[01:48:42] <ssi> nice
[01:52:51] <zeeshan> finally have jack screws
[01:52:52] <zeeshan> lol
[01:52:57] <zeeshan> what are you utpo
[01:53:23] <XXCoder> ew TMI zeeshan
[01:55:16] <LeelooMinai> zeeshan: I bought 4 from KBC once - they have those super cheap (Machinist Jacks): http://kbctools.com/usa/Navigation/NavPDF.cfm?PDFPage=778
[01:56:01] <zeeshan> well two of them are starrett
[01:56:04] <zeeshan> and i really wanted starrets!
[01:56:25] <zeeshan> the other two are fowler :/
[01:56:37] <LeelooMinai> E, is this some kind of machinist world Fluke and Appple equivalent? :)
[01:56:59] <LeelooMinai> Where you pay for the name mostly?
[01:57:03] <zeeshan> nah
[01:57:15] <zeeshan> starrett, mitutoyo make higher quality stuff
[01:57:27] <zeeshan> in comparison to chinese stuff
[01:57:34] <zeeshan> taiwanese stuff for some things comes close
[01:57:36] <LeelooMinai> Yes, but 2x better and 5x more expensive:)
[01:57:48] <zeeshan> well thats unfair to say
[01:57:55] <zeeshan> if you compare chinese collets vs say..
[01:57:59] <zeeshan> glacern collets
[01:58:09] <zeeshan> its 0.0008-0.0006 vs 0.0001
[01:58:11] <zeeshan> runout
[01:58:24] <zeeshan> so in that case ic an say they're 6 to 8x better :P
[01:58:44] <LeelooMinai> Yes, I guess sometimes it's worth the price, but not always
[01:58:44] <zeeshan> i try to buy name brands because they also have a better resale value
[01:58:52] <zeeshan> to give you an example
[01:59:09] <zeeshan> i'd never run a cheapo dial indicator (ahem made in china special) indicator
[01:59:23] <zeeshan> they have huge errors over their travel
[01:59:41] <zeeshan> even the insize dial indicator made in taiwan has about 2 thou over 1"
[02:00:06] <zeeshan> and last reason is i'd liek to support our economy
[02:01:14] <LeelooMinai> Right, well, I don't have moreals like that I'm afraid - I just buy from whomever can offer best value.
[02:01:29] <LeelooMinai> Maybe I will go to hell for this - not sure:)
[02:01:33] <zeeshan> p.s. fluke multimeters make chinese ones look like crap
[02:01:44] <zeeshan> im sure you've seen eev's channel
[02:01:47] <zeeshan> on comparing em
[02:01:55] <jdh> I have fluke, and I have 10 chinese ones
[02:02:08] <LeelooMinai> They made model for CHina too (FLuke).

[02:02:11] <zeeshan> jdh whats your opinion
[02:02:18] <jdh> 99% of the time, the chinese ones are fine for what I need

[02:02:27] <LeelooMinai> I would not buy Fluke multimeter though - they are ok, but far overpriced.
[02:02:32] <jdh> and they are free
[02:02:35] <zeeshan> haha
[02:03:02] <zeeshan> when it comes down to things i care about
[02:03:09] <zeeshan> i liek to buy the good stuff
[02:03:19] <jdh> there are two within reach of me here (and 2 chinese digital calipers)
[02:03:20] <zeeshan> i was rebuilding my trnamission
[02:03:27] <zeeshan> and usually for that stuff the chinese indicators work okay
[02:03:28] <macpod> Hi all, I'm running 2.6.4 currently and found a axis bug. In the opengl display one of the views improperly shows the positions of the spindle. I've taken screenshots but wondered if there is a good ways to do a "dump" of this
[02:03:34] <zeeshan> but man that pos wasn't reading right
[02:03:47] <zeeshan> chinese digital calipers are great!
[02:03:52] <zeeshan> i did a test on them a while back
[02:03:56] <zeeshan> they're just as accurate as a mitutoyo
[02:04:41] <LeelooMinai> I like mine - they only drawback is that after while it requires more zeroings, but it was worth the price ($15 or so:)
[02:04:49] <jdh> $9.99
[02:04:59] postaL_offline is now known as postaL
[02:04:59] <jdh> almost as good as free chinese voltmeters
[02:05:02] <zeeshan> mine were $10 from canadian tire
[02:05:03] <zeeshan> on sale
[02:05:04] <zeeshan> haha
[02:05:18] <jdh> I have seen flakey flukes
[02:05:23] <zeeshan> that being said, i use the mitutoyo only for inspection
[02:05:45] <jdh> spent hours of frustration until I finally tried another meter.
[02:09:50] <ssi> ooh thanks for reminding me
[02:09:58] <ssi> I need to put my fluke 179 on the inventory list
[02:10:36] <ssi> 189 excuse me

