02:43 AM Deejay: moin
05:00 AM jthornton: morning
05:01 AM XXCoder: hey
05:14 AM jthornton: https://www.youtube.com/watch?v=yva_FaMxdiE
05:15 AM jthornton: does this go too fast?
05:15 AM XXCoder: looking
05:15 AM Tom_L: morning
05:15 AM jthornton: yo
05:16 AM Tom_L: looks ok. if they need a detail they can stop and rewind
05:16 AM Tom_L: if they're new to it, they will anyway
05:16 AM jthornton: thanks
05:17 AM Tom_L: no sound here though
05:17 AM XXCoder: speed seems ok yeah. unless youre speaking faster than president keendy
05:17 AM jthornton: all the videos I watched try to cover way too much crap
05:17 AM jthornton: yea, dunno where the microphone is lol
05:18 AM Tom_L: no, this pc has no sound :)
05:18 AM jthornton: oh there is no audio track
05:19 AM pink_vampire: hi
05:19 AM jthornton: yo
05:19 AM XXCoder: hey pink
05:19 AM XXCoder: jt well its very clean and to point
05:19 AM XXCoder: freecad desperately needs docs and good tutorials.
05:19 AM jthornton: 1 down lol
05:20 AM sensille: Loetmichel: do you have an idea what aluminum alloy our 6040 is made of?
05:21 AM XXCoder: unobtainium
05:21 AM jthornton: lol
05:22 AM sensille: chinesium, yes
05:22 AM XXCoder: :)
05:22 AM jthornton: never heard of 6040 alloy
05:23 AM sensille: 6040 is the name of the machine
05:23 AM jthornton: ah
05:23 AM sensille: was thinking if it might make sense to replace the alu parts by 7075 alu
05:23 AM jthornton: does it flex now?
05:24 AM sensille: to make it stiff enough to mill steel. and then replace the parts by steel. bootstrapping :)
05:24 AM pink_vampire: sensille: just made out of steel
05:24 AM sensille: it does
05:24 AM sensille: it flexes too much to mill steel
05:25 AM jthornton: https://www.youtube.com/watch?v=zdllMYgsAkg
05:25 AM XXCoder: even with light touch?
05:25 AM pink_vampire: use smaller and sharper cutters
05:25 AM sensille: Loetmichel tried it and failed. haven't tried myself
05:25 AM jthornton: is that the machine you have?
05:26 AM sensille: no
05:27 AM jthornton: which one do you have?
05:27 AM sensille: https://www.ebay.de/itm//272728775761
05:28 AM jthornton: pretty similar to the video
05:28 AM sensille: the one in the video might be out of steel
05:28 AM jthornton: put a plate of MIC6 on it
05:28 AM sensille: well, not the bed :)
05:28 AM jthornton: he added the steel plate
05:28 AM sensille: the bed is not the problem, the gantry is
05:28 AM jthornton: hence the title of the video improve the 6040
05:29 AM jthornton: the gantry sides flex left/right?
05:29 AM Tom_L: if you're gonna mill steel, you need mass too
05:29 AM jthornton: aye
05:29 AM XXCoder: sensille: you could add some more structure too
05:29 AM Tom_L: swapping alloys won't do alot of good
05:30 AM sensille: XXCoder: to the sides?
05:30 AM sensille: mass to reduce vibrations?
05:30 AM jthornton: which way does it flex?
05:31 AM sensille: sideways, yes
05:31 AM XXCoder: yeah though does it flex so gantry sides is curved or is it bent offset from base of gantry?
05:31 AM XXCoder: or well both
05:31 AM sensille: have to look closer, dunno
05:32 AM sensille: will spend an hour in the evening with my dial gauge
05:32 AM XXCoder: honestly its not made to mill harder metals
05:33 AM sensille: i know. so you don't think replacing the structure by steel would be enough?
05:35 AM XXCoder: not quite
05:35 AM XXCoder: gantry is weak area
05:35 AM jthornton: the Y axis bearings are probably a weak link
05:35 AM XXCoder: yeah that too
05:35 AM XXCoder: jt isnt there umm other kind of bearings? thrust something?
05:35 AM XXCoder: much stronger
05:36 AM jthornton: well linear rail bearings would be good
05:36 AM sensille: it would be enough if i could mill it with a very small stepdown, like 0.1mm
05:37 AM jthornton: yea shallow depth of cut and for aluminum some dish soap as lube
05:37 AM sensille: or even 0.05mm. for alu i use 0.2mm
05:37 AM XXCoder: heh other place I used to work at used wd-40
05:37 AM XXCoder: cnc router, huge one
05:37 AM jthornton: lol water displacer 40
05:39 AM XXCoder: yah. its surpising effective
05:40 AM jthornton: on aluminum?
05:40 AM XXCoder: yeah normally just spray over sheet and let it run
05:40 AM sensille: i'm milling alu dry, works for 5083 and 7075
05:40 AM sensille: not for 6060
05:40 AM XXCoder: there was one part where 1/8 is used since theres really tiny gap between 2 areas of a part
05:41 AM XXCoder: had to constantly spray wd40 at that spot lol
05:41 AM XXCoder: crazy big cnc router dont have coolant anythong
05:41 AM XXCoder: big enough for you to park car on
05:41 AM jthornton: wow
06:54 AM jthornton: 46°F and rain
06:54 AM XXCoder: 32f right now heh
06:54 AM XXCoder: humidity at shop was 18%
06:54 AM XXCoder: dry eyeball time
06:58 AM Tom_L: 35F, Hi 35, Lo 22
07:00 AM XXCoder: wed should be 46-36f
07:00 AM XXCoder: warmer than now
08:13 AM Edoctoor is now known as bozo
08:41 AM bozo is now known as Edoctoor
10:04 AM net|: http://www.netpipe.ca/apps/wiggley/widgets_wiggly.html
10:05 AM pink_vampire: O_O?
