[04:57:20] <jtektool> any nfo admins on here
[05:02:41] <factor> You are correct
[05:02:49] <factor> not an admin , but its down
[05:04:22] <jtektool> thanks for the nfo was having a heart attack
[05:05:10] <jtektool> thought my router was melting or something had to open it up yesterday and put a heatsink on the wireless chip
[05:05:44] <jtektool> been a long time since i used a text irc client
[05:06:00] <jtektool> lol
[05:15:09] <jtektool> anyways anybody in here got experience cutting G10 with a carbide insert (30 degree) im taking .050 off at a time using my vertical mill as a lathe and putting the part in a mandrel
[05:16:02] <jtektool> using X axis to bring the insert in toward the part
[05:19:06] <jtektool> just wondering what would be best for tool wear as per speed/feed
[05:19:26] <jtektool> I have little experience using lathes but this is very much like a lathe setup
[05:21:00] <jtektool> parts coming out alright did about fifty before i seen any wear on the gold coating

[11:45:36] -!- Calyp has quit [Quit: Leaving]
[11:45:54] <automata> Is there a way to set the current machine coordinates to 0,0,0 from MANUAL mode? This is without using G92X0,Y0,Z0 in MDI mode

[11:53:10] <jthornton> G92 sets a coordinate system offset not the machine coordiantes
[12:02:05] <automata> Just trying Homing...
[12:16:35] <jthornton> why do you want to change the machine coordinates?
[12:28:22] <automata> I am developing a new GUI
[12:28:51] <automata> I want to provide a zero out button...
[12:30:14] <automata> On pressing that button, the machine coordinates will be zeroed out.. and further any further commands will refer to the zeroed out point as the actual zero...
[12:31:32] <automata> This seems to be exactly the operation of G92X0Y0 command...
[12:46:07] <JT-Shop> you might want to read the manual on G92...

[13:14:42] <archivist> SWPadnos, I know what its like :) I had a mains failure here yesterday, and the server refused to return to life, took me a while and about 40 screws to get the hd out and then port into this box
[13:15:04] <SWPadnos> no, this is hacking. the server is up, but linuxcnc is disabled
[13:15:17] <SWPadnos> (so the site is down :) )
[13:16:18] <archivist> well similar recovery, rebuild server
[13:16:55] <SWPadnos> nah. update old CMS that has known exploits, hope nothing breaks, and hope it's another few years before the new version gets hacked
[13:17:35] <archivist> been doing some sql injection fixing stuff on a friends server after he got hacked
[13:19:22] <archivist> then they send a blackmail email..we got in and £99 pounds to tell you how

[14:48:50] <Jymmm> I'm trying to replicate a cutting table insert for my laser, but having the darnest type figuring out where to begin. I was thinking of using aluminum extrusion, but can't find the "perfect" profile, maybe use MDF as well. The cutting table sits in the machine, and is aligned to existing rulers on the bed.
[14:49:03] <Jymmm> Disassemebled: http://i53.tinypic.com/n63oyb.jpg

[14:50:39] <pcw_home> Damn, need a coat on to go outside in the middle of August
[14:53:37] <John_f_> Jymm: maybe the right kind of radiator core would work
[14:54:13] <Jymmm> John_f_: I already have the honeycomb, it's the frame/box I need to replicate
[14:55:18] <Jymmm> HC (honeycomb) is replaced when too yucky.
[15:13:31] <Jymmm> I can't tell if it's this (front cut away) profile: http://i53.tinypic.com/xmu33n.jpg or this one http://i52.tinypic.com/2nqz9uh.jpg I'm thinking it's welded on.
[15:17:47] <JT-Shop> well it is angle around the outside that the ruler bolts to
[15:18:31] <JT-Shop> baffles and inner ledge might be one box inside of the outer box
[15:18:34] <Jymmm> Right, and THAT ruler has to align to the ruler on the table bed (not pictured)
[15:19:13] <JT-Shop> take a picture of the table bed
[15:19:26] <Jymmm> http://www.expatriates.com/img/13648424.4.jpg
[15:20:12] <JT-Shop> do you have one a bit bigger?
[15:22:07] <Jymmm> JT-Shop: Just think a big flat area with a framers square bolted to it
[15:23:53] <Jymmm> the cutting table insert (shown above) aligns to the existing rulers
[15:24:18] <Jymmm> kinda like this http://1.bp.blogspot.com/-9YXtrsQ2jYA/TcAoYpymH6I/AAAAAAAABlI/D9D2dIFPNIE/s1600/laser+cutting.jpg

