[00:00:00] <pfred1> styrofoam wood stuff like that
[00:01:18] <pfred1> pros are pros because they practice
[00:02:24] <joe9> pfred1: the last line is awesome. thanks.
[00:02:38] <pfred1> well a dry run never hurts
[00:03:08] <pfred1> jumping in wiht both feet only to find the pool is draind can though
[00:03:37] <joe9> quick question, What is the default directory for configs that fall under "My configurations"?
[00:04:48] <joe9> pfred1: my next steps are to 1. get a good dial test indicator., 2. practice on styrofoam and then wood.
[00:05:08] <pfred1> well depends what you plan on doing
[00:05:20] <joe9> pfred1: milling pcb's is my goal.
[00:05:28] <pfred1> if all you want to do is PCBs you could stick a flat into a T slot and put hte board up to it
[00:05:55] <pfred1> you could eyeball it
[00:06:06] <pfred1> as long as the board was oversized to begin with
[00:06:30] <pfred1> which would give you a place to hold it down BTW
[00:06:41] <joe9> makes sense. thanks.
[00:06:53] <pfred1> yeah you don't want ot run into your clamps
[00:07:00] <pfred1> that is very bad
[00:07:12] <pfred1> you could make hold downs
[00:07:33] <pfred1> all you need is a bit of metal with a hole in it
[00:07:37] <joe9> ok, will test it out with a big plywood piece that I have before putting it on an actual pcb.
[00:07:59] <joe9> ok, I can do that too. thanks.
[00:08:12] <pfred1> joe9 http://ecx.images-amazon.com/images/I/31tYHcVtloL._SL500_AA300_.jpg
[00:08:29] <pfred1> that is a hold down probably all you need even flat with a block on the other side would do you
[00:09:05] <joe9> yes, I bought them from a2zcorp.
[00:09:12] <pfred1> http://www.micro-machine-shop.com/clamping_kit.jpg
[00:09:29] <pfred1> but you don't need anything as heavy as that
[00:09:31] <joe9> that is wow.
[00:09:44] <pfred1> just so you can see the shapes
[00:10:07] * pfred1 has that kit
[00:10:42] <pfred1> see the blocks in the middle wiht the pockets milled out of them?
[00:11:02] <joe9> pfred1: yes, I do.
[00:11:19] <pfred1> you drop that on top of your work with a support block in the back of it and a thread into the pocket to your t nut
[00:11:31] <pfred1> work is held
[00:11:46] <pfred1> sec hold on
[00:12:13] <joe9> that is a good tip. thanks, will check if I can buy something like that (for a smaller size) at HF.
[00:15:16] <Jymmm> http://www.harborfreight.com/58-piece-combination-step-block-and-clamp-set-3-8-eighth-inch-16-nc-studs-1-2-half-inch-clamps-5952.html
[00:15:35] <Jymmm> http://www.harborfreight.com/42-piece-machinist-clamping-kit-90752.html
[00:17:20] <pfred1> joe9 http://i.imgur.com/havpC.jpg
[00:17:33] <pfred1> that is basically how a hold down works
[00:18:05] <pfred1> though you could just block up the back of the top piece
[00:18:07] <Jymmm> the duct tape
[00:18:17] <pfred1> you don't need that saw toothed step thing
[00:18:29] <jdhnc> I got a HF 25% coupon good for Sunday only.
[00:18:48] <pfred1> Jymmm the mill is over 20 years old the rubber is cracked
[00:19:11] <jdhnc> besides, everything needs duct tape.
[00:19:14] <Jymmm> pfred1: Lies, you know your clamping method always involves duct tape
[00:19:40] <pfred1> yeah it beats cleaning coolant off the ways
[00:19:51] <Jymmm> I got HF 20% off every other days if anyone needs em
[00:20:16] <jdhnc> they are everywhere. The 25's aren't out that often
[00:20:34] <pfred1> I get better deals shopping around
[00:20:54] <Jymmm> Yeah, and the sad thing is the only thing I need to pickup from HF is on sale for 89¢ right now.
[00:21:05] <jdhnc> http://www.harborfreight.com/r8-collet-holder-46004.html
[00:21:12] <jdhnc> what kind of collet does that hold?
[00:21:20] <pfred1> last sweet tool deal was a porter Cable 743 circular saw in the case for $15 lets see the Chinese beat that
[00:21:48] <Jymmm> I'm lovin this pot!
[00:22:13] <jdhnc> yeah man, that's some good shit.
[00:22:46] <pfred1> jdhnc I have something sort of like that but not that exact one
[00:22:56] <Jymmm> It sucks when the mfr website is lacking... http://www.stanley-pmi.com/collections/adventure
[00:22:59] <pfred1> jdhnc I could take a pic of it with the ocllets if you'd like
[00:23:11] <Jymmm> http://www.youtube.com/watch?v=Dt6xehcJpxg
[00:23:17] <pfred1> mine is a sysco?
[00:23:29] <pfred1> japanese i thnk
[00:23:35] <jdhnc> that HF collet holder?
[00:23:44] <pfred1> no the one i have it is a lot like that one
[00:24:01] <Jymmm> jdhnc: http://i124.photobucket.com/albums/p40/bdwoowoo/Blade%20Forum/007-24.jpg
[00:24:20] <Jymmm> http://i124.photobucket.com/albums/p40/bdwoowoo/Blade%20Forum/003-28.jpg
[00:24:22] <jdhnc> oh, that pot. Nevermind.
[00:25:14] <Jymmm> jdhnc: The lid also fits a ss cp and a bottle fits inside http://i895.photobucket.com/albums/ac156/ouddaammo00/KITS%20and%20GEAR/Cookware/DSCN1182.jpg
[00:25:53] <Jymmm> And you can fit a can of fuel and stove inside it too if you like http://bushcraftusa.com/gallery/files/9/2/5/6/stanley_kit01.jpg
[00:27:44] <Jymmm> The only thing is I need to figure out how/what to replace the plastic lid handle with and still maintain the same functionality
[00:28:00] <pfred1> jdhnc this is the collet set I have http://i.imgur.com/bZI8g.jpg
[00:29:04] <Jymmm> jdhnc: Melted handle http://www.youtube.com/watch?v=0fG856PmyZ4
[00:29:15] <jdhnc> cool. I need a ER-something set instead of just changing the R8 collets
[00:30:38] <pfred1> I need ER collets for an indexer I have
[00:30:54] <pfred1> my collet holder the collets are plain
[00:32:16] <pfred1> it came with a 1 1/16th collet in it but that was it
[00:33:23] <pfred1> it was a nice garage sale score for $6
[00:36:44] <jdhnc> I could get a single ER32 set with R8 & MT2 collet holders
[00:37:40] <pfred1> hmmm
[00:42:39] <pfred1> ya gotta love online package tracking
[00:42:52] <pfred1> Status: Delivered
[00:44:00] <Jymmm> Updated status: neighbor kid stole package from front door
[00:44:20] <pfred1> I was worried about that I hiked out to my mailbox and it was in there
[00:44:47] <Jymmm> hiked? How far is your mailbox?
[00:45:28] <pfred1> this is part of my driveway http://img139.imageshack.us/img139/5026/p4110020.jpg
[00:45:48] <Jymmm> looks like purrty area
[00:45:55] <pfred1> my mailbox is on the other side of that street
[00:46:12] <pfred1> so it is a bit of a walk
[00:46:46] <pfred1> but I found one of these in it so it was worth it http://www.amazon.com/Dell-nVIDIA-GeForce-Express-9JDYJ/dp/B005JZQWEO/ref=cm_cr_pr_product_top
[00:47:00] <pfred1> it is going into my dollar PC
[00:47:26] <Jymmm> no more dollar pc
[00:47:36] <pfred1> no now it is like $100 dollars
[00:47:43] <Jymmm> heh
[00:47:50] <pfred1> yeah well ...
[00:48:08] <pfred1> still almost 10 cents on the dollar
[00:48:38] <pfred1> that is my cut off for a good deal so it is still a good deal
[00:48:48] <Jymmm> =)
[00:48:54] <Jymmm> its all good
[00:49:00] <pfred1> I got a sweet PSU for it too
[00:51:23] <pfred1> Antec Basiq VP-450 450W ATX12V v2.3 Power Supply Total $33.99
[00:52:29] <Jymmm> col
[00:52:31] <Jymmm> cool
[00:52:35] <pfred1> $87 total
[00:52:51] <pfred1> as long as it plays Quake I'm happy
[00:53:23] <Jymmm> Quake? ancient game by today's standards
[00:53:36] <pfred1> I play a mod engine and game mods
[00:54:20] <pfred1> I did one last week it was so hard I had a tough time in god mode
[00:55:33] <Jymmm> oh, so you dont play online then?
[00:55:34] <pfred1> http://quakeone.com/travail/
[00:55:44] <pfred1> no just single player games
[00:55:48] <Jymmm> gotcha
[00:56:11] <pfred1> I just like shooting stuff
[00:56:21] <pfred1> and i don't always feel like going outside ot do it
[00:56:47] <Jymmm> last game I played was Diablo
[00:57:12] <pfred1> john carmak made that didn't he?
[00:57:22] <Jymmm> no idea
[00:58:22] <Jymmm> I have diablo II that's never been registered either if someone is insterested
[01:09:42] <pfred1> I need another DVI cable
[01:10:01] * Jymmm DCC's pfred1 a dvi cable
[01:10:16] <pfred1> I have a couple DVI to hdmi
[01:10:41] <pfred1> neither of the monitors i want to use has hdmi though
[01:11:24] <Jymmm> This kid is actually pretty good with the things he has done... http://www.youtube.com/watch?v=WfRovJ1KcCg&feature=related
[01:12:07] <Jymmm> pfred1: That's ok, I just got the gf a WD TV Live, it's the ONYL hdmi device in the house =)
[01:12:24] <Jymmm> ONLY
[01:13:59] <pfred1> the kid needs a lighter
[01:14:08] <pfred1> can of gas
[01:14:26] <Jymmm> No, he does real well what the firesteel
[01:14:36] <Jymmm> s/what/with/
[01:15:27] <Jymmm> pfred1: It's not easy to get a flame from an amber though. firesteel at 3000F, no problem
[01:16:50] <pfred1> he was better off with the sticks
[01:17:21] <Jymmm> on top you mean?
[01:17:35] <pfred1> he is making me hungry i have t pop my left over calzone int othe toaster oven here
[01:18:08] <pfred1> yeah when he has the pot on the sticks ehat rises
[01:18:09] <Jymmm> Heh, you should see him start primative fire, it's impressive
[01:18:29] <Jymmm> The lil bastard CAN start a fire with two sticks.
[01:18:46] <Jymmm> That shit aint easy to do
[01:18:53] <pfred1> I buy lighters by the 5 pack
[01:19:04] <pfred1> that shit *is* easy to do!
[01:19:20] <Jymmm> they dont work below 30F
[01:19:39] <pfred1> neither do I :)
[01:19:48] <Jymmm> lol
[01:20:45] <Jymmm> I'm trying to find a material that has a low autoignight temperature, but everything I've found will get the ATF on my ass
[01:21:18] <pfred1> I have some hexamine tablets
[01:21:26] <pfred1> mil surplus
[01:21:31] <Jymmm> nitrocellulose is around 90F, but unstable as hell
[01:21:53] <pfred1> I saw the mythbusters cook with C-4
[01:22:03] <Jymmm> I have soem trioxane tablets if need be
[01:22:19] <pfred1> those are for a torch aren't they?
[01:22:38] <Jymmm> No, for cooking. lil backpack stove
[01:22:42] <pfred1> oh
[01:22:51] <Jymmm> last around 15 minutes if you burn the whole bar
[01:23:15] <Jymmm> enough to boil a pot of water
[01:23:36] <pfred1> a pic of me camping out http://img694.imageshack.us/img694/8121/maineme.jpg
[01:24:04] <Jymmm> I'm trying to come up with a "tinder" that will create a flame from an amber.
[01:24:06] <pfred1> closest street light was 60 miles from there
[01:24:20] <Jymmm> pfred1: looks old, like from 70's or so
[01:24:30] <pfred1> that was 1986 I believe
[01:24:35] <Jymmm> ah
[01:24:50] <pfred1> might have been 93 I forget
[01:25:01] <pfred1> we lost the camera in 84
[01:25:06] <Jymmm> I tried for like an hour yesterday to get a flame from an amber, never really happened.
[01:25:08] <pfred1> canoe rolled
[01:25:17] <Jymmm> oooops
[01:25:17] <pfred1> ember
[01:25:22] <pfred1> amber is tree sap
[01:25:23] <Jymmm> ok ember
[01:25:47] <Jymmm> I probably could get a flame from an ember if I had amber sap =)
[01:25:56] <pfred1> the first thing you have to master is always the terminology
[01:26:04] <pfred1> see now the nest time it'll work for you
[01:26:19] <pfred1> you could make a spark with amber
[01:26:22] <Jymmm> Yeah, nest will get me flame too
[01:26:27] <pfred1> but I don't think it'd light any fires
[01:26:37] <Jymmm> you mean ember, right?
