12:06 AM ripple: I am running a script pointing at /linuxcnc-dev/bin/halcmd The script works when I do execute it as user. However when I drive this same script with a web interface as www-data I get this error. RTAPI: ERROR: failed to map shmem RTAPI: Locked memory limit is 64KiB, recommended at least 20480KiB.
12:13 AM XXCoder: yeah no idea heh
12:13 AM XXCoder: now is quietest time
12:13 AM XXCoder: few hours evenually someone will be able to answer. maybe.
12:13 AM ripple: :) doesnt seem to be an issue on the linuxcnc just to one I did the build on
12:22 AM ripple: running this from the terminal works also so it must be something to do with www-data permissions or grouping?; php5 myscript.php;
12:25 AM station: XXCoder: for wood are belt driven 2m axis ok and the rest with 12x3 screw ok
12:26 AM station: or can x and y both be belt
12:28 AM XXCoder: meh dunno on belt as I onlu used ballscrews for my machine
12:28 AM XXCoder: I use belt on 3d printer but that hardly applies at all.
12:28 AM XXCoder: 3d printer experence zero side load.
12:28 AM XXCoder: (more or less)
12:30 AM XXCoder: chinese ballscrews is cheap
12:30 AM ripple: One other thing im not sure how to find, im trying to execute a bash script when I push a physical button on the machine. BUT the machine need to go to mdi mode for me to do this. How can I get a physical button attached to an input to signal a bash script?
12:30 AM XXCoder: just replace bearings or seriosly clean it out
12:31 AM ripple: The script is supposed to take the machine out of estop, poweron, and home it automatically. the problem is, it needs to be on before I can execute bash script, and so I cant execute the bash script to turn it on.
12:44 AM archivist: ripple, are you running machine kit or linuxcnc
12:44 AM ripple: linuxcnc
12:45 AM archivist: you will get more sense using python not bash scripts I thinl
12:45 AM archivist: think
12:45 AM ripple: I dont know how to python
12:46 AM archivist: nor me
12:48 AM ripple: I mean the script is nothing more than ; halcmd setp ***; sleep .1; halcmd setp ***; exit; it just seems silly the only way to execute a script is to go into mdi mode first.
12:48 AM ripple: so im doing this silly thing to see if I can get the glade interface to execute a script but take and input from linuxcnc aka big green physical button
12:48 AM ripple: an*^
12:50 AM archivist: connect real buttons direct to hal no scripts in the middle
12:54 AM MacGalempsy: python is not difficult. make the hal connections in the postgui.hal then make the buttons in the .xml
12:54 AM MacGalempsy: the most frustrating part is keeping tract of the </hbox> lines
12:55 AM ripple1: yeah but will let me execute halcmd do something exit;?
12:55 AM ripple1: with a physical button on the outside of the enclosure WITHOUT going into mdi mode?
12:56 AM MacGalempsy: which halcmd?
12:56 AM ripple1: setp
12:57 AM archivist: that is not what setp is for
12:57 AM ripple1: ?
12:57 AM MacGalempsy: setp is a parameter
12:58 AM ripple1: it works tho
12:58 AM MacGalempsy: what component are you using?
12:58 AM archivist: connect buttons to nets
12:59 AM ripple1: halcmd setp halui.machine.on TRUE; sleep .1; halcmd setp halui.machine.on FALSE;
01:00 AM archivist: this is not how people use setp
01:00 AM ripple1: I been attaching scripts like these to buttons on a php website to control the machine, poweron, home it, etc but I just want to be able to execute one of these with a physical button
01:01 AM ripple1: is there a different way I should be doing this?
01:01 AM MacGalempsy: with a button you would do something like net <signal name> <button address> -> halui.machine.on
01:02 AM MacGalempsy: button address would be your bob in pin
01:02 AM ripple1: yeah but I need it to to reset estop, turn it on, rehome it, download gcode file from set location, reload gcode and hit play.
01:02 AM ripple1: which it does all of this currently
01:02 AM ripple1: but instead of using a button on website I want it to be done with a physical button
01:04 AM archivist: use direct inputs no scripts
01:08 AM ripple1: I dont really think I have the knowledge to get one button to do all that as an input. Is there a good reason halcmd wont do this properly?
01:09 AM MacGalempsy: why not try classic ladder?
01:10 AM ripple1: I have another machine thats been up for about 4 years that uses these scripts when the computers boots, it automatically loads up linuxcnc, loads the programs, homes it and starts playing. Its been running about 4 years without keyboard mouse monitor etc. but i dont know a better way to do it
01:10 AM MacGalempsy: sounds like its time to start reading up
01:11 AM ripple1: I did have CL loaded but It seemed unneccessary when all I really need to have happen is execute script when button is pushed
01:12 AM MacGalempsy: did you try the forums yet? there may be an example there
01:13 AM ripple1: Yeah it seems everything I have found so far points to executing an mdi command
01:19 AM ripple1: I need to read up on how to reload the current file after modifications, I had just been doing this to remotely reload the program, I couldnt find another solution for it in the forums either axis-remote --reload;
01:22 AM MacGalempsy: archivist: on the Sprinter van, what are some of the things that require specific attention when investigating a potential used purchase?
01:25 AM archivist: MacGalempsy, not used one, seen plenty overtake me
01:26 AM MacGalempsy: for some reason i thought you had one. perhaps a miss identification on the cmm move motivational photos
01:27 AM archivist: that was an Iveco
01:27 AM MacGalempsy: the ones that motivated me to lift the edm solo
01:27 AM MacGalempsy: ah
01:28 AM MacGalempsy: found one with a sweet rack and 103k miles. but know nothing about what goes wrong with them
01:28 AM archivist: I suppose the best would be from an owner driver, more incentive to look after it
01:28 AM MacGalempsy: it is used by an a/c company. i guess ask about service invoices
01:29 AM MacGalempsy: http://lawton.craigslist.org/cto/5982604108.html
01:30 AM MacGalempsy: a liitle expanded steel on the rack and its ready to camp on
01:30 AM MacGalempsy: the decals will leave ghosts when removed
01:31 AM XXCoder: yeah
01:31 AM XXCoder: buy uhaul truck, nobody likes those, and rebuild engine and tranny yourself
01:31 AM XXCoder: cheap.
01:32 AM XXCoder: uhaul trucks tend to be held together by bailing wires and spit by time they retire em. they dont repair em well
01:32 AM MacGalempsy: lol. i need something for going to locations an hold all my crap including bike and moto
01:33 AM MacGalempsy: the wife started sending photos of interior conversions and stuff...
01:34 AM archivist: dodge is not sold here, sprinter is a Mercedes name
01:34 AM MacGalempsy: not sure the difference. i know mercedes owns dodge and the engines are the same
01:34 AM archivist: badge engineering
01:35 AM archivist: I thought dodge was gm
01:35 AM MacGalempsy: no. the big 3 are dodge/chrysler, gm, and ford
01:36 AM MacGalempsy: chrysler dailmer
01:36 AM ripple1: mopar?
01:36 AM MacGalempsy: i believe mopar is a dodge sport name
01:36 AM Wolf_: it is
01:36 AM MacGalempsy: like shelby is to mustang
01:36 AM ripple1: no
01:37 AM ripple1: its MOtor PARts
01:37 AM ripple1: its their product brand I suppose you could say
01:37 AM Wolf_: fits better with dailmer running things
01:37 AM MacGalempsy: like ac delco to gm
01:37 AM Wolf_: always going to need parts
01:38 AM MacGalempsy: lol. MOre PARts on order
01:38 AM ripple1: hahaha
01:38 AM ripple1: FoundOnRoadDead
01:39 AM ripple1: ford backwards I heard stood for. Driver Return On Foot
01:39 AM MacGalempsy: pretty much. i like the sprinter but also considering a f250 diesel
01:39 AM Wolf_: 6.7 is a beast
01:40 AM MacGalempsy: wife perfers a pickup, but i like the van idea.
01:40 AM archivist: get moooore crap in a van
01:40 AM MacGalempsy: those super long sprinters are sweet
01:41 AM MacGalempsy: yeah and stand up while packing it in
01:41 AM ripple1: marriage is about comprimise http://i265.photobucket.com/albums/ii228/olympiccop2002/c272_3.jpg
01:41 AM XXCoder: 50w wind prop I wonder what I can use it for lol
01:41 AM Wolf_: https://www.dropbox.com/s/47akeuzaozjdx06/IMG_3367.JPG?dl=0 got ford?
01:41 AM MacGalempsy: http://www.ebay.com/itm/252794150138
01:43 AM XXCoder: wolf yeah you got some of ford
01:43 AM MacGalempsy: ripple1: lol i just text that to her
01:43 AM Wolf_: that poor truck...
01:43 AM MacGalempsy: that ford looks like driver malfunction. meth?
