Back
[00:01:26] <PetefromTn_> trying to decide which would be better for me the .045 rod or the .045 mig wire spool in ER308L...
[00:01:46] <zeeshan-mill> at the end of the day its user preference
[00:01:53] <zeeshan-mill> the spool is cool cause its continuous
[00:01:54] <PetefromTn_> yup
[00:02:01] <zeeshan-mill> you dont have to stop and grab more filler
[00:02:03] <zeeshan-mill> its a small detail
[00:02:05] <zeeshan-mill> but that annoys me sometimes
[00:02:16] <zeeshan-mill> you also waste less
[00:02:19] <zeeshan-mill> i always have a 3" piece left
[00:02:21] <zeeshan-mill> that i cant use
[00:02:23] <fenn> Wolf_ can you add another bar on the other side to balance out the torque on the headstock?
[00:02:26] <zeeshan-mill> im sure you have that problem too
[00:02:47] <PetefromTn_> so when you are using the roll you don't actually cut off a long piece?
[00:02:57] <Wolf_> yeah, there is a 2nd bar, I didn’t bother to draw it
[00:04:23] <fenn> PetefromTn_: i don't know much about tig welding but i would suggest keeping a photo diary of your welds, with descriptions of what you did and all the relevant parameters in a simple format you can flip through
[00:04:37] <PetefromTn_> not a bad idea
[00:04:53] <Wolf_> write it on the work then pic
[00:05:17] <PetefromTn_> I have been teaching myself to tig weld for a year or two now....it is NOT easy to do this LOL
[00:05:36] <Wolf_> heh, tried alum yet?
[00:05:38] <PetefromTn_> actually it's about 3 years but who's counting
[00:05:57] <PetefromTn_> yeah I do a lot of aluminum practice and have done quite a few jobs for customers
[00:06:14] <PetefromTn_> it's harder I think
[00:06:42] <PetefromTn_> I get a lot of guys with aluminum boats want them fixed LOL
[00:06:44] <Wolf_> alum drives me nuts, too cold one sec, weld puddle falls out the back 3 sec later
[00:06:56] <PetefromTn_> one guy brought me his boat
[00:07:04] <PetefromTn_> it had this HUGE motor on the back
[00:07:13] <PetefromTn_> and it was basically ripping the transom out
[00:07:17] <PetefromTn_> I told him jeez man
[00:07:25] <PetefromTn_> even if I weld it all back together
[00:07:33] <PetefromTn_> it is probably gonna just crack again
[00:07:45] <PetefromTn_> he smiled and said he did not give a crap as long as he can get back out on the lake
[00:07:53] <Wolf_> lol
[00:08:15] <zeeshan-mill> pete nah i just spool it out
[00:08:26] <PetefromTn_> I did a pretty good job welding it I think he was very pleased
[00:08:26] <zeeshan-mill> like it rotates in a tube
[00:08:30] <zeeshan-mill> it keeps coming
[00:08:32] <PetefromTn_> and he has not been back
[00:08:46] <PetefromTn_> so either he sank and drowned
[00:08:54] <PetefromTn_> or it is still working for him LOL
[00:08:57] <zeeshan-mill> my fav is aluminum!!
[00:08:59] <zeeshan-mill> its not picky
[00:09:03] <zeeshan-mill> i hate stainless
[00:09:04] <zeeshan-mill> so picky
[00:09:05] <PetefromTn_> zeeshan ok
[00:09:13] <PetefromTn_> really
[00:09:19] <zeeshan-mill> yea
[00:09:20] <PetefromTn_> how do you setup for aluminum>
[00:09:34] <zeeshan-mill> if its new metal
[00:09:36] <PetefromTn_> I am learning that my setups for stuff is NOT optimal
[00:09:41] <zeeshan-mill> i acetone it
[00:09:47] <zeeshan-mill> dont even bother trying to remove the oxide layer
[00:09:51] <zeeshan-mill> the cleaning action will do that for you
[00:09:56] <zeeshan-mill> if you try to clean it with sand paper
[00:10:01] <Wolf_> guess it depends on how thick, most crap I deal with is truck toolbox so maybe 10ga
[00:10:05] <zeeshan-mill> youll get all these pieces of shit in the weld puddle
[00:10:05] <zeeshan-mill> lol
[00:10:13] <zeeshan-mill> like you know how your weld puddle is shiny
[00:10:18] <zeeshan-mill> youll see this specks floating around
[00:10:23] <PetefromTn_> yup
[00:10:25] <zeeshan-mill> but other than that
[00:10:42] <zeeshan-mill> this is the trick i learned for al:
[00:11:03] <zeeshan-mill> if youre butt welding .125 thick material, usually you set to 125A for steel
[00:11:08] <zeeshan-mill> but for al you wanna be at 160A
[00:11:30] <zeeshan-mill> it takes like 8 seconds to get the puddle going the very first time you weld the material
[00:11:31] <zeeshan-mill> ~
[00:11:41] <zeeshan-mill> but you back your foot up 60%
[00:11:45] <zeeshan-mill> and continue the weld
[00:12:05] <zeeshan-mill> i mean you want 60% throttle when you have established a puddle
[00:12:06] <PetefromTn_> after the puddle forms
[00:12:08] <zeeshan-mill> yea
[00:12:12] <zeeshan-mill> this is what really throws people off
[00:12:17] <zeeshan-mill> they try to weld a 125A
[00:12:25] <zeeshan-mill> and the aluminum just craters
[00:12:37] <zeeshan-mill> .125 thick is forgiving
[00:12:43] <zeeshan-mill> but 0.0625, its game over if you do that
[00:12:55] <zeeshan-mill> which is what most car stuff is :(
[00:13:01] <PetefromTn_> that's the next challenge for me
[00:13:11] <PetefromTn_> they have a LOT of thin walled ally tubing
[00:13:20] <zeeshan-mill> yea man intercooler piping
[00:13:22] <PetefromTn_> I gotta get some setup that works for that next
[00:13:24] <zeeshan-mill> is 0.0625
[00:13:26] <PetefromTn_> exactly
[00:13:43] <zeeshan-mill> also you cant weld it on a steel table
[00:13:57] <zeeshan-mill> you need to grab a stainless or flat aluminum sheet
[00:13:57] <PetefromTn_> scratch it
[00:13:58] <zeeshan-mill> thats clean
[00:14:01] <zeeshan-mill> nahh
[00:14:06] <zeeshan-mill> it leaves this black crap
[00:14:12] <zeeshan-mill> where the conductive path was
[00:14:18] <PetefromTn_> OK
[00:14:20] <zeeshan-mill> its deep stuff
[00:14:41] <Wolf_> makes the back of the weld look like shit if you do sheet backed on steel too
[00:15:10] <zeeshan-mill> what do you mean
[00:15:15] <zeeshan-mill> like inside the tube?
[00:15:16] <PetefromTn_> my welding table is actually MDF believe it or not... I hook the clamp to the parts
[00:15:45] <zeeshan-mill> once you start getting jobs and making money from these guys
[00:15:48] <zeeshan-mill> its worth making a table
[00:15:50] <zeeshan-mill> thats got 1/2" plate
[00:15:51] <Wolf_> like a butt weld on alum sheets but backed up with steel plate
[00:15:57] <zeeshan-mill> Wolf_, yea!
[00:16:01] <zeeshan-mill> it ruins the sheet
[00:16:38] <PetefromTn_> I actually like the MDF...it's easier on parts I think but it does burn if you get it too hot
[00:16:40] <zeeshan-mill> my problem is i learned from aluminum
[00:16:41] <Wolf_> top side looks ok tho, I have done it a few times to fill holes in things
[00:16:44] <zeeshan-mill> so i have a harder time keeping a puddle in stainless
[00:17:30] <PetefromTn_> they have a scrap bucket over there with a BUNCH of ally tubing I am gonna grab some and play with it
[00:17:51] <Wolf_> when I went to school for welding I qualified in steel, but I was planning on doing roll cages and off road truck stuff
[00:18:21] <deep_pink> this was looong day
[00:18:27] <Wolf_> in tig that is
[00:18:33] <PetefromTn_> I have done some of that for my own trucks... I built several different Rock Crawler Suzuki samurai's etc...
[00:18:58] <Wolf_> most days now I just run the metal glue gun
[00:19:01] <PetefromTn_> roll cage, custom bumpers, nerfs etc.
[00:19:23] <deep_pink> Wolf_: " metal glue gun"???
[00:19:28] <PetefromTn_> MIG
[00:19:30] <Wolf_> mig
[00:19:34] <deep_pink> LOL
[00:20:23] <PetefromTn_> I have a cheapo mig welder but ever since I got the Tig it just collects dust.. I should sell it and get a nicer one but I doubt I would use it that much
[00:20:43] <Wolf_> when I have actual work flowing in the shop, I’ll run a 30lb spool out in a month
[00:20:50] <PetefromTn_> damn
[00:20:55] <PetefromTn_> thats a lot of welding
[00:21:33] <PetefromTn_> I get jobs from my local ad but most of it is boats, bumpers,trailers etc. etc. Nothing crazy and mostly done in a couple hours
[00:21:51] <Wolf_> 16’L x 8’W x 5’T dumpster take some welding
[00:22:19] <PetefromTn_> I worked in a local CNC job shop and they had a fab shop attached
[00:22:35] <PetefromTn_> they were making these REALLY BIG dump buckets for some kinda earth mover machine
[00:22:53] <PetefromTn_> they spent hours and hours on each one with a large MIG
[00:23:10] <PetefromTn_> damn thing was crazy heavy when it was finished
[00:23:23] <PetefromTn_> that is some hard work I think.
[00:23:54] <PetefromTn_> gotta climb inside and all around it to get to the weld points etc.
[00:24:31] <Wolf_> this is why I want a cnc plasma table
http://i1139.photobucket.com/albums/n541/wolfmetalfab/f550%20Stuff/5B923E6E-DADC-421F-B84A-C1110DEC0036-5985-000004D8F0085D6C.jpg
[00:25:00] <PetefromTn_> for the holes?
[00:25:16] <Wolf_> yeah and doing the hitch plates
[00:25:30] <PetefromTn_> is that a rolllback?
[00:25:37] <Wolf_> hook truck
[00:25:41] <PetefromTn_> OK
[00:25:53] <Wolf_> thats my personal truck
[00:26:03] <PetefromTn_> well I used up the last bit of that wire I got so I gotta get some ordered or practice is over LOL
[00:26:10] <PetefromTn_> oh okay
[00:26:17] <PetefromTn_> nice
[00:26:17] <Wolf_> http://i.imgur.com/yERX7l3.jpg :D
[00:26:27] <Wolf_> makes yard work easy
[00:26:41] <PetefromTn_> 450?
[00:27:11] <Wolf_> 550 w/ payload plus, 19.5k gvw
[00:27:24] <PetefromTn_> nice
[00:27:56] <PetefromTn_> well I gotta hit the sack. got a bunch of machining to do tomorrow... nice chatting Tig stuff with you guys...
[00:30:49] <zeeshan-mill> pete
[00:30:53] <zeeshan-mill> damn he left
[00:35:09] <Wolf_> ouch, $165 for the shaft couplers for the x/y/z
[00:37:57] <fenn> hose clamps and thick rubber tube :P
[00:38:15] <Wolf_> lol maybe…
[00:38:32] <fenn> you could make an oldham coupling with the mill
[00:43:30] <Wolf_> true, oldhams are little less spendy too
[00:43:51] <Wolf_> $27 per axis
[00:45:47] <deep_pink> Wolf_: get some ruland couplers
[00:45:48] <Wolf_> vs $54 per
[00:49:10] <Wolf_> which one? like saying I should get a home depot
[00:58:04] <deep_pink> Wolf_: what do you want to buy from home depot?
[00:58:11] <deep_pink> cupling?
[00:58:33] <Wolf_> which ruled… they make them all
[00:58:42] <Wolf_> Ruland*
[00:59:37] <fenn> they are known for their helical beam couplers
[00:59:47] <fenn> but they do make a lot of different kinds of couplers
[01:01:07] <deep_pink> Wolf_:
http://www.ruland.com/
[01:01:21] <deep_pink> Wolf_: I have
http://www.ruland.com/ps_couplings_jaw.asp#about
[01:04:10] <Wolf_> whats the suggested torque rating for a mill?
[01:04:17] <Wolf_> on the spider
[01:11:14] <deep_pink> I have the 1.3" red spider
[01:11:37] <Wolf_> that 9.9Nm
[01:12:05] <deep_pink> correct.
[01:12:38] <fenn> how big are the handles on an x-1
[01:12:50] <Wolf_> so on my smaller machine, which most people run with 270oz in
[01:13:18] <deep_pink> you measure the torque?
[01:13:35] <Wolf_> maybe 75mm
[01:14:06] <Wolf_> no I didn’t measure the torque cause I need to clean and redo my gibs
[01:14:43] <deep_pink> how you do your gibs?
[01:15:06] <fenn> 270oz*in is like setting a full milk jug on the handle
[01:15:13] <Wolf_> take out the steel one and throw them away and make brass ones
[01:16:48] <deep_pink> I thing that the gib on my Z axis have to much space
[01:16:49] <fenn> might as well scrape the ways while you're at it
[01:17:08] <fenn> super precision x-1
[01:18:04] <Wolf_> well, I was planning on doing the long travel kit soon, that adds new base plate and carriage
[01:19:00] <fenn> madness
[01:19:08] <fenn> there's a perfectly good van norman sitting there
[01:19:31] <Wolf_> lol, listing didn’t even have pics
[01:20:30] <fenn> BREAKING NEWS old machinist doesn't know how to use new electronic gadgets
[01:21:07] <renesis> sounds like a pro
[01:21:37] <fenn> you should at least go look at it
[01:21:43] <Wolf_> vertical/ horizontal ram by Van Norman non-op currently, needs some reassembly no tooling << listing didn’t inspire much hope either
[01:23:04] <fenn> it's basically free
[01:23:14] <fenn> $500 is less than scrap value
[01:23:31] <Wolf_> http://washingtondc.craigslist.org/nva/tls/5171562665.html $500 more
[01:23:57] <fenn> so you're spoiled for choice
[01:24:07] <fenn> save me the van norman then :P
[01:24:41] <Wolf_> that Wells is tempting :D
[01:24:46] <deep_pink> someone know about sliting saw?
