Back
[00:01:34] <Thetawaves> 2.6.30.5 is what you have
[00:01:45] <pfred1> ah
[00:01:57] <pfred1> yes might not work then
[00:02:32] <pfred1> though with that systme was X that was the issue not the kernel itself
[00:02:50] <pfred1> I htink whatever Lenny came with stock was in fact new enough for that GPU
[00:05:22] <Thetawaves> i just don't want to run any old linux
[00:05:54] <pfred1> and what you want matters why?
[00:06:27] <Thetawaves> what's the point in running an end of life linux? getting newer software is usually a bitch
[00:06:37] <Thetawaves> this openssh-server issue is a perfect example
[00:06:40] <pfred1> because it works?
[00:06:52] <Thetawaves> that's the problem, it doesn't
[00:07:06] <pfred1> well I set it all up some time ago now maybe since then they've released something new
[00:07:12] <pfred1> it works here
[00:07:23] <Thetawaves> right, that's when it works
[00:07:43] <Thetawaves> you set it up and don't need to make any real changes
[00:07:51] <pfred1> I don't?
[00:08:08] <Thetawaves> after you've got the system setup?
[00:08:38] <pfred1> in case you're unaware I had to make a few changes in order to do that
[00:09:32] <Thetawaves> i think ubuntu just sucks
[00:09:33] <pfred1> why can't you get rid of the ssh and just install the one you want?
[00:09:48] <Thetawaves> and the package manager gets conflicts very easy on slightly older releases
[00:09:49] <pfred1> well that is why I set it up to work on Debian
[00:10:14] <pfred1> ubuntu makes me queasy
[00:12:13] <Thetawaves> this is mostly the reason i appreciated slackware... no complex package manager to get conflicted
[00:12:15] <pfred1> but I have to say I'm not completely enamored with the latest version of Debian
[00:12:30] <pfred1> oh package management rules
[00:12:53] <pfred1> having to deal with every dependency by hand is a nightmare
[00:13:06] <pfred1> been there, done that!
[00:13:15] <Thetawaves> results in a much more stable system
[00:13:17] <Thetawaves> in my opinion
[00:13:50] <pfred1> well then you obviously think you are more talented than thousands of experts
[00:14:24] <Thetawaves> are you sure?
[00:14:34] <psha> pfred1: +1
[00:14:48] <pfred1> I'm good but I'm suffering from no illusions
[00:15:23] <psha> already been there, debian based package system is very good and provides much batter results then trying to handle each dep by hand
[00:15:33] <pfred1> nah man I've dealt with Linux long enough to know it is more than I want to deal with
[00:15:42] <Thetawaves> slackware has always had a reputation for being more stable and reliable than debian.
[00:15:47] <psha> but as any instrument you have to know how to work with it to get fine results
[00:16:21] <psha> what is 'stable'?
[00:16:30] <pfred1> I don't know if slack has a rep for being more stable than Debian more static possibly
[00:17:01] <Thetawaves> once you setup slackware, it will run forever
[00:17:20] <Thetawaves> the security updates are very thoroughly tested
[00:17:24] <pfred1> what Linux dostro won't?
[00:17:32] <Thetawaves> and software is not unnecessarily updated
[00:17:55] <Thetawaves> except on major releases of course
[00:17:57] <pfred1> I ran suse once for 8 years until thecaps let go on the mobo then popped that HDD out slapped it into a new system and it still ran!
[00:18:57] <pfred1> it was kind of a good thing that system blew up on me or I'd still be running it
[00:19:49] <pfred1> but when I moved it to a new system I wanted to update some parts of it and by hten it simply wasn't possible
[00:20:46] <pfred1> in that time SuSE had changed to SUSE and actually changed hands so I don't blame them for dropping support
[00:21:03] <pfred1> it was time to move on ...
[00:21:34] <pfred1> Thetawaves I been running Linux for about twice as long as you have so ah
[00:21:45] <pfred1> just who do you think you're fooling?
