[00:59:39] <CaptHindsight> anyone recall the brand of mini lathe that Skunkworks was playing with a couple of months ago
[01:00:16] <CaptHindsight> I thought it was larger than a Sherline but maybe I'm wrong
[01:00:20] <jdh> emco

[01:01:04] <CaptHindsight> http://www.cnccookbook.com/img/OthersProjects/EmcoLathe.jpg like this
[01:01:50] <andypugh> I think they were the Compact5 PC, without the built-in controller
[01:02:06] <CaptHindsight> good size to use for a cnc lens polisher/grinder
[01:02:08] <Tom_itx> wasn't that unimat?
[01:03:13] -!- mhaberler has quit [Quit: mhaberler]
[01:03:23] <andypugh> Emco == Unimat
[01:03:29] <skunkworks> emco
[01:03:47] <skunkworks> right - compact 5 pc
[01:04:15] <Tom_itx> finally, maybe i have a chance now to work on this config
[01:04:18] <jdh> did you sell them all?
[01:04:44] <skunkworks> http://electronicsam.com/images/emco/emcoclose.JPG
[01:04:54] <CaptHindsight> skunkworks: whats the accuracy like on those in good shape?
[01:05:05] <skunkworks> he has sold maybe 6 of them so far.. Sold 3 saturday to a guy from kansas
[01:05:22] <Tom_itx> whereabouts in ks?
[01:05:32] <Tom_itx> maybe i'll go swipe one
[01:05:35] -!- R2E4__ has quit [Remote host closed the connection]
[01:05:48] <skunkworks> They are well built - I don't know the spec. the steppers installed will do about .00025 halfstepping

[01:06:29] <Loetmichel> yeas, MUCH better wuality than cHinese
[01:07:01] <andypugh> The bed is still rather narrow for the centre height

[01:10:49] <andypugh> The bar-bed unimats are a bit of a toy
[01:11:41] <CaptHindsight> it would only see polycarbonite and glass
[01:11:53] <R2E4> pncconf: where do you select the mpg? 1st or second?
[01:12:15] <andypugh> http://www.ebay.com/itm/151195523318 is a bit more serious
[01:12:58] <CaptHindsight> a bit much for 90mm plastic
[01:13:43] <andypugh> Maybe sperm whales need contacts?
[01:15:12] <R2E4> found it

[01:29:52] <CaptHindsight> looks like they don't make the small lathes anymore
[01:29:54] <skunkworks> not yet - I was hoping to try it on the emco lathes but have not. (well - I have run it RIP - not simulator...) I don't know which you mean
[01:30:19] <CaptHindsight> http://www.emco-world.us/en/products/industry/turning.html
[01:31:48] <CaptHindsight> looks like I'll have to search in China
[01:32:08] <CaptHindsight> spec grade
[01:32:09] <skunkworks> CaptHindsight: I don't remember - 2500 iirc
[01:32:10] -!- tinkerer has quit [Quit: Leaving.]
[01:33:34] <skunkworks> no - something over 2800rpm
[01:33:57] <CaptHindsight> I'd need a bunch of new ones
[01:34:17] <CaptHindsight> I thought they were still in production
[01:34:43] <skunkworks> I think they make close to the same thing but it is a slant bed
[01:35:33] <atom1> skunkworks, i set this up with my configs and it runs the axis ok
[01:35:42] <atom1> mdi tool change doesn't seem to work
[01:35:52] <CaptHindsight> http://www.alibaba.com/product-gs/1174285494/linear_motor_dc_12v.html must be one of those rotary linear motors :)

[01:38:22] <andypugh> it's just possible that the shaft moves in and out not round and round

