[00:00:14] <Tom_itx> andypugh is yours the mega328?
[00:00:16] <andypugh> Jymmm: I have a gnd wire. Yes. But they are shared elsewhere too.
[00:00:23] <andypugh> No, Uno
[00:00:42] <Tom_itx> right but what is the main chip?
[00:00:57] <Jymmm> jthornton: Miss July gave us a private show
[00:01:08] <jthornton> shoot

[00:04:59] <andypugh> I guess Atmega368
[00:05:08] <andypugh> As that is the one I have a datasheet for
[00:05:49] <Tom_itx> 328?
[00:06:10] <Tom_itx> that's one of the more common ones now
[00:07:40] <andypugh> Yes, 328. I must have the wrong datasheet :-) http://arduino.cc/en/Main/ArduinoBoardUno
[00:08:41] <andypugh> If space is short: http://arduino.cc/en/Main/ArduinoBoardNano
[00:09:48] <andypugh> Oh, I just realised, I was wrong. Mine is a Duemillenova (ATmega328p)
[00:10:43] <Tom_itx> they're all relatively the same code wise
[00:11:37] <Tom_itx> the U4 would be another good choice as it has onboard adc

[00:18:30] <Jymmm> jthornton: Free Boat http://sfbay.craigslist.org/sby/zip/3142992707.html
[00:19:33] <jthornton> come get this trash I can't toss out without getting in trouble LOL
[00:20:14] <Jymmm> BOAT == Buck Out Another Thousand
[00:20:21] <andypugh> It seems that the motor was removed using a chainsaw?
[00:20:43] <Jymmm> sawzall?
[00:20:57] <Tom_itx> a turd on wheels?
[00:21:14] <Jymmm> no, triailer not included
[00:21:40] <Jymmm> Just a teal turd
[00:31:11] <Nick001> Back with that multiple spindle question including 1 or 2 of them doing rigid tapping. can it be done in axis?
[00:35:05] <skunkworks__> rigid tapping? that is a linuxcnc thing - not really a UI thing
[00:35:42] <Nick001> UI -- ?
[00:35:53] <skunkworks__> user interface - like axis
[00:36:05] <skunkworks__> unless I am miss-understanding your question
[00:36:55] <Nick001> just trying to control multiple drilling and tapping spindles on a special machine
[00:37:01] <skunkworks__> oh
[00:37:33] <skunkworks__> do they all move independently? or are they fixed?
[00:37:54] -!- rob_h has quit [Ping timeout: 264 seconds]
[00:37:58] <Nick001> 6-8 spindles each on its own slide independantly contolled
[00:38:16] <Nick001> controlled
[00:38:37] <skunkworks__> so - each one has its own 'z' axis?
[00:39:12] <Nick001> right and 1 extra rotary spindle for rotating the part
[00:39:55] <skunkworks__> you lost me again
[00:39:58] <skunkworks__> :)
[00:40:03] <Nick001> spot,drill, tap in 90 deg apart
[00:40:21] <skunkworks__> picture?
[00:40:24] <r00t4rd3d> is measurement determined differently in Windows compared to Linux?
[00:40:35] <r00t4rd3d> well now that i read that i am sure it is
[00:40:52] -!- Valen [Valen!~Valen@c122-108-45-139.blktn6.nsw.optusnet.com.au] has joined #linuxcnc
[00:40:57] <r00t4rd3d> calculated would be a better word for determined
[00:41:04] <Nick001> cross drilling and tapping a hub in 2 positions
[00:41:31] <Nick001> picture tomorrow
[00:42:05] <jdh> math pretty much just works in windows too.
[00:44:17] <WillenCMD> Nick001: You could write a gladevcp program to do it all
[00:44:27] <skunkworks__> Nick001: well - Hal gives you the abillity to connect/disconnect joints from motion
[00:45:06] <Nick001> thats all new to me - I just got a Hardige running
[00:45:31] <skunkworks__> might take some thought
[00:45:31] <Nick001> any info on connect/disconnect joints from motion
[00:47:41] <WillenCMD> halcmd tutorials are few an far between
[00:47:50] <Nick001> alot of thougt - just smoked an H-bridge trying to get a motor going
[00:47:50] <skunkworks__> Nick001: what h-bridge?
[00:48:00] <Nick001> hooked up to etch-servo - from spark-fun
[00:48:41] <Nick001> might have overdone the PID
[01:01:29] <andypugh> Nick001: If you are prepared to use M65 (or M68, something like that) to set spindle speed then it is relatively easy. If you want to use for example, M3.1, M4.1 to start and stop spindles then it's a bit more tricky. If you want to overload the S word to set more than one spindle speed, then I have no idea how you would do it.
[01:01:53] <andypugh> Are you planning to use more than one spindle at a time?
[01:02:16] <andypugh> And I don't know why I am asking questions, I am going to bed.

