[01:11:02] <Tom_itx> me either.. i wish you remembered how you did it
[01:12:45] <_methods> i know i had to uninstall the kb that controls the update

[01:14:45] <Tom_itx> i think so
[01:14:51] <Tom_itx> i haven't tried lately
[01:14:54] <_methods> it's more of a pita to disable if it's at the point where you can't run a regular update anumore

[01:15:25] <_methods> if you can still get in windows update uninstall that kb3035583
[01:15:28] <Tom_itx> what is kb 3035583?

[01:30:27] <_methods> hmm weird
[01:30:45] <_methods> ok you will need to reboot now for it to take effect

[01:55:38] <Tom_itx> i asked the prof if he had any more and he gave me the whole lot

[02:09:24] <_methods> my capacitor blew up on the HF tonight
[02:09:32] <_methods> tryin to find a replacement for it
[02:09:33] <PetefromTn_> shit that bites
[02:09:54] <_methods> yeah well it's not biggie since it's just a toy for me
[02:10:06] <_methods> i'm not relying on it or anything
[02:10:27] <PetefromTn_> were you NOT welding with it and just kinda popping the pedal?
[02:10:37] <_methods> http://imgur.com/a/QJdCU
[02:10:39] <PetefromTn_> I understand that is hard on it
[02:10:51] <_methods> ahhh actually i was
[02:10:59] <_methods> i hit the pedal to start the gas
[02:11:16] <PetefromTn_> yeah you don't want to do that too much as I understand it..
[02:11:21] <_methods> ahhh ok
[02:11:45] <_methods> well the caps look like they might have reached the end of their life anyways lol
[02:11:53] <PetefromTn_> I usually just bring the torch CLOSE, tap the pedal to get gas flowing beforehand
[02:11:53] <_methods> they're not exactly new
[02:12:10] <_methods> well i was checkin the gas flow
[02:12:10] <PetefromTn_> then I bring it in to the work and strike the arc
[02:12:16] <PetefromTn_> yeah I figured
[02:13:01] <_methods> but the caps are so old cornell dubilier doesn't identify them the same way anymore

[02:32:59] <_methods> i had to face the electrodes on mine
[02:33:12] <_methods> they were all covered with gunk
[02:33:34] <PetefromTn_> really?
[02:34:03] <_methods> yeah
[02:34:18] <_methods> i think it had been sitting for a long time
[02:34:24] <_methods> probably why the caps blew up
[02:35:18] <tiwake> PetefromTn_: did a bunch of anodizing today and yesterday
[02:35:40] <tiwake> experimented with various different colors and multi-colors
[02:35:44] <tiwake> :3
[02:36:07] <PetefromTn_> tiwake nice man..
[02:36:19] <PetefromTn_> I have yet to play with different colors other than black LOL
[02:36:28] <tiwake> I think I have too much nickel acetate
[02:36:58] <tiwake> the last set I did the parts came out looking meh when they are dry
[02:37:08] <tiwake> but when wet, or slightly oily, they look great
[02:37:24] <PetefromTn_> Woah I had the same problem!
[02:37:38] <tiwake> I think its either that or anodizing went too long
[02:37:45] <tiwake> no idea
[02:37:46] <tiwake> lol

[02:38:18] <CaptHindsight> tiwake: dyes are dyes
[02:38:27] <CaptHindsight> they don't get any smaller
[02:38:30] <PetefromTn_> no idea here either
[02:39:11] <CaptHindsight> darker colors need deeper pores and higher concentrations of dye
[02:39:39] <tiwake> hmm
[02:40:13] <PetefromTn_> so what would cause the dry look?
[02:40:26] <tiwake> I think I might try skipping the nickel acetate and just do water
[02:40:28] <CaptHindsight> rougher surface
[02:40:35] <CaptHindsight> like ground vs polished
[02:40:44] <CaptHindsight> wetting it makes it look smoother
[02:41:13] <PetefromTn_> yeah but what causes it?
[02:41:24] <tiwake> CaptHindsight: not in this case, well at least not from the machined finish before anodizing...
[02:41:25] <CaptHindsight> bright dip also makes it smoother and more glossy
[02:43:01] <tiwake> I think the problem was my acid concentration increased after doing a couple batches, and the most recent one I did the acid eroded the surface in an irregular fashion
[02:43:29] <tiwake> but I have no idea what too much nickel acetate does, so I automatically suspect that too
[02:44:38] <tiwake> or I'm just anodizing my parts a little too long
[02:44:45] <tiwake> 2 hours.. heh
[02:44:59] <tiwake> at 4 amps/ft^2
[02:45:32] <PetefromTn_> I got a very nice black and it looked real deep but I DID get some that were dry looking like that.
[02:46:06] <tiwake> the batch I just did had a noticeably lower voltage than previous batches
[02:46:43] <tiwake> 11-12 volts, instead of the typical 13-14 volts
[02:47:00] <PetefromTn_> I have that wonderfully Chinese power supply and have no real idea what the actual voltage is LOL
[02:47:11] <tiwake> heh
[02:48:06] <tiwake> I'm also trying to set up BOINC on a headless server
[02:48:10] <tiwake> this is a pain in the flank
[02:48:38] <tiwake> boinccmd exists, but everyone says to use the GUI on a remote computer
[02:48:57] <tiwake> cant find hardly any information on it
[02:50:17] <tiwake> meh
[02:53:54] <tiwake> I'm in now with boincmgr
[02:57:08] <PetefromTn_> Sorry man I have NO IDEA what the hell you are talking about ;)
[02:57:13] <tiwake> PetefromTn_: I think its from anodizing too long with the amp setting... I've read that dying "hard anodized" parts is generally never done because the surface looks bad
[02:58:07] <PetefromTn_> I was giving it all my Chinese POS PPS would deal for about 120 minutes
[02:58:34] <PetefromTn_> that was due to the formula info I input based on the surface area
[02:59:16] <minibnz> ahhh dont you hate it when you start cutting gears out and you try to put the center hole in after you have cut the profile... stuffed up my order of opperations.. its cutting the profile first then trying to punch a hole in the center.. but as the job material is up off the deck the gear drops out without a center hole :( glad these were only small gears and only take 5mins to cut another :)
[03:00:48] <PetefromTn_> DOH!
[03:07:38] <Ralith> minibnz: what are you cutting on?
[03:08:03] <minibnz> hmm question.. i am milling some plastic acrylic i think should i use coolant? i notice that when i do deep cuts the slot has a lot of plastic in there. oncce the part is done it chips off easy but was wondering if coolant would help at all..
[03:08:31] <minibnz> Ralith i have a seig X2 mill that i have converted to CNC.. doing a run in plastice before i go cutting metal..
[03:09:01] <PetefromTn_> sounds like its burning a bit
[03:09:16] <minibnz> using a 2mm cutter about 800rmp and a feed speed of 30mm/min (probably too slow)
[03:09:30] <minibnz> yeah the swarf seems like its melted back together..
[03:10:03] <Ralith> I think I've read that going too slow is what causes melting in plastics
[03:10:06] <Ralith> I'm no expert, though
[03:10:26] <Ralith> certainly that seems VERY slow plastics
[03:10:30] <Ralith> for plastics*
[03:12:11] <minibnz> yeah i am still trying to get a handle on all the parameters.. going to hook up a tacho to the spindle so i can start making records od material/cutter size/depth of cut and spindle speeds..
[03:13:50] <minibnz> but i just went in to check my gear. only to find that it lunched the cutter... it broke i three places.. the flutes snapped off.. and then the shank broke in two places, a long section 15mm fell out of the chuck and part (3mm long) stayed in the chuck... weirdest break ever

