[00:02:25] <_methods> if you're asking if an ssd drive will be more reliable than a spinning platter type disk drive i would have to say yes
[00:02:47] <Nick001-shop> OK - wondering whitch will last the longest
[00:03:09] -!- i_tarzan has quit [Read error: Connection reset by peer]
[00:03:09] <_methods> i would stick to the intel ssd's if you're concerned with reliability
[00:03:15] <Nick001-shop> What size is generally used?
[00:03:37] <_methods> personally for a linuxcnc box i think 128gb would be good
[00:03:42] <_methods> that's what i have in mine
[00:03:51] <Nick001-shop> I was looking at kingston

[00:04:04] <_methods> that is up to you
[00:04:04] <Nick001-shop> from newegg
[00:04:27] <_methods> i personally have never purchased a kingston ssd
[00:04:39] <_methods> i have crucial, intel and some other one

[00:04:47] <_methods> adata
[00:05:04] <_methods> the crucial 64gb drives are the only ones that have gone bad on me
[00:05:21] <_methods> all my other ssd's are still in service
[00:05:32] <Nick001-shop> I;ll stay away from that one
[00:05:54] -!- patricka_ has quit [Remote host closed the connection]
[00:05:57] <_methods> well i have purchased several larger crucials since then that are running fine
[00:06:08] <Nick001-shop> do they use the same connector as the 3-1/2" drives?
[00:06:17] <_methods> all mine have been sata
[00:06:30] <zeeshan> HSD: probotix sux\!! :P
[00:06:40] <Nick001-shop> 3-1/2 sata drive
[00:06:51] <_methods> yes
[00:07:20] <_methods> oh i also have samsung 1tb ssd
[00:07:35] <_methods> that's the last one i bought and so far it is working well
[00:07:58] <_methods> but i've only had it for about 5 months or so

[00:11:45] <Tom_itx> i got one but didn't plan to use it for anything but testing
[00:11:56] <Tom_itx> _methods good luck :)

[00:13:25] <Tom_itx> better ask for a rma now...
[00:14:05] <_methods> hmm i might do that i've only had it for awhile
[00:14:16] <Tom_itx> PCW wonder if that would run your eth boards
[00:14:36] <_methods> got it in october

[00:15:50] <Rab> zeeshan, what are these pix?
[00:16:40] <_methods> alright so don't buy a samsung 840 evo
[00:16:46] <zeeshan> rab what do you mean
[00:17:15] <Rab> zeeshan, what are they depicting?

[00:17:43] <Rab> Looks like a tool impact in a piece of metal under magnification?
[00:18:23] <zeeshan> im using a pyramidal indenter
[00:18:26] <zeeshan> was testing
[00:18:30] <zeeshan> if it measures the correct depth
[00:18:34] <zeeshan> using the 3d measurement system
[00:20:14] <Tom_itx> the great pyramids of egypt!
[00:20:26] <zeeshan> lol
[00:20:38] <zeeshan> its within +/-1 micron
[00:20:40] <zeeshan> its crazy
[00:20:41] <zeeshan> for depth measurement
[00:24:29] <zeeshan> HSD: i use the same card on my lathe
[00:24:37] <zeeshan> its been doing an okay job
[00:24:48] <zeeshan> i just hate how it doesnt have a pin output for 5v
[00:24:56] <zeeshan> you have to use those silly header pins
[00:25:00] <zeeshan> to get 5v

[00:52:48] <zeeshan> anyone run a lathe here a lot?
[00:52:56] <zeeshan> i mean a LOT!! :P
[00:55:52] <MacGalempsy> zeeshan: how goes it today?
[00:55:59] <zeeshan> being lazy :)
[00:56:06] <zeeshan> trying to figure out my lathe ploughing issue
[00:56:40] <MacGalempsy> we just had another client drop...i might end up as a miner yet...
[00:56:56] <zeeshan> crap :/
[00:57:14] <_methods> ploughing?
[00:57:21] <zeeshan> _methods yes
[00:57:28] <zeeshan> ignore the chanter in my video

[00:57:48] <zeeshan> most important thing to notice is
[00:57:50] <zeeshan> surface finish
[00:57:54] <zeeshan> and the raised burr
[00:57:57] <zeeshan> w/ both my tools
[00:58:13] <zeeshan> archivist told me its likely a dull edge

[00:58:19] <zeeshan> but its kinda weird that both m y tools are dull?
[00:58:32] <MacGalempsy> take smaller cuts? :\
[00:58:53] <zeeshan> i tried
[00:58:54] <zeeshan> didnt help
[00:58:55] -!- sumpfralle has quit [Ping timeout: 256 seconds]
[00:58:59] <zeeshan> tried 20 thou
[00:59:01] <zeeshan> 100 thou
[00:59:04] <zeeshan> 50 thou and 5 thou
[00:59:07] <zeeshan> does the same bs
[00:59:22] <MacGalempsy> what are you cutting?
[00:59:28] <zeeshan> cuts aluminum beautifully.. but thats really not a fair test
[00:59:34] <zeeshan> i tried cutting 1045, 1018
[00:59:37] <zeeshan> a36 hr
[00:59:39] <CaptHindsight> PCW: still need something for the GUI :(
[00:59:41] <zeeshan> not 1018 i mean
[00:59:46] <zeeshan> and stainless 304

[01:01:00] <_methods> well when you're running the cnmg you're not breaking at chip at all
[01:01:12] -!- FinboySlick [FinboySlick!~shark@squal.net] has joined #linuxcnc
[01:01:14] <_methods> so something is wrong with your feeds and speeds
[01:01:16] <zeeshan> i tried feeding
[01:01:17] <zeeshan> faster
[01:01:19] <zeeshan> it broke the chip
[01:01:24] <zeeshan> but still did that burr thing
[01:01:34] <zeeshan> i tried 300 sfm , 500 sfm
[01:01:44] <_methods> well you're definitely not taking enough DOC with the cnmg
[01:01:50] <zeeshan> its ccmt
[01:01:57] <zeeshan> did i say cnmg in the video?
[01:02:00] <zeeshan> i made a mistake if i did
[01:02:07] <zeeshan> the first one is vnmg
[01:02:10] -!- Albright has quit [Quit: Albright]
[01:02:13] <_methods> ah nah it just looked like cnmg i don't have volume on
[01:02:14] <zeeshan> and its making tiny chips

