[00:00:01] <zeeshan|2> it weighs around 400lb
[00:00:10] <zeeshan|2> i can move it with the engine hoist
[00:00:13] <zeeshan|2> but who will come and by that?
[00:00:22] <bobo> over arm might be removed to get lathe in garage and then put back on
[00:00:25] <zeeshan|2> buy
[00:00:26] -!- rob_h has quit [Ping timeout: 240 seconds]
[00:00:28] <PetefromTn_> slap it on ebay
[00:00:33] <zeeshan|2> bobo i dont want to keep that overarm
[00:00:35] <zeeshan|2> i hate that style overarm
[00:00:37] <zeeshan|2> its pointless
[00:00:45] <zeeshan|2> it was pointful when they dont have a pendant
[00:00:50] <zeeshan|2> i removed it from the mikron too
[00:00:57] <PetefromTn_> your pendant will be more than enough and you can add one of those nicer chinese pendants off of it.
[00:01:06] <zeeshan|2> yea man
[00:01:11] <BitEvil> zeeshan|2: how much?
[00:01:11] <zeeshan|2> it's like 1/15 the weight
[00:01:21] <zeeshan|2> and so much more compact
[00:01:25] <zeeshan|2> BitEvil: for what?
[00:01:27] <zeeshan|2> the lathe?
[00:01:30] BitEvil is now known as SpeedEvil
[00:01:31] <SpeedEvil> yeah
[00:01:32] <zeeshan|2> or you wanna buy the motor? :D
[00:01:36] <PetefromTn_> LOL
[00:01:38] <zeeshan|2> hjaha
[00:01:42] <SpeedEvil> No, I wasn't meaning to buy anything
[00:01:45] <zeeshan|2> it was 4000
[00:01:48] <SpeedEvil> jesus.
[00:01:52] <SpeedEvil> That's insane.
[00:01:56] <Jymmm> Something actually useful (unlike glorified hot glue guns)... Water Transfer Printing https://www.youtube.com/watch?v=EdLObCu2JP0
[00:02:10] <Sync> huh?
[00:02:12] <SpeedEvil> zeeshan|2: It's actually got a useful selection of core bits?
[00:02:16] <Sync> 4000 is pretty good
[00:02:19] <SpeedEvil> zeeshan|2: 3/4 jaw chuck?
[00:02:24] <SpeedEvil> Sync: insane as in good
[00:02:32] <Sync> ah
[00:02:37] <zeeshan|2> SpeedEvil: 3 and 4 jaw chuck are aftermarket addons
[00:02:42] <zeeshan|2> these type come w/ a hydraulic chuck
[00:02:56] <SpeedEvil> I don't know what that is.
[00:02:57] <Sync> zeeshan|2: you can store the motor and stuff in your mitsu
[00:03:02] <zeeshan|2> SpeedEvil: you press a foot pedal
[00:03:03] <zeeshan|2> and the jaws open
[00:03:09] <zeeshan|2> Sync: hahahahahahah
[00:03:12] <zeeshan|2> poor mitsu is gone
[00:03:16] <zeeshan|2> i got $180 for it in scrap
[00:03:32] <zeeshan|2> i miss it, my first car
[00:03:33] <SpeedEvil> zeeshan|2: how do you handle centring?
[00:03:45] <zeeshan|2> SpeedEvil: you machine soft jaws everytime you wanna machine something
[00:03:52] <SpeedEvil> ah
[00:04:03] <zeeshan|2> (kind of annoying)
[00:04:12] <Jymmm> softjaws.com
[00:04:14] <SpeedEvil> It's designed for what - bar stock?
[00:04:23] <Wolf_Mill> or run parts in one shot
[00:04:32] <zeeshan|2> less questions
[00:04:34] <zeeshan|2> more action plz
[00:04:38] <zeeshan|2> what to remove from machine?
[00:04:40] <zeeshan|2> control cabinets?
[00:04:45] <zeeshan|2> those im not scrapping though
[00:04:52] <malcom2073> zeeshan|2: Everything you can
[00:05:09] * Jymmm slaps the shit out of zeeshan|2 (per his request for more action)
[00:05:10] <bobo> zeeshan what type of spindle motor does your lathe now have , servo type or D.C. or A.C. type ?
[00:05:14] <zeeshan|2> the control cabinets prolly weigh around 500lb?
[00:05:20] <zeeshan|2> boboss_: ac induction
[00:05:31] <Sync> rip the motor off
[00:05:34] <Sync> the housing
[00:05:37] <Sync> chuck
[00:05:38] <Sync> turret
[00:05:47] <zeeshan|2> the turret will be too hard
[00:05:50] <zeeshan|2> but that prolly weighs 1000lb
[00:05:50] <Sync> wat
[00:05:57] <SpeedEvil> sand off all the paint.
[00:06:01] <zeeshan|2> lol
[00:06:06] <Sync> drill speed holes
[00:06:08] <SpeedEvil> Drain the coolant.
[00:06:25] <Jymmm> more hole == more speed
[00:06:25] <zeeshan|2> chuck prolly weighs 80lb
[00:06:27] <zeeshan|2> not worth it
[00:07:11] <Sync> every gram counts
[00:07:38] <malcom2073> Sync: Only if the cops catch you
[00:08:09] <SpeedEvil> zeeshan|2: Did you actually need a lathe this big, or did you suffer an event?
[00:08:24] <Sync> it was cheap
[00:08:30] <SpeedEvil> :)
[00:08:32] <zeeshan|2> SpeedEvil: i need it
[00:08:41] <zeeshan|2> a get a lot of lathe jobs that i cant do
[00:08:50] <zeeshan|2> but will be able to do with this machine
[00:08:52] <SpeedEvil> Great then.
[00:08:53] <zeeshan|2> ill give you an example
[00:08:55] <PetefromTn_> I hear that
[00:09:01] <malcom2073> zeeshan|2: Go rent a fork lift
[00:09:03] <zeeshan|2> there were these fittings that a guy wanted 600 for
[00:09:05] <PetefromTn_> I have a BUNCH of lathe work I can do here
[00:09:05] <malcom2073> they're like... $500 a day
[00:09:19] <zeeshan|2> he was willing to pay $11.50 per piece
[00:09:19] <SpeedEvil> Do you have a power source that can run teh motor?
[00:09:24] <Sync> malcom2073: he did
[00:09:29] <zeeshan|2> it made no sense to do that on my old lathe
[00:09:33] <malcom2073> Haha, I meant a proper sized one
[00:09:35] <zeeshan|2> but with this machine i can put a bar puller on the tool holder
[00:09:37] -!- justanotheruser has quit [Ping timeout: 244 seconds]
[00:09:38] <zeeshan|2> and put a long bar
[00:09:44] <zeeshan|2> and walk away from the machine .
[00:09:54] <SpeedEvil> Bar feeders are cool
[00:09:57] <bobo> it is the perfect size lathe for a start up operation
[00:09:58] -!- md-2 has quit [Remote host closed the connection]
[00:09:59] <zeeshan|2> its not a bar feether
[00:10:01] <zeeshan|2> feeder
[00:10:03] <zeeshan|2> its a bar puller
[00:10:13] <zeeshan|2> bar feeders are really a waste of floor space
[00:10:14] * SpeedEvil doesn't understand the difference.
[00:10:18] <zeeshan|2> one feeds
[00:10:19] <zeeshan|2> the other pulls

