[01:02:27] <zeeshan> CNC BABY!!
[01:02:28] <zeeshan> :D
[01:02:36] <zeeshan> i shoulda made a jig for this
[01:02:40] <zeeshan> customer wants more
[01:03:05] <unfy> grats!
[01:12:12] <jdh> awkward bottle opener?
[01:14:35] <zeeshan> :P
[01:14:40] <jdh> do you have to make that feature around the hole on the other side also?

[01:18:43] <zeeshan> yes
[01:18:48] <zeeshan> the recess
[01:19:17] <pink_vampire> hi
[01:19:17] <jdh> you should make a jig
[01:19:33] <malcom2073> Especailly since they want more
[01:19:37] <Tom_itx> zeesus!
[01:19:44] <jdh> why the complicated facing pattern?
[01:19:50] <Tom_itx> did you make softjaws for P2?
[01:20:14] <Tom_itx> it's just a can opener

[01:26:14] <zeeshan> i just grab on the small flat surface
[01:26:28] <zeeshan> jdh: don't want to do a tool change
[01:26:36] <Tom_itx> hang over the vise?
[01:27:24] <zeeshan> you saw the video!

[01:32:41] -!- md-2 has quit [Ping timeout: 244 seconds]
[01:33:30] <zeeshan> oil mist
[01:33:31] <zeeshan> + air
[01:33:43] <zeeshan> high helix 3 flute cutter
[01:34:01] <zeeshan> it can go 3 times the speed youre seeing but my spindle can only do 3000
[01:34:02] <zeeshan> :(
[01:34:14] <malcom2073> I've only done slow milling thus far
[01:34:18] <malcom2073> I need to get coolant
[01:36:36] <jdh> you need a bolt-on mount for a chinese 24krpm spindle
[01:38:44] <zeeshan> need a new mill :P
[01:39:04] <zeeshan> i can live with this
[01:39:19] <malcom2073> You're moving pretty quick as is
[01:39:33] <jdh> that kinda thing looks pretty good for a tormach
[01:39:41] <zeeshan> ha ha ha
[01:40:46] <zeeshan> malcom2073: https://youtu.be/DehW94gLRKM?t=91
[01:40:49] <zeeshan> it should look like that!
[01:40:49] <zeeshan> :P
[01:40:57] <zeeshan> look at the stream of chips
[01:41:01] <zeeshan> that stuff would hurt :P
[01:41:09] <malcom2073> Is your mill stiff enough for that?
[01:41:14] <zeeshan> yes
[01:41:29] <zeeshan> just doesnt have the spindle
[01:41:40] <zeeshan> if you look at modern mikrons
[01:41:44] <zeeshan> like the dmu 50 or whatever its called

[01:45:51] <unholycrab> anyone have experience cutting with sub-milimeter end mill diameters?

[01:52:59] <unfy> speaking of stiff enough, i knew i forgot something - yet again - at hardware store. been meaning to pick up a small bag of concrete for cheap drill press column