[15:27:07] <JT-Shop> so just make a box and put angle on the outside for the rulers and angle on the inside for the HC
[15:27:11] <Jymmm> JT-Shop: Here you go... http://4.bp.blogspot.com/_NWbva_rHdVc/R1RgIRcsd7I/AAAAAAAAAUc/t6Abxh0SZoo/s1600-R/P1010412.JPG
[15:27:24] <Jymmm> see the black rulers on the top and left side?
[15:27:41] <Jymmm> JT-Shop: Make a box out of what?
[15:27:42] <JT-Shop> yea
[15:27:48] <JT-Shop> sheetmetal
[15:28:15] <Jymmm> JT-Shop: The area below the HC can NOT be flush with the bottom of it, there needs to be airflow.
[15:28:31] <Jymmm> I dont have any sheet metal tools
[15:28:37] <JT-Shop> 10:28 JT-Shop so just make a box and put angle on the outside for the rulers and angle on the inside for the HC
[15:28:43] <JT-Shop> rent them
[15:29:11] <JT-Shop> you live in the big city? surly you can find a sheet metal brake for rent
[15:29:27] <JT-Shop> surely
[15:29:33] <Jymmm> Uh, no. And I don't hae the knowledge to use them anyway.
[15:29:38] <JT-Shop> dang e key must be stuck
[15:29:47] <JT-Shop> rent the knowledge too
[15:31:10] <Jymmm> It doesn't have to be sheet metal, that's just what they did.
[15:32:19] <JT-Shop> make from MDF then or pressboard or...
[15:32:28] <JT-Shop> luan
[15:33:17] <Jymmm> Yes, then I still have to align the edge of the box with the base ruler, and build an outside ledge for the top ruler, the profiles dont match
[15:33:32] <JT-Shop> seems pretty dead simple to replicate with all those fine photos you have of the actual part
[15:34:04] <JT-Shop> they don't match on the one you showed me either
[15:34:21] <Jymmm> JT-Shop: They do actually.
[15:35:27] <JT-Shop> not the way you describe it they don't match the base is the ruler width inset
[15:36:13] <Jymmm> Where the top ruler is mounted aligns with the bottom one.
[15:37:34] <JT-Shop> I don't see the problem
[15:39:04] <JT-Shop> is the top ruler and the bottom ruler the same width?
[15:39:50] <Jymmm> JT-Shop: That doens't matter, what does matter is that both rulers alignment are the same on the right edge.
[15:41:04] <JT-Shop> so make it that way
[15:43:01] <Jymmm> http://i51.tinypic.com/30vi4if.jpg
[15:44:05] <Jymmm> the HC has to recess under the rulers by about 1/2"
[15:44:22] <Jymmm> s/rulers/top ruler/
[15:45:56] <Jymmm> The right edges of both rulers have to align.
[15:46:31] <JT-Shop> I still don't see what the problem is put a spacer if needed on the bottom to make them align

[15:47:14] <JT-Shop> you say the left edge don't matter just the right edge so just position the top ruler right edge so it lines up with the bottom ruler right edge
[15:47:45] <Jymmm> JT-Shop: If I do that XY ==00 will now be XY {width_of_spacer}
[15:48:23] <Jymmm> JT-Shop: Yes, but the HC has to overlap
[15:48:24] <JT-Shop> I guess you can't have everything unless you make/buy a proper one
[15:48:38] <Jymmm> JT-Shop: At $1200, I don't think so.
[15:51:47] <skunkworks_> I cannot believe that I still sometimes forget to home the k&t and run it into the over travel switches.
[15:52:09] <skunkworks_> (jogging)
[15:52:21] <JT-Shop> must have no force homing on?
[15:53:46] <skunkworks_> I do - but I can still jog it.
[15:54:23] <skunkworks_> (jog wheel) I think that is a feature by design
[15:54:56] * skunkworks_ hugs his touch probe again
[15:55:14] <Jymmm> that's what she said
[15:56:13] <JT-Shop> put a lockout in your hal file for the jog wheel if not homed

[16:10:00] <Jymmm> hahaha, Jooz b33n h@x0r3d!!!
[16:10:28] <jtektool> why would some lame ass hack an open source web site
[16:10:32] <skunkworks_> it is not a big deal - - I cannot hurt the machine.. I just wakes you up when everything shuts down from hitting the over travel limits.
[16:10:49] <Jymmm> jtektool: It was a bot that hacked joomla
[16:11:00] <JT-Shop> darn the video of you testing it would have been funny

[16:12:35] <Jymmm> so it won't happen again?
[16:13:10] <Jymmm> Also, did anyone wlk through the database to look for hidden injected credentials?
[16:13:22] <jtektool> wasnt even aware of joomla im using phpBB
[16:13:28] <jtektool> on my servers
[16:13:41] <Jymmm> phpBB is even WORSE for security
[16:13:58] <Loetmichel> *grrr* such a normal tap is just tooo small for filling a little pool... first m^3 in, 5 to go.....