[02:22:15] <r00t4rd3d> everyone on bath salts without me or something?
[02:22:35] <ReadError> bogarting the bathsalts
[02:22:52] <ReadError> how did family guy cut turn out
[02:23:04] <r00t4rd3d> my coupler came loose
[02:23:08] <r00t4rd3d> BLAST!
[02:23:16] <ReadError> man you cant catch a break huh
[02:26:22] <r00t4rd3d> everytime i attempt that one something goes wrong
[02:26:41] <r00t4rd3d> my shaft broke on the first attempt
[02:27:25] <r00t4rd3d> im messing with lego batman and topo maps of the us now
[02:29:55] <Tom_itx> you better do something about that mount
[02:35:43] <r00t4rd3d> what mount?
[02:35:53] <r00t4rd3d> motor mount?
[02:38:10] <r00t4rd3d> ive changed the way i cut somewhat. I was using my X axis, the longest of all, to do most of the moving. Now i use my y axis to do the majority of moving, at least for inlays
[02:38:55] -!- mcenter has quit [Quit: Ex-Chat]
[02:39:26] <Tom_itx> well the shaft needs to be aligned or the same thing will happen again
[02:39:35] <r00t4rd3d> it is now
[02:39:38] <Tom_itx> and if it's not a rigid mount you should have a flex joint
[02:39:40] <r00t4rd3d> perfectly
[02:40:03] <Tom_itx> like andy said the other day, tighten the coupler then the mount
[02:40:35] <r00t4rd3d> i can unhooke both ends of my lead screw , slide and gantry back and forth and my lead screw goes in and out the bearing block holes.
[02:41:12] <r00t4rd3d> and=my
[02:41:14] <r00t4rd3d> i think
[02:41:19] <r00t4rd3d> slide my
[02:42:56] <r00t4rd3d> i made sure it was dead even with the coupler too, i could slide the shaft right into the coupler after i mounted it to the shaft
[02:43:02] <r00t4rd3d> err mounted to lead screw

[02:53:02] <r00t-Shed> thats what i am doing now :)
[02:54:00] <r00t-Shed> i was looking at my screenshot and i thought the program froze
[02:54:07] <r00t-Shed> i almost hit estop
[02:55:09] <Tom_itx> what are you doin with all those?
[02:55:34] <r00t-Shed> burning barrel
[02:56:10] <r00t-Shed> some crap my friends take
[02:56:53] <r00t-Shed> my one friend sanded up and painted a harely logo i did and it actually looks pretty good
[02:57:32] <r00t-Shed> he painted it with bed liner
[02:57:59] <r00t-Shed> i will get a pic of it
[02:58:41] <uw> what do you use to generate the gcode?
[02:58:52] <r00t-Shed> wand
[02:59:17] <r00t-Shed> Microcarve
[02:59:56] <Tom_itx> how much is it?
[03:00:04] <r00t-Shed> 32 bucks or something
[03:00:16] <r00t-Shed> the guy who makes it is cool too
[03:00:18] <Tom_itx> v4?
[03:00:22] <r00t-Shed> yeah
[03:00:31] <r00t-Shed> he also makes z axis
[03:00:37] <Tom_itx> from pics like jpeg etc?
[03:00:41] <r00t-Shed> yeah
[03:00:52] <Tom_itx> what's z axis?
[03:01:02] <r00t-Shed> i find what i want to cut on google image searches
[03:01:09] <r00t-Shed> a Z Axis?
[03:01:20] <r00t-Shed> the part that moves up and down and holds your router
[03:01:31] <Tom_itx> <r00t-Shed> he also makes z axis
[03:02:02] <r00t-Shed> hold
[03:02:42] <uw> i think he means the actual part that moves the router up and down
[03:02:54] <uw> he just sells that and you have to figure out the x-y

