01:09 AM fragalot: hi
01:12 AM XXCoder: yo
01:17 AM XXCoder: not bad! tapping station https://www.youtube.com/watch?v=OfzXrN5jVig
01:19 AM Bryan is now known as Guest28149
02:09 AM Deejay: moin
02:11 AM gloops: https://www.youtube.com/watch?v=2ZVmKiehGnU&feature=youtu.be interesting variation of 4th axis on router
02:14 AM XXCoder: yah
02:14 AM Deejay: hehe cool
02:14 AM XXCoder: looks 3d printed
02:15 AM gloops: yeah theyll all be making them
02:17 AM MarcelineVQ: up until the teeth fill up with chips
02:17 AM gloops: r&p wont be very accurate for the rotary, maybe good enough for wood though
02:20 AM CaptHindsight: two third axes to be anal
02:23 AM gloops: when i do mine, im not having it on the main router table, ive got an old quality wood lathe, so i plan on having it as a 4 axis router, but also available for manual turning when i want
02:25 AM gloops: if the spindle/z axis travels above it wont be in the way at all for manual work
02:52 AM miss0r: Mornin'
02:53 AM XXCoder: yo
02:54 AM * miss0r is about to design and build a floating tapping head for the cnc
02:54 AM XXCoder: nice
02:55 AM miss0r: perhaps it will be :)
02:55 AM * miss0r is just brainstorming at the moment
03:09 AM miss0r: its occuring to me that this is one of those builds that will take days to complete, if I end up going abe shit about it. Grinding everything ect...
03:09 AM miss0r: and I might just do that :D
03:12 AM gloops: note from daughter seems to have put paid to my plans today - shes home from uni doing some part time work at the local wetherspoons 'dont make any noise tommorrow didnt get in while late need a long lie in' ffs
03:14 AM miss0r: "My house, my rules; now mow the lawn!"
03:19 AM MarcelineVQ: spare the rod
03:19 AM MarcelineVQ: Do whatever you'd be doing anyway :>
03:20 AM miss0r: "WTF ARE YOU DOING!?" "What I do every saturday morning; Reducing bricks to rubble with a jackhammer" :D
03:21 AM MarcelineVQ: daily air-file exercise keeps the wrist supple don't you know
03:21 AM miss0r: :]
03:24 AM miss0r: bah! Looking for some wire to use for my mesa build. I'm thinking 0.35mm^2.. but it would seem that is roughly 10x as expensive as 0.5mm wire...
03:24 AM miss0r: (yeah, I didn't realy muster the motivation to get started on the floating head build) :D
03:50 AM XXCoder: miss0r: nike said it right
03:59 AM miss0r: yup
03:59 AM XXCoder: man some days I really miss being able to see stars
04:00 AM XXCoder: BIG downside to cities is light pollution
04:00 AM miss0r: yeah
04:01 AM miss0r: I live on the border of farmland, I can see stars :)
04:01 AM miss0r: well.. not right now, as it is 11:00
04:01 AM XXCoder: it would take me 2 hour drive minium to go to maganate 2 darkness
04:01 AM XXCoder: thats minium to see milky way
04:01 AM miss0r: damn
04:01 AM miss0r: I'd get crazy
04:02 AM XXCoder: http://www.jshine.net/astronomy/dark_sky/
04:02 AM XXCoder: east side got it worse
04:03 AM miss0r: Sadly, this does not work outside of the US
04:03 AM XXCoder: yeah too bad the dark sky finder dont have anyone doing any work outside usa
04:04 AM XXCoder: 2 hours 14 min for one route to darkest sky
04:05 AM miss0r: yeah
04:05 AM XXCoder: it covers canada and mexico
04:05 AM miss0r: Would any of you know if it is possible to use one of those generic USB cnc controllers(sold for use with Mach3) with linux cnc?
04:06 AM XXCoder: theres few pins for darkness but map isnt showung night chart
04:06 AM XXCoder: what country you in?
04:06 AM miss0r: Denmark
04:06 AM XXCoder: theres 2 pins there
04:07 AM XXCoder: muldbjerg and unnamed site 5558
04:08 AM XXCoder: unnamed is at odense
04:08 AM miss0r: When looking at a light pollution map of Denmark, it does not look at that good where I live, actualy :)
04:09 AM XXCoder: does it say what magagate light your places at?
04:09 AM XXCoder: https://sfct.org/wp-content/uploads/2018/04/light-pollution-levels_small.jpg
04:09 AM XXCoder: mines at 8-7 depends where I am in tacoma
04:09 AM XXCoder: at vancouver I used to have 6
04:10 AM miss0r: ahh the bortle value.. I saw that somewhere, hang on
04:10 AM miss0r: 2.7
04:11 AM miss0r: so somewhere between average dark sky and rural
04:11 AM XXCoder: someday I will have vacation to see 1 level site. timing is HARD because clouds could happen
04:11 AM miss0r: yeah
04:11 AM MarcelineVQ: shucks buster, take the chance out of it, save up for a space launch
04:12 AM XXCoder: lol that'd be basically 0 light level
04:12 AM XXCoder: zero light pollution, zero sky inference
04:12 AM miss0r: yeah, no "chance" involved in traveling to space
04:12 AM MarcelineVQ: no chance of cloudy weather
04:12 AM XXCoder: there is a VASTLY cheaper way though
04:12 AM XXCoder: plane.
04:12 AM XXCoder: charted not commerical
04:13 AM XXCoder: just couple hours flight off coast into very dark ocean skies, above clouds
04:13 AM XXCoder: sky is thinner also
04:13 AM miss0r: We used to do miletary exercises in a place that is level 1
04:13 AM miss0r: that place was DARK at night :)
04:14 AM XXCoder: if I was made from money, I would create a clear top plane, limited seating plenty of spaces to walk around and chat
04:14 AM XXCoder: it'd be large commerical plane, converted so it could fly for hours. parties!
