[00:23:56] <dmess> hi all
[00:38:21] <Jymmm> Does having a printer that goes into standby drawing 4 Watts sound liek a lot?
[00:42:30] <jepler> 4W*1year*.15$/kWh = $5.259
[01:39:12] <Jymmm> Eh, it's kinda loud as it never truly goes into standby. I wonder if there's some way to automatically turn it on/off
[01:40:33] <dmess> keep it running :)
[01:40:51] <Jymmm> what aprt of loud didn't you get?
[01:56:19] <sed_> Anyone here want to help with homing?
[02:02:04] <Jymmm> sed

[02:23:29] <sed_> youtube crashes for me. Slow Connection
[02:24:13] <sed_> Its time to go home, Thank you for your assistance!
[07:40:35] <pjm__> good morning
[12:14:36] <Valen> mmmm mobile phone interwebalicious
[12:55:51] <skunkworks_> SWPLinux: I don't see the g540 config files anywhere on gecko's site.. Do you know if they where put somewhere?
[12:57:50] <Valen> When dad is milling now with the linear scales with EMC etc, he is seeing around .1mm vibration on the display (100 counts) during a heavy cut, will that cause problems when its fully CnCed?
[12:58:52] <cradek> do you think the table is actually moving like that?
[12:59:14] <archivist> old sloppy mill yes
[12:59:43] <cradek> I don't know what will happen
[12:59:59] <archivist> and spring in the leadscrew
[13:00:44] <archivist> we all have a different idea of "heavy cut" as well
[13:14:47] <pjm__> pjm__ is now known as pjm
[13:15:17] <pjm> pjm is now known as Guest73622
[13:26:48] <Guest73622> Guest73622 is now known as pjm
[13:27:07] <pjm> pjm is now known as pjm_
[13:43:52] <Valen> god damn mobile phone internet
[13:44:18] <Valen> I dunno if its moving that far
[13:44:42] <Valen> its doing a 8mm deep cut 20mm wide or so i think
[13:44:52] <Valen> 1600RPM
[13:45:28] <cradek> if it's real, emc will probably compensate because the variation is much slower than the servo cycle (this is surely true if he can see it in the display)
[13:46:01] <cradek> if it is not real, and the feedback is bad for some reason, it will not work well. it might oscillate or something.
[13:46:09] <cradek> hard to say which is true
[13:46:30] <Valen> hmmm actually oscilation on an input would be a really bad thing
[13:47:03] <Valen> because it will "correct" even if its not actually moving, or if the movement is taken up by the "spring" in the system
[13:48:19] <Valen> and odds are it'd be something like a fairly powerful correction as its thinking its moving the wrong way so it'll really ramp it up.
[13:50:06] <anonimasu> Valen: I think you will end up causing more oscillation trying to keep the mill in place
[13:50:07] <cradek> yeah that's why I ask if it's indicating real motion.
[13:50:25] <Valen> hmm I dunno
[13:51:05] <toastatwork> it's all in your mind, man.
[13:51:21] <Valen> what would you normally see on a metal milling machine?
[13:51:22] <anonimasu> Valen: I think if you have a sloppy machine you are better off not using linear scales for positioning it
[13:51:27] <Valen> its new
[13:51:50] <anonimasu> Valen: on a cnc, or a manual one?
[13:51:53] <toastatwork> sorry for coming in on the ass end of a conversation but what's the indicator problem?
[13:52:05] <anonimasu> toastatwork<Valen> When dad is milling now with the linear scales with EMC etc, he is seeing around .1mm vibration on the display (100 counts) during a heavy cut, will that cause problems when its fully CnCed?
[13:52:28] <toastatwork> ballscrew machine, leadscrew machine?
[13:52:35] <toastatwork> how much backlash
[13:52:38] <toastatwork> gibs tight?
[13:52:59] <archivist> chinese or quality
[13:53:03] <Valen> leadscrew currently, but I believe (or at least i think) he has the slide thats reading the vibration locked down
[13:53:15] <Valen> I'll have to double check that
[13:53:18] <toastatwork> is he climb or conventional milling
[13:53:37] <Valen> dunno, I'm just the electronics person, It shouldn't make any difference anyway
[13:53:44] <anonimasu> oh, yes it does
[13:53:46] <cradek> if it's not moving (locked) but the dro says it is, fix that
[13:53:57] <toastatwork> oh and make sure the locks work
[13:53:58] <cradek> dro mounting is bad maybe
[13:54:06] <toastatwork> we have a mill where the gibs don't actually lock up when you lock them.
[13:54:20] <Valen> ours didnt, that was fixed
[13:54:21] <anonimasu> I'd grab the cable and ~ it
[13:54:32] <anonimasu> and see if the dro changes
[13:54:45] <Valen> what would you expect to see on a DRO type readout doing some decent steel cutting?
[13:55:05] <toastatwork> a locked axis should see almost no movement.
[13:55:14] <cradek> change smoothly according to machine position
[13:55:15] <Valen> almost being a number of?
[13:55:25] <cradek> but locked - what he says
[13:55:32] <toastatwork> if it jitters, it should be .001 or less
[13:55:41] <Valen> inches or mm?
[13:55:44] <toastatwork> inches
[13:55:56] <anonimasu> with a decent machine much less then +/-0.01
[13:55:59] <cradek> .1mm is huge
[13:56:00] <toastatwork> even when I get the whole machine bucking back and forth, i don't see movement on the scales
[13:56:08] <toastatwork> on a well set up bridgeport
[13:56:16] <anonimasu> which is very close to what toast said
[13:56:52] <Valen> so around .025mm or so would be the "worst case" to aim for
[13:57:03] <Valen> (for the locked axis)
[13:57:03] <archivist> I can see more than .1mm on a manky machine we have in the basement
[13:57:14] <toastatwork> don't "aim" for a number here
[13:57:15] <toastatwork> the axis isn't actually moving, it's the scale feeling vibration
[13:57:20] <Valen> on a locked axis or just when your pushing
[13:57:27] <anonimasu> it shouldnt move if it's locked
[13:57:38] <Valen> yeah i know that
[13:57:53] <anonimasu> so if anything aim for 0
[13:57:58] <Valen> but its like an anti-backlash ballscrew, the backlash isn't 0 its just "not much"
[13:58:12] <anonimasu> but a screw isnt the same as a locked axis
[13:58:54] <toastatwork> ^
[13:59:05] <archivist> dont climb mill with backlash and an acme screw
[13:59:13] <toastatwork> what is fishy is if the machine was actually moving that much
[13:59:21] <Valen> your missing the point, anonimasu, I don't think you would ever have 0 readings when the whole machine is shaking around, just because the aluminium and glass in the scale wobbles different to the way the cast iron bed
[13:59:22] <toastatwork> endmills would be breaking left and right
[13:59:23] <toastatwork> especially in steel
[13:59:59] <Valen> its doing a 8mm deep 20mm wide cut, +-.1mm isnt actually going to make a difference to the mill lol
[14:00:06] <anonimasu> toastatwork:
http://www.io23.net/ul/files/lathe05.png
[14:00:13] <toastatwork> uh, it is if it's jerking back and forth
[14:00:36] <Valen> I wonder if that is what is causing it, the scale body is vibrating differently to the steel bed
[14:00:39] <toastatwork> it will absolutely snap an endmill if it suddenly moves in .1mm for one flute
[14:00:55] <toastatwork> pull on the scale?
