[00:03:17] <zeeshan> quiet in here :P
[00:07:47] <XXCoder> BOO
[00:09:01] <zeeshan> :P
[00:09:55] <zeeshan> https://www.youtube.com/watch?v=70rd9fK-UGg
[00:10:03] <zeeshan> anyway to make the motion a bit smoother?
[00:10:11] <zeeshan> what is g64 set to normally?
[00:10:15] <zeeshan> in 2.7
[00:15:12] <XXCoder> looking
[00:15:28] <XXCoder> there is 2 path planning modes
[00:15:38] <XXCoder> forgot G numbers
[00:15:45] <XXCoder> point to point and smoothing
[00:15:59] <zeeshan> it definitely looks like point to point is turned on
[00:16:08] <zeeshan> you really notice it during the rapids
[00:16:20] <XXCoder> point to point is great for sharp corners
[00:16:44] <XXCoder> there is also linuxcnc setting on how "flexiable" you want it to be
[00:16:49] <XXCoder> like .001 or whatever
[00:17:51] <XXCoder> gloves tsk
[00:19:21] <zeeshan> :)
[00:21:59] <XXCoder> g61 and 64
[00:22:12] <XXCoder> g64 is constant velcocity
[00:22:21] <XXCoder> g61 is exact stop mode
[00:22:40] <XXCoder> 61 is good for sharp corners while 64 is great for curves
[00:23:02] <XXCoder> though I do recall some setting in linuxcnc for g64
[00:23:36] <zeeshan> hm
[00:24:21] <XXCoder> oh
[00:24:23] <XXCoder> G64 P0.015 (set path following to be within 0.015 of the actual path)
[00:24:32] <XXCoder> apparently I was wrong
[00:24:42] * zeeshan reads
[00:24:45] <zeeshan> n goes to bed
[00:24:46] <zeeshan> thanks :D
[00:24:55] <XXCoder> np enjoy bed
[00:29:20] <yasnak> man
[00:29:34] <yasnak> i'm so lazy today
[00:35:58] <robin_sz> why did my cat have to go and wake me up?
[00:37:45] <evil_ren> cats dont need reasons
[00:56:59] <Crom> cats are the reason
[00:58:28] <Crom> OK my Jacobs 6A chuck from around 1934ish finally has an arbor! mt2-jt2 tanged
[00:58:35] <XXCoder> cats is reason cats exists.
[00:59:10] <Crom> nice 1/2" chuck holds down to tiny bits
[00:59:29] <Crom> My 33C only goes does to 3/64's
[00:59:41] <Crom> s/does/down/
[01:01:14] <Crom> 6a holds a #72
[01:01:24] <Crom> 0.025"
[01:06:50] <mow> I feel lazy every day
[02:00:15] <yasnak> Yeah had same issue here, ended up just turning the threaded end of a tiny mini chuck that wasn't for my kent and stuck it in a collet. Otherwise I never run anything less than 1/8 shank as we have hsc
[02:22:21] <Deejay> moin
[05:21:19] <Spida> http://www.rtmlk.com/2016/02/09/conflagration/ <- cnc machine lab of my university :-(
[05:21:30] <Spida> (not my pictures)
[05:22:24] <archivist> does not work on my browser
[05:23:51] <__rob> how much better is a carbide chucking reamer likely to be vs HSS ?
[05:23:58] <__rob> the price is like £20 vs £120
[05:24:13] <XXCoder> Spida: interesting. in my region it is illegal to go to place on fire
[05:24:33] <__rob> for alumninium*
[05:26:30] <XXCoder> Spida: basically, anti-gawker law
[05:26:45] <archivist> __rob, is this a hobby?
[05:27:38] <__rob> well, sort of
[05:29:48] <__rob> its not for someone
[05:30:24] <archivist> go into cromwell tools and get an hss one for cash
[05:33:31] <archivist> their online prices are silly
[05:35:04] <archivist> here is another supplier http://www.mscdirect.co.uk/cgi/insrhm
[05:35:48] <archivist> that last one is where I last got a reamer from
[05:36:03] <archivist> when it was still called J&L
[06:02:32] <__rob> great, thanks
[06:02:42] <__rob> the HSS ones will be good enough i'm sure
[06:03:23] <__rob> think i'll spot, drill, spot, drill for each layer, then ream the lot, without moving x,y
[06:03:29] <__rob> should be perfect
[06:20:20] <SpeedEvil> Spida: yeah - never good when you can see a fire in the distance in the skyline and there's stuff you care about below
[07:15:16] <yasnak> _rob: honestly, how many times will you need the reamer is the first question to ask.
[07:22:20] <__rob> yea, well its £20 from mscdirect, cheaper than a boring head
[07:23:40] <__rob> not so encouraging that their website spells energy efficient as "Emergy Effcient"
[07:24:14] <__rob> but prob not that often but still nice to have
[07:44:09] <archivist> probably printed on an Epsom printer :)
[07:45:18] <archivist> hehe 36 listings with the incorrect spelling on ebay
[07:45:57] <archivist> one idiot is putting epson epsom
[07:46:38] <malcom2073> That's not an idiot, he's catching people who misspell
[07:46:46] <malcom2073> He's selling to idiots :P
[07:47:39] <Jymmm> malcom2073: Did you just click BUY NOW by chance? ;)
[07:48:11] <malcom2073> Hah, I don't buy printers that use unobtanium to print :P
[07:48:20] <Jymmm> hahaha
[07:48:59] <archivist> malcom2073, he is an idiot because the ebay search engine fixes the search anyway
[07:49:12] <malcom2073> Eh? That's new, it didn't used to
[07:49:18] <malcom2073> At least as of a couple years ago when I used to sell stuff heh
[07:49:24] <archivist> had to use "" to find the miss spellings
[07:49:33] <Jymmm> It's kinda sad... I buy BRAND NEW $50-$60 laser printers and when the "trial" toner goes empty, I just buy another printer instead of a $79 toner cartridge.
[07:50:54] <malcom2073> Heh. I bought a used bigger office laser printer and have been using that
[07:51:09] <malcom2073> the toners are like $80 each, but so far I've only run out once this year, and only of one color. My wife prints a LOT of stuff
[07:51:23] <malcom2073> erm, once in the *past* year
[07:51:44] <Jymmm> malcom2073: what does she do with the printouts?
[07:53:12] <malcom2073> Jymmm: kid stuff, school stull, all sorts of stuff
[07:53:14] <malcom2073> apparently
[07:53:19] <malcom2073> (I just asked her that haha)
[07:53:21] <Jymmm> ah
[07:53:36] <Jymmm> lol
[07:54:32] <Jymmm> I worked at one company (as IT) and the accounting dept would print THREE of everything, emails, invoices, etc... 1) file copy, 2) office copy, and 3) archive copy.
[07:55:02] <Jymmm> they would go thru 4 CASES of paper each day
[07:55:06] <malcom2073> Ew
[07:55:20] <Jymmm> Had 6 printers setup and there was a waiting line
[07:55:38] <Jymmm> there were only 8-12 ppl in the dept.
[07:56:07] <Jymmm> tables were STACKED with printouts every day
[07:56:18] <Sync> wtf
[07:56:23] <malcom2073> That's awesome
[07:56:56] <Jymmm> Until you have 6 ladies calling you that they can't print all at the same time
[07:57:01] <Sync> none of which is really needed
[07:57:55] <archivist> I had printers off the back of serial terminals printing out delivery/invoice/whatever
[07:57:59] <Jymmm> It was a japanese based company, totally different culture.
[07:58:24] <SpeedEvil> Jymmm: how long did they store the archive paper?
[07:58:52] <Jymmm> SpeedEvil: NFC, I just knew they had an offsite storage somewhere.
[08:00:34] <Jymmm> SpeedEvil: My responsability ended when it left the printer =)
[08:02:54] <yasnak> anyone use backblaze or backup?
[08:03:02] <yasnak> *for
[08:03:19] <Jymmm> But we had an obscene budget to play with and bought lots of toys =)
[08:05:22] <malcom2073> Gotta love that
[10:20:03] <tiwake> roycroft: https://eugene.craigslist.org/pts/5434889250.html
[10:22:42] <zeeshan> hi
[10:23:37] <pink_vampire> hi
[10:23:58] <tiwake> zeeshan: got a mustang :P
[10:24:01] <tiwake> yesterday
[10:24:04] <zeeshan> did anyone get a chance to see my machining video and possibly tell me how to fix the jerkiness?
[10:24:05] <zeeshan> https://www.youtube.com/watch?v=70rd9fK-UGg
[10:24:06] <pink_vampire> 26
[10:24:08] <zeeshan> tiwake nice
[10:24:16] <zeeshan> which year
[10:24:37] <tiwake> 1998
[10:24:42] <zeeshan> nice :P
[10:24:44] <tiwake> its just a base v6
[10:24:44] <zeeshan> 5.0L?
[10:24:46] <zeeshan> AW:{
[10:24:48] <tiwake> 150hp
[10:24:51] <tiwake> buuuuut
[10:25:01] <tiwake> my friend has a motor he is going to give me
[10:25:10] <tiwake> to beef it up into a GT
[10:25:31] <zeeshan> :)
[10:25:49] <t12> that is a sweet machine zeeshan
[10:26:02] <zeeshan> t12 thanks :D
[10:26:10] <zeeshan> i really want to fix that jerkiness
[10:26:22] <zeeshan> i know its something to do with the trajectory planner settings
[10:27:17] <Erant> zeeshan: What are you powering the mister off?
[10:27:28] <zeeshan> air
[10:27:28] <t12> which jerkyness
[10:27:36] <t12> the varying speed when doing the series of cuts on the left
[10:27:38] <zeeshan> lemme show video at the portion
[10:27:42] <zeeshan> where i think it could be better
[10:28:02] <zeeshan> look at 3:55
[10:28:04] <zeeshan> when the tool returns back
[10:28:11] <zeeshan> it slows down around the corners
[10:28:13] <Erant> zeeshan: I got the air part. I meant more, what kind of compressor.
