12:02 AM Wolf_: good stuff, out of my budget range lol
12:08 AM SpeedEvil: yeah - sucks watching a video, and seeing the awesome performance, and then noticing behind the operator a LASER the size of an SUV costing more than the average house.
12:08 AM XXCoder: laser size of suv? jeez
12:09 AM SpeedEvil: https://www.youtube.com/watch?v=E3YCACZQ72Q
12:09 AM SpeedEvil: Hand-operated laser cutting for nuclear decommissioning
12:13 AM XXCoder: hey guy has laser weapon! too bad its not portable ;)
12:14 AM XXCoder: just curious why laser
12:14 AM XXCoder: why not saw or something
12:15 AM XXCoder: table itself is under decomission too
12:15 AM CaptHindsight: https://youtu.be/mX9L0wGlE2w?list=PLA1A8445FB486474F why I don't share much laser howto info
12:16 AM Wolf_: lol
12:17 AM Wolf_: I won’t be doing anything like that
12:17 AM XXCoder: I guess laser is better as it wont get radioactive
12:17 AM XXCoder: unlike say saw which would be covered in radioactive metal
12:18 AM Wolf_: I’m also wondering if I should go with a 80w laser vs the 100…
12:18 AM XXCoder: highly advanced use, capt lol
12:20 AM jym: Wolf_: material?
12:21 AM Wolf_: probably 1/2” ply max
12:21 AM jym: Wolf_: YOu probably want more like 150W-200W
12:22 AM jym: Wolf_: 1/2 wood, no probelm, but plywood, you need the added power
12:23 AM jym: resin/glues are a bitch
12:24 AM XXCoder: can lower watt do same but with repeted passes>?
12:25 AM jym: more like slower speed, REAL slow 1-2 ipm slow
12:25 AM jym: 1-3 IPM
12:25 AM XXCoder: isnt slower = more heat = fire?
12:25 AM jym: more penitration
12:26 AM jym: also air assist
12:26 AM Wolf_: air assist is a given
12:26 AM Wolf_: and a good extraction design
12:28 AM jym: Wolf_: 90W should work, just plan on it being slow
12:28 AM jym: err 80W
12:29 AM Wolf_: guess 100w it is lol
12:30 AM jym: are you getting the normal or special tube?
12:30 AM Wolf_: http://www.lightobject.com/High-Quality-RECI-100W-W4-CO2-Sealed-Laser-Tube-10000hrs-P119.aspx?ItemId=1282998 is what I was looking at
12:30 AM Wolf_: still trying to see who else sells them tho
12:31 AM jym: YEah, the RECI tube, I couldn't rememer the name
12:33 AM Wolf_: now if I could find a damn data sheet on the laser PSU…
12:34 AM jym: http://www.recilaser.com/en/index.htm
12:35 AM Wolf_: lol derp why didn’t i think of that
12:37 AM XXCoder: oh yeah, remembered I wanted to ask this question
12:38 AM XXCoder: I was talking about isolating signal wires from inference
12:38 AM XXCoder: I know adding metal covering would help but I knew it would need to be connected, but would PSU ground do it?
12:38 AM Wolf_: shielding is grounded one end only
12:41 AM XXCoder: yah what i thought. thanks
12:41 AM XXCoder: though I wonder why must one end alone
12:41 AM Wolf_: its pulling the RF to gnd
12:45 AM XXCoder: and both ended connection would mean it would fail to pull rf to ground?
12:50 AM archivist: no it then becomes a coil not just a shield
12:51 AM archivist: and a series conductor in a ground loop
12:52 AM XXCoder: interesting
01:19 AM Wolf_: wonder how good the EFR tubes are https://www.aliexpress.com/store/product/EFR-laser-tube-100w-laser-power-box-100w-efr-glass-tube-100w-100w-laser-power-supply/926078_32579482070.html?spm=2114.12010612.0.0.4WhVjq
01:19 AM XXCoder: remember it's 100w chinese watts
01:19 AM XXCoder: so.. 80w?
01:19 AM Wolf_: lol
01:20 AM XXCoder: 600 bucks
01:20 AM XXCoder: I saw website where guy made his own co2 laser tube
01:20 AM XXCoder: used ovc pipes and glass tube
01:20 AM XXCoder: unknown watt rating though
01:21 AM Wolf_: oddly the output wattage comes from current + tube length
01:21 AM Wolf_: and cooling
01:21 AM XXCoder: the homebrew tube I saw was quite long
01:21 AM XXCoder: though current might not be that high
01:22 AM XXCoder: https://hackaday.io/project/1023-low-cost-co2-laser-build
01:22 AM XXCoder: found it.
01:22 AM Wolf_: the 100w are 1400mm running at 28mA on the return side and 22kv
01:23 AM XXCoder: last update 2014 sadly
01:23 AM Wolf_: hmm, I have a source for lab glassware, and I have nitrogen and co2 at my shop
01:23 AM Wolf_: and a neon psu lol
01:26 AM XXCoder: I dont know if guy ever menioned watt rating of that homebrew.
01:32 AM Deejay: moin
01:36 AM roycroft: my homebrew is measured in abv, not watts
01:44 AM Wolf_: abv?
01:55 AM MacGalempsy: alcohol by volume?
01:56 AM XXCoder: acetone butune varance?
02:01 AM MacGalempsy: anyone watching Woodley Thompson tomorrow night?
02:01 AM XXCoder: dont use tv much
02:03 AM MacGalempsy: now that its free dish in the command center, its on all the time
02:04 AM MacGalempsy: its like cartoons, fights and star trek
02:05 AM XXCoder: fancy. I guess if im onsite for week I'd resort to tv evenually.
02:05 AM XXCoder: if its captioned
02:05 AM XXCoder: playing guess the dialog is very old and very boring game
02:06 AM MacGalempsy: heh. no choice on sound, just low and high
02:06 AM MacGalempsy: it helps drone out the generators
02:06 AM Wolf_: well, this doesn’t look to bad https://www.aliexpress.com/item/RECI-W4-S4-100-130W-laser-tube-for-CO2-laser-machine-with-DY13-power-supply/32792288197.html I wonder if the listing is correct lol
02:07 AM XXCoder: heh wouldnt care how loud or not tv is.
02:07 AM XXCoder: well unless its so loud I can feel it blasting away when im trying to sleep
02:08 AM Wolf_: need to hack XXCoder’s tv so when the volume goes up the CC gets bigger
02:08 AM XXCoder: lol
02:08 AM XXCoder: sadly captions is very broken standard
02:08 AM XXCoder: not all machines work with it now.
02:09 AM Wolf_: comcast has it built in to the x-one boxes
02:09 AM XXCoder: I still have ancient caption machine I use to caption projector whenever I want to use it. havent used it 2016 and doubt it this year also.
02:14 AM cncnoob: Hey guys. Why when I run my gcode does linuxcnc ask me to insert my first tool, but on other tool changes it does not ask me to change the tool?
02:15 AM Wolf_: cam filter has tool changes in it right?
02:15 AM cncnoob: what is cam filter?
02:16 AM Wolf_: thing that makes the cad in to gcode = cam
02:16 AM cncnoob: Oh, never heard it referred to as that
02:16 AM Wolf_: usually needs to set to what machine its making gcode for
02:17 AM cncnoob: I'm using Camworks and I have searched for such an option. It may (probably) has it, but I have been unable to locate it.
02:17 AM Wolf_: then you might need to dig in the gcode by hand and see what its calling when tool change is needed
02:19 AM XXCoder: cncnoob: is your HAL set to ask you to change tools?
02:19 AM XXCoder: mine asks me for each tool
02:19 AM cncnoob: I'm not sure
02:19 AM cncnoob: Thus far I have managed to avoid editing the HAL file directly
02:19 AM cncnoob: I've only had to edit the INI
02:20 AM Wolf_: oh yeah, forgot about that
02:20 AM Wolf_: need to set it to call for change vs auto tool change I think
02:20 AM XXCoder: yeah
02:20 AM Wolf_: been a while since I set a machine up lol
02:21 AM cncnoob: ok, let me step out to the shop and check that
02:22 AM XXCoder: wolf very recent for me LOL
02:23 AM Wolf_: yeah
02:23 AM Wolf_: right now I have laser info overload
02:23 AM Wolf_: now if I could remember which mirrors I needed…
02:24 AM cncnoob: loadusr -W hal_manualtoolchange
02:24 AM XXCoder: heard hard drive makes for nice mirror. first surface mirrors.
02:24 AM cncnoob: that is what I see in my hal file
02:26 AM Wolf_: I read copper mirror is pro
02:26 AM cncnoob: ah wait
02:26 AM cncnoob: when I go to show hal config in the linuxcnc gui I see the manualtoolchange line says false
02:26 AM cncnoob: hummm
02:26 AM XXCoder: weird
02:26 AM XXCoder: problem is you edited ini
02:27 AM XXCoder: it might get overwritten if you change and save in stepconf (or that pther configurer)
02:28 AM cncnoob: I have only edited the homing portion of my INI after running the stepconf originally
02:29 AM Wolf_: yeah, I cheat with that, I did my first setup using the wizard, copied that over to a machine called Setup_CNC, then hand edited all the other stuff needed in, then when I mess with steps and whatnot I just used the setup_cnc w/ stepconf and then open both side by side to edit settings
02:29 AM cncnoob: I keep the original copy and diff it when I make changes just to make sure I don't jack anything up :)
02:29 AM XXCoder: oh if it gets wiped you should be able to redo it. just save backup
02:29 AM XXCoder: indeed.
02:29 AM XXCoder: theres nice compare utilities in linux even.
02:29 AM XXCoder: diff doh
02:29 AM cncnoob: meld is pretty good
02:29 AM cncnoob: not as good as beyond compare
02:29 AM cncnoob: but free
02:29 AM Wolf_: I’ll also copy lines and then comment them out like nots in ini
02:29 AM Wolf_: nots/notes
02:30 AM Wolf_: so have original setting + change right in the ini
02:36 AM cncnoob: Yeah, so the code mentioned here is exactly what is in my HAL file:
02:36 AM cncnoob: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Tool_Changes
02:58 AM Wolf_: well, thats less painful got a quote for $1078 for 100w RECI tube and DY13 psu…
03:09 AM XXCoder: err not bad
03:09 AM XXCoder: 400 bucks less
03:10 AM Wolf_: yeah, waiting for a reply back about a different laser PSU, other one has a smart display with output levels and error messages
03:21 AM XXCoder: hopefully cheaper
03:21 AM Wolf_: will find out… lol
03:21 AM Wolf_: should be a few $$ more
03:22 AM Wolf_: the other W4 listing + P14 was $1596 shipped lol
03:31 AM MacGalempsy: time to meet a custom glass blower?
03:31 AM XXCoder: he has lab stuff access
03:32 AM Wolf_: lol I wish, still would need to get the lens/mirrors on the glass perfect and no gas leak
03:40 AM Wolf_: I’m still impressed that can get stuff like this for so damn cheap
03:41 AM Wolf_: shipping on the lower cost quote was $430, tube and PSU was only $648...
03:41 AM XXCoder: interesting
03:43 AM Wolf_: waiting for quote w/ W4 100W tube + HY-Z100 psu + mirror/lens set (x2) and a full hardware kit with all the mirror mounts, cutting head, tube mounts, stepper mount and gears/belts
03:45 AM Wolf_: then it would be just add some 80/20 and linear guides and a smoothy and got most of a laser cutter lol
03:46 AM XXCoder: indeed
03:46 AM XXCoder: too bad theres no 100w lasr diode
03:46 AM XXCoder: no need for glass tube
03:58 AM XXCoder: wb
04:07 AM Wolf_: man some of these sellers on ali are a mess lol
04:07 AM XXCoder: yeah?
