[00:00:13] <furrywolf> just sprayed the lemon, grape, and some of the peppers (mostly by overspray) with dr. bronner's peppermint soap in water...
[00:00:24] <furrywolf> will let it sit a bit then hose it all off

[00:56:35] <furrywolf> I have scale insects
[00:57:09] <furrywolf> the soap seems to have been quite effective, even after only two days of using it... given as the scale insects seem to wash off now, I figure it must have killed them.
[00:57:16] <furrywolf> and it got most of the sooty mold off
[00:58:41] <furrywolf> just rinsed everything... killed one of my tomato starts by accident. d'oh. accidentally clipped it with the hose nozzle set to "pepper" instead of "tomato". (i.e. hit it with a full-force stream, which peppers don't mind, but makes tomatos shred instantly)

[01:24:10] <renesis> lemon oil supposedly dissolves their little breathing hole membranes
[01:24:45] <renesis> but it evaporates really quickly unless its in some sort of oil or wax base, makes it kind of nasty to spray on stuff

[01:44:26] <renesis> shrug, it wont fuck you up at all but it dissolves bug lungs
[01:45:20] <renesis> but the stuff you can get at hardware stores is in some waxy base so it doesnt evaporate immediately, have to clean it up after or it turns yellow, sticky

[01:55:44] <furrywolf> just checked on the electrolysis rust removal experiment... chain binder is looking pretty good. the black powder is hard to get off. it re-rusts INSTANTLY. like, I tried wire brushing one part of it to get some residual paint off, and the other end got a light flashing of surface rust during the 2-ish minutes I spent.
[01:55:57] <furrywolf> I'll probably toss it back in the bucket, but I'm not in the mood to deal with it now.

[01:58:45] <Cromaglious> the flash rust comes off soon as you throw some oil on it
[01:58:59] <furrywolf> I'm planning on paint, so no oil.
[01:59:44] <furrywolf> got a c-clamp in the bucket now... found it under the stairs in the greenhouse. I was wondering where it went! was nice, all rusted to shit now.
[02:00:20] <Cromaglious> using oil based paint?
[02:00:27] <furrywolf> spray
[02:00:31] <furrywolf> rattle can
[02:00:45] <Cromaglious> rustoleum?
[02:00:46] <furrywolf> I'm not going to brush on paint on a rusty old chain binder. :)
[02:01:03] <furrywolf> the surface looks a bit sponge-like... it was pretty rusty.
[02:01:45] <Cromaglious> rustoleum has fish oil in it, so throw a bit of mineral spirits on it
[02:02:12] <Cromaglious> which is a really light oil
[02:03:25] <furrywolf> also, I've learned that anodes get eaten stupidly quickly, and that alligator clips connected to the anode need to be several inches above the water level, or they get eaten too.

[02:03:41] <furrywolf> I had one only about 3/4" over the waterline, and it's gone.
[02:04:56] <Cromaglious> yep... hehehe white vinegar also works, with power or by itself
[02:11:06] * furrywolf tries uploading a few pictures, so it'll be about ten minutes
[02:11:34] <Cromaglious> you ever get new pictures of your mill/lathe?
[02:11:58] <furrywolf> no
[02:12:12] <furrywolf> that project is on hold pending availability of money, so it's sitting in storage.
[02:12:49] <Cromaglious> what's the most important part you need for it to get going?
[02:13:00] <Cromaglious> besides money
[02:13:25] <furrywolf> time
[02:13:27] <furrywolf> lol
[02:13:40] <Cromaglious> or time or steam or electricity
[02:13:53] <furrywolf> a 7i76e
[02:14:20] <furrywolf> I think using a parallel breakout board is a dead-end, and I don't want to keep wiring more stuff that I'll end up redoing later.
[02:16:05] -!- anth0ny has quit [Quit: anth0ny]
[02:16:23] <furrywolf> I also need an enclosure. right now all the electronics are sitting next to it and piled on it.
[02:16:46] -!- per_sonne_ has quit [Ping timeout: 272 seconds]
[02:16:55] <Cromaglious> Find a 20mm ammo can
[02:17:08] <furrywolf> I got my chinese 4-pin plugs to connect the steppers with, so that's taken care of. they seem adequate.
[02:17:14] <furrywolf> I have a half dozen 20mm ammo cans. lol
[02:18:10] <Cromaglious> mount a piece of plywood to the lid and then cut cooling slits or holes on the sides.. pop the top, slide out the board
[02:18:14] <furrywolf> I'm thinking more of a nice aluminum box with the large, flat side hinged....
[02:18:21] <furrywolf> probably end up making one
[02:18:45] <furrywolf> I could make the lid out of plexi so I can see my shiny wiring.
[02:18:47] <Cromaglious> mount everything through the lid
[02:19:11] * furrywolf is still waiting for three images to upload
[02:20:12] <furrywolf> http://fw.bushytails.net/rust%20removal%20surface%2001.jpg http://fw.bushytails.net/rust%20removal%20pipe%20anode%2001.jpg http://fw.bushytails.net/rust%20removal%20anode%20clip%2001.jpg
[02:21:06] <Cromaglious> I have a large NEMA 3R enclosure big enough to mount 19" rails in, plus I have 5 racks of various sizes.. from 28" tall to 7' tall
[02:21:45] <Cromaglious> 3 DEC alpha 6' racks are my nicest
[02:22:09] <furrywolf> yeah, my box is going to be about 18x18x8".
[02:22:17] <furrywolf> maybe smaller
[02:23:00] <Cromaglious> the 28" is a telco mount on the wall for PBX / MOH, etc... front opens, then the middle swings away from the wall to get access to the back
[02:23:52] <furrywolf> I want to mount my stepper drives on some beefy 45-degree aluminum extrusion, so I can get to all the terminal screws without having to remove every drive.
[02:24:06] * furrywolf has not yet located such extrusion
[02:24:49] <Cromaglious> I got a TB6600 driver that all the wiring is at one end. and the heat sink is the mounting flange
[02:25:27] <Cromaglious> and they're plugs to boot
[02:25:49] <furrywolf> each of my drives draws more power than all four axis on a tb6600 board. :P
[02:25:57] <Cromaglious> 6c,4c to stepper, and 2c for power
[02:27:25] -!- AR_ has quit [Ping timeout: 264 seconds]
[02:27:47] <furrywolf> mine don't have plugs, so I need to either mount them flat (takes up lots of area), or mount them overlapping at an angle... if I put them on 90 degree brackets, there's no way to get to the screws on any but the end one.
[02:27:53] <Cromaglious> wah.... And you consider yourself the broke one..
[02:27:56] <furrywolf> probably what I'll end up with, however.
[02:28:13] <furrywolf> yes, I got used, outdated drives on ebay.
[02:28:14] <furrywolf> heh
[02:28:30] <furrywolf> old centent cn0165s
[02:28:52] <Cromaglious> I got the old steppers out a printer I tore apart
[02:29:15] <furrywolf> mine don't match, because I couldn't find three matching used, cheap steppers on ebay. heh.
[02:29:18] <Cromaglious> 1ea NEMA23, 2ea NEMA17
[02:29:30] <Cromaglious> and none of mine match either
[02:29:59] <furrywolf> x and y match, z is different. figured that made the most sense when I had one pair and one different.
[02:30:40] <Cromaglious> Biggest, Y, middle, X, smallest Z based on MASS
[02:31:10] <furrywolf> lol
[02:32:14] <furrywolf> while there is a correlation between mass and strength, it's not direct, nor one-way. :)

