[04:29:12] <archivist_herron> bookmark
[05:01:14] <Mjolinor> I'm looking for a front end for linuxcnc for a coil winder. It needs to display how many turns, the machine will jsut be 2 steppers, one rotating the core adn one moving the wire along
[05:01:36] <Mjolinor> I am sure soemone must have done it already to give me a starting point, anyone got any links or seen one?
[05:04:32] <archivist_herron> there have been at least one if not two
[05:05:03] <Mjolinor> I thought there would be but Im buggered if I can find them
[05:05:21] <Mjolinor> its not hte machine I need input on, it is jsut the fornt end for linuxcnc
[05:05:27] <Mjolinor> its not hte machine I need input on, it is jsut the front end for linuxcnc
[05:05:42] <Mjolinor> my typing is pretty damn bad today :)
[05:34:37] <jthornton> Mjolinor,
http://www.gnipsel.com/linuxcnc/index.html
[05:43:24] <Loetmichel> jthornton: did you experiment with a servo drive that is fully controlled by LinuxCNC and LPT?
[05:43:30] <Mjolinor> cheers
[05:43:34] <Loetmichel> i wonder if that can work
[05:44:27] <Loetmichel> i.e: a cheap L298 or such as amplifier, encoders directly to LinuxCNC and let linuxCNC put out a PWM wirt 50% as "stoodstill"
[05:44:46] <Loetmichel> i.e: a cheap L298 or such as amplifier, encoders diri hacvve 18 small DC servos hereectly to LinuxCNC and let linuxCNC put out a PWM wirt 50% as "stoodstill"
[05:44:50] <Loetmichel> grrr
[05:45:07] <Loetmichel> i have 18 cheap sdc servos here
[05:45:22] <Loetmichel> that would make good drives for small routers, but no means of driving them
[05:45:31] <jthornton> Loetmichel, no my servo machines all use Mesa cards
[05:45:50] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13519
[05:46:23] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13248 <- are surplus fro a little "company cleanup"
[05:46:50] <Loetmichel> hmm, mesa card is a bit expensive for that servo
[05:49:25] <Loetmichel> these servos are 24V 2A 100cpr
[05:49:43] <Loetmichel> neats stuff inside these printers ;-)-s
[05:50:46] <jthornton> sounds like a good find
[05:54:52] <micges> Loetmichel: it's will work
[05:55:05] <micges> s/it's/it
[05:58:07] <micges> you will probably have headache setting up PID or probably two PIDs cascade
[06:00:39] <archivist_herron> Loetmichel, look at

[07:22:29] <Tom_itx> http://www.linuxcnc.org/emc2/index.php/english/forum/38-general-linuxcnc-questions/25829-winding-transformer-coils-lathe-mode
[07:25:44] <L84Supper2> Loetmichel: dirt cheap servos like that here in China, I've been finding servos and steppers at ~30% of the prices on alibaba and taobao
[07:26:39] <Tom_itx> so they're making a 30% profit?
[07:27:43] <micges> L84Supper2: will those servos works for more than 2 months?
[07:27:54] <ReadError> Tom_itx: more than 30 i would guess
[07:28:15] <ReadError> if they sell for $100 on alibaba, and they cost $30
[08:08:44] <Mjolinor> I have version 10.04 ubuntu with EMC/axis version 2.5.0-pre2-626g402b6cd. Normally I dont have internet on the PC with emc, it all works well and has done for soem time. As I intending to reconfigure to allow my to make a front end following jthornton tutorial should I let it all upgrade?
[08:08:59] <L84Supper2> it looks like ~60% profit
[08:09:06] <Mjolinor> the ubuntu update manager wants to stick 12.04 LTS in there
[08:09:13] <L84Supper2> sorry, 200%
[08:09:36] <eric_unterhausen> 200% markup
[08:09:46] <L84Supper2> yeah
[08:09:47] <Mjolinor> very concerned that it will break. I stopped using ubuntu completely when they started with that new front end thing, cant remmber the name
[08:10:02] <Mjolinor> unity, thats it, does this 12.04 have unity?
[08:10:09] <eric_unterhausen> ubuntu upgrades fairly well
[08:10:14] <eric_unterhausen> yes it has unity
[08:10:23] <Mjolinor> groan
[08:10:26] <Mjolinor> :)
[08:10:28] <eric_unterhausen> I got used to it
[08:10:30] <L84Supper2> paid <$2 for couplings yesterday I see for $6 online
[08:11:04] <Mjolinor> I couldnt get used to it so I moved over to Mint, love that
[08:11:19] <L84Supper2> and that's paying the foreigner price
[08:11:21] <Mjolinor> but I dont want to break my EMC machine
[08:11:27] <Mjolinor> linuxcnc machine
[08:11:49] <eric_unterhausen> there are ways to avoid unity on ubuntu
[08:12:37] <Mjolinor> I know but it got harder adn harder to do with each release so I just gave up with it
[08:13:06] <eric_unterhausen> if I run out of space on the menu bar, then it could be a problem
[08:13:27] <L84Supper2> I wouldn't build my submicron accuracy micro-mill with this stuff, but it's fine for CNC routers and CNC glue guns
[08:14:06] <Mjolinor> are there many changes from 2.5.0 to 2.5.2?
[08:14:13] <L84Supper2> aerotech and similar suppliers have nothing to worry about
[08:14:32] <eric_unterhausen> aerotech is feeding the beast over there
[08:14:47] <eric_unterhausen> I'm guessing they should worry long-term
[08:15:03] <jthornton> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Released_2.5.X
[08:15:29] <Mjolinor> reading the changelog now, there doesn't seem to be much that willprevent me sticking with 2.5.0
[08:15:56] <Mjolinor> think maybe I should change my hard disk and do a new install perhaps that would be best bet
[08:17:01] <L84Supper2> from what I've seen Keling makes about 1-2x on most parts, one of the down side seems to be QC and how many bad parts are mixed in with the good ones
[08:20:22] <jdh> keling doesn't seem to be any more expensive than any other single-quantity places I've seen online (ali* included)
[08:20:27] <L84Supper2> where to find quality hand tools is still a mystery here, Stanley is the top of the line at many markets :)
[08:22:06] <Mjolinor> ok, confused now. THe download is still Ubuntu 10.04. Does this have 2.5.2 in or an earlier one?
