[02:21:50] <Loetmichel> mornin'
[02:22:42] <Jymmm> mornin
[04:12:11] <DJ9DJ> moin
[07:07:05] <r00t4rd3d> JT-Shop, TADA!
[07:07:17] <r00t4rd3d> sorta
[07:07:38] <jthornton> he ain't out there yet
[07:08:03] <r00t4rd3d> err where ever you are
[07:13:18] <tjb1> Too early for this r00t4rd3d
[07:14:47] <alex_joni> morning r00t4rd3d
[07:16:14] <r00t4rd3d> :D
[07:16:17] <r00t4rd3d> looks good
[07:17:53] <tjb1> I went from cnczone to a spud gun website to an obituary…I hate the internet
[07:19:54] <tjb1> Now im on like a german death metal band site because I looked up obituary in google :/
[07:20:05] <r00t4rd3d> Has the Karma and Thank You always been on the forums?
[07:21:07] <tjb1> cnczone?
[07:21:51] <r00t4rd3d> no linuxcnc
[07:23:03] <tjb1> Off to pick up my metal
[07:23:18] <r00t4rd3d> shouldnt you be in school?
[07:23:21] <jthornton> the karma has
[07:24:43] <tjb1> No r00t4rd3d, I only have school twice a week...
[07:25:14] <r00t4rd3d> Ahh the cuts to the special education funding
[07:25:19] <r00t4rd3d> bummer
[07:25:48] <tjb1> Says the one that put a 1" knob on a box 4" wide :)
[07:25:59] <r00t4rd3d> 7 3/4 inch wide
[07:26:10] <tjb1> Yeah I said 4" wide
[07:26:26] * r00t4rd3d rubs the 75 bucks in his pocket
[07:26:44] <tjb1> Are you sure thats the 75 bucks?
[07:26:57] <r00t4rd3d> maybe its my 1" knob
[07:27:16] <tjb1> That only fits 4" wide boxes?
[07:27:45] <r00t4rd3d> I just finished another box last night
[07:28:25] <r00t4rd3d> http://imgur.com/a/4XSZG
[07:28:38] <tjb1> Yeah I seen it last night
[07:28:46] <r00t4rd3d> looks different now, I stained the letters.
[07:29:07] <tjb1> So why do you show me the same picture as last night?
[07:29:20] <r00t4rd3d> cause i havent taken new ones yet
[07:29:26] <r00t4rd3d> waiting for the sun to come out
[07:29:27] <tjb1> Well get to work...
[07:29:31] <tjb1> Suns up here
[07:30:26] <tjb1> im out.
[08:11:11] <skunkworks> https://www.youtube.com/watch?v=ch4TjB4UxDA&feature=plcp
[08:12:07] <r00t4rd3d> how dare you post that here
[08:14:19] <skunkworks> eh - it is my reality tv...
[08:15:03] <r00t4rd3d> watching that dial made me dizzy
[08:16:45] <r00t4rd3d> your buddies come over and drink coffee and watch you play with your machines?
[08:19:04] <r00t4rd3d> alex_joni, the only thing I see that isnt working is the statistics on the bottom of the index
[08:20:41] <r00t4rd3d> not that it is a big deal
[08:21:53] <alex_joni> if you click on more statistics it works
[08:22:04] <alex_joni> I'll look into it r00t4rd3d
[08:22:08] <r00t4rd3d> yeah i noticed that
[08:22:23] <r00t4rd3d> it might take time to update maybe too?
[08:22:57] <r00t4rd3d> i would check if there is a refresh setting or when/how it updates
[08:32:26] <alex_joni> hmm.. linuxcnc.org just crapped out on me
[08:32:36] <r00t4rd3d> n1
[08:32:37] <r00t4rd3d> :D
[08:32:47] <alex_joni> still working for anyone?
[08:32:54] <r00t4rd3d> nope
[08:34:12] <r00t4rd3d> internal server error
[08:37:11] <alex_joni> ok, stop reloading for a bit if possible
[08:37:51] <r00t4rd3d> you updating everything?
