12:12 AM rebecca: this is probably a terrible idea... but i'm pondering buying one of these, cutting the shank shorter and.. chucking it up on my spindle.
12:14 AM rebecca: https://www.banggood.com/S06K-SCLCR06-Lathe-Turning-Tool-Holder-With-10pcs-CCMT060204-Carbide-Inserts-p-1123191.html
12:14 AM rebecca: has anyone tried this already?
12:30 AM xxcodercnc: heys
12:30 AM xxcodercnc: tachmeter sensor works :)
12:30 AM xxcodercnc: gonna try 5v and see if works.
12:51 AM xxcodercnc: wow all silent
01:15 AM XXCoder: hey archivist
01:30 AM IchGucksLive: morning from Germany
01:31 AM XXCoder: hey ich
01:31 AM IchGucksLive: its getting sunny this morning
01:31 AM XXCoder: I got question
01:31 AM IchGucksLive: time to set up all garden work
01:31 AM XXCoder: you know what is max input KHZ for BOB?
01:31 AM IchGucksLive: the BOB i use
01:32 AM XXCoder: because my spindle can do 12000 * 2 triggers per rotation
01:32 AM IchGucksLive: 20khz
01:32 AM XXCoder: 20k cycles per cycle
01:32 AM XXCoder: thats well above 12000 rotations per minute * 2
01:34 AM XXCoder: 24000 triggers per minute / 60 seconds in minute = 400 triggers per second
01:34 AM XXCoder: thanks ich
01:34 AM IchGucksLive: NP
01:35 AM IchGucksLive: XXCoder: to be clear the ECP/EPP has a 2Mbps speed but you cand retch this
01:35 AM IchGucksLive: the Bob has a double safty chain
01:35 AM XXCoder: 24000 seemed huge number but I realized its per minute. os yeah lol
01:36 AM Deejay: moin
01:36 AM XXCoder: I was thinking 24khz but it wasnt that lol
01:36 AM XXCoder: hey
01:36 AM IchGucksLive: 400HZ is a good to count pulse in
01:37 AM IchGucksLive: use a software encoder
01:37 AM XXCoder: yeah though I cant use 12v input
01:37 AM XXCoder: I need to use resistor, 10k to ground
01:37 AM XXCoder: someone said that will more than halve v to approx 5v
01:39 AM IchGucksLive: XXCoder: the bob's OP can take 12V on 1.5k
01:39 AM IchGucksLive: its the same as on the TB6600 Leadshine M series
01:40 AM IchGucksLive: But safty first try out
01:40 AM XXCoder: a second
01:41 AM XXCoder: https://www.aliexpress.com/item/High-Quality-Upgraded-5-Axis-CNC-Breakout-Board-for-Stepper-Motor-Driver-Mach3-USB-Cable/32738646022.html
01:41 AM XXCoder: this one?
01:41 AM IchGucksLive: yes
01:41 AM IchGucksLive: it has the 817 optocoplers
01:43 AM IchGucksLive: XXCoder: on URI calculate 7V to be vanished as 5mA to be used
01:44 AM IchGucksLive: 7/0,005
01:44 AM XXCoder: sensor output is 12v
01:44 AM XXCoder: tiny mA though if I recall right
01:46 AM IchGucksLive: ONE of this = Sensor ? https://www.reichelt.de/Optokoppler/ELI-TR8102/3/index.html?ACTION=3&GROUPID=3046&ARTICLE=146681
01:47 AM XXCoder: no a second
01:48 AM XXCoder: still looking
01:49 AM IchGucksLive: XXCoder: you can alo use a Z-Diode
01:49 AM IchGucksLive: 5.1V
01:50 AM IchGucksLive: XXCoder: shematic https://electronics.stackexchange.com/questions/80597/optocoupler-input-protection
01:51 AM XXCoder: cant find my order so looing for similiar item now
01:51 AM IchGucksLive: NP
01:51 AM IchGucksLive: XXCoder: doesent matter
01:51 AM IchGucksLive: it takes 24V
01:51 AM XXCoder: https://www.aliexpress.com/item/New-4-Digital-Red-LED-Tachometer-RPM-Speed-Meter-Proximity-Switch-Sensor-NPN-3-Wires/1980583177.html
01:52 AM IchGucksLive: a standard NPN
01:52 AM XXCoder: https://www.aliexpress.com/item/New-Blue-LED-Tachometer-RPM-Speed-Meter-Hall-Proximity-Switch-Sensor-NPN-free-shipping/32330751435.html
01:52 AM XXCoder: thats closert o mine
01:53 AM XXCoder: funny thing display dont work because I has 2 magnets and it expects one
01:53 AM IchGucksLive: you got one that takes your speed
01:53 AM IchGucksLive: the standard Ref Inductive can only take 300Hz
01:54 AM IchGucksLive: and you need 400
01:54 AM XXCoder: so sensor wont work either?
01:54 AM XXCoder: or is it just display, as I dont really care about that one
01:55 AM IchGucksLive: it can mabe clear on 8k RPM above it is not that working
01:55 AM IchGucksLive: and aboce 11k it wont ragionise
01:55 AM IchGucksLive: above
01:55 AM XXCoder: yeah it dont work with my tests lol
01:55 AM IchGucksLive: you need a optical one
01:55 AM XXCoder: so it is both display and sensor that dont work above 300 hz?
01:56 AM IchGucksLive: the display workes on 0,2seconds
01:56 AM IchGucksLive: as it counds the middle
01:56 AM IchGucksLive: XXCoder: why not get your own 6parts solded togeter
01:57 AM IchGucksLive: with a real working need
01:57 AM XXCoder: make my own sensor?
