[00:14:17] <Connor> Hey guys, need some advise on how to wire in my charge pump on my setup.
[00:15:18] <Connor> I have a C10 BOB, the charge pump and 3 5056 drivers, along with a C41 PWM based speed controller.
[00:16:40] <Connor> When I booted up just a few min ago, the spindle came alive without EMC being on, which is really not cool.
[00:26:29] <Jymmm> what is a "C10 BOB" ?
[00:26:38] <Connor> C10 Break out Board
[00:26:47] <Jymmm> what is "C10"
[00:26:57] <Connor> CNC4PC model number for the BOB
[00:27:11] <Jymmm> and we know that why?
[00:27:28] <Jymmm> and "5056"?
[00:27:40] <Jymmm> and "C41" ?
[00:28:02] <Connor> I thought it was pretty common part among CNC. 5056 is the Keling Stepper Drivers, and the C41 is the speed controller.
[00:28:11] <Connor> http://www.cnc4pc.com/Store/osc/product_info.php?cPath=33&products_id=45 <- C10
[00:28:25] <Connor> http://www.cnc4pc.com/Store/osc/product_info.php?cPath=25&products_id=303 <- C41
[00:28:41] <Connor> http://www.cnc4pc.com/Store/osc/product_info.php?cPath=23&products_id=51 <- C4 Charge Pump
[00:29:21] <Jymmm> I think we looked at cnc4c stuff once a long time ago, and just kept looking.
[00:29:35] <Connor> who is "we"
[00:29:44] <Jymmm> a couple of us on here
[00:30:51] <Connor> *shrug*
[00:31:21] <Connor> I have it all working.. except I'm not sure how to wire the Charge pump in..
[00:31:34] <Connor> well... the better way of saying that, is WERE to wire it in at.
[00:31:43] <Jymmm> if you had that chargepump connected and sindle turned on during power up of the pc. either 1) you wired it wrong, or 2) it's defective.
[00:32:06] <Connor> No. I didn't at the time, that's why I want to wire it in. :)
[00:32:40] <Jymmm> do you even have a mechancal estop setup yet?
[00:32:54] <Connor> not for the steppers, their is one on the spindle.
[00:33:13] <Jymmm> and the difference being?
[00:33:38] <Connor> that it's strictly wired into the spindle.
[00:33:48] <Jymmm> it's not a selective estop, it's an estop... EMERGENCY STOP, as in STOP EVERYTHING, NOW!
[00:33:50] <Connor> it's factory installed in the mill
[00:33:55] <Jymmm> so?
[00:34:28] <Jymmm> if the table is about to crush your fingers, do you want the BRB (big red button) to save you?
[00:35:15] <Jymmm> it's ESTOP, not an "oh shit I made a mistake stop"
[00:35:26] <Jymmm> bbiab
[00:35:35] <Connor> Dude, I know. I'm not their yet. I'm still in the middle of the conversion.
[00:36:58] <Connor> I was saying that the mill was manual, had a E-Stop for the spindle. It's not wired into anything but the spindle.. and most likely will have the Big Red Button taken off and be used as push to start push to stop for the spindle. and a bigger E-Stop button placed else were.. most likely in series with the charge pump, AFTER I figure out were to hook the charge pump up.
[00:37:56] <toastydeath> I've only worked on one manual machine that had a legit estop for the table
[00:38:07] <toastydeath> and that didn't brake the spindle it only turned it off
[00:40:38] <Connor> I don't think it applies breaks to the spindle.. but it slows down pretty quick. but, that's all another subject.. I was just trying to get advise on were to wire the charge pump at.
[00:41:23] <Connor> disable the BOB, which kills all the signals to the machine.. etc etc..
[01:10:56] <Jymmm> SWPadnos: hey
[01:13:14] <Jymmm> Connor: a chargepump is added to the physical ESTOP chain
[01:16:15] <Jymmm> Connor: Think if having a fire alarm on your home. Then you build an addition to your home, and extend the alarm system to cover the new area, the extended part is the chargepump
[01:16:31] <Jymmm> and the original alarm system being the estop chain
[01:17:29] <Jymmm> Connor: you also have to decided what you want it to do when the computer crashes of loses power.
[01:17:52] <Jymmm> if the pc comes back up, do you want it to turn back on?
[01:18:27] <Jymmm> this is where a safety relay comes into play as a main part of the physical estop chain.
[02:11:49] <DJ9DJ> moin
[02:12:01] <DJ9DJ> Hola Jymmm
[04:43:18] <Loetmichel> mornin
[05:24:49] <awallin> hm new i7 processors on the way... must resist upgrade... must...
[06:55:49] <ReadError> hey
[06:56:04] <ReadError> whats some good endmills (generic) for aluminum and plastics
[06:56:09] <ReadError> for just general cutting
[06:56:48] <jthornton> any with a razor sharp edge will work
[06:57:41] <jthornton> I don't know what you mean by generic
[07:20:33] <r00t4rd3d> cheap
[07:23:01] <awallin> ReadError: http://www.ctctools.biz ?
