[00:17:21] <jj1212> just wonder would a 5 axis system with galvo(AB) + gantry (XYZ), if i were to use a CAM software to generate is it a must to look for a CAM software which support to up 5-axis?
[00:21:42] <archivist> jj1212, it greatly depends on what you are making and if you can do some cheating and translation of one axis to another
[00:27:46] <tjtr33> thats 'hostile banana' btw. if any BBB user in here, Darek Malloy has a nic ebook on it (& great youtube tutorials as well )
[00:32:01] <jj1212> hmm... could not quite get the mean of "cheating and translation of one axis to another". I have a small scan area for my galvo, thus I need to use addition movement from gantry to move around my work area for sintering purpose

[03:48:53] <shadowjack> What is the status of s-curve acceleration in linuxcnc?
[04:10:18] <akex2> Hy all
[04:10:51] <akex2> Can i disable a anti gouging protection on linux cnc ?

[05:51:25] <anonimasu> hello
[07:03:40] <jthornton> something reset the usage meter, it was at 9GB the other day and now it is at 1GB!
[07:05:42] <archivist> overflowed?
[07:06:21] <archivist> did it send a carry to the control
[07:27:12] <shadowjack__> Got my chinese frame for 6040 router. Time to start build!
[07:30:12] <malcom2073> Piecing together your own?
[07:40:33] <shadowjack> all stock parts from aliexpress, but not kit
[07:40:43] <shadowjack> kit controllers are crap
[07:41:53] <malcom2073> Yeah that's what I hear
[07:41:59] <malcom2073> Gecko G540 makes for a good replacement :)
[07:42:31] <shadowjack> mechanics are ballscrew
[08:01:59] <jthornton> any docs on the EMBED_TAB_COMMAND on how it works?
[09:10:37] <jdh> my 6040 electronics vastly exceeded expectations.
[09:13:58] <PetefromTn_> morning LinuxCNC
[09:23:22] <malcom2073> jdh: New or old? I've heard the new revisions have gotten better
[09:24:20] <Rab> jdh, jow about the hardware?
[09:24:25] <Rab> er, how
[09:25:26] <malcom2073> jdh: Also, how are your rails? The one I checked out in person, if you put much force on the gantry, the rails had a decent amount of play in them as the bearings stretched out, which is what stopped me from buying one, but his was an early one
[09:25:52] <akex2> Tom_itx: If G61 is for me, don't work ..
[09:27:11] <jdh> newish from carving-cnc
[09:28:19] <jdh> havent noticed any excessive flex. only cut plastics on it though
[09:28:58] <jdh> fix your code to remove the gouging code
[11:09:56] <Tom_itx> JT-Shop, http://linuxcnc.org/docs/html/man/man9/gladevcp.9.html ?

[11:13:18] <skunkworks_> http://www.cnczone.com/forums/linear-and-rotary-motion/257388-software.html
[11:25:37] <PetefromTn_> Hey guys
[11:25:46] <PetefromTn_> quick question for you.
[11:26:09] <PetefromTn_> I am trying to design the ballscrew mounting for the Z axis on the lathe based on what the mounts are etc.
[11:27:12] <PetefromTn_> the driven end of the screw will go thru the pair of angular contacts
[11:27:20] <PetefromTn_> and it is 20mm bore there
[11:27:55] <PetefromTn_> so I need to have a threaded section long enough to have two fine thread nuts that lock each other together locking down the preloaded pair
[11:28:59] <PetefromTn_> I was thinking of going with an M20x 1.5 mm thread there and use two of the thin threaded nuts from mcmaster
[11:29:46] <PetefromTn_> major diameter should be able to fit thru the bearings nice and snug without problems and it would allow me to put a hardened washer against the shoulder
[11:29:57] <PetefromTn_> is there a particular thread that would be better?
[11:32:58] <Connor> That sounds good to me.
[11:34:11] <PetefromTn_> OK
[11:34:26] <PetefromTn_> I am trying to make up a little drawing of the new screw so I can get it ordered here soon
[11:34:38] <PetefromTn_> already got the angular contacts ordered
[11:34:47] <PetefromTn_> removed the old X axis motor last night
[11:35:39] <PetefromTn_> just trying to get this beotch ready for the retrofit here LOL
[11:52:16] <anonimasu> PCW: Hey, are you active and online?
[11:52:27] <anonimasu> PCW: I have a issue with the bldc and 8i20s
[11:52:32] <anonimasu> how would I swap a axis direction >D
[11:53:19] <pcw_home> DRO reads wrong?
[11:53:31] <anonimasu> no it jogs inverse of what I want
[11:53:42] <anonimasu> along with reading inverse
[11:54:42] <anonimasu> I have no clue exactly what I need to swap/change to make it work
[11:54:51] <pcw_home> OK so DRO reads wrong so first thing is fix that
[11:55:39] <pcw_home> (thats actually how to start any servo setup, get the DRO reading right first)
[11:56:00] <anonimasu> yeah, but what settings affects the commutation
[11:56:08] <anonimasu> (after)
[11:56:27] <anonimasu> it commutates perfectly, but the axis goes the wrong dir :)
[11:56:41] <anonimasu> this is with the abs encoders(btw)
[11:57:11] <pcw_home> arent they incremental when running?
[11:57:15] <anonimasu> yeah
[11:57:36] <anonimasu> I can swap A/B to make it go in the other dir(to match(
[11:57:50] <anonimasu> but what after with the bldc scale and output scale?
[11:57:53] <pcw_home> so to get the DRO right you invert the encoder scale
[11:58:26] <pcw_home> to get the commutation right you invert the bldc encoder scale
[11:58:49] <anonimasu> and keep the output scale set where it is?
[11:58:57] <pcw_home> you may neet to invert the PID output not sure
[11:59:07] <pcw_home> (too many coin flips)
[11:59:35] <anonimasu> mhm, that is strange.
[11:59:58] <pcw_home> so a good setup order is DRO,commutation, feedback
[12:00:58] <anonimasu> so it\s a matter of swapping the encoder scale, nothing more
[12:01:06] <anonimasu> and flipping the bldc scale..
[12:01:17] <anonimasu> (and pid)
[12:01:24] <pcw_home> yep
[12:01:27] <anonimasu> tho wouldnt that be the same as to change the output scale?
[12:01:51] <Tom_itx> would it work to swap 2 of the wires on the bldc?
[12:02:19] <pcw_home> no that mucks with the commutation angle
[12:02:29] <anonimasu> then I have to offset the commutation angle
[12:02:32] <anonimasu> :)
[12:02:42] <Tom_itx> k
[12:03:28] <pcw_home> it reverses comutation direction but adds/subtracts 120 degrees (IIKWITA)
[12:03:30] <PetefromTn_> I never messed with bldc motors I always thought they were just DC motors but apparently that is not the case as they have an ac commutation apparently. Interesting
[12:03:57] <pcw_home> they are 3 phase synchonous motors
[12:04:04] <anonimasu> I had a takeoff before.
[12:04:23] <anonimasu> it threw the sled on the x axis off the rails halfway almost into the wall.
[12:04:35] <pcw_home> Takeoff is good, it means commutation is right!
[12:04:40] <anonimasu> more then 40m/min
[12:04:41] <Tom_itx> you can't invert the SCALE on the axis?
[12:05:04] <PetefromTn_> encoder scale negative..
[12:05:13] <pcw_home> yes you can (but scale is just a INI file construct)
[12:06:01] * anonimasu wants a bldc inversion pin
[12:06:02] <pcw_home> it will change the encoder scale negative as pete says which will reverse the commutation direction
[12:06:07] <Tom_itx> heh
[12:06:40] <pcw_home> yeah its over specified so there are too many choices
[12:06:58] <PetefromTn_> sweet my new angular contacts have shipped!
[12:07:17] <PetefromTn_> ya gotta chop down the damn three one swing at a time I always say hehehe
[12:07:22] <Tom_itx> i wonder if chicago got snowed in
[12:07:28] <PetefromTn_> we did
[12:07:29] <pcw_home> I want the spin&win BLDC parameter generator
[12:07:37] <PetefromTn_> LOL
[12:07:37] <Tom_itx> my stuff is stuck there if they did
[12:08:17] <Tom_itx> but that update was 2 days ago so who knows
[12:08:36] <Tom_itx> usps tracking sucks
[12:08:37] <PetefromTn_> right now I am trying to decide if I can get away with stripping and spraying the big sheetmetal pieces on the machine or I need to strip the whole damn thing down
[12:09:01] <anonimasu> PCW: I think I will go and try it when I run to the store later to see if I can get it sorted as soon as possible
[12:09:05] <anonimasu> :)
[12:09:15] <anonimasu> bbl dinnertime
[12:09:21] <pcw_home> is not
[12:09:23] <Tom_itx> anonimasu you been stayin busy?
[12:09:25] <PetefromTn_> dinnertime?
[12:09:42] <anonimasu> Tom_itx: insanely
[12:09:51] <Tom_itx> still at dad's shop?
[12:09:52] <anonimasu> Tom_itx: and I had a new machine day(new old(
[12:09:57] <PetefromTn_> jeez whats that freakin' like ?
[12:10:05] <anonimasu> outgrowing it :S
[12:10:09] <Tom_itx> good
[12:10:18] <anonimasu> maho mh700s
[12:10:24] <roycroft> i don't know if you're like me, petefromtn_, but i would likely strip and shoot the sheetmetal, do the rest of the machine rebuild, and then when it's all done wish i had stripped the whole thing down, and proceed to do that
[12:10:42] <PetefromTn_> heh probably
[12:10:44] <anonimasu> (pallet changer) and horizontal/vertical head and full 4th
[12:10:57] <Tom_itx> you got software to program the 4th?
[12:11:02] <anonimasu> yep
[12:11:04] <PetefromTn_> but the electronics cabinet it pretty large. might just be easier to strip and shoot in place
[12:11:08] <Tom_itx> what are you using?
[12:11:13] <anonimasu> bobcad
[12:11:17] <Tom_itx> ahh
[12:11:30] <anonimasu> I have the basic 4axis since a long time ago I planned ahead
[12:11:55] <anonimasu> its enough for all that I plan on doing
[12:12:01] <Tom_itx> most of what you cut is steel isn't it?
[12:12:24] <anonimasu> aluminium/steel/hard steel/titanium on the way
[12:13:07] <Tom_itx> well, go eat
[12:13:14] <anonimasu> I have a whole shitload of products that I couldnt make before due to half manual machine) that I will run on tombstones now
[12:13:20] <Tom_itx> almost lunchtime here
[12:13:36] <anonimasu> laters!
[12:13:41] <Tom_itx> 2 pallet?
[12:13:44] <anonimasu> yep
[12:13:51] <Tom_itx> we had an okuma with a 2 pallet changer
[12:14:06] <anonimasu> 36 tool mag
[12:14:16] <Tom_itx> it had 90+ iirc
[12:14:20] <Tom_itx> one had 119
[12:14:22] <PetefromTn_> https://www.youtube.com/watch?v=wzL6f_AxQN0 Holy crap that is a neat machine..