01:44 AM ripple1: actually this isnt that bad of an idea
01:44 AM ripple1: http://gamt-hyundai.com/themes/hyundai-theme/assets/images/special_vehicle/hw036283.png
01:45 AM ripple1: I still dont think she would go for it
01:45 AM MacGalempsy: you could open a mobile stripclub with that one!
01:45 AM ripple1: genius
01:46 AM Wolf_: or something, kid was going to buy it and was working on fixing it or something, said a friend of his took it out, hit a honda at a intersection, truck went through a telephone pole sideways, ripped the rear driveshaft out, kid then put it in 4x and drove another 2 miles down the road and hit a tree that was about 6” wide at the base, tree didn’t move
01:47 AM XXCoder: what the fuck
01:47 AM XXCoder: hopefully that friend paid back
01:47 AM ripple1: with friends like that....
01:47 AM Wolf_: nope, lied to me when he picked it up, said he had a transferable tag w/ insurance
01:47 AM Wolf_: he didn’t
01:49 AM XXCoder: so you lost truck without money?
01:49 AM Wolf_: pretty much, traded it for a $700 beater, vs the $5500 I was going to sell it for
01:50 AM MacGalempsy: sounds like a beat down
01:50 AM Wolf_: not worth the jail time
01:50 AM MacGalempsy: small claims court
01:50 AM XXCoder: yeah that ones good idea
01:50 AM XXCoder: if guy dont come in, you win
01:51 AM Wolf_: lawyer money to go after a pos w/ no money
01:51 AM XXCoder: yu may not get money anyway but in least guy will have this truck hanging over him
01:51 AM XXCoder: Wolf_: small claims. no lawyer
01:51 AM XXCoder: bring paperwork and stuff
01:51 AM MacGalempsy: yeah. no lawyer
01:52 AM Wolf_: this was 3yrs ago now
01:52 AM MacGalempsy: oh. might be past the limit
01:52 AM XXCoder: ah slightly late . was thinking recent
01:52 AM Wolf_: truck is gone, so is the paperwork, it got rebuilt
01:54 AM ripple1: sigh* water under the bridge then.
01:55 AM Wolf_: now if the guy I work with would wreck my 2012 work truck, that would be great...
01:55 AM XXCoder: whats wrong with it
01:55 AM Wolf_: that its insured w/ $90k replacement value
01:56 AM Wolf_: =D
01:57 AM XXCoder: lol when I had van I hoped someone would hit it amd be in fault. its engine was failing
01:57 AM chatter29: hey guys
01:57 AM XXCoder: drove carefully though. van evenually died and now I have fpocus
01:57 AM XXCoder: oh great allah guy is here
01:58 AM XXCoder: good
01:58 AM ripple1: whats the gossip on him?
01:59 AM Wolf_: well, broke down and ordered the smoothie board, now if the damn aliexpess seller would get me a damn quote back
01:59 AM XXCoder: hes one that goes around and blabble about allah
01:59 AM Wolf_: aloha snackbar?
01:59 AM XXCoder: while waiting figure a way to diy laser tube? ;)
02:00 AM Wolf_: lol I’m not going to DIY a damn laser tube
02:00 AM ripple1: you would need to get a shark
02:02 AM Wolf_: that confused me for a moment because http://justaddsharks.co.uk
02:03 AM ripple1: well yeah because everyone knows about sharks with frickin laser beams attached to their heads
02:03 AM XXCoder: lol
02:03 AM Wolf_: http://justaddsharks.co.uk/cutters no, they actually sell laser cutters
02:03 AM ripple1: omg wolf didnt know about SWFLBATTH
02:04 AM Wolf_: yeah I know about the movie quote
02:04 AM ripple1: its cool, you dont have to lie to make friends
02:04 AM Wolf_: but that company is also highly recommended in a few laser groups
02:05 AM ripple1: that is super ironic though that image was there when I said sharks
02:05 AM ripple1: I dont laser so I guess it must be pretty common for you to see
02:06 AM Wolf_: been reading lot of info over the last week
02:06 AM SpeedEvil is now known as Guest99214
02:08 AM ripple1: gonna have to learn this and apply it :P https://www.youtube.com/watch?v=2MlJCMdD8MU
02:08 AM BitEvil is now known as SpeedEvil
02:09 AM XXCoder: I was wondering if that 4 wire connector would work for me for case connectors
02:10 AM XXCoder: maybe 6 wire actually, if I wanna also share limit switch wires
02:23 AM MacGalempsy: http://www.thebranfordgroup.com/dnn3/Employees/OnlineAuctionAdmin/CreativeThings,Inc/tabid/1627/Default.aspx
02:24 AM MacGalempsy: a local auction that i may be home for
02:24 AM MacGalempsy: kinda like that 6dof arm
02:26 AM MacGalempsy: also like the 4 lyons parts cabinets
02:26 AM MacGalempsy: those babies are like 2700 each empty
02:33 AM Deejay: moin
02:33 AM ripple1: Moin!
02:33 AM ripple1: =D
02:33 AM Deejay: :)
02:33 AM XXCoder: hey
02:34 AM MacGalempsy: hey Deejay- whats the weather like today?
02:34 AM ripple1: I know you guys come in here all the time and so you probably dont notice it, but this crowd is so much bigger than when I was installing EMC :P
02:35 AM Wolf_: e m what?
02:35 AM Deejay: emc is dead. long live linuxcnc!
02:35 AM Wolf_: http://i.imgur.com/ZRO2XBc.png
02:36 AM Deejay: MacGalempsy, about 7°C, little wind, no rain (yet)
02:36 AM ripple1: I never understood the namechange honestly
02:36 AM XXCoder: emc company sued
02:36 AM XXCoder: not "our" emc. other one
02:36 AM ripple1: oh, lame
02:36 AM Deejay: jo, evil company. sux
02:36 AM MacGalempsy: Deejay: sounds like the start of a chilly day. Where are you again?
02:36 AM ripple1: boo emc long live linuxcnc!
02:37 AM XXCoder: linuxcnc is better name anyway
02:37 AM XXCoder: still little bit genericish though
02:37 AM ripple1: I dunno I rarely even use it for cnc stuff its always some wonky setup
02:37 AM MacGalempsy: ahhh. easy to remember
02:39 AM Deejay: MacGalempsy, good old germany ;)
02:39 AM MacGalempsy: so the rig lost circulation at 2045 and now its 0209. the downhole motors packed off with lcm. looks like a few more days on lication
02:41 AM MacGalempsy: Deejay: any new linuxcnc inventions lately?
03:13 AM MacGalempsy: hmmm robot arm vs wifes love.... decisions, decisions...
03:13 AM ripple1: I cant find anything on how to execute a script with a button ahahah. I tried doing this thing with the signal or inputs but it looks really unsafe, is there a way to put timers in between these actions or do something intelligent other then what im doing? net greenbutton gladevcp.hal_button1 halui.machine.on halui.home-all halui.mode.auto halui.program.run
03:14 AM archivist: classicladder and hal have delays
03:14 AM XXCoder: MacGalempsy: well robot hand with fleshlight :P
03:14 AM MacGalempsy: lol
03:18 AM ripple1: thx archivist im reading about this delay, seems like a complete pain hahaha thats a ton of coding just to tell a button to sleep
03:18 AM archivist: sleep not= delay
03:18 AM ripple1: for now i think I will have to stick with halcmd to do this stuff, its worked for years and I cant think of any reason why it would be bad
03:19 AM archivist: set active/disable is logic
03:21 AM ripple1: there doesnt seem to be any input I can use to reload the program either, such as net button reloadprogram
03:35 AM MacGalempsy: ripple1 the wife said we should get the van pickup hybrid
03:35 AM MacGalempsy: lol. she must be drinking
03:36 AM XXCoder: weld truck back to regular van
03:36 AM XXCoder: done
04:00 AM ripple1: I cant believe how hard it is to figure this out. IF i push button on website php can execute a script, if I push button on linuxcnc with all its glory of inputs outputs pwms, steps, kinematics, realtime, gremlin, sensors, switches, pythons, etc, it cant do sometime as simple as "reload the gcode" if you push a button. Or reboot the computer perhaps
04:04 AM archivist: https://forum.linuxcnc.org/21-axis/29552-reload-program-through-pin
04:09 AM ripple1: archivist: lmao

04:09 AM ripple1: JT
04:09 AM ripple1: My Apologies.
04:09 AM ripple1: Did not realize one could "Hijack" a four year old defunct thread. :unsure:
04:09 AM ripple1: lmao
04:09 AM ripple1: I remember reading that awhile back and getting a kick out of it
04:10 AM Wolf_: damn dirty thread hijacker
04:13 AM ripple1: archivist andpugh put a rad little program together in python there did you see it?
