12:16 AM pink_vampire: i made brass washer
12:19 AM pink_vampire: https://i.imgur.com/GVWez22.jpg
12:19 AM pink_vampire: https://i.imgur.com/MmhqM9t.jpg
12:20 AM Wolf__: you need a lathe in your life =P
12:20 AM pink_vampire: no for that
12:21 AM pink_vampire: watch that
12:21 AM pink_vampire: https://i.imgur.com/sPjtlUI.jpg
12:22 AM Wolf__: 0.o
12:23 AM pink_vampire: just adding a valve.....
12:24 AM Wolf__: I see that =)
12:24 AM Wolf__: still think lathe would have made a prettier part
12:24 AM pink_vampire: just give misttttttttttttttttttttt
12:24 AM pink_vampire: lol
12:24 AM Wolf__: lol
12:25 AM pink_vampire: my soldering iron is basically metal glue gun
12:26 AM Wolf__: mig welder is a metal glue gun imo
12:28 AM pink_vampire: you can't take it a part with just heat
12:28 AM Wolf__: plasma cutter
12:29 AM Wolf__: or gas axe (oxygen/acetylene cutting torch)
12:30 AM pink_vampire: makeup remover also clean metal..
12:30 AM Wolf__: lol
12:32 AM pink_vampire: also smell good
12:33 AM Wolf__: haha
12:35 AM pink_vampire: eyeliner is almost as good as dykem
12:35 AM Wolf__: haven’t tried it
12:36 AM Wolf__: blue sharpie works good
12:37 AM pink_vampire: https://www.ulta.com/telescopic-precision-waterproof-liquid-eyeliner?productId=xlsImpprod560126&sku=2218711&cmpid=PS_Non!google!Product_Listing_Ads&cagpspn=pla&CATCI=pla-195005500830&CAAGID=35321891920&CAWELAID=772017736&catargetid=330000200000806033&cadevice=c&gclid=EAIaIQobChMI7JPYgY2E2QIVSrjACh1u2QFpEAQYAiABEgJiTPD_BwE
12:38 AM Wolf__: I’ll stick with the markers
12:40 AM pink_vampire: i love the dry erase for temporary stuff
12:49 AM pink_vampire: soldering is done
12:53 AM Wolf__: =]
01:02 AM pink_vampire: success!
01:03 AM pink_vampire: the valve work better then the needle in the flow meter
01:03 AM pink_vampire: and i saw what you mean about the tube at the end
01:04 AM * Wolf__ knows things...
01:04 AM Wolf__: not many but some… lol
01:04 AM Wolf__: =) needle valve should help with the coolant flow
01:05 AM pink_vampire: Wolf__: is awesome
01:07 AM pink_vampire: somewhere here there is a piece of tube...
01:08 AM pink_vampire: find it!
01:08 AM pink_vampire: Wolf__: what length do you think will be good?
01:09 AM Wolf__: about ————————————————————————— maybe?
01:10 AM pink_vampire: mmm let me see
01:10 AM Wolf__: 100mm
01:11 AM pink_vampire: https://i.imgur.com/osAtrC4.jpg
01:11 AM Wolf__: lol
01:13 AM * gloops hopes to be reporting success later
01:13 AM pink_vampire: the line is 60 mm
01:13 AM Wolf__: 105mm on my screen
01:14 AM pink_vampire: this is veryyy old screen
01:14 AM pink_vampire: maybe 15"
01:15 AM Wolf__: 27” wide monitor
01:17 AM pink_vampire: it is 3.5mm inner diameter
01:17 AM pink_vampire: to make it smaller?
01:18 AM pink_vampire: i mean the tip
01:19 AM Wolf__: 3.5mm might work ok
01:20 AM MrHindsight: Wolf__: either your conversation is with someone I have on ignore or you're having and episode :)
01:21 AM * gloops reads homing again
01:22 AM gloops: in fact ill have another coffee first
01:23 AM pink_vampire: MrHindsight: are you ignore me??
01:24 AM gloops: at 200 ipm on 1100x900 job, 1/16 stepover, it would take 144 minutes to mill the surface, 1 pass
01:26 AM pink_vampire: wowww
01:26 AM gloops: thats why speed is important for large format routers
01:27 AM pink_vampire: 1100" x 900"??
01:27 AM gloops: that isnt even large format, medium probably
01:27 AM gloops: no mm
01:27 AM Wolf__: MrHindsight: ya have pink_vampire on ignore?
01:28 AM pink_vampire: what is the size of the end mill?
01:28 AM gloops: pink_vampire its just an imaginary job, was just playing with some figures
01:29 AM gloops: i am hoping to work on sheets that size though
01:29 AM pink_vampire: gloops: 200ipm is 5m/m
01:29 AM gloops: yes
01:29 AM pink_vampire: this is veryyy fast machine
01:29 AM gloops: thats what my y is doing
01:29 AM gloops: lol it isnt fast all
01:30 AM pink_vampire: for cutting metal??????
01:30 AM pink_vampire: this is crazyyy fast
01:30 AM gloops: double that would be quick, 3 times youre getting to good speed
01:30 AM gloops: no wood lol
01:30 AM pink_vampire: hooo ok..
01:30 AM gloops: it would cut ally that quick maybe
01:34 AM pink_vampire: use large end mill
01:37 AM Wolf__: more horse power and a huge fly cutter imo =P (too bad that wouldnt actually work on wood probably)
01:38 AM gloops: you can get inch size end mills for wood, just under half inch pass, but thats for surfacing, for pocketting or whatever its still a long way round the job with a small cutter
01:39 AM Wolf__: yeah, not to mention most routers are high rpm spindles, usually doesnt work well with large cutters
01:40 AM Wolf__: like trying to spin https://i.imgur.com/hx0vvs6.jpg or these https://i.imgur.com/fy49bwn.jpg lol
01:40 AM gloops: usually have speed control with spindle, ive got 0-24000 on my little one
01:42 AM Wolf__: iirc the face mill is 2.5”
01:43 AM gloops: https://woodworker.com/images/j210/172-442.jpg not sure how big these go, a bit bigger than that, expensive though
01:44 AM gloops: 2 inserts slicing, the other 2 peel the waste off
01:44 AM Wolf__: my shell mills top out at 2”
01:44 AM Wolf__: I think
01:45 AM gloops: you really want horizontal spindle for large surfacing work
01:45 AM Wolf__: well , time for me to get some sleep
01:45 AM gloops: time for me to read heh
01:56 AM gloops: my best plan here is to get homing working on Y axis, before jumping in to the tricky X
01:56 AM gloops: as have never fitted/configed a home switch before
01:59 AM Deejay: moin
02:02 AM gloops: howdy
02:12 AM pink_vampire: Wolf__:
02:13 AM pink_vampire: any idea why i get this drop? https://i.imgur.com/obodCOj.jpg
02:15 AM gloops: so, 2 joints on 1 axis, if i want them to home together, i use same HOME_SEQUENCE number say i have X and XA joints, X =1 XA =1
02:16 AM gloops: they will need seperately wired switches, not in a chain, as if they were on a chain, one would break the signal before the other and stop the sequence
02:16 AM jesseg: pink_vampire, I'm not sure I understand the significance of the question or the drop...
02:16 AM pink_vampire: i disable my limit swithes
02:17 AM gloops: in the case of 2 or more joints per axis, homing must be enabled
02:17 AM pink_vampire: jesseg: the point is to brake the drop to several small droplets with the lowest pressure
02:18 AM jesseg: pink_vampire, is that blurry black thing your misting nozzle?