[12:14:29] <Tom_itx> on a belt
[12:15:16] <Tom_itx> in a cage behind the machine
[12:15:16] <anonimasu> PetefromTn_: yep
[12:15:32] <anonimasu> :)
[12:15:35] <PetefromTn_> didn't know it was five axis..
[12:15:53] <anonimasu> this one I have is 4 + vertical head too
[12:16:14] <anonimasu> so 4 and 1/2
[12:16:17] <PetefromTn_> does it have that funky mechanized table..
[12:16:27] <anonimasu> no
[12:16:36] <PetefromTn_> OK
[12:16:40] <anonimasu> just a rotary
[12:16:53] <anonimasu> *on the table like that
[12:17:15] <PetefromTn_> what year is it?
[12:17:25] <anonimasu> 1989
[12:17:47] <PetefromTn_> nice where are you located?
[12:17:52] <anonimasu> north sweden
[12:18:03] <Tom_itx> still with that gal from damascus?
[12:18:07] <PetefromTn_> cool go eat lunch man er dinner...
[12:18:09] <anonimasu> yep
[12:18:21] <anonimasu> not from damascus maedonia :D
[12:18:27] <Tom_itx> ahh yeah
[12:18:33] <Tom_itx> short memory
[12:18:40] <anonimasu> same here, anyway lates
[12:18:46] <anonimasu> gotta eat
[12:19:04] <PetefromTn_> amazes me how global this forum is...
[12:19:59] <PetefromTn_> jeez man talk about an origami complex toolchanger system hehe
[12:22:05] <marmite> http://www.ebay.com/itm/171653359607?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT just bougt
[12:22:14] <marmite> anyone have a idea for a pump ?
[12:24:02] <PetefromTn_> there are those venturi blocks if you have a decent compressor?
[12:24:27] <SpeedEvil> Shopvac can get to ~1/3 bar in some cases
[12:27:42] <PetefromTn_> thats pretty cheap unfortunately no US shipping apparently
[12:27:57] <PetefromTn_> I need to just machine one like I have been planning to do
[12:28:11] <_methods> http://www.ebay.com/itm/Vacuum-table-VT2012-CNC-Clamps-Engraving-or-Milling-/281552058255
[12:28:16] <_methods> there ya go
[12:28:19] <_methods> in the usa
[12:28:22] <Rab> SpeedEvil, does it hold up to a long session without airflow?
[12:28:44] <PetefromTn_> too small really
[12:29:16] <PetefromTn_> I have two powerful shop vacs here I wonder how much suction they could provide
[12:29:20] <_methods> i've never actually used one except one that was built into a cnc router at a cabinet shop i worked at
[12:29:21] <marmite> yeah well have found a good table allready^^
[12:29:23] <PetefromTn_> probably not too good for the vac tho.
[12:29:27] <marmite> but a good vacuum pump
[12:29:48] <Vertices> here's a better Maho vid https://www.youtube.com/watch?v=bO7st-UxeY8
[12:29:52] <PetefromTn_> decent vacuum pumps are relatively cheap
[12:30:35] <marmite> yeah problem is i dont really know mutch about vacuum pumps
[12:31:08] <PetefromTn_> dig that crazy toolchanger man...
[12:31:25] <Vertices> it's a little too smart
[12:31:46] <marmite> http://www.ebay.com/itm/Air-or-Vacuum-Pump-for-Wide-Format-Printers-24V-4-4W-US-Fast-Shipping-/300875195632?pt=LH_DefaultDomain_0&hash=item460d8f24f0 i dont know if this could work :D
[12:32:43] <PetefromTn_> no way check out how that vertical head swings away like that COOOL>
[12:32:53] <Tom_itx> PetefromTn_, program that changer for lcnc
[12:33:19] <PetefromTn_> shiiiit I can't even get my damn dog simple umbrella done hehehhe
[12:33:46] <SpeedEvil> Rab: you need to arrange some airflow - there has to be a leak
[12:34:18] <SpeedEvil> Rab: but - in the 'low flow' part of the curve - the aerofoil is mostly stalled, and not drawing much current
[12:35:41] <PetefromTn_> that really is quite an amazing machine
[12:38:23] <Vertices> yeah but I dont trust it
[12:38:45] <Vertices> way too much complexity = way too many failure points
[12:39:45] <PetefromTn_> dunno man it looks pretty damn beefy to me and hey it's german right?
[12:39:56] <Vertices> beefy ok
[12:40:32] <Vertices> i still dont trust rube goldbergy shit
[12:41:00] <Vertices> honestly those tool changes look like they take more time than a dude would
[12:47:54] <PetefromTn_> https://www.youtube.com/watch?v=B5LC8qB49HU hows that for a trunnion table hehe
[12:55:51] <roycroft> so what's the consensus, if there is one, on buying used made in usa jacobs chucks on ebay vs. buying new chinese chucks?
[12:56:20] <roycroft> the drill chuck on my milling machine is starting to cause me grief, and it's a no-name chinese chuck
[12:56:21] <Tom_itx> if it's in good shape i'd get the jacobs
[12:56:34] <roycroft> i doubt disassembling it and cleaning it will do me any good
[12:56:44] <roycroft> a jacobs for a decent price seems like the thing to do
[12:56:58] <roycroft> as long as the rebuild kit for it is still available
[12:57:31] <roycroft> just looking around, i'm seeing 16N chucks going for $60-$75
[12:57:42] <roycroft> and rebuild kits for them are $125-$150
[12:57:50] <roycroft> a brand new chinese made 16N is about $200
[12:58:07] <roycroft> so worst case i would pay slightly more for a us-made one plus the rebuild kit
[12:58:17] <roycroft> and best case i get lucky and the $60 chuck is like new
[13:18:51] <jdh> it is sometimes expensive being cheap
[13:22:32] <zeeshan|2> roycroft: if it worked before
[13:22:35] <zeeshan|2> it might need cleaning
[13:22:40] <zeeshan|2> unless youve got worn jaws
[13:34:13] <MattyMatt> http://www.practicalmachinist.com/vb/general/jacobs-16n-chuck-259383/ it seems you just got to avoid the 2011 ones from the first year of chinese production
[13:39:54] <MattyMatt> PetefromTn_, is that spindle pushing the carousel away on a spring? that saves a motor I guess
[13:42:17] <PetefromTn_> not sure what you are asking..
[13:43:34] <PetefromTn_> I'll tell you what for a CNC lathe that was built in Canada and uses a lot of metric components this thing sure has a TON of 1/4-20 screws on it LOL
[13:44:40] <CaptHindsight> zeeshan|2: feel like running to fedex?
[14:04:19] <_methods> https://www.kickstarter.com/projects/1133560316/black-swift-tiny-wireless-computer
[14:16:38] <zeeshan|2> CaptHindsight: no!
[14:16:42] <zeeshan|2> school mail system will take care of it
[14:16:43] <zeeshan|2> hehe
[14:17:43] <CaptHindsight> guess the storms delayed it
[14:19:01] <jdh> what storms
[14:19:01] <zeeshan|2> https://www.flickr.com/photos/128539016@N05/15762754743/
[14:19:04] <zeeshan|2> trigger wheel came out good
[14:20:00] <CaptHindsight> jdh: http://www.weather.com/storms/winter/video/how-much-snow-did-you-get
[14:34:10] <jdh> I got rained on during last nights bike ride.
[14:34:17] <zeeshan|2> jdh
[14:34:25] <zeeshan|2> that is the sign to start working on the lathe!
[14:34:28] <jdh> but, it was still 50f
[14:35:03] <_methods> https://play.google.com/store/apps/details?id=ly.mens.checkyourprivilege
[14:37:11] <_methods> zeeshan|2: where'd you get the ajxu?
[14:37:45] <zeeshan|2> ajxu?
[14:38:03] <_methods> yes that cutter in your flickr feed
[14:38:08] <_methods> the mitsubishi ajxu
[14:38:21] <zeeshan|2> it came with a big lot of tools i bought
[14:38:24] <_methods> damn
[14:38:28] <_methods> well you scored there
[14:38:34] <_methods> that is one bad ass cutter
[14:38:59] <zeeshan|2> ive honestly only used it in cast iron
[14:39:02] <zeeshan|2> it was okay on the bridgeport
[14:39:12] <_methods> wtf you used in the bridgeport
[14:39:15] <zeeshan|2> haha
[14:39:22] <_methods> did you even look at teh feeds and speeds for that
[14:39:34] <_methods> you might want to take a look at that lol
[14:39:36] <zeeshan|2> no
[14:39:44] <_methods> yeah well that's not a normal cutter man
[14:40:07] <zeeshan|2> know some values of the top of your head?
[14:40:08] <zeeshan|2> for like steel?
[14:40:34] <_methods> not off the top of my head you really need to look them up
[14:40:42] <_methods> http://www.mitsubishicarbide.com/mmc/en/product/pdf/b/b028g.pdf
[14:41:30] <_methods> the insert you have on there will determine your correct feeds and speeds
[14:43:46] <_methods> with the fh7020 insert looks like in cast iron you need to be cutting with about 150m/min
[14:43:47] <zeeshan|2> looks like its a type P
[14:44:00] <zeeshan|2> so wrong insert to begin with for cast iron
[14:44:01] <zeeshan|2> haha
[14:44:06] <_methods> yeah
[14:44:15] <_methods> it will work for both i think
[14:44:30] <_methods> the fh7020 grade
[14:45:36] <_methods> hehe your bridgeport can't rapid fast enough for that thing
[14:46:01] <zeeshan|2> i wish tehse guys would tell me the cutting edge radius
[14:46:16] <zeeshan|2> cause then you can figure out what the minimum feed rate you need so you dont plough
[14:46:36] <_methods> on what?
[14:46:44] <_methods> it should be on every insert box
[14:46:51] <PetefromTn_> hey any of you guys familiar with the Heidenhain 151 control?
[14:47:05] <zeeshan|2> PetefromTn_: thats what i had
[14:47:18] <PetefromTn_> on what?
[14:47:29] <zeeshan|2> _methods it looks like theyre recommending 1.4mm doc (.050~)
[14:47:42] <zeeshan|2> i vaguely remember it wasnt happy at 100 though doc
[14:47:46] <zeeshan|2> but at 60 ish it was okay
[14:48:15] <zeeshan|2> hm that cant be right
[14:48:22] <zeeshan|2> theyre saying .059 in/tooth
[14:48:23] <zeeshan|2> lol
[14:49:00] <zeeshan|2> 70.8 ipm
[14:49:02] <zeeshan|2> ..!!
[14:49:08] <zeeshan|2> yea i was not running anywhere close to that
[14:49:12] <zeeshan|2> PetefromTn_: on the mill
[14:49:52] <zeeshan|2> okay i found the values for cutting edge radius.
[14:49:55] <zeeshan|2> it is .059"
[14:50:09] <zeeshan|2> shit, so if you go slower than 70 ipm on steel
[14:50:13] <zeeshan|2> you're pretty much ploughing
[14:51:18] <PetefromTn_> I have a friend who has asked me to work a bit in ANOTHER shop that has a bridgeport interact 1 with that control on it and I don't know anything about it.
