[14:21:49] <R2E4> What is involved in creating a linuxcnc sim? Can I install it from the live cd and then upgrade/change?
[14:30:00] -!- Jeebiss has quit [Ping timeout: 245 seconds]
[14:30:37] <FinboySlick> R2E4: Technically, you don't have to install it, you can run it straight from the livecd.
[14:31:00] <FinboySlick> (or at least you could last time I played with the livecd)
[14:32:10] <R2E4> The simulator?
[14:33:09] <FinboySlick> I'm not familiar with the simulator bit.
[14:33:34] <R2E4> I would rather install it. I found the docs for building it. I have the real linuxCNC in the shop now connected to my control panel so I wont be able to work on it dureing the day, so at work I would like to test and program in a simulator enviroment.
[14:36:50] <archivist> I have played with it straight from the livecd too
[14:41:05] <R2E4> I have the computer and 7i77 installed on control panel and wiring ins and outs. THats a long process to make it nice and neat
[14:42:52] <R2E4> Can I install linuxcnc from live cd then compile the Linuxcnc SIM on top of it?

[15:12:13] <cradek> sim can mean two things: a nonrealtime build of linuxcnc that doesn't require a special kernel, or a config that does not control any hardware
[15:12:40] <cradek> you can certainly install or just boot the livecd, and then run any of the sim configs
[15:13:09] <cradek> or, if you already have a normal nonrealtime linux machine, you can install our sim-built debs or build a sim mode linuxcnc for yourself
[15:22:19] <R2E4> So the linuxcnc install from the Livecd will work if using sim configs?
[15:24:57] -!- terabyte- has quit [Quit: terabyte-]
[15:25:10] <cradek> yep it'll work fine
[15:26:34] <R2E4> Whats the diff if you build it with --enable-simulator or from live CD?
[15:26:59] <cradek> --enable-simulator causes a build that doesn't need a realtime kernel
[15:27:09] <R2E4> ok
[15:27:17] <cradek> or you can use the -sim debs; you don't have to build it
[15:27:43] <R2E4> I'm installing now from livecd so I'll just locate the sim configs
[15:31:24] <R2E4> cradek: Is there a document that outlines the basic logic process for linuxcnc with 3 axis machine or any of that matter/ Re: powerup, e-stop set before power up, Drive(axis) ready before power machine on, etc...?
[15:32:43] <R2E4> I'm getting close to interfacing with the drives, and want the logic setup before.
[15:32:51] <archivist> have you looked at the integrators manual
[15:32:56] <cradek> I'm not sure. Some of those things are going to be different based on your machine's needs
[15:34:23] <R2E4> I'll gander through the integrators manual and see if theres a generic basic process.
[15:35:04] <R2E4> Normally do you have an input "Drive Ready" before you enable the drives?
[15:35:11] <cradek> it's hard to write overview-type docs, we'd rather answer specific questions
[15:35:14] <R2E4> and if not dont enable?

[15:44:58] <pcw_home> depending on the drives you may not get drive ready unless you enable the drives
[15:45:11] <R2E4> IS there some kind of indication in axis, or should I do that with a lite on panel?

[15:47:13] <pcw_home> (Fanuc is like that)
[15:47:35] <pcw_home> (disabled is a fault)
[15:47:39] <cradek> sometimes getting boostrap can be tricky. especially if each device's fault output can disable all the other devices (like if you want amp fault to disable the spindle vfd, and also vfd fault to disable the amps)
[15:48:09] <R2E4> pcw_home: Mounted 7i77 on panel last nioght and started wiring..... coming along nicely untill I powered up an no lites on 7i77. So I quickly shut off power and realized I wired power in backwards cause I installed the 7i77 upside down.
[15:48:46] <cradek> yikes
[15:48:51] <R2E4> yeah, thats why I was looking for logic scenario..... hehe
[15:49:10] <R2E4> I corrected the polarity and all is well.
[15:49:17] <cradek> that's some stout hardware
[15:50:01] <R2E4> I thought for sure I blew it up. Its solid.....
[15:50:35] <pcw_home> It has protection diodes (but there are always ways)