[01:25:00] <Wolf_> I know they spin
[01:25:17] <deep_pink> I want to make a compass from scratch,
[01:25:44] <Wolf_> eh, like the markings?
[01:27:22] <Wolf_> wow MariTools is quick on the shipping
[01:27:46] <deep_pink> I need to mak very thin slot - about 0.2 mm
[01:28:19] <deep_pink> make*
[01:28:25] <archivist> cut
[01:29:28] <deep_pink> ok - cut
[01:29:32] <deep_pink> but what
[01:30:06] <deep_pink> but where I can get sliting saw for that?
[01:31:09] <archivist> just google and find your local supplier
[01:32:03] <archivist> my local supplier is
https://www.cromwell.co.uk/shop/39260104/small-diameter-slitting-saws
[01:32:47] <deep_pink> how I'm connect it to the r8?
[01:32:56] <Wolf_> saw arbor
[01:33:25] <deep_pink> http://www.shars.com/slotting-saw-arbor-r8-shank
[01:34:39] <Wolf_> so back to the coupler thing, so I should be ok with the 19mm w/ 15lb-in/1.7Nm nominal torque tight?
[01:38:11] <fenn> nominally
[01:39:01] <deep_pink> use 2 times more, than what you think.
[01:39:09] <fenn> i'd be more worried about backlash in couplers than torque ratings
[01:39:53] <fenn> also things that flex have lower fatigue life if operated near their limits
[01:40:54] <Wolf_> well, in theory… my motors will max out at 3Nm
[01:41:08] <Wolf_> 425oz in
[01:41:41] <zeeshan|2> youre going to stall your spindle
[01:41:43] <zeeshan|2> before you stall those!
[01:42:14] <fenn> you mean snap it off
[01:42:17] <zeeshan|2> hehe
[01:42:21] <zeeshan|2> can someone tell me whats going here
[01:42:21] <zeeshan|2> https://www.youtube.com/watch?v=Txk2r3_rBHM
[01:42:25] <Wolf_> stall the spindle? doubt it, won’t stall with half a bit
[01:42:27] <zeeshan|2> i got dc injection braking working
[01:42:34] <zeeshan|2> but when i try to reverse the spindle
[01:42:36] <zeeshan|2> it doesnt activate
[01:43:51] <fenn> is your current setup just the VFD? or is linuxcnc involved somehow?
[01:44:05] <zeeshan|2> just the vfd
[01:44:14] <zeeshan|2> like if i stop it from ccw or cw
[01:44:17] <zeeshan|2> it stops instantly
[01:44:27] <zeeshan|2> but when i try to reverse the spindle while it's running
[01:44:28] <zeeshan|2> it wont
[01:44:48] <zeeshan|2> i think my vfd needs to see 0 rpm commanded for a brief moment or something
[01:45:05] <fenn> that would make sense
[01:45:29] <fenn> are you using some sort of e-stop mechanism to brake the spindle?
[01:45:51] <fenn> like is not starting back up a safety feature?
[01:46:23] <zeeshan|2> its some builtin feature in the vfd
[01:46:39] <zeeshan|2> how it detects when to brake i don't know
[01:46:43] <zeeshan|2> the manual is crap
[01:48:21] <archivist> command a faster deceleration
[01:48:45] <zeeshan|2> hm
[01:49:04] <zeeshan|2> im confused how i can command afaster decel than what it currently is
[01:49:07] <zeeshan|2> from 500 rpm to 0
[01:49:15] <zeeshan|2> it goes there in like .5 sec?
[01:49:24] <Wolf_> ok, so if I go with Ruland couplers i’m looking at $93…
[01:49:31] <zeeshan|2> so decel time is set isn't it?
[01:49:44] <fenn> but maybe it doesn't know that it decelerated so fast and is waiting for something to happen that already happened
[01:50:24] <zeeshan|2> i have the option to dc inject using mesa7i77
[01:50:29] <Wolf_> I think the Oldham win...
[01:50:30] <zeeshan|2> using the motion.spindle-brake option
[01:50:32] <zeeshan|2> but the problem is
[01:50:36] <zeeshan|2> it's always on!!
[01:50:42] <zeeshan|2> in the beginning
[01:50:44] <zeeshan|2> that'll fry the motor
[01:51:33] <SEL> hello good morning
[01:53:10] <SEL> i say true type tracer is really good for testing motors :-)

[08:27:47] <archivist> sudo make me a cnc
[08:38:41] <alex_jon1> Sorry, try again.
[08:38:49] <alex_jon1> archivist: sudo: 1 incorrect password attempt
[08:42:10] <Simonious> dang.. HMSXpress doesn't do 3d toolpaths, HMSWorks does, guess which one is free..
[08:42:41] <Simonious> anyone happen to know what HMSWorks costs?
[08:42:59] <archivist> more than your pocket money
[08:43:22] <Simonious> more than my boss's pocket money? :P
[08:43:55] <Simonious> CAMBAM *can* do it, but it's pretty terrible at anything 3D IMO
[08:44:06] <Simonious> just because it's so painful to use
[08:48:15] <Simonious> Hmm, maybe SketchUCam is good.. could export an STL from SolidWorks..
[08:48:35] <archivist> when I asked at a show I got responses between 18000 and 60000 pounds for cam for 5 a axis machine
[08:49:06] <Simonious> well sure, but that's 5 axis.. I'm thinking 3 axis
[09:05:53] <Hawku> Simonious: maybe you could try the Fusion 360 CAM?
[09:06:19] <Hawku> it is using HSM kernel
[09:06:55] <Simonious> Hawku: it's on my list, is it 3D capable? I'm finding most of the free options are 2.5 - CAMBAM can sortof do 3D, but if I can help it I'll only use it for 2.5D
[09:08:29] <Hawku> Simonious: i think that the basic version is 2.5, but if you are a hobbyist/student/startup you get a free Ultimate version for a year
[09:10:10] <Hawku> after a year you can renew your free license
[09:14:00] <Hawku> Simonious:
http://knowledge.autodesk.com/support/fusion-360/troubleshooting/caas/sfdcarticles/sfdcarticles/Fusion-360-Packaging-FAQ.html
[09:17:01] <Hawku> "The functionality previously available in Fusion 360 Ultimate (animations and 3-axis machining) will now be available in Fusion 360 at $300 with an annual subscription"
[09:18:02] <Hawku> so the basic $300/year edition does have a 3-axis CAM
[10:02:09] <PetefromTn_> fusion 360 ultimate is 100 a month and includes 3+2 axis cam and simulation.. honestly that is not really that bad. fusion 360 is actually free for hobbyists/students/and startups..
[10:03:15] * Jymmm subscribes on PetefromTn_'s credit card.. THANKS!
[10:03:38] <PetefromTn_> heh was not aware I HAD a credit card
[10:04:28] <Jymmm> PetefromTn_: Oh, you have 4 plus 3 morgages, and 2 $20K lines of creidt that are almost maxed out this month.
[10:04:53] <PetefromTn_> damn..
[10:05:05] <PetefromTn_> no wonder I have no freakin' money LOL
[10:05:54] <Jymmm> Oh you do, but it's stuck in drug and humand traffiicing for the next 18 months or so
[10:06:24] <PetefromTn_> woah I am a BAAADD Boy
[10:07:07] <Jymmm> Well, not really, unless you goto florida... you have 3 felony warrants
[10:07:30] <PetefromTn_> jeez and I wanted to go to florida
[10:07:46] <Jymmm> Free room and board when/if you do =)
[10:08:04] <PetefromTn_> just don't drop the soap right ;)
[10:08:37] <Jymmm> something like that, else that's your thing of course, who am I to judge.
[10:08:46] <Jymmm> unless*
[10:09:06] <PetefromTn_> Don't ask Don't tell hehe
[10:09:23] <Jymmm> Eh, LET YOUR FREAK FLAG FLY BABY!!!
[10:10:13] <Jymmm> Well left-rear brakes done; I hope the caliper was the cause of all that mess.
[10:10:13] <PetefromTn_> hoping to get my Tee fitting so I can put this new Flow regulator on my tig setup today and try it...
[10:10:33] <PetefromTn_> that'd be good
[10:10:35] <Jymmm> mail order plumbing parts?
[10:10:49] <PetefromTn_> mail order Tig welder parts anyway
[10:11:12] <Jymmm> whats so special that you can't just grab brass ones from the big orange borg?
[10:11:34] <PetefromTn_> I have some hose I can use here for the gas line but I need to get a hose barb fitting for the end I think I may have one in my junk box tho..
[10:11:55] <PetefromTn_> well it has a special fitting that mates to the tank valve
[10:12:04] <Jymmm> special?
[10:12:06] <PetefromTn_> and two females of that same fitting on each end
[10:12:15] <PetefromTn_> different anyway
[10:12:24] <PetefromTn_> who knows they might have them at Home Despot
[10:12:41] <PetefromTn_> but they are cheap online really and I don't have to go anywhere ;)
[10:12:43] <Jymmm> Plumbing fittings are the worse, there are SI many different types of threads it's sad
[10:12:54] <Jymmm> gotcha
[10:12:59] <Jymmm> SO*
[10:13:22] <Jymmm> then add propane/gas to that.... EEEEEESH!
[10:14:07] <PetefromTn_> http://www.ebay.com/itm/Argon-Gas-Bottle-Y-adapter-connect-2-regulators-to-1-bottle-Western-T-92-C-2580-/191547352277?hash=item2c991ca4d5
[10:14:19] <PetefromTn_> that is the one I bought
[10:15:23] <Jymmm> I had to go from faucet thread to make garden fitting, then from female garden to male pipe fitting just to attache a shower hose to a tub faucet, AND the faucey to garden is one that had and orange borg doens't even stock anymore even though I bought it from them years ago
[10:15:43] <PetefromTn_> like I said it is kinda different from the typical brass fitting stuff maybe you can get it local I dunno
[10:15:46] <Jymmm> Oh, a POL fitting
[10:16:15] <PetefromTn_> ?
[10:16:41] <Jymmm> thats a typical propane fitting
[10:16:52] <Jymmm> http://www.propanewarehouse.com/product-category/fittings/pol-fittings/
[10:17:06] <Jymmm> or CGA580 too I think
[10:17:18] <Jymmm> as there is no o-ring
[10:18:03] <Jymmm> PetefromTn_:
http://www.propanewarehouse.com/shop/accessories/propane-pol/
[10:18:17] <Jymmm> for future reference
[10:19:50] <PetefromTn_> ok
[10:19:58] <Jymmm> althugh propane aint inert, it goes boom =)
[10:19:59] <PetefromTn_> same price really
[10:20:11] <Jymmm> yeah, I mena if you are in a pinch is all
[10:20:40] <Jymmm> I always like having a CYA backup =)
[10:20:59] <PetefromTn_> always
[10:21:29] <Jymmm> skunky!!!
[10:22:05] <PetefromTn_> where are you located jymm?
[10:22:12] <Jymmm> or, indian name is: Stinky one who sprays dogs!
[10:22:18] <Jymmm> PetefromTn_: Calif
[10:22:23] <PetefromTn_> ok
[10:23:37] <_methods> ahhh that's what's wrong with him
[10:23:53] <_methods> lol
[10:24:34] <Jymmm> What, not living in a blizzard all winter long?
[10:25:25] <Jymmm> Although, that might have changed, we'll see.
[10:25:39] <_methods> global warming
[10:26:30] <Jymmm> But... worse case, I have 2.5 cords of seasoned and split wood out back
[10:37:49] <Wolf_> That propane POL won’t fit a inert gas bottle
[11:11:27] <archivist> the different gas threads are to stop you re inventing the big bang theory
[11:12:48] <PetefromTn_> aww where's the fun in that?
[11:38:47] <Jymmm> Heh, they are using propane now to exterminate gophers. They pump propane into the holes/tunnels and it's the percussion that kills them. It's so frickin loud that they have to call the fire/police before igniting.
[11:39:36] <pcw_home> propane and oxygen
[11:40:15] <Wolf_> I just use a rifle
[11:40:35] <Jymmm> I only heard propane myself. Although oxy-propane torches are nice
[11:41:01] <Jymmm> Wolf_: How tdo you get it around all the bends/corners?
[11:41:24] <Wolf_> I don’t have gophers, I have woodchucks here
[11:41:29] <PetefromTn_> I much prefer a precision Air Rifle with High power scope out to about 75 yards LOL
[11:42:01] <Wolf_> I use a .17 HMR, last one I shot was at 120yrs out
[11:42:05] <PetefromTn_> Silent and deadly
[11:42:51] <PetefromTn_> beyond 75 yards I have more powerful hunting style airguns that will take care of things
[11:43:15] <Wolf_> mine is loud as fuck but IDGAF :D
[11:43:32] <PetefromTn_> yeah man .17 HMR IS indeed LAF
[11:43:41] <Jymmm> Got BEAR(s) ???
http://www.thedenverchannel.com/news/trending/bear-pokes-its-head-through-cat-door
[11:44:13] <Wolf_> nice, steppers will be here Fri :)
[11:44:17] <PetefromTn_> the precision target PCP rifles basically are silent for all intents and purposes. It is not unusual to shoot one critter and then shoot his buddy sitting right next to him LOL
[11:44:51] <PetefromTn_> it's almost unfair really so I don't much do it anymore unless it is really a pest
[11:45:22] <Wolf_> new vid card for my cnc computer tomorrow, along with some new end mills. Just need my mcmaster order to ship now
[11:48:50] <Wolf_> so trying to get by with the wrong stuff for the task at hand, cut up some copper M pipe to use as soft jaws in the 4 jaw to chuck the ball screw up, that should work right?