[00:10:33] <zeeshan|2> bar feeder..
[00:10:41] <malcom2073> I've seen people using a cutoff tool to pull stock
[00:10:43] <SpeedEvil> Oh - the bar feeder is more than simply a steady-rest
[00:10:43] <malcom2073> that was kinda cool

[00:11:59] <PetefromTn_> those are SWEET
[00:12:05] <PetefromTn_> can't wait to be able to use one LOL
[00:12:05] <SpeedEvil> you need a steady-rest or something behind it or do you just mean for short bar?
[00:12:09] <Sync> zeeshan|2: not if you have thin stock that will have the death wobble
[00:12:23] <bobo> but a bar feeder can store many bars for thost 3 day part runs

[00:12:43] <PetefromTn_> gotta go to the store BB in a bit...
[00:12:43] <Sync> yeah and if you have a magazine loader you can run it for along time
[00:12:53] <SpeedEvil> How do you get rid of the chips?
[00:13:04] <SpeedEvil> Are there large chip compactors or something?
[00:13:21] <zeeshan|2> yea pete!
[00:14:42] <Sync> huh SpeedEvil
[00:14:47] <Sync> there is a chip conveyor
[00:15:14] <jdh> chip conveyor to the furnace
[00:15:37] <bobo> soon to be was a chip conveyor
[00:18:26] * SpeedEvil imagines a teeny chip compressor and bar extruder.
[00:19:42] <zeeshan|2> =-]
[00:20:14] <malcom2073> zeeshan|2: So why aren't you outside stripping parts?

[00:37:47] <zeeshan-mill> lol bobo
[00:37:50] <zeeshan-mill> itll be rural
[00:37:57] <zeeshan-mill> and bobo hahaha
[00:38:01] <zeeshan-mill> i got steel toes on :)
[00:38:06] <zeeshan-mill> i learned my lesson
[00:38:40] <Sync> don't drop the block
[00:39:04] <zeeshan-mill> hush you safety nazis
[00:39:21] <zeeshan-mill> !
[00:39:21] <malcom2073> don't block the box
[00:39:21] <zeeshan-mill> PetefromTn_, what kind of candy did you get me
[00:42:36] <Sync> mystery jelly beans
[00:42:49] <PetefromTn_> I got some skittles, some starburst, and some milk duds at the local dollar store for the kids. Also got some strawberry shortcake ice cream bars...
[00:43:02] <PetefromTn_> which do you wanna try first I will throw you some LOL
[00:45:33] <bobo> no blue M&M's ?
[00:46:04] <PetefromTn_> I like peanut M&M's

[01:23:40] <malcom2073> Yep
[01:23:42] <malcom2073> way to go Pete
[01:23:56] <PetefromTn_> heh It's all my fault..
[01:34:31] <furrywolf> so, in front of me I have a 1A fuse and holder, a 5A fuse and holder, a 100 ohm 10 watt resistor, a 51 ohm 1/4 watt resistor, two LEDs, 8 1n4004s, two 1683 lamps with holders, and a square of perfboard. any guesses what I'm building? :P
[01:35:26] <zeeshan|2> something dirty
[01:35:35] <furrywolf> no :P
[01:35:58] <Praesmeodymium> 2 dirty bridge rectifiers for some dc lights?
[01:36:06] <furrywolf> nope
[01:36:21] <zeeshan|2> im suprised youre not building something dirty
[01:36:24] <zeeshan|2> i thought it was some XXX light
[01:37:14] <furrywolf> the world's laziest/worst supercap bank charger. it charges through the light bulbs, with the LEDs indicating when there's a >Vf voltage difference, and the diodes to make a half-assed 2.8V double zener to clamp the voltage to the led current resistor. :)
[01:40:08] <furrywolf> I decided one Vf is the limit to how far the voltage can differ and still be OK to turn on the big switch. :P
[01:40:19] <furrywolf> I was originally planning a fancy comparator circuit... but I'm lazy.
[01:43:26] <furrywolf> also, the electronics store was out of red and yellow LEDs... but they did have pink and turquois! :P
[01:48:26] <furrywolf> sadly, even though I bought those two colors, I then went to radioshack to get the low-Vf red and yellow that I wanted.

