#emc | Logs for 2011-11-16

[00:00:12] <andypugh> Is it being detected?
[00:00:23] <PCW> Resolver yes, I need to check the sserial counter thing
[00:00:48] <andypugh> Did you link 1 to 3 and 2 to 4 on the enable plug?
[00:00:58] <PCW> Is the 8I20 jumpered for 5V CAT6 power or field power?
[00:01:09] <PCW> (if you have no green LEDS)
[00:01:34] <emcrules_d510> yes i jumpered the enables as you described. how can i tell if it's beind detected?
[00:01:45] <emcrules_d510> jumpered for feild power
[00:02:05] <PCW> Do you have field power?
[00:02:59] <emcrules_d510> sorry i thought the manual read that it would use the bus power to generate the 5V
[00:03:32] <PCW> you need the green ISO PWR led before anything is going to happen
[00:03:34] <PCW> so if you dont have 24V field power, jumper for 5V cable power

[00:03:48] <PCW> (8-36V field power I think)
[00:04:01] theorb is now known as theorbtwo
[00:04:02] <emcrules_d510> it's alive
[00:06:01] <emcrules_d510> ok HV on = yellow Fault=red Iso PWR = green LV = yellow PWR = green
[00:09:01] <PCW> OK so thats a start (what is you HV?)
[00:09:21] <emcrules_d510> 165VDC
[00:09:42] <emcrules_d510> DC bus from another servo drive
[00:10:00] <PCW> OK that should start if the cable is right (some people have used xover cables)
[00:10:27] <emcrules_d510> What is jumper W3 for?
[00:11:43] <PCW> Unused option on the PIC used for power supply drive
[00:12:33] <andypugh> emcrules_d510: A slow-flashing green is what you want to see

[00:17:10] <andypugh> emcrules_d510: Enable?
[00:17:59] <andypugh> And what are you doing to test it? Command line? What commands?
[00:18:40] <emcrules_d510> andypugh: just trying to launch emc
[00:18:58] <andypugh> From the menu?

[00:19:14] <andypugh> Any messages at all?
[00:19:50] <andypugh> You could try halrun then source <that file I gave you>
[00:20:03] <emcrules_d510> same one 8i20.hal:28: Pin 'hm2_5i23.0.8i20.0.7.angle' does not exist
[00:20:31] <emcrules_d510> im using you config as it stands
[00:20:35] <andypugh> It probably means that that pin does not exist
[00:21:07] <andypugh> It is quite likely that what I sent you wasn't a config, just a HAL file.
[00:21:19] <andypugh> halrun

