01:03 AM roycroft: well my second go with the vinyl cutter went even better
01:13 AM roycroft: i'm pretty impressed with how well it works for how cheap it is (even if i paid for it)
01:13 AM XXCoder: nice
01:13 AM roycroft: yeah
01:13 AM roycroft: i backed off the knife pressure by 20g and now it weeds even easier than the first time
01:13 AM roycroft: i also went down to get my paycheck today and my boss gave a partial roll of magnetic backed vinyl that they use in their banner printer
01:13 AM roycroft: i'm going to use it to stencil on - it has a nice, smooth, matte white finis on the front
01:13 AM roycroft: i think it should be perfect for stenciling on
01:15 AM roycroft: i've been planning on starting a small signmaking business to generate some income while i'm building the main woodworking business
01:15 AM roycroft: the thought was that i could make signs with the cnc router when i get it built
01:15 AM roycroft: but in truth, i could even start making signs with this vinyl cutter
01:15 AM roycroft: i hadn't thought about that at all when i got it
01:15 AM roycroft: i was just looking for a way to do some in-house graphics work for cheap
01:16 AM Deejay: moin
01:46 AM XXCoder: roycroft: it was cheaper than you expected but yeah lol

03:05 AM randy: morning
04:15 AM travis_farmer[m]: G'Morning, i may have some Paying work today! :-)
04:25 AM travis_farmer[m]: or not... (tomorrow) :-(
04:51 AM JT-Cave: morning
04:52 AM Tom_L: morning
05:14 AM travis_farmer[m]: so, i was checking out: http://tom-itx.no-ip.biz:81/~webpage/emc/xilinx/xilinx14_install_index.php and noticed that it looks like the Xilinx Design Suite is no longer free? i was going to check it out as a matter of curiosity...
05:20 AM jpa-: travis_farmer[m]: you need to request a free license
05:20 AM travis_farmer[m]: Hmm, ok
05:21 AM jpa-: also if you are on modern linux, installation of ISE is a bit annoying
05:22 AM jpa-: hmm no, actually i think xilinx was fine actually
05:42 AM rmu: I installed 14.7 on ubuntu 18.04 i think, and it still works after upgrading to ubuntu 22.04, except for that emoji ttf libpng jumpbuf issue
05:47 AM sensille: ISE on arch linux wasn't hard either
05:56 AM travis_farmer[m]: hmm, 15.5GB download... this could take a while...
06:01 AM mrec: 15gb? I think it will need 120-140gb installed
06:02 AM sensille: not ISE. vivado has grown out of proportion, though
06:02 AM travis_farmer[m]: and here i only have a little over 300GB of free space
06:03 AM mrec: sensille: you cannot deselect vivado anymore no?
06:03 AM sensille: 11215480 Xilinx
06:03 AM sensille: (in kB)
06:04 AM sensille: ISE 14.7
06:04 AM sensille: mrec: ISE and vivado are separate
06:04 AM mrec: okok I only tried vivado but when I saw >100 gb I dumped it for now
06:05 AM sensille: older vivado version are much smaller
06:05 AM sensille: and you don't have to install everything
07:28 AM travis_farmer[m]: well, ISE would not install due to a missing file error... so i gave up on the curiosity and deleted it to save hard drive space
07:39 AM perry_j1987: morning
07:44 AM JT-Cave: hmmm https://raspi.debian.net/daily-images/
07:45 AM * travis_farmer[m] wonders if pcw-home is available
07:50 AM travis_farmer[m]: looks like the discord bridge is down...
07:53 AM * JT-Cave goes to start his chicken day
08:18 AM travis_farmer[m]: posted my issue on the forum, when pcw-home happens to get a minute: https://forum.linuxcnc.org/27-driver-boards/48180-looking-for-firmware-for-a-7i80hd-16-25-for-sserial-x8-7i44-with-stepgens
08:44 AM pcw-home: What stepgen daughteboard?
08:45 AM travis_farmer[m]: straight to the stepper drivers opto inputs, so pin placement isn't critical
08:47 AM travis_farmer[m]: i was using svst8_4 before getting the sserial boards, if it makes a difference
08:48 AM travis_farmer[m]: crap timing on my part... work just called and i gotta go in to work now...
