[00:30:44] <Tom_itx> anyway this is working good enough for any sherline i own
[00:31:10] <Tom_itx> it struggles at 10rpm
[00:31:22] <Tom_itx> but 100 and above it does ok

[00:39:16] <Tom_itx> i think if I gets too high, it wanders around the setpoint and never quite settles on it

[00:41:16] <zeeshan> i guess evertyhing is gray :p
[00:41:17] <Tom_itx> zeeshan what setup did you have when you graphed your pid?
[00:41:33] <zeeshan> for servo tuning?
[00:41:37] <zeeshan> for hal scope?
[00:41:40] <Tom_itx> yeah
[00:41:46] <Tom_itx> i thought about plotting my spindle
[00:41:51] <Tom_itx> just for kicks

[00:42:25] <zeeshan> hm2_5i25.0.7i77.0.1.analogout#
[00:42:35] <Tom_itx> what did you trigger on?
[00:42:52] <zeeshan> source channel 2 (which was the analogout one)
[00:43:04] <zeeshan> and just force the trigger first
[00:43:32] <zeeshan> then increase the gain on analogout, then move the position of the trigger so it does it @ the on ramp of the analogout
[00:44:02] <zeeshan> just force the trigger first <- quickly turn on your spindle after this
[00:44:39] <Tom_itx> you should be able to just have it trigger on something
[00:45:15] <zeeshan> i just "made it work"
[00:45:20] <zeeshan> didnt look at it too much into detail :(
[00:45:36] <Tom_itx> meh, i'm gonna write some tap code instead
[00:45:42] <zeeshan> about your question earlier
[00:46:04] <zeeshan> when we were analyzing higher order systems.. integral gain reduced the steady state error
[00:46:25] <zeeshan> but if you went overkill with the gain, youd get an excessively under damped system
[00:46:30] <zeeshan> er overdamped not under
[00:46:51] <Tom_itx> that's what i said... it will wander around the setpoint and never quite settle on it
[00:47:25] <Tom_itx> but with a low I term it will take longer to reach the setpoint
[00:47:51] <Tom_itx> maybe D will kick it in the arse
[00:48:00] <Tom_itx> it's not too bad like it is really
[00:48:11] <Tom_itx> helluva lot better than without
[00:48:20] <zeeshan> are you tuning a velocity loop
[00:48:28] <Tom_itx> i was
[00:48:33] <zeeshan> why
[00:48:40] <zeeshan> =D
[00:48:47] <zeeshan> to fix your too slow rpm thing?
[00:48:50] <Tom_itx> for spindle speed control
[00:49:00] <Tom_itx> it's pretty close now
[00:49:21] <zeeshan> nice
[00:49:22] <Tom_itx> before i added pid it wouldn't even spin less than S500
[00:49:24] <zeeshan> post some graphs! :P
[00:49:35] <Tom_itx> now i can get S10 but it wanders around it
[00:49:42] <zeeshan> ill be back, my drawbar is on the hydraulic press under pressure

[00:55:39] <malcom2073> It was done by the guy who started solidworks, it actually feels very similar to solidworks.
[00:55:43] <Tom_itx> i don't need no cloudy day