[03:06:30] <Tom_itx> does it run in windows or linux?
[03:06:35] <r00t-Shed> windows
[03:06:43] <r00t-Shed> but we are working on that
[03:06:50] <r00t-Shed> i just got it to run under wine
[03:07:04] <r00t-Shed> but i had to start from a git clone and patch wine
[03:07:14] <r00t-Shed> build it all from source
[03:07:18] <Tom_itx> what's the difference between microcarve and micropath?
[03:07:25] <r00t-Shed> path is old version
[03:07:49] <Tom_itx> wonder why he still sells it if there's a new ver
[03:08:19] <r00t-Shed> cheaper?
[03:08:43] <Tom_itx> what's 5 bucks among friends
[03:09:16] <Tom_itx> wonder if he takes paypal
[03:09:32] <r00t-Shed> on ebay
[03:09:47] <r00t-Shed> curtis
[03:09:52] <r00t-Shed> its his buddy
[03:09:52] <Tom_itx> he does
[03:10:06] <r00t-Shed> they email you the code
[03:10:16] <Tom_itx> will it carve metal?
[03:10:18] <r00t-Shed> and msg u it on ebay
[03:10:23] <Tom_itx> i suppose you can adjust the feed speed
[03:10:25] <r00t-Shed> it dont care
[03:10:33] <r00t-Shed> feedspeed depth
[03:10:37] <r00t-Shed> you can try it for free
[03:10:50] <Tom_itx> meh i'm not gonna waste my time on a watermark
[03:10:51] <r00t-Shed> but it puts a line corner to corner, watermark, in your carving
[03:11:13] <r00t-Shed> you can mess with it though before you buy
[03:11:30] <Tom_itx> does it let you choose a cutter size?
[03:11:32] <r00t-Shed> and he dont care how many computers you put it on
[03:11:51] <Tom_itx> good, send it to me :)
[03:11:55] <Tom_itx> kidding of course
[03:12:04] <r00t-Shed> you choose the stepover
[03:12:17] <Tom_itx> what stepover do you use?
[03:12:20] <Tom_itx> .010 or so?
[03:12:22] <r00t-Shed> you determine the step over by the size of your bit
[03:12:51] <Tom_itx> you use a pointed bit?
[03:12:57] <r00t-Shed> all kinds
[03:13:09] <r00t-Shed> mostly ballends
[03:13:17] <Tom_itx> what diameter?
[03:13:22] <Tom_itx> 1/8"
[03:13:22] <r00t-Shed> 1/16
[03:13:24] <Tom_itx> k
[03:13:38] <Tom_itx> i'm not sure i can get ballnose that small locally
[03:14:10] <r00t-Shed> ebay
[03:14:41] <Tom_itx> how long does it take to get the code?
[03:14:43] <r00t-Shed> i also use 1/16 carbide plunge tips
[03:14:51] <r00t-Shed> v bits
[03:15:04] <Tom_itx> i have some .032 em
[03:15:11] <r00t-Shed> vbit and low stepover = mad detail
[03:15:12] <Tom_itx> and some tiny ones
[03:15:43] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/etching/mills1.jpg
[03:15:50] <r00t-Shed> "I usually do a roughing pass with 1/8" ball nose and 15-20% stepover then a finishing pass with a 1/16" ball nose with a 7-10% step over."
[03:15:53] <r00t-Shed> from another users
[03:15:56] <Tom_itx> i think the small one is .015"
[03:15:58] <Tom_itx> i forget now
[03:16:43] <r00t-Shed> "If so you can do even better with ball-nose bits with a stepover of 7-9% of the cutter width."
[03:16:48] <r00t-Shed> diff user
[03:17:00] <r00t-Shed> same q, wtf to use for bits
[03:18:24] <Tom_itx> what do you do, download the file then get the key via email?
[03:18:44] <r00t-Shed> yeah
[03:18:55] <r00t-Shed> they also msg u on ebay
[03:19:04] <r00t-Shed> did you buy it?
[03:19:09] <Tom_itx> no
[03:19:22] <Tom_itx> i have cad cam but i may just for something to play with
[03:19:34] <r00t-Shed> its super easy
[03:19:50] <r00t-Shed> you can do your face or nutsack
[03:19:53] <r00t-Shed> just take a pic !
[03:20:05] <Tom_itx> i'll pass on that
[03:20:22] <r00t-Shed> do your sack and give it to your mom for xmas
[03:21:22] <Tom_itx> leave her out of it, she's not with us anymore
[03:22:02] <r00t-Shed> certainly you knew i was kidding
[03:22:21] <Tom_itx> still, you should have some tact on irc