10:07 AM pink_vampire: net|: ?
10:08 AM pink_vampire is now known as pi9nkOK
10:11 AM pi9nkOK is now known as pink_vampire
10:12 AM * t4nk_freenode creeps up behind pink_vampire with a little mirror
10:12 AM t4nk_freenode: FAKE!!!!!
10:13 AM pink_vampire: hi
10:13 AM t4nk_freenode: 'lo there
10:13 AM pink_vampire: I'm pink_vampire
12:23 PM Loetmichel: sensille: some "knetlegierung" because its extrusion all the way
12:24 PM Loetmichel: but replacing it with 7075 will not help
12:24 PM Loetmichel: the alu parts are good enough. the fact that the gantry has unsupported rails is the culprit
12:25 PM Loetmichel: design a new gantry thats a lot stiffer and has supported rails and that thing can mill steel.
12:25 PM sensille: you mean the rods?
12:28 PM Rab: sensille, yeah, those are termed "rails". If they're only supported at the ends, they can flex. Supported rails are more rigid: https://www.pbclinear.com/PbcLinear/media/Products/Round%20Shaft%20Tech/Support%20Rails/SRACC_Main.jpg
12:29 PM sensille: Loetmichel: so you think the ballscrews are good enough?
12:33 PM Loetmichel: yes
12:34 PM Loetmichel: re from work bttw. Finally got the CNC604 housings nearly done (one at least, and the front window is still missing) -> http://www.cyrom.org/palbum/main.php?g2_itemId=17574
12:35 PM sensille: i want more Z anyway, so a new gantry would be nice
12:37 PM Loetmichel: ... and then i tried to mill the mounting holes for the sacrificial plate... -> http://www.cyrom.org/palbum/main.php?g2_itemId=17577 <- WTF isnt that round???
12:37 PM sensille: and an enclosure would be nice, too, looks good :)
12:37 PM Rab: Loetmichel, eww: http://www.cyrom.org/palbum/main.php?g2_itemId=11181
12:40 PM Loetmichel: reason: http://www.cyrom.org/palbum/main.php?g2_itemId=17580 <- thats the coupling y stepper to ballscrew. NIce china quality. not even 1 hour on the machine... :-(
12:45 PM Tom_L: those couplers are no good
12:45 PM Loetmichel: indeed
12:46 PM Tom_L: it's like tying the motor and shaft together with a spring
12:48 PM Loetmichel: Tom_L: if it only were a spring
12:49 PM Loetmichel: as in spring steel, meant to bend. not aluminium that will break after a few 100 light bends
12:50 PM Loetmichel: i surmise that one of the coupler sides has an off-angle bore
12:50 PM Loetmichel: you could hear the machine change the moving sound with each rotation as if it had more/less force to overcome
12:56 PM Loetmichel: Rab: nothing to mention. Just lost a few mm of my left thumb to the bandsaw
12:56 PM Loetmichel: happens
12:56 PM sensille: regrows
12:56 PM Loetmichel: s/few/couple
12:56 PM Loetmichel: sensille: more or less ;)
01:11 PM * JT-Shop needs to find a small audio stereo amplifier
01:37 PM jymmmm: Welcome to BLACKOUT day 4,231,432.3
01:40 PM pink_vampire: here it is design day
01:41 PM pink_vampire: jymmmm: what do you think looks better? https://i.imgur.com/4Efl5bh.png VS https://i.imgur.com/KcoXiKt.png
01:42 PM jymmmm: pink_vampire: Functionality, I'd go for rectangular, then you can easily work on it and modify if needed, even add additional controls/indicators. You have the room for it it seems
01:43 PM pink_vampire: it is solid material
01:43 PM pink_vampire: 3d printed part
01:43 PM jymmmm: does it need to be solid?
01:43 PM pink_vampire: if you want to slam the button
01:44 PM jymmmm: Not necessarily
01:44 PM jymmmm: just thicker walls
01:44 PM jymmmm: or honeycomb
01:44 PM jymmmm: or some other lattice type thing
01:45 PM pink_vampire: I think 50% infill will be fine
01:47 PM pink_vampire: internal stuff https://i.imgur.com/sLsOhXs.png
01:48 PM jymmmm: What if you have to replace the estaop button a couple years down the road, and cant find exact replacement?
01:49 PM jymmmm: You have the room, I'd make a box to make use of that in the future personally
01:49 PM Loetmichel: jymmmm: usually those buttons are pretty standardized
01:50 PM jymmmm: Loetmichel: True, but by the drawing the face looks undersized / "mini" variant
01:50 PM Loetmichel: 22mm hole with a notch for orientation, about the same size of contacts behind that hole.
01:50 PM Loetmichel: they also come with a 16mm hole
01:50 PM Loetmichel: and with 12mm
01:50 PM pink_vampire: it is ABB 22mm standard hole size
01:50 PM Loetmichel: and all of those are pretty interchangeable between manufacturers
01:51 PM jymmmm: IDK, doesn't look very deep to me
01:52 PM pink_vampire: the part is 47mm front to back
01:52 PM jymmmm: YAY the closest (and only) celltower to me is in emergency only mode... AGAIN!
