[00:02:53] <Contract_Pilot> Ahhh
[00:03:38] <JT-Shop> do you have a parallel port?
[00:03:40] <gregncnc> three months, uh oh i'm only 3 weeks in on an order I might end up with Pico
[00:05:24] <gregncnc> those of you doing rigid tapping how much encoder resolution do you have? Is anyone doing it without tension compression tap holders?

[00:06:30] <zeeshan|2> did you get it to work jt? :-)
[00:06:31] <JT-Shop> everyone is doing it without springy things
[00:06:37] <zeeshan|2> damn wifey yelling for dinner
[00:06:40] <zeeshan|2> =/
[00:06:54] <JT-Shop> no, errors lol
[00:07:03] <zeeshan|2> haha
[00:07:12] <Tom_itx> JT-Shop, when's your probe gonna arrive?
[00:07:42] <JT-Shop> dunno
[00:07:49] <Tom_itx> gregncnc yeah i'm even doing rigid tapping on a measly sherline
[00:08:41] <Tom_itx> i've got a 500 cpr encoder on the spindle
[00:08:56] <JT-Shop> gregncnc: can't recall but I may have a 1000 line encoder on the BP and not sure about the CHNC
[00:09:01] <Tom_itx> you could probably get by with less
[00:11:23] <JT-Shop> the forum seems to be much more active since the upgrade...
[00:11:48] <Tom_itx> wonder why
[00:12:10] <JT-Shop> dunno
[00:12:56] <Tom_itx> did you get your store fixed?
[00:12:58] <gregncnc> I'm thinking about doing gear tooth quadrature on my lathe, this would be low maybe 240CPR
[00:13:20] <JT-Shop> should work fine
[00:13:39] <zeeshan|2> tom whats the biggest tap you ran on the sherline
[00:13:41] <gregncnc> 24USD for 3 hall sensors vs 130 for a US digital encoder
[00:13:56] <Tom_itx> zeeshan|2, not very big.. the spindle is a tiny motor
[00:13:59] * JT-Shop listens to a little Steely Dan before retiring to the couch
[00:14:18] <JT-Shop> automationdirect.com
[00:14:19] <zeeshan|2> if you can tap a 10-24
[00:14:24] <zeeshan|2> youre already way ahead a tormach! :D
[00:14:34] <Tom_itx> i think that's what i did in the demo video
[00:15:10] <JT-Shop> zeeshan|2: features won't run on 10.04
[00:15:18] <zeeshan|2> why??
[00:15:19] <Tom_itx> https://www.youtube.com/watch?v=g99lUtjLfMU&feature=youtu.be
[00:15:21] <zeeshan|2> gives yuou errors?
[00:15:24] <Tom_itx> zeeshan|2 ^^
[00:15:26] <JT-Shop> python 2.7
[00:15:46] <Tom_itx> i don't think it would work without PID
[00:15:51] <zeeshan|2> nice tom
[00:15:55] <JT-Shop> I get other errors, I just read on the forum about 10.04
[00:16:08] <zeeshan|2> JT-Shop: if you run setup
[00:16:13] <zeeshan|2> you gotta change the path from 2.7
[00:16:14] <zeeshan|2> to 2.6

[00:20:48] <zeeshan|2> wow that baby indexs fast
[00:21:10] <JT-Shop> crashes fast too
[00:21:14] <zeeshan|2> lol
[00:21:32] <zeeshan|2> 5c collet doesnt look happy
[00:21:38] <zeeshan|2> some sharpnelk came :)
[00:21:40] <JT-Shop> 16c
[00:21:44] <zeeshan|2> oh
[00:22:00] <zeeshan|2> did it stop completely crashing
[00:22:04] <zeeshan|2> cause it ferrored?
[00:22:14] <JT-Shop> yea following error killed it
[00:22:22] <zeeshan|2> nice
[00:22:23] <zeeshan|2> love that.
[00:23:13] <JT-Shop> you watch the last one?
[00:23:38] <zeeshan|2> JT-Shop: you got a cool accent :)
[00:23:43] <JT-Shop> lol
[00:23:45] <zeeshan|2> very cow boyish
[00:23:56] <Tom_itx> the first one looked like you got hung up in the lathe :D
[00:24:18] <JT-Shop> freaked me out when it crashed
[00:24:19] <zeeshan|2> steepness is hard to judge in pov
[00:24:26] <JT-Shop> yea
[00:24:33] <JT-Shop> it's steep
[00:24:52] <Tom_itx> ahh i had the volume down... didn't notice the crash
[00:24:59] <zeeshan|2> do you guys have blackbears thee
[00:25:12] <zeeshan|2> im curious what that sharpnel was :)
[00:25:16] <zeeshan|2> was it the tool tip or the collet
[00:25:31] <JT-Shop> yea, I saw one the other day chewing on a deer
[00:25:38] <zeeshan|2> nice :P
[00:26:39] <JT-Shop> time to strap on the feed bag
[00:26:48] <JT-Shop> say goodnight Gracie

[01:40:32] <zeeshan|2> got linuxcnc-features working!!!!!!!!1
[01:40:38] <zeeshan|2> it was a config error in the .ini
[01:40:50] <zeeshan|2> it is still not embedded
[01:40:56] <zeeshan|2> but at least the standalone is outtputing code to axis :)
[01:41:07] <Tom_itx> nice
[01:41:14] <Tom_itx> document it
[01:41:22] <zeeshan|2> 3 clicks to do a rectangular bolt pattern
[01:41:23] <zeeshan|2> haha
[01:41:25] <zeeshan|2> im loving this
[01:41:46] <Tom_itx> will it run on 10.04?
[01:41:58] <Tom_itx> i may try it standalone if it does
[01:42:36] <zeeshan|2> yes it will
[01:42:43] <zeeshan|2> but youre gonna have to change a couple things for it to install right
[01:42:49] <zeeshan|2> its not a lot of work
[01:42:52] <Tom_itx> document it!!!
[01:42:52] <zeeshan|2> once you figure out the steps
[01:42:59] <zeeshan|2> no!
[01:43:01] <zeeshan|2> install it now!
[01:43:03] <zeeshan|2> and see if it works
[01:43:07] <Tom_itx> i can't right now
[01:43:11] <zeeshan|2> tommo
[01:43:24] <zeeshan|2> basically you download as instructed on the github
[01:43:41] -!- rigid has quit [Max SendQ exceeded]
[01:43:42] <Tom_itx> working on a catia part atm
[01:43:43] <zeeshan|2> then edit the setup file inthe linuxcnc-features folder and change the 2.7 to 2.6 for python
[01:43:48] <zeeshan|2> and then add the lines :
[01:44:04] <zeeshan|2> program_prefix = path/to/linuxcnc-features/scripts
[01:44:30] <Tom_itx> does it run from axis then?
[01:44:39] <zeeshan|2> uinder rs274, subroutine_path = path/to/linuxcnc-features/lib
[01:44:44] <zeeshan|2> now you can run the standalone and it works
[01:44:52] <zeeshan|2> im still trying to get the embedded version to work
[01:45:05] <zeeshan|2> it loads up the linuxcnc-features program
[01:45:08] <zeeshan|2> but not the actual program
[01:45:12] <zeeshan|2> so reading a bit more
[01:45:49] <Contract_Pilot> Also need some 2.75" X 6" X 6" plate

[01:50:26] <zeeshan|2> yes
[01:50:28] <zeeshan|2> 100%
[01:50:41] <zeeshan|2> theres a lot of times im just circle milling like 4 holes in a plate
[01:50:43] <zeeshan|2> and doing some bolts
[01:50:48] <zeeshan|2> i can do it on the machine now
[01:50:53] <zeeshan|2> also slots
[01:51:03] <zeeshan|2> going to be super useful
[01:51:25] <zeeshan|2> its basically conversational
[01:58:09] <zeeshan|2> i just learned
[01:58:13] <zeeshan|2> 'bobo' stands for "fool"
[01:58:16] <zeeshan|2> in spanish
[01:58:20] <zeeshan|2> i think bobo has been trolling us :)
[02:00:14] <toastyde1th> i wonder how fast i can drill four holes on a plate freehand
[02:00:21] <toastyde1th> I've never timed myself cnc vs totally manual