02:18 AM pink_vampire: yes
02:18 AM gloops: ive studied this and had it all my mind several times over the last months, when it comes to do it i cant remember any of it
02:18 AM pink_vampire: just a 1/8" pipe
02:19 AM jesseg: pink_vampire, well I'm afraid that oil tends to form drops as soon as there is not a force preventing it...
02:20 AM jesseg: Misters usually work by shooting a high speed jet of air through the nozzle right where it sucks in the oil, and the high velocity air breaks the oil into fine droplets..
02:21 AM jesseg: If that is then put into larger tube where the airspeed reduces, the oil mist will hit the walls and turn back into just liquied oil running down...
02:22 AM pink_vampire: i don't want to make fog
02:22 AM pink_vampire: just very small drops
02:26 AM jesseg: you could generally control the size of the drops by the airspeed
02:26 AM jesseg: but the generated air/oil mixture must not be slowed down or it will settle out
02:28 AM archivist: gloops, just wire it and configure, then you will see it in action then it will become obvious how it works
02:29 AM archivist: MrHindsight, search the patent for the head
02:32 AM gloops: i reckon so yeah archivist, i might do the y first though and see how homing with a switch works, and what comes up in the ini file, i think ive pretty much got it worked out
02:33 AM gloops: Y axis is working fine, ive got some sorting out with pins and ini and hal to do for the x though, will take me a while heh, maybe get it done sometime today ive got to go out in a bit
02:38 AM pink_vampire: solved!
02:39 AM pink_vampire: i soldered a small tube to the end
02:43 AM jesseg: good work pink_vampire
02:44 AM gloops: getting 210 ipm on Y, at which point motor screams, the motor pulley is slipping though - only one i didnt put 2 screws in, so maybe get a bit more
02:47 AM pink_vampire: i'm full of baby oil :)
02:52 AM pink_vampire: now i need to re solder it nice
04:06 AM gloops: hmm, searching for home switch, hits switch, switch state changes, but doesnt stop, more playing req
04:17 AM jthornton: morning
04:20 AM gloops: like the pin hasnt been assigned, but it has
04:24 AM jthornton: are you using one switch for both home and limit?
04:35 AM gloops: alls ive done is put a switch on, assigned pin 15 as home, run homing - it searches, trips switch, but just carries on
04:35 AM gloops: multimeter shows a change of v when switch is worked
04:36 AM jthornton: how did you assign pin 15 as home?
04:36 AM gloops: using stepconfig
04:36 AM jthornton: odd for sure
04:37 AM IchGucksLive: hi
04:37 AM gloops: for homing switch i just run one wire to pin 15 and the other to ground right?
04:37 AM gloops: hi Ichs
04:37 AM IchGucksLive: gloops: did you follow the rule not to set HOME Zero
04:37 AM IchGucksLive: set HOMEOFFSET Uero
04:37 AM gloops: ive changed HOME from 0
04:38 AM jthornton: what card?
04:38 AM IchGucksLive: ammd HOME min 5mm to workside
04:38 AM gloops: just a mach 3 breakout board
04:38 AM IchGucksLive: gloops: can you will you upload the gal ini
04:38 AM IchGucksLive: gloops: the 5Axis
04:38 AM gloops: could do but will take a few minutes, cnc computer not online
04:39 AM jthornton: gloops: open up the show hal configuration and see if it toggles in the watch window
04:39 AM IchGucksLive: gloops: THIS
04:39 AM IchGucksLive: https://www.youtube.com/watch?v=_Zvrqgxgt8c
04:39 AM IchGucksLive: did you supply 12V
04:39 AM * jthornton shuts up for a while
04:40 AM IchGucksLive: jthornton: have a nice sleeep :P
04:40 AM gloops: 12v to input pins?
04:40 AM IchGucksLive: no to the BOB
04:41 AM gloops: no - i can
04:41 AM IchGucksLive: the Interface needs 12V to support input
04:41 AM gloops: ahh..
04:41 AM gloops: ok will try that thanks
04:41 AM IchGucksLive: How the Hell do i Videos if People like YOU dont look at it :-(
04:42 AM IchGucksLive: glloo look at the VIDEO
04:42 AM IchGucksLive: dont get 12V to PCconnectors
04:42 AM gloops: lol, im only just started lookin at home switch, i didnt think you needed 12v, the switch is changing from 0-5v
04:43 AM IchGucksLive: '****dont get 12V to PCconnectors****
04:43 AM gloops: right ill watch the vid
04:43 AM gloops: the 12v comes from vfd, its not been switched on
04:43 AM gloops: watching video
04:43 AM IchGucksLive: NO 12V no Input
04:44 AM gloops: right got it! lol
04:44 AM XXCoder: heys
04:44 AM gloops: first think you say on the video heh
04:44 AM gloops: ill go try that
04:46 AM jthornton: morning XXCoder
04:47 AM XXCoder: hows things
04:48 AM jthornton: not bad I guess I'm a few weeks behind on this machine build, Henry is still in the dog house and I'm undecided about his fate
04:50 AM gloops: input bank is now lit with led, but homing still same heh
04:56 AM gloops: https://ibb.co/kq1ur6 ive got that in ini
04:57 AM gloops: jthornton hal conifiguration - thats in the linuxcnc interface right?
05:00 AM jthornton: the configuration files are in linuxcnc/configs/name of your configuration
05:01 AM jthornton: open up the show hal configuration and add that pin to the watch window and then toggle it
05:01 AM gloops: oh yeah the hal file - ill have a look, not used a watch window before
05:02 AM jthornton: you can use paste.ubuntu.com to pastebin the hal and ini files
05:02 AM gloops: will try in a bit, got some other stuff to do at the same time, just having 5 minutes with it when i get chance
05:02 AM jthornton: ok
05:09 AM pink_vampire: https://i.imgur.com/sPjtlUI.jpg
05:10 AM pink_vampire: before^
05:11 AM pink_vampire: https://i.imgur.com/2IafFCt.jpg
05:11 AM pink_vampire: https://i.imgur.com/9MmSYNB.jpg
05:11 AM pink_vampire: after
05:12 AM pink_vampire: XXCoder: ^
05:12 AM XXCoder: hey
05:12 AM XXCoder: looks better designed
05:13 AM XXCoder: but why not whole thing designed and made?
05:13 AM XXCoder: though might need a lathe hmm
05:24 AM gloops: well i dont believe it, switch from pin 15 to pin 13, works fine!
05:24 AM gloops: ive either got a dodgy pin 15 or that pin is integrated into something else on the board
05:24 AM XXCoder: is 15 in or out only and youre using it wrong way?
05:25 AM gloops: its just an input pin, theres a bank of 5 pins all input only
05:25 AM XXCoder: you got a way to "listen" to that pin>?
05:26 AM gloops: alls i changed was the wire from 15 to 13 and ran stepconfig to assign 13
05:26 AM gloops: only a multimeter, it was changing state when switch was worked, halmeter didnt show any change though
05:27 AM XXCoder: odd
05:27 AM gloops: anyway..thats a couple hours gone haha
05:27 AM gloops: i seem to remember pin 15 coming up when i was wiring the spindle last time, im not sure if its integrated with a relay - not bothered atm anyway
05:55 AM Tom_L: you got the free pin bonus too ehh? i had one on my pendant go out
06:06 AM pink_vampire: https://i.imgur.com/zYoCX4e.jpg
06:07 AM XXCoder: looks neater than first version thats for sure
06:10 AM pink_vampire: also much smaller then any commercial available
06:17 AM XXCoder: nice
06:17 AM XXCoder: my machine has nothing :P
06:20 AM gloops: Tom yeah trust me to pick the duff pin to try it out, couple hours head scratching there for nothing lol
06:25 AM gloops: will try x switches next
06:49 AM archivist: gloops, are you using the correct pull up voltage on the inputs
07:02 AM gloops: y home is working fine now archivist, something dodgy with pin 15 was all
07:03 AM gloops: got x switches wired up going to attempt config in a bit, one least read
07:03 AM archivist: if you dont pull up properly you will see that apparent fault
07:04 AM gloops: not sure what you mean by pull up?