[08:22:17] <L84Supper2> lots of Bosch power tools
[08:22:21] <eric_unterhausen> d/l hasn't changed
[08:22:25] <Mjolinor> ok
[08:22:34] <Mjolinor> cheers, Ill stick with what I have :)
[08:22:35] <eric_unterhausen> you always have to upgrade linuxcnc
[08:23:32] <Mjolinor> sad when it all works so well, must be 2 years since I looked at installing as it all works perfectly so I have forgotten what I did
[08:39:10] <FinboySlick> Mjolinor: Newest versions of ubuntu are getting pretty bloated, 10.04 is not something I mind one bit :)
[08:40:01] <Mjolinor> I dont mind 10.04 and would stick with it if it were OK
[08:40:24] <Mjolinor> depends whether linuxcnc has moved forward since last time I looked, it seems it hasn't so 10.04 will stay :)
[08:47:26] <ssi> I have some 13.x boxes, and they're horrible :P
[09:03:38] <DJ9DJ> re
[12:15:56] <IchGuckLive> Hi all B)
[13:17:45] <IchGuckLive> lots of posts today O.o
[13:28:08] <IchGuckLive> im of for today By
[14:25:33] <andypugh> I may be about to do a strange thing. I am going to convert a motor from encoder to resolver.
[14:26:13] <archivist> we wont laugh too much
[14:26:35] <Jymmm> We won't? Oh, yeah, we won't.
[14:27:43] <Jymmm> andypugh: Can't be any stranger than JT-Shop making industrial grade sex toys.
[14:28:41] <andypugh> There is something slightly funny about it, there is a spigot in the middle of the stationary part, right where you would expect the motor shaft to be. Anyone seen that arrangment before and know how it all goes together?
http://www.ebay.co.uk/itm/261214253903
[14:29:03] <andypugh> I would hazard a guess that it is EM shielding.
[14:29:55] <andypugh> I wonder which is motor-side and which out-side?
[14:30:29] <andypugh> Curiously it had abot a gazillion extra wires all not going anywhere, I suspect there was on-board conversion to digital originally.
[14:30:48] <andypugh> But it definitly is a two-pole resolver, and works nicely.
[14:32:06] <archivist> I have never played with one yet
[14:33:32] <cradek> I wonder if Elson ever did anything with the one I gave him
[14:33:40] <cradek> it was like 10" diameter
[14:33:50] <cradek> had many many poles
[14:34:09] <andypugh> I want one like that for my lathe. In fact I am thinking of making one like that for my lathe.
[14:34:41] <cradek> I gave it to him because his resolver converter couldn't drive it - not enough current or something
[14:35:09] <cradek> he might be interested in passing it on to you if he hasn't messed with it yet
[14:35:26] <andypugh> That one I have appears to have lots of poles, but in practice it doesn't, it is a 2 pole.
[14:36:12] <andypugh> Which leads me to believe that I don't actually know how they work.
[14:36:16] <cradek> haha
[14:37:30] <archivist> I thought the many apparent slots are really magnetic averaging
[14:37:44] <cradek> http://timeguy.com/resolver-colorcodes.jpg
[14:37:52] <andypugh> I know there is a complete circular winding that provides power to the primary. But the primary appears to have many poles, and the secondary has a different many.
[14:38:00] <cradek> I guess this is the only picture I have of it - the outside of the casing
[14:39:04] <andypugh> A common centre tap for the secondaries is most odd.
[14:39:40] <archivist> star instead of delta ?
[14:40:13] <archivist> I could go get a book and read up :
[14:40:17] <andypugh> They are a 2-phase device.
[14:42:23] <cradek> oh wow I found it:
http://timeguy.com/cradek-files/emc/PICT6447.JPG
[14:42:28] <andypugh> Having said that, my Arduino-based convertor connects 2 secondary wires together:
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?ResolverToQuadratureConverter
[14:43:01] <cradek> I think I tried isolating those two with 1:1 audio transformers
[14:43:50] <andypugh> That appears to be a completely passive rotor.
[14:43:54] <cradek> yes it is
[14:44:17] <cradek> I think elson called it a variable reluctance resolver
[14:44:20] <andypugh> Interesting...
[14:46:00] <cradek> I think each tooth on the rotor caused its own pole
[14:46:14] <cradek> I was tempted to try thresholding it and using it as quadrature, there were so many
[14:47:17] <andypugh> It looks ideal for a lathe spindle, the centre-hole diameter looks very ample.
[14:47:46] <andypugh> Are you using the motor?
[14:48:11] <cradek> the motor under that rotor is my mill spindle
[14:48:35] <cradek> that rotor was pulled off and given along with the cap on the right to elson a few years ago
[14:48:42] <andypugh> Do you have spindle feedback at the moment?
[14:48:56] <cradek> yes I stuck an encoder where this used to be
[14:49:23] <andypugh> Ah, because that rotor would be a perfect target for those gear-sensors (like Jon used on his BP)
[14:50:13] <cradek> true that would be neat
[14:50:34] <cradek> one of us could ask him to bring it in June, if you want it
[14:51:34] <cradek> hm, not sure how you'd get index
[14:51:43] <GammaX-Shop> hey guys
[14:51:49] <andypugh> drill a hole in something.
[14:51:56] <GammaX-Shop> anyone use the shars fly cutters before with hss insert?
[14:52:32] <Tom_itx> could you compare a resolver to an electrical harmonic drive?
[14:52:44] <Tom_itx> in reverse
[14:53:11] <andypugh> There isn't any "vernier" action.
[14:53:34] <andypugh> GammaX-Shop: HSS _insert_?
[14:54:05] <GammaX-Shop> andypugh: yeah all the adds im seeing come with a "HSS square tool bits"
[14:54:08] <JT-Shop> high speed steel
[14:54:24] <andypugh> Ah, yes, toolbit.
[14:54:33] <cradek> there are definitely a few hss inserts available
[14:54:39] <Tom_itx> few
[14:54:41] <andypugh> "Insert" normally suggests carbide.
[14:55:01] <Tom_itx> or compressed powder or ceramic
[14:55:02] <cradek> but for a fly cutter just grind a square hss on your bench grinder
[14:55:05] <GammaX-Shop> interesting...
[14:55:45] <andypugh> I ought to use HSS more. It's perfectly adequate for anything non-production, and you can choose your own geometry.
[14:55:48] <GammaX-Shop> cradek, how long would one of those bits last before needing resharpening or.. "re edging"?
