02:48 AM travis_farmer: Morning :-)
03:01 AM CloudEvil: hey
03:01 AM travis_farmer: :-)
04:36 AM pere: Anyone understand why the string patched in <URL: http://paste.debian.net/1292221/ > is translatable and passed on to translators? Seem like a waste of translator time to me.
04:42 AM JT-Cave: morning
04:43 AM Tom_L: morning
04:46 AM CloudEvil: The string might always not be spaces in the future in principle.
04:48 AM pere: CloudEvil: how is that relevant. once it is not all spaces, it should be flagged as translatable and given to translators.
07:14 AM travis_farmer: 61F/77F a nice day, after yesterday :-)
08:31 AM JT-Cave: seems I've lost the mesact docs somehow
11:38 AM skunkworks: https://www.youtube.com/shorts/vzy376NQP_U
01:05 PM IAmTheRealBeef is now known as Beef
01:23 PM travis_farmer: i had to laugh at myself... i was probing my machine to get some base values, and they kept growing by a 10-thousandth, and i couldn't figure out why... then it hit me, it is an aluminum machine, and it is expanding from the heat of the shop getting hotter...
01:31 PM Beef: Time to plumb all your frame with tubes from a chiller :b
01:31 PM travis_farmer: or insulate the shop better...
01:42 PM Deejay: hi
02:22 PM CloudEvil: Or remake all your scales in aluminium.
02:22 PM travis_farmer: i have no scales...
02:35 PM acer: sup
02:35 PM acer: ugh.... network connection issues hell
02:37 PM acer: travis_farmer, I would tend to think it would be better to keep the machine "i dont know what it is" inside of an area. to maintain a stable TEMP.
02:38 PM acer: the machine its self is going to create heat on its own. but if you have thermal expansion issues that are noticeable during temp variances. Might be worth thinking about.
02:38 PM travis_farmer: it would be, but given my circumstances, it is not feasable
02:39 PM acer: wish I could work faster on this machine I built :(
02:39 PM acer: got so many stupid life issues slowing me down.
02:39 PM acer is now known as _unreal_
02:40 PM _unreal_: currently my father is number one.
02:40 PM travis_farmer: hey, it has taken me years to get this far
02:40 PM _unreal_: $ covering him. I still dont even understand how he is still alive. 4 years stage 4 cancer. 6 covid shots, dead kidneys. and on and on. and he's still walking around.
02:42 PM _unreal_: So I'm flirting with an idea. I have the drive motor from the old washing machine. ITS bldc based. I'm thinking it would be cool to convert it into a spindle or lathe drive motor.
02:42 PM _unreal_: this is a future project concept
02:42 PM _unreal_: but that motor is STUPID powerful
02:43 PM _unreal_: it would be cool to use it to build maybe an epoxy creat cnc milling machine
02:44 PM _unreal_: or maybe a custom small base high power lathe
02:45 PM _unreal_: years... dont feel bad. My current NEW cnc machine is still 50% build some 4 years later
02:45 PM _unreal_: so many life issues halting me.
02:49 PM travis_farmer: yeah, life issues here too. lost income, but i hope to make some with my machine... soon, i hope
02:51 PM _unreal_: what do you have for a machine?
02:52 PM travis_farmer: 4 foot by 4 foot woodworking router
02:52 PM _unreal_: you should be able to make plenty of money with your machine. I average about $120 a week with my 7.75"x12.75" cnc machine at home.
02:52 PM _unreal_: ........ I hate you
02:52 PM travis_farmer: ...?
02:52 PM _unreal_: bigger
02:53 PM _unreal_: much
02:53 PM _unreal_: as I was saying you can make a good income from it
02:54 PM _unreal_: I would look into inlay cutting boards and other suchs things
02:54 PM _unreal_: ETSY
02:54 PM _unreal_: https://photos.app.goo.gl/1ejmwQjHGskbBvob9 My laster etcher
02:54 PM travis_farmer: yeah, i was thinking signs and plaques too
02:54 PM _unreal_: My cnc machine https://photos.app.goo.gl/CuUszxKaFziVnQKX9
02:55 PM _unreal_: it just takes advertizing and the WILL DESIRE to follow through
02:55 PM _unreal_: those links are just a fraction of what I do
02:56 PM travis_farmer: nice
02:56 PM _unreal_: but just to give you an idea of what you can do. I "do" have a 4x4 machine that I was offered but I cant take it till I escape my father. and I cant escape him till he "recovers" or passes from cancer. till then I'm a $ prisoner :(
02:58 PM travis_farmer: just think of all the money he put into you, growing up ;-)
02:58 PM _unreal_: no he didnt
02:58 PM _unreal_: infact but not to get off topic. he DID put together a 6 digit trust fund. and my mother stole it....
