[00:04:09] <malcom2073> zeeshan: If I thought I could cut under load at those speeds I'd maybe get one but... meh
[00:04:25] <zeeshan> you can
[00:04:27] <zeeshan> the cut im doing
[00:04:40] <zeeshan> isnt only putting 65 lb of feed force
[00:04:43] <zeeshan> *is
[00:04:46] -!- Loetmichel has quit [Ping timeout: 252 seconds]
[00:04:48] <malcom2073> I think that's getting above the torque dropoff of my steppers
[00:04:51] <malcom2073> in terms of rpm
[00:04:53] <zeeshan> oh
[00:05:17] <malcom2073> I had a really good idea for measuring that
[00:06:38] -!- AR__ [AR__!~AR@24.238.86.144.res-cmts.sth2.ptd.net] has joined #linuxcnc
[00:06:44] <malcom2073> Get a digital scale on a hard spring, and run into it until it skips steps
[00:06:59] <zeeshan> haha
[00:07:01] <zeeshan> that'd be awesome
[00:07:02] <malcom2073> should give me an idea at what feed force I skip for different speeds
[00:07:03] <zeeshan> and simple..
[00:07:56] <malcom2073> I'll see if I can find a cheapie that'll read out max weight or something, cause it'll hit it and then immediatly go off when it skips
[00:08:33] <zeeshan> you gave me an idea
[00:08:42] <zeeshan> you could get a spring of known spring rate
[00:08:49] <zeeshan> and just put a dial indicator and measure how much it deflects?
[00:09:03] <malcom2073> That may be easier, possily also cheaper
[00:09:06] <malcom2073> Well
[00:09:08] <yasnak> Laurenceb: yeah it does. depends on the machine too. You want to strike a balance on gaining productivity by stacking multiple parts to use the machine to its best ability.
[00:09:17] <malcom2073> Depends on how much a known spring rate spring costs that can do 60-100lbs
[00:09:30] <zeeshan> i think a valve spring might be too tense
[00:09:34] <zeeshan> *stiff
[00:09:35] <malcom2073> Or I could figure out the spring weight with a scale and a measuring tape
[00:09:36] <malcom2073> ?
[00:09:41] <malcom2073> spring rate*
[00:09:59] <zeeshan> thats how we measured spring rates in a lab
[00:10:03] <zeeshan> but requires known masses
[00:10:10] <zeeshan> its easier just to buy a spring with a known spring rate
[00:10:14] <zeeshan> valve springs are really good for that
[00:10:23] <zeeshan> most of the v8 stuff is documented
[00:10:31] <zeeshan> or next time you're ordering from mcmastercarr
[00:10:33] <zeeshan> grab one :)
[00:10:36] <malcom2073> Heh
[00:10:43] <malcom2073> I have a random assortment, wonder if any of them have model numbers
[00:11:13] <zeeshan> what the hell
[00:11:20] <zeeshan> 4" Overall Length 1.937" 0.312" 2.73" 597.00 470.00 1 96485K384 13.56
[00:11:25] <zeeshan> 13.56 bucks!
[00:11:36] <zeeshan> actually that one is too stiff
[00:11:39] <zeeshan> 470lb/in
[00:11:45] <malcom2073> hah
[00:12:43] <malcom2073> Still, looks like I may be able to put together something for under $50 to do this
[00:12:53] <zeeshan> dial indicator you have
[00:12:54] <zeeshan> 1"?
[00:13:10] <malcom2073> a lot less than that, and spring loaded so that's no good
[00:13:26] <malcom2073> What am I talking about, table shouldn't bounce back
[00:13:39] <zeeshan> not unless it skips a step =D
[00:13:58] <malcom2073> Eh, the bounce back may be acceptable tolerance
[00:14:01] <malcom2073> in terms of measuring force
[00:15:54] <malcom2073> Couldn't I use a spring scale?
[00:15:55] -!- andypugh has quit [Quit: andypugh]
[00:15:59] <malcom2073> The kind that has the slider to register max force?
[00:16:05] <zeeshan> ya
[00:16:09] <zeeshan> but im not sure where you'd wedge it
[00:16:20] <malcom2073> Knee mill, tons of places :)
[00:16:23] <malcom2073> I'd make a bracket for it
[00:17:01] <malcom2073> hmmm
[00:17:11] <malcom2073> Once you get into the 50+lb range, the spring scales get expensive lol
[00:17:39] <enleth> what's the point of a vertical lathe with a top-mounted, downwards-pointing headstock? just stumbled upon such a machine on an auction
[00:24:47] <zeeshan> enleth: the chips fall straight down
[00:24:48] <zeeshan> :P
[00:25:07] <malcom2073> zeeshan:
http://www.mcmaster.com/#9630k7/=12542se
[00:25:20] <zeeshan> that'd work
[00:25:22] <zeeshan> but jeez 22 bux
[00:25:25] <zeeshan> its a damn spring!
[00:25:33] <malcom2073> 2" OD heh
[00:25:39] <malcom2073> 7" long
[00:25:40] <malcom2073> it's big
[00:26:32] <zeeshan> enleth think about it to yourself! :P
[00:27:37] <enleth> zeeshan: sounds weird for the only advantage
[00:27:44] <zeeshan> thats not the only advantage
[00:27:51] <enleth> that's what I figured
[00:28:20] <zeeshan> hint
[00:28:22] <zeeshan> gravity
[00:28:29] <enleth> loading it with stock must be a PITA, holding it up until the chuck engages (this one seems to have a collet chuck)
[00:28:39] <zeeshan> its easier
[00:28:44] <enleth> unless there's some kind of mechanism that props it up
[00:28:59] <zeeshan> imagine a 20" part
[00:29:02] <zeeshan> 8" thick
[00:29:11] <zeeshan> do you really want to load that sideways?
[00:29:26] <zeeshan> vertical also means it can built more rigid
[00:29:33] <enleth> with a crane, sure
[00:29:34] <zeeshan> because you can support about 270 degrees around the spindle
[00:29:47] <enleth> OK, that makes sense
[00:29:50] <zeeshan> and the lathe thing i can think of is footprint
[00:29:59] <zeeshan> im a regular lathe sitting up
[00:30:02] <zeeshan> imagine how much space you save
[00:30:19] <zeeshan> we had 22-25 of those sl5 la thes
[00:30:21] <zeeshan> *lathes
[00:30:33] <zeeshan> they had a conveyor that went throu them
[00:30:44] <zeeshan> and it'd pick up the part, place it inthe chuck and machine away
[00:31:10] <zeeshan> but i agree with you, i personally found it a pain in the ass to fix things on it
[00:31:20] <zeeshan> even loading parts manually was annoying
[00:31:36] <zeeshan> vl5 not sl5
[00:32:57] <enleth> yeah, a conveyor setup seems to be an ideal use for those
[00:33:18] <enleth> but definitely not doing short runs with manual tending