[03:01:54] <Tom_itx> do you have parport?
[03:02:00] <Tom_itx> why not a 7i90?
[03:02:07] <furrywolf> I have parport now, on a laptop.
[03:02:29] <Tom_itx> will the laptop run lcnc ok?
[03:02:33] <Tom_itx> i kinda doubt it
[03:02:46] <furrywolf> excellent latency as long as I don't do anything that triggers any part of the power management
[03:02:59] <Tom_itx> turn it all off
[03:03:07] <furrywolf> or initialize a video. (playing is ok, just can't initalize it)
[03:03:08] <Tom_itx> is it a standard parport?
[03:03:10] <Tom_itx> epp
[03:03:15] <furrywolf> none of it can be turned off
[03:04:03] <furrywolf> <14us no matter how hard I abuse it... 100,000us if I change the screen brightness, switch to battery, etc. heh.
[03:04:43] <Tom_itx> get that 7i90 parport card, it's cheap
[03:04:56] <Tom_itx> no guarantee your parport will work on it
[03:05:04] <Tom_itx> if it's standard it should
[03:05:41] <Tom_itx> i'm using the 7i90 with a 7i47 daughter card
[03:05:46] <Tom_itx> 7i47S now
[03:05:50] <Tom_itx> spindle control
[03:06:10] <furrywolf> I decided a 7i76e would be a good fit for the machine and computer.
[03:06:37] <Tom_itx> i decided the 7i90 was a good fit for my wallet
[03:06:48] <Tom_itx> 72 io
[03:07:58] <furrywolf> still adds up to $130, and I'm still stuck with parport.
[03:08:17] <Tom_itx> how's that a problem?
[03:09:22] <furrywolf> I'm still stuck with needing realtime timing on a laptop, a bulky cable, and no upgrade path to anything newer.
[03:09:49] <furrywolf> and I seem to recall the 7i76e having better i/o in some fashion, but I could be wrong on that.
[03:09:52] <Tom_itx> you would need that on the ether card too
[03:10:06] <Tom_itx> it's just a different interface
[03:10:19] <Tom_itx> afik
[03:10:19] <furrywolf> I'd need what?
[03:10:35] <Tom_itx> rt timing
[03:10:49] <furrywolf> no, the ethernet boards only need a servo thread, no base thread.
[03:10:58] <Tom_itx> same with all mesa cards
[03:11:06] <Tom_itx> i run a servo thread only

[03:13:37] <Tom_itx> both these asrock boards have parport

[03:14:32] <Tom_itx> oh btw, the 7i90 has 3 interfaces
[03:14:43] <Tom_itx> i'm using the parport
[03:14:48] <furrywolf> and I have no plans to set up a complete computer to go with my portable tabletop mill on a rolling cart.

[03:21:12] -!- XXCoder1 has quit [Ping timeout: 252 seconds]
[03:22:49] <furrywolf> I have a cnc sherline mill (the tiny one with only 3" of Y), a manual sherline lathe (tiny and old), and a shoptask lathe/mill combo machine (chinese).
[03:23:44] <furrywolf> the sherline is set up with flashcut. it needs to be linuxcnc one of these days, as flashcut is utter shit, but it works.
[03:23:50] <Tom_itx> 3" isn't much travel :)
[03:24:03] <Tom_itx> i know i used it for a long time
[03:24:06] <furrywolf> no, it's not. and it's the main reason I don't like my sherline.
[03:24:12] <Tom_itx> last ver i had was 1.41
[03:24:31] <furrywolf> they make a same-style mill with 5", and they make the multi-directional mill with even more.
[03:24:34] <Tom_itx> control is in a box now
[03:24:51] <Tom_itx> i've got the multi directional
[03:24:59] <Tom_itx> it's kinda flimsy but has more travel
[03:25:01] -!- per_sonne_ has quit [Ping timeout: 250 seconds]
[03:25:04] <furrywolf> you have more Y than I do.
[03:25:17] <Tom_itx> i can get 7x9 if i work at it
[03:25:57] <furrywolf> yes. I have 3", barely. if there's any swarf on the ways I don't.
[03:26:13] <furrywolf> because the swarf jams between the saddle and the column or handwheel mount.
[03:26:34] <Tom_itx> well i built my control with the idea of a bigger mill later down the road
[03:26:49] <Tom_itx> so everything but maybe the steppers can be ported
[03:26:57] <Tom_itx> might need bigger steppers
[03:27:03] <Tom_itx> the drivers are all ok
[03:28:05] <furrywolf> I've built the control for my shoptask with the idea that it might be good for a bigger mill. :)
[03:29:25] <furrywolf> the control on my sherline is undersized. motors run cold. flashcut--
[03:29:34] <Tom_itx> i think i'm pretty much ready to put the mill back together now
[03:29:51] <Tom_itx> i've been bench testing the control for quite a while with just the spindle
[03:30:05] <Tom_itx> the rest was working when i took it apart
[03:30:36] <Tom_itx> modded the spindle pulleys etc added the encoder so i could do sync motion and pid spindle control

