12:29 AM Crom: cncnoob: looks good, kinda pricey
12:32 AM MacGalempsy: Hello
12:34 AM cncnoob: Do you think there is a better option for cheaper?
12:39 AM hazzy: 3PH motor and VFD :)
12:40 AM cncnoob: that would be way to heavy :/
12:42 AM hazzy: Oh, that mill is tiny!
12:44 AM hazzy: You could use a treadmill motor and DC motor driver. That would have a good weigh/size to power ratio and be fairly cheap.
12:46 AM hazzy: You could probably use LCNC to control that quite easily, just put hall senors or an encoder on the spindle for feedback
12:48 AM CaptHindsight: hazzy: are you the author of hazzy?
12:48 AM CaptHindsight: just took a peek at it earlier today
12:49 AM hazzy: Yes I am!
12:49 AM hazzy: It is not even close to finished, but I am making progress
12:53 AM hazzy: I just finished making the terminal messages prettier: http://i.imgur.com/f4LzTDv.png
01:17 AM hazzy: GN8
01:37 AM pink_vampire: hi gloomy
01:49 AM MacGalempsy: hey capt
01:49 AM MacGalempsy: having fun yet?
01:50 AM MacGalempsy: hmm
02:17 AM IchGucksLive: Morning from Germany
02:18 AM IchGucksLive: off to garden
02:31 AM Deejay: moin
02:41 AM JesusAlos: Hi
03:02 AM jesseg: hey what do you guys use for CNC rotary tables -- how do you get low lash -- big harmonic drive?
03:02 AM jesseg: Is there a common essentially affordable option, or is it only for the big boys?
03:03 AM jesseg: Naturally I want to be able to do helical cuts with the rotary table moving live (i.e. not having to clamp the rotary table gibs for each cut..)
03:40 AM archivist: jesseg, I use vertex adjusted for min backlash and make sure the code only goes one direction do that it should be on one side of any play left
03:48 AM Crom: Jesseg: 4th axis using belts. Pretty much no back lash.
03:50 AM Crom: My motors can be set to 512000 steps per rev. Using a 2:1 reduction gives you pretty much no lash what so ever
03:51 AM Crom: Though at 512ksteps its very slow
04:02 AM archivist: if making gears some accuracy needed, no accuracy spec on belts
04:03 AM archivist: most of the rotaies have little/no spec, Vertex does have a usable spec
04:04 AM archivist: beware of microsteps there are not what you expect either
04:04 AM archivist: they
04:05 AM Crom: I'm using integrated closed loop steppers. Not really micro steps per se
04:06 AM archivist: can be fun measuring errors http://www.archivist.info/cnc/wormtest/
04:07 AM Crom: Be fun making worm gears sets on a belted 4th axis
04:27 AM IchGucksLive: Q: is there a DXF from the LCNC logo with tux holding a bit
04:27 AM IchGucksLive: bit=endmill
04:50 AM Longbow: Hello all!
04:51 AM Longbow: Should I be driving a spindle with PID control? I am now not using PID, but directly to analogOUT to VFD with softstart
04:54 AM archivist: not heard of anyone using pid for spindle
04:55 AM archivist: even those tapping or hobbing
04:57 AM pjm: i have a pid loop on my spindle but only to keep constant spindle speed under load
05:04 AM XXCoder: boo
05:21 AM Deejay: hey
05:22 AM XXCoder: is for horsies
05:26 AM jthornton: hay
05:28 AM XXCoder: is for saying hello
05:41 AM Longbow: hmm so I do NOT need PID for spindle? - I am asking because I am implementing spindle position - for G33 and M19 and ATC
05:42 AM Longbow: and it used TWO pids for the spindle. One for the velocity mode and another for position mode - ORIENT
05:42 AM XXCoder: im pretty sure you will always need pid but i could be wrong
05:43 AM Vq: I tried using a PID for spindle positioning but had little luck with it due to my drive not being able to handle low speeds.
05:44 AM Vq: I ended up writing a custom component for spindle orientation (based on orient).