[02:40:23] <Cromaglious> well since I'm using tb6560 and tb6600 drivers, it's more so for me

[02:43:14] <furrywolf> heh, mine does have real leadscrews. just acme, nothing fancy. and one had a 10 degree bend in it...
[02:45:52] <furrywolf> I need a faster internet connection. being able to download things instantly to my linode then taking the next day to get them here is tiresome.
[02:46:24] <furrywolf> "13,700,469 30.6M/s in 0.4s" why can't I do that at home? heh
[02:46:26] <Cromaglious> I'm gonna leave room to upgrade to ball screws
[02:46:55] <Cromaglious> I sure can't with steppers

[02:48:27] * furrywolf is trying to download some Life of Agony, having decided they're a quite good band (and have a hot tranny frontwoman), but internet connection sucks.
[02:48:41] <Cromaglious> first thing I have to do is upgrade the 3040 at the space to a higher gantry so I can fit a 4x4 under it on a 45 degree angle so the A axis is absofreaking usuable
[02:49:44] <Cromaglious> I can then get Oak 2x4's off pallets to make my bearing carriers
[02:50:16] <furrywolf> ... wood?
[02:51:17] <Cromaglious> once I get mine up and running in oak and birch, I can then start making piece in Aluminum to replace the wood parts, then down the road I can upgrade the AL to stee;
[02:51:33] <Cromaglious> yes hardwood
[02:51:53] <Cromaglious> brazillian eppe is harder and stiffer than AL
[02:53:21] <Cromaglious> certain piece will be Aluminum from the get go
[02:53:23] <furrywolf> how about dimensionally stable with time?
[02:53:41] <Cromaglious> old pallet oak is very stable
[02:54:42] <Cromaglious> if I hit the lottery I'll get a Bridgeport
[02:55:12] <Cromaglious> and run it off a VFD
[02:56:15] <Cromaglious> anythreading I'll do probably be thread milling, not hard tapping unless done by hand

[16:17:59] <crazy_imp> is it possible to "unroll" gcode and save it?
[16:18:03] -!- swingley has quit [Remote host closed the connection]
[16:18:18] <archivist> unroll...er why
[16:18:38] <crazy_imp> (asking because i want to delete some holes in a grid and don't want to code it :D)
[16:19:13] <archivist> add a where clause to not drill those
[16:20:24] <archivist> or grep the gcode and delete where drill those locations
[16:20:50] <crazy_imp> the code is compact with some loops and a sub routine
[16:21:23] <crazy_imp> that's why i'm asking if it's possible to save the code from linuxcnc/axis after loading it
[16:21:43] -!- sumpfralle has quit [Ping timeout: 250 seconds]

[16:34:57] <_methods> just use block delete
[16:35:30] <archivist> coded loops cant do that
[16:36:01] <_methods> why not?
[16:36:31] <archivist> because that would lose rows/columns of holes not odd holes
[16:37:15] <_methods> yea i guess i'm not sure how his code is set up then
[16:39:22] <crazy_imp> http://pastebin.com/87f1BnhZ
[16:40:13] <_methods> haha i remember when i used to code stuff like that
[16:40:40] <archivist> it is the only way !
[16:40:58] <_methods> maybe if you're the only one using your code
[16:41:07] <archivist> for anybody doing regular pattern type work
[16:42:39] <archivist> for me making gears it is a rotate A, cut along some axis, rinse repeat n teeth