[00:22:03] <pfred1> I was done with slack before you even ran it
[00:22:10] <psha> Thetawaves: same you may say about debian
[00:22:35] <psha> security and *-updates are tested and there is no much packages
[00:22:37] <Thetawaves> i had conflict with the tex library in debian
[00:22:42] <psha> you may even drop *-updates repo
[00:22:46] <pfred1> debian's package manager is the single most widely used piece of software associated with Linux behind the kernel itself
[00:22:50] <Thetawaves> a tex library*
[00:22:57] <psha> if you have conflicts then you are trying to install it from invalid repo
[00:23:06] <Thetawaves> what
[00:23:12] <psha> if you are stuck with stable release then it won't happen
[00:23:24] <Thetawaves> it has happened to me
[00:23:37] <Thetawaves> on etch
[00:24:24] <pfred1> Thetawaves you ever try to build tex from source?
[00:24:28] <psha> with etch repository and etch install?
[00:24:53] <Thetawaves> psha, yep
[00:25:01] <Thetawaves> pfred1, i've heard horror stories
[00:25:14] <pfred1> yeah tex is some pretty involved stuff
[00:25:26] <pfred1> I mean like those with IQs under 200 need not apply
[00:25:51] * pfred1 misses the mark by about 5 points
[00:26:05] <pfred1> and it makes me feel like a monkey!
[00:26:32] <pfred1> so it comes as no surprise to me that you might have run into a glitch or two there
[00:26:38] <psha> Thetawaves: i'm upgrading tex (from tetex to texlive to ...) on system starting from woody and don't remember any serious difficulties...
[00:27:10] <pfred1> psha really delve into tex it is like particle physics
[00:27:41] <pfred1> it is pretty much made by physicists for physicists
[00:28:01] <pfred1> the stuff is brutal!
[00:28:10] <psha> not trivial yea )
[00:28:29] <psha> dealing with it for a long time and still confused by some parts...
[00:28:41] <pfred1> donald is way out there
[00:29:33] <pfred1> I'm not saying debian is perfect but it does a beter job than I am willing to do today
[00:29:54] <pfred1> the little snags I can deal with better than if I was to try to go it alone
[00:30:38] <pfred1> I juggled slack deps for years and it was a full time job
[00:30:41] <Thetawaves> slackware provides a good base system with all that stuff... then i would setup all my cnc stuff... and then the system would just work
[00:30:54] <Thetawaves> until i rebuild the whole system in two years using the latest release of slackware
[00:31:08] <pfred1> why would you do that?
[00:31:17] <pfred1> once it works it works
[00:31:40] <Thetawaves> yeahhhhh
[00:31:51] <Thetawaves> maybe there will be 'new' software available by then
[00:32:25] <pfred1> there is new software available today don't mean I'm running right out to get it though
[00:32:33] <Thetawaves> i guess i'm trolling
[00:32:41] <Thetawaves> because i already downloaded the debian iso
[00:32:46] <Thetawaves> :)
[00:32:54] <pfred1> I got done chasing the latest and the greatest a long time ago
[00:32:59] <pfred1> get tiring
[00:33:41] <pfred1> honestly I liked Linux years ago and I'm not too thrilled about every new change i see
[00:34:01] <pfred1> grub2 sux
[00:34:20] <pfred1> I see no advantage to it for me at all
[00:34:43] <Thetawaves> dude... have you ever heard of plymouth?
[00:34:48] <Thetawaves> i tried to uninstall it
[00:34:57] <pfred1> it is like a dodge for poor folks isn't it?
[00:35:04] <Thetawaves> apt-get wanted me to say "Yes, do as I say!"
[00:35:05] <Thetawaves> exactly
[00:35:16] <Thetawaves> because it would have uninstalled everything
[00:35:47] <Thetawaves> it is just the boot up splash screen!
[00:35:50] <Thetawaves> i couldn't believe it
[00:36:39] <pfred1> did you file a bug report?
[00:37:58] <Thetawaves> lol
[00:38:06] <pfred1> what is funny?
