01:42 AM Deejay: moin
01:49 AM randy: g'monring
01:49 AM randy: morning. ... m(
04:28 AM Tom_L: morning
05:00 AM JT-Cave: morning
07:20 AM Loetmichel: anyone here thats good with Moi3d? how can i make a freeform surface of 3 arcs that make an outline?
07:27 AM Tom_L: lofted or nurbs surface?
07:28 AM Loetmichel: nurbs
07:30 AM Tom_L: extrude: http://moi3d.com/forum/lmessages.php?webtag=MOI&msg=1313.2
07:32 AM Tom_L: basically a bunch of bsplines on a grid
07:32 AM Tom_L: nurbs= non uniformal bspline
07:37 AM Tom_L: scan the part with a probe in linuxcnc :)
07:42 AM Loetmichel: Tom: i'll have to "repair" a corner of three intersecting fillets
07:42 AM Loetmichel: i just need a surface to close that corner
07:46 AM Tom_L: fillets can be finicky
07:46 AM Tom_L: in catia depending how i select them i get different results
07:48 AM Tom_L: sounds like fillets may be a little weak in moi3d
07:52 AM Tom_L: can you draw a curve in the 3 planes and extract it that way?
07:52 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/practice_drawings/problem27.jpg
07:52 AM Tom_L: example: that inside corner where 3 come together
07:53 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=18032&g2_imageViewsIndex=1 <- have a little hole there
07:54 AM Tom_L: can you extend that 'tube' then do a surface cut with the other one, then blend them with a fillet?
07:54 AM Loetmichel: yeah, that would work
07:55 AM Tom_L: probably the easiest bet
07:58 AM Tom_L: does it support multi radius blends?
07:58 AM Tom_L: if needed...
08:06 AM unterhaus_: Tom_L, you have made the big time, youtube puts your videos on their home page for me
08:19 AM Tom_L: what?
08:23 AM unterhaus_: when I type in "youtube.com" I see some of your videos
08:30 AM Tom_L: they're desperate
08:30 AM XXCoder: doesnt show in mine
08:30 AM XXCoder: probably due to already watch em all
08:30 AM Tom_L: it's an association of what he watches
08:39 AM Loetmichel: ... niiiice... somehere here in the industrial zone someone is using waaaay too much power... all the flourescents on the ceiling are flickering in unison in a distinct rythm :(
08:39 AM perry_j1987: aliens are coming
09:01 AM Loetmichel: ... aaand they shorted the grid... THAT was a clear fuse blow. half a second of every Flourescent going off and back on... and a few PCs rebooting. Nicely done, neighbor!
09:44 AM aaroncnc: Loetmichel, that sucks, one thing i am glad i invested in was ups for all my pcs and network gear. this year had been bad here with black out once a month lasting from hours to days. And i hate to start my generators only to find one of my pc is dead. Hopefully yours are fine.
09:44 AM Loetmichel: aaroncnc: thats a thing that happens maybe every decade or so here.
09:44 AM Loetmichel: german grind is pretty stable
09:45 AM Loetmichel: so ups isnt that much of a need
09:49 AM aaroncnc: Loetmichel, i used to think the grid here in the USA Michigan area was good. growing up i can only remember one black out. but these days its been terrible.
11:41 AM roycroft: Grrr. I'm kind of screwed. My primary iMac is getting really sluggish, which happens as the "fusion" drive ages. I want to install an external SSD to boot off of and run the machine. That's very commonly done with iMacs, and gives a significant performance increase.
11:43 AM XXCoder: backup
11:43 AM roycroft: The problem is that my iMac has a Thuderbolt 2 interface, which was fairly short-lived, as Thunderbolt 3 came out shortly thereafter, and it's become difficult to find Thunderbolt 2 drive enclosures, other than some expensive RAID enclosures.
11:43 AM roycroft: What I was hoping to be a <$300 upgrade may cost more like $500
11:43 AM roycroft: or even more
11:58 AM rs[m]: roycroft: isn't this stuff somewhat compatible? AFAIK thunderbolt is kind of display port intermingled with pci express on a mini display port connector
11:59 AM XXCoder: i wonder if just upgrading computer would be cheaper at some point
12:00 PM rs[m]: roycroft: AFAIK a "stupid" adapter that just interfaces the different connectors (USB-C on thunderbolt 3 and up vs. mini-dp) should be sufficient
12:07 PM roycroft: Thunderbolt is kind of pcie + display port, yes
12:07 PM roycroft: The problem is that I have Thunderbolt 2, and the connector is different to Thunderbolt 3
12:08 PM roycroft: I'm still looking for a good adapter/drive enclosure that doesn't slow things down
12:09 PM roycroft: And my boss must be having a difficult day again. He emailed me a few minutes ago asking me to change a customer's mailing address in our domain registration database. I went to do that, and found that the address is already set to what the customer requested.