[03:38:33] <treid> different model mother boards, I used the same power supply
[03:38:52] <furrywolf> try a different power supply, although with two motherboards I doubt that's it.
[03:39:08] <treid> I do have another PS I can try with

[03:43:03] <treid> I get a solid green LED on the mobo normally. It goes to a faintly blinking LED when I plug the card in
[03:43:12] -!- sumpfralle has quit [Ping timeout: 252 seconds]
[03:43:17] <treid> this is with the mobo not powered on, just the PSU on
[03:43:23] <treid> so definitely something weird with the card
[03:44:07] <furrywolf> sounds like the card is shorting the power supply
[03:44:27] <furrywolf> make sure there's no obvious damage to it (broken off capacitors, etc), then tell mesa you need a new one.
[03:45:53] <furrywolf> you have nothing plugged into the card, right?
[03:46:11] <treid> correct
[03:47:43] <furrywolf> looks like it has a jumper to disable pci, but I doubt anything other than shorting the power supply could kill the power-to-mobo led.
[03:50:15] <treid> alright I'm super dumb
[03:50:22] <treid> I was plugging it in backwards
[03:50:46] <furrywolf> ... lol?
[03:50:59] <treid> didn't even consider that was possible
[03:51:36] <furrywolf> it shouldn't be, unless you've taken off the bracket, or are using a tiny sbc motherboard...
[03:51:55] <treid> I took off the bracket because it interfered with the mobo
[03:52:08] <treid> mini-atx intel atom board
[03:55:19] <furrywolf> if you take it off, you should remember which side it was on. lol
[03:55:31] <furrywolf> and did it only interfere because you were trying to put it in backwards? :P
[03:56:12] <treid> nah the slot is parallel to the edge so it would have to come off either way
[03:56:44] <treid> I think I might have caused an issue with that small mobo, won't power on anymore. The bigger mobo boots up with card now though
[03:56:55] <treid> putting this machine together is going to be long process...
[03:57:10] <furrywolf> yeah, it's quite possible you damaged the mobo doing that.
[03:57:24] <treid> better the mobo then the card
[04:00:51] <furrywolf> it's also quite possible you damaged the card...

[04:01:34] <treid> Yeah hard to say at this point
[04:02:07] <treid> all I know is that the mobo powers on, I don't have a graphics card on the large mobo so I can't hook a monitor up at the moment to continue on

[04:02:54] <treid> I bought that board a couple years ago for linuxcnc. at the time it seemed like one of the best options
[04:03:03] <renesis> was in a shop at work when it happened, no idea how, its possible it got plugged into 220v because some of the sockets were wrong in there

[04:03:19] <treid> is there a better choice than the atom out there now?
[04:03:33] <renesis> pcw says theyre shit but mine got like heroic scores on latency test and i never had issues running my stepper mill
[04:03:48] <furrywolf> I've seen way too many 120V outlets wired for 240V. I have no idea why people do this, instead of spending the $5 for the proper outlet and plug combo.
[04:03:52] <renesis> so i dunno maybe its a feedback latency issue hes referring to, mines open loop

[04:04:47] <renesis> furrywolf: sometimes i think its confusion because theres high current 120V that look like in between
[04:05:45] <furrywolf> no, it's lazyness. I've often seen well pumps and such wired that way. "well, this is what I have in my toolbox..."
[04:05:53] <renesis> when i see it, its usually the keyed looking 120v slot, with the horizontal slot sticking out of the verticle
[04:06:02] <renesis> well laziness or ignorance
[04:07:30] <renesis> the 50A 120V output let got me for testing amps at one job was pretty badass
[04:07:40] <renesis> big giant twist lock thing
[04:07:46] <furrywolf> at least around here, be very, very wary of plugging tools into any outlet that looks like it might have ever gone to a well pump.
[04:08:06] <renesis> this was in a building full of electronic engineers
[04:08:16] <renesis> tho to be fair, they werent allowed in the shop
[04:08:16] <furrywolf> I just got a jobsite box that uses 50A 125/250V twistlocks. they're like the 120V 50A twistlock, but bigger, and metal.
[04:08:34] <renesis> cool
[04:08:51] <renesis> i dont think im ever going to use IEC for anything personal anymore
[04:09:05] <renesis> and if its my call on some work shit, i wont
[04:09:40] <renesis> locking iec is like, rare unicorn shit, and neutrik powercon seems to be fine