04:13 AM ripple1: that should be exactly why I need to use if I learn how to make it work, thank you
04:13 AM ripple1: or course all it does it run a bash script :P
04:13 AM archivist: it is where google took me on a sensible search
04:14 AM ripple1: I read that thing over and over and didnt realize all he is is doing is calling on another bash script hahaha
04:14 AM ripple1: which is all pcw said to do prior in the thread but this was was with a pin instead of a MDI mode call
04:15 AM ripple1: I been on this post so many times and just looked right through what the python script was actually doing
04:31 AM MacGalempsy: I forgot how hilarious Brewster's Millions is
04:49 AM ripple1: archivist: this is wondrous and amazing and perfect, why isnt this little tool implemented into linuxcnc from the start THANK YOU ANNDYPUGH wherever you are. Ok so not, I can use GLADEVCP OR physical pushbuttons to bring up firefox and my text editor or fire off files to my webserver, muahahahahahaha
04:49 AM ripple1: so now*
04:56 AM ripple1: in japan they got these problems where their robots are dying in the radiation hole and all they want to do is look at this reactor, why not drill a hole into it from somewhere and aim a telescope in there? Is there maybe another way to use sound like echo location to model the room measure the progression of the melt? someone already thought of this right? :P
04:56 AM XXCoder: well might be able to do it with fiber optic len and cable.
04:56 AM XXCoder: nothing electics for long distance
04:56 AM ripple1: yeah light and sound seems the most logical o me
04:57 AM XXCoder: other is walking lead sphere
04:57 AM XXCoder: 3 inches all around
04:57 AM XXCoder: lens array has lead glass outside and inside normal glasses for focusing
04:57 AM ripple1: what if they made a submarine robot
04:58 AM XXCoder: the walking lead sphere'd be close thing to that
04:58 AM XXCoder: legs electrics is internal also, very heavily sheilded
04:58 AM XXCoder: it'd be also very heavy
04:58 AM XXCoder: cable dragging to keep powered
05:01 AM ripple1: I had an idea where you used like a canvas/rubber sack and fill it with lead/mercury and then a submarine robot inside and it propels its selve like this http://www.cheapdisabilityaids.co.uk/ekmps/shops/podcmedia/images/sea-life-water-snake-[2]-177-p.jpg
05:02 AM XXCoder: mecury'd be very damaging
05:02 AM ripple1: is it hot enough in there to keep leaded liquid? :)
05:02 AM ripple1: if so no mercury needed
05:04 AM XXCoder: http://snapmaker.com/kickstarter-lead.html
05:04 AM XXCoder: interesting
05:04 AM XXCoder: its likely hot enough to not keep mecury melted but vaporized
05:04 AM XXCoder: so yeah SUPER TOXIC
05:07 AM ripple1: XXCoder: http://www.tolomatic.com/?gclid=CIeXoIGWv9ICFYa2wAodl_4DvQ
05:08 AM ripple1: check out the linear things they do some are pretty slick
05:08 AM XXCoder: indeed.
05:08 AM XXCoder: well 200 bucks isnt too bad for laser 3d print and cnc mill combined
05:08 AM XXCoder: but will they deliver? I wonder
05:08 AM XXCoder: 500mW laser. wonder what it would be able to cut.
05:09 AM SpeedEvil: https://www.youtube.com/watch?v=5dpLOXeR7bk
05:10 AM XXCoder: 500w?
05:11 AM XXCoder: "Domain Suspension This domain has expired and is now suspended."
05:11 AM XXCoder: guess its gone
05:16 AM ripple1: I want these, I didnt know they made them http://www.tolomatic.com/products/product-details/erd-ss2-stainless-steel-electric-actuators-with-protective-motor-enclosure#/
05:16 AM XXCoder: linear motiom?
05:16 AM ripple1: yah
05:17 AM ripple1: rotary motor tho
05:17 AM XXCoder: wonder how precise it is lol
05:17 AM XXCoder: and repeative
05:17 AM ripple1: the ballscrew ones are probably great
05:17 AM ripple1: exlar makes some really heavy duty ones but they arent too accurate and not ballscrew
05:18 AM ripple1: schunk ballscrew slide with belt and motor is a good option I think tho
05:18 AM ripple1: affordable anyhow
05:21 AM ripple1: I been waiting for a cheap way to get my hands on hollow ballscrew assemblys
05:23 AM XXCoder: hollow ballscrews? why?
05:24 AM XXCoder: https://www.youtube.com/watch?v=arjRtCjI9AQ
05:24 AM XXCoder: dang
05:25 AM XXCoder: its years old too. nothing I know of has anything like that bending
05:25 AM sync_: XXCoder: to pump fluids through
05:25 AM ripple1: imagine this, hollow ballscrew, with a splined linear bearing/shaft (like a drillpress) and so each is on servos, it would be a very low profile linear actuated spindle
05:25 AM ripple1: yes and fluids
05:25 AM ripple1: :)
05:25 AM sync_: you can dynamically dampen them
05:25 AM sync_: to keep resonances out
05:26 AM sync_: by applying varying oil pressures
05:26 AM XXCoder: wow tha video.
05:26 AM ripple1: have you heard of that machine that vibrates the piss out of your drill and is supposed to make it last forever
05:26 AM XXCoder: guy made a card holder
05:27 AM ripple1: amazing
05:28 AM XXCoder: https://www.youtube.com/watch?v=xBUBUlOYRrc
05:28 AM ripple1: did he really just heat that plastic up in 4 spots and let gravity "melt the thing into a curved shape?"
05:28 AM XXCoder: always wondered how that was made
05:28 AM XXCoder: ripple1: why not? gravoty is free force
05:29 AM ripple1: clever things
05:53 AM jthornton: morning
05:54 AM XXCoder: yo
05:59 AM jthornton: burning any plastic today?
06:54 AM XXCoder: not for while jthornton
06:54 AM XXCoder: combation of cnc rputer working on and unablke to really work
07:04 AM R2E4_bevins: morning...... afternoon and evening....
07:04 AM XXCoder: and night, and morning again'
07:05 AM R2E4_bevins: normally drives when you power them up should have servo ready if no alarms?
07:06 AM R2E4_bevins: servo drives yaskawa in particular.
07:06 AM R2E4_bevins: I cant for the life of me figure out why they would not enable, then I found they were not sending servo ready
07:17 AM ripple1: R2E4_bevins: I thought I knew enough to get me by and when I ended up with "emerson 'ControlTechniques'" drives I found out I knew very little. They have everything including a place to insert how much you pay for electricity by kwh and it tells you how much you spent on electricity with the things
07:18 AM XXCoder: I need to try killowatt with my cnc router see how much it uses.
07:18 AM ripple1: page after page of variables you can tweak
07:18 AM R2E4_bevins: I have a control techniques inverter drive, it is amazing......
07:19 AM R2E4_bevins: I dont even use the servo ready.... I dont know what to do with it....lol
07:20 AM XXCoder: you made new HAL or what?
07:20 AM R2E4_bevins: No, a machine I might upgrade for someone, but I want to make it work with the old control first......
07:21 AM XXCoder: ahh dunno
07:21 AM R2E4_bevins: What do you guys do with the Servo-Ready signal?
07:21 AM ripple1: I like the options but I hate the design, the drives are 10" tall and the encoder cables fly one way, signals fly in from the top and then you need a windows computer and 200 programming box to change things(there are other ways to program but... still)
07:22 AM ripple1: R2E4_bevins: what model is it?
07:23 AM R2E4_bevins: my control techniques inverter or the yaskawa drives?
07:23 AM ripple1: yaskawa
07:23 AM R2E4_bevins: SGDB 30VD
07:23 AM R2E4_bevins: I have on my big machine yaskakawa cacr drives and they are amazing!!!!!!!
07:25 AM R2E4_bevins: I am running an 800lb X/Z head at 1500 inches per minute rapids, I can go up to 2400, but that scares me....lol
07:26 AM ripple1: R2E4_bevins: I would assume the servo ready is just an output to tell your controller its okay to start the program, unlock a brake, etc
07:27 AM R2E4_bevins: It uses air for brake compensation, but I tried enableing them manually and they wont enable. I thought it was because they werent ready.
07:28 AM R2E4_bevins: The guy paid 10,000.00 for the machine and it wont run..... and it has an opld control on it.
07:28 AM R2E4_bevins: I got everything ready to make it run but iot shows the drives are not ready. so it doesnt enable them.
07:29 AM R2E4_bevins: I've done 4 retrofits, and I dont use the servo ready on any of them.
07:29 AM ripple1: link to manual?
07:29 AM R2E4_bevins: When I power them I get servo ready,
07:31 AM R2E4_bevins: http://www.yaskawa.com.cn/technology/download/Manual/Servo/TSE-S800-16E.pdf
07:34 AM R2E4_bevins: . /S-RDY This signal indicates that the SERVOPACK is ready to receive servo ON signals.
07:34 AM R2E4_bevins: I dont get the /S-RDY signal, and there is no alarm
07:34 AM ripple1: you say you get servo ready when you power them on but you then need to send them an "enable" signal?