[15:52:33] <pcw_home> (field power switching regulators blown, rated at 50V in customer says only 24V)
[15:52:49] <archivist> I used to repair kits that our customers had built, I have seen some customer caused problems too
[15:52:57] <pcw_home> maybe no output capacitor on PS
[15:53:26] <CaptHindsight> spikes to >100V for several uS might be enough to do it
[15:53:34] <pcw_home> yep
[15:53:52] <archivist> I had all the gnd track blown off one board
[15:54:21] <CaptHindsight> people think automotive is only 12V but on older cars it would easily spike to >50V
[15:54:47] <pcw_home> we had someone blow up a series of 7I29s (no PS output capacitor)
[15:54:48] <archivist> only 50 :)
[15:54:51] <Jymmm> pcw_home: 120VAC --> [24V Sec / 120 Pri ] --> 600VAC =)
[15:56:17] <pcw_home> just a normal 24V control transformer into a bridge will generate really large spike if turned off at max current
[15:57:39] <CaptHindsight> If there is a way to hook something up wrong people will find a way
[15:57:56] <Jymmm> pcw_home: Heh, I remember talking to Marriss once about his "Vampire" (you can't kill them) drives.... Guarantee to kill them by unplugging motors while energized =)
[15:58:55] <R2E4> My 24v power supplie when shutoff shuts off, the relay clicks and red lite follows the click. Should I attempt to fix that?

[16:00:07] <pcw_home> well arcs are really nasty (charge up wiring capacitance with stored inductive
[16:00:08] <pcw_home> energy and then you get a picosecond rise time HV spike )
[16:00:36] <R2E4> 24vdc power supplies, when I remove AC power, dc stays in the caps, the ac fail and batt fail relay cycles causing dc spike

[16:05:18] * JT-Shop discharges caps with his finger usually
[16:05:26] <kbarry> Poplar seemed too coft to make clean cuts, and the whole thing was very very fuzzy,

[16:06:22] <archivist> kbarry, blunt cutters/spindle not fast enough ?
[16:06:37] <kbarry> Looking for recommendations for 3d carving wood, paint gradable.
[16:06:38] <Jymmm> kbarry: Use a scotchbright (kitchen green) pad to remove the fuzzys
[16:06:48] <kbarry> Jymmm: well, i thought that might be the case, except it cut fine in alder,
[16:07:00] <Loetmichel> CaptHindsight: the light is a circuit that will choke the engine.
[16:07:05] <R2E4> kbarry, babmoo is amazing
[16:07:16] <archivist> also was the wood green or dried
[16:07:17] <kbarry> Well, its for a client, not myself,
[16:07:23] <R2E4> sands easy and carves really nice.
[16:07:26] <kbarry> It was dried
[16:07:33] <Loetmichel> its just to inform jou that the wheels would have made a burnout if the electronics would not have intervened

[16:09:34] <Jymmm> a what?

[16:11:40] -!- jeremy79 [jeremy79!~jeremy@] has parted #linuxcnc
[16:11:51] <kbarry> jdh with MDF how would you recommend i clean it up?
[16:11:53] <Jymmm> jdh: The issue is that MDF can't be painted where it has exposed edges
[16:12:08] <kbarry> I always get fuzzies, and its difficult to clear them without sanding down details.
[16:12:23] <jdh> Jymm: why not?
[16:12:37] <jdh> good sealer first
[16:13:24] <Jymmm> jdh: Sealers dont work either. IT's like a sponge. The surfaces are compressed to 120PSI, but no thte "meat"
[16:13:26] <R2E4> MDF is nice to work with. I use sealer, and a clear coat, same stuff they use on cards.
[16:13:45] <Jymmm> Yeah, bondo is the only way
[16:14:07] <Jymmm> but with the intricate detailed of a 3D carving, I doubt it would fill properly
[16:14:58] <Jymmm> Well, ok, you can paint it with black (eventually), but that's about it for some odd reason.
[16:15:56] <Loetmichel> Jymmm: MDF can be painted perfectly
[16:16:08] <Jymmm> Loetmichel: not the edges
[16:16:12] <Loetmichel> you just have to use so much paint that it gets soaked
[16:16:13] <Loetmichel> ;-)
[16:16:25] <Jymmm> surface sure, it will even take a thread and hold it well
[16:17:20] <Jymmm> I spoe to one ot the guys in the lab at a MDF Mill is the only reason I know about bondo
[16:17:22] <Loetmichel> and use a 2component paint if you want it to dry eventually ;-)
[16:17:36] <Jymmm> epoxy?
[16:17:49] <Loetmichel> car paint works well
[16:18:02] <Jymmm> the epoxy paint would cost you more than the raw material
[16:18:14] <Loetmichel> it does ;-)
[16:18:16] <R2E4> http://irmtl.com/cnct/pics/molspn.jpg mdf painted rusic kind of
[16:18:17] <Jymmm> at that rate, sign foam would be cheaper

