[03:40:07] <Loetmichel> mornin'
[03:40:36] <archivist> moaning
[03:44:05] <Loetmichel> <. looking at the cnc mill.. that can take a while... and i need to make a second sheet... ->
http://www.cyrom.org/palbum/main.php?g2_itemId=15193
[03:45:16] <Loetmichel> remote work is so much quieter ;-)
[08:32:28] <tjtr33> hey i think today is IchGuchLive's last day on job, and he's relocating somewhere w/o inet. so this is his last day here too.
[08:32:34] <tjtr33> Plz remember all his videos and he works hard to help people.
[08:32:35] <tjtr33> Thanks IchGuckLive!
[08:46:24] <EW57> Good morning all! I'm a green as can be regarding linux/linuxcnc, but I've managed to get ubuntu 10.04 & linuxcnc loaded & am currently trying to fumble my way through some basic hal instructions from the command prompt. The immediate goal is to be able to use halmeter with a 5i25/7i85S to read rotary encoder position & I'm looking for some instruction on accessing the correct addresses/pins for encoder 0 on the 7i85S
[08:46:52] <Loetmichel> hrmpf... thanks, HP... they have changed panels and electronics of their 24" led monitors in the series... now i have to drill our enclosures again and then have to make a new measurement... ->
http://www.cyrom.org/palbum/main.php?g2_itemId=15196
[08:46:59] <Loetmichel> ... and thats for 30 pieces
[08:51:13] <CaptHindsight> Loetmichel: did they change the actual model/part number for the monitors or just suddenly start making them with those changes?
[08:56:45] <Loetmichel> cradek: same part numer, differen revision
[08:57:00] <Loetmichel> and even other manufacturer of the panel7electronics
[08:57:32] <Loetmichel> the old ones have samsung, tne new ones lg
[08:57:38] <Loetmichel> CaptHindsight
[08:58:30] <CaptHindsight> that's the gamble with devices like that, you never know when they will change them
[08:58:50] <Loetmichel> CaptHindsight: but ypu dont see the revision numer when buying them
[08:58:55] <Loetmichel> so its "surprise, surprise"
[09:00:01] <CaptHindsight> good to know HP does that
[09:01:09] <Loetmichel> the drilling new mounting holes is a nuissance
[09:01:33] <Loetmichel> but the new emi measurements and-documentation/grant from german authority is the expensive part
[09:37:21] <pcw_home> EW57: 7I85S manual should show correct encoder number for a config that has the 7I85S as the first daughtercard
[09:37:23] <pcw_home> (say 5i25_7i85Sx2.bit)
[09:40:54] <Benjamin23> ???
[09:41:26] <Benjamin23> I'd like to pester the powers that be for knowledge about controllers
[09:42:19] <jdh> ask and ye might receive.
[09:51:06] <Benjamin23> alright. I'm considering, for the start, understanding it will probably not be the greatest, either the CNC3040 or CNC 6040
[09:51:29] <Benjamin23> I'm under the impress the included cheap chinese controller is shit, and should be replaced with a better one
[09:51:50] <Benjamin23> I see there are several CNC controllers available, and using USB ones are to be avoided
[09:54:48] <cpresser> Benjamin23: for starters, you only need a PC with a 'real' parallel-port. and some wires to hook it up to the stepper-drivers
[09:56:03] <cpresser> Benjamin23: the inside of such a simple control may look like this:
http://imgur.com/j8MYJWh
[09:56:33] <cpresser> Benjamin23: ist a breakout-board for the parallel-port connector; some PSU and the drivers. thats it. only thing left ist to boot-up linuxcnc :)
[09:57:13] <Benjamin23> I've been reading about micro stepping, and will test for latency and whatever else needed for precision stepper control.
[09:57:48] <cpresser> http://www.micromo.com/microstepping-myths-and-realities
[09:58:02] <Benjamin23> cpresser: is there a schematic for the stepper drivers?