07:35 AM R2E4_bevins: I dont get the /S-RDY signal, and there is no alarm
07:35 AM R2E4_bevins: bizarre it says you get servo ready if no alarm on startup.
07:36 AM R2E4_bevins: all 4 drives are doing the same thing
07:36 AM R2E4_bevins: I could see how if only one was doing it but not al;l 4
07:37 AM R2E4_bevins: unless its a power problem but I get power light on.
07:39 AM R2E4_bevins: hey ripple1 , check section 3.7.8
07:43 AM ripple1: R2E4_bevins: see page 564
07:43 AM rob_h: being Yaskawa do they have a enable input like mon and /mon to enable main power , ones in my machine do and they dont do servo ready untill that is done
07:43 AM ripple1: I would assume someone reprogrammed these to something other than default factory settings
07:43 AM ripple1: can you compare?
07:48 AM R2E4_bevins: I will check. I didnt check the settings in the drive, but I gues I am gioing to have to now that I see it can be turned off.
07:49 AM R2E4_bevins: yes but I sent it an enable signal and they didnt enable.
07:50 AM ripple1: I wonder if the REVERSE DRIVE DISABLED and FORWARD DRIVE DISABLED pins are set to be N/C and if they are unhooked SERVO READY is FALSE
07:50 AM rob_h: servo ready is some times in estop chain in PLC depends how and when servo ready comes up
07:50 AM R2E4_bevins: That CN-01 either uses servo-on or not and when it is set to not, servo is allways on
07:50 AM rob_h: what control is it? cant you look at the PLC on the machine
07:51 AM R2E4_bevins: The contol is not seeing the servo on. I allready check the input module and the plc
07:51 AM R2E4_bevins: at the drive, it is not sending the servo-on
07:52 AM ripple1: do you know which all inputs were being used on the amp as it was installed before?
07:52 AM R2E4_bevins: It is not in the estop chain, I went through that and rectified his problems with the estop chain'
07:52 AM R2E4_bevins: yes
07:52 AM ripple1: can you list?
07:52 AM rob_h: i guess other things enable when you try and boot the machine from estop?
07:52 AM R2E4_bevins: alarm out, servo ready and enable servo
07:53 AM rob_h: on the mastsuura that has yaskawa stuff we have todo reset and power on to boot everything up,. unlike other machiens that power up when you take out of estop
07:53 AM ripple1: did it use any jumpers from one spot to another?
07:53 AM R2E4_bevins: oh yeah, there is a reset also
07:54 AM R2E4_bevins: I sent a reset and it didnt do anything
07:54 AM ripple1: I wonder if the reset is supposed to be N/C
07:54 AM ripple1: and so you have to keep it on?
07:54 AM ripple1: hahah doubt it
07:54 AM R2E4_bevins: no
07:54 AM rob_h: do you have R T power and do you have RST power, as RST should be through a contactor which is off untill machine is ready
07:54 AM rob_h: R AND T should be on as its logic power
07:55 AM R2E4_bevins: I have led power and I can go though and check so I assume logic power.
07:55 AM R2E4_bevins: I didnt check RT power physically
07:56 AM rob_h: i would see whats what first.. R and T id say is there if machine is on.. RST id exspect off untill you try to boot the machine up
07:56 AM rob_h: stops buss coming online and servos being powered untill the machine is ready todo so
07:57 AM rob_h: depends how the machine builder set things up too i only come half way into the convo here
07:57 AM R2E4_bevins: There is a million contacts for the estop chain, and all the contactors are in it. I wouldnt get machin on without any contactors fired.
07:58 AM R2E4_bevins: but I will check again......
07:59 AM rob_h: is this a retrofit or still the old control?
07:59 AM R2E4_bevins: its not retrofitted yet. Its going to though once I get this last issue resolved.
07:59 AM rob_h: whats the control now?
08:00 AM rob_h: no errors on the servo screen
08:00 AM ripple1: if you can get a printout of all the current parameters in the drives and compare them to the factory set parameters you would probably see some red flags
08:00 AM R2E4_bevins: It is on the old control. XNC computer running LynxOS a unix variant.
08:01 AM R2E4_bevins: I will check in the manuals if the company changed any settings from default, or a list of settings they changed.
08:03 AM ripple1: the fact that all 4 are acting the same is what suggests to me that they have been tweaked on
08:05 AM R2E4_bevins: The m,achien was not in working state so maybe they went in and tried to change things to get it running.
08:05 AM rob_h: or just all waiting for some signal that they are not getting if all the same
08:06 AM rob_h: if no alarms tho on anything spindle or servo drives yaskawa stuff is quite reliable
08:06 AM SpeedEvil: http://imgur.com/gallery/lflBA
08:06 AM R2E4_bevins: I thought of that and checked. I will check again, the wiring is very well documented...
08:07 AM R2E4_bevins: I know I have them on two of my machines I retrofitted. They are solid!!!
08:07 AM SpeedEvil: Big silver moose.
08:07 AM rob_h: who has to polish that thing
08:07 AM SpeedEvil: I assume it's actually stainless.
08:07 AM R2E4_bevins: I'd anodize it Blue!!!!
08:07 AM XXCoder: chrome covered? dunno lol
08:08 AM R2E4_bevins: ah stainless....
08:08 AM XXCoder: definitely not silver
08:08 AM station: galvanised pipe of 1/2 12.7 mm is enough for wood and mild aluminium cnc or should i get 1/1 25.4 mm
08:08 AM rob_h: what ever it is prob not be there long
08:11 AM R2E4_bevins: ok back to trying to get the accel app for the xhc-hbo4 working....
08:11 AM XXCoder: why? theres so many factors
08:11 AM SpeedEvil: 12.7mm pipe is going to be really quite flexible indeed
08:12 AM R2E4_bevins: use chrome alloy with a big wall.
08:14 AM SpeedEvil: Scaffolding pipe.
08:16 AM SpeedEvil: More seriously - cylindrical ways have issues.
08:16 AM jym: You can do it with 1/2" CONDUIT >:]
08:17 AM R2E4_bevins: or pvc pipe
08:17 AM SpeedEvil: Silicone.
08:17 AM jym: pool noodles!!!!
08:17 AM R2E4_bevins: lol, a nice bead of silicone.
08:18 AM station: LOL
08:22 AM ripple1: i want these lil guys
08:22 AM ripple1: http://www.actuonix.com/
08:23 AM ripple1: and what probably something like this? 7I54 Six channel 3A 40V Servo interface
08:23 AM R2E4_bevins: I am waiting for some cheap bigger faster acutators to come out. I want to do a racing simulator
08:24 AM XXCoder: bigger longer and uncut
08:24 AM ripple1: ebay has some cheap linear stuff
08:25 AM ripple1: http://www.ebay.com/itm/MO-1702-EXLAR-GSX20-0304-MCM-AB1-238-LINEAR-SERVO-ACTUATOR-/282127763837?hash=item41b020097d:g:pigAAOSwAYtWQQqS
08:25 AM R2E4_bevins: yes but nothing really bigger than the SCN5 and 6 stuff, and I need bigger than that
08:26 AM R2E4_bevins: whats the throw on it? they never say
08:28 AM ripple1: i dunno but i think you can break the part number down and dig it out of there
09:22 AM MrSunshine: ough broke a 3.5mm drill in a hole for the linear rails on the cnc machine .. any tips on how to remove it? sadly do not have any carbide drill bits or anything :/
09:24 AM jym: ice and a torch
09:24 AM MrSunshine: huh ? =)
09:25 AM jym: thermal expansion
09:25 AM jym: get one side cold, the other hot
09:25 AM jym: or just use a torh to heat the material which will expand then pull out the broken bit
09:26 AM ripple1: what material is the drill stuck in?
09:27 AM jym: ripple1: water ;)
09:27 AM MrSunshine: ripple1: steel
09:27 AM jym: MrSunshine: I wasn't joking abut the torch
09:28 AM jym: if you heat it, it will expand
09:28 AM ripple1: is it in a location you can drill from the backside and then push the old drill out from behind?
09:28 AM MrSunshine: jym: yeah im sure but how the heck am i supposed to jank it out when its below the surface .. remember .. 3.5mm in size
09:29 AM jym: MrSunshine: magnet? pick tool? scribe?
09:29 AM MrSunshine: ripple1: nope .. its in a square profile =)
09:29 AM MrSunshine: jym: how much would you say it need to be heated ? its a milled piece of the machine dont want it to change shape =)
09:29 AM SpeedEvil: MrSunshine: drill out with a better drill, tap
09:30 AM jym: MrSunshine: https://www.king-tool.com/img/tools/tool-groups/480/hook-pick-sets.jpg
09:30 AM MrSunshine: SpeedEvil: yeah thats what i was thinking .. only thing i have tho is a 5mm cobalt drill
09:30 AM ripple1: you'll just end up with two broken drills if its not carbide
09:31 AM SpeedEvil: indeed
09:31 AM jym: MrSunshine: Just a hand propane torch. You are not trying to cut the metal just heat it, take your time, it's not going to be a fast process.
