[03:14:44] <Deejay> hey there
[03:15:00] <Deejay> frag-a-lot
[03:15:34] -!- veek has quit [Quit: Leaving]
[03:16:09] -!- syyl has joined #linuxcnc
[03:17:16] <fragalot> syyl: I like your new spindle lock!
[03:17:26] <syyl> :)
[03:17:29] <syyl> thanks :D
[03:18:15] <fragalot> can you leave it in place, or do you need to take it off for normal milling?
[03:19:17] <syyl> definetly have to take it off
[03:19:25] <fragalot> shame
[03:19:35] <fragalot> still a lot easier than the nut to dial things in though I bet
[03:19:42] <syyl> ho yes
[03:19:44] <syyl> oh yes
[03:19:45] <syyl> :D
[03:19:45] <fragalot> :D
[03:20:03] <fragalot> on the schaublin I currently use the drawbar itself with a larger washer to lock it
[03:20:24] <fragalot> which is.. not ideal. :D
[03:20:32] <syyl> haha
[03:20:38] <syyl> just like the nut i was using before
[03:20:42] <syyl> "not ideal"
[03:21:25] <fragalot> are you using integers or floats on that arduino for the angle math?
[03:21:57] <syyl> double
[03:22:19] <fragalot> don't forget to add 0.5 steps to get rid of the rounding errors then
[03:22:25] <fragalot> when converting back to ints
[03:22:59] <syyl> hu?
[03:23:04] <syyl> (<- no programmer)
[03:23:17] <fragalot> say that it calculates you need 15.6 steps
[03:23:32] <fragalot> when you convert it back to ints to send it out to the drive, the default behavior is to truncate the 0.6
[03:23:44] <fragalot> if you add 0.5, it makes that 16.1 and truncates to 16
[03:23:49] <fragalot> which is less error
[03:23:54] <syyl> oh, right
[03:24:02] <renesis> real mfkrs fixed point
[03:24:07] * renesis shifts all the things
[03:24:13] <syyl> i think thats not much of an issue, as i am using 1/8 microstepping
[03:24:22] <syyl> i need a lot of steps for tiny movements ;)
[03:24:33] <syyl> (1800 per rev)
[03:24:34] <fragalot> renesis: used to do the same on the older CPU's. modern ones have dedicated FPU cores
[03:24:47] <fragalot> syyl: it's the principle of the matter! :D
[03:24:50] <syyl> (1800 on the motor that is)
[03:24:53] <syyl> yeah :D
[03:24:55] <syyl> i understand
[03:24:58] <renesis> still faster a lot of the time
[03:25:08] <syyl> will look into it - the code is not finished anyway
[03:25:15] <syyl> its still partialy broken
[03:25:17] <fragalot> renesis: very true. if needed I still use fix point for high speed stuff
[03:25:38] <fragalot> but rather than using it /EVERYWHERE/ I've started using floats where they make sense
[03:34:24] <miss0r2> mornin'
[03:35:22] <fragalot> morning
[03:36:04] * miss0r2 is trying to locate a new oil filter for the landrover :)
[03:36:13] <miss0r2> This morning it started bypassing :D
[03:36:42] <fragalot> ._.
[03:37:10] <fragalot> never realized that landy's needed an oilfilter
[03:37:29] <miss0r2> Hehe.
[03:37:30] <fragalot> I mean. do they even have a return circuit for the oil?
[03:37:46] <miss0r2> Funny man - I knew what you were getting at.
[03:37:48] <miss0r2> :D
[03:37:50] <fragalot> l:-)
[03:38:01] <syyl> are landrovers prone to loose oil?
[03:38:06] <fragalot> and parts
[03:38:10] * miss0r2 slaps syyl
[03:38:24] <miss0r2> Its a fine vehicle!
[03:38:25] <miss0r2> :D
[03:38:32] <fragalot> for sophisticated people :d
[03:38:43] <syyl> you know why the front wheel well of a landrover defender is flat?
[03:39:00] <syyl> to prevent the toolbox from falling off.