[16:14:24] <jtektool> but why not add a ssl layer
[16:15:07] <Jymmm> jtektool: That doesn't stop bot from exploiting joomla or phpBB or any other application.
[16:16:14] <Jymmm> Usually it's a sql injection exploit, not a "I found someone's password" exploit
[16:16:36] <jtektool> so its a mysql problem not a buffer overflow

[16:25:24] <jtektool> so is it a known bug in mysql...just wondering cuz i got three servers using mysql databases with phpBB
[16:26:11] <Jymmm> jtektool: No, it's not specifically MySQL, it could be PG, or MS-SQL, or SQLite.
[16:26:54] <Jymmm> it's a php code exploit injecting sql commands where they should be able to do so.
[16:27:12] <Jymmm> s/should/should not/
[16:28:10] <jtektool> because of the way php escapes charcters?

[16:30:10] <jtektool> moreover how to prevent it if i can
[16:30:41] <Jymmm> jtektool: the link I gave has the information you seek.

[16:41:48] <jtektool> sorry i do have a topic here just go off on tangents
[16:41:57] <JT-Shop> anyone have plans for a Ballista using a leaf spring
[16:42:17] <jtektool> where is the best place to put a ss relay in circuit
[16:43:28] <jtektool> in between the capacitor and the drives?
[16:44:02] <pcw_home> No unless you like fires
[16:44:08] <Jymmm> JT-Shop: I was thinking of using 2x1" aluminum angle riveted together to form the offset Z profile, then miter cut the corners at 45 degree. Then use MDF for the bottom and drill/countersink the aluminum frame so I can screw it to the MDF to give it some weight and help keep it square
[16:44:43] <Jymmm> JT-Shop: I can use the MDF to screw the supports too as well.
[16:45:57] <jtektool> how about a real answer like where I have it between the transformer and the capacitor which seems to work but therez still a helluva a charge on the cap
[16:46:06] -!- skunkworks_ has quit [Remote host closed the connection]
[16:46:47] <Jymmm> bleed resistor
[16:47:07] <jtektool> therez also a discharge resistor to ground and a resistor between the terminals on cap

[16:47:31] <skunkworks_> http://www.youtube.com/watch?v=jtGkUwVr9ZA
[16:47:33] <pcw_home> thats where it belongs bu use a NC contact on a real relay to do a fast discharge (say 1 second)
[16:48:20] <pcw_home> This also brakes your drives (assuming they are servo)
[16:48:49] <Jymmm> DPDT relay seems a lot better than a SSR
[16:49:13] <jtektool> there was a ssr originally in the machine
[16:49:49] <jtektool> didnt even know they had them back in 1989 lol
[16:50:13] <pcw_home> Yep NO or SSR in series with AC side, NC relay on charge dump or DPDT for both
[16:50:26] <JT-Shop> Jymmm: can you find 2 x 1 x 1/8 6061 angle?
[16:50:56] <Jymmm> JT-Shop: I'm 90% sure I can today. 100% sure during the week.
[16:51:20] <jtektool> i have ssr in series on ac side before rectifier
[16:51:30] <pcw_home> SSRs are normally AC only (wont turn of with DC)
[16:51:42] <pcw_home> s/of/off/
[16:52:04] <jtektool> well control signal is dc
[16:52:08] <jtektool> 5v
[16:52:36] <pcw_home> Right but they normally only switch AC
[16:53:25] <jtektool> it definately shuts off ac power but i had a condition where i had the encoder wired backwards and the drive kept going after estop
[16:53:54] <pcw_home> So safest thin is a fast charge dump/brake with power off/estop
[16:54:01] <pcw_home> thing
[16:54:32] <Tom_itx> JT-Shop, use vw front torsion bars
[16:55:14] <JT-Shop> two twisty the little greasy flat buggers
[16:55:18] <jtektool> luckily i wired a stop button which stops the drives as they just take a 5v stop signal to (ground)
[16:55:27] <JT-Shop> Tom_itx: I have the spring
[16:55:44] <Tom_itx> wtf are you making now?
[16:55:54] <pcw_home> Also drives should be disabled by Estop as should servo primary power, the the next step is to dump the charge when servo primary is off
[16:56:41] <Tom_itx> q. should the power supply to the step drivers be brought up after the logic supply and shut off before it or will it matter that much?
[16:57:11] <Tom_itx> and if so, what's a good way to do that
[16:57:32] <pcw_home> This is especially important for DC servos where a drive power component failure can result in a runaway
[16:57:39] <JT-Shop> Jymmm: like this http://imagebin.org/168873
[16:59:29] <JT-Shop> Tom_itx: this http://imagebin.org/168874
[17:00:11] <Tom_itx> huntin grey squirrels?
[17:00:23] <skunkworks_> our amc drives have their own power supply. We cut the power during estop - but I don't know if they brake or not. has not been an issue yet -
[17:00:52] <Tom_itx> JT-Shop, that looks like a wicked weapon
[17:02:19] <Jymmm> JT-Shop: The only issue I see with that is the ledge on the right side (that the honeycomb sits on) blocks airflow below it.