[07:23:48] <jthornton> cheap and good don't go in the same sentence
[07:24:41] <ReadError> like
[07:24:46] <ReadError> something decent
[07:24:51] <ReadError> from amazon
[07:24:59] <ReadError> i ordered a magenetic base + dial indicator
[07:28:06] <Jymmm> There is only ONE for plastic, which also does aluminum too... http://www.plasticrouting.com/
[07:29:38] <Jymmm> Is mineral spirits the same as mineral oil ?
[07:29:54] <jdhnc> not even close.
[07:35:51] <Valen> good cutters for plastic are quite different to metals
[07:36:00] <Valen> I wouldn't use a plastic cutter on Al
[07:36:07] <Valen> it wont be a plastic cutter after
[07:39:48] <Valen> you can use an Al cutter on plastic, but the finish probably won't be as good
[07:41:34] <Jymmm> Valen: The geometry of onsrud cutters it completely different than typically tooling
[07:41:50] <Valen> onsrud?
[07:42:07] <Jymmm> Valen: the thing youve been commenting about
[07:42:44] <Valen> fairynuff
[07:53:27] <Jymmm> Valen: http://www.plasticrouting.com/Van.asp
[08:19:34] <ReadError> http://i.imgur.com/OFAo8.png
[08:19:46] <ReadError> i set z to -5.5 - 0
[08:19:52] <ReadError> home -4
[08:20:00] <ReadError> but it shows it below the work piece ?
[08:21:10] <DJ9DJ> for my linuxcnc, positive z-values are up...
[08:21:25] <jthornton> yep Z-4 is below the work
[08:21:26] <DJ9DJ> and negative values are below the surface of the work piece...
[08:21:36] <DJ9DJ> so i think its okay
[08:25:25] <joe9> what should the size of the hole be to allow a #10-32 screw to pass through (with close clearance)? I found this article, but, it appears suspicious, hence wanted to check: http://en.wikipedia.org/wiki/Drill_and_tap_size_chart
[08:26:02] <jdhnc> what looks suspicious?
[08:26:55] <DJ9DJ> for non-imperial people... what does #10-32 mean? what do these numbers stand for?
[08:27:09] <jdhnc> #10 size, 32 threads per inch
[08:27:27] <DJ9DJ> 10 what?
[08:27:42] <jdhnc> 10 being less than 12 and bigger than 8
[08:27:46] <archivist> just a number
[08:27:49] <DJ9DJ> lol
[08:27:50] <DJ9DJ> okay ;)
[08:27:58] <DJ9DJ> thats crazy
[08:28:03] <Tom_itx> what does m2 mean???
[08:28:07] <jdhnc> there are crazier
[08:28:09] <Valen> Metric 2MM
[08:28:16] <Tom_itx> :)
[08:28:16] <jdhnc> how about '12 gauge'
[08:28:24] <Tom_itx> that's a shotgun
[08:28:29] <DJ9DJ> m2 is straight forward compared to #10 ;)
[08:28:31] <jdhnc> sure, but it has units
[08:28:32] <Valen> #10 is probably related to how many grains of rice will fit in it or something
[08:28:33] <archivist> which gauge are you referring too
[08:28:48] <jdhnc> shotgun in this case.
[08:29:03] <jdhnc> it at least makes (bad) sense.
[08:29:21] <DJ9DJ> hm
[08:29:46] <Tom_itx> jdhnc well there are gages for wire and sheet
[08:30:11] <jdhnc> sure
[08:31:08] <Tom_itx> 12 gage steel is .105", stainless is .109 and 12 gage wire is .0807"
[08:31:22] <jdhnc> of course.
[08:31:41] <DJ9DJ> lol
[08:31:57] <jdhnc> and a 12 gauge shotgun bore is about 0.729"
[08:32:12] <jdhnc> or, a sphere of 1/12 lb of lead
[08:33:35] <Jymmm> 12ga aluminum is .0808
[08:34:14] <Tom_itx> machine screws are numbered below 1/4" starting with 0-80 which takes a 3/64
[08:34:16] <Tom_itx> drill
[08:34:21] <ReadError> joe9: on your config, the 1st value for Z is -6 ?
[08:34:25] <ReadError> -6 and 0
[08:34:29] <Tom_itx> going up to a #14 screw
[08:34:38] <Tom_itx> then it switches to fractions
[08:34:47] <Tom_itx> confused?
[08:35:41] <jdhnc> I don't think I've ever seen a #14
[08:35:57] <Tom_itx> it's probably not that common
[08:36:04] <Tom_itx> neither is an 0-80
[08:36:44] <jdhnc> neve seen a 1 or 0 either
[08:36:52] <joe9> jdhnc: so, it is just a #10 gauge. If I have 10 gauge hole (in imperial), I should be good.
[08:36:54] <skunkworks> http://www.youtube.com/watch?v=zORLFMsDy5A
[08:37:23] <joe9> ReadError: yes, the travel of Z-axis is 6 inches. and it goes from 0 (top) to -6 (bottom).
[08:37:35] <jdhnc> joe9: tight is usually tight. Why so tight?
[08:37:40] <joe9> and my home is -0.5 inches on Z, iirc.
[08:38:04] <joe9> jdhnc: no need to be tight, what would be a good size for a hole to have?
