12:12 AM CaptHindsight[m]: qtpyvcp installs pretty easily in Gentoo now
01:14 AM pere: hi
02:32 AM CaptHindsight[m]: https://www.ge.com/news/reports/atomic-bonding-from-a-bottle-these-scientists-use-3
02:38 AM CaptHindsight[m]: https://research.csiro.au/metals/add-manufacturing/aus-innovation/thermally-assisted-machining/
02:43 AM pere: CaptHindsight[m]: cool
04:34 AM Tom_L: morning
04:43 AM travis_farmer: G'Morning, i feel today "should" be a good day, on my VFD debug :-)
05:03 AM JT-Cave: morning
06:42 AM travis_farmer: supposed to be a little warmer today. it is already up to 19F, and expected to go up to 30F :-)
07:56 AM travis_f[SHOP]: holy crap it is cold in the shop today! good news, i can control my VFD on via RS485... it just doesn't stop...
07:57 AM travis_f[SHOP]: configs at https://github.com/travis-farmer/linuxcnc/tree/master/configs/my_LinuxCNC_router
08:07 AM travis_f[SHOP]: hmmm, something still wrong... heading inside to debug in the heat
08:12 AM travis_farmer: i love SSH over the network... i can edit config files and read where i may have gone wrong, remotely. then head out when the heat has warmed up to test it :-)
08:30 AM saquzi: Hi again.. Now i saw that my encoder seems to not be giving index pulse... it has ABZ, but only the a and b seems to be working. I tried to change A and Z wires on the board the A pulse is coming like it should on the Z but the index wont show in A input still.. could it be a hal issue or fysical issue? tried to flip the index wires, no change. If
08:30 AM saquzi: i index-invert 0-->1 it just changes from constant red to yellow in hal confiquration..
08:31 AM saquzi: If the "gray scale" input is used, the index would not be needed? Can it be that the encoder does really even have the index on itself...
08:32 AM saquzi: http://pico-systems.com/osc2.5/catalog/links/images/fanuc17.pdf pinout seems to match this
08:50 AM JT-Cave: saquzi, https://gnipsel.com/linuxcnc-old/tuning/encoder.html
08:53 AM travis_farmer: well, time to go back out in the cold and test my config changes. i hope the heat has warmed it up to a good working temp.
09:00 AM travis_f[SHOP]: this is very odd... i watched the TX/RX LEDs on my USB/RS485 serial device, and they were working, until the VFD started turning the spindle. then communication stopped. seems like i am getting interference from the VFD.
09:01 AM travis_f[SHOP]: and i can't re-use the serial port again after shutting down LCNC, unless i pull the USB plug out, and back in again...
09:29 AM travis_f[SHOP]: hmmm, even when i shield the RS485 wire, the communication still drops out when the spindle starts turning. and i noticed the at speed indicator on LCNC is blinking, even after the spindle is stopped (via the stop button on the VFD)
09:29 AM JT-Shop: hi ho it's off to work I go
09:29 AM travis_f[SHOP]: enjoy, JT
09:32 AM rmu: travis_f[SHOP]: did you wire RS485 GND in addition to A and B between VFD and PC?
09:32 AM travis_f[SHOP]: yes
09:33 AM rmu: what kind of cable are you using?
09:34 AM travis_f[SHOP]: shielded twisted pair CAT5e
09:36 AM rmu: you could check for bus levels when idle and when idle while running the spindle, it is possible if the bus is floating that glitches can be interpreted as a start bit by the UARTs
09:36 AM travis_f[SHOP]: hang on, let me check...
09:36 AM rmu: funny thing here is, when I start the spindle, the DSL connection to the internet drops immediately...
09:37 AM zephyr9900: I had errors with the VFD RS-485 communications to the PC using shielded twisted pair cable but they went away whan I lowered the baud rate
09:37 AM rmu: waiting for fiber...
09:37 AM travis_f[SHOP]: baud rate is 9600
09:37 AM zephyr9900: Oh that is much slower than mine
09:40 AM rmu: travis_f[SHOP]: if the levels of A and B are all over the place, you could put resistors with around 560 ohms from A to +5V and B to GND
09:40 AM rmu: that fixes the bus to idle in case no sender is active
09:41 AM travis_f[SHOP]: yeah, lots of interference when the VFD starts...