08:50 AM pcw-home: sssvst8_8_8 should be close
08:53 AM JT-Cave: that has pwm on 1 and 2 and ss on 3
08:55 AM pcw-home: Yeah, I can make one closer to SVST8_4
09:10 AM rmu: can't really speak for travis, but yesterday he said
09:10 AM rmu: 22:57:10 travis_farmer[m] | ok, i flashed my 7i80HD-25 (my backup board) with 7i80hd_25_sssvst8_8_8.bit (same thing, but for the 25), so i can test with that before making changes to my board in my control cabinet
09:11 AM rmu: and this https://libera.ems.host/_matrix/media/v3/download/matrix.org/wlTrRvLAMuAilvcUUhYahnNu/7i80hd_25_sssvst8_8_8.pin.txt
09:11 AM rmu: no stepgens
09:32 AM JT-Shop: anyone have a SPINx1 they are not using?
09:59 AM roguish[m]: JT-Shop: is it for you to use, or to sell /??
10:00 AM JT-Shop: a customer needs one
10:03 AM roguish[m]: I have one installed, but it's not in use. was for the spindle vfd, but now I use modbus for the vfd.
10:12 AM JT-Cave: I'll email you his email
10:26 AM JT-Shop: gotta go to work now :(
10:31 AM roguish[m]: JT-Shop: go easy, you're retired....
10:41 AM JT[m]1: Lol
11:40 AM perry_j1987: its that time again
11:42 AM perry_j1987: time to choose what type of home switches to put on this taig
12:13 PM CloudEvil: perry_j1987: Place a bell on the home location and detect the sound of the bell.
12:14 PM perry_j1987: lol
12:19 PM perry_j1987: what are your thoughts on optical
12:35 PM unterhaus_: I was thinking of using proximity sensors in addition to index
12:40 PM Tom_L: unterhaus_, i forgot what you were building
12:40 PM unterhaus_: everything and nothing
12:40 PM unterhaus_: that was on the bridgeport though
12:58 PM unterhaus_: the 7i96 thinks it's connected, but the pc doesn't
01:00 PM unterhaus_: no, I guess the nmcli device status command can't see that it's a static ip or something
01:00 PM unterhaus_: ping works
01:07 PM unterhaus_: does mesact tell you what firmware is currently installed?
01:30 PM pcw-home: unterhaus_: ping will work if you have the host IP address set to the Mesa card address (you are pinging yourself)
01:30 PM pcw-home: the command "ip a" will report the network setup
01:30 PM unterhaus_: no, host is 11, mesa is 10
01:31 PM unterhaus_: mesact is either lying to me or it can talk to the board
01:32 PM unterhaus_: I guess too many people knew ifconfig so they had to get rid of it for our convenience
01:32 PM pcw-home: does mesaflash --device ethernet --addr 10.10.10.10 work?
01:33 PM unterhaus_: yes
01:35 PM pcw-home: OK so comms work
01:37 PM unterhaus_: I was confident they were working, I was just surprised at the results from the linux command
01:41 PM unterhaus_: pcw-home is a usb port going to power a 7i96 and a 7i73 that aren't doing anything?
01:42 PM pcw-home: With no external load, that's probably OK
01:44 PM unterhaus_: andy's phoenix to smart serial adapter just barely fits on a 7i96
01:45 PM pcw-home: no more than 350 or so mA
01:49 PM * JT[m]1 uploaded an image: (274KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/HyUfkhYuAboKKYHwaDcrLNOz/20230207_134129.jpg >
01:50 PM unterhaus_: is a red led on a 7i73 a bad thing?
01:51 PM pcw-home: I indicates a fault (so if linuxCNC is not running its indication a watchdog fault)
01:51 PM pcw-home: It
01:52 PM XXCoder: lining em up eh jt
01:52 PM XXCoder: finally got the missing wood?
01:53 PM pcw-home: You should get red when linuxCNC is not running and a blinky green when linuxCNC is running
01:55 PM XXCoder: in least it isnt resistor led ;)
01:57 PM JT[m]1: Lol
01:58 PM * c101horse8332[m] uploaded an image: (1620KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/woLgYoQAalzoltRejooXxWbN/IMG_20230207_205658.jpg >
01:58 PM c101horse8332[m]: Dangit
01:58 PM c101horse8332[m]: What was the fix for this again? RMU?
02:00 PM travis_farmer[m]: just got out of work :-)
02:00 PM unterhaus_: at least there is no smoke
02:01 PM c101horse8332[m]: found it
02:02 PM XXCoder: no LER either. light emitting resistors lol
02:02 PM unterhaus_: it would be orange by now
02:15 PM unterhaus_: blinking green now
02:15 PM unterhaus_: I caused mesact to barf, but I'm not sure what I did
02:16 PM unterhaus_: unable to receive an event from the clipboard manager in a reasonable time
02:17 PM rmu: c101horse8332[m]: either upgrade linuxcnc-uspace-dev or remove it
02:18 PM c101horse8332[m]: yeah got it, went back two days in the chat😅
02:18 PM unterhaus_: install the dev pkg first, I think
02:18 PM c101horse8332[m]: when i click the qt dragon sim it shows the qt dragon logo for a second or two
02:19 PM c101horse8332[m]: then threw me an error
02:19 PM c101horse8332[m]: something about pyqt5
02:20 PM unterhaus_: install pyqt5
02:20 PM unterhaus_: or whatever lib it asks for
02:20 PM c101horse8332[m]: ModuleNotFoundError: no module named 'PyQt5'
02:21 PM rmu: starting over?
