06:46 AM * rdtsc-w mutters "M" while desperately reaching for coffee
06:52 AM rdtsc-w: on the bench today is an ABB 75HP ACH550 drive, which came in with no problem description, has a bad HMI, is set for ACS mode, and appears to be plagued by undersized/weak Vacumschmelze gate-pulse transformers among other issues...
06:54 AM rdtsc-w: The VAC transformers are custom, of course... trying to retrofit a through-hole part; currently getting an overcurrent fault, about to 'scope them
08:25 AM lcnc-relay: <skunkworks8841@> do you stand behind a blast shield while working on them? š
08:28 AM mrec: does anyone have sandblasting experience here?
08:30 AM lcnc-relay: <skunkworks8841@> what is the question? we have a cheap suction type sand plasting box here - plus a couple pressurized tank style for outside use..
08:30 AM lcnc-relay: <skunkworks8841@> (I would always go with the pressure tank style)
08:32 AM mrec: https://snipboard.io/i7gfEv.jpg https://s3.amazonaws.com/i.snag.gy/mLV5OA.jpg
08:33 AM mrec: I wonder is it viable to get all the stuff to sand it myself or would it be better to outsource it?
08:34 AM mrec: the cover is around 70cm (height), the door around 1m
08:34 AM lcnc-relay: <skunkworks8841@> would you use the blaster for other projects? I will tell you this - dad got a truck frame and he paid someone to come and sand blast it - it was worth the money. But something that size - I would do it myself.
08:35 AM mrec: I do not see that I would blast anything else, I mostly work with aluminum at the moment
08:35 AM mrec: of course it might change in the future... but this year no
08:36 AM mrec: I want to paint/powdercoat the entire CNC again
08:36 AM mrec: before the corrosion eats the covers
08:37 AM mrec: they used oil based coolant so the machine structure is absolutely okay but the enclosure is in a poor state
10:23 AM roycroft: my tool is back in eugene this morning
10:23 AM roycroft: so there's a good chance it will be delivered tomorrow
11:04 AM rdtsc-w: doing the ol' multiple-tuck sight-seeing tour eh?
11:05 AM roycroft: it's the usual pattern these days, sadly
11:06 AM roycroft: there's a distribution center in eugene, but it's outgoing only - any incoming mail gets sent to portland for sorting then back to eugene
11:07 AM roycroft: my local letter carrier can't be bothered to deliver parcels on a consistent basis, and whenever she doesn't get around to delivering them on a particular day, instead of doing the worst thing, which is taking it back to my local post office to sit overnight, they do the even worse thing, which is to send it back to the eugene sorting center
11:07 AM roycroft: which sends it back to portland for sorting, as they only accept incoming mail from portland for delivery
11:08 AM roycroft: it's ridiculous but it is my reality
11:13 AM memleak: mrec, if you're only going to sandblast one thing, i wouldn't invest in a sandblaster.
11:14 AM memleak: unless you really don't trust anyone else to do the work.
11:20 AM Rab: I briefly looked into sandblasting to restore a machine tool. (Which is the extent of my experience.) Portable blaster units exist, and can sometimes be rented, but according to the PM forum they make a huge mess and the media should be considered disposable rather than recoverable.
11:22 AM mrec: I will check tomorrow, there's a small company in town which does sandblasting and the owner seems to be friendly
11:23 AM roycroft: i would agree that purchasing a blasting cabinet for one job is likely not a good investment of time and real estate
11:23 AM Rab: A few stories along the lines of "I thought I would just sandblast a truck frame outside and it was a nightmare, nevar again"
11:23 AM mrec: powder coating is like 9 minutes from that place but sandblasting is on the other side of the town, around 45 min driving
11:23 AM roycroft: and even though blasting cabinets are pretty contained, i promise you that if you start media blasting in your shop you will have messes to clean up that you do not expect or enjoy handling
11:24 AM roycroft: the powder coating shops i've used (only a couple) had their own media blasters, and would do that prep work for a slight upcharge
11:25 AM roycroft: so you might check with yours to see if they can handle it
11:25 AM mrec: my reason is just I want to get it done ASAP
11:25 AM mrec: I want to put the head cover of the CNC back on
11:25 AM Rab: The covers in the pics look like good candidates for just using an angle grinder with a flap disk. Not a lot of contours.
