01:17 AM XXCoder: gloops: check out this one https://www.youtube.com/watch?v=vZLlUsqXzE8
01:21 AM XXCoder: hes insane!
01:21 AM XXCoder: he made a distallery out of cow pourer thing and tubes
01:21 AM XXCoder: probably #1 hardest knife he made
01:21 AM XXCoder: out of syrofoam
03:04 AM Deejay: moin
04:49 AM jthornton: morning
04:51 AM XXCoder: hey
04:52 AM XXCoder: jthornton: check the crazyness https://www.youtube.com/watch?v=vZLlUsqXzE8
05:13 AM jthornton: people do anything to make a video lol
05:13 AM XXCoder: hes been making knives out of strange materials
05:13 AM XXCoder: but that material... well it may be strangest yet. and strongest.
05:14 AM jthornton: wow it's 52Â°F outside
05:49 AM Tom_L: morning
05:50 AM Tom_L: 49°F

07:00 AM Loetmichel: maaan... EMI engineer frelancer just called... "i have a private PC that is full. 248 of 249gb used on C:... i cant find it, can you help me? ... so i used teamviewer to delete the contents of his windows/temp drawer... 178 gb free... i would have thought an EE could do that himself. Sometimes... And i am NOT the IT guy here, just the production manager :-)
12:09 PM fragalot: 'sup
12:47 PM Jymmm: nuttin much
12:52 PM fragalot: Jymmm: how are your nipples? did they survive the frost?
12:53 PM Jymmm: Nope, nippless now
12:53 PM fragalot: ouch
12:58 PM fragalot: Jymmm: if you needed a nice straight hole, 20mm +/- 0.03mm deep, diameter 3.00 + 0.02 - 0.00 in stainless, WWYD?
12:58 PM fragalot: concentric to the outside of the part, with a smaller 1.5mm through-hole at the end of this bore
12:59 PM fragalot: all with square corners (radius under 0.05mm)
12:59 PM Jymmm: fragalot: Honeslty that's above my paygrade, sorry =(
12:59 PM fragalot: same here, lol
01:00 PM fragalot: it's too small for boring bars, there are too many for EDM, and i'm not sure if only drilling & reaming would give me the concentricity needed over that length
01:04 PM Jymmm: fragalot: whats it for?
01:04 PM fragalot: sliding surface in a solenoid actuator
01:05 PM Jymmm: For a solenoid?! That's sounds like WAY too much work/effort for just a solenoid
01:05 PM fragalot: it's not "just a solenoid" though
01:06 PM Jymmm: elaborate
01:06 PM fragalot: can't really share too many details, but this one acts very fast with difficult liquids & with nearly instananeous on/off flow transitions
01:07 PM Jymmm: No solenoid I've ever seen is THAT critical, there's always give and fudge room
01:09 PM fragalot: there is some fudge room, in the total stackup there is a tolerance of 0.09mm
01:09 PM fragalot: and that already causes a 15% deviation in the process it's used in
01:10 PM Jymmm: is the solenoid being used directly or indirectly?
01:10 PM fragalot: directly, around 250 times per second
01:10 PM Jymmm: wouldn't indirectly allow for some leadway, you know, levers and shit ;)
01:11 PM fragalot: that'd interfere with the "nearly instananeous on/off flow transition" part :D
01:11 PM fragalot: we have some of those too, but they're slower
01:11 PM Jymmm: Well, you're screwed, have a nice day ;)
01:11 PM fragalot: :D
01:11 PM fragalot: it's currently being produced with custom tooling, i'm just looking for alternatives
01:20 PM sensille: how would you approach making a part like this in aluminum? https://a360.co/2TXIfq5
01:20 PM sensille: the model is for a printed part
01:20 PM sensille: split it in 2?
01:20 PM fragalot: either make it in 2 parts & bolt together, or make out of a solid billet
01:20 PM fragalot: depends on your requirements
01:21 PM fragalot: (and capabilities)
01:24 PM sensille: it's a bit big to mill it from one block, and the strength requirement aren't that big, only has to compete with a printed part (and exceed it of course)
01:24 PM fragalot: 2 parts bolted or welded it is.
01:25 PM fragalot: you could use the printed part to cast it in aluminium if you wanted to get fancy
01:25 PM sensille: i don't :)
01:25 PM sensille: just basic functional
01:26 PM sensille: 2 bolts, from the left, make the smaller part from 4mm alu, the bigger body from 8 or 10mm
01:27 PM sensille: and bolt with M4
01:27 PM sensille: and omit that support between the two. does that sound reasonable?
