[00:12:36] <XXCoder> hmm who did I chat with about glass drop thats very strong
[00:12:51] <SpeedEvil> Rupert?
[00:13:05] <XXCoder> yah
[00:30:53] <Jut> is anyone out there?
[00:31:09] <XXCoder> I'm not out there
[00:31:12] <XXCoder> I'm in my room
[00:31:12] <Jut> ... i want to believe
[00:31:28] <XXCoder> I belive in my room
[00:31:31] <Jut> <==>
[00:31:38] <Jut> that was a flying saucer
[00:31:58] <Jut> i'm feeling defeated
[00:32:13] <Jut> wrt to latency
[00:33:03] <Jut> > 200us spikes every so often. i tried to clear the smictrl bits, but it seems not possible
[01:00:21] <anomynous> youre out there because im in here
[01:00:25] <anomynous> why is that so complicated?
[01:00:29] <anomynous> its obvious, duh.
[01:03:24] <aventtini6> hello guys
[01:04:04] <anomynous> hello
[01:04:37] <aventtini6> how is the traj on the 2.7
[01:04:48] <aventtini6> commpared to 2.6
[01:07:00] <archivist> much improved
[01:07:01] <XXCoder> no, I'm here. you'e out there
[01:07:02] <XXCoder> heh
[01:07:32] <archivist> jut some motherboards are like that
[01:07:38] <aventtini6> i want to update some of my machines
[01:08:06] <anomynous> hey hey what is vector calculus
[01:08:33] <aventtini6> man i have change some thrust berings and i cant understand why they are so expensive
[01:08:46] <aventtini6> 500e per pcs
[01:09:13] <aventtini6> and a ballscrew is for the machine is 700E brand new
[01:09:15] <aventtini6> :)))
[01:09:27] <XXCoder> https://youtu.be/ubwPm9UK4F8
[01:11:06] <aventtini6> japannn
[01:11:07] <aventtini6> :D
[01:12:05] <anomynous> it took me a while to realize what it is supposed to do
[01:15:02] <XXCoder> fancy. http://makezine.com/2016/01/22/an-arduino-powered-laser-engraver-that-you-can-build/
[01:18:30] <anomynous> wee
[01:19:22] <anomynous> i maded a support for a dish machine plate support out of aluminium.
[01:19:25] <anomynous> :U high tech
[01:20:20] <anomynous> i hope dish wash doesnt corrode it
[01:20:58] <XXCoder> unless dishwasher contains couple possile elements, it wont.
[01:21:23] <XXCoder> up to point as I recall alum would evenually corrode in constant wet
[01:21:24] <anomynous> couple possible elements?
[01:21:32] <XXCoder> gallenium for one
[01:21:38] <anomynous> never heard of it
[01:21:38] <XXCoder> thats one metal killer
[01:22:14] <XXCoder> other one (forgot which) causes alum to be unable to coat with tough alum oxide coat so it willbreak alum down
[01:22:44] <anomynous> so if it starts doing to take it for anodizing?
[01:23:28] <archivist> anodising process uses sulphuric and caustic solutions
[01:24:25] <archivist> the thickness can be adjusted for various levels of protection from pretty to 30 years outdoors
[01:24:48] <anomynous> thats 10 years inside a dish washer
[01:24:49] <anomynous> ;D
[01:26:39] <XXCoder> geez https://youtu.be/YsLnBcXIH4E
[01:26:45] <XXCoder> dangerous.
[01:27:11] <Jut> i was just reading that Tormach is using linuxcnc now, instead of Mach3
[01:31:18] <anomynous> roughing jaws roughing jaws. Muah. No more sawing. Thin grip work holding. Low gripping area and tall workpieces. Muah.
[01:31:26] <Jut> I wonder if/what Tormach will give back to linuxcnc
[01:32:32] <archivist> Jut, an improved trajectory planner has been given back already
[01:43:48] <Jut> oh wow, that's really cool they gave back some improvements
[01:45:07] <Jut> archivist, i wonder what motherboard/cpu/chipsets Tormach is using in their linuxcnc computer
[01:45:53] <archivist> not sure
[01:52:44] <anomynous> https://www.youtube.com/watch?v=pAdSz4zZs74 look like phun
[01:57:24] <XXCoder> sparkies
[02:01:55] <Jut> https://youtu.be/412N5A-N8Fc?t=77
[02:05:40] <XXCoder> https://www.youtube.com/watch?v=c1K5QjR3hyU
[02:05:53] <XXCoder> one of my favorite "sparky" cutting
[02:16:00] <XXCoder> check this artcle. http://hackaday.com/2016/01/18/whats-in-a-tool-a-case-for-made-in-usa/
[02:30:38] <Deejay> moin
[02:32:29] <archivist> XXCoder, I happen to collect adjustables
[02:34:12] <archivist> sometimes the design is just plain wrong regardless of where made http://www.adjustable.archivist.info/
[02:35:37] <XXCoder> that is.. strange
[02:35:57] <XXCoder> my bro has dad's old weird wrench
[02:36:07] <XXCoder> handles so short
[02:37:29] <archivist> it is a tool that gets redesigned by hundreds, often with basic mistakes
[02:38:35] <archivist> that site is way behind, so many more to add
[02:42:18] <XXCoder> cool
[03:08:01] <Jymmm> Hi XXCoder
[03:08:09] <XXCoder> yo
[03:08:11] <yasnak> https://vid.me/X0M4
[03:08:20] <jym> Hi xx
[03:09:04] <XXCoder> "untrusted connection" on vid.me
[03:09:59] <yasnak> hmmmm, it wasn't interesting anyways. just bored finishing up a few jobs.
[03:10:25] <yasnak> https://vid.me/W3Oc must be a cert issue for geotrust
[03:10:47] <jym> Xx coder. book nick completion in this client
[03:10:58] <jym> no*
[03:11:57] <jym> xxcoder no nick completion on this client.
[03:12:17] <XXCoder> oh
[03:12:27] <jym> well, no TAB button
[03:12:58] <Jymmm> XXCoder: Theres is on THIS one though ;)
[03:14:10] <Jymmm> bu bye me
[03:34:51] <XXCoder> http://www.bridgecitytools.com/blog/2010/10/25/5-for-a-18-twist-drill-only-in-america/
[03:34:52] <XXCoder> geez
[04:14:05] <SpeedEvil> http://www.chinalawblog.com/ I find very enlightening
[04:14:53] <SpeedEvil> http://www.chinalawblog.com/2015/03/china-factory-problems-always-your-fault.html
[04:15:53] <SpeedEvil> http://www.chinalawblog.com/2013/08/how-to-get-good-product-from-china-specificity-is-the-key-to-your-oem-agreement.html also
[04:20:16] <XXCoder> interestng
[04:21:50] <SpeedEvil> If you don't actually say you want your 'good quality' drillbits to be of a certain hardness, and made from a certain quality of metal - with specific damages to be paid if they are not - then you may get nothing like what you expected when you specified a 'good quality' drill.
[04:26:24] <XXCoder> interesting
[04:26:40] <XXCoder> man I hate sites that have design of visited links as same color as unvisited.
[04:27:54] <SpeedEvil> A repeated theme is US companies requiring contracts drawn up with ajudication in the USA. Which chinese courts will never, ever enforce. Whereas a proper chinese contract, according to chinese law, written in chinese has a good chance.
[04:36:07] <XXCoder> interestng
[05:53:43] <XXCoder> SpeedEvil: man
[05:53:53] <XXCoder> been reading so many stuff on that page
[05:54:16] <XXCoder> its required reading for one thinking about forming a company or something that plan to use China as source
[05:54:30] <XXCoder> I didnt plan to, but good read reardless.
[06:05:19] <SpeedEvil> XXCoder: It's not so relevant if you're just ordering random stuff from china from aliexpress or ...
[06:05:29] <XXCoder> I know
[06:11:04] <trentster> XXCoder: ha ha check this out - just finished making this out of reclaimed oak - just noticed this! https://monosnap.com/file/i0VQTDEUcorBTfIqrPOGVC4WOQeERF
[06:11:26] <XXCoder> lol
[06:11:43] <XXCoder> cnc cut nail or was it healed over or something?
[06:11:43] <trentster> carbide bits must have gone over it like butter - I checked them no damage to any cutting edge
[06:12:14] <trentster> nah it was cut by both end mill and 1/8 ball nose seperately during the operations
[06:12:51] <XXCoder> leave it, it'll be great story lol
[06:12:55] <XXCoder> unless its for some client
[06:13:00] <trentster> yeah it adds character
[06:13:23] <trentster> nah I was playing with making 3d models and then engraving along the models surface
[06:13:24] <XXCoder> trentster: funny till I saw floor, I was thinking table size.
[06:13:36] <XXCoder> it must be a foot wide or something?
[06:14:02] <trentster> I work in metric its about 350mm diameter
[06:14:20] <XXCoder> so its around 14 inches
[06:14:23] <XXCoder> rough;ly
[06:14:35] <trentster> yup
[06:14:48] <XXCoder> I follow 300mm = foot approxation
[06:14:51] <XXCoder> works pretty well.
[06:15:09] <trentster> yeah - I always get confused with non metric stuff
[06:18:41] <trentster> heh I actually caught the nail being cut on video, I just checked
[06:20:54] <XXCoder> nice
[06:20:56] <XXCoder> sparky?
[06:21:08] <trentster> nah - just sound changed
[06:21:27] <XXCoder> interesting
[06:21:36] <trentster> I am uploading clip to youtube now - was filming with my phone so a bit dodgy
[06:21:56] <AmsterdamJoe> Hi. I want to design and visualize a bench with my computer, then, potentially using CNC to cut the wood build it. ofc, i use exclusivly foss so im wondering what 'tool-chains' or 'product-pathways' should i be examine?
[06:22:35] <trentster> AmsterdamJoe: a bench as in a work bench?
[06:22:39] <XXCoder> trentster: tell me time before it shows so I dont need to watch entire handheld video
[06:22:54] <trentster> ya
[06:22:58] <XXCoder> handheld videos are my kryrimite basically
[06:23:00] <AmsterdamJoe> its an *expirementall* desk
[06:23:42] <trentster> AmsterdamJoe: you got a big footprint cnc, and what you want to make it out of plywood?
[06:24:18] <AmsterdamJoe> i want to make it from red wood and use copper for finishing
[06:26:30] <AmsterdamJoe> can i use foss toolchain to make expirmental desk bench from copper and red wood?
