12:39 AM chopper79: Evening
12:52 AM chopper79: Going to be setting up my spindle enocder this weekend. I need to set the spacing for the gear tooth sensors. I do not have an O scope so I was wondering if I could set the spacing using halscope on monitor the A and B phase to see the spacing? If not I have heard you can use LED to do the samr thing. Anybody have nay insight on this?
01:01 AM MacGalempsy: mark the spindle ans watch the mesa count in hal on one rotation
01:02 AM MacGalempsy: is it direct or geared?
01:02 AM chopper79: ok, what would I be looking for while watching it?
01:02 AM chopper79: It is directly mounted to the spindle cartridge.
01:02 AM chopper79: https://youtu.be/Wd9ZrgM2G94
01:03 AM chopper79: Here is a link to my poorly done video on what I am doing
01:03 AM MacGalempsy: ok. so fo you know the ppr or is that what your trying to find out?
01:03 AM MacGalempsy: fo = do
01:03 AM chopper79: I machined a 80 tooth gear so it would be 320ppr
01:04 AM chopper79: got it... I am constantly fat fingering keys myself.
01:04 AM MacGalempsy: quadrature?
01:04 AM chopper79: yes
01:04 AM chopper79: using 2 gear tooth sensors for encoder and then 1 more for index
01:04 AM MacGalempsy: ok. so in the ini you use 320x4
01:05 AM chopper79: correct.
01:05 AM XXCoder: had to use freeze frame trick to see whats going on your video. im way past shaky video limit
01:05 AM XXCoder: enough that my hands is little shaky
01:05 AM chopper79: sorry...it played fine on my end. Let me look at it again.
01:06 AM XXCoder: no its not your video
01:06 AM XXCoder: its me
01:06 AM XXCoder: I just pause video and use forward to see a frame each second or so
01:06 AM chopper79: got ya.
01:07 AM XXCoder: watched canadian borders tv show, very interesting show
01:07 AM XXCoder: talks about people and stuff entering cananda and they catch people trying to enter under shady poremises
01:08 AM XXCoder: and some inoccents with mistakes (like that guy who bought in bunch vacuum packed meat and didnt put in meat in customs paper)
01:08 AM MacGalempsy: after watching the vid, all i can say is good luck :)
01:09 AM chopper79: lol... I can not help but get the feeling of your srewed
01:09 AM chopper79: screwed
01:09 AM MacGalempsy: i thought you were using an actual encoder
01:10 AM chopper79: Nope... I would be done already if I was.
01:10 AM chopper79: Trying my hand at making my own setup for the spindle.
01:10 AM MacGalempsy: but you should be anle to wire your sensors into the mesa and work the same
01:10 AM MacGalempsy: 5v max
01:11 AM MacGalempsy: you will use inductive sensors?
01:11 AM archivist: time for a real scope
01:11 AM XXCoder: making your own encoder eh
01:12 AM chopper79: http://www.digikey.com/product-detail/en/allegro-microsystems-llc/ATS667LSGTN-T/620-1328-1-ND/2042758
01:12 AM chopper79: Those are the sensors I am using
01:12 AM chopper79: XXCoder: yes I am
01:12 AM archivist: wiring to ordinary inputs and using halsope can only be done at a slow speed
01:13 AM chopper79: archivist: I know I need to buy one
01:13 AM XXCoder: cool. I need to figure how to mount tach sensor to somewhere on spindle where it can read
01:13 AM chopper79: ok.. with that answer I will try to find someone who has a scope I can use.
01:14 AM chopper79: XXCoder: Here is by build thread https://forum.linuxcnc.org/30-cnc-machines/32122-1982-matsuura-mc-500v-retrofit?limitstart=0
01:14 AM XXCoder: cool. love reading build threads
01:15 AM * Wolf_ hates diy stuff
01:15 AM XXCoder: aw poor wolf
01:15 AM XXCoder: whats you make with your cnc?
01:15 AM chopper79: I am trying to document everything I am doing and then give my data, etc to the thread for others to use.
01:15 AM Wolf_: lol
01:16 AM chopper79: Wolf: whay do you hate DIY stuff?
01:16 AM chopper79: why
01:16 AM Wolf_: hate it right now cause I can’t figure out how to configure this stupid stepper driver
01:16 AM chopper79: oh
01:16 AM chopper79: what driver
01:16 AM XXCoder: if its tb6600 its quite strightforward
01:16 AM Wolf_: got a tmc2660 on a smoothie, uses spi to configure it
01:17 AM archivist: smooth..cough splutter, wot no linuxcnc
01:17 AM Wolf_: wanted to try something different
01:18 AM chopper79: I have been playing around with different choices myself. Keep coming back to lcnc
01:18 AM chopper79: I have not messed with the smoothie yet even though it is on my list.
01:18 AM chopper79: Have you seen this config page? http://smoothieware.org/advancedmotordriver
01:18 AM XXCoder: I want a smoothie, but definitely not for cnc router!
01:19 AM XXCoder: I want to try make delta
01:19 AM Wolf_: this is going on the laser
01:19 AM chopper79: I made a delta printer. Used RAMPS on it.
01:19 AM chopper79: Worked well then I decided to break it to make something else.
01:23 AM chopper79: Used carbon fiber rods with polished bearing balls on the end for the arms. The ball sat in concave neo mags to create the joints. Super smooth and could take apart and put back together real fast.
01:23 AM Wolf_: cool
01:23 AM chopper79: Lasers are cool also
01:24 AM XXCoder: heard ramps is kinda hard to use on deltas?
01:24 AM XXCoder: makes delta hard to configure
01:24 AM chopper79: I have a small K40 china fire starter in the garage.
01:24 AM Wolf_: laser should be fun, plan is for 100w RECI tube
01:24 AM chopper79: Need to change it to smoothie als.
01:24 AM chopper79: also
01:25 AM Wolf_: got a 2.5w blue laser to use in the mean time when doing setup/playing with the smoothie and laserweb
01:25 AM chopper79: deltas are a pain in the rear to configure I think. Like I said I broke it and made a standard printer. Delta was always being tuned...
01:25 AM chopper79: I like laserweb
01:26 AM chopper79: I am going to make a small pcb mill using smoothie. Figured it would be a fun small package to mess with.
01:28 AM chopper79: Really wish I could find a away to make a Pi work function with ethernet and lcnc. Would love to make a small controller.
01:28 AM Wolf_: part of the reason I went w/ the smoothie for the laser setup, simple setup, control board + laser psu
01:28 AM chopper79: I do not want to go BeagleBone. Not sure why but I just do not like it.
01:29 AM XXCoder: chopper79: maybe try CHIP
01:29 AM Wolf_: http://i.imgur.com/wlNAOW9.jpg so far looks pretty nice
01:29 AM XXCoder: im wondering about that too
01:29 AM chopper79: CHIP?
01:29 AM XXCoder: CHIP dont have parallel port for linuxcnc though
01:29 AM XXCoder: yeah by nextthing. I hate word model names
01:29 AM chopper79: I use ethernet anyway for my 7i92
01:29 AM XXCoder: it fails google test so hard
01:30 AM chopper79: Wolf: look cool
01:30 AM chopper79: So what is CHIP
01:30 AM XXCoder: its a small board computer
01:31 AM XXCoder: 12 bucks if I recall right
01:31 AM XXCoder: though may be too weak for linuxcnc
01:31 AM chopper79: wow..that is small
01:33 AM archivist: chopper79, look at the last few months mailing list, for a user messing with pi
01:33 AM chopper79: Would be the same issue on the CHIP as the Pi. Ethernet is ran through USB
01:33 AM CaptHindsight: the Pi has SPI
01:33 AM chopper79: Seen many post where that does not work for communicating to the 7i92 via ethernet.
01:34 AM CaptHindsight: the allwinner stuff has integrated ethernet but the video drivers are not open
01:34 AM CaptHindsight: but software rendering is speedy enough if you use 4 or more core devices
01:34 AM chopper79: I have a cubieboard 2 here. Have not tried it yet though. I like how it has sata connections on it etc.
01:35 AM CaptHindsight: the main problem is that you really have to know how to build kernels, tool chains and the video drivers or you run into the problems seen on the mail list
01:36 AM chopper79: Which I do not ..... so maybe that is why I have not tried it yet
01:36 AM CaptHindsight: we had LCNC on the cubie2 a few years ago, have to use LLVMpipe for video
01:37 AM chopper79: I have a BeagleBone and a Cubie Board. Tried machinekit, but said heck with it. Never tried the cubie yet, and I want to try a Pi but do not have one.
01:37 AM CaptHindsight: Axuis ran smooth until you had a 1920 x 1080 screen and tried to move it around quickly
01:37 AM chopper79: Getting ready to order a couple J1900 computers
01:37 AM CaptHindsight: the new Pi has open GPU drivers
01:37 AM chopper79: Maybe I will order a Pi while I am at it. Just o play around with it.
01:38 AM XXCoder: chop yep tiny lol
01:38 AM chopper79: My goal is to make a small control box that houses the pc, driver, etc all in one. All while keeping the size down
01:38 AM CaptHindsight: I'd say it would take a couple weeks full time to get a Pi working really well with LCNC along with accelerated graphics
01:38 AM XXCoder: though I wonder with its plenty of pinouts it might not need parallel port at all, though how to make linuxcnc use em dunno
01:39 AM chopper79: I want to get one of those CHIP now to just mess with it.
01:39 AM CaptHindsight: there are a bunch of broken tool chains for it
01:40 AM XXCoder: its cheap enough yeah. just go out one less time
01:40 AM chopper79: If I get a Pi or a CHIP it will be for my own personal enjoyment or headache.
01:40 AM CaptHindsight: with preempt on the cubie2 I think we had ~70Kus for max jitter
01:40 AM chopper79: nice
01:41 AM chopper79: That is what I will be using... Preempt Rt and ethernet to a 7i92.
01:41 AM chopper79: or a 7i76e
01:41 AM CaptHindsight: er 70uS not 70k uS
01:41 AM chopper79: I figured
01:42 AM Cromaglious_: chopper79, J1900 are those ITX computers?
01:42 AM chopper79: https://www.newegg.com/Product/Product.aspx?Item=N82E16856164024&cm_re=j1900-_-56-164-024-_-Product
01:43 AM chopper79: Little ones
01:43 AM chopper79: Mount to the back of a monitor
01:43 AM Cromaglious_: I'm running an Atom 1.6Ghz G945 board parallel port.. working on a Arduino mega ethernet BOB
01:43 AM chopper79: nice
01:44 AM chopper79: wish I had the understanding of PC stuff to figure these things out. I know enough to get myself into trouble.
01:44 AM Cromaglious_: love vesa mounts.. Right at the moment mine is under the monitor... once I get everything squared away it goes back onto the monitor
01:44 AM Cromaglious_: Mini-box.com with the 20x2 LCD screen on the front
01:45 AM Cromaglious_: PCI risers with a PCI wifi card in them (I have 2)
01:45 AM chopper79: I like things not cluttered so that is why I am so interested in a SBC with all drivers, BOB etc in a small enclosure to sit on the bench top.