02:59 PM _unreal_: just before I turned 18....
02:59 PM travis_farmer: Hmmm...
02:59 PM _unreal_: oh trust me....... the bs in my past. I hate my entire fam.... I should be worth about half a billion right now.
03:00 PM XXCoder: travis_farmer: I hate that. no matter how much parents paid child on growing up, child do not owe them anything. its parents who bought child into existance.
03:01 PM travis_farmer: Hmmm...
03:01 PM _unreal_: travis_farmer, this is how bad it is..... I'M!!!!! a cast member on a reality TV series
03:01 PM _unreal_: (Yacht kings)
03:01 PM _unreal_: on YT...
03:03 PM _unreal_: lol XXCoder YOU MAKE it sound like we came from the "pound" (parents who bought child into existance.)
03:03 PM _unreal_: hehehee
03:04 PM _unreal_: XXCoder, so the new cnc build. I'm looking at using two DC motors that were the VACUUM pumps for food storage devices..
03:05 PM IAmTheRealBeef is now known as Beef
03:05 PM _unreal_: I'm looking at using them as the positive air supply for the new CNC
03:05 PM _unreal_: they are tiny and use those poly/ceramic pistons
03:07 PM XXCoder: unreal its very generic because there is few ways, from just regular sex to adoption
03:08 PM XXCoder: in all those cases, child certainly couldnt agree to a debt.
03:08 PM XXCoder: now, I have done things to help my mom. out of love, not because I "owe" her.
03:09 PM _unreal_: if I use them as the positive air supply I'll tie them together with a micro controller. and do a 50/50 single POT. where it drives one upto 100% PWM. then starts the second pump up at say? 20-30% PWM and finishes the remaining 0-100% with the second pump. so I can have a more or less 0-100 air supply setup.
03:10 PM _unreal_: 0% would equal one compressor running at ? 20%. 100% output would be both pumps running at 100% pwm. so more or less looking at a 200% " total"
03:12 PM _unreal_: I've done some tests and one pump does a good job with 1/8th line. with a fine tip output. its good to blast away chips AT the milling bit.
03:13 PM _unreal_: so 2 should be "ok" and I could add a mist lub into it.
03:13 PM _unreal_: so I dont load up on "fluid" on the machine
03:14 PM _unreal_: Thats been my number one problem with the small mahcine is chip build up becuase I dont hav e a way to clear chips.
03:14 PM _unreal_: just the dust shoe/vacuum setup. It works but its not a positive air function.
03:20 PM Beef: Would using a collet fan be a solution for you?
03:23 PM Beef: https://wiki.printnc.info/en/mods about halfway down the page there are some cad files for a collet fan - many of the PrintNC guys are using them just 3d printed out of PLA and there's a few other variations floating around for various RPM ranges
03:27 PM XXCoder: cpap style compressor fan might work but would it blow hard enough dunno
03:32 PM IAmTheRealBeef is now known as Beef
03:43 PM _unreal_: colllet fan. naaa not on my setup. and I'm not a fan of those in general
03:43 PM _unreal_: i'm not saying they are wrong. but milling aluminum :S
03:44 PM _unreal_: or fiber material. I would be fearful that the dust collector didnt capture everything. and I'd be filling the room with particles
03:52 PM Beef: I have had good luck milling aluminum and steel with these on my router as I have no coolant setup (yet), but enclosure or dust evacuation is certainly good. I wear a respirator when cutting without enclosure anyway and a dustshoe for wood. I have filters over the fans for electronics enclosure and PC so it's a non-issue there as well.
