[00:00:16] <bobo> green for envy
[00:02:12] <roycroft> so do spiral taps work for hand tapping?
[00:02:50] <roycroft> it seems they would have better chip clearance than standard straight taps
[00:03:01] <roycroft> and even when hand tapping that's a problem
[00:03:07] <zeeshan> ive used it by hand
[00:03:10] <zeeshan> but they seem fragile
[00:03:13] <zeeshan> to side loading
[00:03:27] <roycroft> yeah, i can see that
[00:03:46] <zeeshan> i like how the chip
[00:03:48] <zeeshan> comes out
[00:03:51] <zeeshan> and doesnt go in
[00:03:58] <zeeshan> its very useful for tapping on the car.
[00:03:59] <roycroft> in larger sizes, say 3/8" or larger, they're probably pretty sturdy
[00:04:01] <zeeshan> like an oil pan
[00:04:22] <roycroft> but for smaller ones side loading would be a concern
[00:05:05] <roycroft> what about hand tapping with forming taps?
[00:05:09] <bobo> Oh ! Digital Machinist --Vol10,# 1 =spring neat article on scales having sine wave output ----- converting to square wave via "ic-Haus " chip
[00:05:09] <roycroft> is that reasonably doable?
[00:05:36] <zeeshan> i have done thread forming taps by hand
[00:05:40] <zeeshan> they are crazy strong :)
[00:05:47] <roycroft> the chips go nowhere if you use one of those
[00:05:53] <zeeshan> there are no chips
[00:05:55] <roycroft> right
[00:05:55] <zeeshan> it deforms
[00:05:58] <roycroft> which is why they go nowhere
[00:06:05] <zeeshan> actually you make a good point
[00:06:09] <zeeshan> i didnt think about that for oil pan tapping
[00:06:11] <zeeshan> that makes more sense!
[00:06:16] <zeeshan> Good man!
[00:06:36] <roycroft> sometimes i accidently get something right :)
[00:06:47] <zeeshan> i have to tap my oil pan
[00:06:51] <zeeshan> but the problem is
[00:06:54] <zeeshan> the drill chips :)
[00:07:01] <zeeshan> so i guess ill still have to pull it
[00:07:39] <roycroft> edm
[00:07:49] <roycroft> peck a hole
[00:07:53] <roycroft> :)
[00:08:16] <zeeshan> haha
[00:09:42] <bobo> zeeshan see if you can pick up a copy of Digital Machinist , bofore you got a used CNC lathe that weights more than the house
[00:09:56] <zeeshan> lol
[00:11:02] <bobo> the scale article is very good
[00:12:18] <zeeshan> im studying for my exam tomorrow
[00:12:25] <zeeshan> lol one of the things he taught is
[00:12:26] <zeeshan> us
[00:12:33] <zeeshan> "Center drilling - not very common anymore"
[00:12:41] <zeeshan> "Carbide drills are used directly"
[00:12:46] <zeeshan> :(
[00:12:54] <tiwake> wait what
[00:12:55] <zeeshan> damn industry and their big wallets
[00:13:08] <zeeshan> hes saying that its pointless to center drill
[00:13:09] <tiwake> what does center drilling mean?
[00:13:10] <zeeshan> before drilling
[00:13:17] <tiwake> oh
[00:13:29] <zeeshan> http://upload.wikimedia.org/wikipedia/commons/d/df/CenterDrills123456.jpg
[00:13:31] <zeeshan> those things
[00:13:34] <tiwake> spot drill thing so the drill does not wonder
[00:13:40] <tiwake> yeah
[00:13:41] <tiwake> derp
[00:13:45] <tiwake> (I knew that)
[00:14:07] <zeeshan> i just felt sad when he was saying that
[00:14:12] <zeeshan> cause i always use center drilling
[00:14:13] <tiwake> donno what industry they are talking about, but I've been a machinist for ~10 years now and use them flank tons
[00:14:22] <zeeshan> cnc production environment
[00:14:33] <bobo> anyway --what's with the slant bed lathe ? bolt the sucker to the ceiling ! gives you more floor space too
[00:14:34] <tiwake> yeah, CNC
[00:14:42] <tiwake> why would you not use one?
[00:14:43] <zeeshan> bobo: ROFL
[00:14:50] <zeeshan> tiwake: cycle time
[00:14:58] <tiwake> no I mean
[00:15:07] <tiwake> you cant get away from using one... lol
[00:15:18] <zeeshan> you can if youre drilling flat stuff
[00:15:23] <tiwake> dills like to drill sideways
[00:15:23] <zeeshan> cause carbide is stiff enough to not wanter
[00:15:25] <zeeshan> *wander
[00:15:39] <tiwake> who has the money for solid carbide drills?
[00:15:44] <zeeshan> thats why im saying!