[02:22:14] <ssi> sucks for you
[02:22:18] <ssi> I just need tires :(
[02:22:24] <jdh> no kidding
[02:22:24] <ssi> my left rear has a slow leak
[02:22:43] <ssi> I think from running over something nasty in the driveway of the disaster area I used to call a house
[02:22:45] <jdh> what do you do with your non-winter tires in teh winter?
[02:22:58] <zeeshan> store em in the basement
[02:23:11] <jdh> what's a basement

[02:31:46] <zeeshan> man im so glad i ditched diptrace for making schematics
[02:31:52] <zeeshan> autocad electrical is so much better
[02:35:09] <jdh> one is $75, one is $4400
[02:35:23] <zeeshan> meh
[02:35:25] <zeeshan> student version
[02:35:25] <zeeshan> free
[02:35:43] <jdh> thats supporting the economy
[02:36:00] <zeeshan> ??
[02:36:17] <zeeshan> if i was a business i'd buy autocad , solidworks blah blah in a heartbeat
[02:36:27] <zeeshan> i will one day when i have my own consulting firm
[02:36:29] <zeeshan> :-)
[02:37:41] -!- Sigmac has quit [Quit: Leaving]
[02:38:46] <LeelooMinai> zeeshan: I used to use DipTrace for making PCBs - imho it is pretty good for the price.

[02:43:21] <XXCoder> $75?
[02:43:34] <ssi> I got a full eagle license recently :D
[02:44:43] <LeelooMinai> ssi: On #electronics I always recommend DipTrace over Eagle. Most people agree that it has much better usability - it's easier to create footprints, symbols, maintain libraries, etc.
[02:45:03] <jdh> is there a free version?
[02:45:34] <LeelooMinai> Yes, 300 pin max 2 layer is free, or they can increase it to 500 pin max if you request hobby licence.
[02:46:07] <LeelooMinai> If you start with electronics 500 pins is a lot unless you are doing some crazy fpga project.
[02:46:10] <ssi> since I know how to use eagle, I'm not much concerned about that
[02:46:47] <LeelooMinai> I see people always complaining about Eagle there:)
[02:51:18] <skunkworks_> I found eagle very powerful and hard to learn.. :)
[02:52:32] <ssi> I've produced dozens of four layer boards with it
[02:52:49] <ssi> once you learn it, it's pretty good. Has its foibles, but you have to spend a lot more to do better
[02:53:25] <LeelooMinai> I would rate EDAs as KiCAD -> Eagle -> DipTrace -> big gap -> Altium
[02:54:20] <LeelooMinai> Altium has crazy price, so hobbyist would have to pirate it, though they are having some beta program now and plan to have some kind of free "cloud" version.
[02:54:45] -!- FreezingCold [FreezingCold!~FreezingC@135.0.41.14] has joined #linuxcnc
[02:58:23] <MrHindsight> -> Altium -> Allegro :)
[02:58:36] <LeelooMinai> I doubt it
[02:58:49] <MrHindsight> what is the going price for Altium?
[02:58:50] <LeelooMinai> Altium is pretty much at the top there
[02:58:57] <LeelooMinai> $5000 or more?
[02:59:12] <MrHindsight> Allegro full suite is >$40k
[02:59:21] <MrHindsight> just wondering
[02:59:58] <MrHindsight> what became of PADS?
[03:00:06] <LeelooMinai> Because they bought all sorts of software and kind of glued it together. Altium is for schematics/pcbs with some SI, but it's very well designed and integrated.
[03:01:05] <MrHindsight> yeah, they tried to do everything including FPGA design
[03:01:33] <MrHindsight> I used Altium a few times to get the hang of it
[03:02:29] <LeelooMinai> Ok, apparently Altium is $7k or so - kind of too much for average hobbyist:)
[03:02:49] <MrHindsight> deep pocketed DIYers
[03:03:21] <LeelooMinai> imho for hobbyists DipTrace is the best option - it's pretty decent.
[03:04:00] <MrHindsight> does it handle auto trace length matching and controlled impedance?
[03:04:12] <MrHindsight> is it even gridless?
[03:04:37] <LeelooMinai> Last time I used it was 2 years ago (later I used pirated Altium.)
[03:05:05] <LeelooMinai> Not sure what they added since then. Also, depends what you mean by "gridless".
[03:05:42] <MrHindsight> just wondering, I had not even heard of it until now

