[00:07:35] <t4nk516> is this EMC support channel?
[02:08:58] <Deejay> moin
[07:54:46] <jdh> any suggestions for a dedicated machine for engraving text in stainless with a 0.074 cutter?
[07:58:43] <archivist> stainless is horrible
[08:00:02] <SpeedEvil> LASER!
[08:00:26] <SpeedEvil> Oh - nvm
[08:00:29] <SpeedEvil> that cutter is hute
[08:00:30] <SpeedEvil> huge
[08:00:33] <jdh> yeah, stainless sucks. And it has to cut with no coolant
[08:00:58] <SpeedEvil> why?
[08:01:10] <jdh> OTOH, it just has to cut 6-9 characters and only 0.035" deep
[08:01:32] <archivist> edm
[08:01:45] <jdh> has to be dry
[08:01:55] <SpeedEvil> jdh: you can do gas coolant
[08:02:01] <SpeedEvil> which helps a little
[08:02:03] <archivist> why
[08:02:50] <jdh> it can't be cleaned afterwards
[08:03:14] <SpeedEvil> distilled water
[08:03:19] <archivist> burrs ok?
[08:03:21] <SpeedEvil> Alcohol
[08:03:44] <jdh> burrs currently get brushed off
[08:03:56] <jdh> or light filing if needed
[08:04:05] <archivist> do this job before final cleaning not after
[08:05:09] <jdh> they are delivered 'clean' and then serialized
[08:05:11] <SpeedEvil> is this to engrave a stainless plaque on some wood or something?
[08:05:38] <jdh> no, it is a serialized part for an assembly
[08:05:48] <SpeedEvil> does the engraving need to be readable, or does it need to be pretty?
[08:06:11] <jdh> the font is fixed.
[08:06:26] <jdh> we have a purpose built machine that currently does it, but it sucks.
[08:06:32] <archivist> I think the work order is silly. doing the serial number first gets rid of problems like that and cheaper
[08:06:42] <jdh> I was hoping a small VMC or tormach style thing coudl replace it
[08:06:54] <jdh> the work order is fixed
[08:07:15] <XXCoder> air coolant with vaccum other side to pick up dust to keep it clean
[08:07:32] <SpeedEvil> IPA I'd think would work fine as coolant
[08:07:55] <SpeedEvil> Plus, you could do the dentist thing
[08:07:56] <jdh> the current one uses air to cool/evacuate chips with a vacuum on the other side.
[08:07:59] <SpeedEvil> spray coolant at...
[08:08:02] <SpeedEvil> yeah - that
[08:08:49] <XXCoder> current one? whats wrong with current one that youre looking for another?
[08:09:03] <jdh> it is the assembly serial number. It isn't known until it is made. If it is damaged post-engraving, a replacement is made with the same number.
[08:09:50] <SpeedEvil> Considered punching?
[08:09:52] <jdh> current one is getting sloppy and is not really made to be fixed.
[08:10:16] <SpeedEvil> Set of carbide numbers, ...
[08:10:56] <XXCoder> interesting. too bad its too expensive to ship it lol would like to have fun with it even as its getting worn
[08:11:08] <jdh> yeah. Wish I could take it home.
[08:14:04] <jdh> so, no suggestions for a small machine to do this, just suggestions that the required method is wrong?
[08:14:38] <XXCoder> speed probably too slow if not automated number changing
[08:14:43] <archivist> stuff not designed for repair needs modification during repair, something one has to do with old clocks, or remanufacture parts from scratch
[08:16:16] <archivist> if your process is that broken will they even accept a replacement machine, "must be done this way syndrome"
[08:20:53] <SpeedEvil> jdh: in principle any decent rigid CNC of the appropriate dimensions to fit your work in.
[08:20:58] <SpeedEvil> jdh: and a suitable clamp.
[08:21:17] <SpeedEvil> You may need to replace cutters fairly often, to keep them sharp enough to cut
[08:21:29] <SpeedEvil> And will need to screw with feeds to get them appropriate
[08:21:39] <SpeedEvil> Is the work of a nice consistent size?
[08:34:09] <jdh> all parts are identical
[08:34:43] <jdh> cutter changes are fine. New machine is fine.
[08:34:54] <jdh> we make about 20/day max
[08:35:27] <jdh> really looking for something between a tormach and a small Haas type VMC
[08:40:41] <SpeedEvil> I assume laser marking or engraving won't work as you have a specific spec?
[08:41:06] <jdh> right.
[08:41:47] <jdh> it would require way too much laser to only make 20/day anyway
[08:45:38] <PetefromTn_> Morning folks..
[08:46:02] <PetefromTn_> OMG I just heard back from the BIG local company about the job I bid yesterday. Apparently I got it!!!
[08:46:42] <PetefromTn_> I am so stoked that they were willing to give me a shot here. They called me this morning to let me know that I got the bid and they needed my contact and mailing information.
[08:47:06] <PetefromTn_> So now the big stress begins. I gotta make this first prototype beautiful and perfect for them. NO PRESSURE LOL
[09:09:22] <jdh> what's the part, if you can say.
[09:09:54] <PetefromTn_> its actually an assembly of six parts that make up a part that I cannot talk about YET.. LOL
[09:12:00] <PetefromTn_> It is a prototype of something they already make that they are changing the design to update its looks. It is a really cool looking assembly of parts tho I wish I could show you guys.
[09:12:19] <jdh> understand.
[09:13:24] <PetefromTn_> lots of curves and angles and really stylized design. I am excited to be able to make it for them.
[09:14:45] <PetefromTn_> Honestly it is much like the rails I have been designing with swooping curves and neat shapes. Four of the six parts are mirror images of each other top and bottom and the other two are what they attach to.
[09:16:42] <PetefromTn_> Good news is I already have the material here to make it from the custom battery tray project and they designer told me he wants to change the model in one area so he is going to send me the new model this afternoon.
[09:17:22] <PetefromTn_> What sucks is I already started to work with the model he already sent so that work is useless now. Gonna have to start over but I only had an hour or two into it at best.
[09:17:38] <Rab> jdh, Taig micro-mill for your stainless engraving needs? You can probably get out for ~$2,500.
[09:17:46] <PetefromTn_> I can understand why he wanted to change it tho after seeing how the thing works it makes sense.
[09:23:54] <jdh> Rab: too small. It would probobably work, but I hate to invest the time into something like that.
[09:25:04] <jdh> it needs to end up where a random non-machinist operator can clamp the part, scan in the number with a barcode reader, come back in a few minutes and remove the part
[09:41:45] <Rab> jdh, so the machine you have now reads the barcode and automatically generates the toolpath for the S/N?
[09:44:18] <jdh> not really. It is a purpose-built machine.
[09:44:46] <jdh> galil board in a PC with a windows app
[09:45:40] <Rab> Hmm...think you can get the software to control a different machine? That seems like the hard part.
[09:46:31] <jdh> no, I don't like the existing code. I'd write something new.
[09:47:44] <jdh> it validates the operator, checks parts/drawing-numbers against a plant database which assigns the number to be engraved.
[09:48:14] <jdh> and OCR's it at the end to verify.
[10:35:54] <ssi> yawn
[10:35:54] <the_wench> wake up ssi
[10:36:03] <ssi> :)
[10:36:17] <ssi> PetefromTn_: you around?
[10:42:53] <PetefromTn_> Sorry SSI yeah man I am here
[10:43:22] <PetefromTn_> Trying to get this encoder mount machined before they hit me with this prototype job model this afternoon
[10:46:30] <ssi> gotcha
[10:48:48] <PetefromTn_> whatzup?
[10:50:18] <ssi> http://www.ebay.com/itm/121422578426
[10:50:19] <ssi> thoughts?
[10:54:51] <PetefromTn_> Interesting... That is the older Sabre model. It is quite similar to my Arrow 500. Looks like it needs some work but it is not horrible really. The broken tool carousel is a concern you would probably have to have another carousel plate machined for it but that would not be too terrible I would think. It comes with some new spindle bearings. Honestly for that price if it runs it is at least reasonable. Personally I think
[10:55:11] <ssi> if the broken carousel just means I can't use those two pockets, it's not the end of the world
[10:56:40] <PetefromTn_> thats true but once the machine was running you could make another carousel on the machine pretty easily most likely. It MIGHT be beyond the travel of the table but you could index each hole from a central point
[10:57:27] <PetefromTn_> I see some nice things about it that I like. For instance the doors on each side of the enclosure all you to open for longer pieces. Mine does not have that.