[01:53:03] <Tom_itx> zeeshan-mill, what size chuck is it?
[01:53:24] <furrywolf> zeeshan|2: get your lathe installed?
[01:53:44] <PetefromTn_> damn these milk duds are good...;)
[01:53:55] <Tom_itx> one of my favorites
[01:54:12] <furrywolf> aren't you supposed to wait until AFTER halloween to eat all the kid's candy? :P
[01:54:28] <PetefromTn_> oh this isn't Halloween candy
[01:54:36] <PetefromTn_> this is just plain old candy candy
[01:55:06] <PetefromTn_> candy just for the sake of rottin your teeth out kinda candy :D
[01:55:23] <furrywolf> lol
[01:55:25] <Tom_itx> what's all that crap in front of the control on his lathe?
[01:55:40] <Tom_itx> the red thing is a chip trap i bet
[01:55:41] <furrywolf> I like pie, cheesecake, and some cookies... not a big candy fan.
[01:56:14] <Tom_itx> he better keep part of that conveyor
[01:57:52] <PetefromTn_> well there is no cheesecake so

[02:02:56] <zeeshan-mill> pete gimme some candy!
[02:02:59] -!- pinkfloyd has quit [Ping timeout: 240 seconds]
[02:03:09] <Tom_itx> zeeshan-mill, you better keep that chip conveyor
[02:03:13] <zeeshan-mill> why
[02:03:15] <PetefromTn_> here's some candy for ya
[02:03:17] <zeeshan-mill> its useless for me
[02:03:18] <Tom_itx> you'll be sorry if you don't
[02:03:31] <Tom_itx> one thing, it leaves a hole in the bottom
[02:03:32] <zeeshan-mill> itll collect in a bucket
[02:03:38] <zeeshan-mill> thats ok
[02:03:39] <PetefromTn_> telll me how you guys would machine this part on a 3 axis VMC....
[02:03:41] <zeeshan-mill> let em fall on the floor
[02:03:41] <zeeshan-mill> :P
[02:03:50] <Tom_itx> another, chips collect quicker than you think
[02:03:56] <PetefromTn_> http://imgur.com/sKwTpGa
[02:04:10] <Tom_itx> zeeshan-mill, along with all the coolant too
[02:04:11] <zeeshan-mill> tom no room
[02:04:22] <Tom_itx> who was the planner in this project?
[02:04:39] <zeeshan-mill> i never wanted to keep the chip conveyor
[02:04:40] <zeeshan-mill> from day 1
[02:04:43] <Tom_itx> make teh room bigger
[02:05:06] <zeeshan-mill> Tom_itx, in 2 years u will see!
[02:05:12] <zeeshan-mill> give me a chance till then :-)
[02:05:14] <Tom_itx> better not be that long
[02:05:40] <Tom_itx> i've run 8 spindle lathes.. they pump out the chips by the ton
[02:05:49] <zeeshan-mill> pete
[02:05:55] <zeeshan-mill> easy peezee!!
[02:06:03] <zeeshan-mill> lots of slotting!!
[02:06:03] <zeeshan-mill> :P
[02:06:04] <PetefromTn_> okay lets hear it
[02:06:15] <zeeshan-mill> rememer when i did the ls1 flange
[02:06:23] <PetefromTn_> I mean I have a plan here but I want to hear how you guys would do it
[02:06:23] <zeeshan-mill> i machined a negative of it out of aluminum
[02:06:43] <PetefromTn_> keep in mind I gotta face off BOTH sides and machine from BOTH sides
[02:06:50] <Tom_itx> PetefromTn_, drill the holes then profile it after bolting it down
[02:07:00] <Tom_itx> done deal
[02:07:20] <Tom_itx> that's exactly how i'd do it
[02:07:32] <PetefromTn_> how do you plan to surface both sides that way?
[02:07:48] <Tom_itx> surface as a pre op
[02:07:56] <Tom_itx> like we usually did
[02:08:13] <zeeshan-mill> symmetric flange
[02:08:13] <PetefromTn_> how?
[02:08:17] <zeeshan-mill> you can bolt it both ways
[02:08:22] <Tom_itx> hold it in some step jaws
[02:08:36] <PetefromTn_> this is my plan
[02:08:54] <PetefromTn_> I am going to cut off the parts from bar stock to just over length
[02:09:15] -!- Roguish has quit [Quit: ChatZilla 0.9.92 [Firefox 41.0.1/20150929144111]]
[02:09:41] <PetefromTn_> put the part in soft step jaws and face off top
[02:09:51] <PetefromTn_> drill and bore all the holes pockets
[02:10:01] <PetefromTn_> flip it over and face off the other side
[02:10:17] <PetefromTn_> then bolt it to a substrate plate to cut out the perimeter
[02:10:36] <PetefromTn_> but its too many steps
[02:10:51] <PetefromTn_> that is why I was going to ask you guys if you had a better way
[02:10:52] <Tom_itx> pre face it to thickness
[02:11:29] <Tom_itx> 1) drill the holes holding with strap clamps 2)bolt the holes and pocket & profile
[02:11:31] <Tom_itx> done
[02:11:34] <PetefromTn_> keep in mind that picture is just someone else's version ours is quite a bit different but the same procedures
[02:11:51] <PetefromTn_> not done that only does ONE side
[02:12:20] <Tom_itx> so flip it midstream and mill it some more
[02:12:23] <PetefromTn_> still gotta machine and surface the other side
[02:12:34] <Tom_itx> you got 4 ops no matter what
[02:12:47] <Tom_itx> waterjet
[02:12:51] <PetefromTn_> LOL
[02:12:53] <Tom_itx> then face 2 sides
[02:12:59] <Tom_itx> there's 3
[02:13:02] <Tom_itx> beat that
[02:13:19] <PetefromTn_> mine is 3 steps
[02:13:49] <PetefromTn_> first op first side in step jaws, face off, drill and pocket/engrave etc....
[02:13:53] <Tom_itx> you may want shoulder bolts
[02:14:25] <PetefromTn_> second op flip over and surface other side and machine pockets
[02:14:38] <PetefromTn_> third op bolt plate down to substrate and profile machine
[02:14:46] <Tom_itx> my way it's tied down during the whole profile pocket ops
[02:14:50] <Tom_itx> no movement
[02:15:02] <Tom_itx> you may want shoulder bolts
[02:15:03] <PetefromTn_> mine too
[02:15:11] <Tom_itx> no
[02:15:16] <Tom_itx> you profile separately
[02:15:20] <Tom_itx> from the pockets
[02:15:47] <PetefromTn_> the outside edge precision is not super critical
[02:16:02] <Tom_itx> mill away then