01:28 PM fragalot: depending on the allowable amount of flex, that would work
01:29 PM sensille: or would you add some fancy dovetail-like connections between the two? no idea what to choose, though
01:30 PM fragalot: nah, it's more a matter of selecting the right size of bolts & picking which part bolts to what
01:30 PM fragalot: for all I know this is a bracket to mount a static LED light, in which case it doesn't matter what you do
01:31 PM sensille: mount for the moving bed of a 3d printer
01:31 PM fragalot: should be alright then, the forces aren't THAT high
01:31 PM sensille: ok, thanks
01:33 PM gloops: not sure how big that is, cut the bulk of the waste out with saw or shaper
01:34 PM fragalot: waste of alu if it's not required though
01:34 PM gloops: waste of time involved as well, which costs more?
01:35 PM fragalot: 2 pieces will cost less in terms of time too
01:35 PM sensille: what waste? just the holes?
01:35 PM sensille: making it one part is not an option
01:36 PM methods_: why not?
01:36 PM methods_: how thick is that?
01:36 PM gloops: sensille im talking about starting with a block and cutting the big lumps out with a saw
01:36 PM methods_: ah 8mm thick
01:36 PM gloops: i dunno, suppose it depends on the function, bolting might be a bit dodgy
01:37 PM sensille: i don't have such a big block, and the z height of my maschine might be barely enough
01:37 PM gloops: tig welder?
01:37 PM sensille: nope
01:38 PM sensille: maybe bolting + glue
01:38 PM fragalot: just bolting will do fine
01:38 PM sensille: if that adds any strength
01:38 PM sensille: i think so also
01:40 PM sensille: if i want to bolt an m4 from the side, how thick should the piece be? 6mm sounds a bit tight, but are 8mm enough?
01:40 PM fragalot: even 6 would be alright
01:41 PM sensille: oh, good, then i'll go with that
02:12 PM FinboySlick: OK boys and girls! Let's play 'Who's that regulator?" https://i.imgur.com/BxqnC8c.jpg
02:13 PM fragalot: lol
02:13 PM fragalot: good luck
02:13 PM FinboySlick: Hint: It's 5v and won't survive 12v.
02:14 PM FinboySlick: Yeah. I'm sort of bummed out by it.
02:14 PM FinboySlick: I really liked that little router.
02:35 PM Tom_L: fragalot farm the SS job out to somebody you hate
02:35 PM fragalot: Tom_L: That's not an option :-)
02:36 PM Tom_L: how are you currently doing it?
02:36 PM fragalot: FinboySlick: I had a quick look at all of the usual suspects that I know of and I could not find any regulator in that package with that pinout
02:36 PM fragalot: Tom_L: miniature gun drill & custom reamer
02:36 PM Tom_L: so why change the process now?
02:37 PM fragalot: I don't like the custom reamer
02:37 PM fragalot: :P
02:37 PM Tom_L: you don't like the reamer or the cost of it?
02:37 PM fragalot: it's more a case of "this is how we've been doing it for 15 years" why no see if there's a new method available today
02:37 PM Tom_L: get a reverse flute reamer
02:38 PM Tom_L: that's what they do on gun barrels
02:38 PM Tom_L: i have a 10mm one if you need a pic
02:38 PM fragalot: sure
02:38 PM Tom_L: you would...
02:38 PM Tom_L: hang on.
02:39 PM fragalot: =D
02:39 PM fragalot: you offered!
02:42 PM fragalot: FinboySlick: do you know what the input & output voltage ranges are for that chip? because I've just noticed that inductor on the left side of the picture... I hadn't looked at switchers yet
02:42 PM FinboySlick: fragalot: Yeah. The 4 VIN at the top are a mystery to me too. There's always a ground among those pins.
02:43 PM FinboySlick: fragalot: Well, it fees an atheros SOC if I recall properly so it's probably got 3.3v output on one side and 5v on the other. Takes 5v input.
02:43 PM FinboySlick: (I'm guessing it outputs 5v to feed that USB port at the top)
02:44 PM fragalot: if it takes 5V how can it output 5V
02:44 PM FinboySlick: Though that might not be connected to the regulator at all, come to think of it. Maybe they throw the 5v input straight into the USB pin.