04:15 AM XXCoder: large kitchen, space to chat and stare at skies, and full size restrooms. none of those barely fit in crap
04:15 AM miss0r: but the quite kind, about looking at the sky, not playing beer bong
04:15 AM XXCoder: more leg space than president plane
04:16 AM XXCoder: indeed
04:17 AM XXCoder: only flaw is skywatcher party plane would cost quite a bit
04:17 AM XXCoder: probably double or more than regular plane cost
04:17 AM MarcelineVQ: If money isn't a barrier I'd make a tower into space and stand on top of the planet, alone but for the endless life below
04:18 AM MarcelineVQ: trace my fingers around and pretend I'm swiriling the hurricanes
04:18 AM XXCoder: marc there is conceptal tower design that bypasses physics limition of materal
04:18 AM XXCoder: its dynimatic structural support tower, basicallt it uses impacts from base to keep upwards, using tubes and such
04:19 AM XXCoder: makes tower MUCH more stiff than any mere mortal mineral building can be
04:20 AM miss0r: You gotta love science
04:20 AM XXCoder: theres also concept using similiar idea to build launcher arc, thats miles high and crosses many miles
04:20 AM XXCoder: it uses water or any media being pumped very very fast so momenium prevents structure from falling
04:21 AM MarcelineVQ: these sound like amazing ideas for making videos of spectacular momentary failures
04:21 AM XXCoder: yeah
04:21 AM miss0r: yeah.. "what does this button do"
04:21 AM XXCoder: there is another one, one of later structures, its a ring around entire world. it does NOT rotate so people can walk on it
04:22 AM XXCoder: 80% gravity at that distance from earth
04:22 AM XXCoder: it uses 2 spinning very thick cables to keep up
04:22 AM XXCoder: one is spinning other way
04:23 AM XXCoder: so such structure can simply launch something by pushing it to orbial speeds
04:23 AM MarcelineVQ: so it does rotate, it just rotates with the earth?
04:23 AM XXCoder: it cant simply drop it as it would fall into earth lol
04:23 AM XXCoder: yeah, if it didnt have dynimatic support it would fall into earth
04:23 AM MarcelineVQ: Yes it would
04:24 AM MarcelineVQ: even then it probably would, given how good humans tend to be overall at engineering :>
04:24 AM XXCoder: 2 thick cables spinning, and use magnets to keep it up to speed it should last forever since it has no physical contact
04:24 AM XXCoder: solar panels to keep it powered forever
04:24 AM MarcelineVQ: no contact? not sure what you're talking about with cables
04:24 AM XXCoder: quite good most times, we can miss some details though
04:25 AM XXCoder: MarcelineVQ: basically picture it this way
04:25 AM XXCoder: its a pair of tubes, with coverings and cable going all way around earth
04:26 AM XXCoder: ignoring any extra structure such as fuel depots, humans homes work spaces etc, that bare sturcture is all we need for this example
04:26 AM MarcelineVQ: it's the cable part I'm unclear about
04:26 AM XXCoder: cable is held in place inside tube by magnets that can also spin cable up
04:26 AM XXCoder: so when its spinning fast enough, tube can't change shape as long as tube ingeration is intact
04:27 AM XXCoder: so it stays rigid tube
04:27 AM XXCoder: gyro also means it can't change angle
04:28 AM XXCoder: we could opt out of that and use water as spinning media, so its like hose going all way around world
04:28 AM XXCoder: water is moving really fast so hose cant kink or move
04:29 AM XXCoder: of course spinning one would cause tube to move opposite direction
04:30 AM XXCoder: so theres another going other way
04:30 AM XXCoder: bingo, it stays on place and 2 tubes mean its nice and super rigid
04:33 AM XXCoder: MarcelineVQ: https://www.youtube.com/watch?v=ezH1BIqa368
04:34 AM XXCoder: less cluttered one https://www.youtube.com/watch?v=DOSxY0Y46ec you see the two tubes.
04:36 AM XXCoder: the structure to earth have two uses, making ring stay in center, and bringing up and down stuff
04:36 AM MarcelineVQ: Yes it would need such a structure. an orbital ring like you're describing that uses gyroscopic action is free to move along the axis tangent to the disk it describes, in other words without orbital tethers like the ones with elevators in that vid it can just slide away from the planet never to be seen again
04:37 AM XXCoder: yeah I guess it would need to be built offsite first
04:37 AM MarcelineVQ: It will also need a whole of of motors along its entire outside for small corrections of the stucture over time
04:37 AM XXCoder: then lowered into earth then tethered while its in active centering
04:37 AM MarcelineVQ: *whole lot
04:40 AM MarcelineVQ: The most interesting form of this sort of superstructure to me is the ringworld, though a lot of people really like dyson spheres since they don't waste any solar energy. ribbons around suns are cuter than balls
04:42 AM XXCoder: you should watch more issac autur videos
04:42 AM XXCoder: great possibiltes
04:43 AM XXCoder: we could do "dyson sphere" which really is billions of space habs around sun
04:46 AM jthornton: morning
04:47 AM XXCoder: HexaCube: yo
04:51 AM XXCoder: hows your research going HexaCube
04:51 AM HexaCube: slow :P
04:51 AM HexaCube: still looking for a stepper driver i like :D
04:51 AM XXCoder: cool :)
04:51 AM jthornton: what voltage?
04:51 AM HexaCube: 36V or less
04:51 AM HexaCube: I really really like the trinamic stepper drivers because of their features
04:52 AM HexaCube: but they don't offer quite enough voltage (2.2A and the motor is specced for 2.8A)
04:52 AM HexaCube: erm
04:52 AM HexaCube: current, not voltage
04:52 AM * HexaCube still a bit drunk
04:53 AM jthornton: this is the best drive out there for 50v or less https://www.geckodrive.com/g251x.html
04:54 AM HexaCube: why, if I may ask?
04:54 AM XXCoder: as low as $39 but I sont see how
04:54 AM HexaCube: Trinamics are well known for 3d printers, but that's a somewhat different use case, I guess
04:54 AM jthornton: I don't see $39 either
04:54 AM XXCoder: $65.00 As low as $39.00
04:55 AM jthornton: the gecko drives are bullet proof and they morph from 10 micro steps to full steps as the rpm increases so best performance and least vibration
04:55 AM miss0r: In my opinion you can get away with a wide vareity of drivers.. as long as you have a proper controller
04:55 AM MarcelineVQ: gecko's can take a lot of abuse
04:55 AM miss0r: but that being said, I like gecko :)
04:56 AM MarcelineVQ: those are actually cheaper than the last ones I saw too
04:56 AM jthornton: they are a bit higher in price but if you don't want to putz around with drives they are the way to go
04:57 AM miss0r: yeah, they are basically guaranteed to do thy bidding
04:57 AM jthornton: that's the 50v one without a case but has terminals and heat sink
04:58 AM miss0r: bah.. .I'm required to go socialize... see you around
04:58 AM HexaCube: jthornton: I don't mind tinkering with drivers to be quite fair. The TMC drivers have up to 256x microstepping, which is quite cool
04:58 AM HexaCube: aswell as some other *REALLY* nice features
04:58 AM HexaCube: like adjusting motor speed to prevent a stall, detecting a stall
04:58 AM * jthornton wonders where the microstepping myth page was
04:58 AM HexaCube: jthornton: I'm aware about that, but it makes the motors whisper quiet and run very smooth
04:59 AM HexaCube: for a router quiet motors aren't really important, to be fair :P
05:00 AM jthornton: The real compromise is that as you increase the number of microsteps per full step, the incremental torque per microstep drops off drastically. Resolution increases but accuracy actually suffers.
