[02:51:57] <Loetmichel> mornin'
[21:28:58] <XXCoder> jdh: two steps, do half of circle, move clamps there in then do it on other side? would that work?
[21:29:35] <XXCoder> same design rig as you linked to, just has a hold in middle for yuou to move that center holder to other side
[21:29:49] <jdh> wasnt' me.
[21:29:53] <XXCoder> oh
[23:03:02] <anarchos> any tips on creating a bootable USB stick to use as a live "cd"?
[23:03:29] <anarchos> mine boots but then can't find/mount the ramfs (iirc) fs
[23:03:41] <somenewguy> skunkworks_ so you are saying no, linuxcnc can't handle that?
[23:05:05] <somenewguy> I want to tilt my head on my mill a few degrees off axis, then rotate my cooridnate system so my moves in XY are perpendicular to my twisted Z axis, meaning a move from x0y0z0 to x1y0z0 in the rotated coordinates would requrie a move in both X and Z
[23:05:47] <somenewguy> if you are just doing a liveCD and not a real install, would a VM work just as well?
[23:06:16] <anarchos> i just wanted to try it out before commiting to a real install :P
[23:06:44] <somenewguy> ok, I doubt you could move a machine in a VM, but you could do a sim atleast
[23:07:08] <somenewguy> anarchos I thought I'd seen u around here before, do you not use linuxcnc already?
[23:07:35] <anarchos> negative, using mach3 atm
[23:07:42] <anarchos> i've been around for a week or so though
[23:07:44] <anarchos> :P
[23:07:44] <somenewguy> I would say makehte switch
[23:07:57] <somenewguy> I used mach3 for about 2-3 months
[23:07:59] <somenewguy> on a mill
[23:08:11] <somenewguy> then I tried linuxcnc and love it way more, machine 3x more reliable
[23:08:18] <anarchos> cool
[23:08:29] <somenewguy> I don't think the issue was mach3 as much as windows, but still it fixed a lot of odd problems
[23:08:59] <somenewguy> namely my parallel port would spaz out every now and then and send commands onits own, couldn't nail the issue down, it happended rarly but it happened
[23:09:14] <somenewguy> ngcgui is worth the price of admission
[23:09:18] <anarchos> i 'spose if i can't get the USB live mode to work I could just do a real install
[23:09:30] <somenewguy> how long u been using mach3?
[23:09:32] <anarchos> I assume it's possible to non destructivly partition a disk from the installer?
[23:09:43] <somenewguy> yes it should be
[23:09:46] <anarchos> i'm pretty sure redhat 6 had that ability :P
[23:09:50] <anarchos> like a week
[23:09:54] <anarchos> i'm very new to CNC :P
[23:09:57] <somenewguy> iirc you can only really install linux after windows, not hte other way around
[23:10:06] <somenewguy> I reccomend just ditch mach3 and start learning linuxcnc
[23:10:20] <somenewguy> they are not all that different, but I belive linuxcnc is just better
[23:10:37] <anarchos> yeah
[23:10:51] <somenewguy> between the reliability of linux vs windows, and the ease of customization and the better community (in my experience) linuxCNC has just worked out better for me
[23:10:59] <anarchos> i'm a linux/mac guy, but have been forcing myself into windows recently :P
[23:11:07] <anarchos> all the CAD/CAM stuff I use are windows
[23:11:08] <somenewguy> I'm sorry
[23:11:12] <somenewguy> you should see help
[23:11:15] <somenewguy> oh
[23:11:17] <somenewguy> well
[23:11:19] <somenewguy> yeah
[23:11:23] <somenewguy> if yo uhave good/real CAD software, I can't fault you
[23:11:34] <somenewguy> the only reason I have a windows partition is I used to have a solidworks license
[23:11:35] <anarchos> and then all the "hobbiest" type stuff seems to revolve around mach3, so i figured i'd do that
[23:11:56] <somenewguy> I haven't nuked it yet, in the bizzare hope I will get it back someday
[23:12:00] <somenewguy> what kind of stuff you make?
[23:12:08] <anarchos> i
[23:12:16] <anarchos> i attempt to make bike parts :P
[23:12:43] <somenewguy> oh cool, just got into mtb myself, its the reason im behin the comptuer today instead of in the shop, can't stand lol
[23:13:04] <anarchos> lol
[23:13:08] <anarchos> it'll do that to ya
[23:13:27] <somenewguy> but its about the same price as a gym membership, and about 100X more fun
[23:13:42] <somenewguy> although I must say trees can be real jerks
[23:13:54] <anarchos> i live in the greatest place on earth, so it's nearly impossible to not be into mtb'ing
[23:14:01] <somenewguy> utah?
[23:14:01] <anarchos> :P
[23:14:03] <anarchos> Whistler
[23:14:09] <somenewguy> whistler?
[23:14:15] <anarchos> Jah
[23:14:48] <somenewguy> so the german side of canada?
[23:14:59] <anarchos> i guess?
[23:15:02] <anarchos> we have a german side? :P
[23:15:53] <somenewguy> i assumed from the jah
[23:16:44] <anarchos> that was my attempt at being jamaican :P
[23:17:03] <somenewguy> basically the same thing
[23:18:00] <somenewguy> so what kind of mill you got?
[23:18:05] <anarchos> X2
[23:18:10] <somenewguy> its nice having a bigger newb than me on here lol
[23:18:38] <anarchos> i live in an apartment so not much room for anything bigger
[23:20:03] <anarchos> omg it booted!