[03:39:24] <miss0r2> I mean; I did the first oil & filterchange on it for perhaps 20 years... Its only fair the filter has alot of grime to remove
[03:39:32] <syyl> (a friend of mine, who had a defender used to tell that joke)
[03:39:38] <miss0r2> syyl: 70% of landrovers sold are still on the road - the rest made it home
[03:39:45] <fragalot> xD
[03:39:45] <syyl> lol :D
[03:40:33] <miss0r2> also: When the land rover ingeneers designed the first landrover, they started with a clean shop floor, threw a bucket of oil on the floor and build their way up from there
[03:40:49] <syyl> haha
[03:40:50] <miss0r2> Yup - I've heard them all ;]
[03:40:57] <fragalot> have you?
[03:41:00] * fragalot starts googling
[03:41:01] <miss0r2> try me.
[03:41:12] * miss0r2 already did some extensive googling...
[03:41:24] <miss0r2> I find most of them hilarious
[03:41:24] <syyl> (to be onest, i would wouldnt mind a landrover)
[03:41:30] <fragalot> wow there's a lot of dross in these
[03:41:46] <miss0r2> syyl: I completely understand :)
[03:41:51] <fragalot> Why do Land Rovers have jerry cans and gas bottles fitted?
[03:42:02] <fragalot> so the driver can make tea while waiting for road assistance
[03:42:07] <miss0r2> lol
[03:42:13] <miss0r2> okay, I can't remember reading that one
[03:42:21] <fragalot> they also have the best fuel consumption of all 4x4's out there
[03:42:25] <fragalot> because they are usually the one being towed
[03:42:45] <miss0r2> yeah
[03:42:48] <fragalot> what do you call a landy with brakes?
[03:42:50] <fragalot> custom.
[03:43:08] <miss0r2> I've read it as: "Because their primary propulsion is a land cruiser"
[03:43:09] <fragalot> syyl: same, but not as my daily driver
[03:43:21] <syyl> haha
[03:43:32] <miss0r2> syyl: https://imgur.com
[03:43:44] <miss0r2> It looks tired on the outside, but underneath it is sparkling..
[03:43:45] <syyl> aww cool
[03:43:50] <miss0r2> Its like a sleeper - only slow all the time
[03:43:52] <fragalot> friend of mine has a satana anibal
[03:43:59] <fragalot> which is like a landy, but with more problems
[03:44:03] <syyl> looks like a group of green berets just jumped out of that one and went on mission
[03:44:10] <syyl> love the look of that car
[03:44:47] <fragalot> I love how none of the panels are in the same color :D
[03:45:05] <miss0r2> syyl: be carefull not to catch the 'english sickness"
[03:45:15] <syyl> mean: english car?
[03:45:33] <fragalot> miss0r2: did you fit that bracket yet?
[03:45:33] <miss0r2> mean: love for old english cars
[03:45:43] <syyl> oh
[03:45:45] <syyl> that wont happen
[03:45:54] <miss0r2> fragalot: yeah, it works a charm
[03:46:01] <miss0r2> no pictures of it though, installed that is
[03:46:08] <fragalot> did you wind up tapping the plate as-is then?
[03:46:17] <syyl> apart from the defender, i find most (all?) british cars...not very appealing :D
[03:46:20] <fragalot> or TEC7'd it on :D
[03:46:33] <miss0r2> fragalot: I ended up using those threaded rivets
[03:46:39] <fragalot> good. :-)
[03:47:33] <fragalot> I need to make me one of those no-spill oil pots >*>
[03:47:42] <fragalot> just knocked my little cup over twice
[03:50:14] -!- CaptHindsight has quit [Remote host closed the connection]
[03:51:01] <miss0r2> syyl: Defenders are the "new age" stuff
[03:51:08] <miss0r2> Coil springs'n such
[03:51:16] <syyl> fancy ;)
[03:51:34] <fragalot> friend of mine blew out the dampers on his
[03:51:42] <fragalot> and he hasn't fixed them yet... quite an interesting ride
[03:51:44] <miss0r2> syyl: Did you scroll down on the imgur link I posted? There you can see underneath
[03:51:47] <miss0r2> lol
[03:52:05] <syyl> hey
[03:52:19] <syyl> leaf springs :D
[03:52:43] <miss0r2> fragalot: I'm comming to think of that top gear episode: "Traditionally shock absorbers are attached at both ends, right?"
