12:33 AM veegee: Easy enough to wind a transformer with 18 or 24 low voltage outputs and attach them to cheap DC/DC converter boards you can buy for like $5 each
12:39 AM veegee: Or linear regulators for even simpler output and tighter line/load regulation
12:39 AM veegee: Hmmmm could even get away with a high current single power source and solid state relays to constantly rotate between each cell. Like active cell balancing. Lots of fun ideas
01:28 AM Deejay: moin
03:55 AM fog81: hello
03:57 AM gloops: morning
04:01 AM fog81: i am reading about mesa ethernet cards - it should be connected directly to the network card. So that mean one mesa card per ethernet card. Can i have multiple ethernet based mesa cards?
04:02 AM fog81 is now known as fogl81
04:05 AM gloops: plenty here who can answer, when they wake up, i dont use ethernet
04:07 AM fogl81: :)
04:07 AM fogl81: ok, maybe when yomeone sees this: i was reading this instructions: https://forum.linuxcnc.org/27-driver-boards/35592-mesa-ethernet-setup-for-7i92-7i96-7i76e-and-other-ethernet-mesa-boards
04:08 AM Tom_L: yes you can
04:08 AM fogl81: maybe this is meant for programming only?
04:09 AM Tom_L: no reason to have more than one though
04:11 AM fogl81: Why, depends on what you wnt to to do. So you can use more of them connected with a switch
04:56 AM jthornton: morning
04:56 AM XXCoder: hey
05:16 AM TekniQue: fogl81: you can use them on a switch, the recommendation is just that the switch isn't used for any other network traffic
05:18 AM XXCoder: jthornton: little bit of maybe good news
05:19 AM XXCoder: they are restarting certain set of contracts
05:19 AM XXCoder: my friend and coworker is rehired
05:19 AM XXCoder: i hope I will be soon
05:22 AM jthornton: good news
05:22 AM XXCoder: yeah somewhat, since they are still under massive time cut
05:49 AM Tom_L: morning again
05:50 AM Tom_L: fogl81, you don't want to use a swotch
05:50 AM Tom_L: 31 & snow
05:57 AM XXCoder: jt whats sad is that he cant even start working yet, his wife got covid
05:57 AM XXCoder: he dont think he got it, but he wont go till test says he dont
05:58 AM jthornton: yea that's sad
05:58 AM XXCoder: more and more people on irc and discord know someone personally with it now
05:58 AM jthornton: we have rain/snow but it won't stick
05:59 AM jthornton: it's hard not to know someone that had it with 5% of the state testing positive here
06:00 AM XXCoder: yeah
06:21 AM jthornton: yea my M570 should show up today
06:22 AM XXCoder: cool :)
06:22 AM XXCoder: seems covid is making phone companies cut prices a lot
06:23 AM XXCoder: i ordered a phone for essentally free from google fi
06:23 AM XXCoder: 100 dollar off, then 149 credit. phone is 249
06:31 AM jthornton: what phone did you get?
06:32 AM XXCoder: moto g power
06:32 AM XXCoder: not exactly high end, but newer than moto x4
06:45 AM jthornton: I still use my galaxy s4 lol
07:17 AM Tom_L: you have to change batteries in the S4 yet?
07:18 AM XXCoder: i still have my s4 too, but its been retired for qyite a while
07:25 AM jthornton: ran over one with my spyder then knitted my wifes and mine together and changed the battery and camera
07:27 AM XXCoder: once my new phone arrives I might use my x4 as outside camera because im curious
07:34 AM mrec: Hi, the linear scales on my mill show up an error of 0.4mm on 160mm is there a way to configure that in linuxcnc?
07:35 AM mrec: (it's the Z axis)
07:35 AM jthornton: is the scale wrong or the pitch of the screw varies?
07:36 AM mrec: I put my cards on the linear scale that it should be somewhat ok, the entire device is very cheap.
