12:23 AM sensille: is it only me or does setting up the workpiece take a long time?
12:29 AM LotsaRastaPasta: it can
01:21 AM Loetmichel: mornin'
01:24 AM LotsaRastaPasta is now known as CaptHindsight
01:51 AM Loetmichel: [out of coffee grinds error] *sh**... How am i supposed to get awake now?
01:52 AM sensille: .oO ( ... sports? ... )
01:54 AM Loetmichel: sensille: i'll take the Churchill approach: "NO SPORTS!"
01:56 AM sensille: too bad. then ... cold shower?
02:00 AM Loetmichel: or send one of the coworkers down to the grocery shop ;)
02:21 AM rmu|w: churchill did play polo (if this qualifies as a sport)
03:35 AM Loetmichel: *sizzle* THAT will be a blister. Note to self: on 40W co2 lasers: Not only not look into the beam, also dont reach into it! :-(
04:25 AM XXCoder: Thorhian: cool! on mesa and rpi4
04:25 AM XXCoder: Loetmichel: do not reach into beam with your remaining hand
04:26 AM XXCoder: jymmmm: yeah but then need power for range and that doesnt have it
04:57 AM JT-Cave: morning
04:57 AM XXCoder: hey jt
05:06 AM JT-Cave: damn rain
05:07 AM XXCoder: rain damn you too ;)
05:08 AM XXCoder: random rain here which is good. more rain, shorter summer.
05:11 AM Loetmichel: XXCoder: only 40W
05:12 AM Loetmichel: no hand cutting
05:12 AM XXCoder: ya had to play out from remaining eye thing
05:12 AM Loetmichel: esoecially not in the unfocussed beam
05:12 AM Loetmichel: just have a 3mm diametaer back dot on my hand now
06:24 AM Tom_L: morning
06:35 AM JT-Cave: morning
06:37 AM Tom_L: JT-Cave, have you tried static ip on the rpi yet?
06:37 AM JT-Cave: yes, all my rpi's have a static ip
06:37 AM Tom_L: how do you go about setting that up?
06:38 AM Tom_L: i tried thru the config but i think it misses a step or three
06:38 AM JT-Cave: right click on the wifi icon in the top right
06:38 AM Tom_L: i got the ip set but think i'm missing something
06:38 AM Tom_L: yes i did that
06:39 AM JT-Cave: wireless and wired network settings
06:39 AM Tom_L: right
06:39 AM Tom_L: i got to the wired eth0
06:39 AM JT-Cave: configure eth0
06:40 AM JT-Cave: and type in the IPv4 address
06:40 AM Tom_L: i did
06:40 AM JT-Cave: click apply
06:40 AM JT-Cave: and reboot
06:40 AM Tom_L: no subnet mask needed?
06:40 AM JT-Cave: no
06:40 AM Tom_L: i usually add that on a normal pc
06:40 AM JT-Cave: let it automatically apply them
06:41 AM Tom_L: i did all that and it won't connect to the mesa board
06:41 AM Tom_L: i verified the mesa card with a pc
06:41 AM JT-Cave: what address did you use and what jumper settings do you have
06:41 AM Tom_L: 10.10.10.1 for the pi
06:41 AM Tom_L: and the mesa card is set for 10.10.10.10
06:41 AM JT-Cave: I always use 10.10.10.11
06:42 AM JT-Cave: I think .1 is magic or something
06:42 AM Tom_L: heh i've always used ^^
06:42 AM JT-Cave: can you ping the mesa card?
06:42 AM Tom_L: i'll try it again when i get back
06:42 AM JT-Cave: ok
06:43 AM Tom_L: i didn't try to ping it but i did have it hooked up to another pc and verified it
06:43 AM Tom_L: using those settings
06:43 AM p0g0: Put a hub/switch in the network, add another interface on the same net and run wireshark if you really need to see all the traffic.
06:43 AM JT-Cave: I use angry ip
06:44 AM Tom_L: i've used both before
06:44 AM p0g0: any packet sniffer
06:44 AM Tom_L: i bet angry ip would install on the pi
06:44 AM JT-Cave: yep
06:45 AM Tom_L: probably turn off wifi to avoid getting all that traffic
06:45 AM Tom_L: it would be on a different net mask anyway
06:45 AM p0g0: is the wifi bridged? if not, it should be a different net anyway
06:46 AM Tom_L: JT-Cave, still raining?
06:47 AM Tom_L: we got lots of lightening last night
06:51 AM CaptHindsight is now known as MyBrainHurts
06:58 AM Tom_L: just started pouring
06:58 AM JT-Cave: just started to rain again
06:58 AM * Tom_L gives JT-Cave a few more buckets full
06:58 AM * JT-Cave is growing webbed feet
06:58 AM p0g0: soon gills?
07:00 AM * JT-Cave is above the high water mark
07:13 AM jymmmm: good morning
07:14 AM jymmmm: JT-Cave is now known as JT-Pond, webbed feet and all ;)
08:44 AM p0g0: JT-Cave, Deutche Welle (dw.com) has a cautionary tale of Pablo Escobar's fugitive hippos. A bit more global warming and rain, and you too might have a 3 ton riparian beast wading nearby.