[01:38:46] <jdh> and it's explosion proof
[01:40:31] <CaptHindsight> Commutation: Brush and explosion proof
[01:40:37] <andypugh> "Explosion Proof" means it won't ignite gas.
[01:40:57] <CaptHindsight> sealed or bullshit?
[01:41:00] <andypugh> Not normally associated with brush commutation though.
[01:41:03] <jdh> I'd go with BS
[01:44:53] <atom1> skunkworks, what's the difference between SIM and RIP?
[01:46:28] <atom1> i noticed that spiral test has no tool associated with it
[01:46:38] <andypugh> SIM doesn't compile any hardware drivers, RIP is a self-contained installation in a directory, rather than one installed in /usr/bin
[01:47:01] <atom1> ok
[01:47:02] <andypugh> You can actually compile something that is SIM _and_ RIP
[01:47:03] -!- sumpfralle has quit [Ping timeout: 260 seconds]
[01:47:14] <atom1> but it will run gcode?
[01:47:21] <andypugh> yes
[01:47:45] <atom1> i was testing this out a bit but MDI toolchange doesn't wanna work
[01:48:08] <andypugh> I don't even know what you mean by "MDI toolchange"
[01:48:33] <atom1> typing a T1 M6 G43 in the MDI dialog
[01:48:57] <andypugh> which config?
[01:49:09] <atom1> my sherline config from 2.5.3
[01:49:31] <CaptHindsight> http://gmbearing.en.alibaba.com/productgrouplist-214696341/CNC_Machine_Units.html
[01:49:37] <andypugh> Does that use hal_manualtoolchange?
[01:50:50] <andypugh> CaptHindsight: They sell "Corss Roller Linear Guides With Good Qulaity and Price"
[01:51:12] <atom1> yes
[01:51:26] <andypugh> Is the dialog box hiding?
[01:51:55] <CaptHindsight> they nead a beeter spel cheker
[01:52:13] <atom1> but i also copied my modified ver of it so lcnc would run with my config
[01:52:22] <atom1> the dialog box isn't hiding
[01:52:38] <atom1> it allows entry but doesn't execute it
[01:52:52] <andypugh> Is the tool_changed pin being asserted?
[01:53:13] <atom1> it does depress the pause button in axis
[01:53:23] <atom1> lemme check
[01:54:25] <atom1> no
[01:54:51] <atom1> no activity on any of the toolchange vars

[01:55:09] <andypugh> Sounds like a net problem, or your toolchange code is borked
[01:55:12] <atom1> hal_manualtoolchange.number is 1
[01:55:33] <atom1> it's the mod that was supposedly pushed to master
[01:55:50] <atom1> to add the physical button

[01:56:26] <andypugh> are the tool change request and complet pins netted?
[01:56:47] <atom1> yeah

[01:57:05] <atom1> net tool-changed iocontrol.0.tool-changed <= hal_manualtoolchange.changed

[02:01:43] <CaptHindsight> hey tjtr33
[02:01:52] <tjtr33> damn its cold!
[02:02:01] <CaptHindsight> heh
[02:03:04] <atom1> andypugh, the idea was to be able to do hardware tests on the new TP code
[02:03:16] <atom1> so tool changes would play into that
[02:03:34] <CaptHindsight> looks like it won't be quite as cold as expected, only -20F
[02:03:46] <andypugh> So, M61 will load a tool, without actually triggering a tool change.
[02:03:47] <atom1> i'll try it with the original toolchange script and see if it matters
[02:04:20] <andypugh> Night all
[02:04:23] <atom1> just a matter of commenting out my button line
[02:04:25] <atom1> later
[02:04:25] <tjtr33> CaptHindsight, have servos been used with BBones? ( i only find the toy rc airplane 'servos' mentioned )

