12:01 AM LeelooMinai: Er, not sure if I have halucinations, but are those links in news section doing something strange with the font? http://app2.kitchener.ca/digital/
12:04 AM LeelooMinai: Maybe it's my glasses
12:04 AM LeelooMinai: Or one of those optical illusions
12:04 AM XXCoder: its annoying light blue on white color, besoides that seems ok
12:04 AM XXCoder: oh maybe its script based'
12:04 AM LeelooMinai: No, I mean they shape-shift on me:(
12:04 AM XXCoder: script enabled, no difference
12:05 AM LeelooMinai: Figured it out - it's my glasses - when I look at side monitor and then back to the center one, there's shift in colors it seems and the font changes width.
12:05 AM LeelooMinai: Or rather thickness - looks more bold.
12:10 AM LeelooMinai: E, no Twitter - just YouTube mostly
12:10 AM XXCoder: lol ok
12:13 AM LeelooMinai: Hmm, apparently there's something called pimatic - home automation for RPI. Looks interesting and I have TP-HS110 smart plug thingy with power metering that is supported.
12:15 AM LeelooMinai: I wish RPI 3 was a bit cheaper.
12:25 AM SpeedEvil: orange pi
12:26 AM LeelooMinai: No orange - reminds me of someone too much
12:27 AM XXCoder: lol
12:27 AM XXCoder: hes been not orange for while now
12:27 AM XXCoder: guess he finally listened to his advisors
12:28 AM LeelooMinai: I doubt he listenes to anyone.
12:28 AM LeelooMinai: Only voices in his head probably.
01:09 AM XXCoder: LeelooMinai: https://www.youtube.com/watch?v=feNyf6JHzNA
01:09 AM XXCoder: thats machine im been running for couple months now
01:09 AM XXCoder: its so annoying
01:09 AM LeelooMinai: At home?
01:10 AM XXCoder: nah at work
01:10 AM XXCoder: it keeps breaking down
01:10 AM XXCoder: that dang thing looks so shiny
01:10 AM LeelooMinai: Seems pretty tiny. Is it expensive?
01:11 AM XXCoder: at 1:50 it shows that evil chips drawer
01:15 AM pink_vampire: XXCoder: why it is braking down?
01:15 AM XXCoder: due to all the abuse
01:16 AM XXCoder: its not a production machine
01:16 AM pink_vampire: it's look like the cm-1
01:17 AM pink_vampire: i want it!!
01:18 AM XXCoder: its great for protyping yeah. $50,000 new I think lol
01:18 AM LeelooMinai: pff
01:18 AM LeelooMinai: I think Tormach would make more sense
01:19 AM XXCoder: probably yeah. much cheaper also.
01:19 AM LeelooMinai: Haas is US company?
01:19 AM pink_vampire: rails on the haas much much much better
01:19 AM pink_vampire: yes
01:20 AM pink_vampire: I *want* the haas
01:20 AM pink_vampire: but purchasing is not part of the fantasy
01:20 AM XXCoder: too bad :)
01:20 AM pink_vampire: i just want it.
01:29 AM pink_vampire: if you want to feel normal http://imgur.com/gallery/ekUP9
01:30 AM XXCoder: geez. lol
01:30 AM pink_vampire: http://imgur.com/gallery/09a4O
01:31 AM pink_vampire: i need that.
01:31 AM XXCoder: yah saw that
01:31 AM XXCoder: pretty cool allright lol
01:41 AM pink_vampire: https://www.youtube.com/watch?v=TXvrfDqYI3s&t=311s
01:41 AM pink_vampire: jump to the start
01:42 AM pink_vampire: XXCoder:
01:42 AM XXCoder: looking
01:44 AM Wolf_: thats kinda cool
01:44 AM pink_vampire: https://www.youtube.com/watch?v=Yi-YXHsrbfA
01:45 AM pink_vampire: version 2
01:46 AM XXCoder: interesting
01:50 AM pink_vampire: it is funny that he say that name 17 take significant current
01:53 AM XXCoder: nema17? dunno lol
01:53 AM Wolf_: it does for those piece of shit china clone stepper drivers
01:53 AM pink_vampire: it use smt drivers
01:53 AM Wolf_: no heat sinking on them, crap components
01:57 AM pink_vampire: how the turret get locked on normal lathe?
01:57 AM Wolf_: dunno, I haven’t played with a cnc lathe yet, was messing with a haas last week
01:57 AM Wolf_: VMC
01:57 AM XXCoder: I ran lathe maybe 5 times? none of em was setup just insert part, hit button, remove part, clean and repeat
01:57 AM XXCoder: its been nearly a year since I last ran one actually. wow.
