[00:35:42] <r00t4rd3d> or in my case, bb gun
[02:17:09] <DJ9DJ> moin
[07:17:03] <UncleG> I see the room is getting more and more people every time I return. :)
[07:23:23] <jthornton> put your safety glasses on... it's grapefruit time
[07:23:41] * Tom_itx puts up a blast shield
[07:23:59] <DJ9DJ> hrhr
[07:25:10] <Tom_itx> kinda reminds me of gallagher
[07:26:57] <jthornton> its not that bad... but I do cover the keyboard

[07:37:08] <ProxDem> jthornton: lol
[08:07:34] <ReadError> anyone dealt with the warranty on a ShopVac ?
[08:10:26] <ProxDem> ReadError: have fun with the RMA form =)
[08:11:04] <jdh> do you have to ship it to them?
[08:11:18] <ReadError> i hope not ;/
[08:11:21] <ProxDem> not always sometimes they just ask you to cut the power cord and ship that
[08:11:23] <ReadError> its like 3 months old
[08:11:33] <ReadError> already dead ;/
[08:11:34] <ProxDem> but that's still shipping! (but not the entire thing)
[08:11:39] <ReadError> ill ship the cord
[08:11:55] <jdh> I got a new one around xmas, but I haven't even plugged it in yet
[08:11:58] <ProxDem> ReadError: what model did you have?
[08:11:59] <ReadError> but not the entire motor
[08:12:18] <ReadError> http://www.amazon.com/gp/product/B003XREJOK/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1
[08:12:57] <jdh> hm. I think that is the one I got. What's wrong with it?
[08:13:12] <ReadError> it tries to start
[08:13:17] <ReadError> then bogs down and dies completely
[08:13:26] <ReadError> i mean i did use the heck out of it
[08:13:32] <jdh> I should try mine out
[08:13:32] <ProxDem> sounds like it's clogged?
[08:13:40] <ReadError> ProxDem: i cleaned the filter
[08:13:52] <ReadError> i got the HEPA one
[08:13:56] <ProxDem> ReadError: and under the filter the ball?
[08:13:59] <ProxDem> ReadError: the small green one?
[08:14:09] <ReadError> http://www.amazon.com/gp/product/B000093HP2/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
[08:14:32] <ProxDem> oh you meant the filter heheh
[08:14:52] <jdh> mine might be the next size up
[08:14:53] <ProxDem> ReadError: the ball that moves up and down unther the filter
[08:15:25] <ProxDem> if you hold it down and start the machine does it still stop? (warning don't blame me if you hurt yourself trying this lol) =)
[08:15:56] <ReadError> ill give it a shot
[08:16:00] <ReadError> i already ordered another
[08:16:06] <ReadError> and a new filter...
[08:16:13] <ReadError> but it would be nice to have a spare
[08:16:14] <ProxDem> also if you've vacuumed alot of drywall without the special thing that goes on the filter
[08:16:18] <ProxDem> then it's probably dead
[08:16:25] <ReadError> well, g10 dust
[08:16:31] <ReadError> which is probably finer than drywall
[08:16:47] <ProxDem> ewww
[08:16:49] <ReadError> yea
[08:16:56] <ProxDem> well that might have done it in =(
[08:16:58] <ReadError> thats why its important for me to have another ;/
[08:17:14] <ReadError> anywho, i hope they will just let me send the cord in
[08:17:23] <ProxDem> I hope so 2
[08:17:27] <jdh> heh... I vacuumed a lot of drywall stuff with my old one. The filter ripped and blew stuff everywhere. I cleaned it repeatedly and it still blew dust out for a year
[08:17:34] <ReadError> mailing that is almost not worth while
[08:17:36] <ProxDem> jdh: hehehe
[08:17:46] <ProxDem> usualy you put a FOAM cover ontop of the filter for drywall
[08:17:57] <jdh> had one of those too
[08:18:06] <ProxDem> as for g10 and or laser toner that required an entire different setup
[08:18:21] <ProxDem> jdh: damn must have sucked when it hit the fan
[08:19:04] <ProxDem> ReadError: if you have a clean source of compressed air you could always try disloging stuck particles
[08:20:31] <ProxDem> as carbon fibre raises hell with electrical contacts
[08:21:28] <ReadError> yea i tried blowing it out
[08:21:34] <ReadError> i think its just burnt up
[08:21:51] <ReadError> i was thinking about making a "shopvac waterbong"
[08:21:58] <ProxDem> it's very likely it's blown out lol
[08:22:07] <ReadError> to pass the air through a bucket of water, then into the shopvac
[08:22:16] <ReadError> like a...bong
[08:22:24] <ReadError> sounds crazy but it just might work
[08:22:34] <ReadError> diffuse it so the water grabs as much as it can
[08:22:54] <ReadError> or is that just a bad idea?
[08:23:01] <ProxDem> ReadError: you could reuse the canister to make a cyclone dust collector
[08:24:10] <ReadError> if i can trap most of the dust before it hits the filter it should make cleaning much easier
[08:24:38] <ProxDem> yeah
[08:24:44] <ProxDem> cyclone dust collectors aren't 2 bad at that
[08:25:12] <ReadError> never heard of them
[08:28:51] <r00t4rd3d> http://breakoutjs.com/
[08:51:07] <ProxDem> ReadError: you should really check it out then =)
[08:51:54] <ProxDem> ReadError: https://www.youtube.com/watch?v=GqGtyCthVQs <-- cheap homebuilt version
[08:53:50] <ProxDem> ReadError: if you want to see how some are made https://www.youtube.com/playlist?list=PL1ABF2C513E0F4838
[08:55:01] <ReadError> hmmm ill need to check in to this
[08:55:08] <ReadError> better than killing vacuums
[09:00:40] <alex_joni> question: if someone sells a GPL webapp (source only), is it legal to download the source from somewhere else?