[06:27:15] <archivist> a qualified maybe
[06:28:27] <archivist> a 3d cad freecad, there are others
[06:29:28] <archivist> what is the most important, visualisation or?
[06:29:55] <AmsterdamJoe> i can kind of imagine it, but visualization helps
[06:30:56] <archivist> having realistic expectations helps too
[06:31:12] <AmsterdamJoe> how so?
[06:31:48] <archivist> various packages/programs have different abilities
[06:32:04] <AmsterdamJoe> thats why i asked about product-pathways
[06:32:16] <archivist> dont expect one tool to do everything
[06:32:26] <AmsterdamJoe> Let's say i want to go from idea, to sketch, to visualization to CNC
[06:32:59] <archivist> visualization to CAM to CNC
[06:33:09] <AmsterdamJoe> 0_0
[06:33:35] <trentster> AmsterdamJoe: did you look at the video I linked?
[06:34:27] <archivist> not all cad deals with 3d(assemblies) as well as you may want
[06:34:41] <trentster> it basically covers everything you mentioned idea, to sketch, modeling, CAM and fabrication
[06:39:19] <AmsterdamJoe> i dont see a link
[06:42:30] <XXCoder> I saw something about using program to try fit as many parts into single sheet
[06:42:42] <XXCoder> so can get more parts by cnc
[06:43:30] <XXCoder> cant find it though
[07:37:02] <jthornton-> a nesting program
[09:00:08] <maxcnc> Hi
[09:00:28] <maxcnc> XXCoder: sheetcam can do this also
[09:01:07] <maxcnc> Ice here on side roads
[09:01:13] <maxcnc> but nothing like NY
[09:01:35] <maxcnc> some people may be hard effected today
[10:08:03] <CaptHindsight> SpeedEvil: it's article written to keep lawyers busy. You have already lost by following that advice.
[10:09:27] <CaptHindsight> the incentive has to be higher profits for the Chinese manufacturer based on QC, your QC not theirs
[10:15:57] <gregcnc> 7i77 has the X axis moving. The encoders on my ebay servos aren't 5,000 count, but 5000 lines! theoretical 0.125 micron resolution! Fortunately, I'll run out of voltage before 7i77 runs out of bandwidth for rapids 4m/min for this tiny lathe.
[10:17:10] <pcw_home> 5000 lines is pretty high ( about as high as non-interpolated encoders normally go )
[10:18:59] <gregcnc> old renco i couldn't find specs for, heidenhain didn't even have any info
[10:20:01] <gregcnc> can 0-10V/dir for spindle be set up in pncconf?
[10:22:58] <pcw_home> not sure if pnnconf can do that (its easy in hal as the absolute component has a direction bit output )
[10:24:28] <gregcnc> uh oh, being that old, this encoder might have low bandwidth, 300k? rapids would need 600kHz. Does it just lose count when the limit is reached?
[10:24:31] <gregcnc> I did see the hal method for absolute spindle
[10:51:25] <pcw_home> Yeah higher resolution encoders are often limited to 200-300 KHZ (so 800 --> 1200 Kcounts/sec)
[11:33:19] <archivist> the internet is a bit quiet on getting inside your own probe and cleaning the contacts
[11:39:56] <maxcnc> hi
[11:40:51] <maxcnc> pcw_home: a stupid question is there a issue on powering a system up First 7i76 then 5i25 time within betwheen
[11:41:29] <maxcnc> as i understad if 5i25 powerd up first 7i76 not found
[11:42:15] <maxcnc> gregcnc: http://linuxcnc.org/docs/html/examples/spindle.html
[11:43:33] <aventtini6> hello guys
[11:43:53] <aventtini6> any one knows a ajax premier lathe?
[11:43:58] <pcw_home> They can be powered up in any order but 7I76 field/5V power must be there when LinuxCNC is started
[11:44:13] <maxcnc> ok
[11:47:03] <maxcnc> aventtini6: the new 260 or the older ones
[11:47:28] <maxcnc> fagor 800 inside
[11:53:27] <aventtini6> fagor 800
[11:53:33] <aventtini6> battery went dead
[11:53:37] <aventtini6> https://www.youtube.com/watch?v=Ux5PWhELD0Q
[11:53:38] <PetefromTn_> jeez the cold sucks ;)
[11:53:47] <aventtini6> :))
[11:54:00] <aventtini6> it was the original battery
[11:54:04] <aventtini6> from 96
[11:54:08] <aventtini6> so it was good
[11:58:23] <maxcnc> did you lost all the parametics
[11:58:38] <aventtini6> i dont know
[11:58:46] <aventtini6> it has some parameters
[11:58:57] <aventtini6> but not know if there are the original
[11:59:16] <aventtini6> maybe default
[11:59:30] <maxcnc> i think fagor 800 got a dead ram security flag not like MAHo deckel
[11:59:58] <maxcnc> there you got in trouble with near 1000 parametics
[12:00:11] <maxcnc> took me about 2hr to man prog
[12:00:54] <PetefromTn_> warming up the shop, warming up the CNC, warming up the PetefromTn ;)
[12:01:16] <aventtini6> i can use dnc i think
[12:01:47] <aventtini6> the guys from ajax told me to send the plc to them and uplode them
[12:01:49] <maxcnc> PetefromTn_: weather is realy nasty in the US east
[12:02:50] <PetefromTn_> sure is....we just got like four or five inches of snow and it is just barely flurrying right now. But it is still a little cold here
[12:03:16] <maxcnc> aventtini6: the fagor got te standard scasii out you can go for linuxcnc
[12:03:47] <maxcnc> Pete we warm up here from the last cold days
[12:03:47] <aventtini6> yes its a simple retrofit
[12:04:15] <aventtini6> but i want to use the keybord
[12:04:39] <aventtini6> i just need some one whit similar machine
[12:04:46] <maxcnc> keyboard is trelated to 24V switches inside
[12:05:00] <maxcnc> i think there is also a relay board
[12:06:10] <zeeshan|2> aventtini6: do you have manual for grundig ste-02 ?
[12:07:02] <PetefromTn_> yup still sux tho...
[12:07:06] <Jymmm> even accommodates wheelchairs http://www.dailymail.co.uk/travel/travel_news/article-2842486/World-s-longest-rollercoaster-zip-line-twists-turns-mile-Australian-forest-thrill-seekers-suspended-60-FEET-ground.html
[12:07:32] <aventtini6> zee only the bosch drives
[12:07:49] <aventtini6> you dont need the grunding
[12:07:55] <Jymmm> PetefromTn_: Better get used to it ;)
[12:07:55] <aventtini6> its simple
[12:07:59] <maxcnc> zeeshan|2: do you got a FP5
[12:08:26] <aventtini6> look on my thred traub gloria and there are the bosch drive setup
[12:08:41] <aventtini6> also cncbasher know how to set it up
[12:09:00] <aventtini6> i will get my mesa next week and start on my large mikron
[12:09:23] <PetefromTn_> Jymmm Bullshit man not for long... and don't even jinx me like that we are still waiting to hear back on our last counter offer volley LOL
[12:09:49] <Jymmm> PetefromTn_: Did you get boxes at least?
[12:10:08] <PetefromTn_> no not yet but I got lotsa boxes in the attic
[12:10:28] <aventtini6> exe box?
[12:11:03] <maxcnc> is FedEx the main post box service in the USA acordiung to DHL
[12:11:47] <maxcnc> im off its weekend
[12:11:57] <Jymmm> PetefromTn_: This is you isn't it? http://fox17.com/news/local/photos-winter-storms-dump-snow-throughout-tennessee
[12:12:26] <PetefromTn_> yeah pretty much..
[12:12:30] <PetefromTn_> hang on for a pic.
[12:13:42] <aventtini6> BOBO are you on?
[12:13:53] <aventtini6> i have fix the maho mh500
[12:15:57] <Jymmm> PetefromTn_: Whats taking you so long? I know you dont have the photo packed up somewhere ;)
[12:16:57] <PetefromTn_> damn cellphone
[12:17:10] <Jymmm> PetefromTn_: Are you putting on your dino suit and taking a new pic?
[12:17:34] <PetefromTn_> dino suit?
[12:17:41] <Jymmm> Oh yeah, blame the phone, and the poor innocent toaster too.
[12:18:21] <Jymmm> PetefromTn_: Yes, dino. That was a video of a guy wearing a dino suit in TN shoveling snow.
[12:18:54] <PetefromTn_> http://i.imgur.com/UfH1b1Q.jpg
[12:19:04] <PetefromTn_> there ya impatient bastard ;)
[12:19:22] <PetefromTn_> http://i.imgur.com/qx0xGzg.jpg the driveway
[12:19:26] <Jymmm> PetefromTn_: WTH?! I dont want to see snow, I want to see YOU in a dino suit shoveling snow!!!
[12:19:40] <PetefromTn_> can't help ya man....not sure anyone can!
[12:20:06] <Jymmm> lol, did you not see the video?
[12:20:27] <PetefromTn_> no been busy keeping warm
[12:20:51] <PetefromTn_> got a big stick of 1/2 x6 inch steel plate I gotta turn into more exhaust manifolds here
[12:21:10] <Jymmm> PetefromTn_: This is you isn't it? http://fox17.com/news/local/photos-winter-storms-dump-snow-throughout-tennessee
[12:21:21] <Jymmm> PetefromTn_: scroll to the bottom for video
[12:22:01] <PetefromTn_> GOD am I sick of having to watch a freaking BS commercial any time I click a freaking video
[12:22:28] <Jymmm> Install an ad blocker. I haven't seen an ad in years.
[12:22:45] <PetefromTn_> that's disturbing
[12:23:02] <PetefromTn_> probably the only warm suit that idiot had to wear maybe
[12:23:46] <PetefromTn_> man I sure am a negative bastard this morning....maybe its the cold ;)
[12:24:50] <Jymmm> PetefromTn_: It's just PMS.... PetefromTnForeverandEver Mean Streak
[12:26:08] <PetefromTn_> heh probably with my luck...
[12:26:24] <Jymmm> PetefromTn_: Just sit near the fire with special coffee, you'll warm up
[12:26:38] <PetefromTn_> spoke to my friend in Florida yesterday he was complaining it was 60 degrees LOL
[12:27:01] <PetefromTn_> my kerosene heater is warming up the shop and I don't drink Coffee
[12:27:47] <Jymmm> Fine, toss a straw into a bottle of JD and suck it!
[12:28:20] <PetefromTn_> don't drink :D
[12:29:13] <Jymmm> Then be your friend so you too can bitch about 60F being too cold!