[09:59:19] <cpresser> Benjamin23: just buy them off ebay. they are cheap. no use in building them yourself (at least thats my opinion)
[10:00:16] <Benjamin23> I like to build stuff, and tend to have better engineering and manufacturing processes then most of the shit made in china
[10:00:53] <Benjamin23> cpresser: thanks for the links about microstepping. and it makes sense
[10:01:07] <cpresser> it all depends on budget and time :)
[10:01:39] <Benjamin23> I summize that if I need higher resolution, I can build a gear drive system to increase torque, resolution, obviously at the cost of speed
[10:02:04] <cpresser> basically yes. at least with steppers
[10:02:33] <cpresser> you can build a servo system, which is more complicated and expensive :)
[10:03:20] <cpresser> but this doesnt make that much sense with a chinese CNC6040
[10:04:06] <Benjamin23> no it doesn't, but it'll do the job until economics prove otherwise
[10:05:50] <cpresser> the mechanic parts will have play and backlash one order of magnitude higher than your theoretical stepper resolution
[10:06:15] <cpresser> the machine will bend when high cutting forces are applied
[10:08:19] <Benjamin23> got. good enough I think. I've been working on some 2D models, but rather useless until I see what is on a screen compared to what is actually milled
[10:13:30] <CaptHindsight> Benjamin23: one of the problems I always see wit the cheap 3040's and 6040's is the lack of proper ballscrew support
[10:13:56] <Benjamin23> I have zero idea what a ballscrew support is
[10:14:14] <CaptHindsight> I haven't found one yet that has nuts on the ends for setting the bearing preload
[10:14:25] <CaptHindsight> Benjamin23:
http://machinedesign.com/linear-motion/importance-ballscrew-end-fixity
[10:14:33] <Benjamin23> ah, that looks pretty important
[10:15:37] <CaptHindsight> all the ones I have gotten had no way of adjusting the preload unless you used shims or modified the screws and supports
[10:16:11] <CaptHindsight> they usually show up with up to 1mm of lash
[10:17:13] <CaptHindsight> some use a spring or lock washer between the bearing and screw, this is ok if there is no load or only used at low speeds
[10:18:06] <CaptHindsight> but if it's doing and cutting the forces will compress the spring or washer creating play or lash
[10:18:17] <CaptHindsight> and/any
[10:21:12] <CaptHindsight> http://machinedesign.com/site-files/machinedesign.com/files/archive/motionsystemdesign.com/images/fixed-end894.jpg all the cheap routes I've seen don't have that nut on the end of the ballscrew, they cut the screw to be about flush with the outside of the bearing and hope it stays out
[10:21:19] <CaptHindsight> out/put
[10:24:14] <CaptHindsight> Benjamin23: several also have arrives with crunchy linear bearings, so you have to take it all apart, clean and relube
[10:24:15] <Benjamin23> interesting. Looks like I'll have mill out some better parts for the CNC machine itself
[10:24:55] <CaptHindsight> I'll be back after coffee (too many typos)
[10:25:05] <Benjamin23> alright. thanks for the info
[10:25:56] <tjtr33> i just wrote a harangue to taiwan about them using the timing belt pulley as the bearing pre-load, cant service and not disturb bearing
[10:26:21] * Loetmichel just killed a circular saw blade... in 40cm cut of 4mm aluminium...
[10:26:30] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=15199&g2_imageViewsIndex=1
[10:27:02] <Loetmichel> ok, the while saw was just 40 eur, but still thats a bet less than expected cutting distance ,-9
[10:27:25] <Loetmichel> http://www.ebay.de/itm/111173391676
[10:27:30] <Loetmichel> whole
[10:41:02] <Benjamin23> I've never seen a saw blade that small
[10:41:11] <Benjamin23> what do they use it for on CNC?
[10:42:25] <SpeedEvil> Benjamin23: slitting stuff
[10:43:00] <SpeedEvil> Loetmichel: did that break the teeth off?
[10:43:09] <SpeedEvil> Loetmichel: you diddn't put it on backwards?
[10:45:40] <Loetmichel> no
[10:46:08] <Loetmichel> i think one tooth got noose, embedded itseldfin the aluminium and destroyed the others
[10:46:15] <SpeedEvil> hmn
[10:46:27] <Loetmichel> because it cut well untiol 5cm before the endm and then all of a sudden: notong
[10:46:36] <SpeedEvil> plausible - assuming your aluminium doesn't have an inclusion
[10:46:38] <Loetmichel> as i lifted it and looked it looked klike this
[10:47:29] <Loetmichel> Benjamin23: i use it to cut the aluminium sheet si mill
[10:47:50] <Loetmichel> but you can use it to make cuts horizontally in the workpiece
[10:48:11] <Loetmichel> i made one in 80mm for a older mill:
[10:48:37] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=5471
[10:48:41] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=5474
[10:48:46] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=5468
[10:48:59] <Loetmichel> ... and yes, i stood behind the gantry as it had run.
[10:49:01] <Loetmichel> ;-)
[11:00:19] <FinboySlick> Loetmichel: How to turn your mill into a deadly shuriken-throwing ninja.