[14:51:40] <zeeshan|2> it uses conversational programming
[14:52:04] <PetefromTn_> only?
[14:52:12] <zeeshan|2> yea
[14:52:17] <PetefromTn_> shit
[14:52:32] <zeeshan|2> you can learn it
[14:52:34] <zeeshan|2> im sure its not hard
[14:52:42] <PetefromTn_> do you know how to program fixture offsets in it?
[14:52:49] <zeeshan|2> no , sorry
[14:52:49] <zeeshan|2> http://content.heidenhain.de/doku/oma_controls/CD1/tnc/151_155a/gb/22504124.pdf
[14:53:09] <zeeshan|2> its 316 pages
[14:53:14] <zeeshan|2> but it looks like its mostly pictures lol
[14:53:37] <PetefromTn_> thx
[14:53:49] <zeeshan|2> they have examples
[14:53:50] <zeeshan|2> but theyre in german
[14:53:54] <zeeshan|2> http://content.heidenhain.de/doku/oma_controls/dvd_oma_html/de/index/N12DA1/N12E50/N13C2A/N13C2A.html
[14:56:09] <Connor> zeeshan|2: Did you buy a manual mill with power feed ?
[14:56:17] <zeeshan|2> i did
[14:56:19] <zeeshan|2> but its sold
[14:56:26] <Connor> You sold it ?
[14:56:27] <zeeshan|2> it was a column mill pos
[14:56:30] <zeeshan|2> er
[14:56:33] <zeeshan|2> round column mill
[14:56:45] <Connor> Why did you buy it ?
[14:56:50] <zeeshan|2> it was cheap
[14:57:03] <zeeshan|2> i got it for 200 bux ( i forget exact number)
[14:57:05] <Connor> you make any money on selling it ?
[14:57:07] <zeeshan|2> and i sold it for 1400
[14:57:18] <Connor> Damn, you did good.
[14:57:34] <Connor> Why in the heck did they sell it for 200?
[14:57:35] <zeeshan|2> the guy wanted something small, if he bought it brand new itd cost me 3000+tax
[14:57:46] <zeeshan|2> Connor: floor space per month was too much
[14:57:52] <zeeshan|2> im still bitter i couldnt pick up that monarch lathe
[14:57:58] <zeeshan|2> he wanted 300 for that huge lathe.
[14:58:09] <zeeshan|2> and there was an edm for 700
[14:58:11] <zeeshan|2> sodick
[14:58:19] <zeeshan|2> er 800
[14:58:25] <zeeshan|2> o well
[14:58:40] <PetefromTn_> thats funny you hated that milll and art and I liked ours...
[14:58:51] <zeeshan|2> PetefromTn_: i only needed to try it once to hate it
[14:58:52] <zeeshan|2> lol
[14:58:56] <zeeshan|2> coming from the bridgeport clone
[14:58:59] <zeeshan|2> i can hope you can see why
[14:59:11] <PetefromTn_> honestly I hated my bridgeport clone sold it.
[14:59:19] <zeeshan|2> you cant even compare the two man
[14:59:25] <zeeshan|2> the bridgeport clone is a real mill
[14:59:29] <zeeshan|2> this thing was a toy
[14:59:37] <PetefromTn_> its just a bench mill man
[14:59:41] <zeeshan|2> exactly
[14:59:47] <zeeshan|2> for that same price
[14:59:50] <zeeshan|2> i'd pick up a rf45
[15:00:00] <PetefromTn_> you would probably hate that too.
[15:03:07] <PetefromTn_> man that heidenhain looks old school
[15:03:26] <PetefromTn_> and I don't mean the GOOD old school hehe
[15:16:13] <_methods> well you scored with that cutter zeeshan|2 once you get your cnc running you'll be able to use it to it's full capabilities
[15:16:21] <_methods> that thing is a hog
[15:16:32] <_methods> very shallow DOC but high feedrate
[15:16:53] <_methods> my favorite rougher by far and the inserts last forever
[15:17:09] <zeeshan|2> :D
[15:17:16] <zeeshan|2> thanks for forcing me to read about it
[15:17:21] <zeeshan|2> i didnt realize it needed such a high feed rate
[15:17:27] <_methods> yes scary fast
[15:17:36] <_methods> it's a blast watching them do their thing
[15:17:41] <anonimasu> PetefromTn_: yeah it\s a very complex toolchanger
[15:17:44] <_methods> you'll want a chip deflector lol
[15:18:37] <_methods> i hear the tungalloy high feed cutter will outrun the ajxu though
[15:18:44] <_methods> but either way they are very close
[15:19:01] <anonimasu> PetefromTn_: tho, they dont mess alot apparently only that they refuse to fold the arm inside if there are chips stuck
[15:19:12] <anonimasu> mhm, heidenhain is not bad(only the low range)
[15:19:26] <anonimasu> 310 110 controls, the 3xx controls are very neat
[15:19:49] <anonimasu> I find it funny that the control on the maho does 3d contouring and everything at fast enough speed for me
[15:20:15] <PetefromTn_> anonimasu nice sounds like a good machine.
[15:20:24] <anonimasu> and has more memory then the tnc 310 on the other milling machine
[15:20:45] <PetefromTn_> trying to figure out if I want to try to learn this damn heidenhain control for a side job working at another local shop or not..
[15:20:53] <_methods> http://www.zdnet.com/article/critical-linux-security-hole-found/
[15:20:56] <anonimasu> PetefromTn_: they are very very easy compared to fanuc
[15:21:05] <PetefromTn_> which is?
[15:21:09] <anonimasu> fanuc,?
[15:21:22] <anonimasu> the standard controls :D
[15:21:49] <anonimasu> the heidenhain conversational language is very very easy and neat to learn
[15:21:51] <PetefromTn_> the heidenhain 151 control is conversational. I have not really played with much conversational everything so far for me has been hand coded or G code from CAM
[15:22:15] <PetefromTn_> thats good to hear..
[15:22:24] <anonimasu> pretty much a circle looks like this
[15:22:29] <anonimasu> CC x0 y0
[15:22:30] <PetefromTn_> the owner of the shop is apparently the only one who knows how to operate it LOL
[15:22:44] <_methods> http://www.openwall.com/lists/oss-security/2015/01/27/9
[15:22:58] <_methods> just so you know ^^
[15:23:46] <anonimasu> LP PR30 PA0 RR F100 (feed to perimetr of circle with right side cutter comp)
[15:23:55] <anonimasu> at 0 degrees start
[15:24:53] <anonimasu> and CP IPA1080 IZ-10.0 F600
[15:24:54] <PetefromTn_> oh hell..
[15:25:01] <anonimasu> for a helical circle
[15:25:05] <anonimasu> err move
[15:25:20] <anonimasu> (I have a post that does 3d arcs for the heidenhain)
[15:25:40] <anonimasu> so it works ok for contouring
[15:25:43] <PetefromTn_> not even sure if it will take it..
[15:26:01] <anonimasu> for the maho, (which does full arcs in any plane)
[15:26:18] <PetefromTn_> Sweet just got a shipping confirmation for my new 7.5HP lathe spindle motor...
[15:26:32] <anonimasu> with no plane selection before the arc.. (I had a hard time to get it sorted)
[15:27:22] <PetefromTn_> I have had a hard enough time just getting used to linuxCNC and the HAAS controls we have been using at work as well as their automatic probing routines.
[15:28:18] <PetefromTn_> maybe I should just stick to my own stuff and the place I work part time currently and let someone else worry about that bridgeport with Heidenhain 151 ;)
[15:28:49] <anonimasu> I think i agree..
[15:29:07] <PetefromTn_> LOL yeah why?
[15:30:11] <anonimasu> if it's the 1.5d control that I think about,
[15:30:14] <zeeshan|2> if they pay you good
[15:30:17] <zeeshan|2> id learn it :)
[15:30:54] <PetefromTn_> no idea yet what they are offering just heard about it this morning
[15:31:04] <anonimasu> well dosent hurt to listen
[15:31:26] <PetefromTn_> but my friend works there and he knows about what I need to get so I doubt he would have bothered me with it if they were wanting someone for cheapass prices
[15:31:48] <PetefromTn_> but ya never know!
[15:32:41] <anonimasu> the half manual machines are meant to be stayed away from too.
[15:34:17] <anonimasu> you will die changing tools :D
[15:34:40] <anonimasu> I had 6 tols on a small part that I made a run of before for my own needs :S
[15:34:51] <anonimasu> some had a 30 sec cycletime
[15:35:12] <anonimasu> the part took 8 minutes
[15:35:41] <PetefromTn_> Oh I am with you there man so far I am STILL changing tools manually on my Cincinatti since I have not gotten the orient working for toolchange yet.
[15:36:05] <PetefromTn_> http://www.ebay.com/itm/UPDATED-5-5KW-7-6HP-25A-220V-VFD-VARIABLE-FREQUENCY-DRIVE-INVERTER-/251033270542?pt=LH_DefaultDomain_0&hash=item3a72bfb90e does this look like a 7.5hp single phase input capable VFD>
[15:36:09] <anonimasu> big part for getting this machine(and the price was too good to pass)
[15:36:23] <anonimasu> 5k eur
[15:36:42] <anonimasu> (I knew the people that were selling it
[15:36:46] <PetefromTn_> you only paid 5k for that maho?
[15:36:48] <anonimasu> yeah
[15:36:54] <PetefromTn_> damn I thought I got a steal
[15:37:00] <anonimasu> same machine in germany was 35k eur
[15:37:08] <PetefromTn_> was it a working complete machine?
[15:37:11] <zeeshan|2> pete
[15:37:12] <anonimasu> yes
[15:37:14] <zeeshan|2> it says 1 or 3 phase input
[15:37:16] <PetefromTn_> nice
[15:37:16] <zeeshan|2> interesting
[15:37:22] <PetefromTn_> yeah I know right
[15:37:22] <zeeshan|2> damn chinese :D
[15:37:23] <anonimasu> they even serviced it before I got it
[15:37:24] <PetefromTn_> hard to believe
[15:38:00] <anonimasu> (this is from a service company for nc machines) as they wouldnt sell it as working with any problems)
[15:38:13] <PetefromTn_> nice
[15:39:23] <anonimasu> pride of their work I guess(I am having them help me get the tool measurement set up on the lathe and adjusting it since they fixed me up with this) and since they spent time fixing that problem before they sent it
[15:39:44] <PetefromTn_> what lathe?
[15:39:54] <anonimasu> mondialle gallic 420
[15:40:02] <anonimasu> err mondiale gallic
[15:40:13] <anonimasu> 700 eur :D
[15:40:23] <rob_h> evning all
[15:40:41] <anonimasu> arrived with dead control
[15:40:57] <PetefromTn_> hey rob_h
[15:41:02] <anonimasu> that's how I met the people I bought this from they read out the paper tapes with parameters for me
[15:41:16] <PetefromTn_> sounds like you lucked out man.
[15:41:27] <PetefromTn_> do you have work for the machine?