12:10 PM roycroft: I reported this back to my boss and he responded "Yes, I changed that early this morning."
12:48 PM Tom_L: Loetmichel, you get your gap filled with putty?
01:16 PM Tom_L: mmm overnite low 28F
01:37 PM Toneloc: I have an old Bungard CCD\2 PCB milling machine in an untested state, I believe it is tied to proprietary software, I'm thinking of removing it's control board and fitting something like this, does anyone know if these are any good?>> https://www.banggood.com/TWO-TREES-UNO-CNC-Kit-with-Controller-+-Shield-+-Nema-23-Stepper-Motors-+-T...
01:38 PM rs[m]: roycroft: even apple sells such an adapter
01:40 PM Toneloc: Sorry guys, link fixed> https://www.banggood.com/TWO-TREES-UNO-CNC-Kit-with-Controller-+-Shield-+-Nema-23-Stepper-Motors-+-TB6600-+-Limited-Switches-p-1679143.html
02:08 PM roycroft: Apple sell Thunderbolt 3 to USB cables
02:08 PM unterhaus_: Toneloc, if you are interested in linuxcnc, that's not going to work
02:09 PM roycroft: They do also a Thunderbolt 2 to Thunderbolt 3 adapter, but it's the wrong way
02:09 PM roycroft: It is for using Thunderbolt 2 devices with a Mac that has a Thunderbolt 3 port
02:09 PM roycroft: My iMac has a Thunderbolt 2 port
02:09 PM roycroft: I need to go the other way
02:09 PM rs[m]: The Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter lets you connect Thunderbolt and Thunderbolt 2 devices — such as external hard drives and Thunderbolt docks — to any of the Thunderbolt 3 (USB-C) / USB 4 ports on your Mac.
02:09 PM rs[m]: As a bidirectional adapter, it can also connect new Thunderbolt 3 devices to a Mac with a Thunderbolt or Thunderbolt 2 port and macOS Sierra or later.
02:11 PM roycroft: Which one is that?
02:11 PM rs[m]: https://www.apple.com/shop/product/MMEL2AM/A/thunderbolt-3-usb-c-to-thunderbolt-2-adapter
02:11 PM roycroft: Nice. Thanks - I did not see that one.
02:12 PM roycroft: I can probably make that work.
02:13 PM roycroft: I wonder if it works for hard drives as well - some of the adapters only support displays
02:13 PM roycroft: I'll contact Apple and see what they say
02:13 PM roycroft: After they say I should get a new iMac
02:33 PM JT-Shop: sweet I just sold my Miller Millermatic 212 + spool gun for $3k
02:38 PM tiwake[m]: that seems high
02:38 PM tiwake[m]: got my 211 for $1k
02:42 PM JT-Shop: that retails for $.6k
02:42 PM JT-Shop: $4.6k
02:42 PM tiwake[m]: hmm
02:42 PM JT-Shop: when you add the spool gun and mobility cart it adds $1500 or so
02:43 PM tiwake[m]: yeah, that is expensive
02:43 PM tiwake[m]: oh, the cart too?
02:43 PM tiwake[m]: today I got the 7i96 and pi4 today
02:43 PM JT-Shop: the 212 by itself is $2800 or so
02:44 PM tiwake[m]: and a cheapass keyboard
02:44 PM tiwake[m]: need a computer screen
02:44 PM JT-Shop: https://semo.craigslist.org/tls/d/poplar-bluff-miller-212-mig-welder/7404510121.html
02:45 PM JT-Shop: plug it into the lan and ssh into the pi4 after setting it up a bit
02:47 PM JT-Shop: damn I need to clean my desk off!
02:54 PM * Tom_L gives JT-Shop an industrial scoop
02:54 PM JT-Shop: too bad I sold my John Deere 350 dozer...
02:55 PM Tom_L: that would do the trick
02:57 PM JT-Shop: at least we are about done with the Kawasaki assembly machine... a few more tweaks to the nest
02:59 PM JT-Shop: projects are down to 5!
