[00:13:45] <andypugh> dmesg?
[00:14:16] <atom1> it loads sim ok
[00:14:21] <r00t4rd3d> i say dmesh like a mexican
[00:14:26] <r00t4rd3d> dmesg*
[00:14:51] <r00t4rd3d> speedy gonzalis
[00:14:59] <atom1> i copied the config files over from 10.04 that i've been using
[00:15:05] <atom1> hang on i'll get dmesg
[00:15:13] <r00t4rd3d> tail -f it
[00:15:16] <r00t4rd3d> in a term
[00:15:28] <r00t4rd3d> tail -f /var/log/dmesg
[00:15:40] <r00t4rd3d> run your app and wait for errors
[00:16:11] <r00t4rd3d> real time! none of that sifting through a huge log
[00:16:50] <r00t4rd3d> like looking for a piece of corn in a pile of shit
[00:17:54] <andypugh> I would normally buy a new piece.
[00:18:39] <r00t4rd3d> recycle man!
[00:20:00] <Tom_L> andypugh, http://tom-itx.dyndns.org:81/~webpage/cnc/dmesg_text.txt
[00:20:13] <r00t4rd3d> corn hunt!
[00:20:16] <Tom_L> maybe a parport setting?
[00:20:26] <Tom_L> in the bios?
[00:20:26] <andypugh> [ 3424.967306] hm2_7i43: failed to clear EPP Timeout!
[00:20:26] <andypugh> [ 3424.969299] hm2_7i43: /DONE is not low after CPLD reset!

[00:20:36] <andypugh> I think the cable is unplugged
[00:20:40] <r00t4rd3d> lol
[00:20:43] <Tom_L> but it isn't
[00:20:47] <Tom_L> lemme double check
[00:20:48] <r00t4rd3d> is parport enabled?
[00:21:13] <Tom_L> lemme check the bios
[00:21:29] -!- atom1 has quit [Quit: Leaving]
[00:22:20] <andypugh> Also note that it is not finding the Bitfile, which is a separate and equallt serious problem.

[00:23:48] <Tom_L> it should, i copied it to /lib/firmware/hm2/7i43
[00:24:04] <r00t4rd3d> as user or root?
[00:24:08] <Tom_L> sudo
[00:25:03] <andypugh> capitalisation?
[00:25:08] -!- atom1 [atom1!~tom@unaffiliated/toml/x-013812] has joined #linuxcnc
[00:25:31] <r00t4rd3d> i would double check the file permissions also
[00:25:54] <r00t4rd3d> but start with the timeout error
[00:26:19] <r00t4rd3d> maybe that other stuff needs active parport
[00:27:18] <andypugh> do you know that the manual addr_hi and epp_wide are needed?
[00:28:27] <Tom_L> ?
[00:28:49] <Tom_L> i changed the bios parport mode
[00:28:53] <Tom_L> still no go
[00:28:59] <Tom_L> refresh the link
[00:29:04] <Tom_L> for dmesg
[00:29:19] <r00t4rd3d> tail -f /var/log/dmesg
[00:29:31] <Tom_L> what does that do?
[00:29:49] <r00t4rd3d> shows errors in real time
[00:30:18] <r00t4rd3d> monitors the dmesg file for changes, when changes, errors, etc happen , prints them in the terminal window
[00:30:43] <r00t4rd3d> then you dont have to sift in a big file that you never seem to clear.
[00:31:12] <Tom_L> how do you clear it?
[00:31:22] <r00t4rd3d> select all , delete
[00:31:30] <r00t4rd3d> open it as root
[00:31:41] <r00t4rd3d> sudo gedit /var/log/dmesg
[00:32:35] <r00t4rd3d> just tail it though
[00:32:43] <r00t4rd3d> copy and paste the error
[00:33:41] <atom1> does the bit file need execute permissions?
[00:33:58] <r00t4rd3d> who knows but set it to yeah
[00:34:02] <r00t4rd3d> wont hurt
[00:34:32] <r00t4rd3d> what permissions does root have of it?
[00:34:41] <r00t4rd3d> read/write?
[00:34:47] <r00t4rd3d> modify i think
[00:35:22] <atom1> should root own it?
[00:35:31] <r00t4rd3d> probably
[00:35:46] <r00t4rd3d> its a system file that loads at boot?
[00:37:00] <r00t4rd3d> ROAR!
[00:43:14] <atom1> i think i found part of it
[00:49:25] <atom1> i think i the bit files are wrong, i need to copy them from my atom

