[00:11:07] <Cromaglious_> yep gonna need 123 blocks to clamp this receiver down
[00:12:06] <Cromaglious_> hmmm need to load up fusion on the windows machine tomorrow, and see if I can generate some gcode...
[00:39:04] <Cromaglious_> 4 blocks ordered... $22 2 blocks would have been $16
[00:40:17] <LeelooMinai> I keep watching CAM videos and seems eveyone uses expensive machinist vises:/
[00:40:55] <Cromaglious_> I have a 3040... I only have 70mm of clearance
[00:41:39] <Cromaglious_> as it is.. I'm gonna have to mod one block to have to spots for clearance around the selector stops
[00:41:43] <LeelooMinai> Right, I guess they will add like 2 inches from the base
[00:43:02] <Cromaglious_> I can clamp a 1-2-3 2x3 side down. Bolt a 1x2 side down against the 1st block, then clamp the receiver to the second block
[00:43:35] <Cromaglious_> and use a 3rd block as a clamping face on the other side
[00:43:57] <Cromaglious_> and clamp the 4th down to the bed as well
[00:44:52] <LeelooMinai> Hmm, why 1-2-3 blocks? I have this clamping set - it has something called step blocks and I though those are used to clampt things to the table.
[00:45:23] <Cromaglious_> gonna have to make a spacer the width of the receiver to go in the trigger guard maybe a 0.001" bigger
[00:46:26] <Cromaglious_> 0.875" so make it 0.876"
[00:47:47] <roycroft> use the clamping set to clamp your 1-2-3 blocks down
[00:49:35] <Cromaglious_> I can stick a 1/4-20s bolt into the table and using hold downs bolt the 1-2-3 down. I can use a piece of 1/2 all thread to go through all 4 blocks to clamps them all together
[00:49:51] <Cromaglious_> going thru the trigger guard.
[00:50:20] <Cromaglious_> I have less than 0.020" from the bit to the top of the receiver.
[00:51:20] <pink_vampire> don't use the dremel slitting saw
[00:51:42] <Cromaglious_> I could get another 0.30mm clearance.. setting home a -0.030mm
[00:51:49] * LeelooMinai imagines pink_vampire typing this with 9 fingers
[00:51:50] <Cromaglious_> 400w er11 collet
[00:52:03] <pink_vampire> no
[00:52:10] <Cromaglious_> 3040 engraver
[00:53:19] <Cromaglious_> it's what I got
[00:53:48] <pink_vampire> instead of cutting the material it cut the screw that hold the blade
[00:54:09] <Cromaglious_> hehe... I believe it
[00:55:00] <pink_vampire> and now i need to trim 4 m3 screws and i have no functional mandrel
[00:57:55] <LeelooMinai> I don't trust Dremel-anything. For my electronics works and minor stuff I use Proxxon tools - they are pretty nice
[00:58:06] <LeelooMinai> Not that expensive too
[00:58:40] <roycroft> i can't afford dremels
[00:58:42] <roycroft> they burn up too fast
[00:58:56] <roycroft> i have a fordom flex-shaft tool, and it is great
[00:59:37] <roycroft> i probably spent $500 on dremels before i broke down a few years ago and spend $250 on the fordom
[00:59:46] <roycroft> and years later it still works like it was brand new
[01:01:25] <Cromaglious_> I don't get that small...
[01:01:47] <Cromaglious_> I tend to use die grinders with 1/4 collets
[01:02:00] <roycroft> i use die grinders for high speed tooling
[01:02:17] <roycroft> they're pretty noisy though
[01:02:25] <roycroft> and they get really cold after a few minutes
[01:07:07] <roycroft> i am pleased
[01:07:26] <roycroft> i made some brackets to attach some fiber optic cable raceways to some powder coated equipment racks
[01:07:44] <roycroft> i found some rustoleum paint that said it left a "fine textured finish"
[01:07:48] <roycroft> so i gave it a go
[01:07:56] <roycroft> and it really looks a lot like powder coating
[01:08:06] <roycroft> it should match the racks nicely
[01:08:57] <roycroft> i considered having the brackets powder coated for a really good match, but didn't want to wait for that to be done
[01:09:17] <roycroft> turn-around time on powder coating is about a week here, under the best circumstances
[01:10:27] <roycroft> plus, the paint cost me $5.76, and powder coating would have cost at least $50
[01:10:37] <roycroft> time was more of a concern than cost though
[01:19:12] <Cromaglious_> powder coating to me is more of a buzz word finish than actual finish.. I'd rather have a good paint job.
[01:20:28] <Cromaglious_> I've peeled too many powder coat coverings off..
[01:20:54] <Cromaglious_> and found rust underneath
[01:25:19] <CaptHindsight> the polymers are similar
[01:27:44] <CaptHindsight> one just melts and crosslinks, the other requires the solvent to evaporate and the catalyst to speed the crosslinks
[01:29:14] <CaptHindsight> powder coating if properly applied properly is also much thicker
[01:36:58] <CaptHindsight> one too many properlys in that last sentence
[01:37:52] <antipsychiatry> Hi. Read : http://www.naturalnews.com/049755_Bride_of_Frankenfood_Hillary_Clinton_Monsanto.html
[02:23:52] <Deejay> moin
[02:30:08] <JesusAlos> morning
[04:39:39] <XXCoder> naturalnews lol
[04:51:50] <pink_vampire> hi XXCoder
[04:51:56] <XXCoder> hey
[04:52:14] <pink_vampire> the edm z axis is done
[04:52:31] <XXCoder> nice
[04:53:34] <pink_vampire> now i need some how to fit the drill chuck
[04:53:34] <pink_vampire> and i saw that on the back of it there is a thread
[04:55:08] <XXCoder> yeah?
[04:55:12] <XXCoder> figuring to mount it on eh
[05:08:22] <XXCoder> so once edm is done whats your plan with it
[05:27:06] <jthornton> morning
[05:28:09] <XXCoder> yo
[05:46:44] <Deejay> lunch time ;)
[05:46:58] <XXCoder> no thanks just had my dinner
[05:48:13] <jthornton> waiting on my slice of cheese for breakfast
[05:53:02] <XXCoder> srastic bastard http://cdn.twentytwowords.com/wp-content/uploads/7milk1.jpg?23a5cb
[05:55:07] <jthornton> my buddy from Louisiana said 60,000 homes were flooded and the trash is unreal
[05:56:41] <jthornton> https://ibin.co/2tS5SGIDXEHh.jpg
[06:00:49] <XXCoder> sucks
[06:00:59] <XXCoder> weather is permently changed
[06:01:05] <XXCoder> it wont improve
[06:01:38] <jthornton> that's the view down his fathers street
[06:01:56] <_methods> permanently changed...........
[06:02:15] <_methods> pretty sure as long as this ball of rock has existed the weather has been changing
[06:02:29] <jthornton> yep
[06:02:45] <jthornton> very slowly by our time measures
[06:02:48] <XXCoder> well yes and no
[06:02:57] <XXCoder> this epoch is new one
[06:03:27] <_methods> don't believe the hype
[06:03:35] <XXCoder> while start time is pretty vage, from hundred years ago to around now, but name is now Anthropocene epoch
[06:03:46] <XXCoder> I dont belive or disbelive
[06:06:38] <SpeedEvil> jthornton: Louisiana - Bangladesh 2.0
[06:07:05] <_methods> tends to happen when you live below sea level lol
[06:08:01] <XXCoder> im lucky enough to live pretty surpising high above sea level, when I can literally walk to inlet sea, which is basically ocean
[06:11:57] <XXCoder> well night all
[06:36:10] <Tom_itx> morning
[06:53:54] <jthornton> morning
[07:17:37] * jthornton is having fun with getattr and setattr in Python
[07:19:03] <jdh> my house is 19ft asl
[07:25:37] <_methods> yeah i think i'm only like 74ft asl
[07:28:26] * skunkworks_ isn't in the asl club
[07:31:38] <_methods> make sure you got flood insurance lol
[07:33:05] <jthornton> sea level doesn't mean much when you live in the hills but creek rising has meaning
[07:41:16] * jthornton really hates the gtk3 file chooser
[07:41:35] <skunkworks_> ah
[07:42:41] <skunkworks_> I am 738' above sea level but about 40ft above the Mississippi..
[07:47:36] <gregcnc> that 5axis router i linked the other day https://www.instagram.com/p/BJwyKF5AM44/
[07:49:13] <jthornton> I'm 361' plus some and about the same above the Mississippi
[08:29:28] <skunkworks_> http://electronicsam.com/images/house/view3.JPG
[08:37:03] <CaptHindsight> FinboySlick: back for a few minutes
[08:40:27] <FinboySlick> CaptHindsight: let's PM since it's entirely off topic.
[08:56:49] <archivist> jdh but...asl is arithmetic shift left :)
[08:57:07] <archivist> did the earth move for you?
[08:58:44] <jdh> skunkworks: train tracks on the riverbank?
[08:59:46] <skunkworks_> yes
[09:02:43] <skunkworks_> American sign language
[09:11:37] <CaptHindsight> skunkworks_: you have actual hills
[09:14:45] <skunkworks_> it is the coulée region...
[09:49:56] <pink_vampire> hi
[09:55:40] <Simonious> \o
[09:58:18] <pink_vampire> Simonious: ?
[09:58:24] <Simonious> o/
[09:58:30] * Simonious waves
[09:58:43] <Simonious> = arm o = head
[09:58:48] <Simonious> \ = arm
[10:04:04] <FinboySlick> o= is a zombie reaching for your brain then?
[10:05:14] <Simonious> works for me..
[10:05:19] <Simonious> o_
[10:05:23] <Simonious> seems closer
[10:05:34] <Simonious> but I wasn't thinking overhead view
[10:34:07] <MacGalempsy> morning
[10:43:09] * archivist demands a vote for afternoon
[10:45:01] <MacGalempsy> archivist: a vote for what?