[02:16:04] <PetefromTn_> but the location of the holes and pockets sort of is... not really
[02:16:25] <PetefromTn_> but even if it was this procedure does not compromise that
[02:16:50] <PetefromTn_> but I am open to better suggestions
[02:16:55] <Tom_itx> we usually tried to use dowel pins whenever we could
[02:17:10] <Tom_itx> but if not, shoulder bolts
[02:17:24] <Tom_itx> unless the part was drawn from mylar prints
[02:17:35] <Tom_itx> which allow +-.030 right off the bat
[02:17:51] <PetefromTn_> the only other way I can see it working in two steps is...
[02:18:02] <Tom_itx> i did quite a few mylar with a digitizer
[02:18:04] <PetefromTn_> take your substrate plate
[02:18:19] <PetefromTn_> clamp the material down at the four corners
[02:18:34] <PetefromTn_> face off the part AROUND those clamps
[02:18:41] <PetefromTn_> or rather inside of them
[02:18:51] <PetefromTn_> drill, pocket, engrave
[02:18:53] <Tom_itx> face one side before you do that
[02:19:02] <Tom_itx> then you're done
[02:19:05] <PetefromTn_> bolt part down
[02:19:10] <PetefromTn_> then remove clamps
[02:19:13] <PetefromTn_> profile
[02:19:22] <PetefromTn_> yeah surface other side first
[02:19:26] <PetefromTn_> two steps!!
[02:19:27] <Tom_itx> that's basically what i said
[02:19:36] <Tom_itx> except i cleaned both sides
[02:19:50] <PetefromTn_> deck both sides in stepped jaws...
[02:19:53] <Tom_itx> clean one side then do what i said... 2 ops with an OP stop inbetween
[02:20:07] <Tom_itx> to move clamps
[02:20:33] <PetefromTn_> yup
[02:20:33] <Tom_itx> blow the threads out and bolt it down
[02:20:35] <PetefromTn_> should work
[02:20:43] <Tom_itx> we did that all the time
[02:20:52] <Tom_itx> but we tried to use dowel pins if possible
[02:20:56] <PetefromTn_> there are no threads except in the substrate plate
[02:20:59] <Tom_itx> even if they got cut off
[02:21:08] <Tom_itx> it locates the part better
[02:21:18] <PetefromTn_> dowel pins are not necessary if the part never moves
[02:21:22] <Tom_itx> add a dowelpin hole on the corner cutoff
[02:21:30] <Tom_itx> true
[02:22:06] <PetefromTn_> another thing I could do is leave tabs in the part off profile chunks to keep it together until the end of the program
[02:22:46] <PetefromTn_> gonna suck cutting all that steel around the profile tho
[02:22:52] <PetefromTn_> probably gonna wear out some cutters
[02:23:02] <PetefromTn_> gotta make a bakers dozen
[02:24:06] <Tom_itx> don't cut it all away..
[02:24:22] <Tom_itx> use a .375 cutter to profile
[02:24:24] <PetefromTn_> leave a thin film
[02:24:31] <PetefromTn_> was planning on that
[02:24:37] <PetefromTn_> .375
[02:25:02] <PetefromTn_> do you think a trochoidal toolpath full depth would be better or too slow
[02:25:04] <Tom_itx> you worried about the hole slugs, leave .003 and pop them out
[02:25:44] <PetefromTn_> can't gotta machine away the slugs probably due to a 3d profile I gotta cut there...
[02:25:46] <Tom_itx> how thick is it?
[02:25:51] <PetefromTn_> .5
[02:26:03] <Tom_itx> probably 2 passes
[02:26:13] <Tom_itx> depends on the machine
[02:26:26] <Wolf_> ghetto rig pressure washer + sand blaster to attempt to make water jet attachment for the mill IMO :P
[02:26:31] <Tom_itx> try not to go deeper than the cutter width
[02:26:40] <Tom_itx> on a pass
[02:27:39] <Tom_itx> 3d profile in an exhaust flange??
[02:27:51] <PetefromTn_> unfortunately
[02:28:01] <PetefromTn_> there is a longish taper on the holes in the center
[02:28:14] <PetefromTn_> unless I can find a suitable champfer mill that will cut it
[02:28:25] <Tom_itx> what angle?
[02:28:34] <Tom_itx> i have a 7deg cutter
[02:28:44] <PetefromTn_> dunno yet gotta cad it out LOL
[02:28:53] <PetefromTn_> its more than 45 tho
[02:28:54] <Tom_itx> wtf for?
[02:28:59] <Tom_itx> on the holes?
[02:29:17] <PetefromTn_> hey man I didn't design it LOL
[02:29:20] <PetefromTn_> just machining it
[02:29:37] <Tom_itx> cut em out then chamfer
[02:29:38] <PetefromTn_> supposed to smooth the gasses thru there or something
[02:29:49] <PetefromTn_> thats a big ass champfer
[02:30:00] <Tom_itx> sounds like some damn audio phool type
[02:30:01] <PetefromTn_> hang on lemme look at the drawing
[02:30:08] <PetefromTn_> hehe probably
[02:30:37] <Tom_itx> if he's that worried he should have them properly ported
[02:31:11] <PetefromTn_> he IS having them properly ported ;)
[02:33:00] <PetefromTn_> it's probably about 70 degrees or so.. I am missing some information I just realized LOL
[02:33:08] <PetefromTn_> gotta measure one at work tomorrow
[02:34:03] <Tom_itx> it's not shown in the one in the pic
[02:34:12] <Tom_itx> those look pretty straight
[02:34:28] <PetefromTn_> yup those are someone else's parts
[02:34:46] <PetefromTn_> ours is quite a bit different but the pic served to show what I am up against anyways
[02:35:23] <furrywolf> d'oh! I just realized each side of this needs a fuse holder, not just one.
[02:35:27] <Tom_itx> we made some from some really hard SS once... forget the alloy
[02:35:51] <Tom_itx> what a pita
[02:36:06] <furrywolf> during normal use, both sides are at 24V, with ~10kA available...
[02:36:13] <PetefromTn_> honestly if it were not for the tapered holes and the engraving and pockets on both sides these parts would not be viable for me to make...
[02:37:17] <Tom_itx> gonna weld em when you're done too?
[02:37:51] <PetefromTn_> hells yeah!