[15:41:31] <anonimasu> I plan to part with it tho
[15:41:40] <anonimasu> more then I want
[15:41:47] <PetefromTn_> damn thats nice
[15:41:53] <PetefromTn_> that is what I am after
[15:42:05] <PetefromTn_> hard to find good paying work around this place it seems
[15:42:08] <anonimasu> I am getting set up for running unattended)
[15:42:30] <rob_h> can never have too many machines i say :)
[15:42:52] <zeeshan|2> machine hoarder!
[15:42:53] <zeeshan|2> :-)
[15:43:08] <anonimasu> so I can have limited production and, also do my regular stuff that is constructing stuff
[15:43:37] <PetefromTn_> I'm struggling to just get a CNC mill and CNC lathe working here.
[15:43:53] <anonimasu> PetefromTn_: I am struggling with a plasma retrofit to emc
[15:44:22] <PetefromTn_> nice
[15:44:24] <rob_h> i wanna retro a turret punch some time think that be a nice project
[15:44:26] <anonimasu> dont give up :) and finish it _completely_ dont leave it on half
[15:44:28] <PetefromTn_> well these guys can sure help
[15:44:50] <PetefromTn_> Oh I don't intend to give up
[15:44:53] <anonimasu> it's the biggest mess to have a half togther machine and then you need something you didnt before when you actually want/need to use it
[15:45:05] <anonimasu> drives me insane
[15:45:10] <PetefromTn_> but its a bitch getting the programming side of this going as I am NO programmer...
[15:45:32] <anonimasu> haha, linuxcnc is _special_ to say the least :)
[15:45:58] <PetefromTn_> yeah what I have working of it so far works great tho
[15:46:25] <anonimasu> the lathe tool forever before I had it sorted, as the factory parameters werent very good
[15:46:29] <anonimasu> took
[15:46:33] <PetefromTn_> just need to get a little bit more done on the Cincinatti and I can hopefully change tools and at the same time I will be doing the retrofit on the lathe too.
[15:47:16] <rob_h> hows that going pete did u get any where changing it back
[15:47:37] <anonimasu> the programming FAPT (not bad) if I had to work on a lther I'd like to have that for programming(the acronym is for Fantastic Amazing Programming Tool) :D
[15:47:39] <PetefromTn_> on the one hand I wish I had cash to pay someone to come in here and get it all finished but on the other hand if it freakin' breaks and someone else did it I won't know how to fix it..
[15:48:15] <PetefromTn_> rob_h no not so far man. we tried to see it working with halscope and PCW thought the delay was too much
[15:48:47] <PetefromTn_> now I am thinking I should just go back to the analog control lines and work thru getting the thing reset for that and try the PID loop control
[15:49:24] <PetefromTn_> but PCW said he thought I should try the DC braking setup and just roll the spindle around from an index pulse and stop it on an encoder count at the orient position and brake.
[15:49:31] <PetefromTn_> not sure what the hell to do really...
[15:49:57] <PCW> I woudl try the brake first since its a lot less invasive
[15:50:40] <PetefromTn_> yeah I know but I am kinda dubious about the part that it says it is not designed for prolonged use
[15:50:58] <PetefromTn_> the manual seems to indicate that it is more for quickly slowing the spindle down
[15:51:05] <rob_h> becasue injects the motor but ur motor is a real spindle motor yea
[15:51:09] <rob_h> fan cooled etc
[15:51:29] <PCW> Wel its not used in a prolonged manner
[15:51:29] <PetefromTn_> yeah it is a real spindle motor with seperate electric fan...
[15:51:50] <rob_h> be fine only takes what 1 sec pocket to pocket
[15:51:55] <PetefromTn_> I feel a bit more confident with doing the PID loop and analog control really
[15:51:57] <PCW> yeah I don see tha DC would be any worse than normal load
[15:52:37] <PetefromTn_> we had it working before with analog control setup and it worked fine until I insisted on switching it to Modbus
[15:52:42] <jack16> It depends on current (amps)
[15:52:43] <rob_h> i know the motors take next to zero amps to spin at 6k+ as they are super fine balanced
[15:53:02] <PetefromTn_> this motor is not your typical spindle motor
[15:53:07] <PCW> VFDs are usually pretty lousy servos
[15:53:10] <PetefromTn_> it spind up to 12k at top speed
[15:53:30] <PetefromTn_> it drives the spindle via a 2-1 ratio timing belt drive.
[15:53:36] <rob_h> whos motor did they fit on them? was it CT?
[15:53:48] <PetefromTn_> yeah I THINK it is a CT control motor.
[15:54:01] <PetefromTn_> it is a big huge tall square profile motor
[15:54:12] <rob_h> yea just like a fanuc or mitshi etc
[15:54:17] <PetefromTn_> heavy as hell just put brand new spindle motor bearings in it..
[15:54:30] <anonimasu> PetefromTn_: I have a testpart drawn up for then I get time :D http://ah.io23.net/ul/files/testpart.png
[15:54:50] <PCW> so 25% dc injection shoud be no worse than 25% spindle load (and should be plenty)
[15:55:15] <rob_h> what is it, 40/45amp motor?
[15:55:20] <PetefromTn_> I don't know jack about the motor all I know is it is quite expensive to replace..
[15:55:29] <PetefromTn_> 7.6kw
[15:55:40] <PetefromTn_> don't remember the amperage
[15:55:48] <rob_h> 7.5kw 30min 5.5kw const?
[15:59:49] <PetefromTn_> I can't remember trying to get a picture of the damn label
[16:00:36] <rob_h> prob like ours hidden by the drawbar ram
[16:01:14] <PetefromTn_> yeah it is down low in that mess
[16:03:27] <Deejay> gn8
[16:07:15] <zeeshan|2> rob_h: sorry if youve already answered this before, but how are you indexing your spindle?
[16:07:20] <zeeshan|2> on your machines
[16:07:59] <zeeshan|2> bobo!
[16:08:10] <bobo_> hi
[16:08:49] <bobo_> saw your new machine movie
[16:08:56] <PetefromTn_> http://i.imgur.com/qgZf6lh.jpg best pic I could get jammin' my cellphone in there heh
[16:09:47] <anonimasu> who's?
[16:09:57] <zeeshan|2> bobo_: the marker? :)
[16:10:19] <bobo_> marker
[16:10:28] <zeeshan|2> hey, you were asking me a while back
[16:10:34] <zeeshan|2> about those two dimples in the casting
[16:10:39] <zeeshan|2> on the left side of the machine in the base
[16:11:12] <bobo_> and
[16:11:18] <zeeshan|2> what are they for
[16:11:42] <zeeshan|2> i noticed there is a metal tube that goes from the ball screw (Z axis)
[16:11:46] <zeeshan|2> and seems to dump fluid.
[16:11:50] <zeeshan|2> lemme see if i can find a pic.
[16:11:58] <rob_h> back
[16:12:36] <rob_h> zeeshan|2, i did try with standard VFD in closed vector but was abit hit and miss... it woked but not grate..used PID from linuxcnc
[16:13:00] <bobo_> refresh my memory on dimples
[16:13:17] <rob_h> then afew years back i swicked it out for a new Yaskawa VFD A1000
[16:13:45] <bobo_> my cat wants out
[16:13:49] <rob_h> running in closed vector mode too but has spindle orienation built in so just fire it and wait for finish
[16:14:20] <rob_h> the yaskawa also has there build in CNC spindle software.. what it does other than add afew functions like spindle orienation i dont know
[16:14:44] <zeeshan|2> by hit and miss
[16:14:46] <zeeshan|2> what do you mean exactly
[16:14:47] <PetefromTn_> http://www.ebay.com/itm/1pc-Yaskawa-A1000-7-5KW-5-5KW-380V-CIMR-AB4A0018FAA-xhg07-/301506687822?pt=LH_DefaultDomain_0&hash=item463332f34e
[16:15:37] <rob_h> hit and miss as in took awhile to setting... and you had to spin it before you could PIDit, to build up motor flux etc
[16:15:39] <zeeshan|2> bobo_: https://www.flickr.com/photos/128539016@N05/15761132814/
[16:15:47] <rob_h> the yaskawa is much better can position it from a stop
[16:16:32] <PetefromTn_> is your spindle direct drive?
[16:16:38] <rob_h> alot of the time i just Spindle orient from full speed so spindle stops at position read for tool change on the way up in the Z move
[16:16:45] <rob_h> no its belt 1:1
[16:16:59] <rob_h> its a mitsubishi motor, 8k rpm, 37amp 200v
[16:17:57] <zeeshan|2> im trying to find a solution for my lathe
[16:17:58] <zeeshan|2> :/
[16:18:19] <zeeshan|2> i might just end up adding an electrogmagnetic brake
[16:18:23] <PetefromTn_> do you think the 2-1 ratio of the belt drive on my machine would help that?
[16:18:41] <rob_h> solution for what?
[16:18:50] <zeeshan|2> to hold the spindle in place
[16:18:53] <zeeshan|2> while i drill holes
[16:18:56] <zeeshan|2> w/ a live tool
[16:19:01] <rob_h> yea you deff need a brake or pin lock
[16:19:38] <rob_h> unless like the more current lathes they hold with the spindle motor if built in, but thats more a high speed servo than anything
[16:19:52] <zeeshan|2> well thats another option
[16:19:55] <zeeshan|2> just get rid of the motor
[16:19:58] <rob_h> i know some laths have a servo they clutch in and out
[16:19:58] <zeeshan|2> and throw a servo in there
[16:20:09] <PetefromTn_> that is what my lathe came with unfortunately it is not there anymore..
[16:20:27] <rob_h> yea but how many Nm do you need ,.. i mean our lathes are 18kw etc thats a big servo
[16:20:35] <zeeshan|2> only 2.2
[16:20:41] <zeeshan|2> kW
[16:20:54] <zeeshan|2> @ 1800 rpm
[16:21:18] <rob_h> fairly easy just change the belts if you have to and pullys as a need good drive
[16:21:39] <rob_h> i mean our little sliding head has indexing, that index's the motor then puts a pin in place and u can power tool.
[16:21:40] <zeeshan|2> i bet i can pay for it by selling the vfd + motor
[16:21:54] <zeeshan|2> its going to need a pretty big servo drive though
[16:22:03] <rob_h> the same on our 4 axis powerd lathe .. that has a DC spindle motor
[16:22:36] <PetefromTn_> rob_h did you see the pic I posted of my motor's plate?
[16:24:14] <rob_h> o nice they gave u the base speed
[16:24:43] <PetefromTn_> yeah it sure is an oddball motor specs
[16:24:57] <rob_h> ours dont give u that nice bit of info
[16:25:28] <PetefromTn_> I had help getting the VFD settings correct from Mike on the zone who knows a lot about this stuff.
[16:25:57] <PetefromTn_> but he has not messed with what I am doing here with the orient on my hitachi
[16:26:26] <rob_h> yea iv seen his posts before grate bit of info he put out there
[16:26:47] <zeeshan|2> i think i will try pcw's idea first
[16:26:57] <PetefromTn_> the video you posted showing the VFD positioning looked pretty damn good to me man I know you were not happy with it but I have to wonder if it was 2-1 if it would be easier on the spindle to hold position etc.