[02:07:30] <unholycrab> im wondering if these end mills are meant for spindle speeds of 80k+
[02:07:43] <gregcnc> unholy crab, small tools are not really any more difficult to use but do need good toolholders with very little runout
[02:07:51] <unholycrab> and the reason im breaking them is because im doing 20k at 8"/minute
[02:08:41] <gregcnc> .0002" per tooth?
[02:09:04] <unholycrab> gregcnc: im trying to figure out how to cut wood without breaking them
[02:09:27] <unholycrab> 2 flute, 0.5mm diameter, 0.079" cut length
[02:09:45] <gregcnc> for frets iirc
[02:09:50] <unholycrab> yea
[02:10:02] <unholycrab> im at a different shop now using nicer cnc machines
[02:10:22] <gregcnc> are chips clearing?
[02:10:43] <unholycrab> not sure. they are so small
[02:11:00] <unholycrab> clearing out of the bits? probably
[02:11:08] <gregcnc> how long before it breaks?
[02:11:39] <unholycrab> one lasted for several passes. then 5 more broke almost instantly
[02:11:46] <unfy> would some air help ? to help clear chips ?
[02:11:57] <unholycrab> im doing that
[02:12:14] <gregcnc> did you check runout?
[02:12:18] <unholycrab> maybe im not using the air well enough
[02:12:21] <unholycrab> whats runout
[02:12:58] <unfy> how much wobble your spindle / mill has. does the hole it cut / groove in material equal 0.5mm ? or is it 0.8mm due to wobble ?
[02:13:31] <unholycrab> i will try to measure that
[02:13:34] <gregcnc> what is the spindle?
[02:14:09] <unholycrab> dont know. says max rpm is 18k
[02:14:28] <unholycrab> but it will spin faster without really getting hoy
[02:14:38] <gregcnc> some kind of router?
[02:16:22] <gregcnc> anyway runout is the place to start, clean to collet, nut, and taper. If using one of those split sleeves to hold the 1/8" tool find a 1/8" collet
[02:16:55] <unholycrab> hard to measure the slot with my caliper. its certainly not more than 0.55mm
[02:17:08] <unholycrab> i can't get a good enough reading to tell what it is
[02:18:29] <unholycrab> gregcnc: the collet looks like this, and fits the shank http://www.techniksusa.com/images2008/CNC%20Router/HSK63F-ER40-web.jpg
[02:22:33] <evil_ren> nice
[02:24:01] <evil_ren> unholycrab: you have to torque down spring collets pretty good to make sure theyre totally clamped and pushed up into the taper
[02:25:13] <evil_ren> besides making sure everything is clean, i have ER16 collet and there is a point where it feels snug, and then i can go maybe 1/8 turn and i can feel it clamping down tight
[02:28:53] <unholycrab> alright
[02:28:56] <unholycrab> so tighten the shit out of it
[02:31:20] <evil_ren> make sure your tool is being held by the entire length of the collet or i guess they deform
[02:32:52] <unholycrab> i insert the tool all the way to where the flute starts
[02:34:29] <unholycrab> i bought new ones on ebay with depth rings though, and it doesn't seem like they go in that far

[04:02:11] <Flipp_> does anyone have experience with the Glacern vises?
[04:04:26] <os1r1s> Flipp_ I have one
[04:04:34] <os1r1s> Haven't used it yet
[04:04:39] <os1r1s> But I have one :)
[04:06:05] <Flipp_> os1r1s: slick. I'm eyeing their 4" vise for my new g0704
[04:06:28] <os1r1s> Flipp_ I have their 5" for my pm25mv
[04:07:06] <Flipp_> ah! cool. how are you liking the pm25?
[04:07:15] <Flipp_> I've heard it's quite similar to the g0704
[04:07:38] <Flipp_> and do you think the 5" is too big for the bed size, or is it fine?
[04:08:06] <os1r1s> Its like a g0704 with a few refinements and better QC
[04:08:28] <os1r1s> 5" is a bit large
[04:08:38] <Flipp_> yup. so far I've been lucky compared to a few reports online from other owners
[04:08:53] <os1r1s> Flipp_ https://www.dropbox.com/s/w0tr13wwrez8cee/millstuff2.jpg?dl=0
[04:08:56] <Flipp_> e.g. mine has the 3-bolt head mod stock, apparently
[04:09:06] <Flipp_> v. nice!
[04:09:20] <os1r1s> Flipp_ https://www.dropbox.com/s/z56jpnmfw16e9cf/millchiptray.jpg?dl=0
[04:09:28] <os1r1s> Thats where I'm at now with the machine
[04:09:44] <Flipp_> slick! did it make any chips pre-cnc conversion?
[04:10:00] <os1r1s> No
[04:10:07] <os1r1s> I ripped it apart as soon as I opened the box
[04:10:08] <Flipp_> I think I'm going to keep mine manual for a while, since we've got a tormach 770 at work
[04:10:26] <Flipp_> haha, good on ya, as did I :)
[04:10:37] <Flipp_> man, that cosmoline gets EVERYWHERE
[04:10:49] <os1r1s> Flipp_ https://www.youtube.com/watch?v=fb_8AnqiKa4
[04:11:11] <os1r1s> Yes, the cosmoline is everywhere
[04:11:24] <Flipp_> wow. is that audio correct? those are super quiet
[04:11:31] <os1r1s> The audio is correct
[04:11:35] <Flipp_> are you following any particular conversion guides?
[04:11:36] <os1r1s> You can't hear it
[04:12:00] <os1r1s> And that was moving pretty quick
[04:12:15] <os1r1s> Flipp_ Not following any real guides. Just winging it
[04:12:29] <Flipp_> cool. ebay ballscrews?
[04:13:19] <os1r1s> Flipp_ The arizonavideo guy
[04:13:24] <os1r1s> Had to make some custom stuff
[04:14:20] <Flipp_> nice, look forward to someday doing the same
[04:14:37] <Flipp_> what are you using to make the cuts/pockets? roughing it out by hand, or using another machine?
[04:15:02] <os1r1s> Flipp_ The mounts/ballscrews were a package
[04:15:26] <os1r1s> I'm just distracted with too many things
[04:15:40] <Flipp_> you didn't have to machine any parts of the mill itself (e.g. slides?
[04:20:02] <os1r1s> No
[04:20:08] <os1r1s> The slides were all good
[04:20:20] <os1r1s> I should have put way oil channels in them, but I did not
[04:29:20] <Flipp_> I'm sure it'll be fine