09:42 AM rmu: then put those resistors somewhere on the bus. google "RS485 bus failsafe" should get you some links to PDFs from TI
09:44 AM travis_f[SHOP]: yes, i will... at the moment, my blood sugar levels seem to be falling. (dizzy), i will make a note to add those resistors next session. thanks :-)
09:44 AM zephyr9900: I have STM32CubeIDE installed and I am trying to build the STMBL project. It seems like it is building but there are 2 errors I don't understand: Description Resource Path Location Type
09:44 AM zephyr9900: Program "g++" not found in PATH stmbl_m Project Properties, C++ Preprocessor Include.../Providers, [CDT Cross GCC Built-in Compiler Settings] options C/C++ Scanner Discovery Problem
09:44 AM pere: what about c++ instead of g++?
09:46 AM rmu: isn't stmbl purely a C program? the compiler executable should be called something like arm-none-eabi-gcc
09:47 AM zephyr9900: yes it is. It goes through the whole build and outputs first these 2 errors then proceeds to build everything outputting some warnings and info so it seems like it is actually building.
09:49 AM rmu: travis_farmer: https://www.ti.com/lit/an/slyt324/slyt324.pdf
09:49 AM rmu: (assuming travis_f[SHOP] === travis_farmer)
09:55 AM travis_farmer: yes, this is travis_f[SHOP], and thanks for the link. i will check it out :-)
10:21 AM saquzi: +JT-Cave: If i try to comment "unlink motor.00.index-enable" it says that "Error: unknown command ´unlink´"
10:37 AM zephyr9900: saquizi: do you mean unlinkp ?
10:38 AM zephyr9900: err I mean saquzi
10:39 AM saquzi: tried unlink
10:39 AM zephyr9900: unlinkp
10:59 AM JT-Cave: saquzi, http://linuxcnc.org/docs/stable/html/hal/basic-hal.html
11:20 AM saquzi: So the reason for doing this is to ensure that the index input is working, but some connection in hal is making it not to work?
11:22 AM pcw---home: you can check index without unlinking any pins (by "sets"ing the signal that conveys index-enable)
12:12 PM Tom_L: pcw---home, do you happen to remember what mesaflash version changed board descriptions from 7i80 to 7i80hd-16 etc?
12:12 PM Tom_L: on the cmd line
02:07 PM pere: <URL: https://yewtu.be/watch?v=ib4MXfZPTGg > was fun
02:16 PM zephyr9900: pere: looks nice how many axis?
02:16 PM Tom_L: 9
02:17 PM Tom_L: Yes, 4x X+Z axis + C axis
02:17 PM zephyr9900: and multiple spindles too
02:17 PM zephyr9900: its like 4 lathes on one bed
02:19 PM zephyr9900: can it run more than just one XZ set at a time?
02:27 PM Tom_L: that would likely be up to the cad cam & post
02:28 PM Tom_L: i just hope they numbered all those wires
03:35 PM CaptHindsight[m]: it's similar to the glass lathes
03:36 PM CaptHindsight[m]: you need a bunch of different tools and some at the same time
03:37 PM CaptHindsight[m]: 9 axis is not enough some times
03:45 PM solarwind: CaptHindsight[m] what slicer do you use?
03:46 PM CaptHindsight[m]: modified Slic3r and some others
03:46 PM CaptHindsight[m]: I have to write my own CAM
03:46 PM solarwind: why is that?
03:47 PM CaptHindsight[m]: also some of the built in 3d print tools in NX and Catia
03:47 PM CaptHindsight[m]: there isn't CAM for non-planar printing except for some of the CNC glue gun toys
03:48 PM CaptHindsight[m]: that 5-axis FDM project even uses a modified RhinoCAM
03:48 PM solarwind: You have a 5 axis printer?
03:49 PM roycroft: top
03:49 PM CaptHindsight[m]: I build 5+ axis machines for 3d printing as well as inkjet, airbrush, stylus, laser etc etc
03:50 PM CaptHindsight[m]: and also hybrids that combine different additive and/or cutting tools
03:50 PM solarwind: CaptHindsight[m] have any videos of the 5 axis printer?