[08:38:13] <Valen> my home positions are all over the shop
[08:38:15] <joe9> to fit a #10-32 gauge screw to go through.
[08:38:43] <Valen> z is about the middle x is at ~1/3rd and y is riiiight at the back
[08:38:43] <joe9> jdhnc: just enough that it is not a lot of movement in there.
[08:38:50] <Jymmm> joe9: #7 drill bit or 0.201"
[08:38:50] <ReadError> oh so your 1st box is 0 ?
[08:38:55] <ReadError> when you do the stepper config ?
[08:39:11] <awallin> for metric the drill used is smaller by about the pitch of the thread. i.e. M6 has 0.5mm pitch so drill with 5.5mm. fwiw...
[08:39:34] <jdhnc> awallin: makes too much sense, it will never catch on.
[08:40:06] <joe9> ReadError: these are my step configuration values: http://codepad.org/C0wAhJfa
[08:40:13] <DJ9DJ> for M6, the drill size for thread is 5mm
[08:40:27] <joe9> ReadError: and, this is my .ini file: http://codepad.org/Bs7qgMQ8
[08:40:37] <Tom_itx> DJ9DJ what's the clearance size?
[08:40:40] <joe9> ReadError: and, my .hal file: http://codepad.org/WBIm9dJs
[08:40:43] <awallin> DJ9DJ: oh, ok, maybe the pitch is 1mm..
[08:40:44] <jdhnc> I need some flat-head M4's to mount my power supplies
[08:40:59] <Jymmm> Ewwwwwwwwwww
[08:40:59] <joe9> Jymmm: thanks a lot.
[08:41:00] <awallin> M3 might be 0.5mm pitch and drill is 2.5mm ?
[08:41:01] <DJ9DJ> awallin: http://lookass.ch/content_engineering/Kernlochdurchmesser_Gewinde.pdf
[08:41:13] <DJ9DJ> awallin, yes
[08:41:28] <joe9> i prefer metric over imperial, given that I was trained in metric.
[08:41:36] <joe9> but, whatever works.
[08:41:46] <DJ9DJ> Tom_itx, clearance size? dunno, I am not a mechanic engineer or something ;)
[08:41:46] <jdhnc> is there any reason not to power my 7i43 from a 5V disk power cable?
[08:41:50] <Jymmm> joe9: http://www.sizes.com/tools/twist_drills.htm
[08:41:51] <jdhnc> joe9: where are you from?
[08:42:02] <awallin> DJ9DJ: it's nice they have the spindle RPM with five significant figures in that table. just in case you have a spindle that keeps RPM with 0.01% precision..
[08:42:10] <joe9> jdhnc: was not trained in the US.
[08:42:27] <jdhnc> where were you trained? or is it a secret?
[08:42:46] <jdhnc> (you don't need to answer if it is!)
[08:42:52] <joe9> jdhnc: i was not trained in machining at all. but, I am not a native american. an immigrant.
[08:43:03] <joe9> my schooling was not in the States.
[08:43:17] <DJ9DJ> hihi
[08:43:59] <jdhnc> that leaves a lot of places.
[08:44:09] <Jymmm> Yeah, Canada
[08:44:23] <Jymmm> Those damn illegal Canucks!
[08:44:53] <Jymmm> oh yeah, I forgot to say... Eh
[08:45:36] <joe9> Jymmm: thanks, that url is very helpful.
[08:45:42] <joe9> Jymmm: india
[08:45:50] <joe9> sorry, jdhnc. ^^
[08:46:21] <joe9> there is a lot of anti-indian feeling in the software irc channels. so, just was not sure how it would be received here.
[08:46:29] <Jymmm> joe9: India?! There's only two things come from india... call centers and curry =)
[08:46:33] <jdhnc> really?
[08:46:40] <Jymmm> joe9: http://www.sizes.com/tools/thread_NCNF.htm
[08:47:21] <Jymmm> joe9: That's probably the $5 software developemnt that you are getting vibes from
[08:47:29] <joe9> yes.
[08:48:32] <JT-Shop> I thought India didn't eat curry only the English have curry???
[08:49:29] <Jymmm> JT-Shop: Did you know that Curry doens't have curry in it
[08:49:43] <JT-Shop> lol
[08:49:48] <Jymmm> seriously
[08:50:26] <archivist> the joke on one of the comedies here was lets have an english
[08:50:42] <Jymmm> Curry (the spice blend/sauce) doens't contain curry (the plant)
[08:53:23] * archivist blames JT-Shop ...../me starts a shed http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_04_23_shed/
[08:55:48] <jdhnc> is that a shed by the shed?
[08:56:43] <JT-Shop> archivist: what are the framing material made from?
[08:56:45] <Jymmm> jdhnc: Can't you see archivist waving his hand in the window of his livingroom?
[08:56:48] <archivist> er yes, those are just past the other shed
[08:57:17] <Jymmm> jdhnc: you should see the kitchen! =)
[08:57:28] <jdhnc> I need a shed to get rid of the lawn crap I never use.
