[01:45:42] <jdhNC> hey! somebody paid me to make them something.
[01:47:15] <skunkworks> I think I made about 3 pounds of aluminum shavings tonight
[01:47:36] <jdhNC> I'm working toward aluminum shavings
[01:47:38] <skunkworks> ok - probaby not that much - but the whole machine is covered

[01:57:44] <toastydeath> jdhNC, what hourly rate did you quote them
[02:01:50] <jdhNC> 'free'
[02:02:30] <toastydeath> ?
[02:03:14] <jdhNC> well, by paid, he sent me a restaurant gift card
[02:03:35] <toastydeath> ah
[02:03:43] <jdhNC> he wanted some plastic thingies cut, I told him to just give something to someone sometime for me.
[02:05:50] <toastydeath> xlnt!
[02:06:03] <jdhNC> http://www.artichoke.org/hosethings.pdf
[02:06:13] <toastydeath> oh cool
[02:06:35] <toastydeath> how'd you hold it, if you don't mind my asking? double sided tape?
[02:07:09] <jdhNC> clamp the stock down, hold it by hand for the last part
[02:07:18] <toastydeath> hahah
[02:07:21] <Valen> dodgy lol
[02:07:21] <toastydeath> i approve
[02:07:36] <Valen> I'd just cut it out of bar then trim to length
[02:08:01] <toastydeath> still have to hold it
[02:09:43] <jdhNC> http://www.artichoke.org/NewImprovedHoseThings.pdf
[02:10:02] <toastydeath> that's definately a double sided tape job
[02:10:08] <jdhNC> those were the latest revs, guess he felt bad about me making them again after he changed his mind
[02:10:33] <toastydeath> how'd you mill the ellipse
[02:10:48] <toastydeath> macro or cam?
[02:11:32] <jdhNC> autocad + cut2d

[02:13:38] <jdhNC> http://www.artichoke.org/loophose.jpg
[02:13:55] <jdhNC> the oval ones are on the smaller hose
[02:15:10] <toastydeath> nice
[02:22:27] <atom1> that's one i must say i've never drawn in my cad package
[02:22:31] <Valen> heh friend wants me to make bits for his rebreather too lol
[02:23:14] <Valen> you clamp the excess stock in the vice then mill was my method
[02:24:12] -!- mhaberler [mhaberler!~mhaberler@extern-182.stiwoll.mah.priv.at] has joined #emc
[02:24:29] <atom1> jdhNC, what's the blend radius of the two?
[02:24:59] <jdhNC> en englese por favore?
[02:25:17] <atom1> i'm looking at the modified drawing
[02:25:21] <atom1> just playing around
[02:25:39] <toastydeath> jdhNC, consider making yourself some MDF vice jaws
[02:25:41] <atom1> the oval with the ajacent hole
[02:25:46] <toastydeath> if you are going to be making a lot of bizarre plastic shapes
[02:25:52] <toastydeath> and also invest in double sided tape
[02:26:01] <atom1> soft jaws are invaluable
[02:26:19] <jdhNC> toasty: yeah, that would be nice.. I'd like to have a jig so I could remount them and radius the cut edges
[02:26:33] <atom1> on stuff that used them, we kept them as part of the setup
[02:26:38] <toastydeath> just make a bunch of vice jaws that are really thick
[02:26:45] <atom1> yup
[02:26:50] <toastydeath> like, 3" long each vice
[02:26:58] <atom1> 6
[02:27:02] <atom1> to fit a kurt vise
[02:27:03] <toastydeath> so you just slap them on your vice, and mill the negative
[02:27:09] <toastydeath> atom1, i mean the other dimension
[02:27:29] <toastydeath> so that you have a 6x6 surface
[02:27:31] <jdhNC> the fillet on the oval/circle was .125 on the intersection
[02:27:31] <toastydeath> by however tall
[02:29:20] <jdhNC> draftsight wouldn't fillet it, I had to load it in autocad

