[00:01:04] <frysteev> so 10000 and 15000 are much better then.

[00:07:45] <Valen> pcw_ hrm?
[00:08:16] <skunkworks> the 2 errors match?
[00:08:49] <PCW_> Yes
[00:09:17] <tjb1> Pcw, only about a week before I am going to drive you crazy
[00:09:28] <PCW_> I'm running a torque loop with the 8I20 driving a 2.2KW motor
[00:09:38] <PCW_> time to go on vacation!
[00:10:25] <frysteev> do you guys rub UPS's on your cnc pc's?
[00:10:42] <PCW_> at 6KHz and 600 IPM is ~1.6 mill difference
[00:10:54] <tjb1> rub?
[00:11:01] <PCW_> at 1 KHz it would be 10 mills!

[00:12:28] <PCW_> and mhaberles patch is harmless as it does not change the default behaviour

[00:14:54] <frysteev> im wondering how you guys handle brownouts in your shops while a job is running
[00:15:34] <tjb1> toilet paper
[00:15:51] <frysteev> lol
[00:16:46] <t12> what does everyone consider proper shop cleaning rules
[00:17:46] <Valen> We have run a UPS on the mill computer but "eh"
[00:18:00] <Valen> we don't get brownouts as a rule, its a blackout or nothing lol
[00:19:37] <frysteev> im planning on putting a UPS on computer, but im wondering about putting the 24 supply on the ups too, so i wouldnt lose encoder position and such,
[00:19:46] <kwallace> The machine should at least trip e-stop if the power goes wonky.
[00:20:55] <Valen> what sort of brownouts are you experiencing frysteev?
[00:20:59] <kwallace> If you have home sensors, it's easy to get your positions back.
[00:21:23] <frysteev> we get random power outages from the city,
[00:21:38] <Valen> black or brownouts?
[00:21:44] <frysteev> the is lots of large condos and such and they are are always doing work on the system around here
[00:21:57] <frysteev> mostly 30 second blackouts
[00:22:12] <Valen> I wouldn't worry about it too much then
[00:22:28] <Valen> if you loose main power your job is basically hosed so start over
[00:22:44] <Valen> use home switches/index or something
[00:23:15] <Valen> worst thing would be for it to think it was running for those 30 seconds, then when main power came back try to keep running
[00:23:34] <tjtr33> 3 relays with series contacts connected to the estop chain, each with a coil across 1 leg of your 3 phase ( drie phase uberwachung ) any drop on any phase gets estop-ed
[00:25:24] <Valen> 3 phase well laaadedah mr fancy pants, when i was a boy we had half a phase and we were LUCKY!