02:44 PM fragalot: yea
02:45 PM Tom_L: 2 other random reamers too: http://tom-itx.no-ip.biz:81/~webpage/cnc/thread_mills/Reamers.jpg
02:45 PM Tom_L: reverse is in the middle
02:45 PM fragalot: i've never seen a reamer like the one on the bottom
02:45 PM Tom_L: pretty common
02:46 PM FinboySlick: fragalot: Here's the bigger picture: https://wikidevi.com/w/images/f/f4/AirRouter-1.JPG
02:47 PM Tom_L: the regular spiral flute reamers will be more common than the reverse flute one
02:47 PM fragalot: i've only ever seen straight & reverse, personally
02:48 PM Tom_L: worth a shot if you can find one
02:48 PM fragalot: doesn't solve the sharp corner at the end of the hole
02:48 PM Tom_L: now you're just gettin picky
02:48 PM fragalot: :D
02:49 PM FinboySlick: fragalot: I suggest EDM and a lot of trial and error.
02:49 PM fragalot: :-)
02:51 PM Tom_L: meh, just drill it all the way thru then weld a plate to the bottom :D
02:51 PM fragalot: I give up on that regulator
02:51 PM fragalot: just replace it with a small daughter board with a known type :D
02:52 PM FinboySlick: fragalot: Yeah. I think it's a trash bin case anyway. The device isn't worth the repair, it's just that you can't buy 'em anymore.
02:52 PM FinboySlick: I have a good idea why they don't make them now though. Way too easy to brick it.
02:53 PM FinboySlick: This is a customer-facing thing. If the plug fits the hole, someone's going to put it in.
02:53 PM fragalot: :D
02:53 PM fragalot: I'm always baffled what manages to get released to the consumer market
02:53 PM FinboySlick: Sheep in New Zealand are well aware of that concept, sadly.
02:53 PM fragalot: VS what we release towards industry
02:54 PM fragalot: run it over with a truck, apply 240Vac instead of the expected 24Vdc,.. shit just deals with it & moves on
02:54 PM FinboySlick: If it can't survive a super-common 12v adapter with the same plug at the end, use a larger/smaller pin.
02:55 PM FinboySlick: At least something to give the user a chance to figure out he's doing something stupid.
02:56 PM gloops: and you didnt keep the receipt...
02:56 PM FinboySlick: heck, I'd have been fine with a 5V label next to the plug, not on the other side of the device.
02:56 PM fragalot: ._.
02:56 PM fragalot: meanwhile you've put that 12V on the USB port on it too because of their little jumper resistor
02:56 PM FinboySlick: There was nothing in it.
02:57 PM FinboySlick: But yeah. I can see a customer using this to network a printer or share a hard drive ruining two devices for the price of one booboo.
02:58 PM FinboySlick: gloops: It was just 50 bucks and no longer available. The sweet spot of being upset about it but not worth doing anything to fix it.
03:00 PM Tom_L: assholes. signed up for auto pay and they send me a late notice
03:00 PM Tom_L: and
03:00 PM Tom_L: i just opened the account
03:01 PM fragalot: ._.
03:01 PM XXCoder: what the heck
03:01 PM Tom_L: i see what sort of relationship this is gonna be...
03:02 PM fragalot: the one-off one?
03:03 PM Tom_L: took 4 days to open the account... you think i'd learn
03:03 PM Tom_L: it's a miracle large companies stay in business
03:03 PM fragalot: yea
03:04 PM fragalot: i'm still dealing with UPS requesting I pay the same import fee 3 times since january
03:04 PM fragalot: paid at the desk, got an invoice & asked what that was about, and was told it was just for my records as it'd been paid
03:04 PM fragalot: followed by a late notice
03:04 PM fragalot: so I complained, no response
03:04 PM fragalot: paid it just in case they'd add a late fee
03:04 PM fragalot: received a secondary late fee a week after that
03:05 PM fragalot: still no response after 4 complaints
03:05 PM FinboySlick: fragalot: about that sharp cornered reamed hole though. Tom might have been joking but depending on the material and part, going through and then pressing a plug at the other end might work.
03:05 PM fragalot: FinboySlick: it would need to get welded in afterwards as that part takes a beating
03:05 PM fragalot: and i'm trying to reduce the amount of post-processing
03:06 PM FinboySlick: fragalot: If you ream it smooth enough and jam it in hard enough, friction weld!