[10:28:33] <zeeshan> erant its a 18 scfm compressor
[10:28:36] <zeeshan> but you dont need that
[10:28:42] <zeeshan> you can do it off a pancake style
[10:28:46] <zeeshan> it doesnt use much air
[10:29:02] <zeeshan> to give you an idea , my tank is a 60 gallon, if its fully charged at 120psi
[10:29:13] <t12> still dont really see it
[10:29:16] <t12> unless you mean the rapids?
[10:29:18] <Erant> k, which one do you have? China special, or a koolmist or whatever?
[10:29:20] <zeeshan> and i turn off the pump, i can run the mister for 50 mins
[10:29:29] <zeeshan> noga minicool that has been modified
[10:29:29] <Erant> t12: There's a slow-down when it goes around the corner
[10:29:33] <zeeshan> t12 yes in the rapids
[10:29:46] <Erant> Because it's two combined axes
[10:29:54] <t12> what would you prefer the trajectory to be
[10:30:02] <Erant> And I think it might go speed-X + speed-Y = speed
[10:30:02] <zeeshan> maintain feedrate
[10:30:04] <zeeshan> around those corners
[10:30:05] <t12> that just looks like rapid accel limiting?
[10:30:13] <t12> the slow feedrate?
[10:30:40] <zeeshan> i mean i am happy with it
[10:30:44] <zeeshan> but if i can improve it
[10:30:46] <zeeshan> it'd be nicer
[10:30:52] <zeeshan> i plan to run only hsm paths in the future
[10:30:58] <t12> i guess i'm asking what the improvement goal is
[10:31:09] <zeeshan> t12 itd be faster
[10:31:11] <zeeshan> and less jerky
[10:31:13] <Erant> t12: Do you notice how it slows down as it prepares to enter the turn?
[10:31:23] <t12> is this hsm paths
[10:31:26] <zeeshan> yes
[10:31:37] <Erant> Right around like 3:43
[10:31:44] <t12> i think thats all adjustable in leadin parameters?
[10:31:53] <zeeshan> no
[10:32:06] <zeeshan> it could be actually
[10:32:14] <zeeshan> but i didnt see anything obvious inthe g-code, wasnt looking there
[10:32:29] <zeeshan> cause its happening during changes of direction only
[10:32:39] <Tom_itx> zeeshan fix your pid loop
[10:32:59] <Erant> zeeshan: Is this G0 or G1?
[10:33:05] <zeeshan> erant g1
[10:33:09] <Tom_itx> g1
[10:33:20] <zeeshan> mastercam for some reason likes to do backfeeds are g1
[10:33:28] <zeeshan> maybe cause it doesnt want to overshoot into a wall?
[10:33:38] <zeeshan> http://i.imgur.com/akA0vq9.png
[10:33:41] <zeeshan> this is what the tool path looks like
[10:33:43] <zeeshan> for a similar part
[10:33:44] <Erant> And the feed is set once?
[10:33:59] <zeeshan> no
[10:34:08] <zeeshan> cutting feedrate is set to 43ipm
[10:34:12] <PetefromTn_> zeeshan was that done in Mastrcam?
[10:34:12] <Erant> Or is doing a G2/3 around the corner with a different feed?
[10:34:14] <pink_vampire> what is that part?
[10:34:50] <zeeshan> and when it does the back feedrate, it lifts the tool up by 0.010" and back feeds at what rate you specify, usually for me this is 200 ipm
[10:34:54] <zeeshan> pete yes
[10:35:00] <zeeshan> Erant: lemme check
[10:35:31] <PetefromTn_> that is typical in my experience and it does it on HAAS machines or whatever. I think it is something in the parameters of Mastercam I am sure there is a way to fix it but I had the same thing
[10:35:47] <t12> i think with hsm
[10:35:49] <t12> buried somewhere
[10:35:54] <t12> is a python script that actually writes the gcode
[10:35:56] <t12> for a given machine
[10:37:45] <t12> from there i think you can work out exactly how it interpertes
[10:38:21] <t12> the .cps files I think?
[10:38:38] <t12> maybe its not python
[10:38:49] <zeeshan> N40 X-.8288 Y-.8641 F43. , then it does like many lines of xy moves, then it reaches the backfeed and does N6400 G3 X1.9834 Y1.608 I-.0689 J.0487 F200. and then it does a bunch of xy moves lines until the next cutting move
[10:39:03] <zeeshan> so its not changing feedrate at corners
[10:39:09] <t12> is this all adaptive clearing?
[10:39:13] <zeeshan> ya
[10:39:19] <t12> linuxcnc?
[10:39:22] <zeeshan> ya
[10:39:32] <zeeshan> how dare you ask me if im running anything but linuxcnc
[10:39:36] <zeeshan> :)
[10:39:38] <t12> is it bogging the gcode interperter
[10:39:48] <Erant> zeeshan: Huh. If it's F200, then that sounds like a LinuxCNC problem for sure.
[10:39:50] <t12> hsm adaptice clearing on too high of a resolution
[10:39:58] <t12> will spam ALOT of tiny moves in curves
[10:40:08] <t12> i've seen it get weird from bottlenecks in mach3 at least
[10:40:21] <Erant> That wouldn't be the case here, it's not actually machining
[10:40:35] <t12> sorry for my bad spelling
[10:40:45] <Erant> Just rapid-ing. And especially the G3 should be fine.
[10:40:45] <archivist> version of linuxcnc?
[10:40:50] <zeeshan> 2.7.3
[10:41:57] <t12> http://www.hsmworks.com/docs/hsmworks/2013/en/#StrategyAdaptive3D passes section
[10:42:04] <PetefromTn_> sometimes if you do NOT select keep tool down it will avoid some of that... but there are a lot of options you can play with in Mastercam to help fix it.
[10:42:18] <zeeshan> like what
[10:42:21] <zeeshan> i dont see any options
[10:42:40] <t12> somehow i missed that this is mastercam sorry
[10:42:54] <PetefromTn_> I have no idea what you are looking at I am just speaking in general about mastercam...
[10:43:00] <zeeshan> its doing it around corners
[10:43:02] <zeeshan> in between moves
[10:43:06] <zeeshan> without changing z height
[10:43:07] <Tom_itx> zeeshan does this movement show up in the gcode file?
[10:43:11] <PetefromTn_> I did not get tons of time to play with it
[10:43:33] <Tom_itx> start there and work your way to the pid loop
[10:43:43] <zeeshan> its not there in the g-code
[10:43:46] <zeeshan> but i did find one mistake i made
[10:43:54] <zeeshan> which can be part of the reason, but not the entir reason
[10:44:02] <Tom_itx> if it's not in the gcode, it's in the machine
[10:44:13] <zeeshan> when it does the microlift of .010, it needs to plunge back down 0.010, but the plunge feedrate is set to 5 ipm
[10:44:19] <zeeshan> so it suddenly wants to slow from 200 to 5 ipm
[10:44:29] <zeeshan> wait lemme check if thats the case in the gcode
[10:45:06] <Tom_itx> maybe the TP isn't handling that sudden change in feed right
[10:45:12] <zeeshan> NM
[10:45:24] <zeeshan> that plunge feedrate only affects the very first plunge
[10:45:24] <zeeshan> thats it
[10:45:25] <PetefromTn_> Tom_itx like I said earlier I experienced almost the exact same behaviour in many programs on Haas mills
[10:45:46] <Tom_itx> i'd certainly look at the post then
[10:45:55] <zeeshan> to me this seems like
[10:46:01] <zeeshan> i have point to point path blending enabled
[10:46:42] <t12> post the gcode?
[10:48:21] <zeeshan> gimme a min
[10:48:30] <zeeshan> pasting the gcode in my browser crashed it
[10:48:31] <zeeshan> haha
[10:48:34] <t12> lol
[10:49:37] <zeeshan> https://www.dropbox.com/s/qq0uqg06syysx9o/thedrip_caliper_side_facing.ngc?dl=0
[10:49:39] <zeeshan> itll have to be a dl
[10:49:40] <zeeshan> =/
[10:52:43] * Tom_itx declines the offer
[10:56:57] <Roguish> zeeshan. what's 'backfeed'
[10:57:14] <zeeshan> the tool lifts 0.010 in z
[10:57:21] <Roguish> why
[10:57:28] <zeeshan> so its not rubing
[10:57:34] <zeeshan> and returns back to the original spot
[10:57:58] <Roguish> ok, not sure why it would do that, but, ok
[10:58:06] <zeeshan> imagine this
[10:58:08] <zeeshan> you just cut a slot
[10:58:34] <zeeshan> thats slightly wider than your tool..
[10:58:46] <zeeshan> how would you return to the beginning of the slot in the shortest amount of time?
[10:58:54] <zeeshan> without rubbing the tool against the slot walls and slot floor?
[10:59:04] <Roguish> ok, i get it now. thanks
[10:59:15] <zeeshan> there is always deflection so you want to clear at least a couple thou
[11:00:05] <Loetmichel> MAAAAN why is it always on sundays? Washing machine is just tumbling/pumping the grey water out... *UUUUUUUOOOOOOOUOUOUUOUOUOUOUOUOOOOOOOOO* The shaft of the grey water pump rattles about in the worn bearing... where do i get a new pump now?
[11:00:06] <Roguish> r u running mastercam?
[11:00:16] <zeeshan> ya
[11:00:35] <Roguish> what version? what post?
[11:00:45] <zeeshan> x8
[11:00:47] <zeeshan> custom post
[11:00:52] <Roguish> for lcnc?
