[00:37:47] <trentster> RootB: what is your use case for making it stiffer, you want to cut wood faster?
[00:39:06] <trentster> also do you have version 1 or 2 of the Shapeoko?
[00:53:06] <CaptHindsight> http://pumpingstationone.org/wp-content/uploads/2013/10/inventables_Shapeoko_v21068.jpg
[00:54:00] <CaptHindsight> it's just not a rigid design
[01:10:57] <trentster> nope, also the z axis itself has too much deflection, and almost no rigidity
[02:20:46] <Deejay> moin
[02:25:42] <trentster> moin Deejay
[02:26:40] <trentster> Anyone here ever made a lowish powered DIY laser CNC machine - I am looking to make something primarily for etching acrylic.
[02:26:50] <trentster> Any thoughts on DIY build vs buy ready made?
[02:28:41] <MrSunshine> more fun to dyi ? =)
[02:28:54] <MrSunshine> but requires a skillset =)
[02:29:11] <archivist> learn while doing
[02:29:17] <trentster> sure - but which is more cost effective and will you land up with a better spec machine going that route
[02:29:38] <archivist> yes/no/impossible to say
[02:30:08] <MrSunshine> i do not regret building my router myself, learned alot of metalworking etc while doing it =)
[02:30:12] <trentster> What Watt Laser would I need for etching and acrylic cutting( multiple passes ok)
[02:30:29] <MrSunshine> and how materials behave under stress ... damn steel to be soft
[02:30:49] <archivist> the wattage depends on colour of material
[02:31:10] <Jymmm> no comment
[02:31:34] <trentster> any recommendations from a laser perspective - could I get away with non CO2 laser for this stuff. I really don't sallivate over the idea of aligning tube optics
[02:31:55] <trentster> archivist: assume clear acrylics
[02:32:25] <archivist> I dont have one, I would have to google
[02:34:05] <Jymmm> archivist: Need a strip/pipe heater? http://www.ebay.com/itm/White-Exhaust-Thermal-Warp-Tape-Stainless-Electric-Heating-Band-Ties-1M-SP21/131586316364
[02:34:48] <archivist> no
[02:34:53] <archivist> I need a car
[02:35:02] <Jymmm> mill one?
[02:35:03] <trentster> This is what I have spare lying around the office: lots of 10 series t slot extrusion, quite a lot of 12mm wide linear rail with mini linear guideway/blocks and a couple of nema 17's and cogs and belts
[02:35:28] <Jymmm> archivist: OH I know.... 3d print one =)
[02:35:34] <trentster> which to me is pretty far along the way towards a buildable laser machine.
[02:37:41] <Jymmm> archivist: what happened to your car?
[02:38:52] <trentster> Also you guys in the US - what are the current 3 biggest "urban workshop" business in the US. The urban workshop website says "Urban Workshop is the 3rd largest DIY workshop and makerspace in North America" any clue what the other 2 are?
[02:39:15] <archivist> Jymmm, it dies a year ago, been borrowing a van
[02:39:20] <archivist> died
[02:39:38] <Jymmm> archivist: OH that sucks.
[02:40:50] <Jymmm> archivist: I bought 20yo civic off craigslist for $1400, looked ugly but actually ran great.
[02:41:29] <Jymmm> Really just needed some TLC.
[02:42:00] <trentster> If anyone reads my question in the channel and knows the answer please ping me - much appreciated
[02:42:01] <archivist> when working about 1 day a week that is expensive
[02:43:06] <Jymmm> ah, yeah
[02:44:30] <archivist> trentster, the problem is different mixes and colours will heat/melt in different ways with a laser
[02:45:00] <Jymmm> This is kinda funny, kinda sad... http://www.ebay.com/itm/Self-Locking-Contact-Clear-Cover-Red-Emergency-Stop-Push-Button-Switch-/321346624818
[02:45:30] <trentster> archivist: I am not talking about that question, I am talking about the US maker spaces question above
[03:56:28] <Tom_itx> archivist, get an old cooper and rebuild it
[03:57:59] <archivist> a cooper is a person making casks
[03:58:08] <Tom_itx> well a mini
[03:58:59] <archivist> Minis cannot carry stuph in the manner that I would like
[03:59:44] <archivist> the older ones rot away too
[04:00:21] <Tom_itx> there was a guy here that restored an old one.. it turned out rather nice
[04:00:42] <Tom_itx> always ran hot though
[04:01:21] <archivist> I can no longer put cars in the garage to fix them, 2 lathes, Milling machine and a CMM
[04:01:30] <archivist> oops 3 lathes
[04:19:58] <enleth> archivist: you know you've got a problem when you're losing count of the lathes in your garage
[04:21:28] <archivist> and kitchen :)
[05:06:07] <XXCoder> man
[05:06:13] <XXCoder> fucked up bad at work
[05:06:35] <XXCoder> one machine dont change to first tool when ran, and I forgot to change tools to that one before running
[05:06:45] <XXCoder> destroyed a cat50 chuck :(
[05:06:54] <XXCoder> could be worse, but not much worse
[05:13:41] <enleth> XXCoder: what about the spindle?
[05:13:51] <XXCoder> its fine, like i said it could be worse
[05:14:04] <XXCoder> chuck went down to side of fixture, and went up against it
[05:14:14] <XXCoder> it tightened way past its specs and cracked
[05:14:23] <XXCoder> 3 jaws smashed together
[05:14:46] <XXCoder> fixture itself have massive gouge on it, and one support for part is bent
[05:15:08] <XXCoder> kurt jaws dont seem to be touched, but I definitely would have checked it over before reset
[05:15:26] <XXCoder> part that was on it was destroyed of course
[05:15:31] <enleth> tbh, while the next worst thing - spindle damage - would require substantially more bad luck, it would have been much worse
[05:15:53] <XXCoder> just glad it didnt smash into table
[05:25:13] <XXCoder> enleth: ever happened to you?
[05:27:00] <archivist> almost every one has broken something
[05:28:03] <enleth> XXCoder: no, but I've seen a mill snap off an iso40 to B22 adapter
[05:29:00] <XXCoder> archivist: just hoped to never have tool crash
[05:29:00] <_methods> did you knowck the fixture out of whack?