01:57 AM Wolf_: probably servo drive w/ hydraulic lock
01:57 AM pink_vampire: i did only few parts on the g0704 and the hf lathe that i had..
01:58 AM XXCoder: Wolf_: the gauge display for hydraulic stuff says yes.
01:59 AM Wolf_: just makes sense to use hydro because its also used for the the closer and brake system as well
02:01 AM XXCoder: yeah part place and removal uses foot pedal
02:01 AM XXCoder: it clamps till it reaches certain pressure set
02:01 AM XXCoder: thats why it has a gauge
02:01 AM * Wolf_ knows things
02:02 AM Wolf_: sorta...
02:02 AM Wolf_: really good at guessing as well
02:02 AM Wolf_: I need to find a new lathe for my shop =/
02:02 AM pink_vampire: https://www.youtube.com/watch?v=4fx-vEt88i0
02:02 AM Wolf_: and i need to spin some shit in my little HF pos
02:03 AM XXCoder: pink, considering getting a lathe?
02:03 AM pink_vampire: no.. i want laser cutter
02:04 AM XXCoder: ah was wondering on lathe links heh
02:04 AM XXCoder: laser isnt so easy :( blue box chinese you'd have to fix once it arrives because 110% chance its crappily made
02:04 AM XXCoder: or much more expensive non-chinese one
02:04 AM Wolf_: my laser cutter is half way done, least theory and mockup w/ 2.5w diode
02:04 AM pink_vampire: no no no
02:05 AM pink_vampire: i want something good
02:05 AM Wolf_: how big you planning pink?
02:05 AM pink_vampire: A3
02:05 AM Wolf_: thats all? what wattage?
02:06 AM pink_vampire: highest i can get
02:06 AM XXCoder: something like this? https://www.youtube.com/watch?v=I5elJpaq2qo
02:06 AM Wolf_: I’m planning a 4’ wide (1.5m x 1m) 100w co2
02:06 AM pink_vampire: XXCoder: NONONONO
02:07 AM XXCoder: this one I want https://www.youtube.com/watch?v=xBUBUlOYRrc
02:07 AM Wolf_: those are kinda neat
02:08 AM Wolf_: but, I want something that can cut wood efficiently
02:08 AM XXCoder: yeah the 5v ones wouldnt do that
02:08 AM XXCoder: so co2 is cheaper options
02:08 AM pink_vampire: around 150W-200W you can cut sheet metal.
02:08 AM Wolf_: yeah, cheap… like $4k for the tube and psu
02:09 AM Wolf_: for 100w
02:10 AM Wolf_: for most of the sheet metal I would be cutting I would need way more then 200w...
02:10 AM XXCoder: $1000 if chinese special blue box
02:10 AM XXCoder: you'd need to repair it
02:10 AM Wolf_: thats only 30w
02:10 AM XXCoder: dtill, wuite bit cheaper.
02:11 AM XXCoder: no thats 40w one
02:11 AM XXCoder: 60w is bit more
02:11 AM Wolf_: its 30w, 40w is max tube rating
02:11 AM Wolf_: so they market it as a 40w
02:11 AM pink_vampire: this is the one i'm thinking about http://www.kernlasers.com/
02:11 AM Wolf_: but it will burn out the tube at 40w constant
02:12 AM Wolf_: when I say 3-4k for a 100w thats a 120w max output tube
02:13 AM Wolf_: those are what? $10-15k?
02:20 AM Deejay: moin
02:21 AM XXCoder: Wolf_: aliexpress 100w is 3.8k or so
02:21 AM XXCoder: yeah
02:22 AM XXCoder: hey
02:22 AM Wolf_: yeah, i got a quote on a reci tube and psu a few months back
02:23 AM Wolf_: I have all the mirrors, mirror brackets, cutting head and beam combiner lens already
02:25 AM XXCoder: cool :)
02:26 AM XXCoder: I do want laser machine that can cut ploastic or wood but whatever
02:27 AM Wolf_: thats kinda my idea as well, but I want to be able to cut 3/4” ply wood
02:27 AM Wolf_: so 100w…
03:11 AM pink_vampire: https://www.youtube.com/watch?v=uMa1A9Q2iMM
03:12 AM pink_vampire: XXCoder: Wolf_^
03:12 AM XXCoder: looking
03:13 AM Wolf_: yeah, renishaw with a haas logo
03:14 AM pink_vampire: Wolf_: you missed the point..
03:14 AM Wolf_: ?