[01:02:53] <zeeshan> hm
[01:02:59] <zeeshan> i still gotta machine thbis part
[01:03:06] <zeeshan> and i always have had trouble doing this type of work
[01:03:19] <zeeshan> especially when its large, and cant fit in my vise along the length

[01:10:27] <zeeshan> http://i.imgur.com/QRhWipp.png
[01:10:38] <zeeshan> the 60 degree angle
[01:10:41] <zeeshan> how do i hold that?
[01:11:11] <zeeshan> put a 30 degree angle in the vise?
[01:11:33] <cradek> heh 60.000
[01:11:42] <zeeshan> yes 60 degrees is what i want to do
[01:12:08] <zeeshan> | xxxxxxxxxxx |
[01:12:11] <zeeshan> | are my vise jaws
[01:12:15] <zeeshan> i can't hold the part like that
[01:12:21] <zeeshan> because the vise jaws only open 8"
[01:12:44] <zeeshan> which means i cant just angle the part and hold it at it's end (which is how i usually do it)
[01:13:05] <zeeshan> i need to hold the part perpendicular to the jaws,,, but i dont know how to hold it!
[01:13:11] <cradek> it's 19.5 inches long? looks tricky.
[01:13:37] <zeeshan> i need to set it up twice
[01:13:41] <zeeshan> cause i only have 15.7" travel
[01:14:01] <zeeshan> i'd feel so much better if i could set this type of stuff up -- it gives me trouble always