[00:38:07] <Thetawaves> ruddy ubuntu
[00:38:50] <Thetawaves> ubuntu people don't want to know about how difficult it is to uninstall their gui candy
[00:39:04] <Thetawaves> they would be like bug -- closed (bug filer is a sucker)
[00:39:22] <pfred1> so you're saying that you didn't then?
[00:39:29] <Thetawaves> nope
[00:39:36] <pfred1> OK then don't complain
[00:56:52] <AitalMAC> With EMC can i in some way store the time a machine has been working?
[00:57:28] <psha> working = uptime or working = tool is moving?
[00:58:19] <pfred1> AitalMAC you can preface any command with time
[00:58:53] <pfred1> time - run programs and summarize system resource usage
[00:59:13] <pfred1> man time
[01:01:48] * pfred1 has run Linux a little too long ...
[01:12:03] <pfred1> to figure out how much a machine moves a step you multiply steps per rev by lead by microstepping mode then take that number and divide it into 1 right?
[01:13:49] * pfred1 needs looser leads
[01:14:13] <pfred1> 0.00000625 a step seems a tad excessive to me
[01:14:54] <AitalMAC> Just how many hours the spindle has turn for example
[01:16:05] <AitalMAC> i think that if machine moves rapidly it does not count as the machine working, for a plasma it would be how long time you keep the fire on
[01:17:28] <AitalMAC> The interpreter can calculate an approximate time for a G-Code to complete?
[01:21:21] <AitalMAC> I could get time component to go on with the spindle, is the time saved somewhere?
[01:22:58] <psha> no, you must save it somewhere yourself
[02:17:25] <DJ9DJ> moin
[05:10:16] <Rogue_> hi
[05:26:07] * jthornton has big bubbles and lots of foam this morning
[05:41:02] <jthornton> with a 50,000ns base period how fast can you count pulses from an encoder?
[05:48:26] <Mjolinor> it is sunday morning, that is certainly a tuesday calculation, its the only time the brain is working suffuciently well
[05:49:41] <jthornton> at least your brain works well enough to calculate that on Tuesday :)
[05:52:24] <jthornton> ok, an easy question how many ticks of the base period is needed to count a pulse?
[06:00:08] <Mjolinor> not easy enough, things like "what is the temperature outside" or " is the sun shining" are suitable questions for sunday morning
[06:02:31] <jthornton> ok, when will my Hefeweizen be done with primary fermentation?
[06:07:26] <alex_joni> jthornton: 1/50.000ns = 20kHz
[06:07:39] <alex_joni> that means you want about half to be reliable
[06:07:44] <alex_joni> so about 10kHz
[06:07:55] <alex_joni> on a 1024 encoder that's about 10 turns/second
[06:08:05] <alex_joni> but as Mjolinor said, it's sunday here ;)
[06:08:43] <Mjolinor> so it being sunday please calculate the probability that the above iinformation is incorrect
[06:09:45] <alex_joni> it's 7 to 1
[06:09:49] <jthornton> but it is Sunday at lunch for you Alex
[06:10:49] <jthornton> so to be reliable you need two ticks of the base thread per pulse?
[06:59:01] <Loetmichel> mornin'
[06:59:23] <Mjolinor> does anyone hsere use PCB. I cannot get a drill mask fomr the goddam thing
[07:30:20] <mazafaka> morning
[07:31:41] <mazafaka> we were cutting the frame of the motorcycle and weld it with my buddy. So the second motorcycle is about to appear.
[07:32:07] <jthornton> cool
[07:34:16] <mazafaka> And then, I will finish the walls' finishing and order an airbrush, invite another buddy to create a shop of airbrushing
[07:36:23] <mazafaka> I want to buy a JAS 1119 airbrush
[08:04:02] <mrsun> hmm, 20mA max out on V+ pin ...
