07:07 AM Tom_L: morning
07:10 AM jthornton: morning
07:34 AM elmo40: moo
07:55 AM pink_vampire: hi
07:59 AM jthornton: hi
08:07 AM pink_vampire: https://imgur.com/a/Cfn7NFa
08:30 AM jthornton: nice
09:03 AM pink_vampire: thanks
11:01 AM pink_vampire: i need metric drill set
11:06 AM pfred1: I need a metric conversion program
11:06 AM pfred1: I got metric drills
11:07 AM pink_vampire: send me 8mm and 3mm drills
11:07 AM pfred1: get them off aliexpress
11:07 AM pfred1: unless you're drilling something hardened they're generally good enough
11:08 AM pink_vampire: i need them for brass
11:08 AM pfred1: then brass them off
11:08 AM Tom_L: https://www.ebay.com/bhp/metric-drill-bit-set
11:08 AM pfred1: driulling brass with bits that aren't brassed sucks big time
11:09 AM Tom_L: kinda sucks a little anyway
11:09 AM pfred1: you just take a stone and dull the edge
11:09 AM pfred1: like one touch makes a world of difference
11:09 AM Tom_L: i know the trick
11:10 AM pfred1: I remember driling brass on my mill without a brassed bit I was like wholly this sucks
11:10 AM Tom_L: but usually don't do it on my home set since it's multi use
11:10 AM pfred1: I was also thinking isn't brass supposed to be nice to machine?
11:11 AM pfred1: folks must just have a lot of dull tools
11:11 AM Tom_L: likes to grab
11:11 AM pfred1: it sure does
11:11 AM pfred1: grab and self feed
11:11 AM Tom_L: kinda the opposite of ss
11:12 AM pfred1: I hate all the weirdo materials
11:12 AM pfred1: mild steel or bust
11:13 AM pfred1: I remember trying to tap some stainless once i was like this is impossible
11:13 AM pfred1: I busted so many taps doing it
11:13 AM Tom_L: proper lube helps
11:14 AM pfred1: I finally drilled it way up so there was just barely a shadow of a thread
11:14 AM Tom_L: we used stuff we called 'tap honey'
11:14 AM pfred1: and that worked
11:14 AM pfred1: it was a tiny tap like 8-32?
11:14 AM pfred1: which usually is no problem
11:15 AM pfred1: but even with barely no threads it still held
11:15 AM pfred1: I learned my lesson that day go big
11:15 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/reprap/drive6.jpg
11:15 AM Tom_L: left one is ss i rolled with a 3mm tap
11:39 AM roycroft: i'm still dealing with the broken tap from hell
11:39 AM pink_vampire: http://www.tolsentools.com/
11:39 AM roycroft: i've spent hours trying to get it out
11:39 AM roycroft: it's a 6-32, so small, but not tiny
11:40 AM roycroft: i just ordered some 7/32" carbide end mills - hopefully i'll be able to cut through it with those
11:41 AM roycroft: i don't even know how i broke it - usually it's 4-40 taps that i break
11:41 AM roycroft: but the steel felt more like that crap they use to make bed frames - melted down cars with varying hardness throughout
11:42 AM roycroft: so maybe i can blame it on the metal
11:44 AM pfred1: yeah hard inclusions
11:45 AM pfred1: I got some old USS I salvaged off jobs so buttery soft and smooth
11:47 AM roycroft: this broken tap is in my belt grinder that i'm building
11:47 AM roycroft: i can't finish painting it until i deal with the tap
11:47 AM roycroft: but i went to the steel yard yesterday and bought some tubing and plate to make the stand for the belt grinder
11:47 AM roycroft: i can fab that while i'm waiting for the end mills
11:48 AM roycroft: and since steel is going way up in price any day now, it's good that i bought that stuff when i did
11:48 AM pfred1: when I worked in a machine shop we'd make punches out of beat reamers to bust broken taps out with
11:48 AM roycroft: so maybe the broken tap from hell is going to be a benefit
11:49 AM pfred1: just put a point on them and start hammering
11:49 AM roycroft: i've tried using carbide and diamond burrs
11:49 AM pfred1: we'd just shatter the taps out
11:49 AM pfred1: taps break up like glass when hit
11:49 AM pfred1: or they should
11:49 AM roycroft: but i did not have any small enough, and we have no good tooling suppliers around here, so i got them at harbor freight
11:49 AM roycroft: they would last for seconds at most
11:49 AM roycroft: i beat the crap out of this tap
11:49 AM pfred1: harbor freight tap?
11:50 AM roycroft: no, harbor freight carbide burrs
11:50 AM pfred1: ah
11:50 AM roycroft: if it were a harbor freight tap i'd be able to stare it out :)
11:50 AM pfred1: I was gonna say harbor freight tap probably pretty tough stuff not so glass hard
11:50 AM roycroft: i tried heating it up with a torch
11:50 AM roycroft: but i could not punch it out
11:51 AM roycroft: and that did not anneal the tap
11:51 AM pfred1: probably not
11:51 AM roycroft: i think it just welded it into the hole
11:51 AM roycroft: and made things worse
11:51 AM roycroft: hopefully the end mills will work
11:51 AM pfred1: yeah I've drilled stuff up tapped it plugged it and welded it
11:51 AM roycroft: if the end mills don't work i'll just give up
11:52 AM pfred1: like if I'm using some scrap metal and there's a hole in it in a bad place
11:52 AM roycroft: i don't really need that hole - it's just for mounting a shroud over the motor to help keep the dust out
11:52 AM roycroft: not structural at all
11:52 AM roycroft: and there are several other screws to hold the shroud in place
11:52 AM pfred1: yeah I'd probably let it go if it isn't critical
11:52 AM roycroft: but it's very visible
11:52 AM roycroft: it would look funny if it were missing
11:52 AM pfred1: get some JB Weld it
11:53 AM roycroft: but i can always cut the thread off the fastener and jb weld the head in place
11:53 AM pfred1: there you go
11:53 AM roycroft: i hate doing hacks like that
11:53 AM pfred1: yeah well
11:53 AM roycroft: but i'm not going to remake the part - i welded it up really well and it would be a major pain in the butt to cut it out and replace it
11:53 AM pfred1: the physical universe often works at odds to us
11:54 AM roycroft: anyway, i have a few days before the end mills arrive, so i'll work on the stand
11:54 AM roycroft: which will be good, because without that stand the only way i can use the grinder is in the vertical position - the bench to which i had it temporarily mounted will not allow me to swing it horizontal
11:54 AM roycroft: so i know i'll want a proper stand as soon as the grinder is painted
11:55 AM pfred1: I've had good luck welding up tapped plugs
11:55 AM pfred1: that's what I love about steel always the option to weld it
11:55 AM roycroft: the bad thing is that i need the grinder to fabricate the stand, so now i have to reassemble it, make the stand, disassemble it, finish painting it, then reassemble it again
11:55 AM roycroft: the tap is broken off well beneath the surface on both sides
11:55 AM roycroft: i would have welded something to it if i could get in to do that
11:56 AM roycroft: i've done that before with success
11:56 AM pfred1: yup
11:56 AM roycroft: this is the first tap i've ever not been able to get out
11:56 AM pfred1: it happens
11:56 AM roycroft: and i've had to remove quite a few broken taps over the decades
11:56 AM roycroft: yeah
11:57 AM roycroft: i was tapping some 1/2-11 holes in the same material yesterday, and it got pretty crunchy a few times
11:57 AM pfred1: that's a weird size
11:57 AM roycroft: i've never broken a tap that big, but i was afraid it was going to happen yesterday
11:57 AM roycroft: er, 1/2-13
11:57 AM roycroft: sorry
11:57 AM pfred1: my CNC machine uses 1/2x1- TPI acme
11:57 AM roycroft: it was orignally supposed to be 5/8-11
11:57 AM pfred1: whoops 1/2x10
11:57 AM roycroft: but the wrong parts came in
11:58 AM pfred1: yeah 1/2x13 is UNC
11:58 AM roycroft: fortunately they arrived right before i drilled and tapped the holes
11:58 AM roycroft: leveling feet they are
11:58 AM roycroft: and i was making the mounting pads that i weld to the bottom of the legs
11:58 AM roycroft: i was thinking 5/8-11 when i said 1/2-11
