03:22 AM lcnc-relay: <Travis Farmer@> Morning
03:29 AM rmu: mornin
04:25 AM Tom_L: morning
05:57 AM -!- #linuxcnc mode set to +v by ChanServ
06:58 AM rdtsc-w: the grandkid (just started school) just the other day said "six seven skibidi brainrot." Uhhhhhhh what? lol
08:07 AM lcnc-relay: <skunkworks@> dad use to use 60-40 in the same way 6-7 is being used..
08:07 AM lcnc-relay: <skunkworks@> (the tin/lead content of common solder)
08:55 AM lcnc-relay: <Lesliet@> good timezone
08:55 AM lcnc-relay: <Lesliet@> ah yes. Skibidi brainrot
08:58 AM -!- #linuxcnc mode set to +v by ChanServ
08:59 AM lcnc-relay: <Lesliet@> gotta get the old drum kit cleaned up and listed for sale this weekend; hoping to get enough to cover my servos
09:00 AM lcnc-relay: <Lesliet@> been thinking it might be interesting to play with LinuxCnc for my lathe, too, kinda wondering if I could set up something that gives the ELS functionality without too much fumbling for speeds and feeds
09:01 AM lcnc-relay: <Lesliet@> eg, the leadscrew is run by a servo, but the crossfeed isn't. (maybe someday, but not yet)
09:02 AM JT-Shop: Electrophoretic Light Scattering?
09:02 AM lcnc-relay: <Lesliet@> electronic leadscrew
09:02 AM lcnc-relay: <Lesliet@> it has the Clough42 conversion
09:02 AM lcnc-relay: <Lesliet@> a little too easy to overload the servo, though
09:03 AM lcnc-relay: <Lesliet@> so I may need to upgrade that
09:03 AM lcnc-relay: <Lesliet@> it's running a hybrid stepper with the control electronics as part of the stepper
09:05 AM lcnc-relay: <9ꌗ ❖ ravaged skies@> Lesliet@: That guy is a clown
09:05 AM lcnc-relay: <9ꌗ ❖ ravaged skies@> I mean he’s alright but he doesn’t know a lot of things, especially about servo drives
09:06 AM lcnc-relay: <9ꌗ ❖ ravaged skies@> His electronic leadscrew is a shitshow
09:06 AM lcnc-relay: <Lesliet@> eh, I'm not exactly a pro either. Just continuing to learn new stuff
09:10 AM lcnc-relay: <Lesliet@> I figure my knowledge of coding is approximately like a pimple on the ass of most of the folks in here, so I'm not in a position to talk smack about anyone.
09:12 AM lcnc-relay: <9ꌗ ❖ ravaged skies@> Use a nice leadshine ethercat servo kit and a ball screw. They’re not that expensive.
09:12 AM lcnc-relay: If you’re on a budget, get a stepperonline.com T6 step/dir interface servo (they’re rebranded leadshine)
09:12 AM lcnc-relay: 750W is plenty.
09:12 AM lcnc-relay: <9ꌗ ❖ ravaged skies@> Lesliet@: But I am. And I often do because I can’t stand incompetence.
09:16 AM lcnc-relay: <Lesliet@> a ballscrew might be challenging to implement on a 60's vintage Craftsman lathe. Not impossible, but it would require changing a lot of basic function of a manual machine
09:16 AM lcnc-relay: <Lesliet@> the other project is a Bridgeport R2E4, which already has ballscrews, and is getting AC servos
09:16 AM lcnc-relay: <9ꌗ ❖ ravaged skies@> Replace the leadscrew with a Ball screw
09:17 AM lcnc-relay: <9ꌗ ❖ ravaged skies@> You can gut all the mechanical bits
09:18 AM lcnc-relay: <Lesliet@> 9ꌗ ❖ ravaged skies@: what I mean, is I'd be giving up using the halfnut and feed lever, and would need to control carriage motion through more of a CNC interface. On this machine, I don't really want to go full cnc, I just don't like change gears
09:18 AM lcnc-relay: <9ꌗ ❖ ravaged skies@> All you need to do is attach the ball nut to the carriage
09:18 AM lcnc-relay: <9ꌗ ❖ ravaged skies@> You can remove all hardware related to threading, engaging disengage auto feed etc
09:18 AM lcnc-relay: <9ꌗ ❖ ravaged skies@> Lesliet@: Yes exactly that’s the point
09:19 AM lcnc-relay: <9ꌗ ❖ ravaged skies@> Then you can replace it with a manual pulse generator and gain insane precision
09:19 AM lcnc-relay: <9ꌗ ❖ ravaged skies@> You do lose tactile feedback. That’s the one and only downside
09:19 AM lcnc-relay: <Lesliet@> (heading off for work)
09:19 AM lcnc-relay: <9ꌗ ❖ ravaged skies@> Everything else is a major advantage and you don’t need any CNC interface
09:20 AM lcnc-relay: <9ꌗ ❖ ravaged skies@> Think of it like fly by wire