[08:38:11] <alex_joni> there was an option which said: enable general statistics
[08:38:22] <alex_joni> set to no, I flipped it, and it started 500'ing
[08:39:13] <r00t4rd3d> overload
[08:40:42] <alex_joni> but it wasn't from me
[08:40:47] <alex_joni> now it works for me
[08:40:58] <alex_joni> showing stats and all
[08:40:59] <r00t4rd3d> me2
[08:41:10] <alex_joni> ok.. I'll leave it at that
[08:41:15] <r00t4rd3d> stats are up too
[08:41:35] <r00t4rd3d> while querying the database to update the stats it probably shut everything down
[08:44:30] <r00t4rd3d> is it normal for 78 people to be online?
[08:45:42] <alex_joni> r00t4rd3d: no, but they requested it ;)
[08:46:00] <alex_joni> it's mostly lost sessions.. the 15min timeout was too small
[08:46:05] <alex_joni> it's set to 24h or so now
[08:46:07] <r00t4rd3d> Total users online: 79 Members and 34111 Guests Online
[08:46:34] <alex_joni> I doubt there are 34k guests online
[08:46:41] <r00t4rd3d> lol
[08:46:59] <r00t4rd3d> they were all just waiting for a forum update :D
[08:47:36] <jdh> 34,109 of them are waiting to spam
[08:48:02] <r00t4rd3d> maybe its not so easy for them to register now
[09:00:23] <jdh> anyone made a raspberry pi case?
[09:02:38] <mk0> someone yes
[09:03:59] <mk0> i saw info at someones nick "raspberry pi user"
[09:04:41] <jdh> I've seen lots of stuff for printing them. I'd like to make a pocketed one
[09:06:25] <alex_joni> there's a lego case for rasps
[09:08:53] <jdh> need something a little more robust than that.
[09:08:56] <r00t4rd3d> finished : http://imgur.com/a/2oCcE
[09:09:15] <jdh> did you mean to misspell that?
[09:10:23] <jdh> I'm going to take friday off and try to make one of those. If my booster doesn't show up.
[09:11:20] <r00t4rd3d> misspell what?
[09:11:37] <jdh> just kidding :)
[09:11:47] <jdh> looks nice.
[09:28:39] <r00t4rd3d> make and example and find a school teacher to bring it in and they will sell like hot cakes
[09:28:48] <r00t4rd3d> make a *
[09:36:32] <JT-Shop> awallin: mind if I ad your pid page to http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Tutorials
[09:45:19] <jdh> I don't want to sell anything
[09:46:09] <jdh> r00t: is the darker part of the letters just from the depths, or burning, or grain or what?
[09:50:31] <r00t4rd3d> stain
[09:50:59] <r00t4rd3d> i use a brush and paint the cuts with gel stain then wipe off the top
[09:53:23] <r00t4rd3d> after the stain dries you can sand it right back down to the wood if you want and it will make the lettering really dark
[10:01:22] <L84Supper> I currently see no evidence of "hotcakes" selling in high volumes :)
[10:01:57] <archivist> I prefer free cakes to buying
[10:02:48] <archivist> said while eating cake from a neighbour
[10:07:51] <L84Supper> http://www.thingiverse.com/tag:Raspberry_Pi
[10:09:19] <L84Supper> better ones here http://venturebeat.com/2012/07/16/9-amazing-raspberry-pi-case-mods-including-one-that-looks-like-a-raspberry/
[10:13:35] <cncbasher> setting a bias offset for zero point for vfd is this correct ... pwmgen.scale 100 pwmgen.value 45.0 and pwmgen offset 50.0
[10:13:48] <cncbasher> is their anything iv'e missed ?
[10:20:43] <jdh> http://www.adafruit.com/products/922
[10:20:58] <elmo40> kinda tiny
[10:21:24] <jdh> yeah, I hear that a lot :(
[10:21:48] <elmo40> lol
[10:42:38] <L84Supper> jdh, those work well, we have been using them for over a year, they are much lower cost by other sellers
[10:45:21] <L84Supper> http://www.youtube.com/watch?v=OJzjrFRwouQ
[10:45:31] <jdh> I was looking for a little Pi monitor and saw those. I don't think I'll need a kb though
[10:49:58] <L84Supper> jdh: mini HDMI monitor or?
[10:50:42] <jdh> http://www.amazon.com/Camera-Monitor-Support-Rotating-Screen/dp/B007SLDF7O
[10:50:51] <jdh> I just ordered one of those. Hopefully sufficient
[10:51:18] <L84Supper> you'll see an image :)
[10:51:40] <jdh> I want to disply 4 numbers. A graph woudl be nice also, but not required.