03:50 PM CaptHindsight[m]: they look similar to mills
03:51 PM CaptHindsight[m]: posted before https://i.imgur.com/LOriL1y.png pretty sure you have seen these
03:52 PM CaptHindsight[m]: https://imgur.com/gLwOHAg and similar
03:53 PM CaptHindsight[m]: I'm trying to work with freecad/path
03:53 PM solarwind: I haven't seen those
03:54 PM CaptHindsight[m]: ^ for a silicon valley fruit company
03:56 PM CaptHindsight[m]: there just isn't CAM off the shelf for non-planar printing tech
03:56 PM CaptHindsight[m]: so i use a bunch of hacks
03:57 PM CaptHindsight[m]: no CAM to control 1-1,000+ inkjet nozzles passing 1mm over a non-planar surface
03:58 PM CaptHindsight[m]: no CAM for light based tools, like SLA/LCD to cure a resin and also deposit metals while making the 3d parts
03:59 PM CaptHindsight[m]: or even a simple LCD/DLP resin printer that can place metal fasteners into the parts as they are printed
04:00 PM CaptHindsight[m]: or threaded inserts
04:01 PM solarwind: Sigh
04:01 PM solarwind: I could write one
04:02 PM solarwind: Would love to work on something like that
04:02 PM solarwind: My day job is too easy
04:02 PM CaptHindsight[m]: set me up with a job in Toronto
04:03 PM CaptHindsight[m]: I'll keep you busy
04:03 PM solarwind: Are you building these for a company?
04:03 PM solarwind: Or independent contractor?
04:03 PM CaptHindsight[m]: enough job to get my Canadian PR card
04:04 PM CaptHindsight[m]: I make them for anyone with funding
04:04 PM solarwind: I mean do you work for a company that makes the machines, or are you doing it solo?
04:04 PM CaptHindsight[m]: unless they are an open pedo or mafia kingpin
04:05 PM CaptHindsight[m]: I have had my own companies for 40+ years. I offer R&D services
04:05 PM solarwind: ah ok
04:05 PM CaptHindsight[m]: the printer ^^ was $250K about 10 years ago
04:06 PM CaptHindsight[m]: they had their own software devs
04:07 PM CaptHindsight[m]: they ran NX with CAM since they were only placing small amounts of ink onto the surfaces of anodized hand held devices that played music files
04:07 PM CaptHindsight[m]: some sort of media player
04:08 PM * CaptHindsight[m] will trade services for Canadian PR card
04:10 PM roycroft: i have a friend who used to issue honourary canadian citizenship certificates to some of her friends from down in the states
04:10 PM roycroft: but that's while she was living in boulder
04:10 PM roycroft: she got deported a few years ago, and i'm not sure if she's still issuing those certs
04:10 PM roycroft: she became rather bitter after the deportation for some reason
04:11 PM roycroft: i think there was some minor detail like the lack of a visa or green card that she did not take kindly to
04:13 PM solarwind: I don't think we're that strict
04:13 PM CaptHindsight[m]: some guberment people get hung up in details
04:13 PM solarwind: I've never heard of anyone getting deported from canada
04:13 PM solarwind: just pretend you don't speak english
04:14 PM CaptHindsight[m]: solarwind: how long can I hide out in your bunker before they find me?
04:14 PM solarwind: forever haha
04:14 PM solarwind: "immigration issues" is not a talking point hee
04:14 PM solarwind: we have plenty of free healthcare to go around
04:14 PM CaptHindsight[m]: until the trucker convoy
04:15 PM solarwind: those guys were just funny and no one payed attention to them after it was over
04:15 PM solarwind: we were just excited _something_ was happening
04:15 PM CaptHindsight[m]: I am surrounded by those idiots
04:16 PM CaptHindsight[m]: i try not to pop their bubbles
04:18 PM CaptHindsight[m]: https://3dprintingindustry.com/news/mango-3d-makes-lychee-slicer-compatible-with-fdm-3d-printing-218479/
04:19 PM CaptHindsight[m]: but still closed
04:20 PM CaptHindsight[m]: some are so awful that they constantly track the printer and the client user interface
04:20 PM CaptHindsight[m]: we watched the traffic on the firewall after just plugging it in
04:21 PM roycroft: my friend is canadian
04:21 PM roycroft: she got deported from the usa
04:21 PM CaptHindsight[m]: they track just about every mouse click and layer printed
04:22 PM solarwind: I'm just using Cura for now
04:22 PM solarwind: I really need to build myself a cross gantry printer
04:22 PM CaptHindsight[m]: she sounded like a threat against acting un-democratically
04:23 PM solarwind: I just can't get behind CoreXY for some reason
04:23 PM CaptHindsight[m]: how about a binderjet printer?