[09:02:12] <carper64> i have a set of plans somewhere for a cyclone system from shop notes magazine
[09:06:56] <carper64> issue 13 volume 3
[09:09:21] <ProxDem> ReadError: yes they are very nifty at saving filters/bags and vacuums =)
[09:10:10] <carper64> yes very
[09:11:19] <ReadError> it would be worth while if i dont have to clean my filter every day
[09:14:20] <carper64> this one in shop notes uses a wooden framed box covered in cloth with a dust draw at the bottom the whole box is the filter mine used to be 3ft x 6ft
[09:14:52] <skunkworks> r2E, You're bevins - aren't you?
[09:19:40] <ProxDem> 9:57 AM - ecube [Wazu]: hai pixelized
[09:19:40] <ProxDem> 9:56 AM - Pixelized_[Wazu]: heya ecube
[09:19:40] <ProxDem> 9:57 AM - Pixelized_[Wazu]: wait wth
[09:19:40] <ProxDem> 9:57 AM - Pixelized_[Wazu]: steam you're on crack
[09:19:58] <ProxDem> ermm sorry about that...damn right click
[09:21:58] <ProxDem> just under the line numbers for irssi to popup a warning =(
[09:23:21] <ReadError> A no charge order #xxxxxxxxhas been entered for your new replacement power unit #xxxxxx on your Model 86ST450. This power unit is the motor, housing, switch and cord all assembled. Your order should arrive in 7 to 10 business days by FED EX. We do not have a breakdown of our power units, when something becomes defective we replace the complete power unit. Do not dispose of anything until
[09:23:21] <ReadError> you have received this order and replaced the defective one.
[09:23:21] <ReadError> You may need a “star” screw driver or bit #T25 to remove the screws from the bottom of the lid cage. Take the entire top off of the tank and flip it upside down. Remove the screws and take off the lid cage. Remove the defective power unit and replace it with the new one. Replace the lid cage and the screws. You may then dispose of the defective power unit.
[09:23:24] <ReadError> ;o
[09:24:02] <ProxDem> well damn
[09:24:08] <ProxDem> don't even need to send the powercord
[09:24:12] <ProxDem> shopvac +1
[09:29:19] <ReadError> yea i can just toss it out, or try to fix it ;)
[09:29:27] <ReadError> good guy shopvac!
[09:30:27] <ProxDem> that's really nice I'm glad it's working out for you =)
[09:31:05] <ReadError> yea, now ill have 2
[09:31:14] <ReadError> should help me keep them in rotation a bit better
[09:35:39] <carper64> i think the best idea is train the wife to clean and tidy the workshop after use
[09:39:47] <JT-Shop> dang one stick of the new ddr3 memory is bad...
[10:05:58] <ProxDem> JT-Shop: damn that's a bummer
[10:08:53] <JT-Shop> yea, I have to pay shipping back
[10:09:26] <ProxDem> argh that's not fun
[10:09:32] <DJ9DJ> payback time?
[10:28:34] <tjb1> ReadError: What is the green part?
[10:45:55] <ReadError> tjb1: the 3d printed one?
[10:46:01] <tjb1> yes
[10:46:07] <ReadError> an antenna jig
[10:46:16] <ReadError> cloverleaf/skewplanar antenna
[10:46:16] <tjb1> ah alright
[10:46:20] <ReadError> geometry is very important
[10:46:25] <tjb1> I seen the 108 degree on it
[10:46:35] <ReadError> it came out nice
[10:46:39] <ReadError> using the new slic3r
[10:49:53] <tjb1> I should be able to play with the printer today
[10:50:02] <tjb1> hopefully the extruder isn't going to act up
[10:50:16] <tjb1> I might make an airtripper but I don't think that is going to solve the problem
[10:50:52] <tjb1> I think the gear drive may be too agressive and the contact point so small that it is the reason I keep stripping the filament
[10:51:47] <ReadError> you hear about Good Guy Shopvac tjb1?
[10:51:52] <tjb1> no
[10:51:53] <ReadError> my motor burned out
[10:51:59] <ReadError> put a warranty thing in
[10:52:05] <ReadError> they are sending me a new top
[10:52:13] <tjb1> this a new machine?
[10:52:14] <ReadError> and i dont even have to send the old one back!
[10:52:19] <ReadError> shopvac
[10:52:21] <ReadError> vacuum
[10:52:24] <tjb1> yeah
[10:52:25] <tjb1> new?
[10:52:30] <ReadError> 4 months or so
[10:52:39] <ReadError> but it saw some heavy use
[10:52:41] <tjb1> we have one that is probably close to 10 years old
[10:52:54] <tjb1> it runs for hours connected to our sand blasting cabinet :P
[10:53:00] <ReadError> it ran for long periods, with the HEPA
[10:53:03] <tjb1> http://store.qu-bd.com/product.php?id_product=18
[10:53:07] <ReadError> G10 dust probably killed it
[10:55:11] <tjb1> What filament are you using?
[10:57:10] <ReadError> printbl
[10:57:15] <ReadError> hes got the best stuff around

[11:01:00] <tjb1> alibaba?
[11:01:08] <tjb1> aliexpress? I dunno
[11:01:16] <ReadError> alibaba is like a fleamarket in china website

[11:18:32] <syyl> jep r00t4rd3d
[11:18:44] <syyl> to both, granite and air
[12:05:54] <L84Supper> a nice GGG extruder and ceramic nozzles would be nice if somebody made them
[12:08:38] <chopper79> Need some help editing a .comp file for linuxcnc. Ho wdo I go about getting the .comp file to an editable state?