[03:14:54] <minibnz> the tool holders will come along in time... trying to sort out how i can add a tool changer to the little beast..

http://www.siegind.com/products_detail/&productId=39.html
[03:31:56] <minibnz> ok i have worked out what snapped the cutter... my Zero height was wrong and it tried to do a 5mm deep cut at speed and the cutter could not handle the strain.. still weird how it broke in three places.. maybe the shank got driven into the job?
[03:32:30] <minibnz> maybe it wasnt a 5mm pass but a 15mm pass that would have tried to put the shank of the cutter into the job peice..
[03:32:44] <minibnz> reset job zero height and its seems like its going ok.

[03:39:48] <minibnz> hmmm my gears wont go in the housing... making a planetary gearbox... need to check the measurements to see whats not right.. solidworks says it should fit together.. but thats with zero tollerances..
[03:42:40] <minibnz> maybe its just how im trying to put it together.. if the sun gears are not in the right spot the drive gear will not go in...
[03:43:04] <minibnz> the parts look so nice.. i dont want to have to file them until they work :)
[03:44:37] <minibnz> ok they go in... yay.. but they wont turn.. going to have to file the lobes a little to make it spin...
[03:45:35] <minibnz> next time i will use a 1mm cutter and open up the lobes/teeth just a smidge.. i have 2mm teeth cut with a 2mm cutter so the teeth are lobes (rounded)
[03:47:25] <minibnz> maybe the mill is not perfectly trammed... i noticed it moved once when i was using a fly cutter. maybe it moved between jobs.. really should check this each time i start a job... curse of the tilting post...
[03:48:21] <minibnz> ok i got the gears to turn a few teeth.. certainly needs a little clearance..
[03:49:22] <minibnz> well at least that removes my worries about backlash in this gearbox.. might even be good enough to put onto my Z axis, at least when i cut it out of metal...

[09:30:05] <pink_vampire> morning
[09:34:15] <beikeland> Trying to source proximity switches (preferably cheap chinese stuff). Not finding any with shielded cables, are they OK non-shielded as well?
[09:36:55] <Ralith> they're not exactly high frequency digital devices
[09:37:32] <Ralith> I don't know a lot about the electromagnetic environment steppers/spindles produce but I've never heard of a simple switch needing shielding
[09:38:00] <Ralith> worst-case scenario, shielded cable isn't particularly expensive
[09:39:13] <archivist> steppers do produce electrical noise
[09:39:47] <Ralith> many things do
[09:39:48] <archivist> audio screened cable would be good enough for switches
[09:47:58] <beikeland> i was experiencing spurious limit errors, but i think i tracked it down to a poor connection on the breadboard prototype for my input board.
[09:49:05] <beikeland> its just that i know they exist, found the part numbers, but seems they are not as readily available as their non-shielded counter parts.
[09:50:31] <beikeland> And yeah, my machine has steppers and a normal single phase universal ac spindle with speed control so there should be ample noise :)
[10:02:57] <minibnz> there is noise in my mills controls sytsem.. i just made a PWM to RC servo board that turns my spindle knob, (servo epoxied to the back) used simple fig8 cable and now it picks up noise from the steppers the speed jitters worse when i 'tidy' up the cables.. so i have to replace that with sheilded cable before i use that
[10:03:49] <minibnz> i should have used shielded from the get go but i wasnt thinking when i did that.. it was 4am i had been poking at the pwm firmware all night..
[10:04:43] <minibnz> the bad thing is that i have suitable cable sitting in the other room on the spool...
[10:05:00] <beikeland> i've found some listings but suspect they are incorrect as part numbers and descriptions don't match.
[10:05:09] <SpeedEvil> minibnz: What are you using as the clock source?
[10:05:29] <SpeedEvil> Oh - I read fully - nvm
[10:05:32] <beikeland> i guess i could replace wires, but i'd rather try to get them right, and have the sensor properly shielded as well
[10:07:22] <minibnz> beikeland the factory ones will also probably be water tight too...
[10:07:23] <beikeland> for the rc servo do you have rpm feedback as well? i'm trying to decide on how to approach my kress spindle (800w with speed control)
[10:08:05] <beikeland> minibnz: good point, but with my little toy 3040 machine flood coolant won't be an issue for now
[10:08:08] <minibnz> not yet but i am going to add a hall sensor as a simple tach to close the loop off.
[10:09:00] <minibnz> i have adde flooding to mine.. works a well it goes from just enough flow to i can hose the neigbours cars clean flow...
[10:09:38] <beikeland> for now i'll try to get the rpm reading sorted and see how well the existing speed control works
[10:10:25] <beikeland> lol! but my t-slot bed is made of individual extruded elements so it would probably leak coolant everywhere
[10:10:34] <minibnz> i get 10 steps between just spinning and servo full extension. so on my x2 its about 0-800 and 0-2000rpm.
[10:10:54] <minibnz> i have put a cabinet around mine
[10:11:28] <minibnz> i drilled a drain hold in the the bed to let the water drain but its too small and its blocked after 2 days use..
[10:11:36] -!- Komzpa has quit [Remote host closed the connection]
[10:12:48] <minibnz> i screwed up when i drilled that hole.. it is right over the dove tail slides so it will wash the lube off the slide... maybe i might leave that blocked and drill a bigger one in a better spot.
[10:13:25] <beikeland> haha, thats my main concern, don't want coolant and chips on my rails and scews
[10:16:30] <minibnz> think i will one that is on the side and i can insert a small brass tube so i can clean it easy.. my main drain hole needs some sort of screen it blocks up pretty quick when i get the alu shaving flying..
[10:16:46] <minibnz> think i will ^ DRILL one that
[10:19:25] <beikeland> speaking of spindle control, if using modbus like a vdf to control speed, is it normal for the vfd to have a discrete spindle at speed signal or did i miss it in the serial modbus stuff i looked at?
[10:19:26] <minibnz> im not certain my DRO slides are water proof :( they are just cheap grizzly's i hope they are not getting too wet.. Y is covered by the table and Z is clear but X needed a small alu shield
[10:20:12] <minibnz> hmmm sounds like i should have used modbus instead of a PWM signal :)
[10:20:20] <minibnz> i havent looked at any of the modbus stuff
[10:21:20] <beikeland> i just looked over
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?VFD_Modbus at the way bottom there is some .hal and python stuff that seemed relevant to a diy approach
[10:25:23] -!- Komzpa has quit [Ping timeout: 264 seconds]
[10:27:29] <minibnz> doesnt say anything about it but it could be there it does appear to read the pins of the vfd about 10times a second.. you could probably set up a hal item to handle that,