[05:11:51] <r00t-Shed> no
[05:11:59] <r00t-Shed> i will have to later
[05:12:00] <tjb1> It explains it all in 20 seconds
[05:12:20] <tjb1> center punch on linear rail beside plasma torch connected to air cylinder
[05:12:26] <tjb1> fire to mark holes, etc...
[05:12:42] <r00t-Shed> oh
[05:13:21] <tjb1> Ill go ahead and buy the cylinder if I win the auction on this 7" rail
[05:13:35] <tjb1> I bought a 4" iko rail for the plasma torch for the initial height sensing
[05:13:48] <tjb1> Going to use a microswitch instead of the ohmic sensing
[05:14:01] <tjb1> http://www.ebay.com/itm/200747300054?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649#ht_1772wt_1472
[05:14:32] <tjb1> Put 2 springs to hold the torch down, drive it down until it trips switch and then back up pierce height
[05:14:56] <tjb1> I read about the ohmic hitting areas that might not be conductive and it got me worried so im going with the soft touch and switch
[05:19:00] <tjb1> I guess for that to work it would have to know how far travel is until switch without stock in it
[05:19:36] <r00t-Shed> good thing i have no clue what your talking about.
[05:19:43] <r00t-Shed> :)
[05:20:13] <tjb1> not many plasma people in here is there
[05:20:22] <r00t-Shed> not atm
[05:20:27] <r00t-Shed> well not awake
[05:21:10] <tjb1> ill draw this part on when i have it in my hand
[05:22:13] <tjb1> Ah wish I didnt have to waste time on native american history...

[13:56:02] <Jymmm> 120 racks
[13:56:23] <joe9> http://codepad.org/AGkDr5nW any thoughts on this error? http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Following_Error says that it is a .ini file error. but, even after changing the ini file, I am not able to figure it out.
[13:56:42] <joe9> error message: "joint 0 following error"
[13:56:44] <jdh> the local community college has a sketchup class. It was very informative and I became proficient, but stopped using it.
[13:57:34] <skunkworks> joe9, can you post your ini?
[13:57:47] <joe9> skunkworks: sure.
[13:58:07] <skunkworks> usually it is that you do not have enough headroom between the stepgen accelleratoin and the joint accelleration
[13:58:18] <joe9> http://codepad.org/ORru0HPx skunkworks.
[13:58:44] <skunkworks> hal?
[13:59:06] <jdh> joe9:did you recently change any config options?
[13:59:12] <joe9> http://codepad.org/LT7yaOSV .hal file
[13:59:41] <joe9> http://codepad.org/KK6AqtLs custom.hal file
[13:59:46] <joe9> skunkworks, ^^
[14:00:01] <joe9> jdh: yes, I was trying to increase the base period setting
[14:00:07] <joe9> from 25000 to 28000
[14:00:09] <jdh> increase or decrease?
[14:00:24] <joe9> as at 25000, I was getting the RTAPI error.
[14:00:40] <joe9> jdh: increased it from 25000 -> 28000
[14:01:01] <joe9> first tried 50000, same joint error, then tried 28000
[14:01:07] <jdh> sounds like your step rate is too high for that base period
[14:01:14] <skunkworks> when do you get the folloing error? moving at high speed?
[14:01:26] <skunkworks> (agreeing with jdh )
[14:01:28] <joe9> skunkworks: while "Home all"
[14:01:40] <joe9> skunkworks: it homes z-axis and y-axis fine
[14:01:57] <joe9> when it is homing the x-axis, it finishes the homing and just before stopping, it gives that error.
[14:02:56] <skunkworks> because it rapids to the actual home position I would guess...
[14:03:24] <skunkworks> HOME_OFFSET = 12.000
[14:03:37] <skunkworks> lower your max velocity
[14:03:49] <jdh> drop vel/accel a bit and see if it goes away
[14:04:48] <skunkworks> 40000 scale is quite high - that is going to limit your max velocity with software step generation
[14:04:49] <joe9> on just the x-axis or both the x and y axes?
[14:04:57] <jdh> X first
[14:05:05] <jdh> then see if the error moves to joint 2
[14:05:07] <joe9> skunkworks: how do I find the "correct" scale?
[14:05:16] <skunkworks> I am going to guess on all - as your scale is the same for all axis.
[14:05:19] <jdh> same velocity though so i tshoudl show up there
[14:05:20] <r00t4rd3d> is an "over head gantry" one that moves
[14:05:54] <joe9> I use the gecko g540 and KL23H276-30-8B.pdf
[14:05:56] <r00t4rd3d> i hate when i have to ask dumb questions
[14:05:59] <joe9> with a taig machine.
[14:06:10] <jdh> you slowed your base period 11%, I'd try kocking that much off max vel
[14:06:18] <joe9> ok, thanks.
[14:06:38] <jdh> joe9: or get a mesa 5i25
[14:06:52] <joe9> jdh: my max velocity is 0.95. do you still think it is a bit high?
[14:06:59] <skunkworks> I don't think you can change the microstepping on the geckos.. So you are stuck
[14:07:08] <joe9> with the step rate, it is ending up to be high. -- you mean?
[14:07:27] <jdh> yoru scale is what it is. You have to work within that limit
[14:07:31] <skunkworks> try .8 for all axis
[14:07:49] <jdh> or do the math
[14:08:04] <skunkworks> you could bump that up until you start getting following errors again. If I was more energetic - we could do the math.
[14:08:05] <jdh> but. .8 should work.
[14:08:06] <skunkworks> heh
[14:08:56] <joe9> skunkworks: ok, doing that. Thanks.
[14:09:03] <skunkworks> let us know
[14:09:38] <skunkworks> but yes - investing in a 5i25 would let you go as fast as the mechanics would allow
[14:09:54] <joe9> btw, the comment character for the .ini file. is it # or ;? it seems to be #, according to what is generated?
[14:09:55] <jdh> 5i25 will get rid of the following error and the rtapi
[14:10:22] <joe9> what is 5i25? let me google that? another hardware piece?
[14:10:45] <jdh> mesanet pci card. You can plug your g540 straight in to it
[14:10:57] <jdh> and it has another port for additional IO
[14:11:30] <skunkworks> plus you can get daughter boards that do a ton more
[14:11:38] <joe9> cool, 0.85 -- no error.
[14:11:50] <anonimas1> it's the best thing I ever bought for my setup :)
[14:12:08] <skunkworks> Great and great ;)
[14:12:46] <joe9> how much is it? where did you get it from? that seems to be a cool idea? does that mean I can put the cnc on any machine? or, does it still have to be within the latency principles?
[14:13:02] <anonimas1> mesanet.com
[14:13:18] <jdh> $90ish
[14:13:20] <anonimas1> it means you can push your hardware to as fast as your motors will allow
[14:13:25] <joe9> anonimas1: thanks, will check up on it.
[14:13:38] <anonimas1> i think most people here went with that kind of setup
[14:13:43] <skunkworks> joe9, your max_linear_veilocity in the traj section should be 1.5
[14:14:03] <jdh> I got a 7i43, before 5i25 came out :(
[14:14:10] <anonimas1> it pretty much means unlimited step rates(also you can stick your microstepping on max and still reach max speed)
[14:14:14] <skunkworks> sqr(.85^2+.85^2+.85^2)
[14:14:35] <Jymmm> 50,000 microstep
[14:14:45] <jdh> zero torque
[14:14:47] <joe9> anonimas1: does the pc need to have decent latency figures?

