12:04 AM Connor: Those of you who have manual lathes and installed DRO's.. What do you do about the X scale covering up the cross-slide lock? On my lathe, it has a single set screw used to lock the cross slide, but, if I install the scale, it'll cover it up..
02:11 AM Deejay: moin
05:01 AM SpeedEvi is now known as SpeedEvil
05:14 AM jthornton: morning
05:14 AM XXCoder: yo
06:26 AM taloot: hello
06:27 AM taloot: im doing hand held linuxcnc
06:27 AM XXCoder: hello, this is cnc machines controller chat though
06:27 AM XXCoder: oh wait you saif linuxcnc not just linux
06:27 AM XXCoder: hmm whats it supposed to do?
06:28 AM taloot: i will show u somthing that gave me the idea
06:29 AM taloot: http://www.daincube.com/wp-content/uploads/2018/11/teach-pendant-main-image.png
06:30 AM taloot: i will do similar case and use raspberry 4
06:30 AM XXCoder: that, only it literally controls entire machine and not just for jogging etc
06:30 AM taloot: yes
06:30 AM XXCoder: pretty cool. MESA?
06:30 AM taloot: complete controller in hand
06:30 AM taloot: u can unplug it from machine
06:31 AM taloot: this is usefull when u place machine outside
06:31 AM taloot: yes
06:31 AM XXCoder: heh thats little bit better concept than my hobbyist cnc linuxcnc computer device with all built in
06:31 AM taloot: ethernet mesa or the cape like
06:31 AM taloot: both cheap
06:31 AM taloot: IPS 1920x1080
06:32 AM taloot: now computers become smaller and faster
06:32 AM XXCoder: what you think BOM would be?
06:33 AM taloot: hmmm... i will use alumnum for my prototype
06:33 AM taloot: for the housing case
06:33 AM taloot: buttons, i have good source in china for that
06:33 AM taloot: also the screens
06:33 AM taloot: the memebrine keypad
06:33 AM taloot: i can costumize it cheaply
06:50 AM Tom_L: morning
06:50 AM taloot: morning
06:50 AM taloot: its 3:44om here
06:50 AM taloot: pm
07:00 AM jthornton: morning
07:01 AM _unreal_: yawn
07:01 AM _unreal_: I was like Om? wtf is om
07:03 AM _unreal_: jthornton, OMG the parts I'm getting from from the satellite.
07:04 AM jthornton: you shot down a satellite?
07:04 AM _unreal_: everything I need yep
07:05 AM _unreal_: https://drive.google.com/open?id=1dFY3pm4vfysS3BCXWL54f5nyL_M4Xa41
07:06 AM _unreal_: for the Z multi axis build
07:24 AM taloot: profssional welding
07:25 AM XXCoder: was that former cnc controlled robot arm?
07:25 AM _unreal_: that was part of a satellite
07:26 AM _unreal_: marine one that has tracking
07:26 AM XXCoder: hows you get one?
07:32 AM SpeedEvil: https://www.masinaelectrica.com/130kw-motor-high-rpm-version-2018-in-construction/ neat
07:53 AM _unreal_: hi sorry I was desoldering parts
07:53 AM _unreal_: XXCoder, I get them every now and then
07:53 AM _unreal_: the yachts at work throw them away
07:54 AM XXCoder: yachts at work?
07:54 AM _unreal_: that was a 60" seatech satellite
07:54 AM _unreal_: bldc motors on them
07:54 AM _unreal_: yes I work on boats
07:54 AM XXCoder: lol and I thought my reclaiming 2 $225 led lights was all kinds of awesome lol
07:55 AM _unreal_: you should see the shit I get
07:55 AM _unreal_: I have a bunch of PLC stuff I'll never use going to sell it likely
07:55 AM XXCoder: make robot arm cnc
07:56 AM XXCoder: or even betetr, 3d welder printer
07:56 AM XXCoder: saw video of it, wow
07:56 AM _unreal_: That sat. frame I'm going to turn into a 5axis setup for the new work cnc machine I'm building
07:56 AM _unreal_: I think I'm going to change my original cnc machine design so i can use that frame
07:56 AM XXCoder: my lights is still incomplete :(
07:56 AM _unreal_: to more of a box
07:57 AM _unreal_: XXCoder, few weeks ago I got a "power board"
07:57 AM XXCoder: hey can I use saw to cut arylic tube, after taping it?
07:57 AM _unreal_: one of those motorized skate boards
07:57 AM _unreal_: the controller was blown so. the board is $2k the replacement controller $200
07:57 AM _unreal_: lol found in the trash
07:57 AM XXCoder: jeez
07:58 AM XXCoder: I would just swap board and save 1800
07:58 AM XXCoder: easy fix and ebay
07:58 AM _unreal_: "boosted"
07:59 AM _unreal_: https://en.wikipedia.org/wiki/Boosted_(company)
08:00 AM _unreal_: $1500 what ever
08:00 AM _unreal_: still NOT cheap
08:01 AM XXCoder: yeah
08:01 AM _unreal_: XXCoder, Whats killing me is I want to get these motor controllers working
08:01 AM _unreal_: design a new pcb and transfer them
08:01 AM XXCoder: cant buy parts?