[02:04:28] <tjtr33> night andy
[02:05:01] <CaptHindsight> tjtr33: did you ever come across a taiwan supplier of linear positioners with lesser than Hiwin quality?
[02:05:32] <tjtr33> no, i bought a used SMAC voice coil and amp tho
[02:05:47] <CaptHindsight> better than drawer slides but not aerotech
[02:06:04] <CaptHindsight> how did that coil turn out?
[02:06:14] <CaptHindsight> enough torque?
[02:06:47] <tjtr33> try Star? their salesmen thoguht they were gresat ( fwiw :)
[02:07:21] <tjtr33> the units on the bench, got a 48V p/s from Mr Kee Ling ( aka automation mumble )
[02:07:50] <tjtr33> haha im a terrible typist w/o frostbit fingers :)
[02:08:07] <CaptHindsight> maybe something like bolt on makerslide that has been precision ground
[02:09:44] -!- patrickarlt has quit [Remote host closed the connection]
[02:10:00] <tjtr33> the postion of the electrode is pretty tight, the process is changes a lot with with 10um position change,
[02:10:19] <tjtr33> so 'sloppy' to me is not everyone else's measure
[02:10:55] <CaptHindsight> I'd like the precision but without the durability

[02:16:04] <CaptHindsight> makerslide was a joke, he acts like he invented extrusions
[02:18:40] <tjtr33> has anyone used servos ( ac/dc with encoder feedback ) on a BeagleBone? seems devs are step-centric
[02:19:29] <CaptHindsight> not with the Bone, I'm going to try servos with the cubieboard soon

[02:21:43] <CaptHindsight> andy got his imx6 + arduino board, so there could be more ARM boards to play with soonish

[02:23:49] <atom1> ok, running a gcode file the toolchange works however using the MDI window it doesn't
[02:23:55] <tjtr33> so udoo _is_ imx6, by freescale. cool
[02:24:16] <CaptHindsight> yeah with an Atmel SAM on the same board
[02:24:27] <CaptHindsight> http://www.udoo.org/
[02:25:26] <CaptHindsight> we are going to try and get the FPGA anything IO card working with the cubie
[02:26:14] <atom1> sounds like fun
[02:26:18] <tjtr33> urgh urf oog you segwayed into Mesa land with another holy grail best of luck, maybe i can help somehow
[02:26:54] <CaptHindsight> http://hardkernel.com/main/products/prdt_info.php another ARM board that might be worth supporting since it has a decent GPU
[02:26:55] <tjtr33> atom1 sorry dont knwo why your MDI didnt work while gcode file did
[02:27:12] <atom1> this is 2.6 i'm testing

[02:32:08] <CaptHindsight> atom1: which board?
[02:32:19] <atom1> the udoo

[02:34:09] <atom1> single dual or quad?
[02:34:23] <tjtr33> ChuangTzu a Tree? so bridgeport sized? maybe ask Igor Chudev ( linuxcnc user in Chi area , also used machinery dealer )
[02:34:32] <skunkworks> CaptHindsight: I think this is the current 'compact 5'

[02:34:57] <atom1> skunkworks, there's something odd about tool changes with this code
[02:35:07] <CaptHindsight> http://www.ebay.com/itm/261299862995
[02:35:35] <skunkworks> atom1: there could be... what does it do?
[02:36:09] <skunkworks> (this is pretty new code - he has re-writen it in just a few months)
[02:36:10] <atom1> running gcode it does a regular toolchange and the dialog box comes up but in the MDI window nothing happens
[02:36:37] <atom1> check halconfig and no activity there either
[02:36:52] <skunkworks> might want to explain it on the devel list - circular blend thread
[02:37:26] <atom1> i don't think i've ever been on the list :)
[02:37:39] <skunkworks> does it work in 'normal' master?
[02:37:50] <atom1> haven't tried that
[02:37:59] <atom1> how would i recompile for that?
[02:38:43] <skunkworks> I would just pull master into a new directory and build.
[02:38:49] <atom1> ok
[02:39:07] <skunkworks> then you can switch between the two - that is what I do to compare the performace between the two

[02:47:36] <skunkworks> so - I was standing in front of my laptop the other day - I was resting my elbow on the corner of it... It made a squealing noise.. Took me a second to figure out it was my laptop. I though - I don't remember the fan being there... oh well.
[02:48:00] <skunkworks> today I did it again - and it dawned on me when my laptop locked up - that the hd was under my elbow...