[00:15:49] <tiwake> I guess spade drills are not necessary
[00:15:51] <zeeshan> damn industries with their big wallets
[00:16:00] <zeeshan> did you know
[00:16:08] <zeeshan> roughly 5% of the manufacturing cost is tooling
[00:16:08] <zeeshan> lol
[00:16:10] <tiwake> I use spade drills a fair amount, and typically don't center/spot with them
[00:16:24] <roycroft> you folks on this channel have converted me to using spot drills, not center drills, for locating drill holes
[00:16:36] <roycroft> they work so so much better
[00:16:42] <zeeshan> i use both
[00:16:44] <zeeshan> i dont know why
[00:16:49] <tiwake> depends on the thing
[00:16:50] <zeeshan> i guess cause i only have 2 size spot drills
[00:16:56] <zeeshan> oh i know why
[00:17:00] <zeeshan> for drilling centers for the lathe tail stock
[00:17:11] <tiwake> center drills are ... yeah
[00:17:14] <roycroft> yes, but that's a different operation
[00:17:19] <zeeshan> but i still use it to start a hole
[00:17:34] <roycroft> you're drilling for centers, not for drills
[00:17:41] <zeeshan> no even for drills
[00:17:43] <zeeshan> i use it
[00:17:53] <zeeshan> my spot drill is 1/2"
[00:17:55] <zeeshan> i think thats why
[00:18:00] <tiwake> today I machined some airplane parts and use a center drill
[00:18:02] <zeeshan> if i wanna drill a 1/4" hole
[00:18:05] <roycroft> i bought several spot drills
[00:18:09] <zeeshan> it might wander too much (thats what it feels liek for me)
[00:18:15] <zeeshan> nice tiwake
[00:18:25] <tiwake> struts
[00:18:36] <roycroft> it was getting on time to replace my center drills
[00:18:38] <zeeshan> are you ssi's friend? :D
[00:18:42] <roycroft> and i'm not using my little lathe much
[00:18:42] <zeeshan> hes our resident air craft guy
[00:18:49] <tiwake> no idea who that is
[00:19:04] <roycroft> so i figured i'd keep my mostly worn center drills for the lathe, and get spot drills for other uses
[00:19:15] <tiwake> what I made is for a company in seattle.... *shrug*
[00:19:22] <zeeshan> nice
[00:19:34] <tiwake> replacing airplane parts on float planes
[00:21:06] <bobo> the North to Alaska -radial engine people ?
[00:21:20] <tiwake> donno
[00:21:59] <bobo> do they pay in gold flakes?
[00:22:18] <zeeshan> haha
[00:22:23] <zeeshan> youve been watching too much gold rush alaska
[00:22:25] <zeeshan> i love that show
[00:22:32] <tiwake> it was brought to me from a third party... a guy who had been doing other work for them for years. He knew they were looking for a shop to make the parts and knew we were looking for more work
[00:25:43] <bobo> tiwake float plane people are in my "real people" catagory. you might ask for a ride sometime
[00:27:52] <bobo> and a radial aircraft engine just sounds right!
[00:29:03] <tiwake> enh
[00:29:18] <tiwake> I cant see myself flying a piston engine
[00:30:04] <tiwake> not terribly useful for getting places these days it seems... a small 2 seater jet would be lots of fun though :3
[00:30:59] <tiwake> how much does a 2,000 ftlb turbine engine cost these days?
[00:31:25] <tiwake> buy one and make an airplane around it XD
[00:31:33] <bobo> radial aircraft engine---- John deer 2 cylender -- older Harley ----- Winscon V4 ,
[00:31:42] <renesis> use as most awesome spindle motor ever
[00:32:16] <renesis> full afterburner for engraving work
[00:36:59] <bobo> the Digital Machinist article even goes into resolvers
[00:37:32] <bobo> be back later
[01:56:20] * tiwake pokes the lurker wollw
[01:56:39] * wollw pokes tiwake back
[01:56:45] <tiwake> :P
[01:57:21] <wollw> Got a few other things I need to take care of before I get into this more unfortunately.
[01:59:09] <tiwake> I've heard of some cheap G-code things... guess it kinda depends on budget
[01:59:26] <tiwake> how often the machine is used, and who needs to use it
[02:04:59] <wollw> yeah
[03:02:06] <Deejay> moin
[05:07:31] <Cromaglious_> durn it... Am I going to have to buy something to generate 3d code
[05:07:45] <XXCoder> it does seem so far.
[05:07:58] <archivist_herron> use inside rear of skull
[05:09:18] <Cromaglious_> That's broken a bit
[05:09:55] <XXCoder> ?