[08:59:08] <mrsun> hmm, opamps, this one says Vcc and Vcc+ .... it can be run as single supply, would i connect Vcc to gnd or Vcc+ to gnd? :P
[09:07:33] <archivist> mrsun, /me would read the datasheet for example connections, but sounds wrong
[09:21:19] <mrsun> archivist, there is no example connections in the datasheet
[09:21:36] <mrsun> on the other package type they have they have named them Vcc+ and GND
[09:21:42] <mrsun> but on DIP8 its Vcc and Vcc+
[09:22:18] <mrsun> ahh there, in another datasheet i found its called Vcc- and Vcc+
[09:32:57] <jthornton> http://imagebin.org/200890
[09:35:27] <mrsun> something good brewing? :)
[09:39:34] <jthornton> Hefeweizen
[09:40:07] <Mjolinor> OMG, they mated and made a little one :o
[09:46:58] <jthornton> yea, all over the floor of the fermentation chamber\
[11:23:40] <A2Sheds> will that be beer or whiskey someday?
[11:23:57] <JT-Shop> BEER
[11:24:37] <JT-Shop> technically it is beer today with a very high SG...
[11:57:25] <anonimas1> does anyone have clue of feeds and speeds of copper
[11:57:36] <anonimas1> err for..
[11:57:40] <anonimas1> a 2mm drill...
[11:59:29] <anonimas1> Tom_L: got any clue how to drill copper successfully?
[12:02:02] <Tom_itx> haha
[12:02:07] <Tom_itx> sharp tools
[12:02:18] <Tom_itx> it's crap to machine
[12:02:42] <anonimas1> 297 holes in a piece -_-
[12:06:28] <Tom_L> anonimas1
[12:06:57] <Tom_L> this says .008 chip load for mills
[12:07:58] <JT-Shop> eww copper
[12:08:22] <Tom_L> brinell A: 271 B: 64.3 C: 28 , tensile strength 129 1000's psi
[12:08:53] <JT-Shop> copper alloy or soft copper?
[12:09:03] <Tom_L> slab: .007, face: .010, endmill: .008 chip load
[12:09:44] <Tom_L> surface speed: HSS 120-170 carbide: 400-500
[12:09:46] <anonimas1> soft copper
[12:09:49] <Tom_L> power factor 1.5
[12:09:53] <syyl_ws> i would outsource the job ;)
[12:09:56] <JT-Shop> my book show similar FPT to aluminum but 1/2 the SFM
[12:10:01] <anonimas1> im the outsource...
[12:10:04] <anonimas1> :p
[12:10:06] <syyl_ws> oh
[12:10:06] <Tom_L> syyl_ws, anonimas1's not like that :)
[12:10:29] <Tom_L> sounds like fairly constant feed/speed
[12:10:44] <syyl_ws> how deep are the holes?
[12:10:48] <Tom_L> it's just real stringy to machine and a general PITA
[12:10:48] <anonimas1> 10mm
[12:10:58] <anonimas1> I think im feeding too slow.
[12:11:11] <Tom_L> those are the numbers from my drill chart
[12:11:26] <Tom_L> for copper / bronze
[12:11:44] <anonimas1> 5k rpm and 660mm/min
[12:11:48] <anonimas1> about there.
[12:12:07] <syyl_ws> hm doesnt sound to wrong
[12:12:16] <anonimas1> im feeding too slow, but the drills are breaking
[12:12:18] <syyl_ws> would go for a bit higher feed
[12:12:28] <anonimas1> im off by a factor of 10 too slow.
[12:12:29] <syyl_ws> flood lubrication?
[12:12:31] <Tom_L> try some tap lube too
[12:12:35] <anonimas1> yes.
[12:12:35] <Tom_L> that works wonders
[12:12:36] <anonimas1> -_-
[12:14:01] <syyl_ws> i have often copper parts to machine at work
[12:14:20] <syyl_ws> but never such small holes...
[12:14:29] <syyl_ws> but its still a pitty to machine ;)
[12:14:53] <anonimas1> we'll see soon. im going to go try it later..