05:44 AM Longbow: ORIENT - This component is designed to support a spindle orientation PID loop by providing a command value, and fit with the motion spindle-orient support pins to support the M19 code.
05:45 AM Longbow: I can write a component, but I would like to know what is BEST to use for spindle - PID or just direct analog signal to VFD?
05:45 AM archivist: g33 and the other "geared" options are just followers so the stability is less important
05:46 AM Longbow: I also need the spindle to orient to a specified angle for AutomaticToolChanger
05:46 AM Longbow: the spindle has a quadrature encoder with index
05:46 AM Vq: Longbow: Does your VFD have encoder feedback? If it does it may be capable of controling constant speed.
05:46 AM Longbow: yes - heidenhain ROD420
05:47 AM Longbow: But I am feeding the encoder signal to mesa boards. Not in the VFD
05:47 AM Vq: Then you will most surely want a PID loop in linuxcnc for controling the spindle velocity.
05:48 AM Longbow: till now it worked just fine by using only the analogout signal (+-10v)
05:48 AM Longbow: so I can make M19 work with no PID
05:54 AM * XXCoder facepalms. http://www.bbc.co.uk/news/world-asia-40421811
05:54 AM Tom_itx: Longbow, have a look at the carousel component
05:56 AM jthornton: I'm pretty sure if your drive/motor combination can't do position moves you can't use M19 or the carousel component
05:57 AM jthornton: something like a vector drive/motor can IIRC
06:00 AM MacGalempsy: morning guys
06:00 AM Vq: Good afternoon
06:01 AM MacGalempsy: XXCoder: read that earlier! she must have been blonde
06:01 AM XXCoder: blonds asian is very rare
07:02 AM Longbow: @jthornton: I am not sure. It is an old BOSCH SPM 25.
07:02 AM Longbow: can it not be done only using linuxcnc hal or is the drive mandatory?
09:22 AM JT-Shop: Longbow: if your drive is not capable of doing something software can't make it do it...
09:25 AM Roguish: pcw_mesa: pcw_home: have you seen these? http://www.elmomc.com in particular this one? http://www.elmomc.com/products/gold-twitter-servo-drive.htm
09:26 AM archivist: wtf is a qualitative Watt
09:28 AM roycroft: a watt that is shinier than can be measured
09:28 AM Vq: archivist: non-thermal?
09:29 AM Roguish: I think it's 'sales talk', but it could be 'alternate wattage' too.
09:29 AM archivist: I see a lot of marketing bs on there
09:29 AM roycroft: look
09:29 AM roycroft: that drive is clearly the best drive ever made
09:29 AM roycroft: it uses the word "gold"
09:29 AM roycroft: and "twitter"
09:29 AM roycroft: and it has better watts than anyone else
09:30 AM Vq: Nothing says fancy like twittering gold.
09:30 AM archivist: seem to be stealing lots of terms they done deserve
09:30 AM archivist: dont
09:30 AM roycroft: 2015 watts is actally 4000 "qualitative" watts in the headline
09:30 AM roycroft: and then right below it's 5000 "qualitative" watts
09:30 AM archivist: later they say 5000
09:31 AM roycroft: it's so great it gets 25% better while one is reading about it
09:31 AM archivist: not a precise statement anywhere
09:32 AM Roguish: ok, you guys giggle over it, but I have to deal with the 'gold twitter' thing. it's deep inside a project I'm working on.
09:32 AM roycroft: it may be a decent product
09:32 AM roycroft: but the advertising for it makes one want to run away from it as fast as possible
09:33 AM roycroft: it lies like a politician
09:33 AM archivist: using someone else's trademark for the product name is stretching it
09:34 AM archivist: 140 rev limit to its operation?
09:34 AM roycroft: roguish: i feel sorry for you if you have to deal with it
09:35 AM roycroft: i hope you have a qualitative watt meter to measure performance
09:35 AM Roguish: thanks, i'll take the sympathy....
09:39 AM JT-Shop: this is real http://www.fpeautomation.com/productpage.php?mfrid=28
09:43 AM Roguish: JT-Shop: i kinda like the integrated motors, for some things. use a Schneider for a project a while back.