07:05 AM archivist: the switch connects via a resistor to +5 or +12 volts depending on the BOB card you are using
07:05 AM phipli: gloops, electrically, it sort of sets a default state for the output
07:06 AM phipli: the output can be forced down, but if there is not clear output it defaults to HIGH
07:06 AM gloops: yeah it does need 12v to use input pins on this board, i was assuming 5v, i tried both and pin 15 didnt work, moved to pin 13 - no problem
07:07 AM phipli: gloops, http://i20.servimg.com/u/f20/11/80/59/89/open_c10.png
07:09 AM enleth: gloops: how exactly do you connect the switch to the pin?
07:09 AM gloops: hmm, going over my head really, i am not very knowledgable with electricity, mainly relying on following basic tutorials, it is working though, so long as i copy the way ive done y i should be ok for the others
07:09 AM gloops: enleth wire into bob pin
07:10 AM phipli: sorry gloops - thought you were using outputs for some reason - https://cdn.sparkfun.com/assets/6/f/b/c/7/511568b6ce395f1b40000000.jpg
07:10 AM enleth: with a miswired/absent pullup or pulldown, it's possible that one input opto might be triggering by accident because it was created a bit more sensitive due to production inaccuracies
07:10 AM phipli: better picture
07:11 AM phipli: yeah, and the faults can be sporadic making it a pain to diagnose
07:11 AM enleth: so perhaps it's still wired wrong but you're lucky
07:11 AM gloops: the pull up must be integrated into the board though?
07:11 AM phipli: more susceptible to noise etc.
07:11 AM phipli: gloops, what board is it? do you have a link?
07:12 AM archivist: on this bob the input is via an opto :)
07:12 AM enleth: gloops: doesn't have to be, gives more flexibility if it isn't
07:12 AM gloops: its the standard 'mach 3' board https://www.youtube.com/watch?v=_Zvrqgxgt8c
07:16 AM phipli: can't find the schematic for it
07:16 AM phipli: but I have one downstairs somewhere
07:17 AM phipli: optos should false trigger too much though unless you have quite a lot of induced current?
08:05 AM IchGucksLive: hi
08:05 AM IchGucksLive: gloops: ?
08:06 AM IchGucksLive: archivist:
08:07 AM archivist: ?
08:07 AM gloops: yes got it working thanks
08:07 AM IchGucksLive: gloops: your BOB has Comen GND so no power at all at the switches
08:08 AM IchGucksLive: archivist the simple BOB is only PIN-> GND sinal
08:08 AM gloops: wouldnt work on pin 15 - works fine on other pins
08:08 AM IchGucksLive: i got all 9 switches to one port Pin10
08:08 AM IchGucksLive: soi i got 3-4 left
08:08 AM IchGucksLive: Plasma THC for instance
08:09 AM gloops: i can do that for the others but not x axis with 2 motors - they have to home together, needs seperate pins
08:09 AM IchGucksLive: wirerd as shown in VID
08:10 AM archivist: videos are terrible for wiring diagrams
08:10 AM gloops: as i read it, home is initiated when pin state changes hi/low or vice versa, just 0 or 5v
08:10 AM gloops: you either let it ground - to 0v
08:11 AM IchGucksLive: ok you nmow now im back to construction BYe later
08:11 AM gloops: or you or you break ground pushing pin to 5v
08:11 AM archivist: the pins "pull up" pulls it high
08:11 AM gloops: cheers
08:11 AM IchGucksLive: it gives nice sparkles like vulcan on silvester if you do wirer wrong
08:11 AM IchGucksLive: but on 5eurios its cool
08:12 AM gloops: its not the 5 euros - its waiting for the post
08:12 AM IchGucksLive: if you brek one you will not make the same fault
08:12 AM gloops: i should have a spare here
08:12 AM IchGucksLive: BYE AND NO Power to the Switches at all withourt relay
08:13 AM IchGucksLive: i got 24V on the switches with relay to BOB
08:13 AM gloops: i think this can do 400ipm ive seen it while messing about, i will sort that another time
08:13 AM IchGucksLive: the standard cinductive
08:14 AM gloops: my head is not in electronics/hal config mode today lol, i feel a bit rough, but will persevere in a bit
08:15 AM archivist: he gives wrong info
08:16 AM gloops: well ive got most info from linuxcnc docs and cncworld - re switches, probably very simplistic way to understand them but thats probably the best for me
08:17 AM gloops: idid this hal config in 20 minutes a couple of months ago, the screen is just a blur today!
08:17 AM archivist: do it a couple more times and it sinks in
08:18 AM gloops: yeah just keep messing about with it, the terms become familiar, starts to sink in
08:18 AM archivist: stepconf holds you back from full understanding
08:18 AM Deejay: re
08:18 AM gloops: the thing is you have to run stepconfig to get the basic files, then you can edit them
08:18 AM Jymmm: the ini (imo) is actualy pretty easy to read/follow
08:18 AM gloops: its a bit of tedious editing though
08:19 AM gloops: only one section left
08:19 AM gloops: the ini is easy, the hal needs more careful placing of joint references, more times
08:46 AM pink_vampire: leak in the oil tank solved!
08:46 AM pink_vampire: the mist system is up and running!!!
08:48 AM archivist: but now the house is all oily :)
08:52 AM pink_vampire: no
08:52 AM pink_vampire: it is baby oil
08:55 AM pink_vampire: the vitamins jar leak from the cap, so i came up with a solution to connect 2 tubs in to the cap of regular 1/2 litter soda bottle. and that hold the pressure with out any issue
09:01 AM pink_vampire: https://i.imgur.com/4EKlgwD.jpg
09:01 AM pink_vampire: https://i.imgur.com/4deszAx.jpg
09:02 AM pink_vampire: archivist: ^
09:03 AM archivist: I expect an exploding bottle video later
09:03 AM pink_vampire: from 20 psi MAX?
09:03 AM gregcnc_: plastic soda bottles take serious pressure
09:04 AM pink_vampire: according to stuff on youtube they give up at about 150psi. my compressor go up to 125psi...
09:05 AM pink_vampire: also the plastic tube is rated to 55psi
09:05 AM archivist: a safe working limit is around 85PSI
09:06 AM phipli: any suggestions for a good place to get your first manufactured PCBs made?
09:06 AM pink_vampire: for what?
09:06 AM phipli: pink_vampire, aimed at me, or archivist
09:06 AM phipli: ?
09:06 AM archivist: china
09:06 AM pink_vampire: phipli: some place IN the us
09:06 AM phipli: pink_vampire, efforts - I'm not in the US
09:06 AM pink_vampire: mmm
09:06 AM archivist: I used to get pcb's uk made
09:06 AM pink_vampire: try to avoid china
09:07 AM phipli: Something like Seeed stuido?
09:07 AM archivist: most have shut down
09:07 AM JT-Shop: phipli: Tom_L gets pcb's made in china IIRC
09:07 AM phipli: probably a little more tolerant of crap / stupidity as they deal with beginners?
09:08 AM phipli: fritzing links to some company in Europe somewhere
09:08 AM pink_vampire: i make my pcbs local
09:08 AM phipli: I think my brother has used them, but they were quite a bit more costly than good chinese companies
09:09 AM phipli: pink_vampire, for work or home?
