I think I'm gonna do an 80W reci tube this time, instead of the 100W I had before
[13:57:14] <_methods> oh yeah?
[13:57:23] <_methods> why you going with that?
[13:57:38] <ssi> well, cost and availability mostly
[13:57:50] <ssi> the company I bought my last tube from keeps some in stock in california
[13:57:58] <ssi> it's $115 to ship a tube from CA, or $430 to ship from hong kong
[13:58:01] <miss0r|shop> ´So when nothing works when i¨ve wired up stuff amd am trying off X axis steper. All I can get from it is a minute buzz
[13:58:12] <ssi> the 80W is $625, and the 100W is $1000
[13:58:18] <_methods> ahh
[13:58:19] <ssi> they have 80W on hand, but no 100W
[13:58:22] <ssi> so that makes it DOUBLE
[13:58:35] <_methods> well if the 80w does what you need.........
[13:58:42] <ssi> well also, lasers are weird
[13:58:49] <ssi> and I felt like I never could really fully use the power I had
[13:58:49] <_methods> no shit lol
[13:59:03] <ssi> most materials I was cutting, turning up the power didn't do anything but make the edges more charred
[13:59:05] <_methods> is it a particle or is it a wave lol
[13:59:06] <Tom_itx> sure you can handle 100w ?
[13:59:20] <ssi> my speed limits were mostly based on depth of field
[14:00:04] <ssi> that said, I am going to build this table to accomodate longer lenses
[14:00:08] <ssi> longes practical lens on my last table was 3"
[14:00:14] <ssi> I'd like to be able to run as long as 8"
[14:02:15] <Swapper> miss0r|shop: what driver are you using and voltage?
[14:02:35] <ssi> also it seems like some commercial chinese machines are set up with dual tubes
[14:02:37] <Tom_itx> is newegg in memphis?
[14:02:47] <ssi> so what I'm thinking is do an 80W tube now, and later I can get a second 80W tube and a beam combiner
[14:02:55] <ssi> and have more power for the same money as a 100W tube
[14:03:33] <Swapper> is that C02 tubes or what does recti mean ?
[14:03:47] <ssi> reci is a brand; they're DC-excited CO2 tubes
[14:03:53] <Swapper> ok
[14:04:04] <_methods> Tom_itx: their distribution is i think
[14:04:15] <_methods> i've gotten stuff from newegg memphis before
[14:04:29] <Tom_itx> 2 items coming from there
[14:04:34] <Swapper> what sort of lasers does comercial steel cutting lasercutters use?
[14:04:44] <_methods> beam combiner?
[14:04:54] <_methods> they use co2
[14:05:02] <_methods> 2000w+
[14:05:13] <_methods> the laser at my shop is a little one it's only 3200w
[14:05:13] <Swapper> ok
[14:05:25] <_methods> trumpf makes their own resonator
[14:05:38] <_methods> fanuc, trumpf, and mitsubishi are the big players
[14:05:48] <ssi> I want a "little one" that's only 3200W :)
[14:05:56] <_methods> heheh
[14:06:12] <_methods> fanuc supplies resonators to 3rd party manufacturers like amada
[14:06:15] <ssi> I would love to be able to do a metalcutting laser, but it's not easy to do with DC CO2 lasers :(
[14:06:20] <_methods> no
[14:06:28] <_methods> it's not a simple thing
[14:06:31] <_methods> lots of power
[14:06:36] <_methods> vacuums
[14:06:44] <ssi> there are people advertising 150W CO2 lasers that will cut thin sheet
[14:06:46] <Tom_itx> i imagine you need to be a bit more careful with those
[14:06:47] <ssi> but I'm suspicious
[14:06:49] <ssi> based on my experiments
[14:07:06] <_methods> well i think as a hobbiest if you want to do metal you need to get one of these cheap chinese yag's
[14:07:10] <ssi> I never got around to trying oxygen assist, but 120W scratched 28ga mild, and no more
[14:07:13] <_methods> they're only like $40k
[14:07:19] <ssi> "only"
[14:07:23] <ssi> what about fiber lasers?
[14:07:26] <_methods> well in the laser world that is dirt cheap
[14:07:30] <ssi> I don't know much about anything other than CO2 lasers
[14:07:30] <Tom_itx> how do you get past the 'reflective' surface of the metal?
[14:07:34] <_methods> those yags are fiber
[14:07:38] <ssi> ah ok
[14:07:44] <_methods> Tom_itx: you don't
[14:07:44] <ssi> Tom_itx: reflective is subjective :)
[14:07:52] <miss0r|shop> It seems I have wired everything the way I am supposed to. When I turn on the power, all the steppers lock in, and they are unturnable by hand. When I try to move them with linuxcnc, they move perhaps 1 step to each side, and when I try to turn them by hand afterwards, it is possible... with some efford thou. I can't get them to spin properly. Does this sound like an error you have encountered
[14:07:52] <miss0r|shop> ?
[14:07:52] <_methods> it reflects back and blows up your lens
[14:07:57] <ssi> metal is reflective to 10.6um, but less subjective to 1000nm, which is what yag is
[14:07:59] <_methods> it's why you can't cut copper
[14:07:59] <Tom_itx> heh
[14:08:00] <_methods> brass
[14:08:12] <_methods> and why aluminum is problematic
[14:08:14] <ssi> s/subjective/reflective/
[14:08:15] <ssi> lul
[14:08:18] <Tom_itx> even if you lead the lense?
[14:08:22] <Tom_itx> angle it..
[14:08:24] <_methods> alum in it's molten state is highly reflective
[14:08:51] <_methods> well then the beam would just bounce off
[14:09:20] <_methods> the goal is to quickly create a molten puddle and use gas to push it throuhg
[14:09:26] <_methods> like a shaped charge
[14:09:27] <Tom_itx> do they coat the metal with something before cutting?
[14:09:29] <Tom_itx> to dull it
[14:09:32] <_methods> i have before
[14:09:35] <_methods> milk of magnesia
[14:09:43] <_methods> for problem aluminum before
[14:10:18] <ds3> does MoM work for cutting brass/copper?
[14:10:21] <_methods> but the yags will cut copper and bass
[14:10:34] <_methods> not that i know of
[14:10:38] <XXCoder> _methods: that made me wonder how good telescope molen alum would be
[14:10:40] <_methods> i've never tried the mom thing on that
[14:10:46] <ssi> they make high power laser mirrors out of copper
[14:10:48] <ssi> tihnk about that :)
[14:10:52] <XXCoder> some guy made telescope out of liquid mecury
[14:11:00] <_methods> yeah most of our bend optics are copper
[14:11:06] <XXCoder> it was amazing effective but in heavy protection and it only points up
[14:11:12] <_methods> actually all of the bend optics are lol
[14:11:17] <ds3> _methods: how many watts did you have to cut a MoM coated piece of alum?
[14:11:29] <ssi> my little baby co2 laser uses all silicon mirrors and ZnSe lenses
[14:11:37] <_methods> i have no idea i just used mom as an assisst for aluminum that was being a bitch
[14:11:56] <ds3> i must try MoM
[14:11:57] <_methods> yeah all of our bend optics are water cooled copper mirrors
[14:12:18] <ds3> wonder if that helps with cutting SS too
[14:12:31] <ssi> _methods: can you get me a spare resonator? :D
[14:12:33] <_methods> i've never really had a problem with ss
[14:12:35] <_methods> hahah
[14:12:44] <ssi> like when jdh's company was throwing a bunch away? :P
[14:12:45] <_methods> shit the resonator on the trumpf is like $40k
[14:13:08] <ssi> yag efficiency is really low isn't it?
[14:13:09] <_methods> i think that's for a rebuilt one lol
[14:13:13] <ssi> what's the input power like for 3200W?
[14:13:19] <_methods> i think they're improving the yags
[14:13:29] <ssi> co2 is like 10%, I feel like yag is closer to 1%
[14:13:33] <_methods> something to do with improved solid state emitters
[14:13:35] <_methods> but i'm not sure
[14:14:02] <_methods> i know trumpf is making a huge push on the solid state lasers
[14:14:08] <ssi> diode pumped yag is approaching 40% apparently
[14:14:09] <ssi> that's awesome
[14:14:27] <_methods> yeah
[14:14:42] <_methods> and the beam path is so much shorter and a straight line
[14:14:49] <Swapper> miss0r|shop: are any of the axies working ?
[14:15:11] <Swapper> does the drivers have a standby mode that lowers the power ?
[14:15:18] <miss0r|shop> Swapper: Same syndrome for all axis
[14:15:28] <miss0r|shop> Swapper: it does, but I dissabled it
[14:15:31] <ssi> _methods: are your machines flying optic, rectilinear motion?