05:02 AM HexaCube: Right, something like that I do remember reading
05:04 AM XXCoder: it doesnt matter for 3d printers up to a point, but milling it matters a whole lot more
05:05 AM XXCoder: much more sideload and such
05:06 AM HexaCube: so I'd actually wanna run with very little microstepping?
05:06 AM XXCoder: no like anything theres a balance
05:06 AM HexaCube: fair enough, I understand
05:06 AM XXCoder: I dont know enough to give more specifics but others here do
05:06 AM XXCoder: my machine I use 8x which seems to work very well when I was cutting wood.
05:07 AM XXCoder: also, I dont care if it sounds like its crunching gravels as long as machine is fine and neighbors dont hear it
05:07 AM jthornton: that's one of the many reasons gecko is a great drive it has 10 micro steps at slow speed and morphs to full steps as the speed increases and the morph point is adjustable
05:07 AM XXCoder: dynimatic microstepping is great way to preserve torque strength yeah
05:08 AM XXCoder: also, 10? odd because thats not power of 2
05:08 AM jthornton: and my steppers run very quiet
05:11 AM HexaCube: jthornton: hmm, why not just stick with 10 micro steps, permanently? Can the serial port not keep up otherwise?
05:12 AM XXCoder: in other words, permently low torque?
05:12 AM jthornton: no it's about having the best torque at full speed the input pulse is 10 microsteps all the time
05:13 AM jthornton: also the morph point is set so the stepper does not make the rattling noise as it crosses some electrical thing
05:14 AM HexaCube: jthornton: but see how quit those motors are? :P https://www.youtube.com/watch?v=UOTd77ctWiw
05:14 AM HexaCube: quiet*
05:17 AM MarcelineVQ: Kinda had to say, person filming didn't make a control sound at the start for comparison
05:17 AM MarcelineVQ: *hard to say
05:17 AM * jthornton thinks 95% of putube videos are crap
05:18 AM HexaCube: https://www.youtube.com/watch?v=bZua6tg_Za0
05:18 AM XXCoder: 90% of anything is crap
05:18 AM HexaCube: comparison to the go-to drivers before the Trinamics became popular :P
05:22 AM HexaCube: but to use the TMCs with the properly sized motors I'd have to make my own drivers essentially
05:22 AM HexaCube: and that's complicated :C
05:22 AM MarcelineVQ: Or not be concerned about noise
05:23 AM HexaCube: well, price is my main concern ;P
05:23 AM jthornton: only 12h:58m:58s of daylight today so the chickens get 1h 2m of extra light
05:24 AM MarcelineVQ: Don't agonize too much, the drivers were the cheapest part of my build by far, it's worth it to spend a bit on them
05:24 AM jthornton: if price is the reason then just get the cheapest one you can find
05:24 AM MarcelineVQ: I probably spent as much on fasteners as drivers :X
05:24 AM HexaCube: https://www.trinamic.com/products/integrated-circuits/details/tmc2160-ta/
05:24 AM HexaCube: that's the IC I'd have to use for nice drivers but... nyeh, I never did any 4 layer board design yada yada yada
05:25 AM MarcelineVQ: If ur gonna make it from scratch you might as well make a dc servo anyway
05:25 AM MarcelineVQ: No sense making a stepper from components with all the ready-made options
05:25 AM MarcelineVQ: or servo for that matter hehe, but if you've the choice to make one or the other..
05:28 AM HexaCube: well it does make sense if it ends up being cheaper
05:28 AM HexaCube: which is quite a possibility, seeing how the Geckos cost 50-60USD each for instance
05:29 AM MarcelineVQ: Value your time HexaCube
05:29 AM HexaCube: but... it'd be a whole new project
05:29 AM HexaCube: eh I have pleeenty time ;P
05:29 AM MarcelineVQ: Even if your time was valued at 10$ an hour it's not worth it to make your own geko
05:30 AM HexaCube: I wish my time was worth that much :P
05:30 AM HexaCube: that'd be more than what I get at work hourly
05:30 AM MarcelineVQ: It is, whether you make that or not
05:31 AM jthornton: and the lights come on and the coop door opens as if by magic :)
05:31 AM HexaCube: who says it is? :P
05:31 AM HexaCube: i mean, I don't see how free time is worth anything really
05:33 AM Tom_L: morning
05:34 AM jthornton: morning
05:36 AM Tom_L: is 'run from line' in the docs somewhere?
05:38 AM XXCoder: hey
05:39 AM jthornton: in the Axis docs yes
05:39 AM jthornton: what were you talking about the other day about run from line?
05:39 AM Tom_L: i just found it mentioned there
05:39 AM Tom_L: do you know when it was introduced to lcnc?
05:40 AM Tom_L: or has it been there all along
05:40 AM jthornton: a long time ago
05:40 AM MarcelineVQ: it is mentioned, though the easier way to use it doesn't seem to be mentioned. which is to right click on the line you want to run and click run from line there
05:40 AM Tom_L: i ran across it by accident is why i wondered if it was in the docs
05:41 AM Tom_L: i thought it was somewhat new, maybe introduced around the time the new TP was added
05:41 AM jthornton: http://linuxcnc.org/docs/2.2/html/gui_axis.html#r1_3_1
05:41 AM jthornton: 1.3.1.14 Set next line
05:41 AM jthornton: at least since 2.2
05:42 AM Tom_L: wow
05:42 AM Tom_L: i never new it was there until lately
05:43 AM Tom_L: do the other GUI support it?
05:43 AM jthornton: dunno
06:48 AM valentin_s: hey, would it be possible to control my huanyang vfd by the rs485 from my 7i96 mesa card directly?
06:55 AM jthornton: how are you making the configuration for your 7i96?
06:55 AM jthornton: just wondering
06:56 AM jthornton: The 7I96 has one RS-422/RS-485 interface available on TB2. This interface is
06:56 AM jthornton: intended for I/O expansion with Mesa SSERIAL devices.
06:56 AM jthornton: then I see this: For 2 wire RS-485 applications, TX+ must be connected to RX+ and TX- must be
06:56 AM jthornton: connected to RX-.
06:57 AM jthornton: anyway when pcw_home wakes up he can answer that
08:34 AM fragalot: Any suggestions on how to get the smell of dead mice out of your coolant tank? :)
08:49 AM Lcvette: hello
08:49 AM gloops: wow that beard would be an issue in a machine shop https://www.facebook.com/InTheWoodsWithPhil/videos/231127270896442/
08:50 AM pink_vampire: fragalot: LOL
08:50 AM gloops: fragalot put some live mice in it
08:50 AM Lcvette: run from line and run from here same thing im guessing?
