12:45 AM CaptHindsight: huh small thumbs, now I have to research ape thumbs
01:21 AM NoSpark: I'm planning on adding 2 small stepper motors to my gantry router, to control the height if the dust boot. The head control box has a spare CAT6 SSFTP cable running to it. I don't really need hard realtime control, so I'm concidering using MODBUS based stepper drives. Any thoughts?
01:22 AM NoSpark: I already have a MESA serial daughter card there, but I don't think bit bangin STEP DIR commands would be feasible?
01:23 AM NoSpark: Ideally, I want ot have pretty accurate height control of the boot, so pneumatic actuation is not doable
01:23 AM jpa-: if you don't need much microstepping, bit banging STEP DIR would probably work fine
01:24 AM NoSpark: I don't need sub millimeter, but millimeter precision would be good, you think bit banging would be okay?
01:25 AM jpa-: i think you can bitbang up to 250 pulses per second on MESA cards easily, perhaps even 500
01:25 AM XXCoder: it can be done on cheapest breakout board with cheap drivers honestly
01:26 AM XXCoder: since it barely moves most times
01:26 AM jpa-: you might be able to even customize the FPGA code to add an actual stepper driver code, but that's probably overkill
01:26 AM NoSpark: +XXCoder yeah, I could just add a complete custom solution, but I would hoping to use COTS
01:27 AM NoSpark: Something like this: https://www.omc-stepperonline.com/modbus-rs485-closed-loop-stepper-motor-driver-0-5-7-0a-24-48vdc-cl57rs
01:27 AM XXCoder: BOB with cheapie driver would be less than half that
01:27 AM jpa-: that's fancy, but will definitely work - you can go cheaper though
01:27 AM NoSpark: Cost is not my primary motivator, time is
01:28 AM NoSpark: I never have enough time
01:28 AM jpa-: getting servo error to linuxcnc would be nice so you can detect when something hits it
01:28 AM NoSpark: jpa-: Good point
01:28 AM jpa-: if i was doing it, i might choose screw rise & motor holding current so that it will give way before breaking
01:29 AM NoSpark: I was only planning on using NEMA 23 or 32 motors, so they wont be very rigid
01:29 AM jpa-: though i guess you could just put some breakaway pin
01:29 AM NoSpark: I was thinking of using magnets or loose press fit for mechanical fuse
01:29 AM jpa-: magnets sounds good, especially if you add a hall sensor to stop things if it gets detached
01:30 AM NoSpark: I was to use a solid dust boot, because I only machin sheet stock. I figure I can mod my post processor to give motion commands for the boot
01:30 AM NoSpark: *I want to use
01:31 AM NoSpark: so if the sheet stock is 10mm, just place the boot at 11-12mm
01:31 AM NoSpark: I need to change tools, with different lengths, so it does need to be automatic
01:31 AM rigid: "i think you can bitbang up to 250 pulses per second on MESA cards easily, perhaps even 500" really? That doesn't seem a lot
01:32 AM rigid: i'm bitbanging 55k pulses/s with hal_pi_gpio on rpi4 no problem
01:32 AM jpa-: rigid: in default settings the IO runs at 1 kHz; for faster step speed you use the FPGA stepper code which goes to several MHz
01:32 AM rigid: ah, 1kHz IO
01:34 AM rigid: Has anyone ever used adjustable linear bearings like these https://www.dold-mechatronik.de/media/image/product/224620/lg/linearlager-lmxxuuaj-einstellbar-ausfuehrung-waehlbar.jpg ?
01:34 AM jpa-: NoSpark: IIRC i saw some router use a fancy pneumatic dust boot, where the air pressure pushes the dust boot down and then it has holes in bottom so that it floats above the stock on air cushion; and the air pushing out of the boot bottom also helps make an "air wall" that keeps dust in for vacuum to suck
01:34 AM rigid: are they just adjusted by pressing them?
01:36 AM XXCoder: that frank guy has hose setupo on axis, but its manually moved and locked in place
01:37 AM jpa-: rigid: i would assume you'd put those in a metal block that's been split and the split adjusted with a screw
01:37 AM jpa-: https://www.zyltech.com/2x-8mm-linear-bearing-block-adjustable/ like that
01:40 AM rigid: ah yeah... that makes sense. can't use a block but I'll just use two wide set screws to apply the pressure.