[12:29:50] <PetefromTn_> working on that.. hopefully with any luck we will be bitching about how hot it is in Florida in about two months ;)
[12:30:00] <Jymmm> lol
[12:49:16] <Duc> morning
[13:42:54] <Duc> PCW: have you ever run into someone having a issue with just one of the encoder ports on the 7i77 card? I switched my X from 0 to 03 encoder and I think the missing rawcounts was fixed.
[13:43:45] <pcw_home> No, never heard of a problem like that
[13:44:59] <Duc> odd for awhile there, the X-axis would drift without the raw counts changing but not its holding the position perfect when I switched it. Only moved the connector and changed the hal file to reflect the new spot.
[13:46:39] <Duc> now holding I mean
[13:47:32] <Duc> I will do a few more test to make sure it is fixed
[13:48:16] <pcw_home> are the settings the same for all encoders? (filter bit) because drifting in closed loop usually means noise
[13:49:39] <Duc> yea
[13:51:41] <Duc> all of them are set for 1
[14:13:56] <bobo__> aventtini6: your Maho is running again , that is good. what was the failure you fixed?
[14:14:54] <pcw_home> Duc: I would also check the 7I77 encoder jumpering and input levels ( if differential, measure across A and /A, B and /B in both states )
[14:20:52] <Duc_mobile> pcw_home: jumpers are the same, across A and /A is 2.7v but b and /B is low at 1v
[14:21:33] <pcw_home> thats suspicious
[14:21:35] <aventtini6> bobo
[14:21:50] <Duc_mobile> not really sure how to even adjust that coming out of the yaskawa drives
[14:21:50] <bobo__> yes
[14:22:15] <aventtini6> errors on the MAHO X01 X01 or Y01 Y01 Y01 i35
[14:22:28] <aventtini6> refer to liniar scales
[14:22:34] <pcw_home> make sure its not dithering when you measure (turn the servo drive off)
[14:23:04] <aventtini6> machine cant work if temp is mim 10
[14:23:27] <Duc_mobile> pcw_home: ok now it reads 2.7 on all of them
[14:23:27] <aventtini6> and scales must be clean with alchol
[14:24:04] <aventtini6> so machine is running perfect now
[14:24:18] <aventtini6> exept i have change all the capacitors
[14:24:45] <aventtini6> and i have found in a 85 machine minim of 6 capacitors dead
[14:24:57] <bobo__> aventtini6 yes X - Y - Z - B prefix 01 refer to each scale
[14:25:05] <aventtini6> yes
[14:25:06] <Duc_mobile> pcw_home: according to the yaskawa software the drive is now holding rotation and I verified with the old mechanical scales on the mill. Before the yaskawa software and the mechanical scales would change but not linuxcnc.
[14:25:28] <Duc_mobile> before I switched the encoder channel used
[14:26:14] <aventtini6> liniar scales must be perfect . Because of the flood vapors it make a thin lair on them
[14:26:41] <aventtini6> and they give some intermintent errors
[14:27:34] <bobo__> aventtini6 have you read the Deckel and the Maho section at pratical mach web site lately
[14:27:47] <Duc_mobile> pcw_home: For now I will just leave that encoder channel empty since I dont need 6 axis. At most I will have 5 anyways
[14:27:47] <aventtini6> no
[14:28:15] <aventtini6> liniar scale are philips
[14:28:30] <pcw_home> Its possible the one channel is bad but seems unlikely, My guess is that something else changed at teh same time
[14:29:04] <aventtini6> i need some parameters for a ajax premier lathe fagor 800
[14:29:15] <bobo__> interesting read on cleaning scales and replacing their seals
[14:29:19] <aventtini6> if some one know a guy
[14:29:31] <aventtini6> maho dont have any seals
[14:29:42] <aventtini6> this is made by flood vapors
[14:29:58] <Duc_mobile> pcw_home: Maybe but Im not to worried. Still leaps and bounds better than my stepper setup. Hate to mess with a new board now that its working LOL
[14:30:11] <pcw_home> (Channel 0 uses all the same signals as channel 1 so you would expect errors on channel 1 also unless ist was just a input chip problem but those tend to be all or nothing)
[14:30:18] <aventtini6> because i cant see the on a osciloscope
[14:30:39] <bobo__> Oh you have philips scales. i just saw
[14:31:00] <aventtini6> retested the machine with 4 diffrent tech guys
[14:31:04] <aventtini6> no luck
[14:31:14] <aventtini6> i found the hard way
[14:31:36] <Duc_mobile> pcw_home: when I used to do chip level repair on flight simulator boards, once in awhile we would see half a chip fail but its very rare
[14:33:04] <pcw_home> They are also 26LS32As which have a 25V max input voltage and are pretty hard to kill
[14:33:42] <bobo__> aventtini6 wish I could help , but I am a nuebe with the Maho stuff
[14:34:43] <bobo__> and wish I had a CNC lathe
[14:36:57] <aventtini6> i have tested and retroffited all off may machine
[14:37:24] <aventtini6> but i a little upset on linux not getting same feed rates
[14:38:06] <bobo__> aventtini6: did you get my message ,a few days ago about those Maho error codes ?
[14:38:15] <aventtini6> and also the spindle its a little low power
[14:38:39] <aventtini6> for example my mikron work perfect on 1 mm on a 16mm mill
[14:39:07] <aventtini6> and after linux im getting no more the 0.250mm
[14:39:14] <aventtini6> yes
[14:39:24] <bobo__> good
[14:39:32] <aventtini6> not that good
[14:39:58] <aventtini6> i sens that i cant developt torque on the original servos
[14:40:17] <aventtini6> or someting strange
[14:40:38] <bobo__> aventtini6 good you got the maho error code message
[14:40:58] <aventtini6> 10x for it
[14:41:02] <aventtini6> you the man
[14:41:30] <bobo__> I am just a wimp
[14:42:49] <aventtini6> dont worry time will solve all
[14:42:59] <aventtini6> you want to retorfit your maho
[14:43:00] <aventtini6> ?
[14:43:46] <bobo__> yes , but need to build a garage first
[14:43:55] <aventtini6> thats bad
[14:43:56] <aventtini6> :D
[14:44:23] <aventtini6> what liniar scales HH?
[14:44:47] <bobo__> yes HH scales
[14:45:36] <aventtini6> so its simple
[14:45:45] <aventtini6> TNC150?
[14:46:46] <bobo__> aventtini6: where could Maho information be posted ,so all can see and add to ?
[14:46:54] <aventtini6> and drive is indramat ?
[14:47:26] <aventtini6> i can help you if you have a electritian
[14:47:31] <bobo__> indramat drives yes
[14:47:33] <aventtini6> no problem
[14:47:47] <aventtini6> only i dont know how to make tool changer
[14:49:03] <aventtini6> did you get the mesa ?
[14:50:21] <bobo__> Tdm series of drives on the mh600e2 that has tool changer . the mh600e has the older SCR type indramat drives
[14:50:43] <aventtini6> yes they are simple
[14:52:07] <aventtini6> did you get exe box
[14:52:08] <aventtini6> ?
[14:52:17] <aventtini6> or use the HH board
[14:52:18] <aventtini6> ?
[14:52:29] <bobo__> I have not started any change to linux yet , as i need a garage first
[14:53:13] <bobo__> will try to use the HH board
[14:54:09] <anomynous> what is hh board?
[14:56:41] <aventtini6> The original liniar scale board thats in the original PLC
[14:56:49] <aventtini6> i allways use it
[14:57:01] <aventtini6> because i cant sell the old plc here
[14:57:22] <aventtini6> so i have a number of 8 HH plc in may storage
[14:57:24] <aventtini6> :))
[14:57:54] <bobo__> the control box has about 9 boards of which 1 is a HH scale converter Bd. , it only reads the scales and outputs to the control
[14:59:46] <aventtini6> if you send me pic we can solve it
[15:02:41] <bobo__> as far as i know all 3 machines were working. i saw 2 of them running before buying. and the 3rd mach --was told it was working
[15:03:12] <aventtini6> you have 3 off them?
[15:05:09] <bobo__> But as of now nove of the (2 mh600e = 1mh600e2 ) have elect power. wateing for a garage
[15:05:48] <aventtini6> why did you get mahos ?
[15:05:59] <aventtini6> you are making molds?
[15:13:19] <bobo__> avanttini they were cheap and was cheaper to get them than to not try to get parts if i only had one . 2 spare part machines . no i am just a burnt out old guy that can not stand TV or setting in a bar
[15:15:28] <aventtini6> im not really satised on the mikrons
[15:15:34] <aventtini6> and also maho
[15:15:52] <aventtini6> feed rate is low
[15:15:56] <aventtini6> precision is good
[15:16:10] <aventtini6> for me a a mold maker
[15:16:36] <aventtini6> i lost time with them
[15:16:49] <bobo__> I chose Maho instead of Deckel due to Maho not using needle bearings
[15:18:54] <aventtini6> i have KRYLE VMC 700 from 97 and i did see the true power on feeds 30000mm/m
[15:19:05] <aventtini6> precision is not perfect
[15:19:16] <aventtini6> but save times
[15:19:39] <bobo__> aventtini6 these machines are old old old compared to the newer stuff available now.
[15:20:14] <aventtini6> also i getting some fllowing errors because of the belts
[15:20:48] <bobo__> My newest (mh600e2) is a 1990 machine
[15:20:50] <aventtini6> but because of the liniar scales i get the best precision whit the cost of time
[15:20:58] <aventtini6> i have 4 mikrons
[15:21:07] <aventtini6> from 85 to 94
[15:21:24] <aventtini6> max feed 4000mm/m
[15:21:54] <aventtini6> now i have payed 500 euro for 1 trust bearings on the kryle
[15:22:30] <CaptHindsight> http://www.ebay.com/itm/MITSUI-SEIKI-VERTICAL-CNC-MACHINING-CENTER/401048842728 $4k or best
[15:22:36] <aventtini6> the maho and mikrons dont bracke easy
[15:22:43] <bobo__> mikrons Mr zeeshan is looking for a horz over am support for his Mikron
[15:22:54] <aventtini6> i know i dont have
[15:23:39] <aventtini6> seiki is good but not from us
[15:27:59] <aventtini6> bobo what motor you have on the Z axis
[15:28:09] <aventtini6> indramat MDC 9.20?