08:50 AM Lcvette: morning
08:52 AM pink_vampire: you need to run the coolant through enough chips to filter the smell out
08:53 AM pink_vampire: fragalot: ^
08:54 AM fragalot: Lol
08:59 AM fragalot: Add alcohol, light.
09:03 AM syyl_: haha fragalot
09:03 AM syyl_: schaublin in my shop too ;)
09:03 AM syyl_: http://gtwr.de/div/pro_schaublin102_aug_001.jpg
09:04 AM syyl_: once again, a complete rebuild :D
09:10 AM Tom_L: Lcvette yes
09:49 AM fragalot: syyl_: nice :) seems you found the right crowd. :)
09:49 AM fragalot: The alcohol seems to have taken the edge off of the stink. ( I did not actually light it :P)
09:50 AM fragalot: I also just made my first cuts. Really impressed so far!
09:51 AM fragalot: Hogs pretty well considering the size and power available, and the surface looks fantastic with a nice overlapping cross hatch pattern in both x and y
09:52 AM * fragalot = happy
09:52 AM pink_vampire: happy is ok
09:54 AM fragalot_: Coolant pump just tripped the breaker
10:00 AM pink_vampire: is that the coolant for the catting or for the spindle?
10:01 AM HexaCube: why not both :P
10:12 AM fragalot_: pink_vampire Curting
10:12 AM fragalot_: Ffs, cutting
10:14 AM pink_vampire: try to keep the system close
10:14 AM HexaCube: I think our spindles actually are cooled with cutting coolant
10:14 AM fragalot_: It's behind a transformer so the leakage current must be quite high, should be easy to find
10:14 AM HexaCube: the coolant is cooled, too
10:14 AM fragalot_: This spindle is cooled by sheer mass :)
10:25 AM fragalot_: Fixed. Obscene amount of chips in the connector :)
10:34 AM Lcvette: slow today
10:37 AM Lcvette: hey
10:38 AM Lcvette: am i invisible?
10:38 AM pink_vampire: no
10:38 AM pink_vampire: Lcvette:
10:40 AM Lcvette: i can see you
10:40 AM Lcvette: but you are not registering on the irc
10:41 AM pink_vampire: 11:39:53] NickServ [NickServ@services.]: You are already logged in as pink_vampire.
10:45 AM Lcvette: pink_vampire: i cannot see you on my riot.im desktop app but i see you in the web irc app
10:46 AM hazzy-lab: the matrix bridge must be messed up again :(
10:46 AM Lcvette: :(
10:46 AM hazzy-lab: jthornton: I think I found the solution to your setup.py problem, change your package data line to this: package_data={'': ['*.py', '*.ui']},
11:03 AM jthornton: thanks, I'll give that a whirl
12:32 PM _unreal_: This is driving me crazy I dont know where my Rpi CNC HAT IS
12:36 PM gloops: this is the RPI to which we should aspire
12:36 PM gloops: http://www.rpiuk.com/
12:41 PM _unreal_: This sucks I really need those soft 90 flex hdmi and usbc cables
12:41 PM _unreal_: just ordered them last night
12:41 PM _unreal_: till I get those dealing with this LCD is going to be a pain
12:42 PM _unreal_: I dont have a single dirt cheap light duty hdmi cable there all thick and stiff
12:42 PM _unreal_: cables and long body plugs :(
12:44 PM _unreal_: !!! I need an old scsi cable I wonder if I even have one any more
12:44 PM _unreal_: external scsi
12:46 PM _unreal_: @#$@#$ acording to ebay my cnc control had could arrive any time from yesterday to sept18
12:46 PM _unreal_: @#$@#$ acording to ebay my cnc control hat could arrive any time from yesterday to sept18
12:50 PM gloops: lol
12:59 PM gloops: 6 weeks from china
12:59 PM gloops: mine was over 6 weeks, they didnt even post it for 3 weeks
12:59 PM _unreal_: hum
01:00 PM _unreal_: will be nice to start putting stuff together
01:00 PM gloops: plenty of time to get the mechanical side ready
01:00 PM _unreal_: I'm still trying to decide on my monitor setup as far as the BOX to mount everything in
01:00 PM _unreal_: time LOL
01:01 PM _unreal_: !! I may just pull my mounting bracket off today
01:02 PM _unreal_: from my home cnc and mill the Z mount that I have never done.... finally got access to my drill press/xy table in the garage
01:02 PM _unreal_: beel dealing with hurricain irma BS for months now around the house
01:06 PM gloops: well, my building spree should be starting again this week, ive had a boatload of stuff to sort out over the last couple of months, plus acute earache from her indoors
01:17 PM _unreal_: her indoors?
01:26 PM gloops: the mrs
01:30 PM fragalot: he
01:32 PM gloops: evening
01:36 PM _unreal_: There most of my parts are now in a parts box
01:40 PM gloops: what im saying here unreal, it would pay to focus on the mechanical aspect of the build, as well as the control peripherals
01:41 PM gloops: these gadgets are all very well, but first and foremost we need a bulletproof physical build
01:47 PM sensille: is there a dedicated channel for tinyg?
01:52 PM * gloops turns large knob on analogue radio - howling dogs sounds morph into various garbled communications, no tinyg chat detected
01:52 PM pink_vampire: https://www.youtube.com/watch?v=v3811aHWIBA
01:52 PM sensille: i tried the obvious #tinyg, no one there
01:53 PM fragalot: and with ## ?
01:53 PM sensille: same
01:53 PM sensille: it can be mine!
01:54 PM sensille: i'm still thinking about my fpga motion control and had the idea that with 5th order control the math could actually be much easier
01:55 PM sensille: and i think they're doing something similar
02:00 PM syyl_: finaly got the t&c grinder all back together and in a condition that i want it to be :D
02:00 PM syyl_: http://gtwr.de/div/art_kegelsenker_010.jpg
02:00 PM infornography: ello, I connected a hobbycnc EZ to a pc last night and had some issues with missed steps and sometimes the motor would spin in reverse. I maxed out timing settings and it didn't seem to have much effect. I'm thinking about trying a shorted parallel cable..
02:00 PM syyl_: time to scrap some tools in the process of learning how to sharpen them ;)
02:00 PM fragalot: syyl_: looking good :D
02:01 PM gloops: very nice syyl
02:01 PM infornography: thats clean
02:01 PM gloops: some purists would argue that you should never have tried to remove the priceless patina
02:02 PM fragalot: syyl_: does it have any wear in it at all?