03:07 PM fragalot: hehe
03:07 PM Tom_L: half heartedly joking yes but i've seen things like that done
03:07 PM fragalot: it used to be done like that 10 or so years ago
03:07 PM FinboySlick: Too deep to bore?
03:08 PM fragalot: but the stackup tolerance with pressed or friction welded parts are too big
03:08 PM Tom_L: 3mm x 20
03:08 PM fragalot: FinboySlick: 20mm deep, 3mm dia
03:08 PM fragalot: if you know of a tiny boring bar that fits, i'm all ears :D
03:08 PM XXCoder: fragalot: one of reasons im against monopoly. no competition means they dont care. If big company that's not a monopoly already have big problems, monopoly would be much worse.
03:09 PM FinboySlick: fragalot: Stefan will grind you one ;)
03:09 PM Tom_L: http://www.mitsubishicarbide.com/application/files/7214/4643/8970/b042g.pdf
03:09 PM Tom_L: fragalot
03:09 PM fragalot: XXCoder: agreed
03:09 PM Tom_L: didn't check for sizes...
03:09 PM fragalot: FinboySlick: :D
03:09 PM fragalot: Tom_L: I did, they don't have anything usable
03:09 PM Tom_L: micro mini
03:09 PM Tom_L: yeah 3.2mm
03:10 PM Tom_L: micro mini twin... 2.2mm
03:11 PM fragalot: not long enough
03:11 PM Tom_L: i see you've been there already :D
03:11 PM fragalot: 20mm stickout for a tiny 2.5mm tool is also quite ridiculous :P
03:11 PM Tom_L: so true
03:11 PM gregcnc: PH Horn?
03:12 PM FinboySlick: Back to EDM drilling...
03:12 PM XXCoder: HH Porn
03:12 PM gregcnc: no?
03:13 PM fragalot: gregcnc: thanks - I was looking for the name of the company that made those.. i've got a few but the names' worn off of them :P
03:15 PM gregcnc: over there simtek as well
03:16 PM fragalot: horn has a few that 'l fit
03:16 PM fragalot: thanks!
03:17 PM gregcnc: horn is good stuff
03:18 PM fragalot: now if you also could name a company in europe that does thermal deburring i'm all set :P
03:19 PM gregcnc: ha, no idea I had to look that up, never heard of it
03:20 PM Tom_L: just get your torch out
03:20 PM fragalot: Tom_L: :D
03:21 PM fragalot: it is quite a neat process
03:21 PM Tom_L: sounds like it
03:30 PM gregcnc: what are scroll air compressor tip seals made of that they cost >1kUSD? https://youtu.be/R6MgiY0EYR4?t=72
03:30 PM fragalot: money
03:32 PM XXCoder: they recycle 90% of your money into seals
03:35 PM SpeedEvil: graphite made from pyrolised seal blubber.
03:35 PM XXCoder: purified, mind. need 10 seals to make one drop of it.
03:37 PM fragalot: SpeedEvil: covered with a single layer of graphene
03:45 PM Connor: I'm trying to find a replacement brush for my bandsaw.. looks like this.. https://www.baileigh.com/media/catalog/product/cache/13/thumbnail/600x/9df78eab33525d08d6e5fb8d27136e95/b/s/bs712m-guide.jpg
03:45 PM Connor: I found ones that are round.. (and spin) but.. not that style.. any ideas?
03:46 PM fragalot: that looks exactly like what stratasys used on their dimension printers
03:53 PM Rab: Connor, can you hack up an off-the-shelf wire brush?
03:54 PM Connor: It looked more dense that most. Maybe convert it to the rotary type.. I can't believe these aren't available.
03:56 PM Rab: This person went the DIY route: https://www.hobby-machinist.com/threads/4x6-bandsaw-chip-brush-and-bearings.71174/
03:57 PM Rab: Maybe the rotating brushes are so much better, they dominate the field.
03:58 PM Rab: A stationary brush seems like it could wear the blade, and wouldn't stay effective very long.
03:59 PM Connor: 2 types of rotating too.. rotates with the blade.. or rotates under power 90 degrees from the blade to knock the chips off.
04:01 PM fragalot: are there types that use bellows to clean the blade?
04:03 PM Connor: not that I've seen
05:26 PM Deejay: gn8
05:27 PM panpanpan: Hey CNC'ers!