[01:26:42] <pfred1> no amber
[01:26:56] <pfred1> it was the first junk they used playing with static
[01:27:09] <Jymmm> yeah, that shit is easy to ignight.
[01:27:15] <Jymmm> ignite
[01:27:22] <pfred1> amber?
[01:27:40] <Jymmm> I want a tinder I can carry that will ignite from an ember.
[01:27:42] <pfred1> amber is actually pertified tree sap it is like a rock
[01:28:15] <pfred1> Jymmm are you one of those doomsday preppers?
[01:28:31] <Jymmm> less the doomsday part.
[01:28:51] <pfred1> the only thing worth preparing is your mind
[01:29:04] <pfred1> forget the rest of the nonsense
[01:29:18] <pfred1> because when it hits the fan there is no telling where any of it will be or you either
[01:29:29] <Jymmm> Yeah, say that when you're freezing your ass off as you have no way to start a fire.
[01:29:57] <pfred1> the best non lighter method is steel wool and a 9 volt battery
[01:30:17] <Jymmm> firesteel works
[01:30:35] <pfred1> just south of where that pic was taken is a whole beach of flint
[01:30:45] <Jymmm> heh
[01:30:54] <Jymmm> you can sell that shit seriously
[01:31:00] <pfred1> we were hanging out on it waiting for the wind to die down on the lake
[01:31:07] <Jymmm> they like that "raw" stuff
[01:31:18] <pfred1> so I grab two rocks start hitting them together guy I was with thought I was crazy
[01:31:29] <pfred1> until a spark came shooting off
[01:31:41] <pfred1> one rock was iron and quartz the other flint
[01:32:01] <pfred1> we were both high out of our minds on acid too
[01:32:08] <pfred1> it was pretty funny
[01:32:09] <Jymmm> lol
[01:32:21] <pfred1> he was lke hooke me up with a pair of those rocks
[01:32:47] <pfred1> it is all in the wrist
[01:34:04] <Jymmm> pfred1: As far as the "prepping" goes, I've seen and had things happen where I need to.
[01:34:32] <Jymmm> Last year the wall heater went out and we have an absent landlord.
[01:34:37] <pfred1> with my luck I'd have a bomb shelter and the bridge would wash out to get to it
[01:35:04] <pfred1> but I'm naturally resourceful so I'm not too worried
[01:35:07] <Jymmm> Luckily it wans't "that" cold that night, but we also have birds.
[01:35:22] <pfred1> heck 2 winters ago I lost electricity for 3 days here
[01:35:28] <pfred1> I use a heat pump for heat
[01:35:35] <pfred1> electric stove
[01:35:36] <Jymmm> and ??
[01:35:45] <pfred1> I had a bag of charcoal
[01:35:58] <pfred1> so I did a lot of barbequeing
[01:36:05] <Jymmm> and for heat?
[01:36:12] <pfred1> I put on my overalls
[01:36:19] <pfred1> it was cold
[01:36:34] <pfred1> house went down to 40
[01:36:48] <Jymmm> Well, I now have an "indoor safe" (subjective) propane heater and 300 hours of propane.
[01:37:07] <pfred1> one of those infared ones?
[01:37:14] <Jymmm> you need to crack the door/window an inch or two
[01:37:16] <Jymmm> no
[01:37:20] <Jymmm> hang on
[01:37:29] <pfred1> I have a couple of block heaters
[01:37:40] <pfred1> I wouldn't call them indoor safe though
[01:38:03] <Jymmm> pfred1: This http://www.mrheater.com/product.aspx?catid=41&id=24
[01:38:23] <pfred1> http://i.imgur.com/9v3PD.jpg
[01:38:29] <Jymmm> pfred1: and this to connect to a 20# tank http://www.northerntool.com/shop/tools/product_200362084_200362084
[01:38:32] <pfred1> it'd blow that whole tent up
[01:38:44] <pfred1> like a balloon
[01:39:06] <Jymmm> well, these ARE indoor safe without venting
[01:39:10] <pfred1> yeah that is in infared
[01:39:29] <Jymmm> it's ceramic
[01:40:23] <Jymmm> It works damn well
[01:40:24] <pfred1> it only flames when it starts then it catalyzes the fuel
[01:40:34] <pfred1> once it heats up
[01:40:52] <Jymmm> I can still see blue flame, just not much
[01:41:00] <Jymmm> it's on behind me right now
[01:42:40] <Jymmm> anyhow the point being is I have emergency portable heat now. It was one of the most difficult things for me to overcome.
[01:42:51] <pfred1> being cold?
[01:43:01] <Jymmm> as we have bird with sensative respritory systems
[01:43:05] <Jymmm> birds
[01:43:18] <Jymmm> coalmines + canaries
[01:43:27] <Jymmm> == gas detection
[01:44:12] <Jymmm> and I can use 1# disposable tanks too
[01:44:26] <pfred1> we tried to blow one of them up once
[01:44:36] <pfred1> taped a half a stick of dynamite to it
[01:44:44] <pfred1> it dented the thing just about in half
[01:44:53] <Jymmm> heh
[01:45:01] <pfred1> yeah it didn't blow up though
[01:45:26] <Jymmm> it's liquid is probably why
[01:45:30] <pfred1> I see the 20# tanks blow up in fires
[01:45:44] <Jymmm> larger are to gasify
[01:45:47] <Jymmm> area
[01:45:57] <pfred1> yeah it was under a burning pickup truck
[01:46:04] <pfred1> raised the whole truck up off the ground
[01:46:19] <pfred1> good few feet
[01:46:34] <pfred1> trick there is you have to plan
[01:46:56] <Jymmm> I have a honda EU2000i too, but to produce electric heat is wasteful
[01:46:58] <pfred1> you have to put the truck on something you can lever it up on while it is on fire so you can get the tank under it
[01:48:05] <Jymmm> Yeah, I just like the lights (pyrotechnics) not blowing shit up
[01:48:28] <pfred1> one bunch of people at that event would bring VW engine blocks
[01:48:38] <Jymmm> magnesium!!1
[01:48:45] <pfred1> they'd get a bed of coals like a foot thick then chuck one of them on it
[01:48:49] <pfred1> yeah
[01:48:55] <pfred1> man it was like a spaceship landing
[01:49:01] <Jymmm> add water for fun!
[01:49:09] <pfred1> they'd throw pots of cold water on it so it'dexplode
[01:49:12] <pfred1> yup
[01:49:31] <pfred1> they were pretty crazy
[01:50:01] <Jymmm> Yeah, like I said, I like lights, not blowing stuff up, but I'm aware of all the things out there, they kinda go hand in hand sorta.
[01:50:02] <pfred1> 50,000 drunk peole all camped out in one valley
[01:50:32] <Jymmm> one is just crude, the other an artform imo
[01:50:39] <pfred1> http://www.unadillamx.com/
[01:51:42] <Jymmm> pfred1: Hey, maybe you have an idea....
[01:51:44] <Jymmm> http://i124.photobucket.com/albums/p40/bdwoowoo/Blade%20Forum/010-15.jpg
[01:51:53] <Jymmm> http://i124.photobucket.com/albums/p40/bdwoowoo/Blade%20Forum/007-24.jpg
[01:52:00] <Jymmm> see the green handle on the lid?
[01:52:08] <pfred1> yes
[01:52:17] <Jymmm> It's plastic so you can grab the lid without burning yourself
[01:52:36] <Jymmm> It stays upright on it's own as there is a notch
[01:52:37] <pfred1> only if you like molten plastic on you
[01:53:01] <Jymmm> Right, so what do you suggest to replace it with so that it will STILL stay upright
[01:53:03] <Jymmm> ?
[01:53:24] <Jymmm> http://i124.photobucket.com/albums/p40/bdwoowoo/Blade%20Forum/003-28.jpg
[01:53:38] <pfred1> if it was me I'd say skip the plastic I'd replace it with heavy wire bent so it worked and just use a stick to lift it
[01:54:02] <pfred1> sort of like a tool box latch
[01:54:05] <Jymmm> No, I WANT the tab to stay upright, using a tool is a PITA
[01:54:18] <Jymmm> I like it, it works good.
[01:54:21] <pfred1> well if you form the wire well it would still get hot
[01:54:39] <Jymmm> right, so not metal
[01:54:55] <Jymmm> but somethign tht doens't melt either
[01:54:56] <pfred1> just use a stick
[01:54:59] <Jymmm> no
[01:55:03] <Jymmm> I dont' that,
[01:55:09] <pfred1> OK then how about ceramic?
[01:55:17] <Jymmm> I could do that all day long, that's not what I'm asking about
[01:55:23] <Jymmm> crack?
[01:55:31] <Jymmm> I'm thinking bamboo
[01:55:35] <pfred1> form it around metal wire
[01:55:59] <pfred1> so the ceramic insulator was just on top
[01:56:04] <Jymmm> It has to lay flat so you can close it all up http://i124.photobucket.com/albums/p40/bdwoowoo/Blade%20Forum/001-29.jpg
[01:56:54] <Jymmm> The issue ins't as much the material, is being able to make it stand up.
[01:57:30] <Jymmm> There is a dedicated notch in the handle to make it stay upright
[01:57:36] <pfred1> form the wire with offsets so it had some spring lock action
[01:58:09] <pfred1> it'd have to be the correct gauge wire too not bell wire
[01:58:21] <pfred1> maybe 10 gauge i don't know you'd need to measure it
[01:58:34] <pfred1> whatever the other handle wire is
[01:58:34] <Jymmm> 10ga ?! that's huge
[01:58:44] <pfred1> yeah like the wire of the other handles
[01:58:55] <pfred1> loks about 10 gauge to me
[01:59:06] <pfred1> heavier than 12
[01:59:09] <Jymmm> no no I'm thinking more like 18ga maybe
[01:59:19] <Jymmm> it's just a lide
[01:59:21] <Jymmm> lid
[01:59:39] <pfred1> but it has to fit that loop
[01:59:48] <pfred1> you can make up for it I'll draw a picture
[02:00:46] <Jymmm> I'm thinking like a clothes pin spring where both ends of the wire meet in the loop
[02:01:12] <Jymmm> they spread apart, making the wood stay up, but will spring together to lay flat
[02:02:03] <Jymmm> Kinda like a wire gate on a carabiner works
[02:02:54] <Jymmm> http://www.backcountry.com/images/items/large/MAM/MAM0080/WIGABZ.jpg
[02:03:19] <Jymmm> the holes are offset where the wire fits into
[02:04:18] <pfred1> do it neater but something like this http://i.imgur.com/5VPco.jpg
[02:05:43] <Jymmm> I'm thinking more like this, less the srping part http://3.bp.blogspot.com/-oHLjfKo9TU8/Tjr00uvI5jI/AAAAAAAAAR0/sQWxiDt1CC8/s400/Clothespin4.JPG
[02:06:00] <pfred1> maybe
[02:06:07] <Jymmm> where the spring part is, replace with wood/bamboo
[02:06:24] <pfred1> the spring alone might do the trick
[02:06:54] <Jymmm> maybe, not sure about heat though
[02:07:52] <pfred1> well I'm off to go sleep on it some late here
[02:07:58] <Jymmm> g'night
[03:00:10] <Loetmichel> mornin
[03:12:09] <Jymmm> howdy
[03:17:58] <Jymmm> Heh, first use of my pot... reheat coffee!!! YAY!
[03:21:36] <Jymmm> Loetmichel: I got one of these today http://www.youtube.com/watch?v=r2W20h15xAE&feature=related
[03:22:02] <Loetmichel> *shitshit
[03:22:07] <Jymmm> ?
[03:23:15] <Loetmichel> the plane of my wife is 45 minutes early... planned landing 11:00, eta 10:19... now ist 10:13 over here... and i have a 30 minutes drive to the airport...
[03:23:18] <Loetmichel> BRB
[03:23:28] <Jymmm> k
[04:09:18] <Loetmichel> <- at the airport... in time, plane has just landed
[04:09:31] <Jymmm> WOOHOO!
[05:12:48] <Loetmichel> re @ home
[05:45:47] <Loetmichel> ahem... gettin old: what was the gcode for milling bit radius correction? (hve to get a bearing seeat SLIGHTLY larger, about 5/100mm too small...
[05:56:29] <jthornton> you mean G41/42?
[05:58:12] <Loetmichel> *google*
[05:58:15] <Loetmichel> i think so
[05:59:08] <Loetmichel> *grrr, linuxcnc/docs is not responding :-(
[06:00:46] <Loetmichel> can anyone gice me advice how to slightly enlarge (about 3/100mm) a circle made from lines with G41/G42?
[06:02:14] <jthornton> are you already using G41/42?