[02:49:35] <tjtr33> i'm cranking the car over now to make sure
[02:49:38] <CaptHindsight> takes me maybe 3 hours to restore my Linux systems, 3-5 days for win7
[02:49:52] <jdh> 64F here
[02:50:05] <CaptHindsight> <-- parks indoors
[02:50:11] <skunkworks> -6F at the moment..
[02:50:18] <CaptHindsight> 58F in the shop
[02:50:29] <jdh> geez... people live like that?

[02:51:35] <CaptHindsight> 53F in Nanjing but I'm stuck here
[02:51:48] <tjtr33> i got email from buddy in Kph Phanagn today, he's coming back to skokie, i told him dont! kick a cop or something, anything but dont come now.
[02:51:55] <tjtr33> Koh
[02:52:03] <somenewguy_chips> CaptHindsight: souns about right
[02:52:36] <somenewguy_chips> I remember in like 05 or so when linux officially became the eaieer install than windows for a non-technical person...
[02:52:41] <somenewguy_chips> and the gap has only gorwn
[02:52:44] <somenewguy_chips> grown
[02:53:18] <somenewguy_chips> skunkworks: I think its about time for you to buy a lottery ticket
[02:53:29] <ChuangTzu> i bike to work
[02:53:39] <ChuangTzu> going in tomorrow. fuck what they say
[02:53:40] <CaptHindsight> how far?
[02:53:44] <ChuangTzu> 7 mi each way
[02:53:46] <somenewguy_chips> bike commute for ever!
[02:53:47] <tjtr33> i thought you were in Chi
[02:53:49] <ChuangTzu> i am
[02:54:01] <CaptHindsight> ^^ south sider
[02:54:05] <ChuangTzu> yup
[02:54:17] <tjtr33> wear a mask so you dont freeze your lungs
[02:54:31] <ChuangTzu> it's not even going to be that cold. i don't know why everyone is freaking out
[02:54:39] <somenewguy_chips> how cold?
[02:54:42] <ChuangTzu> -10f
[02:54:47] <somenewguy_chips> hahah
[02:54:53] <CaptHindsight> I'm just tired of cold and snow already is all
[02:55:03] <CaptHindsight> yeah -20F, been there
[02:55:04] <tjtr33> not as cold as predicted but not healthy fer sure
[02:55:13] <somenewguy_chips> I'm tired of the damn snow getting into the shop...
[02:55:18] <ChuangTzu> yeah, it's a pain
[02:55:19] <somenewguy_chips> freaking water damage
[02:55:30] <somenewguy_chips> previous owners were hippies and useless I guess
[02:55:39] <ChuangTzu> but at least when it's -10, even the salt water freezes so i don't have to deal with all the muck on my bike
[02:55:47] <ChuangTzu> the muck is the worst
[02:55:50] <somenewguy_chips> or squirrels, I have not ruled out squirrels at this point
[02:55:54] <somenewguy_chips> salt muck
[02:55:56] <CaptHindsight> back in the 80's this would be about the time my trans or clutch would need to replaced in the snow
[02:56:01] <ChuangTzu> heh
[02:56:07] <somenewguy_chips> I thought my bike was covered in snow and ice
[02:56:10] <tjtr33> haha busting ice-cicles off gutter, filling them with salt & laying out heater cables today
[02:56:21] <somenewguy_chips> then when my hands went all dreid out slug on me, I realized what I was cleaning up...
[02:56:49] <ChuangTzu> i wish they'd stop salting
[02:56:53] <ChuangTzu> and use sand/gravel instead
[02:57:07] <CaptHindsight> won't happen here
[02:57:13] <tjtr33> yeh, better idea, just hard to clean up
[02:57:21] <ChuangTzu> they have trucks that suck it up
[02:57:24] <ChuangTzu> basically street cleaners
[02:57:30] <ChuangTzu> so you can reuse like 90% of it
[02:57:35] <CaptHindsight> I think they use sand up in Milwaukee
[02:57:42] <tjtr33> elgin street sweepersw ( yay elgin illinois :)
[02:57:58] * ChuangTzu spent 3 winters in finland
[02:58:22] <CaptHindsight> so you're no stranger to cold
[02:58:38] <tjtr33> stranger to the sun tho
[02:58:48] <ChuangTzu> depends on the time of year
[02:58:59] <ChuangTzu> land of the midnight sun in the summer
[02:59:18] <ChuangTzu> i forgot to mention that i was there for 3 summers too
[02:59:26] <CaptHindsight> mosquito free?
[02:59:27] <ChuangTzu> i think andypugh goes there every winter too
[02:59:33] <ChuangTzu> up in lapland
[02:59:50] <ChuangTzu> yeah, mosquitos stopped biting me sometime when i lived in florida
[02:59:52] <CaptHindsight> he said Minnesota or canada this year