[05:10:15] <archivist_herron> stop smokin da weed
[05:10:26] <Cromaglious_> I got hit in the head with a hammer in 2000, I have conitive and memory issues
[05:10:58] <archivist_herron> ouch
[05:12:03] <Cromaglious_> CSR for many things... short term is very bad. If I study it enough it starts sticking
[05:13:40] <Cromaglious_> like the other night with r2e4 in using G61 and G63 I remembered it was around G6x something with the constant velosity
[05:14:04] <XXCoder> it sucks when only 3 am option for snacks are walmart or fast food
[05:14:19] <XXCoder> dont feel like fast food and I will never shop at walshit
[05:14:22] <Cromaglious_> I had mach3 running on the winbloz machine and was able to pull up gcodes real quick
[05:15:38] <Cromaglious_> I tend to keep many extra cans of clam chowder (which nobody else in the house will eat and stew which they will
[05:16:19] <Cromaglious_> I used to do tuna, but had to drop that because of purines (gout magnet)
[05:18:48] <Cromaglious_> potato bread, mustard, hot dogs, soup, stew, flat cheese (american processed faux cheese) are my snack foods and hot tea
[05:20:04] <Cromaglious_> hmmm kewlios my new to me logitech wireless mouse works on here...
[05:20:53] <Cromaglious_> got it for free... it was covered in leaked battery.. a little vinegear and it's good to go again
[05:21:35] <XXCoder> darkfield one?
[05:22:46] <Cromaglious_> the pre unity one 810-00215
[05:22:59] <XXCoder> oh
[05:23:07] <XXCoder> I love my dark field mouse
[05:23:16] <XXCoder> I had orginial first version
[05:23:26] <XXCoder> and second one, both with design flaw, got em free
[05:23:38] <XXCoder> this one is third one, and this time no hardware flaws
[05:24:15] <Cromaglious_> V220 notebook gray mouse
[05:24:57] <Cromaglious_> crap range though
[05:25:17] <XXCoder> lol think mines at 5 feet or more
[05:25:35] <Cromaglious_> will not even reach across the living room. The unity one reaches over 30'
[05:26:06] <Cromaglious_> closer to 50'
[05:26:19] <XXCoder> since mines not portable computing device, and facung wall I can't test mouse rante atm
[05:31:07] <Cromaglious_> ahhh it's not the mouse it's the receiver location...
[05:33:20] <XXCoder> heh mines less than one feet away by fault
[05:37:13] <Cromaglious_> if I have it to far back on the computer top it stops working
[05:37:41] <Cromaglious_> I just moved it to the wood shelf now it works acrss the room
[06:21:23] <jthornton> anyone ever make a telescoping cover for a 6" mill vise like this
http://www.dynatect.com/uploads/images/Telaflex-Steel-WayCover3.jpg
[06:24:49] <XXCoder> 6 in?
[06:24:56] <XXCoder> wouldnt leather sheet work fine
[06:25:49] <jthornton> what about the coolant?
[06:25:59] <XXCoder> ah yea
[06:26:24] <XXCoder> that probably is makable with anyone with bender
[06:26:27] <jthornton> the piece of spring steel they give you is too long usually
[06:26:28] <XXCoder> you could even make one
[06:26:44] <jthornton> I wonder if you even need to bend them?
[06:26:56] <XXCoder> minium 2 bends
[06:27:16] <XXCoder> more if you want good finish edges
[06:27:41] <XXCoder> though you could make accordian covers
[06:28:06] <archivist_herron> needs the bends to interlock the lips and keep it straight
[06:28:06] <XXCoder> http://www.searspartsdirect.com/part-number/5304475241/0042/253.html?utm_source=google&utm_medium=cse&utm_term=5304475241&sid=SPDxGPROD&gclid=CjwKEAjwu72pBRC9hsn2-e34vRUSJACnSYsT9F4-xY0cTm6t_VUV84vc6dy2iwNT8slN9wKZWP5XLxoCr_Pw_wcB
[06:28:26] <XXCoder> not that exact just example
[06:28:48] <XXCoder> http://www.ebay.com/itm/like/310576756754?lpid=82&chn=ps specifically for mill
[06:29:10] <XXCoder> with sheet in front to mak chip cleaning much easier
[06:30:17] <jthornton> I have a pair of those from an AC
[06:30:44] <jthornton> those are hard to clean and stay full of chips
[06:30:54] <XXCoder> hence the sheet in front :)
[06:31:18] <XXCoder> brigeport mill I used to run had one. sure makes it easy.
[06:31:43] <jthornton> a spring roll would be nice as you could open the vise all the way
[06:33:09] <jthornton> hmm if I go over the movable jaw and fasten it to the back of the vise that might work
[06:35:25] <_methods> hehe first thing i do with every vise is rip out that shield
[06:35:35] <_methods> damn thing drives me crazy
[06:35:58] <XXCoder> what vice? kung?