03:14 AM pink_vampire: http://i.imgur.com/94rzIqT.png?1
03:15 AM Wolf_: ah, nice
03:15 AM pink_vampire: http://i.imgur.com/nhoAbXq.png
03:16 AM XXCoder: pink_vampire: wow they used tool length probe with big tools too
03:16 AM XXCoder: and it spinning also
03:17 AM pink_vampire: the spinning is foe averaging the corners.
03:17 AM pink_vampire: for*
03:18 AM XXCoder: I notice its spinning backwards. good if dont wanna cut the probe lol
03:18 AM pink_vampire: lol!!
03:19 AM pink_vampire: i just look at the tool
03:19 AM pink_vampire: and i probe my parts all the time, so i'm fine with that.
03:20 AM pink_vampire: and with the g0704, you never have tool deflection, but you have machine deflection.
03:21 AM pink_vampire: XXCoder: Wolf_ ^
03:21 AM XXCoder: interesting
03:24 AM Wolf_: yeah
03:25 AM Wolf_: I still haven’t got my mill done
03:25 AM pink_vampire: I did a n easy fix for my z axis, but I'm nut sure if it work good.
03:26 AM archivist: they are looking for peak on the tool to get effective diameter
03:31 AM pink_vampire: archivist:
03:32 AM pink_vampire: archivist: do you know how the turret on a lathe get locked?
03:33 AM archivist: there are a few methods
03:33 AM archivist: ratchet, taper lever/pin
03:34 AM pink_vampire: taper?
03:35 AM archivist: the locking device will be tapered to remove backlash
03:35 AM Wolf_: collet w/ hydro draw system
03:35 AM Wolf_: same as the headstock
03:36 AM archivist: that is the tooling, Im talking about the turret itself
03:36 AM Wolf_: yeah so was I, but I haven’t pulled a turrent apart, yet
03:37 AM archivist: one had hooks
03:37 AM archivist: and mandraulic hold in force
03:38 AM archivist: this one http://www.archivist.info/cnc/works2008/P1010203.JPG
03:39 AM archivist: http://www.lathes.co.uk/britan/
03:39 AM archivist: revolting to use
03:40 AM pink_vampire: archivist: where is the turret on the pic?
03:41 AM archivist: top rear you can see tools sticking upwards http://www.lathes.co.uk/britan/img0.jpg
03:42 AM pink_vampire: i see that
03:42 AM archivist: the vertical lever you push back and pull forwards it hooks next, rotates
03:42 AM pink_vampire: i mean in the color one
03:42 AM archivist: same that is just a cover
03:43 AM archivist: without that cover you get covered in oil, (you get covered anyway with it)
03:43 AM archivist: spins anti clockwise
03:44 AM pink_vampire: i'm trying to looking for an image of the mechanism.
03:44 AM archivist: http://www.lathes.co.uk/britan/img2.jpg
03:44 AM archivist: you can see the hooks on a disk
03:44 AM pink_vampire: this is look like a ratchet
03:45 AM archivist: similar, the tools rest to set height
03:46 AM pink_vampire: there is no issue with ware over time?
03:46 AM archivist: http://www.lathes.co.uk/britan/img5.jpg
03:46 AM archivist: they sit on that edge
03:46 AM pink_vampire: so you lose the position in the turret
03:47 AM archivist: it is just a crazy idea
03:48 AM archivist: the spring under the ratchet/hook holds the tool onto the rest
03:48 AM pink_vampire: but after few spins it make some dent..
03:49 AM archivist: it is all oiled does not wear much at all
03:49 AM pink_vampire: I want to do something similar to my probe.
03:50 AM pink_vampire: but ratchet it is not a god option, because it get locked only in one direction
03:51 AM archivist: look also at how the mechanism works on a denford lathe, that is rotated by a stepper then reversed against the ratchet
03:52 AM m0n5t3r: https://www.youtube.com/watch?v=TXvrfDqYI3s related :)
03:52 AM pink_vampire: m0n5t3r: i share that here before few hours
03:52 AM archivist: make a hirth coupling http://moderncnc.com/v-tooth/hirthcouplings.html
03:53 AM pink_vampire: archivist: it is off the shelf product?
03:54 AM archivist: no you make
03:54 AM pink_vampire: how?
03:54 AM archivist: rotary table
03:54 AM pink_vampire: I don't have one..
03:54 AM archivist: but you need one :)
03:56 AM pink_vampire: https://en.wikipedia.org/wiki/Hirth_joint#/media/File:Hirth_joint.jpg
03:56 AM pink_vampire: it is something that I can take from any bicycle??
