12:31 AM XXCoder: rebecca: I saw couple machines with it
12:34 AM rebecca: oooohkay. are the builds documented anywhere?
12:34 AM XXCoder: nah it was posted pictures in here
12:34 AM rebecca: ah
12:34 AM rebecca: ok
12:35 AM rebecca: wondering about best approach to wiring them
12:35 AM XXCoder: if possible, I would make it so open equals triggered
12:35 AM XXCoder: that way wire breakage dont cause machine to smash into end
12:36 AM rebecca: yeah, NC sensors is what i was intending
12:36 AM XXCoder: unfortunately thats end of my possible suggestion. I did use induction but it was for 3d printer, and was pretty hacky.
12:36 AM rebecca: but wiring them up in a way that is noise immune and not liable to fry the microcontroller is where i'm hoping to find some help.
12:37 AM rebecca: ah
12:39 AM XXCoder: I wonder if diodes would make it block feedback?
12:40 AM XXCoder: possibly optical couplers? think power cant cross that
12:41 AM rebecca: diodes have been suggested.
12:41 AM rebecca: yeah
12:41 AM rebecca: ideally there is a breakout board i can buy that solves this problem
12:45 AM XXCoder: yeah. my 3d printer I didnt, I just bug wired volt splitter to get voltage for signal low enough and just connected it
12:45 AM XXCoder: pretty bad lol
12:45 AM jesseg: I wonder about using piezo disk speakers as limit switch sensors...
12:46 AM rebecca: XXCoder: well, if it does the job :)
12:46 AM jesseg: They can produce extremely repeatable contact signals
12:47 AM rebecca: XXCoder: i'm in the process of building/designing a machine (which i may sell versions of in the future) and will be upgrading a friends machine. so i'm really looking for a professional/repeatable solution here
12:48 AM XXCoder: indeed no volt halver lol
12:49 AM rebecca: not dead bug wired at least :)
12:51 AM XXCoder: yeah
12:52 AM rebecca: might have to roll my own pcb with opto isolators but would prefer to throw money at that aspect of it. so busy with CAD
12:53 AM XXCoder: got a router? could just mill pcb, though thats small scale only prod
12:53 AM rebecca: yeah, i have a small CNC that could do that. but want to avoid that hassle
12:54 AM XXCoder: yeah
12:55 AM rebecca: and imho router cut pcb is not quite professional without being tinned and sealed which is more work
12:56 AM rebecca: good for quick prototype though
12:57 AM roycroft: there are places where you can email them a gerber file and a few weeks later however many pcbs as you want show up at your door
12:57 AM rebecca: i know
12:58 AM jesseg: rebecca, I've been tinning my router cut PCBs, and sealing them with clear conformal coating, but wood finish works too. if I want them green I color them with a green sharpie first. Actually I have some of that UV cured solder resist from China/Ebay that I need to try too.
12:59 AM rebecca: cool, and i'm sure they are wonderful. i'm just busy as heck and want to avoid that hassle myself
12:59 AM jesseg: Also recently started using the brass rivets for through holes. They are a pain though. Also experimented with electroplating through holes, but never could get that working right. It did work *once* and it was very nice
01:00 AM jesseg: nah they aren't wonderful they as cheesy as a block of chedder
01:00 AM jesseg: but they are quick and cheap :P
01:01 AM jesseg: and it allows me to do several iterations in one day if I'm having an average mistakish day :P
01:01 AM rebecca: pcb layout aint my forte
01:03 AM jesseg: ahh
01:09 AM rebecca: hmmmm, might just use something like sparkfun opto isolator modules
01:19 AM roycroft: using brass rivets as vias doesn't seem like it would work out too well
01:21 AM jesseg: roycroft, you mean because of the effort to install them, or the long term thermal stability?
01:21 AM roycroft: the latter, primarily
01:21 AM jesseg: either way I agree, not idea. But cheap and effective for home prototyping :P
01:21 AM jesseg: not ideal, I mean.
01:21 AM roycroft: getting them tight enough to hold without damaging the pcb would be a challenge
01:21 AM roycroft: besides, brass is far from an ideal conductor :)
01:22 AM roycroft: for prototyping it could be ok
01:22 AM jesseg: well they are very small and thin, so they pound pretty flat with a small hammer
01:22 AM roycroft: they would also be rather expensive for production
01:22 AM roycroft: but again, that's not really an issue for prototyping
01:22 AM XXCoder: gold circuits :P
01:22 AM jesseg: LOL no way for production.
01:22 AM roycroft: gold rivets for vias
01:22 AM roycroft: now there's an idea
01:23 AM jesseg: I would much much rather electroplate my holes. But the step of making them initially conductive so you can electroplate is severely problematic for the hobbyist :P
01:24 AM jesseg: btw you can also get little copper rivets for PCB through holes, but they are more expensive :P
01:25 AM jesseg: https://www.ebay.com/itm/Hollow-Copper-Rivets-for-PCB-GND-on-M-W-boards-200-pcs/381669919035?hash=item58dd4cc93b:g:xUYAAOxyXWdQ7nR2
01:27 AM jesseg: hmm there is more selection of copper rivets for PCB on ebay then there was last year when I was looking.