[12:08:58] <chopper79> I can find the module but it is .ko file
[12:11:42] <IchGuckLive> hi all B)
[12:15:46] <skunkworks> chopper79, it would be in the src directory
[12:16:07] <skunkworks> are you installed or rip?
[12:31:51] <chopper79> I need to modify the thc.comp file for a project im working on. I need to modify what inputs im routing or functions im routing to. I can find the .KO file, but I am not able to modify this to make the changes I need. Is there a place I can find the raw component to modify then install through terminal
[12:32:36] <skunkworks> I am not an expert on this... I don't know if you have the source in the installed version...
[12:32:38] <IchGuckLive> chopper79: git
[12:33:01] <chopper79> I have source installed
[12:33:08] <chopper79> I will try git
[12:33:08] <IchGuckLive> chopper79: there is a thc up down component 2
[12:33:15] <skunkworks> will it write over the installed compiled version of the thc?
[12:33:26] <IchGuckLive> for parport interact on 2 pins
[12:33:55] <chopper79> The thcud will not work for me I need to be using thc
[12:34:12] <IchGuckLive> components always overriugt etch other on install
[12:34:20] <chopper79> i am intergrating with a mesa card.
[12:34:21] <IchGuckLive> but on update it will come back
[12:34:48] <ProxDem> syyl_ws: nice measuring setup
[12:35:04] <IchGuckLive> chopper79: did you see jt's version
[12:35:16] <skunkworks> chopper79, http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=blob;f=src/hal/components/thc.comp;h=28dfd2c086e425af648fbad988cac1ea90391b87;hb=HEAD
[12:35:23] <IchGuckLive> chopper79: http://gnipsel.com/shop/plasma/plasma.xhtml
[12:35:51] <IchGuckLive> he uses 7i43
[12:35:52] <chopper79> I did, but the comp I see on his page is the up/down and I need the thc only version
[12:36:10] <IchGuckLive> there is a thxc 2
[12:36:49] <chopper79> Thanks skunk that looks to be the origanal one.
[12:37:01] <chopper79> Ich- so there is athc2 now?
[12:37:05] <chopper79> thc2
[12:37:19] <IchGuckLive> yes he did the mesa
[12:37:51] <chopper79> Im using the 5i25 and the THCAD-300
[12:38:15] <chopper79> is the THC2 a better canidate to just the thc
[12:39:27] <syyl_ws> thank you, ProxDem :D
[12:40:51] <IchGuckLive> chopper79: 5i25 + 7i76
[12:41:05] <IchGuckLive> or 7i77
[12:41:42] <chopper79> Just 5i25 and using a different BOB
[12:43:49] <IchGuckLive> did you modyfy the thcad300
[12:44:02] <chopper79> I was needing to route the output of the THCAD to an in input on the 5i25
[12:44:19] <chopper79> No modification the thcad300
[12:44:27] <IchGuckLive> ok
[12:45:52] <chopper79> I need to find the encoder A input on my 5i25 now
[12:46:10] <chopper79> How do you go to debug to see all the piouts of the 5i25 board
[12:46:18] <chopper79> if I asked that correctly
[12:46:40] <IchGuckLive> halcomand
[12:46:55] <IchGuckLive> loadfirmware and type show
[12:47:21] <IchGuckLive> is it a THC300 or a THCAD 300
[12:47:32] <chopper79> THCAD-300 from MESA
[12:47:36] <IchGuckLive> from where eagleplasma
[12:47:42] <IchGuckLive> ah
[12:47:53] <IchGuckLive> 0-10 or 0-300 version
[12:48:00] <chopper79> 300 version
[12:48:18] <chopper79> so in terminal I type halcommand?
[12:48:47] <IchGuckLive> http://linuxcnc.org/docs/html/man/man9/thc.9.html
[12:49:20] <IchGuckLive> did you read this
[12:49:24] <chopper79> Yes
[12:51:02] <IchGuckLive> so JT's thc is made that way
[12:51:07] <chopper79> yes
[12:51:09] <IchGuckLive> as he did the mesa modification
[12:51:11] <chopper79> from what I can see
[12:53:00] <chopper79> to see the pinout of the mesa card I have to go in terminal correct
[12:53:37] <IchGuckLive> yes
[12:53:49] <chopper79> type halcommand
[12:54:12] <chopper79> says command not found
[12:54:59] <chopper79> new to terminal so I dont know all the commands and lingo
[12:55:14] <IchGuckLive> let me find the right way
[12:56:32] <cpresser> chopper79: try 'halcmd'
[12:57:08] <IchGuckLive> chopper79: halrun -v
[12:57:25] <IchGuckLive> halcmd: is the output
[12:57:28] <chopper79> that worked. I forgot about the short hand
[12:57:51] <IchGuckLive> you need to run the hal first
[12:58:18] <IchGuckLive> then just load as rt as you do in the hal file
[12:58:39] <IchGuckLive> then after you loaded the board
[12:58:43] <IchGuckLive> loadusr halmeter
[12:58:43] <chopper79> used halrun -v and came back as realtime already running
[12:58:55] <IchGuckLive> ok
[13:00:28] <chopper79> ok.. im lost I can not find anything.
[13:00:47] <chopper79> Is the hal meter the same as the one in linuxcnc when its loaded?
[13:01:25] <IchGuckLive> yes
[13:01:34] <IchGuckLive> you nedd to load the cadr first
[13:01:42] <IchGuckLive> the 5i25
[13:03:39] <R2E4_> Hi all.