[11:00:55] <zeeshan> ya
[11:01:12] <zeeshan> i still have a small bug in it where it posts subroutines after the main code
[11:01:31] <zeeshan> and 0 feed error when doing multiple drill holes using subroutines
[11:01:40] <zeeshan> but those are the only ones i know that i ened to fix when i get some time
[11:02:38] <Roguish> i've modified a post for X5, but never ventured near the subroutines.
[11:02:53] <zeeshan> the post is poorly setup
[11:02:56] <zeeshan> when you compare it with hsmworks
[11:03:23] <Roguish> figures. mastercam is old, probably carries lots of baggage.
[11:04:54] <zeeshan> id like to try hsmworks
[11:04:56] <zeeshan> but $
[11:05:23] <zeeshan> in my opinion hsmworks is better :P
[11:07:57] <zeeshan> the problem with mastercam is it covers all types of machines
[11:08:03] <zeeshan> so it is pretty complex to use and setup
[11:10:43] <t12> hsmxpress is decent for flat stuff
[11:11:08] <zeeshan> i usually send flat stuff out for laser cutting
[11:11:09] <zeeshan> lol
[11:11:11] <zeeshan> not worth machining!
[11:11:22] <t12> by flat i mean not doing curves in Z mainly
[11:11:24] <zeeshan> ill finish machine here if its got a crazy tolerance hole
[11:11:27] <zeeshan> o
[11:17:01] <zeeshan> PetefromTn_: youve done thread milling?
[11:18:07] <PetefromTn_> yeah I have
[11:18:29] <zeeshan> if i want to make 1/4-20 holes , m6x1 and larger
[11:18:39] <zeeshan> which single point thread mill would you recommend?
[11:18:47] <zeeshan> im really thinking of keeping one dedicating tool for thread milling
[11:18:51] <PetefromTn_> I have asked the same question
[11:18:54] <zeeshan> cause it avoids setting up rigid tap
[11:18:56] <zeeshan> hehe
[11:18:59] <PetefromTn_> the ones we used in the shops
[11:19:05] <PetefromTn_> were the insert type
[11:19:12] <PetefromTn_> multi tooth threaforming mills
[11:19:24] <PetefromTn_> but they did have a single flute one
[11:19:33] <PetefromTn_> and used it for a lot of threads.
[11:19:41] <PetefromTn_> I know lakeshore carbide has some
[11:19:55] <Erant> zeeshan: Why don't you want rigid tapping?
[11:20:06] <zeeshan> Erant: less tools to keep ready
[11:20:08] <PetefromTn_> for 1/4-20
[11:20:20] <PetefromTn_> you are better off just tapping most likely
[11:20:23] <zeeshan> erant i have only 1 tap holder , so it means i have to set it up for whatever tap im using
[11:20:26] <Erant> They're so expensive though.
[11:20:28] <zeeshan> usually its set for 1/4-20
[11:20:34] <Erant> Ah, fair enough.
[11:20:48] <Erant> I was just going to get collets.
[11:20:49] <zeeshan> if i could have another tool that always holds a single point thread mill, even though its slower
[11:21:01] <zeeshan> i know i can call up thread milling in the software and use this tool every time
[11:21:06] <zeeshan> for almost any possible thread
[11:21:30] <zeeshan> Erant: you should still have about .015 thou float at least in the axial direction
[11:21:33] <zeeshan> for rigid tapping
[11:22:01] <Erant> I heard that, extends tool-life.
[11:23:17] <Erant> I just wanted better control of my spindle, and I happen to get position control out of it.
[11:24:23] <PetefromTn_> https://www.maritool.com/Cutting-Tools-Thread-Mills-Single-Thread-Forms/c78_135_381/index.html
[11:25:35] <zeeshan> not sure which one to go with :D
[11:25:52] <Erant> Huh. That's a bunch cheaper than I remember them being
[11:26:00] <PetefromTn_> those are reasonably priced I think..
[11:26:02] <Tom_itx> zeeshan ever try fusion 360?
[11:26:18] <zeeshan> Tom_itx: nop
[11:26:20] <zeeshan> looks garbage
[11:26:25] <Tom_itx> it's free
[11:26:40] <Tom_itx> i'm kinda anxious to see catia's post
[11:26:45] <Tom_itx> but i'm not there yet
[11:26:51] <zeeshan> learning it isnt free
[11:26:53] <zeeshan> takes time :P
[11:26:55] <PetefromTn_> seems like the .240 dia one would be good
[11:27:08] <Tom_itx> not worth the effort?
[11:27:11] <PetefromTn_> .625 max depth
[11:27:23] <Tom_itx> that .010 lift shouldn't be happening unless you tell it to
[11:28:04] <aventtini6> zee first test run
[11:28:05] <aventtini6> https://www.youtube.com/watch?v=i7U1iJhtDdI
[11:28:08] <aventtini6> :)))
[11:28:21] <zeeshan> Tom_itx: i am telling it to!
[11:28:41] <zeeshan> aventtini6: holy cow thats a big part
[11:28:42] <zeeshan> :D
[11:28:47] <Tom_itx> wtf for?
[11:28:52] <zeeshan> so it doesnt rub
[11:28:52] <Tom_itx> you don't need it there
[11:29:00] <zeeshan> thats how basic adaptive clearing tool paths work
[11:29:03] <zeeshan> they always lift on the back stroke
[11:29:32] <aventtini6> yap
[11:29:34] <PetefromTn_> mastercam has some pretty impressive clearing toolpaths...
[11:29:39] <aventtini6> i have a biger one
[11:29:40] <Erant> PetefromTn_: The .120 would allow you to do #8 and #10 threads...
[11:29:42] <aventtini6> 750 kg
[11:29:42] <Tom_itx> wtf with the rubber gloves?
[11:30:00] <PetefromTn_> Erant as I said before I would just tap holes that small
[11:30:49] <zeeshan> yea i need only m6 and above
[11:30:54] <Tom_itx> zeeshan, so it moves away in x or y and also lifts?
[11:31:01] <Erant> Yeah, .33" deep isn't very deep at all
[11:31:04] <PetefromTn_> for milling holes larger than say 3/8 or so need a lot of spindle torque to rigid tap so thread milling comes into its own there IMHO
[11:31:12] <Erant> Be good for blind holes, I guess.
[11:31:56] <zeeshan> tom it moves away from the walls also
[11:32:32] <Tom_itx> looks like your mister is working good
[11:32:50] <aventtini6> i need to cut all the way down
[11:32:52] <aventtini6> :)))
[11:33:25] <aventtini6> i have for sale a 4 axis if some one wants
[11:33:31] <zeeshan> the mister is garbage
[11:33:32] <Tom_itx> hah, a mastercam training video pops up after yours https://www.youtube.com/watch?v=YuNuB2IT2Ww
[11:33:34] <aventtini6> 1000mm diameter
[11:33:36] <zeeshan> with that md7 bullshit in it
[11:33:40] <zeeshan> or whatever that overly expensive oil is
[11:33:51] <zeeshan> mister is good, but lubricant is garbage
[11:33:55] <zeeshan> it provides no cooling at all
[11:34:28] <PetefromTn_> Here's a stupid question for you home improvement guys
[11:34:45] <PetefromTn_> I just laid down tile in my downstairs bathroom and into the laundry room
[11:34:52] <PetefromTn_> and I got a brand new toilet I need to install
[11:35:03] <PetefromTn_> I am putting in the new flange for the drain
[11:35:26] <PetefromTn_> would you typically grout all the tile BEFORE you set the toilet or after?
[11:35:35] <Tom_itx> before
[11:35:37] <Tom_itx> for sure
[11:35:40] <PetefromTn_> why?
[11:35:44] <Tom_itx> then it's sealed
[11:35:57] <Erant> Can't grout underneath the toilet...
[11:35:57] <PetefromTn_> what is sealed?
[11:36:03] <Tom_itx> ^^
[11:36:32] <Erant> And if there's no grout, water can get in there.
[11:36:36] <Erant> And bad shit happens.
[11:36:37] <PetefromTn_> I realize you can't grout under the toilet but I figured it would not matter really..
[11:36:47] <PetefromTn_> grout is NOT waterproof
[11:36:47] <Tom_itx> invariably moisture will be under the toilet
[11:37:03] <Tom_itx> and creepy stuff will grow in the cracks
[11:37:14] <Tom_itx> no but it's better than nothing
[11:37:17] <PetefromTn_> that is probably true
[11:37:20] <Tom_itx> and you can get a sealer for it
[11:37:23] <Tom_itx> i used it
[11:37:27] <PetefromTn_> yeah I bought the sealer
[11:37:38] <Tom_itx> doubt it works all that well
[11:38:10] <Tom_itx> besides you'll have one less thing to grout around
[11:38:42] <PetefromTn_> heh I figured I would have one less area to grout if I did it after I set the toilet
[11:38:59] <Erant> I wonder how well this works for hardening shit: http://www.banggood.com/5V-12V-ZVS-Induction-Heating-Power-Supply-Module-With-Coil-p-1015637.html?utm_source=google&utm_medium=cpc&utm_campaign=Celc-ad-rm-DM-ZVSHeat&utm_content=hazel&utm_design=25&gclid=CNOgivSricsCFQYIaQod44gOzQ
[11:39:13] <zeeshan> erant thats cheap
[11:39:13] <zeeshan> lol
[11:39:38] <Erant> Seems to get stuff to red-hot. Pulls about 100W
[11:39:42] <Tom_itx> PetefromTn_, especially in humid Tn
[11:41:02] <PetefromTn_> humid TN?
[11:41:02] <Tom_itx> kinda small
[11:41:11] <Tom_itx> yeah even worse in Fl
[11:41:35] <PetefromTn_> we do get some humidity during the height of the summer but I never considered this place Humid really..
[11:42:01] <yasnak> whos from florida?