11:58 AM pfred1: once on a job I got a whole box of 1/2x13 UNC threaded rod someone threw out so it is popular here
11:59 AM roycroft: it looks like it might rain today
11:59 AM roycroft: and all that tubing and plate is still on the back of my pickup
11:59 AM pfred1: it's been raining here all day
11:59 AM roycroft: i should probably go clean it up and stash it in the welding shop
11:59 AM pfred1: I need cattle to graze on my lawn
11:59 AM roycroft: it was supposed to be sunny and hot through mid-week
11:59 AM roycroft: but the storm is arriving early
12:00 PM pfred1: when it dries I'll be mowing it then
12:00 PM roycroft: frankly i'm happy about this
12:00 PM roycroft: i like warm, sunny weather
12:00 PM roycroft: but it's been really hot for a week
12:00 PM roycroft: this is early may - i'm not ready for a summer heat wave yet
12:00 PM pfred1: not me the sun and I never see eye to eye
12:00 PM roycroft: and we have three fires in my county and the county just to the south
12:00 PM roycroft: fire season does not begin officially until next month
12:01 PM pfred1: you couldn't start a fire in my woods to save your life right now
12:01 PM roycroft: and we just finished cleaning up from an historic snowfall
12:01 PM roycroft: now there are wildfires
12:01 PM roycroft: it's crazy
12:01 PM pfred1: I didn't have to shovel my driveway once this year it was great
12:02 PM roycroft: i still have 3-4 pickup loads of downed limbs from the snow storm to haul away
12:02 PM pfred1: I just toss all of my brush in my woods
12:02 PM pfred1: you wouldn't believe how fast it rots
12:03 PM roycroft: if i had some woods i might do that
12:03 PM pfred1: the woods has a way of dealing with dead wood
12:03 PM roycroft: it gets too hot and dry here in the summer for that to happen
12:03 PM pfred1: I'm 2/3rds wooded on my lot
12:03 PM roycroft: nice
12:03 PM pfred1: ah it is and it isn't
12:04 PM pfred1: there's definitely a downside to living in the sticks
12:04 PM roycroft: as long as the 1/3 is big enough for you do what you need to do
12:04 PM roycroft: ideally i'd like some property just outside city limits instead of just inside city limits
12:04 PM pfred1: once i had a dead tree hanging over my tractor shed
12:04 PM roycroft: the best of both worlds
12:04 PM pfred1: it was fallen but stil held up by vines
12:04 PM pfred1: that was a sketchy day
12:05 PM roycroft: yeah, i can imagine
12:05 PM pfred1: I ended up getting on the roof of the shed and chainsawing it and then it still stayed up
12:05 PM pfred1: then i was like now what am I going to do?
12:05 PM pfred1: this tree was over a foot in diameter too
12:05 PM roycroft: ropes/chains and a tractor to pull the pieces away
12:05 PM pfred1: I just got a little lawn tractor
12:05 PM roycroft: all the while hoping nothing goes wrong
12:06 PM pfred1: I fo have come alongs and chainhoists and that kind of stuff
12:06 PM roycroft: a block and tackle turns that little lawn tractor into a big farm tractor :)
12:06 PM pfred1: I just kept chainsawing it up into pieces and I got it down
12:07 PM pfred1: them vines had more of a grip on it than I'd imagined they did
12:07 PM roycroft: i have an aspen tree, fortunately pretty small, that is leaning onto the fence between my property and my neighbor's
12:07 PM roycroft: the roots are coming out of the ground - the snow storm uprooted it
12:07 PM pfred1: one thing I don't have is neighbors
12:07 PM roycroft: the neighbor won't let me on her property to cut it down there
12:07 PM pfred1: yeah I just love cooperative people
12:07 PM roycroft: so i have to figure out a way to cut it down while pulling it back onto my property
12:08 PM roycroft: and it's leaning at about a 45 degree angle, so it's going to be a very tough pull
12:08 PM pfred1: or don't do anything and when something happens it is an act of God
12:08 PM roycroft: it's my fence
12:08 PM pfred1: you're still covered
12:08 PM roycroft: so when it falls, i can cut it at the property line, remove my part, and she can't do anything about the part on her property
12:08 PM _unreal_: any suggestions for a touch plate and touch probe from ali...
12:08 PM roycroft: but i'll still have to repair the fence
12:08 PM pfred1: it's when yo udo something that you're liable
12:08 PM roycroft: i'd like to remove it before that happens
12:09 PM roycroft: it's small enough that i think if i can sling a rope over it far enough on her side and pull back, i can probably pull it almost upright before i would have to do any cutting
12:09 PM pfred1: I have trees here i need to drop but doing it would be sketchy
12:10 PM roycroft: i'm not going to hire a tree removal outfit to do this job, although i know they would be able to just pick it up and haul it away
12:10 PM roycroft: that would cost more than repairing the fence
12:11 PM roycroft: so i may end up just letting it go until it falls over completely
12:11 PM pfred1: yup any tree work you're looking at like a grand
12:11 PM pfred1: but I've almost killed myself with some of the stunts I've pulled too
12:11 PM roycroft: plus permitting
12:11 PM roycroft: we have restrictions on tree cutting
12:11 PM pfred1: I was cutting a branch out of a tree in the front yard and i almost knocked myself off the ladder
12:12 PM roycroft: and while this one is easily small enough to be ok to cut
12:12 PM roycroft: not to mention it's an aspen, which is more a big weed than a tree
12:12 PM pfred1: here if we want t oclear cut our property it's all good
12:12 PM roycroft: the city will still have to come look at it and sign off on it first if i hire a tree cutting outfit
12:12 PM roycroft: and that costs money
12:12 PM pfred1: your tax dollars at work
12:12 PM roycroft: anyway, the clounds are looking more ominous
12:12 PM roycroft: so i think i'll head out and move that metal before it rains
12:13 PM pfred1: k
12:22 PM _unreal_: looking for a cheap touch probe like this https://tormach-inc.imgix.net/wp-content/uploads/sites/8/2018/04/27173910/32310_PassiveProbe_lrg.jpg?w=200
12:23 PM pink_vampire: _unreal_: make one
12:23 PM _unreal_: my cnc machine isnt working yet
12:24 PM _unreal_: I burned one of my motor controllers :(
12:24 PM pink_vampire: so... why you need a probe in those conditions?
12:25 PM _unreal_: I just ordering parts
12:25 PM pink_vampire: https://i.imgur.com/rJjl8BG.png my old trusty probe
12:25 PM _unreal_: huba huba
12:25 PM _unreal_: diy?
12:26 PM pink_vampire: yeah
12:26 PM pink_vampire: https://i.imgur.com/Q73eAKv.png
12:26 PM _unreal_: oh I made a discovery
12:26 PM _unreal_: pink_vampire, do you get on cnc zone at all?
12:27 PM _unreal_: cnczone.com
12:27 PM pink_vampire: yes
12:27 PM _unreal_: https://www.cnczone.com/forums/open-source-controller-boards/326078-cnc.html#post1984706
12:28 PM pink_vampire: ??
12:28 PM _unreal_: do you remember the website www.pminmo.com
12:28 PM _unreal_: ?
12:28 PM pink_vampire: no
12:29 PM _unreal_: https://web.archive.org/web/20120713131835/http://pminmo.com/
12:29 PM _unreal_: he's all over cnczone.com
12:30 PM pink_vampire: ok
12:31 PM _unreal_: apparently he pass away in 2017
12:31 PM _unreal_: passed
01:17 PM miss0r: pink_vampire: Should you also find this sort of stuf funny? I've rebuild this engine: https://imgur.com/a/IbK97uR
01:55 PM pink_vampire: miss0r: why funny? I think it is awesome
03:30 PM en1gma: here is my new video if anyone wants to watch it. i do a little bit of talking and if you want to help me please do https://www.youtube.com/watch?v=JvYfr9J9zew
04:11 PM Roguish: pcw_home: pcw_mesa: Peter. quick question please. 7i40 (dual drive) I have a fault on axis 1. my compressor failed and the huge knee dropped back driving the motor. RED led is stuck on, even after depower/repower. Did it kill the whole board or just the one side?