[08:57:34] <archivist> JT-Shop, upvc window frames
[08:57:46] <Jymmm> jdhnc: it's called the curb
[08:57:59] <jdhnc> Jymmm: well, I do use it infrequently.
[08:58:04] <jdhnc> some of it anyway
[08:58:19] <jdhnc> I use the edger every other year and reclaim 2ft of my driveway
[08:58:29] <Jymmm> archivist: 'U' pvc ?
[08:58:30] <archivist> JT-Shop, helps that I know a local window company and those are miss measures
[08:58:39] <JT-Shop> cool
[08:58:57] <jdhnc> know a paint & shingle shop?
[08:59:18] <Jymmm> archivist: 'u' being UV additives?
[08:59:41] <archivist> no, but got melamine coated plywood for the roof,floow and wall
[08:59:52] <archivist> Jymmm, YES
[09:00:15] <Jymmm> archivist: is that common in UK or more of a speciality thing?
[09:00:24] <archivist> common
[09:00:32] <Jymmm> Hmmm
[09:00:53] <Jymmm> Maybe it's just implied here in the states.
[09:01:02] <archivist> that and double glazed glass units
[09:01:43] <Jymmm> Yeah, only the last 10years or so have double and even tripple glazed have become common
[09:02:55] <Jymmm> archivist: The nice thing about that vinyl is the condensation factor, or lack there of.
[09:04:34] <Jymmm> archivist: Do you know if you have to compensate for thermal expansion?
[09:06:05] <archivist> not been made aware of any thermal issues and I should have caught on as I sat at the window company doing the website
[09:07:09] <archivist> window stuff has loads of clearance and gaps filled with flexible silicon
[09:07:44] <Jymmm> archivist: Ok, cool. I've just never seen any THAT large used as walls alone without being framed into something else.
[09:08:32] <archivist> those were for a conservatory and are load bearing
[09:08:42] <Jymmm> Oh, nice!
[09:08:44] <archivist> just a metre too long :)
[09:08:53] <Jymmm> Ooooops ;)
[09:09:19] <archivist> better for me 12ft sides :)
[09:10:21] <Jymmm> do any of the holes allow for a sliding window?
[09:10:22] <ReadError> odd im using the same settings as joe
[09:10:31] <ReadError> and emc thinks the spindle is below the work peice
[09:12:12] <archivist> Jymmm, no
[09:12:29] <jdhnc> did you touch off to some place below?
[09:12:36] <Jymmm> archivist: Bummer, that would have been a nice addition
[09:12:51] <Jymmm> Interesting... http://www.sizes.com/sports/shotguns.htm
[09:20:15] <alex_joni> heh http://failblog.files.wordpress.com/2012/04/white-trash-repairs-there-i-fixed-it-you-sure-that-gravel-is-secure-dave.png
[09:30:42] <Jymmm> alex_joni: Seen it before. I was thinking it had to be to hold up the side doors, but when the gravel shifts, the straps would loosen so that doens't make sense either.
[09:36:23] * cpresser bets that there is somthing else hidden under the gravel
[09:38:01] <archivist> probably to stop the remote controlled sides dropping while in transit
[09:38:19] <Vq> Or perhaps it's solid part of a statue and not gravel. :o)
[09:38:28] <Vq> A weird statue...
[09:38:58] <cpresser> 'its art' always is an valid answer^^
[09:40:25] <Vq> Yep, nothing is hard to explain anymore. :)
[11:39:54] <JT-Shop> who is e-ndy and why does his nick change so much?
[11:40:35] <ReadError> runnin from the law
[11:44:00] <djdelorie> JT-Shop: "afk" == "away from keyboard"
[11:50:08] <jdhnc> I doubt anyone cares.
[11:50:14] <JT-Shop> yea
[11:50:42] <djdelorie> maybe it does it automatically when his screensaver kicks in...
[11:52:07] <JT-Shop> ah I understand now
[11:56:01] <JT-Shop> dang these crab chips are good
[12:02:49] <jdhnc> c'mon admit you see nothing factual about 'forgiving student loans'
[12:02:57] <jdhnc> <urk>
[12:03:15] <Loetmichel> re @ home
[12:31:50] <IchGuckLive> hi all out there in the World
[12:35:25] <Loetmichel> soo, female snap-in-IEC21-C14 are here, now the back panel of the CNC is complete... -> http://www.cyrom.org/palbum/main.php?g2_itemId=13143
[12:35:56] <Loetmichel> ... just a "bit" of wireing inside and then i can move to the x and z axis hardware ;-)
[13:03:48] <mhaberler> suggested viewing: http://www.youtube.com/watch?v=yJPLJGdiQWw&feature=plcp&context=C494ebbdVDvjVQa1PpcFOUhIqfm3XcEJtse1eR8fqk7sO0WffoNSU%3D
[13:06:39] <archivist> well done!
[13:06:41] <cpresser> mhaberler: some gantry users will like this. right now i am using a hal-module which intercepts pos-command in hal. only for z to retract the tool.
