12:01 AM `Wolf: chuck in question https://i.imgur.com/ckwi5Uo.jpg https://i.imgur.com/EhH5hSG.jpg
12:04 AM `Wolf: no data plate either
12:04 AM CaptHindsight: they went out of business years ago
12:04 AM `Wolf: that I know lol
12:04 AM CaptHindsight: http://www.practicalmachinist.com/vb/general-archive/what-happened-ralmikes-tool-rama-83310/
12:05 AM `Wolf: whole lot of stuff here with Ralmikes tags lol
12:06 AM `Wolf: and I suddenly have a bunch of tools that I have never used before lol
12:07 AM CaptHindsight: http://www.practicalmachinist.com/vb/general-archive/ralmikes-tool-rama-still-around-92152/
12:08 AM CaptHindsight: I believe County Supply swallowed up Ralmikes.
12:08 AM CaptHindsight: Ralmike's Tool-A-Rama, Inc.
12:08 AM CaptHindsight: 524 Lincoln Boulevard
12:08 AM CaptHindsight: Middlesex, NJ 08846 USA
12:10 AM CaptHindsight: I bought a lathe earlier this year that sat in storage for decades
12:10 AM CaptHindsight: they knew they were going to store it so it was coated in wax
12:10 AM MarcelineVQ: wellp, if you're fancying a trip there's http://collections.si.edu/search/results.htm?q=Ralmike's+Tool-A-Rama
12:11 AM `Wolf: yeah I found that
12:11 AM `Wolf: thats in DC right? lol
12:11 AM MarcelineVQ: idk hehe
12:12 AM MarcelineVQ: what kind of stats are you after on it?
12:13 AM `Wolf: how the thing works lol
12:13 AM MarcelineVQ: pop her open :>
12:13 AM `Wolf: thing has too many bolts on it lol
12:14 AM MarcelineVQ: wonder if the center ones are standoffs
12:14 AM CaptHindsight: in the drawers were https://imagebin.ca/v/3kP4pvKCbQrz original rusty cans of way lube
12:14 AM MarcelineVQ: made from real whales
12:14 AM `Wolf: thats cool =)
12:14 AM CaptHindsight: likely :)
12:15 AM `Wolf: this lot has some new in packaging black and decker annular cutters lol
12:16 AM CaptHindsight: I once got a bridgeport form an old machinist
12:16 AM CaptHindsight: he offered me a box of tooling for $100, so I said sure
12:17 AM CaptHindsight: when I got home it was filled with cat40 holders, 4" face mills, 2" face mills on and on
12:19 AM CaptHindsight: `Wolf: auction?
12:19 AM `Wolf: high school g/f’s father
12:20 AM CaptHindsight: late for me, bbl
12:20 AM `Wolf: half of this stuff was purchased new in the late 80’s
12:29 AM MarcelineVQ: archivist: that driver from the other day https://imagebin.ca/v/3kP9F79b3pg7 molten diodes are to/from PSU
12:32 AM the_wench: Heinz: archivist said best to stay in channel so the german speakers can spot you and your question
12:59 AM IchGucksLive: hi
01:01 AM IchGucksLive: heinz: noch da
01:22 AM monkeyisl: https://youtu.be/2m1-rD_DnzI?t=144 <--- could i do this by lcnc?
01:24 AM IchGucksLive: yes
01:24 AM IchGucksLive: 5 Axis Kinetics
01:25 AM IchGucksLive: monkeyisl: see the robot sim
01:26 AM Wolf__: it can do all of that * (some coding and assembly may be required)
01:26 AM IchGucksLive: monkeyisl: if you dont want to go that hard the 4axis makes pretty good ones
01:26 AM archivist: MarcelineVQ, a bit odd for those to go, supposed to protect the driver from reverse connection
01:27 AM IchGucksLive: monkeyisl: look at my sculpter 4A https://www.youtube.com/watch?v=sqx9w80diKo
01:28 AM archivist: depends what you are making whether you need kins or not
01:30 AM IchGucksLive: archivist you can do alot without
01:30 AM IchGucksLive: thats the best
01:31 AM IchGucksLive: monkeyisl: in vismach is a 5Axis includet to test
01:33 AM dave__ is now known as gloops
01:33 AM IchGucksLive: gloops: shuffel a freeway
01:34 AM IchGucksLive: as sky news reports brekdown
01:34 AM IchGucksLive: heinz: letzter versuch sonst wieder um 19 uhr
01:35 AM IchGucksLive: way free is not like freeway ;-(
01:37 AM IchGucksLive: till later :P
01:38 AM gloops: https://www.facebook.com/photo.php?fbid=10210979184139492&set=pcb.1792685587449838&type=3&theater
01:38 AM gloops: bloke making his own timing pulleys
01:39 AM archivist: facefuck, must log in to continue.....
01:40 AM archivist: a closed shop to sell you crap
01:40 AM gloops: looks like hes grinding them
01:40 AM gloops: ahh no milling
01:41 AM archivist: timing pulleys should be hobbed
01:41 AM gloops: he ground a cutter first
01:41 AM gloops: cutting with horizontal spindle + dividing head
01:45 AM Wolf__: there is a name for that… =)
01:45 AM archivist: milling
01:46 AM archivist: no crumpets error, standby breakfast cheeeeeese on toast
01:46 AM Wolf__: horizontal mill + dividing head would be mobbing or i’m I thinking wrong
01:47 AM archivist: milling, unless it is a universal with table set to helix of the hob and a hob geared to rotary
01:48 AM gloops: see you should get on these facebook groups archivist, youd be a legend overnight
01:49 AM gloops: i think you would say you were hobbing gears with that setup though lol
01:51 AM archivist: eff oooorf getting on facefuck
01:52 AM gloops: install ubuntu - mint
01:52 AM archivist: I did a linuxcnc hobbing setup for JS on his victoria mill
01:53 AM archivist: the late JS
01:53 AM Deejay: moin
01:55 AM gloops: that reminds me, i need to order belts
01:56 AM gloops: i just know im going to get this thing almost finished then get stuck by the holiday post with some bit i forgot
01:58 AM gloops: have shelved rotating nut plan due to time, will add extra bearings to ballscrew in an attempt to increase critical speed to 1500 rpm plus
01:58 AM Wolf__: so, how crazy of a idea would it be to attempt to install a disk brake on a 1236 sized lathe
01:58 AM archivist: I should think of something for an xmas project
01:59 AM MarcelineVQ: brass clipon bowties
01:59 AM archivist: last xmas was playing fartuinos
02:02 AM gloops: Wolf how about a disc brake off a bicycle
02:02 AM gloops: small, easy fitting, theyre pretty strong
02:04 AM Wolf__: I was thinking 200mm motorcycle disk
02:05 AM Wolf__: I guess I could give a mountain bike disk brake a shot
02:05 AM Wolf__: but I’m somewhat doubtful that it would work well
02:07 AM gloops: no idea really, ive looked at bicycle discs with a similar idea myself, they have got some stopping power, bring 15 stone to a halt pretty quick doing 20mph, how that compares to the momentum on a lathe no idea
02:08 AM archivist: some do have brakes, should work
02:08 AM Wolf__: I have a spare set of cable op bike disks
02:09 AM archivist: can be better on the motor not direct on the spindle
02:10 AM Wolf__: that would make it slightly simpler i think
02:10 AM gloops: combined with clutch would be great
02:10 AM archivist: reason for the brake says motor/spindle
02:11 AM gloops: could have a foot bar running the length of the lathe
02:12 AM Wolf__: lazy way would be 3 phase motor + vfd w/ braking
02:12 AM Wolf__: gloops: thats the idea, adding brake like the larger lathes have
02:13 AM Wolf__: though disk might be overkill, just simple friction band would probably do
02:13 AM archivist: for fast stopping on the motor, for milling parts on the spindle
02:14 AM Wolf__: faster stopping is the idea
02:16 AM archivist: motor inertia is multiplied by any reduction gearing
02:17 AM jesseg: hey have you guys ever heard of any such thing as an electronic phase converter which was made to use like 3 phase -- i.e. a product that would generate 3 phase and allow you to use your mill or lathe's regular direction control switches -- and allow multiple machines to be running off one phase converter?
02:18 AM jesseg: one that was exactly usable as a rotary phase converter, but was solid state..
02:18 AM Wolf__: first part, yes, multiple I dont know about
02:18 AM jesseg: Seems with these modern VFD's you're supposed to wire them one to a machine, and start/stop with the VFD not the machine's switch
02:18 AM Wolf__: phase-o-matic
02:19 AM jesseg: Are they just capacitor network boxes, or actual 3 phase converters?
02:19 AM archivist: jesseg, trouble with vfd's is they dont like their output switched and they are measuring the back emf
02:20 AM Wolf__: no idea whats in the box
02:20 AM Wolf__: I’ll know in about 3 days
02:20 AM archivist: toy ones are capacitors, real ones are motors
02:20 AM jesseg: archivist, gotcha. or motors with capacitors :P
02:21 AM Wolf__: mill i’m picking up has one, docs do suggest using it to make a rotatory converter to get rated HP
02:21 AM jesseg: yeah
02:21 AM archivist: without a motor alternator they go out of balance
02:21 AM jesseg: because with the capacitor trick, you're basically actually only feeding power to one of the 3 coils, and a fraction of the power to the other two, hence the reduced HP.
02:24 AM jesseg: I'm kind of envisioning basically a true sine inverter that just happens to put out 3 phase..
02:24 AM Wolf__: plus side is craigslist around here is full of cheap 3 phase motors
02:24 AM archivist: very expensive
02:26 AM jesseg: archivist, wouldn't have to be very expensive if it was mass produced. Inverter technology is not exactly new :D
02:26 AM archivist: because of the cost it becomes simpler and better to use separate for each machine
02:27 AM MarcelineVQ: Wolf__: huh, they are too, what's with that
02:27 AM jesseg: yeah, and of course VFD's don't put put pure sine - they put out chopped sine, which is why the motors whine
02:28 AM archivist: part of that chopping is measuring the motor
02:28 AM jesseg: Could I use a 3HP motor as a rotary phase converter for another 3HP motor? lol
02:28 AM archivist: never had one whine here
02:28 AM jesseg: archivist, yeah, kind of hard on the windings though I guess
02:29 AM jesseg: better VFDs may chop at a higher (ultra sonic) frequency, in which case the high frequency vibration is still there but you can't hear it
02:29 AM archivist: 3hp is getting to the limits of domestic power
02:30 AM jesseg: What?!
02:30 AM jesseg: a 30A 240v breaker can deliver like 12 electrical HP
02:30 AM jesseg: 40A I mean
02:31 AM jesseg: Breakers to most homes is like 100-200A isn't it?
02:31 AM archivist: we only get 60 total for the entire house here
02:31 AM MarcelineVQ: for the main in, not for the wires in your wall <_<
02:32 AM archivist: outlets are 13A
02:32 AM jesseg: archivist, MarcelineVQ a common water heater is 4500 watts -- that's 6 electrical HP
02:32 AM Wolf__: that has to suck, I have 50A and 100A sub out on my home panel
02:32 AM jesseg: A common electric forced air furnace is like 15-20kw, which is like 20-26HP
02:33 AM archivist: buggers reduced my incoming fuse rating
02:33 AM archivist: people use gas not electricity for main heating here
02:33 AM MarcelineVQ: idk how common common is, my hw heater is on a 15 amp breaker
02:34 AM jesseg: MarcelineVQ, lol that's kind of surprising if it's a 4500w heater
02:34 AM MarcelineVQ: well it wouldn't be, that's kind of what I'm getting at
02:34 AM Wolf__: try tankless electric hot water heater lol 3x 40A breakers iirc
02:34 AM jesseg: archivist, what country are you in? I'm comparing things to USA norms, could be different in other countries
02:34 AM archivist: UK
02:36 AM jesseg: archivist, ok gotcha. But even there, is 15A @ 240v (3 motor HP) really getting to the limits of domestic power?
02:36 AM Wolf__: my mom’s neighbor’s mini mansion has 400A incoming electrical service…
02:36 AM archivist: I wonder why electrical fires are more common over there :)
02:36 AM Wolf__: fucking nuts
02:36 AM MarcelineVQ: UK at least has the advantage of 220 single line :(
02:37 AM archivist: jesseg, 13A sockets
02:39 AM jesseg: archivist, ohhhhhh, gotcha, just saying that 3hp is pushing the limits of a standard wall socket.. gotcha.. yeah, our standard wall sockets in USA are 15A @ 120v, so only 2.4 electrical HP.. But we have bigger plugs for kitchen oven/stove, clothes drier, and they are generally 240v/30A to 50A depending..