[04:12:29] <renesis> im surprised its not a server psu standard, kind of sad locking IEC is not standard for consumers
[04:12:52] <renesis> like, whole work connected by computer power cables that will fall out if you wiggle them a little
[04:13:08] <furrywolf> I'd settle for cords that actually made reliable contact. so far they can't even get this right.
[04:13:30] <furrywolf> once they figure out how to make spring contacts, then locking would be nice.
[04:14:06] <renesis> dunno never heard of a problem with qsc ones
[04:14:24] <renesis> this is what i would use now
http://www.neutrik.com/en/audio/powercon/
[04:14:56] <renesis> the only downside is that they look like neutrik speakon connectors, but they wont physically mate so who cares
[04:15:46] <furrywolf> I used trailer connectors for some speakers here. :P
[04:16:28] <renesis> long as theyre airtight, shrug

[12:49:42] <MarkusBec> i think the deebian wheezy iso used a 3.x kernel
[12:49:47] <MarkusBec> with rtai
[12:55:05] <JT-Shop> debian wheezy uses 3.4-9-rtai-686-pae
[12:55:28] <msantana> JT-Shop: I knew these pages. However, they only describe the installation with kernel 2.6.x

[12:56:28] <msantana> JT-Shop: ok, thanks
[12:56:28] <JT-Shop> msantana, are you wanting to do something special with a kernel?
[12:56:42] <msantana> no I don't
[12:56:55] <JT-Shop> just use the debian live cd
[12:57:58] <msantana> I just want to install on my pre-installed debian
[12:58:39] <msantana> wanted :]
[12:59:23] <JT-Shop> debian wheezy?
[13:00:11] <JT-Shop> I don't see an install script for wheezy
[13:01:05] <msantana> no, Jessie
[13:01:48] <JT-Shop> I don't see any info on jessie
[13:04:32] <msantana> JT-Shop: Is the any script for installation on any version of Debian?
[13:04:45] <msantana> there
[13:04:55] <MarkusBec> msantana: possibly it's not a good idea
[13:04:57] <JT-Shop> don't see any
[13:05:09] <JT-Shop> are you going to control a machine with this?
[13:05:22] <MarkusBec> exept you are a debian kernel dev :)
[13:06:18] <MarkusBec> msantana: you have to compile all by hand
[13:06:30] <msantana> MarkusBec: I understand
[13:06:58] <MarkusBec> and no other linuxcnc user oder dev had tested it on jessie
[13:08:38] <msantana> So, which is the recommended kernel version? Just install the version from Live CD and don't upgrade anything?
[13:08:51] <MarkusBec> yes
[13:09:06] <JT-Shop> that is the easy way

[13:12:24] <msantana> and sorry for mentioning EMC2 when I should say LinuxCNC :)
[13:13:18] <MarkusBec> msantana: preempt is a good choice with mesa card but possibly to slow for SW stepgen

[13:13:59] <harold> norias:
https://www.youtube.com/watch?v=Lr6bP0mBjK4 this thing is pretty good if it can aluminum like this, and cost only $2500, no?
[13:14:39] <Tom_itx> JT-Shop, any glitches with your plasma running 2.7 yet?
[13:15:17] <MarkusBec> harold: you can do aluminum with a 6040 priced at 1400$
[13:15:46] <norias> harold, did you see the numbers?