04:20 PM en1gma: can someone help me on that code? i just want it to repeat after the Y Axis moves up 1000*20 then start drop down and go back to where it started and do it all over again
04:20 PM en1gma: its probably like 2 lines of code that needs altered but im a real noob
04:21 PM en1gma: i have researched and there are lots of different ways to program these steppers with arduinos and drv8825 and nema 17. its like there was different softwares throughout the years
04:21 PM jthornton: thats not even g code...
04:21 PM pcw_home: Roguish probably just one side
04:22 PM en1gma: im also using cnc shield and everything is working perfect in that code i linked to at the pastebin link. just would be great if someone can alter it and repost it doing what i like it to do as far as repeating after it reaches 20 * 1000 in the y axis
04:22 PM Deejay: gn8
04:22 PM jthornton: goodnight
04:22 PM en1gma: i know im not sure what i should be going. should i have the arduino upload grblfirmwareupload and then do commands through serial console?
04:22 PM en1gma: what kind of code am i actually even doing?
04:23 PM en1gma: is it C with modules for steppers?
04:23 PM pcw_home: Probably repairable
05:50 PM XXCoder: pink_vampire: is tat jaws plastic or metal
06:17 PM pink_vampire: XXCoder: what jaws??
07:01 PM Jymm: woof?
07:17 PM _unreal_: pink_vampire, do you have the gcode for that probe?
07:22 PM _unreal_: any one ever purchased liner rails from aliexpress?
07:28 PM jdh: lmb2008
07:29 PM jdh: on ebay. billion ali sellers
07:33 PM _unreal_: ?
07:33 PM pink_vampire: _unreal_: you can use G38
07:33 PM pink_vampire: https://imgur.com/a/nBQgbHQ
07:34 PM pink_vampire: one more part is done
07:34 PM _unreal_: pink_vampire, the touch probe you built it?
07:35 PM pink_vampire: _unreal_: look at the album i just linked, you can see some probing that i did
07:35 PM pink_vampire: and yes,
07:35 PM _unreal_: do you have a GCODE for building that probe?
07:35 PM pink_vampire: I build it myself
07:35 PM _unreal_: or did you whip it out on a lathe
07:36 PM pink_vampire: no, it was one of my first projects,long time ago before I had a lathe
07:37 PM _unreal_: :)
07:37 PM _unreal_: nice
07:37 PM pink_vampire: it is just bunch of acrylic rings with some bolts
07:37 PM pink_vampire: the shaft is press fit
07:38 PM pink_vampire: there is 3 set screws on the top that allow you to flex the acrylic abit to calibrate it
07:39 PM _unreal_: I just spent the last 5 hours next door helping my elderly neighbors fixing a wiring issue to there light fixture in an ceiling fan..
07:39 PM pink_vampire: on the bottom there is a place the is recessed abit to fit a pcb with 6 ball bearings
07:39 PM pink_vampire: I'm sure you can make it
07:39 PM _unreal_: 3 sets of 2 I take it
07:40 PM pink_vampire: correct
07:40 PM Tom_L: _unreal_ i got mine on ebay
07:40 PM pink_vampire: _unreal_: https://i.imgur.com/2Y8WQQ5.png
07:41 PM _unreal_: Tom_L, pink_vampire I'm not 100% sure what I'm looking at other then a sensor of some kind?
07:41 PM _unreal_: Tom_L, got any links
07:41 PM _unreal_: I'll ether build or buy
07:41 PM pink_vampire: it is a tool setter + datum

07:43 PM Tom_L: rails & ballscrews
07:43 PM pink_vampire: Tom_L: those look like fake hiwin
07:44 PM _unreal_: Tom_L, I'm not looking for rails I'm loking for a touch probe
07:44 PM _unreal_: for 3d input
07:44 PM Tom_L: <_unreal_> any one ever purchased liner rails from aliexpress?
07:45 PM jdh: move along.
07:48 PM _unreal_: I'll build one or I'll ARG... almost 9
07:48 PM _unreal_: got to make din
07:52 PM norias: the development notes on the wiki seem... old...
07:56 PM _unreal_: ok din is now on the stove
07:56 PM _unreal_: wow 5in
07:56 PM _unreal_: 5min
08:38 PM XXCoder: pink_vampire: one you linked to
08:39 PM pink_vampire: yeah maybe
08:39 PM XXCoder: it looked like it. its pretty nice but too tall for my cnc machine lol
08:39 PM pink_vampire: did you saw this album? https://imgur.com/a/nBQgbHQ
08:40 PM XXCoder: loooking
08:40 PM XXCoder: very nice!
08:40 PM XXCoder: initially i wondered why you was making it out of alum but was wrong lol
08:42 PM pink_vampire: it is just make it very easy to combine alot of pictures
08:51 PM norias: pink_vampire: the album link didn't work for me
08:51 PM pink_vampire: mmm
08:51 PM pink_vampire: lets see
08:52 PM pink_vampire: norias: https://imgur.com/a/nB07GFw
08:53 PM norias: that's better
08:53 PM pink_vampire: I thing I removed it by mistake
08:53 PM pink_vampire: so I re-upload it
08:53 PM norias: well done
08:53 PM pink_vampire: think*
08:54 PM pink_vampire: thanks!
08:54 PM norias: i start a new job tomorrow
08:54 PM norias: as a prototype machinist
08:54 PM norias: heh
08:54 PM norias: they have a tormach
08:54 PM norias: this should be interesting
08:54 PM XXCoder: ohh
08:54 PM pink_vampire: what kind of job?
08:54 PM XXCoder: harder job than mine
08:54 PM norias: i might do some kind of instagram thing
08:54 PM XXCoder: norias is supposely must be able to make part from design, make program, make parts, etc
08:55 PM norias: "Professional machinist attempts to run a Tormach in to the dirt."
08:55 PM pink_vampire: hope for you is the better tormach
08:55 PM norias: you know...
08:55 PM norias: i'm really curious to see what i get out of it
08:56 PM norias: i'm not excited about the tooling system
08:56 PM norias: but, so be it
08:57 PM norias: i'll try a few strategies out.
08:57 PM norias: i dig the challenge
08:57 PM pink_vampire: get a tool setter and a probe, the r8 idea is... mmm
08:57 PM norias: they have the tormach tool system on this
08:57 PM norias: which i'm not excited about... but...
08:58 PM norias: it does allow me to have fixed tool lengths
08:58 PM norias: therfore i can do the poor man's tap test
08:58 PM XXCoder: tormach has toolchanger that uses toolholders?
08:58 PM norias: yeah
08:58 PM XXCoder: not bad
08:58 PM pink_vampire: I have R8 + collets
08:58 PM norias: they made their own system
08:58 PM norias: it's kinda clunky looking
08:58 PM XXCoder: does it change tool itself or you do it?
08:59 PM norias: depends on how much you spend
08:59 PM norias: this one has the automatic tool changer
08:59 PM XXCoder: not bad
08:59 PM norias: i _think_ it has a touch probe, too
08:59 PM pink_vampire: XXCoder: the TTS is just 3/4" r8 collet with flat face
09:00 PM norias: yeah, and the tool holders just have 3/4" shank
09:00 PM norias: so they index length of the spindle face
09:00 PM XXCoder: well from what you discribe it can do many jobs
09:00 PM norias: i was poking at some numbers
09:00 PM XXCoder: not ones that uses large tools
09:00 PM pink_vampire: on the tools there is a ring that you *hope* will touch flat on the face of the spindle
09:00 PM XXCoder: nor HUGE
09:00 PM norias: and cat30 taper is damn near the same as the taper part on r-8
09:01 PM norias: to the point that some people report actually having put cat30 tooling in to an r-8 spindle
09:01 PM pink_vampire: not iso 30?
09:01 PM norias: oh, yeah iso 30
09:01 PM norias: maybe. it was late.