[14:15:37] <skunkworks> It still shoudl be 'good' - I would say less than 50us

[15:03:45] <skunkworks> Some day I am going to have a 4th axis
[15:03:55] <skunkworks> (one that isn't just an indexer)
[15:04:00] <FredrikHson> this was actually really simple
[15:04:40] <FredrikHson> got an old kuka robot that we didn't use for anything so stole the harmonic drive from that and just mounted a stepper on the back of it
[15:05:04] <skunkworks> nice!
[15:05:31] <FredrikHson> well and a block of iron since the almuminum casing for the drive wasn't exactly sawed of with great accuracy ;)

[15:13:43] <FredrikHson> its a bit long tbh especially with the chuck mounted but better than my old hand cranked one ;)

[15:13:50] <syyl> and when you are there to pick up the robot arm
[15:14:06] <syyl> you just pull out a sabre saw and cut of the joints
[15:14:14] <syyl> "you can keep the rest"
[15:14:36] <FredrikHson> still got a bunch of those drives leftover but most are not as neat since they are encased in a huge cylinder of iron

[16:12:29] <Jymmm> (provisoning)
[16:13:09] <Connor> No. Bellsouth brought in 23" rack.. Broke out the T3, the ATM and used the 3rd T3 for the T1's.
[16:13:47] <Connor> feed them into a rj45-X panel that was installed in my wire rack.. and I could patch into them.
[16:14:16] <Jymmm> not cabling, provisioning.

[16:15:38] <Connor> Yea. and Dialup.
[16:15:46] <Jymmm> lol
[16:15:58] <Connor> and the ATM was for DSL

[18:00:19] <JessicaRN> any way to check the parport easily?
[18:00:59] <IchGuckLive> JessicaRN: does it loead a Simulation mashine
[18:01:07] <IchGuckLive> in the sim folder ?
[18:01:39] <IchGuckLive> what version is displayed at the startup
[18:01:55] <JessicaRN> no, doesn't seem to. I click on the EMC2 icon and a get the splash screen. then, a second later, i get the error dump
[18:02:20] <IchGuckLive> please load from menue not the icon
[18:02:34] <IchGuckLive> application cnc
[18:02:38] <JessicaRN> ver 2.2.5 according to the error dump
[18:02:48] <IchGuckLive> oh way back
[18:02:59] <IchGuckLive> we are working on 2.6
[18:03:11] <pcw_home> ancient history
[18:03:18] <IchGuckLive> 2.5 is standard and 2.4 is the recomendet
[18:03:32] <JessicaRN> the box has been in storage for like 3 years, so no surprise there
[18:03:58] <IchGuckLive> we had 2.3.5 3 years ago
[18:04:17] <JessicaRN> i opened up the app from the menu and then selected the config. after, i get the same think as before
[18:04:31] <IchGuckLive> i dont think anyone is able to get beond your error
[18:04:56] <JessicaRN> cool... I'll rig up a net connection and d/l the newer emc
[18:05:23] <IchGuckLive> i think there is simply no RTI kernal running
[18:05:50] <IchGuckLive> JessicaRN: where are you from the USA