[02:38:01] <PetefromTn_> thats why I am making them we ran out LOL
[02:38:21] <PetefromTn_> plus we want to have our OWN version with our name on it etc.
[02:42:01] <Tom_itx> other than that it's a waste machining the top side
[02:42:19] <PetefromTn_> why?
[02:42:33] <Tom_itx> doesn't mate to anything
[02:42:39] <Tom_itx> nothing critical there
[02:42:44] <Tom_itx> just looks
[02:43:28] <PetefromTn_> yeah but that's the most important part!
[02:43:36] <fenn> sad but true
[02:43:37] <Tom_itx> pfft
[02:43:57] <Tom_itx> for marketing i suppose
[02:44:12] <Tom_itx> doesn't help performance one bit
[02:44:14] <fenn> nobody pays thousands of dollars for an ugly piece of metal
[02:44:28] <Tom_itx> if they get beat by it they might
[02:44:44] <PetefromTn_> well if it has a nice smooth shiny surface the air flowing across the motor from the radiator will create .000065 HP

[10:05:28] <archivist> yes
[10:06:20] <archivist> they stall when you abuse them or set incorrect settings or expect unreasonable speed from them
[10:06:24] <XXCoder> whats your pause time for em?

[10:06:35] <archivist> I dont pause them

[10:06:59] <XXCoder> no, its a setting at first configure for cnc device. hold on lemme get some info
[10:08:32] <XXCoder> ah got couple tihings wrong.
[10:08:36] <malcom2073> XXCoder: Nice, wonder how they'll respond
[10:08:43] <XXCoder> step time and space 2000 ns
[10:08:45] <XXCoder> not us
[10:08:59] <XXCoder> time and space,. time lord's dom ain
[10:09:03] <XXCoder> malcom2073: yeah lets see
[10:10:11] <archivist> the pulse durations are probably still some default value for me maybe 5000ns
[10:10:35] <XXCoder> I plan to try that next time. during work days its just not possible to do stuff lol
[10:10:47] <archivist> dont shorten too much some optos in the BOB and driver are slow
[10:12:05] <XXCoder> ok
[10:13:25] <archivist> then it can miss pulses thus causing stalling or plain failure to move
[10:14:02] <XXCoder> so its matter of finding sweet spot between time/space ns number and max speed and acceration?
[10:15:21] <archivist> max speed and acceleration are the usual fail points, back off a lot to keep within a sensible torque range of the motor
[10:15:36] <XXCoder> mines set to quite low

[12:33:58] <ganzuul> It's also a dimensionr eduction problem.
[12:34:36] <archivist> they like to take excess money for cam software at the moment while they can get away with it

[13:05:14] <ganzuul> ...They say in their marketing blab that it operates 'directly in cartesian space', so coordinate transformation or somesuch is simpler.
[13:05:42] <Wolf_> thats software
[13:06:10] <ganzuul> Yeah, I don't get why it's worth mentioning.
[13:07:20] <Wolf_> well, which is easier, telling the arm where to go, or needing to plot the full range of movement of the arm
[13:08:25] <archivist> what should the arm do if there are multiple ways of getting there

[15:22:55] <_abc_> cradek: about yesterday: a) version is 2.8.0-pre1-1122-someuuid b) I fixed the axis.py by hand to stop ignoring .ini param MIN_SPINDLE_OVERRIDE; this works okay. I set min_spindle_override = MIN_SPINDLE_OVERRIDE ... or 0.05; <- this prevents the spindle relay dropping when the scale is pulled to extreme left.
[15:23:09] <_abc_> The real bug will have to be found elsewhere, it is not in axis.
[15:23:11] <_abc_> Afaik.
[15:24:03] <_abc_> The load probe_paroport problem was solved as you said by removing the module and ensuring parport_pc is loaded

[15:50:12] <Wolf_> yeah, not rated the same as stepper eh
[15:51:04] <ssi> well typically servos are way faster than you need for a machine like that, so you probably ought to gear them down
[15:51:09] <ssi> and that multiplies the torque
[15:51:23] <ssi> those are probably 500W or more aren't they
[15:51:45] <Wolf_> 470w
[15:52:01] <ssi> yeah that's like 5/8hp

[16:21:45] <archivist> of/over
[16:21:50] <jdh> I had to find a fax for a refi a few years ago. pain in the ass