09:20 AM lcnc-relay: <9ꌗ ❖ ravaged skies@> Actually it is the exact definition of a fly by wire system lol
09:22 AM lcnc-relay: <9ꌗ ❖ ravaged skies@> On another note my forklift main cylinder is slightly leaking. It’s a 3 stage telescopic mast and it’s dripping some oil out the top when under load
09:23 AM lcnc-relay: <9ꌗ ❖ ravaged skies@> I don’t know for sure but I’m guessing it’s a displacement cylinder so all the seals should be on the top. At least I really hope it is. If it’s a piston type cylinder, replacing piston seals is going to suck
10:03 AM roycroft: grr, my parcel is being held by customs for an incomplete commercial invoice
10:03 AM roycroft: and the shipper is japanese and does not speak english
10:04 AM roycroft: i'm having a hard time explaining the problem
10:05 AM roycroft: this is not the problem i expected, as it has nothing to do with tariffs (yet)
10:42 AM roycroft: if any of you know anything about this, is it possible for me to complete the commercial invoice in lieu of the shipper's doing so?
10:47 AM lcnc-relay: <skunkworks@> I don't know enough about it. We do commercial invoices out-going..
10:47 AM lcnc-relay: <skunkworks@> (mostly to canada and mexico - but sometimes to other countries)
10:52 AM roycroft: i've done so as well
10:53 AM roycroft: but i always make sure to complete the paperwork properly, and i've never had a problem
10:53 AM roycroft: i've never had to deal with incomplete paperwork on an import
10:53 AM roycroft: i hope this gets sorted, and soon
10:54 AM roycroft: it's an expensive item, and if things go well i'll be purchasing several others from that vendor
10:55 AM roycroft: if they don't i'm not sure what i'll do
10:55 AM roycroft: not many japanese tool stores ship to the us
10:56 AM roycroft: this one does, and has a reputation for doing so, which makes me wonder how/why they did not complete the paperwork properly
10:56 AM roycroft: they should know what to do, unless the requirements have changed recently
10:57 AM roycroft: the current regime seems to be good at making random changes and not telling people
11:32 AM roycroft: i was just informed that if the parcel does not clear customs and is returned to the shipper, i still have to pay duty and tariff on it because it arrived in the us
01:53 PM xxcoder: fun. I had to pull off bottom part of skylight because it was super humid for some reason. cleaned it up and gave it little bit isulation upgrade
02:03 PM lcnc-relay: <skunkworks@> now it isn't a sky light?
02:04 PM xxcoder: it still is.
02:05 PM xxcoder: I added another arylic panel so its dual glass, and plastic sides is covered now
02:05 PM xxcoder: its not a huge upgrade but good enough
02:05 PM xxcoder: it should be better on being sealed too
02:11 PM xxcoder: before you ask yes theres small gap between glasses lol
02:35 PM Unterhaus_ is now known as Unterhausen
04:23 PM xxcoder: https://youtu.be/oj6uFWOuFMM
04:23 PM xxcoder: pretty amazing. 3d printing with fibre inbuilt
04:23 PM xxcoder: not just with filament, but in specific design you put in.
04:38 PM lcnc-relay: <Lucid Nonsense@> https://www.linkedin.com/posts/adafruit_opensource-privacy-techpolicy-activity-7396903362237054976-r14H
04:40 PM lcnc-relay: <Lucid Nonsense@> Qualcomm seems to have far exceeded my pessimistic expectations and drilled to the deepest depths
04:44 PM -!- #linuxcnc mode set to +v by ChanServ
04:51 PM lcnc-relay: <alex.w#18266@> xxcoder: Isn't that similar to markforged?
04:52 PM xxcoder: pretty sure difference is this new one is much cheaper
04:52 PM lcnc-relay: <alex.w#18266@> They have two print heads, one for plastic, one for fiber, so they can lay down CF layers to get continious CF
04:52 PM lcnc-relay: <alex.w#18266@> Ah, there is certainly a market to fix the pricing of that printer
05:03 PM _unreal_: ve7it, I've been going over the boards trying to ensure there are no chances for problems.
05:03 PM _unreal_: and no errors
05:06 PM _unreal_: interesting I logged out at 9:50am?
