12:37 AM fragalot: hi
12:40 AM BitEvil is now known as SpeedEvil
12:56 AM CaptHindsight: been quiet for hours
12:57 AM fragalot: that's what happens at night
12:57 AM CaptHindsight: found an odd Asrock mother board that has poor jitter on the servo thread
12:58 AM Deejay: moin
12:59 AM CaptHindsight: the channel has been mostly Euro and US centric for years
01:00 AM CaptHindsight: a few in Australia and every now and then somebody in Asia
01:04 AM fragalot: https://www.youtube.com/watch?time_continue=3&v=ozZ6HzumC_o
01:04 AM fragalot: art.
01:06 AM IchGucksLive: morning
01:10 AM IchGucksLive: getting a nice day in germany im off 2 garden
03:44 AM Loetmichel: hmmpfff... soldering aluminium, first try: failed... i need an oxyacetylene set (not a bunsen burner), better solder and better flux... -> http://www.cyrom.org/palbum/main.php?g2_itemId=17058&g2_imageViewsIndex=1
03:46 AM miss0r: so you basically need everything from the start? :D
03:46 AM miss0r: Might I ask why you are not using TiG ?
03:47 AM Loetmichel: miss0r: because that would be to easy. boss said he didnt want to buy a tig set
03:48 AM miss0r: hehe. alright. But what will it set him back versus oxyacetelene & solder PLUS someone having to learn to solder alu properly (not an easy task) versus just getting a tig, which is stupidly easy to use
03:50 AM Loetmichel: i may have a chance... his wife (the "CFO") is in the hospital... so he may be open to some arguments.
03:50 AM Loetmichel: have to hurry though
03:50 AM Loetmichel: from that POV its not that bad that that solder test failed
03:51 AM miss0r: indeed :]
03:51 AM miss0r: plus, you can do stainless & steel with the tig as well ;)
03:52 AM Loetmichel: last time i welded with a tig was nearly three decades ago though... i might need a bit of "getting used to" again ;)
03:53 AM miss0r: nah.. its like riding a bike ;)
03:54 AM Loetmichel: may i add that i am an EE by trade, not an ME?
03:55 AM miss0r: You may.
03:55 AM miss0r: But that doesn't change the facts :D
03:57 AM gloops: what are these cheapo tig sets like, anyone tried one?
03:57 AM miss0r: Thats a pretty general question :D
03:57 AM gloops: i mean the lowest priced simply set
03:58 AM gloops: simple
03:58 AM miss0r: I have no idea. I've always used Migatronic
03:58 AM miss0r: but i think 'this old tony' has a video about something like that
03:58 AM gloops: https://www.machinemart.co.uk/p/clarke-at133-arc-tigmma-inverter-welder/
04:00 AM gloops: i wouldnt mind a tig sat around, i dont want to buy used though and wouldnt spend a lot for the odd time id use one
04:00 AM miss0r: I use a migatronic pilot 2400, you can get that as a used model for ~1500EUR
04:00 AM gloops: i wouldnt spend that much it would only be for little things of my own, not to sell anything
04:01 AM miss0r: gloops: remember, you need to use AC to weld aluminium
04:02 AM gloops: run from gennie?
04:02 AM miss0r: wha?
04:03 AM gloops: generator
04:03 AM miss0r: you can run any welder off a generator. As long as the generator can supply the current /phases needed
04:04 AM miss0r: I'm talking about the output current from the tig. When welding aluminum you should use alternating current. With iron, steel/stainless you can use direct current
04:05 AM enleth: and it's not the utility AC fed into tge torch, an AC TIG is a square waveform generator with an absurdly high current output amplifier
04:06 AM miss0r: indeed
04:08 AM gloops: none of those cheapo ones has ac
04:09 AM enleth: pretty much, yes
04:09 AM enleth: it requires a completely different power section design
04:11 AM gloops: i have got some decent gas welding gear but not had bottles for years, becoming a bit unaccepetable to have gas bottles on domestic property
04:15 AM Loetmichel: gloops: who cares?
04:16 AM Loetmichel: or should i say: who even knows that you have oxy/acetylene bottles on the premises?
04:17 AM gloops: nah dont want complaints and falling out, supposed to be in a metal cage locked etc, plus if neighbours are worried about one thing theyll start watching everything else more closely, easier not to have them at all
04:17 AM Loetmichel: you can use a DC tic welder for alu though with reversed polarity. it eats tungsten rofs like crazy, but it DOES work
04:17 AM Loetmichel: tig
04:36 AM enleth: Loetmichel: most cheap TIGs have the torch connection hardwired to +
04:37 AM enleth: while using a stick welder tig set means you have to scratch start *while* on negative DC
04:40 AM enleth: and AFAIR constant negative tends to embed tungsten into the weld making it kinda shitty for strength
04:41 AM miss0r: In other words: Theres not alot of nice things to sy about that aproach
04:43 AM jthornton: morning
04:44 AM miss0r: mornin
05:31 AM gloops: the air is wet, and has been all week
05:32 AM pink_vampire: hi
05:33 AM gloops: hello
05:34 AM pink_vampire: I need to find a name
05:34 AM pink_vampire: do you know someone in austria?