03:02 PM roycroft: So far Apple don't seem to be able to tell me if that adapter will work or not
03:02 PM roycroft: But they did tell me I can get a nice trade-in credit on my old iMac if I buy a new one!
03:08 PM JT-Shop: wasn't that nice of them
03:09 PM Tom_L: you should take them up on that great offer
03:10 PM perry_j1987: bout time for me to get a new macbook pro
03:10 PM perry_j1987: this mid 2012 one i got is still running strong though
03:11 PM roycroft: I already checked - I'd get about $400
03:11 PM roycroft: And a new iMac would cost me upwards of $2500
03:12 PM Tom_L: and what would they do with yours?
03:12 PM roycroft: I have no idea - it's too old for them to refurb and resell at this point.
03:12 PM roycroft: I think they would just recycle it, and know that even with the trade-in, they still made money on the new iMac
03:13 PM Tom_L: 3rd world sales
03:13 PM Tom_L: what do they do with all the trade in cell phones?
03:13 PM Tom_L: same thing probably
03:13 PM roycroft: But someone at Apple just told me that, while my usage is not supported, will pass the usb-c signals through to the Thunderbolt 2 port on my iMac
03:14 PM roycroft: When I was getting new phones on a semi-regular basis I would donate the old ones to the local women's shelter
03:14 PM roycroft: they would issue them to battered women for emergency calling
03:14 PM Tom_L: yeah i recall that
03:14 PM roycroft: But I don't do that any more, because I keep my phone until it no longer works now
03:19 PM roycroft: I might just bite the bullet and go for an internal ssd
03:19 PM roycroft: I've dismantled iPhones and MacBook Pros before
03:19 PM roycroft: I'm always a little scared when I dismantle one of those devices, but I think I can do it without breaking anything.
03:20 PM Tom_L: and if you do you know you can get $400 for it
03:23 PM tiwake[m]: alright, I should be getting the computer screen I bought for the pi4 today
03:24 PM tiwake[m]: need to linuxcnc it up
03:24 PM tiwake[m]: also, what sort of ethernet cable do I need to make for the 7i96? to interface with the pi4
03:27 PM Tom_L: regular ethernet patch cord
03:28 PM tiwake[m]: alright
03:29 PM tiwake[m]: Tom_L: how long can it be?
03:30 PM tiwake[m]: standard ethernet lengths for gigabit ethernet cord?
03:30 PM tiwake[m]: (300' if I recall)
03:36 PM Tom_L: how long do you want it to be?
03:38 PM tiwake[m]: iunno... lul
03:38 PM tiwake[m]: probably a few inches
03:43 PM * JT-Shop punches out for the day and starts to clean the desk off
03:53 PM tiwake[m]: got the computer screen now woo :3
04:11 PM roycroft: It is almost the weekend, indeed.
04:14 PM CaptHindsight[m]: Toneloc: what are you going to use it for?
04:18 PM CaptHindsight[m]: https://www.bungard.de/en/machines/cnc-machines/ccd-2-eco controlling this??
04:18 PM CaptHindsight[m]: you can reuse the current stepper motors
04:18 PM CaptHindsight[m]: post pics of the stepper drives to see if you can reuse them as well
04:19 PM CaptHindsight[m]: skunkworks: did you get snow or rain today?
04:19 PM CaptHindsight[m]: just nonstick light flurries here
04:20 PM roycroft: it's 18 here today
04:21 PM roycroft: balmy, spring-like weather again
04:21 PM roycroft: yesterdayit got up to 20 - the record for the day is 21, so we came close to that
04:25 PM CaptHindsight[m]: same here last weekend, spring like
04:25 PM CaptHindsight[m]: going down to 20F here Sunday -7C
04:26 PM CaptHindsight[m]: last year we had a few inches of snow on Halloween
04:26 PM roycroft: we'll be down in single digits next week
04:26 PM roycroft: much more seasonable
04:26 PM roycroft: the average high for this time of year is around 12
04:26 PM CaptHindsight[m]: maybe by Thanksgiving this year
04:28 PM CaptHindsight[m]: northern Wi had a blizzard warning
04:29 PM CaptHindsight[m]: not sure if it reached Skunkworks
04:39 PM roycroft: We haven't had a frost yet
04:43 PM CaptHindsight[m]: I found an older 32b Athlon dual core cpu and board in my old stuff stack
04:43 PM CaptHindsight[m]: not sure if i should bother with LCNC on it
04:51 PM * JT-Shop listens to Buffalo Springfield
04:53 PM Tom_L: don't know that one
04:55 PM roycroft: i'm a bit too young to have seen them in concert, but i've seen almost all the members of buffalo springfield perform
05:01 PM JT-Shop: https://en.wikipedia.org/wiki/Buffalo_Springfield
05:12 PM JT-Shop: I think a solution for the BP to use the Micro ITX with the damaged PCI bus is to find a 7i92 that's floating around here somewhere as the J1900 has dual NIC's
05:13 PM JT-Shop: now where is that 7i92?