01:37 AM IchGucksLive: morning from germany
01:38 AM IchGucksLive: rebecca, still online
01:38 AM rebecca: hey IchGucksLive
01:38 AM IchGucksLive: is it pcb only or more to come
01:39 AM rebecca: hmm?
01:39 AM rebecca: one off or multiple?
01:39 AM IchGucksLive: i make small mills for education homebuild
01:40 AM IchGucksLive: http://tv-profi-gmbh.de/masch_baumh_k.jpg
01:40 AM rebecca: okay
01:40 AM IchGucksLive: this are quite good for PCB
01:40 AM IchGucksLive: as they are desktop
01:40 AM IchGucksLive: fit the standard EU Fr4
01:40 AM rebecca: awww, a little herd of CNCs :D
01:41 AM rebecca: i have my own little 3020 that could make PCB
01:42 AM IchGucksLive: rebecca, and you are retrofitting it
01:42 AM IchGucksLive: to tb6600
01:42 AM IchGucksLive: and 5axis bob
01:42 AM IchGucksLive: with 36V psu
01:43 AM rebecca: nope. building a new, much bigger machine
01:43 AM IchGucksLive: HGH rail set
01:43 AM rebecca: but i want to use inductive proximity sensors but safely and professionally
01:43 AM IchGucksLive: for limit
01:43 AM rebecca: yes
01:44 AM IchGucksLive: https://www.ebay.de/itm/Induktiver-Naherungsschalter-Naherungssensor-LJ12A3-4-Z-BX-Three-Wire-Schlieser/192541304164
01:44 AM rebecca: hb20 guides. 1400 x 1200 x 600
01:44 AM IchGucksLive: THIS ones
01:44 AM IchGucksLive: 600 Z is quite long
01:45 AM rebecca: yeah. one of the jobs will be machining 3d surface for architects so i need large Z
01:45 AM rebecca: also I am choosing larger than normal carriage displacement for less play
01:45 AM IchGucksLive: http://heimwerkermarkt-tretter.de/holzcnc.jpg This is mine at 2K cost
01:46 AM rebecca: ahhh, nice. i have seen that before. has inspired my design a little :D
01:46 AM rebecca: i will be using plywood too for mine. cut on an industrial cnc
01:46 AM IchGucksLive: i woudt go for a different
01:47 AM IchGucksLive: on more then 300mm Z
01:47 AM rebecca: probably using 10mm Al plate for Z axis though
01:47 AM rebecca: with buttress
01:47 AM IchGucksLive: https://www.youtube.com/watch?v=BbVUEcMGrdE
01:47 AM IchGucksLive: this is my 5Axis
01:48 AM IchGucksLive: it has cabability of 600mm Z movement
01:48 AM rebecca: aaaanyway. this might be the solution to my problem: https://www.banggood.com/A87-4-Channel-Optocoupler-Isolation-Module-High-And-Low-Level-Expansion-Board-For-Arduino-p-1195867.html
01:48 AM rebecca: for isolating the inductive sensors
01:48 AM IchGucksLive: RUN the X on table movement
01:48 AM IchGucksLive: and keep Frame FIX
01:48 AM IchGucksLive: so you are up a better way
01:49 AM IchGucksLive: if y<ou put the frame behind the Y you can run a TC
01:49 AM IchGucksLive: toolChanger
01:49 AM IchGucksLive: as Y moves outsaide workarea
01:49 AM rebecca: nope. my CNC has to fit in a small room and moving gantry gives me the biggest space
01:49 AM rebecca: i have purchased my linear motion components so no changing the design now!
01:50 AM IchGucksLive: i peronly got in trouble while extending Z above 200mm
01:50 AM IchGucksLive: even the HGH Hiwin have then to mutch Flex
01:50 AM rebecca: i think using aluminium Z plate + larger than normal Y carriage displacement will avoid problems
01:51 AM IchGucksLive: mine are 250mm apart
01:51 AM IchGucksLive: no way to cope with 400mm Z depth
01:51 AM IchGucksLive: it flexes up to 0,2mm
01:52 AM IchGucksLive: witch get reonances and hard rough
01:52 AM rebecca: my carriages on Z will be further apart than yours
01:53 AM IchGucksLive: http://tv-profi-gmbh.de/fit_we.jpg
01:53 AM IchGucksLive: this a a mahagoni aprt made on it
01:54 AM rebecca: ok
01:54 AM IchGucksLive: rebecca, i made a personly formula 2/3 of Z movement rail square
01:54 AM IchGucksLive: is best to go !:! is better
01:55 AM IchGucksLive: 1:1
01:55 AM IchGucksLive: but not practicly
01:55 AM rebecca: hehe
01:55 AM rebecca: 2/3 sounds about right for what i have in mind
01:55 AM IchGucksLive: if the Z is a 4 Rail system it helps alot
01:56 AM IchGucksLive: ask fragalot he deald with it and got nice outcome
01:56 AM IchGucksLive: rebecca, is it a SBR system on that railsize
01:57 AM rebecca: SBR?