[02:45:17] <jdhNC> what cad cam?
[02:45:49] <atom1> smartcam
[02:45:58] <atom1> it's pretty old but works good
[02:50:10] <atom1> http://tom-itx.dyndns.org:81/~webpage/temp/test.jpg
[02:54:39] <elmo40> atom1: looks nice :)
[02:55:31] <atom1> just bored i guess. i'd never drawn an elipse with it
[02:55:41] <atom1> but it's real easy
[02:56:07] <jdhNC> looks good to me
[02:56:49] <jdhNC> those parts were actually open on the small end, I forgot that in the original drawing.
[02:57:33] <jdhNC> personally, I use slices of mountain bike inner tube where he is using those things
[02:57:35] <atom1> the circular one is in the drawing
[02:57:42] <atom1> heh
[02:57:45] <atom1> probably easier
[02:58:10] <elmo40> have you seen the free 2D app from the makers of soldi works? http://www.draftsight.com/learning/
[02:58:28] <jdhNC> rebreather divers are often neat-freaks, it's a good habit
[02:58:47] <atom1> i've had this package probably 15 yrs or so
[02:58:56] <jdhNC> I use draftsight most of the time, it's less resource hoggy than autocad
[02:59:07] <atom1> it's got posts for alot of machines and you can customize your own
[02:59:08] <jdhNC> but, it won't let you fillet an ellipse/oval
[02:59:27] <elmo40> fillet an ellipse? interesting
[02:59:38] <atom1> you gotta be careful how you select the elements or it will come out different
[03:00:02] <atom1> it will favor the first selected side or you can enter a 'best solution' mode
[03:02:03] <atom1> instead of drawing the perimeter, i did a wall offset of the 2 inner elements of .15
[03:02:17] <Gensor> Hello - Is there a way to ftp download or batch download http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/
[03:02:19] <atom1> that's why it has all the arc/line segments listed
[03:03:35] <jdhNC> Gensor: wget
[03:03:56] <Gensor> wget
[03:04:13] <Gensor> uhm.... wget where
[03:04:44] <Gensor> you mean I can anonymous ftp in and get the data?
[03:04:47] <elmo40> open a text file and past in the links.
[03:04:55] <elmo40> then use wget -I download.txt
[03:04:59] <elmo40> and it will download them all
[03:05:07] <elmo40> -i not -I, sorry
[03:05:27] <elmo40> but what for?
[03:05:43] <Gensor> strip urls and for easier reading
[03:05:45] -!- Connor_CNC has quit [Read error: Connection reset by peer]

[03:06:09] -!- Connor1 [Connor1!~billy@] has joined #emc
[03:06:40] <atom1> jdhNC what's the center distance on between the 2 circles in the lower part?
[03:07:30] <jdhNC> I think the ID's are .25" apart
[03:08:29] <atom1> the lower part
[03:10:01] <Gensor> elmo- Im using windows, how do i view the webpage and copy the hyperlinks... all I get is the text as displaced
[03:10:22] <atom1> get winftp
[03:10:23] <jdhNC> which one is the lower part?
[03:10:32] <atom1> the 'earring'
[03:10:56] <elmo40> Gensor: click the link you posted and it should open in firefox
[03:11:25] <jdhNC> the big loop with the little pop-in loop? should be .25 unless I changed it by accident.
[03:11:41] <atom1> between hole centers?
[03:11:42] <atom1> naw
[03:11:54] <jdhNC> no between ID quadrants
[03:12:09] <jdhNC> .75 + .25 + .225
[03:12:53] <elmo40> Gensor: did it open?
[03:15:24] <jdhNC> elmo40: http://www.artichoke.org/pop-in-loop.dxf
[03:16:29] <elmo40> ok
[03:16:42] <elmo40> looks like a clip that holds a tube
[03:16:54] <jdhNC> it is a clip that holds a tube
[03:17:02] <jdhNC> hose actually
[03:17:11] <elmo40> same difference ;)
[03:17:59] <jdhNC> the big side goes on the rebreather loop hose, the small clip holds the air hose to the bail out regulator