[10:58:12] <ssi> it would be tough for me to move
[10:58:31] * SpeedEvil passes ssi a tub of protein powder.
[10:58:32] <PetefromTn_> the pendant is nice and deep so you could easily put the computer up there like I did.
[10:58:50] <ssi> SpeedEvil: wat
[10:58:51] <PetefromTn_> if you are interested I would low ball the hell out of them.
[10:59:05] <PetefromTn_> I bet you could get it for $2500.00
[10:59:07] <SpeedEvil> ssi: It'd be easier for you to move if you bulked up a bit
[10:59:57] <PetefromTn_> moving it would be an expense but not too bad really. probably something like $1500-2k if you paid someone to do it all for you.
[11:00:22] <PetefromTn_> Says it is in Louisville, KY.
[11:00:42] <ssi> SpeedEvil: bulked up to what, super fatass? :D
[11:01:14] <ssi> haha I put a 2500 offer on it, and it was instadeclined
[11:01:15] <PetefromTn_> The good news is that it is quite similar to my machine in most respects. Converting it as I have would be relatively simple I would think.
[11:01:26] <PetefromTn_> really?
[11:01:26] <ssi> as was 3000
[11:01:34] <PetefromTn_> damn.
[11:01:46] <PetefromTn_> does the control actually work.?
[11:02:02] <ssi> looks like it
[11:02:13] <ssi> the crt is dead but they have an external monitor hooked up to it
[11:02:59] <PetefromTn_> I dunno it is up to you man it is several years older than my machine but I feel like they are made well. I would just watch it for awhile and after nobody buys it maybe they will accept a lower offer....
[11:03:21] <PetefromTn_> Yeah I saw the new CRT.
[11:03:45] <PetefromTn_> says they will load it for you if you have a trailer...
[11:03:52] <ssi> I don't have a trailer big enough
[11:03:57] <ssi> and I don't have a lift big enough to unload it
[11:04:00] <PetefromTn_> Do you know anyone with a big diesel dually and a commercial trailer.
[11:04:15] <PetefromTn_> hell you can rent a forklift...
[11:04:19] <ssi> I can rustle something up
[11:04:20] <ssi> yeah I know
[11:04:22] <PetefromTn_> a couple hundred bucks..
[11:04:26] <ssi> it's more than that
[11:04:28] <ssi> it's like a grand
[11:04:33] <ssi> that's why I bought a forklift
[11:04:38] <PetefromTn_> WHAA?
[11:04:44] <ssi> it's like $450 for a day's rental
[11:04:47] <ssi> plus $400 delivery
[11:04:51] <ssi> they bring it on a flatbed semi trailer
[11:04:52] <PetefromTn_> I was going to rent one here and it was like three hundred or so?
[11:05:10] <PetefromTn_> damn thats expensive.
[11:05:14] <ssi> YEP
[11:06:26] <PetefromTn_> however if you borrowed a friends trailer and truck, paid for gas both ways, bought him a case of beer or two, you would be loaded with the machine back at your shop for not too much money really.
[11:06:46] <ssi> yeah that part I can handle
[11:06:49] <PetefromTn_> I rented machine skates to move the thing around once it was on the ground. Just went slow and careful.
[11:07:16] <PetefromTn_> It's a nail biter I won't lie to you. but it was not too bad really.
[11:07:17] <ssi> how'd you get it on and off the skates?
[11:08:00] <PetefromTn_> I used a porta power kit I bought at Northern tool and used cribbage boards moving a corner at a time
[11:08:05] <ssi> ahh
[11:09:04] <PetefromTn_> just jack it up a touch, stick boards in until the skate is free, then once all the skates are out work your way around each side taking one board out at a time until it is close enough to the ground to install the leveling screws.
[11:09:05] <ssi> eh for now I probably just need to get the 704 running
[11:09:33] <PetefromTn_> took all of an afternoon to get it where it is..
[11:09:46] <ssi> yeah it's mostly just the getting it off the trailer issue
[11:09:59] <ssi> and then the big question of whether I should put it at the house or at the airport
[11:10:11] <ssi> if I put it at the house, I'm gonna have to tear the fascia up like you did
[11:10:11] <PetefromTn_> is there nobody nearby that has a larger fork you can borrow for a couple bucks/beers?
[11:10:18] <ssi> not that I know of
[11:10:38] <ssi> at the airport one guy used to have a nice newish 10k lift but it was a lease and he turned it in
[11:10:45] <ssi> now he has a clapped out old junky 5k lift
[11:10:53] <PetefromTn_> I dunno man. I am sure once you got it running you could make some money back on the whole deal...
[11:11:00] <ssi> I won't count on that
[11:11:09] <ssi> I'm bad at making money off my machines :P
[11:11:11] <PetefromTn_> why?
[11:11:13] <PetefromTn_> aah
[11:11:33] <PetefromTn_> shame you got some nice toys down there you could make some cash if you wanted to.
[11:11:35] <ssi> I'm trying to figure out if I can make speaker box kits with the laser
[11:11:51] <PetefromTn_> I am sure you could. Make me one LOL'
[11:13:03] <PetefromTn_> A guy I know on Facebook says the place he works for has a HAAS Tl2 they are selling to upgrade to a live tooling lathe. Damn I would love to have that machine here.
[11:13:12] <ssi> heheh
[11:16:02] <PetefromTn_> ya know I wonder if those offer turn downs were automatic and not representing the real interest of the owner.
[11:21:08] <skunkworks> https://groups.yahoo.com/neo/groups/mach1mach2cnc/conversations/messages/145888
[11:21:22] <Connor> PetefromTn_: What offer turn downs ?
[11:23:12] <PetefromTn_> SSI make offers on a CIncinatti Sabre 500 VMC on Ebay and they returned immediately turned down.
[11:23:51] <Connor> May have some sort of low-ball amount threshold.
[11:24:12] <PetefromTn_> sure
[11:32:55] <PetefromTn_> http://imgur.com/OuP7Q91 Encoder mount almost done!
[11:33:10] <JT-Shop_> goodby, see you Sunday
[11:51:12] <diepchess> hi
[11:52:26] <ssi> Connor: highest one I put in was $3000 on a machine that's got a $4500 buy it now
[11:52:46] <Connor> He probably has it $4k mark
[11:53:27] <ssi> man, laser is weird and counterintuitive
[11:53:56] <ssi> I have 1/2" birch ply cutting pretty well, at 14mA (about 50W), 1600ppi, and 6 ipm
[11:54:02] <ssi> nothing I do will make it cut any faster
[11:54:43] <Connor> Can you speed it up and do multiple passes ?
[11:55:01] <SpeedEvil> ssi: ass assist?
[11:55:03] <SpeedEvil> gas
[11:55:15] <diepchess> aha that 268N motor driver they offer is in fact a TB6600 driver
[11:55:30] <ssi> I have air assist
[11:55:39] <ssi> haven't tried screwing with the pressure
[11:55:55] <SpeedEvil> oxy-acetylene assist
[11:55:59] <ssi> lul
[11:56:11] <ssi> Connor: yeah I need to run some tests and see if I can cut faster in multiple passes
[11:56:39] <Connor> If you had Z movement.. that would be better.. then you could adjust your focal length..
[11:56:46] <Connor> on each successive pass
[11:56:47] <SpeedEvil> maybe
[11:56:50] <SpeedEvil> indeed
[11:59:37] <ssi> focus isn't really the problem with this
[12:00:21] <SpeedEvil> Focus can optimise cutting pattern
[12:01:22] <ssi> I know
[12:01:28] <ssi> and I'm waiting on a 3" lens, which should help
[12:01:31] <ssi> but damn china is slow
[12:01:46] <Connor> I know very little about laser cutters..but.. 1/2" is pretty thick.. if you cut maybe 1/4" deep then adjust focus.. wouldn't that work faster ?
[12:03:14] <SpeedEvil> Connor: it may do - it depends on 'stuff'
[12:03:24] <SpeedEvil> ssi: what's the shape of the cut left?