01:57 AM IchGucksLive: yes a sensor for 40cents
01:57 AM IchGucksLive: the optocopler at 30 cents
01:57 AM IchGucksLive: the Tiny at 1,2
01:58 AM IchGucksLive: some recistors 20cents
01:58 AM IchGucksLive: and the LCD at 2
01:58 AM IchGucksLive: or use a EAN at 4 and display all you net in DIGI
01:58 AM XXCoder: how did you know that BOB has pc817 opticouplers?
01:58 AM IchGucksLive: DOG-M
01:59 AM IchGucksLive: i got 4 to my left in armlength and 10 in the cabinet to the right 5foot away
02:00 AM IchGucksLive: its a chain of Pc817 74hct014
02:00 AM IchGucksLive: to the parport
02:00 AM XXCoder: well
02:01 AM IchGucksLive: a 3D print case
02:01 AM IchGucksLive: so you got good stuff
02:01 AM XXCoder: is there magnet sensor that can go more than 400 hz?
02:01 AM IchGucksLive: and a real nice projekt
02:01 AM XXCoder: I already expoied magnets in spindle fan
02:05 AM XXCoder: I suppose I can pry one off
02:05 AM XXCoder: leaving it one, so 200 hz
02:05 AM XXCoder: but problem is that fan will be slighgtly imbalanced which isnt goof ror 12000 rpm
02:06 AM IchGucksLive: im not that electronic guy you might thik
02:06 AM IchGucksLive: so im off this discussion here
02:07 AM IchGucksLive: there are plenty of different out
02:07 AM XXCoder: "Response frequency: 100HZ"
02:09 AM IchGucksLive: ok i looked at Datasheets
02:09 AM IchGucksLive: ti says if you go for 600hz
02:10 AM IchGucksLive: you nedd to make shoure that the Metall on the rotation device is 6times the wide of the sensor in retch as it rotates
02:11 AM IchGucksLive: so 6x sensor wide on and 6x sensor wide off
02:11 AM IchGucksLive: will goive you the 600hz klear
02:11 AM IchGucksLive: clear
02:11 AM XXCoder: thats for induction I think
02:11 AM IchGucksLive: yes
02:12 AM XXCoder: mines magnet sensor not induction
02:12 AM IchGucksLive: then try it out
02:12 AM IchGucksLive: use a oszisloscope at 20USD
02:12 AM XXCoder: theres ossiloscope for $20?
02:13 AM IchGucksLive: to see a clear signal
02:13 AM XXCoder: cant spell that word either
02:13 AM IchGucksLive: google picture DS0138
02:14 AM IchGucksLive: or your faforit sellor
02:14 AM XXCoder: ahh that one
02:14 AM IchGucksLive: i use it almost every day
02:14 AM XXCoder: require computer or standalone?
02:14 AM IchGucksLive: standalone
02:14 AM IchGucksLive: 9V
02:14 AM IchGucksLive: Block batterie
02:14 AM XXCoder: I saw one for $5 but was project solder
02:15 AM IchGucksLive: it is cool to solder
02:15 AM IchGucksLive: 2hr intensive Brain
02:15 AM XXCoder: https://www.aliexpress.com/item/NEW-DS0138-Digital-Oscilloscope-DIY-Kit-Probe-Unsoldered-Workshop-STM32-200khz/32802757387.html
02:16 AM IchGucksLive: as i said 20 box
02:16 AM IchGucksLive: ok i need to close
02:16 AM XXCoder: add https://www.aliexpress.com/item/New-Clear-Acrylic-Case-Box-Shell-for-DSO138-2-4-TFT-Digital-Oscilloscope/32804034040.html
02:16 AM XXCoder: and done heh thanks
02:16 AM IchGucksLive: hope i did not make you more confusing than youve been bevore
02:17 AM IchGucksLive: XXCoder: its only the case
02:17 AM XXCoder: just a lot to figure out lol
02:17 AM XXCoder: I know
02:17 AM XXCoder: its to enclose the earlier link lol
02:18 AM IchGucksLive: Bye till later
02:18 AM XXCoder: later
02:22 AM archivist: some of the really cheap scopes dont like 12v DC in
02:22 AM XXCoder: hey good morning arch
02:23 AM XXCoder: seems that magnet sensor I use maxs out at 300 hz and mine goes to 400 hz
02:23 AM XXCoder: so it doesnt work
02:23 AM XXCoder: in least thats what i understood from him
02:28 AM archivist: without a scope you cannot see
02:28 AM Deejay: moin
02:29 AM XXCoder: hey another deejay
02:29 AM XXCoder: archivist: yeah want a scope but tend to be bit expensive
02:29 AM XXCoder: HMM found this http://www.ebay.com/itm/DC-5-24V-1000Hz-Hall-Effect-Sensor-Proximity-Switch-3-Wire-IP67-for-3D-Printer-/361934714650
02:29 AM XXCoder: it maxes out at 1000 h
02:29 AM XXCoder: which is more than twice mine can go to
02:42 AM XXCoder: archivist: wow cant find any magnet sensor thats fast enough
02:43 AM archivist: 1000 is fast enough, do the maths
02:43 AM XXCoder: im not too sure "Switching frequency" means what I think it means
02:44 AM archivist: read the data sheet
02:46 AM XXCoder: where?