01:52 PM jymmmm: Last time it was 5 days, and that is WITH power restored.
01:53 PM pink_vampire: but you have internet
01:53 PM jymmmm: via wifi, no phone or data service
01:53 PM jymmmm: and only because the generator is running
01:54 PM pink_vampire: go solar
01:55 PM jymmmm: I spent a couple hours this morning installing the valve on the generator oil drain, had to take apart the gen to get it installed... https://i.imgur.com/xBOkbi4.jpg
01:55 PM Loetmichel: jymmmm: you meant to say that your cell tower has a battery backup?
01:55 PM Loetmichel: how luxorious!
01:55 PM jymmmm: pink_vampire: 50 ft trees in the forest and snow
01:56 PM jymmmm: Loetmichel: they all do, or a generator
01:56 PM jymmmm: but 5 days of blackouts dont help
01:56 PM Loetmichel: here in germany i have seen about a dozen of cell towers from the inside.
01:56 PM Loetmichel: NONE of them had backup power
01:56 PM pink_vampire: snow
01:56 PM pink_vampire: here we have only rain
01:57 PM jymmmm: Loetmichel: leave germany? Donate batteries?
01:57 PM jymmmm: Loetmichel: IDK =)
01:57 PM Loetmichel: and if i can belive what a cell tech told me than its about 1 in every 100 towers that actually HAS backup batteries for a few hours of operation
01:58 PM jymmmm: -shrug- I really have no clue, but I'm gonna take a drive and see if I cna find a phone number
01:59 PM jymmmm: But at least now I can do an oil change on the generator at 6am MUCH MUCH easier
02:06 PM Tom_L: jymmmm, that says fuel
02:33 PM * JT-Shop resigns to the fact that he will not get anything done today
02:41 PM jymmmm: Tom_L Yes, yes it does SAY fuel, but it's being used for oil drain valve.
02:42 PM jymmmm: Tom_L IT was $4 with free shipping, worth a shot, and I'm keeping an eye on it
03:50 PM ziper: _unreal_, the machine went for ~1500 bucks
03:52 PM Rab: ziper, which machine?
03:53 PM ziper: cnc router
03:55 PM jymmmm: Tom_L OR... I guess I could just mix gas and oil thru that valve instead, gravity works in reverse during blackouts, right?
03:56 PM jymmmm: Well, heard helicopters, guess they are getting ready to restore power (hopefully)
03:57 PM Tom_L: what's helicopters have to do with the grid?
03:57 PM jymmmm: Tom_L They inspect the tranmission lines before restoring
03:59 PM jymmmm: Tom_L I'm at 2500ft, there's ZERO aircraft flying up here, unless it's an emergency or training, or in this case, inspections.
04:03 PM SpeedEvil: https://www.youtube.com/watch?v=Pla06PO6Odk
04:03 PM SpeedEvil: 4 axis sawblade
04:10 PM Tom_L: just don't cut the lines
04:23 PM SpeedEvil: Indeed.
04:23 PM jymmmm: POWER IS BACK (at least for 30 seconds)
04:23 PM SpeedEvil: yay
04:25 PM jymmmm: Living off grid, whether you want to or not!
04:25 PM SpeedEvil: Technically, still on-grid.
04:26 PM jymmmm: Technically, during a blackout, I am physically discnnected =)
04:26 PM SpeedEvil: Oh - transfer switch?
04:26 PM jymmmm: Yeah
04:30 PM * Tom_L fiddles with jymmmm' grid plug
04:32 PM jymmmm: and THAT's why theres a padlock on it =)
04:46 PM Deejay: gn8
04:47 PM Tom_L: l8r
05:03 PM taloot: helloo guys
05:04 PM taloot: then x86 much faster than this crap arm cpu
05:04 PM taloot: i talk about rpi3 4 and the other boards.
05:05 PM pink_vampire: no idea
05:06 PM pink_vampire: I'm using some old Q cpu for my cnc
05:06 PM pink_vampire: taloot: ^
05:06 PM taloot: https://www.hardkernel.com/shop/odroid-h2/
05:06 PM taloot: i have many retrofit comming
05:07 PM taloot: and im looking for best hardware and software combo
05:07 PM taloot: fast boot machine.. it will be like stand alone controller
05:08 PM taloot: when u press the start button 5 sec and you are in the maachine interfaace
05:08 PM taloot: slow computers slow you down
05:09 PM pink_vampire: I'm using 2 parallel ports, but it is much better to use FPGA card
05:09 PM taloot: yes with new cpu
05:09 PM taloot: those new intel cpu.. lately improved too much
05:09 PM pink_vampire: you don't need much
05:10 PM taloot: 110$ for board + 89$ for
05:10 PM taloot: 210$
05:10 PM pink_vampire: the cpu that I have is Q9300
05:11 PM taloot: what ur latency
05:11 PM pink_vampire: in the latency test?