[14:15:50] <_methods> flying optic
[14:16:21] <Swapper> miss0r|shop: do you have a scope ? :)
[14:16:25] <miss0r|shop> Swapper: In linux cnc the enable amplifyer is the same as just enable axis, right?
[14:16:49] <miss0r|shop> Swapper: I do. but I promised the wife I would be back in the house in 30 mins, and I would just love to have something moving before i go :)
[14:16:56] <_methods> you shouldn't be able to turn any at all by hand once you've enabled it
[14:17:13] <Swapper> miss0r|shop: ill check my enable
[14:17:45] <Swapper> net z-enable hm2_5i25.0.7i77.0.0.output-14
[14:17:50] <Swapper> but i have mesa cards
[14:17:54] <Swapper> dont know what you have
[14:18:04] <miss0r|shop> cw-5045 stepper driver
[14:18:14] <_methods> breakout board?
[14:18:24] <Swapper> paralell port?
[14:18:36] <miss0r|shop> a RATTM v5 breakoutboard
[14:19:05] <miss0r|shop> for par port, yes
[14:20:45] <_methods> ew gross the manual is all full of mach3
[14:21:14] <miss0r|shop> _methods: you're old enough to ignore that part ;)
[14:21:19] <_methods> hehe
[14:21:28] <zeeshan> we can never ignore mach
[14:21:38] <zeeshan> =]
[14:21:42] <Swapper> miss0r|shop: when i have tested steppers i have taken a arduino with some step generating code
[14:21:46] <Swapper> only to be able to test
[14:21:57] <ssi> zeeshan: MUST STAMP IT OUT
[14:22:07] <zeeshan> lol
[14:22:28] <miss0r|shop> indeed. I could do that. But with my somewhat limited time, I would just love to satisfy my childish need to see motors spin
[14:22:30] <ssi> zeeshan: I forget, do you solidworks?
[14:22:34] <Swapper> miss0r|shop: you have the right voltages and all that checked?
[14:22:47] <miss0r|shop> yep
[14:22:50] <Swapper> power to the bob ?
[14:22:51] <zeeshan> yes
[14:22:57] <ssi> on 2015?
[14:22:58] <archivist> ssi a few do
[14:23:05] <miss0r|shop> Swapper: yes.
[14:23:13] <Swapper> any leds on the driverS?
[14:23:16] <_methods> so did you wire it active low?
[14:23:53] <miss0r|shop> Swapper: a red and a green. The green is on :)
[14:24:02] <zeeshan> 2013
[14:24:02] <miss0r|shop> _methods: yep
[14:24:07] <zeeshan> need to upgrade to 2015
[14:24:11] <ssi> yes you do
[14:24:16] <archivist> why
[14:24:19] <ssi> I may want to share what I'm working on with you and foce you to help me
[14:24:21] <Swapper> miss0r|shop: so the enable works from linuxcnc ?
[14:24:26] <ssi> did I say force? I meant beg
[14:24:29] <Swapper> or you have it "hot wired"
[14:24:36] <zeeshan> like on modeling it?
[14:24:39] <archivist> downgrade so we can all play
[14:24:48] <zeeshan> archivist: arent you on 2006 still
[14:24:50] <zeeshan> hehehe
[14:24:57] <ssi> more like static analysis
[14:24:57] <zeeshan> best version!
[14:25:10] <zeeshan> ssi i dont trust solidworks simulation
[14:25:17] <archivist> 2004 was pretty damned good
[14:25:20] <zeeshan> just a recent example
[14:25:21] <miss0r|shop> Swapper: The enable works... hotwired? it has common positive and controls on negative
[14:25:27] <zeeshan> i was doing pull stud comparison in ansys
[14:25:32] <zeeshan> and abaqus and solidworks
[14:25:38] <zeeshan> using same meshing
[14:25:51] <zeeshan> for some reason solidworks outputs a smaller max psi number
[14:25:56] <zeeshan> havent figured out why
[14:25:57] <ssi> vell you can do the math by hand if you prefer :D
[14:25:57] <Swapper> miss0r|shop: with hotwired i meant forced it on by putting voltage directly to enable
[14:26:02] <_methods> maybe try going common negative?
[14:26:03] <Swapper> to force it on all the time
[14:26:26] <zeeshan> ssi math by hand ftw!
[14:27:04] <Swapper> http://duxe.ru/images/opto_mont_800.jpg
[14:27:13] <Swapper> not that i can read rushian
[14:27:15] <miss0r|shop> Swapper. I have not :)
[14:27:36] <Swapper> but atleast thats the driver ?
[14:27:46] <miss0r|shop> Swapper: these are reversed. i.e. They have to be low when they are enabled
[14:27:48] <Swapper> you got the coils right ?
[14:27:59] <Swapper> from the motors ?
[14:28:01] <miss0r|shop> Swapper: Check on the coils
[14:28:18] <miss0r|shop> I havent measured on it thou. I used the colors from the manual. hang on - doing measurement
[14:28:19] <zeeshan> do you guys have issues
[14:28:20] <Swapper> been a while since i wired mine but cant you connect those 2 diffrent ways ?
[14:28:24] <Swapper> 1 for more holding
[14:28:26] <zeeshan> with pulleys rotating on flats?
[14:28:39] <Swapper> 1 for more holdingpower
[14:28:39] * zeeshan hates flats so much
[14:28:57] <Swapper> bipolar
[14:29:08] <Swapper> unipolar
[14:29:28] <miss0r|shop> well, I only have 4 wires, so theres not much to mess up
[14:29:39] <Swapper> you can connect it diffrently
[14:29:55] <miss0r|shop> indeed. I have the coils connected correctly
[14:30:16] <Swapper> have u checked the steping delays ?
[14:30:18] <JT-Shop> 50-50 sleet and snow now :(
[14:30:23] <miss0r|shop> well - it SEEMS like that is also in order - something is obviously not
[14:30:41] <miss0r|shop> Swapper: stepping delays?
[14:31:50] <Swapper> cant come up with the right term
[14:31:57] <Swapper> the delay that the driver needs for a step
[14:32:03] <Swapper> anyone know what i mean ?
[14:32:53] <miss0r|shop> 'step time' 'step space' 'direction setup' 'direction hold' ect?
[14:33:14] <Swapper> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Stepper_Drive_Timing
[14:33:15] <Swapper> yes
[14:33:17] <Swapper> thats it
[14:33:26] <miss0r|shop> i've set that acording to the manufacture
[14:33:27] <Swapper> but probably not the fault
[14:33:29] <Swapper> in your case
[14:33:29] <ssi> z I'm just gonna draw a simple weldment frame for this table and see how it deflects and stuff
[14:33:32] <ssi> or something
[14:34:02] <Swapper> miss0r|shop: check last row on that URL
[14:34:07] <Swapper> thats your driver ?
[14:34:14] <zeeshan> ssi
[14:34:14] <zeeshan> http://plasmamotion.com/assets/images/Plasma_Table_Sm0202.jpg
[14:34:15] <miss0r|shop> yes
[14:34:16] <zeeshan> something like this?
[14:34:33] <miss0r|shop> that exact page I used for into
[14:34:37] <miss0r|shop> info*
[14:35:18] <zeeshan> http://www.diycraftshome.com/wp-content/uploads/2014/12/5-sharp39-x-2-sharp39-plasma-cutting-table-with-a-funnel-design-under-it-to-direct-all-the-dust-debris-and-slag-into-a-metal-pail..jpg
[14:35:21] <zeeshan> great looking plasma table
[14:35:25] <zeeshan> but do you know whats wrong?
[14:35:29] <ssi> hm
[14:35:30] <zeeshan> all that work and a fundamental mistake
[14:35:42] <ssi> no motion? :P
[14:35:48] <ssi> oh it's just a hand-cut table
[14:35:52] <zeeshan> hes dumping hot metal sparks into a galvanized bucket
[14:35:52] <zeeshan> wtf
[14:35:56] <zeeshan> he/she
[14:36:01] <zeeshan> :D
[14:36:02] <ssi> just put water in it
[14:36:16] <zeeshan> i hate galvanizing
[14:36:18] <zeeshan> that stuff is aids
[14:36:28] <ssi> it's not that bad
[14:36:31] <XXCoder> what will hot sparks do to galvanized bucket
[14:36:36] <Swapper> miss0r|shop: weerd that the steppers looses torque after a move
[14:36:39] <ssi> release zinc fumes
[14:36:40] <ssi> makes you sick
[14:36:49] <ssi> just have to drink milk to chelate :D
[14:36:50] <XXCoder> oh yea zinc flu
[14:36:52] <zeeshan> haha
[14:36:55] <_methods> then you'll really need that MoM
[14:37:01] <Swapper> miss0r|shop: have you checked the voltage to the drivers while testing ?