[12:07:15] <stt_michaelz> whats the benefit of a laser over router for cutting ply?
[12:07:29] <stt_michaelz> apart from needing a spindle motor & cutters ofc :P
[12:09:30] <ssi> SpeedEvil: it's pretty narrow
[12:09:55] <ssi> it's hard to say right now how much bevel there is, cause I'm still working on squareness
[12:10:07] <ssi> stt_michaelz: main benefit for me right now is I have a laser, and I don't have a router
[12:10:34] <stt_michaelz> :) thought so
[12:20:10] <jdh> less mess
[12:21:21] <ssi> less mess, less noise, less kerf waste
[12:21:39] <ssi> but it's comparably harder to cut thicker materials, and you have to be willing to tolerate the burnt edge
[12:22:09] <PetefromTn_> and the smoke and smell hehe
[12:22:37] <jdh> can you cut HDPE?
[12:22:43] <SpeedEvil> laser + router would be interesting
[12:22:56] <SpeedEvil> router for the rough cutting of thick stuff, and laser for the fiddly bits
[12:23:03] <SpeedEvil> say where you want square corners
[12:24:10] <ssi> jdh: haven't tried
[12:24:31] <ssi> HDPE/milk bottle plastic Catches fire and melts It melts. It gets gooey. Don't use it.
[12:25:01] <jdh> cuts nicely on my router
[12:25:11] <SpeedEvil> I do hope you've got a nice extraction system ssi
[12:25:27] <ssi> I have exhaust
[12:25:28] <SpeedEvil> i mean - plywood isn't too bad
[12:25:31] <ssi> I dunno if I'd call it "nice"
[12:25:38] <SpeedEvil> But some plastics are lethal
[12:25:47] <ssi> if I could get around to finishing eclosing the machine, it'd work really well
[12:25:52] <ssi> as it is, it gets 75% of the s moke
[12:26:00] <ssi> I'm not cutting any plastics right now
[12:26:11] <ssi> I cut a little bit of acrylic, but mostly I'm just cutting hardwood plywood
[12:26:56] <ssi> I just took the carriage apart :P
[12:27:06] <ssi> I need to come up with a better way to mount the head, so it's easier to adjust for square
[12:27:24] <stt_michaelz> mm we get most of our metal laser cut .. although we've had some stuff water jet and wire cut occasionally
[12:27:25] <jdh> gimbal?
[12:28:03] <ssi> no, nothing that complex
[12:28:12] <ssi> it's attached to the carriage plate with nuts on the backside,
[12:28:23] <ssi> and there's not enough room to get a wrench on the nuts when the carriage is installed on the machine
[12:28:34] <ssi> so I'm gonna drill and tap holes for it instead, so it can be adjusted entirely from the front
[12:29:46] <jdh> I have billions of bolts/screws, but very few nuts.
[12:29:58] <jdh> I don't really care for them.
[12:54:12] <SpeedEvil> https://www.youtube.com/watch?v=D-8NXSvUlbw - fun - winding large toroidal inductor
[12:59:06] <CaptHindsight> surprised to see it unwind the wire off the end of the spool
[12:59:32] <CaptHindsight> end/side
[13:02:33] <SpeedEvil> yeah
[13:06:53] <diepchess> hello
[13:07:09] <diepchess> which endstop are you using for determining end of ballscrew, and start ballscrew?
[13:07:21] <diepchess> as the 3d printer endstops are notoriously unreliable with some dirt nearby
[13:07:36] <diepchess> here http://www.ebay.com/itm/4-Pcs-x-Mechanical-Endstop-For-3D-Printer-XYZ-Axis-Mech-limit-switch-/131271148185?pt=LH_DefaultDomain_0&hash=item1e905ec299
[13:08:41] <CaptHindsight> diepchess: you can try hall effect/magnetic or optical limit switches, but optical can get dirty as well
[13:09:03] <diepchess> which ones are you using?
[13:09:38] <diepchess> i'm considering using optical one and then as emergency behind it this 1.25 dollar mechanical endstop
[13:10:25] <CaptHindsight> http://www.ebay.com/itm/370987594239 these are low cost inductive types
[13:10:29] <diepchess> note 1.25 dollar for this is bit pricey
[13:11:08] <diepchess> that's wayy too expensive for something simpler
[13:11:18] <diepchess> 16 dollar for 4 = 4 dollar a piece
[13:11:32] <diepchess> for something that just has to interrupt a signal or give one
[13:11:45] <diepchess> 16 / 5 = 3+ dollar
[13:11:45] <CaptHindsight> diepchess: I don't have any 3d printer toys. Mine are all lab units
[13:11:56] <diepchess> it's meant for cnc milling machine
[13:12:01] <ssi> CaptHindsight: those look decent for the money
[13:12:03] <diepchess> for 3d printer, a single endstop is enough :)
[13:12:47] <diepchess> *wondering how much SSI's lunch cost today :)
[13:12:57] <ssi> I haven't had lunch yet
[13:13:12] <ssi> but I also know what things cost
[13:13:15] <CaptHindsight> ssi: I have to mount them in polypropylene or similar to get them to accurate and repeatable
[13:13:23] <ssi> hm
[13:13:32] <CaptHindsight> to be
[13:14:37] <CaptHindsight> mounting them directly in aluminum angle had a great effect on range and repeatability
[13:15:53] <CaptHindsight> I use them on low resolution belt driven positioners
[13:16:05] <archivist> dont let curly chips near them either
[13:16:29] <kfoltman> archivist: you mean crisps? :P
[13:17:03] <archivist> kfoltman, these yanks think of swarf as chips :)
[13:17:16] <kfoltman> mmmm swarf ;)
[13:17:32] <archivist> ready salted swarf
[13:17:40] <kfoltman> with battered code
[13:18:56] <archivist> why you need hand turning for one offs http://www.collection.archivist.info/archive/DJCPD/PD/2014/2014_09_11_ratchet_direction_knob/
[13:19:14] <stt_michaelz> rofl
[13:19:46] <archivist> that is done with a graver like a wood turner
[13:20:46] <kfoltman> archivist: this is an one off?????
[13:20:56] <CaptHindsight> http://www.ebay.com/itm/Magnetic-switch-aleph-PS-3150-Magnetic-proximity-switch-normally-open-good-/131263261805 $1.99 and only 2 wires
[13:20:59] <kfoltman> *a one off, damnit
[13:21:11] <archivist> yes customer wanted the lever replacing
[13:21:19] <kfoltman> archivist: damn!
[13:21:32] <kfoltman> looks awesome
[13:21:40] <archivist> I did cnc the thread you cannot see
[13:21:45] <skunkworks> wow - that wrench has been used as a hammer a lot...
[13:22:14] <kfoltman> archivist: for those two phillips(?) screws?
[13:22:28] <archivist> my first comment this is foreign an not worth it, but it was his dads....
[13:22:47] <archivist> kfoltman, no that lever is screwed in
[13:23:12] <kfoltman> archivist: I thought you've turned the whole thing from scratch :)
[13:23:38] <diepchess> ah here, 10 for 3 dollar and capable 125 volt @ 4A. http://www.banggood.com/10Pcs-KW123-Micro-Limit-Switch-Roller-Lever-5A-125V-Subminiature-p-928002.html
[13:24:02] <kfoltman> needs really small screws?
[13:24:04] <CaptHindsight> http://www.ebay.com/itm/10pcs-Roller-Lever-Arm-PCB-Terminals-Micro-Limit-Normal-Open-Close-Switch-KW12-3-/310931008022 US $2.09 for 10 pcs
[13:24:09] <archivist> kfoltman, I did this is the method http://www.collection.archivist.info/archive/DJCPD/PD/2014/2014_09_07_Lorch_lathe/IMG_1823.JPG
[13:24:41] <archivist> #4 40 tpi on the end of the lever part
[13:24:52] <diepchess> good find Captain
[13:25:03] <CaptHindsight> diepchess: ^^ those are about the cheapest you'll find
[13:25:29] <diepchess> if you buy 1000 they are 6 cents a piece.
[13:25:44] <CaptHindsight> how many until they are free?
[13:26:05] <kfoltman> archivist: do you have a closeup of the thread?