05:12 PM taloot: yes
05:13 PM pink_vampire: max interval interval 31166
05:13 PM pink_vampire: this is on the base thread
05:14 PM taloot: 95w
05:14 PM taloot: and u are getting 31000
05:14 PM taloot: if u replace it with j1900
05:14 PM taloot: in a year it will pay you back
05:14 PM taloot: on electicty bill
05:15 PM taloot: also u will get less than 5.0 usd
05:15 PM taloot: 5us
05:15 PM taloot: 15w vs 95w
05:15 PM taloot: do the math
05:15 PM pink_vampire: the j1900 is much slower then my cpu
05:16 PM pink_vampire: https://www.cpubenchmark.net/cpu.php?cpu=q9300
05:16 PM taloot: wait
05:16 PM pink_vampire: https://www.cpubenchmark.net/cpu.php?cpu=Intel+Celeron+J1900+%40+1.99GHz&id=2131
05:16 PM taloot: it score in passmark 3154
05:16 PM taloot: i trust passmartk
05:16 PM taloot: the j1900 about 2200
05:16 PM taloot: u can go for j4105
05:17 PM taloot: iit score higher than urs
05:17 PM pink_vampire: I'm not going to touch the computer of the machine
05:17 PM taloot: you become old then :)
05:17 PM taloot: how often ur machines is on
05:17 PM taloot: 24/7
05:18 PM pink_vampire: it was run back then with intel P4
05:19 PM taloot: is there any trick to test if my machine lossing steps or not
05:19 PM taloot: i can install 2 limit switches per joint
05:19 PM taloot: but is there a gcode that can do this test
05:19 PM pink_vampire: just use a dial indicator
05:20 PM taloot: its hard to detect i
05:20 PM taloot: i want mchine to move alot then retun to the specfic locaton
05:20 PM taloot: so if its high or miss the limit switch postion
05:21 PM taloot: if i have high anf low limit sitches
05:21 PM taloot: ithink ican make gcode that oves alot then return to one of th switches
05:21 PM pink_vampire: brb
05:22 PM taloot: i have proximity sensor
05:22 PM taloot: tyt
05:23 PM pink_vampire: you can set a limit switches and also homing switches
05:23 PM pink_vampire: but you can also work fine with just home switches
05:23 PM taloot: but i think there is a way too do it with the gcode.
05:24 PM taloot: yes.. but i want to detect the steps accuracy
05:25 PM Tom_L: G91 G1 X 1 F10
05:26 PM Tom_L: G91 G1 X -1 F10
05:26 PM Tom_L: your indicator should read 0 on return
05:26 PM taloot: dial indicator
05:26 PM taloot: this will move 1 mm
05:27 PM taloot: i want to test in long run
05:27 PM taloot: one mm it can pass. but if i do alot of steps.. lossing step is possabile
05:27 PM taloot: like 3000mm total movement
05:27 PM taloot: or even more
05:28 PM _unreal_: hello
05:28 PM taloot: oif i have 2 limit switches.,.. ..i think there is a way to detect the step.
05:28 PM _unreal_: taloot, hi
05:28 PM taloot: hi unreaal
05:29 PM taloot: how r u today
05:29 PM taloot: i dropped the arm idea
05:29 PM taloot: i will go for intel
05:30 PM taloot: yesterday when you told me that intel much faster even than rpi4
05:30 PM _unreal_: tired
05:30 PM taloot: from kids?
05:30 PM _unreal_: just got home showeed ETC
05:30 PM _unreal_: work
05:31 PM _unreal_: Thats a given
05:31 PM taloot: what type of work u are doing
05:31 PM _unreal_: but thats more to do with software stepping
05:31 PM _unreal_: I work on luxury yachts
05:31 PM taloot: design ?
05:32 PM _unreal_: hands on, tech work, fiberglass, painting you name it
05:32 PM _unreal_: I do a lot of CNC stuff as well
05:32 PM taloot: so u are master in fiber glass
05:32 PM _unreal_: making lables, button panels, cnc'ed parts
05:32 PM _unreal_: yes
05:32 PM _unreal_: hence that thing I showed you the shell you said your interested in
05:32 PM taloot: how about carbon fiber
05:32 PM _unreal_: its all FRP
05:33 PM _unreal_: carbon, kevlar, eglass <--fiberglass
05:33 PM taloot: and your yachts.. how many feet
05:33 PM taloot: you hve
05:33 PM taloot: can i see your site
05:33 PM _unreal_: I have worked on one's that are easily 200'
05:34 PM taloot: you make all parts
05:34 PM taloot: thats hard jop
05:34 PM _unreal_: at times
05:35 PM _unreal_: @#$!@#$ multi keyboards in front of me
05:35 PM taloot: u need a break
05:35 PM _unreal_: taloot, so if your interested in one of the shells what are you thinking? what color what material etc...
05:35 PM _unreal_: I've sold a number of them
05:36 PM taloot: u build it complete
05:36 PM taloot: or just the shell
05:36 PM _unreal_: you can see all the photos
05:36 PM _unreal_: oh
05:36 PM _unreal_: maybe
05:36 PM _unreal_: depends pon the desires
05:36 PM taloot: very good
05:36 PM taloot: how much it cost
05:37 PM taloot: but i will check the screen
05:37 PM taloot: it looks modern. and classic
05:37 PM taloot: uniqe too
05:37 PM _unreal_: :)
05:37 PM _unreal_: ya
05:38 PM _unreal_: I can make it VERY strong or super light
05:38 PM taloot: shell is very impoerant
05:38 PM taloot: specially for cnc
05:38 PM taloot: and the wires
05:38 PM _unreal_: the shells in the photos are strong
05:38 PM taloot: what screens u fit in
05:38 PM _unreal_: something falls on them they are not going to break. something hits the screen thats an other story
05:38 PM _unreal_: the photos show a 7" but a 10" could fit
05:39 PM _unreal_: but you would have 95% display
05:39 PM taloot: i will go for 10
05:39 PM _unreal_: also DEPENDS on your modle
05:39 PM taloot: also i want to place the driver inside the shell
05:39 PM _unreal_: I have one of the RPI 7" touch displays
05:39 PM taloot: and using 5 piin connectors
05:40 PM taloot: small 7"
05:40 PM _unreal_: 5pin?
