12:21 AM memleak: bbl going to rebuild everything myself
01:27 AM Deejay: moin
02:47 AM memleak: updated rtai to 5.4.290
02:48 AM memleak: two easy conflicts is all
02:50 AM memleak: making all new debian packages, linuxcnc 2.9.4 rtai as well
03:03 AM memleak: brb
03:17 AM lcnc-relay: <meisterdippel@> moin
03:36 AM memleak: wow..
03:36 AM memleak: https://paste.debian.net/1350202/
03:39 AM memleak: these permission denied and No such file or directory errors are concerning...
03:39 AM memleak: i'm hoping i just need to run the dch git script
03:39 AM memleak: installing devscripts now
03:52 AM memleak: almost there.. built the deb, ran into errors installing
03:52 AM memleak: https://paste.debian.net/1350204/
04:17 AM memleak: ok i have all new debs now
04:19 AM memleak: under load on all cores compiling: https://imgur.com/a/v95NZms
04:19 AM memleak: no isolcpus
04:20 AM memleak: posting them later on
04:20 AM memleak: (the debs)
04:22 AM memleak: new patches: https://github.com/NTULINUX/RTAI/tree/master/ksrc/v5.4.290
04:22 AM memleak: off to bed, night all!
06:42 AM Deejay: hmm, wondered why linuxcnc does stop if probe-in gets toggled during normal program execution...
06:43 AM Deejay: mill was running, I put a small piece of wood aside on the mill to stop the chips from being distributed from everywhere
06:43 AM Deejay: that piece of wood fell on the flat side and hit the tool length sensor. this caused linuxcnc to stop :/
06:45 AM Deejay: have changed my hal-config, now probe-input is: probe-input & !spindle.on. so the probe-input will only get high if the spindle is not running
06:45 AM Deejay: now I can toggle the tool length switch while the mill is running without stopping :)
06:46 AM Deejay: (stopping happened several times, i.e. when hitting the switch while collecting the chips with the vacuum cleaner etc)
06:47 AM Deejay: I like the flexibility of LinuxCNC :)
07:42 AM Deejay: anyone with an Intel N100 mainboard who experiences system freezes on reboot or shutdown occasionally?
07:43 AM Deejay: i have this problems, tried some kernel parameter but found no solution yet :/
07:47 AM Deejay: i am running debian bookworm with the latest preempt-rt-kernel
07:51 AM JT-Cave: not on mine, it's been up and running for a couple of weeks
07:52 AM JT-Cave: using the grub customizer my kernel parameters are quiet isolcpus=3 idle=poll
08:08 AM Deejay: hmm okay
08:09 AM Deejay: running is mine too, the system freezes only sometimes when shutdown or rebooting
08:11 AM Deejay: i'm quite happy with the performance of the n100, its a really nice system for running my mill
08:54 AM lcnc-relay: <TheMightyFozz> I am thinking about getting a n100 to build a laser cutter. are they good enough for laser etching speeds?
08:55 AM bjorkintosh: what are the specs, TheMightyFozz?
08:55 AM bjorkintosh: and what do you plan on etching?
08:56 AM lcnc-relay: <zincboy_ca_on@> There are dedicated laser controller that work really well. I wouldn't bother using anything else after using one. There are a bunch of laser specific features that would be pain to replicate.
08:58 AM lcnc-relay: <TheMightyFozz> I want to build a 130w co2 laser. I already built a linuxCNC 8ftx4ft CNC router. I want to avoid propritory software. so my choices are GBRL or LinuxCNC
08:59 AM lcnc-relay: <TheMightyFozz> the machine will be 900x600. i feel its pointless going bigger due to the falloff of the laser.
09:02 AM lcnc-relay: <TheMightyFozz> I plan on etching slate, wood and maybe plastics.
09:06 AM lcnc-relay: <zincboy_ca_on@> Lightburn + the laser controller of your choice would be what I would go with. Engraving with linuxcnc would be tricky as you need a pwm output to modulate the laser power. Not sure how you would implement that other than a bunch of short moves and using a spare axis as the power output. I do think you would need a mesa board to hit the step rates and pwm speed required.
09:07 AM lcnc-relay: <TheMightyFozz> yeah. I am thinking GBRL might be the way forward for this project.
