Back
[00:22:09] <andypugh> As an aside, I suspect that car electric seat rails might be better than shelf sliders, as they are preloaded a bit to avoid rattles. There is no incentive to do that with shelf sliders.
[00:23:25] <MattyMatt> yeah I was too concerned with "readily available parts" at the start
[00:24:13] <andypugh> I built a Robotwars robot with jaws operated by Jaguar electric seat rails.
[00:24:50] <andypugh> andy pugh robotwars
[00:25:15] <andypugh> (wrong box, oops, was wondering if I made Google at all)
[00:25:15] <MattyMatt> mine was originally pure 19mm ply, but now I'm using found pieces of seasoned timber
[00:30:58] <MattyMatt> I was watching that year. I remember panic attack. did that win or did that spinning one beat it?
[00:31:36] <andypugh> Which year? we were in series 3-7
[00:32:14] <MattyMatt> ah, so was panic attack probably, so I can't say
[00:32:23] <MattyMatt> http://www.smidsy.net/smidsy-robot-wars-2000.html
[00:32:39] <andypugh> We nearly beat Panic Attack in the heat final once.
[00:33:38] <MattyMatt> robocup is more my cup of tea :)
[00:34:29] <andypugh> If the rules were 40 seconds immobilsed not 30, then we would have won. We were bot immobilsed but we got free in 37 seconds, they never would have, and we could have pitted them easily. The restart allowed repairs and recharge, and if that had not been the case we would have easily won the restart too. But then they were the stars (and probably rightly so)
[00:34:37] <MattyMatt> robot wars would be better if they had a biped class
[00:35:30] <MattyMatt> 11 falls or 1 submission :)
[00:36:12] <andypugh> I suspect that if they re-launched the idea now, it would be better.
[00:36:23] <MattyMatt> the key to robocup is not avoiding falling but getting up quickly. no queensbury rules in robocup
[00:36:58] <andypugh> Technology has moved on, and so have the people. I would go straight for an embedded PC (or perhaps a PIC) now.
[00:37:31] <andypugh> Just to have hardware we could control
[00:37:57] <MattyMatt> it's more entertaining with remote control
[00:38:29] <andypugh> I wasn't thinking of going autonomous (though there was an autonomous class, with no entries)
[00:39:03] <MattyMatt> too many autonomous ones would wander away. poor TV
[00:39:45] <andypugh> But we had a cobbled-together system of bought-in components to convert radio-remote into motive power, and it kept breaking and leaving us as the mercy of small-scale suppliers.
[00:41:01] <andypugh> Robot Football has shown how hard it is for robots to find cooperative other robots, let alone ones trying to hide/kill
[00:41:05] <MattyMatt> I woulda used GBA for a brain back then. toys are tough and easy to replace
[00:41:37] <MattyMatt> GBA looks like a crab. I'd like to put legs on one :)
[00:41:45] <andypugh> Interesting idea.
[00:42:48] <andypugh> We had no brain as such, just radio reciever - radio servo signal to electronic poteniometer board - golf-kart controller - motors
[00:43:14] <MattyMatt> yeah a souped up RC car
[00:43:37] <MattyMatt> killdozers in miniature :)
[00:44:26] <MattyMatt> wouldn't you feel bad if one of your ideas ended up flattening houses in palestine?
[00:44:55] <andypugh> Interstingly the robots that plugged radio control servos in, then had those twiddle physical pots did better early on. A servo twiddling a pot is remarkably noise-tolerant, as long as you get more forwards than backwards commands, you will go forwards
[00:46:21] <andypugh> I see our cnc-er in Israel has not been on for a while.
[00:47:27] <MattyMatt> yeah I've designed an interesting new type of servo, and I considered usb control but standard rc servo 20ms is fine
[00:48:17] <andypugh> For CNC or some other project?
[00:49:00] <MattyMatt> more the other way around. the servo is for robotics and one thing I want the cnc for is making the prototype
[00:49:30] <MattyMatt> I suppose I shouldn't say anything until I've had a patent check
[00:52:15] <MattyMatt> but it takes up a ribbon on a reel, using a (hopefully) novel drivechain. it's for use as a muscle emulator
[00:52:16] <andypugh> I got this spam earlier today: http://campaign.constantcontact.com/render?v=001g7xYn3eIW2PAjQMnYkM6O9J8bGRzd9IPmUhLRFiIvDa_uMzh4-NhSNHn_GtwN-BQsyHFw5B-ktjWkFSF52E0gv6rb51Y8dwsPQJ599V0Hz9GcpGkAib5DRqRFeFp41paKpqTTXYbzFAN5DKyktwjyEt5Bg5dQ_p4vX1htWpSw8QdS3bIh5FjtzxLVismVeCJC2cf2fOc_DajiXRyweKdT4glExX5Dk0A4OUmc6VnS4M%3D
[00:52:36] <andypugh> Special offer on stereolithography and RP
[00:55:42] <andypugh> I saw some lovely RP parts yesterday, a complete clean-side duct (air filter to turbo) stereolithed in water-clear plastic and polished. For airflow visualisation. £2000 it cost, and that was the in-house materials-only price.