09:53 AM sync: usually they are slow and underpowered
09:54 AM sync: but for easy automation jobs they are nice
09:55 AM Roguish: as I said, 'for some things'...... certainly not where lots of power is needed.
09:56 AM Roguish: though there a re some big ones too
09:56 AM sync: I have a few berger lahr icla drives
10:34 AM Todd_Z: All you guys snickering at the Elmo servo add. If you scrolled down a little farther there is another chart of model numbers and the R80/80 version is rated at 5kW cont.
10:36 AM roycroft: 5k "qualitative" watts?
10:37 AM Roguish: Todd_Z: I saw that. that's like 6.5 hp. out of that package? lot of heat...
10:38 AM Todd_Z: I'd be very suprised if the one in the picture is the 5kW one.
10:54 AM roycroft: wednesday morning
10:54 AM roycroft: bathroom window at the office wide open
10:54 AM roycroft: all the lights on
10:54 AM roycroft: front door unlocked
10:54 AM roycroft: nobody here
10:54 AM jesseg: Crom, cool -- so 2:1 belts onto a dual tapered roller bearing lathe spindle type of thing? or do you still have a worm drive in the mix?
10:54 AM Crom: My router mount http://picpaste.com/20170627_210054.jpg
10:55 AM Crom: Just straight belt. Big belt for sure to minimize stretch
10:55 AM archivist: I dont see a rotary there as he was asking about
10:57 AM Crom: It's under the table... people were making fun of my bonding wire clamp
11:10 AM jesseg: bonding wire is great stuff. Makes nice copper rivets too.
11:10 AM jesseg: Crom, what did you use for a bearing block for your rotary table?
11:25 AM jesseg: Crom, I'd love to see a pic if you have one handy :D
11:31 AM Crom: Lemme get up
11:53 AM Crom: waiting for my phone to upload to picpaste
11:53 AM jesseg: great thanks!
11:59 AM jesseg: hey what does it mean when an induction motor is labeled "55C RISE", "15 MIN"
12:00 PM jesseg: does that mean it rises by 55C every 15 minutes of continuous use?
12:00 PM jesseg: it's made in the early 60's as best as I can tell.
12:02 PM roycroft: i believe it means it will rise in temperature to 55 degrees above ambient temperature, and that it should be run for no longer than 15 minutes at a go
12:02 PM roycroft: that may mean a 25% duty cycle
12:02 PM roycroft: but i'm not sure about that
12:03 PM pink_vampire: hi
12:03 PM roycroft: i.e. run it no more than 15 minutes per hour
12:04 PM jesseg: well the way it gets hot that makes perfect sense
12:05 PM jesseg: as best as I can tell, it's manufactured 7-63. It's an old budgit brand electric chain hoist, but instead of using regular chain like they do nowdays, it uses motorcycle sprocket chain.. lol.
12:06 PM roycroft: compressor motors typically have a short duty cycle like that
12:06 PM roycroft: i could see a chain host using a compressor class motor
12:06 PM roycroft: one does not generally run a chain hoist continuously
12:07 PM jesseg: yeah, this only half a ton.
12:07 PM jesseg: and it weighs about 80 pounds :P
12:08 PM Crom: http://picpaste.com/20170628_091424-x4Bdf2tf.jpg
12:08 PM Crom: 3ish:1 reduction
12:08 PM jesseg: Interesting about compressor motors... I guess they figure it'll pump up and shut off.. Of course if you're doing anything that really uses much air they run all the time antyway.
12:09 PM jesseg: I recently got an old used englo portable air compressor. It has a 1.5HP motor that runs all the time, then when the pressure comes up to full, the compressor opens the intake valves so I guess that must be a continuous duty motor.
12:09 PM roycroft: i'll push mine beyond the rated duty cycle at times
12:09 PM jesseg: It is capacitor start/capacitor run
12:09 PM roycroft: but i'd never try to run it continuously
12:09 PM Crom: If your compressor is running that much you need to get a bigger compressor
12:09 PM jesseg: lol yeah
12:11 PM jesseg: Crom, super cool. What kind of bearing platform do you have for the larger pulley?