[14:01:05] <toastatwork> see if it feels loose?
[14:01:24] <Valen> its not loose, but it is a meter long and only supported at the ends
[14:01:25] <toastatwork> anonimasu cool
[14:02:01] <toastatwork> and you aren't breaking endmills.
[14:02:08] <Valen> not doing the big incline one anonimasu
[14:02:09] <anonimasu> toastatwork:
http://www.io23.net/ul/files/lathe07_2d.png
[14:03:11] <anonimasu> Valen: no, I dont have means to machein that in a single setup
[14:03:58] <Valen> aww thats a shame it looked really cool ;->
[14:04:19] <toastatwork> you could try supporting the scale in more than one place
[14:04:19] <toastatwork> all the scales we have are supported in the middle and on the ends
[14:04:19] <anonimasu> and, my other issue is having the spindle off center..
[14:04:23] <Valen> machine the bed up, weld it to the base and go from there
[14:04:42] <anonimasu> Valen: done bring welding into this.
[14:04:53] <Valen> lol everybody hated on it?
[14:04:58] <anonimasu> Valen: unless you have a f-huge oven I can borrow
[14:04:59] <anonimasu> :)
[14:05:18] <Valen> doesn't need to be that hardcore
[14:05:23] <anonimasu> it does
[14:05:38] <anonimasu> :)
[14:05:56] <Valen> i mean the oven, couple of cement bricks, some elements a good book and a kitchen timer and your set
[14:06:01] <toastatwork> or uh
[14:06:20] <anonimasu> um.. tolerance stacks
[14:06:20] <toastatwork> just drill and tap some holes in the table for like 1/4 bolts
[14:06:33] <toastatwork> and make yourself a little aluminum clamp
[14:06:35] <toastatwork> that just bolts on
[14:06:59] <anonimasu> toastatwork: I had a question for you about offsetting the spindle from the rails
[14:07:09] <archivist> tolerance RMS add if you are lucky
[14:07:26] <toastatwork> it's not like you've got a load here, it's just to make sure the scale isn't carrying on like some sort of drunk in a hurricane
[14:07:26] <toastatwork> anonimasu shoot
[14:07:41] <toastatwork> also if i ping out i apologize but the wireless here is starting to act up
[14:08:10] <anonimasu> toastatwork: rails one one side, and spindle on the side
[14:08:17] <anonimasu> not between rails
[14:08:22] <toastatwork> like a commercial cnc does it.
[14:08:45] <Valen> toastatwork, yeah I'll have a look at the scale
[14:08:56] <toastatwork> that's a more rigid setup.
[14:08:56] <toastatwork> big roll lathes do that.
[14:09:03] <toastatwork> you lose some envelope though
[14:09:08] <toastatwork> which can suck for a hobby machine
[14:09:10] <Valen> I'll try and head up to his place next time he is doing some stuff and i'll just wedge it with something and see if it effects it
[14:09:54] <anonimasu> hm, I see, I'll re-arrange a bit and throw a drawing :)
[14:09:57] <skunkworks_> jepler: with a 9A drive you could probably comfortably accellerate at 2g :) (with headroom)
[14:10:24] <toastatwork> anonimasu: one of the good things about the "Traditional" engine lathe setup is that the cross slide is really maneuverable
[14:10:47] <toastatwork> if you don't care about that, then the offset head is a good way to go
[14:11:00] <anonimasu> I dont
[14:11:18] <anonimasu> I can fit a tailstock with that setup too
[14:11:23] <anonimasu> easier
[14:11:35] <toastatwork> yep
[14:11:43] <toastatwork> also you can machine past the tailstock
[14:11:46] <toastatwork> which is invaluable
[14:11:55] <toastatwork> and also make the tailstock programmable.
[14:12:02] <anonimasu> only question is how much the cutting force will end up on my rails
[14:12:14] <toastatwork> dunno
[14:12:15] <anonimasu> it's about 3700N per mm2 of material removal..
[14:12:27] <anonimasu> with 80% down \
[14:12:55] <toastatwork> our machines with rails do not use huge rails
[14:13:01] <toastatwork> the castings are massive, but the rails are comparatively teeny
[14:13:07] <anonimasu> like 5550N, for a 3mm deep cut
[14:13:34] <Valen> 3mm is a fairly deep cut in steel on a hobby machine
[14:13:54] <anonimasu> this is a tiny machine too, so if you put the cut depth in compairsion to the machine size spindle power will be limiting that
[14:14:11] <anonimasu> let me run away for a second I'm gonna start writing down some numbers when I get back
[14:14:13] <anonimasu> :)
[14:14:20] <toastatwork> the one thing you do need to watch out for is that a suddenly reversing load on a rail
[14:14:23] <toastatwork> will damage it
[14:14:32] <toastatwork> if the reversal overcomes the preload
[14:14:54] <toastatwork> i.e. the first time you crash it
[14:15:30] <toastatwork> so given the choice, get the rails with the highest preload
[14:15:37] <toastatwork> no matter what size you pick
[14:15:51] <toastatwork> since I don't think you'll be moving 2000 in/min in rapid
[14:17:16] <Valen> what is the mechanism of damage for that?
[14:17:36] <toastatwork> false brinneling
[14:17:47] <toastatwork> the rolling elements come out of contact with the rail, and then are hammered back
[14:18:00] <Valen> making some dents in stuff
[14:18:07] <toastatwork> yep
[14:18:11] <toastatwork> we've got a grinder that has that damage, it's a pain in the ass
[14:18:26] <Valen> if you have a slide type thing rather than a roller would it be less of a problem?