[00:55:49] <MattyMatt> no mention of minimum order required to get the $1500 discount
[00:56:37] <andypugh> $300 miniumum, and 15% off at that level. Not a killer deal.
[00:56:55] <MattyMatt> have you seen that SL machine that uses sugar? it melts it with a hot air nozzle
[00:57:07] <andypugh> I have.
[00:57:43] <MattyMatt> that could work with powdered ABS
[00:58:57] <andypugh> I built my own RP system, a flatbed plotter, some Octave code to parse STL into slices and a vinyl cutter cutting label paper. Assembling the layers was tedious though.
[00:58:59] <MattyMatt> or acrylic, for clear
[00:59:54] <andypugh> I then had the paper prototypes cast in brass.
[01:03:49] <MattyMatt> I should get my car on the road before I start melting metal. I got stuck today because I needed a sheet of gack to protect my desktop
[01:04:33] <MattyMatt> I'm using it as my bench with the second-best top on, but I want to cut that up for the cnc
[01:07:10] <MattyMatt> and plywood has gone way up. the birch-faced stuff I made the posh top from is 50quid a sheet now
[01:07:14] <andypugh> Anyway, goodnight chaps
[01:07:22] <MattyMatt> gniggit
[01:12:09] <Valen> MattyMatt got pictures of posh bits?
[03:09:17] <tom3p> pwm in, 0 to 10v out http://www.sonelec-musique.com/images2/electronique_conv_pwm_tension_001b.gif
[03:11:14] <tom3p> or from edn http://www.edn.com/articles/pdfs/EDN/19991028/22d24311.pdf
[07:52:30] <jymm> anyone awake?
[07:57:11] <MarkusBec_away> MarkusBec_away is now known as MarkusBec
[07:59:03] <Valen> nope
[08:12:27] <jymm> ok, nevermind
[08:14:14] <Valen> lol zup?
[08:15:10] <jymm> Just wondering if anyone has any CAM utility for v-carving TTF's. Not outline, but the actual fill that could be scripted
[08:15:22] <Valen> nfi about that sorry
[08:15:29] <jymm> okey dokey
[08:15:54] <Valen> think I might make up a water cooling block for my video card though
[08:16:00] <Valen> its sitting at 80C atm
[09:02:48] <archivist> jymm, I know a commercial one
[09:03:12] <pjm> good morning
[09:03:14] <jymm> url?
[09:04:20] <archivist> http://www.vectric.com/
[09:07:37] <jymm> archivist: Thanks, those all seem to be GUI based. I'm looking for something I can script (CLI)
[09:08:17] <archivist> well you can help write one!
[09:08:37] <jymm> archivist: Oh no I can't
[09:08:56] <archivist> I have started to add that too cradek's program
[09:09:29] <jymm> archivist: ah, be sure to add tooling shape too (if you can)
[09:09:50] <archivist> and lauranceg has done something with a bit of python dunno how far he has got
[09:10:35] <archivist> yes it will have an idea of taper of the tool
[09:10:35] <jymm> archivist: It's all good. I have a GUI solution, but wanted to be able to script things if I could.
[09:11:24] <archivist> my need has gone away to an extent so its on the back burner
[09:29:18] <jymm> archivist: Eh, it's more of a nicety than anything else =)
[09:31:21] <archivist> I now know that vectric does the job in two stages, one with an endmill and the second with an engraving bit for the corners and fine lines
[09:31:44] <archivist> sat though the boring sales talk last week
[09:31:54] <jymm> lucky you
[09:32:24] <archivist> title sounded more interesting
[11:52:01] <JT-Dev> JT-Dev is now known as jt-dev
[13:07:52] <skunkworks_> http://www.youtube.com/watch?v=NFYxiyZyndA
[13:08:50] <skunkworks_> http://objects.reprap.org/wiki/Builders/EMCRepStrap
[13:35:25] <Valen1> Valen1 is now known as Valen
[15:47:36] <frallzor> is there a setting in emc that makes radiuses "larger"?
