12:30 AM MacGalempsy: hello
12:32 AM MacGalempsy: back to drilling here in OK
01:20 AM Cromaglious_: Hi Mac.. Going home, be there in 1/2 hour or so
01:41 AM Crom: home
01:51 AM IchGucksLive: Morning
01:55 AM IchGucksLive: till later
02:23 AM Deejay: moin
03:50 AM MacGalempsy: slow times around here
05:00 AM XXCoder: booyaa
05:03 AM MacGalempsy: yo
05:03 AM MacGalempsy: what going on?
05:05 AM XXCoder: not much
05:05 AM MacGalempsy: same here. my back is kind of sore
05:05 AM XXCoder: lucky ya, mine hurts as usual lol
05:06 AM MacGalempsy: there are so many little component boards to the drone
05:07 AM XXCoder: the board, 4 motor controllers and battery
05:10 AM R2E4_bevins1: mornin,afternoon, evening
05:10 AM MacGalempsy: yo
05:10 AM XXCoder: the r2d2
05:10 AM MacGalempsy: morning here
05:10 AM XXCoder: *hey
05:10 AM MacGalempsy: osd
05:10 AM MacGalempsy: receiver
05:10 AM MacGalempsy: psd
05:11 AM MacGalempsy: pdb
05:11 AM MacGalempsy: xyz
05:11 AM MacGalempsy: 1230
05:14 AM R2E4_bevins1: man I suck at graphics
05:15 AM MacGalempsy: how bad? like a cheap hooker or a oreck xl?
05:16 AM R2E4_bevins1: no, just like a cheap hooker....
05:17 AM R2E4_bevins1: Trying to do a decent looking buttopn panel....
05:17 AM MacGalempsy: just keep trying, you'll improve
05:18 AM MacGalempsy: i always like drawing in illustrator over photoshop
05:18 AM MacGalempsy: if its really simple, i just use powerpoint and take a screenshot
05:21 AM XXCoder: mac you should try inkscape]
05:24 AM R2E4_bevins1: I am using coreldraw
05:24 AM jthornton: morning
05:24 AM XXCoder: hey jt
05:24 AM R2E4_bevins1: I have inkscape..... problem is software wont make you better graphics artist, it just helps if your creative....
05:25 AM R2E4_bevins1: Hi JT
05:25 AM XXCoder: inkscapes great on simple vector gfx
05:25 AM XXCoder: for accurate 2d drafting I use freecad's wonderous sketch
05:25 AM XXCoder: it should be also standalone, but I has no idea how to do that.
05:26 AM R2E4_bevins1: Its the whole graphics thing, artistic, I can handle the software but the software does what you tell it to do......
05:26 AM R2E4_bevins1: I have autocad for drafting....
05:28 AM R2E4_bevins1: you guys have a high res version of the linuxcnc logo?
05:28 AM XXCoder: theres one somewhere
05:28 AM XXCoder: its surpising hard to find. maybe wiki has it
05:28 AM * archivist points again at doc source
05:29 AM archivist: or source anyway
05:29 AM XXCoder: yay! author of estlcam plan to make video for inlays :D
05:30 AM archivist: dont need no cam for inlay!
05:31 AM XXCoder: dont need no cam for inlay! = do need cam for inlay!
05:32 AM archivist: lazy bum, it is a craft handed down the centuries
05:33 AM XXCoder: yep I got no craftmanship in my bones lol
05:33 AM R2E4_bevins1: the logo in the source is worse than the one on the site
05:34 AM R2E4_bevins1: and its a gif.....yuk
05:34 AM archivist: the trick is trawl the mailing list logs back to its creation
05:35 AM XXCoder: R2E4_bevins1: https://upload.wikimedia.org/wikipedia/commons/3/35/Tux.svg
05:35 AM XXCoder: search term: linux mascot svg
05:35 AM archivist: but that is not our logo
05:35 AM R2E4_bevins1: thats not the logo
05:35 AM R2E4_bevins1: I get lost in the mailing list
05:36 AM XXCoder: ah missed cnc part
05:36 AM R2E4_bevins1: 5 years ago the rebranding?
05:36 AM archivist: I would change your search to linuxcnc mascot svg
05:39 AM XXCoder: no logo at wiki, lousy pictures
05:42 AM R2E4_bevins1: going to have to rastersoze it..... damn
05:42 AM XXCoder: I found a big one
05:43 AM XXCoder: hmm low quality nm
05:43 AM XXCoder: best bet is find best one and vectorize it
05:44 AM XXCoder: good thing simple images is easy to do
05:47 AM R2E4_bevins1: what was the name of the mascot? Chipper?
05:48 AM XXCoder: this is SOLE one I found full bodied linuxcnc mascot
05:48 AM XXCoder: http://fab.cba.mit.edu/classes/961.09/people/jonathan/img/chips2.png
05:48 AM XXCoder: source unknown
05:48 AM R2E4_bevins1: source too small....lol
05:48 AM XXCoder: thats not source
05:49 AM XXCoder: zi forgot how to do image search
05:49 AM XXCoder: ah found
05:51 AM XXCoder: wow. results is... scant,.
05:53 AM XXCoder: many of larger ones is bad edits of orginial tiny image
05:53 AM XXCoder: R2E4_bevins1: any luck?
05:53 AM R2E4_bevins1: no
05:53 AM XXCoder: wow what happened to orginial
05:54 AM R2E4_bevins1: cant even rasterize it, the image is too pixely....
05:54 AM R2E4_bevins1: I'll put a post in the forums and maybe someone will [pipe up.
05:54 AM XXCoder: let me know
05:56 AM archivist: R2E4_bevins, there is an unanswered request from 2010
05:56 AM archivist: on the forum
05:57 AM R2E4_bevins1: the one on the forum is too pixely....
05:57 AM R2E4_bevins1: too small, and when scale it it gets worse
05:57 AM XXCoder: its possible it has to be recreated
05:57 AM archivist: I do remember something on the mailing list
05:58 AM archivist: R2E4_bevins, https://forum.linuxcnc.org/38-general-linuxcnc-questions/2610-linux-emc-logo
05:59 AM R2E4_bevins1: lol, theres no respopnse to that thread....
05:59 AM archivist: and the name is close
05:59 AM R2E4_bevins1: I\ll re create it but thats about three hours of work
06:01 AM archivist: user mailing list [Emc-users] name of Linuxcnc mascot
06:02 AM archivist: was also mentioned in [Emc-developers] LinuxCNC as a "Brand" (Was Re: Licensing Questionaire)
06:03 AM R2E4_bevins1: any gueses on the font LinuxCNC?
06:04 AM archivist: from what I read, there is no control of any logo, you choose
06:04 AM XXCoder: arial black?
06:06 AM R2E4_bevins1: the greyscale gradien would be a problem for me. otherwise I can create it......
06:06 AM R2E4_bevins1: the endmill will be a bitch
06:06 AM XXCoder: its not too hard
06:06 AM archivist: gimp
06:06 AM XXCoder: nah injkscape
06:07 AM XXCoder: you control direction of gradient easil
06:07 AM archivist: solidworks!