02:40 AM jesseg: so in a home you look around, most of the wall sockets are 120v/15A.. But in a spot where the kitchen range goes or the clothes drier or whatever, there will be a big 30A+ socket with 240v on it.
02:40 AM jesseg: We put those in to run things like mills and lathes as well.
02:41 AM archivist: here there is a pair of spurs for cooker and shower/hot water but only 30A
02:41 AM Wolf__: hmm,I wonder if tesla makes a power wall thing w/ 3 phase out lol
02:42 AM archivist: its the load switching that inverters wont like unless loads of protection added
02:43 AM jesseg: archivist, oh, 30A at 240v would run a 5HP motor just fine, especially if it was on a VFD with soft start
02:44 AM archivist: also ask your provider for 3 phase
02:45 AM jesseg: yeah.... but I envision that costing a whole lot
02:46 AM jesseg: actually, I've already got a little 18HP 3 cylinder Mitsubishi diesel engine and a 14kw 3 phase genset end, as well as an old Quincy 5HP class dual stage air compressor... my plans are to build those to all work together, to provide shop air, 3 phase, as well as shop heat in the winter...
02:46 AM archivist: it costs a lot here too
02:46 AM jesseg: as well as backup power if mains fails.
02:47 AM jesseg: And frankly, with the cost of power, I'm seriously considering going off grid someday
02:48 AM jesseg: but we'll have to wait and see if I ever get around to any of that :P
02:50 AM jesseg: Basically, our power costs about 8 cents a KWH. Running a little diesel generator is probably around 16 cents/kwh.
02:50 AM archivist: I pay 14 pence twice your costs
02:51 AM jesseg: Of course, generator has some upkeep costs. But then again, the utility company charges quite a hansom fee for just being connected, on top of the per kwh fee.
02:51 AM jesseg: yeah, you could possibly run a diesel generator at the same cost :P
02:51 AM archivist: dont think so these days
02:52 AM jesseg: my brother and I were doing some quick math the other day to see how much cheaper the utilities would be as compared to running a diesel generator. The gap isn't as big as you think :D
02:53 AM MarcelineVQ: there's quite a bit of utility in 'always on' though
02:53 AM jesseg: archivist, What general area in the UK are you?
02:53 AM MarcelineVQ: diesel always on would require quite the battery bank I'd think
02:54 AM jesseg: MarcelineVQ, true -- so yeah an ideal off grid situation would involve quite a bit of solar as well to bring up the efficiency. But by relying on solar for times during the day when your power consumption wasn't so great, you could definitely increase your average cost efficiency
02:54 AM archivist: the low tax red diesel seems a bit pricey these days
02:54 AM jesseg: yeah it's more expensive than gasoline here
02:55 AM MarcelineVQ: solar is finally getting material improvements at least
02:55 AM archivist: I have a diesel 3 phase genset but the noise and it is a bit too big
02:55 AM jesseg: archivist, yeah, I'm thinking of building that stuff all into a different building, so I don't have to listen to it. A little power house shed :P
02:55 AM archivist: it used to cost us about £11 a day to run it at the museum
02:56 AM jesseg: how many kw?
02:57 AM archivist: was not measuring output but it is a straight 6 engine
02:57 AM jesseg: Ahhh yeah that's gonna slurp down a bit of fuel :D
02:57 AM archivist: capable of 50 kva
02:57 AM jesseg: okay yeah
02:59 AM archivist: I resored it this year to sell now has output meters
02:59 AM jesseg: cool
02:59 AM jesseg: what brand is it?
03:00 AM archivist: Morrison locally made http://www.collection.archivist.info/archive/DJCPD/PD/2017/2017_07_23_Morrison/IMG_2573.JPG
03:00 AM archivist: was running a bit slow there
03:02 AM jesseg: that's pretty nice!
03:02 AM archivist: was in a state http://www.collection.archivist.info/archive/DJCPD/PD/2017/2017_06_10_Morrison_generator_panel/IMG_2563.JPG
03:02 AM archivist: holes rotted through the base of the panel
03:04 AM jesseg: wow you did a lot of work
03:05 AM archivist: the meters had died too
03:05 AM archivist: http://www.collection.archivist.info/searchv13.php?searchstr=pd+morrison
03:18 AM jesseg: haha yeah that one is kind of too big
03:18 AM jesseg: for running a lathe on :P
03:19 AM archivist: need a bigger lathe
03:19 AM jesseg: a much bigger lathe
03:20 AM archivist: was a giggle at the museum, we could switch a compressor straight on which would bin all three ammeters, it would growl a bit and carry on
03:21 AM archivist: pin all three
03:23 AM jesseg: LOL yup
03:23 AM jesseg: nothing quite like having all the power you need when you need it
03:26 AM archivist: i wonder how inverters can deal with the start up overload
03:26 AM jesseg: If they are designed right it should be no problem at all.
03:27 AM archivist: IF
03:27 AM jesseg: A good design has instantaneous current limiting set at safe levels..
03:27 AM archivist: dont want limiting with motor staring
03:28 AM archivist: mooooore amps
03:28 AM jesseg: well, some mills/lathes have a softstart box in there that does actually limit current to the windings by one method or another till the speed is up a bit.
03:29 AM jesseg: so I don't see a problem with the inverter limiting current to protect itself
03:29 AM archivist: star delta motors
03:29 AM jesseg: yeah sometimes they switch winding order and sometimes they switch in ballast resistors, but either way, it limits the starting current
03:30 AM archivist: we had a big star/delta at the museum, cannot remember it we ran it on the generator
03:31 AM jesseg: by "winding order" I mean configuration such that the motor, during start, is "wired" to be for a much higher voltage, essentially starting it in under voltage conditions. (I'm speaking of 3 phase stuff of course.)
03:31 AM archivist: star and delta wiring
03:31 AM jesseg: yeah
03:32 AM jesseg: although switching the wiring to a higher voltage configuration during startup would also work
03:32 AM archivist: was a manual switch on that motor
03:32 AM archivist: star is higer voltage than delta
03:33 AM jesseg: As a matter of fact, before I bought my mill, I went and looked at it at the shop that sold it to me.. They had it wired to 240v 3 phase.. I noticed the motor took sort of long time to spool up. When I got it home, I checked, and it was configured for 480v. They'd been running it for years on 240 like that lol
03:35 AM archivist: I have rewired a few motors, sometimes picking open the insulation to find the ends
03:35 AM jesseg: yeah, star essentially sort of puts the windings in series, while delta is more parallel.. sort of :P
03:59 AM archivist: been sitting in my watch list awhile https://www.ebay.co.uk/itm/3-HP-DIGITAL-240V-to-415V-3-PHASE-INVERTER-CONVERTER-LATHE-MILL-DRILL/152176133868
04:04 AM jesseg: That seems a little bit expensive for onle 3HP
04:04 AM jesseg: only
04:06 AM jesseg: I got one similar to this from China, seems to work fine: www.ebay.co.uk/itm/Updated-2-2KW-220V-3HP-10A-VFD-Variable-Frequency-Drive-Speed-Control-3-Phase-CE/142442366683
04:12 AM herbert__: Good morning everybody!
04:13 AM herbert__: Does anyone know a way to use a modern laptop for linuxcnc. Specifically any satisfying Laptot->Parallel-Port solutions?
04:13 AM herbert__: *Laptop
04:17 AM jesseg: I dunno about that
04:18 AM jesseg: I know my brother talks about all the different problems that different laptops have with running linuxcnc
04:20 AM archivist: jesseg, note that one is a double because 440 out
04:20 AM herbert__: jesseg: in general, what is the most modern hardware that I can run linuxcnc on? Like, it would be great to use a mesa card and the parallel port or sth. mini-ATX formfactor even better :)
04:21 AM archivist: laptops have a few issues that stop them being useful for cnc, power saving and slowing down is one
04:22 AM herbert__: atm we are running on a vintage ASUS A2500H oldtimer
04:22 AM archivist: jt has a list of motherboards, you can now use an ethernet connection to mesa rather than pci/parallel
04:22 AM herbert__: jeah, I messaged jt, but no response so far :=
04:23 AM herbert__: jthornton: hola?
04:23 AM archivist: still asleep
04:24 AM herbert__: archivist: there is quite a list of mesa cards. how do I know which one to chose?
04:25 AM archivist: I know, still not used one myself yet
04:29 AM jesseg: archivist, oh, yeah, I guess if your motor is 440v and cannot be configured for 220, then yeah you need a doubling VFD
04:30 AM jesseg: herbert__, I really don't know anything helpful about using laptops on linuxcnc
04:30 AM jesseg: I've only used it in desktops
04:30 AM herbert__: jesseg: can you name your mainboard? I am just looking for references to do research on...
04:30 AM archivist: jesseg, I have a dual speed motor on one lathe that falls in that category
04:31 AM jesseg: archivist, Ahhhh, gotcha... configurable for poles but not configurable for voltage :D
04:32 AM jesseg: herbert__, I actually haven't used linuxcnc in years....
04:32 AM herbert__: jesseg: I see, thanks anyway :)
04:32 AM jesseg: no problem!
04:33 AM jesseg: but I imagine most modern desktops would work
04:41 AM jthornton: herbert__: http://paste.ubuntu.com/26169314/
04:43 AM herbert__: jthornton: thanks! is it similar to the one in the linuxcnc doc? http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Latency-Test
04:44 AM jthornton: might be you would have to look
04:45 AM herbert__: k!
04:46 AM jthornton: for mesa cards you don't use the base thread
04:48 AM rene-dev: herbert__ you can use linuxcnc on a laptop, with some limitations. but forget about the parallel port. its not 1990 anymore.
04:50 AM rene-dev: if you disable all the power management, you can be ok. what always caused problems are acpi events. if you close the display, or unplug the ac adapter, you see that.
04:50 AM herbert__: rene-dev: I somehow am limited to understand how one could use linuxcnc without parallel port... I would be happy if you could enlighten me :)
04:50 AM rene-dev: buy a mesa 7i92. its cheap, and has the parallel port pinout.
04:51 AM jthornton: herbert__: https://mesaus.com/index.php?route=product/product&path=69&product_id=78
04:51 AM jthornton: nevermind your trying to use a laptop have fun
04:52 AM rene-dev: I would not buy the pci mesa cards, because pci is also old, and going away.
04:53 AM rene-dev: jthornton I have done it many times. its possible.
04:53 AM XXCoder: with good latency?
04:54 AM MarkusBec: with laptops it realy depends on the laptop
04:54 AM herbert__: as I said, we use an ASUS A2500H laptop that works quite well
04:54 AM jthornton: I have done a lot of things that are possible but I would not recommend them to someone new
04:54 AM MarkusBec: but with all a mesa card is required
04:55 AM XXCoder: rene-dev: possible sure. my laptop could do it.
04:55 AM XXCoder: but latency?
04:55 AM herbert__: 40000ns
04:55 AM XXCoder: not too bad
04:55 AM rene-dev: XXCoder I didnt use softstepping. latency was ok, but I cant remember the numbers. but it went thru the roof on an acpi event.
04:55 AM jthornton: run the latency test for a few hours
04:55 AM XXCoder: my lapotop it was over 100k
04:55 AM rene-dev: but the same happens on a normal pc when you unplug the power ;D
04:56 AM jthornton: latency-histogram --nobase
04:56 AM XXCoder: my 12 year old pc however only had 10k something
04:56 AM XXCoder: I set it at 15k
05:00 AM rene-dev: it always depends what you need. if you have some high dynamic servo system, or a wooden router, cutting cheese.
05:00 AM jthornton: XXCoder: took a quote for a machine to a customer yesterday and came home with a check in my pocket :)
05:00 AM XXCoder: awesome
05:00 AM XXCoder: what machine will do? or is that top secret or tme machine
05:00 AM jthornton: yea first big job in a few years
05:01 AM jthornton: just a part cleaning machine
05:01 AM jthornton: in line cleaner
05:01 AM XXCoder: nice!