[09:41:30] <XXCoder> pink_vampire: yeah when engraving parts its basically same
[09:41:34] <XXCoder> machine looks clean lol
[09:41:46] <XXCoder> theres some parts I make that make HUGE mess though
[09:41:56] <XXCoder> like that hose guide nylon part uggh
[09:42:17] <XXCoder> I use snow shovel to clean machine because theres so much crap at end of day
[10:02:05] <enleth> XXCoder: get a construction cleanup vacuum
[10:02:16] <enleth> XXCoder: those will suck in absolutely anything
[10:02:19] <XXCoder> nah not paying for company
[10:02:33] <enleth> ah, ok
[10:02:41] <XXCoder> I wish though
[10:02:47] <XXCoder> nylon mess is sucha big mess
[10:02:53] <XXCoder> shoveling em isnt fun
[10:03:01] <enleth> I had one of those already, it's perfectly happy to suck in a sharp mess of chips and oil
[10:03:09] <XXCoder> most machines has conveyers

[10:18:09] <minibnz> hmmm im not sure if i am a happy little boy or not..
[10:18:09] <minibnz> i ordered 10x tool holders ER16 they are tormach tool clones.. this makes me happy
[10:18:09] <minibnz> i have also ordered 1x ER20 tool holder from tormach with three jacobs chucks.. and the 3/4in MT3 collet... these are yet to arrive.. and makes me sad...
[10:18:09] <minibnz> i also ordered a crap load of collets.. they too have yet to arrive..
[10:18:26] <minibnz> so i has some nice toys i wants to play with but cant..
[10:20:20] <minibnz> the tormach units are set to arrive on friday but i think that will be friday USA time not AU time so they wont arrive until monday :( and god knows then the collets are set to arrive..
[10:22:02] <minibnz> i still have some work to do on the tool pallet i have all my wedges made and the plates to hold them now i gotta make this spin and index ect.. to complete the pallet i need the tool holders from tormach so i can make a universal holder for both these clones and the originals..
[10:24:37] <minibnz> i still have to order 5 more ER20 collet holders and collets before the collection is complete.. thats another $150au.. they are clones..
[10:24:38] <minibnz> so far i have spent $600au on 3 jacobs chucks and 1 ER20 collet and the 3MT collet..
[10:24:38] <minibnz> $200 in the 10x ER16 holder clones another $150 in ER16 collets
[10:24:48] <enleth> minibnz: so you'll be using ER holders as straight shank holders?
[10:25:55] <minibnz> this is the clones i got.
[10:25:56] <minibnz> http://www.ebay.com.au/itm/251213817415?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
[10:26:33] <enleth> what the hell
[10:26:52] <enleth> what kind of taper is that and why is that so cheap?
[10:26:52] <XXCoder> $200 heh
[10:26:56] <XXCoder> mines far cheaper
[10:27:14] <enleth> XXCoder: 10pcs
[10:27:17] <XXCoder> yea
[10:27:23] <minibnz> i will hold these with the 3/4inch 3MT collet in the stock spindle of my X2 mill. will add a new drawbar bolt that has spring washers up top, then a linear actuator that squashes the springs to release these holders from the 3mt collet
[10:27:38] <XXCoder> looks like it attaches to larger size ER or whatever and you can use smaller er16 collets on it
[10:27:39] <enleth> ah, morse
[10:27:45] <minibnz> they are a straight shank that is 3/4' 19mm
[10:28:14] <XXCoder> like on er32 which is big for tiny tools so you add this then small er16 then tool
[10:28:27] <minibnz> i have a 3mt morse taper collet on order from tormach to hold these ER hoders into my mill.
[10:28:58] <minibnz> these are clones of the tormach tooling system..
[10:28:59] <XXCoder> heh I got lucky that er16 fits on my grinder machine
[10:29:06] <XXCoder> so i can use it to cut wood and stuff
[10:29:11] <minibnz> nice
[10:29:12] <XXCoder> *with tools
[10:29:27] <minibnz> always a bonus when you find those sort of matches.
[10:29:31] <XXCoder> I need to figure how to fit larger 53mm so i can use real spindle.
[10:29:53] <XXCoder> I'm currently limited to 43mm which no spindle exist
[10:30:34] <minibnz> so i think i am going to have ended up spending $1000au on 20 tool holders and collets when i am all done.
[10:31:12] <XXCoder> fun
[10:31:14] <minibnz> and the hardware to change them in and out of my mill
[10:31:35] <XXCoder> I got 11 er16 collets for what $21? something lol
[10:31:58] <XXCoder> nice that if I finally get a 53 mm holder I can use spindle with er16 and use em
[10:32:10] <minibnz> i want to order all of what i need/want now but if i do that i will have to really behave and not spend money for the next month :(