01:44 AM NoSpark: Rigid, keep in mind the load rating, I was blown away by how light duty that style of block is
01:44 AM NoSpark: jpa- do you have a link?
01:45 AM jpa-: NoSpark: tried finding it, unfortunately didn't
01:45 AM NoSpark: dammit, that sounded pretty cool
01:45 AM jpa-: it was some youtube video, they are annoyingly hard to search
01:45 AM NoSpark: agreed
01:47 AM rigid: NoSpark: indeed, it says dynamic 274N / static 392N which is not a ton... literally :)
01:48 AM rigid: but I think it's enough for my small milli-vanilli
01:48 AM NoSpark: Rigid, are they chinesium? IIRC the 16mm ones I looked at had a 50N rating, with a displacement of 0.3mm or so
01:48 AM rigid: there's actually almost no dynamic load at all except the Z-axis when sinking into aluminium. And I think that's my wrong/cheap millbit
01:50 AM NoSpark: okay, just thought I would give you a heads up. I ended up using the MGR7 rails, because it worked out to be only a bit more expencive to use one MGR7 instead of 2 UBR16
01:50 AM jpa-: heh, i can't believe how many "cnc dust boot" videos there are :D
01:50 AM rigid: NoSpark: they are german with displacement of +0µ/-9µ
01:53 AM NoSpark: rigid: wow, not even in the same universe as the ones I was looking at then :)
01:53 AM rigid: NoSpark: i'm using 2 UBR12 and UBR8 for X and Z. And it's just the bearings that cause play. Should be allright. I'm doing aluminium at 30mm/min fine (with a cheap amazon drillbit)
01:54 AM rigid: but when the Z axis lowers into the aluminium, there's horrible vibration for a short time when using an endmill bit.
01:55 AM * rigid has to get decent bits
01:55 AM rigid: ...something that's not flat
01:56 AM rigid: NoSpark: https://www.dold-mechatronik.de/Linearlager-8mm-LM8UUAJ-einstellbar + google translate
02:00 AM rigid: oh, english version: https://www.dold-mechatronik.de/Linear-bearing-LMxxUUAJ-adjustable-version-selectable
02:04 AM NoSpark: How long are your Z axis rails?
02:05 AM rigid: 100mm (effective slide way ~86mm)
02:11 AM NoSpark: Does anyone know if I can run 2 MESA ethernet cards on one host ethernet port? I am thinking I could just add a 7I76E or 7i96s MESA FPGA stepper card to the head, connected over the CAT6 cable, and connect some cheap drives to that. I could swap it wth the 7I66 Smart serial card that is there...
02:12 AM NoSpark: rigid: thought it could have been flex in the rails, but those rails are pretty short, how big is your machine?
02:17 AM rigid: NoSpark: 300 x 180 x 45 mm ... I checked it with a high-speed camera. The X axis has _a lot_ of verticalplay and the Z axis a lot of horizontal play. When the millbit touches the material, it starts cutting shortly but then bumps up a little. The missing sturdiness is giving too much way so it can "land" a little off place causing vibration
02:17 AM NoSpark: can you upload the footage?
02:18 AM rigid: i _think_ it would just work with a normal drillbit that's not flat
02:18 AM rigid: sure. i guess I need a youtube account anyway
02:19 AM NoSpark: even drill bits have a lot of vertical vibration if the cutting pressure is not perfectly constant
02:23 AM rigid: yeah, this is certainly not balanced. I had a hard time balancing the collet/holder thingy on the spindle axle
02:24 AM rigid: ...still some vibration at some resonant RPMs ... I avoid those
03:28 AM NoSpark: do short runs of RS422 encoders HAVE to be run over twisted pair?
04:31 AM Tom_L: morning
05:03 AM JT-Cave: morning
05:53 AM Deejay: moin
06:49 AM bjorkintosh: moin moin
07:34 AM Tom_L: 31F / 62F
07:35 AM bjorkintosh: anyone know of this? https://wiki.debian.org/Hugepages
08:58 AM skunkworks: bjorkintosh: I think I am using hugepages for my qemu/passthrough setup
08:58 AM bjorkintosh: can't seem to figure out why the hell cloning a perfectly working qemu VM makes it dog slow.
