12:27 AM CaptHindsight: https://www.automationtechnologiesinc.com/products-page/cnc-router/6040-cnc-router5-axis-engraver-engraving-machine-precision-ball-screw-1500w-spindle/ what do they use for low cost 4+ axis CAM?
12:31 AM CaptHindsight: is there some 5 axis engraving software out there?
12:31 AM CaptHindsight: from China or similar
12:31 AM XXCoder: I wish I knew
12:31 AM XXCoder: question 2 is not even answered lol
12:33 AM CaptHindsight: i think they just swap one of the linear axis for a rotary and then treat the engraving like a rectangle wrapped around a cylinder
12:34 AM CaptHindsight: XAZ for XYZ
12:38 AM XXCoder: thats one way to use multiaxis like 3 yeah but theres better ones, but so far I know all are out of home use range price
12:38 AM XXCoder: only one maybe is fusion
12:39 AM XXCoder: since its free for home
12:39 AM XXCoder: (income based)
12:40 AM pink_vampire: CaptHindsight: F360, HSMWORKS,
12:41 AM XXCoder: hsmworks is "techinically" free but it depends on solidworks
12:41 AM pink_vampire: free?? no
12:41 AM XXCoder: hm misremembered
12:41 AM pink_vampire: hsm express is free 2.5
12:42 AM pink_vampire: works give you the full 3d machining, and 4,5 axis
12:43 AM pink_vampire: CaptHindsight: I think the pocket NC i better option
12:44 AM pink_vampire: https://www.youtube.com/watch?v=dQLt-UOuw_w just read the comments LOL
12:45 AM pink_vampire: https://www.youtube.com/watch?v=FSuO-cwKeeo - very nice foam cutting
12:50 AM pink_vampire: XXCoder: https://www.youtube.com/watch?v=H1GuudT2Kis
12:51 AM XXCoder: looking
12:52 AM XXCoder: looks like china machine cutting part
12:52 AM XXCoder: earlier video is nice
12:53 AM pink_vampire: https://www.youtube.com/watch?v=DwoOYhp2txw
12:53 AM pink_vampire: the video title is LOL
12:56 AM XXCoder: first one comments can cut steel ti? yeaaah right :P
12:56 AM pink_vampire: i love the "semi" in the title
12:56 AM XXCoder: 4th video?
12:59 AM XXCoder: semi accuracy lol
01:00 AM pink_vampire: also curving inconel
01:01 AM XXCoder: weird
01:01 AM XXCoder: guy used tool without measuring length
01:03 AM pink_vampire: he is funny guy but the machine is nice.
01:41 AM pink_vampire: XXCoder: i took my emco vise apart
01:41 AM pink_vampire: do you want to see them?
01:42 AM XXCoder: sure why not
01:42 AM pink_vampire: or you want some measurements?
01:42 AM XXCoder: not really can always look up or ask you later. it rpobably will be over a year or more before finally can build a shop
01:44 AM pink_vampire: oh ok
01:44 AM pink_vampire: i'm clean all the aluminum dust
01:45 AM XXCoder: yep you gonna schedule maintenance or your equipment will schedule it for you lol
01:48 AM pink_vampire: i hate to work with dirty equipment
01:56 AM XXCoder: yeah work its always dirty but I clean whatever needed to preserve precision
01:57 AM pink_vampire: i clean it inside out
02:00 AM pink_vampire: all clean
02:03 AM XXCoder: :)
02:07 AM pink_vampire: the oiler is clogged
02:12 AM Loetmichel: *hmpf* quality services... out provider supplied us with a fiber "modem"/router for the company network... took about two years, today i came to the company an hour ago to be greeted by the boss "INTERNET ISNT WORKING! DO SOMETHING"... investigated: the cheap as fu** 15V 1A wallwart is dead. even melting traces on the little transformer inside... good thing we are an IT company... took a
02:12 AM Loetmichel: 12V 2A PSU that was surplus in the "junk box", thuned it up to 15V and installed it on the router. :-)
02:12 AM Deejay: moin
02:13 AM pink_vampire: Cleaned!!!!!!!!!