11:26 AM roycroft: well if you want it done fast and you don't already own a blasting cabinet you might have trouble with that
11:26 AM mrec: Rab: is sandblasting more gentle?
11:26 AM Rab: mrec, I cannot say.
11:26 AM roycroft: to purchase a good blasting cabinet that will work properly as deliver would take some time - you'll have to order it from a distributor or factory that is likely not close to you
11:27 AM Rab: Are you concerned about removing too much material, or surface finish?
11:27 AM mrec: I'm concerned about removing too much material yes, the sheet metal looks good but that was just a rough inspection what I did
11:27 AM roycroft: to purchase one that you can go pick up at harbor freight or princess auto or the like you'll have to do some remodeling before it is useful, which will involve ordering parts that you likely cannot source locally
11:29 AM mrec: it's no problem to go to the other place just if someone would have said it's so easy that I better do it myself I would have evaluated it further
11:29 AM roycroft: mrec: there are a variety of media you can use from gentle to very aggressive - walnut shells, glass beads, and plastic beads are on the way gentile sie
11:29 AM roycroft: gentle, rather
11:29 AM roycroft: i don't think you need a gentile to do the job properly
11:29 AM Rab: I'm interested because I have an old South Bend lathe that was housed in a corrosive environment. The oily lathe is OK, but the sheet metal panels in the cabinet are almost rusted through in places. Not sure exactly how to remove the paint/rust without tearing up the panels.
11:29 AM memleak: walnut shells??
11:30 AM roycroft: walnut shells are used extensively in media blasters
11:30 AM Rab: yep
11:30 AM memleak: oh holy crap lol
11:30 AM mrec: Rab: seems like we have a very similar situation, the machine itself is fine but the covers are all corroded
11:30 AM roycroft: they are quite useful for removing pigeon poop from bronze statues without affecting the patina, for example
11:31 AM roycroft: on parts walnut shells can remove paint one layer at a time
11:32 AM roycroft: you can also use baking soda for a really gentle blasting experience
11:32 AM roycroft: there are special soda blasting machines
11:32 AM Rab: mrec, looks like the paint is barely holding on. Is it original? Have you considered chemical stripping the paint and passivating the rust, grinding off any flaky stuff?
11:32 AM roycroft: in fact, if you have on small part to clean up and you just need gentile blasting, you might get a hand-held soda blaster from harbor freight
11:33 AM roycroft: it looks kind of like a weed poison sprayer you hook up to a garden hose
11:33 AM mrec: Rab: I have not done anything, it's original yes
11:33 AM roycroft: there's a reservoir that holds the soda, and you hook your air hose up to it, go out into the back yard, and blast away
11:33 AM mrec: the machine is around 23 years old and is running in an area with 64% humidity
11:33 AM mrec: for that I still feel like it looks good
11:34 AM mrec: and the last 4-5 years it was not used at all
11:34 AM roycroft: https://www.harborfreight.com/18-oz-portable-abrasive-blaster-gun-kit-59490.html
11:35 AM roycroft: if you get that make sure your air supply is bone dry
11:36 AM Rab: mrec, I like the idea of letting the powder coating place do the prep work, because I abhor manual labor, but I bet a flap disk would have the job halfway done by now.
11:36 AM roycroft: another advantage of letting the powder coater doing the work is that if there's a problem with the powder coating, there is no finger pointing to be done
11:37 AM mrec: we'll probably go that route after getting the quotation
11:37 AM mrec: roycroft: true
11:37 AM roycroft: if you do your own prep and the powder coat is shite, i guarantee you'll be told that you did not prep it properly
11:38 AM Rab: mrec, do you have good shop air? I believe blasting needs some flow, even that little HF blaster specs 7CFM @ 90PSI.