05:36 AM gloops: cant think of anyone in austria i know off hand
05:36 AM gloops: loetmichel is nearer
05:38 AM pink_vampire: I need to find an austrian name for a girl
05:38 AM gloops: freda
05:39 AM pink_vampire: mmm no
05:40 AM pink_vampire: I need to name her after some important woman in austria
05:40 AM SpeedEvil: Eva
05:40 AM SpeedEvil: https://en.wikipedia.org/wiki/Women_in_Austria
05:41 AM gloops: Eva?
05:41 AM gloops: Elvira
05:41 AM SpeedEvil: You could probably start with the year of birth you're interested in, and then go to birth statistics for average names
05:42 AM gloops: welma, or is it wilma
05:42 AM pink_vampire: she need to be with very nice hands
05:44 AM pink_vampire: Elvira is interesting
05:44 AM gloops: from fairies isnt it?
05:44 AM gloops: Elv
05:45 AM gloops: no..means 'white, fair'
05:46 AM pink_vampire: elv..
05:46 AM pink_vampire: mmm meh
06:16 AM miss0r: o.0 what am i reading?
06:17 AM SpeedEvil: Good question.
06:17 AM SpeedEvil: I'mguessing that pink_vampire has found a time machine.
06:22 AM miss0r: I've seen a few videos of some glue you can apply in a thick layer, and just spray with something for an instant set.. Do you guys know what this stuff?
06:24 AM SpeedEvil: Do photons count as activator?
06:24 AM SpeedEvil: - UV set
06:25 AM miss0r: in this case I would like to be able to put on a pretty big blob of glue and harden it instantly. I need to ajust the focus on a laser, and lock it in place
06:26 AM jdh: loctite 352
06:26 AM pink_vampire: SpeedEvil: I just want to name her after an austrian hand model
06:26 AM SpeedEvil: miss0r: https://www.aliexpress.com/item/Useful-5-Second-UV-Light-Fix-Liquid-Pen-Glass-Welding-Compound-Glue-Repairs-Tool/32761423877.html is awesome
06:27 AM miss0r: Sorry, this item is no longer available!
06:27 AM SpeedEvil: Tehre are eleven billion vendors
06:27 AM SpeedEvil: search 5 second ub
06:27 AM SpeedEvil: v
06:28 AM miss0r: The issues with UV glue is that is will deterioate over time if submitted to sunlight
06:28 AM SpeedEvil: What?
06:28 AM gloops: an austrian hand model could be called anything
06:28 AM SpeedEvil: miss0r: that's not how it works.
06:28 AM miss0r: SpeedEvil: I've never come across a UV hardened glue that does not wither in sunlight
06:28 AM SpeedEvil: It's a photoset polymer, it doesn't then un-UV set if exposed to UV
06:29 AM SpeedEvil: then apply a dab of UV stable epoxy once you've got it tacked into place.
06:29 AM miss0r: I'm not saying its the reversal of _that_ process in particular. it just loses strength in the sunlight
06:29 AM SpeedEvil: So paint.
06:29 AM miss0r: That is an option, indeed. I think I'll get myself one of those UV glue light pens..
06:30 AM SpeedEvil: It's great for what it's great for.
06:30 AM SpeedEvil: It obviously can't work at all for much glue-stuff, where you'd like to glue inside something opaque
06:30 AM SpeedEvil: But for surface fixes, or tacking of transparent stuff, it's awesome
06:31 AM miss0r: sure. But I'm going to apply a drop of glue completely accessable to light, and just harden it.
06:31 AM miss0r: I don't want this laser to move on me.. :) It is 'drawing' a line, that is supposed to be parallel to the saw blade on this ID saw
06:32 AM miss0r: as a point of refrence
06:55 AM pink_vampire: https://www.ebay.com/itm/On-Sale-6-x-6-Fine-Pole-Magnetic-Chuck/271987826835?_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D44040%26meid%3Dc4b3817ccf91488ab6ce84d47bfd9aa6%26pid%3D100005%26rk%3D5%26rkt%3D12%26mehot%3Dpp%26sd%3D323170552184%26itm%3D271987826835&_trksid=p2047675.c100005.m1851
06:56 AM pink_vampire: how is that?