02:18 AM XXCoder: :)
02:19 AM XXCoder: lol Loetmichel
02:19 AM XXCoder: ghetto repairs
02:19 AM Loetmichel: indeed
02:20 AM Loetmichel: no cover on the psu whatsoever ;)
02:20 AM pink_vampire: Loetmichel: you are a legend
02:25 AM Loetmichel: pink_vampire: nope, just a bit above average ;)
02:26 AM XXCoder: plan to make cover?
02:26 AM XXCoder: temp solution tend to turn perment lol
02:28 AM Loetmichel: XXCoder: not yet. cowork just ordered a new PSU in a bit higher quality...
02:28 AM Loetmichel: lets see if that appears here..
02:29 AM XXCoder: lol ok
02:29 AM XXCoder: oh pink_vampire a second
02:30 AM XXCoder: https://imgur.com/a/14VF6AC
02:30 AM XXCoder: very clean machine
02:31 AM pink_vampire: WTF it was machined?
02:31 AM XXCoder: some weird material
02:32 AM XXCoder: its basically fake wood
02:32 AM pink_vampire: in your job?
02:32 AM XXCoder: yeah
02:33 AM syyl: haha
02:33 AM syyl: hose it down with cooleant ;)
02:33 AM syyl: wont make a mess at all :D
02:33 AM XXCoder: its long since been cleaned
02:33 AM XXCoder: this was right after I finished last part
02:33 AM Loetmichel: XXCoder: very clean indeed... i know that problem... plastics tend to do it even more... -> http://www.cyrom.org/palbum/main.php?g2_itemId=13888&g2_imageViewsIndex=1
02:34 AM XXCoder: yeah I remember that picture
02:34 AM XXCoder: I took that picture in 8/14 lol
02:35 AM Loetmichel: PVC isnt that nuch better... -> http://www.cyrom.org/palbum/main.php?g2_itemId=16429&g2_imageViewsIndex=1
02:35 AM XXCoder: know whats #1?
02:35 AM XXCoder: fiberglass
02:35 AM XXCoder: it forms into mud and if one mud spot dries on your skin...
02:35 AM XXCoder: itchy
02:36 AM Loetmichel: i know. dont get it into your lungs though
02:36 AM Loetmichel: its carcinogen
02:36 AM XXCoder: we use tooons coolant to keep dust down
02:36 AM XXCoder: one coworker was dumb enough to let it dry
02:37 AM XXCoder: I put stop to it, and carefully washed part and table with coolant by turn it on and jog it under it
02:37 AM XXCoder: moved it around till it was nice and dust-free
02:37 AM XXCoder: that guy isnt really type that listens so it will happen again. whatever
02:51 AM XXCoder: this is coooool https://imgur.com/gallery/Ci1BFLU
02:52 AM pink_vampire: XXCoder: is that considered a legit machining graphite?
02:53 AM XXCoder: not sure what you mean by legit
03:13 AM pink_vampire: i mean it is a pencil note graphite electrode
03:13 AM XXCoder: oh it looks like regular milling
03:13 AM XXCoder: probably even by linuxcnc image to gcode
03:14 AM Loetmichel: pencil core is usually graphite with some clay as a binder
03:14 AM pink_vampire: XXCoder: you are not getting my jokes :(
03:14 AM XXCoder: oh lol
03:15 AM XXCoder: sorry pretty down right now, getting sicker now bah
03:15 AM XXCoder: I was getting better and better but now..
03:17 AM pink_vampire: I have annoying problem with my emco vise, they not align with the T slots
03:18 AM XXCoder: why wont it align?
03:18 AM pink_vampire: let me take a pic
03:20 AM pink_vampire: https://i.imgur.com/0Bc8vDi.png
03:20 AM pink_vampire: i don't want to drill the vise
03:21 AM XXCoder: hm isnt those holes align if you move it towards you a little
03:21 AM pink_vampire: but also the position
05:36 AM jthornton: morning
05:36 AM XXCoder: hey
05:36 AM Tom_L: morning
05:37 AM pink_vampire: hi
05:38 AM Deejay: heya
05:42 AM XXCoder: check this out https://twitter.com/i/status/1028900133877030912
05:49 AM XXCoder: pink_vampire: something I wanted to try https://pbs.twimg.com/media/DeZ6TaxUwAA9U1-.jpg
05:50 AM pink_vampire: mee too
05:50 AM pink_vampire: one day.