02:21 PM unterhaus_: if I google debian 11 pyqt5 I immediately find out what to install
02:22 PM unterhaus_: you're going to have to do that several times on a new install.
02:23 PM unterhaus_: i'm not sure how a pi install is different than a pc install
02:23 PM c101horse8332[m]: guess what im trying
02:23 PM * c101horse8332[m] uploaded an image: (1937KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/mTHbpkgAjwQTQGLhWAxQdHCL/IMG_20230207_212255.jpg >
02:24 PM unterhaus_: I just got it from apt
02:24 PM c101horse8332[m]: sudo apt-get install pyqt5?
02:25 PM JT[m]1: sudo apt install python3-pyqt5
02:25 PM unterhaus_: on debian it's apt get python3-pyqt5
02:25 PM unterhaus_: did you consider using google like I suggested?
02:25 PM unterhaus_: listen to JT though
02:27 PM unterhaus_: I managed to find a whole directory of .ngc files that don't properly end
02:27 PM c101horse8332[m]: i am
02:27 PM unterhaus_: I know it can be frustrating, but google will almost always give you the answer
02:29 PM c101horse8332[m]: ik, it sometimes gives me the wrong answer that looks like the right answer
02:37 PM * c101horse8332[m] uploaded an image: (860KiB) < https://libera.ems.host/_matrix/media/v3/download/jauriarts.org/bJSVPLvIMMUxEriTNKsXTYds/IMG_20230207_213612.jpg >
02:37 PM c101horse8332[m]: OH WOULD YOU LOOK AT THAT
02:45 PM rmu: +1
02:59 PM c101horse8332[m]: now im wondering if it was my stupidity that kept probe basic from running on the pi
03:05 PM unclouded_ is now known as unclouded
03:07 PM travis_farmer[m]: just curious if pcw-home has made any headway on my firmware issue. no rush, just curious. :-)
03:13 PM JT-Shop: will you take $1500 cash for the planer? me No him what's your bottom dollar? me make me an offer
03:23 PM roycroft: tell him it will cost him ONE MILLION DOLLARS
03:23 PM roycroft: and see what he counters with
03:23 PM JT-Shop: lol
03:23 PM XXCoder: pinkie to lip time
03:24 PM roycroft: and tell him you have a "laser"
03:24 PM travis_farmer[m]: and sharks
03:25 PM JT-Shop: hmm I need a little T track
03:25 PM roycroft: laser shark do do do do do do
03:25 PM travis_farmer[m]: LMAO
03:26 PM * JT-Shop wonders if he has some laying around or not
03:26 PM JT-Shop: roycroft, did you see the sander circle jig?
03:26 PM roycroft: no
03:26 PM roycroft: i'm making one myself, though
03:26 PM roycroft: that's why i got the diamond gravers
03:28 PM * JT[m]1 uploaded an image: (284KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/rTUbMYihLBWOHusiBfuuYajc/20230204_141225.jpg >
03:28 PM JT-Woodshop: that's upside down, you set the vise stop upside down
03:28 PM * JT[m]1 uploaded an image: (291KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/vWbCsFkDpbUcNtyENxwTdGLJ/20230204_141234.jpg >
03:29 PM roycroft: nice
03:29 PM roycroft: that should work well
03:29 PM JT-Woodshop: easy to make too
03:29 PM roycroft: now you know why you have that perpendicular t-track slot
03:29 PM JT-Woodshop: lol yup
03:34 PM rmu: c101horse8332[m]: probe basic uses VTK for the backplot and that probably has issues on the rpi4
03:35 PM XXCoder: interesting
03:35 PM XXCoder: I saw that video where guy added a stop for sleds on table saw
03:35 PM XXCoder: interesting also. and sled has rear part saw goes in and doesnt go out so its good safety
03:36 PM c101horse8332[m]: so far im happy enough to stop tinkering with it too much now that qtdragon runs in sim(ill try if it wants to run the mill either tomorrow or friday)
03:37 PM c101horse8332[m]: i might try the spare pi4 i have and see if i can fiddle around on that to try stuff out
04:19 PM * JT[m]1 uploaded an image: (259KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/DIKruCWMerpTnBrGJupivWpz/20230207_161811.jpg >
04:22 PM CaptHindsight[m]: What do you use for filling thin and fragile metal components while machining other than wax? Something water soluble would be nice.