07:36 AM mrec: I guess the leadscrew might be the issue
07:37 AM jthornton: I mean the scale of steps per unit
07:38 AM jthornton: if the leadscrew varies you can map it, if the overall scale is wrong you can change that in the ini usually
07:38 AM mrec: scale steps is supposed to be 0.05mm
07:38 AM jthornton: hmm I may not understand the question exactly
07:39 AM mrec: I think the leadscrew might be a little bit off
07:39 AM mrec: 0.4mm/at 160mm
07:40 AM jthornton: http://linuxcnc.org/docs/2.8/html/config/ini-config.html#_joint__lt_num_gt_section
07:40 AM jthornton: if it is consistently off then change the scale on that axis
07:41 AM jthornton: if it varies then use a comp file
07:41 AM mrec: thanks!
07:42 AM jthornton: np
07:42 AM * jthornton goes to start the day
07:44 AM mrec: time to end the day soon here.
08:44 AM gloops: usually takes quite a bit of tweaking the SCALE to get good accuracy, tiny changes
08:45 AM gloops: you can also compensate for backlash if thats the issue
08:46 AM mrec: first of all I need to cut some brackets to replace the plastic prints, afterwards I'd like to replace the leadscrews with ballscrews (the ballscrews are already here).
08:46 AM gregcnc: right. first it depends on the mechanics
08:51 AM gloops: so this is one of those machines that makes its own superior replacement
08:54 AM mrec: I'm already impressed that all axis are moving :-)
08:55 AM mrec: The PC is second hand for 30$ dualcore 2.5ghz and no crashes yet.
08:57 AM gloops: always a bonus when it actually works lol
09:48 AM mrec: are there any latticesemi pcie devices available for linuxcnc?
09:48 AM mrec: I'm currently using the parallel port
10:08 AM jymmmm: Morning
10:27 AM unterhaus_: I'm trying to decide if I should get a dremel 4300 or a proxxon. The proxxon reviews on amazon are horrible though
10:28 AM unterhaus_: amazon comparible items include $35 units
10:30 AM Rab: Dremel is pure garbage. The Proxxon stuff I have used is noticeably better quality. Proxxon is more expensive, though. I think the Proxxon tools equivalent to a basic Dremel are around $100-150.
10:31 AM Rab: I believe the next level up in quality is a name-brand flex-shaft tool like Foredom.
10:35 AM Rab: Specific Dremel gripes: aluminum collets, easily deformed and terrible runout. Bearings located in plastic housing, high vibration.
10:37 AM Rab: The Proxxon tool I have has steel collets and a cast metal nosepiece to locate the front bearing. It's very quiet and has extremely low vibration and runout. I use it with 0.25mm carbide drills at 20K RPM, and don't usually break one aside from operator error.
10:40 AM unterhaus_: the only proxxon I see costs $110
10:41 AM unterhaus_: same as the dremel 4300
10:42 AM unterhaus_: dremel review has some people that say it burns out quickly just like the proxxon
10:42 AM unterhaus_: I would like a foredom, but I think my spouse would panic if I bought one right now
10:43 AM unterhaus_: there are foredom clones for <$100
10:44 AM roycroft: i've burned up more dremels than i can count
10:44 AM roycroft: i finally dumped them and got a foredom about 10 years ago, and the foredom has performed flawlessly ever since
10:45 AM roycroft: the proxxon tools are supposed to be really good, though
10:45 AM roycroft: i'd say you'll be money ahead as soon as you get a foredom
10:46 AM unterhaus_: yeah, they are about $300
10:46 AM roycroft: i certainly invested at least 2-3x as much in dremels over the years as my foredom tool cost
10:47 AM roycroft: dremels are sort of ok for "peck" cutting, i.e. axial cutting
10:47 AM unterhaus_: amazon picks for rotary tool is the dremel 4300 for high end and a wen for $20 including a flex shaft
10:47 AM roycroft: as long as your tooling is not too small
10:47 AM unterhaus_: some people I know use a drywall router
10:47 AM roycroft: but for radial loads dremels are useless
10:49 AM unterhaus_: I certainly wore mine out, but it took more than 20 years
10:49 AM unterhaus_: actually bought and burned one up during that time too, first use
10:49 AM Rab: unterhaus_, I have a cheap $20 knockoff tool with a flex shaft. It hasn't died yet, but I wouldn't describe it as good.