[10:46:00] <archivist> the Greenwich meridian being not far from me makes it afternoon, you are late!
[10:50:03] <MacGalempsy> oh, so you would rather me say good XX:xx +nGMT?
[10:50:48] <CaptHindsight> use metric time
[10:50:49] <archivist> :)
[11:05:09] <pink_vampire> http://i.imgur.com/gnpwDmz.png
[11:08:00] <MacGalempsy> Let me rephrase that Good 4:40 GMT
[11:09:06] <archivist> time for afternoon coffee (and cake)
[11:09:21] <Simonious> almost time for the morning workout
[11:09:31] <skunkworks_> don't you mean biscuit?
[11:09:40] <skunkworks_> and tea?
[11:09:48] <Simonious> well, I did just have chocolate milk and donuts..
[11:09:59] <archivist> tea tastes like plants
[11:10:48] <MacGalempsy> mmm donuts
[11:11:17] <archivist> I did like dunkin donuts while over there
[11:12:56] <_methods> now you know why we all fat
[11:13:06] * Simonious is NOT fat
[11:13:36] <_methods> it's ok we still get all the medals at the olympics
[11:14:05] <Simonious> I'll get a picture ... later today, in the gym or something
[11:14:06] <MacGalempsy> after a lifetime of donut consumption, usually the best shops are asian operated.
[11:14:13] <MacGalempsy> not corporate
[11:14:38] <archivist> actually per population percentage we got more medals
[11:21:15] <CaptHindsight> we kicked your bum in two wars and had to bail you out in another :)
[11:22:57] <_methods> hehe
[11:36:28] <MacGalempsy> so the drill press is 460v AC, so I am going to use a transformer to go from 230v to 460v single phase, then use a VFD
[11:36:44] <MacGalempsy> any suggestion on sizing the VFD for a 2 speed motor?
[11:38:07] <archivist> not all two speed motors will play nice with VFDs
[11:39:32] <MacGalempsy> it is a wilton strands and I am looking at the allen bradley 1305 vfd
[11:40:30] <MacGalempsy> how would I tell if it will work?
[11:40:53] <archivist> I dont know the motor, nor the vfd, I do know my motor on the schaublin did not play with a vfd
[11:42:09] <MacGalempsy> I am torn between getting a rotory phase convertor, to just use it with the factory gearbox,, and a vfd for finer speed control
[11:42:28] <archivist> I would use it as one speed and supply it with its full rated voltage, cannot rewire star to delta to change voltage
[11:43:27] <MacGalempsy> the rotary phase converter is 3x more than the vfd
[11:44:36] <archivist> get an inverting vfd so it has the right output volts or transformer then vfd
[11:44:57] <MacGalempsy> that is what I was thinking a transformer then vfd
[11:45:20] <MacGalempsy> single phase stepup to 460v then vfd
[11:45:32] <pink_vampire> http://www.ebay.com/itm/Gear-Stepper-Motor-DC-5V-4-Phase-Step-Motor-Reduction-Step-Motor-For-Arduino-TR-/400945178368?hash=item5d5a31e700:g:XVUAAOSwPcVVjVBA
[11:45:55] <pink_vampire> someone here used this motor?
[11:47:05] <MacGalempsy> nope. you may try the reprap channel
[11:52:20] <archivist> MacGalempsy, I went round to my local motor rewind shop to ask about vfd on a 2 speed, was not confident in his reply :)
[11:53:02] * MacGalempsy is reading an artcle on mating vfds to existing motors
[12:19:53] <gregcnc> what a workshop! http://www.missiseipi.com/105794847
[12:25:42] <archivist> no swarf does he make anything
[12:45:30] <ctjctj_> In theory I should be able to have two digital inputs that are probes. One NC and one NO?
[12:50:06] <Simonious> see, not fat: https://goo.gl/photos/HAfu1QcGbQxG4k9b7
[12:50:09] * Simonious chuckles
[12:50:36] <MacGalempsy> you could just have a skinny face
[12:50:48] <Simonious> Huh, good point
[12:50:53] <Simonious> I've known a few like that.
[12:50:55] <Simonious> Alright..
[12:51:03] <ctjctj_> something like loadrt or2; or2.0.in0 parport.0.pin-13.in-not; or2.0.in1 parport.0.pin-14.in; or2.0.out probe-in
[13:06:37] <Simonious> https://goo.gl/photos/gnEuBURDVGqDxwRq9 so there. Not fat
[13:11:29] <MacGalempsy> lol. you had to go and take the selfie in the gym
[13:12:00] <Flipp_> anyone have experience turning 6061? newb-ish machinist here looking for some tips on avoiding spaghetti/birds nests :(
[13:13:25] <pink_vampire> Simonious: I like the way you look
[13:18:38] <archivist> Flipp_, lathe or mill? you can use chip breaker inserts
[13:18:43] <MacGalempsy> sounds like a cnc match mate in heaven
[13:18:50] <MacGalempsy> well, finally making chips today
[13:19:06] <Flipp_> archivist: lathe. I'm using this insert: http://www.shars.com/files/products/404-1051/404-1051G.jpg
[13:19:31] <plpower> hi
[13:20:10] <archivist> anyway a bit of string flying past your ears is a right of passage into the machining world :)
[13:20:21] <Flipp_> archivist: I'm seeing the aluminum weld itself to the insert, causing it to dull, which in turn makes the strings
[13:20:58] <Flipp_> archivist: oh I'm sure :) I'm well aware I'm a crappy, neophyte machinist :)
[13:21:09] <archivist> lubrication to stop built up edge and use the correct speeds and feeds
[13:21:10] <Flipp_> but hoping to get better :)
[13:21:31] <plpower> Flipp_: is it a T6
[13:21:56] <gregcnc> ah any coating with aluminum in it is going to be sticky. Use uncoated insterts.
[13:22:16] <archivist> or hss :)
[13:22:18] <gregcnc> polished is even better
[13:22:24] <pink_vampire> Flipp_: I don'r have a lathe but I'm using 6061 and 2024-t3 on my mill.
[13:22:44] <gregcnc> HSS if you like sharpening tools
[13:22:47] <Flipp_> it's 6061 T6511
[13:22:58] <Flipp_> I don't mind HSS, but I get death spirals from them
[13:23:09] <archivist> very sharp tooling which standard carbide is not, ground and polished inserts
[13:23:10] <pink_vampire> the 6061 is more sticky to the cutter, and i'm using 4 flutes to compensate on the slow spindle that I have
[13:23:12] <Flipp_> I don't know how to grind a proper chip breaker :(
[13:23:56] <SpeedEvil> archivist: woo. http://i.imgur.com/BYVIgXX.jpg
[13:23:57] <plpower> use it on the tool
[13:24:07] <Flipp_> I'd prefer HSS since a) they're cheaper and b) I don't mind grinding (hey, I should get better at it anyway, heh)
[13:24:15] <gregcnc> http://www.shars.com/products/indexable-cutting/indexable-inserts/dcgx-21-51-lh-yd101
[13:24:25] <Flipp_> but if HSS is a lost cause on a lathe, I'm cool with inserts
[13:24:26] <SpeedEvil> archivist: bubble intact, seems in good shape.
[13:24:46] <plpower> live from Burningman https://www.youtube.com/channel/UCfVAyiqfH6gUq5FwzfoP2YA/live
[13:24:50] <archivist> SpeedEvil, if the price is right :)
[13:25:12] <pink_vampire> http://i.imgur.com/gnpwDmz.png - on the left part you can see wall thickness of 0.2mm 3mm tall
[13:25:21] <pink_vampire> right*
[13:25:24] <Flipp_> gregcnc: thanks. yeah, that was the one I was eyeing. is there a chart somewhere of insert coatings vs material?
[13:25:42] <archivist> SpeedEvil, it that the one of fleabay I pointed at?
[13:25:59] <gregcnc> any of the big name suppliers will explain insert geometry and coatings
[13:26:42] <pink_vampire> Flipp_: what is your issue?
[13:26:44] <ctjctj_> Flipp_, when you start getting birds nests AND you are using a tool with a chip breaker, then you need to experiment with speeds and feeds. For me the fix is often a larger DoC. But that is on a big(ger) manual lathe.
[13:26:46] <Flipp_> gregcnc: thanks :)
[13:27:28] <ctjctj_> Flipp_, shar inserts are not at the top of my list as well. Are you running any cooling?
[13:27:49] <SpeedEvil> archivist: well, pic is of it on my bed, and no buyers remorse :)
[13:27:51] <Flipp_> ctjctj_: yeah, I'm working on a tiny HF 7x10. Making it as rigid as I can, but a wet noodle would almost put its rigidity to shame :/
[13:28:00] <plpower> im off
[13:28:02] <archivist> SpeedEvil, good :)
[13:28:10] <SpeedEvil> archivist: yes
[13:28:13] <gregcnc> some 6061 simply won't chip unless you run crazy CNC speeds and coolant
[13:28:18] <ctjctj_> Flipp_, my lathe is a SB 5'x13" so a little larger.
[13:28:21] <pink_vampire> Flipp_: huge advice return it
[13:28:41] <MacGalempsy> here is what I am cutting today. https://www.flickr.com/photos/58181938@N03/29332403376/in/dateposted-public/
[13:28:54] <Flipp_> pink_vampire: mostly birds nests. can't figure out how to grind a good chip breaker in HSS, and I'm getting aluminum welding itself to my inserts when I try carbide
[13:28:56] <MacGalempsy> setup1 is just removing a bunch of material
[13:29:16] <ctjctj_> Flipp_, using an insert designed for aluminum will also help. Having said that I fight 6061 whenever I use a tool without a chip breaker.