[14:56:03] <cradek> if cutting butter, years
[14:56:29] <cradek> sorry, that's my smartass way of saying it matters what you're doing with it
[14:56:57] <GammaX-Shop> lol
[14:57:02] <GammaX-Shop> mainly alum
[14:57:02] <Tom_itx> http://deltamotion.com/support/webhelp/rmctools/Controller_Features/Transducer_Basics/Resolver_Fundamentals.htm
[14:57:07] <GammaX-Shop> Im thinkin about getting this
http://www.shars.com/products/view/8111/5_Piece_Fly_Cutter_Set
[14:57:12] <andypugh> I think that HSS will last as long as anyone using a flycutter would need.
[14:58:05] <andypugh> (On the basis that flycutters are typically hobbyist use)
[14:58:18] <Tom_itx> or manual mills
[14:58:32] <Tom_itx> we'd use a flycutter on the manual over a shell mill
[14:58:49] <cradek> that's about 3 more flycutters than you'd ever need
[14:58:54] <Tom_itx> yup
[14:59:06] <cradek> the teeeeny shank on the big one makes it pretty silly
[14:59:08] <andypugh> If you want properly flat then single-pointing has a lot going for it.
[14:59:15] <Tom_itx> if you need one, you're planning on cutting a fairly large flat surface
[14:59:26] <GammaX-Shop> yeah but its the only shars that has a 1/2 bit
[14:59:27] <GammaX-Shop> 1/2 inch*
[14:59:30] <cradek> but you can pick the size that works the best for your machine
[14:59:47] <GammaX-Shop> Maby im better off getting a face mill..
[14:59:57] <Tom_itx> will cost more
[15:00:00] <andypugh> I would think that perhaps one good one would be better
[15:00:38] <cradek> they have an R8 shank one
[15:00:45] <cradek> what's your spindle taper?
[15:00:53] <GammaX-Shop> dont want r8.... have quick tool change
[15:01:09] <GammaX-Shop> would love 7/8ths but dont think thats gunna happen
[15:01:09] <cradek> what's quick tool change?
[15:01:24] <GammaX-Shop> just like a tormach
[15:01:29] <andypugh> http://www.tormach.com/store/index.php?app=ecom&ns=catshow&ref=flycutters
[15:02:07] <GammaX-Shop> andypugh: yeah I thought abot it but too rich for my blood. Dont wanna spend any money on tormach products to be honest...
[15:02:42] <cradek> you could get any old thing that matches your spindle and mill away the parts that aren't a fly cutter holder
[15:02:50] <andypugh> Tormach are fairly cheap compared to Sandvik / Nikken etc
[15:03:02] <GammaX-Shop> http://www.ebay.com/itm/KENNAMETAL-2-NO-KL21R-INDEXABLE-FACEMILL-W-3-4-SHANK-/111080114155?pt=LH_DefaultDomain_0&hash=item19dce407eb
[15:03:50] <cradek> I doubt you have the spindle to push that thing
[15:03:54] <andypugh> I have a 4" R8 flycutter on the floor behind me (note to self, shift it before the dent in the carpet is permanent)
[15:04:21] <cradek> and it'll gum up horribly on aluminum
[15:04:27] <cradek> those inserts are totally wrong
[15:04:44] <andypugh> For $1.50 I would find out if I had the spindle. I had no problems with a 2.5" on my mini-mill.
[15:04:44] <cradek> you'll really do much better with a hand-ground hss blank
[15:05:24] <cradek> ah sure if it's that cheap, why not try it
[15:05:30] <andypugh> But I agree with cradek.
[15:05:49] <GammaX-Shop> I got 3hp on belt drive.
[15:05:54] <cradek> but yeah, you won't end up having it as your favorite and most useful tool :-)
[15:06:00] <GammaX-Shop> lol
[15:06:26] <GammaX-Shop> 3hp with straight 3 phase
[15:06:36] <andypugh> My mill has a lowest-ratio of 47 rpm. I hate to think what size cutter they had in mind there
[15:06:55] <cradek> is it pre-hss?
[15:07:18] <cradek> they used to cut soooo slowly
[15:08:07] <GammaX-Shop> well then I should ask you guys... for semi production work... maby 10-20 parts of each.... mainly aluminum... what would you guys use?
[15:08:27] <archivist> carbon steel cutters and chewing cast iron
[15:08:54] <archivist> hss
[15:09:14] <GammaX-Shop> fly cutter / face mill ?
[15:09:29] <archivist> depends
[15:09:40] <archivist> there is no one answer
[15:09:42] <cradek> GammaX-Shop: at 3hp I'd use a 3/4" 3 flute roughing mill for everything possible
[15:09:52] <andypugh> cradek: No, it was built in about 1975.
[15:10:21] <cradek> for 10-20 parts you can sometimes avoid facing stuff just by buying the right size material
[15:10:35] <cradek> the quickest way to do work is to avoid it
[15:10:44] <GammaX-Shop> cradek: but sometimes I will b making 1 offs....
[15:10:47] <GammaX-Shop> lol
[15:11:12] <archivist> even at one off have the right size hanging around
[15:11:40] <archivist> be lazy and go to a local cnc material supplier and get cut to size
[15:12:14] <archivist> I just did a fabrication job that way
[15:12:15] <GammaX-Shop> well first job coming up is adapter plates for throtle bodies.
[15:12:33] <GammaX-Shop> so its gotta be as flat as possible lol
[15:12:56] <archivist> you can buy ground flat aluminium
[15:13:16] <GammaX-Shop> yes but thats $$$
[15:13:28] <GammaX-Shop> when I can buy either a facemill or fly cutter and go to town on it real quick...
[15:13:44] <GammaX-Shop> rather do the work myself and learn from it instead of having another company do it...
[15:13:52] <archivist> flattening is slower
[15:14:26] <archivist> you get to cut the holes and outer profile
[15:14:41] <cradek> these are just awesome:
http://www.ebay.com/itm/350735478182
[15:15:22] <GammaX-Shop> regardless... i need a fly cutter or face mill lol
[15:15:33] <GammaX-Shop> cradek: I got a crap load of rouging end mills...
[15:16:01] <cradek> use mic-6 if you want a gasket to work on it as-is...
[15:16:24] <archivist> remember a face mill on a crap machine will produce a concave form
[15:17:12] <cradek> maybe you get to buy a surface grinder
[15:17:19] <archivist> or saw tooth as we had once
[15:18:33] <archivist> you get a better flat with smaller tooling on a poor machine
[15:18:41] <GammaX-Shop> lol fine fine
[15:18:49] <GammaX-Shop> shars fly cutter it is!