08:01 AM _unreal_: a3936sed
08:01 AM _unreal_: they chips are no longer in production yet EVERY sat... uses these chips
08:02 AM _unreal_: https://drive.google.com/open?id=1dFzCnE5WyuvpblcYOoAwjGFrkDqiTDGc
08:02 AM XXCoder: lol well time for me to sleep. later :)
08:02 AM _unreal_: the motor control board is just 6 chips a few resistors and caps everything is on the top side
08:02 AM _unreal_: What!!!
08:03 AM _unreal_: and XXCoder yes I think you could call it a robot control arm only it only aimed a sat. dish
08:16 AM Rab: XXCoder, I've had no problem cutting acrylic tube with a hacksaw. Heat is the big problem. You want to keep cutting speed low, and maybe water cool.
08:18 AM Rab: _unreal_, why not reuse the existing controller board? It's presumably got everything needed to support the chip.
08:20 AM _unreal_: Rab, as far as I can tell
08:20 AM _unreal_: the controllers are not setup in a way I could really use them
08:21 AM _unreal_: I'd have to modify them. only one hall sensor is tied to two of the controllers
08:21 AM _unreal_: 3 chips but only one reads all 3 hall sensors
08:21 AM _unreal_: the wireing is slightly different between the chips thats why I say I need to build a new board design
08:22 AM Rab: Hmm, not something you can cut traces and wire around?
08:22 AM _unreal_: I could but why
08:22 AM _unreal_: most of the traces are under the chip
08:23 AM _unreal_: I'm not kidding when I say I REALLY cant
08:24 AM _unreal_: Rab, I'd gladly send you a board and a bldc motor if you think you could redo a board design to transfer the parts to
08:24 AM _unreal_: would be nice to turn them into nice motor controllers
08:24 AM Rab: _unreal_, I am interested in the project but I have no spare time. ^_^
08:24 AM jthornton: what's spare time?
08:24 AM _unreal_: no free shit for you :)
08:26 AM Rab: _unreal_, my free shit cup runneth over.
08:27 AM _unreal_: same
08:28 AM _unreal_: Rab, as I was saying though I get these sats now and then when ever one is tossed IF I find out about it before it gets tossed in the trash
08:28 AM _unreal_: so I have an infrequent endless supply
08:30 AM Loetmichel: *GNIHIHI* dell server just fooled the coworker... "can you help me, michel? i have system in the measurement chamber that shows no picture. LED on the front is on, so its running, but its afully quiet, too..." $me looks: ID led is on. Powerled is off... *Press power button* *instant jet engine* "NOW its running!" ;)
08:30 AM _unreal_: some times there are 3-4 in the yard then next month nothing and mabe one the next month after that...
08:32 AM gregcnc: ughh, the BMW isn't charging the battery seems to be the cable between alt->starter->hood terminal. which is under the intake manifold :-/
09:11 AM * Javabean figured out how he went from mindless machining videos to food videos...
09:13 AM Javabean: WARNING video may not be safe for your diet https://www.youtube.com/watch?v=P53fcAIMYKc
10:46 AM _unreal_: quiet
10:47 AM t4nk_freenode: yes, quite.
10:48 AM _unreal_: quite you
10:48 AM _unreal_: t4nk_freenode, my latest find https://drive.google.com/open?id=1dFY3pm4vfysS3BCXWL54f5nyL_M4Xa41
10:48 AM _unreal_: at work the boats toss them out now and then
10:49 AM _unreal_: its the main frame to a seatech satellite
10:49 AM _unreal_: for a mega yacht
10:49 AM _unreal_: whats left of everything I ripped off
10:49 AM SpeedEvil: https://www.amazon.co.uk/3Dconnexion-3DX-700059-Spacemouse-Compact-Mouse/dp/B079Z3T2XC - neat
10:49 AM SpeedEvil: (I did not pay this for it)
10:49 AM SpeedEvil: trying blender again, it's helping.