01:45 AM CaptHindsight: chopper79: the headache with lots of the ARM boards is missing source
01:45 AM chopper79: I can not stand all the boxes, monitors, etc all over.
01:46 AM CaptHindsight: they might say that it's in some repo but then it's not really the driver they used to build the binary only working kernel
01:46 AM chopper79: CaptHindsight: That is what I am finding. The most complete is the Machinekit.
01:46 AM Cromaglious_: the PI is looking interesting.. a 3 running at 1.4Ghz with a parallel port BOB hanging off the gpio using level converters looks interesting
01:47 AM Wolf_: I like the mini itx stuff for that reason, its still small and don’t really need to mess with it much to get linux running on it
01:47 AM CaptHindsight: and unfortunately the TI board has no open gpu drivers so video is sssssllllloooowwww
01:47 AM chopper79: Wolf: I agree
01:47 AM XXCoder: I wonder how cheaop itx can be and still under 15k jitter
01:48 AM Cromaglious_: wolf hehe.... my board won't boot of USB drives Grrrrrrr and it took me 4 days to get 4.9.13 booting on it
01:48 AM chopper79: If I was a electroics guru I would design and build a purpose built SBC about 3.5" x 3.5" strictly for running LCNC
01:48 AM CaptHindsight: aren't the Intel mini-itx boards under $50 or $60
01:48 AM chopper79: Limited market but would love to do it
01:48 AM Wolf_: took me 3 days to set mine up, but in that time I cooked 3 kernels on it lol
01:48 AM Cromaglious_: XXCoder, it you run it headless with no X, pretty damn cheap
01:49 AM XXCoder: no X linuxcnc?
01:49 AM Cromaglious_: love the 14hour kernel compile times
01:49 AM XXCoder: love the infinity text scrolling
01:49 AM chopper79: I have used X when using the Beagle bone and machine kit.
01:49 AM XXCoder: cant remember when I last compiled kernel but damn it was long.
01:49 AM Cromaglious_: he was talking about getting jitter down
01:50 AM CaptHindsight: the other problem with the Pi is long term availability
01:50 AM XXCoder: crom honestly my 12 year old pc has 15k jitter, below "very good" 25k
01:50 AM Cromaglious_: before this week... my last kernel was probably 10 years ago
01:50 AM CaptHindsight: and I would not build a product around it
01:50 AM chopper79: I agree
01:50 AM XXCoder: while laptop lol 250k jitter'
01:50 AM CaptHindsight: unless it's some cheap thing for poopstarter
01:51 AM chopper79: XXCoder: sounds like my dev laptop. All I use it for is GUI stuff on LCNC. The jitter is about 499K
01:51 AM chopper79: haha
01:51 AM XXCoder: fancy
01:51 AM CaptHindsight: I don't think Broadcom will sell you the silicon on the Pi3
01:51 AM Cromaglious_: my atom is around 35K with only linuxcnc on it... hook the network up... 50-80k
01:51 AM XXCoder: but seriously no display?
01:51 AM CaptHindsight: so you can't lverage that software for you own well designed product
01:52 AM chopper79: CaptHindsight: Not for kickstarter.
01:52 AM XXCoder: or does it output to led numbers display, leds and so on?
01:52 AM Cromaglious_: XXCoder, I've had headless boxes run for year! You just ssh into them
01:52 AM Cromaglious_: or worse... serial terminal
01:52 AM XXCoder: ya had one before but to control cnc machine? thats new to me
01:52 AM chopper79: I ssk into mine and still hated it.
01:52 AM chopper79: ssh
01:52 AM Wolf_: my itx http://i.imgur.com/fIDC0aZ.jpg
01:53 AM Cromaglious_: I had a Dec VT210 in the bedroom hooked to my house server in the next room
01:53 AM XXCoder: hmm got idea
01:53 AM XXCoder: get itx but fit it inside my orginial computer
01:53 AM chopper79: My vision will come true one day. Need to find me a bunch of smart people around my town to hang out with.
01:53 AM XXCoder: penty of room for tons stuff, like pwm board, BOB, 3 tb660s, and all psus in it
01:54 AM Cromaglious_: love those TB6600's
01:54 AM XXCoder: my computer uses tiny 8 gb ssd lol
01:54 AM XXCoder: bought it cheap
01:54 AM Cromaglious_: 680GB 2.5 HD
01:55 AM Cromaglious_: distributed backups...
01:55 AM Wolf_: smoothie is coming along at least
01:55 AM XXCoder: I didnt see any need to have larger ssd
01:55 AM XXCoder: linuxcnc only needs 4 gb, and I decided to grab 8 gb
01:55 AM XXCoder: 6 gb room left if I recall
01:55 AM Wolf_: my itx has a 60gb ssd, I think it was the cheapest I could find lol
01:55 AM Cromaglious_: well the VA is sure taking thier time... and now my wife isn't working because of cancer right now...
01:56 AM XXCoder: Wolf_: it was hmm 20 bucks? or was it 40
01:56 AM Cromaglious_: so we are living on around $1000 a month...
01:56 AM Wolf_: iirc $38
01:56 AM Cromaglious_: my 680GB was $32
01:56 AM XXCoder: interesting, didnt find 60gb ssd for 38 bucks or would buy that
01:56 AM Cromaglious_: though it's a sata 2.5" Hd
01:56 AM XXCoder: though oif it was 20 bucks it wouldnt matter
01:57 AM Cromaglious_: still trying to get a real smoothie board...
01:58 AM XXCoder: its 110 bucks iirc?
01:58 AM Wolf_: http://i.imgur.com/WXnJtwz.jpg <$$$
01:58 AM chopper79: Well I am off to bed... Good night all
01:58 AM Cromaglious_: $140 I think
01:58 AM Cromaglious_: 4 channel
01:58 AM Cromaglious_: nite chopper79
01:59 AM Cromaglious_: and the voltage regulator
01:59 AM XXCoder: wolf nice
01:59 AM XXCoder: smoothie eh
01:59 AM XXCoder: I see 3 more slots for stepgen and connectors
01:59 AM Wolf_: yep, x5 gt
02:00 AM XXCoder: nema34s
02:00 AM Wolf_: 23s
02:00 AM XXCoder: really? I guess I figured scaling wrong
02:00 AM Wolf_: https://shop.uberclock.com/collections/smoothie if i was doing it over again
02:01 AM XXCoder: pretty long 23s, I guess oz/in would be double or more mine
02:01 AM XXCoder: mines 400 or so oz/in
02:01 AM Cromaglious_: I'm looking at those JMC-motor integrated hybrid steppers... $110ush for a 142ozin Nema23
02:01 AM Wolf_: 420oz/in
02:01 AM Cromaglious_: 3Nm
02:01 AM Cromaglious_: 142 are 1Nm
02:01 AM XXCoder: honestly I dont belive mine is 400 oz/in
02:01 AM XXCoder: its pretty weak
02:02 AM Cromaglious_: my current ones are like 42ozin
02:02 AM Wolf_: these are 4 3/8”
02:02 AM Cromaglious_: gutless... only take 2.5amp at 32v
02:03 AM Wolf_: just the frame not counting shaft
02:03 AM XXCoder: 110 N/cm lemme convert
02:04 AM Wolf_: 4.2A and i run them at 40v
02:04 AM XXCoder: ah thats 155 oz/in, I guess I messed p conversion or misrememebred
02:04 AM XXCoder: now that makes more sense
02:04 AM XXCoder: wolf how much A yours need?
02:04 AM Wolf_: 4.2A
02:05 AM XXCoder: heh not surpising, mine is 2a
02:05 AM Wolf_: is marked on them
02:05 AM Wolf_: on my mill I’m running them at 2A peak lol
02:05 AM XXCoder: I doubt I need stronger steppers for my current router, but big one yea
02:06 AM XXCoder: it says 3a max
02:06 AM XXCoder: psu is 350w/24v
02:06 AM Wolf_: i’ll be getting 200oz for the final laser build
02:06 AM XXCoder: wonder if theres enough power to feed all steppers 3a
02:07 AM XXCoder: or is it unwise to max em out
02:07 AM Wolf_: i tend to over size and run lower current
02:08 AM Wolf_: runs them cooler
02:08 AM XXCoder: 14A max out of psu so I guess yes
02:09 AM XXCoder: 3A, 3 of em = 9A plus some more used by tb6600s and BOB
02:09 AM XXCoder: meh 2a seemed fine
02:09 AM Wolf_: drivers + bob not worth counting lol
02:10 AM XXCoder: ya guessed those dont use all that much power.
02:11 AM Cromaglious_: These are sweet! http://www.ebay.com/itm/like/262565303249?lpid=82&chn=ps&ul_noapp=true
02:11 AM XXCoder: yeah!
02:11 AM XXCoder: dont think its worth it for my machine
02:11 AM Cromaglious_: closed loop
02:11 AM Wolf_: this whole smoothie is pulling 0.08A @ 24v right now
02:11 AM Cromaglious_: Iwant them for my shitty 3040
02:12 AM XXCoder: crom one thing I wondered is that it has connectors hats hard to shei;d
02:12 AM XXCoder: WTF??
02:12 AM XXCoder: nema17s, 20 if em for 4.5 bucjs
02:12 AM Wolf_: huh
02:12 AM XXCoder: dont need but dang cheap lol
02:12 AM Cromaglious_: hmm?
02:12 AM XXCoder: http://www.ebay.com/itm/LOT-Nema-17-Stepper-Motor-Bipolar-84oz-in-59Ncm-CNC-3D-Printer-Reprap-Robot-MAX/262867898135
02:13 AM Wolf_: not that I need 20...
02:13 AM XXCoder: ah for ONE
02:13 AM XXCoder: nm guys false alarm
02:13 AM Wolf_: $119.95 for 20
02:13 AM XXCoder: its actually misleading, since -select- is 4.5 bucks, but one is bit over 10 bucks
02:14 AM Cromaglious_: extruder tip is the $4.50 price
02:14 AM XXCoder: crom I found a 2 ncm same thing but cheaoer
02:15 AM XXCoder: http://www.ebay.com/itm/NEMA23-2Nm-283oz-in-Integrated-open-loop-stepping-motor-36VDC-JMC-iHS57-36-20/262623157933
02:15 AM XXCoder: oh open loop
02:16 AM Cromaglious_: 2nm for 90 + 24 shipping closed loop http://www.ebay.com/itm/NEMA23-2Nm-283oz-in-Integrated-Closed-Loop-Stepper-motor-36VDC-JMC-iHSS57-36-20-/262565317443?hash=item3d221ccb43:g:QsIAAOSwbsBXpUtI
02:16 AM XXCoder: yeah 2 nbucks more. I was double confirming because of earlier 2 mistakes lol
02:16 AM Cromaglious_: NO MORE LOST STEPS! did I mention no more lose steps?