[13:03:40] <IchGuckLive> chopper79: did you look at the ready done configs in linuxcnc 2.5.2 there is a thc300 mashine in
[13:04:17] <R2E4_> the spindle motor on my R2E4 says 60 amps at 220v @ 3phase.
[13:04:34] <R2E4_> that dowsn't mean I have to have a vfd that will handle 60 amps?
[13:04:39] <R2E4_> Thats nuts.
[13:05:20] <chopper79> yes- but they are for the bob campbell thc if I am not mistaken
[13:07:13] <AR__> cheap linuxcnc computers? http://www.ebay.com/itm/IBM-Lenovo-M52-Celeron-D-2-8GHz-1GB-RAM-40GB-HD-CD-ROM-8215-A2U-S-/321093719090?pt=Desktop_PCs&hash=item4ac2ad5432
[13:07:51] <IchGuckLive> AR__: the A50 is mutch faster at 2GB for 50Eur
[13:07:51] <archivist> R2E4, for 20+ hp that sounds right ish
[13:08:33] <archivist> R2E4, http://www.engineeringtoolbox.com/elctrical-motor-full-load-current-d_1499.html
[13:11:40] <R2E4_> ha, why does the motor say 220v 60 amps?
[13:12:16] <archivist> what is its HP rating
[13:12:22] <R2E4_> bizarre. OK I am good then according to that doc and my research. The label on the mill motor was disturbing.
[13:12:27] <R2E4_> 2HP
[13:12:44] <archivist> decimal point
[13:13:28] <archivist> 6.0 amps I bet
[13:14:36] <R2E4_> yeah its there. I thought someone threw a dart at it or something. I freaked when I read 60....hehe
[13:21:39] <IchGuckLive> R2E2 http://www.automationdirect.com/adc/Overview/Catalog/Drives/GS2_%28115_-z-_230_-z-_460_-z-_575_VAC_V-z-Hz_Control%29
[13:21:50] <IchGuckLive> R2E4 B)
[13:22:03] <IchGuckLive> 160USD
[13:22:18] <andypugh> I think I might try making magsafe connector for my newly-arrived Renishaw probe.
[13:22:48] <andypugh> It came with an inductive transmitter, but that only really makes sese with a toolchanger, and I don't know how it works either.
[13:22:57] <IchGuckLive> R2E4 there is a comp for this vfd so it is easy to get it into your ini
[13:31:07] <pcw_home> chopper79: if you dont know what pins are available, launch linuxcnc and then from a terminal type:
[13:31:09] <pcw_home> halcmd show pin > pinlist.txt
[13:31:11] <pcw_home> or
[13:31:12] <pcw_home> halcmd show param > parmlist.txt
[13:40:59] <chopper79> pcw-home, I did that and the list is shown.
[13:44:20] <chopper79> So I now have my list and shows all the pins. There ia nothing listed as encoder A. The only encloder I see in the list is hm2_5i25.0.0encoder.00.
[13:44:40] <pcw_home> There is no encoder A
[13:44:41] <chopper79> Would it be safe to assume that there is no encoder A
[13:45:19] <pcw_home> the signal you need from the encoder is the velocity
[13:48:22] <chopper79> So from this point how do I know which encoder input on the 5i25 goes to which pin on the DB25 connector
[13:48:41] <chopper79> so I can run the THCAD-300 to this pi
[13:48:46] <chopper79> pin
[13:50:17] <andypugh> chopper79: I think there may be a clue in dmesg
[13:50:52] <chopper79> ok, can you explain how to get to dmesg please?
[13:50:58] <andypugh> Something like Apr 4 01:15:36 DN2800 kernel: [85938.692704] hm2/hm2_5i25.0: IO Pin 021 (P2-03): StepGen #7, pin Direction (Output)
[13:51:05] <pcw_home> yes. As I had mentioned before you set the encoder counter to up/down mode but with the standard pinout (that assumes a quadrature spindle encoder), this wastes the B pin (since it must be tied high or low to avoid the velocity reversing)
[13:51:14] <andypugh> just type dmesg in the terminal
[13:52:33] <andypugh> chopper79: Which version of the 5i25 do you have, which daughter board, and which encoder do you want to use? I have the info in a terminal in front of me.
[13:52:55] <chopper79> 5i25 with the pbx-rf flash
[13:53:53] <pcw_home> you probably want pbx-rf-plasma (no B or Index pins)
[13:54:16] <chopper79> so there is a pbx-rf plasma?
[13:54:34] <pcw_home> not yet
[13:54:55] <pcw_home> its about 5 minutes of work
[13:55:33] <chopper79> Well considering I can not even do the simple tasks of finding a encoder pinout. It may become 5 days of work
[13:56:22] <chopper79> I figured this would be somwhere along the lines of encoder# goes to pin number 13 on a db25 cable
[13:56:42] <pcw_home> there are 3 sources of pinout information
[13:56:44] <pcw_home> one that always works is the listing in dmesg
[13:57:30] <chopper79> in dmesg I see the following
[13:57:37] <pcw_home> Another option is the probrf2x2.pin file available in the 5i25.zip file from mesa
[13:58:09] <chopper79> io pin 014 (p3-11): encoder #0, pin A (input)
[13:58:47] <chopper79> I for some reason or another do not have a hostmot firmware folder for the 5i25 with the pin files in it
[13:59:00] <chopper79> I see the defaults that come with linuxcnc
[13:59:18] <chopper79> I do have the .xml files in the proper folders
[13:59:56] <pcw_home> the xml files are only for pncconf
[14:00:12] <chopper79> ok that explains that one
[14:00:46] <chopper79> do I need the pin files as the others have that are default in linuxcnc
[14:01:28] <pcw_home> They are only for your information
[14:01:48] <chopper79> ok, that is what I was thinking
[14:02:01] <pcw_home> I like the dmesg printout better as there no chance of a mis-match
[14:03:19] <pcw_home> now if the driver just made the xml file for pncconf, everything would be automagic
[14:03:46] <chopper79> since dmesg shows io pin 014 (p3-11): encoder #0, pin A (input) how do I know which pin that is on the db25 output?