[00:29:21] <AR__> how do i find timing belt to match this gear?
[00:29:29] <AR__> and a matching smaller gear?
[00:29:47] <tjb1> www.sdp-si.com should have something to help you
[00:30:34] <kwallace> At power out, e-stop should stop axes and spindle as quickly as possible. Warner magnetic brakes can be useful. They activate without power.
[00:31:20] <AR__> i have two polyclutches if anyone wants
[00:31:30] <AR__> they were on big ballscrews
[00:32:27] <kwallace> http://en.wikipedia.org/wiki/Electromagnetic_brake#Power_off_brake
[00:33:25] -!- skunkworks2 has quit [Ping timeout: 248 seconds]
[00:33:39] <tjtr33> yes, deactivate WITH power, its their nature to brake, power turns the brake off, allowing motion
[00:34:37] <AR__> http://www.polyclutch.com/mechanical-slip-clutches/slippers
[00:34:43] <AR__> anyone know what this is even for?
[00:35:06] <AR__> it was on the end of some ballscrews i bought with a pin into the end bearing mount
[00:35:39] <Valen> sounds like a brake
[00:36:05] -!- Brandonian has quit [Quit: Brandonian]
[00:36:13] <AR__> it is a brake failsafe i think
[00:36:53] -!- tjtr33 has quit [Read error: Connection reset by peer]
[00:36:55] <AR__> it just adds friction, doesnt it?
[00:37:18] <Valen> make a decent racket if it activated during motion I imagine lol
[00:37:29] <AR__> lol
[00:37:32] <skunkworks> AR__: picture of gear?
[00:37:44] <AR__> uum
[00:37:57] <AR__> dont feel like going downstairs to get a closeup
[00:37:59] <AR__> but i have a pic
[00:38:01] <Valen> its just a clutch, you could use it in a number of ways
[00:38:02] <AR__> 1 sec
[00:39:07] <AR__> skunkworks, http://i.imgur.com/nn8qT.jpg
[00:39:19] <AR__> they're pretty big, i forget what i measured
[00:39:39] <AR__> diameter is about 2 inches i think
[00:39:45] <AR__> width i think i measured 5/8
[00:40:22] -!- i_tarzan has quit [Ping timeout: 256 seconds]
[00:40:37] <kwallace> Some people with stepper machines have put clutch like bits on the axis screws to dampen resonance.
[00:40:40] <AR__> i need to measure the distance between groove to get a belt, right?
[00:40:49] <AR__> kwallace, ah
[00:40:55] <AR__> these are set really tight
[00:41:10] <AR__> i couldnt turn the screw by hand
[00:41:21] <AR__> i took them off for now
[00:41:29] <PCW_> look like a failsafe so it slips if the ballscrew is stalled
[00:41:45] <AR__> they are on the far end of the screws in the pic i linked to
[00:42:17] <AR__> they had a pin that went into the end block
[00:42:37] <PCW_> OK so a friction lock
[00:42:43] <AR__> so you had to make them slip to move the screw
[00:42:44] <AR__> yeah
[00:43:11] <AR__> these are beefy ballscrews
[00:43:21] <AR__> i feel like i should build a bigger machine
[00:43:44] <PCW_> seems like it would overheat unless the ball screw only turned occasionally
[00:43:56] <AR__> yeah true
[00:44:27] <AR__> i took them off, which was kindof a pain in the ass
[00:44:37] <AR__> the one was jammed on pretty good
[00:44:46] -!- skunkworks has quit [Remote host closed the connection]
[00:45:00] <PCW_> maybe a cheap brake replacement (like leaving the emergency brake on)

[02:32:57] <Connor> To set the CL setting on my speed controller (Torque limit) Set speed control to 30-50%, Set CL to full CCW, Connect a DC ammeter in series with the armature lead. Lock shaft of motor (be sure CL pot is full CCW position). Apply power and rotate the CL pot CW slowly until the ammeter reads 1.5 times motor rating. (do not exceed 2 times motor rating).
[02:33:32] <Connor> I'm not sure I like the idea of locking my motor shaft and applying power.....

[02:50:56] <ReadError> my 28$ piece of aluminum
[02:57:34] <AR__> what size stepper motors would be neeed to move a solid dovetail slide table?
[02:57:48] <AR__> say something like this: http://www.ebay.com/itm/TTC-Y555-008-Compound-Milling-Drilling-Slide-Table-8-x-9-Oval-Base-/221020467188?pt=LH_DefaultDomain_0&hash=item3375d8aff4
[02:58:31] <AR__> ReadError, where did you get that?
[02:58:44] <ReadError> amazon
[02:58:47] <ReadError> ;)
[02:58:52] <ReadError> overnighted for 3.99 too
[02:58:52] <AR__> haha
[02:59:00] <AR__> woah nice
[02:59:04] <AR__> link?
[02:59:59] <kwallace> Do you have the table in your shop?
[03:00:05] <ReadError> not sure how directly link to that size
[03:00:06] <ReadError> me kwallace ?
[03:00:09] <ReadError> thats my back room
[03:00:14] <ReadError> i set it on that to cut
[03:00:47] <kwallace> AR__ wanted to know about stepper size for the table?
[03:01:09] <ReadError> http://www.amazon.com/gp/product/B003U6HUHC/ref=oh_details_o01_s00_i00
[03:01:09] <AR__> yeah just wondering
[03:01:10] <AR__> i dont have it
[03:01:54] <kwallace> I have a theory about motor sizing that I haven't tried yet.

[03:03:53] <AR__> what are you making, ReadError ?
[03:04:01] <ReadError> AR__, just various stuff
[03:04:05] <ReadError> quad rotor parts
[03:04:06] <AR__> o
[03:04:09] <ReadError> i dont sell stuff
[03:04:12] <ReadError> i just make it for fun
[03:05:18] <kwallace> Mount a pulley or drum to the axis screw shaft. Then wrap a rope on it and a weight. Let it drop and see how well the axis moves. Add weight until you get what you want. Calculate the torque from the pulley diameter and use this number to shop for motors.