[03:09:55] <skunkworks_> Working on it about 10 min a day.. (makes for slow going)
[03:10:12] <Tom_itx> ever run into a pulley grub screw backed up by another one?
[03:10:24] <Tom_itx> i guess to keep it from backing out?
[03:10:27] <skunkworks_> yes
[03:10:37] <Tom_itx> i didn't bother looking for two :)
[03:10:41] <skunkworks_> heh
[03:10:45] <skunkworks_> been there
[03:11:09] <MrHindsight> skunkworks_: nice
[03:11:10] <Tom_itx> i had to make a puller for it... it worked wonderfully but left a gulley in the motor flat
[03:11:25] <Tom_itx> i managed to file it out ok though
[03:11:43] <Tom_itx> i probably wouldn't have needed the puller at all...
[03:12:44] <Tom_itx> anyway, i got some timing pulleys ordered for my spindle / motor
[03:12:47] <MrHindsight> skunkworks_: you have it measuring the diameter and XY position?
[03:15:25] <skunkworks_> in the image - yes

[03:17:40] <LeelooMinai> Any reccomendations for what should I look for/buy for a spindle on small CNC of mine (for milling aluminum mostly)? Something that will not be crazy expensive - max $300 probably or so.
[03:18:00] <jdh> chinese 1.2kw water cooled
[03:18:19] postaL is now known as postaL_offline
[03:18:25] <LeelooMinai> I, I saw those - but they require VFD, right?
[03:18:42] <jdh> they usually come as a set
[03:18:55] <jdh> 800w if you want to stay cheaper
[03:19:07] <LeelooMinai> I must be able to plug the thing into normal mains outlet (110V that is)
[03:19:12] <jdh> yeah
[03:19:33] <LeelooMinai> I saw some VFDs that were only for 3 -phase I think
[03:19:50] <LeelooMinai> I cannot really have this in my bedroom:)
[03:20:27] <jdh> http://www.ebay.com/itm/171066636783
[03:21:34] <skunkworks_> they say they stock 110v versions..
[03:21:59] <LeelooMinai> I wonder if I could control it easily with 7i76 I have
[03:22:16] <LeelooMinai> It has some spindle control outputs
[03:22:17] <jdh> yes, or via modbus most likely
[03:24:00] <LeelooMinai> Will look on aliexpress too - a set with mathching bracket would be nice so I can easily attach it to the z-axis
[03:24:39] <LeelooMinai> they have also a lot of air-cooled ones I see - water cooled are better?
[03:25:06] <jdh> never used an air cooled one. my water cooled one is amazingly quiet
[03:25:34] <LeelooMinai> Probably good bearings etc.
[03:26:25] <os1r1s> Anyone use a fog buster (diy or otherwise)?
[03:26:26] <LeelooMinai> I have proxxon rotary tool - when I first turned it on, I thought there was something wrong with it, because I was used to Dremer-like cheap tools.