[10:52:11] <jdh> I was going to use a 4x20 lcd, but figured I'd try graphical first.
[10:53:42] <L84Supper> the selection on Amazon has improved, 3.5" lcd's for $18, 4.3" for $24
[10:54:10] <jdh> yeah, I thought about those. 4.3 might fit better, but was hoping the 7" would be more readable
[10:54:42] <jdh> and just tap for ctrl anyway
[11:52:59] <IchGuckLive> hi all B)
[12:07:08] <awallin> JT-Shop: sure go ahead and link to my page from the wiki. If I do another tuning-session with a new machine at some point maybe I should document that a bit better, could go into the manual..
[12:07:56] <JT-Shop> ok thanks
[12:11:42] <Jymmm> http://www.wimp.com/sleepingdogs/
[12:14:41] <Connor> Do you think it's possible, or has anyone here ever made a spiral tap from a drill bit? Was thinking you cool anneal it, run a die down it.. maybe, or cut the threads on a lathe.. and the re-harden it..
[12:26:47] <Jymmm> JT-Shop: You ever repair/patch a roof?
[12:34:42] <WalterN> Connor: they make grinding wheels to attach to manual lathes for putting in threads in hard things
[12:42:32] <jthornton> Jymmm, many times
[12:44:19] <Jymmm> jthornton: WTh is the difference in all these roofing coatings?! Can't make heads or tails of them. trying to just coat a leaking ashphalt tile roof
[12:44:42] <jthornton> I'm a single man
[12:44:46] <jthornton> shingle
[12:44:52] <Jymmm> jthornton: apx 550 sq ft
[12:45:24] <Jymmm> jthornton: Were not replacing the roof, just gooing it up
[12:46:10] <Jymmm> http://www.gardner-gibson.com/
[12:47:26] <jthornton> I'm a shingle man
[12:47:33] <Jymmm> jthornton: Someone told us about "Henry's Wet Patch" (home depot), but they got sneaky and quoted coverage based on 5gal, even though they sell 3.5gal buckets.
[12:47:45] <Jymmm> jthornton: and you never patch a roof?
[12:47:54] <jthornton> with shingles yes many times
[12:48:22] <Jymmm> and around flashing and roof vents?
[12:48:25] <jthornton> remove bad shingles replace with new ones
[12:48:37] <jthornton> I use the black tar stuff in a tube
[12:48:56] <jthornton> but I hear tell they have a better more expensive version of it now
[12:49:48] <Jymmm> k
[12:57:21] <JT-Shop> do you know where it is leaking at?
[13:04:36] <Jymmm> No, just in about 10 places in one room
[13:12:59] <jthornton> it could be coming from one place and the water can run under the shingles till it hits a hole and then drop
[13:13:16] <jthornton> if you can see in the attic where the water is dripping from it usually points to the leak
[13:41:33] <Jymmm> jthornton: Yeah, no attic/crawlspace, just a flat pitched roof.
[13:46:14] <archivist> flat OR pitched decide which
[13:50:41] <Jymmm> I guess it's called a gable roof
[13:53:49] <archivist> sloped like http://archivist.info/herron/img/CNV00005b.JPG
[13:54:05] <Jymmm> yeah
[13:54:56] <archivist> because flat is a can of worms that needs sealing, gable is a lot easier to fix
[13:56:27] <JT-Shop> Jymmm: is it a rubber flat roof?
[13:57:50] <Jymmm> rolled out asphalt
[14:02:36] <archivist> replace/recover if cracked
[14:04:53] <archivist> isnt the place rented?, scream at the landlord
[14:16:12] <Jymmm> archivist: Have been for the last few years; doing the repair and deduct from rent route.
[14:16:23] <Jymmm> (again)
[14:19:09] <Tom_itx> the ll is good with that?
[14:20:21] <Jymmm> Calif Law
[14:20:46] <Tom_itx> huh
[14:21:15] <Tom_itx> to you get top wages for that?
[14:21:21] <jdh> anybody need some high presssure regulators? I bought too many and they are not so great for my application.
[14:21:42] <Tom_itx> how high?