05:40 PM taloot: yes for the drivers
05:40 PM _unreal_: the lcd I am using has HDMI, VGA, and I think composit in video signals
05:40 PM _unreal_: I'm using HDMI
05:40 PM taloot: https://www.google.com/search?q=aerospace+5+pin&safe=strict&rlz=1C1CHBF_enSA841SA841&sxsrf=ACYBGNTK3P5xa3GuYrvcFjkyDggxznSIaw:1572474859173&source=lnms&tbm=isch&sa=X&ved=0ahUKEwi3upirhcXlAhW2RBUIHUaVDUQQ_AUIEigB&biw=1275&bih=767&dpr=1.5
05:40 PM _unreal_: going from the tinkerboard to the display
05:40 PM taloot: i want x86
05:41 PM taloot: the koeran board
05:41 PM taloot: https://www.hardkernel.com/shop/odroid-h2/
05:41 PM _unreal_: OH
05:41 PM taloot: this
05:41 PM _unreal_: one sec child
05:42 PM _unreal_: ok I think I'm fre
05:43 PM _unreal_: dad, this dad that, dad sign this, DAD
05:43 PM _unreal_: omg.
05:43 PM _unreal_: I used a DB25 connecter on the one I built
05:43 PM _unreal_: well you can see everything thats on it
05:43 PM _unreal_: it can be designed in any way desired
05:44 PM _unreal_: if you look at the first few photos after hatching the parts from the molds
05:44 PM _unreal_: so where holes get cut in etc.... is upto the buyer
05:44 PM _unreal_: I mean hell I could build the thing in SOLID carbon fiber
05:44 PM _unreal_: so you have a carbon fiber surface
05:46 PM _unreal_: ?
05:48 PM _unreal_: taloot, ?
05:54 PM _unreal_: hello
05:55 PM _unreal_: taloot, the only thing with that board is your going to want to do some reasearch on it see if you can find some jitter tests..
05:55 PM _unreal_: That has an onboard GPU that shares the system memory
05:56 PM _unreal_: Same as the tinkerboard
05:56 PM taloot: i can send you model
05:56 PM taloot: include all layout
06:01 PM _unreal_: model?
06:03 PM _unreal_: well First I need to know What is your IDEA. what is it you want finished product. Do you want me to build the entire thing do all of the cutting etc... install hardware ETC...
06:03 PM _unreal_: OR
06:03 PM _unreal_: do you just want the shell with maybe some basic cuts already
06:04 PM _unreal_: next I need to how you want it built.
06:04 PM _unreal_: do you want it with a gelcoat finish an alw grip etc.. if painted WHAT color.
06:04 PM _unreal_: last year I did one for someone who wanted racing tripes.. and the stripes were carbon fiber
06:05 PM _unreal_: do you want something that is all carbon figer?
06:05 PM _unreal_: does it need to be heavy duty
06:05 PM _unreal_: Next does it need to have any mounts built into it
06:06 PM _unreal_: like a backer plate inside so that it can be mounted to a swinging arm or anything like that?
06:06 PM _unreal_: I'm less interested in the hardware and more interested in the building of the main body shell. after we pass that then we can move onto hardware Q&A
06:07 PM _unreal_: What I'm getting at is I dont know how your planning to use the shell
06:07 PM _unreal_: is it going to be a DESKTOP thing? and machine controller
06:08 PM _unreal_: A Job time punch terminal
06:08 PM _unreal_: heh
06:08 PM _unreal_: and=a
06:08 PM _unreal_: taloot, ?
06:13 PM _unreal_: sigh
06:17 PM _unreal_: taloot, hope ya come back soon. because I'm going to the supermarket when my daughter is done with her homework
06:17 PM _unreal_: and I stop getting the DAD i dont get its ;)
06:51 PM taloot: where is there mom
06:52 PM taloot: women onlty take care of there kids
06:52 PM taloot: not throw them and go with another man
06:54 PM taloot: thats why i didnt marry yet
07:01 PM _unreal_: hi
07:01 PM _unreal_: ahh
07:02 PM _unreal_: My Xwife threw her life away and are daughters and are marrage. long story short the courts frowned apone her and smiled on me. I have primary etc... are daughter is 98% always with me
07:02 PM _unreal_: xwife=drugs parts, alcohol etc...
07:02 PM _unreal_: oh well
07:02 PM _unreal_: taloot, soooo
07:04 PM SpeedEvil: She gets to keep the right toes?
07:04 PM _unreal_: huh?
07:04 PM _unreal_: I think you lost me
07:05 PM _unreal_: ?
07:05 PM _unreal_: ok I'll bbiab
07:05 PM _unreal_: going to the supermarket
07:09 PM SpeedEvil: 2%
07:09 PM SpeedEvil: nvm
07:54 PM jymmmm: SpeedEvil: lol, I got it =)
08:08 PM _unreal_: always expensive
08:08 PM _unreal_: $200 smackers later
08:18 PM andypugh: Top Tip! Don’t drink and eBay. I just bid on another boring head. I aleady have two.
08:19 PM andypugh: But the UPA2 is _so_ cute. (not as cute as the UPA1, of course)
08:21 PM andypugh: Actually, Wohlhaupter boring heads are my Pokemon, I really do want to collec them all :-)
08:21 PM Tom_L: you will run out of room
08:22 PM andypugh: OK, not _all_ of them. Just one of each
08:23 PM pink_vampire: hi
08:23 PM _unreal_: low
08:23 PM pink_vampire: https://i.imgur.com/oVGXykk.png
08:24 PM andypugh: That’s subtle.