[18:15:19] <zeeshan> lol
[18:15:21] <Jymmm> shall I continue?
[18:15:33] <Jymmm> i do have pi to a million digits
[18:15:35] <zeeshan> thats only going to get you _so_ close
[18:15:41] <LeelooMinai> Jymmm: You have a typo at 253rd pllace
[18:15:47] <zeeshan> rofl LeelooMinai
[18:15:47] <zeeshan> haha
[18:16:29] <Tom_itx> wtf was that all about?
[18:16:42] <Jymmm> I really do have pi to a million digits, been wanting to engrave it in grantire, but smaller than 4pt is just not legible.
[18:16:58] <Tom_itx> engrave it somewhere besides here pls
[18:17:00] <zeeshan> you only need like 6 digits to get close to most engineering solutions
[18:17:00] <zeeshan> :)
[18:17:05] <Tom_itx> i have a few thoughts where
[18:17:27] <Jymmm> Tom_itx: quit yer bitchin old man!
[18:17:41] * Jymmm steps on Tom_itx's lawn
[18:17:57] <Tom_itx> just don't need to see a bunch of useless numbers nobody would practically use
[18:18:11] <zeeshan> SPEAK about yourself tom!
[18:18:28] <Tom_itx> what do you have that needs that accuracy?
[18:18:44] <Tom_itx> the tread on your tires?
[18:18:47] <zeeshan> yes
[18:18:52] * LeelooMinai looks at some circles made by Tom_itx and they look like eggs
[18:19:47] <Tom_itx> you'd need equipment i dare say nobody here owns to measure that accuracy anyway
[18:20:15] <Jymmm> Nope you can get micron stuff off ebay
[18:21:26] <zeeshan> do you guys know what pi is
[18:21:35] <Tom_itx> apple or cherry?
[18:21:40] <zeeshan> you can find it somewhat accurately using your DRO!
[18:21:44] <Jymmm> tasty
[18:22:13] <Tom_itx> 22/7
[18:23:11] <Tom_itx> Jymmm what's that in binary?
[18:23:50] <zeeshan> wut is 22/7
[18:24:07] <zeeshan> that aint even close to the 3rd decimal place!
[18:25:22] <Tom_itx> pi is the ratio of the diameter to the circumference
[18:25:35] <Tom_itx> close to 22/7
[18:25:50] <zeeshan> yea like P = πD
[18:26:32] <Jymmm> Tom_itx: You bitched about Base10 and now want it in Base2 ?!
[18:26:40] <zeeshan> rofl Jymmm haha
[18:26:50] <Tom_itx> hehe
[18:26:57] <zeeshan> how would you even represent it?
[18:27:08] <zeeshan> break it into multiple double precision float?
[18:27:14] <Tom_itx> if you printed it in rows maybe it would paint a picture of jesus
[18:27:53] <Jymmm> Fuck, just loading the text file takes a moment as it is.
[18:28:00] <zeeshan> do you know about the hidden message in pi?
[18:28:15] <zeeshan> 3.14 <- mirror it
[18:28:17] <zeeshan> what do you get?
[18:28:21] <zeeshan> PIE!
[18:28:24] <Jymmm> rotten fruit + sugar
[18:29:59] <Tom_itx> go to your old HS and write it out on the chalkboard
[18:31:01] <zeeshan> you know what i didnt know
[18:31:05] <zeeshan> helium is a finite resource?
[18:31:14] <zeeshan> apparently it leaks to space?
[18:31:23] <zeeshan> i still feel like that is a whole lot of bullshit
[18:31:27] <pcw_home> There's a lot in the sun