[11:42:16] <PetefromTn_> define From
[11:42:24] <yasnak> haha, okay who was relocated
[11:42:42] <PetefromTn_> I lived and grew up in Florida
[11:42:55] <PetefromTn_> have lived here in tennessee for 15 years or so
[11:43:07] <PetefromTn_> now sold my home and am currently working on moving BACK to Florida
[11:44:07] <Tom_itx> you got a job lined up there?
[11:44:25] <PetefromTn_> not yet
[11:44:31] <PetefromTn_> my wife already has a job there
[11:44:44] <PetefromTn_> working for the same people she worked for when we lived there
[11:45:14] <PetefromTn_> there do seem to be quite a few possibilities for me tho including several cool race shops and not a small amount of custom cabinet shops...
[11:45:47] <zeeshan> man this cant be right
[11:46:06] <zeeshan> fswizard is saying 0.003" ipt 250 sfm for machining 304
[11:46:09] <zeeshan> thats 31 ipm
[11:46:10] <PetefromTn_> I am more concerned with getting into a house and getting my machines back up so I can continue my business down there as well as getting my house updates finished and my household goods packed up.
[11:46:34] <Tom_itx> zeeshan keeps it moving so it won't work harden
[11:46:44] <Tom_itx> that's what kills it
[11:46:48] <zeeshan> hm
[11:46:55] <zeeshan> i really gotta play with ss more often
[11:46:59] <zeeshan> a lot of shops machine it no problem
[11:47:16] <Tom_itx> it's all in figuring out the feeds
[11:49:21] <Tom_itx> zeeshan, working my way thru that list of dwgs
[11:49:40] <yasnak> 250 sfm?
[11:49:47] <yasnak> what kind of em?
[11:49:49] <zeeshan> Tom_itx: cad nerd
[11:49:55] <zeeshan> yasnak tialn carbide
[11:50:00] <Tom_itx> not much else to do here
[11:50:19] <yasnak> what kind of form are you milling and dia of em?
[11:50:37] <yasnak> 304 sucks but with the right speeds/feeds its not bad
[11:50:48] <yasnak> just really gummy and workhardens so fast
[11:51:20] <zeeshan> yasnak: not machining anything specific
[11:51:22] <zeeshan> general talk
[11:51:28] <yasnak> ah
[11:51:29] <zeeshan> actually another thing, i always hear people saying 4 flute is no good in al
[11:51:32] <yasnak> yeah 250 seems a bit fast
[11:51:35] <zeeshan> but is that really true?
[11:51:42] <yasnak> depends on the size of em
[11:51:48] <yasnak> need room for chips to get loose
[11:51:50] <zeeshan> my experience with 4 flute without any lubrication for al has been instant snapped end mill
[11:51:55] <zeeshan> 3/8
[11:52:01] <Tom_itx> zeeshan they say that because of the high chiploads and no room to evacuate them
[11:52:15] <zeeshan> ive also snapped a 3 fluter
[11:52:17] <yasnak> how are you cutting it? slots? side?
[11:52:26] <zeeshan> id like to only do hsm tool paths
[11:52:28] <Tom_itx> i like 2 for Al
[11:52:36] <yasnak> yeah i use 2ft
[11:52:44] <zeeshan> mari recommends 3 flut
[11:52:50] <yasnak> or insert mills with sharp as hell inserts
[11:52:55] <Tom_itx> i don't like 3 for much of anything
[11:53:24] <Tom_itx> A: you can't put a mic on em
[11:53:31] <Tom_itx> B: you can't put a mic on them
[11:53:35] <yasnak> but i run 2ft and 4ft. 2ft for al just for chip evacuation. 4ft for stainless.
[11:53:44] <yasnak> sure ya can, v-mic
[11:53:53] <Tom_itx> if you have one
[11:53:58] <yasnak> oh, my bad
[11:54:03] <Tom_itx> heh
[11:54:09] <Tom_itx> could cmm it
[11:54:19] <Tom_itx> but that's kinda overkill
[11:54:27] <zeeshan> if i use 3 flute, i can .625doc, .075 woc, 3100 rpm (spindle limited) and 58 ipm
[11:54:37] <zeeshan> would be nice..
[11:54:46] <yasnak> i just see no use and since 2,4 are standard there is a cost faster involved when we blow 50 pounds of carbide a month
[11:55:13] <zeeshan> i need a 6000 rpm spindle
[11:55:15] * zeeshan looks at pete
[11:57:29] <yasnak> i run our 0.375 4ft ems in al @ 14500 rpm (15k 40taper) w/0.1 stepover and full depth of cut
[11:57:58] <yasnak> comes out around 600 sfm but thats with fully hsm paths
[12:03:27] <Tom_itx> yasnak, do you bother to sharpen the carbide em?
[12:04:07] <Tom_itx> at that point it's almost better to use insert cutters
[12:04:33] <yasnak> if they are used on just the tips then yeah, we've got a rollomatic i run them in. do that whenever we have a huge amount of one kind (mainly 0.5+)
[12:04:56] <zeeshan> yasnak: for al?
[12:04:59] <zeeshan> nice
[12:05:01] <yasnak> but I personally, unless its some expensive custom tool, do not regrid od's as it fucks everyone up on the machines
[12:06:13] <MrSunshine> https://scontent-ams2-1.xx.fbcdn.net/hphotos-xpf1/v/t34.0-12/12767270_10153932919168648_363503297_n.jpg?oh=367106fc7d6d3e07941b49374f3a7efb&oe=56CCCAA0 delidded my first cpu! .. or its the 3rd .. the other two broke :P
[12:06:15] <zeeshan> i love watching chips fly :p
[12:06:31] <zeeshan> when you file some steel by hand
[12:06:32] <Tom_itx> don't watch too close
[12:06:37] <zeeshan> you really appreciate chips flying
[12:06:38] <zeeshan> :D
[12:07:02] <zeeshan> https://www.youtube.com/watch?v=6mlxRMz7qw4
[12:07:04] <zeeshan> lets rock on
[12:09:36] <Erant> 'bout to make some HDPE fly. God that stuff machines.
[12:09:45] <zeeshan> haha
[12:10:04] <Tom_itx> rates right there with machinable wax
[12:10:34] <zeeshan> i really regret doing my masters in metal forming
[12:10:41] <zeeshan> im more interested in machining :/
[12:10:42] <Tom_itx> why?
[12:10:54] <Tom_itx> go back and do it over
[12:10:57] <zeeshan> i took courses in machining
[12:11:03] <zeeshan> i liked it a lot more :P
[12:11:10] <zeeshan> cant, im almost half way thru
[12:11:19] <yasnak> metal forming might get you in the door faster
[12:11:20] <Tom_itx> i'd love to see the metal printer they have at the skool
[12:11:25] <yasnak> you can learn machining on the job
[12:11:27] <zeeshan> yasnak: i already work full time
[12:11:28] <zeeshan> :P
[12:11:39] <Tom_itx> zeeshan's always looking for more work
[12:11:51] <yasnak> lol
[12:11:56] <zeeshan> most of the work i do at eaton is sheet metal forming
[12:11:57] <yasnak> one of those huh? im the same way
[12:13:37] <yasnak> at shop now, going to be setting up the 5 axis and was thinking about doing a periscope type livestream
[12:13:46] <zeeshan> do it
[12:13:46] <zeeshan> :P
[12:17:05] <zeeshan> https://www.youtube.com/watch?v=RZB8W81ae_g
[12:17:07] <zeeshan> rofl
[12:17:15] <zeeshan> im reading a thread where theyre trying to blame mastercam for this
[12:17:18] <pink_vampire> http://www.amadamiyachi.com/products/laser-welding/lw-power-supplies
[12:21:43] <yasnak> eh, new programmer had a post that didn't translate the safe planes correctly
[12:21:58] <zeeshan> doesnt look the clearance plane was set
[12:22:06] <yasnak> didn't know how to fix it and edited each one manually until he told me. he did the same thing
[12:22:30] <zeeshan> i need to learn fbm tool paths in mastercam
[12:22:37] <zeeshan> it literally generates all the tool paths for you
[12:22:53] <yasnak> yeah, if you have models that are correct
[12:23:01] <zeeshan> yes
[12:23:07] <yasnak> if they're modeled very poorly the cam software will do all sorts of odd shit
[12:23:19] <zeeshan> it still feels better to do it by hand
[12:23:21] <yasnak> which brings me back to...engineers. i hate them
[12:23:22] <zeeshan> to catch mistakes
[12:23:34] <zeeshan> dont hate us :{
[12:23:54] <yasnak> sadly with 5axis you dont have much a choice. sometimes your tool is inside on an angle and your balls are so far up your throat...
[12:24:13] <Tom_itx> yasnak, what cad cam do you use on your 5 axis?
[12:24:21] <yasnak> powermill
[12:24:31] <yasnak> been playing with hsmworks though
[12:25:20] <yasnak> imachining rep is calling more than my gf. honestly, if it posts crap code i dont want it. too much a risk
[12:25:30] <Tom_itx> a shop around here was looking at this http://www.nccs.com/products/ncl.html
[12:26:30] <yasnak> when you buy these machines youre looking at 500k+. if its your first i'd ask the manufacturer what to use as they should know. another couple grand isn't going to close up shop after that pricetag
[12:26:55] <Tom_itx> everybody around here uses catia
[12:27:28] <Tom_itx> but it's 75k per
[12:27:37] <yasnak> we do solidworks and their epdm software for rev control and workflows.
[12:28:00] <Tom_itx> they're quite similar
[12:28:09] <Tom_itx> catia has alot more features i think
[12:28:17] <yasnak> epdm is a flaming pos. the licensing is crap
[12:28:29] <Tom_itx> and it has it's own post
[12:29:23] <Tom_itx> probably 95% aircraft machining around here
[12:29:29] <Tom_itx> a little agri
[12:29:50] <zeeshan> yasnak: why powermill
[12:30:16] <yasnak> eh, i've used partmaker for years as i started machining on swiss machines
[12:30:36] <Tom_itx> force of habit...