[03:33:19] <jdhNC> I'd just get wget for windows
[03:33:40] <atom1> http://tom-itx.dyndns.org:81/~webpage/temp/test.jpg
[03:33:44] <atom1> ok, i'll stop
[03:34:02] <atom1> :)
[03:35:48] <jdhNC> next time, I'll send you his MS Paint sketches!
[03:36:02] <atom1> i'm just bored
[03:36:16] <atom1> and a bit rusty so i figured it was a good exercise
[03:36:21] <Valen> make me 32u4 breakout boards then ;-P
[03:36:27] <atom1> i have one
[03:36:35] <Valen> i said make *me*
[03:36:47] <atom1> http://tom-itx.dyndns.org:81/~webpage/boards/atmega32u4/atmega32u4_1.jpg
[03:36:56] <atom1> what's it worth?
[03:37:03] <Valen> lol not much ;->
[03:37:14] <Valen> I would have paid more to get them than the u2's I got
[03:37:30] <Valen> but i need to make a PCB anyway so not much of a win
[03:37:39] <atom1> i have maybe half dozen boards
[03:37:42] <atom1> i dunno
[03:37:56] -!- ve7it has quit [Remote host closed the connection]
[03:37:59] <Valen> they are pin compatible aren't they?
[03:37:59] <atom1> i think i have a new rev with that oscillator instead of the crystal
[03:38:06] <atom1> what?
[03:38:10] <Valen> the 2 and 4
[03:38:16] <atom1> i dunno
[03:38:23] <atom1> i have the pinout for this somewhere
[03:38:25] <elmo40> Gensor: hi
[03:38:32] <elmo40> Gensor: have you installed wget for win32 yet?
[03:38:32] <atom1> i doubt it since it has adc and more pins
[03:38:37] <Valen> what xtal you use?
[03:38:40] <atom1> iirc it's a 44 qfn
[03:38:49] <Valen> ahh i didn't notice
[03:38:50] <atom1> and the 2 is 32 tqfp
[03:38:56] <Valen> you can get the 4 in tqfp
[03:39:12] <atom1> yeah but it won't fit between .6" centers
[03:39:18] <atom1> for the 'dip' pinout
[03:39:26] <Valen> not easily no
[03:39:59] <atom1> i only soldered up that one to test the layout
[03:40:17] <Valen> farnell only has the u4 in tqfp which is bigger than I would have liked
[03:40:26] <atom1> yup
[03:40:36] <atom1> seems you can never get what you want from atmel
[03:40:48] -!- kljsdfhklj [kljsdfhklj!~ln@] has joined #emc
[03:41:01] <Valen> I do wonder if I should go back to PIC's
[03:41:02] <atom1> what do you need a u4 for?
[03:41:09] <Valen> ADC + USB + PWM
[03:41:28] <atom1> pendant?
[03:41:28] <Valen> basically making a synchronous buck LED driver with fancy bits
[03:41:45] <atom1> i think it might be too slow unless you use a txt lcd
[03:41:58] <Valen> ?
[03:42:05] <atom1> for a pendant
[03:42:12] <Valen> basically making a synchronous buck LED driver with fancy bits
[03:42:46] <Valen> as in a torch for making light
[03:43:17] <atom1> ok, enough for one day.
[03:43:48] <atom1> i did start a layout for the at90usb1287
[03:43:54] -!- Gensor has quit []
[03:44:11] <atom1> i put it on hold when they started obsoleting the at90xx parts
[03:44:50] <Valen> doesn't seem to have that much other than ram and flash going for it?
[03:45:15] <atom1> host
[03:45:19] <Valen> ahh
[03:45:29] <Valen> isnt the u4 host as well?
[03:45:34] <atom1> nope
[03:45:39] <atom1> just the 1286 1287
[03:45:57] <Valen> is thats whats on that atmel usb board thing?
[03:46:12] <atom1> not sure but probably
[03:46:32] <Valen> they really should make their products have some kind of sensible naming scheme

[13:47:06] <Paragon39> Hello All, Could this board be connected directly to the para port or would it require additional circuitry ie darlington or optocoupler? http://www.sigma-shop.com/product/63/eight-relay-board-ready-for-your-pic-avr-project-5v.html