09:01 PM XXCoder: not bad. cat30 is cheap
09:01 PM XXCoder: just need compitable pull tabs
09:01 PM norias: so, there's a thought
09:01 PM norias: yeah, which is non-trivial, but still
09:02 PM norias: in theory you could make a thing that replaces the drawbar in r-8
09:02 PM norias: some kind of actuator plus some disc springs
09:02 PM norias: and a gripper, as you mentioned
09:02 PM norias: i'm really surprised that's not a kit somewhere
09:03 PM norias: i'm gonna buy a cat-30 tool and see if i can do something like that
09:03 PM norias: because why not
09:03 PM XXCoder: yeah
09:03 PM pink_vampire: you think the r8 taper is the same as iso30??
09:03 PM XXCoder: compare r-8 pull tab and see
09:03 PM norias: pink_vampire: look them up
09:03 PM XXCoder: see if you can make tabs
09:04 PM norias: i think it's feasible.
09:04 PM XXCoder: i finally saw cnc machine doosan's pull spring and bar. interesting
09:04 PM norias: good idea? dunno
09:04 PM norias: will it work well? dunno
09:04 PM XXCoder: it was dying so it made my job very very hard
09:04 PM norias: but given that my goal is to design and build a tormach sized machine, eventually
09:04 PM norias: it's worth playing around
09:05 PM norias: although, i want an hsk spindle
09:05 PM XXCoder: whats your work volume requirements?
09:05 PM norias: good question. haven't started the job yet
09:05 PM XXCoder: ok. good idea to work for a bit see what kinda parts you deal with
09:05 PM norias: realistically, we talked about budgetting for a "real" cnc
09:06 PM norias: so, i'm just going to run the tormach for all it's worth until then
09:06 PM XXCoder: haas can be quite cheap but also has limitions
09:06 PM norias: yeah, i've run a bunch of haas machines
09:06 PM XXCoder: rpm is like 6k max on one i ran at work. very cheap machine
09:06 PM XXCoder: compare with robodrill which can go to 20k rpm
09:06 PM norias: you can do a lot with 6k, though
09:06 PM norias: especially if you have the feeds
09:07 PM XXCoder: btw robodrill is VERY good. try to have temperate control in room its in though!
09:07 PM pink_vampire: http://www.tools-n-gizmos.com/specs/Tapers.html
09:07 PM norias: yeah
09:07 PM norias: i've built shops, before
09:07 PM norias: which is why they hired me
09:07 PM XXCoder: nice
09:07 PM pink_vampire: what is 7/24 taper??
09:07 PM norias: because they plan on scaling up, moving to a new location
09:07 PM norias: which means building a new shop
09:08 PM XXCoder: i menioned temperate for robodrill because i ran em in shop with zero temperate control besides keeping it at 70f or higher
09:08 PM norias: i've actually been in management the past two job, but i'm stepping down a bit
09:08 PM pink_vampire: 8.2971 degrees
09:08 PM norias: just because
09:08 PM XXCoder: so it can change .003" from "cold" to warm
09:08 PM norias: yeah
09:08 PM XXCoder: my work supervisor stepped down to machinist he got tired with dealing with shit apparently
09:08 PM norias: i did some surface grinding to 50 millionths for a bit
09:09 PM norias: you had to let the parts cool over night
09:09 PM XXCoder: dang
09:09 PM XXCoder: you're roberto? ;)
09:09 PM norias: basically, i was working 60 hours in management
09:09 PM norias: and i have a toddler
09:09 PM norias: and i just want to work 50 hours and go home
09:09 PM norias: more family time
09:09 PM XXCoder: 50 hours is more than i usually do
09:09 PM norias: i was working every single saturday
09:09 PM norias: it was stupid
09:09 PM XXCoder: 40 hours to 48 hours if i get ot
09:10 PM norias: i was the production supervisor
09:10 PM pink_vampire: cat30 8.2971 r8 8.425
09:10 PM norias: it was just stupid
09:10 PM XXCoder: too much hours your health gets shot
09:10 PM norias: yeah, and my health isn't great to start
09:11 PM XXCoder: your legs gets hurt and you need knee replacement
09:11 PM XXCoder: my lead just had one and hes younger than me. im 43.
09:11 PM norias: i have had arthritis since i was 25
09:11 PM norias: and i'm 39 now
09:11 PM norias: i have a toddler
09:11 PM norias: and a house i'm remodelling
09:11 PM norias: these guys offered me the same money for less bullshit
09:12 PM norias: and no saturdays
09:12 PM XXCoder: my back lol im cheating by sitting a lot after first shift leaves (but keeping speed of production up!) because my back cant do standing
09:12 PM XXCoder: wow nice
09:12 PM XXCoder: same pay, less hours and family more hours
09:12 PM norias: right
09:12 PM norias: so, sure
09:12 PM norias: whatever
09:12 PM norias: i'll run your tormach till it cries
09:12 PM XXCoder: lol
09:12 PM norias: when i do feeds and speeds
09:13 PM norias: i start at available horsepower
09:13 PM norias: and work backwards
09:13 PM XXCoder: so prototyping cnc production. it does mean you make your own programs, etc right?
09:13 PM norias: yeah
09:13 PM XXCoder: me, im production cnc machinist lol
09:13 PM norias: i've done that
09:13 PM XXCoder: not wow good but good enough
09:13 PM pink_vampire: sounds like my day here
09:13 PM XXCoder: pink you ARE basically a protoying machinist.
09:13 PM XXCoder: youre far mroe skilled than I am.
09:14 PM pink_vampire: I need a job
09:15 PM norias: XXCoder: dude. i've done little aluminum parts that you could get 10 in your hand
09:15 PM norias: up to castings that weigh 40 tons
09:15 PM pink_vampire: XXCoder: yeah, I love prototyping and make unique stuff
09:16 PM norias: i have photos of one of my coworkers sitting on a lawn chair on the milling machine table beside the part
09:16 PM norias: as it's being machined
09:16 PM norias: the table was like 30' x 45'
09:16 PM XXCoder: lol largest im done is what I call "bone" which is 2 feet long and half. not big enough to be 40 tons :)
09:16 PM XXCoder: dang
09:16 PM norias: crazy shit
09:16 PM pink_vampire: sounds like that
09:17 PM norias: 24" face mill
09:17 PM norias: just hogging away
09:17 PM XXCoder: i have done some various insanity parts though. like "washer" its simple, but i made 660 in 10 hours
09:17 PM norias: i think that machine was like 120 HP
09:17 PM XXCoder: i tried to make it to 666 for lols but failed.
09:17 PM norias: i know the lathes were 95-120 HP
09:17 PM XXCoder: note, ONE a time.
09:18 PM XXCoder: my current record is 750 parts in 10 hours, but it was 10 part a run
09:18 PM XXCoder: so 75 cycles. 660 is 660 cycles.
09:18 PM norias: keep at it man
09:18 PM norias: machining has it's ups and downs, but it's treated me well
09:18 PM XXCoder: other end, 2 parts. LOL
09:18 PM norias: my wife has a masters degree
09:18 PM norias: and we were making the same money
09:18 PM XXCoder: actually, ZERO parts is other end, as i couldnt count parts
09:18 PM norias: well, she made like 10k more
09:19 PM norias: but then she , one day, realized...
09:19 PM norias: i don't pay student loans
09:19 PM pink_vampire: I try not to run stuff crazy fast here, I'm doing it for fun and there is no reason to push the tools and the machine so hard
09:19 PM XXCoder: i do, sadly. for 2 degrees not related to machjnist
09:19 PM norias: yeah
09:19 PM XXCoder: i have BS on computer science
09:20 PM norias: do you code on linuxcnc at all?
09:20 PM XXCoder: nah i made 3axis-tutorial though
09:20 PM norias: you should
09:20 PM XXCoder: on older 2.7, rolfmill
09:20 PM norias: i think there's some cool stuff that can be done
09:20 PM norias: i'm trying to get up to speed so i can do some experiments
09:20 PM XXCoder: those are vismach fun to make machine.
09:21 PM XXCoder: i kinda want to extend vismach so it can get input of STOCK size from linuxcnc
09:21 PM XXCoder: problem is i have forgotten much of programming.