09:31 AM SpeedEvil: jym: but it's down in teh hole
09:31 AM MrSunshine: well its a little bit below the surface
09:32 AM jym: MrSunshine: as you heat it GENTLY, begin to start prying it loos. When it is loose, you can use a pick tool or magnet , or just turn over and smack wit hammer
09:32 AM ripple1: air compressor and a little prodding might help
09:32 AM MrSunshine: jym: gonn have to try that then =)
09:32 AM SpeedEvil: I vaguely remember succeeding unexpectedly with this with a hack
09:32 AM jym: air and a face shield when it smacks you in the face =)
09:33 AM SpeedEvil: I drilled a little bit into the hole which the drill was broken into with a regular drill.
09:33 AM SpeedEvil: Then I took a cutoff wheel and slotted the bigger drill across the face to add clearance for the broken drill and continued drilling
09:34 AM ripple1: if you can drill the hole out extra big, tap the hole, screw in a plug you can reddrill and tap the plug to the 3.5mm size again
09:34 AM SpeedEvil: I could then get in with a little grinder on a dremel and clean off the remainder and grab the end of the drill
09:34 AM jym: MrSunshine: of just say fuck it, forget that hole and move on to the next one.
09:34 AM ripple1: ^
09:34 AM SpeedEvil: Indeed
09:34 AM MrSunshine: jym: hehe =)
09:34 AM ripple1: jym: whys he laughing
09:34 AM ripple1: :)
09:35 AM jym: ripple1: He's got the other half of the broken bit stuck in his nose
09:35 AM SpeedEvil: you might also try sricking a welding rod to it
09:36 AM ripple1: ooh even a lil mig welder wire would tac to that
09:37 AM ripple1: heres an idea that would probably never work, melt some solder drop in hole with copper wire cool and pull
09:48 AM jym: Just turn it upside down, heat it with a propane torch, and smack it with a hammer
10:17 AM * zeeshan thinks today will be fun
10:17 AM zeeshan: http://i.imgur.com/7Y9gxo9.png
10:17 AM zeeshan: will be making these :D
10:20 AM zeeshan: http://i.imgur.com/aMoB8vY.png
01:56 PM MrSunshine: Jymmm: if you are the same one ... heated it a bit and was in there with some sharp stuff and got it out =)
01:57 PM MrSunshine: flawless victory =)
02:05 PM R2E4_bevins: If I have a signal with an input and an output, and I want to energize the output, In python I have to set the pin and not the signal to true correct?
02:06 PM gregcnc: this is curious - flexodrill https://www.youtube.com/watch?v=ZwyVBsSOPJA
02:20 PM malcom2073: Wolf_ pm me your email I'll send you pictures of the rails
02:20 PM CaptHindsight: http://lalmek.se/en/products/flexodrill/
02:20 PM Wolf_: cool :)
02:35 PM R2E4_bevins: how do I get tool-prepare to run a python file?
02:41 PM * JT-Shop ponders that question a bit
02:42 PM R2E4_bevins: lol, I am trying to figure out how toolchange operation works. I want to run a python file when lcnc get a TX M6
02:51 PM cpresser: R2E4_bevins: perhaps as a userspace-hal-component.
02:51 PM cpresser: a toolchange will set some hal-bits, wire them up and be happy :)
02:55 PM JT-Shop: do you want to run something on Tool prepare?
02:55 PM R2E4_bevins: yes
02:56 PM JT-Shop: http://linuxcnc.org/docs/2.7/html/hal/halmodule.html
02:56 PM JT-Shop: like cpresser said
02:58 PM JT-Shop: another option but not using Tn is M1nn
02:59 PM R2E4_bevins: how about M6?
02:59 PM R2E4_bevins: thats remap I think
03:00 PM JT-Shop: http://linuxcnc.org/docs/2.7/html/man/man1/iocontrol.1.html
03:00 PM JT-Shop: those are the tool change hal bits
03:06 PM R2E4_bevins: I just want to test some python file now. Can I use M100 ?
03:33 PM Roguish_ is now known as Roguish
03:34 PM JT-Shop: yea
04:01 PM ripple1: R2E4_bevins: did you get your yaskawa figured out?
04:20 PM Cromaglious_: grrr my mini itx board is not liking the usb flash drive for booting... trying to get my system from 32bit to 64bit
04:21 PM Cromaglious_: anyone play with HAL for cartesian to polar conversion?
04:21 PM R2E4_bevins: no, its not in the same city.... I am working on trying to figure out the toolchange
04:24 PM Jymmm: MrSunshine: very cool
04:25 PM Jymmm: MrSunshine: oh should I say hawt?
04:28 PM Deejay: gn8
04:28 PM Jymmm: Deejay: gn9
04:32 PM Cromaglious_ is now known as Crom
04:34 PM Crom: MrSunshine, is the bit high enough you can get a prick punch to rotate it backwards a bit?
04:35 PM Crom: ahh you got it out
04:49 PM os1r1s: JT-Shop You told me yesterday that you never took your vise off your mill. I have a vise question for you. When milling an inch high alum block, do you think clamping the bottom 1/8 is enough to secure it?
04:51 PM Tom_L: should be fine
04:51 PM JT-Shop: well that depends on how square the block is and how hard your pushing on it with your cutting device
04:51 PM Tom_L: depends how big a cut you plan to take
04:51 PM JT-Shop: yup
04:51 PM Cromaglious_ is now known as Crom
04:51 PM Tom_L: you'll be the first to know if you push it too far
04:51 PM JT-Shop: and we will be second to know when it lands
04:51 PM os1r1s: Tom_L 1/8" deep cuts 1/8 width of cut
04:52 PM Tom_L: fine
04:52 PM JT-Shop: and the other condition is how good of a vise you have
04:57 PM os1r1s: JT-Shop Its a 5" glacern vise
04:58 PM os1r1s: Weighs about 50 lbs
04:58 PM Crom: finally running amd64 rtai kernel on the laptop. Now to find a ethernet smooth stepper board that affordable
05:06 PM JT-Shop: we don't use smooth steppers here
05:07 PM Crom: just found a express card parallel port that might work
05:10 PM JT-Shop: os1r1s: glacern makes a good vise I have one
05:11 PM os1r1s: I screwed up and bought the 5"
05:11 PM os1r1s: But its a monster
05:11 PM os1r1s: Think it will hold that alum block well?
05:11 PM JT-Shop: aye
05:13 PM JT-Shop: I have the 6" standard vise and two parlec 6" standard vises
05:13 PM JT-Shop: I used to wish I had gotten the premium vise so they could be close together but the space has come in useful
05:20 PM os1r1s: JT-Shop I want to turn mine sideways to maximize the on table space
05:20 PM Crom: just ordered a http://www.ecrater.com/p/19680187/express-card-expresscard-34mm-parallel for $15... hopefully it's what I want
05:20 PM os1r1s: Unfortunately the back part gets very tight against my column and really reduces my depth
05:20 PM os1r1s: Crom USually those are just USB over express
05:21 PM os1r1s: Crom So you have to find one that is true parallel over expresscard
05:21 PM Crom: like the Oxford 952 chip?
05:22 PM os1r1s: Crom Not sure about the chipsets. I haven't needed to look for one of those in a long time
05:26 PM Crom: well we'll see after I get it...
05:35 PM Crom: I just saw this on fleabay for around $210ish http://www.ebay.com/itm/Hollow-Shaft-Router-4th-Axis-A-Axis-ER32-Collet-3-20mm-CNC-Engraving-Machine-/261977712037
05:37 PM XXCoder: hey andypugh
05:38 PM andypugh: Hai
05:39 PM Crom: thinking about one of those for a Polar cnc setup. Rotary for theta (angle) with a linear actuator for r (radius / distance) mainly for plasma.
05:39 PM Crom: ER32 4thaxison ebay http://www.ebay.com/itm/Hollow-Shaft-Router-4th-Axis-A-Axis-ER32-Collet-3-20mm-CNC-Engraving-Machine-/261977712037
05:40 PM Crom: dang it where's my keyboard cleaner.. space bar is being flackey
05:41 PM andypugh: Crom: Looks weak
05:42 PM Crom: probably... with plasma though I'm thinking of running some wheels at the end of the arm
05:42 PM andypugh: Weak is no problem at all for Plasma.
05:42 PM andypugh: I missed that part
05:43 PM Crom: Have you seen AvE's video with the polar plasma arm?
05:44 PM Crom: been sitting here installing linuxcnc on this laptop so I can play with HAL for doing cartesian to polar conversion
05:44 PM andypugh: I find AvE hard to watch.
05:44 PM R2E4_bevins: ok I am doing some experimentation...... M100 via python imported linuxcnc and hal, I can use linuxcnc.stat and it works ok but cannot use hal.component_exists
05:45 PM R2E4_bevins: it says you cannot call before creating component. but the component has already been created.