10:50 AM _unreal_: I should do more with blender
10:50 AM SpeedEvil: The new 'collections' in 2.8 has solved one of my issues with 2.7
10:51 AM SpeedEvil: - you can basically do 'add object -> sofa'
10:51 AM SpeedEvil: where that's an instanced copy from a library
10:52 AM _unreal_: hum
10:55 AM _unreal_: bbiab going out to have some LATE breakfast
10:55 AM _unreal_: only 78F outside :)
10:57 AM Tom_L: brrr
10:57 AM Deejay: re
10:58 AM Tom_L: SpeedEvil, i considered one of those at one point
10:59 AM Tom_L: they had the full blown version at the vo'tech and nobody used them
11:02 AM Tom_L: https://www.3dconnexion.com/products/spacemouse/spacemouse-enterprise.html
11:02 AM Tom_L: like those
11:06 AM SpeedEvil: yeah - this was cheap on ebay
11:06 AM Tom_L: those are typically used left handed
11:18 AM roycroft: i use mine all the time with my laptop
11:19 AM roycroft: it makes solidworks possible to use on a laptop with a touchpad
11:25 AM roycroft: damn thing weighs about as much as the laptop though
11:53 AM jthornton: https://youtu.be/qbnPXC39LRc
11:54 AM _abc_: Hi. Does anyone have a link on this type of universal driver? https://imgur.com/gallery/b7NCLA6
11:55 AM _abc_: It slides a bit but there would be ways around that
12:00 PM SpeedEvil: They are bloody everywhere
12:01 PM Tom_L: jthornton, 404
12:01 PM SpeedEvil: https://www.ebay.co.uk/itm/Magical-Grip-Universal-Gator-Socket-Adapter-with-Power-Drill-Adapter-Tool-7-19mm/372821218712
12:01 PM SpeedEvil: (*)
12:01 PM SpeedEvil: *) May not actually be magical
12:02 PM Tom_L: nm, it's my isp
12:20 PM Tom_itx: damn jthornton i didn't realize that thing was that tiny
12:54 PM jthornton: that's the smallest one I have 65mm
01:00 PM roycroft: so have any of you checked out the shaper origin hand-held cnc router?
01:30 PM drdoc: roycroft: that looks like a solution looking for a problem
01:32 PM roycroft: i'm not sure about it, drdoc
01:32 PM roycroft: it could be a game-changing product
01:32 PM roycroft: a lot of small shops just don't have the space for a cnc machine
01:32 PM drdoc: I mean I understand the application - CNC work without an XY envelope
01:33 PM roycroft: i just wonder how well it will work in a production environment
01:33 PM roycroft: it's a very clever idea
01:34 PM roycroft: but if one has to move the machine very very slowly it will probably not do well
01:34 PM roycroft: and i wonder how quickly it will react if it's moved to the wrong position suddenly
01:34 PM drdoc: that was my thought, and that a hard spot or void could kick it past its tolerance
01:35 PM drdoc: ever use a foot drill?
01:35 PM roycroft: no
01:36 PM drdoc: one of the most terrifying power tools ever
01:36 PM roycroft: at the office where i work we operate two businesses
01:36 PM drdoc: it's a table-sized drill press with a magnet in the foot
01:36 PM roycroft: one of them is a print ship
01:36 PM roycroft: shop
01:36 PM roycroft: a year or two ago my boss bought a new, electric cutter
01:36 PM roycroft: a nice machine - it has presets for the paper stops and can cut a full ream of paper at a time
01:37 PM drdoc: for drilling holes in steel plate or assemblies that's too large or heavy for a drill press
01:37 PM roycroft: to operate it there are two deadman switches that have to be activated simultaneously, so as to make sure one doesn't have a stray hand in the way of the cutter
01:37 PM roycroft: that slows things down a bit, so my boss disabled those switches immediately and replaced them with a foot switch
01:38 PM roycroft: i physically shuddered when i saw his mod
01:38 PM drdoc: trying to drill even mild steel to >1" with a hand drill is a non-starter, so the foot drill gives you alignment, location, and a bit of leverage
01:38 PM roycroft: oh, you're talking about a mag drill
01:38 PM roycroft: yes, i've used those
01:39 PM drdoc: yeah, safety switches usually aren't really optional
01:39 PM roycroft: i thought you were talking about a drill press where the quill is operated by a foot pedal
01:39 PM roycroft: which i've seen
01:39 PM drdoc: yeah, they're nice
01:39 PM roycroft: hence my divergence on the topic of the cutter
01:39 PM roycroft: i feel the same way about a drill press with a foot pedal
01:40 PM roycroft: too many people don't pay attention to what they're doing and perform stupid, dangerous operations
01:40 PM drdoc: but I thought of the mag drill immediately when I saw that shaper product
01:40 PM roycroft: hmm
01:40 PM drdoc: a 1m^2 router with rare-earth magnets as feet
01:40 PM roycroft: i don't see the connection there
01:41 PM drdoc: you could clamp it to a large sheet
01:41 PM roycroft: the machine i'm talking about looks like a conventional router
01:41 PM drdoc: yes, I'm looking at it
01:42 PM roycroft: but it is position aware, and can compensate for a human's jerky, inaccurate positioning, to a degree
01:42 PM drdoc: and talking about going a step past that
01:42 PM roycroft: it claims to hold a tolerance of 0.001" when hand-operated
01:42 PM roycroft: which is pretty damn good
01:42 PM drdoc: what happens when you *rotate* it, though?