05:50 AM pink_vampire: i even have ball endmills here with 1/8" shank just for trying injection molding.
05:50 AM jthornton: is that wax?
05:51 AM XXCoder: maybe, or plastic
05:51 AM XXCoder: either can be then used in wet sand casting
05:51 AM jthornton: for plastic you would have to inject it under pressure
05:51 AM XXCoder: hmm likely wax then
05:51 AM pink_vampire: jthornton: you can do small parts very easy
05:52 AM XXCoder: https://pbs.twimg.com/media/CrOtoGAVUAE58fb.jpg:large looks plastic
05:52 AM pink_vampire: with a piston that push by hand
05:52 AM XXCoder: they probably should redesign that object
05:52 AM jthornton: pink_vampire: have you done any small parts by hand?
05:54 AM pink_vampire: jthornton: https://www.youtube.com/watch?v=g2DVt-k_CU8
05:54 AM XXCoder: interesting!
05:54 AM pink_vampire: you can also use the Z axis
05:55 AM XXCoder: my machine is far too small for that
05:55 AM XXCoder: found at https://www.techkits.com/
05:55 AM XXCoder: $1800
05:55 AM pink_vampire: you remember that ? https://www.youtube.com/watch?v=PhtC-mwGe0I
05:56 AM jthornton: I don't trust putube videos when they say it's easy to use
05:57 AM XXCoder: 1800 bucks is bit expensive to buy tio play with lol
05:57 AM jthornton: there is a guy that makes tracks for battle bots and tanks and such somewhere
05:57 AM pink_vampire: XXCoder: it is just a piston, with a pid temperature controller..
05:58 AM XXCoder: yeah though I dont have skills to cobble one together
05:58 AM XXCoder: oh theres cheaper drill press based one
05:58 AM XXCoder: 595 bucks bit high
05:59 AM XXCoder: https://www.techkits.com/products/model-20a/model_20a.jpg
05:59 AM pink_vampire: bore some bar on the lathe and make the piston,
05:59 AM XXCoder: zero lathe skills
05:59 AM pink_vampire: ok..
05:59 AM XXCoder: (besides insert and remove parts and hit button lol)
06:00 AM pink_vampire: drill rod, and reamer
06:00 AM pink_vampire: I like the sugar dispenser
06:01 AM XXCoder: huh
06:01 AM * jthornton signs up for Medicare today lol
06:01 AM XXCoder: fun
06:01 AM pink_vampire: I saw some fancy cnc benchtop injection machine
06:01 AM XXCoder: I am not sure if im still in medicare or not
06:02 AM XXCoder: been long while lol
06:02 AM pink_vampire: https://www.youtube.com/watch?v=zTjbs3Hg2PA
06:02 AM XXCoder: damn I hate being sick
06:03 AM XXCoder: I miss old days when I just heal from sick in a day or so
06:03 AM XXCoder: aging sucks
06:04 AM pink_vampire: yeah
06:04 AM jthornton: takes forever to heal at my age
06:22 AM XXCoder: ugh!
06:22 AM XXCoder: I feel a lot weaker after going downstairs and folding my clothes
06:24 AM pink_vampire: why?
06:24 AM XXCoder: sick
06:28 AM jthornton: yea my new chicken door opened on time and the light came on
08:53 AM methods_: https://lulz.com/linux-devs-threaten-killswitch-coc-controversy-1252/
08:53 AM methods_: that escalated quickly...
09:08 AM flyback: good
09:09 AM flyback: fuck coc
09:09 AM rmu: there is some serious BS going on there
09:09 AM methods_: indeed
09:10 AM rmu: how is a CoC supposed to prevent rape?
09:12 AM methods_: this is bill gates crowning achvmnt
09:12 AM methods_: he's finally going to topple linux with sjw's
09:13 AM flyback: ugh\
09:13 AM flyback: those nutjobs make me look sane
09:14 AM rmu: time to dig out the HURD
09:15 AM Loetmichel: methods_: i dont think thats bill gates behind that
09:15 AM methods_: are you sure?
09:16 AM Loetmichel: sadly there are enough stupid people to do the SJW routine all on their own account.