05:46 PM Crom: I also ordered a ExpressCard LPT port for this machine hopefully it'll work with Linuxcnc $15
05:46 PM andypugh: (But that fact doesn’t stop me thinking that having AvE as one of _my_ subscribers is kind of cool)
05:46 PM Crom: true that!
05:47 PM malcom2073: andypugh: You're *the* "doing weird but interesting stuff with linuxcnc" guy :-P
05:48 PM Crom: just noticed it's been raining... YAY!
05:48 PM Crom: Herbs will be happy and the tomatoes are doing good too
06:25 PM Crom: brrrrr
06:26 PM XXCoder: pretty cheap 4th axis
06:26 PM XXCoder: too bad its so tall for my machine.
06:27 PM Crom: XXCoder, which one?
06:27 PM XXCoder: one you linked to, earlier one if theres more
06:27 PM XXCoder: oh no its second one, after andy entered
06:27 PM XXCoder: looks same
06:28 PM Crom: how can that be too tall?
06:28 PM XXCoder: heh my machine has 3 inch clearance
06:28 PM Crom: about what mine is also...
06:28 PM Crom: cnc3040
06:29 PM XXCoder: 2.56 inches
06:29 PM XXCoder: that actually fits under.
06:30 PM Crom: when i did my ar-15 lower buffer tube mount was too high
06:31 PM XXCoder: that gear wheel is taller, to unknown heigjt
06:31 PM Crom: I'd have to look but I had around 3/8" clearance under my Z carriage
06:31 PM XXCoder: not too bad probably have to be careful with tool hitting it
06:32 PM Crom: I have some AL bar stock I'm gonna make new side panels for my gantry out of
06:33 PM Crom: I had to take Z all the way up and poke the end mill in at an angle to get it into the er11 collet
06:33 PM XXCoder: nice! doing that usual mod of throw back to make more room for X?
06:33 PM XXCoder: increased offset
06:34 PM Crom: yep... I'm still having issue of loosing steps so I think I'm going to be getting a set of the leadshine hybrid steppers + driver for closed loop operation
06:35 PM XXCoder: losing steps hmm wonder if increased amps would fix that
06:35 PM Crom: might go the other way so I can get more offset off the end of the table so I can do things really tall in Z
06:35 PM XXCoder: that 4th axis is nice, saved link in "maybe"
06:37 PM Crom: i think I'm just going to have to make a completely new cnc bigger in X and Y and Z
06:38 PM XXCoder: wonder if you can add say one inch in that new gantry sides
06:38 PM XXCoder: not much but probably helpful and easier to get tools in
06:39 PM Crom: I was thinking of adding at least 2"
06:39 PM Crom: I have quite a bit of room to slide the spindle up and down
06:39 PM XXCoder: indeed
06:40 PM Crom: 4" would even be better... If I don't have enought Z, I can always block it up
06:40 PM XXCoder: can even do that to match parts or tools
06:40 PM XXCoder: though probably altering runout
06:41 PM Crom: it's a 3040... tramming isn't much of an issue
06:41 PM Crom: too much deflection to begin with...
06:41 PM XXCoder: whats settings you use to cut alum?
06:41 PM XXCoder: rpm and ipm and stuff like that
06:45 PM Crom: using a Arduino nano between the BOB and spindle speed control and I've been using 500 with 15mm/m with a 2 flute 4mm carbide endmill
06:45 PM XXCoder: hmm looks like you use different spindle than mine as 500 rpm I probably can stop with my hand
06:46 PM XXCoder: 2k is basically minium for light duty for mine
06:46 PM Crom: the PID speed control is a bit hunty.. so 500 to 1500rpm surges..
06:46 PM XXCoder: needs to tune pid a little
06:46 PM Crom: with out the PID yeah 500 has no torque.. with PID it's usable
06:47 PM XXCoder: would it be possible with tachmeter?
06:47 PM XXCoder: I have yet to install mine
06:47 PM Crom: ya think? PID using 0.015 .001 .0025
06:47 PM Crom: I'm using serial.print for rpms
06:47 PM XXCoder: I dont know enough about pid to actually tune it but hunting definely calls for tweaking
06:48 PM Crom: I've been searching for a good PID tuning page haven't found on yet...
06:48 PM XXCoder: theres pretty cheap tachmeters out there. or if you dont wanna physical led display, just grab induction and thin but pretty strong magnet
06:48 PM Crom: I have a 16x2LCD I'm thinking about using for a tach
06:49 PM Crom: I'm using a ebay hall effect sensor and 3 neod magnets in the fan of the spindle
06:49 PM XXCoder: nice nice
06:49 PM XXCoder: mine just one magnet
06:50 PM XXCoder: maybe guys in reprap know PID?
06:50 PM Crom: youtube robisydney is My user name there
06:50 PM XXCoder: 3d printers use a lot of PID
06:50 PM XXCoder: hotend control as well as hot bed control
06:50 PM Crom: they use PID for heaters... way to slow of response
06:50 PM XXCoder: yeah but maybe they know enough to help you adjust pid
06:50 PM Crom: I'll check
06:50 PM XXCoder: http://brettbeauregard.com/blog/2011/04/improving-the-beginners-pid-introduction/
06:51 PM XXCoder: yep reprap channel gthx has info heh
06:51 PM XXCoder: http://brettbeauregard.com/blog/2011/04/improving-the-beginners-pid-introduction/
06:51 PM XXCoder: err copy fail
06:51 PM XXCoder: <gthx> pid is Proportional, Integral, Derivative. A control algorithm used for temp control in some repraps. http://en.wikipedia.org/wiki/PID_controller -- A nice Arduino tutorial at http://goo.gl/vWQpE -- Marlin/Sprinter can auto tune your PID parameters: First run M303, your bot will heat up to 150, let it cycle several times, this will print out increasingly accurate pid
06:51 PM XXCoder: <gthx> values. Use M301 Px Ix Dx for new values and M500 to store and is also http://reprap.or and is also not as black magic as you might think. Here's a great video explaining it: https://www.youtube.com/watch?v=0vqWyramGy8
06:52 PM XXCoder: gthx is a bot that I want to also run in here evenually
06:52 PM XXCoder: amazing bot
06:53 PM XXCoder: that video is very nice so far
06:54 PM Crom: which video? newest?
06:54 PM malcom2073: Oh lame, I just found out that ebay bills you *later* for their fees. I figured the chunk that got taken out after the auction was their fees, apparently not
06:54 PM malcom2073: they took another 10% :/
06:54 PM XXCoder: last link in gthx comment
06:55 PM Crom: watching
06:55 PM XXCoder: mal that sucks. I hate "pay later" shit. its like hanging knife above head
06:55 PM gregcnc: ebay+paypal runs ~12% or so
06:55 PM malcom2073: Yeah, I think it was 13% all in all
06:55 PM malcom2073: Annoying and weird that they billed me a month later for it
06:56 PM gregcnc: I may not have checked since the last fee changes
06:56 PM gregcnc: you can' look at your account and see it right away
06:56 PM XXCoder: glad I dont sell there, been a long time since then
06:56 PM malcom2073: I wasn't aware that they take it out later. Years ago they took it out before giving you the money
06:57 PM XXCoder: bricklink dont even bill you till it gets over 20 dollars owed, and due is month after
06:57 PM XXCoder: heh I used to overpay by more than 20 bucks and not worry about it for months
06:57 PM gregcnc: not since I started in 2008 or so
06:58 PM malcom2073: It's probably been 10-15 years since I sold anything on it, so that's probably about right
06:58 PM gregcnc: no I've been suning ebay longer than that
06:58 PM gregcnc: using
06:58 PM XXCoder: mines umm 2002? dunno haven really looked.
06:58 PM malcom2073: Also possible that I don't remember that long ago :)
06:58 PM Tom_L: ole pharts
06:59 PM gregcnc: 2001
06:59 PM malcom2073: But it's still annoying, I'll have to put that on paypal credit to pay it, I already pulled the money out of paypal for the thing
06:59 PM Tom_L: and pp will charge you for that too
07:00 PM gregcnc: if you don't use it regularly, yeah it's a pain
07:00 PM malcom2073: I don't plan on regularly using it anyway
07:00 PM malcom2073: Most stuff I sell on craigslist and facebook
07:02 PM XXCoder: ahh 2004. thats right, its little bit newer than bricklink account
07:03 PM XXCoder: march 2004
07:03 PM XXCoder: april 2001 for bl
07:04 PM gregcnc: https://www.instagram.com/p/BRRmHAljEX6/
07:05 PM XXCoder: nice
07:05 PM gregcnc: webcelebrity machinist figures this guy makes
07:06 PM Crom: Great video!