[13:16:04] <furrywolf> http://humboldt.craigslist.org/for/4954751402.html there is no safe or legal use of that cord. lol
[13:16:23] <MarkusBec> did they used a stepper motor to drive the spindle?
[13:16:31] <JT-Shop> nope, it cuts much smoother with less dross with 2.7 and the new planner
[13:17:47] <msantana> so the other recommendation would be the computer with linuxcnc doesn't be connected to internet, right?
[13:17:58] <MarkusBec> no
[13:18:09] <JT-Shop> no
[13:18:12] <MarkusBec> i used internet and smb shares

[13:19:36] <JT-Shop> all of my machines are on the LAN which is connected to the Internet except for the 386 one
[13:20:31] <msantana> but if I can't to upgrade anything it would not be imprudent of me, especially with regard to security updates?
[13:20:57] <msantana> s/with regard/regarding
[13:21:07] <JT-Shop> you can upgrade everything but the OS
[13:21:20] <msantana> ah, ok
[13:22:03] <msantana> just don't touch the kernel, right?
[13:22:16] <MarkusBec> yes
[13:23:05] <JT-Shop> you can set the synaptic package manager to never bother you with OS upgrades
[13:23:26] <msantana> ok, thanks for your patience :-)

http://i.imgur.com/QQKfYp5.png (40x40x10mm), with 5 holes, as you can see, all the way through. i guess the carbide would not be able to do that

[14:11:04] <harold> JT-Shop: yeah it is a pretty simple part! I care a lot about the resolution accuracy though, cannot tolerate more than 40micron inaccuracy of.. hole diam, distance between origins of the holes, etc.
[14:11:20] <harold> what's the cheapest, simplest-to-use machine you'd suggest for jobs of this nature?
[14:12:17] <JT-Shop> haas
[14:12:45] -!- akbar has quit [Remote host closed the connection]
[14:13:28] <harold> how much area does haas require? I fear these big machines may be too big. I would love to have them if logistics work out though. can a haas be put on 20th floor of a building, for example?
[14:14:00] <harold> (these considerations make me instead look to things like carbide3d... but I guess i'm starting to see some shortcomings with things like carbide3d)
[14:14:35] <JT-Shop> yea, depends on the building
[14:16:53] <JT-Shop> so 0.001" positional accuracy is not hard with a real mill
[14:17:10] <harold> carbide3d is not a real mill eh :)
[14:17:16] <JT-Shop> cheap 8020 hobby kits I don't think you will find one
[14:20:12] <JT-Shop> what kind of volume are you making?
[14:20:38] <harold> it seams the cheapest haas is like 35k, and i imagine with consumables and all it'll cost me 40k by the end of the year
[14:20:39] <archivist_herron> so many ways for a mill to be inaccurate
[14:21:04] <archivist_herron> can be cheaper to buy in
[14:21:13] <harold> I want to ideally remain under 20k i think
[14:21:16] <harold> 'buy in'?
[14:21:27] <harold> what does that mean
[14:21:33] <archivist_herron> go to a local machine shop get them to make
[14:21:35] <JT-Shop> 20k parts or 20k $
[14:22:22] <Rab> harold, what's the largest part you anticipate wanting to make?
[14:22:31] <harold> archivist_herron: don't want to buy in because we generally need parts in hours. 'buying in' would probably make it difficult to have parts in a few hours
[14:23:08] <archivist_herron> 20th floor could mean restrictions on weight and vibration