[12:30:49] <yasnak> and powermill somewhat integrets into partmaker. same commands and controls
[12:31:06] <zeeshan> yasnak: i ask cause ive been looking at the 5 axis tool paths for mastercam
[12:31:14] <zeeshan> and ive always heard power mill is better
[12:31:16] <zeeshan> but no one says why =/
[12:31:24] <yasnak> yeah, but honestly its not bad. best part is my sales rep knows how to machine and is a god when it comes to complex posts. i have posts with clearance routines and it gets a bit overkill sometimes
[12:31:57] <Tom_itx> how do you keep track of each machine post?
[12:40:51] <Denkishi> Quick question, should the end stop adjusting screws hit the limit switch right at the black button, or utilize the extention arm for cushion? (If that even makes sense)
[12:41:24] <Tom_itx> use the arm, that's what it's for
[12:41:45] <Denkishi> Pic for hopefully some clarity: http://i.imgur.com/Ws2cE6Y.jpg
[12:42:04] <Denkishi> That
[12:42:48] <Denkishi> That's what I figured. I was just probing to see if it made a delta style 3d printer harder to cal
[12:45:11] <CaptHindsight> what breaks first when over-traveled? The plastic wood screw holder or the switch?
[12:47:12] <Denkishi> Plastic I'd say. But I already fucked it up and put the wrong size screw in when i was building it :/
[12:48:47] <witnit> Im sure you could re-engineer it so your switch in not in line with your travel but adjacent to the travel, so in the case of an overrun it simply passes by the switch
[12:49:24] <witnit> *is not in line*
[12:49:53] <CaptHindsight> sounds suspect
[12:50:10] <Tom_itx> zeeshan how would you approach drawing the left end of the one on P21?
[12:53:01] <os1r1s> Denkishi Is that your orion?
[12:53:42] <Denkishi> rostock max v2
[12:53:52] <os1r1s> Denkishi Ahh, ok. I have both
[12:54:05] <witnit> CaptHindsight: what is suspect?
[12:54:32] <os1r1s> Denkishi On the orion there is no lever and it hits the button directly
[12:54:34] <os1r1s> fwiw
[12:54:58] <zeeshan> Tom_itx: the one with the .5" slot?
[12:56:04] <CaptHindsight> witnit: then you won't hear the sound of plastic cracking. It's a strong visual and audible indicator like a tamper proof seal.
[12:56:35] <witnit> ha yes indeed
[12:57:10] <Denkishi> os1r1s, I assume the hard end of the stop is a bit more rigid, or dampened?
[12:57:23] <Denkishi> on the orion..
[12:57:46] <witnit> I found with limit and home switches is best to put them anywhere excect directly in the path of a moving slide.
[12:57:54] <witnit> except*
[12:58:29] <witnit> http://i1115.photobucket.com/albums/k550/Michael_In_California/CNC%20build/P9220015.jpg
[12:58:41] <witnit> descent example
[12:59:08] <Denkishi> But right now, when I do an "all" in MatterControl, it's slamming those limit switches pretty hard. And in my defence, I followed the directions lol. I was just curious if there was some reason I was missing that they did it that way.
[13:03:33] <witnit> hmm, soo, it makes... "toys" lel http://ecx.images-amazon.com/images/I/4196NI2nGEL.01_SL500_.jpg
[13:04:41] <Jymmm> looks like someone got screwed
[13:05:26] <witnit> "No more embarrassing trips to the market!"
[13:05:47] <witnit> Oh the things I have seen made in shops..
[13:10:32] <Tom_itx> zeeshan, no
[13:10:35] <Tom_itx> i got it though
[13:10:53] <Tom_itx> the one with the 120 deg angle end on a 60 deg slope
[13:11:24] <Tom_itx> err yeah it has a .5 slot
[13:11:57] <Erant> Time to go make some annoyingly static chips.
[13:13:42] <witnit> Erant: what material?
[13:29:05] <zeeshan> lol erant
[13:29:09] <zeeshan> i know the feeling :P
[13:49:28] <Denkishi-> What's a stable 12/24V 30+A power supply one of ya'll would reccommend?
[14:00:12] <Jymmm> 2x 12V@60A =)
[14:01:53] <os1r1s> Denkishi- No. It isn't dampened or rigid
[14:02:44] <os1r1s> Denkishi- Its the same
[14:02:49] <os1r1s> Denkishi- And works fine
[14:20:20] <witnit> Anyone used these before? http://www.a-m-c.com/download/datasheet/be25a20.pdf
[14:21:42] <gregcnc> just set up a smaller pair on my lathe
[14:22:32] <witnit> I had some motors laying around with no amps, this I expect to work on it, but when I tried my motor it seemed to hold and move some with test/offset pot but I was expecting the motor to drive away in one direction when I applied ref+ instead it just bumps over some and holds
[14:23:08] <witnit> gregcnc: brushless then?
[14:23:12] <gregcnc> no
[14:23:46] <witnit> all I have ever used were brush systems, so I am a bit unsure what to expect with this.
[14:23:54] <gregcnc> is commutation setup correctly
[14:25:12] <witnit> doubtful, I was expecting it to work with encoder
[14:25:16] <witnit> and nothing else
[14:25:19] <gregcnc> brushless isn't any different except you have to connect hall sensors
[14:25:28] <witnit> but I am unsure the effects of halls
[14:25:51] <gregcnc> hall sensors detect rotor position for commutation
[14:25:53] <witnit> since I never used them before and my motor doesnt have halls on them
[14:26:16] <gregcnc> does the encoder have commutation output?
[14:26:37] <witnit> uhh?
[14:27:05] <gregcnc> some encoders are configured with commutation in addition to incremental
[14:27:13] <witnit> oh, no
[14:27:42] <witnit> so, the encoder attached to the amp is not enough?
[14:27:55] <gregcnc> you probably need to get an encoder with commutation to make life easy.
[14:28:55] <gregcnc> that amp won't do it
[14:29:09] <witnit> what does the ENCODER input on the amp do?
[14:29:28] <gregcnc> it replaces a tachometer in some applications.
[14:29:52] <gregcnc> it's used to derive a velocity signal
[14:29:57] <witnit> hmm, seemings how my motors dont have hall sensors, encoder, or tach, im not sure what to do with them
[14:30:15] <gregcnc> get an encoder with commutation
[14:30:38] <witnit> that sounds like something which would cost more than the motors
[14:31:03] <gregcnc> you need ancoders anyway
[14:31:05] <gregcnc> ?
[14:34:14] <gregcnc> what kind of a motor is it that it has no hall? RC use?
[14:35:49] <witnit> rc?
[14:36:00] <gregcnc> radio control
[14:36:00] <witnit> It currently uses resolvers
[14:36:05] <gregcnc> Oh
[14:36:10] <witnit> but I dont have a way to make sense of a resolver
[14:39:46] <CaptHindsight> where do you find people to do all your work for you for free so that you can make a profit?
[14:40:36] <witnit> You mean like opensource community, the basis of all our own profit?
[14:40:41] <gregcnc> Ask the Waltons?
[14:40:43] <CaptHindsight> I assuming that I have just been contacted by someone from an alternate universe
[14:42:25] <Sync> zeeshan: did subaru already get back to you?
[14:42:35] <CaptHindsight> witnit: who is the "our" in that question? I don't sell any open source software.
[14:42:49] <gregcnc> The big names in servos make drives that can run a brushless with resolver, beyond that I don't know.
[14:42:57] <witnit> who sells opensource software? :P
[14:43:13] <witnit> yeah but those are expensive gregcnc
[14:43:34] <witnit> I make profit on hardware driven by opensource software
[14:43:49] <witnit> probably like everyone else who ever did anything worth selling in here.
[14:45:13] <CaptHindsight> then you're selling hardware
[14:45:32] <Sync> witnit: you apply a signal and measure amplitude of the return
[14:45:34] <gregcnc> Ebay and hope for the best?
[14:45:39] <witnit> wait someone wanted to buy opensource software from you? is what your saying?
[14:45:55] <CaptHindsight> witnit: not at all
[14:46:10] <witnit> hahah i dunno what you are talking about then :P
[14:46:57] <CaptHindsight> witnit: would you design and build custom hardware from free?
[14:47:10] <witnit> Sync: yeah but what i mean is, without buying anything will this work
[14:47:24] <witnit> I could spend money on a something to make use of the resolver
[14:47:38] <witnit> CaptHindsight: no?
[14:48:02] <gregcnc> pico system makes a resolver to incremental, but you needs comm as well
[14:48:47] <witnit> CaptHindsight: I would give away work I already did for free, but not do some project for free.
[14:48:59] <CaptHindsight> witnit: even for someone who thinks of themselves as very very special?
[14:49:08] <witnit> huh?
[14:49:08] <Sync> you could use our servo drives for it witnit
[14:49:40] <witnit> CaptHindsight: i dont know what you are talking about
[14:49:56] <witnit> link me sync
[14:51:21] <gregcnc> some customers are demanding?
[14:52:01] <witnit> im having troubles following what he is talking about
[14:52:05] <CaptHindsight> paying customers
[14:52:13] <CaptHindsight> witnit: it's ok
[14:52:46] <gregcnc> but I spend xxx dollars with you this year, can't you do it for me????
[14:52:47] <CaptHindsight> what are non-paying customers?
[14:53:20] <CaptHindsight> ahh the throw me some free bees type
[14:54:00] <witnit> sync who is "our"
[14:54:09] <CaptHindsight> I send them a box of bees
[14:54:15] <Sync> https://github.com/rene-dev/stmbl witnit
[14:58:10] <zeeshan> sync prolly monday
[14:58:24] <zeeshan> fix my mill!!!!!!!