[01:27:20] <Tom_L> mmm
[01:29:22] <Tom_L> says it's got the wrong firmware file for the 7i43 but i copied it from my working D525 pc
[01:29:50] <Tom_L> hm2/hm2_7i43.0: board has FPGA '3s200tq144', but the firmware in hm2/7i43-4/SVST2_4_7I47B.BIT is for FPGA '3s400tq144'
[01:29:55] <jdh> I got a similar message with a screwed u p-port
[01:31:02] <Tom_L> i changed the mode in the bios
[01:31:17] <jdh> that didn't help mine
[01:31:38] <Tom_L> afik it was a working parport, i've used it
[01:31:47] <jdh> for mesa? or just as a pport?
[01:32:04] <Tom_L> just as a parport
[01:32:11] <Tom_L> this is a new setup for mesa
[01:32:14] <Tom_L> on this pc
[01:32:25] <Tom_L> just trying to make it work since it was just sitting here
[01:32:27] <jdh> mine worked as a p-ort also. Wouldn't talk properly to th 7i43
[01:32:43] <Tom_L> what did you get as an add in?
[01:32:55] <jdh> I don't understand
[01:32:57] <Tom_L> i have some legacy parports but not for pci
[01:33:05] <Tom_L> they're all isa i think
[01:33:16] <Tom_L> did you use an add in parport card?
[01:33:21] <jdh> I think so
[01:33:23] <Tom_L> is what i was asking
[01:33:56] <Tom_L> i could look but i'm near 100% sure they're isa
[01:34:20] <jdh> I think I found a program that made it work, but I got the 525 about the same time and it might have just been that
[01:34:56] <jdh> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Startech
[01:36:13] <Tom_L> i may try the bios once more
[01:36:19] <Tom_L> set it to EPP instead of both
[01:42:09] <Tom_L> that helped a bit
[01:42:11] <Tom_L> i think

[01:43:04] -!- Keknom has quit [Quit: Leaving.]
[01:43:09] <Tom_L> <andypugh> do you know that the manual addr_hi and epp_wide are needed?
[01:43:16] <Tom_L> what did andy mean ?
[01:43:34] <jdh> you need the two addresses.
[01:44:04] <Tom_L> hm2_7i43.0: board at (ioaddr=0x0378, ioaddr_hi=0x0778, epp_wide ON) found
[01:44:04] <Tom_L> ?
[01:44:22] <jdh> that's them
[01:44:30] <Tom_L> i wonder why it quit then
[01:44:35] <Tom_L> it loaded the firmware
[01:44:55] <jdh> run it from a console window
[01:46:55] <Tom_L> nope
[01:47:16] <jdh> no additional error message there?
[01:47:27] <Tom_L> it wrote 2 files
[01:49:27] <Tom_L> http://tom-itx.dyndns.org:81/~webpage/cnc/linuxcnc_debug.txt
[01:49:29] <Tom_L> http://tom-itx.dyndns.org:81/~webpage/cnc/linuxcnc_print.txt
[01:50:50] <jdh> did you copy a 2.5 config to 2.4 or something?
[01:51:09] <Tom_L> 2.5 from my atom pc
[01:51:12] <Tom_L> no
[01:51:23] <Tom_L> i ran the update first per website
[01:51:29] <jdh> and you have 2.5 here?
[01:51:36] <Tom_L> it should be
[01:51:37] <jdh> how did you copy the config over?
[01:51:43] <Tom_L> i updated it
[01:51:51] <Tom_L> thumb drive
[01:52:04] <jdh> looks like it doesn't like your ini
[01:53:54] <Tom_L> mmm
[01:53:58] <Tom_L> it runs on the other pc
[01:54:33] <jdh> without the warnings?
[01:54:47] <Tom_L> yes
[01:54:47] <Tom_L> runs fine
[01:55:02] <jdh> might try tar'ing up th config again and copy it that way
[01:55:29] <Tom_L> the parport should be ok now you think?
[01:55:37] <Tom_L> if it loaded the firmware files