07:02 AM jthornton: you can usually delete all the crap after the ? in a link like that
07:03 AM pink_vampire: https://www.ebay.com/itm/On-Sale-6-x-6-Fine-Pole-Magnetic-Chuck/271987826835
07:03 AM pink_vampire: yes, you right!
07:03 AM jthornton: yup
07:04 AM gregcnc_: you can even delete the text https://www.ebay.com/itm/271987826835
07:04 AM pink_vampire: i just copy and paste :)
07:05 AM SpeedEvil: http://ebay.com/i/271987826835 even
07:06 AM SpeedEvil: .ca even
07:06 AM pink_vampire: omg
07:07 AM gregcnc_: which shade of pink is the lathe going to be painted?
07:08 AM pink_vampire: not going to be painted
07:08 AM pink_vampire: I as able to clean and preserve the original paint
07:25 AM Beachbumpete1: hehe pink lathes
07:29 AM pink_vampire: Beachbumpete1: one day....
07:30 AM gregcnc_: http://www.bluetechlathe.com/image/big/blue_1.jpg
07:31 AM pink_vampire: SOOO CUTE!!!!!!!!!
07:41 AM Beachbumpete1: that is positively vomit inducing ;)
07:48 AM pink_vampire: i just notice that the domain is "blue..."
07:53 AM Beachbumpete1: IKR
07:56 AM CaptHindsight: Hello Kitty lathe, the untapped market
07:56 AM pink_vampire: Hello Kitty lathe OMG!!!!!!
07:57 AM gregcnc_: might bring millennial machinists
07:57 AM gregcnc_: buddy in detroit says everyone is having a hard time hiring for factory work
08:00 AM Beachbumpete1: have any of you guys done a retrofit using kollmorgan servo amps?
08:00 AM CaptHindsight: miss0r: how much adhesive do you need? photopolymers can be set so fast that they can boil or explode ...
08:01 AM Beachbumpete1: there's still factories in Detroit? Go figure
08:02 AM gregcnc_: have a visit plenty of them
08:02 AM CaptHindsight: you just need a type that cures under a higher amount of energy than what will trigger the leftover initiator over time
08:03 AM CaptHindsight: a UV block or/ colorant does the trick
08:03 AM CaptHindsight: or just coat it afterword with something opaque
08:04 AM CaptHindsight: gregcnc_: what are they offering for pay?
08:06 AM CaptHindsight: that the main reason that they can't find people, too little offered
08:08 AM miss0r: CaptHindsight: I just need something a luttle stiffer than heatglue basically, nothing fancy. But i want to be able to cure it near instantly with a spray7UV lamp
08:08 AM CaptHindsight: how thick is the layer?
08:08 AM * miss0r in in the works of facing off a slap of cast iron
08:09 AM miss0r: I need a blob the size of a water drop
08:09 AM CaptHindsight: is it exposed to sunlight after for many decades?
08:09 AM miss0r: no
08:09 AM miss0r: :]
08:10 AM pink_vampire: do i need to put paper between the headstock to the bed?
08:10 AM CaptHindsight: we typically use LED's for curing
08:10 AM miss0r: pink_vampire: What are you doing ?
08:11 AM miss0r: CaptHindsight: That will be fine, sure
08:12 AM pink_vampire: originally was a oil impregnated sheet of paper under the headstock
08:12 AM CaptHindsight: miss0r: have a pic of the application?
08:12 AM pink_vampire: miss0r: I'm rebuilding a lathe
08:13 AM miss0r: CaptHindsight: No. The application is still imaginary :D but basically I want to put a droplet on the outside of a rotating lense on a laser. to make sure it does not move out of focus.
08:14 AM miss0r: imaginery; I have not made the bracket for the laser to sit in yet
08:15 AM CaptHindsight: ~$100/Kg 1Kg = ~ 1L
08:16 AM miss0r: sounds good, as I only need around one droplet of water ~ 0.05ml
08:16 AM miss0r: equal amount, to that of a water droplet
08:16 AM miss0r: I need to pick up the kid. see you later
08:17 AM CaptHindsight: 100W 405nm LED's are <$100ea
08:29 AM gloops: pink vampire does it say 'remove protective paper before assembly' on it?
08:34 AM pink_vampire: no
08:34 AM pink_vampire: it was there when i took it apart
08:35 AM pink_vampire: i think it for preventing the metal from getting cold welded
08:37 AM gloops: well, it has some thickness, is the tailstock adjustable?
08:37 AM pink_vampire: on the headstock
08:38 AM gloops: yes but lowering the headstock will affect things
08:38 AM gloops: oh, adjustment on the headstock...