09:21 PM norias: eh.
09:21 PM norias: you can pick it up again
09:21 PM XXCoder: yeah other problem is i have zero willpower
09:21 PM norias: i have a book on cnc controller design
09:22 PM XXCoder: took me 2 months just to finally work on rolfmill
09:22 PM norias: so, i want to go in an change out some of the path planning in linuxcnc
09:22 PM norias: based on stuff in the book
09:22 PM XXCoder: cool :)
09:22 PM norias: see how it works
09:22 PM norias: i have some ideas to just play with
09:22 PM norias: i read some stuff i didn't fully understand
09:22 PM norias: about alternatives to PID controllers
09:23 PM norias: some lab stuff people did
09:23 PM norias: that i want to try to replicate
09:23 PM norias: too much to do
09:24 PM norias: i really, really want to build a machine
09:24 PM norias: from the ground up
09:24 PM XXCoder: its good experence
09:24 PM roycroft: i got all the frame parts for my belt grinder stand cut today
09:24 PM norias: re-think alot of stuff
09:24 PM norias: experiment
09:24 PM pink_vampire: stuff start to take shape here https://i.imgur.com/8JjtBHg.png
09:24 PM roycroft: it went really well, so i decided to start grinding the bevels on the ends of the parts, to prepare for welding
09:24 PM XXCoder: i bought a cnc frame and built cnc machine so not quite "ground up" like my orginial plan was but its good
09:25 PM roycroft: with my old belt grinder that would have taken me 5 hours or so
09:25 PM norias: XXCoder: what kind of motors?
09:25 PM roycroft: longer than the cutting out
09:25 PM XXCoder: cheap nema23s lol
09:25 PM roycroft: i got the whole job done in 45 minutes with my new grinder ;)
09:25 PM norias: I was thinking of starting with cast iron stock
09:25 PM XXCoder: spindle is pure chineseium
09:25 PM norias: to do the frame
09:25 PM norias: but then i think....
09:25 PM roycroft: granite, norias :)
09:25 PM norias: oh wouldn't polymer concrete be fun to mess with
09:26 PM norias: problem is, i'm learning towards whatever i do eventually being a production machine
09:26 PM XXCoder: epoxy grinite fun
09:26 PM norias: so cast iron is probably the better route
09:26 PM norias: if i could find the same castings tormach uses
09:26 PM XXCoder: depends on what you want, wood or plastics only you can go pure extrusions
09:26 PM norias: i'd buy those
09:26 PM norias: naw
09:26 PM XXCoder: maybe even alum but its limited
09:27 PM pink_vampire: norias: do you know how to scraping?
09:27 PM norias: i'm going for competing with tormach / robodrill
09:27 PM roycroft: that's the thing about a one-off machine
09:27 PM norias: pink_vampire: a little. not well.
09:27 PM roycroft: it's really really expensive to make patterns and get castings made
09:27 PM XXCoder: ohh yeah I recall theres dead car engines cast iron mill machine
09:27 PM roycroft: and when you get the castings, you need to get more than one of each part
09:27 PM norias: pink_vampire: i have no interest in doing box ways
09:27 PM roycroft: and age them before you machine them
09:28 PM norias: roycroft: which is why i thought i might just get durabar and machine it for the prototype
09:28 PM norias: the system performance will be close enough
09:28 PM CaptHindsight: I'm making the production of sand molds cheap-ish
09:28 PM pink_vampire: i did lapping today on the spindle bore for the milling head
09:28 PM norias: CaptHindsight: how so?
09:28 PM roycroft: it might be better to get some old big iron and rebuilt it completely
09:28 PM CaptHindsight: SLA printer with sand and photopolymer
09:28 PM roycroft: maybe even modify the design
09:28 PM XXCoder: norias: nice so its just brs of castiron
09:28 PM roycroft: just use the castings
09:28 PM norias: CaptHindsight: makes sense
09:28 PM roycroft: and do your own thing
09:28 PM norias: XXCoder: yeah
09:29 PM XXCoder: can do butt joints using grinder
09:29 PM norias: roycroft: i'm going for a small machine.
09:29 PM XXCoder: extremely strong joints
09:29 PM CaptHindsight: was just at Design2Part talking to casters in the area
09:29 PM roycroft: buy a used sheldon :)
09:29 PM norias: roycroft: something in the tormach size
09:29 PM CaptHindsight: going to run some samples
09:29 PM roycroft: old, small iron
09:29 PM norias: i'd use tormach castings if i could get them
09:30 PM norias: roycroft: geometry is totally wrong for what i want to do
09:30 PM CaptHindsight: anyone recall any parts of LCNC that use wxPython?
09:30 PM XXCoder: nori you do have access to grinder at work?
09:30 PM XXCoder: im pretty sure yes
09:30 PM roycroft: tom_l recently built a small vertical mill from scratch
09:30 PM norias: XXCoder: what kind?
09:31 PM CaptHindsight: is that what JT uses for stepconfig?
09:31 PM roycroft: you might talk to him when he's around
09:31 PM XXCoder: certainly not hand type
09:31 PM XXCoder: dunno its one that has table that moves in and out while wheel grinds on part. i never used one so dont know about names etc
09:31 PM norias: XXCoder: surface grinder?
09:31 PM XXCoder: probably? heh
09:31 PM roycroft: that's what it sounds like
09:32 PM norias: lol
09:32 PM norias: well, table eliminates cylindrical grinders
09:32 PM norias: so, we're down to surface grinder or jig grinder
09:32 PM roycroft: do big sparks fly out one end, and does it have a magnetic vise?
09:32 PM CaptHindsight: have a machine big enough to clean up castings the size of a Tormach?
09:33 PM XXCoder: https://www.youtube.com/watch?v=npybvhWYklc
09:33 PM XXCoder: certainly surface grinder
09:33 PM roycroft: it would be interesting to get some tormach castings and build a machine that works better than a tormach :)
09:33 PM norias: CaptHindsight: I think I can live with just machined surfaces
09:33 PM norias: CaptHindsight: i don't think they need ground
09:33 PM CaptHindsight: hand lap
09:33 PM norias: eh
09:33 PM norias: why
09:34 PM CaptHindsight: the old world way
09:34 PM norias: yeah
09:34 PM norias: i want to avoid old world
09:34 PM pink_vampire: XXCoder: to surface grind a machine ways correctly you must do it on the same setup,
09:34 PM norias: i am not doing box ways
09:34 PM norias: i'm using linear rails
09:34 PM XXCoder: yeah likely not large enough anyway
09:35 PM pink_vampire: other wise you will have to hand scraped it
09:35 PM CaptHindsight: polymer concrete
09:35 PM norias: eh
09:35 PM norias: maybe
09:35 PM XXCoder: polymer concrete? thats new to me
09:35 PM pink_vampire: epoxy granit
09:35 PM CaptHindsight: polymer granite
09:35 PM XXCoder: oh
09:36 PM norias: they anti-vibe properties are exciting
09:36 PM CaptHindsight: https://ibin.co/2eWjnYtOrXq9.jpg
09:36 PM norias: but, cast iron does pretty good, too
09:36 PM XXCoder: big rocks down to tiny sand yeah it eats vibration hard
09:36 PM XXCoder: add some rubber that dont bounce on bottom support it dont vibrate much I think
09:37 PM norias: XXCoder: do you know why cast iron is used for machine bases instead of steel?
09:37 PM XXCoder: some kind of properity I guess like eating vibration
09:37 PM norias: exactly
09:37 PM XXCoder: and more termal stability?
09:37 PM norias: not really
09:37 PM pink_vampire: on there small machines the problem is too much play between the parts,
09:37 PM norias: it's all about vibration
09:37 PM norias: can you guess why cast iron dampens vibration better?
09:38 PM XXCoder: no idea, wild guess is grainy inside
09:38 PM norias: not a bad guess
09:38 PM norias: carbon content
09:38 PM CaptHindsight: https://www.academia.edu/8322378/Influence_of_Resin_Content_and_Cast_Iron_Powder_Addition_on_Vibration_Characteristics_of_Granite_Epoxy_Composites
09:39 PM norias: CaptHindsight: i know it's good, but is there a good supply chain for doing them?