[03:52:58] <miss0r2> syyl: Proper uncomfortable ride :D
[03:53:02] <fragalot> when I first picked up my renault twingo, the springs were attached on both ends
[03:53:09] <fragalot> sadly they were no longer connected in the middle
[03:53:23] <miss0r2> haha
[03:53:33] <fragalot> good car, that
[03:53:42] <miss0r2> as designed, nontheless
[03:53:56] <fragalot> my sisters' got it now, and I think it's up to 340.000km now with a little dinky petrol engine
[03:54:37] <miss0r2> You gotta love that
[03:55:01] <miss0r2> My brother in law had a Toyota starlet. 1.6l petrol engine. He SOLD it when it hit 500.000
[03:55:01] <fragalot> yeah, it's due new springs again soon
[03:55:05] <fragalot> they only last 120k :P
[03:55:08] <syyl> there are a bunch of tiny cars that just dont want to die
[03:55:09] <miss0r2> hehe
[03:55:21] <syyl> with engines the size of a hamster
[03:55:39] <miss0r2> good for economy, bad for selfesteem :)
[03:55:54] <fragalot> the thing I liked most about that twingo was the windows
[03:55:58] <fragalot> they are HUGE
[03:56:09] <miss0r2> https://i.imgur.com
[03:56:22] <syyl> lol
[03:56:33] <syyl> if i have to fix my selfesteem with a car
[03:56:33] <fragalot> :D
[03:56:37] <syyl> somethings wrong ;)
[03:57:08] <miss0r2> That the downfall of the land rover - small windows.. AND I put a spare wheel on the bonnet... I wouldn't be able to see a small kid on a tricycle in front of me, within 30 meters :D
[03:57:34] <miss0r2> Land rover - A british tank with the strength of a car
[03:57:36] <fragalot> yea...
[03:58:52] <miss0r2> fragalot & syyl: Consider you both invited to come help paint the land rover this summer ;)
[03:58:57] <miss0r2> I'll make a nice BBQ'n such
[03:59:02] <syyl> well
[03:59:05] <syyl> i am a terrible painter
[03:59:18] <miss0r2> This is a land rover, not the 16th chapel
[03:59:21] <syyl> :D
[03:59:24] <fragalot> I'd be delighted to help eat the bbq
[03:59:28] <miss0r2> also - you and me both
[03:59:30] <syyl> so spitfire green it is?
[03:59:42] <syyl> (another top gear reference)
[03:59:48] <miss0r2> olive green (brother in law works for the army - he can "source" free paint)
[04:00:01] <fragalot> still think it's a shame that top gear ended the way it did
[04:00:09] <syyl> everyone in the military can source paint, it seems
[04:00:10] <syyl> haha
[04:00:13] <fragalot> and their new show is only on amazon which sucks
[04:00:26] <fragalot> i'm not signing up to every single video service on earth just because "they have that one show"
[04:00:28] <miss0r2> fragalot: Meh.. theres plenty of places to watch it online
[04:00:28] <syyl> let me rephrase that
[04:00:37] <miss0r2> syyl: Waiting in excitement :P
[04:00:38] <syyl> [10:00:13] <fragalot> and their new show (is only on amazon which) sucks
[04:00:45] <miss0r2> lol
[04:00:54] <miss0r2> Some of their new stuff is still rather funny I think
[04:00:58] <fragalot> syyl: I heard "it gets better" -- but haven't watched any myself
[04:01:08] <miss0r2> But then again, I've only ever liked their special episodes
[04:01:14] <syyl> top gear always felt a bit shitty
[04:01:18] <fragalot> of course
[04:01:21] <miss0r2> if you stop thinking about how staged it all is, you can have fun watching it
[04:01:24] <fragalot> but it was a special kind of shitty
[04:01:27] <syyl> yes
[04:01:31] <syyl> absolutely
[04:01:35] <syyl> loved it
[04:01:38] <fragalot> :D
[04:01:41] <syyl> the amazon series feels wrong
[04:01:59] <fragalot> probably still trying to find their place, with a new budet
[04:02:01] <fragalot> budget
[04:02:02] <syyl> feels made for american audience
[04:02:06] <miss0r2> three old gents bickering? I don't care where they broadcast that
[04:02:07] <fragalot> because it is
[04:02:50] <miss0r2> fragalot: Seriously though, start planning a trip with the misses to denmark this summer ;)
[04:03:02] <syyl> and james may has a myford lathe
[04:03:04] <fragalot> I'll need to check with the misses
[04:03:08] <syyl> (!)