08:24 PM _unreal_: pink_vampire, is that BIG birthda?
08:24 PM _unreal_: birtha
08:24 PM pink_vampire: it is my mill
08:24 PM andypugh: I am going to go with “pragmatic”
08:25 PM andypugh: You have the same result as my approach to a high-speed mount, but 3 weeks less wrk.
08:25 PM _unreal_: pink_vampire, your going to love my mill that I'm building
08:25 PM pink_vampire: you can see the new pause button with the 3d printed mount for it
08:25 PM _unreal_: the machining company has finally started to cut parts FINALLLY after a fucking year
08:26 PM andypugh: Yes, now you mention it.
08:26 PM _unreal_: pause buttton?
08:26 PM pink_vampire: what machine?
08:26 PM andypugh: I know it’s your machine, and you know what it does. But maybe paint it a different non-e-stop colour?
08:26 PM pink_vampire: that mini E-stop is doing pause / resume
08:27 PM andypugh: Pink, for example.
08:27 PM _unreal_: This is the upper CAD https://drive.google.com/open?id=1M0AEWYBorOkzJdJ7BxX0mm7LE6aypqcy
08:27 PM _unreal_: This is the base https://drive.google.com/open?id=1n8QM01eo2tG-qUacvH3c_0KZn2RtR0VM
08:27 PM _unreal_: hard to tell in the photo but its 30" wide
08:27 PM _unreal_: and 100 lbs
08:27 PM _unreal_: has multi ibeams weled in the middle
08:27 PM pink_vampire: andypugh: according to XXCoder on industrial machines it is also red and also e-stop style button
08:28 PM andypugh: _unreal_: Can I propose a “fin” on the outside of each upright on the gantry for a lot more stiffitude?
08:28 PM _unreal_: andypugh, not aposed, but I am going with 1" thick aluminum
08:28 PM andypugh: Yes, but, well, can you resist the idea of a pink button?
08:29 PM _unreal_: You bastard
08:29 PM * _unreal_ strains
08:29 PM andypugh: I will have you know I was born at least 7 months _after_ the wedding.
08:30 PM _unreal_: ahhh um.... two thumbs way up
08:31 PM andypugh: _unreal_: A couple of elegant flanges would only need three bolts (top, bottom. middle) to make the thing 10x stiffer. Does your CAD package have FEA? You might be surprised
08:32 PM jymmmm: andypugh: but conceived 2 months BEFORE ;)
08:32 PM andypugh: I weighed 4lbs at birth, maybe not.
08:34 PM _unreal_: phat ass
08:34 PM andypugh: (This is way off topic, but I am 50x my birth weight. There are not many people can claim that, and still run up stairs)
08:35 PM Tom_L: heh
08:35 PM _unreal_: I think I'm out of fingers and toes
08:36 PM _unreal_: Ohh. wait I'm a boy I hav e the extra digit... aahh thats the number
08:37 PM andypugh: Are you using binary? That should get you to 2047.
08:38 PM _unreal_: binanalog
08:39 PM andypugh: I wonder if it is reasonable to do trinary on fingers? It’s probably difficult using toes as they tend to be less dextrous.
08:39 PM _unreal_: hehe when I was in my 20's I use to do a stand up comedy routine at a bar. they had this stand up thing on wensdays I use to be a bartender and wait staff... so i was THERE
08:39 PM _unreal_: they loved
08:39 PM _unreal_: me
08:40 PM andypugh: Not sure where this is going. What sort of bar was this where you could demonstrate counting with 21 digits?
08:40 PM _unreal_: jymmmm, sweet your still on line.... I see the squirl power plant is still running strong.
08:41 PM _unreal_: ahhh that was a different joke
08:41 PM jymmmm: _unreal_: Power was restored this afternoon
08:43 PM _unreal_: https://goo.gl/maps/hdY1C4DnvKJqyiQW6
08:43 PM _unreal_: jymmmm, sweet
08:45 PM _unreal_: andypugh, that is the place but there photos suck they dont show the outside
08:45 PM _unreal_: huge outside and outisde bar and stuff

08:47 PM andypugh: Ah, maybe the fuzzy blobs offshore are anchored / bouyed boats?
08:47 PM _unreal_: andypugh, google google maps "bar harbor maine
08:47 PM _unreal_: ok going to have dinner
08:47 PM _unreal_: bbiab
09:02 PM Tom_L: andypugh: <memfrob> Tom_L, speaking of RTAI, I just finished moving the C library out of kernel space
09:02 PM Tom_L: <memfrob> the debs should be based off RTAI 5.2.4 which I'll release soon
09:03 PM andypugh: Is that good?
09:03 PM Tom_L: close to a workin RTAI for linuxcnc?
09:04 PM CaptHindsight: RTAI 5.2.4 is the version that the new LCNC should be based on
09:04 PM andypugh: I thought that the code had to run in kernel space to be relatime in RTAI
09:04 PM Tom_L: they thought you might like to know
09:04 PM andypugh: We do have a working RTAI kernel that works with Buster.
09:04 PM Tom_L: hmm
09:05 PM CaptHindsight: more better working is RTAI 5.2.4
09:05 PM CaptHindsight: or soon to be
09:05 PM CaptHindsight: then he will probably stop RTAI development until his brain stops hurting
09:05 PM andypugh: I am not claiming that it is optimal, and it is 100% based on memfrob’s work. I am just the monkey who has been pulling the LinuxCNC levers.