02:17 AM Cromaglious_: if it gets too far out of whack... it'll alarm
02:17 AM XXCoder: do your nemas has flat spot on shift?
02:17 AM Cromaglious_: you can wire that into a limit circuit
02:17 AM XXCoder: mine dont and its annoying
02:17 AM Cromaglious_: flat spot?
02:18 AM XXCoder: I need to take it out, grind flat spot and bolt coupler on
02:18 AM XXCoder: yeah so set screw is more secure
02:18 AM Cromaglious_: hmm all mine have flat spot
02:18 AM Cromaglious_: but the grinder is handy if I need it
02:18 AM XXCoder: ya need to find mine
02:19 AM XXCoder: or maybe buy another nema23s :P
02:19 AM Deejay: moin
02:19 AM Cromaglious_: morning Deejay
02:20 AM Cromaglious_: wifey's home! back from storming the castle (Playing D-n-D)
02:20 AM XXCoder: never was any good on that
02:21 AM XXCoder: played few of those then decided not for me
02:22 AM Cromaglious_: I played back in high school... chess was a better game for me
02:23 AM XXCoder: no chess club
02:23 AM Cromaglious_: heh half the chess club was also wrench heads...
02:24 AM Cromaglious_: play chess and talk hot rods
02:24 AM XXCoder: deaf school was pretty badly underfunded back then
02:24 AM XXCoder: so not much to do
02:24 AM XXCoder: had nice wood shop but then mr hammer had a heart attack. my class was last one
02:24 AM XXCoder: so I took basic wood shop class but not advanced
02:25 AM Cromaglious_: oh yeah... audio deprived.. My Grandma lost her hearing during the Blitz in London during WWII
02:25 AM XXCoder: nah I never lost hearing
02:26 AM XXCoder: I have been deaf since before I am day zero old
02:26 AM Cromaglious_: I have tinnitus which is getting worse as I get older..
02:27 AM XXCoder: I'm quite thankful its rare for me
02:27 AM Cromaglious_: how good does bone conduction work for you?
02:27 AM XXCoder: my good friend had tinnitus for pretty much his entire life after his 20s not too sure if earlier
02:28 AM XXCoder: he died at late 70s
02:28 AM XXCoder: he hears nothing else, being deaf
02:28 AM XXCoder: I imange that makes it much more annoying
02:28 AM XXCoder: dunno, dont matter anyway my hearing centers never really developed
02:28 AM Cromaglious_: yep... any background noise and I can't understand people
02:33 AM XXCoder: other friend of mine has unusual case'
02:33 AM XXCoder: 100% hearing, but hes brain damaged in hearing centers
02:33 AM XXCoder: so he was losing ability to understand what sounds meant
02:33 AM XXCoder: so he is effectively deaf now, though he can hear everything
02:33 AM XXCoder: he cant even tell what direction sounds come as that needs processing also
02:33 AM Cromaglious_: I can understand that
02:33 AM SpeedEvil: i wonder how much help structured training might provide.
02:33 AM SpeedEvil: Retraining the remaining brain structures as to what sounds are like rather than trying to learn them in an unstructured chaotic envirionment where you don't know when or what the sounds are and have no reinforcement
02:33 AM XXCoder: good question, we are discussing sense I dont have heh
02:33 AM Cromaglious_: I'd presume you can feel vibrations... I wondering what frequency range you can detect...
02:33 AM XXCoder: crom good question, I tried music and stuff it was all meaningless to me. thats why I suspect im tone deaf also
02:33 AM XXCoder: but hard to prove
02:34 AM Cromaglious_: more like a motor with a out of balance weight on in... if you put your hand on it... can you guess rpm
02:35 AM XXCoder: yea can feel stuff like that, I can tell if cnc is having a really bad cut
02:35 AM XXCoder: or resourance issues
02:36 AM XXCoder: but its less sensive that people can hear, so I could miss something sometimes
02:36 AM XXCoder: like that time tool was really worn it wasnt vibrating much as usual but endmill was shot lol
02:38 AM Cromaglious_: I worked at the firing range.. we wore earplugs and ear muffs over the ears. We could feel the gunshots sound wavefront hit us and tell direction from feel.
02:38 AM XXCoder: ugh that'd be bad for me 10 years ago
02:39 AM XXCoder: I still remember working next to stomper
02:39 AM XXCoder: I felt each time it cut. boom. boom. boom
02:39 AM XXCoder: even when its stamping thin alum sheet
02:40 AM Cromaglious_: I wonder if you can put a long screw driver against something and put your thumb on in and lean you head on your thumb if you get a better feeling of the vibration. Bethoven did something like that
02:42 AM Cromaglious_: you don't fall down so your balance part of the ear is working to a degree
02:42 AM XXCoder: well I cheat somewhat on that
02:42 AM Cromaglious_: visual clues?
02:42 AM XXCoder: yeah
02:42 AM XXCoder: but not too bad
02:43 AM XXCoder: deaf seem to always have traces of hearing
02:43 AM XXCoder: im one of rather rare exception
02:43 AM Cromaglious_: the snail thingy must be totally FUBAR on you
02:44 AM Cromaglious_: cochlear
02:45 AM XXCoder: it bypasses some stuff so it might make hearing work for me, maybe
02:45 AM XXCoder: pointless anyway lol
02:47 AM Cromaglious_: well try using a screw driver to conduct vibrations from the cnc to some bone near your ear. when I do that.. I can hear it, I can feel it, I can see it as well
02:48 AM Cromaglious_: if I put it on my temple it shakes my eyes
02:48 AM XXCoder: lol sounds risky but yeah know of that
02:48 AM XXCoder: didnt think of using it for cnc machines ll see later
02:49 AM Cromaglious_: some things I can't feel with my fingers, but I can feel it at my head. The fluid in the balance tubes also jiggles...
02:50 AM Cromaglious_: I put the screw driver on the frame, or on the intake manifold nowhere near rotating parts. metl engine and frame conduct akit if noise
02:51 AM Cromaglious_: alot of noise
02:53 AM Cromaglious_: noise is just vibrations of air... get rid of the air and feel it with skin, eyeballs, your brain shaking, ...
02:54 AM Cromaglious_: on a cnc do it on the front of the frame of the machine, on the gantry side from the side so a gantry rapid doesn't shove it into your head.
02:54 AM XXCoder: lol I run cell 2 mills chugging all day and night
02:54 AM XXCoder: cnc router is one at home
02:55 AM XXCoder: and yeah I have BIG rule of knowing and avoiding all ponental impacts and crushes
02:55 AM XXCoder: I used to run a GIANT cnc rputer
02:55 AM XXCoder: one big enough to park car on
02:55 AM Cromaglious_: squash you flat kind eh?
02:56 AM XXCoder: very much so
02:56 AM XXCoder: once a while it sprays me with chips.
02:56 AM Cromaglious_: since I blew this laptop out with the air compressor.. it's been running so much cooler...
02:56 AM XXCoder: i move out of way, though usually distance means it dont cut
02:57 AM XXCoder: ah blowing on electics to make it work is good ol' tradition
02:57 AM Cromaglious_: 162.1f
02:57 AM Cromaglious_: with 80PSI of compressed air
02:58 AM XXCoder: wow strong blowjob eh ;)
02:58 AM Cromaglious_: lots of fluff came out
02:58 AM Cromaglious_: yep
02:58 AM Cromaglious_: oh look it's almost 0 dark 30...
02:59 AM Cromaglious_: bedtime for bonzo
02:59 AM XXCoder: aww heh
02:59 AM XXCoder: night
02:59 AM Cromaglious_: nite nite
05:03 AM XXCoder: https://www.aliexpress.com/item/Encoder-CJMCU-111-rotary-encoder-code-switch/32761484465.html
05:03 AM XXCoder: not bad
05:03 AM XXCoder: one to select step sizes and one to select axis
05:10 AM XXCoder: https://www.aliexpress.com/item/Brand-New-Wireless-handwheel-Mach3-MPG-Pendant-Handwheel-for-CNC-Router-Mac-Mach-3-4-Axis/32701429753.html
05:10 AM XXCoder: theres cheaper models but loks ehh
05:30 AM jthornton: morning
05:31 AM XXCoder: hey jthornton
05:32 AM XXCoder: I was wondering about pendants
05:32 AM XXCoder: it'd be nice to easily control machine
05:32 AM XXCoder: keyboard sucks
05:32 AM XXCoder: you have one?
05:34 AM jthornton: https://www.aliexpress.com/item/Ith-10A-Ui-660V-2-Position-On-Off-4-Screw-Terminal-Rotary-Selector-Switch-2Pcs/32764667140.html
05:34 AM XXCoder: whats numbers on connectors refer to?
05:34 AM XXCoder: and 2 position?
05:35 AM jthornton: opps thought it was a 4 postion
05:35 AM XXCoder: whats pendant would use to connect?
05:36 AM jthornton: you looking for a pendant with a lcd screen?
05:37 AM jthornton: https://www.aliexpress.com/item/THGS-3P4T-3-Pole-4-Position-Single-Wafer-Band-Selector-Rotary-Switch/32719538601.html
05:37 AM XXCoder: maybe I found one HB04 model
05:38 AM XXCoder: lol that nut looks just bad
05:38 AM XXCoder: https://www.aliexpress.com/item/New-HB04-Wired-USB-Handwheel-MPG-Pendant-For-Mach3-CNC-3-4-Axis-router-machine/32309979069.html
05:38 AM jthornton: you should see the washers on my 3 in 1 from grizzly
05:38 AM XXCoder: but its usb, I have no idea if can make work with linuxcnc.
05:39 AM XXCoder: https://www.youtube.com/watch?v=HiCpUB6TpdA
05:40 AM jthornton: I have a usb joypad on my plasma
05:40 AM XXCoder: https://www.youtube.com/watch?v=q7aLiMDHQrM
05:40 AM XXCoder: this old tony
05:40 AM jthornton: hmm that is Dewey's video
05:42 AM XXCoder: pretty slow
05:42 AM jthornton: http://linuxcnc.org/docs/2.7/html/man/man1/xhc-hb04.1.html
05:43 AM XXCoder: not bad
05:44 AM jthornton: I might get one for my plasma table
05:45 AM XXCoder: it has probe z
05:45 AM XXCoder: nice if I ever get probe
05:45 AM minibnz: oh dang i just blew up my mesa card :( stay wire with 24v met the gpio pins.. not happy Jan...
05:45 AM XXCoder: ow
05:46 AM minibnz: the card is recognised by the pci bus but wont toggle any bits. they wont change...
05:46 AM jthornton: ouch, which card
05:46 AM minibnz: 6i24
05:48 AM XXCoder: HMM https://www.aliexpress.com/item/CNC-Router-Tool-for-Engraving-Machine-Setting-Auto-Check-Device-for-Z-Axis/32323239497.html
05:49 AM minibnz: that will be $200+ au once i convert and add shipping..
05:49 AM minibnz: must cover that terminal in heatshrink...