[10:35:00] <minibnz> yeah i ordered a set of er16 collets with 13pcs for about the same... but then i also ordered 5each of 2-3mm 3-4 5-6 6-7 9-10mm collets.. so another 25 in total so i can hold the normal tool shanks and still keep one full set aside for whatever.. and i will do the same but 3pcs of each for the ER20 holders, will only have 6 ER20 holders in my set not 10
[10:36:01] <minibnz> so with this i should only have to sort me out some slitting saw arbors and i should be right to stop spending money on the mill and just start using the damn thing to make my parts..
[10:36:14] <XXCoder> lol yeah
[10:36:20] <XXCoder> time for it to earn its keep! ;)
[10:36:56] <minibnz> all up i think i will end up spending total of $4000au on this little beast :)
[10:37:23] <minibnz> not too bad a goal for it to earn back that and then some...
[10:37:57] <minibnz> i might not have white hair before then :)
[10:39:07] -!- skunkworks has quit [Ping timeout: 268 seconds]
[10:39:11] <minibnz> i dont think i could have go the same thing off the shelf for less.. my time is free to me but you i will have to charge :)
[10:42:54] <minibnz> i guess i should allow for the purchase of some more cutters.. at the moment i dont think i can fill the 18 slots in my tool changer with different cutters..
[10:44:24] <XXCoder> I wonder how cheap it is to pay someone to make 54 mm version of my machine holder
[10:45:11] <minibnz> it would just be a bit of lathe work right?
[10:45:24] <XXCoder> nah have to be mill I think
[10:45:47] <XXCoder> I want to keep orginial so I can use grinder for engrave as well as some other uses
[10:46:37] <minibnz> if i was closer to you i would be happy to assist but im way to far awaay to help
[10:46:56] <XXCoder> np though lemme upload to show you what I mean
[10:48:27] <XXCoder> minibnz: http://picpaste.com/thumbs/Screenshot_-_04192016_-_03_47_41_AM-ciJPqhPI.1461062896.png
[10:48:36] <XXCoder> that is my 43mm motor holder
[10:48:51] <minibnz> yeah thats all i thought you were taking about..
[10:48:52] <XXCoder> sadly there is more mount screws on machine Z
[10:49:01] -!- remstw has quit [Quit: quit]
[10:49:08] <XXCoder> 6 total i think
[10:49:11] <XXCoder> this uses only 2
[10:50:42] <_methods> don't you work at a machine shop?
[10:50:50] <minibnz> you said you could make a wood one to make the metal one :)
[10:50:57] <XXCoder> yeah cant use machines though at work
[10:51:11] <XXCoder> minibnz: I'm still uncertain beause of limited height
[10:51:26] <minibnz> sling the guy that runs them at your work a carton of beer or bottl
[10:51:28] <_methods> you don't even have some manual machines for maintenance?
[10:51:38] <XXCoder> and inability to find working CAM lol
[10:51:45] <_methods> wtf you need cam for
[10:51:50] <_methods> that's a simple part
[10:51:53] <XXCoder> _methods: I'm not skilled enough for manual sadly
[10:52:00] <_methods> make it on a manual mill and lathe
[10:52:04] <_methods> oh
[10:52:09] <XXCoder> lathe scares me LOL
[10:52:18] <minibnz> give the guy a pair of DXF's stuck to the carton of beer..
[10:52:20] <XXCoder> I can do button operator and very little past that
[10:52:49] <XXCoder> I do plan to try figure make 54mm one but not right now though
[10:53:16] <_methods> well if you make a 54mm one then you won't need the other one
[10:53:28] <_methods> you just need to make a 43mm sleeve once you build the 50mm one
[10:53:29] <XXCoder> actually I do for grinder
[10:53:32] <_methods> 54mm
[10:53:32] <XXCoder> 27000rpm
[10:53:41] <XXCoder> actually youre right but then meh heh
[10:54:27] <_methods> if you talk to the manual machinists at your work they may let you use the machines during break
[10:54:33] <_methods> and you might learn something to boot
[10:54:59] <_methods> break/lunchtime
[10:55:09] <_methods> you work 2nd or 3rd shift too right?
[10:55:11] <minibnz> looking over one of thess clone tool holders i notice the build quality is pretty nice.. the anodizing is nice and the threads are neat clean and smooth as...
[10:55:36] <XXCoder> 2nd shift. most people dont know how to run manual
[10:55:44] <XXCoder> its VERY rarely used
[10:55:51] <_methods> yeah 2nd shift isn't usually the brightest crew lol
[10:56:01] <XXCoder> in year and 2 months I worked, I ran manual exactly once
[10:56:09] <XXCoder> and that was 2 weeks ago, and simple flat spot at end