01:43 PM roycroft: it knows that you rotated it
01:43 PM drdoc: sweet
01:43 PM roycroft: it operated with a couple optical sensors
01:43 PM roycroft: you cover the workpiece with some indexing tape
01:43 PM roycroft: all over the place
01:43 PM drdoc: right
01:43 PM roycroft: then you go through a calibration exercise, where it reads the tape and determines its location
01:43 PM drdoc: ok
01:44 PM roycroft: then you run the program, and it tells you roughly how to move the router
01:44 PM roycroft: and it follows your movements and compensates for your inaccuracies
01:44 PM drdoc: right
01:44 PM roycroft: if you move too far off it retracts the cutter and yells at you
01:44 PM drdoc: lol
01:44 PM roycroft: since it has multiple optical sensors it can tell if you rotate it
01:45 PM drdoc: ok, cool
01:45 PM roycroft: so if you put down enough of the indexing tape in enough locations it should never get lost
01:45 PM roycroft: and i'd probably do a dry run of the program before doing the actual job, so i'd know if i messed up on the indexing ahead of time
01:45 PM drdoc: I think a shapeoko-like router would be more practical in the end
01:46 PM roycroft: but the device may also be able to tell you that
01:46 PM roycroft: i use a router table and templates for most of what i do
01:46 PM roycroft: but some things would be nicer with cnc
01:46 PM drdoc: make the base external to the envelope, so z0 is *under* the router frame
01:46 PM roycroft: i'm not seriously looking at buying that thing - at $2.5k it's a bit expensive
01:47 PM drdoc: magnets in the frame base, and magnets under the workpiece
01:47 PM roycroft: but the idea is interesting
01:47 PM drdoc: it is interesting
01:47 PM roycroft: and i'm one of those people who is spatially challenged
01:47 PM roycroft: i'd love to build a cnc router, but i don't have the room to spare
01:48 PM roycroft: a really small one would be useless
01:48 PM roycroft: and a decent size one would take up far more space than i have available
01:48 PM drdoc: I'm just not convinced it would work as designed
01:48 PM roycroft: it's been proven to work
01:48 PM roycroft: but whether it works in production is what i question
01:48 PM drdoc: that
01:48 PM roycroft: also, what happens when one starts climb routing with it?
01:49 PM drdoc: at the price, it would have to be a production-ready tool
01:49 PM roycroft: hopefully it will just retract the cutter and yell some more
01:49 PM roycroft: yeah
01:49 PM roycroft: for what it is, it needs to cost <$1k
01:49 PM drdoc: yeah
01:49 PM roycroft: if it catches on it probably will come down to that price point
01:49 PM drdoc: am I describing my idea clearly?
01:50 PM roycroft: yes, you are
01:50 PM drdoc: in my head, it's something that could hang on the wall when not in use
01:50 PM * roycroft also has no wall space :)
01:50 PM drdoc: heh
01:51 PM roycroft: i'm building a clamp rack - i should finish it today
01:51 PM drdoc: then you're scrooged all around
01:51 PM roycroft: because i have a bunch of big bessey revo clamps that have no home
01:51 PM drdoc: nice
01:51 PM roycroft: the clamp rack is going to live in the lean-to shed next to my woodworking shop, because there is no room for it in the shop
01:51 PM drdoc: oh, and thanks for the memory cue!
01:51 PM roycroft: so i'll have to go out to the shed every time i need clamps
01:52 PM drdoc: I have a big, old Wilton bullet vise
01:52 PM roycroft: i'm going to build racks for my f-style and tradesman clamps too, and those racks will have to live in the shed
01:52 PM drdoc: 4" jaws, 7" throw
01:53 PM drdoc: I keep forgetting to draw up soft jaw covers for it
01:53 PM roycroft: all my c clamps (g cramps for you brits) live in buckets in my welding shop
01:53 PM drdoc: mine usually hang on cables stung under shelves & tables
01:53 PM drdoc: strung
01:54 PM drdoc: my storage unit got cleared out about 18 months ago
01:56 PM drdoc: 2 6x4' welding tables, a jewelers' lathe, 3 3-phase 2HP motors, a MIG welder, a Victor torch set and tanks, a 100lb farrier's anvil, a 162lb ACME anvil that belonged to my great gandfather
01:56 PM drdoc: and a couple hundred pounds of welders' vise-grip clamps and C clamps
01:57 PM drdoc: plus several grand in electronics, computer gear, and furniture
01:58 PM drdoc: I wanted to cry
01:59 PM drdoc: also a propane forge and a 200lb cedar anvil stand
02:06 PM _abc_: drdoc: you've been burgled?
02:06 PM _abc_: Storage unit is stand alone with public access to door?