[15:47:56] <frallzor> instead of following the path now it just makes a larger radius to keep speed up
[15:48:22] <cradek> you can set a tolerance to make it follow closer
[15:48:42] <cradek> if you have big divergence you probably have an overly-low acceleration setting
[15:48:50] <cradek> tolerance mode is G64 P
[15:48:52] <frallzor> well this is extreme I'd say
[15:49:11] <cradek> what is your velocity and acceleration setting?
[15:49:31] <frallzor> hmm
[15:49:39] <frallzor> 30mm/sec for this tool
[15:50:19] <cradek> no, your axis settings
[15:50:23] <frallzor> cant really tell setting now, emc-comp in garage
[15:51:09] <frallzor> if you guessm what is the issue? =)
[15:51:12] <frallzor> *guess
[15:52:14] <archivist> expectations of the user
[15:52:18] <skunkworks_> <cradek> if you have big divergence you probably have an overly-low acceleration setting
[15:52:55] <cradek> you haven't described the "issue" you're trying to solve so I can't tell you how to solve it
[15:52:58] <frallzor> archivist yes, too much to expect a 1.5mm radius with a 3mm tool and get a 8-9mm radius =)
[15:53:02] <cradek> I'm guessing you want it to follow closer
[15:53:08] <frallzor> yep
[15:53:22] <cradek> ok, I already gave two answers then
[15:53:37] <frallzor> increase Acc it is then
[15:53:40] <cradek> not enough information to guess any more
[15:54:02] <archivist> frallzor, read the g64 docs
[15:54:42] <cradek> for machining at a certian feed you ideally would have 15-20x that much acceleration
[15:55:26] <cradek> so if you want to cut at 30mm/sec, you should probably have 600mm/sec2 acceleration
[15:56:12] <archivist> with that size cutter I would be going slow anyway
[15:56:18] <cradek> that lets you go from stop to full speed or full speed to stop in 1/20 sec
[15:56:26] <frallzor> I see
[15:57:03] <frallzor> i think full speed atm takes 1 sec from 0
[15:57:23] <cradek> it is surely just misconfigured then
[15:57:47] <frallzor> yeah
[15:58:10] <cradek> I worked on a horizontal boring mill with a table the size of a school bus, and it had a higher acceleration than that
[15:58:26] <cradek> well, maybe more like a mini van
[15:58:31] <cradek> you get the idea
[15:58:39] <frallzor> yeah =)
[15:59:50] <frallzor> another weird issue is, lets say i make a dokument that is 500mm wide that i want to mill and the board is say 700mm
[16:00:28] <frallzor> the cutter starts at 0,0 for the document, so if i place cutter 100mm in on the board it should mill in the middle of the board
[16:00:44] <frallzor> but it didnt
[16:01:07] <cradek> then you don't have your homing or offset origin or gcode right
[16:01:11] <archivist> did you touch off x and y
[16:01:22] <frallzor> i touch of xy to 0
[16:02:00] <frallzor> the numbers in emc from the code are correct and the document itself on the board has correct measurements
[16:02:16] <frallzor> but its waay of to the left
[16:02:40] <frallzor> or well, its correct from left side, but right side is wider
[16:04:20] <cradek> I don't understand what you're describing
[16:04:36] <frallzor> ill take a photo =)
[16:07:13] <frallzor> http://pici.se/p/oEHjDiQpE/
[16:07:35] <frallzor> it should be in the middle and have 130mm from each side to the milled area
[16:11:44] <archivist> you can check the span in axis
[16:12:36] <frallzor> didnt see any issues with it
[16:13:07] <frallzor> allways check before I start, starting to think its some odd issue with emc and artcam
[16:15:05] <cradek> if you want us to look for a problem in the gcode, post it somewhere
[16:15:48] <frallzor> tips for a place?