02:47 AM XXCoder: whats nice is that it is also 5v-24v
02:47 AM XXCoder: so can just use 5v and directly connect output to BOB, unless BOB really supports 12v
02:48 AM archivist: inputs are often pulled up to 12v
02:48 AM XXCoder: so i can just use 12v output directly connect to BOB opti input
02:49 AM archivist: you need to check,
02:50 AM archivist: also any opto in the bob has a speed limit
02:50 AM XXCoder: yeah its apparently 20khz
02:50 AM XXCoder: which is FAR above what I need, which is 400 hz
02:51 AM archivist: dont believe everything said on the internet
02:52 AM XXCoder: yeah. though way I figure even if it is 10% its still 1000Hz and I need 400Hz
02:54 AM archivist: you need to see what the load resistance for the opto is, if 10k then the max freqency is 1.5 khz
02:55 AM XXCoder: problem with chinese stuff is usually no board design info
02:55 AM XXCoder: "wonderful"
02:55 AM archivist: measure or look at devices
02:57 AM XXCoder: https://ae01.alicdn.com/kf/HTB1OeRrOpXXXXcWaXXXq6xXFXXXc/High-Quality-Upgraded-5-Axis-CNC-Breakout-Board-for-Stepper-Motor-Driver-Mach3-USB-Cable.jpg
02:57 AM XXCoder: chips at top of picture is optos right?
02:57 AM XXCoder: 5 of em
03:01 AM archivist: each one has a pull up
03:02 AM XXCoder: ok
03:02 AM XXCoder: I found more info also now reading
03:02 AM archivist: they also have series resistor on each input
03:03 AM XXCoder: yeah see it
03:06 AM XXCoder: you got any advice on designing a board to mount electrics on?
03:22 AM phipli: Tom_itx, "...TB range yet" I think so... I'll double check
03:24 AM phipli: Tom_itx, there is a 1TB version of the disk I got, price scales approximately linearly
03:28 AM XXCoder: ebay paypal payment system is borked
03:28 AM XXCoder: wtf
03:30 AM phipli: What did it do?
03:31 AM XXCoder: open "window" login, click login
03:31 AM XXCoder: it shows waiting lock icon
03:31 AM XXCoder: it blanks, leaving "window" blank and cant browse anywhere else
03:32 AM XXCoder: chromium works ok so i guess its firefox specific
03:32 AM phipli: press f11
03:32 AM phipli: usually gets your URL bar back
03:32 AM XXCoder: no its still there. i said "window" aka fake one inside website
03:32 AM phipli: ah right
03:33 AM XXCoder: well finger wire channels and hall sensor ordered
06:04 AM jthornton: morning
06:05 AM XXCoder: hey jt
06:05 AM Deejay: good afternoon, gents
06:05 AM XXCoder: I fixed spindle connection and also checked npn sensor
06:05 AM jthornton: hey dj
06:05 AM XXCoder: it dont seem able to handle my machine rpm
06:05 AM XXCoder: 400 hz is above its max of 300 hz
06:13 AM jthornton: had to turn the dang heat on
06:40 AM XXCoder: hmmm
06:40 AM XXCoder: https://membarrier.wordpress.com/2017/04/12/qnx-7-desktop/
06:40 AM XXCoder: qnx as linuxcnc os?
06:40 AM XXCoder: it is very realtime os
06:43 AM XXCoder: I still have qnx4 demo disk somewhere I think
06:43 AM XXCoder: https://youtu.be/K_VlI6IBEJ0
07:15 AM Tom_itx: HEAT!
07:15 AM jthornton: I wonder what I have laying around to open the coop door automagily
07:16 AM Tom_itx: clear sky with no chance of snow here
07:16 AM Tom_itx: timer or other trigger?
07:16 AM jthornton: photo cell I think
07:17 AM Tom_itx: built in delay
07:17 AM Tom_itx: for closing
07:18 AM jthornton: I noticed some vids show a delay for closing and opening
07:18 AM Tom_itx: cell path should be broken for a few sec before triggering, yes
07:19 AM jthornton: hmm I have two 90vdc linear actuators
07:19 AM Tom_itx: tiny10 would do all that
07:19 AM Tom_itx: sot23-6
07:20 AM jthornton: I have a bunch of ardweenies can I run them off of 12v?
07:20 AM Tom_itx: not unless you regulate it to 5
07:20 AM Tom_itx: or 3.3
07:20 AM Tom_itx: i don't know if they regulate it onboard
07:20 AM jthornton: I think I have some 12v - 5v regulators in the pile
07:21 AM Tom_itx: i don't speak ardweenian
07:21 AM Tom_itx: just the native tongue
07:21 AM jthornton: lol, I know
07:22 AM Tom_itx: http://tom-itx.no-ip.biz:81/~webpage/temp/tiny/tinyTPI1.jpg
07:22 AM Tom_itx: that would do it
07:22 AM Tom_itx: slap 5v on it
07:23 AM jthornton: little bitty guy
07:24 AM Tom_itx: onboard 12Mhz osc
07:25 AM Tom_itx: 4 io
07:29 AM jthornton: program that with your programmer?