09:16 AM methods_: nope
09:16 AM methods_: bill is doing this
09:16 AM methods_: he wants to destroy linux
09:16 AM methods_: his whole life has led to this
09:16 AM methods_: his crowning achvmnt
09:16 AM Loetmichel: "never assume malice where simple stupidity is sufficient as an explanation" ;)
09:17 AM methods_: #whoosh
09:17 AM Loetmichel: ?
09:17 AM methods_: exactly
09:18 AM Loetmichel: ah, i see
09:18 AM Loetmichel: nope, didnt went over my head. just not plausible as an explanation. not even as a joke
09:18 AM Loetmichel: <- german... ;)
09:31 AM rmu: this https://www.contributor-covenant.org/version/1/4/code-of-conduct.md doesn't look too bad (as in there are no points you could really argue against), it all depends how things are handled in practice
09:36 AM FinboySlick: Loetmichel: Hah, I was about to point out the German explanation ;)
09:37 AM FinboySlick: Loetmichel: But you're selling yourself short. You are *delightfully* german.
09:37 AM phaxx: rmu: yeah, being respectful (or at least, not actively hostile) to other people is kind of a low bar, and I'm glad Linux has (or may have, depending on how this shakes out) that now.
09:38 AM FinboySlick: phaxx: I can see how it may be dangerous to formalize the obvious.
09:39 AM phaxx: it's unfortunate that basic standards of behaviour need to be formalised, but *shrug*
09:42 AM rmu: "the only winning move is not to play"
09:43 AM phaxx: hopefully not, but if the cost (being nice to other people) is too high, then yeah, probably.
09:44 AM rmu: i mean not engage in discussions
09:44 AM phaxx: ah, maybe. debate can be good.
09:45 AM rmu: i didn't have a problem with linus saying something like "fuck you nvidia"
09:50 AM phaxx: yeah, I think care less about bile directed at companies.
09:51 AM rmu: debate about non-technical issues where no "benchmarking" is possible to get some emirical data tend do escalate quickly
09:52 AM phaxx: squishy human issues remain extremely difficult, I guess.
09:54 AM rmu: yeah, and mailinglists with high percentage of borderline-autistic people are not the proper place to solve them ;)
09:54 AM phaxx: ah, now we're getting to where you and I agree about the only winning move being not playing. :)
09:54 AM rmu: :)
09:59 AM methods_: well hopefully the whole thing won't go nuclear
10:00 AM phaxx: yeah
10:06 AM rmu: it won't. some self-important people (will) have there 5 minutes in the spotlight, then it will be business as usual, perhaps without most of linus' rants about stupid developers
10:08 AM FinboySlick: Taking the risk of it going nuclear to appease some people is debatable though.
10:09 AM rmu: look at the SCO allegations for the kind of money and time that would be involved if somebody decides to go to court
10:11 AM rmu: the logical outcome of this "crisis" would be for copyright assignment to the linux foundation or similar body
10:58 AM miss0r: evenin'
10:59 AM miss0r: Anyone in here know anything about the Bacho brand tool cart? (how is it quality wise?)
10:59 AM miss0r: evening fragalot
10:59 AM fragalot: hi
11:00 AM miss0r: fragalot: I was just asking in here if anyone knew what quality to expect from a bacho tool cart. Do you have any ideas?
11:00 AM fragalot: just tested the DRO's read-out, seems fine over 10mm
11:00 AM fragalot: bahco? middling quality
11:00 AM miss0r: nice
11:00 AM miss0r: yeah, that is the tool quality. What about the tool cart itself?
11:00 AM fragalot: :P
11:01 AM fragalot: the shop I used to work at ~11yrs ago (time flies!) used them
11:01 AM fragalot: was perfectly servicable
11:01 AM miss0r: ha.. Sounds good.