[13:29:18] <MacGalempsy> how about a smaller cut?
[13:29:36] <archivist> Flipp_, that welding is called built up edge, lubrication/geometry
[13:29:38] <Flipp_> pink_vampire: I would, but I got it free second-hand from a friend. I'm just learning, so I don't mind the crappy-ish build quality
[13:30:01] <pink_vampire> I had the HF lathe, it's pure junk - too much play
[13:30:08] <ctjctj_> Flipp_, if you are getting work welding then you need to consider cooling. Start spraying it with WD40 as a first go.
[13:30:19] <pink_vampire> and you need to super close the gibs to make it functunal
[13:30:52] <Flipp_> ctjctj_: I was trying Tap Magic that I had lying around, but that didn't seem to help much. work still heated up quite a bit O.o
[13:31:22] <ctjctj_> Flipp_, Tap Magic for Al does not do nearly as well. WD-40 is a good cutting oil for 6061.
[13:31:27] <Flipp_> pink_vampire: yeah, I've spent an awful lot of time tuning/removing slop at the gibs, the ways, removed the compound when it's not needed, etc
[13:31:33] <Flipp_> ok, thanks. I'll switch to that
[13:31:39] <pink_vampire> about the weld, you basically need to lower the temperature of the chip. try to reduce the speed
[13:31:49] <ctjctj_> When I need to keep it cool tough I use a Noga Mist spraying soluable oil. Trim something or other.
[13:32:10] <SpeedEvil> Or increase the temperature so it comes off molten.
[13:32:11] <ctjctj_> Flipp_, and slow things down if you are getting work welding.
[13:32:23] <SpeedEvil> *(may not be a good idea)
[13:32:29] <pink_vampire> try very light cut
[13:32:30] <ctjctj_> SpeedEvil, I've not heard that one. Is this my leg coming off in your hands?
[13:33:17] <SpeedEvil> ctjctj: it seems like the sort of idea that might work sometimes, and most of the time result in insurance claims.
[13:33:41] <Flipp_> ctjctj_/pink_vampire: that's what was confusing me... SnF says it should be ~2-3x what I was using and still seeing welding
[13:33:50] <ctjctj_> Flipp_, speeds and feeds is magic. After three years I'm still just learning. You are fighting a lot of things when you are playing with speeds and feeds. The lighter the cut, the less stress, the less heat the longer the tool last but it takes longer to get anything done.
[13:33:55] <gregcnc> if using the right insert
[13:34:02] <pink_vampire> Flipp_: you need to feel it
[13:34:18] <Flipp_> ctjctj_: yup. I've only been doing this a month or so, so I'm still super new at it :)
[13:34:18] <pink_vampire> start with very slow and light cut
[13:34:23] <ctjctj_> If you are using inserts then the chip breakers only work well if you have the right DoC.
[13:34:36] <ctjctj_> Flipp_, at your stage, slow it down.
[13:34:48] <pink_vampire> then spin it faster and take light cut.
[13:35:21] * archivist watches all the conflicting advice
[13:35:22] <pink_vampire> also you need to make sure that your cutter is not too high / low and in the right angle.
[13:35:27] <ctjctj_> Use that WD-40. For me it does lots to remove the work welding.
[13:35:42] <ctjctj_> archivist, I don't think it is conflicting.
[13:35:55] <archivist> wd-40 or parrafin
[13:36:49] <Flipp_> pink_vampire: yup, I'm using the bump-a-thin-shim-and-make-it-vertical-against-tool-steel trick to dial in the height
[13:37:12] <Flipp_> pink_vampire: I'm wondering if my 0xA tool holders are actually tilting the tools a bit :/
[13:37:16] <ctjctj_> Flipp_, you can go to most local hardware stores and get WD-40 by the gallon. Get a WD-40 spray bottle and don't worry about too much. Too much is almost never a problem.
[13:37:48] <Flipp_> archivist: haha, yeah, I just figure the more detail the better... I'm sure there's at least some signal in the noise :D
[13:37:51] <ctjctj_> Flipp_, try facing the end to set your tool height.
[13:38:07] <Flipp_> ctjctj_: got a big 'ol can of it, and put some of it in a misting bottle :)
[13:38:25] <gregcnc> I cut 6061 dry with uncoated Sandvik CCGX inserts all the time, as light or deep a cut as I want. Sometimes it chips other times not so much.
[13:38:29] <Flipp_> ctjctj_: I've tried that too... didn't know if that was a better/worse way
[13:39:08] <gregcnc> if you don't want WD40 stinking up the shop, odorless kerosene or lamp oil
[13:39:17] <Flipp_> gregcnc: yeah, I'm using a coated SDJC insert, which is probably my first problem
[13:39:41] <ctjctj_> Flipp_, facing is a very good way once you learn to read it. If you git a nipple on the end your height is wrong. Lower the tool below center, face again. Raise a little, rinse and repeat till it is right on. Soon you'll be able to read the pip/nipple and know which way to adjust.
[13:39:43] <MacGalempsy> my machine uses a heavy cutting oil, and that stuff is MESSY
[13:39:45] <Flipp_> ctjctj_: if the WD40 smokes, is that a sign?
[13:39:57] <gregcnc> no
[13:40:04] <MacGalempsy> yes, a sign that physics still works
[13:40:10] <archivist> a sign you can us for communication
[13:40:10] <Flipp_> ok, just making sure that wasn't a "it's too hot, slow down" or something
[13:40:13] <ctjctj_> Flipp_, it means your work is hot. Not a problem IF it is not welding.
[13:40:18] <Flipp_> archivist: smoke signals!
[13:40:33] <Flipp_> thanks for the tips. got some stuff to work with tonight :)
[13:40:38] <ctjctj_> The physics says that converting from a liquid to a gas (Smoking) takes a bunch of heat out of the system.
[13:40:42] <Flipp_> yup yup
[13:41:05] <Flipp_> didn't know if it being smoking meant the work was getting close to the WD40 the flash point
[13:41:05] <ctjctj_> So when it is smoking it is working. If it is burning, see SpeedEvil
[13:41:13] <Flipp_> haha
[13:41:30] <Flipp_> oh, one other thing: any tips on grinding a chip breaker into HSS?
[13:41:41] <ctjctj_> Flash point on cutting oils is higher/much higher than the smoking point.
[13:41:43] <ctjctj_> On purpose.
[13:42:06] <ctjctj_> Flipp_, go find some videos by "Abom79" on youtube for grinding HSS tool bits.
[13:42:47] <Flipp_> ctjctj_: yup. I just know that WD40 isn't exactly designed as a cutting oil, so wanted to be sure
[13:42:56] <ctjctj_> The best I've done is none too great. Though I do have a shearing tool that leaves a beautiful finish. Takes 1 to 2 thousand per pass and leaves a nearly mirror finish.
[13:43:57] <ctjctj_> Flipp_, the only thing that I think wd-40 is good for is squeeky door hinges and AL cutting oil. And only when I'm too lazy to get out my noga mist.
[13:44:30] <Flipp_> haha. I'll be sure to get a misting setup after I build my garage and upgrade from this HF toy :)
[13:44:31] <djdelorie> wd40 is just kerosene and paraffin, yes?
[13:44:34] <DaViruz> it's only good for hinges for a day or so
[13:44:50] <djdelorie> vaseline for door hinges
[13:44:51] <gregcnc> mostly stoddard solvent and some oil
[13:45:05] <Flipp_> lithium grease works well on doors :)
[13:45:09] <Flipp_> thanks for the tips all!
[13:45:27] * djdelorie has some kerosene but not willing to bring it to the smoke point :-)
[13:45:42] <yasnak> oh but its fun
[13:46:06] <ctjctj_> DaViruz, depends on the hinges. Old rusty things, yuck. Newer ones it seems to last about 6-12 months. And I can have the kids de squeek stuff.
[13:47:35] <gregcnc> autoignition temp of the solvent in WD40 is over 220°C which is still low
[13:49:02] <djdelorie> steel turns straw above that temp, yes?
[13:49:40] <djdelorie> oh - just below
[13:53:46] <ctjctj_> I'm sure you can get your cutting speeds and feeds up to the point where WD-40 might flash. But it would take some effort. If you are cutting at those speeds and feeds you should be using flood cooling.
[13:55:10] <archivist> I have had enough smoke from turning that wide open door needed, never managed flame yet
[13:55:18] <Cromaglious_> WD-40 means Water Displacement formula #40 it was for drying circuits in either Nike missile or Atlas Missile projects
[13:56:09] * ctjctj_ grins "I believe, archivist, that when you are generating that much wd-40 smoke you are pushing the cut.
[13:56:50] <MacGalempsy> right now my garage is up in smoke
[13:56:59] <archivist> ctjctj, usually using the nearest oil can
[13:57:19] <Cromaglious_> Squeaky hinges I either use non-lacquering oil (sewing machine oil) or wax
[13:57:20] <archivist> ep90/whatever
[13:58:26] <ctjctj_> archivist, I started that way. Now I have a sulfur based dark cutting oil by mobile which I use for steels. WD-40 for Al. Trim soluble oil for steel or AL
[13:59:15] <ctjctj_> Tap Magic AL for tapping Al (love the smell of it).
[13:59:44] <djdelorie> I haave a special heavy cutting/tapping oil for stainless, but "whatever" for everything else
[13:59:59] <ctjctj_> I started using the Trim on the bandsaw when cutting a chunk of 2"x5"x24" 6061. That made things so much nicer.
[14:24:26] <miss0r> So I modified the spindle mount on the x-carve, and milled a clamp for a metabo 25k rpm hand grinder, with a 6mm collect in it. Looks nice. Then I realize I can't reach the bottom....