[01:02:18] <zeeshan> ah
[01:02:21] <zeeshan> its vnmg vs ccmt
[01:02:27] <zeeshan> .020 doc, 4.8 ipm feed
[01:02:32] <zeeshan> 500 sfm
[01:02:41] <_methods> yeah what's your tip radius
[01:03:04] -!- tjb1 has quit [Quit: Leaving]
[01:03:12] <zeeshan> vnmg is .015"
[01:03:31] <zeeshan> and ccmt is also the same
[01:03:33] <_methods> well i'd try to take at least .03 cuts
[01:03:44] <zeeshan> i did , i tried 50 thou 100 thou
[01:03:44] <_methods> but you said you tried takin real cuts
[01:03:47] <_methods> and same problem
[01:03:50] <zeeshan> yea man
[01:03:52] <zeeshan> its confusing me as hell
[01:03:59] <_methods> then you have some play somewhere
[01:04:03] <_methods> in the toolpost
[01:04:05] <_methods> or something
[01:04:13] <zeeshan> like the only thing i can think of...
[01:04:18] <zeeshan> is maybe play in the axial direction ?
[01:04:23] <_methods> could be
[01:04:24] <zeeshan> which would stop the tool from feeding?
[01:04:27] <zeeshan> like its like it's feeding
[01:04:29] <zeeshan> then not feeding
[01:04:30] -!- tjb1 [tjb1!~tjb1@cpe-69-207-197-216.stny.res.rr.com] has joined #linuxcnc
[01:04:31] <zeeshan> and then feeding again
[01:04:36] <zeeshan> so it goes from ploughing, cutting plughing
[01:04:42] <zeeshan> you can even hear it,
[01:04:48] <zeeshan> it goes nice cutting sound, then a "bump"
[01:04:52] <zeeshan> then nice cutting sound and another bump
[01:05:02] <_methods> yeah that's lash probably somewhere in there
[01:05:09] <_methods> in the x axis or the toolpost
[01:05:12] <_methods> or toolholder
[01:05:19] <zeeshan> x axis has no lash i measured th at
[01:05:26] <zeeshan> like .0003 lash
[01:05:32] <zeeshan> but x axis has 2.5 thou
[01:05:39] <_methods> have you put an indicator on the toolpost
[01:05:45] <zeeshan> the tool holder, i dont get why it all the sudden started moving
[01:05:48] <_methods> to see if it's moving excessively while cutting
[01:05:49] <zeeshan> can you tell me how?
[01:05:53] <zeeshan> i dont know how to set it up
[01:06:00] <zeeshan> to measure that it's deflecting under a cut
[01:06:00] <Cromaglious> looks like a gib to me...
[01:06:09] <_methods> possibly a big
[01:06:10] <_methods> gib
[01:06:14] <zeeshan> the cross slide gib?
[01:06:22] <Cromaglious> apron gid and compound gibs adjusted?
[01:06:32] <zeeshan> there is no apron gib
[01:06:38] <zeeshan> compound gib is locked
[01:06:42] <Cromaglious> err yeah cross slide not apron
[01:06:44] <zeeshan> cause i never move it
[01:06:51] <zeeshan> cross slide gib ill need to check
[01:07:02] <zeeshan> but is there a way to measure the deflection under a cut?
[01:07:06] <zeeshan> how would you setup your indicator to do that
[01:07:12] <zeeshan> mount it on the slide
[01:07:19] <zeeshan> plunge it onto the tool holder right at th ebeginning of the cut
[01:07:22] <zeeshan> and then take a cut?
[01:07:29] <zeeshan> and watch for any reversals?
[01:07:35] <_methods> what did you use for feed calculations?
[01:07:36] <Cromaglious> one way
[01:07:47] <zeeshan> _methods the insert details
[01:07:50] <Cromaglious> I'd mount it on the apron though
[01:07:53] <zeeshan> says 0.004-.008 ipr
[01:07:53] <_methods> your feed rate looks very slow
[01:07:55] <zeeshan> i used .006
[01:08:03] -!- tjb1 has quit [Client Quit]
[01:08:04] <_methods> k
[01:08:08] <_methods> well you should be good then
[01:08:27] <_methods> what sfm
[01:08:28] -!- tjb1 [tjb1!~tjb1@cpe-69-207-197-216.stny.res.rr.com] has joined #linuxcnc
[01:08:47] <zeeshan> i think i was at 500 sfm in that video
[01:08:52] <_methods> k
[01:08:56] <_methods> that sounds good
[01:09:06] <_methods> just wanted to rule that out
[01:09:14] <zeeshan> you know another symtom?
[01:09:20] <zeeshan> the work piece is HOT as hell to touch
[01:09:25] <_methods> i would say from what you're saying there is slop somewher
[01:09:25] <zeeshan> so i know its ploughing
[01:09:30] <zeeshan> rather than cutting
[01:09:50] <_methods> how does the insert tip look?
[01:09:59] <zeeshan> honestly its hard to tell by eye
[01:10:00] <_methods> looked like you had built up edge on there
[01:10:11] <_methods> run your fingernail across it
[01:10:16] <_methods> if it's smooth you're good to go
[01:10:17] <zeeshan> well what im gonna do in a bit is put a fresh insert
[01:10:21] <_methods> if not you have a problem
[01:10:21] <zeeshan> but i'd like to measure things while im doing it
[01:10:27] <zeeshan> okay
[01:10:49] <zeeshan> i just dont know exactly what the best way to measure deflection in a dynamic situation
[01:11:03] <zeeshan> without an accelrometer :P
[01:11:20] <_methods> well i just would put an indicator on the apron and against the toolpost to see if i can see any major fluctuations
[01:11:31] <_methods> it's going to be tough to get a "good" reading
[01:11:38] <_methods> but you're trying to find sore thumbs
[01:11:41] <zeeshan> it would reverse right?
[01:11:51] <_methods> it could go both ways
[01:11:59] <_methods> as it deflects back then bites in
[01:12:05] <zeeshan> yes
[01:12:11] <zeeshan> thats EXACTLY what it feels like
[01:12:13] <zeeshan> its deflecting
[01:12:19] <zeeshan> builds up load till it can finally cut
[01:12:22] <zeeshan> and then repeats
[01:12:24] <_methods> yeah
[01:12:44] <_methods> that is usually something you see in smaller lathes
[01:13:00] <_methods> they have a hard time pushing carbide enough
[01:13:01] <zeeshan> dude you dont understand
[01:13:11] <zeeshan> i want to buy a horizontal bed lathe so badly
[01:13:19] <zeeshan> but none are avaiable for retrofitting for cheap
[01:13:19] <CaptHindsight> ssi: http://a.abcnews.com/images/Entertainment/KABC_plane_crash_ford_inset_jef_150305_16x9_992.jpg how slow do you think he was going when crashed?
[01:13:23] <_methods> your lathe should be fine though
[01:13:31] <_methods> i'm talking about real small lathes
[01:13:32] <zeeshan> _methods i have videos of me cutting 304
[01:13:39] <zeeshan> and it was so cool!
[01:13:44] <zeeshan> something changed after i cnc'ed it
[01:13:46] <CaptHindsight> https://localtvwtvr.files.wordpress.com/2015/03/ktla-air-plane-crash_-possibly-harrison-ford-3.jpg?w=770
[01:13:50] <zeeshan> i think i messed up the gib adjustment
[01:14:01] <zeeshan> and to be honest, i dont know how to set gibs properly.
[01:14:05] <_methods> that's what i think youre seeing
[01:14:09] <zeeshan> the way i've done it is i tighten the gib
[01:14:16] <zeeshan> move the axis , if axis is too hard to turn
[01:14:20] <zeeshan> you releasse a bit of tension
[01:14:25] <zeeshan> till its smooth
[01:14:49] <Cromaglious> zeeshan, pretty much...
[01:14:50] <zeeshan> CaptHindsight: he pulled an indiana jones
[01:15:05] <zeeshan> crom ill try tightening it on the tighter side
[01:15:06] <zeeshan> and see
[01:15:24] <zeeshan> btw a video for you guys
[01:15:25] <zeeshan> https://www.youtube.com/watch?v=cKFkEFeXjOY
[01:15:29] <zeeshan> 1440 p watch it!
[01:15:31] <zeeshan> and fast forward
[01:15:33] <zeeshan> isn't this COOL
[01:17:05] -!- Crom [Crom!~Robi@pool-108-23-106-180.lsanca.fios.verizon.net] has joined #linuxcnc
[01:17:30] <Crom> main kb computer is buey generating tool path
[01:17:40] <Crom> busy
[01:19:59] <_methods> and is your tool on centerline? below center? how did you set it in the toolholder?
[01:20:07] <zeeshan> thats a good q
[01:20:12] <zeeshan> in the beginning it was too high
[01:20:14] <_methods> sometimes you'll see that if the workpiece rides over the tool
[01:20:24] <zeeshan> what i did was i used a ruler yesterday night
[01:20:35] <zeeshan> between the insert and the work piece
[01:20:38] <_methods> yeah
[01:20:42] <zeeshan> and got it as straight as possible
[01:20:53] <zeeshan> i put it slightly below center line
[01:20:57] <zeeshan> which i think is what you want..
[01:21:21] <zeeshan> cause if its too high, then you rub in the clearance face
[01:21:28] <_methods> that's one of those apple vs pc wars
[01:21:33] <zeeshan> haha
[01:21:35] -!- swingley has quit [Ping timeout: 256 seconds]
[01:21:40] <zeeshan> well it helped a bit
[01:21:44] <_methods> but as long as you set it on centerline or just below you should be fine
[01:21:44] <zeeshan> but still didnt fix the problem
[01:21:51] <zeeshan> i think it reduced the cutting forces a bit, thats why it helped a bit
[01:22:12] <MacGalempsy> zeeshan: that has to be the most boring youtube video ever
[01:22:18] <zeeshan> MacGalempsy: rofl
[01:22:27] <zeeshan> its unlisted for a reason
[01:22:38] <zeeshan> thats my research topic, dont call it boring!

