12:18 AM lcnc-relay: <9ꌗ ❖ ravaged skies@> Guys what's that wood called that is similar to plywood but instead of layers of sheets, it looks like someone took a million larger chips of wood and compressed them flat into all directions
12:33 AM lcnc-relay: <9ꌗ ❖ ravaged skies@> I forgot the name but if I hear it, I'll recognize it immediately
12:33 AM lcnc-relay: <9ꌗ ❖ ravaged skies@> It's not particle board or MDF
12:33 AM lcnc-relay: <9ꌗ ❖ ravaged skies@> it's made with clearly visible larger chips of wood
10:58 AM roycroft: i use a venturi vacuum pump for my vacuum bag and clamping system
11:03 AM lcnc-relay: <skunkworks@> we do that at work. the table is a huge vaccum and the air sucks through the spoil board.
11:44 AM lcnc-relay: <Lucid Nonsense@> skunkworks@: What type of business is it?
11:45 AM lcnc-relay: <skunkworks@> Printing - mostly screen. Some digital and flexo
11:50 AM lcnc-relay: <Lucid Nonsense@> Ah, would have thought that was tricky to keep going these days
11:52 AM lcnc-relay: <Lucid Nonsense@> I'd like to have a go at Ben Kraznows screen printed acid etching at some point, though fibre lasers are getting cheap enough that it might be a bit redundant
11:55 AM _unreal_: just ordered one of these off ebay from a seller with good reviews BC-250 mining board
11:56 AM _unreal_: its the PS5 core hardware with some things disabled. runs linux and games amazing its like a $6k machine equal too
11:59 AM _unreal_: I'm planning to make it my living room MEDIA pc
11:59 AM _unreal_: also just finished cutting up a bunch of marble so i can finish cutting the coasters
12:27 PM Tom_L: latest touch gui for flex now available in inch and mm: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/Rpi5/
12:34 PM lcnc-relay: <skunkworks@> Screen printing is still a very robusts way to create decals for industrial applications.. (over lays and such). We certainly have innovated to stay in business. We were one of the first to go totally uv ink.
12:36 PM lcnc-relay: <Lucid Nonsense@> Cool, does it get a hardcoat on top, or robyst enough on its own?
12:36 PM _unreal_: sooooo I just discover I had a realllly bad laps of awareness. I was grinding my WET shoe. I even trimmed some of the fingers because they got under the rotary rasp for milling marble. I cant really get to the other side of the machine well and totally forgot that I have a niga rig setup to allow me to adjust the shoe height.
12:36 PM _unreal_: :(
12:37 PM _unreal_: soo annoying. I have CAD planned a second Z which is for the dust shoe but made a horrid mistake last year and tapped all of the holse to 3mm instead of 2mm
12:37 PM _unreal_: killing the ablity to mount the liner rail
12:37 PM lcnc-relay: <Lucid Nonsense@> Unfortunate typo there
12:38 PM roycroft: funny you should say that, skunkworks
12:38 PM roycroft: i've been pondering getting a uv printer for making things like that, but uv printers are so slow
12:38 PM _unreal_: roycroft, ditto
12:38 PM roycroft: i was wondering if screen printing with uv ink would be viable, as it would be so much faster
12:39 PM roycroft: sounds like it is
12:39 PM _unreal_: I just made $300 recently from a company building 3d printed camera mounts because they needed them to demo the cameras. the real mount where months behind
12:39 PM _unreal_: there is an all at once 3d print system I saw which is does full 3d prints in like 3 seconds
12:40 PM _unreal_: more or less rotates the fluid at a set speed and strobes the image in a special way and it just apears like magic almost instantly
12:42 PM _unreal_: lucid as soon as I get this next big check I'll be buying a fiber laser
12:42 PM _unreal_: I just have not decided on what to get yet.
12:42 PM * roycroft just ordered something from japan that he could not get domestically, and will get to see how tariff collection works soon
12:42 PM _unreal_: roycroft, I just paid $450 terrif
12:42 PM _unreal_: like??? 2 days ago
12:42 PM roycroft: this shouldn't be bad
12:42 PM roycroft: japan has a signed trade deal
12:43 PM roycroft: that allegedly means that there is no tariff yo-yo action for goods from japan
12:43 PM roycroft: and it's locked in at 15%
12:43 PM roycroft: it's a ~$200 item, so ~$40
12:43 PM roycroft: the seller says that "taxes and duties" are included
12:43 PM _unreal_: the stuff I ordered is comming from china
12:43 PM _unreal_: so :/
12:44 PM roycroft: i don't know if that means they broker the tariff cost or if i get to pay that
12:44 PM _unreal_: I've got 5 things comming from temu as well
12:44 PM _unreal_: if its included its already paid I would guess.
12:44 PM roycroft: but i assumed i would pay it when i placed the order, and am prepared for that
12:45 PM lcnc-relay: <Lucid Nonsense@> That's what happens when you elect Otto from a fish called wanda
12:45 PM _unreal_: the 2 computers I had to pay when they hit the USA main land
12:45 PM _unreal_: DHL
12:45 PM roycroft: i'm not going to go there today
12:45 PM _unreal_: cant wait to get them though
12:45 PM roycroft: thanks for the bait, though :)
12:45 PM lcnc-relay: <Lucid Nonsense@> Thought it was pretty good
12:46 PM _unreal_: those same industrial computers are about $6k each from local sellers
12:46 PM _unreal_: they also have like 6 com ports on them. not that Ineed them but still interesting
12:46 PM roycroft: china is still in tariff-of-the day status
12:46 PM roycroft: i can't order stuff with that kind of uncertainty
12:46 PM lcnc-relay: <Lucid Nonsense@> Don't call me stupid
12:47 PM _unreal_: still cant complain it was way cheaper then buying local... BY A LOT
12:47 PM lcnc-relay: <Lucid Nonsense@> Apologise!
