[03:01:32] <eli7777> i was trying to set up a zenbot router and the paper work that make with it doesnt seem to give enough info to set up the driver type, step time and step space. could some one help with this. i tried looking it up in the forms but its only pulling up a page that says access denied
[03:03:41] <elmo40> eli7777: one of these? http://www.zenbotcnc.com/
[03:05:08] <elmo40> their xml file gives plenty of info.

[11:39:52] <jthornton> you might be able to set the parameters but I'm not sure if that is stored in the var file or not
[11:40:35] <cradek> no, that is set by homing only

[15:45:13] <skunkworks> we just canned a bunch of tomatoes again. working well
[15:45:51] <JT-Shop> cool, I nuked my garden this year to kill off the grass
[15:47:29] <syyl> for a green shine?
[15:49:02] <skunkworks> the tomato plants look sad.. but the peppers are going gang busters.
[15:49:27] <skunkworks> thought they where done - but now they all have a bunch of baby peppers on them

[16:15:09] <Loetmichel> re @ home
[16:16:09] <pcw_home> We didn't do a garden here this year. Sorta OK since August has been colder than February
[16:17:36] <pcw_home> tomatos would have been in suspended animation...
[16:17:45] <skunkworks> we have had prolonged hot weather this summer - seems to have really helped the peppers
[16:18:38] <pcw_home> Yeah those tropical things like heat if they have enough water
[16:19:34] <skunkworks> right
[16:19:51] <JT-Shop> I'm planting a food plot for the deer for this winter
[16:20:10] <skunkworks> we have 4 55 gallon rain barrels that have really helped
[16:20:13] <JT-Shop> the grass had such a good root system that it would overtake the tomato plants
[16:20:35] <JT-Shop> Eraser took care of the grass :)
[16:21:00] <pcw_home> We did raise an unintentional clutch of chickens, One of our hens dissapeared in June, we thought the worse but she came back middle of July with 16 chicks in tow
[16:21:15] <skunkworks> heh - funny
[16:21:35] <pcw_home> Now we have to deal with the unwanted roosters
[16:22:38] <skunkworks> our little village passed and ordinance that allows for 5 chickens - no roosters.
[16:22:39] <pcw_home> We have food and water for deer , at least thats what they think
[16:23:20] <JT-Shop> coq au vin for the roosters
[16:23:28] <skunkworks> although you are not supposed to butcher them....
[16:23:33] <skunkworks> heh
[16:23:33] <pcw_home> Invariably the little ones the get trapped in our fence and I have to chase them out
[16:23:49] <pcw_home> (little deer)
[16:24:05] <JT-Shop> I bet that can be exciting at times
[16:25:15] <pcw_home> More exciting than I like but its bad for them here because sheep carry diseases deer shoudln't get and vice versa