[05:29:08] <XXCoder> _methods: it got pushed off
[05:29:13] <_methods> ouch
[05:29:16] <XXCoder> and jammed with chuck gouging it
[05:29:23] <_methods> if you run cnc machines you'll crash at some point
[05:29:26] <_methods> just learn from it
[05:29:30] <XXCoder> it was X axis error that stopped it
[05:29:31] <enleth> the tension in the adapter that got released when it finally gave in was enough to shift the whole mill out of position by a visible distance
[05:30:02] <XXCoder> _methods: thanks. hopefully i will surive the roast from boss
[05:30:03] <_methods> guy at work crashed a lathe so bad one time he cracked the turret
[05:30:08] <_methods> he got fired
[05:30:14] <XXCoder> I accept it as it was my own dumb fault
[05:30:23] <XXCoder> I hate that okuma
[05:30:39] <_methods> pick the machines you hate the most and master them
[05:30:42] <XXCoder> turret forgot what it is?
[05:31:05] <_methods> what?
[05:31:10] <XXCoder> _methods: yeah been running okuma often its mostly fine
[05:31:33] <XXCoder> I just hate the fact that it can't change tool at beginning of program
[05:31:33] <_methods> i always go for the machines no one else wants to run
[05:31:35] <XXCoder> no idea why
[05:31:48] <archivist> turrets are boring
[05:32:11] <XXCoder> enleth: whats turret?
[05:32:22] <_methods> it holds the tools in a lathe
[05:32:28] <XXCoder> ouch
[05:32:30] <XXCoder> expensive
[05:32:34] <_methods> umm yeah
[05:33:05] <XXCoder> I remember reading about one guy who hit lathe so hard the umm chuck? broke off when it was spinning very fast
[05:33:13] <XXCoder> it spun around inside machine. machine was totaled
[05:33:20] <XXCoder> it was 6 months old
[05:33:27] <_methods> yeah lathes can get ugly real fast
[05:33:37] <XXCoder> I'm scared of lathes frankly
[05:33:44] <XXCoder> I only ran lathe 5 times so far
[05:34:44] <XXCoder> anyway
[05:34:52] <XXCoder> lets see what happens tomorrow.
[05:34:54] <_methods> you should be scared of all of them
[05:35:05] <enleth> there was an yt video of a substantially sized lathe with the saddle ripped from the ways in a crash
[05:35:30] <_methods> yeah that's a good crash lol
[05:36:22] <enleth> the toolholder was missing completely, I guess whoever was recording that did not think of looking at the ceiling yet
[05:36:37] <enleth> I'd bet it was lodged there
[05:37:18] <archivist> throwing parts for yards on a crash
[05:38:05] <_methods> man i was setting up a new part on a lathe one time and it was about 6" diameter and about 8" long 304ss part
[05:38:08] <archivist> was a long walk to get a bit at a factory I used to work at :)
[05:38:29] <_methods> the guy who was on the machine before me had turned the chuck pressure way down because he was doing a thin wall part
[05:38:34] <_methods> and i didn't catch that
[05:38:41] <archivist> wrecked the saw blade
[05:38:53] <_methods> i spun that part up that it slung that blank out of the chuck
[05:39:10] <XXCoder> ouch
[05:39:10] <_methods> knocked all my tools off the turret and smashed the hell out of the inside of the lathe
[05:39:19] <_methods> i shit my pants
[05:39:38] <_methods> put a huge dent in the door
[05:39:48] <XXCoder> was it repaired or?
[05:40:04] <_methods> well luckily all it did was mess up all my tools and cosmetic damage to the door
[05:40:16] <_methods> the turret was still true thank god
[05:40:29] <_methods> so i just lost like 2 hours resetting tools
[05:40:53] <enleth> _methods: I'd label the dent on the door "this is why you check chuck pressure"
[05:41:00] <_methods> yeah
[05:41:18] <_methods> now whenever i set up a lathe it's the first thing i check lol
[05:41:35] <enleth> would do wonders to keep newbies alert
[05:42:05] <_methods> man it was horrible too because i was single blockin it since it was a new program
[05:42:11] <_methods> so my face was right up against the window
[05:42:24] <_methods> that first tool touched the blank and BOOOOOOOOOOOM
[05:42:28] <_methods> pants full of poo
[05:42:57] <malcom2073> Yowch, glad it didn't get you
[05:43:03] <malcom2073> parts coming loose is scary
[05:43:11] <_methods> it's why i always close the door too lol
[05:43:11] <XXCoder> yeah i would be whole pounds lighter after that
[05:43:22] <_methods> i've always been good about that
[05:43:22] <malcom2073> Guy at my work had a vacume hold down fail on a mill, took out half his face
[05:43:35] <_methods> yeah that's why i make sure door is close
[05:43:40] <malcom2073> Yeah, his door was closedheh
[05:43:41] <malcom2073> it went through it
[05:43:43] <_methods> saw i guy get knocked out runnin with door open
[05:43:47] <_methods> oh ouch
[05:43:56] <malcom2073> It was only 1/4" lexan
[05:44:07] <XXCoder> ouch
[05:44:17] <_methods> musta been a haas lol
[05:44:28] <malcom2073> It was some large VMC, the 20hp motor variety
[05:44:44] <_methods> cnc machines are dangerous that's for sure
[05:44:53] <enleth> malcom2073: started spinning on the drill and got loose at high rpm I guess?
[05:45:04] <XXCoder> _methods: yeah
[05:45:09] <malcom2073> enleth: that's what we assume happened yeah
[05:45:23] <XXCoder> malcom2073: at training job, we had "air blackouts"
[05:45:30] <XXCoder> guy was using vacuum hold
[05:45:47] <XXCoder> it sure flew good, but luckly he used portable wall to block
[05:47:30] <XXCoder> manual mill not cnc though
[05:47:43] <XXCoder> and they later upgraded from single big air tank to 4
[05:48:27] <enleth> are there any viable failsafe approaches for a vacuum table?
[05:49:11] <archivist> remove the vacuum table and use bolts
[05:49:17] <XXCoder> cant
[05:49:25] <XXCoder> its facemilling very thin part
[05:49:33] <XXCoder> and it covers entire thing in a shot
[05:50:26] <enleth> maybe glue it and dissolve/melt the glue later?
[05:50:51] <XXCoder> if I recall, strip of metal, 3 mm thick, mill off around half mm off both sides
[05:51:05] <XXCoder> enleth: could be a solution but not solution they used
[05:51:22] <enleth> the clickspring guy does that, seems to be effective and safe on big flat parts
[05:52:11] <_methods> yeah they make uv cure setups for stuff like that
[05:52:13] <enleth> the force needed to shear off the glue sideways is enormous
[05:52:19] <_methods> much safer than vacuum
[05:52:26] <_methods> more expensive though
[05:52:40] <XXCoder> do glue just melt off part too?