[15:19:33] <archivist> I had a crap chinese mill that came with a face cutter, I learned the hard way
[15:19:51] <JT-Shop> it does depend on the wear on the X axis if you get flat or a copy of the wear
[15:19:54] <cradek> it's hard to machine flat on anything
[15:20:51] <archivist> one of these
http://www.ebay.co.uk/itm/1979-Alpine-Complex-Drilling-Milling-Machine-Model-DM25-bench-top-240v-/360663746250?pt=LH_DefaultDomain_3&hash=item53f93c06ca
[15:21:50] <archivist> I got lucky and managed to sell it
[15:31:38] <andypugh> This motor that I want to convert to resolver (anyone want a 17-bit absolute encoder that may or may not work, with the right hardware?)
[15:32:51] <andypugh> I am thinking about being even more stupid and removing the brake. That will probably involve re-machining the motor shaft (no point removing the brake and leaving the motor overlength)
[15:33:05] <andypugh> I wonder how likely that is to end in tears?
[15:33:21] * JT-Shop thinks andypugh is having too much fun
[15:33:55] <archivist> if this is the spindle motor, why not keep the brake to lock it while using live tooling
[15:34:31] <andypugh> No, this is a little 630W servo (NEMA34). Looks like a really good X-axis motor for a lathe.
[15:47:06] <Tom_itx> using unfinished material is fine unless there's a finish callout on the blueprint
[16:03:45] <GammaX-Shop> anyone care to comment on size bit for the fly cutter if thats the route I go?
[16:04:34] <toastydeath> biggest you can reasonably afford to replace
[16:04:43] <toastydeath> what size machine
[16:04:55] <GammaX-Shop> 3hp belt drive
[16:05:00] <toastydeath> knee mill?
[16:05:07] <GammaX-Shop> square column
[16:05:12] <Tom_itx> 3"
[16:05:24] <toastydeath> do you have a link to the machine you have
[16:05:38] <GammaX-Shop> knee mill is coming hopefully within the year. Back in the day I had a supermax but my father through it out while I was in afghanista..... wtf is up with that! lol
[16:05:49] <GammaX-Shop> toastydeath: just an rf45 clone with modifications.
[16:06:07] <toastydeath> hm
[16:06:22] <Tom_itx> 3" would be about right i'd think
[16:06:38] <toastydeath> "bit size" on a flycutter generally refers to the type of lathe bit it holds
[16:06:45] <GammaX-Shop> well I meant more of... 5/16 1/2?
[16:06:47] <toastydeath> do you mean diameter or bit size
[16:07:16] <GammaX-Shop> I gotta learn to give more attention to detail on how I word things via chat casue I cant physicly show you what im reffering too haha.
[16:07:34] <toastydeath> generally I'd go with the largest bit your flycutter will hold.
[16:07:46] <Tom_itx> less chatter that way
[16:07:57] <toastydeath> you can overhang the bit more when necessary with less trouble
[16:08:39] <GammaX-Shop> well I need to find a fly cutter that is appropriate for my machine and theres many designs with diff bit sizes....
[16:08:43] <GammaX-Shop> thats where im stuck!
[16:09:35] <toastydeath> the smaller the flycutter, the smaller the bit it will hold
[16:09:57] <GammaX-Shop> Im thinkin about the shars but Id really like to get a 7/8's shank...I can get by for not with a 3/4
[16:10:11] <toastydeath> what taper is the machine
[16:10:20] <toastydeath> r8
[16:10:21] <toastydeath> ?
[16:11:28] <archivist> GammaX-Shop, have yo done a flat area test to see how square the column is to xy planes
[16:12:04] <FinboySlick> archivist: Don't say things like that, you'll produce more people like me ;)
[16:12:04] <GammaX-Shop> r8 but I have a tormach style quick change tooling setup in it. I will be changing to custom er32 7/8ths shank soon...
[16:12:10] <toastydeath> having a flycutter with the spindle taper of your machine is a lot less dangerous than a loose flycutter
[16:12:15] <GammaX-Shop> archivist: just trammed it up.
[16:12:20] <archivist> FinboySlick, :)
[16:12:48] <GammaX-Shop> but not testing with material....
[16:13:32] <toastydeath> tormach makes a flycutter with the TTS taper
[16:13:34] <toastydeath> apparently
[16:13:46] <GammaX-Shop> yes but thats $$$
[16:13:50] <archivist> put the dti back in and lean on the column with little finger
[16:13:55] <GammaX-Shop> and I dont trust tormach too much... idk y
[16:14:32] <GammaX-Shop> archivist it will move about maby a thousanth
[16:14:48] <FinboySlick> GammaX-Shop: For what it's worth, I'd be a happier person if I had spent the same money on a tormach ;)
[16:15:17] <GammaX-Shop> FinboySlick: what u have now?
[16:16:03] <FinboySlick> GammaX-Shop: Syil X5 Speedmaster
[16:20:40] <FinboySlick> Well, maybe not that happy... It would probably have crashed straight through my floor.
[16:21:09] <DJ9DJ> gn8
[16:21:47] <GammaX-Shop> lol
[16:40:10] <Nick001-Shop> How do I copy a man command in terminal to a txt file?
[16:40:31] <GammaX-Shop> worth it??

[16:40:50] <GammaX-Shop> Nick001-Shop: what do you mean by copy a man command?
[16:41:27] <archivist> man blah > file.txt
[16:41:49] <GammaX-Shop> ohhh
[16:42:51] <GammaX-Shop> theres multiple ways
[16:42:58] <GammaX-Shop> IE man ls > ls.man
[16:43:07] <archivist> sez me rapidly trying it to see if it was that simple
[16:43:18] <GammaX-Shop> man lilo | col -bx >lilo.txt
[16:43:53] <GammaX-Shop> lol you literally had it rite when you wrote it haha
[16:44:27] <archivist> unix/linux has been like that for a "while"
[16:45:55] <Nick001-Shop> need a file to hold all the info with man hostmot 2 into a file for easier reading.
[16:48:29] <Nick001-Shop> and where does it put it? desktop?
