12:00 AM ve7it: lack of Z motor made it hard to use
12:12 AM _unreal_: easy to build z
01:16 AM Deejay: moin
04:12 AM travis_farmer: Morning :-)
04:48 AM Nalesque: Hello
05:05 AM JT-Cave: morning
07:09 AM JT-Cave: rooster just crowed
07:09 AM JT-Cave: 43°F
07:10 AM travis_farmer: 48F with rain
07:14 AM Tom_L: 44

11:32 AM JT-Cave: hmm Woodcraft has 20% off on Robert Sorby turning tools
11:33 AM roycroft: they're pretty good tools
11:33 AM roycroft: well-made, ergonomic
11:33 AM roycroft: some folks don't like how soft they are
11:33 AM JT-Cave: I have a couple of them
11:34 AM roycroft: they require sharpening more often than some other makes
11:34 AM roycroft: i have sorby bench and mortise chisels, and a couple sorby turning tools, and i'm pretty happy with them
11:34 AM roycroft: i have to say, though, that my blue spruce paring chisels are amazing
11:34 AM JT-Cave: https://www.woodcraft.com/categories/turning-tools?brand%5B%5D=Sorby&featured%5B%5D=Sale&trk_msg=DQR6SCCK3R9KF0IB7JITLN67RK&trk_contact=BQP5A156FJPTT2I35NMP4F6DGS&trk_sid=0BOJB10RAPO5M2174A47N6B3L4&trk_link=P97IE14P5224PAMAF1FF622QVO&utm_source=listrak&utm_medium=email&utm_term=SHOP+NOW+-+SAVE+20%25+SORBY+TURNING+TOOLS&utm_campaign=Oct23&utm_content=Tab
11:35 AM roycroft: if i were rich i might replace mysorby bench chisels with blue spruce
11:35 AM roycroft: i like the feel of the sorby chisels a lot, though
11:35 AM roycroft: octagonal boxwood handles - very traditional
11:35 AM roycroft: and there's good reason for the tradition
11:36 AM roycroft: i bought a set of carbide turning tools earlier this year, but i haven't had a chance to use them yet
11:37 AM roycroft: i pulled out the lathe last week for the first time in months, and just had a simple job to do, so i grabbed the hss tools that were in the drawer
11:37 AM JT-Cave: I haven't turned much lately except a couple of lifting pucks for the C8
11:38 AM roycroft: turning isn't my thing
11:38 AM roycroft: i do it when i need to
11:38 AM JT-Cave: I enjoyed turning bowls
11:38 AM roycroft: i had a big, cheap lathe, from hf, and i sold it and got a mini lathe
11:39 AM roycroft: i got the extension bed for it, and it's a much better machine, but it is compact so i can store it easily
11:40 AM roycroft: https://www.teknatool.com/products/lathes/nova-comet-ii-midi-lathe/
11:40 AM roycroft: that's what i have now
11:40 AM roycroft: and i suspet it's all i'll ever need
11:41 AM roycroft: i don't do bowls, and the 12" swing is more than i'll ever need
11:41 AM roycroft: it can turn 42" between centers with the extension, which is also more than i'll ever need
12:01 PM CaptHindsight: roycroft: yah gonnah CNC dat lathe?