10:49 AM unterhaus_: I guess I got my money's worth out of the one I have now, but it's worn out
10:50 AM Rab: The only advantage of Dremel is that you can buy accessories locally. I lost a collet for my Proxxon tool and had to order a new set from Amazon.
10:50 AM roycroft: perhaps i've just had a bad run of luck with dremels, but ehey were more infuriating than useful to me
10:51 AM roycroft: the last straw, for example, that got me to finally get a foredom, was ironically a jobsite failure, where a foredom is awkward to use
10:51 AM roycroft: it was a brand new dremel
10:51 AM unterhaus_: luthiers use dremels more than any other type of rotary tool
10:51 AM roycroft: as in i went and bought it specifically for this
10:51 AM roycroft: i needed to do a little grinding on a door jam latch
10:52 AM roycroft: it was brass, and i just needed to remove a few thousandths off one edge so that the door latch would function properly
10:52 AM roycroft: the tool started smoking after only a couple minutes of radial grinding
10:53 AM roycroft: i took it back to the store, had to argue with them about whether i had "abused" it, and finally got my money back
10:53 AM unterhaus_: similar experience with the one I burned up. I might get a $20 to get me by
10:53 AM roycroft: and i ended up using a file and spending a bunch of time finishing that job
10:53 AM unterhaus_: I think you have to baby them in a job like that
10:53 AM roycroft: i don't do jobsite work much these days
10:54 AM roycroft: but when i got the foredom tool i got a hanger rod for it, and mounted the rod on a small cart that i can wheel around my shop
10:54 AM roycroft: i got the pedal control for it as well
10:54 AM roycroft: and i love it
10:55 AM roycroft: if i were mounting something like that on a cnc machine, though, i'd think about a proxxon, so i would not have to deal with hanging the motor and routing the flex shaft
11:09 AM unterhaus_: the $20 doesn't fit dremel accessories
11:46 AM unterhaus_: I totally forgot how to fusion 360
12:03 PM unterhaus_: I am modifying a salsa fork, and it has stainless dropouts
12:03 PM unterhaus_: I can't imagine they used stainless fork blades, but you never know
12:03 PM unterhaus_: I guess once I find out if brass sticks to it I will know
12:17 PM unterhaus_: at least the dremel 4300 has 2 bearings on the business end, unlike the cheap ones
12:17 PM unterhaus_: no wonder the bits flail so badly
12:18 PM unterhaus_: but you can replace the armature for $20
12:23 PM roycroft: yes, that's the problem with most dremels - the spindle is not well-supported and has massive runout
12:36 PM selroc: hello
12:36 PM miss0r: o/
12:36 PM Tom_L: o_o
12:38 PM miss0r: The vocabulary of this place isn't what it used to be...
12:38 PM Tom_L: certainly not
12:38 PM * miss0r is having some serious issues with this ridiculous project where I somehow got dragged into setting up a windows 2019 domain server with 5 workstations and roaming profiles.
12:39 PM miss0r: I've never done this stuff before. AND it is not working
12:39 PM miss0r: The underlying linux server, on which this windows stuff is running in a virtual machine is(of course) perfect...
12:40 PM roycroft: nothing is perfect, especially operating systems
12:41 PM miss0r: that is true. but linux is pretty damn close :)
12:42 PM roycroft: actually, it's pretty much a crappy mess
12:42 PM roycroft: but it's better than many
12:45 PM rs[m]: domain server for 5 workstations seems to be overkill
12:47 PM roycroft: it makes the roaming bit easier
12:47 PM miss0r: rs[m]: agreed. But the server is going to get an installation of some accounting software that uses the domain for user rights in its database. Basically the only way to run it
12:48 PM roycroft: i don't deal with windows server, or any windows products, any more
12:48 PM roycroft: but when i did i charged extra for having to deal with it
12:48 PM roycroft: and it took me a lot longer
12:49 PM roycroft: because windows
12:49 PM rs[m]: I'm using freeipa at home for two users, so I can understand the temptation...