[00:28:55] <andypugh> emcrules_d510: fresh pull of v2.5?
[00:29:14] <andypugh> Any flickering of green lights on startup?
[00:29:26] -!- robh__ has quit [Ping timeout: 276 seconds]
[00:29:35] <andypugh> I would initially guess that the 7i44 is in the wrong header.
[00:29:47] <emcrules_d510> 2.5 was a fresh pull as of last night
[00:29:57] <andypugh> does dmesg show any smart serial lines?
[00:31:39] <emcrules_d510> dmesg shows all the pins on P4 as IOport
[00:36:16] <andypugh> You could try putting the sserial_port_0=00000000 back in?
[00:40:04] <PCW> Andy the counter stuff does not appear to work (it seems to increment and decrement by ~65536)
[00:41:12] <emcrules_d510> andypugh: how do i kill or unload hm2_pci
[00:41:36] <andypugh> Is it stuck?
[00:41:54] <andypugh> halrun -U might do it
[00:42:24] <andypugh> PCW: how many bits of counter?
[00:43:28] <PCW> Im not sure probably 16
[00:43:45] <andypugh> It worked in testing :-(
[00:44:16] <andypugh> Though I only used 4 and 5 bit counters, incrementing and decrementing by 1
[00:47:32] <PCW> A bi directional 16 bit counter can count 16384 counts between samples without ambiguity (thats that business of lookin and the MSB and NMSB)
[00:48:02] -!- micges has quit [Quit: Ex-Chat]
[00:48:27] <andypugh> I have it wrapping if the delta is more than half a full count.
[00:49:33] <PCW> I dont think that works for bidirectional counters
[00:50:35] <andypugh> Well, there is the problem that I have no idea what data comes in on the register.
[00:50:50] <andypugh> What do you mean by a "bidirectional counter"?
[00:51:25] <PCW> A counter that can count up or down
[00:51:39] <andypugh> My assumption was an N-bit value that either incremented or decremented by "a bit" between reads.
[00:52:27] <andypugh> So, it wraps at +/- max counts, rather than at zero?
[00:52:44] <andypugh> I assumed a wrap at zero, I think.
[00:52:44] <PCW> No by a bit but by may counts
[00:54:21] <PCW> well it does its just a binary number. if its at 0 and counts down one you get 0xFF for example (= -1 in twos compelment)
[00:54:58] <andypugh> If it was 8 bits, what would happen at -128?
[00:55:19] <PCW> Nothing
[00:56:03] <andypugh> Not a wrap to +127?
[00:56:12] <PCW> well it would go from -128 to plus 127
[00:56:31] <PCW> assuminmg you treated it as 2s complement
[00:57:21] <andypugh> OK, I will look at it tomorrow. Perhaps my code broke when I moved it from the test case to the driver.
[00:58:14] <andypugh> But it's a signed number? I think that is where I have been going wrong.
[00:58:30] <emcrules_d510> andypugh:http://pastebin.com/r2CjSY5R
[00:58:37] <andypugh> (I will need to sign-extend it)
[00:59:43] <PCW> If you are going to promote to larger number than first step is to sign extend (at least I think so)
[01:01:52] <andypugh> it needs to be sign-extended to be treated as a signed number.
[01:02:19] <andypugh> Or the arithmetic just breaks
[01:02:46] <andypugh> (and I need to condier up-versioning the Hostmot2 driver)

[01:03:28] <andypugh> emcrules_d510: That doesn't look like the latest emc2.
[01:03:37] <PCW> Well the resolver stuff works, I have yet to test the index logic
[01:04:29] <emcrules_d510> andypugh: it loads up as 2.5.0-pre2 i only installed git on this pc last night and pulled
[01:04:54] <andypugh> You have a fresh pull of 2.5, I assume you have compiled it, but did you . ./emc-environment?
[01:05:12] <emcrules_d510> yes every time i open up terminal
[01:05:38] <emcrules_d510> what about symlink
[01:06:48] <andypugh> You did compile?
[01:07:09] <emcrules_d510> yes
[01:07:11] <andypugh> And you used the emc-environment in /emc2-dev/scripts?
[01:07:28] <andypugh> (Just checking)
[01:07:40] <emcrules_d510> ah shit wrong dir
[01:07:55] <andypugh> That was from memory, let me check...
[01:08:41] <emcrules_d510> oh no from /emc2-dev dir so i should of been ok
[01:09:37] <emcrules_d510> just ran it again and i get the once per shell message
[01:09:55] <andypugh> if you man hostmot2, does it say sserial_port_0=000000 ?
[01:11:24] <emcrules_d510> in the man page?
[01:11:28] -!- crazy_imp has quit [Ping timeout: 240 seconds]
[01:11:28] <andypugh> Yes
[01:12:01] <emcrules_d510> nope
[01:12:38] <andypugh> in the emc2-dev directory, what does git branch say?
[01:13:00] <emcrules_d510> also i do not have a 5i23 dir in emc2-dev only a firmware dir for the 7i43
[01:13:19] <andypugh> Ignore that
[01:13:24] <emcrules_d510> master
[01:13:44] -!- crazy_imp [crazy_imp!~mj@a89-183-25-110.net-htp.de] has joined #emc
[01:14:20] <andypugh> I am puzzled, master has supported 8i20 for a long time
[01:14:53] <andypugh> But then, that wouldn't say 2.5_pre
[01:15:03] <andypugh> (I don't think)
[01:15:27] <andypugh> master is 2.6
[01:16:37] <andypugh> It might have been easier to get the precompiled binary from the buildbot, you know.
[01:18:04] <emcrules_d510> sorry i don't instructions on the wikki?
[01:18:52] <andypugh> Anyway, if you use whatever syntax the man page says, you should be able to get the 8i20 to wake up. Perhaps num_sserials=8 ?
[01:19:43] <andypugh> With the previous syntax, the sserial cards were disabled by default.
[01:21:27] <andypugh> buildbot is section 1.4 here: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2
[01:22:32] <andypugh> But then you are likely to end up with more confusing system
[01:22:42] <emcrules_d510> thanks andy
[01:23:38] <andypugh> If you do what the man page says (regardless of version) it ought to work.
[01:23:53] <andypugh> But I need to log off now.