[05:41:33] <Computer_Barf1> hey connor
[05:42:25] <Connor> Computer_Barf1: Yea
[05:42:41] <zeeshan> connor
[05:42:46] <zeeshan> do you use a contactor to kill your power supplies
[05:42:49] <zeeshan> or a relay
[05:43:08] <Connor> Relay for the Stepper PSU (AC Side) SSR for the Spindle (AC)
[05:43:20] <zeeshan> so when you pres e-stop
[05:43:24] <zeeshan> it kills the power for stepper psu
[05:43:26] <zeeshan> and spindle?
[05:43:28] <Connor> yes
[05:43:32] <zeeshan> do you not lose home?
[05:43:34] <Connor> or will... I'm re-doing everything.
[05:43:41] <zeeshan> by doing that
[05:44:04] <Connor> Yes, You would. But, your suppose to re-home anytime you use e-stop.
[05:44:15] <zeeshan> not that i've seen in industrial machines
[05:44:24] <zeeshan> e-stop is getting abused all the time there
[05:44:25] <zeeshan> lol
[05:44:25] <Connor> or, at least, that's my understanding.
[05:44:41] <Connor> Yes. E-Stop ISN'T a ON/Off or Pause switch.
[05:44:46] <Connor> It's EMERGENCY STOP
[05:44:51] <zeeshan> i know that
[05:44:57] <zeeshan> just telling you how it worked in industrial machines
[05:45:01] <zeeshan> at least the couple ive sued
[05:45:05] <zeeshan> *used
[05:45:16] <zeeshan> i have a problem on my lathe system
[05:45:22] <Connor> Yea. and it's bad teaching / usage or whatever..
[05:45:24] <zeeshan> e-stop kills charge pump which disables the drives
[05:45:33] <zeeshan> but doesn't kill the power supply..
[05:45:41] <Computer_Barf1> http://i.imgur.com/MuKvFIn.png
[05:45:52] <zeeshan> at the same time, an e-stop command is sent over modbus to vfd
[05:45:55] <Computer_Barf1> http://i.imgur.com/fRahEDv.png
[05:45:57] <zeeshan> to put it in "fault mode"
[05:46:12] <zeeshan> see a fault?
[05:46:19] <zeeshan> if the computer freezes up which it has
[05:46:22] <Computer_Barf1> im looking at this guys spreadsheet for what he got for his g0704
[05:46:25] <zeeshan> the modbus command never reaches the vfd!
[05:46:30] <zeeshan> so the spindle keeps turning lol
[05:46:50] <zeeshan> so the way i got around it
[05:46:51] <Connor> Yea, That's not good. You need a way to kill the VFD.
[05:46:52] <Computer_Barf1> but It appears this isn't the "bare essentials" list
[05:46:55] <zeeshan> was enabling the watchdog in the vfd
[05:47:02] <zeeshan> if communication is lost
[05:47:02] <Connor> Computer_Barf1: No, It's not.
[05:47:08] <zeeshan> watch dog puts vfd in fault mode
[05:47:39] <zeeshan> i couldnt kill the 5v supplies
[05:47:44] <zeeshan> cause our drives are retarded
[05:47:49] <zeeshan> and need 5v to disable em
[05:48:05] <Connor> zeeshan: Yea, that's why I'm now killing the AC side of the stepper PSU
[05:48:16] <zeeshan> ah
[05:48:28] <Computer_Barf1> Connor: is that hoss dvd essential? I mean, I'm considering buying a premade kit of the aluminum parts.
[05:48:49] <Connor> Computer_Barf1: No. If your going to buy a conversion kit from someone, it's not.
[05:49:04] <Connor> It's setup so that you can do your own conversion using the machine.
[05:49:19] <Computer_Barf1> so its basically covering how to machine those parts
[05:49:34] <Computer_Barf1> cool
[05:49:38] <Connor> However, be advised, if you do use Ballscrews, you ARE going to need to get the saddle milled out for the ballnut.
[05:50:01] <Connor> Yes, it has the plans for the stepper mounts, ball nut mounts etc etc.
[05:50:35] <Computer_Barf1> yes Ive seeen videos of people doing that. some seem to mill it, some seem to use a drill press, some a grinder
[05:51:05] <Connor> Yea. I'm opting to take it over to a friends house (PeteFromTN) and have him do it on his machine.
[05:51:24] <Computer_Barf1> yes that sounds ideal