[14:24:28] <miss0r> *sigh*
[14:25:30] <miss0r> https://drive.google.com/open?id=0B51cA8Udo5i7YXpXWHIzZ2ZGQkE
[14:30:21] <Simonious> pink_vampire: thanks, see, not fat. ;)
[14:30:53] <pink_vampire> you are not fat at all.
[14:31:28] <miss0r> whos not fat? :)
[14:31:57] * Simonious <-
[14:32:14] <MacGalempsy> is there a way to skip to a particular line number in the cnc program?
[14:32:27] <MacGalempsy> other than manually edititing the gcode?
[14:32:35] <miss0r> Simonious: Thats good, I guess :)
[14:34:03] <jdh> there is a run-from-here in axis
[14:34:51] <jdh> you could stop, click line, etc but not likely to work
[14:40:16] <ctjctj_> MacGalempsy, not really. You could add an M1 to the Gcode just in front of the place, then use a "run-from-here" there after
[14:48:40] <MacGalempsy> ctjctj_: thanks. I just edited the file, but will keep that in mind
[14:50:36] <ctjctj_> MacGalempsy, I blame cradek for that knowledge. In my tool change gcode I added a M1 so that I had a known moment to turn the spindle back on after a manual tool change.
[15:11:04] <Deejay> re
[15:33:55] <MacGalempsy> geez this is unfortunate...
[15:35:25] <Tom_itx> cut your fingers off?
[15:36:06] <MacGalempsy> not that unfortunate
[15:36:35] <MacGalempsy> there is one area of the cut where the machine is not fully retracting after a cut
[15:37:13] <MacGalempsy> i paused it and tried to tweak the numbers , but fortunately it wont blow the part
[15:37:23] <LeelooMinai> Hmm, apparently it's almost impossible to find edge finder for 1/4 collet (ER11)...
[15:39:10] <Kevin`> LeelooMinai: 1/4 is the max size collet available for er11?
[15:39:25] <LeelooMinai> Well, 7mm, so yes
[15:39:32] <Crom> LeelooMinai and kevin yup, yup
[15:40:08] <LeelooMinai> I am kind of annoyed at this - same with face mills:/
[15:40:21] <Tom_itx> http://littlemachineshop.com/products/product_view.php?ProductID=2543
[15:40:26] <Tom_itx> there you go
[15:41:00] <LeelooMinai> Right, I am in Canada though - ordering anything from USA is a pita - way high postage
[15:41:02] <Kevin`> how do you know what the spot size is at a particular distance?
[15:41:16] <Tom_itx> that was my next question...
[15:41:16] <XXCoder> I wonder how repeatable that is
[15:41:41] <LeelooMinai> I wonder what happens if the laser beam bounces from metal into your retina:p
[15:41:51] <Tom_itx> Includes polarizing attachment to adjust dot size
[15:41:52] <Tom_itx> fwiw
[15:42:14] <Kevin`> LeelooMinai: nothing much, it's an indicator laser, and not even one of the insane ones for lighting up clouds
[15:42:31] <Crom> http://littlemachineshop.com/products/product_view.php?ProductID=1961&category=1261091193
[15:42:32] <LeelooMinai> Right,m it has some danger mark though
[15:42:58] <Tom_itx> http://www.cartertools.com/fm.html
[15:43:02] <Tom_itx> a more sane solution
[15:43:05] <Crom> probably too long
[15:43:08] <Kevin`> I can't see the picture close enough to read what class the laser is
[15:43:13] <Kevin`> would be very suprised if not 1
[15:43:45] <Tom_itx> 1/4" shank standard edge finder. $13.50
[15:44:05] <Deejay> with 20krpm :D
[15:44:07] <Crom> noisey one 14.50 at LMS
[15:44:18] <Crom> same price both places
[15:44:29] <LeelooMinai> I watched a video yesterday with some old giy showing different indication methods and he insisted that the indicators that do not work as the two cylinder ones with spring inside are not as good because they do not take collet runout into the acout (whereas the cylinder ones align with the true axis of the spindle automatically)
[15:44:34] <Kevin`> yeah, what's the max speed of an edge finder? will it explode or 400rpm?
[15:44:58] <Kevin`> my chinese spindle only goes so much slow :/
[15:45:08] <Tom_itx> heh
[15:45:14] <Kevin`> *at
[15:45:16] <Tom_itx> typically you use them at a low rpm
[15:45:36] <Deejay> i ran one at ~10krpm, no good idea :/
[15:45:48] <Crom> so want an ER20 spindle..
[15:45:49] <Sync> LeelooMinai: sure, but your spindle does not run out much
[15:45:56] <LeelooMinai> I imagine at 20k rpm the little cilinder would fly off and break the spring:)
[15:45:57] <Tom_itx> use a .2500000 dowel pin and a .001 feeler gage
[15:46:43] <Tom_itx> probably more accurate than a wiggler anyway
[15:46:47] <Kevin`> LeelooMinai: cylinder ones?
[15:47:09] <XXCoder> I usually use 1000 rpm for edgefinder
[15:47:19] <XXCoder> thats what starret suggests for theirs
[15:47:21] <LeelooMinai> Yes, I mean the chipest ones where you observe two cylinders align - they are connected with a spring inside basically.
[15:47:35] <Kevin`> LeelooMinai: what's the other type?
[15:47:48] <ctjctj_> LeelooMinai, "Search for CNC probe ebay" $167
[15:47:49] <Crom> if you clap down a metallic part so it's insulated from the bed. I just use drill rod and a buzzer + light
[15:48:30] <LeelooMinai> Well, there are "digital" ones with a led, for metal objects. And other techniques like using indicator. The guy even had some optical contraption where you looked at the side and you saw the axis from the top - it was pretty neat.
[15:48:46] <MacGalempsy> https://www.flickr.com/photos/58181938@N03/29368598295/in/dateposted-public/
[15:48:46] <LeelooMinai> And expensive ones like Heimer thing.
[15:48:48] <Sync> yeah a microscope
[15:48:51] <Sync> they are pretty neat
[15:48:58] <Sync> a 3d probe is not expensive
[15:49:06] <MacGalempsy> That is a picture of the kiss. any idea how to resolve this issue?
[15:49:14] <LeelooMinai> Heimer is $400 or so I think.
[15:49:30] <MacGalempsy> is it a tool height setting in the cad? I increased the retract height to .5" above the workpiece and it still does it
[15:49:31] <Crom> mac the divot top right third?
[15:49:39] <MacGalempsy> yea
[15:50:10] <ctjctj_> Kevin`, I can promise you they do explode at 27,500
[15:50:38] <Sync> about that LeelooMinai, there are also the tschorn ones for 300
[15:50:41] <Sync> which is not bad tbh
[15:50:45] <Kevin`> if they work at 1000rpm it should be fine, spindle will do that easily although the torque is low
[15:50:46] <LeelooMinai> I only can tell you not to switch the spindle on at 8k rpm with an indicator inside.
[15:51:09] <Kevin`> ouch
[15:51:13] <LeelooMinai> That's what I learned so far:)
[15:51:24] <Crom> add a G0 Zx; G0 Xx Yx; into the retract in the pre processor
[15:52:05] <ctjctj_> Crom, maybe do that in G53 and not in current coordinate system?
[15:52:47] <Crom> mac.. G60 or G61?
[15:52:57] <Crom> that might be your culprit
[15:52:58] <ctjctj_> LeelooMinai, I needed to find the center of a hole so decided to try it. Was smart and was standing back of a shield as the spindle spun up. The hole in the shield and the rip in my shirt were not fun.
[15:53:13] <Crom> follow exact, follow near
[15:53:26] <Crom> keep forgetting which one it is
[15:53:59] <Crom> or can you set a rule to retract all the way before move?
[15:54:00] <LeelooMinai> ctjctj_: That's why I am making enclosure for my CNC with 1/4 polycarbonate panes:)
[15:55:12] <Crom> I like 1/8" glass, 1/4" polycarb,1/8" glass, 1/4 poly carb, 1/8" glass
[15:55:31] <LeelooMinai> Right, in case someone shoots it with RPG
[15:55:40] <Crom> all stuck together with silicon
[15:56:40] <Crom> the glass eats a ton of energy.. rigid,soft,rigid,soft,rigid best way to make armor
[15:57:31] <Crom> yeah you'll have to replace it eat time something flys into it.. maybe I can live with scratched up poly carb
[15:58:08] <LeelooMinai> Well, better that than having it embedded in you imo
[15:58:14] <Crom> ER16 would work too.. that'll hold 3/8"
[15:59:11] <LeelooMinai> Right, I wish I had er20 spindle, but I could not really use it in my room as I am limited by the 16A or so of the sockets in my room.
[15:59:31] <Crom> ER16 will do 1/2" ER20 does 3/4"
[15:59:56] <Crom> 16a at how many volts?
[16:00:01] <LeelooMinai> Right 1/2 is all one needs
[16:00:04] <LeelooMinai> 110
[16:00:15] <Crom> just the one circuit..
[16:00:22] <MacGalempsy> er20 is only up to 1/2"
[16:00:33] <Crom> 20mm / 25.4 is .78
[16:00:43] <LeelooMinai> I think 20 is outside dia
[16:01:04] <Crom> hmm
[16:01:22] <MacGalempsy> Crom: any idea how to do that with Fusion 360?
[16:02:50] <MacGalempsy> maybe remove rapid retract?
[16:03:03] <Crom> er16 is good for 13/32 with special to 7/16" so Er20 it is for 1/2" special to 9/16"
[16:03:14] <Crom> mac I'd have to go look...