[02:09:29] <zeeshan|2> finally i got it working
[02:09:38] <zeeshan|2> toastyde1th: a cnc will beat you every time :)
[02:09:44] <zeeshan|2> at least it beats me every time
[02:10:17] <zeeshan|2> Tom_itx: got the embedded tab working
[02:11:03] Protractinium is now known as Praesmeodymium
[02:11:50] <toastyde1th> ?
[02:11:54] <toastyde1th> I beat cnc all the time
[02:12:11] <toastyde1th> i just don't know if i can beat something like a bolt hole pattern
[02:13:05] <toastyde1th> I would cut short-run parts (1-5 or 1-10, based on complexity) on manual machines frequently because the total time was shorter up to a point
[02:13:16] <MrSunshine> https://www.youtube.com/watch?v=OpXTIskm-yY
[02:13:21] <MrSunshine> now thats ... what i call porn
[02:13:38] <zeeshan|2> how do you beat it for even a single hole?
[02:13:42] <zeeshan|2> you feed inconsistently
[02:13:46] <zeeshan|2> where it consistently feeds
[02:13:48] <toastyde1th> ?
[02:13:55] <toastyde1th> okay, so two machinists are handed a drawing
[02:14:00] <toastyde1th> and you say "go"
[02:14:11] <toastyde1th> the CNC is much faster in the cut, no question
[02:14:17] <zeeshan|2> if its just one hole
[02:14:25] <zeeshan|2> i have a center drill tool setup always
[02:14:34] <zeeshan|2> the only thing i'd hjave to do is load up a tool
[02:14:47] <zeeshan|2> and g83 it up
[02:15:00] <toastyde1th> this is why I'm curious if I would beat a cnc for a bolt pattern
[02:15:45] <toastyde1th> for very simple stuff like that where the machine is already half set, it can work in the machine's favor
[02:16:26] <XXCoder> heys
[02:16:52] <MrSunshine> in the wood working shop my cnc beats my hand skills hands on :P
[02:17:02] <toastyde1th> because I would probably do it on a drill press rather than a mill, because I can scribe a circle and mark it pretty quickly
[02:17:23] <MrSunshine> on flat goods :P
[02:17:29] <toastyde1th> on round goods too
[02:17:42] <toastyde1th> it's not like I never have to cut things that are round
[02:17:47] <XXCoder> I guess if theres unusual bolt hole pattern cnc is faster + more accurate
[02:17:57] <toastyde1th> round goods are often easier to do than square ones because of the radial symmetry
[02:19:33] <toastyde1th> threads are another good example where the cnc almost always wins
[02:19:34] <zeeshan|2> i had to think about it
[02:19:42] <MrSunshine> but yeah, some stuff its alot faster just to go to the manual tools . specialy on small series =)
[02:20:03] <toastyde1th> even doing stuff like bolt holes, you have to set work height and x/y
[02:20:09] <toastyde1th> even with a ready drill
[02:20:14] <zeeshan|2> if youre doing one hole, and youre doing a stadnard center drill and drill
[02:20:17] <toastyde1th> if you're lucky there's a useful stop
[02:20:21] <toastyde1th> and you already know
[02:20:24] <zeeshan|2> manual guy would win (and thats why i have a drill press) :P
[02:20:32] <zeeshan|2> but i think at 3 holes, a cnc mill would win
[02:20:34] <toastyde1th> even for several holes, it's very easy to change tools
[02:20:41] <zeeshan|2> cause you'd need to probe the drill tool
[02:20:46] <zeeshan|2> and type in the g83 code
[02:20:47] <XXCoder> zeeshan|2: not if dead simple, like in row
[02:20:57] <zeeshan|2> XXCoder: doesnt matter
[02:21:01] <zeeshan|2> you still gotta read a dro
[02:21:02] <zeeshan|2> it takes time.
[02:21:08] <zeeshan|2> while the cnc is rapiding between the 3 holes
[02:21:27] <toastyde1th> you are oversimplifying the process to program a cnc for a real part
[02:21:28] <zeeshan|2> and changing the tool by itself between the center drilling and drilling
[02:21:37] <zeeshan|2> am i?
[02:21:44] <zeeshan|2> it is really simple to program a drill pattern
[02:21:49] <zeeshan|2> and even simpler now with linuxcnc-features
[02:21:51] <toastyde1th> generally I do not want scrap, and typos are too common
[02:21:52] <zeeshan|2> its 3 clkicks
[02:22:26] <toastyde1th> it is also really easy to overlook work offset issues that you do not catch without a proof run
[02:23:01] <XXCoder> cnc wins quite quickly if you need to do more than onepart I'm sure.
[02:23:02] <zeeshan|2> well if you're really so persistent on wanting to do it manually
[02:23:04] <toastyde1th> it's easy on parts that are like, well, if i fuck this up who cares it's for my grandma's bingo drum
[02:23:13] <zeeshan|2> i load up a drill manually
[02:23:15] <zeeshan|2> dont even setup the Z
[02:23:30] <zeeshan|2> rapid to where i need to go to and manually plunge
[02:23:34] <toastyde1th> I'm not persistent, i'm reflecting on the fact I've cut metal for a living
[02:23:51] <toastyde1th> and looking at our cost/part for cnc vs manual depending on the operations and how complex they were
[02:24:16] <toastyde1th> and trying to figure out which i'd use for something simple like that if i only needed a few
[02:25:42] <zeeshan|2> http://i.imgur.com/HgejjYN.png
[02:26:10] <zeeshan|2> doing those 6 holes on the top view
[02:26:31] <zeeshan|2> i can put $100 on that ill beat a manual machinist on a cnc machine that im running manually :)
[02:26:47] -!- mozmck has quit [Read error: Connection reset by peer]
[02:26:49] <toastyde1th> that you're running manually? i'd also make that bet
[02:26:58] <toastyde1th> that I'm running manually? that part takes like 30 seconds on a drill press
[02:27:07] <zeeshan|2> no it doesnt :P
[02:27:12] <toastyde1th> okay!
[02:27:19] <zeeshan|2> ill give you a 100$
[02:27:24] <zeeshan|2> to make a video of you doing it in 30 seconds
[02:27:25] <toastyde1th> i take your superior experience and knowledge
[02:27:28] <XXCoder> 17 holes
[02:27:31] <zeeshan|2> no
[02:27:33] <zeeshan|2> juist the 6 holes
[02:27:34] <zeeshan|2> in 30 seconds
[02:27:37] <zeeshan|2> 100$ usd
[02:27:42] <zeeshan|2> make a video witha clock in it
[02:27:47] <zeeshan|2> otherwise stop talking shit
[02:27:48] <zeeshan|2> thanks :)
[02:27:53] <XXCoder> oh 6 holes thought you was counting all holes and blind holes
[02:27:55] <toastyde1th> and you've done what professionally?
[02:27:59] <zeeshan|2> they better be within .010
[02:28:08] <zeeshan|2> toastyde1th: youre not the only pro machinist here
[02:28:09] <Tom_itx> zeeshan|2 is defending his new found toy
[02:28:11] <zeeshan|2> im a pro engineer and machinst :)
[02:28:22] <Tom_itx> i'm bound to be a pro at something
[02:28:28] <zeeshan|2> and im a pro internet fighter
[02:28:37] <XXCoder> I'm pro on being crappy
[02:28:39] <zeeshan|2> and i challenge you!
[02:28:42] <toastyde1th> okay, i bow to your superior machining experience
[02:28:47] <zeeshan|2> good
[02:28:53] <zeeshan|2> now if you want to argue with me
[02:28:57] <Tom_itx> pfft
[02:29:00] <zeeshan|2> i expect a video showing those holes done in 30 seconds
[02:29:09] <zeeshan|2> with your master machinist skills on a manual machine
[02:29:20] <zeeshan|2> and ill be lenient and allow 30 thou variation of position
[02:29:23] <toastyde1th> it's not master machinig skills, it's something a first year apprentice learns to do
[02:29:25] <zeeshan|2> instead of the 10 thou this drawing calls for
[02:29:32] <toastyde1th> *machining
[02:29:33] <Tom_itx> toastyde1th i doubt you can scribe the holes and be as accurate as a cnc
[02:29:40] <zeeshan|2> yes so you should be able to make a 1004 bux fast.
[02:29:44] <zeeshan|2> 100$
[02:29:53] <zeeshan|2> its cheap money to be made in 30 seconds!
[02:29:54] <toastyde1th> Tom_itx, definitely not as accurate
[02:30:26] <zeeshan|2> i open up the challenge to everyone!
[02:30:28] <toastyde1th> how this whole thing got started is because I have routinely cut parts on manual machines because doing so was faster than cnc and we had the time/part to prove it
[02:30:32] <zeeshan|2> first one gets the 100 :D
[02:30:37] <toastyde1th> and was contemplating if i would be faster on a cnc or on a manual
[02:30:39] <toastyde1th> and now we're here
[02:30:43] <toastyde1th> with zeeshan pissing into the wind
[02:30:47] <zeeshan|2> im having fun
[02:30:55] <zeeshan|2> manual machinists are funny :)
[02:31:08] <XXCoder> zeeshan|2: trying to get someone else to quit channel eh
[02:31:19] <zeeshan|2> no
[02:31:22] <Tom_itx> cnc monkeys are funny too
[02:31:23] <zeeshan|2> he better not quit :{
[02:31:26] <toastyde1th> I'm not really sure what that means, "cnc machinist"
[02:31:30] <zeeshan|2> Tom_itx: i agree on that :P
[02:31:41] <toastyde1th> because everyone i worked with did both
[02:31:49] <zeeshan|2> i love how people try to argue manual machines anre superior to cnc machines
[02:31:57] <zeeshan|2> and their explanation is "i can turn dials faster"
[02:31:58] <toastyde1th> huh?
[02:31:59] <Tom_itx> A) they can't fix the program and B) they couldn't make it on a manual mill
[02:32:10] <zeeshan|2> my machinist buddy was saying it
[02:32:12] <toastyde1th> who is saying one is superior to the other?
[02:32:18] <zeeshan|2> then im like dude "type g0 x y"
[02:32:20] <Tom_itx> zeeshan|2 seems to be
[02:32:21] <zeeshan|2> you're in position.
[02:33:06] <toastyde1th> you pick the goddamn right tool for the job, and if my data shows that my manual side of the shop cuts the part faster for a specfic population of parts, then i use the manual side of the shop because it's cheaper
[02:33:24] <toastyde1th> i'm not sure what that has to do with one being somehow better
[02:33:30] <zeeshan|2> how is a manual any different than a cnc?
[02:33:35] <zeeshan|2> you can literally use the mdi
[02:33:40] <zeeshan|2> to do exactly what the manual guy is doing
[02:33:45] <Tom_itx> the monkey behind the wheel
[02:33:47] <MrSunshine> i like the little argument that "you need to draw it up on the computer" also .. then the "manual machinist" goes to his dykem? gets his scales, his scribes and punches then sits down for half an hour doing layout work :P
[02:33:48] <zeeshan|2> and you can do it a lot better by providing an exact feedrate
[02:33:57] <zeeshan|2> there is no comparison.
[02:34:12] <toastyde1th> okay, except there is a comparison, and that's time per part
[02:34:15] <toastyde1th> at a given scrap rate
[02:34:22] <toastyde1th> that is literally how machine shops operate
[02:34:28] <Tom_itx> for one part it's hardly worth a cnc unless it's a very complex part
[02:34:29] <zeeshan|2> the only things i can possibly think of that makes a manual desriable is cost of machine, cost of maintenance, less skill required
[02:34:41] <toastyde1th> oh man you're a huge moron
[02:34:42] <toastyde1th> i get it
[02:34:43] <zeeshan|2> Tom_itx: if you were to only have one machine at your shop
[02:34:44] <toastyde1th> sorry
[02:34:48] <zeeshan|2> which one would it be?
[02:34:50] <zeeshan|2> manual? or cnc
[02:34:56] <zeeshan|2> cnc does everything a manual can.