04:07 AM Wolf_: well the listings anyways
04:08 AM Wolf_: https://www.aliexpress.com/store/product/whole-set-mechanical-components-for-installing-a-co2-laser-cutting-machine-laser-head/2803236_32775489825.html
04:08 AM Wolf_: try to figure out wtf your buying here lol
04:09 AM XXCoder: looks like tube holders, nema23 holdersm carrage, gearings
04:09 AM XXCoder: small mirror holder
04:09 AM XXCoder: dang shipped price jeez
04:09 AM Wolf_: yeah, I asked about that set and they asked why I needed the whole machine frame set lol
04:10 AM XXCoder: they seriosuly asked that?
04:10 AM XXCoder: I wouldnt care
04:10 AM XXCoder: sell sell sell
04:10 AM XXCoder: I dont care if buyer want to use it as intended or sex aids
04:11 AM Wolf_: I just wanted the quote on the crap in the pics lol
04:11 AM XXCoder: price seem to be 218 bucks, 112 bucks to ship
04:12 AM Wolf_: might as well bundle to save on shipping, https://www.aliexpress.com/store/product/Co2-Laser-Cutter-Parts-engraved-machine-Parts-Hardware-Transmission-Laser-head-Mechanical-Components/2803236_32795455589.html
04:12 AM XXCoder: I wonder how much vacuum depost system costs
04:13 AM Wolf_: that set is $27 lens, mirror $10ea, mirror holders $15 ea and $25 for the head
04:14 AM XXCoder: while trying to find metal depost vacuum I see mens penis pump :P
04:14 AM Wolf_: lol
04:14 AM XXCoder: guess they dont sell that
04:14 AM XXCoder: metal deposting system
04:14 AM Wolf_: maths $112 so thats kinda spot on...
04:15 AM Wolf_: this should mess with them some, I asked for 2 first mirror mounts lol
04:16 AM XXCoder: lets see what happens.
04:16 AM XXCoder: I was just wondering if it would be cheaper to make your own
04:16 AM XXCoder: first surface mirrors using vacuum depostion system
04:17 AM Wolf_: $15 for http://www.lightobject.com/25mm-Reflection-Mirror-Mount-for-CO2-Laser-Machinelong-version-P1066.aspx
04:17 AM Wolf_: lol @ that price as well
04:17 AM Wolf_: had idea to get a extra mirror mount and mod it to do http://www.lightobject.com/Laser-Machine-25mm-Beam-Combiner-Mount-wLaser-Pointer-Black-P1000.aspx
04:20 AM XXCoder: aha!
04:20 AM XXCoder: electroplating!
04:22 AM Wolf_: I dunno why but I have a 10 pack of red laser diodes lol
04:22 AM MacGalempsy: lol. cut and get a bigger pecker
04:23 AM XXCoder: fancy
04:24 AM XXCoder: wolf is it strong enough to burn anything?
04:24 AM XXCoder: if so, maybe fancy pattern cutter lol
04:24 AM jesseg: I've been electroplating copper through PCB holes
04:25 AM XXCoder: I was wondering about electroplating to make first surface mirrors.
04:26 AM jesseg: you need a conductive thing to electroplate onto, but then could work, but getting a thick and shiny electroplate is tricky
04:26 AM jesseg: I think vapor deposition is probably the best way to make mirrors
04:26 AM Wolf_: how do you plate holes?
04:27 AM jesseg: in fact I have plans to try making a carbon rod arc furnace to boil copper to see if I can vapor plate that way
04:27 AM XXCoder: jess vapor depostion is that where theres sealed vacuum box area where metal is umm slightly vaporized and metal deposts on object you want
04:28 AM jesseg: Wolf_, first with a mixture of varnish, thinner, and lots of graphite powder to get the holes initially conductive.. then electroplate that http://videoflier.com/movies/1488316104723273500907
04:28 AM jesseg: XXCoder, yeah, but I wanna try without the vacuum
04:28 AM jesseg: probably won't work but when I try I will know :D
04:28 AM XXCoder: cant be done for some metals
04:28 AM XXCoder: copper probably fine?
04:28 AM XXCoder: it dont oxide that fast. alum would
04:28 AM Wolf_: hmm neat
04:28 AM jesseg: besides, I've seen instances where an electrical short caused the vaporization of a copper contact or wire which in turn gave some copper film on nearby objects
04:32 AM XXCoder: jesseg: I wonder how easy to build vacuum depostion lol
04:32 AM XXCoder: it'd be fun to metal coat stuff
04:33 AM XXCoder: hmm alum metal coated phone screen. ;) jk
04:34 AM jesseg: XXCoder, yeah I thought about that. A friend offered me the use of his vacuum deposition system -- big plastic vacuum jar, table, pump -- so maybe at some point I can experiment. I actually have another friend who's done it using the little tungsten "Boats" to boil various metals in a high vacuum to plate them onto mylar
04:34 AM jesseg: so yeah I think it's reasonably straight forward
04:34 AM jesseg: probably with a thousand little gotchas to get really good results:P
04:35 AM jesseg: good night folks
04:36 AM XXCoder: night
05:24 AM jthornton: morning
05:26 AM XXCoder: hey jt
05:27 AM jthornton: what's up this weekend
05:27 AM XXCoder: not much just figuring what my options is on cam
05:28 AM jthornton: do you have a windows pc and unlimited internet?
05:28 AM XXCoder: also figuring how to make tachmeter holder for my machine
05:28 AM XXCoder: no and yes
05:28 AM XXCoder: no on latter actually
05:29 AM XXCoder: 1 tb, go over 10 bucks each 10 gb
05:29 AM XXCoder: larhe homehold so we go over sometimes.
05:29 AM jthornton: you can still use fusion 360 offline like I do
05:29 AM XXCoder: no windows sadly
05:29 AM XXCoder: it dont like to run in vbox
05:30 AM XXCoder: because video memory need to be more than 256 mb
05:30 AM jthornton: oh yea you need a real windows pc to run it
05:30 AM XXCoder: and vbox keeps saying nothing ever in universe needs more than 256 vram
05:30 AM XXCoder: jeez
05:30 AM XXCoder: reminds me of that bill gates and 514kb
05:31 AM jthornton: I don't really care for fusion 360 making you "log in" from time to time
05:32 AM XXCoder: i dont care much for cloud based storage also
05:33 AM jthornton: it's making me sign up now as it's been over a month since I installed it
05:33 AM jthornton: which was just a few clicks so not bad really
05:34 AM jthornton: are you needing 2D or 3D cad?
05:34 AM XXCoder: im thinking dxf to gcode for now
05:35 AM jthornton: I wrote a golang dxf to gcode program a while back
05:36 AM XXCoder: cool
05:36 AM jthornton: https://github.com/jethornton/DXFtoGcode
05:37 AM XXCoder: hmm
05:37 AM XXCoder: https://sourceforge.net/projects/dxf2gcode/
05:38 AM jthornton: yea saw that one a while back
05:38 AM XXCoder: http://www.delcam.com.tw/artcam/about.html
05:39 AM XXCoder: oh other artcam is now autodesk
05:39 AM XXCoder: seems everything is autodesk now
05:39 AM jthornton: isn't there a pycam
05:40 AM archivist: pycam just got a kick in the backside and restarted
05:41 AM XXCoder: last update couple weeks ago'
05:42 AM archivist: see http://highlab.com/~seb/blog//2017/02/23/open-source-cad-cam-mc/
05:42 AM XXCoder: honestly most of my parts probably will be 2d
05:42 AM XXCoder: "2.5" artwork would be done by image height maps
05:43 AM XXCoder: guy uses solvespace
05:43 AM XXCoder: I like that cad
05:48 AM XXCoder: cambam any good?
05:49 AM XXCoder: build is sept 2015
05:49 AM XXCoder: sounds not updating anymore.
05:49 AM XXCoder: ah dev build jan 2017
05:51 AM malcom2073: I really like cambam
05:51 AM jthornton: I need something quick and easy for my plasma cutter (sheetcam is ok)
05:56 AM XXCoder: sheetcam dont seem limited on linux version
05:56 AM XXCoder: rest has 180 line limit
05:56 AM XXCoder: I hate it when website has what seem to be button but only text itself is clickable
05:57 AM XXCoder: sheetcam can do routers
06:01 AM XXCoder: dolphincam surfcam
06:01 AM XXCoder: :P
06:01 AM XXCoder: wonder when there will be pervertcam
06:07 AM jthornton: https://www.youtube.com/watch?v=H00q4QrnnSs&list=PLYsWjANuAm4o0zcX7RwmJxtflFGyTKwdY&index=29
06:10 AM XXCoder: https://www.shapeoko.com/wiki/index.php/CAM
06:21 AM XXCoder: gsimple "current version" jan 30 2009
06:21 AM XXCoder: its 8 years old.
06:35 AM XXCoder: looks like its fusion 360
06:36 AM XXCoder: rest is either shitty, expensive or million years old
07:40 AM XXCoder: hey jthornton you alive?
07:40 AM XXCoder: or maybe JT-Shop
07:49 AM * JT-Shop gets a fire going in the shop
07:51 AM XXCoder: http://beatty-robotics.com/cnc-mill/ check this out
07:51 AM XXCoder: used 2020 beams to make case. i wonder if I can do that also
07:58 AM Tom_itx: jt's box would be of 2" thickwall square tubing
07:58 AM Tom_itx: with 'feet' welded to the bottom :)
07:59 AM XXCoder: epoxy concerete case for me then
07:59 AM XXCoder: 3 inches thick arund bottom, and lid is just one inch thick, no need for overkill
07:59 AM XXCoder: ;)
07:59 AM Tom_itx: you can 'see' the lack of rigidity of the mill in the turner's cube
08:00 AM XXCoder: one I linked to?
08:00 AM Tom_itx: of course
08:00 AM XXCoder: its 6 years old post dunno what its current condition is.
08:01 AM Tom_itx: 6yrs older
08:01 AM JT-Shop: if you added some 2" plate to the 2020 it would be rigid lol
08:01 AM Tom_itx: morning jt
08:02 AM Tom_itx is now known as Tom_L
08:03 AM JT-Shop: in reality plating the sides of a box frame would be pretty rigid but the gantry needs good linear slides to be rigid
08:03 AM JT-Shop: morning Tom_L
08:03 AM XXCoder: jt it seem to stop on sides so slightly less rigid than mine as it has sliding bottom plate on glantry also
08:03 AM XXCoder: and no front protective plate on front, that also helps rigidity
08:04 AM JT-Shop: got a link to yours?
08:04 AM XXCoder: you saw video of it dry running
08:05 AM XXCoder: https://www.youtube.com/watch?v=1JMSRF6Q9uw
08:07 AM JT-Shop: I've slept since then lol
08:10 AM JT-Shop: yea yours looks pretty rigid
08:10 AM XXCoder: its pretty nice
08:10 AM XXCoder: just need real enclosure so it can run stuff better, and coolant!
08:10 AM XXCoder: it made downstairs living room bit dusty that area lol
08:10 AM XXCoder: bamboo dust
08:16 AM XXCoder: anyway
08:16 AM XXCoder: night JT-Shop
08:19 AM JT-Shop: good night
08:20 AM jym: XXCoder: You need to fire the camerman, or at least have have him stop drinking 20 cups of coffee ;)
08:24 AM jym: JT-Shop: Does your wood stove heat the whole shop?
08:24 AM JT-Shop: is there a way to connect a USB scale to the LAN?
08:24 AM JT-Shop: and the garage too
08:24 AM jym: nice
08:25 AM jym: JT-Shop: How long does it take from a cold firebox?
08:25 AM JT-Shop: how long does what take?
08:25 AM jym: to make the shop/garage toasty?
08:26 AM JT-Shop: well it's 60F this morning in the machine shop so not long
08:26 AM jym: JT-Shop: And when it's <40F outside?