[06:03:03] <jthornton> try this link http://linuxcnc.org/docview/html/gcode/gcode.html#_g41_g42_tool_radius_compensation_a_id_sec_g41_g42_a
[06:07:08] <Loetmichel> jthornton: no, i am not, never used, i compensate in the CAM beforehand.
[06:07:23] <Loetmichel> ah, linuxcnc back online, thanks
[06:09:46] <Loetmichel> so: if i write a "G41.1 D0.03" before the circle and a G40 afterwards i should get the desired effect?
[06:10:14] <Loetmichel> (assuming i am milling counter-clocwise inside the bearing seat)
[06:11:36] <jthornton> don't forget you need a move at least as large as the diameter of the cutter as a lead in move
[06:11:52] <Loetmichel> oh
[06:12:00] <Loetmichel> shi*
[06:12:22] <Loetmichel> the moves are VERY tiny 'cause the circkle is made of short lines
[06:12:53] <Loetmichel> ok, the outside is nearly done, i will try in a few minutes.
[06:13:22] <Loetmichel> if you hear something going "CLONK" over hrere something has gone wrong ;-)
[06:14:16] <Loetmichel> ahem: the moves have to be longer than den VIRTUAL diamater, not the actual, right?
[06:15:00] <jthornton> longer than the D yes
[06:15:18] <jthornton> must have enough length to move to the compensated position
[06:16:18] <Loetmichel> i.e: if i misuse the compensation to slightly enlarge the bearing seat it should work?
[06:16:47] <Loetmichel> can linuxcnc handle that small numbers for tool compensation=?
[06:18:13] <jthornton> http://linuxcnc.org/docview/html/gcode/overview.html#sub:Number
[06:20:53] <jthornton> ultimately that does depend on the precision your machine can do
[06:23:56] <Loetmichel> thx... have about 10mm to go, then i will check it
[06:25:02] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13036
[06:25:05] <Loetmichel> ;-)
[06:25:39] <Loetmichel> my machine isnt the sturdiest, so i have to cut the aluminium 0,1mm per round
[06:38:57] <Loetmichel> ... 16mm... 4mm to go...
[06:39:01] <Loetmichel> *waaaaait*
[06:46:21] <archivist> hmm bugger to find a uk supplier of grinding wheels for tool post grinder
[06:48:10] <jthornton> I wish I had a tool post grinder
[06:49:28] <archivist> I got the motor rewired today and found a vacuum drive belt and its a runner
[06:49:40] <archivist> vacuum cleaner
[06:50:11] <archivist> only takes 2" dia wheels
[06:50:15] <jthornton> for the one you picked up yesterday?
[06:50:30] <archivist> yes
[06:51:46] <archivist> its possible its part of a bigger tool as there is no rotation on its mount
[06:52:48] <archivist> unlike other dumore grinders this one has motor above the spindle
[07:12:00] <Loetmichel> jthornton: ok, G41.1 D0.03 did the trick. THANKS! -> http://www.cyrom.org/palbum/main.php?g2_itemId=13039
[07:12:53] <jthornton> nice
[07:15:12] <archivist> looks like I have to rebook to get the usb back to some sense, cant see the card reader properly
[07:15:17] <archivist> reboot
[07:36:50] <joe9> the 42 piece clamping kit is more expensive than the 58 piece clamping kit:http://www.harborfreight.com/58-piece-combination-step-block-and-clamp-set-3-8-eighth-inch-16-nc-studs-1-2-half-inch-clamps-5952.html
[07:37:01] <joe9> http://www.harborfreight.com/42-piece-machinist-clamping-kit-90752.html
[07:39:45] <joe9> the 58 piece looks like a good deal.
[07:40:03] <jthornton> the 42 is for 12mm wide T slots
[07:41:19] <joe9> i do not have 12mm wide T slots.
[07:42:28] <joe9> or, maybe i do.
[07:42:29] <jthornton> there is your sign then
[07:42:50] <joe9> just measured the taig table and the bottom wide is around 12mm and the top narrow portion is around 6 mm.
[07:42:56] <joe9> does that make sense?
[07:43:38] <jthornton> I don't know if it makes sense or not I've never owned a mini mill
[07:43:39] <jdhnc> is it 12/6, or 0.5"/0.25"
[07:44:04] <joe9> the 58 piece seems to contain everything that the 42 piece has.
[07:45:53] <jthornton> http://littlemachineshop.com/products/product_view.php?view=classic&ProductID=2718
[07:46:13] <jdhnc> the 58 has 3/8" studs
[07:46:23] <jthornton> the 58 piece set is bigger than your mill
[07:47:09] <joe9> oh, ok. thanks. guys.
[07:47:28] <jthornton> np
[07:47:54] <archivist> jthornton, took some pics of the dumore http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_04_07_Dumore/
[07:49:31] <jthornton> ah a flat belt, cleaned up nicely...
[07:49:47] <archivist> was black
[07:50:45] <jthornton> so that one only does the OD?
[07:51:35] <archivist> I think so unless there were extensions available
[07:52:11] <jthornton> nice knurling tool, looks like a monkey wrench
[07:52:42] <archivist> has what looks like freehand punching for pats pend
[07:52:58] <jthornton> just looking at that now
[07:53:21] <archivist> small production or prototype
[07:53:25] <jthornton> straight and angled wheels too
[07:53:27] <joe9> i bought these: https://www.a2zcorp.us/store/ProductDetailNP.asp?Cguid={42C55481-747E-4B3B-B8A3-BEDF711D92AF}&ProductID=5966 https://www.a2zcorp.us/store/ProductDetailNP.asp?Cguid={42C55481-747E-4B3B-B8A3-BEDF711D92AF}&ProductID=6016 https://www.a2zcorp.us/store/ProductDetailNP.asp?Cguid={42C55481-747E-4B3B-B8A3-BEDF711D92AF}&ProductID=5836
[07:53:44] <joe9> do you think that will be good enough for my clamping needs to hold down a pcb?
[07:53:50] <joe9> or, would I need more?
[07:54:34] <jthornton> for pcb you just need double sided tape as I understand it
[07:55:25] <joe9> jthornton: ok, thanks. I was thinking of clamping it down instead of taping it. but, if that is the only option, then that is what I will go for.
[07:55:26] * jthornton wanders out to the shop
[07:55:50] <jthornton> well you could make a vacuum table...
[07:56:30] <joe9> jthornton: that is out of my league, at this point.
[07:56:40] <joe9> and with drill holes that will not fly.
[07:56:56] <jthornton> of course the best advice will come from someone that has ACTUALLY done a pcb so that's not me
[07:57:44] <Loetmichel> *HA* Fits like a glove! Now i have to make the connection bar and a coupling for the stepper, then continune with X axis -> http://www.cyrom.org/palbum/main.php?g2_itemId=13042
[07:58:08] <Loetmichel> making a CNC mill out of Trash/ebay isnt THAT simple... ;-)
[08:11:17] <archivist> depends on the supply of trash
[08:15:48] <JT-Shop> lol
[08:50:57] <Loetmichel> archivist: some pieces of Linear rail and stuff a coworker has aquired over the years and now i have to build a CNC out of it
[08:54:03] <Loetmichel> because i promised it to him ... ("i'll se waht i can do")
[09:00:08] <archivist> hmm small ball screw fleabay 330712651213
[09:02:33] <Tom_itx> is is used up?
[09:35:32] <ReadError> i wish a2z had a better site
[10:07:56] <joe9> the mobil vactra #2 oil smells like castor oil.
[10:10:56] <jdhnc> a2z site blows, as do their emails
[10:11:43] <jdhnc> but, so does Mesa's :)
[10:16:13] <joe9> now, that I can move the axes with my keyboard. the next step is to move it with a program. Any suggestions on how I can start doing that? i am reading through the manual. there does not seem to be something geared towards that.
[10:16:55] <archivist> er!
[10:17:20] <archivist> teh samples not good enough?
[10:17:41] <ReadError> joe9: run that EMC default path?
[10:18:10] <joe9> archivist: no, i did not check the samples. let me check them. thanks.
[10:18:16] <joe9> ReadError: what do you mean?
[10:18:27] <ReadError> when you first start the app
[10:18:56] <ReadError> it has that default linux cnc path
[10:18:58] <archivist> ReadError, far too obvious!
[10:19:11] <ReadError> sorry ive never done it
[10:19:14] <ReadError> still n00b
[10:19:26] * pfred1 is n00b 4 life!
[10:19:43] <archivist> ReadError, but you worked it out!
[10:19:55] <archivist> cannot be a noob
[10:20:40] <ReadError> well i had to cheap my esxi instance ;)
[10:20:43] <ReadError> check*
[10:20:47] <ReadError> i knew it had something
[10:22:10] <pfred1> what'd it have?
[10:22:28] * pfred1 has a new Simpson 260
[10:31:59] <ReadError> it has a default Linux EMC path
[10:32:02] <pfred1> man it is in some tough shape
[10:35:43] <archivist> simpson multimeter?
[10:36:17] <pfred1> yes
[10:36:39] <pfred1> I need to refurbish it it is rough
[10:37:49] <pfred1> furry inside http://i.imgur.com/r5W20.jpg
[10:38:13] <archivist> hmm could find a better one
[10:38:26] <pfred1> I have 2 better ones it'll be fine when I'm done with it
[10:39:02] <pfred1> the meter itself looks OK
[10:39:19] <pfred1> really I'd rather get them like this this means it sat and didn't get used
[10:41:40] <pfred1> archivist what do you want for $3?
[10:42:13] <archivist> rust :)
[10:42:23] <pfred1> well it has that
[10:42:35] <pfred1> heck even the bakelite is oxidized
[10:42:46] <pfred1> but it should polish up
[10:43:11] <pfred1> for $3 there was no way I was leaving it
[10:43:14] <archivist> I owe £3 for the tool post grinder I got a couple of days ago, I think they would want more now its a bit cleaner
[10:44:12] <pfred1> refurbishing meters is a hobby of mine http://i.imgur.com/8dalX.jpg
[10:45:21] <archivist> one of mine is manuals for electronics test gear so help out where possible
[10:45:53] <archivist> http://www.collection.archivist.info/searchv13.php?searchstr=Simpson
[11:00:11] <joe9> why do we use the stepconf limit of 1000 to -1000 for X and Y axis? Why not the actual taig values?
[11:01:08] <pfred1> you cna use whatever you like
[11:02:58] <pfred1> 1000 is a nice round number though
[11:17:32] <JT-Shop> joe9, depends on how you set up your machine
[11:41:43] <DJ9DJ> namd
[11:41:50] <DJ9DJ> good evening
[11:43:56] <joe9> is there some good material to learn about coordinate systems, other than this: http://linuxcnc.org/docs/html/gcode/coordinates.html
[11:46:33] <JT-Shop> I think that is it other than the G code descriptions
[11:47:37] <joe9> JT-Shop: i read about the machinist's manual by Peter Simd (I think).
[11:47:51] <joe9> Do you think that is a good read to help me get to use the machine better?
[11:48:04] <joe9> or, am I better off just sticking with the linuxcnc manual?
[11:48:33] <joe9> i feel that reading the "GCode Overview" before the "Coordinate Systems" chapter helps.
[11:48:39] <joe9> for me.
[11:58:08] <joe9> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Understanding_G-Code there are just a few lines here. Is G-code really that simple
[11:59:02] <asdfasd> almost :D
[11:59:49] <cradek> that page smells of good intentions
[12:08:02] <archivist> gcode is a bit risc like :(
[12:17:14] <Dave911> In it's basic form Gcode is pretty simple. Add looping and conditional stuff and it can get more complex.
[12:40:27] <alex4nder> hey
[12:54:08] <ReadError> joe9: you have the machinery handbook?
[13:13:46] <pfred1> I got the latency test to run on my dual core
[13:16:22] <ReadError> one of those centering bits is like required right?
[13:17:19] <alex4nder> centering bits?
[13:17:24] <alex4nder> you mean like, a wiggler?
[13:17:55] <pfred1> a center finder
[13:19:16] <pfred1> hey look you're all famous on the Internet now http://i.imgur.com/ccbNl.jpg
[13:19:36] <alex4nder> yes
[13:19:37] <alex4nder> like a wiggler
[13:19:46] * pfred1 likes jigglers ...
[13:19:50] <alex4nder> haha
[13:20:25] <pfred1> man this box ain't bad
[13:21:05] <pfred1> it is steady like a rock at 11531 it only spiked to that for a sec when I opened firefox too
[13:21:25] <alex4nder> ReadError: when you get your mill, buy all of these products http://www.fishermachine.com/
[13:21:37] <alex4nder> Fisher's stuff is great
[13:21:48] <alex4nder> and the products are small enough to be useful on the Taig
[13:22:36] <alex4nder> joe9: you too
[13:22:39] * pfred1 would just like to officially say ATI sucks!