[05:52:50] <XXCoder> part required to be very smooth
[05:52:52] <_methods> the uv cures it and releases
[05:53:06] <_methods> you put uv lights in your fixture plate
[05:53:42] <_methods> https://www.youtube.com/watch?v=f5eSam7o8gk
[05:53:43] <_methods> like that
[05:54:15] <enleth> XXCoder: and if you want it cheaper, you glue the part to a ribbed plate with cyanoacrylate glue, then heat the plate to soften the glue
[05:55:41] <archivist> shellac as a hot melt glue too
[05:55:49] <XXCoder> cool. company work at now dont make that type parts though so its fine lol
[05:56:24] <_methods> oh snap
[05:56:46] <_methods> that freddy gray guy that died in baltimore had spine surgery the month before he died
[05:57:46] <_methods> guess that might make the prosecutions case a little tougher
[05:58:39] <XXCoder> why?
[05:58:54] <_methods> because he had a preexisting condition
[05:59:22] <XXCoder> it was a health insurance lawsuit or?
[05:59:38] <_methods> no
[05:59:59] <_methods> you remember there were like riots in baltimore a while ago
[06:00:25] <_methods> because the police "murdered" this guy freddie gray
[06:01:47] <XXCoder> from what i read, he got neck injury, and he didnt live because he didnt get any care
[06:03:47] <XXCoder> his neck was seriously broken so he couldnt breathe
[06:03:54] <XXCoder> so he suffered brain death
[06:05:17] <_methods> well like most stories, they're starting to find that there is more to it
[06:05:56] <XXCoder> earlier news just say back problems, while some other say he also has broken neck
[06:06:00] <_methods> or at least more of the truth is starting to leak out
[06:06:22] <XXCoder> being a cop does noit mean he or she is automically in right
[06:06:42] <XXCoder> theres no way to know what is truth so I'll leave em to figure it out,.
[07:14:26] <zeeshan> yawn :D
[07:15:30] <archivist> WAKE UP
[07:15:54] <MikkoP> Hello!
[07:16:10] <zeeshan> hehe
[07:16:11] <jthornton> how can you delete partitions on linux?
[07:16:24] <zeeshan> fdisk
[07:16:30] <MikkoP> jthornton: Or gparted
[07:18:00] <jthornton> gparted looks much easier
[07:18:22] <MikkoP> jthornton: Might be better if you aren't used to terminal tools :)
[07:18:31] <zeeshan> fdisk is easy!
[07:19:16] <archivist> fsking up is easy too
[07:19:21] <MikkoP> zeeshan: I prefer fdisk but it's a matter of opinion :)
[07:19:56] <jthornton> I'm used to the terminal
[07:21:01] <MikkoP> Hey, what about calculating maximum lifting weight for stepper motors? Wikipedia has something https://en.wikipedia.org/wiki/Ball_screw#Equations
[07:21:31] <jthornton> oh I remember now there are two hard drives in this computer lol
[07:22:21] <MikkoP> But with my 3 Nm motors and 5 mm pitch (assuming 90 % efficiency) it says almost 3400 Newtons...
[07:36:44] <enleth> MikkoP: 3Nm of what? holding torque?
[07:36:58] <MikkoP> enleth: yes
[07:37:24] <archivist> holding torque is not what they can move
[07:37:45] <MikkoP> archivist: No it's not but how do I calculate?
[07:37:49] <enleth> so assuming a ballscrew that can be backfed, you'd have to apply 3400N to force it to turn
[07:37:58] <jthornton> yea it is just how hard it will not move lol
[07:38:07] <archivist> if he got the maths right
[07:38:08] <enleth> sounds not completely unreasonable
[07:38:23] <enleth> but a little high
[07:38:37] <archivist> I am somewhat sceptical of that number
[07:39:44] <enleth> MikkoP: look for dynamic torque charts for your motor
[07:39:46] <MikkoP> archivist: http://www.wolframalpha.com/input/?i=3+%3D+%28x+*+0.005%29+%2F+%282+*+pi+*+0.90%29
[07:42:12] <archivist> put your numbers in http://www.daycounter.com/Calculators/Lead-Screw-Force-Torque-Calculator.phtml
[07:47:15] <jthornton> cool calculator
[07:48:31] <MikkoP> archivist: I tried this earlier today but didn't understand it. I assume force is the amount that needs to be lifted. Let's say it's 300 N or 30 kg. I have NEMA 23 motors so 0.25 inch shaft diameter (or should this be ball screw diameter?). I'm not sure about thread density. My ball screws have 5 mm pitch. Friction coefficient I set to 0.2 to be on the safer side.
[07:48:56] <MikkoP> This outputs 29.2 Ncm raising torque and lowering -9.7.
[07:50:38] <archivist> would be interesting to actually measure a screw one day
[07:52:54] <archivist> it basically depends on the helix angle which is a function of pitch and diameter
[07:56:13] <MikkoP> Someone should do "CNC for newbies" or something
[07:56:45] <MikkoP> According to the Wikipedia page on helix angle I get 87 degrees for my screw. What?!
[07:57:13] <MikkoP> 84*
[07:59:59] <archivist> seems about right
[08:00:04] <ReadError> https://www.anaheimautomation.com/products/brushless/brushless-motor-item.php?sID=148&pt=i&tID=96&cID=22
[08:00:11] <ReadError> found some really cheap BLDC motors
[08:00:31] <ReadError> the one in yellow is overstock sale
[08:01:22] <MikkoP> archivist: Yea I got no clue what to do with these :D
[08:25:35] <JT-Shop> ordered a co2 inflater and got a white wall 700x23c tire lol
[08:37:21] <ssi> morn
[09:21:12] <Sync> ReadError: low voltage stuff :/
[10:16:29] <Erant> Anyone have a good source for oldham couplings? I'm starting to second guess my choice of coupling.
[10:17:14] <Erant> (Currently using the cheapo Chinese aluminum ones, but they're basically a torsion spring. A stiff one, but a spring nonetheless)
[10:19:09] <cradek> mcmaster has a good selection: http://www.mcmaster.com/#oldham-couplings/=105ffpd
[10:20:23] <Erant> That's what I figured, just wondering if there was other places.
[10:23:50] <archivist> local to me http://www.arceurotrade.co.uk/Catalogue/Stepper-Motors/Oldham-Couplings
[10:31:23] <Erant> 'bout the same price. I'll just order 'm from McMaster. Hopefully get rid of the annoying ringing on my servo.
[10:32:20] <Erant> And I need to replace the nuts, and the gibs, and and and :)
[10:43:17] <CaptHindsight> Erant: McMaster has many in stock but they tend to be pricey. http://www.ruland.com/ps_couplings_oldham.asp#e-catalog is factory direct
[10:43:40] <CaptHindsight> ZORO and Amamzon also tend to have some in stock
[10:44:06] <Erant> Oh, sweet, thanks.