[10:56:23] <_methods> well if you get in early and talk nice to the manual guys they may let you use the machines
[10:56:34] <_methods> if they have machines that don't have setups on them
[10:57:05] -!- patrickarlt has quit [Ping timeout: 276 seconds]
[10:57:16] <_methods> and make sure you leave their area cleaner than when you got there and put away all the stuff you use they probably will let you use the stuff again
[10:57:24] <XXCoder> indeed
[10:57:31] <XXCoder> I rather use cnc though
[10:57:39] <_methods> beggars can't be choosers
[10:58:04] <XXCoder> plenty of cnc machines there though its hard to make time
[10:58:22] <_methods> i personally wouldn't use a cnc machine at work if i were you
[10:58:26] <XXCoder> and during day all machines tend to be busy
[10:58:27] <_methods> too many things can go wrong
[10:58:34] <_methods> most of them have setups on them
[10:58:39] <XXCoder> some?
[10:58:47] <XXCoder> even most? heh
[10:58:51] <_methods> and if something breaks on the machine while you're working on it
[10:58:55] <_methods> it will be you getting blamed
[10:58:59] <XXCoder> machine rarely have no setup
[10:59:01] <minibnz> i have access to a nice lathe.. i do the same thing, clean up before leaving and i actually improved the machine by adding a stop switch to the Auto feed to stop the numnuts in the shop busting it again not paying attention..
[11:00:09] <_methods> yeah as long as you clean up they'll usually be glad to let you on the machines
[11:00:10] <minibnz> if they have setups already on it.. see if you can work with thier jigs might be able to profile it here and bore it there. etc..
[11:00:23] <_methods> your next best bet is to take some classes at the local tech college
[11:00:31] <_methods> that way you can use the machines for free
[11:00:33] <_methods> heheh
[11:00:40] <XXCoder> http://picpaste.com/pics/IMG_20160419_035001-Z3b4L3ZG.1461063632.jpg
[11:00:42] <minibnz> go find a maker space.
[11:00:50] <XXCoder> minibnz: tried
[11:00:55] <XXCoder> here its all expensive lol
[11:00:57] <XXCoder> besides
[11:01:09] <_methods> most makerspaces are just full of silly 3d printers
[11:01:12] <XXCoder> I might try make one out of wood on my machine though not too sure how to do side
[11:01:30] <XXCoder> maybe do in 2 parts
[11:01:35] <XXCoder> and use bolts to get em together
[11:01:40] <XXCoder> act as clamp
[11:02:28] <minibnz> hey what about using some already shaped. metal like a C section, all you need to do then is bore two holes and a few others here and there.. then you can make a nicer looking one..
[11:03:16] <XXCoder> heh
[11:03:24] <minibnz> you might even find a box section that the motor fits inside of... bolt that to the axis long enough to make your hoder
[11:03:26] <XXCoder> though I do want one that uses all 6 bolt pattern
[11:03:31] <XXCoder> (fid you see pic?)
[11:03:51] <XXCoder> I'm still puzzled why there is 6 when holder use only 2.
[11:04:34] <minibnz> different heights? like collet vs drill chucks?
[11:04:41] <XXCoder> possible.
[11:04:52] <minibnz> cheap and lazy?
[11:04:53] <XXCoder> though I have never found any true spindle 43 mm size
[11:05:01] <XXCoder> more holes = $ more
[11:05:52] <minibnz> not that much more for a NC machine shop. once you have the first one the next ones are next to free..
[11:07:30] <XXCoder> I guess
[11:07:39] <XXCoder> though I notice that there is bolts on top
[11:07:44] <XXCoder> maybe can remove the Z plate
[11:07:55] <XXCoder> so can swap with larger one thats compitable with 54mm
[11:09:43] <minibnz> maybe
[11:11:25] <enleth> just contacted the Bison Bial factory for their QC30 pricing and availability. Turns out one of their distributors is about 300m from my shop and the local prices are 3-4x lower than export pricing.
[11:11:46] <minibnz> score.....
[11:12:38] <enleth> I can get an ER32 holder for an equivalent of $40
[11:12:44] <enleth> tax included and all
[11:12:57] <enleth> US Shop Tools sells it for over $400
[11:12:59] <enleth> bleh
[11:13:01] <enleth> $100
[11:13:45] <enleth> but I've already seen a few bigger taper holders from Bison that sell for $300-$400 and I could get them for $100 if I needed them
[11:18:42] <enleth> morse taper adapters for MT1, MT2 and MT3 - also $40
[11:20:09] <enleth> shell mill holders - $55-$61
[11:20:11] -!- elhe has quit [Quit: Leaving]
[11:23:11] <enleth> interestingly, weldon shank holders are more expensive than ER32