03:53 PM Beef: It's just a low-cost option. Another possible option (without understanding your machine) is to use a sump pump as a low-cost flood coolant system, just make sure to filter the coolant before it recirculates
03:57 PM Beef: Otherwise wouldn't air blast or mql (even just the cutter) throw aluminum dust around too? around unless you have a more VMC style machine that takes big bites
03:58 PM _unreal_: my new bigger machine will have a high power vacuum setup
03:59 PM XXCoder: if youre making dust you should adjust feed, as that is a lot of rubbing and tool wear
03:59 PM XXCoder: unless its finish cut of course
03:59 PM _unreal_: the goal is to use a needle style setup to shoot a fine stream of compressed air at a fine location. the idea is to clear material with out high volume that way the vacuum has less less
03:59 PM _unreal_: XXCoder, depends on the material cutting
04:00 PM XXCoder: im talking about alum of course as its the material beef is menioning
04:00 PM _unreal_: a number of materials I cut I have to use rotary rasps
04:00 PM Beef: Yeah that's exactly right anyway - you will get your dust mostly on finishing ops
04:01 PM _unreal_: aluminum on my smallmachine I typically use 2 flute upcut bits
04:01 PM _unreal_: I get small sliver chips
04:01 PM _unreal_: but again that has to do with feed/speed
04:01 PM _unreal_: that machine is not a high power machine
04:01 PM _unreal_: flex is an issue
04:01 PM Beef: I mostly am a pro at managing chipwelding ... my record so far is managing to chipweld and snap 10mm 3f in my router
04:02 PM _unreal_: the new machine should be "SHOULD" be less prone to flex
04:02 PM Beef: </3
04:02 PM Beef: What sort of design are you doing _unreal_?
04:02 PM _unreal_: moving gantry
04:02 PM _unreal_: about 30x20" work area
04:02 PM _unreal_: and plunge of upto 8""
04:02 PM Beef: 8"!
04:03 PM Beef: I hope it's extra beefy because that's a lot of Z for a moving gantry
04:03 PM Beef: oh wait, sorry, I did the conversion in my head wrong
04:03 PM Beef: It's on the larger end but I was thinking like 400mm not 200 and should be fine
04:04 PM Beef: moving rail or moving carriages for Z?
04:04 PM _unreal_: moving carriage
04:05 PM _unreal_: I have 15mm aluminum plate with rails on it
04:05 PM _unreal_: fixed to the X axis on rails
04:05 PM Beef: should be fine then
04:06 PM _unreal_: the x rails are aluminum extrusion 20x40
04:06 PM _unreal_: and if I run into any flex issues I can always tack on more support to the back side of the rail to stiffin
04:06 PM _unreal_: 0 or all the way down with have the greatest load
04:07 PM _unreal_: rotation load
04:07 PM Beef: can your existing router manage steel? I would rather use steel than alu extrusion if I could help it - or one of the vallder extrusions
04:07 PM _unreal_: no
04:07 PM _unreal_: as I said I can always mount extra support
04:07 PM _unreal_: the back side of the X/Z axis is open
04:07 PM _unreal_: so adding secondary support is not na issue
04:07 PM Beef: yeah - I just say because I have 150x150x5 gantry and even I get flex on it - although it's 1.2m span moving gantry
04:08 PM Beef: steel*
04:08 PM _unreal_: it has a 1.5kw spindle
04:08 PM _unreal_: but the goal is not to be running high load on it
04:10 PM Beef: It'll work well anyway - I would suggest one of the 2.2kw spindles if you can manage it just to get the ER20 collets instead of ER11 - there's some 8mm and 10mm insert mills that you can use to run PCD or other inserts for some nice surface finishes
04:10 PM Beef: but if you already have the spindle then I wouldn't worry about it
04:12 PM _unreal_: lol
04:12 PM _unreal_: I have a 2.2kw but I dont have the machine for it
04:12 PM _unreal_: I got it 2 years ago before the prices went crazy
04:13 PM * travis_farmer has a 4.5KW ATC on his ;-) :-p
04:13 PM _unreal_: I got a whole bunch of stuff. but some how my father is still hanging on. so till I escape my fanatical HELL I cant do much.