07:07 PM Crom: looks like I need to use lower P, more D
07:08 PM XXCoder: heh sorry consider "d" usually is used for, that comment is funny
07:08 PM XXCoder: it is a great video
07:10 PM XXCoder: "he works in prison"
07:10 PM XXCoder: sometimes autocrapons is funny
07:11 PM XXCoder: that video is really fanastic when know calculus
07:15 PM andypugh: You don’t have to know much about calculus other than what an integral or a derivative is. You certainly don’t need to be able to calculate them.
07:15 PM XXCoder: andy sure but I can picture whats going on
07:15 PM XXCoder: makes it heck of a lot easier
07:17 PM gregcnc: me/ wishes he stuck it through calculus
07:17 PM XXCoder: hows ya andy
07:17 PM XXCoder: greg I loved calculus 1 and 2. 3 was really bad, due to sucky teacher.
07:18 PM XXCoder: it was second and last time I had a c
07:18 PM XXCoder: (college not high school, I fucked up a lot there)
07:18 PM gregcnc: I just got lazy and dropped it. I got exactly one homework point in that class. carried it in my pocket for a long time
07:19 PM andypugh: I liked differentiation, simple rules, always works. Integration, that needed too much imagination. “This looks like a T-substitution might help….”
07:20 PM Crom: time to go checkk on my downloads on the linuxcnc machine -- Currently trying to upgrade it from 32bit debian 7 to 64bit debian 8
07:21 PM XXCoder: canupgrade from 32bit to 64bit?
07:21 PM XXCoder: dang windows cant do that without complete reinstall lol
07:22 PM Crom: hard part is switching from 32bit libc to 64bit libc... need a live CD to do it... and the damn thing isn't booting to usb stick grrrrr
07:22 PM Crom: might have to bring it in and hook a cd up to it
07:23 PM XXCoder: heh
07:24 PM Crom: hmm i wonder if there is a difference in using a usb sd reader and a actaul usb flash drive
07:25 PM Crom: where the hell am I going to find a flash drive...
07:27 PM XXCoder: dunno stuff that sells tech crap tend to have some
07:28 PM XXCoder: 2 gb for 5 bucks or stuff like that
07:28 PM XXCoder: seen stores that dont discount old tech though, in 4 gb is max era, I saw 256 mb for 20 bucks
07:29 PM XXCoder: ironic because it was that store I also found 512 mb sticks for dollar each (I loved those sticks as it was fastanstic "I might lose it after handing over files" uses)
07:31 PM Crom: I have a 256MB... I need 1GB grrr
07:31 PM Crom: I have sd cards out the wazzo
07:35 PM gregcnc: does it format as bootable?
07:39 PM andypugh: I recently bought an actual USB DVD drive after failing to make a bootable USB stick. In some ways that drive and a stack of CDs is easier to keep on hand for various-version installs. And a lot less bother to boot from
07:40 PM Tom_L: usually
07:40 PM Tom_L: sometimes my USB DVD won't work for that either
07:41 PM Tom_L: a bit more fussy than a regular DVD
07:43 PM robertj: so suppose you want to build cnc router and we start by embedding the interface for the x axis for the rack and pinion in concrete
07:44 PM robertj: and we similary, make our x axis a big heavy something, either concrete or iron
07:44 PM robertj: and our z axis is a big chunk of iron
07:45 PM robertj: do we then have a shot at milling super-hard-stuff?
07:45 PM robertj: and we move everything slowly and spin the bit quite fast
07:47 PM andypugh: robertj: http://www.lathes.co.uk/multimachine/multimachine.pdf
07:47 PM andypugh: Sorry. Relevant, but not the actual link I was looking for
07:48 PM andypugh: I meant this one: https://flowxrgdotcom.files.wordpress.com/2011/07/new-method-of-building-lathes.pdf
07:49 PM robertj: so if you are not worried about cutting very slowly, can you get away with something closer to the several hundred pound mark instead of acouple tons
07:50 PM andypugh: Fast or slow is about spindle power. Accuracy is about rigidity and lack of backlash.
07:50 PM andypugh: Just buy that FP1 :-)
07:51 PM roycroft: and not all "hard stuff" wants high spindle speed and low feed
07:51 PM andypugh: Sorry, I mean F1. The FP1 was a different manufacturer.
07:51 PM roycroft: stainless steel, for example, wants the exact opposite
07:52 PM robertj: roycroft, hrmmm, why doesnt it like low feed?
07:52 PM roycroft: it work hardens very easily
07:52 PM andypugh: Depends on context. My mill has spindle speeds from 45 rpm to 1000 rpm. It’s rather too slow for any material with bits < 10mm
07:52 PM roycroft: if you feed slowly you will heat it up
07:53 PM robertj: roycroft, ahh
07:53 PM roycroft: something woodworkers tend not to understand, btw
07:53 PM roycroft: if you feed hardwood through your tablesaw too slowly you'll burn it
07:54 PM XXCoder: yeah done by feel
07:54 PM robertj: btw i did put in an offer on that F1 and got shot done, i'll make another offer in a few days
07:54 PM robertj: err shot down
07:54 PM XXCoder: pretty strightforward, just push so it cuts without it hitting wood too hard
07:54 PM XXCoder: theres pretty wide mirgin between burning and hitting wood too hard
07:54 PM roycroft: you cut as fast as you can without bogging the machine down
07:55 PM roycroft: if you do that and the wood still burns, and you have a sharp blade and are pushing in line with the blade, then you need a bigger table saw
07:55 PM robertj: andypugh, btw did you read the description on the f1 about the rewiring he was in the middle of?
07:56 PM roycroft: my overall point is that feeds and speeds don't fit a simple formula
07:56 PM andypugh: Yes. I assumed he was an idiot and that doing it right would be trivial :-)
07:58 PM XXCoder: Crom: so making sure, having spindle feedback and PID makes lower speeds more useful as if it slows down it applies more power?
07:58 PM Crom: yep!
07:58 PM XXCoder: great :D I want machine to cut alum evenually
07:59 PM Crom: mine is down right now... right in the middle of trying to install libc6-amd64
08:00 PM Crom: running 3.16.0 rtai amd64 kernel.. i386 is still main libs
08:01 PM Crom: so I have a 32 bit system capable of running 64bit bins... I want a 64bit system capable of running 32bit bins
08:22 PM gregcnc: andypugh I actually bought a USB floppy drive to bring programs to an old machine
08:32 PM XXCoder: wow!
08:32 PM XXCoder: usa wind power briefly crossed majority oif power generation in usa
08:32 PM XXCoder: we getting there :)
08:34 PM roycroft: we were
08:34 PM roycroft: now we're going back to expensive, dirty coal and oil
08:34 PM XXCoder: maybe. maybe not
08:35 PM roycroft: we are
08:35 PM XXCoder: market that they love so much is turning slowly against those not because its pollution but because of its increasily unprofitability
08:35 PM roycroft: since trump signed the executive order permitting coal mines to pollute rivers a couple coal mines have opened up again
08:35 PM roycroft: it
08:35 PM XXCoder: I cant wait to taste brown water and breathe brown air
08:36 PM XXCoder: im sure it will make me more hale
08:36 PM roycroft: is profitable if you are allowed to dump your garbage and make the taxpayers pay to clean up after you
08:37 PM SpeedEvil: Put the turbines in washington
08:38 PM SpeedEvil: http://forschung-energiespeicher.info/en/projektschau/gesamtliste/projekt-einzelansicht/95/Kugelpumpspeicher_unter_Wasser/ - related.
08:38 PM SpeedEvil: This is damn neat.
08:38 PM SpeedEvil: LArge concrete pressure vessels underwater, and high pressure turbines to store energy in them.
08:38 PM roycroft: we've developed some pretty nice water turbines in the northwet
08:38 PM XXCoder: just wire heat to power equipment to 45, we will have unlimited power.
08:38 PM SpeedEvil: Like pumped water storage, but enormously higher storage per volume
08:38 PM roycroft: they can generate power from both incoming and outgoing tides
08:39 PM roycroft: and are fish-friendly
08:39 PM XXCoder: not bad
08:39 PM roycroft: they can be parked just offshore with zero environmental impact
08:51 PM XXCoder: https://techcrunch.com/2017/03/02/nasa-released-a-ton-of-software-for-free-and-heres-some-you-should-try/
08:51 PM XXCoder: wow nice
08:56 PM MacGalempsy: good evening
08:56 PM MacGalempsy: 7
08:56 PM XXCoder: hey mac
08:58 PM MacGalempsy: exciting day so far?
08:58 PM XXCoder: not really
09:05 PM MacGalempsy: well the regained circulation and are going back to bottom to drill more
09:19 PM SpeedEvil: XXCoder: Or not.
09:19 PM SpeedEvil: Zed`: I for example, clicked on 'cart3d', filled in the form, made an account, and it said 'this software is only available in service to government contracts" or similar.
09:19 PM SpeedEvil: XXCoder:
09:19 PM XXCoder: heh different channel
09:22 PM SpeedEvil: I haven't looked at anything else. I suspect inviscid flow is going to be significantly less useful at hobby scales.