12:13 PM jesseg: Crom, I'm working on fixing up a 5HP Quincy 325 dual stage compressor but that's kind of a project because I intend to run it off the same 3 cylinder mitsubishi diesel engine I use to run a 3 phase 14kw gen
12:21 PM Crom: looks to be an anular bearing on the front and back.
12:22 PM Crom: so axial and thrust bearings in one
12:23 PM Crom: The preload is a bit hinky... looks like they put the belt pulley on then tightened it in place... I can't detect any slop
12:25 PM archivist: jesseg, what are you cutting, patterns or gears or what
12:26 PM jesseg: archivist, I'm a hobbiest so different things
12:27 PM jesseg: the last thing I cut was a 3-fingered shaft coupler for my dad's walk-behind hay raker
12:27 PM jesseg: but yeah gears, sprockets, cams, etc
12:28 PM archivist: one thing you might want to consider is the holding force needed and/or available with different drive methods
12:28 PM jesseg: yeah
12:28 PM jesseg: been thinking about that
12:29 PM jesseg: Hope to try some experiments on a small scale with this: http://www.ebay.com/itm/272621531574
12:30 PM IchGucksLive: hi all
12:30 PM jesseg: also considering loading my existing chinese indexer table up with valve grinding compound and lapping it till it is even and low lash
12:30 PM jesseg: Howdy IchGucksLive
12:31 PM archivist: that could ruin it :)
12:31 PM archivist: use a polishing paste not grinding
12:35 PM LeelooMinai_ is now known as LeelooMinai
12:36 PM evil_dan2wik is now known as dan2wik
12:37 PM andypugh: jesseg: http://bodgesoc.blogspot.co.uk/2017/05/harmonic.html
12:43 PM IchGucksLive: does someone know how made the tux icon with the endmill bit
12:47 PM andypugh: This one? http://fennetic.net/art/sketches/index.html
12:47 PM andypugh: Fenn
12:49 PM andypugh: Some more here
12:49 PM andypugh: https://forum.linuxcnc.org/show-your-stuff/32672-linuxcnc-logo?limitstart=0
12:57 PM IchGucksLive: andypugh: http://fab.cba.mit.edu/classes/961.09/people/jonathan/emc.html
12:57 PM IchGucksLive: that one
12:58 PM jesseg: andypugh, very interesting... thanks!
12:58 PM andypugh: jesseg: Which continent are you on? I have a spare casting…
12:58 PM andypugh: IchGucksLive: I think that is Fenn’s too.
01:00 PM hazzy: andypugh: I had not seen your blog post on the Harmonic Drive 4th Axis. You did that quick! Looks great.
01:01 PM jesseg: andypugh, USA :P
01:01 PM andypugh: hazzy: I have rather stalled on making it go round, though.
01:01 PM jesseg: andypugh, oh is that your blog post?!
01:01 PM andypugh: jesseg: My casting is in the UK, so it would cost more to send it than to make one locally.
01:02 PM jesseg: lol yeah
01:03 PM andypugh: But the FHA actuators really are a 4th-axis-in-waiting. Mainly because of the enormous crossed-roller bearing.
01:03 PM jesseg: actually I have a little gas fired crucible heater so I could probably actually melt some cast iron and cast my own, or maybe AL
01:03 PM IchGucksLive: andypugh: thanks
01:04 PM JT-Shop: you need oil fired for cast iron...
01:04 PM LeelooMinai: lol: https://www.youtube.com/watch?v=EUpwa0je6_Y
01:05 PM jesseg: JT-Shop, OK well for light duty stuff I could cast it out of old lawnmowers
01:06 PM JT-Shop: yea you can cast aluminum with propane no problem... just don't use wrought aluminum
01:12 PM jesseg: yeah I collect old lawnmower motors for casting purposes
01:12 PM jesseg: it seems to be reasonably nice for that
01:12 PM jesseg: and for machining in general :P
01:12 PM jesseg: extruded aluminum is kind of gummy. Too pure probably :P
01:13 PM JT-Shop: extruded doesn't have enough silicone to cast well, wheelium is best if you can process them
01:16 PM jesseg: cool
01:17 PM jesseg: well I have plenty of engine/transmission aluminum
01:17 PM * archivist imagines all the local cars up on bricks minus wheels
01:19 PM SpeedEvil: JT-Shop: silicon
01:19 PM SpeedEvil: sorry.