06:07 AM R2E4_bevins1: I am doing the vectors now.
06:07 AM XXCoder: hard drive and magnets :P
06:07 AM archivist: you can control direction in gimp too
06:10 AM R2E4_bevins1: Arial Black.... BANG ON!!
06:10 AM XXCoder: yeah one of my favorite font
06:11 AM XXCoder: the "ily" part of recent engrave is arial black font
06:13 AM R2E4_bevins1: I hate it when you lose the toolbox in gimp. I can never find it to get it back
06:13 AM XXCoder: https://www.youtube.com/watch?v=8wk-qRfJQPM hah
06:13 AM XXCoder: R2E4_bevins1: "view" menu item?
06:15 AM R2E4_bevins1: nope
06:16 AM R2E4_bevins1: tools/new toolbox....... lol
06:16 AM R2E4_bevins1: Shouldnt that be in view?
06:16 AM XXCoder: Edit menu → Preferences → Window Management → and click the button for Reset Saved Window Positions to Default Values.
06:16 AM XXCoder: wonder how many toolboxes you have now lol
06:16 AM archivist: tools/hammer/nail
06:16 AM XXCoder: looking for better
06:16 AM XXCoder: "If the GIMP session is still open, restore the toolbox you just closed by going to Windows -> Recently Closed Docks, and it should be there in the list."
06:17 AM Loetmichel_: soo, as i lost my leatherman wave two weeks ago i ordered a new one. It was just delivered. Black one this time... Murphy says that the old one (18 years!) will reappear now ;-)
06:17 AM XXCoder: "To prevent this happening in future, you can uncheck the Save window positions on exit checkbox (same page), so the toolbox always reappears when you restart GIMP, no matter if you closed it earlier or not."
06:19 AM XXCoder: looked into "dockable windows" menu?
06:24 AM R2E4_bevins1: This is not going to be easy
06:28 AM XXCoder: maybe you can use that rare "mascot alone" picture to do that part
06:28 AM XXCoder: http://fab.cba.mit.edu/classes/961.09/people/jonathan/img/chips2.png
06:29 AM XXCoder: oh found name its chips
06:29 AM XXCoder: maybe this will help. LOL http://juve.ro/blog-files/photography/01289848744/IMG_0893.JPG
06:31 AM R2E4_bevins1: lol
06:31 AM nallar is now known as Ross
06:31 AM XXCoder: no luck with CHIPS
06:32 AM R2E4_bevins1: yeah, I was doing vectors, but this will have to be done in gimp if I do it that way but it looks easier
06:33 AM R2E4_bevins1: but it still wont be scalable.
06:33 AM XXCoder: found old one http://linuxcnc.org/docs/2.4/html/emc2-intro.png
06:33 AM XXCoder: got idea
06:33 AM XXCoder: make bigger one, then vectorize THAT one
06:34 AM XXCoder: pinterest is fucking image search virus
06:35 AM XXCoder: http://www.cnc-toolkit.com/chips.html fancy
06:35 AM XXCoder: funny theres more pictures of old one than new
06:35 AM XXCoder: that page alone has 3 unique images.
06:35 AM jthornton: http://www.rainnea.com/Tux-4.jpg
06:36 AM jthornton: I think that is the original tux for emc
06:36 AM XXCoder: orginial chips yeah
06:36 AM jthornton: tux not chips
06:36 AM XXCoder: but there is one and exactly one image of new chips
06:36 AM XXCoder: tux is linux mascot. chips is linuxcnc mascot
06:37 AM R2E4_bevins1: chips scales not bad in gimp
06:38 AM XXCoder: sadly this is THE biggest chips new version image http://fab.cba.mit.edu/classes/961.09/people/jonathan/img/chips2.png
06:38 AM jthornton: I think EMC before EMC2 called him tux-4 with a hammer and micrometer
06:39 AM R2E4_bevins1: 128X148
06:39 AM R2E4_bevins1: not good. I just scaled him up to 700X800, i think I can work with that to get a vector
06:39 AM XXCoder: maybe you can invent new one based on newer one with tool and release vector images
06:40 AM R2E4_bevins1: too bad theres no trace in gimp
06:40 AM XXCoder: inkscape has
06:40 AM XXCoder: and its pretty damn good
06:45 AM XXCoder: not too successful
06:45 AM XXCoder: but pretty close.
06:46 AM R2E4_bevins1: you have to scale it up before
06:50 AM MacGalempsy: JT have your drones arrived yet?
06:50 AM MacGalempsy: links to your buys?
06:52 AM XXCoder: gradients kill trace
06:57 AM R2E4_bevins1: yeah..... I got the best trace with Inkscape
06:57 AM R2E4_bevins1: May have to work with that.... but will have to redo each line
06:57 AM XXCoder: your pre-processing must be better than mine
06:57 AM XXCoder: I'm AWESOME on making images for kindle pw2 screensaver lol butlimited otherwise
06:58 AM R2E4_bevins1: I scaled it up in gimp first, but Aspire does a better job at the trace than Inkscape
06:59 AM R2E4_bevins1: I get the dxf from there and then have Inkscape do the colors
06:59 AM XXCoder: pretty decent?
07:06 AM R2E4_bevins1: I am tracing manually. Will take some work but will be better.
07:06 AM XXCoder: yea
07:06 AM R2E4_bevins1: Someone must have it though.
07:06 AM XXCoder: yeah
07:06 AM XXCoder: amazed only opne image!
07:14 AM XXCoder: once youre done, make vector aviliable, AND make HUGE picture somewhere to reverse engineer if vector is somehow gone
07:17 AM MacGalempsy: well im out pf here. laters
07:17 AM XXCoder: later
07:30 AM R2E4_bevins1: XXCoder: can you do the gradients?
07:30 AM XXCoder: sure though not today
07:30 AM R2E4_bevins1: Can you import dxf into Inkscape?
07:31 AM XXCoder: never had to but im pretty sure yeah
07:31 AM R2E4_bevins1: yeah it can
07:31 AM XXCoder: yep
07:32 AM R2E4_bevins1: I am doing a clean dxf, should be able to import into Inkscape to do the colors
07:40 AM XXCoder: yea
07:40 AM XXCoder: love this chgannel https://www.youtube.com/watch?v=uZGFTmK6Yk4
07:41 AM XXCoder: hes working under caveman limits but with modern knowledge
07:44 AM jym: XXCoder: And you're working under modern technology with caveman knowledge ;)
07:44 AM XXCoder: lol
07:46 AM XXCoder: going to bed, r2 talk about this more later
07:48 AM jym: XXCoder: ug ug ug
08:27 AM * JT-Shop hopes that 1/4 drop of hoppes #9 will keep the video card fan going for a while
09:38 AM Wolf_: hoppes #9 isnt lube...
09:47 AM gonzo_: notro solvent isn't it?