[14:23:28] <jdh> 0-6000 in and out
[14:23:28] <jdh> I need 145 max out. That's barely on for these regs.
[14:23:28] <Tom_itx> oh for skuba gear?
[14:23:28] <jdh> indirectly
[14:23:31] <jdh> I bought a gas booster that uses 145psi max input for drive gas.
[14:23:32] <Tom_itx> not me
[14:24:31] <jdh> I would repair things for my landlord, if they paid my usual and customary hourly rate for the repair.
[14:24:46] <jdh> but, if they did that, they would be too stupid to rent from.
[14:31:32] <cncbasher> could someone put me rigiht on setting up pwm bias on a 5i20 see http://pastebin.com/s8TxixKN
[14:32:25] <cncbasher> i dont appear to have the offset command correct as it giving me an error
[14:35:27] <PCW> There is no offset AFAIK
[14:36:55] <PCW> if you want 50% = 0 PWM you need to add an offset to the PID value (maybe with the scale comp)
[14:37:28] <PCW> ow PWM value I shouldl say
[15:04:14] <Jymmm> When it come grades of stainless, say 304, is it's temper implied, or is that an additional spec on top?
[15:07:45] <WalterN> does it even matter for 300 series stainless?
[15:08:07] <andypugh> It's an additional spec on top
[15:08:21] <Jymmm> For my application, yes. I've gone through a few grades of SS so far.
[15:08:28] <Jymmm> andypugh: ok, thanks.
[15:08:48] <andypugh> WalterN: Yes, full-hard straight from the cold rolling mill is a lot stronger than anealed.
[15:09:03] <Jymmm> andypugh: so like 304-2b FH ?
[15:09:20] <andypugh> I am not _entirely_ sure how you specifiy the temper.
[15:09:36] <andypugh> (When this mattered to me I had my own little cold rolling mill)
[15:09:52] <Jymmm> andypugh: np, I'll see what I can find out.
[15:13:29] <Tom_itx> http://www.precisionsteel.com/technical-data/tempers/stainless-steel
[15:15:13] <Jymmm> Ok, by that chart I think I need FH
[15:17:19] <Tom_itx> http://www.mastainless.com/tempered
[15:19:35] <tjb1> Hey, is there a way to treat a probe as a limit when not probing? An easy way? jdh suggested using and2
[15:27:30] <andypugh> Jymmm: I seem to recall we calculated you needed 180000psi, but 200,000 wouldn't hurt
[15:28:01] <andypugh> tjb1: Possibly or2, rather than and2
[15:28:32] <tjb1> I think jdh was thinking probe and input high = probe, probe low and input high = limit
[15:39:44] <andypugh> You can probably use the "logic" HAL function to give you both the OR and AND outputs.
[15:41:11] <andypugh> PCW: Do you think that Mesaflash (micges's thing, I think) should be included in the LinuxCNC source?
[15:41:20] <PCW> Yes
[15:41:42] <PCW> but he has the latest source
[15:42:52] <PCW> or maybe in the firmware bundle
[15:43:52] <andypugh> Hmm, yes, maybe it lives in /lib/firmware/hm2/5i25...
[15:44:01] <andypugh> The executable at least.
[15:44:03] <PCW> latest version can flash the 7I80 over Ethernet
[15:44:40] <PCW> and the 6I25 including 6I25 recovery mode
[15:45:25] <PCW> so its more generic than just 5I25
[15:47:20] <PCW> lib/firmware/hm2/tools?
[15:47:44] <andypugh> Possibly. There may be rules though.
[15:48:18] <PCW> I think there are RPO and WPO included with mesaflash there as well
[15:48:35] <andypugh> RPO and WPO?
[15:49:56] <PCW> direct register read and write utilities for hardware debugging
[15:51:10] <PCW> Read with Pci Offset
[15:51:10] <PCW> Write with Pci Offset
[15:51:16] <andypugh> OK. Not directly useful to tonights task then.
[15:51:35] <PCW> RPO 6800
[15:51:37] <PCW> WPO 1204 00AACC33
[15:51:45] <andypugh> Just wanted to check prior to any wheel-reinventing
[15:52:25] <PCW> mesaflash is _interesting_ as the source is Linux and Windows compatible
[15:53:05] <andypugh> That's just showing off, that is.