05:49 AM minibnz: at the very least..
05:49 AM XXCoder: what happened?
05:50 AM jthornton: what is the conversion rate
05:51 AM jthornton: I have them in stock and First Class flies on the same plane as priority
05:51 AM minibnz: was trying to connect my coolant pump and didnt want to power down.. had one wire in its home (the high side of the mosfet) then the other waire wouldn't go into its home, so i let it go to adjust my vision and the machine reset.. then it wont wort..
05:51 AM minibnz: 1 : 075
05:52 AM minibnz: $140ua = $185au add $20-30au shipping and there we are $215au..
05:53 AM XXCoder: :( is it repairable?
05:53 AM jthornton: dang I hate when that happens
05:54 AM jthornton: https://mesaus.com/index.php?route=product/product&path=63&product_id=62
05:56 AM minibnz: i probably could unsolder the fpga chip and replace just that but i dont think i will get a chip on its own any cheaper than buying the whole card.
05:57 AM minibnz: and then if i do get the chip and thats not the problem then i am definitely behind the 8ball..
05:58 AM minibnz: element14 has what looks like the chip listed at $147au
05:58 AM minibnz: 6-7days delivery
05:59 AM jthornton: that's almost the card
05:59 AM minibnz: not worth the chance as much as i like to repair rather than replace
06:00 AM minibnz: hmmm digikey have the chip listed as $25us
06:00 AM XXCoder: jt the demo at near end of old tony video shows pitfalls
06:01 AM XXCoder: ow
06:01 AM jthornton: which one?
06:01 AM minibnz: XC6SLX16-2FTG256C
06:01 AM XXCoder: hb05
06:01 AM XXCoder: er hb04
06:01 AM XXCoder: he spins few times and machines keep moving after he stops till supposely arrived
06:01 AM minibnz: oh its a bloddy BGA.. that i cannot replace by my hand and would have to pay someone $50au to do that properly..
06:02 AM XXCoder: BGA?
06:02 AM jthornton: I can do that with any MPG
06:03 AM XXCoder: he adjusted something and it runs better
06:03 AM XXCoder: autocrapons shits on that time so cant figure what he did
06:04 AM minibnz: ball grid array.. these chips have solder balls under neath them, to replace them its a bitch, the assembly house i used to work for uses a fiberoptic camera to inspect all the pins and make sure they are placed correctly
06:05 AM minibnz: oh wow.. thats a bit rude..$260australian on the mesa site.. $55us shipping.. and that was the cheapest option...
06:05 AM minibnz: DANG!!! now where is that heatshrink..
06:05 AM jthornton: my shipping is better
06:08 AM XXCoder: jt can you check video at that point? im not sure what he did to improve response time
06:10 AM minibnz: jthornton oh didnt realise your site was a different one.. dang..
06:11 AM minibnz: i went thru mesanet.com
06:11 AM XXCoder: whats other cheaper site than aliexpress?
06:11 AM jthornton: yes I'm a Mesa dealer
06:11 AM XXCoder: banggood ah yes
06:12 AM minibnz: next time..
06:13 AM minibnz: oh today has been an expensive day.. i just dropped 250 on the new card.. and earlier today i dropped 700 on some watercut parts to make my tool pallet and they need touching up.. thats what i was doing when i decided to re-connect the coolant..
06:13 AM jthornton: XXCoder: I can't tell what he did but iirc ilowpass or something I used
06:13 AM XXCoder: hmm ok
06:13 AM minibnz: guess i will have to work on the other parts of the pallet..
06:13 AM XXCoder: wow.
06:13 AM XXCoder: banggood has bette cnc stuff
06:14 AM XXCoder: more parts vs whole machines
06:14 AM jthornton: yea ilowpass
06:14 AM minibnz: oh and i still need to find a supplier that will sell me a timing belt to replace the one on my Z axis i stripped some teeth off it by having the gibs locked
06:15 AM jthornton: http://paste.ubuntu.com/24157216/
06:15 AM XXCoder: ilowpass is a orogram?
06:15 AM jthornton: it's a hal component
06:16 AM XXCoder: oh
06:16 AM XXCoder: cool
06:16 AM jthornton: the paste is my BP knee mill
06:17 AM jthornton: I've bought stuff from Digikey and other suppliers to include in international shipments to help guys out
06:17 AM XXCoder: 50 drills for 3 bucks
06:17 AM XXCoder: yeah I would never run out of drills lol
06:17 AM XXCoder: http://www.banggood.com/50PCS-11_522_53mm-HSS-Titanium-Coated-High-Speed-Steel-Drill-Bit-Set-p-1001864.html
06:17 AM XXCoder: its probably not hss nor titanium coated
06:18 AM jthornton: get some play-doe and make a porcupine
06:18 AM XXCoder: probably fine for wood
06:20 AM XXCoder: know whats strange though?
06:20 AM XXCoder: no pendants
06:20 AM XXCoder: tons parts but not that
06:20 AM jthornton: Note:
06:20 AM jthornton: 1.Please allow 1-3mm error due to manual measurement. please make sure you do not mind before you bid.
06:20 AM jthornton: 2.Due to the difference between different monitors, the picture may not reflect the actual color of the item.
06:20 AM XXCoder: 1-3mm?
06:20 AM minibnz: hahhhahaha
06:20 AM jthornton: lol
06:20 AM XXCoder: 1mm drill + 3mm error
06:20 AM XXCoder: = 4mm free drill! or maybe -3mm drill LOL
06:21 AM minibnz: so you might get a zero mm drill bit by that measurement..
06:21 AM gregcnc: 3mm-3mm means you get an empty box
06:23 AM jthornton: never could find the router myfordboy has on banggood
06:23 AM XXCoder: no 2020 there at banggood either. aw
06:23 AM XXCoder: jt its on banggood
06:23 AM XXCoder: http://www.banggood.com/Triaxial-Desktop-DIY-CNC-Micro-Engraving-Machine-Assembling-Kits-p-1055377.html?rmmds=search
06:23 AM XXCoder: first one I found
06:24 AM jthornton: lol I was searching for router
06:24 AM XXCoder: http://www.banggood.com/search/elksmaker/0-0-0-1-3-45-0-price-0-0_p-1.html?sortType=asc all of same brand
06:25 AM XXCoder: weird guy got it for $100
06:27 AM XXCoder: http://www.banggood.com/0_3mm-Tool-V-shape-Carbide-PCB-Board-Engraving-Bits-CNC-Router-p-909752.html
06:27 AM XXCoder: is that good for cnc router use?
06:27 AM XXCoder: oh pcb
06:28 AM minibnz: im building a 5 axis mill for my brother to make jewellery moulds.... using up all my old parts i have kicking around.. had to buy a few bits so far im $200 into it and have enough parts to get a start.. aiming for a 50mm cubed working area..
06:29 AM XXCoder: nice
06:29 AM minibnz: torn on how to actually machine the wax, i am contemplating melting the wax with a needle and suckit away instead of grinding it or cutting it with a cutter.
06:29 AM XXCoder: I was thinking about mold for pewler casting
06:29 AM XXCoder: or some low temperate metal
06:29 AM XXCoder: zinc>?
06:30 AM minibnz: this is for lost investment casting, make a wax positive of what you want and set it in porous plaster then pour in metal and suck it into the mould
06:30 AM minibnz: smash off plaster and you have a gold/plat/silver ring
06:31 AM minibnz: he is currently paying someone $150au to machine them for him.
06:32 AM minibnz: wonder if i could use a ultrasonic vibrator to oscillate a cutter instead of spinning one..
06:32 AM XXCoder: borrow lady one
06:32 AM minibnz: heheheehhehe
06:33 AM XXCoder: honestly dunno
06:33 AM minibnz: i was passing the tool shop today so i stopped in a lashed out $16au on two D cutters that have a 0.1mm tip..
06:34 AM minibnz: looking at them got me worried about runout.
06:34 AM minibnz: so if they dont spin but simply vibrate up and down (maybe a little side to side) it might cut the material
06:34 AM minibnz: and it will be much quieter than a spindle of any sort.
06:35 AM XXCoder: unless you has dogs cats or birds
06:36 AM minibnz: just crank it way up past 44khz and you wont anoy too many critters.
06:38 AM jthornton: sun is just coming up and it snowed last night about 1 inch
06:39 AM XXCoder: weird
06:39 AM XXCoder: 500mm is 7 bucks each, shipped
06:39 AM XXCoder: 600mm is 35 bucks each, shipped.
06:41 AM XXCoder: 2 of 500mm, connected together = 1000mm or 1m tall HMMMM
06:41 AM XXCoder: so much savings.
06:41 AM sync_: minibnz: a proper high speed spindle will make no noise at all
06:41 AM jthornton: what is 500mm?
06:41 AM XXCoder: I certainly dont feel much vobration with my spindle.
06:42 AM XXCoder: when cutting can feel it a little, though 1/16 ball em at 12000 rpm has very little cut per tooth
06:42 AM XXCoder: jt 2020 extrusions
06:42 AM jthornton: ah
06:43 AM XXCoder: 2040 is barely more money
06:47 AM jthornton: I guess I should get dressed and go pack up todays shipments
06:48 AM XXCoder: yay
06:49 AM jthornton: https://www.youtube.com/watch?v=GPrh8KPM4Zc
06:50 AM XXCoder: witchcraft!
06:50 AM XXCoder: yah im just ehh about how close connectors is to mtal case
06:51 AM XXCoder: but then he has 100 times more experence than I do on building.
06:51 AM jthornton: he does some amazing stuff
06:51 AM XXCoder: heyy his switch is same as I have, I guess it should be fine
06:51 AM XXCoder: its rated to 125v 10a
06:52 AM XXCoder: so 1250 watts whuich is way more than my machine uses
07:17 AM jthornton: dang I can't remember what I had to do to build a master deb... debuild complains about Package libxenomai-dev exists, but information about its source package is not available.
07:19 AM jthornton: hmm I enabled backports but that didn't seem to fix it... must have done something else
07:20 AM XXCoder: did you use parameter?
07:20 AM XXCoder: like --nowhatever?
07:20 AM jthornton: debian/configure uspace ; debuild -uc -us
07:21 AM jthornton: ./configure --with-realtime=uspace --enable-build-documentation=html
07:23 AM jthornton: hmm maybe I have to make first... my notes are fuzzzy on that
07:24 AM Tom_L: use fuzzy logic
07:25 AM jthornton: I have fuzzy logic sometimes lol
07:29 AM Victor is now known as Guest10984
07:29 AM Guest10984 is now known as Granath
07:36 AM JT-Shop: you get any snow over your way Tom?
07:36 AM XXCoder: 550mm :D barely increase price.
07:38 AM skunkworks: 33us over night
07:44 AM Tom_L: nope, it's dry here
07:45 AM JT-Shop: just started snowing again
07:45 AM Tom_L: 36
07:47 AM Tom_L: looks like KC might be getting some
07:49 AM XXCoder: guys https://www.aliexpress.com/store/product/T-slot-L-type-90-degree-EU-standard-2020-aluminum-profile-Inside-corner-connector-bracket-with/834897_32707599936.html
07:49 AM XXCoder: how do those hold 2 2020s together?