[16:19:28] <R2E4> The edges are an issue with mdf though
[16:20:01] <Jymmm> except for black

[16:29:46] <Loetmichel> but its great for making molds BECAUSE it has no "fibre orientation"
[16:30:14] <Loetmichel> or for making a sacrificial plate on the mill

[18:14:59] <tehcereal> its only 3 l293ds and some resistors and switches
[18:15:17] <tehcereal> the motors are week
[18:15:20] <IchGuckLive> i see

[18:16:30] <tehcereal> nothing serious
[18:16:41] <tehcereal> it needs just to move
[18:16:42] <tehcereal> haha
[18:16:43] <IchGuckLive> so you need to put 1 more IC infrotz of the L293
[18:17:49] <tehcereal> to get step/dir
[18:17:51] <tehcereal> ?
[18:17:55] <IchGuckLive> yes
[18:17:58] <archivist> tehcereal, you just need to change the stepper type and configure the pins
[18:18:07] <tehcereal> i thought that
[18:18:22] <archivist> bit of hal tomfoolery
[18:18:32] <IchGuckLive> archivist then he needs all 12 outputs
[18:18:47] <archivist> I know, add another parallel port
[18:18:51] <tehcereal> type 10 would be good i guess
[18:19:31] <tehcereal> why another parallel port
[18:19:43] <archivist> for a "getting to know" it will work but not the right way for real work
[18:19:53] <IchGuckLive> tehcereal: http://www.datasheetcatalog.com/datasheets_pdf/L/2/9/7/L297.shtml
[18:20:04] <IchGuckLive> this woudt do the job for you
[18:20:30] <IchGuckLive> then you also get enable pins for Now extra cost
[18:20:52] <tehcereal> doesn't the parallel portss have 12 output pins
[18:21:13] <tehcereal> but some are inverted
[18:21:17] <archivist> cant remember how many can be out
[18:21:22] <IchGuckLive> tehcereal: Why did you build your wn and not going to use a TB6560 3Axis all in one board for 25Euros

[18:22:11] <tehcereal> we cant buy anything else
[18:22:16] <tehcereal> just raw chips
[18:22:19] <IchGuckLive> tehcereal: but then you run out of pins with your system
[18:23:06] <IchGuckLive> then if raw chips go for L296/297 Combination for your layout
[18:23:07] <ktchk> TB6560 have raw chips
[18:23:18] <IchGuckLive> hi to HK
[18:23:24] <IchGuckLive> how is the weather
[18:23:26] <ktchk> Hi
[18:23:32] <ktchk> cold
[18:23:36] <Loetmichel> and tb6560 are MUCH easier to interface
[18:23:49] <CaptHindsight> Jymmm: that's what Bondo is. unsaturated Polyester + talc, clay etc
[18:24:05] <Loetmichel> but ai bit more "wimp" when it comes to loose contacts/overvoltage and stuff
[18:25:16] <tehcereal> we considered about TB6560
[18:25:54] <tehcereal> but their price is the price is higher
[18:26:07] <IchGuckLive> so go for the L297
[18:26:13] <IchGuckLive> 38cent
[18:26:49] <tehcereal> we will do the l297/296 combo if the l293 fails :D
[18:27:02] <tehcereal> we have teams of 2
[18:27:14] <tehcereal> and the cheapest hardware
[18:27:33] <IchGuckLive> L297/L298 !!!
[18:27:35] <tehcereal> wins
[18:27:39] <tehcereal> :D
[18:27:45] <tehcereal> ok ok :D
[18:27:54] <IchGuckLive> 4,5Euros combi but the TB6560 is also on 4Euros
[18:28:39] <tehcereal> but im sure lot of my friends in other teams wil go the l297 combo
[18:28:41] <IchGuckLive> up to you to waste all the pins
[18:29:10] <tehcereal> all it need it to be functional and the cheapest hardware wins
[18:29:46] <IchGuckLive> then china is your friend HK will sell it to you for 15USD
[18:30:12] <ktchk> TB6560 from china is Yuen 11 us$2.00 http://item.taobao.com/item.htm?spm=a230r.1.14.35.XJsYfV&id=14718754978
[18:30:38] <IchGuckLive> oh you bastard you told me 3USD
[18:30:40] <tehcereal> yeah taobao :D but how can i get it from there
[18:30:51] <ktchk> new price
[18:30:56] <IchGuckLive> O.O
[18:31:01] <tehcereal> you own a store ktchk?
[18:31:16] <ktchk> No but I can help
[18:31:46] <IchGuckLive> tehcereal: where are you located then i can send you one
[18:31:56] <tehcereal> croatia
[18:32:03] <IchGuckLive> oh thats far
[18:32:14] <tehcereal> far far away :D
[18:32:16] <IchGuckLive> ask HK for fast delivery
[18:32:21] <ktchk> How many needed
[18:32:35] <tehcereal> 3 i guess
[18:32:57] <ktchk> ok email me
[18:33:05] <IchGuckLive> tehcereal: there are 3 axis on one board
[18:33:50] <ktchk> some single axis board is us$10
[18:34:26] <IchGuckLive> ktchk: i think he needs to build his own board around