09:23 PM XXCoder: guess s
09:23 PM XXCoder: one of em is awesome though
09:23 PM XXCoder: 3d models
09:23 PM XXCoder: either 3d printing or milling
09:23 PM XXCoder: for example apollo landing moon terrain height
09:24 PM XXCoder: can mill it out from say wood, paint make tiny model
09:57 PM Crom: time to bring in the linuxcnc machineto boot off a DVD
09:58 PM XXCoder: heh my linuxcnc pc has dvd drive, it was old enough to have actually needed it.
09:59 PM roycroft: i have a portable dvd drive that i use when i need a dvd drive
10:00 PM roycroft: but i mostly put os images on usb sticks these days, and doo initial bootstrapping from those
10:00 PM roycroft: do
10:00 PM roycroft: i mostly use that dvd drive to rip new cds that i buy so i can put them in my music library
10:01 PM SpeedEvil: Home taping is killing music.
10:02 PM roycroft: nothing is killing music
10:02 PM roycroft: pirating and the like are killing the music recording industry
10:02 PM roycroft: but the artists are doing fine
10:02 PM roycroft: in many cases, better than ever
10:03 PM * Wolf_ listens to metallica that he downloaded from napster
10:03 PM roycroft: i thought we were discussing music :P
10:04 PM Wolf_: pre- ’90’s
10:05 PM roycroft: i still buy cds on a regular basis
10:05 PM roycroft: and vinyl for some things
10:05 PM XXCoder: I remember talking here before about making vinyls with cnc machine lol
10:06 PM roycroft: neil young would shoot you if you did that
10:06 PM Wolf_: would that count as digital mastering? lol
10:06 PM roycroft: absolutely
10:06 PM XXCoder: is that neil a vinyl hipster?
10:08 PM roycroft: neil refused to allow his albums to be released on cd for a long time because cds sounded so crappy
10:08 PM roycroft: and he's been ranting about lossy digital formats, specifically mp3, for ages
10:09 PM XXCoder: png is a non-lossy picture format, is there any such for sounds?
10:09 PM roycroft: he has invented his own portable music player that he says sounds orders of magnitude better than other digital formats
10:09 PM roycroft: aiff and wav
10:09 PM XXCoder: isnt wav "bitmap" of audio formats? no compression
10:09 PM roycroft: and some compression algorithms, like flac, do not introduce loss
10:10 PM zeeshan: XXCoder: flac
10:10 PM zeeshan: is a pretty common one
10:10 PM XXCoder: interesting
10:10 PM zeeshan: http://i.imgur.com/pFAmowv.jpg
10:10 PM roycroft: aiff and wav are non-compressed
10:10 PM zeeshan: its so nice to see this knife coming together
10:10 PM zeeshan: its roughed in
10:10 PM XXCoder: you made that?
10:10 PM XXCoder: pretty cool!
10:10 PM zeeshan: yessir
10:10 PM zeeshan: still need to do some handle blending
10:11 PM XXCoder: too bad my machinbe cant do harder metal
10:11 PM XXCoder: alum I think too soft for knife
10:11 PM zeeshan: this isnt too bad
10:11 PM zeeshan: its o1 steel but annealed
10:11 PM zeeshan: so easy to cut
10:11 PM Wolf_: most steel is too soft
10:11 PM zeeshan: after heat treat itll be around 58HRc
10:12 PM XXCoder: knifes usually are stainless steel right?
10:12 PM zeeshan: no
10:12 PM roycroft: NOOOOOOOOOOOOOOOOOO
10:12 PM zeeshan: i dont like stainless for a knife
10:12 PM roycroft: only cheap, crappy ones
10:12 PM XXCoder: really whats usual knife material?
10:12 PM roycroft: i guess most knives are cheap, crappy ones
10:13 PM zeeshan: theres tons
10:13 PM zeeshan: my benchmade uses s30v
10:13 PM zeeshan: which is a type of stainless
10:13 PM roycroft: good knives are made with damascus-like steel
10:13 PM zeeshan: what
10:13 PM zeeshan: lol
10:13 PM XXCoder: heh might make one out of alum just for heck of it. yes, it won't be usable really
10:13 PM Wolf_: no, over priced knives are made from damascus
10:13 PM XXCoder: also wood handles or hmm got idea of using bamboo wood
10:14 PM roycroft: bamboo is not wood :)
10:14 PM roycroft: it's grass
10:14 PM XXCoder: roycroft: ya forgot to add quotes
10:14 PM Wolf_: modern steels will out do old school stuff
10:14 PM zeeshan: i really dislike the look of damascus
10:14 PM roycroft: i like the look of well-done damascus
10:14 PM roycroft: but more importantly, it performs really well
10:14 PM XXCoder: roy trust me I know a lot about bamboo. I used to want to have bamboo farm
10:15 PM zeeshan: i like timascus more
10:15 PM zeeshan: for looks
10:15 PM zeeshan: :D
10:15 PM roycroft: there are other ways to make knife blades that perform really well
10:15 PM XXCoder: but ultimately decided not to, and too much money needed to even start,.
10:15 PM roycroft: folding mild steel over a hard steel core is a good way
10:15 PM Wolf_: ^ noq=w that I like for long blades
10:24 PM XXCoder: oh zee left
10:25 PM XXCoder: wanted to ask what he planned for handle lol
10:25 PM SpeedEvil: Damascus is in general mediochre.
10:25 PM SpeedEvil: Compared to modern knife steels.
10:25 PM SpeedEvil: Unless you're talking of the powder metallurgy damascus
10:28 PM roycroft: that south bend 9a seems to have been sold
10:28 PM roycroft: the one for $2250
10:29 PM roycroft: the ad has been pulled
10:47 PM Crom: burning debian 8.5 netinstall dvd
10:47 PM Crom: that was fast...
10:52 PM MacGalempsy: aww man I was wondering how hos survival knives are coming along
10:52 PM XXCoder: yeah
10:52 PM XXCoder: nice blade picture
10:53 PM XXCoder: wanted to ask about handle but left
10:53 PM XXCoder: meanie peer
11:02 PM MacGalempsy: i mean whats more important real life or irc? sheesh
11:03 PM XXCoder: lol
11:03 PM XXCoder: peer kicked zee out
11:03 PM XXCoder: he havent returned yet
11:18 PM roycroft: it's nigh on midnight where he is, xxcoder
11:24 PM Crom: anyonr have an example hal file with nontrivial kinematics?
11:25 PM Crom: the linuxcnc kinematics pdf is totally confusing
11:26 PM Crom: joints[0] = sqrt(x2 + y2); \n joints[1] = sqrt((Bx - pos->tran.x)*(Bx - pos->tran.x) + y2); \n return 0;
11:27 PM Crom: return 0; ????? so it's some sort of function... not seeing how to declare it though
11:37 PM * SpeedEvil wonders at http://www.ebay.co.uk/itm/HRC-3-Steel-Diamond-Indenter-Penetrator-For-Rockwell-Hardness-Testing-Tester-/222068170765?hash=item33b44b600d
11:38 PM SpeedEvil: Simple press + webcam = hardness measurement?
11:39 PM Wolf_: sounds simple enough
11:41 PM XXCoder: 9 pm roycroft
11:41 PM XXCoder: oh misunderstoof. yea
11:43 PM Crom: https://github.com/araisrobo/linuxcnc/tree/master/src/emc/kinematics gettting somewhere now
11:43 PM Wolf_: nice, aliexpress seller almost got my quote correct, only missing 3 parts on it lol
11:44 PM Crom: SpeedEvil, yep... a set force on a cone into the material being tested. size of divot == hardness so webcam is measuring the divot size
11:45 PM Wolf_: web cam using a optical comparator viewer?
11:45 PM SpeedEvil: More a USB microscope to measure the absolute size
11:46 PM SpeedEvil: Perhaps with a little a/b mount to put the centre of the cone at the centre of the field of view of the camera
11:47 PM Wolf_: yeah, just had that thought, really just needs to be on a fixed mount w/ known focal distance, or could just calibrate it with a paper
11:47 PM Wolf_: w/ know size scale
11:47 PM Wolf_: known*
11:47 PM Crom: yep
11:47 PM Crom: NYC CNC just did a video on a hand held one recently..
11:49 PM Crom: GGREBFLDGFLASBCC#^$%^*&#^#*&^$%#@$)%*# I have to burn a different debian netinst with firmware,,,, grrrr
11:49 PM Wolf_: I don’t burn anything anymore, I just load up a usb flashdrive using unetbootin
11:51 PM Crom: my POS itx board doesn't like booting off usb
11:51 PM Crom: unerbootin was a fail for me
11:51 PM Wolf_: weird
11:52 PM Wolf_: but I’m mostly using a 8gb drive w/ iso “burned” to it
11:53 PM Wolf_: oh yay, safari crashed and won’t reopen….
11:54 PM Wolf_: nice it won’t even force quit… damn osx…