[10:44:30] <CaptHindsight> http://www.huco.com/distributors.asp
[10:44:48] <Jymmm> HF 20% off Dec 7-9 http://harborfreight.com/
[10:45:18] <CaptHindsight> i wonder if they sell toilet paper? ^^
[10:45:44] <Jymmm> CaptHindsight: That's free (flyers)
[10:47:24] <Erant> Jymmm: I have like 3 of those coupons.
[10:47:29] <Erant> I get them in the mail all the time.
[10:47:40] <Erant> I don't buy anything at HF without one these days. :P
[10:47:43] <Jymmm> not everyone does
[10:47:54] <Erant> Oh, I know, I appreciate it.
[10:48:29] <CaptHindsight> save money by buying elsewhere and something more reliable
[10:49:00] <Jymmm> It depends on what it is. They have tarps that aren't too bad,
[10:49:33] <Jymmm> cheaper than home depot
[10:53:47] <Jymmm> $10 8x11 silver tarp, good for covering woodpile, car, project, etc. http://www.harborfreight.com/8-ft-6-in-x-11-ft-4-in-silverheavy-duty-reflective-all-purposeweather-resistant-tarp-69201.html
[10:54:51] <_methods> great for cheap tools to put in convenient locations
[10:55:22] <_methods> i have allen wrenches strategically located throughout my neighborhood thanks to HF
[10:55:35] <_methods> and wrenches at every machine lol
[10:55:37] <Jymmm> neighborhood???
[10:55:42] <_methods> lol
[10:55:48] <_methods> i kid i kid
[10:55:59] <_methods> but i do have them all over the house
[10:56:07] <_methods> i never have to go looking for allen wrenches
[10:56:08] <Jymmm> I doubt it, you probably yape em under the mailboxes
[10:56:11] <Jymmm> tape*
[10:56:12] <archivist> when the break he throws with some velocity
[10:56:17] <archivist> the/they
[10:56:28] <Jymmm> archivist: ah
[10:58:18] <archivist> I have never quite understood the tantrum throwing of objects
[10:58:38] <Jymmm> bow saw for $7 http://www.harborfreight.com/21-bow-saw.html
[10:58:49] <Jymmm> It's actually not bad either.
[11:02:11] <Erant> CaptHindsight: Looks like Amazon is actually the cheapest, at about $20 a coupling.
[11:03:59] <CaptHindsight> the shipping might be much higher
[11:04:16] <Erant> Free shipping
[11:06:07] <Erant> The rated RPM is a little lower, 3000, but that still gives me 150IPM rapids, which my little machine is unlikely to get, so ;)
[11:08:14] <jdh> I have hf digital micrometers everywhere
[11:10:33] <_methods> i hate searching for wrenches and allen wrenches
[11:10:48] <_methods> so i just bought a bunch of sets and put them all over my garage and house lol
[11:12:36] <SpeedEvil> 'how the fuck can I lose 12 8mm allen keys'
[11:12:43] <_methods> hahahah
[11:12:53] <jdh> how many 7mm do you have?
[11:20:07] <Jymmm> How many 9mm that you can turn into 8mm do you have? lol
[11:21:30] <CaptHindsight> I bought a bunch of allen keys <1.5mm from McMaster last week. I was surprised by how few suppliers stock them
[11:23:44] <Jymmm> CaptHindsight: what take 1.5mm ?
[11:28:47] <lair82> pcw_home is it going to hurt to run that "sudo make clean" command to re-do that kernel, or should I not worry about and just start with "make xconfig" ?
[11:52:57] <enleth> lair82: make clean will not break anything and it's a good idea
[13:18:08] <maxcnc> hi all Still no winter in germany around sunny and nice day today Xmas sale is stuck
[13:35:45] <maxcnc> Hecke: ab durch die ;-)
[13:36:00] <Hecke> Hi Max
[13:36:22] <Hecke> Max: Ich bin überrascht, dass hier ja sogar deutsch gesprochen wird :)
[13:36:35] <maxcnc> viele deutsche hier
[13:36:53] <maxcnc> aber wird nicht gerne gesehen das ist ein eng chanell
[13:37:15] <ssi> dang germans
[13:37:33] <maxcnc> ssi so many germans here cand belive it myself
[13:37:40] <ssi> it's like an invasion
[13:38:13] <Hecke> ssi: These times are long ago :D
[13:39:23] <Hecke> i was just writing my request in english ;)
[13:39:42] <maxcnc> where are you in germany
[13:40:18] <Hecke> north rhein westfalia, its western germany and whats your location?
[13:41:09] <maxcnc> Zweibrücken
[13:52:43] <Deejay> Hecke, where exactly? :)
[13:53:28] <Deejay> ruhrgebiet?
[13:54:11] <Deejay> krauts overtake! ;)
[13:54:59] <Hecke> yes, ruhrgebiet :D
[13:55:12] <Deejay> bochum? :)
[13:55:51] * Deejay is also from NRW
[13:55:55] <Hecke> of course
[13:56:01] <Deejay> somewhat north of the ruhrgebiet
[13:56:12] <Hecke> ahh krauts invasion
[13:56:26] <Deejay> ^^
[14:04:54] <FAalbers> This is cool ... https://www.youtube.com/watch?v=laFdxYrPcvQ
[15:06:10] <CaptHindsight> FAalbers: there are several other slow motion cutting tool videos that you might also enjoy on the tubes
[15:07:11] <FAalbers> I'm sure
[15:07:20] <CaptHindsight> https://www.youtube.com/watch?v=mRuSYQ5Npek https://www.youtube.com/watch?v=qLJyN7dVcgA
[15:09:22] <CaptHindsight> super slow motion movie from gas metal arc welding https://www.youtube.com/watch?v=rB9n9Mt68J0
[15:11:55] <CaptHindsight> slo-mo MIG https://www.youtube.com/watch?v=MRIGks3gxG0
[15:19:02] <FAalbers> That is so cool CaptHindsight ! How the hell where they able to film the first one ?
[15:20:07] <CaptHindsight> FAalbers: there's a write up about it. The tool and material was up against a piece of glass
[15:20:54] <XXCoder> love how much it looks like clay.
[15:21:45] <ReadError> any creative solutions to adding encoders to single shaft motors?
[15:21:59] <ReadError> I snagged a few of the blowout BLDC servos
[15:23:50] <XXCoder> ReadError: between the motor and screw?