09:02 AM skunkworks: I think I am dedicating 1/2 of my main memory to the vm
09:05 AM skunkworks: if I remember right - there are 2 different incantations depending on the archetecture
09:07 AM skunkworks: I was usding this guide https://gist.github.com/Misairu-G/616f7b2756c488148b7309addc940b28?permalink_comment_id=3257565
09:07 AM skunkworks: but this was years ago
09:07 AM skunkworks: (and for a laptop)
09:09 AM bjorkintosh: ah thank you. I'll check it out.
09:51 AM Roguish: bright and clear here today. forecast to almost 70......
09:51 AM Roguish: rain coming in Wed.
09:55 AM roycroft: we may break the record high for the day here
09:55 AM roycroft: overcast, but dry and warm
09:55 AM roycroft: posssibly 20 degrees today
09:58 AM Roguish: oh, you mean 68 F
09:58 AM roycroft: yes
09:58 AM Roguish: we're supposed to be up there too
09:58 AM * roycroft always indicates when he uses parochial units
10:16 AM skunkworks: Took the kids skiing yesterday.. It was 35f
10:16 AM skunkworks: don't know how many more times we will be able to this year
10:18 AM skunkworks: the ski hill just opened in the last week or so
10:23 AM roycroft: yeah, the ski lifts here opened really late this year
10:23 AM roycroft: er, this season
10:23 AM roycroft: some maybe this year
10:24 AM * roycroft is starting work on his wood threading tools this week
10:24 AM Roguish: Mt Ashland, Southern Oregon, just opened like 2 weeks ago.
10:24 AM roycroft: yup
10:25 AM roycroft: and that's really late - it usually opens in november
10:25 AM skunkworks: they would have opened in december - but we got about a week of rain around christmas... Melted all the snow they had.
10:30 AM skunkworks: I need to get into shape.. My knees and
10:30 AM skunkworks: leg muscles didn't like it
10:45 AM Roguish_desk: kjfaslkdjf
11:07 AM Roguish: woopee. just paid my property tax
11:07 AM Roguish: ouch
11:07 AM Roguish: wish I got my money's worth
12:41 PM Rab: rsync -auv /media/iphone/* --exclude=Podcasts /home/rkent/media/iphone/
12:45 PM Rab: oops
01:56 PM Unterhaus__ is now known as Unterhausen
01:59 PM skunkworks: lol.. rsyncing your iphone...
02:00 PM Rab: It's the only way to be sure.
02:00 PM roycroft: there's nothing on my phone worth rsyncing
02:00 PM Rab: No pictures?
02:01 PM roycroft: no, i don't take pictures with my phone
02:01 PM skunkworks: I am in the googleverse... All my important stuff is in the 'gasp' cloud..
02:01 PM roycroft: i have a camera for that, and if i don't have my camera with me, i have my ipad
02:01 PM roycroft: and if i don't have my ipad with me then i don't take the picture
02:01 PM * roycroft stores his stuff in the cloud, but the cloud that lives in his server room at his house
02:01 PM Rab: I keep a camera in my workshop for project documentation, but my phone now takes much better pics than the camera.
02:02 PM skunkworks: and becuase I have a pixel... 31.5 MB of 15 GB used
02:02 PM roycroft: there are automated, encrypted offsite backups of my cloud server
02:02 PM roycroft: i'm going to get a video camera for my shop soon, for documenting projects
02:02 PM roycroft: i'm fairly certain it will be a gopro echo 10
02:03 PM Rab: BTW, I painted my butcher block as you advised, and got the lathe onto the stand this weekend. Looks sharp! http://reboots.g-cipher.net/lathe/image/lathe_block.jpg http://reboots.g-cipher.net/lathe/image/lathe_lifted.jpg
02:03 PM pcw--home: "Does anyone know if I can run 2 MESA ethernet cards on one host ethernet port?"