08:38 AM pink_vampire: I'm going to make one from baking sheets
08:39 AM pink_vampire: the original one is become dust
08:39 AM gregcnc_: you want the center height of spindle and tailstock to be the same
08:40 AM pink_vampire: i know
08:40 AM pink_vampire: but it is not a shim
08:40 AM pink_vampire: it's a paper with oil
08:40 AM gregcnc_: but it was between the bed and headstock
08:41 AM pink_vampire: yes
08:44 AM gloops: i dont think it will hurt to make a new one, i dont know how accurate you need to be but might pay to be careful not to crease or fold it anywhere
08:45 AM gloops: should be height adjustment under the tailstock quill anyway to bring that right
08:45 AM pink_vampire: i cut a new sheet out of a baking sheet
08:46 AM gloops: you can always remove it if there is any problem
08:49 AM pink_vampire: i took pic
08:50 AM gloops: what model emco is the lathe?
08:50 AM gregcnc_: the paper was shim
08:51 AM gloops: yes
08:51 AM gloops: im thinking that too
08:51 AM gregcnc_: I had paper shims in my Emco Compact 6 CNC
08:51 AM gregcnc_: cold weld, lol
08:51 AM gloops: no adjustment on emco tailstock, headstock has been brought up
08:53 AM pink_vampire: gregcnc_: so to use the original or baking sheet?
08:54 AM gloops: you know, i think its better not to dismantle a machine if you can help it, not for cleaning anyway, doesnt serve any purpose cleaning under the headstock
08:54 AM gregcnc_: better get Emco certified news print that I had under mine
08:54 AM pink_vampire: LOL
08:57 AM pink_vampire: https://i.imgur.com/DyV2jls.jpg
08:57 AM pink_vampire: https://i.imgur.com/a9WGjdn.jpg
08:58 AM pink_vampire: https://i.imgur.com/xiNEPDg.jpg
08:59 AM gregcnc_: http://www.practicalmachinist.com/vb/general-archive/lathe-alignment-again-83805/
09:01 AM gloops: well, whatever difference in the thickness of paper, thats how much your cylinders will be tapered, assuming it was right before
09:02 AM gregcnc_: she'll have to do a full alignment because it was off
09:05 AM gloops: all good learning
09:06 AM pink_vampire: i'm not really worry about the tail stock, i'm working mostly on stuff that are anyway too short to even use it
09:06 AM gregcnc_: one day you'll need it, and you'll want it to be be correct
09:07 AM gloops: you want it anyway to steady even short pieces where possible
09:08 AM gloops: guessing the chuck is lightweight, they dont hold like industrial chucks
09:11 AM pink_vampire: the old one is 0.09mm to 0.12mm (full or rust) the baking sheet is 0.07, so + oil it will be 0.08~ or so
11:04 AM gloops: snatch an hour messing with the router, satisified there is very little backlash, nothing visible at all on cuts anyway
11:05 AM gloops: now the weight of the gantry comes into play, very clean cut so far, no vibes no movement
11:21 AM Loetmichel: re at home. juuuust in time. my car has a lock so the roof only folds up when in standstill. just when i reached my driveway the first drops of rain started falling... ;)
11:22 AM holzjunkie: you had a lot of luck
11:22 AM holzjunkie: hy michel
11:37 AM CorK_: Hi there, I just found how to avoid that "TypeError: coercing to Unicode: need string or buffer, NoneType found" killing all Errormessages from halcompile:
11:37 AM CorK_: add "if outfile != None:" between "try:" and "os.unlink(outfile)" in halcompile: line 1410
11:37 AM CorK_: regards Cornelia
11:49 AM fragalot: r== b y hi
11:49 AM fragalot: hi*
12:00 PM Joe_Hildreth: Have a newbie question. RTAI is a mini-kernel on top of the regular Kernel as I think I understand it. Making this a two layer realtime system. The preempt-rt patch create a single realtime kernel. ...
12:02 PM Joe_Hildreth: I get the impression that using RTAI that there is a separate RT API that has to be used, and preempt-rt one can use the standard libraries. My question is, since it appears LCNC supports both RT environments does that mean that there is two code bases or is the RTAI API used for both?
12:02 PM Joe_Hildreth: I am a newbie and just trying to get the stuff sorted out in my head. A five mile fly over answer will be fine.
12:04 PM JT-Shop: the RTAI kernel works better with software step generation and preempt rt works with ethernet Mesa cards as well as PCI and PCIe cards
12:04 PM JT-Shop: RTAI replaces the stock kernel same for preempt rt
12:11 PM Joe_Hildreth: JT, I am compiling preempt-rt on an Ubuntu 16 machine. I am only experimenting but am curious if LCNC can be used on something other than Wheezy. Not that I have an issue with it, but thought it would be interesting.