[01:23:22] <zeeshan> itll be a bit more interesting in the coming months
[01:23:25] <zeeshan> ill have 3d simulation
[01:23:29] <zeeshan> 3d measurement i mean
[01:23:43] <zeeshan> so you'll see it self heal after cuts
[01:23:50] <MacGalempsy> nice
[01:24:06] <CaptHindsight> self healing fake mole?
[01:24:18] <zeeshan> fake mole? :D
[01:24:30] <zeeshan> btw, on a completely differnt topic
[01:24:37] <zeeshan> learned something interesting today in a course
[01:24:52] <zeeshan> always thought diamond was the hardest material..
[01:25:00] <zeeshan> so it would be the best material to cut say mild steel from
[01:25:07] <zeeshan> turns out, that assumption is completely wrong
[01:25:17] <MacGalempsy> I like the OTT P.D video.
[01:25:25] <zeeshan> a diamond tool cutting mild steel can only hold it's edge for about 2 minutes
[01:25:33] <zeeshan> i thought that was interesting
[01:26:14] <zeeshan> MacGalempsy: stop spying through my videos
[01:26:30] <CaptHindsight> http://en.wikipedia.org/wiki/Lonsdaleite
[01:26:36] <MacGalempsy> zeeshan: it started playing after the other one was finished

[01:27:13] <MacGalempsy> watching it was an attempt for me to redeem your movie making career
[01:27:19] <CaptHindsight> http://en.wikipedia.org/wiki/Fullerene#Fullerite
[01:27:20] <zeeshan> the point is just cause it's a hard tool doesn't mean it's the best cutting tool
[01:27:32] <zeeshan> MacGalempsy: ROFL
[01:27:42] <CaptHindsight> zeeshan: you make your points and I'll be makin my own points
[01:27:50] <zeeshan> CaptHindsight: sounds good!
[01:27:55] <zeeshan> the reason why diamond doesn't hold its cutting edge is kind of scientific
[01:27:59] <zeeshan> and i thought was interesting
[01:28:05] <CaptHindsight> and there's room enuff for the both of us
[01:28:15] <zeeshan> diffusion is the reason :P
[01:28:52] <bobo_> could a facing cut --vers Z axis cut seperate the source of problem /
[01:28:53] <zeeshan> mild steel has a high affinity of carbon, and diamond is like pure carbon, so it tries to steel the carbon from the diamond at higher temps
[01:28:53] <MacGalempsy> I know in drilling they can only use diamond bits in softer rocks becuase when drilling the harder stuff they wear too fast

[01:30:28] <zeeshan> bobo good idea to try!
[01:31:10] <zeeshan> MacGalempsy: hows your 5 axis project goin
[01:33:11] <MacGalempsy> it is only 4, but i took out the 4th axis to work on the homing sequence
[01:33:22] <zeeshan> rotary table?
[01:33:28] <MacGalempsy> yes
[01:33:30] <zeeshan> nice
[01:33:31] <CaptHindsight> zeeshan: so what you're saying is that if you supercool the diamond cutting tool it will last very long
[01:33:39] <MacGalempsy> last night I got a lesson in pullup resistors from the guys here
[01:33:55] <MacGalempsy> very thankful for that because my mind was spinning by the end of the night
[01:34:02] <bobo_> carbon sucking steel ---hence poly C ( ? ) PC ?
[01:34:11] <zeeshan> CaptHindsight: impossible to do on the sticking region of the cutting interface
[01:34:18] <zeeshan> theres no room for coolant to get in
[01:34:25] <zeeshan> unless you cryogenically submerse everything
[01:34:27] <zeeshan> while cutting it
[01:35:32] <zeeshan> bobo_: http://www.estig.ipbeja.pt/~pdnl/Sub-paginas/MatConst_apoio_files/ppt/Diagrama%20fase%20Fe-C.png
[01:36:01] <CaptHindsight> how do you mill with a phaser? They must have figured out some way to focus the energy
[01:36:03] <zeeshan> assume youre cutting 1018 steel, so .18 % carbon
[01:36:13] <zeeshan> you heat it up to austenizing temperature during metal cutting
[01:36:19] <zeeshan> it'll try to form auteniste
[01:36:34] <zeeshan> cause austenite has a solubility of 2.14% of C
[01:37:08] <zeeshan> depending on how you cool it now
[01:37:35] <zeeshan> it might form different compounds, but the carbon hunger comes from the solubility
[01:39:13] <CaptHindsight> zeeshan: have you gotten any of these? http://switz.tripod.com/spock-5.jpg
[01:39:41] <zeeshan> nope :(

[03:35:23] <furrywolf> also, whomever told me the shopmaster mt3 extension accepted a drawbar was apparantly mistaken... it's solid with a tang on the back, just like my other extension.

[03:44:27] <zeeshan> this metal cutting physics class
[03:44:27] <furrywolf> was $20ish. lol
[03:44:36] <zeeshan> really goes to show you that the most important face is the rake face
[03:44:41] <zeeshan> and then the clearance angle
[03:45:00] <zeeshan> and the cutting edge radius
[03:45:00] <furrywolf> I'm annoyed at the shopmaster mt3 extension... I'd swear someone here told me it was hollow and could be used with a drawbar, rather than solid and tanged...
[03:45:31] * furrywolf doesn't have enough money to buy tooling that won't work. :(
[03:50:13] <Cromaglious> I said I couldn't tell
[03:50:34] <Cromaglious> is it soft enough to bore out?
[03:51:10] <furrywolf> dunno
[03:51:52] <furrywolf> hopefully it fits my machine at least... tanged tools don't seem to fit, but since it's from the same company as the machine, it had better fit. (but, being china, selling accessories that don't actually work is routine business...)
[03:53:08] <furrywolf> well, some fit, some don't. my tanged jacobs chuck does fit
[03:53:54] <Cromaglious> compare the tang of the Jacobs to the tools that don't... see how much thinner the tang needs to be
[03:54:28] <furrywolf> I think it's an overall length issue. they bottom out before the taper seats. I can probably fix them with an angle grinder pretty quickly.
[03:54:40] <Cromaglious> ahhh too olong
[03:54:58] <jdh> I had to cut off one to fit my small chinese tailstock
[03:55:16] <furrywolf> I need collets next, but the cheapest I've been able to find is around $40 for the collets and $30 for the chuck, which is a lot of money...
[03:55:51] <Cromaglious> yeah, I need a mill... not that crappy 3040
[03:56:04] <furrywolf> what's a 3040?
[03:56:09] <Cromaglious> I'm keeping my eyes out for a X3

[03:58:20] <furrywolf> ah, one of those chinese routers
[03:58:29] <furrywolf> it probably has a larger working area than my shoptask...
[03:59:16] <furrywolf> I only have 10x11 or so
[04:01:29] <Cromaglious> is yours rigid enough for steel?
[04:01:46] <furrywolf> with reasonably shallow cuts
[04:02:18] <furrywolf> hrmm, I need to take a new photo. http://fw.bushytails.net/shoptask02.jpg is now CNC, and a bit cleaner...
[04:03:50] <Cromaglious> The 3040 isn't even rigid enough for over 0.002 cuts into aluminum
[04:04:00] <furrywolf> the extension visible in that image, under the socket set, doesn't fit the machine.