[13:25:32] <pfred1> glxgears didn't even phase my latency :)
[13:28:39] <jdhnc> my biggest latency hits were PATA writes
[13:28:57] <pfred1> jdhnc I'll try hdparm -tT
[13:30:01] <pfred1> it budged it a smidgen I reset it now it is sitting at 9955
[13:30:20] <alex4nder> nice
[13:30:28] <pfred1> yeah I'm tickled
[13:30:46] <pfred1> this is just on the live CD
[13:31:18] <pfred1> I think I'm going to have to rename this box the rock
[13:31:31] <alex4nder> what's the lowest latency anyone has seen from a current RTAI setup on a PC?
[13:31:44] <pfred1> there is a page on the wiki
[13:32:29] <alex4nder> yah, but that info is all ancient
[13:32:45] <pfred1> this is going to break it
[13:32:52] * pfred1 is going to run hwinfo
[13:33:04] <pfred1> oh that hurt!
[13:33:23] <pfred1> put that into the howto for box abuse
[13:33:31] <jdhnc> my atom was less tgan 10m for hours with just a few glxgears
[13:33:36] <pfred1> it spiked it to 32609
[13:33:45] <pfred1> yeah run hwinfo
[13:34:19] <jdhnc> 10k... androud kb sucks
[13:34:37] <jdhnc> Ill try that when I get home
[13:34:48] <pfred1> what that command is is automated computer abuse
[13:35:08] <pfred1> aptitude install hwinfo;hwinfo
[13:35:20] <joe9> cat /proc/interrupts
[13:35:32] <joe9> check what is responsible for the interrupts too.
[13:36:20] <pfred1> good way to whack out someone's CNC machine setup a cron job to run hwinfo
[13:36:49] <pfred1> I don't know where the latency is coming from!
[13:37:32] <joe9> for me, a disk access was killing latency.
[13:37:55] <joe9> and that was the pata_amd drivers.
[13:38:36] <pfred1> I think i could safely call this box 12000ns even though hwinfo did spike it to 36312
[13:39:05] <pfred1> hwinfo does some bad black magic voodoo when it runs
[13:41:11] * pfred1 likes to do a hwinfo > MySystem.txt redirect on his machines
[13:42:34] <WillenCMD> hey everybody
[13:42:55] <pfred1> hey
[13:43:01] <alex4nder> pfred1: yah.. mmaping /dev/mem is probably not the smartest thing to do in an RT environment.
[13:43:16] <djdelorie> anyone know how to get these screws out? http://www.delorie.com/photos/southbend-lathe/img_2631.html
[13:43:18] <pfred1> alex4nder yeah i just did it again whatever it is it happens early on
[13:43:32] <WillenCMD> so now that we have gladevp with linux 2.5, is it possible to create a custom standalone screen, not incorporated into axis or touchy?
[13:43:36] <pfred1> only spiked to 25167 this time
[13:44:29] <Thadius> hello
[13:44:33] <pfred1> hi
[13:44:48] * pfred1 is starting to feel like a hello bot ....
[13:44:54] <Thadius> was looking for some help involving config installs for linuxcnc
[13:45:31] <pfred1> joe9 I wish there was an app that said what caused timing spikes
[13:46:05] <Thadius> if anyone is available, if not, understandable :)
[13:46:26] <Cylly> pfred1: yesterday: no, the calipers were from "aldi" and yes, 10 eur. and no, the dont loose the count when switched off
[13:46:36] <Cylly> oh, ups
[13:46:39] <Loetmichel> re @ home
[13:46:48] <pfred1> Loetmichel then they're the better ones
[13:47:14] <archivist> Thadius, in irc just ask the real question
[13:47:20] <pfred1> maybe the really cheap ones i got are broken
[13:47:44] <pfred1> Loetmichel I saw in other pictures you have the silver and teh black calipers
[13:47:51] <Thadius> thank you, I try to be considerate of ongoing conversations
[13:47:54] <Loetmichel> yeah, me "endmaße" (precision ground metal blocs to a specific length) say the thre i have are accurate to 0,02mm
[13:48:05] <pfred1> Thadius this is IRC just type
[13:48:13] <archivist> Thadius, all are generally interleaved
[13:48:52] <Loetmichel> s/me/my
[13:49:11] <pfred1> Loetmichel I liked that cable chain thing you made
[13:49:22] <Thadius> installed 10.04 w/linuxcnc, i've downloaded my configs for probo's v90, and can not seem to find where to save my config files to, in order for it to show up in linuxcnc
[13:49:25] <Loetmichel> pfred1: which one?
[13:49:36] <Loetmichel> the white or the yellow?
[13:49:37] <pfred1> Loetmichel they all looked good to me
[13:49:59] <Thadius> all paths and directories appear different on forums and tutorials than what I'm seeing
[13:50:15] <pfred1> Thadius did you install to your hard disk?
[13:50:23] <Loetmichel> was short on money but had enough 1,5mm FR4 handy... and some copper studs ;-)
[13:50:28] <Thadius> yes i did Pfred1
[13:50:46] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=4381
[13:50:47] <pfred1> Thadius OK just checking hard to save with the live CD
[13:51:06] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=4384
[13:51:10] <Thadius> of course, gotta cover the basics, i understand
[13:51:14] <Loetmichel> was working great ;-)
[13:52:32] <pfred1> that spiked my latency installing the plugins
[13:54:40] <Thadius> when i open up Linuxcnc, there's a path listing "/usr/local/ect/linuxcnc/config" however i have nothing past "ect" on my system
[13:55:12] <pfred1> Thadius type locate linuxcnc
[13:55:24] <Thadius> ok
[13:55:28] <pfred1> well maybe locate linuxcnc | grep config
[13:55:49] <pfred1> the first one might be a little scrolly
[13:55:56] <Thadius> in terminal?
[13:56:00] <pfred1> yes
[13:56:01] <Thadius> sorry, new to linux as well
[13:56:03] <Thadius> ok
[13:56:42] * pfred1 hopes Thadius's db is updated ...
[13:56:53] <pfred1> sudo updatedb
[13:57:10] <pfred1> refreshes slocate
[13:57:48] <pfred1> Linux keeps making me feel like I'm new to it
[13:57:56] <Thadius> i have not updated anything
[13:58:12] <Thadius> linux box isnt connected to interent currently
[13:58:13] <pfred1> yeah run sudo updatedb then run the locate command
[13:58:20] <pfred1> it is a local thing
[13:58:25] <Thadius> ok
[13:58:30] <cradek> you're mistaken about the spelling of "etc"
[13:58:38] <pfred1> that would do it
[14:00:43] <Thadius> upon using "locate" all paths appear to be /usr/share/doc/linuxcnc/examples/sample-config
[14:01:38] <pfred1> time for some brute force searching find / -name "*.ini" | grep linux
[14:02:24] <pfred1> Thadius what version of linuxcnc did yo usay you had?
[14:03:34] <Thadius> i actually do not know my version, i downloaded the 10.04 linuxcnc iso and installed from disk
[14:03:43] <jdhnc> with glxgears, firefox, some other stuff, hwinfo spked it to 12.9k
[14:03:58] <pfred1> jdhnc really good
[14:04:02] <joe9> pfred1: check out the tracing of the linux kernel.
[14:04:14] <joe9> it is pretty helpful to find out what caused the latency.
[14:04:42] <pfred1> the video on this page can give me latency http://www.cyrom.org/palbum/main.php?g2_itemId=4384
[14:04:45] <jdhnc> pfred1: I guess, doesn't matter so much since I have a Mesa card doing stepgens
[14:06:23] <pfred1> jdhnc my P3 does 18400 do this box isn't much better than that
[14:07:29] <Thadius> ok, found it, ver 2.5 linuxcnc
[14:08:25] <pfred1> jdhnc I wanted to make sure you weren't running an older emc2 one
[14:08:41] <Thadius> gotya
[14:08:54] <pfred1> that would change the directory names if you were
[14:10:35] <pfred1> Thadius have you made a configuration file yet?
[14:11:14] <Thadius> i have not, i installed ubuntu 10.04 with linuxcnc, found my v90 config files, and was trying to figure out where to extract them to
[14:11:23] <Jymmm> What's a thermally non-conductive material that doesn't burn/melt?
[14:11:27] <pfred1> yeah the system can't find it if it doesn't exist yet
[14:11:41] <pfred1> Jymmm carbon?
[14:11:47] <Thadius> sound logic 0_o lol
[14:11:58] <Jymmm> pfred1: thermal non-conductive?
[14:12:06] <pfred1> Thadius run stepconf it'll generate config files for you
[14:12:17] <pfred1> Jymmm carbon doesn't conduct heat very well
[14:12:26] <Jymmm> Really?
[14:12:32] <Thadius> Linuxcnc Stepconf Wizard?
[14:12:39] <pfred1> Thadius yes
[14:12:57] <pfred1> then you'll be able to find them
[14:13:03] <pfred1> make them an easy to find name
[14:13:17] <Thadius> i have a file named v90.stepconf, is that relevant to starting off?
[14:13:59] <pfred1> I don't know you need to run scripts/stepconf I think it is on the menu
[14:14:12] <Thadius> ok
[14:14:30] <pfred1> when it asks you for a machine file name think of something you'll spot
[14:14:32] <Thadius> sorry about the mess, gotta crawl before I walk
[14:16:56] <pfred1> Thadius I have a local build of linuxcnc so it isn't exactly like the CD
[14:16:58] <Thadius> ok, i found the v90 stepconfig file, and chose modify existing upon running the Stepconfig wizard. making a lil more sense now
[14:17:33] <pfred1> will it let you save it as a new file?
[14:17:44] <ReadError> oh nice Thadius
[14:17:47] <ReadError> you got the fireball?
[14:18:07] <pfred1> ReadError that sounds painful to me
[14:18:20] <ReadError> ;o
[14:18:41] <ReadError> i need me a nice pendant
[14:18:41] * pfred1 played too much MUD back in the day ...
[14:18:42] <Thadius> well, not yet REaderror
[14:18:55] <ReadError> any off the shelf solution thats good and reasonably priced ?
[14:19:00] <ReadError> Thadius: i was looking at one
[14:19:05] <ReadError> you ordered it already?
[14:19:12] <Thadius> i'm making sure i can design, produce gcode, and get linuxcnc up and running before my purchase
[14:19:21] <ReadError> i like the comet, but dont want all the jibbajabba that comes with it like PC
[14:19:25] <ReadError> monitor
[14:19:29] <ReadError> already have enough of that stuff
[14:19:34] <pfred1> Thadius what are you planning on making?
[14:20:21] <ReadError> is it capable of cutting aluminum if you go slow you think?
[14:20:34] <Thadius> plastic case for project flashlight designed with wind-turbine technicians in mind
[14:20:58] <pfred1> then you're going to need CAD software for that
[14:21:17] <ReadError> i thought gcode makes itself?
[14:21:24] <Thadius> i have my CAD/CAM solutions, designed and produced gcode
[14:21:24] <pfred1> not really
[14:21:27] <ReadError> when you convert the cad to it
[14:21:30] <alex4nder> haha
[14:21:38] <alex4nder> welcome to the [g-code] thunderdome, bitch
[14:21:38] <ReadError> well you have to do the toolpath and such
[14:21:53] <Thadius> i'm at the "Control" part of my mis-adventures
[14:21:53] <ReadError> fortunately my background consist of software engineering
[14:22:18] <pfred1> ReadError then write us some good CAM software
[14:22:28] <alex4nder> ReadError: you should learn about CAM before you try to mill something
[14:22:32] <alex4nder> you're going to be really disappointed.
[14:22:33] <ReadError> pfred1: UNfortunately i work full time
[14:22:38] <ReadError> and starting school in the fall
[14:22:55] <Thadius> quit work, eat ramen, design awesome software, get paid, give us free
[14:22:58] <Thadius> win win right there
[14:23:02] <ReadError> lol
[14:23:03] <pfred1> because right now that is where the chain is really broken
[14:23:15] <ReadError> CAD is hard ;(
[14:23:19] <alex4nder> CAM is harder.
[14:23:27] <Thadius> ok, question time
[14:23:28] <pfred1> cad is but at least you can kind of do it
[14:23:37] <ReadError> alex4nder: eagle is pretty simple
[14:23:41] <ReadError> ive done it in the past
[14:23:44] <ReadError> only toner transfers
[14:23:55] <alex4nder> ReadError: easy CAM is easy
[14:23:57] <Thadius> HALui, any advantages adding when running Stepconfig?
[14:24:04] <alex4nder> just whack into the material in a grid
[14:24:05] <alex4nder> done
[14:24:11] <pfred1> I think there is a translator for blender
[14:24:16] <alex4nder> but its slow, and the results suck
[14:24:47] <pfred1> http://www.thingiverse.com/thing:6236
[14:25:14] <alex4nder> anyone own a copy of cambam?
[14:25:26] <Thadius> should I "Include Halui user interface component"?
[14:26:43] <Thadius> wait, Hal = button and pin placements on screen for, oh say something like e-stop, run pause ect ect?