[02:35:05] <zeeshan|2> instead of handles, you got a joystick
[02:35:14] <toastyde1th> you need to get more experience machining
[02:35:16] <zeeshan|2> and if you really want to make something complex, run g-code.
[02:35:18] <toastyde1th> is about all i can say now
[02:35:23] <zeeshan|2> toastyde1th: ive got 10 years
[02:35:29] <Tom_itx> zeeshan|2 i can't make that choice
[02:35:30] <zeeshan|2> good try
[02:35:33] <toastyde1th> running a hacksaw doesn't count
[02:35:48] <zeeshan|2> im suprised i make toastyde1th so mad
[02:35:49] <zeeshan|2> :-)
[02:35:57] <toastyde1th> you don't, i'm flabbergasted you're so naive
[02:36:01] <Tom_itx> heh
[02:36:16] <zeeshan|2> Tom_itx: why not
[02:36:19] <Tom_itx> i did test specimens on a manual but i also did them on a cnc
[02:36:33] <Tom_itx> it made no difference to me really
[02:36:43] <Tom_itx> but for some parts, you can't make them on a manual machine
[02:36:52] <zeeshan|2> you can
[02:36:55] <zeeshan|2> you only need a rotary table
[02:36:59] <zeeshan|2> and you gotta offset the part 10 times.
[02:37:01] <zeeshan|2> :)
[02:37:08] <Tom_itx> but for others it's more cost effective to use a cnc
[02:37:42] <zeeshan|2> Tom_itx: i have a couple of friends that run machine shops
[02:37:55] <Tom_itx> i would _prefer_ a cnc because i like programming
[02:37:55] <MrSunshine> and the most awesome thing with cnc is that after youve made the first part .. you can make another one alot faster :P
[02:37:56] <zeeshan|2> their manual mill sees little to no use
[02:38:01] <MrSunshine> that is the same
[02:38:05] <zeeshan|2> MrSunshine: thats true
[02:38:11] <Tom_itx> but if all i could have was a knee mill i'd be delighted
[02:38:13] <zeeshan|2> but im trying to explain that instead of handles you have mdi
[02:38:21] <zeeshan|2> you can do the exact same thing faster than a manual machine
[02:38:28] <zeeshan|2> cause if you've ever turned dials, you'll know it sucks.
[02:38:35] <zeeshan|2> if you have a dro, its a bit better, but you'll still overshoot
[02:38:39] <zeeshan|2> and try to get back into position
[02:38:44] <Tom_itx> zeeshan|2, you can't _feel_ the machine with mdi buttons
[02:38:48] <zeeshan|2> cnc doesnt have that prob
[02:38:50] <Tom_itx> and sometimes you need to feel it
[02:38:56] <zeeshan|2> Tom_itx: that is one of the most reasonable complaints
[02:39:00] <toastyde1th> zeeshan is being a willfull idiot at this point
[02:39:06] <toastyde1th> i wouldn't spend too much time engaging the argument
[02:39:08] <zeeshan|2> but you rely more on noise
[02:39:14] <Tom_itx> toastyde1th, fuel the fire
[02:39:25] <zeeshan|2> i made toastyde1th so mad