[14:58:45] <CaptHindsight> zeeshan: send it here
[14:59:16] <Crom> damnbit!!
[15:00:12] <Crom> trying to find a util to create a canned scrollwork snub end. and there ain't nothing out there...
[15:00:25] <Sync> zeeshan: wat broke?
[15:00:28] <witnit> Sync: I was thinking these were 1.7 kW is ok?
[15:00:33] <zeeshan> sync nothing broke
[15:00:33] <CaptHindsight> JT has Mesa boards in stock that Mesa is currently out of
[15:00:37] <zeeshan> u didnt see the machining video?
[15:00:39] <CaptHindsight> thanks JT-Shop
[15:00:39] <Sync> no
[15:00:48] <Sync> witnit: 1.7kW should work
[15:02:11] <zeeshan> https://youtu.be/70rd9fK-UGg?t=205
[15:02:14] <zeeshan> sync watch the motion
[15:02:20] <zeeshan> on the back feed
[15:04:09] <Sync> I don't see anything suspicious
[15:04:17] <zeeshan> it slows down on the corners
[15:04:47] <Sync> ah
[15:05:31] <Sync> ah yeah
[15:06:21] <zeeshan> i think for now im just going to retract
[15:06:24] <zeeshan> rather trhan retrace the path
[15:06:48] <Sync> just use a continuous path around the part?
[15:07:09] <zeeshan> compare my path
[15:07:14] <zeeshan> er my machine vs this one on the left
[15:07:21] <zeeshan> https://youtu.be/XcUTcSbGebY?t=27
[15:07:28] <zeeshan> look at how smooth the backfeed is around that corner
[15:08:34] <zeeshan> something fishy going on :P
[15:09:00] <Sync> hm yeah
[15:09:08] <Sync> is it a demo part or what?
[15:09:22] <zeeshan> nah i was actually working on a friends part
[15:09:28] <Sync> ah
[15:09:30] <zeeshan> starting to use hsm paths now
[15:09:37] <gregcnc> programmed in mastercam?
[15:09:38] <zeeshan> no reason really to be using conventional
[15:09:42] <zeeshan> greg yes
[15:10:38] <Sync> well, the path looks inefficient, somehow
[15:11:14] <zeeshan> its not!
[15:11:32] <gregcnc> it should retract and go the shortest way, but I don't write CAM
[15:11:40] <zeeshan> you can do that too
[15:12:08] <witnit> it seems like excessive wear on the cutters bottom half to take those types of cuts, the machine on left would have better tool life it seems. But Im not a mill guy.
[15:12:11] <gregcnc> the code has no goofing F values in it?
[15:12:29] <zeeshan> greg nop
[15:12:42] <zeeshan> witnit yep the left tool path means longer cutter life
[15:12:45] <zeeshan> and faster
[15:12:48] <zeeshan> and easier on the machine
[15:12:59] <witnit> easier on machine?
[15:13:01] <zeeshan> cause constant chipload is maintained always
[15:13:02] <zeeshan> yes
[15:13:08] <witnit> oh
[15:13:58] <witnit> I was thinking it would require more torque over the length of cut. probably a bad angle for me to judge "easiness on machine"
[15:14:11] <zeeshan> math doesnt lie :P
[15:14:11] <witnit> more consistant at least
[15:14:17] <gregcnc> that machine can easily break 100 of those endmills a day? and be ready to break more
[15:14:18] <Sync> zeeshan: I think volumill would try to hug the coutour
[15:14:35] <zeeshan> the toolpath isnt the prob
[15:14:40] <zeeshan> its something either in my pid
[15:14:44] <zeeshan> or linuxcnc settings
[15:15:19] <zeeshan> i was hoping someone has played iwth g64 here
[15:15:41] <witnit> is your scaling identical for each axis?
[15:15:43] <pcw_home> Can't be PID unless you have way too wide following error limits
[15:15:56] <zeeshan> nah the ferror is set to 0.002
[15:16:07] <zeeshan> okay so not pid
[15:16:08] <pcw_home> so not tuning/PID
[15:16:17] <zeeshan> witnit yes
[15:16:46] <zeeshan> maybe the cam is outputting too much line segments?
[15:16:56] <witnit> I thought maybe you had a max velocity set for one axis and not the other causing the machine to slow for curvature
[15:16:59] <zeeshan> hmm lemme try turning on the line filter on
[15:17:44] <zeeshan> current prog is 464kb as is,
[15:18:07] <CaptHindsight> are you sure that you used big enough wire?
[15:18:18] <zeeshan> if i turn on line/arc filtering on xy only, with minimum arc radius set to 0.005, and maximum arc radius set to 100, and total tolerance set to 0.001
[15:18:28] <zeeshan> the program size drops to 112kb
[15:18:29] <zeeshan> hmm
[15:18:46] <zeeshan> the little line segments might be overwhelming the controller?
[15:19:15] <CaptHindsight> the old planner only looked ahead by one move
[15:19:38] <CaptHindsight> I forget how far ahead the new one looks
[15:19:51] <CaptHindsight> maybe one of the devs will chime in
[15:20:59] <zeeshan> theres a setting for it
[15:21:36] <zeeshan> ARC_BLEND_OPTIMIZATION_DEPTH = 50 - Look ahead depth in number of segments.
[15:21:48] <zeeshan> # n = v_max / (2.0 * a_max * t_c) #
[15:21:49] <zeeshan> :P
[15:22:19] <CaptHindsight> how many is your CAM putting out in the areas of concern?
[15:22:40] <Sync> 9001
[15:24:26] <zeeshan> 200/(2*10*0.00025)
[15:24:47] <zeeshan> oh ips
[15:25:39] <zeeshan> 3.3333/(2*10*0.00025)
[15:25:44] <zeeshan> 666
[15:25:46] <zeeshan> hmm
[15:25:52] <zeeshan> my current look ahead is set to 50..
[15:26:16] <Sync> set it to 600? :D
[15:26:33] <zeeshan> If you still see strange slowdowns, it may be because you have short segments in the program. If this is the case, try adding a small tolerance for Naive CAM detection. A good rule of thumb is this: # min_length ~= v_req * t_c # where: # v_req = desired velocity in UU / sec # t_c = servo period (seconds) If you want to travel along a path at 1 IPS = 60 IPM, and your servo period is 0.001 sec, th
[15:27:38] * zeeshan tries
[15:27:55] <witnit> can you recreate the problem manually with "long segments"
[15:28:45] <witnit> just a set of similar paths and different segments and compare when and where the velocity is changing
[15:29:03] <zeeshan> im gonna try that setting first
[15:29:18] <zeeshan> and then use the tolerance method in cam
[15:31:25] <gregcnc> what is you rapid on that machine?
[15:31:29] <zeeshan> 200ipm
[15:31:35] <zeeshan> okay i can see right away with tolerance method
[15:31:44] <zeeshan> its combining all those little lines into arcs
[15:31:47] <zeeshan> very cool
[15:33:18] <witnit> if you ran this same job at 10% you probably wont see any speed loss comparing it to a linear motion. I would suspect its not keeping up with trajectory planning.
[15:33:42] <gregcnc> did the other guy having this problem with breaking endmills on inside corners get it figured out?
[15:33:55] <gregcnc> he was also slowing way down in corners
[15:34:38] <zeeshan> it doesnt seem to be a problem at 43ipm
[15:34:44] <zeeshan> but i can suspect it will become a problem at higher speeds
[15:35:13] <zeeshan> im really excited to test these thigns!
[15:36:51] <witnit> does it do circles at a high speed?
[15:37:45] <zeeshan> ill try that out too
[15:37:47] <zeeshan> sec going to machine
[15:40:26] <witnit> I would assume it can do a circle at high speed but when it switches to a multi-segmented curve/arc its not keeping up. Ohh i need to learn so much more about this stuff, everything I say is just guesses ahahahah
[15:48:08] <zeeshan-mill> warm up ...
[15:48:19] <witnit> *cracks knuckles*
[15:55:05] <zeeshan-mill> almost done :P
[15:55:13] <zeeshan-mill> i am curious about circles at high speeds
[15:55:19] <witnit> Im patiently waiting for your research results
[15:55:32] <zeeshan-mill> haha
[15:55:40] <zeeshan-mill> i think the first step is the circle
[15:55:45] <zeeshan-mill> cause its a simple path
[15:56:16] <witnit> you have Z axis?
[15:56:47] <Tom_itx> G6.2
[15:56:59] <Tom_itx> looks interesting
[15:57:31] <zeeshan-mill> yes witnit
[15:57:32] <zeeshan-mill> its 3axis
[15:58:04] <Tom_itx> http://www.mmsonline.com/articles/tool-path-strategies-for-high-speed-machining
[15:59:01] <witnit> I was wondering if you changed your program from x-y to X-z or Y-Z and see if one of the two axis are funny. but more than likely if you can do fast circles its probably the trajectory planning which is slow or something.
[16:02:40] <zeeshan-mill> okay
[16:02:43] <zeeshan-mill> doing a 5 " circle
[16:02:48] <zeeshan-mill> er 3" circle at 200 ipm
[16:02:57] <zeeshan-mill> it drops massive speed at the quadrants
[16:03:15] <zeeshan-mill> at each half quadrant
[16:03:29] <witnit> okay, time for a smart person to come explain :P
[16:03:36] <zeeshan-mill> lol
[16:07:44] <witnit> your ngc file?
[16:10:37] <zeeshan-mill> nm fixed it
[16:10:39] <zeeshan-mill> it was the gcode
[16:10:43] <zeeshan-mill> write the circle by hand :P
[16:10:43] <witnit> ;)
[16:11:27] <gregcnc> I saw going to ask if it was a single g2 move, but thought ......