[14:27:12] <Thadius> brb
[14:27:18] * Loetmichel was buing groceries today... Wife approved a little "treat" for me.... the next weeks i will eat more healthy "sweets" ;-) -> http://www.cyrom.org/palbum/main.php?g2_itemId=13045
[14:27:21] <pfred1> doesn't HAL stand for Hardware Abstraction Layer?
[14:28:24] <alex4nder> Loetmichel: that's awesome
[14:28:41] <Loetmichel> yes, and tasty
[14:28:57] <micges> pfred1: yes
[14:29:06] <Loetmichel> and surprisingly cheap... only about 60 eur for 6.5kg
[14:29:13] <pfred1> micges sounds very abstract ...
[14:29:16] <Loetmichel> 65
[14:29:21] <Loetmichel> eur
[14:29:48] <alex4nder> Loetmichel: it's ham season here.. but they're far more 'corporate' looking
[14:29:59] <micges> pfred1: no, it's quite nice
[14:30:02] <Loetmichel> its spanish
[14:30:16] <alex4nder> bbl
[14:30:35] <Loetmichel> they are the only ones who let the foot stay on as i just learned ;-)
[14:33:39] <pfred1> wow there is an inkscape gcode generator?
[14:34:08] <pfred1> what is next MS-Paint?
[14:34:42] <ReadError> i want the PC copy of machinery handbook
[14:34:47] <ReadError> but cant find it ;(
[14:35:00] <pfred1> ReadError looked on pirate bay ?
[14:36:30] <pfred1> http://www.google.com/url?q=http://www.industrialpress.com/ext/StaticPages/Handbook/MH28Demo/MH28/Handbook.pdf&sa=U&ei=z5SAT530HvKP0QGj27CBCA&ved=0CAQQFjAA&client=internal-uds-cse&usg=AFQjCNFM7m7yt46AG8w2_Zra7SiQJagVsg
[14:37:02] <Thadius> ok, back
[14:38:13] <ReadError> pfred1
[14:38:15] <pfred1> don't search for filetype:torrent "machinery handbook" unless you're into really kinky stuff ...
[14:38:16] <ReadError> I got the actual book
[14:38:23] <ReadError> they have a PC version
[14:38:29] <ReadError> that does the calculations and such
[14:39:26] <pfred1> isn't there a script that does some calculating in linuxcnc?
[14:41:11] <Thadius> guys, thanks for your help, looks like i got the stepconfig done for v90
[14:41:23] <pfred1> Thadius now you have a file to find
[14:42:13] <Thadius> ya, working on that part :)
[14:42:36] <pfred1> where the heck are the extra scrips in the install CD?
[14:43:31] <pfred1> oh they're right in /usr/bin
[14:44:46] <Thadius> ok, seems when i modified the v90stepconfig file, it created my v90 folder and everything in the place i was initially looking for
[14:44:57] <pfred1> Thadius the next time you're in Linux in a console for laughs hit tab twice at a command prompt and hit Y
[14:45:31] <Thadius> i'll save that for the next computer i build with ubuntu :P
[14:45:34] <Thadius> :)
[14:45:51] <pfred1> it just did it it doesn't hurt naything
[14:46:00] <pfred1> Display all 2643 possibilities? (y or n)
[14:46:05] <Thadius> i'm confused enough as is
[14:46:09] <Thadius> lol
[14:46:16] <pfred1> those are all the executables on your path
[14:46:40] <pfred1> it is the tab completion hack in the shell
[14:47:03] <Thadius> ok, so in the .zip i downloaded from probotix, they had a v90 folder and a v90stepconfig file.....it looks like after i ran the v90stepconfig file, it created everything that was already in the v90 folder on the zip..
[14:47:37] <Thadius> so, stop me if i'm wrong.... the v90 folder was essentially the offspring of running the stepconfig file?
[14:47:46] <pfred1> whoah what is this freaky program? latencyplot
[14:48:58] <pfred1> it needs a help button I've no idea what any of it means
[14:51:33] <pfred1> now it won't go away
[14:53:01] <pfred1> check it out http://i.imgur.com/1Yh5h.jpg
[14:53:49] <pfred1> Thadius stepconf can create or edit config files for linuxcnc
[14:54:09] <pfred1> it is a wizard
[14:56:05] <pfred1> see that is what i don't like about Ubuntu Tasks: 202 total
[14:56:11] <pfred1> that is off the wall
[14:57:48] <micges> pfred1: install 'bum' and disable useless services, next manage startup programs system->preferences->startu programs
[14:57:59] <micges> it will decrease to about 160
[14:58:01] <pfred1> micges bum?
[14:58:10] <micges> boot up manager
[14:58:18] <micges> type it in synaptic
[14:58:26] <pfred1> my custom debian build runs X with 38 procs
[14:59:14] <micges> we will happly use your ubuntu builds with 38 tasks :)
[14:59:51] <micges> but seriously amount of tasks have no impact on realtime part of rtai kernel
[15:00:17] <Thadius> can linuxcnc simulate machine operation before install?
[15:00:48] <pfred1> I don't see why I couldn't hook my machine up to this box running the live CD
[15:01:00] <Thadius> i guess i should google first then ask
[15:01:22] <micges> Thadius: what do you want to simulate?
[15:01:42] <pfred1> bbiab calzone talking to me
[15:01:50] <Thadius> just a few projects i have gcode for
[15:02:13] <Thadius> didnt know if i actually needed machine connections first or if linuxcnc could simulate
[15:02:18] <micges> Thadius: you have sim configration directory, sleect from them sim_mm.ini and run it
[15:02:46] <micges> there are many simulated machine configs just for things like that
[15:03:21] <Thadius> well i was hoping to use the configs i have for my "future" machine
[15:03:22] <micges> did you run Configration picker ?
[15:03:43] <Thadius> i just got stepconfig done for the machine i'm getting, thats all so far
[15:04:17] <Thadius> have linuxcnc opened up with my v90 configs, staring at the screen and the "test" LinuxCNC" code thats on it
[15:04:50] <micges> if you have lpt on this pc I don't see problem
[15:11:07] * pfred1 wonders if he can't embed xeyes into the taskbar ....
[15:15:29] <pfred1> this is the funniest bug report I've ever read http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=579185
[15:17:33] <Thadius> ok, stoked like whoa
[15:17:37] <Thadius> its actually running :)
[15:17:42] <Thadius> thank you for all the help
[15:17:52] <pfred1> Thadius glad you're hapopy
[15:18:01] <pfred1> happy even
[15:18:27] * pfred1 is happy today too
[15:18:49] <pfred1> I didn't get my DVI cable like i wanted but I got a few others things besides
[15:19:18] <gene77> does anyone know what the leadscrew pitch on a mini-lathe is?
[15:19:56] <pfred1> can't put an indicator on it and turn it say 10 times?
[15:20:48] <gene77> done that, wear errors are driving me batty.
[15:22:34] <gene77> scale, accrding to my figures ought to be 51200, but between uneven backlash etc, its difficult to confirm
[15:29:38] <pfred1> yeah you have to discount backlash
[15:29:57] <pfred1> I was just doing it on my mill looks like ever crank is a tenth of an inch on it
[15:30:56] <pfred1> there was someone here that used to talk about how they error mapped their lead screws but I've no idea how they did it
[15:32:12] <pfred1> I want one! http://www.youtube.com/watch?v=mxxdq6y8z8M
[15:37:11] <mrsun> what a beast =)
[15:37:30] <pfred1> mrsun it reminds me of the T-1 from T-2?
[15:38:59] <kb8wmc> is anyone running the Temperature Control Circuit developed by Anders Wallin to run under LinuxCNC? http://www.anderswallin.net/2010/11/temperature-control-circuits/
[15:39:01] <pfred1> gene77 it looks like the developer's handbook covers compensation and error correction
[15:40:50] <gene77> I have read that a couple-4 times. But I think if I want sub 10 thou accuracy on Z, its going to take a ball screw.
[15:42:18] <pfred1> gene77 what kind of machine do you have?
[15:42:35] <gene77> Right now, 10 taps at .1 each are about .001 short of an inch. Unforch there is not only backlash, there is some rubber between the screw and the carriage that I've not ID'd the src of. Yet..
[15:43:12] <gene77> A Speedway branded mini-lathe, very poorly finished IMO.
[15:44:03] <pfred1> for that kind of accuracy you might want to look into a cylindrical grinder or something
[15:45:07] <djdelorie> step config all changed, max speeds now X=180 Y=560 Z=60 IPM, but still under 0.5 thou resolution
[15:45:09] <gene77> I did have the motor laying on the table, doing 50 IPM, but hooked up here, and the driver ratio set to 8 from the 16 it was, I am still getting error stop before I get to 30 ipm.
[15:46:24] <pfred1> djdelorie you got your drivers 0.0005 ?
[15:46:51] <djdelorie> the controller boards have always supported better resolution than that (not physical precision, just steps)
[15:47:07] <djdelorie> but I had the simulated steps/rot too high, linuxcnc couldn't send steps that fast
[15:47:18] <gene77> It runs that lathe-pawn routine pretty well though. I wish stepconfig would run on this box, but it seems it cannot talk to this parport, broken pipe messages galore.
[15:47:31] <djdelorie> so as per advice here, I reduced the steps/rot as much as I could without going about 0.5 thou per step
[15:47:32] <pfred1> djdelorie you realize to get that precision you're up for a 5 digit bill for linears right?
[15:47:47] <djdelorie> pfred: mathematical precision, not physical precision
[15:48:08] <Jymmm> pfred1: Nah, just a lil extra duct tape and oyu can get 10 digit precision
[15:48:15] <pfred1> djdelorie the nI have ot ask what is your target goal
[15:48:18] <gene77> Yup, running at 8 steps, I am going to need a damper, its noisy as hell at about 1.95 ipm
[15:48:32] <djdelorie> there's an upper limit on steps/rot where linuxcnc just can't send steps fast enough, and a lower limit where the motors can't go fast enough to keep up with linuxcnc
[15:48:55] <djdelorie> 0.5 thou is within that range, so I just picked a steps/rot that put me in the 0.1 o 0.5 thou range
[15:49:30] <Jymmm> djdelorie: mid-band compensation is typical built into most (quality) stepper drivers.
[15:49:43] <djdelorie> Jymm: not a stepper driver
[15:49:45] <Jymmm> Geckos, OEM750's, etc
[15:49:46] <pfred1> yeah resonance is a big issue
[15:49:57] <pfred1> bldc don't resonate?
[15:49:57] <gene77> I've done that on my mill too, these acme's aren't micrometer material :)
[15:50:13] <djdelorie> it's a servo motor, yes it resonates, that took a while to dampen as much as I could without losing accuracy
[15:50:21] <Jymmm> djdelorie: ah
[15:50:32] <pfred1> well there are physical dampers too and they will run different under load
[15:50:53] <pfred1> sorts like apple run different :)
[15:51:04] <djdelorie> so anyway, linuxcnc can now command the motors right up to their max RPM
[15:51:15] <pfred1> sounds like progress
[15:51:18] <djdelorie> max Y jog is scary, the whole machine shakes back and forth
[15:51:30] <pfred1> djdelorie I got my dual core to latency test
[15:51:38] <pfred1> djdelorie heh
[15:51:39] <djdelorie> now I just need to single-step this video of the drill test to see if the bit is vibrating...
[15:52:03] <pfred1> yeah your motor setup is pretty powerful
[15:53:18] <pfred1> djdelorie you ever checked out the shopbot style machines?
[15:53:34] <djdelorie> I've looked at way too many machines...
[15:54:12] <djdelorie> yeah, looks like the carriage is shaking when the drill "hits", need to put in a controlled jog
[15:55:03] <djdelorie> axis is still putting a weird symbol way off in space for my drill test job, nothing I've done has made it go away. Instead of a 0.6" square "work area", it's 30.6 by 27.6
[15:55:56] <djdelorie> or a dwell time?
[15:56:15] <pfred1> linuxcnc has accelerate and decellerate
[15:56:30] <pfred1> I mean you got to take inertia into account
[15:57:06] <djdelorie> maybe I need to crank the acc/dec settings way down instead?
[15:57:17] <pfred1> can't hurt to try
[15:57:23] <djdelorie> my motors can acc/dec WAY faster than my plywood table can accomodate :-)
[15:57:34] <pfred1> yes so yo uneed to compensate
[15:57:35] <djdelorie> dwell is in PICOSECONDS? wow.
[15:57:55] <pfred1> linuxcnc means business
[15:58:00] <djdelorie> back to the shop... biab
[16:03:42] <DJ9DJ> gn8
[16:09:45] <Jymmm> I thought silicon wasn't suppose to burn?
[16:35:57] <alex4nder> ok
[16:41:13] <joe9> if I go to the end of the axis, do I end up destroying the "lead screws"?
[16:42:34] <micges> no if you have bumpers and/or limit switches
[16:44:22] <joe9> i do not have limit/home switches yet.
[16:44:27] <alex4nder> just don't do it
[16:44:28] <joe9> but, I am thinking about having them.