[04:59:30] <mrsun> yeah, have to fix the micromill so ic an make parts for the bigger wood mill :P
[04:59:37] <mrsun> so i guess the egg has to come first
[05:06:43] <danimal_laptop> eventually you can make a huge mill
[05:07:11] <danimal_laptop> but you'll have to make 40 progressively bigger mills in the process
[05:07:30] <danimal_laptop> evolution of mill
[05:09:58] <mrsun> =)
[05:10:48] <mrsun> the one for wood is actualy for the things im gonna take over after my father, alot of very repetetive steps in making it so it needs some automasation while at the same time keeping the hand work....
[05:11:14] <mrsun> sucks that stuff has to be so repetetive all the time :P

[15:46:47] <psha> FinboySlick: if you want atom - take a look at d510mo
[15:47:40] <A2Sheds> FinboySlick: dunno, never used it, I don't care for Intel's EFI agenda, lack of BIOS docs and antitrust violations. D510 is what lots of devs here have used successfully.
[15:48:39] <FinboySlick> A2Sheds: Oh, didn't notice EFI, I saw 945GS and figured it'd be okay.
[15:49:02] <A2Sheds> I didn't notice if that board has EFI or not
[15:49:46] <FinboySlick> psha: It's what I've been looking for, but 510 are very hard to find. I find more N270 which seems similar but with less cache and slower FSB.
[15:53:27] <A2Sheds> interesting .hal has: loadrt hal_paraport cfg="0x0278 out" , yet my BIOS has EPP set to 378 and it works
[15:53:35] <JT-Shop> seems the 510 has been replaced with the D525BOX motherboard and has the parallel port brought out
[15:54:10] <FinboySlick> JT-Shop: If they changed the chipset, all bets are off though.
[15:54:39] <psha> FinboySlick: you may try single core (410) or later revision chip (425/525)
[15:54:42] <A2Sheds> I'm trying pncconf and it doesn't let me change the setting for EPP to 378
[15:54:51] <psha> but *25 boards are a bit worse
[15:54:55] <FinboySlick> psha: I have a 425 here (and a 525)

[16:07:26] <pcw_home> AFAICR the 525 BIOS is totally broken as far as setting PP modes goes...
[16:07:37] <pcw_home> (and reporting them)
[16:09:25] <pcw_home> reminds me of some early Taiwanese BIOs code comments:
[16:09:26] <pcw_home> "This here for some reason"
[16:11:46] <JT-Shop> we have something like that in the manuals too "Put text here"

[16:15:45] <A2Sheds> and yet they won't share BIOS docs without a Orange cover NDA that takes 2-8 months to process
[16:16:24] <A2Sheds> if you can get you Intel support people to figure out how to apply for it
[16:18:30] <A2Sheds> most of the time the BIOS is just rolled out using a graphical tool with check boxes for hardware used and how it's wired and the modules you want to include, they rarely touch BIOS source