09:05 PM CaptHindsight: and pick it up again in the future
09:06 PM Tom_L: andypugh right, that's why i'm letting you know of it
09:06 PM CaptHindsight: yeah, he said to wait for 5.2.4 vs what you are using already
09:07 PM andypugh: But I am unclear why it’s a good idea to move things out of kernel space, as I would have thought that might mean that they could be interrupted by other userspace processes.
09:07 PM Tom_L: it would be trick to have a dual boot deb for 2.8
09:07 PM CaptHindsight: I think he said he has that working as of an hour or tow ago but hasn't posted it yet on his github
09:07 PM CaptHindsight: tow/two
09:07 PM Tom_L: i dunno, memfrob is the guru
09:08 PM andypugh: Well, yes, I am merely stating the known boundaries of my ignorance.
09:08 PM CaptHindsight: oh man the Debian configurator for that!
09:09 PM CaptHindsight: andypugh: temporarily driving a 2019 Fusion hybrid
09:10 PM andypugh: Ford Fusion or Autodesk Fusion?
09:10 PM CaptHindsight: i can't belive they actually use fake engine sounds to give you feedback while accelerating
09:10 PM CaptHindsight: Ford
09:10 PM Tom_L: hah
09:10 PM Tom_L: that's funny
09:10 PM Tom_L: we are so used to noises...
09:10 PM CaptHindsight: a funny hack would be to change the sound and pitch, to say a mosquito
09:11 PM andypugh: CaptHindsight: Can you turn it off? i suspect that you would find yourself turning it back on.
09:11 PM andypugh: You get a lot more than you think from the sounds your vehicle makes.
09:11 PM CaptHindsight: andypugh: we found some ECU hack to do it, but it's just a rental
09:11 PM Tom_L: menu to choose your engine noise?
09:11 PM CaptHindsight: I'd love a quiet car
09:12 PM andypugh: Here is an illustrative anecdote from my old boss.
09:13 PM andypugh: Back in the early 1990s Ford found a problem with an engine mount, and had to issue a recall (in Europe) for the Escort.
09:13 PM andypugh: Customers were sent a letter, they took the car back under warranty, the problem was fixed in 20 minutes or so, and they took the car home.
09:14 PM andypugh: The interesting thing was the feedback when they were surveyed. Two points “Like the extra power” and “fuel economy worse”
09:14 PM CaptHindsight: heh
09:14 PM CaptHindsight: how big was the original mount?
09:15 PM andypugh: But this was an engine mount. All that had changed was the engine noise. They were revving higher.
09:15 PM CaptHindsight: huh
09:16 PM andypugh: But very few noticed that the noise was different, they just subconciously drove the car differnely.
09:16 PM CaptHindsight: when this car starts it make no noise, it just says "Ready to drive" on the dash
09:16 PM CaptHindsight: getting 40mpg so far
09:16 PM cradek: doesn't "start", it boots
09:17 PM andypugh: Hi cradek. Was it you with the huge camper van thingy?
09:17 PM _unreal_: sup
09:17 PM CaptHindsight: there's even an animated graphic showing you where the power is going to a from
09:17 PM cradek: yeah I've got a bus thing
09:17 PM _unreal_: ziper, hi
09:18 PM cradek: winterized just in time this year
09:18 PM _unreal_: cradek, ?
09:18 PM CaptHindsight: we had flurries earlier today
09:18 PM andypugh: Have you looked at panels on top and an electic motor booster?
09:18 PM CaptHindsight: snow tomorrow
09:18 PM _unreal_: MUAHAHAHAHAHAH
09:18 PM _unreal_: CaptHindsight, its like 80 outside
09:18 PM _unreal_: here
09:18 PM CaptHindsight: about a 3 week fall this year
09:18 PM CaptHindsight: we had the AC on just 3 weeks ago
09:18 PM cradek: you mean to propel it? that seems implausible to me
09:19 PM cradek: it has panels that keep the (big 12v) batteries charged, which is nice
09:19 PM andypugh: I thought that this was interesting: https://www.youtube.com/watch?v=j1tcyEo2tQk
09:22 PM cradek: I hope one day we all run at least our house ACs on solar
09:22 PM CaptHindsight: biomass is full of crap :)
09:27 PM _unreal_: no its full of bio
09:27 PM _unreal_: GOD get it rigth
09:27 PM _unreal_: right
09:28 PM CaptHindsight: https://www.youtube.com/watch?v=5Q_6--XsIgA this needs more research
10:11 PM drdoc: hey, have any of y'all bought motors from STEPPERONLINE?\
10:11 PM drdoc: they have decent prices on their lower-current nema 23 motors
10:14 PM Tom_L: about average i think
10:14 PM Tom_L: not bad
10:14 PM Tom_L: i got some 570in/oz for ~33ish ea
10:15 PM drdoc: they have a 174in/oz on sale for $12
10:16 PM drdoc: cheap placeholder that fits the power supply and drivers I have now
10:16 PM drdoc: at ~3x the power
10:16 PM drdoc: 3x the power of the motors I have
10:17 PM Tom_L: but is that enough for what you need
10:17 PM drdoc: well, it may be all my router can really use
10:17 PM drdoc: it's not terribly stout
10:18 PM drdoc: hrrmmm
10:18 PM drdoc: lo0oks like they only have 3 left
10:18 PM drdoc: I *really* need more holding torque on Z, more than anything else
10:19 PM drdoc: that little 58in/oz nema 17 gets pretty hot trying to hold its ground
10:19 PM Tom_L: get drivers with idle current shutdown
10:19 PM drdoc: that was the next question
10:20 PM drdoc: I'm very under-employed right now, so "better, pretty cheap" wins over "best"
10:21 PM drdoc: Are the problems with the TB6600 drivers inherent, or just cheap manufacture?