03:57 AM archivist: I would just change cutter from my usual when I made http://gears.archivist.info/gears/IMG_1214_hires.JPG
03:57 AM pink_vampire: do you want to make me one?
03:58 AM m0n5t3r: you can also go the clickspring way, with files :P
03:59 AM pink_vampire: m0n5t3r: i need it to be as repeatable as possible
03:59 AM archivist: you could even make it with an engraving cutter with the three axis you have
04:00 AM XXCoder: clickspring is file god
04:00 AM archivist: I think most clockmakers beat him
04:01 AM XXCoder: if he said in channel "I am file god" I would think "why is he saying that? we all know that already!" ;)
04:01 AM XXCoder: really? lol ok
04:02 AM archivist: clockmakers have to pass examinations if they want the certificates
04:02 AM pink_vampire: archivist: so it is just a V groove? on the same height?
04:03 AM archivist: old style fitters would also have to file stuff
04:03 AM archivist: pink_vampire, a taper so they mesh properly
04:04 AM pink_vampire: i can't cut something like that on my machine.
04:05 AM archivist: sure you can, you just cant think how yet
04:05 AM pink_vampire: if it not repeatable on all 3 axis, in less then half a degree it is waste of time.
04:06 AM pink_vampire: from the center of the joint to the tip of the probe, it is about 15 cm.
04:06 AM archivist: remember any problem is averaged over all teeth so gets removed/reduced enormously
04:07 AM archivist: you can just use a plain kinematic joint as well
04:08 AM pink_vampire: or it's going to swing...
04:08 AM pink_vampire: plain kinematic was my original idea.
04:09 AM pink_vampire: then i got a hdd motor, that is run super true.
04:09 AM pink_vampire: and i need to make a stopper for it.
04:10 AM pink_vampire: I just want to use it as a hinge
04:10 AM archivist: I already showed you a method for that
04:10 AM pink_vampire: i cant go 360 deg
04:10 AM pink_vampire: i have to go 180 and then -180
04:10 AM archivist: you dont have to
04:11 AM archivist: you can do what you like
04:13 AM pink_vampire: and, I try to avoids springs and stuff that slip on other stuff, to prevent damage
04:15 AM archivist: the best machines use springs fro precision location
04:18 AM pink_vampire: so only a leaf spring with ball bearing spot welded to it, that will locked between 2 cylinders will do the trick?
04:25 AM archivist: no welding needed
04:25 AM pink_vampire: http://www.kernlasers.com/wp-content/uploads/2016/09/LaserCELL-Brochure.pdf
04:25 AM pink_vampire: System Weight 3,700 lbs
04:25 AM pink_vampire: HOW????
04:26 AM archivist: renishaw and others press the ball into a hole
04:27 AM pink_vampire: but then you have to be concentric..
04:28 AM archivist: press fit means it the metal moves
04:29 AM archivist: it is really tight
05:26 AM XXCoder: pink_vampire: http://limpingchicken.com/2012/03/12/donna-williams-s-people-say-to-sign-language-interpreters/
05:27 AM XXCoder: another one https://deaffirefly.com/2012/01/20/shit-hearing-people-say/ this one I have experenced bunch of..
05:31 AM XXCoder: found it. https://www.youtube.com/watch?v=1cqv84ywBSE insanely funny
05:32 AM XXCoder: extremely sarastic answers that'd probably get real interpeter fired.
05:32 AM jthornton: morning
05:33 AM XXCoder: hey jthornton
05:33 AM XXCoder: suggest ya watch video heh
05:33 AM pink_vampire: XXCoder: i'm watching that https://www.youtube.com/watch?v=9oJxKkUosSk
05:34 AM XXCoder: https://www.youtube.com/watch?v=2Yy2r3LS6xw another one
05:35 AM jthornton: https://www.youtube.com/watch?v=hnMcWxh-ufE
05:35 AM XXCoder: pink_vampire: plating. interesting
05:37 AM XXCoder: jthornton: is it self-stabilizing?
05:38 AM XXCoder: or are you controlling it
05:38 AM jthornton: not in 2D mode
05:38 AM XXCoder: 2d mode?
05:38 AM jthornton: you take off in 2D and after your in the air you can switch to loiter
05:39 AM jthornton: 2d is you are in control with some stabilization but no altitude hold
05:40 AM XXCoder: interesting
05:40 AM jthornton: https://www.youtube.com/watch?v=6aRe948EKYs
05:41 AM XXCoder: did you see the 2 video links? heh
05:41 AM jthornton: yea
05:41 AM XXCoder: very sarastic answers all interpeters wish they can give
05:41 AM jthornton: lol
05:42 AM XXCoder: "irregular job"
05:42 AM XXCoder: that video wins serious
05:43 AM pink_vampire: O_o 6AM! light! I have to go and hide!