05:15 PM Tom_L: is that stills of crosby stills nash & young?
05:16 PM JT-Shop: yes
05:17 PM JT-Shop: After several drug-related arrests and line-up changes, the group disbanded in 1968. Stephen Stills went on to form the supergroup Crosby, Stills & Nash with David Crosby of the Byrds and Graham Nash of The Hollies. Neil Young launched his solo career and later joined Stills in Crosby, Stills, Nash & Young in 1969.
05:19 PM roycroft: jim messina was in the band at the end as well
05:20 PM roycroft: whom i have seen in concert, as well as cnsy and various permutations of those four, several times
05:22 PM roycroft: i've also seen richie furay, when he did a solo tour a few years ago, and saw bruce palmer in the '80s when he was part of neil young's band
05:32 PM JT-Cave: I've only been to a couple of concerts in my life
05:32 PM * JT-Cave thinks that if I clean up enough down here I can find the 7i92... I found the bag so it must be down here
05:35 PM Tom_L: palmer of emmerson lake & palmer?
05:38 PM roycroft: i used to go to concerts at least monthly
05:38 PM roycroft: for years and years
05:39 PM Loetmichel: Tom_L: nope, had our designer "repair" the file. Quote:"thats faster if i do it this time than to explain to you where you went wrong"
05:39 PM roycroft: and no, that would be carl palmer
06:15 PM tiwake[m]: can linuxCNC be installed to the pi4 from a debian install by changing repos?
06:16 PM tiwake[m]: or adding a repo
06:16 PM Tom_L: i'd use the iso and then update to 2.8.2
06:16 PM Tom_L: personally i think it's easier
06:17 PM Tom_L: http://linuxcnc.org/downloads/ 2.8.1
06:17 PM tiwake[m]: USB boot and install?
06:17 PM Tom_L: then uninstall that and get the deb from buildbot for 2.8.2
06:18 PM tiwake[m]: wait, what?
06:18 PM Tom_L: put that image on a sd card
06:18 PM Tom_L: LinuxCNC 2.8.1 Raspberry Pi OS based on Debian 10 Buster
06:18 PM Tom_L: then since that's a 'pre' version, uninstall it
06:19 PM Tom_L: then get http://buildbot.linuxcnc.org/dists/buster/2.8-rtpreempt/binary-armhf/
06:19 PM Tom_L: the deb from there and install it
06:20 PM Tom_L: then change your sources list to reflect buster 2.8.2
06:20 PM tiwake[m]: so I can't just change repos if debian is already installed?
06:21 PM Tom_L: maybe but i'm not a linux guru so i'm telling you what i did
06:21 PM Tom_L: do you have preempt-rt installed too?