[04:46:03] <Erant> Well, that end mill didn't last nearly as long as I'd hoped...
[04:46:26] <XXCoder> Erant: how long did it last and what material
[04:51:25] <Erant> I was cutting aluminum, removed something along the lines of 15 cubic inches of material.
[04:51:38] <Erant> I have a feeling I may have just been a little rough with it
[04:52:02] <Erant> It still cuts, just at like half the speed of a sharp one, with a bunch of chatter and hot chips.
[04:52:39] <Erant> Throws up burrs left and right.
[04:52:59] <XXCoder> cutting alim tools should last quite a long while
[04:55:25] <toastyde1th> Erant, what's your chip load?
[04:55:41] -!- xreal has quit [Quit: Verlassend.]
[04:58:21] <Erant> Euh, lemme math for a sec.
[04:59:24] <Erant> 0.004in/tooth
[04:59:34] <toastyde1th> strange
[04:59:41] <toastyde1th> number of flutes?
[04:59:55] <Erant> Actually, maybe more like 0.002
[05:00:03] <Erant> 2 flute 3/8" cutter.
[05:00:11] <toastyde1th> were you slotting?
[05:00:18] <Erant> Yah
[05:00:29] <toastyde1th> two things could be causing this
[05:00:34] <toastyde1th> .002 is a rather light chip load
[05:00:35] <XXCoder> slotting is pretty stressful?
[05:00:43] <Erant> It's full WOC
[05:01:00] <toastyde1th> personally i would recommend you slow the rpm of the endmill down
[05:01:06] <toastyde1th> and try to get the chip load up
[05:01:24] <toastyde1th> next, slotting needs to have chip clearance - you have to have something removing the chips
[05:01:40] <Erant> Right, I've got a vacuum sucking them out.
[05:01:49] <toastyde1th> usually doesn't do the trick
[05:02:10] <XXCoder> toasty, I saw a video doing different with slots, the tool (which is little smaller than cut slot size) moves in circles as it moves forward
[05:02:28] <XXCoder> basically circles with moving center
[05:02:34] <toastyde1th> i recommend using air if you can, because what you need to do is get the chips out from the back end of the cutter
[05:02:56] <toastyde1th> they stick to the cutter and as it comes around again, get wedged between the work and the cutter and that dulls it
[05:03:02] <toastyde1th> thinner chips are more prone to this
[05:03:18] <toastyde1th> and yeah, that circular "bite" is how a good cnc toolpath will avoid recutting chips
[05:03:59] <toastyde1th> i would recommend around .007" chip load per tooth
[05:04:23] <toastyde1th> and if that is going too fast for your machine, slow the spindle and feed rate down to maintain that .007 until it cuts nicelyt
[05:04:30] <toastyde1th> blow air right behind the endmill
[05:04:37] <Erant> I have a slightly less rigid machine, so I'm not sure how well a 0.007" chip load will work...
[05:04:43] <Erant> But I'll give that a shot.
[05:04:50] <toastyde1th> generally it does not stress the machine out
[05:04:57] <toastyde1th> go slow, but take heavy chip loads.
[05:05:11] <toastyde1th> the hp/torque is not a function of chip load
[05:05:35] <toastyde1th> (actually taking a big chip reduces the amount of power required)
[05:06:14] <toastyde1th> another more annoying trick is to keep your slotting passes shallow
[05:06:53] <toastyde1th> anything over .100 is actually quite a big load for a 3/8th endmill
[05:06:57] <toastyde1th> (.100 deep)
[05:07:08] <Erant> I run 'm at 0.05"
[05:07:14] <toastyde1th> excellent
[05:07:55] <anomynous> i usually slot at about 0.5*dia
[05:08:02] <Erant> k, I'll give the low RPMs a shot, see if the thing makes any crunchy sounds. :)
[05:08:10] <toastyde1th> it's going to make a lot more noise
[05:08:29] <toastyde1th> that is not actually a problem, you just can't hear the sound higher speeds make
[05:08:55] <toastyde1th> another, great trick is to use a roughing endmill for slotting
[05:08:59] <toastyde1th> they tolrate nonsense a lot better
[05:09:18] <XXCoder> corncob?
[05:09:21] <XXCoder> or too much?
[05:09:28] <toastyde1th> corncob, yes - same thing
[05:09:44] <Erant> 2 flute or 3 flute?
[05:09:47] <toastyde1th> they have two advantages, one they let you take huge chip loads that you wouldn't be able to take normally
[05:09:51] <toastyde1th> and their metallurgy is different
[05:09:59] <toastyde1th> they are much duller, but highly shock resistant
[05:10:03] <toastyde1th> ductile, almost
[05:10:11] <toastyde1th> either one works for slotting
[05:10:14] <toastyde1th> 2 vs 3
[05:10:24] <toastyde1th> the canonical answer is 2 flute is better for a full slot
[05:10:43] <toastyde1th> but i have found that to be wrong just as often as it helps
[05:10:55] <toastyde1th> 3 flute will reduce chatter
[05:11:06] <toastyde1th> 2 flute causes less deflection and has better chip clearance
[05:11:23] <toastyde1th> 3 flute also requires much lower gearing if you're power/rigidity limited
[05:11:29] <toastyde1th> and that can be an issue in small machines
[05:12:12] <Erant> I have a brushless spindle, no gearing in my drive train.
[05:12:21] <toastyde1th> then definitely stick with two
[05:12:38] <toastyde1th> corncob/roughing mills are also going to be a savior for you
[05:13:39] <toastyde1th> they're designed so that at each depth, only one flute on the endmill is cutting that part of the metal
[05:14:02] <toastyde1th> so with a 2 flute endmill, if you have a .005" chip load, you will have close to a .010" chip load on the rougher
[05:14:07] <toastyde1th> much lower power consumption
[05:14:24] <toastyde1th> (and thus less torque on the drivetrain and axis drives)
[05:14:40] <Erant> Any recommended places to get 'm? eBay seems to mostly have 3-4 flute ones...
[05:14:57] <toastyde1th> unfortunately not, I have not been in a machine shop in quite some time
[05:15:19] <toastyde1th> although i'll say people in here and on the hobby forums are great resources
[05:15:24] <toastyde1th> for finding tool vendors
[05:15:30] <anomynous> mm... im not an expert, but bigger your chipload, the more material you remove per some distance cutter edge is in material. And with slow enough speed your cutter doesn't dull too fast. But if your chipload is too big your cutting edges could break you might not meet tolerances you want to. :U
[05:15:33] <Erant> Fair enough. I've got a few places to look still.
[05:16:07] <toastyde1th> anomynous, it's never the cutter edge that breaks, cutters break up where the flutes terminate
[05:16:18] <toastyde1th> if you have an edge failure it's 99% of the time heat related
[05:16:24] <toastyde1th> or a chip recutting issue
[05:16:39] <anomynous> thanks
[05:16:58] <Erant> I check heat relatively frequently. The cutter's never hot, the chips can be quite hot though.
[05:17:09] <toastyde1th> you don't really have to worry about heat in aluminum
[05:17:25] <toastyde1th> ~700 sfm in a non-slotting cut is about the maximum for HSS tooling
[05:17:37] <toastyde1th> for carbide... however fast the machine will spin.
[05:17:51] <anomynous> if you have cooling and dont melt aluminium around the cutter
[05:18:14] <toastyde1th> the faster you go the more heat stays in the chips, so you don't actually need cooling
[05:18:29] <Erant> Looks like roughing mills don't really seem to come in 2 flute.
[05:18:33] <toastyde1th> (for aluminum)
[05:18:47] <toastyde1th> I'd try the heavier chip load first
[05:18:54] <toastyde1th> and if that fails, go to a 4 flute and see what happens
[05:19:00] <toastyde1th> (4 flute rougher)
[05:19:00] <anomynous> want a pic on alumium dipped carbide endmill? :D
[05:19:31] <toastyde1th> anomynous, i routinely cut aluminum w/ a 5" diameter plain carbide insert facemill at 6k rpm
[05:19:58] <toastyde1th> .300 depth of cut, 4" feed over
[05:20:19] <anomynous> it also depends on alumium alloy
[05:20:24] <anomynous> 7k series you can cut fast
[05:20:26] <anomynous> 6k can melt
[05:20:28] <toastyde1th> it really doesn't
[05:20:38] <Erant> I ran a 4 flute end mill at 20IPM @ 2.5k RPM after I discovered that my 2 flute was dull. Ripped through much faster than what I've done before.
[05:21:08] <Erant> No chatter, clean cuts.
[05:21:25] <toastyde1th> yeah, small cutter diameters are a bit of a clusterfuck unfortunately
[05:22:09] <Erant> Right. 3/8" is my 'workhorse'. I can do 1/2" cutters, but...
[05:23:21] <Erant> TiCN give me anything?
[05:23:30] <anomynous> well... https://www.anony.ws/image/JuLd
[05:23:31] <toastyde1th> not at the speeds you're likely to be running
[05:23:50] <toastyde1th> anomynous, that's the result of chip recutting and ejection, not speed
[05:23:56] <toastyde1th> you can do that (and I have) at 100 rpm
[05:24:23] <Erant> anomynous: Aluminum popsicle!
[05:24:30] <anomynous> Erant, yea ;D
[05:24:58] <toastyde1th> TiCN is a solid lubricant, so when you run the cutter hot enough to melt the aluminum at the cutting face, it kinda sizzles and slides like water on a hot pan
[05:25:21] <toastyde1th> very very nice at high speeds because the chips completely fly off the cutter and you don't need any chip flushing
[05:25:36] <Erant> Ah, yeah. Useless to me.
[05:25:38] <toastyde1th> for low speeds, you're better off with polished endmills
[05:25:52] <toastyde1th> because the welding effect is mostly surface adhesion and is not a real metal-metal bond
[05:26:27] <Erant> Probably get this guy: http://www.ebay.com/itm/3-8-3-Flute-Cobalt-CP-35-Helix-Roughing-End-Mill-For-Aluminum-Melin-USA-15638-/310989501189?hash=item48686b3305:m:mZUSR1N5Rd6rljKuZcg6BGQ
[05:26:41] <toastyde1th> yeeaaah boyeee, that's the ticket
[05:26:51] <toastyde1th> definitely give that one a try
[05:26:52] <Erant> Along with some regular 2 flutes.
[05:27:41] <toastyde1th> play around with lower speeds and bigger endmills if you can - not now, but in the future
[05:27:57] <toastyde1th> a big big mistake people make is to see the SFM reccomendations for a cutter/material and try to hit it
[05:28:05] <toastyde1th> the sfm recommendation is a maximum
[05:28:31] <toastyde1th> especially in roughing, you want that end mill rotating as slow as you can get it without losing torque from your motor
[05:28:39] <XXCoder> that cnc tool calculator says it tries to find best sweet spot but dunno
[05:29:00] <toastyde1th> imo those are all bullshit
[05:29:21] <Erant> toastyde1th: Slight advantage with the brushless is that it has a flat torque profile.