09:03 AM JT-Cave: yummy hippo sandwiches
09:27 AM Loetmichel: JT-Cave_ careful, angry hippos are not to trifle with. they kill (to my knowledge) more people every year than aligators
09:47 AM skunkworks: isn't that what ate james parents?
09:52 AM p0g0: Hippos kinda hate humans. I recall being at the Cincinatti zoo decades back and seeing a woman stray too near the Hippo pen where she got nailed from 10 meters off by a firehose scale stream of hippo urine, a memorable sight for sure.
09:56 AM roycroft: if somebody captured you, dragged you to cincinatti, and locked you up in a pen, you would probably be pissed off at them too
09:56 AM roycroft: don't blame the hippo
09:56 AM roycroft: :)
09:57 AM p0g0: I didn't, and that was the last time I have been to a zoo, they depress the heck out of me in fact.
11:21 AM jymmmm: WOW, this guy is bad, like scary bad... https://www.youtube.com/watch?v=6qdLBcOoSPI
11:21 AM ziper: is 17 SCFM @ 19 inches of Hg enough for a 5x10 router table?
12:11 PM dirty_d: I just made a burger by grinding sirloin steak, garlic, butter, and Korean red pepper flakes together.
12:11 PM dirty_d: god damn that was good, i need to do more weird shit more often
12:11 PM MyBrainHurts: ruin a steak?
12:12 PM dirty_d: nah, I still have enough left to grill
12:12 PM dirty_d: burgers are way better when they're not made from lips and ass
12:13 PM HexaCube: hey folks
12:17 PM HexaCube: I know I asked in here already but it's been a few months, so sorry about reasking stuff... What sort of option would you guys recommend, when I want a CNC controller without spending more than.... around 150 EUR?
12:22 PM MyBrainHurts: cheap PC, OraangePi
12:22 PM MyBrainHurts: https://cnc32.ru/orangecnc/
12:23 PM MyBrainHurts: suffer with GRBL and *duino
12:26 PM MyBrainHurts: HexaCube: all depends on what you want to do and settle for
12:30 PM HexaCube: though question, really. I'd like to use F360 as a CAM, and be able to control pretty much anything if possible, right from linuxcnc (or any other software for that matter). I'd also be interested in using encoders for closed loop operation
12:30 PM HexaCube: I remember reading about MESA cards but I think I never really found out which board I'd need (want?) for a basic cnc setup
12:31 PM HexaCube: then again those are fairly expensive, right?
12:37 PM Loetmichel: hmm, i am getting rusty. or the cars getting more complicated... just took me 1,5h to get the %/$%&/ driver side window back in its drive clamps... most of the itme was spent to get the covers off, all the airbags and motors out and that /&%&/%&///%/&%&/&%&/ tar paper glued into the door to dampen sounds out and back in. :-(
12:45 PM dirty_d: HexaCube, an rpi also works, but it's not really fast enough to enjoyably use F360 over RDP t oanother PC
12:47 PM dirty_d: HexaCube, the mesa card I'm using with my rpi was $115
12:48 PM dirty_d: The ideal situation is to have another PC in the shop to use F360 or whatever on
12:48 PM dirty_d: or at least in the same building
12:48 PM dirty_d: or house
12:49 PM HexaCube: Oh yeah I didn't intend to run F360 on the controller (PC) or anything, I wasn't sure if I need to make sure it's compatible
12:50 PM HexaCube: like... g-code flavor or postprocessing etc
12:50 PM dirty_d: F360 does have a postprocessor for linuxcnc
12:52 PM dirty_d: this is the mesa card I used http://store.mesanet.com/index.php?route=product/product&product_id=311
01:03 PM unterhaus: mcdonalds is packed. Not risking getting sick for that. Maybe the local steakhouse
01:07 PM Tom_L: but mcdonalds builds your immune system to fight off just about anything
01:11 PM Loetmichel: Tom_L: at least their food is immune to decay :)
01:17 PM unterhaus: have you ever seen the pictures of walmart ice cream left out for days?
01:18 PM Loetmichel: mope
01:18 PM Loetmichel: nope
01:19 PM unterhaus: "ice cream sandwiches don't melt" is a thing on google
01:19 PM unterhaus: walmart spokesman was forced to explain it
01:32 PM MyBrainHurts: odd flavor and consistency
01:37 PM Loetmichel: unterhaus: i think i know the ice cream in question. yes, thats more like marshmellows deep froze
01:37 PM Loetmichel: those things indeed dont melt
01:38 PM dirty_d: Whaaaaat, dude made his own steel https://www.youtube.com/watch?v=fuToSTnZTTY
01:39 PM FinboySlick: Oooh, Bob's a pretty amazing guy.