09:47 AM gonzo_: nitro
09:55 AM The_Ball: Picked up my new (old) mill this weekend, can't wait to start converting it, but house renovations are getting in the way :(
10:09 AM chopper79: computer buying time.... Need to decide on a PC to control my 7i76E
10:11 AM chopper79: Needs to be dual lan and as small as possible.
10:15 AM codepython777: does anyone have a nicer glue gun that they love?
10:15 AM DavenportGuy: chopper79: something like this? EKJNF9UM557POS
10:15 AM JesusAlos: Hi All
10:16 AM JesusAlos: I'm looking for a G-code command for scale and an other one for mirror.
10:17 AM JesusAlos: Does somebody know a G-code command for that?
10:17 AM JesusAlos: I don't find it in the documentation http://linuxcnc.org/docs/html/gcode.html
10:18 AM JesusAlos: and the most nearby topic where this page: https://code.google.com/archive/p/grecode/
10:19 AM chopper79: DavenportGuy: Might work, but I am not sure if the processor is suited. From what I have seen so far in previous talks is that the J1900 and the N3150 or the go to processors for the ethernet boards.
10:19 AM DavenportGuy: oh right, I was using this one with the 7i90
10:20 AM chopper79: This is the issue I am having as I am not a computer person for the most part and all these options available make the choice hard. I dislike spending 300 on a pc for it not to work properly with my hardware.
10:21 AM chopper79: Which is why it has taken me the last 2 months to get to the point to where I am ready to make a purchase.
10:21 AM chopper79: Trying to make sure it is 100% proper choice.
10:21 AM DavenportGuy: spring cleanup computers work great
10:21 AM DavenportGuy: :)
10:22 AM chopper79: I agree... They work well for the most part. This needs to be a repeatable item though.
10:23 AM chopper79: Since all the pc parts come from China anyway I am not opposed to purchasing direct from China.
10:23 AM DavenportGuy: ohh? you got a multirun project coming along?
10:23 AM chopper79: yes
10:23 AM DavenportGuy: do tell
10:32 AM JesusAlos: Can I use cutter compensation as scale factor?
10:32 AM JesusAlos: I'm not sure if is the same.
10:33 AM gregcnc: cutter comp is not a scaling code
10:35 AM gregcnc: while many controls have a gcode for directly scaling and mirroring Linuxcnc does not
10:36 AM gregcnc: however, this doens't mean you can't create code that isn't scalable
10:37 AM JesusAlos: Sorry
10:38 AM JesusAlos: I'm here now
10:38 AM IchGucksLive: hi
10:39 AM gregcnc: if you look at the "linuxcnc" code when you open axis you can get an idea of how it was scaled
10:39 AM chopper79: May have to do a Mini ITx board and just live with it. Hope this processor is not chnagning soon. https://www.newegg.com/Product/Product.aspx?Item=N82E16813135391&cm_re=j1900-_-13-135-391-_-Product
10:39 AM JesusAlos: hi
10:40 AM JesusAlos: About the scale I mean if there are a G-code command as for example G50 G51
10:41 AM JesusAlos: in linuxcnc
10:41 AM gregcnc: yes i know Fanuc has scaling and mirror
10:41 AM cradek: nope
10:41 AM JesusAlos: oh
10:41 AM JesusAlos: ok. Thank
10:41 AM cradek: what problem are you trying to solve?
10:42 AM skunkworks: chopper79, I think I am running the a j1900 on the matsuura. Gigabyte board
10:42 AM JesusAlos: I was looking for a gcode command for scale and an other one for mirroring
10:42 AM skunkworks: (it has dual nics so worked well for the 7i80
10:43 AM chopper79: Looks like they are ending product cycle for the J1900 in Q1, 2019. That is long enough for a new board to be found to work well.
10:44 AM IchGucksLive: JesusAlos: Hi there is a cool gcode shifter python that scales you the gcode as you want
10:44 AM chopper79: skunkworks: I would like to use the j1900 as it seems that users are having good experience with them.
10:44 AM JesusAlos: IchGucksLive: I see https://code.google.com/archive/p/grecode/ but is little complicate for use
10:45 AM IchGucksLive: you can also redxf you gcode
10:46 AM IchGucksLive: why is it complicate
10:46 AM JesusAlos: Because need to use the command line
10:47 AM IchGucksLive: you can put that command into a python GUI
10:47 AM JesusAlos: And the people who use the machine doesn't familiar with it
10:47 AM skunkworks: or x[100*#<scale>]Y[200*#<scale>]...
10:48 AM IchGucksLive: it is not the action of the CNC operator to scale a gcode
10:48 AM IchGucksLive: this comes from the office man
10:49 AM IchGucksLive: skunkworks: there is also a cool py that inputs load the ngc and outputs it with #111 SCALE
10:49 AM IchGucksLive: only xy
10:49 AM JesusAlos: A simple command like skunkworks says can be able
10:49 AM gregcnc: I always wondered what you'd use scale and mirror for, but it must have been practical before CAM
10:49 AM IchGucksLive: all is posible
10:50 AM JesusAlos: They don't need to have a CAM in the machine only for scale or mirroring with easy G-code commands
10:52 AM JesusAlos: IchGucksLive: Do you mean I can integrate it in the interface?ç
10:52 AM IchGucksLive: LCNC loads pythons
10:52 AM IchGucksLive: so load scale.py
10:52 AM IchGucksLive: load mirror.py
10:53 AM IchGucksLive: on coustom service at xhc-hb04 i load always ngc7000.ngc
10:54 AM IchGucksLive: so why not do that by button to reload a scaled ngc
10:55 AM IchGucksLive: http://linuxcnc.org/docs/html/man/man1/axis-remote.1.html
10:56 AM IchGucksLive: lets say you fire mdi M188 1.5
10:57 AM chopper79: Interesting... almost want to get one just to play with. http://www.ebay.com/itm/NESO-20-AIO-All-In-One-Touch-Intel-BayTrail-J1900-SoC-4GB-RAM-500GB-Storage-/132113145512?hash=item1ec28e9ea8:g:~U4AAOSwopRYf7jd
10:58 AM JesusAlos: IchGucksLive: I undestand your proposal. I need to study it for integrate.
10:58 AM JesusAlos: Thank
11:02 AM IchGucksLive: i need to go majot audition today lets see what hee needs in case CNC
11:03 AM IchGucksLive: Town Major
11:03 AM pcw_home: chopper79: https://www.newegg.com/Product/Product.aspx?Item=N82E16813157726
11:03 AM pcw_home: this one works well with our Ethernet cards (not sure if the old RTAI kernel with Wheezy would work though)
11:05 AM chopper79: looking it over now
11:06 AM pcw_home: the 4 core version would be a bit snappier
11:19 AM chopper79: pcw_home: The quad core is the N3150 or the J3455?
11:20 AM pcw_home: Yeah
11:22 AM pcw_home: also J4205 (I haven't tried that one yet)
11:32 AM chopper79: I am going to settle on the J3355B as it hits the price point needed will do the job properly.