[05:30:36] <toastyde1th> yeah, definitely preferable to the alternative
[05:31:10] <toastyde1th> there is a book by Sandvik
[05:31:14] <toastyde1th> "Modern Metal Cutting"
[05:31:24] <toastyde1th> it is basically an introduction to cutting physics, and I strongly recommend it
[05:31:30] <toastyde1th> hard to find though
[05:32:48] <Erant> I'll try to track it down, my gut feel is probably not the right one 95% of the time.
[05:32:56] <Erant> "More RPMs must be better"
[05:33:20] <toastyde1th> there's too much that can go wrong, too many variables to have a quick and easy calculator
[05:33:30] <toastyde1th> you CAN calculate this stuff but the equations are... large.

[05:56:15] <XXCoder> yeah
[05:56:20] <toastyde1th> the only issue you really have to worry about is burning the stuff from lack of feed rate, in my experience
[05:56:47] <XXCoder> not much I can do about 27000 rpm lol so I guess I would need pretty fast ipm
[05:56:53] <toastyde1th> and for the love of god not using an endmill
[05:57:09] <toastyde1th> yeah, routers move fast, but you do not need a huge chip load
[05:57:23] <toastyde1th> router bits have so much rake they don't care much about a light chip load - they'll shave it off just fine
[05:57:50] <toastyde1th> beyond that... *shrug*
[05:58:01] <toastyde1th> but yeah, 60-150 IPM are common feed rates
[05:58:13] <toastyde1th> single flute cutters are a godsend on that
[05:58:20] <toastyde1th> they'll let you half your feed rate
[05:58:42] <XXCoder> I find it a little odd that machine file is configured using inches per second but maching gcode is inches per minute
[05:59:04] <XXCoder> thats good to know. I think all my initial tools are 2 flute which should be great
[05:59:12] <toastyde1th> no idea, there are many things I've bitched about on how linuxcnc does things
[05:59:20] <toastyde1th> but i'm not in the club, so it doesn't really matter
[05:59:26] <XXCoder> me either
[05:59:40] <XXCoder> bleh looks like I have to return tablet I bought to store
[05:59:45] <toastyde1th> :o
[05:59:47] <toastyde1th> what happened?
[05:59:52] <XXCoder> 1/2 inch on right edge dont respond
[06:00:19] <toastyde1th> ouch
[06:00:41] <XXCoder> yeah
[06:00:48] <XXCoder> jhopefully next will be better
[06:00:58] <XXCoder> its pretty rare tablet that has hdmi out, and gps!
[06:01:03] <XXCoder> and sub-$200
[06:01:17] <XXCoder> (and not no-name even!)
[06:01:22] <toastyde1th> hahahaha
[06:01:24] <toastyde1th> what is it
[06:01:39] <XXCoder> acer iconia 8
[06:02:08] <toastyde1th> strange problem to have from acer
[06:02:27] <XXCoder> yeah
[06:02:32] <XXCoder> I suspect its sport error
[06:02:39] <XXCoder> someone faled to connect properly
[06:03:38] <toastyde1th> i keep wanting to like tablets but i never find a use for them =(
[06:04:02] <XXCoder> I dont really have major use for em but they do come in handy sometimes
[06:04:10] <XXCoder> thats why it must be sub-$200
[06:05:20] <toastyde1th> this is unrelated, but do you do 3d printing
[06:10:12] <XXCoder> I want to.
[06:10:51] <toastyde1th> i am looking around at pre-assembled kits
[06:11:02] <toastyde1th> also unassembled kits but the instructions seem absurd
[06:11:43] <XXCoder> from what I see
[06:11:51] <XXCoder> if you can build machine, its pretty simple
[06:12:07] <XXCoder> height seems to matter the most
[06:12:09] <toastyde1th> I was hoping that's the case, and it's difficult to assess the skill level of some of these reviewers
[06:12:28] <XXCoder> so say 1 footx1 foot x 3 feet high can handle pretty much anything
[06:12:40] <toastyde1th> yeah, that's about the envelope I was looking for
[06:12:51] <toastyde1th> trying to build parts trays and some assorted labratory gear
[06:12:59] <XXCoder> I wonder if I could just add printer head to my cnc router
[06:13:11] <toastyde1th> that's a huge gripe i have with the 3d printer movement
[06:13:16] <toastyde1th> everyone's doing their own goddamn machine control
[06:13:18] <XXCoder> and if need longer just do horzional
[06:13:41] <toastyde1th> there seems to be little to no reason not to use g-code as the data format and compile parts to that
[06:13:45] <toastyde1th> and yet
[06:14:06] <toastyde1th> one of the major advantages I see in doing things like using a cnc control is the ability to print 5 axis parts
[06:14:14] <toastyde1th> i.e. adding material to existing things as well as printing without supports
[06:14:15] <XXCoder> I want to modify gcode standard to one old fadal uses. in least one aspect
[06:14:24] <XXCoder> why? because E1 to E99 is awesome
[06:14:33] <XXCoder> coordities. not g54 to 59
[06:14:42] <toastyde1th> i have stayed far away from fadal, what is e**
[06:14:49] <XXCoder> coordites
[06:14:56] <toastyde1th> just.. work coordinates?
[06:15:07] <XXCoder> yeah, but then its VERY readable
[06:15:20] <XXCoder> okuma is.. just weird. g15h**
[06:15:24] <toastyde1th> most machines use g54.xx
[06:15:31] <toastyde1th> they still support 54 to 59
[06:15:47] <XXCoder> yeah I'd keep that both for backward comitability
[06:16:41] <toastyde1th> fanuc's modern controls are insane
[06:16:48] <toastyde1th> they support almost APT-like commands
[06:17:01] <XXCoder> apt-get install mill?
[06:17:03] <XXCoder> :P
[06:17:05] <toastyde1th> hahaha
[06:17:07] <toastyde1th> poof
[06:17:08] <toastyde1th> cnc mill
[06:17:32] <toastyde1th> you can define polygons and points
[06:17:46] <toastyde1th> and then tell the machine to to face down to it, pocket it, then drill at a list of points
[06:17:50] <XXCoder> nice
[06:17:57] <toastyde1th> so if you have like, heat sink fins, all you need are lines
[06:18:06] <toastyde1th> and the machine can be told to stay away whatever distance from the line
[06:18:36] <toastyde1th> easily the best implementation of hybrid g-code and conversational I've seen
[06:18:57] <XXCoder> interesting
[06:19:04] <toastyde1th> it has a library/code reference right on the screen, and if you pick a command, you can input each parameter and it will tell you what it does
[06:19:20] <toastyde1th> then plop it at your cursor's position
[06:19:56] <toastyde1th> the reverse is also true - you don't know what a line does, and swap into conversational, and it will have the reference and the parameter list
[06:20:12] <toastyde1th> as well as a little plot of what the toolpath is
[06:20:56] <XXCoder> nice indeed
[06:20:57] -!- ve7it has quit [Remote host closed the connection]
[06:21:10] <XXCoder> I really need cam that is basically free lol
[06:21:17] <XXCoder> freecad has it, but its hard one
[06:21:21] <toastyde1th> that, i think, is the fault of the reprap community
[06:21:25] <toastyde1th> that right there
[06:21:28] <toastyde1th> that there is no good cam
[06:21:38] <toastyde1th> we have freecad and librecad
[06:21:52] <toastyde1th> we have a machine control
[06:22:28] <toastyde1th> and instead of filling that gap with a CAM program with a toolpath for 3d printing and leaving the hooks open for other types of solutions, everyone does their own, insular thing
[06:22:35] <toastyde1th> so even though it's open source... it's all islands
[06:22:56] <toastyde1th> i am not a fan of the maker movement, as you can probably tell
[06:23:07] <XXCoder> its cool in some ways but yeah
[06:23:13] <XXCoder> need more work together
[06:23:23] <XXCoder> not special clubs
[06:23:46] <XXCoder> librecad seems nice
[06:23:49] <XXCoder> 2d cad
[06:23:51] <toastyde1th> yeah
[06:24:01] <toastyde1th> strongly prefer librecad to freecad
[06:24:09] <XXCoder> no 3d though
[06:24:28] <toastyde1th> yeah, but the interface is well done
[06:24:35] <toastyde1th> versus freecad, which is... yeah.
[06:24:55] <XXCoder> freecad sketch I love
[06:25:23] <toastyde1th> i really loved how pro/e used to do things, back when it was pro/e
[06:25:38] <toastyde1th> steep learning curve but holy shit
[06:26:43] <toastyde1th> though i haven't tried freecad recently
[06:26:47] <toastyde1th> so maybe i should look again