07:50 AM Tom_L: looks like they would slide in the extrusion and screw on both sides
07:50 AM MacGalempsy: good morning
07:51 AM XXCoder: wb
07:51 AM MacGalempsy: thx
07:52 AM MacGalempsy: how about using a L-bracket?
07:54 AM XXCoder: nah found good one
07:54 AM XXCoder: https://www.aliexpress.com/item/50pcs-L-shape-90-Degree-Inside-Interior-Corner-Connector-Joint-Bracket-with-M4-Grub-Screw-2020/32690612794.html
07:56 AM MacGalempsy: cheap price
07:56 AM XXCoder: yeah.
07:56 AM XXCoder: I decided to build a cnc controller box using 2020s
07:57 AM XXCoder: more money than regular box but why not
07:57 AM XXCoder: https://www.aliexpress.com/item/TL-Smoother-addon-module-for-3D-pinter-motor-drivers-free-shipping/32776922807.html
07:57 AM XXCoder: I wonder if thats worth it
07:58 AM MacGalempsy: what does it do?
07:58 AM XXCoder: its primarily for 3d printers, it cleans stepper signal noise
07:58 AM XXCoder: see circuit, its not very complex
07:59 AM XXCoder: its essentally just 2 NOT
07:59 AM XXCoder: 2 wires has 2 NOT each, so it takes in bit noisy signal and outputs clean
08:01 AM Tom_L: depends how fast the 1N5404 are
08:01 AM XXCoder: yeah dunno, not buying for now
08:01 AM archivist: diodes should be built into any driver you already have
08:03 AM XXCoder: hey I saw someone use a cap on tb6600 to smooth power intake
08:03 AM XXCoder: im not sure what rating it should be
08:04 AM Tom_L: the cap would need to be sized to the frequency of noise to work well
08:04 AM XXCoder: yeah? thought its to gloss over any dips
08:04 AM archivist: capacitors on power rails is the right thing to do
08:04 AM XXCoder: doubt it will happen, im using 2a when it can go 3a (my psu has enough power)
08:52 AM gonzo_: ping
09:02 AM jthornton: http://paste.ubuntu.com/24157919/ this is confusing
09:04 AM malcom2073: jthornton: You're missing the source package for libxenomai-dev
09:05 AM malcom2073: You have deb-src stuff in your apt list files?
09:05 AM Jymmm: jthornton: apt-cache show libxenomai-dev
09:09 AM jthornton: malcom2073: no, I'm missing deb-src stuff
09:10 AM jthornton: nevermind, I'm trying to build the wrong thing on this pc :(

12:07 PM CaptHindsight: describes SLA printing
12:08 PM CaptHindsight: and SLS for the barrel and receiver
12:11 PM gregcnc: is walmart selling cases of 40mm yet?
12:17 PM CaptHindsight: ms that it's ok as long as you use them to defend yourself and the 2nd amendment, the other amendments don't seem to matter
12:18 PM CaptHindsight: ms/seems
12:26 PM gregcnc: grenade launcher sounds menacing, but you have to have grenades otherwise a spud gun is probably more lethal than foam or powder 40mm
12:30 PM CaptHindsight: lead is not difficult to print
12:30 PM IchGucksLive: hi ;-)
12:31 PM CaptHindsight: they didn't say much about the composition of the grenades
12:32 PM CaptHindsight: researchers selected this particular round because it doesn't require any explosive propellants
12:32 PM SpeedEvil: It's a spring powered grenade launcher.
12:32 PM SpeedEvil: I suspect they mean explosives.
12:32 PM CaptHindsight: I don't see why it could not launch other rounds
12:34 PM CaptHindsight: what the article gets wrong is mass production
12:35 PM IchGucksLive: CaptHindsight: did you read the log
12:35 PM IchGucksLive: about the CHEES mill going on Hard stuff
12:36 PM IchGucksLive: as i said yesterday
12:36 PM Jymmm: CaptHindsight: The grenade is made of "chalk"... http://www.thefirearmblog.com/blog/2015/08/04/atf-rules-40mm-practice-chalk-rounds-are-explosives-destructive-devices/
12:36 PM CaptHindsight: it's still quicker to CNC the parts since much of the 3d printer tech is under patent
12:37 PM Jymmm: CaptHindsight: Since when does the gubermint comply with patents and trademarks?
12:37 PM CaptHindsight: IchGucksLive: I saw the video ~3;00, I didn't notice the problem
12:37 PM IchGucksLive: There is no even on that chunk mill
12:37 PM IchGucksLive: that is the goal
12:38 PM CaptHindsight: Jymmm: many of the parts will always be made faster by cutting vs additive
12:39 PM Jymmm: CaptHindsight: I was just commenting on the lack of "explosives" in the round
12:39 PM SpeedEvil: Or stampin
12:39 PM CaptHindsight: but I am waiting to see them at walmart
12:40 PM CaptHindsight: Jymmm: I understand, but the launcher can handle other grenades
12:40 PM Jymmm: CaptHindsight: glitter grenades?
12:40 PM CaptHindsight: you can't tell that the author doesn't understand the tech
12:43 PM CaptHindsight: http://asc.army.mil/web/news-alt-amj17-rambos-premiere/ better article
12:48 PM CaptHindsight: does anyone else get a asc.army.mil uses an invalid security certificate. at their https://asc.army.mil/web/
12:49 PM CaptHindsight: does the US Army website really have invalid certs?
12:50 PM t12_: i get it too
12:50 PM t12_ is now known as t12
12:51 PM CaptHindsight: hey t12
12:51 PM t12: Issuer: DOD ID SW CA-38, U.S. Government
12:52 PM roycroft: it's signed by an untrusted ca
12:52 PM t12: dod may have its own CAs
12:52 PM t12: that arent on the public lists
12:52 PM roycroft: which sounds right
12:52 PM roycroft: it's generally accepted that government cannot be trusted :)
12:53 PM CaptHindsight: hehe
12:53 PM t12: heya capt
12:55 PM CaptHindsight: any fun stuff going on out there?
12:55 PM t12: just lots of silly work
12:55 PM t12: characterized the shit out of cr2032s
12:56 PM t12: the obvious answer is: they vary drasticly by brand
12:56 PM t12: energizer wins
12:56 PM t12: mitsubishi second
12:56 PM CaptHindsight: t12: have you come across a large extruder for 3d printing? 3-5mm dia orifice, takes pellets vs filament sort of thing
12:56 PM t12: negative
12:56 PM t12: someone made a mig one
12:57 PM CaptHindsight: http://www.titan3drobotics.com/pellet-extrusion-3d-printing-on-the-atlas/
12:57 PM t12: why the vacuum
12:58 PM CaptHindsight: I think that is the feeder
12:58 PM CaptHindsight: the canister above is a filter
12:58 PM t12: the KF fittings and spiral hose to the right?
12:59 PM t12: maybe its just fume extraction and thats what was lying around
12:59 PM CaptHindsight: or you drop pellets in the canister/filter and the vacuum is for voc's as it heat the pellets
12:59 PM CaptHindsight: yeah
12:59 PM t12: and filter just for pump protection
01:00 PM CaptHindsight: things like PVC are best done without you breathing it
01:01 PM malcom2073: https://www.youtube.com/watch?v=SKtbBToSrv0
01:01 PM CaptHindsight: or thats what they had a Farm & Fleet for fittings and parts :)
01:01 PM malcom2073: That's kinda cool
01:01 PM t12: lol
01:01 PM t12: i cant think of a retail place i could purchase kf fittings
01:01 PM CaptHindsight: another thing I have to make vs just buy
01:02 PM CaptHindsight: t12: was thinking more of the filter on top
01:02 PM t12: old tshirt and a rubberbrand
01:02 PM t12: band
01:06 PM CaptHindsight: https://www.youtube.com/watch?v=MJl26VLsM9U Pellet 3d printer
01:07 PM t12: https://www.youtube.com/watch?v=1kZV587_42c&t=35s
01:07 PM t12: style points for the hole saw as hopper
01:10 PM CaptHindsight: are there any extruders for filament that have a large orifice?
01:14 PM CaptHindsight: http://www.e-ci.com/baam
01:21 PM CaptHindsight: http://www.rjmcompany.com/pipe-fusion-machines/plastic-extrusion-welder.htm
01:24 PM IchGucksLive: Gn8 im off
01:26 PM gregcnc: So how much tax would this robot have to pay under Gate's plan and would you still tip? https://youtu.be/oMREA_XLQ1A?t=23s
01:28 PM CaptHindsight: could be fun, choose from a selection of pre-approved styles, the Moe, the Moe or the Moe
01:47 PM CaptHindsight: t12: did they add milling to the mig "puting" head printer?
01:49 PM gregcnc: The comments in the liquid metal printer nail it. investment casting, duh print the mold
01:54 PM CaptHindsight: people often get stuck on trying to make their one tool do all
01:55 PM CaptHindsight: vs coming up with better tools to better fit the application
01:55 PM CaptHindsight: tough when your profit depends only only making one thing
01:57 PM CaptHindsight: much of the FDM/FFF noise has died down, now it will move into only the applications that it better fits
01:57 PM CaptHindsight: vs claiming to do everything
01:58 PM gregcnc: yeah as people realize where it fits
01:59 PM malcom2073: When you have a hammer, everything looks like a nail
01:59 PM CaptHindsight: the nail that sticks out most gets hit first
02:01 PM CaptHindsight: did I see a patent on FDM with a roller to press the extrusion onto the surface below?
02:02 PM CaptHindsight: https://markforged.com/products/ maybe it was these
02:03 PM CaptHindsight: I'm still waiting for one that is combined with weaving
02:30 PM Cromaglious_: wooo hoooo... getting even closer on PID speed control of spindle using PID of 2,.1,2 is working.. now to fix the wander.. I need to increase I of PID
02:30 PM ripple: malcom2073: "when you have a hammer...." quote that you wrote is actually quite profound. If im thinking about a project and I come to a wall while using a mill, I can walk to the lathe and think to myself "can I do this on the lathe?" Its just like a good way to think outside the box
02:31 PM Cromaglious_: now to figure out how to use hal to send via the usb port the spindle speed wanted...
02:31 PM ripple: Cromaglious_: you should get it all done, then do a video of your process for others using similar hardware =D
02:32 PM Cromaglious_: getting there...
02:32 PM Cromaglious_: RobiSydney on youtube is my video's
02:34 PM Cromaglious_: and weird thing... S12000 causing it to slow down... I have serial turned on to debug that
02:34 PM ripple: nice!
02:34 PM Cromaglious_: 5v == 0rpm 0v==12000 rpm
02:34 PM ripple: which controller?