[14:36:35] <miss0r> I am looking for a good machine vise. Preferably one with a jawspan of 150mm. Can you reccomend one? (I am hoping for a cheap chinese one, that keeps good tolerences)
[14:38:28] <DaViruz> http://granitedevices.com/miniature-servo-drive-ioni/
[14:38:31] <cradek> I bought a 6" kurt-style import and it was adequate (but never great) after taking it apart, measuring all the errors, and machining it flat and square
[14:38:32] <DaViruz> this seems rather interesting
[14:38:45] <cradek> so the second time, I bought a real kurt
[14:39:31] <miss0r> cradek, I'm looking at this one from a local supplyer: https://www.sanistaal.com/da/produkter/staal-og-metaller/suppl-produkter-til-staal/vaerktoej-til-staal/spaantagende/format-spaendevaerktoej/format-maskinskruestikke/format-maskinskruestik-3836/c-466937/2248706/maskinskruestik-mek-125mm.aspx
[14:40:22] <miss0r> "Guaranteed tolerence of 0.02mm"... "For use in machining centers where precision is key"... thoes two does not quite match :)
[14:40:45] <cradek> yes, and tolerance of what
[14:41:09] <_methods> miss0r: i have a couple of the cheap chinese ones and i wouldn't recommend them without rework
[14:41:18] <miss0r> it only says(directly translates): Tolerencearea within 0.02mm
[14:41:41] <_methods> you're probably better off finding auction vises
[14:41:45] <cradek> yes my experience was the vise was not a finished product, just castings that you can finish to work adequately
[14:41:47] <_methods> not sure what a good euro vise brand is
[14:42:08] <_methods> but here in the usa kurt is always decent
[14:42:17] <_methods> and for cnc stuff i like chick or orange
[14:42:29] <miss0r> yesterday I cleaned up a big'ol machine vise with a turning base. It probally weighs in at 80pounds
[14:42:40] <_methods> yeah that's what you want
[14:42:55] <miss0r> but I can't seem to "hammer" the workpeice into contact with the parallel blocks. It is somewhat off
[14:43:08] <_methods> i bought the chinese cnc vises and they're fixed jaws are highly suspect as they come out of the box
[14:43:12] <_methods> mine wobbled all over
[14:43:28] <_methods> and i still don't tighten it too much out of fear of the casting snapping
[14:43:32] <gregcnc> arnold rohm schunk etc..
[14:43:37] <miss0r> hehe. The one I pasted a link to has "downforce" in the jaws. that might come in handy?
[14:44:03] <gregcnc> that's a gerardi or clone
[14:44:12] <_methods> but they do work you just have to pay attention
[14:44:16] <_methods> like most cheap tools
[14:44:28] <_methods> you can get them to do what they're supposed to do with a little extra effort
[14:44:45] <gregcnc> yes basicly all it takes is redesign and rebuild
[14:44:47] <_methods> if you're trying to save some money it's worth a shot
[14:44:49] <miss0r> I just think 2000usd is alot over the top for me at the moment
[14:45:12] <_methods> well you can often find quality vises at auction for decent prices
[14:45:16] <_methods> a fraction of new costs
[14:45:19] <miss0r> if all goes to shit, I can put it in the surface grinder and fix it up a bit
[14:45:31] <gregcnc> you can find new second hand for half new cost
[14:45:48] <miss0r> what you just wrote made no sense to me :S
[14:46:01] <gregcnc> somebody bought and never used