01:44 PM dirty_d: I've seen a lot of blacksmithing stuff on youtube, but I've never seen anyone try to make their own steel
01:44 PM MyBrainHurts: FinboySlick: https://i.imgur.com/x1AIXTb.jpg road in Quebec, is this common?
01:44 PM dirty_d: seems pretty simple from what he did
01:45 PM FinboySlick: MyBrainHurts: In Montreal, the paved ones are worse.
01:47 PM MyBrainHurts: now I have to drive there
01:48 PM FinboySlick: dirty_d: Bob Kramer is probably one of the most famous knife makers in tthe world. Started just shy of homeless and decided to master the craft.
01:51 PM dirty_d: whoa
01:53 PM norias: that steel making process seemed fairly straight forward
01:53 PM norias: a little bit of a let down
01:54 PM norias: is he using powdered metal inputs?
01:54 PM norias: (feedstock)
01:55 PM dirty_d: yea it was just powdered pure iron, manganese, and carbon
01:55 PM norias: awe, baby rolling mill
01:55 PM norias: so wild to see one so small and simple
01:57 PM dirty_d: I wonder if you can make maraging steel like that
01:57 PM Loetmichel: i like how he just "freehands" it on the belt sander and grinding wheels and voila: perfect cut!
01:58 PM dirty_d: maybe pipe some argon in through that firebrick
01:59 PM dirty_d: so there's no oxidation
02:04 PM MyBrainHurts: why not start with off the shelf steel plate?
02:04 PM MyBrainHurts: for arts sake?
02:09 PM Loetmichel: MyBrainHurts: because he can!
02:09 PM Loetmichel: also maybe there is noone making the kind of steel he wants
02:09 PM Loetmichel: and you wont get a steel mill to make you 10kg portions ;)
02:10 PM Loetmichel: of your desired alloy
02:10 PM JT-Shop: wow a 36" bar and ripping chain adds quite a bit of weight to the front of the MS391
02:10 PM Loetmichel: for such small batches it can be useful to buy powedered metals and mix yourself
02:43 PM SpeedEvil: I have wondered about that.
02:44 PM SpeedEvil: Also I've idly wondered about the best bronze AlO or diamond impregnated knife you could make.
03:00 PM MyBrainHurts: I installed some plating tanks at a place that diamond plated steel
03:01 PM MyBrainHurts: the scrap knife blades used to cut you pretty easily
03:01 PM MyBrainHurts: was like handling extra sharp razor blades
03:53 PM andypugh: I know you told me not to, but, new toy in the middle: https://photos.app.goo.gl/epSYKXaxAmFiVBPB7
03:54 PM XXCoder: few that could be counted as "middle" lol
03:54 PM XXCoder: i guess its press?
03:55 PM XXCoder: or small probably grinder thing on toolcart?
03:55 PM Tom_L: andypugh, on the red toolbox?
03:55 PM andypugh: Yes, the one on top of the red toolbox.
03:56 PM Tom_L: what is it?
03:56 PM Tom_L: some type of lathe?
03:56 PM XXCoder: looks like tool grinder
03:56 PM sync: a tool grinder
03:56 PM XXCoder: to add relief, etc
03:56 PM XXCoder: yup
03:56 PM XXCoder: work has larger and more expensive version. it can be super handy!
03:57 PM sync: I still need to get my cnc tool grinder running
03:58 PM XXCoder: for example if you use drill so deep it reaches shaft, you could use that to lower radius of shift, so it can keep going deeper ( in least till it hits toolholder!)
04:00 PM andypugh: Yes. And it can sharpen drills. Or set accurate angles on lathe tools. that sort of thing.
04:02 PM XXCoder: andy you can make really nice stylus points with it!
04:02 PM Deejay: gn8
04:02 PM XXCoder: all you need is some lathe work to make very nice body for the point
04:03 PM XXCoder: i used broken carbide endmill to make one, its very strong
04:03 PM XXCoder: can mark anything basically
04:39 PM MyBrainHurts is now known as SaidItAgainbefor
04:45 PM Thorhian: Wow
04:46 PM Thorhian: I'm now using my RPi4 with weechat to talk on here while I configure it lol
04:46 PM XXCoder: lol
04:46 PM XXCoder: hows your project so far
04:47 PM Thorhian: I've been troubleshooting the pi. It wouldn't display on my monitor until I plugged it into my tv and then plugged it back into my monitor.
04:48 PM Thorhian: Now that I'm on, I've been configuring Rasbian to be something to my liking before beginning to install the preempt-rt kernel. Installed i3 and various things. Not a fan of openbox.
04:50 PM Thorhian: Had to grab Vim and Doom Emacs as well.
04:50 PM XXCoder: what about xfce
04:50 PM XXCoder: very effective and fairly lean
04:50 PM Thorhian: *shrug* It's okay, I prefer tiling WMs.
04:51 PM XXCoder: cool :)
04:56 PM Thorhian: It's kind of cool to use this and discord on the pi. Fairly usable, but not nearly as responsive as my desktop or laptop. Maybe it has to do with running everything off an SD card?