[16:05:13] <Crom> G61/G64 are the codes G61 is exact, G64 cancels G61
[16:05:37] <Crom> bbiab fusion machine is in other room
[16:10:39] <MacGalempsy> I think that setting is good. There is a forum here about the EMC2 postprocessor for fusion, maybe it will lead to a fix
[16:18:51] <Crom> search youtube for fusion 360 post processor walkthrough
[16:19:02] <MacGalempsy> hmm, Iam going to fudge the tool height an extra .75"
[16:20:22] <Crom> once you find the retract function in the F360 PP scrpit you can add a G61 before and a G64 after the retract move
[16:20:45] <MacGalempsy> retract to safe plane?
[16:20:57] <Crom> yep
[16:21:25] <Crom> make it go straight up them move onces it's at safe plane
[16:21:35] <MacGalempsy> ok
[16:22:42] <MacGalempsy> I noticed a section in the post processor that says //Note: add retract here
[16:23:36] <Crom> I've seen it bite others peoples butts.. NYCCNC for one.. like your part... Really high feature and the next spot to cut is thru the feature.. the path pridicter doesn't accound for things in the way
[16:24:59] <Crom> switch on G61, it goes straight without rounding thru a path predictor
[16:26:02] <Crom> turns you sine wave path into a square wave
[16:30:33] <skunkworks> MacGalempsy, you need to set the G64 Px.xxx tollerence.
[16:31:01] <MacGalempsy> is that in the post processor?
[16:31:23] <skunkworks> that is a gcode
[16:32:05] <skunkworks> if you don't the G64 tolerance - linuxcnc will go as fast as it can rounding corners as much as it can
[16:32:40] <MacGalempsy> the postprocessor does not produce a g64 code
[16:32:57] <djdelorie> so thats why all my runs resulted in a big circle...
[16:33:03] <skunkworks> so if you say G64P.005 - that says go as fast as you can but don't diviate from the programmed path more than .005" or whatever units you are running
[16:35:59] <MacGalempsy> here is a forum post in LCNC with the exact same issue
[16:36:27] <MacGalempsy> he states raising the retraction height, so that is what I will do
[16:39:29] <Deejay> gn8
[16:43:54] <Crom> mac G60 might also work for retracts... G60 Z[safe height] does not go thru predictive unit
[17:01:04] <MacGalempsy> guys, I appreciate the info on the G60 and g64. Unfortunately, my abilities to program are limited.
[17:08:06] <skunkworks> you would just put it at the begining of your gcode program
[17:08:07] <skunkworks> one time
[17:37:49] <MacGalempsy> oh. then that is easy
[17:38:16] <MacGalempsy> well, the wifey is home for the evening, so no more machinging today :(
[17:38:54] <MacGalempsy> That would be ok, if Battlefield 1 servers were not down, too....
[17:46:33] <MacGalempsy> https://www.thebranfordgroup.com/dnn3/Employees/OnlineAuctionAdmin/RandcoToolMold/tabid/1588/AuctionID/1334/Default.aspx?page=1
[17:46:44] <MacGalempsy> anyone see anything they like?
[18:02:49] <Tom_itx> I don't see G60 in the docs
[18:03:05] <gregcnc> I think he means G61
[18:03:24] <Tom_itx> makes more sense
[18:06:51] <Crom> or G09
[18:07:08] <gregcnc> what control?
[18:07:10] <Crom> non modal move, don't go thru predictor
[18:08:37] <Crom> woo block sets.. lot 9 and 10.. I can do $50
[18:08:54] <MacGalempsy> Crom: where are you?
[18:09:26] <Crom> California, So Cal, Riverside county on the I-15 in Temecula
[18:09:52] <Crom> you there in OK?
[18:10:03] <MacGalempsy> There are 2 auctions going on that are in the same small town (Poteau, OK) if anyone sees anything they want to arrange shipping on, let me know
[18:10:42] <MacGalempsy> Im going to check out the cabinets of electrical parts and tooling
[18:10:57] <Crom> hmm lot 28 is R-8
[18:11:07] <Crom> I can't afford that
[18:11:43] <MacGalempsy> there are 2 shops closing. Randco tool and mold, and kenco plasics (sounds like a brother thing)
[18:13:16] <MacGalempsy> I like the Van Dorn 85 ton injectoin machine
[18:13:21] <Crom> wooo lot 67 randco
[18:14:28] <MacGalempsy> tell you what, you win that one, and I will take one and ship the other for free
[18:15:18] <Crom> oh who was it needed 3J collets Keith Rucker?
[18:15:54] <Crom> definately... you have a paypal account?
[18:16:52] <MacGalempsy> sure. so I am going down to preview the lots on the 7th and bidding closes at 10am on the 8th
[18:16:56] <Crom> damn payday is tomorrow.. don't know how much I'm getting... hopefully it's the $533
[18:16:59] <MacGalempsy> online bidding only
[18:18:00] <MacGalempsy> how about lot 101?
[18:18:18] <MacGalempsy> any why not 102, too?
[18:18:53] <MacGalempsy> holy crap 103 is just the size for my garage! lol
[18:20:00] <gregcnc> let me know if you think you can put 203 into a flat rate box
[18:20:11] <Crom> sheeshz... 101 or 102, I'd have to drive out there and pick it up
[18:20:34] <MacGalempsy> I think that pushes the max density
[18:21:37] <Crom> I don't think so... to many cubes... even ground up
[18:21:47] <MacGalempsy> 205 would be good on the wilton drillpress
[18:24:06] <Crom> any of the 180's
[18:24:27] <Crom> be fun trying to stick that into a flat rate box
[18:26:24] <Crom> 241 would be nice...
[18:27:13] <MacGalempsy> those are too big for my mill
[18:28:40] <Crom> 267 and 268... might be able to witle those down to fit a priority mail box
[18:30:29] <Crom> 263, perfect size for a Sieg X2
[18:30:59] <Crom> to sit on... not to be used on
[18:32:00] <Crom> oh to be able to get 231...
[18:32:24] <Crom> that's a drive out and pick up as well...
[18:33:47] <Crom> lot 226 are SO handy.. I have a 5amp one...grab and pull out to the car... great for the battery charger or work light
[18:35:19] <Crom> damn... dont tell the mounts on the chucks
[18:36:15] <Crom> woo 218 thru 220 would be nice if you had a mill
[18:37:18] <Crom> oh wow 205 is XY and _Z_
[18:48:51] <Tom_itx> what's the app of choice for burning dvd's in linux?
[18:49:56] <Flipp_> do you have to be there in person for the auction? or do they ship?
[18:50:35] <Valen> dvds? they are still a thing?
[18:50:53] <Tom_itx> for this project they are
[18:50:54] <Valen> it's been so long I have forgotten what I used to use lol
[18:51:02] <Valen> it was command line though
[18:51:41] <Tom_itx> i gotta pull some crap off someone's hdd so i can format it
[19:06:26] <Tom_itx> meh, thumbdrive may be easier...
[19:08:43] <malcom2073> Thumbdrives are always easier
[19:09:08] <Tom_itx> i was just gonna send the disk with them since it's not going back on the drive...
[19:20:56] <Simonious> planning to remove the USB plug on http://www.collection.archivist.info/archive/mirror/cnc/bob/$_57.JPG it's a little in my way, why is that thing even there?
[19:21:30] <malcom2073> To charge your iphone obviously.
[19:22:01] <tiwake> CNC machine iPhone charing station
[19:22:04] <malcom2073> heh
[19:22:15] <malcom2073> Seriously though, I've seen b connectors for the 5v power
[19:22:18] <malcom2073> but that's odd to see an A
[19:22:24] <malcom2073> Meaning to get power *to* the bob
[19:22:49] <malcom2073> Maybe you're supposed to use an A to A cable to provide 5v power for the PC side of the optoisolators?
[19:23:14] <Simonious> Hm
[19:23:23] <Simonious> thre is a 12V input and it looks like a v step down
[19:23:27] <Simonious> *there
[19:23:40] <malcom2073> that would be kinda bad design to have an optoisolated board that isn't actually isolated
[19:24:01] <malcom2073> Wouldn't be shocked though (no pun intended)
[19:24:15] <Meduza> Simonious: it uses that USB connector and a A-A cable for powering the board
[19:25:15] <Meduza> It does not work without it... (i also removed that connector since I thought it would not be needed...
[19:26:16] <Meduza> It is used for the optocouplers
[19:26:27] <Meduza> As malcom2073 suspected
[19:26:40] <Valen> Tom_itx: can nautilus do it by itself?
[19:26:48] <Simonious> Meduza: there is a 12V input and a 5V input...
[19:27:16] <Simonious> Meduza: 5V bottom right..
[19:27:22] <Simonious> should take care of me.. testing shortly
[19:28:47] <Tom_itx> Valen, i have no idea. i don't burn dvds on linux
[19:28:56] <Tom_itx> but i'm having to use it for this project
[19:30:54] <Simonious> Meduza: yup, usb connector not needed, can supply 5V at bottom right
[19:31:44] <Meduza> Ok, then feel free to remove the connector :)
[19:32:14] <Simonious> Meduza: the way you say that makes me suspicious that you think I'm missing something..
[19:32:22] <Simonious> still exact same board response for power one place or the other..
[19:33:58] <Meduza> No, I suspect there is different revisions of that board, since the one I tested on did not work to power trough that screw connector, but that did not work at all, so yours is probably different
[19:34:51] <Simonious> my 5V power light and relay light both come on when power is applied to the USB connector or to that 5V connector
[19:34:54] * Simonious shrugs
[19:35:00] <Simonious> I don't have a manual
[19:49:08] <Simonious> this bob is kinda the wrong gender
[19:53:37] <Simonious> ahh, no it's fine.. just have to use the cable that isn't male on both ends
[20:05:06] <Simonious> okay, so my limit switches are of the normal on variety and I'm going to put XYZ all on one pin
[20:05:09] * Simonious thinks
[20:07:34] <Simonious> archivist: here is one to add to your dir http://www.collection.archivist.info/archive/mirror/cnc/bob/$_57.JPG if you want the bottom labels
[20:07:41] <Simonious> https://goo.gl/photos/eNwRSuF9NJmMKLzR6
[20:08:18] <malcom2073> Heh, tapmatic was on amazon with a pricing mistake, $190 instead of $1900
[20:08:23] <malcom2073> I bought one... we'll see if it went through
[20:13:32] <gregcnc> which model costs $1900?