[16:27:03] <zeeshan|2> use dc injection to stop the vfd in place
[16:27:08] <zeeshan|2> then i will engage brake
[16:27:17] <zeeshan|2> too bad its open loop :P
[16:28:14] <PetefromTn_> at even very slow speeds this motor has a shitload of torque it seems from the little tapping I have done etc.
[16:28:15] <rob_h> the VFD also did not give the motor the power it should have i found like when face milling etc , was easy to load up
[16:28:42] <rob_h> now i can facemill no problem again
[16:28:49] <PetefromTn_> what was the KW rating of that motor
[16:29:05] <rob_h> cant drill 1" holes like i can on the other VMC lol but that does have a gear box
[16:29:20] <rob_h> same as yours, 5.5 const, 7.5 30min
[16:29:25] <zeeshan|2> hm
[16:29:27] <PetefromTn_> I run a flycutter and it seems to cut whatever I need without issue even kinda deep...
[16:29:36] <PetefromTn_> in steel etc?
[16:29:40] <rob_h> ye
[16:29:43] <zeeshan|2> do you guys know why drilling requires so much force?
[16:29:54] <zeeshan|2> i learned this the other day in class lol
[16:30:04] <PetefromTn_> I have drilled a bunch of 1" plus holes in steel on the machine before without issues..
[16:30:17] <rob_h> if back up off the feed yea its fine
[16:30:34] <rob_h> but i mean drill holes not play with it ;)
[16:30:40] <zeeshan|2> rofl
[16:30:46] <PetefromTn_> I was not playing with it believe me..
[16:30:56] <zeeshan|2> ive drilled a 2" hole
[16:31:03] <zeeshan|2> for my steam engine on the school lathe which is 7.5HP
[16:31:16] <zeeshan|2> i think i was turning at 50 rpm
[16:31:27] <zeeshan|2> it had no issues :P
[16:31:53] <PetefromTn_> well whatever the case it seemed like despite the lack of power you had the orient worked for a good while for you like that right>
[16:32:01] <rob_h> on manual lathe turning the handle takes abit
[16:32:18] <rob_h> yea sure it did i think ull be more than happy
[16:32:40] <zeeshan|2> so for a 3/8 drill bit
[16:32:50] <zeeshan|2> tests showed that due to the stationary point @ the middle of the drill bit
[16:33:00] <zeeshan|2> (which causes it to extrude the material, not cut)
[16:33:13] <zeeshan|2> 40-60% of power is consumed by that extrusion
[16:33:28] <PetefromTn_> I really think I should at least try to do the analog control spindle orient I can always add the braking setup if it does not work..
[16:34:32] <rob_h> PID can take abit to setup... while braking is just switch it on and off
[16:34:48] <bobo_> zeeshan: my guess is your mill is using 2 connected tanks to seperate cutting fluid from drained lub oil ? maho only has seperate sheet metal tank --cutting fluid return by hose---drained lub and leaked cutting fluid drain from machine base into sheet metal cutting fluid tank tank
[16:35:12] <zeeshan|2> bobo_: okay
[16:35:15] <zeeshan|2> so its a lube catch tank
[16:35:30] <zeeshan|2> coolant take is seperate for mikron too
[16:35:41] <zeeshan|2> which i unfornately dont have :(
[16:36:02] <bobo_> bucket
[16:37:04] <rob_h> pete dont forget as u have a 2:1 spindle u double ur torque right away over us
[16:37:21] <rob_h> its a shame u dont have a 1:1 pully on there also so you can swop it over to 12k
[16:37:30] <rob_h> be nice for alli jobs etc then
[16:38:03] <rob_h> one of our machins came to us at 4k... took the cover off and it had the pully in there for 1:1 and gave us 6k then
[16:38:15] <PetefromTn_> yeah that is what I am wondering... I would love to have 12k but really all the parts I make are aluminum mostly and I just use more flutes and feed deeper works fine...
[16:38:33] <PetefromTn_> this is just one pulley range...
[16:38:35] <zeeshan|2> wut
[16:38:55] <zeeshan|2> you dont want higher speds for al?
[16:39:01] <PetefromTn_> and we have already masked the second spindle index pulse so I don't want to change it really
[16:39:02] <rob_h> yea our next VMC has to be 10k spindle and random changer etc
[16:39:42] <zeeshan|2> CAD challenge for the day, make it in the least number of steps: http://i.imgur.com/5Qg2tTp.png ; http://i.imgur.com/X9iCXXk.png
[16:39:42] <PetefromTn_> sure would be nice but I don't feel like chaning out spindle bearings all the time either. The machine goes thru aluminum pretty quick and I am being gentle really with it mostly.
[16:40:05] <rob_h> yea bearings was a problem on the early machines i know
[16:40:42] <PetefromTn_> yeah this is a 1997 machine
[16:41:15] <rob_h> plus some earaly 12k machiens where realy bad on HP a friend had one and he always moaned about it
[16:41:45] <PetefromTn_> honestly if I could get the damn toolchanger working I would be quite pleased with the machine overall. 6k is not bad really and it has enough torque to cut steels with ease
[16:42:16] <PCW> "PID can take abit to setup... while braking is just switch it on and off"
[16:42:17] <PCW> That was my point, adding the bit in hal to brake and reprogramming the
[16:42:19] <PCW> VFD to have a brake input dont affect operation of your machine
[16:42:20] <PCW> and can be left there even if you change to PID loop orient
[16:42:40] <zeeshan|2> pcw do you write your responses in notepad before pasting? :)
[16:42:57] <PetefromTn_> I am not even sure you CAN have both modbus control and analog control input to the drive
[16:43:00] <rob_h> we just have alot of lag ;)
[16:43:05] <PCW> no, to the wrong window
[16:43:19] <bobo_> zeeshan: bucket ---- can have more than one thus several diff fluids ----smaller space needed and can with lid be stored if not using --also swap use between lathe and mill
[16:43:29] <rob_h> how many times have we all done that and wondered why no one replyed haha
[16:43:53] <zeeshan|2> ah bobo
[16:44:25] <rob_h> what is bobo talking about?
[16:44:32] <zeeshan|2> the lubrication system on my machine
[16:44:37] <rob_h> aaah
[16:44:42] <zeeshan|2> theres these two massive valleys in the casting
[16:44:46] <zeeshan|2> had no idea what they were for
[16:44:49] <rob_h> that stuff that fills up the coolant tanks
[16:45:01] <zeeshan|2> i thought it was cooalnt , but its dumping oil in there
[16:45:10] <zeeshan|2> realized im missing the coolant tank :(
[16:45:23] <rob_h> only a sheet metal box
[16:45:35] <zeeshan|2> no brake :(
[16:45:42] <zeeshan|2> but i guess i can bend it on the table
[16:45:59] <PetefromTn_> other than the basic trial and error setup what about the PID analog control is difficult rob?
[16:46:33] <bobo_> plastic bucket for home use
[16:46:35] <rob_h> getting the VFD respond etc like turning a realy laggy servo i guess is one way to say
[16:47:02] <zeeshan|2> bobo_: rofl
[16:47:04] <zeeshan|2> not a bad idea.
[16:47:19] <rob_h> pete just setup DC brake as PCW said... u have a thermal trip inside motor wired to estop or what ever so not like you can over heat the motor
[16:47:38] <zeeshan|2> his vfd has 2 terminals
[16:47:42] <zeeshan|2> where you can wire the thermistor to directly
[16:47:43] <rob_h> and just try it out if looks good you can then go on and finish the atc logic wiring up
[16:47:48] <zeeshan|2> and it'll put the vfd in overheat mode
[16:48:15] <zeeshan|2> does the thermistory get placed on the fins?
[16:48:29] <PetefromTn_> have you ever done an orient using the DC brake like that ?
[16:48:53] <rob_h> no but i can see how it would work
[16:49:17] <PetefromTn_> have you ever even used the braking for any reason this way?
[16:49:54] <rob_h> never had a need i would probly use it on a lathe ifi had a index pin to postion if VFD could not postion properly as you have to be prity close to get the pin in
[16:50:24] <rob_h> would let you put a cheaper vfd on the lathe then too
[16:51:00] <PetefromTn_> I really have no need for positioning on my lathe but even if I did I would probably not try to use the spindle motor to do it.
[16:52:36] <bobo_> Pete I also vote for manually trying motor DC brake -------seeing what results are of turning spindle/tool holder by hand
[16:52:37] <zeeshan|2> i'm sad no one took the cad challenge :(
[16:53:04] <rob_h> of
[16:53:15] <zeeshan|2> every tuesday should be a cad challenge day
[16:53:21] <zeeshan|2> to keep cad skills top notch
[16:53:28] <PetefromTn_> bobo thanks for the input but I really was not looking for votes hehe
[16:53:48] <rob_h> lo have a show of hands shall we
[16:53:58] <zeeshan|2> i vote for dc injection
[16:54:08] <zeeshan|2> actually itake that back
[16:54:13] <zeeshan|2> i vote for selling machine to me for $5
[16:54:25] <rob_h> u dont know to know the delivery cost
[16:54:34] <zeeshan|2> hehe
[16:54:35] <rob_h> ^want to know
[16:55:00] <zeeshan|2> bobo_: http://i.imgur.com/oMM3dbV.png
[16:55:04] <zeeshan|2> seem familiar? :(
[16:55:05] <PetefromTn_> at the end of the day there is a couple people who have spindle control via PID loop in linuxCNC and NOBODY that I know of who has used DC braking to orient before...
[16:55:13] <zeeshan|2> i am missing the quill handle, need to make one :{
[16:55:29] <zeeshan|2> PetefromTn_: they go talk to them
[16:55:31] <zeeshan|2> :-)
[16:55:41] <PetefromTn_> I am talking to them right now
[16:55:42] <anonimasu> zeeshan|2: what challenge?
[16:55:58] <zeeshan|2> [17:19:15] <zeeshan|2> CAD challenge for the day, make it in the least number of steps: http://i.imgur.com/5Qg2tTp.png ; http://i.imgur.com/X9iCXXk.png
[16:56:03] <zeeshan|2> i need one too
[16:57:05] <rob_h> just revolve the switch around middle the put in holes and key
[16:57:20] <zeeshan|2> they are not straight holes :P
[16:57:25] <rob_h> dam i cant type tonight...
[16:57:34] <rob_h> no so just put in a plane on the angle and draw
[16:58:04] <zeeshan|2> text for cad challenge denied! :P
[16:58:15] <rob_h> lol
[16:58:25] <anonimasu> I think I have enough cad challenges at work -_-
[16:58:45] <zeeshan|2> i try to keep open minded about it
[16:58:46] <anonimasu> now for a machining challenge im up :D
[16:58:52] <zeeshan|2> can learn so much
[16:58:54] <zeeshan|2> just like machining
[16:58:56] <anonimasu> make this part in the least amount of steps
[16:58:56] <anonimasu> :D
[16:59:05] <bobo_> zeeshan: the quill handles are beyond the hill where all the lost nuts-washers-other tiny stuff went to
[16:59:05] <anonimasu> err "fixture"
[16:59:06] <zeeshan|2> look at how i'm planning to drill thjose compound holes
[16:59:10] <zeeshan|2> im sure someone can do it better/easier
[16:59:24] <zeeshan|2> bobo_: yes :(
[16:59:35] <zeeshan|2> its pretty straight forward to make though
[16:59:46] <rob_h> put in on the mill and swing the head
[16:59:48] <zeeshan|2> ill turn them on the lathe
[16:59:57] <zeeshan|2> rob_h: never!!!