[15:30:15] <bobo__> don't remember , think MAC 071A ES
[15:32:48] <aventtini6> i need a MDC motor for a huron
[15:33:08] <bobo__> know the Y (has brake on motor) is larger
[15:34:18] <Erant> Well, that's interesting... I can push this 1/4" carbide rougher to 30IPM, 0.25" DOC, 0.04" WOC through 1018.
[15:34:54] <Erant> Which is more material removal than the 3/8" rougher I've been using for 6061. Obviously I'm doing something wrong there :)
[15:43:38] <SpeedEvil> CaptHindsight: If you have a contract which is a noop, then you are worse off than if you have a contract which can be enforced in local courts.
[15:52:02] <PetefromTn_> Well Folks it's official they accepted our offer on our house so barring the home inspection and appraisal giving us any issues we will be Florida Bound in a few short months!! I am about to pass out over here LOL...
[15:53:05] <SpeedEvil> Congrats.
[15:53:23] <PetefromTn_> thanks man... I was beginning to think it was never gonna happen LOL
[15:55:40] <PetefromTn_> Now we have a boatload of work to do getting everything finished and packing and moving etc. etc. etc. Uggghhh
[15:58:30] <FloppyDisk5_25> congrats! Good luck moving!
[15:59:13] <PetefromTn_> thanks flop we are excited about it. I have moved quite a few times in my life and it never gets easier but at least we are moving where we want to be now.
[16:11:59] <Jymmm> PetefromTn_: Months? YOu have yo get your ass out in days!
[16:13:03] <Jymmm> PetefromTn_: https://www.youtube.com/watch?feature=player_detailpage&v=Q8Tiz6INF7I#t=13
[16:16:25] <gregcnc> Erant, shorter tools have a positive effect on "machine stiffness"
[16:17:31] <Erant> gregcnc: Yeah, that obviously makes sense (less of a 'lever')
[16:18:10] <zeeshan|2> PetefromTn_: congrads man!!!!!!!!!!!!!!
[16:18:16] <Erant> But I can't help but think that I'm doing something wrong with the 6061 rougher. I used a different process to get at these feeds, so I should go back and do that with the 3/8"
[16:18:31] <Erant> This is also a carbide tool vs the other one being HSCobalt.
[16:22:37] <gregcnc> PetefromTN_ is closing set yet? I talked someone who accepted an offer a day after listing and moved out in 3 days to close the deal, but they were basically ready to go. I hate to think of moving even the small machines I have..... in the basement.
[16:26:25] <Deejay> gn8
[16:26:56] <PetefromTn_> Jymmm I know right get my ass movin'
[16:27:09] <PetefromTn_> zeeshan|2 Thanks man we are quite excited and nervous LOL
[16:27:32] <zeeshan|2> hehe itll be so nice down there
[16:27:35] <PetefromTn_> gregcnc as part of our counteroffer agreement we set the closing date to march21
[16:27:56] <PetefromTn_> zeeshan|2 hell yeah it will be man we really love it down there.
[16:28:16] <PetefromTn_> We went back there for vacation this past year and were hatin' having to drive back home LOL
[16:28:49] <PetefromTn_> I fished on the beach almost every day and we ate out at the seafood restaurants we loved when we lived there every night LOL It was Glorious!!
[16:28:57] <zeeshan|2> hehe
[16:29:03] <zeeshan|2> itll be the life man!
[16:29:10] <zeeshan|2> wear hawaii shirts
[16:29:57] <PetefromTn_> I lived in shorts and tees down there man. and some flops most of the time too.
[16:30:14] <PetefromTn_> hopefully I can hookup with another race shop or something nearby too
[16:40:57] <Jymmm> PetefromTn_: oh and congrats
[16:41:48] <Jymmm> PetefromTn_: Now, get your ass off irc and get those damn boxes out of the attic. Actually empty the ENTIRE attic in the next 24Hours
[16:46:10] <PetefromTn_> well I would but right now I have a BUNCH of steel plates to machine over the weekend.
[16:53:02] <PetefromTn_> I also have to machine a couple more RX7 rotors as well
[16:55:50] <Erant> PetefromTn_: We had a bitch of a time closing on our place, so we had to keep pushing the closing date out. I hope it doesn't happen to you, but it's possible.
[16:56:00] <Erant> Do they have a financing contingency?
[16:56:29] <PetefromTn_> apparently they are pre approved
[16:56:44] <Erant> Yeah, so were we. Until our bank backed out.
[16:57:09] <PetefromTn_> all I know is we have a signed sales agreement with the customer and it is sold until it isn't LOL
[16:57:36] <PetefromTn_> are you asking about our closing on a new house or the closing on our current house?
[16:57:44] <Erant> Current
[16:58:12] <Erant> It all worked out in the end, we just got our keys a month after we thought we would.
[16:59:08] <PetefromTn_> well supposedly the realtors we used do not show homes to people until they are pre approved by a bank or credit union or something so that should not be an issue. As I said the only thing that can sour it is if the home inspection pops up something we cannot agree to fix ( not likely) or if there is a problem with the appraisal..
[17:23:21] <JT-Shop> making progress Pete
[17:23:28] <PetefromTn_> just posted on that uship site. hopefully I get some reasonable rates....
[17:23:55] <PetefromTn_> JT-Shop what are you up to now LOL
[17:26:04] <JT-Shop> trying to organize my shop some and I'm getting a 1500 sq ft building put in for my equipment and stuff
[17:26:25] <JT-Shop> I meant you are making progress on your house
[17:26:35] <PetefromTn_> jeez that is a nice sized building man...
[17:26:56] <PetefromTn_> I will honestly be lucky to find a house that will be able to take these machines and have room like I have here.
[17:27:21] <JT-Shop> yea it will be wood frame metal skin, slightly insulated
[17:27:41] <JT-Shop> that will give me 3500 sq ft total
[17:27:53] <PetefromTn_> nice.. that is a big shop to me anyway
[17:28:57] <JT-Shop> the garage is a little over 1000 and is attached to the shop which is a tad under 1000 the equipment building will be about 30' away from the shop
[17:31:10] <PetefromTn_> nice
[17:31:24] <JT-Shop> and this kills me but it will not be lined up with the rest of the buildings and the sun and moon lol
[17:31:45] <PetefromTn_> wish me luck finding a decent house with a shop sized garage down in Port St. Lucie for a reasonable price LOL
[17:32:02] <JT-Shop> pick any two
[17:32:30] <PetefromTn_> yeah exactly right
[17:32:48] <PetefromTn_> I am hoping to find a foreclosure or something like that...
[17:33:35] <JT-Shop> hows the job market down there?
[17:34:05] <PetefromTn_> meh probably no better than here.
[17:38:48] <PetefromTn_> my wife has worked for the Hospital system down there when we used to live there and they have expressed interest in having her back
[17:39:05] <JT-Shop> that's a good thing
[17:39:54] <PetefromTn_> yeah and she has more certs now than she did then. I can work for myself as I have been and if I can find something locally that works with my schedule all the better...
[17:41:13] <rob_h> evning ppl
[17:41:15] <JT-Shop> sounds like your almost set
[17:41:22] <JT-Shop> hi rob_h
[17:41:40] <rob_h> hows it your side of world? all we see on news right now is your snow :0
[17:42:17] <JT-Shop> lol, got 1" of it and it will be gone tomorrow, my sister north of Atlanta got 1/4"
[17:42:26] <JT-Shop> what about you Pete?
[17:42:51] <JT-Shop> I found the top of my work table today!
[17:43:13] <rob_h> aah not too bad then
[17:43:41] <JT-Shop> bad in some areas to the south of me I think
[17:44:00] <Valduare> hi guys
[17:44:28] <rob_h> we just have rain here as normal
[17:45:06] <JT-Shop> well you must be use to it by now lol
[17:45:06] <rob_h> i'v just about got the HMC running now we got before christmas its running jobs now at least
[17:45:39] <JT-Shop> nice!
[17:45:50] <rob_h> only had to fix the normal 2nd machine problems relay which is lucky i guess , like leaking pipes. and sticky valves etc
[17:45:53] <PetefromTn_> we got several inches over here today and yesterday
[17:46:06] <Valduare> got a question for you guys, what are the differences between using an arduino vs raspberry pi to run a little cnc mill
[17:46:31] <humble_sea_bass> an arduino is a slow little chip
[17:46:40] <JT-Shop> both sound like machine kit not LinuxCNC
[17:46:43] <humble_sea_bass> its basically architecture
[17:47:02] <Valduare> was looking at the mantis 9 cnc machine
[17:49:20] <humble_sea_bass> how do you plan on driving it
[17:50:10] <Valduare> from what im seeing, there are arduino and ramp boards
[17:50:16] <Valduare> i dont know much about this stuff yet
[17:51:10] <humble_sea_bass> well I imagine that the arduino is just serving as the motor controller
[17:51:48] <humble_sea_bass> you're still gonna need a computer, which would mean LinuxCNC as your best cheap option
[17:52:19] <Valduare> from what I understand, there is arduino, ramps board, stepper controllers, steppers and then your in business
[17:54:33] <JT-Shop> Valduare: http://twilightrobotics.com/cnc/cncnot1
[17:54:55] <Valduare> hmm broken images
[17:54:55] <humble_sea_bass> ah no shit http://sourceforge.net/projects/easycnc/
[17:55:09] <humble_sea_bass> someone made an app that talks to that setup
[17:57:51] <humble_sea_bass> unless you own all the materials already, this approach seems suboptimal
[18:00:48] <_methods> i don't think the pictures are the important part of the story lol
[18:01:25] <XXCoder> I hate special effect where it goes blur out
[18:01:32] <XXCoder> then focus in
[18:01:39] <XXCoder> expecially when it dont seem to change place
[18:02:30] <Valduare> i’ve read that guys blog on how “not”
[18:02:51] <XXCoder> is it about video effects?
[18:04:38] <Valduare> was responding to JT-Shop :P
[18:10:55] <jfindley> .
[18:11:45] <XXCoder> lol ok
[18:12:04] <XXCoder> I'd be interested in special effects how to not do
[18:15:24] <archivist> do not skimp on the software!
[18:15:34] <archivist> use linuxcnc :)
[18:15:52] <XXCoder> yeah zero cost is expensive but worth it!
[18:15:58] <jfindley> Nice. I think I could print a suitable mount for my micro mill to hold a laser. Sticker making would be awesome!
[18:18:30] <JT-Shop> not broken for me
[18:19:07] <JT-Shop> I don't see any images in that blof
[18:19:09] <JT-Shop> g
[18:22:14] <jfindley> I can drive small steppers directly from the 7i76, right?