[14:18:34] <toastatwork> you mean a box way
[14:18:35] <toastatwork> ?
[14:18:42] <Valen> i may do
[14:18:46] <toastatwork> plain bearing etc
[14:18:47] <Valen> lol
[14:18:50] <toastatwork> yeah, those are really crash resistant
[14:18:58] <toastatwork> because they're hydrodynamic, there's really nothing to damage
[14:19:06] <Valen> a bushing rather than anything with balls in
[14:19:32] <toastatwork> i wouldn't go so far to say a bushing, because they're a little different
[14:19:34] <archivist> floating on the oil
[14:19:43] <toastatwork> but a plain bearing/box way will not be damaged by a hard crash
[14:20:00] <Valen> an air bearing now that would probably be the worst
[14:20:11] <toastatwork> not really
[14:20:37] <Valen> I can see it actually damaging the bearing itself (more than the slide)
[14:20:45] <toastatwork> an air bearing can ground out as long as it isn't moving
[14:20:52] <toastatwork> which describes a crash pretty well
[14:21:00] <archivist> air bearing still have a huge area, balls do not
[14:21:05] <toastatwork> air bearing machines also tend to be light
[14:21:17] <toastatwork> and do not generate the crash forces a larger machine with other bearings would
[14:21:45] <toastatwork> and even in a bigger machine, i doubt the bearing would be damaged
[14:21:47] <Valen> I was more thinking the old run the tool into the chuck type crash
[14:21:51] <toastatwork> now if you lost air, that will destroy it fast
[14:22:03] <toastatwork> yeah, that's the kind of thing i'm talking about
[14:22:19] <archivist> * archivist admits nothing about "run the tool into the chuck type crash"
[14:22:33] <Valen> heavy would reduce force on the bearing as the inertia of the carrage would act to absorb it?
[14:23:08] <toastatwork> no, heavy machines tend not to have air bearings - that was my only point
[14:23:20] <Valen> true that
[14:23:23] <toastatwork> with a heavy machine you might have problems because the forces are so much greater and the drives so much more powerful
[14:23:33] <toastatwork> a big machine will continue going in a fairly spectacular crash
[14:23:38] <Valen> you can really crash it good
[14:23:55] <Valen> seen that page with all the pictures of the boat engine?
[14:23:55] <toastatwork> so where a lighter machine will be like "uh oh, better stop"
[14:23:57] <toastatwork> a big one just plows right along
[14:24:00] <toastatwork> as though nothing were going on
[14:24:01] <Valen> the really really big one
[14:24:10] <toastatwork> indeed
[14:24:12] <Valen> with a turbo that you could walk into
[14:24:23] <Valen> now they would have some funky tools lol
[14:24:26] <toastatwork> what about it?
[14:24:36] <toastatwork> lol
[14:24:54] <Valen> you could *really* fuck stuff up in that place
[14:25:20] <toastatwork> yep
[14:25:32] <Valen> I mean we could probably use the swarf off their stuff to make parts out of, just treat it like slightly wonky bar
[14:26:01] <anonimasu> iab
[14:26:10] <toastatwork> hammer it flat and you've got yourself 5/8ths bar stock.
[14:26:56] <anonimasu> toastatwork: I have a quote for thk rails..
[14:26:58] <anonimasu> :]
[14:27:09] <Valen> * Valen is sitting down
[14:27:19] <anonimasu> but, I am going with the cheap ones.
[14:27:30] <Valen> what was the thk quot
[14:27:31] <Valen> e
[14:27:49] <anonimasu> 326 eur per rail and carriage
[14:27:53] <toastatwork> anonimasu got a couple grand, we can sell you a linear carriage
[14:28:02] <toastatwork> all set up, ready to bolt on =)
[14:28:10] <Valen> thats actually pretty cheap (in a weird way
[14:28:21] <anonimasu> if you can make me a deal, for a xy stage for 600 eur we have a deal.
[14:28:40] <toastatwork> i can get you one of the twelve bearing pads inside the carriage for 600 eur
[14:28:43] <archivist> Valen, how big engines were made
http://www.shipsnostalgia.com/guides/William_Doxford_and_Sons#The_Manufacturing_Process
[14:28:56] <toastatwork> or two, possibly
[14:29:26] <Valen> on stupid mobile internet atm
[14:29:28] <Valen> tis sucky
[14:29:29] <anonimasu> thk seems really weird in that you have to preload them yourself..
[14:29:56] <anonimasu> https://tech.thk.com/en/products/thk_cat_main_fourth.php?id=1104
[14:30:17] <anonimasu> shs-30-lv
[14:30:19] <archivist> Valen, bookmark it and see on a proper monitor later, well worth a look for 1950s machines
[14:30:32] <Valen> ahh yeah i have seen that one
[14:30:36] <Valen> was pretty cool
[14:30:46] <Valen> I'd still like to see making the new ones
[14:31:10] <anonimasu> their tech docs are weird about preload
[14:34:26] <toastatwork> what is 600 eur in usd
[14:34:32] <toastatwork> i guess i could just google it
[14:34:52] <jepler> huh, you can type in: 600 eur in usd
[14:35:01] <jepler> $833.94 says the all-seeing eye of the illuminati
[14:35:21] <Valen> google knows all (jedi finger wave)
[14:35:34] <toastatwork> yeah, that's what i got too
[14:35:34] <toastatwork> WE MUST BE USING THE SAME WEBSITE
[14:35:34] <toastatwork> I think you could build your own air bearing carriage for that
[14:35:40] <toastatwork> but that would just cover the pads required, not anything else
[14:35:50] <toastatwork> i.e. the rail
[14:36:17] <toastatwork> oh well
[14:36:47] <anonimasu> * anonimasu nods
[14:37:14] <toastatwork> it would certainly have a nice surface finish, anyway
[14:39:34] <Valen> thats just one carrage though? not 2 axes?
[14:40:01] <toastatwork> yeah
[14:40:20] <toastatwork> you need a bunch of pads per axis, so it adds up fast
[14:40:27] <toastatwork> even if you use small pads
[14:40:40] <toastatwork> could probably make your own, though
[14:40:54] <toastatwork> some aluminum and a lapping plate, done
[14:43:28] <anonimasu> yeah
[14:49:41] <toastatwork> derp
[14:50:03] <toastatwork> i have no idea how many of these stupid graphite wafers i've cut, but it isn't enough and i'm out of material
[14:50:09] <toastatwork> i think i need 120 or some such
[14:50:23] <toastatwork> i have ~70?