09:12 AM lcnc-relay: <TheMightyFozz> this looks cool! https://www.youtube.com/watch?v=mS1OmVB2Xpg&t=727s&ab_channel=ExplainingComputers
09:12 AM lcnc-relay: <TheMightyFozz> Radxa X4: An N100 Pi
09:30 AM -!- #linuxcnc mode set to +v by ChanServ
10:45 AM lcnc-relay: <huursabg@> Do flat bottom drills need a spot drill, because I've seen videos of them where they just go straight in without any pilot hole
10:46 AM -!- #linuxcnc mode set to +v by ChanServ
10:46 AM lcnc-relay: <huursabg@> And those were by the manufacturer themselves
10:58 AM bjorkintosh: huursabg while pilot holes are great, you can drill any size hole you want if you use the right feeds and speeds for the material in question.
10:58 AM bjorkintosh: I like pilot holes myself.
11:18 AM lcnc-relay: <roguish> huursabg@: I use flat end mills to drill occasionally, but not straight in. I use a helix feed, generally with a center pilot hole too.
11:32 AM -!- #linuxcnc mode set to +v by ChanServ
11:48 AM Tom_L: for a flat bottom drill a pilot doesn't make sense because the pilot is to guide the point of the drill and if the drill has no point, it's pointless
11:49 AM roycroft: i saw what you did there
11:49 AM Tom_L: :)
12:09 PM memleak: LMAO
12:13 PM memleak: how are these numbers? https://imgur.com/a/Zn0JWaN :)
12:13 PM memleak: under load and no load
12:17 PM lcnc-relay: <big_kevin420@> https://github.com/sarahiqown/Startup-Wizard/issues/159
12:17 PM lcnc-relay: <big_kevin420@> you guys think this is legit? lol
12:17 PM memleak: time to start qemu
12:31 PM Tom_L: big_kevin, check it out and let us know :)
01:01 PM memleak: andypugh_, got a PR for you: https://github.com/LinuxCNC/linuxcnc/pull/3340
01:02 PM memleak: wow a lot has happened since 5.4.258: 2925 files changed, 34840 insertions, 22958 deletions
01:15 PM memleak: whoever mostly fixed the ability to build linuxcnc debs without docs, thank you
01:16 PM memleak: 2 files changed, 4 insertions(+), 7 deletions(-) -- what it takes now to disable docs
01:16 PM memleak: before it was over 100 lines
01:49 PM JT-Shop: actually a flat bottom drill is common for wooden boat builders to use it's called a bare foot auger
01:50 PM JT-Shop: you do have to start the hole with a normal twist bit
02:27 PM lcnc-relay: <captainhindsight_.@> pointless drills are also called rods
02:33 PM lcnc-relay: <captainhindsight_.@> https://www.metalsdepot.com/tool-steel-products/a2-drill-rod?gQT=1
02:38 PM lcnc-relay: <captainhindsight_.@> https://radxa.com/products/x/x4/#techspec
02:44 PM lcnc-relay: <captainhindsight_.@> Intel N100 connected to rp2040 onboard via SPI, 4GB ddr5 version is only $65
02:44 PM lcnc-relay: <captainhindsight_.@> https://shop.allnetchina.cn/products/radxa-x4
02:47 PM lcnc-relay: <big_kevin420@> hmm not bad
02:49 PM lcnc-relay: <captainhindsight_.@> not too shabby
02:53 PM lcnc-relay: <captainhindsight_.@> https://dl.radxa.com/x/x4/radxa_x4_v1.11_schematic.pdf
02:55 PM lcnc-relay: <captainhindsight_.@> 12 years later there is a board for machinekit
02:56 PM mrec: hat is the advantage of the rp2040 again?
02:57 PM mrec: what*
02:57 PM mrec: it is wired up via USB...
02:58 PM lcnc-relay: <captainhindsight_.@> via SPI
02:59 PM mrec: it says usb 2.0
02:59 PM lcnc-relay: <big_kevin420@> external step gen
02:59 PM lcnc-relay: <captainhindsight_.@> see the schematic
02:59 PM mrec: I am looking at page 3
03:01 PM mrec: spi is open?
03:01 PM mrec: I only see it connected to the RP2040 but not connected to anything..