05:01 AM XXCoder: I bet its awesome being machine builder
05:01 AM XXCoder: engineering
05:02 AM jthornton: yea I originally designed them back in 1998
05:02 AM jthornton: yes I love the challenge of building and designing
05:04 AM MarkusBec: XXCoder: yes old machines have no sysmanagment and powersaving witch results in good latency
05:04 AM MarkusBec: but the feeling to use it is alsow like 1990 :)
05:04 AM XXCoder: not really it runs smoothly
05:04 AM XXCoder: but then it was quite high end for early 0s
05:05 AM MarkusBec: more ram and quadcore are nice
05:05 AM MarkusBec: with it you can open firefox without freezing it :)
05:06 AM jthornton: I've never surfed the web on a CNC machine
05:06 AM XXCoder: I do but only on irc and directly related to cnc stuff
05:07 AM XXCoder: irc only when actually running a progra,
05:08 AM jthornton: I need to get my nest box installed today
05:08 AM MattyMatt: those machines felt fast enough in 1990
05:08 AM archivist: I used to run a buildbot on my cnc
05:09 AM XXCoder: UGGGH "You don't need to hear to know what these officers are saying to you"
05:09 AM XXCoder: yet another deaf person died by copos
05:10 AM MattyMatt: turn off "display window while moving" and they were Great™
05:13 AM MattyMatt: Yesterday I learned why flat belts aren't used on tools anymore. I've made an elastic band gun
05:14 AM XXCoder: hopefully everyones ok
05:14 AM MattyMatt: my back is suffering from crawling under the tablesaw to retreive the belt
05:16 AM MattyMatt: reckon I'll dig a couple of grooves in the pulleys and try O rings next
05:16 AM MattyMatt: or just give in and order a V belt now
05:18 AM MattyMatt: also lessons learned. 400W is not enough for a belt sander
05:18 AM XXCoder: woodgear wood belt sander plans?
05:19 AM MattyMatt: but hey you're mostly americans. 400W wasn't enough for the food blender I harvested it from
05:20 AM MattyMatt: yeah it turned out to be totally woodgears. I just copied the rollers at first but then I wanted his tracking mech and ended up making a full copy, except mirrored
05:23 AM XXCoder: nice
05:23 AM MattyMatt: mirrored so I could power it from a drill, until I found a proper motor
05:23 AM MattyMatt: which I never did, just a blender
05:24 AM MattyMatt: drive belt is elastic. vacuum cleaner spare
05:25 AM MattyMatt: buying a V belt will double what I've spent on this :)
05:28 AM MattyMatt: it worked long enough to tell me I need this sander. real precision woodwork at last
05:30 AM XXCoder: nice :)
05:30 AM MattyMatt: I was going to mount it vertically to do metal like a Wilton, but 400W says no
05:32 AM MattyMatt: meh, it doesn't hurt to use it gently. abrasives don't mind a light touch AFAIK
05:34 AM MattyMatt: oh yeah, motor is too hot to touch after 2 minutes. This motor has no future
05:35 AM XXCoder: too bad
05:36 AM MattyMatt: I should get some tool drawers made before it burns out
05:37 AM XXCoder: water cooled ;)
05:37 AM MattyMatt: open frame shaded pole motor in plywood box. water not allowed
05:37 AM XXCoder: lol
05:38 AM XXCoder: if you use raditior and turobine you could make motor that keeps itself cool while running
05:38 AM MattyMatt: I could put a bigger fan on the motor
05:40 AM MattyMatt: or use a vacuum cleaner and drive the sander off its own dust extractor
05:41 AM XXCoder: thats definitely possible
05:42 AM MattyMatt: meh, I need to start going to farm auctions. that's where all the cheap induction motors are at
05:42 AM XXCoder: no junkyard or electrics recycling center?
05:42 AM XXCoder: or something like habit for humanity place
05:42 AM XXCoder: tons junk electrics you can buy cheap and stri[
05:42 AM XXCoder: habitity for humanity or whatever its calleds
05:43 AM MattyMatt: trouble is UK appliances are all full of shitty motors
05:43 AM XXCoder: im sure there is million used ashitty table saws you can get motors from
05:44 AM MattyMatt: not a million. I got a nice one but most in UK will use a brushed universal motor
05:45 AM MattyMatt: I got a crappy saw with a nice 3kW motor, I should say
05:45 AM MattyMatt: sheet steel table. I doubt it was ever flat
05:45 AM XXCoder: lol
05:47 AM MattyMatt: I should go the scrapyard and ask what they've got
05:48 AM XXCoder: cool :)
05:48 AM MattyMatt: trouble is I'm right by the docks. all the scrap is either cars, or is on its way to China
05:48 AM XXCoder: if i had more skills I would try build stuff for fun
05:48 AM XXCoder: but dunno
05:48 AM XXCoder: I wonder if you could use car stuff
05:48 AM XXCoder: like starter
05:49 AM MattyMatt: not much prime industrial stuff
05:49 AM MattyMatt: or agricultural
05:49 AM MattyMatt: duty cycle is the problem there too
05:49 AM MattyMatt: they'd get hot real quick
05:49 AM MattyMatt: and I'd need a meaty 12V supply
05:49 AM XXCoder: true starter is designed to run maybe couple minutes at worse
05:50 AM XXCoder: or just 12v battery
05:50 AM XXCoder: some 12v applicatipons would last quite a while on lead 12v battery
05:51 AM MattyMatt: I might as well use a corded drill if I want hot and noisy
05:51 AM XXCoder: lol
05:52 AM MattyMatt: maybe I should mount the sander on the table saw, and share the motor
05:53 AM XXCoder: or portable motor moduole
05:53 AM MattyMatt: that's direct drive though. 14" of TCT death wheel right on the motor shaft
05:53 AM Tom_L: jthornton, you around?
05:53 AM jthornton: yup
05:54 AM Tom_L: any idea what i'm doing wrong on those welds? http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Welding/Z_Column_tack2.jpg
05:54 AM Tom_L: rust or not enough gas?
05:54 AM Tom_L: it's argon / co2 mix
05:54 AM XXCoder: wrong person dping the welds.
05:54 AM XXCoder: joking heh
05:55 AM * XXCoder is not a welder.
05:55 AM Deejay: grinder and paint make you the welder you ain't! ;)
05:55 AM Tom_L: it doesn't look hot enough to me, i'm not used to this mig yet
05:55 AM _methods: Tom_L: you sure the gas is working?
05:55 AM XXCoder: my bro probably would know but then he havent welded since middle school
05:55 AM _methods: there is a lot of porosity in the welds
05:55 AM _methods: almost looks like shield gas isn't flowing
05:55 AM Tom_L: methods, pretty sure but i'm gonna go over it all later today
05:56 AM jthornton: I'd clean the weld area to bright metal and turn up the heat a bit... don't watch the arc, watch the puddle
05:56 AM Tom_L: i sanded all the paint off with a DA
05:57 AM Tom_L: but it is old metal
05:57 AM jthornton: ok, could not tell from the photo, looked like mill scale on the angle
05:57 AM Tom_L: it probably is
05:57 AM _methods: what welder and what are your settings set at?
05:57 AM _methods: and how thick is that tubing and angle
05:57 AM Tom_L: miller 175 set above halfway on the voltage
05:58 AM Tom_L: it's close to 1/4" but not quite
05:58 AM Tom_L: other than being dirty i can't figure what's going onn
05:59 AM _methods: yeah might try slowing down the wire and bump the voltage up one
05:59 AM _methods: but check to make sure you got gas flow first
06:00 AM Tom_L: i'm used to stick and haven't used this thing enough to figure it out yet
06:00 AM jthornton: practice on some scrap
06:00 AM _methods: yeah
06:01 AM Tom_L: i have been
06:01 AM jthornton: keep the tip close so the wire stick out is short and watch the puddle
06:01 AM _methods: just spend some time watching it puddle and moving it along
06:01 AM Tom_L: that might become scrap...
06:01 AM jthornton: lol
06:01 AM Tom_L: i was about as close to the metal as you can get
06:02 AM Tom_L: it's nice and flat on the bottom though :)
06:03 AM Tom_L: spent probably an hour with a depth mic aligning it
06:03 AM Tom_L: i still plan to have it milled flat
06:04 AM _methods: when did you get the 175?
06:04 AM _methods: that's a nice machine
06:04 AM Tom_L: yeah i like it. i've had it several years but haven't used it alot
06:05 AM Tom_L: 220 v
06:05 AM _methods: yeah that machine should weld whatever you throw at it
06:05 AM Tom_L: i figured i wouldn't weld much above this thickness when i got it
06:06 AM _methods: oh it's not a millermatic 175?
06:07 AM _methods: oh i thought those things would weld thicker than that
06:11 AM jthornton: https://www.youtube.com/watch?v=ophtUI7RbmU
06:16 AM jthornton: https://www.youtube.com/watch?v=w4RrDeUKcH4
06:18 AM Tom_L: oh ick, flux core...
06:19 AM joesnuffy: aye
06:20 AM Tom_L: i'll take a good look at those later today
06:20 AM jthornton: that second link is how I weld with circles
06:21 AM Tom_L: i was doing that
06:21 AM Tom_L: only mine doesn't look quite that good :)
06:21 AM jthornton: practice
06:21 AM archivist: Tom_L, looks dirty, are you sure you have the gas through?
06:21 AM Tom_L: i'm gonna check later today
06:22 AM Tom_L: those are the 2 things that come to mind and have been suggested
06:22 AM jthornton: make sure your connections are the right way for mig
06:22 AM Tom_L: JT-Shop, i'll tack it all up and bring it over :D
06:22 AM jthornton: ok
06:22 AM Tom_L: they are
06:22 AM Tom_L: + electrode
06:23 AM Tom_L: how much gas flow should i have? iirc it's set around 20 cf/hr
06:23 AM jthornton: I've never changed mine since getting them so don't know the right way off the top of my head
06:23 AM Tom_L: i don't think i have either
06:24 AM Tom_L: i got a spool of flux core but it's still in the wrapper where it will probably stay forever
06:24 AM jthornton: lol
06:26 AM Tom_L: maybe i should take up knitting instead
06:27 AM archivist: welding takes a bit of practice
06:27 AM Tom_L: i know, i've done plenty of stick just not mig
06:27 AM archivist: took me a week or two to get the slag to curl like my instructor
06:29 AM Tom_L: it's a shame, i don't even think they teach it in school here anymore
06:29 AM archivist: after stick we were thrown onto mig
06:29 AM archivist: I went as trainee welder at a trailer maker
06:31 AM jthornton: I applied for a job at a shipyard many many years ago and after the welding test he said I could be a first class tacker or a last class welder lol
06:32 AM jthornton: I decided I didn't want to weld for a living
06:32 AM archivist: I spent a couple of years at it
06:33 AM archivist: went from steel mig to aluminium mig
06:35 AM jthornton: aluminum mig looks weird after welding steel blobs of molten metal
06:38 AM archivist: we were on piece work, I cut up some welds that looked good, no penetration
06:39 AM jthornton: I ran into that trying to plug weld a piano hinge on aluminum
06:40 AM jthornton: weld looked good but the hinge fell off due to no penetration at all
06:40 AM jthornton: had to enlarge the holes and start in the center
06:42 AM archivist: Tom_L, you may have the gas flow right but be too far away so the gas gets blown away
06:50 AM _methods: archivist: he said he had the nozzle right up on the work piece
06:54 AM jthornton: 41F at the moment with a high of 39F...
07:17 AM miss0r: I'm seriously getting no love from my CNC mill at the moment.
07:17 AM miss0r: I do believe I've gone ahead and fried the video module.
07:17 AM miss0r: But, not to worrie: A used replacement will only set me back ~700eur
07:18 AM * miss0r sobs
07:18 AM miss0r: In a manly way, mind you!
07:18 AM archivist: they do fleece users
07:20 AM archivist: miss0r, component level repair
07:21 AM miss0r: archivist: Yeah, someone who has an idea what to do might be able to get away with that - sure :]
07:22 AM miss0r: I can done 'some' repairs on electronics. But getting into this board is beyound me
07:22 AM archivist: probably has some standard video chip and could scope it signals
07:24 AM miss0r: I guess that is worth a shot. Better than spending more money than I have on a replacement.