[16:32:11] <pcw_home> 7I39 is way too small
[16:34:10] <_abc_> jdh: It's easy to find. Walk into an electronics store, leave with a multifunction printer copier scanner fax.
[16:34:26] <_abc_> jdh: ~100EUR is entry level inkjet from big brands.
[16:34:30] <ssi> _abc_: cool, then what do you plug it into?
[16:34:31] <_abc_> Including HP
[16:34:38] <ssi> how do you hook that up to your cellphone? :P
[16:34:50] <_abc_> ssi: Cisco FXO to voip adapter of course ;)
[16:35:13] <ssi> bleh
[16:35:15] <_abc_> Cell phone fax is unlikely, but a POTS voip termination online is about $5/month if you shop around
[16:35:24] <ssi> yeah I've had them in the past
[16:35:29] <ssi> zero interest in dealing with that anymore
[16:35:38] <ssi> plus I don't have reliable internet these days either
[16:35:39] <ssi> hooray.
[16:35:41] <_abc_> You did say you need a fax number...
[16:35:49] <ssi> no, I needed to fax outbound
[16:36:09] <_abc_> The internet need not be reliable fax is always relayed over voip. The endpoint will not send it on until it's all in.
[16:36:44] <_abc_> Also alas there was the free fax by email service once upon a time. Free too.
[16:37:41] <ssi> it just seems stupid to buy a machine that scans a paper to an image to turn it into data which is then modulated to audio to be sent over voice over ip so that the audio is converted to data and transmitted over the internet to a pots gateway where it's converted back to audio to make a phone ring in new jersey so a machine can answer and listen to the audio which is demodulated into data which represents an image which is then printed on a printer
[16:39:07] <_abc_> Yes, but that is what they want
[16:39:16] <ssi> yes, because they're stupid
[16:40:50] <_abc_> If you say so.
[16:49:54] <CaptHindsight> I recommend that my online fax service. It's unstable but the payment system works flawlessly and there no way to contact us for support
[16:50:15] <ssi> a glowing recommendation :D
[16:50:57] <CaptHindsight> first half page is free, then all you need to do is prepay for the next 10 pages at $1.50 ea
[16:53:03] <CaptHindsight> wow, there is still a bunch of those services online
[16:53:17] <CaptHindsight> only they appear to charge by the month now
[16:54:31] <CaptHindsight> heh $16.95/mo and $10 sucker er em setup fee
[16:54:37] <ssi> :)
[16:56:17] <Wolf_> so, how do I figure out what voltage/current these BLDC servos can use?
[16:56:38] <ssi> what does the nameplate say?
[16:56:57] <Wolf_> just a part number
[16:58:20] <Wolf_> getting around ~0.27Ω on the coils and 783uH inductance, spec sheet says 250V max line to line
[17:00:15] -!- patrickarlt has quit [Remote host closed the connection]
[17:00:40] <ssi> spec sheet say anything about current?
[17:00:47] <ssi> peak/continuous rating?
[17:00:51] <CaptHindsight> load test them and monitor the temperature
[17:01:02] <CaptHindsight> if there's no data
[17:01:14] <ssi> treat them like 200VDC motors
[17:01:22] <Wolf_> 12A cont.
[17:01:36] <ssi> 120VAC recitfied and filtered for a supply feeding 200V servo drives
[17:01:55] <ssi> try to get some drives that'll do 200V max, 12V cont, 24A peak
[17:01:57] <ssi> or better
[17:02:04] <Wolf_> but thats a guess, winding are unknown
[17:02:06] <ssi> the amc BE20A25 is about right
[17:06:52] <Sync> yeah you can just DC load it and measure temp rise
[17:07:02] -!- Vq has quit [Remote host closed the connection]
[17:07:16] <Wolf_> not seeing any BE20A25
[17:08:31] <ssi> sorry be25a20
[17:08:40] <ssi> 25 is the peak current in amps, 20 is the max voltage in x10V
[17:08:49] <ssi> BE means brushless, encoder feedback
[17:09:12] -!- Loetmichel2 has quit [Ping timeout: 246 seconds]
[17:09:15] <ssi> the ones that end in AC have integral power supplies with a 120V IEC plug
[17:10:02] <ssi> but seriously, that drive plus a 500W servo is enough to run a small vmc :)
[17:10:08] -!- maurris has quit []
[17:10:26] <Wolf_> lol nice
[17:12:36] <Wolf_> think there is 3 of them on eBay, around $245 eh
[17:12:56] <ssi> the price fluctuates
[17:13:01] <ssi> they used to be cheap before zeeshan|2 bought them all
[17:14:51] <Wolf_> no good if its just B25A20AC ?
[17:14:59] <ssi> that's fine
[17:15:12] <ssi> might not have encoder feedback for velocity
[17:15:38] <ssi> your servos have hall sensors right?
[17:15:50] <Wolf_> yeah, hall + encoder
[17:15:52] <ssi> the B25A20AC can do hall velocity feedback

[17:19:09] <Wolf_> going lower voltage won’t work right?
[17:19:28] <ssi> AMC makes 200V drives and 80V drives
[17:19:35] <ssi> you could probably run those servos on 80V but I dunno how they'll perform
[17:19:54] <pcw_home> lower will work but limits you maximum speed
[17:20:12] <pcw_home> (and bandwidth a bit)
[17:20:16] <Wolf_> well, I think I have speed to spare lol
[17:20:35] <Wolf_> max is 6000rpm on these motors?
[17:20:42] -!- SpeedEvil [SpeedEvil!~quassel@tor/regular/SpeedEvil] has joined #linuxcnc
[17:22:07] <CaptHindsight> ssi: are those the drives that kept blowing up real good for zeeshan?
[17:22:10] <pcw_home> if you have the motor docs they will have V/1KRPM specified
[17:22:13] <ssi> CaptHindsight: yep :D
[17:22:30] <pcw_home> well z connected them in a bad way
[17:22:37] <ssi> I blew one up too
[17:22:51] <ssi> pro tip: make sure the power is disconnected and the light is off before you stick a screwdriver down in there to flip dip switches
[17:22:58] <ssi> cause it's perilously easy to short to the DC bus
[17:23:26] <pcw_home> That will do it...
[17:23:35] <ssi> the status light is fed off the dc bus so when it goes out the caps are discharged
[17:24:51] <Wolf_> odd no V/1KRPM listed