[15:24:01] <XXCoder> it'd have to use two couplers or something
[15:24:17] <ReadError> yea, was wondering if they had something to fit over the existing shaft
[15:24:23] <ReadError> like a coupler+enclosure
[15:24:24] <PetefromTn_> most people just drill and tap the end shaft in the lathe
[15:24:26] <ReadError> then mount that to something
[15:25:14] <XXCoder> some machines has rotating nut at other end, could use for encoder? but then backlash probably will affect it
[15:25:18] <ReadError> I think if I switch my project over to them ill just buy the double sided ones and proper encoders
[15:25:40] <ReadError> but for 29$ I just grabbed some to play with VESC
[15:27:20] <CaptHindsight> ReadError: what is the motor driving? A shaft with a coupling? Is there room on the other end of the shaft for an encoder?
[15:27:36] <ReadError> CaptHindsight well I want to use them on my PNP possibly
[15:27:46] <ReadError> which will need a pulley for a belt
[15:28:03] <ReadError> https://www.anaheimautomation.com/images/brushless/dimension/BLWR235S-36V-4000-03Dimensions(800x298).png
[15:28:08] <ReadError> these are too large for PNP though
[15:28:17] <XXCoder> wow CaptHindsight the arc weild one is weird
[15:29:14] <CaptHindsight> PNP? transistor? plug-n-play? Penelopes and Patricias?
[15:29:22] <XXCoder> P=NP?
[15:29:25] <ReadError> pick-n-place
[15:32:47] <CaptHindsight> http://openpnp.org/ whatever happened to this?
[15:34:04] <Tom_itx> it is under 'heavy' developement
[15:34:06] <ReadError> thats what im using ;)
[15:34:13] <ReadError> some bugs but otherwise working
[15:34:18] <XXCoder> checked forum
[15:34:22] <XXCoder> seems still current
[15:34:25] <XXCoder> if but slow
[15:34:30] <XXCoder> bit
[15:34:46] <ReadError> yea he got back from china a bit ago
[15:34:51] <ReadError> and has been getting back in to swing
[15:36:58] <ReadError> XXCoder I think the speed is mostly limited by mechanics people have used
[15:37:10] <ReadError> thats why I am thinking about going over to servos
[15:37:19] <ReadError> something with a light rotor
[15:37:20] <XXCoder> cool
[15:38:11] <CaptHindsight> http://openbuildspartstore.com/
[15:40:24] <CaptHindsight> I was considering making a similar site but HAAP.com was already taken
[15:40:40] <XXCoder> OPENHAAP
[15:41:06] <CaptHindsight> Open Half-Assed Automation Products
[15:41:11] <CaptHindsight> sounds good
[15:41:35] <XXCoder> AHAAP = awesome half-assed automation products
[15:42:05] <CaptHindsight> WAHAAP way awesome
[15:44:06] <CaptHindsight> http://openbuildspartstore.com/v-slot-nema-23-linear-actuator-bundle-lead-screw/ for a few extra $$ this could be far less wobbly
[15:44:07] <XXCoder> WOWHAAP wow overly wonderous half assed automation products
[15:44:52] <ReadError> im not using the openbuilds build though
[15:44:57] <ReadError> i got hiwin rails

[15:49:02] <Erant> I'm quite glad I didn't end up going with a router in the end.
[16:12:48] <andypugh> I won http://www.ebay.co.uk/itm/121823242788 on ebay. The vendor acidentally sent http://www.ebay.co.uk/itm/111832265508 instead.
[16:13:27] <cradek> oops
[16:13:48] <andypugh> Thats a 16Nm 2.9kW monster
[16:14:29] <andypugh> Looks great. Would make a nice lathe spindle drive, I bet. But isn’t morally mine, I feel.
[16:14:48] <XXCoder> yeah
[16:15:28] <CaptHindsight> did they send the winner of the other motor your motor?
[16:15:31] <PetefromTn_> I need to get rid of this servo that WAS on my CNC lathe now that I have all brand new ones here..
[16:15:34] <andypugh> Someone else is going to get a much smaller motor than they wanted
[16:16:04] <andypugh> This big boy has a 17-bit serial encoder, which I don’t really know how to use either.
[16:16:05] <XXCoder> andypugh: you better get money for shipping it back
[16:16:10] <XXCoder> HEAVY motor
[16:16:15] <andypugh> 19kg
[16:17:11] <CaptHindsight> there goes that perfect feedback rating
[16:17:30] <XXCoder> CaptHindsight: actually guy can recover by paying people to ship back
[16:17:37] <XXCoder> and ship em to correct people
[16:17:51] <XXCoder> its how he or she handles problem that will dermine the feedback
[16:18:10] <CaptHindsight> maybe, but some people post feedback first and don't bother trying to work it out
[16:18:28] <XXCoder> yeah
[16:23:29] <Valen> my philosophy is anybody can fuck up, its how you deal with it that matters
[16:24:37] <CaptHindsight> 450 horsepower at 8,000 rpm polymer engine http://www.enginelabs.com/news/plastic-race-engine-returns-as-polimotor-2-project-underway/
[16:28:33] <andypugh> An engine with some unstressed parts made of polymers....
[16:29:54] <CaptHindsight> andypugh: rods and pistons were metal, do you know what else?
[16:30:07] <CaptHindsight> crank, valve springs etc?
[16:30:22] <andypugh> According to the article, cylinders heads and camshafts
[16:30:31] <andypugh> Ford Pinto crank
[16:30:36] <Erant> Anything exposed to severe heat, basically?
[16:30:51] <Erant> Or pressure
[16:36:48] <SpeedEvil> Aluminium space-frame would presumably be lots better
[17:06:50] <Erant> Dumb question, could I machine M2 tool steel on a mill with like a grinding tool?
[17:08:39] <Deejay> gn8
[17:11:16] <SpeedEvil> Or carbide?
[17:11:44] <JT-Shop> use carbide tooling for hard metals
[17:12:00] <JT-Shop> grinding and mill don't go together well
[17:14:04] <SpeedEvil> Also - do you mean annealed, or hardened?
[17:15:06] <Erant> Basically, I'm trying to figure out whether or not I can make tools for a lathe on my mill
[17:16:23] <SpeedEvil> yes
[17:16:33] <SpeedEvil> To cut what is the question
[17:16:42] <SpeedEvil> aluminium and brass is trivial
[17:17:07] <SpeedEvil> https://www.youtube.com/watch?v=jlNxvnOxMCE
[17:17:58] <Erant> That's largely what I'd be aiming for.