[16:13:48] <CaptHindsight> I've never used that series but I have used the encoder following mode on their other drives
[16:14:56] <skunkworks> pink_vampire, http://www.robotoid.com/appnotes/circuits-quad-encoding.html
[16:15:35] <skunkworks> or I could use one of the ls7184 chips... ;)
[16:16:59] <pink_vampire> http://www.cui.com/product/resource/amt10-v.pdf
[16:17:09] <pink_vampire> like this one?
[16:17:31] <CaptHindsight> also Applied Motion http://www.applied-motion.com/products/series/st-stepper-drives
[16:17:32] <skunkworks> yes - most encoders output quadrature signal
[16:18:22] <pink_vampire> this is the encoders that I'm using on my machine
[16:18:37] <skunkworks> how are those working?
[16:19:08] <skunkworks> they have quite an acceleration lag that some have wondered if it would cause an issue

[16:22:06] <pink_vampire> no
[16:22:16] <CaptHindsight> I saw your pics on the spindle encoder
[16:22:39] <skunkworks> pretty good - got the encoders hooked into the mesa - looks like the counts per inch is 25400 (micron)
[16:22:47] <pink_vampire> but yes it is going to be a kinematic switch.
[16:23:12] <skunkworks> pink_vampire, cool!

[18:33:53] <cradek> the difference between the first and last points make me think you should make a lot more trials
[18:34:36] <JT-Shop> yea the 0.5 point is way off the rest
[18:34:52] <JT-Shop> could be the worn out spindle on the BP maybe
[18:34:55] <cradek> the tip might not be round, the spindle bearings might not be perfect

[19:32:12] <pink_vampire> what is more accurate kinematic switch or strain gauge?
[19:32:34] <andypugh> That depends…
[19:32:40] <pink_vampire> on?
[19:33:29] <andypugh> The interface electronics, largely. To be super-sensitive a strain gauge would need to compensate for temperature and orientation effects, for example.
[19:33:52] <andypugh> A kinematic switch “just works” and plugs straight into a digital IO.
[19:34:29] <andypugh> I don’t know what you percieve as a problem with the 3-bar design. I think it is extremely clever.

[22:46:28] <_methods> starret pretty much is the industry standard for machinist levels
[22:46:40] <_methods> they aren't cheap though typically

[23:04:03] <SpeedEvil> Why do you need better?
[23:04:14] <SpeedEvil> (Not saying you don't)
[23:06:04] <enleth> ever seen a plug and socket pair that would be suitable for making quick-disconnect powertool cables?
[23:06:48] <enleth> I'm getting a little fed up with the dangled pile of shit that inevitably occurs below the powertool rack
[23:07:13] <enleth> and I remember seeing one brand or series of tools that had detachable cables
[23:07:25] <enleth> but they must have used some kind of custom connector
[23:08:40] <enleth> ah, Milwaukee
[23:09:38] <SpeedEvil> microusb
[23:10:01] <enleth> but they obviously don't sell the sockets separately
[23:10:25] <SpeedEvil> This IS almost an ideal case for 3d printing