[16:16:07] <cradek> http://pastebin.ca
[16:17:23] <frallzor> http://pastebin.ca/1640370
[16:18:11] <cradek> looks extremely standard and simple
[16:18:22] <cradek> doesn't appear to mess with any offsets
[16:18:33] <frallzor> exactly
[16:18:35] <cradek> it does not load a tool length, which is odd
[16:18:48] <cradek> ok, then it's you, not your gcode :-)
[16:19:17] <frallzor> well I place the tool 130mm in, the text is about 500mm wide
[16:19:38] <frallzor> and then the right side from text to side is 230mm
[16:19:59] <frallzor> 100mm too much
[16:20:13] <frallzor> might be artcam then
[16:20:24] <cradek> after you get your offsets set how you want, jog around and look at where the cone is in the preview vs. where the tool is on the workpiece
[16:20:26] <archivist> look at the x values in the file
[16:21:21] <frallzor> hmm
[16:21:29] <frallzor> x 380mm at most
[16:21:38] <frallzor> thats not right
[16:21:52] <cradek> you can easily see the program's max and min on the AXIS screen
[16:22:17] <cradek> and the program's length
[16:22:27] <frallzor> hmm should I laught or cry now
[16:22:28] <cradek> then sit a scale on the workpiece and look at those numbers
[16:22:35] <frallzor> just saw my docu is 400mm suddenly
[16:22:44] <frallzor> isteand of 500mm
[16:22:47] <frallzor> *instead
[16:23:01] <frallzor> so the issue is pretty clear, artcam =)
[16:23:03] <cradek> that's the kind of thing you can notice by checking the preview in AXIS
[16:23:26] <frallzor> I just assumed it was ok since it was 500mm yesterday =)
[16:23:42] <frallzor> bad move =(
[16:24:30] <frallzor> at least only 1 issue to fix now then aka acceleration
[16:25:37] <frallzor> well thanks for the help =)
[16:26:00] <cradek> welcome, you'll get it
[16:26:38] <frallzor> too bad I messed this sign up, would have looked nice
[16:26:55] <cradek> cut the end off
[16:27:10] <archivist> we all have to make multiple to get one right now and again
[16:27:12] <frallzor> need it to be 760mm :/ but i would hd done it
[16:27:19] <frallzor> *have
[16:27:52] <frallzor> at least I have a configurationtesterboard now =)
[16:28:15] <frallzor> but a cherry one is a bit overkill
[16:40:46] <frallzor> tried setting a higher acc
[16:41:02] <frallzor> it acted like a machine from hell (in a good way)
[16:41:11] <tomp> tomp is now known as tom3p
[16:41:33] <frallzor> perfect radius =)
[17:59:22] <tom3p> join #cam
[18:01:29] <frallzor> the deed is done
[18:01:36] <frallzor> the perfect sign is born
[18:21:32] <cradek> yay
[18:22:28] <archivist> no pic yet :)
[18:24:27] <frallzor> the service I use crashed =(
[18:24:30] <frallzor> cant upload atm
[18:24:50] <cradek> http://imagebin.ca
[18:24:54] <frallzor> 35x higher acc worked fine
[18:24:59] <cradek> heh
[18:25:13] <cradek> that was set a little on the conservative side then!
[18:25:16] <frallzor> wonder why i didnt had it setup like that before
[18:25:31] <frallzor> ah now i remember
[18:25:43] <frallzor> someone said to type the same in feed and acc
[18:26:15] <cradek> ah, that is wrong advice
[18:26:49] <frallzor> http://imagebin.ca/view/o3uSd6R.html
[18:27:28] <frallzor> bad camera, distorts the left a bit, looks shorter than it is
[18:27:30] <frallzor> *the right
[18:28:23] <frallzor> but the result was kick-ass =)
[18:29:07] <skunkworks_> Very nice.
[18:29:35] <cradek> looks good - no burning
[18:29:41] <cradek> what's the cutting time?
[18:29:48] <frallzor> heh I finally trust my machine and put it to its limits and im selling it :P
[18:30:04] <frallzor> time... hmm 30-60 min top
[18:30:07] <dan724> hello all, I am attempting to download the ubuntu 8.04 emc2 iso and it is going quite slow. Is there a torrent or a mirrorlist?
[18:30:10] <frallzor> id say closer to 30
[18:31:10] <cradek> there was a european mirror site, but I read recently that it is down
[18:31:11] <frallzor> best damn cutters I've used with wood, and someone gave me them for free =)
[18:31:39] <cradek> yeah, there are two sites listed here: http://www.linuxcnc.org/content/view/21/4/lang,en/
[18:32:15] <dan724> the EU mirror comes up 404. The US mirror has me downloading at a blazing 15KB/s
[18:32:28] <dan724> so some time around midnight I'll finish
[18:32:41] <dan724> (my boss probably doesnt want me to stay that late
[18:33:16] <cradek> ouch
[18:33:21] <cradek> sorry, those are the only two I know of.
[18:34:06] <cradek> the one at linuxcnc.org looks slow to me right now too
[18:34:16] <dan724> ah well... I guess our CNC doesnt work until monday morning
[18:34:16] <cradek> could be me though - I'm at work.
[18:34:52] <cradek> you could download a base ubuntu 8.04 cd, and then install emc2 using the alternate install instructions. this would just take a tad more savvy on your part.