04:13 PM Beef: I need the gif of the cat smashing the table with "WANT" - I have only 3kw 2pole at the moment but I'd like to get a larger 4pole after I manage to kill this one off
04:14 PM Beef: oof
04:14 PM _unreal_: I purchased most of the parts to build a 4x4' then I was offered a working machine mothballed in storage....
04:14 PM _unreal_: cant do anything till again last tatement
04:15 PM _unreal_: statement
04:15 PM Beef: understand
04:15 PM travis_farmer: i know, i was just poking a nerve ;-)
04:15 PM Beef: But about prices ... here in PL I'm paying about 1.5euro / kWh right now and would love to do servos and a larger spindle but I think I will run out of money paying the electric bill first
04:16 PM Beef: I have large steppers for now but they are more power efficient than equivalent servos (Moving gantry is about 150kgish) although it limits my max rapids to ~10k mm/min
04:17 PM acer: pl poland?
04:17 PM Beef: yeah
04:17 PM acer: and freaking hell my internet kicked out again
04:17 PM travis_farmer: says your still here ;-)
04:17 PM Beef: you're all still here in my heart <3
04:17 PM acer: * Disconnected (No such device or address)
04:17 PM acer: * _unreal_ is already in use. Retrying with unreal...
04:18 PM XXCoder: travis it takes time for server to time out on ping and remove nick
04:18 PM travis_farmer: i know, XX. i was poking a nerve again ;-)
04:19 PM Beef: travis what kind of machine do you have that nice atc on? and ISO or BT or something else?
04:19 PM acer: I could fix the issue in a heart beat but again. I'm stuck living at my fathers house AIDING HIM in his health crisis. and I'm not allowed to fix the internet. I have a nice POE wifi range extender that could give the entire house good internet. NOOOOOOO cant do that. I may not be as secure as his broke ass router that even the internet company said is likely infected with something and chewing random bandwidth.
04:19 PM travis_farmer: 4 foot by 4 foot woodworking router (Techno/ISEL)
04:20 PM acer: I have all kinds of BLDC motors
04:20 PM acer: they are all likely better for 3d printers or laser cutter/etchers.
04:20 PM Beef: looks nice Travis, but it's cheating in my book if you didn't DIY it and you're running LCNC
04:20 PM Beef: lol
04:21 PM acer: all of them are nema23
04:21 PM travis_farmer: i bought it as just the machine. all electronics are mine and Mesa
04:21 PM Beef: It counts then
04:22 PM acer: kills me but I'm starting to pull apart the original lcnc box I built. the mesa drive I need to drive other motor drivers I build. I built the ve7it servo drivers. but I've never gotten them fully working. not sure why and I had some issues as well that my have messed them up? dont know
04:23 PM acer: in any case only the mesa can drive them.
04:23 PM acer: has to do with featured outputs
04:23 PM Beef: featured outputs?
04:23 PM acer: step/dir vs quadrature output
04:23 PM Beef: ah
04:23 PM acer: the drivers take quadrature drive input
04:24 PM acer: instead of step/dir
04:24 PM acer: wish it was step/dir
04:24 PM acer: but thats not how it was coded
04:24 PM acer: put a lot of time and money into it. then I ran into fam issues
04:24 PM acer: my fathers health
04:25 PM Beef: yeah family issues aren't fun - and in poor health people can get more difficult to deal with which is pretty tough
04:25 PM acer: so again. I'm stuck on a lot of projects till I can get way. Kills me I should be making about 100-200k $ a year but I'm making just shy of 100k becuase I'm "here" and broke paying for him :(
04:25 PM acer: extreamly
04:26 PM Beef: lol I'm making about 19k/yr right now
04:26 PM travis_farmer: i made just 11K this year...
04:26 PM acer: I played with the chat GPT the other day and CODING.... :) i CAN GET USE TO THAT. I just wrote a bunch of complex code testing it. and they worked flawless
04:26 PM acer: o,O
04:27 PM Beef: I've found that chatgpt is ok at writing code, but it's great at debugging or rewriting sections
04:27 PM acer: granted I am in the luxuy yacht business but you can really blow it away with online stuff
04:28 PM Beef: I manage a dental lab but we're still small at the moment + dental is too cheap to make much money. In the process of learning RPA so we can speed things up some and stand out more
04:28 PM acer: dental lab?