[14:03:57] <chopper79> automagic... nice
[14:04:26] <chopper79> or do I use hal meter and find it?
[14:04:44] <pcw_home> It says: (P3-11)
[14:06:07] <r00t4rd3d> these would work as mini estops right?
[14:06:09] <r00t4rd3d> http://www.ebay.com/itm/250973270098?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
[14:07:28] <chopper79> correct
[14:09:25] <pcw_home> r00t4rd3d: not ideal
[14:09:26] <pcw_home> Most likely NO, you want NC for estop
[14:10:05] <r00t4rd3d> i cant remember how i have my current estop set
[14:10:46] <r00t4rd3d> those push buttons - Circuit: SPST-NO
[14:10:56] <pcw_home> NC so a broken wire causes an EStop rather than just disabling the button
[14:12:53] <pcw_home> on a tiny machine it probably doesn't matter
[14:12:55] <chopper79> pcw- so what does the (P3-11) mean? Is this Pin 3-11?
[14:13:15] <r00t4rd3d> i have a tiny machine
[14:13:27] <r00t4rd3d> kinda 12x25 cut area
[14:14:45] <r00t4rd3d> what if i tapped into the nc wire on my current estop and attached that to both terminals on the push button....
[14:15:22] <tjtr33> Plug3Pin11 look at the manual and loof for the connector id's and where pin 1 is
[14:15:29] <tjtr33> look
[14:15:30] <chopper79> pcw-ok so IO pin 014 = pin 11
[14:15:39] <chopper79> just made that connection
[14:15:56] <andypugh> Hmm loadrt hm2_pci "firmware=new_firmware, create_xml=true"?
[14:16:46] <pcw_home> the dmesg is close...
[14:16:57] <r00t4rd3d> damn i got limit switches i could probably rig another estop out of...
[14:17:45] <tjtr33> cubieboard in from HongKong :) , but gotta pack and leave Sat :(
[14:18:04] <chopper79> alright so now I would take my FO+ and FO- from the THCAD300 and take one of them to pin 11 pn the P3 connector. This should link my frequancy out of the THCAD300 to the input in the config file?
[14:18:14] <chopper79> frequency
[14:18:27] <pcw_home> just use F0+
[14:18:31] <chopper79> ok
[14:18:41] <pcw_home> or FO-
[14:18:50] <pcw_home> makes no difference
[14:19:54] <r00t4rd3d> normally closed means everything is connected right? the button push causes a break triggering the estop?
[14:20:04] <pcw_home> Yes
[14:20:46] <pcw_home> for the same reason its suggested that limit switches be NC
[14:23:42] <tjtr33> i like 'security link' or 'safety chain', if you break the link or chain, the system is not safe/secure, so STOP.
[14:23:44] <tjtr33> the word 'Estop' doesnt convey this simple clear idea
[14:24:26] <tjtr33> potato potatoe
[14:24:33] <chopper79> let me give this a shot real quick after I redo the thc.comp file
[14:25:45] <tjtr33> maybe try it before changing the comp?
[14:25:49] <tjtr33> wont take long
[14:33:43] <r00t4rd3d> http://gtocs.blogspot.com/2012/04/garys-diy-cnc-touch-probe.html
[14:33:50] <r00t4rd3d> thats seems simple
[14:52:32] <chopper79> well I can not see the input from the THCAD300 in the hal meter. I should be able to go into the hal meter and check the status of the input pin to see the frequency in correct?
[14:54:37] <t12> cool
[14:54:44] <t12> i found a big pile of stellite j at work
[14:55:06] <pcw_home> the encoder velocity pin yes hm2_5i25.0.encoder.00.velocity
[14:55:47] <chopper79> correct and it shows no change when applying an input voltage
[15:01:16] <pcw_home> reads 0?
[15:01:36] <chopper79> yes
[15:01:41] <pcw_home> what is the encoder scale?
[15:01:57] <pcw_home> and does the THCAD have 5V power?
[15:02:44] <pcw_home> and is the encoder set to up/down mode
[15:02:58] <chopper79> Has 5v
[15:03:08] <chopper79> I am not sure about the other two questions
[15:03:41] <chopper79> Not sure where to check that at
[15:04:25] <pcw_home> HAL file
[15:04:34] <chopper79> thats where i was just checking
[15:05:12] <chopper79> the scale offset is 119000
[15:05:59] <chopper79> I also see counter mode 1, woudl this be the mode for up/down
[15:06:47] <chopper79> there is a vel. scale also of 0.0037866834
[15:07:06] <pcw_home> OK thats correct (if its setp hm2_5i25.0.encoder.00.countertmode 1)
[15:07:46] <chopper79> yes thats correct
[15:09:16] <chopper79> im using a lower voltage to test with at this mon=ment so could the scaling be wrong for my voltage?
[15:09:45] <pcw_home> encoder velocity should read something if
[15:09:47] <pcw_home> THCAD has power
[15:09:47] <chopper79> using 37v at the moment to test on my desk. Dont want to hook a plasma up to my equipment on my desk
[15:09:48] <pcw_home> THCAD FOUT wiring is right
[15:09:50] <pcw_home> encoder in up/down mode
[15:10:09] <chopper79> Let me double check everything
[15:10:58] <pcw_home> should make no difference, even with no input the velocity from the encoder counter should read something (0 offset frequency)
[15:11:08] <chopper79> encoder.00.counter-mode 1
[15:11:20] <chopper79> 5v to THCAD , both LED are on
[15:11:37] <chopper79> 36v dc goin to IN- and IN+
[15:11:59] <pcw_home> bbl
[15:11:59] <chopper79> FO+ going to pin 11 on 5i25

[15:27:45] <Connor> Out of wood?