[18:35:17] <skunkworks_> That is a good idea
[18:35:24] <cradek> you can see those instructions on the same page, starting with 'If you prefer to start with the distributed Ubuntu CD'
[18:35:36] <cradek> surely they have lots of mirrors you can try
[18:35:49] <cradek> be sure you get ubuntu 8.04 hardy heron.
[18:36:05] <jymm> EU is I'm getting 117 KBs right now
[18:36:13] <jymm> I'm getting 117 KBs right now
[18:36:17] <jymm> not EU
[18:37:46] <dan724> doing that now
[18:45:04] <alex_joni> * alex_joni can try a temp mirror
[18:45:29] <jymm> alex_joni: what happened to EU mirror?
[18:46:24] <mhaberler> I'd be offering a mirror in Vienna, Austria if you guys think that makes sense
[18:49:48] <alex_joni> jymm: offline for a while
[18:50:02] <alex_joni> they upgraded the PC, and didn't migrate all data yet
[18:50:06] <jymm> alex_joni: It's online, just no files
[18:50:07] <alex_joni> mhaberler: sounds good
[18:50:09] <jymm> oh, ok
[18:51:06] <EbiDK> EbiDK is now known as EbiDK|AWAY
[18:52:55] <mhaberler> ok, give me some hints to get going. it's a 6gb/1TB raid disk oven with 100mbit/s link. give it a try and download something from http://static.mah.priv.at/public/ for a haptic experience.
[18:56:11] <mhaberler> to the poor soul trying from 99.139.73.101 - your haptic experience is severly limited by the crappy SBC global net ;-)
[18:57:31] <alex_joni> dan724: try this link: http://dsplabs.cs.upt.ro/~juve/ubuntu-8.04-desktop-emc2-aj13-i386.iso
[18:58:11] <alex_joni> mg< 1MB/sec
[18:58:19] <alex_joni> mhaberler: under 1MB / sec
[18:58:26] <alex_joni> not it jumped to 5MB
[18:58:31] <mhaberler> right, about 3-5Mbits/s
[18:58:33] <alex_joni> now 6
[18:58:38] <alex_joni> no, MByte/sec
[18:58:50] <mhaberler> I had to scale down...
[18:59:06] <alex_joni> * alex_joni is downloading "Der smaragdene Fluss"
[19:02:28] <jymm> mhaberler: Just cutious, how did you "scale down"?
[19:02:32] <jymm> curious
[19:02:55] <mhaberler> just a joke gone wrong
[19:03:19] <jymm> =)
[19:03:30] <jymm> maxed out at 1.6MB/s
[19:03:48] <jymm> avg 1MB/s
[19:04:02] <jymm> still good for a iso mirror
[19:04:48] <mhaberler> which address did you come from?

[19:08:04] <jymm> ah
[19:09:42] <jymm> alex_joni: Is this link valid http://dsplabs.cs.upt.ro/~juve/ubuntu-8.04-desktop-emc2-aj13-i386.iso
[19:10:13] <alex_joni> not anymore
[19:10:20] <alex_joni> I moved it to ~juve/emc/
[19:10:31] <jymm> alex_joni: then give me a valid link please
[19:10:34] <alex_joni> http://dsplabs.cs.upt.ro/~juve/emc/ubuntu-8.04-desktop-emc2-aj13-i386.iso
[19:10:40] <alex_joni> that was the old location
[19:11:53] <jymm> ty
[19:12:11] <jymm> Is dreamhost rate limiting?
[19:13:42] <alex_joni> no idea
[19:14:10] <alex_joni> jymm: try http://juve.ro/ubuntu-8.04-desktop-emc2-aj13-i386.iso
[19:14:13] <alex_joni> that's from dreamhost
[19:16:57] <jymm> ok, THAT link I'm getting 10MB/s
[19:17:42] <alex_joni> maybe we should add a couple mirrors
[19:17:51] <alex_joni> and let people chose
[19:18:00] <alex_joni> jymm: can you try another one?

[19:21:12] <jymm> andypugh: We're bandwidth whores, so probably not.
[19:21:28] <andypugh> I pay for 20MB cable...
[19:21:50] <jymm> andypugh: 20Mbits per second
[19:21:54] <jymm> not MB
[19:22:36] <andypugh> True, but that is still more than 365Kbytes/sec isn't it?
[19:22:45] <andypugh> (Hmm, perhaps not)

[19:23:38] <jymm> andypugh: Also, we have servers in various places too
[19:24:26] <jymm> alex_joni: Do you have access to DNS for linuxcnc.org?