06:21 PM Tom_L: or just debian
06:26 PM CaptHindsight[m]: it might be more work, I haven't tried
06:26 PM Tom_L: took me ~30 min or so iirc
06:27 PM CaptHindsight[m]: only takes a few minutes vs many many of trying
06:27 PM CaptHindsight[m]: same for if i make a mistake installing i just reinstall vs try to fix
06:28 PM CaptHindsight[m]: ^^ what tom says
06:28 PM Tom_L: it's just quicker
06:28 PM Tom_L: unless you're just a glutten for punishment
06:29 PM tiwake[m]: iunno, it came with a net-boot like image with an easy way to install a few different things including base debian with X
06:30 PM Tom_L: so take the road less travelled.. it will be an adventure
06:37 PM Tom_L: on the buildbot site, buster isn't listed in the table but it is in the repo
06:37 PM Tom_L: for 2.8 anyway
06:37 PM Tom_L: just use the one for stretch and change to buster
06:38 PM Tom_L: somebody should add it
06:38 PM tiwake[m]: I never can remember the names of the different debian and ubuntu releases
06:38 PM tiwake[m]: I use manjaro now :P
06:39 PM Tom_L: all toystory characters
06:39 PM tiwake[m]: when I was using debian, I generally changed the repo to testing
06:39 PM Tom_L: bullseye is 11
06:40 PM tiwake[m]: which got me something close to a rolling release
06:40 PM Tom_L: sid is unstable
06:40 PM CaptHindsight[m]: what I like about Debian is how they never mention the number and the name of the version at the same time
06:40 PM tiwake[m]: no shit
06:41 PM CaptHindsight[m]: I think Debian 10 is Buster and 11 is Bullcrap
06:41 PM Tom_L: https://people.debian.org/~miriam/toy_story/
06:41 PM Tom_L: haha
06:42 PM Tom_L: https://electrictoolbox.com/debian-release-names/
06:42 PM Tom_L: should be a full list
06:42 PM CaptHindsight[m]: and then there is always Sid
06:43 PM Tom_L: that one stays the same even though versions change
06:44 PM tiwake[m]: or just testing, which is the next release, between sid and whatever the crap they decide to name the next thing
06:44 PM CaptHindsight[m]: I might still have Buzz on a set of floppies
06:44 PM CaptHindsight[m]: purchased from microcenter
06:44 PM Tom_L: i think they started to use it with linuxcnc around lenny
06:44 PM tiwake[m]: https://www.debian.org/releases/ for a more official name list
06:44 PM Tom_L: i don't remember squeeze
06:45 PM Tom_L: but i'm running wheezy
06:45 PM tiwake[m]: I guess testing right now would be bookworm
06:46 PM Tom_L: and soon linuxcnc will be an installable debian package
06:46 PM Tom_L: currently in the works
06:56 PM CaptHindsight[m]: I hope they don't break RTAI or make things worse to build from scratch
06:56 PM tiwake[m]: they?
06:56 PM Tom_L: the developers
06:56 PM tiwake[m]: the linuxCNC devs?
06:56 PM CaptHindsight[m]: whomever
06:56 PM Tom_L: not me for sure :)
06:56 PM Tom_L: i wish somebody would change the online docs to expanded by default
06:56 PM Tom_L: they used to be
06:58 PM roycroft: I figured it was time to invest in a bigger one, which should have been around $45-$50
06:58 PM roycroft: I've priced them over time, so I had a reasonable expectation that I would be paying that much
06:58 PM roycroft: When I went to Jerry's, the only brand they had was Milwaukee, and it was $138.95
06:59 PM roycroft: Needless to say, I ended up not buying that step drill
07:01 PM Tom_L: i got the smaller one from HD a while back but iirc the bigger one there was around 80ish
07:01 PM Tom_L: same brand
07:01 PM CaptHindsight[m]: mill it
07:01 PM roycroft: I ended up going to 7/8" with the good one I have, used a S&D 15/16" for the next step, then used a round file to finish it
07:01 PM roycroft: i had two holes to drill that size
07:01 PM Loetmichel: Step drills are fine
07:02 PM roycroft: Yes, they are, but not at that price
07:02 PM Tom_L: https://www.homedepot.com/p/Milwaukee-7-8-in-1-1-8-in-9-Black-Oxide-Step-Drill-Bit-2-Steps-48-89-9209/204312646
07:02 PM roycroft: I like them for sheet metal a lot
07:02 PM Loetmichel: but especially for electric cabinets i would use those "punch and die" with the bolt in the middle and the axial bearing under the nut
07:02 PM Loetmichel: sets
07:02 PM macgalempsy: evening folks
07:02 PM roycroft: Yeah, that's the one I was looking at
07:02 PM roycroft: and Jerry's are usually at or below HD prices
07:02 PM roycroft: They must have screwed up
07:03 PM Tom_L: i got the smaller one for something
07:03 PM roycroft: I have a hydraulic chassis punch that I use for conduit openings
07:03 PM roycroft: But I needed a different size hole than my punch dies will cut
07:03 PM Loetmichel: https://werkzeugspezialist.de/blechlocher-kugellager-25-0-mm-format <- those
07:03 PM roycroft: The conduit openings come later
07:04 PM roycroft: And I could not mill the holes because this junction box is part of my mill, and I need to finish it before my mill will work again
07:04 PM roycroft: Those step drills do not work well in SS, though
07:05 PM roycroft: I use carbide hole saws for that, when it's something that's non-precision
07:06 PM Loetmichel: step drills AND hole saws have the problem that they are using way to much torque for the average battery drill
07:06 PM Loetmichel: so i like to drill a small 10mm hole and then use those punch and die things
07:06 PM Loetmichel: its faster and you dont have to recharge the battery drill so often :)
07:06 PM roycroft: I was using my drill press for this
07:07 PM Loetmichel: i thought you said it is part of your milling machine?