11:01 AM miss0r: My father got an offer for one, but did not know about the quality. So he asked me, and I told him I had no idea, but that I would ask in here ;)
11:01 AM fragalot: M-DRO is not aware of any software bugs, but they are filming demo videos on how to use it
11:02 AM fragalot: apparently the angle operation changes between XY and YZ
11:02 AM fragalot: god if I know why it asks for a diameter though
11:02 AM miss0r: yeah. That seems a bit off
11:02 AM miss0r: I wonder what their instruction video will look like
11:02 AM miss0r: :)
11:02 AM fragalot: not mentioning the YZ plane settings, probably
11:02 AM miss0r: Getting it to give results the one with the firmware you have is uncapable of :P
11:03 AM miss0r: incapable*
11:03 AM miss0r: :D
11:04 AM fragalot: shame it doesn't have a XZ plane, as far as I can tell
11:04 AM fragalot: would have been useful in horizontal mode
11:05 AM fragalot: (that said, I don't think i've ever used the angle function, :D)
11:06 AM miss0r: :D
11:10 AM gregcnc: so i thought I could dry a plastic jug by microwaving it
11:10 AM fragalot: well, you're not wrong
11:11 AM miss0r: depends on the plastic :D
11:11 AM gregcnc: it didn't melt, but the small drops of water didn't boil off either?
11:11 AM miss0r: well.. only depends on the plastic, if you have a need for it to keep its shape
11:11 AM fragalot: gregcnc: small droplets will never heat in a microwave
11:12 AM fragalot: they are too small to absorb the energy
11:12 AM gregcnc: ah, i figured it would be somethign related to size
11:13 AM fragalot: the wavelength is somewhere around 120mm iirc
11:13 AM fragalot: and the waves are not very well distributed
11:14 AM gregcnc: this microwave in particular has a odd pattern that makes soup sounds like it exploded ever ytime
11:58 AM fragalot: bahah
11:58 AM fragalot: miss0r: you know how i'm forced to use an iphone by work?
11:59 AM fragalot: miss0r: it's just tried to install ios12, which apparently took well over an hour.. and it's just dinged me to enter the passcode to finish the installation
11:59 AM fragalot: miss0r: after which it's shown "press Home to start recovery" <enter passcode> "attempting to recover your data"
12:35 PM CaptHindsight: https://www.automationtechnologiesinc.com/products-page/cnc-router/6040-cnc-router5-axis-engraver-engraving-machine-precision-ball-screw-1500w-spindle/ are these used mainly as 3-axis machines for engraving?
12:35 PM CaptHindsight: do they just swap a linear axis for a rotary?
12:36 PM CaptHindsight: XYZ becomes XBZ etc and treat the rectangle as wrapped around a cylinder
12:37 PM fragalot: it clearly says 5 axis
12:37 PM CaptHindsight: sure
12:37 PM CaptHindsight: but I doubt they use them that way
12:37 PM CaptHindsight: they don't use web based 5-axis CAM in China
12:40 PM Rab: I wonder how that column's constructed.
12:41 PM CaptHindsight: https://www.automationtechnologiesinc.com/wp-content/uploads/2016/08/3040C.jpg
12:43 PM CaptHindsight: from the page "4: Do you need any training for this"
12:43 PM CaptHindsight: no question mark

12:49 PM Wolfmetalfab is now known as Wolf__
12:49 PM fragalot: hehe
12:49 PM CaptHindsight: Rab: I'm sure it's at least some sort of hollow metal tube
12:53 PM CaptHindsight: https://bobcad.com/lp18/gl/shop-bobcad.php?source=PRICING_TOPNAV
12:59 PM CaptHindsight: http://www.scorchworks.com/Gcoderipper/gcoderipper.html#download
01:41 PM gloops: what pivots on that 5 axis?
01:43 PM fragalot: tilting rotary table
01:44 PM CaptHindsight: maybe there's a cracked version of mastercam floating around there
01:45 PM gloops: yeah there is
01:45 PM gloops: you can use f360 - but not the free version
01:45 PM gloops: or as archivist would advise - hand code it
01:52 PM CaptHindsight: gloops: I was wondering what buyers of those engravers use for 5 axis CAM
01:53 PM CaptHindsight: or if they just use 3-axis at a time
01:53 PM gloops: they dont, they spend 2 months on facebook pleading for information on 5 axis cam then sell it
01:54 PM gregcnc: gloops did you ever look into http://www.cnc-toolkit.com/
01:55 PM gloops: gregcnc is that the one that needs Rhino?
01:55 PM gregcnc: i don't think so, but I think it needs some odd old software
01:56 PM gloops: Although primarily developed and tested under 3DS MAX, the CNC Toolkit also works with Autodesk's Design Max and GMAX, which share the same core code.