[14:37:02] <zeeshan> ssi i think if you can figure out
[14:37:07] <zeeshan> how much your gantry weighs
[14:37:13] <ssi> gantry is LIGHT
[14:37:18] <ssi> I'm gonna do makerslide again; that worked out well
[14:37:21] <zeeshan> you can get a starting value of how strong the frame needs to be
[14:37:35] <ssi> and I'm gonna do it across the short axis this time
[14:37:40] <miss0r|shop> Swapper: http://cnc4you.co.uk/resources/CW5045.pdf <- I want it to use full-step. Wouldn't you agree that the config should be sw5: 0 sw6: 0 sw7: 0 sw8: 0 ?
[14:37:41] <ssi> the last table was 2x4, and the gantry was 4'
[14:37:46] <ssi> this one will be 4x8, and 4' gantry
[14:37:52] <_methods> yeah
[14:37:52] <Praesmeodymium> is makerslide going to be that much stronger than say hiwin clone? they are about the same cost last I looked
[14:37:57] <miss0r|shop> Swapper, I have not. 2 sec
[14:37:59] <zeeshan> big stuff gets a big hard
[14:38:06] <ssi> Praesmeodymium: got a link?
[14:38:06] <zeeshan> cause the metal beams start sagging under their own weight
[14:38:11] <ssi> zeeshan: yes exactly
[14:38:15] <ssi> that's why I need my pet ME
[14:38:31] <zeeshan> 1 thou accuracy in height?
[14:38:41] <zeeshan> do you even need it that precise
[14:38:45] <ssi> not really
[14:38:55] <miss0r|shop> Swapper: supply voltage = rock steady
[14:39:00] <zeeshan> prolly 20 thou would be acceptable
[14:39:01] <ssi> 10 thou is probably a good target
[14:39:02] <zeeshan> in height
[14:39:11] <ssi> I used to use jo blocks for focus setup
[14:39:14] <zeeshan> x and y would be nice to have less than a thou
[14:39:19] <ssi> and you could be 50 thou off and do ok
[14:39:25] <_methods> miss0r|shop: do you have pics of how you have it wired up
[14:39:27] <zeeshan> yea
[14:39:30] <Praesmeodymium> http://www.aliexpress.com/store/product/Kossel-Mini-MGN12-12mm-miniature-linear-rail-slide-3pcs-12mm-L-1000mm-rail-3pcs-MGN12H-carriage/239992_2044492004.html
[14:39:38] <_methods> from the motor to the driver to the bob
[14:39:53] <XXCoder> 3 peices?
[14:39:59] <ssi> Praesmeodymium: that's a bit expensive
[14:40:01] <XXCoder> tri rail or one each axis?
[14:40:08] <Praesmeodymium> thats a vendor some of the 3dprinter resellers use so the the stuff is generally good
[14:40:09] <_methods> it's for a kossel/delta
[14:40:13] <ssi> and I need like 2800mm
[14:40:36] <zeeshan> have you seen the rail designs
[14:40:38] <Praesmeodymium> ahh yeah shipping from china will kill any cost savings on that kind of length
[14:40:39] <zeeshan> where you take a square beam
[14:40:40] <ssi> the makerslide stuff is pretty cheap
[14:40:45] <zeeshan> and mount it in a diamond formation
[14:40:48] <zeeshan> i dig that
[14:40:53] <ssi> I can get 1800mm and 1000mm pieces for $38 adn $22 respectively
[14:40:56] <XXCoder> im thinking about grabbing this http://www.aliexpress.com/item/3040-CNC-router-milling-machine-mechanical-kit-CNC-aluminium-alloy-Frame-ball-screw-for-DIY-user/2051273724.html
[14:41:00] <XXCoder> what do you guys think
[14:41:20] <ssi> what I did last time was just buy a shapeoko kit for $300 and then buy some long pieces of rail, and use their carriage plates and bearings/wheels etc
[14:41:23] <ssi> it worked out pretty well
[14:41:25] <zeeshan> XXCoder: that lookjs worth it in its weight in aluminum
[14:41:25] <zeeshan> lol
[14:41:28] <Praesmeodymium> ssi: actually once you get the carriage and the wheels and the eccentrics etc, I preced 3 meters of makerslide and those 3 meters of hiwin and the hiwin was 20$ cheaper
[14:41:48] <XXCoder> zee yea I think I will buy it once my money stuff stabilizes after new job settles down
[14:41:49] <ssi> yeah possibly
[14:42:06] <ssi> hm igus has some plastic linear rail components, maybe I should look at them
[14:42:14] <ssi> I need almost no load capacity
[14:42:14] <Praesmeodymium> I thought about that method for a 1mx1m wood engraver, the shapeoko kit
[14:42:17] <Cromaglious> ugh ER11 collets runout 0.0006 sheeshz 6 tenths
[14:42:35] <zeeshan> what kind of ghetto collets are th ose
[14:42:35] <zeeshan> !
[14:42:36] <Cromaglious> that's a $20 set
[14:42:52] <zeeshan> 6 tenths isnt that bad
[14:43:01] <ssi> ER11 implies small cutters
[14:43:03] <Cromaglious> and a $26 set
[14:43:03] <ssi> small cutters HATE runout
[14:43:27] <Cromaglious> and a $35 set
[14:43:43] <_methods> yeah put a .8mm end mill in there
[14:43:54] <_methods> those 6 tenths will kill ya
[14:44:28] <ssi> yep
[14:44:38] <_methods> funny callin something .8mm an end mill hehe
[14:44:53] <_methods> .5mm end mill
[14:45:01] <XXCoder> .0005 em :P
[14:45:07] <XXCoder> *mm
[14:45:09] <ssi> that's a lot more than I expected
[14:45:09] <_methods> now that's tiny
[14:45:12] <ssi> http://www.mscdirect.com/product/details/08018616?src=pla&cid=PLA-Google-PLA+-+Test&CS_003=7867724&CS_010=08018616
[14:45:45] <_methods> should be cheaper from igus i would think
[14:46:25] <ssi> yeah might be
[14:46:33] <ssi> I had a little box of samples of igus stuff they sent me
[14:46:36] <ssi> and those were in there
[14:46:38] <_methods> yeah
[14:46:39] <XXCoder> _methods: http://www.mmsonline.com/articles/cutting-with-a-0001-inch-end-mill
[14:46:41] <Cromaglious> I picked up some 3/6 shank 0.008 and 0.025 end mills
[14:46:43] <_methods> i have one of those
[14:46:51] <Cromaglious> 3/16" shank
[14:47:03] <_methods> cool little samples
[14:47:08] <XXCoder> 0.0254 mm
[14:47:17] <_methods> they sent me a cool sample kit
[14:47:23] <_methods> with screwdrivers and stuff
[14:47:24] <ssi> on like a 4" rail :)
[14:47:25] <ssi> it was about the size of a 12 or 15mm thk rail
[14:47:25] <ssi> and would be more than adequate for the laser
[14:47:25] <ssi> there's this stuff too, but it's not as nice
[14:47:25] <ssi> http://www.igus.com/wpck/3587/drylin_n?C=US&L=en
[14:47:25] <ssi> it's like drawer slides
[14:47:47] <_methods> yeah i used that stuff on my 3d printer
[14:47:49] <_methods> one of them
[14:48:24] <XXCoder> "100 millionths of an inch"
[14:49:35] <ssi> that's just a tenth :P
[14:49:48] <XXCoder> yeah
[14:50:20] <ssi> now that's not bad
[14:50:30] <XXCoder> "When machining is completed, the blocks are deburred by hand at a bench under a microscope. Burrs are gently removed with the ground tip of a bamboo chopstick or other type of wood. All edges must be dead sharp. No nicks or edge rollover is allowed. The edges cant be touched by human hands at this point, Mr. Janzen says, because particles of skin left behind by contact can damage mating surfaces when the blocks are assembled."
[14:50:33] <ssi> $65.55 for a 2800mm rail with two trucks
[14:50:41] <ssi> for the igus plastig-bearing profile rails
[14:50:44] <XXCoder> pretty precise. way more precise what my work tend to be
[14:51:08] <ssi> oh wait I think that's just the rail
[14:51:11] <ssi> the trucks are $35 apiece
[14:51:35] <ssi> $254 for the rail and two trucks is what they're quoting me... weird
[14:51:56] <ssi> that's way too much
[14:52:01] <XXCoder> welcome to weird world of high precision. Keep the lights on. The Space Instrument Shop never goes dark because heat from ceiling lights affects ambient shop temperature.
[14:53:21] <Cromaglious> XXCoder, do they have air blenders on the heating ducts to keep the air exactly the right temp?
[14:53:33] <XXCoder> article dont say.