09:39 PM norias: i.e. if this works, how hard is it to outsource
09:39 PM CaptHindsight: https://www.hindawi.com/journals/jcomp/2013/948745/
09:39 PM norias: that's a big advantage of cast iron
09:39 PM norias: it's proven, and a metric fuck ton of people pour iron
09:40 PM CaptHindsight: norias: I have a gravel quarry near me (stones throw) and I make resins
09:40 PM XXCoder: from what I recall cast iron needs years of temperate changes (if free at outside)
09:40 PM norias: and then when i design the thing
09:40 PM norias: i need to put steel in it
09:40 PM norias: and now i need to think about the differential in thermal expansion
09:40 PM norias: and how that affects things
09:41 PM norias: doable, but still more work
09:41 PM norias: for how much benefit?
09:41 PM XXCoder: nor I was kinda ythinking, note im no engineer, maybe 4 bars of cast iron, make a cross member supported bars of cast iron
09:41 PM XXCoder: with recessed connections for strength
09:42 PM CaptHindsight: let me find the link for you about reinforced polymer concrete machine design and dampening
09:42 PM norias: XXCoder: i'd just buy big sheets of durabar and re-create the shape of a casting
09:42 PM XXCoder: thats why I was thinking grinder to make those recessed notches for cross supports
09:42 PM XXCoder: and grind ends for very flat
09:42 PM norias: CaptHindsight: i get it, but i just don't know if i have the engineering ability to make it work right
09:43 PM CaptHindsight: coincidentally durabar is also right down the street from me
09:43 PM norias: neat
09:43 PM CaptHindsight: was just talking to them at Design2Part last week
09:43 PM norias: i think their process is super cool
09:44 PM XXCoder: man! i need my own shop space
09:44 PM XXCoder: so i can finish my cnc router.
09:44 PM XXCoder: no room, and no will
09:45 PM CaptHindsight: http://www.mech.utah.edu/~me7960/lectures/Topic14-DesignOfMachineStructures.pdf
09:46 PM pink_vampire: norias: you are putting you efforts in the wrong place. instead of damping the vibrations with more weight, you need to make sure the machine joint are the best you can get them, it will damping the vibrations by making the machine more rigid and less likely to flex
09:46 PM norias: pink_vampire: i never said anything about more weight
09:47 PM pink_vampire: to fill the castings with epoxy granite..
09:48 PM CaptHindsight: pink_vampire: read the pdf posted ^^
09:48 PM norias: pink_vampire: no, the debate is epoxy granite vs. cast iron
09:48 PM norias: which, i think will have about the same mass
09:48 PM CaptHindsight: Constrained Layer Damping
09:49 PM CaptHindsight: https://ibin.co/2eWjnYtOrXq9.jpg
09:49 PM norias: CaptHindsight: i dig the PDF. thanks.
09:50 PM XXCoder: i remember reading about reforced bars. definitely interesting
09:50 PM XXCoder: can be extremely strong, and it actually unbends
09:50 PM CaptHindsight: he ran a bunch of tests and took measurements
09:51 PM CaptHindsight: Flexible constraining layer thickness – wide range of
09:51 PM CaptHindsight: standard tubes can be used as support tube, wall
09:51 PM CaptHindsight: thickness is no longer a design constraint
09:51 PM CaptHindsight: Concrete provides additional damping
09:51 PM CaptHindsight: Cheap
09:51 PM CaptHindsight: Fast
09:51 PM pink_vampire: ok, i think cast iron age better, but epoxy granite is more accessible to the home shop and you can use of the shelf parts to make you ways very precise
09:51 PM norias: pink_vampire: i can also just buy durabar and machine it
09:52 PM CaptHindsight: you're no fun :)
09:52 PM pink_vampire: have fut machining cast iron in you home shop
09:52 PM pink_vampire: fun*
09:52 PM XXCoder: that odf biut too advanced for me!
09:52 PM XXCoder: pdf bit
09:52 PM norias: pink_vampire: i won't. i have places i can rent machine time.
09:53 PM CaptHindsight: all depends on what you have for tools and your skills
09:53 PM norias: it's all about what makes the best commercially viable machine in the end
09:54 PM XXCoder: indeed
09:55 PM pink_vampire: I think my next mill will be something that is off the shelf, the diy benchtop are nice and good, but if you want to run alot of parts, you need a machine that can deliver that
09:55 PM XXCoder: compination of above basically
09:55 PM norias: pink_vampire: what's your budget?
09:56 PM pink_vampire: and those days you can get very decent used machine for less money then pure diy vmc
09:56 PM pink_vampire: lets say 10K
09:57 PM norias: i think tormach's 440 is around there
09:57 PM norias: actually, the 770M with no additional stuff
09:57 PM pink_vampire: the 440 is smaller then the g0704, and the spindle on it is a bad joke
09:57 PM norias: 10k RPM @ 1.5 HP
09:58 PM pink_vampire: 10K that you can stop with your hand almost
09:58 PM norias: I think 1.5HP is the max you can get out of 120V 20A
09:58 PM Wolf__: tormach is somewhat of a bad joke imo
09:58 PM XXCoder: https://www.youtube.com/watch?v=r1xN7f3lBwU
09:58 PM norias: Wolf__: my point, exactly.
09:58 PM XXCoder: near end, it has cnc machine using 3 cnc machines.
09:59 PM pink_vampire: I run the 440 in a maker space here, and it is sooo small and weak
09:59 PM norias: 440 is like .75 HP
10:00 PM norias: humans can generate about 1/3 HP with treadles
10:00 PM Wolf__: imo tormach is perfect for the hobbiest shop where its going to collect more dust than make chips
10:00 PM pink_vampire: and for a benchtop with r8 and steppers, just get g0704 of pm25 and have fun with it
10:00 PM XXCoder: tormach reminds me of office mill haas
10:00 PM XXCoder: i hated office mill haas machines.
10:00 PM norias: XXCoder: hah. office mill is more money, i think.
10:00 PM norias: but has cat 40?
10:01 PM norias: and maybe 5HP spindle
10:01 PM norias: maybe not
10:01 PM XXCoder: lol cat40 you could hide 4 of its toolholders in cat40
10:01 PM norias: anyway
10:01 PM norias: f this, i need to sleep
10:01 PM XXCoder: you can hide one in your fist if its not holding a tool!
10:01 PM XXCoder: night :)
10:01 PM pink_vampire: good night
10:03 PM pink_vampire: I feel lucky to get nice blue chips from my g0704 after i did the servo spindle conversion
10:03 PM XXCoder: nice!
10:03 PM XXCoder: blue means its cutting very well indeed
10:04 PM pink_vampire: it is much stronger then the original spindle, but the same speed
10:04 PM pink_vampire: https://i.imgur.com/YeHcpLs.png
10:04 PM XXCoder: btw https://www.aliexpress.com/item/1Pcs-precision-0-001-high-speed-toolholder-ISO25-ISO20-ER20-ER16-Collet-Chuck-Balance-G2-5/32971991330.html
10:04 PM XXCoder: its that small, iso 20
10:06 PM Tom_L: what is the slit in those for??
10:06 PM pink_vampire: 7mm DOC, full diameter of the endmill, 69mm/min cut like a charm
10:06 PM XXCoder: toolholder maybe
10:06 PM Tom_L: pink_vampire, what spindle?
10:07 PM XXCoder: no, no idea lol
10:07 PM pink_vampire: the servo spindle i did
10:07 PM pink_vampire: 3000 RPM with 1:3 belt
10:07 PM Tom_L: XXCoder generally they have threaded ends
10:07 PM Tom_L: pink_vampire what motor?
10:08 PM pink_vampire: one sec I will take a picture
10:08 PM XXCoder: tom lol kinda tempted to buy one
10:08 PM Tom_L: i don't have anything to put it in
10:08 PM CaptHindsight: https://imagebin.ca/v/2RuHAsYVLA7N I'll sell you this one cheap
10:09 PM XXCoder: shipping makes it not worth it even free lol
10:09 PM CaptHindsight: flat rate priority :)
10:09 PM Tom_L: CaptHindsight are those 6" vises?