[01:57:26] <jdh> dmesg looks the same as mine
[01:58:51] <Tom_L> i'm gonna run some updates and see what happens
[01:59:06] <Tom_L> i got a message about some timing thing being 'tainted'
[01:59:51] <jdh> that's nothing
[01:59:59] <Tom_L> i'm gonna switch the parport back to both and change the dma channel and see what happens
[02:00:07] <Tom_L> probably will break it again
[02:00:23] <jdh> why both
[02:01:06] <Tom_L> i think that's how the other one is set
[02:01:36] <Tom_L> i'm not entirely positive though
[02:01:58] <jdh> it only wants epp
[02:03:30] <Tom_L> nope, it didn't like that at all
[02:04:14] <Tom_L> yeah i just wanted to confirm it
[02:04:26] <Tom_L> i think that part is ok now
[02:07:05] <Tom_L> rtapi: no version for nano2count found: kernel tainted
[02:07:09] <Tom_L> was the message
[02:07:30] <jdh> that's nothing
[02:09:23] <Tom_L> i'm gonna run the updates and see what happens
[02:10:19] <Tom_L> i'm not sure what else it could be
[02:10:31] <jdh> what else what can be?
[02:10:35] <Tom_L> unless there's something about the parport it doesn't like
[02:10:39] <Tom_L> why it won't run
[02:10:54] <jdh> Can not find -sec MOT -var MOT -num 1
[02:10:54] <Tom_L> it loads the config
[02:11:16] <Tom_L> oh
[02:11:32] <Tom_L> maybe that's some halui stuff i added and forgot to copy
[02:11:40] <Tom_L> i bet
[02:12:15] <Tom_L> i thought i got all the files i needed

[03:26:52] <pcw_home> Tom_L: if the 7I43 loaded the firmware, its time to stop messing with the parallel port

[03:29:52] <JessicaRN> r00t4rd3d: Thanks for your help last week. my first cut on the machine was a great success. That sun figure looks amazing.
[03:31:42] <ReadError> awww
[03:31:48] <ReadError> you didnt cut "Y U NO" guy?
[03:33:19] <r00t4rd3d> :) glad it worked out for you, got a pic?
[03:34:35] <JessicaRN> err... nope, not yet. my test cut was on foam. I'm gluing up a wood blank tomorrow and I'll make the final out of that. I'll post a pic when I do.
[03:35:18] <JessicaRN> cut3d worked like a champ. so far I can't find any downside to that app.
[03:36:08] <jdh> the price?

[03:36:41] <JessicaRN> lol... yeah, well there is that
[03:40:04] -!- Tom_L has quit []
[03:41:15] <Tom_itx> pcw_home why would it load the firmware then quit?
[03:41:34] <JessicaRN> anyone every used a touch probe to create a point cloud? how does one turn a point cloud into a .stl or other solid model?
[03:42:03] <Tom_itx> pcw_home that's what has me stumped right now
[03:42:25] <Tom_itx> pcw_home, http://tom-itx.dyndns.org:81/~webpage/cnc/dmesg_text.txt
[03:43:24] <pcw_home> so its a higher level error 7I43 comms are fine
[03:43:46] <Tom_itx> i copied all the config files from a working pc
[03:44:15] <pcw_home> did you run it in a terminal (some errors are only listed there)
[03:44:19] <taiden> JessicaRN: if you can find the answer to that please let me know
[03:44:52] <JessicaRN> *smiles*
[03:45:01] <Tom_itx> i tried that once as well
[03:45:19] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/linuxcnc_debug.txt
[03:45:21] <JessicaRN> i'll prolly end up making my own probe.