[19:16:15] <heathmanc1979> So, i have a dc servo setup using AMC 30A8 amplifiers. I have them tuned decently, but when traversing the table, ocassionally i get a following error
[19:16:32] <heathmanc1979> What is most likely to get rid of that?
[19:16:51] <heathmanc1979> Following error is set at default .0005
[19:18:01] <heathmanc1979> This is at 30ipm
[19:18:26] <andypugh> Maybe you are right on the limit of the max motor speed?
[19:18:35] <heathmanc1979> Happens only on direction changes
[19:18:55] <andypugh> Maybe you are right on the limit of the max motor accelleration.
[19:19:20] <heathmanc1979> Acceleration is set at 1"/sec
[19:19:41] <heathmanc1979> I could try turning it down i suppose.
[19:19:53] <andypugh> Hmm, that actually sounds rather low.
[19:20:01] <zeeshan> mines like 10 in/s^2
[19:20:18] <zeeshan> heathmanc1979: got a post of your tune?
[19:20:21] <zeeshan> pic
[19:20:37] <heathmanc1979> I know. Think it is a tuning issue. I was getting a following error when enabling the machine to begin with
[19:20:43] <andypugh> heathmanc1979: Which kins module are you using?
[19:20:55] <zeeshan> in the Z axis?
[19:21:05] <heathmanc1979> No, x axis
[19:22:14] <heathmanc1979> Andypugh, this is just a default install, with a 4i69 and 7i33
[19:22:33] <andypugh> So, you are using trivkins?
[19:22:38] <heathmanc1979> Yes
[19:23:52] <andypugh> Hmm. With non-trivial kins you need accel and velocity in the [TRAJ] section or there are f-errors on decel. But that isn’t the case with trivkins AFAIK
[19:25:01] <heathmanc1979> I dont have a tuning screenshot, because i have done this by hand so far, havent completely figured out halscope to look at it
[19:25:27] <zeeshan> by hand? :)
[19:26:06] <heathmanc1979> Lol, without using halscope, plugged in values until thing started shaping up
[19:26:30] <zeeshan> you really need halscope
[19:27:47] <heathmanc1979> I know. Just havent sorted it out yet, searching for a good tutorial
[19:28:32] <zeeshan> http://i.imgur.com/YGjs38b.png
[19:28:48] <zeeshan> you just need to plot out axis.x.f-error
[19:28:54] <zeeshan> and analogoutx
[19:29:07] <zeeshan> and setup so that you trigger off analogout0
[19:29:35] <pcw_home> Are the drives running in velocity mode? (that is, do they have tachometer feedback from the motors)
[19:30:17] <heathmanc1979> No tach
[19:30:31] <heathmanc1979> Just 1000 line encoders
[19:30:41] <pcw_home> OK so drives must be in torque mode
[19:31:16] <pcw_home> (or at least they should be set to torque mode)
[19:31:43] <heathmanc1979> Lol, might be a problem then. They are in voltage mode
[19:32:22] <pcw_home> voltage mode should be OK also
[19:32:32] <pcw_home> just not velocity mode
[19:33:09] <heathmanc1979> Ok, drives only have current, voltage, and tach(velocity)
[19:34:40] <heathmanc1979> Not finding this analogoutx
[19:34:46] <andypugh> I would expect current to work better than voltage. But with no experience either way.
[19:35:53] <andypugh> heathmanc1979: Do you really mean 4i69?
[19:35:54] <pcw_home> voltage mode is is a bit easier to tune because it has inherent damping of high frequency vibrations
[19:35:58] <heathmanc1979> Yes
[19:36:07] <heathmanc1979> Pci 104 on a sbc
[19:36:43] <pcw_home> but tuning is a bit odd because its about 1/2 way between velocity and torque (current) mode
[19:36:55] <andypugh> I wasn’t aware that LinuxCNC + 4i69 worked
[19:37:11] <heathmanc1979> Lol, it does, when you have the firmware
[19:37:19] <heathmanc1979> And without pncconf
[19:37:51] <andypugh> Anyway, I think you are probably sending PWM to the drives rather than analogue out?
[19:37:57] <pcw_home> pncconf will work fine (just tell it its 5i20)
[19:38:11] <heathmanc1979> Nope
[19:38:25] <heathmanc1979> Connectors are different, p1,3,4
[19:38:39] <pcw_home> not important
[19:38:58] <heathmanc1979> Essentially that is what i did, then changed the config
[19:39:11] <heathmanc1979> Replacing 5i20 with 4i69
[19:39:21] <heathmanc1979> And that got me started
[19:40:26] <heathmanc1979> Damn halscope!!!
[19:40:52] <pcw_home> they all use the same pinout files so all the GPIO will be setup properly, only connectors names will wrong in pncconf
[19:41:22] <heathmanc1979> Right, no biggie. The tuning is the issue now
[19:42:29] <pcw_home> Tuning voltage mode is a bit like velocity mode but you need to add D (velocity mode typically doesn't use D)
[19:43:43] <andypugh> Accelleration from high speed will be less (for the same PID output) at high speed, so the lack of compensating D could well be the problem.
[19:44:49] <heathmanc1979> So, to best see this in halscope, what channels do i need to see
[19:44:51] -!- furrywolf [furrywolf!~randyg@72-57-238-176.pools.spcsdns.net] has joined #linuxcnc
[19:45:03] <pcw_home> voltage mode need as much D as is stable (running the servo loop faster will allow mode D)
[19:45:04] <pcw_home> the amount of P you can use depends on the amount of D
[19:45:17] <pcw_home> allow more D
[19:45:24] <andypugh> heathmanc1979: We don’t even know which channels you have :-)
[19:45:52] -!- amiri has quit [Ping timeout: 255 seconds]
[19:46:02] <andypugh> But axis position, axis f-error, encoder velocity, PID output I would stat with.

[20:51:10] <MrFluffy> Hi, hoping someone here can help me clear up my utter confusion. I have linuxcnc conversion on a bridgeport interact, the spindle is controlled by a vfd, which I supply 0-10v analog voltage. I have a daughter board (spindleV4 from diycnc.co.uk) which takes step input and converts it to 0-10v analog out. And I have 3 pins on my second parallel port connected as spindle on, direction, and speed. basic question, is this a pwm setup
[20:51:22] <Deejay> gn8
[20:51:33] <MrFluffy> I can make the spindle go round and change direction, but cannot figure out how to control the spindle speed...

[20:54:35] <pcw_home> Some 0 --> 10V converters are PWM some are PFM (for step rate controlled voltage) you need to look at the specs of your daughtercard
[20:55:37] <pcw_home> heathmanc1979: its set in the hal or ini file (servo period)
[20:55:57] <MrFluffy> The manual for the daughterboard says :- This is achieved by converting stepper pulses from the parallel port into a voltage level suitable for the spindle drive board. Is that PFM?
[20:55:59] <heathmanc1979> Set it to 200000
[20:56:12] <dirty_d> any ideas on the easiest way to attack a potentiometer or something to the throttle on this?
http://ad-discountperformance.com/images/mikunicarb.JPG
[20:56:41] <pcw_home> yes sounds like PFM