05:28 PM panpanpan: I have a question for someone who is used to machining (semi-high-speed-milling) steel, using magnetic chucks.
05:30 PM panpanpan: We're currently, and for the past 3 years, using a magnetic table mainly designer for grinding.
05:31 PM panpanpan: We're looking to move into a stronger neodymium magnet, electro-permanent.
05:31 PM panpanpan: I have a few questions about the induction blocks one would place on top.
05:51 PM andypugh: He didnâ€™t stay around for long
05:51 PM andypugh: Not that I had anything to say.
06:11 PM jthornton: yea like what no answer in 30 seconds everyone must be dead...
06:19 PM Tom_L: he must be used to instantgram
06:19 PM jthornton: lol
06:19 PM Tom_L: how's the weather over there?
06:19 PM Tom_L: fairly nice day here
06:21 PM Tom_L: dgarr must not show up here that often
06:33 PM jthornton: I think he uses stealth mode :)
06:35 PM Tom_L: wanted to thank him for helping me with 2.8 the other day but he's hard to find
06:39 PM jthornton: yea, he knows a lot about linuxcnc
06:40 PM Tom_L: i had some remap code in the config and didn't realize it was a different python version
06:40 PM Tom_L: i would have hunted a long time for that
06:41 PM Tom_L: 2.8 still has a minor issue on the tool change
06:42 PM Tom_L: or rather 'run from here'
06:51 PM andypugh: Yes. I have not looked at that.
06:53 PM mozmck: I had major issues with run from here even in 2.7 when using a subroutine with a probe call.
06:53 PM Tom_L: most ppl using 2.8 must be using single tool files or it would have surfaced
06:56 PM Jymmm: Tom_L: When I create cam files, there's one for each tool -shug-
07:38 PM andypugh: Tom_L: https://youtu.be/pecpe49BYZs
07:41 PM _unreal_: any one do much compiling?
07:41 PM andypugh: A bit
07:41 PM _unreal_: kernel compiling?
07:41 PM andypugh: I have been known to
07:42 PM _unreal_: trying to figure out how to compile a RT kernel
07:42 PM _unreal_: https://docs.armbian.com/Developer-Guide_Build-Preparation/
07:42 PM _unreal_: I have this setup on a tower
07:42 PM andypugh: OK
07:42 PM _unreal_: its currently doing a kernel build "practice for me"
07:42 PM Tom_L: andypugh i wonder what i'm doing different
07:42 PM andypugh: Tom_L: What LinuxCNC version?
07:42 PM Tom_L: 2.8
07:42 PM andypugh: Tool change remap?
07:43 PM skunkworks: 4k laptop... I may have to get reading glasses... http://electronicsam.com/images/KandT/testing/primus/Fusion4k.png
07:43 PM Tom_L: umm... maybe
07:43 PM _unreal_: I'm not sure how close to done it is but I want to build a RT version because the kernel is for the computer I'm planing on running linuxcnc on
07:43 PM andypugh: Try your code in axis/sim_mm like I did and see what happens?
07:43 PM Tom_L: k
07:43 PM _unreal_: ok just poped up with a men for options
07:44 PM _unreal_: kernel configuration
07:44 PM andypugh: skunkworks: You can probably increase the text size while keeping all the pixels.
07:44 PM _unreal_: linux/arm 4.19.32 kernel configuration
07:44 PM andypugh: OK
07:44 PM andypugh: Blue screen, white writing?
07:44 PM _unreal_: more or less
07:44 PM Tom_L: andypugh, there's the config: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/NEW_MILL_2.8/
07:45 PM Tom_L: may not have that 'near' code fixed in that one but that's it
07:45 PM Tom_L: one line uncommented.
07:45 PM _unreal_: options like virtualizing, general architecture-dependt options, enable loadable module support,
07:45 PM andypugh: You do have a remap.
07:45 PM _unreal_: and on
07:45 PM andypugh: That might be the difference
07:45 PM _unreal_: My MAIN goal is realtime
07:45 PM _unreal_: I just dont know what it would be listed under? if even in these options
07:46 PM andypugh: _unreal_: Have you applied the preempt-rt patch?