[03:13:21] <atom1> skunkworks, master does the same thing
[03:13:40] <CaptHindsight> do people buy oscilloscopes and not know how to fix them? I was surprised by how many questions are on the forums about scope issues
[03:16:02] <ChuangTzu> hmm, i wish i had a scopt
[03:16:11] <atom1> however master did have the modified hal_manualtoolchange in it
[03:16:33] <skunkworks> atom1: ah
[03:16:50] <atom1> i wonder if his ver overwrote that
[03:17:29] <skunkworks> I would guess it is a change in master that doesn't work the same as 2.5 or whatever you run normally
[03:18:19] <atom1> odd it works ok running gcode
[03:19:02] <skunkworks> you will have to explain the issue to someone in the know..
[03:19:17] <atom1> where would i do that?
[03:19:58] <skunkworks> either the mailing list, post a bug on source forge or get on linuxcnc-devel and ask.. (although 1 or 2 is proably the best)
[03:20:01] <atom1> -devel?

[12:25:09] <skunkworks> pretty consistant - -20 to -21 the whole drive in
[12:25:29] <R2E4> you guys familiar with 7i77?
[12:25:36] <skunkworks> quite windy though - that is the worse
[12:25:55] <skunkworks> is that the servo interface or stepper?
[12:26:03] <R2E4> I am trying to connect mpg to it.
[12:26:04] <Tom_itx> R2E4 don't interrupt the morning weather report!
[12:26:21] <R2E4> servo interface. I am trying to get a mpg connected and tested today
[12:26:37] <R2E4> ITs fucking cold and icy. What else is there to say
[12:26:45] <Tom_itx> R2E4 run dmesg or halcmd show pin to find the encoder pins
[12:27:14] <skunkworks> R2E4, did you read back?
[12:27:16] <skunkworks> [03:50:43] <pcw_home> R2E4: you need to set the sserial mode to 3 to have the MPG option available
[12:27:16] <skunkworks> [03:50:45] <pcw_home> (though I dont know if this is supported in pncconf) If not supported you will have to add the
[12:27:16] <skunkworks> [03:50:46] <pcw_home> MPG plumbing in the HAL file yourself
[12:27:34] <Tom_itx> oh yeah, and that ^^
[12:27:37] <R2E4> Its not connected yet, thats the point. Pncconf
[12:27:41] <R2E4> ah, shit
[12:27:53] <skunkworks> don't be afraid...
[12:28:05] <Tom_itx> make sure your field voltage isn't more than the mpg will be happy with
[12:28:55] <R2E4> the docs says you can use it on pins 16, 17,18 and 19, but there is no option in pncconf there, just the encoder slots you can select hand wheel
[12:28:57] <jthornton> I have a 7i77, let me look that up for you in the manual
[12:28:58] <Tom_itx> read up on it grasshopper
[12:29:24] <R2E4> I have been reading for weeks, and I don't think its going to work out!!!
[12:29:32] <jthornton> pncconf can not do it all, sometimes you have to venture out on your own
[12:29:46] <Tom_itx> just when you start to think that, it will all fall together
[12:30:08] <Tom_itx> yeah jump off the deep end and open up the config files yourself
[12:30:19] <R2E4> I wanted to get a head start on it, thought hooking up an mpg was a start, but apparantly not. I dont want to start with the servo amps....
[12:30:32] <Tom_itx> good idea
[12:30:36] <Tom_itx> start with estop
[12:30:43] <Tom_itx> then maybe the mpg
[12:30:51] <Tom_itx> then work to the limit switches
[12:30:54] <Tom_itx> then maybe the amps
[12:30:59] <jthornton> start with a blank config and go from there
[12:31:42] <Tom_itx> may the force be with you
[12:31:46] <R2E4> I started with pncconf with adding the pwm for axis and encoders. I can start linuxcnc with it. Can I start from there?
[12:32:32] <jthornton> you can drop pncconf any time you like if that is what you mean
[12:32:33] <Tom_itx> long as it matches the boards you have
[12:32:37] <R2E4> Listen, maybe your not hearing me...... I am not Frodo's brother, I dont have the ring, so starting with a blank config is just asking for Orc visitors.
[12:33:06] <R2E4> haha
[12:33:22] <Tom_itx> last drop in the cup is gone... i'm out
[12:33:23] <jthornton> but you will know what you have after
[12:34:21] <R2E4> So I have used pncconf for motors and encoders so I will start looking at that and then try for the e-stop, then mpg with manually configging the hal.
[12:35:52] <R2E4> Let me look at your docs on the 5i25 and 7i77 configs and see if mine are similar
[12:36:19] <jthornton> what mode did pnconf leave you in for the 7i77
[12:36:21] <jthornton> ?
[12:36:35] <R2E4> let me check
[12:38:09] <jthornton> what does the loadrt hm2_pci config= line have on it in your .hal file?
[12:42:13] <R2E4> loadrt hm2_pci config=" num_encoders=6 num_pwmgens=0 num_3pwmgens=0 num_stepgens=0 sserial_port_0=000xxxxx "
[12:43:03] <jthornton> ok, that is mode 0 change it to sserial_port_0=300xxx" for mode 3 which enables the mpg inputs