02:03 PM roycroft: eventually i might upgrade my nikon camera body to one that can do streaming video and has about 20Mp resolution
02:03 PM roycroft: but i don't have $1200 to spare for that right now
02:03 PM pcw--home: You can run up to 4 but it does require a fast host
02:04 PM skunkworks: pcw--home: I know I have run more than one - but had multible nics..
02:04 PM roycroft: that looks greta, rab
02:04 PM roycroft: great, rather
02:04 PM Rab: Thanks!
02:05 PM roycroft: you need a certificate for your hosting site though
02:05 PM Rab: roycroft, why's that
02:05 PM roycroft: i got a complaint when i clicked on the link, and had to tell my browser it's ok
02:05 PM roycroft: more and more browsers are whining about that these days
02:05 PM pcw--home: You need a switch of course (and the hal file needs to issue read-requests rather than read commands
02:05 PM pcw--home: )
02:06 PM roycroft: fortunately the browsers are fine with letsencrypt certs, and those are free and can be automated
02:07 PM Rab: roycroft, that seems like bad UX on the visitor's side but not a technical obstacle, which is my favorite thing to ignore.
02:07 PM roycroft: i'm not saying i agree that a website like yours should require a secure certificate
02:08 PM roycroft: but the masters of the internet have decreed that all sites must have one, and the browsers have capitulated
02:09 PM roycroft: i've found that instead of trying to educate all visitors to the site, it's easier to just install the damn certificate
02:09 PM Rab: For example my HTML uses the visitor's default browser fonts, and therefore tends to look terrible in most browsers, but I don't see that as my problem either.
02:11 PM Rab: roycroft, as long as we're trading friendly warnings, I was going to mention that in my experience GoPros are not ideal for this application.
02:11 PM roycroft: i've avoided considering them until recently
02:11 PM roycroft: there were two major problems that concerned me:
02:11 PM roycroft: 1. they did not perform well in suboptimal lighting conditions
02:12 PM roycroft: 2. their use of extreme wide angle lenses caused a fisheye distortion that i find unacceptable
02:12 PM roycroft: and a third minor problem: they're reported to overheat when in a confined space
02:13 PM roycroft: my understanding is that as of the gopro 10, there is a new processor in the cameras and a new ccd
02:13 PM roycroft: the new ccd takes care of the suboptimal lighting issue
02:13 PM roycroft: and the processor allows them to filter in real time to eliminate the fisheye look
02:14 PM roycroft: as far a heat, i plan on not using it in an enclosed space, and reports are that if it gets its power via usb and not the battery the heat issue goes away
02:14 PM roycroft: and that is something i'd intend to do anyway
02:15 PM roycroft: i don't know that any of those things truly are fixed as of the gopro 10, but that's what i've read
02:15 PM roycroft: if you have other issues with gopros i'd love to hear them
02:16 PM roycroft: my use case is not to produce videos to publish, but to document some of the work i do in my shop so that i can review it privately later
02:16 PM Rab: We have a bunch of them at work, older versions, which we intended to double as streaming cam heads. But 1. the batteries are short lived, so you have to either swap'n'charge or supply external power; 2. the cards fill up, we used HDMI out but that needed an external cable; 3. you have to take the camera out of its case to swap batteries and cards; 4. only a special type of case supports external
02:16 PM Rab: cables; 5. they tend to get very hot in prolonged stationary operation; 6. there is no screen for live preview (maybe there is now).
02:18 PM Rab: Also, I tried to substantiate fisheye correction for the GoPro 10 and couldn't. I did find a rumor that it'll be introduced with the 11.
02:19 PM roycroft: ok, i think most or all of those are fixed by the 10
02:20 PM roycroft: i can buy a door for the camera that lets me pass a usb cable into it so i can run it off the usb source
02:20 PM roycroft: my primary use would be to mount it overhead, above my bench
02:20 PM roycroft: i would not need preview, as i would not tend to be hanging off the ceiling rafters to look at it
02:21 PM roycroft: i can stick a 256GB flash card in it, which should let me store several hours worth of video
02:21 PM roycroft: i'll check again on the fisheye correction, as it would drive me absolutely nuts to have everything fisheyed
02:22 PM skunkworks: Rab: what would you consider better than the gopro?