07:07 PM roycroft: These holes were 1"/25.4mm in diameter
07:07 PM roycroft: the junction box is for the milling machine
07:07 PM Loetmichel: is it not yet mounted?
07:07 PM roycroft: it is not yet mounted
07:07 PM Loetmichel: ok, then a step drill is a viable solution
07:07 PM Loetmichel: just wanted to give advice
07:07 PM roycroft: I just replaced the spindle motor and controller on the milling machine
07:08 PM roycroft: and I had to redo all the electrics
07:09 PM Loetmichel: that usually ends with me using copious amounts of electrical tape and the solem vow to "clean that mess up later" ;)
07:09 PM roycroft: It's a lot of work not having a milling machine - it took me about 3 hours to make the front plate for this junction box, as I had to use drills, a fret saw (and a dozen or so blades), and files
07:09 PM roycroft: A cnc milling machine would have made the part in 10 minutes
07:09 PM roycroft: I could have manually machined it in an hour
07:10 PM roycroft: And that also reminds me of my latest supply chain weirdness
07:11 PM roycroft: Lamp sockets for Fender amp style indicators are almost non-existent these days, and 250V versions completely unavailable
07:11 PM roycroft: I liket to use those kinds of indicators on my machines, with LED lamps, and the nice jewel lenses
07:12 PM roycroft: Instead I had to order some semi-ugly neon indicators
07:12 PM roycroft: Guitar shops say they've been unvailable for well over a year
07:22 PM Tom_L: how'd that printed box come out?
07:25 PM roycroft: It came out fine, except I replaced it with this new junction box
07:25 PM roycroft: I can use it on one of my other VFDs though
07:30 PM roycroft: At this point it looks like I'll have my mill back online by next weekend or so - the hall sensor is not here yet, and I'll probably not have the junction box I'm working on painted until Sunday, after which it needs a few days to cure before I install it
07:30 PM XXCoder: roycroft: got your led indictor replacement?
07:31 PM roycroft: No, I have not even thought about that lately, other than fighting with AliExpress to get my money back for the one I returned
07:32 PM roycroft: That's a minor thing - it's not slowing down or stopping anything
07:32 PM XXCoder: yeah was curious though heh
07:32 PM Tom_L: mebbe i should get all fancy and get a tree light
07:32 PM Tom_L: i don't run it unattended though
07:33 PM roycroft: I would not call the way I'll be using my router "unattende"
07:34 PM roycroft: but I won't be standing right in front of it the whole time it's working
07:34 PM macgalempsy: zzz...trying to figure out something to do...
07:34 PM roycroft: I'll be in the same room, monitoring as I do other things
07:34 PM Tom_L: same here
07:34 PM Tom_L: i do venture inside once in a while when i'm pretty sure i know what it's doing
07:35 PM roycroft: Sure - when it's time for a refreshing beverage, or to pay the rent on the previous refreshing beverage
07:35 PM roycroft: But not any kind of prolonged absense
07:36 PM Tom_L: i got my post where i'm pretty sure it's gonna run before trying it but i still dry run once
07:37 PM Tom_L: running dual configs now too
07:37 PM Tom_L: they share the tool table and .var file and that's about it
07:37 PM Tom_L: 46 tools and growing
07:40 PM roycroft: I should imagine I'll be doing dry runs for quite a while before I start trusting myself and my machines to do the right thing
07:41 PM Tom_L: still learning about rotary code
07:42 PM Tom_L: i'm thinking my best option for that is to model in catia and unwrap it then import it to my cad cam
07:44 PM roycroft: I'm still making some pretty fundamental design decisions about my router, but I plan on continuing work on the controller for it, hopefully having some stepper motors with flags on the shafts spinning around before too long
07:44 PM roycroft: And CAM software is what I know the least about in the whole process, which is a big reason I've been revisiting that over the past few days

07:45 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/Tube2.jpg
07:45 PM roycroft: I plan on spending some quality time with PyCAM over the next few days
07:45 PM Tom_L: i need to change the part line
07:46 PM roycroft: Have you used Solidworks much, Tom_L?