11:39 AM pcw_home: I've had one (Asrock J3355) running linuxcnc for a month or so here without issue
11:39 AM pcw_home: Only possible complaint is that it doesn't have the best graphic performance
11:40 AM chopper79: pcw_home: Just to rule this out..... Will all in ones with a J1900 or simliar work fine or do they function as over grown laptops?
11:41 AM pcw_home: I dont know about all (I know the Gigabyte Brix J1900 mini PC works because I have one)
11:41 AM chopper79: Using Axis with some custom buttons so graphics shoul dnot be horrible I would think. I know when I was running gmoccapy things were very slow for me (graphically)
11:43 AM pcw_home: I'll have to try Mint on the J3355 (running Wheezy/Preempt-RT)
11:44 AM chopper79: https://www.newegg.com/Product/Product.aspx?Item=N82E16883101457&cm_re=intel_all_in_one-_-83-101-457-_-Product
11:44 AM chopper79: This is why I was asking about all in ones
11:46 AM chopper79: I always like the idea of the fewer boxes on the bench the better. Which pushes me towards the Gigabyte Brix style units also. Then I can mount them on back of the monitor
11:53 AM Wolf_: I have mint running on a J1900, https://www.newegg.com/Product/Product.aspx?Item=N82E16813157494
11:59 AM Wolf_: hmm, I should order the mesa stuff I need to run my servos while I actually have $$$
12:15 PM chopper79: Any reason I could not take a 5v+ leg from my pc power supply for the 7i76E? Keep in mind that the power supply is also running the pc at the same time.
12:17 PM archivist: which side of any optos is it
12:17 PM chopper79: Also at the same time take a 12v leg from he same power supply to run the field power?
12:17 PM chopper79: archivist: No follwoing you, please explain.
12:18 PM pcw_home: I would suggest running the 7I76e from an isolated supply
12:18 PM chopper79: ok
12:19 PM pcw_home: Either 12V or 24V at the control (you dont need 5V if you use the 7I76Es local 5V supply))
12:20 PM chopper79: The stepper drivers are running at 36v so there is one supply. Then I would need one for the 7i76e and a 3rd one for the PC
12:21 PM archivist: isolated supplies reduce ground loop risk
12:21 PM chopper79: working on making a single enclosure that has all electronics in it.
12:21 PM archivist: I often have isolated dc-dc in my control
12:21 PM jdh: pcw: do you sell boards to liburdi? the pc104 stuff looked like mesa cards
12:22 PM jdh: guess they all look pretty much the same
12:23 PM skunkworks__: chopper79, on the matsuura?
12:23 PM chopper79: No another project.
12:23 PM skunkworks__: You have a lot of enclosure space now... ;)
12:23 PM skunkworks__: ah :)
12:23 PM skunkworks__: any luck with the gear tooth sensors?
12:23 PM chopper79: The matsuura is open space wise.
12:24 PM chopper79: I ordered a different sensor and also agear.
12:25 PM chopper79: I found that the allegro sensors did not like the tooth geometry I used on the 1018 gear. Had trouble with it for some reaosn even though I was within the specs. I contacted allegro and they looked at my gear and told me that the spacing was to close to the min so that is why the issus were coming up.
12:26 PM chopper79: So the new parts arrive today.
12:27 PM chopper79: Also the testes allegro had me do worked better when I used an old cast iron gear over the 1018 material.... srange
12:28 PM chopper79: http://www.newark.com/honeywell/sng-qpla-000/speed-direction-sensor-4-wire/dp/52Y1832 ordered one of these to play with
12:31 PM chopper79: I have all 10 sensors left over still so I will use them on a future project.
12:31 PM chopper79: did not break anymore leads off...haha
12:31 PM IchGucksLive: hi
12:32 PM IchGucksLive: chopper79: one psu cabinett http://foengarage.de/4achs_elek.jpg
12:33 PM chopper79: I like it, but I need to put the motherboard in there for the PC, 4 drivers, 7i76e and some relays.
12:34 PM chopper79: then power supplies to run it all
12:35 PM IchGucksLive: this is the 7i76 cabinett http://heimwerkermarkt-tretter.de/schrank.jpg
12:36 PM chopper79: Should mention that it needs to fit on the desktop or simliar.
12:36 PM archivist: get a larger desk
12:36 PM * archivist ducks
12:36 PM IchGucksLive: chopper79: the newegg will fit to the 7i76e
12:36 PM IchGucksLive: plenty of relay room
12:36 PM chopper79: link?
12:37 PM IchGucksLive: i dont use this combo
12:38 PM chopper79: https://www.circuitspecialists.com/electronic-enclosure-em-06.html was going to model this up and see if I can fit it all in there. If so then I can mill the alum front and back panels with the cut outs I need.
12:38 PM IchGucksLive: you can also freek everything inside a BIG tower pc
12:39 PM IchGucksLive: like the fujitsu one you got 2 mounting sides with clamp direkt opener
12:40 PM GEFU: Guten Abend, vor einigen Tagen habe ich mir eine gebrauchte Portalfräse gekaugt, incl. PC mit Mach3. Nun möchte ich den Spindelmotor mit Mach3 ein und -ausschalten. Dafür habe mir ein Interface und ein SolidStateRelais gekauft. Das Interface versorge ich mit 12V. Nun meine Frage: woher nehme ich die Spannung (3 - 32 V) für das Relais? Vilel Grüße GEFU
12:40 PM IchGucksLive: SERVUS aus Zweibrücken
12:41 PM IchGucksLive: drück mal auf meine NICK
12:41 PM IchGucksLive: doppelt
12:46 PM chopper79: Heck with it I am buying the enclosure I linked to. Get it here and test fit everthing. Ordering the mini-itx MB and a PS as well.
12:47 PM chopper79: sometimes you just have to jump and see where you land
12:48 PM Tom_L: as long as you see land before you jump
12:49 PM chopper79: Its is a total of $250 for monitor, MB, enclsure, and my mother in laws parts. I will take the risk to get moving
12:49 PM chopper79: worse case is I use the parts for something else so no harm done as of now
01:14 PM IchGucksLive: oh there is a live beond broken bits
01:22 PM IchGucksLive: im off Gn8
01:24 PM CaptHindsight: https://www.crowdsupply.com/plugg-ee-labs/juicyboard heh, mini IO and drivers cards on a tiny backplane
01:36 PM chopper79: wicked cool http://www.hindtechnology.com/
01:37 PM chopper79: wish I was able to make soemthing like this for lcnc
01:39 PM CaptHindsight: lol the backstory
01:40 PM CaptHindsight: "The idea for this radical design came from a bad experience while making CNC machines. The PC based system was too complex to setup, further there were a lot of hardware and software compatibility issues.
01:40 PM CaptHindsight: The PC based system would crash and we realized that a strong hardware is required to support a non PC based software that is specially designed to be a CNC controller and nothing more than that. "
01:41 PM chopper79: lol..yeah I did not pay attention to that and focused on the dream of having a unit like this but with lcnc on it
01:42 PM DavenportGuy: His biggest selling point is basically that he couldnt get a pc to work
01:42 PM chopper79: which is odd as if you could nto get a pc to work then how to you make this
01:42 PM CaptHindsight: chopper79: you have to make money to stay in business
01:43 PM CaptHindsight: how much profit is there in putting LCNC into a small box?