09:12 AM archivist: uk makers usually charged a premium for the setup, which the chinese seem to swallow
09:12 AM pink_vampire: home
09:15 AM JT-Shop: phipli: got the rpi zero and could not get the wifi to work headless and now I'm waiting on a mini HDMI to standard HDMI adapter lol
09:16 AM phipli: JT-Shop, interesting
09:16 AM phipli: did you use recent instructions?
09:16 AM phipli: used to be done differently on older versions of Raspbian
09:16 AM JT-Shop: I think so, gotta run to town be back in a bit
09:17 AM phipli: archivist, seeedstudio say $4.90 for 10x boards
09:17 AM phipli: that is... quite cheap
09:17 AM JT-Shop: yea I've started to use the date function on google
09:17 AM phipli: archivist : postage must be extra otherwise it doesn't make sense
09:18 AM archivist: seed and similar are very cheap
09:20 AM phipli: cheap enough for mistakes :)
09:20 AM phipli: (I'm not that confident in myself - I've breadboarded the circuit from the schematic, but... don't trust myself)
09:20 AM archivist: we used to have to pay £100 ish just as a setup charge for prototypes
09:20 AM phipli: I've seen a UK firm that does a free prototype
09:21 AM archivist: some do now to compete with china
09:21 AM phipli: but I'm not a bastard / I assume there is a catch
09:22 AM archivist: I assume mistakes in the first run :)
09:29 AM archivist: if it is only 2 layer you can bodge it later :)
09:44 AM phipli: archivist, yup - bodge to working, then order more
09:44 AM phipli: hum
09:45 AM phipli: they advise you use a gerber viewer to check the files
09:45 AM archivist: yup
09:45 AM phipli: when I do, my drill file doesn't align with everything else
09:45 AM phipli: what am I doing wrong.....
09:45 AM archivist: origin?
09:46 AM phipli: units?
09:46 AM phipli: perhaps one is in inches, one in metric?
09:47 AM archivist: I wrote a gerber viewer for a giggle once upon a time
09:47 AM phipli: they both look like they're in mm
09:48 AM phipli: can't be just origin because the scale looks wrong too
09:48 AM archivist: has one not set the units?
09:49 AM phipli: I'll try resetting both units
09:49 AM phipli: in case something has glitched
09:49 AM archivist: integers without decimal point so number of places can affect scale
09:52 AM roycroft: "integers without decimal points" sounds like an international maths relief organisation
09:55 AM phipli: along with divisions without remainders?
09:57 AM archivist: a gerber line 2745 X57500Y-57000D01* has no . so the number of places needs to be stated in the prolog
10:00 AM phipli: grrr
10:00 AM phipli: the drills are fine in gerbview
10:30 AM jesseg: Morning folks
10:34 AM pink_vampire: hi jesseg
11:02 AM skunkworks: https://computers.woot.com/offers/viewsonic-cdp4260-tl-42-fhd-touch-display?ref=w_cnt_wp_0_5
11:03 AM skunkworks: cnc screen?
11:05 AM pink_vampire: look VERY NICE
11:06 AM cradek: about 25" too big
11:17 AM * skunkworks was joking mostly
11:17 AM gloops: well, didnt make any more progress on mine went to bed instead
11:17 AM skunkworks: is a good price for a touch screen that bit
11:17 AM skunkworks: big
11:33 AM phipli: heh. archivist - I just realised something
11:33 AM IchGucksLive: hi
11:33 AM phipli: my board is < 50% the size of their minimum board size
11:34 AM phipli: I could have put two on one "board" and got twice as many
11:34 AM phipli: would have meant the price would have been ~55p / board
11:34 AM * phipli makes note for next time
11:34 AM phipli: afternoon IchGucksLive
11:34 AM IchGucksLive: phipli: with mountinghole space
11:34 AM phipli: mounting holes already included
11:34 AM Rab: phipli, for PCBs? Sometimes fabs will charge extra if they perceive tiling.
11:35 AM phipli: Rab, really? it is no skin off their back if I fit one or two in the same space?
11:35 AM phipli: meh. cheap enough anyway
11:35 AM * phipli exits for dinner
11:36 AM Rab: phipli, you would think so, but of course they tile all the jobs into big panels. So any extra you use (even if it's within the minimum you paid for) hurts their bottom line.
11:38 AM Rab: Many fabs explicitly charge for tiling up front. Not sure what happens if you tile without paying, but since they stated the terms up front I guess it's their option whether to proceed.
11:51 AM phipli: just checked their ts and cs
11:51 AM phipli: looks like they're ok with tiling
11:52 AM phipli: they say "We do not provide panelization services, we will follow the uploaded files directly. If you want the sub-boards to be panalised, you will have to do it yourself"
12:24 PM enleth: Rab: really depends on the fab, many don't give a rat's ass about how you use the space you pay for, the machine is going to spend about the same amount of time making it anyway
12:56 PM gloops: nice 4 axis posted on facebook https://yadi.sk/i/17Ni_sA4ywK9X
12:57 PM gloops: simultaneous 4 axis
12:58 PM gloops: one day!
01:05 PM MrHindsight: heh, scene begins with a mill between a pair of legs
01:05 PM pink_vampire: https://www.youtube.com/watch?v=4OLfAFkL8EY
01:07 PM gregcnc: lunch is too early for the clubs
01:07 PM pink_vampire: here is 2pm
01:08 PM gregcnc: clearly, it's time to party then
01:44 PM fragalot: hey miss0r - has the servo arrived yet?
01:45 PM miss0r: Yep. I have it in my hand right now. It looks nice :]
01:45 PM fragalot: :D
01:46 PM fragalot: was it an analog or digital?
01:46 PM miss0r: I have no idea. I just bought the thing :) I'll look into that now :]
01:48 PM fragalot: not sure if it matters really for what you're doing
01:48 PM miss0r: I guess not. I just need to know how to control it
01:48 PM fragalot: easy
01:48 PM fragalot: :)
01:48 PM Wolf__: servo? like drive servo or RC servo?
01:48 PM fragalot: Wolf__: RC
01:49 PM Wolf__: easy to control
01:49 PM fragalot: continuous rotation version to use as a spindle motor
01:49 PM Wolf__: wait, what
01:49 PM miss0r: ^^
01:49 PM fragalot: :D
01:50 PM fragalot: Wolf__: because they have oodles of torque
01:50 PM Wolf__: rc servo https://i.imgur.com/lwfrFqf.jpg
01:50 PM Wolf__: I think you mean brushless motor with esc?
01:50 PM fragalot: no.
01:51 PM fragalot: servo.
01:52 PM Wolf__: doesnt sound like a radio control hobby servo then
01:52 PM fragalot: it is
01:52 PM miss0r: This one actualy: https://www.ebay.co.uk/itm/Power-HD-Continuous-Rotation-Servo-AR-3606HB-2149/282121726726?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649
01:52 PM miss0r: Excellent for my spindle needs
01:52 PM fragalot: miss0r: have you figured out how to mount it?
01:52 PM miss0r: I think i'll use screws. Not sure thou :P
01:52 PM enleth: is that for drilling pre-heated butter?
01:52 PM Wolf__: what… to move the spindle?
01:53 PM miss0r: Wolf__: For rotating the spindle
01:53 PM Wolf__: thats like maybe 10 rpm
01:53 PM miss0r: enleth: hardened steel
01:53 PM Wolf__: 20?
01:53 PM * fragalot is loving how confused everyone appears to be by this concept
01:53 PM fragalot: Wolf__: plenty!
01:53 PM miss0r: Wolf__: 93 actualy
01:53 PM JT-Shop: Yippie a successful test of the cleaner exit end... only had to design and build 2 too get a really good one
01:54 PM Wolf__: https://i.imgur.com/r2krYgI.jpg is servo =]
01:54 PM fragalot: miss0r: have you installed that scale yet?