02:07 PM drdoc: yes, and yes
02:07 PM _abc_: How much do they charge for this. I hope it was free.
02:07 PM _abc_: Whenever I see ACME anything I think about the cartoon.
02:07 PM drdoc: and if the storage company had allowed me to use my own locks, I'd probably not have been a target
02:07 PM _abc_: probably
02:08 PM drdoc: me too, and I believe that ACME's anvils, circa early-20th-century, are the cartoon stuff's genesis
02:09 PM drdoc: most of my jewelry hand tools, including files and a Smith Little torch setup, and my hammers were at home
02:10 PM drdoc: I also lost 25-30 Model M keyboards
02:10 PM drdoc: which translates to about $1500 in keyboards alone
02:12 PM drdoc: I still get a bad BP spike every time I think about it
02:44 PM _abc_: drdoc: no surveillance video, nothing? You could sue the storage company I think. Dunno if possible, I am in Eastern Europe.
02:46 PM _unreal_: sup
03:39 PM roycroft: _abc_: in the usa, the standard agreement for a storage unit, which must be signed before the unit is made available, indemnifies the owner of the unit from all liability for theft, fire, acts of nature, etc.
03:39 PM roycroft: one can sue anyone for any reason in this country, but one would lose in this case if such an agreement had been executed
03:42 PM Javabean: drdoc, if they supplied the locks they COULD be liable... have to talk to a lawyer, but they could be held liable if you claim neglegence on their part
03:42 PM _abc_: roycroft: that is insane. They should pay people to put things in there. Basic insurance is mandatory even if it is building insurance and capped.
03:42 PM _abc_: I fond the lack of at least a DVR covering the doors undefendable.
03:42 PM _abc_: A DVR costs under $100 now.
03:43 PM _abc_: And just a few dollars per month to operate.
03:43 PM _abc_: Power and perhaps swapping media every few months as it wears out.
03:49 PM _unreal_: hehe drdoc I read that a few times stung ?stung? stung.... ? strung? oh strung
03:55 PM _unreal_: looking for a good adjustable holding clamp for my digital indicator
04:09 PM Deejay: gn8
04:12 PM XXCoder: Rab: thanks
04:49 PM headrx: Wondering if anyone here has built there own 5 axis CNC comparable to the Pocket NC v2 , or have any recommendations on something comparable?
04:49 PM Rab: SpeedEvil, Spacemouse works great with FreeCAD!
04:50 PM Rab: (And SolveSpace, when support isn't broken)
04:53 PM Rab: roycroft, I hear the main annoyance with the Shaper Origin is the amount of expensive ShaperTape you have to apply and burn through.
04:53 PM XXCoder: jthornton: lol
04:53 PM XXCoder: just read about rspi4 hdmi killing wireless if at certain resolution
04:54 PM Rab: "Each [$18] roll of ST1-150 ShaperTape is 150-feet in length. The amount of tape required for operation is proportional to the scale of the project you're working on. For reference, 150-feet provides ample coverage for approximately one and a half standard 4' x 8' sheets of plywood."
04:54 PM headrx: No one has opinion on my question ?
04:55 PM XXCoder: hey dunno
04:55 PM XXCoder: I just have cnc router for home :)
04:56 PM XXCoder: only thing I read is guy making 4th axis gear, one side is little bit oversize bronze and other is normla steel
04:56 PM XXCoder: so bronze deforms slightly and leaves zero backlash
05:00 PM SpeedEvil: Rab: I would be putting it on an appropriate tape, and release tape.
05:01 PM Rab: SpeedEvil, the Shaper?
05:01 PM SpeedEvil: yes
05:02 PM SpeedEvil: Tape the tape to a tape that can be removed and replaced, and then tape that tape to a clean bit of tape that is disposed of.
05:03 PM Rab: headrx, Pocket NC is notable for its miniscule work envelope. Most DIY efforts seem to go in the router direction just to get decent area.
05:04 PM Rab: Musta been something I said.
05:07 PM Rab: SpeedEvil, sounds good. You could also mount the tape to e.g. brass strips which tack in place.
05:07 PM Javabean: that wasn't very nice of you, poor person had to flee to save themself
05:07 PM Javabean: ;p
05:08 PM Rab: I think there might be a clandestine effort to clone the ShaperTape, maybe a graphic that can be laser printed.
05:09 PM Rab: Javabean, it's a shame, because I had so much baseless pontification ready to spew.
05:09 PM XXCoder: lol
05:09 PM XXCoder: dont pcket nc also have some backlash issues
05:09 PM Javabean: what?? you would LIE!!! on the internet!
05:09 PM XXCoder: saw some videos and theres usually small amount of chatter
05:10 PM Javabean: i have seen a few of them without chatter. but they didn't "look" like they were going fast with their cuts
05:10 PM Rab: XXCoder, it sure looks solid...but maybe it vibrates a lot due to low mass?