08:26 AM JT-Shop: 30F outside
08:26 AM jym: oh
08:27 AM jym: JT-Shop: how thick is the ceiling insulation?
08:27 AM JT-Shop: usually it never gets below 50f in here overnight
08:27 AM JT-Shop: 16.5"
08:27 AM jym: THAT would explain it, =)
08:28 AM JT-Shop: same in the house
08:29 AM jym: I have no clue why, but the garage is ALWAYS (summer/winter) colder than it is outside.
08:31 AM JT-Shop: it's possessed
08:31 AM jym: Heh, I think you're right.
08:35 AM jym: I had come to an impasse yesterday with my "barrel stove"... I kept feeding it 2" splits every 15 minutes for 5 hours, and I couldn't get up up to temp, and if I tried feeding it 4" splits, I'd smother it out.
08:37 AM jym: If the rain/snow storm permits, I think I'm going to try "reducing" the firebox by raising the burn up by half and put a sort of shelf there.
08:37 AM Tom_L: JT-Shop, some routers allow a connection for a USB printer.. i dunno if a scale would work there or not
08:38 AM jym: I'm using 3" pipe, but the thing is THIS uses 3" pipe too and it burned cordwood no problem http://www.sportsmansguide.com/product/index/hq-issue-outdoor-wood-stove?a=1884248
08:38 AM jthornton: hmm, I'll have to look at my router... if I can move the shipping scale off the desk it would be nice
08:39 AM jym: So volume has to have some impact I'm guessing.
08:39 AM jthornton: is yours like that one?
08:40 AM jym: No, I bought/return that one because the pipes are large end down and it leaked cresote like crazy on the outside of them. Mine is a vertical 55gal drum
08:41 AM jym: I just mentined it because it had no issue using 3" pipes
08:41 AM jym: ...and cordwood instead of 2" splits.
08:41 AM jym: I'm just trying to eliminate cause/effects
08:41 AM jthornton: do you have a grating in the firebox?
08:42 AM jym: No
08:42 AM jym: well, sorta, just soem 1/2" pipe to raise off the floor
08:43 AM jym: But if that little thing can burn cordwood using a 3" pipe, and my bralle stove using 3" pipe can't, it HAS to be something to do with the volume I'm speculating.
08:43 AM jym: barrel*
08:44 AM jym: When I had that little thing, it had no grating on the bottom of it either.
08:44 AM jthornton: on all three of my wood stoves/heater once I get a bed of coals going you can't smother the fire out with more wood
08:45 AM jthornton: the wood stove in the garage is very very small...
08:45 AM jym: I tried yesterday for 5 hours, feeding it (on a timer) every 15 minutes.
08:45 AM jthornton: do you have air coming into the firebox from below?
08:45 AM jym: Yes, 3" pipe for freesh air
08:45 AM Tom_L: your spend energy should have been enough to heat the room :)
08:46 AM jym: wait, no not below, but from the side
08:46 AM Tom_L: below will pull the air thru
08:46 AM jym: Tom_L: you're the 2nd person to say that
08:46 AM jym: Tom_L: I realize that, but it's the bottom of the barrel then =)
08:46 AM jthornton: well only my wood heater in the new shop has a grating and a bottom air inlet...
08:47 AM jthornton: can you get a good hot bed of coals going at all?
08:47 AM jym: But, if I place a shelf in the middle of the barrel, that would reduce volume AND allow "air from below"
08:47 AM jthornton: how high is the chimney above the roof?
08:48 AM jym: jthornton: Oh yeah, no problem gettings a very nice bed of coals,.... using 2" splits. It's when I put in 4" or larger that it smothers out.
08:48 AM jthornton: sounds like poor draft then
08:48 AM jym: jthornton: I tried 5ft and then 10ft, no difference
08:48 AM archivist: 100ft
08:49 AM jym: archivist: SOLD! haha
08:49 AM jthornton: got a photo of your creation?
08:49 AM * archivist points at the maths for HP of a chimney
08:49 AM Tom_L: at 100ft you could use it to smoke signal the next town
08:49 AM jym: jthornton: monstrosity? Yep, just a sec...
08:49 AM jym: Tom_L: Shit, I can do that now at 5ft
08:50 AM archivist: you need height 5/10 ft is bugger all
08:50 AM jthornton: non of mine are more than a couple of feet above the roor
08:51 AM jthornton: or roof even
08:51 AM * jthornton checks his current data usage being early in the month
08:52 AM Tom_L: the height of the pipe would depend where it is on the roof
08:52 AM Tom_L: if it's in the middle (below the ridge) it would need to be higher
08:52 AM jthornton: the new shop and the machine shop are all as close to the wall as possible for the stove/heater
08:53 AM Tom_L: air rolls over the ridge
08:53 AM Tom_L: could cause a downdraft if it's not high enough
08:53 AM jthornton: depends on many factors
08:53 AM jym: 2ft above the ridge line is code
08:53 AM Tom_L: generally..
08:53 AM Tom_L: jym, and that's why
08:54 AM jym: jthornton: http://imgur.com/3gCgTwJ
08:54 AM * jthornton has no codes lol
08:54 AM Tom_L: does so
08:54 AM Tom_L: gcodes
08:54 AM jthornton: :)
08:54 AM jthornton: jym: got any holes in the door?
08:55 AM jym: jthornton: No, there's a 3" pipe coming into the side 4" up fomthe bottom of the barrel
08:55 AM jym: on the back side
08:56 AM jthornton: I'd think you would be better with a few 1" holes in the door down low as possible to get a fast moving draft
08:56 AM jthornton: the 4" is bigger than the chimney and that might be the problem
08:57 AM jym: jthornton: Sorry, the intake and exhaust both are 3" exhaust pipe http://imgur.com/sSmwfpF
08:58 AM jym: jthornton: It's just postioned 4" up from the bottom
08:58 AM jym: the coffee can is just to atch embers from flying out
08:58 AM jym: catch*
09:01 AM jym: I think I'm just going to making the existing door the ash cleanout, and cut a new door near the top half of the barrel and put a mesh shelf/burn tray in there.
09:02 AM jym: Then fresh air will be pulled up thru the coals, and reduce the volume of the burn area
09:04 AM jym: cause there is no damn reason why this can burn cordwood using a 3" pipe and the barrel shouldn't be able to http://www.sportsmansguide.com/product/index/hq-issue-outdoor-wood-stove?a=1884248
09:06 AM jym: Funny thing, that lil guy actually fits in the barrel almost perfectly.
09:07 AM jym: You could use a barrel as a heat/rain shield for it. lol
09:17 AM JT-Shop: just take a step drill and make a few holes in the door down real low and block off the 3" pipe
09:18 AM JT-Shop: unless the fire is above the 3" pipe the air is just taking a trip through the stove and not feeding the fire
09:20 AM JT-Shop: also if you have room for a horz barrel stove the kits are cheap
09:24 AM jym: I dont have the clearances for a horizontal barrel being the ssue.
09:25 AM jym: I dont have time to mode the barrel before the snowfall,but I'm going to try raising the bottom up ABOVE the intake with some brick and grate I have.
09:25 AM JT-Shop: and the 3" pipe is on the wrong side, air fluid takes the path of least resistance and in your case right up the side of the barrel and out the chimney
09:25 AM JT-Shop: extend the pipe to the opposite side of the chimney
09:26 AM jym: IT's current positiion was based on a existing holes, if I can get some progress, I'll just get another barrel and posion them as you suggest
09:27 AM jym: I made it with the intension of the barrel ebing burnt out every year or so, so everythng "bolts on"
09:28 AM JT-Shop: you want the feed air to have to cross the fire before going out
09:28 AM JT-Shop: do you have some firebrick?
09:47 AM jym: JT-Shop: I have soem clay brick I can use for now, and I can make some refactory brick sized to fit the barrel later.
11:39 AM JT-Shop: for a quick experiment block off the pipe and crack the door open about 1/2"
12:11 PM [cnc] is now known as [cube]
01:05 PM jym: JT-Shop: Ok, I blocked off all the airholes. Tossed the thing on ciderblocks in a U shape, and removed the 2" bung cap. Then cracked the door 3/4". Got a nice bed of coals going, toss on a piece of cordwood and started smoldering (though slower then previously). So I'm thinking it's not so much volume, but flow being the issue.
01:09 PM jym: the bung cap is on the lid, or in this case, on the bottom right below the coals dead center.
01:12 PM JT-Shop: close the door if you have a 2" hole in the bottom
01:13 PM jym: JT-Shop: I tired that first, a little too small I believe. Then I cracked the door.
01:14 PM jym: I placed a piece of expanded steel over the hole too
01:19 PM jym: JT-Shop: http://imgur.com/a/5Ta0V
01:22 PM jym: That's all the testing for today, snowstorm coming and I'm just waiting for this thing to smolder out to pull it in the garage
01:24 PM roycroft: so there's a south bend 9a for sale that looks to be in great shape for $2250
01:25 PM roycroft: obviously rebuilt, but the flaking on the ways and saddle is still visible and it seems there's almost zero wear
01:25 PM jym: roycroft: how many thousands of miles away?
01:25 PM roycroft: it's local
01:25 PM roycroft: that's more than i want to pay
01:25 PM jym: ah
01:25 PM roycroft: but i wonder if it's worth pursuing
01:26 PM roycroft: https://eugene.craigslist.org/tls/6022660312.html
01:26 PM roycroft: it's been advertised for at least a couple months
01:26 PM roycroft: i've ignored it because of the price
01:26 PM roycroft: but i might be able to talk him down since it's been listed for so long
01:26 PM jym: probably why nobody has grabbed it
01:26 PM malcom2073: Holy crap that's expensive
01:27 PM roycroft: yeah, but it appears to be in almost mint condition
01:27 PM malcom2073: It looks too new, reworked maybe?
01:27 PM roycroft: certainly reworked
01:28 PM roycroft: but if someone is going to scrape and flake it that skilfully then it's probably very straight
01:28 PM malcom2073: True, that is a really consistant flake
01:28 PM malcom2073: And it has a DRO
01:28 PM roycroft: anyone who is that skilled is not going to do a "quick flake job" on worn out lathe to try to sell it
01:28 PM malcom2073: Alright so that might actually not be a terrible deal
01:28 PM JT-Shop: jym: that smoke coming out of the door indicates a poor draft up the chimney
01:28 PM roycroft: yes, it has a dro
01:29 PM os1r1s: Anyone use vise keys?
01:29 PM roycroft: and i would use it manually, so a dro would be useful
01:29 PM malcom2073: DROs are amazing
01:29 PM JT-Shop: I leave my vise unlocked
01:29 PM malcom2073: I really need to put one on my lathe heh
01:29 PM os1r1s: JT-Shop Don't like vise keys, haven't bothered, or need the flexibility too often?
01:29 PM malcom2073: os1r1s: Yeah, I love them
01:29 PM roycroft: the drawback is that it doesn't come with the desk
01:30 PM jym: JT-Shop: When the barrel temp is a bit low, the smoke reappears. Open door, temp rises, smoke goes away, close door, smoke builds up, temp lowers, lather rinse repeat.
01:30 PM roycroft: i like the metal south bend desks - the drawers are designed to hold tooling really nicely
01:30 PM malcom2073: os1r1s: It's a good time saver
01:30 PM os1r1s: malcom2073 Did you mount the vise upside down clamped to something to mill them?
01:30 PM roycroft: if i could get that for $1750 would that be an ok deal?