04:24 PM CaptHindsight[m]: print sand molds or metals
04:24 PM roycroft: you would use that to print binders full of women?
04:24 PM solarwind: https://www.youtube.com/watch?v=vnXzOBuGN74 this is what I'm after ideally
04:24 PM CaptHindsight[m]: sounds restricting
04:25 PM CaptHindsight[m]: belt driven
04:25 PM CaptHindsight[m]: solarwind: how about using linear servos?
04:26 PM solarwind: definitely an option
04:26 PM CaptHindsight[m]: lost of cheap parts on ebay that hardly anyone knows how to use
04:26 PM CaptHindsight[m]: magnets and forcers
04:26 PM CaptHindsight[m]: it's like a circular motor that you unwind and place flat
04:27 PM CaptHindsight[m]: people just can't see it
04:28 PM CaptHindsight[m]: https://www.youtube.com/watch?v=uf_Z57gAJTc
04:29 PM solarwind: https://www.youtube.com/watch?v=K-jtNPig1m8
04:29 PM solarwind: yeah, can't find any suppliers
04:32 PM solarwind: Everything I come across is just a regular stepper/servo attached to a screw or rack and pinion
04:32 PM solarwind: can't find any real linear motors
04:37 PM CaptHindsight[m]: https://www.ebay.com/itm/283862103767 small one
04:38 PM CaptHindsight[m]: https://www.ebay.com/itm/194227672692
04:38 PM CaptHindsight[m]: https://www.ebay.com/itm/224521290471
04:39 PM CaptHindsight[m]: a few YASKAWA
04:40 PM CaptHindsight[m]: also see some Anorad and Aerotec
04:41 PM * travis_farmer loves eBay, but sadly has no money to spend there lately...
04:42 PM CaptHindsight[m]: bog one https://www.ebay.com/itm/401541401656
04:43 PM solarwind: ah the good old travis farmer
04:43 PM travis_farmer: yes?
04:43 PM solarwind: travis crops not doing well this harvest season?
04:44 PM travis_farmer: naw, there seems to be a shortage
04:44 PM CaptHindsight[m]: https://www.ebay.com/itm/261115079849
04:44 PM solarwind: CaptHindsight[m] yeah that's a bit too expensive
04:44 PM solarwind: might as well get the regular leadshine servos and do belt drive
04:44 PM CaptHindsight[m]: solarwind: they move laterally faster than gravity so you should be able to make free floating 3d prints :)
04:45 PM CaptHindsight[m]: but don't you want 3-4G of acceleration?
04:45 PM JT-Shop: hmm a Corvette GRAND SPORT Z16 3LT only gets 27 mpg highway
04:45 PM CaptHindsight[m]: and 1um accuracy
04:45 PM solarwind: you can't get that with the regular leadshine servos?
04:45 PM solarwind: the 400W low inertia servos should be able to manage that
04:45 PM CaptHindsight[m]: with rocket assist
04:46 PM solarwind: https://docs.google.com/spreadsheets/d/1lFiJi-X3Xm3hh3I9Ty9dfACMiBWxHFAOUeiU1km9m6I/edit#gid=106736391
04:47 PM CaptHindsight[m]: solarwind: https://www.youtube.com/watch?v=cF5DHY12bkk
04:47 PM CaptHindsight[m]: solarwind: your parking lots sounds like a great place for a foundry
04:47 PM solarwind: Those guys are doing 10g acceleration on open loop steppers
04:48 PM solarwind: Yeah the 3D printing moulds is something that would interest me
04:48 PM CaptHindsight[m]: yes, but not with as much accuracy
04:48 PM solarwind: not 1µm that's for sure
04:48 PM solarwind: but definitely 100µm
04:49 PM CaptHindsight[m]: vs resin printing a mold and injecting thermoplastics
04:50 PM CaptHindsight[m]: or make a 5+ axis CF knitting machine that also coats the knits with epoxy
04:53 PM CaptHindsight[m]: https://www.youtube.com/watch?v=zQzxJP4ZmiI 3d knit CF auto body panels
04:55 PM CaptHindsight[m]: https://www.youtube.com/watch?v=02h74L1PmaU your CAM
05:54 PM Tom_L: JT-Shop, https://www.youtube.com/watch?v=96HONWynDWA
05:55 PM Plaid1: Is there a way to easily upgrade from debian 10 + lcnc 2.8 to 2.9? Or is that a large task?