12:47 PM roycroft: i'm fairly confident that the japanese tariff rate will not change within the next couple weeks
12:47 PM _unreal_: $1500 total
12:47 PM _unreal_: jap is what 10-20%?
12:47 PM roycroft: 15%
12:47 PM _unreal_: china is.... ouch
12:47 PM _unreal_: heh
12:48 PM roycroft: it's "ouch" on a good day
12:48 PM -!- #linuxcnc mode set to +v by ChanServ
12:48 PM roycroft: it's "yikes" on other days
12:48 PM roycroft: and sometimes "eek"
12:48 PM _unreal_: so I just finished cutting up a bunch of marble and am continuing to make the marble coasters
12:48 PM _unreal_: That will be a nice $500 pay day
12:48 PM lcnc-relay: <Lucid Nonsense@> Chinese navy deliberately made an incursion into Japanese waters overnight
12:49 PM _unreal_: I'll prob get some bubble wrap and have my daughter wrap them :)
12:49 PM * roycroft is heading out to finish the laser vent presently
12:49 PM roycroft: the rain is coming back at 1pm
12:49 PM roycroft: i'd like to be done with that before it rains
12:49 PM _unreal_: nothing like gettting your feet wet?
12:49 PM roycroft: i don't mind getting my feet wet, generally
12:50 PM xxcoder: raining here. I abused it by using it to clean my car. just wipe with rag. not super clean but my car was bit dirty
12:50 PM roycroft: i'm not interested in climbing a wet ladder
12:50 PM roycroft: and i need to glue the pipes and fittings together
12:50 PM xxcoder: yeah recipe for trip to hospital, tjat
12:50 PM roycroft: pvc glue works best when the parts are not wet
12:51 PM * roycroft has had enough of hospitals in the last couple years, and is not interested in a visit to one again
12:51 PM roycroft: i have to go to town today as well
12:51 PM roycroft: i'll wait for the rain to do that - i don't mind driving in the rain, as my car has a roof
12:51 PM xxcoder: indeed. hospital may be friendly place with good professionals, but still not place we want to visit in general lol
12:51 PM _unreal_: town... ya going to the fresh market later today
12:51 PM lcnc-relay: <CaptainHindsight@> I keep asking Chinese machine shops which brands of Chinese CNC machines are now on par with western made CNC machines. They never answer the question.
12:51 PM _unreal_: get some coffee beans
12:52 PM roycroft: captainhindsight: i think they keep all the good ones for themselves
12:52 PM roycroft: i just bought coffee a couple days ago - i'm good for another couple weeks
12:52 PM xxcoder: capt yeah when its chinese, not "relabeled" by american companies with good qa, I assunme is going to be worse than american products in general
12:52 PM _unreal_: I use a spong co. antique coffee grinder
12:52 PM lcnc-relay: <CaptainHindsight@> They have shops there now that know what they are doing. They make aerospace parts in volume now.
12:53 PM roycroft: i make espresso drinks
12:53 PM roycroft: i need a good coffee grinder for that, and have one
12:53 PM lcnc-relay: <Lucid Nonsense@> Are they using Chibese macgibes though
12:53 PM lcnc-relay: <Lucid Nonsense@> Wtf
12:53 PM lcnc-relay: <Lucid Nonsense@> Chinese machines
12:53 PM roycroft: an antique coffee grinder is not going to do espresso grind
12:53 PM _unreal_: thats the kind I have https://www.ebay.com/itm/406234250312?chn=ps&mkevt=1&mkcid=28&google_free_listing_action=view_item
12:53 PM lcnc-relay: <CaptainHindsight@> chinese work ethics are another story
12:53 PM roycroft: as i've said many times before, the chinese can make high quality machines
12:54 PM roycroft: we see junk machines here from china because they won't make high quality machines cheaply
12:54 PM _unreal_: no its for french press
12:54 PM lcnc-relay: <Lucid Nonsense@> They should be capable, but I've heard China is helping Russia import Fanuch hardware clandestinely rather than just selling them their own
12:54 PM roycroft: they pay more attention to how much you're willing to pay than the quality you request
12:54 PM lcnc-relay: <Lucid Nonsense@> Fanuc
12:55 PM roycroft: and they make things whose quality matches what you're willing to pay for them
12:55 PM lcnc-relay: <CaptainHindsight@> <--- not a fan of Fanuc
12:55 PM lcnc-relay: <Lucid Nonsense@> Taiwan though, seem very much up to par
12:55 PM _unreal_: I'm waiting for this https://www.temu.com/goods.html?_bg_fs=1&goods_id=601101702445607&sku_id=17601097321238&_x_sessn_id=yz1q44outs&refer_page_name=bgt_order_detail&refer_page_id=10045_1763319297015_9ik9x9jzjv&refer_page_sn=10045&adt_btn_confirm=0&mn_ext=
12:55 PM lcnc-relay: <CaptainHindsight@> old and clumsy UI's
12:55 PM xxcoder: is that rpi ripoff?