01:21 PM JT-Shop: I was close lol
01:23 PM Crom: wheelium.. I love that... much better grade of AL than Chinesium? What of Wheelium from China?
01:24 PM Crom: I wondering if I can melt AL using natural gas off a 1/2" gas fitting on my back wall
01:32 PM LeelooMinai: Then you will end up with Cromium:p
01:36 PM JT-Shop: wheelium is from cast car wheels
01:37 PM * JT-Shop wonders if he wrote down the back gauge setting for these parts on the press brake
01:44 PM IchGucksLive: GN8
02:00 PM narogon: hi everybody
02:01 PM narogon: i have the same problem as https://forum.linuxcnc.org/38-general-linuxcnc-questions/26078-m06-atc-problem-with-matsuura-fx5
02:01 PM narogon: do you think is there anyway to solve it using remap?
02:02 PM narogon: the question is if you prepare a tool
02:02 PM narogon: and after that select again the one that is in spindle
02:02 PM narogon: it remains the first one prepare to change, so when execute m06 change to that
02:04 PM Tom_itx: http://linuxcnc.org/docs/2.7/html/config/ini-config.html#sec:emcio-section
02:04 PM Tom_itx: not sure if that's relevant
02:08 PM Tom_itx: http://psha.org.ru/irc/%23emc/2013-04-25.html
02:08 PM Tom_itx: search for prefetch
02:08 PM Tom_itx: then as andy about it
02:09 PM Tom_itx: <andypugh> Tom_itx: ie, if you TN M6 on one line, then TN on the next line, the Hal pins wiggle in such a way as to allow the changer to locate the next tool, then change to it on the _next_ M6.
02:10 PM Tom_itx: so separate your Tx M6
02:13 PM Tom_itx: i've nothing to test it on
02:14 PM narogon: separating it doesn't changing anything
02:14 PM narogon: if you have a linuxcnc
02:14 PM narogon: you can try with the sim axis
02:15 PM narogon: adding RANDOM_TOOLCHANGER = 1 to EMCIO in .ini file
02:15 PM Tom_itx: it's not the first time this has come up
02:15 PM frankss: hi guys
02:16 PM narogon: yes, i've read some chats and the thread in linuxcnc forum
02:16 PM narogon: thats why i asked if it could be solved using remap
02:16 PM Tom_itx: andy wrote the carousel comp so maybe it could be modified to work
02:17 PM narogon: thats would be perfect
02:17 PM narogon: maybe it's a good idea creating a bug report
02:17 PM narogon: ?
02:18 PM Tom_itx: i don't know that this is a bug per se
02:18 PM Tom_itx: maybe a lacking feature :)
02:19 PM narogon: hehehe maybe a feature not complete
02:20 PM narogon: d
02:32 PM frankss: i've installed the linuxcnc debian distro and with a realtec ac887 codec i have no sound, anyone experienced the same?
02:33 PM phipli: evening
02:35 PM Deejay: switch your speakers on ;)
02:37 PM CaptHindsight: frankss: which version ISO?
02:38 PM CaptHindsight: but but but pulse audio is just supposed to work :)
02:39 PM CaptHindsight: frankss: could be all sorts of things, you have to start checking through all the audio settings
02:42 PM frankss: 2.7 iso linuxcnc debian wheezy distro
02:43 PM frankss: yeah i know.. ill probably give up lol, i just changed the hdd to the main pc cuz the old one with windows died
02:45 PM JT-Shop: hey phipli
02:53 PM phipli: evening JT-Shop
02:59 PM JT-Shop: got any more done on the automagic door?