[15:53:33] <PCW> Micges did a good job
[15:54:45] <PCW> I dont think there are any major side effects to upper level code
[15:55:25] <PCW> just the low level hardware/network access
[16:04:36] <jdh> I was thinking probeflag&&input to probe, ~probeflag&&input to limit
[16:04:55] <jdh> but now I'm thinking about going home.
[16:12:03] <mrsun> hmm unsupported 25mm axle, how long do you think that could be before it flexes to much for routing wood ?
[16:13:04] <tjb1> where at?
[16:13:14] <tjb1> Where the gantry rides or for the z axis?
[16:14:16] <mrsun> say for a X axis of a router
[16:14:22] <mrsun> if the Z axis is in the middle of it
[16:14:35] <mrsun> i have no references to how stiff 25mm axles are =)
[16:15:01] <andypugh> How long is it?
[16:15:02] <mrsun> http://hackedgadgets.com/wp-content/2/Fireball_V90_CNC_Router_Assembly/Fireball_V90_CNC_Router_Assembly_794.JPG like that for example
[16:15:18] <mrsun> andypugh, that is waht im asking, how long would it be able to be not be a problem =)
[16:15:27] <mrsun> (dual axle ofc) but still
[16:15:38] <mrsun> preferablly i would like about 120cm travel
[16:15:45] <mrsun> so it would have to be like 140cm long
[16:17:28] <andypugh> http://www.engineeringcalculator.net/cross_section_properties.html and shoose the circle
[16:18:06] <mrsun> hmm nvm, its almost as cheap to buy the supported rails compared to buying just axles :P
[16:20:01] <andypugh> But http://www.engineeringcalculator.net/beam_calculator.html is really nice
[16:20:18] <mrsun> that first link doesnt work to well in chrome :/
[16:20:37] <andypugh> And you only need the E for steel (200 GPA) and the I for the shape
[16:20:53] <andypugh> I am not sure the first link works at all.
[16:22:22] <DJ9DJ> gn8
[16:34:13] <mrsun> 3700 sek for supported rails + bearing blocks from germany for a 120x120cm router
[16:35:22] <mrsun> ofc ordering from china i would get ballscrews also :P
[17:37:14] <jthornton> anyone here not registered on the forum?
[17:43:16] <andypugh> You need a guinea pig?
[17:44:03] <JT-Shop> yea
[17:45:18] <JT-Shop> andypugh: have you seen any spammers today try and register?
[17:45:23] <andypugh> Hundreds
[17:45:52] <JT-Shop> I must be looking right after you delete them
[17:46:26] <andypugh> Or they were a backlog
[17:46:30] <JT-Shop> well since afternoon your time
[17:46:57] <andypugh> A few, I think.
[17:47:08] <andypugh> I just approved a real person
[17:49:46] <JT-Shop> did he confirm?
[17:53:15] <andypugh> Ah, no.
[17:53:36] <Tom_itx> zlog
[17:54:45] <Tom_itx> i don't think i am
[17:54:55] <andypugh> There is at least one new guy not in the Unconfirmed list.
[17:55:40] <JT-Shop> wow 11 unconfirmed
[17:56:34] <andypugh> Some have been there weeks
[17:56:54] <andypugh> (I re-sent confirmations already)
[18:01:28] <JT-Shop> lol so did I
[18:02:44] <andypugh> I sometimes email direct too. We can manually confirm them.
[18:04:39] <JT-Shop> looks like Sterling is making progress using 8.04
[18:08:10] <Jymmm> andypugh: Yeah, I just didn't associate the 180000 to "Full Hard"
[18:27:08] <JT-Shop> Jymmm: you ever register on the forum?
[18:30:40] <andypugh> He did
[18:34:27] <JT-Shop> must be working ok I just saw a chap from down under register and confirm
[18:40:52] <r00t4rd3d> do router bits like this do well in cnc machines?
[18:40:53] <r00t4rd3d> http://www.precisionbits.com/images/thumbnails/0/800/600/14152.jpg
[18:40:59] <r00t4rd3d> for cutting wood?
[18:41:00] <JT-Shop> crap, I need to expand my shop
[18:41:20] <jdh> build a new shop!
[18:41:45] <PCW> already?
[18:41:51] <Tom_itx> already!?