07:25 AM miss0r: Sadly, if I should fail to repair it, it seems certain the mill will be standing still for quite a while :-/
07:25 AM anonnumberanon: how to diy steel gears, max 2 inch diameter, small teeth like maybe max 2mm long teeth
07:26 AM archivist: just tell the seller of the card you can upgrade to linuxcnc for less
07:26 AM miss0r: archivist: I'm not sure that is acurate, thou ;]
07:26 AM archivist: anonnumberanon, gear milling or hobbing and linuxcnc
07:27 AM anonnumberanon: because with the sizes of mills on a cnc i don't see how it can cut such small things
07:27 AM archivist: get a reasonable quality rotary for gear cutting
07:28 AM archivist: anonnumberanon, http://gears.archivist.info/gears/IMG_1214_hires.JPG
07:28 AM anonnumberanon: wow that's small
07:28 AM archivist: 2" is big for me
07:28 AM archivist: :)
07:29 AM miss0r: lol
07:29 AM anonnumberanon: my tiniest gear would be for a dc motor output shaft, maybe 1/2 or 2 times the diameter of that one in your pic
07:30 AM anonnumberanon: you mean i need to buy or make a rotary machine?
07:30 AM anonnumberanon: is that some sort of mini lathe?
07:30 AM archivist: http://www.archivist.info/cnc/target.php
07:31 AM archivist: you need something to index the blank one tooth
07:33 AM archivist: rotary table is left http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_03_31_contrate_gear_prototype/IMG_1206.JPG
07:33 AM archivist: http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_11_02_Drive_gear/IMG_1392.JPG
07:34 AM archivist: the vertex rotaries are reasonable for the money
07:42 AM archivist: 4 axis gear cutting early days http://www.collection.archivist.info/archive/DJCPD/PD/2008/2008_02_28_cnc/P2210001.JPG
07:43 AM archivist: Z being mandraulic at that time
07:47 AM MattyMatt: https://i.imgur.com/rhL1LmP.jpg cheapest 4th axis
07:48 AM MattyMatt: only works for factors of 200 tooth count :)
07:49 AM miss0r: archivist: sadly, scoping the output of the video board, I get both a nice'n stable horizontal and vertical sync frequenzy. When I put my scope on the 'video signal' I get som blobber, I can't make sense of, but I guess that is how its meant to look. Which could indicate its the monitor who is faulting at the moment
07:50 AM archivist: miss0r, sync off horizontal
07:50 AM archivist: sync the scope
07:50 AM miss0r: 15.9990hz
07:51 AM miss0r: khz*
07:51 AM archivist: freq ok for close to 625
07:51 AM miss0r: wha? :S
07:51 AM archivist: but video data is timed by the horizontal sync
07:52 AM MattyMatt: 15,625 = UK, 15,360 = NTSC
07:52 AM miss0r: the vertical is 49.9021hz
07:52 AM archivist: those are correct most likely
07:52 AM miss0r: archivist: so what should my video signal look like?
07:53 AM archivist: hf spikes
07:53 AM miss0r: yeah, I get that :) Should I see it pippling in at 15.9990khz?
07:54 AM archivist: no, many mhz
07:54 AM archivist: pixel could be about 6 meg ish width
07:55 AM MattyMatt: you'll see the 4.43 colour signal if it's PAL
07:55 AM archivist: if it is a plain character display of 800 ish dots horizontal
07:56 AM archivist: image I saw the other day was single colour character
07:56 AM miss0r: 2 secs, I'm uploading a photo of the screen on the scope, while trying to measure the video signal
07:57 AM miss0r: archivist: This is what I get scoping the video signal: http://picpaste.com/IMG_20171212_145512-Q0EcrKUu.jpg
07:57 AM archivist: you need a local old style TV engineer near you
07:57 AM archivist: looks reasonable for character data
07:57 AM MattyMatt: I've got an old telly here you can have. it's got ceefax
07:57 AM miss0r: Atleast its not flatlining
07:58 AM miss0r: Perhaps its something with the monitor then
07:58 AM archivist: voltage peak to peak?
07:59 AM miss0r: I can guess based on the readout, or I could go to the scope and enable it? :)
07:59 AM archivist: should be 1.4 open circuit .7v into the monitor if terminated
08:00 AM archivist: many monitors are "helpful" hand give a blank display if they dont lock up to the sync
08:01 AM miss0r: I get 540mV on the scope (took me a while to remember how to turn it on)
08:01 AM archivist: lead in connected to monitor?
08:02 AM archivist: in/is
08:02 AM miss0r: nope. floppin' in the breeze
08:02 AM miss0r: I don't like the sound of thoes numbers of yours
08:03 AM archivist: video is .7, its the law (standard)
08:03 AM miss0r: Doesn't mean I have to like it ;)
08:03 AM miss0r: So theres something wrong there then...
08:04 AM archivist: you put twice the level into the wire via a resistor and there is one as a load
08:04 AM archivist: so you see .7
08:05 AM archivist: 6845 on the graphics card?
08:05 AM miss0r: Excellent question. I'll see if I can find a picture online good enough to determin it fast. Otherwise I will go uninstall it
08:05 AM archivist: is the scope probe set to x10
08:06 AM archivist: it could be of the TTL type with 5v logic level video data
08:07 AM miss0r: hehe it was
08:07 AM archivist: 5v ttl levels then
08:07 AM archivist: set monitor correctly :)
08:08 AM miss0r: Well, it was working before and I haven't changed anything
08:08 AM archivist: or level convert for a standard level monitor
08:08 AM miss0r: So i probaly changed something without knowing :)
08:08 AM archivist: those little switches!
08:09 AM archivist: http://www.collection.archivist.info/archive/manuals/IM74_NEC_multisync/page_e_0011.jpg
08:10 AM miss0r: Funny thing is: The monitor was set for manual 'on' 'color' '8' even thou this is not color
08:11 AM archivist: when you were playing with an adapter or something
08:12 AM miss0r: no. That is the current switch setting. And I believe it was this setting when I took it out as well
08:13 AM archivist: and the ttl/analog switch?
08:14 AM miss0r: I don't have one.
08:14 AM miss0r: My monitor does not have its chasing, so i'm relying on this photo from google: https://picclick.com/Rare-1988-Nec-Multisync-Ii-Jc-1402Hma-Crt-Fully-272836924724.html#&gid=1&pid=5
08:18 AM archivist: managed to move some switch, some experimentation needed to find original setting
08:18 AM archivist: or dead monitor as you can see signals
08:18 AM miss0r: archivist: A few days ago someone posted me a link to a german version of the manual for the multisync II monitor in ##electronics but I can't seem to grap it from my history
08:19 AM miss0r: which would suck, but not as much as the video module being dead
08:19 AM miss0r: in that case I would 'just' have to figure out how to convert the signal. Which is what I was doing and ended up giving up, returning to reinstall the old screen lol
08:20 AM archivist: there are some ttl to vga circuits on the web, just a few resistors so you could try another monitor
08:20 AM miss0r: hmmm... Just with resistors you saY ? :] I HAVE resistors
08:22 AM miss0r: do you have a link for said contraption? All i can find looks a bit more complicated that just a 'few resistors'
08:23 AM archivist: stuff like https://www.repairfaq.org/sam/vidconv.htm
08:24 AM miss0r: I have to go pick up the kid. I will be back later
08:24 AM archivist: years since I was looking to bodge one up
08:24 AM miss0r: thanks so far
10:17 AM MarcelineVQ: Tom_L: ping
10:52 AM wolrah_: Good morning Linux CNC! Getting a new CNC Mill started soon.
11:07 AM wolrah_: OS: 64 bit Windows 10 Professional (Version 10.0 Build 15063)
11:09 AM archivist: we dont support windows for cnc in here
11:09 AM JT-Shop: must be using mach
11:10 AM wolrah_: XD Thanks for the heads up... I accedently clicked a menu option in AdiIRC...
11:10 AM archivist: upgrades to a working OS are available :)
11:10 AM anonnumberanon: I'm gonna have a 10-day vacation and want to prepare myself for building a cnc mill, i want to do 3 days of electronics, 3 days of family time around christmas and 3-4 days of building stuff to get better so that eventually i can make the machine. Would you recommend a course of action to make myself a crash course on metal work and etc?
11:10 AM wolrah_: Linux CNC resides on dedicated hardware.
11:10 AM anonnumberanon: (the 3 days of electronics has nothing to do with cnc stuff, just want to geek out on microcontrollers and such)
11:11 AM archivist: anonnumberanon, a manual machine to see what cutting metal is like
11:11 AM SpeedEvil: At that sort of level, you are absolutely limited to a kit.
11:11 AM SpeedEvil: IMO
11:12 AM wolrah_: Get some sheet metal and cut/fold a box. always harder than it may seem
11:12 AM anonnumberanon: wolrah_, that sounds good
11:13 AM archivist: can be the biscuit tin, just need good scissors
11:13 AM anonnumberanon: i want to make something that's absolutely perfect in measurements and tolerances since i figure this will be required for a cnc build, any mini projects for this?
11:13 AM wolrah_: what tools do you have avlable? Have a milling machine?
11:14 AM archivist: nothing is perfect, learn what tolerance means
11:14 AM anonnumberanon: no milling machine, im getting myself a drill press for christmas, already got welder, sawzall, angle grinder, hand drills
11:15 AM archivist: wolrah_, http://www.collection.archivist.info/searchv13.php?searchstr=tinware
11:15 AM anonnumberanon: dremel, but somehow it's hiding somewhere
11:15 AM wolrah_: Have a look at: https://maritime.org/doc/index.htm#train
11:16 AM wolrah_: there are quite a few publications by the military that go over basic shop procedures... this is just one source of this material
11:16 AM archivist: sheet metal books for bending
11:18 AM wolrah_: http://navybmr.com/study%20material/14250a/14250A_ch13.pdf
11:19 AM wolrah_: I am currently building the electronics/control enclosure for my CNC mill, I am using sheetmetal teqniques almost exclusively.
11:23 AM SpeedEvil: anonnumberanon: you absolutely can't do this in the timeframe. You need to find a kit if you want to.
11:23 AM SpeedEvil: Or at the very least a proven design.
11:23 AM anonnumberanon: a kit of what SpeedEvil
11:23 AM anonnumberanon: i don't want to make something in 3 days, not a machine
11:24 AM SpeedEvil: Everything. A complete kit with all the parts that you just bolt together.
11:24 AM anonnumberanon: but i want to train, really hard
11:24 AM wolrah_: anonnumberanon, I beleve there is a misunderstanding of your goals
11:24 AM anonnumberanon: probably heh
11:24 AM anonnumberanon: the milling machine is a longer term goal
11:26 AM archivist: I suppose some of my self training was getting old technical books and reading them
11:27 AM SpeedEvil: Indeed. That may be more productive.

11:28 AM SpeedEvil: as one example
11:29 AM archivist: hmm I wonder if that will fit on my nooooo to me old tablet
11:34 AM IchGucksLive: hi
11:36 AM miss0r: archivist: Back from the daily stuff with kids, dinner, ect... Now I can look at this monitor issue
11:36 AM miss0r: Hello IchGucksLive
11:37 AM IchGucksLive: :-)
11:40 AM anonnumberanon: ok so far on list: drill metal, tap metal, cut metal, measure perpendicularity and tolerances, measure metal bending from welding
11:40 AM anonnumberanon: man that book was useful :)
11:42 AM archivist: miss0r, we got as far as having signals but monitor not understanding
11:43 AM archivist: or in the wrong mode and deliberately blank or not switched on
11:43 AM miss0r: Yeah. I have the horisontal and vertical sync running. I also have something that looks like a video signal output
11:43 AM miss0r: It is switched on, That can be scratched from the list.
11:44 AM miss0r: I can turn up the "background color" to have the screen light up a bit
11:44 AM archivist: it was a regular in the workshop when looking over someones shoulder
11:44 AM miss0r: yeah, I'll bet ;)
11:45 AM archivist: some flat line on the scope....it's not working!
11:45 AM miss0r: I haven't had any luck tracking down the manual for the NEC MS II monitor, so I can't be sure about the switch positioning. All i've got to go on for switch positioning is a rear picture of what may/may not be the screen
11:45 AM miss0r: theres no flatline on the scope! :o
11:45 AM archivist: in the divide and conquer fault finding the lefthand side is running
11:46 AM archivist: exactly so fault on the right
11:47 AM miss0r: yeah
11:48 AM miss0r: Which makes me somewhat unhappy... As that monitor was my failover device :) but it also makes me happy, as the error is not pointing at something massively expensive
11:48 AM miss0r: You only had the manual for the first multisync monitor, right?