01:58 AM IchGucksLive: https://www.ebay.de/itm/DE-Stock-SBR16-Linear-rail-set-3-Ballscrew-RM1605-350-650-1050mm-3-BK-BF-Nut-CNC/253168250579
01:58 AM rebecca: oh right. no, i'm using the linear slides
01:58 AM rebecca: https://www.aliexpress.com/snapshot/0.html?spm=a2g0s.9042647.6.2.89c04c4dKcctVs&orderId=92270168195686&productId=32884450988
02:00 AM IchGucksLive: rebecca, that is expensice
02:00 AM IchGucksLive: ratmotors sell in the usa for 300
02:00 AM rebecca: <- australia
02:02 AM IchGucksLive: https://www.ebay.com.au/itm/1-5KW-AIR-COOLED-SPINDLE-MOTOR-1-5KW-VFD-HIGH-SPEED-ENGRAVING-MILL-GRIND-NEWEST/263718632674
02:03 AM rebecca: ok?
02:04 AM rebecca: not 2.2kW
02:04 AM rebecca: also.. i purchased my kit already so alternate options don't really help :P
02:04 AM IchGucksLive: ok
02:04 AM IchGucksLive: i woudt not go 2,2
02:05 AM IchGucksLive: 2,2kw is the power cord 240V max
02:05 AM rebecca: also, it's a er11 collet. i wanted er20 so i can run 1/2 inch tooling
02:05 AM IchGucksLive: ER16 can be done
02:05 AM IchGucksLive: on 1.5
02:06 AM IchGucksLive: so your mashine will not fit the 1 power cord mesurments
02:06 AM IchGucksLive: you need 2 power lines
02:07 AM IchGucksLive: or go 16A 380V
02:08 AM IchGucksLive: http://heimwerkermarkt-tretter.de/5achs_elek.jpg THIS and VFD outsine is 240Max
02:09 AM IchGucksLive: http://heimwerkermarkt-tretter.de/schrank.jpg THIS is 380V powerd
02:09 AM IchGucksLive: im off 2 garden rebecca
02:09 AM rebecca: yeah, i know it's a lot of power but controller can be configured to deliver less than max power
02:10 AM rebecca: okay, bye :)
02:10 AM IchGucksLive: does not fit your need
02:10 AM IchGucksLive: if you go for 1,3Kw as you need you looose so many force on china
02:11 AM IchGucksLive: as the High Frequency spindle is logerithmic torque
02:11 AM rebecca: i can get 3 phase power if needed
02:11 AM IchGucksLive: about 20% on Half powermanagment
02:12 AM IchGucksLive: rebecca, if you do not have the Driver go for the DM556
02:12 AM IchGucksLive: if you dont plan to go high speed HS85
02:12 AM IchGucksLive: HSS86
02:12 AM rebecca: i'll see how it performs and decide then
02:12 AM IchGucksLive: best for Wood mashines at this day
02:13 AM IchGucksLive: ok im off
02:16 AM gloops: here on windows...great
02:17 AM gloops: half an hour of asking for irrelevant info to sync everything ive got, and now cant get on ebay lol
02:17 AM XXCoder: yayy heh
02:17 AM XXCoder: wanted the cookies eh ;)
02:18 AM gloops: not taking password lol
02:18 AM XXCoder: talking about that old joke: come over to dark side, we have cookies
02:19 AM gloops: well, ill have to sort that later, only got it to try and run fusion 360
02:33 AM gloops: but installing 123D first - may do what i want and not require becoming a cloud slave to autodesk
02:35 AM XXCoder: cool
02:36 AM skunkworks: I am trying to get video pass through on my laptop working. (to run fusion in a vm)
02:36 AM skunkworks: it isn't going well
02:40 AM gloops: well, 123d has loaded, not sure how this does much at all though, looks very basic but will study later
02:44 AM gloops: still on the cloud though, i thought it was a standalone app - sign in to import model heh
02:44 AM gloops: 'sign in so we can access your projects'
02:44 AM gloops: disturbing requests after being on linux
02:46 AM Deejay: moin
03:19 AM RyanS: is this process called line boring? https://youtu.be/bPPeROCBn3w?t=1480
03:21 AM fragalot: no
03:21 AM XXCoder: is it some sort of inverse lapping?
03:21 AM fragalot: oh wait it's the other way 'round than I thought :P
03:21 AM fragalot: it is line boring
03:22 AM XXCoder: what the heck is guy doing
03:22 AM fragalot: line boring, he's got a HSS cutter mounted in the side of that bar
03:23 AM XXCoder: whats ultimate goal of that? sizing hole?
03:23 AM fragalot: yes
03:23 AM fragalot: you get a very accurate bore doing it like this
03:23 AM XXCoder: interesting
03:25 AM miss0r: goodmorning :D
03:25 AM fragalot: mornin' miss0r
03:25 AM miss0r: I went to bed at around 21:00 last night, and slept till 09:00
03:25 AM fragalot: so it turns out I won't be milling the mill after all today because the other guy got a rush job in and needs those machines >.>
03:25 AM miss0r: 12 hours.. I must have needed it
03:25 AM fragalot: damn him for earning money
03:25 AM miss0r: damn
03:25 AM fragalot: :P
03:26 AM miss0r: Have you gotten the cutter in?
03:26 AM fragalot: i've got ONE cutter in
03:26 AM fragalot: the flat HSS one
03:26 AM miss0r: :S
03:26 AM miss0r: What about that shell mill?
03:26 AM fragalot: he said to bring it in to work on monday and he'd EDM a pocket into it
03:26 AM fragalot: the shell mill will probably get here on monday
03:27 AM miss0r: What is the pocket for?