[14:53:47] <XXCoder> they however, say near lights is turned off quickly to keep temp even
[14:53:58] <XXCoder> look at my link above
[15:01:20] <JT-Shop> now it's 150% snowing
[15:01:34] <XXCoder> so sky is 150% snow
[15:02:57] <ssi> all the weldment profiles for steel rect tube that they supply are way too heavy
[15:03:04] <ssi> sry they = solidworks
[15:04:07] <Swapper> would it be worth it to put linear ways on a Rf45 style mill ?
[15:04:11] <Swapper> even possible ?
[15:05:19] * Tom_itx shoves his pile of snow on JT-Shop's place
[15:05:29] <Cromaglious> hmm on a Rong Fu... Anything is possible. You'd probably need a another mill to do the milling for the conversion
[15:05:45] <Swapper> yea probably yea
[15:06:02] <ssi> lightest tube metal supermarket has is 1/8" wall, which'd probably be fine
[15:06:13] <ssi> 110" piece of 4x2x.125" is about $40
[15:07:38] <_methods> ssi did you load the weldment profiles in solidworks?
[15:08:02] <ssi> yea
[15:08:12] <ssi> I know it's trivial to edit them, I'm just complaining :)
[15:08:21] <_methods> no under toolbox
[15:08:27] <ssi> yeah I know, I did
[15:08:28] <_methods> there are more profiles
[15:08:32] <_methods> oh ok
[15:08:36] <ssi> there's an ansi-inch, tube (rectangular) category
[15:08:44] <ssi> and TR4x2x0.1875 is the lightest one
[15:08:46] <_methods> yeah most people don't know about all that
[15:08:59] <ssi> without loading from toolbox there's like three profiles and they're all 1/4" Wall
[15:09:03] <_methods> they just think the ones defualt loade are it
[15:09:05] <_methods> yeah
[15:13:59] <ssi> ugh... I have NO IDEA how to unset read-only permissions on the weldment profiles folder in windows
[15:14:28] <_methods> i just copy it
[15:14:33] <_methods> then make custom
[15:14:36] <ssi> I can't
[15:14:47] <ssi> sw won't save anything into that folder
[15:14:47] <_methods> copy that profile to your own folder
[15:14:52] <_methods> don't use that folder
[15:14:59] <ssi> if I do that, I don't know how to make it show up in the dropdowns
[15:15:05] <_methods> go into settings
[15:15:06] <CaptHindsight> think of them as templates and make copies
[15:15:10] <_methods> one sec
[15:15:48] <_methods> options>file locations
[15:16:04] <_methods> then in dropdown select weldment profiles
[15:16:12] <_methods> and add your custom folder to locations
[15:16:23] <ssi> aha thanks
[15:16:26] <_methods> np
[15:16:54] <Cromaglious> hmmm tool setting touch plate... Wondering how to make a wiper to hit the end mill when it comes in to set...
[15:17:03] <_methods> i personally save all those profiles from the main one to my custom folder
[15:17:08] <_methods> then move it between installations
[15:17:17] <Swapper> Connor: cant you use air?
[15:17:25] <ssi> yeah that's probabyl wise
[15:17:31] <ssi> I save my drawings in Dropbox
[15:17:32] <Connor> Huh?
[15:17:36] <ssi> I should add a profiles location there too
[15:17:39] <Swapper> hav seen renisaws that have air nozle
[15:17:41] <_methods> yeah
[15:17:53] <_methods> if you make a lot of custom profiles or hardware
[15:17:56] <_methods> or punch tools
[15:18:03] <_methods> iz gud idea
[15:18:24] <Swapper> Connor: meant Cromaglious
[15:18:29] <Swapper> sorry
[15:18:35] <Cromaglious> I wonder if G31 will do G31 Z-1 X-.5 and come down at an angle
[15:18:46] <_methods> since soliworks tends to be silly about takin in old toolbox/profile info
[15:20:15] <Cromaglious> thinking about using a http://www.ebay.com/itm/NEW-CNC-Router-Mill-Z-Axis-Tool-Setting-Touch-Plate-works-w-Mach3-FREE-SHIP-/221636469672?pt=LH_DefaultDomain_0&hash=item339a9023a8
[15:20:56] <Swapper> Cromaglious: that only a pice of metal in a delrin pice
[15:21:09] <Cromaglious> wanna put a bit wiper on there so I could screw it to the table and have the machine do auto tool height
[15:21:13] <Swapper> you can make that from some bolts and a cutting board :)
[15:21:40] <Cromaglious> true... i have bolts and delrin... I need a wiper idea
[15:22:00] <CaptHindsight> Swapper: the dovetail ways are linear on the rongfu45's, you you mean change them out to some type of crossed roller bearing?
[15:22:16] <CaptHindsight> -you
[15:22:31] <Swapper> yea rails with blocks
[15:22:36] <Swapper> bearing blocks
[15:23:13] <CaptHindsight> Swapper: you can but why? Bridgeports use dovetail ways and last and work for decades
[15:23:39] <Swapper> less resitance, tighter ?
[15:24:03] <Swapper> or is it only any idea to use linear ways to get speed?
[15:24:29] <CaptHindsight> if I really wanted to get the most out my RongFu and the metal wasn't pure garbage, I'd just true them up and keep them lubed and adjusted
[15:24:47] <XXCoder> Alien with HULK powers lol http://gaspull.geeksaresexytech.netdna-cdn.com/wp-content/uploads/2015/02/life3.jpg
[15:25:05] <Swapper> not that easy to true ways upp is it ?
[15:25:10] <Cromaglious> hmm gotta see if the er11 nut is conductive enought
[15:25:21] <CaptHindsight> Swapper: depends on why they are out
[15:25:44] <Swapper> mine is quite scratched at the bottom surface
[15:25:58] <Swapper> dont know what the effects of that is
[15:26:45] <_methods> increase lube reservoir lol
[15:26:56] <_methods> more scratches more lube lol
[15:27:07] <_methods> free upgrade
[15:27:22] <CaptHindsight> Swapper: have they been scraped?
[15:27:36] <Swapper> i do have a probably dumb question, the mill i have have 2 bolts holding the "gib" and it can be adjusted, then i have setscrews that pushes in on the gib, i guess these are only to lock the axis when manualy milling ?
[15:27:47] <Swapper> CaptHindsight: there are scrapemarks
[15:27:49] <CaptHindsight> http://s113340019.onlinehome.us/don/cnc2678/E4103394.JPG scraped ways
[15:28:05] <Swapper> they are scraped
[15:28:10] <CaptHindsight> http://mikalsmachinerepairandscraping.com/images2/100_0635-L.jpg
[15:28:53] <Swapper> i wish mine looked as good as the first picture :)
[15:29:00] <CaptHindsight> once you get the ways under 0.001" the next thing is going to be the spindle bearings
[15:29:11] * furrywolf can't imagine ever doing anything that precise by hand
[15:29:14] <CaptHindsight> and the twisting of the frame
[15:29:19] <Swapper> i got AC bearings
[15:29:26] <Swapper> changed the rollers
[15:29:49] <Swapper> runs fine at 7200rpm - 8k
[15:30:05] <Swapper> but dont know if i have the right preload or anytin :)
[15:30:37] <CaptHindsight> http://www.hossmachine.info/rf-45_clone.html
[15:31:08] <Swapper> mine is a tad bigger
[15:31:30] <Swapper> https://www.netauktion.se/uploads/extrabilder158876_center.jpg
[15:31:38] <Swapper> not mine but the same mill
[15:31:42] <Cromaglious> got it... I have a Stainless steel spring at X-5mm and Y-5mm of the tool set location. er11 nut comes down and hits spring, it keeps going down until contact at tool setter. set tool height, g0 Z -0.1, g0 X5mm Y5mm
[15:32:01] <Swapper> https://www.netauktion.se/uploads/extrabilder158879_large.jpg
[15:32:19] <Cromaglious> I mount the spring on a block of delrin
[15:32:24] <XXCoder> http://makezine.com/2015/03/03/x-carve-inventables-launches-new-line-of-cnc-machines/
[15:32:27] <XXCoder> wonder if any good
[15:33:06] <Swapper> looks a tad weak
[15:33:14] <Swapper> maybe as plasma cutter :)
[15:33:23] <XXCoder> wood its fine
[15:33:24] <CaptHindsight> just a power feed on the X, so I wouldn't bother with trying to change any bearings
[15:33:28] <Swapper> but shure, for engraving
[15:33:47] <Swapper> CaptHindsight: thats not my mill
[15:33:57] <Swapper> CaptHindsight: mine is all CNCed w
[15:34:25] <CaptHindsight> I still wouldn't bother
[15:34:38] <Swapper> its allready in there
[15:34:46] <Swapper> and it made a world of differeance
[15:35:17] <CaptHindsight> XXCoder: that junk has been around for a while
[15:35:25] <XXCoder> yeah 800 not worth it
[15:35:33] <XXCoder> since I already has everything but frame
[15:35:46] <XXCoder> the my previous link aliexpress frame should work fine
[15:35:54] <CaptHindsight> http://www.automationtechnologiesinc.com/products-page/cnc-router/cnc-mogul-machine
[15:36:29] <XXCoder> CaptHindsight: http://www.aliexpress.com/item/3040-CNC-router-milling-machine-mechanical-kit-CNC-aluminium-alloy-Frame-ball-screw-for-DIY-user/2051273724.html
[15:38:22] <adoyle88> hello everyone. I've read through the suggested materials that you guys gave me yesterday. I've got the Debian Wheezy LinuxCNC image installed and I've been playing around with halcmd
[15:38:51] <CaptHindsight> XXCoder: they just don't know enough or care enough to properly fix the ballscrews
[15:39:10] <XXCoder> yeah but its cheap and good enough for me to fix it
[15:39:15] <adoyle88> I used encoder and the clock from siggen to succesfully count and add up a simulated position
[15:40:17] <adoyle88> now I want to use an input from my break out board to trigger the encoder count. I've got it hooked up, made a parport component but watching the pin value in halmeter shows that I'm not getting a signal
[15:41:31] <adoyle88> whats the best way to see if my parallel port is even working?