[06:36:09] <_methods> kurt
[06:36:10] <XXCoder> so far all kung I see has no sheild
[06:36:15] <XXCoder> oh kurt
[06:36:22] <XXCoder> painful sounding one lol
[06:36:33] <_methods> never heard of kung
[06:36:42] <XXCoder> yeah dont exist, I meant kurt
[06:36:51] <_methods> oh lol
[06:37:20] <jthornton> yea kurt look alike
[06:37:46] <_methods> hehe
[06:38:09] <XXCoder> kurt or will kurt you :P
[06:39:30] <XXCoder> heh well night
[06:39:32] <XXCoder> 4 am lol
[06:39:50] <jthornton> 6 am here
[07:10:22] <Tom_itx> jthornton a neoprene cover wouldn't work?
[07:52:53] <jthornton> it would swell up I'd bet and get blown away when I blow the chips off the vise
[08:00:43] <JT-Shop> I think I can do it with 2 u shaped covers...
[08:18:35] <skunkworks> probably better than u2 shaped covers..
[08:19:34] <JT-Shop> what would be better than U shaped covers?
[08:38:21] <archivist> skunkworks, that joke had shades on
[08:41:05] <JT-Shop> lol I didn't catch that
[08:47:49] <alex_joni> heh
[08:48:10] <alex_joni> u2 shaped album covers?
[08:51:09] <malcom2073> So, shaped like bono's head?
[08:51:13] <malcom2073> Or his sunglasses/
[08:55:32] <archivist> it will have to have an edge on it
[08:55:45] <malcom2073> Heh
[08:59:38] <polybox_user> hi, can i set decimal value to STEP_SCALE ?
[09:00:02] <polybox_user> like 913.42 ?
[09:00:40] <JT-Shop> yea
[09:01:03] <polybox_user> okay perfect. Thanks a lot
[09:01:58] * JT-Shop waves at alex_joni
[09:04:44] * alex_joni waves back
[09:09:33] <zeeshan> zzzzzzzzz
[09:11:27] <zeeshan> JT-Shop: if you make metal bellow covers
[09:11:29] <zeeshan> do let me know! :P
[09:11:40] <zeeshan> the designs ive seen are pretty involved
[09:12:24] <mozmck> anyone know what the VCP FileChooserDialog in glade is or does? I can't find any mention of it in the docs
[09:14:29] <JT-Shop> it allows you to open or save a file depending on options
[09:15:13] <JT-Shop> http://gnipsel.com/glade/gtk10a.html
[09:15:25] <mozmck> ok, what is different about that than the standard file chooser dialog?
[09:15:33] <JT-Shop> I prefer to do it this way
http://gnipsel.com/glade/gtk10b.html
[09:15:44] <JT-Shop> that I don't know
[09:16:46] <mozmck> thanks for the links. I guess I'll have to look at the code or just use the thing and see what is different.
[09:17:09] <mutley> afternoon you lovely bunch
[09:17:29] <JT-Shop> monkey pickle time
[09:17:54] <mutley> i think i need some generic advice to help point in the right direction to identify an issue im having on my machine
[09:18:52] <mutley> trying to tune it up, setting microstepping etc, but i get this "banging" that i can feel through the machine and in particular through the leadscrews when doing circular motion
[09:19:04] <mutley> im just uploading a video,
[09:19:06] <ssi> hi
[09:19:07] <mozmck> generic? try facing north. maybe your clock is set wrong - it's morning here.
[09:20:37] <zeeshan> hi
[09:20:53] <ssi> wat is up
[09:21:15] <zeeshan> getting ready to get raped on my final exam
[09:21:21] <zeeshan> im 30 and still doing final exams
[09:21:24] <zeeshan> .. :[
[09:21:32] <ssi> lol
[09:21:38] <ssi> I didn't realize you were 30
[09:21:45] <zeeshan> gettin up there
[09:21:51] <ssi> tuesday was my birthday :P
[09:21:55] <zeeshan> happy belated :D
[09:21:58] <ssi> thx :)
[09:21:59] <ssi> 34
[09:22:38] <JT-Shop> did you get the plane?