[17:25:03] <skunkworks> This is interesting... is he trying to use emc to dampen a pendulum? http://www.youtube.com/watch?v=QlRLrLOaogw
[17:25:23] -!- micges has quit [Ping timeout: 264 seconds]
[17:27:52] <pcw_home> Ive seen some smart controllers that can move the end of the pendulum (or load on crane) to as stop without over or undershoot
[17:28:51] <pcw_home> Convolutional something-aflanget
[17:29:01] <skunkworks> bless you ;)
[17:30:30] <skunkworks> did you see http://www.youtube.com/watch?v=jtGkUwVr9ZA
[17:30:38] <skunkworks> machine is running really quite well
[17:30:47] * skunkworks knocks on wood
[17:32:14] <skunkworks> pcw_home: I saw references to probe input. I assume that isn't working in emc yet?
[17:33:32] <pcw_home> No not yet, I think Jepler worked on it a couple of years ago but didn't get it working
[17:33:42] <skunkworks> ah - I remember that.
[17:34:23] <skunkworks> It would be nice to probe at speed. But really - it works quite well. I use it a lot.
[17:35:04] <skunkworks> slap someting on the table - probe a few points. know exactly where it is.
[17:35:48] <pcw_home> The hardwares there (latch all axis encoder count on probe edge) but i suspect something is not right in duplicating the software probe logic in the driver
[17:37:05] <skunkworks> I remember jeff having issues where it was just not acting as expected.
[17:37:40] <pcw_home> It turns out that for fancy probes its even trickier since they have a fixed (2 mS?) delay from detection to reporting
[17:37:43] <pcw_home> so to do this right requires a history FIFO
[17:37:54] <skunkworks> ewww
[17:38:40] <skunkworks> I pulled all the electronics out of the probe we bought because I didn't have the reciever. It is hooked directly into a fast opto22 module
[17:39:00] <skunkworks> so far so good
[17:39:03] <pcw_home> Was it optical?
[17:39:15] <skunkworks> some sort of inductive thing
[17:41:01] <pcw_home> Oh. I think the newer Renishaw probes are really accelerometers mounted on the probe with a DSP decideing it the probe has been hit
[17:41:19] <skunkworks> scary
[17:41:22] <pcw_home> hence the fixed decision time delay
[17:41:55] <skunkworks> this feels like a normal kinematic device (6 balls - 3 pins)
[17:43:45] <skunkworks> (some sort of renishaw knock off I think) http://www.youtube.com/watch?v=KOi51ogqels&NR=1
[17:44:11] <pcw_home> Yeah I dont know what the advantage of the accelerometer based devices is maybe harder non-metallic balls/rods

[17:59:06] <cradek> tuxcnc is a different project and none of the linuxcnc/emc folks have any control over it.
[18:00:58] <Tom_itx> but you're welcome to switch to emc

[18:02:08] <IchGuckLive> is there a tux outline example anywhere or do i need to generate this over gimp-incscape-pycam

[18:30:58] <skunkworks> The K&T isn't that 'coolant' friendly.
[18:31:54] <JT-Shop> I use air on the BP knee mill for steel

[18:32:29] <JT-Shop> with carbide inserts and carbide end mills
[18:33:21] <JT-Shop> uneven liquid coolant applied to hot carbide will crack it
[18:33:29] <JT-Shop> will/can
[18:34:03] <ds3> JT-Shop: doesn't that assume you will be running the carbide really hot?

[18:35:58] <ds3> really? I have had luck with brushed on coolant (oil) on the brazed carbide w/o any problems
[18:36:36] <ds3> it was a manual machine and definitely wasn't pushed; did it long enough to show that I used the wrong grade of carbide for alum. (pitting)
[18:37:23] <JT-Shop> HSS is better for aluminum in a manual machine sharpened dead sharp
[18:37:46] <JT-Shop> hard to get brazed carbide sharp enough for aluminum
[18:38:19] <Connor> My 1/2" HSS looked to do a good job on Aluminum when I was working with it.

[20:29:35] <Danimal_garage> yea, drives me nuts
[20:29:55] <archivist> Ive been out fiddling nasty routers too today
[20:30:19] <Danimal_garage> first i was having problems with my homegroup, then i was having problems with the wireless, then the wired connection crapped out, and i figured out that the router was bad
[20:30:21] <JT-Shop> one more section of air pipe to hang up and all that is left is put drops where and when I need them
[20:30:31] <Danimal_garage> nice!
[20:31:56] <Danimal_garage> plus the router was pretty old, it wasn't IPv6 ready
[20:32:29] <JT-Shop> what is IPv6?

[20:33:08] <Danimal_garage> they ran out of ip addresses so they're coming out with new ones with more digits, however old routers will be obsolete apparently