[03:46:30] <pcw_home> But neither of those are a terminal log
[03:46:53] <taiden> soo
[03:47:00] <taiden> junk pc my friend gave me today
[03:47:04] <pcw_home> are you saying it says nothing if run from a terminal?
[03:47:13] <taiden> 11k/12k full load for 4 hours
[03:47:24] <taiden> glxgears and do loop
[03:48:22] <Tom_itx> pcw_home, the terminal run generated those last 2 files i posted
[03:48:27] <taiden> 8.04 with 2.5.x update and no tweaks
[03:49:33] <pcw_home> I dont mean the generated files, rather what is printed in the terminal when LinuxCNC exits
[03:49:47] <JessicaRN> what kind of bit do you need to cut aluminum with a router? Is it even possible, or is the spindle too fast?
[03:50:51] <taiden> seems like most end mills are actually for metal
[03:51:00] <taiden> some routers go real slow
[03:51:09] <Tom_itx> pcw_home, just a sec
[03:51:09] <taiden> mine does ~8k at the slowest
[03:52:48] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/terminal.png
[03:53:04] <JessicaRN> is there a decent speeds and feeds reference for hobby mills with routers?
[03:53:21] <Tom_itx> pcw_home, maybe it's the spindle encoder?
[03:53:49] -!- zlog has quit [Ping timeout: 252 seconds]
[03:54:19] <pcw_home> thats the error (encoder.01.counter-mode)

[03:59:24] <pcw_home> the problem is that you only have one encoder enabled but are asking for the second encoder

[04:00:59] geo01005_ is now known as geo01005
[04:01:29] <atom1> this config works fine on my D525 atom
[04:02:17] <atom1> the first encoder is the MPG
[04:02:32] <atom1> the 2nd is a single input encoder on the spindle
[04:03:48] <pcw_home> Well thats strange because dmesg only shows one encoder
[04:04:04] <atom1> i'll tackle it more tomorrow
[04:04:27] <atom1> but it's the same file set that i pulled from my working D525
[04:04:29] <Jymmm> Why would I use 302 over 304 ?
[04:05:19] <Jymmm> I'm dealing with high heat fwiw
[04:06:07] <pcw_home> same bitfile?
[04:06:12] <Tom_itx> yes
[04:06:39] <Tom_itx> i will copy them all over fresh tomorrow
[04:06:43] <Tom_itx> and try again then
[04:06:50] <pcw_home> Is this consistent? same error in terminal?
[04:07:05] <pcw_home> if launched over and over
[04:07:39] <atom1> yes
[04:08:32] <pcw_home> You could try eliminating the num_encoders stuff so it enables them all
[04:08:58] <Tom_itx> i'll comment that out and try it tomorrow
[04:09:52] <Tom_itx> at least i have a few things to look for now

[14:31:21] <jdh> there is a wiki entry for joypads (or two)
[14:31:41] <ktchk> the .hal file is for 2.4 not 2.5
[14:35:09] <taiden> i just copied over a backed up linuxcnc folder
[14:35:23] <taiden> how do i create the shortcut to open my machines configuration?
[14:35:55] <jdh> ktchk: might see if this helps: http://www.linuxcnc.org/index.php/english/component/kunena/?func=view&id=19139&catid=9
[14:36:31] <taiden> nvm i got it
[14:36:37] <jdh> taiden: you can make it by hand, or if you run linuxcnc from the menu, the configuration picker should have a checkbox in the lower left for shortcut
[14:36:52] <taiden> thanks, that's what it was :)
[14:38:52] <taiden> i need to edit my latency numbers, are they located in .hal?

[14:40:44] <jdh> I have a $7 joypad coming from china to try out.
[14:41:05] <jdh> the shuttlexpress jog shuttle thingie works pretty well for jogging though.
[14:43:03] <skunkworks> a normal jog wheel is imho the best :)
[14:44:00] <jdh> the shuttlexpress can be a normal jog wheel
[14:44:34] <skunkworks> I thought those where pretty low count per rev - like 10 or 20
[14:44:56] <skunkworks> they look neat
[14:44:59] -!- tjb1 has quit [Ping timeout: 244 seconds]
[14:45:10] <jdh> you can step through incremental jog rates, or use the analog jog for varying speed
[14:45:44] <jdh> I think it is only 10 counts
[14:46:11] <taiden> i copied my old linuxcnc folder over, but i get unexpected realtime delay errors now
[14:46:28] <archivist> taiden, a latency killer for me, open a large txt in gedit and grap the scroll bar and scroll the text
[14:46:29] <taiden> having trouble locating in the docs where the latency numbers are stored in .hal or .ini or otherwise
[14:46:30] <ktchk> jdh: thanks but not what i needed