[15:43:38] <_methods> manually turn a pin on and off and measure voltage on it?
[15:43:53] <CaptHindsight> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Parallel_Port_Tester
[15:44:01] <_methods> or that lol
[15:44:19] <adoyle88> that's awesome
[15:44:22] <CaptHindsight> but your idea using a meter is better :)
[15:44:36] <CaptHindsight> use both
[15:44:45] <CaptHindsight> it's just any easy way to toggle pins
[15:45:03] <CaptHindsight> and if the LPT driver isn't loaded it won't work
[15:48:43] <adoyle88> By default, all of my inputs are green. That doesn't seem right to em
[15:48:44] <adoyle88> me*
[15:48:55] <JT-Shop> adoyle88, http://linuxcnc.org/docs/html/hal/basic_hal.html
[15:48:56] <adoyle88> how would I check if the LPT driver is installed?
[15:49:28] <adoyle88> I've read that a few times. And I've done the advanced tutorial as well
[15:50:05] <JT-Shop> load the parallel port driver in hal, if it does not bitch it is working
[15:50:25] <JT-Shop> adoyle88, did you read the part about adding your function to a thread?
[15:50:59] <JT-Shop> http://linuxcnc.org/docs/html/hal/parallel_port.html
[15:51:21] <adoyle88_> I typed this one "loadrt hal_parport cfg="0"" and it did not complain
[15:53:54] <JT-Shop> that's a 3rd of it
[15:55:21] <JT-Shop> seems the manual doesn't go into detail about adding the functions to a thread
[15:55:45] <JT-Shop> http://linuxcnc.org/docs/html/hal/parallel_port.html#_functions_a_id_sub_parport_functions_a
[15:56:41] <JT-Shop> so until you add the read and write functions to a thread the parallel port driver does nothing
[15:57:06] <XXCoder> CaptHindsight: besides wonky screw mount what ya think of that frame
[15:58:11] <adoyle88_> @JT-Shop I bet that is what's wrong
[15:58:40] <adoyle88_> the test showed that everything is fine. I'll go back to my hal stuff and add the read and write functions. Thanks for your help
[16:01:02] <CaptHindsight> XXCoder: beware of crunchy bearings
[16:01:19] <XXCoder> indeed I plan to pull it all apart, clean oil then back together
[16:01:47] <XXCoder> I had to clean my sbr blocks too lol so crunchy
[16:03:10] <Swapper> i have a bad sound from my z axis, its like tumping when going up and down
[16:03:17] <Swapper> wonder if its the bearings
[16:03:26] <XXCoder> http://hackaday.com/2015/03/02/the-hard-drive-midi-controller/
[16:03:30] <JT-Shop> stupid cell phone keeps giving me a winter weather warning... it's friggin blizzard out there... I can see that without the cell phones help
[16:03:35] <XXCoder> orrrr cnc controller
[16:03:42] <XXCoder> pediant?
[16:04:02] <XXCoder> no clicks though so harder
[16:04:34] <Swapper> yea detents is a must ?
[16:05:17] <XXCoder> detents?
[16:05:35] <Swapper> on the midi controller
[16:05:46] <Swapper> and using that as pendant for cnc
[16:05:52] <Swapper> would be not so good without detents
[16:05:54] <XXCoder> oh that clicky thing when turning
[16:06:13] <XXCoder> yea guess it wont work
[16:06:23] <XXCoder> it probably could spin which is very bad thing lol
[16:06:38] <Swapper> the weel keeps spining, and on a cnc that means the axies keeps spining = not good :)
[16:06:48] <XXCoder> yep
[16:07:02] <Swapper> but real cool implementation
[16:07:14] <Swapper> its like a quadrature encoder
[16:07:18] <Swapper> in those motors
[16:07:24] <XXCoder> wonder how precise it is
[16:07:29] <XXCoder> rotation encoder
[16:07:35] <Swapper> https://www.youtube.com/watch?v=bHgAbA7qq0w
[16:07:58] <CaptHindsight> Chinese bearings with random detents
[16:08:20] <XXCoder> 8 point dont sound accurate
[16:08:36] <XXCoder> does someone speak of how accurate it is?
[16:08:36] <CaptHindsight> they may be used for audible confirmation that they are in fact spinning
[16:09:00] <Swapper> its a BLDC motor isnt it ?
[16:09:09] <Swapper> but it can be used as a simple encoder
[16:09:15] <Swapper> but the precision cant be good
[16:09:28] <XXCoder> no idea if anyone spoke on video, no autocaptions and me deeefy lol
[16:09:30] <Swapper> its like using a RC plane BLDC as an encoder
[16:09:47] <adoyle88_> good news everyone! My encoder counter works with the parallel port signal
[16:09:57] <Swapper> XXCoder: no speaking
[16:10:02] <Swapper> only blip sounds
[16:10:08] <XXCoder> lol ok
[16:10:15] <XXCoder> adoyle88_: nice. for your bender?
[16:10:20] <Deejay> gn8
[16:11:02] <XXCoder> gonna get ready for work later
[16:11:13] <adoyle88_> yeah. It's for the rotary encoder we are putting on the bend axis to bend to a certain degree
[16:11:51] <Swapper> gn8
[16:25:20] <furrywolf> argh! it's too hot outside to get anything done.
[16:26:37] <furrywolf> I was working on caulking windows, but it's flat out too hot to be on a ladder in the sun.
[16:27:23] <furrywolf> ... I don't know how hot. my weather station seems to have stopped updating at 1pm. wtf.
[16:29:05] <CaptHindsight> will trade furrywolf
[16:29:28] <CaptHindsight> way up to 21F here
[16:29:35] <furrywolf> I'd guess it's close to 70F. :(
[16:37:21] <HSD> anyone know what the fix was for the USB issue on 2.6.7? I've tried 3 different computers and it won't boot. Keeps complaining about not being able to find/mount root filesystem. Which makes sense because I'm trying to boot from USB stick.
[16:38:02] <HSD> but what is strange is that the release entry claims to have fixed that issue
[16:41:49] <PCW> Hmm unless its been broken recently USB booting works fine (and was only broken on newer Baytrail MBs)
[16:42:26] <PCW> maybe a problem with the image?
[16:45:37] <HSD> md5 checksum matches what is on the website
[16:45:49] <HSD> I tried writing it to the flash drive twice
[16:47:06] <PCW> What CPU? I had trouble with older CPUs
[16:47:17] <HSD> I'm guessing that www.linuxcnc.org/binary.hybrid.iso is 2.6.7
[16:47:22] <HSD> ah, could be.
[16:47:27] <HSD> Core2 Duo
[16:47:35] <HSD> and the other was a Core 2
[16:48:43] <PCW> I dont think they update the ISO for every minor version change so its probably still 2.6.5 or somthing
[16:48:53] <HSD> ah.
[16:48:54] <HSD> ok
[16:48:59] <JT-Shop> HSD, did you "copy" the iso or "burn" the iso?
[16:49:10] <HSD> copy via dd
[16:49:21] <HSD> to usb stick
[16:49:36] <HSD> it loads the kernel and initrd.img
[16:49:39] <JT-Shop> dd?
[16:49:55] <HSD> but when it tries to switch root from ramdisk, it crashes
[16:49:59] <HSD> yeah. dd
[16:50:08] <JT-Shop> what is dd?
[16:50:23] <HSD> raw disk dump
[16:51:31] <cradek> HSD: as far as I know there's no longer a usb related problem
[16:51:36] <JT-Shop> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Hybrid_Iso
[16:51:54] <cradek> I can't explain your results. I've booted it on a large number of random machines.