12:49 PM roycroft: an almost impossible operating system to administer
12:49 PM rs[m]: real men don't click!
12:49 PM miss0r: hear hear :D
12:50 PM roycroft: i'm trying to sort out how to deal with file sharing here, and i'm just one person
12:50 PM roycroft: i have a file server and sync my data to it
12:50 PM miss0r: I do like using linux, but I have just resigned to windows on most workstations, because of software :)
12:50 PM roycroft: and my laptops (i have two of them now) and imac sync to each other
12:50 PM roycroft: but i also have another imac now, that is running linux mint
12:50 PM roycroft: and i need access to the files on that machine as well
12:51 PM rs[m]: that is one reason for freeipa, it takes care of kerberos (for nfs, email) and certificates and all that stuff
12:51 PM roycroft: the problem is that i need some of the files when i'm not at home
12:51 PM roycroft: and sometimes not on the internet
12:51 PM roycroft: so even a vpn would not work
12:51 PM roycroft: there used to be a brilliant solution for this - afs (andrew filesystem)
12:51 PM roycroft: but nobody uses it any more
12:52 PM roycroft: for some of my stuff i have a gitlab server, and just mange the files with git
12:52 PM rs[m]: and there was an andrew window system IIRC, by CMU
12:52 PM roycroft: but that doesn't work well for a lot of my stuff
12:52 PM rs[m]: I sync stuff around with syncthing
12:53 PM roycroft: oddly, i use the gitlab stuff the most with my cad files, which are outwith git's best use
12:53 PM roycroft: i have to install the lfs extension to deal with them
12:53 PM roycroft: what i want is for the files to live on the file server
12:54 PM roycroft: and when i need to work on something away from home, i can just copy the files i need to work on onto one of the laptops, do what i need to do, and have it automagically sync everything when i'm back on the local network
12:54 PM roycroft: afs does that
12:54 PM roycroft: nothing else that i know of does it
12:54 PM roycroft: my macbook pro ran out disk last night
12:55 PM roycroft: in /
12:55 PM roycroft: which is not good
12:55 PM roycroft: and i really don't need most of the files that live on it
12:55 PM skunkworks: long and painful https://www.youtube.com/watch?v=RErLu73-Xno
12:55 PM roycroft: well, i don't need them to live on it
12:55 PM roycroft: i need them to be accessible
12:55 PM roycroft: and live on the file server
12:56 PM unterhaus_: I'm giving up on wine and just installing windows on a cheap ssd
12:56 PM roycroft: i think we all told you to do that at least a day ago :)
12:56 PM unterhaus_: wine doesn't like 16 bit programs much
12:56 PM unterhaus_: you were the only one
12:56 PM rs[m]: i access fileserver(s) via nfs
12:56 PM rs[m]: stuff that i need offline i sync onto the laptop
12:57 PM roycroft: that's fine, rs[m], but it doesn't handle the bit about taking a hierarchy on the road and having it automagically resync upon return
12:57 PM rs[m]: roycroft: syncthing does
12:57 PM roycroft: afs does all of that automatically and seamlessly
12:58 PM rs[m]: i used to use unison for that stuff, but syncthing just works in the background
12:58 PM roycroft: i must have been speaking for the whole channel then, unterhaus_ :)
12:58 PM roycroft: i think i looked at syncthing the other day
12:58 PM roycroft: one moment
01:01 PM roycroft: yeah, that's what i was looking at
01:01 PM rs[m]: it doesn't do users, so you have to run it as/for every user which sucks on the server
01:01 PM roycroft: it's available as a plugin for freenas
01:01 PM roycroft: i'm a single user, so that's not a big deal
01:01 PM roycroft: i'll take another look at it
01:01 PM roycroft: i forget why i didn't spend more time with it upon first overview