12:01 PM -!- #linuxcnc mode set to +v by ChanServ
12:02 PM CaptHindsight: JT-Shop: he rewrote it for you https://openlunchbox.com/mw19/index.php/HOWTO:_Gentoo_for_LinuxCNC
12:05 PM JT-Shop: looks better, I'll see if I have time to try it in the morning... in the middle of creating a new web site and trying to get the dns to point to the correct place
12:12 PM JT-Shop: but first a nap is in order
12:18 PM roycroft: no, capthindsight
01:00 PM solarwind: Hi all, can anyone identify the software he's using to demonstrate/animate that model? https://youtu.be/mfjp9i9aJDg?si=ENThpu9JCV_9Tm3C&t=128
01:01 PM solarwind: Like he's just clicking and dragging on an object while the rest of the model complies with that motion according to how the joints and rails are constrained
01:04 PM Tom_L: any decent cad would do that
01:05 PM solarwind: must be part of the "assemble" thing in Fusion360 I haven't touched
01:05 PM Tom_L: yup, assemblies
01:05 PM Tom_L: stress analysis etc etc
01:05 PM solarwind: I should look more into the "modelling" side of CAD, like Blender where I can import models into a simple game engine to do simulations
01:06 PM CaptHindsight: i get an autodesk vibe from the coloring
01:06 PM solarwind: CaptHindsight yeah that's what I was thinking too
01:06 PM CaptHindsight: SW, Catia, NX, Creo all do it, I guess F360 can as well, or look for AD Inventor
01:07 PM solarwind: Will definitely look at Inventor
01:07 PM solarwind: Been trying to find a way to do everything fusion360 can without the online/subscription nonsense
01:08 PM CaptHindsight: he comes across like a pro-sumer engi - neer ( close but not exactly)
01:08 PM CaptHindsight: so I bet F360
01:09 PM solarwind: Yeah Inventor can do everything I need, just took a look at it
01:10 PM solarwind: does stress analysis and assembly/animations too
01:11 PM CaptHindsight: Rhino can do the modeling and animation plus it has a 5-axis CAM plug-in
01:11 PM CaptHindsight: https://www.rhino3d.com/
01:11 PM solarwind: looking into it
01:12 PM solarwind: most important for me is availability (piratability)
01:52 PM bjorkintosh: solarwind, if you have a windows instance, solid edge is free for non-commercial use.
01:53 PM solarwind: bjorkintosh thanks, I'll take a look at that too
01:54 PM bjorkintosh: one of the few reasons I ever need windows is for CAD crap.
01:54 PM solarwind: yeah agreed
01:54 PM solarwind: CAD and video games lol
01:54 PM solarwind: good for nothing else
01:54 PM solarwind: WSL2 with Ubuntu makes it tolerable
01:55 PM bjorkintosh: x2x doesn't work properly on wsl2.
01:56 PM bjorkintosh: even paid for synergy and it broke randomly.
01:56 PM solarwind: ah yeah I haven't used it with any GUI/X programs, just command line stuff for development
01:56 PM solarwind: for that purpose, everything works
01:57 PM bjorkintosh: but for videogames, I think I'll get a steam deck when I have some spare change in 5 years!
01:57 PM solarwind: nothing beats a high end video card and 4k 120fps monitor or OLED TV
01:57 PM solarwind: no console can reach that visual fidelity
01:58 PM solarwind: an RTX4080 can run anything at max settings at 4k 120
01:59 PM solarwind: I have a PS5 and it'll run PS5 games way better than a PS5 can, it's insane
02:01 PM bjorkintosh: solarwind, come again?
02:01 PM bjorkintosh: you have a PS5 that runs PS5 better than PS5?
02:02 PM solarwind: I have a PS5, and my computer with an AMD Ryzen 7950X3D and nvidia RTX4080 can run the same games at higher frame rates and better visual quality than the PS5 can
02:02 PM solarwind: for example God of War, Spiderman, Horizon Zero Dawn which were all released for windows as well
02:03 PM bjorkintosh: oh I see.
02:03 PM solarwind: like more than 2x the frame rate
02:04 PM solarwind: The only reason I bought the console is for the exclusive games which are good. But then they released the exclusive games for windows, making the console superfluous
02:04 PM solarwind: so now I have a console that is good for nothing, begging to be sold
02:05 PM bjorkintosh: yeah but you get what you pay for, no? the ps5 costs $670 and the RTX4080 *alone* starts at $1100.00
02:05 PM solarwind: Yes, correct. For the price, the console will satisfy anyone
02:05 PM solarwind: But if you have $3,000, computer is unbeatable
02:06 PM solarwind: ps5 is only $500 CAD actually, the value is amazing
02:59 PM travis_farmer: maybe tomorrow i will take the shop A/C out, and put in the furnace for winter...