12:12 PM Joe_Hildreth: I am using Ubuntu 16 because that is what the forum thread was using. I have never done this before so thought I would follow it to get a benchmark.
12:13 PM Joe_Hildreth: I was wondering about the viability of other boards, Beaglebone, Raspberry PI (et. al.) I know folks have got LCNC to work on these but thought it would be an interesting exercise.
12:13 PM Joe_Hildreth: Question, would a software stepper system not run acceptable on a preempt-rt kernel?
12:14 PM Joe_Hildreth: Or does it boil down to hardware?
12:15 PM Joe_Hildreth: I am told the problem with these is that there are issues compiling for the ARM procs.
12:23 PM Rab: Joe_Hildreth, I believe there is time-sensitive code written in x86 ASM which would need to be ported. (My understanding might be out of date.)
12:25 PM JT-Shop: http://buildbot.linuxcnc.org/dists/
12:26 PM JT-Shop: I think there is an ARM one somewhere but can't locate it, any debian based OS is fine
12:26 PM JT-Shop: RTAI on a low latency PC can generate step pulses faster than preempt
12:27 PM Tom_L: https://emergent.unpythonic.net/01474128483
12:28 PM JT-Shop: ah yea
12:28 PM * JT-Shop heads to town
12:30 PM gloops: silkie only ended up with 2 chicks, one disappeared before i found she had any, 1 died hatching, shes got one black one and one white one lol
12:35 PM pcw_home: Joe_Hildreth in general RTAI has lower latency than Preempt-RT but not always
12:37 PM pcw_home: some (typically fast) hardware has great latency with Preempt-RT:
12:37 PM pcw_home: http://freeby.mesanet.com/h97-g3258-preemt-rt.png
12:37 PM Joe_Hildreth: Thank you John and pcw_home. So if one wanted to experiment and use a different version of Linux, then a RTAI kernel should be compiled and installed?
12:38 PM gloops: i tried with mint just following instructions, but ended up messed up
12:39 PM Joe_Hildreth: So I have the kernel compiled and booted to it. Getting ready to git LCNC and compile. But I guess if you have newer hardware perhaps it is a mute point whether you use RTAI or preempt_rt?
12:40 PM pcw_home: You can but building a working RTAI kernel is a lot more trouble than building a working Preempt-RT kernel
12:40 PM Joe_Hildreth: I am sorry for all the questions. I am just trying to wrap my head around this stuff.
12:41 PM Joe_Hildreth: Would you suggest with newer hardware that a preempt kernel will do fine for software stepping _OR_ PCI, PCIe and ethernet boards?
12:41 PM pcw_home: probably the easiest way to test LinuxCNC and Preempt-RT on random PC hardware is the Stretch/LinuxCNC test ISO
12:42 PM Joe_Hildreth: Where is that ISO located?
12:42 PM Joe_Hildreth: gloops, What went wrong?
12:43 PM pcw_home: My overall experience says Preempt-RT is not good for software stepping except on fairly fast systems
12:43 PM gloops: Joe_Hildreth i cant remember now, i didnt spend much time on it
12:43 PM pcw_home: http://www.linuxcnc.org/testing-stretch-rtpreempt/
12:45 PM pcw_home: thats a live image so you can test latency without installing or otherwise disturbing an existing OS installation
12:46 PM Joe_Hildreth: Thank you. Pulling a copy down now. Sounds like me being a newbie I shouldn't bother with compiling a RTAI kernel until I get some practice under my belt.
12:47 PM Joe_Hildreth: Thank you pcw_home.
01:00 PM pcw_home: Ha! Fedex finally found a lost shipment, 5 months later...
01:03 PM gloops: and i finally got the scale right on my X
01:09 PM Tom_L: pcw_home, just for you :) https://www.youtube.com/watch?v=BUdECzl2_bE
01:10 PM Tom_L: possible wrong language.. no sound ehre
01:10 PM Tom_L: here
01:12 PM pcw_home: :-)
01:31 PM CaptHindsight: https://www.youtube.com/watch?v=uxX1kA-nhZk I thought you'd post this one
02:10 PM Joe_Hildreth: I am running configure to compile LCNC, but I get this error, configure: error: Tk img::png not found! install with "sudo apt-get install libtk-img" but the library is installed. Any ideas?
02:10 PM gloops: pic in todays Telegraph https://postimg.cc/image/5os2vbbyz/ haha
02:11 PM gloops: there are channels for the inividual flavours of linux too Joe_Hildreth
02:11 PM gloops: individual
02:12 PM Joe_Hildreth: Gotcha, thanks gloops.