11:38 AM roycroft: that is also an issue, although for something small you can blast in bursts
11:39 AM mrec: yes the compressor is pretty good.
11:39 AM lcnc-relay: <voiditswarranty@> I manifold two cheap compressors together when blasting. still annoying, but less time between bursts
11:39 AM mrec: I will report back tomorrow after getting the quotation
11:39 AM Rab: That's another factor that steered me away from blasting (or needle scaling).
11:40 AM roycroft: i do both, and my compressor is not terribly impressive - i can push it to 140psi and it has a 60 gallon tank and 5hp motor
11:40 AM roycroft: i don't know what cfm i get because i've modified it so much, but it's a decent size
11:40 AM roycroft: yet it will run constantly if i do much blasting or scaling
11:41 AM roycroft: i've thought about getting a second 60 gallon tank for it so it cycles less frequently when doing that kind of work, but i don't do that kind of work often
11:42 AM roycroft: and i don't really want to allocate the real estate that a second tank would consume, although when i rebuild the roof on my shop i'll have a lot of overhead space, so maybe i could put one up there
11:45 AM rdtsc-w: Once as a teen I decided to sand blast a motorcycle exhaust, then took it to the chromer's. They said it should be dipped for extra cost, but it was just sandblasted, so should be about as clean as it can get, right? Came out looking great, but put it on bike, and bubbled up all over. Lesson learned - let them handle it.
11:46 AM roycroft: this
11:46 AM roycroft: i do the media blasting when i'm going to be shooting the paint
11:47 AM roycroft: for powder coating let the shop do the final prep
11:49 AM mrec: I can fully imagine that they did not have much experience with coating that machine in early 2000, but all the owners in between did not treat the machine well they just let it rot
11:50 AM mrec: yet at that point I'm still surprised that the ballscrews are in a very smooth condition all over when hand cranking it I felt absolutely no bump
11:50 AM mrec: all very smooth
11:51 AM rdtsc-w: oil and grease ftw
11:51 AM mrec: also I think the RS232 19.2k interface protected it a little bit for me the previous owner said the machine is too slow
11:52 AM mrec: after adding the highspeed ethernet option I can run trochoidal without any problem (with 19.2k it just stopped all few seconds)
12:07 PM rdtsc-w: did some temp work at a shop where they had 6 machines starred to a 19.2k RS232 switchbox... select the machine to load, grab a coffee lol
12:07 PM Tom_L: dude... that was blazing fast.. we were on 4800 running surface parts
12:07 PM mrec: must have been a relaxing time
12:11 PM lcnc-relay: <skunkworks8841@> mrec: no you don't
12:13 PM lcnc-relay: <skunkworks8841@> we ran the K&T with the original control and figured out right away that a tape emulator was in our future.. (we made one using the computer printer port)
12:15 PM mrec: I can imagine, though still interesting to see that kind of technology.
12:15 PM Tom_L: before rust was invented to be useful
12:22 PM Tom_L: reminds me of the ticker tape parades we used to see
12:22 PM Tom_L: https://en.wikipedia.org/wiki/Ticker-tape_parade#/media/File:Chicago_Welcomes_the_Apollo_11_Astronauts_(9457411063).jpg
12:26 PM mrec: haha
12:26 PM * roycroft remembers that parade, although he did not attend it in person
12:26 PM Tom_L: iconically used in the movie 'the sting'
12:26 PM -!- #linuxcnc mode set to +v by ChanServ
12:27 PM * Tom_L does too
12:45 PM roycroft: the sun is out again
12:45 PM * roycroft is enjoying this little dry spell
12:46 PM roycroft: an inter-deluge respite, one could call it
12:49 PM xxcoder: rain here lol
12:49 PM xxcoder: was dry last couple days
12:54 PM rdtsc-w: supposed to get down to 13degF tonight
12:54 PM xxcoder: Tom_L: odd. your video, the drill had pretty bad runout.