05:43 AM XXCoder: lol later
05:46 AM XXCoder: found another, super funny one but I dont really wanna keep linking more here :P
05:46 AM XXCoder: got text info of that? I'm quite dizzy and cant watch videos like that unfortunately
05:49 AM jthornton: http://eagletreesystems.com/Manuals/vector.pdf page 42 describes the modes
05:49 AM XXCoder: thanks
05:54 AM XXCoder: interesting
05:56 AM jthornton: I need to get the vector telementry to display on the taranis tx next
06:04 AM cpresser: ±/win 28
06:24 AM IchGucksLive: hi cnc guys /pink
06:25 AM XXCoder: hey ich
06:25 AM IchGucksLive: XXCoder: you look to many videos
06:25 AM IchGucksLive: so your wishlist gets spamd
06:25 AM XXCoder: wishlist?
06:26 AM IchGucksLive: things you like to build,buy od do
06:27 AM XXCoder: oh watching videos dont mean I add stuff to wishlist lol
06:27 AM IchGucksLive: sometimes even blond's get on the list
06:28 AM IchGucksLive: Q to the video "junky"
06:28 AM IchGucksLive: did you got or have seen a Vismach that realy cuts the stock
06:29 AM IchGucksLive: im working on it but not geting thrue
06:29 AM IchGucksLive: minigl does not support booleon
06:31 AM IchGucksLive: so to sub tool from stock
06:31 AM IchGucksLive: woudt be easy
06:32 AM IchGucksLive: but if it has been taht way it woudt be implementet into vismach.py at first
06:32 AM IchGucksLive: jthornton: dident you got a example of stock cutting
06:32 AM IchGucksLive: arwallin wars into it as OCL
06:32 AM jthornton: stock cutting?
06:32 AM IchGucksLive: inside vismach
06:32 AM IchGucksLive: someone here made a progress on this
06:34 AM jthornton: I've never messed with vismachine
06:35 AM IchGucksLive: you shoudt its fun all the time
07:01 AM archivist: there was an experimental stock cutting in vismach many years ago
07:03 AM IchGucksLive: that is what i am refering 2
07:54 AM IchGucksLive: im off till later
10:55 AM phipli: afternoon
11:20 AM archivist: before cnc there was http://www.ebay.co.uk/itm/Vintage-antique-hand-cranked-blacksmiths-wheelwrights-pillar-drill-press/172797484133
11:31 AM JT-Shop: phipli: https://www.youtube.com/watch?v=hnMcWxh-ufE
11:35 AM Frank_10: hi guys; i've been trying to set up the x axis tandem.motors to work good but i cant seem.to make them.move.at.the same speed
11:35 AM Frank_10: on ini file the tandem motor is setup tto velocity control or control type 0
11:36 AM Frank_10: thats the only.differenc i could see
11:36 AM Frank_10: sorry; on hal.file
11:37 AM Frank_10: is it supposed.to be.like that or.i should change.both to.position control.typr
11:37 AM JT-Shop: servo with encoder feedback to lcnc?
11:38 AM Frank_10: nope; it.closes.to driver
11:38 AM Frank_10: step dir command
11:38 AM JT-Shop: position command for step and direction
11:39 AM Frank_10: tried to make then.both move.on position control.but tandem.motor.doesnt move now
11:51 AM JT-Shop: I wish I still had the config I made to run the gantry video...
12:13 PM phipli: JT-Shop: how big were those props?
12:14 PM phipli: archivist: infinite variable speed, advanced feedback system....
12:15 PM archivist: phipli, the genny now charges its battery, and produces 415/240/240/240 like a goodun
12:16 PM phipli: :)
12:16 PM phipli: congratulations
12:16 PM archivist: had to remagnetise the dynamo this morning
12:17 PM archivist: not done that for best part of 40 years
12:17 PM phipli: stroke a magnet on it?
12:17 PM phipli: or how?
12:17 PM archivist: nah just put 12v direct on the field connection
12:17 PM phipli: ah right
12:17 PM malcom2073_: archivist: I've heard of people having to do that, how long was it off?
12:18 PM archivist: some years
12:18 PM malcom2073_: Ah heh
12:18 PM archivist: it was also done if you converted positive earth to negative
12:18 PM malcom2073_: I guess that drains it off?