[16:52:23] <HSD> :S
[16:52:24] <HSD> ok.
[16:52:28] <HSD> I'll try another
[16:52:32] <cradek> maybe your usb stick is bogus
[16:52:42] <HSD> could be. I'll try a different one first.
[16:52:50] <JT-Shop> did you follow the instructions for writing the image to the usb?
[16:52:56] <HSD> PNY attache 4G
[16:53:34] <HSD> Yeah. dd if=binary.hybrid.iso of=/dev/sdd conv=fsync
[16:53:45] <cradek> > Again, be careful, DD is a orbital nuclear laser of power.
[16:53:47] <JT-Shop> ok, just checking
[16:53:49] <cradek> haha who writes these things
[16:53:55] <HSD> hahaha
[16:54:18] <HSD> use dd quite a bit. Got to be careful. :)
[16:55:07] <HSD> let me try another usb stick
[16:55:16] <furrywolf> dd is oooooold. it'd have a different argument structure if written today.
[16:55:18] <HSD> if that doesn't work, another computer. 4th time a charm? :)
[16:55:38] <JT-Shop> did you make the usb port bootable in the computer
[16:56:31] * JT-Shop goes to take the dog out in the blizzard to write her name in the snow
[16:56:51] <furrywolf> hrmm. I don't know what's wrong with my weather station. the logs show it's working, but it's not generating the html files.
[17:01:46] <_methods> unetbootin
[17:03:01] <PCW> I was going to try and clone a SSD with dd but got so confused by the uuid stuff I was never convinced could copy in the right direction
[17:07:10] <_methods> i go into cold sweats every time i type dd
[17:07:35] <furrywolf> grrr. I hope it didn't die. the software doesn't seem to be getting any data, but the display seems to be functioning normally...
[17:07:35] <_methods> just seeing those 2 letters together makes me want to drink heavily lol
[17:11:11] <furrywolf> dd addles laddie's embedded befuddlement, bidding caddish bladders?
[17:11:23] <furrywolf> bah, I'm feeling to useful to think hard enough to actually make that work. :P
[17:11:25] <furrywolf> s/to/too
[17:11:33] * furrywolf goes back to poking at weather station
[17:13:11] <furrywolf> I guess I need to get my 'scope out and check if the serial data looks good... since the display unit thinks its working, and the usb adapter thinks its working, the problem could be the rs232 isolator between the two...
[17:15:51] <furrywolf> the weather station, for reasons known only to some engineer that figured out how to save half a cent, ties one of the serial data lines to chasis ground, floating the whole unit at -15V. this requires optoisolation, as the power supply ground is shared with the actual serial ground...
[17:16:34] <furrywolf> so if you simply plug it all in, it shorts the serial port status line to ground, and doesn't work.
[17:16:35] <JT-Shop> HSD, is the Core 2 Duo a mac book?
[17:17:19] <JT-Shop> nevermind dunno why mac book showed up in the google search
[17:17:42] <HSD> heh.. nope
[17:17:55] <HSD> I even tried it on a newer machine
[17:17:56] <HSD> all failed.
[17:18:05] <HSD> I'm trying out the "use another usb stick" method
[17:18:52] <furrywolf> play around with bios settings... I've had some label the exact same usb thumbdrive as a usb thumbdrive, a usb hard drive, or a usb cdrom...
[17:20:48] <furrywolf> legacy usb support probably needs to be on, too
[17:26:10] * JT-Shop wonders what rpm to drill a 1/4" hole in a 12" carbon gouging rod...
[17:26:51] <furrywolf> any rpm you want?
[17:27:05] <JT-Shop> ok
[17:27:56] <furrywolf> what's the rod diameter? mine are about 1/4", so putting a 1/4" hole in one would be a bad idea...
[17:28:27] <JT-Shop> 5/8"
[17:28:31] <furrywolf> big ones.
[17:29:43] <furrywolf> you'd need, what, a thousand amps to run one of those? heh
[17:33:40] <JT-Shop> heh making a pyrometer
[17:33:53] <JT-Shop> looks like I need to support the rod to drill it
[17:34:20] <furrywolf> run a 5/8 ball-nose endmill through a block of wood
[17:35:19] <JT-Shop> two half blocks?
[17:36:08] <furrywolf> depends on how well you want to support it. lol
[17:36:21] <furrywolf> I was thinking just across the top of a block, making a semicircular groove
[17:36:25] <JT-Shop> I don't want to break another one in half
[17:36:27] <ssi> http://xkcd.com
[17:36:32] <ssi> D:
[17:36:37] <furrywolf> you could also drill a 5/8" hole through a block, then just drill through the wood into the rod
[17:37:49] <JT-Shop> I'm pretty sure I don't have a 12" long 5/8's drill bit but I might be wrong
[17:39:14] <furrywolf> you only need to support where you're drilling, not the whole rod...
[17:39:44] <furrywolf> drill through a piece of 4x4. should be plenty of support for a 1/4" hole.
[17:41:41] <HSD> well I'll be. It was the USB stick. Different one boots just fine
[17:41:47] <HSD> go figure
[17:41:49] <JT-Shop> I don't think a 4x4 will fit in the lathe
[17:43:28] <rob_h> JT-Shop, i always find the dormer calulator pritty spot on for feeds and speeds.. and number of holes said
[17:43:39] <rob_h> http://selector.dormertools.com/web/enu/en-us/inch
[17:43:53] <JT-Shop> thanks rob_h
[17:44:32] <rob_h> you can also play with RPM and feed and change tool life... walter one is much better but not as quick to use
[17:45:05] <JT-Shop> I'm just drilling these on the old manual Samson lathe... I hope

[17:47:40] <JT-Shop> hehe yea
[17:47:47] <rob_h> nice
[17:47:52] <JT-Shop> keeps you warm in the winter
[17:47:54] <rob_h> what doing making castings?
[17:48:07] <JT-Shop> sand and lost pla I hope
[17:48:08] <rob_h> yea like working in a molding shop.. good for winter job.. killer in the summer
[17:48:36] <JT-Shop> this is just for entertainment
[17:48:44] <rob_h> i see
[17:49:01] <JT-Shop> http://gnipsel.com/images/casting/
[17:49:08] <furrywolf> drilling rough holes in wood blocks is what a drill press or a hand drill is for, not a lathe. :P
[17:49:49] <Jymmm> laser works too
[17:50:00] <Jymmm> square holes
[17:50:08] <rob_h> who had to empty that big can ;)
[17:50:23] <JT-Shop> lol, I'm sure I ate the popcorn
[17:50:34] <JT-Shop> a popcorn tin
[17:50:40] <rob_h> aah is that what it is
[17:50:47] <furrywolf> that forum seems to have some very broken css. it's rendering the text quite a bit wider than the boxes it's displayed in, clipped. so you only see the first half of each line.
[17:50:50] <rob_h> a good few movies later then
[17:50:56] <JT-Shop> yea, that would be a huge can of soup lol
[17:51:13] <JT-Shop> yea
[17:51:14] <rob_h> well i do hear you americans like things bigger than the rest of us
[17:52:17] <JT-Shop> probably a present, I'm sure me and the wife would never buy something like that... she gets stuff like that from work
[17:52:50] <JT-Shop> to make it more fun the carbon rod is a bit oversize
[17:53:37] <furrywolf> put it in a piece of pipe, center it, pour molten aluminum around it...
[17:54:04] <furrywolf> melt it off when you're done
[17:58:42] * JT-Shop just needs a 16mm reamer...
[18:00:09] <rob_h> metric
[18:02:18] <SpeedEvil> 11/16ths reamer, and a file?
[18:03:04] <JT-Shop> file a 12" deep hole?
[18:03:35] <JT-Shop> the carbon rod is 0.630" so a 16mm would be perfect... I have a 12mm and a 20mm

[18:05:49] <JT-Shop> hmm, I think I can saw the pvc tube in half and use that
[18:06:23] <SpeedEvil> Why not just ,achine down the rod to 12mm
[18:06:36] <ssi> machining carbon suuuuucks
[18:06:50] <SpeedEvil> JT-Shop: I was meaning file the reamer, it was not very serious
[18:07:08] <ds3> sucks in which way? blackness or abrassiveness?
[18:07:19] <SpeedEvil> I missed what this rod is for
[18:07:31] <ssi> tool-dullingness
[18:07:38] <SpeedEvil> Is there a good reason that you're not using a carbon gouging electrode with the nice existing copper coating?
[18:08:46] <ds3> wonder if it can be machined with a stream of liquid oxygen
[18:08:59] <JT-Shop> SpeedEvil, http://www.alloyavenue.com/vb/showthread.php?10142-Pyrometers%97How-to-Make-Them-and-Use-Them
[18:09:48] <JT-Shop> the PVC pipe reamed to 5/8" and cut in half length wise looks like it will provide enough support with a few hose clamps on it
[18:09:59] <JT-Shop> and less pressure on the bit lol
[18:10:20] * JT-Shop grabs the snow shovel and fights his way to the house... goodnight

[18:53:58] <furrywolf> note to self: glass is HARD.