[16:48:56] <archivist> where you what it
[16:49:02] <archivist> want
[16:49:34] <archivist> the version I gave is the current directory
[16:49:40] <GammaX-Shop> Nick001-Shop: where ever you executed that command
[16:49:40] <Nick001-Shop> do i specify it or is there a default dir
[16:50:12] <Nick001-Shop> executed in terminal
[16:50:16] <archivist> the default is where you are, else up to you
[16:50:18] <GammaX-Shop> you can specify if you put /home/BLAH/Desktop/BLAH.MAN
[16:51:19] <Nick001-Shop> ok - i'll try it again - computers are 60' apart - gotta chase
[16:51:57] <archivist> use wire in between
[16:52:05] <Tom_itx> tennisshoe net
[16:55:18] <Nick001-Shop> found them -seems the default folder is home - not desktop, have to remember that - thanks for the help
[17:07:14] <GammaX-Shop> lol
[17:09:37] <JT-Shop> seems rapid velocity of Z has no effect on when the drive trips out
[17:12:31] <GammaX-Shop> anyone recomend carbide tipped bits vs hss for fly cutter?
[17:13:26] <GammaX-Shop> I ordered 3/8ths ones
[17:14:15] <GammaX-Shop> well... I ordered this
http://www.ebay.com/itm/FLY-CUTTER-SET-CUTTERS-3-4-SHANK-METAL-FOR-BRIDGEPORT-/270348981272?pt=LH_DefaultDomain_0&hash=item3ef20e1418
[17:15:21] <andypugh> Isn't that mor expensive than Shars?
[17:15:46] <GammaX-Shop> that is shars
[17:15:50] <GammaX-Shop> free shipping
[17:16:27] <GammaX-Shop> less than on shars website
[17:16:45] <GammaX-Shop> and it holds 3/8ths bit vs 5/16th
[17:17:09] <GammaX-Shop> andypugh: what u think about type of bit?
[17:17:52] <andypugh> HSS.
[17:18:11] <andypugh> Tougher, cheaper, you can sharpen it to the ideal angle for the job.
[17:19:20] <GammaX-Shop> ahh and the tipped one you can... gotcha
[17:19:29] <andypugh> You can always add a left-handed lathe tool to your collection if you want to use carbide inserts.
[17:21:03] <GammaX-Shop> andypugh: gunna make any differance over hss realisticly?
[17:21:46] <andypugh> Unless you go into the injection moulding die business, I doubt it.
[17:22:05] <GammaX-Shop> lol nope
[17:22:13] <GammaX-Shop> just want a nice shiny finish on my shit
[17:25:11] <GammaX-Shop> think these will do nicely

[17:39:49] <andypugh> GammaX-Shop: Do you have a bench grinder?
[17:41:45] <GammaX-Shop> andypugh: yup
[17:42:36] <andypugh> There must be into on the interweb about grinding tools to the right geometry.
[17:46:15] <tjtr33> i thought this was stupid before, now kuka did it at Hannover

[17:51:29] <GammaX-Shop> jesus christ that looks dangerous! lol
[17:55:16] <DaViruz> i like the little extending docking platform
[18:00:24] <GammaX-Shop|2> anyone know how to find the angles of round edges? either inner or outer?
[18:01:00] <JT-Shop> how can round be an angle?
[18:01:19] <GammaX-Shop|2> im using the wrong terminology...
[18:01:25] <JT-Shop> ok
[18:01:40] <GammaX-Shop|2> got the term has slipped my mind...
[18:01:44] <GammaX-Shop|2> god*
[18:01:49] <GammaX-Shop|2> geometry?
[18:02:36] <JT-Shop> do you mean like the start angle, end angle, radius, center point?
[18:03:38] <GammaX-Shop|2> radius :)
[18:04:10] <GammaX-Shop|2> thanks JT-Shop
[18:04:15] <andypugh> With a radius gauge
[18:04:39] <JT-Shop> aye

[18:07:26] <GammaX-Shop|2> ahhhhh
[18:07:29] <JT-Shop> http://www.starrett.com/metrology/product-detail/Precision-Measuring-Tools/Precision-Hand-Tools/Fixed-Gage-Standards/Radius-Gages/S167AZ
[18:07:35] <JT-Shop> that's the one I have
[18:07:48] <GammaX-Shop|2> you got fancy stuff
[18:07:51] <JT-Shop> or maybe it is a bigger one
[18:08:50] <JT-Shop> it's just a radius gauge... depends on your eye to be accurate
[18:09:52] <GammaX-Shop|2> JT-Shop: starret be expensive... in my eyes fr now atleast lol
[18:10:39] <JT-Shop> aye you need to make money not buy things
[18:11:08] <GammaX-Shop|2> yup
[18:11:11] <andypugh> I just bought a Starret set from eBay. (well, I bid on it, at least)
[18:11:33] <andypugh> I can't believe that I have managed all these years without one :-)
[18:13:28] <JT-Shop> I can't even find mine
[18:13:52] <GammaX-Shop|2> lol
[18:14:01] <GammaX-Shop|2> 167c seems to be the way to go
[18:17:17] <JT-Shop> are you trying to reverse engineer a part?
[18:17:43] <GammaX-Shop|2> well in theory... but not so much
[18:17:48] <andypugh> probing might work best
[18:17:56] <JT-Shop> aye
[18:18:01] <GammaX-Shop|2> take a radius off a part to make flanges or adapt something to it.
[18:18:16] <JT-Shop> a probe is your friend
[18:20:03] <GammaX-Shop|2> well to start out with... I would rather be able to do it manually. than use a probe....
[18:20:13] <JT-Shop> why?
[18:20:20] <GammaX-Shop|2> and probes cost mroe which i dont need right now and it could in theory be more of a hassle for a 1 of part
[18:20:32] <JT-Shop> make one
[18:20:46] <GammaX-Shop|2> Ill pass on that one lol
[18:21:00] <JT-Shop> actually you could map out a part rather fast with probe
[18:21:09] <JT-Shop> they are simple to make
[18:23:15] <GammaX-Shop|2> well my lathe is down atm
[18:24:26] <GammaX-Shop|2> and last time I was around in 2008 there wasnt much support for the probing functions with lcnc
[18:25:10] <JT-Shop> describe "support"
[18:25:32] <GammaX-Shop|2> functionality?
[18:25:50] <GammaX-Shop|2> I think it was YOU that told me to stay away from them and learn it by hand first! haha
[18:25:57] <GammaX-Shop|2> BUT that was back when you were big....
[18:26:10] <JT-Shop> well I might have told you to learn g code by hand
[18:27:01] <JT-Shop> and now I'm just medium
[18:27:10] <GammaX-Shop|2> lol
[18:27:25] <GammaX-Shop|2> you ever get that trailer?