[13:07:03] <cpresser> it looks like i can drop my ugly code soon and adapt yours :)
[13:07:04] <mhaberler> oh man
[13:07:21] <mhaberler> this just started working, aint ready for prime time
[13:07:27] <archivist> hehe
[13:07:31] <mhaberler> but it will
[13:08:34] <IchGuckLive> mhaberler: why not retract in Axis order Z first
[13:09:05] <mhaberler> I leave that as an exercise for you ;)
[13:09:09] * cpresser quotes: "aint ready for prime time"
[13:09:16] <IchGuckLive> if im down and it retracts crossover and moves back crossover thats in most cases not a planed
[13:09:48] <IchGuckLive> mhaberler: im stil fighting with my G12/G13
[13:09:51] <mhaberler> that isnt the point - the conventional wisdom was this is next to impossible to do with
[13:10:37] <IchGuckLive> but i will wait for the next LTS main streaam support
[13:10:45] <mhaberler> ?
[13:10:53] <IchGuckLive> 2.60
[13:11:10] <mhaberler> whatever lights your candle ;)
[13:11:18] <IchGuckLive> B)
[13:18:48] <skunkworks> mhaberler: nice work!
[13:18:57] <jdhnc> I can't see the video here. How do you trigger it?
[13:19:27] <mhaberler> the devil is in them details..
[13:19:52] <mhaberler> re video: open the link in your browser, like any youtube video?
[13:20:16] <skunkworks> jdhnc: it is a button on his side panel
[13:20:16] <jdhnc> can't from here.
[13:20:43] <jdhnc> cool
[13:20:54] <jdhnc> instant, or at end of current line or what?
[13:22:41] <skunkworks> mhaberler: how much more to be able to touch-off the tool - change offsets and such then restoart. (that is going to be the next question from people...)
[13:22:48] <skunkworks> restart?
[13:23:06] <mhaberler> uh...
[13:23:14] <mhaberler> let me sleep over it
[13:23:17] <skunkworks> heh
[13:23:37] <skunkworks> Really - I don't miss it (didn't know I was missing it) but people seem to really want it.
[13:27:13] <jdhnc> I'd like to be able to move and clean out, but I guess I could program in two tool changes and jog it out of the way to clean
[14:21:17] <alex4nder> hey
[14:52:11] <ThadiusB> finally, everythings in order :)
[14:58:18] <alex4nder> joe9: hey
[14:58:29] <joe9> alex4nder: hello.
[14:59:05] <ThadiusB> hello
[14:59:17] <joe9> ReadError: can you please check if the mills were delivered a day early, by any chance?
[15:02:14] <ThadiusB> think he said he was in a conference
[15:41:07] <joe9> ThadiusB: ok, thanks.
[15:41:31] <Tom_itx> JT-Shop some ppl have all the luck.
[15:43:44] <Tom_itx> i stopped by the scrap yard to see if i could find some U extrusion or something to use for a heatsink for the 203v's and would up stumbling on this so i had them slice me of 3' of it: http://tom-itx.dyndns.org:81/~webpage/temp/cnc/psu/heatsink1.jpg
[15:44:12] <Tom_itx> even tagged 'heatsink' on the back
[15:44:20] <Thetawaves> NICE
[15:44:28] <Thetawaves> i have real problems locating heat sinks
[15:44:37] <Tom_itx> i didn't really need all 8'
[15:44:47] <Tom_itx> maybe i should have grabbed it
[15:47:00] <Tom_itx> i was gonna use a slab of 5/8 alum if i couldn't find anything else
[16:15:05] <DJ9DJ> gn8
[16:19:52] <JT-Shop> Tom_itx: how is that?
[16:24:18] <alex4nder> ok.. this board wins the latency tests
[16:26:40] <alex4nder> Max jitter on 1ms thread ... 27 nS
[16:26:48] <djdelorie> wow
[16:27:10] <alex4nder> Max jitter on 25 uS thread ... 15 nS
[16:27:22] * alex4nder does the super RTOS dance.
[16:30:07] <ReadError> hey alex4nder
[16:30:09] <JT-Shop> archivist: do you use any low cost reliable stepper driver boards that are available in the UK?
[16:30:12] <ReadError> what values are you using on Z?
[16:30:18] <ReadError> i set it to -6 -> 0
[16:30:24] <ReadError> but it shows it as below the work piece
[16:30:38] <alex4nder> did you touch off the workpiece?
[16:31:37] <andypugh> alex4nder: That sounds unfeasible.
[16:32:05] <andypugh> JT-Shop: www.zappautomation.co.uk
[16:32:13] <alex4nder> andypugh: it is unfeasible using RTAI on Linux
[16:32:25] <andypugh> Ah, I see.
[16:32:31] <andypugh> What are you using?
[16:33:08] <alex4nder> I've started porting the motion/kins/stepgen/hal to ChibiOS
[16:33:24] <andypugh> Sounds like quite a project.
[16:33:38] <alex4nder> I'm just messing with it right now.
[16:34:03] <andypugh> What's the application? As far as I can see Linux/RTAI is good enough for most CNC purposes?
[16:34:11] <alex4nder> my mill
[16:34:32] <alex4nder> it doesn't 'need' it.
[16:34:40] <alex4nder> but I don't really 'need' a mill either. ;)
[16:36:01] <andypugh> Now that's just crazytalk!