[05:51:26] <Connor> along with a bunch of other stuff.. My machine is currently phase 1.. I.E. Using stock screws, not ball screws.. but I have them.
[05:51:48] <Computer_Barf1> Yes im considering just going with stock screws at first.
[05:51:53] <Connor> Along with the stock to increase the Y travel to 9.5"
[05:52:26] <Connor> Once I get mine converted.. I'll have the Z-Top Hat that I won't need anymore.
[05:52:53] <Connor> Happy to donate it once I'm converted as I won't need it.
[05:53:01] <Computer_Barf1> i watched a series of videos where someone was installing a kit, ballscrews and all, but i was wondering if its needed to remove the table if you are sticking with original scews for the time being
[05:53:15] <Connor> No.
[05:53:31] <Connor> You don't need to break down anything on the mill except for taking off the handles
[05:53:50] <Computer_Barf1> do you know what the backlash is with the original acme screws?
[05:54:09] <Connor> .004 to .007
[05:54:13] <Connor> depending on the Axis.
[05:54:50] <Computer_Barf1> yeah that isn't that bad for simple stuff. I'm sure you could do backlash correction too.
[05:54:59] <Connor> Yes.
[05:55:04] <Connor> in software.
[05:55:19] <zeeshan> connor
[05:55:22] <Connor> But, Mine is getting worse due to wear and stuff.. which is why I'm changing out to Ballscrews.
[05:55:35] <zeeshan> can you imagine a scenario where ithe watchdogt on the vfd isn't good enough?
[05:55:37] <Connor> dubble nutted ballscrews.
[05:56:21] <Connor> Watchdog on the VFD? As in.. it stops getting a heart beat signal from the LinuxCNC ?
[05:56:30] <Computer_Barf1> ok i asked this before here but im having trouble grasping it. With linux cnc, the computer is the controller, but i didn't think to ask if there is some sort of breakout beyond the parallel port.
[05:56:31] <Connor> it has it's own Watchdog ?
[05:56:38] <zeeshan> yea vfd has its own watchdog
[05:56:45] <zeeshan> but it monitors rs485
[05:56:50] <zeeshan> if it gets no response
[05:56:53] <zeeshan> it goes into fault mode
[05:57:10] <Connor> zeeshan: Wouldn't thing of anything.. if computer locks up, or goes dead.. rs485 dies..
[05:57:18] <Computer_Barf1> or does the wires from the parallel literally go to the drivers
[05:57:35] <Connor> Computer_Barf1: There is a Break Out Board.. Referred to as a BOB.
[05:57:40] <zeeshan> okay
[05:57:45] <Connor> It's Opto Isolated so that you can't kill the parport.
[05:58:00] <Computer_Barf1> ok yes that makes alot more sense.
[05:58:19] <Computer_Barf1> i assume it probably uses transistors to jump the voltages up on the signals?
[05:58:31] <Connor> No. TTL Signles.
[05:58:40] <Connor> I.E 5v
[05:59:09] <Connor> the drivers are either supplied with 5v and the parport pins switch to ground.
[05:59:13] <Computer_Barf1> and the 5v lines to to the drivers as step/dir?
[05:59:22] <Connor> yes.
[05:59:36] <Computer_Barf1> ok thanks that clears up alot.
[05:59:40] <Connor> Depending on the driver, they can be either source or sync. (+5v or gnd)
[05:59:49] <Connor> I'm switching to MESA
[06:00:06] <Connor> Which is a FPGA Card, and a breakout.. Offloads the Step/Dir generation from the CPU..
[06:00:14] <Connor> and providing way more I/O
[06:00:57] <Computer_Barf1> do laptops have parports anymore? ive not used one in forever
[06:01:24] <Connor> You don't want to use a laptop for a LinuxCNC controller.
[06:01:33] <Connor> Use a Atom based Desktop or something.
[06:01:46] <Computer_Barf1> how about a beaglebone?
[06:01:51] <Connor> laptops have power management and all kinds of stuff that mess up the real time kernels.