[16:44:40] <joe9> yesterday, i went too far off my z
[16:44:49] <alex4nder> yah, I remember
[16:44:58] <joe9> and I had to push it up to get the taig z-axis to work.
[16:45:29] <joe9> today, a few times, I was at the end of the axis, and the axis wouldn't turn but make a noise as if it was bumping against something.
[16:45:47] <joe9> http://ganoksin.com/blog/aule/2009/08/11/home-is-where-the-taig-is/
[16:45:50] <alex4nder> did it sound like wurrerrrerrrerrrerrr
[16:45:54] <joe9> yes.
[16:45:58] <alex4nder> your stepper stalled
[16:46:02] <joe9> yes.
[16:46:07] <joe9> i think the stepper stalled.
[16:46:28] <joe9> not sure if doing that many times is a bad idea or if the steppers are designed for it.
[16:46:36] <alex4nder> they're not supposed to do that
[16:46:48] <alex4nder> where was the table/spindle when it stalled?
[16:47:34] <joe9> at the end of the axis. i do not rememeber if the stepper stalled or if it was trying to move but as the axis was at the end, could not move further.
[16:47:54] <joe9> it was like bumping against something.
[16:48:00] <alex4nder> it probably was
[16:48:22] <alex4nder> which axis was it?
[16:48:26] <joe9> when something like that happens, it probably affects the lead screws.
[16:48:34] <joe9> alex4nder: i did that on all 3 axis.
[16:48:38] <joe9> x,y and z.
[16:48:47] <joe9> on Z, when you are all the way at the top
[16:48:52] <joe9> and it cannot go any further.
[16:48:56] <joe9> you get that noise.
[16:49:24] <joe9> on, X-axis, you go all the way to the other direction from where the stepper is
[16:49:34] <joe9> alex4nder: does that make sense?
[16:49:41] <alex4nder> joe9: yah, I don't understand what the problem is
[16:49:52] <alex4nder> it's like if you were asking me why you stall your car when you drive it against a wall
[16:50:04] <alex4nder> it's pretty clear right. ;D
[16:50:20] <joe9> alex4nder: no, I understand why it stops. I want to know how bad it is for the machinery when that happens.
[16:50:31] <alex4nder> the stronger the stepper the worse it is
[16:50:33] <joe9> Would I have messed up something pretty bad.
[16:50:35] <alex4nder> no
[16:50:36] <alex4nder> you're fine
[16:50:47] <joe9> oh, ok. thanks, that is what I was looking for.
[16:51:29] <alex4nder> when you get your measuring gear, you can obsess over backlash
[16:51:42] <joe9> I want to set up the limits of my taig to the actual values instead of the 1000 to -1000 that I have. For the taig, X is 12", y=5.5", Z =6inches.
[16:52:07] <joe9> does that go to MIN_LIMIT and MAX_LIMIT of the AXIS_x of the _.ini file?
[16:52:31] <jdhnc> easier to just set it in stepconf
[16:53:02] <cradek> joe9: yes
[16:53:29] <cradek> joe9: first consider where you will home it. normally Z homes at the top of travel, so MAX is 0 and MIN will be -6
[16:53:53] <joe9> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?MillSetup is what I am trying to do.
[16:53:54] <cradek> this is because you want to be able to home, no matter what's attached to the table.
[16:54:21] <cradek> for XY, home can be wherever. if you have no switches, mark it with a sharpie or something.
[16:54:42] <joe9> the article has it at 0,0,-7.8 in his case.
[16:55:06] <joe9> mine will be 0,0,-6 inches for the MIN_LIMIT for X,Y and Z respectively.
[16:55:22] <cradek> sounds fine
[16:55:39] <joe9> cradek, thanks.
[16:55:48] <cradek> so you'll move X,Y to their low limits to home them
[16:56:01] <joe9> yes.
[16:56:23] <joe9> but, I want to add home switches as here http://ganoksin.com/blog/aule/2009/08/11/home-is-where-the-taig-is/
[16:56:58] <joe9> i think it is good to have home switches, so that I will not get lost while tool changing, etc.
[16:58:03] <joe9> that is the first thing I want to add to my taig. I already have limit switches, but, I am not using them. I should start using them, by positioning them properly.
[16:58:22] <cradek> you can home to limit switches. you don't need more switches if you have the limits.
[17:01:35] <joe9> ok, cool. I will position the limit switches and they will work as home switches too.
[17:02:18] <joe9> cradek: i think it is a good idea
[17:02:42] <joe9> to learn the details/attributes of the .ini file instead of relying on the stepconf.
[17:02:59] <joe9> cradek: do you think it is? or, is it not worth it?
[17:08:11] <joe9> what is the units of the MIN_LIMIT or MAX_LIMIT values? the LINEAR_UNITS = mm and SCALE = 400.0
[17:08:54] <joe9> is it just plain "mm"?
[17:09:43] <joe9> but, that might not make sense as I can seem to move the X-axis more than the 12 inches (as noted in the Specification)
[17:12:53] <joe9> cradek, any thoughts, please?
[17:25:53] <joe9> anyone used this: CNC: Programming The Modern CNC Mill I and II with Heinz Putz DVD
[17:25:58] <joe9> like it or worth it?
[17:30:26] <ReadError> link to torrent? ;)
[17:30:41] <alex4nder> haha
[17:31:10] <ReadError> nah but for real, if you get it hook up a copy ;)
[17:31:50] <joe9> alex4nder: what do you think of this: http://www.youtube.com/watch?v=OO3GAyyHiA8
[17:35:21] <joe9> alex4nder: i am surprised that you do not have limit or home switches. Why not? they seem pretty useful, from what I read.
[17:35:22] <ReadError> http://www.youtube.com/watch?v=lAGpnWG8UDA&feature=relmfu
[17:35:24] <ReadError> lol
[17:35:37] <ReadError> he sleeps like 6" from his CNC
[17:38:15] <alex4nder> joe9: from my experience so far, homing and limits have been the least of my worries.
[17:38:48] <joe9> how do you home it to an exact spot for changing tool bits?
[17:39:03] <joe9> at the exact spot, isn't that hard?
[17:39:06] <alex4nder> homing doesn't help you with changing bits
[17:39:16] <alex4nder> you need a touch off for that.
[17:39:48] <alex4nder> homing gets your machine in sync with the software for X Y and Z
[17:39:53] <alex4nder> but that's spindle Z, not tool Z
[17:41:52] <alex4nder> the "hard" part is touching off on your work.
[17:42:27] <joe9> http://www.deepgroove1.com/settingupsoftlimits.htm
[17:42:35] <ReadError> awww shucks
[17:42:42] <ReadError> they had links to those dvds
[17:42:49] <ReadError> but all the sites went retrieve-only ;(
[17:42:56] <ReadError> after the feds took down megaupload
[17:43:08] <joe9> alex4nder: i read from http://ganoksin.com/blog/aule/2009/08/11/home-is-where-the-taig-is/ that he is using the switches instead of touching off.
[17:43:09] <ReadError> and no love on usenet ;(
[17:44:04] <joe9> alex4nder: "touching off" on the work seems a lot harder process than setting up the switches.
[17:44:54] <alex4nder> the switches don't make touching off easier
[17:45:11] <alex4nder> unless your machine loses track of where it is, becasue your steppers stalled.
[17:45:22] <alex4nder> which shouldn't be happening.
[18:04:55] <jdhnc> I found it easier to learn the details of the ini/hal/etc after getting everything working and scaled correcly via stepconf. That way the numbers made sense. My current install is no longer stepconf-able anyway.
[18:59:04] <JT-Shop> joe9, you still have to touch off on the work piece even if you have home switches
[19:01:52] <asdfasd> is there somewhere example how to add touch off button but only for Z axis?
[19:02:29] <JT-Shop> instead of selecting the Z axis and using the normal touch off button?
[19:03:08] <asdfasd> yes, the selected axis is the last I move, and I keep zeroing wrong axis
[19:03:39] <JT-Shop> do you have halui loaded and what version are you running?
[19:04:14] <asdfasd> Im new, I just have fresh instalation, the latest version
[19:04:24] <JT-Shop> which version?
[19:04:40] <asdfasd> 2.4.7
[19:04:48] <jdhnc> almost latest
[19:04:52] <JT-Shop> ok, that is not the latest version
[19:05:06] <jdhnc> touch off with Z-end
[19:05:23] <JT-Shop> do you know where the Show Hal Configuration is on the Axis menu?
[19:05:46] <asdfasd> wow, there is a new version I just noticed it
[19:06:04] <JT-Shop> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?UpdatingTo2.5
[19:06:06] <asdfasd> yes I know it
[19:06:15] <jdhnc> 2.5 fixes that oddity with my atom p-port
[19:06:28] <JT-Shop> open up show hal and in the pins see if halui is loaded
[19:07:49] <JT-Shop> and you may not need that...
[19:08:45] <Thadius> does anyone have a good link to read up on gcode, interested in how you manually edit, like say, adding tool change, ect ect
[19:09:56] <JT-Shop> Tn M6 G43 works for me for tool change
[19:10:08] <Tom_itx> http://linuxcnc.org/docs/html/gcode.html
[19:10:15] <Thadius> thanks
[19:10:28] <JT-Shop> and http://linuxcnc.org/docview/html/gcode/tool_compensation.html
[19:11:02] <asdfasd> there is no halui
[19:11:19] <Tom_itx> JT-Shop, where did the RS274NGC_33a.html move to?
[19:11:44] <JT-Shop> asdfasd, http://linuxcnc.org/docview/html/config/ini_config.html#_hal_section_a_id_sub_hal_section_a
[19:11:52] <JT-Shop> Tom_itx, what is that?
[19:12:04] <Tom_itx> gcode reference i believe
[19:12:15] <JT-Shop> the quick reference?
[19:12:31] <JT-Shop> http://linuxcnc.org/docview/html/gcode.html
[19:12:32] <Tom_itx> http://www.linuxcnc.org/handbook/RS274NGC_3/RS274NGC_33a.html
[19:12:37] <Tom_itx> that's where it used to be
[19:13:19] <JT-Shop> I don't recall that document at all
[19:13:30] <JT-Shop> must be very old
[19:13:53] <JT-Shop> this one? http://linuxcnc.org/docview/html/gcode/rs274ngc.html
[19:13:55] <ReadError> cant you just use one of those centering things
[19:14:02] <ReadError> and get it lined up on a point of origin
[19:14:02] <asdfasd> now halui loaded
[19:14:22] <Thadius> i love when you tell someone what you're doing, ie...cnc work, and they get all excited and say "oh really?!! I could do that, you should show me whats involved" and then watch as the wind leaves their sails :)
[19:14:42] <Thadius> as you try to explain to them the process
[19:14:54] <JT-Shop> asdfasd, you can put MDI commands in the INI anc call them with a pyvcp button http://linuxcnc.org/docview/html/config/ini_config.html#_halui_section_a_id_sub_halui_section_a
[19:14:55] <Tom_itx> JT-Shop looks ike it
[19:15:13] <ReadError> Thadius: i need a good tutorial ;(
[19:15:16] <JT-Shop> which one LOL
[19:15:18] <ReadError> i got the mill ordered
[19:15:23] <ReadError> about to order the motors
[19:15:29] <ReadError> but have never done anything in cad yet ;((
[19:15:38] <Tom_itx> JT-Shop, err no, that's not the complete one i don't think
[19:15:46] <JT-Shop> you don't need cad
[19:15:58] <JT-Shop> Tom_itx, that's it afaik
[19:16:10] <Tom_itx> the other one listed the memory offsets for G54 etc
[19:16:18] <JT-Shop> some trimming and reordering has gone on since 2.4
[19:16:26] <JT-Shop> oh wait
[19:17:00] <ReadError> jepler
[19:17:02] <ReadError> er
[19:17:05] <JT-Shop> they have been combined to one place http://linuxcnc.org/docview/html/gcode/overview.html
[19:17:10] <ReadError> JT-Shop: i need something to mock up my parts dont I/
[19:17:10] <Thadius> ReadError, i havent found one all encompassing piece of internet gold for learning what little i have, took/takes a lot of work
[19:17:42] <JT-Shop> ReadError, well it depends on the parts really
[19:17:59] <ReadError> JT-Shop: mostly "routing" work
[19:18:02] <ReadError> nothing too 3d intensive
[19:18:08] <ReadError> cutting CF parts and such
[19:18:18] <ReadError> same depth
[19:18:33] <Tom_itx> JT-Shop, so 5221 would be the G54 offset for x?
[19:18:35] <JT-Shop> you can use qcad to draw that out then
[19:18:44] <Tom_itx> 5222 - Y
[19:18:45] <Tom_itx> etc
[19:19:14] <Tom_itx> does that apply to most standard fanuc controls?