[05:17:46] <zeeshan> no p seems weird
[05:18:38] <MacGalempsy> thats what I thought. so going back through the calibration, I have been messing with D and FF1 and FF2
[05:20:28] <MacGalempsy> P should atleast be 1?
[05:20:52] <zeeshan> well
[05:21:03] <zeeshan> for me to personally understand the P term
[05:21:07] <zeeshan> i have to go back to the control basics
[05:21:31] <zeeshan> if im telling the motor to move by 5mm
[05:21:42] <zeeshan> and its going to 1mm
[05:21:52] <zeeshan> i know i need a Kp values of 5
[05:21:54] <zeeshan> *value
[05:23:25] <MacGalempsy> so P doesnt have to be an integer
[05:23:35] <zeeshan> nope
[05:23:43] <MacGalempsy> ok. that changes things

[05:24:15] -!- swingley has quit [Ping timeout: 250 seconds]
[05:25:22] <zeeshan> duhh , its the ratio of error
[05:25:25] <zeeshan> between output to input
[05:26:09] <zeeshan> which makes sense
[05:26:20] <zeeshan> cause the more the proportional gain
[05:26:22] <zeeshan> the faster the response
[05:26:26] <zeeshan> cause its a multiplier of error
[05:26:45] <zeeshan> having a P of 0 doesnt make sense
[05:26:50] <zeeshan> cause you'll always have some error in a system
[05:26:53] <MacGalempsy> what is this mm thing that everyone keeps talking about :/
[05:26:58] <zeeshan> mm?
[05:27:01] <zeeshan> millimeter? :p
[05:27:02] <MacGalempsy> j/k
[05:27:13] <MacGalempsy> its a SAE joke
[05:27:16] <zeeshan> haha
[05:27:25] <zeeshan> im trying to get used to mm cause a lot of research is done in si units
[05:27:29] <zeeshan> and im so used to imperial
[05:27:31] <zeeshan> it sux :/
[05:28:34] <MacGalempsy> my granddad was an aerospace machinist, so he always bagged on metric, then going to school they bag on imperial, now in the oilpatch everyone uses imperial
[05:29:05] <zeeshan> hehe
[05:29:11] <MacGalempsy> try going from liters to acre/ft and its a beotch
[05:29:32] <MacGalempsy> not acre/ft but acre*ft
[05:30:22] <zeeshan> what kind of unit is this
[05:30:27] <zeeshan> area / length
[05:31:43] <MacGalempsy> area* length is used for reservoir calculations
[05:32:22] <MacGalempsy> a large area (can be reduced to ft^2) and a depth of ft, so ultimately it comes to ft^3
[05:32:49] <MacGalempsy> this would be a method to say I have 10acres with 1ft of oil
[05:33:00] <zeeshan> ah
[05:33:01] <MacGalempsy> then you convert to barrels

[07:12:39] <Oldmanbeefjerky> hi, anyone here? im not much in the loop i wanna know if any hobbyist steel workable cnc mills have been invented yet? recently on my facebook newsfeed ive been seeing allot of cafuffle about cnc's made for making guns, figured those would probably be able to mill steel
[07:13:05] <Oldmanbeefjerky> that said im definitely not planning on making guns, i live in australia, we have like 1 gun shop per state
[07:13:14] <Oldmanbeefjerky> no ammo
[07:13:15] <archivist> invented!
[07:13:55] <archivist> small hobby mills are on sale to the model engineer crowd
[07:13:55] <Oldmanbeefjerky> keeping in mind when i say for hobbyist i mean something that doesnt cost in the tens of thousands
[07:14:06] <Oldmanbeefjerky> ooh

[07:19:38] <archivist> its small 20kg
[07:19:58] <Oldmanbeefjerky> no ive seen a mill like that in person, the bed had motors on it
[07:20:15] <Oldmanbeefjerky> is what i was getting at
[07:20:31] <archivist> a cnc one?
[07:20:45] <Oldmanbeefjerky> it looked like the seig only way bigger
[07:21:00] <archivist> http://www.arceurotrade.co.uk/Catalogue/Machines-Accessories/CNC-Milling-Machines/Sieg-KX1-CNC-Hobby-Mill
[07:21:39] <archivist> that just has safety casing covering a basic machine
[07:21:52] <archivist> with the motors too
[07:22:40] <archivist> but I would not get that as it uses an expensive driver board USB and mach3
[07:23:04] <archivist> there are cheaper conversions where you can use linuxcnc
[07:24:02] <Oldmanbeefjerky> ooh that wasnt a controlled cnc
[07:24:11] <Oldmanbeefjerky> just got that

[07:29:10] <renesis> taig can do steel but you gotta go shallow and get feeds and speeds dialed in or it screams
[07:29:21] <renesis> like, youre going to want hearing protection on
[07:29:38] <Oldmanbeefjerky> i dont mind having to do everything slowly

[07:30:00] <syyl> you get sick of it in about a week
[07:30:01] <Oldmanbeefjerky> well, with steel anyway

[07:30:25] <Oldmanbeefjerky> well precision is a must
[07:30:35] <syyl> and then they day comes where you just want something finished _now_
[07:30:46] <Oldmanbeefjerky> i only need to do steel for mechanical parts