02:37 PM Cromaglious_: it's a ebay BOB using it's 0-10v output to a resistor bridge to get the 0v to 5v and this pwm speed control http://www.ebay.com/itm/12V-24V-48V-12-50V-15A-600W-DC-Motor-Speed-Control-PWM-MACH3-USB-CNC-PLC-/181805146576?hash=item2a546e61d0:g:nOwAAOSwr7ZW3EJL in the middle is a Arduino Nano
02:37 PM Cromaglious_: if you google PID speed control ino you can find the file I started with
02:38 PM ripple: so, linuxcnc > potentiometer location of this lil heatsink thingy > motor?
02:39 PM Cromaglious_: Kp Ki Kd he has are totally wrong... start with 2,.1,2 0.15,0.01,.015 that he had really didn't work well
02:40 PM Cromaglious_: yep... the pot is wired across a 5v wiper gnd I go into the pwm port on the sideand move the jumpers
02:40 PM ripple: nice, you drive this with printer port?
02:41 PM Cromaglious_: parallel port BOB 1 relay one...
02:41 PM ripple: where does the usb port come into play?
02:42 PM Cromaglious_: http://www.ebay.com/itm/1PCS-5-Axis-Interface-CNC-Breakout-Board-For-Stepper-Driver-Controller-MACH3-New-/332142861683?hash=item4d5541dd73:g:Q8wAAOSwax5Yt-VU
02:43 PM Cromaglious_: usb port is required to power the nano and the BOB, though not nessisarely from a computer
02:44 PM Cromaglious_: If I can bypass the BOB and go directly into the Nano I can get better rpm selection control
02:45 PM Cromaglious_: DOH! in stepconf... I can have rpm 0 == pwm 1, and rpm 12000 == pwm 0.1
02:45 PM ripple: HAAAHAHHA
02:45 PM ripple: nub
02:45 PM Cromaglious_: crap then I have to wire the spindle power actually through the relay on the board
02:46 PM Cromaglious_: rpm 0 == pwm 0...
02:46 PM ripple: yesterday I was configuring joint0 and joint1 soft limits for XZ but X relys on both J0 and J1 so I was stopping Z from moving since I was poorly thinking about joint vs axis
02:47 PM Cromaglious_: non cartesian?
02:47 PM ripple: yeh
02:47 PM ripple: its a strange creature
02:47 PM Cromaglious_: I have a test polarsetup I need to play with hal about after I get PID speeed nailed down
02:47 PM ripple: polar?
02:48 PM Cromaglious_: using my 4th axis and a linear rail as an arm. so X,Y == Theta,r (angle and distance)
02:50 PM Cromaglious_: r== sqrt(x^2+y^2), theta in radians == atan2(x,y)
02:50 PM Cromaglious_: r== sqrt(x^2+y^2), theta in radians == atan2(x,y)== in degrees atan2(x,y)*180/pi of which 1 radian == ~57 degrees
02:51 PM ripple: so, linear rail with an actuated hinge?
02:54 PM Cromaglious_: pivot yeah...
02:54 PM Cromaglious_: ripple AvE just did 2 video's on it last week
02:57 PM Cromaglious_: it you keep it in the upper right quadrant math is easy... moving the pivot to maxXofRaile,MaxYofRail give you a bigger area with positive X and Y to play with.. with the hold in the middle where arm can get the tool within like 60mm on the pivot point (120-200mm) diameter dead spot
02:57 PM ripple: I reealy need to learn more about kins im so out of touch with it
02:57 PM ripple: however that is a lesson for another day
02:58 PM ripple: I must get back to the shop
02:58 PM ripple: bah I need 3phase at home
02:58 PM Cromaglious_: I understand the math... trying to understand how to set it up in HAL
02:59 PM Jymmm: ripple: get peddling... http://i168.photobucket.com/albums/u200/Vankoff/Setup.jpg
02:59 PM Cromaglious_: ripple get a 3ph converter rated motor... either start it with a capacitor 3ph setup or just spin it with another motor.. onceit's running you have you 3rd phase
03:00 PM CaptHindsight: http://www.ebay.com/itm/220V-Handheld-Plastic-Extrusion-Welding-Machine-Extruder-Welder-Gun-Booster-EX2-/152389161278
03:01 PM CaptHindsight: wonder if they just use an auger bit for wood as the extruder screw
03:02 PM Cromaglious_: CaptHindsight, one way of doing it...
03:03 PM CaptHindsight: or if they use a screw designed for a small diameter short barrel
03:08 PM Cromaglious_: finally got working udev rules on all machines
03:31 PM gregcnc: Cromaglius what is your polar machine machine ?
03:47 PM rene-dev: pcw_mesa Hi, occasionally I get a remote fault with my smart serial slave implementation. what exactly causes that?
04:07 PM Deejay: gn8
04:10 PM Cromaglious_: got hall effect x home switch mounted.. now to figeur out pin assignment
04:35 PM Crom: bbl
04:43 PM MacGalempsy: good afternoon
04:44 PM MacGalempsy: just found your next monitor https://flic.kr/p/SChyzU
04:44 PM Tom_L: hi
04:45 PM MacGalempsy: only $5! even still has the bullet lodged in it!
04:46 PM MacGalempsy: lol. that was at a local indoor flea market
04:46 PM Tom_L: somebody will buy it
04:47 PM MacGalempsy: i like the mark down sales gemmick
04:48 PM Tom_L: you know you wanted to take it home...
05:07 PM MacGalempsy: kinda!
05:07 PM MacGalempsy: just for a christmas present or something
05:08 PM XXCoder: mac thats good for grabbing guts to fix other montior
05:08 PM XXCoder: or some other use
05:09 PM gregcnc: isn't the pcb right behind the lcd?
05:09 PM XXCoder: nope
05:09 PM XXCoder: maybe maybe not
05:09 PM XXCoder: maybe it missed, but as sign says its working
05:10 PM XXCoder: it might tag a led light source or something but rest of it is functional
05:10 PM gregcnc: after you turn over the 5$ it's your maybe working "moniter"
05:10 PM XXCoder: yeah I wouldnt bother, can buy better but same price at used stuff stores
05:10 PM XXCoder: like at salivation army
05:11 PM XXCoder: cant spell that word
05:11 PM gregcnc: my samsung was getting flaky with the backlighting, but then it just stopped one day and has been fine for over a year
05:11 PM gregcnc: I found a big write up on changing caps and such
05:12 PM XXCoder: caps is typical death of electrics
05:13 PM gregcnc: i don't remember the details but it was fairly common for the 245
05:13 PM XXCoder: my old montior (still have it) have dead backlight
05:13 PM XXCoder: its cold cathode type not led, its old
05:14 PM gregcnc: this one is not LED either I was contemplating replacing both 24's but they live
05:15 PM XXCoder: I dont know enough about electrics to check it over
05:36 PM Cromaglious_: there was a period of time in the early 2000's that things died early because of capacitor plague
05:37 PM XXCoder: my montior is 2000s
05:37 PM XXCoder: early even
05:37 PM Cromaglious_: none of my gear from 2002 to 2006 has survived...
05:37 PM XXCoder: it lived for long time, but died 2 years ago
05:37 PM Cromaglious_: earlier and latertypically has survived
05:37 PM XXCoder: I guess I got lucky
05:38 PM Cromaglious_: There was one factory that produced like 90% of this certain part for capacitors... and it burned down
05:40 PM Cromaglious_: https://en.wikipedia.org/wiki/Capacitor_plague
05:43 PM Cromaglious_: fsckers I was lied too... they just made them wrong
05:44 PM XXCoder: reading
05:44 PM gregcnc: Cromaglius what is that polar coordinate machine you're working on?
05:45 PM XXCoder: dell paid 420 million
05:46 PM XXCoder: interesting thanks
05:50 PM Cromaglious_: working on a way for linuxcnc to have a drop in polar conversionfor basically a 4th axis on it's side with a linear rail on top of it, with a plasma torch at the end
05:53 PM Cromaglious_: There is also the slant bed router, which has a winch at each corner and HAL would determine how much cable would have to be out of each winch for any give x/y
05:57 PM Cromaglious_: that math is a bit tougher... since you have a triangle with one known side (distance winches are apart) then figuring out what the other 2 sides are. which can be broken in 2 right angle triangles. Winch 1 is considered at -20,-20 and winch 2 is considered to be 1500,-20 and then you can solver for anything from x0y0 to x1480,ynumberthat's prettydamnbig
05:58 PM XXCoder: so cnc router that have bed can slant?
05:59 PM Cromaglious_: the bed is slanted... cut the router is hanging by gravity
05:59 PM Cromaglious_: s/cut/cuz/
05:59 PM XXCoder: interesting setup
06:01 PM Cromaglious_: around 80 to 60 degrees I'd think...around 65 degrees would be about optimal I would think... enough slant for the z to have some cutting pressure and verticle enough for X&Y to really have no drag
06:02 PM Cromaglious_: There's a guy doing on basically using a GRBL to control everything... like I said the math isn't that hard
06:06 PM Cromaglious_: take X/Y process for Theta and r or hypotenuse on your triangles for cable length where triangle 1 is ptA0,Ptb0-x,ptc0-xy cable length 1 is ptA to ptC length. triangle 2 is Ptbx,0-ptcXY-ptaWInchXY position cable 2 length is ptA to Ptc again
06:07 PM Cromaglious_: or hypotenuse of the right triangle where angleB (ptb) is 90 degrees
06:07 PM Cromaglious_: A1 B1B2 A2
06:08 PM Cromaglious_: C1 C2
06:08 PM Cromaglious_: C1C2
06:08 PM Cromaglious_: A1 B1B2 A2
06:08 PM Cromaglious_: C1C2
06:08 PM Cromaglious_: there that'smore like it
06:09 PM Cromaglious_: winch cable 1 is the a1b1c1 triangle andwinch cable 2 is a2b2c2 triangle and corner b is the right angle
06:14 PM Cromaglious_: you could probably run it completely vertical with some vacuum pads to keep the carriage in place. fun part is you can make it stick using vacuum and then use the air you suck in to make some air bearings to space it off the material. higher you get suck more, lower you go blow more.
06:17 PM XXCoder: so whats use for such machine? besides olvious "make parts"
06:20 PM Cromaglious_: almost 0 space foot print.5'x9' table would be like 4' wide, 8' tall, 10' long
06:21 PM Cromaglious_: and the back of the machine can be made a stock storage...
06:22 PM Cromaglious_: with the push me pull you vacuum/air bearing you could make is vertical for a 1' wide 7' tall 10' long
06:22 PM XXCoder: 10' long?
06:23 PM Cromaglious_: it's need to be longer and wider than the cut foot print
06:24 PM Cromaglious_: you'd never cut x0 y1500 with winch 1 at x0,y0, x would have to be like -50 and Y at -50 (X0Y0 is top left of the machine)
06:25 PM XXCoder: yeah but that dont sound like zero footprint, though I may be mis-visualizing
06:25 PM Cromaglious_: maybe even x-150 to get to y1500
06:25 PM Cromaglious_: think book case along the wall...