[12:07:08] <minibnz> ahh gotta love it when you leave the house to go to a mates place and return to a freshly milled gear housing :) gotta love CNC :)
[12:07:35] <minibnz> with a 2mm cutter i dont think it can do a lot of dama ge :)
[12:08:58] <XXCoder> freshly baked gear housing ;)
[12:09:27] <minibnz> yup the smell of wd40 wafting thru the house :)
[12:10:13] <minibnz> just hope i dont piss off the neighbours by being too noisy its 11pm and i am still milling.. i can barley hear the noise in the lounge room i have to mute the tv to hear when it stops
[12:10:32] <XXCoder> you can always surround machine with egg carton foam
[12:10:46] <XXCoder> cheap way to soundproof from what i understand
[12:11:00] <minibnz> hmm thats a idea i do have a plexiglass cabinet on it
[12:11:22] <minibnz> jam the cartons between that and the wall
[12:11:41] <XXCoder> and rubber feet that dont bounce
[12:11:42] <minibnz> new bench might do wonders as well.
[12:11:49] <XXCoder> or I saw in one case, hockey pucks
[12:12:09] <XXCoder> https://gordsgarage.files.wordpress.com/2011/03/puck-feet.jpg
[12:12:24] <minibnz> this is an old chipboard desk all the bit bent when the mill sat on it and i had to pack up the gaps
[12:12:56] <Meduza89> XXCoder: egg carton foam is best at high frequency sound, not at all good in the low frequency ranges
[12:13:20] <XXCoder> interesting. i understand the concept but will never have personal experence.
[12:13:26] <Meduza89> Rock wool is way better as a general absorbent
[12:13:31] <minibnz> seriously you want me to go interrupt not one but four hockey games? thats a lot of way fitter people with sticks than i can handle :)
[12:13:37] <XXCoder> lol
[12:13:41] Meduza89 is now known as Meduza
[12:13:51] <minibnz> that and the only hockey i see aournd me is with a ball on the grass :(
[12:14:08] <XXCoder> Meduza: would dual layers of egg carton foam then rock wool work
[12:14:16] <minibnz> but i do like them :)
[12:14:20] <XXCoder> can buy em online or something I guess
[12:14:41] <XXCoder> got myself curious, now looking up
[12:15:00] <XXCoder> $2 at amazon
[12:15:13] <Meduza> XXCoder: yes, but you would not get so much extra sound proofing from the foam
[12:15:16] <XXCoder> $24 for 12 of em
[12:15:35] <XXCoder> another one, 20 pack for $23
[12:15:44] <XXCoder> geez. not evry expensive.
[12:15:44] <Meduza> Better go with a thicker rock wool plate
[12:15:53] <Meduza> Like 100mm
[12:15:55] <Meduza> Or so
[12:16:11] <XXCoder> interesting. I do want to lessen sound evenually as I have neighbors.
[12:16:21] <minibnz> im kinda pissed off with myself.. i ordered replacment steel gears for my mill.. when i really really should have spent the extra $80 and went for the belt conversion.
[12:16:38] <Meduza> Or, the foam will do a difference on the level inside the cabinet since it allowed
[12:16:42] <XXCoder> GEEZ. 50 pack for $65!
[12:16:48] <XXCoder> way too many pucks.
[12:16:54] <Meduza> Allows less of the higher frequency to escape
[12:17:10] <Meduza> *reflect
[12:17:16] <minibnz> at the moment i have a 10mm layer of styrofoam under a 18mm thick sheet of MDF under my cabinet.. all that on a old woblly desk..
[12:17:38] <minibnz> the thing is jamed against the wall to stop it wobbling when i wind the handles
[12:17:39] <XXCoder> shaky table might affect results
[12:17:44] pjm_ is now known as pjm
[12:17:48] <minibnz> hmmmm
[12:17:56] <minibnz> thats a point..
[12:18:20] <XXCoder> 69 cents for puck holders lol
[12:19:16] <Meduza> A very nice way of soundproofing is to build a inner cabinet with drywall, then adding 100 rock wool, and then adding a double layer of drywall on the outside
[12:19:24] <Meduza> 100mm*
[12:19:32] <minibnz> i am using this python program to convert dxf to gcodes and it keeps ignoring my speed settings.. very anoying when i forget to use the manual speed adjuster so i dont miss steps.. i have to find the code that sets the G0 speeds i think thats what stuffing me up. .the actual cutting speeds are as requested..
[12:20:08] <XXCoder> g0 dont have any speed
[12:20:08] <Meduza> And if you want a nicer sound level inside, you could add egg carton foam to supress high frequency sounds
[12:20:13] <XXCoder> its "rapid"
[12:20:30] <XXCoder> Meduza: I'm not concerned noise for myself
[12:20:41] <XXCoder> just neighbors. I have never heard any sound ever
[12:20:58] <archivist> minibnz, g0 means go as fast as YOUR default settings, so fix them
[12:21:12] <minibnz> ahh i see..
[12:21:29] <XXCoder> yeah g1 (or g2/3 for circle) has speeds.
[12:21:37] <XXCoder> *g2 or g3
[12:21:38] <minibnz> will check the gcode to see if it uses G0's and then fix my emc sesttings
[12:23:46] <minibnz> otherwise i might have to delve into the python program and see if there is a hardcoded speed.. its shame this program hasn't had updates for a long time cuz thats the only real issue i have had with it, if it is a problem with its source.
[12:26:34] <minibnz> need to install a wifi card in the mill so i can mill from the couch :).. how lazy is that..
[12:26:48] <XXCoder> http://www.amazon.com/Blank-Ice-Hockey-Pucks-pucks/dp/B01AF2C0KA
[12:27:04] <XXCoder> 4 of em to help stop vibration from my machine to desk or something? heh
[12:27:54] <minibnz> my cabinet base is 3.5mm aluminium so if i set it up on feet directly it would resonate like bitch right before it bucked under the weight :)
[12:28:18] <minibnz> might get the same if i put them on the mdf sheet too..
[12:28:23] <minibnz> that would suck balls..