[17:27:39] <ssi> 12.5V/krpm
[17:28:06] <Sync> you can use our drivers Wolf_
[17:28:55] <ssi> god this is a nice datasheet
[17:28:58] <ssi> you're lucky to have this much data
[17:29:24] <Wolf_> yeah, except the windings are different in the motors I have
[17:30:01] <ssi> it'll get you close enough
[17:30:16] <ssi> any drive with 200V max voltage or better, 12A continuous will be fine

[17:31:05] <ssi> cute
[17:31:19] <Wolf_> looks like fun
[17:31:34] <ssi> I wonder how hard that'd be to adapt to drive stupid ass fanuc servos
[17:32:08] <ssi> Sync: your design?
[17:32:13] <Sync> yes
[17:32:19] <Sync> or rather, also
[17:32:23] <ssi> what eda software did you use to lay it out
[17:32:31] <Sync> that's eagle
[17:32:41] <ssi> are the eagle files up there?
[17:32:56] <ssi> oh there it is in hw
[17:32:57] <ssi> cool
[17:33:18] <ssi> crap I need to install eagle on this machine
[17:33:20] <Wolf_> gcc =/ can that be compiled with kiel?
[17:33:24] <ssi> gotta find my license files
[17:33:33] <Sync> stop using wrong compilers Wolf_
[17:33:41] <Wolf_> lol
[17:34:19] <ssi> sweet I put them in dropbox like a bawssss
[17:34:26] <Sync> there is no reason why it would not work but apparently it is an issue
[17:36:36] <ssi> Sync: mind if I fork that project and make some modifications to suit my needs?
[17:37:28] <Sync> if you tell me what you want to do/need I can tell you what's in the pipeline
[17:37:43] <ssi> i need to look at what it can do, looks like there's a ton of options
[17:38:06] <ssi> oh hm it doesn't do brushless DC motors does it
[17:38:28] <Sync> it does
[17:38:55] <ssi> does it have hall feedback for commutation?
[17:38:58] <ssi> I didn't see anything about hall inputs
[17:40:15] <Sync> nope, we don't need commutation feedback
[17:40:23] <ssi> really? how's that
[17:40:43] <Sync> well, we need an angle measurement device
[17:40:49] <Sync> and commutation is calculated
[17:40:58] <ssi> what does it do before encoder is indexed?
[17:41:03] <ssi> before there's an absolute angle known
[17:41:14] <Sync> rotor/encoder offset is constant
[17:41:23] <Sync> you do an autophase once
[17:41:24] <Sync> and it works
[17:41:53] <ssi> that might suit my needs then
[17:42:00] <ssi> how can I get ahold of pcbs?

[19:46:45] <ganzuul> Well both.
[19:47:35] <ganzuul> The faceplate on my lathe is made to much higher tolerances than the chuck. There's really a huge difference.
[19:49:06] <ganzuul> And since the lathe is very light, the chuck makes it shake a little.
[19:49:43] <ganzuul> That's with an 80mm chuck. I have a 125mm chuck in the mail.
[19:49:57] <CaptHindsight> I've managed to turn some toy machines into something with more use at times

[21:00:42] <XXCoder> yeah not centerness but angle
[21:02:09] <XXCoder> ganzuul: guy used special tool to find many possible problems, then he took out BIG block of alum, bottom is shinest alum I have ever seen.
[21:02:19] <XXCoder> he carefully makes sure its clean and adds gel
[21:02:28] <XXCoder> he took quite a while to grind
[21:02:37] <XXCoder> stops and checks once a while
[21:03:02] <XXCoder> at near final, he takes out smaller (but still big, 2 foot long, 1.5 foot wide) block of alum
[21:03:19] <XXCoder> uses something different (didnt see it clearly was busy)
[21:03:25] <XXCoder> grinds on it for short while
[21:03:25] <fenn> gel doesn't seem right because moisture causes granite to expand?

[21:09:35] <Sync> or just a real plate

[21:09:43] <Sync> it is far easier
[21:09:57] <Sync> although I did the 3 plate method with alu plates for fun
[21:10:00] <Sync> it really works

[21:17:47] <ganzuul> Shouldn't alu reach thermal equilibrium faster than cast iron? So the entire block expands, but the surface isn't warped?
[21:18:02] <ganzuul> Would make sense with what XXCoder said.
[21:18:11] <fenn> yes
[21:18:12] -!- HardWall has quit [Read error: Connection reset by peer]
[21:18:47] <fenn> they use aluminum for grinding the granite because you want the abrasive grains to embed into the lap and not the surface plate, so it has to be made of softer material
[21:19:41] <fenn> abrasive probably wouldn't embed into granite, but it might in cast iron
[21:20:02] <Sync> yup
[21:20:24] <Sync> I just used SiC for the al plates
[21:20:28] <Sync> but it also embeds
[21:20:36] <Sync> so they are of no use
[21:20:37] <Sync> still fun
[21:20:56] <fenn> you can use them as masters to make working plates
[21:21:22] <fenn> also you can make a radio out of coconuts
[21:22:16] <Sync> yeah or I can have them oxidizing away in a corner
[21:22:45] <ganzuul> The area/pressure equation assumes the area is a perfect plane...
[21:23:17] <fenn> what's the surface area of a mandelbulb?
[21:23:32] <ganzuul> Very much high.
[21:29:29] <ganzuul> The automatic generation of gages thing says the plates have to be of equal size. It doesn't say they have to be the same material, right?
[21:29:59] <ganzuul> So I could save a lot of effort by having 2 alu and 1 granite/iron.