12:56 PM roycroft: taiwan have upped their game since the crap they made in the '60s
12:56 PM lcnc-relay: <Lucid Nonsense@> Yeah and expensive software ootions on robots
12:56 PM lcnc-relay: <Lucid Nonsense@> Options
12:56 PM roycroft: but the difference is that the taiwanese say "this is what we make and this is what it costs", while the chinese say "how much do you want to pay? we'll make things that are worth what you're willing to pay"
12:56 PM _unreal_: rpi rip off sure... regardless its going to run a future plasma cutter
12:57 PM lcnc-relay: <Lucid Nonsense@> There is something about Japanese culture which favours obtuse UIs
12:57 PM lcnc-relay: <CaptainHindsight@> Fanuc just keeps their GUI's the same so that you have to pay for their training
12:57 PM roycroft: and if you're wal*mart you say "we'll pay you $1.99 to make something whose domestic equivalent sells for $40"
12:57 PM roycroft: and the chinese happily give them a product that resembles the $40 one but is worth $1.99
12:59 PM lcnc-relay: <Lucid Nonsense@> Dunno, Chinese quality is getting a lot better in many areas
12:59 PM xxcoder: yeah. if you pay properly
12:59 PM xxcoder: and have qa
12:59 PM xxcoder: thats roys point. china can make very good stuff. its just american companies thats too cheap
12:59 PM lcnc-relay: <Lucid Nonsense@> West handed them all the info and experience they needed
12:59 PM roycroft: in other words, the chinese are inspired by the ferengi
12:59 PM xxcoder: along with cultural difference
01:00 PM xxcoder: sure on info and experence. its going to happen anyway
01:00 PM roycroft: the chinese handed a lot of info and experience to the west about 2000 years ago
01:00 PM roycroft: it's not a one-way thing
01:01 PM xxcoder: yep. more info flow, more science breakthoughs
01:01 PM xxcoder: always how it worked
01:05 PM roycroft: ok, time to go finish the vent, so i can work with the laser when i get back from town
01:05 PM roycroft: the honeycomb standoffs are done and installed, so the vent is all that is left for it to be fully functional
01:09 PM lcnc-relay: <Lucid Nonsense@> I've been looking at compressors lately because I'm under capacity. Big compressors are big money even used though, wondering if two cheap ones in parallel jnto a big receiver would work just as well
01:09 PM lcnc-relay: <Lucid Nonsense@> Obviously, would need some electronics tinkering to trigger at the same time
01:29 PM lcnc-relay: <skunkworks@> Lucid Nonsense@ it might get a clear coat depending on the application.. we do a lot of sub-surface printing.
01:29 PM lcnc-relay: <skunkworks@> Na - just one pressure sensor running both contactors..
01:29 PM lcnc-relay: <Lucid Nonsense@> skunkworks@: Cool, not a subject I know much about
01:30 PM lcnc-relay: <Lucid Nonsense@> skunkworks@: Thanks, I think I will try that
01:32 PM lcnc-relay: <Lucid Nonsense@> First, I need to build a shed to house them, and the dust collector, they still make me jump 1 out of 5 times and I hate it
01:32 PM lcnc-relay: <skunkworks@> lol
01:32 PM lcnc-relay: <skunkworks@> the problem around here - is the place the aircompresor is stored really should be heated
01:33 PM _unreal_: good lord the final cut out really screams
01:33 PM _unreal_: loud
01:33 PM lcnc-relay: <Lucid Nonsense@> For condensation you mean?
01:33 PM lcnc-relay: <skunkworks@> yes
01:34 PM lcnc-relay: <Lucid Nonsense@> I've heard of people doing the opposite
01:34 PM lcnc-relay: <Lucid Nonsense@> Because the iar gets heated by the compressikn
01:34 PM lcnc-relay: <Lucid Nonsense@> Air
01:36 PM _unreal_: when I get to it I'm planning on putting my air compressors in the attic
01:36 PM _unreal_: I've got 2 old pig style air compressors, sears craftmans
01:37 PM lcnc-relay: <skunkworks@> lol - We still have on of those. It might have been wards though..
01:37 PM lcnc-relay: <Lucid Nonsense@> So an aftercooler sorta job
01:37 PM _unreal_: got two of these https://i.ebayimg.com/00/s/MTIwMFgxNjAw/z/BnMAAeSwMexovbZ8/$_57.JPG?set_id=880000500F
01:38 PM lcnc-relay: <skunkworks@> one lunger?
01:38 PM _unreal_: 2
01:38 PM _unreal_: both are dual piston
01:38 PM lcnc-relay: <skunkworks@> ah - ours is single
01:38 PM lcnc-relay: <skunkworks@> think 80psi is the max.