04:58 PM XXCoder: yeah read/write isnt as good
05:00 PM skunkworks: I have an older toshiba tv that the pi didn't seem to display to..
05:00 PM skunkworks: but that was a long time ago - when I was first setting the PI up
05:02 PM skunkworks: I honestly just use whatever is installed.. initally gnome on ubuntu then xfce on the debian builds.
05:02 PM skunkworks: I have tried others - but they all work mostly
05:03 PM skunkworks: I am not picky
05:03 PM skunkworks: peck-rigid tapped 8 holes today. No issues.
05:03 PM skunkworks: 5/8"
05:03 PM XXCoder: with rpi4 controlled cnc?
05:03 PM Tom_L: peck-rigid?
05:03 PM Tom_L: is that a thing?
05:03 PM skunkworks: No - this was the K&t
05:04 PM Tom_L: backed out and re'entry
05:04 PM skunkworks: Tom_L: sure
05:04 PM XXCoder: yeah never heard of peck cycle tap
05:04 PM Tom_L: sounds fun
05:04 PM skunkworks: it was a conventional hand tap - didn't want to push it.
05:04 PM XXCoder: spindle would be very precise indeed heh
05:04 PM skunkworks: we do things slow and easy ;)
05:04 PM XXCoder: why not use thread mill?
05:05 PM skunkworks: don't have any
05:05 PM XXCoder: though if thin enough it wont work
05:06 PM Thorhian: If I have to use it a lot, especially for my cnc machine, I'd rather have something that works with me than against me.
05:07 PM skunkworks: this was in 1/2" steel - I think
05:07 PM Tom_L: skunkworks, you should get some, they're fun
05:07 PM skunkworks: nothing too taxing
05:07 PM skunkworks: Tom_L: we made one - it worked ok.
05:08 PM Tom_L: http://onlinecarbide.com/sipithmi.html
05:08 PM Tom_L: i got a handfull of those
05:08 PM Tom_L: mostly because the sherline spindle won't do rigid tapping very well
05:09 PM Tom_L: but it can do a 3/4-11 easy
05:09 PM Tom_L: err whatever the pitch was
05:09 PM skunkworks: Tom_L: cool - not too shocking ;)
05:10 PM Tom_L: jt n i both made macros to generate the code
05:10 PM skunkworks: Tom_L: how is your PI4 coming?
05:11 PM Tom_L: good
05:11 PM Tom_L: i've tested both spi and eth on it with mesa cards
05:12 PM Tom_L: going thru the config again to 'optimize?' it
05:13 PM XXCoder: make backups in case you optimize it to nothing
05:13 PM skunkworks: heh - cool
05:13 PM Tom_L: meh, i have the original img
05:13 PM XXCoder: :)
05:13 PM Tom_L: and a spare 64gb sd
05:14 PM Tom_L: haven't touched the sd that came with it yet
05:14 PM skunkworks: it came with and sd?
05:14 PM Tom_L: i got a kit
05:14 PM skunkworks: what kit did you buy?
05:14 PM skunkworks: mine came with a power supply and heat sinks.. I think that was it.
05:14 PM Tom_L: one XXCoder recomended
05:14 PM Tom_L: https://www.amazon.com/gp/product/B07XTQL6YZ/
05:15 PM Tom_L: then i got that fancy heatsink cover for it
05:15 PM XXCoder: its quite decent kit yeah. fan is only ponental issue though it works
05:15 PM Tom_L: i really like that
05:15 PM Tom_L: never unboxed the case it came with :)
05:16 PM Tom_L: only issue with it is the tight fit on the IO header for a idc plug
05:16 PM Tom_L: i had to butcher one to make it fit
05:16 PM Thorhian: I got the metal heatsink case that was linked in this chat at this point.
05:17 PM Tom_L: https://www.amazon.com/Metal-Raspberry-Heatsink-Thermal-Adhesive/dp/B07VMD25SK
05:17 PM Thorhian: That's the one lol
05:17 PM Tom_L: they could have widened the slot a tiny bit more
05:17 PM Thorhian: Use your mill ;)
05:18 PM Tom_L: it's already stuck on the board
05:19 PM Thorhian: Unsrew it?
05:19 PM Tom_L: i probably could
05:19 PM Tom_L: eventually i'll just get another one i'm sure
05:20 PM Tom_L: skunkworks, i get an error cpu0 not supported on boot. is that normal?
05:20 PM Thorhian: Are there good wiring diagrams/instructions for the 7C81?
05:20 PM Tom_L: his manual
05:20 PM Tom_L: i've never looked at one
05:20 PM skunkworks: Tom_L: yes - it is something about KVM
05:21 PM skunkworks: I doubt you will be running any virtual machines on the pi...
05:21 PM Tom_L: wonder if webpack will fit :D
05:22 PM skunkworks: for the fpga stuff?
05:22 PM Tom_L: that would take an eternity to synthesize a bit file
05:22 PM Tom_L: yes
05:22 PM Tom_L: i re'did mine for spi last night
05:23 PM skunkworks: Is this going to run your home made mill?