03:02 PM mrec: so it is connected via usb
03:02 PM mrec: U2_USB2N_6
03:02 PM mrec: U2_USB2P_6
03:03 PM lcnc-relay: <big_kevin420@> looks like uart also
03:03 PM lcnc-relay: <big_kevin420@> hmm so the 40pin header is to the pico
03:03 PM mrec: uart might be another channel
03:04 PM lcnc-relay: <captainhindsight_.@> poorly labeled schematic and block diagram 😦
03:05 PM lcnc-relay: <captainhindsight_.@> plus shared pins doesn't help
03:05 PM lcnc-relay: <big_kevin420@> pg 22 damn theres so many pins
03:05 PM lcnc-relay: <big_kevin420@> uart for sure goes to cpu
03:05 PM lcnc-relay: <big_kevin420@> usb goes somewhere usb like
03:06 PM lcnc-relay: <big_kevin420@> spi connected to the flash for the pico
03:07 PM lcnc-relay: <captainhindsight_.@> oh well
03:08 PM mrec: dreams destroyed?
03:08 PM lcnc-relay: <captainhindsight_.@> get out the blue jumper wire
03:08 PM lcnc-relay: <captainhindsight_.@> nah I'd spin my own board if I really needed it
03:09 PM lcnc-relay: <big_kevin420@> hmm then the spi on the cpu goes to another spi flash
03:09 PM lcnc-relay: <big_kevin420@> yeah man its more work, but you can just get what you want instead
03:10 PM lcnc-relay: <captainhindsight_.@> not the first x86/am64 board with a micro connected wrong
03:11 PM lcnc-relay: <captainhindsight_.@> plus I'm not that interested in the race to the bottom except when it hurts intel
03:11 PM lcnc-relay: <big_kevin420@> i wonder if they can do an x86 compute module
03:11 PM lcnc-relay: <captainhindsight_.@> or TI
03:14 PM lcnc-relay: <captainhindsight_.@> they currently only make ARM compute modules
03:17 PM lcnc-relay: <captainhindsight_.@> which cpu is in current Fanuc CNC controllers?
03:17 PM mrec: did you check radxa how far they are opensource?
03:19 PM memleak: https://github.com/NTULINUX/RTAI/releases/tag/v5.3.3
03:19 PM mrec: they have some interesting boards I might study
03:19 PM mrec: I care less about the SW more about the HW
03:19 PM memleak: New RTAI stable release, .debs are up!
03:23 PM lcnc-relay: <big_kevin420@> i think fanuc has some asic or something there
03:25 PM JT-Cave: bathroom vent fan is good for another 10-15 years
03:27 PM Tom_L: full of lint?
03:29 PM Tom_L: set up a new printer and found the wlan can't see it when connected to wifi on the same router
03:29 PM Tom_L: never ran across that before
03:30 PM Tom_L: may be a windows 10 thing for all i know
03:34 PM memleak: uploading linuxcnc debs in a hot second
03:35 PM JT-Woodshop is now known as C3-Shop
03:35 PM C3-Shop: motor making noise as well as clogged with lint so a drop or three of oil and it's nice an quiet
03:37 PM Tom_L: i could have put the printer on the wlan but would require adding a switch in that room which i wasn't up to doing today
03:54 PM lcnc-relay: <captainhindsight_.@> https://onelaboratories.us/abc/ LCNC RTAI debs, needs to be tested
03:55 PM lcnc-relay: <captainhindsight_.@> works here 🙂
03:55 PM Tom_L: i've been using it
03:55 PM lcnc-relay: <captainhindsight_.@> these are new for 5-10 minutes ago
03:55 PM Tom_L: oh
03:55 PM Tom_L: no i haven't tried those
03:55 PM lcnc-relay: <captainhindsight_.@> 2.9.4
03:55 PM Tom_L: did you dump the first set?
03:56 PM lcnc-relay: <captainhindsight_.@> the older ones are no longer posted there
03:56 PM Tom_L: using rtai 5.4.279?
03:56 PM lcnc-relay: <captainhindsight_.@> I don't recall
03:57 PM Tom_L: that's what the old ones was
03:57 PM lcnc-relay: <captainhindsight_.@> glad someone remembers
03:58 PM Tom_L: seems the ones you posted are 5.4.290
03:58 PM Tom_L: you need all those files?
03:58 PM Tom_L: or just the 2.9.4 deb?