[13:51:27] <archivist> documentation of the inputs is lamentable
[13:52:07] <awallin_> looks like there's a transistor there though...
[13:52:16] <awallin_> and it wants its own +5V supply
[13:52:44] <Paragon39> archivist: I agree not much to go on.
[13:53:47] <archivist> sure the relays provide the isolation, but we cannot say if the parport can drive it
[13:54:30] <archivist> I would get out some vero board and solder :)
[13:54:38] <Paragon39> awallin_: It appears to only require the paraport to drive the small transistors but it does not specify there current requirements.
[13:55:07] <Paragon39> Arrr just found this on the same site... http://www.sigma-shop.com/product/17/relay-unit-control-up-to-8-devices-using-your-pc-5v.html

[15:34:15] <wonko> oh, that's nifty though
[15:34:21] <wonko> not that i do much CNC anymore these days
[15:34:32] <Jymmm> And it sucks to be you for buying EMC instead of NetApp =)
[15:35:18] <wonko> eh, not me, client
[15:35:22] <wonko> i push netapp every chance i get
[15:35:27] <wonko> i've always liked netapp
[15:35:29] <Jymmm> wonko: Check out the LiveCD sometime if you're so interested =)
[15:35:32] <wonko> never touched emc much
[15:35:44] <wonko> the more i work with EMCs, the more i like netapps. :-D
[15:35:49] <wonko> Jymmm: i think i might, thanks!
[15:35:56] <Jymmm> Me too, especially since my friend works there and can get serious discounts =)
[15:36:05] <wonko> niiiiice
[15:36:10] <wonko> get a FAS2020 for home yet? :-D
[15:36:50] <Jymmm> Ha, too power hungry. But I am looking at a Promise NS6700 if the bastards ever release it in the US.
[15:38:01] <Jymmm> Even supports Amazon S3 replication
[15:38:09] <wonko> i can't see a FAS2020 being any worse than the monster Dell box i have for a fileserver now. :-D
[15:38:34] <Jymmm> At 6A idle, fsck that =)
[15:38:34] <wonko> oh, those look nice
[15:38:37] <wonko> i wonder what they'll cost
[15:38:41] <wonko> heh
[15:38:58] <Jymmm> It's looking like ~$1000 USD for the 6bay
[15:39:16] <Jymmm> I just hope it lives up to the hype
[15:39:55] <Jymmm> I should call them and see if I can get my hands on an eval unit
[15:39:57] <wonko> does it come with disks for that price or is that for a diskless config
[15:40:24] <Jymmm> I think diskless, can't get any specs out of them. Their focusing on the Thunderbolt version
[15:40:50] <wonko> good god this datasheet pdf is awful
[15:40:51] <Jymmm> yu can't beat 10GigE option that's for sure
[15:41:08] <Jymmm> err 10 Gbps
[15:41:42] <Jymmm> That's just obscene transfer rate for >$2000
[15:41:52] <Jymmm> err <
[15:42:49] <wonko> yeah, that's quite impressive
[15:42:51] <Jymmm> You could stream full Hd pr0n to the whole neighborhood with that!
[15:42:53] <wonko> i wonder what bittorrent client they use
[15:42:56] <wonko> heh
[15:42:59] <Jymmm> multiple channels!
[15:43:21] <Jymmm> it's a plugin
[15:43:50] <Jymmm> and they have a squeezebox plugin too (hawt damn)
[15:43:54] <wonko> i mean, i really don't care, so long as i can configure it to meet the requirements of the private tracker i'm on
[15:44:00] <wonko> oh, and the API can't suck
[15:44:32] <Jymmm> "requirements"? Not just a login?
[15:44:54] <Jymmm> who said anything about an API =)
[15:45:23] <wonko> yeah, can't use DHT or some other stuff
[15:45:33] <wonko> i use the transmission API quite heavily
[15:45:39] <wonko> wrote a bunch of apps that control transmission for me
[15:45:47] <Jymmm> oh, sounds like a grn monster
[15:45:51] <wonko> well, let me re-phrase that
[15:46:06] <wonko> half-finished a bunch of apps that will control transmission for me
[15:46:07] <wonko> :-D
[15:46:46] <wonko> hmm, the fact that it does time machine and itunes works very well for me as that's something i really wish my current fileserver provided
[15:47:05] <Jymmm> BT is so over rated and so easily getting busted. NNTP FTW
[15:47:17] <wonko> heh
[15:48:28] <Jymmm> 14yo has to pay $30K, 35yo gets $25K fine over 9 songs @ $0.99 each. Just not worth it
[15:49:35] <wonko> yeah, that's insane
[15:50:04] <Jymmm> Far cheaper to pay $20/mo for news and get it fast and secure
[15:50:35] <wonko> i really do need to get NNTP set back up