04:31 PM perry_j1987: how do you guys think these would work for homing /limit switches https://amzn.to/3HH6bUw
04:40 PM CaptHindsight[m]: perry_j1987: fine without the slotted wheels and until they get clogged with debris
04:41 PM perry_j1987: i picked up a taig ballscrew mill the other day
04:41 PM perry_j1987: playing with adding limit switches to it now
04:43 PM perry_j1987: i have 3 of these i could steal off my other machine's +limits https://amzn.to/3YeJiiq
04:43 PM perry_j1987: CaptHindsight[m] how much volume do you need to fill
04:44 PM CaptHindsight[m]: few liters a part
04:44 PM perry_j1987: how fancy are the voids
04:44 PM perry_j1987: and what type of metal
04:45 PM CaptHindsight[m]: honeycombs
04:45 PM CaptHindsight[m]: open cells
04:45 PM CaptHindsight[m]: SS
04:45 PM perry_j1987: would gallium work?
04:46 PM CaptHindsight[m]: too expensive and toxic
04:49 PM Tom_L: ice
04:49 PM Tom_L: :)
04:50 PM CaptHindsight[m]: ice will melt when it is cut
04:50 PM perry_j1987: make a peltier fixture plate :)
04:51 PM CaptHindsight[m]: won't help where the cutting tool meets the metal and ice
04:52 PM Tom_L: never had to do that but once we used pennies as a dampener
04:52 PM perry_j1987: aye
04:52 PM perry_j1987: ice expands too
04:52 PM CaptHindsight[m]: water soluble polymer will work
04:52 PM Tom_L: bank wasn't so happy when we returned them coolant soaked
04:52 PM XXCoder: hmm is it reusable?
04:53 PM XXCoder: would be lot cheaper if you could just re-solidify or seperate from water and use on next part
04:54 PM Tom_L: why is wax out?
04:54 PM Tom_L: machinable wax even
04:54 PM perry_j1987: thats what im wondering
04:54 PM XXCoder: wax would be meltable, and more importantly, filterable
04:55 PM Tom_L: also may contaminate something we're not aware of
04:55 PM XXCoder: true
04:55 PM XXCoder: cleaning process may be too annoying
04:55 PM Tom_L: i'm not sure how they machine honeycomb
04:55 PM roycroft: 3d print a form with water-soluble filament
04:55 PM Tom_L: generally it has layers on both sides
04:57 PM CaptHindsight[m]: I have water soluble resins, I just tthought that this was a common machinist issue
04:58 PM CaptHindsight[m]: where you need to hold parts with voids and thin features
04:58 PM XXCoder: well just had a thought. pla printed inserts coated with resin
04:59 PM XXCoder: if it pops off in water then majority of it is reusable
04:59 PM CaptHindsight[m]: synthetic ice cream, the type that doesn't melt even at 40C
04:59 PM CaptHindsight[m]: XXCoder: it has to fill the voids in the honeycomb, you can't insert a solid
05:00 PM XXCoder: I was thinking 2d profile hex, ie hex shaped pockets
05:00 PM CaptHindsight[m]: has to be liquid, gel or paste
05:01 PM CaptHindsight[m]: the cells are open so it could be dipped or floated until sunk in the material
05:03 PM CaptHindsight[m]: cure to be strong enough to support the few mills thick walls during machining
05:03 PM CaptHindsight[m]: then completely removed after
05:04 PM travis_farmer[m]: supper has arrived (KFC), signing off for the night :-)
05:04 PM unterhaus_: there is a wax substitute
05:04 PM unterhaus_: I googled it
05:05 PM unterhaus_: Rigidax tooling compound is a castable, thermoplastic material
05:08 PM CaptHindsight[m]: by Boeing
05:10 PM Tom_L: that's one thing we never had to machine
05:12 PM Tom_L: https://machinablewax.com/rigidax-tooling-fixturing-wax/
05:13 PM CaptHindsight[m]: https://machinablewax.com/content/SDS_Rigidax_WS_US_Rev.2.0.pdf
05:14 PM CaptHindsight[m]: Mixture of polyethylene glycol & inorganic fillers.