[06:28:17] <XXCoder> get 0.16
[06:28:20] <XXCoder> hella good
[06:28:54] <toastyde1th> i mean i'll definitely be using it one way or the other if i do this 3d thing
[06:29:01] <toastyde1th> which i am still on the fence about :D
[06:29:42] <FAalbers> Did my very firs surface cut :) ... https://dl.dropboxusercontent.com/u/2338658/CNC_Surfacetest.jpg
[06:30:02] <toastyde1th> congrats!
[06:30:06] <XXCoder> woot!
[06:30:08] <XXCoder> congats!
[06:30:29] <XXCoder> so thats single axle pass?
[06:30:58] <XXCoder> basically do rows across say X
[06:31:15] <FAalbers> Did X and Y
[06:31:27] <FAalbers> Bit first I cout out in rough
[06:31:32] <FAalbers> But
[06:32:05] <FAalbers> x and y final wilth ball bit
[06:32:50] <FAalbers> Actually did X and Y with a endmill , then only x with ball bit
[06:33:00] <FAalbers> 1/8
[06:33:31] <XXCoder> reason i asked is because I see little bit of cross ribs
[06:33:40] <XXCoder> expecially in curvy spots
[06:33:45] <FAalbers> Somehow when I started with the ball bit on y , which was following the grain, it was messing it up a bit , so I stopped it
[06:34:21] <FAalbers> XXCoder, YEah . That's from the x and y pass with endmill
[06:34:31] <XXCoder> cool
[06:34:38] <XXCoder> its very good for first try!
[06:36:33] <FAalbers> Thanks , the wood was way too soft though. It was flurring up, The ball bit nicely cut of all that fluring up

[07:47:30] <CaptHindsight> toastyde1th: hobby 3D printing is a fragmented bunch of near worthless toy machines with very limited materials
[07:47:41] <toastyde1th> CaptHindsight, agreed
[07:48:04] <toastyde1th> but i still have a rack of projects where that sort of thing is exactly what I need
[07:48:11] <XXCoder> yeah there is many many weird machines
[07:48:32] <CaptHindsight> I've been tinkering a bit after 3 years with Marlin and Creation Workshop on a duino for someone...
[07:48:49] <toastyde1th> inexpensive custom clamps, parts trays, holders for experimental equipment
[07:49:01] <toastyde1th> cases for projects
[07:49:03] <CaptHindsight> it a f***ingmess even now
[07:49:18] <XXCoder> got question though
[07:49:26] <XXCoder> how do you design a case for board?
[07:49:28] <toastyde1th> the general idea is to print the basic parts, anneal it, cut the parts of it that are critical, then vapor polish
[07:49:29] <toastyde1th> and paint
[07:49:46] <toastyde1th> XXCoder, what do you mean
[07:49:58] <CaptHindsight> they keep patching their code to add more features that they never imagined they would need
[07:49:59] <XXCoder> I has a tb6560 but no case for it
[07:50:08] <XXCoder> I plan to make one for it
[07:50:13] <toastyde1th> take the dimensions of the board
[07:50:18] <XXCoder> but got no idea how to design one.
[07:50:38] <toastyde1th> a lot of people are just measuring the through holes on boards, and printing bungs for screws
[07:51:20] <toastyde1th> it's plastic so it's also fairly easy to work by hand if you need accurate holes, etc
[07:51:25] <CaptHindsight> XXCoder: you have to work around the mounting holes for the board, the connector locations and combine that with aesthetics...
[07:51:56] <CaptHindsight> you might also have to factor in thermal management
[07:52:04] <toastyde1th> fans!
[07:52:56] <XXCoder> ok
[07:53:04] <CaptHindsight> fans, heat spreaders, vents, etc
[07:53:04] <XXCoder> right now its in cardboard case lol
[07:53:42] <toastyde1th> here is an example of a 3d printed case
[07:53:42] <toastyde1th> http://openqcm.com/design
[07:53:48] <toastyde1th> for an actual bit of equipment
[07:54:08] <toastyde1th> goodnight all!
[07:54:14] <XXCoder> night
[07:55:24] <CaptHindsight> XXCoder: I was going to 3D print (SLA) laptop cases
[07:55:33] <CaptHindsight> http://openlunchbox.com/smf/index.php?topic=35.0
[07:55:35] <XXCoder> laptop case?
[07:55:51] <XXCoder> interesting
[07:56:18] <CaptHindsight> no real point to the project anymore since even AMD closed all their firmware
[07:56:51] <XXCoder> aw
[07:57:02] <XXCoder> you can make one with CHiP or raspberrypi
[07:57:32] <CaptHindsight> was going to use thermally conductive engineering photopolymer
[07:57:51] <CaptHindsight> it's similar to thermally conductive ABS
[07:58:23] <CaptHindsight> https://www.kickstarter.com/projects/pine64/pine-a64-first-15-64-bit-single-board-super-comput?ref=category
[07:59:25] <CaptHindsight> $15 64-Bit Single Board Super Computer.... that actually costs more if you want it to do anything
[07:59:36] <XXCoder> we are getting close to universal computing
[08:00:37] <XXCoder> $19 has lot more stuff
[08:00:40] <XXCoder> including camera
[08:00:53] <CaptHindsight> at extra cost
[08:01:12] <XXCoder> still no screen
[08:02:26] <XXCoder> $19 touchpad apparently is a screen
[08:02:34] <XXCoder> so guess $19 is minium
[08:03:09] <CaptHindsight> hasta banana
[08:04:05] <XXCoder> anyway
[08:04:11] <XXCoder> CHiP is fine for me lol
[08:04:22] <XXCoder> it comes with RGA out so I plan to use it with projector
[08:06:41] <XXCoder> chip fails on google test so suggest just do chip kickstarter to find it

[11:06:07] <trentster> omg - This i have never seen before, I must have messed up a setting for feed rate in fusion 360, I was pocketing a 90mm x 6mm slot 6mm deep at 0.5 doc. The machien flew into it and did the entire slot in about 20 seconds - I am not kidding I am never seen flying chips with smoke trails before. I was busy dodging them in a panic.
[11:06:34] <XXCoder> fast.
[11:06:42] <trentster> Weird thing was it finished slot was cut pretty cleanly - no heat on part and endmill is still fine
[11:06:44] <XXCoder> did tool break?
[11:06:48] <trentster> I was freaking out tho!
[11:06:52] <XXCoder> wow got lucky
[11:07:02] <trentster> gonna go and see wtf I did wrong
[11:07:39] <trentster> btw this was with a 1/8 carbide endmill
[11:07:42] <XXCoder> 1000 ipm heh
[11:07:48] <trentster> these things normally snap like toothpicks
[11:08:11] <trentster> maybe it was bad interpretation of the gcode
[11:08:14] <trentster> let me paste it
[11:09:36] <XXCoder> ok
[11:09:52] <trentster> https://gist.github.com/trentster/d81fe4dc5ed02e2adc9c
[11:10:08] <XXCoder> what line number is pocket?
[11:10:20] <trentster> the whole thing is a pocket
[11:10:26] <XXCoder> oh ok
[11:10:28] <trentster> I am busy testing some cuts
[11:10:57] <XXCoder> F4210.71
[11:11:04] <XXCoder> 4210 mm a minute?
[11:11:19] <XXCoder> thats 4 meters a minute
[11:11:19] <trentster> it was meant to be 30IPM lol!
[11:11:25] <trentster> I cant believe it worked
[11:11:49] <XXCoder> it repeats a lot.
[11:12:01] <XXCoder> why would it need to repeatly set feed speed?
[11:12:08] <trentster> Thats how Fusion360 spat it out
[11:12:14] <XXCoder> oh yeah g0 then g1 againb
[11:12:22] <XXCoder> g1 would need f again
[11:12:52] <trentster> I was literally dodging these smoking projectiles coming off the cutter.
[11:13:00] <XXCoder> damn
[11:13:09] <XXCoder> calculate chip size?
[11:13:17] <XXCoder> I bet its riciously large
[11:13:43] <trentster> haha so now that I saw that - I guess 30IPM may be too conservative
[11:13:46] <trentster> :P
[11:14:10] <XXCoder> maybe so but suggest closer look at tool
[11:14:27] <trentster> you think it may be damaged,
[11:14:54] <trentster> I broke 3 yesterday playing around - mainly too slow feed rates or too deep doc
[11:15:22] <trentster> these are the cheapie chinese carbides, they have done a ton of cutting for me in the past
[11:15:30] <XXCoder> tool may look fine but chip may be all kind chips on it
[11:16:13] <trentster> I will take the bit out and replace it anyway - will bring it back into the house and look at the cutting edge with a microscope.
[11:16:17] <trentster> would be insteresting
[11:16:38] <XXCoder> you can feel it using fingernail though
[11:16:46] <XXCoder> it should be smooth and "sharp"
[11:18:19] <trentster> interesting - this is what must have happened I think I may have swapped out the tool fgrom imperail to metric and just forgotten to re-check the feeds and speeds