03:14 PM phipli: nope :)
03:14 PM phipli: too much distractions
03:14 PM phipli: tonight I'm going to fix my internet banking, then I might chop off some aluminium for it
03:17 PM JT-Shop: I'm still trying to break down the ethercard example to it's basic components so I can understand it better lol
03:20 PM JT-Shop: I need to sell my Enco manual mill...
03:20 PM Tom_itx: how big is it?
03:27 PM JT-Shop: 36" table looks like 10" on Y
03:40 PM phipli: do you deliver?
03:41 PM JT-Shop: pickup only lol
03:50 PM JT-Shop: Wire is needed for the I2C?
03:54 PM phipli: yup
04:01 PM JT-Shop: ok I have 37 lines to get DHCP up and running :)
04:11 PM phipli: :)
04:18 PM JT-Shop: took 198 lines to pull out the NTP stuff
04:20 PM JT-Shop: now to see if I can write it in my style :)
04:28 PM Jymmm: Since when is "fugly" considered a "style"? lol
04:31 PM XXCoder: everything can be a style
04:34 PM phipli: It is three examples shoehorned together :)
04:35 PM JT-Shop: NTC, RTC and ?
04:36 PM Deejay: gn8
04:36 PM JT-Shop: goodnight Deejay
04:36 PM kyle___: g-code makes me sad
04:37 PM kyle___: assembly has the concept of mnemonics that make it easy to memorize opcodes
04:37 PM kyle___: but g-code is like the opposite of that
04:42 PM phipli: something adafruit... can't remember
04:43 PM phipli: I think there was ethernet and NTC from different sources
04:43 PM phipli: to get the DHCP working
05:17 PM Cromaglious_: I hate putting in invisible zipper without an invisible zipper foot
05:17 PM pflanze: Hello. We have installed linuxcnc via Debian Wheezy as shown on http://linuxcnc.org/docs/2.7/html/getting-started/getting-linuxcnc.html
05:17 PM Cromaglious_: You can't get close enough to the edge...
05:17 PM pflanze: When starting the linuxcnc user program it gives us an error, telling us that /dev/parport0 does not exist.
05:18 PM Cromaglious_: hiya pflanze
05:18 PM Cromaglious_: ls -laF /dev/*par* return anything?
05:18 PM pflanze: There's no /etc/modprobe.d/linuxcnc.conf as there should seem to be.
05:18 PM pflanze: Cromaglious_, nope
05:19 PM pflanze: The parport_pc module is loaded, and dmesg|grep parport shows 2 lines
05:20 PM pflanze: But no /dev/parport0 (and no /dev/lp0 either, although when I do "modprobe lp" then the latter will appear, but still no /dev/parport0)
05:20 PM Cromaglious_: hmm and I'm where I don't have a linux machine grr oh yes I do.. bbiab
05:27 PM Cromaglious_: and it has no lpt port Grrrr
05:32 PM Cromaglious_: cat /proc/ioports | grep -i par
05:36 PM Cromaglious_: pacman -Syu
05:37 PM Cromaglious_: and then reboot
05:53 PM pflanze: Cromaglious_, pacman? There's no such command installed.
05:53 PM pflanze: root@boxfordcnc:~ # cat /proc/ioports | grep -i par
05:53 PM pflanze: 0378-037a : parport0
05:54 PM Cromaglious_: sudo apt-cache search pacman
05:54 PM pflanze: That's a game: pacman - Chase Monsters in a Labyrinth
05:54 PM pflanze: You might mean the "pac" command.
05:54 PM Cromaglious_: archlinux has it... lemme find the debian equiv
05:55 PM LeelooMinai: Anyone knows wth AmazonWashingtonPost means? :/
05:56 PM Cromaglious_: ahh it's thier package manager
05:56 PM LeelooMinai: "Says after an hour of playing pacman" :p
05:57 PM Cromaglious_: https://www.archlinux.org/packages/core/i686/pacman/
05:58 PM Cromaglious_: LeelooMinai, besides they are getting slammed by the ransomware?
05:58 PM JT-Shop: a sad day for me my business partner died last night after a year long fight with cancer
05:58 PM LeelooMinai: Cromaglious_: Er, who is?