[17:08:56] <JT-Shop> it's better to use 2 inputs, you have a ton of them
[17:09:01] -!- GuShH_ [GuShH_!GuShH_Lap@unaffiliated/gushh] has joined #linuxcnc
[17:11:04] <pcw_home> The reason to use the MPG inputs is that they
[17:11:06] <pcw_home> support 1X quadrature mode, the normal encoder inputs do not
[17:11:43] <pcw_home> so if you have a standard 100 PPT MPG, the MPG inputs are better
[17:12:04] <R2E4> ok, pins 16 and 17 it is then.
[17:12:42] -!- mhaberler has quit [Quit: mhaberler]
[17:13:34] <pcw_home> remember that the 5V MPG power needs to have a common gnd with the field power
[17:14:02] * JT-Shop takes notes
[17:14:12] <R2E4> It will be powered with the field power 12vdc.
[17:14:29] <pcw_home> OK
[17:15:05] <R2E4> I have a 5-12v mpg, http://irmtl.com/LinuxCNC/VM40/MPG/mpg.jpg http://irmtl.com/LinuxCNC/VM40/MPG/mpg1.JPG
[17:17:05] <pcw_home> as long as the outputs swing near ground that should be fine at 12V
[17:17:27] <pcw_home> (the threshold is set to 2.5V for MPG inputs)
[17:18:01] <R2E4> Then I'll power it with 5v to be sure no problems.
[17:18:59] <R2E4> nad tie the gnds together....:-)
[17:20:23] <pcw_home> Either way should be OK

[19:06:09] <Tom_itx> yeah the low pass works great for mpg

[19:09:57] <Tom_itx> R2E4 are you writing a book as you go?
[19:09:59] <pcw_home> I would always start by launching linuxcnc

[19:10:02] <pcw_home> halcmd show all > halobjects
[19:10:39] <pcw_home> and use halobject as a list of available pins,parameters etc
[19:11:35] <pcw_home> the encoder on the 7I77 field I/O has _no_ pins other than the count
[19:12:29] <pcw_home> so the mpg setup is simplified relative to the example