01:45 PM lcnc-relay: <ccatlett1984@> @_unreal_ you don't want the BTT pi v1.2, it's similar performance to a Pi 3b
01:52 PM lcnc-relay: <skunkworks@> https://jauriarts.org/_heisenbridge/media/jauriarts.org/wcjteRPGopYsPbOZOMvgYOCZ/GJKT9LGmMOk/PXL_20251116_194844096.jpg
01:53 PM lcnc-relay: <skunkworks@> Think we have had it since before I was born
01:53 PM lcnc-relay: <skunkworks@> Dad obviously made the filter housing
01:54 PM rdtsc: highly effective though :)
01:56 PM -!- #linuxcnc mode set to +v by ChanServ
01:58 PM Tom_L: skunkworks, nice air cleaner :)
01:59 PM _unreal_: ccatlett I absolutly want it and being similar to pi-3 is more then fine
01:59 PM _unreal_: when I build it my plasma cutter will be a GRBL controlled setup
02:02 PM _unreal_: skunk the 3rd one I have is just like the craftman BUT its a bit larger its 220v only and its got the same kind of STEEL head only dual cylinder
02:03 PM _unreal_: skunk, correct me if I'm wrong but that picture you posted if you have that I'm assuming it gets REAL hot if run for too long
02:03 PM _unreal_: hate to see that thing get a blow down though :S
02:04 PM lcnc-relay: <Lucid Nonsense@> skunkworks@: It looks unhappy about your visit and has a shotgun in the back
02:06 PM lcnc-relay: <Lucid Nonsense@> Really liking ASA filament lately, prints well, doesn't melt or snap by breathing on it
02:06 PM lcnc-relay: <Lucid Nonsense@> https://jauriarts.org/_heisenbridge/media/jauriarts.org/UkQoxUcrhyBEvKhnJFUCVkSc/68Lbe5kMksc/20251116_195713.jpg
02:08 PM lcnc-relay: <Lucid Nonsense@> Dust attachment for Makita plunge base
02:14 PM lcnc-relay: <Lesliet@> got a gasket designed, and found that no, Fusion 360 won't export a drawing as an svg. Export as pdf>>open in Inkscape>>export as SVG
02:15 PM lcnc-relay: <Lesliet@> should probably learn to draw in Inkscape, but too much software to learn right now
02:15 PM lcnc-relay: <Lesliet@> anyway, time for a store run in town, and then I can screw around and see if I can cut it out of notebook paper to check fit
02:16 PM lcnc-relay: <Lucid Nonsense@> Odd, haven't tried, but should do dxf I would have thought
02:16 PM lcnc-relay: <Lesliet@> yes, it will export DXF
02:16 PM lcnc-relay: <Lesliet@> interested to see if FreeCad will export SVG files
02:17 PM lcnc-relay: <Lucid Nonsense@> Autodesk doesn't like anything open source at a guess
02:17 PM lcnc-relay: <Lesliet@> yeah, it is mildly irritating, as well, that every time I want to use fusion, I have to go through all this security log in stuff. Nobody uses this computer but me, so not terribly worried
02:18 PM _unreal_: spaceclaim and fusion360 have no issues
02:19 PM lcnc-relay: <Lesliet@> ?
02:41 PM _unreal_: importing and exporting those formats
02:42 PM _unreal_: I own a number of cad programs use them all as well depending on what I'm doing
02:42 PM _unreal_: though I use ESTLcam when it comes to cam jobs
02:42 PM _unreal_: simply the best IMO
02:43 PM _unreal_: god thats so loud
02:56 PM roycroft: yay - the vent is fully installed and working
02:56 PM roycroft: and the rain will begin any minute
02:58 PM roycroft: i think i'll go to town now instead of later, so i won't be driving in the heavy rain so much
02:58 PM roycroft: and i'll be sure to get home by dark
03:00 PM roycroft: i've found multiple kerf compensation test files for lightburn online, so when i get back i'll get to that task without having to do any math or measuring
03:00 PM roycroft: one is really neat - it acts like a vernier caliper
03:03 PM lcnc-relay: <Lucid Nonsense@> Not my model btw, wouldn't have tried to invent every possible stress riser, but seem to be getting away with it
03:18 PM lcnc-relay: <Lucid Nonsense@> If I don't stop watching Andreew Camerata videos. I'll end up with a 14 ton digger I don't need
03:18 PM JT-Shop: yay the trailing arm is primed... last part to paint
03:20 PM lcnc-relay: <Lesliet@> _unreal_: in Fusion 360, I know how to import SVG's, but could not find a way to export SVG's from a model or drawing. Googling it, it appeared one person found some sort of plug in, but I couldn't find that, seemed like they had a different version
03:21 PM lcnc-relay: <Lesliet@> So if you know how to do that, I'd appreciate learning that info
03:47 PM rigid_ is now known as rigid
04:04 PM Unterhaus_ is now known as Unterhausen
04:48 PM lcnc-relay: <Lesliet@> ok, Freecad has an amazing number of different export formats you can use for a drawing. Liking this.
04:48 PM lcnc-relay: <Lesliet@> fusion shows 4. Freecad has an entire page
04:49 PM xxcoder: yah thats big thing about open source
04:49 PM xxcoder: person wants some X format import or export? its likely will be added, by that person directly, or by asking some good programmer
04:52 PM lcnc-relay: <Lesliet@> so far, it seems pretty intuitive. I like that they have a menu to choose for it to act like other software you may be used to, like "cad" or "blender"
04:53 PM lcnc-relay: <skunkworks@> I have drawn profiles up in acad (because I am way better at it) and exported as dxf - then imported them into freecad to make a solid..
04:54 PM lcnc-relay: <Lesliet@> kinda wish it showed me clearly what's not constrained, but that's probably going to just be a procedural thing like so much in fusion is. eg, do things in the right order, and constrain properly as you go
04:55 PM lcnc-relay: <Lesliet@> worked through the first "first steps " tutorial
04:56 PM lcnc-relay: <Lesliet@> had to laugh at myself, trying to figure out how to install it, and then discovering I already had it installed on this linux box
04:56 PM lcnc-relay: <Lesliet@> no need to start the engine, when it is already running >.<
05:04 PM _unreal_: let the milling continue
05:05 PM _unreal_: making 2 more coasters as extra that I'm not charging for. they are mable so I dont entirly trust that they are internal fracture fre
05:05 PM _unreal_: free
05:47 PM lcnc-relay: <CaptainHindsight@> https://photos.app.goo.gl/JGKrUPsv7Ud9iSbW6
05:47 PM lcnc-relay: <CaptainHindsight@> https://photos.app.goo.gl/GLKSLrnSqSBauTPz8
05:51 PM lcnc-relay: <CaptainHindsight@> CNC Batcave ^^ 🙂
05:52 PM xxcoder: whatever camera you used was very low react time, so everythings blurry in motion lol
05:52 PM lcnc-relay: <CaptainHindsight@> not China, China would be bewer and cleaner
05:52 PM lcnc-relay: <CaptainHindsight@> bewer/newer
05:54 PM lcnc-relay: <CaptainHindsight@> xxcoder: it was dark there at 3am, motion activated lights
05:54 PM xxcoder: ahh ok
05:54 PM lcnc-relay: <CaptainHindsight@> horrible job
05:55 PM xxcoder: security?