[14:50:45] <Valen> whatcha making
[14:51:11] <toastatwork> the porous media part of 120 air bearings =/
[14:52:00] <Valen> yay fun compressed filth all the way
[14:52:23] <toastatwork> indeed
[15:16:27] <skunkworks_> heh - I think I was getting 32 in/s^2 confused with 32 ft/s^2 ;)
[15:18:01] <anonimasu> toastatwork: once the company you work for fires you and flips over because of the conjecture so your NDA ends up invalid, for sure I'll be looking at air bearings :]
[15:21:08] <toastatwork> lol
[15:21:44] <toastatwork> good to know i can find stable work in the hobby community
[15:21:52] <anonimasu> from google it looks like people are making porous media bearings out of edm graphite..
[15:22:12] <toastatwork> yep
[15:22:49] <toastatwork> really the only proprietary parts of our process are a) how we tune the bearings, and b) how we assemble them
[15:23:02] <anonimasu> tune means what?
[15:23:13] <anonimasu> how you clog the pores to make them give uniform pressure?
[15:23:14] <toastatwork> knowing what I know now, i would not dick with porous media on my own project unless I had a really good reason to do so
[15:23:34] <toastatwork> getting them to behave in every sense of the word, flow, uniformity, pressure
[15:24:22] <anonimasu> hmm, I wonder can you clog the pores with epoxy..
[15:24:43] <anonimasu> and use force/position gauges to measure how uniform they are..
[15:25:53] <toastatwork> all excellent questions
[15:26:02] <toastatwork> and my NDA wishes you well =)
[15:26:07] <archivist> hehe
[15:26:49] <anonimasu> haha
[15:27:26] <anonimasu> some day im going to do that experiment
[15:28:11] <anonimasu> though getting graphite here isnt too easy
[15:29:59] <toastatwork> also i just want to throw out that it's possible you buy graphite that won't work, period, for a bearing
[15:30:10] <toastatwork> which is why nobody else is any good at porous media other than new way
[15:30:41] <toastatwork> (one of the reasons why)
[15:34:42] <toastatwork> for a machine tool I'd be interested in using slot bearings without orifaces
[15:36:05] <toastatwork> the air consumption is massive but the dynamics of the bearing are supposed to be the best out of any design
[15:39:21] <anonimasu> indeed
[15:39:42] <anonimasu> they probably have suppliers that can supply the stuff they want
[15:39:51] <anonimasu> and gunk the other stuff off to edm shops
[15:40:19] <anonimasu> I saw some resin that ended up porous when you cast it
[15:40:27] <anonimasu> for making bearings out of
[15:42:01] <toastatwork> that would be cool
[15:42:42] <anonimasu> I think that grinder "axtrusion grinder"
[15:42:45] <anonimasu> or whatever tey call iot
[15:42:46] <anonimasu> it
[15:43:30] <toastatwork> not familiar with it
[15:43:41] <anonimasu> I'll find it later
[15:54:10] <anonimasu> toastatw1rk: I cant find it now that the precision machine design page is dead
[15:54:43] <toastatw1rk> oh, it was a sloccum thing?
[15:55:07] <anonimasu> yeah
[15:55:20] <anonimasu> it looked like epoxy
[15:55:26] <anonimasu> but gray
[15:56:03] <toastatw1rk> i thought that was his low viscosity hydrostatic grinder
[15:56:22] <toastatw1rk> dunno
[15:56:54] <anonimasu> nope, it was air bearing
[15:57:53] <anonimasu> sorry, it was new way porous air bearings.. they used -_-
[15:58:29] <toastatw1rk> haha
[15:58:37] <toastatw1rk> it's almost like we know the guy personally
[15:58:38] <toastatw1rk> =)
[15:58:58] <Valen> whats the advantage of a porous bearing Vs one that acts more like a hovercraft?
[15:59:05] <toastatw1rk> ...wat
[15:59:27] <toastatw1rk> i don't understand the question.
[15:59:45] <Valen> I assume you are pushing air through the graphite surface to make something like a fluid bearing?
[16:00:00] <toastatw1rk> yep
[16:00:02] <anonimasu> the hovercraft ones are sensitive
[16:00:05] <anonimasu> scratch them and they crash
[16:00:06] <Valen> how is it better than a plate with a bunch of holes?
[16:00:27] <archivist> millions of holes
[16:00:39] <Valen> yeah, but how does that make it "better"
[16:00:47] <anonimasu> more surface area = stiffer
[16:00:58] <Valen> surface area should be the same
[16:00:58] <toastatw1rk> k hold up
[16:01:14] <toastatw1rk> on air bearing, the flat parts of the surface do very little load handling
[16:02:32] <Valen> yeah?
[16:03:27] <toastatw1rk> it is wherever the air is being introduced that is actually "the surface" and has the highest bearing force
[16:04:00] <toastatw1rk> the further you get away from a slot or oriface, the lower the bearing force is
[16:04:00] <toastatw1rk> so what a porous media bearing does is make millions of very tiny orifaces to turn the entire surface into load bearing
[16:05:28] <toastatwork> grr
[16:05:50] <toastatwork> anyway
[16:07:54] <Valen> so the "force" isnt equal to the pressure under the surface * the surface area?
[16:08:41] <toastatwork> correct
[16:10:00] <toastatwork> but with a porous media bearing, it's about accurate
[16:10:12] <toastatwork> there's some falloff of pressure towards the edges
[16:10:22] <toastatwork> but in the middle it's mostly linear
[16:10:34] <Valen> heres a thought, porus media air bearing on a ballscrew
[16:10:44] <Valen> probabbly better on an acme style screw actually
[16:10:52] <Valen> mmmmm slidy
[16:11:06] <toastydeath> difficult to make
[16:11:20] <toastydeath> easier to just use a linear motor
[16:11:21] <Valen> if it was easy there wouldnt be any fun
[16:15:09] <Valen> Ahh, the bearing is riding in the viscious effect of the air itself
[16:16:01] <Valen> so the force is actually less than you would assume if you just looked at surface * pressure
[16:16:26] <Valen> because there are (in the case of orfice bearings) low pressure spots away from the injection site
[16:16:41] <toastydeath> yes
[16:17:13] <Valen> funky
[16:18:36] <toastydeath> but in practice p*a is a good approximation because of the oriface density
[16:19:46] <Valen> for a porous bearing anyway ;->
[16:20:14] <toastydeath> no
[16:20:43] <toastydeath> for an oriface bearing, because they drill a whole lot of orifaces
[16:33:47] <skunkworks_> LawrenceG: how goes it?