[15:27:56] <Connor> Go get some HDPE or something.
[15:28:28] <r00t4rd3d> why softer plastic?
[15:28:46] <Connor> more stable. not subject to moisture.
[15:29:16] <PCW> DB25 pin 11 on P3?
[15:32:43] <roh> r00t4rd3d: nice model. i still need a 3d-probe also.
[15:33:19] <r00t4rd3d> http://gtocs.blogspot.com/2012/04/garys-diy-cnc-touch-probe.html
[15:34:49] <roh> r00t4rd3d: i dunno if i want to build it myself. lots of work to make a good one which is centered etc
[15:36:03] <r00t4rd3d> im all skill.
[15:36:54] <r00t4rd3d> if it dont work ill smash it with a mallet i finished today :)
[15:37:59] <r00t4rd3d> im just gonna use 16penny nails :)
[15:41:04] <LeelooMinai> http://snbinc.ca/site/wp-content/images/components/zaxis/zaxis_7.png <- I have a basic fastener question. In the picture they use counterbore for the cap screws. If one uses longer screws and no counterbore, how would it affect the joining? Would it weaken/strengten it?
[15:42:00] <r00t4rd3d> i doubt it, looks like they sunk them just for the motor mounts
[15:42:39] <LeelooMinai> I guess my question is general - in situarions like that, what would make the whole structure stiffer? Couterbore or not?
[15:43:17] <LeelooMinai> Assuming one does not care about caps of the screws sticking out that is
[15:43:36] <r00t4rd3d> i dont think either way would matter
[15:44:28] <LeelooMinai> Hmm... I was thinking that couterbore removes some material from the plate... so maybe that's weaker... but not sure.
[15:49:56] <gabewillen> Am i doing this math right? if have a base thread of 25000ns(40000hz), and a 7200cpr encoder(28800 ppr). divide the hz/ppr to give a max theoretical rotations per second?
[15:53:20] <r00t4rd3d> LeelooMinai, microcarve makes them the same way:
[15:53:20] <r00t4rd3d> http://www.cnczone.com/forums/diy_cnc_router_table_machines/109390-my_newest_desktop_machine-142.html#post1240843
[15:53:51] <r00t4rd3d> bette pics http://www.microcarve.com/ebayz35ext2/
[15:54:12] <r00t4rd3d> he sells those for $159 + $12 shipping
[15:54:42] <chopper79> PCW- correct I am connected to pin 11 on the db25 connector
[15:59:24] <chopper79> I have bypassed any other potential item between the THCAD FO+ and the DB25 connector in the 5i25. Wired directly it still shows no freq on encoder.00.velocity
[16:08:51] <roh> hm. so there is only one bearing on those spindles?
[16:09:06] <roh> and the other end just swings free.. seems kinda cheap
[16:09:42] <r00t4rd3d> i have my z like that too
[16:10:54] <roh> i like the mechanical setup elsewise... i am searching for some mill like this one, but made from aluminium and with ballbearing-spindles
[16:10:57] <roh> http://www.microcarve.com/mcMV1.html
[16:11:36] <tjtr33> gabewillen, imo if the encoder counter is 'on' the base thread, and it can only count 1 edge per thread cycle, then yes.
[16:11:38] <r00t4rd3d> he posted the plans for that online for free
[16:11:39] <tjtr33> but maybe you're on the servo thread and maybe you have hardware counter that you can look at each thread cycle.
[16:12:01] <roh> r00t4rd3d: yeah, but i got no mill big enough to make the parts
[16:12:17] <r00t4rd3d> http://www.cnczone.com/forums/diy_cnc_router_table_machines/134221-microcarve_mv2_plans_files.html
[16:12:35] <roh> ours is only ~200mm x 110mm x 150mm x y z moving area
[16:14:15] <r00t4rd3d> he swears by those solid brass couplers
[16:14:39] <r00t4rd3d> great
[16:14:42] <Loetmichel> re @ home
[16:15:25] <roh> meh. i want ball-bearing ;). and real couplers. thats nothing to be cheap upon
[16:16:31] <r00t4rd3d> he mills pcbs and metal/aluminum with those.
[16:19:06] <r00t4rd3d> and most of the frame is mdf
[16:21:19] <Loetmichel> mdf for a mill frame is a bad choice
[16:21:27] <tjtr33> gabewillen, also "It also exports two functions. 'encoder.update-counters' must be called in a high speed thread, at least twice the maximum desired count rate"
[16:21:41] <tjtr33> and suggests using hdwr if you need better performance
[16:22:51] <Connor> Loetmichel: http://www.ivdc.com/cnc/cnc13.JPG
[16:22:54] <Connor> Mine is MDF.
[16:23:37] <Loetmichel> Connor: mdf has the problem of being probne to dimension change with humidity change
[16:24:30] <Loetmichel> i make my mills from wood also, but i use "siebdruckplatte" (plywood with melamin as glue, not white glue)
[16:24:40] <Connor> Loetmichel: Yea, that's why you seal it.
[16:25:28] <Loetmichel> Connor: that helps only if the sealant can fill the whole mdf, not only the surface
[16:25:53] <Loetmichel> i.e. sink it in wather thin 2k Epoxy. THAT may help ;-)
[16:27:09] <DJ9DJ> gn8

[17:04:26] <JT-Shop> Tom_itx: your package showed up today :)
[17:08:05] <tjb1> JT-Shop: Good chance I'll be at Hardinge :)
[17:08:31] <JT-Shop> cool
[17:10:35] <JT-Shop> what will you be doing?