[16:19:37] <A2Sheds> that would explain the broken PP modes unless intel actually has a broken ip block in that chipset
[16:20:04] <A2Sheds> but they usually cover that up with a BIOS workaround
[16:23:07] <danimal_laptop> i better run to frys and grab a d510 before they're gone
[16:26:25] <pcw_home> I think its and external PP chip just a broken BIOS
[16:26:46] <psha> FinboySlick: *25 are bad for you?
[16:27:04] <A2Sheds> ah, which superIO do they use?
[16:27:32] <FinboySlick> psha: This one looks okay, the only problem I have with it is that it's not mine :P
[16:27:35] <danimal_laptop> hi JT-Shop
[16:27:56] <psha> pcw_home: while you are here... are 7i70 and 7i76 supported in 2.5?
[16:28:00] <psha> andy was working on them?
[16:28:28] <FinboySlick> psha: Since I'm going to buy one, I'd kind of like an upgrade in terms of performance.
[16:28:54] <psha> FinboySlick: *25 is better then *10 which are better then N270 :)
[16:29:14] <FinboySlick> psha: By performance I mean jitter.
[16:30:07] <A2Sheds> d510mo uses a Winbond W83627TGH-I super IO for PP
[16:31:08] kanzure_ is now known as kanzure
[16:31:47] <FinboySlick> I'm very likely to get a mesa card for io anyway. The little 34 port half-height would be great.
[16:31:52] <A2Sheds> Winbond W83627TGH-I super IO tests fine with coreboot so it must be a crappy BIOS of they did something wrong with the PCB, hard to imagine though
[16:32:05] <A2Sheds> of/or
[16:32:43] <JT-Shop> Hi Dan
[16:33:14] <JT-Shop> psha: I have the 5i25 7i76 combo running on 2.5
[16:33:47] <psha> JT-Shop: thx
[16:33:49] <danimal_laptop> got the shop all cleaned and ready for the new mill
[16:34:18] <JT-Shop> cool, mine is still a mess
[16:34:50] <danimal_laptop> so is mine, but it's clean for my standards
[16:35:04] <A2Sheds> psha: is that the order based on least latency jitter? *25 -Best , *10, N270 -worst
[16:35:23] <psha> A2Sheds: no, 25 jitter is worse then 10
[16:36:03] <FinboySlick> Is 270 better than 25?
[16:36:28] <A2Sheds> ok, BEST- *10, *25, N270 - WORST
[16:36:43] <FinboySlick> Heh, okay.
[16:37:50] <danimal_laptop> http://www.frys.com/product/6147609?site=sr:SEARCH:MAIN_RSLT_PG
[16:38:00] <danimal_laptop> they usually have them in stock at my local store
[16:38:15] <psha> A2Sheds: probably, but i'm not confident in *25 vs 270
[16:38:39] <danimal_laptop> if someone in the states wants, i can grab one for them
[16:38:45] <JT-Shop> in laymans terms what is the problem with the 525?
[16:39:45] <FinboySlick> And along with JT-Shop, is the problem really the CPU or more its interaction with the chipset?
[16:41:45] <pcw_home> psha: yes 7I70 and 7I76 are supported in 2.5 now
[16:44:19] <pcw_home> JT-Shop: I dont think there is an actual problem now but for EPP devices (Pluto, 7I43, Pico)
[16:44:21] <pcw_home> the BIOS neither sets the mode correctly or reports them correctly (this was fixed by a work-around, I think in 2.4.6)
[16:48:46] <A2Sheds> heh, my Core 2 Duo + i945 board uses the same winbond superIO
[16:49:03] <A2Sheds> that explains the PP strangeness
[16:50:29] <A2Sheds> the thing is we can tell Intel how to fix it but they won't
[16:50:49] <JT-Shop> pcw_home: thanks, I remember now that you reminded me :/
[16:56:22] <psha> pcw_home: thanks, guys on russian forum were wondering
[16:58:51] <A2Sheds> if anyone has or has a chance to test latency on any of the AMD APU (Fusion) boards it would be handy
[16:59:41] <A2Sheds> http://www.newegg.com/Product/Product.aspx?Item=N82E16813157273 or similar
[16:59:48] <pcw_home> The good thing is that Andys driver supports all the new (and future) SSERIAL cards now
[17:00:39] <A2Sheds> the we can replace the BIOS with coreboot and have full control over the chipset registers
[17:01:35] <pcw_home> But it has no real-time I/O (well Ethernet)
[17:02:52] <psha> A2Sheds: i've tested amd phenom with 880(?) chipset and it was nice
[17:03:01] <psha> so my bet is that fusion apus are good too
[17:03:31] <psha> however there would problem with video drivers

[19:43:39] <mrwhiteman> it has 130000 ppr in the encoders
[19:45:32] <mrwhiteman> i see in the datasheet that it has: pulsetrain,analog,dio,rs422
[19:46:06] <mrwhiteman> but don't know how the analog options works
[19:47:07] <mrwhiteman> which of these funcions is supported in emc2 out of the box?