[21:41:47] <MOGLI> hello JT-SHOP are you online?? i would like know more about thc control developed by you...
[21:42:51] <JT-Shop> yes for a bit
[21:43:09] <JT-Shop> it's rather simple or I would not have been able to do it :)
[21:43:13] <MOGLI> actually what i would like to know is.. i read about Anti Dive , tip saver features from other vendors, can we implement same in EMC using Other sensors.. if yes which sensors do we neeed
[21:43:28] <MOGLI> or its just a marketing hype
[21:43:58] <JT-Shop> anti dive is the same as corner lock which I called velocity limits I think that is what I called it
[21:44:04] <MOGLI> any good and cheap height sensor for OXYFUEL in your knowledge??
[21:44:20] <JT-Shop> anyway if your velocity is lower than the limit no correction happens
[21:44:36] <MOGLI> so it is already implemented by you .. right??
[21:44:41] <JT-Shop> good and cheap don't seem to go together
[21:44:44] <JT-Shop> yes
[21:44:58] <MOGLI> and what about Tip Saver??
[21:45:11] <JT-Shop> what is it?
[21:45:22] <MOGLI> yes they go together for example EMC.. FREE and Extremly good.... MESA Cheap and BEST ;)
[21:45:56] <JT-Shop> Mesa is what we call cost effective and best support
[21:45:57] <MOGLI> i dont know what it do? something to do with accident.. as far as i can guess..
[21:46:08] <MOGLI> but i read it on candcnc.comi think..
[21:46:55] <JT-Shop> if you have a floating head then no worries and you can use the tip to touch off with a micro switch on the floating head
[21:47:48] <MOGLI> you mean initial height sensing ??
[21:49:22] <MOGLI> and what about THC on OXYFUEL systems?? do you use any???
[21:51:18] <JT-Shop> yes for initial height setting and if the tip touches all stops as the probe input is tripped when not called for
[21:51:34] <JT-Shop> I don't do OxyFuel at this time
[21:52:31] <MOGLI> do i need anything else other than THCAD ??
[21:53:14] <MOGLI> i am planning to use it with 5I20 or 7I43..
[21:53:40] <elmo401> this should work for plasma cutter, no? keep the tip at optimal distance?
[21:55:14] <andypugh> Except, with a plasma you detect arc voltage to set the height. There is no arc voltage with oxyfuel.
[21:55:16] <JT-Shop> for OxyFuel or plasma?
[21:55:37] <JT-Shop> elmo401: that is what I use on my plasma table
[21:58:58] <MOGLI> Plasma
[21:59:20] <MOGLI> any idea for THC on Oxyfuel??

[22:18:22] <Danimal_garage> ha, nice
[22:18:45] <Tom_itx> i saw one at the surplus laying in the mud
[22:18:51] <Tom_itx> made me very sad
[22:18:51] <JT-Shop> I got 4 rails and 8 bearings for cheap
[22:18:59] <Danimal_garage> nice
[22:19:10] <JT-Shop> guy ordered the wrong ones and could not send them back
[22:19:16] <JT-Shop> like scrap price
[22:19:24] <Danimal_garage> i'm thinking 2 rails, 2 bearings per rail
[22:19:33] <Danimal_garage> not sure what size rails i should go with
[22:19:36] <A2Sheds> opendns still blocks linuxcnc.org
[22:20:23] <Danimal_garage> mainly i just need to get rid of the slop
[22:20:28] <JT-Shop> I go by weight or force and double it
[22:20:30] <Danimal_garage> not too much load involved
[22:20:46] <JT-Shop> one extra wide rail may do it for you
[22:21:06] <JT-Shop> just depends on how you can mount them
[22:21:19] <Danimal_garage> the problem is the motor is on a bracket that hangs it off the bearing by like 7 inches
[22:21:27] <Danimal_garage> so any slop is magnified
[22:21:38] <JT-Shop> ouch... lots of overhang
[22:21:54] <JT-Shop> by motor you mean the spindle?
[22:21:55] <Danimal_garage> yea
[22:21:57] <Danimal_garage> yes
[22:23:00] <Danimal_garage> i can lower the actuator to reduce that overhang, but then that reduces workpiece clearance
[22:24:04] <Danimal_garage> so i was thinking, 2 rails, and 4 bearings... keep the bearings far enough apart to reduce the deflection
[22:25:47] <JT-Shop> good thinking

[22:31:18] <JT-Shop> that can be nice when small like that not as much politicking going on
[22:31:28] <andypugh> That was Mechtric, before Omitec bought them out, and moved the company (but none of the staff) 200 miles away. I am not sure they have actually made anything since.