02:02 PM gloops: but it looks very nice
02:02 PM syyl_: no, its unused since built in 1999 :D
02:02 PM fragalot: gloops: it doesn't look like he removed any patina
02:02 PM syyl_: but it was basicaly a kit to be finished by the owner ;)
02:02 PM syyl_: chineseium
02:02 PM fragalot: I see
02:03 PM fragalot: nothing wrong with chinesium kits :-)
02:03 PM syyl_: for example the bellows on the vertical axis. there where none - all the grit from grinding would wear the column right away
02:03 PM gloops: right - i guess i was just flagging up the need to preserve patina on old machines, where it applies
02:03 PM syyl_: :)
02:04 PM fragalot: I need to replace the wipers on my mill
02:04 PM fragalot: currently they appear to be soft neoprene, about 15mm thick
02:05 PM fragalot: well, it USED to be soft, now half of it is glass hard
02:05 PM gloops: soft is better than brittle..no?
02:05 PM syyl_: and thats what cooleant does with rubbery materials :D
02:05 PM fragalot: does regular felt work, or does this have to be something more fancy
02:05 PM syyl_: natural felt
02:05 PM syyl_: be sure to get proper natural one, not the arts-craft-store stuff, that can have abrasive shit in it
02:05 PM * fragalot => ebay
02:07 PM fragalot: syyl_: semi compressed, or 'standard' ?
02:08 PM syyl_: uhm
02:08 PM syyl_: wow :D
02:08 PM syyl_: that stuff i got from a local felt place is very firm
02:08 PM fragalot: compressed it is
02:09 PM fragalot: hm, seems all the ebay felt is either super loose or has adhesive pre-applied >.>
02:09 PM syyl_: hmm
02:10 PM syyl_: i think you could use a hard felt polishing pad
02:10 PM syyl_: if they are large enough
02:10 PM fragalot: the wiper on the Z axis is about 220mm wide
02:10 PM syyl_: ops
02:10 PM fragalot: :D
02:27 PM gloops: Italexit looking increasingly likely
02:29 PM gloops: i wonder what ramifications this will have for DIY CNC builders the world over, given Italys enormous contribution to to the sector
02:29 PM fragalot: that's just a shite name
02:30 PM Chillum: lazy
02:30 PM Chillum: at least it is not ItalexitGate
02:30 PM fragalot: lol
02:30 PM gloops: italy-exit
02:30 PM gloops: how else can you really combine the words?
02:30 PM fragalot: gloops: Italeave.
02:31 PM gloops: hmm not bad
02:31 PM gloops: Italout
02:31 PM fragalot: don't push it
02:32 PM gloops: theyre known for flipping at the last minute anyway, so nothing is given
02:33 PM Chillum: Italegress
02:33 PM fragalot: brilliant.
02:33 PM Chillum: Italpartire
02:34 PM gloops: ItIndi
02:34 PM fragalot: Italnie?
02:34 PM gloops: that would be Italniente
02:38 PM XXCoder: italy is exiting EU?
02:42 PM gloops: when volvos were almost sexy https://scontent.fman1-2.fna.fbcdn.net/v/t1.0-9/40551589_1921278224582425_1209193431679631360_n.jpg?_nc_cat=0&_nc_eui2=AeHVNPkkXc6rAoicbxRUvpkOzybOAM5Q6_Nt9nddgouzz2_h7lf6F4vEXiErTmXxhPgFB52HOStYGz_twhehL3wYm3u6Tsl6sW1U7Twauvwymg&oh=eba23d1ad6a82ce0d0a1e1096fe67ef4&oe=5BF41930
02:43 PM gloops: XXCoder the chances of Italy leaving the EU have shortened considerably yes
02:44 PM XXCoder: so much lower chance of leaving eh
02:45 PM gloops: no, much lower chance of remaining
02:46 PM pink_vampire: what could possibly go wrong - offsets, clamping, fixturing https://www.youtube.com/watch?v=jHbI_B2sPA0
02:46 PM XXCoder: ah. your statement have ambiguity in it thats why its confusing.
02:47 PM XXCoder: first one: failure to dry run first
02:48 PM pink_vampire: XXCoder: offset the z wrong
02:48 PM XXCoder: yeah dry run would expose that without breaking anything
02:48 PM XXCoder: third is programming error, not set safety z height high enough
02:49 PM pink_vampire: i think i was -+ issue
02:50 PM XXCoder: so many of em doesnt even walk in! jeez!
02:50 PM XXCoder: unproven program, unproven setup, always walk in in very least
02:52 PM XXCoder: the one with nut is why I like Z rise first then XY movement
02:52 PM XXCoder: last one yeah fixture setup problem lol
02:53 PM pink_vampire: i like the simulation in HSM
02:53 PM XXCoder: isnt it also show tool and head so it would show if any issues?
02:55 PM pink_vampire: it can do full machine simulation
02:55 PM XXCoder: nice! though even if you checked it over in sim, always walk first part after setup, because everyone makes mistakes.
02:56 PM XXCoder: https://www.youtube.com/watch?v=lw4ZDCBjAhg second one EWWW hand is NEVER a good clamp!
02:56 PM XXCoder: (no hurt besides burn from sheer stupidity)
02:56 PM syyl_: haha pink_vampire, 1:15 is always great
02:56 PM syyl_: that machine will not be happy after the crash
02:57 PM XXCoder: one where head lifted and turned a little?
02:57 PM gloops: https://www.facebook.com/woodworkingextreme/videos/2211248742477141/
02:57 PM pink_vampire: syyl_: I'm wondering hat will happen with 60K rpm
02:57 PM gloops: who hasnt done that
02:57 PM syyl_: i crashed a bunch of tools in the datron at work
02:57 PM syyl_: with a 40k spindle
02:58 PM XXCoder: I crashed only once
02:58 PM pink_vampire: gloops: this is why we have cnc
02:58 PM syyl_: but nothing that massive
02:58 PM XXCoder: I destroyed $1,00 chuck collet cat50
02:58 PM fragalot: I've crashed a machine running batch parts all day
02:58 PM fragalot: suddenly the toolchanger decided that the 50mm drill wasn't what it wanted
02:58 PM fragalot: so it tried to drill with the haimer
02:58 PM pink_vampire: I hope not crushing any thing
02:59 PM syyl_: most of the time the axis go into over-current bevor anything major looses its shit
02:59 PM syyl_: ouch, fragalot
02:59 PM fragalot: also had a barfeeder go wrong overnight
02:59 PM XXCoder: fragalot: dang
03:00 PM fragalot: fun times :-)
03:00 PM syyl_: i will never forget how the dmg 50v decided to drop the renishaw in front of the toolchanger :D
03:00 PM pink_vampire: the only fail as set Z10 instead of offset it to 0, aand it mark the vise jaw
03:00 PM syyl_: *plock*
03:00 PM fragalot: syyl_: xD
03:00 PM XXCoder: fragalot: thats expensive lol
03:00 PM fragalot: XXCoder: yes it was, barfeeder was scrapped
03:00 PM fragalot: and the lathe needed new bearings
03:01 PM * fragalot is looking at toe jacks
03:01 PM fragalot: any recommendations?