[19:50:58] <mrwhiteman> my idea was to control the machine with a pci-fpga board like mesa, but i have just seen that the vfd's were included, so i don't know if i can use them

[19:57:07] <JT-Shop> mrwhiteman: yea
[19:57:18] <JT-Shop> Dan cool!
[19:57:24] <JT-Shop> can you tell the difference?
[19:58:09] <danimal_laptop> JT-Shop: not sure yet, i'm going to try milling something in a second so i can hear
[19:58:55] <mrwhiteman> andypugh: is the fpga/pci option better than control with other options(like rs422) commercial vfd's for the brushless motors?

[20:00:01] <danimal_laptop> JT-Shop: i got the drywall and insulation for the last wall in the shop. i wanted to do it before the mill comes this week
[20:00:06] <JT-Shop> yuk a smart drive
[20:00:29] <danimal_laptop> i went with 5/8" drywall, not sure if it'll help with the sound or not
[20:00:55] <JT-Shop> yep it will be denser than the 1/2" and ring less
[20:01:17] <danimal_laptop> now i get to take down a bunch of shelving and conduit and air piping to put the drywall up :(
[20:01:28] <andypugh> mrwhiteman: Don't mistake me for an expert. But you will probably find that the FPGA + dumb drive combinaiton is cheaper, and gives you more control.
[20:01:33] <danimal_laptop> cool, it was almost the same price so i figured why not

[20:15:36] <bjam68> Hi All, Can someone help me to set the correct step time/step space values for SMC44-D stepper drivers? The driver is based on lm18245T chip.
[20:17:41] <andypugh> bjam68: Try 5000 for step length, that's normally enough. Stepconf generally sets space length to zero and uses "Reset" so it doesn't matter
[20:17:55] -!- JT-5i25 [JT-5i25!~chatzilla@216-41-156-59.semo.net] has joined #emc
[20:19:13] <bjam68> andypugh: thanks, so I assume there is no big mistake when I leave the default values proposed for the "Other" driver in Stepconf..?
[20:19:46] <andypugh> No, it will probably just work.
[20:19:59] <JT-Shop> jdhNC: got that right :)\
[20:21:27] <bjam68> andypugh: Next question would be: what is the special case when it's necessary to change these default values?
[20:22:17] <andypugh> When you want very fast pulses, and your motors can handle it, or if you have especially slow drives, maybe?
[20:24:20] <bjam68> andypugh: OK , so it's generally could be a good idea to play a bit with this for the better performance, but normally should work out of box..
[20:24:47] -!- psha has quit [Quit: leaving]
[20:25:33] <andypugh> Well, if you can use shorter pulses, and you are using Reset, and you have a short base-thread execution period, then a shorter pulse length can give the CPU more time for other tasks.
[20:25:47] <andypugh> But that is a bit if a corner-case
[20:29:26] <bjam68> andypugh: what do you mean by "using Reset"?

[22:06:39] <emcrules_d510> andypugh: any more doc updates on bldc?