[18:06:24] <IchGuckLive> so im off thrue to time
[18:07:04] <JessicaRN> while I have you all here, can anyone offer suggestions for good, free stl->toolpath generators
[18:07:05] <IchGuckLive> JessicaRN: http://buildbot.linuxcnc.org/ is today ofline
[18:07:43] <JessicaRN> shite, so when will it be back up?
[18:08:12] <pcw_home> just download the 2.5 ISO
[18:08:18] <IchGuckLive> just checking that
[18:08:47] <IchGuckLive> JessicaRN: is it a standard 3 axis mashine
[18:09:22] <JessicaRN> yeah
[18:09:25] <IchGuckLive> and what os are you on
[18:09:27] <JessicaRN> it's a fireball v90

[18:10:03] <JessicaRN> dunno which ver
[18:10:21] <andypugh> Is there anything on that machine that you want to keep?
[18:10:26] <IchGuckLive> so i guess if you like i woudt go with your box to ubuntu 10.04 and linuxcnc 2.5

[18:20:35] <tjb1> One is for people that know all about computers and linux
[18:20:52] <jdh> I disagree with that statement.
[18:21:18] <tjb1> You need a pretty strong grasp of linux to use linuxcnc
[18:21:27] <tjb1> Well not use it…to do more than just use it
[18:21:37] <JessicaRN> actually, from an informed and intelligent audience, I would hope to get and informed and thoughful response. we're not fundimentalists, are we?

[18:26:02] <alex4nder> it works great.
[18:26:06] <JessicaRN> see, that is an extremists statement. if you feed g-code to either tool they will run a mill. there is not -that- much difference. and, if there is, please just offer some points to support your statement. that's all i'm asking for.
[18:26:14] <alex4nder> and sometimes drills holes in your mill-table on accident.
[18:26:30] <archivist> emc can do whatever you want, may need to think a bit though

[18:27:24] <JessicaRN> are you a republican just cuz your dad told you to vote that way?
[18:27:33] <JessicaRN> or do you make your own decisions?
[18:27:43] <archivist> JessicaRN, you can extend emc, make your own kins for special machines etc
[18:27:43] <alex4nder> well I'd start by learning about politics.
[18:27:47] <JessicaRN> I'm asking for an informed and intelligent argument
[18:28:01] <alex4nder> JessicaRN: there's no argument.. go use Mach3 if you want
[18:28:19] <jdh> if mach does all you need, then it doesn't really matter.
[18:28:21] <JessicaRN> and, alex, I'm asking you about the pros and cons of emc vs mach3. I'm trying to become informed.
[18:28:28] <archivist> it has realtime feedback so is a better machine control
[18:28:53] <JessicaRN> archivist: thank you. finally, a data point
[18:28:57] <alex4nder> JessicaRN: if this were religious, I think most of LinuxCNC users would be buddhists.
[18:29:01] <jdh> it has closed look control
[18:29:03] <pcw_home> Yeah IMHO LinuxCNC is flexible, open, powerful but not terribly polished Mach is commercial/closed windows only ,fairly polished
[18:29:05] <pcw_home> LinuxCNC make a lot of the real time guts available for extension, Mach has only minimal reall time capabilities (just the software step generation I believe)
[18:29:47] <JessicaRN> thank you again... that is the kind of thing I was asking for.
[18:30:00] <alex4nder> do you even understand what any of that means?
[18:30:06] <JessicaRN> how stable is the current EMC compared to mach?
[18:30:22] <archivist> emc can drive up to 9 axes at the same time

[18:33:21] <jdh> this sounds like most #linux windows conversations of the last 20 years
[18:33:27] <alex4nder> haha
[18:34:18] <JessicaRN> actually, a conversation would be nice. I wasn't asking about linux vs windows. I was asking about two specific apps
[18:34:31] <jdh> it's pretty much the same conversation though
[18:34:41] <jdh> for about the same reasons
[18:34:47] <pcw_home> Because Mach depends on external hardware for real time (beyond simple step generation)
[18:34:49] <pcw_home> advanced function like rigid taping and threading are interface hardware dependent
[18:34:51] <pcw_home> (the hardware must handle the synchronization)
[18:34:52] <pcw_home> LinuxCNC does all these advance functions in real time software so they work with any interface hardware (in the same way)