05:24 PM Tom_L: you never know. if it does it will be ethernet
05:24 PM Tom_L: since the cabinet has no more room for stuff and spi needs a short cable
05:25 PM Tom_L: that would be a simple drop in replacement from the 7i90 to 7i80
05:25 PM skunkworks: yah - plus putting the pi in the electrical box - you lose wifi and all the usb connections/
05:26 PM Tom_L: i've got a roll of auto trim adhesive that comes in quite handy for that
05:26 PM Tom_L: stick it to the door :(
05:26 PM Tom_L: )
05:26 PM skunkworks: mine currently just sits on top of the monitor arm..
05:26 PM skunkworks: classy
05:27 PM Tom_L: and i'd have to get an adapter or a hdmi monitor out there
05:27 PM Thorhian: I'm going to use SPI, and I'll probably do networking via ethernet. Way more reliable.
05:27 PM Tom_L: Thorhian, i posted the pinout here earlier
05:27 PM Thorhian: Oh, I'll look back.
05:28 PM Tom_L: err in the devel channel
05:28 PM skunkworks: https://www.youtube.com/watch?v=KpuFIqfQ1CE&feature=youtu.be
05:28 PM Thorhian: Ah... Yeah I don't have the link ATM. Maybe when I get back to my desktop.
05:28 PM Tom_L: SPI pinout
05:28 PM Tom_L: 7i90 Rpi4
05:28 PM Tom_L: 11 ----- 23 spi-clk
05:28 PM Tom_L: 13 ----- 19 spi-mosi
05:28 PM Tom_L: 15 ----- 21 spi-miso
05:28 PM Tom_L: 17 ----- 24 spi-ce0
05:28 PM Tom_L: 10 ----- GND
05:29 PM Tom_L: oh you just need a ribbon for the board you got i think
05:29 PM Tom_L: ask pcw_mesa about that
05:29 PM Tom_L: yours piggybacks on the pi right?
05:30 PM Tom_L: mine was a bit different
05:30 PM Thorhian: I was thinking about just using the SPI pins, and yeah, it has the same pins as the Pi.
05:30 PM Thorhian: I really want to power the Pi with it's own PSU through USBC, the 5V pinout doesn't have protection.
05:33 PM _unreal_: thorhian My PI/tinkerboard box and YES I have the mold. https://photos.google.com/share/AF1QipNjUL9VJW4BIh58ZOHM6jOWS10l43lfzL_nr7FMD-YXm_o6hG63BfTN2Rv6ch6C_Q?key=OVV0UTBXUmF0NXNSR2NKVzdoaFhxQzVTbDI5V3JB
05:34 PM Thorhian: That's cool unreal
05:38 PM _unreal_: VERY customization friendly
05:40 PM skunkworks: http://electronicsam.com/images/greenmachine/IMG_20200119_160436.jpg
05:40 PM dirty_d: Thorhian, I went with the ethernet card with my pi, and use a usb3 hub/ethernet adapter for networking
05:40 PM Thorhian: Noice dirty_d.
05:41 PM dirty_d: I like the idea of the mesa card being in the control box and being able to use any computer with it in case the pi doesn't work out
05:41 PM dirty_d: it is pretty slow, but good enough for linuxcnc
05:42 PM dirty_d: I'm tempted to try archlinux arm because they have builds for the specific cpu ion the pi4, maybe it's a little faster
05:43 PM dirty_d: raspbian is compiled to run on pi1 - pi4 I believe
05:53 PM Thorhian: Hmm, I want an integrated solution, and it's a pain in the but to find decent x86 hardware for linuxCNC. Singleboard ARM computers seem to be a fairly good solution. Besides, there are other singleboard computers that are similar enough to the pi that are more powerful and can handle the needed SPI communication.
05:54 PM Thorhian: Well, time to reboot the pi lol. BRB.
05:57 PM Thorhian: And I'm back, thankfully that worked.
05:58 PM Thorhian: uname -a
05:58 PM Thorhian: RIP
06:01 PM dirty_d: sweet
06:05 PM Thorhian: But yeah, I've seen SBC's with similar pinouts as the pi's with beefier although less supported hardware in terms of drivers with obnoxious "Rock Chips", even with NVME ports and sometimes mini PCIe.
06:06 PM andypugh: Thorhian: What makes you thnk it’s hard to find x86? As far as I know almost all of them work fine.
06:06 PM dirty_d: I may end up just using a PC
06:07 PM dirty_d: I built a ryzen 3 3200G box for my dad a couple months ago, tried linuxcnc on it for future reference, worked great
06:07 PM dirty_d: It would be nice to be able to use F360 from where I'm running linuxcnc
06:07 PM dirty_d: over RDP to another PC running windows
06:07 PM Thorhian: You know, I wonder how well the Nvidia Jetson Nano fairs. Also andy, I've heard multiple times that UEFI's aren't supported for preempt-rt, and my x570 board doesn't have explicit non-uefi mode compatibility.