[11:07:21] <SpeedEvil> It's much faster than a end-mill, in some circumstances
[11:08:34] <PetefromTn_> I had a slitting saw arbor for the RF45 that I used occasionally.
[11:08:44] <PetefromTn_> Worked pretty well if you have the right blade.
[11:09:07] <PetefromTn_> I tried to cheap out and buy a small circular saw blade for it and that did not work well at all.
[11:09:29] <PetefromTn_> They sell quality slitting saw blades for reasonable prices and they are ground for the cut properly
[11:09:47] <syyl_> love slittting saws :D
[11:10:05] <syyl_> some people realy get scared when they see em used
[11:10:35] <PetefromTn_> Its not a bandsaw but it does have its uses and for a nice clean slot they are worth it.
[11:10:49] <PetefromTn_> Anyone ever seen or made one of these?
http://www.naffziger.net/blog/2008/07/05/the-alton-brown-flower-pot-smoker/
[11:11:01] <PetefromTn_> I am thinking about getting some parts and making one this weekend LOL
[11:11:31] <FinboySlick> The 'pot-smoker' bit at the end is a bit ambiguous until you click the link.
[11:11:43] <PetefromTn_> LOL yeah I saw that.
[11:12:01] <PetefromTn_> I have a close friend in Atlanta that I speak to all the time on the phone.
[11:12:23] <PetefromTn_> He has been telling me all about his delicious brisket and pork smoking
[11:12:31] <PetefromTn_> adventures in smoking basicallly LOL
[11:12:44] <PetefromTn_> turns out this is what he is using to smoke all that meat.
[11:12:54] <PetefromTn_> After looking into it I think it is a pretty cool idea.
[11:13:09] <PetefromTn_> Apparenlty he can even smoke an entire turkey in his.
[11:13:49] <PetefromTn_> I kinda look at it like it would be fun to try it and I would make a nice custom fabricated stand for the pot so it is not sitting on the damn floor and I have to bend down to work on it.
[11:14:16] <PetefromTn_> If you look online there are tons of them out there people have made.
[11:14:34] <PetefromTn_> some use the hotplate element and some use charcoal etc.
[11:14:45] <PetefromTn_> I kinda like the electric route.
[11:14:47] <FinboySlick> I imagine this is where Big Green Egg got their inspiration.
[11:14:54] <PetefromTn_> could be.
[11:15:08] <PetefromTn_> Those are cast iron I think..
[11:15:25] <FinboySlick> The inside is ceramic.
[11:15:26] <PetefromTn_> but the pots are inexpensive and they appear to work quite well.
[11:15:38] <PetefromTn_> My friend has made all sorts of smoked meat in his.
[11:15:58] <PetefromTn_> every time I talk to him he is braggin about how good that smoked meat he made last night was.
[11:16:18] <PetefromTn_> I was so surprised when he told me that this is what he has been cooking it all in LOL
[11:20:25] <PetefromTn_> http://lifehacker.com/5601265/wknd-bp340-build-the-cadillac-of-diy-flower-pot-smokers-to-bbq-in-style this one looks nice.
[11:29:09] <PetefromTn_> http://z12projects.blogspot.com/2010/07/little-blue-egg.html cool!
[11:55:16] <PetefromTn_> gotta go meet my wife for lunch talk to you guys later CHEERS!!
[12:16:06] <shaun413> hello
[12:16:13] <shaun413> http://www.windpowersports.com/images/accessories/winders/rev-standard-handles.png
[12:16:20] <shaun413> Im trying to make something like this ^
[12:16:27] <shaun413> thought id ask here if anyone had any ideas how?
[12:17:07] <mozmck> bend a piece of pipe and put foam rubber on it.
[12:17:16] <shaun413> what type of pipe?
[12:17:39] <mozmck> Looks like it is probably stainless or chrome plated steel?
[12:17:54] <shaun413> pipe? or solid?
[12:18:20] <mozmck> I doubt it's solid - too heavy
[12:18:27] <shaun413> looks like 3/8in stainless tube
[12:19:32] <mozmck> 3/8" sounds a little small to me - I would think more like 3/4"
[12:19:43] <shaun413> it is 3/8
[12:19:45] <mozmck> ok
[12:19:45] <shaun413> found the specs
[12:20:18] <shaun413> where could In get that foam? and how would I bend it? and the endcaps lol
[12:20:34] <mozmck> The end caps look like something you can get at an automotive store
[12:20:41] <shaun413> hmm?