05:10 PM XXCoder: dunno
05:11 PM taloot: pocketnc expansive toy
05:13 PM Javabean: i think he meant "expensive", i don't know of any expansions you can do to pocketnc
05:13 PM Rab: I was gonna cite Tom_itx's small mill as a nice starting point. Could easily add rotary axes, still vast work area compared to Pocket NC.
05:14 PM Javabean: is it anygood? is there documentaries on it?
05:14 PM XXCoder: pocket nc perfect for making small stuff
05:14 PM XXCoder: I guess anyway
05:14 PM XXCoder: I still dont know if it comes with own cam so guy can make stuff
05:14 PM Rab: Javabean, he posted a bunch of pics a year or two ago. I think it turned out well.
05:15 PM Javabean: hmm... any links to this person?? tom_itx? youtube?
05:15 PM Rab: XXCoder, it was supposed to come with revolutionary 5-axis CAM. I think they now have some sweetheart deal for Fusion360.
05:15 PM Rab: Javabean, ask him.
05:16 PM Javabean: Hello Tom_itx, do you have any links to your works? someone has been gushing about your projects and i was currious. Sincerely Javabean
05:16 PM Rab: Javabean, http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/
05:16 PM Javabean: meh, i don't think that letter will work well for me
05:17 PM Rab: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Mister_plumbing1.jpg
05:17 PM Javabean: looks nice, Rab
05:20 PM Rab: Javabean, https://www.youtube.com/channel/UCoG_JaILNz3Q-jBZ5MiK1dA/videos
05:21 PM Javabean: hey, wait... its a no-ip address, i am not killing on tom_itx's home system... right?? i seem to have a curse for overloading pc's
05:26 PM Tom_itx: ?
05:26 PM Tom_itx is now known as Tom_L
05:34 PM Javabean: no-ip is a "host" that lets you run a site/server/etc on any system you can get connected to them with... be it a server at the bigplaces or a raspi leaning against your home modem
05:34 PM Tom_L: yeah
05:34 PM Tom_L: i've had it up for a very long time
05:46 PM skunkworks: Javabean: I have cool things too
05:47 PM Javabean: LIES!!! only i have the cool things, all your stuff is stinky
05:47 PM Javabean: ;p
05:47 PM skunkworks: pshaaa!@
05:48 PM skunkworks: http://electronicsam.com/images/KandT/oldkandt.JPG
05:48 PM Javabean: that labcoat is NOT flattering for you
05:49 PM skunkworks: well - that guy is probably dead now... That was circa 1960
05:51 PM skunkworks: https://youtu.be/fTI_Ypv4FQE
05:51 PM XXCoder: one of earliest cnc
05:52 PM skunkworks: yes - Milwaukeematic IIIb.. So 3rd? ;)
05:53 PM Javabean: ... dude, thats some heavy metal
05:53 PM CaptHindsight: https://youtu.be/ri_LFckaT7g?t=273
05:54 PM CaptHindsight: new, clean and everything lines up
05:54 PM jthornton: be fun to fly a whoop around in that shop
05:55 PM CaptHindsight: when toes that happen except for at the factory
06:01 PM jthornton: I wonder what I should try and sell my Enco 6x42 mill for...
06:01 PM Javabean: give you treefiddy
06:02 PM Javabean: but thats all i can afford!!! my mills will probably be custom made by me using melted down steelies
06:02 PM Javabean: since i seem to be able to get them for free
06:03 PM CaptHindsight: jthornton: what shape is it in?
06:04 PM jthornton: barely used at all with a shuma tech dro
06:04 PM jthornton: https://www.mscdirect.com/product/details/50129618\
06:05 PM jthornton: and power feed on X
06:06 PM CaptHindsight: older ones go for $4k
06:07 PM Javabean: drat, its 3 phase... where i am moving i will be lucky to have a stable, steady single phase
06:07 PM jthornton: wow, I don't live in an area that has a lot of machine shops
06:07 PM XXCoder: java you can kinda get around that with some money
06:08 PM XXCoder: large battery packs to cover the unstable power, and convert to 3phase
06:08 PM jthornton: yea you can build a phase converter or change the motor out for a single phase
06:08 PM XXCoder: so output is nice and steady and free from noise
06:08 PM XXCoder: you want clean power for your cnc.
06:08 PM * Javabean cries, 'some money'
06:08 PM XXCoder: indeed
06:08 PM CaptHindsight: Javabean: moving it might be the greatest expense
06:08 PM XXCoder: maybe you can build it out of used car batteries
06:08 PM XXCoder: its supposed to cover dips, not blackout
06:09 PM CaptHindsight: $5k on ebay https://www.ebay.com/itm/Enco-Vertical-Mill-Milling-48-Power-Table-Anilam-DRO-R8-MANY-Extras-2006/174025320149
06:09 PM Javabean: piece by paycheck the house will get "off-grid" power solutions... so i will probably MAKE a bunch of lead-acid batteries
06:10 PM XXCoder: good wind? have water river near you?