01:01 PM rs[m]: I'm just a happy user
01:02 PM roycroft: it has clients for linux and macos
01:02 PM roycroft: and maybe even windows
01:02 PM rs[m]: i think it also runs on android
01:02 PM roycroft: i don't really care about the windows part
01:03 PM roycroft: i only run windows in virtual machines, and i have file sharing between the guest and the host for when i do that
01:03 PM roycroft: and i'm trying to not run windows at all
01:03 PM roycroft: unfortunately, until i find some good cad software for linu, i'll need to continue using windows
01:03 PM roycroft: linux
01:04 PM rs[m]: yeah, some real cad solution would be nice
01:04 PM roycroft: the 'x' key on this keyboard barely works, so on top of my usualy typos, that letter is going to be missing most of the time
01:04 PM roycroft: freecad has so much potential
01:04 PM roycroft: but it's not there, and probably won't be for another decade or two
01:08 PM roycroft: it would be nice to have a decent 2d cad application for linux as well
01:08 PM roycroft: librecad is supposed to be ok
01:09 PM roycroft: but i don't even think it's comparable to some really old autocad releases
01:09 PM roycroft: i still use autocad 2008, because it does what i need to do and i can't justify the cost of upgrading it
01:09 PM roycroft: but by current standards, acad 2008 is fairly primative
01:12 PM unterhaus_: does grub just find a windows install and show it on the menu?
01:13 PM unterhaus_: I guess I'll find out
01:13 PM Rab: I have had that happen.
01:15 PM unterhaus_: the tutorial I just watched basically just showed how to make the grub menu visible
01:15 PM rs[m]: unterhaus_: it needs to be found by whatever generates the grub menu files
01:15 PM unterhaus_: could have been 37 seconds long instead of 10 minutes
01:15 PM unterhaus_: he did run a program
01:15 PM unterhaus_: os probe or some such
01:17 PM unterhaus_: os-prober
01:17 PM roycroft: i thought you were going to install windows in a vm?
01:22 PM unterhaus_: it's a lcnc computer, don't want to turn on virtualization for latency reasons
01:23 PM unterhaus_: and also, I have a small hard drive
01:24 PM unterhaus_: hopefully I don't have to run winders very often
01:28 PM unterhaus_: I think microsoft has docker installs where the license expires in a month
01:29 PM unterhaus_: might as well have it available though
01:30 PM JT-Shop: before the name changed to libracad it worked pretty well
01:31 PM JT-Shop: roycroft, what os are you running acad 08 on?
01:33 PM * JT-Shop notices break second appears to be over with so back to work
01:41 PM rs[m]: JT-Cave: qcad is still a thing and is much more polished thatn librecad
01:42 PM JT-Shop: can you get qcad for recent OS's?
01:42 PM roycroft: i used qcad on mac os
01:42 PM roycroft: i even paid for it
01:42 PM roycroft: it was quite primative
01:42 PM JT-Shop: and I agree qcad is much better than libracad
01:42 PM rs[m]: JT-Shop: you mean recent linuxes? yes, definitely
01:42 PM roycroft: if qcad is better than librecad then i don't need to look aat librecad
01:43 PM JT-Shop: I need to uninstall librecad and install qcad
01:43 PM roycroft: and i've not used qcad in several years, so perhaps it's improved
01:45 PM JT-Shop: https://qcad.org/en/download
01:47 PM roycroft: hmm qcad has some cam support now
01:47 PM roycroft: that makes it more interesting
01:50 PM DaViruz: roycroft: oh, that looks pretty usable
01:50 PM roycroft: i wonder if my old qcad pro license works on the current vrersion
01:50 PM roycroft: i may install qcad tonight and see if it's improved enough to use
02:08 PM Tom_L: JT-Shop, get your mouse yet?
02:21 PM JT-Shop: yea
02:21 PM JT-Shop: what did you say you configured the up/down keys for?