[12:51:41] <Frank__2> morning
[12:52:53] <beikeland> Finally found sensors that were NPN, NC (and NO) with shielded wires. $32 for 10 seems okay.
[12:55:00] <Frank__2> limit switches?
[12:56:32] <beikeland> yeah, proximity sensors for limit switches, spent a few days finding someone who didn't just have a "chinese upgrade" in their title, but the actual goods :P

[12:57:08] <beikeland> Seems PNP and NO is most sold by the response from some of the sellers
[12:58:11] <Frank__2> i thought they were more expensive, i still have to order mine
[13:02:59] -!- pcw_home has quit [Remote host closed the connection]
[13:05:40] <minibnz> beikeland they are using prox sensors on 3d printers they might be able to point you to a good one thats cheap..
[13:05:50] <beikeland> Frank__2: I got these

[13:07:11] <beikeland> Could find NPN or NC cheaper, but not with shields. And I also wanted NO+NC so I can add something to monitor that they work, independent of linuxcnc at some point
[13:11:07] <minibnz> is it cheating if i tell my gcode generator that my 2mm cutter is 1.998mm to induce a tolerance?
[13:11:17] -!- tchaddad has quit [Remote host closed the connection]
[13:11:25] <Frank__2> how reliable are those? i need something really serious, i am moving 150kg on 2x 1kw servos
[13:11:50] <minibnz> im not certain i need to yet.. the last gear i cut measures up better than the first one. cut much slower this time.
[13:13:05] <minibnz> Frank__2 i would be worried about over run with a weight that heavy.. different speed different distance past the sensor you will end up.
[13:13:28] <minibnz> you would need two. one to start the slow down to a set speed by the time its hit the next
[13:13:44] <beikeland> Frank__2: lol at that scale I might be tempted to try something that has "omron" printed on them or something
[13:13:51] <XXCoder> first kickstarter by deaf company is taking off pretty well

[13:23:30] <Frank__2> yes, the servos have built in encoders
[13:23:37] <archivist> zeeshan|2, contacts are worth scrap value
[13:23:52] <zeeshan|2> theyre working relays ;P
[13:23:55] <zeeshan|2> im sure someone could use em
[13:24:07] <zeeshan|2> i dont want to use them

[13:24:11] <zeeshan|2> smaller version
[13:24:18] <zeeshan|2> that i have in my other machine
[13:24:41] <archivist> too fussy at line one error
[13:25:00] <minibnz> Frank__2 grab any old mcu and make that your endstop. store the values in the eeprom and reset when you hit the physical limits under controled conditions :)
[13:25:56] <minibnz> what about using a center origin instead of all +XY you will have -x+x
[13:26:06] <Frank__2> thanks for the hel minibnz
[13:26:11] <Frank__2> whats a mcu ? :D
[13:26:28] <minibnz> like a micro controller unit.
[13:26:49] <Frank__2> like mesa cards?
[13:26:58] <minibnz> could be a simple as a 8 pin PIC chip that counts the servos encoder pulses and trips the endstops
[13:27:00] <Frank__2> i will use those
[13:27:20] <minibnz> well if you have a mesa card that is a IO card.
[13:27:55] <Frank__2> i read somewhere that the phase z on the encoder are made to get back to home, by counting revolutions, so i guess that helps?
[13:28:13] <minibnz> it should have a bucket load of inputs and outputs that you could read the servo's encoder directly then you can use linuxcnc to slow down towards the limits regardless of the gcoed
[13:28:22] <Frank__2> yea, i will be having that option with the 7i85s i think
[13:28:28] <Frank__2> as far as i know..
[13:28:37] <Frank__2> exactly
[13:29:22] <Frank__2> is linuxcnc reliable enough for such weight and speeds?

[13:29:58] <minibnz> now if you are trying to get a bit of extra saftey you could add a MCU micro controller unit... this could engage the emergancy stop without the use of the host computer which might be what you want?
[13:30:20] <archivist> no need for mcu at all, its all built into linuxcnc if you learn it
[13:30:28] <minibnz> i think linuxcnc is but the host OS could be an issue.. dont use windows :)
[13:30:39] <beikeland> for extra safety why not have mechanical limit switches, they're dirt cheap? don't need the more accurate proximity switches for that
[13:30:43] <Frank__2> no way