[01:14:27] <zeeshan> http://www.mini-lathe.com/Mini_mill/Accessories/Vises/Angle_vise.jpg
[01:14:29] <zeeshan> is this the only way?
[01:14:40] <zeeshan> the way i have it currently planned
[01:14:43] <zeeshan> is holding the part square inthe vise
[01:14:46] <zeeshan> and just using an angle tool path
[01:14:48] <zeeshan> but it'll take forever
[01:15:06] -!- Frank__13 [Frank__13!~frank___@host134.190-226-76.telecom.net.ar] has joined #linuxcnc
[01:17:36] <cradek> you could make several short fixture pieces that hold it at the right angle
[01:17:47] <cradek> little cradles for it to sit in
[01:18:01] <cradek> each one would be short enough to fit on the sine bar in your vise
[01:18:20] <cradek> or whatever you have that will give you this angle - I have a nice 30-60-90 triangle
[01:18:31] <zeeshan> i have a 45 and 30/60
[01:18:38] <zeeshan> both are 90's at the other end
[01:18:46] <zeeshan> but only got 1 of each
[01:18:49] <cradek> then cradle it in several, indicate, and clamp it down
[01:19:05] <zeeshan> but i cant clamp it down
[01:19:06] <cradek> yeah just use one to cut the angle you need in some scrap
[01:19:10] <zeeshan> because it'd be clamping on the edges of the part
[01:19:27] <cradek> yes you'll have to plan ahead - maybe do this surface first
[01:19:45] <cradek> or mount it to the fixtures with those screw holes
[01:20:42] <cradek> whatever you do, the solution will involve cutting this that aren't this part - think along those lines
[01:20:51] <cradek> er, things that aren't
[01:21:14] <zeeshan> hehe
[01:21:29] <zeeshan> looks like doing a ramp tool path in the xy plane is the quickest
[01:22:40] <zeeshan> poor end mill will be seeing a lot of pluging
[01:22:47] <Tom_itx> whassup?
[01:22:54] <unfy> ordering some parts for second cheap mill build sometime in the future :D
[01:23:19] <zeeshan> Tom_itx: cradek was suggesting on ways to mill the angle on the part
[01:23:30] <Tom_itx> what part?
[01:23:35] <zeeshan> http://i.imgur.com/QRhWipp.png
[01:24:03] <Tom_itx> just buy a $$$$ angle cutter :D
[01:24:08] <zeeshan> lol
[01:24:31] <unfy> 1.75" 60deg cutter ? ouch
[01:24:34] <Tom_itx> 5 axis would be easy
[01:24:52] <zeeshan> the more i look at it
[01:24:55] <Tom_itx> i had a cutter but it was a lesser angle
[01:25:03] <zeeshan> the more im thinking plunging with my 3/4" cutter would be easiest
[01:25:10] <zeeshan> with a nc tool path
[01:25:22] <cradek> then what, file it flat?
[01:25:26] <zeeshan> no no
[01:25:29] <cradek> no idea what tolerances you're working with here
[01:25:34] <zeeshan> 3 thou
[01:25:37] <cradek> I assume you don't mean 60.000 degrees
[01:25:43] <zeeshan> linear tolerance
[01:25:47] <zeeshan> haha idont
[01:25:53] <zeeshan> was a quick drawing :)
[01:25:58] <Tom_itx> use a 1" ball nose and the cusp height would be alot wider

[02:00:38] <BeachBumPete> it does have a nice size 2 car garage

[02:02:24] <Tom_itx> for what?
[02:02:27] <BeachBumPete> so I think what I will do is build a large shed/shop building out back for like just my woodworking tools
[02:02:33] <zeeshan> 25 thou step over
[02:02:35] <zeeshan> with a ball nose
[02:02:42] <Tom_itx> you could rig a sine plane
[02:02:57] <Tom_itx> try roughing with a bull nose and finish with that little cutter
[02:03:02] <BeachBumPete> so the garage will be JUST for my metalworking and Tig welding
[02:03:07] <zeeshan> oh i see what you mean
[02:03:13] <zeeshan> rough away with steps
[02:03:15] <Tom_itx> yes
[02:03:25] <Tom_itx> .1 step over or such
[02:03:30] <Tom_itx> maybe a bit less
[02:03:42] <Tom_itx> 1" cutter or so
[02:03:53] <zeeshan> im thinking i might just invest the time in making a proper jig