07:46 PM _unreal_: likely not
07:46 PM skunkworks: andypugh: yes - I have not been very good at playing with themes and such
07:46 PM _unreal_: https://docs.armbian.com/Developer-Guide_Build-Preparation/
07:46 PM _unreal_: I have followed this guide just to get setup
07:46 PM _unreal_: https://www.armbian.com/tinkerboard/
07:46 PM _unreal_: for this
07:46 PM andypugh: It is in â€śkernel featuresâ€ť I think
07:47 PM panpanpan: Hey guys, i asked in here before, about 3 hours ago, but does anyone have experience using electro-permanent magnetic chucks?
07:47 PM panpanpan: got disconnected at the time
07:48 PM panpanpan: I'm having a few questions about the pole-extensions / the blocks you put on top of them
07:48 PM _unreal_: I dont see anything that says realtime or RT
07:50 PM andypugh: Do you see â€śPreemptible Kernelâ€ť
07:50 PM _unreal_: no
07:50 PM andypugh: _unreal_: What do you see, where are you?
07:50 PM andypugh: panpanpan: I have only ever used old-school mag chucks
07:51 PM _unreal_: nothing no options stating prempt
07:51 PM andypugh: (You are talking specifically about rare-earth magnets?)
07:51 PM andypugh: _unreal_: What options _do_ you see?
07:52 PM * Jymmm prefers rare Mars Magnets
07:52 PM _unreal_: to late I hit exit expeting to go back and menu and now its out of the options and doing more compiling?
07:52 PM _unreal_: I believe I need to do a RT patch regardless
07:52 PM _unreal_: but its compiling again not sure for how long
07:53 PM andypugh: _unreal_: I think so
07:53 PM _unreal_: I just dont know how
07:53 PM _unreal_: I have no background in doing this stuff so its all first time air for me
07:54 PM skunkworks: custom dpi setting of 144 is way better..
07:54 PM panpanpan: andypugh: we're currently using whats probably an old-school magnetic chuck, designed for grinding and low-force operations.
07:54 PM andypugh: Have you considered vacuum?
07:54 PM panpanpan: We use put 2 pins in the old-school magnet and workpiece, and we can mill at a high-speed rate
07:55 PM panpanpan: but, we're looking into neodymium magnets, pretty rare earth things i suppose, but the blocks they put on top confuse me
07:56 PM andypugh: Are they different to the usual ones?
07:56 PM panpanpan: the ones with grey stripe, yellow stripe, grey stripe? yes
07:56 PM panpanpan: very much
07:56 PM andypugh: Iron/brass/iron/brass
07:57 PM panpanpan: yep
07:57 PM panpanpan: i thought is was copper
07:57 PM panpanpan: :)
07:57 PM andypugh: Depends on the manufacturer. possibly
07:57 PM andypugh: So, the ones for the rare-earch chuck are different?
07:57 PM panpanpan: the neodymium ones are 5 times stronger, or so i've read
07:57 PM panpanpan: and seem to be mainly a different design
07:58 PM panpanpan: i find them in the striped-edition but never for milling purpose, only for grinding
07:58 PM panpanpan: https://proxy.duckduckgo.com/iu/?u=http%3A%2F%2Fwww.industrydepot.com%2Fimages%2Feepm01.jpg&f=1
07:58 PM gregcnc: almost nobody mills on mag chucks
07:58 PM _unreal_: mag chuck?
07:58 PM panpanpan: magnetic chuck
07:59 PM panpanpan: we do gregcnc, pretty fast too. But only works if we're able to put 2 pints through the workpiece and mag chuck
07:59 PM andypugh: The stripes are to prevent the block bridging (and shorting) the magentic circuit. In the picture you show the blocks are exactly on the poles, so are not bridging
08:00 PM panpanpan: that way we fix X and Y movement, and the magnet takes care of Z movement
08:00 PM Elmo40: 2 pints? of a good stout?
08:00 PM gregcnc: most parts don't have convenient location pins
08:00 PM panpanpan: ic, so, i'll always need to keep the blocks as-is
08:01 PM panpanpan: i'm lucky, gregcnc
08:01 PM panpanpan: :)
08:01 PM andypugh: I can imagine that a laser-cut aluminium sheet would work nicely.
08:01 PM panpanpan: andypugh, i was hoping to replace the 20 blocks on the poles by one big sheet of steel
08:01 PM andypugh: panpanpan: The laminated blocks might work on that chuck. Try them.
08:02 PM andypugh: I mean a plate cut to the exact part outline.
08:03 PM panpanpan: so, one big massive plate instead of the 20 tiny blocks is a big no?
08:03 PM _unreal_: how long does a kernel typically take to compile?