[04:03:10] <fragalot> I know we already have something planned in the UK
[04:03:13] <fragalot> but I forgot when
[04:03:14] <syyl> (of course he has)
[04:03:22] <fragalot> syyl: I kinda like may
[04:03:30] <miss0r2> fragalot: You can bring me cheap parts then ;)
[04:03:37] <fragalot> always a shame that his TV characters' thing is that he's held back & ignored
[04:04:15] <miss0r2> bah... Have you ever realy watched his shows? He likes to come off as a real handyman sorta type. but alot of the stuff he does is down right stupid
[04:04:20] <fragalot> has anyone seen the ballad of buster scruggs yet?
[04:04:37] <fragalot> i've only ever watched like 2
[04:04:53] <fragalot> one where he made a toy train go around the UK, and one where he built a lego house
[04:05:27] <miss0r2> as much as I enjoy being part of a three gent bickering squad - I need to prepare for newyears eve (With a 10 day old baby on my arm). I will have to leave you to it. See you around
[04:05:37] <fragalot> same, but without the baby
[04:05:41] <miss0r2> :]
[04:05:43] <fragalot> happy new year! :-)
[04:05:47] <miss0r2> you too. Vya
[04:05:49] <syyl> https://twitter.com
[04:06:28] <fragalot> love how that went political within the first few comments
[04:07:02] <syyl> dont read comments :D

[06:25:09] -!- candyonetoo has joined #linuxcnc
[06:29:15] <fragalot> syyl: I think i've decided to make my own ELS.. all I really want is an infinite leadscrew ratio, and I feel the rocketronics ELS is a bit too 'complex' for that.
[06:29:24] <fragalot> syyl: but before I re-invent the wheel: do you know of any others?
[06:30:35] -!- njh has joined #linuxcnc
[06:30:41] <syyl> nope, thats the only one i know off
[06:30:46] <syyl> and yes, that would be all i need too :D
[06:30:59] <fragalot> right. :-)
[06:31:17] <fragalot> I'll see if i have a spare nucleo board lying around
[06:31:27] <fragalot> I know that hardware is much more capable than an arduino for high resolution stuff
[06:33:20] <Wolf__> hey jthornton, I need some mesa hardware advice, I seem to have forgotten all the research I had put in before lol what would you suggest for a ethernet plasma table build running step/dir (stepper or maybe clearpath later on)
[06:49:43] <The_Ball> Hi guys, is it possible to access machine coordinates G53 in gcode? I can't find #5XXX variables for them
[06:50:27] <jthornton> lots of choices lol 7i92 + 7i76 or 7i78, 7i76e, 7i96
[06:55:11] <Wolf__> I’m leaning towards the 7i76e unless there is a compelling reason to go with the 7i92+7i78, tho I’m trying to keep this build somewhat simple lol
[06:57:05] <jthornton> it just depends on you I/O needs and axis count if a 7i76e or 7i96 would fit the bill
[06:59:32] <jthornton> I don't see absolute coordinates in any of the variables, what are you trying to do?
[07:00:43] <Wolf__> just a simple gantry build, dual Y axis motors, X and Z for THC
[07:02:42] <Wolf__> oops, its was the 7i96 I was looking at
[07:03:41] -!- phipli has joined #linuxcnc
[07:11:56] -!- oscarslovo has joined #linuxcnc
[07:15:03] <The_Ball> jthornton, I've got a toolsetter on the table, so I want to access the machine coordinates to calculate probe moves in what ever coordinate system the machine is in. So you can't probe in G53 so I need to know how far to probe in whatever coordinate system is currently selected
[07:15:18] <The_Ball> I could be approaching this in the wrong way of course :)
[07:16:48] <Wolf__> hmm, I think my build is simple enough that even the 7i96 seems like overkill lol
[07:17:50] <jthornton> The_Ball: can't you just do a G53 move to some position then you know the location your at?