[17:04:11] <Jymmm> Tom_itx: tell me about it.
[17:04:19] <JT-Shop> then you can't use 1x2 angle and have the ruler hang over the HC by 1/2"
[17:04:21] <archivist> worries too much
[17:04:48] <Jymmm> JT-Shop: That's what it's doing here... http://i51.tinypic.com/30vi4if.jpg
[17:05:18] <skunkworks_> over-engineers? ;)
[17:05:28] <Tom_itx> why do you need 2 rulers?
[17:05:29] * skunkworks_ is a kobler
[17:05:32] <Jymmm> JT-Shop: The lil sqare the the left of the HC is 1/2" square bar.

[17:05:46] <archivist> just mekkit work TM
[17:06:33] <Jymmm> Tom_itx: The top ruler is attached to the cutting insert, which is aligned to the bottom (fixed) ruler, so that they are both at the same registration points.

[17:15:10] <JT-Shop> you said you need 1/2 of HC under the ruler
[17:15:25] <Jymmm> JT-Shop: The working area of the table is 12x24", the HC can go outside this area. But the HC HAS to have airflow under it at the 0,0 points, I can't have a 1/2" area around the edges of the HC with no airflow below it.

[17:16:46] <Jymmm> JT-Shop: No, see the drawing I keep showing, the HC goes outside the area by 1/2"
[17:17:09] <Jymmm> -0.5"
[17:17:10] <JT-Shop> that's what I'm showing exactly
[17:17:15] <Tom_itx> suspend it from the corners with door springs
[17:17:28] <JT-Shop> the HC is 1/2" under the right side of the ruler
[17:17:48] <Jymmm> JT-Shop: Ok, on the last drawing you linked me too, where does it sit flush with the bottom ruler?

[22:01:55] <JT-Shop> ouch
[22:02:31] * JT-Shop goes to discuss Ballista construction with the neighbor
[22:03:02] <andypugh> Trebuchets are rather more elegant.
[22:09:20] <Jymmm> Tom_itx: Nah, they can grab it from SoCal, just one stick minimum purchase
[22:09:48] <Jymmm> Tom_itx: $75
[22:10:04] <Jymmm> 3-5 days to arrive

[22:41:07] <KimK> andypugh: Yes, I'm working on it right now. I have another (different) PC available now and I've been doing some swapping, it looks promising. Right now I'm copying the hard drive so I don't have to swap the sole HDD. More in a while.
[23:19:36] <Tom_itx> KimK, you still in town working?
[23:19:44] <frysteev> any servo savvy people online atm?
[23:20:35] <andypugh> How savvy do you need?
[23:20:57] <frysteev> my servos have brakes on them, im curious how the brakes are typically controlled
[23:21:54] <andypugh> In CNC you normally wouldn't. Perhaps in a 2.5D situation with a heavy knee
[23:22:12] <frysteev> its in a robotic arm,
[23:23:07] <frysteev> im tracing down an error, one of causes maybe a faulty brake, cuasing an overcurrent on the motor controller
[23:23:41] <andypugh> You might find the discussion here useful: http://thread.gmane.org/gmane.linux.distributions.emc.user/26042/focus=26105
[23:23:53] <frysteev> and google has been fail, any search combination with brake and servo brings up only sutomotive stuff
[23:25:54] <andypugh> You could consider using a HAL wcomp component on axis velocity to engage the brake. Possibly with a debounce component so that it only engages the brake after 1s of no-move
[23:28:26] <andypugh> Try this as your google search term
[23:28:27] <andypugh> "servo motor" brake -"brake servo" -vacuum -car -automotive
[23:28:55] <frysteev> im still figuring it out, havent even gotten to connecting to emc yet

[23:33:05] <andypugh> I think brakes typically use current to release.