[17:00:12] <zeeshan|2> too lazy to line it back up :)
[17:00:19] <rob_h> lol does not take long
[17:00:31] <zeeshan|2> dude this is one good example where the lathe would work so good.
[17:00:33] <rob_h> or leave for the next person
[17:00:39] <zeeshan|2> you turn the hub
[17:00:43] <zeeshan|2> then just have your live tool at an angle
[17:00:46] <zeeshan|2> and drill the 4 holes
[17:00:50] <zeeshan|2> _only_ if i had indexing :(
[17:01:02] <rob_h> and a angled drilling head
[17:01:48] <zeeshan|2> ill have to go use the school shop to machine the keyway
[17:01:51] <zeeshan|2> 5 mm.. :/
[17:02:27] <anonimasu> zeeshan|2: that part seems pretty straightforward
[17:02:38] <zeeshan|2> anonimasu: make it! :P
[17:02:44] <anonimasu> draw it up=
[17:02:45] <anonimasu> ?
[17:02:47] <rob_h> if you want a box full
[17:02:49] <zeeshan|2> 3d model it
[17:02:52] <anonimasu> ok
[17:02:59] <zeeshan|2> remember, least number of steps
[17:03:11] <zeeshan|2> at the end you should be able to change the angle
[17:03:14] <zeeshan|2> and everything should work out
[17:03:16] <_methods> yeah someone do his homework for him
[17:03:23] <rob_h> lo
[17:03:25] <zeeshan|2> _methods i already made it
[17:03:26] <zeeshan|2> lol
[17:03:34] <anonimasu> it dosemt mean i'll give hime the solid :D
[17:03:48] <zeeshan|2> rob_h: you have a box full of broaches? :)
[17:04:17] <anonimasu> actually I cant right now S:
[17:04:24] <rob_h> no i whe u said make it.. i ment only if you want a box full
[17:04:26] <anonimasu> work computer's rebooted so I cant get to my cad
[17:04:46] <anonimasu> my home computer went to the shop and the laptop dose have cad :S
[17:04:56] <zeeshan|2> anonimasu: what cad do you use
[17:04:59] <anonimasu> alibre
[17:05:36] <rob_h> EDM it be much fun :)
[17:05:57] <bobo_> anonimasu: your MH700, does the vertical head have a manual operated 90 deg Pin for referance ,after rotating offof vertical ?
[17:06:01] <zeeshan|2> i wish i could store that edm i cam e across
[17:06:03] <zeeshan|2> =[
[17:06:05] <zeeshan|2> don't remind me
[17:06:30] <anonimasu> no
[17:06:37] <zeeshan|2> anonimasu: you have a mh700?! :D
[17:06:37] <anonimasu> there's a encoder
[17:06:39] <anonimasu> yeah
[17:06:43] <anonimasu> mh 700s
[17:06:44] <anonimasu> :S
[17:06:47] <anonimasu> dont forget the S
[17:06:48] <anonimasu> :D
[17:07:12] <zeeshan|2> http://www.maritool.com/Retention-Knobs-CAT40-Pull-Studs/c67_68/p1621/Pull-Stud-Hex-Head-4E-0110-%28-Deckel-,-Maho-%29/product_info.html
[17:07:16] <zeeshan|2> does it use a ott groove pull stud?
[17:07:34] <anonimasu> sandvik ones
[17:07:45] <zeeshan|2> do they look like this?
[17:07:54] <zeeshan|2> these are very distinct
[17:07:57] <anonimasu> but the holders have a maho notch
[17:08:08] <zeeshan|2> theyre like the biggest pull stud out of all cnc machines
[17:08:17] <zeeshan|2> for #40 taper
[17:09:01] <bobo_> picture of the MH700S pull stud ?
[17:09:03] <anonimasu> mhm no
[17:09:14] <zeeshan|2> bobo_: i tried to make an educated guess on the pull studs for the mikron
[17:09:18] <anonimasu> it's BT40 I think
[17:09:20] <zeeshan|2> i stuck a 1" steel round bar in there
[17:09:32] <zeeshan|2> and it engaged :)
[17:09:52] <zeeshan|2> and this is the only .986 pull stud diameter
[17:09:57] <anonimasu> zeeshan|2: I'll post a video once I start running some production onit
[17:10:04] <zeeshan|2> anonimasu: sweet
[17:10:32] <zeeshan|2> also i looked through my notes
[17:10:33] <zeeshan|2> and found this:
[17:10:38] <zeeshan|2> http://i.imgur.com/quUGc6y.gif
[17:10:45] <zeeshan|2> pretty sure the micron is a typo for mikron
[17:11:05] <zeeshan|2> http://i.imgur.com/PAMhKL0.gif
[17:11:09] <zeeshan|2> and thats from the actual standard
[17:13:30] <anonimasu> mhm, mine uses normal pullstuds
[17:13:34] <anonimasu> but they are quite massive
[17:13:52] <zeeshan|2> if you get a chance, try to snap apic please :)
[17:13:54] <bobo_> photo ?
[17:14:33] <anonimasu> I can do it tomorrow
[17:14:57] <anonimasu> and I can get you the sandvik part number if you want a drawing along since I have new ones in a baf
[17:15:00] <anonimasu> bag
[17:15:08] <zeeshan|2> that works too
[17:16:16] <bobo_> MH700S ---432 control?
[17:17:21] <anonimasu> yep
[17:21:57] <bobo_> any idea of floor to top of machine -height for the MH700S
[17:24:36] <anonimasu> bobo_: I have a drawing
[17:25:40] <bobo_> just a guess ---is it over 8 foot ?
[17:26:55] <malcom2073> http://2.bp.blogspot.com/-eB0xoXZYqRI/VMgD5Tlj8AI/AAAAAAAAATk/aP_LrQhNl-o/s1600/machinist.jpg
[17:27:25] <anonimasu> 2475mm
[17:27:36] <anonimasu> (precisely)
[17:27:47] <anonimasu> unless they mistanslated it
[17:28:41] <zeeshan|2> hey
[17:28:45] <zeeshan|2> that would fit in my garage :D
[17:28:51] <bobo_> you mean .00000000 and nothing else
[17:29:05] <anonimasu> haha yeah
[17:29:07] <anonimasu> gemans.
[17:29:15] <bobo_> my garage first !
[17:29:36] <zeeshan|2> i bid $6
[17:29:41] <zeeshan|2> 1$ more than my bid to pete
[17:30:24] <bobo_> you are out of the WILL then
[17:30:29] <anonimasu> with pallet changer 6150mm wide
[17:30:53] <anonimasu> 6150x5200
[17:31:13] <anonimasu> (pallet changer and coolant filtration system)
[17:31:15] <anonimasu> I eman
[17:31:17] <anonimasu> mean
[17:31:21] <zeeshan|2> bobo_: im really impressed by the mikron
[17:31:28] <zeeshan|2> the swiss/germans really build machines good
[17:31:33] <zeeshan|2> its frigging what made in 1980 something
[17:31:38] <zeeshan|2> i did testing
[17:31:40] * anonimasu is the same
[17:31:49] <anonimasu> it's uber all over..
[17:31:50] <zeeshan|2> it has no measureable wear on the .0005 indicator.
[17:31:50] <bobo_> and the MH700S is 2 tone green---ya
[17:31:59] <zeeshan|2> i dont understand how they manage to do that
[17:32:02] <anonimasu> and 7600kg..
[17:32:10] <anonimasu> for the base.
[17:32:14] <anonimasu> and cabinet
[17:32:38] <anonimasu> they didnt cheap on anything in that time
[17:32:56] <anonimasu> what's nice with the maho is that every component is standard stuff(most anyway)
[17:34:12] <zeeshan|2> dop you know how much they cost
[17:34:14] <zeeshan|2> back then, brand new?
[17:34:21] <anonimasu> yes
[17:34:28] <anonimasu> over 700000usd
[17:34:32] <zeeshan|2> HAHAHA
[17:34:35] <zeeshan|2> HAHAA
[17:35:04] <anonimasu> i saw it on some forum when i were researching(practicalmachinist)
[17:35:06] <anonimasu> I think
[17:35:06] * adb own a swiss late from 1932 which do 1/100 mm precision
[17:35:38] <anonimasu> I didnt try the maho fully yet, but I expect to be able to keep 1/100's if needed
[17:35:41] <anonimasu> :)
[17:35:56] <bobo_> Standard for your side of the pond ----in US it can be a big problem
[17:36:55] <anonimasu> zeeshan|2: are you alive
[17:37:18] <zeeshan|2> im alive
[17:37:26] <zeeshan|2> im just suprised at the cost
[17:37:37] <anonimasu> zeeshan|2: the drawbar bolts are called iso/dis 7388/II type B
[17:38:07] <anonimasu> ISO/DIN
[17:38:56] <anonimasu> and the taper is ISO 40 DIN 69871/1
[17:39:49] <zeeshan|2> interesting
[17:39:51] <zeeshan|2> it is different
[17:40:29] <anonimasu> gtg, bedtime
[17:40:30] <anonimasu> laters!
[17:44:18] <bobo_> zeeshan|2 : the spindle drive tabs/dogs ,for tool holders 2 drive slots , are the the same width ? as in not BT holder style --but CAT holder style
[17:44:46] <zeeshan|2> yea bobo they are same width
[17:44:55] <bobo_> good
[17:44:59] <zeeshan|2> you should be able to fit a cat in there
[17:46:05] <bobo_> yes I can , but was thinking of your mill
[17:46:47] <zeeshan|2> bobo_: i remember looking it up
[17:46:55] <zeeshan|2> i think you can fit cat40 in iso40 spindles
[17:47:00] <zeeshan|2> but not iso40 in cat40 spindles
[17:47:03] <zeeshan|2> without modify the dog
[17:49:37] <bobo_> OK ---I thought it was BT vers CAT ,and iso # was just ref. of taper
[17:52:14] <_methods> call a local tooling supplier he'll come over and identify it correctly for you
[17:53:53] <zeeshan|2> http://www.kennametal.com/en/products/20478624/2664259/42041919/54480135/100023576.html
[17:54:00] <zeeshan|2> thats the pull stud anonimasu was talking about
[17:54:05] <zeeshan|2> HDD = 18.8 mm
[17:54:09] <JT-Shop> email Marris and he will tell you
[17:54:11] <zeeshan|2> thats no where clos eto the 25.00 for my spindle
[17:54:16] <zeeshan|2> whos marris
[17:54:27] <zeeshan|2> its kinda a bit late
[17:54:34] <zeeshan|2> i already spend 200 bux in nonreturnable pulls tuds :(
[17:54:44] <zeeshan|2> these better be it!!