05:58 PM Cromaglious_: looking for the pacman man page to see what the -Syu do
06:00 PM LeelooMinai: I am trying to decode Trump tweet: "The #AmazonWashingtonPost, sometimes referred to as the guardian of Amazon not paying internet taxes (which they should) is FAKE NEWS!".
06:01 PM LeelooMinai: But it is beyond my skills...
06:01 PM Cromaglious_: ahh it's a red herring...
06:02 PM LeelooMinai: I wonder how many package managers there exist for Linux.
06:03 PM LeelooMinai: And why they could not agree on one...
06:03 PM LeelooMinai: One format that is.
06:04 PM Cromaglious_: pflanze, here's a page to read http://forums.debian.net/viewtopic.php?f=5&t=112712
06:07 PM LeelooMinai: Hmm, I used PL Preium construction adhesive and it supposedly has 24 hours cure time. Any idea if taking of clamps after half that will have very bad consequences?
06:08 PM andypugh: JT-Shop: Is the the Spyder business, or another one?
06:08 PM BeachBumPete: JT-Shop Very sorry to hear that man.
06:09 PM JT-Shop: in our J&J Automation business we formed many years ago he is my other brother John
06:10 PM JT-Shop: yea it bums me out except for his suffering is over now
06:10 PM BeachBumPete: he is your brother?
06:10 PM JT-Shop: no, we would just say that
06:10 PM JT-Shop: we are both named John
06:10 PM Tom_itx: JT, sorry to hear that..
06:10 PM BeachBumPete: ah well I am sure he is in a better place now sorry for your loss
06:14 PM * JT-Shop heads down to do some chicken herding then time to retire for the night
06:14 PM JT-Shop: goodnight
07:04 PM Vitran: :( Learning how to write my own hal and ini file. most is going over my head.
07:08 PM skunkworks: any specific questions?
07:08 PM Vitran: More learning how to do it
07:08 PM Vitran: The hardest programming I did was data analysis in Matlab
07:09 PM Vitran: I've always struggled with I/O stuff.
07:09 PM Vitran: But I made a list of things I need to do. Push a button to open a collet, push another to close it. That is what I am working on now
07:13 PM andypugh: Vitran: Don’t think of it as programming, it isn’t.
07:14 PM andypugh: When you were doing Matlab, did you ever yse Simulink?
07:14 PM Vitran: no
07:15 PM Vitran: mostly set up variables, bring in data, do operations on data, then process the output
07:15 PM Vitran: Not sure how to set up variables in LinuxCNC
07:15 PM andypugh: Ah, because HAL has a bit more in common with Simulink, but without the graphical bit.
07:15 PM Valen: Vitran: a list is a good place to start
07:16 PM andypugh: You don’t have any variables. (you might have some constants, typically pulled in from the INI file)
07:19 PM Vitran: So I have this collet. I push a button. I am thinking it is written as 'net collet <= input pin' where now collet is the variable and the input pin is hm2_5125.0.yadayadayada
07:19 PM Valen: not a variable
07:19 PM Vitran: and then somewhere else it reads that and outputs the signal
07:22 PM kyle___: I've become even crazier
07:22 PM andypugh: Yes, in HAL speak “collet” becomes your signal
07:22 PM kyle___: I'm going to build a microlathe out of lego technic parts
07:22 PM kyle___: this probably won't end well
07:23 PM Vitran: Can the world 'collet' now be called elsewhere? I don't want the spindle to turn on if the collet is open and the chuck flies out
07:24 PM Vitran: *word
07:25 PM Vitran: I am going through this to try and figure it out http://www.anderswallin.net/2006/11/jogging-emc2/
07:31 PM andypugh: yes, from now on yo can use collet as the _first_ foed of any other net command.
07:32 PM andypugh: (first word, that is)
07:32 PM pcw_mesa: I think of them as wire names
07:33 PM Vitran: wait, what would 'newsig collet bit' make if I link it to 'linksp collet hm2_5i25.0.yadayada.input-09'? When the button is depressed the bit 'collet' becomes a 1?