[13:30:57] <Frank__2> linuxcnc use i will
[13:30:59] <minibnz> first time they trigger and they are wiped off...
[13:31:12] <zeeshan|2> i trust a mechanical switch for limit switches
[13:31:24] <zeeshan|2> i hav yet to see prox switches being used as limit switches on an industrial machine
[13:31:28] <beikeland> really? get the type with rollers on so the axis can go past if it wants to?
[13:31:31] <minibnz> 150kg's will have a bit of inertia
[13:31:41] <zeeshan|2> minibnz: you use a lever arm
[13:31:43] <zeeshan|2> so that doesnt happen
[13:31:46] <archivist> I trust soft limits to never get near hardware limits!
[13:31:51] <zeeshan|2> haha archivist
[13:31:54] <zeeshan|2> also on industrial machines
[13:31:57] <zeeshan|2> its not just a limit switch
[13:31:59] <JT-Shop> is there any reason to not ship something to Russia?
[13:32:01] <zeeshan|2> you'll have a dead bolt at the end
[13:32:10] <zeeshan|2> similar to what you see at a train parking spot
[13:32:18] <minibnz> yeah a dead bolt will need to be the size of a house brick..
[13:32:29] <minibnz> of unobtainium...
[13:32:31] <archivist> its called a buffer stop
[13:32:34] <zeeshan|2> minibnz: why talk out of your butt?
[13:33:28] <zeeshan|2> archivist: linuxcnc soft stops have never failed me yet :)
[13:33:31] <zeeshan|2> <3 linuxcnc!
[13:33:34] <Frank__2> ok im getting a headache
[13:33:36] <Frank__2> hahha
[13:33:54] <minibnz> oops sorry not sure where i got that weight from..
[13:34:14] <zeeshan|2> my table weighs 400lb
[13:34:24] <zeeshan|2> and is rated to hold 500lb or something ridiculus like that
[13:34:27] <Frank__2> so the norm for " industrial machinery" is limit switch (home?) emergency switch and hardstop?
[13:34:29] <zeeshan|2> and it still has dead bolts at the end.
[13:34:46] <zeeshan|2> Frank__2: the limit switches are not the home switches
[13:34:52] <zeeshan|2> they are separate
[13:35:00] <zeeshan|2> the home switches wil lbe prox
[13:35:03] <zeeshan|2> the limit will be mechanical
[13:35:16] <Frank__2> so its home switch, limit switch, emergency switch (power off?) and hardstop ? :D
[13:35:23] <zeeshan|2> my machine uses glass encoders so it has a home switch within the glass encoder
[13:35:27] <zeeshan|2> yes
[13:35:45] <zeeshan|2> home marking , not home switch i mean
[13:35:56] <Frank__2> ill need a hell lot of inputs
[13:35:58] <Frank__2> ports
[13:36:50] <zeeshan|2> you could tie all the limits into 1
[13:36:59] <Frank__2> so whats the difference betwen limit switch and emergency switch? the limit switch stops machine by software and emergency switch by power right? how does the emergency switch trigger off
[13:37:17] <zeeshan|2> your emergency stop kills the power to the servo drives
[13:37:18] <zeeshan|2> and spindle drive
[13:37:26] <zeeshan|2> while maintaining power to critical systems like the controller
[13:37:42] <zeeshan|2> thru contactors
[13:37:44] <zeeshan|2> or relays
[13:37:52] <Frank__2> yeah, but thats the big red button right? not something that is triggered by maachine motion?
[13:38:14] <zeeshan|2> it will also have the controller in the chain
[13:38:21] <zeeshan|2> lemme see if i can find a quick diagram of how mine works
[13:38:24] <zeeshan|2> its easier to see in a diagram
[13:38:28] <Frank__2> i see
[13:38:30] <Frank__2> thanks!!
[13:39:27] <zeeshan|2> https://www.dropbox.com/home?preview=IO.PDF
[13:39:33] <zeeshan|2> its at the very bottom
[13:39:40] <zeeshan|2> youl see e-stop and "input#0 7i77
[13:40:00] <zeeshan|2> when you press e-stop , you tell the controller you're in e-stop
[13:40:14] <zeeshan|2> and you trigger a chain of solenoids for the contactors to kill power
[13:40:40] <zeeshan|2> on other machines, you can also trigger the e-stop from the hmi (human machine interface)
[13:40:45] <zeeshan|2> basically that fancy screen you see

[13:41:11] <Frank__2> crap i dont have an account

[13:41:24] <zeeshan|2> tthis will work
[13:42:42] <minibnz> you probably also want to stop the coollant pump with the servos.. dont want to flood the floor if someting goes wrong..
[13:43:01] <zeeshan|2> its all in that chain
[13:44:41] <minibnz> sweet.. i worry about my machine it did something weird the other day when i powered it up.. it shot a quick squirt of coolant out at full speed.. i have to rememeber to point that to the back wehn i power down..

[13:58:58] -!- Komzzpa has quit [Ping timeout: 240 seconds]
[14:09:15] <lair82_> Good Morning guys, have a question, not related to Linuxcnc, but to an old anilam controlled BP style machine. I keep blowing a fuse on the one circuit that goes to the step down transformer ( i believe ) that goes to the rectifier for the power for the drives.
[14:11:12] <lair82_> I pulled the inline fuses out that are between the transformer and the rectifier, and the fuse on the CB blows every time I turn on 120VAC to the machine, I unhook the the transformer from the CB, and turn the power on, and the fuse doesn't blow. Any thoughts?
[14:11:32] <beikeland> minibnz: do you use a charge pump? I have all my outputs on the G540 which has a charge pump, and only use the 2nd port for inputs where there is no need for a charge pump signal. (But I haven't decided on weather or not to include one on the break out board for the 2nd port yet)
[14:12:03] <lair82_> I checked the transformer, and it isn't shorted to ground, and the primary, nor secondary is open.
[14:12:47] <beikeland> lair82_: it could be the sheer inrush current. are you using fast blow fuses?
[14:13:40] <lair82_> Not sure, I will have to check, but it is blowing 20A fuses, it takes 5-10 seconds, then the fuse blows
[14:13:54] <beikeland> and when you say checked, do yo mean continuity test on a multimeter, or high voltage insulation testing?
[14:14:22] -!- FinboySlick [FinboySlick!~shark@74.117.40.10] has joined #linuxcnc
[14:14:40] <beikeland> 5-10 seconds thats sounds strange. if just the inrush current it should blow more or less instantly
[14:14:51] <minibnz> beikland no i got lazy when i built that board it was only meant for test i think i will replace it with something much nicer once i have a complete idea of what i need.. i might need all these outputs with mosfets... i am not pulling that much current thru the mosfets but really should replace it all with proper driver circuit :)
[14:15:05] <lair82_> I used my megger, but didn't check primary against secondary
[14:15:07] <zeeshan|2> cb20?
[14:15:10] <zeeshan|2> cb i mean?
[14:15:22] <zeeshan|2> controller board?
[14:15:30] <archivist> megger can apply too many volts