03:27 AM * miss0r don't get it
03:27 AM fragalot: https://photos.app.goo.gl/WmeGtJQA4ZBkygAd9 <= that's the one I have, with the adapter I made
03:27 AM fragalot: miss0r: the pocket is to fit the nut for a 27mm holder
03:27 AM RyanS: Im making a toolpost mount ball turner and I need a 80mm long bushing housing 23mm -0, +0.023 bore. line bore it?
03:28 AM fragalot: RyanS: line bore + lap
03:28 AM miss0r: whats wrong with the holder you made? it looks fairly decent
03:28 AM miss0r: or use a boring bar...
03:28 AM fragalot: miss0r: he prefers to use the proper holder for rigidity, rather than this adapter in an ER collet
03:28 AM miss0r: its only 80mm deep, and a fairly large bore
03:29 AM miss0r: fragalot: ha... it looked tapered in the photo
03:29 AM fragalot: it's not :P
03:29 AM miss0r: Indeed. It should have a proper holder. That a fairly large diameter for something chinsy
03:30 AM fragalot: the shaft is a nice 24.994mm, and the part going into the cutter is 27.024, with the hole in the cutter being 27.020
03:30 AM gloops: 23mm, hmm, you could get a 20mm boring bar down that, with a sliver of hss to cut with, 20mm should be steady to 80mm depth
03:30 AM RyanS: it always seems to taper when boring bar
03:31 AM fragalot: that won't be any better when line boring
03:31 AM fragalot: that's a machine defect
03:31 AM miss0r: OR
03:31 AM gloops: or just get the right size reamer
03:31 AM miss0r: you are hitting the boring bar :)
03:31 AM miss0r: gloops: indeed
03:31 AM miss0r: bore it close to the size and use a reamer
03:32 AM miss0r: I had to do a 1/4" bore that was 44mm deep...
03:32 AM RyanS: adjustable reamer?
03:32 AM miss0r: RyanS: Its a matter of taste. I personally don't like'em
03:32 AM gloops: yes, avoid where possible
03:33 AM fragalot: adjustable reamers are more to allow for regrinding & adjusting back to spec.. imho.
03:33 AM miss0r: but it should be fairly easy to get yer' hands on a 23mm reamer
03:34 AM gloops: a reamer is like - i put this down it and it will be right - or it should be
03:35 AM miss0r: gloops: if your predrill/bore is sized correctly. and you are using the correct oil
03:35 AM fragalot: and feedrate
03:35 AM miss0r: yeah
03:35 AM miss0r: or you could just wing it :]
03:36 AM fragalot: constant feed pressure seems to work alright
03:37 AM miss0r: indeed
03:39 AM RyanS: $84 for a Chinese reamer...
03:41 AM fragalot: i'd bore & lap it if you expect to only need it once
03:41 AM gloops: pretty expensive new
03:41 AM miss0r: I'd buy the reamer, because you never just make a bore once
03:41 AM gloops: whats the potential for turning the shaft ?
03:42 AM gloops: i.e changing this diameter?
03:42 AM miss0r: of what ? :S
03:42 AM gloops: the shaft thats going to fit this bore
03:44 AM miss0r: I don't understand: Instead of hitting the bore size, you would change the shaft?
03:46 AM gloops: well, i was always taught to do the bore first, but if the shaft can still be mounted for turning, you arent tied to a specific size reamer, et any old reamer near the size, even imperial, and turn the shaft to suit, always easier to take a thrape off the shaft than the bore
03:47 AM RyanS: I have to match the igus bushing specs
03:49 AM miss0r: sure.
03:50 AM gloops: https://www.ebay.co.uk/itm/23mm-Parallel-Reamer-HSS-by-PICKFORD-TOOL-Co/253506221763?
03:52 AM RyanS: do they loose accuracy if they are used?
03:52 AM fragalot: everything wears
03:52 AM RyanS: old
03:53 AM XXCoder: reamer is interesting, I think if end tapers with wear, just grind some more off it
03:53 AM XXCoder: cut it off
03:53 AM XXCoder: then its like new again I guess?
03:53 AM gloops: depends how much use
03:53 AM gloops: and how used
03:54 AM RyanS: it could be shagged. maybe some hack tried to sharpen, who knows
03:55 AM miss0r: RyanS: The trick is to take a worn parallel block(one you do not care much about)
03:55 AM gloops: well that says unused, for a one off thing youre really wanting to borrow or beg etc, unless its an expensive project
03:55 AM miss0r: and run it 'inside' the flute, to push the cutting edge a smidge out
03:56 AM miss0r: thats the only 'hack' I know
03:57 AM gloops: youre looking to mount a ball turning attachment? i dunno, suppose it depends on the value of the machinery, id be thinking of putting a set screw in or something, to hold the mounting, youre only trying to avoid vibration
03:58 AM gloops: i mean, its not a crankshaft thats rotating at high speed or anything
03:58 AM miss0r: but it is rotating, though
03:59 AM RyanS: anyone heard of MZG tools? this seems expensive but I guess dormer, guhring would be $300 https://www.aliexpress.com/store/product/MZG-SWRMT-Cutting-HRC50-Taper-shank-Chucking-Reamer-with-spiral-groove-type-tungsten-steel-blade-welding/3122034_32837342267.html?spm=2114.12010612/itm2home-
03:59 AM miss0r: so using screws in there will wreck the surface
04:00 AM RyanS: I think plastic bushings are a good choice, high load, low speed like 5rpm lol, cheap
04:01 AM RyanS: actually it's 180° oscillating load
04:01 AM miss0r: RyanS: Sure. Just make sure theres enough steel surrounding it to make it stiff enough, You wouldn't want it to start vibrating on you.