05:56 PM Tom_L: 10 is buster?
05:56 PM Plaid1: Yeah
05:56 PM Tom_L: hmm
05:56 PM Plaid1: Like, did I miss an easy upgrade guide?
05:57 PM Plaid1: or is 2.9 still pre-release?
05:57 PM Tom_L: yes
05:57 PM Tom_L: http://buildbot.linuxcnc.org/
05:57 PM Tom_L: http://buildbot.linuxcnc.org/dists/buster/2.9-rtpreempt/binary-amd64/
05:57 PM Tom_L: find the latest one there
05:58 PM Tom_L: alot of those are docs
05:58 PM Tom_L: linuxcnc-uspace_2.9.0~pre1.120.gae4a24b07_amd64.deb
05:59 PM Tom_L: or build it from source
06:07 PM Plaid1: Ah, I see. is 2.9 stable enough I can use it for an actual machine, or should I stick with 2.8? I saw a feature for PID turning that I'd like to try, but it's not worth going "expirmental" if that makes sense.
06:08 PM Tom_L: make a backup
06:08 PM Tom_L: ssd are cheap
06:13 PM Tom_L: XXCoder, https://www.youtube.com/watch?v=T53zdMvOPmE
06:13 PM XXCoder: looking
06:14 PM Tom_L: thought you might...
06:17 PM XXCoder: pressure based grinding. interesting
06:17 PM XXCoder: so it can use most of grind block
06:17 PM XXCoder: I wonder how it comps for length
06:18 PM XXCoder: one thing eh is parts stacking mess. it would result in warning in last shop I worked on
06:24 PM XXCoder: interesting video allright
06:25 PM XXCoder: thanks tom
06:52 PM CaptHindsight[m]: Plaid1: unstable master is now 2.10
06:54 PM roycroft: the really interesting, or at least entertaining, video would be a pakistani bearing plant
06:55 PM Tom_L: roycroft, or an oil filter plant https://www.youtube.com/watch?v=jiKbyi9fEmE
07:00 PM roycroft: that's a fancy factory
07:01 PM roycroft: the workers are wearing shoe-like things
07:01 PM roycroft: in most of the pakistani factories they're barefootin'
07:02 PM Tom_L: you see the turning one i posted for jt?
07:04 PM CaptHindsight[m]: I like the automated set screw installer
07:07 PM CaptHindsight[m]: self centering, not the most precise, but neat video
07:09 PM unterhaus: amazon selling libre 2gb version for $35
07:12 PM zephyr9900: Has anyone built the code for STMBL lately?
07:13 PM unterhaus: probably get a better response to that question on the stmbl channels
07:14 PM zephyr9900: OK thanks
07:17 PM unterhaus: I don't know if there is a better place than the gitter
08:09 PM XXCoder: wow rpi shortage may be ending soon
08:20 PM roycroft: just in time for another shortage :)
08:26 PM XXCoder: probably lol
08:50 PM Bleepshop: Finally!
08:50 PM Bleepshop: Got all the car issues taken care of for the moment and ordered a 7I96S today. :D
08:51 PM Bleepshop: Of course tomorrow it'll eat the throwout bearing or a couple of wheel bearings that are making zero noise today. LOL
09:04 PM Tom_L: optimist
09:08 PM Bleepshop: Hey, it already ate the factory headgaskets, the original suspension and a clutch which is now a nice Stage 2 that won't grenade if I dump the clutch.
09:10 PM Bleepshop: I' 6 bushings away from a complete suspension rebuild and I'm going to do motor and transmission mounts next month to get rid of the Gummi Bears that are there now.