[16:46:18] <skunkworks_> Is the axis geometry parameter not in the docs yet?
[16:46:28] <skunkworks_> or am I not looking in the right place?
[16:50:57] <skunkworks_> ah - found it.
[16:57:33] <skunkworks_> question -
http://www.linuxcnc.org/docs/2.3/html/config_ini_config.html does clicking on any of the links that have [] (like 2.2.1. [EMC] Section ) take you to that section? or is this an IE issue?
[17:06:08] <skunkworks_> logger_emc: bookmark
[17:06:08] <skunkworks_> Just this once .. here's the log:

[17:24:04] <cradek> skunkworks_: works for me

[17:32:51] <pjm_> pjm_ is now known as pjm
[17:33:10] <pjm> pjm is now known as pjm1
[17:33:29] <pjm1> evening all, anyone know if the nickserv happens to be working today?
[17:34:18] <archivist> I think so
[17:34:36] <pjm1> ah ok odd, i will try again!
[17:41:18] <anonimasu> iab
[17:53:48] <skunkworks_> http://imagebin.ca/img/vHAluTY.jpg
[17:54:03] <LawrenceG> skunkworks, hey.... not too bad here... working on the servo card.... I put in a single axis trajectory planner that mostly works... it seems to misbehave on negative high speed moves... I think there is a hitch in the calculated pwm settings when the drive request more than -50%
[18:00:04] <Jymmm> LawrenceG: alex_joni SWPadnos... Wait for it to load
http://producten.hema.nl/
[18:00:39] <gene> Hi guys
[18:00:49] <Jymmm> Hey gene
[18:00:52] <skunkworks_> LawrenceG: your putting motion in your amp?
[18:00:58] <cradek> hi gene@pool
[18:01:16] <EbiDK|AWAY> http://www.viruscomix.com/subnormality.html Tetris :D
[18:02:24] <gene> I just plugged in that Saitek game controller, and /dev/xconsole was created, but I can't tail it or cat it. Its all lit up, but no buttons register any data... Whats next?
[18:03:39] <gene> Hi Chis, slower typing. only 9 fingers. I trimmed my ring fingernail with the jointer a week ago, ouch!
[18:03:42] <LawrenceG> skunkworks_, yea.. it has the smarts and a serial interface already... I have an application where a serial servo would be useful for 1 axis positioning
[18:04:46] <LawrenceG> skunkworks, no co-ordinated motion between axis is intended
[18:05:37] <LawrenceG> Jymmm, somebody had far too much time to build that website!
[18:08:15] <Jymmm> LawrenceG: I thought it was very creative
[18:09:49] <cradek> gene: I thought game controllers would create something under /dev/input. then you can use the hal_input component.
[18:10:22] <cradek> gene:
http://www.linuxcnc.org/docs/devel/html/man/man1/hal_input.1.html
[18:19:59] <gene> It did that also but I missed it. I have the wiki page 'a new approach' on another screen, and I'll yelp if that doesn't work.
[18:21:32] <gene> This pad/stick is a saitek P990, dual aanalog, and possibly more buttons than the P880 in the example.
[18:30:19] <frallzor> lo
[18:46:33] <gene> Ok, problem #1, even sudo can't write to /etc/udev/rules.d/50-input-permissions.rules. Why not?
[18:47:36] <cradek> yes root can write to that. how exactly are you trying to do it?
[18:49:50] <gene> sudo kate filename, but I found that a sudo vim filename worked just fine. something doofy with kate, as usual. Back to the script, thanks
[18:53:38] <frallzor> http://pici.se/435823/ http://pici.se/435824/ anyone want to guess why solidcam want to leave restmaterial and not just "kill" all? =)
[19:00:35] <gene> I guess I'll have to reboot after adding that udev rule, loaduser can't find SAITEK yet. brb
[19:03:18] <anonimasu> hmm
[19:03:51] <anonimasu> frallzorprobably because you are using the wrong kind of toolpath
[19:04:57] <frallzor> its zigzag
[19:05:01] <frallzor> what is the best for that
[19:05:11] <anonimasu> I'd do like paralell rough
[19:06:04] <anonimasu> and then do flowline finishing
[19:06:06] <anonimasu> if you have that
[19:06:35] <frallzor> define flowline
[19:07:22] <anonimasu> it's where you cut respecting surface normals to get a nice finish
[19:07:51] <frallzor> maybe its crossfinnish in solidcam?=
[19:07:54] <anonimasu> http://www.steptools.com/library/stepnc/ap238_samples/surface_machining/index.html <- good to look at
[19:07:56] <frallzor> looks like some web
[19:08:03] <anonimasu> yeah that sounds like that
[19:08:44] <frallzor> indeed it was
[19:08:48] <frallzor> but i found the biggest issue
[19:08:55] <frallzor> the distance between rows
[19:09:04] <anonimasu> for surface finish?
[19:09:08] <frallzor> it was 1mm at zigzag
[19:09:26] <frallzor> set to 0.5 and it looks really nice with flowline
[19:09:34] <anonimasu> there's a magical formula for what gives you the best finish
[19:09:48] <anonimasu> where the stepover is the same as the chip size
[19:10:25] <frallzor> how to see the chip size
[19:10:42] <anonimasu> you calculate that off speed/feed
[19:11:35] <frallzor> dont know that yet so It have to wait then =)
[19:12:04] <anonimasu> if you have any idea about the material you could look at dormer "smartselector" tool
[19:12:07] <gene> bah, damn konqi, how do I actually download joyhandle.ko as a friggin binary with it? A right click does something but goes away in 1/2 second.
[19:12:37] <anonimasu> :)
[19:13:06] <frallzor> well I know exactly what material it is :P
[19:13:35] <jepler> the joyhandle.ko from the wiki is probably useless to you, unless you happen to be running the exact same emc2 version as that page author
[19:13:51] <gene> 2.2.8?
[19:13:53] <jepler> you want to get joyhandle.comp and sudo comp --install joyhandle.comp
[19:14:15] <gene> ok, thanks
[19:14:31] <jepler> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?ContributedComponents#How_to_compile_and_install_a_component
[19:14:37] <jepler> > First, install the emc2-dev (sudo apt-get install emc2-dev) and build-essential packages (sudo apt-get install build-essential). If the component does not provide specific installation instructions, then try these general instructions:
[19:16:43] <gene> sudo comp, command not found. build-essentials is installed AFAIK
[19:18:43] <gene> no it wasn't! must have been in a previous life
[19:19:32] <gene> still getting
[19:19:34] <jepler> that paragraph lists two packages to install anyway
[19:19:34] <gene> gene@shop:~/emc2$ sudo comp --install joyhandle.comp
[19:19:34] <gene> sudo: comp: command not found
[19:19:35] <jepler> make sure you get both
[19:20:10] <gene> looks like one is the manpage?