[23:14:11] <robin_sz> so .. handwheel ...
[23:14:34] <robin_sz> is it possible to limit the speed/step on the axes individually
[23:14:54] <robin_sz> like 50mm a turn on the x1000 setting is great on x and y
[23:15:00] <robin_sz> but way too fast on Z

[23:25:37] <Frank__13> _methods: sorry for the delay, its just that my 98-8 its not enogough, for the hiwin linear rails mounting, its a 2.4mts long axis
[23:25:40] <andypugh> robin_sz: Yes, of course
[23:27:44] <andypugh> each axis has a motion.jog-scale. You probably control those via a mux linked to the selector switch. Just set up a separate mux for the Z axis, controled by the same logic, but with different constants.
[23:28:10] <Frank__13> anyone has any reference about this generic spirit level? thanks :http://www.amazon.com/gp/product/B00KCYZ23Y/ref=s9_simh_gw_g469_i3_r?ie=UTF8&fpl=fresh&pf_rd_m=ATVPDKIKX0DER&pf_rd_s=desktop-1&pf_rd_r=0J6J2MTP366KK3YR1SHW&pf_rd_t=36701&pf_rd_p=2437869742&pf_rd_i=desktop
[23:28:55] <andypugh> Looks a bit like the one I failed to win on eBay this morning
[23:29:30] <Frank__13> lol
[23:30:03] -!- kingarmadillo has quit [Ping timeout: 246 seconds]
[23:30:09] <andypugh> Frank__13: It’s adjustable. So you adjust it until it reads exactly the same way both ways round, and then it is spot-on. There isn’t really much that can be wrong with an adjustable level.
[23:31:04] <andypugh> The one I tried to bid for was nicer and older: http://www.ebay.co.uk/itm/152051143552
[23:31:22] <Frank__13> so why would that be better than my 98-8 (8inch long starret) that's 80 -90 seconds or .005" per foot
[23:31:40] <andypugh> More accurate?
[23:31:59] <andypugh> Like, 10x as sensitive?
[23:32:42] <Frank__13> but even the 300mm starrets have the same graduations
[23:32:52] <Frank__13> but i get what you say
[23:33:38] <andypugh> A precision level has a less-curved vial, so the bubble moves further per second
[23:39:37] <robin_sz> andypugh, I read what you wrote, and its definitely English ...
[23:40:01] <andypugh> Well, I made up the word “controled"

[23:41:06] <andypugh> robin_sz: It’s hard to be copletely specific witout a psychic link to your HAL file.
[23:41:46] <robin_sz> lol, its the standard HB04 chinkyinese handwheel thingy
[23:42:40] <andypugh> Ah, in that case, I have no idea :-) But the HAL almost certainly links to the axis.2.jog-scale HAL pin somewhere.
[23:43:06] -!- os1r1s has quit [Ping timeout: 244 seconds]
[23:44:01] <andypugh> You might want to look at ilowpass while you are messing about scaling jog increments.

[23:46:20] <robin_sz> there is certainly something weird in the config of that jog wheel
[23:46:29] <robin_sz> I found it really jerky
[23:46:37] -!- sliptonic has quit [Ping timeout: 250 seconds]
[23:46:40] <dgarr> robin_sz: if you are using xhc-hb04.tcl, you can probably use the scale opition as described in the README
[23:46:42] <dgarr> http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=blob;f=configs/sim/axis/xhc-hb04/README;h=5565c26bb0863b31ba0ae37ef581ac13eef8a562;hb=HEAD
[23:46:52] <robin_sz> so, I entered some slow accel values in the jogwheel config
[23:46:59] <robin_sz> and that made it nice and smooth
[23:47:06] <robin_sz> so far so good right?
[23:47:10] <dgarr> scales = 1 1 1 1 (optional, plus/minus factors, default: 1 1 1 1)
[23:47:24] <andypugh> robin_sz: Yes, that’s probaly using ilowpass.
[23:47:36] <robin_sz> ah, dgarr, thats what the scales do, right :)

[23:47:51] <andypugh> Yeah, it looks like they scale things :-)
[23:48:11] <robin_sz> dgarr, I did have a straneg thing ... I lowered the accels to make it smoother
[23:48:16] <robin_sz> and it made it smoother