[07:31:42] <syyl> the taig looks like a machine
[07:31:43] <Oldmanbeefjerky> hey, given i have next to no knowledge on the matter, how would i go about making gears?
[07:31:49] <archivist> http://taig.com.au/webstore/
[07:31:55] <syyl> the sherline is always a bit toy-like
[07:31:59] <Oldmanbeefjerky> taig is in aus, i like that
[07:31:59] <renesis> ikr
[07:32:27] <Oldmanbeefjerky> one of the biggest issues i face in any project i try to start is gearing
[07:32:38] <Oldmanbeefjerky> making gearboxes and finding gears
[07:32:41] <archivist> Oldmanbeefjerky, OK I am a gear maker, now you need a rotary of some quality
[07:32:45] <Oldmanbeefjerky> of which i have never managed
[07:33:08] <Oldmanbeefjerky> rotary as in lathe? or some style of the affirmentioned mill?
[07:33:13] <archivist> I made my mill to make gears
[07:33:28] <archivist> a 4th axis on the mill
[07:33:34] <Oldmanbeefjerky> my goal is to make a 2-3 speed gearbox some day, sized for rc cars
[07:34:08] <syyl> https://dl.dropboxusercontent.com/u/24396704/Deckel%20G2/2011-12-05_21-04-40_323.jpg
[07:34:10] <archivist> you can just buy in gears and fit to shafts, you need a lathe
[07:34:11] <syyl> rotary axis
[07:34:16] <renesis> could just buy sprockets and shafts off the shelf and machine cases
[07:34:28] <renesis> sherline rotary table looks pretty cool
[07:34:48] * archivist would not get the sherline rotary
[07:35:01] <renesis> why not
[07:35:07] <archivist> vertex rotary HV4 is ok
[07:35:18] <renesis> is it more $$$?
[07:35:28] <archivist> similar or less
[07:35:37] <renesis> neat
[07:35:56] <Oldmanbeefjerky> i see
[07:36:07] <archivist> Vertex has a real specification for rotary accuracy that none of the others have
[07:36:11] <renesis> archivist: does it come nema ready?
[07:36:21] <Oldmanbeefjerky> i find gears to be quite costly and also selection is limited
[07:36:27] <archivist> no you need an adapter tube
[07:36:47] <Oldmanbeefjerky> anywho, what should i do> get a taig for around $1.1k and so up my own control system, or buy a complete package
[07:36:56] <syyl> then you will find cnc, a rotary axis and gearcutters way more costly
[07:36:58] <syyl> :)
[07:37:01] <archivist> Oldmanbeefjerky, there are a few online sellers of low cost gears
[07:37:20] <archivist> HPC is one
[07:37:25] <syyl> the price of a good gear cutter set will make you cry
[07:37:51] <archivist> a hobbing machine is the holy grail
[07:37:53] <Oldmanbeefjerky> if i really had to could i just normal mill?
[07:38:13] <archivist> you need to rotate accurately the blank
[07:38:23] <syyl> of course
[07:38:34] <syyl> gears where made on manual machines all the time
[07:39:00] <Oldmanbeefjerky> because now that i think about it i probably wont need to make that many gears
[07:39:38] <archivist> only linuxcnc (as far as I know) can cnc a hobbing machine at low cost http://www.collection.archivist.info/searchv13.php?searchstr=barber+colman
[07:40:26] <archivist> how many gears do you want :)
[07:41:01] <Oldmanbeefjerky> so about my other question, what should i do? get a completed package or buy a thousand dollar taig just without the controller, and possibly steppers either
[07:41:10] <archivist> and how small http://gears.archivist.info/gears/IMG_1214_th.JPG
[07:41:14] <Oldmanbeefjerky> then do myself
[07:42:07] <archivist> cutters can be £60 plus and many dont make cutters in the sizes you may want
[07:42:52] <archivist> if you want helical gears then it is another can of worms
[07:43:07] <Oldmanbeefjerky> well for me cutters is no longer an issue
[07:43:32] <Oldmanbeefjerky> so about the taig setup
[07:43:43] <archivist> you have a stack?
[07:44:11] <archivist> down to what module
[07:44:23] <archivist> or DP
[07:44:42] <syyl> everytime i would have to cut gears
[07:44:58] <syyl> first I shop the retailers for an availible gear
[07:45:10] <syyl> then I look trough my module cutters
[07:45:12] <syyl> curse
[07:45:17] <syyl> and change my design ;)
[07:45:38] <Oldmanbeefjerky> from what i am taking in, they are charging $1k for the control system and steppers
[07:45:51] <Oldmanbeefjerky> and selling a setup without it but ready
[07:46:00] <archivist> my local gear stockist http://www.hpcgears.com/
[07:46:12] <syyl> hr, youre lucky
[07:46:15] <syyl> :)
[07:46:36] <Oldmanbeefjerky> oh dang i was looking at the usa site
[07:46:55] <syyl> keep in mind that you want ball screws for the cnc
[07:47:11] <syyl> its not just a matter of nailing motors to a manual milling machine
[07:47:37] <archivist> you dont need ball screws IF you write unidirectional g code
[07:47:53] <syyl> ok yes
[07:48:03] <syyl> but then you dont have the possibility to climb cut
[07:48:27] <archivist> all my gear cutting code is unidirectional except for the bevel generator
[07:49:11] <archivist> climb on a taig....
[07:50:42] <Oldmanbeefjerky> aww man, in australia a cnc ready stepper/controllerless setup costs $2k
[07:50:44] <archivist> german gear stockist http://info.maedler.de/
[07:51:00] <syyl> thats the go-to gear guy here
[07:51:03] <archivist> but your $ is 50p
[07:51:58] <archivist> I see the low value au $ when I get a donation for a manual scan
[07:53:20] <archivist> syyl, I got some deckel manuals the other day DC 30 and 40
[07:53:38] <syyl> d30?
[07:53:45] <syyl> thats one of the bigger machining centres?
[07:53:49] <archivist> yes
[07:53:53] <syyl> or machine cell
[07:54:09] <syyl> cool :D
[07:54:18] <syyl> dont see those very often

[09:21:17] <archivist> the reason is flexible column
[09:21:21] <Oldmanbeefjerky> ah
[09:21:27] <Oldmanbeefjerky> is this purely asthetic?
[09:21:31] <archivist> why I boxed mine up
[09:21:34] <Oldmanbeefjerky> superficial*
[09:22:02] <archivist> vibration and real bending under cutting load
[09:22:19] <Oldmanbeefjerky> oh
[09:23:02] <archivist> I still want to make mine better

[09:25:53] <Oldmanbeefjerky> this is an issue that requires you do slow down the cutting isnt it
[09:26:36] <archivist> if you slow too much and have too light a cut, you start rubbing
[09:27:27] -!- swingley has quit [Ping timeout: 252 seconds]
[09:27:40] <archivist> if rubbing then the machine is bending out the way
[09:29:07] <archivist> it is educational to have a dti on the table set it to 0 resting on the head, lean on the column see how far it moves
[09:29:51] <Oldmanbeefjerky> dti?
[09:30:04] <archivist> dial test indicator
[09:30:10] <Oldmanbeefjerky> oh
[09:30:56] <archivist> mine was moving about 5 thou before the stiffening
[09:31:32] <Oldmanbeefjerky> ah right i see
[09:31:34] <Oldmanbeefjerky> damn
[09:33:02] <archivist> some of the cheap mills are U section columns probably
[09:33:58] <Oldmanbeefjerky> in any case it seems i dont have enough money to outright buy a working mill
[09:34:35] <Oldmanbeefjerky> and trying to fix one within price range comes at the risk of it not being any good even when it works
[09:37:56] <archivist> any scrap yards near?

[09:39:26] <archivist> one local Boxford went for £300
[09:40:03] <Oldmanbeefjerky> its all super heavy mining stuff here, mills dont get sold, they get scrapped when the business changes over
[09:40:04] <archivist> I put linuxcnc on it for the owner
[09:41:21] <Oldmanbeefjerky> what im getting at is every business with a mill uses massive mills

[12:24:13] <SpeedEvil> And Standard Oil got broken up
[12:25:29] <Tom_itx> apparently it's old news?
[12:25:33] <Tom_itx> just got an email...
[12:25:47] <SpeedEvil> It's been a couple of weeks, I guess.
[12:25:52] <SpeedEvil> It's a retarded upgrade.
[12:26:12] <SpeedEvil> They simply boosted the CPU and RAM, and lefft the IO alone
[12:26:41] <Tom_itx> i didn't have one in my plans anyway
[12:26:52] <SpeedEvil> So, all four USB ports, and the 100mbit network - are all connected through a power-hungry network-hub chip to one solitary USB port
[12:29:32] <CaptHindsight> the pi isn't about IO it's about getting dev platforms into the hands of starving children so that they can learn to code
[12:30:36] <CaptHindsight> does anyone actually expect them to learn how to code on old pc's?
[12:31:35] <Tom_itx> yes
[12:31:57] <Tom_itx> boot it with cpm
[12:39:25] <CaptHindsight> http://www.raspberrypi.org/blog/archive/ look at what they have accomplished, sold >5m units, piano stairs, games, lots of birthdays, and just recently an illuminated pedalboard!