[12:15:09] <Tom_L> laser?
[12:15:18] <syyl_ws> 10mm deep in copper?
[12:15:18] <syyl_ws> Oo
[12:15:22] <Tom_L> heh
[12:15:46] <anonimas1> hehe
[12:16:10] <syyl_ws> maybe shoot the holes with a canon trough.. ;)
[12:17:01] <anonimas1> hehe, it should work. period, it's been done before on shittier machines
[12:17:02] <anonimas1> :)
[12:17:14] <Tom_L> it's probably grabbing the cutter
[12:17:35] <anonimas1> at 75mm/min and 5k rpm?
[12:18:16] <anonimas1> and flood coolant..
[12:18:21] <anonimas1> bbl we'll see what happens.
[12:22:23] <anonimas1> thanks for the help!
[12:23:48] <Tom_L> anonimas1,
[12:23:58] <Tom_L> if all else fails try the tap lube
[12:24:08] <Tom_L> it may help some
[12:25:25] <syyl_ws> old day machinists used milk...
[12:25:32] <syyl_ws> some day i will try it
[12:25:41] <syyl_ws> but only if theres on one else in the shop...
[12:25:51] <Tom_L> :)
[12:25:53] <syyl_ws> "watch...now he is completely crazy..."
[12:25:56] <IchGuckLive> B)
[12:30:52] <Loetmichel> milk WILL work... but only if direct from the farmer, not the watered down stuff wirth 3,5% fat.
[12:31:15] <Loetmichel> AND you shoud be sure that NOTHING of it can pour into the coolant tank.
[12:31:24] <Loetmichel> BIG stink after a few days!
[12:31:58] <Tom_L> high butterfat content makes sense
[12:33:47] <DJ9DJ> hrhr
[12:44:53] <JT-Shop> I use dish washing liquid for ally, wonder if it works for copper too
[12:49:05] <IchGuckLive> copper is best to cut on EDM or a realy sharp tool
[12:49:57] <Tom_itx> anybody ever try tools that were cryo frozen?
[12:50:56] <IchGuckLive> in University to mill in to carbon
[12:54:10] <IchGuckLive> http://www.retsch.com/products/milling/mixer-mills/cryomill/
[13:00:37] <IchGuckLive> happy milling by and Gn8
[13:15:16] <elmo40> this April is another LTS release. I cant believe its been 2 years since 10.04
[13:15:34] <elmo40> Any plans on making a liveCD using it?
[13:26:38] <Mjolinor> solved the problem I had with the drill mask for export from PCB. It seems that if you do not have any copper on the bottom of the PCB then "export gcode" will only give you the top copper layer adn no drill mask
[13:26:55] <Mjolinor> not sure if that is a bug or not as there doesn't seem to be any documentation on it
[13:33:55] <pcw_home> elmo40: I think there are RTAI issues with the new 3.2 kernel in 12.04 lts
[13:43:26] <elmo40> that can be a problem.
[14:30:51] <anonimas1> heh, looks like I have a tool quality issue
[14:30:53] <anonimas1> -_-
[14:30:58] <anonimas1> didnt work with thoose feeds..
[14:31:14] <JT-Shop> as in gummed up and broke?
[14:31:23] <anonimas1> no as in explosively broke on contact
[14:31:32] <anonimas1> and the other one lasted 70 holes..
[14:31:40] <anonimas1> then explosion..
[14:32:31] <JT-Shop> ouch
[14:32:44] <anonimas1> i cant even narrow it down by feed/speed
[14:32:57] <anonimas1> since I tried less/more from the point where it should be
[14:33:20] <JT-Shop> it could be the material too
[14:33:37] <anonimas1> my previous with wrong feed/speed did the sam
[14:33:38] <anonimas1> e
[14:33:48] <anonimas1> 4mm deep and it / to the side and broke
[14:34:08] <Tom_itx> maybe it's workhardening
[14:34:43] <syyl__> ah right
[14:34:44] <anonimas1> in random spots?