[18:54:19] <furrywolf> I couldn't find my glass cutter, so tried scoring it with a file... I now have a round-corner file.
[18:55:05] <furrywolf> and a fucking shit edge on my glass, with a couple spiders heading in.
[18:57:20] <SpeedEvil> No diamond rings?
[18:57:36] <furrywolf> no
[18:57:45] <SpeedEvil> Or tile-cutting stuff?
[18:57:51] * furrywolf a) is single, and b) doesn't like jewlery
[18:57:54] <furrywolf> nope
[18:58:07] <furrywolf> anyway, it's done now... it's just a shit job, which I don't like doing.
[18:59:08] <SpeedEvil> If you've got dremel bits, or similar - with diamond coating - drilling a stop-hole is a good plan
[18:59:12] <furrywolf> I'm working on the enclosed porch here, which has 46 (I think that's what I counted) old redwood windows... I replaced three that were broken, but one of them is installed backwards, with the glazing facing in... and over the studs, so I'd have to pull the frame out to reglaze it. since it was just a hole in it, while the others were completely missing panes, I glued a random square of glass over the hole.
[18:59:38] <furrywolf> and the way it's built, it's never coming out... so a patch will do.
[19:00:20] <furrywolf> unfortunately, due to the lack of a glass cutter, while I was trying for a square patch, I got two of the sides nice, but the third, with the file corners the dullest, is wavy, missing a corner, and has a spider.
[19:04:53] <cradek> I've got some scrap glass and a glass cutter here you can borrow - just pop on over to nebraska.
[19:05:18] <_methods> hahahha
[19:05:40] <SpeedEvil> Ah
[19:06:21] <furrywolf> I had scrap glass... I cut it out of one of the broken pieces from one of the other windows.
[19:06:38] <_methods> you don't have scissors
[19:07:05] <furrywolf> ?
[19:07:10] <cradek> do you have a grinding wheel dressing diamond? I've never tried that, but I bet it would work.
[19:07:50] <furrywolf> nope
[19:08:02] <furrywolf> I have lots of things in storage somewhere, but here I don't have much.
[19:08:17] <furrywolf> and "in storage somewhere" usually translates to "go buy another one" if it's less than $20. heh.

[19:09:06] <_methods> cutting glass with scissors
[19:09:45] <furrywolf> does it have to be a video?
[19:10:04] <_methods> i grabbed a video just for you
[19:10:20] <furrywolf> also, I tried with a nice Irwin utility knife blade, and it just mushed the blade without even scratching the glass
[19:11:40] <furrywolf> they make special pliers-like things for cutting stained glass like that
[19:11:54] <furrywolf> it's not good for straight cuts, or real window glass...
[19:13:56] <cradek> it actually worked pretty well
[19:14:15] <cradek> it didn't make any noise while scoring, which made me think nothing was happening, but it left behind a nice scratch
[19:14:51] <_methods> https://www.youtube.com/watch?v=L5u7SCNVYTA
[19:15:00] <_methods> that guy is cutting a regular window just fine
[19:15:10] <_methods> pretty damn straight too
[19:15:33] <_methods> for a meth head
[19:16:01] <MacGalempsy_> Hello :]
[19:16:14] <_methods> i had no idea you could cut glass with scissors
[19:16:20] <furrywolf> that's not a methhead.
[19:16:24] <_methods> that one is getting added to the brain tool box
[19:16:28] <furrywolf> it's more crushing than cutting
[19:16:58] <cradek> underwater I think you can even drill it with a hand drill
[19:17:10] <_methods> cool i had no idea you could do that either
[19:17:22] <_methods> i know the copper pipe and sand trick
[19:17:45] <MacGalempsy_> When the counts of an encoder are unknown, is there a way to count the pulses in LinuxCNC?
[19:17:50] <furrywolf> tweek is a serious problem here, and I've seen plenty of tweekers... neither of them are tweekers.
[19:18:13] <cradek> MacGalempsy_: sure, mark the shaft and turn it 10 or 100 turns and look at the count you get
[19:18:14] <_methods> it was a joke i was making about their appearance
[19:18:27] <furrywolf> and he's not making straight cuts through the middle of a piece, he's making rounded corners.
[19:18:45] <cradek> yeah that wouldn't be quite so possible
[19:18:52] <_methods> ok well i guess you just won't be cutting glass with scissors
[19:19:01] <_methods> have fun not cutting glass lol
[19:20:18] <furrywolf> I don't know what to do about my weather station... bleh! looks like it's going to take a 'scope to figure out what's up.
[19:23:07] <SpeedEvil> furrywolf: what's wrtong with it?
[19:24:31] <furrywolf> a 1pm today, it stopped logging data.
[19:24:46] <furrywolf> the display is showing current, correct data, but nothing is making it to wview.
[19:25:07] <furrywolf> could be the control unit died, could be the pl2303 clone died, could be the rs232 optoisolator died.
[19:27:41] <furrywolf> if the opto died, I might re-engineer it to not need one, by using an isolated dc-dc for the power instead
[19:28:12] <furrywolf> the control unit has one of the most brain-damaged designs I've seen... it ties one of the rs232 status lines to chasis+power ground.
[19:28:26] <furrywolf> and floats the chasis at -10V.
[19:39:23] <furrywolf> 194 day uptime on the box it's on... oh well, I'll try a reboot just to see if it's some weird software thing not reset by replugging the usb adapter.
[19:40:07] <furrywolf> bah, but first, time for work. bbl.
[20:12:45] <Cromaglious> My highest uptime was almost 5 years... But it was kernel 1.3.48 and it had a stack or timer issue.. so max uptime was right around the time mine had to be rebooted...

[20:15:43] <_methods> heheh
[20:15:50] <Cromaglious> $180
[20:16:06] <Cromaglious> I could have bought a QCTP with that
[20:16:13] <Cromaglious> bastards
[20:18:55] <Tom_itx> you should have found one that would do it free
[20:19:12] <Tom_itx> i had one last summer come just for the honey
[20:19:17] <_methods> they should be paying you bees are almost extinct
[20:19:29] <Tom_itx> and gave me a jar of honey to boot
[20:20:08] <_methods> organic honey
[20:20:10] <_methods> lol
[20:20:55] <Tom_itx> i got a pic but can't get this damn phone to sync with the pc
[20:21:10] <_methods> i bought a 24" shars height gage
[20:21:14] <_methods> i hope it's not a turd
[20:25:12] <Cromaglious> .
[20:25:38] <Cromaglious> so for QCTP you guys prefer Wedge or pistol?
[20:26:00] <_methods> wedge
[20:26:35] <Cromaglious> heh $63 and $65 shipping
[20:26:36] <_methods> i want one of those swiss ones
[20:26:56] <Cromaglious> _methods, like abom79 uses? Those are SWEET!
[20:26:58] <_methods> the multifix toolpost
[20:29:13] <Cromaglious> Aliexpress was a 540-000 A) Series similar to what you're looking for $129
[20:29:18] <Cromaglious> A0 series
[20:29:38] <_methods> yeah i'll get one one day
[20:33:50] <Cromaglious> Hmm $135 with shipping Wedge AXA w/ BBH, Knurler, cut off and 2 tool holders
[20:35:13] <Cromaglious> knurler gets the 0.50 more and I can get 5 Tool holders
[20:35:48] <Cromaglious> s/knurler gets//
[20:36:02] <_methods> the good thing about aloris style vs the multifix is tool holders are way cheaper and easier to get in the US
[20:36:24] <Cromaglious> true
[20:36:50] <_methods> you'll want more than just 2 tool holders real quick
[20:37:03] <_methods> if you're as lazy as me lol
[20:37:11] <Cromaglious> hmm dollar more I can get the 'Shars'
[20:46:10] <zee-Lathe> hey
[20:46:19] <zee-Lathe> when a stepper motor spec says 6A/phase
[20:46:21] <zee-Lathe> is that RMS current ?
[20:47:05] <malcom2073> I always assumed it's peak, since most drivers give their ratings in peak anyway... though I'm likely entirely wrong
[20:47:10] <malcom2073> Safest to assume that's peak
[20:47:37] <zee-Lathe> no
[20:47:40] <zee-Lathe> then you lose performance! :{
[20:47:45] <zee-Lathe> if assumption is wrong
[20:47:53] <malcom2073> Crank it up until it gets too hot? :P
[20:49:00] <zee-Lathe> lol
[21:03:59] <dirty_d> you guys think this is a good way to make a propeller hub that needs to be attached to the end of a shaft? http://www.3dvieweronline.com/share/9IJrHOjLlkNmBkq/9IJrHOjLlkNmBkq
[21:04:13] <dirty_d> the idea is to thread mill the smaller inside diameter there
[21:04:23] <dirty_d> and the wider diameter matches the shaft adn is a close fit
[21:12:53] <furrywolf> I have webgl enabled, but that site says I do not.