[18:27:29] <GammaX-Shop|2> from nc i think it was
[18:27:46] <JT-Shop> 1400 miles in 36hrs
[18:31:09] <Tom_itx> nice 2 day drive ehh?
[18:31:35] <GammaX-Shop|2> ouch
[18:31:58] <GammaX-Shop|2> andypugh: which one are you bidding on. I dont wanna steel your thing.
[18:32:18] <andypugh> I am in the UK, so fret not.
[18:32:21] <Tom_itx> GammaX-Shop|2, are you in the us?
[18:32:23] <Tom_itx> :)
[18:32:25] <GammaX-Shop|2> yessir
[18:32:32] <GammaX-Shop|2> andypugh: ahh nice nice
[18:33:01] <GammaX-Shop|2> for 41 bucks US I can get a 167c but without the holder...
[18:33:07] <GammaX-Shop|2> dunno how much id use that though...
[18:33:35] <Tom_itx> tornado tossing debri 1.25 mi in the air showing up on radar
[18:33:53] <JT-Shop> yikes
[18:33:56] <Tom_itx> andypugh, better bring your trench hat with you
[18:34:08] <Tom_itx> JT-Shop, up around the Topeka area
[18:34:39] <JT-Shop> I hate when they are in Van Buren... cause I'm next

[18:37:05] <GammaX-Shop|2> luckily im in denver, and previously... NY
[18:39:24] <andypugh> I am sure it will all have blown over by next month.
[18:39:44] <Tom_itx> it's the beginning of the season
[18:40:54] <GammaX-Shop|2> what do you guys think. this

[18:41:13] <GammaX-Shop|2> or a used starret 167c without the holder?
[18:41:28] <Tom_itx> starret or General are both decent
[18:41:42] <Tom_itx> dunno about that brand
[18:41:57] <Tom_itx> looks ok
[18:42:03] <GammaX-Shop|2> general?
[18:42:18] <Tom_itx> they also make measurement stuff
[18:42:41] <andypugh> Moore and Wright.
[18:43:06] <toastydeath> what do you need a radius gauge for
[18:43:22] <JT-Shop> he likes shiny things :)
[18:43:24] <GammaX-Shop|2> to be a boss
[18:44:01] <GammaX-Shop|2> and I dont wanna buy a damn probe for mad cash lol
[18:44:03] <Tom_itx> get a full set of gage blocks too
[18:44:07] <Tom_itx> round and square
[18:44:20] <Tom_itx> make sure they're certified
[18:44:24] <toastydeath> gage blocks are rly useful and with some patience and a DTI, can check radii
[18:44:35] <toastydeath> (plus your machine's spindle)

[18:46:59] <Tom_itx> i only have a couple gage blocks but the shop i was at had a full certified set of both
[18:47:09] <PCW> Wow that goes beyond just special
[18:47:14] <Tom_itx> i check my calipers & mics with em
[18:47:52] <GammaX-Shop|2> how many of you use a probe?
[18:48:03] <Tom_itx> i made one but don't use it
[18:49:17] <Tom_itx> alot of times if we wanted to eyeball a inside radius we'd hold a drill bit up to it
[18:50:17] <Tom_itx> get a full set of thread gages too
[18:51:53] <GammaX-Shop|2> what does linuxcnc use for a probe anyway?
[18:52:18] <andypugh> Anything you want.

[19:26:09] <eric_unterhausen> looks like there may be a kernel version disconnect on the beaglebone black
[19:26:30] <eric_unterhausen> apparently 3.8 is not exactly imminent
[19:47:38] <Tom_itx> do ppl still use 8.04?
[19:50:13] <pcw_home> On older motherboards, sure
[19:51:00] <pcw_home> only easy choice if you have no APIC
[19:52:23] <Tom_itx> would it be asking for trouble if i did the 10.04 update on it?
[19:52:35] <Tom_itx> i had trouble getting 10.04 to work on it previously
[19:53:21] <Tom_itx> or can i just update linuxcnc to 2.5.2 or whatever the current release is and retain 8.04 ubuntu?
[19:56:28] <andypugh> Yes
[19:56:59] <Tom_itx> how would i go about it?
[19:57:08] <Tom_itx> without screwing it all up
[19:57:44] <andypugh> What version are you on now?
[19:57:57] <Tom_itx> i've got ^^ that old pc i've gotten 8.04 to work on and wanted to update
[19:58:02] <Tom_itx> 2.5.1 i think
[19:58:11] <Tom_itx> yes
[19:58:40] <Tom_itx> it's gonna end up in the shop if it works
[19:59:44] <andypugh> In that case you can probably just upgrade through the update manager
[20:00:15] <Tom_itx> well i tried that but it says this version is no longer supported
[20:04:39] <Tom_itx> ok i got it to refresh the list at least
[20:04:48] <andypugh> Who says that about what?
[20:05:04] <Tom_itx> the package manager said that
[20:05:21] <Tom_itx> i prodded a bit and it finally went to get a list
[20:05:36] <Tom_itx> i think linuxcnc was in there
[20:06:33] <Tom_itx> restarting so we'll see...
[20:07:53] <Tom_itx> 2.5.2 now
[20:08:00] <Tom_itx> why can't everything be that easy?
[20:23:19] <tjtr33> re: the supplied 'probe-hole.ngc' , it's a great O-word subroutine, but read it thru before using.
[20:23:28] <tjtr33> This isnt criticism, just be aware it is an example.
[20:23:40] <tjtr33> I annotated it here so I understood what it did ( might be wrong, check it yourself :)
http://pastebin.com/YZ2CFW5v
[20:23:45] <tjtr33> be aware that its imperial, and uses a 6mm dia probe, and returns bolt hole info, and uses some hard coded distances your machine might not be able to achieve
[20:53:55] <dgarr> i made some ngcgui-compatible probe subroutines from cradek's originals. Their defaults would be easy to modify. They can be used with ngcgui or any other way as a subroutine.
[20:53:57] <dgarr> http://www.panix.com/~dgarrett/ngcgui/probefiles/
[20:54:25] <skunkworks> hmm - another problem with mach's trajectory planner... it isn't perfect?
[20:54:40] <skunkworks> http://groups.yahoo.com/group/mach1mach2cnc/message/140393
[20:54:51] <dgarr> also, for testing in a simulator, there is a simple script in scripts/simulate_probe
[20:55:50] <eric_unterhausen> no parport in mach 4? wow
[20:59:07] <skunkworks> sounds like there will be. art supposedly re-wrote it for mach4
[20:59:24] <skunkworks> although it is still a little unclear if it will be included or an extra charge.