01:56 PM gregcnc: i looked into it several years ago, nothing like a fully developed CAM
01:57 PM gloops: (GMAX is a free, limited version of 3DS MAX, but it can still use most of the CNC functions. The primary limitation of GMAX is no file export, although you can manually copy and paste the G-Code commands from the program's script listener to an external file approx. 10,000 characters at a time.
01:57 PM gloops: i never look further than the webpage
01:57 PM gloops: looked
02:04 PM gregcnc: this was done with cnctoolkit https://www.instagram.com/p/zoHk5wAZ5s/
02:07 PM gloops: well it obviously works then
02:39 PM CaptHindsight: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?WCH all of these I originally purchased back in ~2014 did not have the PCI_ID issue
02:40 PM CaptHindsight: all 3 of the latest ones have the issue
02:40 PM CaptHindsight: I'll try the pin strap fix to change PCI-ID's
02:40 PM CaptHindsight: a kernel mod for Debian may be loads of work
03:11 PM CaptHindsight: https://youtu.be/m82c8Xif8a0?t=8s does the voice fit the face?
03:16 PM cradek: wow, originally in a different language maybe?
03:17 PM XXCoder: lips moving seems nonenglish but same time dunno
03:29 PM CaptHindsight: their phone number has the South Korea country code

06:01 PM Spida_ is now known as Spida
06:02 PM gimps_ is now known as gimps
06:28 PM Tom_L: gregcnc was it you that mentioned not liking harvey tool thread mills?
06:28 PM Tom_L: if so, do you have a favorite?
06:39 PM enleth: CaptHindsight: actually you can use the free version of F360 for 5-axis setups if you qualify for a startup license, where AFAIR the only real requirement is that your income is below something like $200k/year
06:39 PM enleth: don't have to be a recently founded business or something to be considered a startup, just the income cap
06:44 PM gregcnc: Tom_L i've been using https://www.ebay.com/usr/redtool42
06:44 PM gregcnc: they have their own online shop
06:45 PM Tom_L: funny, i'm sitting here looking at their page
06:45 PM Tom_L: good quality?
06:46 PM CaptHindsight: enleth: I'm not looking for it. Just wondering what people use that buy those 5-axis Chinese engravers
06:46 PM gregcnc: seem OK
06:47 PM CaptHindsight: not usre if the Great Firewall of China allows access to F360
06:47 PM CaptHindsight: maybe they have a Chinese domain?
06:50 PM CaptHindsight: fing Google, now it thinks I'm in the UK with an IP address in the midwest USA
06:51 PM CaptHindsight: my searches are mostly UK sources now
06:57 PM enleth: CaptHindsight: no idea what they use there, just correcting what gloops said
06:57 PM enleth: if Autodesk didn't step on the communist regime's toes, it's probably accessible there, so that could very well be what some of them are using
06:58 PM enleth: and that's the only free-as-in-beer 5-axis CAD/CAM that I know of
06:59 PM CaptHindsight: why I'm wondering if they just use them as 3-axis machines and swap XYZ for XBZ and similar
06:59 PM andypugh: CaptHindsight: Interesting, at work I have the opposite problem
06:59 PM enleth: on the other hand, with the Chinese having the attitude towards copyright that they do, I wouldn't be surprised if pirated copies of expensive CAMs were in widespread commercial use
07:00 PM andypugh: It will give my location as Essex, UK on the very same page as it gives me shopping results from Michigan
07:00 PM CaptHindsight: yeah cracker MastermCommieCAM
07:00 PM CaptHindsight: cracker/cracked
07:00 PM enleth: CaptHindsight: XBZ is definitely officially a thing for some chinese CNC machines
07:01 PM CaptHindsight: andypugh: I've noticed this before when I would copy and past a link of yours
07:01 PM enleth: CaptHindsight: chinese laser cutters come with round stock rollers powered by a motor that you connect in place of the Y axis motor
07:01 PM CaptHindsight: my search results would become UK centric until I change IP's
07:01 PM enleth: to engrave bottles or whatever
07:02 PM CaptHindsight: same for flatbed inkjet
07:02 PM CaptHindsight: the cylinder adapter
07:02 PM CaptHindsight: converts your rectangle print area to the outside of a cylinder

07:24 PM andypugh: Or you can do it by hand coding ;-)
09:17 PM Tom_L: do they mix cobalt with carbide to take some of the brittleness out of the carbide?