05:55 PM lcnc-relay: <CaptainHindsight@> CNC repair and PM's
05:55 PM xxcoder: ahh ok
05:55 PM lcnc-relay: <CaptainHindsight@> mostly Toyodas with FANUC controls
05:56 PM lcnc-relay: <CaptainHindsight@> https://jauriarts.org/_heisenbridge/media/jauriarts.org/wbuWHDVslPhdcepTWIgfZCRT/DQHp7pMQJ8g/8bbaf056-f114-4aa7-8e23-1b43e6f298991.jpg
05:57 PM xxcoder: looks like lot of maintance
05:58 PM lcnc-relay: <CaptainHindsight@> 100 L oil changes
06:00 PM lcnc-relay: <CaptainHindsight@> ^^ this one had the Y axis re-machined and some idiot dropped it while moving it with a forklift
06:01 PM lcnc-relay: <CaptainHindsight@> https://jauriarts.org/_heisenbridge/media/jauriarts.org/jchniqqTdPPzVwtDkpglANxE/NhQHmLd9dXE/f4786e6a-e158-4dba-8f09-1b5e38fb7bd01.jpg

06:03 PM lcnc-relay: <CaptainHindsight@> everything was just filthy and full of chips
06:04 PM xxcoder: wow
06:04 PM xxcoder: reminds me of that time company i worked for sold one of older machine
06:05 PM xxcoder: they tried to move it, it was way too heavy and it was empty of chips and coolant
06:05 PM xxcoder: turns out space under, along with servos, etc, was completely crammed full of chips
06:06 PM xxcoder: it was insane seeing barely exposed servo motor with tight metal chips packed around it
06:06 PM lcnc-relay: <CaptainHindsight@> yeah, we'd spend hours with air chisels
06:07 PM lcnc-relay: <CaptainHindsight@> so much fun
06:07 PM xxcoder: lol
06:07 PM lcnc-relay: <skunkworks@> 42 almost has another 2 ton in it
06:08 PM lcnc-relay: <skunkworks@> Found a transmission jack
06:08 PM lcnc-relay: <CaptainHindsight@> https://jauriarts.org/_heisenbridge/media/jauriarts.org/exdnmAcCevlfQaTDvoXkIcSs/ZrDyWVOonuc/50843992-a9c5-4ae0-b8a0-dbf86f3442ff1.jpg
06:08 PM lcnc-relay: <CaptainHindsight@> just about everything leaked
06:10 PM lcnc-relay: <CaptainHindsight@> the operators would also sabotage machines
06:13 PM lcnc-relay: <CaptainHindsight@> https://jauriarts.org/_heisenbridge/media/jauriarts.org/nOuXwTykvTDsqiTfpquqwcZF/9Syk9iCZ5FI/c855f546-2e89-4322-bac4-f6556b24338e1.jpg
06:13 PM lcnc-relay: <CaptainHindsight@> damaged way covers were a near daily thing at times
06:14 PM xxcoder: I guess stobage = paid holidays
06:15 PM lcnc-relay: <CaptainHindsight@> we had operators ask us if we found anything inside the machine
06:16 PM lcnc-relay: <CaptainHindsight@> "oh like a two foot long wrench?" "nope we didn't see it"
06:17 PM lcnc-relay: <CaptainHindsight@> they would want it back
06:17 PM Tom_L: looks like one of those run em until they quit places
06:18 PM lcnc-relay: <CaptainHindsight@> exactly that
06:18 PM Tom_L: can you fix it by tomorrow?
06:18 PM lcnc-relay: <CaptainHindsight@> they were ordered by HQ to shutdown all machines by Jan 1
06:19 PM lcnc-relay: <CaptainHindsight@> all to be auctioned off
06:19 PM _unreal_: ok milling the final coaster now
06:19 PM lcnc-relay: <CaptainHindsight@> tomorrow?!, hah, by the end of your shift
06:19 PM Tom_L: closing shop?
06:20 PM _unreal_: I've bubble wrapped all the others in fact I'm making 2 xtra outside of the order because I'm fearful one could break, internal fractures
06:20 PM lcnc-relay: <CaptainHindsight@> all machining was to be farmed out and the plant would now be 100% assembly
06:21 PM _unreal_: btw when I get paid for these I'll be ordering the 7i96
06:21 PM Tom_L: _unreal_, where do you source your stone? counter top shops?
06:21 PM _unreal_: believe it or not WORK
06:21 PM Tom_L: sure you don't want the "S"
06:21 PM Tom_L: ?