[21:11:11] <skunkworks> dgarr: cool! I use those routines a lot
[21:20:11] <gammax-Laptop1> I request some help.... I have a hardinge varigrip pneumatic closer and I need to aquire a electronic solenoid to operate it.....
[21:34:25] <tjtr33> dgarr: nice adding the params to the probe. thx
[21:34:27] <tjtr33> is there a way to detect unit of measure? so a routine could tell if the caller was Metric or Imperial?
[21:34:49] <tjtr33> and if the current plane was G17/18/19 so the probe worked in that plane?
[21:41:39] <dgarr> in master, there is support for a named parameter for the plane: #<_plane>
[21:42:44] <dgarr> and for metric: #<_metric>
[21:45:00] <tjtr33> thx! had not found that. i had written plane dependant inside & outside probes on Heidenhain ( system vars held 'tool axis' rather than circular interp plane )
[21:45:22] <tjtr33> so you can probe on a tomb stone, all sides
[21:45:59] <tjtr33> very nice.. is there a doc describing these system vars?
[21:49:20] <tjtr33> google gives me same list for "linuxcnc '#<_plane>' " as it does for "linuxcnc plane" neither contain "#<_plane>"
[21:49:48] <tjtr33> oh well, grep the master src tree
[21:51:00] <dgarr> the source file is src/emc/rs274ngc/interp_namedparams.cc
[21:53:05] <tjtr33> hmm been in there, thx, i need to look closer
[21:56:56] <dgarr> also a list at:
http://www.linuxcnc.org/docs/devel/html/gcode/overview.html
[21:56:57] <tjtr33> got it init_readonly_param(... thx i blew right by that
[21:57:04] <tjtr33> opps thx again
[21:57:23] <chopper792> Hello all, I am working on a jog pendent and all axis move, but all have the same issue. The issue is no matter what mode the pendent is in (x1 x10 x100 ) the machine always moves at .100" per click. Any clues on what I should look for? Like I said all axis move its just all move .100" no matter the mode of pendent.
[21:59:50] <dgarr> most of the predefined named parameters are available in master only but #<_vmajor> and #<_vminor> are available in 2.5.x (i think)
[22:00:00] <cradek> chopper792:
http://linuxcnc.org/docs/html/man/man9/motion.9.html
[22:00:14] <cradek> here is a listing of motion's input pins including axis.N.jog-scale
[22:00:34] <cradek> you are obviously not getting that set right, according to your knob
[22:01:07] <cradek> so you need to check whatever hal hookups are supposed to set that
[22:01:37] <chopper792> http://pastebin.com/J4dkGaZD
[22:03:12] <cradek> yep looks like that's the stuff to debug
[22:03:30] <tjtr33> does mux4.0.sel0 & 1 respond correctly?
[22:03:32] <cradek> you should perhaps check scale1, scale2, pend-scale, etc with halmeter
[22:05:47] <abetusk_> What do you guys think about attaching a USB microscope to a CNC to measure position for backlash and wear?
[22:06:16] <chopper792> Pendent count works fine in halmeter, but scale is stuck on 0.1" and scale 1 and scale 2 stay false. So it appears I have my pins wrong for scale 1 and 2 I would think
[22:07:06] <cradek> yep I bet you're onto it
[22:07:46] <Tom_itx> pendants are awesome
[22:07:47] <cradek> since you're successfully reading other parport.1 pins your port is working, it seems like it might just be a pinout (or wiring) problem
[22:08:26] <cradek> abetusk: a dial indicator might be simpler, cheaper, and more precise
[22:09:08] <abetusk> cradek, are there digital dial indicators that can work over the full range of motion (say half a foot or so)?
[22:10:00] <chopper792> Sounds like it. That is what I was figuring but needed to bounce it off someone else
[22:10:09] <chopper792> Thanks I will let you know if I got it working
[22:11:05] <tjtr33> thats more stroke than 'dial indicator' has. but linear scales and lvdt s allow that much. are you trying to check long distances?
[22:11:15] <chopper792> quick question.... Scale 1 is = to ? (.1, .01, .001) or nothing like that?
[22:11:38] <abetusk> tjtr33, I'm trying to get a more precise estimate of backlash and wear across the leadscrew
[22:13:14] <L84Supper2> what are the dates for the meet-up in Wichita? 13-19th?
[22:13:28] <Tom_itx> 17-23 iirc
[22:13:39] <L84Supper2> ok, thanks
[22:13:43] <tjtr33> abetusk long distances are often checked with a stack of gauge block against a hard stop. touch off on hard stop, move some distance, feel the gauge in between
[22:13:46] <Tom_itx> i got the link here...
[22:14:00] <tjtr33> for some meaning of 'long'
[22:14:22] <L84Supper2> Tom_itx: I couldn't find the link
[22:14:33] <Tom_itx> http://thread.gmane.org/gmane.linux.distributions.emc.user/42692/focus=42699
[22:14:44] <Tom_itx> it's in one of those replies
[22:14:45] <cradek> yeah glass scales are used for this
[22:14:54] <cradek> it's not clear to me what you'd "point" your webcam at
[22:15:16] <tjtr33> edge of a joe block stack?
[22:15:25] <abetusk> cradek, a reference pattern
[22:15:28] <cradek> not to mention how you'd interpret the picture by machine
[22:15:30] <Tom_itx> From Monday the 17th to Sunday the 23rd
[22:15:30] <tjtr33> edge of a cadillac gauge?
[22:15:38] <cradek> seems like a very wrong technology
[22:16:12] <cradek> a glass scale has a very precise reference pattern and an optical reading device that reads it perfectly into a machine-understandable form
[22:16:42] <L84Supper2> thanks the GFW seems to be blocking/breaking that site
[22:16:43] <cradek> to do that instead with webcams and laser printers or whatever is silly
[22:17:20] <Tom_itx> i'm local so if you need info ask
[22:18:06] <L84Supper2> just incredibly slow
[22:18:21] <tjtr33> maybe an old-school vernier? (tho a magnifying lens is all that Hauser jig-bores put over it, not a camera )
[22:18:39] <cradek> do you want to read it with the machine or by eye?
[22:18:55] <Tom_itx> L84Supper where you comin from?