[12:42:14] * SpeedEvil sighs.
[12:42:27] <SpeedEvil> It could have been an awesome platform, and they're going full retard.
[12:42:45] <MrSunshine> hahahahaha
[12:42:57] <SpeedEvil> Sorry, that was unkind.

[12:47:16] <CaptHindsight> http://www.extremetech.com/computing/148482-the-true-cost-of-a-raspberry-pi-is-more-than-you-think
[12:48:36] <CaptHindsight> if they gave kids smartphones they could teach them to code and track them at the same time

[12:50:14] <SpeedEvil> The low power argument completely goes away versus a second hand laptop
[12:50:24] <SpeedEvil> as practically any dispaly you use will use more
[12:55:51] <CaptHindsight> the Rpi proved that low cost is more important to most than open source and details like power supplies, cables the display, how do you transport it etc are issues that are far too complex to comprehend and analyze
[12:56:30] <SpeedEvil> And the Pi killed many other boards
[12:57:14] <SpeedEvil> If one platform has 5 million users, and is terrible - you're basically going to face a really, really hard challenge to sell boards - even at the same price - if you are starting out.
[12:59:48] <CaptHindsight> like the bananna pi and others with the same pinouts and form factors with better SOC's
[13:00:12] <SpeedEvil> The other more subtle issue is that it's killed all 'western' makers
[13:00:30] <CaptHindsight> sounds like broadcon
[13:01:03] <SpeedEvil> While in principle you can do a banana pi, if you live in china, have good access to the chinese supply chain, and already have a well-capitalised plant - you're not going to be doing the same in the west.
[13:01:49] <SpeedEvil> (for $35)
[13:01:50] <CaptHindsight> they have a program/philosophy called Beachhead, they have been doing this for years with cable modems, routers,switches for years

[16:13:17] <SpeedEvil> Do you mean starting from glass tubes, and a bottle of CO2?
[16:13:27] <SpeedEvil> In which case, not yet
[16:13:48] <_methods> i saw some thing on hackaday.io where someone was building their own tube lol
[16:13:56] <HSD> Heh just read that yesterday
[16:14:23] <HSD> I want to build one, but buy the tube and lenses. So perhaps assemble is a better word?
[16:14:24] <HSD> :)
[16:14:26] <_methods> not sure if they ever got it working
[16:14:29] <HoloPed> SpeedEvil, started with a CO2 laser on ebay and built the rest - Frame, linear motions, etc
[16:14:42] <HSD> How much did it end up costing?
[16:14:51] <HoloPed> like this
[16:14:52] <HoloPed> http://openbuilds.com/threads/v-slot-co2-laser-60-100w.617/
[16:15:28] <SpeedEvil> You can do silly laser cutter very easilyt
[16:15:36] <SpeedEvil> If you don't bother with the beam folding
[16:15:48] <SpeedEvil> and just either move the workpieve under a static tube, or move the tube
[16:15:49] -!- erictheise has quit [Quit: erictheise]
[16:16:33] <SpeedEvil> This does of course make making it into a compact machine basically impossible - but do you care if it's 6 foot, not 2 feet tall - if you're not moving it
[16:16:41] taruti_ is now known as taruti
[16:17:55] <HoloPed> SpeedEvil, what is a workpieve ?
[16:18:03] <HoloPed> aren't the tubes water cooled ?
[16:18:04] <SpeedEvil> workpiece
[16:18:07] <SpeedEvil> I can't spell
[16:18:09] <SpeedEvil> yes
[16:18:11] <HoloPed> right
[16:18:15] <SpeedEvil> Well - type
[16:18:22] <SpeedEvil> I don't think workpiece is spelled with a v.
[16:18:38] <HoloPed> so moving the tube instead of a set or mirrors, thats the idea ?
[16:18:45] <HoloPed> and mounting the tube vertically ?
[16:18:46] <SpeedEvil> And yes, they are water-cooled.
[16:18:51] <SpeedEvil> Basically.
[16:19:01] <SpeedEvil> Moving the work is probably simpler.
[16:19:14] <HoloPed> depends on size, but yeah
[16:19:15] <HoloPed> I'
[16:19:27] <HoloPed> I've built a 3D printer, I'm not worried about the complexity of mirrors
[16:19:57] <SpeedEvil> I'm not saying that doing a folded optics is impossible - just that you now have to take into account various sorts of astigmatism, and tget the beam absolutely collimated right - over a variable path length
[16:20:00] <HoloPed> but I guess its one more thing that needs maintanence
[16:20:22] <HoloPed> I see what you mean
[16:20:26] <SpeedEvil> Yeah - it's at the very least worth considering if you actually want to bother with a folded path.

[16:50:45] <_methods> indeed
[16:51:42] <CaptHindsight> I've had customers ask for that for industrial items. They wanted the printer shipped to customers in a box, in a box in a box like their iphone was

[19:07:52] <ssi> having a lot of trouble with that :(
[19:08:01] <XXCoder> it is ard yeah
[19:08:11] <XXCoder> maybe build it in solvespace or something
[19:08:24] <XXCoder> something that can move parts so you can see limits and such
[19:08:42] <ssi> solvespace?
[19:08:57] <ssi> I've been trying to do it in solidworks but solidworks inside win7 inside parallels is being a huge turd for me :(
[19:08:59] <XXCoder> its amazing modeler yet pretty new

[19:10:06] <XXCoder> it will first test
[19:10:09] <XXCoder> oh
[19:10:20] <XXCoder> open source so maybe can make mac compitable
[19:10:28] <ssi> meh
[19:10:30] <XXCoder> its very new and developer is windows one
[19:10:30] <ssi> too much hassle :)
[19:10:42] <XXCoder> I want it to succeed because damn its good
[19:11:00] <XXCoder> maybe it will run better in parallels
[19:11:05] <XXCoder> than solidworks anyway
[19:11:41] <ssi> biggest problem I'm having with solidworks right now
[19:11:50] <ssi> I'm downloading sldprt files from mcmaster for tslot extrusion
[19:11:54] <ssi> and it renders HORRIBLY
[19:12:03] <_methods> yeah all those profiles
[19:12:13] <_methods> they're a nightmare lol
[19:12:23] <_methods> even on a real computer
[19:12:45] <ssi> I guess I don't have to model the tslot
[19:12:58] <ssi> but I was really hoping I could do some deflection analysis or something
[19:13:07] <_methods> i'll trade you a windows pc for one of your airplanes lol
[19:13:08] <XXCoder> can always do some points accurate shape, like accurate rod
[19:13:15] <XXCoder> and pretty good approx of supports
[19:13:19] <ssi> I don't want a windows pc!
[19:13:27] <_methods> hahahahah
[19:13:33] <ssi> shit I have a machine here under my desk that has two huge ridiculous video cards in it