[18:23:17] <archivist> via drivers
[18:23:44] <norias> so...
[18:23:53] <norias> i got a bunch of small diesel engines
[18:24:08] <norias> and i'm trying to think of projects for them
[18:24:35] <jfindley> norias: Submarine?
[18:24:48] <norias> these are around 7hp
[18:24:48] <Jymmm> build a robotic horse and sell to the gubermint!
[18:24:52] <archivist> no air under water
[18:25:04] <norias> archivist: snorkel
[18:25:18] <jfindley> archivist: pressurized air tanks
[18:26:12] <_methods> generator
[18:26:32] <norias> maybe i'll make a tractor
[18:26:44] <norias> _methods: one is set up as a DC generator
[18:26:47] <norias> 150V, i think
[18:27:15] <_methods> project complete
[18:27:19] <_methods> lol
[18:27:20] <norias> hah
[18:27:39] <norias> well, i think i'm going to hook an inverter up to it to get 120V AC
[18:30:49] <norias> i guess i could buy a tractor that needs an engine
[18:31:36] <Jymmm> norias: build a robotic horse and sell to the gubermint!
[18:31:54] <norias> Jymmm: no! my employer would definitely be mad
[18:32:13] <Jymmm> norias: build a robotic horse and sell to someone else's gubermint!
[18:32:28] <norias> my employer would certainly be mad
[18:33:17] <Jymmm> norias: build a robotic horse and sell to your employers competition!
[18:33:29] <norias> lol
[18:34:50] <Valduare> so what is this “realtime” kernal stuff I see mentioned
[18:35:27] <archivist> the bit of code that is accurately timed to match hardware needs
[18:35:32] <JT-Shop> LinuxCNC uses a special real time kernel
[18:36:15] <archivist> mechanical systems requires good timing for success
[18:37:47] <Valduare> ok
[18:41:04] <archivist> some of the toy code on aaaaaaarguinos violate proper timing for steppers
[18:41:59] <malcom2073> Tbh, the timing actually is done right on the arg-uinos, it's the physics that are questionable :P
[18:42:49] <archivist> malcom2073, skunkworks did some analysis of the acceleration
[18:43:48] <malcom2073> Ah, thought you meant the timing as in consistancy, not acceleration. Yeah they assume infinite acceleration
[19:08:24] <Valduare> oh neato 3d printer made from dvd rom steppers :P
[19:10:46] <XXCoder> Valduare: theres cnc using 2 floppy drives
[19:11:13] <Valduare> that confuses me
[19:11:21] <XXCoder> using its own screw drive and rails as well as motors built in
[19:11:30] <Valduare> are you talking the little floppys or the big 5.25 bay ones
[19:11:33] <XXCoder> its very precise but very weak too.
[19:11:42] <XXCoder> actually cant remember which hm a sec
[19:12:02] <Valduare> cause the big old 5.25 ones are valuble now see htem going for 50 bucks on ebay heh
[19:12:15] <XXCoder> ah small ones
[19:12:16] <Valduare> hard to tear into 50 bucks making it e-waste lol
[19:12:36] <XXCoder> NASA shops in ebay
[19:12:42] <XXCoder> for example 7 inch drives
[19:13:22] <XXCoder> https://sites.google.com/site/0miker0/home
[19:13:35] <XXCoder> cdrom version
[19:18:00] <Valduare> heh
[19:18:12] <Valduare> I never thought nasa used e-waste to keep the project running
[19:18:27] <Valduare> you’d assume they could just have a factory make runs of any chip design they wanted :P
[19:18:32] <Valduare> http://www.geek.com/chips/nasa-needs-8086-chips-549867/
[19:22:53] <XXCoder> they are SERIOUSLY under-budgeted
[19:23:01] <XXCoder> thats why they use 7 inch floppies, they need em
[19:23:05] <XXCoder> and software on em
[19:23:23] <XXCoder> people keeps thinking nasa is over budget but really theya rent.
[19:23:25] <XXCoder> *arent
[19:33:42] <Valduare> thats making it sound like this raspberry pi zero sitting infront of me can handle most of the tasks over there they have :P
[19:36:27] <XXCoder> some of em I guess yeah
[19:36:41] <XXCoder> they do have more modern stuff but some of tasks is still done by tape machines
[19:36:57] <XXCoder> as well as more modern machines requiring 7" floppy disks
[19:37:11] <Valduare> do you mean 8” floppy
[19:37:19] <XXCoder> possibly
[19:38:13] <XXCoder> though I bet you we can now make special drive that just reads entire thing and emulates it after.
[19:38:27] <XXCoder> no need to actually wear down drive
[19:38:32] <Valduare> aye
[19:38:44] <Valduare> so these cdrom cnc machiens
[19:38:57] <Valduare> im seeing few guides but no info on bed capacity
[19:39:08] <XXCoder> I'm guessing very small
[19:39:13] <XXCoder> inches
[19:39:34] <XXCoder> weight limit quite small too I bet, and low shear resistance
[19:39:34] <Valduare> wonder if it’d be big enough to print up case for raspberry pi
[19:39:43] <XXCoder> it might be able to cut wood using dermel
[19:39:56] <XXCoder> doubtful
[19:40:17] <Valduare> since im new to this stuff, im considering making one :)
[19:40:24] <XXCoder> honestly
[19:40:28] <XXCoder> its better make your own
[19:40:30] <Valduare> use it to help build parts for a bigger better one etc
[19:40:47] <Valduare> all the electronics I can swap over to a new build
[19:40:49] <XXCoder> cd drive cn is very fine resolution but very weak
[19:40:54] <Valduare> really not much skin off my nose etc
[19:41:20] <XXCoder> my suggestion? just buy electrics kit and build cnc
[19:41:46] <XXCoder> use drawers or something or rods
[19:41:59] <XXCoder> if it reaches enough precision you can build better machine with it.

[19:43:52] <malcom2073> You get what you pay for, that's a shit hotend
[19:44:28] <XXCoder> bit of internet issues bah
[19:44:40] <XXCoder> ah finally loading
[19:44:42] <Valduare> what would be a better hotend I dont know what makes a good one or not
[19:45:16] <malcom2073> If you're ust doing ABS andPLA, the Jhead is fantastic: http://hotends.com/
[19:45:51] <malcom2073> The reason that amazon one is called jhead, is because *that* jhead is amazing, fake name recognition
[19:54:02] <Valduare> hmm
[19:54:16] <Valduare> its just a block of metal that holds in a heating element isnt it? :P
[19:54:44] <malcom2073> That's like saying a car engine is just a block of metal with some explody bits :P
[19:54:58] <Valduare> no :P
[19:55:13] <XXCoder> I'm sure there is many factors
[19:55:37] <malcom2073> There are quite a few factors, I for one refuse to give any money to the chinese jhead clones, purely because of their lack of caring for copyrights
[19:55:53] <malcom2073> And partially beause I know the guy who makes jheads, and know how much of a headache it's been for him :P
[19:56:21] <Valduare> ah :P well there’s more of the story
[19:57:00] <malcom2073> That's the disclaimer, so throw away the knowlege if you wish for that
[19:57:56] <malcom2073> Eh it's a glue gun, I'm sure cheap chinese parts will be fiiine :P
[19:58:07] <Valduare> lol
[20:22:58] <Tom_itx> JT-Shop, got it all wired up yet?
[20:56:42] <unholycrab> cutting a 2" slot, with a 0.5mm bit. 2 flute, 1cm long shank
[20:57:03] <unholycrab> doing 0.25mm depth passes... 15"/min feed rate, 10k RPM (slowest)
[20:57:10] <unholycrab> the bits break immediately upon contact with the wood
[20:57:34] <unholycrab> what am i doing wrong?
[20:57:45] <malcom2073> Too high of chip load maybe? What do the feeds and speeds say?
[20:57:50] <unholycrab> what is chip load?
[20:58:00] <unholycrab> feed speed is 15"/min, malcom2073
[20:58:06] <unholycrab> i can slow it down to 3"/min and it still breaks
[20:58:11] <malcom2073> unholycrab: No. the calculations that tell you how fast to go
[20:58:17] <unholycrab> i have no calcuations
[20:58:31] <unholycrab> using vectric aspire to generate toolpaths
[21:00:28] <malcom2073> That's 0.2mm per flute, that is likelly too much for that tool
[21:00:31] <malcom2073> go much slower?
[21:00:50] <unholycrab> you mean the feed speed?
[21:00:54] <malcom2073> yes
[21:01:06] <jdh> using a 20 thou end mill?
[21:01:07] <unholycrab> its going to be a 12 hour cut
[21:01:18] <unholycrab> 34 slots
[21:01:19] <malcom2073> Yes
[21:01:21] <jfindley> chip load, important concept: http://www.pdsspindles.com/engineering-speeds
[21:01:31] <malcom2073> You're cutting a 2" slot with a tiny cutter, of course it's gonna be slow :P
[21:01:41] <malcom2073> Or crank up the rpm
[21:01:46] <malcom2073> 30krpm you can go much faster
[21:02:04] <malcom2073> Gotta remember, such a small tool isn't moving that fast at 10krpm in comparison to a larger tool
[21:02:05] <Tom_itx> too much vibration or spindle runout? .5mm isn't very big
[21:03:20] <jfindley> What drives should I use with 6i25 - 7i76 and 5V/1A NEMA 23s?
[21:03:39] <Tom_itx> gecko 302
[21:03:42] <malcom2073> jfindley: Gecko!
[21:03:47] <Tom_itx> pump them up to 40v
[21:06:15] <jfindley> Tom_itx: I don't see a 302 available on their site. I
[21:06:47] <malcom2073> Tom_itx: You thinking 203?
[21:06:55] <Tom_itx> ahh yeah 203
[21:07:03] <malcom2073> iirc, the 250 is the lower power version
[21:07:04] <Tom_itx> that's what i have
[21:07:20] <Tom_itx> 203v
[21:07:22] <malcom2073> The G540 that I have has 4 250's in it
[21:08:46] <unholycrab> ive got people telling me to slow the RPM down, people telling me to speed up...