03:01 PM syyl_: or the shitty eberle cnc router that decided to break its own toolchanger
03:01 PM syyl_: http://gtwr.de/div/eberle001.jpg
03:01 PM syyl_: http://gtwr.de/div/eberle002.jpg
03:02 PM syyl_: needed a bit of rebuilding ;)
03:02 PM fragalot: haha
03:02 PM pink_vampire: syyl_: BUT WHO??
03:02 PM syyl_: that was a controller-glitch
03:02 PM pink_vampire: it was linux cnc?
03:02 PM syyl_: nope
03:02 PM pink_vampire: than fine.
03:03 PM syyl_: a windows based retrofit
03:03 PM syyl_: by a company called "knotenpunkt"
03:03 PM fragalot: ha. windows
03:03 PM pink_vampire: I'm lazy
03:03 PM fragalot: windows is probably one of the worst choices for realtime
03:03 PM pink_vampire: I need help
03:03 PM syyl_: http://gtwr.de/div/eberle005.jpg
03:04 PM fragalot: syyl_: I like the percussive maintenance claw hammer in the back
03:04 PM syyl_: after straightending the pneumatic cylinder and reballing the linear guide it kinda worked until i got spare parts :D
03:04 PM syyl_: oh thats a non-marring hammer
03:05 PM fragalot: it's got the exact same handle as my (ancient) claw hammers
03:05 PM XXCoder: syyl_: ow
03:05 PM syyl_: :D
03:05 PM syyl_: the machine itself was very nice
03:05 PM syyl_: http://gtwr.de/div/qtl2_2.jpg
03:06 PM XXCoder: pink_vampire: you actually do stuff, which is way more thjn I do lol
03:06 PM syyl_: all cast iron construction, 400W yaskawa servos, ibag spindle
03:07 PM pink_vampire: what is the max size tool diameter you can use in the ibag?
03:07 PM syyl_: largest was a 10mm collet
03:07 PM syyl_: took #20 taper tooling
03:07 PM pink_vampire: I'm limited to 1/4" :(
03:07 PM syyl_: with 6mm tooling the machine could fly
03:07 PM pink_vampire: the the torque on the HF is not grate..
03:07 PM syyl_: 10mm was a bit much for it
03:08 PM syyl_: but hardmilling steel, with a 6mm endmill worked brilliant
03:08 PM pink_vampire: also here. hard mill is nice. but I love PVC
03:09 PM pink_vampire: the fact that yu can glue is and use it so fast
03:09 PM pink_vampire: you*
03:10 PM pink_vampire: are you using any tools like face mill / fly cutters?
03:10 PM syyl_: not in the router
03:11 PM syyl_: i own and use a facemill for my manual mill
03:11 PM fragalot: fly cutter going 40k rpm would be interesting
03:11 PM syyl_: there are small facemills for that purpose
03:11 PM pink_vampire: fragalot: LOLL
03:11 PM fragalot: i've got a facemill, but still use a flycutter sometimes just for cosmetic purposes
03:11 PM fragalot: the facemill is GREAT though
03:11 PM fragalot: it's super economical in terms of inserts
03:12 PM syyl_: i used a small round-insert cutter in the datron
03:12 PM fragalot: as it only ever wears out 1 at a time
03:12 PM XXCoder: yeah theres quite small facemills
03:12 PM syyl_: 16mm diameter
03:12 PM XXCoder: its great for certain uses
03:12 PM syyl_: worked brilliant for steel
03:12 PM XXCoder: sjmallest I have used is one inch but im sure there is smaller
03:12 PM syyl_: they go down to 8..10mm
03:12 PM syyl_: havent seen them smaller
03:14 PM pink_vampire: you can use stuff larger then the collet size, and you can go to a torque issue
03:14 PM pink_vampire: but unbalanced cutter on HF spindle = russian roulette
03:14 PM fragalot: y'know what. I was planning to get my own toe jack & machine rollers to shift things around
03:14 PM syyl_: and, already ordered?
03:14 PM fragalot: but now that i've actually found a place to get them from, and the pricing... I think I'll just continue borrowing them :D
03:15 PM syyl_: haha :D
03:16 PM pink_vampire: toe jack on wooden floor would be interesting
03:16 PM fragalot: no it wouldn't
03:16 PM pink_vampire: it will crack the floor
03:17 PM fragalot: which isn't interesting, just poor planning :D
03:17 PM Wolf__: breaking floor joists is always great
03:22 PM Wolf__: johnson bar might be better for small shop vs toe jack
03:22 PM fragalot: yes and no
03:22 PM fragalot: problem with those is that they don't reach high enough to get it off of the blocking it's on now
03:22 PM Wolf__: if you have room lol
03:23 PM fragalot: that too
03:23 PM fragalot: I've decided that it's kinda like a van
03:23 PM fragalot: it's better to have a nice friend that lets you borrow his than it is to have your own :D
03:23 PM Wolf__: lol
03:25 PM Wolf__: could stack up wood to get the height needed to lift it and work the machine down little at a time
03:25 PM fragalot: true, I could do that with the big crowbar too probably
03:27 PM fragalot: not much to grab on to casting wise on the schaublin though
03:27 PM Tom_L: fragalot why you raisin rodents in your coolant anyway?
03:27 PM fragalot: Tom_L: was as-delivered :P
03:27 PM Tom_L: ahh
03:27 PM fragalot: I thought they were globs of grease at first
03:27 PM Tom_L: wonderful
03:28 PM fragalot: until I noticed little tails
03:28 PM fragalot: and legs
03:28 PM Tom_L: heh
03:28 PM fragalot: and then a bigger tail
03:28 PM fragalot: smelled awful.
03:30 PM fragalot: the return line wasn't hooked up, so i'm guessing they crawled in and couldn't get out again
03:32 PM Wolf__: heavy mouse trap
03:36 PM CaptHindsight: fragalot: way back in the Win 3.1 and 95 days there was a real time kernel that worked pretty well
03:36 PM fragalot: CaptHindsight: back then, sure.
03:36 PM CaptHindsight: pre horrible cruft years
03:38 PM MrHindsight: about 10 years ago I ran into a demo at IMTS from a Uni that used Winders and some real time "kernel"
03:39 PM MrHindsight: they said they had <1uS latency response using a PC
03:39 PM fragalot: that's not bad
03:39 PM fragalot: did they mention the 100ms jitter?
03:40 PM MrHindsight: i forgot who came across some motherboard that had that sort of jitter with RTAI
03:40 PM MrHindsight: nah, they were doing micro machining (~1um features)
03:41 PM MrHindsight: they were however completely unaware of LCNC and RTAI
03:41 PM fragalot: a lot of people are
03:42 PM MrHindsight: University micro machining lab
03:42 PM Tom_L: did you see the military printing concrete with it though?