[12:21:28] <mozmck> I don't know how soft the foam rubber is, and I'm not sure where you can get it.
[12:21:40] <shaun413> like fishing pole grip
[12:22:00] <mozmck> vacuum hose caps, or maybe shipping tube ends or something.
[12:24:57] <shaun413> anyway to easily smooth out steel rod ends
[12:24:59] <shaun413> without a lathe?
[12:28:10] <shaun413> how could I bend the angle smooth?
[12:46:04] <IchGuckLive> hi all B)
[12:46:28] <Klaus-Krefeld> Hi :-)
[12:48:42] <IchGuckLive> shaun413: dont you think that is a wing shaped element
[12:51:43] <CaptHindsight> IchGuckLive: Happy retirement day to you!
[12:52:05] <IchGuckLive> first non workday its birthday today
[12:53:42] <CaptHindsight> IchGuckLive: so what's the new plan?
[12:54:05] <shaun413> what do you mean IchGuckLive ?
[12:55:11] <IchGuckLive> CaptHindsight: going offline in the outback for 5 years
[12:55:44] <IchGuckLive> shaun413: i looked at the png and its not round i think its more wing format as a savonius shaped
[12:55:53] <shaun413> ok?
[12:56:05] <CaptHindsight> IchGuckLive: still in Germany or off to a small island in the south Pacific?
[12:57:01] <IchGuckLive> CaptHindsight: not far from here but in a deep valey with no"civilisation as a ranger like job
[12:57:18] <shaun413> i guess ill just hav3e to buy them :/
[13:04:39] <shaun413> grrrr
[13:08:09] <CaptHindsight> http://www.automationtechnologiesinc.com/products-page/kl-stepper-drivers/kl-4030-24-40vdc-3-0a-microstepping-driver whats the max length of the cable from drive to motor with these?
[13:12:28] <SpeedEvil> Depends on the cable.
[13:12:31] <SpeedEvil> A kilometer?
[13:13:13] <SpeedEvil> Keep the resistance of the cable under .1 ohms or so - one way.
[13:13:50] <SpeedEvil> http://cs.nju.edu.cn/yangxc/dcc_teach/wire-resistance.html
[13:14:44] <SpeedEvil> So one square millimeter cable - of the order of 10m
[13:22:18] <anonimasu> hm..
[13:22:32] <anonimasu> did anyone read the question i posted before about adjusting height of a torch while in cut?
[13:22:42] <anonimasu> (manually)
[13:27:46] <IchGuckLive> anonimasu: just a joypad or pyvcp button to trigger the THCUD component
[13:27:54] <IchGuckLive> i did that lots
[13:28:15] <IchGuckLive> but its a miss on ARC ok
[13:28:28] <IchGuckLive> you will get lots of arc shut downs
[13:29:07] <FinboySlick> http://www.hookbag.ca/product/HIS0IKHEN/ I like the little blue corner in the order form.
[13:29:25] <FinboySlick> "Free Shipping"
[13:29:51] <anonimasu> my oxyfuel dosent arc-out :D
[13:30:32] <IchGuckLive> ok
[13:30:45] <IchGuckLive> anonimasu: do you fot the thcUD comp inside
[13:31:09] <anonimasu> no I tried to tweak the values of the axis with offset..
[13:31:10] <anonimasu> :/
[13:31:11] <anonimasu> brb..
[13:32:33] <IchGuckLive> use the thcud comp and you are fine
[13:32:35] <CaptHindsight> SpeedEvil: it's the self-adjustment of the drive I'm wondering about, it's not just the resistance of the wires
[13:33:20] <SpeedEvil> CaptHindsight: the self-capacitance of the windings will typically be quite large and dominate all reasonable wires
[13:34:43] <IchGuckLive> anonimasu: hit my nick
[13:35:37] <CaptHindsight> SpeedEvil: they have a DSP that senses current and voltage, I'm not sure what range it has or what they use for an algorithm for idle current reduction or impedance matching
[13:36:20] <CaptHindsight> SpeedEvil: it's more how far had anyone gone with one without issues
[13:38:10] <CaptHindsight> I also don't know how they handle back emf from the motor
[13:38:36] <CaptHindsight> that's the problem with these discount drives
[13:42:09] <Jymmm> When doing electro-etching, do they HAVE to be dissimilar metals?
[13:45:01] <CaptHindsight> doesn't the similar metal build up on itself?
[13:45:09] <CaptHindsight> nevermind
[13:45:14] <CaptHindsight> you said etch
[13:45:19] <Jymmm> =)
[13:45:29] <CaptHindsight> so you are removing metal?