03:07 PM andypugh: Very off topic, but my great grandfather used to run this engine. https://www.youtube.com/watch?v=R331o_Ar56s 12,000 hp steam engine.
03:11 PM solarwind: andypugh there you are
03:12 PM solarwind: why can't I ever remember my questions about hardened steel when you're around
03:14 PM XXCoder: write it down
03:20 PM CaptHindsight: get a load ah Mr Fancy with his pencil and paper ^^
03:20 PM solarwind: Fountain pen collection and iroshizuku inks here
03:20 PM solarwind: favourite is the pilot vanishing point
03:21 PM solarwind: and Lamy 2000 but the plastic always forms a shiny smooth finish as the skin erodes away the matte texture. I HATE that
03:36 PM Tom_L: andypugh, is that near that other one you (i think it was you) have showed us?
03:36 PM travis_farmer: turns out my internet is either crap, from IRC: "No ping reply for 90 seconds, disconnecting.", or somebody is trying a low grade DDOS on my server... though 3 of the 4 people in the house are streaming videos...
03:38 PM andypugh: Tom_L: Hard to say, I can’t recall t’other one. Unless it was this one? https://www.youtube.com/watch?v=knclZgtILH4
03:38 PM andypugh: The two are about 50 miles apart
03:39 PM JT-Cave: hmm the first one was build 5 years before Tally Ho
03:40 PM travis_farmer: thanks again andypugh, for the help on the forum. :-) now i am at least hopeful for the future of it :-) (rather than wondering how much i could sell it for...)
03:41 PM travis_farmer: (my machine that is...)
03:41 PM Tom_L: andypugh, i think it was
03:42 PM andypugh: JT-Cave: The first steam-driven road vehicle was built in 1770. https://en.wikipedia.org/wiki/Nicolas-Joseph_Cugnot
03:42 PM andypugh: Yes, _17_70
03:43 PM XXCoder: yeah. I remember that weird tank in front lol
03:44 PM XXCoder: 1771 first car accient
03:44 PM XXCoder: supposely anyway. 1804 is first offical recorded one
03:45 PM CaptHindsight: is Cugnot pronounced Cugnot or Cugnot?
03:49 PM CaptHindsight: I have been accused of "Fardier à vapeur"
03:49 PM CaptHindsight: but it wasn't me
03:54 PM JT-Shop: https://www.facebook.com/marketplace/item/853541769408177/?ref=browse_tab&referral_code=marketplace_top_picks&referral_story_type=top_picks
03:58 PM andypugh: CaptHindsight: I always use koo-no and he hasn’t complained.
04:54 PM CaptHindsight: my last J-head BP was from 1960
04:56 PM CaptHindsight: I put it on CL an people didn't want ti because it was 3-phase. Then I relisted it with "easily converts to home use 208/240 with a VFD" and it sold the next day for the full asking price
04:57 PM CaptHindsight: I used it mostly as a precision drill press
05:00 PM solarwind: NOOOOOO don't let out our secret!!!
05:00 PM solarwind: I like being able to buy 3 phase motors for next to nothing
05:01 PM solarwind: I get rid of every single shitty single phase motor I can and get a 3 phase instead
05:01 PM solarwind: I got a 20kW motor for $100
05:02 PM CaptHindsight: I converted my old Clousing lathe to a 2hp 3ph motor
05:02 PM CaptHindsight: had the same issue, had to mention converts with a VFD and it also sold the next day
05:02 PM solarwind: You can buy a 2kW servo for less than the price of a new induction motor
05:03 PM solarwind: I'm strongly considering replacing the motor on my lathe with a leadshine 5kW AC servo
05:03 PM CaptHindsight: yeah, I got new pulls from an HVAC guy that got the wrong motors
05:03 PM solarwind: I'd still need an encoder on the spindle though
05:04 PM CaptHindsight: any, yes the world changes, and we laugh about how we used to drool over getting a 1GB hard drive someday for $2K
05:06 PM CaptHindsight: linear servos are also not costly to manufacture
05:06 PM CaptHindsight: the Chinese just need to start making some decent linear bearings
05:06 PM XXCoder: I hear 300 tb drive will be out pretty soon. I want it, not because I really need the size, but because its exactly million times larger than my first computer hd.