[20:31:12] <Tom_itx> i've read the docs but it doesn't make a whole lot of cents
[20:32:56] <skunkworks> like this? http://electronicsam.com/images/emco/linuxcnc_configs/Latest/Half-fullstepMorph/emco-lathe.hal
[20:33:55] <skunkworks> :) I don't know if you should ask me to explain that...
[20:34:27] <skunkworks> it switches between 2 differentstep gens... one half stepping - one full stepping
[20:34:56] <Tom_itx> seems the 2 functions are quite similar
[20:35:23] <Tom_itx> the syntax was mainly what i was after
[20:36:29] <Tom_itx> what function does 202 equate to?
[20:38:15] <Tom_itx> and is 202 a hex or decimal value there?
[20:39:04] <CaptHindsight> carbon fiber brushless gimbal shows up today, looks good but not docs included, you have to search for all the drivers, applications and firmware
[20:39:57] <skunkworks> jepler calculated it for me.. It has 3 inputs where the 3rd switches between 1 and 2 inputs. (if that makes sense)

[20:40:32] <Tom_itx> i wish there was a little better explanation of both those functions
[20:41:04] <pcw_home> the lut5 makes sense to me. its just a lookup table
[20:41:19] <Tom_itx> so what would the 202 equate to?
[20:42:10] <pcw_home> 00000000000000000000001000000010
[20:42:46] <Tom_itx> i mean, how do you determine from the number, how many inputs there are and what function the output performs?
[20:42:49] -!- andypugh [andypugh!~andy2@cpc14-basl11-2-0-cust436.20-1.cable.virginm.net] has joined #linuxcnc
[20:43:15] <skunkworks> I think there are always 5 inputs..
[20:43:34] <Tom_itx> says 'up to 5'
[20:43:46] <pcw_home> 0 => 0
[20:43:48] <pcw_home> 1 => 0
[20:43:49] <pcw_home> 2 => 1
[20:43:51] <pcw_home> 3 => 0
[20:43:52] <pcw_home> etc
[20:44:01] <pcw_home> (upto 31)
[20:44:10] <andypugh> lut5?
[20:44:13] <pcw_home> the input is just the bit address
[20:44:32] <Tom_itx> so is the 202 representd there hex?
[20:44:36] <pcw_home> the output just returns the bit at the bit address
[20:44:41] <pcw_home> yes
[20:44:53] <pcw_home> (if entered in hex)
[20:44:58] <Tom_itx> so on the hal line you don't need to write 0x202
[20:45:06] <pcw_home> you do
[20:45:14] <Tom_itx> ok well he didn't so it must be decima
[20:45:14] <Tom_itx> l
[20:45:31] <pcw_home> that would be odd
[20:45:59] <andypugh> No, it's even in any base
[20:46:04] <Tom_itx> setp lut5.0.function 202
[20:46:04] <Tom_itx> setp lut5.1.function 202
[20:46:17] <Tom_itx> from skunkworks' example
[20:46:22] <andypugh> That will be interpreted in decimal.
[20:46:34] <pcw_home> I assumed all hal parsing of constants was the same (decimal if no 0x)
[20:46:53] <andypugh> 11001010
[20:47:11] <Tom_itx> so what would the value for a 3 input AND gate be?
[20:47:49] <pcw_home> connected to which inputs?
[20:47:55] <Tom_itx> i don't care
[20:48:01] <Tom_itx> probably the first 3
[20:48:27] <pcw_home> bit 7 = 1
[20:48:31] <Tom_itx> in0..2
[20:48:38] <pcw_home> all others 0
[20:49:02] <pcw_home> (assuming the unused pins are 0)
[20:49:28] <pcw_home> (you can make the unused pins dont-care by duplicating the pattern)
[20:49:29] <Tom_itx> 64 dec
[20:49:53] <pcw_home> decimal just makes this hard
[20:50:25] <Tom_itx> i still don't get the association of the logic 'and or xor etc' with the table
[20:51:30] <pcw_home> so "or" is 0000 0000 0000 0000 0000 0000 0000 1110
[20:51:55] -!- ekolojik has quit [Quit: Konversation terminated!]
[20:52:40] <pcw_home> you can generate at the ~4 billion logic functions of 5 inputs with the lut5 (this is how the logic in FPGAs works)