12:19 PM malcom2073_: Or rather, the field needs togo the other way?
12:19 PM archivist: it is only a weak magnet in the body of the dynamo
12:20 PM malcom2073_: Yeah, the 12v circuit on my old onan generator is toasted, I keep a 110v->12v charger on it when it's running, been told if I let the 12v drain out completely it'll kill the field
12:20 PM archivist: of course then I found the new ammeter backwards
12:21 PM archivist: although I tickled the field when stationary, it still didnt work, doing it while running was more effective
02:41 PM nos__ is now known as nos
03:12 PM JT-Shop: phipli: 10"
03:15 PM phipli: That thing can probably carry you into town!
03:16 PM JT-Shop: with those props on 3S I'll have 2680 grams of thrust
03:16 PM phipli: what does it weigh?
03:17 PM JT-Shop: right now about... I forgot let me see
03:18 PM JT-Shop: 900 grams without battery or camera
03:21 PM phipli: so about 1.5kg of payload capacity?
03:21 PM phipli: could deliver parts to clients? :)
03:22 PM jdh: amazon delivery
03:22 PM phipli: JT delivery
03:28 PM Tom_L: JT-Shop, does it auto stabalize?
03:30 PM JT-Shop: http://eagletreesystems.com/Manuals/vector.pdf go to page 42 for a description of all the modes
03:30 PM Tom_L: i know little to nothing about em, just curious
03:31 PM Tom_L: seems that would make it a dream to fly
03:33 PM Tom_L: this must be an add on?
03:39 PM JT-Shop: the link is for the Flight Controller FC for short and it is what controls the motors, this one comes with GPS V2, compass, On Screen Display OSD for short, flight data recorder, built in altimeter etc
03:39 PM JT-Shop: you can program in way points on google maps and make it fly a mission then return to home
03:41 PM JT-Shop: phipli: it's coming out a little heavier than I calculated 1130 grams and it looks like about 1250 grams when the 4100 mAh 3S battery arrives if they didn't lie about the weight lol
03:41 PM Tom_L: sounds like alot of fun
03:41 PM Tom_L: or liability..
03:43 PM JT-Shop: I don't plan on flying very far from home base with this one, air time is too short to go very far, I'm figuring 15 minutes air time max
03:45 PM JT-Shop: it's a funny waiting game, you figure out the next item you need and wait and wait and wait for it to arrive lol
03:48 PM XXCoder: if you're not waiting for something, you're dead. lol
03:50 PM chopper79: Afternoon all....
03:52 PM JT-Shop: enjoying some of this cooler weather over there?
03:54 PM chopper79: I am working with a 5i25 and 7i76. I have motor movement so all that is good, but I am not able to get any inputs to work (limits,estop). I am using a 12v power supply for vin and field power and ground connected to TB1 connector. I can verify that I have 12v on each field pin along with vin on this connector. Also I have ground on that correct pin on this connector. Any ideas on where I should be looking for a reason I do not have any inputs working wh
03:55 PM chopper79: Using inouts 0-4 on TB6
03:55 PM chopper79: *inputs
03:57 PM JT-Shop: you have 12v+ > switch > TB6 Pin 1 connected
03:58 PM JT-Shop: and TB1 Pin 1 12v+, Pin 8 0v
03:59 PM chopper79: I have 12v+ to pin 1 and 0v to pin 8 on TB1. From there it goes to Pin2 TB1 to limit and from limit to TB6 pin 0 (pin1)
04:01 PM JT-Shop: that should work
04:01 PM chopper79: W1 is in left position so only vfield needs power and it connects to VIN. All these pins show 12v+ where they should.
04:02 PM chopper79: I can see all the pins available also. Just for some reason I can not make then change state in LCNC. When I disconnect wiring I can put my VOM on TB1 pin wire and the wire going to the inout on TB6 while pressing the limit and I can change the state on my VOM.
04:03 PM chopper79: Not sure why lcnc is not seeing these thoug
04:03 PM JT-Shop: how are you viewing the pin state?
04:03 PM chopper79: Using hal config, hal meter
04:03 PM chopper79: outside of lcnc I use my VOM
04:04 PM JT-Shop: using the watch window in hal config?
04:04 PM chopper79: work with it for about 3hrs and can not find anything
04:04 PM chopper79: Yes
04:05 PM chopper79: Also using hal meter
04:05 PM chopper79: I have never came across this situation before so it has me stumped
04:06 PM JT-Shop: both CR1 and CR2 are lit up?