02:12 PM gloops: (not saying you shouldnt ask here mind)
02:16 PM JT-Shop: aww Joe left
02:16 PM gloops: hope he didnt take my comment the wrong way
02:17 PM gloops: i was saying like - there are experts on debian and so on who can probably help out with debian stuff too
02:17 PM JT-Shop: Joe_Hildreth if you read back later this it the steps I took to install Debian 9 with uspace https://paste.ubuntu.com/p/jRfMwXcWkk/
02:18 PM JT-Shop: it's actually gotten pretty easy now you can install preempt from synaptic in debian 9
02:18 PM Tom_L: yeah even i can do it
02:21 PM * JT-Shop goes to unload the truck
02:21 PM * Tom_L wonders if henry got a last meal...
02:30 PM gloops: hes in heaven with 32 hens of his own now
02:51 PM JT-Shop: his last meal was the night before
02:52 PM * JT-Shop thinks he is in my neighbors freezer...
03:55 PM Deejay: gn8
03:57 PM MarkusBec: hm i think i have a smi problem here with preempt
03:57 PM MarkusBec: i have tested smictrl better but still no good result
03:58 PM MarkusBec: peaks every 1-10 minuts
03:58 PM MarkusBec: any idea?
04:08 PM CaptHindsight: MarkusBec: does the BIOS let you turn off all speed stepping, thermal throttling, power management etc?
04:09 PM CaptHindsight: turn off all virtualization
04:10 PM MarkusBec: ich think it is allready deactivated
04:11 PM MarkusBec: but will cheak if i have somethink missed
04:11 PM CaptHindsight: MarkusBec: is it a new problem in that it did not do this before and then it started happening or is this a new mainboard and cpu that you are testing?
04:12 PM MarkusBec: new pc
04:12 PM MarkusBec: a hp
04:12 PM MarkusBec: i have the same setup from dell with now issues
04:13 PM MarkusBec: -w
04:13 PM CaptHindsight: HP pc's often have a BIOS that does not allow you to turn things off like power management
04:14 PM CaptHindsight: I have one here that gets >300K jitter with no options in the BIOS for killing power management
04:15 PM CaptHindsight: I also have a Gigabyte A88 (FM2) board that has >200K jitter only on the servo thread
04:16 PM MarkusBec: hmmm
04:16 PM CaptHindsight: it's easy for a BIOS dev to have options in the BIOS menu that don't actually do anything
04:16 PM MarkusBec: its over 1 000k jitter
04:17 PM CaptHindsight: ON/OFF are there just for looks
04:18 PM CaptHindsight: I took the APU and memory from the Gigabyte board and used it in an Asrock board with the same chipset and the jitter is fine
04:18 PM CaptHindsight: so different BIOS, same silicon, but different latency jitter
04:19 PM MarkusBec: i had this feeling with the HP before first stuarup
04:19 PM MarkusBec: t
04:20 PM CaptHindsight: I have not much luck with older off-lease HP systems and LCNC
04:20 PM CaptHindsight: same for Dell
04:20 PM CaptHindsight: other have gotten lucky
04:21 PM MarkusBec: with dell i head only 1 that was nogood
04:22 PM MarkusBec: old optiplex with core2duo
04:22 PM MarkusBec: but it was with out rt the slowest mashine i ever had
04:23 PM MarkusBec: the i5 or i7 optiplex ar ok
04:39 PM CaptHindsight: we used to use just about any Gigabyte or Asrock A85 mainboard with a 2-4 core APU and have jitter <6K
04:40 PM CaptHindsight: A88 is worse with 2 core APU's, don't have any older faster 4-core APU's to test with
04:40 PM CaptHindsight: but these are all 2-3 year old boards anyway
04:40 PM CaptHindsight: and AMD has all the new generation Ryzen chipsets and processors
04:41 PM CaptHindsight: we haven't optimized RTAI to work with any of them yet
04:54 PM BeachBumPete: hey guys is there a way to IMPORT G code into F360 to simulate?
05:17 PM BeachBumPete: got a piece of G code that was run on the CNC router we are buying that I want to simulate and also to help us generate a post processor for that machine.
05:59 PM homicidlbrainiac: Hey Seb, I just purchased a low-end PC, along with a parallel port PCI card and breakout board :)
06:00 PM homicidlbrainiac: Still working on understanding what I need to know about how RTAPI and HAL work together
06:00 PM homicidlbrainiac: I'm writing some code to work with freeRTOS on my other project I mentioned to you. It doesn't let you create tasks at a specific frequency, looks like tasks have to call a delay function
06:01 PM homicidlbrainiac: is that how the RTOS on linux works?
06:01 PM homicidlbrainiac: basically in freeRTOS, the individual tasks block for a certain specified time interval using a function called vTaskDelay()
06:02 PM homicidlbrainiac: I guess I could create a few tasks that run at specific frequencies, which one can hook other tasks into?