[20:14:18] <malcom2073> Well costs $1900 on ebay, they're like $600 on ebay. It's the RX 70
[20:14:25] <malcom2073> $1900 on amazon*
[20:14:38] <gregcnc> yeah OK
[20:14:58] <gregcnc> I have two 30's I need to finish cleaning to sell
[20:16:14] <malcom2073> I have one, forget what kind, goes up to 1/4-20. I need to get it running on the mill at some point. Bought it used a while back
[20:38:42] <Simonious> http://www.collection.archivist.info/archive/mirror/cnc/bob/$_57.JPG so on BOB here, do I need the 12-24V power? what is that for?
[20:39:21] <pfred1> Simonious power I imagine
[20:39:34] <pfred1> by the power of greyskull!
[20:39:41] <Simonious> pfred1: that seems to be what the 5v input is for
[20:40:01] <pfred1> well it is for if you don't have regulated 5V
[20:40:12] <pfred1> there's probably an onboard regulator
[20:40:16] <malcom2073> Simonious: The 5v probably powers the 5v side of the optos
[20:40:23] <LeelooMinai> Wouldn't that be what is named "field power" usually (the 12-24V)?
[20:40:24] <malcom2073> and the 12-24 probably powers the 12-24v side of them
[20:40:41] <Simonious> huh..
[20:40:50] <pfred1> meh when I do opto circuits they're 5V on both sides
[20:40:57] <malcom2073> Could be what that little 5v regulator is doing
[20:41:01] <malcom2073> turning 12-24 into 5v
[20:41:17] <pfred1> you really need to control the current all around
[20:42:05] <Simonious> pfred1: yeah? my 24V side is limited, I think the 5V wart is self protected too..
[20:42:08] <Simonious> is that what you mean?
[20:42:26] <pfred1> I mean you'll blow otu the sender, or the receiver if you don't
[20:42:37] <Simonious> if I don't.. what?
[20:42:43] <pfred1> they're a diode and a phototransistor
[20:43:21] <pfred1> so the diode there's a current limiting resistor and the transistor there's a pull up resistor
[20:43:42] <pfred1> but the values of those depend on the input voltage
[20:43:57] * Simonious is a little puzzled.
[20:44:02] <Simonious> instructions would be nice, oh well..
[20:44:23] <Simonious> so I've got 24V on the one side, 5V on the other.. that seems to be what is called for here..
[20:45:16] <pfred1> well if you have the right resistor 24V is OK
[20:45:37] <pfred1> that's probably your diode side
[20:45:48] <pfred1> there's a little LED inside the optocoupler
[20:45:53] <LeelooMinai> imo the 5V side should come from the PC and be in the same "domain" as all the parallel port signals. That should bbe isolated from the 12-24V part that is the "field" power and is what is being controlled.
[20:46:15] <pfred1> but like all LEDs too much current and it goes poof
[20:46:34] <LeelooMinai> Controled or read as inputs that is, but still isolated.
[20:47:12] <pfred1> drive strength with optos does vary depending on the device
[20:48:00] <pfred1> are there device numbers on the optocoupler packages?
[20:48:11] <Simonious> http://www.collection.archivist.info/archive/mirror/cnc/bob/$_57.JPG
[20:48:47] <pfred1> I can't read those worth a damn
[20:48:55] <pfred1> C234?
[20:49:07] <LeelooMinai> 334 imo
[20:52:24] <pfred1> yeah i ain't finding nothing
[20:53:18] <LeelooMinai> Well, on those Chinese boards, I would not expect brand names, especially for such primitive parts as optos - they are probably some Chinese cheap versions of usual ones
[20:53:33] <pfred1> still something to go off of
[20:54:22] <pfred1> looking at the whole image I'd say the 5V is just so the PC is at the same potential as the BOB
[20:54:30] <pfred1> so the logic level is right
[20:54:48] <pfred1> the board runs off that 12-24 feed though
[20:55:12] <Simonious> I'm seeing that 12-24 feed is optional, and only needed if you are using the endstop inputs
[20:55:26] <Simonious> I'm getting lights for 5V and lights for 12-24V
[20:55:34] <pfred1> you really don't want to distribute 5V to a board
[20:55:54] <pfred1> regulation sucks at the end of a wire
[20:55:56] <Simonious> what do I really want to do?
[20:56:06] <pfred1> you want to regulate on board
[20:56:16] <LeelooMinai> As I wrote, it's probably "field power" - the voltage you would apply to the switches, etc.
[20:56:19] <Simonious> well.. that'd be nice, but we aren't doig that here I guess
[20:56:32] <pfred1> nah there's a regulator on that board
[20:56:46] <pfred1> right under the relay
[20:56:52] <Simonious> well the 5V stuff doesn't light up if I supply 12V only, but maybe I don't need it to.
[20:56:55] * Simonious shrugs
[20:57:29] <LeelooMinai> Well, the regulator is there, but maybe it just exposes 5V on those PC 5V, GND outputs
[20:57:31] <pfred1> unless that is a transistor to switch the relay
[20:57:57] <pfred1> kind of hard to tell in just an image
[20:58:02] <Simonious> hey look, a little documentation http://www.omc-stepperonline.com/5-axis-cnc-breakout-board-interface-for-stepper-motor-driver-stv2-p-197.html
[20:58:04] <LeelooMinai> So I would say that regulator supplies 5V but it's on the isolated side, not the same side as the USB input
[20:58:28] <Simonious> looks like you are right and the 5V is optional
[20:58:35] <pfred1> yeah isolation is pretty pointless if you use same power both sides
[20:59:06] <Cromaglious_> wooo
[20:59:16] <Simonious> archivist: http://www.omc-stepperonline.com/download/pdf/5_Axis_CNC_Breakout_Board_Interface_Users_Manual.pdf
[20:59:18] <pfred1> Simonious I've just built stuff so I know what works, and what doesn't
[20:59:45] <Simonious> pfred1: so skipping the 5V is the way to go here and just give it 12-24v?
[21:00:02] <Cromaglious_> PWM not working still... can't pload to the arduino nano... grrrr
[21:00:06] <pfred1> well the 5V is a level reference
[21:00:17] <pfred1> so the logic of the board is the right level for the PC
[21:00:25] <Simonious> pfred1: which.. it'll get off the parallel port...?
[21:01:14] <pfred1> is there 5V on the p-port?
[21:01:33] <pfred1> been a while since I messed with one
[21:01:40] <LeelooMinai> I don't think it has power supply pins - that's why there is USB port...
[21:01:47] <Simonious> pfred1: depends on the port - some are at 3.3V
[21:01:55] <pfred1> that is true
[21:01:58] <Simonious> parallel ports aren't always real compliant
[21:02:07] <pfred1> that's why you use a BOB
[21:02:12] <Simonious> aye
[21:02:33] <Simonious> as long as the PC and the BOB are sharing a ground we should be fine for level I'd think.
[21:02:40] <pfred1> I looked for days on the net for specs for a modern emulated p-port
[21:02:51] <pfred1> none such animal exists
[21:03:16] <pfred1> the original AT that had a real 16650 had a spec
[21:03:34] <pfred1> but since the port got integrated into chipsets it is a mystery
[21:04:59] <pfred1> so when I made my BOB I made rue it only loaded the port down by microamps
[21:05:10] <pfred1> made sure even
[21:05:25] <pfred1> I figured the port had to be able to handle that
[21:06:01] <pfred1> so far so good over here too
[21:07:07] <pfred1> because a bad spec p-port seemed somewhere in the neighborhood of 3ma to me
[21:07:39] <pfred1> based on what i could find about it all
[21:10:18] * pfred1 is so excited over here http://i.imgur.com/26hQac7.jpg
[21:10:34] <pfred1> I got the latest inkscape running on my crusty Wheezy install
[21:10:49] <pfred1> it really was easy
[21:10:58] <Simonious> ugh, sounds slow as heck even on a pi3
[21:11:07] <pfred1> what is?
[21:11:12] <Simonious> inkscape?
[21:11:21] <pfred1> oh its not bad
[21:11:30] <pfred1> it did take a while to build it is a huge app
[21:12:00] <pfred1> the binary is ~151MB?
[21:12:10] <pfred1> somewhere around there
[21:12:34] <LeelooMinai> I remember when I had to run Inscape - downloaded, installed, 3 minutes done:p
[21:12:36] <pfred1> the jury is still out with gcodetools though
[21:12:49] <tiwake> <3 inkscape
[21:12:52] <pfred1> LeelooMinai I had version 0.48
[21:12:58] <tiwake> its such a fantastic open source program
[21:13:05] <pfred1> but gcodetools doesn't work with it
[21:13:06] <LeelooMinai> Right, but why are you building stuff...
[21:13:22] <pfred1> because that is the latest version available for my distro
[21:13:57] <pfred1> I'm not going to install a new distro just to upgrade one app
[21:14:15] <pfred1> let's be real
[21:14:30] <pfred1> it took me years to get this setup the way i like it
[21:14:36] <LeelooMinai> Could be faster:)
[21:14:41] <pfred1> no way
[21:15:12] <pfred1> upgrading once every 10 years is enough for me
[21:20:41] <Cromaglious_> I tend to use turnkey, then again I'm doing laser for the most part... Now I got the 3040 running again... I need to find something usable
[21:23:04] <Cromaglious_> firing up wine to get some solidworks files
[21:35:05] <Cromaglious_> hohum... wanders off while freecad is downloading
[21:35:06] <dioz> is this a good welder
[21:35:07] <dioz> https://www.amazon.com/dp/B00REX6USW/ref=dra_a_rv_hp_hn_xx_P1200_1000?tag=dradisplay-20&ascsubtag=0f1042a998d77ed66e19a3eb35150f5a_S ?