[06:03:07] <Computer_Barf1> this looks nice
[06:03:12] <Connor> I try to advise people, at least for their first LinuxCNC build.. to keep it simple, and main stream.. so, standard Desktop PC, with Pport, or Mesa setup
[06:03:45] <Connor> That is a nice control pannel
[06:03:46] <Computer_Barf1> does a mesa not hook up with a Pport?

[06:04:03] <Connor> MESA 5i25 Can ACT as a pport..
[06:04:13] <Connor> with use with specific BOB's
[06:04:26] <Connor> but.. in reality, it is it's own thing..
[06:04:59] <Connor> He also now has a the 7i76E which is a Ethernet Mesa card with the 7i76 breakout board integrated..
[06:05:16] <Connor> So, no PCI or PCI-E Card needed.. just a Ethernet port on your machine.
[06:05:26] <Connor> I went with the 5i25 + 7i76 kit.
[06:07:05] <Connor> http://store.mesanet.com/index.php?route=product/product&filter_name=7i76E&product_id=290
[06:07:53] <Connor> Supports 5 steppers, + Spindle with Encoder + 2 MPG's + Tons of I/O
[06:08:11] <Connor> same thing as this.. http://store.mesanet.com/index.php?route=product/product&path=83_84&product_id=215
[06:09:30] <Connor> I might had went with the 7i76E If I had thought about it.. but.. already planned on the 5i25+7i76
[06:09:48] <Connor> okay. AFK A while.

[11:13:23] Cylly is now known as Loetmichel
[11:15:53] <Loetmichel> hmm... is brass SO much weaker than tinned steel? in steel i have broken a whole bunch of mill bits... in brass the same thickness i can do feed about double and still its not waring at all... -http://www.cyrom.org/palbum/main.php?g2_itemId=15353
[11:16:50] <archivist> brass grabs
[11:17:00] <Loetmichel> ?
[11:17:21] <archivist> and due to the copper is far easier to cut
[11:18:04] <Loetmichel> i thinkt whats costing me the bits is the wweak CNC 604 machine
[11:18:07] <Loetmichel> 6040
[11:18:18] <Loetmichel> wich will bend and break off the mill bits in steel
[11:19:14] <archivist> work hardening and built up edge cause problems with steel
[11:19:22] -!- amiri has quit [Ping timeout: 244 seconds]
[11:24:16] <Loetmichel> shouldnt be a problem for TC bits at all, tho
[11:24:47] <Loetmichel> i really thing the machine is to weak and starts chattering and breaking off the cutting edges, dulling the bit, which in course breaks then