01:30 PM malcom2073: os1r1s: I have a kurt, so it had provisions already
01:31 PM os1r1s: malcom2073 Mine has provisions, but the keys are 5/8 and I need to drop them down to 1/2"
01:31 PM malcom2073: Ah, yeah probably easiest to clamp the vise upside down then, make sure to indicate it to ensure it's straight
01:31 PM roycroft: it looks like it's probably about 24" between centers, which is fine
01:31 PM os1r1s: malcom2073 Are yours a very close/tight fit/
01:32 PM malcom2073: os1r1s: Mine won't go in unless perfectly clean, so yeah very tight
01:32 PM malcom2073: I'm unsure if I could actually machine that close of a tolerance heh
01:34 PM os1r1s: malcom2073 My vise is too big for the table. So the vise keys will help me line it up long ways as well as remount
01:34 PM malcom2073: +1, it makes remounting way quicker.
01:35 PM JT-Shop: jym: is the 2" hole in the bottom blocked in any way?
01:39 PM JT-Shop: 3" pipe has 7.07sq/in 4" = 12.57sq/in 6" = 28.27sq/in I think I see the problem with your flue pipe
01:39 PM JT-Shop: mine are all 6"
01:44 PM jym: JT-Shop: The 2" bung hole only has a piece f expanded steel over it.
01:44 PM JT-Shop: os1r1s: I guess if you take your vise off a key would be nice, would only work on one of my machines
01:46 PM jym: JT-Shop: Yes, that's correct 3" mine, 6" yours/typical. My flue pipe is dble-wall "low temp" (<600F) meant for pellet stove, but I'm okey with 800F flue gas temps. If I used 6" I'm look at 1200F flue gas temps and I just don't have the clearance from combustables for that.
01:47 PM Wolf_: trick is that pellet stoves used forced air blower to draft
01:47 PM os1r1s: JT-Shop Do you reindicate every time you take off your vise?
01:47 PM jym: This also uses 3" pipe, and it burns cordwood just fine... http://www.sportsmansguide.com/product/index/hq-issue-outdoor-wood-stove?a=1884248
01:48 PM jym: and that box stove actually fits inside of a 55gal drum
01:57 PM JT-Shop: it's a different shape than yours...
01:57 PM JT-Shop: os1r1s: I never take them off...
01:57 PM JT-Shop: but if I did it only takes a few minutes to dial one in
02:05 PM os1r1s: JT-Shop Honeslty I think setup is the most painful part of machining. So trying to reduce optimize that time is ideal
02:05 PM JT-Shop: jym: how did you calculate flue temperature based on diameter?
02:06 PM JT-Shop: I agree, I spend more time squaring and setting up than machining
02:07 PM JT-Shop: but if you take your vise off regularly it makes sense to be able to quickly get it close to parallel
02:08 PM JT-Shop: jym: that stove has a 6.45" flue pipe!
02:13 PM Tom_L: Five 15.5"l. interlocking stove pipes with 3.375" diameter is what the link says
02:14 PM Tom_L: mmm the pic says different
02:15 PM Tom_L: so confusing
02:16 PM jym: JT-Shop: 6.45 FEET (length)
02:18 PM jym: 5 * 15.5" = 77.5" / 12" = 6.45833333333333 feet
02:19 PM JT-Shop: it's also a different shape
02:19 PM JT-Shop: so how did you get the flue temperature based on diameter? my 6" never gets 1200F
02:22 PM jym: JT-Shop: Max (rated) temps, apx
02:23 PM JT-Shop: ah, you don't have to run them that hot :)
02:24 PM jym: JT-Shop: Sure, but 3" limits what can happen.
02:24 PM JT-Shop: not really
02:24 PM jym: It's FAR too easy to overtemp even a real wood stove
02:29 PM jym: JT-Shop: That's a 6" duct just for scale reference... http://imgur.com/a/VLaVs
02:29 PM JT-Shop: I know what a 6" flue pipe looks like I have 3 of them
02:30 PM JT-Shop: not really, if you control the oxygen going in you control the fire period
02:30 PM jym: JT-Shop: Not of YOUR pipe, of the box stove vs barral
02:31 PM JT-Shop: why do I want to look at it?
02:31 PM jym: If you limit the smoke going out, you limit the oxygen going in too
02:31 PM JT-Shop: being frugal at the start of the month with GB's
02:31 PM JT-Shop: same difference
02:31 PM JT-Shop: they call them dampers
02:32 PM jym: and 3" exhausts in my cause =)
02:32 PM Tom_L: hook an oxy tank to it
02:32 PM Tom_L: that'll make it burn
02:32 PM JT-Shop: but your heater doesn't work!
02:33 PM JT-Shop: or a blower up the bung hole
02:33 PM Tom_L: JT-Shop
02:33 PM Tom_L: if i remove a channel from the logs, at what point does the primary index get rebuilt?
02:33 PM Tom_L: or does it
02:33 PM jym: Ok, added a pic of the box stove sitting in the barrel http://imgur.com/a/VLaVs
02:34 PM Tom_L: i don't get the whole stove in a barrel thing anyway
02:35 PM jym: Tom_L: I was curious if it would fit and it did. Plus I wanted to store it out of the rain and
02:36 PM JT-Shop: the next day iirc
02:36 PM Tom_L: ok
02:37 PM JT-Shop: why would I want to look at a box stove in a barrel?
02:37 PM jym: Tom_L: Also, I wanted to see if the barrel would make a nice heat shield for the stove
02:37 PM JT-Shop: probably would work good for that
02:39 PM jym: JT-Shop: I just wanted you to see that box stove burning cordwood using a 3" pipe compared to a 55gal drum using a 3" pipe, that's all =)
02:45 PM JT-Shop: it's like comparing apples and oranges two different things
02:47 PM jym: JT-Shop: Your bandwidth thing, you get what 10GB month, and unlimted after hours?
02:49 PM jym: JT-Shop: What you might consider is having a VPS with a caching proxy that will resize media on the fly. That way way you can still see things with reduced resolution, then grab the full res after hours
02:50 PM jym: JT-Shop: you could even filter out crap/ads right on the proxy
02:50 PM jym: JT-Shop: just a thought
02:54 PM JT-Shop: yea free time is 3am to 8am
02:54 PM JT-Shop: I try and keep adblock on all my pcs but when I change them sometimes I forget lol
02:57 PM Deejay: don't use internet without adblock. trust me. its bad. remember: adblock first!
03:01 PM jym: JT-Shop: you can even use SSH to proxy
03:01 PM jym: but not cache/filter
03:04 PM jym: JT-Shop: It's an orange disguised as an apple....
03:05 PM jym: JT-Shop: If I put baffles on each side, then on top at the height of the box stove, and one in the read close to the existing pipe opening, I would had the equiv of that box stove in a barrel.
03:05 PM jym: rear*
03:10 PM JT-Shop: or use fire brick to build a tunnel to the middle for the 3" inlet
03:17 PM jym: JT-Shop: I was thinker hardiebackker board, since it has a fire rating
03:23 PM JT-Shop: prob blow up at those temps and a box of fire brick is cheap
03:27 PM XXCoder: good morning
03:28 PM JT-Shop: morning
03:30 PM CaptHindsight: was odd that I had this 2.5" dia face mill on a 3/4" holder about 8" long
03:31 PM CaptHindsight: shortened the shaft to ~3" and it cuts with no patterns
03:32 PM CaptHindsight: were they surfacing deep pockets with it?
03:41 PM JT-Shop: jym: my small stove is a bit cold natured and I have to build a small hot fire from kindling to get it warmed up before burning bigger pieces of wood. You mentioned yours did draft ok when it was warm...
03:48 PM -!- #linuxcnc mode set to +v by karatkievich.freenode.net
03:53 PM jym: JT-Shop: If I butn just one newspaper ahead of building the fire, it updrafts great. Both the barerel stove, and my real wood stove in the house.
03:53 PM jym: one sheet of newspaper*
04:09 PM cpresser_ is now known as cpresser
04:32 PM roycroft: https://redding.craigslist.org/tls/6009968290.html
04:32 PM roycroft: so that's another possibility for a lathe
04:32 PM roycroft: it's closer than going to grizzly, but it's 4 mountain passes away
04:33 PM roycroft: worth checking out?
04:34 PM roycroft: i would need to get it for less than that price, for sure
04:35 PM roycroft: and i'm concerned that it's sitting outside
04:35 PM JT-Shop: yea
04:35 PM JT-Shop: may be under a roof though
04:35 PM roycroft: it doesn't look very rusty, but the pictures are pretty fuzzy
04:35 PM roycroft: and that's not a very wet area
04:36 PM JT-Shop: pretty old school stuff there
04:36 PM roycroft: old school can be good
04:36 PM roycroft: if it's tight
04:37 PM JT-Shop: I used to hate that kind of tool holder :)
04:37 PM roycroft: a nice rebuild project
04:37 PM roycroft: lantern toolpost would be gone in seconds :)
04:38 PM roycroft: $300 would get me a nice, new bxa qctp with some tool holders
04:38 PM XXCoder: so, on lathes what is "swing (size)?
04:38 PM roycroft: double the distance from centerline to ways
04:39 PM roycroft: i.e. biggest diameter round you can put in it
04:39 PM XXCoder: ahh ok thanks
04:40 PM JT-Shop: threaded spindle... had one of those too
04:41 PM roycroft: most older lathes have threaded spindles
04:41 PM roycroft: that one i was looking at the other day had a d1-4 camlock, and that was nice
04:41 PM roycroft: the shiny south bend i was looking at this morning has a threaded spindle
04:41 PM roycroft: i like the look of that rockford
04:42 PM roycroft: if i tore it apart and rebuilt it and repainted it it would look really great
04:42 PM roycroft: which is meaningless if it does not perform well
04:42 PM roycroft: but is a bonus vs. one that performs equally and looks like cheap imported junk
04:44 PM roycroft: it's a really long drive though, if i'm not pretty sure (5-6 hours, plus possible delay at siskiyou summit this time of year)
04:45 PM roycroft: that's each way
04:48 PM Deejay: gn8
04:51 PM roycroft: nice big spindle bore on that machine, for its size - 1-5/8"
04:51 PM roycroft: oops, misread
04:51 PM roycroft: it's 1-1/16"
04:51 PM roycroft: not so big
04:58 PM JT-Shop: that's another problem with threaded spindles... small through bore
04:59 PM JT-Shop: my Samson has a 2 1/16" spindle ID
05:00 PM roycroft: yes, that's a problem with them
05:09 PM JT-Shop: Myfordboy does some amazing things on a Myford
05:10 PM XXCoder: indeed
05:17 PM JT-Shop: I'll be so glad to get caught up on all these projects and have a little play time...
05:18 PM XXCoder: :)
05:19 PM XXCoder: im stuck
05:19 PM XXCoder: cant think of anything to make
05:20 PM malcom2073: Really?
05:20 PM JT-Shop: make me some wrench organizers for my combination wrenches :)
05:20 PM malcom2073: no improvements to make for the machine? :)
05:20 PM malcom2073: Or other garage gadgets?
05:20 PM XXCoder: mal ya was thinking that but im also uncertain on how to make gcode
05:21 PM malcom2073: Yeah without windows you're in a pretty hard spot there if you're doing anything more complicated than you can doby hand
05:21 PM XXCoder: yeah
05:21 PM XXCoder: well time to think up cabienet for my cnc rputer
05:22 PM XXCoder: it wont be complex
05:23 PM XXCoder: using freecad to think up board design
05:31 PM malcom2073: Something like that should be hand-codable at least once you design it
05:38 PM XXCoder: is there a way to buy really short lengths of parallel wire?
05:39 PM Tom_L: ribbon?
05:39 PM Tom_L: what do you mean?
05:40 PM XXCoder: oh a short parallel cable with connectors
05:40 PM XXCoder: maybe 3 feet or so
05:40 PM XXCoder: even better if it is female to male
05:40 PM Tom_L: how long are the ones pcw has?
05:40 PM roycroft: for cnc stuff?