[19:19:18] <JT-Shop> they are in order (X Y Z A B C U V W)
[19:19:48] <Tom_itx> so if you call up the 5221 address it will hold the G54 X offset value
[19:20:20] <JT-Shop> yep #5221 is G54 X
[19:21:03] <djdelorie> ok, two drill bits later, lessons learned: 30 IPS is too fast a drill feed, not because of the drill, but because the carriage wobbles, and 50 thou is not enough clearance for XY travel
[19:21:08] <djdelorie> http://www.delorie.com/photos/cnc/drilltest-cnc-015.html
[19:21:18] <JT-Shop> Tom_itx, I guess you might have to ask on the fanuc channel that question lol
[19:21:27] <djdelorie> also, backlash compensation is needed. Top: no compensation, bottom: with 30 thou compensation
[19:21:46] <Tom_itx> JT-Shop, well we had some controls you had to enter the offset that way
[19:21:51] <Tom_itx> or at least edit it
[19:22:01] <Tom_itx> i think you could have the G54 in the code
[19:22:06] <JT-Shop> 30IPS = 1800IPM yea that is fast
[19:22:13] <djdelorie> sorry, 30 IPM
[19:22:14] <Tom_itx> but you set the memory location from the machine coordinate system
[19:22:27] <djdelorie> why are there two standards for specifying feed rates? :-P
[19:22:36] <JT-Shop> 30 IPM is pretty fast for drilling anything but butter
[19:22:49] <Tom_itx> or air after the bit breaks
[19:22:52] <JT-Shop> Tom_itx, sounds confusing
[19:22:59] <JT-Shop> yea
[19:23:03] <djdelorie> I got 130 holes before it snapped :-)
[19:23:43] <JT-Shop> maybe you wore the bit out
[19:23:53] <djdelorie> could be
[19:24:16] <djdelorie> is there a way to pick up a gcode program in the middle, if you have to stop, change bits, and back up a few missed holes?
[19:24:43] <JT-Shop> run from line in Axis
[19:25:17] <djdelorie> ah, in the Machine menu. Thanks
[19:25:43] <djdelorie> I tend to hit stop or estop when I need to pause it, too, that will help :-)
[19:25:47] <JT-Shop> yep or right click I think
[19:26:01] <JT-Shop> http://linuxcnc.org/docview/html/gui/axis.html#_menu_items
[19:26:03] <djdelorie> yep, that too
[19:26:40] <djdelorie> is there a signal in hal connected to "program running" ? I know about the charge pump signal, is that what I want, or is that just "machine on" and not "run" ?
[19:27:02] <JT-Shop> asdfasd, you can add a pyvcp button on the right side
[19:27:29] <JT-Shop> or you would have to change the code for Axis
[19:28:05] <JT-Shop> djdelorie, http://linuxcnc.org/docview/html/man/man1/halui.1.html
[19:28:37] <djdelorie> halui.program.is-running is probably it
[19:33:47] <asdfasd> JT-Shop can you read personal messages?
[19:34:19] <JT-Shop> yes
[19:34:57] <JT-Shop> djdelorie, open up Show Hal and put the pins your interested in a watch window to see what the behavior is
[19:35:12] <asdfasd> I sent you personal but no answer
[19:35:56] <JT-Shop> I replied in here as it is better to discuss linuxcnc on this channel
[19:37:18] <JT-Shop> someone other than myself may have a better answer
[19:37:36] <asdfasd> Im sorry too many people I though better not to mess with other questions
[19:38:45] <asdfasd> I found /usr/bin/axis it looks like here is programmed the function of touch off button, but I cant see where is created the button
[19:40:09] <asdfasd> vars.current_axis.get()
[19:40:28] <jdhnc> work offset question. I have two gcode files for a part, one engraves with a v cutter, one cuts out with an end mill. I want to make 5 sets of these by doing all the engraving, then changing tools and doing all the cutouts. Any good references or sample code?
[19:41:09] <Tom_itx> offest?
[19:41:20] <Tom_itx> G54 for one operation and G55 for the next
[19:41:21] <JT-Shop> asdfasd, I'm not quafied to talk about the inner workings of axis.py
[19:41:55] <Tom_itx> jdhnc, or is that just a tool offset?
[19:41:57] <JT-Shop> jdhnc, sample code to do what?
[19:41:57] <Tom_itx> change..
[19:42:25] <jdhnc> JT: do multiple cuts of the same code, offset by N inches
[19:43:54] <Tom_itx> set it up as a macro?
[19:44:03] <JT-Shop> jdhnc, you can set your tool lenght for tool 1 cut then set the tool lengh offset for tool 2 then cut
[19:44:25] <Tom_itx> i'm not sure i get what you're after
[19:44:27] <JT-Shop> or just just G54 for one tool and G55 for the second
[19:44:34] <JT-Shop> nor am I
[19:45:00] <Tom_itx> i think he want's to engrave 5 sets then do the cutouts
[19:45:09] <Tom_itx> set the cuts up as a macro
[19:45:18] <Tom_itx> offset whatever x or y number you need
[19:45:31] <Tom_itx> i've not done macros but that sounds reasonable
[19:45:39] <jdhnc> I have one file that engrave, one that cuts (change tool between runs). I want to be able to run the first one (to engrave) 5 times, offset by N inches, then go back and run the one that cuts out 5 times.
[19:46:18] <Tom_itx> maybe someone can step you thru setting up a macro with an x y offset
[19:46:26] <Tom_itx> that would do it
[19:46:31] <Tom_itx> one for each tool
[19:46:50] <Tom_itx> err subroutine i mean
[19:47:23] <Tom_itx> what offset do you need?
[19:47:38] <jdhnc> probably just x + 1.5
[19:48:10] <Tom_itx> like i said, i haven't done subroutines simply because i have a cad cam package and do it there but that would do it
[19:48:37] <Tom_itx> set your cuts up in the sub and call it with the x y values incrementing them as you loop x times
[19:48:44] <Tom_itx> (5) in your case
[19:48:59] * jdhnc reads some more.
[19:49:30] <Tom_itx> see if there's a subroutine example
[19:50:54] <Tom_itx> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?SubroutineSample
[19:51:00] <Tom_itx> jdhnc ^^
[19:51:03] <Tom_itx> maybe
[19:51:28] <Tom_itx> naw that's not that good of an example
[19:51:36] <jdhnc> I can do subroutines, I am just somewhat confused about changing fixture offsets in code.
[19:52:17] <Tom_itx> if you just want a different fixture offset change the G54 to G55 G56 etc
[19:52:25] <Tom_itx> and enter their values in the offset table
[19:52:46] <Tom_itx> then call them when needed
[19:53:17] <Tom_itx> that's common for doing multiple steps on a part with say 2 vises or fixtures
[19:54:19] <Tom_itx> with the sub, you wouldn't need that
[19:54:35] <Tom_itx> just loop 5 times and enter a new X offset each time
[19:56:17] <JT-Shop> or use a G92 offset, I do that on my plasma
[19:56:27] <Tom_itx> jdhnc, have a look at this: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Oword#Sample_5_Subroutine_for_generating_multiple_parts_using_Local_and_Global_coordinates
[19:56:45] <JT-Shop> yea Tom_itx to the rescue
[19:57:20] <Tom_itx> i just copy the part in my cad package before i post the gcode :)
[19:57:35] <Tom_itx> and sort the tools the way i want them
[19:57:37] <jdhnc> that looks perfect, thanks.
[19:57:55] <jdhnc> mine makes me do each toolpath by hand
[19:58:02] <jdhnc> or at least, semi-by-hand.
[19:58:10] <Tom_itx> sometimes that's kinda handy
[19:58:48] <Tom_itx> subs make for shorter program files
[20:24:02] <djdelorie> JT-Shop: is-running wasn't it. It doesn't activate when homing or jogging
[20:24:41] <djdelorie> Background: my controllers can't quite keep the motors dead-on-target, I'm looking for a signal to tell them it's ok to let the motors drift a little because the machine is not doing anything at the moment
[20:24:42] <JT-Shop> no, I think it is only on when a program is running
[20:25:16] <JT-Shop> hmmm
[20:25:21] <djdelorie> current, I hook estop. I was going to hook machine-on instead, but I figured if there was something that automatically shut off the motor drive when the program ended, that would be better
[20:25:42] <JT-Shop> servo?
[20:25:46] <djdelorie> yup
[20:26:13] <djdelorie> they can track their location even when the drive power is off, and restore position when needed
[20:26:25] <JT-Shop> machine power should turn the amps off
[20:26:40] <djdelorie> yeah, I know about that one. But the machine doesn't "shut off" when the program ends
[20:26:45] <djdelorie> or does it?
[20:27:24] <JT-Shop> no the machine power is still on at the end of a program
[20:27:45] <djdelorie> I couldn't find a pin that meant "I'm jogging" either
[20:27:56] <JT-Shop> halui.machine.off bit in
[20:27:56] <JT-Shop> pin for setting machine Off
[20:28:29] <djdelorie> that would be really annoying, having to keep turning the machine on all the time ;-)
[20:28:36] <JT-Shop> must be a big problem to go to all this trouble
[20:28:54] <djdelorie> no, just annoying. The motors make a subtle buzzing sound when they should be idle
[20:29:12] <JT-Shop> maybe your not don't tuning them
[20:29:14] <djdelorie> yes, I know, "fix the pid loop" but the encoder position is quantized
[20:29:29] <djdelorie> it's buzzing between 0 and +1 for example
[20:29:56] <JT-Shop> are you talking about the DRO reading?
[20:30:11] <djdelorie> I've got them tuned as best as my software allows - the controllers have their own "dro" console
[20:33:50] * JT-Shop heads inside
[20:33:51] <djdelorie> hmmm... perhaps a filtered version of motion.current-vel ?
[20:33:56] <JT-Shop> good luck
[20:54:53] <asdfasd> what that mean in properties/permisions
[20:55:07] <asdfasd> you are not the owner you cannot change these settings
[20:55:14] <asdfasd> Im logged as administrator
[20:55:51] <Jymmm> O_o
[21:02:40] <jdhnc> so, g92 seems very confusing.
[21:03:06] <djdelorie> asdfasd: did you mean "root" ?
[21:03:13] <djdelorie> there's no "administrator" in Linux
[21:05:11] <asdfasd> in users and groups settings is shown as administrator
[21:05:18] <asdfasd> probably mean root
[21:05:41] <asdfasd> actually I want to edin one read only file
[21:06:00] <asdfasd> I just tried that: sudo chmod 666 file.odt
[21:06:05] <djdelorie> there's a good chance, the right thing to do is copy the file to a local directory, and edit the copy
[21:06:29] <asdfasd> I edit the copy but I cant copy over the original
[21:06:36] <djdelorie> what's the file?
[21:06:50] <djdelorie> odt is a spreadsheet, but who's spreadsheet is it?
[21:06:54] <asdfasd> axis.tcl
[21:07:13] <asdfasd> this is the actual file
[21:07:38] <djdelorie> I don't know if that's an overridable file, so what you probably want is "sudo vi axis.tcl" (or some other editor, like emacs or gedit)
[21:08:01] <djdelorie> it's bad practice to leave a system file writable by everyone; that's how virii get in
[21:08:47] <asdfasd> ops
[21:08:49] <asdfasd> I made it
[21:08:58] <asdfasd> now is 666
[21:09:09] <asdfasd> but I dont know the previous permisions
[21:09:39] <asdfasd> how to return the previous permisions after I finish
[21:09:48] <djdelorie> what were they?
[21:10:13] <djdelorie> probably 644
[21:10:38] <alex4nder> OK
[21:10:45] <alex4nder> the inside of the concrete mold has been sealed
[21:10:48] <alex4nder> tomorrow I pour
[21:11:22] <Tom_itx> http://ss64.com/bash/chmod.html
[21:14:57] <Thadius> just curious, anyone have any links to their works handy?
[21:15:36] <alex4nder> like, the m achines running, or things they've made?
[21:16:23] <Thadius> both actually :)
[21:16:53] <alex4nder> http://www.andern.org/alexander/taig_milling_wood.m4v <- that's the one I show everybody
[21:16:53] <ReadError> lets see some videos and work alex4nder:)
[21:17:01] <alex4nder> http://www.andern.org/alexander/taig.m4v
[21:17:04] <alex4nder> and that's the setup
[21:17:07] <djdelorie> Thadius: my results for today so far: http://www.delorie.com/photos/cnc/drilltest-cnc-015.html
[21:17:15] <ReadError> i seen those 2
[21:17:29] <djdelorie> (bottom includes backlash compensation)
[21:17:55] <ReadError> are they supposed to be even?
[21:18:01] <alex4nder> djdelorie: is that some random copper plate?
[21:18:12] <djdelorie> it's a blank PCB
[21:18:14] <alex4nder> ah
[21:18:21] <djdelorie> I was testing drilling configs
[21:18:25] <alex4nder> yah, copper is gummy/messy
[21:18:39] <ReadError> what causes some of them to look off?