[21:01:45] <Cromaglious> Whats the otherside of the throttle shaft look like?
[21:03:59] <Cromaglious> look thru the Throttle position sensors and find one that looks like it would hang on the shaft. then make a bracket to hold it. You could use the 4 screws holding the diaphram cover to mount it
[21:05:33] <zeeshan> anyone know much about date codes on welding tanks?
[21:05:38] <furrywolf> the other end often doesn't stick out of the carb. just make a bracket on the end you do have that fits any random vehicle's throttle position sensor. (except volvo. they don't work.)
[21:05:54] <furrywolf> zeeshan: they should be a plain date, nothing fancy...
[21:05:58] <zeeshan> its not man
[21:06:01] <zeeshan> check this out
[21:06:03] <Cromaglious> that carb is setup for a vertical cable pull, so there might be someplace on the cable guide to mount it
[21:06:10] <zeeshan> my argon tank is regular numbers
[21:06:15] <zeeshan> like "month" "year"
[21:06:43] <Cromaglious> all my tanks are way past cert date
[21:06:47] <MrFluffy> Some of the stamping will be the tare of the cylinder too zeeshan
[21:07:33] <furrywolf> dirty_d: what're you building?
[21:07:36] <MrFluffy> tare = amount of gas to add to consider it filled. no idea what the rest of the world uses as a encoding scheme, but Ive lived in the uk and now france and I am sure both use different syntax.
[21:07:46] <zeeshan> http://i.imgur.com/rKhrOeZ.jpg
[21:07:48] <zeeshan> this i understand
[21:07:52] <zeeshan> you can see it was made in 1937
[21:08:00] <zeeshan> and last date on this is 1963
[21:08:08] <zeeshan> http://i.imgur.com/kh9i070.jpg 91+ on this one
[21:08:13] <dirty_d> furrywolf, EFI for a jet ski
[21:08:14] <zeeshan> now here is where i get confused, that other number.
[21:08:22] <furrywolf> MrFluffy: eh? tare is usually empty cylinder weight, no?
[21:08:24] <zeeshan> it says 07 153 97
[21:08:32] <zeeshan> http://i.imgur.com/DviABCz.jpg
[21:08:34] <furrywolf> dirty_d: so you're going to use the carb for just a throttle body?
[21:08:34] <zeeshan> this is the last entry.

[21:08:40] <dirty_d> furrywolf, exactly
[21:08:44] <zeeshan> + and *
[21:08:49] <zeeshan> + means 10 year cert
[21:08:54] <zeeshan> * means you can overfill by 10%

[21:08:59] <zeeshan> but im not sure what the heck that number means
[21:09:05] <zeeshan> im hoping it means it was last certified in 2008.
[21:09:10] <zeeshan> so that means itll expire in 2018
[21:09:10] <dirty_d> furrywolf, i think it would be more work getting it to fit
[21:09:46] <furrywolf> going to use spfi or mpfi?
[21:09:48] <dirty_d> furrywolf, i was thinking maybe glue a magnet somehow to the part that rotates
[21:09:57] <dirty_d> and then some kind of pickup
[21:10:08] <dirty_d> just one injector
[21:10:15] <furrywolf> so single-point.
[21:10:20] <dirty_d> ill probably just drill a hole in the carb somewhere
[21:10:24] <dirty_d> yea
[21:11:06] <MrFluffy> I saw a mikuni with some kind of tps retrofitted, it had a snail shaped cam on the throttle spindle outboard of the cable, and a plunger type tps mounted on a bracket with a floatbowl, someone does them as some kind of kit to retrofit ignition mapping stuff or something