07:34 AM jthornton: https://www.youtube.com/watch?v=4BuGN4ag_fk
07:37 AM Tom_itx: yes
07:42 AM phipli: jthornton, remember not to force the door shut
07:43 AM phipli: let gravity drop it
07:43 AM phipli: so you don't crush a chicken
07:43 AM jthornton: good point, don't want half and half chickens
07:43 AM phipli: based on how the chickens behave, I'd trigger it from light
07:43 AM phipli: sun comes up = open
07:43 AM phipli: not much sun = close
07:43 AM jthornton: yea I have a photocell control for a security light
07:45 AM jthornton: put a timer to delay if needed
07:45 AM phipli: tell me how it goes
07:45 AM jthornton: ok
07:46 AM phipli: since we lost the head chicken, the girls have started making a terrible racket in the mornings
07:46 AM jthornton: watching a video and he uses this motor https://www.amazon.com/gp/product/B00O7IHVIA/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B00O7IHVIA&linkCode=as2&tag=latoho-20&linkId=YRT5FSD36KVWZDGL
07:46 AM phipli: worried the neighbours will get irritated and so should probably get the door automatically opening for them
07:46 AM jthornton: I wonder why he needs this stepper driver board? https://www.amazon.com/gp/product/B00NJOTBOK/ref=as_li_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B00NJOTBOK&linkCode=as2&tag=latoho-20&linkId=6ORHJA4MQJKJNVDB
07:47 AM phipli: I have some RC style geared dc motors somewhere
07:47 AM phipli: also have a spare leadscrew... but that is probably overkill
07:47 AM phipli: some threaded bar might do
07:49 AM Tom_itx: JT-Shop, it's just a Hbridge for the motor
07:50 AM Tom_itx: they're just calling it a stepper driver
07:50 AM jthornton: ok
07:50 AM Tom_itx: any ole hbridge should do
07:50 AM Tom_itx: i'd use a 5v relay
07:51 AM jthornton: yea that makes more sense
07:51 AM Tom_itx: HE101 is 5v tolerant and smt
07:51 AM Tom_itx: hamlin
07:51 AM Tom_itx: probably big enough for that
07:52 AM Tom_itx: and has builtin diodes
07:52 AM Tom_itx: or one of the ardweenie relays all over ebay
07:53 AM jthornton: https://www.amazon.com/10pcs-SRD-DC5V-SL-C-power-Electromagnetic-Relays/dp/B01FDGUH12/ref=sr_1_2?ie=UTF8&qid=1494073306&sr=8-2&keywords=5vdc+relay

07:54 AM Tom_itx: already mounted
07:54 AM Tom_itx: i'm using those on my spindle control :D
07:55 AM jthornton: hmm ebay is cheaper than amazon

07:55 AM Tom_itx: can't beat that
07:56 AM malcom2073: Love china for those cheap things
07:56 AM jthornton: might get here by July...
07:56 AM Tom_itx: you can find em already in the US, you just pay a little more
07:57 AM jthornton: yea $6 to get it monday

07:58 AM Tom_itx: ships from KC
07:59 AM Tom_itx: won't get much closer than that probably
07:59 AM jthornton: $6 with shipping same as amazon with free shipping

08:00 AM Tom_itx: NY, free shipping
08:20 AM jthornton: hmm I have some LM340T5 chips I wonder what they do
08:21 AM Tom_itx: linear regulator
08:21 AM Tom_itx: 5v
08:22 AM jthornton: ok, I can use that with a 12v battery to power the chip
08:22 AM Tom_itx: i doubt you really need a chip for that project
08:23 AM Tom_itx: mechanical limits for the motor
08:23 AM Tom_itx: the yard sensor should have a switch on it
08:23 AM Tom_itx: up at dawn, down at dusk
08:25 AM jthornton: I think you need some time delays like for the lock you need extra down time after hitting the limit
10:02 AM zeeshan: !seen rob_h
10:02 AM the_wench: last seen in 2017-05-05 20:35:54GMT 18:54:54 ago, saying Quit: Leaving
10:02 AM gregcnc: zee is your lathe lathing yet?
10:12 AM archivist: or holding the floor down
10:50 AM IchGucksLive: hi all from a drippin rain in germany
10:51 AM Jymmm: Ah, the german weatherman
10:51 AM IchGucksLive: not good mood to them as they where always wrong
10:51 AM Jymmm: IchGucksLive: That would be YOU
10:51 AM IchGucksLive: ROFL
10:52 AM IchGucksLive: i cdid a green house today
10:52 AM Jymmm: IchGucksLive: You give a weather report every time you join, so you MUST be a weatherman
10:52 AM IchGucksLive: so im now without weather
10:52 AM Jymmm: as is every person on the planet =)
10:53 AM IchGucksLive: Jymmm: so you see its a live join
10:53 AM IchGucksLive: not as most here only join on pc run up
11:14 AM IchGucksLive: im off till later
11:49 AM malcom2073: He is very much like a weatherman, joins, tells us the weather, then leaves
11:51 AM roycroft: bummer
11:52 AM roycroft: i'm going to run out of paint shortly
11:52 AM roycroft: and i can't get more until Monday.
11:52 AM roycroft: this new paint is really nice, but it's super sticky and goes on really heavily
11:52 AM roycroft: that's good for machinery and machinery stands
11:52 AM roycroft: but i did underestimate how much i would need - i calculated based on automotive paint, not thick industrial paint
11:53 AM roycroft: i'll get my lathe stand finished today, but not the chip tray or top
12:00 PM gregcnc: i approve https://youtu.be/mkv9TALqJ6k?t=3m9s
12:19 PM * JT-Shop looks for a photo of the lathe project when he gets up from his nap
12:24 PM IchGucksLive: hi
12:24 PM IchGucksLive: malcom2073: ;-)
12:42 PM Crom: broke a brush putting new brushing into my spindle grrr
12:49 PM IchGucksLive: Crom: sometimes ir is a miss but it is also a need
12:49 PM IchGucksLive: i did get a full 10 pice packet for my BOSCH 500V
12:50 PM IchGucksLive: and then it broke the Stator
12:50 PM Crom: time to order another set of brushes and back plate.
12:52 PM SpeedEvil: Pack of big brushes you can file to shape is nice
01:00 PM Jymmm: 3 for $0.99 I know if doesn't mean THOSE kind of brushes)
01:01 PM Jymmm: s/if/he/
01:05 PM SpeedEvil: http://www.ebay.co.uk/itm/50Pcs-Graphite-Carbon-Brushes-6-x-7-5-x-18-6mm-for-Electric-Motor-/121767980207?hash=item1c59efecaf:g:DGsAAOSw3v5YuBBI
01:15 PM IchGucksLive: im off For Today have a Nice Day
02:53 PM XXCoder: Crom: dang what happened?
02:58 PM XXCoder: SpeedEvil: interesting
02:59 PM XXCoder: I wonder which would fit my 52mm diamter chinese spindle
03:45 PM Crom: not sure... I haven't taken it apart again yet
03:45 PM XXCoder: oh yeah what npn sensor did you use?