[16:15:14] <zeeshan-mill> testing the old prog :P
[16:18:18] <zeeshan-mill> okay adding tolerance didnt help
[16:20:03] <zeeshan-mill> increased ARC_BLEND_OPTIMIZATION_DEPTH = 50 to 670
[16:20:15] <zeeshan-mill> seemed like it helped but prob still there
[16:20:57] <gregcnc> interesting, how fast is the PC on that machine?
[16:21:13] <zeeshan-mill> how do you want me to quantify that
[16:21:16] <zeeshan-mill> like cpu speed?
[16:21:24] <zeeshan-mill> this is using a mesa 7i77 and 5i25 combo
[16:21:45] <CaptHindsight> in bananas per fortnight
[16:21:46] <gregcnc> if not CPU speed, where is the hangup?
[16:22:24] <zeeshan-mill> g64 is on
[16:22:25] <zeeshan-mill> btw
[16:22:34] <zeeshan-mill> G64 - without P means to keep the best speed possible, no matter how far away from the programmed point you end up.
[16:22:43] <CaptHindsight> zeeshan-mill: have toy asked the devs about the issues and where to poke around?
[16:22:51] <CaptHindsight> toy/you
[16:22:54] <zeeshan-mill> no
[16:23:19] <CaptHindsight> they are pretty helpful and generally have good suggestions fr where to look
[16:24:28] <CaptHindsight> or other code to test it with too see if it's your CAM vs setup or a possible bug
[16:35:50] <Deejay> gn8
[16:36:08] * Tom_itx smacks zeeshan
[16:36:16] * Tom_itx smacks zeeshan with a PID tuning tool
[16:43:51] <CaptHindsight> Tom_itx: cut him some slack, have you seen his hands? :)
[16:46:05] <Crom> hmmm has Duc been here? thinking about his 0-30 code
[17:06:42] <alex_joni> anyone knows any stepper driver chips which are programmable?
[17:07:06] <alex_joni> e.g. you can set microsteps, current limit & such via some interface?
[17:07:31] <alex_joni> (not with resistors, but I2C or similar)
[17:12:25] <pcw_home> some Allegro ones can (SPI)
[17:14:01] <alex_joni> I only want i2c or spi for configuring it
[17:14:08] <alex_joni> I still mean to drive it with step/dir
[17:15:28] <__rob> alex_joni, you can program with the STM dspin ones
[17:16:19] <__rob> fet currents, microsteps etc..
[17:16:54] <__rob> but you can't dynamically change microsteps, you have to put outputs hi-z
[17:17:03] <__rob> still quite nice tho
[17:19:22] <__rob> those ones also have a full motion engine built in for setting target speeds, accel, decel, position etc.. rather then stepping yourself. never used it tho
[17:19:51] <alex_joni> __rob: cheers, looking at L6470 now
[17:21:34] <pink_vampire> hi alex_joni
[17:21:57] <pink_vampire> i think I know
[17:23:26] <pink_vampire> found it
[17:23:27] <pink_vampire> http://www.elmomc.com/
[17:24:43] <pink_vampire> alex_joni: are the admin here?
[17:25:43] * alex_joni is off to bed
[17:25:45] <alex_joni> thanks all
[17:26:22] <pink_vampire> I have a discord server about cnc macining.
[17:26:44] <pink_vampire> maybe you can add it to the topic here
[17:30:25] <pink_vampire> https://discordapp.com/invite/0oAimSwFHdSWZCUl
[17:30:39] <pink_vampire> this is the invite link.
[17:45:05] <Tom_itx> CaptHindsight, haha
[17:46:22] <witnit> wait admin, people admin around here?
[17:47:15] <Tom_itx> not much
[17:48:01] <witnit> this community seems really good about self regulation
[17:48:15] <witnit> also the topic of interest seems to filter out the morons :)
[17:49:16] <XXCoder> yeah here dont get much scrollers and such'
[17:50:13] <witnit> Im quite possibly one of the weakest minded individuals here. Just a try-hard linux user.
[18:00:48] <Jymmm> Shit, I didn't know linuxcnc was a game! But I guess it is... https://www.youtube.com/watch?v=Zs0MTWUkBaQ
[18:02:52] <Jymmm> witnit: Um, why would you say that bout yourself?
[18:02:59] <Denkishi> os1r1s, what bed do you have on the rostock? I have an Onyx HB, Rev 7, but it takes years it seems to even reach 80 :(
[18:03:17] <os1r1s> Denkishi I have the latest one, not sure the version
[18:03:27] <Denkishi> running on 12v?
[18:03:34] <os1r1s> Denkishi But I don't print ABS with it so I don't go that high
[18:03:47] <Denkishi> Fair enough.
[18:03:47] <os1r1s> Denkishi Correct. You can't run that bed on 24v
[18:04:17] <Denkishi> Erm, I heard different for models after rev 3? o.0
[18:05:17] <witnit> Jymmm: I have spent countless hours staring into the abyss of manuals and still things don't click
[18:05:27] <witnit> very aggravating
[18:06:15] <os1r1s> Denkishi Fairly certain it does not. I can ask John next time I talk to him.
[18:08:47] <witnit> I dont think its ever a good idea to trust robot to do something like that
[18:10:23] <witnit> that guy riding around on it like some toy, there has got to be some possibility its just going to smash him into the concrete
[18:12:18] <malcom2073> Though I hear about those arms killing people in the mfg world, more than the hobbiest world... granted there is an order of magnatude or 5 difference between the numbers, but I wonder if anyone has killed themselves just playing with one
[18:12:57] <witnit> im sure of it malcom2073 people do some really stupid stuff
[18:13:09] <malcom2073> And sometimes don't stick it on youtube heh
[18:13:45] <witnit> there was a guy not far from here got the squish from one
[18:14:34] <malcom2073> I almost got one for free, just for the cost of hauling it 500 miles.
[18:14:40] <malcom2073> It scared me too much
[18:14:45] <witnit> I assume he was just setting it up and a motion got triggered unexpectedly but why put yourself in the range of a robot while its waiting to move
[18:15:04] <malcom2073> Yeah, I'd be nowhere in reach anytime power is applied
[18:15:27] <witnit> I paid $100 for a broken motoman :)
[18:15:35] <witnit> works now =D
[18:15:51] <malcom2073> Heh, whatcha use it for?
[18:16:11] <malcom2073> That's the other thing, I didn't have a really good usefor one
[18:16:12] <witnit> I had an engineer come in and help me work out loading system to replace the robot, just a small part fed into a vice then removed
[18:17:00] <witnit> but I had the robot cylcling and he just rolls a stool up beside it and starts measuring things while the bot is cruising around.. im like UHHHH no dood. this thing needs shut off
[18:17:47] <malcom2073> lol
[18:17:49] <witnit> I dont have much faith in things created by humans
[18:18:08] <witnit> ntm the robot was from like 1989 or something
[18:18:16] <witnit> so how safe can it REALLY be
[18:19:00] <witnit> malcom2073: i didnt have a use for one until I got it
[18:19:46] <witnit> imagine this, 10,000 turned parts in lathe, when part is done on one end the robot picks it off, flips it and puts it back in for rear work
[18:20:06] <witnit> or parts come down vibrating bowl and then robot picks them up and deburs a hole
[18:20:35] <witnit> tons of little operations I never thought I would need it for, and it saved me alot of work, but I guess thats for me since I do higher quantity production
[18:21:50] <witnit> originally it was set up for welding, but I mostly use it for part handling and minimal machining
[18:30:40] <Tom_itx> zeeshan around?
[18:31:02] <Tom_itx> take a peek at the one on P28.. i don't see enough dimensions to draw that
[18:32:35] <Tom_itx> well, maybe... but it's sure a horrible drawing
[18:37:14] <CaptHindsight> witnit: what type of robot?
[18:39:05] <CaptHindsight> SCARA, Cartesian, the kind that attacks old people?
[18:40:42] <witnit> like the one in that video
[18:40:44] <witnit> but smaller
[18:41:03] <witnit> could probably do the same thing as that one if that guy were a cat
[18:43:32] <Jymmm> witnit: Ah, but that doesn't make you "weak minded" in the least, actually more the opposite imo
[18:44:52] <Jymmm> Man, this upload is taking F O R E V E R !!!
[18:48:03] <witnit> Maybe if I had more people to work with when learning all this stuff I wouldnt feel so behind the times. I managed to learn most industrial concepts and tools. Its just I dont have any other people or working environments to gain knowledge from. Everyone I work with is familiar with cam driven, screw adjustment based pre WWII technology.
[18:49:08] <Jymmm> witnit: Well, you're in the right place to learn the linux side of things
[18:49:38] <witnit> ha right! I started out YEARS ago in here with a etch a sketch and a couple old motors
[18:50:09] <Jymmm> But do you still have the etch-a-sketch, and does it still work is the big question????
[18:51:00] <witnit> now I have robots integrated with servo driven lathes and linear encoders and oh ladder logic im learning that, and well no, the motors left the etch a sketch and are now on one of my turret lathes :)
[18:51:35] <Jymmm> Well, at least you repurposed them properly =)
[18:52:12] <Jymmm> WOOHOO 40m to go!!!
[18:52:17] <witnit> I can happily say I been blessed to work with a fair different number of mesa cards and can make a machine run without using pncconf and stepconf now -D
[18:52:29] <Jymmm> hahaha
[18:53:01] <witnit> I have wondered how long it will be though before everyone in here becomes VERY sought after
[18:53:31] <witnit> Im sure there a businesses right now trying to find ways to make the switch but lack people familiar with linux to follow them through
[18:53:45] <witnit> a lot of^
[18:54:22] <Jymmm> Linux is, and always will be, a "speciality" and limited in marketability.