[21:15:26] <furrywolf> that should be within the range of a small car maf sensor
[21:16:20] <zeeshan> http://lincolnelectric.com/en-us/equipment/Pages/product.aspx?product=K2473-2
[21:16:21] <zeeshan> anyone got this?
[21:16:35] <dirty_d> it was for a 2.4L nissan
[21:17:22] <Cromaglious> zeeshan, AHHH HELL NO! I got my mig for $99
[21:17:37] <dirty_d> i just have a stick and broken tig
[21:17:37] <zeeshan> i dont want a crappy mig to be honest
[21:17:50] <zeeshan> im looking at the 180c cause its continuously adjustable
[21:17:53] <zeeshan> which will help for thinner stuff
[21:18:02] <dirty_d> but its only half broken, i can hook up the stick welder to the tig welder and still use scratch start to weld
[21:18:19] <dirty_d> no current control, but good enough
[21:19:16] <furrywolf> "Toughest PC Board Protection in the Industry – ‘Potted’ to seal sensitive components from the environment" aka "Requires entirely assembley to be replaced every time".
[21:19:35] <Cromaglious> Kragen (O'Reilly now) fluxcore mig, and a Harbor Freight 131 mig
[21:19:52] <dirty_d> i wouldnt even bother with a mig welder
[21:20:00] <MrFluffy> Sorry, cant find the pic of it, it struck me as a bad idea anyway to be honest, just it was easy to retrofit to a carb without worrying about mounting. Id just fit a throttle body, you can run a bigger venturi without hurting performance anyway with efi.
[21:20:17] <zeeshan> why not dirty_d?
[21:20:18] <furrywolf> there is no such thing as "fluxcore mig".
[21:20:34] <Cromaglious> my 131 does MIG or fluxcore
[21:20:36] <zeeshan> mig is such a bullshit term though
[21:20:41] <zeeshan> metal inert gas
[21:20:46] <MrFluffy> I think he means flux coated wire... aka gasless.
[21:20:47] <zeeshan> how is co2 argon innert
[21:20:49] <zeeshan> inert :P
[21:21:28] <furrywolf> dirty_d: I'd still suggest poking around at the junkyard for a small car throttle body, see if you can find one that looks like a close fit.
[21:21:30] <Cromaglious> meaning no oxygen or hydrogen
[21:21:47] <dirty_d> zeeshan, you can do more with a tig welder
[21:21:52] <zeeshan> dirty_d: no you cant
[21:21:53] <zeeshan> lol
[21:21:55] <dirty_d> mig is more for high production work
[21:21:55] <zeeshan> i have one.
[21:22:02] <zeeshan> a mig is a lot easier for fabrication
[21:22:04] <furrywolf> googling shows you can get shiny new ones (even 44mm and ready to bolt up) for motorcycle efi conversions, but ungodly expensive.
[21:22:05] <dirty_d> yea it is
[21:22:06] <zeeshan> when you're doing random welding
[21:22:14] -!- heathmanc1979 has quit [Quit: Leaving]
[21:22:16] <Cromaglious> mig is onehanded tig
[21:22:24] <zeeshan> i only use my tig in portable mode
[21:22:26] <zeeshan> when doing roll cages
[21:22:32] <zeeshan> but other than that ive really needed a mig for a long time
[21:22:37] <furrywolf> ... mig is not onehanded tig. they're completely different processes.
[21:22:47] <dirty_d> if you do a lot of welding mig is good
[21:22:54] <MrFluffy> have both, and tig every time for me...
[21:22:57] <zeeshan> dirty_d: give you a prime example
[21:23:00] <zeeshan> im working on my lathe enclosure
[21:23:02] <Cromaglious> furry I know...
[21:23:09] <MrFluffy> mig welding aluminum is like living on the knife edge of a disaster permanently...
[21:23:12] <zeeshan> i was trying to tig it.. it's a pain in the ass man
[21:23:22] <zeeshan> especially for tacking and trying to weld in a weird spot
[21:23:31] <dirty_d> yea it is harder
[21:23:41] <zeeshan> and its really not needed to be honest
[21:23:46] <zeeshan> for car stuff ill always use tig
[21:23:49] <furrywolf> mig is great for welding steel. for alu and stainless, use tig. mig is very fast and easy.
[21:23:51] <Cromaglious> yeah you really need the high Frequency component
[21:23:54] <zeeshan> but i wanted a mig to tack exhaust stuff
[21:23:55] <dirty_d> i just like the precision of tig
[21:24:12] <dirty_d> i dont mind if its harder and slower, because i dont relly have to weld much
[21:24:20] <zeeshan> the reason i started off with a tig is cause its a clean process
[21:24:28] <zeeshan> and most car people want their stuff tig'ed
[21:24:34] <zeeshan> cause you have a lot of control over penetration
[21:24:38] <dirty_d> yea
[21:24:41] <zeeshan> where with mig if it's not set right its more like
[21:24:43] <zeeshan> "spray and pray"
[21:24:46] <dirty_d> right
[21:25:00] <MrFluffy> a bad mig weld still looks good, thats what i dont like the most...
[21:25:04] <zeeshan> but i hate doing tig anywhere other than on the table
[21:25:06] <MrFluffy> until you break test it
[21:25:13] <dirty_d> ive seen good looking mig welds peel right off
[21:25:28] <dirty_d> i like that you can see exactly whats going on with tig
[21:25:34] <zeeshan> also another thing about mig.. its not as picky on dirty steel
[21:25:50] <dirty_d> i just use 6011 for dirty stuff
[21:25:53] <zeeshan> where you dont really need the strength , but just want to hold stuff
[21:26:07] <furrywolf> http://www.ecotrons.com/products/400cc_to_800cc_engine_fuel_injection_kit/ you can give them money and have efi-in-a-box...

[21:27:50] <MrFluffy> best bit of tig, picking up some unknown metal, bandsawing a strip off, and using that as the filler rod knowing it will match the composition...
[21:27:58] <dirty_d> if you like molten metal down your shirt

[21:33:15] <zeeshan> i can get em to 1/2 that width
[21:33:16] <dirty_d> i bought one of the chinese ones, then it stopped working
[21:33:34] <dirty_d> the gas valve still works though, so i got that going for me which is nice
[21:33:39] <furrywolf> MrFluffy: don't most of them lack sufficient hf to do aluminum?
[21:33:42] <MrFluffy> I blew my chinese set up, but a outfit in the uk repairs the boards, and it only cost $30 to fix
[21:34:17] <MrFluffy> my go to tig set is a 3 phase 400amp watercooled job, and that is chinese inside, its a welbach which is supposed to be german, but its shengzen all the way inside
[21:34:24] <MrFluffy> and that is lovely to use
[21:35:00] <MrFluffy> pretty much theyre all chinese now, even the names, all that happens is the manufacturers who care put their own QC into the lines to make sure everyone stays honest on component choice

[21:36:26] <zeeshan> yea well that doesnt make all of them made in italy
[21:36:45] <MrFluffy> Both lincoln and miller have chinese assembly plants
[21:36:58] <furrywolf> I didn't say all. I said "much".
[21:37:00] <zeeshan> ill take either one of those brands
[21:37:03] <zeeshan> that have their own qc here
[21:37:08] <zeeshan> vs a crappy import
[21:37:20] <zeeshan> ie POWERFIST!!!
[21:37:21] <Cromaglious> it was a marginal part to start with only 3v head room and it was a 5amp rated scr with a working load of 4.3aaaamps
[21:37:24] <MrFluffy> so would I but I cant afford to pay miller new prices...
[21:37:29] <zeeshan> me either
[21:37:32] <zeeshan> miller is so damn expensive
[21:37:38] <zeeshan> the dynasty 180dx is like 4k
[21:37:55] <zeeshan> my tig that i could from lincoln was like 1500 cheaper than that
[21:38:11] <zeeshan> it paid for itself within the first year i got it
[21:38:12] <Cromaglious> replaced it with a 30v 15amp scr
[21:38:19] <MrFluffy> I paid $1000 for the 400amp weibach, and its now 3 years old

[21:40:27] <MrFluffy> I still use it for heavy arc work, its superb for that still
[21:41:28] <MrFluffy> the welds come to me, i dont do that fieldwork stuff :)
[21:42:18] <MrFluffy> out of mig, tig and arc, i would take the tig and arc any day

[21:42:51] <MrFluffy> i dont have oxy acet anymore, but when i did it was handy to have around wiht a pepperpot torch to warm up things and other stuff, but the cylinder rental is stupidly expensive now
[21:42:58] <furrywolf> the snap-on is by far the lowest quality of them all. it makes harbor freight look good.