[14:15:51] -!- SEL has quit [Client Quit]
[14:16:15] <lair82_> I will go back out and double check it. I have a Fluke 1503, so I can select the output voltage, and I am using it at 250V
[14:16:23] <archivist> unplug servos, does it blow fuses, if yes rectifiers and capacitors
[14:16:44] <archivist> servo drives I mean
[14:17:27] <lair82_> I have the fuses pulled out that feed the rectifier that feeds the drives, and it is blowing the fuse that is feeding the transformer
[14:18:04] <archivist> if the only thing left is the transformer then it is dead jim
[14:18:25] <archivist> shorted turns
[14:18:36] <zeeshan|2> did you check the impedance of the transformer
[14:18:40] <zeeshan|2> on both primary and secondary
[14:18:43] <lair82_> The secondary side reads .02 Ohms
[14:18:51] <zeeshan|2> and coil to transformer chassis?
[14:18:56] <archivist> resistance will be low
[14:19:50] <archivist> impedance at 60hz will be different
[14:19:58] <lair82_> I checked all the taps against the case, nothing showed being shorted
[14:20:44] <archivist> shorted turns is an internal fault, causes tit to take too much current and get hot
[14:22:53] <lair82_> the primary side was showing .25 Ohms
[14:23:38] <archivist> I would test with an AC signal and a scope to check for shorted turns
[14:24:17] <minibnz> thats far too low.. Amps = volts/resistance = 120v / 0.25r = 480amps... that be shorted coils buy a new transformer.. or re-wind it..
[14:24:37] <minibnz> if you are on 240v that be near a killowatt..
[14:24:43] <archivist> the DC resistance is always low!
[14:25:23] <archivist> the impedance at the design frequency will be higher
[14:25:44] <minibnz> i would still expect the resistance to be up over 20ohms at least though..
[14:25:48] <archivist> DC meter does not see the inductance
[14:25:52] <zeeshan|2> nope
[14:26:01] <zeeshan|2> those ohms readings are normal
[14:26:07] <minibnz> hmm ok
[14:26:34] <zeeshan|2> could find out from the manufacturer
[14:26:37] <archivist> for a high current transformer those numbers seem sensible
[14:26:37] <zeeshan|2> what its suppsoed to be :D
[14:26:55] <zeeshan|2> i thought i had a short in my servo
[14:26:59] <zeeshan|2> damn thign was reading .4 ohms
[14:27:11] <zeeshan|2> then i busted out the manufacturer spec sheet, right in spec :D
[14:27:57] <zeeshan|2> archivist: shjouldnt you be able to pick up a shorted coil
[14:28:02] <zeeshan|2> w/ an inductance meter?
[14:28:12] <zeeshan|2> cause the henrys will be lower
[14:28:14] <zeeshan|2> than spec
[14:28:23] <archivist> yes it will show
[14:29:18] <archivist> it will damp any attempt to make the inductance "ring" as well
[14:30:13] <zeeshan|2> my friend gave me a big ass servo
[14:30:15] <zeeshan|2> i need to check if its good
[14:30:27] <zeeshan|2> speaking of henrys.. i should check w/ the meter

[14:56:38] <zeeshan|2> lair82_: is it a simple transformer
[14:56:44] <zeeshan|2> with one primary and one sercondary
[14:56:54] <zeeshan|2> or does it have multiple secondaries with center taps also
[14:59:58] <lair82_> multi tap primary (120/240) and the secondary has 3 terminals on it, we are using terminals 1 and 2
[15:00:14] <zeeshan|2> whats the secondary voltage
[15:00:19] <zeeshan|2> could you nolt just get a standard transformer
[15:00:23] <zeeshan|2> with your primary (240)
[15:00:27] <zeeshan|2> and your desired secondary

[15:07:59] <zeeshan|2> just be careful though
[15:08:12] <zeeshan|2> if that's REAL power or apparent power
[15:09:03] <lair82_> He said it is an 82 volt secondary, with a 75 volt tap, and looking at the build sheet, it is capable of about 30 amps on the output

[16:29:58] <CaptHindsight> is/in
[16:31:18] <FinboySlick> Sort of reminds me of Hydro-Quebec's Wheelmotor, which they licenced to Dassault

[16:33:17] <archivist> I had one in my hands a couple of years ago, the magnets bite
[16:36:52] <CaptHindsight> probably ~400w motor so similar to Chrysler minivan
[16:41:41] <CaptHindsight> http://hackaday.com/2013/04/01/windmill-made-from-washing-machine-555-chip/ here's a hackaday tie in as well to give it legitimacy
[16:43:05] <CaptHindsight> are the prices at Automation Technology going up or are others starting to sell the same parts for less?

[16:47:00] <gregcnc> continuous torque should be something like 1-2 Nm per cm^2 of airgap area for a decent quality BLDC motor, but I would guess this motor is lower. very good designs can approach 4 Nm/cm^2

[18:02:11] <pcw_home> Maybe but its not a high priority
[18:02:21] <CaptHindsight> the older core 2 duo laptops have Linuxbios now
[18:02:26] <pcw_home> (since you can use a 7I92M/7I77)
[18:02:32] <CaptHindsight> I think they RE'd the EC's as well
[18:02:36] <AmsterdamJoe> pcw_home: i dont know if this is relevant but there is some Libre boot project for open bios firmware
[18:03:00] <CaptHindsight> i think they still had LPT ports

[18:09:33] <pcw_home> ( Chord errors are in the 1/10000 inch range with moderate acceleration (1/2 G or so) )
[18:11:08] <Sync> don't you get a progressively larger velocity error?
[18:11:32] <Sync> or does it spit out the pulses averaged over the period?
[18:12:32] <pcw_home> the problem is your curve is done with 4MS long straight lines
[18:13:50] <pcw_home> the error is proportional to acceleration/servo thread frequency^2

[21:58:10] __rob2 is now known as __rob
[21:58:55] <__rob> can anyone tell me if I should be putting tool offsets into autodesk cam, if they are measured already in the control software
[21:59:14] <__rob> seems like that is surely redundant
[21:59:23] <zeeshan|2> what do you mean
[21:59:32] <__rob> well, they tormach measures the tool lengths
[21:59:38] <__rob> on the digital tool setter
[21:59:45] <__rob> so it knows where the tip is for each tool
[21:59:53] <__rob> but in Inventor, I can also enter in the length of each tool
[22:00:03] <zeeshan|2> im not sure about inventor
[22:00:11] <zeeshan|2> but in mastercam, the length of the tool is there for simulation only
[22:00:14] <__rob> well its the same as Fusion 360
[22:00:15] <__rob> I guess
[22:00:22] <zeeshan|2> the tool tip comes directly from your controller
[22:00:33] <zeeshan|2> but you also have the option to offset the tool tip
[22:00:43] <zeeshan|2> so it's relative to what the controller wants
[22:00:58] <zeeshan|2> __rob: easy to test whats going on
[22:01:01] <__rob> yea, so tool offset in the cam makes no difference
[22:01:06] <Lowridah> so in the last year or so I've bought, built, rebuilt 5 3d printers.. i wanna get into cnc routers for aluminum prototyping, would it be a really really horrible idea to start with a chinese 6040 kit?
[22:01:06] <__rob> yea, well it seems to work
[22:01:07] <zeeshan|2> pocket a hole
[22:01:09] <__rob> which is why im confused
[22:01:11] <zeeshan|2> ah

[22:01:42] <__rob> I guess it can't properly detect collisions between the holder and part
[22:01:48] <__rob> with incorrect tool heights
[22:01:48] <zeeshan|2> yes
[22:01:55] <__rob> so apart from that
[22:02:02] <__rob> the gcode will be the same, regardless of tool height ?
[22:02:08] <zeeshan|2> yes
[22:02:18] <__rob> cos Pathpilot already seems to zero the same place on all tools
[22:02:44] <__rob> right, ok thats nice and clear now
[22:02:49] <__rob> thanks alot
[22:03:12] <zeeshan|2> np
[22:03:16] <zeeshan|2> offsets are confusing :P
[22:03:25] <zeeshan|2> no matter how much i read about em
[22:03:31] <zeeshan|2> i had to experiment with the cnc controller