[17:19:35] <JT-Shop> I mill up to about RC58 on my mill with carbide tooling
[17:20:03] <SpeedEvil> Ah
[17:20:14] <JT-Shop> if you take the right amount of chip out the material never even gets warm with no coolant
[17:20:14] <SpeedEvil> You can indeed harden HSS - but holy shit
[17:20:24] <JT-Shop> coolant = bad for carbide
[17:20:31] <SpeedEvil> '
[17:20:31] <SpeedEvil> Pre heat the steel in two steps; 450-500°C then 850-900°C. Then continue heating to the final hardening temperature of 1200-1250°C and ensure that the component is heated through. Care must be taken not to allow the component to remain too long at the hardening temperature. Quench in warm oil or brine. If quenching in brine allow the tools to equalize, then complete the quench in air. If quenching in oil remove the component from the oil at
[17:20:31] <SpeedEvil> about 500°C and then air cool. M2 high speed steel is also suitable for vacuum hardening.
[17:20:38] <SpeedEvil> Hawt
[17:22:51] <andypugh> You can go old-school and use something like O1 tool steel. Easy to harden, worked perfectly well for centuries.
[17:23:08] <SpeedEvil> yeah
[17:23:21] <Erant> SpeedEvil: That's a great video.
[17:23:31] <SpeedEvil> It is.
[17:23:38] <SpeedEvil> Plus he uses comparatively modest tooling.
[17:23:40] <SpeedEvil> Which is nice
[17:23:52] * SpeedEvil sighs.
[17:23:53] <SpeedEvil> http://www.westyorkssteel.com/
[17:24:01] <SpeedEvil> 'uk delivery only 25 pounds'
[17:24:05] <Erant> Totally. That's given me the confidence that I could totally do this at home with what I have.
[17:24:27] <SpeedEvil> What the hell is teh point of advertising that, if you're going to stick up a whole website, and 'call' for every single item.
[17:24:31] <Erant> Really time to get that lathe. :P
[17:25:10] <andypugh> SpeedEvil: You can buy silver steel (a lot like O1) easily. From Cromwell tools for a start, and on a saturday morning.
[17:25:50] <SpeedEvil> At exactly the other end of the country from me.
[17:26:15] <andypugh> Eh? They have branches nationwide
[17:26:25] <SpeedEvil> Oh - google lied and said two branches
[17:27:05] <andypugh> Many ebay vendors of silver steel and O1 too
[17:27:25] <SpeedEvil> Oh - right - that's more reasonable
[17:27:26] <SpeedEvil> yes.
[17:28:53] <andypugh> I tend to call in to buy stuff, but they are les than half a mile from my house.
[17:34:54] <CaptHindsight> metalsupermarkets.com lets you roder online but if you call any dealer your price will be 40% lower
[17:35:01] <CaptHindsight> roder/order
[18:00:51] <thesaint> hi, anybody out there?
[18:02:52] <JT-Shop> nope
[18:04:17] <thesaint> hi, i am trying to learn linuxcnc gcode for lathe. do you know where i can find a good resource? scripts of basic operations maybe? thanks..
[18:04:34] <Tom_itx> gcode is pretty much gcode
[18:05:23] <Tom_itx> http://www.enginelabs.com/news/plastic-race-engine-returns-as-polimotor-2-project-underway/
[18:05:27] <Tom_itx> woops
[18:05:43] <Tom_itx> http://linuxcnc.org/docs/2.7/html/gcode/g-code.html
[18:06:24] <Tom_itx> http://www.cnccookbook.com/CCCNCGCodeRefTurn.html
[18:07:23] <thesaint> Tom - do you have a cnc lathe?
[18:07:31] <Tom_itx> then there's always this one: http://gnipsel.com/linuxcnc/g-code/
[18:07:44] <thesaint> gnipsel is the best i found so far..
[18:07:49] <Tom_itx> nope but i've programmed / run one
[18:08:01] <Tom_itx> yeah he's quite a character i hear
[18:08:08] <thesaint> well those links apart from gnipsel are not usefull.
[18:08:43] <thesaint> i am really looking for scripts i can play with to get an idea what is going on.
[18:08:45] <Tom_itx> the author is hiding here somewhere
[18:09:00] <thesaint> his was good.
[18:09:27] <thesaint> and i will work from there if that is all i can find.
[18:10:00] <thesaint> would be good if i could chat with someone with a cnc lathe and find out how they actually use it to make parts...
[18:11:01] <Tom_itx> just ask, there are plenty here
[18:12:07] <thesaint> does anyone have a script i can have a look at that turns a rod to a certain diameter and length?
[18:12:37] <thesaint> what is the workflow for making parts with a cnc lathe?
[18:13:00] <thesaint> are there any helper scripts for doing this stuff?
[18:13:08] <thesaint> do i have to make them all myself?
[18:14:01] <JT-Shop> thesaint: http://gnipsel.com/shop/hardinge/hardinge.xhtml
[18:14:30] <JT-Shop> makes me happy to read that thesaint
[18:15:01] <JT-Shop> ngcgui handles 95% of the ops on my CHNC lathe
[18:15:29] <JT-Shop> btw, I'm gnipsel
[18:15:36] <thesaint> jt-shop - you are gnipsel?
[18:15:44] <JT-Shop> aye
[18:16:03] <thesaint> cool, have been looking at your scripts and learning - thanks!
[18:16:08] <JT-Shop> I'm also jthornton
[18:16:36] <JT-Shop> your welcome, glad someone gets a benefit from them
[18:17:23] <thesaint> how do i setup the ngcgui ? that is what i am looking for to get started. yes i did benefit, only crashed my machine twice :-)
[18:17:32] <JT-Shop> Tom_itx: 12 pieces of siding and 6 pieces of gable to go
[18:17:38] <thesaint> just small crashes.. lol
[18:17:57] <Tom_itx> you might make it by winter
[18:18:08] <JT-Shop> http://linuxcnc.org/docs/2.7/html/gui/ngcgui.html
[18:18:29] <JT-Shop> lol it is winter but I was working in a tee shirt most of the day
[18:18:49] <Tom_itx> yeah it turned out pretty nice today
[18:18:57] <Tom_itx> it was rather chilly at 3am though
[18:19:09] <jdh> I went biking in shorts/short sleeve jersey
[18:19:16] <Tom_itx> had to make an airport run... been a long day
[18:19:18] <JT-Shop> going to be in the 60's for the next few day
[18:19:19] <JT-Shop> s
[18:19:38] <JT-Shop> I've still not rode the new to me road bike
[18:19:52] <jdh> just like teh previous owner?
[18:20:04] <JT-Shop> not really, I have a pump lol
[18:20:27] <JT-Shop> got the water bottle things put on yesterday, computer should be here by Friday
[18:20:32] <thesaint> jt-shop - looks good... thanks! more to play with.