04:02 AM gloops: what are the steel balls for anyway?
04:03 AM RyanS: handles maybe the odd socket joint
04:06 AM gloops: not worth messing about with http://www.nvf.co.uk/hollow-ball-80mm-diameter-18-10c.html
04:08 AM RyanS: it's a cnc plasma design procrastination project
04:08 AM RyanS: https://drive.google.com/file/d/1lPKfQwhQw8vK4EWzXQSufLACQPKFwopm/view?usp=sharing
04:09 AM RyanS: the housing will be 1045 steel
04:10 AM gloops: theres a bit of lamenting here about how wrought iron people work these days - these modern welders dont know how to make a scroll or a twist or anything, they just buy the components and stick them together - theres a reason for that - the components arent worth making anymore, just buy them, someone else does it cheaper
04:13 AM RyanS: well I also want to make things like reproduction 19th century scientific instruments, or at least the decorative radius turning
04:13 AM miss0r: RyanS: I am happy to see I am not the only one using dovetails for projects like that. Well done :]
04:15 AM gloops: 19th century scintific instruments..were very labour intensive, highly polished, by hand work etc
04:16 AM RyanS: I haven't made it yet so it's a question if the 30mm dovetail cutter of ebay lasts for one tool holder lol
04:18 AM gloops: https://www.ebay.co.uk/itm/Vintage-Philip-Harris-Galvanometer-Science-Educational/173323239424?
04:18 AM gloops: charming things
04:20 AM RyanS: this is interesting https://www.youtube.com/watch?v=Xs8XZ8X1I-g looks a bit unsafe though
04:21 AM syyl: should be ok
04:21 AM syyl: watchmakers use a free sliding tool like that for years :D
04:21 AM syyl: but the idea to use it for radiuswork with a guide is quite cool
04:22 AM RyanS: gloops watch the Clickspring you tube channel, I built his gyroscope
04:22 AM XXCoder: using peg thats genius
04:22 AM RyanS: and I could cnc plasma the profile templates
04:23 AM gloops: why not cnc the lathe?
04:24 AM gloops: the only place left you are going to see someone doing that is in India
04:24 AM RyanS: maybe one day i'll make a mini cnc lathe
04:25 AM XXCoder: RyanS: as well as make it Brother type 5 axis
04:25 AM RyanS: doing what
04:25 AM XXCoder: it works as klathe also
04:25 AM XXCoder: it can spin 5th axis that fast
04:25 AM RyanS: picture?
04:25 AM XXCoder: ill do bit better a second
04:26 AM XXCoder: https://www.youtube.com/watch?v=2TUoPDvS3WE
04:26 AM XXCoder: see, its a lathe, its a mill
04:26 AM RyanS: but can linuxCNC do 5axis?
04:26 AM XXCoder: iirc it can do 26
04:26 AM XXCoder: or possibly more? but way more than 5 thjats for sure.
04:27 AM gloops: thats actually probably the best format for 5 axis ive seen
04:27 AM XXCoder: gloops: theres some limitionms though
04:27 AM XXCoder: it cant use a tailstock
04:27 AM XXCoder: but its pretty great yeah
04:27 AM gloops: yeah, it is contained there
04:27 AM RyanS: i don't think fusion 360 does 5 axis
04:28 AM gloops: nope, no 5 axis CAM cheap
04:28 AM syyl: fusion ultimate can do 5axis
04:29 AM RyanS: wait for a affordable waterjet pump and convert plasma table
04:29 AM syyl: meh
04:29 AM syyl: i was very psyched for the small waterjet machine
04:29 AM syyl: waser?
04:29 AM syyl: but then i realised
04:30 AM syyl: i can have quite a lot of parts water or lasercut for that money
04:30 AM syyl: and dont have such a dirty machine in my shop
04:31 AM XXCoder: your brain probably can do 5 axis
04:31 AM XXCoder: slow and time-expensive though
04:31 AM syyl: 4 axis positional is kinda ok to do by hand
04:31 AM syyl: and some 4 axis simultanious too
04:32 AM gloops: i cant see open source 5 axis cam arriving anytime soon
04:32 AM gloops: unless maybe Blender does it
04:32 AM gloops: look at freecad - still not got 3 axis right
04:32 AM syyl: the problem with opensource cam systems is
04:33 AM syyl: they suck :D
04:33 AM syyl: srysly
04:33 AM syyl: and i guess they will suck for a long time
04:34 AM RyanS: that brother 5 axis would need a pretty big structure for a diy
04:34 AM syyl: for a very small work envelope
04:34 AM syyl: :(
04:35 AM RyanS: I don't know if I want to convert my BF30 to cnc
04:36 AM syyl: once a month i consider converting my rf45
04:36 AM syyl: but meh
04:36 AM syyl: i like to have a manual mill in the shop
04:37 AM RyanS: you have to change the motor because bf30 only does 3000rpm
04:37 AM syyl: that would be fine for me
04:38 AM RyanS: I don't think a cnc would speed things up I do 1 offs'
04:38 AM RyanS: but for aluminum it's slow
04:39 AM RyanS: and I can't imagine a converted bf30 being that accurate
04:41 AM syyl: cnc for one offs is brilliant :D
04:42 AM syyl: (thats what i do at work)
04:42 AM RyanS: but I got the bf30 because it's a popular one for conversion and ISO 30 spindle
04:43 AM RyanS: is it ok to quasi-manual machine with an MPG?