[14:48:35] <skunkworks> taiden, the latency numbers don't do anything in the hal files. It might calculate the base period for you. But the base period is what you want to look at.
[14:50:25] <ktchk> need the some thing like "net joy-x-jog halui.jog.0.analog <= input.0.abs-x-position" example

[14:56:56] <ktchk> pins name connect to button table is needed

[14:59:18] <taiden> any thoughts?
[14:59:41] <taiden> too fast stepper rpm for my base period?
[15:00:08] <skunkworks> taiden, that would be my guess

[17:52:01] <cpresser> IchGuckLive: that does not depent on Ids, but rather on how fast you want to switch (gate capacity)
[17:52:42] <pcw_home> Also if AVR is 3.3V you need a logic level MOSFET

[17:56:25] <Loetmichel> and the avr is 5V
[17:56:37] <Loetmichel> why shoud i use it with 3.3V without need?
[17:57:07] <pcw_home> I forget that 5V chips still exist
[17:57:27] <IchGuckLive> 5V is popular in Europ
[17:57:49] <Loetmichel> pcw_home: all 8 bit avr can operate at 5V
[17:57:50] <IchGuckLive> i only went 3.3 for the astro stuff
[17:58:16] <Loetmichel> and most at 3,3V with lower clock
[17:58:26] <cpresser> 5V it is for DIY-Stuff, most professionals use 3.3V for new µC-Designs
[17:58:32] <pcw_home> Industrial stuff is usually 5V min (not many 3.3V encoders for example)
[17:58:54] <pcw_home> latest FPGAs dont even do 3,3
[17:59:16] <pcw_home> 3.3 is the new 5
[17:59:19] * cpresser had to buy some 1.8V LDOs :)
[17:59:25] <Loetmichel> cpresser: again: why should i use 3,3V if i have 12V supply and the 5V fets are much more common than 3.3V types?
[17:59:51] <cpresser> Loetmichel: i didnt say that. for most designs in that area 5V is fine
[18:00:10] <pcw_home> For simple things , no reason but if you need speed you will find no 5V chips
[18:00:22] <Loetmichel> pcw_home: speed?
[18:00:25] <cpresser> i also do some applications with Lowside FETs attached directly to the µC (@5V)
[18:00:28] <Loetmichel> in an 8bit avr?
[18:00:47] <pcw_home> In general
[18:01:15] <pcw_home> AVRs use ancient design rules (80s?)
[18:01:34] <IchGuckLive> Lowside FETs any numbers on that to buy
[18:01:51] <Loetmichel> why should i shoot with cannons on sparrows?
[18:02:15] <IchGuckLive> i usa also 5V AVR in all aplications
[18:02:22] <pcw_home> Just saying in general 5V is (slowly) going away
[18:02:25] <IchGuckLive> most Mega8
[18:02:35] <Loetmichel> a Avr tiny 2313 IS old... but cheap and perfectly fit for some PWM and speed regulation.
[18:02:40] <Loetmichel> ... AND at hand ;-)
[18:03:00] <DJ9DJ> nearly as old as you are *searching cover and hiding*
[18:03:03] <DJ9DJ> ;-)
[18:03:24] <pcw_home> the more heat sinking the cheaper the FET
[18:03:25] <Loetmichel> DJ9DJ: not even remotely
[18:03:30] <Loetmichel> i am MUCH older ;-)
[18:03:31] <IchGuckLive> Loetmichel: FET name Available at reichelt ?
[18:04:00] <DJ9DJ> hihi
[18:04:05] <Loetmichel> have none, will use some from another project
[18:04:14] <IchGuckLive> ok
[18:04:43] <cpresser> "IRF540" will work fine with a avr for Lower Frequencys
[18:05:38] <pcw_home> If you have a heat sink and can afford some power dissipation you can use a higher Ron
[18:05:40] <pcw_home> and thus get better speed (since it will have lower gate /miller capacitance)
[18:05:44] <Loetmichel> wil use an IRLR7843
[18:05:55] <Loetmichel> but the IRF5490 will do fine, as cpresser said
[18:06:22] <IchGuckLive> thanks
[18:06:23] <Thetawaves> are you sure the avr can source enough current to directly drive the irf540?
[18:06:27] <Loetmichel> 540
[18:06:43] <pcw_home> What PWM frequency?
[18:06:49] <Thetawaves> i always put a transistor in the middle to speed up switching of the mosfet... generates less heat
[18:06:57] <Loetmichel> Thetawaves: if your pwm stays below 20khz: sure!
[18:07:16] <pcw_home> what is the MOSFET driving?
[18:07:31] <cpresser> Thetawaves: my application switches with 200Hz only, thats almost DC :)
[18:08:35] <Thetawaves> even at 200hz, if your mosfets stay in transition mode too long, you'll be able to fry eggs
[18:08:54] <Loetmichel> pcw_home: i think IchGuckLive wants to copy that: http://www.cyrom.org/palbum/main.php?g2_itemId=12846
[18:09:30] <pcw_home> DC spindle control?
[18:09:36] <IchGuckLive> yes
[18:10:07] <Loetmichel> Thetawaves: an AVR can source about 30mA and sink about 50. no need for a mosfet driver below 20khz PWM