[03:08:50] <pcw_home> probably need some headroom. Gravity has a somewhat flatter torque/velocity curve than most motors...
[03:09:45] <ReadError> need to figure out how to cut this thing
[03:09:57] <ReadError> i have a hacksaw, jigsaw, one of those reciprocating saws
[03:10:15] <ReadError> picked up some 24tpi blade for the recip saw
[03:10:26] <ReadError> i have an angle grinder but i can see that getting messy
[03:13:32] <AR__> dremel
[03:13:47] <ReadError> yikes
[03:13:48] <jdh> circular saw
[03:14:02] <ReadError> i only have wood blades for that
[03:14:13] <jdh> I use plain carbide blades
[03:14:33] <jdh> chop saw though. Holding a circular saw might be a problem.
[03:14:44] <AR__> hacksaw
[03:15:02] <jdh> cuts fine on mine with whatever blade I have in there.
[03:15:15] <ReadError> chop saw?
[03:15:22] <jdh> miter saw
[03:15:24] <ReadError> is that the one with the big fiber disk
[03:15:42] <jdh> no, plain old carbide tip combination blade
[03:17:19] <kwallace> Using a fence with the circular saw should work fine. Having a couple of teeth engaged would be better, or feed slowly.
[03:18:18] <jdh> http://www.harborfreight.com/10-inch-compound-miter-saw-91995.html
[03:18:34] <jdh> makes an amazingly clean cut
[03:19:29] <ReadError> oh i have one of those
[03:20:19] <jdh> makes nice chips too :)
[03:23:28] <MercuryRising> so i have my Y axis set up with one of those aluminum shaft couplers (the bendy ones for misalignment, as it is a bit misaligned), every once in a while it will skip a step (on one side I have the ceramic/nylon/whatever plastic thing that connects to the motor shaft, on the other I have a piece of vinyl tubing to connect to the lead screw), it is really tight on there, are there any tricks to prevent skipping steps? lowering
[03:23:30] <MercuryRising> acceleration?
[03:29:09] <skunkworks> ware your hearing protection...
[03:29:26] <kwallace> I'd use a belt and pulleys: http://www.wallacecompany.com/machine_shop/bridgeport/00047-1a.jpg
[03:40:44] <Connor> ReadError: I cut a 2" x 4" thick 6061 with mine using a carbide blade...
[03:41:06] <Connor> I waxed the blade on that cut just to be on the safe side.
[03:41:39] <jdh> it's a whole lot faster than my 4x6" bandsaw
[03:41:54] <jdh> cleaner edge also
[03:41:56] <Connor> Don't use a grinding wheel or fiber disk.. you'll melt the aluminum. and will never get through.
[03:42:04] <Connor> heck of allot of chips though.
[03:42:33] <Connor> I wear full face mask and use my vacuum on it.. also drape it with a towel to contain the swarf..
[03:42:41] <Connor> oh. and hearing protection.
[03:42:53] <jdh> take it outside, point it at your neighbors
[03:42:59] <Connor> ROFL.
[03:43:25] <Connor> Don't cut to exact size either.. use the mill to finish...
[03:43:36] <Connor> In most cases anyway..
[03:44:06] <Connor> jdh: Have my spindle broke in (going in forward direction)
[03:44:15] <Connor> Need to break it in reverse now..
[03:44:19] <jdh> how does it sound?
[03:44:37] <Connor> can do around 6800RPM without exceeding 100v on the output.
[03:44:42] <Connor> Load? :)
[03:44:49] <Connor> err. loud
[03:45:02] <jdh> cool. Any problem reading rpm?
[03:45:05] <jdh> via pport?
[03:45:08] <Connor> Get's pretty loud at the higher RPM.. as to be expected.
[03:45:30] <Connor> Just using my Laser Tach.
[03:45:46] <Connor> I have the whole spindle assembly in my office (in my house).
[03:45:53] <jdh> oh, you took off your sensor ?
[03:45:59] <Connor> Easier to monitor it during the break in procedure.
[03:45:59] <jdh> gotcha
[03:46:23] <Connor> I have to make a new mount since converting it to belt drive. plus, need to add the other two sensors..
[03:46:51] <Connor> was thinking about using a encoder direct on the upper shaft of the Tredmill motor.
[03:47:18] <jdh> would probably make life much easier
[03:47:19] <Connor> Kinda like Hoss did.. but, I'm not sure yet.. the only one I have is just A, B. No index.
[03:47:26] <jdh> or via a pulley
[03:47:35] <Connor> via pulley ?
[03:48:03] <jdh> timing belt pulley on shaft & encoder shaft, so it doesn't stick up 7ft
[03:48:39] <ReadError> ohhhh man
[03:48:46] <ReadError> i cut 1 with a hacksaw
[03:49:01] <ReadError> gonna have 1 arm lookin like the terminator if i keep this up
[03:49:51] <jdh> miter saw takes no time
[03:50:07] <ReadError> yea my arm is beat
[03:50:15] <ReadError> ill have to try the miter tomorrow
[03:50:29] <jdh> gives you a good excuse now anyway.
[03:51:15] <ReadError> what about the recip saw?
[03:51:26] <ReadError> seems pretty beefy
[03:51:34] <ReadError> im kind of scared of the miter
[03:51:36] <ReadError> but i can bust it out
[03:51:50] <jdh> mine cuts really well.
[03:52:03] <jdh> not much different than hardwood.
[03:52:25] <jdh> maybe better than hardwood actually
[03:52:33] <ReadError> throw a little lube on it first?
[03:52:35] <ReadError> i dont have wax
[03:52:40] <ReadError> unless you mean candle wax
[03:52:41] <jdh> I never have