[21:44:54] <furrywolf> it uses a WINDSHIELD WIPER MOTOR to feed the wire! no electronics, speed control is just a rheostat. power selection is transformer taps. transformer and heavy wiring are all aluminum. it uses little button diodes, like found in a $5 battery charger, instead of proper welder-grade rectifiers.

[22:01:10] <furrywolf> I don't remember. straight dc, no fancy square wave duty cycle controls?
[22:01:42] <MrFluffy> you pay a bit more, you get ac
[22:01:53] <MrFluffy> theres a range, the more you go up, the more facilities you get
[22:02:22] <furrywolf> right, now say you have a budget of $100, what do you get?
[22:03:06] <MrFluffy> I know someone who just bought a ac set with all the bells on non working for $100 and its cost him $60 to get a new board for it from shopriver on ebay who will help you out if she sells the same units
[22:04:04] <MrFluffy> i have a chinese plasma cutter, and it blew up, the magic plasma smoke leaked out inside and it melted a hole through what used to be the lower power pcb, and a company in the uk sold me a new board for $30
[22:04:25] <MrFluffy> and i dont blame it, at the time i had no workshop, so it had been left in a storage room with a damp dirt floor
[22:04:45] <MrFluffy> theyre almost all the same inside rebadged...

[22:05:19] <MrFluffy> they all come out the same plant, then companies in the export zone buy them in, then resell them with their brands on, same deal as the Longs steppers
[22:05:35] <furrywolf> I have a Marquette (made by lincoln, in italy) plasma cutter... no brains, just a big transformer.
[22:06:37] <furrywolf> I've never tested it... got it cheap at a yard sale. needs all new consumables, possibly a new gun. it melted enough that I don't know if new consumables will make it work.
[22:07:35] <MrFluffy> if its just a transformer, put the meter on it and check the windings, then adapt one of the generic torches to it, or use it as a plasma table source
[22:07:56] <furrywolf> I can tell you it was putting out plenty of power when it stopped being used. :P
[22:08:38] <furrywolf> it looks like they tried putting a harbor freight nozzle on it (even came with a pack of them, with the other 4 of the 5 still in it), and it didn't work, melting everything behind it.
[22:09:30] <MrFluffy> On my spindle problem Im reading this,
http://linuxcnc.org/docs/html/examples/spindle.html , Im guessing my board means I have to do the first option in .hal...
[22:10:01] <MrFluffy> Maybe theres something wrong then, the air blast is supposed to protect the torch from the plasma heat