04:06 PM chopper79: Yes
04:07 PM chopper79: hmm.... just thought of something
04:07 PM JT-Shop: glad you did, I'm out of thoughts lol
04:07 PM chopper79: All my other setups have a flashing led when in use. These are solid.
04:08 PM chopper79: Need to see if there is a setup and operation mode maybe being the issue
04:08 PM pcw_home: The 7I76 has no green flashing LED
04:08 PM chopper79: well shoot then
04:08 PM JT-Shop: The 7I76 has two yellow status LEDs for power monit
04:08 PM JT-Shop: oring, CR1 and CR2. CR1 on
04:08 PM JT-Shop: the top left side of the 7I76 monitors 5V power. CR
04:08 PM JT-Shop: 2 on the top right side of the 7I76
04:08 PM JT-Shop: monitors field power. Both LEDs must be illuminated for normal operation.
04:08 PM pcw_home: what does the 7I76 read for field voltage?
04:08 PM chopper79: Both are on JT
04:09 PM chopper79: 12v
04:09 PM pcw_home: from the 7i76 field voltage hal pin?
04:09 PM chopper79: sorry
04:09 PM chopper79: not sure ..... sorry I am not infront of this machine.
04:11 PM chopper79: I know that does not help much. Just trying to get some ideas together so when I go there tomorrow and work on it I am not lost still
04:11 PM pcw_home: some modes allow you to read the field voltage, that may give as clue
04:11 PM pcw_home: do all pins read 0 regardless of input?
04:12 PM pcw_home: do you have any errors from LinuxCNC/Axis?
04:12 PM chopper79: May be a dumb question but I just plugged the 5i25 in and made my connections. Went into pnconfig and setup the hal config. I did not flash the 5i25. Could that be the issue?
04:12 PM chopper79: No errors.... motors all function gret
04:13 PM chopper79: just input output issue,
04:13 PM pcw_home: if the 7I76 pins show up, its not a firmware issue
04:13 PM chopper79: all pins show up
04:14 PM chopper79: Just trying to rule that out
04:14 PM pcw_home: do the field outputs work?
04:14 PM chopper79: not that I could see or test.
04:15 PM pcw_home: you can just setp one true to test
04:15 PM chopper79: I can tomorrow when around the machine again.
04:19 PM chopper79: using a 12v supply.... could voltage be to low for the inputs to sense the change? I typically use 24v supplies for this but was forced to use a 12v this time.
04:20 PM chopper79: 8-32v needed for inputs so should be fine I would think
04:22 PM pcw_home: No, the input threshold is set to 60% (rising input) and 40% (falling input) of field voltage
04:23 PM pcw_home: so at 12V the thresholds will be 7.2V and 4.8V
04:23 PM chopper79: That is what I was thinking. I am not sure then on what it could be.
04:24 PM pcw_home: I dont think I've seen an error like this before
04:24 PM chopper79: I bypassed the limits but just jumping a wire from a vfiled output to the input desired and still did not change state. This was just a siimple using a wire as it was a momentary switch.
04:25 PM chopper79: I am not a pro but after 12-14 system setups I have not either.
04:25 PM pcw_home: so all inputs read 0 regardless of input level?
04:25 PM chopper79: yes
04:27 PM chopper79: Well I think I found the issue...... Dumb moment for me.
04:27 PM Deejay: gn8
04:30 PM chopper79: Board is mounted in an odd orientation so..... output connector on TB6 or not input. (BIG FACE PALM) Sometimes it takes talking to peers to find the stupid mistakes.
04:30 PM chopper79: *outputs are not inputs
04:30 PM Tom_L: sometimes we answer our own questions
04:31 PM chopper79: yes we doafter making a fool out of yourself on here...haha
04:31 PM Tom_L: that just makes i one you won't soon forget :)
04:32 PM chopper79: I will remeber this for sure.
04:32 PM Tom_L: i was quite tickled last night to finally get everything back in order on my mill after the hdd crash
04:32 PM Tom_L: updated 300+ packages and installed 2.7.11 and hit the cutters
04:33 PM chopper79: always nice
04:33 PM Tom_L: ran without a hitch
04:33 PM Tom_L: nice feeling for sure
04:34 PM chopper79: I have one last thing to do on this mill for the local maker space and that is make their odd spindle drive work with lcnc. No documentation so I am running into a wall on it so far.
04:39 PM chopper79: The mill is an old syil x3. The spindle drive had a lcd on the front of mill. That was removed and now I have to get it working witht he 7i76. The board is lables but not sure what is going to what.
05:48 PM Frank_: guys, im having a hard time trying to find a way to config 2 servos that take step +dir closed loop on drive, on the same axis
05:48 PM Frank_: anyone can guide me where ?