[07:23:10] -!- JesusAlos has quit [Quit: JesusAlos]
[07:24:31] <The_Ball> jthornton, I do that yes, but if I then do a probe towards Z0 that will be in the current coordinate system, so the probe could go upwards or stop downwards mid air
[07:25:22] <The_Ball> I was thinking of grabbing the G53 to current coordinate system offset and using that for the probe move, but seems overly complex for something simple
[07:25:45] <gregcnc> That seems to be common method.
[07:25:53] <jthornton> why not change coordinate system?
[07:26:36] <The_Ball> jthornton, sure, next issue, I don't know what coordinate systems are used for what
[07:28:27] <The_Ball> My mill goes up to Z450, so I guess I could do something like G53 Z450, then G38.2 Z[#5422 - 450]
[08:06:26] <The_Ball> I think this should work https://pastebin.com

[10:46:43] <fragalot> I wonder if you could persuade a ballscrew nut to spin freely in place, and then grab on to it to make the axis move
[10:46:52] <veek> durn that hit the line as i exited :p

[10:47:00] <jthornton> is it 2019 somewhere now?
[10:47:04] <fragalot> yes
[10:47:16] <fragalot> forgot where but it was in the news earlier today because there's nothing else to report on
[10:47:21] <gloops> veek must be on the Aus side
[10:47:28] <pcw_home> Sidney
[10:47:30] <gloops> down under
[10:47:35] <jthornton> ah
[10:48:06] <gloops> fragalot not possible
[10:48:17] <fragalot> gloops: why not?
[10:48:29] <gloops> balls would fall out
[10:48:36] <fragalot> you understood me wrong
[10:48:40] <fragalot> the nut remains standard
[10:48:53] <fragalot> but you don't stop it spinning in place
[10:49:02] <fragalot> ergo, it's not moving anywhere
[10:49:19] <fragalot> then you engage a clamping system onto it to stop it spinning, at which point the carriage gets pulled along
[10:49:21] <gloops> assuming you are driving the screw - a clutch on the screw drive mechanism might work
[10:49:28] <fragalot> exactly
[10:49:43] <gloops> but then, why would you need that if you have step/angle control
[10:50:05] <fragalot> less backlash when reversing
[10:50:15] <fragalot> it was just a thought - don't really have a practical application in mind
[10:50:55] <gloops> just overshoot every pass - no backlash
[10:51:30] <gloops> or no..cut from one side only
[10:51:43] <fragalot> that's the standard way of working, yes

[11:09:23] <gloops> jesseg like a skytracker?
[11:10:16] <jesseg> not sure what skytracker is but yeah a 2 axis motorized equatorial telescope mount for finding and tracking sidereal
[11:12:07] <gloops> yes i image so, if you get the maths right
[11:13:25] <gloops> ive seen photos taken with manual trackers that are pretty good - like turn by hand every so many seconds
[11:14:15] <jesseg> yeah
[11:14:56] <jesseg> but for any level of magnification you really need a constant motion for sidereal..
[11:15:29] <fragalot> jesseg: you could use it for a pentax K-1
[11:15:30] <jesseg> I mean you can see the moon moving dozens of pixels a second with even a modest zoom camera (not even a telescope)
[11:15:52] <fragalot> that one (ab)uses the in-body stabilisation feature to do static star-tracking based on pixel brightness
[11:16:00] <jesseg> I don't have a pentax K-1 :P
[11:16:16] <fragalot> maybe you should.