[22:11:00] <MrFluffy> DAC = PFM I am guessing
[22:12:09] <furrywolf> http://www.usaweld.com/Marquette-Plasma-Cutting-Parts-p/marquette5152-parts.htm needs all of them except the very outer nozzle holder, plus one part inside that I'm not sure is replacable... might need a new one turned from phenolic or something.
[22:12:48] <pcw_home> The difference is that you will need to use a stepgen component instead of a
[22:12:50] <pcw_home> PWM component to generate the signal your daughterboard needs
[22:13:04] <furrywolf> the diffuser sits in a round tube of what looks like phenolic, that's melted.
[22:15:21] <furrywolf> I tried ordering parts at the local lincoln dealer, and they said they weren't allowed to order marquette parts, even though it's a lincoln brand. yay corporations.
[22:15:22] -!- finnpixel has quit [Quit: KVIrc 4.2.0 Equilibrium http://www.kvirc.net/]
[22:15:26] <MrFluffy> Ok, so its not a DAC, as the pin is digital, so what would the equivalent signal be for spindle-speed-DAC ? I am still confused sorry.
[22:16:04] <MrFluffy> Its none of the examples on the spindle speed control wiki page I am guessing, but another way.
[22:16:11] <pcw_home> spindle-speed-dac is fine (its just a signal name you can make up any you like)
[22:16:36] <furrywolf> hrmm, some snap-on torch parts look suspiciously similar... did snapon rebrand marquette at some point?
[22:16:45] <MrFluffy> I tried and got the error :- bridgeport_interact1.hal:29: Signal 'spindle-speed-DAC' of type 'float' cannot add pin 'parport.1.pin-16-out' of type 'bit'
[22:17:02] <pcw_home> blue-wire-that-goes-to-the-spinny-thing will work just as well
[22:17:06] <MrFluffy> So I read that as am defining it as a float somewhere as its a analog signal?
[22:17:25] <furrywolf> http://ep.yimg.com/ay/weldingdirect/snap-on-plasma230-ya5550a-plasma-consumable-parts-4.gif on mine, the large tube sticking out of the torch head, grey colored in that image, is melted.
[22:18:22] <MrFluffy> furrywolf: I had that go on mine in use, and had to replace the head. When the tip fails it sometimes lets the plasma come out sideways as it goes and the heat goes back into the head damaging it.
[22:18:30] <pcw_home> yes you cannot connect pins of different tyops
[22:18:40] <pcw_home> types even
[22:18:50] <furrywolf> http://www.usaweld.com/v/vspfiles/photos/Marquette5152-Parts-2.jpg http://ep.yimg.com/ay/weldingdirect/snap-on-plasma230-ya5550a-plasma-consumable-parts-4.gif do those look like the same consumables to anyone but me?
[22:19:50] <MrFluffy> Ok that makes sense, Im trying to see where I actually cast the type of signal, I am editing the .hal in vi because stepconf is broken for me
[22:20:20] <pcw_home> so motion.spindle-speed-out --> stepgen velocity command
[22:20:22] <pcw_home> and stepgen step pin --> parport output
[22:20:24] <MrFluffy> I have the spindle on the second parallel port and its not triggering the spindle speed menu as a result, i posted a thread to the forum about it
[22:21:45] <pcw_home> dont think stepconf can build rate controlled DAC bolierplate anyway so you will need to add this to the hal file yourself
[22:21:49] <MrFluffy> To take that example, I have this, from the example:-
[22:21:50] <MrFluffy> net spindle-speed-scale motion.spindle-speed-out => scale.0.in
[22:21:52] -!- The_Ball [The_Ball!~ballen@220-244-24-84.static.tpgi.com.au] has joined #linuxcnc
[22:22:02] <MrFluffy> then :- net spindle-speed-DAC scale.0.out => parport.1.pin-16-out
[22:22:15] <pcw_home> you probably dont need scale
[22:22:22] <MrFluffy> the example is scaled so I copied that
[22:22:30] <MrFluffy> ok, less is more when something doesnt work
[22:22:35] <pcw_home> nor can you connect a float to a bit
[22:23:02] <pcw_home> first step is add new stepgen for spindle
[22:23:20] <pcw_home> next set said stepgen into velocity mode
[22:23:56] <pcw_home> then net motion.spindle-speed-out to the new stepgens velocity command input
[22:25:03] <furrywolf> hah, yep, found a page listing both those as cross-reference to the same part. so now I know how to find generic ones instead of stupidly overpriced ones.
[22:25:14] <pcw_home> (and set an appropriate stepgen scale for scaling)
[22:25:15] <pcw_home> finally net the step utput of the spindle stepgen to the parallel port pin of choice
[22:25:27] <pcw_home> step output
[22:26:44] <pcw_home> for actual pin names:
[22:26:46] <pcw_home> man motion
[22:26:46] <furrywolf> ... seriously? complete chinese plasma torches are only $10? that's cheaper than any one consumable for mine.
[22:26:47] <pcw_home> man stepgen
[22:27:13] <MrFluffy> So the stepgen is in quadrature velocity mode, aka type2 (I am reading that man page right now )
[22:27:18] <furrywolf> maybe I should just get one of those, then I can use harbor freight consumables.
[22:27:53] <pcw_home> yes that probably the best (close to square wave output)
[22:27:54] -!- per_sonne_ has quit [Ping timeout: 256 seconds]
[22:28:36] <pcw_home> though you should check your daughtercard specs (maybe it likes a fixed pulse width)
[22:29:01] <MrFluffy> ok, I think that means this (I have four axis already):- loadrt stepgen step_type=0,0,0,0,2 ctrl_type=p,p,p,p,v
[22:29:09] <MrFluffy> so the spindle will be the fifth
[22:29:26] <pcw_home> yeah something like that
[22:29:48] <MrFluffy> the card is aimed at mach, so it has some nice screenshots of the configs for that and not much more I am afraid
[22:30:11] <pcw_home> well you get to experiment :-)
[22:30:33] <MrFluffy> more importantly I get to understand the whys for what comes later...
[22:30:47] <pcw_home> does it specify the frequencies for 0 and 10V?
[22:31:04] -!- skorasaurus has quit [Ping timeout: 252 seconds]
[22:31:57] <furrywolf> my mach-oriented breakout board says pwm, not pfm...
[22:32:02] <MrFluffy> Yes, 10 volts output for 2000 pulses per second
[22:32:39] <MrFluffy> this is stepper, they say to connect it as the A axis steppers
[22:32:59] <MrFluffy> 10v into the altivar = 2000rpm, so i need 2000 pulses per second to get top speed out the spindle
[22:33:17] <MrFluffy> That seems quite high on first reflection...
[22:34:25] <MrFluffy> From the book, Mach3 Typical Spindle setup Note: Step/dir Motor checked and Use Motor Output.
[22:35:23] <MrFluffy> Compared to the chinese bob I was going to use, this actually has instructions which is a plus, I just didnt understand the concept enough to use the information.
[22:36:23] <pcw_home> if 2000 RPM is full speed you need to scale the stepgen in Hz so stepgen.N.position-scale = 1
[22:38:30] <MrFluffy> so I would use stepgen.5.phase-A output for the pin signal?
[22:38:51] <pcw_home> ( so when motion.spindle-speed-out = 2000, the stepgen generates 2000 steps per second )
[22:38:53] <pcw_home> Yes ( or B )
[22:39:51] <pcw_home> (the stepgens built in scaling is why the scale comp is not needed)

[23:09:41] <MrFluffy> would it need a addf first, but the pin is a binary not a float isnt it...

[23:24:20] <andypugh> MrFluffy: You need a “loadrt scale” somewhere or scale.0… won’t exist. It also won’t exist if your loadet scale uses the names= option (the scale wil be called something other than scale.0)
[23:39:41] <pcw_home> (and you dont need scale at all since the stepgen is scalable)
[23:42:00] <andypugh> That too. Even if the input it rps and you want rpm, then you can fudge that by scaling the stepgen suitably.
[23:42:16] <MrFluffy> I think I have found the culprit, I have added more config into custom.hal and custom_postgui that is interfering, right now its loading, so I have to go out into the shop to see if its actually going round as Im sshd in from the house