11:48 AM archivist: so what was that LCD you were messing with
11:49 AM archivist: yes only the mk1
11:49 AM miss0r: Some odball dell tft.. but I tried my luck feeding the video signal from the mill through this: https://www.ebay.co.uk/itm/Arcade-Game-RGB-CGA-EGA-YUV-to-VGA-HD-Video-Converter-Board-HD9800-GBS8200-New/272848401256?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2648
11:50 AM miss0r: (as I don't think I have a LCD that goes all the way down to 15khz)
11:50 AM miss0r: when I ordered that board, I was under the impression that the mill was EGA or CGA
11:51 AM miss0r: But I suppose it can still be used, if I convert the TTL to a lover voltage signal? assuming I have not already fried the board here
11:52 AM archivist: some of those were 5v probably
11:52 AM miss0r: In any case, I did not have any luck with that board as-is
11:53 AM archivist: the image was not that good, was it just a scan size error or missing pixels
11:53 AM archivist: missing pixels would be not getting the dot clock matched
11:54 AM miss0r: http://picpaste.com/IMG_20171209_094501-VqZhOBV4.jpg
11:54 AM dave__ is now known as gloops
11:55 AM cradek: that's a wrong sync rate by a factor of 4 or 8
11:55 AM cradek: (horizontal)
11:55 AM cradek: vertical is way off too
11:56 AM cradek: LCDs are terrible at displaying their non-native resolution, especially when hooked up to analog signals
11:56 AM archivist: did you get a paper manual for that adapter or is the ebay page all you get
11:56 AM miss0r: I have a link for one, hang on
11:56 AM cradek: is the signal ntscish?
11:57 AM archivist: hard to tell if the input or output rates are wrong
11:57 AM miss0r: https://www.mikesarcade.com/estore/datasheets/GBS-8200-booklet.pdf
11:57 AM miss0r: cradek: The video signal is 15.9khz TTL
11:57 AM archivist: his h frequency is 16khz
11:57 AM Loetmichel: *MAAAN* thats a nice feeling. Just had a telco with our designer and my boss sitting next to me. New project: enclose a 50" TFT into a steel frame/enclosure. Boss wanted to just "size up our 24" model"... then the designer and me startet to "talk metal"... "Lets do that this way..." "No not possible at that size, would bend, lets make it THAT way..." Ideas and imagined construction details
11:57 AM Loetmichel: flying thru the phone forth and back for 1.5 hours. Bosses eyes flew from the phone to me to the phone... i think at a certain point he didnt unerstood a single word we were talking. :-) ... that "FLOW" feeling.
11:58 AM archivist: that has changed since earlier :)
11:59 AM gloops: cradek - excellent work on the 4-5 axis demos btw, your knowledge may be required next year
11:59 AM miss0r: [14:49]<miss0r>15.9990hz
11:59 AM archivist: very close to 16k not pal or ntsc
12:00 PM miss0r: yeah. this is its very own puddle'of mud
12:00 PM archivist: 50hz frame
12:00 PM miss0r: which is why I was thinking that the GBS8200 board would be the way to go
12:01 PM miss0r: the LCD I have here: Horizontal Freq. Analog:30 -
12:01 PM miss0r: 83kHz (Automatic)
12:01 PM miss0r: Vertical Freq. 56 -
12:01 PM miss0r: 75Hz (Automatic)
12:01 PM archivist: the on screen setup should work first
12:01 PM miss0r: that is working
12:02 PM archivist: then when in that play to capture the input
12:02 PM archivist: cga vintage
12:03 PM miss0r: you lost me
12:03 PM miss0r: Its not CGA either. Its a monochrome output.
12:03 PM archivist: mga
12:04 PM archivist: although mga was a highres
12:04 PM miss0r: The pinout looks like mga
12:04 PM Loetmichel: what frequencies had hercules?
12:04 PM archivist: if you look the cga inputs are separate
12:05 PM miss0r: I'm using this site as a refrence: http://www.nullmodem.com/DB-9.htm
12:05 PM miss0r: Has some great stuff on there by the way
12:06 PM archivist: the cga input is not the 9 pin
12:06 PM miss0r: Loetmichel: 18.425 0.500 kHz
12:06 PM miss0r: I get the 'video signal' on pin 7
12:07 PM Loetmichel: ah, then its not hercules, either
12:07 PM Loetmichel: ;)
12:07 PM miss0r: HS 8 VS 9
12:07 PM archivist: some had inverted syncs in that era
12:07 PM miss0r: so far we have only determined this is nothing
12:08 PM archivist: there were mono cards but done seem to have docs (catalogued)
12:09 PM miss0r: feck!. Why on gods green earth would this NEC stop working on me
12:11 PM roycroft: because it's 35 years old?
12:12 PM miss0r: Its hardly even in its prime!
12:12 PM Loetmichel: hihi
12:13 PM Loetmichel: roycroft: its too young
12:13 PM Loetmichel: a Monitor fom the 60ties would still run ;)
12:15 PM miss0r: archivist: Do you have any last minut ideas for me to try, before I bend over'n start sobbin' ?
12:20 PM archivist: just been upstairs looking at a manual for old mono card for the PC, it used a 6845
12:20 PM archivist: I do have a mono monitor from the period
12:20 PM miss0r: I will go 'rip out the video module. From there we will be wiser, I hope
12:21 PM archivist: the video chips gives us the mode to emulate/configure to
12:25 PM miss0r: okay, theres 58 ICs on the board :)
12:26 PM miss0r: I'll take a photo
12:27 PM archivist: one big one?
12:27 PM archivist: or old and dirty TTL video :)
12:28 PM miss0r: 9 of them are bigger than the rest
12:28 PM miss0r: http://picpaste.com/IMG_20171212_192659-sTbjQkfc.jpg
12:29 PM miss0r: looks pretty down'n dirty to me
12:30 PM archivist: sure is, that is old school ttl do it yourself design before 6845 designs
12:31 PM miss0r: Did I mention I have no idea what to do with this information?
12:34 PM archivist: I have not seen your sync waveforms, I would look for a plain mono TV era monitor, as that works in that frequency range
12:34 PM miss0r: And the wonderfull thought of replacing any CRT monster with a flatscreen?
12:35 PM archivist: that card will almost always be repairable if one took a backup of the character roms
12:35 PM archivist: flat screens dont normally work at TV rates
12:36 PM archivist: might get away with scart input on a flat TV
12:36 PM archivist: will need to reduce the levels of the 5v to video standards though
12:37 PM * miss0r is dishartened
12:37 PM archivist: should be excited that there are possibilities
12:37 PM miss0r: Where does it leave us on the current monitor? Do you have some magic up your sleeve ?
12:37 PM archivist: my sleeve is here not in your workshop
12:39 PM miss0r: hehe. Looking at the routes on this video board something looks somewhat odd
12:40 PM miss0r: 1,2,7 & 8 are all wired together
12:40 PM miss0r: ahh... not odd at all. The only realy I have the signals I have at the screen end, must be cause the cable that was installed is special made
12:40 PM archivist: all ground?
12:41 PM miss0r: yeah
12:41 PM archivist: there may already be a composite signal
12:41 PM gloops: https://www.ebay.co.uk/itm/Vintage-1980s-IBM-5151-Computer-Monitor-Green-Monochrome-Excellent-Vry-Light-Use/282761292048? jeez asking a lot for these old monitors
12:42 PM archivist: that is what I have here, I'm rich
12:43 PM archivist: I have the computer as well but it is sick
12:43 PM gloops: ive seen the odd one on the boot sale, never bother with them, think i will now
12:44 PM archivist: "vintage"
12:44 PM miss0r: and apparently pin4 has some option to be set with two of thoes bridges/latches
12:44 PM gloops: well you probably get one of these for nothing - just finding one
12:45 PM archivist: miss0r, Im guessing it is juuuust possible there is a composite mode for plain TV monitors
12:45 PM miss0r: I don't realy have any of thoes either :)
12:46 PM archivist: goes to scart input on tv
12:46 PM archivist: to the cvbs pin
12:46 PM archivist: composite video blanking and sync
12:47 PM * miss0r does not own a TV with scart anymore. :)
12:47 PM archivist: wife may complain about the missing TV though
12:48 PM miss0r: I do believe the TV in the living room has composite inputs on the back. But She'll start a war if I tear it off the wall and run down here with it
12:48 PM archivist: scope the pin before stealing it
12:49 PM archivist: have you put the nec back and fiddled all the switches
12:51 PM miss0r: I have had it back, no, not ALL the switches
12:51 PM miss0r: I will do so in a sec. I looked at a german manual for the nec MS II the other day - browsing the history
12:52 PM miss0r: that and its something of a tast to CRAWL in there
12:57 PM IchGucksLive: im off Gn8
01:03 PM * miss0r pops the champain !
01:03 PM miss0r: archivist: Apparently what caused all the issues with the monitor was a loose chassis screw
01:04 PM archivist: rofl
01:05 PM miss0r: so it was not getting the signal gnd onto the reciever of the monitor lol
01:05 PM miss0r: Thats one issue resolved. Now I can move on to the rest of my quite long list
01:06 PM miss0r: Thanks for the help. Had it not been for your steady guidance, I would probally have driven a fireaxe through the controller by now
01:07 PM archivist: I tend to put stuff down for a "period" no axe gets used
01:12 PM miss0r: I don't ever get to use an axe in here. But usualy around the time when I start to feel like it, Its time to put it down for a while ;)
01:12 PM miss0r: I'll call it a night. See you around
01:25 PM gloops: the old loose screw strikes again
01:32 PM anonnumberanon: I prefer a mid sized one handed sledge hammer for authoritatively distributing force towards ennemy hardware.
01:55 PM herbert__: do you know an IRC channel for MESA cards? :D
01:56 PM herbert__: that is not #linuxcnc
01:56 PM gloops: #here mainly
01:56 PM JT-Shop: yup this is the place to ask about Mesa cards
01:57 PM JT-Shop: or the forum
01:57 PM herbert__: allright... maybe tomorrow. sleep well to the sleepy folks, good day for the daylight people
01:59 PM gloops: im looking for a channel for bad backs
02:10 PM andypugh: Seems odd to pop in, ask if its the right place, and then pop out again without asking a question.
02:13 PM gloops: sure hes here fairly regularly
02:13 PM anonnumberanon: i need advice on this, what else should i train? https://files.fm/u/g466666a
02:13 PM anonnumberanon: LibreOffice Calc spreadsheet
02:14 PM gloops: hmm, seems the serial number on this hpc pulley is actually their phone number
02:16 PM gloops: but no serial number or any other mark, what am i supposed to do phone and say 'ive got one of your pulleys here'
02:18 PM gloops: yes i think that covers it all anonn
02:20 PM gloops: have you any previous experience of these kind of jobs at all?
02:20 PM anonnumberanon: some
02:21 PM gloops: any welding?
02:21 PM anonnumberanon: but i rarely use the right tools/methods so yeah
02:22 PM anonnumberanon: yes i've done a bit, maybe 30 hours on different exhaust projects and car sheetmetal (not nice, smooth body, more like wheel well, structural)
02:23 PM gloops: thats more than enough
02:24 PM gloops: if you can weld a cill on an old car you can weld anything
02:24 PM gloops: i especially like the 23/24
02:25 PM gloops: err 22/23
02:26 PM Tom_L: andypugh it takes all kinds...
02:28 PM gloops: anoon im curious - where are you going to begin with this build?
02:41 PM anonnumberanon: gloops, buy buying a few tools that can do the most things on that spreadsheet for the least amount of money
02:41 PM anonnumberanon: :)
02:42 PM anonnumberanon: and get a few samples of each material
02:42 PM gloops: well i think its a good approach anonn
02:43 PM gloops: remember the old adage 'failing to plan is planning to fail'
02:45 PM anonnumberanon: I'll add a list of tools to that spreadsheet once I got a bit more time.
02:46 PM gloops: when you start making the tools to do things youre getting to a higher level, it kinda shows that you understand the problem
02:46 PM gloops: not trying to say i am at any such higher levels but i know that
02:48 PM Tom_L: i make the tools that make the tools that...
02:48 PM Tom_L: :)
02:50 PM anonnumberanon: I'm trying to get a good tool from my parents for christmas ~$200 and a second one from me to myself for christmas, also ~200. So 2 major tools. All the small tools such as bit sets, drill and tap kit, I will get without counting the money.