[16:57:14] <sarariman_seb_> Connor, having the home/limit switch at 0.0000 (HOME_OFFSET=0.0000) and the home position at 0.0001 (HOME=0.0001) means you won't be able to move to 0.0000
[16:57:30] <sarariman_seb_> that's why i suggested HOME_OFFSET=-0.001 and HOME=0.000 yesterday
[16:57:42] <sarariman_seb_> it'll make 0.000 be a valid place for you to move to
[16:58:39] <Connor> That's not what I did. The offset is in the -, home itself is 0.0001
[16:59:24] <Connor> For what ever reason, when EMC homes to 0 when coming from the negative side, it still carries a negative value with it even though the DRO reads 0
[17:01:56] <sarariman_seb_> do you mean if you put the home/limit switch at -0.001 and home at 0.000, after homing the DRO reads "-0.000"?
[17:02:16] <Connor> yes
[17:02:25] <Connor> and that causes a softlimit error
[17:02:48] <Connor> which then cancels the other homing sequences if they're still in process
[17:03:00] <sarariman_seb_> strange
[17:03:26] <Connor> btw, these values are in mm not inch.
[17:03:59] <cradek> you have a minimum soft limit of 0?
[17:04:25] <sarariman_seb_> Connor: yay, metric! :-)
[17:04:39] <Connor> Well.. I still set everything to inch. :)
[17:04:51] <cradek> your home position needs to be inside the soft limits, not on one of them
[17:04:55] <Connor> but the screws where metric, so, machine is in metric.
[17:05:52] <Connor> cradek: Yea.. that's what I'm finding.. I could write something that after it homes all the axis, it sends them back to 0,0,0
[17:06:00] <sarariman_seb_> cradek, you mean [AXIS_n]MIN_LIMIT must be > [AXIS_n]HOME?
[17:06:01] <cradek> if you want the machine to home at one extreme, and call it 0, set HOME=0 and MIN_LIMIT=-0.0001
[17:06:24] -!- IchGuckLive [IchGuckLive!~chatzilla@95-89-104-26-dynip.superkabel.de] has joined #emc
[17:06:25] <sarariman_seb_> and HOME_OFFSET can be whatever it wants, right? it can be outside MIN_LIMIT
[17:06:42] <cradek> yes HOME_OFFSET is the distance from here to where the switch is. it can be whatever.
[17:07:03] <sarariman_seb_> oops i got it backwards, MIN_LIMIT must be < HOME
[17:07:09] <sarariman_seb_> MIN_LIMIT < HOME < MAX_LIMIT
[17:07:14] <IchGuckLive> its basicly the point where you want the mashine to be after homing
[17:07:18] <cradek> it can be outside soft limits, because the soft limits are not established yet when seeking the switch
[17:07:25] <sarariman_seb_> right
[17:07:25] <sarariman_seb_> cool
[17:07:35] <cradek> sarariman_seb_: yes MIN_LIMIT < HOME < MAX_LIMIT
[17:07:55] <Connor> I want the machine to be at 0,0,0, and want my soft limits to be 0 too.. guess I can't have my cake and eat it too?
[17:08:02] <cradek> nope
[17:08:13] <cradek> make a very small negative soft limit
[17:08:28] <cradek> it could even be less than an encoder count
[17:08:36] <IchGuckLive> cradek: agree -0,1
[17:08:37] <Connor> I did the same thing kinda, just swapped it around.
[17:08:38] <cradek> you want 0 to be a valid position, so it must be INSIDE the limits