[13:26:14] <archivist> kfoltman, no
[13:26:31] <diepchess> would be very optimistic to buy 1000 :)
[13:26:40] <archivist> just ordinary UNC but .112" dia
[13:26:43] <kfoltman> diepchess: or pessimistic
[13:27:12] <kfoltman> diepchess: if I buy Chinese linear bearings, I only buy one or two extra, but I'm not *that* much of a pessimist ;)
[13:27:27] <diepchess> oh i bought some thousands bearings in china
[13:28:01] <diepchess> shipment was more than total price of package :)
[13:28:26] <diepchess> then you get the package where you paid 60 dollar shipment for, and it says 35 yuan which is like 7 euro :)
[13:28:26] <kfoltman> not unheard of
[13:30:16] <CaptHindsight> SpeedEvil: https://www.youtube.com/watch?v=53VKxQSvJ7Q diy version (video features harpsichord for background music)
[13:32:35] <diepchess> linux CNC is eating gcode?
[13:32:59] <diepchess> what software do you use to convert a STL or something like that to a toolpath for linuxcnc?
[13:36:08] <archivist> wet cam, inside rear of skull
[13:37:54] <Jymmm> archivist: Isn't that a bit cranial?
[13:38:19] <archivist> yes
[13:38:24] <Jymmm> =)
[13:38:35] <CaptHindsight> I think OpenSCAM was a poor choice for the name
[13:39:56] <diepchess> looks nice though the screenshots of openscam
[13:39:58] <diepchess> great name
[13:40:00] <Rab> Way more professional than "The Gimp".
[13:40:23] <diepchess> boy am i lucky i build a 3 axis simple cnc machine
[13:40:30] <diepchess> openscam being 3 axis...
[13:41:01] <diepchess> openscam being open source, why is it openscam.com and not openscam.org?
[13:41:38] <CaptHindsight> http://pycam.sourceforge.net/
[13:42:34] <diepchess> ah pycam it is
[13:42:46] <diepchess> openscam is simulating the toolpath that pycam generates?
[13:42:52] <diepchess> in order to take a good look what happens?
[13:43:18] <CaptHindsight> http://www.repetier.com/
[13:43:35] <archivist> you can write gcode yourself, it is a good idea to try it
[13:43:49] <diepchess> i already wrote gcode archivist
[13:44:07] <archivist> when you make a more complex machine you have to write the gcode
[13:44:14] <diepchess> so no thanks for writing it for a cnc milling machine :)
[13:44:34] <CaptHindsight> http://fabmetheus.crsndoo.com/overview.php Skeinforge
[13:44:45] <diepchess> that would be a lot of effort archivist
[13:45:02] <CaptHindsight> http://slic3r.org/
[13:45:02] <archivist> not really, linuxcnc has loops as well
[13:45:04] <diepchess> the open source software goes till 3 axis toolpath generation/simulation?
[13:46:15] <CaptHindsight> https://code.google.com/p/heekscnc/ don't recall if STL was one of the formats it can import
[13:46:38] <diepchess> which program you prefer Captain?
[13:47:51] <CaptHindsight> I haven't used STL in a while
[13:48:19] <diepchess> solidworks?
[13:48:49] <diepchess> i design my stuff in FreeCAD nowadays
[13:56:51] <archivist> diepchess, have you seen this style of gcode though http://www.archivist.info/cnc/helical_worm2.ngc
[13:57:29] <diepchess> archivist: only been busy with the gcode of 3d printers
[13:57:32] <archivist> 3 lines to cut a helical, not 3 million from a cam prog
[13:57:59] <diepchess> i programmed in coordinates and millimeters in openscad
[13:58:04] * archivist notes line 1 comment error :)
[13:58:05] <diepchess> lot of times you make mistakes
[13:58:25] <diepchess> always have to see output
[13:58:47] <archivist> you can see the path in axis
[13:59:55] <diepchess> what about the problem of moving 2 axis in parallel to get to a point?
[14:00:02] <diepchess> say you want a line at perfect 45 degrees
[14:00:14] <diepchess> one of the motors will receive the command sooner than the other isn't it?
[14:00:23] <archivist> no
[14:00:58] <archivist> the trajectory planner and motion control get it right
[14:01:49] <diepchess> is there opcodes in GCODE for that?
[14:01:56] <diepchess> "move in parallel axis X Y Z..."
[14:02:48] <archivist> you can use variables and loops to achieve something like that
[14:03:33] <diepchess> do you have ATC at home?
[14:04:04] <archivist> no
[14:04:18] <diepchess> maybe i do attempt to build one using self designed robotarm
[14:04:25] <diepchess> with small camera
[14:04:38] <diepchess> camera with robot vision
[14:04:51] <diepchess> camera FOR robot vision software
[14:05:17] <diepchess> will be interesting to do attempt there - ineed to write that robot vision code anyway :)
[14:05:22] <diepchess> but is for 2015
[14:06:14] <kfoltman> I was thinking of tool changing yesterday (manual, just less finicky), anything wrong with having a "key" shaped like a negative of an endmill in a chuck, and using that to fasten the bit so that it always sticks out at (roughly) same height?
[14:06:49] <diepchess> you don't want an ATC?
[14:07:34] <archivist> you can pre set tools in holders and keep the offsets in the tool table, that works with a manual change
[14:08:01] <archivist> that is how I use the cnc lathe
[14:08:08] <diepchess> and ring an alarm when you lie in bed or drink coffee that you have to change the tool?
[14:08:41] <archivist> the program stops and waits for you to change tool on a manual setup
[14:09:01] <diepchess> that will be version 1.00 of my CNC yeah
[14:09:07] <roycroft> what kind of machine are you talking about and what kind of collets?
[14:09:30] <diepchess> if that software works the size doesn't matter roycroft
[14:09:47] <archivist> size always matters :)
[14:09:48] <diepchess> just bit heavier motors for robotarm needed
[14:10:17] <diepchess> if you change the tools at same spot you can avoid lengthy robot arm needed
[14:10:19] <roycroft> i guess i'm not sure what you're talking about
[14:10:28] <roycroft> the quick change system itself, or indexing the tooling
[14:10:43] <diepchess> about small robot arm that is doing same operation like you do by hand
[14:10:52] <diepchess> and sofware with a camera that steers it
[14:11:03] <diepchess> without the camera you would need very expensive robot arm
[14:11:27] <archivist> why would you need a camera, you already know where every thing is
[14:11:32] <roycroft> ok, i have no useful input on that :)
[14:11:54] <diepchess> archivist: accurate and strong robot motors very expensive
[14:12:22] <diepchess> cheap strong robot motors like 10 dollar a piece
[14:12:28] <archivist> you can use steppers for the tool changer
[14:12:34] <diepchess> need small camera to correct errors
[14:12:53] <archivist> use encoders, far easier
[14:13:10] <diepchess> too expensive
[14:13:16] <diepchess> good software makes it dirt cheap :)
[14:13:21] <diepchess> just the software needed
[14:13:48] <diepchess> if i drill/mill here
[14:13:58] <diepchess> sometimes some tools have remnant aluminium at them
[14:14:14] <diepchess> without camera no chance of correcting that bugfree easily
[14:14:41] <diepchess> soon gets expensive without error correction software
[14:15:06] <diepchess> using steppers for robot arm is not so easy if robot arm is bit longer
[14:15:20] <diepchess> first question is what strength stepper you had in mind?
[14:15:50] <archivist> sufficient
[14:16:05] <diepchess> depends heavily upon what collett then
[14:16:30] <diepchess> it has to lift several kilo's at end of robot arm
[14:16:50] <archivist> remember the xyz of the cnc can move to the tools
[14:17:11] <diepchess> advantage of robot arm is you do not lose bedspace
[14:17:48] <archivist> you can move the tool rack into/out with one axis
[14:18:09] <diepchess> yup
[14:18:24] <diepchess> and have massive amount of tooling there
[14:18:47] <diepchess> if robot arm works, doesn't matter whether you have room for 200 tools there or 4
[14:19:03] <kfoltman> that depends on the stroke on the robot arm
[14:19:10] <diepchess> with small camera you do not need very accurate movement for robot arm
[14:19:37] <diepchess> we keep the robot arm at the same Z position
[14:20:30] <diepchess> we have the spindle move slowly down in Z position when we screw the cap back on
[14:20:55] <kfoltman> screw it on how? gripper?