03:42 PM MrHindsight: i gave him my contact info and linuxcnc.org, never heard back
03:43 PM Tom_L: https://3dprintingindustry.com/news/u-s-marines-use-3d-printing-to-rapidly-construct-concrete-barrack-139125/
03:43 PM MrHindsight: every time I get contacted by the guberment labs they are using Winders
03:43 PM MrHindsight: yes, just like the Chinese :)
03:44 PM MrHindsight: gee, go print some hospitals for mental health treatment
03:45 PM Tom_L: see the monitor in the 2nd pic?
03:45 PM Tom_L: the guy on the left should be written up by OSHA though
03:46 PM MrHindsight: looks like Axis
03:46 PM Tom_L: :D
03:46 PM MrHindsight: he has a steel plate in his head, internal helmet
03:46 PM Tom_L: kinda looks that way ehh?
03:48 PM Wolf__: wow, they totally cloned a crappy desktop 3d printer, all the way to belt drive axis
03:53 PM XXCoder: whats you suggest? 10 feet long ballscrews?
03:53 PM Wolf__: no way, 30 foot ball screw
03:54 PM XXCoder: lol
03:54 PM XXCoder: imange the roller or lathe that large
03:54 PM Wolf__: really gear rack drive
03:54 PM XXCoder: honestly for knock down and cargo ops I would use belts, or double belt rack drive system
03:55 PM XXCoder: that setup kinda suycks, I can see slight overextrusion and ringing
03:55 PM XXCoder: but same time who cares its temp structure
03:56 PM Wolf__: yeah, application matters, smoother then sandbags and canvas
03:57 PM XXCoder: ya know if it redesigned to makje double walled, inside walls can be filled with sand
03:57 PM XXCoder: amazing isulation and damn near bulletproof
03:57 PM fragalot: that's a common method, XXCoder
03:57 PM fragalot: with the 3D printed concrete strucutures, often a shell is printed that is filled at a later point
03:57 PM XXCoder: cool
03:57 PM fragalot: for buildings, typically insulation is added
03:58 PM XXCoder: i wonder how isulating sand is
03:58 PM fragalot: and in other cases, the insulation can also be the mold for the concrete pour later.. but that's not 3D printing so not relevant :P
03:59 PM Wolf__: IFC blocks are pretty cool as well
04:00 PM XXCoder: looked that up. pretty cool
04:01 PM XXCoder: Wolf__: is it short term or perment?
04:01 PM XXCoder: looks perment
04:01 PM Wolf__: permeant, usually put siding over the outside and drywall inside
04:02 PM XXCoder: im interested on rammed earth structures though
04:04 PM XXCoder: rammed earth isnt too good in wa though, need protection from rains
04:05 PM pink_vampire: https://www.youtube.com/watch?v=u6-2Bf_5ojY skip to 1:22 and I have a cnc mill!
04:10 PM CaptHindsight: built at the U.S. Army Engineer Research and Development Center in Champaign, Illinois
04:10 PM _unreal_: YAY MY CNC RPI HAT arrived...
04:10 PM _unreal_: SHIT I have to solder the pins on
04:11 PM CaptHindsight: https://www.3ders.org/articles/20171220-scg-3d-prints-3m-tall-triple-s-concrete-building-with-new-surface-structure-shelter-concept.html
04:11 PM CaptHindsight: barracks with style
04:12 PM Deejay: gn8

04:13 PM XXCoder: CaptHindsight: damn that is cool
04:15 PM XXCoder: heh first concept usage usually is by rich, but i predict it will evenually be used for cheap housing only
04:15 PM CaptHindsight: http://www.3ders.org/articles/20180830-us-marines-3d-print-500-square-foot-concrete-barrack-in-just-40-hours.html

04:17 PM CaptHindsight: one gantry directs the nozzle, the other holds the hose
04:18 PM CaptHindsight: The team designed a 3D model on a 10-year-old computer.
04:19 PM CaptHindsight: sounds like LCNC
04:28 PM _unreal_: There not including soldering 90% of my RPI cnc hat for my asus tinker board has been put together
04:35 PM gregcnc: Capthindsight https://media.defense.gov/2018/Aug/23/2001958128/-1/-1/0/180822-M-ZZ999-003.JPG
04:39 PM XXCoder: still easier than regular I guess lol
04:40 PM pink_vampire: gregcnc: I know this plot view...
04:45 PM _unreal_: arg
04:52 PM gregcnc: pink_vampire built anything interesting?
04:52 PM gregcnc: oh did you get the lathe back together?
04:53 PM pink_vampire: I'm working on the most silly thing that was supposed to be done ages ago
04:53 PM pink_vampire: the VFD mount
04:54 PM gregcnc: For the lathe? you didn't keep the original motor?
04:54 PM pink_vampire: yeah the lathe is up and running like a charm
04:55 PM pink_vampire: I even got a new gear fork for it
04:55 PM gregcnc: iirc you cab still get parts for those
04:57 PM pink_vampire: it is not "new" it is "used but like new"
05:00 PM _unreal_: OMG I have one of these https://thepihut.com/products/aluminum-heatsink-cooling-fan-for-lattepanda
05:00 PM _unreal_: I'm thinking of useing the one I have to cool my asus tinker board
05:01 PM _unreal_: the heatsink that comes with it is a little to tall
05:01 PM pink_vampire: I have RPI 3 here
05:01 PM _unreal_: not even really to tall I can manage but the rpi cnc hat touches the heat sink
05:01 PM _unreal_: that comes with the tinker board
05:02 PM _unreal_: dont know if it would be a good choice or not
05:02 PM _unreal_: all I do know is that I dont like that it makes a major HEAT trap with that hat on
05:03 PM _unreal_: I'm thinking active cooling or different heat sink or combinations
05:03 PM _unreal_: I have a second heat sink that is low enough BUT it has fewer fins. yet its a slightly larger foot print
06:34 PM _unreal_: OMG I like these https://modmymods.com/radiators/40mm-radiators.html
06:38 PM Wolf__: 40mm? weak
06:40 PM _unreal_: Wolf__, not looking at a lot of heat
06:40 PM Wolf__: 40mm fan = noise
06:46 PM Roguish: Wolf__: get a peltier cooler https://www.amazon.com/DAOKI-TEC1-12706-Heatsink-Thermoelectric-Cooling/dp/B00XT0OZY0?SubscriptionId=AKIAILSHYYTFIVPWUY6Q&tag=duckduckgo-ffab-20&linkCode=xm2&camp=2025&creative=165953&creativeASIN=B00XT0OZY0
06:46 PM Roguish: silent
06:47 PM Wolf__: why tag me on that...