[18:20:53] <JT-Shop> I'll pinch the co2 filler from my mountain bike till the other one comes in
[18:21:35] <JT-Shop> been busy trying to get the siding up on the garage and shop
[18:21:42] <Tom_itx> computer!!
[18:21:45] <JT-Shop> on a mission you know
[18:22:12] <jdh> a mission, from god?
[18:22:25] <JT-Shop> not really...
[18:22:39] <JT-Shop> http://www.amazon.com/gp/product/B013SD1X9W?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00

[18:23:05] <JT-Shop> got a tire lol
[18:23:21] * thesaint right, off to play with JT-Shop OD turning subroutine....
[18:23:30] <JT-Shop> have fun
[18:23:31] <Tom_itx> i got one of those once when making an anemometer
[18:23:42] <JT-Shop> a tire?
[18:23:49] <Tom_itx> a bike puter
[18:24:48] <JT-Shop> the tire they sent lol http://www.amazon.com/Michelin-Dynamic-Classic-Tire-Black/dp/B00IFC1CT8/ref=sr_1_33?ie=UTF8&qid=1449619206&sr=8-33&keywords=700x25c
[18:24:49] <thesaint> thanks!
[18:25:03] <jdh> the co2 comes from backcountry. You can get 12% cashback if you click through activejunkie.com to backcountry
[18:25:59] * JT-Shop wonders where the wife is...
[18:26:12] * Tom_itx as well
[18:26:23] <Tom_itx> mine not yours
[18:26:49] <CaptHindsight> https://github.com/xboxhacker/OpenFeeder "WARNING: This is my very first ever 3D Cad design." yet also states "Most likely over engineered!"
[18:26:54] <JT-Shop> oh I see a text she is just leaving work
[18:27:11] <JT-Shop> understand
[18:27:53] * JT-Shop twists his hat around and goes to start the jambalaya
[18:28:04] <JT-Shop> say goodnight Gracie
[18:34:10] <Tom_itx> CaptHindsight what was that contraption?
[18:34:45] <CaptHindsight> Tom_itx: tape feeder for an open pick-n-place
[18:34:54] <Tom_itx> ahh
[18:35:04] <Tom_itx> i saw the feed teeth
[18:38:46] <CaptHindsight> https://github.com/xboxhacker/OpenFeeder/blob/master/PHOTOS/exploded_view.jpg
[18:44:46] <thesaint|2> JT-Shop - quick question - 'file ended with no percent sign... - OD.ngc, for some reason the script will not load in linuxcnc without that error message, any idea?
[18:45:35] <jdh> you need a postamble with a % or m2 in it
[18:46:46] <thesaint|2> a postamble?
[18:47:28] <thesaint|2> jdh - so simply have a line with m2 as the end of the script?
[18:47:36] <jdh> yes, or %
[18:47:44] <thesaint|2> thanks!
[18:52:49] <t12> sweet
[18:52:54] <t12> i just scored a varian IGP
[19:12:46] <PetefromTn_> Awesome!!.....er WTF is that?
[19:19:09] <CaptHindsight> type pf vacuum pump
[19:20:49] <andypugh> thesaint|2: I have a set of scripts that I use for nearly everything. Demo video here. No G-code is needed: https://www.youtube.com/watch?v=nIYMfyf4jDI
[19:23:13] <thesaint|2> andypugh - thanks, i will take a look!
[19:24:34] <thesaint|2> custom gladeVCP gui - how do i set that up? are there instructions anywhere? thanks..
[19:26:26] <andypugh> You can download the whole thing from: https://forum.linuxcnc.org/forum/41-guis/26550-lathe-macros?limitstart=0
[19:27:12] <thesaint|2> looks good..
[19:27:54] <thesaint|2> i just restored an emco pcturn55, took a while but all working. Now I learn to use linuxcnc...
[19:28:26] <andypugh> For more than one or two parts then something that generates a G-code program like ngcgui probably wins, but for “thinking in metal” which I do a fair bit of, I like my macros.
[19:30:04] <thesaint|2> yes, I would like to learn but i need to start somewhere. I would also like to make some parts now..
[19:30:45] <andypugh> My macros work like a sort-of souped-up power feed. So should get you going pretty quickly.
[19:31:38] <thesaint|2> where do i download the latest versions? is it the zip on the first page of the thread?
[19:31:53] <andypugh> Yes, I keep updating the zip in the first post
[19:36:45] <thesaint|2> okay, got the files, had a quick look. How do I set this up? Do I simply copy the files somewhere into my linux cnc install and modify some ini files? thanks.. - the readme did not detail - sorry for all the questions.
[19:39:19] <andypugh> Copy all the G-code files and PNGs into the same folder as your iNI file, then add the gladevcp line to the INI.
[19:39:21] <andypugh> I think
[19:39:26] <andypugh> It’s been a while
[19:40:39] <thesaint|2> do i need to install glade also? (is this part of linuxcnc already?) thanks..
[19:40:54] <andypugh> You should already have Glade.
[19:40:57] <thesaint|2> ok and then when i start up linuxcnc next it will be as shown?
[19:41:01] <andypugh> (You will find out, I guess)
[19:41:06] <andypugh> Should be
[19:41:27] <thesaint|2> with the extra 'cycles' tab...
[19:41:33] <andypugh> Yes
[19:42:04] <thesaint|2> cool..
[19:43:18] <thesaint|2> got it.. will try that tomorrow. many thanks! looks great...
[19:43:52] <thesaint|2> off to bed, late here and tired...
[19:44:24] <thesaint|2> thanks for the help! goodnight..
[19:44:46] <FAalbers> nite ... I'ma going home. Still at work
[19:45:43] <andypugh> Where is “here”?
[19:46:06] <andypugh> {‘cos it’s late here too, so may be the same “here”)
[19:46:17] <andypugh> Ah, I see, .de
[20:24:08] <cncnoob> Hey! I have a brideport interact 1 that has had the TCN-151 controller removed. I only have single phased 220v power, can I hook this machine to single phased power just to test the servo's and amps? (Spindle motor is disconected) My amps are single phased as well
[20:24:39] <andypugh> Tr it. Too-low voltage will either work or not.
[20:25:15] <PetefromTn_> I run a similar machine entirely on 230v single phase LOL
[20:25:27] <cncnoob> Thanks Andy! I'll try it out!
[20:25:37] <cncnoob> Anythign I should be aware of?
[20:25:57] <andypugh> I don’t really know, I don’t know much about the details of that machine.
[20:26:00] <cncnoob> possible damage or letting out any magic smoke? *cant put it back in:)*
[20:26:20] <andypugh> If they are velocity servos then they are likely to drift. Possibly quickly.