04:29 PM acer: I'm not sure what a dental lab dose
04:29 PM acer: does
04:29 PM Beef: manufacturing dentures / crowns / bridges etc
04:29 PM acer: I use to be a nurse, a med tech. and before that I did bio med research for year decade
04:29 PM Beef: the dentist wants you to think they do but but they have no idea how lol
04:29 PM acer: ahh
04:29 PM Beef: (well ok some do of course)
04:29 PM acer: so 5 axis mfg
04:30 PM acer: making molds, and doing pour casting? or straight 5 axis milling
04:30 PM Beef: our lab we're doing almost all injection molding actually since we focus on polymer dentures with acrylic or composite teeth
04:30 PM acer: but what is the design created from?
04:30 PM acer: 3d print? or 5 axis milled?
04:31 PM acer: laser cintered mold to be injection molded?
04:31 PM Beef: by hand out of wax lol - we'll pick up a 5 axis mill down the road and get into zirconia/lithium disilicate and experimenting with some wax stuff, but 3d printed is actually more time consuming to get done well
04:33 PM Beef: either you have to bake out a 3d printed resin that sublimates (time consuming and lots of electricity cost) or you have the difficulty of machining wax (also needed baked out or it needs to be low-temp enough that it's hard to machine)
04:34 PM Beef: I have some prototypes for equipment that will solve this problem, but it's a long R&D until we make enough money with the main business, and it may not get anywhere
04:35 PM acer: I would look at one of the mini 5 axis cnc machines
04:35 PM Beef: there are specialized 5x for dental machining that will automatically load/remove pucks of zirconia so you can do unattended machining
04:36 PM acer: this one https://wiki.imal.org/sites/default/files/img_0051_w_0.jpg
04:37 PM acer: that machine you can create a center mount jig to hold 4 wax blocks
04:37 PM Beef: I've seen pocketNC before - considered to make one - but for business its worth buying with warranty/good controls/service
04:38 PM Beef: https://www.rolanddga.com/products/dental/dwx-52dci-5-axis-dental-mill-with-automatic-disc-changer probably won't go roland, but these kind are better suited for the type of work
04:48 PM IAmTheRealBeef is now known as Beef
05:41 PM solarwind: NEMA 17 size is so cute
06:18 PM Unterhaus_ is now known as Unterhausen
06:19 PM Unterhausen: I have some nema 17 servo motors. I really wish I knew how to drive them
06:29 PM solarwind: CaptHindsight, any idea where I can get a monocrystalline diamond turning tool? I want to see what my lathe can do
06:29 PM solarwind: Unterhausen any BLDC servo drive
06:30 PM Unterhausen: I doubt it's quite that easy
06:30 PM solarwind: it really is
06:30 PM solarwind: I bought so many random servos off of kijiji/ebay for $10 whose datasheets don't seem to exist
06:30 PM solarwind: THey have a label on them with the wattage rating. Just spend 10 minutes figuring out the approximate current/voltage
06:30 PM solarwind: They all have 3 wires for the 3 phases, and an encoder
06:31 PM solarwind: For older servo motors, the encoder almost always outputs a differential quadrature signal you can see on an oscilloscope
06:31 PM solarwind: I have 20 different ones, they _ALL_ behave this way
06:32 PM solarwind: use the oscilloscope and logic analyzer or even a microcontroller to figure out the encoder counts/revolution. Just enter these parameters into a decent general-purpose servo drive like the Odrive, or something from Elmo motion control or whatever
06:33 PM solarwind: Unterhausen a bit of fiddling with the servo drive and all of them work
06:34 PM solarwind: I've never seen a servo motor that's any different, other than the modern ones which use serial protocols for their high speed high resolution encoders. But it's not encrypted or anything, just takes 10 minutes with an oscilloscope to reverse engineer the protocol
06:35 PM IAmTheRealBeef is now known as Beef
06:35 PM solarwind: And then program an FPGA to translate that into something your servo drive can understand like AB quadrature signals or whatever. But none of my used servos from ebay/kijiji do that since they're all pulls from old industrial equipment, more than 20 years old
06:36 PM Beef: solarwind Check out Alibaba for inexpensive MCD - they're not quite as good but can be had for like 80-120 bucks
06:36 PM solarwind: Message me if you want help with yours
06:36 PM solarwind: Beef thanks. I just want to turn some lenses for my flashlights. Don't need vision quality optics
06:37 PM Beef: Yeah - as I said it's not as nice as name brand stuff, but also they're not in the same ballpark for price. AliExpress doesn't generally have them but they do have a lot of PCD
06:38 PM solarwind: That should be fine too
06:39 PM Beef: MCD finish is so much better in aluminum than PCD so I assume its the same with whatever material you're turning for optics. I mostly to milling on router not lathe-ing but with good tram you can get legit mirrors
06:39 PM Beef: do*
06:40 PM solarwind: glass
06:40 PM Beef: On a related tangent ... how much of a flashlight nerd are you?