[14:21:17] <diepchess> that tool how you call it in english to tighten it
[14:21:27] <kfoltman> key?
[14:21:30] <diepchess> yes
[14:21:44] <kfoltman> but then you need to know at what angle to insert the key
[14:21:54] <kfoltman> (assuming the nut is rotationally asymmetric)
[14:22:04] <diepchess> have cheap camera for that kfoltman
[14:22:10] <diepchess> camera's are $9.99
[14:22:12] <archivist> I think you need to watch a few tool changers on youtube
[14:22:13] <diepchess> it's about good software
[14:22:22] <kfoltman> sure as long as you can do the CV part for this
[14:22:28] <diepchess> that is expensive ones archivist
[14:22:44] <archivist> they work
[14:22:44] <diepchess> i am making the CV anyway for other projects
[14:22:47] <diepchess> closed source though
[14:22:49] <diepchess> mine
[14:23:04] <diepchess> building robots
[14:23:09] <diepchess> tanks
[14:23:11] <diepchess> with arm on it
[14:23:30] <kfoltman> eight legged tanks
[14:23:37] <diepchess> that's not a tank
[14:23:43] <diepchess> that's a research project
[14:23:49] <diepchess> a tank has tracks
[14:24:17] <diepchess> forget robots that walk for now
[14:24:22] <diepchess> they eat too much power
[14:24:29] <kfoltman> nevermind me, just doing stupid puns
[14:24:33] <diepchess> only interesting for army and gonna cost $20 million a piece
[14:25:00] <diepchess> good robot gripper from roboteq? $18000
[14:25:24] <kfoltman> by "cameras are $9.99" you mean what? I got an endoscope camera for about that much, but it's fairly noisy
[14:25:52] <diepchess> simple robot vision camera is $9.99 cannot look far away though, at most 60 centimeters or so
[14:26:04] <kfoltman> low dynamic rate too, so any chroma-based detection is going to be hit and miss I think
[14:26:15] <diepchess> forget jpg camera's for robot vision
[14:26:15] <PetefromTn_> Encoder mounts for my Cincinatti Arrow 500 VMC are done. I made an extra one for a friend in New Zealand who is doing the same retrofit as mine.
[14:26:31] <PetefromTn_> http://imgur.com/KNALBv6
[14:26:43] <kfoltman> diepchess: so which ones do you mean, standalone modules that connect via, say, DCMI?
[14:27:05] <diepchess> kfoltman: http://www.youtube.com/watch?v=u6d8eKvegLI
[14:27:12] <Connor> PetefromTn_: That the start of the encoder ?
[14:27:19] <PetefromTn_> START??
[14:27:20] <Connor> mount.
[14:27:21] <diepchess> kfoltman: www.robotshop.com
[14:27:27] <PetefromTn_> That IS the encoder setup really..
[14:27:44] <Connor> what's under the black lid ?
[14:28:03] <diepchess> he worries about chrome metal not detected by the camera Connor
[14:28:10] <diepchess> those camera's are BAD
[14:28:15] <diepchess> it is however meant for error correction
[14:28:21] <diepchess> not for clever stuff
[14:29:01] <PetefromTn_> All I need to do now is turn a tube to go into a pocket underneath the plate and get some hardware and it is ready to be installed.
[14:30:00] <diepchess> PetefromTn_: we were discussing ATC using simple robotarm
[14:30:04] <Connor> click the wrong button and dumped the channel
[14:30:24] <Connor> diepchess: I wasn't.. I was talking to pete about his encode mount / enclosure
[14:30:47] <diepchess> confusion then connor, sorry
[14:31:11] <diepchess> as someone suggested encoder
[14:31:30] <Connor> PetefromTn_: looks good.. is the part under the cover hollowed out ?
[14:31:50] <PetefromTn_> no it looks like the other piece outside .
[14:32:00] <PetefromTn_> The black thing is the original cover that housed the resolver.
[14:32:08] <Connor> okay.. Why 2 ?
[14:32:10] <PetefromTn_> The back side of the plate has a round recess..
[14:32:17] <PetefromTn_> One for Brendan in NZ..
[14:32:23] <Connor> Ahh.. okay
[14:32:48] <pcw_home> Thats a serious looking encoder mount, what was there before?
[14:32:59] <Connor> resolver
[14:33:22] <pcw_home> Ahh
[14:33:50] <PetefromTn_> yeah it replaces the original resolver that came in the motor. The motor spins 12k so I figured it would be best if it was beefy.
[14:34:41] <diepchess> kfoltman: on the legged research projects. just one question: how do you get over a trench with them and what if 1 leg of them falls into a hole?
[14:36:21] <kfoltman> retract the leg?
[14:36:45] <diepchess> it already has been broken then
[14:37:17] <kfoltman> continue with remaining, functional legs?
[14:37:19] <diepchess> abrams m1a1 is way cheaper and has a very clever and intelligent crew
[14:37:55] <diepchess> and such, by now owned by google, robot is like $20 million a piece. whereas dead soldier is very cheap. So soldiers cheaper
[14:38:18] <diepchess> anyway
[14:38:31] <diepchess> back to the subject: cheap ATC is interesting
[14:38:39] <kfoltman> certainly
[14:38:49] <diepchess> i will try in 2015!
[14:38:56] <Connor> ls
[14:41:48] <Connor> PetefromTn_: Trying to find the firmware that PCW sent to me for your encoder setup
[14:42:17] <PetefromTn_> excellent
[14:44:02] <Connor> Not so excellent.. I don't remember when, or the file name.. or the instructions...
[14:47:14] <PetefromTn_> not too good..
[14:49:03] <pcw_home> probably 5i25_7i77x1_IMS.bit
[14:49:33] <Connor> Okay.. I do have a file like that in my downloads dir.
[14:49:52] <Connor> Dated March 28th
[14:50:04] <PetefromTn_> BTW thank you so much for the work you put in on the programming Pete and well both of you...
[14:50:30] <Connor> pcw now trying to remember what pins were involved...
[14:51:06] <Connor> pcw_home: If memory serves.. we use a jumper clip on the 26 pin connector.. and jumper 1 and 2
[14:51:18] <Connor> then.. from there it's all hal configuration..
[14:51:31] <Connor> I could have sworn I saved out notes..but.. can't find them.
[14:52:17] <pcw_home> if you download the latest mesaflash (and you configure the card) , it can preint a pinout for you
[14:52:28] <pcw_home> print
[14:56:46] <pcw_home> pretty sure it requires a jumper between GPIO17 and GPIO18
[14:56:47] <pcw_home> on the header which would be pin 1 and 2
[14:57:06] <Connor> right. That's what I recall as well.
[14:58:43] <pcw_home> one pin needs to be an input (the indec mask pin) and the other an output but I dont recall which
[14:58:45] <pcw_home> I'll find the source pinout file and check later today
[14:58:55] <Connor> <font color="#A82F2F"><font size="2">(02:14:03 PM)</font> <b>pcw_home:</b></font> so in hal you wire the prox signal to an output on P2 pin1 (GPIO17)<br/>
[14:58:55] <Connor> <font color="#A82F2F"><font size="2">(02:14:05 PM)</font> <b>pcw_home:</b></font> and i make firmware that has index mask for (what channel) on P2 pin2 (GPIO18)<br/>
[14:59:21] <ssi> dangit
[14:59:49] <Connor> I just found the log file with all the notes.
[15:00:04] <pcw_home> OK good so GPIO17 needs to be set as an output bit
[15:01:44] <Connor> God I love log files. :)
[15:01:52] <Connor> They remember so much better than I do. :)
[15:02:11] <ssi> haha
[15:02:33] <ssi> I can't for the life of me get the cut square in one dimension
[15:05:21] <Connor> don't you have to cut in 2 dimensions to be square to something? :)
[15:06:51] <ssi> you know what I mean :P
[15:08:39] <ssi> I'm shimming under the bolts that hold the head to the carriage to try to change the beam angle
[15:08:46] <ssi> and it doesn't seem to react like I expect
[15:09:03] <ssi> the interaction between the mirror in the head and the lens is odd
[15:12:04] <skunkworks> any sources for computer dynamic embedded boards? liek sbc-sxe?
[15:12:15] <skunkworks> ebay doesn't :)
[15:14:57] <PetefromTn_> Connor Hey man sorry ya there?