[13:45:36] <Jymmm> CaptHindsight: Eh, same thing, just reverse polarity =)
[13:45:46] <Jymmm> yes, removing
[13:48:49] <CaptHindsight> you have to look at the chemistry to decide
[13:49:12] <CaptHindsight> what will happen based on your choice of metals
[14:59:47] <jdh> gold and platinum
[15:03:28] <archivist> monel metal
[15:31:25] <CaptHindsight> ends up back EMF killed the TB6560
[15:41:35] <Jeebiss> hey guys
[15:41:48] <Jeebiss> im am just starting to dive into the cnc world
[15:42:04] <Jeebiss> and I am in process of constructing a miniature cnc machine
[15:42:29] <Jeebiss> I was wondering if someone could tell me how linuxcnc is supposed to communicate to my completed machine.
[15:42:40] <Jeebiss> I dont fully understand that part.
[15:45:47] <CaptHindsight> Jeebiss: linuxcnc runs on a PC, the cnc machine has motors, the motors have drives....
[15:46:21] <Jeebiss> Right. I understand that part.
[15:46:34] <Jeebiss> But how do I connect my pc to the motor drivers?
[15:46:42] <CaptHindsight> Linuxcnc sends signals to the drives for them to move (how much and how fast)
[15:47:06] <CaptHindsight> what kind of motors do you have? steppers?
[15:47:22] <Jeebiss> yep
[15:47:34] <CaptHindsight> do you have stepper drivers yet?
[15:47:43] <Jeebiss> kind of
[15:47:54] <Jeebiss> i plan to abuse these two floppy drives
[15:47:57] <CaptHindsight> for instance
http://www.automationtechnologiesinc.com/products-page/kl-stepper-drivers/kl-4030-24-40vdc-3-0a-microstepping-driver
[15:48:01] <Jeebiss> and i also have a couple easydrivers if all else fails
[15:48:04] <CaptHindsight> ah ok
[15:48:24] <Jeebiss> i am talking real small scale at the moment
[15:48:24] <CaptHindsight> you can use a parallel port to send STEP and Direction
[15:48:28] <Jeebiss> just to see if i want to delve into this further
[15:51:10] <Jeebiss> So its possible to use the parallel port as an interface with linuxcnc?
[15:51:20] <Jeebiss> Is that fairly straight forward?
[15:51:28] <CaptHindsight> http://linuxcnc.org/docs/html/common/images/whatstep1.png
[15:51:55] <CaptHindsight> yes, as I mentioned you can use a parallel port to send STEP and Direction to the stepper driver
[15:52:01] <Jeebiss> Ah okay
[15:52:56] <CaptHindsight> you just need a PC fast enough to send the step pulses at the rate you want the motors to move
[15:54:13] <CaptHindsight> Jeebiss:
http://linuxcnc.org/docs/html/common/user_intro.html
[15:54:25] <CaptHindsight> start here and look it over
[15:54:34] <Jeebiss> What aspect of a computer would determine that speed?
[15:54:34] <Jeebiss> The cpu?
[15:56:22] <SpeedEvil> No, the case.
[15:56:25] <SpeedEvil> Paint is important.
[15:56:56] <SpeedEvil> Speed is a complex thing - all the active parts can impact speed on given tasks.
[15:57:16] <SpeedEvil> Some may be limited by CPU, some by RAM quantity or speed, some by GPU, some by storage
[15:57:25] <SpeedEvil> Networking or IO
[15:57:27] <CaptHindsight> Jeebiss:
http://linuxcnc.org/docs/html/install/Latency_Test.html
[15:57:59] <SpeedEvil> Oh - /me missed the word 'that'.
[16:00:11] <dr0w> I like hotrod red, personally
[16:03:07] <CaptHindsight> Jeebiss: LinuxCNC does not require bleeding edge hardware. Lots of people use $5-25 used PC's
[16:04:15] <Jeebiss> Sorry, internet took a dive
[16:05:03] <Jeebiss> CaptHindsight: I am going to read over the links you sent me, thanks!
[16:05:57] <CaptHindsight> just spotted this
http://www.generalmechatronics.com/en/linuxcnc
[16:08:49] <CaptHindsight> Jeebiss:
https://www.sparkfun.com/products/10267 use Step and Direction
[16:10:17] <CaptHindsight> Jeebiss: you might also want an isolated breakout board for the parallel port so you just fry the board vs the parallel port while you're learning

[16:14:51] <zeeshan> :{
[16:15:51] <jdh> yeah, become a sheep herder.