[21:35:10] <dioz> https://www.amazon.com/dp/B00REX6USW/ref=dra_a_rv_hp_hn_xx_P1200_1000?tag=dradisplay-20&ascsubtag=0f1042a998d77ed66e19a3eb35150f5a_S ?
[21:35:17] <dioz> oops sorry bout the double paste
[21:37:07] <Cromaglious_> search youtube for chucke2009 one of his recent video's was review something similar... I think similar price
[21:37:24] <dioz> yah i watch chucke2009
[21:38:22] <Cromaglious_> I'd buy anything he uses... except his first lathe...
[21:38:58] <Cromaglious_> really wanting to get a hypertherm plasma with it's own built in air compressor
[21:39:45] <Cromaglious_> his tractor is really nice!
[21:39:58] <Cromaglious_> even if it was built in India
[21:40:20] <Cromaglious_> it's a basic clone of a 1960's us tractor
[21:41:33] <Cromaglious_> switching computers
[21:59:30] <Crom> ack... wrong channel... whats the amazon link for the welder again? https://www.youtube.com/watch?v=8sXizqc5W_Y
[22:03:21] <pfred1> that chucky kid is such an idiot
[22:04:16] <pfred1> but kids are
[22:04:28] <Crom> funny too...
[22:04:39] <Crom> knows welding though
[22:04:43] <pfred1> well at least he admits he doesn't knwo what he's doing
[22:05:22] <Crom> I never know what I'm doing... But I've probably done something close to it
[22:05:23] <pfred1> I guess
[22:06:03] <pfred1> to me welding is the fabricaiton method of last resort
[22:06:19] <Crom> having a basic understanding of Physics and geometry has saved my arse plenty of times..
[22:06:55] <Crom> well and organic or otherwise of chemistry
[22:07:38] <pfred1> now jodie from tips and tricks he knows his stuff
[22:08:05] <Crom> welding is usually one of my first... or soldering or glueing,
[22:08:11] <pfred1> his video on distortion is enlightening
[22:08:21] <Crom> smarter every day is good too
[22:09:13] <pfred1> I like good old hardware
[22:09:31] <Crom> I like hardware that works...
[22:09:33] <pfred1> tapped holes and bolts
[22:09:47] <pfred1> looks so much neater so much easier to live with
[22:10:28] <pfred1> so muh more precise
[22:10:55] <Crom> I do alot of theatrical stuff... glue, welding, lots of staples and screws are your friends.
[22:11:19] <Crom> don't get to use alot of bolts
[22:11:39] <Crom> except carriage bolts bolting the stage together
[22:12:13] <pfred1> like here's a lathe i made http://i.imgur.com/7KTgP1C.jpg
[22:12:17] <pfred1> very little welding
[22:13:00] <pfred1> you can see one of my welders in the background though :)
[22:14:50] <Crom> need oil cups on the bearings, heh..
[22:15:04] <pfred1> I need real bearings
[22:15:14] <pfred1> it is on the 2 do list
[22:16:38] <pfred1> but being as those caps are just bolted on I'll be able to change them out
[22:16:50] <pfred1> because it's not welded!
[22:16:54] <Crom> 1" end caps, drill and tape a 1/8 npt in the end, then you can put a what ever nipple on the cap and fill with oil, or you could rig a metering thingy on the 1/8"
[22:17:11] <Crom> s/tape/tap/
[22:17:53] <pfred1> when stuff is all welded up making modifications is problematic
[22:17:59] <Crom> I have a 1945 war production Sheldon over head leather belt drive
[22:18:32] <Crom> plain babbit bearing
[22:18:53] <pfred1> I have a babbet arbor grinder
[22:19:05] <Simonious> hmm pfred1 so you talked about using the USB as a voltage reference, right?
[22:20:12] <pfred1> Simonious not precisely but you could
[22:20:27] <Simonious> I put a 5V wall wart on those pins.. http://www.collection.archivist.info/archive/mirror/cnc/bob/$_57.JPG
[22:20:30] <pfred1> Crom http://i.imgur.com/tMwheuz.jpg
[22:20:32] <Simonious> (bottom right)
[22:20:48] <Simonious> hooked up just XYZ, step, dir and no movement at all
[22:21:15] <Simonious> having just moved from a different breakout board, so.. I'm thinking that reference voltage needs to be from the PC.. you know as labeled on the BOB
[22:21:26] <Crom> pfred1, nice, even nicer is the basket of hammers
[22:21:27] <pfred1> well I think the 5V and PC ground are so you are referenced to your PC's voltage levels
[22:21:36] <Simonious> Right...
[22:21:38] <pfred1> Crom heh my own design
[22:21:51] <Simonious> was hoping to avoid running a long ass USB cable in addition to a long ass parallel cable
[22:22:08] <pfred1> yeah the parallel cable has the ground
[22:22:30] <Crom> Simonious, I got a 12v-24v usb power adapter and using that..
[22:23:11] <Crom> using a bunch of diodes to drop the 28v to 23v ish
[22:23:14] <Simonious> Crom: I've got a 5V wall wart on the PC 5V pins and a 24V 7A supply on the 12-24 input
[22:23:39] <pfred1> Crom a pic of the hammer basket http://i.imgur.com/nf0pKFr.jpg
[22:23:42] <Simonious> and zero movement, my best theory is those pins labeled PCV really need PC reference voltage
[22:23:49] <Crom> 5v wall wart, or usb wall wart?
[22:23:58] <Simonious> 5V wall wart
[22:24:10] <pfred1> wall warts usually are not very tightly regulated
[22:24:16] <Simonious> this one isn't bad
[22:24:24] <Simonious> I tested a couple before I picked one
[22:24:31] <pfred1> I don't think that is what those lines are for anyways but maybe?
[22:24:32] <Crom> oh AND a Beck bottle opener!
[22:24:33] <Simonious> it's locked in at 5V with no load
[22:24:36] <Crom> nice
[22:24:59] <Simonious> well when I hook the 5V in there it lights up the 5V power LED exactly like when I hook up the USB port
[22:25:00] <pfred1> Crom I got that at a christmas eve stripper club party
[22:25:05] <Simonious> so I hoped I was gold
[22:25:06] <Crom> hehe
[22:25:10] <pfred1> 100 dancers!
[22:25:20] <Simonious> I guess I should have taken the onboard USB as a hint
[22:25:26] <Simonious> I desoldered it..
[22:25:26] <pfred1> so it is a treasured possession
[22:25:28] <Simonious> it was in my way
[22:25:53] <Crom> really how many could really dance? My Wife's degree is in dance... we're a little picky about dancers
[22:26:06] <pfred1> well they didn't al ldance at once
[22:26:16] <pfred1> it was an all night kind of a thing
[22:26:26] <Simonious> Crom: I took some lessons from Frankie Manning, also got to perform for him before I had met him.
[22:28:08] <pfred1> Simonious I think you'e going to have to just ring that board out to suss otu how it works
[22:29:04] <Crom> Wife studied with Claude thompson ('68 elvis special), Michael Roonie, and others she studied at Glendale College (a community college with a world class dance program)
[22:29:06] <pfred1> like find out where the power for the logic chips comes from on it
[22:30:29] <pfred1> ghost board http://i.imgur.com/P7lPCXQ.jpg
[22:30:41] <Crom> wooo nice! one of the old time tap dancers
[22:30:53] <Simonious> pfred1: gonna make the LONG USB run and see if that helps me out
[22:31:13] <pfred1> Simonious with electronics you keep guessing and yo uend up blowing stuff up
[22:31:40] <pfred1> lots of times its one strike and you're out
[22:31:45] <Crom> ahhh Lindy hop
[22:33:22] <pfred1> Simonious really without an oscilloscope you're flying blind with this stuff
[22:33:41] <Simonious> pfred1: I've got the oscope..
[22:33:43] * Simonious ponders
[22:33:51] <pfred1> well hook it up
[22:34:06] <Simonious> that's fair
[22:34:17] <pfred1> see if you're gettign step pulses
[22:35:25] <Crom> https://www.youtube.com/watch?v=m34eD21QzUw
[22:40:19] <Simonious> pfred1: ziltch, the old bob works, this one doesn't, the old bob has 5V reference off the USB though
[22:41:06] <pfred1> Simonious check the VCC of the logic IC
[22:41:12] <pfred1> make sure it has power
[22:41:49] <pfred1> probably going to be the most clockwise pin the highest number
[22:42:02] <Crom> My bob has to have 5v and 12-24v 5v is the PC side and the 12v-24v is the cnc side
[22:42:03] <LeelooMinai> I would start from just using DMM in ohm mode first, testing what is connected to what, then power it and use DMM in voltage mode to test voltages around.
[22:42:22] <pfred1> LeelooMinai yes
[22:42:44] <pfred1> electronics need power
[22:42:53] <Simonious> hmm, I take it back.. had a hook up error
[22:42:55] <Simonious> put the scope on
[22:43:04] <Simonious> got step and dir as 5V as expected after the BOB
[22:43:09] <Simonious> but nothing from the stepper
[22:43:16] <Simonious> odd
[22:43:20] <Simonious> this worked on the other bob
[22:43:40] <pfred1> maybe this BOB doesn't have the current to drive your drives?
[22:43:46] <pfred1> yoru drives isolated?