01:54 PM fragalot: Wolf__: I love how short the wires are :D
01:54 PM miss0r: fragalot: I've done the foot work now. I have a few drawings of brackets'n mounts I need to CNC
01:54 PM Wolf__: yeah lol
01:55 PM Wolf__: I got it off ebay for low price because of that
01:55 PM miss0r: Also, The machine needed some serious dragchains to get the cables around, So I have to order thoes as well.
01:55 PM fragalot: miss0r: I bet.
01:56 PM fragalot: can the drag chains support themselves over that distance, or will you need support brackets for that too?
01:56 PM miss0r: support brackets, absolutly. But they wanted to make those themselves.
01:57 PM fragalot: in other words, they may not bother?
01:57 PM fragalot: :P
01:57 PM miss0r: I realy would rather have it that way - I would have to go buy it from a 3rd party anyway.
01:57 PM miss0r: No. I think they'll do it
01:57 PM fragalot: Alright
01:57 PM miss0r: Otherwise the installation will fail in a hurry
01:58 PM miss0r: The machine has a 45KW main spindle. That is some serious stuff
01:58 PM fragalot: Beefy.
01:58 PM miss0r: Yeah, They use a 500 shellmill on it alot. And apparently they never even get close to hitting the limit of the spindle
01:59 PM miss0r: You gotta love ol' iron
01:59 PM fragalot: don't let management hear that
02:00 PM miss0r: hehe. He was the one telling me. The manager there likes to get down and dirty. manager = owner. They are only 5 people there. They build and restore thoes shredders they use to.. well shred cars with
02:00 PM fragalot: neat
02:01 PM fragalot: I have an all in one printer/shredder
02:01 PM fragalot: an old black&white lexmark laser printer
02:01 PM fragalot: it shreds half of what it prints
02:01 PM fragalot: doesn't even need manual intervention to do it either
02:01 PM miss0r: Yeah, I had one of thoes too. I had to replace it, as I only bought it as a printer, but it kept doing that other thing to 2/3rds of what I tried to print
02:01 PM miss0r: lol. Looks like we got the same deal :D
02:01 PM fragalot: :D
02:03 PM gloops: nice 4 axis posted on facebook https://yadi.sk/i/17Ni_sA4ywK9X
02:03 PM fragalot: that url smells like cancer
02:04 PM miss0r: nah, thats just me... I had a little too much cheese
02:05 PM gloops: not a description of a url ive seen before lol
02:05 PM gloops: it works ive watched it, hes a regular poster
02:06 PM miss0r: Hmm. Is it possible to have this run in both directions? It seems it has a +, - & PWM
02:06 PM fragalot: miss0r: yes
02:06 PM fragalot: connect + to 5V, - to GND, and 50% PWM = stationary
02:06 PM fragalot: 0% = full reverse, 100% = full forward
02:06 PM miss0r: Ahh, alright.
02:06 PM miss0r: So I could just use this thing as a motor, hooked to 5 volts :D
02:07 PM Wolf__: nope
02:07 PM Wolf__: needs the pwm pluse train to know to turn
02:07 PM miss0r: 0% PWM either means +5 volts or 0volts
02:07 PM Wolf__: no
02:07 PM miss0r: educate me
02:09 PM gloops: https://scontent.fman1-2.fna.fbcdn.net/v/t1.0-9/27544620_10215431985102789_3079863647556524702_n.jpg?oh=0b66d3531ffd0161f6bc1fc983792db7&oe=5ADBFA89
02:09 PM gloops: that is pretty accomplished modelling
02:10 PM MarcelineVQ: imagine having to clean that thing
02:10 PM gloops: Yura Tikhonovskiy < russian name?
02:10 PM gloops: MarcelineVQ when your staircase looks like that you dont worry about cleaning
02:10 PM Wolf__: miss0r: https://electronics.stackexchange.com/questions/129961/how-to-get-the-pwm-frequency-and-duration-of-each-pulse
02:11 PM FinboySlick: My cat's tail would puff up every time he reaches the bottom of the stairs.
02:12 PM gloops: yeah, think id have gone with a mermaid newel column
02:12 PM fragalot: you can just use the servo library from arduino
02:14 PM MrHindsight: fragalot: looks like the rollers just pack the powders and they use some sort of nozzle system to drop the powders, so the pics are bit missleading
02:15 PM miss0r: wolf_ indeed
02:15 PM fragalot: MrHindsight: yeah that's the explanation I got, they wouldn't give out too many details though
02:15 PM MrHindsight: fragalot: that explains the low res
02:15 PM fragalot: MrHindsight: but how are the pictures misleading
02:16 PM MrHindsight: fragalot: that the rollers place the powder, where they just operate like other SLS printers by packing and leveling the powder
02:16 PM MrHindsight: I gave them too much credit
02:16 PM fragalot: they're more about the concept of using 2 materials, not really re-inventing the wheel
02:17 PM fragalot: just reinventing the tyre :P
02:17 PM gloops: well, a bit more swatting for me or i wont be making any lions
02:20 PM MrHindsight: gloops: what's with all the 4-axis posts?
02:21 PM MrHindsight: gloops: gathering ideas?
02:21 PM gloops: sorry same one twice, thought some might find it interesting, the people on facebook like it
02:21 PM gloops: MrHindsight i will be making lions, this time next year
02:21 PM MrHindsight: comparing us to facebook people?!
02:22 PM gloops: for the wood people!
02:22 PM MrHindsight: never been so insulted in all my life! :)
02:23 PM fragalot: only gloops likes cutting dead things
02:23 PM fragalot: :3
02:23 PM gloops: i mean engineers are typically dour my nature, realistic worldly types
02:24 PM gloops: wood people on the other hand are more art orientated, imaginative, creative and so on
02:25 PM fragalot: certainly true for me.. square is nice. square is good.
02:25 PM fragalot: maybe a fillet on inside corners, or if you're going to walk into it
02:26 PM gloops: occassionally an engineer turns up...who dares to dream
02:26 PM MrHindsight: https://www.ted.com/talks/greg_gage_how_to_control_someone_else_s_arm_with_your_brain#t-203306 jump to ~2:00 minutes
02:27 PM MrHindsight: we should LCNC this
02:27 PM gloops: fragalot its only to be expected, engineers fight with hard reality on a day to day basis, their experiences teach them that reality is pretty inflexible
02:27 PM MrHindsight: G-code to control real human arms
02:27 PM gloops: good idea
02:27 PM gloops: can we keep the brains in glass jars marked 'normal' and 'abnormal'
02:28 PM MrHindsight: they stay alive when stored in blood filled meat sacks
02:28 PM gloops: brains?
02:31 PM gloops: i remember a TV series called 'cold lazarus' they got the dead bloke and wired him to a machine, so snippets of his memory could be viewed as video
02:31 PM fragalot: sounds like black mirror
02:32 PM MrHindsight: been a few books and films that are similar
02:32 PM gloops: when the started to piece the random fragments of memory together it turned out pretty sinister
02:32 PM MrHindsight: can you get someone to walk again that is brain dead?
02:33 PM gloops: yes
02:33 PM MrHindsight: there a fun project, life support with animated limb action
02:34 PM fragalot: no
02:34 PM fragalot: you can get the body to walk
02:34 PM fragalot: but the person is still dead
02:34 PM MrHindsight: just the brain
02:34 PM MrHindsight: people live all sorts of kick ass lives that way
02:36 PM MrHindsight: how to get attention on youtube
02:36 PM gloops: the brain is not dead, the neural and synaptic pathways may have decomposed but they can be reconstructed
02:36 PM MrHindsight: fun HS science fair project
02:36 PM MrHindsight: CNC control of peoples arms
02:37 PM gloops: we could bring about a state of existence beyond dead or alive
02:37 PM fragalot: MrHindsight: look at newer prosthetics
02:37 PM fragalot: similar concept, but the other wya 'round
02:38 PM MrHindsight: fragalot: sure, just considering ooohhh factor topics...