[15:15:07] <SpeedEvil> skunkworks: ?
[15:15:36] * Deejay waves his hand towars PetefromTn_
[15:15:39] <Deejay> +d
[15:16:43] <PetefromTn_> Hey deejay!
[15:19:04] <CaptHindsight> skunkworks: these guys? http://www.cdynamics.com/default.aspx
[15:19:23] <skunkworks> right
[15:19:30] <skunkworks> but vintage 1995...
[15:19:52] <skunkworks> (386)
[15:19:57] <skunkworks> bbl
[15:20:16] <Deejay> hey PetefromTn_ :)
[15:41:25] <ssi> I think it's about as square as I'm gonna get it :P
[15:42:47] <PetefromTn_> Hows it going Deejay? What is square your head SSI?
[15:43:27] <Connor> PetefromTn_: Yea. What's up?
[15:44:00] <PetefromTn_> I lost connection when we were chatting about the encoder programming. Did you find what you needed?
[15:44:08] <Connor> PetefromTn_: I think so.
[15:44:16] <PetefromTn_> Awesome..
[15:45:06] <PetefromTn_> I am going to head down tomorrow and get a tiny tap and some screws for this encoder and then I need to machine the shaft for the mill spindle. I should be able to get this thing assembled and installed by tomorrow night.
[15:45:54] <PetefromTn_> There is still the question of the cabling. As we talked about before the Resolver had a heavy stranded cable that went to the spindle motor but it is short one or two wires for the differential encoder.
[15:46:03] <PetefromTn_> The encoder comes with a ribbon cable on it.
[15:46:32] <PetefromTn_> I am trying to figure out the best way to get the encoder information back to the electronics enclosure safely so we can hook everything up.
[15:46:40] <PCW> shielded twisted pair is best
[15:46:55] <PetefromTn_> yeah but this has like ten lines?
[15:47:06] <PCW> shield grounded and 7I77 end only
[15:47:23] <PetefromTn_> and it has to go thru the cable chain where it will be always constantly in motion.
[15:48:12] <PetefromTn_> So I presume I need some kinda soft extension chord style wiring so it will handle that constant bending.
[15:48:42] <PCW> other than duplicates there should be just 8 signals:
[15:48:43] <PCW> +5V, GND, A,/A ,B,/B, Z,/Z
[15:49:00] <PetefromTn_> plus index
[15:49:10] <PCW> Z is index
[15:49:25] <PetefromTn_> oops sorry
[15:49:46] <PetefromTn_> Hang on lemme check the original cable to see how many it has. I recall it was missing one..
[15:50:24] <PCW> one may be shield ground
[15:51:28] <ssi> PetefromTn_: what?
[15:52:25] <PetefromTn_> yeah there are seven leads and the shielding.
[15:52:37] <PetefromTn_> so that won't work right..
[15:52:41] <PetefromTn_> ssi?
[15:52:53] <PCW> hmm that's not enough
[15:52:55] <PetefromTn_> I was just bustin your chops man...LOL
[15:54:36] <ssi> ah
[15:54:53] <ssi> PetefromTn_: I'm about to try making a little bookshelf box for the FE126En drivers
[15:54:56] <ssi> to see how it works out
[15:55:41] <PetefromTn_> Funny thing is the Milspec barrel connector that went into the side of the motor housing has ten pins on it. The sockets on the other side are solder cup but I would probably need to remove them from the rubber seal to be able to use them properly.
[15:56:17] <PetefromTn_> The other side of the plug is there still on the millhead waiting for the socket LOL
[15:56:44] <PetefromTn_> ssi That sounds like a cool first project. Nothing like milling something useful for the machine
[15:57:17] <ssi> not for the machine
[15:57:19] <ssi> speaker boxes
[15:57:24] <ssi> and it's not a first project :P
[15:57:45] <PetefromTn_> OOPs sorry I did not catch the speaker model number figured it was your stepper drivers LOL
[15:58:22] <PetefromTn_> That sounds like a great idea.
[15:58:38] <PetefromTn_> Do you have more than that one pair you put into the pensils?
[15:59:41] <ssi> I have five different pairs of fullrange drivers
[15:59:47] <ssi> all different models
[15:59:55] <PetefromTn_> Jeez man you kill me...
[16:00:11] <ssi> only two pair are in what I'd consider to be nice boxes
[16:00:36] <PetefromTn_> I need to get a nice pair and build those cool horns I was drooling over recently.
[16:01:02] <PetefromTn_> So many projects right now I am trying to get that Field Target Competition rifle working correctly.
[16:01:16] <PetefromTn_> Still have not gotten the shot cycle down where I want it and the speed is too slow.
[16:02:39] <ssi> I'm gonna try something goofy
[16:02:43] <ssi> make these interlocking
[16:02:59] <PetefromTn_> PCW It sure would be nice to be able to use that original cable for the new encoder. Would save me a lot of trouble.
[16:03:11] <PetefromTn_> you mean like a box joint?
[16:03:27] <ssi> not exactly
[16:03:36] <ssi> not nearly so many fingers
[16:03:42] <ssi> just a couple, to hold it together for glueup
[16:03:55] <PetefromTn_> what size are they gonna be?
[16:03:59] <ssi> I don't like gluing plywood edge grain directly to face grain
[16:04:05] <ssi> these are pretty small
[16:04:11] <ssi> http://www.fostexinternational.com/docs/speaker_components/pdf/FE126En.pdf
[16:04:14] <ssi> the bottom drawing
[16:04:16] <PetefromTn_> yeah you need fasteners..
[16:04:37] <ssi> don't want fasteners either
[16:04:42] <ssi> so I'm doing some LAZRJOINERY
[16:04:58] <PCW> 7 wires makes sense for a resolver ( 6 signals + shield ) but is too few fro a differential encoder
[16:05:01] <humble_sea_bass> doves?
[16:05:03] <PetefromTn_> you mean that little bass unit?
[16:05:59] <ssi> yes
[16:06:02] <PetefromTn_> Nothing wrong with fasteners you can dowel pin the holes once it is together and then sand and finish looks nice..
[16:06:31] <cradek> the resolver cabling I've seen has very obvious twisted pairs, shielded separately from each other
[16:06:40] <ssi> well I'm thinking maybe I'll build these so they interlock for glueup, then veneer them or something
[16:06:53] <PetefromTn_> sweet..
[16:07:22] <SpeedEvil> ssi: I've been thinking of that for making bits for the outside of my house
[16:08:20] <SpeedEvil> ssi: take a 2*4m panel - and on the long edge, cut out 1.2cm fingers every 5cm or so. With correspondeing holes in 2.4*0.1m boards going along the sides to make 'h' beams.
[16:08:23] <SpeedEvil> I even
[16:08:59] <SpeedEvil> Then concrete slabs (2cm thick) on the outside hung on brackets, and insulation on the inside.
[16:09:20] <PCW> I guess if you had that kind of cabling and the individual shields were isolated, they could be re-purposed as 5V and GND
[16:10:03] <ssi> SpeedEvil: neat
[16:10:49] <SpeedEvil> 12mm
[16:12:06] <SpeedEvil> Here I would link a video of a house completely made out of plywood boxes 1.2*2.4*0.3m or so, using a CNC router.
[16:12:15] <ssi> https://pbs.twimg.com/media/BxR8I8SIcAA9JTq.png:large
[16:12:18] <SpeedEvil> Unfortunately, the owners of the video don't make it available
[16:12:39] <ssi> biggest question is how it's gonna look with all that burnt edge grain peeking through :)
[16:12:58] <ssi> I'm going to do similar fingers between the top/bottom and sides
[16:13:07] <SpeedEvil> They basically took several hundred sheets ofply - and cut out a _lot_ of boxes - quick squirt of glue, nail together - done.
[16:13:25] <SpeedEvil> and then all the boxes clipped together (with windows and such pre-cut) into a house.
[16:13:33] <ssi> nice
[16:13:41] <SpeedEvil> ssi: sand the edges, the burn goes away
[16:14:08] <ssi> the burn might look cool actually
[16:14:10] <ssi> contralst
[16:14:14] <ssi> contrast even
[16:14:21] <ssi> I'm just gonna build one and see how it looks :)
[16:14:27] <SpeedEvil> good plan
[16:14:28] <ssi> starting with these little guys so i don't burn up too much plywood
[16:14:46] <ssi> but if I decide I want to sand away the burn, I'll make the tabs a bit too long and sand them flush
[16:14:54] <SpeedEvil> how large is your laser?