[14:23:17] <harold> Rab: less than 12x12x12 inch, can go +-5inch depending upon price and other considerations
[14:23:52] <archivist_herron> it is possible to self build for that price
[14:24:07] -!- skunkworks has quit [Remote host closed the connection]
[14:24:20] <harold> i would prefer not to self build, I probably don't have the time and the expertise i think
[14:25:10] <archivist_herron> then the haas office mill
https://www.haascnc.com/vmc_mt.asp?webID=OFFICE_MILL_VMC#gsc.tab=0
[14:25:50] <JT-Shop> carbide3d seems to be vapor ware at the moment... but you can pre-order one
[14:26:06] <harold> by the way it seems you guys here have some favorites and anti-favorites. you guys like haas, and hate tarmach, is that correct? what's the reason for this? general experience?
[14:26:08] <JT-Shop> hmm stepper driven spindle, acme screws
[14:26:43] <harold> JT-Shop: they seem to have delivered like 500 units, at this time all who put in to the kickstarter have gotten one. people who have gotten it and have written generally positively about it
[14:26:45] <JT-Shop> I just pulled haas out of the air because they make real machines
[14:26:52] <archivist_herron> we dont hate tormach, they have just used a lot of linuxcnc
[14:27:07] <Rab> JT-Shop, that's a DC spindle in NEMA form factor.
[14:27:30] <harold> use linuxcnc... in a bad way? like, being a bad oss player? using, but not contributing back to linuxcnc? that kind athing?
[14:28:18] <archivist_herron> they have contributed back in a good way
[14:28:53] <harold> so... you guys don't hate tormach. maybe I just misread some comments then
[14:29:02] <archivist_herron> tormach just developed a new lathe and needed a working control
[14:29:18] <harold> does one need to be a machinist to operate a hass? carbide3d's big pitch seems to be "as eaasy as using a 3dprinter!"
[14:29:38] <archivist_herron> it is good to have some experience
[14:30:12] -!- anth0ny_ has quit [Quit: anth0ny_]
[14:30:13] <JT-Shop> looks like a timing belt to move the X axis but they don't show that well
[14:32:49] <JT-Shop> I'm not knocking the carbide3d as it seems to be a well built hobby mill... the keyword is hobby
[14:35:08] <archivist_herron> sneaky to use carbide in its name to imply solid
[14:35:17] <JT-Shop> lol
[14:35:24] <harold> so i guess the reason i'm compelled to look to carbide3d is because it's cheap, and i keep getting the feel that the large majority of stuff i need is not that complicated. it's rare that i need a part that's like above 8x8x8in. generally it's 2x2x5in
[14:37:17] <JT-Shop> if the X and Y axis use timing belts forget about 0.001" positional accuracy
[14:37:40] <JT-Shop> harold, where are you located in the world?
[14:37:57] <archivist_herron> do not confuse resolution with accuracy
[14:38:17] <JT-Shop> yep
[14:39:51] <archivist_herron> a timing belt could be many thou out of position but be stepping in tenths of a thou, marketing hides this as much as it can
[14:41:18] <JT-Shop> then you add in belt stretch... and I know from experience as I have a belt driven plasma cutter that I made
[14:44:10] <archivist_herron> a machine can expand thermally too
[14:44:38] <archivist_herron> as to the parts, that bites you