09:25 PM tiwake: Tom_L: I know there is silicon carbide and tungsten carbide, donno about other types
09:30 PM djdelorie: boron carbide is a thing
09:37 PM Tom_L: i just saw some carbide cutters that advertized 10% cobalt
09:37 PM Tom_L: wasn't sure if that was a good thing or just standard tool carbide
09:56 PM trentster: Hi all when connecting a stepper driver alarm pin (Leadshine Am882) to the break out board, do i just configure an input pin like 16 = ESTOP and run a wire between the two?
09:56 PM trentster: 1) I am trying to get the machine to halt if a driver stalls.
09:56 PM trentster: 2) Do I wire each driver to the same input pin ?
09:56 PM pink_vampire: never worked with the Am882
09:58 PM pink_vampire: can you take a picture of the terminals? / text on them
09:59 PM pink_vampire: trentster: maybe this will be helpful http://www.mycncuk.com/threads/5566-Wiring-up-the-Alarm-output-on-Leadshine-AM882/page4
09:59 PM trentster: pink_vampire: thanks I had just found that myself, was busy reading it.
10:00 PM pink_vampire: there is a wiring diagram http://www.mycncuk.com/attachment.php?attachmentid=11686&d=1393164465
10:02 PM trentster: Thanks, I am not great at understanding wiring diagrams
10:02 PM trentster: it shows a ressitor there between enable Plus and fault plus ? is this correct?
10:03 PM pink_vampire: I think the "alarm" is just an output
10:03 PM trentster: and what is the flt- pin going to that looks like a little antennae(2 lines) ?
10:03 PM trentster: *3lines
10:04 PM trentster: so do i just take a wire from FLT+ to BOB input pin?
10:04 PM djdelorie: that symbol means "ground"
10:04 PM trentster: and config that pin as estop?
10:05 PM pink_vampire: maybe FLT is acronym to fault ?
10:06 PM trentster: yeah I assumed FLT means ALM
10:06 PM djdelorie: for other symbols, this might help: https://www.rapidtables.com/electric/electrical_symbols.html
10:06 PM pink_vampire: i think you can ignore the FLT- FLT+
10:07 PM pink_vampire: it is maybe like the ERR in the G320x
10:08 PM trentster: ok let me give it a try
10:08 PM trentster: back in a bit
10:10 PM pink_vampire: I think it's an output the show if something is wrong.
10:30 PM pink_vampire: someone try facing operation but with adaptive toolpath?
10:31 PM pink_vampire: I'm talking about facing with small endmills like 1/8" and about 30K rpm and more
10:39 PM Tom_L: doesn't seem that conventional
10:41 PM pink_vampire: I think I will be better against castling
10:43 PM pink_vampire: traditional right left machining will be 1:54, and adaptive spiral cut in constant load will be 1:44
11:00 PM trentster: pink_vampire: I have wired it up. The voltage on AM+ is 7.6V and then when the alarm goes off (e.g stalled motor) red light on driver flashes and voltage drops to 0V I have this connected to BOB input pin 10 and verified with multimeter that this pin see a drop to 0V as well.
11:01 PM trentster: I have told mymill.hal " net estop-ext <= parport.0.pin-10-in"
11:01 PM trentster: but when it stalls it does not stop the machine.
11:01 PM trentster: Do I need to add in some additional configs somewhere?
11:02 PM pink_vampire: is that a stepper or servo driver??
11:03 PM trentster: stepper
11:04 PM pink_vampire: so, why there is an ALARM signal?
11:06 PM trentster: its from the driver when the driver detects a stepper has stalled etc
11:06 PM pink_vampire: on a servo system the "Err / alarm" tel you there is some encoder problem and you the machine is off the position,
11:07 PM pink_vampire: but on stepper, I can't see why they have it.
11:07 PM trentster: Same thing really its to let linuxcnc know one of the drives has a problem and therefore the machine should go into error
11:07 PM trentster: same as what happens when a limit switch is hut.
11:07 PM trentster: *hit
11:08 PM pink_vampire: but what error?
11:09 PM pink_vampire: why you get the alarm signal to begin with?