[16:38:48] <Tom_itx> JT-Shop did you see the piece of heatsink i found at the scrap today?
[16:42:16] <ReadError> alex4nder: http://i.imgur.com/OFAo8.png
[16:42:22] <ReadError> thats what it thinks is happening
[16:42:38] <JT-Shop> andypugh: thanks
[16:42:44] <JT-Shop> Tom_itx: yes, good score
[16:43:24] <djdelorie> ReadError: at the same time, take a picture of the mill
[16:43:51] <alex4nder> right
[16:44:20] <alex4nder> you didn't touch off on Z?
[16:48:36] <andypugh> Interesting, the Glade editor calls some widgets "Dialogue" Is that a bit of localisation?
[17:34:36] <tom3p> mhaberler, very nice on the interrupt/retract/return/continue. wrote longer email about it, hope it makes it to you. i dont see it on list yet.
[17:34:38] <tom3p> thanks!
[17:35:45] <tom3p> oh, thanks andy!
[17:37:05] <tom3p> argh "fatal: Not a git repository (or any of the parent directories): .git" will try next time i get inet, thx 4 now
[18:17:19] <Tom_itx> JT-Shop do you happen to have the hole layout for the 203v?
[18:17:24] <Tom_itx> or anyone for that matter
[18:17:47] <JT-Shop> Tom_itx: I think it is in the manual
[18:17:53] <Tom_itx> i didn't see it
[18:17:59] <Tom_itx> or don't have the right manual
[18:18:02] <JT-Shop> if not I can measure my spare one
[18:18:57] <Tom_itx> i was looking at a heatsink on pmdx.com but i don't see all the dimensions given
[18:19:07] <Tom_itx> http://www.pmdx.com/Doc/PMDX-Heatsink-01_Rev_11.pdf
[18:19:31] <Tom_itx> x is given but not y
[18:19:38] <Tom_itx> at least not that i see
[18:20:15] <JT-Shop> Mounting Pattern: 4 6-32 screws, 1.75 by 2.375 (44.5 mm, 60 mm)
[18:20:28] <Tom_itx> it may be the 1.712 and 4.112
[18:20:34] <Tom_itx> i can't tell for sure
[18:20:56] <JT-Shop> says 1.75x2.375 in the manual
[18:21:25] <Tom_itx> ok i see that. i was looking for a layout :)
[18:21:41] <Tom_itx> how far between drivers?
[18:21:49] <JT-Shop> I thought I saw it in there
[18:21:52] <JT-Shop> let me see
[18:22:04] <Tom_itx> i'll compare it to the website's drawing
[18:22:23] <Tom_itx> do you butt yours together or leave a gap?
[18:22:41] <JT-Shop> mine have quite a gap
[18:22:57] <JT-Shop> I'd leave some space for sure if possible
[18:23:10] <JT-Shop> 2.5 x 2.5 case size
[18:23:10] <Tom_itx> 1/4"?
[18:23:21] <JT-Shop> ?
[18:23:26] <Tom_itx> between drives
[18:23:31] <JT-Shop> yea
[18:24:52] <Tom_itx> that drawing shows them butted against each other
[18:25:51] <JT-Shop> that drawing sucks
[18:26:05] <Tom_itx> sure does but i've dealt with worse
[18:27:53] <JT-Shop> and it seems to be incorrect on the Y measurement if I cyphered it correctly
[18:28:31] <Tom_itx> well i got 1.712 and 4.112 for y
[18:28:38] <Tom_itx> for the drive holes
[18:29:21] <JT-Shop> that is 2.4 and gecko says 2.375
[18:29:37] <Tom_itx> that allows a little slop in the slot
[18:29:55] <Tom_itx> .010 approx
[18:29:57] <Tom_itx> per side
[18:30:08] <Tom_itx> that's not unreasonable
[18:35:22] <JT-Shop> yea, I guess that is what they wanted
[18:35:49] <Tom_itx> if the 2.375 fits may as well use it
[18:36:09] <JT-Shop> want me to measure my spare?
[18:36:22] <Tom_itx> mine'll be here thur
[18:36:37] <Tom_itx> i won't get to it til then anyway. just drawing a cad file for it
[18:37:31] <Tom_itx> they should know what their own hole pattern is
[18:38:33] <JT-Shop> yea
[18:53:07] <Tom_itx> JT-Shop, do you have a pic of where you mounted yours?
[19:16:10] <ReadError> hey hai hay
[19:35:20] <alex4nder> ReadError: sup
[19:41:47] <Jymmm> Anybody want a free shipping container?
[19:42:12] <Tom_itx> bury it in your yard for dooms day
[19:44:13] <Jymmm> why?
[19:44:15] <ReadError> alex4nder: u gonan be here for a sec?
[19:44:25] <ReadError> going to try to get this z axis goin
[19:44:30] <ReadError> only thing that needs fixin
[19:49:24] <JT-Shop> Tom_itx: http://s47.photobucket.com/albums/f163/johnplctech/Plasma%20Cutter/
[19:53:21] <Tom_itx> did you put pc fans behind yours?