08:03 PM panpanpan: because of shorting of magnetic flux or whatever magnets do :)
08:04 PM Rab: _unreal_, depends on the machine compiling. In the '90s it could take an hour.
08:04 PM andypugh: panpanpan: Yes. But an aluminum/brass outline mechanically fixed would work.
08:05 PM _unreal_: dual core 1.8ghz
08:05 PM _unreal_: intel 2gb ram
08:05 PM gregcnc: those chucks are different
08:05 PM panpanpan: alright, thanks for the info andypugh
08:05 PM _unreal_: err intel core 2
08:05 PM andypugh: Or a steel plate (to get a good hold) with a hole in the middle to expose poles for the part.
08:06 PM andypugh: panpanpan: I hope it is obvious that I am making his up from having a Physics degree and having used a mag chuck a few times. I am not any sort of expert.
08:07 PM panpanpan: maybe the best move would be to keep using the old-school design, but with neodymium magnets, and mill my position-holes in that magnet like we do now.
08:08 PM panpanpan: yeah, having a physics degree means you know about magnets and magnetic flux and what not
08:08 PM panpanpan: what you're sayings makes sense after what i've read on google, and i feared it would be like that
08:09 PM andypugh: I would hesitate to mill a mag chuck in case I found magnets (or in the case of the one you had a picture of, touch the electrical coils)
08:09 PM panpanpan: done it before and do it quite often
08:10 PM panpanpan: now for cleaning purposes mainly, every 2 months i flatten the surface to make it flat again
08:10 PM andypugh: I guess you are working for money and have a budget for new chucks :-)
08:10 PM panpanpan: its my first one :) still going after 3 years!
08:10 PM andypugh: (But grinding the top flat is normal)
08:10 PM Tom_L: andypugh i can't seem to get the config to copy over
08:10 PM Tom_L: sim that is
08:11 PM andypugh: Canâ€™t you just open it from the config picker?
08:11 PM Tom_L: i'll have to move my tool table etc
08:11 PM andypugh: Just edit the sim tool table, You only have to add a dummy tool 32
08:12 PM Tom_L: how do you run from the picker?
08:12 PM Tom_L: it still asks me to save the file or quit
08:12 PM _unreal_: simple Tom_L run like hell
08:13 PM andypugh: It asks if you want to copy the config across to where you can edit it. Say yes
08:13 PM _unreal_: sigh wish there was a status bar on this compiling
08:14 PM andypugh: _unreal_: Are you entering the command â€śmake menuconfigâ€ť at any point?
08:14 PM Tom_L: yeah, then nothing happens
08:14 PM _unreal_: no idea if I have 5min left or an hour left
08:14 PM andypugh: _unreal_: Press Ctrl-C to stop it?
08:14 PM _unreal_: I still see lots of drivers flying by drm_encoder_slave.o for example
08:14 PM _unreal_: lots of .o's going by :)
08:15 PM _unreal_: I'd rather just let it finish
08:15 PM _unreal_: if I kill it and it requires some file clean up I dont know what to clean up
08:15 PM Tom_L: andypugh how do you create a yt of your screen?
08:16 PM andypugh: Ah, well, In my case I was running in a VM on my Mac and Quicktime Player includes a screen recorder
08:16 PM Tom_L: mmm
08:17 PM flyback: wait
08:17 PM flyback: quicktime player for windows?
08:17 PM Tom_L: i suppose i can't do that in linux
08:17 PM _unreal_: I use to have a mac. just an older power pc laptop
08:17 PM andypugh: flyback: QT player for Mac
08:17 PM flyback: oh ok
08:17 PM flyback: uninstall quicktime player fro windows
08:17 PM andypugh: There are Linux screen recorders
08:17 PM flyback: IT'S CANUCKED
08:17 PM flyback: remote exploit and apple is not supporting it
08:17 PM flyback: oh are you blind?
08:18 PM flyback: nm
08:18 PM flyback: thought it said screen readers
08:18 PM Tom_L: you're canuck'd
08:21 PM Tom_L: andypugh, REMAP=M6 modalgroup=6 prolog=change_prolog ngc=change epilog=change_epilog
08:21 PM Tom_L: is in the config
08:21 PM andypugh: Yes, I noticed
08:21 PM andypugh: But not in the sim config?
08:21 PM Tom_L: i doubt it but i can't get sim to work
08:22 PM andypugh: Well, thatâ€™s wierd
08:22 PM andypugh: Try commenting out the remap and see what happens?