[21:18:40] <djdelorie> the net result was 10 IPM max, and yes, I need backlash compensation
[21:18:49] <djdelorie> my cnc machine is made of plywood, it wiggles
[21:18:56] <jdhnc> tom_itx: g55 offsets seem to work good, thanks
[21:18:59] <ReadError> ohh
[21:19:00] <djdelorie> the top grid is "full wiggle mode" :-)
[21:19:18] <alex4nder> djdelorie: you're going to have the most advanced control system, with a sillyputty worksurface
[21:19:18] <ReadError> alex4nder: you need backlash compensation?
[21:19:25] <djdelorie> the pattern is: each *diagonal* is drilled in sequence, alternating directions, to maximize the backlash
[21:19:31] <alex4nder> ReadError: everyone could use a little
[21:19:57] <ReadError> ill probably try with your config first
[21:20:02] <ReadError> and see where i need to change stuff
[21:20:08] <alex4nder> you do that
[21:20:13] <Thadius> tomorrow i order my v90
[21:20:15] <djdelorie> alex4nder: this machine is the "learning machine" so that's the idea. The same electronics and software will be used in the next machine, which hopefully will be more physically robust
[21:20:26] <ReadError> Thadius: PICS PICS PICS
[21:20:28] <alex4nder> djdelorie: yah, it's a reasonable thing to do
[21:20:31] <ReadError> i been wanting to see some good ones of that
[21:20:34] <djdelorie> but really, today's stuff was all in gcode anyway
[21:20:57] <djdelorie> I'm working on an excellon to gcode converter
[21:20:58] <Thadius> oh i'll have pics and video, from assembly to test
[21:21:13] <ReadError> niiice
[21:21:24] <ReadError> that was one i was seriously looking at for routing
[21:21:25] <alex4nder> djdelorie: I think the next change I make is a spindle modification,,.. and then it's on to servos.
[21:21:32] <alex4nder> with better control
[21:21:50] <ReadError> how much more is a servo setup
[21:21:53] <ReadError> vs stepper
[21:22:18] <alex4nder> djdelorie: are you planning on doing motion control/kinematics on your boards or keeping that under Linux?
[21:22:23] <alex4nder> ReadError: 3 times?
[21:22:27] <alex4nder> for a reasonable setup
[21:22:35] <alex4nder> obviously you can go more or less.
[21:22:37] <ReadError> ah wow
[21:22:45] <djdelorie> linuxcnc is managing the path generation. My controllers just keep the motors where linuxcnc tells them to be
[21:22:46] <alex4nder> but your problems aren't going to be that you don't have servos.
[21:22:53] <alex4nder> djdelorie: sure, but what's your long term plan
[21:23:00] <djdelorie> "have fun"
[21:23:06] <alex4nder> ... I mean for your software architecture
[21:23:22] <djdelorie> the controllers simulate steppers, I was going to leave them like that
[21:23:25] <alex4nder> cool
[21:23:53] <djdelorie> they're just horribly overpowered, overprecise, overexpensive steppers :-)
[21:24:12] <ReadError> djdelorie: so why did you go balls out on the electronics and not the machine?
[21:24:24] <ReadError> any reason?
[21:24:32] <djdelorie> so far, the only $$ I've spent has been on the electronics
[21:24:56] <alex4nder> there's always a bigger machine.. but you plateau on your control electronics pretty quickly
[21:25:06] <djdelorie> and I write GCC ports for a living, and have a degree in electrical and computer engineering, so the electronics is the part I'm best at anyway
[21:25:22] <djdelorie> it doesn't cost money to change software :-)
[21:25:30] <alex4nder> yah
[21:25:40] <alex4nder> and you don't have to rewire. :/
[21:27:21] <Thadius> anyone ever use any of the vetric software?
[21:28:02] <Thadius> cut2d, photocarve ect
[21:28:31] <djdelorie> well, you have to rewire the electronics occasionally
[21:35:14] <jdhnc> I use cut2d
[21:47:22] <Thadius> hows it working out for you?
[21:48:15] <jdhnc> for what I do, it works great. Simple, easy to use.
[21:48:40] <jdhnc> new version out a few weeks ago fixes some quirks
[21:49:22] <jdhnc> I've been playing with the demo of ArtCam this evening, seems to be similar, but more featured. Can't save any of my toolpaths with the demo version though.
[21:54:32] <joe9> how bad is the vactra #2 oil for health? It is pretty smelly and I am around it all the time. not sure if that is a good idea or not?
[22:03:50] <djdelorie> I'm pretty smelly, and I'm around me all the time... so far so good...
[22:12:00] <joe9> http://www.cnccookbook.com/CCCNCGCodeCoordinates.htm good gcode startup material here.
[22:16:19] <alex4nder> yoh
[22:25:34] <joe9> alex4nder: you don't like it?
[22:25:47] <alex4nder> like what?
[22:31:48] <joe9> alex4nder: this http://www.cnccookbook.com/CCCNCGCodeCoordinates.htm gcode startup material
[22:32:54] <alex4nder> yah, the info there is cool
[22:33:40] <alex4nder> joe9: you milled anything yet?
[22:34:23] <joe9> alex4nder: no, reading up on gcode. next step: write and use a simple gcode to measure backlash using a dial indicator.
[22:35:27] <joe9> so, linuxcnc is a Fanuc dialect, correct?
[22:35:57] <alex4nder> living life on the edge
[22:36:12] <joe9> alex4nder: why do you say that?
[22:36:32] <alex4nder> I was trying to make a joke. ;)
[22:36:40] <joe9> oh, ok. thanks.
[22:36:52] <jdhnc> this code looks like it works on my 2.5.0 system, but the coord. offsets do something different on my 2.4.6 one
[22:37:00] <alex4nder> joe9: you trying to jump straight into milling PCBs?
[22:37:27] <joe9> no, I plan on doing something on wood or plywood. learn more.
[22:37:34] <joe9> before embarking on milling pcb's.
[22:38:03] <joe9> I have a lot to learn: gcode, how to clamp stuff down, touch-off's, homing or limit switches
[22:38:07] <alex4nder> well I commend you being thorough.
[22:38:21] <joe9> learn them and then go pick up the pcb stuff.
[22:38:29] <joe9> is there anything that I need to add to the list?
[22:39:34] <alex4nder> you're going to end up learning to mill fixtures for your PCB
[22:39:45] <alex4nder> so maybe do them in plywood first or something
[22:39:50] <joe9> i do not need to be an expert at gcode. but, I think I should be good enough to write a few lines here and there. and, also be able to tell if something is not correct.
[22:40:04] <joe9> alex4nder: ok, thanks.
[22:43:50] <alex4nder> ssi: you online?
[22:45:19] <djdelorie> added software debouncing to my limit switches, homing works flawlessly now :-)
[22:45:41] <djdelorie> JT-Shop: I got the "machine active" logic figured out, url in a moment...
[22:45:50] <joe9> djdelorie: cool. I want to add limit switches and homing too in the next day or so.
[22:46:06] <djdelorie> I'm using the "everything on one pin" configuration
[22:46:12] <asdfasd> finally added separate button for touch off Z
[22:46:20] <alex4nder> asdfasd: what're you touching off of?
[22:46:21] <joe9> i use steppers though.
[22:46:27] <djdelorie> there's a trick to getting the home+limit+range+etc working right
[22:47:02] <djdelorie> the hardware equivalent to what I did is a switch and cap to ground, and a pullup. I.e. it goes active immediately, but there's an 0.1 sec delay to go inactive
[22:47:04] <asdfasd> Im touching always wrong axis, so I added button for Z only
[22:47:09] <djdelorie> ;-)
[22:47:20] <alex4nder> asdfasd: oh, in software.
[22:47:30] <joe9> djdelorie: good idea.
[22:47:55] <asdfasd> I edit several files finally working, such a headache
[22:47:55] <djdelorie> I looked at the debounce module, but it was symmetrical, and I didn't want a delay on *hitting* the limit
[22:48:46] <joe9> djdelorie: what was your cap and pullup ratings?
[22:48:51] <joe9> s/was/is/
[22:48:55] <djdelorie> like I said, I did it in software
[22:49:00] <joe9> oh, ok.
[22:49:15] <djdelorie> there's an 0.1 sec delay timer that's reset whenever the limit logic is active
[22:49:41] <djdelorie> should be do-able in a HAL component too though
[22:49:42] <joe9> is that a plugin to linuxcnc or is it gcode?
[22:49:52] <djdelorie> it's in my firmware
[22:50:04] <joe9> oh, in the driver code?
[22:50:12] <djdelorie> in the RX62T chip :-)
[22:50:24] <joe9> ok, makes sense.
[22:50:58] <djdelorie> the controller lets you mix physical switches and map them to one of two output limit pins; the debounce is done on the output pin, not the switches
[22:54:42] <djdelorie> http://www.delorie.com/cnc/machineactive.comp
[22:57:46] <djdelorie> side effect - the debounce timeout means you can now *see* the axes back off during homing :-)
[22:59:31] <Thadius> quick question, 2.5d is just essentially z axis goto, cut depth, on to next...while 3d when cutting is the ability to move along x and y while having z constantly adjusting positioning based on gcode/project?
[22:59:48] <alex4nder> basically
[23:00:09] <alex4nder> but 2.5D is not always just a 'goto', depending on your cutting strategy
[23:00:36] <alex4nder> like, you can start pocketing with a spiral Z drop
[23:02:17] <Thadius> i see, however 2.5d does not = something like a face carved into or out of a piece of wood, so to speak
[23:03:58] <alex4nder> eh, it's kind of vague
[23:04:07] <alex4nder> you couldn't do a sphere and have it be 2.5D
[23:04:18] <alex4nder> but you could probably do half a sphere, and it would qualify.
[23:04:19] * djdelorie thinks 2.5D means "anything you can do with a generic XYZ 3-axis mill"
[23:06:34] <Thadius> so something of this nature is doable with 2.5 Cam software? http://www.designscomputed.com/coin_pics/amero_20_2007_circ.jpg
[23:07:12] <djdelorie> probably depends on the specific cam (did you mean cad?) software
[23:07:54] <alex4nder> Thadius: a lot of "2.5D CAM software" would be able to do each of those faces.
[23:08:48] <alex4nder> some is going to be better than others
[23:09:24] <Thadius> i meant CAM, and i'm just trying to secure my peace of mind as to which CAM software i go with
[23:09:39] <alex4nder> what're you looking at so far?
[23:09:59] <Thadius> Cambam, and the Vectric cut2d/cut3d
[23:10:05] <alex4nder> ah
[23:10:15] <Thadius> i'm just curious about the cut2d/3d
[23:10:21] <alex4nder> good news is that you can try both out
[23:11:11] <Thadius> ya, i have cut2d, guess i should design up something that more resemble the link i posted
[23:11:42] <Thadius> i was just happy to import my basic designs and have cut2d path them, and then do what i wanted in the preview
[23:13:20] <alex4nder> that reminds me: cambam is out for linux now
[23:13:23] <jdhnc> it's pretty nifty for what it does.
[23:14:15] <jdhnc> new one opens .dwg directly
[23:19:50] <mrsun> alex4nder, and where do you find a linux version ?
[23:26:40] <kb8wmc> is anyone running the Temperature Control Circuit developed by Anders Wallin to run under LinuxCNC? http://www.anderswallin.net/2010/11/temperature-control-circuits/
[23:27:52] <alex4nder> mrsun: http://www.cambam.info/ref/ref.linux
[23:40:25] <jdhnc> is there a way to jog, kill spindle, etc. for manual tool changes?
[23:43:34] <mrsun> M5 to kill spindle? :)
[23:43:44] <mrsun> G0 for rapid ...
[23:43:46] <mrsun> ? :P
[23:43:49] <mrsun> or what do you mean? :P
[23:44:09] <mrsun> or is it M4 to kill spindle? :P
[23:44:11] <mrsun> cant remember :P
[23:44:48] <jdhnc> I can add all that to the program. I wanted to be able to jog Z and touch off after manually changing the tool
[23:47:23] <djdelorie> jdhnc: I asked that a few days ago, there wasn't an obvious solution. I changed my scripts to produce separate gcode files for each tool
[23:49:24] <mrsun> but if you do a tool change in the gcode linuxcnc goes to the tool change position and stops the spindle and waits for UI input ?
[23:52:42] <mazafaka> mrsun: m3 (clockwise) and m4 (counter-clockwise) start to rotate the spindle in different directions
[23:52:58] <mrsun> ahh yes =) so its M5 then =)
[23:53:48] <mazafaka> I do not know the tool changing routine.
[23:54:18] <mazafaka> At this time of day, you hardly can ask the Herculesses of the EMC
[23:54:27] <jdhnc> I've been using separate files also.
[23:54:55] <jdhnc> Looks like there is a new hal_manualtoolchange that lets jogging/etc work while paused for tool change.
[23:55:03] <mazafaka> I meant Mr. crade.. or Mr. archivis.. or Mr. skunkwor... or Mr. JThorntho...