04:45 AM RyanS: because I'm reluctant to have only cnc
04:49 AM gloops: well, i thought about this with my lathe, maybe you could turn the screws with pulleys/belts for cnc, but leave the manual handles on, to revert back to manual - slip the belts off
04:49 AM gloops: lathe is ok to drive by leadscrews for cnc though, mill might be different
04:49 AM miss0r: my maho only does oneofs
04:49 AM miss0r: Unless the odd job comes along and I do perhaps 10
04:49 AM miss0r: but anymore than that, I tell them I am not interrested
04:49 AM syyl: i find working with an mpg very annoying
04:49 AM miss0r: mpg?
04:49 AM RyanS: how come? not leadscrew mill
04:49 AM syyl: i programm simple one offs directly on the machine
04:49 AM syyl: or do them in the MDI
04:49 AM syyl: electronic handwheel, miss0r
04:49 AM gloops: cnc mill will be working in both directions
04:49 AM syyl: in fact, we got rid of all the mpgs on the cnc machines
04:50 AM syyl: will the maho buffer all the steps and continue to move?
04:50 AM miss0r: I don't know if it buffers 'all' of the - I have not actualy counted. but it does continue
04:50 AM syyl: hrhr
04:50 AM syyl: thats a good way to crash
04:51 AM syyl: our old deckel fp4nc did that too
04:51 AM RyanS: I still don't get why cnc lathe can thread but manual needs compound at 27.5° specifically
04:51 AM miss0r: Yeah... I made a slot 4.5mm longer than I intented while cleaning up my drillpress table *sigh*
04:51 AM syyl: you dont, RyanS
04:51 AM syyl: but the 27,5° is one method
04:51 AM RyanS: don't what
04:51 AM syyl: you dont need to swing over the compound
04:52 AM syyl: i thread entirly without a compound on the lathe
04:52 AM syyl: just straight infeed
04:52 AM miss0r: its a good idea if your don't have a realy rigid compound
04:52 AM syyl: the 27,5° is about half the thread-angle (Whats that for imp. threads, 55°?)
04:53 AM syyl: that way the threading tool feeds in along one flank of the thread
04:53 AM RyanS: I thought it was to give clearance to cut the thead
04:53 AM RyanS: thread
04:53 AM syyl: and you cut only on one side of the tool
04:53 AM miss0r: makes for less stress on the cross slide/compound
04:53 AM syyl: straight infeed will produce two chips that could jam up against each other
04:54 AM syyl: a cnc lathe can (depending on the threading strategy) just do a slight movement to the side when advancing the tool in
04:54 AM RyanS: yeah so doesn't no compound cause problems >?
04:54 AM syyl: no
04:54 AM syyl: :D
04:54 AM syyl: not for me
04:54 AM syyl: i machine mostly steel/toolsteel
04:54 AM miss0r: I don't suppose you do alot of tapered work? :)
04:55 AM gloops: unless cutting acme threads
04:55 AM syyl: yes gloops
04:55 AM syyl: and very coarse threads
04:55 AM syyl: but for pitches up to 2.5mm i am fine
04:55 AM syyl: never had problems
04:55 AM syyl: i pulled the compound off the machine over a year ago
04:56 AM syyl: and never went back once :D
04:56 AM miss0r: I was out fixing a lathe last week. They did 430x10 thread manually... Now that was a sight for sore eyes
04:56 AM syyl: :D
04:56 AM syyl: http://gtwr.de/shop/pro_mykrodreh/dro/cover.jpg
04:56 AM RyanS: what about 30mm ish 18tpi? too fine?
04:57 AM miss0r: too fine for what ? :D
04:57 AM syyl: to be cut without a swung over compound?
04:57 AM syyl: nope, no problem
04:57 AM miss0r: syyl: what about tapered work? You never do any of that on the lathe?
04:57 AM RyanS: no compound
04:58 AM syyl: form tools as far as possible
04:58 AM syyl: or offset center in the tailstock
04:58 AM miss0r: sure.. but turning a iso40 tool holder is alot of work without it
04:58 AM syyl: oh, for precision tapers its another thing
04:58 AM syyl: i will just rough it out on the lathe
04:58 AM syyl: and then grind it
04:59 AM miss0r: indeed
04:59 AM syyl: https://youtu.be/EOatg0W6sV0
04:59 AM syyl: M28x1 fine thread <3
04:59 AM miss0r: did that 'singing' show up on the surface of your thread?
04:59 AM syyl: this was actually a customer part. 3 large finethread setscrews
05:00 AM RyanS: I just watched your video on toolpost grinder build
05:00 AM syyl: nope miss0r
05:00 AM miss0r: Sweet :]
05:01 AM miss0r: I could in here all day smalltalking. I need to get back to writing the code for my EDM
05:02 AM RyanS: wait, is that your video syyl?