02:38 PM MrHindsight: without much merit
02:40 PM FinboySlick: MrHindsight: https://www.youtube.com/watch?v=sqwfDNzTYks <-- It reminded me of this.
02:40 PM FinboySlick: Cool band, btw. You can read the subtitles if you don't understand Swedish.
02:42 PM gloops: net home-z <= parport.0.pin-15-in
02:42 PM gloops: pin 15, input, joint 0 = home
02:42 PM gloops: a total novice can work out the hal file
02:45 PM gloops: net home-x => joint.*.home-sw-in <not sure what thats for though
02:45 PM fragalot: gloops: a child could work thato ut.
02:46 PM gloops: go on then
02:46 PM fragalot: I'm not a child.
02:46 PM gloops: i wasnt suggesting you were, what does it do?
02:47 PM gloops: this is picking up the button command to home x?
02:48 PM fragalot: gloops: net home-x signal goes to that joint
02:48 PM gloops: right
02:48 PM Wolf__: I found rtfm works wonders
02:48 PM gloops: is this python?
02:48 PM fragalot: doubt it
02:49 PM fragalot: gloops: fyi, the => just means the direction, for readability only as far as i know
02:49 PM MarcelineVQ: it's hal :>
02:50 PM gloops: im just trying to get a working grasp of these lines, i dont want to blindly depend on some ready made script
02:51 PM fragalot: all "net" does is map signals to pins and vice versa
02:52 PM gloops: or signals to joints
03:13 PM Tom_L: are jet products higher quality chinese crap or just crap?
03:15 PM Wolf__: use to be jet = Taiwan made crap
03:18 PM Wolf__: the 80’s jet mill I have seems quality
03:18 PM Wolf__: hand scraped ways
03:21 PM gregcnc: i exploded a Nikcole grooving tool yesterday. was parting small stock when boom and the entire insert was MIA. they work fine until you break a couple inserts, then the pocket is done.
03:22 PM gregcnc: I should have scrapped it a few inserts ago.
03:25 PM Tom_L: looking for vises
03:25 PM Tom_L: probably end up with a kurt or shars
03:26 PM Wolf__: like each end of the spectrum there lol
03:27 PM Tom_L: i thought shars was supposed to be a little better than some
03:30 PM MrHindsight is now known as CaptHindsight
03:31 PM Rab: I think Shars is the same basic china eBay stuff, but with some selectivity and QC. Maybe they work with manufacturers to maintain consistency. I've never gotten stuff from Shars that I thought was crap.
03:32 PM Tom_L: http://www.shars.com/products/toolholding-workholding/vise/4-440v-cnc-milling-machine-vise-0-0004-1
03:33 PM Tom_L: my bud offered to give me a 6" kurt but i'm not sure it'll fit on the table
03:33 PM Wolf__: turn it sideways
03:33 PM Rab: How big is your table?
03:34 PM Tom_L: 9 x 30ish
03:34 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Way_Cover.jpg
03:34 PM Tom_L: the height is the concern really
03:35 PM Tom_L: phipli, you find a board mfg?
03:36 PM phipli: ordered from seeed studio
03:36 PM Tom_L: mkay
03:36 PM phipli: £11.50 for 10 isn't too bad
03:36 PM Tom_L: not that thrilled about their quality but price is ok
03:36 PM phipli: interesting.
03:36 PM Tom_L: i used goldphoenix quite a bit
03:37 PM phipli: I saw a youtube video comparing the quality of a few manufacturers
03:37 PM phipli: but can't remember whos video it was
03:37 PM Tom_L: then mitch started selling them so i got a bunch from him
03:37 PM phipli: where are you, and they based?
03:37 PM Tom_L: i'm in US goldphoenix is in china
03:37 PM Tom_L: mitch is an aussie that peddles chinese boards
03:37 PM phipli: so similar delivery feasibility :)
03:38 PM phipli: I'm going to make electronic christmas cards this year
03:38 PM phipli: although I say that every year
03:38 PM phipli: if I can get them to make 4 in a single 100x100mm board I can get the boards for about 27p each...
03:38 PM phipli: then I just have to worry about the components
03:38 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/boards/USBTiny_Mkii/boards1.JPG
03:39 PM Tom_L: those were goldphoenix
03:39 PM phipli: how expensive were they if you don't mind my asking
03:39 PM Tom_L: i honestly don't remember now
03:39 PM Tom_L: that's been a few years back
03:39 PM Tom_L: and i don't order as much as i used to
03:40 PM Tom_L: join #hackvanna and ask mitch
03:40 PM Tom_L: he's the other one
03:40 PM Tom_L: -n?
03:40 PM Tom_L: yeah, #hackvana
03:41 PM Tom_L: the topic has links
03:42 PM phipli: :)
03:42 PM Tom_L: the quality of his is good
03:42 PM Tom_L: comparable to goldphoenix
03:42 PM Tom_L: or better
03:42 PM phipli: I rushed the traces on this one a bit
03:42 PM phipli: because I'm not pro I usually do a layout to work out how things clash
03:42 PM phipli: then move things and do it again using a marked up copy of the first one
03:43 PM phipli: but...
03:43 PM Tom_L: i'm no pro either
03:43 PM phipli: I got impatient
03:43 PM Tom_L: but i've done quite a few
03:43 PM Tom_L: some require gerber files others will just take your board file
03:43 PM phipli: like I mentioned, I was over the moon when I got my CNC and started cutting boards
03:43 PM Tom_L: with gerber there's about 6 or so files
03:43 PM phipli: although I've discovered that I can actually get surprisingly good component density on protoboard...
03:44 PM Tom_L: top & bottom copper, mask, silk, doc etc
03:44 PM phipli: I submitted gerber - 8 files total including the drill file
03:44 PM Tom_L: yeah i've got templates that generate them
03:44 PM Tom_L: for eagle
03:44 PM phipli: top + bottom of copper, silk screen, mask and one for milling
03:45 PM Tom_L: unless one is blank then i leave it out
03:45 PM phipli: what is the name of the package for a standard crystal osc?
03:45 PM phipli: HC18?
03:46 PM Tom_L: i use GC-preview on the gerbers
03:47 PM Tom_L: depends on the crystal
03:47 PM Tom_L: i've got some tiny smt ones
03:47 PM phipli: hum
03:47 PM Tom_L: what freq?
03:47 PM phipli: 12mhz - for the usb chip
03:47 PM phipli: I think I want a HC49
03:48 PM phipli: although I need to find some surface mount alternatives, because it is now one of the biggest components on my board
03:49 PM Tom_L: https://www.digikey.com/product-detail/en/murata-electronics-north-america/CSTCE16M0V53-R0/490-1198-2-ND/584406
03:49 PM Tom_L: see if that series has 12Mhz
03:49 PM Tom_L: i use those on my programmer
03:50 PM phipli: is that minimum order 3000?
03:50 PM Tom_L: it cuts the size down quite a bit
03:50 PM phipli: :)
03:50 PM Tom_L: they have singles, i just grabbed that link
03:50 PM phipli: excellent
03:50 PM phipli: thanks
03:50 PM Tom_L: https://www.digikey.com/product-detail/en/murata-electronics-north-america/CSTCE16M0V53-R0/490-1198-1-ND/584635
03:50 PM phipli: It is something I actually need to sort out
03:50 PM phipli: I actually skipped the AVR crystal just because it was so huge on the board!