[19:21:16] <jepler> sudo apt-get install emc2-dev
[19:21:33] <gene> looks like I can't get either package, and dapper is too old a gtk to run FF now...
[19:22:37] <gene> ok, that last worked :)
[19:23:01] <frallzor> * frallzor is a bit happy that he understands solidcam
[19:23:49] <anonimasu> :)
[19:24:00] <anonimasu> I wish I understood the thk rail mounting instructions
[19:25:26] <anonimasu> :@
[19:25:43] <frallzor> I wish I could my anything at all :P
[19:25:54] <frallzor> waiting for retrofitkit from damencnc =)
[19:29:45] <anonimasu> nice :)
[19:30:22] <frallzor> but the result is just a small wee little cnc for cibatoolmodels =)
[19:30:40] <gene> now where the heck did it put joyhandle.ko?
[19:30:58] <gene> on dapper
[19:31:11] <anonimasu> cibatool?
[19:32:54] <frallzor> PUR-foam, kind of
[19:33:11] <frallzor> but made in blocks for modelling
[19:34:48] <frallzor> http://pici.se/p/VYIETXpKm/
[19:34:54] <frallzor> this is a block of cibatool =)
[19:35:06] <frallzor> 1500x500x50 will last some time :P
[19:36:31] <gene> this looks odd, from a rebuild of joyhandle.ko: cp joyhandle.ko /usr/realtime-2.6.15-magma/modules/emc2/
[19:36:54] <gene> how does modprobe find it there?
[19:37:22] <cradek> hal finds it
[19:38:03] <gene> doesn't seem to, although the loadusr linee does not error now.
[19:38:31] <gene> I see a bunch of buttons, but only 2 respond.
[19:40:25] <gene> and now they are gone, and it does not now load
[19:40:43] <gene> it being the loadusr line
[19:42:31] <gene> humm I just overwrote my joypad_v3,hal with yours, I'll recheck
[19:43:37] <gene> nope:
[19:43:37] <gene> halcmd: loadusr -W hal-input -KRAL Saitek
[19:43:38] <gene> <stdin>:0: execv(hal-input) failed
[19:43:38] <gene> <stdin>:0: hal-input exited without becoming ready
[19:43:53] <cradek> you misspelled hal_input
[19:46:45] <gene> grrr, anybody want a sore finger? :)
[19:47:18] <frallzor> hmm how odd, my pocketmilling messes up real bad for some reason in simulation
[19:48:07] <EbiDK|AWAY> * EbiDK|AWAY curses the suckyness that is CyberCity
[19:49:06] <skunkworks_> gene: did you loose a few mm of finger?
[19:50:08] <gene> Can I assume show pin is real time? I can only see 2 events, one for the button called FRS and one for the button labeled 'analog', and yes, abouit 5mm of it.
[19:50:23] <gene> Hows Sam today?
[19:51:00] <skunkworks_> you are pretty lucky anyways.
[19:51:17] <skunkworks_> I am good - should be home working on the garage.
[19:51:43] <frallzor> http://pici.se/p/EkorscdhT/ anyone wanna guess why solidcam does this? =) How its supposed to be is pretty obvious but that little circlethingy isnt planned
[19:51:45] <gene> no other buttons generate an event. Great, good to hear.
[19:52:59] <gene> I take it garage=new skunkworks. Got pix?
[19:53:59] <EbiDK|AWAY> frallzor: Got some code for that too?
[19:54:10] <frallzor> hmm should have
[19:54:48] <frallzor> http://pastebin.com/m6426a9f9
[19:54:57] <frallzor> its the first thing it does
[19:55:05] <frallzor> do that odd beanshaped thing
[19:58:39] <skunkworks_> gene:
http://imagebin.ca/img/vHAluTY.jpg
[19:58:48] <anonimasu> it looks liek a rampin
[19:59:46] <skunkworks_> I lucked out when I was younger and just nipped the skin off the tip of my index finger in a jointer/planer.
[20:00:07] <skunkworks_> Hi Dad...
[20:00:10] <skunkworks_> ;)
[20:00:27] <frallzor> EbiDK|AWAY any ideas? =)
[20:01:48] <anonimasu> frallzor: do you have a leadin programmed?
[20:01:55] <frallzor> how to tell?
[20:02:14] <frallzor> it didnt do something like that on the 3dmilling
[20:02:46] <frallzor> and why would a leadin do the full depth on on spot and then do the rests in the steps i want?
[20:02:51] <frallzor> *on a
[20:03:15] <anonimasu> didsable the leadin and see
[20:03:29] <anonimasu> * anonimasu curses the cad program
[20:03:38] <gene> emc2 startup err at <
http://pastebin.ca/1488777>
[20:03:42] <anonimasu> I want to draw central lubing lines :@
[20:04:13] <EbiDK|AWAY> frallzor: I'm not sure, I'm not good at this stuff and haven't played with g-code in a few weeks. Only odd thing I can see is that you have some negative radi but I don't know if that's allowed or meaningful
[20:04:13] <frallzor> anonimasu dont know where it could be
[20:04:57] <frallzor> but I still dont see the meaning of a useless "lead-in" if that is what it is
[20:05:04] <frallzor> it does it first, then do the rest
[20:05:48] <frallzor> found them
[20:05:54] <frallzor> no leadins or ramp etc etc
[20:06:14] <anonimasu> that's weird
[20:06:48] <frallzor> but when i set it looks like there is
[20:06:57] <frallzor> origin where the odd shape is
[20:07:49] <anonimasu> hm, that's weird
[20:10:28] <frallzor> re-did operation, same thing
[20:12:40] <frallzor> I have no ideas on why its doing this =)
[20:13:00] <frallzor> I did the 3d-operation but cant figure out a pocket :P
[20:13:05] <gene> I got just a cut once before, slow learner I guess
[20:14:31] <frallzor> simple solution
[20:14:40] <frallzor> I used the pocket recognition, now it works
[20:15:00] <anonimasu> http://www.io23.net/ul/files/lathe1021.png
[20:18:34] <gene> <skunkworks>
http://imagebin.ca/img/vHAluTY.jpg. Thats quite a bit bigger project than mine was.