02:51 PM Tom_L: good thing cause that would surprise you too
02:51 PM gloops: homo habilis 'the skilled man' first tool makers
02:52 PM gloops: although there is some evidence that crows used tools before humans - and still do
02:53 PM Tom_L: https://drillsandcutters.com/1-60-a-z-1-16-1-2x64ths-115-piece-kfd-black-and-gold-hss-split-point-jobber-drill-set/?utm_medium=googleshopping&utm_source=bc&gclid=EAIaIQobChMI4eiqjq2F2AIVQ7nACh1a6w4FEAQYAyABEgLFhfD_BwE
02:53 PM Tom_L: get a set like that and you'll have what you need
02:54 PM Tom_L: i get taps and reamers as needed
02:58 PM anonnumberanon: problem with these huge bit kits is when you break the size you need, that 200 dollars worth of bits becomes a paperweight :)
02:58 PM anonnumberanon: I'd rather buy 2 or 3 units of each size i need.
03:00 PM gloops: a drill press is a useful thing to have for this
03:00 PM gloops: and a centre punch
03:02 PM gloops: centre punch is probably more important than a fixed drill
03:03 PM anonnumberanon: drill press is tool #1 :)
03:03 PM anonnumberanon: centre punch is in the cart :)
03:03 PM anonnumberanon: i was wondering about dials, measuring tools and stuff, and last but not least a saw to cut aluminum and steel
03:04 PM anonnumberanon: (precisely)
03:04 PM roycroft: anonnumberanon: you buy the drill index full of drills, and you buy spares as needed
03:04 PM anonnumberanon: trying to buy one saw that will do both (changing saw blades) precisely, for less than $200 (not counting blades)
03:04 PM roycroft: you don't throw the whole thing away when you need to replace one drill
03:05 PM gloops: well, you can put a cutting disc in a wood chopsaw
03:05 PM rebecca: aluminium you can cut with woodworking saws. I love my sliding compound mitre saw for that
03:05 PM roycroft: if you're talking about a cutoff saw, you can use an abrasive disc saw (which is like a chopsaw), or a horizontal bandsaw
03:05 PM gloops: but you need to find or make the right fitting nuts - different diameter boss
03:05 PM roycroft: i prefer a band saw, personally
03:06 PM anonnumberanon: the horizontal bandsaw got my attention yes
03:06 PM roycroft: it's quieter and, although slower than a cutoff saw, can be operated without constant attention
03:06 PM roycroft: i.e. you don't walk far away from it, but you don't have to constantly "operate" it
03:06 PM roycroft: you start a cut and walk away to clean up the end of the previously cut piece or whatever while it's doing its thing
03:07 PM anonnumberanon: wow what?
03:07 PM roycroft: a bandsaw is going to be a lot more quiet than a cutoff saw and the kerf is a lot smaller
03:08 PM gloops: feeds itself through the metal
03:08 PM roycroft: and on the smaller sizes you can lift the table up and freehand cut curves or whatever in the vertical position
03:08 PM roycroft: you can get a 4x6" band saw fairly inexpensively
03:08 PM anonnumberanon: i was thinking a ~$150 bandsaw and for making workbench and other stuff, ~50 circular saw
03:09 PM roycroft: $260 at harbor freightright now
03:09 PM roycroft: and you can find a 20% off coupon every day of the week
03:09 PM roycroft: so that puts you at just over $200
03:09 PM roycroft: throw the crappy blade away and spend $30 on a good blade
03:09 PM roycroft: throw the crappy chinese fasteners away and replace them wigh good ones - another $10
03:10 PM anonnumberanon: The Wen 5" on Amazon for ~$220
03:10 PM roycroft: assume it's a rough kit that you'll have to disassemble, clean up, and reassemble
03:10 PM roycroft: and bob's your uncle
03:10 PM gloops: or one of these - https://www.ebay.co.uk/itm/Meddings-HS4-Power-Hacksaw/282701917118?
03:10 PM roycroft: i don't know anything about that wen
03:11 PM roycroft: the harbor freight 4x6 is a pretty ubiquitous saw - pretty much the standard starter bandsaw for a hobbyist metalworker
03:11 PM roycroft: versions of it are made by hf, grizzly, jet, and a number of other companies
03:11 PM roycroft: https://www.harborfreight.com/1-hp-4-in-x-6-in-horizontalvertical-metal-cutting-band-saw-62377.html
03:11 PM roycroft: the stand is crap
03:12 PM roycroft: but you can build a new stand or take it off the stand and mount it on a bench
03:12 PM roycroft: just keep in mind that if you use it in the vertical position, if it's mounted on a bench the table will be pretty high
03:12 PM roycroft: you might need to work on a step stool in that circumstance, which is not very safe
03:13 PM gloops: another grand old machine, i think its important to like the tools you use, and i like these old things, there comes a point where functionality must prevail over charm though i suppose https://www.ebay.co.uk/itm/Power-hacksaw-for-cutting-steel-barn-find/253304647000?
03:13 PM anonnumberanon: yeah that harbo freight looks more useful than the Amazon Wen one
03:14 PM roycroft: even though harbor freight machinery comes in "rough kit" form, for a beginner a new "rough kit" is usually better to have than worn out old iron
03:14 PM roycroft: with old used machinery one often needs to replace worn bushings, etc.
03:15 PM roycroft: which can be beyond not only the skills to effect repair, but the skills to diagnose the problems of a novice machinist
03:16 PM roycroft: filing down bits of rough castings and replacing bolts that you can deform with a pair of pliers with ones that actually work is well within a beginner's ability
03:16 PM gloops: well you may be right there roycroft, but on the other side of the coin a lot of new cheapo kit isnt functional from the start
03:16 PM roycroft: i'm not a huge fan of cheap asian imported machinery, but it makes sense in a lot of cases
03:17 PM roycroft: nor is a worn out old machine, often
03:17 PM roycroft: in the end it's up to the person buying the machine to decide
03:18 PM gloops: the solution is - buy quality new tools
03:18 PM roycroft: my sense, and i hope anonnumberanon doesn't take this wrong, is that he doesn't even know what he doesn't know yet about working with machinery
03:19 PM roycroft: btw, my 7x12 bandsaw came from hf
03:19 PM roycroft: i got it for a song - it was a floor model that had been stripped of several components
03:19 PM roycroft: i got it home
03:19 PM roycroft: put a real blade on it
03:19 PM roycroft: replaced the missing hardware
03:19 PM roycroft: and it cut dead nuts square right away
03:20 PM roycroft: i can only assume that while it was sitting on the store floor someone "abused" it into accuracy :)
03:20 PM CaptHindsight: Tom_L: https://www.youtube.com/watch?v=PJDv7Y6dUi0 Mig Weld Trouble-Shooting: Common Problems & Solutions
03:21 PM gloops: well i bought a new record bandsaw (wood) the blade guides were useless, eventually snapped one, made a new set of top and bottom guides for it, it worked nice for light use but when you asked for a bit more - not fit for the job, that would not happen on an old bandsaw
03:22 PM CaptHindsight: how many here are Russian hackers sent to infiltrate the channel?
03:23 PM roycroft: it boils down to a set of tradeoffs
03:23 PM roycroft: perhaps the best thing to do would be to find some old iron taht might be suitable, and bring someone who knows what to look for with when checking out the used machine
03:24 PM roycroft: if a wood bandsaw has fallen over or the upper arm knocked with a forklift or whatever, it can twist such that the wheels can never be adjusted parallel again
03:25 PM roycroft: and an unscrupulous person could slap some paint on the thing (and even "age" the paint) and make it look like it never suffered any damage
03:25 PM roycroft: just as example of something that can be wrong with an old machine
03:25 PM gloops: or another compromise - buy a used quality machine, not some victorian thing, a recent one, like you would buy a car, thorough inspection, consider the owner and its history, you can get a good machine for the same money as a new cheapo one
03:26 PM roycroft: yes, that can be a good deal
03:26 PM roycroft: here is the #1 caveat though:
03:27 PM gloops: yeah a got a flipsaw with a cracked casting, and i should have known better, it was barely visible, didnt notice it for months, tbh it never failed though -the motor eventually did
03:27 PM roycroft: about 100% of sellers who got the machinery from a school acution will promote it as "this was just used in a school schop - it was never used in a production environment, so it's not all worn out"
03:27 PM roycroft: if you don't know what you're doing
03:27 PM roycroft: never
03:27 PM roycroft: EVER
03:28 PM roycroft: buy a piece of machinery that came out of a school shop
03:28 PM rebecca: haha
03:28 PM roycroft: they have less wear than production shop machinery
03:29 PM roycroft: but they have much, much more abuse
03:29 PM CaptHindsight: I buy them, what are the odds of them crashing after they have been crashed many times before?
03:29 PM roycroft: i said "if you don't know what you're doing"
03:29 PM roycroft: you know what you're doing
03:29 PM gloops: they usually have foolproof stops set
03:30 PM roycroft: it is impossible to idiotproof a machine from a determined but ignorant high school student
03:30 PM roycroft: and high school shop teachers generally aren't as skilled at repairing/rebuild machinery as production shop maintenance crews
03:31 PM CaptHindsight: Homemade bandsaw mill https://www.youtube.com/watch?v=7_Gdp5255kw
03:31 PM CaptHindsight: I like how the rims look when they spin
03:31 PM gloops: perfect
03:32 PM CaptHindsight: and never try to slow the blade with your hands
03:32 PM XXCoder: very homebrew
03:32 PM gloops: those are alloys from a yahama RD 125 LC

03:40 PM gloops: stenner makes the best bandsaws
03:40 PM CaptHindsight: cantilevered swivel arm under cnc control, like a big SCARA but undersized
03:45 PM CaptHindsight: https://www.kickstarter.com/projects/1830738289/maslow-cnc-a-500-open-source-4-by-8-foot-cnc-machi but it hard to beat this awful setup
03:45 PM XXCoder: hard to beat price
03:46 PM CaptHindsight: except for this https://www.kickstarter.com/projects/2130625347/goliath-cnc-an-autonomous-robotic-machine-tool-for
03:46 PM XXCoder: enough for minor stuff, certainly not harder materials and stuff
03:46 PM XXCoder: that one is funny, its impossible to repeat
03:46 PM CaptHindsight: what to chefs use to cut large blocks or slices of cheese?
03:47 PM nallar is now known as Ross

03:49 PM CaptHindsight: fun/fund
03:50 PM XXCoder: buy one of those arms, attach chainsaw
03:50 PM XXCoder: and why chainsaw? just use giant endmill
03:50 PM CaptHindsight: robot with spindle
03:50 PM CaptHindsight: chainsaw is dramatic
03:50 PM XXCoder: https://www.youtube.com/watch?v=z_4WfBuYcNI
03:51 PM CaptHindsight: sound and flying ice
03:51 PM gloops: 6 axis breaker with spoon gouge blade would be a challenge
03:52 PM XXCoder: whats sad is that cnc cutting ice videos is rare lol
03:52 PM gloops: for the odd tree carving
03:52 PM XXCoder: https://www.youtube.com/watch?v=9SqTXHI7bkE
03:52 PM CaptHindsight: CNC Lathe for ice https://www.youtube.com/watch?v=YNJg1jtLF4U

03:58 PM XXCoder: his motor have snow getting in it
03:58 PM CaptHindsight: https://www.makerbeam.com/pledge.html why did I think of inventing t-slot?!
03:58 PM CaptHindsight: did/didn't
03:59 PM roycroft: no scammers are ok
03:59 PM roycroft: they should all be locked up
03:59 PM roycroft: but the credit card scammers are especially onerous these days
03:59 PM roycroft: they call from spoofed local numbers
03:59 PM XXCoder: just glad im immune to those
04:00 PM roycroft: for now
04:00 PM Deejay: gn8
04:00 PM XXCoder: roycroft: forever.