03:51 PM Tom_L: i was using a crystal but switched to those
03:51 PM Tom_L: https://www.digikey.com/product-detail/en/abracon-llc/ABM8-16.000MHZ-B2-T/535-9134-1-ND/675651
03:52 PM Tom_L: that's the smallest crystal i could find
03:53 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/boards/USBTiny_Mkii/USBTiny_Mkii_index.php
03:53 PM Tom_L: you can see the resonator compared to the chip size there
03:53 PM phipli: http://elephantandchicken.co.uk/projects/NameTagATM8Render.png
03:53 PM phipli: difficult to hand solder?
03:54 PM phipli: do you use a heat gun for them?
03:54 PM Tom_L: no
03:54 PM Tom_L: i have a toaster oven but i hand soldered ~200 of those boards
03:54 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/boards/USBTiny_Mkii/USBTiny_Mkii.jpg
03:54 PM Tom_L: there's one using that crystal
03:55 PM Tom_L: quite a big bigger
03:55 PM Tom_L: i did make the pads under both a bit bigger
03:55 PM phipli: so the solder flows under
03:55 PM Tom_L: yeah
03:55 PM Tom_L: i use a flux pen
03:56 PM phipli: https://mikrokoszalin.pl/images/7122800.jpg
03:56 PM phipli: I have that
03:56 PM phipli: works /really/ well
03:56 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/boards/atmega32u4/atmega32u4_1.jpg
03:56 PM phipli: I also like that it is a thermo pasty
03:56 PM Tom_L: i hand soldered that just for the hellofit
03:57 PM phipli: home made arduino pro micro? :)
03:57 PM phipli: custom layout though...
03:57 PM Tom_L: probably before ardweenie was a thing
03:57 PM phipli: awesome
03:58 PM phipli: If all this works out I'm going to get some of my built in mcu relay board made up
03:59 PM Tom_L: what sort of relay board?
03:59 PM phipli: two relays to let you do a relay h-bridge for DC motors
03:59 PM Tom_L: oh
03:59 PM phipli: currently one down stairs has a atmega328 on it
03:59 PM phipli: and opto couplers etc
03:59 PM Tom_L: k
04:00 PM Tom_L: wondered if the relay was driven by the mega
04:00 PM Tom_L: HE101 will but they're not big enough for that
04:00 PM Tom_L: hamlin relay
04:01 PM phipli: the avr drives optos which drive transistors if I remember correctly
04:01 PM phipli: I only had 12v relays to hand at the time
04:01 PM phipli: and 5v optos :s
04:01 PM phipli: (input side)
04:02 PM phipli: can't remember the otherside of the optos, but it might have been the same
04:09 PM Phipliv: Heh. They just sent me a $10 voucher
04:09 PM Phipliv: Not bad for a $16 order
04:12 PM gloops: thats my kind of supplier
04:23 PM phipli: just soldered a SOT-23 mosfet to an adaptor board testing
04:23 PM phipli: that is one small mosfet
04:25 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/temp/tiny/tinyTPI1.jpg
04:25 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/temp/tiny/tinyboard1.jpg
04:25 PM Tom_L: yeah
04:25 PM Tom_L: sot23-6
04:26 PM Tom_L: tiny10
04:26 PM Tom_L: i don't do alot of that stuff anymore
04:27 PM phipli: hold your breath :)
04:28 PM phipli: I've gone 0805 for the passives
04:29 PM phipli: no real need to go smaller without reason I figure
04:29 PM Tom_L: 0603 is about right, 0402 is too small to be practical for hand soldering
04:30 PM phipli: I think I have some 0603 LEDs somewhere
04:30 PM phipli: but I've not used them
04:30 PM Tom_L: not any harder than 0804 but save a little more space
04:30 PM Tom_L: err 0805
04:31 PM Wolf__: worth its weight in fiberglass https://i.imgur.com/NmBhE34.jpg
04:32 PM Deejay: gn8
04:32 PM Tom_L: that looks like something ean would come up with
04:32 PM Wolf__: parts look too big in the cad stuff
04:36 PM JT-Shop: Tom_L: you getting this cold weather tonight? Our forcast keeps going down...
04:36 PM Tom_L: it's pretty chilly right now
04:36 PM phipli: excellent. the tiny mosfet works driving the LCD backlight
04:37 PM Tom_L: 37F
04:37 PM Tom_L: seems cooler but i've been cold all day
04:37 PM JT-Shop: we are 40°F and going to 17°F tonight
04:37 PM Tom_L: fun
04:38 PM Tom_L: weather guy predicts 19 for the low here
04:39 PM Tom_L: haha spirit got in trouble with OSHA
04:39 PM JT-Shop: phipli: Henry is still in the dog house
04:39 PM Tom_L: 200k for 6 violations
04:39 PM JT-Shop: spirit?
04:39 PM Tom_L: used to be Boeing
04:40 PM JT-Shop: ah
04:41 PM Tom_L: JT-Shop you have a 6" kurt vise?
04:41 PM phipli: is he still being cheeky?
04:41 PM phipli: or you just haven't forgiven him yet?
04:41 PM Tom_L: i need to figure out how tall they are to see if it would even fit under my Z column
04:42 PM Connor: Hmm.. I have a 2" face mill with 4 insets.. one of the screws for the inserts has broken off.. any idea on how to get it out?
04:42 PM Wolf__: kurt site has full measurements of their vises
04:42 PM JT-Shop: no, I have 3 paralec and 1 GMT standard type 6" vises
04:42 PM JT-Shop: yea he doesn't have his mind right yet
04:43 PM phipli: Connor : stud extractors?
04:43 PM Wolf__: Connor: left handed drill bit
04:43 PM phipli: Connor, random youtube video : https://www.youtube.com/watch?v=K34RS6M11uw
04:44 PM JT-Shop: I think all the standard 6" vises are the same dimensions 4 5/8" or so from the top of the jaw to the bottom
04:44 PM Tom_L: ok
04:45 PM Tom_L: i figured it was around the 4" plus area somewhere
04:46 PM Connor: Yea. I have some of those.. I hope it'll work.
04:47 PM Connor: It's a 2" ISCAR 4-insert face mill
04:48 PM phipli: drown it in WD40 first?
04:49 PM Wolf__: wd40 is worthless for that
04:49 PM Wolf__: kroil oil maybe
04:49 PM phipli: Connor, were you tightening or loosening it?
04:49 PM Rab: Connor, blind hole?
04:50 PM JT-Shop: water displacer 40 is not penetrating oil
04:50 PM phipli: it claims it is :)
04:50 PM Connor: I just picked it up from a guy.. Probably crashed it and knocked the insert off.
04:51 PM phipli: hopefully
04:51 PM phipli: lot more difficult if it broke because it was jammed when they were trying to take it out
04:52 PM JT-Shop: best I've found is PB Blaster it loosens your joints if you walk close to a can
04:52 PM JT-Shop: drill it from the back side maybe it will come out
04:56 PM Connor: I have access from back and front..
04:57 PM JT-Shop: the back is likely a better place to start a drill than the broken end
04:57 PM Connor: $150.00 for it and a slew of endmills and bunch of stubby drill bits.
04:57 PM Rab: Yeah, probably better luck from the back.
05:00 PM Connor: Taking pictures..
05:00 PM Connor: stand by
05:02 PM Connor: http://www.ivdc.com/cnc/IMG_3633.jpg http://www.ivdc.com/cnc/IMG_3634.jpg
05:05 PM enleth: Connor: do you have any ATF? also good as a penetrant
05:06 PM Connor: No.. I don't.. I'll have to go pick some up.