[19:16:42] <pcw_home> micges: Ive been pounding on the 7I80b Ethernet and it seems pretty good for a Beta
[19:16:44] <pcw_home> BootP works and I added the random TID its supposed to have so other than some testing
[19:16:46] <pcw_home> and perhaps performance tweaking it seems OK to release
[19:17:10] <skunkworks> pcw_home, that sounds very cool!
[19:17:38] <micges> pcw_home: that's great
[19:17:38] <skunkworks> I assume it take daughter boards of some kind?
[19:17:46] <pcw_home> Yet another connect method for HM2
[19:17:53] -!- gmagno [gmagno!~gmagno@a213-22-30-249.cpe.netcabo.pt] has joined #linuxcnc
[19:18:56] <pcw_home> Yeah the current card (7I80DB) uses the DB25 daughtercards (up to 4)
[19:18:58] <pcw_home> but theres a 7I80HDR for 50 pin daughtercards coming
[19:20:03] <pcw_home> (with 3 connectors)
[19:20:19] <Jymmm> pcw_home: Didn't 50pin anything go out with rotary business phones and SCSI way back in the last century? <ducks>
[19:20:52] <pcw_home> Well people still use the OPTO22 stuff
[19:21:07] * skunkworks raises hand
[19:21:11] <micges> and 7i40
[19:21:31] <Jymmm> pcw_home: JUST teasing =) Though it is nice (if you can find them) to be able to use old scsi cables
[19:21:56] * Jymmm smacks skunkworks hand with panduit!
[19:22:27] <Jymmm> (cover not included)
[19:22:37] <pcw_home> Yeah and 7I29 and 7I49 and 7I30 (though we will have more SSerial interfaced drives this year)
[19:23:26] <pcw_home> and 7I39
[19:24:22] * Jymmm received packaging and ink samples and is just bouncing around all giddy like!
[19:25:07] <skunkworks> pcw_home, is the hm already setup to do eithernet?
[19:25:15] <skunkworks> hm2
[19:26:17] <pcw_home> Well the easy part is done (Ethernet --> UDP --> LBP16 --> HM2)
[19:27:33] <skunkworks> what kind of roud trip times are you getting?
[19:27:40] <skunkworks> round
[19:27:48] <pcw_home> the hard part is integrating a real time polled Ethernet driver in to HAL (and then the fairly simple task of packing and unpacking the commands)
[19:28:24] <skunkworks> that is pretty cool - realtime control of the eithernet attached device. Impresive
[19:28:27] <Jymmm> pcw_home: Is that via a crossover cable? a hub? a switch?
[19:28:38] <pcw_home> for normal 4/5 axis sized stuff its in the 70 Usec region
[19:28:56] <pcw_home> Faster than the 7I43/ slower than the PCI cards
[19:29:03] <skunkworks> right
[19:29:27] <pcw_home> The PHY is MDIX so any cable works
[19:29:47] <skunkworks> neat
[19:29:49] <Jymmm> pcw_home: Not cabling, but switching for the RT stuff
[19:29:57] -!- vladimirek has quit [Ping timeout: 248 seconds]
[19:30:05] <Jymmm> pcw_home: VPN and all that
[19:30:27] <pcw_home> Normally you would use a dedicated port so switches are not an issue
[19:30:52] <Jymmm> pcw_home: dedicated how? hub/switchless?
[19:31:06] <pcw_home> point to point
[19:31:30] <pcw_home> If its real time you cant have other traffic
[19:31:45] <Jymmm> pcw_home: Ok, so if need 500ft, you could NOT use a switch to extend the length.
[19:31:55] <Jymmm> err 500m
[19:31:59] <cpresser> switches also do store/forward, you don want that
[19:32:15] <Jymmm> cpresser: That why I asked, but a hub doesn't =)
[19:32:17] <Connor> jdh: Got my solenoid valves, fittings, and tubing in today!
[19:32:20] <cpresser> Jymmm: media-converter -> fiber optics
[19:32:24] <pcw_home> Sure you could but it would increase the turnaround time
[19:32:44] <pcw_home> Are hubs even made anymore?
[19:32:50] <Jymmm> pcw_home: yes
[19:33:13] <Jymmm> cpresser: no emi/rfi either
[19:33:31] <Jymmm> cpresser: 30KM range too =)
[19:33:51] <pcw_home> so that would work
[19:34:11] <Jymmm> cpresser: I have a 5 seconds fiber delay box =)
[19:34:33] <Jymmm> maybe 3s
[19:34:35] <cpresser> depending on the environment, fiber-optics is superior to RJ45 in terms of durability
[19:34:53] <Jymmm> but not for short runs
[19:35:11] <Jymmm> cost is just too high
[19:35:13] <cpresser> at least for professional sound-systems & PA the guys prefer fiber over copper nowadays
[19:35:28] <Jymmm> I can see that, long runs too
[19:36:17] <micges> I saw fiber on very large Okuma mill
[19:36:43] <micges> cables were much more than 15m
[19:38:54] <L84Supper> we worked with FCI back in the late 90's to make single mode fiber connectors for tablets used in aerospace MRO, durability was in the few k's of plug and unplug
[19:39:26] <L84Supper> are these common now or do most apps just use copper?
[19:41:11] <pcw_home> Much fewer EMI issues if you can afford it
[19:41:13] <pcw_home> Theres a connectorless fiber system we looked into for SSerial: Optolock?
[19:41:15] <pcw_home> The transmitters and receivers still made it pretty expensive
[19:41:52] <Jymmm> pcw_home: why not the S/PDIF connectors?
[19:42:18] <Jymmm> unconventional, bot plentiful
[19:42:24] <Jymmm> but
[19:43:04] <Jymmm> I'm sure some kind of locking system could be added