05:40 PM Tom_L: or maybe JT has em too
05:40 PM XXCoder: roy yeah short ones for internal use
05:41 PM roycroft: you need ones with twisted, shielded wires
05:41 PM roycroft: a standard serial cable will not work
05:41 PM roycroft: i don't now how short the ones jt carries are
05:41 PM XXCoder: serial cable?
05:41 PM roycroft: but do not buy a 25 pin cable off ebay
05:41 PM XXCoder: im talking about thicker parallel port cable
05:42 PM Tom_L: make one
05:42 PM XXCoder: ebay ones no good? whats wrong with those?
05:42 PM Tom_L: buy ends and cut your own
05:42 PM roycroft: they won't have twisted, shielded pairs
05:42 PM Tom_L: custom length
05:42 PM roycroft: and you will cry
05:42 PM roycroft: and we don't want to see you cry
05:42 PM XXCoder: tom possibly. so many pins to match with wires though lol
05:43 PM XXCoder: and im not very good with soldering :P
05:43 PM roycroft: i got one from jt that is about 2m long
05:43 PM roycroft: longer than you want
05:43 PM roycroft: he may have shorter ones though
05:43 PM Tom_L: it's pretty easy if you plug the ends together and match them as you go
05:44 PM Tom_L: or just get ribbon ends and crimp em
05:44 PM Tom_L: then wrap it in foil
05:46 PM Tom_L: find some old scsi cables
05:49 PM Tom_L: http://www.staples.com/Monoprice-6-HPDB50-Male-to-DB25-Male-SCSI-Cable/product_1255125?cid=PS:GooglePLAs:1255125&ci_src=17588969&ci_sku=1255125&KPID=1255125&cvosrc=PLA.google-SALES.Computer%20Accessories%20%26%20Peripherals&cvo_crid=39357180702&cvo_campaign=173943942&gclid=CPyRmq3-vdICFUgbaQodScUJ2w
05:50 PM gregcnc: IEEE 1284 is the spec you need
05:50 PM Tom_L: those are probably better wire
05:50 PM Tom_L: cut in half and you'll have 2
05:50 PM Tom_L: add ends
05:50 PM XXCoder: heh current one is quite old
05:50 PM XXCoder: 1997 thereabouts
05:53 PM Tom_L: https://www.walmart.com/ip/IEC-M352002-SCSI-Cable-DB25-Male-to-DM50-Male-3/141587973?wmlspartner=wlpa&selectedSellerId=1573&adid=22222222227046916038&wmlspartner=wmtlabs&wl0=&wl1=g&wl2=c&wl3=123008029238&wl4=pla-286068136244&wl5=9024262&wl6=&wl7=&wl8=&wl9=pla&wl10=113137531&wl11=online&wl12=141587973&wl13=&veh=sem
05:54 PM Tom_L: male/male 3'
05:54 PM * XXCoder spots walmart part of url and dont click.
05:58 PM Tom_L: you can buy steppers from them too
05:58 PM Tom_L: they just broker for someone else
05:58 PM Tom_L: and comes with their return policy...
05:58 PM XXCoder: yeah and walmart gets a percentage
05:58 PM XXCoder: I dont want to give em even one penny
05:59 PM Tom_L: so does amazon, ebay,....
05:59 PM XXCoder: amazon eh but ebay is fine
05:59 PM XXCoder: amazon warehouse pickers can have hard time but not as bad as walmart workers
06:00 PM malcom2073: Tom_L: That isn't male/male, that's DB25 to DM50
06:00 PM Tom_L: they could have said no
06:00 PM malcom2073: or rather, *is* male, but wrong end
06:00 PM Tom_L: ahh
06:00 PM Tom_L: i wondered, the pic is wrong then
06:00 PM XXCoder: Tom_L: when walmart is only source of work?
06:00 PM Tom_L: still i think it's better wire
06:00 PM XXCoder: sometimes its not a choice
06:01 PM * Tom_L gives em some cardboard and a marker
06:01 PM XXCoder: homeless jokes is bength you
06:01 PM malcom2073: XXCoder: That's a *really* old argument.
06:01 PM XXCoder: been homeless for over a year
06:02 PM Tom_L: dude, there's one here that is a cripple half the day and a vet the other half
06:02 PM Tom_L: i kid you not
06:02 PM XXCoder: means every other homeless is faker?
06:02 PM Tom_L: it means i don't trust any of them
06:02 PM XXCoder: want to give something? give food or drink but not money
06:03 PM malcom2073: A good portion are homeless by choice, doesn't mean they all are, but to imply it's not a choice for anyone is as incorrect as implying it is for everyone.
06:03 PM XXCoder: simple solution if youre worried about that
06:03 PM Tom_L: anyway, back to the business of the day...
06:03 PM XXCoder: mal never said so
06:03 PM malcom2073: No, but you implied Tom thought so :)
06:04 PM XXCoder: when?
06:04 PM gregcnc: what is this cable for again?
06:04 PM malcom2073: Heh
06:04 PM malcom2073: It's to go to a BOB yeah?
06:04 PM XXCoder: yeah internal connection from wall to BOB
06:05 PM Tom_L: ribbon would be easiest probably
06:05 PM malcom2073: I'd get a china cable. As long as the pinout is right, at the speeds you're operating it doesn't matter much about shielding, and twisted pair doesn't do anything for lcnc (no differential signals)
06:06 PM gregcnc: oh thought mesa
06:07 PM XXCoder: the PWM board comes with board connectors, that surpised me, but BOB does not. where can I find board offset stands? not too sure on names
06:07 PM malcom2073: XXCoder: Metal standoffs for mounting the board to a plate?
06:07 PM XXCoder: those copperisg goldish colored offset stands same as computer motherboard standoffs
06:07 PM XXCoder: yeah
06:07 PM malcom2073: yeah standoffs, I get them from mcmastercarr. Shame you're not closer, I have a huge bag of 'em heh
06:08 PM Tom_L: i posted a standoff link for like a billion for a buck the other day
06:08 PM XXCoder: lol I should have pile of em somewhere but cant find
06:08 PM XXCoder: from old computers and so on
06:08 PM malcom2073: Tom_L: Repost? :)
06:08 PM XXCoder: not a huge pile
06:09 PM Tom_L: i keep mine in one of those plastic fishing tackle cases from walmart :)
06:09 PM XXCoder: so standoffs is right word?
06:09 PM malcom2073: afaik yeah, "hex standoffs"
06:09 PM Tom_L: lemme look
06:09 PM malcom2073: https://www.mcmaster.com/#standard-threaded-standoffs/=16m3s25
06:09 PM Tom_L: digikey has em for sure
06:10 PM XXCoder: 100 bucks for fancy black ones
06:10 PM XXCoder: m3 thread
06:10 PM XXCoder: 9 bucks for various sizes
06:10 PM XXCoder: https://www.amazon.com/Rosiness-M3-Stand-off-Accessories-Assortment/dp/B00LGBM3J8/
06:10 PM XXCoder: oh they cut free shipping to 35 bucks
06:11 PM malcom2073: Depends on the vendor, they also have "add-on-items"
06:11 PM malcom2073: which get free shipping only if bundled with a normal item
06:11 PM XXCoder: yah saw some of those
06:11 PM XXCoder: geez!
06:11 PM XXCoder: RED ones
06:11 PM malcom2073: I have prime, and it's annoying that they do that for prime too
06:12 PM malcom2073: Haha bright red
06:13 PM JT-Shop: goodnight
06:13 PM XXCoder: night JT-Shop
06:13 PM XXCoder: nylon ones
06:13 PM JT-Shop: happy wing night!
06:14 PM Tom_L: malcom2073, can't find it now but it was a alibaba.com link
06:14 PM XXCoder: https://www.amazon.com/Eowpower-160pcs-Female-Standoff-Assortment/dp/B01N9K7FJS/
06:14 PM malcom2073: Ah well heh, thanks for looking. Probably wouldn't've bought it now anyway, but I like that stuff anyway
06:15 PM XXCoder: I wonder if plastic board would work
06:16 PM XXCoder: I wonder what size bolts psus use
06:19 PM malcom2073: Computer ones? I think they're 4-40, but not sure
06:20 PM jym: XXCoder: do you walk into a store and ask "Where are your Power Supply UNITS?"
06:20 PM malcom2073: jym: How would you ask for it? "Do you sell multiple power supply unit"?
06:21 PM jym: malcom2073: I dont use the word UNIT,
06:21 PM jym: Where are your power supplys?
06:21 PM jym: I need a power supply
06:21 PM jym: etc
06:22 PM malcom2073: PSU colloquially means computer power supply, as opposed to any other random power supply
06:22 PM XXCoder: weird
06:22 PM jym: Not that I have ever seen written anywhere.
06:23 PM malcom2073: If I walk into a store and ask where their PSU's are, I'd expect them to point me to the computer section. If I ask them where their power supplies are, I'd expect them to ask me what voltage I need... as if such a nice store would exist that would carry both kinds :-P
06:23 PM XXCoder: big 400w psu has m3, so does standoffs on pwm board
06:23 PM jym: I dont see a "power supply uint" category
06:23 PM jym: unit*
06:23 PM malcom2073: jym: Really? https://en.wikipedia.org/wiki/Power_supply_unit_(computer)
06:23 PM XXCoder: but not smaller psu unit. it fits but dont rotate all way in
06:23 PM XXCoder: I'm guessing it has different thread but same size
06:23 PM Tom_L: get a pico psu
06:24 PM jym: Yeah, still not buying the whole PSU thing.
06:24 PM jym: Ps sure, but not PSU
06:24 PM malcom2073: Eh, could be a regional thing. East coast and west coast say PSU, wherever you are don't? :-P
06:24 PM jym: PS*
06:24 PM Tom_L: BS
06:25 PM jym: malcom2073: Uh silcone valley for 20 years?
06:25 PM malcom2073: Ah there's your problem, too trendy!
06:25 PM jym: haha
06:25 PM malcom2073: PSU is older than 10 minutes, so it'll fall out of use there
06:25 PM XXCoder: lol
06:26 PM Tom_L: is Arnold still in charge?
06:26 PM jym: I wasn't being condensending, just not somethign I would ever say, liek ever.
06:26 PM malcom2073: I was serious about it being regional, I hear it all the time when talking computer hardware
06:26 PM jym: "Ah hell the power supply unit blew up"
06:27 PM Tom_L: just like 'soda' and 'coke'
06:27 PM malcom2073: "What kind of Pee-ess-ewe are you gonna use?"
06:27 PM XXCoder: every channel that ever talked about psu always used psu
06:27 PM jym: "this power suplly is a POS"
06:27 PM jym: XXCoder: have you EVER heard someone speak "Power Supply Unit"?
06:27 PM XXCoder: I havent heard anyone speak ever,
06:27 PM XXCoder: so no I guess
06:27 PM jym: DOH, sorry
06:28 PM jym: well, you know what I mean though
06:28 PM jym: XXCoder: fine, sign it, whatever
06:28 PM XXCoder: yeah, when i was taking it/cs classes it was psu
06:28 PM malcom2073: Heh
06:28 PM XXCoder: thats quite a while aho
06:28 PM XXCoder: sign what form?
06:29 PM jym: but the WORD "unit" comes out
06:29 PM XXCoder: sorry just fuking with you :D
06:29 PM XXCoder: anyway yeah just write psu
06:29 PM XXCoder: dont really needed to write it out fully
06:29 PM jym: PS
06:29 PM XXCoder: I wouldnt say psu unit as thats repeative
06:29 PM jym: 300W ps
06:29 PM gregcnc: this just reminded me i had a truck i called a pieceoshitsu
06:30 PM XXCoder: but just psu, ps unit. never did fully expanded one of power supply unit
06:30 PM XXCoder: second one is pretty rare, just usually psu
06:32 PM XXCoder: bah that smaller psu seem to have different pitch thread than rest
06:32 PM XXCoder: uncertain on how to find correct places to bolt on for psus too since theres no diagram of bolt pattern
06:33 PM malcom2073: XXCoder: You could leave it in its case, and use a strap over the top?