10:09 PM CaptHindsight: yeah
10:09 PM CaptHindsight: Shars
10:10 PM Tom_L: fairly good size
10:10 PM XXCoder: not kurt?
10:10 PM CaptHindsight: nope
10:10 PM Tom_L: i'm happy with my shars vise
10:10 PM XXCoder: man im kurt that its not kurt
10:10 PM XXCoder: kidding
10:10 PM CaptHindsight: Shars is local so I can pick good ones
10:10 PM XXCoder: only jaws i have experence with is kurt and cheap shit drill vise heh
10:11 PM pink_vampire: https://i.imgur.com/NRJ2DZH.png https://i.imgur.com/eK5MAc6.png
10:11 PM pink_vampire: this is my servo spindle
10:11 PM CaptHindsight: https://www.shars.com/6-690v-cnc-milling-machine-vise-0-0004-1
10:11 PM CaptHindsight: $320.00 ea
10:12 PM XXCoder: around $100 cheaper than kurt if I recall right
10:12 PM Tom_L: https://www.shars.com/products/workholding/vise/4-440v-cnc-milling-machine-vise-0-0004-1
10:12 PM Tom_L: i've got that one
10:12 PM CaptHindsight: after I got mine they had these https://www.shars.com/products/workholding/vise/6-660u-cnc-milling-machine-vise-0-0004-1
10:13 PM CaptHindsight: you can place them closer together
10:13 PM pink_vampire: Tom_L: this is the motor https://www.automationtechnologiesinc.com/products-page/nema-34-dc-servo-motor/4-axis-nema34/
10:13 PM Tom_L: on the spindle?
10:13 PM CaptHindsight: automationtechnologiesinc is also nearby so i can complain about my bad parts in person :)
10:13 PM pink_vampire: correct
10:14 PM Tom_L: what's the cost of one and one driver?
10:14 PM Tom_L: i'd have to swap the psu too though...
10:14 PM Tom_L: :(
10:14 PM Tom_L: i'd like to find a 110v driven servo or spindle motor
10:15 PM pink_vampire: no idea, i got this set with the 4 motor and 4 drivers, so 3 axis machine and one that i wanted just in case..
10:15 PM pink_vampire: Tom_L: i drive it with the old controller with 90V no problem
10:15 PM Tom_L: are those gecko drivers?
10:16 PM pink_vampire: i have a selector switch servo / DC
10:16 PM pink_vampire: yeah, and they are ok, but I think now it will be smarter to get something like the clear path
10:17 PM CaptHindsight: https://www.ebay.com/p/LEESON-098009-00-90-Volt-DC-2500-RPM-3-4-HP-Electric-Motor-56c-Frame/840993895

10:18 PM CaptHindsight: oops sorry thats a 180V
10:18 PM pink_vampire: I can't get it to run 1000rpm with the g302x, so the servo is high resolution, but limited to about 100 rom, that is fine for tapping and stuff like that
10:19 PM CaptHindsight: 90V https://www.ebay.com/p/DC-Motor-1hp-56c-90vdc-1750rpm-TEFC-Permanent-Magnet/1531657304
10:19 PM Tom_L: low rpm
10:19 PM pink_vampire: Tom_L: the cheapest is to go on craigslist on the free stuff and get a thread mill
10:20 PM XXCoder: or maybe washer machine? lol
10:21 PM Tom_L: i had one of those with the control
10:21 PM Tom_L: someone said it wouldn't work that well
10:21 PM pink_vampire: XXCoder: also an idea
10:21 PM pink_vampire: what do you mean?
10:22 PM CaptHindsight: https://www.ebay.com/itm/YUASA-HIGH-SPEED-SPINDLE-MULTIPLIER-521-701/323738219596
10:23 PM CaptHindsight: Tom_L: do you have 220V?
10:23 PM CaptHindsight: https://www.ebay.com/itm/Perske-High-Speed-Spindle-Motor-23K-RPM-1-35HP-220V-VS31-09-24/192902484071
10:23 PM Tom_L: yup
10:23 PM CaptHindsight: $150
10:24 PM pink_vampire: CaptHindsight: I think you need a vfd for it
10:24 PM pink_vampire: Voltage 220V Amps 4 HZ 400 23,100 RPM
10:25 PM CaptHindsight: a bargain if the bearings are good
10:26 PM pink_vampire: or it will be a reason to also get a press
10:26 PM XXCoder: you can make your own
10:26 PM XXCoder: bolts and specific designed grippers
10:27 PM pink_vampire: XXCoder: naa harbor freight with 20% off and I'm good to go
10:29 PM pink_vampire: https://i.imgur.com/wO2UIE6.png even better
10:30 PM XXCoder: lol ok
10:30 PM XXCoder: how much is that press
10:31 PM CaptHindsight: https://www.harborfreight.com/20-ton-shop-press-32879.html
10:32 PM pink_vampire: https://i.imgur.com/r4kdzEt.png
10:32 PM CaptHindsight: i recall going through 4 boxes to find one with good welds...
10:32 PM pink_vampire: 189.99 > 149.99
10:32 PM CaptHindsight: then i get it home and the spacing between the angles is too close so the return springs don't fit :(
10:32 PM XXCoder: geez
10:33 PM CaptHindsight: yeah
10:33 PM XXCoder: make it extreme guys made one thats insanely powerfyk
10:33 PM roycroft: i've heard lots of stories about people who have broken those 20 ton shop presses
10:34 PM CaptHindsight: https://www.youtube.com/watch?v=JEGKucnHHXc
10:34 PM CaptHindsight: yeah wear your safety glasses when using anything by HF
10:34 PM XXCoder: capt heh when elio bought a factory, it come with one million ton press
10:34 PM roycroft: i have a 12 ton hf press
10:34 PM roycroft: i've had it for ages
10:34 PM XXCoder: yes, thats million tons, not million pounds
10:35 PM pink_vampire: roycroft: for the stuff i'm doing the vise is more then fine
10:35 PM roycroft: it works ok
10:35 PM XXCoder: its so heavy and strong it must be put on special very thick slab of concerete.
10:35 PM roycroft: but i don't think i've ever pushed it anywhere near its stated capacity
10:36 PM XXCoder: https://www.eliomotors.com/wp-content/uploads/2015/01/Press1.jpg
10:37 PM XXCoder: thats the million ton press
10:37 PM roycroft: i bet apple have some of those million ton presses
10:37 PM roycroft: that's how they can make the iphone so thin
10:37 PM XXCoder: lol
10:37 PM CaptHindsight: nah it's the little fingers on children
10:37 PM pink_vampire: XXCoder: I will give them a call and ask to press some bearings
10:38 PM XXCoder: lol
10:38 PM CaptHindsight: they can get into tighter spaces
10:38 PM XXCoder: turn bearings into 2d bearings ;)
10:38 PM pink_vampire: LOLL
10:39 PM pink_vampire: "2d bearings" I like that
10:39 PM XXCoder: :)
10:41 PM pink_vampire: maybe I need to ask fastenal about "2d bearings" they always ask me if i find everything on the website
10:41 PM roycroft: we have a fastenal in eugene
10:42 PM roycroft: every time i look something up on their website that i need right away it says "direct ship from manufacturer"
10:42 PM pink_vampire: my last press job that i did https://i.imgur.com/NlrTjIq.png https://i.imgur.com/MIuz1mw.png
10:42 PM pink_vampire: but they get it in 1-2 days
10:42 PM roycroft: so i don't know why they bother with a brick and mortar store
10:43 PM pink_vampire: and cheaper then china!