[09:23:21] <ssi> no :(
[09:23:23] <ssi> haha
[09:23:31] <ssi> I'm waiting on my contents money, then I may buy something
[09:23:35] <ssi> should be 2-3 weeks
[09:23:41] <JT-Shop> no one would part with 100k I guess
[09:23:51] <ssi> no, nobody loves me that much
[09:25:32] <ssi> https://pbs.twimg.com/media/CCt_XW6WMAAeKdL.jpg:large
[09:25:45] <zeeshan> thats a nice pic
[09:25:50] <zeeshan> and a nice plane
[09:26:00] <ssi> :D thx
[09:26:04] <ssi> I got a shit ton done this week
[09:26:15] <ssi> https://pbs.twimg.com/media/CCt_m15WEAA47Fy.jpg:large
[09:27:58] <mutley> gahhh bloody technology
[09:28:15] <mutley> being to clever and suspending my upload
[09:28:18] <mutley> on its way now
[09:29:04] <mutley> im trying to establish suitable microstepping, an some other settings, (its not linuxcnc hence the generic questions) to point me in right direction
[09:29:17] <mutley> not after spoon feeding, but just some thought or opinion
[09:29:28] <mutley> no doubt ill get a couple of wise cracks too ;p
[09:31:37] <zeeshan> maybe you have a ton of backlash? :D
[09:37:30] <mutley> no backlash
[09:37:35] <mutley> ok heres the vid
[09:38:17] <mutley> the noise actually isnt that audible, you can just hear it in parts toward the end, its 30 second clip, but you can see the effect, by the piece of counduit over the gantry shaking
[09:38:18] <mutley> https://www.youtube.com/watch?v=31v5tujdygk
[09:39:04] <mutley> im also playing around with icrostepping settings, this sounds to be singing a little too much,
[09:39:16] <mutley> in that vid its 2560 steps per mm
[09:39:25] <mutley> which is admittedly prob too high
[09:40:00] <mutley> but im tying to snuff out this banging noise, you can feel it through the machine, and particularly on the screws, it is eminating from the motors
[09:40:33] <mutley> its almost like a missed step, and its not just during direction changes,
[09:41:34] <mutley> and i have released the motors and turned screws by hand, they are not seized or sticking
[09:41:38] <JT-Shop> mutley, did you do a stepper test?
[09:42:06] <mutley> JT-Shop: stepper test?
[09:42:17] <JT-Shop> http://www.linuxcnc.org/docs/html/common/Stepper_Diagnostics.html#_testing
[09:42:27] <JT-Shop> yea, you just don't guess at the settings
[09:42:46] <JT-Shop> usually acceleration is 10-20 times bigger as max velocity
[09:43:38] <pcw_home> sounds like a bad pulse stream
[09:43:38] <JT-Shop> as/than
[09:44:31] <mutley> JT-Shop: understood about not guessing settings, i have done an equivalent test moving the axis back and forth and checking the distant with a large digi caliper
[09:44:44] <mutley> doing 500mm moves back and forth,
[09:44:54] <mutley> travels 500mm, returns 500mm
[09:45:55] <mutley> pcw_home: interesting thought, so you can hear those noises i refer to above the whine of the steppers?
[09:48:16] <pcw_home> yes, and they happen at a ~ constant rate regardless of motor speed
[09:49:13] <mutley> pcw_home: mmm ok interesting, when you say costant rate, you mean like a drum beat constant rate, or constant rate of motion on the axis
[09:49:48] <mutley> mind you going in circular motion it wont be constant speed at all
[09:49:52] <archivist> ssi I obtained a pile of microfiche of manuals service info etc for small planes, ex skip CAA
[09:50:16] <mutley> and come to think of it, when i job the axis, the movement is fine and smooth with no banging noise
[09:50:16] <cradek> mutley: did you say it's only while doing circles?
[09:50:25] <pcw_home> constant thump rate even during circular motion suggest bad pulse stream to me
[09:50:27] <mutley> cradek: yes
[09:50:52] <pcw_home> bad gcode/interpreter?
[09:50:54] <cradek> if you put your hand on it can you tell which motor is thumping?
[09:51:08] <cradek> what software is it?
[09:51:30] <mutley> pcw_home: ok, sounds like a possibility, and what would be the cause of something like that, bad stepper wiring or more control based
[09:51:40] <mutley> cradek: can feel it on both X and Y
[09:51:57] <pcw_home> control would be my guess
[09:52:03] <mutley> cradek: its planetcnc
[09:52:41] <pcw_home> circle made from line segments and improper blending?
[09:52:43] <cradek> oh I have no idea what that is
[09:53:16] <mutley> pcw_home: that is exactly the sort of thing it feels like
[09:53:16] <cradek> http://forum.planet-cnc.com/viewtopic.php?f=6&t=1342
[09:53:39] <cradek> there are some options about arcs
[09:54:01] <cradek> but you should probably use linuxcnc instead
[09:54:05] <mutley> ill say i kind of inherited the control system that came with the machine, it was a ready runner, but im not so confident in it tbh
[09:54:23] <mutley> cradek: yea i see those,
[09:54:34] <cradek> you could scope the pulse output and see exactly what the breakage is
[09:54:40] <cradek> but surely pcw_home is right
[09:55:12] <mutley> btw guys, im kinda a bit lost in my assessment or investigation of this, so i am keen on some clear and knowledgeable thuoghts that put me onto a right track, wood for tree and al that
[09:57:16] <mutley> for a machine like that, what would you guys through experience, consider a suitable microstep rate
[09:57:24] <archivist> creaking from couplers possibly too
[09:57:51] <mutley> archivist: not couplers, its a very solid banging eminating out of the motor,
[09:57:53] <mutley> s
[09:58:16] <archivist> crap in gantry rollers/slides
[09:58:17] <mutley> pcw_home: tht does sound like the sort of thing
[09:58:32] <mutley> archivist: no ive had the motors disconnected from screws
[09:58:52] <archivist> then throw that control away
[09:59:04] <ssi> archivist: nice!