10:21 PM Tom_L: i waited until i could get what i wanted as an end result
10:21 PM Tom_L: dunno, i don't use em
10:22 PM drdoc: heh
10:23 PM Tom_L: seem to be a choice for reprap so they're probably on the very cheap end
10:23 PM drdoc: yeah
10:23 PM drdoc: I won't be looking at Gecko for a good while, and decent performance would be a step up from the A4988s I have now
10:26 PM Elmo40: yeah. Geckos are pricey
10:26 PM Elmo40: but rock solid!
10:26 PM Tom_L: i use em
10:27 PM drdoc: I gotta remember that it's more toy than tool
10:28 PM drdoc: when it comes down to it, precision is a lot more important than speed or size
10:29 PM drdoc: what about the DM542 drivers?
10:30 PM drdoc: stepperonline's DM542S isn't a lot more expensive than the TB6600
10:31 PM drdoc: https://www.omc-stepperonline.com/digital-stepper-driver/dm542s.html
10:31 PM drdoc: oops
10:31 PM drdoc: dinner's on, later!
10:39 PM drdoc: 698iiiiiiiiiiiiiiiikjjjjjjjjj\

10:44 PM Tom_L: i'm guessing cat.
10:56 PM Elmo40: LoL
10:56 PM Elmo40: Tom_L, you have Geckos?
10:56 PM Tom_L: 203v
10:56 PM Elmo40: which models? what motors do you drive?
10:57 PM Elmo40: at what voltage?
10:57 PM Tom_L: https://www.geckodrive.com/g203v-digital-step-drive.html
10:57 PM Tom_L: 48v
10:57 PM Elmo40: where they simple to get setup?
10:57 PM Tom_L: they're good to something like 80v?
10:58 PM Elmo40: so it says
10:58 PM Tom_L: https://www.ebay.com/itm/3pcs-NEMA23-570OZ-IN-5A-3-8-DUAL-SHAFT-STEPPER-MOTOR/253223632606?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649
10:58 PM Tom_L: those steppers
10:59 PM Elmo40: what is your step rate?
10:59 PM Tom_L: running at about half current
10:59 PM Tom_L: ?
10:59 PM Elmo40: 1/4 stepping? 1/32 stepping? full steps?
11:00 PM Tom_L: those are set to 10 microsteps
11:00 PM Tom_L: but i think they feather out as the rpm changes
11:00 PM Tom_L: no jumpers for microstepping like on the leadshine etc
11:01 PM Elmo40: just reading about the 'morphing' it has.
11:01 PM Elmo40: "At a native ten microstep resolution ..."
11:01 PM Elmo40: i see it now.
11:02 PM Elmo40: you opted for 203V over the 201 line? any reasons?
11:02 PM Tom_L: bullet proof
11:03 PM Elmo40: i think their entire line is.
11:03 PM Tom_L: it has a few more 'safety' features
11:03 PM Elmo40: those look like nice steppers! for 3D printing they would be a tad overkill... ;-) But my next table top mill i think i'll order a set.
11:03 PM Tom_L: short circuit protection, overvoltage protection, overcurrent regulation, and an internal user-replaceable fuse
11:04 PM Tom_L: i wanted to be sure i could cut steel and not lose steps :)
11:05 PM Tom_L: while testing, the table touched the table mounted vise i have and instead of stalling it pushed the mill
11:05 PM Elmo40: into the spindle?
11:05 PM Tom_L: no, it moved the mill across the steel table
11:06 PM Elmo40: gotcha
11:06 PM Elmo40: so it has some torque to it... ;-)
11:10 PM Elmo40: would the G540 4-Axis unit be more lcnc user friendly? parport connection and everything.
11:11 PM Tom_L: i dunno if it would be more friendly, it's not quite as robust
11:11 PM Tom_L: i'm using mesa cards on mine as well
11:11 PM Elmo40: up to 3.5A, not bad.
11:11 PM Tom_L: yeah
11:12 PM Tom_L: the voltage isn't as high
11:12 PM Elmo40: and can run on 48V
11:13 PM Tom_L: would be on the top end of it's limit
11:14 PM Elmo40: true
11:14 PM Elmo40: is the 203V relatively silent?
11:14 PM net|: http://netpipe.ca/apps/testapp/widgets_wiggly.html got more gui work done, now that i have basic framework should be easy as pie
11:14 PM Tom_L: yeah
11:17 PM Elmo40: even with only 10 microstepping?
11:17 PM Elmo40: do you think that helps with a more smooth cutting speed? less stepper 'steps' being translated into your cuts?
11:18 PM Tom_L: https://www.youtube.com/channel/UCoG_JaILNz3Q-jBZ5MiK1dA/videos?view_as=subscriber
11:19 PM Tom_L: you can watch a few of those and listen for yourself
11:20 PM Tom_L: the spindle is a crap sherline spindle but i had it.
11:32 PM Elmo40: ever heard of the DQ542 driver? cheap chinese thing. looks like a gecko.
11:33 PM Elmo40: i dont have large motors. only ~2A ones that I want to drive at 24V (though i'll go up to 36 if I can)
11:33 PM Elmo40: also contains an internal fuse :-)