[03:55:49] <ReadError> yea
[03:55:57] <ReadError> im going to use wd40 to cut this stuff on the mill
[03:56:01] <ReadError> or 3-in-1
[03:56:05] <ReadError> since i dont have a flood table

[04:16:47] <ReadError> pretty happy with it?
[04:16:54] <Connor> So far.
[04:17:57] <ReadError> how hard was the Z axis motor to do ?
[04:18:22] <Connor> not that hard. would have been easier if I did ball screws.
[04:19:17] <ReadError> got any pictures of the conversion process?
[04:19:28] <ReadError> im looking for something a bit bigger here in a bit
[04:20:02] <Connor> Some.. You can look through my thread.. Followed Hoss's plans for the most part.
[04:20:05] <ReadError> i still have alot to learn though
[04:20:17] <ReadError> im afraid to undertake a conversion like that at this point

[04:21:08] <jdh> I did Z ballscrew, xy stock, then used that to cut the parts for the xy ballscrews
[04:21:17] <ReadError> oh you got one too jdh ?
[04:21:23] <jdh> yeah
[04:21:31] <Connor> I had to have a friend turn down the Z Shaft Adapter for me..

[04:38:58] <Connor> the 5mm one from LMB are fine
[04:39:04] <jdh> lower is faster

[04:39:58] <jdh> assuming you can move the table fast enough to make it worthwhile