[17:12:54] <tjb1> manufacturing engineer
[17:13:04] <JT-Shop> neat
[17:15:45] <andypugh> r00t4rd3d: By a curious coincidence, I just got back down to the computer after stripping and cleaning an actual genuine Renishaw touch-probe.
[17:19:05] <r00t4rd3d> i will cut my prototype soon
[17:19:23] <andypugh> It was full of coolant residue, and all oily inside. It now _does_ trigger the continuity beeper on my multimeter.
[17:20:08] <andypugh> I should have taken photos, there are some interesting design features.
[17:21:17] <andypugh> There is a 3-slot insulator about 1" deep that the pins run in, that takes the torque when you tighten the probe.
[17:21:53] <andypugh> Next to the slots are 6 holes, these have gold-plated springs that press on the balls at the bottom, and the PCB at the top.
[17:23:26] <andypugh> I don't know how the balls are held. They appear to be glued into a bit of aluminium. Presumably rather carefully so that they don't make conductive contact with the alumnium
[17:24:46] <andypugh> I could afford this one, because somebody can't spell "Renishaw" :-)
[17:31:55] <JT-Shop> I think I have the 3-d cad of an older renishaw
[17:31:58] <r00t4rd3d> http://i.imgur.com/qQdO5Dq.jpg
[17:32:05] <r00t4rd3d> thats what i got so far
[17:33:07] <r00t4rd3d> the ring on the left is just in case i need more room :)
[17:34:00] <r00t4rd3d> will depend on the spring size i use i guess
[17:34:00] <andypugh> One huge error there..
[17:34:09] <r00t4rd3d> wood is good
[17:34:41] <andypugh> No problem with wood, wood I like.
[17:35:17] <r00t4rd3d> then whats the error?
[17:35:21] <andypugh> You have the wrong number of balls and rods.
[17:35:55] <r00t4rd3d> there was only 3 in the original design
[17:36:05] <andypugh> Yes, because 4 won't work.
[17:36:34] <andypugh> The three rods / 6 balls thing is the truly clever part of the original Renishaw patent.
[17:36:53] <r00t4rd3d> http://gtocs.blogspot.com/2012/04/garys-diy-cnc-touch-probe.html
[17:37:01] <andypugh> It is perfectly constrained, but not over-onstrained.
[17:37:21] <r00t4rd3d> thats how i am doing it, different then ren i believe
[17:37:47] <r00t4rd3d> looks for breaks in the contacts so it dont matter how many their are i dont think
[17:38:05] <andypugh> Well, he has his wored wrong too.
[17:38:10] <andypugh> (wired)
[17:38:38] <andypugh> As far as I can see he has to break A and either of B and C to get a probe.
[17:38:53] <andypugh> The contacts all go in series.
[17:39:11] <r00t4rd3d> http://2.bp.blogspot.com/-cIsKr-pWlOY/T4C3QVwZOzI/AAAAAAAAAEw/8tyS0dtNjT8/s1600/bottomView.JPG
[17:39:23] <r00t4rd3d> but the brass rods he uses rests on both screws
[17:40:19] <andypugh> Yes.
[17:40:22] <r00t4rd3d> so if either side lifts, its a break
[17:40:30] <r00t4rd3d> on any screw
[17:40:32] <andypugh> Not with his wiring.
[17:43:04] <r00t4rd3d> if the inside bars come off either b or c that are not connected only to each other, that will cause a break in the circuit
[17:43:41] <andypugh> No, because A is offering an alternative path.
[17:44:52] <r00t4rd3d> so how should it be wired?
[17:45:31] <andypugh> Wire to one A contact, and one B contact.
[17:45:58] <andypugh> so current flows through A, B and C and breaking any one stops the current.
[17:46:33] <r00t4rd3d> what if you only got 2 wires?
[17:46:51] <r00t4rd3d> how do you tie c in ?
[17:46:54] <andypugh> There should only be 2 wires.
[17:47:32] <r00t4rd3d> so 1 wire goes to both a screws, then 1 wire to both b screws
[17:48:03] <andypugh> The circuit is A1 bar to A2 link to B1 bar to B2 wire to C1 bar to C2 wire back to controller.
[17:48:07] <andypugh> (for example)
[17:48:37] <andypugh> Take out any bar, no contact.
[17:49:10] <r00t4rd3d> should i go back to 3 bars instead of 4?
[17:49:18] <andypugh> Absolutely definitely 100%
[17:49:24] <r00t4rd3d> damn
[17:49:25] <andypugh> 4 simply won't work.
[17:49:45] <andypugh> You can never get all 4 to make contact (unless something bends)
[17:49:59] <r00t4rd3d> i see what you mean now, if a is touching and b/c breaks it wont sense it
[17:50:12] <andypugh> Consider an infinitley stiff table on floor, compared to a three-legged stool.
[17:51:28] <andypugh> The 3-bar design really is very clever the way it absolutely centres the probe.
[17:52:14] <andypugh> My Renishaw has a spherical seat at the top and 4 mounting screws. The idea is that you can adjust the probe to make the ball run 100% true.
[17:52:46] <andypugh> By slackening one screw and tightening its partner you fractionally tilt the whole head.
[17:53:35] <PCW> isn't that one of those cheap Renshaw knock-offs
[17:54:43] <andypugh> If I was making a probe (and I did intend to, actually) I would use some of the many 2.5mm broken carbide milling cutters I have. It is better if the rods and balls have very little friction, so hard is good. (carbide does conduct).