04:00 PM CaptHindsight: had one today from Alabamy
04:00 PM XXCoder: I dont have any hardline, and nobody can call my cell phone
04:00 PM roycroft: they'll start using tdd services some day
04:00 PM gloops: the bank will square you up
04:00 PM XXCoder: tdd needs hardline. :)
04:01 PM gloops: the trick is to have unique buying habits, the bank will go through the scammed purchases and check against your purchase history
04:01 PM XXCoder: not only that but if I answer with tty (been years since I used one now lol) scammer would hang up because of machine signal noises
04:02 PM roycroft: they are robocalls and they ignore everything you send them
04:02 PM CaptHindsight: XXCoder: I use those tones for my voicemail recording
04:02 PM roycroft: the scammers likely steal the voip trunks and computers thjey use to scam with anyway
04:03 PM roycroft: so they don't care
04:03 PM XXCoder: lol good thing I got no hardline then roy
04:03 PM XXCoder: my cell phone blocks all calls
04:03 PM CaptHindsight: you can funnel through an offshore trunk from anywhere
04:07 PM CaptHindsight: https://www.kickstarter.com/projects/chrisreilly/diylilcnc-20-open-source-plans-for-a-low-cost-cnc , looks like you add panels to hide the frame of the router
04:08 PM CaptHindsight: oh those panels are the frame of the machine
04:08 PM CaptHindsight: endless bad designs
04:09 PM roycroft: i am not going to get scammed
04:09 PM XXCoder: CaptHindsight: you should see aliexpress $150 cnc router lol
04:09 PM roycroft: but i am constantly annoyed by the phone ringing

04:09 PM XXCoder: probably still better than some of them kickstarter machines
04:10 PM gloops: diy cnc is a growing industry, selling plans and components, and lies
04:10 PM XXCoder: it follows logical design after all
04:10 PM roycroft: another scammer call
04:11 PM CaptHindsight: dc hobby motor spindle?
04:11 PM XXCoder: some scammers cannot hang up
04:11 PM roycroft: my number is unlisted, btw
04:11 PM roycroft: and on the do not call list
04:11 PM XXCoder: if you find one of em, play song forever
04:11 PM roycroft: but scammers ignore that crap completely
04:14 PM CaptHindsight: I need to cover one of the big machines here in wood grain contact paper and take some pics
04:15 PM gloops: good idea
04:16 PM gloops: i made this out of an old wardrobe and some skateboard wheels, see me cutting 1 inch at 500 ipm
04:17 PM CaptHindsight: lol
04:17 PM CaptHindsight: start a contest for best spoof of a bad machine design
04:19 PM gloops: that could be funny heh
04:25 PM CaptHindsight: cover in cardboard, add pulleys and strings

04:27 PM CaptHindsight: big time scammers https://en.wikipedia.org/wiki/Faraday_Future
04:28 PM CaptHindsight: kickstarter, makerfairs, stock market, your phone etc
04:29 PM CaptHindsight: one born every minute....
04:32 PM roycroft: and another cc scam call
04:32 PM roycroft: this is getting beyond ridiculous
04:33 PM CaptHindsight: new number?
04:33 PM roycroft: every number is a new spoofed number
04:33 PM roycroft: i was blacklisting the numbers for a while until i figured out that they're spoofed and random from within an exchange
04:35 PM CaptHindsight: I average less than 1/mo and it's been 1 every day or so since last week
04:36 PM CaptHindsight: maybe something is up, new lists or scam for the holidays
04:36 PM roycroft: i usually get one/day on my cell and one/month or so on my landish line
04:36 PM roycroft: which is voip
04:36 PM roycroft: now i'm up to, i think, 9 today so far
04:38 PM CaptHindsight: I answer and say that I'm a collection agency and have been waiting for them to call
04:39 PM roycroft: i don't have 30 seconds or more to listen to the robocall scam and then press a button to be connected to a live person in india
04:40 PM CaptHindsight: is it possible to forward the calls to those scam tech support virus callers?
04:41 PM MarcelineVQ: yes
04:41 PM MarcelineVQ: https://www.youtube.com/channel/UCnNlJNSRxa3PF8XrKHOEPug does it all the time :>
04:41 PM gloops: id wait for the live chat
04:42 PM CaptHindsight: forward the calls to (202) 326-2222 https://www.ftc.gov/contact
04:42 PM roycroft: 1. i'd have to be able to predict what the spoofed numbers are going to be
04:43 PM roycroft: 2. i would have to pay by the minute for the calls
04:43 PM gloops: btw aluminium prices are down
04:43 PM gloops: buy buy buy
04:43 PM roycroft: we need to eliminate the ability to spoof those numbers
04:43 PM * roycroft needs to sell some of his bitcoin before buying more stuff
04:44 PM gloops: bitcoin is booming isnt it?
04:45 PM CaptHindsight: roycroft: have you seen voip packets and the stack?
04:45 PM CaptHindsight: no way to block spoofing numbers
04:45 PM CaptHindsight: it's already illegal
04:45 PM CaptHindsight: just needs to be enforced
04:47 PM CaptHindsight: gloops: they are selling futures on them now
04:49 PM roycroft: bitcoin is absolutely booming
04:49 PM roycroft: it's up over US$17,000 today
04:54 PM gloops: if only id listened to that spotty kid 6 years ago
04:54 PM roycroft: i mined bitcoin for a year or so a few years ago
04:55 PM roycroft: i stashed my wallet away
04:55 PM roycroft: when i stopped mining the bitcoin was worth less than the cost of my mining hardware and the electricity i used
04:55 PM roycroft: now i can make a tidy profit
04:55 PM roycroft: so i dug out my wallet the other day
04:55 PM CaptHindsight: I didn't expect the markets to start trading them
04:56 PM roycroft: that's going to help keep the bubble from bursting
04:56 PM CaptHindsight: I thought they would be banned first
04:56 PM gloops: yeah might be a good time to sell, what goes up must come down
04:56 PM MarcelineVQ: that's what they said at 5k
04:56 PM roycroft: the only thing that's banned in this country now is not grabbing pussy
04:57 PM CaptHindsight: will end up like beenie babies
04:58 PM roycroft: i was going to sell when it hit $10k
04:58 PM roycroft: which was last week
04:58 PM roycroft: but then it hit $11k the next day
04:58 PM roycroft: and $12k the next
04:58 PM roycroft: i have to go set up an empty bank account to receive funds
04:58 PM roycroft: and then i can sell some
04:59 PM roycroft: there's talk of it hitting $50k by the end of next year
04:59 PM CaptHindsight: didn't they peak around 18K yesterday?
04:59 PM roycroft: my immediate goal is to sell enough to recoup my investment
04:59 PM roycroft: futures did
04:59 PM roycroft: 90 day futures
05:00 PM roycroft: also, my wallet is locked
05:00 PM roycroft: there's a long, random pass phrase to unlock it, and i have that printed out on a piece of paper
05:00 PM roycroft: i don't know where that piece of paper is
05:00 PM roycroft: i know i kept it
05:00 PM anonnumberanon: LOL
05:01 PM gloops: Marcel a bird in the hand is worth two in the bush
05:01 PM MarcelineVQ: a $30,000 dollar piece of paper
05:01 PM roycroft: so i have to search through my remaining boxes of paperwork that i haven't scanned and shredded
05:01 PM roycroft: there are only about 4 boxes left
05:01 PM roycroft: so it won't be too hard to find
05:01 PM roycroft: i just have to make the time to do it
05:01 PM roycroft: i'm not worried about it
05:01 PM roycroft: i am 100% certain that i have the information
05:02 PM roycroft: unfortunately i stopped mining right before i got a good password manager
05:02 PM gloops: not 99%?
05:02 PM SpeedEvil: roycroft: are we talking 'it would be nice' or 'I can buy nicoragua' levels of coin?
05:02 PM CaptHindsight: whatever happened to the bitcoin ASICs?
05:02 PM roycroft: otherwise it would be in the password manager
05:02 PM CaptHindsight: they raised money to fab them
05:02 PM CaptHindsight: and then did they not release them?
05:02 PM roycroft: i have one
05:02 PM roycroft: that's what i used to mine
05:02 PM SpeedEvil: All mining is ASIC now
05:02 PM roycroft: but it's old and slow
05:02 PM CaptHindsight: oh they did ship some?
05:02 PM roycroft: mining is really a lot harder now than it was
05:02 PM roycroft: it costs tens of thousands of dollars to set oneself up to mine bitcoin now
05:03 PM roycroft: speedevil: i have >1 bitcoin
05:03 PM roycroft: let's leave it at that :)
05:03 PM CaptHindsight: I figured that the Chinese would corner the market
05:03 PM SpeedEvil: roycroft: :)
05:03 PM MarcelineVQ: you could build a time machine and become satoshi
05:03 PM roycroft: and at $17k, >1 is a lot more than "it would be nice", but not quite "i can buy nicaragua"
05:04 PM roycroft: i have $400 invested in the asic hardware
05:04 PM roycroft: and about $400 in electricity
05:04 PM roycroft: so if i cash in $1k worth i've broken even plus money for a nice dinner
05:04 PM anonnumberanon: are you counting your time too?
05:05 PM anonnumberanon: to research it and any other activity related?
05:05 PM roycroft: no, but it was an educational exercise in the first place
05:05 PM roycroft: when i bought the hardware i figured that if i lost everything at least i'd have learned how cryptocurrency works
05:05 PM roycroft: and if i broke even on out of pocket costs it would have been a free education, which is nice
05:05 PM roycroft: i set my expectations low
05:06 PM CaptHindsight: get a partner in Taiwan, fab asics, mine just ahead of the curve but don't stand out
05:06 PM roycroft: and my expectations were met until recently
05:06 PM roycroft: there's not all that much bitcoin left to mine
05:06 PM roycroft: and it's extremely difficult to mine now
05:06 PM CaptHindsight: the Chinese guberment doesn't like them since they may be used to move currency out of China
05:06 PM roycroft: there are only 21 million bitcoins
05:06 PM roycroft: and ~15 million have been mined already
05:07 PM roycroft: guestimates are that about 5 million have been lost
05:07 PM CaptHindsight: can lost bitcoins be re-mined?
05:07 PM roycroft: so there are ~10 million available for circulation right now
05:07 PM roycroft: no
05:07 PM roycroft: when they're lost they're lost forever
05:07 PM roycroft: there's no way to know if they're actually lost
05:07 PM gregcnc: you won't trip over them on the street
05:07 PM roycroft: all we can know is that they have not been active
05:08 PM roycroft: a bitcoin is not just a number
05:08 PM CaptHindsight: what if you are from the future and can go back to mine them?
05:08 PM roycroft: it's a number with provenance
05:08 PM roycroft: lose the provenance and you have nothing
05:09 PM gregcnc: Capt I did, I'm retried since 1987
05:09 PM CaptHindsight: would you go back and kill Hitler?
05:09 PM roycroft: who's to say that things might not turn out even worse if hitler were killed?
05:09 PM CaptHindsight: I won't until 2213 :)
05:10 PM roycroft: altering the time-space continuum is tricky business
05:10 PM CaptHindsight: ok, then who could you kill to make things better?
05:10 PM roycroft: killing is not my thing
05:10 PM roycroft: and never could be
05:10 PM CaptHindsight: and isn't better subjective?
05:10 PM CaptHindsight: like great
05:11 PM MarcelineVQ: great isn't subjective, it's just context sensitive :D
05:11 PM roycroft: life is what it is
05:11 PM CaptHindsight: no yeasts were harmed in the making of this beer :)
05:11 PM roycroft: all we can so is try to make it better going forward
05:11 PM roycroft: and hope that our efforts are good
05:11 PM roycroft: many yeasts are harmed in making beer
05:11 PM CaptHindsight: the road is hell is paved with ....
05:11 PM roycroft: many, many yeasts
05:11 PM roycroft: billions of yeasts
05:12 PM MarcelineVQ: CaptHindsight: apricot pits
05:12 PM gloops: beer is only liquid bread
05:12 PM roycroft: but i don't make beer
05:12 PM roycroft: i make wort
05:12 PM CaptHindsight: have you seen bread in a can?
05:12 PM MarcelineVQ: uwort?
05:12 PM roycroft: the yeasts make beer out of the wort
05:12 PM roycroft: wort is beer precursor
05:12 PM gloops: no but ive never seen sliced beer either
05:12 PM MarcelineVQ: I'd like to try proper mead some time
05:13 PM gloops: mead isnt so easy
05:13 PM roycroft: i haven't made mead in a while
05:13 PM roycroft: i really need to do so
05:13 PM CaptHindsight: MarcelineVQ: tired of improper meads?
05:13 PM roycroft: it's not hard if you know what you're doing :)
05:13 PM roycroft: it does take patience though
05:13 PM roycroft: home fermented mead needs to age for at least a year before it's drinkable
05:13 PM MarcelineVQ: ehe, well just using that quantifier to mean I'd like a genuine artile not some company's idea of it
05:13 PM MarcelineVQ: *article
05:13 PM CaptHindsight: how about beer bread?