[11:50:40] <Jymmm> I have no clue, but I'd hope that your ballscrew is harder than anything you put it in.
[11:51:13] <Wolf_> well, still don’t want to damage it in any way
[11:51:27] <Jymmm> need to turn it's ends?
[11:52:10] <PetefromTn_> I machined a brass adapter in the three jaw to clamp onto my ballscrews for the RF45... worked pretty good
[11:52:19] <Wolf_> yeah, eBay score that I have had for a while, only has a 26mm long 10mm shaft on it right now, plus I need to cut it down
[11:52:47] <Jymmm> cool
[11:53:00] <PetefromTn_> used carbide insert tooling to break thru the hardness layer.. then it machined normally
[11:53:13] <Wolf_> on a 14mm dia, 5mm pitch thk screw
[11:53:19] <PetefromTn_> I also used an angle grinder to cut thru the hardest part on the outside
[11:54:21] <Wolf_> thats what I was thinking of doing, chuck it, center it, cover everything, use a paper plate to shield the chuck, 4.5 grinder w/ the lathe spinning
[11:55:09] <Rab> https://www.youtube.com/watch?v=fNuI6keQXYA
[11:55:10] <PetefromTn_> yup that is basically what I did but I used plastic sheeting on everything taped down
[11:55:39] <Wolf_> yeah, I have a roll of tape and drape, good idea :)
[11:56:29] <PetefromTn_> Rab wouldn't want to get sucked up into that monster huh
[11:57:30] <Rab> PetefromTn_, nope. Wish they mentioned where it's used.
[11:58:01] <Rab> Ingenious design, though. Beats a rotating clutch.
[11:58:55] <PetefromTn_> that overall picture kinda reminds me of an old elevator shaft lift motor in a big building but it is MUCH larger than that I think. also a helluva lot faster apparently LOL
[12:04:45] <Wolf_> quality…
http://i.imgur.com/kEDpfS8.jpg the X axis lead screw block off my x1…
[12:05:43] <Tom_itx> no thrust bearings on it?
[12:05:51] <Wolf_> not yet
[12:06:35] <Wolf_> have some on order tho, should help things
[12:07:46] <zeeshan|2> Sync_: i was monitoring the temperature of the motor
[12:07:50] <zeeshan|2> it really didnt warm ujp
[12:08:04] <zeeshan|2> im only injecting 50% "braking power" as the manual puts it
[12:08:07] <zeeshan|2> for 0.4 seconds
[12:08:34] <zeeshan|2> can someone please help me fix rigid tapping with the brake!! :P
[12:08:41] <zeeshan|2> i don't know why it's acting the way it is
[12:09:06] <zeeshan|2> https://www.youtube.com/watch?v=Txk2r3_rBHM
[12:09:13] <zeeshan|2> video shows normal stopping from 500 rpm to 0
[12:09:20] <zeeshan|2> and then 250 rpm to -250 rpm
[12:09:31] <Wolf_> one of my plans for my sad little x1 conversion is to get
http://littlemachineshop.com/products/product_view.php?ProductID=2297 and ball screw it, and if possible rear mount the stepper
[12:13:36] <zeeshan|2> pcw_home: any clues? :D
[12:14:53] <pcw_home> I think you are better off adding a braking resistor and setting you accel times faster on your VFD
[12:15:04] <zeeshan|2> what is wrong with dc injection
[12:16:20] <pcw_home> rather uncontrolled decell and accel would still need to be set in the VFD
[12:16:38] <zeeshan|2> pcw_home: im confused why it doesn't suddenly brake
[12:16:42] <zeeshan|2> before reversing
[12:16:47] <zeeshan|2> but if i go from reverse to stop
[12:16:49] <zeeshan|2> or forward to stop
[12:16:50] <zeeshan|2> it brakes
[12:17:37] <pcw_home> it may be that the drive disallows braking if commanded speed is not 0
[12:17:55] <Sync_> zeeshan|2: is some sort of accel limit in the VFD?
[12:18:04] <zeeshan|2> sync i dont wanna touch accel limit
[12:18:07] <zeeshan|2> because like pcw is saying
[12:18:10] <zeeshan|2> i need a resistor for that
[12:18:13] <pcw_home> so with a complicated hal config it might be usable
[12:18:21] <zeeshan|2> cause if i decrease my decel time any lower, it overcurrents the vfd
[12:18:30] <Tom_itx> go get a stove element and make a brake resistor
[12:18:30] <pcw_home> I would get the resistor
[12:18:37] <Sync_> well then get a bigger vfd or a braking resistor
[12:18:38] <zeeshan|2> why though guys
[12:18:46] <zeeshan|2> what makes a resistor superior to dc injection
[12:18:54] <zeeshan|2> both do the same thing at the end of the day right?
[12:18:59] <Tom_itx> it keeps you warm in the winter
[12:19:20] <pcw_home> because it a better solution since Z needs to track
[12:19:21] <Tom_itx> and it's probably not as hard on the driver
[12:19:55] <Sync_> zeeshan|2: you get a controlled ramp
[12:19:56] <pcw_home> better to have controlled accel ramps
[12:20:01] <pcw_home> ha
[12:20:01] <Sync_> instead of whatever is happening inside the motor
[12:20:31] <zeeshan|2> would another benefit be
[12:20:33] <zeeshan|2> less heating of the motor?
[12:20:46] <zeeshan|2> cause you're not applying dc now
[12:20:47] <pcw_home> and the brake resistor/ faster accel helps everywhere
[12:21:00] <Sync_> well, the heat will be about the same
[12:21:04] <Tom_itx> zeeshan|2, i'm not sure that would matter
[12:21:10] <Sync_> the only problem is when you are using the DC brake to hold a load
[12:21:13] <Tom_itx> the motor is still acting like a generator
[12:21:16] <Sync_> because you need external cooling
[12:22:44] <zeeshan|2> im not holding a load with it sync
[12:22:50] <zeeshan|2> im injecting it for .4 sec
[12:22:52] <zeeshan|2> below 20hz only
[12:22:58] <zeeshan|2> which is where i really need it
[12:23:27] <zeeshan|2> Tom_itx: but that extra power is being dumped into a resistor
[12:23:30] <pcw_home> i suspect the drive prevents that
[12:23:42] <zeeshan|2> yea it goes
[12:23:44] <Tom_itx> zeeshan|2, where is that power coming from?
[12:23:45] <zeeshan|2> "overcurrent"
[12:23:50] <zeeshan|2> if i increase it to 2seconds
[12:23:55] <pcw_home> over voltage
[12:24:19] <pcw_home> oh for DC could be overcurrent
[12:24:55] <pcw_home> you will get overvoltage if you deccel too fast without a brake resistor
[12:25:08] <zeeshan|2> my goal isn't to decrease speeds throughout the power band
[12:25:08] <zeeshan|2> i really want it only for reversal for tapping
[12:25:08] <zeeshan|2> thats where i only need it
[12:25:08] <zeeshan|2> Tom_itx: i dunno much about the subject, but im thinking a static field vs rotating field
[12:25:09] <zeeshan|2> maybe more heating with the static? :P
[12:26:05] <zeeshan|2> youre right
[12:26:12] <zeeshan|2> if decel is set too little
[12:26:14] <zeeshan|2> it'll overvoltage
[12:26:29] <Tom_itx> seems you've been there
[12:26:41] <zeeshan|2> to me i want to do less work and less drilling
[12:26:50] <zeeshan|2> if dc injection vs resistor braking
[12:26:58] <zeeshan|2> is the same thing in terms of rigid tapping
[12:27:02] <zeeshan|2> than i really wanna implement dc injection
[12:27:08] <zeeshan|2> cause it's already done physically for me :P
[12:27:23] <pcw_home> the ac drive is probably more efficient at lower speeds (more rotor flux) so better for reversals
[12:27:55] <zeeshan|2> its a 10hp 3phaser drive
[12:28:01] <zeeshan|2> running a 5hp 3phase motor
[12:28:04] <zeeshan|2> running off single phase :P
[12:28:17] <zeeshan|2> i have experimented with like .5 decel time at lower speeds < 20hz
[12:28:24] <zeeshan|2> and it stops instantly without overvoltage
[12:28:30] <zeeshan|2> but anything above that, .5 is too little
[12:28:35] <zeeshan|2> i have it set to 3 s
[12:28:57] <zeeshan|2> the one thing i can see being benefitting -- correct me if im wrong
[12:29:00] <pcw_home> and I expect you can get faster reversals with a brake resistor than DC injection
[12:29:01] <zeeshan|2> but dc injection is a violent stop
[12:29:02] <pcw_home> when you factor in the ability of Z to track
[12:29:13] <zeeshan|2> while dc braking is a smoother soft
[12:29:16] <zeeshan|2> controlled stop
[12:29:20] <zeeshan|2> based on my decel rate
[12:37:09] <zeeshan|2> im looking at the vfd spec sheet
[12:37:25] <zeeshan|2> for 100% braking torque it recommends:
[12:38:02] <zeeshan|2> 10 ohm 750W, 2 of them in series and says "Braking time 7sec max, operatation rate: 4% ED max"
[12:38:10] <zeeshan|2> it doesn't definite ED :P
[12:38:14] <zeeshan|2> define
[12:38:36] <zeeshan|2> im assuming that duty cycle
[12:39:11] <zeeshan|2> what do you guys think
[12:39:17] <zeeshan|2> 2 10 ohm resistors @ 750w in series
[12:41:42] <zeeshan|2> this mount sound silly
[12:41:48] <zeeshan|2> can i just take a space heater
[12:41:50] <zeeshan|2> and hook it up directly
[12:41:57] <zeeshan|2> (by passing the switch etc)
[12:46:14] <zeeshan|2> this is a 1500W space heater
[12:46:19] <zeeshan|2> measuring the settings at full max
[12:46:26] <zeeshan|2> im getting 20~ ohms
[12:46:45] <zeeshan|2> PERFECT :D
[12:49:33] <zeeshan|2> wake up people!!
[12:50:42] <pcw_home> stove element as Tom_itx suggested
[12:50:51] <zeeshan|2> i dont know where to get one
[12:51:03] <zeeshan|2> what is wrong with using this space heater??!
[12:51:18] <zeeshan|2> im not sure what the element is rated for voltage wise
[12:51:23] <zeeshan|2> but the cord on this thing says 300V 105C
[12:51:30] <zeeshan|2> http://www.canadiantire.ca/en/pdp/likewise-ceramic-heater-0435877p.html#.VdNrNvlVhBc
[12:51:33] <zeeshan|2> this is what im talking about
[12:51:40] <pcw_home> just bulky (and you dont want the thermostat opening)
[12:51:48] <zeeshan|2> no ill by pass that
[12:51:54] <zeeshan|2> ill literally have the wires going to the elemnent
[12:52:01] <zeeshan|2> skipping the fan and thermostat
[12:52:03] <zeeshan|2> and switch
[12:52:20] <zeeshan|2> for stove elements ill need to build an enclosure
[12:52:34] <zeeshan|2> and try to somehow thermally isolate them from the enclosrue
[12:53:28] <zeeshan|2> http://www.homedepot.ca/product/element-small-6-spade/969960
[12:53:32] <zeeshan|2> you're talking something like this right?
[13:43:01] <alex80> hi - is there someone online who can help me with a tool-change/tool probe problem ?
[13:43:34] <archivist> ask the real question then one might be able to help
[13:43:49] <alex80> okay :)
[13:44:23] <archivist> I use a mandraulic toolchange
[13:46:59] <alex80> i want to put in the first tool by hand, touch of to the surface, set that to z=0. linuxcnc schould measure that tool to a fixed contact. the following tool changes by hand too, but linuxcnc schould measure the tools, and set the correct offset. is that possible and how can i integrate that ?
[13:47:51] <alex80> found al lot of examples but all of them have a incomplete documentation
[13:48:05] <alex80> or the scripts etc didnt work
[13:48:44] <alex80> today i have tried that
http://www.linuxcnc.org/index.php/english/forum/10-advanced-configuration/5596-manual-tool-change--tool-lengh-touch-off?limit=6&start=36
[13:49:12] <alex80> (script in the yellow box tool-change.ngc)
[13:49:37] <alex80> by the first M6 command the machine move the z axis a bit then stopped - nothing.
[14:00:07] <archivist> noisy switch, code does not match your machine, some other fault
[14:01:13] <zeeshan|2> alex
[14:01:16] <zeeshan|2> you could use a tool setter
[14:01:50] <zeeshan|2> oh you got the hardware already
[14:02:02] <PetefromTn_> the question is what kind of machine is it and is the toolholders repeatable
[14:02:10] <PetefromTn_> are
[14:02:26] <zeeshan|2> PetefromTn_:
[14:02:30] <zeeshan|2> can you take a pic of yuor stove element setup?
[14:02:52] <PetefromTn_> you mean the one I cook hotdogs with ;)
[14:03:13] <zeeshan|2> no for your vfd
[14:03:13] <zeeshan|2> haha
[14:03:18] <zeeshan|2> im trying to figure what to do
[14:03:25] <zeeshan|2> that i can possibly get implemented today
[14:03:27] <zeeshan|2> i got a week off
[14:03:30] <zeeshan|2> from uni
[14:03:33] <PetefromTn_> I can but I gotta go pickup my kids right now
[14:03:34] <zeeshan|2> wanna make the most of it
[14:03:37] <zeeshan|2> ok np!