[20:27:22] <cncnoob> ok ill be on the look out. With the controller removed Ill just try a 1.5v battery for command voltage...
[20:28:04] <andypugh> You might have to set some enable lines.
[20:28:52] <cncnoob> hmm.. Ok ill read the schematic and see what it requries for an enable signal
[20:30:23] <cncnoob> Thanks, this channel rocks!
[20:33:01] <andypugh> Time for me to log off. For some reason the guys at work expect me to be awake.
[20:41:54] <cncnoob> PeteFromTN, where are you at in TN?
[20:42:03] <cncnoob> What mill do you use?
[20:44:32] <PetefromTn_> Oh I thought you did not hear me ;)
[20:44:42] <PetefromTn_> I am in the Knoxvegas area
[20:44:50] <PetefromTn_> and I have a cincinatti Arrow 500 VMC
[20:49:04] <CaptHindsight> cncnoob: are the servo amps powered by 2-pole or 3-phase?
[20:49:31] <CaptHindsight> soory you already said they are single phase
[20:49:46] <cncnoob> Im in Madison AL area, I picked this mill up in Savannah TN
[20:50:04] <cncnoob> Wish I had a VMC!
[20:50:34] <PetefromTn_> oh you have an interact knee mill I thought you had the small interact VMC
[20:51:15] <cncnoob> CaptHindsight Yes they are single phased. Just trying to make sure I dont burn it up :)
[20:52:04] <cncnoob> no just a small knee mill compared to the VMC's. Im a hobbyist~!
[20:52:36] <cncnoob> Pete, thatll be the next one.. Just have to convience the wife of that1
[20:52:44] <PetefromTn_> I hear ya LOL
[20:53:09] <cncnoob> how do you like your VMC?
[20:53:33] <PetefromTn_> Oh it's very nice. Would be even nicer If I ever finished the toolchanger LOL
[20:54:00] <PetefromTn_> but yeah it makes some very pretty parts for me daily. It has paid for itself several times over by now
[20:54:02] <cncnoob> Ok, so lets trade :) Ill fix the tool changer!
[20:54:17] <PetefromTn_> Ok what do you want to trade ;)
[20:54:51] <cncnoob> I want a small vmc but everything I found was so worn out and approx 8-10k range that I was afriad of trying to do a retrofit..
[20:55:33] <cncnoob> You can have my wife! haah then she cant say no! that'll learn her! lol
[20:56:00] <PetefromTn_> my machine is a linear guideway machine and has no hydraulics... everything is either electronic or pneumatic
[20:56:17] <PetefromTn_> I already have a wife and she probably does not want to share LOL sorry
[20:56:44] <cncnoob> I hear that linear was the way to go, makes a tight machine, has that been your experience?
[20:56:57] <cncnoob> lol
[20:57:17] <PetefromTn_> well linear is just less capable of taking really heavy cuts generally speaking
[20:57:41] <PetefromTn_> but the good part is if you do have a problem you can replace the guideways but it is not cheap really
[20:58:06] <PetefromTn_> I have had it for a year or two now and have made a lot of parts on it. SO far so good!
[20:58:31] <cncnoob> nice! Did you buy it for a retro? Or did it go out on you first?
[20:58:51] <PetefromTn_> well
[20:58:57] <PetefromTn_> I bought it partially working
[20:59:02] <cncnoob> *popcorn
[20:59:10] <PetefromTn_> and spent some considerable money fixing it
[20:59:15] <PetefromTn_> then it broke again
[20:59:27] <PetefromTn_> spent some considerable more money fixing it...AGAIN
[20:59:34] <PetefromTn_> then it broke AGAIN.
[20:59:38] <PetefromTn_> so I said screw it
[20:59:46] <PetefromTn_> and gutted it like a freakin' pig
[21:00:25] <cncnoob> did you go with the 5i25 7i77 combo? or did you use another soluition?
[21:00:28] <PetefromTn_> I replaced basically everything electronically speaking except for the coolant pump and spindle motor
[21:00:48] <PetefromTn_> Yeah I used the 5i25/7i77 and Teco servos and drives from Machmotion
[21:00:58] <PetefromTn_> I used a Hitachi VFD for the spindle drive
[21:01:16] <cncnoob> what size spindle motor does that have on it?
[21:01:27] <PetefromTn_> 10hp
[21:01:41] <cncnoob> thats must have been a large vfd
[21:01:45] <PetefromTn_> its kind of a strange motor
[21:02:06] <PetefromTn_> it actually spins 12k RPM and the spindle is geared down 2-1 so the max RPM is 6000 RPM
[21:02:18] <PetefromTn_> Its a 15hp VFD...
[21:02:40] <cncnoob> Thats a lot of torq
[21:03:17] <PetefromTn_> yeah it gets it done :D
[21:03:21] <cncnoob> If you had to do it over again, would you do it the same way?
[21:03:44] <PetefromTn_> well yeah I am right now working on a CNC lathe using the same basic setup
[21:04:43] <cncnoob> That would be awesome. Could make anything real quick like!
[21:05:43] <cncnoob> im thinking about the 5i25 / 7i77 setup in this knee mill. Something for now, then maybe get a vmc later after I build the shop. Im in the garage as of now.
[21:05:51] <PetefromTn_> its pretty decent. I have worked in a couple pro machine shops and feel like I could do basically anything they can to the same accuracy they can here in my own shop now. Can't wait for the CNC lathe to be done.
[21:06:06] <PetefromTn_> heh I am in the garage too
[21:06:10] <cncnoob> how far along are you?
[21:06:25] <cncnoob> What size lathe are you setting up?
[21:06:30] <PetefromTn_> well I just bought MOST of the electronics this month
[21:06:50] <cncnoob> i hear mesa is way behind in orders
[21:07:11] <PetefromTn_> This lathe is a Standard Modern CNC lathe, it is a flatbed lathe with about 14.5x40
[21:07:56] <cncnoob> thats enough to do anything I could think of.. too bad you dont want to trade me :)
[21:08:26] <cncnoob> I assume you are wanting to go servo's?
[21:08:29] <PetefromTn_> that is pretty much how I feel about it
[21:08:44] <PetefromTn_> yeah I bought brand new DMM servos and drives
[21:08:52] <PetefromTn_> 750watt AC
[21:08:56] <cncnoob> that hurt the wallet
[21:09:02] <PetefromTn_> yeah
[21:09:07] <PetefromTn_> about a grand for both axes
[21:10:01] <cncnoob> well im going to jump off of here! Talk to you later! take care
[21:10:12] <PetefromTn_> good luck man
[21:10:37] <cncnoob> you too! bye
[22:40:04] <zeeshan> zzZzzz