06:41 PM solarwind: well I'm in ##flashlight
06:41 PM solarwind: and have over 20 of them
06:41 PM solarwind: but how much of a nerd can you be? Just know your LEDs lol
06:41 PM Beef: 20 you're still in the realm of sanity
06:41 PM solarwind: it's just a battery, constant current source, and emitter(s)
06:41 PM Beef: oh boy
06:41 PM Beef: When I was living in the States I bought 3 flashlights off PFlexPro - this was like 8 or 9 years ago - he did custom lights
06:41 PM solarwind: Yeah I'm going to turn my own
06:42 PM Beef: and they have a whole 4 page manual on how to program them using the tailswitch
06:42 PM solarwind: no need to compromise
06:42 PM solarwind: Don't need to be an idiot with the programming either
06:42 PM solarwind: I can just program it via the computer once
06:43 PM Beef: honestly? I wouldn't get a flashlight without it anymore because you can re-configure it a bit for say hiking use or putting on a rifle or working on a car because you want different brightness profiles for each
06:43 PM solarwind: whatever zebralight does is more than enough for me
06:44 PM solarwind: I'm not outdoorsy to that extent, so I'm always within range of a computer
06:44 PM solarwind: Beef on your monocrystalline router thing, what kind of tool is it?
06:44 PM solarwind: And how are you getting mirror finishes?
06:46 PM Beef: it's not on my router - I am getting almost as-good finishes with PCD but haven't picked up MCD yet, but one of my buddies from PrintNC has. I'll drop into imgur
06:46 PM solarwind: That would be awesome, thanks. I'm really interested in that
06:51 PM Beef: https://imgur.com/a/D2WALYj solarwind
06:52 PM Beef: You can still lightly see the tooling marks he's got in the photo of the alu, but it's mirror like in my book
06:54 PM Beef: https://imgur.com/a/r6ac61g here's my finish for comparison. If you freeze frame it you can see my tram isn't quite as good as the reflections are slightly warped
06:57 PM acer: what is the linuxcnc pastebin link?
06:58 PM Beef: Not long after this I had to move the machine and while I had it apart I added another 400kg to the machine in extra crossmembers and grout filling (for damping). I haven't finished tramming the machine yet, just got it running last week but then went on a 4 day hiking trip but it sounds *way* better in steel when I did a quick facing test
06:59 PM Beef: I need to add a steel baseboard (because I have OSB for now) but the 15mm plate I'd like to use isn't gonna be cheap so I gotta save up for that for a bit
07:00 PM acer: What do you guys think?
07:00 PM acer: https://pastebin.com/xCqVpJJm
07:02 PM Beef: this is for arduino to control your two air blast circuits with pwm, right?
07:02 PM acer: the goal is to use an attiny85 to control two PWM outputs. control them in series with analog input 0-100 = pwm1 0-100, pwm2 100-200
07:02 PM acer: right
07:03 PM acer: run one 20%-100% pwm output when over 51% analog input start the second one at 20% and "0-100% output it constrain 20%-100% output = input 0-100 working range per each pwm
07:05 PM acer: so analog input 0-50 pwm one goes 0 to 100 output, then at analog input 51% pwm1 stays on at 100% and pwm2 starts at its 0-100 range just like pwm1
07:05 PM acer: and I added soft start and enable/disable
07:06 PM acer: thoughs? its only concept code I have not even tested it
07:06 PM Beef: looks fine to me - I would hook it to a couple of LEDs with resistors and double-check but it seems like it will work
07:07 PM Beef: you may want to drive some kind of status output - whether LED or a 9 segment display or one of the cheap LCDs or something, to give you some feedback on what the value is
07:07 PM acer: the goal is to use two MOS MODULES. that are used to drive LASERs with pwm.