[14:34:45] <syyl__> the tool
[14:34:57] <syyl__> try a ground drill
[14:35:00] <syyl__> not a rolled one
[14:35:01] <anonimas1> my cam program sorts them by shortest path, so they arent even in vincinity..
[14:35:20] <anonimas1> not all the time, ie, zig zag around..
[14:35:35] <anonimas1> it happened in random spots in the piece..
[14:35:49] <anonimas1> (force starting a new hole in random spot)
[14:36:22] <Tom_itx> does it wander from the get go?
[14:36:27] <anonimas1> no
[14:36:28] <Tom_itx> are you drilling a spot first?
[14:36:58] <anonimas1> no
[14:37:18] <anonimas1> the first holes i did i checked for wandering and it dosent do that at all
[14:37:30] <mrsun> hmm, why is the pwm inverted when i run the spindle CCW ? :/
[14:37:30] <Tom_itx> mmm
[14:37:55] <anonimas1> if they wandered they would kill the holes around since it's a matrix of holes
[14:38:01] <anonimas1> err it..
[14:38:12] <mrsun> got a pin 16 as spindle pwm, pin 1 as spindle cw (works fine) and pin 14 as spindle ccw (does not work as pressing + for speed or doing m4 s1000 lowers the voltage fromt he pwm to 0)
[14:40:52] <mrsun> oh loadrt pwmgen output_type=1 aparently fixes that
[14:41:28] <mrsun> noo
[14:41:41] <mrsun> output_type 1 aparently is pwm/dir
[14:43:23] <anonimas1> im suspicious about the material since i got that provided..
[14:43:48] <Tom_itx> got a hardness tester?
[14:44:18] <anonimas1> no
[14:54:02] <mrsun> setting output_type to 1 did not helpo
[14:55:44] <mrsun> hmm, does anti clockwise rotation input negative numbers ?
[15:04:54] <mrsun> shouldnt it be like M3 S1000 would set Parport pin CW high, and pwm from 0 - 100%, if M4 S1000 it should be Parport Pin CCW high and pwm from 0 - 100% ?
[15:05:00] <mrsun> why is the pwm inverted as it seems? :/
[15:05:05] <mrsun> or not working at all
[15:05:09] <mrsun> as i cant rev up the spindle at all in ccw
[15:05:16] <mrsun> it just idles at a very low speed
[15:07:04] <pcw_home> do you have a CW and CCW input on the VFD?
[15:09:47] <mrsun> ahh M4 aparently sets the speed to negative value
[15:09:56] <mrsun> so M4 S1000 would be equal to -1000
[15:10:06] <mrsun> pcw_home, yes, two inputs
[15:10:11] <mrsun> one for CW and one for CCW
[15:10:35] <mrsun> found a log where alex_joni said that the spindle stuff need to be connected to some abs singal thingie
[15:10:44] <mrsun> to make it positive even for M4
[15:10:45] <pcw_home> so do you take the PWM DIR and invert it to drive CCW
[15:10:51] <pcw_home> ?
[15:11:27] <mrsun> pcw_home, got two pins on the parport to make it CW or CCW
[15:11:33] <pcw_home> It looks like the PWMGEN comp should do that (it must use negative inputs in mode 1)
[15:11:33] <mrsun> as the vfd needs seperate inputs
[15:12:08] <mrsun> so got P1 to CW input on VFD, P14 to CCW on VFD and P16 as PWM for vfd (0 - 10.5V)
[15:12:20] <pcw_home> so you have your mode 1 PWMGEN wired so DIR goes to CW and inverted DIR goes to CCW?