05:07 PM _unreal_: I wonder what happened because my computer was off when I got home. dont know if it was a power loss or something else
05:35 PM lcnc-relay: <Lucid Nonsense@> It's really hard to overstate what a disaster this is for open source and the maker movement, I'd take it so far as to say it would be irresponsible to auggest anyone download any new arduino ide from now on
05:36 PM lcnc-relay: <Lucid Nonsense@> Suggest
05:36 PM lcnc-relay: <Lesliet@> looking at that article, I would agree
05:36 PM xxcoder: was uncertain what you meant, so went over to discord and see your quoted link
05:37 PM xxcoder: dang thats not good at akk
05:37 PM xxcoder: ll
05:38 PM lcnc-relay: <Lesliet@> the eula bursts into flames after you sign it, and your soul immediately leaves your body
05:38 PM roycroft: so when is the arduino replacement going to be released?
05:38 PM roycroft: an rpi can do what an arduino does, albeit for a bit more money
05:39 PM roycroft: but it should be fairly straightforward to engineer something more equivalent to an arduino
05:39 PM lcnc-relay: <Lesliet@> does seem like a cycle that repeats, though. Cool open source people make something that everyone can use, it takes off, good times for some years. Then EvilCorp.com acquires it, and does evil stuff, as usual.
05:40 PM lcnc-relay: <Lucid Nonsense@> It's not just arduino, it's the endless examples other microcontroller code that uses the arduino ide and compiler for things likr esp32 and stm32
05:43 PM lcnc-relay: <Lucid Nonsense@> Problem is, there are probably tons of reasons why these terms violate existing open source agreements and are effectively illegal, but they're so rich no one's going to take them on and win
05:43 PM xxcoder: theres always winningnsharing scheme for affording a lawyer
05:44 PM xxcoder: its not amazing, but much better than infinity cant do it
05:44 PM roycroft: i think it's not news to anyone here who knows me at all, but i am not in any way opposed to free markets and profitibility
05:44 PM roycroft: but they need to be fair markets
05:45 PM roycroft: and the economy in this country is not at all fair
05:45 PM roycroft: the megacorporations can do whatever they want
05:45 PM roycroft: and they can sue anyone who opposes them into oblivion
05:46 PM roycroft: there is room for a fair, profitable market and a community-driven not-for-profit market to coincide
05:46 PM roycroft: it does not have to be one or the other
05:46 PM lcnc-relay: <Lucid Nonsense@> That's not freedom, it's neo feudalism
05:46 PM roycroft: it can be both
05:47 PM roycroft: "the wealth of nations" is literally the first book in my library
05:47 PM roycroft: i use the library of congress cataloging system, and the call number of that book is ac1.s64
05:48 PM roycroft: i am quite familiar with it
05:48 PM roycroft: the book is exactly 900 pages long, plus appendices and index
05:48 PM roycroft: in exactly one place is the term "the invisible hand" used
05:49 PM roycroft: the phrase that the laissez-faire capitalists quote as their justification for doing whatever they want without regard for morality/ethics
05:50 PM roycroft: the other 899 pages+ of smith's book discusses how government needs to put constraints on the invisible hand to keep it fair and not abusive
05:50 PM roycroft: those 899+ pages are ignored
05:52 PM roycroft: i'm not sure qualcomm are evil
05:52 PM roycroft: it's the system in which they exist that is evil, if anything
05:52 PM roycroft: they're just doing what they need to do to survive within that system
05:54 PM lcnc-relay: <Lucid Nonsense@> They absolutely did not need to do this and I don't accept that at all, corps aren't living entities, every decision or consensus is made by human individuals,
05:56 PM roycroft: who are required by law to maximize the profit of their shareholders, to exclusion of anything else, subject only to legal constraints on their activities
05:56 PM roycroft: corporations have been sued by shareholders for doing things that benefit society but reduce profitibility
05:56 PM lcnc-relay: <Lucid Nonsense@> In fact, I think they saw the open source nature.and community of Arduino as a threat and deliberately did this to kill the movement
05:57 PM roycroft: and the courts have ruled in favor of the shareholders
05:57 PM lcnc-relay: <Lucid Nonsense@> So what
05:57 PM lcnc-relay: <Lucid Nonsense@> You do the right thing
05:57 PM roycroft: but you can't
05:57 PM roycroft: i just explained that
05:57 PM lcnc-relay: <Lucid Nonsense@> Of course you can
05:57 PM Tom_L: .