12:54 PM xxcoder: cool otherwise
12:57 PM rdtsc-w: mrec: https://www.youtube.com/watch?v=jBaMJcATHHY
12:59 PM xxcoder: oh it was few days ago, must have missed the video last time lol. (catching up via discord)
01:02 PM mrec: you can't say that's not cool tech (as long as you don't depend on it)
01:02 PM mrec: I remember the times when c64 games were stored on audio cassettes
01:02 PM mrec: fascinating for me as a kid
01:03 PM mrec: https://youtu.be/jBaMJcATHHY?t=1233
01:03 PM mrec: it will start punching in a few seconds from there
01:03 PM xxcoder: making his own computer. thats cool
01:09 PM roycroft: i've been following the usagi electric channel for a while now
01:09 PM roycroft: it's fascinating stuff
01:09 PM roycroft: and almost makes me want to build a vacuum tube computer
01:10 PM roycroft: but i have enough projects/hobbies going on right now
01:10 PM xxcoder: projects stack overflow avoidance
01:10 PM roycroft: although building a vacuum tube computer would be an excellent excuse to sink a ton of money into some new electronics test gear
01:14 PM Roguish: I'm pretty sure the old Bridgeport Series II I had was originally a paper tape machine with large stepper motors.
01:15 PM bjorkintosh: I used to think vacuum tubes were rare and exotic.
01:15 PM bjorkintosh: Apparently, it's as rare and exotic as lady's shoes. Since I have nothing doing with either, I simply don't know where to find them.
01:15 PM bjorkintosh: ie, they're not rare _at_all_
01:16 PM roycroft: some vacuum tubes are very rare and exotic
01:16 PM Roguish: I have a vac tube amp for music. got it from Monoprice a few years ago. sounds very nice with the Klipsch speakers.
01:16 PM roycroft: most are fairly common, though
01:16 PM roycroft: my tuner has one vacuum tube - a "magic eye" for fine tuning
01:16 PM roycroft: but the rest of my hifi gear is all solid-state
01:17 PM roycroft: for my studio, i have an old lafayette tube tuner that is connected to a wwii vintage tube amplifier/speaker that was used by the associated press
01:18 PM roycroft: i haven't unpacked that stuff yet - i should do that soon
01:18 PM roycroft: if i can figure out which box the stuff is in
01:18 PM Roguish: whatever, as long as you enjoy it
01:18 PM roycroft: i do enjoy vintage electronics
01:18 PM roycroft: but also modern electronics
01:19 PM xxcoder: so, just electrics in general? ;)
01:19 PM xxcoder: old tech do look cool
01:20 PM roycroft: interesting electronics
01:20 PM Tom_L: xxcoder, not odd, it was a crappy bit i grabbed laying on the bench
01:20 PM bjorkintosh: I really wish I knew more about electronics.
01:20 PM bjorkintosh: it's just right out of reach.
01:21 PM xxcoder: ahh makes sense. probbly good idea to test with tool soon dead
01:21 PM bjorkintosh: I know what the components are and how to do some super basic troubleshooting and soldering/desoldering.
01:21 PM roycroft: https://roycroft.us/BrewSystem/IMG_1012.JPG
01:21 PM bjorkintosh: but I can't design anything past a battery and a lightbulb connected with wires
01:21 PM roycroft: that certainly has a "vintage" look
01:22 PM xxcoder: I love that metal/wood combo look
01:22 PM bjorkintosh: damn. you built that yourself?
01:22 PM roycroft: yes
01:22 PM bjorkintosh: very nice, roycroft
01:22 PM roycroft: https://roycroft.us/BrewSystem/IMG_1014.JPG
01:22 PM roycroft: that's the brew system it controls
01:22 PM roycroft: which i also built
01:22 PM lcnc-relay: <skunkworks8841@> Adrians digital basement started with 0 electronics knowledge.. Now he fixes old tv's and computer hardware and explains his thought process/troubleshooting as he goes.. He is very good...