06:22 PM _unreal_: I work in the luxury yacht industry, you would be amazed how often they are changing up there marble
06:22 PM Tom_L: i know
06:22 PM _unreal_: they just bash it and trhow it out
06:22 PM _unreal_: I grab the big useful chunks from the bins
06:22 PM Tom_L: i saw a few when i was in Miami
06:23 PM _unreal_: wholy crap its 50f outside
06:23 PM _unreal_: was 80 today
06:23 PM Tom_L: 62F here
06:23 PM xxcoder: might actually snow there
06:23 PM roycroft: it started raining just as i was pulling out of my driveway on my way to town
06:23 PM xxcoder: 54f here
06:23 PM lcnc-relay: <CaptainHindsight@> companies like ATS charge ~ $150/hour for repair and PM's, the techs make ~$50/hour
06:23 PM _unreal_: I had a squirrel moment, noticed the weather deamon
06:24 PM roycroft: it's raining like crazy in the valley still, but it has stopped here
06:24 PM Tom_L: nice sunny day
06:24 PM _unreal_: Tom_L, s or non s version I'm not sure
06:24 PM _unreal_: one is going to drive a lathe and the other is going to drive a metal mill
06:25 PM _unreal_: both machines are side by side, I'm hoping to get you guys aid, honistly I'm hoping to generate a standard setup for them that can then be pushed to the public
06:25 PM * roycroft is picking out a kerf compensation file now, and will be running it shortly
06:25 PM Tom_L: nothing is 'standard' about these cncs
06:26 PM _unreal_: no but usable fuctions are
06:28 PM _unreal_: speaking of. which would you use on a lathe vs end mill, 7i96/7i96s
06:28 PM _unreal_: I believe you have see pictures of my endmill and lathe ya?
06:28 PM Tom_L: oh probably
06:28 PM roycroft: a 7i96s would be fine for both a lathe and a mill
06:29 PM Tom_L: it depend if you want to drive a spindle with an analog signal or not
06:29 PM _unreal_: roycroft, I dont recall the exact difference between them
06:29 PM Tom_L: the S is spindle control
06:29 PM _unreal_: which spindle, lathe or mill
06:29 PM Tom_L: i don't think it matter ehh??
06:30 PM Tom_L: the electronics don't care
06:30 PM _unreal_: let me re-phrase the question,
06:31 PM _unreal_: what could use more work as a comunity driven feature, s on a mill or s on a lathe? I'm not beyond upgrading ether with extra features. though both are "small machine shop tools"
06:31 PM roycroft: the 7i96s can control an analog spindle, and the 7i96 cannot
06:32 PM roycroft: i believe the 7i96s has fewer io pins because of the analog spindle pins
06:32 PM _unreal_: yes thankyou for restating that..
06:32 PM roycroft: but i don't recall exactly
06:32 PM Tom_L: then there is spinx
06:32 PM Tom_L: single channel analog control
06:32 PM _unreal_: right now both machines are modified by the original owner but OLDSCHOOL machines
06:32 PM roycroft: other than the spindle support the two boards can do the same thing
06:32 PM Tom_L: either board can be expanded
06:32 PM roycroft: so it depends on the spindle on each machine
06:33 PM _unreal_: the lathe is larger then the normal version of its self. and I forget what he did to the endmill
06:33 PM Tom_L: via header and sserial
06:33 PM roycroft: to state it slightly differently
06:33 PM roycroft: anything the 7i96 can do the 7i96s can also do
06:34 PM _unreal_: roycroft, you missed your moment, should have sung it, """"" anything the 7i96 can do, the 7i96s can do betterrrrr.....""
06:34 PM roycroft: but it can't
06:34 PM roycroft: it can do it the same
06:34 PM roycroft: but it has an extra feature
06:35 PM * roycroft continues checking out kerf compensation files
06:35 PM Tom_L: hah, i still have sserial wired up on my test 7i96s
06:35 PM _unreal_: btw I made up my mind, I'm going to stepper the lathe, and brushed servo the endmill
06:35 PM _unreal_: and when I build it I'm going to BLDC the plasma
06:36 PM _unreal_: I swear people in my industry are conspiring to make me rich
06:36 PM Tom_L: don't spend it all at once or in one place
06:36 PM _unreal_: My biggest request is stainless etching
06:37 PM Tom_L: roycroft, do laser cuts fan out at the bottom like say a waterjet
06:37 PM _unreal_: which I cant do till I get the fiber laser :/
06:38 PM _unreal_: Tom_L, I'm not sure I understand your question to roy
06:38 PM _unreal_: roycroft, ?
06:38 PM roycroft: depending on how thick the material and how powerful the laser and where you focus the laser, they do vary in width
06:38 PM roycroft: usually it's more an hourglass shaped cut
06:38 PM _unreal_: Z is important
06:38 PM roycroft: i.e. the laser focuses in the middle of the material, and the cut is narrowest there
06:39 PM roycroft: it fans out at the top and bottom
06:39 PM _unreal_: very true, hence its best to have a long narrow focus with Z compensation.
06:39 PM roycroft: but for relatively thin material the fanout is negligable
06:40 PM _unreal_: roycroft, its always amazed me how laser energy has MAS with out weight
06:40 PM roycroft: my laser is entry level, and does not have automated z adjustment
06:40 PM roycroft: i have to manually focus
06:40 PM _unreal_: roycroft, I would strongly suggest adding z
06:40 PM roycroft: if i had a z axis motor i could make a cut in multiple passes and refocus on each pass
06:41 PM roycroft: that would mostly mitigate the fanning
06:41 PM _unreal_: IT MADE A world of a difference on my machine same with adding the air assist
06:41 PM roycroft: i have air assist already
06:41 PM _unreal_: thumbs up
06:41 PM roycroft: i don't need z on this machine
06:41 PM roycroft: my next laser, perhaps
06:41 PM roycroft: but it's not worth upgrading this machine with a z axis
06:41 PM _unreal_: I've done depth etchings with my laser even at a 3watt UV
06:41 PM _unreal_: came out amazing
06:42 PM Tom_L: does a laser require a 'leadin' 'leadout' move for the cut?
06:42 PM _unreal_: no
06:42 PM Tom_L: to allow for where it starts to burn thru
06:42 PM roycroft: my 5w head just uses the kickstand to focus
06:42 PM _unreal_: Tom_L, that is more for things like a water jet
06:42 PM roycroft: but my 20w head has the kickstand for focusing at the top of the part, and it has an adjustment for cutting deeper
06:43 PM Tom_L: plasma as well
06:43 PM _unreal_: Tom_L, i'm sure there are times where a lead in is useful but it has more to do with the chances of having over cutting or blowouts at the onset
06:44 PM _unreal_: so ya waterjet and plasma for sure like lead-in's laser your more likely to want a lead-in if your running a laser CUTTER.