[15:11:52] <harold> but we're quickling realizing the limitations
[15:12:07] <FinboySlick> Any of you Canadians know a good place to order 12X24X0.25 HDPE online? I'm about to order from OnlineMetals but I wouldn't mind skipping customs.
[15:12:28] <FinboySlick> It doesn't have to be hdpe mind you, anything relatively easy to machine would work.
[15:12:38] <FinboySlick> Has to be black though.
[15:12:57] <harold> we've printed with pla for a long time, but finally decided to use abs. the main reasing being that it can withstand higher temps. -- this means, parts won't "melt" when we're tapping it or making holes
[15:13:10] <MattyMatt> FinboySlick, try a kitchen supplier, colour coded chopping boards are a good cheap slab of HDPE in 6 colours
[15:13:38] <MattyMatt> half the price compared to a real plastic stockist, here in UK
[15:14:12] <FinboySlick> Yeah. I'd like flat finish on one side though, I'd have to get thicker and face on a cutting board.
[15:14:19] <harold> 3d printing in my opinion is much easier, i feel like i learned all i needed to know within 2-3 months. i think learning cnc milling will take a lot longer (depending partly on the machine of course)

[17:52:07] <zeeshan> need some help quotin a job
[17:52:24] <Tom_itx> JT-Shop did you share a folder on your linuxcnc pc so you can copy files to it?
[17:52:25] <zeeshan> http://i.imgur.com/dX9Ckn8.jpg
[17:52:28] <zeeshan> i gotta make 10 of these
[17:52:40] -!- mhaberler has quit [Quit: mhaberler]
[17:52:47] <JT-Shop> yea
[17:52:52] <Tom_itx> how/
[17:52:53] <Tom_itx> ?
[17:52:59] <zeeshan> basically drill, face, part off, then move to mill and contour that fish eye
[17:53:05] <zeeshan> how much would you charge? :P
[17:53:08] <JT-Shop> in windoze I added a right click link to each machine too
[17:53:17] <Tom_itx> yeah that's my intent
[17:53:20] <JT-Shop> what OS?
[17:53:32] <Tom_itx> so i can copy files from my cad cam right out to the shop
[17:53:38] <Tom_itx> win7 to ubuntu
[17:54:12] <JT-Shop> in ubuntu when you right click on a folder does it show sharing?

[17:55:10] <Tom_itx> lemme look
[17:55:17] <JT-Shop> ok
[17:55:23] <Tom_itx> zeeshan what diameter cup is that?
[17:55:28] <zeeshan> 3/4" OD
[17:55:30] <Tom_itx> use a holesaw
[17:55:41] <zeeshan> i can mill it quicker
[17:56:02] * Tom_itx ponders how to do it so zeeshan must change as many tools as possible
[17:56:06] <zeeshan> just wondering what i can quote
[17:56:19] <zeeshan> his buddy gave me another job which is pure welding
[17:56:26] <zeeshan> i already quoted for that, but ihavent quoted for something t his small
[17:56:28] <cpresser> Tom_itx: set up a samba share on the cnc machine. then mount that one over on your win7 machine
[17:56:31] <zeeshan> i dont wanna overquote it
[17:56:46] <Tom_itx> do you wanna eat?
[17:57:51] <zeeshan> lol
[17:57:52] <Tom_itx> setup: .5 - .75hr, mill time: 20-30 min ea i'd guess
[17:58:25] <zeeshan> setup on the lathe would be like 45 min (g-code for facing, drilling, parting)
[17:58:36] <Tom_itx> tooling: softjaws to hold it, drill, reamer, ballnose em
[17:58:54] <zeeshan> well i was gonna putt he mill in horizontal mode
[17:58:54] <Tom_itx> bottom side finished prior
[17:59:01] <zeeshan> and just do a circular arc
[17:59:06] <JT-Shop> setup on a lathe would be 30 seconds for facing, drilling, parting
[17:59:11] <Tom_itx> i bet 1.5hr by the time you're all done ea
[17:59:33] <JT-Shop> maybe less...
[17:59:43] <Tom_itx> i like to eat :D
[17:59:46] <zeeshan> $120? :-)
[17:59:58] <Tom_itx> a buck to a buck fifty
[18:00:18] <Tom_itx> machinists get paid more than grunts
[18:00:21] <JT-Shop> what material is it?
[18:00:25] <zeeshan> CR ST
[18:00:27] <zeeshan> steel

[18:00:46] <zeeshan> bungs to go from a curved spaced
[18:00:48] <zeeshan> to a flat space
[18:00:52] <JT-Shop> for a hot rod?
[18:00:56] <zeeshan> i thinkso
[18:01:01] <Tom_itx> oh hell the price just doubled
[18:01:05] <zeeshan> LOL
[18:01:13] <JT-Shop> the end use sometimes affects pricing
[18:01:22] <zeeshan> im looking at the drtawing
[18:01:26] <zeeshan> it looks like its something for a roll cage
[18:01:29] <zeeshan> for mounting something

[18:02:25] <zeeshan> its quite a bit of work
[18:02:34] <JT-Shop> aluminum?
[18:02:37] <zeeshan> yes
[18:02:48] <JT-Shop> how did you weld it?