05:16 PM CaptHindsight[m]: :( "You'll then be left with what looks like a coating of cheap paint on your part that will have to be removed. You can remove the residual wax by mechanical means, "
05:16 PM CaptHindsight[m]: so that won't work
05:16 PM CaptHindsight[m]: FFS, I gotta make this too!
05:18 PM Tom_L: how big is the part?
05:19 PM CaptHindsight[m]: sheets 1" thick, 2ft^2
05:20 PM CaptHindsight[m]: cells are ~0.1" dia
05:20 PM Tom_L: fairly fine

05:24 PM Tom_itx: https://www.youtube.com/watch?v=SKLt_dYTvJA
05:24 PM Tom_itx: they don't seem too concerned
05:25 PM unterhaus_: now I wonder how GD used to machine the honeycomb in the f16 horizontal tails
05:25 PM CaptHindsight[m]: aluminum would make things easier
05:26 PM unterhaus_: I suppose it's possible to just machine it
05:26 PM Tom_itx: composite?
05:26 PM CaptHindsight[m]: SS
05:26 PM Tom_itx: arg
05:26 PM CaptHindsight[m]: yup and really thin
05:26 PM unterhaus_: lasers, pew pew pew
05:28 PM CaptHindsight[m]: unterhaus_: a phaser like Star Trek with selectable cutting depth
05:28 PM CaptHindsight[m]: ok so have to make it
05:28 PM CaptHindsight[m]: how it just goes sometimes
05:28 PM unterhaus_: yes, disapparate the material you don't want
05:30 PM CaptHindsight[m]: who had the disrupters? Klingons?
05:30 PM CaptHindsight[m]: might be handy
05:30 PM CaptHindsight[m]: if they were real
05:30 PM perry_j1987: think the romulans did too
05:31 PM Tom_itx: capn, there are patents for machining honeycomb btw :)
05:31 PM CaptHindsight[m]: https://scifi.stackexchange.com/questions/4246/what-is-the-difference-between-a-phaser-and-a-disruptor
05:31 PM CaptHindsight[m]: Tom_itx: only if somebudy notices
05:32 PM CaptHindsight[m]: what did they patent?
05:32 PM Tom_itx: fixture freezing was one
05:32 PM Tom_itx: https://patents.google.com/?q=B23Q3%2f086
05:33 PM Tom_itx: https://patents.google.com/patent/US2855664A/en
05:34 PM CaptHindsight[m]: 1975-10-14
05:34 PM CaptHindsight[m]: Anticipated expiration
05:35 PM Tom_itx: didn't know if they may disclose how they fixtured it
05:35 PM Tom_itx: freezing was an option though i think
05:36 PM CaptHindsight[m]: maybe a dairy solution
05:36 PM unterhaus_: didn't you have to submit a model back then?
05:36 PM unterhaus_: rotten milk, that's the ticket
05:36 PM Tom_itx: say cheeeessssee
05:36 PM CaptHindsight[m]: tiny cheese, then send it insects and bacteria to clean
05:36 PM unterhaus_: cheese requires compression
05:37 PM Tom_itx: gives it that new product funky smell
05:37 PM unterhaus_: I suppose that could be possible
05:37 PM CaptHindsight[m]: small curd honeycomb reinforcement
05:37 PM Tom_itx: be curious what you figure out on it
05:38 PM CaptHindsight[m]: nature always has something close
05:38 PM unterhaus_: 3d print the honeycomb
05:38 PM CaptHindsight[m]: i have water soluble resins but I am trying to reduce the cost
05:39 PM CaptHindsight[m]: yeah but they aren't yet
05:39 PM CaptHindsight[m]: so it remains a machining problem
05:40 PM CaptHindsight[m]: tapioca
05:41 PM CaptHindsight[m]: starches and sugars
05:41 PM unterhaus_: I feel like any food product that will work is going to be similar to glue
05:41 PM unterhaus_: so cleaning will be a problem
05:42 PM CaptHindsight[m]: hot water rinse
05:42 PM CaptHindsight[m]: PVA sure
05:43 PM unterhaus_: our dog is getting a special canned food for a couple of weeks. I put the can in the dishwasher, and it didn't get clean
05:43 PM unterhaus_: whatever is in that dogfood probably should be sold as glue
05:43 PM CaptHindsight[m]: high carb diet?
05:43 PM unterhaus_: no fat diet
05:43 PM CaptHindsight[m]: ah

06:03 PM xxcoder8265[m]: lol
06:11 PM CaptHindsight[m]: good for a cheese mill or Meringues
07:10 PM bjorkintosh: unterhaus_, the fault might be with the dish washer.
07:16 PM roycroft: especially if she's only 12
07:19 PM bjorkintosh: hahahah