[16:16:20] <zeeshan> haha
[16:16:28] <zeeshan> i did a tensile test on some smp today
[16:16:37] <zeeshan> metals have a linear elastic region..
[16:16:39] <zeeshan> this damn smp

[16:18:02] <zeeshan> im a hardcore mech guy
[16:18:19] <zeeshan> reading about polymers is like.....
[16:18:21] <zeeshan> BORIGN!
[16:18:33] <zeeshan> i need to talk to my supervisor
[16:19:17] <CaptHindsight> maybe a nice project on why right handed threads are better than left handed
[16:19:28] <Tom_itx> they aren't :)
[16:20:01] <dr0w> they are when you've got a cheater bar and don't know any better. ;)
[16:20:13] <Tom_itx> why do the numbers on a clock go clockwise?
[16:20:16] <CaptHindsight> and the arguments that ensue
[16:20:20] <Tom_itx> they should turn the other way
[16:20:22] <dr0w> is anyone running linuxcnc on rPi?
[16:20:48] <CaptHindsight> dr0w: some are using the BBB
[16:21:01] <zeeshan> left hand threads are great
[16:21:07] <zeeshan> for something that spins clockwise :p
[16:22:21] <SpeedEvil> https://www.youtube.com/watch?v=bCsg5pQimWI - related to metal elasticity.
[16:22:30] <SpeedEvil> Nutter makes a pulsejet with hydroforming
[16:22:37] <CaptHindsight> hex socket vs hex heads on bolts
[16:25:20] <zeeshan> SpeedEvil: you mean plasticity? :)
[16:29:09] <CaptHindsight> wow, he wears a tie in the shop
[16:29:30] <CaptHindsight> and he still has a face
[16:30:54] <dr0w> ahh.. the beaglebone looks pretty cool
[16:33:36] <CaptHindsight> heh, he sets his truck bed ablaze
[16:35:18] <CaptHindsight> https://www.youtube.com/watch?v=D5_ogU4Jzt4&list=UUp68_FLety0O-n9QU6phsgw seems safe :p
[16:43:12] <syyl_> what should even go wrong? :D
[16:43:31] <syyl_> but always remember - flames make small, black and crunchy
[16:49:11] <SpeedEvil> CaptHindsight: the video I linked is one of his safest videos
[17:13:05] <anarchos2> what's the best way to set up my Z axis?
[17:13:41] <anarchos2> i have about 8" of travel, should I set the home (all the way at the top) position to 0.0 and have it travel down to -8?
[17:14:03] <anarchos2> or would it make more sense to have home at -8 and it travel to 0?
[17:17:41] <zeeshan> machine home is usually set to a region
[17:17:44] <zeeshan> where no crash can happen
[17:18:05] <zeeshan> so you want it furthest away from table
[17:20:54] <anarchos2> ok
[17:21:22] <anarchos2> so i have it so when z is at the very top, furthest away from the table, it's at 0.0. then as it travels down it goes into negatives
[17:21:57] <anarchos2> down to -8.0, which is pretty much where my spindle hits the table
[17:50:47] <Klaus-Krefeld> bye good night ;-)
[18:33:05] <cpresser> anarchos2: make sure you have the directions of the axis correct. there is a right-hand-rule for the orientation
[19:13:37] <MC500> I have a question about a Fanuc 21M controller are there any general CNC channels on any of the IRC servers?
[19:14:02] <CaptHindsight> http://www.bevelcutting.com/blog.html myCNC software? It must be closed source but I've never heard if it before.
[19:16:15] <CaptHindsight> MC500: you might do better posting that on one of the cnc forums
[19:17:01] <CaptHindsight> people only get upset in here if you ask about Mach :p
[19:53:29] <CaptHindsight> is there a way to keep an axis from being jogged manually if another axis is within a set range of travel?
[19:59:28] <CaptHindsight> this could be like a soft bounding box so that say X can't be jogged unless Z is above a certain height
[20:01:57] <SpeedEvil> Did crunching noises happen?
[20:02:45] <CaptHindsight> heh, no just came across an application where this might help to prevent user error
[20:06:43] <CaptHindsight> or an open loop stepper system where one axis dies/locks and you want to prevent a crash
[20:27:27] <CaptHindsight> maybe ClassicLadder with some extra extra limit/position switches for feedback if something doesn't actually move when commanded
[20:28:55] <XXCoder1> hey