[22:08:45] <emcrules_d510> basically use bldc to send current and phase angle to drive.
[22:09:02] <andypugh> Yes, in whatever format you need.
[22:10:45] <emcrules_d510> what are the init pins for?
[22:13:34] -!- FinboySlick has quit [Quit: Leaving.]
[22:19:00] <andypugh> Homing, if you don't have any absolute reference
[22:19:53] <andypugh> Depending on the mode, it will either stepper the motor to index, or home it magnetically.
[22:20:18] <andypugh> But having Hall sensors is best. (or a resolver, or fanuc sensors)
[22:21:00] <emcrules_d510> how do you tie the halls to bldc?
[22:21:09] <andypugh> In HAL?
[22:21:19] <emcrules_d510> i dont see input pins for that
[22:21:33] <andypugh> What config string?
[22:21:55] <emcrules_d510> for the bldc?
[22:21:58] <andypugh> you only see Hall pins with a "h"
[22:22:29] <andypugh> It's a rather polymorphic component
[22:22:56] <andypugh> What's your hardware?
[22:22:59] <emcrules_d510> i dont see any pin on the bldc component that woul lead me to connect my hall signal to in hal
[22:23:26] <andypugh> Where do you not see the pins?
[22:23:43] <emcrules_d510> so you call it with certian parms on loadup and i would get the pins i need
[22:23:49] <emcrules_d510> hal config
[22:24:19] <andypugh> Unless you had a "h" in the bldc string, you won't see the Hall pins
[22:24:44] <andypugh> What hardware do you have?
[22:24:50] <emcrules_d510> ah i see it now!! what are all the config options?
[22:25:09] <andypugh> man bldc
[22:25:28] <emcrules_d510> terminal told me ther was no man page
[22:26:00] <andypugh> Worked for me..

[22:46:53] <Danimal_garage> sweet!
[22:47:04] <Danimal_garage> what is it?
[22:47:17] <syyl> the mounting bracket for the spindle encoder on my mill
[22:47:32] <syyl> a bit over-engineered ;)
[22:48:01] <Danimal_garage> very nice
[22:48:10] <Danimal_garage> no such thing
[22:48:21] <Danimal_garage> we'll call it well engineered
[22:49:10] <syyl> ;)
[22:50:08] <A2Sheds> are you going to anodize the wood grain into it to fool people?

[23:00:57] <andypugh> You need to paint it red too :-)
[23:01:34] <andypugh> And why not cast-iron rather than aluminium?
[23:02:26] <andypugh> Actually, thinking about it, for a spindle encoder, you could just use the wood :-)
[23:02:37] <Danimal_garage> what;s the melting point for iron vs aluminum?
[23:02:52] <Danimal_garage> guess i could look that up...
[23:02:54] <andypugh> Aluminium is about 600, iron 1500
[23:02:59] <Danimal_garage> c?
[23:03:02] <andypugh> (That's C)
[23:03:11] <Danimal_garage> sweet, i can use my kiln
[23:03:36] <andypugh> You need a bit of superheat for casting.
[23:03:40] <Danimal_garage> i'll make some servo mounts :)
[23:03:49] <Danimal_garage> superheat?
[23:06:20] <andypugh> Heat above the melting point
[23:07:01] <andypugh> http://www.gizmology.net/stovetop.htm suggests cent coins as a handy and cheap source of zinc...
[23:07:26] <Danimal_garage> how much above?
[23:07:47] <Danimal_garage> my kiln will probably hit 1600c
[23:09:47] -!- mrwhiteman has quit [Quit: byez]
[23:10:08] <andypugh> That's enough for bronze
[23:10:19] <andypugh> Might even get you iron.
[23:10:39] <andypugh> You want 100C extra, not loads.
[23:10:52] <Danimal_garage> sweet
[23:11:08] <andypugh> mrwhiteman was talking about using a microwave earlier: http://www.cientificosaficionados.com/fundicion%20microondas/fundicion%20microondas.html
[23:12:25] <andypugh> Checking, 1500 is about the pouring point for cast iron, it melts at 1200, so you should be able to do iron castings too.
[23:13:52] <Danimal_garage> sweet
[23:14:00] <Danimal_garage> i got a bunch of iron
[23:15:57] <Danimal_garage> not sure what to melt it in though lol
[23:22:02] <syyl> andypugh, because my friend cant melt CI ;)
[23:22:11] <syyl> only aluminum so far
[23:22:41] <syyl> and models for aluminum are painted green
[23:22:42] <syyl> :D

[23:28:06] <syyl> real men cast in shorts ;)
[23:28:39] <Tom_itx> do you wax the wood before you stick it in the sand?
[23:28:58] <syyl> nope
[23:29:03] <syyl> we use powder

[23:29:52] <andypugh> Danimal_garage: You might want to do some research on crucible to material compatibility. The chemistry gets interesting.