06:11 PM jthornton: hmm if I can find that first phase converter I build I'll add that to the deal to sweeten the pot a bit
06:11 PM Javabean: good wind, decent light... 65+mph gusts tho
06:12 PM XXCoder: wind power could be a way to go.
06:12 PM Javabean: just so we are on the same page, jthornton, i wasn't lieing about the price... that is literally all i could come up with at such short notices
06:12 PM XXCoder: you could build one using dc motor converted to be dyinmo
06:13 PM jthornton: easy to make a self starting phase converter from an old 3 phase motor, some caps and a potential relay
06:14 PM jthornton: CaptHindsight, I should haul it up north lol
06:14 PM CaptHindsight: yes, really depends on the area
06:15 PM CaptHindsight: somehow there are still tons of machine shops in this area
06:15 PM jthornton: I have too many projects, I just need to find a local buyer
06:15 PM CaptHindsight: if you're not in a hurry, post it and wait
06:16 PM Javabean: xxcoder, don't know how easy it would be for me to find decent "used" motors in my area... Elpaso/Ft. Bliss Texas(Far west texas)
06:16 PM XXCoder: good question. theres stuff talking about car alternators but from what I understand its crappy
06:16 PM jthornton: usually there are motor repair shops that have some with mangled shafts etc
06:17 PM jthornton: Javabean, take you two days to drive to me in Swamp East Missouri lol
06:17 PM Javabean: last time i asked about getting a motor rebuilt for the "boss", they send things out of town
06:17 PM Javabean: 2 days? it takes a day to get to dallas from here
06:20 PM roycroft: machine shops are shutting down much faster than new ones are starting up here
06:20 PM roycroft: but we still have a few
06:20 PM roycroft: probably exactly enough
06:20 PM CaptHindsight: roycroft: yes, i doubt there have been any news ones around here in ages
06:20 PM CaptHindsight: tool and die used to be just about everywhere around here
06:22 PM jymmmm: power s finally back
06:22 PM jthornton: and another day to Poplar Bluff Mo
06:23 PM jthornton: local plastic injection place used to make a lot of molds but most are made in China now but the don't work when they get here lol
06:25 PM drdoc: Javabean: I did talk to a lawyer, and got the expected answer
06:25 PM CaptHindsight: hey but it was cheap
06:26 PM CaptHindsight: jymmmm: how long were you out this time?
06:26 PM drdoc: I could likely win a judgment against the storage facility, and it would cost more in time & money than I'd recover
06:26 PM CaptHindsight: jthornton: most of the plastic injection shops around here have their own in house tool makers
06:27 PM jthornton: yea but the molds are owned by the customers so they dictate where they are made
06:27 PM Javabean: sorry to hear that, drdoc ... i was only trying to help with ideas, that kind of loss would hurt most people
06:28 PM drdoc: it hurt like hell
06:28 PM drdoc: financially as well as emotionally
06:29 PM drdoc: a lot of the electronics & computer gear was marked for sale, as I had time to do that
06:30 PM * drdoc waits not-very-patiently for the printer bed to cool
06:31 PM Javabean: sorry for you loss, but no one should have to deal with that!
06:32 PM drdoc: except for my great-granddad's anvil and a few keepsakes of my youngest son, it was all just Stuff
06:33 PM drdoc: I learned a very long time ago that if you can't walk away from your belongings, it's not *you* that owns *them*
06:33 PM drdoc: ...which doesn't mean that I handled it gracefully at all.
06:33 PM Javabean: never try to say that "losing Stuff" can't hurt you. gathering it all costs the most expensive commodity humanity has
06:33 PM drdoc: yup
06:34 PM drdoc: at the same time, for me the getting and gathering is a good part of the joy
06:34 PM * jthornton wanders upstairs to retire for the night and get some chow
06:35 PM * drdoc checks the bed temp again
06:35 PM Tom_L: l8r
06:48 PM _unreal_: there made some more good progress on my daughters mini cnc machine
06:48 PM _unreal_: got 90% of the wires run
06:49 PM XXCoder: :)
07:54 PM * Javabean finally discovered co2 fire extinguishers for sale.... wonders if it would be cheaper to replace the electronics in a laser cutter, or get a co2 extinguisher
07:58 PM Elmo40: do both!
07:58 PM Elmo40: it is only money...
08:54 PM _unreal_: XXCoder, sup
08:59 PM Elmo40: moo?