03:45 PM XXCoder: mine seem limited to 300Hz
03:46 PM SpeedEvil: XXCoder: I mean keep in stock a largish brush type or two that won't fit, but can be cut down
03:47 PM XXCoder: one you linked to is pretty decent deal I think. since brushings seem to last only 60 hours or so
03:52 PM zeeshan: gregcnc: lathe had to be scraped
03:52 PM zeeshan: it sank my whole garage
03:52 PM zeeshan: :-)
03:52 PM zeeshan: jk
03:52 PM XXCoder: zeeshan: fuck you.
03:52 PM XXCoder: lol
03:52 PM zeeshan: rofl
03:52 PM zeeshan: maybe this winter
03:52 PM zeeshan: ill work on it
03:52 PM zeeshan: projects are dwindling down
03:53 PM XXCoder: work is kinda slow now too
03:53 PM XXCoder: I mostly work on covers, since theres 3,000 parts to go and my best speed I make 26
03:53 PM XXCoder: in 10 hours
03:53 PM zeeshan: covers?
03:54 PM XXCoder: yeah dunno its curve thingy with tab one end and 2 screw holes on other
03:54 PM XXCoder: some sort of belt thing cover
03:54 PM XXCoder: like car belt but for planes so on
03:56 PM gregcnc: lathe isn't at the top of the project list?
03:56 PM zeeshan: hell no!
03:56 PM zeeshan: :)
03:56 PM gregcnc: getting the bumper out of your living room?
03:56 PM zeeshan: almost
03:56 PM zeeshan: waiting for friend to come over
03:56 PM zeeshan: to help me lif tit
03:56 PM zeeshan: its about 160lb
03:57 PM zeeshan: gregcnc: hows your life goin
03:57 PM zeeshan: any projects on the go?
03:58 PM gregcnc: I had a very frustrating week with my lathe, but I think it's back to normal now
04:00 PM zeeshan: gregcnc: you have 6306 followers?!?!!
04:00 PM zeeshan: you popular guy!
04:00 PM gregcnc: meh
04:00 PM gregcnc: i need to make more videos
04:00 PM zeeshan: youre raping that hardened steel
04:01 PM XXCoder: honestly best way is just do stuff and upload decent (and captioned hopefully!) videos
04:01 PM XXCoder: and if people is interested they are interested.
04:01 PM zeeshan: is that a cbn insert
04:01 PM gregcnc: yeah your comments about captions made me think about it and i will caption future videos
04:01 PM XXCoder: did I miss a video link?
04:01 PM Crom: yep broke brush in half
04:02 PM zeeshan: what kind of doc
04:02 PM XXCoder: ow
04:02 PM XXCoder: isnt sparky show mean its being cut too fast?
04:02 PM zeeshan: no
04:03 PM zeeshan: hardened stuff you gotta melt it
04:03 PM zeeshan: to get the chip to shear
04:03 PM zeeshan: off
04:03 PM gregcnc: CBN, tiny ap=0.1mm it was inthe middle of the insert spec for surface speed
04:03 PM XXCoder: ahh hardened
04:03 PM Crom: hall effect sensor search NJK-5002C Hall Effect Sensor Proximity Switch NPN 3-Wires Normally Open
04:03 PM zeeshan: i like how it's so soft
04:04 PM zeeshan: after the threads are gone
04:04 PM XXCoder: crom you use 2 magnets on oppositing ends
04:04 PM Crom: yep
04:04 PM Crom: they have to be facing the right way though
04:04 PM XXCoder: interesting. did your led display go weird since it expects 1 magnet only?
04:05 PM XXCoder: interesting. sparky then suddely normal steel cutting
04:05 PM gregcnc: It didn't cut all the way through the case at the root, killed a couple threading inserts
04:05 PM Crom: no I always had it configured to use 3
04:05 PM XXCoder: led display is configurable?
04:06 PM zeeshan: only 2 machining videos
04:06 PM zeeshan: :-(
04:06 PM XXCoder: Crom: Switching frequency: 320 KHZ that is pretty fast
04:07 PM gregcnc: I want to do more machining, but projects. thinking about a small engine build series
04:07 PM Crom: it was working fine at 36khz 12000rpm
04:08 PM XXCoder: 12k rpm 3 magnets is 600Hx
04:08 PM XXCoder: Hz
04:10 PM Crom: yep... 600hz
04:11 PM XXCoder: http://www.ebay.com/itm/New-Blue-LED-Tachometer-RPM-Speed-Meter-Hall-Proximity-Switch-Sensor-NPN-/231637326487 this is mine
04:11 PM XXCoder: Response frequency:100HZ
04:11 PM XXCoder: no wonder it didnt work
04:12 PM XXCoder: I need 400 Hz
04:14 PM Crom: got an arduino uno?
04:14 PM XXCoder: nah
04:14 PM XXCoder: already ordered one that can work up to 1000Hz
04:14 PM Crom: I need to get another... but I need to wait for next payday
04:15 PM XXCoder: gregcnc: triangle end?
04:15 PM gregcnc: polygon
04:15 PM XXCoder: well yeah lol but not sure why lol
04:16 PM XXCoder: well nice video
04:16 PM gregcnc: polygon spine to engage another component instead of a shaft coupling
04:16 PM gregcnc: spline
04:17 PM XXCoder: watching mill one. nice glass top
04:18 PM gregcnc: the 125?
04:18 PM XXCoder: yeah
04:19 PM XXCoder: the bearing or pipe cover?