07:33 PM Vitran: And I need to make something to latch that to stay a 1
07:34 PM andypugh: You don’t need “newsig” or any of the link commands any more
07:34 PM pcw_mesa: newsig and linksp are basically obsolete
07:34 PM Vitran: Well, that was in the tutorial, so okay
07:35 PM pcw_mesa: there is a flip flop component
07:36 PM pcw_mesa: man flipflop
07:37 PM Vitran: I know labview quite well, so it is like that. Just not visual. I think I get it, but it will still be hard
07:37 PM pcw_mesa: 1/2 of a 7474 but active high set and clear (and cheaper)
07:41 PM Vitran: is there a list of the commands I can do in hal files?
07:42 PM Vitran: and/or/flipflop ect?

08:37 PM Tom_itx: just lost the hdd on the mill
08:37 PM Tom_itx: dunno if i have configs
08:37 PM CaptHindsight: add steppers to your 7i77 servo boards, just add encoders
08:38 PM CaptHindsight: who has ~4A stepper drives in stock and ships same day?
08:39 PM Tom_itx: non gecko?
08:39 PM CaptHindsight: automationtechnologiesinc.com webiste lied to me and they weren't in stock
08:39 PM CaptHindsight: better than TBAxxx
08:39 PM CaptHindsight: don't need gecko but will use them if they are in stock
08:40 PM CaptHindsight: http://www.automationtechnologiesinc.com/products-page/digital-stepper-motor-driver/kl-4042d-digital-bipolar-stepper-motor-driver-32-bit-dsp-based-duplicate/ would be ideal but not in stock

08:41 PM CaptHindsight: need it next day
08:43 PM CaptHindsight: I bet they are automation technologies but under a different account
08:43 PM CaptHindsight: Item location: Hoffman Estates, Illinois,
08:43 PM Tom_itx: i can't remember where i got my geckos but it wasn't them
08:43 PM Tom_itx: yeah
08:44 PM jdh: I got a couple of those KL digi drivers the other day to try at work
08:44 PM jdh: still sitting in the box.
08:44 PM jdh: also got a g540 to play with, I was surprised how *TINY* it is
08:44 PM CaptHindsight: the KL DSP drivers are great
08:45 PM CaptHindsight: the regular Keiling are OK

08:46 PM Tom_itx: order today, get it tomorrow...
08:47 PM jdh: I have a ton of Parker zeta drives, we keep buying them. with a matching single stack nema23, it's like $1,000 each
08:47 PM CaptHindsight: GM214 vs GM215
08:47 PM CaptHindsight: whats the diff?
08:47 PM jdh: 1.
08:47 PM Tom_itx: i'm using the 203v
08:48 PM Tom_itx: 214 is higher resolution?
08:48 PM CaptHindsight: Microstep Resolution: Up to 256 vs 10uS
08:48 PM LeelooMinai: jdh: When you wrote "we keep buying them", I was expecting they are $50 or something:)
08:49 PM CaptHindsight: so 256 uSteps with a 0.025" pitch screw =
08:49 PM jdh: LeelooMinai: nope, for most all purposes, a sub $100 drive/motor would be more than sufficient
08:49 PM jdh: but, change is hard.
08:50 PM CaptHindsight: 12nm resolution!
08:51 PM CaptHindsight: digiket carries Trinamic
08:51 PM CaptHindsight: Digikey even
08:52 PM LeelooMinai: 25 mil pich screw - that must be some non-cnc contraption...
08:52 PM LeelooMinai: It's barely over 0.5mm:/
08:54 PM LeelooMinai: lol at this headline: "98-year-old woman arrested at fossil fuel protest"
08:55 PM LeelooMinai: Maybe she thought that "fossil fuel" means turning old people into energy:p
09:02 PM CaptHindsight: had a Yaskawa 100W servo drive not behave
09:03 PM CaptHindsight: it enables and I can hear the coils in the motor quietly sqealing but it won't move even under no load
09:08 PM * LeelooMinai opens little package from China and finds a ceramic ball bearing for $3 inside
09:09 PM LeelooMinai: I think I ordered it just to play with it and see if I can feel any difference...