06:25 PM Cromaglious_: hell you could build it into the wall
06:27 PM Cromaglious_: 10' of open wall... you have rolling cabinets you can roll in front of it when you are not using it...
06:27 PM XXCoder: so 10' is along wall, and I guess 8' is ip and down
06:27 PM XXCoder: that leave it with 4'
06:28 PM Cromaglious_: cut area could be like 1' from each end and 1' down from the top to within 1' of the floor
06:29 PM Cromaglious_: you could have the work table be 4' tall and 8' along the wall and have the winches 2' above and to the outside of each corner
06:29 PM Cromaglious_: 4' tall and 1' off the floor
06:31 PM XXCoder: interesting
06:31 PM XXCoder: so its a way to have large cnc router without the footporint when its not used
06:32 PM Cromaglious_: think 12' bedroom wall. winch up in each corner up 8' so x/y in feet x0y0 winch1 (w1) x144y0 w2, is the middle of the wall
06:32 PM Cromaglious_: yep
06:32 PM XXCoder: nice
06:33 PM Cromaglious_: you could build a table, when you use it you pull the bottom out so you get your 65 degree angle cut cut cut, when done you drop it back flat against the wall
06:34 PM Cromaglious_: make it a bit smaller... have it over a twin bed... pull out the bottom, use it... when down back against the wall
06:35 PM Cromaglious_: s/down/done/
06:35 PM Cromaglious_: winches can be in the table... just use pulleys up at the corners
06:38 PM Cromaglious_: which would make it even easier... you can have long drums on the winch so you can use 1 layer if the pulley is far away.../\
06:38 PM Cromaglious_: gotta go...
06:39 PM XXCoder: later and thanks
06:40 PM XXCoder: https://www.youtube.com/watch?v=3b6ucEsyOv8 aww
06:41 PM JT-Shop: or just have a XY and move the sheet for X
06:42 PM XXCoder: theres router like that I saw on youtube
06:42 PM XXCoder: it has theorically infinite length on x
06:42 PM XXCoder: width is 9 foot
06:46 PM XXCoder: I find it interesting that horses have different play
06:47 PM XXCoder: one part where its at same site for 2 horses, one kicks it around and one carries it in mouth
06:48 PM XXCoder: white powder surface horse room weird
06:48 PM JT-Shop: cats can be very different too
06:49 PM Cromaglious_: http://www.maslowcnc.com/
06:49 PM JT-Shop: we had one cat Mickey short for Michelob that would play with a rubber band and toss it up in the air and catch it
06:51 PM XXCoder: oh yeah forgot about that crom
06:52 PM Cromaglious_: oh yeah chains
06:52 PM XXCoder: anyway one im talking about is pretty simple
06:52 PM XXCoder: invert the gantry, make it move it along X by rolls
06:52 PM Cromaglious_: heck you could use GT2 or GT3 belts
06:52 PM XXCoder: Y is setup same way as usual
06:52 PM XXCoder: so it moves stock
07:03 PM Cromaglious_: even easier... git clone https://github.com/MaslowCNC/Firmware.git
07:04 PM Cromaglious_: Kinematics already done!
07:09 PM JT-Shop: yea material is all sized up for tomorrows machining
07:15 PM Cromaglious_: they are using a Mega 2560
07:17 PM XXCoder: one of kickstarter I supported, miit, just failed
07:17 PM XXCoder: diappointing.
07:19 PM gregcnc: that induction cup kettle thing?
07:19 PM XXCoder: yeah
07:19 PM gregcnc: what went wrong?
07:19 PM XXCoder: they lost comapny that would make them stuff, and trying to find another failed
07:20 PM XXCoder: lemme get detailed
07:20 PM gregcnc: no need
07:20 PM XXCoder: https://www.kickstarter.com/projects/747044530/miito-the-sustainable-alternative-to-the-electric/posts/1828011
07:20 PM XXCoder: in least it clearly isnt scam like that flashlight I supported while ago
07:21 PM XXCoder: and I will get some money back, which is more than I expected
07:22 PM gregcnc: two years ago? are there no copies on alibuybuy or whatever yet?
07:22 PM XXCoder: none
07:22 PM gregcnc: no reason to build an overprice water heater
07:22 PM XXCoder: I wanted to just place cup put that disk thingy in
07:23 PM XXCoder: heat be done
07:23 PM XXCoder: mine was more advanced temperate control one
07:24 PM gregcnc: i bought a induction cooker with broken glass cheap to play with. It heated a 5Lb sledge hammer fairly quickly
07:25 PM XXCoder: cool
07:26 PM XXCoder: maybe you can design and market one
07:26 PM XXCoder: make sure it can tell what temperate water is
07:26 PM gregcnc: how did it measure water temp?
07:27 PM XXCoder: I think the disk thing has sensor that it send info back to base
07:27 PM XXCoder: its induction powered so plenty of power.,
07:28 PM JT-Shop: goodnight
07:29 PM gregcnc: www.ebay.com/itm/162234009675 with a flat coil
07:29 PM XXCoder: night jt
07:33 PM XXCoder: man some kickstarters is olviously already finished product
08:03 PM enleth_ is now known as enleth
08:32 PM CaptHindsight: XXCoder: I guess an EE isn't was it used to be
09:34 PM chopper79: I just blew up my laser tube in my desktop laser cutter/engraver.
09:35 PM chopper79: Now I need to decide what I will turn this carcass of a laser cutter into...
09:39 PM jdh: get a 100w replacement tube/ps
09:39 PM chopper79: Not sure if it even worth it....
09:40 PM Wolf_: new 50w tube is cheap
09:40 PM chopper79: Little cheap K40 laser. Replacment tube is $165.00
09:43 PM chopper79: Whole laser new is only $350 so spending 235.00 on a 50w tube and an additional 200 on PS seems like a poor investment. Not the origanal purchase was a good investment.
09:44 PM Wolf_: https://www.aliexpress.com/item/Best-Quality-700MM-40W-Co2-Laser-Tube-for-Engraver-Cutting-Machine-Water-Pipe-Kafuter-Silicone-Rubber/32460451752.html
09:45 PM chopper79: chances of that making it to me in one piece from China is very low.
09:45 PM chopper79: Been there done that
09:46 PM Wolf_: 100w tube is more fun, $520 for the tube, $400+ for shipping
09:46 PM chopper79: Maybe I should turn the machine into a pcb mill and use a smoothie to run it.
10:06 PM BubbleRe- is now known as BubbleRep
10:06 PM tumdedum_ is now known as tumdedum
10:20 PM XXCoder: Wolf_: nice
10:20 PM XXCoder: 125 bucks shipped not bad
10:20 PM Wolf_: thats a small tube
10:21 PM XXCoder: I ordered a lot of 2020 extrusions heh 4 or 550mm, 4 of 400mm and 4 of 200mm
10:21 PM XXCoder: its to make a machine parts box
10:21 PM XXCoder: chopper79: cheap fun is just buy laser diode, 1w or so. enough to have fun with now useless laser box
10:22 PM XXCoder: wolf its for pwm board, BOB tb6600s, and psus
10:22 PM XXCoder: should be plenty of room.
10:23 PM Wolf_: https://www.aliexpress.com/item/2-5w-high-power-450NM-focusing-blue-laser-module-laser-engraving-and-cutting-TTL-module-2500mw/32790785641.html
10:23 PM XXCoder: yeah something like that
10:23 PM Wolf_: there ya go, diode laser :)
10:24 PM XXCoder: though there should be cheaper ones
10:24 PM XXCoder: I wonder how easy it is to make laser crystal engraver
10:24 PM Wolf_: nope, i looked
10:25 PM Wolf_: 2.5w tho
10:25 PM XXCoder: from what I see, need laser and reference laser
10:25 PM XXCoder: whats weird is that theres 2w laser pointers

10:32 PM Wolf_: probably has a 0.5% duty cycle to keep it from burning up
10:32 PM XXCoder: hmm true forgot about duty cycle
10:42 PM XXCoder: wow tritium is half off

10:46 PM XXCoder: laser diode 2000mw/2w = 0 ;)
10:47 PM XXCoder: wow this laser must be so powerful it shatters glass from nowhere. https://www.aliexpress.com/item/2000mw-High-Powered-Burning-Blue-Laser-Pointers-2W-Lazer-for-sale-with-2-18650-Battery-Charger/32746258804.html
10:49 PM Crom_on_phone: Maslow hanging cnc is looking better and better
10:49 PM XXCoder: wb
10:50 PM Crom_on_phone: Not back yet... Wont be home for at least another hoir
10:50 PM XXCoder: no, talking about this channel :P
10:50 PM Crom_on_phone: Though being able to irc from the phone rocks!
10:51 PM Crom_on_phone: What was the data service way back when.... They put tranceiver on the power poles....
10:52 PM Crom_on_phone: 93.... Saw it live at Linuxcon in San Jose back then
10:53 PM Crom_on_phone: Wish i had the bt keyboard with me
10:54 PM Crom_on_phone: Well motors, chain, sprockets for maslow is $80ish
10:55 PM chopper79: XXCoder: Yeah it is a useless box so I have to do something with it. I have a 1.5w uv laser I may put on it. Still not sure if I even want to do anything at all with it.
10:55 PM Crom_on_phone: Everything else i think i have... H bridge, mega, wood, 12vdc ps
10:55 PM XXCoder: yeah turn fancy laser thingy into cheap laser engraver thing
10:56 PM Crom_on_phone: What will 1.5w uv do?
10:57 PM Crom_on_phone: Cure glue.... Erase eprom...
10:57 PM Crom_on_phone: I think it'll mark paper
10:58 PM chopper79: engrave
10:58 PM chopper79: cut paper
10:58 PM chopper79: so pointless
10:58 PM XXCoder: you can make cardpaper statues
10:58 PM chopper79: lol
10:58 PM Crom_on_phone: Heh... Make encoder disks then
10:58 PM XXCoder: I remember there was that type of slicer but cant find it now
10:59 PM XXCoder: even can define spacings
11:00 PM chopper79: Find me a 200w fiber laser and then I can use the machien to do SLS
11:00 PM Crom_on_phone: I need to makr some my self... So i have to set up the bucket, and all the other crap for the 40w co2 laser
11:00 PM chopper79: 3D printed aluminum parts
11:02 PM Crom_on_phone: Don't spill Tannerite on there
11:03 PM chopper79: Why not I will just be explosive hardeing my parts so its a benefit right?
11:04 PM Crom_on_phone: Sintering powdered metal setup would be really nice
11:04 PM chopper79: I agree
11:04 PM chopper79: print it off and then qualify the parts and suraces in a mill.
11:04 PM Crom_on_phone: What was the one that sprayed glue on a powder
11:05 PM chopper79: Could make shapes that could not be made otherwise.
11:05 PM Crom_on_phone: Then they'd stick it in an oven inflow pewter into it
11:06 PM Crom_on_phone: I think the powder was some sort of bronze
11:06 PM chopper79: dont remeber what it is called but yeah they use a binder that is sprayed on like an ink jet printer then bake it with bronze powder in it.