[15:13:12] <mrsun> [20:35:18] <alex_joni> net spindle-cmd <= motion.spindle-speed-out => abs.0.in
[15:13:13] <mrsun> [20:35:32] <alex_joni> net spindle-abs-cmd <= abs.0.out => pwmgen.0.value
[15:14:41] <mrsun> pcw_home, no mode 0 atm
[15:14:41] <mrsun> tried the mode 1 thingie as someone had written on the forums that that worked
[15:14:41] <pcw_home> Mode 1 of the PWMGEN makes no sense if it does not do the ABS inside
[15:14:41] <pcw_home> (the manual could be clearer on this)
[15:16:27] <mrsun> will try that abs trick tomorrow
[15:16:32] <mrsun> atm i feel like im going to die ... :P
[15:16:45] <JT-Shop> pcw_home: which manual?
[15:16:57] <pcw_home> pwmgen
[15:17:34] <pcw_home> I can see that ABS is needed in mode 0 but should be done internally in mode 1
[15:17:56] <pcw_home> (otherwise mode 1 is useless)
[15:18:20] <JT-Shop> just reading it now
[15:18:42] <JT-Shop> so mode 1 only adds the direction output?
[15:20:08] <JT-Shop> I see hint I think "The duty cycle on the PWM pin is based on the absolute value of the command, so negative values are acceptable."
[15:20:42] <pcw_home> If mode 1 actually works for negative inputs it need to output DIR based on the input sign
[15:20:44] <pcw_home> _and_ PWM proportional to the _absolute value_ of the input
[15:23:14] <pcw_home> maybe I'm looking at an older version
[15:23:41] <JT-Shop> unfortunately I can only try and explain how it works in the manual, however I would agree with your explanation of how it should work.
[15:23:50] <JT-Shop> I'm looking at the 2.5 docs
[15:23:52] <pcw_home> and that hint only applies to mode 1
[15:24:08] <JT-Shop> http://linuxcnc.org/docview/2.5/html/hal/rtcomps.html#_pwmgen_a_id_sec_pwmgen_a
[15:24:10] <JT-Shop> yes
[15:24:57] <pcw_home> OK thats better (is that the same as the man page?)
[15:25:47] <mrsun> so type 1 should work ?
[15:25:51] <mrsun> but where do i throw the dir pin ?
[15:25:54] <mrsun> i dont want it =)
[15:26:24] <pcw_home> Yes but you need to drive CW from DIR and CCW from inverted DIR
[15:26:44] <mrsun> umm and how would i do that then :/
[15:26:58] <pcw_home> (better still would be to gate these with an internal enable)
[15:27:31] <mrsun> pcw_home, but will it ever be able to stop then ?
[15:27:42] <mrsun> as no signal on CW and no signal on CCW equals stop for the VFD
[15:28:00] <pcw_home> Thats why you want the gate I mentioned
[15:28:04] <mrsun> using cw and inverted for ccw it would never have two open contacts
[15:28:23] <mrsun> pcw_home, but wouldnt the abs trick work as well ?
[15:28:27] <mrsun> and alot easier to implement? :)
[15:29:21] <JT-Shop> no the man page is different :/
[15:29:30] <pcw_home> maybe, do you already have signals to drive CW and CCW ?
[15:30:17] <mrsun> pcw_home, yes its all connected up
[15:30:39] <mrsun> and working both clockwise and counter clockwise tho ccw i cant rev the spindle any higher then like 5hz
[15:30:51] <mrsun> due to the negative output for the pwm
[15:30:58] <mrsun> (so doing + makes the pwm signal 0)
[15:30:59] <pcw_home> OK yeah then the mode0/abs should work (or mode 1 and dont connect dir)
[15:31:28] <mrsun> tried the output_type=1 but it behaved the same way
[15:32:29] <pcw_home> Are you saying that if you feed a negative number to pwmgen in mode 1 that it output is 0? if so thats a bug
[15:33:11] <mrsun> pcw_home, seems like it
[15:33:18] <mrsun> as it behaves the exact same way as type=0
[15:33:54] <pcw_home> can you check the actual PWM output after a setp fullscale+ and fullscale -?
[15:34:27] <mrsun> pcw_home, not atm but i can try and check tomorrow, you mean with halscope or ?