05:02 AM syyl: yeah
05:02 AM syyl: guess so ;)
05:02 AM RyanS: i want that magnetic chuck
05:06 AM RyanS: btw the 'line boring' setup, does the between center boring bar need to be ground tool stock?
05:10 AM syyl: nope
05:10 AM syyl: it can be a rusty piece of rebar
05:10 AM syyl: b)
05:10 AM syyl: does not matter
05:10 AM syyl: have to run
05:10 AM syyl: bye
05:37 AM miss0r: this EDM code it turning out to be a little more complicated than enticipated :D
05:38 AM jthornton: morning
05:38 AM miss0r: mornin jthornton
05:40 AM XXCoder: hey
05:43 AM jthornton: what's up today?
05:43 AM miss0r: my brain is boiling trying to hack together some software for my edm controller
05:44 AM miss0r: I should realy take my work into the basement, and sit at a computer, instead of standing here in the shop for this
07:00 AM IchGucksLive: hi all
07:00 AM IchGucksLive: miss0r, edm is some way mixing things
07:00 AM IchGucksLive: most is G91
07:01 AM IchGucksLive: miss0r, is it a agie mix up
07:01 AM miss0r: Hehe. well, this is a completely home brew edition. It does not use G-code. At the moment I am programming an arduino to act as the brain box
07:01 AM IchGucksLive: ok
07:02 AM IchGucksLive: i know 4 numbers code then 6munbers x y
07:03 AM miss0r: At the moment I am looking at 500ish lines of "c" code
07:04 AM IchGucksLive: it is getting the second day thunder event here clouds pluming up getting darker by the minute
07:04 AM miss0r: I want it to automatically detect short circuit and retract fast, move fast close to the point of the short circuit and continue its doings
07:04 AM miss0r: We havent seen a drop of rain here for almost 4 weeks
07:04 AM miss0r: that combined with 25-30 degrees
07:05 AM miss0r: But we should get a little rain tonight, looking forward to that
07:05 AM IchGucksLive: miss0r, does the mashine not got a Auto short brek mode
07:05 AM XXCoder: we had sudden rain here today
07:05 AM miss0r: IchGucksLive: it does when I've build it
07:05 AM miss0r: IchGucksLive: This is a scratch build
07:06 AM IchGucksLive: XXCoder, thunder around the clar lake may be a horrable expiiance with noice going back and forth
07:06 AM IchGucksLive: miss0r, hope is always around
07:06 AM miss0r: ;)
07:06 AM unterhausen: there is a hurricane headed towards Mexico, we'll probably see a lot of rain in a week
07:06 AM IchGucksLive: im off backing up people organaicing return from forest
07:06 AM IchGucksLive: OFF
07:47 AM Loetmichel: miss0r: time to paint the lawn green to avoid fines from city and HOA?
07:48 AM miss0r: hehe, something like that
07:48 AM Loetmichel: (city for wasting water and HOA for having a brown lawn) ;)
07:48 AM miss0r: Even the mos part has become brown
07:48 AM Loetmichel: saw that predicament last year on youtube, thought it was hillarious
07:48 AM miss0r: Noone cares about that around here though
07:49 AM Loetmichel: IIRC it was somwhere in california
07:49 AM miss0r: 'some' areas has some regulations regarding the state of the lawn. but thats not exactly my neighborhood
07:49 AM miss0r: hehe, funny americans :D
07:49 AM Loetmichel: you couldnt water the lawn because of droguht regulations of the city, which didnt stop the HOA guys to fine you for having a brown lawn
07:51 AM miss0r: bureaucracy at its finest
07:52 AM Loetmichel: IMHO things like HOA are an absolute no-go when buying a house. That wouldnt fly even here in germany... closest we have here to that is with gardening communitys (most living spaces here are rented and have no garden, so there are some plots in every neighborhood where you can garden for fun, 100s of little parcels fenced in and organized as a "club"
07:55 AM miss0r: yeah. Sounds like Denmark. Some areas have an 'area plan', that determins the colours allowed on peoples roofs ect. I suppose some of those communities have some regulations regarding the lawn
07:56 AM Loetmichel: miss0r: those area plans are state driven things though
07:56 AM Loetmichel: or city issued
07:56 AM Loetmichel: not a private "company" that makes the rules for your house.
07:56 AM Loetmichel: THATS the part that would now fly with germans.
07:57 AM miss0r: :]
07:57 AM Loetmichel: we have those area plans, too
08:05 AM miss0r: damnit.. This code is breaking my brain here :D
08:17 AM jthornton: I can't even get a simple vismach to work :(
09:26 AM jthornton: firefox needs to be renamed crashalot
09:28 AM Tom_L: what's up today?
09:29 AM Tom_L: jthornton, did andy use it on his carousel demo?
09:34 AM Tom_L: can't seem to locate his demo atm
09:36 AM JT-Shop: Tom_L: there are several sims with vismach
09:37 AM JT-Shop: I can get the tk window to show up with the model and everything is connected in hal but no movement
09:42 AM Tom_L: i tried his once a long time ago and it worked ok
09:42 AM Tom_L: earth shook just now
09:51 AM * JT-Shop just realized I'm missing two studs for the surround...