06:44 PM _unreal_: laser cutters, HIGH END one's are setup more like a plasma and have a high volume air assist to work just like a plasma
06:44 PM _unreal_: and very much so want a lead in
06:46 PM roycroft: i will be mostly doing engraving with my laser
06:46 PM roycroft: but for the jig system i'll be cutting the parts out
06:47 PM _unreal_: roycroft, when I get to doing the BIG upgrade I've got a :( was supposed to be 40 watt but turns out to be a 30 watter laser head, still 30 watt laser for the current machine I'm sure you have seen the photos of
06:47 PM roycroft: yeah, you shared pics of that
06:47 PM lcnc-relay: <CaptainHindsight@> Tom_L: which controls were on the machines at your old shop?
06:48 PM roycroft: i was thinking about getting the 40w laser head for my machine, but decided that when i need that much power i'll get a bigger machine that is built with a proper enclosure
06:48 PM Tom_L: i'm not sure on the control but he had a couple tree vmc and some okumas
06:48 PM xxcoder: could your current one cut plywood?
06:48 PM roycroft: i have a 5w and 20w diode head for mine, as well as a 3w ir head
06:49 PM Tom_L: my kid mostly runs siemen
06:49 PM Tom_L: but knows fanuc
06:49 PM roycroft: i'm cutting 5mm plywood with it to make the jigs
06:49 PM lcnc-relay: <CaptainHindsight@> https://jauriarts.org/_heisenbridge/media/jauriarts.org/nAdSAzsaFmQPphscyqFuSSdx/vj4SGZ2lvMs/443d30bb-427c-4a98-bccd-1adf5a3d4aba1.jpg
06:49 PM xxcoder: nice. well if you plan to sell it to replace with bigger, I might want to buy it
06:49 PM _unreal_: xxcoder, me or roycroft
06:49 PM xxcoder: roy
06:49 PM _unreal_: and 3watt 5 watt NOT they can not
06:49 PM roycroft: i can do it in 3 slow passes
06:50 PM roycroft: but i get a lot of charring, so i'm taking 7 fast passes to get the cleanest cuts
06:50 PM _unreal_: what 4mill
06:50 PM Tom_L: capn, those were siemen: http://tom-itx.no-ip.biz:443/~webpage/cnc/cincinnati/Cincinnati_3.jpg
06:50 PM roycroft: i could cut thicker plywood but it would take more passes
06:50 PM roycroft: i'm cutting 5mm plywood currently
06:50 PM Tom_L: old ones
06:50 PM _unreal_: Tom_L, so ya can is CUT yes, clean and useable ehhhhhhhhh
06:51 PM _unreal_: hence I said no
06:51 PM roycroft: the ir laser head will not cut most wood at all
06:51 PM roycroft: the only wood i've been able to cut with it even somewhat is white pine
06:51 PM _unreal_: IR is a different wave
06:51 PM xxcoder: if roy says it can, it can. roy isnt given to lying.
06:51 PM roycroft: and even then, it only cuts the pitch pockets
06:51 PM _unreal_: UV does the best at cutting organics
06:52 PM roycroft: xxcoder: i'm using a 20w head to cut the 5mm plywood
06:52 PM _unreal_: fiber does a good job with things like metal, CO2 I believe does acrylics really well
06:52 PM xxcoder: makes sense
06:52 PM roycroft: i could cut it with the 5w head, but it would take like 30 passes (and forever)
06:52 PM xxcoder: yeah I would use 30w too lol
06:53 PM _unreal_: roycroft, you never said that I know of having a 20 watt only talked about the 5 watt
06:53 PM _unreal_: so ya as I said a 5watt is a NO
06:53 PM xxcoder: err 20w I meant
06:53 PM roycroft: but i was discussing my 20w head when xxcoder asked the question
06:53 PM roycroft: you probably did not notice
06:53 PM _unreal_: likely
06:53 PM roycroft: but i disagree with you
06:53 PM roycroft: 5w is not a NO
06:54 PM roycroft: 5w is more a "yes, but nobody would ever want to"
06:59 PM xxcoder: plywood and cardboard is what I wanted to work on lol. mostly latter
06:59 PM _unreal_: xxcoder, you want power, LOW power makes fires
06:59 PM _unreal_: because it takes so long
07:00 PM xxcoder: oh boy. stir fry veggies, cooked bit differently was quite tasty. I just used airfryer, 25 min at 400f but shaken each 10 minutes. pan was coated with oilve oil, and veggies had thin spray on it. I added garlic japeleno salt, and some MSG
07:00 PM roycroft: you have to take a buttload of fast passes
07:00 PM xxcoder: yeah, I know unreal :)
07:01 PM xxcoder: my last laser machine failed due to that
07:01 PM * roycroft is tired of explaining this and focuses on finding the vernier kerf compensation cut file that he was looking at earlier
07:54 PM xxcoder: oh got refund from ebay on the fraud package
07:54 PM xxcoder: and I have another one coming
07:55 PM xxcoder: I asked for refund, not reship, it was seller decision to ship another to me
07:58 PM xxcoder: honestly wouldnt be surpised if it was another fraud, or even just packag with trash in ut
08:33 PM roycroft: wow
08:33 PM roycroft: if this file works right, i have a huge kerf - 0.2125mm
08:33 PM xxcoder: could it be focused more? or is it "low point" in focus curve?