[15:37:10] <pcw_home> Just measuring the output voltage ought to be close enough
[15:38:27] <mrsun> ok =)
[16:10:07] <DJ9DJ> gn8
[16:21:40] <Loetmichel> *uuuups* ...
[16:21:58] * Loetmichel collects the workpiece from across the room...
[16:23:08] <Loetmichel> planing aluminium with a 6mm 2flute TC bit @ 16000 rpm and 800mm/min 1mm deep was a BIT much... Cyancacrylate glue melted-> workpiece gon flying ;-)
[17:02:55] <elmo40> anonimas1: i just came in here, what are you drilling, what size, what speeds/feeds are you trying?
[17:04:39] <anonimas1> copper, 5k rpm and 600mm/min
[17:04:48] <anonimas1> 2mm drill
[17:06:28] <elmo40> 5,000 rpm? wow. that is high, even for 2mm drill
[17:08:01] <anonimas1> mhm, got a better idea for the speed?
[17:19:11] <elmo40> carbide tool?
[17:19:48] <elmo40> drilling? what is your point angle?
[17:20:40] <elmo40> http://www.busbymetals.com/docs/mach_page09.htm
[17:22:00] <elmo40> http://www.cuttingtoolexpress.com/html/speeds_and_feeds_-_drilling.html
[17:22:14] <elmo40> slow speeds for copper.
[19:47:45] <skunkworks__> ?
[19:48:03] <skunkworks__> huh. from my perspective I thought I wasn't connected
[20:06:33] <cstop> non
[20:07:14] <danimal_laptop> hi
[20:10:01] <Jymmm> ping
[20:12:49] <Jymmm> Hi seb_kuzminsky!
[20:13:55] <seb_kuzminsky> hi there :-)
[20:19:55] <joe9> need some advice, please? I am thinking about this: "Light-Pressure Drill-Feed Attachment" #3100A45
http://www.mcmaster.com/#catalog/118/2422 and using it with either of these 2 drill bits (
http://www.mcmaster.com/#2841A81 or
http://www.mcmaster.com/#2860A94).
[20:20:09] <joe9> Any suggestions on which would be a better drill bit choice?
[20:20:36] <joe9> or, what do you think of this adapter?
http://www.mcmaster.com/#30505A5
[20:20:52] <joe9> I am trying to drill through holes with that drill bit.
[20:49:37] <Connor> Which book is the "bible" of Machining?? and can it be gotten in ebook/pdf form ?
[20:50:54] <cstop> machineries Hand Book is a useful standard. No idea about ebook etc/
[20:55:10] <Tom_L> Connor i think you can get it on cd
[20:55:22] <Tom_L> but i like the machinist handbook
[20:55:32] <Tom_L> number (insert current number)
[20:55:48] <Tom_L> Machinery's Handbook
[20:56:11] <Tom_L> 28 maybe?
[20:56:16] <Tom_L> 29 who knows by now
[20:57:09] <archivist> I have number 13
[20:57:21] <Tom_L> i have 25
[20:57:28] <Tom_L> you are dated
[20:59:45] <archivist> I was wrong too, number 8 and 14
[21:00:13] <Tom_L> all the basics are there
[21:00:17] <Tom_L> they just add new stuff
[21:09:32] <joe9> My drill press belt has "Haimen V belt M24". I googled it and it seems to be a V belt with effective length of 24 inches. What does the "M" of the "M24" mean?
[21:10:31] <joe9> got it, sorry for the bother. "Vee belts are measured by section and length ."
[21:14:37] <joe9> but, McMasterCarr does not have a "M" section.
[22:20:24] <danimal_laptop> any plasma experts in here?
[22:20:49] <danimal_laptop> trying to get my plasma cutter working, but it wont arc.
[22:21:05] <danimal_laptop> it has voltage between the nozzle and ground
[22:21:10] <danimal_laptop> and has air
[22:21:18] <danimal_laptop> torch is new
[22:22:28] <danimal_laptop> the plasma cutter is 30A but the tip is rated for 90-100a, will it not work with a nozzle rated that high?