[14:04:16] <alex80> kind of machine: recycled stuff / self construced, the toolholder is not repeatable.
[14:04:41] <PetefromTn_> but i just fabbed up a little 90 degree mount tab with the tig welder and tig welded the steel mounting threaded flange to that and wired it up... I put it between the column and the enclosure in about a six inch space to keep peoples fingers out of it.
[14:05:34] <zeeshan|2> 1500W element?
[14:05:55] <PetefromTn_> don't remember but we sized it to the specs on the VFD
[14:06:03] <zeeshan|2> okay
[14:06:10] <zeeshan|2> my prob is i wanna put element in an enclosure
[14:06:14] <zeeshan|2> it seems like a lot of work
[14:06:28] <zeeshan|2> http://i.ebayimg.com/00/s/NzUwWDEwMDA=/z/zFwAAOSweW5VLoTk/$_57.JPG
[14:06:31] <zeeshan|2> i came across this on ebay
[14:06:34] <zeeshan|2> looks very easy to mount
[14:06:37] <zeeshan|2> and work with
[14:06:41] <zeeshan|2> and has thermal switch
[14:06:45] <zeeshan|2> i cant decide wtf to do
[14:06:49] <zeeshan|2> as usual im overthinking
[14:43:05] <JT-Shop> better to let them touch it lol
[14:43:57] <Wolf_> still fighting the vfd?
[14:47:38] <Wolf_> zeeshan|2: space heater thing should work, a oil filled type should just have a standard heating element
[14:51:36] <Roguish> zeeshan|2 : be very careful if you're using a braking resistor. They usually get attached to the buss in side, which can be VERY high voltage 600+. that shit bites hard and does not let go.
[14:52:34] <Roguish> watch the wiring insulation rating also, and all the connections should be really well made.
[14:53:07] <Roguish> I put a set of resistors on a 10hp / 480v drive.
[15:01:44] <zeeshan|2> Roguish: got a link of what you used
[15:06:30] <Tom_itx> http://www.cressall.com/dynamic-braking/calculating-resistor-sizes/
[15:07:07] <zeeshan|2> tom dont be dork
[15:07:18] <zeeshan|2> :D
[15:07:28] <zeeshan|2> Roguish: also this is a 240v drive
[15:07:40] <zeeshan|2> it shouldnt exceed 240v i hope! :P
[15:07:42] <Wolf_> now that I had my fun filled day at traffic court, now to get back to this machine setup
[15:09:48] <Tom_itx> zeeshan|2 you didn't like the link?
[15:10:06] <zeeshan|2> Tom_itx: i dont know why you sent it is why i said that
[15:10:07] <zeeshan|2> hehe
[15:10:48] <zeeshan|2> im gonna try something
[15:10:59] <zeeshan|2> im gonna set the decel time to .2 s
[15:11:11] <zeeshan|2> and try to map out what freq it's okay upto
[15:13:03] <zeeshan|2> Tom_itx: did you build bellows for your sherline
[15:14:35] <PetefromTn_> http://i.imgur.com/2k1QrXG.jpg
[15:15:16] <zeeshan|2> PetefromTn_:
[15:15:17] <zeeshan|2> thank you!
[15:15:21] <Roguish> the internal buss voltage will most probably be greater than 240v. check with the mfg.
[15:15:22] <zeeshan|2> where did you get that element from?!?
[15:15:28] <zeeshan|2> Roguish: youre right
[15:15:32] <PetefromTn_> home depot i think
[15:15:34] <zeeshan|2> it should be 240* afactor
[15:15:37] <zeeshan|2> i think 340V or so.
[15:15:40] <zeeshan|2> still not 600!!
[15:15:51] <Roguish> just be careful.
[15:16:02] <zeeshan|2> Roguish: i appreciate the concern
[15:16:09] <zeeshan|2> but i was working on live 240v yesterday
[15:16:23] <zeeshan|2> i understand they are lethal voltages
[15:16:31] <zeeshan|2> im more concerned about it going on fire during operation
[15:16:34] <zeeshan|2> when im not paying attention
[15:16:41] <zeeshan|2> cause it's not cooled right
[15:16:44] <alex80> what are you doing ?
[15:16:53] <zeeshan|2> adding an external resistor to the vfd
[15:17:28] <alex80> why ?
[15:17:31] <alex80> breaking ?
[15:18:09] <zeeshan|2> yes
[15:20:23] <zeeshan|2> PetefromTn_: does this look similar:
[15:20:26] <zeeshan|2> http://www.homehardware.ca/en/rec/index.htm/Plumbing-Electrical/Plumbing/Repair-Hookup/Water-Heaters/Elements/120-Volt-1500-Watt-Screw-In-Water-Heater-Element/_/N-ntja6/R-I3285242
[15:20:39] <alex80> vfd's that can feed the power back into the grid are too expensive for your project ?
[15:21:11] <PetefromTn_> yeah it was something like that... not remembering the brand name. It definitely helped..
[15:21:17] <zeeshan|2> were you not worried
[15:21:23] <zeeshan|2> that it was seeing 350V
[15:21:28] <zeeshan|2> vs the 110VAC it's rated for?
[15:22:28] <PetefromTn_> honestly it is just a big resistor I guess and it has been on there for a good long time now without any problems. For you it might be an issue most likely tho I just wanted it to work
[15:22:44] <zeeshan|2> you have a nice place to hide it
[15:22:47] <zeeshan|2> so no one can touch it
[15:22:51] <zeeshan|2> i dont have a place like that :(
[15:22:58] <PetefromTn_> and I THINK mine was 230v
[15:23:14] <Roguish> zeeshan|2
http://imagebin.ca/v/2CbC9OF9EhVT
[15:23:20] <PetefromTn_> you are a Tig welder/fabricator just fab up something to keep it protected
[15:23:22] <zeeshan|2> Roguish: sexy!!
[15:23:27] <zeeshan|2> those are so expensive though!!
[15:23:35] <zeeshan|2> haha PetefromTn_
[15:23:39] <zeeshan|2> im lazy!!
[15:23:44] <PetefromTn_> yeah me too
[15:23:45] <Roguish> outdoor application. all the sheet metal was 316
[15:24:03] <Roguish> custom enclosure.
[15:24:04] <zeeshan|2> that is sexy
[15:24:10] <Wolf_> get a toe kick heater and mount it in that, so in the winter you can warm your feet with it
[15:24:22] <PetefromTn_> picked up the first job for the guys at the race shop stainless Tig... it's just a downpipe
[15:24:52] <zeeshan|2> nice!!
[15:24:56] <zeeshan|2> congrads man
[15:25:01] <PetefromTn_> they gave me a BUNCH of .045 ER308L rod and a bunch of more practice materials to play with. Some of that thin walled aluminum tubing too..
[15:25:42] <zeeshan|2> Roguish: did you buy thise resistors individually?
[15:25:42] <PetefromTn_> they also ordered me some .045 ER309L rod should be here tomorrow so I can do these things. Gonna just do the best I can to make it pretty and hopefully it will be enough
[15:26:03] <zeeshan|2> i'd just fusion weld the downpipe
[15:26:09] <zeeshan|2> except at flange
[15:26:17] <PetefromTn_> it's at the flange
[15:26:19] <Roguish> I used an AC Tech drive. resistors from them also. heavily oversized.
[15:26:22] <alex80> on a repair job i have seen a machine drive where someone had replaced the broken resistor by a hair dryer ...
[15:26:29] <PetefromTn_> they put a vee band on the bigass tube and tacked it.
[15:26:43] <PetefromTn_> I gotta finish weld it and try to make it as pretty as possible
[15:26:55] <zeeshan|2> alex nothing wrong with that
[15:26:59] <zeeshan|2> as long as it's rated for that voltage
[15:27:00] <zeeshan|2> and current
[15:27:20] <alex80> yes - but i was confused about the noise :)
[15:28:00] <Wolf_> really showdl work long as you don’t exceed the wattage I would think
[15:28:22] <zeeshan|2> my main concern is the voltage
[15:28:34] <zeeshan|2> a lot of things have insulation that can only handle a certain voltage
[15:28:40] <zeeshan|2> after that if you touch that insulation its game over
[15:28:41] <zeeshan|2> :D
[15:28:56] <zeeshan|2> but someone whos touching a heating element
[15:28:58] <zeeshan|2> is a dummy anyway :P
[15:29:09] <Wolf_> darwin at work
[15:29:38] <Wolf_> IMO they need to TAKE all the warning labels off of things
[15:33:29] <alex80> zeeshan|2, and the heating element is rated too low for your voltage ?
[15:38:37] <zeeshan-mill> yea
[15:38:40] <zeeshan-mill> but okay you know what
[15:38:44] <zeeshan-mill> i have the spindle at 500 rpm
[15:38:53] <zeeshan-mill> and it can decelerate to in 0.5 s no problem
[15:38:57] <zeeshan-mill> with the internal resistor
[15:39:11] <zeeshan-mill> i just need to figure out a way to change decel time for rpms > 500
[15:39:23] <zeeshan-mill> sounds like something i should be able to do in the vfd.
[16:10:20] <zeeshan-mill> YAYYYYYYYYYy
[16:10:21] <zeeshan-mill> its working!!
[16:10:24] <zeeshan-mill> without additional resistor
[16:10:40] <zeeshan-mill> ive setup 2 stages. anything above 20 hz the decel and accel time are longer
[16:10:50] <zeeshan-mill> anyting below 20hz it accels or decels in 0.5s
[16:10:59] <zeeshan-mill> its reversing correctly now
[16:14:19] <NephFL> Hello
[16:16:46] <zeeshan-mill> hi
[16:16:53] <zeeshan-mill> "joint 2 following error"
[16:16:53] <zeeshan-mill> hmm
[16:17:35] <NephFL> I have a few beginners questions when someone is around.
[16:17:44] <zeeshan-mill> just ask!
[16:18:31] <NephFL> Well, ok, first, I'm wondering if linuxcnc can be run on android or raspberry pi with USB devices to interface to break out boards, or even network based smoothstepper, etc?
[16:19:01] <cradek> nope
[16:19:18] <zeeshan-mill> cradek youre an expert on rigid tapping!
[16:19:19] <zeeshan-mill> help :P
[16:19:21] <NephFL> Is it something that just hasn't had much interest or is it an RTC issue?
[16:19:38] <zeeshan-mill> neph machinekit is taking care of that department
[16:20:06] <NephFL> is that a user, or company?
[16:20:18] <zeeshan-mill> cradek: i got the spindle reversing down to 0.5 s
[16:20:27] <NephFL> Like I said, I'm extremely new...not so much to electronics or concepts but to the community and this software
[16:20:30] <zeeshan-mill> i got k set to 0.03125
[16:20:41] <zeeshan-mill> but using a value of .09, i get joint 2 following error
[16:20:55] <zeeshan-mill> (simulating a 5/8-11 thread -- largest i'd ever do)
[16:21:08] <zeeshan-mill> NephFL, software
[16:21:50] <NephFL> ok, if it is machinekit.io, that looks like a little lower level than linuxcnc. I'm looking for gcode level interface for some converted mills I have.
[16:22:23] <cradek> NephFL: linuxcnc runs on PCs. The best hardware interfaces are PCI or PCI-express based
[16:22:44] <cradek> NephFL: there are also now ethernet-based solutions
[16:23:09] <cradek> NephFL: and many kinds of parallel-port based interfaces (EPP and not)
[16:23:12] <NephFL> Is there a linuxCNC post processor for HSMWorks?
[16:23:21] <cradek> I don't know
[16:23:45] <NephFL> Ok, I can check with HSMWorks/autodesk about that
[16:23:57] <NephFL> so, LinuxCNC is x86 dependant?
[16:24:13] <NephFL> it can't run on ARM environments?
[16:24:40] <CaptHindsight> it's been run on ARM
[16:24:58] <cradek> x86 and amd64 and yes some ARM but then the hardware support is poor
[16:24:59] <CaptHindsight> you just have to build it yourself
[16:25:03] <cradek> and the performance is usually poor too
[16:26:03] <NephFL> Ok, is there a equivalent ARM/Android type software (I know that isn't a LinuxCNC issue, but figure you guys would know better than me and Google, yes I checked)
[16:26:32] <cradek> what are you retrofitting?
[16:27:11] <Deejay> gn8
[16:28:47] <NephFL> I have a bridgeport that I put a PMDX control on and I have a Santec Bed mill that I put a DMM-Tech control on (both parallel breakout style servo controllers)
[16:29:48] <NephFL> but I'm getting really annoyed trying to get old pcs to work when I have tons of android tablets and raspi stuff laying around that are cheap and really should do the job
[16:30:09] <malcom2073> The problem isn't speed, it's timing reliability
[16:30:45] <malcom2073> You can't control step and direction without good timing
[16:31:08] <malcom2073> The beaglebone does a pretty good job of it, it's on the level of the pi
[16:31:25] <NephFL> I understand, but I would imagine that it shouldn't be horribly hard to use an external timing source or even offloading some of the control to the hardware. I understand there are even gcode interpreters for arduino. But raspi even has built in SPI, so one would think timing would be able to resolved there
[16:32:06] <cradek> NephFL: having watched many people go by, I don't think this path is going to make your job easier
[16:32:38] <NephFL> cool...since I'm new to any of this software, I just need to get my bearings as to where everyone has gone with this stuff
[16:32:39] <cradek> even a pentium III has better performance than those embedded boards
[16:32:57] <malcom2073> Offloading the control is fine and dandy, but you have tradeoffs (grbl does this to run on arduino)
[16:33:08] <cradek> so then you end up trying to offload the gui etc, and then you have several problems where you just started with one
[16:33:36] <NephFL> and everywhere I've looked CNC stuff looks pretty archaic in its implimentation and I don't know if there is just another direction they have gone or if it has just stayed where it is due to lack of interest or that the stuff on that side goes commercial
[16:33:46] <malcom2073> Archaic how?