[19:26:00] <alex_joni> jymm: no, but SWPadnos does
[19:26:13] <skunkworks_> cool lathe

[19:26:49] <jymm> alex_joni: ok, good to know.
[19:27:52] <alex_joni> jymm: the 1.77 seems ok to me
[19:28:01] <alex_joni> I don't pay a lot for bandwidth from there
[19:28:36] <jymm> alex_joni: I think anything sustaining ~1MBs is pretty good. Anything above that is just gravy.
[19:28:44] <alex_joni> I do like the ~150msec times to US though
[19:31:12] <jymm> alex_joni: I may be able to add a mirror, but it might be limited to 512KBs
[19:32:30] <mhaberler> well, a close friend owns that ISP - I might walk over with a bottle of good wine and return with a gigabit ethernet port without shaping..
[19:33:27] <jymm> mhaberler: If I ship you a case of wine, could i get 2U of rackspace and 100M pipe?
[19:35:03] <mhaberler> I'll ask
[19:36:01] <jymm> mhaberler: LOL! Well, I appreciate the the effort, but I wouldn't want you to abuse your friendship =)
[19:36:24] <jymm> it was more of a joke =)
[19:37:23] <mhaberler> so you guys dont believe it's a vmware image among thousands of others on a PC of the "Lucky Punch Industries" brand.. http://mah.priv.at/gallery2/main.php?g2_itemId=57046
[19:40:01] <jymm> mhaberler: Heh, the reason I said 2U is the 2nd box in that pic =)
[19:40:32] <mhaberler> that rack is so full now it wouldnt slide in a CD..
[19:40:40] <jymm> LOL
[19:41:04] <jymm> mhaberler: I have 1U in a DC now, and we have room, just no power left
[19:42:51] <jymm> mhaberler: is that 2nd the only one YOU have?
[19:43:49] <mhaberler> just the dell server and the raid case, yep - enough for me
[19:44:18] <jymm> mhaberler: OH so the raid box isn't a server too?
[19:44:46] <mhaberler> no, just 8 external sata drives
[19:44:54] <jymm> iSCSI ?
[19:45:09] <mhaberler> ok, that's getting a bit OT here.. noise reduction pleaaaaasee
[19:45:55] <jymm> Is the dell a 1920?
[19:46:06] <mhaberler> 1750
[19:46:07] <jymm> I'm trying to decide which systemto toss in
[19:46:11] <jymm> k
[19:47:11] <jymm> 1750 supports ESXi ?! i thoght only the 1900+ did
[19:49:38] <jymm> mhaberler: I am impressed with the "across the pond" link.
[19:50:11] <mhaberler> I am a retired ISP, that's why...
[19:50:59] <jymm> retired or not, connectivity across the atlantic isn't always the best.
[19:53:14] <jymm> alex_joni: Besides SWPadnos, who else has access to DNS ?
[19:54:56] <mIreland> I've got a question about setting offsets. I'm using the flat body of my main turning tool #1 for a barstop, using tool #9 to store it's offsets. When i touch off the barstop axis updates the offsets in tool #1, not #9, and I have had to edit them back into line.
[19:55:39] <mIreland> can this behaviour be fixed? what are FMS values used for, is it related to this issue?
[19:56:58] <cradek> FMS is unrelated (unused)
[19:57:11] <cradek> tool touch off updates the entry of the loaded tool as you discovered
[19:57:29] <cradek> you will need to edit the tool table manually
[19:57:45] <andypugh> You could load tool 9 first, but not actually change anything
[19:57:56] <cradek> the only other option is to use T%8 for your turret, so T9M6 actually does go to position #1
[19:58:22] <cradek> (if you are using my ladder, you do have that)
[19:58:47] <mIreland> Workaround is easy since I set tool #1 to x0z0. My drill bank will be trickier.
[19:59:41] <mIreland> Do I read that right? will a modulo trick work for four turns?(tool#3,#11,#19,#27)
[19:59:52] <cradek> sure it would
[20:00:32] <mIreland> wow i love it when number theory accidently finds a use
[20:00:47] <mIreland> Thanks i never would have dreamed that up
[20:00:57] <cradek> heh
[20:07:57] <cradek> before I had %8 in there, if I did a T9M6 the turret would lift and spin forever, never finding 9
[20:08:08] <cradek> this seems better than that
[20:10:23] <mIreland> So you are actually using the modulo operator in the prog? now i'm not sure i understand. if I call tool #27 will it find position 3 and load offsets27?
[20:10:46] <cradek> yes in the ladder
[20:11:08] <mIreland> ooo.. now i think i remember looking at that.