[19:14:43] <_methods> i think they're all equally vulnerable anymore
[19:14:50] <XXCoder> yeah
[19:14:55] <XXCoder> I use windows 7 pc
[19:15:04] <_methods> the *nixes have been just as plague ridden lately
[19:15:08] <XXCoder> computer itself is pretty damn elderly at 9+ years old
[19:15:29] <XXCoder> good thing I had bought riciously overkill compuyter back then
[19:15:30] <ssi> so my last laser table was built from 20x40mm extrusion for the main frame, and 20x20 legs and everything else
[19:15:32] <_methods> i like the *nixes because i can use old hardware and still get good performance
[19:15:45] <ssi> but it was 2x4' work area, and around 33x60" overall
[19:15:52] <XXCoder> ssi: laser cnc I bet I can almost use just sbr itself as supports
[19:15:53] <ssi> I want the new one to be 4x8' work area
[19:15:59] <ssi> sbr?
[19:16:02] <_methods> rail
[19:16:02] <XXCoder> expecially X since it has sbr 20
[19:16:04] <_methods> round rail
[19:16:05] <XXCoder> yeah
[19:16:14] <_methods> with split bearings
[19:16:17] <_methods> supported rail
[19:16:23] <ssi> that might not be a horrible option
[19:16:37] -!- nerdfiles has quit [Ping timeout: 264 seconds]
[19:16:43] <ssi> well so I'm trying to decide if I want to build the frame itself from something like 40x80mm tslot, or just welded steel rectangle tube
[19:16:50] <XXCoder> its nice but if you buy chinsese shit ones, clear out bearings or buy usa ones and swap em.
[19:16:58] <_methods> steel is cheaper for sure
[19:17:08] <ssi> it's cheaper, but not tremendously so
[19:17:08] <XXCoder> and kess modifable
[19:17:22] <ssi> and building a decent FLAT table is going to be harder
[19:18:16] <_methods> indeed
[19:18:41] <ssi> and as far as extrusion goes, I'm pretty much limited to buying it from mcmaster
[19:18:45] <ssi> cause I can get it locally
[19:19:04] <XXCoder> I plan to just stright up buy from chinese
[19:19:07] <XXCoder> a frame
[19:19:18] <XXCoder> so I has working cnc to make bigger cnc
[19:19:20] <ssi> I thought about buying a cncrouterparts.com motion kit
[19:19:25] <ssi> but it's $4500
[19:19:29] <ssi> and not really optimized for laser
[19:19:49] <XXCoder> maybe it is better to just do 8020 yeah
[19:19:56] <XXCoder> tslot frame
[19:20:14] <XXCoder> since basically zero defection at cutting (besides weight of system)
[19:20:25] <jdh> and 1kw?
[19:20:30] <ssi> the system will be pretty light
[19:20:35] <_methods> lol
[19:20:36] <ssi> and there's no cutting forces
[19:20:43] <_methods> 80w
[19:21:06] <XXCoder> ssi: maybe get sbr rails for X
[19:21:13] <XXCoder> its very rigid and stright
[19:21:26] <XXCoder> it will help surface be flat
[19:21:35] <ssi> kind of expensive though
[19:21:50] <XXCoder> chinese its not too bad but buy usa bearings
[19:21:56] <ssi> I need 2800mm
[19:22:00] <ssi> and shipping that will be a nightmare :(
[19:22:39] <XXCoder> http://www.ebay.com/itm/250729742630 thats what I bought

[19:23:45] <XXCoder> 280 bucks for all that

[19:25:49] <XXCoder> somehow I recalled 1200mm
[19:26:31] <_methods> what are you gonna use?
[19:26:34] <_methods> that's a lot of rail
[19:27:00] <_methods> with no load on the head your could probably just use linear bearings and round rod
[19:27:07] <_methods> like a 3d printer head
[19:27:21] <XXCoder> yea
[19:27:24] <_methods> you just need something to keep deflection out
[19:27:31] <_methods> over that nightmare distance
[19:27:44] <XXCoder> sbr do give additioonal benefit on being very rigid
[19:27:50] <XXCoder> but 2800 mm wow
[19:28:22] <XXCoder> maybe some nice 1530 beams with bearing blocks
[19:28:33] <XXCoder> should be strong enough
[19:29:04] <XXCoder> dunno if can buy those blocks specifically for 1530 so maybe have to make

[19:29:46] <XXCoder> 450 shipped approx
[19:30:21] <ssi> my last machine was makerslide
[19:30:23] <ssi> it worked pretty well
[19:30:24] <_methods> http://www.igus.com/wpck/5365/drylin_r_awui
[19:30:27] <XXCoder> twice as many as you need... maybe build two and sell one off for profit enough to cover both lol
[19:30:31] <_methods> wonder how much that stuff goes for
[19:30:34] <ssi> the gantry was 54" long, and plenty rigid enough for what I needed
[19:30:58] <_methods> yeah makerslide may actually be the way to go
[19:30:58] <ssi> I was thinking I'd do a 54" gantry again, and then do 110" long rails, rigidly affixed to the frame
[19:31:02] <_methods> probably way cheaper
[19:31:04] <ssi> and I can get all the makerslide for like $200
[19:31:08] <_methods> belts and maker slide
[19:31:11] <ssi> yep
[19:31:16] <XXCoder> nice
[19:31:20] <XXCoder> never heard of it
[19:31:35] <ssi> what sucks is, the way I did it before and what I intended to do again
[19:31:37] <_methods> it's just alum extrusion with a v on it
[19:31:40] <ssi> is buy a shapeoko kit and then extra long rails
[19:31:48] <ssi> but they recently stopped selling the shapeoko kit
[19:31:54] <ssi> they have a new product that's preordering now
[19:31:57] <ssi> D:
[19:32:00] <XXCoder> dont see any 2800mm on one site I found
[19:32:01] <_methods> aren't the drawings open source
[19:32:07] <zeeshan> where is andypugh!
[19:32:08] <_methods> for all the shapeoko stuff
[19:32:10] <ssi> they sell 1000 and 1800mm
[19:32:13] <ssi> and they'd be pretty easy to join
[19:32:17] <ssi> _methods: yeah they are
[19:32:22] <ssi> but the kit was a convenient way to go
[19:32:25] <_methods> true
[19:32:29] <ssi> and I don't have a great way to make those plates
[19:32:31] <_methods> but it's all laser cut plates

[19:36:06] <ssi> it looks nicer
[19:36:14] <XXCoder> didnt know it was shapeoko
[19:36:25] <ssi> they probably won't release the design files for the xcarve stuff til after it's shipping
[19:36:51] <ssi> https://github.com/shapeoko/Shapeoko_2
[19:36:56] <ssi> that's the design stuff for the shapeoko
[19:36:58] <XXCoder> z axis screw isnt held on bottom part
[19:37:16] <ssi> I don't have a z axis so I don't care :)
[19:37:22] <XXCoder> I guess it needs software defines or something
[19:38:22] <ssi> so the other part of my design struggle
[19:38:26] <ssi> is the Z-bed
[19:38:40] <ssi> I need to make a decent, rigid frame that'll hold a 4x8' sheet of MDF
[19:38:49] <ssi> that's supported on four acme screws
[19:39:01] <ssi> I'm wondering if just the screws are enough, or if it needs linear guides as well
[19:39:22] <XXCoder> try deflection test on acme screws
[19:39:40] <XXCoder> you know what material you need to cut so can figure from there I guess
[19:39:55] <ssi> again, no cutting forces
[19:40:07] <XXCoder> no, the weight of stock on toop
[19:40:07] <ssi> and the acme screws will be vertical
[19:40:10] <ssi> so they dno't really deflect
[19:40:16] <XXCoder> no issue then
[19:40:26] <SpeedEvil> you mean for a Z bed?
[19:40:29] <ssi> I'm more wondering whether the table will move around slightly as the bed is raised and lowered if I don't have rail
[19:40:32] <ssi> SpeedEvil: yes
[19:41:05] <SpeedEvil> ssi: constraining it in xy is probably a good idea. This can be quite simple
[19:41:24] <SpeedEvil> Four drawer slides, and a couple of springs
[19:41:48] <ssi> SBR rail might be a good option for that part
[19:41:55] <ssi> I only need 12" of throw