[16:34:24] <cradek> malcom2073: doesn't look like cell phone/video game? it's true machinists are a very conservative bunch.
[16:34:34] <malcom2073> cradek: True heh
[16:34:41] <malcom2073> If you want fancy, look into machinekit
[16:34:45] <malcom2073> they have some snazzy GUI's now
[16:34:50] <CaptHindsight> NephFL: so you have an ARM device with integrated ethernet in the SOC (not on USB)?
[16:34:53] <NephFL> using a full x86 pc as a controller . a new x86 pc set up as a controller costs at least $200 or so...when I can get a touch screen tablet with wireless and everything for $50 that would look much slicker and give me better performance
[16:35:34] <CaptHindsight> so/do
[16:35:36] <NephFL> then, if I were a manufacturer, I could sell the controller in a tablet for a higher price than PC because it seems more advanced (which still works with some)
[16:35:36] <cradek> nobody retrofitting a bridgeport cares about $200 in hardware cost. They care about will it work for the next ten years
[16:36:10] <NephFL> that is what I figure, and am trying to find out...so it is really a lack of interest in advancement for the sake of advancement
[16:36:11] <cradek> nobody here cares about "seems more advanced" or sale price. we're free software folks and machinists.
[16:36:19] <NephFL> CNC markets are very practical...
[16:36:30] <NephFL> makes sense
[16:36:30] <Wolf_> NephFL: if you manage to make something like that work with a tablet please do a write up and send me a link
[16:36:49] <malcom2073> Indeed, tablets don't meet the timing requirements
[16:37:00] <malcom2073> You can for instance, run grbl on an arduino, and link it via USB to a tablet, and use that
[16:37:07] <malcom2073> But then you have to deal with grbl heh
[16:37:13] <Wolf_> first issue I see is lack of IO on the tablet
[16:37:27] <CaptHindsight> NephFL: there hasn't been mcu in the way of ARM boards/tablets/laptops that have real time IO and open GPU drivers
[16:37:34] <CaptHindsight> mcu/much
[16:37:41] <NephFL> I'm working with a board that is dual core 1+ghz with cellular radio, all sorts of sensors, built in video processor , lcd control, wifi, etc and it is a $50 part...and can run standard android stuff... just wonder if anyone has gone that way in this stuff
[16:37:58] <CaptHindsight> so you end up with the BBB and having to have the GUI on another machine
[16:38:06] <CaptHindsight> or similar
[16:38:14] <cradek> how do you connect that to your bridgeport? wifi?
[16:38:14] <NephFL> most arm stuff has a GPU with android drivers
[16:38:18] <malcom2073> Which fwiw, is how I run (BBB + display on another PC)
[16:38:23] <furrywolf> I'd never use a tablet for anything important. The hardware is the worst of the worst junk, with no repairability or upgradability. many don't even have replacable batteries. the software is usually mostly closed-source, with even open-source linux installation depending on binary blobs to make things work.
[16:38:42] <NephFL> Well, I have SPI, USB, GPIO, pretty much whatever you have in PC...
[16:38:57] <NephFL> the SPI is stable enough to coordinate full motion video
[16:39:13] <CaptHindsight> most ARM boards/tablets/laptops don't have integrated ethernet or a PCIe slot
[16:39:13] <NephFL> I can't imagine the timing of CNC is harder than that
[16:39:15] <cradek> spi might have some application
[16:39:25] <furrywolf> NephFL: nothing you've mentioned there is really useful for cnc control. wifi is useful for getting stuff onto it, and that's it. and you don't want to use it while running a machine.
[16:39:46] <furrywolf> you could make the spi talk to a mesa board for machine control
[16:40:04] <furrywolf> however, the firmware is usually pretty evil, with power management, etc fucking up timings.
[16:40:14] <furrywolf> like a pc laptop but worse.
[16:40:21] <CaptHindsight> NephFL: try an imx6 board with PCIe or ethernet and let us know how it works. I will when I get time.
[16:40:39] <NephFL> Nothing can really be "better" than what already works, but it can do the same thing with slicker UI and more features for connecting to systems like job tracking and work flows with engineering
[16:41:15] <furrywolf> every time I see people's ideas of "slicker" UIs, I think they must spend their time looking at their computers rather than using them.
[16:41:16] <CaptHindsight> the imx6 has the open GPU drivers, integrated ethernet and PCIe, so a choise of real time IO and a gpu powerful enough to run a GUI and has openish enough drivers
[16:41:34] <zeeshan-mill> damn it why is this giving me joint following errors
[16:41:39] <furrywolf> If you animate something, even something like making a box fade in/out instead of instantly appear/vanish, I will want to painfully injure you. :P
[16:41:42] <zeeshan-mill> i dont see anything fishy in halscope
[16:41:51] <NephFL> right now, I'm still just getting bearings of what is out there...I have lots of projects, so I can't focus too much on things, the ARM board is part of a different project that has to do with data aquasition...I'm just trying to think of how the projects can relate
[16:42:09] <furrywolf> UIs should be simple, high contrast, with controls of size suitable for observing from a distance.
[16:42:23] <malcom2073> Well recreating the wheel just to make it shinier is a quick path to *way* more projects heh
[16:42:56] * furrywolf thinks most modern UI "features" are a substantial step backwards in productivity and usability.
[16:43:11] <NephFL> I absolutely agree...one of the things I have done in my career is repair and keep up old dumb terminal systems for compliance, so that means working with monochrome serial based terminals, I don't see why many applications need any more...but I can see what people prefer to purchase
[16:43:37] <NephFL> yeah, one of the biggest problems I have is taking on too many projects before letting the other projects mature
[16:44:02] <malcom2073> Look at what Tormach did with their linuxcnc control programs: They made it pretty
[16:44:11] <NephFL> this project is only secondary to a machining project, lol...that is why my investigation is really idle speculation and research right now...aside from the fact that I need to get these controls up and running
[16:45:40] <NephFL> but I always end up doing random projects like this to make money and keep work interesting...like recently networking some CNC6 machines to upload data from ethernet..
[16:46:07] <furrywolf> looks like I didn't win anything yesterday. figured that'd be the case.
[16:46:07] <NephFL> so, there are no real open source arm programs that mirror linuxcnc or mach3, etc
[16:46:10] <furrywolf> sigh. I need a house.
[16:46:21] <malcom2073> NephFL: Read up. Machinekit
[16:46:44] <furrywolf> linuxcnc could be made to run on arm more efficiently, just needs someone to put in time and effort. thanks for volunteering! :P
[16:47:23] <NephFL> machinekit looks more like programable logic/networking than CNC , no? does it have a GCode interpreting interface with DRO type display?
[16:47:39] <malcom2073> NephFL: machinekit is a fork of linuxcnc
[16:47:40] <furrywolf> I'm not convinced, however, of the suitability of consumer ARM systems for running anything realtime.
[16:47:52] <malcom2073> A recent fork
[16:47:56] <NephFL> Oh, I must be looking at the wrong page, I'm looking at machinekit.io
[16:48:00] <furrywolf> crap hardware and crap firmware
[16:48:00] <malcom2073> Yes, that's them
[16:48:35] <malcom2073> machinekit suffers from the same syndrome that linuxcnc does: A lack of someone who knows how to design webpages :P
[16:48:56] <NephFL> I'm not looking necessarily at "consumer arm" systems, I work with electronics manufacturers and have some prototypes I'm working on as well, which is why I mentioned SPI
[16:49:15] <furrywolf> you mentioned an inexpensive consumer tablet. heh.
[16:49:19] <furrywolf> or someone did. /me forgets now
[16:49:27] <PetefromTn_> I really don't understand the need people have to try to run something as complex and dangerous as a CNC milling machine on a BBBor tablet... Just seems sorta insane to me
[16:49:32] <NephFL> I think linux also suffers from the idea that they want to keep usability somewhat low so that they can have some commercial success to survive
[16:50:29] <malcom2073> PetefromTn_: I did it for faster/better step rate
[16:50:31] <NephFL> @PetefromTn_ isn't LinuxCNC all about running the machines from a "consumer x86 PC" , those are certainly not designed for real time machine control
[16:50:36] <furrywolf> PetefromTn_: cell phones and tablets seem to be an obsession for some people
[16:50:37] <CaptHindsight> PetefromTn_: every try to use a desktop pc at the beach, a tablet makes much more sense :)
[16:51:09] <PetefromTn_> I have a drawer full of tablets and whatnot
[16:51:18] <PetefromTn_> never considered trying to run the VMC with any of them
[16:51:24] <NephFL> It looks like those ARM devices are the way everyone has gone, and there are some amazingly powerful SoC systems available at amazingly low cost.
[16:51:55] <PetefromTn_> LinuxCNC has been and always will be designed to run machines well beyond the hobby tabletop toys and can and does run masssively heavy equipment all day long reliably
[16:52:03] <malcom2073> Oh a tablet would be the wrong device, but the BBB is a different beast entirely
[16:52:25] <CaptHindsight> unfortunately the tablets left out PCIe and ethernet
[16:52:47] <CaptHindsight> and the gpu drivers ended up closed
[16:52:48] <PetefromTn_> with the availability of small format CHEAP main boards and whatnot I really don't see the advantage anyway
[16:53:07] <CaptHindsight> and the Linux distros available for them use magic tool chains
[16:53:15] <CaptHindsight> and are very broken
[16:53:16] <PetefromTn_> coupled with Mesanet Cards I cannot imagine going in any other direction for any sort of serious machine
[16:53:50] <furrywolf> my knowledge is a bit outdated, but my impression always has been those arm SoCs aren't nearly as powerful as their numbers claim, with a lot less cache, fewer instructions executed per clock cycle, branch prediction, etc, etc, etc, and all the other features expected in an x86 cpu. but, as I said, I might be relying on outdated knowledge.
[16:53:51] <CaptHindsight> an ARM tablet to control a simple lab robot or gantry would be handy
[16:53:52] <NephFL> seems youtube has some examples of machinekit with BBB
[16:54:10] <malcom2073> Yep it does
[16:54:27] <malcom2073> That's one of their primary targets afaik
[16:55:17] <NephFL> BBB and raspi are based on older slower chips with less features than you find in modern chipsets for things like mobile phones
[16:55:34] <furrywolf> If NephFL has an arm board with open-source and/or non-existant firmware and a good spi port, I'm willing to bet you could rather easily make it talk to a mesa board.
[16:55:35] <malcom2073> The PRU is what makes the BBB capable, not the fact that it's ARM
[16:55:49] <CaptHindsight> the BananaPi has integrated ethernet
[16:56:16] <CaptHindsight> and you can probably get 2D accel working fast enough for a GUI
[16:56:30] <furrywolf> that is, it shouldn't take much custom programming to make a mesa board take its inputs over spi.
[16:56:42] <NephFL> im not a big fan of the old broadcom chipsets on raspi stuff
[16:57:38] <furrywolf> you'll want a dedicated graphics controller, not something that'll take over main ram for random periods of time.
[16:57:52] <CaptHindsight> someone got a Samsung ARM soc on an Odroid working with Mesa over SPI
[16:58:20] <furrywolf> see? :)
[16:59:11] <furrywolf> I don't really see the point of trying to use arm systems though... x86 hardware is cheap and plentiful, plenty powerful, and a lot less faddish than any arm product.
[16:59:29] <furrywolf> arm stuff always seems to come and go, with absolutely no standardization between products of any kind.
[17:00:20] <NephFL> If you are a board designer though, arm is very attractive...
[17:00:59] <furrywolf> if you're a cnc machine designer, arm isn't. :P
[17:00:59] <NephFL> partially because it has such a big market share that the parts are extremely cheap
[17:01:39] <CaptHindsight> NephFL: which usable ARM parts?
[17:02:16] <furrywolf> if you design your own board, you're going to need to design your own software to go with it, as every arm system seems different enough that software for no other arm system will ever work.
[17:02:30] <furrywolf> while any x86 software runs on any x86 board anywhere.
[17:03:14] <NephFL> well, unless you can use some standard...like various serial/SPI is the most common , etc on android
[17:03:43] <furrywolf> android depends on binary blobs to the point where it's utterly useless without them.
[17:03:51] <NephFL> because SPI is standard for many LCDs almost all ARM systems do have plenty of SPI
[17:04:07] <NephFL> but what would be the ideal bus?
[17:04:21] <furrywolf> spi is fine, I don't recall ever saying it wasn't.
[17:04:30] <furrywolf> in fact, I even said it'd be easy to make a mesa product talk spi.
[17:05:00] <CaptHindsight> SPI, Ethernet and PCI/e all work with Mesa
[17:05:16] <NephFL> the chipsets for arm I have seen have SPI squared away for you by the chipset manufacturer for various android builds
[17:05:21] <Wolf_> just make sure its plug and play with something like Mesa and it might be a winner if it works
[17:05:34] <furrywolf> NephFL: of the blobular variety?
[17:05:46] * furrywolf dislikes binary blobs
[17:06:22] <furrywolf> also, while I've never tested it, I seriously doubt you can get the realtime performance you need out of any type of stock android system.
[17:06:39] <furrywolf> all power management, etc, will likely need to be killed.
[17:06:54] <furrywolf> cpu speed changes are particularly bad, even on x86...