06:09 PM Tom_L: what is Openbox?
06:10 PM Thorhian: A window manager Tom_L
06:12 PM rmu|w: Thorhian: booting from UEFI works just fine
06:13 PM Thorhian: Really rmu|w ? I've heard multiple comments telling that UEFI was a no go for the real time kernel.
06:17 PM MacGalempsy: andypugh can you help me figure out a problem I am having in fusion360?
06:17 PM andypugh: Maybe
06:17 PM MacGalempsy: trying to get text on a complex angled face
06:18 PM andypugh: Hmm, I probably can’t help
06:18 PM dirty_d: MacGalempsy, you mean across multiple non coplanar faces?
06:18 PM MacGalempsy: two 20 side polygons are lofted to make a face, but I cannot get a single letter to sit on each face
06:19 PM MacGalempsy: one of the youtube videos shows it working, but on an older version
06:19 PM rmu|w: Thorhian: i have a system running with UEFI only system, and it even has secure boot enabled
06:20 PM rmu|w: Thorhian: why should UEFI be a problem?
06:21 PM dirty_d: MacGalempsy, you can't start a sketch on each face and add the text?
06:21 PM MacGalempsy: when I try that, the letter goes down on the base. I cannot seem to make a parallel sketch
06:21 PM dirty_d: you should just be able to select the face to create the sketch on
06:22 PM dirty_d: maybe I'm not visualizing what you actually have right
06:26 PM dirty_d: I'm picturing a 20 sided cylinder
06:26 PM andypugh: MacGalempsy: You should be able to share the model with us
06:26 PM dirty_d: so 22 faces in total
06:28 PM SaidItAgainbefor is now known as CaptHindsight
06:30 PM MacGalempsy: https://a360.co/3dNM5Y1
06:32 PM dirty_d: it looks like you lofted a circle to a polygon
06:33 PM dirty_d: so those faces aren't planes and you can't sketch on them
06:33 PM andypugh: I was just about to say the same
06:33 PM dirty_d: but you might be able to create a tangent plan on each face
06:33 PM dirty_d: seems like a lot of manual labor
06:34 PM andypugh: Might be better to loft a polycon to a polygon
06:34 PM dirty_d: if you create text on the tangent plane and make the thing solid, you can extrude or cut the letters into the face below
06:34 PM MacGalempsy: That is what I am trying to do
06:35 PM dirty_d: it looks like you have faces down lower too that are planes
06:35 PM dirty_d: but I can't really tell from the web viewer
06:36 PM MacGalempsy: it just took trying agian
06:36 PM MacGalempsy: thanks guys
06:36 PM MacGalempsy: I dont know why it is working now
06:37 PM pcw_mesa: UEFI is only a problem for RTAI AFAIK
06:37 PM dirty_d: MacGalempsy, maybe this time you clicked lower and started sketching on the face that is a plane
06:39 PM MacGalempsy: maybe. I am glad to make headway. These are some give aways to my biggest client
06:39 PM MacGalempsy: they wanted their names on them, so no one would steal them. lol
06:39 PM dirty_d: nice, haha
06:40 PM andypugh: I creared a plane from two edges, and that worked: https://a360.co/2ybrQEM
06:50 PM Thorhian: rmu|w: I only thought that because people talking in this IRC channel.
06:53 PM pcw_mesa: The 7C81 <--> RPI cable should be a very short (~2 inch) 40 pin flat cable
06:59 PM MacGalempsy: That looks so much better!
07:02 PM Thorhian: pcw_mesa: Do I need to wire all of the pins to the 7C81?
07:07 PM pcw_mesa: You dont have to but you do want all the grounds and power connections for signal integrity reasons
07:09 PM Tom_L: ok read / write fallback via spi success
07:09 PM pcw_mesa: plus you may want the serial port[s] wired in case you want to pass them through for Modbus etc
07:10 PM Tom_L: pcw_mesa, 2.4.0-pre seems pretty solid
07:10 PM Tom_L: pcw_mesa, 3.4.0-pre seems pretty solid
07:11 PM pcw_mesa: its also pretty up to date on new hm2 modules
07:12 PM Thorhian: Okay, sounds good pcw_mesa. I was mainly concerned about powering the board via the the mesa board since powering the pi via the 5v rail through the pin entails little to no protection from what I've read.
07:13 PM pcw_mesa: As long as you have a decent 5V power supply [maybe with crowbar] it should be OK
07:14 PM Thorhian: Crowbar lol?
07:15 PM skunkworks: i ran it for a while through the gpio..
07:16 PM Tom_L: well you're a daring soul
07:16 PM Thorhian: :/
07:17 PM Thorhian: Well, the Pi is compiling LinuxCNC at the moment.
07:36 PM skunkworks: also ran the fan from the 5v gpio header
07:36 PM skunkworks: I mean - if you have a decent power supply - it shouldn't matter.
07:39 PM Tom_L: skunkworks, did you try that GLZ utility?