[21:08:56] <unholycrab> my range is 10k to 21k
[21:09:13] <unholycrab> im going to try 21k rpm, 3"/minute, 0.25mm depth
[21:09:13] <Tom_itx> unholycrab, it's all about chip load and ipt (inches per tooth)
[21:09:19] <unholycrab> absolute absurd settings
[21:09:26] <jdh> that's a tiny endmill
[21:09:26] <Tom_itx> do some calculations first
[21:09:33] <malcom2073> Yeah, it's solid math, not guesswork
[21:09:40] <malcom2073> There should be really zero guesswork
[21:10:02] <Tom_itx> www.onsrud.com/plusdocs/Doc/index.html?model.code=FeedSpeeds
[21:10:15] <Tom_itx> http://zero-divide.net/index.php?page=fswizard&shell_id=199&load_tool_id=27011
[21:10:21] <Tom_itx> those two should help you
[21:10:43] <unholycrab> nice re: second link Tom_itx
[21:10:57] <os1r1s> unholycrab gwizard helps too
[21:10:58] <unholycrab> no wood in here though
[21:11:09] <unholycrab> and first doesnt' have a bit that comes close to the size i have
[21:11:32] <jfindley> Dang, those are pricey. Would one of the G251s work?
[21:11:48] <malcom2073> jfindley: I've had good luck with leadshines and the like, which are much cheaper
[21:12:27] <unholycrab> Tom_itx: the formula my friend gave me was RPM * diameter * 0.0005 or something
[21:12:31] <unholycrab> which makes no sense
[21:12:57] <malcom2073> If you need anti-resonance, you need a gecko or like a leadshine DM422. If you're alright without, you can get by *much* cheaper by getting one of the 6600 drivers
[21:13:32] <Tom_itx> unholycrab, .0005 would probably be the chipload
[21:13:47] <Tom_itx> so rpm * chipload * teeth
[21:13:51] <malcom2073> unholycrab: Also be sure you'[re not mixung units, you gave mm and inches
[21:14:08] <Tom_itx> or something like that...
[21:14:37] <unholycrab> im not. in inches, the bit diameter is 0.02"
[21:14:39] <Tom_itx> maybe it's rpm / (chipload * teeth)
[21:15:40] <unholycrab> heres my bit: http://www.ebay.com/itm/331555293245?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
[21:15:59] <jfindley> malcom2073: My machine is tiny and will be used for milling soft things. Can you recommend some brands I should look at, I'm pretty inexperienced in this area.
[21:16:04] <malcom2073> Alright just checking, you said it was 0.5mm earlier which is why I mentioned it
[21:16:11] <unholycrab> yeah definitely
[21:16:11] <os1r1s> Is there any reason I can't tune servos in linuxcnc before I attach them to the mill?
[21:16:15] <jfindley> *aside from leadshine and gecko
[21:16:34] <malcom2073> jfindley: Do you want to go as cheap, or nice?
[21:16:50] <unholycrab> for fun, im going to try 0.01" pass depth, 3"/minte feed rate, 21k rpm...
[21:16:51] <os1r1s> jfindley What size/kind of machine?
[21:16:56] <unholycrab> theres no way i can dial it down any farther
[21:17:00] <malcom2073> I've used these and they work well on a small tabletop router: http://www.omc-stepperonline.com/bipolar-stepper-motor-driver-max-4a-current-40vdc-input-16-subdivision-st6600-p-246.html
[21:17:30] <jdh> that looks like a tiny bit for cutting wood
[21:18:05] <unholycrab> jdh: people do it. im slotting a fretboard
[21:18:12] <jfindley> malcom2073: Mix of cheap and nice would be ideal. The machine is 205x115x58mm, 3 NEMA 23 5V/1A steppers, and a 9V/1A spindle that uses collets and small shanks.
[21:18:15] <unholycrab> i started with carbide bits, broke the instantly
[21:18:17] <unholycrab> HSS right now
[21:18:41] <jfindley> $150 would be a good max on how much I want to spend on the drivers, but I could go higher if it really made a difference
[21:18:48] <jdh> how deep do you want to cut?
[21:19:45] <jfindley> os1r1s: It's the one you sold me =)
[21:19:49] <malcom2073> jfindley: The big difference I've found between the 6600's and the G540, is that I can run much faster jog speeds with the gecko drive due to the anti-resonance. The Leadshine's have anti-resonance as well, but I've not investigated how well it does as much as I have with the 6600 vs gecko
[21:19:52] <os1r1s> jfindley I just figured that out :)
[21:20:15] <jfindley> os1r1s: Yeah, I don't like the TinyG, so I'm upgrading that stuff.
[21:20:18] <malcom2073> os1r1s: I've heard tuning depends on what the servo is attached too: More mass == different tuning
[21:20:37] <os1r1s> malcom2073 I was hoping I could get close before strapping them to the machine
[21:21:04] <malcom2073> I gave up on servos before I got them attached to my machine, so I'm just parroting what I was told when I was trying to tune them offboard :)
[21:21:09] <os1r1s> jfindley I use G540s on several other mills. It works really well
[21:21:33] <jfindley> os1r1s: Would I still need the 7i76 with the G540, since it's controlled via parport?
[21:21:42] <os1r1s> jfindley You don't need a 7i76
[21:22:08] <jfindley> Ok, I can probably sell that then.
[21:22:09] <os1r1s> jfindley A 6i25 or 5i25 will connect directly to the g540
[21:22:32] <jfindley> I already bought a plug n go kit with a 6i25 and 7i76
[21:22:35] <os1r1s> jfindley Or, you can just use a parport to the G540. I use 6i25s, but parport works
[21:22:49] <os1r1s> The 6i25 + the g540 work well together
[21:23:16] <jfindley> should have talked to you before I did that, I suppose =)
[21:23:33] <os1r1s> You can use the 6i76 of course. But its a lot more wiring
[21:24:28] <os1r1s> jfindley You only need three G250s
[21:24:41] <os1r1s> So you could just get that and plug it into the 7i76
[21:32:07] <unholycrab> ok so 3"/minute works, and then when i increase to 6"/minute, it breaks
[21:32:13] <unholycrab> looks like im camping overnight looking at this CNC machine
[21:32:31] <unholycrab> something like 25 passes per 2" slot, of which there are 34
[21:33:20] <jdh> something with less stickout might be more rigid
[21:34:00] <os1r1s> unholycrab What is the slot width?
[21:34:09] <unholycrab> 0.02" os1r1s
[21:34:36] <os1r1s> So you are cutting 25 slots .02" wide?
[21:34:55] <unholycrab> 34 slots
[21:35:00] <unholycrab> 2" wide
[21:35:11] <unholycrab> slot width is 0.02"
[21:35:22] <gregcnc> have you checked tool runout?
[21:35:25] <unholycrab> think of a guitar neck. the neck is something like 2" wide
[21:35:54] <os1r1s> unholycrab I'm trying to understand why you would use such a small bit
[21:36:10] <unholycrab> os1r1s: because the fretwire is 0.023" wide, and needs to be hammered into the slot
[21:36:27] <gregcnc> this operation is normally done with slitting saws
[21:36:42] <unholycrab> gregcnc: ive seen people do it with end mills on youtube at much faster feed rates
[21:36:53] <unholycrab> my reason for using the end mill, is that i want to do non-linear frets at some point. ie: for just intonation
[21:36:58] <unholycrab> the fretwire will be bent
[21:37:02] <unholycrab> and the slots will be curved
[21:37:32] <gregcnc> is that tool and endmill, how many flute?
[21:37:34] <os1r1s> unholycrab Its not a continuous cut then
[21:37:46] <os1r1s> unholycrab Just where the raised parts are to hold the fret wire, right?
[21:37:58] <os1r1s> unholycrab Like this? https://www.jescar.com/wp/wp-content/uploads/2014/01/fretwire1.jpg
[21:38:43] <unholycrab> os1r1s: http://www.ebay.com/itm/331555293245?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
[21:39:02] <os1r1s> unholycrab ? That is the ebay link again
[21:39:10] <unholycrab> thats the end mill im using os1r1s
[21:39:32] <os1r1s> unholycrab I got it, but that doesn't answer my question. It appears its not a continuous cut
[21:39:38] <os1r1s> Per the picture I linked to
[21:40:05] <unholycrab> im not sure what you mean. its one cut per fret
[21:40:16] <os1r1s> unholycrab https://www.jescar.com/wp/wp-content/uploads/2014/01/fretwire1.jpg
[21:40:29] <os1r1s> Is that what you are slitting? The pieces that hold the wire?
[21:40:31] <unholycrab> this is what the fretwire looks like http://www.lmii.com/products/mostly-not-wood/fretting/fretwire/nickel/silver-fretwire
[21:40:46] <unholycrab> see how its a mushroom shape? it has a shank that goes into the wood
[21:40:59] <unholycrab> you cut a slot in the wood, just the right diameter
[21:41:02] <os1r1s> unholycrab I get that. Can you look at the image I linked to?
[21:41:04] <unholycrab> and you hammer the fretwire shank in
[21:41:17] <unholycrab> it looks like a guitar neck, with frets on it
[21:41:21] <unholycrab> not sure what you mean by "raised parts"
[21:41:30] <unholycrab> the "raised parts" are probalby the metal fretwire im talking about
[21:41:55] <unholycrab> the fretwire has a mushroom shape. the stem of the mushroom goes into a slot in the wood
[21:42:12] <os1r1s> Got it. I think I understand now.
[21:42:19] <unholycrab> sorry, lol
[21:42:47] <os1r1s> Can you not go deeper and slower?
[21:43:13] <unholycrab> os1r1s: im trying combinations. so far my only success is 0.01" deep, 3"/minute
[21:43:17] <unholycrab> 11 hours to cut the neck
[21:43:21] <gregcnc> What is your psindle?
[21:43:26] <unholycrab> 21k rpm
[21:43:31] <unholycrab> i can go from 10k to 21k
[21:43:32] <gregcnc> what is it?
[21:43:42] <unholycrab> i dont understand the question
[21:44:08] <gregcnc> who makes the spindle?
[21:44:14] <gregcnc> model?
[21:44:27] <unholycrab> the spindle being the router? its a router bolted onto a shop bot
[21:44:37] <unholycrab> so no RPM controls, etc
[21:44:40] <unholycrab> just the switch on the router
[21:44:51] <gregcnc> 1/8" collet or are you using a collet adapter?
[21:45:02] <jdh> check runout on collet/etc?
[21:45:21] <gregcnc> runout is what I'm getting at
[21:45:43] <unholycrab> probably the ladder
[21:45:44] <unholycrab> let me get a pic
[21:47:08] <unholycrab> gregcnc: http://i.imgur.com/mC5gtPS.jpg
[21:47:27] <unholycrab> thats exactly how im using it. its as far in as it goes
[21:48:35] <gregcnc> I'd take that collet apart and clean it to start with. if you have an indicator check the runout installed in the spindle. Runout is the enemy with small endmills.