[17:06:57] <NephFL> I have only seen the libraries on a directory level at this pint, lol, I'll be digging in soon, but I know that the gpio is direct address level, so I couldn't imagine the SPI isn't the same
[17:07:28] <Wolf_> would need custom rom/firmware/whatever its called on arm probably
[17:07:56] <NephFL> a custom rom/firmware is the same as installing any application on linux
[17:08:08] <zeeshan-mill> damn it still joint following errors
[17:08:09] <NephFL> meaning that anything that runs native in android is a custom rom
[17:08:13] <zeeshan-mill> i checked my Z tune
[17:08:15] <zeeshan-mill> and it looks god
[17:08:15] <CaptHindsight> how will you connect the SPI devices? solder wires to pads on the ARM tablet?
[17:08:17] <zeeshan-mill> *good
[17:08:57] <NephFL> @capthindsight I'm designing a board for a project, so I can make whatever header I like, or change it to RS232 or whatever levels you like
[17:09:14] <Wolf_> have something made with a plug on it… would be a neat venture to make a control head tablet
[17:09:14] <zeeshan-mill> http://i.imgur.com/zzOI2T8.png
[17:09:14] <CaptHindsight> NephFL: which ARM SOC?
[17:09:17] <zeeshan-mill> i get this massive spike
[17:09:18] <NephFL> I just don't know about the timing issues
[17:09:19] <furrywolf> one of the biggest issues, as I said, is compatibility... you don't want to have to re-write for every possible system it runs on. android, for example, each version will only run on a select set of devices, no older nor newer.
[17:09:19] <zeeshan-mill> on spindle reversal
[17:09:51] <NephFL> I've been looking at the MediaTek cell phone chipsets
[17:10:03] <furrywolf> you don't want to have to rewrite all your drivers because you got a newer tablet.
[17:10:21] <Wolf_> furrywolf: sounds like we are talking semi custom build tablet vs off the shelf
[17:10:48] <NephFL> No, this would be a purpose built device.
[17:11:13] <NephFL> Well, general purpose, because I'm working on using it in different data aquasition project
[17:11:26] <NephFL> but I can throw on any headers I like without costing me anything
[17:11:30] <CaptHindsight> NephFL: you'll run into driver and tool chain issues with Mediatek
[17:11:39] <NephFL> yeah, I already have
[17:12:09] <NephFL> its hard to even get someone who can talk to them, manufacturing is in china, management in Taiwan and never two shall the twain meet
[17:12:38] <CaptHindsight> Rockchip’s RK3288 is in the new Chromebooks, most drivers are there
[17:12:52] <furrywolf> if you build a custom board, you'll need to maintain drivers for it for future software versions as well.
[17:12:57] <NephFL> at this point, I'm basically hacking/reverse engeneering for the development I'm doing
[17:13:14] <NephFL> well, unless the MTK drivers will suffice..then they can maintain them
[17:14:35] <CaptHindsight> even Mediatek is having driver problems
[17:14:58] <CaptHindsight> http://www.extremetech.com/computing/200974-mediatek-may-license-amds-radeon-for-next-gen-smartphone-tablet-graphics-chip
[17:15:18] <CaptHindsight> why they might be using AMD for their next SOC's
[17:15:39] <CaptHindsight> even though AMD is having Linux driver issues of their own :)
[17:15:58] <NephFL> really, I don't have nearly enough info until I dig into that project more...
[17:18:45] <zeeshan-mill> does anyone know how to tell if you've set your acceleration values TOO high for a dc servo in linuxcnc?
[17:19:18] <SpeedEvil> zeeshan-mill: motor output level is pinned during moves?
[17:21:09] <zeeshan-mill> by output level
[17:21:29] <zeeshan-mill> you mean i need to monitor velocity of the servo
[17:21:37] <zeeshan-mill> and see if the rate of change of that doesnt change
[17:21:40] <zeeshan-mill> even though im asking it to
[17:22:42] <SpeedEvil> I should have been clearer - there will be a maximum current the drive can do - or a maximum voltage that can be applied across the motor.
[17:22:51] <SpeedEvil> If you hit that level, then it's open, not closed loop
[17:23:12] <zeeshan-mill> yes but how do i actually measure that
[17:32:23] <CaptHindsight> zeeshan-mill: if the axis flies off the machine and into the wall that's one possible way :)
[17:35:12] <PetefromTn_> working on my shop built 2x belt grinder a bit today...
[17:35:55] <PetefromTn_> making those pieces slide smoothly inside each other is always a big PIA.. I thought about taking it to the mill but just kept grinding until it fit okay heh
[17:36:29] <Tom_itx> grind it into tolerance
[17:36:38] <PetefromTn_> yeah right..
[17:36:50] <PetefromTn_> grind it til it fits and call it done more likely
[17:37:13] <Wolf_> get DOM tubes
[17:37:35] <PetefromTn_> it just gets a clamp screw in position but has to be able to slide relativley easily. The other one has the spring loaded mech so I need that one to fit even better I think.
[17:38:12] <PetefromTn_> naah this is square structural tube I had laying around here. I am using some thick walled stuff too hoping it willl make the machine a touch less vibration sensitive etc.
[17:39:03] <Wolf_> or mill some slots and add acetal strips to it
[17:39:28] <PetefromTn_> did you see the video of the machine I am building?
[17:39:33] <Wolf_> yeah
[17:39:51] <PetefromTn_> it's not exactly rocket science nor does it really need to be amazingly smooth in these adjustments
[17:40:03] <Wolf_> I’m thinking of doing one, but with only 3 wheels, don’t see why 4 are needed
[17:40:19] <PetefromTn_> what do you mean?
[17:40:29] <PetefromTn_> you have two different setups on the machine
[17:40:34] <PetefromTn_> one is a flat platen
[17:40:35] <Wolf_> oooh
[17:40:41] <PetefromTn_> the other is a large contour wheel
[17:40:45] <PetefromTn_> they interchange
[17:40:55] <Wolf_> I missed that part lol
[17:41:03] <PetefromTn_> making it able to reach into most spots
[17:41:10] <PetefromTn_> yeah that is part of what I like about it.
[17:41:43] <PetefromTn_> I also want to try to experiment with making some tube specific wheels so I can try to do some belt grinder notching stuff
[17:41:51] <PetefromTn_> or at least clean up the notches I cut in other ways
[17:42:39] <PetefromTn_> it's not a big deal but I can see a lot of ways that little machine can make my life easier around the shop.
[17:42:48] <Wolf_> what I meant was to get some tube with a sloppy fit and add a shallow slot + acetal strips to help the slide + fit
[17:42:52] <PetefromTn_> especially the more I get work with the Tig welding of this tube stuff
[17:43:03] <PetefromTn_> yeah I know
[17:43:07] <PetefromTn_> its a good idea actually
[17:43:43] <Wolf_> or do it tow truck style and bolt the pads on lol
[17:43:53] <PetefromTn_> I was planning to just carefully sand the shaft for the spring loaded bit until it fits nice and smooth and then put some heavy grease in the socket to help it more
[17:44:29] <PetefromTn_> once I get the sliding bits done I will start welding the whole thing together
[17:44:55] <PetefromTn_> I was THINKING of trying to buy a used skateboard and use the wheels like some folks did for the idlers...
[17:45:04] <Wolf_> one of my fav things to have laying around in the shop is 2.5” DOM square w/ .25” wall (trailer hitch tube)
[17:45:29] <PetefromTn_> this stuff is 3/8 wall for the base
[17:45:31] <Wolf_> used? skate board wheels should be cheap lol
[17:45:42] <PetefromTn_> 1/4 for the sliding bits
[17:45:52] <PetefromTn_> no idea about the wheels
[17:46:13] <PetefromTn_> but if you buy a whole skateboard used for $20 you get the trucks, four wheels, etc etc.
[17:46:18] <Wolf_> what belt width?
[17:46:36] <PetefromTn_> I think they use 2x73 or something like that
[17:47:22] <Wolf_> check to see if there is a skateboard shop in town
[17:47:43] <PetefromTn_> Oh I am sure there is...
[17:47:51] <PetefromTn_> new wheels and bearings would be nice
[17:50:45] <PetefromTn_> https://www.youtube.com/watch?v=L8ss_PZDWP0 This one he used steel wheels and automotive serpentine belt idlers modified but the skate wheels would work the same way
[17:51:15] <Wolf_> yeah
[17:52:06] <Wolf_> what diam wheel are you thinking?
[17:53:33] <Wolf_> have from 48mm - 76mm looks like
[17:54:59] <PetefromTn_> for the main idlers I don't really care I will just adjust the frame to work with whatever based on the belt length
[17:55:24] <PetefromTn_> for the tube notching I will have to take some measurements with what I do have once it is working to see what I need
[17:55:34] <PetefromTn_> I don't even have a belt here yet LOL just started building it.
[17:55:51] <Wolf_> lol
[17:55:54] <Tom_itx> you know what belt lengths are available?
[17:55:59] <Tom_itx> or cheaper than others...
[17:56:04] <NephFL> has anyone tried to switch a spindle from the quickchange on a bridgeport bossCNC type setup back to R8? I'm wondering if there is a longer spindle or one that is hollow so that I can share tooling without doing all quickchange tooling.
[17:56:33] <Tom_itx> not sure why you'd want to
[17:56:48] <andypugh> Quite. R8 is relatively painful
[17:57:05] <Tom_itx> you can get collet sets for the quickchange as well
[17:57:30] <Tom_itx> wouldn't be any more difficult than the R8 setup
[17:58:04] <Tom_itx> we used to line the holders up on the table in order
[17:58:48] <NephFL> yeah, I just have tools and holders already for what im working on and it would be easier if it was just direct swapping jobs instead of having to have a seperate set of holders for that machine
[17:59:29] <NephFL> the quickchange isn't incredibly expensive, but I'm not profitable and so the lowest price is the best one
[18:00:09] <Tom_itx> would likely cost alot more to switch to R8
[18:00:54] <NephFL> ok...yeah, i didn't realize the length difference until I tried a standard spindle...so, I have to go back to the quickchange, just didn't want to have to buy tons more tooling
[18:00:54] <andypugh> R8 needs a lot of headroom to extract it too.
[18:02:09] <andypugh> You might get lucky on eBay. I found 35 holders (BT30 in my case) for £80 a while ago.
[18:02:58] <PetefromTn_> Tom_itx the belts are 2x72 apparently they are a common size for the knife maker crowd and others
[18:04:45] <Tom_itx> what's optimum ft/min on a belt?
[18:13:22] <PetefromTn_> heh no earthly idea... was planning on a variable speed setup
[18:19:40] <PetefromTn_> SOB...
[18:20:08] <PetefromTn_> I ordered that damn Tee fitting for the flow regulator for back purge at the same exact time I ordered the flow regulator
[18:20:20] <PetefromTn_> the Flow regulator came from a farther distance
[18:20:28] <PetefromTn_> I received it yesterday
[18:20:43] <PetefromTn_> STILL have not received a valid tracking number for the Tee fitting..
[18:20:54] <PetefromTn_> its supposed to be here by friday
[18:21:14] <PetefromTn_> sheeeeeeiiit
[18:23:21] <jdh> no local parker store or the like?
[18:23:32] <PetefromTn_> parker?
[18:23:59] <jdh> they make fittings of all types
[18:24:00] <PetefromTn_> besides I spent all of my spare cash on all of this stuff I bought lately.. even if I wanted to buy another one locally I am screwed LOL
[18:24:33] <jdh> http://www.powellfluidconnectors.com/id27.html
[18:25:32] <jdh> I probably have $5k+ in parker/swagelok/hamlet/etc SS fittings, valves, etc.
[18:26:20] <jdh> I buy ones that look like they might be useful when they are cheap
[18:27:56] <Wolf_> parker stores are rape prices tho
[18:28:18] <jdh> sure, but convenient
[18:28:32] <jdh> I go there for oddball stuff.
[18:28:35] <Wolf_> part of the reason I bought a karrycrimp
[18:29:04] <Wolf_> $2k for a crimper, probably paid for itself after 6 hoses made
[18:29:45] <jdh> the place here with the parkerstore does hoses. I have had maybe 6 hoses made there over a 2 year period. I think 4 of them failed on first use.
[18:30:19] <Wolf_> lol, last time I had 1 hose made, cost $180 I think
[18:31:04] <jdh> don't recall the cost. Fairly cheap though. Usually 1/4" fittings, 2-6ft teflon cored stainless braid
[18:31:18] <jdh> price wasn't bad, but the quality was pathetic
[18:31:30] <Wolf_> mine was a 5/8” rated for 5k psi
[18:31:57] <Wolf_> 20’ IIRC
[18:33:28] <jdh> http://www.artichoke.org/jjpg/fill.jpg That was Rev2
[18:34:50] <Wolf_> what am I looking at lol
[18:35:10] <jdh> gas fill panel for diving tanks
[18:35:26] <Wolf_> ahh ok
[18:35:31] <jdh> before I got enough fittings for rev3
[18:36:41] <jdh> I probably have 10 T's suitable for Pete in my box of pre-rev5 fittings
[18:54:35] <Wolf_> well, this should fix one part of my lead screw issues
http://i.imgur.com/SUkjjeu.png?1
[19:11:08] <andypugh> Is there a reduced-diamter part in the middle of the block?
[19:17:10] <Wolf_> yeah, just counter bored the original block for the thrust bearings
[19:26:42] <Wolf_> well, in the cad anyways, going to reuse the original blocks
[19:27:42] <andypugh> You could possibly get a needle roller in there between the thrust bearings.