06:01 PM JT-Shop: if your using master and you should there is an example for gantry, two joints and one axis
06:04 PM Frank_: should i be using master? my gantry is really rigid and wont be able to home different motors, acctually im afraid that it might end up binding because of the shitty racks
06:04 PM Frank_: i have 1 home switch for each axis
06:05 PM XXCoder: is it over-constrained?
06:05 PM Frank_: sorry whats that :/
06:05 PM Frank_: as far as i could go is pncconf stepgen tandem axis, but one motor moves at a slower rate
06:06 PM Frank_: in hal it sets the tandem axis to velocity control and the master one to position control i believe
06:07 PM JT-Shop: might be time to leave the crib and open the configuration files and start looking around for the problem
06:08 PM sync: well, then you assume your portal is always not bent
06:08 PM sync: and you will be able to flex any portal a lot
06:08 PM XXCoder: hard to explain over-constrained problem, as I barely know that
06:08 PM * JT-Shop listens to ELP From the Beginning then retires for the night
06:10 PM XXCoder: Frank_: https://www.fictiv.com/hwg/design/helpful-design-constraints-vs-over-constraint-how-to-find-the-sweet-spot
06:10 PM XXCoder: might be helpful
06:11 PM Frank_: thanks im chekign right now
06:11 PM XXCoder: the table example is fanastic.
06:12 PM Frank_: okey i know what you mean
06:12 PM Frank_: it might be overconstrained in the way that the racks arent precise enough....
06:12 PM Frank_: on each side of the gantry
06:12 PM Frank_: when i put them side by side i could see about .2/
06:12 PM Frank_: .5mm gap
06:12 PM Frank_: will have to check if they bind up
06:14 PM XXCoder: thats not overconstrant just part problems
06:47 PM Loetmichel: maaan, sometimes my thick fingers get me good... someone on reddit had his pet rat bite thru his joystick-cable... i had a broken USB cable laying around so i decided to make a quick vid to show how to solder that... and promptly ripped out one of the data lines ;) (could also be that that was the fault of the cable, it WAS broken to begin with..) -> https://www.youtube.com/watch?v=i-k9I988J38
06:50 PM XXCoder: lol
07:00 PM XXCoder: Loetmichel: interesting video
07:01 PM Loetmichel: interesting good or interesting bad?
07:01 PM Loetmichel: :-)
07:01 PM XXCoder: both
07:01 PM XXCoder: kidding good
07:02 PM XXCoder: autofocus thing was only bad thing about it
07:03 PM Loetmichel: yeah, to say it with some famous youtuber: "FOCUS, YOU FU**!"
07:04 PM XXCoder: when im at bad place dizzy-wise, focus issues makes video unwatchable
07:04 PM XXCoder: I had to look away those sections of your video
07:04 PM CaptHindsight: anyone ever cnc wood to make barrels?
07:04 PM Loetmichel: it was my samsing Note3... not the newest in camera technology... mounted on a big bottle of coke by a blob of kiddie moddeling clay... did i say that it was made pretty impromptu? ;)
07:05 PM XXCoder: better than my handheld samsung s4 phone lol
07:05 PM XXCoder: https://www.youtube.com/watch?v=xF8erDoJlsY enjoy the handshaking glory
07:06 PM Loetmichel: hihi
07:06 PM Loetmichel: its ok, have seen worse
07:10 PM XXCoder: yeah
07:10 PM XXCoder: I need some decent yet cheap camera

07:40 PM sync: I always wonder how good the grain structure is with those particle colliders
07:42 PM _nexxus__ is now known as _nexxus_
09:31 PM CaptHindsight: sync: there's an electron microscope shot of the grain, it's pretty porous in my book
09:32 PM CaptHindsight: sync: I've seen sponges with more density https://img.newatlas.com/desktop-metal-3d-printers-1.jpg?auto=format%2Ccompress&fit=max&h=670&q=60&w=1000&s=e007e31fb3614f6b1fb9afb8ce886806
09:33 PM CaptHindsight: that looks porous enough to float on water even if its copper
09:35 PM CaptHindsight: https://img.newatlas.com/desktop-metal-3d-printers-14.jpg?auto=format%2Ccompress&fit=max&h=670&q=60&w=1000&s=9a28a8a7ee1b2dea52034cf42d1eb90e I'd like to see a cross section of this part
09:37 PM CaptHindsight: so this one operates like a powder spreader similar to SLS but uses an inkjet to print a binder onto the metal powder layer by layer