[09:59:34] <mutley> archivist: i not far off that tbh
[09:59:58] <mutley> if i had built this, not sure i would have gone with this control system
[10:00:16] <pcw_home> Ive heard of the Smooth-Stepper, maybe they should call this one "Rocky-Road"
[10:00:20] <mutley> im just looking in settings, it does seem like something to do with arc control
[10:00:31] <mutley> pcw_home: i agree
[10:01:51] <mutley> another thing ive noticed is that even if i crank up the feedrates in the gcode generator (CAMBAM) im not achieving any change in the feedrate, when generting for the same mop
[10:02:33] <archivist> ssi reading a page of one fiche had problems with cracking and cylinders falling off the continental radial
[10:03:49] <ssi> haha
[10:05:00] <archivist> it will take a "while" to catalogue and add to my online index
[10:06:26] <mutley> ha i think ive just nailed
[10:07:05] <mutley> pcw_home: you gve me the lead i needed
[10:07:46] <mutley> helix interpolation disabled
[10:07:55] <mutley> unchecked that and smooth as silk
[10:08:13] <mutley> and im reaching the feedrtes that were set
[10:08:17] <cradek> so yeah anyway, use linuxcnc
[10:08:35] <cradek> "we couldn't get this to work so we added a checkbox"
[10:08:37] <mutley> cradek: i do intend to go down that route
[10:08:53] <mutley> cradek: yea thats what i have here
[10:09:27] <mutley> helix interpolation is now active cradek, it was off
[10:09:54] <mutley> not sure i recall actually touching it either, and this has been an unnoticed problem for a little while
[10:11:05] <mutley> what would determine init and accelertion speeds on a cnc, and what would one expect for a machine like in that vid
[10:11:20] <mutley> by init, im presuing thats jerk setting,
[10:11:33] <mutley> although i guess my own jerk value is quite high atm ;p
[10:12:15] <mutley> crrently in the settings, init/jerk is set to 0 and accell is 25
[10:12:48] <mutley> assuming mms as the unit
[10:14:46] <mutley> or is that like asking how long is this piece of string
[10:15:08] <mutley> major influences would be machine rigidity and tool bits used?
[10:16:21] <mutley> and yes, i am being lazy for a quick informative idea, but will be doing more research into this
[10:16:29] <mutley> was just wondering
[10:16:42] <malcom2073> Heya mutley
[10:17:06] <mutley> heya malcom2073
[10:17:12] <mutley> how goes
[10:17:17] <malcom2073> Goes great, yourself?
[10:17:39] <malcom2073> Saw the video, new toy? Looks nifty
[10:17:43] <mutley> gahhh, this cnc machine and its gremlins (but i suspect ore a user issue;p)
[10:18:20] <mutley> nah had it a while, it just doesnt get much use, and i think an (auto) firmware update set a checkbox on something that just screwed me
[10:18:54] <malcom2073> Yowch heh
[10:18:55] <mutley> but pcw_home and cradek got me on the right path to spot it
[10:19:43] <malcom2073> Awesome
[10:20:40] <mutley> so, one last question then, got a check box here "split arcs"
[10:22:07] <cradek> so you have four possible combinations of options for "try to get arcs to work right"
[10:22:15] <cradek> we have no idea what those do
[10:22:33] <cradek> maybe you should use linuxcnc :-)
[10:22:36] <mutley> yea i guess its boils down to how the guy coded it
[10:22:46] <mutley> cradek: lol ok i get the idea
[10:23:17] <mutley> and yes i feel very aware of being that annoying noob that asks the same question in different ways and gets annoying
[10:41:57] <JT-Shop> mutley, the stepper test is to test acceleration and max velocity so you can set those at a reasonable value
[10:48:14] <mutley> JT-Shop: aha ok, thanks for the tip
[10:48:47] <mutley> im actually running a cut now and things seem to be running ok, ill have to check the dims of the finished part though to be sure
[10:58:28] <jthornton> dimensions not correct are usually related to scale not acceleration and max velocity
[11:22:18] <mutley> jthornton: or tool deflection ;)
[11:24:00] <mutley> jthornton: but yes i do agree, however i have been batting a problem with a 1mm bit, 13mm deep, giving me out of round gear profiles, part of the issue was deflection of the bit even though running it at very low feeds
[11:24:44] <mutley> but ive also just found antoher setting, path approximation was set to 0.2, and my out of round was guess what, 0.2ish
[11:25:30] <mutley> so now i do the first part of the cut with a 10mm long bit, and then the last 3mm with the 13mm deep bit but uch slower feed
[11:25:48] <mutley> the tooth profile is 13mm deep hence the need for the bith depth
[11:27:14] <JT-Shop> mutley, have you read this short chapter in the lovely manual?
http://www.linuxcnc.org/docs/html/common/User_Concepts.html
[11:27:43] <JT-Shop> yes, tool flex can not be known by the control software...