[21:32:25] <Contract_Pilot> Let see 2 wrong motors so far
[21:32:46] <fenn> the walmart 48V PSU's arrived here too, they look like decent quality construction so far
[21:32:56] <Contract_Pilot> Not going to complain only got it for the drivers. Still awaiting 2 motr motors.

[21:38:42] <CaptHindsight> what's the best way to make a master surface plate when starting with nothing but a wooden table?
[21:38:57] <malcom2073> Lap three plates together
[21:39:23] <fenn> think really hard until you're in a universe that has more than just a wooden table
[21:39:29] <malcom2073> Heh that too
[21:39:44] <malcom2073> Sorry, didn't realize who asked :P
[21:40:38] <fenn> i'm thinking some optical interference method but i too dumb
[21:41:50] <ganzuul> Optical flats.
[21:42:06] <ganzuul> But they are for small things.
[21:42:06] <fenn> no something like an autocollimator
[21:42:50] <CaptHindsight> if using polymer concrete or polymer granite for machine base do you bother making the linear bearing contact areas as flat as possible or just shim (or similar) until the linear movements are flat and true?
[21:43:04] <fenn> you drive the autocollimator target around on your plate and it maps out the first derivative of the surface
[21:44:15] <fenn> CaptHindsight: you can inject moglice or some other granite powder+epoxy under the linear bearings while they're shimmed straight
[21:44:53] <fenn> thinner is better because epoxy is not nearly as stiff as granite
[21:45:12] <fenn> and it has different thermal coefficient
[21:45:39] <fenn> i'm assuming the filler has a higher epoxy/granite ratio than the bulk of the base
[21:45:46] <ganzuul> " The measurement resolution of a basic interferometer will still be limited by the wavelength of visible light. However more advanced techniques (such as looping the beam back and reflecting it twice) even allow nanoscale distances to be measured." - http://hackaday.com/2015/09/30/teeny-tiny-very-small-atomic-resolution-and-the-home-hobbyist/
[21:49:08] <t12> what malcom said
[21:50:22] <ganzuul> Optical... windlass.
[21:50:56] * ganzuul is just adding words together.
[21:51:08] <fenn> it sounded promising
[21:51:40] <ganzuul> Maybe a laser tweezer kind of thing?
[21:52:05] <CaptHindsight> what's the most foolproof way for someone to cast a flat a surface as possible polymer concrete or granite in the average garage?
[21:52:09] <ganzuul> Tune the phase of a standing wave.
[21:52:22] <Contract_Pilot> the 2 incorrect motors are left correct is right http://www.stevenrhine.com/wp-content/uploads/2015/10/Motors-Drivers-Walmart-1024x576.jpg

[21:55:44] <CaptHindsight> fenn: most won't have a precision straight edge
[21:55:50] <Sync> you can buy them
[21:55:53] <fenn> gotta get one
[21:56:17] <fenn> they're $65 for 3ft or $80 for 4ft
[21:56:39] <fenn> if you're more cost sensitive than that you shouldn't be using epoxy
[21:56:49] <Sync> yep
[21:56:58] <Sync> getting the right aggregate is expensive
[21:57:06] <Sync> and if you don't use it you can use straight epoxy
[21:57:09] <CaptHindsight> tough in a world where $10 for bearing is considered pricey
[21:57:22] <Praesmeodymium> Contract_Pilot: looking really closely at mine I see the mfg seal was broken befor I unscrew
[21:57:36] <Praesmeodymium> little tape job
[21:57:39] <fenn> CaptHindsight: i'm thinking about glass fiber reinforced concrete
[21:58:21] <fenn> my theory is that the supposed instabilities due to curing of reinforced concrete are actually due to thermal fluctuations and the difference in expansion coefficient between steel and aggregate
[21:58:38] <Sync> well, performance is expensive after all :/
[21:58:41] <Praesmeodymium> and i have a bent corneer
[21:58:56] <Sync> I wonder why all the people expect their cheap homebrew machines to actually work well
[21:59:11] <fenn> because sometimes cheap homebrew things work well
[21:59:47] <Sync> for a lot of things, sure
[21:59:57] <fenn> problem is most of the reprap and low cost 3d printers are designed poorly
[22:00:04] <Contract_Pilot> Bent corrent not bad you should see the large cap on mine looks like somone crushed it with pliers
[22:00:08] <fenn> there's no reason they have to be bad though
[22:00:18] <ganzuul> fenn: Not sure if quantum effects will allow an optical windlass to exist. Say you have circular polarization and...
[22:00:21] <ganzuul> actually
[22:00:39] <fenn> differential optical pressure
[22:00:52] <fenn> you know how a stepper motor is sort of like a vernier caliper?
[22:00:53] -!- andy__ has quit [Quit: Leaving]
[22:01:07] <ganzuul> There is a supercontinuum effect which might allow for a continously tunable laser.

[22:01:46] -!- sumpfralle has quit [Ping timeout: 240 seconds]
[22:02:25] <ganzuul> Quantum effects say you'd have to pick a discrete energy level, but in a supercontinuum (spectrally pure white light) that is not the case.
[22:03:50] <Loetmichel> *ha, got the notebook running with lubuntu 14.04.. even firefox runs (kind of) and abiword even runs smooth!... only todos are the audio and some better x driver for that sorry excuse of a "gpu"... and all that on a 366MHz pII with 544MB ram ;) -> http://www.cyrom.org/palbum/main.php?g2_itemId=15999&g2_imageViewsIndex=1
[22:03:51] <ganzuul> The laser self-modulates in the supercontinuum, but differential pressure, as you say, in addition with a laser mode such as circular polarization at two different wavelengths might, somewhere, allow for this optical windlass effect.