07:07 PM acer: why?
07:07 PM Beef: if you find a value you like, you can hit it more consistently
07:07 PM acer: the idea is to have a big POT nob with a 0-100
07:08 PM acer: over kill. not wrong but over kill
07:08 PM Beef: fair
07:08 PM acer: I wrote that code with chat GPT
07:09 PM Beef: i like those LCD modules for arduinos ... maybe because they light up and I'm probably a flashlight nerd
07:09 PM acer: not enough I/O using the ATTINY85
07:09 PM acer: maybe an i2c lcd but again. why
07:09 PM Beef: i'm impressed with the code then - its simple sure but it should run anyway
07:10 PM acer: I SUCK at coding
07:10 PM acer: Beef, this is what I used https://pastebin.com/UdH13Mg0
07:11 PM Beef: me too, but if you chip away at it you can solve anything
07:12 PM Beef: that's a good clear description
07:12 PM Beef: if you broke this list out into comments for your code you could fill each code block as you go along ... it's how I wrote my first graphics shader in HLSL during coronavirus when i was first learning to code
07:13 PM Beef: i tried recently when refactoring my code to add some more features for a newer version to see if chatgpt could help at all and absofuckinglutely not, it was terrible output and I was definitely faster to do it myself
07:13 PM Beef: was great at adding in extra comments for code that I forgot what it did though and it was generally pretty spot on
07:16 PM acer: beef I could be wrong but I think it has the input backwards for the enable disable
07:16 PM acer: enable should be high. and disable should be pull down low
07:16 PM Beef: I didn't look that deeply
07:17 PM Beef: just test your outputs with some LEDs because you'll see them PWM properly
07:17 PM acer: I do need to test it. but I need to setup the hardware first
07:17 PM Beef: also there's something to keep in mind when using MOSFETs and having separate voltages for input and the switched signal that I forget that I had to keep in mind
07:18 PM Beef: I did a PID controller for heating an end effector and it used the 5v off arduino to control 4 60w 24v 3d printer heaters
07:19 PM Beef: turns out that it wasn't enough heating to be as fast as I liked but it still worked ok
07:19 PM acer: maybe..
07:19 PM acer: I'll find out when I cross that bridge
07:19 PM Beef: i have the writeup one moment
07:20 PM acer: I dont know if would be better to run both motors in parallel. or in series
07:20 PM Beef: actually no I misremembered - I had tried to use the MOSFETs but I didn't figure it out
07:21 PM acer: I figure series because that one one mini compressor gets the most ussage
07:21 PM Beef: because it was due the next day and i was having issues because the power supply was shutting off from sensing a short
07:21 PM Beef: ended up using a relay
07:21 PM acer: but then again I may find that I'm running both at 100% at which point heeheheh
07:22 PM solarwind: That is excellent
07:23 PM acer: solarwind, ?
07:23 PM solarwind: I wonder what I can do with a fly cutter with a diamond tip
07:23 PM Beef: i mean once you have mirror you can't get any better
07:23 PM Beef: you won't get like atomically flat surface lmao
07:24 PM solarwind: Of course, that's not what I'm expecting at all
07:24 PM solarwind: I just mean in comparison to high speed steel
07:24 PM Beef: I mean, outside of its use cases for particular special cutters or getting just the right fit, there's many things better than HSS these days
07:40 PM CloudEvil: There are many grades of 'mirror'
09:27 PM Tom_L: JT-Cave, PR #27 is up
09:34 PM Tom_L: also, Startup tab -> Enable Firmware Tools doesn't save or doesn't load... either way it's unchecked after a save
10:28 PM acer: anyone big on coding arduino? https://pastebin.com/dKXUKYKF https://pastebin.com/hVDZi0UG