[20:54:09] <Tom_itx> i'm not getting it :(
[20:54:16] <skunkworks> don't feel bad...
[20:54:30] <Tom_itx> are you reading the table top to bottom with your string of numbers?
[20:54:57] <pcw_home> No I am looking at bit(n)
[20:55:44] <pcw_home> so an input of 0 returns an output that the bit value of bit 0
[20:55:56] <pcw_home> that is
[20:57:15] <pcw_home> so on your 3 input and gate, only address 111 (bit 7) returns 1
[20:57:20] -!- heathmanc [heathmanc!519a147e@gateway/web/freenode/ip.] has joined #linuxcnc
[20:57:25] <Tom_itx> it might be easier for me to start with 'logic9'
[20:57:32] <heathmanc> got a bitfile/firmware issue with a 4i69 card
[20:57:37] <heathmanc> anybody interested?
[20:57:50] <Tom_itx> heathmanc elaborate
[20:58:12] <andypugh> pcw_home: You take the 4i69 and I will try to explain to Tom :-)
[20:58:30] <Tom_itx> as JT-Shop would say... it's nap time
[20:58:48] <heathmanc> error when loading linuxcnc is board has fpga 6slx25fg, but the firmware in the bit is for fpga 6slxftg256
[20:59:09] <heathmanc> just received the 4i69 today
[20:59:12] <Tom_itx> heathmanc did you compile it?
[20:59:37] <heathmanc> lol, you lost me there, my abilities lie elsewhere. this bit file was provided by pcw last week
[20:59:40] <Tom_itx> andypugh i'll bug ya later about the logic
[20:59:47] <Tom_itx> i gotta get caught up here a bit
[20:59:49] <heathmanc> was supposed to be for a 4i69 and a 7i48
[21:00:00] <andypugh> Tom_itx: Let me try quickly. If you see input 0 as the "1s" bit of a binary number, and input 1 as the "2s" and 3 as the "4s", then the inputs are combined to make a binary number that can have values from 0 to 31.
[21:00:25] <heathmanc> it is the 4i69-25 card
[21:01:04] <pcw_home> how big is the bitfile
[21:01:23] <andypugh> And those values of 0 to 31 are used to pick one bit of a 32-bit number that you setp into the function in HAL.
[21:01:49] <heathmanc> 801563
[21:01:53] <Tom_itx> andypugh, so looking at the chart on the doc page, 0x80 would be a 3 input and?
[21:02:21] <andypugh> So, in the AND3 case, bits 0, 1 and 2 are all set, = 1 + 2 + 4 = 7. So the output value of the function is whatever the value of bit 7 of the parameter is set to.
[21:02:58] <andypugh> Tom_itx: Yes. Because bit 7 is set.
[21:03:06] <pcw_home> so I probably forgot to change the card type when I built the bitfile (thats a X25 bitfile but the IDROM card type tag is wrong)
[21:03:39] <heathmanc> if you say so, this portion is foreign to me
[21:03:42] <Tom_itx> ok can you have a multi input or just the same?
[21:03:48] <Tom_itx> say a 3 input or
[21:04:12] <andypugh> Tom_itx: The calculators in Linux and MacOS let you toggle individual bits in a number and just read out the result ;-)
[21:04:34] <pcw_home> 3 input or is 1111 1110
[21:04:57] <pcw_home> 0xFE
[21:05:25] <andypugh> Though that is also (0 or 1 or 2) xor (3 or 4) (I think :-)
[21:05:54] <pcw_home> 3 input nor is the inverse 0000 0001
[21:07:05] <pcw_home> Whats nice about luts5 is that _any_ function of 5 inputs is possible
[21:07:23] <Tom_itx> if you know how to calculate them :)