[20:11:27] <jdh> am now.
[20:11:35] <andypugh> pcw_home: It doesn't use anything at the moment, but if I get it working it won't use any external HAL components.
[20:11:56] <Jymmm> Guys, I got a question... If a container intended for retail packaging of a product costs $0.70/ea and a seal to prevent tampering on the shelf cost $0.17/each, Would you add the seal?
[20:12:20] <andypugh> It looks in a dedicated are of shared-memory for pre-processed image data, and reads it direct.
[20:12:32] <Jymmm> The seal is NOT required to maintain the integrity of the contianer.
[20:12:36] <Thetawaves> Jymmm, what is the rate of theft without the seal?
[20:12:45] <andypugh> I wouldn't.
[20:13:08] <Jymmm> Thetawaves: Theft, zero. Open the contiainer on the shelf, probably high.
[20:13:24] <Jymmm> ^to get a better look at the product.
[20:13:25] <Thetawaves> whats wrong with that?
[20:14:11] <jdh> if it is non-cheap and I want to see it first, I'm opening it.
[20:14:18] <Jymmm> It's a consumable product that could (somewhat) leak. Think playdough or lotions.
[20:14:26] <jdh> then, I'll put it back on the shelf and buy a sealed one.
[20:14:34] <Thetawaves> oh, in that case you should seal it
[20:14:41] <pcw_home> We have a customer that needs something similar (thou maybe with gcode paths)
[20:14:43] <pcw_home> I was thinking the data could be painted out with the sqrt(X^2+Y^2) velocity from the encoders
[20:14:56] <Jymmm> then you have the PITA like jdh
[20:15:12] <Thetawaves> yeah, display a sample :D