[11:16:17] <fragalot> :D
[11:16:31] <jesseg> I have some canon dslr rebel t2i or some nonsense
[11:17:00] <jesseg> and I haven't $1500 to throw around :P
[11:17:09] <fragalot> it's more if you include the lenses :D
[11:17:22] <gloops> it is easily achievable with stepper motors with 1.8 degree step and microstepping
[11:18:09] <jesseg> does look like a real nice camera though
[11:18:24] <jesseg> but anyway I'm stuck with what I got at the moment and it's fine to play with :P
[11:18:43] <gloops> any full frame dslr will get you the milky way with a run of the mill lens
[11:19:23] <jesseg> gloops, gear train slop is a real pain though.. which is why I'm thinking direct drive 6" harmonic drive
[11:20:01] <gloops> not important if you are stacking images
[11:21:08] <jesseg> lol sure it's important if gear slop allows your whole telescope to shift enough that your target object isn't even in view anymore :D
[11:21:44] <fragalot> gloops: I would love to see you try to get that shot where I live
[11:21:55] <fragalot> the camera doesn't matter, all you get is orange anyway :P
[11:22:04] <gloops> i mean you dont want to be taking ultra long exposures of the stars, too much noise
[11:22:55] <jesseg> and besides I also want to do visual observations and nice steady solid tracking would be real nice :P
[11:23:13] <fragalot> jesseg: some form of gearing would be required to have it move smoothly and reliably
[11:23:26] <fragalot> microstepping is fun and all, but it doesn't really improve your resolution reliably
[11:23:57] <gloops> what im saying is, the stacking software will align the images by points of reference, not the outer frame, doesnt matter if the view moves slightly between shots
[11:24:27] <jesseg> gloops, so help me understand where you're coming from on the noise issue if you might be so kind... An exposure 100x longer has 100x changes of more noise. But if you stack 100 pictures you get 100x the noise they each had... that may not be the exact math but stacking adds some noise too, doesn't it? Ultimately it's a question of SNR?
[11:24:46] <fragalot> jesseg: yes and no
[11:24:53] <fragalot> stacking can have the effect of cancelling out the noise
[11:25:15] <jesseg> fragalot, yeah that's why I'm thinking large format harmonic drives -- like those used in industrial robotic arm joints.
[11:25:49] <fragalot> overkill, no? :-)
[11:26:22] <jesseg> fragalot, I can see stacking canceling out hot pixels. I'm still trying to get my mind wrapped around the noise issue because there's always a signal to noise ratio and noise adds too, although may be at a lesser rate than signal
[11:26:29] <gloops> you want to talk to ozzzy, not sure if hes on ##photography or ##photogeeks on freenode, he is on #photography on undernet
[11:26:55] <gloops> hes got a webpage with his astro stuff, some noce work
[11:27:01] <jesseg> Overkill? Depends on how heavy telescope is, how much the wind is blowing, who's leaning on it while looking through the eyepiece, and how solid I want it
[11:27:16] <fragalot> jesseg: good point. carry on.
[11:27:39] <fragalot> but noise can often be filtered out if you have enough separate shots
[11:27:46] <fragalot> after all it's all an averaging game
[11:28:02] <fragalot> and if all you're interested in is stars, there are cheaty ways of accomplishing this
[11:28:14] <fragalot> I'm no expert but a colleague of mine at work won't shut up about it :D
[11:28:21] <jesseg> yes but shooting with a low ISO averages out truly random noise too
[11:29:03] <jesseg> and in fact shooting at minimum ISO is basically a more pure form of continuously stacking pictures :P (regarding random noise. Not so for hot pixels.)
[11:29:06] <gloops> ozzzy - try joining #photography youll be redirected to photogeeks, hes on there
[11:29:39] <jesseg> cool, thanks
[11:29:40] -!- ferdna has quit [Quit: Leaving]
[11:29:41] <fragalot> jesseg: not to mention that on some camera's there is no practical benefit to high ISO vs using the exposure slider in post
[11:30:39] <jesseg> fragalot, yeah if you're shooting raw certainly true. The only thing high ISO really does for you is bring some dark scenes to the point where jpeg compression doesn't throw everything away :P
[11:30:54] <fragalot> if you're using jpeg you've already lost :D
[11:37:27] <gloops> if you just want to watch through a telescope tracking isnt so vital

[18:24:43] <Rab> Looks like it's only 2 flutes.
[18:24:47] <gloops> maybe yeah, does look very fragile though
[18:24:50] <XXCoder> oh new bad obession video!
[18:25:05] <XXCoder> Rab: looked like 4 but if its 2 its fine, just too slow
[18:25:22] <XXCoder> gloops: I used 1/16 which is much smaller lol
[18:25:35] <XXCoder> far faster rpm and movement
[18:26:37] <XXCoder> happy new year btw
[18:26:44] <gloops> looked at some 30 degree, 20 and 10 v cutters i bet the tips are quick to snap off those too
[18:26:50] <Rab> Yeah, spindle max is 5140 RPM.