[11:30:44] <SpeedEvil> yeah
[11:31:00] <SpeedEvil> 'weaker' or 'stronger' is generally not the issue if you've got your feeds right
[11:31:59] <Hawku> there is still some limits
[11:32:21] <Hawku> are*
[11:32:52] <Loetmichel> Hawku: yes
[11:34:04] <Hawku> does the bit bounce and chatter againts the steel?
[11:47:13] <Loetmichel> i think so
[11:47:29] <Loetmichel> hard to tell with a 1.2mm 2 flute and 240kRPM
[11:47:37] <Loetmichel> and 24kRPM
[11:47:45] <Loetmichel> and 1200mm/s feed
[11:48:39] <Loetmichel> ahem, for steel i susually take only 600mm/min
[11:48:50] <Loetmichel> not 1200mm/min, thats for aluminium and brass
[11:49:18] <archivist> dry or lubricated
[11:49:27] <Loetmichel> but it sarts to spark after a few meters in steel, so i think it gets dull fast
[11:49:30] <Loetmichel> dry
[11:50:58] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=15074
[11:54:09] <Loetmichel> anyway, as my boss said that brass i s ok for that application i have switched to brass... which is really easy to solder anyway, th get the cornders closed
[11:54:36] <Loetmichel> (couldnt he have said that ~20 casings ago?)
[11:56:27] <Loetmichel> the application is these Formater board cases like the one in the prionter there: http://www.cyrom.org/palbum/main.php?g2_itemId=15341&g2_imageViewsIndex=1
[12:02:43] <Hawku> steel can be very springy material, i wouldn't cut it with a machine made of aluminium
[12:04:08] <Hawku> you have springy material againts machine which can bend

[18:00:44] <Connor> zeeshan|2: Are they all the same ?
[18:00:50] <zeeshan|2> eya
[18:00:51] <zeeshan|2> yea
[18:00:59] <zeeshan|2> just different brand name retags
[18:01:02] <Connor> Why 5 ?
[18:01:07] <zeeshan|2> 5 axis
[18:01:19] <Connor> I thought you only had 3 ?
[18:01:22] <zeeshan|2> i do
[18:01:32] <zeeshan|2> but ill put a and c axis on the table
[18:01:45] <zeeshan|2> want to have the electronics done

[18:02:02] <Connor> Brushesless PWM Servo ?
[18:02:12] <zeeshan|2> does both
[18:02:14] <Connor> I hope that doesn't mean they take IN PWM
[18:02:18] <Connor> only
[18:02:32] <zeeshan|2> it can hanble hall sensors
[18:02:33] <zeeshan|2> tachometer
[18:02:37] <zeeshan|2> and encoder
[18:02:47] <Connor> yea. but 0-10V analog ?
[18:02:52] <zeeshan|2> yup
[18:02:55] <Connor> okay.
[18:03:01] <zeeshan|2> thats why i got 7i77
[18:03:07] <zeeshan|2> which outputs 0-10v analog
[18:03:09] <Connor> just making sure.
[18:03:45] <zeeshan|2> im trying to figure out
[18:03:49] <zeeshan|2> how to test these in the next 30 mins
[18:03:51] <zeeshan|2> quickest way

[19:28:47] <Connor> zeeshan|2: I think I'm using standard Computer power cord for my spindle.. which is rated at 16 amps, but the connector and the power cord might be 10A.. But, it's 18 Gauge which is rated at 16 amps.. So.. I dunno.

[19:33:21] <PCW> I can see a fuse being a higher rating than the power cord (its probably there for PCB/fire protection in the event of power transistor or bridge shorts not for long term overloads)
[19:34:56] <PCW> so its high enough to prevent nuisance fuse blows
[19:36:59] <Connor> I'm slightly worried about using a 10amp cord and 10amp connector with my spindle..
[19:37:18] <Connor> Motor is 1305 Watts
[19:37:50] <PCW> spindles are more likely an issue than servo drives since they tend to stay at high loads for long periods of time

[19:56:26] <cpresser> why does the maj3.component work with bits? wouldnt it be more usefull with float inputs?
[19:56:39] <cpresser> is there something similar for float values?
[19:57:41] <cpresser> anyway, since it uses bits, it should be under point 2.2 in the documentation, not 2.3 http://linuxcnc.org/docs/html/hal/components.html
[19:58:37] <PCW> Not sure what majority would mean for numbers
[20:03:17] <cpresser> i thought its a max(in0, in1, in2) function
[20:10:42] <jdh> I'd call that max()
[20:10:57] <jdh> but, I don't have much imagination
[20:20:07] <PCW> maj3 is a majority vote
[20:21:09] <PCW> you can do it (and maj5) with the lut5 comp