[16:20:31] <IchGuckLive> in hand mode it is on the plate

[20:14:32] <JT-Shop> <JesusAlos_> I need create a time bar in the interface
[20:14:33] <JT-Shop> <JesusAlos_> this time mus control a pause stop control
[20:14:33] <JT-Shop> <JesusAlos_> in XY axis machine
[20:14:33] <JT-Shop> <JesusAlos_> must do a pause time when it detect a change direction more than 10º
[20:14:33] <JT-Shop> <JT-Shop> much better to ask on #linuxcnc channel
[20:14:34] <JT-Shop> <JT-Shop> sounds above my pay grade or I don't understand
[20:14:36] <JT-Shop> <JesusAlos_> I looking for some programmer
[20:14:38] <JT-Shop> <JesusAlos_> I pay it
[20:14:40] <JT-Shop> <JT-Shop> I only dabble in python and barely know how to spell C
[20:14:42] <JT-Shop> <JT-Shop> is the change in direction programmed in with G code?
[20:14:44] <JT-Shop> <JesusAlos_> yes
[20:14:46] <JT-Shop> <JesusAlos_> I think
[20:14:48] <JT-Shop> <JesusAlos_> yes in Gcode direction
[20:14:52] <JT-Shop> <JesusAlos_> when change the X to Y or Y to X
[20:14:54] <JT-Shop> <JesusAlos_> mus be pause
[20:14:56] <JT-Shop> <JT-Shop> just put a G4 for the pause
[20:14:58] <JT-Shop> <JesusAlos_> is a lott work
[20:15:00] <JT-Shop> <JesusAlos_> there are a lott change direction
[20:15:02] <JT-Shop> <JT-Shop> at this point my WAG is what your asking for sounds like a change in the interperter which is a lot of work and above my abilities
[20:15:04] <ReadError> is JesusAlos the guy cutting foam
[20:15:05] <JT-Shop> <JT-Shop> make a python script to parse the G code file and add the G4P as needed
[20:15:07] <JT-Shop> <JesusAlos_> but the pause don't do automatic in change direction
[20:15:08] <ReadError> that wanted to pause
[20:15:09] <JT-Shop> <JT-Shop> you the hot wire guy that the wire is not hot enough to keep straight?
[20:15:11] <JT-Shop> skunkworks: there you go
[20:15:19] <JT-Shop> I think so
[20:15:44] <ReadError> is there a pause gcode i can throw in?
[20:15:48] <ReadError> similar to a toolchange
[20:15:52] <ReadError> or would toolchange be easiest
[20:16:09] <jdh> you can pause for a time, or pause until a digital input
[20:16:11] <skunkworks> mo
[20:16:13] <JT-Shop> I think he want's it automatic
[20:16:47] <skunkworks> oh - he want to add a pause depending on how sharp the angle is... I vaugly remember that
[20:17:10] <JT-Shop> sounds like a machine issue to me
[20:17:34] <JT-Shop> if you pause to wait for the wire to catch up the ends will over melt

[20:21:20] <JesusAlos_> yes JT-Shop, but customer need this function
[20:21:58] <JT-Shop> so it don't matter if the foam melts while the wire catches up?
[20:23:19] <JesusAlos_> no
[20:23:53] <JT-Shop> use G61 and set the acceleration low enough to give the wire time to catch up
[20:24:03] <JesusAlos_> to cut comb hig density is necesary
[20:24:28] <JesusAlos_> not enought
[20:26:40] <JesusAlos_> can continue tomorow
[20:26:45] <JesusAlos_> ?
[20:26:53] <JesusAlos_> i try video
[20:29:26] <JT-Shop> JesusAlos: might I suggest a three pronged approach to this problem... 1 as you are doing now dialog on the IRC, 2 post on the forum, 3 send a message to the mailing list. This way you reach everyone that monitors the EMC world

[20:31:54] <JesusAlos> yes. No change in gcode
[20:32:12] <JesusAlos> just modific EMC
[20:32:24] <JT-Shop> what does the other machines use for path control?
[20:32:25] <JesusAlos> EMC software
[20:32:36] <Connor> I think you would be better off running a post processor on the gcode at the machine level...
[20:33:25] <JT-Shop> JesusAlos: does the code contain any G61 or G64 words?
[20:33:26] <JesusAlos> but every customer use different software
[20:33:43] <JesusAlos> JT-Shop
[20:33:46] <JT-Shop> oh different machines at different customers
[20:34:44] <JesusAlos> there are a lott kind CAM softwares
[20:34:48] <JT-Shop> how do you expect different G codes from different software to work?
[20:35:08] <JesusAlos> is no easy for me do a different postprocessor
[20:35:21] <JT-Shop> and they all use Post Processors and that is the function of the post processor to generate a g code to suit the machine
[20:36:14] <JT-Shop> how do you expect EMC to run code from every CAM program with different post processors?

[22:02:29] * r00t4rd3d draws stuffs
[22:03:07] <pfred1> are photo editing software the best applications for drawing in?

[22:04:04] * pfred1 used to draw on paper with pencils
[22:04:20] <r00t4rd3d> relic
[22:04:25] <pfred1> I don't have the time for that today though
[22:05:13] <pfred1> I got a B+ in my college drawing class so I must not have been bad at it
[22:05:44] <pfred1> I actually thought I drew better than the top in the class but I think the teacher just liked the subject matter that kid picked better than mine

[22:09:07] <pfred1> it is actually broken one of the bones is missing on it
[22:09:09] <r00t4rd3d> thats a crash
[22:09:32] <pfred1> but that is actually how it was
[22:09:49] <pfred1> I wonder whatever happened to that thing?