[20:11:11] <cradek> T27 M6 G43 will in fact turn the turret to position 27%8=3 and load offset for T27
[20:12:12] <mIreland> you rock. I'll be updating straight away.
[20:15:01] <mIreland> say radek, do you use your partoff slide? I had the pleasure of writing those Mcodes from scratch, which makes me think you dont...
[20:15:34] <cradek> no, it doesn't work, the valve thingy is broken
[20:15:46] <cradek> I just put a parting tool on the turret
[20:16:33] <mIreland> between it and the part chute this thing is fun to watch. It works by constant pressure so it's kind to tools.
[20:16:54] <cradek> heh, haven't been called by my last name since jr. high shop class. RADEK! STOP THAT!
[20:17:16] <jymm> * jymm lol @ cradek
[20:19:01] <cradek> mIreland: we need a video...
[20:19:32] <frallzor> http://pici.se/p/etLewzMQl/ I love this angle!
[20:19:42] <frallzor> full glory =)
[20:19:47] <jymm> cradek: So, it was YOU that rewired the shop drill press to 440 3ph
[20:20:22] <mIreland> trouble w partoff slide is it nips so close to the collet i need to invent a barfeed or discover a trick...
[20:21:11] <cradek> I suppose that's a feature, but yeah I depend on the work still sticking out so I can grab and move it with a hook
[20:21:25] <cradek> can't you just add a spacer?
[20:22:26] <mIreland> oh sure.. and 1/4" stock jumps out for me on collet open so it's not so bad.
[20:23:14] <andypugh> Compressed air into the spindle? Like a rudimentary pneumatic barfeeder.
[20:24:18] <mIreland> yah most likely. clever would be to vent the collet hurricane closer into the tube when it is open... there has to be some flow through that noisy sucker.
[20:24:40] <mIreland> on bigger stock i bet it would work like a charm.
[20:27:29] <andypugh> You would either need a plug or closed-ended tube longer than your longest stock, of course. But for very long stock you can push it through.
[20:28:07] <cradek> hook works well for me, but it depends on having some extra diameter you plan to cut away (otherwise you'd have to waste length)
[20:29:13] <mIreland> quite so. it's almost too tidy. there is a great bracket mount on the tail; we've been looking at all sorts of rube goldberg fixery.
[20:53:19] <mIreland> Modulo trick confirmed functional. I now have 13 well-behaved tools. one thing, tho... axis does not display the tooltips correctly for the higher order drills.
[20:54:05] <cradek> it only pays attention to the orientation and angles in the tool table
[20:54:30] <archivist> that does need expansion for other tool types and shapes
[20:57:05] <mIreland> I would like to learn more about the display of tooltips...
[20:58:17] <mIreland> Chucker manuals detailed a programming method which used paper templates for the toolholders and tools. It would be heat to emulate that.
[20:58:45] <mIreland> neat, rather
[21:09:20] <mIreland> tool#11,19,27 show as a vanilla orientation6 lathe tool, but are set as orientation 7 in .tbl file
[21:13:09] <alex_joni> did you reload the tooltable ?
[21:16:42] <mIreland> oh yes, i've gotten practised at that.
[21:22:46] <mIreland> is there a preferred way to display drills?
[21:23:17] <alex_joni> for a lathe?
[21:23:23] <alex_joni> don't think so
[21:23:28] <mIreland> yes.
[21:24:17] <mIreland> I had misinterpreted the diameter entry in a way that displayed what looked like a .5"endmill.
[21:24:46] <mIreland> that was not bad. now that i've fixed it, i broke it :)
[21:25:34] <alex_joni> ouch :/
[21:25:56] <alex_joni> * alex_joni giggles at anatidaephobia
[21:26:24] <mIreland> ana tidae?
[21:28:07] <ds3> 8
[21:28:51] <mIreland> so, where do i look to get an idea how to properly manipulate displayed shapes? I've got a use for some rectangles..
[21:31:40] <mIreland> vandammit. u made me fire off browser to learn about fear of being watched by a duck!? now i'm starting to get the fear...
[21:36:31] <mIreland> knurler and barstop could be rectangles. drills would be perfect if a point could be added.
[21:36:49] <mIreland> Ngwackquakquak!
[21:37:10] <archivist> internal circlip groove tool
[21:37:15] <archivist> :)
[21:37:35] <mIreland> yeah...
[21:38:13] <archivist> parting tool that has two radiuses and a left or right bias
[21:40:08] <mIreland> I'd love it. this machine makes mikroskopic parts and has a lot of chance for interference in tight work area. If I could render the whole stopsign and all the posts for each tool position i would do it.