[22:06:57] <Tom_itx> i'll do a few that look interesting
[22:07:22] <Tom_itx> i like the pattern better in catia over sw
[22:07:28] <Tom_itx> at least so far
[22:07:42] <Tom_itx> it will follow 2 edges and have varying offsets

[23:05:13] <andypugh> Wierd. I went out to the workshop this evening to work on the lathe project, and found that I just couldn’t be bothered.
[23:06:32] <andypugh> I can’t decide whether it is because it looks like the lathe needs an unexpected bed regrind, or because i have a stupid cough and haven’t slept properly for two weeks. Or something else.
[23:07:20] <XXCoder> oh damn forgot to bring my dial indictor home again
[23:07:35] <XXCoder> I wanted it to make sure spindle is T to surface
[23:08:30] <andypugh> XXCoder: top tools for that, a coaxial indicator and a cheap replacement brake disc (unused)
[23:09:05] <andypugh> pink_vampire: “ On a side note, historically, many pink vampires have been mistaken for witches, and vice versa. This is a matter of much debate within the occult community. The issue first arose when it was shown that Glenda the Good Witch from "The Wizard of Oz," was in fact a pink vampire rather than a true witch.”

[23:14:01] <XXCoder> andypugh: maybe happened to be overproduced

[23:31:10] <enleth> I don't even. The heidenhain control went tits up again yesterday in the middle of a job after several hours of normal operation, same as usual, and again it started working as soon as I connected a multimeter set to 200V DC between two specific points in the I/O board.
[23:31:21] <zeeshan|2> i must be retarded
[23:31:24] <zeeshan|2> what is calling do_Change
[23:31:25] <enleth> I'm leaving the damn multimeter inside for real now.
[23:31:36] <zeeshan|2> oh
[23:31:38] <zeeshan|2> its at the very bottom
[23:31:39] <andypugh> XXCoder: I don’t even know what it means. I onluy know it as an eBay search term
[23:31:43] <zeeshan|2> do_change(h.number)
[23:31:54] <XXCoder> andypugh: multi-arcade machine emulator
[23:32:10] <zeeshan|2> where is h.number coming from :D
[23:32:13] <XXCoder> andypugh: its system where it can emulate many old arcade machines. mame itself is free
[23:32:48] <XXCoder> however its far better with real machine. that is where ebay term 'mame' come in for buttons lights so on
[23:33:07] <enleth> andypugh: seconding the MAME suggestion. There is a whole industry dedicated to production of buttons, joysticks and switches resistant to being smashed and pulled at furiously by angry losing gamers
[23:33:18] <pink_vampire> http://i.imgur.com/zopeOzP.png
[23:33:25] * XXCoder wonders if mame can effectively run on my CHiP computer.
[23:33:31] <zeeshan|2> jesus
[23:33:34] <zeeshan|2> the cabinet is bigger than the machine
[23:33:46] <XXCoder> pink_vampire: did you see my last aliexpress link?
[23:33:48] <Jymmm> XXCoder: As in the emulator? probably
[23:33:49] <Tom_itx> zeeshan|2 so is mine
[23:34:00] <zeeshan|2> Tom_itx: =D
[23:34:01] <zeeshan|2> cute
[23:34:04] <XXCoder> its exactly same as you wanted, only 10% price ($1.50)
[23:34:19] <XXCoder> Jymmm: yeah was pretty sure but dont need to be that tiny though lol
[23:34:27] <pink_vampire> XXCoder: I saw.. but I want the original
[23:34:37] <Tom_itx> zeeshan|2 but my cabinet would run a machine 4x bigger
[23:34:39] <XXCoder> its handy if I want to make tiny arcade booth LOL
[23:34:46] <Jymmm> XXCoder: what do you have?
[23:34:48] <andypugh> That’s how I found the buttons I used on the Mill controller. Slightly cheesy, but certainly functional:

[23:34:55] <pink_vampire> so.. what do you think about the design?
[23:35:20] <XXCoder> Jymmm: I have 3" tv and chip, basically all I need. just make console by cnc and done. so tempted now.
[23:36:05] <pink_vampire> andypugh: but you can use oled buttons
[23:36:12] <XXCoder> pink_vampire: is power indictor light also a button?>
[23:36:16] <Jymmm> XXCoder: and go blind in the process
[23:36:25] <XXCoder> Jymmm: yeah that tv is crap
[23:36:35] <XXCoder> it was made for back up car montior
[23:36:36] <andypugh> pink_vampire: I am sure I could. Except I would rather be machining :-)
[23:36:46] <XXCoder> so resolution is very low.

[23:37:21] <XXCoder> pink_vampire: very effective design I guess. it probably could run much larger machine too
[23:37:37] <andypugh> pink_vampire: Have you considered putting all the electrnics inconveniently in the base of the mill, and having a monitor (with the PC mounted on the back ) on a swinging arm?
[23:37:41] <XXCoder> just make sure e-stop is always easy to hit
[23:38:16] <pink_vampire> I have 2 E-stops
[23:38:42] <pink_vampire> one in on the left top corner of the panel
[23:38:56] <pink_vampire> and one is next to the machine
[23:38:57] <andypugh> pink_vampire: Oooh! That is a cute button. Now what project can I think of to justify using it?
[23:38:59] <XXCoder> pink_vampire: you havent answered my quetsion heh
[23:39:18] <XXCoder> pink_vampire: is power indictor light also a button?
[23:39:23] <pink_vampire> and I can add anather one on the 20" screen
[23:41:07] <andypugh> pink_vampire: This is my mill, which is muvh like yours, but better because it was made in Yorkshire.

[23:41:32] <pink_vampire> the main SW power the first green light, the momentary power lock the contactor and power the second green light
[23:41:43] <XXCoder> andypugh: exposed belt on front is very safe
[23:42:06] <andypugh> The PC and Mesa cards live behind the (touchscreen) monitor. The VFD and motor drives are in the machine base. It works for me.