09:52 AM JT-Shop: yea the sims work ok but I can't roll my own because the documents are missing some vital key
10:23 AM gloops: well thats my little rotten exhaust welding treat done
10:23 AM gloops: '20 minute job' 3 hours later...
10:24 AM miss0r: hehe. welding rusted out panels & exhausts...
10:24 AM miss0r: You have a needle prick hole, and end up a golfball size hole...
10:25 AM gloops: yep, rust doesnt weld very well
10:28 AM gloops: i thought id burned through the pipe - id actually burned through a flake that had parted from the pipe, it was several layers of rust and paper thin metal lol, ahh well, will keep them going a while longer
10:30 AM emc_ is now known as JT-Shop-2
10:30 AM JT-Shop-2: and my week job is into week 4...
10:31 AM * JT-Shop-2 just noticed the 1x4's from Menards are made in New Zealand...
10:32 AM gloops: still on with the bathroom JT-Shop?
10:37 AM JT-Shop-2: yup
10:38 AM JT-Shop-2: just figured out I'm missing 2 studs for the surround lol

11:53 AM IchGucksLive: 130 srokes last 5 min
11:53 AM IchGucksLive: im on generator power
11:54 AM IchGucksLive: Loetmichel, can give you some water as rain pures down for hr's
11:56 AM IchGucksLive: im off rescuing some stuck people in forest safty cottage as they may have made it there
11:56 AM IchGucksLive: only looking at ligning main direction
11:57 AM IchGucksLive: flowing towards france
12:04 PM gloops: ?
12:22 PM fragalot: ello
12:25 PM fragalot: miss0r: how's the EDM going?
12:25 PM miss0r: fragalot: There you are ! :D
03:47 PM JT-Shop: geez it's only quarter past 3 and I done with the shower for today I think
03:47 PM JT-Shop: off to more fun projects...
03:57 PM Tom_L: whippin yer arse?
03:58 PM JT-Shop: just a pain in my ass lol, had to add two more boards to screw the back panel to... I missed that in the instructions
03:58 PM JT-Shop: just need to let the surround adhesive cure on the back panel and I should be able to put the other two panels up tomorrow
03:59 PM Tom_L: got the water plumbed to it yet?
03:59 PM Tom_L: or just the drain
04:01 PM Tom_L: i had to change fixtures in one here and cheated by using some PEX instead of the copper it had before
04:01 PM Tom_L: too tight a space to try and solder it all up again
04:03 PM JT-Shop-2: plumbing is all done, I had cpvc so I stuck with that
04:18 PM Rab: Somebody went above and beyond in packing these sanding belts: https://i.imgur.com/3iismEQ.jpg
04:21 PM gloops: i bet whoever does the wrapping loves a sanding belt order
04:25 PM XXCoder: pretty creative
04:38 PM JT-Shop-2: yea the DusKolector works and is very quiet
04:45 PM Deejay: gn8
04:49 PM gloops: looking at a pair of m542 drivers, looks like theyre the bottom of the price list for 60v drivers
04:51 PM gloops: to upgrade the motors requires - motors, drivers, psu, bigger belts and pulleys
04:51 PM gloops: false economy trying to get away with small stuff from the start
04:52 PM JT-Shop: yep
05:01 PM miss0r: I've been coding for 16 hours straight now... The EDM is still doing some small stuff it isn't supposed to...
05:01 PM miss0r: "I'm going slightly mad"
05:02 PM kanzure_ is now known as kanzure
05:07 PM JT-Shop-2: I hate when that happens
05:08 PM JT-Shop-2: all right the cleanout door latch is repaired now for some fresh gaskets
05:32 PM miss0r: One thing it is doing it is not supposed to.. well not doing to be exact...
05:33 PM miss0r: I figured out it was not a programming issue, I simply fried my RC servo :]
05:33 PM miss0r: I just ordered 2 new ones
05:37 PM jthornton: what does the RC servo do?
05:51 PM miss0r: It rotates the spindle
05:57 PM XXCoder: the spindle itself or tool attached to it?
06:11 PM miss0r: spindle itself
06:11 PM miss0r: I'll have one last cigarette now. then i'll head off to bed. This is going nowhere tonight
06:11 PM XXCoder: as other axis?
06:12 PM miss0r: I have a geared stepper to run the z-axis ballscrew. Then I have an RC servo(continous rotation) to drive the spindle
06:12 PM miss0r: This is annoying AF....
06:13 PM miss0r: And its only 259 lines of code, and it is kicking my ass. I've lost the overview
06:13 PM XXCoder: yeah sometimes youre too close to problem
06:13 PM XXCoder: relax, sleep, come to it with fresh mind
06:13 PM miss0r: problem(s)
06:14 PM miss0r: like: when the spindle makes a direct short circuit, it needs to back off to the first point of sparking, moveback to short circuit location - 0.05mm
06:15 PM miss0r: For some reason it just jogs alot further than it should, making a new short circuit & repeating the process... just trying to push further and further below z0
06:15 PM miss0r: that and other annoying issues
06:16 PM miss0r: lol... one step is 0,00048828125 movement :D
06:16 PM miss0r: anyway. if I have the time, I will revisit it tomorrow. goodnight
06:17 PM XXCoder: night :)