[17:09:11] <Connor> told the machine to goto 0.00001 which is smaller than a step on the stepper.. so, it's happy.
[17:09:13] <IchGuckLive> Zero is good for the koordinate limits also
[17:09:42] <IchGuckLive> the Zero of the part is at G54
[17:09:44] <cradek> Connor: but if you do G0 G53 X0 you'll get an error
[17:10:02] <cradek> you usually want 0 to be a valid coordinate
[17:10:09] <IchGuckLive> the moves on G53 is nood a good G-code
[17:10:42] <Connor> I don't recall getting a error when I got to 0, but I normal just do a G0 X0, no G53
[17:10:46] <IchGuckLive> use G54 insted so you are in the main ccordinate
[17:10:57] <IchGuckLive> only for tool length use G53
[17:11:18] -!- acemi [acemi!~acemi@unaffiliated/acemi] has joined #emc
[17:11:59] <sarariman_seb_> IchGuckLive, i use g53 for things like "quill up" and "bring the table out here where i can work on it"
[17:12:08] <IchGuckLive> G53 only for moving on the mashine system as Tool change position and tool length comp switch or partchang position
[17:12:30] <IchGuckLive> sarariman_seb_: agre
[17:13:15] <IchGuckLive> work on the part shoudt always be G54 or higher
[17:13:31] <IchGuckLive> this i tell the students here in Germany
[17:14:16] -!- kljsdfhklj has quit [Ping timeout: 246 seconds]
[17:14:23] <sarariman_seb_> IchGuckLive, i agree with that, use a work coordinate system for working on the .. work
[17:14:34] <cradek> this is all true but irrelevant to my point that you should set up homing such that 0 is a valid coordinate
[17:14:38] <sarariman_seb_> heh
[17:14:47] <sarariman_seb_> i agree with that too
[17:14:50] * sarariman_seb_ is very agreeable today
[17:14:58] <cradek> I agree with seb
[17:15:15] <Connor> so, what is the diff betwen G0 X0 vs G0 G53 X0 ?
[17:15:30] <sarariman_seb_> ooh, ooh, i know
[17:15:33] <Connor> and why don't I get soft limit errors when going to 0 after home is done ?
[17:15:39] <cradek> which 0 it goes to, the unoffset one (G53) or the currently offset one
[17:15:54] <sarariman_seb_> "g0 x0" goes to whatever place your currently selected coordinate system thinks is 0
[17:16:07] <cradek> I agree :-)
[17:16:09] <sarariman_seb_> "g53 g0 x0" goes to 0 in the fixed machine coordinate system
[17:16:27] <Connor> well, for this, all 0's are the same. I've not touched off anything..
[17:16:53] <sarariman_seb_> if the coordinate systems happen to have the same origin and rotation, then yes there's no functional difference
[17:17:23] <Connor> So, with soft limit being 0, why don't I get errors when I tell the syste, tp gp tp 0
[17:17:24] <cradek> ... and tool offset
[17:17:39] <cradek> Connor: I must be wrong that it will cause an error
[17:17:40] <cradek> bbl
[17:19:58] <Connor> cradek: I'm not saying your wrong.. I just don't remember getting one.. I'll test it in just a few..
[17:20:59] <Connor> Like I said, I think the issue was the machine reads negative when it hits 0 coming from the negative side.. when it hits 0 from the positive side, it's fine...