06:34 PM XXCoder: well can always do that yeah or add flanges as it has different ones on sides also.
06:39 PM Tom_L: pico psu just mounts to the PC no muss no fuss
06:39 PM Tom_L: err MB
06:39 PM Tom_L: or is that CPU board?
06:47 PM jym: Tom_L: fuck you and the unit you rode in on =)
06:48 PM XXCoder: https://www.amazon.com/Eowpower-160pcs-Female-Standoff-Assortment/dp/B01N9K7FJS/
06:48 PM Tom_L: jym, you been in the smoke too long
06:48 PM XXCoder: might be better for plastic board
06:48 PM XXCoder: can bolt on from both sides
06:48 PM jym: Tom_L: Not today, I shut down everything before the storm came =)
06:49 PM XXCoder: smoke a bowl
06:49 PM jym: XXCoder: Not in decades =)
06:49 PM Tom_L: you light a fire here today it would be in canada by nightfall
06:49 PM XXCoder: lol
06:49 PM Tom_L: it's w i n d y a s s h i t
06:49 PM XXCoder: light a fire here and it will be nonexistant in minutes
06:50 PM jym: WX svc has a storm alert, suppose to get from 4-12" of snow here, and 4ft higher up
06:50 PM Tom_L: SNOW!
06:50 PM Tom_L: it was upper 60's here
06:51 PM jym: it's 44F @ 88% atm
06:51 PM XXCoder: I'm srtarting to forget what sun looks like.
06:51 PM XXCoder: been cloudy or rainy more or less constantly
06:51 PM jym: There actually was sun this morning
06:56 PM XXCoder: wow
07:43 PM XXCoder: aw
07:43 PM XXCoder: arcades is going exinact
07:43 PM XXCoder: only 35 left of orginial tube tvs
07:43 PM XXCoder: once thats gone only can refarbish old ones, and if broke no replacement.
07:45 PM XXCoder: https://gizmodo.com/as-crt-supplies-vanish-the-classic-arcade-machine-is-vi-1792968855
07:45 PM XXCoder: im wrong its less than 30 left now
07:53 PM jym: cradek_: Can't PS do "trig"? http://www.physics.emory.edu/faculty/weeks//ideas/spiral.html
07:57 PM MacGalempsy: good evening guys
07:57 PM malcom2073: Evenin
07:59 PM XXCoder: yo
08:00 PM MacGalempsy: XXCoder: you come up w a project idea yet?
08:00 PM XXCoder: kinda but kinda not
08:01 PM XXCoder: im thinking on how to do board design to mount electrics on
08:01 PM MacGalempsy: malcom2073 how did your guy like his lights?
08:01 PM malcom2073: He loves 'em
08:01 PM MacGalempsy: all aluminum farmbot!
08:01 PM MacGalempsy: love em enough for a 100 unit order?
08:02 PM malcom2073: not yet, the 18 I made him were enough for his greenhouse
08:02 PM XXCoder: all alum farmbot
08:03 PM XXCoder: isnt there kickstarter on that many moons ago
08:03 PM MacGalempsy: no idea.
08:03 PM MacGalempsy: saw it on a tv show recently
08:04 PM MacGalempsy: reg. farmbot that is.
08:04 PM XXCoder: ya want one lol
08:04 PM XXCoder: no place for it for now
08:05 PM XXCoder: ohh http://makezine.com/2017/02/27/chip-powered-apple-ii-mini/
08:05 PM MacGalempsy: just start making the small stuff
08:05 PM XXCoder: project for my CHIP maybe
08:06 PM MacGalempsy: heh. oregon trail. time to hunt!
08:06 PM MacGalempsy: so Malcom2073 whats the next cnc project?
08:08 PM malcom2073: No clue!
08:10 PM malcom2073: Working on programming projects atm, so nothing for the time being
08:10 PM malcom2073: Someday I have a 5x10 router to build....
08:11 PM XXCoder: would love to have router that big.
08:12 PM malcom2073: Me too, I have the rails
08:12 PM malcom2073: And a 6ft ballscrew for the X
08:21 PM MacGalempsy: 6ft ballscrew!
08:22 PM MacGalempsy: sweet. when i get home, im going to tune on my motors a bit and and continue on the tool changer code
08:22 PM malcom2073: Yeah, it's like 1.5" diameter
08:23 PM XXCoder: 6 ft isnt that not enough for 10ft?
08:23 PM MacGalempsy: might as well go for a router/plasma cutter
08:23 PM malcom2073: XXCoder: The 10ft is getting rack and pinion
08:23 PM XXCoder: ahh
08:24 PM MacGalempsy: and laser
08:24 PM MacGalempsy: multi-head
08:24 PM XXCoder: easy enough to do that yeah
08:24 PM malcom2073: Hah, I'd love a laser, waterjet, or plasma... but I'll stick to a router for now
08:25 PM MacGalempsy: lots of options with table that big
08:25 PM malcom2073: We have a waterjet next door at work, I'm gonna ask them how much to cut out parts... but I don't expect them to be cheap, they're lame
08:30 PM MacGalempsy: buddy up on smoke breaks
08:32 PM malcom2073: I can buddy up with the employees all I want, the tesla driving owner on the other hand....
08:32 PM MacGalempsy: heh. oh gawd a tesla driver? hahaha
08:32 PM MacGalempsy: good luck.
08:32 PM malcom2073: Not like the cheap one
08:32 PM malcom2073: The 120k one
08:33 PM XXCoder: fancy
08:33 PM MacGalempsy: thats not that much
08:33 PM XXCoder: I want elio
08:33 PM malcom2073: XXCoder: Me too
08:33 PM XXCoder: cant buy one at any price for now. bleh
08:33 PM malcom2073: Eh, either way, I think they're making good headway in that arena
08:33 PM malcom2073: If nothing else, than getting people interested in that sort of thing
08:33 PM XXCoder: indeed
08:34 PM MacGalempsy: i would like a 1962 mercedes 190sl
08:34 PM malcom2073: Buddy of mine had a 70's 300D
08:34 PM malcom2073: His name was Ben, it was "Ben's Benz"
08:34 PM MacGalempsy: 300D is 4 door diesel?
08:34 PM malcom2073: iirc, non turbo too
08:34 PM malcom2073: It was a dog, like 70hp
08:35 PM MacGalempsy: yeah.
08:35 PM malcom2073: It was kinda fun though, in a weird sorta way
08:35 PM MacGalempsy: www.beverlyhillscarclub.com
08:35 PM MacGalempsy: sweet site
08:35 PM malcom2073: Psh.
08:36 PM XXCoder: interesting https://hackaday.com/2017/03/03/powering-a-laptop-with-supercapacitors/
08:36 PM MacGalempsy: its a used car sales site.
08:36 PM malcom2073: XXCoder: We use a set of supercaps on our systems at work as a battery backup. If power fails, it allows the computers to run for a minute or two to shut down
08:36 PM MacGalempsy: they have like 30 pics or just about every angle
08:37 PM XXCoder: mal ya caps still not that good
08:37 PM malcom2073: They're maintainence free, no worries about vibration, charging circuits, or temperature, which is why we use them rather than say, SLA's
08:38 PM malcom2073: It's a safety system on robots: If say... one of the system batteries fails, the caps provide power for the computers to bring the robot to a halt, lock it down safe, then shut down
08:38 PM XXCoder: but very low power per sq area
08:38 PM malcom2073: Yep
08:39 PM XXCoder: ultracaps is getting there but slowly.
08:39 PM malcom2073: Yeah, I don't recall offhand how many farads they are
08:39 PM XXCoder: 2,000 irrc
08:39 PM malcom2073: no I mean ours
08:39 PM XXCoder: oh
08:39 PM malcom2073: You can get 10-50kF ones now
08:39 PM XXCoder: dang my data is old
08:39 PM malcom2073: I think the bigger they are, the higher the ESR though
08:40 PM XXCoder: been years since last research, always wanted cap flashlight lol
08:40 PM XXCoder: ESR?
08:40 PM malcom2073: equiv. series resistance
08:40 PM malcom2073: internal resistance asically
08:40 PM malcom2073: limits how fast it can charge/discharge
08:40 PM XXCoder: interesting
08:40 PM XXCoder: I read about new capactor that can power phone for a week
08:40 PM malcom2073: I love the idea of instant charge slow discharge devices
08:40 PM XXCoder: but I think its bs
08:41 PM malcom2073: Maybe an old nokia :-P
08:41 PM XXCoder: said charges in minutes, isnt it need tons volts
08:41 PM XXCoder: nah modern
08:41 PM XXCoder: pictured object is quite small
08:41 PM XXCoder: 1/4 area as my phone battery
08:41 PM malcom2073: Sounds too good to be true, that's uh
08:42 PM malcom2073: Your average phone battery is what, 3200mAh at 4.6V?
08:43 PM XXCoder: mine is 2800 mAh. 3.8v
08:44 PM gregcnc: LiIon is 3.7 nom., 4.2V charge
08:45 PM malcom2073: That's 40k farads XXCoder
08:45 PM malcom2073: So... entirely possible?
08:45 PM Wolf_: 4.6v might be right for some samsungs
08:45 PM XXCoder: mal caps its possible, for one that looks like just one gram? dunno
08:45 PM XXCoder: mine is older s4
08:46 PM Wolf_: I mean the ones that vent with fire
08:46 PM XXCoder: ah the pant firestarter edition s7 note
08:46 PM connor_goodwolf: what's the go to CNC controller software?
08:47 PM Wolf_: for?
08:47 PM malcom2073: linuxcnc!
08:47 PM connor_goodwolf: for windows? :)
08:47 PM XXCoder: linuxcnc!
08:47 PM XXCoder: (after replacing os)
08:47 PM Wolf_: ^
08:47 PM connor_goodwolf: :|
08:47 PM connor_goodwolf: nyet
08:47 PM malcom2073: connor_goodwolf: There is no "go-to" for windows
08:47 PM Wolf_: live cd, replace windows
08:47 PM XXCoder: uhh theres tons of mach3 shit
08:47 PM connor_goodwolf: need just G-Code CNC software
08:47 PM malcom2073: Mach3 works if you don't care that it doesn't always work
08:48 PM malcom2073: I don't trust it as far as I can throw it, so if you ever do any work you can't afford to do twice, thrice even, don't use it :-P
08:48 PM Wolf_: you need to narrow your query down, thats like saying I need a picture of sky
08:48 PM connor_goodwolf: https://github.com/pknoe3lh/cncgcodecontroller
08:48 PM connor_goodwolf: I guess I'll just try that
08:48 PM XXCoder: not one I was talking about but pretty cool http://fortune.com/2016/02/09/smartphone-fuel-cell-battery/
08:48 PM Wolf_: you need something to make g-code, or send g-code or read g-code?
08:49 PM XXCoder: yeah for cam side windows is better
08:49 PM XXCoder: sadly
08:50 PM Wolf_: pronterface and repetier host both work on windows
08:50 PM XXCoder: foinally found it!