[22:44:39] <pfred1> optos need quite a bit of current to fire
[22:45:11] <Crom> oh it was Frankie Owens I was thinking of
[22:45:47] <pfred1> I was never a dancer myself but i like to watch soem folks dance
[22:47:37] <Simonious> pfred1: the 5V supply and the 24V supply both have plenty of current to give
[22:47:56] <pfred1> Simonious yeah they're not what drives the logic optput though
[22:48:01] <pfred1> output even
[22:48:32] <pfred1> there's a buffer chip on that board that does that
[22:48:47] <pfred1> it should be up to it
[22:48:56] <Simonious> pfred1: My old BOB was a bunch of 2222s that I built.. but it was only 3 axis
[22:49:09] <Simonious> I was going to expand it, but then this thing was cheap, so I didn't want to waste the time..
[22:49:12] <pfred1> yeah a 2222 can supply 150ma
[22:49:27] <pfred1> more than most ICs
[22:49:36] <Simonious> the drives are GECKO320s
[22:49:43] <pfred1> yeah they got optos in them
[22:49:44] <Simonious> I would expect high impedence inputs...
[22:49:54] <Simonious> oh right
[22:50:01] <Simonious> so I'm double isolated..
[22:50:03] * Simonious shrugs
[22:50:07] <pfred1> nah
[22:50:16] <pfred1> the optos are only on the inputs of that BOB
[22:50:32] <pfred1> there's a buffer for the outputs
[22:50:42] <Simonious> ok, that makes good sense
[22:50:49] <pfred1> least that is how it looks
[22:51:13] <Simonious> I'm tempted to hook the old BOB up just for sanity to make the steppers move again..
[22:51:18] <Simonious> hate to kill the time to do that
[22:51:28] <pfred1> when you have the drive hooked to the BOB and you are sending a step pulse train through can you see a signal on the step line?
[22:51:44] <Simonious> yes
[22:52:07] <Simonious> but lets back up and clarify
[22:52:13] <pfred1> is there an enable line on yoru stepepr drives?
[22:52:24] <pfred1> because if that is true they should work
[22:52:29] <Simonious> I've got the parallel port to the BOB to the stepper driver
[22:52:33] <pfred1> if there's a step signal there with the load
[22:52:41] <Simonious> I'm putting the scope on the BOB output
[22:52:45] <Simonious> and seeing step and DIR signal
[22:52:45] <pfred1> right
[22:53:00] <pfred1> its the right level?
[22:53:07] <Simonious> 5V
[22:53:13] <pfred1> that would be it
[22:53:17] <Simonious> same level I was using w/ the old BOB
[22:53:34] <pfred1> then why doesn't your drive run?
[22:53:45] <pfred1> you're sending it the control pulse train
[22:53:53] <Simonious> this is why I want to put the old BOB back just to see them move
[22:54:24] <pfred1> you have your power to your drives right?
[22:54:39] <Simonious> yeah and all the usual noise and jitter that goes with it
[22:54:41] <pfred1> like the high VDC input
[22:54:46] <Simonious> aye
[22:55:29] <pfred1> the only thing i can think of is your drives are disabled holding
[22:55:46] <Simonious> it's not impossible
[22:55:59] <pfred1> geckos go into a low current hold mode
[22:56:27] <pfred1> when they're not actually stepping
[22:56:50] <Simonious> I'm wandering back over to the machine to poke it a bit bbiab
[22:57:03] <pfred1> but once yo u send a step pulse stream to the drive it should go
[23:06:37] <Simonious> I hooked up step, dir and ground to a single axis through the old BOB, the step and DIR LEDs on the BOB light up as usual, but zero motion on the machine, so something else is up.
[23:06:59] <pfred1> I figured as much
[23:07:03] <pfred1> because it should work
[23:07:12] <Simonious> I didn't scope it, but I'm reasonably sure it's there
[23:08:24] <pfred1> I should take a picture of my rube goldberg electronics
[23:08:40] <pfred1> frankly I'm amazed it works
[23:08:55] <pfred1> but it always does
[23:09:50] <pfred1> I need to figure out why that PC gets unexpected real time delays
[23:09:50] <Simonious> https://goo.gl/photos/h5RXcd5oxHhGqAZ26
[23:09:54] <Simonious> this should have worked
[23:11:10] <pfred1> why do you have 2 wires going into P2 and P3?
[23:11:21] <pfred1> dual drive axis?
[23:11:44] <Simonious> exactly
[23:11:54] <pfred1> yeah what you're doing isn't the best
[23:12:03] <Simonious> two geckos on that axes
[23:12:09] <Simonious> explain why and what would be the best
[23:12:11] <pfred1> you should fan that output out to two other outputs
[23:12:50] <Simonious> two geckos can't get step and direction from one set of pins
[23:12:51] <Simonious> ?
[23:12:55] <Simonious> did it that way with the other BOB
[23:12:57] <Simonious> worked great
[23:13:15] <pfred1> yeah you had gobs of current with your 2N2222 BOB
[23:13:43] <Simonious> well fine, but NONE of the axis are moving
[23:13:48] <pfred1> thosew buffer chips might not be able to supply enough current to trigger 2 optos though
[23:14:05] <pfred1> those optos might need 20ma a piece?
[23:14:09] <Simonious> fine, but th other two axis should be fine
[23:14:18] <Simonious> and again..
[23:14:25] <Simonious> I just went back to the other BOB and still no motion
[23:14:36] <pfred1> it depends on what htey are and what resistors are on them
[23:14:45] <Simonious> so.. I goofed something else up
[23:14:51] <pfred1> it sounds like it
[23:15:09] <Simonious> it's puzzling though.. the geckos aren't real tricky
[23:15:17] <Simonious> guess I'll sleep on it
[23:17:04] <pfred1> I hope you didn't somehow manage to kill the gecko inputs
[23:17:13] <Simonious> I have my doubts
[23:17:44] <pfred1> I can't see how the BOB could do it though
[23:18:21] <Simonious> I've got a spare driver I can set up with a solitary stepper for a sanity check later this week
[23:18:26] <pfred1> if anything it should fry before it fries anything else
[23:18:39] <Simonious> that's not what is up here
[23:18:58] <pfred1> that's the whole point of a BOB proteciton
[23:20:23] <Simonious> https://photos.google.com/photo/AF1QipOdqAAATJDHRZfQxYuc23nTka0h7yU_s-IRYkKn this is the box the drivers are in and they are still ganged through some of it's interface crap
[23:20:32] <Simonious> it may be time to gut this box and use it ONLY for power
[23:20:38] <Simonious> which is what should be going on anyway
[23:20:51] <Simonious> between the BOB and the geckos I don't need any other crap
[23:21:29] <pfred1> ah so this is a servo drive?
[23:22:22] <Simonious> yeah..
[23:23:13] <pfred1> the graphics on it are strange
[23:23:14] <Simonious> and I was using it last week with the old BOB, but no homing and two parallel ports and janky endstops
[23:23:37] <Simonious> trying to get it behaving sane and providing actual home
[23:27:37] <pfred1> yeah I don't do servos
[23:27:55] <pfred1> too advanced for me
[23:28:11] <Simonious> meh.. the geckos operate them as if they were steppers
[23:28:20] <pfred1> it appears that way
[23:31:05] <pfred1> CAUTION! Never put a switch on the DC side of the power supply! This will damage, if not destroy, your drive!
[23:31:27] <pfred1> Danger Will Robinson, danger!
[23:32:10] <Simonious> okay...
[23:34:07] <pfred1> if i tried to drive my lead screws 3,000 RPM they'd go shooting across my shop
[23:34:45] <Simonious> lets not do that then
[23:34:56] <pfred1> An example of using that formula with a 45kHz step pulse frequency and a maximum motor RPM of 3000:
[23:36:13] <pfred1> actually since i shortened them they've been better
[23:36:44] <pfred1> longer they really used to do the watusi though
[23:37:51] <pfred1> they're just cheap 1/2 X 10 TPI acme thread I bought off EMCO
[23:38:14] <pfred1> some's straighter than others
[23:39:08] * pfred1 has the fastest drawer slide machine in the east
[23:39:53] <pfred1> it will go a blistering 114 IPM before the PC tops out on step pulses
[23:40:38] <pfred1> mostly due to high drive setup timing
[23:41:03] <pfred1> 5,000ns
[23:41:35] <pfred1> well, 5,100ns for safety
[23:43:09] <pfred1> why don't they just tell you what wire gauge to use?
[23:43:20] <pfred1> Keep the power supply leads short and use the largest wire gauge that will fit in the terminals.
[23:43:32] <pfred1> I mean is it so hard ot put a number to it?
[23:48:08] <pfred1> If you have a choice, pick the oscilloscope.
[23:49:04] <pfred1> sage advise
[23:50:02] <Crom> whatta pain on #smoothieware
[23:50:17] <pfred1> I could go for a smoothie right about now
[23:50:25] <Crom> <wolfmanjm> ack-greo does what you are trying to do but is desigbed to do it i=without al lthe cruft you use...
[23:50:25] <Crom> <wolfmanjm> and FWIW I prefer you point people at the wiki where this is all docuemtned rather than the source code ok?
[23:51:11] <Crom> I looked in the freaking wiki and couldn't find what I was looking for... I found it in the source...
[23:51:33] <pfred1> one thing I never thought about with these CNC s is just how maddening the noise they make is
[23:51:43] <Crom> true
[23:52:15] <pfred1> the sounds my machine make are downright bizarre
[23:52:45] <Crom> they have a wiki page with all the configuration options... nothing on that page about the options available to the settings to those options
[23:52:55] <pfred1> it sounds like the soundtrack of a lousy B grade 50s sci fi movie
[23:53:42] <Crom> pfred1, make a gcode file to play main theme from starwars.. grep youtube for mario theme cnc
[23:53:49] <Crom> heh search
[23:54:08] <Crom> grok would be better
[23:54:11] <pfred1> grep gateway