05:57 PM roycroft: if you do the right thing you get sued
05:57 PM lcnc-relay: <Lucid Nonsense@> And
05:57 PM roycroft: that's why i say it's the system, not the corporations
05:57 PM roycroft: and i think tom is done with this
05:58 PM roycroft: that's ok - i need to head to town now anyway
05:59 PM lcnc-relay: <alex.w#18266@> roycroft: I think it came out 5 years ago as esp32
06:00 PM lcnc-relay: <alex.w#18266@> roycroft: RPI also brings OS overhead and is often internet connected, which is a new can of worms to manage. Arduino/esp32 are great for simple controls that run a fixed codepath forever, sometimes in realtime
06:01 PM _unreal_: ve7it, I'm also working on trying to put together documents so its very easy to identify all the wires
06:02 PM xxcoder: well lets see if there will be clones.
06:02 PM xxcoder: likely will happen
06:02 PM lcnc-relay: <alex.w#18266@> That qualcomm/arduino agreement update does look terrible though. Some of it probably comes from a new set of lawyers (qualcomm), some of it might come from arduino IDE becoming the defacto user-friendly IDE for esp32 and other microcontrollers too?
06:02 PM lcnc-relay: <Lucid Nonsense@> There's been tons of clones for over a decade, Qualcomm is already starting to sue them
06:03 PM xxcoder: "we are out of good ideas" lawsuits it is then
06:03 PM xxcoder: just like apple
06:03 PM lcnc-relay: <Lesliet@> are there other ides one can use to program existing arduinos/clones?
06:03 PM lcnc-relay: <Lucid Nonsense@> It effectively kills the easy entry ecosystem until someone replaces it, which will take years
06:04 PM lcnc-relay: <Lucid Nonsense@> Lesliet@: Yes, but they're not beginner friendly
06:04 PM lcnc-relay: <Lesliet@> _nodnod_
06:04 PM lcnc-relay: <Lesliet@> lol, guess I'll be doing more with propeller chips again
06:05 PM lcnc-relay: <Lucid Nonsense@> There's microbit, but it's geared towards kids
06:06 PM lcnc-relay: <Lucid Nonsense@> Also though a BBC project, heavy Microsoft involvement
06:07 PM lcnc-relay: <Lesliet@> it has been nice having such a simple board, with all the hats that you can get, lots of ways to solve simple problems
06:07 PM lcnc-relay: <Lucid Nonsense@> Then again, think this will blow up, might get something going again quickly
06:07 PM lcnc-relay: <Lesliet@> yeah, I'm hoping it pisses off the right people. I'll happily jump to something new for that niche
06:08 PM lcnc-relay: <Lucid Nonsense@> Linus Torvalds might go nuclear
06:08 PM xxcoder: sadly im nowhere near being able to do something lol but hope some people will.
06:08 PM lcnc-relay: <Lesliet@> _big grin_
06:08 PM xxcoder: linus has hand in arudino?
06:08 PM lcnc-relay: <Lucid Nonsense@> No, but this sort of sabotage of open source will piss him off
06:09 PM lcnc-relay: <Lucid Nonsense@> He has an over the top temper
06:09 PM xxcoder: heard hes mostly better nowdays, if not 100%
06:10 PM lcnc-relay: <Lesliet@> the thoughts about much of this being a violation of GPL but getting sued into oblivion anyway as a small time player hit home as being likely. Be nice if someone with more power went to bat.
06:10 PM lcnc-relay: <Lesliet@> guess time will tell, tho
06:11 PM lcnc-relay: <Lesliet@> thinking about the XKCD story arc with Richard Stallman fighting ninjas
06:14 PM lcnc-relay: <Lucid Nonsense@> Yeah, we'll see, one saving grace might be that plenty of big companies use the open source arduino code in commercial products
07:02 PM _unreal_: Just got paid for the marble coasters I did today
07:43 PM _unreal_: ve7it, you live?
07:59 PM _unreal_: ve7it, one of the cool things is these panel pc's have 6 serial ports each, so I can tie all the PID ports directly IF I wanted
08:28 PM rdtsc: unreal, you offer a halftoning service yet? https://www.youtube.com/watch?v=wlumVxQ_t4o
08:46 PM _unreal_: rdtsc, I've never messed with that aside from laser
08:48 PM _unreal_: interesting but I'm not even advertizing currently and get a lot of biz
09:12 PM xxcoder: thathalftone is cool
09:14 PM fluffywolf: xxcoder: I don't remember, you ever watch Panga?
09:14 PM xxcoder: dont think so? dont seem familiar
09:15 PM fluffywolf: smm/smw hack player/creator... https://www.youtube.com/watch?v=B0eFWNUnzc0 his new kaizo hack.
09:16 PM xxcoder: definitely no. 5 hours wow
09:16 PM xxcoder: I only watch ryu and dgr, both usually during eating dinner
11:50 PM lcnc-relay: <Olli (RIO)@> moin moin