05:13 PM gloops: marcel you have already mentioned the finest wine there is - apricot
05:14 PM CaptHindsight: beer as a spongy solid
05:14 PM MarcelineVQ: wine is vile
05:14 PM roycroft: mead is fermented honey
05:14 PM roycroft: that's all it is
05:14 PM roycroft: if you buy a bottle at a market it's "real mead"
05:14 PM roycroft: if you make it at home it's
05:14 PM roycroft: "real mead"
05:14 PM gloops: honey and alcohol are the only 2 substances that can be absorbed directly by the stomach
05:14 PM CaptHindsight: powdered beer
05:14 PM MarcelineVQ: 'real mead, now will corn syrup'
05:14 PM MarcelineVQ: *with
05:15 PM roycroft: i've never had mead with corn syrup in it
05:15 PM MarcelineVQ: gloops: that's, just not true, are you being funny? :>
05:15 PM roycroft: that would be disgusting
05:15 PM roycroft: my problem with most commercial meads is that they're usually too sweet
05:15 PM gloops: marcel it is strue
05:15 PM Tom_L: JT-Shop, around?
05:16 PM MarcelineVQ: idk who told you that but they weren't being nice to you
05:16 PM CaptHindsight: https://spicespecialist.com/beer-powder
05:16 PM Tom_L: honey is deadly to infants
05:17 PM JT-Shop: yo
05:17 PM MarcelineVQ: there's too many infants anyway
05:17 PM gloops: i think youll find im right marcel
05:17 PM MarcelineVQ: waste of honey though :<
05:17 PM CaptHindsight: Tom_L: is that why babies don't keep bees?
05:17 PM roycroft: honey is easier to digest than table sugar
05:17 PM Tom_L: JT-Shop, i checked the gas flow and it was well above 20 cfh
05:17 PM MarcelineVQ: I won't, not because I'm unwilling, but because it's not true :o
05:17 PM CaptHindsight: Tom_L: can be too high a flow rate, did you see the videos?
05:17 PM Tom_L: JT-Shop, i ground all the edges with an angle grinder again
05:17 PM Tom_L: CaptHindsight i plan to
05:18 PM Tom_L: i turned it down to 20
05:18 PM roycroft: table sugar is sucrose, which is a disaccharide consisting of one molecule of fructose and one molecule of glucose
05:18 PM Tom_L: someone here said they use 15
05:18 PM MarcelineVQ: 15? that's wicked low
05:18 PM roycroft: humans cannot metabolise sucrose, so we have to break it down into fructose and glucose first
05:18 PM Tom_L: you're a rookie
05:18 PM roycroft: honey is a mix of fructose and glucose
05:18 PM MarcelineVQ: but try it because you might as well
05:18 PM CaptHindsight: Tom_L: it's worth it, he makes the mistakes and shows you the results
05:18 PM roycroft: the glucose can be absorbed by most organs in the body
05:18 PM Tom_L: i just haven't had a chance yet
05:18 PM roycroft: including the stomach
05:19 PM JT-Shop: Tom_L: my Millermatic 212 is set for 27CFH
05:19 PM roycroft: fructose can only be metabolised in the liver, though
05:19 PM roycroft: so it can be said more accurately that honey can be absorbed by the stomach better than table sugar
05:19 PM Tom_L: so i don't think that was the issue because i was well within that range
05:19 PM roycroft: but it cannot be said that it is completely abosorbed by the stomach
05:19 PM CaptHindsight: Tom_L: https://www.millerwelds.com/resources/weld-setting-calculators/mig-solid-core-welding-calculator
05:19 PM roycroft: i'm speaking of human metabolism
05:19 PM roycroft: other animals may differ
05:21 PM Tom_L: CaptHindsight, jt posted a couple yesterday too
05:21 PM JT-Shop: ouch a user on the forum is "fed up with the lack of documentation"
05:21 PM Tom_L: so tell him to get off his ass and write some
05:21 PM CaptHindsight: JT-Shop: for LCNC?
05:22 PM JT-Shop: aye
05:22 PM CaptHindsight: funny, it's actually one of the best documented open source applications
05:22 PM JT-Shop: sounds like that high maintenance guy I sold a couple of cards to lol
05:22 PM JT-Shop: thank you
05:23 PM Tom_L: those come with lifetime support to i'm told
05:23 PM pcw_mesa: JT-Shop I was trying to help but gave up /unsubscribed
05:23 PM JT-Shop: the AndrewHsasku guy?
05:23 PM pcw_mesa: yep
05:24 PM Tom_L: CaptHindsight, i wonder how i convert volts to a number on the dial
05:24 PM JT-Shop: Peter you spend a lot of time helping users, I wish I could answer more questions
05:25 PM MarcelineVQ: convert volts? usually the dial is already in volts on one dial, and feedrate on the other
05:26 PM Tom_L: err maybe that was you cap
05:26 PM CaptHindsight: https://www.millerwelds.com/equipment/welders/mig-gmaw/millermatic-212-auto-set-mig-welder-m00456
05:29 PM gloops: whats the max volts on the welder?
05:30 PM CaptHindsight: the Miller 212 has auto set
05:30 PM Tom_L: nice
05:30 PM JT-Shop: mine is this one https://www.millerwelds.com/equipment/welders/mig-gmaw/millermatic-212-auto-set-mig-welder-m00456#!/?product-options-title=millermatic-212-auto-set-mig-welder-aluminum-package-951177

05:30 PM CaptHindsight: https://www.millerwelds.com/-/media/miller-electric/imported-mam-assets/spec-sheets/6/0/5/dc12-46.pdf
05:31 PM gloops: id say about 100 for box section, 100-120
05:31 PM MarcelineVQ: 100 what
05:31 PM gloops: amp
05:32 PM MarcelineVQ: mig doesn't really deal in amp settings-wise
05:32 PM CaptHindsight: Tom_L: I run gas ~20cfm but thats on my gun and flow meter
05:32 PM MarcelineVQ: well, unless machines have change fairly in the last 8 years
05:32 PM CaptHindsight: cfh not cfm
05:33 PM JT-Shop: yea mine are just a scale like 1-7
05:33 PM Tom_L: CaptHindsight right that's where mine is set
05:34 PM CaptHindsight: Tom_L: what size nozzle and how far was it from the material?
05:34 PM Tom_L: i was pretty close to the work
05:35 PM Tom_L: which nozzle?
05:35 PM Tom_L: the gas one?
05:35 PM Tom_L: i'm not sure, whatever came with it
05:35 PM Tom_L: i'll go in a bit and run a few practice pieces
05:38 PM roycroft: i just adjust the feed and power knobs on my mig welder until i get a nice buzzing sound :)
05:38 PM roycroft: because 1-7 and a-h don't mean much to me
06:22 PM skunkworks__: sizzling bacon
06:23 PM Tom_L: ok i think i figured out at least one problem
06:24 PM Tom_L: i stuck a balloon on the end of the handle and disabled the feed and no gas is coming out. it's going somewhere though because the needle dips
06:25 PM Tom_L: i would think it would at least start to inflate the balloon
06:30 PM Wolf__: it should, might need to check the lines from the gas valve to the torch lead connector
06:46 PM Tom_L: damn feed hose had pulled out
06:49 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Welding/test_bead.jpg
06:50 PM Tom_L: probably could use a little more heat but a helluva lot better than it was
06:50 PM Tom_L: and move my slow arse a bit faster
06:53 PM Wolf__: looks much better with gas =) you could slow the feed down and work the puddle some, or crank the heat up
06:53 PM Tom_L: it needs more heat, i didn't have it up where it suggested
06:53 PM Tom_L: just wanted to be sure
07:24 PM Tom_L: Wolf__, any better? http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Welding/test_bead2.jpg
07:24 PM Tom_L: little more heat
07:25 PM malcom2073: Better than my welds
07:25 PM Tom_L: i was feeling like a rookie there for a while
07:25 PM Tom_L: just not that familiar with this mig machine
07:27 PM Tom_L: to avoid warpage i think i'll do a bunch of short runs like that along the edges
07:28 PM Tom_L: should help disapate the heat
07:28 PM Tom_L: i don't think i need a continuous bead everywhere
09:03 PM Tom_L: darn, missed him again
09:16 PM jesseg: Anyone know where I might look for the serial number on a mid 60's 15x42 Cincinnati Hydroshift lathe?
09:26 PM MarcelineVQ: Tom_L: flux core?
09:27 PM Tom_L: ?
09:27 PM Tom_L: no i don't use the stuff
09:27 PM MarcelineVQ: ah guess not, the weld is a ltitle clean for that, it's just that I'm curious about all the powder on the sides
09:28 PM MarcelineVQ: and the flux-like bead at the end of the welds
09:28 PM Tom_L: i'm not sure what that is
09:28 PM Tom_L: i'm using argon / co2 mix
09:29 PM MarcelineVQ: it'd be a good idea to find out asap. the welds are looking much nicers but dust and glass suggest something else going on, to me. what's your wire roll say on it?
09:30 PM Tom_L: i'm not sure what it is
09:30 PM MarcelineVQ: does it snap easily?
09:30 PM Tom_L: snap?
09:30 PM Tom_L: the wire?
09:30 PM MarcelineVQ: the wire
09:30 PM Tom_L: no
09:31 PM MarcelineVQ: that residue is exeedingly flux-like ehe
09:31 PM Tom_L: could be something from the metal
09:32 PM Tom_L: it had alot of paint on it i ground most off
09:34 PM MarcelineVQ: maybe, paint should burn rather that make glass though, strange strange. weld's much improved at least
09:49 PM SpeedEvil: Some paint is very high inert filler
09:50 PM Tom_L: i'm fairly sure it was some kind of industrial paint
09:54 PM jesseg: is the wire copper clad?
09:54 PM Tom_L: yes
09:55 PM jesseg: Could it be copper oxide or dust that gets spattered out?
09:59 PM MarcelineVQ: hmm various suggestions here http://www.mig-welding.co.uk/forum/threads/newbie-needs-help-brown-powdery-residue.14226/ leans towards torch angle technique and a bit more gas flow being helpful. it'd be nice to be able to see the questioner's pcitures though to be sure his brown soot is the same as yours :X
10:01 PM MarcelineVQ: other searches for mig brown soot all are suggesting more gas
10:03 PM MarcelineVQ: "If he is like most of us, his tacks are the first thing he welds after welder has sat idle....In that case the shielding gas has usually bled from hose and it needs purged." "It's become a habit with me to open regulator, turn on machine, flip to spool gun mode and purge, then flip back to mig mode and hit it with tacks" interesting
10:04 PM jesseg: I wonder about that. It is kind of the color of iron oxide :P
10:06 PM MarcelineVQ: there's silica in some wires and metals which seems to be the cause of the flux-like glassing on the weld
10:34 PM `Wolf: I notice that on my welds time to time, never really cared. none of the trucks I have welded have fallen apart yet
10:34 PM `Wolf: unlike one of the other shops that has had hitch plates come off on one of their jobs....
10:35 PM `Wolf: always good when you have a 12,000lb trailer pull the hitch off the truck while going around the beltway
10:37 PM MarcelineVQ: yikes
10:38 PM MarcelineVQ: I've had a 30ft flatdeck pop off and that's plenty scary enough, something biggeris heart attack fuel
10:39 PM `Wolf: https://i.imgur.com/gzw7p90.jpg some of the stuff I do
10:39 PM `Wolf: https://i.imgur.com/wSkwsNi.jpg
10:40 PM `Wolf: =) https://i.imgur.com/yERX7l3.jpg
11:05 PM Contract_Pilot: Sup...
11:05 PM Contract_Pilot: lots done last 2 days.....
11:05 PM Contract_Pilot: wheww...
11:05 PM Contract_Pilot: lots to do befor the 18th
11:06 PM Contract_Pilot: then down ultra light duty for 6 weeks
11:07 PM Contract_Pilot: I scored a BOB for a tormach lathe will be fun to play this weenend
11:07 PM `Wolf: cool
11:08 PM `Wolf: I have my machine move happening tomorrow
11:10 PM Contract_Pilot: local machine shop got m 20 to boar out a pulley WTF
11:10 PM Contract_Pilot: but was done on the spot...
11:10 PM Contract_Pilot: new pulley proper size was 16.00 shipped....
11:11 PM Contract_Pilot: So all the motors are installed.