08:22 PM Tom_L: i could comment it out as i'm not using it now but still...
08:22 PM Tom_L: i'll go out and try it both ways again...
08:24 PM panpanpan: Cya, fellow machinists! And thanks for info andypugh
08:25 PM andypugh: Bye
08:29 PM Tom_L: andypugh, commenting out that line took care of it
08:30 PM andypugh: OK, so this appears to be a remap bug
08:30 PM Tom_L: so it's something in remap
08:30 PM Tom_L: yeah, it didn't do that in 2.7
08:32 PM Tom_L: should i add that to the bug report?
08:32 PM andypugh: Yes
08:34 PM Tom_L: k
08:35 PM flyback: https://www.youtube.com/watch?v=KYYxLiW85Vs
08:40 PM _unreal_: omg its stil compiling
08:41 PM andypugh: It might take severla hours
08:42 PM andypugh: If it isnâ€™t doing what you want then donâ€™t let it carry on doing it
08:44 PM _unreal_: but I must go on....
08:44 PM _unreal_: I dont even know what its doing :)
08:44 PM Tom_L: it's gonna be slow compiling on an arm
08:45 PM _unreal_: i'm not compiling on arm. I'm on an intel machine
08:45 PM Tom_L: still takes a while
08:46 PM andypugh: OK, time to cease
08:46 PM _unreal_: yep 100% both cores
09:00 PM flyback: this is why I setup a esxi box
09:00 PM flyback: for compiling shit
09:00 PM flyback: even though it was slower I could just start it and let it run in the background
09:00 PM flyback: undisturbed
09:00 PM flyback: sadly that hw died long ago
09:09 PM Elmo40: anyone use those 3D printer boards for router CNC tables?
09:10 PM Elmo40: they have many driver options. pushing almost 2A stepper motors.
09:10 PM Elmo40: and upwards of 6 drivers. could be used for a robot :-)
09:12 PM Elmo40: i've heard people using GRBL firmware. i haven't tried it yet. problem is you still need the brains (PC) connected to it. would LinuxCNC be those brains?
09:14 PM Tom_L: unlikely
09:24 PM _unreal_: yay it finished
09:25 PM _unreal_: never mind didnt finish
09:26 PM Tom_L: this has just been a drill, everyone stand down and go back to work...
09:26 PM _unreal_: building DEB's now
09:26 PM _unreal_: I walked into the room and the fans were silent..
09:26 PM _unreal_: so i was like finally
09:26 PM _unreal_: NOPE
09:27 PM _unreal_: now it finished
09:27 PM _unreal_: 120min
09:45 PM Elmo40: Tom_L, still a drill? or real deal now?
09:45 PM Tom_L: huh?
09:45 PM Tom_L: oh
09:45 PM Tom_L: :)
09:46 PM Tom_L: was trying to figure out my remap issue
09:48 PM Jymmm: Tom_L: <-- GO THAT WAY -->
09:48 PM Tom_L: phew! thanks
09:48 PM Jymmm: =)
09:49 PM Tom_L: i bet it started due to the multi spindle support now
09:49 PM Tom_L: it's above my pay grade to try and fix it though
09:49 PM Tom_L: i just get paid to complain
09:49 PM _unreal_: god most of the linux rooms are getting to be really sad. nothing but ass holes in them.... ask a question and get nothing but WISE ASS bs responces
09:50 PM Jymmm: Tom_L: You just need a Flux Galvometer Self Sealing Stem Bolt
09:50 PM _unreal_: or a flux capacitor
09:50 PM Jymmm: _unreal_: Nah, those are SOOOO 80's
09:51 PM _unreal_: true
09:51 PM Tom_L: yeah, i thought it reached it's half life long ago
09:54 PM Jymmm: Did someone say half life??? CESIUM-137 FTW... http://unitednuclear.com/index.php?main_page=product_info&cPath=2_5&products_id=819
09:58 PM Elmo40: those faulty flux capacitors...
10:02 PM Connor: Anyone know where to get a set of ware blocks for my gauge blocks?
10:18 PM Tom_L: not sure what you're looking for
10:19 PM Tom_L: oh non certified blocks
10:21 PM Tom_L: Connor you want a whole set?
10:22 PM Tom_L: i got a couple gage blocks from the local lab and told them i didn't need cert