[20:34:59] <einar_> Single wheel knurling require a sturdy lathe.
[20:35:19] <WalterN> so you dont have to press as hard?
[20:35:39] <WalterN> with a two wheel one
[20:36:16] <einar_> You do! That's why a small lathe will have a problem. With 2 wheels the forces are between them and not on the x-slide.
[20:36:41] <WalterN> oh, you are talking about the kind that are not the bump kind
[20:36:52] <WalterN> the bump kind can be two wheel
[20:37:44] <einar_> This type is fine for small lathes: http://pastebin.com/RrSkb2T4

[20:39:52] <WalterN> yeah
[20:40:00] <WalterN> I've used that kind before
[20:40:09] <WalterN> and the bump style two wheel ones
[20:40:10] <einar_> This is a typical DIY tool.
[20:40:21] <WalterN> but never a single wheel one
[20:41:03] <einar_> I use a single wheel on my big lathe, and really have to force it.
[20:42:02] <WalterN> this lathe is rated at... 30hp I think?

[21:14:40] <einar_> Strangely enough it uses a PID even though it's a stepper system w.o. encoders.
[21:15:15] <PCW> the step generator is a velocity mode servo
[21:15:46] <einar_> I believe what the board does is just to copy the step counter as the encoder input.
[21:16:01] <PCW> the PID corrects for direction change time, timebase errors, etc
[21:17:14] <PCW> one thing I have noticed is that you want FF2 = period (so 0.001 at 1 KHz)

[21:25:04] <R2E4> What output you talking about?>
[21:25:34] <R2E4> I really didnt want to ask, but i have been trying to figure that one out, the enco increments allways the same.

[21:43:26] <einar_> I don't understand: Halscope shows it takes >500ms to get from 0 to 2000PPS (max)
[21:44:48] -!- PCW has quit [Remote host closed the connection]
[21:44:51] <einar_> My Tektronics says it takes 200ms. Which is about the same as the controller I'm throwing out, so should be OK for the motors & mechanics.

[21:47:58] <tjtr33> einar_, halscope works in multiples of the thread period. so its more accurate if the measurements are using 2x thread period ( sampling limitation )
[21:48:17] <PCW> einar_ no, servo thread period
[21:48:32] <PCW> (so 0.001 at 1 KHz)
[21:48:55] <tjtr33> i used to go nuts trying to measure 10uS pulses with hal. 1) i couldnt generate them with my thread 2) icouldnt measure them to 1 unit of thread period accuractely
[21:51:34] <einar_> Hmm. I think I'll dig up a frequency to voltage converter and hook up between Step out and Tek. It's quite fiddly to zoom/pan to find the shortest pulses where to place a cursor.

[22:25:41] <andypugh> ROFL. (Well, smued giggling anyway) I decided I wasn't actually comfortable with sudo not asking me for a password when I used sudo, so (looking on the internet blindly) I dud sudo visudo, and commented out the %sudo ALL... line.
[22:26:24] <andypugh> And now there are no accounts in the sudoers file to change it back :-)
[22:27:04] <andypugh> (smued = amused) Not sure how I got that that wrong.

[23:31:03] <WalterN> what does TPI mean when buying a knurling tool?
[23:31:06] <JT-Shop> very productive day here, got lots of the garage cleaned up and starting fabricating my hydraulic tank for my splitter. http://gnipsel.com/images/splitter/
[23:31:23] <WalterN> I want to match an existing knurl
[23:32:17] <andypugh> I would guess, turns per inch
[23:32:49] <andypugh> Bit if it is axiallly or circumfrentially I have no idea
[23:33:26] <WalterN> I have no idea
[23:33:36] <Tom_itx> or 'thread' per inch
[23:33:50] <WalterN> teeth per inch?
[23:33:58] <Tom_itx> basically the same thing
[23:34:17] <WalterN> http://www.innovativetoolsales.com/Dorian%20Circular%20Knurling%20Info.pdf
[23:35:03] <WalterN> ok, so I need a 14 tool
[23:37:51] <WalterN> its measured radially... (assuming round part)