01:23 PM Tom_L: bjorkintosh, don't limit yourself
01:23 PM bjorkintosh: Tom_L: well fine. I guess I can remove the lightbulb and just make a wire hot :-D
01:23 PM * bjorkintosh has done that and found out.
01:24 PM Roguish: roycroft, you're a moonshiner...
01:24 PM xxcoder: nah thats not in middle of wilds, covered with random plants
01:25 PM bjorkintosh: roycroft: was it expensive?
01:27 PM roycroft: https://roycroft.us/ControlPanelWiring/
01:27 PM roycroft: there are some in-progress and finished pics of the control panel
01:27 PM roycroft: the whole brew system was well over $6k
01:27 PM roycroft: i was afraid to add it all up
01:27 PM roycroft: and no, i'm not a moonshiner
01:27 PM bjorkintosh: hahah. it's nice. plc controlled too!
01:27 PM roycroft: i ferment, but i do not distill
01:28 PM roycroft: the panel has some nice interlocking systems, such as it won't power up unless all the valves are closed and all the heaters and pumps are turned off
01:29 PM roycroft: that panel handles 50a of 250v power in a rather wet environment
01:29 PM roycroft: so i was pretty careful about building it to function very safely
01:30 PM xxcoder: wow pretty high power than I expected
01:30 PM roycroft: i have to heat up a lot of water
01:30 PM bjorkintosh: was it your first such build?
01:30 PM roycroft: yes
01:30 PM roycroft: and my last, i strongly suspect
01:30 PM bjorkintosh: really cool, roycroft.
01:30 PM bjorkintosh: sometimes, you only need to build the one plane you know?
01:31 PM bjorkintosh: nothing further.
01:31 PM roycroft: except i had a little fire issue a few years after i built it, and had to rebuild part of the front panel
01:31 PM roycroft: the brew system used to live in my shop
01:31 PM roycroft: i would keep the control panel covered with a towel, so it would not get dirty/scratched up/etc
01:31 PM bjorkintosh: fire from where?
01:31 PM roycroft: one day i was welding on the other side of the shop
01:31 PM bjorkintosh: oh.
01:32 PM bjorkintosh: you lit it on fire yourself :-D
01:32 PM roycroft: and yeah, that one spark decided to fly across the shop about 10m and land on the towel
01:32 PM roycroft: i got it put out fairly quickly but the pid controllers and some of the actuators and indicators were melted
01:33 PM roycroft: those pics are actually the rebuild process
01:33 PM roycroft: originally i had hard wired the chassis connections to the panel connections
01:34 PM roycroft: when i had to do the reubild i took the opportunity to build wiring harnasses for the chassis and panel, and installed plugs so i can easily remove the panel completely if/when necessary
02:48 PM JT-Shop: shiny new Holley has arrived
02:49 PM andypugh_: As in carbutooter?
02:50 PM xxcoder: lol some stuff can go really surpising far. I once got very hot chip from steel milling hit my neck and fall in shirt, and I was easily 30 feet from that cnc machine
02:50 PM xxcoder: it had open top unlike nearly all machines in shop
02:51 PM JT-Shop: as in carburetor yes
02:51 PM xxcoder: hey andy
02:52 PM andypugh_: I decided that I was setting a bad example by running my own lathe on LinuxCNC 2.8.0~pre on Debian Wheezy. So I installed the latest LinuxCNC ISO, which consumed the entire 8GB SSD and was glacially slow. (LinuxCNC and latency was fine, but UI response horrble, and I was having to press the cycle-start and (more worryingly) cycle stop buttons for a couple of seconds to get a response.
02:53 PM andypugh_: It seems like an old Atom (DN2800MT) doesnāt play well with 64-bit Bookworm.