11:12 PM veek: what's the difference between a tap bolt and a hex bolt
11:12 PM veek: hex is fully threaded? while the tap has a portion of the shank smooth?
11:13 PM veek: or is it the other way
11:13 PM trentster: pink_vampire: what difference does it make. e.g a motor stalled or an axis hit somethign and stalled the motor out.
11:14 PM pink_vampire: some error are not critical,
11:14 PM trentster: The driver running that motor is mart and goes into error and can output that info the linuxcnc so that the other axis stop moving until the error is resolved.
11:14 PM Wolf__: nice thought, but if the stepper system needs fault out for stall, its probably going to lose steps
11:14 PM trentster: pink_vampire: who cares if its critical or not, thats subjective, I am asking how to get it to work.
11:15 PM pink_vampire: you need to make like OR gate in hal
11:15 PM pink_vampire: and connect the to the signal
11:17 PM pink_vampire: trentster: I had similar problem with the probe and the tool setter
11:17 PM trentster: whats the procedure for conencting an estop?
11:17 PM pink_vampire: 2 pins that act as "probe"
11:17 PM trentster: it should be indentical
11:18 PM pink_vampire: one sec I will look at my hal code
11:18 PM pink_vampire: the machine is running right now
11:18 PM Wolf__: veek: https://www.portlandbolt.com/technical/faqs/tap-bolt-vs-cap-screw/
11:18 PM trentster: pink_vampire: thanks mate
11:20 PM pink_vampire: it is a 3 axis machine?
11:23 PM trentster: yeah
11:23 PM trentster: 3 axis
11:23 PM Wolf__: my next build is a 1 axis cnc
11:23 PM pink_vampire: so I think you can take my hal file, and edit the probe input to be your e-stop input
11:24 PM pink_vampire: and you will get 2 e-stop inputs
11:26 PM trentster: thanks
11:26 PM trentster: I will take a look
11:26 PM pink_vampire: the machining is done
11:27 PM pink_vampire: amazing finish!
11:27 PM veek: Wolf__, thanks
11:29 PM pink_vampire: ok
11:29 PM pink_vampire: this is how it is work
11:29 PM pink_vampire: net my-sigin1 or2.0.in0 <= parport.1.pin-10-in-not
11:29 PM pink_vampire: net my-sigin2 or2.0.in1 <= parport.1.pin-11-in
11:30 PM trentster: is that the only configs you have for those?
11:30 PM trentster: no other entries needed?
11:30 PM pink_vampire: it is take the lpt pins 10 ans 11 and push them in to the OR inputs
11:31 PM pink_vampire: then i connect the probe-input the the OR
11:31 PM pink_vampire: net both-on motion.probe-input <= or2.0.out
11:32 PM trentster: ok thanks
11:32 PM trentster: I will play again.
11:32 PM pink_vampire: the both-on is part of the stacklight - so i think you can ignore it.
11:35 PM pink_vampire: but to be honest, just get some simple 7430 (74ls30 74HC30) and connect all your error stuff to it, and just connect the out put of it to your linux cnc,
11:35 PM ziper: _unreal_, whats the best material to use for a core that will get dissolved later
11:36 PM pink_vampire: or you can use like arduino nano, and monitor temperature and stuff, and show them on some nice lcd
11:36 PM pink_vampire: ziper: you mean like low temperature alloy??
11:37 PM ziper: pink_vampire, FRP layup over a core
11:38 PM pink_vampire: not sure
11:39 PM pink_vampire: but on my fiberglass stuff i'm using pva mold release
11:40 PM pink_vampire: but I'm not sure what do you mean by "core"
11:40 PM ziper: the geometry of the part would preclude simply sliding out the core
11:40 PM Wolf__: foam board maybe?
11:46 PM pink_vampire: https://i.imgur.com/CsM6itr.png surface fish - as machined adaptive facing with constant load
11:52 PM miss0r: trentster: You around?
11:52 PM miss0r: pink_vampire: Looks realy reflective. How does the surface feel?
11:54 PM pink_vampire: like glass
11:55 PM miss0r: nice
11:56 PM pink_vampire: i love the HF
11:57 PM pink_vampire: why there is no undo / history for the dro
11:58 PM miss0r: some have
11:58 PM miss0r: depends on the DRO
11:58 PM pink_vampire: linux cnc dro