04:19 PM XXCoder: whoo[s
04:19 PM XXCoder: *whoops
04:20 PM XXCoder: not bad
04:22 PM gregcnc: It's a decent machine for what it is
04:22 PM gregcnc: I have parts that use all 10 tools
04:22 PM XXCoder: some people expect too much
04:24 PM gregcnc: 600W on the spindle. if it wasn't a stepper machine, the finishes would be perfect. Tempted to convert to servo and LinuxCNC, but it runs fine
04:25 PM XXCoder: mine is 400w heh
04:25 PM XXCoder: smallish cnc router
04:26 PM XXCoder: https://www.youtube.com/watch?v=xF8erDoJlsY
04:26 PM XXCoder: sorry about shaky parts
04:28 PM XXCoder: that one I forgot to set rapid back to 100% it was still at 10% so it was so slow. :P
04:31 PM gregcnc: i've watched some of your stuff. I watched a whole part run at 50% onthe lathe yesterday and didn't realize it until the end.
04:32 PM XXCoder: well one good thing about 10%
04:32 PM XXCoder: it made that rapid to 0,0 far less scary :P
04:32 PM XXCoder: I dont know why estlcam likes to move tool to 0,0
04:33 PM XXCoder: orginally it stopped z at 5mm and I figured it would hit clamp
04:33 PM XXCoder: so i rose it to 10mm. should be 15mm, less scary! lol
04:33 PM gregcnc: can you change the post? some CAM are set to go to reference position
04:34 PM XXCoder: yeah can just edit gcode too. though estlcam i dont know if it has pre- and post-gcode setups
04:35 PM gregcnc: CAM often has a tool change position and that is usually home/reference
04:36 PM gregcnc: that emco mill looks like this. I don't have a pic of mine anywhere http://www.machinetoolsalesonline.com/auctioninfo.asp?auction=370
04:37 PM XXCoder: funny that machine I currently use a lot at work is even smaller
04:37 PM XXCoder: but similiar in workspace
04:37 PM XXCoder: its haas office mill
04:37 PM XXCoder: trust me, you DO NOT want it in your office. its... very messy
04:37 PM XXCoder: it makes more mess than entire large shop worth of machine does.
04:38 PM gregcnc: the cabinet is huge, id' rather has the 105, identical, but the control is not integral to the base
04:38 PM XXCoder: https://www.youtube.com/watch?v=feNyf6JHzNA
04:38 PM Loetmichel: XXCoder: wimp
04:38 PM XXCoder: sure it looks nice and shiny... for now
04:39 PM XXCoder: it should do small waste operations like engrave, so on. not make part from block/ too much chips for it to handle
04:39 PM Loetmichel: cant count how many times i looked like this: http://www.cyrom.org/palbum/main.php?g2_itemId=5077
04:39 PM XXCoder: look at video, it has drawer for chips
04:39 PM XXCoder: it sucks
04:40 PM XXCoder: lol loet
04:40 PM Loetmichel: or the machine like this: http://www.cyrom.org/palbum/main.php?g2_itemId=13888
04:40 PM Loetmichel: instead of this: http://www.cyrom.org/palbum/main.php?g2_itemId=13891
04:40 PM XXCoder: aww it snowed in machine
04:41 PM gregcnc: I'd like an officemill, they call them CM-1 Compact Mill now, but I'd have to get some real work to buy one
04:41 PM XXCoder: yeah its 50,000 bucks I think
04:41 PM XXCoder: its decent dont get me wrong
04:41 PM XXCoder: just that how it handles chips really suck
04:41 PM XXCoder: also dont spray chips towards tool corsel I had to clean all tools each damned time
04:42 PM gregcnc: that's no good
04:42 PM Deejay: gn8
04:43 PM XXCoder: loet I heard of using deionizer air spray to kill cling
04:43 PM gregcnc: use hoover to suck it before ti clings
04:43 PM Loetmichel: [23:12] <Loetmichel> XXCoder: PMMA and PU chips are the worst
04:43 PM Loetmichel: [23:12] <Loetmichel> clingy as hell and fly like dandelion seeds
04:46 PM XXCoder: yeah maybe deionizer would kill that
04:50 PM Loetmichel: maybe
04:50 PM Loetmichel: it clings to ANYTHING tho
04:50 PM Loetmichel: but thats whats shopvacs are for ;)
04:50 PM XXCoder: yeah though deionizer kills any surface charge so it cant cling to it
04:50 PM XXCoder: its opposite of charging ballon to stick to walls
04:51 PM Loetmichel: CNC 6040 can do that as well... but POM is a less clingy stuff: http://www.cyrom.org/palbum/main.php?g2_itemId=16432&g2_imageViewsIndex=1
04:52 PM Loetmichel: ... especially if you spray it with soap water every now and then
04:52 PM XXCoder: fancy
04:52 PM XXCoder: any advice on cutting arylic?
04:52 PM XXCoder: I have few sheets I plan to try engrave inverse images to
04:52 PM Loetmichel: get a SHARP tool, one lip or 2 flute, never used before. generous feedrate
04:53 PM Loetmichel: and if possible some soap water to cool/lubricate
04:53 PM Loetmichel: NO alcohol of any kind with PMMA!
04:53 PM Loetmichel: and if you can: get cast sheets, not extruded ones
04:54 PM Loetmichel: (Plexiglas (r) GS, not XT)
04:54 PM XXCoder: theres that much difference?
04:54 PM Loetmichel: worlds
04:54 PM Loetmichel: GS works like cast aluminium, XT like AL99,9
04:55 PM gregcnc: speaking of alcohol https://www.instagram.com/p/BTuX122FaVw/
04:55 PM Loetmichel: even tho its chemically identical
04:55 PM XXCoder: lol greg
04:55 PM Loetmichel: harhar, greg
04:55 PM XXCoder: try that to police when drinking and driving :P
04:56 PM Loetmichel: IIRC: root beer has no alc, has it?
04:56 PM XXCoder: "but sir I poured root beer in this square cup and..."