[11:57:45] <trentster> I just watched a few minutes of a training video while reading the captions - its 100% accurate
[11:57:54] <XXCoder> freecad tutorials are amazing but a mess
[11:58:12] <XXCoder> and few tutorials are broken because of changes
[11:58:22] <trentster> bah freecad!
[11:58:39] <trentster> use Fusion mate - its a better world
[11:58:53] <XXCoder> ok lol has linux edition?
[11:59:29] <trentster> its cloud based - your files get stored in the cloud - so essentially you could use it from any device
[11:59:37] <trentster> it does install a local client tho.
[11:59:44] <XXCoder> oh
[12:00:01] <XXCoder> it does mean they can access designs
[12:00:10] <XXCoder> so no secret designs
[12:00:52] <trentster> I think their strategy is to get folks using it and becoming proficient then when they move into careers in design and manafacture they will continue to use it. A big revenue for them longterm as well is you can buy credits for distributed rendering in the cloud
[12:01:06] <trentster> very important for people doing rapid prototyping etc
[12:01:24] <XXCoder> so cloud is basically free as long as below certain amount of profit
[12:01:42] <trentster> XXCoder: I dunno about that, I have not gone down the privacy rabbit hole yet

[14:35:20] <Deejay> hrhr
[14:35:28] <FinboySlick> ZATK: What sort of mill are you looking to buy?
[14:35:48] <gonzo_> unless it is my bridgeport, which was tons of scrap
[14:35:51] <ZATK> Metaal milling
[14:36:23] <ZATK> I'm fine with small work area
[14:36:23] <gonzo_> industrial size/table top. Steel/ali
[14:36:54] <gonzo_> production/hobby/prototype?
[14:37:11] <ZATK> hobby steel
[14:37:20] <ZATK> that possible
[14:39:09] <gonzo_> cnc'ed or retro fit?
[14:40:25] <ZATK> what is the difference
[14:40:40] <gregncnc> turnkey or DIY?
[14:41:00] <gonzo_> do you need one that is built for cnc, or you want a project to do that retro fit?
[14:41:20] -!- chris_99 [chris_99!~chris_99@unaffiliated/chris-99/x-3062929] has joined #linuxcnc
[14:41:30] <gonzo_> (I'm not the one to advise oin a mill, but I know the questions that need to be asked)
[14:41:34] <ZATK> You talking about having to upgrade it for CNC
[14:41:51] <gonzo_> yep
[14:41:58] <ZATK> I'm fine with tat
[14:42:00] <ZATK> that
[14:42:41] <FinboySlick> ZATK: What's your budget?
[14:43:03] <ZATK> 1k. But I just want to buy the mill now
[14:43:03] <FinboySlick> There isn't much of a used market for the smaller mills.
[14:43:18] <gonzo_> my personal suggestion would be get at bench top manual mill. And do a retro fit. As you can use it manually to make the bits to convert it. And learn to mill at the same time.
[14:43:29] <ZATK> I would like to spend the least possible
[14:43:32] <FinboySlick> 1k is going to be tight.
[14:44:00] <ZATK> I ebay mills and find a lot at 4k and 300
[14:44:22] <ZATK> the price range seems larger
[14:44:29] <ZATK> then I thought
[14:44:53] <gonzo_> in the UK, somethimng like the clarke/axminster/etc hobby mill. OK, leadscrews and ways are sloppy
[14:44:59] <ZATK> I also don't know what I should be looking for to tell if a system is powerful enough
[14:45:09] <gonzo_> but the screws could be replaced as you retro fit it
[14:45:25] <gonzo_> suspect there are better startiong points. But those are available easilly
[14:45:26] <FinboySlick> gonzo_: He'd bust his 1k budget though.
[14:45:45] <gonzo_> used they go for 600-700£
[14:46:15] <FinboySlick> Well, if we're talking 1k£, that's a bit more like 2k in Canadian pesos.
[14:47:02] <ZATK> I want to make 3d printer parts
[14:47:15] <ZATK> anyone do that here
[14:47:41] <gregncnc> parts are parts, the question is how many will you make
[14:49:17] <ZATK> why does that change things. I'm hoping that after I make my parts I still have a mill and not a piece of junk
[14:52:07] <SpeedEvil> If you're wanting to make 1000, workarounds that are fine for one may not be
[14:52:30] <gregncnc> It depends on what you're doing. The more parts you intend to make, it makes sense to invest more initially.
[14:53:06] <SpeedEvil> For one, a good file, and a caliper may be quite adequate.
[14:57:22] <ZATK> I want to start a small business not a empire
[14:57:50] <gregncnc> The more complicated the parts get, with tool changes, tapping, etc, you would like to have these initially to save time.
[14:57:52] <ZATK> So in my mind I can start with small equipment the upgrade when needed
[14:57:56] <gregncnc> Time is your biggest expense
[14:58:37] <SpeedEvil> depending on if it is.
[14:59:04] <SpeedEvil> If you're making one thing a day, then you can in principle do a lot of hand-fiddling.
[14:59:23] <SpeedEvil> Twenty, and even if you can actually physically do it - it's going to get a lot more annoying a lot faster
[14:59:35] <gregncnc> If you can get paid a good shop rate to file that's fine