01:44 PM chopper79: I do nto sell lcnc.... it is offered free as a control software. I make money on other parts of the system.
01:44 PM CaptHindsight: profit in LCNC controller then?
01:47 PM CaptHindsight: as many will agree with there, if they make some income from LCNC it's with systems, support and add-ons etc etc
01:47 PM DavenportGuy: I suspect the profit is rather high really, if someone could get it to be fully functional with embedded web, print, etc, it would replace most PLCS and other controls. probably
01:47 PM CaptHindsight: automation technologies sells mach3 systems in a box
01:48 PM chopper79: I agree... full pc functionality with lcnc in a small package like that would be huge for me
01:48 PM DavenportGuy: instead of attaching a pc to a PLC unit and talking to it, you just wifi in and everything you need is already embedded, or just add a kbd and mouse, etc
01:49 PM chopper79: I guess that is the route that beagle bone and machinekit are moving.
01:49 PM chopper79: A single unit with a cape for all your i/o
01:49 PM CaptHindsight: Hind sells the controller to work with their motor drives
01:50 PM chopper79: use any drive with step and direction inouts
01:50 PM chopper79: inputs
01:51 PM CaptHindsight: steppers make it easier
01:51 PM chopper79: Would be a dream come true if I could marry the awesomeness of Mesa product with a embedded OS in one package.
01:51 PM CaptHindsight: chopper79: if you want 1K or more systems I'll put it together for you
01:52 PM CaptHindsight: or find me another 999 buyers :)
01:52 PM chopper79: Take the 7i77 and the 7i76 and put the embedded OS on the board... heaven
01:52 PM DavenportGuy: 998
01:52 PM DavenportGuy: ill take 4
01:53 PM chopper79: I woul dbuy multiples
01:53 PM CaptHindsight: Hinds 5-axis mill controller is $575
01:53 PM chopper79: Depending on the price and all I would be interested in 500 units
01:54 PM chopper79: sorry 50 units
01:54 PM chopper79: fat thumb
01:55 PM chopper79: to start with...
01:57 PM CaptHindsight: Rpi3 + FPGA
01:58 PM chopper79: Need graphics to be more solid and "real ethernet" port.
01:58 PM CaptHindsight: spend a few weeks ironing out the gpu issues
01:58 PM chopper79: Based on the complaints I have seen
01:58 PM CaptHindsight: and kernel
01:59 PM CaptHindsight: yeah well you have to put in the time to work out the toolchains and drivers
01:59 PM CaptHindsight: once you do that everyone wants your working source
02:00 PM CaptHindsight: since everyone else just posts the crap that boots
02:00 PM CaptHindsight: or was hastily hacked together
02:00 PM chopper79: Maybe it is time for me to buy a Rpi, BB, cubie to have here as a spare time project so see what I can mess up. Which is pretty much gonna happen since I am not a coder or a big PC guy
02:00 PM CaptHindsight: the hardware is easy
02:01 PM CaptHindsight: if the box can be a bit larger, then use a mini-itx x86
02:02 PM chopper79: hmm... adding those boards to my list of things to buy today.
02:03 PM CaptHindsight: the only reason I mention the RPi3 is the open source GPU drivers and libs
02:03 PM chopper79: Get to remove one of those boards as I have a cubbie 2 here already
02:04 PM CaptHindsight: the problem with cubie/allwinner is the mali gpu
02:04 PM CaptHindsight: no source
02:04 PM CaptHindsight: so you're stuck with whatever kernel they decided to post
02:04 PM chopper79: Could one make their own?
02:05 PM CaptHindsight: we had pretty decent software rendering on one of the allwinners a few years ago
02:05 PM CaptHindsight: own gpu?
02:05 PM t12: if youre into pain and suffering
02:05 PM FinboySlick: chopper79: Unlikely. If they went like nVidia, you may be able to load the gpu driver on your build of the same kernel version.
02:06 PM FinboySlick: But if they modded the kernel directly to get their driver to work (and their code isn't confined to modules), you're SOL.
02:06 PM chopper79: I am green on this stuff so please understand......
02:06 PM CaptHindsight: we looked at that as well, lots of pain
02:07 PM FinboySlick: chopper79: Basically, you can build your own kernel, but it won't contain the changes they made to get their GPU to work.
02:07 PM CaptHindsight: I don't think that the world would end if mali had open source
02:08 PM CaptHindsight: but it's a little bit of profit and power that would have to be let go of by the holders
02:08 PM chopper79: mali??
02:08 PM FinboySlick: CaptHindsight: Honestly, I don't see how the closed source benefits them at all.
02:09 PM FinboySlick: If people don't need to mess around with proprietary code to use your hardware, they're more likely to buy it.
02:10 PM CaptHindsight: makes them feel better
02:10 PM CaptHindsight: ask any tyrant or many managers
02:11 PM CaptHindsight: why do people file patents just to block others and never make the product?
02:11 PM CaptHindsight: control
02:11 PM CaptHindsight: if they can't win then make sure nobody else can either
02:11 PM t12: for gpu its more complicated than that
02:12 PM t12: it exposes alot of internal arch
02:12 PM t12: skeletons in closets
02:12 PM CaptHindsight: yeah
02:12 PM t12: patches to silicon revisions
02:12 PM FinboySlick: ... patent infringements ;)
02:12 PM t12: opens the door to every oss person bugging you small dev team about their ugly code
02:13 PM FinboySlick: Has that project to build a proper open source gpu ever progressed?
02:13 PM CaptHindsight: look at it through the eyes of a small selfish child
02:13 PM CaptHindsight: what would they want or do?
02:14 PM FinboySlick: CaptHindsight: Hehe, I do that for every human.
02:14 PM CaptHindsight: me me me answers most of these questions
02:14 PM FinboySlick: That way if there is a surprise, it's a pleasant one.
02:15 PM FinboySlick: On a positive note though, most humans are better than we give them credit for.
02:16 PM CaptHindsight: me have to go :)
02:16 PM chopper79: later
02:28 PM andypugh: How to configure the network in Debian: First download this package. Err…..
02:38 PM skunkworks__: andypugh, I am with you. I want a 3d printer - just don't have a really good reason yet.
02:39 PM skunkworks__: (well - you have a good reason for making patterns..)
02:40 PM CaptHindsight: andypugh: whats the largest pattern you'd need to print?
02:40 PM andypugh: Probably a cylinfer block :-)
02:40 PM CaptHindsight: sand cast?