[22:12:10] <pfred1> it is still a mental trick to be able to draw things accurately
[22:13:44] <pfred1> I took it upon myself when I was younger to learn it
[22:14:51] <tjb1> Nothing wrong with my G540…relay power bleeding into G540 and powering it
[22:15:23] -!- pjm has quit [Ping timeout: 252 seconds]
[22:15:30] <pfred1> I have a bleed power problem with my BOB
[22:16:25] <pfred1> like if my BOB is unpowered but it is connected to the parallel port the power LEDs on it glow a little
[22:16:44] Cylly is now known as Loetmichel
[22:19:26] <tjb1> Mine activates the output when the G540 loses power :P
[22:19:37] <tjb1> If he would have said that to begin with I wouldnt have needed to send it in...
[22:19:54] <pfred1> my back feed power doesn't actually do anything so I never bothered troubleshooting it
[22:20:15] <pfred1> it still bugs me that it does it though just not enough to fix it
[22:20:33] -!- FinboySlick [FinboySlick!~shark@squal.net] has joined #linuxcnc
[22:20:56] <tjb1> I either get a 48v relay or shut both power supplies off at the same time
[22:22:27] <pfred1> 48v relay sounds like a bit of an oddball
[22:22:53] <pfred1> they make them but they're not exactly commonplace

[22:25:57] <pfred1> tjb1 I had a neon indicator bulb go on me once and I didn't have any spares so I made an LED work on 120VAC
[22:26:13] <tjb1> Im not too electronics savvy
[22:26:56] <pfred1> me saying i made an LED work on 120VAC isn't saying I've very electronics savvy either
[22:27:08] <pfred1> but I made it work anyways
[22:27:42] <pfred1> it is amazing what they're charging for neon bulbs today!
[22:28:55] <Loetmichel> pfred1: al led as led or as incandescent lighting?
[22:28:56] <Loetmichel> ;-)
[22:29:54] <pfred1> Loetmichel light emitting diode
[22:30:19] <Loetmichel> pfred1: i meant: did the led emit light cold or because it was glowing? ;-)
[22:30:30] <pfred1> the only reason I did it is because I had the cabinet already drilled for the indicator lamp
[22:31:39] <pfred1> Loetmichel I'm not following you I'm afraid
[22:31:43] <Loetmichel> <- been there, accidentally switched the intended 10k resistor with a 100 R... "wha the hell tis GREEN led is glowing orange?" *touch* *PSSSSS* "AHHHH"
[22:31:44] <Loetmichel> ;-)

[22:32:37] <FinboySlick> Loetmichel: The reflex following 'what the hell' should never be to touch the thing.
[22:32:40] <pfred1> I forget what dropping resistor I had to use maybe 2.7K? I figured it was going to dissipate 2 watts or so so I used a 5 it got so hot I wished I'd used a 10W
[22:33:01] <FinboySlick> Loetmichel: Sort of in the lines of: "Hold my beer and check this out."
[22:33:02] <pfred1> but it works to this day so I don't worry about it looks good too

[22:34:08] <tjb1> Erm, math
[22:34:15] <pfred1> yeah but it works
[22:35:07] <Loetmichel> pfred1: 6kOhms. and better use a fitting capacitive choke instad, doesent get so warm ;-)
[22:35:51] <pfred1> Loetmichel I know there are better ways but I just wanted to fill a hole in a chassis and I didn't want to have to be doing it at all
[22:36:22] <Loetmichel> i see
[22:36:49] <pfred1> the dream would have been to have had a spare neon bulb on hand
[22:37:57] <pfred1> I got to admit that LED indicator is beautiful today
[22:38:24] <pfred1> even if it does dissipate 2 watts when it runs

[23:51:53] <pfred1> we shoot all the time by me
[23:52:26] <pfred1> pop density is less than 40 per square mile so you're not likely to hit anyone
[23:52:50] <andypugh> It was 80 per square mile, but you know....
[23:52:59] <pfred1> if I shoot to the west a bullet will hit the ground before it hits naytyhing manmade
[23:53:14] <pfred1> there is nothing for miles in that direction
[23:54:03] <pfred1> heck I probably couldn't get a bullet off my property in level flight
[23:54:17] <pfred1> too many trees