07:39 PM Tom_L: it's pretty cool
07:42 PM skunkworks: no - not yet
07:42 PM skunkworks: give you all kinds of info?
07:46 PM Tom_L: yeah
07:46 PM Tom_L: core useage, temp, freq
07:46 PM Tom_L: voltage
07:52 PM _unreal_: do any of you guys know much about switching psu's?
07:52 PM _unreal_: I have one that has power fail, and RESET pins
07:52 PM skunkworks: sync: I think you were right - the power supply (5v/24v) doesn't have a connection between the commons. I bet that is why the line driver blew out..
07:52 PM _unreal_: not sure what they do
07:52 PM _unreal_: or how to control them
07:53 PM Tom_L: _unreal_, pc psu?
07:53 PM _unreal_: pc no but it is a 12/5v psu
07:54 PM Tom_L: power fail might be like the 'good power' wire on a pc psu
07:54 PM Tom_L: reset likely cycles it
07:54 PM _unreal_: it came from some camera surveillance hardware
07:54 PM _unreal_: dont know what they do
09:37 PM Thorhian: What kind of jitter should I expect to get on the RPi?
09:39 PM XXCoder: i dont remember but it was pretty good when i saw someone state it here
09:40 PM Thorhian: Right now with stuff going in the background I'm getting around 78034ns on the servo thread and 58091 on the base thread. I'm running the latency test atm.
09:43 PM Thorhian: I don't think those numbers are good lol
09:43 PM XXCoder: not very
09:43 PM Thorhian: I guess more tweaking will be required lol
09:44 PM XXCoder: yeah
09:51 PM Tom_L: Thorhian, https://gnipsel.com/linuxcnc/uspace/rpi4-rt.html
09:52 PM Tom_L: near the bottom you can edit the /boot/cmdline.txt file and get a little improvement
09:52 PM Tom_L: i would't plan on doing alot more with it while running lcnc anyway
09:54 PM Thorhian: Tom_L: I actually followed that guide. I used those configs.
09:54 PM Thorhian: Also, now I am back on my desktop.
09:59 PM Thorhian: I think I'll check out skunkworks' videos again for some of the tweaks he used to hopefully get the results he was getting.
10:00 PM Tom_L: he overclocked his for one thing
10:00 PM Tom_L: 1800 instead of 1500
10:00 PM Tom_L: voids warranty
10:01 PM Thorhian: Actually max clock is 1.6GHz, and I don't mind voiding the warranty with some overclocking lol
10:01 PM Tom_L: different kernel or something may open it up to more
10:01 PM Tom_L: also gpu set to 600
10:02 PM Thorhian: But keeping the thing at 1.6GHz and dsiabling frequency scaling like he did initially would probably help a lot.
10:02 PM Tom_L: over voltage 6
10:03 PM Tom_L: https://www.tomshardware.com/reviews/raspberry-pi-4-b-overclocking,6188.html
10:05 PM CaptHindsight: Tom_L: I have mine at 2GHz
10:05 PM Tom_L: what temp?
10:06 PM CaptHindsight: with his same heatsink it's never over 38C at the surface
10:06 PM CaptHindsight: in a 22C room
10:06 PM Thorhian: skunk's heatsink?
10:06 PM Thorhian: or mine?
10:06 PM Tom_L: cooling fan?
10:07 PM CaptHindsight: yes the heat as skunks
10:07 PM CaptHindsight: no fan
10:07 PM Tom_L: i've got the same heatsink
10:07 PM Tom_L: runs ~48-50c
10:07 PM Tom_L: running yt etc
10:08 PM CaptHindsight: I'm running Gentoo
10:08 PM Thorhian: Lol Gentoo
10:09 PM CaptHindsight: https://github.com/sakaki-/gentoo-on-rpi-64bit
10:09 PM CaptHindsight: somebody keeps a binary version going
10:09 PM CaptHindsight: it's easy to trim
10:10 PM CaptHindsight: i still have to get around to cross compiling on a Ryzen
10:11 PM Thorhian: I love my 3700X :)
10:11 PM CaptHindsight: Tom_L: how are you reading temp and where?
10:11 PM CaptHindsight: I have a temp probe on the outside of the case/heatsink
10:11 PM Tom_L: https://www.geeks3d.com/20191004/gl-z-0-5-0-released-raspberry-pi-cpu-and-gpu-monitoring-improved/
10:12 PM CaptHindsight: and i also use an touchfree IR thermometer
10:12 PM Thorhian: I mean, you won't get an accurate read of the chip's temp if you are reading from the heatsink.
10:13 PM CaptHindsight: yes, there is thermal resistance between heatsink and CPU case and die
10:14 PM CaptHindsight: the resistance is constant
10:14 PM CaptHindsight: die temp is higher, forget the delta
10:14 PM CaptHindsight: <10C
10:15 PM Thorhian: I mean, 5C ~ 10C would be significant.
10:15 PM CaptHindsight: still under 50C at the core at 2GHz
10:15 PM Thorhian: That's pretty good.