08:34 PM roycroft: i focused at the top of the part
08:34 PM roycroft: i should focus in the middle and try it again
08:34 PM xxcoder: maybe good idea to test that
08:34 PM roycroft: but that means i have to figure out how to do the focus adjustment
08:34 PM roycroft: i think it's pretty easy
08:44 PM roycroft: it's a weird setting
08:45 PM roycroft: but it was set at 18mm material already
08:45 PM roycroft: i just set it to 5mm
08:45 PM xxcoder: so it focuses itself based on height of material?
08:45 PM roycroft: that should go a lot better
08:45 PM roycroft: no, it's manually focused
08:45 PM xxcoder: oh
08:45 PM roycroft: there's a kickstand on the side of the laser module
08:46 PM roycroft: you drop it down, lock it in place, then lower the laser head until the kickstand touches off on the material
08:46 PM roycroft: then lock the head, unlock the kickstand, and raise the kickstand back up
08:46 PM _unreal_: ve7it, I've gotten the drivers mounted into the new case this weeknd
08:47 PM roycroft: there is an independent adjustment that adjusts the length of the kickstand below the lens
08:47 PM roycroft: that is what is used to focus on thicker materials
08:51 PM roycroft: yeah, it's engraving and cutting a lot cleaner now
08:51 PM xxcoder: so you adjust that eh. and thats good
08:54 PM roycroft: 0.100mm kerf now
08:55 PM roycroft: vast improvement
08:57 PM xxcoder: indeed
08:57 PM roycroft: the 20w module is the only one that has the thickness adjustment
08:57 PM roycroft: i had never used it
09:03 PM xxcoder: you know how now :)
09:03 PM xxcoder: .1mm is certainly small
09:04 PM lcnc-relay: <ccatlett1984@> 0.1mm kerf is about beam size assuming we are talking about diode
09:04 PM lcnc-relay: <ccatlett1984@> exit
09:04 PM lcnc-relay: <ccatlett1984@> lol
09:04 PM lcnc-relay: <ccatlett1984@> wrong window
09:04 PM lcnc-relay: <ccatlett1984@> 😄
09:39 PM roycroft: well that was better, but it did not totally compensate
09:39 PM roycroft: the fit is still a little loose, and i have to go out an cut another piece of plywood to test again
09:39 PM roycroft: so that's a tomorrow thing
09:39 PM xxcoder: cool :)
09:39 PM roycroft: but it's getting close
09:39 PM roycroft: very close
09:40 PM roycroft: and i understand another lightburn "quaint feature" now
09:40 PM xxcoder: whats it
09:42 PM roycroft: er, quaint xtool feature, rather
09:42 PM roycroft: the height adjustment
09:42 PM roycroft: if your material is 5mm thick you set it to 1mm
09:42 PM roycroft: if your material is 8mm thick you set it to 2mm
09:42 PM roycroft: if it's 10mm thick you set it to 3mm
09:44 PM xxcoder: for focus?
10:09 PM roycroft: yes
10:11 PM roycroft: it lowers the laser head by that amount
10:12 PM roycroft: so i'm thinking maybe they don't want one to focus on the center of the material - rather they want the focus in the upper part of it
10:12 PM xxcoder: interesting
10:13 PM roycroft: what i know is that the cuts are a lot crisper now that i've adusted that
10:13 PM xxcoder: I wonder why
10:13 PM xxcoder: on the top rather than middle
10:13 PM roycroft: well as i said earlier, a laser cut is hour glass shaped
10:13 PM roycroft: it's not conical like with a waterjet
10:14 PM roycroft: so if you focus in the center you get a spread cut on both the top and bottom
10:14 PM roycroft: if it's thick material, for appearence sake, focusing above the mid-plane makes for a narrower cut at the top and a wider one at the bottm vs focusing exactly on the mid-plane
10:15 PM roycroft: that is my speculation
10:15 PM xxcoder: I guess it depends on what you want
10:15 PM roycroft: comletely unsubstantiated by anything but my thought process
10:16 PM roycroft: yes
10:16 PM xxcoder: top being perfect as possible, or equal
10:16 PM roycroft: as well, i should imagine that the cut begins at the top and works its way down to the bottom
10:17 PM roycroft: so the top would be hotter, as it has had more continuous exposure to the laser
10:17 PM roycroft: and so would be a wider cut, all other factors being equal
10:18 PM roycroft: so focusing nearer the top may mitigate that such that the top and bottom are near equal in the end
10:18 PM roycroft: i'll have to experiment with thicker material, like 19mm, to see what the edge profile is
10:18 PM xxcoder: hmm it does seem to make sense, but of course thinking and actual thing is two different hings
10:18 PM xxcoder: things
10:18 PM roycroft: with 5mm material it's too hard to measure
10:19 PM roycroft: xtool do not explain it
10:19 PM roycroft: they just tell you how to set it
10:19 PM roycroft: but they're a clever company, and i do not believe that they came up with arbitrary settings
10:22 PM xxcoder: yeah
10:22 PM roycroft: and btw, i can now cut 5mm plywood at 80% power in 2 passes
10:23 PM roycroft: it was taking 7 passes at 100% before
10:23 PM roycroft: so that focus setting really made a big difference
10:23 PM xxcoder: makes sense, if it was too wide and wasting energy
10:23 PM xxcoder: I bet less burn marks too
10:23 PM roycroft: yes, less charring, narrower kerf, cleaner overall
10:24 PM roycroft: it also tells me i may be able to cut 19mm plywood fairly easily
10:24 PM roycroft: that may come in handy for making jigs/templates
10:25 PM xxcoder: I bet