02:41 PM andypugh: yes
02:42 PM CaptHindsight: I'd make an inkjet printer using micronozzles
02:44 PM CaptHindsight: Cartesian system with http://www.rea-jet.co.za/34-thickbox_default/valvejet-print-heads.jpg
02:44 PM skunkworks__: I think andy wants something he doesn't have to R&D the hell out of ;)
02:45 PM CaptHindsight: he's no dope, the valves are just on/off
02:45 PM CaptHindsight: not a piezo printhead
02:47 PM CaptHindsight: http://abmmarking.com/inkjet_valves.html look for the chinese clones
02:51 PM CaptHindsight: http://www.theleeco.com/electro-fluidic-systems/solenoid-valves/vhs/vhs-series-solenoid-valves.cfm easy to drive
02:54 PM CaptHindsight: the trick is having a heat set binder in the sand, then you just need to print the surfaces with a UV cured resin
02:54 PM CaptHindsight: after printing you bake the pattern to set the core of the sand
02:56 PM CaptHindsight: so the UV resin forms the hard outer shell so you can move the sand pattern from the printer to an oven, then you bake the pattern so that it's hard all the way through
02:58 PM {HD}: Whoever looked at this with me weeks ago I have the anwser since, it is now in hand. Its a 382L chip... http://www.ebay.com/itm/141973277356?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
03:14 PM CaptHindsight: just noticed I said pattern when I meant mold/mould
03:16 PM andypugh: printing moulds is cool, unless you want two of the part.
03:16 PM andypugh: And can guarantee that the foundry will get it right.
03:16 PM andypugh: And know how to set up gates and risers.
03:17 PM andypugh: With a wooden pattern the foundry decides how to pour it, and if it goes wrong, he tries again.
03:22 PM CaptHindsight: andypugh: I print patterns with SLA
03:24 PM CaptHindsight: SLA is 100x faster than FDM but costs a bit more
03:24 PM CaptHindsight: somebody just started selling an LCD resin printer for $500
03:25 PM CaptHindsight: forget the screen size
03:26 PM CaptHindsight: https://www.3dprintersbay.com/wanhao-duplicator-7-sla-3d-printer
03:27 PM CaptHindsight: nevermind 120 x 68mm is too small a print area
03:30 PM gregcnc: that would be almost perfect for my castings
03:30 PM CaptHindsight: I guess i should make one that uses a 40" 4k lcd for engine blocks
03:37 PM gregcnc: The film "FEP" is that a special material?
03:40 PM CaptHindsight: clear teflon (ptfe) coated film
03:41 PM CaptHindsight: https://en.wikipedia.org/wiki/Fluorinated_ethylene_propylene
03:42 PM CaptHindsight: the printer projects up through the bottom of the resin vat
03:42 PM CaptHindsight: the bottom of the vat is the FEP film
03:42 PM CaptHindsight: it's ok as long as you don't print too fast and start to melt the film
03:43 PM AlSmt: anyone know of a bug Scaling ttt g-code
03:43 PM CaptHindsight: the radcure polymerization is exothermic
03:45 PM AlSmt: I get Circular move on line 588 would exceed joint 0's negative limit & there is no way I'm out of travel
03:46 PM AlSmt: version 2.7.8
03:52 PM AlSmt: the program runs in sim @ that scale no trouble and only a portion of a letter that gives trouble on real machine
03:55 PM AlSmt: thanks anyway
04:25 PM Deejay: gn8
05:22 PM Crom: this was wierd... Computer would not boot until I unhooked all usb and the parallel cable
05:34 PM Tom_L: i have one that does that
05:34 PM Tom_L: USB at least
05:51 PM Crom_: Looks like it's gonna be $50 to fix mum's iPad digitizer.
05:53 PM Crom_: Mm my tea... Time to turn the kettle on
05:54 PM Crom_: My tea cup is a 14oz Keep Calm Carry On Union Jack mug
05:58 PM Crom_: Hmmm Friday is payday, 1st is on a Saturday so I should have money Friday
05:58 PM Tom_L: here on Friday, gone on Saturday
05:59 PM Crom_: We'll be on the road taking kidlette back to college
06:01 PM Crom_: So I can fill up Friday but I should make her fill it up... Plead I'm broke still
06:03 PM Crom_: And I have a tracking number for my motors
06:04 PM Crom_: I can wave as they go past me heading for Ohio
06:07 PM {HD}: Crom_: Why are they going to Ohio?
06:07 PM os1r1s: CaptHindsight Not all SLA is faster than FDM. It depends on a lot of factors.
06:09 PM Crom_: That's where my buddy lives... He then ships them to me. PayPal to me the money would have worked better
06:10 PM {HD}: Crom_: So, it is cheaper to ship to Ohio then to you? or your buddy paid for them and just did not ship them to you?
06:11 PM Crom_: 2nd option... Some sellers won't drop ship
06:12 PM Tom_L: where are you? canada?
06:12 PM CaptHindsight: os1r1s: well yeah I could slow the laser scan rate down or use really slow resin with a DLP/LCD
06:13 PM CaptHindsight: or print 1um layers, etc etc
06:13 PM Crom_: Peoples Republic of Kalifornistani
06:14 PM Tom_L: so why not just ship to you?
06:14 PM Tom_L: buying illegal to Ca stuff...
06:15 PM os1r1s: CaptHindsight SLA is pretty fun. One of the guys has a pretty cool one at a conference I co-run this past weekend.
06:17 PM Crom_: Heh... Yeah highly illegal integrated Closed Loop Stepper motor + driver
06:17 PM Crom_: Seller will only ship to PayPal address
06:18 PM CaptHindsight: that is a Paypal issues
06:18 PM CaptHindsight: Paypal won't protect the seller if you ship to a different address
06:19 PM CaptHindsight: kind of a pain if you have a business customer and they use their personal Paypal account
06:19 PM roycroft: it takes like 1 minute to log into paypal and add another address
06:19 PM CaptHindsight: "can you send it to my office vs home?"
06:19 PM CaptHindsight: roycroft: yeah but most don't
06:19 PM roycroft: the answer is "can do, but won't
06:20 PM roycroft: "
06:20 PM * roycroft says in his best john cleese voice
06:20 PM CaptHindsight: I haven't been burned but I now stick to the "only ships to Paypal address"
06:20 PM CaptHindsight: hehe
06:21 PM Crom_: Good idea!
06:21 PM CaptHindsight: I've had people not pay UPS for shipments after asking if we can use their account only to have UPS bill us 6 months later for their non payment
06:22 PM CaptHindsight: so that is only best done when the customer sends you a prepaid UPS or FEDEX label
06:22 PM CaptHindsight: no more use our account number
06:23 PM Crom_: Looking at the manual for the steppers, dir must lead dir by 6us and pulse width and space not less than 2.5us
06:23 PM Crom_: Need to see if there is a linuxcnc setting for dir leading step time
06:24 PM andypugh: Crom: There is
06:24 PM Crom_: In HAL/
06:24 PM Crom_: ?
06:24 PM CaptHindsight: andypugh: how many days will a FDM printer take to make your patterns?
06:25 PM andypugh: CaptHindsight: A lot of this is just a displacement activity from hacking up the big block of (used) Sikablock 950 that I liberated from work
06:25 PM CaptHindsight: andypugh: do you want patterns that are reusable?
06:26 PM andypugh: This evening I hacked off a block 130 x 190 x 220, largely with a hand saw.