[02:06:21] <zeeshan> whats stopping it from rotating?
[02:06:26] <zeeshan> tightening that bolt where it pivots?
[02:06:37] <Tom_itx> you should drill pins at some angles like 60 45 etc
[02:07:00] <Tom_itx> put a machinist jack under the front edge
[02:07:17] <zeeshan> asking for trouble :P
[02:07:31] <Tom_itx> get a 5 axis
[02:07:36] <zeeshan> lol
[02:07:39] <zeeshan> solution to everything
[02:07:40] <zeeshan> 5 axis!
[02:07:45] <Tom_itx> hah true
[02:07:47] <zeeshan> :D
[02:08:00] <zeeshan> that was the joke we pulled at work
[02:08:03] <Tom_itx> i'd go with the bull nose/ angle cutter combo
[02:08:12] <zeeshan> i will if i can't some up with a fixture
[02:08:18] <zeeshan> if i make a fixture
[02:08:21] <zeeshan> it'll be flexible
[02:08:23] <zeeshan> otherwise no point

[02:08:57] <Tom_itx> i could also apply that excuse to a 5 axis

[02:09:03] <yasnak> there, now three machines running 24/7.
[02:09:37] <zeeshan> why is it so dark in the shop yasnak
[02:09:40] <Tom_itx> it also wouldn't require a P2 for that cut
[02:09:44] <Tom_itx> your solution would
[02:09:50] <yasnak> because its night haha
[02:09:54] <zeeshan> =P
[02:10:04] <yasnak> the back swiss shop runs unattended from 5pm - 5am

[02:11:36] <yasnak> thanks bro
[02:11:37] <yasnak> i'm good
[02:11:42] <Tom_itx> and that's just for not having their posters displayed
[02:12:14] <yasnak> you mean i need to put the interlocks on again? sigh

[02:15:37] <yasnak> tom
[02:15:38] <yasnak> as did i
[02:16:00] <yasnak> I've never met such interesting people then at that OSHA class
[02:16:24] <Tom_itx> there were all sorts at mine
[02:16:57] <yasnak> I would be worried about some people's safety programs after meeting some haha
[02:17:05] <yasnak> Two day class?
[02:17:07] <Tom_itx> most were monkey machinists but there were a few healthcare personell etc
[02:17:18] <Tom_itx> yea

[02:19:53] <yasnak> this was a question they answered too
[02:20:05] <yasnak> i think it goes towards paying for the program as well...
[02:23:01] <Tom_itx> https://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=NEWS_RELEASES&p_id=30702
[02:23:07] <Tom_itx> i think that was one of em
[02:25:05] <Tom_itx> nobody likes em but they do a good service for employees
[02:26:45] <Tom_itx> Penalties collected from businesses through OSHA violations go to the U.S. Treasury’s general fund as required by the Section 17. Penalties of the OSH Act of 1970. Fines are not used to directly fund OSHA activities.
[02:27:25] <Tom_itx> there's your answer
[02:27:43] <zeeshan> lol
[02:28:25] <yasnak> well i totally forgot everything
[02:28:37] <yasnak> good thing i think i remember where my little class training manual is
[02:28:47] * Tom_itx pulls yasnak's osha10 card for reevaluation
[02:28:49] <yasnak> i think
[02:29:27] <yasnak> Went with my boss. I think we both partied hard the nights before as it was nearly like vacation haha
[02:32:12] <Tom_itx> i will tell you that if they show up, they DO NOT issue warnings
[02:32:28] <zeeshan> hah
[02:32:31] <zeeshan> osha is boss
[02:33:21] <Tom_itx> and they fine for each occurance so if you and your buddy are caught with no safety glasses that's 2 instances
[02:33:29] <Tom_itx> X 7k minimum
[02:35:18] <zeeshan> tom
[02:35:21] <zeeshan> i think i figured it out..
[02:35:37] <Tom_itx> i had that done 30 min ago
[02:35:55] <zeeshan> i forgot that my mill head tilts :P
[02:36:00] <zeeshan> :)
[02:36:14] <Tom_itx> yeah but that takes time and time to get it straight again
[02:36:17] <zeeshan> no
[02:36:21] <zeeshan> i dont have to dial it in
[02:36:26] <zeeshan> it's held in by precision pins
[02:36:30] <zeeshan> @ 0 location
[02:36:33] <Tom_itx> at 60 deg?
[02:36:47] <zeeshan> 60 degree isnt critical
[02:36:52] <zeeshan> as long as it's same for the two wedges
[02:36:59] <Tom_itx> if you're set on having a 2nd op go for it
[02:37:02] <zeeshan> eyball centric
[02:37:09] <zeeshan> i also trhought of another way..
[02:37:13] <zeeshan> but it involves more work
[02:37:40] <Tom_itx> setting up an extruder?
[02:37:43] <zeeshan> it samazing how much work can be done in the shower.