10:43 PM pink_vampire: i just pickup in the store
10:43 PM CaptHindsight: roycroft: yeah, the stores only stock cleaning supplies and popular sized fasteners
10:44 PM roycroft: so they're useless
10:45 PM Wolf__: fastenal’s prices arent even that good either, I go to mcmaster and just have what I need shipped to my shop now
10:45 PM roycroft: we have eugene fastener, who have a pretty large inventory
10:45 PM CaptHindsight: Wolf__: no bargains at fastenal
10:45 PM roycroft: what they don't have in stock i usually get from mcmaster
10:46 PM roycroft: fastenal sound like grainger, but without the inventory
10:46 PM CaptHindsight: mcmaster is also nearby, i can drive there and deal with cranky counter help :)
10:46 PM roycroft: mcmaster are in reno
10:46 PM pink_vampire: the bearings in fastenal are very cheap
10:46 PM roycroft: which is two days ground from here
10:47 PM CaptHindsight: the mcmaster near here has a giant conveyor belt like an amusement park
10:47 PM pink_vampire: i don't like the gray mcmaster website
10:47 PM roycroft: it's easy to find stuff on their website
10:47 PM roycroft: and the prices are good
10:47 PM roycroft: and they have the kind of stuff i buy in stock all the time
10:48 PM roycroft: but i've never seen a grey mcmaster website
10:48 PM roycroft: so maybe you're looking at a different mcmaster
10:48 PM pink_vampire: all the images
10:48 PM CaptHindsight: https://www.mcmaster.com/machine-keys
10:49 PM CaptHindsight: metal is grey :)
10:49 PM CaptHindsight: thery did that to save bits
10:49 PM CaptHindsight: they even
10:50 PM CaptHindsight: 8 bit grey vs lord knows how mnay bits for color , like 3x as much
10:50 PM CaptHindsight: when i was a kid we didn't even have bits for color
10:51 PM CaptHindsight: or grey
10:52 PM pink_vampire: and I like the fact the you can buy stuff in fastenal by "each"
10:52 PM roycroft: i really like that they have 2d and 3d cad drawings of most of their parts
10:52 PM pink_vampire: if i need just 1-2 set scres, and stuff like that i pay cents for it
10:53 PM roycroft: see, i'm the opposite
10:53 PM roycroft: for the majority of fasteners that i get, if need 1 or 2 of something that i don't stock i buy a quantity, like 25 or 100
10:53 PM pink_vampire: roycroft: the 3d models it what make me start working with them
10:53 PM roycroft: and the next time i need that fastener i'll have it in stock
10:54 PM roycroft: do that for 40 or so years and you'll have a pretty good inventory of hardware :)
10:55 PM pink_vampire: but I'm talking about odd stuff like drive screws, and metric set screws and stuff like that
10:55 PM roycroft: yes, for really odd things i don't do that
10:55 PM roycroft: metric set screws are not odd though
10:55 PM roycroft: they're fairly commonly used
10:56 PM roycroft: but hard to find locally
10:56 PM pink_vampire: I got M8 6mm and 8mm this is not a very common size for me
10:56 PM CaptHindsight: roycroft: no matter what you have in stock you'll need some you don't have :)
10:56 PM pink_vampire: almost all the time I'm using 10-32
10:56 PM roycroft: capthindsight: yes, i'm always buying fasteners
10:56 PM CaptHindsight: grainger had a $1/box sale
10:57 PM CaptHindsight: they often do
10:57 PM roycroft: but i don't run to a local hardware store every time i need a common fastener
10:57 PM pink_vampire: I never got any fastener in grainger
10:58 PM roycroft: i just bought some 3/8-16 x 7/8" socket head screws
10:58 PM roycroft: i have 3/4" and 1"
10:58 PM roycroft: but i can't have the screws protrude, so 1" was out
10:58 PM roycroft: and 3/4" did not grab well enough to make me happy
10:59 PM pink_vampire: I need 5 conductor 16 or 18 awg cable 4' will be fine
11:00 PM pink_vampire: any idea where to get some?
11:00 PM roycroft: the internet?
11:00 PM CaptHindsight: 1" with washers ")
11:00 PM roycroft: on the head side there is also very little clearance
11:00 PM roycroft: i almost got low profile heads
11:01 PM pink_vampire: the only place i saw something like that was mouser, and the price was crazy
11:01 PM roycroft: is this for stepper motors or something?
11:01 PM CaptHindsight: the hardware store near here stocks a pretty good assortment, the home remodeling stores don't carry much
11:02 PM CaptHindsight: check the 3d printer supply websites
11:02 PM pink_vampire: no, it is for ac motor, but yeah, same idea, 2coils and ground
11:02 PM CaptHindsight: what is the place for hobby electronics in NYC?
11:02 PM pink_vampire: none
11:02 PM roycroft: adafruit
11:02 PM CaptHindsight: adafruit and similar
11:03 PM CaptHindsight: sparkfun
11:03 PM pink_vampire: those are online stores with over priced stuff
11:04 PM CaptHindsight: you want 4ft
11:05 PM pink_vampire: https://www.ebay.com/itm/351744627477 this is nice, but not sure what is the voltage rating
11:13 PM pink_vampire: https://www.wiringproducts.com/trailer-cable
11:13 PM pink_vampire: what is the voltage rating on those cables??
11:14 PM roycroft: probably pretty low
11:15 PM roycroft: if they're for trailers
11:15 PM pink_vampire: i need it for 110V ac
11:15 PM roycroft: that stuff almost certainly will not work
11:15 PM roycroft: and do you need shielded pairs?
11:16 PM pink_vampire: no just 4 wires and ground
11:19 PM pink_vampire: roycroft: https://www.ebay.com/itm/172877008917 this is the cable!!!
11:19 PM pink_vampire: WOW 35$ shipping
11:19 PM pink_vampire: why
11:20 PM XXCoder: wow shipping bomb
11:20 PM XXCoder: though if order huge amount of feet it gets cheaper
11:20 PM pink_vampire: I need 4'
11:20 PM pink_vampire: lol
11:20 PM XXCoder: yeah elsewhere it is then :)
11:21 PM pink_vampire: it will be 9.79$ per foot LOL
11:21 PM pink_vampire: almost like pure gold
11:21 PM XXCoder: geeez. order 10 feet or something. make shipping worth it
11:22 PM XXCoder: use rest elsewhere in future
11:23 PM XXCoder: found 250 feet for 219 bucks. free shipping lol
11:23 PM XXCoder: found another 250 feet but only 203 bucks shipped
11:24 PM XXCoder: LOL!! 500 feet one for 277 bucks
11:24 PM pink_vampire: 250 feet it will make the milling head very close to wireless
11:24 PM XXCoder: all wire you can eat
11:25 PM pink_vampire: i think I will just get 18 awg and heat shrink
11:35 PM roycroft: you can buy cable sheathing and pull your own wires
11:35 PM XXCoder: isnt 18 awg smaller diameter wires than 16?
11:36 PM roycroft: it is
11:36 PM pink_vampire: roycroft: this is a grate idea!
11:36 PM roycroft: 18ga is rated at 5a, 16ga 10a
11:36 PM roycroft: in a cable or conduit
11:37 PM roycroft: 10a/15a in a chassis
11:37 PM XXCoder: is it still above max amp your use will reach?
11:37 PM XXCoder: pink_vampire: there is LOT of cheap single 16 awg wires on ebay.
11:37 PM pink_vampire: it is 0.14kw motor
11:38 PM pink_vampire: about 1.3A 110V
11:39 PM XXCoder: so 18 awg is plenty of room if its 5a
11:39 PM pink_vampire: the original cable is 18 awg
11:40 PM roycroft: i don't know the maximum voltage of irrigation control cables, but they are 18ga 7 conductor
11:40 PM roycroft: probably not high enough voltage though - irrigation systems run on low voltage dc
11:41 PM pink_vampire: Thermostat Wire is rated for main voltage, and it is 18/5, but it is solid
11:41 PM roycroft: oh
11:42 PM roycroft: i don't think you stipulated that you need stranded wire
11:42 PM roycroft: irrigation control cables are solid wire
11:43 PM pink_vampire: it is not a good idea to use solid wire for milling head that move up and down
11:43 PM XXCoder: yeah bend ratings
11:43 PM roycroft: i did not know the application
11:44 PM pink_vampire: right now the milling head have only 4 wires, so 2 coils share the same wire,
11:45 PM pink_vampire: if i split it to 5 wires i will be able to change the direction of the motor