06:26 PM CaptHindsight: yeah, saw your discussion on the ML
06:28 PM Crom_: Ahhh direction setup in nano seconds eeeshz 60000 and step needs to be 2500 on both
06:28 PM CaptHindsight: I have thought about making an urethane foam printer since the expansion is determinable
06:29 PM Crom_: Oh no it's only 6000
06:29 PM CaptHindsight: https://www.youtube.com/watch?v=q_LEd-rUfuE
06:29 PM Crom_: Think my 1000 1000 2000 2000 is too low right now
06:30 PM CaptHindsight: andypugh: maybe this https://youtu.be/4MNmtJQy_bM?t=1m9s
06:31 PM CaptHindsight: only with a bit more finesse
06:32 PM andypugh: Spidecam, neat idea.
06:44 PM CaptHindsight: andypugh: what gets me is all that busywork going on in reprap and hardly anything useful has come of it
06:44 PM CaptHindsight: no foam printer, no large nozzle extruders, no combo FDM and SLA etc etc
06:44 PM CaptHindsight: they just copy off of each other
06:45 PM CaptHindsight: you have a real application and there's nothing right off the shelf for it
06:49 PM malcom2073: CaptHindsight: You've seen the 1.6mm nozzle?
06:50 PM malcom2073: I know a guy running it, works pretty well for larger prints
06:52 PM CaptHindsight: I need a 3mm
06:52 PM Crom_: James Bruton is running the 1.2 mm nozzle on hi lulzbot Taz
06:52 PM CaptHindsight: 3mm that uses pellets
06:52 PM Crom_: S/ hi / his /
06:53 PM CaptHindsight: https://www.youtube.com/watch?v=64XESsTfv_4 similar applications
06:54 PM Crom_: That would be a screw extruder of some discription
06:54 PM CaptHindsight: Crom_: why do I have to make it?
06:55 PM CaptHindsight: I can buy a zillion crappy nozzles that don't work well all <1mm
06:55 PM CaptHindsight: nozzles/extruders
06:55 PM Crom_: I saw something about a screw extruder 3D printer...
06:57 PM Crom_: Fudge linuxcnc machine locked up grrrrrr
06:58 PM Crom_: Gonna let it sit for a bit and see if it decides to come back to life
07:00 PM CaptHindsight: Crom_: http://www.titan3drobotics.com/pellet-extrusion-3d-printing-on-the-atlas/ was it this??
07:02 PM CaptHindsight: andypugh: here's a block done in FDM in 33 hours https://i0.wp.com/dev.titan3drobotics.com/wp-content/uploads/2016/07/engine-block-edit.jpg
07:03 PM Crom_: Looks familiar
07:06 PM Crom_: But I don't thin it's exactly that one I saw
07:10 PM Crom_: Rich rap Guy's pellet extruder
07:20 PM Crom_: He was using a deWalt auger bit 1/4 ground off a bit and it went down into a j head with the pe tube removed
07:24 PM CaptHindsight: Crom_: i saw a few ghetto pellet extruder builds. Where is my pro model?

07:29 PM CaptHindsight: but nothing ready for industry
07:30 PM Crom_: Had to adjust tension on sewing machine... Wife ran off with bobbin... Take up spring had 1/16" travel, now has 5/16" much better looking stitches
07:30 PM malcom2073: CaptHindsight: Why isn't the industry using such things?
07:31 PM CaptHindsight: ok, you are set up to meet with Nike and you walk in with this model https://www.youtube.com/watch?v=y9HCBvhvzwc
07:31 PM CaptHindsight: malcom2073: I and others have to build it
07:32 PM malcom2073: CaptHindsight: So you're asking why nobody else has released their designs??
07:32 PM malcom2073: Too many ?'s there
07:32 PM CaptHindsight: there either the old patent holders with glacial speed equipment for protos or
07:32 PM CaptHindsight: this crap
07:33 PM CaptHindsight: malcom2073: I'd like to buy a pellet extruder with a ~3mm nozzle
07:34 PM malcom2073: CaptHindsight: Right, but if you've built that sort of thing, maybe others have the same reasoning as you have for not releasing the designs for others to iterate on?
07:34 PM CaptHindsight: that's not a 8th grade science project
07:34 PM CaptHindsight: I don't want the design. I'll buy it if it works
07:34 PM malcom2073: I've seen a couple people go through it, and wind up finding out that it's more hassle than it's worth to save the little amount of money by using pellets vs filament (price vs time vs qty of stuff printed)
07:35 PM malcom2073: Or, they make a filament extruder
07:35 PM CaptHindsight: pellets are ~$1/lb
07:35 PM CaptHindsight: what filament is close to that?
07:35 PM malcom2073: The last part of my statement is key
07:35 PM malcom2073: qty of stuff printed
07:36 PM malcom2073: If you're only printing a lb or two a week, a pellet printer would only save you $20. If you're printing 500lbs a week on the other hand..... but who does that in the hobby world?
07:37 PM malcom2073: Why not design it yourself?
07:37 PM malcom2073: Maybe there is a market for it
07:37 PM CaptHindsight: I see you missed the first part of the discussion
07:38 PM CaptHindsight: how about we talk about baskets now
07:38 PM malcom2073: Heh.
07:38 PM malcom2073: Point taken.
07:38 PM Crom_: Delta wasp has up to a 10mm nozzle
07:39 PM Crom_: But I don't see a pellet feed
07:40 PM Crom_: Oh there it is... Still a gravity feed jam fest
07:41 PM Crom_: The atlas looked like it had a blow in pellet feed
07:41 PM Crom_: Aka air slurry feed
07:44 PM Crom_: CaptHindsight: Erectorbot.com

07:47 PM CaptHindsight: smell the quality http://www.erectorbot.com/store/images/ext2.jpg
07:48 PM Crom_: Anza.... That's up in dem dar hills-- small hill town about 30 miles from me
07:48 PM Crom_: Definitely not industrial
07:59 PM Crom_: $2800 for the pellet extruder
08:02 PM Crom_: $46435 for a 20x7x6' 3D printer
08:04 PM CaptHindsight: Crom_: yeah I should post something similar to see what bites
08:04 PM Crom_: Though it wouldn't be that hard to build a heated room around it to prevent warping and cut down on heat bed costs. I'd build a 12" thick walled and ceilinged room around it to trap all the build heat. I'd insulate the floor as well...
08:05 PM CaptHindsight: belt driven t-slot gantry
08:05 PM Crom_: Looks like it's basically a Marlin Arduino mega run machine
08:05 PM CaptHindsight: I'd go all out and use LCNC :)
08:05 PM Crom_: Extruder needs to be bigger though... Like the wasp one
08:06 PM CaptHindsight: I recall seeing a decnt pellet extruder where the extruder was stationary and the bed moved
08:06 PM Crom_: Love the bragging about TIG welded gantry
08:07 PM Crom_: I like the erectorbot idea...
08:08 PM CaptHindsight: reminds me of erector sets vs industrial automation
08:09 PM Crom_: Z is lead screw....