[19:27:50] <andypugh> (Or use AC bearings)
[19:29:18] <flyback> I saw some wiki today on passive magnetic bearings
[19:29:48] <Wolf_> I was going to use AC bearings but was having issues finding 8mm bore
[19:31:38] <andypugh> Have a look for E8 magneto bearings
[19:33:46] <Wolf_> hmm
[19:35:13] <Wolf_> $7.78 each + $4.66SH
[19:35:50] <Wolf_> plus a week or two to get here
[19:37:13] <andypugh> 2 weeks? Where are you? Outer Mongolia?
[19:37:36] <jdh> Try UPS
[19:37:37] <Wolf_> USA, so might be a week
[19:38:58] <andypugh> Where are you buying from?
[19:39:19] <Wolf_> only ones that showed up are in UK
[19:41:31] <andypugh> How odd
[19:44:09] <andypugh> Maybe ask at an actual bearing shop?
[19:44:26] <andypugh> Anyway, time to sleep.
[19:47:39] <flyback> http://hackaday.com/2015/08/18/reflow-solder-your-micro-sd-to-ensure-it-doesnt-go-anywhere/
[19:50:34] <Wolf_> well, thats different
[19:51:19] <flyback> THAT'S WHAT SHE SAID
[20:01:04] <t12> i got a llambrich tailstock chuck
[20:01:07] <t12> it appears very nice
[20:06:48] <zeeshan|2> i dont need an external resistor
[20:06:49] <zeeshan|2> hooray
[20:07:32] <zeeshan|2> https://www.youtube.com/watch?v=O8zq2KTam-Y
[20:11:43] <malcom2073> Nice
[20:13:40] <Tom_itx> had a look a the CATIA manual today
[20:13:53] <jdh> buying a seat?
[20:14:02] <Tom_itx> kid is taking it in school
[20:14:08] <jdh> cool
[20:14:11] <Tom_itx> i could get it for 99
[20:14:15] <Tom_itx> for limited time
[20:14:31] <Tom_itx> i see some things i like better than solidworks
[20:14:58] <Tom_itx> switching from the model to sketch is more streamlined
[20:15:15] <Tom_itx> you define features all on the same screen
[20:16:12] <jdh> http://www.flir.com/flirone/display/?id=69324
[20:16:53] <Tom_itx> cool
[20:17:06] <Tom_itx> what's a regular flir camera cost?
[20:17:57] <Tom_itx> https://www.youtube.com/watch?v=wRrf1hvBBI8
[20:18:13] <Tom_itx> i watched that one all the way thru and found it pretty interesting in comarison
[20:28:38] <Tom_itx> jdh, do you use solidworks?
[20:29:10] <jdh> nope. my kid took a SW class a couple of semesters ago
[20:29:41] <Tom_itx> i was considering it myself but didn't sign up
[20:29:57] <jdh> whole semester, full price class.
[20:30:06] <Tom_itx> they've got catia, solidworks, mastercam etc at the vo tech
[20:30:59] <Tom_itx> our state gives good incentives for HS kids to get into it to boost the local labor force here
[20:32:21] <malcom2073> I enjoy solidworks, keeping an eye out for an alternative if I leave my job and lose my seat though
[20:32:39] <Tom_itx> i'm actually pretty impressed with CATIA so far
[20:32:49] <Tom_itx> it's just as expensive if not more though
[20:32:53] <malcom2073> Heh
[20:33:05] <Tom_itx> all the good ones are
[20:33:08] <jdh> I thought it was much much more
[20:33:25] <Tom_itx> i know my bud gave 75k for a seat 20 yrs ago
[20:33:44] <jdh> probably can only rent one now
[20:33:45] <Tom_itx> but it was on a sun box back then
[20:33:54] <Tom_itx> i'm pretty sure it's on windows now
[20:34:09] <Tom_itx> i'm not sure what the run it on at the school
[20:34:57] <membiblio> Is there a way to work around the Debian Wheezy live install issue where the installer complains that the kernel version to be installed does not match the kernel version of the installer and does not recommend continuing?
[20:36:04] <membiblio> And it seems the latest Debian version won't run in live mode either.
[20:38:40] <Tom_itx> did you try the latest 2.7~pre7 iso?
[20:38:47] <Tom_itx> it may not be any different but you could try it
[20:39:38] <membiblio> Tom_itz is that on the website?
[20:40:48] <Tom_itx> yeah in a certain spot...
[20:41:21] <membiblio> Tom_itx - do you have any idea where that certain secret spot might be?
[20:41:28] <Tom_itx> trying to find it
[20:41:40] <membiblio> Tom_itx - ok thank you
[20:45:08] <membiblio> Tom_itx - it looks like you install 2.6 and then add a apt source and then update from within.
[20:45:21] <Tom_itx> apparently the iso isn't updated yet
[20:45:28] <membiblio> Tom_itx - let me try that - perhaps my media was bad. (Hoping)
[20:45:33] <membiblio> Tom_itx - thank you.
[20:45:43] <membiblio> Here was the announcement of 2.7:
[20:45:45] <Tom_itx> http://linuxcnc.org/docs/2.7/html/getting-started/getting-linuxcnc.html#_installing_on_ubuntu_precise
[20:45:56] <membiblio> http://linuxcnc.org/index.php/english/forum/29-forum-announcements/28751-linuxcnc-27pre
[20:46:01] <Tom_itx> membiblio, i'm running the 2.7 pre7 on mine
[20:46:39] <PetefromTn_> Jeez man I get nutz when I read people describe the item they are selling on craiglist as Immaculant..... as far as I know that is not even a word right??
[20:46:51] <Tom_itx> did you try sudo apt-get update && apt-get dist-upgrade
[20:47:13] <Tom_itx> after you enter the target in software sources?
[20:47:40] <membiblio> Tom_itx - I need to install 2.6 first - I was having a issue getting the 2.7 live to run or install. Like I said - perhaps bad media. I will try burning dvd again.
[20:47:57] <Tom_itx> you moving from 2.5?
[20:48:03] <Tom_itx> if so you can't skip 2.6
[20:48:14] <Tom_itx> after you install 2.6 you can install 2.7
[20:48:40] <membiblio> I'm on 2.6 but I was looking at the ubuntu version and now I would like to look at debian because it seems that is where the developers are at.
[20:48:48] <Tom_itx> why?
[20:49:03] <Tom_itx> they have 3 or 4 versions i think
[20:49:12] <membiblio> Why what?
[20:49:20] <Tom_itx> why debian?
[20:49:39] <membiblio> Tom_itx are you running deb or ubu?
[20:49:54] <Tom_itx> i'm still running on ubuntu lucid
[20:49:57] <Tom_itx> 10.04
[20:50:01] <Tom_itx> :D
[20:50:11] <Tom_itx> but i have a ssd with wheezy on it
[20:51:00] <Tom_itx> http://www.linuxcnc.org/docs/2.7/html/getting-started/index.html#_updating_linuxcnc
[20:51:49] <zeeshan|2> Tom_itx: how dare you put down solidworks in the name of catia
[20:53:05] <Tom_itx> zeeshan|2, i wasn't
[20:53:17] <Tom_itx> but some features of catia look pretty nice
[20:53:51] <Tom_itx> this is mostly a CATIA town too
[20:54:52] <zeeshan|2> same here man
[20:54:55] <zeeshan|2> im just kidding
[20:54:59] <zeeshan|2> all the big boys use nx and catia
[20:55:15] <zeeshan|2> smaller to medium use solidworks it seems like
[20:55:19] <zeeshan|2> and inventor
[20:58:41] <Wolf_> so, when I install linuxcnc in the next day or two, use the 2.7-wheezy iso?
[20:58:43] <zeeshan|2> pcw_home: when you get a chance: i have 7W 24VDC solenoid that i'd like to switch directly using the mesa output. it requires 290~mA of current -- do you foresee any bad things happening to 7i77?
[20:58:51] <zeeshan|2> wolf there is a 2.7 iso?
[20:59:31] <Wolf_> I see a link in that getting started thing
[21:00:34] <zeeshan|2> i need to upgrade
[21:00:39] <zeeshan|2> maybe will doi it in a couple weeks
[21:01:13] <Wolf_> I’ll be doing my install tomorrow after I put the new vid card in the computer
[21:01:59] <zeeshan|2> nice
[21:02:52] <Wolf_> steppers kit should be here friday I think
[21:04:04] <Wolf_> bearings, couplers and mill bits tomorrow too
[21:06:56] <Wolf_> wonder if I should try a ghetto low backlash nut for the lead screws…
[21:14:33] <Wolf_> that flir one… I don’t know, image quality kinda sucks on them
[21:16:29] <Tom_itx> zeeshan|2 i think there's a 2.7 iso but it's not the very latest pre7
[21:19:33] <Tom_itx> http://linuxcnc.org/docs/2.7/html/getting-started/getting-linuxcnc.html
[21:19:57] <zeeshan|2> im still on 10.04
[21:19:59] <zeeshan|2> for both my comps
[21:19:59] <zeeshan|2> :[
[21:20:07] <zeeshan|2> ill need to get on wheezy first
[21:20:09] <Tom_itx> me too
[21:20:12] <zeeshan|2> oh really?
[21:20:18] <zeeshan|2> and you got 2.7 running?
[21:20:18] <Tom_itx> i'm running the latest 2.7 pre7
[21:20:21] <zeeshan|2> yay!
[21:20:23] <zeeshan|2> good to know
[21:20:30] <zeeshan|2> maybe ill upgrade it soon
[21:20:38] <zeeshan|2> is there any major changes that are needed in the ini
[21:20:39] <zeeshan|2> or hal files
[21:20:45] <zeeshan|2> or it should work out of the box
[21:21:11] <zeeshan|2> did you use update manager?
[21:21:13] <Tom_itx> you'll have to use apt get to update it though
[21:21:24] <Tom_itx> software sources
[21:21:27] <Tom_itx> add it there
[21:21:34] <Tom_itx> then do the apt-get update
[21:21:42] <zeeshan|2> ok nso add apt source
[21:21:45] <zeeshan|2> i forgot what 10.04 was called
[21:21:49] <zeeshan|2> lucid
[21:21:53] <Tom_itx> 10.04 update manager doesn't work now since it's outdated
[21:21:55] <zeeshan|2> or precise? :P
[21:22:03] <Tom_itx> lucid
[21:22:09] <zeeshan|2> hmm maybe ill upgrade tonight
[21:22:22] <Tom_itx> pretty painless
[21:22:23] <zeeshan|2> help by testing :P
[21:22:34] <zeeshan|2> i gotta get groceries and make dinner
[21:22:35] <zeeshan|2> ill be back :P
[21:22:36] <PetefromTn_> hey guys I was wondering if you could give me your opinions of something about my rails I am making here...
[21:22:45] <zeeshan|2> damn it pete
[21:22:48] <zeeshan|2> just as im leaving!! :P
[21:22:56] <PetefromTn_> oh sorry man
[21:22:59] <Tom_itx> oh shut it and sit down
[21:23:00] <zeeshan|2> haha im kiddin
[21:23:16] <zeeshan|2> i really enjoyed messing with linuxcnc today
[21:23:19] <PetefromTn_> I just RE-anodized this part I was working on that screwed up the last time
[21:23:54] <PetefromTn_> and I am trying to decide which pic to put on my pages..
[21:24:58] <PetefromTn_> http://imgur.com/a/FOaMm Because I had to strip the part it is not as smooth as before but it at least is completely black without any problems
[21:25:19] <Tom_itx> zeeshan|2, after you add it to software sources do: sudo apt-get update && apt-get dist-upgrade
[21:25:32] <PetefromTn_> which pic looks the best to you?
[21:25:49] <PetefromTn_> I think you can see some specs of paper from the paper towel I wiped it down with LOL
[21:25:50] <jdh> last one
[21:26:18] <PetefromTn_> last one OK if you had to pick two/
[21:26:34] <Wolf_> like the ones on the granite block, but needs more lighting :P
[21:26:35] <zeeshan|2> last 2
[21:26:49] <PetefromTn_> the granite shows it better than the red cloth I guess
[21:26:56] <Wolf_> and what does that rail fit on?
[21:27:19] <PetefromTn_> I was trying to decide because I want to start showing all my parts in a similar setup so people can see the differences better
[21:27:35] <Tom_itx> PetefromTn_, i've found doing pics use a contrasting background and use 2 light sources using daylight bulbs
[21:27:54] <PetefromTn_> I am NO pro photographer that much is clear
[21:28:00] <Wolf_> ^ lighting helps a lot
[21:28:04] <PetefromTn_> but it is important that I show the parts in their best light
[21:28:41] <PetefromTn_> Wolf_ This is a custom Drop compensated Picatinny mount Scope riser rail that is designed to fit the Steyr LG precision air rifles....
[21:29:00] <Tom_itx> i have some pretty crude setups but i stick to that philosophy
[21:29:24] <Tom_itx> move the 2 sources around until you get the shadows where you want them
[21:29:30] <Wolf_> I almost know how to work a camera
http://i1139.photobucket.com/albums/n541/wolfmetalfab/Reloading%20stuff/IMG_2213.jpg
[21:30:21] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/boards/USBTiny_Mkii/USBTinyMkII_Blue.jpg
[21:30:26] <Tom_itx> limited shadows
[21:31:41] <PetefromTn_> I don't even have proper lighting in my shop let alone for my pictures... what kind of lights are you using?
[21:32:02] <Tom_itx> desk lamp with a daylight bulb
[21:32:18] <PetefromTn_> OK
[21:32:21] <Wolf_> just get some cheap ass clamp lights and daylight (high color temp) bulbs
[21:32:25] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/mega128.jpg
[21:32:28] <Tom_itx> shitty pic with flash
[21:32:48] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/mini_usb_batch1.jpg
[21:32:51] <Tom_itx> better lighting
[21:33:00] <PetefromTn_> I need to get a nice light for the Tig welding table
[21:33:20] <Wolf_> amazon 25w led flood light, $25
[21:33:31] <Tom_itx> you'll get better pics with daylight bulbs
[21:33:53] <PetefromTn_> I will check into some when I hit the box store next time..