04:56 PM gregcnc: http://smalltownbrewery.com/our-beers/nyfrb/
04:57 PM TurBoss: Hello
05:00 PM roycroft: fermented root beer has alcohol in it, but generally 1.2% abv or less
05:00 PM roycroft: artificial root beer generally does not have any alcohol in it at all
05:01 PM roycroft: we have this new fad in the us called "hard root beer"
05:01 PM roycroft: which is artifically made root beer with grain alcohol added to about 3.5%-5% abv
05:01 PM roycroft: it's mostly shite
05:04 PM Loetmichel: and thats "hard"?
05:04 PM XXCoder: yeah
05:04 PM XXCoder: its far harder than your average root beer with 0%
05:05 PM Loetmichel: <. had beer with 11%ABV
05:05 PM Loetmichel: EKU 28 ;)
05:05 PM Loetmichel: and whole crates of it...
05:05 PM Loetmichel: ...benefits of living in germany
05:05 PM Loetmichel: ;)
05:06 PM Loetmichel: IIRC "standard" beer here has around 6%ABV
05:06 PM Loetmichel: ... and you can buy that legally here at age 16
05:06 PM Loetmichel: ;)
05:06 PM XXCoder: meh
05:07 PM XXCoder: im 41 I dont plan to drink anytime soon
05:08 PM Crom: roycroft: all the hard root beers are crap... Geuine hard root beer is hard to find outside a real brewery
05:08 PM Loetmichel: i am even older. and though i have reduced my alcohol intake significantly from where it was when i was in the "Trinksportverein "gambrinus" e.V" in my younger years i still like the occasional "after work beer"
05:09 PM Crom: I've had 1 shot of brandy in the last 6 years....
05:09 PM Crom: a couple sips of my wife wine otherwise... that it
05:10 PM Loetmichel: <- also likes a decent glass of whiskey every now and then.
05:10 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=15469&g2_imageViewsIndex=1 :-)
05:11 PM Loetmichel: but the times when i got wasted on a weekly basis are definedly gone
05:11 PM Loetmichel: no need to do that any more.
05:24 PM XXCoder: I have enough problems I dont need to add any lol
05:44 PM Crom: just broke my m4 tap
05:46 PM XXCoder: "people who lead good lives dont have pre-existing conditions"
05:46 PM XXCoder: wtf
05:47 PM XXCoder: what did I do before I was even born to have pre-existing condition of being deaf
05:48 PM malcom2073: XXCoder: Your father watched too much footbal. FOOTBALL IS THE DEVIL
05:48 PM XXCoder: lol. my father was deaf also :P
05:49 PM XXCoder: though by mengitis as it was 1930s
05:49 PM malcom2073: Mengitis is brought on by too much football!
05:49 PM XXCoder: :P
05:50 PM * Jymmm tosses some black plague to XXCoder for extra flavor.
05:50 PM XXCoder: lol
05:52 PM malcom2073: I need to clean off my mill, and clean it up so I can use it again
05:52 PM malcom2073: need to re-package the PC in a real enclosure and tidy up wiring
05:53 PM malcom2073: My dad has discovered some $100 DC servo drivers which take step/direction. He's trying them out and if they work I may convert my mill back to servos
05:54 PM gregcnc: Geckos?
05:54 PM malcom2073: nah, some turkish company
05:54 PM malcom2073: Thesea re big drives
05:54 PM gregcnc: oh how big?
05:54 PM malcom2073: 140V 20 amp or something
05:56 PM malcom2073: hmm maybe 10amp, I forget
05:56 PM malcom2073: they're big enough to run my mill though
06:40 PM SpeedEvil: neat
06:41 PM Crom: hmmm finding some PNP NO hall effect switches... M12 that would work better for linuxcnc... then I don't need a 2n2222 transistor I just wire the BOB pin x to black and blue to common ground and brown to 9v
06:42 PM XXCoder: Crom: I found hall sensor that works at 1 KHz and yes it works at 5v
06:42 PM XXCoder: surpising.
06:43 PM XXCoder: its found only ay ebay.
06:43 PM Crom: my home hall effect is at 5v, the rpm is at 8v
06:43 PM XXCoder: LOL! http://www.ebay.com/cln/georgenge-0/arduino/379504426016
06:43 PM XXCoder: huge steppers
06:43 PM XXCoder: can barely fit 20 on one hand
06:44 PM XXCoder: anyway
06:44 PM XXCoder: http://www.ebay.com/itm/401227191004 this one, crom.
06:46 PM Crom: those little floppy steppers... be good for trim tabs
06:46 PM XXCoder: trim tabs?
06:48 PM Crom: on a wing, on the elevator, there are trim tabs from trimming the elevator basically an elevator on the elevator
06:48 PM XXCoder: 1got video or picture example?
06:49 PM * Jymmm sends Crom on an elevator on an elevator to hell - ONE WAY
06:49 PM Jymmm: XXCoder: It's the things that move on the wing of an airplane
06:50 PM Jymmm: XXCoder: https://upload.wikimedia.org/wikipedia/commons/thumb/e/e7/Light_aircraft_elevator_and_trim_tab.JPG/220px-Light_aircraft_elevator_and_trim_tab.JPG
06:50 PM XXCoder: I know what those are but just unsure about trim tabs. I guess coverings that move with elevator on wing
06:50 PM Crom: https://www.google.com/search?site=imghp&tbm=isch&source=hp&biw=1680&bih=905&q=trim+tabs+for+aircraft&oq=trim+tabs+for+aircraft&gs_l=img.3...611.11285.0.12012.

06:51 PM XXCoder: ahh
06:51 PM XXCoder: those steppers are indeed small enough for model trim tabs
06:51 PM Jymmm: XXCoder: Like I said... It's the things that move on the wing of an airplane
06:52 PM XXCoder: yeah but larger planes also have covers that move with elevator
06:52 PM XXCoder: in order to cover gap between wing and elevators
06:52 PM Jymmm: XXCoder: you just never *** LISTEN *** do you ?!