07:46 PM Tom_L: i took some classes for catia and the practice drawings they gave me i did all in solidworks as well
07:46 PM Tom_L: i'm more comfortable with catia
07:46 PM CaptHindsight[m]: five more 2.8.2 installs from the same ISO today and they all have blanking on after 10-20 minutes
07:47 PM roycroft: If you had to compare Solidworks and Catia in a couple sentences, what would you say the biggest difference is between the two?
07:47 PM Tom_L: roycroft, http://tom-itx.no-ip.biz:81/~webpage/cnc/practice_drawings/
07:47 PM Tom_L: catia is for big industry
07:47 PM roycroft: So that new ISO did not actually fix the problem, eh?
07:48 PM roycroft: Yes, I know that Catia is designed to scale to large projects better than Solidworks
07:48 PM Tom_L: i have a trackball mouse and with the extra buttons i can pan rotate and zoom without lifting my hand
07:48 PM roycroft: But I'm curious what tha tmeans
07:48 PM Tom_L: i like the mouse layout on catia much better
07:48 PM Tom_L: alot faster for me
07:48 PM roycroft: If it's library management I can see that
07:49 PM Tom_L: full blown catia has alot of stuff in it
07:49 PM roycroft: But are there significant features when doing the modeling work that Catia has that are lacking in Solidworks?
07:49 PM Tom_L: it handles assemblies better
07:49 PM Tom_L: fewer crashes
07:49 PM roycroft: There's no way I'll ever be able to justify or afford a Catia license
07:49 PM roycroft: I'm just curious
07:49 PM Tom_L: no it's big bux
07:49 PM roycroft: Solidworks has a steep price tag for my my budget
07:49 PM Tom_L: it's got alot of workbenches i've not even seen
07:50 PM Tom_L: both my boys took several classes for it and i took a couple
07:51 PM XXCoder: roy wonder if auditing a cad class would make you eligible for solidworks student price
07:52 PM XXCoder: though cant use it for commerical uses
07:52 PM Tom_L: they both have similar basic features
07:52 PM Tom_L: you can't audit it here since it's for industry
07:52 PM XXCoder: oh too bad
07:52 PM Tom_L: and yes you can get a student copy
07:52 PM Tom_L: could at least....
07:53 PM Tom_L: my kid had one for mastercam too
07:53 PM Tom_L: acad.. but i hated acad so i never looked at it
07:54 PM Tom_L: xx i tried :)
07:55 PM Tom_L: supposedly i have a lifetime pass to their lab but i think that's mostly bs
07:55 PM Tom_L: i tried once and they had to renew my key
07:55 PM XXCoder: lol ok
07:55 PM Tom_L: they did but it was a pita
07:55 PM roycroft: I have a Solidworks license
07:55 PM roycroft: It's old (2012), but the software works fine
07:55 PM tiwakepi: debian is installed
07:56 PM Tom_L: pi pi
07:56 PM XXCoder: i have no real cad and cam plans yet. i never got that far with my cnc router
07:56 PM tiwakepi: alright, it looks like I'm using bullseye
07:57 PM tiwakepi: deb http://raspbian.raspberrypi.org/raspbian/ bullseye main contrib non-free rpi
07:57 PM Tom_L: tiwakepi, running preempt-rt?
07:57 PM Tom_L: doubtful if it came from there
07:58 PM Tom_L: now you get to build a kernel
07:59 PM tiwakepi: how?