09:11 PM Tom_L: how many miles on it?
09:13 PM Bleepshop: 2002 Outback, 250K+ I just picked it up in July to replace the 95 Legacy wagon with >340K that needed a solid week in the shop.
09:15 PM Bleepshop: The 95 is now the property of a student who only needs to commute to school and the weed store. ;D
09:23 PM * roycroft remebers when school used to be the weed store
09:46 PM CaptHindsight[m]: heh, the gateway drug, "smoke one refer and it's heroine next"
09:47 PM CaptHindsight[m]: s/refer/reefer/
09:47 PM Bleepshop: roycroft: Yerah the principal at the Catholic school always had the best weed. LMAO
09:48 PM Rhine_Labs: I give up what ever i installed keeps locking winblows..
09:48 PM Rhine_Labs: Will reload this bitch..
09:49 PM Rhine_Labs: Did the same think on my laptop when fire fox updated also.
09:49 PM Bleepshop: Rhine_Labs: I thought that's what linux and VMs are for.
09:49 PM CaptHindsight[m]: I had to take 0.003" off a graphite rod, reached for the sandpaper vs the lathe
09:50 PM Rhine_Labs: Yea, Linux is good but sadly this pc requires winblows. \
09:50 PM Bleepshop: Oh look, win-dose crashed again. Reboot the VM and start over. LOL
09:51 PM Rhine_Labs: New build..
09:51 PM Bleepshop: I have exactly one machine that runs windows and all I use it for is playing Fallout and Portal. LOL
09:51 PM Rhine_Labs: Ryzen 9 7900X with RTX3070 \
09:52 PM Rhine_Labs: Sadly my software i use dont run well in a VM
09:53 PM Bleepshop: Well that was your first mistake, Bleeding edge hardware. That's why I stick to whatever I find at the thrift store and slap in RAM and an SSD. XD
09:53 PM Bleepshop: Rhine_Labs: What's the software?
09:54 PM Rhine_Labs: No i think what ever is in Firefox 64bit is the issue did the same thing on my laptop anoying
09:54 PM Rhine_Labs: have the hiot crtl alt del then cancel it out to unlock it
09:54 PM Rhine_Labs: have to hit
09:54 PM Bleepshop: Rhine_Labs: Although to be fair I have in the past used RPi-3s and a Banana Pi M2 as desktop machines for over a year. CAD/Blender/Whatever.
09:55 PM Rhine_Labs: I removed fire fox and chrome lots see if it locks up
09:56 PM XXCoder: bleep I had to use rpi4 for around 50 days before I could fix my pc
09:56 PM XXCoder: so fun
09:56 PM Rhine_Labs: Not fun..
09:58 PM Rhine_Labs: Almost got my Tormach unburied lol. been overwhelmed
10:04 PM Rhine_Labs: still need to get the ducting done for the lasers..
10:17 PM Bleepshop: XXCoder: What's funny is I was running fedora on both of them.
10:17 PM XXCoder: just used stock raspian os
10:20 PM * Bleepshop can see.... Too much. LOL
10:23 PM Bleepshop: I ordered a couple of cheap sets of LED can light retrofits. 6" dia, 900lm for 12w. 12pcs/set. I put up 23 of them since there's a stovepipe where #24 wants to be.
10:26 PM Bleepshop: Little under 600sq/ft of shop. I could perform surgery if the patient wouldn't croak from all the stove ash, soot, dust and mouse crap. LMAO
10:31 PM Bleepshop: And I guess I'm glad I bought them when I did because they're now $50/dozen instead of $24/dozen. https://www.amazon.com/dp/B08MT9GXX6
10:49 PM roycroft: i was just on ebay earlier looking at some vintage hifi gear
10:49 PM roycroft: apparently i made a really good investment when i got my mcintosh preamp and power amp about 15 years ago
10:50 PM roycroft: both are going for over 4x what i paid for them tnen
10:50 PM roycroft: then
10:50 PM roycroft: i guess the old, good stuff is getting scarce
11:04 PM Bleepshop: Yeah, Ive got an OLD analog White/Pink noise generator I've got squirelled away in storage. impossible to machine calculate a cancellation for. >:)