[21:11:44] <Tom_itx> pcw_home, you can mix logic with it as well? say 3 input AND with an OR on 4 & 5?
[21:12:02] <pcw_home> Yes
[21:12:08] <andypugh> Tom_itx: Yes, except there is only one output bit.
[21:12:16] <Tom_itx> ok, i'll try to wrap my head around it this evening
[21:12:24] <Tom_itx> andypugh yeah i got that part
[21:12:32] <pcw_home> yes, except for that small detali
[21:13:01] <andypugh> It's great for things like door/pause/start interlocks, that sort of thing. You just need to write out what the output should be for every situation, and calculate the parameter.
[21:13:10] <Tom_itx> so how are logic and lut different? they seem quite similar
[21:13:19] <Tom_itx> other than the 5 input restricton on lut
[21:13:51] <Tom_itx> andypugh that's kinda what i'm looking at
[21:13:52] <andypugh> logic only does and / or / xor. lut5 does any possible input to output mapping
[21:14:17] -!- zumba_addict has quit [Quit: zumba_addict]
[21:14:43] <Tom_itx> the kick to it is that i have a button that will toggle 2 outputs
[21:14:47] <andypugh> And if you find that yout lut5 logic is wrong, you can just alter one number, rather than try to figure out how your chain of 37 and2 and or2 blocks fit together.
[21:15:00] <Tom_itx> but needs certain criteria on one but different on the other
[21:16:02] <pcw_home> LUT5 can do any function, logica is hardwired to and or xor etc
[21:16:35] <Tom_itx> i'll draw a flow chart first to make sure i have the logic part figured out
[21:16:52] <Tom_itx> then see if this is gonna work with lut or logic
[21:17:31] <pcw_home> for example you can make a 3 input mux from lut5 but not from logic
[21:18:34] <andypugh> Tom_itx: To do that, I would use lut5 to calculate the logic, and use a latch to latch the output of the lut5 to the output. Use the lut5 (earlier in the the thread) to calculate the output value, and if there is only one button toggle the latch on that button.
[21:19:31] <andypugh> If you need to recalculate the output on a change in more than one input then you can OR those inputs together into the latch toggle.
[21:19:50] <Tom_itx> i did it with and & or gates in hal and it _almost_ works the way i expect
[21:20:09] <andypugh> Or it might be better to feed the latched input from the button into the lut5. It would depend on what is needed.
[21:20:11] <Tom_itx> there is one hitch i haven't quite figured out

[22:56:30] <Tom_itx> inch or metric
[22:56:33] <Tom_itx> i suppose
[22:56:47] <Tom_itx> or encoder count maybe?
[22:57:04] <someone972> It says (e.g. 0.0625 for 16tpi)
[22:57:12] <someone972> Is that threads per inch?
[22:57:15] <someone972> turns per inch?
[22:57:27] <Tom_itx> threads per inch is tpi
[22:57:43] <Tom_itx> more or less the same
[22:58:06] <someone972> Is there anything other than rigid tapping where it would need to be syncronized?
[22:58:15] <Tom_itx> lathe
[22:58:32] <Tom_itx> depends what you are doing
[22:58:54] <Tom_itx> single point threading
[22:59:18] <CaptHindsight> gear cutting
[22:59:38] <someone972> So I assume that with my diy 3-axis machine with just a dremel that I set the rpm manually, that would never be used then

[23:00:27] <CaptHindsight> since your dremel can't be synced