09:15 PM XXCoder: not a lot just got home
09:23 PM Javabean: home is where you keep your cnc
09:23 PM XXCoder: I keep my stuff at
09:26 PM Javabean: ipv4?? dude! the aughty's called, they said support for win2kpro ended years ago...its time to upgrade
09:28 PM XXCoder: lol
09:29 PM XXCoder: shall be always be home
09:30 PM Javabean: meh, DE:AD:BE:EF is a better place for me
09:37 PM _unreal_: hum
09:39 PM _unreal_: https://www.alibaba.com/product-detail/24V-Servo-Drives-for-AGV-Robot_60578341845.html
09:39 PM _unreal_: interesting
09:39 PM _unreal_: $5
09:40 PM XXCoder: 5 dollars? interesting allright since its closed loop.
09:40 PM _unreal_: I have my doubts though
09:41 PM XXCoder: im not sure how it works.
09:41 PM _unreal_: https://www.google.com/imgres?imgurl=https%3A%2F%2Fsc02.alicdn.com%2Fkf%2FHTB1viWyPXXXXXbYapXX760XFXXXe%2F24V-Servo-Drives-for-AGV-Robot-CAN.png_350x350.png&imgrefurl=https%3A%2F%2Fwww.alibaba.com%2Fproduct-detail%2F24V-Servo-Drives-for-AGV-Robot_60578341845.html&tbnid=XhVPjA4UA50dEM&vet=12ahUKEwimzrqtiY3mAhXUdqwKHQXGC3UQMygBegUIARD2Ag..i&docid=tBtnYtFQbHJvWM&w=350&h=350&q=brushless%20servo%20closed%20loop%20-stepper&ved=2ah

09:41 PM _unreal_: that "link" shows the 5
09:41 PM _unreal_: $5
09:42 PM XXCoder: which end goes to servo?
09:49 PM _unreal_: ahh
09:50 PM _unreal_: green end
09:53 PM _unreal_: XXCoder, are you interesed in my servo things I have on hand or no?
09:53 PM XXCoder: nah
09:53 PM XXCoder: its overkill for my cnc router :_
09:53 PM XXCoder: :)
09:53 PM _unreal_: overkill?
09:53 PM _unreal_: how big is your system?
09:54 PM XXCoder: its a standard 6040
09:54 PM _unreal_: LOL and you think what I have is overkill
09:54 PM _unreal_: those motos are 22oz/in
09:54 PM XXCoder: was thinking large commerical ones
09:54 PM _unreal_: motors
10:08 PM taloot: is mesa cards opensource?
10:08 PM Tom_L: the source is available
10:09 PM Tom_L: the designs aren't that i know of
10:10 PM taloot: i will make similar device to THCAD
10:11 PM fjungclaus1 is now known as fjungclaus
10:11 PM taloot: but for fiber laser
10:11 PM taloot: its reads the voltage throw encoder pins
10:11 PM taloot: laser need acoustic to determine the distannce
10:12 PM taloot: mybe i will be 1st fiber laser build using linuxcnc
10:13 PM taloot: with complete control over the THC
10:14 PM taloot: i will build small python panel to commenucate with rs232 to my laser device (for monitoirng the laser it self
10:16 PM taloot: i will save 4000$ paying for chinese crap system
10:21 PM CaptHindsight: taloot: which fiber laser?
10:22 PM taloot: brand
10:22 PM taloot: raycus 2kw
10:22 PM CaptHindsight: taloot: the VHDL is open in Mesa, not the PCB and schematics
10:24 PM CaptHindsight: multimode CW http://en.raycuslaser.com/view/314.html ?
10:36 PM taloot: C:\Users\taloo\Downloads\Documents\User Guide-Raycus-Single-Module Laser Manual 20181212 .pdf
10:36 PM taloot: this one
10:37 PM taloot: http://en.raycuslaser.com/index/download/id/338.html
10:37 PM taloot: lol sorrry
10:39 PM taloot: so i cant copy or modify the hardware
10:40 PM CaptHindsight: taloot: you can modify the FPGA all you like
10:41 PM taloot: i want to build the device fo acoustic
10:41 PM taloot: thats all
10:41 PM taloot: it will be same as THCAD
10:42 PM CaptHindsight: with an ultrasonic distance ?
10:42 PM CaptHindsight: distance sensor
10:42 PM taloot: yes
10:43 PM taloot: http://sc01.alicdn.com/kf/HTB1Yt4otN1YBuNjy1zcq6zNcXXaC/raytools-bt240s-qbh-cl100-fl125-fiber-laser.jpg
10:45 PM CaptHindsight: you can use the output from an ultrasonic sensor to provide an offset for Z
10:46 PM CaptHindsight: it's not that complicated
10:46 PM taloot: yes
10:46 PM taloot: similar to THC
10:48 PM taloot: its even less complicated than thc it self
10:51 PM taloot: later i will try to implent ATC to change the laser nozzle
11:05 PM CaptHindsight: I use fiber lasers with galvos for sintering
11:09 PM fjungclaus1 is now known as fjungclaus