[17:55:11] <_methods> oh well stfu about it then lol
[17:55:41] <zeeshan|2> mean
[17:55:44] <_methods> hahah
[17:55:48] <_methods> :)
[17:56:21] <_methods> you got that ajxu you should be smilin all day
[17:56:38] <zeeshan|2> https://www.youtube.com/watch?x-yt-ts=1422327029&v=FIzgxJqpJb0&feature=player_detailpage&x-yt-cl=84838260#t=331
[17:56:38] <_methods> right pullstuds or wrong pullstuds
[17:56:44] <zeeshan|2> lol
[17:56:50] <zeeshan|2> i only have like 8 replacement inserts
[17:56:52] <zeeshan|2> are they expensive?
[17:57:05] <zeeshan|2> hopefully ebay it when the time comes
[17:57:28] <zeeshan|2> i'm amazed by how short they kept this end mill in this video
[17:57:29] <zeeshan|2> :)
[17:57:57] <_methods> yeah they are a bit expensive because they are mits
[17:58:05] <_methods> but nothing too outrageous and they last forever
[17:58:09] <_methods> so they are well worth it
[17:58:49] <zeeshan|2> have you use the apx series?
[17:58:56] <_methods> no never tried them
[17:59:45] <_methods> looking now
[18:00:16] <_methods> looks like a regular r390
[18:00:55] <_methods> yeah standard R390 geometry
[18:01:13] * zeeshan|2 learned something new
[18:01:18] <zeeshan|2> i didnt not know what those inserts were called
[18:01:37] <_methods> it's a sandvik R390 insert
[18:01:43] <zeeshan|2> hm
[18:01:47] <zeeshan|2> these came in a mitsu box
[18:01:49] <_methods> or a knock off
[18:02:05] <_methods> mits' version of the R390
[18:03:38] <_methods> http://www.sandvik.coromant.com/en-us/products/coromill_390/pages/assortment.aspx
[18:04:14] <_methods> sorry this link
[18:04:16] <_methods> http://www.sandvik.coromant.com/en-us/products/coromill_390/Pages/default.aspx
[18:05:11] <_methods> it's like the cutter you'll find in every shop being used in every machine
[18:05:19] <_methods> great general purpose cutter/insert
[18:05:30] <zeeshan|2> honestly ive never seen this type before other than when i got it
[18:05:36] <zeeshan|2> on the mills we used solid carbide
[18:05:42] <JT-Shop> maritool
[18:05:58] <zeeshan|2> cause theyre more accurate than indexable tools
[18:06:06] <zeeshan|2> lathe used indexable tools
[18:06:18] <JT-Shop> I just told him the make and model of my VMC and he told me what pull stud and type of holder it used
[18:06:30] <zeeshan|2> JT-Shop: he told me his best guess
[18:06:32] <zeeshan|2> which is wrong
[18:06:54] <zeeshan|2> my hyd grip thing closes with a diameter of .8 something
[18:07:06] <zeeshan|2> he recommended something with a .7" dia :P
[18:07:22] <zeeshan|2> same as what anonimasu recommended
[18:07:26] <JT-Shop> he knew what mine took is all I know
[18:08:06] * JT-Shop waits for the exothermic reaction to stop on the furnace
[18:14:02] <bobo_> zeeshan|2 on your mill ,can you see what the grip edge shape is of the pulling 3 or 4 fingers that grip the pull stud ?
[18:14:36] <zeeshan|2> 4
[18:14:52] <zeeshan|2> jthornton: whatcha cooking
[18:15:43] <zeeshan|2> https://www.flickr.com/photos/128539016@N05/14996196844/
[18:15:48] <zeeshan|2> you can see it there bobo
[18:16:35] <JT-Shop> making a casting furnace
[18:19:44] <bobo_> looks as if the inside shape is stright vers "C" shape . you may be getting the correct pull studs after all
[18:20:04] <zeeshan|2> bobo_: im just going based on the fact
[18:20:12] <zeeshan|2> that no other #40 taper has a pull stud this big
[18:20:12] <zeeshan|2> lol
[18:20:21] <zeeshan|2> ive looked at so many suppliers
[18:20:30] <JT-Shop> http://gnipsel.com/images/casting/
[18:20:32] <zeeshan|2> one one that comes close to 1" dia is ott groove style
[18:21:29] <zeeshan|2> that looks bad ass!
[18:22:09] <JT-Shop> what does?
[18:22:53] <Nick001-shop> Got a question about a chinese stepper driver. It has a Dir+ and a dir - with a diode drawn between them . I only have a dir lead that I connect to the gecko diver. Do I do the same with the chinese unit and ignore the diode and dir- terminal.
[18:23:32] <zeeshan|2> JT-Shop: the furnace
[18:23:34] <zeeshan|2> and the burner
[18:23:39] <zeeshan|2> i dig the burner
[18:23:42] <JT-Shop> yea, the burner rocks
[18:23:52] <JT-Shop> and simple to make
[18:24:07] <zeeshan|2> i like how you went with the swirld design
[18:24:08] <JT-Shop> I'll have prints for it soon
[18:24:15] <zeeshan|2> to circulate the flame
[18:24:25] <zeeshan|2> to induce turbulence
[18:24:33] <JT-Shop> that seems to be how most furnaces are built
[18:24:47] <JT-Shop> including commercial ones
[18:25:25] <JT-Shop> might take the forms out tomorrow night
[18:25:46] * JT-Shop retires to the couch
[18:27:20] <furrywolf> anyone have some stepper motor cable they want to sell? 16/4 shielded, continuous flex would be perfect I think...
[18:28:17] <furrywolf> I am distinctly displeased with the crap I got... flexible servo stepper cable! is actually alarm cable, stiff enough a 6" section will hold the 25ft roll out horizontal...
[18:29:20] <furrywolf> I have a roll of nice 4+2 separately shielded servo cable, but don't know if I want to waste it on steppers...
[18:34:11] <PCW> Nick001-shop depending on whats driving it you may connect
[18:34:13] <PCW> DIR to DIR and DIR+ to 5V
[18:34:14] <PCW> or
[18:34:16] <PCW> DRI- to GND and DIR to DIR+
[18:34:40] * furrywolf buys more ebay wire
[18:35:39] <PCW> DIR to DIR- and DIR+ to +5V
[18:35:41] <PCW> or
[18:35:42] <PCW> DIR to DIR+ and DIR- to GND
[18:36:34] <PCW> or DIROUT+ to DIR+ and DIROUT- to DIR- (differential)
[18:43:03] <furrywolf> grrr. I fucking give up. my internet connection is sucking too badly to even search for cable, much less purchase it.
[18:43:40] <_methods> you still on dialup?
[18:44:02] <furrywolf> worse. 3g.
[18:44:16] <_methods> ouch
[18:44:41] <_methods> no dsl or cable?
[18:44:51] <furrywolf> nope
[18:45:11] <_methods> wow
[18:45:21] <_methods> where the hell you live?
[18:45:30] <furrywolf> far northern california
[18:45:42] <_methods> heheh got weed but no internet
[18:46:10] * furrywolf doesn't like weed
[18:46:13] <Jymmm> with enough weed, you don't need internet
[18:46:31] <_methods> you're livin in the wrong part of the country to not like weed lol
[18:47:11] <_methods> north of eureka or south of eureka?
[18:48:04] <furrywolf> northeast, not by much.
[18:48:32] <_methods> i went to elementary school in ferndale
[18:49:24] <furrywolf> one of the cities I avoid going to. :)
[18:49:29] <_methods> yeah
[18:49:34] <_methods> not much there
[18:49:44] <_methods> kinetic sculpture race
[18:50:01] <_methods> and that river run or whatever and that's about it lol
[18:50:16] <_methods> what river is that? the eel river
[18:50:26] <unfy> rawr
[18:50:27] * furrywolf has been in the KSR several times
[18:50:49] <_methods> yeah that was the best part of livin there
[18:51:47] <furrywolf> the complete and utter lack of industrial supply, on the other hand...
[18:52:28] <_methods> yeah not much around there
[18:52:44] * furrywolf pokes all the people here who might have spare stepper drive cable
[18:53:42] <_methods> i just use regular hook up wire lol
[18:53:56] <furrywolf> for wires that flex continually?
[18:54:05] <_methods> yeah stranded hookup wire
[18:54:09] <furrywolf> and #16/4, not thin stuff...
[18:54:28] <_methods> i just use 18ga
[18:54:44] <_methods> actually i'll just use whatever i grab lol
[18:55:22] <furrywolf> I'm running 9A/phase... #18 just feels a little thin...
[18:55:33] <_methods> yeah you might come up a bit short there lol
[18:55:42] <_methods> 18 probably not going to cut it
[18:55:46] <Jymmm> Home depot carried 18/4 shielded hookup wire
[18:55:47] <_methods> water cooled 18ga
[18:56:09] <malcom2073> High strand count speaker wire?
[18:56:53] <furrywolf> I suspect the stuff I got on ebay is similar to the home depot stuff... it's obviously intended to be communications cable, not motion control cable. stiff, thin insulation, thick strands.
[18:56:58] <_methods> 14ga should be fine under 15'
[18:57:39] * _methods has no idea how long your run is going to be
[18:57:39] <Jymmm> You're not talking 9a/ph contonously, if ever
[18:58:07] <furrywolf> runs will be pretty short, under 5ft...
[18:59:03] <furrywolf> however, I haven't had any better luck finding cheap-but-good 18/4 either.
[18:59:14] <_methods> go rip the wiring harness out of your neighbors car
[18:59:30] <furrywolf> car wire, other than special sections, is NOT designed to flex.
[18:59:53] <_methods> so many rules
[19:00:06] <furrywolf> even just the wires to power door locks, windows, etc fail just from opening and closing the doors.
[19:00:15] <Jymmm> They have this by-the-foot in stores http://www.homedepot.com/p/Southwire-500-ft-18-4-CL3R-Shielded-Security-Cable-57573044/202316270
[19:00:40] <furrywolf> http://www.ebay.com/itm/16-4-awg-SHIELDED-STRANDED-SECURITY-CABLE-SOLD-BY-THE-FOOT-1-FT-SPEAKER-WIRE-OFC-/171013870651 I suspect that's what the home despot stuff is... and it's junk. that's what I got the first time.
[19:01:20] <Jymmm> how is it junk?
[19:01:48] <PetefromTn_> meh one is 16/4 the other is 18/4
[19:01:54] <furrywolf> it's stiff as fuck, paper thin insulation, and very very coarse stranding. it's designed to be put in a wall and left there, not flexxed.
[19:02:33] <Jymmm> They stuff I have/got was't like tat at all
[19:03:02] <furrywolf> compare it to any proper servo cable, where you'll find fine stranding, thick insulation, and a very tight minimum bend radius even with continuous flexxing. oh, and an actual rating for that, rather than no mention of it.
[19:03:25] <furrywolf> my connection is sucking too badly to load the home depot link it seems... first time timed out, second try just sitting there...
[19:03:46] <_methods> use lynx lol
[19:03:52] <furrywolf> real cable will have braid not foil, too.