04:01 PM lcnc-relay: <captainhindsight_.@> you need matching kernel and LCNC debs
04:02 PM lcnc-relay: <captainhindsight_.@> so all except for sources
04:02 PM lcnc-relay: <captainhindsight_.@> the forum post has the install instructions
04:03 PM lcnc-relay: <captainhindsight_.@> will likely post news there soon
04:03 PM lcnc-relay: <captainhindsight_.@> the dev is making eggs right now
04:06 PM Tom_L: does it matter what order to install the debs?
04:06 PM lcnc-relay: <captainhindsight_.@> testing that right now
04:06 PM lcnc-relay: <captainhindsight_.@> but someone keeps asking questions 🙂
04:07 PM Tom_L: got a link to the forum post?
04:14 PM lcnc-relay: <captainhindsight_.@> image first, then headers, then modules, then linuxcnc
04:17 PM Tom_L: ok
04:17 PM Tom_L: i grabbed em and made a note for later
04:18 PM lcnc-relay: <captainhindsight_.@> somthins up
04:18 PM lcnc-relay: <captainhindsight_.@> needs more testing
04:18 PM Tom_L: i'm guessing i can purge the old then install these
04:19 PM Tom_L: ok i'll wait
04:19 PM lcnc-relay: <captainhindsight_.@> hold on for now
04:19 PM lcnc-relay: <captainhindsight_.@> why we test on more than one system
04:34 PM memleak: Tom_L, that's how updates work, the numbers usually go up as they update.
04:35 PM memleak: the old ones were removed because nobody cares about old cruft.
04:36 PM Tom_L: they do if the bleeding edge is bleeding too much
04:36 PM Tom_L: i have em anyway
04:36 PM roycroft: the history of development of a software package can be interesting and sometimes useful
04:36 PM roycroft: i don't purge things because they're old
04:36 PM roycroft: i archive them
04:36 PM memleak: anything 5.4 is ancient anyway,m and roycroft that's good for you.
04:37 PM memleak: i dont want people asking me questions about code i no longer support
04:37 PM roycroft: it's good for a lot of people, and good practice
04:37 PM roycroft: so don't support it
04:37 PM memleak: i wont, gladly.
04:37 PM roycroft: tell people you won't support anything prior to what you decide is your threshold
04:38 PM roycroft: but it's a disservice to disappear the old stuff completely
04:38 PM roycroft: i'm glad i know you do that - i'll avoid any of your code that i might otherwise fine useful
04:38 PM * memleak laughs my ass off at anyone who thinks a 5.4 kernel is bleeding edge
04:38 PM * roycroft doesn't recall anyone even alluding to 5.4 being bleeding edge
04:39 PM memleak: oh, Tom_L implied it earlier.
04:39 PM Tom_L: get your pissin done and measured and get on with life
04:39 PM roycroft: you might want to acquire some critical reading skills :)
04:40 PM * roycroft agrees, and heads back out to continue tidying up the shop
04:40 PM memleak: lol
04:46 PM lcnc-relay: <captainhindsight_.@> ok i borked the install here, my brain is almost working again, I forgot to uninstall the old rt lcnc install
04:47 PM lcnc-relay: <captainhindsight_.@> before installing the RTAI stuff
05:03 PM lcnc-relay: <captainhindsight_.@> Tom https://forum.linuxcnc.org/9-installing-linuxcnc/53163-new-and-working-rtai-debs-for-2-9?start=0
05:05 PM Tom_L: debs are ok then, just forgot to purge?
05:06 PM lcnc-relay: <captainhindsight_.@> likely, but reinstalling and testing now
05:06 PM Tom_L: ok
05:07 PM lcnc-relay: <captainhindsight_.@> started some new pain meds last month, they also kickstarted my brain, felt like i was in a cloud the past couple of years on cancer meds
05:08 PM lcnc-relay: <captainhindsight_.@> they have changed my life
05:08 PM memleak: i just dont have the manpower to support RTAI that isn't the latest, i don't work on RTAI full-time.
05:09 PM memleak: i've actually been hacking away at preempt_rt for the last month or so
05:09 PM memleak: and i'll be busy supporting my gentoo images, one with preempt_rt and the other with rtai
05:11 PM memleak: there aren't any gentoo users here that i know of so i'll be offering gentoo support mostly as it's a whole new world compared to debian
05:13 PM memleak: the amount of problems on debian i've encountered over the the past few days are the same i'd have on gentoo over the course of a year
05:14 PM memleak: dpkg didn't even want to remove the kernel
05:14 PM memleak: subprocess returned error code 1 or something
05:15 PM memleak: and then the package manager is complaining about missing raspberry pi firwmare on an amd64 system, like wtf?