[11:28:50] <mutley> so forgive me for asking, but just to confirm, linuxcnc is control software not path generation software
[11:29:19] <archivist> mutley, you are cutting gears the wrong way to get a good form
[11:29:41] <mutley> archivist: yea i get that
[11:30:10] <mutley> its not the ideal, especially for these particular gears, but with care you can get quite a good result
[11:30:32] <mutley> archivist: although what would you suggest instead? i only have the cnc at my disposal
[11:30:52] <mutley> proper hobber machine?
[11:31:21] <archivist> proler gear cutters and a rotary controlled by the cnc
[11:31:26] <archivist> proper
[11:32:18] <mutley> archivist: got a link to an example??
[11:32:24] <archivist> hobbing being better than gear milling
[11:32:42] <mutley> id imagine this is major money though
[11:34:13] <archivist> a 4th axis is not too bad
[11:37:00] <archivist> the money is in cutters usually
http://www.archivist.info/cnc/target.php
[11:38:19] <archivist> being a crap picture but one of the few showing a form cutter and the job
[11:40:37] <mutley> archivist: ive seen cutter wheels on ebay and in tooling shops, they are not so dear
[11:40:52] <mutley> ive got a rotary table, albeit a manual one here
[11:41:05] <mutley> but i wouldnt call it a high end one either
[11:41:53] <mutley> are you suggeting to clamp the gear to the rotary, clamp rotary to bed of cnc, and ut cutting wheel into the spindle on a shaft?
[11:42:15] <mutley> or another setup, or a specific machine especially for gear cutting
[11:42:34] <mutley> the problem is, one of the gears is a one piece compound gear
[11:42:35] <archivist> cutter costs mount up when you need about 7 for one gear DP/MOD size and any number of teeth, hobbing cutters cover any number of teeth on one cutter
[11:43:10] <archivist> press fit two gears together
[11:43:28] <mutley> archivist: that is an option, im cutting them out of a PET material
[11:43:42] <mutley> one of them anyway, the other is out of nylatron
[11:44:05] <mutley> the originals are injection moulded, which might help explain a bit
[11:45:07] <archivist> you can make that type of gear from solid by shaping too (turn to od first)
[11:47:21] <mutley> yea i have thought about turning, id need to get a bigger chuck for my lathe first, or a bigger lathe
[11:47:35] <mutley> atm i mill out from 30mm thick sheet
[11:48:17] <mutley> gear stands 29mm tall, so the thick sheet/block does act as a good hold down
[12:00:15] <mutley> i am noticing a big difference in the way the waste is falling away from the gear after the change to the path deviation setting, much more even around the gear, looks promising
[12:00:28] <mutley> 1hr 20mins to do the teeth on one gear
[12:00:46] <mutley> sorry, both sets of teeth on one gear
[13:07:59] <Tecan> https://www.youtube.com/watch?v=gAdaxYVo_RU
[13:12:59] <Tecan> im wondering if a backpack would help or if the nozzle should actually be half that size
[13:20:35] <Tecan> would come in handy for restoring farm equiptment
[13:21:24] <Tecan> whats the best way to derust a hydraulic cylinder piston ?
[13:21:32] <Tecan> has some pitting too
[13:22:00] <JT-Shop> hcl?
[13:22:11] <Tecan> ya ?
[13:22:35] <Tecan> worth a shot anyway you mean a bath
[13:22:59] <Tecan> electric too ? what %
[13:23:40] <JT-Shop> yea, I dip rusty metal in HCL then when clean baking soda then in some sodium nitrite
[13:24:06] <JT-Shop> I've done the DC in washing soda before, slow but works
[13:29:15] <Tecan> back in a byte
[14:26:21] <Computer_Barf> so I got my mesa 7i76e card in the mail today
[14:26:50] <MrSunshine> kill it with fire!
[14:27:14] <Computer_Barf> well that's mean
[14:28:43] <MrSunshine> oh . i thought it was a codeword for spider
[14:28:46] <MrSunshine> carry on
[14:29:33] <MarkusBec> Computer_Barf: year kernel build actions incoming
[14:30:18] <Computer_Barf> sorry huh? I'm pretty newbish to this field
[14:34:22] <Computer_Barf> MarkusBec: can you tell me what you mean by that?
[15:53:59] <XXCoder> damn
[15:54:18] <XXCoder> the nema23 mounts works fine for motors
[15:54:46] <XXCoder> but frame uses screws to hold down bearings and those are on way
[15:54:56] <XXCoder> not sure what to do atm
[15:59:25] <SpeedEvil> High tensile duct tape?