[18:26:57] <gloops> yes happy new year to all
[18:27:34] <XXCoder> wood you need pretty high rpm to keep chips from overloading and killing tool
[18:27:54] <Rab> Should be at least 4x that, probably.
[18:27:55] <gloops> 1mm = 3/64s
[18:28:00] <XXCoder> even at that rpm you still need faster movements
[18:28:22] <gloops> ive got some 2 mm theyre fine - i bought a bee vector, some very fine detail to pick out
[18:29:14] <gloops> it does seem to clog up or something before the tool snaps in the vid - like it stopped cutting
[18:29:19] <XXCoder> if you just dig in and make groove, you need air blow
[18:29:46] <gloops> https://www.amazon.co.uk
[18:30:10] <XXCoder> i have a set, still waiting for m,achine lol
[18:30:26] <gloops> 10 degree..thats very fine
[18:30:41] <Rab> I can't find a runout spec for the Tormach spindle, but that's prob not appropriate for carbide that small either.
[18:32:08] <XXCoder> lol my chineseium spindle has worse runout
[18:33:28] <gloops> i bet those 10 degree v bits make good edge finders actually
[18:34:00] <XXCoder> approx ones maybe
[18:34:23] <XXCoder> can do severial ways, like use endmill move it in and move shim till shim cant move
[18:34:28] <gloops> oh yeah, only for decorative woodwork
[18:34:35] <XXCoder> then edge is shim + rad of tool out
[18:35:00] <XXCoder> it can be accurate if you plan to make part completely inside stock anyway
[18:35:04] <XXCoder> just not very repeatable
[18:35:12] <XXCoder> since that side will be gone
[18:35:19] <Rab> I can't recommend cheap china conical cutters of any angle, at least for PCBs...tried them against real LPKF tooling and the difference was like night and day. The chinesium left terrible burrs and was just a mess.
[18:35:53] -!- CubicleNate has quit [Ping timeout: 245 seconds]
[18:36:12] <gloops> ive not tried any of those type of cutters yet, the chinese spiral cutters are ok for wood
[18:36:15] <Rab> The LPKF cutters even performed better in plastic.
[18:36:35] <XXCoder> heh tried nylon, its a nightmare
[18:36:47] <XXCoder> no wonder work we use so much coolant on it
[18:38:43] <renesis> did not read scroll...
[18:38:48] <renesis> someone needs pcb cutters?
[18:39:20] <gloops> no, was just looking at small fine tipped cutters for wood
[18:39:39] <renesis> oh
[18:39:44] <renesis> https://www.2linc.com
[18:40:30] <renesis> hard to get finer than that without being crazy fragile
[18:40:45] <gloops> i bought the pattern for this, gonna cut it with router https://www.fionakingdon.com
[18:41:05] <renesis> https://www.2linc.com
[18:41:15] <renesis> these worked really well for pcb, no idea about wood
[18:41:42] <renesis> do you want to go that deep?
[18:41:46] <gloops> should be ok, its only just touching it really
[18:42:11] <gloops> no you cant mill the fine cuts out on that - just v carve the top
[18:42:50] <Tom_L> if you went to the trouble to make inserts for it you could
[18:42:54] <gloops> round the honeycomb and wings etc - no problem with 2 mm bit at that depth
[18:43:08] <renesis> yeah conicals will work great for the fine parts, then you can do larger areas with 1/32 or 1/16 or something
[18:43:34] <gloops> wheres shes done the hair detail with scroll saw blade - router wont do that i dont think, or agonisingly slow
[18:44:01] <gloops> Tom_L not sure what you mean
[18:44:13] <renesis> crazy machinist talk
[18:44:47] <renesis> she hand cut that?
[18:44:54] <Tom_L> essentially you would be making 2 but make the first one the cutout part
[18:45:08] <renesis> i would have guessed water jet
[18:45:14] <Tom_L> you would have to spread it out some for the cutter
[18:45:19] <gloops> renesis yes - scroll saw
[18:45:28] <renesis> thats crazy
[18:46:08] <gloops> still not picturing that Tom_L lol
[18:46:44] <Tom_L> it wouldn't be practical but it would probably work
[18:46:52] <gloops> renesis when you see someone whos good with scroll saw - thats not a big thing to do really, they are really quick