02:22 PM skunkworks: for a go-pro like device
02:22 PM roycroft: i want to spend <$500 for a camera, preferably <$300
02:23 PM Rab: I would also be concerned that for technical work, the computational correction might still introduce errors. Lots of post-processing software does fisheye correction, including a studio GoPro offered (but seems to have discontinued).
02:23 PM roycroft: and i am still boycotting sony, so that's not an option :)
02:24 PM roycroft: i just installed davinci resolve, but i don't know yet if it does fisheye correction
02:24 PM roycroft: i should imagine it does
02:24 PM roycroft: but i also want to be able to just watch what i recorded without having to run through a post-processor
02:24 PM Rab: skunkworks, I think the GoPro is fine as an action cam. But for stationary use where cables aren't an issue, I think I'd rather use a nice webcam with PC recording, or a network camera.
02:24 PM roycroft: i don't need the type of technical accuracy you do
02:25 PM * roycroft want something self-contained for the shop
02:25 PM skunkworks: I still currently use old pixel phones.. lol
02:25 PM roycroft: i would consider a network camera or something that records on a linux box
02:25 PM Rab: I don't need technical accuracy, personally, but I'm thinking more of analyzing "what went right/wrong in this cut", and it's not bowed from fisheye but it's still a misleading non-straight line.
02:26 PM roycroft: maybe a rpi with a big flash card
02:26 PM Rab: Of course it depends on the type of documentation you want.
02:26 PM roycroft: i have a little time to decide
02:26 PM roycroft: a big impetus for this is when i start doing a lot of marbling
02:27 PM roycroft: i want to record the entire process so i can go back and repeat something i make that i like
02:27 PM roycroft: color accuracy is more important than spatial accuracy for that
02:28 PM roycroft: but fisheye would still drive me bonkers
02:28 PM Rab: https://filmmakingelements.com/lens-distortion-correction-in-davinci-resolve/
02:29 PM roycroft: i'm on a website that says that linear mode, the gopro built-in fisheye correction, is available on the hero 11/10/9/8
02:29 PM skunkworks: a quick google search - seems like kdenlive has fish eye correction
02:30 PM Rab: Resolve seems awesome, but every time I need to edit something it's a very small project and I just use simple OSS programs. I would try it for a larger project, though.
02:30 PM roycroft: i'm just starting to learn about it
02:30 PM roycroft: i would normally go with final cut pro, which now costs the same as davinci resolve, but there's a free, stripped down version of resolve
02:30 PM skunkworks: every time I try to use kdenlive - I swear things are different and I have to re-learn it.. lol
02:31 PM roycroft: i decided to start with that and if i like it and think i need the more advanced features then i'll pay for the full version
02:31 PM roycroft: with apple, the "free" version of final cut pro is imovie, which is pretty sucky
02:31 PM Rab: roycroft, watch out that linear mode isn't just narrow FOV. (Which is one way to get around fisheye, at the cost of resolution and, well, FOV).
02:32 PM roycroft: what i was reading is that there is both a fov adjustment and a fisheye compensator
02:32 PM roycroft: two separate features
02:32 PM roycroft: i'm going to buy something as soon as my expense check shows up, or shortly thereafter, but i still have time to do more research
02:32 PM roycroft: and whatever i buy i'll buy from a vendor to whom i can return it without restocking fees
02:33 PM roycroft: i'm sure i can determine in one day whether a gopro hero 10 will do what i want/need or not
02:33 PM roycroft: or any other camera
02:34 PM Rab: skunkworks, as far as a GoPro-alike, I think the bottom has dropped out of that market and GoPro'
02:35 PM Rab: 's main competition is no-name Chinese GoPro clones.
02:36 PM Rab: Garmin's Virb line was very nice, and better than GoPro of the era in just about every way, but I think Garmin bailed years ago.
02:37 PM roycroft: in a shop environment, having the camera completely self-contained, and waterproof, is a real benefit
02:37 PM roycroft: especially a wood shop that gets dusty
02:38 PM Rab: It's water- and dust-proof until you plug in an external cable. ;)
02:38 PM roycroft: https://www.amazon.com/dp/B08NS8ZKM9
02:38 PM roycroft: that should keep most of the dust out
02:42 PM Rab: I see the 10 does have an integrated preview screen, and an interchangeable mount. The one's I'm familiar with relied on the case for the mount and for waterproofing.