11:06 PM chopper79: Was cool but took for ever.
11:07 PM Crom_on_phone: They are using a commercially to make kitchen cabinet knobs
11:07 PM chopper79: https://www.youtube.com/watch?v=i6Px6RSL9Ac
11:07 PM Crom_on_phone: Well I'm not at home so I got to watch that when I get back
11:08 PM Crom_on_phone: I think there is a How It's Made episode on that
11:08 PM chopper79: I think that is the link I posted..haha
11:09 PM Crom_on_phone: I'm looking at these motors with these and coders on the back thinking hey can I use them instead of steppers it's like 12 bucks for a motor with encoder with a 6 millimeter output shaft with the flat spot already on it
11:09 PM chopper79: nice
11:10 PM XXCoder: I so want SLS
11:10 PM Crom_on_phone: Encoder.. Google voice typing sucks
11:10 PM chopper79: Same here XXCoder
11:10 PM Crom_on_phone: Ditto!
11:10 PM XXCoder: too bad theres no cheap SLS
11:10 PM chopper79: 100K and up
11:11 PM Crom_on_phone: Print a 1911a1 frame.... Then flow bronze into it
11:11 PM XXCoder: theres 1,000 ones but still not cheap
11:11 PM chopper79: really?
11:11 PM XXCoder: that video having hmm 8 lasers? seems cool
11:11 PM chopper79: who makes those
11:11 PM XXCoder: I may have misrememebred with sla not sls but let me check
11:11 PM Crom_on_phone: Yeah its SLA
11:12 PM XXCoder: https://3dprint.com/60563/you-sls-printer-for-2000/
11:12 PM XXCoder: 2k
11:12 PM chopper79: SLA is much cheaper and still cool.... but not lasers melting metal and building shit cool
11:12 PM Crom_on_phone: woooo
11:13 PM XXCoder: domain for sale :(
11:13 PM chopper79: booo
11:14 PM XXCoder: http://www.instructables.com/id/You-SLS-DIY-Laser-sintering/
11:14 PM chopper79: Sweet... I book marked it.
11:14 PM chopper79: Thanks
11:14 PM XXCoder: np
11:15 PM XXCoder: it dont seem to complete design either
11:15 PM XXCoder: but it has more overall view
11:15 PM Crom_on_phone: Yeah the powder depositor sections going to be the hard bit
11:16 PM Crom_on_phone: .2mm thick layer you think?
11:16 PM XXCoder: probably
11:16 PM XXCoder: can less I bet, it depends on how thinkly it can lay down powder
11:18 PM chopper79: Maybe one day
11:18 PM Crom_on_phone: Sinter nylon, then i guess plaster over it, bake out nylon, then pour into a vacuum chambered mold?
11:18 PM XXCoder: that video it seem to be bounded metal powder, just bake it and it reflows properly
11:18 PM XXCoder: I dont know what you-sls could do
11:18 PM Crom_on_phone: Shows over back to work
11:19 PM chopper79: later
11:19 PM XXCoder: have fun
11:19 PM chopper79: XXCoder: I do not understand your question
11:19 PM XXCoder: which question?
11:19 PM chopper79: (10:49:23 PM) XXCoder: I dont know what you-sls could do
11:20 PM Crom_on_phone: Gonna load out lights, costumes, props
11:20 PM XXCoder: what its cabilities are and so on
11:20 PM XXCoder: can it do metal powder? or just plastic powder? so on
11:20 PM chopper79: metal
11:20 PM Crom_on_phone: Depends on system
11:20 PM chopper79: I will link a nice video I have been watching the epast few days.
11:20 PM Crom_on_phone: The german kid was saying nylin
11:21 PM Wolf_: sls is kinda ok, spacex makes rocket nozzles with it
11:21 PM Crom_on_phone: Sls anything is good if you can bake it out of a plaster mold
11:22 PM chopper79: https://www.youtube.com/watch?v=gqKYKRDQNac
11:22 PM XXCoder: new clickspring video!
11:22 PM chopper79: The parts coming off this machine are crazy awesome. Printed inconel
11:22 PM XXCoder: printed inocel??
11:22 PM chopper79: yes
11:23 PM Wolf_: yup :)
11:23 PM chopper79: watch the video you can run steel, alum, inconel, titainum, etc.
11:23 PM XXCoder: will look as soon as clickspring video isn done
11:23 PM chopper79: Even show completed parts at the end. nice but I am sure very exspensive.
11:25 PM chopper79: Talked about printing full engine blocks and stuff
11:26 PM chopper79: about the 5:30min mark is where they get into the big stuff
11:30 PM XXCoder: https://www.youtube.com/watch?v=Jk_rCm1rAeg
11:30 PM XXCoder: wow indeed
11:31 PM XXCoder: watching now
11:36 PM cncnoob: Hey guys, any idea why my tool table offsets would be changing? I only enter the Z offset, but when I restart Axis the value is different from the value I entered
11:38 PM XXCoder: chopper79: dang the inocel parts is complex
11:38 PM XXCoder: imange the milling time!
11:38 PM chopper79: And that is why I want one....haha
11:38 PM chopper79: AWESOME!!
11:39 PM chopper79: cncnoob: Not sure on that one. Are you using lets say a G56 coordinate and then when you restart it is defaulting to g54
11:40 PM chopper79: I seen that once on mine and then when I switch to g56 the offsets were correct.
11:40 PM XXCoder: amazing video.
11:41 PM XXCoder: https://3dprint.com/12944/sintratec-sls-3d-printer-cheap/
11:41 PM cncnoob: @chopper79, I have never used g56 to my knowledg
11:41 PM chopper79: It was just a thought.
11:42 PM cncnoob: At least it isn't in any of my programs and I haven't keyed it in :)
11:43 PM cncnoob: I read that tool tables pre linuxcnc v2.4 could be updated automatically, but I've only used 2.7.8 so I wouldn't think that would be the cause.
11:44 PM chopper79: Should update tool table when you set the offset and then when you shut axis down and restart it should read the tool table and be good to go.
11:44 PM chopper79: Not sure why your would not be
11:46 PM Crom_on_phone: To use a gtx offset you'd have to have tooling that repeatable
11:46 PM Crom_on_phone: G5x
11:47 PM Crom_on_phone: With my er11 not happening
11:47 PM XXCoder: its easy enough, set a spot to touchoff tool and set Z each time
11:47 PM XXCoder: thats why I dont bother with tool lengths
11:48 PM Crom_on_phone: X y loose too many steps.... Gotta rehome every time every
11:49 PM XXCoder: odd issue there. my old tb6560 had that but tb6600 it dont seem to happen
11:49 PM cncnoob: I set up my post to change to T99 at the end of every program
11:49 PM cncnoob: That is my edge finder
11:49 PM cncnoob: I put an offset in the tool table for it as well
11:50 PM cncnoob: So ever time I mount a work piece I touch off x, y, and y with the edge finder
11:50 PM cncnoob: then when I run my program it asks me to manually insert the first tool required by my program
11:50 PM chopper79: So the tool table is not keeping the offset for the edge finder?
11:50 PM Crom_on_phone: I think using G38 it possible to do a home of sorts
11:50 PM cncnoob: before I even started the program I made sure the tools used by my program were in the tool table
11:51 PM chopper79: Ok, but the offsets changed right?
11:51 PM XXCoder: for me I just jog to near as I can go safely then I turn steppers off and manually move it to home
11:51 PM cncnoob: but after i manually insert the tool like the program requested the offset is incorrect
11:51 PM XXCoder: turn steppers on and set home
11:51 PM XXCoder: donme
11:51 PM XXCoder: pretty repeatable.
11:51 PM chopper79: cncnoob: you using tool holders?
11:52 PM cncnoob: just had a thought, maybe camworks is doing some compensation that I'm not intending it to use
11:52 PM cncnoob: yes
11:52 PM cncnoob: R8
11:52 PM chopper79: TTS?
11:52 PM cncnoob: I don't know what TTS is
11:52 PM Crom_on_phone: Tts rocks
11:52 PM chopper79: tormach tooling system
11:52 PM Crom_on_phone: Tormach tool system
11:53 PM chopper79: or are you using r8 that are tool holders and not r8 collets
11:53 PM cncnoob: Not yet!
11:53 PM cncnoob: I do what to do that though
11:53 PM cncnoob: I converted my HF mini mill to CNC
11:53 PM Crom_on_phone: Using a ground face 3/4" r8 collet
11:53 PM cncnoob: that is the first upgrade I want to make
11:53 PM cncnoob: power draw bar with TTS
11:53 PM chopper79: so right now you are using a r8 endmill holder let say?
11:54 PM cncnoob: yes
11:54 PM chopper79: ok then you shoudl be able to repeat the tool offset fine.
11:54 PM Crom_on_phone: Yeah tormachs use of the spring washers is a great 💡
11:55 PM chopper79: So that eliminates the tool length changing in the collet, since your using and endmill holder.
11:55 PM chopper79: How far is the offsets changed by?
11:55 PM Crom_on_phone: They use 3 air cylinders staged on top of each other to get the push required
11:55 PM cncnoob: it is considerable, but I haven't measured
11:56 PM cncnoob: I'll pay close attention tomorrow when I start it back up to see if it is doing something dumb like doubling the offset
11:56 PM cncnoob: I guess I just wasn't expecting LinuxCNC to change it at all after I had set it
11:56 PM cncnoob: that is what is confusing to me
11:56 PM chopper79: Only thing I can think of is your puttin gin lets say tool 2 inplace of tool 1.
11:56 PM cncnoob: why is it changing it...
11:56 PM chopper79: It shoul dnot change
11:56 PM cncnoob: hummm
11:56 PM cncnoob: I don't think I'm doing that
11:57 PM chopper79: It will only change if you inout new values .
11:57 PM cncnoob: I only have 3 tools in my table till I get it worked out
11:57 PM cncnoob: tool 1, 26, and 99
11:57 PM cncnoob: 1 and 26 are tools that I have in CAMWorks
11:57 PM cncnoob: 99 is my edge finder
11:57 PM chopper79: so no chance that your puting in tool o1 when you are needing tool 26?
11:57 PM chopper79: I have done that before
11:57 PM cncnoob: Nope
11:58 PM cncnoob: one is a 3/4" end mill and the other is a 0.0197" end mill
11:58 PM cncnoob: hard to get confused :)
11:58 PM chopper79: In your config you do not 2 tool table files in there by accident do you?
11:58 PM chopper79: done that myself also
11:58 PM Crom_on_phone: If you grind the face of you quill you'll get better homing
11:58 PM cncnoob: there is a backup file which I didn't create
11:59 PM chopper79: delete the back up file
11:59 PM cncnoob: Will do
11:59 PM Crom_on_phone: If your face isnt ground you could get different lengths
11:59 PM chopper79: I ran into an issue where I had to delete the back up file nd the var file.