[19:53:23] <Tom_itx> 80mm
[20:14:54] <Jymmm> SWPadnos: ping
[20:19:02] <alex4nder> ReadError: yah
[20:33:55] <ReadError> alex4nder, having a bad time trying to get this z axis set
[20:34:05] <ReadError> it goes in the write direction, but code gives errors
[20:34:07] <ReadError> saying out of range
[20:34:14] <ReadError> i did -6 and 0
[20:34:25] <ReadError> home at -4 (2" above bottom)
[20:34:48] <ReadError> then, i set the touchoff value to 2
[20:34:55] <ReadError> since its 2" above the piece
[20:35:04] <ReadError> and it goes up really high
[20:35:22] <ReadError> or should it be -4 for touchoff?
[20:35:29] <ReadError> since its from the Z, which exist above the machine?
[20:36:21] <Tom_itx> sounds like it, 2 would be greater than 0
[20:36:43] <ReadError> but, all these values are positive
[20:37:15] <ReadError> the emc says linear move on line 589 exceeds limit
[20:37:30] <ReadError> its these dang negative numbers i think
[20:38:06] <Tom_itx> are you using fixture offsets?
[20:38:11] <Tom_itx> g54 etc
[20:38:15] <ReadError> oh no
[20:38:18] <ReadError> i left that default
[20:38:24] <ReadError> which should i be using?
[20:38:28] <jdhnc> what is on line 589
[20:38:36] <Tom_itx> g54 is the default
[20:38:51] <ReadError> its the default emc demo jdhnc
[20:38:58] <ReadError> ide paste but no internet on it yet
[20:39:05] <jdhnc> move z to about halfway then touch off
[20:39:31] <jdhnc> if it is trying to move to a save Z height (positive) and you don't touch off, anything positive will be out of range.
[20:39:44] <jdhnc> the 2.4 emc demo or the 2.5 linuxcnc demo?
[20:39:58] <ReadError> 2.4
[20:41:26] <ReadError> when i home the z
[20:41:29] <ReadError> even though its -4
[20:41:34] <ReadError> it sets it to 0.5
[20:41:40] <ReadError> not sure how its getting that number
[20:41:54] <ReadError> since im bound between -6 and 0
[20:42:36] <ReadError> i dont have any tools set
[20:42:44] <jdhnc> when you touch off, it sets zero to wherever you are (unless you enter a non-zero value)
[20:42:45] <ReadError> so im not sure where it would be getting these extra numbers from
[20:42:54] <ReadError> i did home though
[20:43:00] <ReadError> and thats what set the +0.5
[20:43:11] <ReadError> home should be -4
[20:43:11] <jdhnc> line 589 on my demo is just a scaled y/z
[20:43:15] <jdhnc> do you have a home offset?
[20:43:35] <ReadError> yea -4
[20:43:45] <ReadError> which is 2" above my table
[20:43:56] <ReadError> assuming -6 is the table..
[20:45:14] <ReadError> now im getting, linear move on line 22 would exceed joint 2s limit
[20:45:20] <ReadError> since its seeing it as a positive number
[20:45:37] <jdhnc> did you move x halfway and then touch off?
[20:45:42] <ReadError> and 0 is the "largest" number
[20:45:52] <ReadError> yea my "home" is in the middle of x, y
[20:45:58] <ReadError> then z is 2" above
[20:46:01] <jdhnc> that's not home
[20:46:15] <ReadError> thats what i put in the config ;/
[20:46:22] <jdhnc> or it is home, but that's not what I meant.
[20:46:35] <jdhnc> jog z halfway up, hit <end><enter>
[20:48:57] <ReadError> ok that put it at 0
[20:49:11] <jdhnc> now run it
[20:49:21] <ReadError> error on 22 and 589 ;/
[20:50:03] <alex4nder> hmm
[20:50:16] <jdhnc> 22 is joint 0 or 1?
[20:52:42] <alex4nder> ReadError: what I'm using on my Taig is I have Z as 0 to 5.5 .. and home at 5.5"
[20:53:09] <alex4nder> when I home my machine I bring Z up right before the gib screw hits the bearing block
[20:53:18] <alex4nder> and I home Z
[20:54:11] <alex4nder> you should be able to go all the way up to that point, and 5.5" down
[20:55:01] <jdhnc> I think my top Z is +(max travel)
[20:55:56] <Tom_itx> it should be
[20:56:13] <jdhnc> anybody know anything about ER collets?
[20:56:34] <jdhnc> like, are these ER or some random thing: http://www.cdcotools.com/index.php (on sale, top right)
[20:56:46] <ReadError> oh
[20:56:53] <ReadError> everyone was saying that z should be negative
[20:56:57] <ReadError> -6 0
[20:57:15] <ReadError> well thats what i got from joes config
[20:57:21] <ReadError> this positive axis seems to be better
[20:58:23] <Tom_itx> jdhnc, http://www.maritool.com/Collets-ER-Collets/c21_56/index.html
[20:59:03] <alex4nder> ReadError: it's all relative
[21:00:01] <Tom_itx> alex4nder is that G90 or G91?