[21:49:32] <unholycrab> what does that mean
[21:49:51] <gregcnc> if the tool wobbles too much it simple can't work properly
[21:49:58] <unholycrab> ah, yeah i see
[21:50:01] <unholycrab> it goes in pretty smooth
[21:50:06] <unholycrab> fits very snug
[21:50:49] <gregcnc> doesn't necessarily mean it's coaxial to the spindle
[21:51:11] <gregcnc> how many flutes do the endmills have?
[21:51:31] <unholycrab> i think 2
[21:51:41] <unholycrab> its really hard to see
[21:52:57] <gregcnc> total cut depth is .230"?
[21:55:32] <gregcnc> https://www.youtube.com/watch?v=aQXrxskKa0M
[21:55:46] <gregcnc> this is what the operation should look like
[21:56:15] <unholycrab> yep
[21:56:25] <unholycrab> looks pretty fst doesnt it?
[21:56:27] <unholycrab> and deep
[21:56:35] <unholycrab> not a 11 hour cut
[21:57:11] <jdh> a few thou runout in spindle + collet + endmill would kill it.
[21:57:55] <unholycrab> maybe ill buy a new collet
[21:57:59] <unholycrab> im working out of a hackerspace...
[21:58:33] <jdh> find an indicator and check the endmill shank
[21:59:16] <gregcnc> check the number of flutes. one or two flutes is OK.
[22:01:08] <unholycrab> if i had a microscope i could figure it out
[22:01:21] <unholycrab> looks like 2 flutes to me
[22:07:52] <unholycrab> 0.02" pass depth seems to be okay
[22:09:08] <unholycrab> nope. it broke
[22:09:46] <os1r1s> unholycrab Is it in hardwood?
[22:10:48] <unholycrab> ebony, os1r1s
[22:10:52] <unholycrab> pretty dense wood
[22:11:00] <unholycrab> but it probably chips really nicely
[22:11:27] <os1r1s> unholycrab So the deflection at .02 depth is .11
[22:11:35] <os1r1s> Which is pretty significant
[22:11:48] <unholycrab> i dont know what that means os1r1s
[22:11:57] <os1r1s> Its how much the bit is bending
[22:12:02] <unholycrab> ah
[22:12:22] <unholycrab> so im not convinced it wont break eventually at 0.01" depth, either
[22:12:43] <os1r1s> Deflection with that is .059"
[22:13:10] <unholycrab> whats a good deflection?
[22:13:15] <yasnak> none
[22:13:16] <yasnak> haha
[22:13:19] <unholycrab> and how are you computing this
[22:13:26] <yasnak> unless hsming
[22:13:29] <unholycrab> someone is cutting into ebony with an end mill somewhere
[22:13:46] <unholycrab> with carbide end mills
[22:14:23] <yasnak> Are you using that EM/Router on wood?
[22:14:30] <unholycrab> yasnak: its ebony
[22:14:32] <os1r1s> unholycrab gwizard has a nice calculator
[22:14:41] <yasnak> Make sure you get some air gun or something to blast at the cut, those flutes will pack up fast and blow the endmill
[22:14:59] <unholycrab> they look pretty clear, yas
[22:15:08] <yasnak> So whats the issue?
[22:15:14] <yasnak> Sorry, cleared my logs
[22:15:58] <unholycrab> yasnak: im cutting guitar fretboard slots. 0.02" diameter bit. 0.01" depth passes
[22:16:07] <unholycrab> 21k rpm (fastest), and 3"/minute
[22:16:10] <unholycrab> this is an 11 hour cut...
[22:16:15] <unholycrab> and the end mills break
[22:16:24] <unholycrab> im going VERY slow, and VERY shallow
[22:16:26] <yasnak> How deep?
[22:17:02] <yasnak> And how does the cut start? From the side or from a pre-drilled hole?
[22:17:35] <unholycrab> it plunges, then moves sideways
[22:17:43] <unholycrab> its a profile cut, via vectic aspire
[22:17:47] <yasnak> So you plunge that?
[22:17:48] <unholycrab> not actually a profile though
[22:18:00] <yasnak> Into the material or do you walk it in from the side?
[22:18:04] <unholycrab> it plunges 0.01", then cuts accross. then plunges down another 0.01", and cuts accross
[22:18:10] <unholycrab> not walked in from the side
[22:18:19] <yasnak> I wouldn't do that...do y ou have a drill?
[22:18:32] <unholycrab> i do have a drill
[22:18:41] <yasnak> http://www.pmtnow.com/
[22:18:44] <yasnak> Is that the EM?
[22:18:44] <unholycrab> i can also make the CNC do it
[22:18:59] <unholycrab> no. its this yasnak http://www.ebay.com/itm/331555293245?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
[22:19:38] <yasnak> 2ft?
[22:19:40] <yasnak> 2 flute?
[22:19:46] <unholycrab> these look very epensive. i've broken 6 bits already trying to find settings
[22:19:53] <unholycrab> actually 12 counting yesterday
[22:19:58] <unholycrab> yasnak: yeah 2 flute
[22:20:03] <yasnak> Eh, those ones are cheap for me. I run metal tho
[22:20:16] <yasnak> i would honestly pre-drill as many holes within the slot as you can
[22:20:22] <XXCoder> tiny usually means need lots rpm
[22:20:36] <yasnak> Then plunge the mill into the first pre-drilled hole and do your first pass.
[22:20:37] <XXCoder> those definitely are tiny
[22:20:43] <unholycrab> ive heard oppositing opinions. lots of RPM, lower RPM...
[22:20:45] <yasnak> Depends. If its burning or cutting
[22:20:53] <XXCoder> yeah
[22:21:00] <XXCoder> need to calcute
[22:21:03] <yasnak> Wood isn't my area
[22:21:11] <XXCoder> fast rpm, fast feed rate
[22:21:21] <unholycrab> XXCoder: i have no clue how to calculate. ive heard lots of different formulas. the GWiz thing looks insane
[22:21:22] <XXCoder> that is whatwood tend to need from what i understand
[22:21:28] <yasnak> But I know how to machine and when you see that mill you have to remember that you're putting alot of force on just the first 0.01 of that long flute
[22:21:44] <yasnak> How deep are these slots crab? Can you get a shorter flute? Then it wouldn't deflect as much
[22:22:19] <XXCoder> might help. https://www.carbidedepot.com/formulas-turning.htm
[22:22:45] <unholycrab> yasnak: 0.08" deep, XXCoder
[22:22:47] <unholycrab> yasnak:
[22:23:11] <yasnak> How long is the flute?
[22:23:54] <yasnak> But seriously, drill out as much as you can before. Plus alot of these small mills aren't center cutting so thats alot of heat generated just rubbing it away before each cut.
[22:24:17] <XXCoder> interestin. if I use 20 IPM and 27000 RPM, it will cut 0.001 chips
[22:24:19] <unholycrab> i meansured the flute just now at 0.25"
[22:24:34] <yasnak> thats way too long
[22:24:39] <unholycrab> yeah they are long
[22:24:42] <yasnak> you need something like a 3mm flute
[22:24:45] <yasnak> 0.118"
[22:24:50] <unholycrab> well, at the rate that im breaking these
[22:24:58] <unholycrab> it will cost me hudreds of dollars to figure out how to cut this neck
[22:24:58] <yasnak> 0.5mm?
[22:25:09] <unholycrab> 0.5mm diameter, or 0.02" diameter
[22:25:19] <XXCoder> whats groove size youre cutting?
[22:25:26] <XXCoder> might be able to use larger tool
[22:25:31] <unholycrab> they are around 2" across
[22:25:40] <yasnak> okay, so why not use a keyway slotting tool to rough the 0.02" slots out
[22:25:43] <unholycrab> the groove size needs to be 0.02" or 0.023" max
[22:25:47] <XXCoder> youre making 2" grooves using that tiny use?
[22:25:49] <XXCoder> oh!
[22:25:51] <yasnak> and put the stock on its side
[22:26:23] <unholycrab> yasnak: interesting. what is this thing
[22:26:24] <yasnak> http://www.harveytool.com/prod/Browse-Our-Products/Specialty-Profiles/Keyseat-Cutters_198/Keyseat-Cutters---Square_83.aspx
[22:26:36] <yasnak> those are for metal, i can find you cheaper if you think it'll work
[22:26:48] <yasnak> carbide actually is worthless for wood, you'd be better off with HSS
[22:27:05] <unholycrab> are you serious
[22:27:24] <yasnak> I mean don't quote me but it makes no sense. Unless the stuff is somewhat abrasive
[22:27:44] <XXCoder> unholycrab: indeed. carbide dont work for wood and plastics
[22:27:54] <unholycrab> looks like one of these slotter is $24
[22:27:55] <XXCoder> plastics depends but not wood
[22:27:57] <unholycrab> $42*
[22:27:58] <unholycrab> thats absurd
[22:28:03] <yasnak> yeah but dude
[22:28:06] <yasnak> these are for metal working
[22:28:09] <XXCoder> get HSS unholycrab
[22:28:14] <yasnak> and must preform on swiss machines. you don't need these
[22:28:19] <unholycrab> are you guys still talking english
[22:28:22] <yasnak> i just wanted to show you this and see if it would work
[22:28:30] <unholycrab> i see
[22:28:45] <XXCoder> unholycrab: HSS is "High speed steel" which is great on soft metal like alum, plastics and wood
[22:28:56] <XXCoder> stays sharp quite a while
[22:29:01] <yasnak> I mean, you can pick up jewlers saws for like 1$ at any width on ebay :P
[22:29:33] <yasnak> http://www.mscdirect.com/browse/tn/Milling/Milling-Cutters/T-Slot-Cutters?navid=12106241
[22:29:53] <yasnak> 0.02" might be hard to find, may need to go the saw way.
[22:30:16] <unholycrab> my goal is to do non-linear frets, ie: bent/curved slots
[22:30:20] <XXCoder> http://www.amazon.com/s?rh=n%3A256305011%2Cp_n_feature_seven_browse-bin%3A5485491011
[22:30:26] <XXCoder> example
[22:30:40] <unholycrab> XXCoder: the only ones ive found that are 0.5mm are the ones i linked
[22:31:23] <XXCoder> hmmn
[22:32:48] <yasnak> http://www.pmtnow.com/end-mill/TR
[22:33:40] <yasnak> shorter shank
[22:33:56] <unholycrab> $38 dude
[22:34:12] <yasnak> $13.65
[22:34:18] <yasnak> TR-2-0200-S .0200 .060 1/8 1.50 $13.65
[22:34:30] <unholycrab> oh you're right
[22:34:33] <yasnak> yeah
[22:35:20] <yasnak> i'd look at kyocera carbide too. msc sells them. cheap carbide drills/ems for circuit boards.