08:09 PM CaptHindsight: I think Cincinnati built a large gantry printer for Oak Ridge Labs
08:10 PM CaptHindsight: http://www.e-ci.com/baam/
08:10 PM Crom_: Not one encoder in sight... So error checking is non existent
08:11 PM CaptHindsight: designed by Klosenoff and Goodenoff
08:12 PM Crom_: With error routines by Justin Case?
08:12 PM CaptHindsight: https://static1.squarespace.com/static/549484f0e4b080be60b6baf1/54c01f45e4b0ed7b17d6c8d9/56533b56e4b0991ab31cf148/1448295262192/DSC03273.JPG?format=1000w
08:12 PM CaptHindsight: looks like pellets
08:13 PM CaptHindsight: and since it's made by Cincinnati the extruder can be yours for only $500K (just a guess)
08:13 PM Crom_: Looks? Definitely pellets
08:14 PM CaptHindsight: https://twitter.com/i/web/status/846806423715631108
08:14 PM CaptHindsight: https://www.engadget.com/2017/03/24/under-armour-3d-printing-architech-futurist/
08:14 PM CaptHindsight: looks like the shoe and underthing co's are trying the tech
08:16 PM CaptHindsight: https://pbs.twimg.com/media/C7jA3N7XQAAxE--.jpg:large better pic of the extruder
08:20 PM Crom_: Z is a linear actuator.... erector and BAAM are similar in concept.. the BAAM extruder looks closer to the Atlas one
08:24 PM MacGalempsy: evening folks
08:27 PM gregcnc: so that Wanhao D7 is just a Z axis with a 9" screen? does it actually process anything?
08:35 PM {HD}: is nethack.org down for anyone else or is it my vpn?
08:41 PM gregcnc: not 9" 5.4"
08:46 PM jdh: {HD}: http://downforeveryoneorjustme.com/nethack.org
08:48 PM {HD}: jdh: =( its just me =(
09:14 PM Crom_: AHHH BAAM has a Z table
09:15 PM CaptHindsight: gregcnc: yes Z with LCD
09:16 PM CaptHindsight: gregcnc: it projects and image to polymerize the resin at the bottom of the vat, then the image is off/dark, the build platform moves up releasing the polymerized resin from the bottom of the vat...
09:17 PM CaptHindsight: and allows the resin to flow under the layer just printed/exposed
09:17 PM CaptHindsight: the build platform moves back down to whatever layer thickness is set and the next layer is projected
09:18 PM Crom_: Looks to me the gantry on the BAAM is total overkill, Looks like the need to put a 5axis spindle on the other side of the gantry to run a ball end mill for clean up. That would take a lot of the finishing time off. Looking at the F22 Raptop... Looks like they sanded at least a 1/4 of material off
09:18 PM CaptHindsight: and it repeats these steps until the part is complete in the Z
09:19 PM CaptHindsight: Crom_: tax dollars, oak ridge labs
09:19 PM Crom_: True...
09:19 PM CaptHindsight: they certainly weren't just going to sell them what was just adequate
09:20 PM CaptHindsight: how big is this budget of yours was probably the question
09:20 PM Crom_: True that
09:24 PM Crom_: With one nozzle, going beyond a certain build volume is crazy. Ganged heads only really work for repetition. 2 gantries each with an extruder would probably up production at least to 190% that of one head.
09:30 PM Crom_: Giving the extruder heads a 3" Z could probably really speed this up a bit more.two heads working on one part. One head working on a really large part Andy the other doing a bunch of little parts, you could get up to a 6" difference in work height before you would get a slow down.
09:49 PM MacGalempsy: this storm is kinda scaring me
09:49 PM MacGalempsy: its raining sideways and we are in a trailer!
09:51 PM {HD}: MacGalempsy: Turn the weather radio on. Make sure there is no tornado coming.
09:52 PM MacGalempsy: if you look at the weather channel we are about an hour west of okc
09:52 PM MacGalempsy: holy shit we have circulation
09:53 PM {HD}: circulation? like funnel cloud?
09:53 PM roycroft: hide under the lathe!
09:54 PM MacGalempsy: the radar shows it in the field next to us
09:54 PM {HD}: MacGalempsy: Looking at the radar now...its RED
09:56 PM MacGalempsy: yeah. we are watching it pretty closely. we are at rd2610 and rd840 sw of Watonga, OK
09:57 PM roycroft: do you have a storm cellar/shelter?
09:57 PM MacGalempsy: yeah there is a double bunker installed on the location
09:57 PM roycroft: that's good
09:58 PM MacGalempsy: uploading a pic
09:58 PM roycroft: no working browser on this machine, but others may benefit
09:58 PM roycroft: if you need to bug out, bug out, and stop uploading pictures :)
09:58 PM MacGalempsy: https://flic.kr/p/S5vA1s
09:59 PM MacGalempsy: they havent even sounded the rig horn yet.
10:00 PM CaptHindsight: i had one go by me once when I was machining
10:00 PM CaptHindsight: the place just founded too noisy so I shut down the mill but the vibration was still there
10:00 PM CaptHindsight: founded/sounded
10:01 PM CaptHindsight: it sounded like a train going by
10:01 PM MacGalempsy: 98mph winds in El Reno
10:01 PM CaptHindsight: i opened the door and the green rain was going sideways
10:01 PM CaptHindsight: instantly soaked
10:02 PM CaptHindsight: ends up it passed by in the next field over
10:08 PM MacGalempsy: the door here is on the lea side
10:12 PM {HD}: MacGalempsy: What is that a picture of?
10:12 PM {HD}: where are you?
10:13 PM MacGalempsy: thats the drilling rig
10:13 PM {HD}: Oh, your at work?
10:13 PM MacGalempsy: yeah. ive been out here 2 weeks already
10:34 PM {HD}: are you still alive?
10:36 PM roycroft: looks like he just lost power
10:55 PM Crom_: iPad's suck at multitasking
10:56 PM Crom_: And I found some more dead spots
10:59 PM Crom: oh shit! Or lost signal because of lighting
11:00 PM Crom: digital phones lose connections near twisters... Analog phones kept signal alot better
11:02 PM Crom_: Time to check lcnc machine
11:05 PM Crom: time to let iPad charge
11:08 PM MacGalempsy: Crom where are you,
11:08 PM MacGalempsy: ?
11:21 PM Crom: People Republic of Kalifornistani, So Cal region
11:21 PM Crom: 2miles north of san diego on I-15
11:21 PM Crom: san diego county
11:22 PM Crom: nope had to power cycle the lcnc machine... but didn't have to unplug the parallel port
11:25 PM Crom: kewl... my wifes hair is starting to grown again after chemo, and the new hair is almost blonde right now
11:26 PM Crom: MacGalempsy, old boss and I were planning a storm chaser trip about 11 years ago
11:27 PM MacGalempsy: they had 3 die tonight in texas
11:27 PM MacGalempsy: i hate storms!
11:52 PM Crom: Gotta go get ready for a funeral tomorrow
11:53 PM Crom: Korean War Veteran, Merchant marine, neighbor