07:59 PM Tom_L: :)
08:00 PM Tom_L: i did tell you the easy way
08:01 PM Tom_L: roycroft, in fairness to SW i _was_ able to do all the practice drawings with it with no issues
08:02 PM roycroft: Yeah, I glanced at those, and none of them would pose any problem for me
08:02 PM Tom_L: the link i posted has some of them but not all
08:02 PM roycroft: I'm just curious what Catia adds
08:03 PM tiwakepi: I'm distracted at the moment by a bunch of different things, one of those things is food
08:03 PM roycroft: I'd expect better drawing management, and probably a better ability to work with really large files
08:03 PM Tom_L: https://www.scan2cad.com/blog/cad/catia-vs-solidworks/
08:03 PM Tom_L: i haven't read that yet
08:03 PM roycroft: I'm carmelizing some onions at the moment, but otherwise not dealing with dinner quite yet
08:04 PM Tom_L: they're both probably cloud based now
08:04 PM Tom_L: i know i learned on the last version that wasn't
08:04 PM Tom_L: "3d experience"
08:05 PM Tom_L: enova? adds groups to it i think
08:05 PM Tom_L: i never got into that
08:05 PM Tom_L: it has FTNA
08:05 PM Tom_L: functional tolerance and annotation
08:05 PM Tom_L: as part of the model
08:05 PM Tom_L: if you care to use it
08:06 PM Tom_L: layered by department etc
08:06 PM Tom_L: not sure SW has that
08:08 PM Tom_L: some engineers summing up the difference thus: “design an engine in SolidWorks, but design an aircraft in CATIA”.
08:09 PM XXCoder: because it calculates tiolences stacking?
08:10 PM Tom_L: all your dimensions are stored in the model and visibility can be prioritized by department
08:10 PM Tom_L: electrical may see one set, machinists may see another set etc
08:10 PM XXCoder: nice
08:11 PM Tom_L: catia's import export isn't as wide ranged as solidworks
08:12 PM Tom_L: cam tools included but you get your post per machine from a 3rd party
08:13 PM Tom_L: i leaned toward it because most shops around here use it now
08:17 PM Tom_L: https://www.buildercentral.com/catia-vs-solidworks/
08:17 PM Tom_L: maybe a better comparison?
08:18 PM Tom_L: although i think he's partial to SW
08:20 PM Tom_L: they have an office here on campus
08:20 PM Tom_L: as does airbus now
08:23 PM Tom_L: i disagree with him on assemblies
08:30 PM CaptHindsight[m]: never wear a red shirt into space https://www.nbcnews.com/news/us-news/william-shatner-crew-mate-space-flight-killed-small-plane-crash-new-je-rcna5476
08:31 PM CaptHindsight[m]: https://twitter.com/MikeElgan/status/1447910236728139779?ref_src=twsrc%5Etfw
08:35 PM roycroft: I've no immediate plans to travel to outer space
08:35 PM roycroft: I'll keep that in mind though, should my plans change
08:36 PM roycroft: The more I learn about the Shaper Origin, the more conflicted my feelings about whether to get one or not
08:38 PM XXCoder: :( sucks when just suddenly dies
08:41 PM unterhaus_: two guys from my work in Utah died in a small plane crash, apparently they were doing terrain following
08:41 PM roycroft: bummer
08:41 PM unterhaus_: the bad influence of working on fighters
08:42 PM XXCoder: whats terrain following? i guess try to set to certain height from ground?
08:45 PM unterhaus_: yeah, stay close to the ground as the ground changes height
08:45 PM XXCoder: geez
08:46 PM unterhaus_: it's useful if someone wants to shoot you, but not so much if you are just out playing around in a private airplane
08:47 PM unterhaus_: they could have worked on my terrain following program and they might have gotten a flight
08:48 PM roycroft: wow
08:48 PM roycroft: homer plessy is being pardoned
08:49 PM roycroft: I guess Louisiana are trying to fix things
08:49 PM XXCoder: 130 years
08:49 PM XXCoder: yeah
08:50 PM roycroft: Best to do the right thing in the first place, of course, but that notwithstanding, beter late than never
08:50 PM XXCoder: yep
10:59 PM t4nk_freenode: I've taken my machine apart for a bit... nice to see where all the problems are
10:59 PM t4nk_freenode: a bunch of them, too
11:01 PM t4nk_freenode: z assembly has survived the onslaught pretty well
11:02 PM t4nk_freenode: z-stepper bbroke off on one side too, hadn't even noticed
11:02 PM t4nk_freenode: the mount that is
11:02 PM Tom_L: must be a flimzy mount
11:03 PM t4nk_freenode: sure, I made it myself ;)
11:03 PM t4nk_freenode: had the same with the other stepper mounts.. until I fixed 'em good
11:04 PM t4nk_freenode: I tightened the x-axis leadscrew holder.. but it
11:04 PM t4nk_freenode: s gone
11:05 PM t4nk_freenode: too small, same thing as with the stepper mounts.. I have designed much stronger ones since
11:05 PM t4nk_freenode: but this was still the old one
11:07 PM t4nk_freenode: well, the good news is that it can be fixed up