[02:38:12] <zeeshan> ^ thats my shower thought
[02:38:13] <zeeshan> lol
[02:38:45] <Tom_itx> that would work ok but it still adds a 2nd position
[02:38:56] <zeeshan> what do you mean second position
[02:40:19] <Tom_itx> you still have to drill holes and slot the piece
[02:40:35] <zeeshan> thats easy peezee
[02:40:35] <zeeshan> :P

[02:51:44] <enleth> can't decide if the e-stop on a laser cutter should cut HV supply power only or LV for steppers and control as well - what do you think?
[02:52:19] <djdelorie> if it's an emergency, kill everything
[02:52:33] <enleth> the steppers are a joke and won't really damage anything even if the machine loses position, they just make funny noises when they bump against physical stop
[02:53:45] <enleth> it does make sense, though, that the e-stop should kill them as well - someone might want to use it when they hear those funny noises and realize they hit the end of the axis

[02:57:40] <enleth> this just takes the cake

[03:15:05] <enleth> os1r1s: noticed already
[03:15:16] <enleth> that's not a reason not to add one
[03:15:26] <enleth> I'm rewiring that piece of crap anyway
[03:17:03] <os1r1s> enleth I think its a bit pointless to have one on an LC anyway
[03:17:40] <os1r1s> enleth I assume you are swapping it to linuxcnc?
[03:17:58] <enleth> not yet, but that's a possibility
[03:18:39] <os1r1s> They have an aftermarket electronics kit for those that makes it much better
[03:19:43] <enleth> the tube cracked, I decided to replace the stock cooling system with a closed circuit one, then one thing lead to another and now I'm replacing all the electrical and HV control wiring
[03:20:44] <enleth> the new tube is already in
[03:20:47] <os1r1s> enleth It was one like this, but a bit cheaper ..
http://www.lightobject.com/AWC608-Commercial-DSP-CO2-Laser-Engraving-Cutter-Controller-P321.aspx
[03:21:07] <enleth> I've seen that one
[03:21:11] <enleth> a bit pricey, though
[03:21:19] <unfy> $300 on the machine, $500 on the upgrades, spend $750-$800 on something better to begin with ? j/k
[03:21:49] <enleth> for that price, I could get a mesa set and use some random stepper drivers I have lying around
[03:23:16] <enleth> unfy: a friend got EU funding for his startup a year ago and bought this cutter, then brought it in, so I'm in no position to complain
[03:23:50] <unfy> indeed
[03:24:25] <enleth> and while it worked, it was rather useful, if a bit finicky
[03:25:45] <enleth> it was two weeks out of warranty when the tube failed (it's not like that would be covered anyway), so he just let me play with it while I replace the tube
[03:26:30] <enleth> the chassis is OK, nice thick powder coated sheet metal
[03:27:31] <enleth> the axes aren't that bad either, stiff enough to move a mirror/lens armature
[03:27:56] <enleth> it's just the wiring that's shit
[03:28:12] <enleth> and how they placed the control panel and power switch under the cover