[18:36:48] <JessicaRN> with a simple mill like the fireballl, it has minimal feedback. really all it has is limit switches. so, that is a strength in some environments, but not in this one. correct?
[18:36:54] <jdh> linux and/or linuxcnc is technically superior, windows and/or mach3 is prettier and arguably easier to use
[18:37:46] <JessicaRN> I agree, jdh, but there is a point you forget. linux support tends to suck.
[18:37:49] <jdh> for a router like that, I don't think either of them is inherently better.
[18:38:09] <jdh> I would disagree with that also.
[18:38:36] <jdh> linuxcnc support is exceptional IMO
[18:38:40] <alex4nder> yup

[18:38:44] <pcw_home> Yes on a simple mill and if you dont want to do rigid tapping of other fancy things I think its a tossup But I do think Linux is less likely to break itself than windows
[18:38:47] <JessicaRN> with a commercial product like mach, the publisher has to support it or they get a bad rep. for EMC, I'll need to ask help from the likes of alex... ugh!
[18:39:09] <JessicaRN> pcw_home: without a doubt
[18:39:17] <JessicaRN> linux is MUCH more stable
[18:39:24] <pcw_home> Actually I think LinuxCNCs support is top notch (see the forum)
[18:39:33] <alex4nder> JessicaRN: you've been SANing and WANing for 20 years, you'll have this software on lock-down in no time.
[18:39:41] <alex4nder> I'm surprised you're even asking questions.

[18:41:03] <alex4nder> if I had pigtails, you'd be pulling them.
[18:41:07] <JessicaRN> linux is much more reliable than windows

[18:41:31] <r00t4rd3d> i dont

[18:42:44] <jdh> as I said, religino is a better conversation
[18:42:53] <r00t4rd3d> tjb1, nothing worth taking a picture of
[18:42:55] <JessicaRN> any good tools for STL>toolpath?
[18:43:12] <jdh> windows definitely wins for CAM
[18:43:23] <tjb1> The map is pretty cool
[18:43:49] <JT-Shop> OneCNC is getting better
[18:44:16] <andypugh> One advantage of LinuxCNC is that if it doesn't have a feature you want you don't have to persuade the developer to add it for you, you can add it yourself, or get any other programmer to do it for you.
[18:44:17] <JessicaRN> Well, I can create the gcode on anything and just send it over to the machine that runs the mill. so platform is irrelevant
[18:44:49] <JessicaRN> OneCNC?
[18:45:01] <JT-Shop> cam program
[18:45:07] <andypugh> LinuxCNC is also rather more modular, For example you can use only the HAL layer to do simple things like driving steppers.
[18:45:10] <jdh> from the early 80's
[18:45:43] <JessicaRN> any decent freeware?
[18:46:02] <JT-Shop> no
[18:46:28] <JessicaRN> what about the rhino free offering? worth looking at?
[18:47:19] <jdh> depends on what you want to cut. There might be suitable free tools depending on complexity. Or write the code by hand.
[18:47:40] <JessicaRN> it might all be irrelevant. I may be getting bobcam for free. never used it, but it gets decent reviews
[18:48:20] <JT-Shop> all those reviews are from bobcad sales people LOL

[18:53:59] <pcw_home> A little off topic but I also think LinuxCNC would be really good in an educational or research

[19:38:04] <pcw_home> (that is is you have 30 usec worst case latency you wait for up to 30 usec and remove the jitter)

[20:10:04] <Tom_itx> andypugh i'd venture a guess of 8 or 10"
[20:10:18] <tjb1> oooh i got sniped lol
[20:10:32] <Tom_itx> based on the fact the square hole is probably 1/2 or 5/8"
[20:10:48] <JT-Shop> andypugh: can you scale it by the leaf?

[20:11:43] <andypugh> Normally dividing heads have the chuck on a spindle, and are a little flexible.
[20:11:58] <andypugh> I figure I could use the jaw-slots as T-slots for general workholding
[20:12:35] <andypugh> It's badly advertised. I like badly-advertised

[20:17:18] <archivist> about same distance for me or andy to drive to it, Im may be a bit nearer, may even get a payed for trip past it
[20:17:29] <andypugh> And strapping that to the back of my bike would be a challenge.