[17:55:41] <andypugh> PCW: This is mine: http://www.ebay.co.uk/itm/Renshaw-Mp3-Probe-/271177751112
[17:56:01] <PCW> ya stole it
[17:56:21] <andypugh> If he can't spell "Renishaw" then it's his lookout :-)
[18:00:34] <alex_joni> andypugh: ask him to sell you 4 for the price
[18:00:47] <alex_joni> I mean pricex4
[18:07:43] <andypugh> Might be worth emailing the vendor.
[18:24:46] <andypugh> PCW: I am not sure that firmware works.
[18:25:29] <andypugh> I am getting a continuous 0x40 scancode.
[18:35:39] <PCW> We changed the way it works 0x40 is nochange 0x00 is all up
[18:39:34] <PCW> MSB is changed bit
[18:39:35] <PCW> so all deltas have MSB set
[18:39:37] <PCW> so 0b11XXXXXX is key X down
[18:39:38] <PCW> 0b10XXXXXX is key X up
[18:39:40] <PCW> 0b01000000 is no-op
[18:39:42] <PCW> 0b00000000 is all up
[18:40:32] <andypugh> But I have all-up..
[18:40:48] <andypugh> And how is a key-0 down shown?
[18:41:03] <PCW> 0xC0
[18:41:46] <PCW> key 0 up is 0x80
[18:41:57] <andypugh> Ah, OK.
[18:42:04] <andypugh> I need to change the component then...
[18:42:38] <andypugh> A job for tomorrow, it is now time to sleep
[18:42:41] <PCW> yeah anyone that uses the KB probably wants 2key rollover
[18:42:54] <PCW> 'nite
[18:43:07] <PCW> oops a bit late
[19:36:41] <jdh> http://wilmington.craigslist.org/tls/3719565720.html
[19:37:50] <jdh> I've got some small steppers and a spare tb6560, should be perfect for something.
[19:41:16] <Tom_itx> JT-Shop good news
[19:41:28] <JT-Shop> what's that?
[19:42:17] <Tom_itx> you got the package
[19:42:37] <JT-Shop> lol did the peeoff tell you that?
[19:42:49] <Tom_itx> no, i'm catching up on the logs
[19:43:21] <JT-Shop> ok
[19:43:36] <Tom_itx> you need a pinout for the 7805?
[19:43:48] <Tom_itx> in gng out
[19:43:53] <Tom_itx> gnd
[19:43:58] <JT-Shop> your tutorial looked ok
[19:44:20] <r00t4rd3d> i would love that lathe jdh, did you buy it?
[19:44:23] <JT-Shop> time for chow and to turn on the magnetass switch
[19:44:30] <jdh> tried to, no response
[19:44:59] <r00t4rd3d> 12v too you could use the tb6560 to run the motor
[19:46:08] <JT-Shop> goodnight all
[19:46:13] <Tom_itx> later
[20:41:19] <r00t4rd3d> jdh did you get a hold of that guy yet and buy me that lathe ?
[20:41:54] <jdh> emailed him twice
[20:42:10] <r00t4rd3d> prolly lots of people did
[20:42:17] <jdh> doubt it
[20:42:27] <r00t4rd3d> i would be on that
[20:42:31] <r00t4rd3d> 25 bucks?
[20:43:01] <jdh> they weren't that expensive new
[20:43:13] <jdh> yes send me your number and I will call
[20:44:00] <ProxDem> 25$ for a lathe?
[20:44:04] <jdh> 30 min drive from work
[20:44:05] <ProxDem> =P
[20:44:11] <jdh> toy lathe
[20:44:29] <r00t4rd3d> http://watertown.craigslist.org/for/3709477685.html
[20:44:37] <r00t4rd3d> thats what comes up on my list
[20:44:42] <r00t4rd3d> typical
[20:44:51] <jdh> heh
[20:44:59] <r00t4rd3d> a fucking doll house leg on it
[20:45:01] <jdh> this is a pretty isloated area.
[20:45:30] <jdh> relatively... ocean on one side, river on the other, swamps around there.
[20:45:49] <r00t4rd3d> its either garbage like that or stuff like this
[20:45:51] <r00t4rd3d> http://potsdam.craigslist.org/wan/3590903878.html
[20:45:56] <jdh> lots of transplanted new yorkers
[20:46:20] <jdh> that looks like some nice iron
[20:46:44] <r00t4rd3d> probably weights 8million pounds
[20:47:50] <Tom_itx> sell it for scrap then
[20:48:03] <jdh> there is an atlas and a south bend nearish here. too pricey though
[20:49:20] <jdh> http://tinyurl.com/cl64vxd I found those on craigslist. met the guy at a mcdonalds 100 miles from here while driving to florida

[21:11:09] <skunkworks> I think we will be cnc'ing our 10EE
[21:49:13] <tjtr33> skunkworks, did you notice the "using a program like Filtermax would help by converting all those small line segments to arcs." on that page?
[21:49:18] <tjtr33> theres been some interest here for similar ( but not likely OpenSource :( )
[21:49:38] <tjtr33> yeck, even uglier, no price listed and wants you to 'join' to find price nanananana
[22:23:24] <skunkworks> we use bezarc at work..
[22:23:55] <skunkworks> for 2d stuff - I don't know if it will do 3d..
[22:24:26] <skunkworks> we use it to convert ai files to dxf using arcs instead of short lines
[22:29:26] <tjtr33> ah , kandu software and adobe illustrator. thx
[22:31:40] <tjtr33> i was getting too deep into Pythagorean-hodographs which is a way to get tangential arcs thru a set of points ( drowning! )