[22:19:15] <tjtr33> yes cradek, ^^ important point i was missing
[22:19:40] <L84Supper2> Tom_itx: I'll be back in Chicago by then
[22:20:15] <L84Supper2> at a 3D printer Conference in Beijing this week
[22:20:24] <Tom_itx> fun
[22:20:44] <L84Supper2> far more formal that expected :)
[22:20:49] <Tom_itx> the link finally opened?
[22:20:52] <L84Supper2> that/than
[22:21:15] <L84Supper2> yeah,
http://thread.gmane.org/gmane.linux.distributions.emc.user/42692/focus=42699 has the dates
[22:22:15] <L84Supper2> first trip I didn't pack a suit, and all the functions are formal
[22:22:25] <Tom_itx> heh that would suck
[22:23:12] <tjtr33> check out beijing tailors, 24hr turnaround ( check That qc :)
[22:23:34] <Tom_itx> tell em all your bags got lost
[22:23:38] <L84Supper2> yeah, there's a mall in the hotel as well
[22:26:04] <tjtr33> speakin of QC, the lower usb port on the cubieboard is dead :(
[22:26:05] <tjtr33> using a powered usb port expander now off the upper one
[22:26:58] <L84Supper2> they don't sell tools here except for specialty stores, had to go across town just to get an adjustable wrench and a pair of pliers
[22:38:00] <chopper792> cradek: How does the scale get its input for 3 different modes with only 2 pin connections? example would be the pendent is wired for pin 10 = x1 pin11 = x10 pin12 = x100 the common for all them is to pin 14. Is the default always .1 (x100) unless one of the other two (x1, x10) are active?
[22:39:09] <chopper792> I ask this since in hal config under watch I select all input pins and no pins change state when I select x1,x10,0r x100
[22:39:48] <chopper792> almost like the selection knob is not working even though I tested it to make sure that selection knob worked.
[22:43:17] <tjtr33> the 2 wires of the knob are the 'select' lines of the mux. they combine to a binary code 00 01 10 11 that select 1 of up to 4 values for the scale.
[22:45:28] <tjtr33> man mux2 may help
[22:45:34] <chopper792> there are 4 wire for the knob total. x1 x10 x100 and common. Should I be using the x1 and x10 or the x10 and x100
[22:45:43] <chopper792> I am reading mux now
[22:46:29] <tjtr33> sorry i thought your hal paste showed a mux
[22:48:02] <chopper792> it does
[22:48:33] <tjtr33> try man mux4
[22:49:09] <chopper792> with only 2 pin inputs though, so I am trying to understand how 3 selection options with 3 different wires can have only 2 inputs from the pendent.
[22:49:24] <tjtr33> nononono the mux4 selects 1 of 4 outputs using 2 bits input
[22:49:35] <tjtr33> not what you want
[22:50:11] <chopper792> correct
[22:50:51] <tjtr33> you have 3 inputs and want no 'muxing' just use 3 inputs ( 3 pins ) and select the appropo scale when only 1 is true
[22:52:42] <Tom_itx> chopper791 is the logic the level you think it is?
[22:52:46] <Tom_itx> or reversed
[22:52:53] <chopper792> by my logic that is what it should be doing.
[22:53:11] <Tom_itx> one is default and the other 2 switch
[22:53:15] <Tom_itx> that gives you 3
[22:53:27] <chopper792> I did not see the reason for any mux if I had the ability to send it 3 different inputs for my scale factor
[22:54:12] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/configs/sherline/my_jog.hal
[22:54:14] <Tom_itx> there's mine
[22:54:18] <chopper792> ok so .1" is default then as its working that way now and the other two should be the pins for .01" and .001" or x1 or x10
[22:54:44] <Tom_itx> ignore the 'fast' value, it was too fast for my mill so i fudged
[22:55:47] <Tom_itx> mine is input to a mesa card though
[22:56:06] <chopper792> yeah mine is simple...parallel port...lol
[22:56:17] <Tom_itx> the idea is the same
[22:56:39] <chopper792> I have tried all my available input pins and nothing works for my mux inputs.
[22:56:58] <chopper792> no matter the pin it always moves .1"
[22:57:14] <Tom_itx> use a simple switch on the input and make it work with that first
[22:57:18] <tjtr33> you have 3 inputs, they goto hal code that selects a single scale value based on which input is true, that value is connected to axis.N.jog-scale
[22:58:00] <tjtr33> a mux wont do that
[22:58:02] <Tom_itx> 2 inputs and a defalut value
[22:58:08] <chopper792> I have not tried separates yet, by my simple mind that is how it should work.
[23:01:39] <chopper792> let me drink this beer and mess around a bit more
[23:01:54] <chopper792> be back soon and hopefully with a working pendent
[23:02:06] <Tom_itx> i'll read about it tomorrow
[23:02:19] <chopper792> lol
[23:02:41] <gammax-Laptop1> Im comtemplating which probe to buy...
[23:04:45] <gammax-Laptop1> i would like one that can probe very accuratly and also be used as a touch off
[23:04:55] <gammax-Laptop1> but also last a long time. any thoughts?
[23:06:19] <Tom_itx> renishaw is the defacto standard
[23:06:35] <gammax-Laptop1> but is also not an ASS LOAD of money lol
[23:06:37] <Tom_itx> they are simple devices inside
[23:06:45] <Tom_itx> get one off ebay
[23:07:00] <gammax-Laptop1> i cant find a cheap one at all
[23:08:45] <tjtr33> try voltage drop technique: insulate the probe tip, insulate the workpiece , use a pullup resistor to the tip, connect wkpc to gnd, monitor when the tip goes low, use carbide tip
[23:09:00] <tjtr33> cheap, but requires insulation
[23:09:06] <tjtr33> very accurate
[23:10:10] <tjtr33> and keep it clean, air blast & alchohol clean the surfaces
[23:10:30] <Tom_itx> no room for error
[23:10:57] <gammax-Laptop1> yeah im not a fan of that style tjtr33 I thought about it... just rather have an actual probe...
[23:11:11] <tjtr33> ? we used all the time in sink edm, repeats to 2um, as you like
[23:11:42] <Tom_itx> is the tip springloaded?
[23:11:55] <tjtr33> solid in mine
[23:12:20] <Tom_itx> platinum or gold plate the tip
[23:13:13] <tjtr33> soft stuff? again what works proves itself
[23:13:38] <Tom_itx> no, better electrical properties
[23:14:55] <gammax-Laptop1> Tom_itx, did you show me a probe before?
[23:34:55] <tjtr33> Tom_itx, is this what you meant by 'default' on the mux problem?