[20:26:44] <andypugh> I have not owned a honda 50. I had a Puch 50, and a Honda 100
[20:27:02] <andypugh> For some reason I preferrd the Pugh 50 to the Honda. :-)
[20:27:07] <JT-Shop> the honda 50 super sport was my first bike
[20:27:22] <cradek> it would go 50mph which was good because it let you get out in front of all the blue smoke
[20:27:28] <JT-Shop> I proptly broke the tail light doing a wheele in the school yard
[20:27:51] <cradek> the kick starter didn't work so I had to push it every time

[21:58:51] <andypugh> I maninly don't
[21:59:24] <Tom_itx> JT-Shop uses ngcgui
[21:59:31] <andypugh> Both JT and myself (and probably others) tend to use subroutines.
[21:59:37] <Tom_itx> it's installable within linuxcnc
[21:59:46] <andypugh> For one-offs it's simpler.
[21:59:58] <Tom_itx> i agree on the lathe
[22:00:10] <Tom_itx> we did most of our lathe stuff mdi then saved it
[22:00:22] <andypugh> This is my Lathe screen: http://www.bodgesoc.org/lathe/lathe.html
[22:00:49] <andypugh> I just dial in target X and Z, cut and feed, and press the button for the operation I want.
[22:00:58] <andypugh> It works a treat for one-offs.
[22:01:02] <Jymmm> andypugh: You made a shoot em up module?
[22:02:40] <andypugh> What I want to do is the same thing as tabs. Each tab has a picture of the op, with dimensions you can type in, then press the button.
[22:02:59] <Tom_itx> nice
[22:03:20] <andypugh> Partly because I tend to forget details like whether thread depth is diameter or radius, or where the chamfer/radius ops start from.
[22:04:00] <andypugh> But I have other things to do first.

[23:29:02] <andypugh> The bash script called would just halcmd setp pwmgen.1.value 3000
[23:29:40] <andypugh> Sorry, probably halcmd setp pwmgen.%1.value $2
[23:30:12] <andypugh> (with the correct syntax to actually work, bash scripting is an unopened book to me)
[23:32:30] <Nick001-Shop> using a 2000 line encoder on that spindle - can linuxcnc handle that directly or would I need to use a mesa like card
[23:33:13] <andypugh> Nick001-Shop: It can handle it directly. At low speed
[23:33:36] <Nick001-Shop> like how slow?
[23:33:39] <andypugh> By low, I mean hundreds of rpms
[23:34:21] <Nick001-Shop> ouch - need 900-2000 rpm from each spindle
[23:35:05] <Nick001-Shop> tapping would be at 600 - 1200 rpm
[23:36:02] <cpresser> 600 rpm = 10rps = 20k pulses/sec that might be to fast for the parallel-port
[23:36:15] <andypugh> 2000 rpm * 8000 counts / 60 seconds is 250kHz. That's well into Mesa/Pico territory. No choice.

[23:37:50] <Nick001-Shop> what mesa cards would i need to do this? 8 spindles on 8 slides and 1 rotary positioning spindle
[23:38:07] <andypugh> Servo or Stepper?
[23:38:20] <Nick001-Shop> servos
[23:38:46] <Nick001-Shop> just dc motors with encoders
[23:40:21] <andypugh> Probably a 5i23 and two 7i48s. But a 5i25 and two 7i77s is an option. You might even manage with 5i23 and one 7i65
[23:41:00] <andypugh> Ah, hang on, you need 16 analogue voltages?
[23:41:15] <andypugh> (8 servos and 8 spindles)
[23:41:31] <Nick001-Shop> what will do the best job - only slightly cost conscience
[23:42:11] <andypugh> How will you drive the spindles? Anlogue to VFD?
[23:42:22] <andypugh> What type of motor?
[23:42:54] <Nick001-Shop> dc motors - 24vdc 1.8 amps
[23:43:03] <andypugh> That's the spindles?
[23:43:38] <Nick001-Shop> Per unit has 1 spindle and 1 moter driving a ballscrew
[23:44:12] <Nick001-Shop> 8 units and 1 rotating or indexing spindle
[23:44:55] <Nick001-Shop> each spindle has its own drive motor
[23:45:17] <andypugh> In total, how many DC motors (DC brushed, DC brushless, Induction) at what voltage and current, how many encoders and how much IO?
[23:46:14] <andypugh> Bear in mind I don't work for or have any special knowledge about Mesa kit. I just know what I have picked up here and using the stuff that I have.
[23:49:48] -!- rob_h has quit [Ping timeout: 248 seconds]
[23:53:52] <Nick001-Shop> 17 motors total , 17 total encoders - motors 16 about 24vdc @ 2 amps - 1 larger motor for the indexer
[23:54:52] <Nick001-Shop> possibly a brake for the indexer to hold position
[23:57:45] <Nick001-Shop> I'm going with brushed motors for now because they're plentiful