[20:19:07] <skunkworks_> It has been a few months :)
[20:19:14] <gene> Has anybody looked at <
http://pastebin.ca/1488777> yet?
[20:19:35] <gene> all by yourself?
[20:20:01] <skunkworks_> with a bit of help from friends
[20:20:06] <skunkworks_> for the heavy stuff
[20:20:12] <skunkworks_> but yes
[20:20:44] <gene> same here, I did 98% of it alone
[20:21:29] <gene> E_OUT_OF_COFFEE, brb
[20:23:05] <Jymmm> Does anyone know where to buy rack screws locally? HD and lowes dont carry the right ones. and I'm tired of these POS ones that just strip the head out
[20:24:18] <gene> Better screwdriver bit maybe?
[20:29:20] <gene> ok, found that one SAITEK != Saitek, but now there is another missing var, joypad_v3.hal:38: parameter or pin 'halui.jog-speed' not found
[20:29:33] <gene> and this is new ground for me...
[20:31:27] <jepler> the mapage says the pin is halui.jog.speed
[20:31:45] <jepler> also you need to specify [HALUI]HALUI=halui in your inifile -- you may not have activated halui yet
[20:32:13] <jepler> er, [HAL] HALUI = halui
[20:43:42] <gene> ok, brb
[20:48:33] <skunkworks_> I have really good luck with these
http://www.shop.com/+-a-vermont+american+philip+bits+%232-p226527167-g1-k24-st.shtml
[20:48:39] <gene> Looks like I need a whole bunch of pin aliases, huge diff between the show pin screen and the error msg named pin. Am I still missing a file.hal somehow?
[20:48:52] <skunkworks_> Jymmm: do you have a fastenal?
[20:52:42] <gene> emc says it needs a "joypad_v3.hal:63: pin 'input.3.abs-rz-position' does not exist" which is one I added for the A axis, I'll comment the A stuffs.
[20:55:33] <alex_joni> gene: the input.3.abs-rz-position might not exist for your joystick type
[20:56:57] <gene> without that, it is working! I have several sspare buttons and stick axises though.
[20:58:27] <gene> The right stick drives x & y, and the left stick drives z for to/from, left/right is unused. spindle is the two buttons at 9=on and 3(pm)=off
[21:01:46] <gene> running the logo in air, there is not an e-stop equ, so that also needs addressed. I have 9 spare buttons and another 8 axis pad left.
[21:02:55] <gene> Lots of toys. :) And the motion scaling seems to be good, I can creep up to 15 ipm. Great!
[21:04:46] <Jymmm> skunkworks 6 of em, thanks
[21:06:01] <gene> Alex: this is a Saitek p990, it has a few more buttons. Are they not used by joyhandle.ko?
[21:06:40] <alex_joni> gene: loadusr hal_input
[21:06:42] <alex_joni> then hal show
[21:06:53] <alex_joni> and you'll see what it detects, and what is available
[21:12:45] <gene> it doesn't show anything unless I "loadusr -W hal_input -KRAL Saitek"
[21:13:07] <gene> then it shows xyz stuff only.
[21:14:22] <gene> about 36 signals
[21:14:24] <Jymmm> skunkworks This is what I typically use...
http://www.homedepot.ca/wcsstore/HomeDepotCanada/images/catalog/2ed3ff24-deba-47b5-be0b-0290d1a5ca48_4.jpg
[21:16:54] <Jymmm> skunkworks Jsut shove it in a cordless drill and you're good to go
[21:19:03] <skunkworks_> right - that is what I do with those bits. (with a extention) but they seem to have a really good lifespan and have little teeth on the edges that grip. I use them for putting deck screws in.
[21:20:11] <Jymmm> skunkworks Ah, ok. someone suggested to use hex mushroom heads, might not be a bad idea.
[21:31:33] <gene> The 'torx' head stuff seems to be a better idea, bits last longer
[21:32:20] <skunkworks_> Yes - I agree
[21:33:34] <Jymmm> Yeah, and less of me having to drill out the stripped screws - Though I have a frog set now =)
[21:33:45] <sed_> Morning everyone, I am looking for help with homing and index bits
[21:34:55] <gene> and my back is about ~30~ so this project can wait. next time I'll post my joypad.hal & we'll see if we can mae a couple more things work. Thanks everybody.

[21:45:40] <frallzor> is 61000 lines of g-code much? =P
[21:46:01] <anonimasu> no
[21:46:07] <anonimasu> ยด
[21:46:14] <anonimasu> it depends on what your gcode does :]
[21:46:20] <frallzor> then i have another problem :P
[21:46:21] <archivist> for me yes
[21:46:34] <frallzor> it takes forever to run it in emc2
[21:46:50] <anonimasu> try g63
[21:46:51] <frallzor> even with jog = 6000 mm/min
[21:46:54] <frallzor> setting right?
[21:47:00] <anonimasu> one second
[21:47:58] <anonimasu> try g64
[21:48:05] <anonimasu> err adding in the start of your program
[21:48:25] <frallzor> one min, pastebin :P
[21:48:43] <frallzor> http://pastebin.com/m1a8f0b3c
[21:48:43] <anonimasu> Just throw it into your program somewhere :)
[21:49:02] <frallzor> the Q is, where, shitload of GXX
[21:49:17] <anonimasu> http://pastebin.com/m172aadc2
[21:50:05] <frallzor> should I see the difference? =)
[21:50:39] <anonimasu> line 11
[21:50:43] <anonimasu> G90 G00 G40 G55 G64
[21:51:57] <frallzor> how should one know what it does and why its there? :P
[21:52:07] <anonimasu> http://www.linuxcnc.org/docview/html/gcode_main.html
[21:52:16] <anonimasu> 1.22 G61, G61.1, G64 Set Path Control Mode
[21:52:34] <anonimasu> it makes your tiny line segments merge if they are colinear
[21:52:58] <seb_kuzminsky> that's not exactly true
[21:53:21] <frallzor> well it didnt help a bit :)
[21:53:24] <seb_kuzminsky> g64 makes it keep the feed at the commanded value, even if that means it can't follow the commanded path exactly
[21:53:26] <anonimasu> or round things off..
[21:53:41] <frallzor> even though Im not setup correctly, the speed remains the same at 6000mm/min
[21:53:58] <anonimasu> should it be faster?