[23:20:04] <anarchos> cool
[23:20:07] <somenewguy> congrats
[23:20:19] <somenewguy> nice looking mill, I only have a Taig so we are in the same league
[23:20:34] <somenewguy> my excuse is my 140 yo work shop floor won't support the weight of real equiptment
[23:21:58] <somenewguy> I have a circuit to finish trying to design so I can try milling aPCB on the mill tomororw, but I'll be lurking so good luck and feel free to ask questions
[23:22:28] <somenewguy> also look at the examples for how to make NGCGUI subroutines, its so stupid easy I feel dumb for not notcing for like 4 months
[23:26:53] <anarchos> awesome, thanks
[23:27:06] <anarchos> i just took the plunge and have repartitioned my disk in half
[23:27:24] <anarchos> we'll see how it works out. Ubuntu is surprisingly very nice, the installer was slick.
[23:27:32] <anarchos> i'm used to text mode debian installs :P
[23:28:12] <somenewguy> yeah, ubuntu nailed the installer in like 08, Iactually think the newest ones starting in like '12 or so are worse, they offer less fine control
[23:28:23] <somenewguy> ubuntu is turning more and more into a mac product sadly
[23:28:35] <XXCoder> yeah
[23:28:51] <somenewguy> i reccomend linuxmint for flks that are new to linux now, but thats just me
[23:28:58] <XXCoder> I left ubuntu when they added call home software on any and all searches you do on pc
[23:29:07] <XXCoder> including local files
[23:29:28] <somenewguy> and giant hard to customize icons on thelft, and re-arranged the settings menues as well as moving the damn buttons from top right to top left
[23:29:40] <XXCoder> somenewguy: try xbuntu
[23:29:52] <somenewguy> not that one side is better than the other, but swapping a fundamental layout item like that for 0 good reason is not a good sign about a projects aim
[23:30:00] <somenewguy> I am on arch now
[23:30:26] <somenewguy> although it has turned out to be a touch too tricky to keep running 100%, so I have a debian partition just in case lol
[23:30:40] <somenewguy> but now that I have oracle VM up and running, I haven't booted into that in a while
[23:30:53] <somenewguy> I have a linuxcnc VM that has heeksCAD/CAM running in it, and life is good
[23:31:00] <somenewguy> slic3r is working in arch again, so I can do all the things!
[23:36:59] <anarchos> hmm
[23:37:10] <anarchos> i don't even know how to tell if it's going to work
[23:37:24] <anarchos> can i see somehow if linuxcnc is talking to my controllers?
[23:39:52] <somenewguy> what is ur controller?
[23:40:10] <anarchos> well, keling 4042D
[23:40:20] <anarchos> well, it's the chinese version that keling rebrands
[23:40:24] <anarchos> so exactly the same
[23:41:34] <somenewguy> ok
[23:41:43] <somenewguy> so go to the menu and launch stepconf
[23:42:01] <somenewguy> this will basicly hold your hand thru setting up your configuration files
[23:42:07] <somenewguy> namely the .hal and .ini files
[23:42:16] <anarchos> ah, cool
[23:42:35] <somenewguy> you can pick from teh drop down list ur controller, and it will pre-select a bunch of settings that SHOULD be good enough to get yo ustarted
[23:42:41] <somenewguy> your estop works right ?
[23:43:05] <anarchos> ya
[23:43:12] <anarchos> hehe
[23:43:21] <somenewguy> cool, cause near the end of the stepconf wizard it will let you try and jog ur axis
[23:43:46] <somenewguy> so you will know quick if its working
[23:44:19] <somenewguy> basically it will take the default configureaton packed w/ linuxCNC, and copy it to ur desktop w/ your changes added to it, and from there on that little folder contains everything that makes your machine your machine
[23:46:27] <somenewguy> welcome back
[23:47:16] <somenewguy> forgot to mention, you shoudl do a latency test prior to doing stepconf
[23:48:13] <somenewguy> if u aren't already aware, that will just check how good ur computer is for running a cnc, checks how quickkly it can actually control its outputs. run the latency test, it suggests abusing ur computer, browse the web, watch some youtube, etc etc to geta worst case value
[23:48:24] <somenewguy> that value will llet you set ur max settings in stepconf
[23:52:29] <anarchos> yeah i did that
[23:52:37] <anarchos> got a max jitter of 14k
[23:52:45] <anarchos> is that good/bad? :P
[23:54:14] <somenewguy> i can never remember
[23:54:21] <somenewguy> a quick goolg will tell you
[23:54:38] <somenewguy> do you have a graphics card or integrated?
[23:55:01] <anarchos> If your "Max Jitter" number is less than about 15-20 microseconds (15000-20000 nanoseconds), the computer should give very nice results with software stepping
[23:55:06] <anarchos> woohoo
[23:55:16] <somenewguy> nice, then ur all set
[23:55:39] <anarchos> i believe it's has integrated graphics
[23:55:48] <somenewguy> normally that makes for really bad jitter
[23:55:51] <somenewguy> but since ur fine, no worries
[23:57:03] <anarchos> i didn't really do much, tho, they say to try and max it out, but since it has no network connector all i could do was load a bunch of stuff at once and move windows around
[23:58:17] <somenewguy> ur probably fine, but let it run for as long as you canbe bothered to just to be sure
[23:59:07] <somenewguy> my pc had an issue like every 18 minutes or so there would be a big jump in jitter, slapping a trash video card in fixed it