05:15 PM Tom_L: it wasn't wrong
05:15 PM Tom_L: it probably was missing
05:16 PM memleak: i want it missing, and i want to remove my kernel. debian says screw you.
05:16 PM memleak: i'm not going to git clone raspberry pi firmware in my /boot folder just so apt works
05:17 PM lcnc-relay: <captainhindsight_.@> debian knows what's best for us 🙂
05:17 PM Tom_L: not nearly as much as windows
05:17 PM memleak: that's like a bank saying they're not as bad as chase
05:18 PM memleak: "well hey, it's not hitler!"
05:32 PM lcnc-relay: <captainhindsight_.@> there will be a longer howto for RTAI
05:33 PM lcnc-relay: <captainhindsight_.@> LCNC has more dependencies
05:33 PM lcnc-relay: <captainhindsight_.@> so later this week for a working howto install RTAI
05:34 PM JT-Shop: lcnc has way too many dependencies
05:35 PM lcnc-relay: <captainhindsight_.@> I started from a Debian Net ISO vs the LCNC ISO
05:36 PM lcnc-relay: <captainhindsight_.@> the net ISO installed more stuff than the LCNC ISO, but different stuff
05:40 PM lcnc-relay: <captainhindsight_.@> the debs work
05:40 PM memleak: the linuxcnc repo needs to account for more dependencies
05:41 PM memleak: when installing bvia dpkg, there's like 20 that don't get installed with it
05:41 PM lcnc-relay: <captainhindsight_.@> image first, then headers, then modules, then linuxcnc
05:41 PM memleak: gtksourceview qsintilla or whatever it's called (qcsi or something)
05:42 PM lcnc-relay: <captainhindsight_.@> and a couple of extra steps if you install from a Debian ISO vs LCNC ISO
05:42 PM memleak: linuxcnc needs to account for these mostly: python3-opengl tcl-dev tk-dev libmodbus-dev bwidget blt mesa-utils libusb-1.0-0-dev libgtk-3-dev libgtk2.0-dev intltool libreadline-dev python3-tk libglu1-mesa-dev libxmu-dev python3-gi-cairo iptables python3-numpy python3-gi-cairo python3-opengl python3-configobj libgtksourceview-4-dev tclreadline python3-pyqt5.qsci python3-pyqt5.qtsvg python3-pyqt5.qtopengl python3-opencv python3-espeak python3-dbus.mainloop.
05:42 PM memleak: pyqt5 python3-pyqt5.qtwebengine python3-pyqt5.qtwebkit espeak-ng pyqt5-dev-tools gstreamer1.0-tools espeak python3-poppler-qt5
05:43 PM Tom_L: paste.debian.net works great for that
06:35 PM memleak: does dpkg not install package deps?
06:36 PM memleak: dpkg knows what's missing but leaves it up to me to install, wondering if this is by design
06:41 PM lcnc-relay: <grandixximo@> it is
06:42 PM lcnc-relay: <grandixximo@> apt installs them for you, i think using dpkg in the background, but I could be wrong about that
06:43 PM memleak: how do you install a .deb without calling dpkg directly?