[15:02:33] <FinboySlick> ZATK: If you can design your part not to require any tool changes, your requirements go down.
[15:02:44] <FinboySlick> ZATK: But you limit yourself on the design.
[15:03:51] <ZATK> Yea something to think about
[15:06:49] <FinboySlick> Not having a reliable tool change mechanism sort of bit me on the one little production run I had to do not too long ago.
[15:07:58] <ZATK> does the price change once I go from aluminium to steel
[15:09:10] <FinboySlick> ZATK: You can do it with the same mill, but your time cost is going to go up significantly if your mill wasn't designed with steel milling in mind.
[15:10:07] <gregncnc> Are you looking at router type machines?
[15:11:12] <FinboySlick> Yeah, steel on a router-type machine is just asking for sorrow.
[15:13:14] <ZATK> I'm doing small amounts of steel and a lot of aluminium
[15:13:25] <ZATK> thinking of doing
[15:13:39] <ZATK> not doing anything now
[15:13:44] <gregncnc> what are the dimensions and features?
[15:13:56] <FinboySlick> ZATK: Aluminium can be tricky to machine.
[15:14:12] <ZATK> 25cm box
[15:14:37] <gregncnc> A 250mm cube of aluminum takes a serious machine
[15:14:54] <ZATK> not cube
[15:15:00] <FinboySlick> ZATK: Like side panels to build a box?
[15:15:02] <gregncnc> sheetmetal
[15:15:17] <ZATK> more like 25cm 25cm 3cm
[15:15:30] <FinboySlick> That's still a hunk of metal.
[15:15:34] <ZATK> aluminium
[15:15:41] <gregncnc> OK 30mm still serious amchine
[15:16:11] <FinboySlick> You just drilling a few holes or are you machining a significant amount of that volume?
[15:16:12] <gonzo_> sounds like you are new to machining. CNC does not take the skill away, it just changed the woy you apply it. So suggest you get a nmanual mill and use that to learn on
[15:17:04] <ZATK> I was thinking of starting will a manual mill
[15:17:15] <gonzo_> then you will get the feel of what sort of machione you are going to need for a small production shop
[15:17:33] <ZATK> I was hoping I could just add steppers to one
[15:17:40] <FinboySlick> ZATK: Can you rent some time on a manual mill?
[15:17:45] <gregncnc> if you want to do that in one setup you need 12+" of y travel
[15:18:12] <ZATK> yea
[15:18:28] <gonzo_> many do just add steppers, possiblly also replacing the lead screws, as the hobbyist mills can have quite cheap ones
[15:18:48] <FinboySlick> ZATK: Then I suggest you buy yourself a block of aluminium and mill your part. You'll get a much better feel for what's involved here.
[15:19:27] <ZATK> how much do I need to spend for a cnc
[15:19:31] <ZATK> mill
[15:19:34] <gregncnc> a fullsize pridgeport is 12"
[15:19:48] <gregncnc> Bridgeport
[15:20:06] <FinboySlick> gregncnc: He'd need a router-type for that kind of size, which sort of puts a big damper on his ability to do steel.
[15:20:13] <ZATK> 12" is good enough for me
[15:20:37] <gonzo_> bridgeports are avail in up to 48" tables
[15:20:42] <ZATK> It sounds like I need two machines
[15:21:00] <gregncnc> At 30mm thick you want a 1/2 endmill, no $1000 router will do that?
[15:21:29] <gonzo_> but a BP is going to be a big and heavy machine, so the space may be an issue
[15:21:31] <ZATK> my steel work is only 7cm in the largest dimension
[15:21:51] <ZATK> not thick
[15:22:24] <FinboySlick> gregncnc: He's going to have to do lots of small passes regardless. He can't get a mill rigid enough to handle those forces on his budget.
[15:22:39] <ZATK> a lot of what I'm doing is flatting/level aluminium plates
[15:23:05] <gregncnc> you also want a face mill then
[15:24:15] <gregncnc> Do you have your own printer design you're trying to produce? have you quoted any parts at shops?
[15:25:00] <ZATK> well how much would it cost for the mills I need
[15:25:43] <FinboySlick> ZATK: How many of the 25x25cm part do you plan to produce in a day?
[15:26:14] <ZATK> 5 min
[15:26:44] <ZATK> I have some other parts That I would want to make on the same day
[15:27:26] <gregncnc> 5 x 6 side per unit?
[15:28:22] <ZATK> I want to make smooth flat aluminium sheets
[15:28:24] <FinboySlick> On your budget, I'd try to retrofit a manual bridgeport-type. Assuming you're only machining two sides, you'd be able to place both setups on the table.
[15:28:51] <ZATK> with some engraving
[15:31:00] <ZATK> well what should I be looking for on ebay or other sites
[15:33:12] <gonzo_> if you are able to go and collect a big mill, ebay may find you a bargain. A commercial dealer will probably be able top arrange delivery, but you pay
[15:33:57] <gonzo_> dont underestimate the effort required to move something that weighs the same as a small car

[17:55:42] <Jymmm> Loetmichel: =)
[17:55:46] <FAalbers> Loetmichel, I can't turn the spindle

[17:56:12] <Loetmichel> FAalbers: i meant the "scanning" going in an X shape
[17:56:18] <Loetmichel> not in a + shape
[17:56:21] <FAalbers> Loetmichel, Ir am I getting it wrong with those angles
[17:57:15] <FAalbers> Loetmichel, Can you do that in CamBam ? Maybe by turning the surface and crate the toolpaths ?
[17:57:29] <Loetmichel> no idea
[17:57:34] <Loetmichel> never used camban
[17:57:39] <Loetmichel> cambam
[17:57:40] <FAalbers> Then turn the toolpaths and surface back ?
[17:57:43] <Loetmichel> altho i own a copy ;)
[17:57:45] <Tom_itx> if you can't it's hardly worth using at all
[17:58:16] <JT-Shop> Roguish: like most things jack of many trades but master of none
[17:58:27] <FAalbers> I only saw Horizontal and Vertical ... maybe there are other settings
[17:58:33] <Roguish> I hear ya.
[17:58:45] <Loetmichel> JT-Shop: thats a good thing actually
[17:58:57] <FAalbers> Loetmichel, IS that technique to avoid going with the grain ?
[17:59:43] <Loetmichel> FAalbers: yes, and to avoid any "slow steps" when you have nearly horizontal and vertical edges in your relief
[17:59:49] <FAalbers> Loetmichel, I'll try that next time
[18:00:08] <Loetmichel> so that you are crossing any straight line at a steep angle
[18:00:10] <FAalbers> Loetmichel, Right
[18:00:44] <FAalbers> Loetmichel, Thanks , I'll try that next
[18:01:16] <Loetmichel> also: use a ball mill
[18:01:30] <Loetmichel> with the biggest diameter possible to not use detail
[18:02:04] <Loetmichel> and set the finishing runs to less than 1/10 widht of the tool to get a REALLY nice finish
[18:03:11] <Loetmichel> it starts to get coarse at about 1/4 the diameter of the tool when using a ball mill
[18:06:04] <FAalbers> Loetmichel, I think I was using 1/4 width , but I was using a ball 1/8
[18:07:34] <FinboySlick> Loetmichel: https://media.giphy.com/media/Tyy3npxzOQJa/giphy.gif <-- When you miss the morning coffee threshold?
[18:07:51] <Loetmichel> i just added some commonplaces so you have a baseline in case you didnt get the memo ;)

[18:10:41] <Loetmichel> atm i look more like catweasle... damn, i NEED a shave ;)
[18:11:28] <FinboySlick> Loetmichel: Well, there's a broad range of Rutgerhauerism. That just means you're closer to the 'Hobo with a shotgun' version.

[23:48:56] <robinsz> andypugh, so dude ...
[23:49:12] <robinsz> car related question ...
[23:49:36] <andypugh> Never owned one, know nowt. :-)
[23:49:51] <robinsz> thats what they all say ... only obey orders right?
[23:50:25] <robinsz> you know this latex goop they have with a compressor, instead of carrying a spare?
[23:50:32] <andypugh> Yes
[23:50:56] <robinsz> it should just be "clean it out, bit of warm water and patch as normal" right?
[23:50:56] <andypugh> Not ideal if you have a huge puncture
[23:51:03] <robinsz> it worked fine
[23:51:08] <robinsz> perfect in fact
[23:51:19] <robinsz> the Continental water based latex stuff
[23:51:29] <robinsz> and now ... no one will repair it.
[23:51:44] <andypugh> Yes, though I am not sure what the rules are with tyre repairs at the moment. I know that my bike tyres are not legally repairable. But the shop does it anyway after explainign that.
[23:52:01] <andypugh> It’s the mess. They hate the mess.
[23:52:14] -!- asdfasd1 [asdfasd1!~332332@2.123.213.70] has joined #linuxcnc
[23:52:16] <robinsz> but they are going to have the mess either way
[23:52:17] <andypugh> If you take the tyre off yourself and wash it, then they might.
[23:52:37] <JT-Shop> the very reason I fix my bike tires
[23:52:48] <robinsz> im surprised my ford main dealer said "unrepairable if it has the goop in it" when it is a fore OEM thing
[23:53:04] -!- asdfasd has quit [Ping timeout: 272 seconds]
[23:53:12] <robinsz> but anyway
[23:53:13] <JT-Shop> patch may not stick right
[23:53:42] <andypugh> They abrade away the inside surface of the tyre and ream out the hole.
[23:53:45] <JT-Shop> but andypugh you have a near a car
[23:53:59] <robinsz> *technically* it should be just as repairable as normal then
[23:55:18] * JT-Shop calls it a day goodnight guys
[23:55:35] <andypugh> Try somewhere like Universal Tyres.
[23:56:11] <robinsz> tried all the locals and the ford main dealer ... same answer, bastards
[23:56:27] <andypugh> Actually, if you are feeling like a bit of fun, ring Continental and alk them
[23:56:39] <robinsz> I already posted on their FB page
[23:56:42] <robinsz> ;)
[23:56:45] <robinsz> and Ford UK
[23:58:14] <robinsz> so, apart from that ... the CNC shat itself mid sheet
[23:58:24] <robinsz> servo amp died.
[23:58:54] <robinsz> fortunately ... the encoders are powered from the motion card
[23:59:01] -!- asdfasd1 has quit [Read error: Connection reset by peer]
[23:59:32] <robinsz> I de-powered the drives, got out the spare. fitted it, set it off again, didn;t even need to re-home :)