[21:40:13] <archivist> actually all could be cured with user definable shapes although the offsets for some shapes are "odd"
[21:40:42] <mIreland> are there user definable shapes?
[21:40:54] <archivist> not at the moment
[21:41:31] <mIreland> boo hoo. what do they call the relevant part of the source tree?
[21:41:50] <mIreland> i've got time
[21:42:26] <archivist> hmm so have I as the job has ended...should be job hunting
[21:42:27] <MarkusBec> MarkusBec is now known as MarkusBec_away
[21:47:22] <MarkusBec_away> MarkusBec_away is now known as MarkusBec
[21:52:19] <mIreland> interesting that displayed angles update before the offsets are read by g43.
[21:54:09] <archivist> just when the offset is applied and where you need to be to be safe is fun or not
[21:54:39] <mIreland> tool #3 now displays non-existent, 11,19,27 show orient6 when there is not a 6 in the whole .tbl file...
[21:57:43] <MarkusBec> MarkusBec is now known as MarkusBec_away
[22:02:25] <mIreland> I am mystified. I padded out .tbl file with blank tools between higher order drills. no change.
[22:03:57] <alex_joni> maybe it's the wrong file?
[22:04:32] <archivist> what happens if there is a parse error
[22:05:51] <alex_joni> emc2 won't start
[22:06:04] <alex_joni> not sure what happens on reload
[22:07:47] <mIreland> if it is silent on reload, maybe i'm missing something
[22:10:58] <mIreland> file looks sound to me. it is quite simple.
[22:14:56] <MarkusBec_away> MarkusBec_away is now known as MarkusBec
[22:20:19] <mIreland> fixed. and it looks like my misuse of tool diameter is the best way to display drill. enter zeros for angles and a diameter and a roundnose drill is displayed.
[22:20:36] <mIreland> is there any practical reason not to do this?
[22:22:32] <archivist> I have to do that for a parting tool too
[22:22:43] <archivist> feels wrong
[22:23:35] <mIreland> just so long as it doesn't impact the machining somehow.
[22:25:23] <archivist> I have a parting/turning tip that I use on a normal lathe, not sure how to use on the cnc because the radius is then very wrong
[22:27:04] <mIreland> neat, maybe I can display my parting tool this way too... but I'd need to assign it to a non-existent tool position since i have a separate slide.
[22:29:42] <archivist> http://www.greenwood-tools.co.uk/ishop/728/shopscr39.html
[22:36:18] <skunkworks> this is kinda cool http://www.bridgecitytools.com/Products/Jointmaker+Pro/Jointmaker+Pro+R2
[22:36:25] <skunkworks> watch the video at the bottom
[22:40:43] <andypugh> Seems collossally expensive for what it is though.
[22:41:07] <archivist> my jaw dropped at the price too
[22:41:40] <archivist> I bet there will be a few sliced finger ends
[22:45:30] <andypugh> I can definitely see it catching on though. And being made for a 50th of the price with a 100th of the quality in CHina
[23:32:24] <MattyMatt> has anyone used a japanese saw with an ordinary mitre block?
[23:33:20] <jymm> for wood?
[23:34:17] <MattyMatt> yeah I suppose :) although my brain went immediately to a reciprocating hacksaw
[23:35:11] <jymm> Well, there's lumber, bamboo, pvc pipe, plastic tubing/sheet, etc
[23:35:27] <andypugh> There looks to be a serious bargain to be had here:

[23:36:58] <MattyMatt> I'm not building an all-electric JCB this week
[23:37:19] <andypugh> I wonder what they came off of?
[23:37:48] <archivist> a big toy
[23:38:16] <MattyMatt> they'd do nicely for a full-garage-gantry
[23:38:49] <MattyMatt> my 'friend' got a 'proper brickie' in to build a wall today. scab
[23:38:51] <andypugh> For machining garages from solid you mean?
[23:39:12] <MattyMatt> maybe machining the car from solid
[23:40:20] <andypugh> Anyway, lots of stuff to do tomorrow, then off to Wales to get muddy and wet on a motorbike.
[23:43:45] <jymm> He needs to find a girl (or two) and rethink his plans.
[23:44:24] <MattyMatt> yeah beach party
[23:44:40] <archivist> it always rains in Wales
[23:44:44] <MattyMatt> in Wales, in october :)
[23:45:05] <archivist> in mid summer too
[23:46:08] <MattyMatt> actually beach parties in N wales are quite good, I've heard
[23:46:34] <MattyMatt> what you lose in tropical weather you gain in sparse policing
[23:47:38] <MattyMatt> and that's a sexy jumper you're wearing, Blodwyn