[21:54:41] <frallzor> the 6000mm/min is waaaaaaaaaaay below that atm :)
[21:54:53] <frallzor> superwaaaaaaaaaaaaaaay even in the "simulation" in emc2
[21:55:17] <frallzor> so im guessing it might just be a configissue atm
[21:55:30] <frallzor> but does one tell emc2 the speed or while doing cam?
[21:55:55] <jepler> both, part of the configuration of emc is the maximum acceleration and velocity permitted by your motors
[21:57:47] <frallzor> and in the campart?
[21:58:31] <jepler> I dunno how your cam software works, but part programs specify the "F number" or feed rate as appropriate
[21:58:47] <jepler> your cam software might pick an appropriate value based on what you tell it about material, tooling and spindle
[21:59:13] <frallzor> issue is it only got materials like steel, Al etc etc
[21:59:20] <frallzor> not the one Im using
[21:59:24] <frallzor> or similar
[21:59:44] <frallzor> I might have to edit the PP too
[21:59:49] <frallzor> using generic fanuc
[22:02:43] <toastyde1th> what material are you using
[22:06:43] <anonimasu> toastyde1th: I have a picture for you in a sec
[22:06:58] <toastyde1th> k
[22:07:17] <anonimasu> http://www.io23.net/ul/files/Assembled%20Lathe.png
[22:07:23] <frallzor> toastyde1th in cam atm but planning to use cibatool
[22:07:31] <frallzor> *none in cam
[22:08:01] <toastyde1th> frallzor: i meant the physical material you're trying to cut
[22:08:25] <frallzor> not cutting anything yet, just trying to cam and run in emc
[22:08:33] <frallzor> but as I said, planning to use cibatool
[22:10:49] <anonimasu> * anonimasu yawns
[22:11:26] <anonimasu> toastyde1th: looks like a better arrangement dosent it?
[22:11:33] <toastyde1th> oh i didn't see the picture, sorry
[22:11:44] <toastyde1th> ...Where's the headstock?
[22:11:54] <anonimasu> not drawn/designed yet
[22:11:56] <toastyde1th> oh
[22:12:03] <anonimasu> im re-arranging everything with thk rails
[22:12:22] <anonimasu> for X as that will carry most load
[22:12:42] <anonimasu> and they had cad files ;)
[22:13:08] <toastyde1th> cool
[22:13:40] <anonimasu> im going with cheaper slides for the other axis..
[22:13:44] <anonimasu> err a cheaper slide
[22:13:50] <anonimasu> and drive it off center
[22:14:07] <toastyde1th> You could always put the headstock on the X axis
[22:14:42] <anonimasu> mhm, yeah
[22:15:25] <toastyde1th> really just a big plate parallel to Z, with the rails perpindicular
[22:15:37] <toastyde1th> that way you could mount the headstock, and also have a slot in it for tailstock
[22:15:39] <anonimasu> but then I need to slide the motor and all
[22:15:49] <toastyde1th> yeah just put the whole thing on the plate.
[22:16:08] <anonimasu> and I cant use a tailstock with that setup easily
[22:16:16] <toastyde1th> sure you could
[22:16:30] <toastyde1th> you have all that space above the Z axis as you've got it drawn
[22:16:39] <toastyde1th> just put a big tooling plate there.
[22:16:47] <toastyde1th> make the plate your X axis.
[22:16:57] <anonimasu> let's talk abotu the same axes because im lost
[22:17:04] <toastyde1th> nvm
[22:17:07] <anonimasu> the stuff my cad calls them :}
[22:17:10] <anonimasu> im not familiar with lathes
[22:17:24] <toastyde1th> oh uh, Z is toward and away from the spindle
[22:17:28] <toastyde1th> so length
[22:17:31] <toastyde1th> and X is the diameter
[22:17:34] <anonimasu> I see
[22:17:58] <anonimasu> I think sticking the X on top of my Z axis as I have it drawn is a good idea
[22:18:06] <anonimasu> I need that so I get the tooling height right too
[22:18:07] <toastyde1th> well, yes, that would be a standard lathe
[22:18:32] <anonimasu> btw..
[22:18:42] <anonimasu> make the spindle sliding, and stick another rail arrangement like I have..
[22:18:44] <anonimasu> for the Z
[22:18:46] <anonimasu> and another turret ;)
[22:19:02] <toastyde1th> why would you need three different movements for Z
[22:19:17] <toastyde1th> or am i confused
[22:19:22] <anonimasu> you are confused
[22:19:26] <anonimasu> I'll have only Z and X
[22:19:48] <toastyde1th> oh, you're saying make a twin turret lathe
[22:20:00] <anonimasu> yeah
[22:21:10] <anonimasu> I think I'll have the spindle stationary because it's easier, and have a rail below it with the tailstock
[22:21:33] <anonimasu> not as cool though
[22:21:49] <toastyde1th> we have a lathe at work where the spindle moves for Z
[22:21:56] <toastyde1th> and there's just a t-slotted plate for X
[22:22:04] <toastyde1th> neato machine
[22:22:09] <anonimasu> * anonimasu nods
[22:22:21] <anonimasu> I like the idea
[22:23:00] <anonimasu> I need to draw my motors up
[22:23:34] <anonimasu> I have some 0.66Nm servos
[22:23:39] <anonimasu> 1.6Nm peak
[22:23:45] <toastyde1th> i don't know anything about motor sizing
[22:24:02] <toastyde1th> unfortunately you might have just said "tomato waffle curling iron"
[22:24:14] <toastyde1th> i don't know how much force it takes to drive an axis =(
[22:24:16] <anonimasu> lol
[22:24:25] <anonimasu> depends on how you cut
[22:24:33] <toastyde1th> LIKE A BAT OUT OF HELL
[22:24:36] <archivist> sufficient suffices
[22:24:43] <anonimasu> indeed
[22:25:03] <toastyde1th> i demand overkill
[22:25:53] <anonimasu> well, for this machine they should be big enough :)
[22:26:27] <toastyde1th> i wish somebody made a really grunty small lathe, like, 5" swing, but 10 hp
[22:26:37] <toastyde1th> 5000 lbs
[22:27:19] <anonimasu> me too
[22:27:20] <anonimasu> and cheap
[22:27:32] <toastyde1th> monarch 10ee is about the closest i've found to that
[22:27:35] <toastyde1th> and the rivett 1020
[22:28:02] <Jymmm> SWPadnos:

[22:28:28] <anonimasu> I dont know if im going to bother to do the calcs about motors
[22:28:49] <anonimasu> I have them, and I have screws already
[22:28:57] <anonimasu> :)
[22:29:37] <toastyde1th> lol