08:50 PM malcom2073: connor_goodwolf: That's not a controller, that's a gcode sender
08:50 PM XXCoder: https://phys.org/news/2016-11-seconds-scientists-closer-reality.html
08:50 PM connor_goodwolf: I just need a host
08:50 PM Wolf_: to control what
08:50 PM XXCoder: I use pronterface for 3d printing
08:50 PM Wolf_: how
08:50 PM connor_goodwolf: forgive me, I'm exhausted
08:51 PM malcom2073: don't CNC drunk or tired :)
08:52 PM connor_goodwolf: nevermind
08:52 PM connor_goodwolf: I just needed a GRBL controller app
08:52 PM connor_goodwolf: I'll try Candle
08:52 PM Wolf_: laser web + smoothie board works for CNC control on windows
08:52 PM Wolf_: but only useful if you are driving a laser
08:52 PM Wolf_: also works with GRBL
08:52 PM XXCoder: so malcom2073 what ya think of that supposely battery
08:53 PM Wolf_: but yeah, GRBL is the CNC controller, you just need something to send g-code to it
08:53 PM connor_goodwolf: I've a laser attachment for it too
08:54 PM Wolf_: >50w?
08:54 PM malcom2073: XXCoder: I think super/ultra/whatever caps are awesome, it's gona be exciting
08:54 PM malcom2073: connor_goodwolf: Make sure you were eye protection.
08:54 PM Wolf_: waiting for my damn quote for my 100w tube and psu still
08:54 PM malcom2073: Lasers will destroy your eyes without you even knowing it
08:54 PM XXCoder: mal did you read link above?
08:54 PM malcom2073: Oh XXCoder, I had missed it
08:54 PM Wolf_: damn Aliexpress
08:54 PM XXCoder: https://phys.org/news/2016-11-seconds-scientists-closer-reality.html
08:54 PM malcom2073: Ah fuel cell, yeah I've seen those
08:54 PM connor_goodwolf: malcom2073: why would I do that? I want to go blind.
08:55 PM XXCoder: no, later one after that lol
08:55 PM malcom2073: connor_goodwolf: There are less painful ways to go blind
08:55 PM Wolf_: Do not look in to laser with remaining eye
08:55 PM XXCoder: mal thats why if I get laser machine i would enclose it. I dont have enough senses to just lose one careless.
08:55 PM malcom2073: +1
08:56 PM connor_goodwolf: Wolf_: lulz
08:56 PM Wolf_: web cam on the laser machine
08:56 PM malcom2073: Wolf_: We have lasers at my work, and the laser guy has a sign on his door that says that
08:56 PM Wolf_: then you don’t need to get near it to see if its on fire either
08:57 PM malcom2073: to see that it's on fire, not if
08:57 PM Wolf_: also it cant poke your eye out via the web cam feed
08:57 PM XXCoder: webcams good idea yeah
08:58 PM XXCoder: dont look at laser with remaining webcam dont sound as bad as eye one heh
08:58 PM Wolf_: I’m thinking about getting another one of them 5mm webcams and hooking it to the side of the laser head =)
08:59 PM Wolf_: or just use the one I have already, like 45’ lead on it
08:59 PM Wolf_: I might need to get some 80/20 from ya malcom2073
09:00 PM roycroft: i stocked up on bulk spices when i went to market today
09:00 PM roycroft: i just finished filling all the spice jars
09:00 PM roycroft: and now i can't stop sneezing
09:00 PM malcom2073: Wolf_: Sure!
09:00 PM XXCoder: mal you has 80/20 store?
09:00 PM malcom2073: XXCoder: Nah, but I got a bunch of it
09:00 PM XXCoder: oh close enough eh
09:00 PM roycroft: you are a hoarder
09:00 PM Wolf_: I need to see what size THK rails I have first
09:01 PM XXCoder: I was thinking about using 2020s to make case for my cnc machine electrics
09:01 PM malcom2073: https://images.craigslist.org/00k0k_4xpqoVcLNiM_1200x900.jpg
09:01 PM malcom2073: Wolf_: I got rails too :)
09:01 PM malcom2073: Want to buy a 5x10 router setup? :-D
09:01 PM XXCoder: lol make GIANT cnc rputer with those, uncut
09:01 PM malcom2073: XXCoder: 12ft each, I was going to
09:02 PM malcom2073: 12ft by 6ft frame
09:04 PM XXCoder: what happened?
09:04 PM malcom2073: XXCoder: Wolf_ Might buy it from me :-P
09:04 PM Wolf_: what type of rail ?
09:05 PM Wolf_: 5x 10 is almost what i wanted to do for my CNC plasma
09:05 PM malcom2073: Wolf_: two 2.6mm 30mm squarerails, two 0.9mm square rails (intended to be butted against for 3.5m), two 30mm 5ft square rails. A german brand, not thk though
09:05 PM Wolf_: wanted 5.5’x10.5” cutting area
09:06 PM Wolf_: hmm get me some pics =)
09:06 PM malcom2073: Will do heh
09:07 PM Wolf_: 80/20 I won’t need much of, only doing a 1500mm x 900mm or something of the sort
09:07 PM roycroft: yes, if that was not purchased for a specific project/production run it officially qualifies as a hoard
09:07 PM Wolf_: for the laser
09:07 PM XXCoder: telsa battery teardown https://youtu.be/NpSrHZnCi-A
09:08 PM Wolf_: tells battery teardown, just vape batteries =P
09:08 PM malcom2073: Heh
09:09 PM malcom2073: Wolf_: I'm looking to get like $1500 for the rails just fyi
09:09 PM malcom2073: You could make a 5x10 aluminum router with them drails heh
09:09 PM malcom2073: May be overkill for you
09:09 PM Wolf_: probably
09:10 PM Wolf_: hell my THK stuff is overkill for laser cutter
09:10 PM malcom2073: Heh
09:10 PM Wolf_: I did want to put a drill head on the plasma table tho
09:10 PM malcom2073: Nice
09:11 PM Wolf_: be nice to have it spot drill for mag drill follow up
09:12 PM malcom2073: Indeed
09:13 PM Wolf_: I have too many projects lol
09:13 PM malcom2073: So take one project off my hands and let it be yours :-D HAH
09:13 PM Wolf_: but the laser cutter seems like a quick easy build
09:14 PM XXCoder: make it able to do 10,000 ipm
09:16 PM Wolf_: 24v psu, 3 steppers, X5 GT smoothie board, 3 wires to the laser psu, chiller and vent fan, 3 mirrors, focus lens and a combiner lens for sighting laser…
09:16 PM Wolf_: and a big ass box
09:16 PM malcom2073: I got some DC servos too if you want :-D
09:16 PM malcom2073: And some random 240V AC ones
09:16 PM Wolf_: lol
09:16 PM malcom2073: (Gotta try)
09:17 PM Wolf_: should just build the cnc router and sell it for $$$$$
09:17 PM malcom2073: Thought about it, could probably sell it for $10k up and running if I built it nice like I planned
09:18 PM malcom2073: 5ft 4th axis on the end and all
09:20 PM Wolf_: lol
09:21 PM malcom2073: I was going to build a vertical router
09:21 PM malcom2073: no room for it flat out
09:21 PM Wolf_: I also need to find a sign shop that will sell me some of that aluminum/plastic composite stuff
09:22 PM jym: Wolf_: ow much you need?
09:22 PM jym: how*
09:22 PM malcom2073: That's what I wanted the router for: making signs
09:22 PM malcom2073: and cabinet doors
09:22 PM malcom2073: figured I could make beer money that way
09:22 PM Wolf_: about the size of the laser machine lol
09:22 PM jym: Wolf_: typically 24" sheets,
09:23 PM Wolf_: bigger shop might have 4x8
09:23 PM Wolf_: or 5x10
09:23 PM jym: That is from the wholesale houses
09:23 PM jym: whay do you want engravable plastic for?
09:24 PM jym: just to skin a laser?
09:24 PM Wolf_: the signabond or w/e its call, yeah to skin the laser machine
09:25 PM jym: Wolf_: and it's fiber reenforced... http://www.homedepot.com/p/1-16-in-x-4-ft-x-8-ft-Plastic-Panel-63003/202090190
09:26 PM jym: Wolf_: and trim pieces if you are so inclined http://www.homedepot.com/p/855-1-4-in-x-1-3-8-in-x-8-ft-PVC-Composite-White-FRP-Divider-Moulding-0085508011/100573218
09:26 PM Wolf_: was looking for the aluminum skinned plastic, so the laser won’t punch through it lol
09:26 PM Wolf_: http://www.globalsignproducts.com/signabond_lite.html
09:27 PM jym: Well, you really don't want a REFLECTIVE surface
09:27 PM malcom2073: Aluminum isn't reflective to some frequencies of light
09:27 PM Wolf_: yeah, just slap matt or chalkboard paint on it
09:28 PM Wolf_: after some test shots on a piece of the stuff
09:29 PM jym: most skins on lasers are poweder coated sheet metal
09:30 PM Wolf_: and I would rather have the laser bouncing around the inside of the box vs setting something on fire on the other side of the shop
09:30 PM jym: the laser is not going to be very strong past 6"
09:30 PM jym: Pre colimator that is
09:31 PM Wolf_: I’ll probably test that when I get the tube and psu lol
09:32 PM jym: whic you could video that =)
09:32 PM jym: wish*
09:32 PM Wolf_: I will :)
09:33 PM Wolf_: shoot some scrap drywall from 10 feet or something with 100w tube
09:33 PM jym: I mena video the beam itself
09:33 PM Wolf_: oh yeah, fog machine? lol
09:34 PM Wolf_: and good laser proof glasses...
09:35 PM jym: Wolf_: make sure they cover the SIDES
09:35 PM Wolf_: yeah
09:38 PM Wolf_: I guess I could just get the sheet metal and make all the panels and get them powder coated
09:59 PM jym: that's what we used to do; pre-shape and drill them,then use 1/4"-20 button-head hex screw to attatch them to the frame
10:00 PM jym: Wolf_: just design them to you can work on the laser easily
10:01 PM Wolf_: yeah, I was actually planning on a 1” square tube frame welded up for the box
10:01 PM Wolf_: tube and gantry rails mounted on 80/20 frame inside of the box, with all the panels removable
10:02 PM jym: Wolf_: consider having an inner secion of frame for a backerer panel to mount electronics to, as well as a sperate area for the tube and water lines.
10:02 PM jym: We used to use 1/8" aluminum plate for that
10:02 PM Wolf_: yeah, also designing it so I can take the whole back off with the tube still in it
10:03 PM Wolf_: and what electronics
10:03 PM jym: you'r enot going to have a control panel?
10:03 PM jym: no pump blower electrical controls?
10:04 PM jym: no safety interlock switches ?
10:04 PM jym: no lighting in the cabinet?
10:04 PM Wolf_: one control board with 4 stepper drivers on it, 24v psu, laser psu, 2 lcd control panels and 2 ssr and a air valve
10:04 PM jym: well all that has to mount to soemthing
10:05 PM Wolf_: 24v>12v dc-dc and a rocker for the 5m of led lighting lol
10:05 PM jym: and you REALLY should have interlocks
10:05 PM Wolf_: yeah, door switch
10:05 PM jym: plural, multiple opens
10:05 PM jym: and make the the work area pass-thru for long sheets
10:06 PM Wolf_: thats a given
10:06 PM jym: so there's TWO interlocks right there, plus for the laser door itself
10:07 PM Wolf_: I think thats more interlocks then the red or blue boxes on ebay
10:07 PM jym: Nope, it's the only legal way they can import them into the US
10:08 PM jym: per FDA regulations
10:08 PM Wolf_: oh, no they screw the laser tube bay shut
10:08 PM jym: some do, some have latches
10:08 PM Wolf_: yeah, latches on the pass doors
10:08 PM jym: mine has latches ont he laser door
10:09 PM jym: but Mine is US, not china laser.
10:09 PM Wolf_: I was going to make mine open up for the pass doors
10:10 PM Wolf_: I am putting a interlock on the main door, latch the tube bay and the pass doors
10:11 PM Wolf_: control stuff bay I was going to wall off from the cutting area + use it as part of the incoming air duct
10:20 PM jym: Um, you don't want to necesarily have laser air going thru electronics area. You'll get all kinds of crap/dust in there.