[21:33:57] <PetefromTn_> appreciate the feedback guys
[21:34:03] <Tom_itx> they're cheap
[21:34:32] <Wolf_> or you can send me parts and I’ll take pics of them (if they fit stuff I have ;P )
[21:34:38] <Tom_itx> alot of mine were shot with a nikon D80
[21:35:01] <PetefromTn_> LOL right now I am quite literally tapped out I spent way too much on Tig supplies and household renovations stuff and I kinda screwed the pooch for this week unless I can get some jobs done here.
[21:35:19] <Tom_itx> you got lamps around the house...
[21:35:20] <PetefromTn_> that pic was taken with my LG G3 cellphone
[21:35:21] <Tom_itx> use em
[21:35:22] <Tom_itx> i do
[21:35:40] <Tom_itx> just steady the camera
[21:35:41] <Wolf_> I use a canon 550D
[21:35:48] <PetefromTn_> I do too just don't have daylight bulbs
[21:35:52] <Tom_itx> that makes a big difference too
[21:35:59] <PetefromTn_> I do have a nice tripod here
[21:36:11] <Tom_itx> try with regular bulbs but daylight give better results
[21:36:24] <Tom_itx> i was looking for a comparison here
[21:36:40] <Wolf_> better color in the photos
[21:37:54] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/hood2.jpg
[21:38:02] <Tom_itx> that's probably crap lighting
[21:38:04] <PetefromTn_> overall what do you think of the anodizing?
[21:38:07] <Wolf_> but 90% of the photos I link online are cellphone pics, but same rules apply, extra lighting at the desk when I take them
[21:38:18] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/rs232_2.jpg
[21:38:22] <Tom_itx> better lighting
[21:38:50] <Wolf_> anno looks good
[21:38:51] <Tom_itx> PetefromTn_ i think the anodizing looks good
[21:39:07] <PetefromTn_> I honestly thought I screwed this part to death here...
[21:39:18] <Wolf_> I really want to learn to do that
[21:39:33] <Tom_itx> you don't have to have a $$$ setup to get good pics
[21:39:35] <PetefromTn_> the first time I anodized it the black was PERFECT but it had a tiny void in a conspicuous spot
[21:39:58] <Tom_itx> just keep the glare out of the lens
[21:40:00] <PetefromTn_> so after trying to hand touch it up and failing miserably I had no choice but to redo it
[21:40:06] <Tom_itx> i usually do a side and front light
[21:40:24] <PetefromTn_> I had to put it in the lye bath for quite awhile before it started losing the color....
[21:40:25] <Tom_itx> or a shadow box
[21:40:36] <Tom_itx> ie white paper around what i'm shooting
[21:40:50] <PetefromTn_> then I sprayed it off and had to scrub the black off in the little nooks and crannies
[21:40:57] <PetefromTn_> it was a real pain in the ass
[21:41:14] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/boards/USBTiny_Mkii/USBTinyMkII_1-1c_top.jpg
[21:41:19] <Tom_itx> that was sitting on white paper
[21:41:25] <PetefromTn_> but I got it completely stripped and then I sorta re-brushed the brushed finish before I did the anodizing again...
[21:41:47] <Wolf_> this is under regular light bulbs
http://i1139.photobucket.com/albums/n541/wolfmetalfab/22%20race/IMG_2547.jpg but shot on my desk, used a camera bag for the background
[21:42:05] <PetefromTn_> what really scared me was the fact that after it sat in the acid anodizing bath for the required time and I cleaned it and popped it in the color bath
[21:42:18] <PetefromTn_> it took a LOOOOONNNNGGGG time before it started to take the color on.
[21:42:28] <Tom_itx> seriously though the parts look good but the pics are poor
[21:42:37] <PetefromTn_> it literally sat in the black dye for over an hour before it finally looked black enough to seal it
[21:42:38] <Tom_itx> move the lights around a bit
[21:42:50] <PetefromTn_> Tom_itx Yeah I will when I get a minute
[21:42:55] <Wolf_> I’ve seen worse anno on parts that I have paid for
[21:42:58] <Tom_itx> just grab 2 lights from somewhere
[21:43:08] <PetefromTn_> worse?
[21:43:16] <PetefromTn_> do you see a problem?
[21:43:25] <Wolf_> re-read :P
[21:43:53] <PetefromTn_> I am new to the anodizing honestly so I am really after honest reviews here
[21:44:09] <PetefromTn_> to be frank it is kind of a pain in the ass really..
[21:44:25] <Wolf_> I bought stuff that came with worse anno jobs on them
[21:44:27] <PetefromTn_> I have been able to make it look decent several times now but it does not come without a bunch of drama
[21:44:54] <Tom_itx> i'd light those from the side to eliminate the shadows
[21:44:55] <PetefromTn_> like this one that had just a tiny spot that did not take the color. REALLY pissed me off
[21:45:02] <Tom_itx> both sides
[21:45:28] <Tom_itx> then put the camera so you don't get reflections on them
[21:45:31] <PetefromTn_> the pictures do not do them justice I think.. they look pretty good in person.
[21:45:47] <Tom_itx> i'm tellin ya how to make em look good
[21:45:56] <PetefromTn_> and I am hearing ya man!
[21:46:10] <Tom_itx> i'd even go with a lighter background
[21:46:17] <Tom_itx> if you like the red that's fine...
[21:46:31] <PetefromTn_> I have a light cloth I have taken pics of stuff on before...it works good
[21:46:32] <Tom_itx> you don't want the background to interfere with the product
[21:46:50] <Tom_itx> i literally just use sheets of paper sometimes
[21:46:55] <Wolf_> pillow case, board, bathroom sink, usually good lighting there
[21:48:33] <Wolf_> at least the item is small enough to move to better lighting
[21:48:46] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/boards/USBTiny_Mkii/new_kits/USBTinyMkII_blue_full_kit_desc.jpg
[21:48:50] <Tom_itx> white paper backdrop
[21:48:51] <PetefromTn_> yeah it is about ten inches long
[21:49:28] <PetefromTn_> Lemme try another pic here gimme a few minutes
[21:49:43] <Wolf_> won’t fit in a light box
http://i.imgur.com/1TXiNMO.jpg
[21:50:06] <Tom_itx> hardly worth a pic.. :D
[21:50:21] <Tom_itx> cheby guy here
[21:50:37] <Wolf_> customer truck…
[21:50:45] <Wolf_> but mine is a ford too lol
[21:51:22] <Tom_itx> yeah my bud had a crewcab powerstroke for quite a while
[21:51:54] <Wolf_> oh and the thermal cam stuff, low rez sucks but $$ for higher
http://i.imgur.com/S3ap9WE.jpg
[21:53:55] <fenn> when photographing dark black stuff sometimes a white background can make auto exposure cameras do stupid stuff
[21:54:09] <fenn> so i'd stick with the granite plate
[21:54:25] <fenn> also it has a cool "machine shop" look :P
[21:54:35] <fenn> the red cloth reminds me of a grandma
[21:54:50] <Wolf_> ^ what fenn said lol
[21:57:21] <Tom_itx> i'd try a few different backdrops until you find one you like
[21:57:46] <fenn> i would be concerned about the rit dye fading in sunlight
[21:59:46] <PetefromTn_> damn camera is dead
[21:59:54] <PetefromTn_> gonna charge it here for a bit
[22:00:30] <Tom_itx> i sometimes pre trigger the camera so the light is set then turn on the side lights
[22:00:36] <Tom_itx> helps with washing out sometimes
[22:00:48] <PetefromTn_> fenn ya know I have heard people say it fades and others say it does not... I am not too concerned about it as these guns that they go on are not the kind of thing people leave outside for longer than it takes to shoot a match
[22:02:43] <PetefromTn_> all I do know is that I have done a bunch of parts with this black and a couple are banging around in the shop right now.. It is pretty nice deep black and is the look I am after here for the parts. time will tell if there is indeed a problem. Judging by how long it took even the lye solution to remove it or even barely penetrate it I can say it is pretty stout
[22:07:36] <Tom_itx> PetefromTn_, stick one outside in the sun for a while
[22:07:42] <Tom_itx> a scrap piece
[22:08:40] <Tom_itx> send it to andy and let him run it thru that weather chamber they have :)
[22:08:55] <PetefromTn_> I was chatting with the guys at the race shop about anodizing...
[22:09:29] <PetefromTn_> they were telling me how even when they pay good money and send it to pro shops the parts all fade
[22:09:40] <PetefromTn_> especially the ones under the hood
[22:09:51] <PetefromTn_> they showed me some red parts that are now quite pink LOL
[22:10:02] <Tom_itx> pretty sure the sun will fade just about anything
[22:12:15] <Tom_itx> years ago i worked at coleman and they would throw their canoes on the roof and leave em there a long long time
[22:20:08] <fenn> i had heard you couldn't anodize aluminum castings because of the silicon content but yesterday i found "CRO black" which says it is made for high silicon aluminum alloys
[22:20:34] <fenn> has anyone here used CRO black on castings and did it work?
[22:26:38] <fenn> or any success stories anodizing aluminum castings
[22:26:45] <PetefromTn_> I must say that I am very pleased that rail came out good the second time I have a lot of other things needing my attention in the shop tomorrow and having to either remake this part or RE RE anodize would have been a real nightmare LOL
[22:29:06] <PetefromTn_> I also realized that my rack I made for holding the parts in the tanks is a piece of junk and needs to be redesigned
[22:29:37] <PetefromTn_> it would also be real nice if it was able to be moved between the acid bath and the color and sealer tanks and work the same way
[22:30:19] <PetefromTn_> but no I have never tried to anodize a casting of any sort fenn sorry
[22:32:29] <Wolf_> anyone running a touch screen on linuxcnc?
[22:32:49] <PetefromTn_> cradek has one I think
[22:36:50] <CaptHindsight> Wolf_: yes
[22:38:04] <Wolf_> what brand? looking at some on eBay, I’m short a monitor for the cnc station. touchscreen worth the hassle?
[22:40:27] * flyback bites Tom_itx
[22:40:43] <Roguish> Wolf: touchscreen? be sure compatible/supported in linux.
[22:43:23] <PetefromTn_> http://www.ebay.com/itm/Combo-70mm-Longboard-Wheels-Black-BK-Abec-7-Skateboard-Bearing-/171674040624?hash=item27f891f930 wonder if this would work for the idlers on the belt grinder
[22:43:34] <CaptHindsight> Wolf_:
http://www.newegg.com/Product/Product.aspx?Item=N82E16824009610 was a bit slow using Wheezy a year ago
[22:44:30] <Wolf_> so not really worth it then?
[22:44:44] <CaptHindsight> Wolf_: mostly had issues with getting the cap touch working smoothly
[22:45:15] <CaptHindsight> if you have the time to massage the drivers or of they finally got them working well in Linux
[22:45:21] <CaptHindsight> of/if
[22:46:14] <Wolf_> I was looking at ELO used commercial point of sale touch screens, says linux supported on their site
[22:46:34] <CaptHindsight> they work ok with Touchy, bu then you lose all the nice info and GUI of Axis
[22:47:42] <fenn> you might have to use (gasp) gmoccapy
[22:47:56] <CaptHindsight> http://linuxcnc.org/docs/html/gui/images/touchy.png
[22:48:49] <fenn> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Gmoccapy
[22:49:35] <CaptHindsight> Wolf_: desktop designers seem to be spending more time on screen effects than getting touchscreens working well
[22:50:15] <Wolf_> lol, regular monitor from the wholesale club or amazon it is then
[22:50:51] <fenn> you don't want to spend the next year integrating a tablet interface?
[22:51:33] <CaptHindsight> sheesh, nobody wants to, I wonder why? :)
[22:51:46] <fenn> it would be a great service to the community
[22:53:06] <Wolf_> wow, I can get a 20” led lit monitor on amazon for $80...
[22:53:33] <CaptHindsight> but but but I can make the application window explode into 1M tiny snowflakes and then woosh around the screen, then fall to the bottom while a popup in the shape of a vacuum cleaner sucks them up into the taskbar
[22:53:49] <fenn> i have no idea what you are saying
[22:53:56] <CaptHindsight> that's functionality
[22:54:43] <fenn> tablets have decent GPU and good touchscreens and cost very little, i would use a beagleboard or x86 to do the actual machine control
[23:07:22] <furrywolf> knee mill question: my knee sticks. cleaning and greasing the ways made no change. any ideas?
[23:13:25] <CaptHindsight> leadscrew not to spec?
[23:13:43] <CaptHindsight> bad threads?
[23:14:50] <Wolf_> back the gibs off a touch and see if goes
[23:15:22] <Wolf_> could be worn in from production use...
[23:24:08] <furrywolf> couldn't find gibs. heh.
[23:24:44] <furrywolf> it's not the leadscrew. the machine has no antibacklash on the knee leadscrew, expecting gravity to do the job... it'll pull the screw out and not go down.
[23:24:54] <Wolf_> probably tapered, look for two screws (one top/bottom)
[23:25:41] <furrywolf> yes, that's how the x and y gibs work. I couldn't find any on the knee.
[23:25:59] <furrywolf> the knee it held on by a big wedge-shaped piece. I'm guessing adjusting or shimming it somehow...
[23:50:18] <furrywolf> all the manual says is "taking up the .. knee gibs [is] well understood by the competent maintenance mechanic and [is] not covered in this book."
[23:52:16] <flyback> hey furrywolf how does the solar and battery things go?