[18:27:06] <danimal_garage> hi
[18:29:45] <danimal_garage> having some problems finding an example to hook up a spindle encoder to my 5i20
[18:30:18] -!- sarariman_seb_ [sarariman_seb_!~seb@] has joined #emc
[18:30:47] <danimal_garage> i found some stuff for spindle feedback in the integrator's manual but it was more for using parport pins
[18:31:51] <danimal_garage> the encoder is not showing any counts in hal scope
[18:33:23] <danimal_garage> i have ENCODERS = 3 in hal
[18:34:11] <sarariman_seb_> are you using software encoders in emc? or hostmot2, or something else?
[18:35:43] <danimal_garage> hostmot2
[18:36:07] <sarariman_seb_> and you have three axes of servos?
[18:36:17] <danimal_garage> i'm trying to pastebin my hal but i cant get online for some reason
[18:36:24] <danimal_garage> 2, it's a lathe
[18:36:29] <sarariman_seb_> ah, ok
[18:37:28] <sarariman_seb_> does "halcmd show pin hm2*encoder*" show the expected number of encoder inputs?
[18:38:07] <danimal_garage> good question

[18:38:48] <danimal_garage> if they're showing in halscope, it must be set for the correct amount, right?
[18:38:57] <sarariman_seb_> oh yeah you're right
[18:39:28] <danimal_garage> it's a ttl encoder, i set the jumper right i believe on the 7i37
[18:39:33] <sarariman_seb_> the first two work (show counts changing), but the last one (number 2) doesnt?
[18:39:41] <danimal_garage> or 7i33, i get them mixed up
[18:40:17] <danimal_garage> well the axii are o and 2 for some reason, but yea, they show counts and 1 doesnt
[18:40:18] <sarariman_seb_> scope the encoder wires where they go in to the 7i33
[18:40:43] <danimal_garage> i dont have a scope but i checked them with an analog volt meter and it appears to be working fine
[18:40:54] <sarariman_seb_> if there's good signals on the 7i33, they'll show up in hal
[18:41:03] <danimal_garage> or at least working to the point where it should register a count
[18:41:43] <danimal_garage> thats what i thought
[18:42:29] <sarariman_seb_> is your encoder push/pull? or does it let its output signals float for part of the wave? i have one like that, it's annoying and needs pull{up|down} resistors at the 7i33 to complete the waveform
[18:43:24] <danimal_garage> http://pastebin.com/Q055NfxT
[18:43:34] <danimal_garage> i'll check the data sheet
[18:47:02] <danimal_garage> it says pullup resistors are provided'
[18:47:21] <danimal_garage> but i dont know if that means they're already in the encoder
[18:47:56] <danimal_garage> i did see an encoder in there
[18:48:08] <danimal_garage> opps i mean i did see a resistor in there
[18:49:43] <danimal_garage> it says single ended ttl compatible outputs from a lm339 open collector output stage 2kohm resistors are provided

[19:17:40] <danimal_garage> hal meter just shows the spindle speed as the commanded speed
[19:18:07] <danimal_garage> and the spindle-at-speed signal is false
[19:26:51] <danimal_garage> this gearchange thing seems to complicate things
[19:32:42] -!- andypugh [andypugh!~andy2@cpc2-basl1-0-0-cust1037.basl.cable.virginmedia.com] has joined #emc
[19:40:25] <danimal_garage> so the near component is working
[19:41:05] <danimal_garage> i got it so spindle-at-speed is true by adjusting the scale
[19:42:55] <danimal_garage> if the spindle starts slowing down due to load and it's out of the near scale for spindle-at-speed, what happens when you're feeding with feed per rev?
[19:43:20] <danimal_garage> does it just stop, or does it try to ramp up the spindle to compensate?
[19:43:43] <danimal_garage> or does it just slow down the feedrate to match the fpr?
[19:52:33] <andypugh> It slows the feedrate
[19:52:48] <danimal_garage> i have a problem with the spindle stalling under load occasionally, and it breaks tools. My goal is to have it so it doesn't just keep feeding when the spindle stops, i want the feed to compensate for the spindle slowing
[19:53:07] <andypugh> FPR should do that
[19:53:16] <danimal_garage> is there any way to test it to make sure it's working?
[19:53:19] <andypugh> You can also try setting up closed-loop spindle control.
[19:53:32] <danimal_garage> thats what i would like
[19:53:43] <danimal_garage> i'm trying to figure out how to do it
[19:53:49] <andypugh> I assume you have a spindle encoder?
[19:53:53] <danimal_garage> yes
[19:54:19] <danimal_garage> it's hooked up and the motion.spindle-speed-in pin seems to register the counts correctly
[19:54:39] <andypugh> halcmd setp (spindle scale) (spindle scale x 2) with the machine air cutting should halve the feed rate
[19:54:52] <danimal_garage> ah ok
[19:55:06] <danimal_garage> thanks
[19:55:08] <andypugh> Or just do it with the spindle override slider.
[19:55:20] <andypugh> (the first way is more "convincing")
[19:55:26] <danimal_garage> ok
[19:55:59] <danimal_garage> do i need a closed loop spindle control for threading?