[18:03:19] <zeeshan> and like 2 hours of machining

[18:21:32] <furrywolf> any tips on construction? I'm still trying to decide if I want to put the angle on the inside, where it's hidden and I can be sloppy, or put it on the outside, where it'll probably look nicer, but I'll need to do compound miters all around...
[18:22:09] <zeeshan> do it on the inside
[18:22:21] <zeeshan> i hate raised edges on the outside
[18:22:52] <furrywolf> that also avoids having to compound miter all the corners. :)

[20:25:10] <nema34> here i see some mistake
[20:25:17] <nema34> http://linuxcnc.org/docs/html/common/images/mill-diagram.png
[20:25:38] <nema34> what is the correct direction of the X axis?
[20:26:18] <nema34> like the arrow on the machin table, or like the arrows on the top right corner?
[20:27:12] <zeeshan> all relative to tool
[20:27:53] <Tom_itx> when i try to zero a G54 offset with the button, why would the axis try to move?
[20:28:04] <Tom_itx> seems a bit unusual behavior
[20:28:20] <zeeshan> lol
[20:28:30] <Tom_itx> running 2.7
[20:28:30] <zeeshan> that is weird :D
[20:29:13] <Rab> nema34, both. When the table moves in the direction of its arrow, the tool mills a path according to the Tool Direction arrow.
[20:29:35] <Rab> Same with the Y axis.
[20:29:43] <Tom_itx> got everything hooked back up, homed the machine just fine then i jogged to position and tried to zero the G54 offset and it tries to move the axis
[20:30:20] <zeeshan> what do you mean move axis
[20:30:24] <zeeshan> like rapid somewhere else?
[20:30:28] <Tom_itx> uh huh
[20:30:39] <Tom_itx> then it faults
[20:30:39] <zeeshan> are you sure youre not changing a tool offset
[20:30:41] <zeeshan> in the process
[20:30:44] <Tom_itx> i'm sure
[20:31:13] <Tom_itx> i will investigate more when i get a chance, no more time right now

[21:00:00] <Tom_itx> cradek i will
[21:00:15] <Tom_itx> i'm gonna test it more in a bit
[21:00:32] <Tom_itx> i brought the control & mill back in so i can bench test the whole thing
[21:01:24] <Tom_itx> i've done some major changes to the control but the limits & stepper drivers etc all stayed the same
[21:01:32] <Tom_itx> i expect a few bugs
[21:02:40] <zeeshan> yesterday night i was sleeping and in my dream
[21:02:56] <zeeshan> i was running the spindle counter clockwise, and pressed tool change button.
[21:03:01] <zeeshan> and the tool flew out
[21:03:29] <zeeshan> woke up this morning remembering the dream and i have a note now "check if tool falls out if spindle in in CCW rotation"
[21:03:35] <zeeshan> i checked it in CW rotation, but not in CCW
[21:04:15] <zeeshan> if(tc['tool_sw'] and not tc['fault'] and tc['machine_status'] and not tc['spindle_on'] and tc['spindle_speed'] <= 0.0001):
[21:04:17] <zeeshan> thats my check condition
[21:04:43] <zeeshan> i think it should be abs ( tc['spindle_speed'] <= 0.0001 )
[21:05:07] <zeeshan> cause technically if im running the spindle in reverse the speed could me -2000
[21:05:11] <zeeshan> and it'll meet my current condition!

[22:04:25] <Tom_itx> cradek here's what happened this time: I homed the machine. that was fine, i selected T21 as the first tool, jogged to position to set the X Y Z G54 offsets and the Tool offset. That was fine..
[22:04:59] <Tom_itx> then i pressed the 'Tool Touch Off' button in axis and that brought up the dialog
[22:05:20] <Tom_itx> i pressed ok to zero the tool offset and the machine started running the loaded program
[22:05:52] <Tom_itx> i'm wondering if my pendant is interferring with something because it's not functioning right now either
[22:06:09] <Tom_itx> i wasn't using the pendant for any of this

[22:14:23] <Tom_itx> ok after restarting the machine, homed it, jogged to position. all ok. Loaded the program from the default lcnc program and it started to run without pushing anything
[22:14:45] <Tom_itx> i'm gonna go thru the pendant wiring to confirm it