[20:10:32] <FinboySlick> I'm a bit curious of what they mean by fiber-optics lasers though. I mean, it's pretty obvious that you can run a laser through fiber-optics but obviously they don't just mean taping the ends of fiber-optics cables side by side to make a 'bigger laser'.
[20:11:17] <CaptHindsight> it basically is that

[21:25:57] <ssi> with some slotting to takeup the gap
[21:26:01] <ssi> which I haven't modeled yet
[21:26:34] <ssi> could be three bearings instead of four
[21:26:42] <XXCoder> you just made those?
[21:26:46] <ssi> yep
[21:26:54] <XXCoder> damn it probably would take me hour lol still new
[21:27:19] <XXCoder> would you mill t slot in order tp have nice v groove?
[21:27:33] <ssi> nah I think a delrin V wheel would run in the radiused tslot just fine
[21:27:45] <XXCoder> yeah
[21:28:14] <ssi> and _methods seems to like the idea of running it horizontally like that, but I think the gantry will deflect less if it's vertical
[21:29:28] <XXCoder> bad case of white virus http://www.theloop.ca/store-owner-forgets-to-lock-up-overnight-customers-respond-in-the-most-canadian-way-possible/
[21:29:55] <_methods> yeah it may not be good up there like i was thinking
[21:30:05] <_methods> was an interesting idea
[21:30:32] <ssi> I think it's fine either way, but that 20x40 is gonna be MUCH stiffer in the 40mm direction than the 20mm direction
[21:30:42] <_methods> yeah
[21:30:42] <ssi> so just to minimize sag in the gantry, I think that'd be the way to go
[21:30:57] <XXCoder> ssi: maybe interesting idea for you - make your laser platform lower/rise cnc axis too
[21:31:09] <ssi> I don't want to move the motion up and down
[21:31:15] <ssi> because then I'd have to move the TUBE also
[21:31:20] <ssi> or else have an extra bend in the path
[21:31:20] <_methods> yeah
[21:31:22] <ssi> and that sucks
[21:31:24] <_methods> better to move the bed
[21:31:44] <XXCoder> hmm maybe not, but in least motorized lol but youre right
[21:32:10] <_methods> you don't want to be moving your beam path if you can avoid it
[21:32:25] <ssi> right
[21:32:26] <_methods> better to move the workpiece
[21:32:32] <ssi> all sorts of alignment issues there
[21:32:34] <_methods> yes
[21:32:45] <ssi> I got pretty good at aligning my beampath btw :)
[21:32:55] <ssi> it took me a little while at first, but I got VERY good at it
[21:32:56] <_methods> hehe i hate that
[21:33:03] <_methods> tweakin mirrors
[21:33:25] <ssi> also I never had a good method for aligning the mirror in the head before
[21:33:32] <ssi> but with a motorized Z I will be able to
[21:33:59] <ssi> anyway I'm gonna get on the road now
[21:34:00] <ssi> back in a bit
[21:34:06] <_methods> yeah i'm headin home

[23:27:48] <furrywolf> Jymmm: it's too late to start from seed here
[23:28:05] <furrywolf> seeds were about three months ago

[23:29:39] <furrywolf> again, it's too late. if you start from seed now, they won't ripen any fruit before next winter. the hot peppers all need a very long season...
[23:29:53] <furrywolf> to get hot peppers here, you have to start them indoors around the new year
[23:30:31] <Jymmm> Optimimally, yes. but you CAN do it semi off season too
[23:30:42] <Jymmm> Just not as high a yield.
[23:30:49] <furrywolf> ... I have been growing peppers here for a number of years. how long have you been growing peppers here for?
[23:31:21] <_methods> oh snap
[23:31:22] <Jymmm> your years plus one day.

[23:32:00] <Jymmm> furrywolf: So, do you wish to continue your drama fest, or just have a nice conversation?
[23:32:02] <furrywolf> some varieties will happily overwinter in the greenhouse. Manzanos are excellent at it, for example. but the really hot ones don't seem to make it through the winter, even in the greenhouse, and to get ripe fruit, you have to start the seeds very early. since I didn't get seeds started this year, I'm buying starts.

[23:33:44] <_methods> i know absolutely only one thing about peppers
[23:33:51] <_methods> they burn when they leave the building
[23:34:10] <Jymmm> _methods: the smaller they are, the nastier they are =)
[23:34:33] <furrywolf> I think this year the only hots I had survive are a few scorps... haven't cleared out the greenhouse and taken inventory yet though. they might be ghost, not scorp.
[23:34:46] <Crom_> Good thing I'm allergic to them
[23:35:36] <Crom_> No Nightshade's of any in my diet
[23:35:45] <Crom_> Kind
[23:36:08] <furrywolf> smallest I have are tepin, another variety which overwinters well... I've never gotten more than 2-3 peppers a season from them though, and they're the size of peas, which kinda limits their usefulness. I'm hoping to get a better harvest this year.
[23:36:33] <Jymmm> furrywolf: I want to be one of the million others that has their own colorfully named hot sauce. but unlike "Death", "Satan Sauce" etc, I want to name mine "Mommy". Cause that is what you will be calling for when you just get a wiff of it =)
[23:38:10] <Crom_> My wife grows some heritage tomatoes which she likes, now we have 4 volunteer plants in the backyard outside the planters
[23:40:53] <furrywolf> I've had bad luck with tomatoes here... blight is everywhere.
[23:41:32] <furrywolf> and I've yet to get a single melon, ever. I've given up trying. no cantaloupes, no watermelon, no muskmellon, no honeydew,... tried about 20 varieties, never a melon.
[23:41:50] <_methods> no melon zone
[23:41:52] <_methods> hehe
[23:41:58] <furrywolf> they either get grey mold, don't set fruit, or die before the fruit are more than marble-sized...
[23:42:20] <_methods> you need to play music for them
[23:42:23] <Crom_> We had 3 pumpkins, the biggest was 8"
[23:42:47] <PCW> We dont get enough heat for good melons but squash does really well
[23:42:49] <furrywolf> and that's both in the greenhouse and outside... they actually do slightly better outside, as the grey mold takes a little longer to hit...
[23:42:53] <Crom_> And lot of water
[23:43:59] <furrywolf> no, not lots of water. here you have to keep the top layer of soil dry. maybe lots of water, but delivered with drippers away from the stem.
[23:44:20] <furrywolf> if you let the plant or the top layer of soil get wet, the grey mold sets in.
[23:44:40] <Crom_> Love my summer squash, easier to buy the tasteless store bought squares
[23:44:47] <furrywolf> I'm not a squash fan...
[23:45:16] <Crom_> Wooo cnc pumkin carver

[23:53:12] <furrywolf> "We will Immediately leave you Positive Feedback within a few days." lol
[23:54:45] <furrywolf> I may or may not have a bunch of manzanos this year... I started some seeds last spring, but never got around to repotting them, so they've spent a full year in fertilizer-less rocky starting soil with no nutriants... they're about 10" tall, and close to pure white. but they are alive. I repotted them last week finally, will see if they turn green or not...
[23:55:10] <furrywolf> they don't like being in a little 6-pack tray for a year.
[23:56:08] <SpeedEvil> I have ~20 apple trees in various states of graft success I've got to repot this year
[23:56:26] <furrywolf> I haven't played with grafting... I've been tempted to try some pepper grafting.