[22:41:58] <Sync> just be aware that your tooling will be more expensive than your machine
[22:43:44] <Sync> XXCoder: I had good success with carbide mills and wood, we run those micro toothed ones and they work very well
[22:43:53] <yasnak> maybe try a router bit
[22:44:11] <yasnak> but pre-drill as many holes as possible. then slot it
[22:44:13] <XXCoder> Sync: dont carbide usually get dull pretty fast on wood
[22:44:24] <yasnak> Nah, same edge.
[22:44:47] <Sync> why would it XXCoder?
[22:44:49] <yasnak> I doubt they make HSS 0.5MM, not something someone usually would need. 0.5MM is usually metal.
[22:45:05] <XXCoder> hm ok
[22:45:19] <Sync> HSS usually has a higher sharpness due to lower grain size
[22:45:37] <Sync> but for wood the toothed bits work well as they break the grain
[22:45:50] <Sync> they don't leave a perfect finish, but most wooden parts need to be finished anyway
[22:50:42] <yasnak> problem with wood and carbon fiber is the fibers
[22:50:46] <yasnak> they don't cut like metal
[22:50:59] <yasnak> you need a router type with either an upcut or downcut depending on what you're doing
[22:51:12] <XXCoder> Sync: can always do toothed to do rough cut
[22:51:19] <XXCoder> then use HSS to finish]
[22:54:29] <Sync> XXCoder: in wood that is unproductive
[22:59:10] <XXCoder> geez https://youtu.be/gcIwrdeP21s
[23:13:19] <yasnak> so i do have a question
[23:13:38] <SpeedEvil> XXCoder: why are you trying to do this.
[23:13:39] <yasnak> How does everyone keep their programs controlled and ordered?
[23:13:51] <XXCoder> SpeedEvil: trying to do what
[23:13:59] <SpeedEvil> XXCoder: There may be a better way to do it rather than the 0.5mm slot
[23:14:03] <SpeedEvil> err
[23:14:08] <SpeedEvil> unholycrab:
[23:14:16] <XXCoder> you on speed, speed? ;)
[23:14:22] <XXCoder> kidding
[23:14:24] <SpeedEvil> I am mostly asleep
[23:14:28] <yasnak> well the way i see it is...if you can't afford the tooling then do your searching on google for the product you're trying to make :P
[23:14:37] <XXCoder> ah too muchdowners then lol
[23:14:54] <SpeedEvil> LASERs!
[23:15:11] <XXCoder> that may be very well the best way
[23:15:18] <XXCoder> leaving burnt mark but nice for thin cuts
[23:15:44] <XXCoder> and lasts MUCH longer than any mere moral tools
[23:16:11] <SpeedEvil> Or you invert the problem.
[23:16:22] <SpeedEvil> And do it as two knife-cuts
[23:16:34] <SpeedEvil> chisel it out
[23:17:28] <yasnak> yeah, i mean why make it so complex on a cnc? i just figured if he was it had to be very exact
[23:17:39] <yasnak> or however exact those home cncs are
[23:19:11] <SpeedEvil> guitar fretboard slots - a tiny little dremel sawblade might actually be better
[23:20:12] <Sync> ah nice, got two forkardt chucks for 130€
[23:21:01] <yasnak> yeah not a bad idea, make a quick fixture to control depth
[23:23:38] <MattyMatt> cnc pencil, then junior hacksaw
[23:25:00] <unholycrab> SpeedEvil: what do you mean
[23:25:17] <unholycrab> i have access to a laser cutter
[23:25:48] <SpeedEvil> http://www.ebay.co.uk/itm/6x-HSS-Circular-Saw-Disc-Blades-3-17mm-Rod-For-Dremel-Metal-Rotary-Cutter-Tools-/331365811739?hash=item4d26f1061b:g:aWkAAOSwBP9UV056
[23:25:57] <SpeedEvil> LASER may be quite adequate
[23:26:10] <unholycrab> my goal is to do some pretty complex fretboards
[23:26:11] <SpeedEvil> the depth may be poorly controlled.
[23:26:15] <MattyMatt> if you crimp a spine on a hacksaw blade, you'll make a saw that only cuts the right depth
[23:26:15] <unholycrab> fret slots that are curved
[23:26:21] <SpeedEvil> ah
[23:26:23] <unholycrab> and a fretboard profile that is radiused, and scalloped between frets
[23:26:36] <unholycrab> everything is great and works perfectly except the end mills for the fret slots are breaking
[23:26:50] <SpeedEvil> If LASER will produce an acceptable cut, then that's almost certainly the easiest cheap way to go
[23:26:54] <unholycrab> as soon as i can figure this out, i have superior microtonal shitnut guitars
[23:27:05] <Sync> are you trying to cut with 100% stepover?
[23:27:25] <unholycrab> 0.01" pass depth, 0.02" diameter mill, Sync
[23:27:30] <unholycrab> 3"/minute feed rate...
[23:27:39] <SpeedEvil> unholycrab: how rigid is your machine
[23:27:45] <unholycrab> don't know what you mean SpeedEvil
[23:27:47] <SpeedEvil> can it actually repeatably do these cuts?
[23:27:48] <Sync> well, that's fine but what is your stepover
[23:27:55] <unholycrab> its a carbide end mill, 0.25" 2 flute kerf
[23:27:57] <MattyMatt> you could plunge and then join up the holes with the hacksaw
[23:28:06] <unholycrab> i dont know what a stepover is Sync
[23:28:23] <Sync> the amount of the cutter engaged in the cut
[23:28:59] <unholycrab> if its not hte pass depth, ie the depth of the bit going into the wood each pass, then i dont know what you mean
[23:29:08] <Sync> the width of your cut
[23:29:27] <unholycrab> the slots are 2.3" wide, roughly
[23:29:34] <unholycrab> 0.02" slot width
[23:29:43] <unholycrab> so the end mill is doing a straight line
[23:29:46] <Sync> okay
[23:29:53] <Sync> that is what breaks your mills
[23:30:00] <unholycrab> i don't follow
[23:30:27] <unholycrab> its a line, 2.3" long, 0.02" wide. the end mill is 0.02" wide
[23:30:33] <Sync> yes
[23:30:36] <MattyMatt> how deep?
[23:30:40] <unholycrab> so i should get a small end mill?
[23:30:41] <Sync> your tool engagement is 100%
[23:30:49] <unholycrab> MattyMatt: 0.08" deep, 0.01" deep each pass
[23:30:56] <unholycrab> ok, i see Sync
[23:31:04] <unholycrab> i can go as wide as 0.023", Sync
[23:31:20] <Sync> so you either need to make sure that you evacuate chips *really* well
[23:31:26] <MattyMatt> plunging is easier on the tiny endmills. use them like drills
[23:31:27] <Sync> or use a smaller endmill
[23:31:39] <unholycrab> cool
[23:31:46] <unholycrab> yeah i want to insert plunges at the ends of the lines, MattyMatt
[23:31:51] <unholycrab> multiple people have suggested that
[23:31:55] <Sync> and rough using paths that limit stepover
[23:32:03] <Sync> like trochidal milling
[23:32:03] <unholycrab> i was hoping vectric aspire had an option to do that automatically
[23:32:17] <unholycrab> trochoidal million you say
[23:32:31] <Sync> and you possibly want air forcing the dust out
[23:33:14] <unholycrab> doing that
[23:33:24] <Sync> or take smaller depths, but probably the limiting factor is your spindle speed
[23:33:26] <MattyMatt> and the slower you go, the less tools you break
[23:33:44] <Sync> because 3"/min is super slow
[23:33:47] <Sync> not really MattyMatt
[23:33:56] <Sync> you need to keep the tools within their working range
[23:34:03] <Sync> otherwise they won't work properly
[23:34:06] <yasnak> lol
[23:34:15] <yasnak> the slower they go the more they rub
[23:34:23] <MattyMatt> ah with carbide in wood, you can grind through
[23:34:30] <yasnak> seriously, i'm not being an asshole, but with common sense you can learn alot :P
[23:34:47] <yasnak> you can't "grind" you rub :P
[23:36:08] <Sync> if you don't cut you rub, that creates heat and ultimately burns your tools
[23:36:12] <Sync> so that's a bad idea
[23:36:22] <MattyMatt> wood burns before carbide
[23:36:34] <MattyMatt> the worst is it scorches like in a laser
[23:36:40] <Jymmm> Ya dont keep the cutter stationary, mkay
[23:37:14] <Sync> well, that will still break your tools
[23:38:15] <MattyMatt> I did a lot of oak with 0.03" cheapo carbides, and 90% of my breakages were clumsiness
[23:38:36] <MattyMatt> poor gcode, careless jogging etc
[23:39:27] <MattyMatt> but once you're in the wood, nothing stops carbide except going sideways too fast, IME
[23:40:41] <yasnak> or you know, overload
[23:41:12] <yasnak> 22k tho, what type of spindle did that guy have lol
[23:41:19] <MattyMatt> my machine is floppy
[23:41:39] <MattyMatt> 22k is roughly what my dremel does
[23:41:53] <yasnak> yeha but think of the runout in a crappy dremel bearing
[23:42:08] <yasnak> hes probably only cutting with one flute, its all over the place. 22k alone is enough to throw it all over
[23:42:50] <MattyMatt> it's the collet that causes all the runout on mine. the bearings are 608s and fine
[23:43:25] <MattyMatt> I need several attampts to get it sitting straight usually
[23:45:03] <yasnak> I'd buy an NSK spindle if I made a homemade CNC
[23:45:40] <yasnak> Amazingly loud though
[23:45:54] <MattyMatt> I got some ER16 chucks on 8mm straight shanks
[23:46:40] <MattyMatt> in a pair of 608, that should be better than the dremel
[23:47:52] <MattyMatt> but then I got a 500W palm router with its own 1/8" collet, so I haven't got around to the ER16 one
[23:49:00] <Sync> yeah those nakashini spindles are really nice yasnak
[23:52:18] <yasnak> yeah i have a few in some machines
[23:52:54] <yasnak> the new citizens have it integrated into the control which is real nice. no more addtional ladder crap and custom postconfigs.