06:02 PM homicidlbrainiac: Also, these questions go for anyone that might know the answer
06:31 PM Tom_L: BeachBumPete, no
06:31 PM Tom_L: http://www.nc-corrector.inf.ua/index_EN.htm
06:31 PM Tom_L: the abrupt no came from here: https://forums.autodesk.com/t5/fusion-360-computer-aided/possible-in-free-360-manual-entry-import-g-code/td-p/5904103
06:34 PM BeachBumPete: I downloaded CNC simulator to try it but it has to be setup and I dont feel like spending the evening trying to sort thru the process..
06:34 PM BeachBumPete: have you used that nccorrector?
06:35 PM Tom_L: no i just got it from that link
06:35 PM Tom_L: we used n-see years back
06:35 PM BeachBumPete: figured
06:35 PM Tom_L: probably not even around anymore
06:36 PM BeachBumPete: I could have sworn I saw someone doing this dunno if it was fusion360 or what
06:36 PM BeachBumPete: the code program they sent looks kind of odd to me so I wanted to see if it simulated ok or not
06:37 PM gregcnc_: the thing is you need a sim that's coded for your control otherwise it doesn't prove much
06:37 PM Tom_L: not conversational is it?
06:38 PM BeachBumPete: I can post it if you want
06:38 PM skunkworks: open it in linuxcnc?
06:38 PM BeachBumPete: what was that text posting site again?
06:38 PM Tom_L: probably wouldn't do me much good but i'd look
06:38 PM Tom_L: lots of em
06:38 PM Tom_L: post.debian.org i think is one
06:38 PM Tom_L: no..
06:38 PM gregcnc_: I have hsm nc editor that came with HSMXpress i use it to prove my hand coded lathe stuff
06:38 PM BeachBumPete: nah that is not the one
06:39 PM Tom_L: pastebin.xxx
06:39 PM Tom_L: .ca
06:39 PM Tom_L: .com
06:39 PM BeachBumPete: that is it
06:39 PM Tom_L: i generally use ubuntu or debian
06:39 PM gregcnc_: https://ncviewer.com/ this didn't work for my Fanuc Lathe, but I think it was close for milling
06:40 PM BeachBumPete: https://pastebin.com/UT6r6pNr
06:43 PM skunkworks: weird - does it do some tool length touch off at the begining? It changes through all the tools
06:43 PM BeachBumPete: IKR
06:43 PM BeachBumPete: it is odd how they have that setup
06:44 PM BeachBumPete: I was wondering why and it confuses the hell out the CNC simulator
06:45 PM gregcnc_: what kind of machine is this?
06:45 PM BeachBumPete: hey that NC corrector works with it
06:45 PM Tom_L: i think it said it was freee
06:46 PM BeachBumPete: looks like it drills a bunch of holes and then routes a couple recatangular parts
06:47 PM Tom_L: does it give you a place to enter the material boundaries?
06:48 PM BeachBumPete: no idea yet
06:49 PM BeachBumPete: it appears that the nc thing just ignores the toolchanges at the beginning
06:49 PM BeachBumPete: then it runs thru the code
06:49 PM Tom_L: i thought you'd have it mastered by now :)
06:49 PM BeachBumPete: working on it LOL
06:49 PM BeachBumPete: wonder why it does that toolchange thing
06:49 PM BeachBumPete: odd
06:49 PM gregcnc_: what kind of machine?
06:49 PM Tom_L: not a prefetch thing is it?
06:49 PM gregcnc_: that's what I'm thinking
06:49 PM BeachBumPete: that is what I was wondering
06:50 PM BeachBumPete: this toolchanger is a carousel type so I dont know of any reason why it would do that
06:50 PM BeachBumPete: The machine is a 5x12 foot CR Onsrud Panel Pro CNC router
06:51 PM BeachBumPete: OH wait
06:51 PM BeachBumPete: I forgot this machine has an alternate drill head
06:51 PM BeachBumPete: it has the ability to drill 12 holes at once
06:52 PM gregcnc_: so it could be activating mutliple heads?
06:52 PM BeachBumPete: something like 9 in one direction and 3 in an perpendicular direction
06:52 PM BeachBumPete: possibly
06:54 PM BeachBumPete: https://www.youtube.com/watch?v=av7qRNa3Ot4 not the same machine but similar and you can see the drill head working
06:56 PM gregcnc_: which control?
06:56 PM BeachBumPete: its an AMC control apparently
06:59 PM pink_vampire: https://www.youtube.com/watch?v=9EhQruPMnTw
07:00 PM pink_vampire: the guy is sooo stupid
07:00 PM BeachBumPete: the G70 is a finish cycle here ?