02:22 PM JT-Shop: I also see you can configure it by the software too
02:35 PM unterhaus_: my router is at the store but it's not ready for me to pick up for some reason
02:47 PM Tom_L: JT-Shop, i use their software to configure both the buttons for middle mouse button
02:57 PM Tom_L: listed under 'other'
03:20 PM roycroft: well, i can't find an activation key or anything for qcad, but i bought it in 2008
03:20 PM roycroft: so i don't know what the deal is
03:20 PM roycroft: it's version 2.2.1.0
03:31 PM roycroft: aah, they don't do activation keys
03:31 PM roycroft: i get a download link and just download the app
03:31 PM * roycroft emails them for update info
03:33 PM unterhaus_: it doesn't appear that they update for free
03:33 PM unterhaus_: but you can use it forever
03:34 PM roycroft: correct
03:34 PM roycroft: they do offer a 30% discount on updates though
03:34 PM roycroft: which is why i just emailed them
03:34 PM roycroft: also, i need to know if i can install both the mac os and linux versions
03:35 PM roycroft: they permit installing on multiple computers for a single user, but it's not clear whether that includes multiple platforms
03:37 PM roycroft: that 30% discount applies to all their products, so i should be able to get the cam app for 30% off when the time comes
03:38 PM roycroft: my old version is beachballing though, so i'm not happy about that
03:48 PM roycroft: and qcad just crashed
03:48 PM roycroft: i don't remember that happening before, but that may be one reason i never used it much
03:49 PM roycroft: and i reopened it again, drew a rectangle again, tried to save, and it's beachballing again
03:53 PM roycroft: and it's crashed again
03:53 PM roycroft: so it's utterly useless
03:53 PM roycroft: i'll grab a trial of the current version and see if that works
05:13 PM JT-Shop: I like the comment by the factory owner, the operator is like the maytag repair man now...
05:16 PM Tom_L: becoming more true all the time
05:16 PM JT-Shop: and the best part is come by tomorrow and we will settle up
05:16 PM Tom_L: oh, the spoke factory?
05:16 PM Tom_L: nice
05:16 PM JT-Shop: well if Steve can run 6 machines instead of 1 they are more profitable
05:16 PM JT-Shop: yea
05:17 PM Tom_L: if it keeps china at bay a bit longer more power to him
05:17 PM JT-Shop: time to close up here...
05:17 PM Tom_L: i left you notes on the mouse
05:17 PM Tom_L: pm
05:17 PM JT-Shop: yea I'm all for helping out local factories
05:18 PM JT-Shop: ok heading down to the cave now
05:33 PM XXCoder: Okuma MV45-VBE for 3.6k, but probably can down to 3k in cenetr taxas
05:33 PM XXCoder: fried electrics
05:33 PM XXCoder: may be good project machine for changing to linuxcnc
05:40 PM unterhaus: is that the one on the forum?
05:40 PM XXCoder: he said its posted in user exchange, dunno if thats in forum or not
05:41 PM unterhaus: 220 machine hooked up to 480?
05:42 PM XXCoder: yeah that one then
05:42 PM XXCoder: wonder how the heck that happened
05:42 PM XXCoder: id just assume everything is fried
05:42 PM unterhaus: hard to know
05:42 PM XXCoder: then adjust project according
05:42 PM XXCoder: yeah thats why I said assume :)
05:43 PM unterhaus: I'd have to see a schematic
05:43 PM unterhaus: some of them would fry up front and save the control
05:43 PM XXCoder: yeah. but if rough costs analsys its best to assume everything failed in this case
05:43 PM unterhaus: but I can't see getting more than scrap price for it, which is nothing like $3k
05:44 PM unterhaus: a LOT of magic smoke was released
05:44 PM unterhaus: that's bad
05:44 PM XXCoder: would servos live though that?
05:45 PM unterhaus: I expect the motors are okay
05:45 PM XXCoder: okuma control really is shit, id replace it anyway lol (it errors out if you change tool 1 to tool 1
05:45 PM unterhaus: I think I would want a better looking retrofit candidate, that thing would depress me
05:45 PM XXCoder: that can force you to use unsafe programming, like no tool change at all. which may lead to crash if you change tool to check something