[22:45:26] <Danimal_garage> size is what i was asking about, i think they're 15mm rails
[22:45:30] <JT-Shop> three bearings per rail for some odd reason
[22:45:38] <Danimal_garage> i can take one off
[22:46:01] <Danimal_garage> length is a bit long, but i can cut them

[22:47:38] <Danimal_garage> a bit overkill i think, but i guess that won't hurt and the price is right
[22:48:06] <Danimal_garage> i'll just cut them to about 12"
[22:49:13] <andypugh> Do you think that they might actually be 580mm long?

[23:19:44] <andypugh> I was thinking of three dowels that fitted the slots nicely, which gives good location, then tapered keepers that engage slots in the dowels, pulled up by screws.

[23:20:28] <FinboySlick> That match the table.
[23:20:34] <andypugh> It's not that hard, you need an adaptor plate thick enough to make 4 slots to allow a spanner to get to some nuts.
[23:20:50] <FinboySlick> Pushing dual 't-nuts' in the slots would tighten it in place.

[23:28:49] <Danimal_garage> probably get them at the end of the week or early next week
[23:29:11] <JT-Shop> I should be making Ballista parts
[23:29:13] <Danimal_garage> should be pretty easy to fashion up the mounts and everything
[23:29:34] <Danimal_garage> i should be repopulating my order list so i can make parts
[23:29:46] <Danimal_garage> kinda took last week off :)
[23:30:01] <andypugh> I should be sleeping, but instead I am waiting for Inventor to load in a VM...
[23:30:25] <JT-Shop> yuck I hate waiting for that
[23:30:41] <JT-Shop> Dan you slacker :P
[23:31:09] <andypugh> It's so slow I have to use ctrl-alt-del to see if it has appeared in the processes after I click the icon
[23:33:03] <Danimal_garage> at least i figured out what was wrong with my old garage computer today, so now i have a spare

[23:33:35] <Danimal_garage> the power connector for the hdd was flakey so it was shutting off
[23:33:53] <Danimal_garage> if you wiggled it, the hdd would turn on and off
[23:34:31] <Danimal_garage> changed the connector it was plugged in to and it booted right up
[23:34:54] <Danimal_garage> which is good because it had a ton of files i needed on it
[23:34:55] <andypugh> Ah, yes, Danimal_garage About the Imperial Metric thing, I spent this evening making some 3/8 UNC x M6 brass threaded inserts for a friend. He had an M6 hole stripped out, re-threaded to a not-very-good M8, and 3/8UNC was the next useful step up :-)
[23:35:23] <Danimal_garage> why not an m10?
[23:35:47] <andypugh> It was a bit too much too big.
[23:35:56] <Danimal_garage> i use metric up to about 19mm and thats it, mostly because of wrench sizes
[23:36:38] <Danimal_garage> it's like another language, i may know what the numbers mean, but i always think in inches
[23:37:51] <Danimal_garage> oh well, back to work for me
[23:38:15] <Tom_itx> on the parport mesa cards do most ppl use vusb to power them, pull 5v from the pc supply or just what?
[23:41:19] <JT-Shop> why not M9
[23:41:50] <JT-Shop> I find tap drills for metric taps a snap to do in your head
[23:42:43] <Tom_itx> how so?
[23:43:02] <Tom_itx> M9 is 7.8
[23:44:08] <JT-Shop> drill sizes for metric taps?
[23:44:23] <JT-Shop> subtract pitch from diameter for drill size
[23:44:44] <JT-Shop> M8 1.25 needs a 6.75mm drill
[23:44:58] <JT-Shop> M6 x 1 is a 5mm drill
[23:45:02] <JT-Shop> easy peasy
[23:45:19] -!- Connor has quit [Read error: Connection reset by peer]
[23:45:41] <JT-Shop> so if your making a M25 x 1 you need a 24mm hole