06:52 PM XXCoder: of course not im deaf :P
06:52 PM XXCoder: so those count also?
06:53 PM Jymmm: XXCoder: DUH!
06:53 PM Jymmm: XXCoder: and I think dumb too (or at least thick headed ;)
06:53 PM XXCoder: lol
06:53 PM XXCoder: deaf and dumb now thats classic insult :P
06:53 PM XXCoder: yer a old man
06:53 PM Jymmm: XXCoder: old skool baby, old skool
06:54 PM XXCoder: lol
06:59 PM gregcnc: the kids want me to make them spinners, it's all the rage at school i guess
07:00 PM XXCoder: yeah
07:00 PM XXCoder: some schools is banning em
07:04 PM Jymmm: spinners?
07:04 PM XXCoder: yep
07:04 PM XXCoder: https://www.youtube.com/watch?v=13jScMXI8bg
07:08 PM XXCoder: https://www.youtube.com/watch?v=mP-tqMKqDAQ lol
07:15 PM Jymmm: He needs a bigger compressor tank =)
07:15 PM XXCoder: https://www.youtube.com/watch?v=_dsOHbRlfvM another fun on by him
07:16 PM Jymmm: XXCoder: Well fuck, I've had about 100 brand new ABEC7 skate bearings for a long time.
07:23 PM Jymmm: XXCoder: Not sure what the deal with spinners are, that's what boobs are for
07:23 PM XXCoder: well less aviliable at schools lol
07:24 PM Jymmm: XXCoder: eh
07:24 PM XXCoder: its getting popular in schools
07:24 PM Jymmm: boobs have ALWAYS been popular
07:25 PM Jymmm: https://www.youtube.com/watch?v=c-WKVab6tRY
07:25 PM XXCoder: not surpised as people who isnt interested in those gets bred out
07:26 PM XXCoder: lol thats pretty cool
07:53 PM Crom: just set the AL piece with the brocken tap in hot water and alum...
07:54 PM XXCoder: no dry ice?
07:56 PM gregcnc: every instagram machinist is making spinners
07:57 PM Crom: I have alum and hot water... not dry ice
07:58 PM XXCoder: I was wondering about chilling tap with dry ice
07:58 PM XXCoder: and warming alum
08:02 PM Crom: it's already bubbling
08:35 PM Crom: The VA web site I use says my aug19 and jan04 claims are denied... the bastards
08:36 PM malcom2073: Your conditions must have existed before those dates.
08:37 PM XXCoder: Va suck from what I hear
08:37 PM malcom2073: Pre-existing!
08:37 PM XXCoder: one group keep trying to improve that but other group is refusing
08:38 PM Crom: VA is's bit different.. if you condition exist from time in service they count... if they think they start for a reason after service they deny.... I sent in letters about my remand (sent back for yet another do over) and that evidently didn't help....
08:39 PM Crom: I specifically told them the gout was related to my remand and lead exposure.
08:39 PM XXCoder: bullet formed lead?
08:40 PM Crom: lead from splatted bullets on the armour plate back stop
08:41 PM XXCoder: sucks
10:31 PM Gene_home: was going to download fusion 360 and upgrade since not using for commercial etc. any recommendations on starting this effort?
10:38 PM Crom: Started the fireplace tonight... mostly cardboard, pine, mail, and some oak
10:38 PM Crom: Gene_home: a faster than fast machine
10:39 PM XXCoder: Gene_home: with very good video card
10:40 PM Crom: more memory the better
10:40 PM XXCoder: the more the better
10:40 PM Crom: stand alone video.. not integrated video
10:43 PM Gene_home: what do you recommend, I want to machine a tapered hole for kitchen sink drain for a cnc collant tray. what do you recommend since I am new to this applicatoin
10:43 PM Gene_home: I have a good system, just installed fusion 360 now, it is running, I am looking at full activation now
10:46 PM LeelooMinai: Gene_home: If you are using Fusion non-commercially, what do you want to upgrade to?
10:46 PM Gene_home: I have upgraded past the 30 day trial now. This is all new to me... so am asking questions.
10:47 PM Gene_home: should I create my tapered sink drain hole is solidworks, or can I do this in fusion 360?
10:48 PM LeelooMinai: It's free basically with full features, unless you have a business with some substantial income. So, you just run it in non-commercial mode, and yes, you can do quite advanced things, including CAD + CAM.
10:49 PM LeelooMinai: It's 3D CAM + CAM + simulations, g-code export, and other in one package basically.
10:49 PM Gene_home: leelooMinai: Thanks!
10:49 PM LeelooMinai: 3D CAD + CAM *
10:50 PM XXCoder: if youre curious, company max income for free is 100,000. thats income not profit
10:53 PM Crom: I want.... no money... https://www.newegg.com/Product/Product.aspx?Item=N82E16819117726
10:54 PM Crom: 4.2Ghz quad core 91w i7-7700
11:01 PM SpeedEvil: When you don't want to typo your g-code. https://futurism.com/this-robot-completes-2-hour-brain-surgery-procedure-just-25-minutes/
11:02 PM Crom: though finding a mini-itx <B for that will be fun
11:03 PM XXCoder: SpeedEvil: and you REALLY want to dry run code first
11:04 PM LeelooMinai: Crom: Few weeks ago I bouight from some guy locally a PC for $250 (CAD), so sub $200 US that had inside some older i7 + 8GB ram + tiny Intel motherboard and nice Antec PSU.
11:05 PM LeelooMinai: Rapid 10cm in X by accident - bad.
11:08 PM Crom: nice
11:11 PM Crom: oooops kinda hard to home Z when it's taken apart