[16:14:55] <ssi> which is tough to do without burning through the top veneer of the plywood
[16:15:00] <ssi> FRICKIN HUGE :)
[16:15:03] * SpeedEvil is getting 100 sheets delivered soon
[16:15:11] <ssi> 24x48" working area, 100W
[16:15:13] <SpeedEvil> I really want to make a router that can take full sheets
[16:15:22] <ssi> yeah full sheets would be nice but I don't have the space for it right now
[16:16:47] <PetefromTn_> Yeah me too I want a 5x10 router here built from steel and heavy duty enough to do aluminum milling occasionally
[16:17:09] <PetefromTn_> PCW I need to check that cable to see if there are unused leads inside there that I can hookup.
[16:17:23] <ssi> one day one of the big hangars at the airport will open up and I'll snag it
[16:17:31] <ssi> I believe they're 100x80' with an 80' clear span
[16:17:41] <ssi> they're actually 200x80 with two doors, but they rent half at a time
[16:17:58] <ssi> 8000 sqft would be enough for me to put both planes and the whole machine shop comfortably
[16:18:20] <ssi> and then I won't have to worry about silly things like garage door height :)
[16:18:50] <Deejay> gn8
[16:19:25] <PetefromTn_> http://imgur.com/lJYvaZS Completed encoder mount. Just need some hardware now
[16:19:50] <SpeedEvil> ssi: handy.
[16:20:02] <SpeedEvil> ssi: you could make a 3d printer, and print houses with wheels on them
[16:20:03] <PetefromTn_> ssi Yeah man all you need is that immediately behind your house and you would be perfect
[16:20:44] <ssi> PetefromTn_: no, I need that at the airport, and to build a second level apartment in it, and sell the house
[16:20:55] <PetefromTn_> EXACTLY
[16:21:21] <PetefromTn_> I know I have seen people buy older commercial buildings and do exactly that build a home and offices above the shop.
[16:22:27] <PetefromTn_> BRB
[16:26:56] <ssi> https://pbs.twimg.com/media/BxR_ipACAAAlAGj.png:large
[16:26:58] <ssi> I think that'll work
[16:28:33] <PetefromTn_> WOW totally Awesome.. Guess what I just found out..
[16:29:27] <PetefromTn_> apparently the large cable that goes to the spindle motor for the resolver has EIGHT leads inside it plus a shielding and a small ground...
[16:29:48] <PetefromTn_> So they just used what they needed at Cincinatti and capped off the last lead.
[16:30:17] <PetefromTn_> This means I might be able to redo the cable to accept the new encoder without having to source a new cable. This is a heavy duty extremely well shielded cable
[16:30:48] <ssi> excellent
[16:31:00] <PetefromTn_> It has the wire shielding on the outside, then it has tinfoil type shielding inside of that. Then finallly each wire pair is shielded inside more tinfoil shielding
[16:31:55] <ssi> that's good stuff
[16:32:02] <PetefromTn_> Now I just need to figure out if I can remove the pins to the MilSpec Barrel connector so I can resolder them into both plugs.
[16:32:09] <PetefromTn_> or both ends rather.
[16:32:57] <PetefromTn_> I swear this machine has been a pleasure to work on everywhere I look it is very well put together and this is another example.
[16:35:31] <SpeedEvil> ssi: I assume you can't tilt the laser?
[16:36:13] <ssi> no
[16:37:31] <PCW> PetefromTn: if you have 3 twisted pairs, the A,/A B,/B and Z,/Z sets need to be paired
[16:39:00] <PetefromTn_> There are four twisted pairs in the cable. plus a shield and a thin wire ground it looks like.
[16:39:31] <PCW> OK so thats good
[16:41:03] <PetefromTn_> I guess it is. I need to find a way to disassemble this MilSpec Barrel connector to remove the pins and then I can start soldering everything together. The mount is completed finally and I just need the bolts and screws to get the whole thing installed.
[16:41:43] <SpeedEvil> ssi: no dovetails then :)
[16:41:45] <PetefromTn_> I am getting excited to finally have rigid tapping and maybe even toolchanger control here possibly soon. Damn that would be the cats ass!!
[16:42:02] <SpeedEvil> ssi: but the above - glued shoud be quite strong enough
[16:46:42] <PetefromTn_> Anyone have any suggestions for removing these pins from the barrel connectors without buying some expensive tool?
[17:11:29] <Tom_itx> PetefromTn_ what pins?
[17:11:35] <Tom_itx> a piece of brass tubing?
[17:13:57] <PetefromTn_> Yeah this is about an inch and a quarter diameter barrel plug with then pins inside it that I need to dismount to solder the new encoder leads onto. It is I am sure using those barbed pins that you typically use an insertion tool for but I don't have the cash right now for one.
[17:14:22] <PetefromTn_> I was thinking of trying to turn one from the tool steel I have here and then try to carefully use it to dismount the pins.
[17:14:42] <Tom_itx> those tools don't work that good anyway
[17:14:44] <PetefromTn_> The pins are pretty tiny
[17:14:45] <Tom_itx> i've got a couple
[17:14:57] <Tom_itx> at least the ones i have don't
[17:15:00] <PetefromTn_> look like 1/32 or so diameter
[17:15:25] <PetefromTn_> actually the barrel is probably just over an inch.
[17:15:59] <PetefromTn_> Yeah I used to use them in the Coast Guard on the C130 aircraft all the time. The tools work but are also kinda difficult to use.
[17:16:13] <PetefromTn_> Would still love to have the right one right now hehe
[17:17:58] <PetefromTn_> The bitch is that with these tiny thin pins the tool needs to be really thin also or it will tear the damn rubber seal.
[17:19:12] <ssi> SpeedEvil: yeah, dovetails aren't gonna work with a vertical beam sadly :)
[17:19:48] <ssi> PetefromTn_: I have tools for that stuff
[17:20:43] <PetefromTn_> REALLY?
[17:20:48] <ssi> probably :P
[17:20:57] <PetefromTn_> you're my hero man!
[17:21:06] <PetefromTn_> I'm not worthy!
[17:21:08] <ssi> well don't get too excited yet
[17:21:20] <PetefromTn_> I grovel at your sandals..!!
[17:21:36] <ssi> http://www.dmctools.com/Products/installing_removal_tools.html
[17:21:38] <PetefromTn_> You are a GIANT among men!
[17:21:41] <ssi> I have a wide variety of those
[17:22:19] <ssi> most of them are down at the airport
[17:22:44] <PetefromTn_> Do they work for removing the MilSpec Barrel Connector pins?
[17:23:00] <ssi> got an MS number?
[17:23:08] <ssi> there's lots of different barrel connectors :)
[17:24:59] <PetefromTn_> not really but just measured the pins they are 1/16" diameter and there are ten in a housing that measures 1.140 across the threads on the outside
[17:25:19] <PetefromTn_> ten pins in the connector
[17:26:31] <ssi> send me a picture
[17:30:24] <PetefromTn_> http://imgur.com/DbgbEsO,nMq31i6 http://imgur.com/DbgbEsO,nMq31i6#1
[18:20:30] <jdh> plenty of room to solder in there.
[18:26:05] <PetefromTn_> jdh?
[18:26:36] <jdh> yes?
[18:26:55] <PetefromTn_> what are you talking about?
[18:26:59] <jdh> why take the pins out
[18:27:34] <PetefromTn_> Oh because I think if you try to solder with them installed you wind up melting the rubber seal and mounting area
[18:27:43] <jdh> wuss
[18:27:55] <PetefromTn_> yeah you know me right...
[18:27:58] <jdh> little flux, go in quick.
[18:35:58] <PetefromTn_> Honestly I would rather just try to machine a little extraction tool and not worry about screwing up the only one I have here. I am sure you could probably do it the way you are suggesting tho.
[18:39:09] <ssi> oh those are solder cup pins
[18:39:13] <ssi> I don't think they come out
[18:39:27] <PetefromTn_> huh?