[18:54:48] <Jymmm> well, nix more so than linux
[18:54:53] <Jymmm> *nix
[18:58:04] <witnit> Yes but also there are some SERIOUSLY high paying jobs for people who can both linux and do motion controls. I think google is asking for a few right now to develop their flying cars
[18:58:53] <CaptHindsight> Linuxcnc on windows virtualbox host
[18:59:12] <XXCoder> or linux with windows in virtualboxn host
[18:59:25] <XXCoder> or linux with windows in virtualbox
[18:59:47] <CaptHindsight> so the user only sees windows
[18:59:47] <witnit> much like people making the switch from microsoft to host their webservers I think the industrial world could quickly take be taken over with embedded linux and controls we all know quite well
[18:59:48] <malcom2073> I use linux vm's almost exclusivly nowadays heh
[18:59:51] <malcom2073> for my linux needs
[19:00:42] <CaptHindsight> but machine operators and programmers only want Fanuc, Siemens etc
[19:00:47] <witnit> I had my linux server up to host a virtualbox for windows to host quickbooks......
[19:00:51] <witnit> easy to back up tho!
[19:00:52] <XXCoder> linux in windows virtualpc host in linux virtualpc host
[19:00:58] <witnit> and remote access is wondrous
[19:01:11] <XXCoder> think deepest I ever saw was 4 deep
[19:01:13] <CaptHindsight> it's like asking about welders, you're only allowed to pick from Red or Blue
[19:01:19] <malcom2073> XXCoder: It rings a beel, I think I've tried that, and you can't virtualize inside a virtualized OS?
[19:01:29] <malcom2073> bell*
[19:01:55] <malcom2073> I may be remembering wrong, or had done something wrong though heh
[19:02:42] <witnit> Im pretty sure if we all lived a bit closer to one another we would have started a serious machine retro fitting business by now
[19:03:12] <malcom2073> There's a guy who goes to a meet near me who used to do linuxcnc retrofitting
[19:03:16] <malcom2073> as a full time business
[19:03:20] <CaptHindsight> witnit: the used machine business is very depressed right now
[19:03:27] <witnit> he doesnt anymore?
[19:03:31] <witnit> great time to buy!
[19:03:40] <malcom2073> The only market is hobbiests, and *very* small shops. Neither of which have much money
[19:03:47] <malcom2073> Any decent sized shop wants a "proper" control
[19:03:53] <CaptHindsight> when oil is down, used machine sales are down, at least in the USA
[19:04:36] <CaptHindsight> 10 year old machines are just too slow
[19:05:07] <CaptHindsight> shops need machines that can pump out as many parts per hour as possible
[19:05:11] <witnit> It seems to me like the entire mfg world is turning toward automation in every sector, if its an assembly line, painting, or bagging parts
[19:05:22] <CaptHindsight> tool changes need to be a fast as possible
[19:05:22] <malcom2073> Automation is the future
[19:05:32] <malcom2073> The less humans needed, the more money is saved
[19:05:34] <witnit> well i used technology from back in the 40's and still am going faster than most cncs
[19:06:08] <CaptHindsight> we need leaders that are human
[19:06:47] <CaptHindsight> for things to change
[19:06:51] <malcom2073> Yeah
[19:07:07] <malcom2073> But if there is money to be saved by removing a human from the loop, it'l happen
[19:07:26] <witnit> IMO removing all humans from the mfg loop is the ultimate goal
[19:08:05] <malcom2073> You keep a couple humans around for maintenance and repair of course, that's where future jobs are :-D
[19:08:08] <witnit> maybe some day people will not have to spend 1/3rd of their lifetime working at an 8 hour job and humanity can focus on important things, like music and space exploration
[19:08:19] <CaptHindsight> unless you are making humans
[19:08:38] <malcom2073> I leave that job to my wife
[19:08:50] <malcom2073> I jsut attend the kickoff meeting of that particular project
[19:08:56] <witnit> LEL
[19:08:59] <witnit> tooo funnay
[19:09:00] <CaptHindsight> witnit: nah, we didn't want that, we gave the profits from productivity to the already wealthy
[19:12:34] <witnit> I was thinking of another industry linux became a huge competitor in, cell phones.. HUGE market
[19:13:04] <CaptHindsight> it helped keep microsoft out of phones
[19:13:37] <witnit> Someone in this room will be the first one to take EMC to the next level and revolutionize the controls for the mfg industry
[19:14:13] <malcom2073> pathpilot? :P
[19:15:06] <witnit> like the electric car is the underdog today, but not forever
[19:17:57] <bobo__> jymmm just for you ,from just south of SpeedEvils location https://www.youtube.com/watch?v=ZZoXcKiHDag
[19:18:59] <witnit> welp, offf to the shop, later fellers!
[20:01:42] <minibnz> my mill is suffering from noise on the step lines :( thats the only explaination i can come to.. tried to use my diviging head
[20:02:48] <Jymmm> bobo__: HAHAHAHA, that was pretty good. What did he use for "beef stock"? And when he was saying "brown sauce", I though he was saying "BROOM Sauce" =)
[20:02:51] <minibnz> dividing head and cannot get it to do exactly 360' it will do 4 degrees too many or 6 degrees too few.. its not exactly that everytime so i am guessing its noise..
[20:03:26] <Jymmm> minibnz: backlash?
[20:03:36] <minibnz> i have tried increasing the pulse widths on the step signals to no effect.
[20:03:38] <malcom2073> minibnz: Even when running super slow and low acceleration?
[20:03:50] <Jymmm> minibnz: Have a DTI ?
[20:03:58] <minibnz> jymmn its a belt drive and its happening on succsessive moves in the same direction.
[20:04:24] <minibnz> malcom yeah super slow still does it.. slow like 1 rev over 5mins.
[20:04:31] <minibnz> DTI?
[20:04:34] <Jymmm> OMG! The upload has finished!!!
[20:05:16] <Jymmm> minibnz: http://www.mscdirect.com/browse/tn/Measuring-Inspecting/Dimensional-Measuring-Tools/Drop-Test-Indicators-Holders-Accessories/Test-Indicators-Accessories/Dial-Test-Indicators?navid=12107829
[20:06:19] <minibnz> i placed a chunk of material in the jaws moved clock wise to remove any chance of backllash then drilled a hole told it to turn 360' clockwise and see if the drill still lined up with the hole. and it never does. tried tamping with the steps per degree and thats when i get the 4 and 6 offsets.
[20:07:16] <minibnz> jymmn i have a regular dial indicator that i can use once i get close but this is so not even close i can see it as i enter the room that its not lined up...
[20:08:43] <bobo__> Jymmm I don't have any idea . closest I can think of is ask SpeedEvil what John is saying . Check out Johns go-cart
[20:09:18] <minibnz> as i cannot get the steps per degree right. noise is the only thing i can think of that would cause something like missed steps.. i am using a flat ribbon cable from the parrallel port to the stepper board i am going to see if shortening that helps maybe even see if i can sheild it better some how..
[20:11:41] <minibnz> being a standard par port just about every second wire is already a gnd line it might explain why i dont really see this on the other axis.. that said i have noticed a weirdness with the X axis where it will go 1.05mm then 0.95mm when told to move 1mm steps. thought that was the leadscrew being off but it just might be noise..
[20:13:34] <minibnz> when the dividing head is turning and i place a finger on the chuck i can feel it missing steps.. i tried dropping microsteps, increasing microsteps and pulsewidths but nothing seems to help.
[20:13:51] <minibnz> at least i have a decent indicator of the problem..
[20:14:17] <minibnz> time to break out the tin foil.. :)
[20:14:46] <Jymmm> bobo__: who's john?
[20:15:50] <Jymmm> bobo__: I have a 4 ingrediate chicken pot pie recipe, sadly no machine/cnc tools are needed
[20:16:40] <minibnz> while i am at it i will also swap the pin that controlls the coolant pump.. everytime i boot up the coolant pump turns on until the kernel and linuxcnc has started..
[20:17:29] <minibnz> i have it on the BUSY pin which is active low so it defaults high turning on the pump.. will swap that with the led thats much less likely to cause any harm if it turns on by itself...
[20:17:49] <minibnz> thats a trap for young players of the printer ports :)
[20:19:34] <Crom> minibnz, what drivers, and break out board you using?
[20:20:16] <Crom> I have the dreaded YOOCNC board myself, and slowly swapping out that hunk of junk
[20:20:20] <minibnz> ummmmm yeah.. i have some dual pci printer port card. and i forget its been such a long time since i purchased and set that part up..
[20:21:13] <minibnz> the break out board i am using is of my own creation.. its now a combination of arduino module boards, like 3 mosfet drivers and a dual motor driver..
[20:21:38] <minibnz> just about to wire up the motor cotroller to a linaer actuator i purchased off bay to make a ATC out of..
[20:22:15] <minibnz> its 50mm throw @ 150kg of push.. still might need a lever to squash my spring to release the collet
[20:25:54] <minibnz> i only need 5mm of travel in the arbor bolt but i got the 50mm actuator incase i need to use a lever.. i tried a 40mm air piston on shop air @100psi but it wasn't quite enough push it started to move the spring.. this actuator has an extra 35kgs of push and is electric as now i dont have a big compressor it should be quiet.
[20:26:46] <minibnz> i hope its delivered today.. auspost have had it since thursday....its now monday they surely have it on the bike..
[20:30:09] <minibnz> tool holders will be the next thing on the wish list...
[20:42:07] <bobo__> Jymmm: John = doubleboost the guy machining the food. his home is just south of Scotland. in some of his videos he talks about it.
[21:34:56] <Crom> AvE used a lathe on a potato last week
[22:07:46] <Jymmm> bobo__: ah ok
[22:13:46] <evil_ren> crom: messy
[22:16:16] <Crom> very
[22:25:10] <bobo__> I think it started when John = doubleboost was making scrambled eggs by using a battery powered drill motor,and remarked on which brand gave better results
[22:28:11] <Jymmm> lol
[22:29:48] <evil_ren> makita is the best brand for mixing natural peanut butter with a fork