06:43 PM memleak: i want the debs but i only have a file
06:44 PM roycroft: aptitude is essentially a high-level front end to dpkg
06:44 PM lcnc-relay: <grandixximo@> I like to use gdebi
06:44 PM lcnc-relay: <grandixximo@> it's graphical makes it easier
06:45 PM roycroft: i install .deb archives dirctly with dkpg
06:45 PM lcnc-relay: <grandixximo@> open with gdebi, and it installs it
06:45 PM roycroft: dpkg, rather
06:45 PM roycroft: it doesn't get much easier than "dpkg install file.deb"
06:46 PM lcnc-relay: <grandixximo@> it won't install dependency
06:46 PM lcnc-relay: <grandixximo@> sudo apt install ./package-name.deb
06:46 PM lcnc-relay: <grandixximo@> this will
06:46 PM roycroft: i've never heard of gdebi, so i can't say anything about that
06:46 PM roycroft: oh, it's a gnome gui tool
06:47 PM roycroft: i don't have any linux machines that have guis installed, so that's probably why i've not heard of it
06:47 PM lcnc-relay: <grandixximo@> https://simple.wikipedia.org/wiki/GDebi
06:47 PM roycroft: it's nowher near my radar
06:47 PM roycroft: but yes, apt install packagename will generally (mostly) install dependencies
06:47 PM lcnc-relay: <grandixximo@> sudo apt --fix-broken install
06:48 PM lcnc-relay: <grandixximo@> you can use that to install the missing dependencies
06:48 PM lcnc-relay: <grandixximo@> even if you installed with dpkg i think
06:48 PM roycroft: usually when i install a stand-alone .deb it either has all its dependencies embedded in the .deb file, or it has documentation listing the prerequisites
06:49 PM lcnc-relay: <grandixximo@> sudo apt-get install -f
06:49 PM lcnc-relay: <grandixximo@> or this
06:49 PM roycroft: it's not often that i have to install a stand-alone .deb file, though
06:49 PM memleak: OH!!!
06:50 PM memleak: you can apt install ./file.deb ?
06:50 PM memleak: and that'll bring in the dependencies? SUH-WEET
06:54 PM lcnc-relay: <grandixximo@> yes but the dependency cannot be other .deb that you have in the same folder, at that point it maybe better to do
06:54 PM lcnc-relay: sudo apt install ./*.deb
06:55 PM memleak: ok, yeah with dpkg i use a for loop.. for i in *.deb ; do sudo dpkg "${i}" ; done
06:56 PM memleak: dpkg doesn't like multiple files
06:56 PM memleak: thank you!
06:56 PM memleak: i don't know all the debian tricks
06:56 PM lcnc-relay: <grandixximo@> sudo apt install ./*.deb
06:56 PM lcnc-relay: this is easier it will organize and install in correct order, and take care of packages that are to eb downloaded
06:56 PM lcnc-relay: <grandixximo@> * be
06:59 PM memleak: awesome!
07:11 PM lcnc-relay: <captainhindsight_.@> sudo apt --fix-broken install worked for me
07:12 PM lcnc-relay: <captainhindsight_.@> what a waste of time
07:25 PM memleak: i don't think back in 07/08 debian allowed installing debs through apt
07:26 PM memleak: maybe i just never tried it..
07:45 PM Tom_L: i've used both dpkg -i and gdebi
07:45 PM memleak: yeah dpkg leaves the deps up to the user
07:45 PM memleak: got it all figured out now though, just use apt to install .deb
07:48 PM lcnc-relay: <ccatlett1984@> that's amazing (apt install .deb), just adjusted my 7c80 / pi5 install doc to use that vs dpkg
07:48 PM memleak: heh
07:57 PM lcnc-relay: <grandixximo@> I was looking at Tom's g-code in the flex chat, https://paste.debian.net/1350037/ i see he is using @ and ^ as axis names, is this documented?
07:57 PM lcnc-relay: G0 @[0 + #2043] ^#2039 Z#2050
08:42 PM lcnc-relay: <skunkworks8841@> https://linuxcnc.org/docs/stable/html/gcode/overview.html
08:42 PM lcnc-relay: <skunkworks8841@> Good start
08:44 PM lcnc-relay: <skunkworks8841@> Although I think that is polar coordinates

09:28 PM Tom_L: yes
09:28 PM Tom_L: the @ establishes a radius for an arc and ^ is the angle
09:29 PM Tom_L: once you have the radius established all you need for the next iteration is the ^ angle increment be it G90 or G91
09:29 PM Tom_L: mode
09:30 PM Tom_L: something that isn't documented that well
09:31 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/hole_pattern.mkv
09:31 PM Tom_L: is the result of that code
09:37 PM Tom_L: it is also in the flexgui examples
10:19 PM faheus1 is now known as faheus
10:21 PM Unterhaus_ is now known as Unterhausen
10:48 PM lcnc-relay: <grandixximo@> Thank you 👍
10:58 PM NetPipe: https://www.youtube.com/watch?v=vVakcj4ilS8 easy check valves
11:07 PM lcnc-relay: <grandixximo@> If what you are running trough the pipes is a decently clean fluid, and you don't care about flow, it's a nice quick fix. I can see too many ways it can fail with any kind of impurity. And i believe the flow will be substantially reduced.