[23:42:35] <pink_vampire> andypugh: it's look very nice design..
[23:43:02] <andypugh> XXCoder: Wht could _possibly_ go wrong with a whirling pulley at crotch height?
[23:43:18] <XXCoder> anyone, is that light indictor also a button? I know some thats like that
[23:43:22] <pink_vampire> the screen is only for monitoring the panel
[23:43:37] <pink_vampire> it is not for the cnc controller
[23:43:38] <XXCoder> andypugh: nah nothing go for it
[23:43:46] <pink_vampire> for that I have anather screen
[23:44:01] <andypugh> XXCoder: Guess what this is:
https://picasaweb.google.com/108164504656404380542/HarrisonMill#6240922937265481842
[23:44:43] <pink_vampire> the screen on the panel going to show stuff like that
http://i.imgur.com/lR5yEPb.png
[23:44:45] <XXCoder> looks like magetic holder , and youre making new cover for that fun mangler belt?
[23:44:53] <andypugh> Though I did run for two years with the exposed belt and no mishaps
[23:45:14] <XXCoder> yeah it helps that it has sides still on. less chance
[23:45:15] <andypugh> (and right on both counts)
[23:45:26] <cradek> that looks like a casting that the flycutter is about to pitch across the room
[23:46:03] <andypugh> cradek: I was somewhat nervous, but at least it would throw it away from the operator
[23:46:31] <XXCoder> heh I remember "air blackouts" at old work
[23:46:39] <XXCoder> we was using air pressure to hold parts
[23:46:43] <pink_vampire> the screen on the panel it's for monitoring voltages, current, temperature, vibration, etc..
[23:46:45] <XXCoder> flying part aloy!
[23:47:08] <XXCoder> thankfully we used pipe and plastic sheet stand to block part from going across shop
[23:47:12] <_methods> heh that horizontal i scored for $100 happened to be a brown and sharp #2
[23:47:15] <pink_vampire> hope It's not over kill..
[23:47:18] <XXCoder> made a nice dent in plastic
[23:47:22] <_methods> is going to fit in my garage perfect

[23:47:45] <andypugh> pink_vampire: It is overkill. You could have a monitor tab on the main GUI.
[23:47:55] <XXCoder> anyway that shop upgraded one BIG air tank to 4 of em
[23:47:56] <_methods> i didn't realize a brown and sharpe #2 is much smaller than a cincinnati #2
[23:48:06] <XXCoder> never had air pressure blackouts since
[23:48:52] <XXCoder> poor mogwai
http://www.optipess.com/2015/02/23/mogwai-meal/
[23:48:53] <_methods> andypugh: do you have 3 phase for your harrison?
[23:48:58] <_methods> or do you have it on vfd?
[23:49:09] <andypugh> pink_vampire: I spent £350 and 2 months patternamaking on my lathe conversion. That was overkill too. It’s a hobby. You choose the overkill that makes you happy.
[23:49:57] <andypugh> pink_vampire: (I missed out the phrase “one-off iron castings” in that sentence
[23:50:07] <andypugh> _methods: VFD
[23:50:16] <_methods> howd you hook yours all up?
[23:50:23] <_methods> i have like 3 motors on mine
[23:50:31] <_methods> 1 is just coolant pump i guess
[23:50:46] <_methods> but the looks like 1 is for spindle and the other is for the table

[23:50:53] <pink_vampire> I want is nice and clean design, because it's inside the home
[23:51:00] <pink_vampire> on the living room
[23:51:59] <andypugh> pink_vampire: Consider oak. This is my living-room lathe:
https://picasaweb.google.com/108164504656404380542/Rivett#5978884791542655522
[23:52:11] <_methods> work of art those rivetts
[23:52:14] <malcom2073> Lol
[23:52:28] <malcom2073> andypugh: Do you actually use it in there?
[23:52:38] <malcom2073> Or is it decoration?
[23:52:44] <XXCoder> or both
[23:52:47] <pink_vampire> andypugh: wow that look soo nice comper to the milling machine.
[23:53:52] <andypugh> _methods: The main spindle is on a VFD. (I paid to have the motor converted, it wasn’t a 6 terminal motor). The coolant pump was converted with just a capacitor. The feeds are all CNC and run by 8i20s.
[23:54:10] <_methods> ahh yeah i forgot you converted yorus
[23:54:27] <_methods> i'm going to use mine manual for ow
[23:54:29] <_methods> now eve
[23:54:31] <_methods> even
[23:54:37] <_methods> jeebus i can't type tonight
[23:54:37] <XXCoder> andypugh: is living room lathe operatal and you use it sometimes?
[23:55:09] <_methods> guess i'll need a 2nd vfd for the feeds
[23:55:26] <andypugh> malcom2073: It works. I have no real use for it. I do plan to ditch the carpet (it’s got a serious swarf and grease problem in places)
[23:55:41] <malcom2073> Hah that was what I was wondering :)
[23:55:52] <Erant> On an unrelated topic, I'm tired of my shitty-ish caliper giving me pseudo-random readings. Any tips for a decent caliper? I'm looking at some used Mitutoyo CD-6s on eBay, but I'm a little worried about knock-offs...
[23:56:03] <_methods> mitutoyo
[23:56:17] <pink_vampire> I want to die
[23:56:24] <XXCoder> Erant: try replace battery first but yeah mitutoyo
[23:56:58] <XXCoder> Erant: el cheapo calipers cant handle low power
[23:56:59] <Erant> XXCoder: Oh, I did. It's not WAY off, but I'd like a little more repeatability
[23:57:04] <PetefromTn_> Mitutoyo
[23:57:12] <andypugh> malcom2073: Top make a point, I just turned it on and made a wee bit of swarf :-)
[23:57:17] <malcom2073> Nice
[23:57:41] <XXCoder> Erant: just dont buy one off ebay or something, chances is its chinese ripoff that uses power wrongly
[23:57:43] <_methods> dial calipers i'd say mit and starret
[23:57:52] <XXCoder> you'd need to replace battery each month
[23:57:52] <_methods> but digital mit is a no brainer
[23:57:56] <pink_vampire> I solve one thing anf the other become mess
[23:58:15] <PetefromTn_> I like a good dial caliper too
[23:58:26] <andypugh> pink_vampire: You may be disappointed. So far only 95% of people have demonstrated an ability to die.
[23:58:27] <_methods> i have dials and digital
[23:58:36] <_methods> i just grab whichever is closer lol
[23:58:41] <Erant> XXCoder: I was going to go find a used Mit. I already have a nice Mit micrometer.
[23:58:41] <_methods> being the lazy turd that i am
[23:58:58] <XXCoder> my work test indictors is mitutoyo and starret, and I like mitutoyo one little better
[23:59:13] <PetefromTn_> I only have digital calipers here but I do have some old verniers ;)
[23:59:23] <pink_vampire> andypugh: ocd.....
[23:59:42] <pink_vampire> http://i.imgur.com/30KsriJ.png
[23:59:44] <pink_vampire> whyyyyy
[23:59:53] <andypugh> The thing with calipers is that they need SR not LR batteries. Then they are all good.