02:42 PM roycroft: it seems that as of the hero 10, most of my concerns have been addressed
02:42 PM Rab: (Earlier GoPros)
02:43 PM roycroft: and the 10 is what i'm interested in because it's less expensive than the 11 or 12, and appears to be sufficient for my needs
02:48 PM roycroft: i looked at gopros a few years ago - back when target were carrying them - and actualy got a little hands-on with them, and thought they were crap
03:01 PM Scopeuk: I have had terrible experience with their customer service
03:02 PM Scopeuk: camera never turned up, courier claimed it lost, a week later magically courier said it was delivered on the first delivery day with a proof of a piece of text in dutch saying it was delivered
03:02 PM Scopeuk: they refused to do anything about it and I had to get my bank to reverse charges
03:03 PM Scopeuk: they also wernt planing to tell me this
03:09 PM roycroft: i won't buy directly from them, but that does speak to their customer service
03:47 PM Gothia1 is now known as Gothia
04:46 PM JT-Shop: https://youtu.be/RDORN0wYL7w?list=PLH4J0b3KfGaMGZTjSdnPqrBoB9dAhIBHK&t=941
04:46 PM JT-Shop: welding bronze is nasty
05:02 PM Tom_L: full of zinc isn't it?
05:03 PM JT-Shop: mostly copper
05:03 PM Tom_L: i lost access to lcnc on the mill yesterday
05:03 PM Tom_L: turned out to be a rights thing on the parallel port
05:03 PM JT-Shop: rights can be a pia
05:03 PM Tom_L: have no clue what would change that
05:04 PM Tom_L: took a while to find it
05:04 PM Tom_L: so now maybe i can put jet on it for testing
05:08 PM JT-Shop: I almost have a gcode parser code done
05:34 PM * JT-Shop calls it a night
06:04 PM XXCoder: ugh
06:04 PM XXCoder: I hate some goverment offices
06:04 PM XXCoder: they make you wait for hours, and make hour feel like a year
06:39 PM Tom_L: JT-Cave, jet doesn't want to load on the mill pc
06:39 PM Tom_L: it gets up to the manual toolchange box and then nothing
06:44 PM Tom_L: it's possible i don't have all the gui libs i need out there
06:45 PM Roguish_desk: shit howdy. i actually did a little machining today.... and didn't frack anything up....
06:45 PM XXCoder: thats a good win
06:46 PM Roguish_desk: all done . time for pizza. ttfn
06:56 PM roycroft: i rough milled some ash today so that it will be ready to mill to final size in a couple days
06:57 PM roycroft: i have a board meeting tonight, so i condider that a significan accomplishment on such a busy day
06:58 PM XXCoder: fun. you did a lot more than me.
06:58 PM XXCoder: I sat at office waiting area for 3 hours
07:04 PM Tom_L: send them a bill for your time
07:04 PM XXCoder: I wish
07:04 PM Tom_L: i would
07:04 PM XXCoder: being a neet my work hours is worth $0 a hour lol
07:04 PM Tom_L: maybe they'll catch on that they're no different than the rest of us that have schedules
07:05 PM Tom_L: if i schedule a time, i expect to honor that time
07:05 PM XXCoder: it wasnt scheduled
07:05 PM Tom_L: doctors & airlines both overbook
07:06 PM Tom_L: well then, that's on you :)
07:06 PM XXCoder: lol well it was faster than making few calls over days
07:06 PM XXCoder: but man wait room so boring
07:06 PM Tom_L: stream yt or something on your phone
07:07 PM XXCoder: nah I dont like yt on phone
07:07 PM XXCoder: I played picross galaxy
07:22 PM XXCoder: its very easy rules, but puzzles can be extremely hard
07:27 PM Unterhausen: I was just playing baduk and my opponent realized I played a very good sequence of moves before I did
07:27 PM Unterhausen: I'm out of practice
07:28 PM Unterhausen: zero look-ahead
07:28 PM roycroft: my doctor is pretty much on time - i'm rather impressed
07:28 PM roycroft: that hasn't always been the case for me, but my current doctor is good about being prompt