10:20 PM Wolf_: incoming air path, from the room, w/ pre filter
10:21 PM Wolf_: exhaust down at the bottom of the machine at 750cfm
10:21 PM jym: at what SP ?
10:21 PM Wolf_: no idea lol
10:22 PM jym: heh
10:22 PM jym: Mine is 900CFM@6" SP
10:22 PM jym: but whatever works for you
10:23 PM Wolf_: lol says 190W 1.75A 2450rpm 8” 740 CFM…
10:23 PM jym: also be sure to have a way to shutdown everything in case of fire, including airflow (like using an electric gate valve)
10:23 PM Wolf_: no other specs
10:24 PM jym: 8" is SP
10:24 PM XXCoder: wow https://fossbytes.com/goodenough-solid-state-battery-glass-electrolyte/
10:24 PM jym: that's fine
10:24 PM jym: Wolf_: it's not the CFM as much as the SP
10:25 PM Wolf_: yeah, air assist is using real electronic valves from guy that buys out auction stuff
10:25 PM jym: valves? It's just a pump
10:26 PM Wolf_: http://a.co/9SvmRXJ fan, pot growers seem to like it lol
10:26 PM Wolf_: I was just going to use shop air
10:27 PM XXCoder: reminds me of that weird new what seems to be dehumifier fan attached to new cnc machines at work
10:27 PM XXCoder: it drains stright to coolant tank.
10:27 PM Wolf_: well filtered shop air...
10:28 PM XXCoder: it sucks air from interior of machine
10:28 PM XXCoder: so yeah dunno
10:29 PM XXCoder: looks like very powerful duct fan
10:29 PM XXCoder: considering machine is little larger than arcade machine its bit puzzling
10:29 PM jym: nope, they dont have a lot of SP
10:30 PM XXCoder: anyone knows why its there?
10:31 PM jym: http://www.harborfreight.com/13-gallon-industrial-portable-dust-collector-31810.html
10:32 PM XXCoder: looks like radiohack is dying once again
10:32 PM Wolf_: SP suction pressure?
10:32 PM roycroft: that's not a particularly good dust collector
10:32 PM roycroft: but you can convert it to two stage and it will be better
10:33 PM jym: Wolf_: SP = Static Pressure
10:33 PM Wolf_: oh right
10:34 PM roycroft: http://www.harborfreight.com/2-hp-industrial-5-micron-dust-collector-97869.html
10:34 PM roycroft: or get that one
10:34 PM jym: roycroft: not for "dust" , for laser
10:34 PM roycroft: oh
10:34 PM roycroft: so for a laser you're just using it to move air?
10:34 PM jym: Wolf_: 537CFM@7.2" SP http://www.grizzly.com/products/G1163P
10:35 PM Wolf_: I could see needing high SP if the box was almost totally sealed, but I was planning on intake being the same size as the out going air
10:35 PM jym: roycroft: air, smoke, vaporized plastics,
10:36 PM jym: Wolf_: You would want HIGHER SP if the box wasn't air tight
10:36 PM jym: Wolf_: You really dont want smoke getting to the optics.
10:37 PM Wolf_: that I know
10:37 PM jym: Wolf_: else use a bigger inline fan
10:37 PM jym: lower rpm = higher SP
10:37 PM jym: but those inline fans barely get an inch
10:38 PM Wolf_: stuff on optics = need new when they break
10:38 PM jym: they just move air, no pressure behind it
10:38 PM jym: the site that has data is offline or I would show you
10:38 PM Wolf_: I kinda get it
10:39 PM Wolf_: pretty much know if smoke doesn’t go = bad
10:39 PM jym: http://www.hvacquick.com/products/residential/Fans/Hydroponics-Fans/AirScape-Inline-Hydroponics-Duty-Fans-645-900-cfm
10:40 PM jym: the 10" is 645CFM@2.9"
10:40 PM jym: and that's the 10", not like the one you were looking at.
10:41 PM jym: and only if you lower it to 90CFM
10:41 PM jym: ...do you get the 2.9"
10:41 PM XXCoder: weird. just read news that someone handling airplane baggage was stealing guns and putting pot in
10:41 PM jym: at 630CFM you only get 0.4" SP
10:41 PM jym: XXCoder: nice
10:42 PM XXCoder: dont own guns and dont need pot
10:42 PM jym: Wolf_: Teh 10" inline fan: http://www.hvacquick.com/products/residential/Fans/Hydroponics-Fans/AirScape-Inline-Hydroponics-Duty-Fans-645-900-cfm
10:42 PM Wolf_: … wtf type of HVAC site has no air handler replacment fans
10:42 PM XXCoder: jym: thats similiar to what I saw
10:43 PM MacGalempsy: loss of circulation...dang...
10:43 PM jym: Wolf_: compare a 20" box fan with a 20" whole house fan to kinda understand what I mena
10:43 PM Wolf_: yeah, well I have a fan unit out of a HVAC heat pump also
10:44 PM jym: Wolf_: I'm not saying don't, just harding you the explosives, and the match.
10:44 PM jym: handing*
10:44 PM Wolf_: 20 x 18” cage type, probably 3/4 hp
10:45 PM jym: Wolf_: ...and running like hell too
10:45 PM jym: Wolf_: You COULD do multiple fans too
10:45 PM jym: of those inline things
10:46 PM Wolf_: yeah, try the thing I have now in the shop laying around, if it works yay, if no, get something bigger, or add more lol
10:46 PM jym: fair enough =)
10:47 PM Wolf_: its big enough that it needs a starter cap =)
10:47 PM jym: Wolf_: ppl are using these for air assist https://www.amazon.com/EcoPlus-728450-Single-Outlet-Commercial/dp/B002JLJC0W
10:48 PM jym: Wolf_: like the 30W
10:48 PM jym: iirc
10:49 PM jym: Wolf_: no valves, just on/off =)
10:50 PM jym: Wolf_: are pretty quiet too
10:50 PM Wolf_: the thing I’m talking about is probably 1950 cfm @ 0.5 wc, so duct it down some, should drop some cfm but gain some SP
10:51 PM Wolf_: I’ve heard so much bad stuff about them as air puffers
10:51 PM Wolf_: how about a air brush compressor?
10:53 PM jym: not enough continous air
10:53 PM Wolf_: currently this project is partly a challenge to build a good system cheap as possible lol
10:54 PM jym: youcan try it
10:55 PM Wolf_: I think i’ll go with shop air + surplus reg/filter/valve which i can get for less then normal reg cost =)
10:56 PM XXCoder: why just blow on it ;)
10:56 PM Wolf_: only thing I’m missing from the puzzle is how to setup the Z axis bed lift
10:57 PM XXCoder: laser right?
10:57 PM Wolf_: yeah
10:57 PM XXCoder: whats wrong with normal router style z assembly?
10:58 PM XXCoder: but same time low clearance maybe hmm
10:58 PM Wolf_: can’t move the head up/down, it has a mirror at the top of it
10:58 PM XXCoder: ahh
10:59 PM Wolf_: mirror on the end of the gantry on the y axis shoots the beam to the head on the x
11:00 PM XXCoder: 4 ballscrews probably too complex
11:00 PM XXCoder: one per leg
11:01 PM Wolf_: I was thinking 4 screws, #25 chain and stepper to spin them all
11:01 PM Wolf_: ball screw is overkill
11:03 PM Wolf_: http://www.lightobject.com/Power-table-bed-kit-for-P530-500x300-P1010.aspx
11:03 PM Wolf_: minus the wtf price
11:03 PM XXCoder: dont seem very expensive till I saw sizes
11:03 PM XXCoder: its quite small
11:07 PM Wolf_: yeah, I could actually build part of that right in to the bottom of the 80/20 that will be holding the Y axis rails
11:11 PM XXCoder: wonder if cn go right inside bigger 3030 beams
11:11 PM XXCoder: make it "screw itself up" out of bottom frame? heh
11:12 PM station: need some help choosing a spindel, do I need speedcontroll?
11:12 PM XXCoder: well it depends
11:12 PM station: https://www.aliexpress.com/item/500W-PCB-WS55-220-brushless-spindle-motor-with-a-dedicated-controller-with-ER16DIY-CNC-engraving-machine/32711662860.html?
11:12 PM XXCoder: theres manual knob speed control
11:12 PM XXCoder: pwm or pfd
11:12 PM station: https://www.aliexpress.com/item/Best-cnc-spindle-500W-air-cooled-0-5kw-milling-Motor-spindle-speed-power-converter-52mm-clamp/32757756627.html?
11:13 PM XXCoder: make sure its diameter you need
11:13 PM station: diameter for the bits …
11:13 PM XXCoder: I wanted to buy one that was 57mm but later found out that out and bought other one at 52mm it needed
11:13 PM XXCoder: no spindle itself
11:15 PM station: you refere to the bit chuck size
11:16 PM XXCoder: no the spindle diameter itself. not chuck or collet so on
11:16 PM Wolf_: motor diameter
11:16 PM Wolf_: hard to mount if it won’t fit on the machine
11:16 PM XXCoder: because 52mm and 57mm spindles look pretty much same
11:16 PM XXCoder: like I said I was pretty close to making that mistake so warning for you to be sure on diameter
11:17 PM station: aaa for the clamp to fasten it to the machine …
11:17 PM XXCoder: indeed
11:17 PM Wolf_: Diameter: around the middle part of the motor cover 57MM 55MM < your first link
11:17 PM Wolf_: 2nd link is a 52mm
11:18 PM station: besides that is there anything to lean more to the first or second one
11:19 PM XXCoder: first might be PWM type
11:19 PM XXCoder: second has removable bushinbgs
11:20 PM XXCoder: controller is also unknown
11:20 PM XXCoder: I'm just guessing it is also pwm
11:20 PM Wolf_: 2nd isn’t BL motor
11:23 PM station: so the first one …
11:24 PM Wolf_: being bl/brushed really up to you...
11:24 PM station: my hopes are to get to some degree barock decorated furniture
11:25 PM station: with a selfbuild CNC
11:29 PM XXCoder: station: size of machine?
11:35 PM station: i hope 1m by 2m the 2 m may be with steel pipe fastend to the board
11:35 PM XXCoder: 1m by 2m. what material would it mostly cut?
11:36 PM station: wood mdf
11:36 PM jym: packing peanuts =)
11:36 PM XXCoder: either would work for you really if you are also designing clamp for it (or buying it elsewhere)
11:37 PM XXCoder: though latter I dunno it has bushings
11:39 PM station: bushing aren't as good as bearings?
11:39 PM station: Im jumping a little into the unknown, even thow I read a lot
11:39 PM XXCoder: both has bearings
11:39 PM XXCoder: bushings is part of spindle that does wear with age
11:40 PM XXCoder: theres larger but no bushings spindle
11:40 PM Wolf_: brushes?
11:41 PM XXCoder: ah yes brushes
11:43 PM XXCoder: https://www.amazon.com/SUNWIN-Spindle-Brushless-Engraving-Machine/dp/B00QUIBBFO interesting
11:43 PM XXCoder: though it dont even say what diameter it is
11:43 PM station: and with brushless can there be a longer life expectancy with the driver or is it just relocating the problem from the brush to the driver
11:44 PM steve_stallings is now known as steves_loggind
11:44 PM XXCoder: from my research while ago its better life for brushless though I may be wrong. Wolf_ ?
11:44 PM Wolf_: BL has no brushes to wear
11:45 PM Wolf_: also kinda better for high speed
11:46 PM station: and drivers hold up???
11:47 PM Wolf_: as well as most really cheap china electronics
11:47 PM Wolf_: might run for years, or 5 mins
11:47 PM XXCoder: yeah go chineseium and you risk it. cheap though
11:47 PM XXCoder: just make sure driver is one you can buy seperately