06:47 PM Roguish: sorry, _unreal_ ..............................
06:48 PM Wolf__: :)
06:48 PM Wolf__: I was looking at 120mm x240mm radiators
06:49 PM Wolf__: but thats for co2 laser cooler
06:56 PM _unreal_: huh?
07:36 PM _unreal_: Roguish, I'm not using a piltier
07:37 PM Roguish: theyre cooool
07:37 PM _unreal_: no argument
08:15 PM pink_vampire: what are going to cool down??
08:17 PM XXCoder: water
08:18 PM XXCoder: co2 laser needs a lot of cooling
08:22 PM pink_vampire: piltier for laser???
08:22 PM XXCoder: noit going to happen lol
08:22 PM pink_vampire: it is a diode?
08:24 PM XXCoder: nah co2 like i said. Roguish linked that to wolf by mistake its unreal that needed smaller scale cooling
08:35 PM Wolf__: I was planning a water chiller made from a old dehumidifier for a 120W co2 laser
08:36 PM pink_vampire: like the dehumidifier for 50$ from walmart???
08:36 PM Wolf__: no, like $5 yard sale
08:37 PM pink_vampire: I never thought that you can cool something with it.
08:37 PM Wolf__: its a freon compressor inside
08:39 PM pink_vampire: i need to lower the temp of the spindle coolant
08:39 PM XXCoder: yeah it works by cooling air so water gets out
08:39 PM XXCoder: so not surpised
08:39 PM XXCoder: theres other way, compressor type
08:40 PM XXCoder: he dont need that though as it dont actually cool air
08:40 PM Wolf__: well, inside the dehumidifier is the same innards as a window ac unit
08:42 PM Wolf__: only difference is its all in one line in the air path, high and low side coils
08:52 PM pink_vampire: small office fridge
08:52 PM Wolf__: same innards as well
08:52 PM _unreal_: I'm looking at options for cooling my tinker board
08:53 PM pink_vampire: but it is much easyer to put a bucket inside
08:53 PM Wolf__: dehumidifier is quicker to use to add a 240mm x 120mm radiator in to the mix behind the condenser coil
08:54 PM Wolf__: one thing about machine cooling is you need to keep the coolant above dew point of the room
08:54 PM pink_vampire: where do you get 240mm x 120mm radiator??
08:54 PM Wolf__: amazon/ebay
08:54 PM XXCoder: car juniyard
08:54 PM _unreal_: heh I got a few different one's long time ago
08:54 PM pink_vampire: https://www.aliexpress.com/item/240mm-dual-2-X-120mm-Radiator-Copper-Water-Cooling-Radiator-Heat-Exchanger-single-pass/32708709630.html
08:54 PM pink_vampire: 28$
08:57 PM Wolf__: forgot shipping there
08:57 PM XXCoder: car junkyard.
08:57 PM XXCoder: people RARELY grab radiators. just find car that still has coolant and grab it
08:57 PM Tom_L: the ultimate in high tech cooling: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/spindle_cooler/Cooler5.jpg
08:57 PM pink_vampire: but it is 28$ + dehumidifier
08:58 PM XXCoder: Tom_L: very high end indeed.
08:58 PM Wolf__: http://a.co/d/97ZWo9E comes in quicker
08:58 PM Tom_L: it works better than i expected actually
08:58 PM pink_vampire: Tom_L: for DC??????
08:58 PM Tom_L: it's a dc motot yes
08:58 PM Tom_L: motor
08:58 PM pink_vampire: vent the motor and add a fan
08:58 PM XXCoder: Tom_L: you probably just need a very small mod to make it dump into radator which then dumps to tank below
08:59 PM pink_vampire: you just cool down the case
08:59 PM XXCoder: then suck from that up which has a lot more cooling power
08:59 PM Tom_L: this was available and cost me $0.00
08:59 PM pink_vampire: Tom_L: to vent it it's also 0.00$ you have a cnc...
08:59 PM Tom_L: i fill the bucket with ice too...
08:59 PM Tom_L: pink_vampire yeah but that'll let all sorts of crap in
09:00 PM XXCoder: ah isnt that take a bit more work than simply using radator though?
09:00 PM pink_vampire: on the back plate???
09:01 PM Wolf__: cooling the motor case is better then nothing, long as its a inductive motor
09:01 PM pink_vampire: Wolf__: it is dc, the case just hold the magnets
09:02 PM Wolf__: chat window was hiding the brush holder
09:06 PM Wolf__: but yes, thats why I said inductive motor...

09:09 PM XXCoder: pretty cheap
09:09 PM Wolf__: nice
09:10 PM Wolf__: bigger for a few buck more http://a.co/d/64pPmxz

09:13 PM Tom_L: smaller for a few bux less
09:14 PM pink_vampire: Tom_L: did you put any paste?
09:14 PM Tom_L: no
09:14 PM Tom_L: i could but it works ok as it is
09:15 PM pink_vampire: how it is cool the coils?
09:15 PM Tom_L: and it would just make a big mess
09:15 PM Tom_L: i use ice in the bucket so nice and cool
09:15 PM Tom_L: and the motor lid is warm to the touch
09:15 PM Tom_L: after a pretty good workout
09:16 PM pink_vampire: hope for you the motor will last
09:16 PM Tom_L: i'm sure i could make it more efficient but it does the job
09:17 PM Tom_L: i don't push it to the limit
09:18 PM Tom_L: i did a ~4-6hr part a while back and it did fine
09:19 PM pink_vampire: that nice
09:20 PM Tom_L: i've got a spare motor just in case but i think it will do ok
09:29 PM infornography: if a chopper drive uses PWM to drive a stepper at a higher voltage, if you drive a stepper rated for the higher voltage the duty cycle should go to 100% right? *thonk*
09:32 PM infornography: it should act like a switch at that point by my logic, but I don't have a spare driver to burn up yet

09:38 PM Tom_L: https://learn.adafruit.com/all-about-stepper-motors/matching-the-driver-to-the-stepper
09:38 PM Tom_L: that should keep you busy a while
09:38 PM infornography: if the motors rated amps is at the supply voltage of the driver, there would be nothing to chop
09:39 PM infornography: it will
09:39 PM Tom_L: but you have more to gain if you use a higher voltage
09:40 PM infornography: but I already have some 24v motors, I want to put them to use
09:41 PM infornography: I might try to make a simple on/off driver at some point
11:42 PM gloops: early to bed, early to rise
11:51 PM ziper: gloops, https://www.youtube.com/watch?v=4zw1Bli1jbc
11:57 PM gloops: well, cant make noise this time of morning, only thing to do is practice cam/drawing stuff