05:07 PM enleth: mix it 1:1 with acetone for better effect on oily stuff
05:07 PM Connor: How much is that cutter worth? 2" ISCAR
05:07 PM Wolf__: get a can of PB blaster
05:08 PM Connor: 45" 4 insert cutter
05:10 PM enleth: Connor: if you have a TIG and a very steady hand, you can also try welding something to the broken screw
05:10 PM Connor: yea. I'm not doing that..
05:10 PM enleth: anything as long as it's hardened
05:10 PM Tom_shop: ok, with the longest cutter i have i've got 4 3/4" to the table to the cutter
05:11 PM Tom_shop: but i generally use it for squaring block ends
05:12 PM Tom_shop: it's got a 1.75loc so fairly long for a tiny mill

05:32 PM Wolf__: sweet
05:33 PM roycroft: i just got some shielded cable in the mail
05:33 PM roycroft: it was sold as having a braided shield, which i can deal with easily
05:33 PM roycroft: it came with a foil shield
05:33 PM roycroft: i need to ground that at one end
05:33 PM roycroft: what do folks use to attach grounding lugs to a foil shield?
05:33 PM roycroft: with braided i would just soder it
05:34 PM roycroft: solder
05:34 PM roycroft: but i'm sure that's not going to happen with the foil
05:34 PM MarcelineVQ: doesn't foil still have a line running along it that you ground with?
05:34 PM roycroft: hmm, let me dig into it some more
05:35 PM roycroft: oh, yeah - when i cut it back farther there's a bare wire
05:35 PM roycroft: perfect
05:35 PM JT-Shop: yea usually foil has one ground next to the foil
05:35 PM CaptHindsight: inside view https://imagebin.ca/v/3qG2tpSzxO12
05:35 PM roycroft: the wire was shorter than the foil
05:35 PM roycroft: i did not see it until i cut the insulation back farther
06:27 PM Connor: I can't find this face mill.. it's a Iscar F45KT-D2.0-.750-R06
06:27 PM Connor: I see a 100mm version.. with more inserts.. but.. not this one..
06:27 PM Connor: guess it's discontinued..
06:35 PM CaptHindsight: https://i.imgur.com/EjYoQRt.png heh, taking that peacock story to the next level
06:39 PM CaptHindsight: Connor: ST version http://www.iscar.com/eCatalog/Family.aspx?fnum=2754&mapp=TG&app=0&GFSTYP=I
06:40 PM CaptHindsight: F45KT http://www.iscar.com/eCatalog/Item.aspx?cat=3101130&fnum=132&mapp=ML&GFSTYP=M&srch=1
06:41 PM Connor: yea, that's the one I kept finding.. 100mm
06:41 PM CaptHindsight: send them an email or call
06:42 PM Connor: Trying to figure out the condition of the inserts.. I found those..
06:42 PM Connor: Guess that's all i really care about.. and a replacement screw.
06:43 PM Connor: Uses octagon inserts..
06:44 PM Connor: I have a total of 12. I've not really used inserts before.. so I have not idea what they're suppose to look like or if they're any good.
06:56 PM Tom_L: https://www.youtube.com/watch?v=GtFTRyS__Yc&feature=youtu.be
06:56 PM Tom_L: good nuf
06:57 PM Connor: Tom_L: Tramming it in?
06:57 PM Connor: Shouldn't have been trammed from when you drilled the holes?
06:57 PM Tom_L: it's all good
06:58 PM Tom_L: square enough for holddown bolts
06:58 PM Tom_L: before i fine tuned it
06:59 PM Connor: https://www.ebay.com/itm/Iscar-2-034-Indexable-Milling-Cutter-Face-Mill-F45KT-D2-00-750-R06-4-Flute-/332506582047?nma=true&si=2d9qXcE6l9uWMYZ6VzwWH7OnpSU%253D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557
06:59 PM Connor: Wow.. that's the same as I have.. but man, that one is in bad shape..
07:00 PM Tom_L: you can get a new one for 3x that
07:00 PM Tom_L: well at least
07:00 PM Connor: $220.55
07:00 PM Connor: http://www.pitstool.com/pdf/l0378.pdf
08:15 PM Connor: Good grief. Replacement screw costs $1.80. I have to buy 5.. So, $9.00, + tax, $2.01 and.. the shipping.. $12.79 Total: $23.80 !!
08:23 PM Tom_L: get them somewhere else

09:15 PM Cromaglious_: need to register some more nicks...
09:15 PM Cromaglious_: My CNC Fusion kit cam in today. Recording video of putting it in
09:51 PM Connor: WooT!! I got the broken screw out of the face mill! No need to soak it in penetrating oil or anything... it was loose enough I worked it out with a pick and then got enough exposed I could grip it with pliers and back it out.
09:52 PM Tom_L: nice one
09:52 PM Connor: Now, I have to buy replacement screw...
09:53 PM Connor: Better find some other stuff to add to the order to make up for the shipping..
09:53 PM Tom_L: what size are they?
09:53 PM Tom_L: i bet you can find them somewhere
09:53 PM Connor: https://www.mscdirect.com/product/details/60848041
09:53 PM Connor: That's the screw.
09:54 PM Tom_L: M4 cap screw
09:55 PM Connor: What about the shoulder?
09:55 PM Connor: I'm sure that's to keep the insert perfectly centered..
09:55 PM Rab: Yeah, might be able to replace it with a flat head.
09:56 PM Rab: But considering the duty, it might be worth getting the OEM part.
09:57 PM Connor: $12.79 for UPS shipping..
09:57 PM Tom_L: ask em to put it in a shipper envelope
09:57 PM Tom_L: and send it USPS
09:58 PM Connor: You know what.. MSC has a local branch...
09:58 PM Tom_L: i'd all and ask for a person
09:58 PM Tom_L: call
09:58 PM Rab: Connor, you're getting a spare too?
09:59 PM Connor: 5 minimum quantity.. so yea..
09:59 PM Connor: Freaking H.. the branch is 10 minutes from my house.. I think I'll zip by them tomorrow and place a order locally.
10:00 PM Connor: I was trying to figure out why they were charging tax...

10:08 PM zeeshan: any of you guys in TN?
10:09 PM roycroft: https://www.ebay.com/itm/160772365717
10:09 PM roycroft: that's actually a better match
10:12 PM Connor: zeeshan: I am. :)
10:12 PM zeeshan: ill be in clarksville/nashville/cumberland city
10:12 PM zeeshan: mostly clarksville
10:12 PM zeeshan: any suggestions for food? :D
10:12 PM zeeshan: there for work :P
10:12 PM Connor: No Clue.. that's about 2 hrs to the west of me.
10:16 PM roycroft: those screws i linked to are in eastern pa, connor, so not terribly far from you
10:16 PM Connor: I'll check the local MSC branch and see what the deal is.
10:16 PM Connor: If they can't get them in.. then I'll order those.
10:17 PM roycroft: yeah, if you have a local msc outlet that would probably be the best bet
10:17 PM Connor: 5.6 miles from the house.
10:17 PM roycroft: knowing msc, if they don't have them at that branch they'll have to order from a warehouse and it will take a while and you will still pay shipping
10:18 PM roycroft: but certainly check with them first
10:18 PM Connor: You think they won't ship the to the branch at no-charge?
10:18 PM roycroft: i think there's a good chance that if they will it will have to be on a regular order and might take a long time
10:19 PM Connor: I'm not in a hurry.
10:19 PM roycroft: i don't have the greatest impression of msc, as might be obvious
10:20 PM roycroft: if you're spending $50k/year with them they're probably a good tooling supplier
10:22 PM Tom_L: zeeshan!
10:22 PM Tom_L: what's up?