[19:04:15] <_methods> i use lynx at work so no one can tell i'm surfin the web
[19:04:25] <Jymmm> and you'll pay he premium price for it
[19:04:29] <furrywolf> the servo cable I have is igus chainflex, and it's much, much better... but it's overkill for this application, as it has two extra separately shielded conductors for a tach, that I don't need.
[19:04:50] <furrywolf> I could just use it and leave the two extra conductors unused, but it's pretty fat because of them and the second shield...
[19:06:07] <Jymmm> I'll pay a premium for coax, but not too much of anything else.
[19:06:39] <furrywolf> ... have you ever built something with wire that needs to flex for every table movement?
[19:07:18] <furrywolf> it's like comparing a cheap stiff plastic extension cord to a nice rubbery soow cable...
[19:07:27] <Jymmm> Yes, but didn't need braided shielding
[19:07:51] <furrywolf> stepper drivers make a lot of noise, and should always have shielded cable.
[19:08:01] <Jymmm> Just just high count strands per lead
[19:08:05] <Jymmm> used*
[19:08:27] <Jymmm> Yes, I used foil shield, not braided
[19:08:36] <furrywolf> good wire is easy to find... way out of my budget. looking for used/cheap. heh.
[19:09:16] <furrywolf> all real systems use good wire, and it's available from many wire suppliers... at several bucks a foot!
[19:10:11] <_methods> jumper cables
[19:10:34] <Jymmm> Yes, I have some of that shitty wire I've picked up over the years, I rearly use it. I was just syaing that I only go out of my way for premium coax.
[19:11:19] <furrywolf> http://www.igus.com/wpck/3538/productoverview_CF?C=US&L=en they made the servo cable I have... it's quite nice.
[19:11:20] <Jymmm> Like UV proof, hi flex, direct burrial, doule shielded, hi dielectric
[19:11:48] <furrywolf> unless you're doing a fancy machine vision project, coax doesn't need to continually flex.
[19:12:29] <XXCoder1> 4.1 million, and the most backed project ever
[19:12:30] <Jymmm> IT does when you're rigging up portable stations
[19:12:32] <XXCoder1> hotda
[19:12:59] <_methods> damn you exploding kittens
[19:13:08] <XXCoder1> it sure exploded.
[19:13:19] * furrywolf doesn't see why
[19:13:33] <XXCoder1> its magic. theoatmeal magic
[19:13:33] <furrywolf> the gameplay seems stupid, the art sucks, the concept is mean to kitties...
[19:13:50] <LeelooMinai> So perfect?
[19:13:51] <furrywolf> very little strategy, mostly luck of the draw.
[19:14:11] <Nick001-shop> <PCW> That's a lot of choices. controlling directly from parport with linux cnc
[19:15:16] <PCW> from a parport:
[19:15:17] <PCW> ParportDIR --> DIR-
[19:15:19] <PCW> DIR+ to +5V
[19:16:34] <PCW> (for step connect the same but make sure you invert the step output in stepconf/HAL since ts active low when wired this way)
[19:17:48] <Nick001-shop> do I get the +5v from a usb connector
[19:18:04] <PCW> thats a safe way
[19:18:30] * furrywolf got an isolated 24v-5v dc-dc, not wanting to use a usb cable
[19:18:42] <PCW> the unsafe way is from a disk connector :-)
[19:20:23] <PCW> it _may_ work the other way but parallel ports usually sink current much better than they source current
[19:22:38] <Nick001-shop> ok - will try it out in the morning - the unit is a HY-DIV268N-%a
[19:23:16] <Nick001-shop> 5A
[19:23:36] <Nick001-shop> Dinner time bye for now
[21:20:53] <PetefromTn_> http://www.pml-pal.com/Accessories/air-collet-closer/ Gonna need something like this soon hopefully LOL
[21:28:51] <PetefromTn_> anyone ever built one of these things from scratch? does not seem like it would be all that difficult once you have a CNC lathe...
[21:32:06] * furrywolf has seen a special collet for holding a dildo to an air cylinder, if that counts
[21:35:54] <furrywolf> http://www.mylovemachine.com/images/jetaime/option-extender.jpg google images++ :P
[21:37:34] <PetefromTn_> http://www.dunhamtool.com/products/cd0034.gif
[21:42:40] <unfy> as... "my love machine" ... that is just wrong
[21:42:43] <unfy> just wrong.
[21:42:58] <furrywolf> why's that?
[21:43:08] <unfy> i'm not posting porn links here :P
[21:44:30] <Jymmm> only got crappy porn huh? YEah, I wouldn't post that either.
[21:44:40] <unfy> XD
[21:44:46] * furrywolf doesn't like porn
[21:45:07] <furrywolf> I do, however, like love machines. too bad they're stupidly expensive, and generally huge and awkward. I should invent a non-sucky one.
[21:48:17] <furrywolf> probably a hollow cylindrical linear actuator with the dildo in the middle of it... much, much more compact than the crank-based systems they all use, since the dildo can retract into the actuator.
[21:49:25] <furrywolf> linear motor is compact, crank and crosshead bearing not so.
[21:54:23] <renesis> how do you not like porn
[21:54:34] <furrywolf> why would I want to look at pictures of people having sex?
[21:54:34] <Vertices> female
[21:54:52] <renesis> there is porn for females who dont like porn
[21:55:01] <renesis> there is porn of everything for everyone
[21:55:10] <renesis> so how can you not like porn!?
[21:55:22] * Vertices watching physics porn
[21:55:23] <renesis> anyway, machines dont have to be big and awkward
[21:55:24] <furrywolf> see above question.
[21:55:43] <renesis> because you can look at videos of people having sex
[21:55:57] <renesis> because it makes your brain release chemicals that get you horny
[21:56:11] <furrywolf> ... why would I want to look at pictures, videos, or prose of people having sex? there, happy?
[21:56:29] <renesis> mostly to get off
[21:56:39] <renesis> thats why most people do it
[21:56:43] <PetefromTn_> http://smg.photobucket.com/user/aboard_epsilon/media/drawbar/dbar3.jpg.html
[21:56:53] * furrywolf doesn't find it interesting
[21:57:06] <renesis> thats a sexy bearing assembly
[21:57:15] <renesis> furrywolf: yeah, wrong porn then keep looking
[21:57:25] <renesis> anyway, you can get a little machine
[21:57:31] <furrywolf> or maybe, you know, I just don't care for porn?
[21:57:35] <renesis> sometimes theyre more useful
[21:57:55] <renesis> because you can throw it in the trunk of a volvo or the back of a hatchback and gtfo
[21:58:27] <renesis> furrywolf: okay well im answering your swuestion litterally because youre pretending to be naive
[21:58:42] <renesis> you would look at it to get horny to get off
[21:59:13] <renesis> swuestion (c) rencorp 2015
[22:00:20] <renesis> guys know anyplace online that fabs rack chassis?
[22:00:37] <furrywolf> I've never seen a really little machine... http://www.mylovemachine.com/sex-machines/PD376200-portable-sex-machine.html is the smallest I've seen yet.
[22:00:48] <renesis> or maybe some decent off the shelf broken down units
[22:01:08] <furrywolf> doesn't seem to mention what the stroke is
[22:01:23] <renesis> oh sorry i was confused i thought you meant the machine to make the sex machine
[22:01:30] <renesis> you just meant the sex machine
[22:02:22] <furrywolf> ... the machine to make a sex machine? that would be a machining center, probably. :P
[22:02:31] <renesis> programmable motion profiles would be pretty neat
[22:02:50] <renesis> well yeah thats what i was saying, you could get a little machine tool
[22:02:56] <furrywolf> perhaps, but as far as I know, they're all crank-based...
[22:03:05] <furrywolf> I have a little machine tool... it's a sherline. :)
[22:03:16] <renesis> im sorry =(
[22:03:36] <furrywolf> http://www.sherline.com/mills.htm
[22:03:39] <furrywolf> ?
[22:04:23] <renesis> i have a taig, sherlines always looked goofy, bunch of people i knew talked shit when i picked out my mill
[22:04:37] <furrywolf> the sherline is an excellent mill... it's just tiny.
[22:04:46] <furrywolf> I got a shoptask mill/lathe combo as my current project.
[22:05:40] <furrywolf> http://fw.bushytails.net/shoptask02.jpg looks like that. (or, well, looked like that... I've gotten one stepper on!)

[22:07:25] <furrywolf> my shoptask is a lot bigger than the sherline... I think I can fit the sherline inside of it. heh.
[22:07:38] <renesis> ground rotating mating surface where they meet so you can tram the column
[22:07:46] <furrywolf> biggest problem with the shoptask is only 3" of Z, and overall chinese build and design quality.
[22:08:17] <renesis> the place i work on breaks has one of those from previous engineering peoples
[22:08:52] <PetefromTn_> http://s72.photobucket.com/user/miltons_stuff/media/PneumaticCloser.jpg.html
[22:08:53] <renesis> no one uses it, has a lot of tooling but they kind of use the space for storage now so cant really get to it and use it
[22:09:00] <furrywolf> I wouldn't use it on brakes... I have a brake lathe for that! two, actually. (one for drums, one on-vehicle one for rotors)
[22:09:14] <furrywolf> renesis: so no one will miss any parts you remove and ship to me, then?
[22:10:11] <renesis> not back there until summer, but likely not
[22:10:18] <furrywolf> heh
[22:10:24] <renesis> dunno if its same machine, if not its close
[22:10:27] <furrywolf> good, I need a new tailstock handwheel, and some other bits. :P
[22:10:46] <renesis> can negotiate
[22:13:32] <furrywolf> is yours cnc or manual?
[22:14:09] <renesis> cnc, open loop stepper
[22:14:24] <furrywolf> same as mine will be when I get it working, then.
[22:14:30] <renesis> maybe one day i will buy it some limit and home switches
[22:14:48] <furrywolf> ... exact same. lol
[22:14:58] * furrywolf has that on the "one day" list too
[22:15:01] <PetefromTn_> I'm thinking some kind of wheel bearing/tapered roller bearing equipped tubular shaft with a sleeve machined to accept the bearings like a hub and then adapt the cylinder to that hub with another bearing reversed against a threaded end large nut for adjustments...
[22:15:34] * furrywolf is too tired to picture what pete just described
[22:15:39] <renesis> wot

[22:17:52] <furrywolf> what about something simple, like a regular drawbar with a drum and a band brake, and just use the spindle forward/reverse with the brake on to tighten/loosen the collet?
[22:20:50] <furrywolf> http://www.ebay.com/itm/OUTBACK-POWER-SYSTEMS-INVERTOR-FX-12-Volt-110-VAC-/201274404281 good deal if someone needs an inverter. (will likely sell FAST at that price)
[22:31:03] * furrywolf curls up and yawns
[22:31:12] <unfy> _methods : still here ?
[22:34:16] <furrywolf> no one in this channel to curl up on. :(
[22:37:08] <unfy> he had posted a link to some eyeglass frame mounted jewlers loops eye piece things. i watched the demo videos on the page for it...
[22:37:46] <unfy> the second video -- whenever the guy was looking through it, he had a hand on the side of the frame to stablize it
[22:37:53] <unfy> making it rather useless
[22:40:15] * SpeedEvil places a curling rink in the corner.