[21:00:09] <alex4nder> haha
[21:03:47] <jdhnc> tim: nice, but severe price difference
[21:04:45] <Tom_itx> i posted it more for a visual aid
[21:05:40] <ReadError> awwwww yea
[21:05:44] <ReadError> we got it goin ;)
[21:05:49] <ReadError> screw that negative stuff
[21:06:06] <ReadError> how much fail will happen if i try to draw a png?
[21:06:55] <Tom_itx> jdhnc i would call them
[21:07:11] <Tom_itx> the mt2 bothers me a bit
[21:07:22] <Tom_itx> the drawbar helps
[21:07:42] <jdhnc> I have an r8 mill
[21:07:53] <Tom_itx> ok
[21:08:02] <Tom_itx> doesn't use bp collets?
[21:08:43] <jdhnc> I have a set of R8 collets, but to change them, you need a lot of Z room
[21:09:07] <Tom_itx> well yeah
[21:09:49] <jdhnc> I have an MT3 mill also (never used) that I could just get the mt3 arbor for
[21:11:50] <Tom_itx> if you get a set would it matter that they're ER?
[21:12:11] <Tom_itx> they look like it but..
[21:12:23] <jdhnc> no, only in that I would like to be able to get a matching collet holder for my other mill to share the collets
[21:12:47] <Tom_itx> i'd just call em
[21:14:01] <jdhnc> I sent them an email. I've impulse bought enough stuff this week.
[21:14:14] <ReadError> http://www.youtube.com/watch?v=pquiohEcamw&feature=plcp&context=C498f0f3VDvjVQa1PpcFPbUL-GhX6iZGUSGOozqxynljokN1Lh7uw%3D

[21:14:35] <jdhnc> woohoo!
[21:14:39] <ReadError> ;oooooo
[21:14:43] <ReadError> i need a stiffer tip
[21:14:49] <ReadError> im doing another one right now ;)
[21:14:50] <jdhnc> I hear that a lot
[21:15:01] <Jymmm> ReadError: viagra?
[21:15:04] <jdhnc> you need to upgrade emc
[21:15:05] <ReadError> cardboard isnt too flat either
[21:17:12] <alex4nder> ReadError: congrats
[21:18:09] <Tom_itx> ReadError wow! 2 in one night?
[21:20:30] <ReadError> i want to do "wtf jackie chan"
[21:20:38] <ReadError> not sure how well it would convert to gcode

[21:24:55] <ReadError> awwwww yea
[21:24:59] <ReadError> let me get my flash drive
[21:25:54] <Tom_itx> jdhnc what do you use for txt?
[21:26:33] <jdhnc> that was DeskEngrave
[21:27:17] <jdhnc> but usually cad + cut2d or just simple stuff directly in cut2d
[21:37:35] <ReadError> these 1-2-3 blocks are awesome
[21:37:55] <jdhnc> they're as easy as 1-2-3!
[21:38:50] <toastydeath> wait till you see 2-4-6 blocks!
[21:39:03] <jdhnc> they are surpsingly pricy
[21:39:14] <toastydeath> we always made that kind of thing on our own
[21:39:26] <toastydeath> everyone in the shop had a pair of bigass parallels
[21:39:58] <toastydeath> 12" long, 1/5
[21:40:15] <toastydeath> er, 1/2" wide and just under whatever the standard kurt vice jaw is tall
[21:40:23] <toastydeath> i think it gave 1/8th of jaw
[21:41:18] <ReadError> i got 4 blocks for 20$ i think
[21:41:30] <jdhnc> 123's are usually really cheap
[21:43:18] <ReadError> http://s3.amazonaws.com/ragefaces/3fa9aa4e19889110c01bae7601d70e25.png
[21:43:24] <ReadError> can you do that jdhnc
[21:43:32] <ReadError> like no larger than 3-4"
[21:43:47] <ReadError> getting some crazy stuff with the import in EMC
[21:43:55] <jdhnc> Read: how crazy?
[21:44:13] <ReadError> like a bunch of lines
[21:44:29] <ReadError> trying again with some different settings now
[21:44:56] <ReadError> on the bright side, 1 more day of work!
[21:45:07] <jdhnc> using a pen?
[21:45:10] <jdhnc> what's the tip size?
[21:45:16] <ReadError> unfortunately i have to wake up in about 5.5 hours
[21:45:19] <ReadError> its a sharpie
[21:45:27] <jdhnc> 1/16"?
[21:45:30] <ReadError> sure
[21:45:34] <ReadError> that sounds about riight
[21:54:23] <jdhnc> that was a bust
[21:54:34] <jdhnc> way too painful to play with for long.
[22:10:20] <ReadError> do you have a copy ?
[22:10:24] <ReadError> or is it payware?
[22:10:39] <jdhnc> of what?
[22:11:15] <ReadError> deskengraver
[22:11:27] <jdhnc> google it, it's free (windows)
[22:11:35] <jdhnc> or try fengrave
[22:12:57] <ReadError> is there something simple that converts monochrome images to toolpath?

[23:36:49] <alex4nder> ReadError: hey, it's not a requirement, but I think you need some more gap in your couplers
[23:37:41] <alex4nder> it might be worth checking.