[18:39:42] <ssi> the crimp ones are insertion
[18:39:47] <ssi> I don't think the solder cup ones are
[18:42:21] <PetefromTn_> hrm
[18:44:00] <PetefromTn_> I will try one. I can get the encoder cables seperated from the ribbon cable and thread it thru the dust cover and into this connector. Then once I am ready to install I can just tension the ribbon cable to clear the aperture wheel.
[19:42:00] <jdh> I have some similar connectors that separate and the pins just fall out.
[19:42:11] <jdh> but, they are crimp pins
[20:51:48] <PetefromTn_andro> Evening folks
[20:52:11] <XXCoder> hey
[20:55:32] <PetefromTn_andro> Hey code
[20:56:44] <PetefromTn_andro> Just bought a kickass tee shirt at the mall. It's got a cool skulll
[20:56:52] <XXCoder> skull lol
[20:56:53] <PetefromTn_andro> Makes me smile LOL
[20:57:09] <PetefromTn_andro> If I can five
[20:57:37] <PetefromTn_andro> Figure out how to attach pics from this phone I'll show ya hehe
[20:57:56] <XXCoder> easy, upload to pastebin or something
[20:58:36] <CaptHindsight> I was going to make motorcycle jackets like that but it would tie into the brake and turn signals so the eyes would flash as turn and brake signals
[21:00:33] <PetefromTn_andro> Sweetness!!
[21:00:34] <XXCoder> lol
[21:00:36] <XXCoder> yeah
[21:00:50] <XXCoder> not much into skull stuff but can make lots stuff cool
[21:09:04] <PetefromTn_andro> Okay downloading photobucket app now.
[21:12:48] <PetefromTn_andro> http://i150.photobucket.com/albums/s83/matospeter/Mobile%20Uploads/IMAG0068_zps3orltb16.jpg
[21:14:06] <XXCoder> why not this skull http://i.crackedcdn.com/phpimages/article/4/3/8/59438.jpg?v=1 lol
[21:14:20] <XXCoder> close up https://skullsproject.files.wordpress.com/2012/04/2344695_1_l1.jpg
[21:19:28] <PetefromTn_andro> Back again ;)
[21:19:40] <XXCoder> wb
[21:19:45] <XXCoder> did you see my links
[21:21:35] <PetefromTn_andro> No lost it chatting to New Zealand on viber at the same time here with a friend and goofed hehe
[21:21:52] <XXCoder> ok a sec
[21:21:55] <XXCoder> why not this skull http://i.crackedcdn.com/phpimages/article/4/3/8/59438.jpg?v=1 lol
[21:21:57] <XXCoder> close up https://skullsproject.files.wordpress.com/2012/04/2344695_1_l1.jpg
[21:22:55] <PetefromTn_andro> Hehe that's cool did you see my tee shirt?
[21:23:01] <XXCoder> yeah
[21:23:13] <XXCoder> skulls isnt really my thing but its nicely done
[21:23:46] <PetefromTn_andro> Yeah I'm not a skull head either....well actually I guess I am LOL
[21:24:16] <tjtr33> CaptHindsight, for the new RTAI for LinuxCNC, is this suitable? http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=8994569&CatId=5138
[21:24:24] <PetefromTn_andro> I play with Airbrushing and skulls are a common theme
[21:25:38] <XXCoder> yeah I wonder why
[21:25:58] <XXCoder> and everyone is just meat covered skellies lol
[21:26:50] <PetefromTn_andro> I don't know what the fascination is either but I thought that tee shirt looked wicked cool
[21:27:32] <PetefromTn_andro> It was only like ten bucks so I had to have it. I tear up tee shirts quickly usually
[21:29:27] <PetefromTn_andro> I did order up some tooling for this prototype job today. I also got a new er32 collet or two
[21:30:09] <PetefromTn_andro> Got them from MSC so hopefully they will be here tomorrow or Saturday
[21:31:11] <CaptHindsight> tjtr33: never tested a Turion 64 X2
[21:31:37] <CaptHindsight> tjtr33: I wish they gave the actual part #
[21:32:06] <CaptHindsight> tjtr33: http://www.dailydot.com/politics/internet-slowdown-fcc-net-neutrality/
[21:34:02] <tjtr33> CaptHindsight, i dont think many noticed the battle for the net. I saw the widgets on a few sites, like InternetArchives. I ask here, no response.
[21:36:27] <tjtr33> spent the day at IMTS, its overwhelming. more puma's than i could count. and Renishaw mini CMMs all over the place http://www.renishaw.com/en/equator-the-versatile-gauge--13465
[21:38:44] <PetefromTn_andro> Damn I bet that is a great show. I have been to one before. Amazing stuff
[21:42:07] <tjtr33> they were gluegunning a car. a full sized car, using a thermwood router for a machine tool. maybe 2meters by 3 meters by 1.5 meters stroke
[21:43:51] <PetefromTn_andro> The thermwood machines are pretty sweet they make a damn good cnc router. They had a massive five axis machine on display making a circular stairway from solid laminated wood when I was there.
[21:44:44] <PetefromTn_andro> I really need to build a nice big flatbed cnc router for myself.
[21:45:04] <tjtr33> i looked at Wele/Toyoda & Breton too, SNK was the biggest there, scary to see the head rush at you form down a carwash sized tunnel
[21:46:36] <PetefromTn_andro> Breton looks like some quality stuff no? I recall watching a YouTube video with an impressive five axis with rotary table
[21:47:04] <PetefromTn_andro> At least I thought it was a Breton
[21:48:42] <tjtr33> yeah, but it cost like 1.4M$ the guy that wanted had quite a bit less to spend
[21:48:58] <XXCoder> jeez
[21:49:01] <tjtr33> the big stuff seems like its Italian http://www.breton.it/machinetool/commons/thumbs/995x390_35413.jpg
[21:49:23] <tjtr33> i thinks thats an airplane fuselage in the mill
[21:49:28] <PetefromTn_andro> Gotta pay to play I guess
[21:50:24] <tjtr33> dang microwave just blew up, half baked pizza, yek
[21:50:39] <PetefromTn_andro> Dunno what the Hell you would be milling on the outside of a plane fuselage. Maybe measuring?
[21:51:03] <PetefromTn_andro> Literally blew up?
[21:51:33] <tjtr33> yeh its pop sizzle fizzing right now
[21:51:53] <PetefromTn_andro> Damn that sux..
[21:52:09] <PetefromTn_andro> Did it have aluminum sheet underneath it LOL
[21:52:27] <tjtr33> im trying to save the pizza, the convection/microwave is a loss
[21:52:37] <tjtr33> was convection mode
[21:53:04] <PetefromTn_andro> Save the pizza man by all means necessary hehe
[21:53:29] <XXCoder> fork?
[21:53:56] <PetefromTn_andro> That's probably what he said when it exploded
[21:54:58] <XXCoder> Did you go Tim the Tool man?
[21:55:42] <tjtr33> didnt see that, but i only covered the north bldg today
[21:57:11] <PetefromTn_andro> I remember when I was there we got to see and meet Norm Abrams from the New Yankee Workshop.
[21:58:05] <PetefromTn_andro> Being a long time pro woodworker that was kind of like meeting Babe Ruth or something heh
[21:59:21] <XXCoder> lol cool
[21:59:23] <tjtr33> i picked up one good freebee. at IGUS they had a tool to quick open the cable carriers
[21:59:57] <PetefromTn_andro> Well goodnight folks I'm getting tired. Cya tomorrow.
[22:00:03] <tjtr33> gnite
[22:00:15] <PetefromTn_andro> Nite
[22:06:23] <tjtr33> CaptHindsight, is this cpu familiar? tiger has an Athlon II, processor number B22, interface LGA775
[22:10:04] <CaptHindsight> ? LGA775 was an Intel socket http://en.wikipedia.org/wiki/LGA_775
[22:10:46] <CaptHindsight> has Tiger Direct been taken over by Chinese ebay product description writers?
[22:13:10] <XXCoder> yes. and no. and yes
[22:25:51] <tjtr33> hahaha yeh you're right
[22:29:54] <tjtr33> gnite
[23:05:02] <HailDraft> hello dose any one have any experience running linuxcnc on a single board computer with a pci slot? any ideas, suggestions or recomended reading would be much apreciated