10:16 PM CaptHindsight: i forget how accurate the thermal diode is in the CPU core of the Rpi4
10:16 PM CaptHindsight: +- 1 C maybe
10:16 PM Tom_L: what's that 4th chip they recomend a heatsink on? i noticed the heatsink didn't have a pad for it
10:17 PM CaptHindsight: over 10-60C
10:17 PM Thorhian: I'll definitely be adding active cooling to it or the container it is in though. That would probably help a good amount with the heaksink.
10:17 PM CaptHindsight: cooler the better
10:17 PM Tom_L: for my purpose i think what i have is sufficient
10:18 PM CaptHindsight: but now that the Allwinner has had its MCU reverse engineered...
10:18 PM Thorhian: Allwinner?
10:18 PM CaptHindsight: if I try to build a CNC controller with ARM it will be one of those
10:18 PM CaptHindsight: Thorhian: https://cnc32.ru/orangecnc/
10:19 PM CaptHindsight: we had it working on those back in 13-14 but we didn't have specs to the MCU then
10:20 PM Thorhian: I see, I wonder who made the Allwinner....
10:20 PM CaptHindsight: the Allwinners have up to 8 cores + a Microcontroller like the BBB
10:20 PM CaptHindsight: Allwinner makes Allwinner, it's a Chinese fabless processor co
10:21 PM Thorhian: I see, another random chinese silicon company.
10:21 PM CaptHindsight: there are several low cost boards with RPi headers that use various Allwinner processors
10:22 PM CaptHindsight: https://en.wikipedia.org/wiki/Allwinner_Technology
10:22 PM CaptHindsight: the Allwinner with the MCU also have a mali GPU which also has open 3D drivers now
10:22 PM Thorhian: I remember when Mali GPU drivers were a nightmare lol
10:23 PM CaptHindsight: so you can have real time on one core, software stepping on the MCU and high res high frame rate GUI on the GPU and all using open source
10:23 PM CaptHindsight: yeah they were
10:23 PM CaptHindsight: a lot has happened since 2014
10:23 PM Thorhian: The Dolphin Emulator devs hated Mali back in the day. I bet it's a lot better now though lol
10:24 PM XXCoder: now that people got entire source of some consoles, including firmwire, it wont be issue long
10:24 PM XXCoder: up to wii I think
10:24 PM XXCoder: and as old as n64
10:25 PM XXCoder: but not gc, its source is included in wii though so they got wii version of gc
10:25 PM Thorhian: I mean, I was refering to the Mali drivers being a piece of crap making it near impossible to be able to run decent GL code for Dolphin on android in the past.
10:25 PM XXCoder: ahh yea
10:25 PM CaptHindsight: https://panfrost.freedesktop.org/
10:26 PM CaptHindsight: https://gitlab.freedesktop.org/panfrost
10:26 PM Thorhian: XXCoder, were you involved with Dolphin development at all?
10:26 PM XXCoder: nope
10:26 PM CaptHindsight: https://gitlab.freedesktop.org/lima
10:26 PM XXCoder: last week i think or 2 weeks ago there was HUGE leak of ninedo source code though
10:27 PM CaptHindsight: the only issue so far is that the Allwinners only support 2GB of DDR
10:27 PM Thorhian: That pretty lame.
10:27 PM Thorhian: That's*
10:27 PM CaptHindsight: they don't have the external address lines to access over 2GB
10:27 PM XXCoder: ypu managed to download it? heh
10:28 PM XXCoder: 2 tb is crazy lol
10:28 PM Thorhian: What are you talking about XXCoder?
10:28 PM XXCoder: nindento source code leak
10:29 PM Thorhian: Yeah but who were you asking "ypu managed to download it?"
10:29 PM XXCoder: oh you heh
10:30 PM Thorhian: Nah man, that's asking for trouble, and I don't even have the space lol.
10:30 PM XXCoder: i wanted firmware because i was curious
10:48 PM CaptHindsight is now known as PantomimeHorse
10:55 PM PantomimeHorse: most of you guys are in opening states
10:55 PM PantomimeHorse: https://www.nytimes.com/interactive/2020/us/states-reopen-map-coronavirus.html
11:06 PM skunkworks: wi opened
11:07 PM skunkworks: driving home all the bars were packed.
11:07 PM veegee: Yup powerCON is what I'll use for my power tools
11:07 PM veegee: https://www.youtube.com/watch?v=riy85f8Qov4
11:08 PM PantomimeHorse: skunkworks: yeah saw that
11:09 PM PantomimeHorse: skunkworks: read that they opened last night right after the state supreme court over ruled the guberner
11:09 PM skunkworks: yep
11:09 PM PantomimeHorse: hopefully things will not be bad in 1-3 weeks
11:10 PM PantomimeHorse: we were just shy of the state line earlier, 100ft
11:12 PM skunkworks: a friend in the know said wi numbers were close to looking good. like we could have reopened soon. but now thinks the numbers will go back up. time will tell