[21:14:42] <dirty_d> hmm
[21:16:22] <dirty_d> furrywolf, http://i.imgur.com/AinZadv.png
[21:17:12] <furrywolf> looks like a video card thing, with firefox disabling webgl for sites it thinks need hardware rendering, or something like that.
[21:17:54] <furrywolf> do you really want the threads as part of hub, and not a nut pulling a taper tight or such?
[21:19:27] <dirty_d> the top of the hub needs to just have a 4mm stump, so the hole cant go through
[21:20:13] <dirty_d> also this thing will see less than 1Nm of torque
[21:20:38] <furrywolf> oh, I guess we're thinking different kinds of propellers.
[21:22:06] <dirty_d> yea just an RC one
[21:25:14] <Cromaglious> mach3 game pad plugin
[21:25:45] <Cromaglious> erop.. I really need kb/mouse sharing turned on
[21:27:42] <furrywolf> heh, I forced webgl on... frame rate of about 4 seconds per frame, making changing viewpoints next to impossible.
[21:28:15] <furrywolf> apparantly the intel 945 isn't liked for 3d rendering.
[21:32:30] <furrywolf> grrrr. still no logging on my weather station.
[21:34:01] <Simonious> https://sites.fastspring.com/vectric/instant/vcarvepro vs CamBam - I'm going to buy one (lets pretend they are the same price, which would you go with?)
[21:34:43] <furrywolf> dunno, I've used neither.
[21:35:15] <Simonious> what are you generating your gcode with?
[21:35:39] <furrywolf> nothing. I need to get cam software myself. lol
[21:36:00] <furrywolf> $600 seems like a lot of money
[21:39:16] <furrywolf> I guess I'll try a new usb-serial adapter next...
[21:44:21] <Cromaglious> Yeah! Synergy working!
[21:46:04] <Cromaglious> Much Nicer! Virtual Keyboard and mouse... one mouse 3 screens again
[21:47:48] <furrywolf> no idea what synergy is, but I used to have that when I had two desktops...
[21:48:27] <furrywolf> had a program that forwarded the keyboard and mouse from one to the other, so when I went off the side of the screen, they got sent over the network to the other box
[21:49:31] <Cromaglious> http://synergy-project.org/
[21:49:37] <Cromaglious> $10 well worth it
[21:50:13] <Cromaglious> I had it years ago on windows only bosex, now it works windows/linux/mac
[21:50:13] <furrywolf> sounds like it does the same thing the software I used does, but costs money, and has an ugly website. :P
[21:50:52] <furrywolf> x2x irrc
[21:52:22] <Cromaglious> true... But since I paid for it, I get to complain LOADLY
[21:52:28] <Cromaglious> LOUDLY
[21:53:41] <furrywolf> their faq says "Unlike x2x, synergy supports any number of computers and it doesn't require X on Microsoft Windows platforms. It also has more advanced clipboard support and synchronizes screensavers." iirc, x2x supported multiple computers too... and I don't recall any issues with the clipboard or screensavers, although I didn't care if they were synchronized. lol
[21:55:27] <furrywolf> Mar 4 19:35:06 LKG881500 wviewd[2006]: <1425526506598> : storing record for 2015-03-04 19:35
[21:55:28] <furrywolf> yay
[21:55:40] <furrywolf> I replugged the rs232 optoisolator
[21:57:16] <furrywolf> I don't know if it was a loose connection, or if it somehow got itself into a state that needed a power cycling. it's a very simple device, but it does have an onboard chargepump, which could have stopped oscillating somehow...
[21:57:24] <Cromaglious> bbl, gotta put in a USB board into the KB server
[22:06:36] <bobo_> PetefromTn: when the mill is using the tool changer,hopefully before Christmas , how are you planning to measure tool length ?
[22:19:58] <Cromaglious> damn case isn`t tall enough
[22:56:59] <PetefromTn_> bobo_ sorry man was watching TV. I will be measuring tool length the same way I do now until I get a tool probe setup working. Right now I touch off all tools on top of a 123 block in the right rear corner of the table using G59.3 offset and selecting tool length in the drop down.
[22:57:45] <Cromaglious> OK found another USB hub... hopefully it'll work well enough
[22:57:52] <bobo_> no need to be sorry
[23:00:11] <Cromaglious> wish my 10 port USB hub would get here
[23:00:43] <PetefromTn_> altho right now if I don't start finding some paying jobs for this machine I am gonna be selling it off to buy a hot dog cart or something hehe...
[23:01:15] <bobo_> PetefromTn: would this make any sense ? https://www.youtube.com/watch?v=ursqfoi8B30
[23:02:37] <zeeshan> i hate my lathe
[23:02:43] <zeeshan> PetefromTn_: did you ever run negative rake inserts?
[23:02:46] <zeeshan> on the 12x36
[23:03:34] <bobo_> Oh good hot dog stand in the winter
[23:03:38] <zeeshan> lol
[23:03:39] <furrywolf> Cromaglious: usb hubs daisy-chain well
[23:04:25] <furrywolf> where I lived a couple moves ago, I had something like 45 usb devices... lol
[23:04:33] <PetefromTn_> I ran all sorts of tools but most were just hss custom ground ones for specific purposes..
[23:04:46] <zeeshan> hm
[23:04:50] <zeeshan> i get a shitty surface finish
[23:04:58] <zeeshan> with cnmg , vnmg inserts
[23:05:07] <Cromaglious> true on good hubs not te crappy ones I have which are all over 10 years old
[23:05:08] <zeeshan> i was looking at the tool post today
[23:05:23] <zeeshan> i think its flexing under load
[23:06:20] <PetefromTn_> what's wrong with a hot dog stand? I love hot dogs..
[23:07:04] <PetefromTn_> maybe I should make cuban sandwiches like in that movie and become famous?
[23:07:23] <zeeshan> those are delicious! :D
[23:07:58] <PetefromTn_> yeah I know especially if they are made by real cubans!
[23:08:26] <PetefromTn_> This new Hawaii 5-0 series is pretty good! I am enjoying it quite a bit so far...
[23:10:11] <renesis> oh man hot dog stand at school has sierra nevada brewery mustard
[23:10:14] <renesis> i get the stout
[23:11:20] <PetefromTn_> there are some good mustards out there huh.
[23:11:33] <PetefromTn_> I like the ones with horseradish a bit
[23:12:34] <furrywolf> bbl, wolfy bedtime
[23:15:24] <bobo_> renesis was the hot dog stand at school, outside in a snowbank parked next to a snow cone stand ?
[23:17:32] <renesis> no its right off the main quad
[23:17:52] <renesis> also wtf is snow
[23:26:56] <Connor> zeeshan: Get the ball nut figured out ?
[23:28:07] <PetefromTn_> renesis SNOW is the white shit that will be apparently decking our halls around here come tomorrow unfortunately...sigh
[23:30:05] <MacGalempsy> PetefromTn_: we got our share this morning
[23:30:14] <PetefromTn_> Oh lucky you
[23:30:32] <MacGalempsy> yep. been inside all day
[23:30:37] <PetefromTn_> it was a freakin' glorious 65 degrees here today...
[23:30:53] <PetefromTn_> I even had the windows open most of the day
[23:30:59] <Cromaglious> snow == Dihydrogen Monoxide in the Cocaine Forulation -- White and Fluffy -- And it will kill you if you over dose on it.
[23:33:40] <Cromaglious> Or the Crack formulation -- Yellow hard lumps -- which if you shoot it from a gun you can kill with it
[23:35:32] <Cromaglious> The white powder formulation is the smack or Heroin. People go out of their way to get high on it. Peooooooople have been known to die from tripping on it
[23:36:07] <Cromaglious> or lose control and break bones
[23:42:30] <MacGalempsy> I love that scene in Better Off Dead when Booger is on the mountain.
[23:42:58] <bobo_> Cromaglious where you are , how much time ( hours---minutes ) is property owner allowed to have snow on sidewalk ? before being fined
[23:43:10] <MacGalempsy> This mountain is 100% snow! Do you know the street value of this? <take a sniff> I can feel the right side of my brain going numb!
[23:44:00] <MacGalempsy> bobo_: now that sounds like a socialist state if I ever heard of it!
[23:44:47] <PetefromTn_> sounds like bullshit to me heh
[23:44:54] <bobo_> cities need your money
[23:45:29] <MacGalempsy> PetefromTn_: agreed