[15:59:36] <XXCoder> lol\
[15:59:38] <XXCoder> space tape
[16:03:20] <XXCoder> http://www.octanecreative.com/ducttape/NASA/
[16:11:42] <XXCoder> SpeedEvil: would one screw be enough to hold it in?
[16:12:12] <XXCoder> maybe same screw type but with large washer or something
[16:13:25] <SpeedEvil> I have no idea
[16:14:03] <XXCoder> np
[16:14:08] <XXCoder> gonna go anyway
[16:14:32] <SpeedEvil> '
http://www.amazon.com/Claws-That-Catch-Looking-Glass/dp/1439133131 uses as a plot point 'space tape' costing $100K/30ft roll
[16:17:17] <XXCoder> SpeedEvil: yep lol
[16:17:27] <XXCoder> I recently finished that series
[16:17:30] <XXCoder> bit silly series
[16:17:37] <SpeedEvil> But good.
[16:17:55] <XXCoder> bit of annoying author tract in it but ignore that and all good
[16:27:03] <andypugh> I wonder if the next book in the series will be called “Frumious Bandersnatch”?
[16:28:30] <Computer_Barf> what is the book about??
[16:33:34] <SpeedEvil> http://www.baenebooks.com/chapters/0743498801/0743498801.htm?blurb
[16:34:55] <SpeedEvil> Basically 'action' SF - without too much deep thought, but fun.
[16:38:54] <malcom2073> I like it
[16:39:03] <malcom2073> I'ma have to put that on my list
[16:39:59] <Deejay> gn8
[16:45:55] <malcom2073> HAha oh boy, it's a higgs bosun particle armageddon book
[16:45:56] <malcom2073> awesome
[16:46:06] <malcom2073> I'm definently gonna pick this one up
[16:55:59] <Computer_Barf> "note: 5vp pins are PTC short circuit protected 5v output pins for field wiring."
[16:56:10] <Computer_Barf> field wiring?
[16:56:40] <Computer_Barf> is all that a fancy way of saying that , here are some spare 5v / gnd pins in case you need it
[16:58:04] <PCW> it saying that if you power it with your 25A 5V PC supply it will not burn up your wires in the event of a short
[16:59:46] <Computer_Barf> well the note was concerning some gnd and 5v line that are next to the +/- dir and pull
[17:00:38] <PCW> some step drives have common anode OPTOs (so you need +5V)
[17:00:52] <Computer_Barf> im trying to hook up my mesa 7176E here
[17:01:08] <Computer_Barf> ahh that makes sense. I figured it was just an extra supply for situations where you might need it
[17:01:11] <PCW> so have common cathode OPTOs (so you need ground)
[17:01:50] <Computer_Barf> my driver has ena+ ena- but i had read on hoss's site that those are left unused
[17:02:03] <PCW> some have independent OPTOs so you can drive them differentially for better noise immunity
[17:02:45] <PCW> yeah those are really +DISABLE and -DISABLE
[17:02:57] <PCW> a bad idea
[17:03:50] <PCW> you should have to supply a signal to enable a drive (so a broken connection disables the drive)
[19:23:44] <zeeshan> http://gyazo.com/dbddb0f9baaa57d0cca8f06d2fcf5f03
[19:23:47] <zeeshan> about to machine this handle for someone
[19:23:52] <zeeshan> its got a tapped hole in the end
[19:24:01] <zeeshan> im thinking of making it a 2 step process, drill and tap the hole
[19:24:11] <zeeshan> then machine the contour
[19:24:16] <zeeshan> cause i wont be able to hold it after
[19:24:20] <zeeshan> unless i make a soft jaw for the lathe
[19:24:23] <zeeshan> which i dont want to :P
[19:24:38] <norias> sounds right to me
[19:24:55] <zeeshan> since i gotta make like 10 of them
[19:25:05] <zeeshan> think it might be easier to just drill and tap on the mill? :D
[19:25:13] <norias> hmm, no
[19:25:18] <norias> not in my opinion
[19:25:27] <zeeshan> cause ill have to manually tap for the lathe =/
[19:25:29] <zeeshan> *in
[19:25:31] <norias> eh.
[19:25:35] <norias> but it's ten parts
[19:26:38] * zeeshan lazy
[19:26:56] <zeeshan> i really wish just about now that i had a morse taper attachment
[19:26:56] <norias> lol
[19:27:00] <zeeshan> for the quick change tool post
[19:35:03] <zeeshan> if i have a font
[19:35:09] <zeeshan> is there a program out there that can convert it to g-code
[19:35:15] <zeeshan> for engraving
[19:38:09] <norias> uh, hmm
[19:38:14] <norias> good question.
[19:41:08] <norias> blah @ CNC controllers
[19:41:13] <norias> and their stupid interfaces.
[19:47:57] <zeeshan> haha
[19:58:48] <norias> trying to figure out how to make web sites these days
[19:58:52] <norias> last time i did it
[19:58:59] <norias> it was all about the Perl