07:01 PM BeachBumPete: It is strange how it is called up before the toolchanges
07:01 PM gregcnc_: I'd make sure to check the manuals for details.
07:02 PM BeachBumPete: well sure when it gets here
07:02 PM BeachBumPete: I was trying to get a post and a piece of code from the current owners so I can try to setup a post for Fusion360
07:03 PM BeachBumPete: before it arrives so I can get started testing once it is ready
07:04 PM BeachBumPete: N220 Z1.
07:04 PM BeachBumPete: from that line on it gets wierd agian
07:05 PM BeachBumPete: changes to tool zero
07:05 PM BeachBumPete: then tool 23
07:05 PM BeachBumPete: then tool 24
07:05 PM BeachBumPete: before it continues on its way
07:06 PM BeachBumPete: cannot imagine why you would want to do that
07:07 PM BeachBumPete: actually it does that all throughout the code
07:07 PM Tom_L: tool crib manager probably requested a tool count :D
07:07 PM BeachBumPete: Oh wait a minute
07:07 PM BeachBumPete: you dont think the code has to tell the carousel to turn to the next tool by cycling thru the tools do ya?
07:08 PM Tom_L: well which tool actually gets called up after the sequence?
07:08 PM BeachBumPete: also it only has a 12 tool carousel
07:08 PM BeachBumPete: so those are not positions just tool numbers as it should be
07:08 PM Tom_L: sure is odd
07:09 PM BeachBumPete: something else that is odd is that when it does this sometimes the tool callout is all on one line because they dont have line numbers
07:11 PM BeachBumPete: they feed at 700ipm in a few spots
07:11 PM Tom_L: faster than i can run
07:11 PM nubcake is now known as nubcake_

07:12 PM Tom_L: had an odd thing happen on the AC on my car
07:13 PM SpeedEvil is now known as Guest25919
07:13 PM BeachBumPete: I think I understand it now
07:13 PM Tom_L: was working fine last year
07:13 PM Tom_L: now it doesn't work at all
07:13 PM Tom_L: checked and half the clutch is missing
07:13 PM Tom_L: never seen that happen before
07:13 PM BeachBumPete: it APPEARS that those first bits of code calling up the tools are PROBABLY the drill head and I guess you can actuate the tools individually...
07:13 PM Tom_L: the center screw backed off and half it fell off
07:14 PM BeachBumPete: because if you look there is no spindle speed callout on any of them
07:14 PM BeachBumPete: until you get down to the lower number tools
07:14 PM Tom_L: does it have a manual?
07:14 PM BeachBumPete: which are PROBABLY in the carousel
07:14 PM BeachBumPete: the AC clutch is MISSING?
07:15 PM BitEvil is now known as SpeedEvil
07:15 PM Tom_L: looks like the inner half is
07:15 PM Tom_L: the compressor shaft is exposed and turns freely
07:15 PM BeachBumPete: well that is good
07:15 PM BeachBumPete: I know you can buy just the clutch
07:15 PM Tom_L: dunno what would cause it to back off though
07:15 PM BeachBumPete: well at least for some cars
07:15 PM Tom_L: yeah i checked on that but everybody says they replace the whole thing
07:16 PM BeachBumPete: ok
07:16 PM BeachBumPete: gotta break open the system then
07:16 PM Tom_L: but it's got good pressure and the shaft turns ok
07:16 PM Tom_L: i may try a clutch kit first
07:16 PM Tom_L: really odd
07:16 PM BeachBumPete: I am wondering how you would program that drill head in CAM
07:17 PM Tom_L: no idea
07:17 PM Tom_L: call up the tool number with the normal path i guess
07:17 PM BeachBumPete: boss says he will probably fly me up to CR ONsrud to get a little training on it
07:17 PM BeachBumPete: in NC
07:21 PM ziper: whats the difference between CAD models and the kind of models, say, video games use?
07:21 PM Tom_L: cad models are useful
07:22 PM ziper: is there any reason you can't convert from cad to the others?
07:22 PM Tom_L: depends on the format
07:23 PM Tom_L: there are standard formats for cad interchange
07:26 PM BeachBumPete: dunno it seems that a lot of animators are using 3d scans to build their animated models from and you can 3D print or machine from the same data
07:26 PM SpeedEvil: If the data they are using is good enough.
07:27 PM SpeedEvil: For example, game models may have legs not quite touching body, as it doesn't matter.
07:27 PM BeachBumPete: I THINK they modify the legs and arms etc of the model to be seperate entities and then animate those movements no?
07:28 PM BeachBumPete: I am no animator so I am not sure just what I have seen while researching this 3d scanner we are buying and how we will implement its data