[20:09:06] <danimal_garage> ha
[20:16:29] <danimal_garage> looks like it works
[20:16:44] <danimal_garage> the feedrate fluxuates a little under load
[20:16:54] <danimal_garage> so it's keeping in time with the spindle

[20:27:16] <danimal_garage> i believe it does
[20:27:21] <danimal_garage> but i'll check
[20:27:32] <danimal_garage> thanks
[20:27:36] <andypugh> I am rather disappointed. My drive can't move my Z axis.
[20:28:48] <skunkworks> yeck - too much friction/weight?
[20:29:07] <andypugh> As it can only just move it down, I go for friction.
[20:29:58] <sarariman_seb_> you have a screw that's not loose enough ;-)
[20:30:16] <andypugh> I can't fit in any higher gear ratio, so it looks like I need to try a ballscrew rather than the Acme.
[20:30:24] <tom3p> no, its upside down ;)
[20:30:34] <andypugh> The Acme was always a bit of a gamble.
[20:31:16] <andypugh> I suppose, in principle, I could cut some of the machine away and go for a much higher gear ratio.
[20:31:36] <tom3p> pic of machine?
[20:31:45] <andypugh> If it went down but not up I would be looking at a counterbalance.

[22:37:20] <atom1> broken?
[22:38:18] <Paragon39> The spindle itself I measured about .01mm runout but I progress onto the R8 collet holder it gets worse to the point the I can see the collet hole rotating out of line measured a runnout on the edge of a 3mm drill rod and getting nearly .16mm runout! :-(

[23:41:09] <andypugh> Do you have any proper mountain passes like this? http://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=stelvio&aq=&sll=54.40432,-3.154063&sspn=0.017985,0.036263&ie=UTF8&hq=stelvio&hnear=Parco+Nazionale+dello+Stelvio,+Via+Alberto+De+Simoni,+42,+23032+Bormio+Sondrio,+Lombardia,+Italy&ll=46.532296,10.468082&spn=0.042514,0.072527&t=h&z=14
[23:44:10] <JT-Shop> yes like atom1 said the blue ridge mountains or pikes peak
[23:44:54] <andypugh> My only knowledge of the Blue Ridge Mountains comes from Laurel and Hardy singing....
[23:45:03] <JT-Shop> LOL
[23:45:23] <atom1> a few passes in colorado have some decent switchbacks
[23:45:59] <Valen> http://en.wikipedia.org/wiki/File:Gunbarrel-Highway-26-Jun-2007.jpg is a road
[23:46:06] <atom1> i think this beats all though: http://tom-itx.dyndns.org:81/~webpage/deathroad/deathroad_index.php
[23:46:09] <Valen> (thats actually a section of highway)
[23:46:31] <atom1> leave it to an aussie
[23:46:52] <Valen> its ok they made a new one to replace that http://en.wikipedia.org/wiki/File:Great_Central_Road_near_Tjukayirla.jpg
[23:48:04] <Valen> freshly graded too for the yuppies
[23:48:41] <andypugh> There is somewhere in Norway where the road enters a tunnel, then spirals up though solid rock to the top of the Fjord.
[23:48:41] <Valen> heh if you look at the full size of that first image you can see the road disapering over the hill
[23:48:55] <Valen> andypugh: thats cool
[23:51:14] <Valen> http://maps.google.com.au/maps?f=q&source=s_q&hl=en&geocode=&q=woomera+la9&sll=-33.753334,150.722553&sspn=0.014612,0.033023&ie=UTF8&hq=la9&hnear=Woomera+South+Australia&ll=-30.936391,136.62323&spn=0.964719,2.113495&t=h&z=10 is about the closet I've been
[23:51:35] <Valen> actually I think the jupiter 2 launch pads were further out
[23:52:28] <andypugh> Lake Gairdner is where Rosco McLashan drives very fast isn't it?
[23:53:46] <andypugh> http://www.aussieinvader.com/land_speed_record_car_build.php
[23:54:21] <andypugh> Though my money is on http://www.bloodhoundssc.co.uk/
[23:54:59] <andypugh> You can actually download the full CAD files of Bloodhound, which is rather cool.