[20:16:15] <Jymmm> can't do that, but if like jdh mentality, why would you break a seal, look at soemthing, know it good/working order, then put it back just to grab one that "SHOULD" be in working order, but not verified.
[20:16:16] <pcw_home> (with the ability to use a hardware FIFO for higher modulation rate if need be)

[20:16:59] <jdh> I'm usually the other kind.
[20:17:13] <Jymmm> other?
[20:17:28] <Jymmm> bad example?
[20:18:03] <Jymmm> the container is clear fwiw
[20:20:00] <Jymmm> I"m just not sure if it's worth it or not to add a 25% markup for the seal plus the time and labor to apply it.
[20:21:19] <Jymmm> It's not for purposes of safety, just ppl on the shelf messing with it.

[22:12:50] <Tom_itx> andypugh what are you working on?
[22:13:26] <andypugh> At the moment, a problematic gantrykins config from the forum.
[22:14:36] <Tom_itx> how do you describe the tool tip of a touch probe to linuxcnc so you get accurate surface probing?
[22:14:49] <Tom_itx> all you have in the tool table is the diameter
[22:15:17] <Tom_itx> i suggested the other day maybe it needs a tip diameter entry in the table as well
[22:15:32] <andypugh> You can't
[22:15:38] <Tom_itx> so it can adjust the geometry approach on a surface
[22:15:54] <andypugh> LinuxCNC has no idea where the surface has touched the tip,
[22:16:27] <andypugh> So can't do the calculation you are asking for.
[22:16:35] <Tom_itx> it knows the direction of travel
[22:16:42] <andypugh> And?
[22:16:46] <Tom_itx> if it knew the sphere shape it could
[22:17:12] <Tom_itx> i'm not saying it would be easy or maybe not worth the effort
[22:17:14] <andypugh> I disagree. Consider probing a near-vertical surface vertically.
[22:17:46] <Tom_itx> our cmm had different modes for probing
[22:17:55] <andypugh> I think you could post-process the point-cloud, because then there is more shape data.
[22:18:15] <Tom_itx> the points could be off the diameter of the probe tip though
[22:18:37] <andypugh> But there are an infinite number of points on the probe tip.
[22:19:03] <Tom_itx> so are you better off probing with a pencil tip point?
[22:19:19] <andypugh> For 3D surfaces, I think you are.
[22:19:32] <Tom_itx> does probing read the tool diameter in the tool table?
[22:19:40] <Tom_itx> if you enter it as a tool
[22:19:46] <andypugh> Length, I think.
[22:19:53] <Tom_itx> but not diameter?
[22:20:08] <andypugh> It will read the diameter, but unless you probe in G42, it will ignre it.
[22:20:53] <Tom_itx> maybe in that case a flatbottom small diameter tip would be most accurate
[22:20:58] <andypugh> If you probe with a ball the exact diamter of your ball-nose cutter and perform no other compensations you will get a perfect copy, though.

[23:23:56] <andypugh> You could just call a probe subroutine after tool-change, or you can remap M6 to do the whole probing thing automatically.
[23:24:28] <joe9> oh, cool. will check out M6. thanks.
[23:24:38] <andypugh> Do I mean M6?
[23:24:52] <Tom_itx> yes that's tool change