05:07 PM CaptHindsight: I think my first HD was a 20MB external
05:07 PM CaptHindsight: we didn't have to swap floppies anymore
05:07 PM CaptHindsight: before that it was tape drives
05:12 PM CaptHindsight: heh https://www.facebook.com/marketplace/item/841276487487840/?ref=product_details&referral_code=marketplace_top_picks&referral_story_type=top_picks
05:12 PM CaptHindsight: the pics look like a crime scene
05:13 PM solarwind: Yeah there's nothing complicated at all about linear motors. I think they're actually simpler than cylindrical
05:14 PM solarwind: The chinese definitely should start making them, even with not-so-good linear bearings
05:14 PM solarwind: because you can always mount them to good linear rails
05:15 PM solarwind: I want to get a linear servo just to play with
05:15 PM CaptHindsight: I have several in storage, next trip up I'll drag one along
05:15 PM solarwind: do you really?
05:16 PM CaptHindsight: yes
05:16 PM solarwind: I will buy one from you + shipping, let me know how much
05:16 PM CaptHindsight: 200-400mm travels
05:17 PM CaptHindsight: they are like at least 70-80lbs (25-35Kg)
05:17 PM CaptHindsight: Rockwell, so they were ~$8-10K new
05:18 PM CaptHindsight: I was going to make some CNC lathes
05:18 PM CaptHindsight: change out to air bearings
05:20 PM CaptHindsight: https://www.ebay.com/itm/195920107273
05:21 PM CaptHindsight: $349.99
05:22 PM CaptHindsight: https://www.ebay.com/itm/195916780220
05:23 PM CaptHindsight: still some deals
05:28 PM CaptHindsight: https://www.ebay.com/itm/313377478970 28 x 750mm Magnet US $750.00
05:53 PM JT-Shop: https://www.youtube.com/watch?v=WdK1qu3wqcA
05:59 PM Tom_L: is that considered fun?
05:59 PM JT-Shop: he seems to like it
06:00 PM Tom_L: i recall camping once with someone in a tent closeby and when morning came they'd rolled down the hill
06:00 PM JT-Shop: lol
06:03 PM * JT-Shop calls it a night
06:10 PM CaptHindsight: sometimes you just want to be alone and left in peace, and what better place than a cold and wet mountain top that is miles from the nearest town?
06:12 PM CaptHindsight: I was on a remote trail yesterday and after an hour I said "it's nice to be out here alone" just as a biker came around the corner
06:20 PM Unterhaus_ is now known as Unterhausen
06:21 PM Unterhausen: the coating on the magnets of one of our linear motors gave out. I spent a day cleaning up the mess
06:21 PM Unterhausen: so I could do some work. Fortunately, my boss got a donation of some new magnet strips
06:22 PM Unterhausen: I guess they eventually rust through after 20 years
07:09 PM andypugh: Anyone feeling brave? Completely untesed 2.9 ISO file. Just finished uploading. Too late to even try installing it: https://www.linuxcnc.org/iso/LinuxCNC_2.9.1-amd64.hybrid.iso
07:10 PM Tom_L: bookworm?
08:25 PM pcw--home: andypugh, did you test HAL_U32 and HAL_S32 modbus types, I'm not having much luck (sig 11s)
08:25 PM pcw--home: Unless i've done something stupid which is certainly possible: http://freeby.mesanet.com/gs10.mod