02:53 PM Tom_L: i made a similar upgrade with similar results on a D525
02:53 PM Tom_L: it runs but slow
02:54 PM andypugh_: Now I could try playing about with graphics drivers and such. In fact I did, a bit, but then I got bored and bought a new motherboard.
02:54 PM Tom_L: tried the new RTAI on it and that works equally as well
02:54 PM JT-Shop: I still run my CHNC lathe on Ubuntu 10
02:54 PM andypugh_: I have a D510MO too, that I really should just throw away :-)
02:54 PM Tom_L: i kept the wheezy ssd
02:55 PM andypugh_: Anyway: https://www.mini-itx.com/~N100DC-ITX
02:55 PM Tom_L: but in order to test new bleeding edge (flex) software i had to upgrade
02:55 PM Tom_L: i didn't think asrock were that good. i tried a full size one a while back
02:56 PM andypugh_: Added an 8GB DIMM (as that was the smallest DDR4 I could find) and a 240GB M2 SSD (as that was the smallest I could find) and now have a new LinuxCNC PC ready to put in the cabinet when the temperature next climbs above freezing in the workshop.
02:56 PM Tom_L: this may be a whole different animal
02:56 PM Tom_L: good latency?
02:56 PM andypugh_: Itās wilid! the BIOS screen has graphics, and takes USB mouse input!
02:57 PM andypugh_: Latency is āfineā
02:57 PM andypugh_: 25k when running glxgears and opening YouTube in Firefox.
02:57 PM Tom_L: debian 12 nice and responsive?
02:57 PM andypugh_: 11k when just sat there.
02:57 PM Tom_L: not bad
02:57 PM xxcoder: even th fire scene 8k hd youtube?
02:57 PM andypugh_: Yes, itās all _very_ snappy.
02:58 PM xxcoder: I always liked the fire one for testing latency, its very high resolution AND nearly all video constantly change
02:58 PM Tom_L: i wanted a itx form factor if i ever do upgrade
03:00 PM Tom_L: i have some of their 'brick' power supplies too already
03:00 PM Tom_L: 12v in?
03:00 PM Tom_L: for mine i used their power supply 'plug'
03:00 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/itx/itx3.JPG
03:00 PM andypugh_: Reasons to like this N100DC. 1) DC input, runs from the same 12V as the rest of the control. 2) HDMI and VGA (for my touchscreen, and pre-threaded display cable). 3) Has a parallel port header (in case). 4) Has a PCI slot for my Mesa 6i25. 5) Has an M2 SSD slot so no need for drive brackets, power cables etc.
03:01 PM Tom_L: did the parallel port come with the cable?
03:01 PM Tom_L: i've had mixed luck with my M2 slot on a Gigabyte board
03:03 PM andypugh_: Possible good features are a UART on the motherboard and a serial port on the back panel. Also 6 back-pane USB ports and a further 6 headers on the board (inc 2 x USB3.1)
03:03 PM andypugh_: Tom_L: No, no p-port cable/connector. But I donāt plan to use it anyway.
03:04 PM Roguish: andypugh_, hey, what's up with the linuxcnc buildbot?? why is there anything for bullseye or bookworm???? http://buildbot.linuxcnc.org/buildbot/one_line_per_build
03:04 PM andypugh_: This machine has Ā£1k of Mesa cards in it.
03:05 PM andypugh_: Roguish: Itās a Seb problem. He set up a second buildbot but never made it the main one. Try http://buildbot2.highlab.com
03:05 PM Roguish: and why does it go way back in time to presice, wheezy and jessie.
03:05 PM JT-Shop: does the Asrock N100DC-ITX Mb have a serial port?
03:06 PM Tom_L: the buildbot2 handles newer os
03:06 PM JT-Shop: I need a new mb for the BP
03:06 PM Roguish: I am very aware of Seb's buildbot. it's stuck with master branch way back to oct 4th
03:06 PM andypugh_: JT-Shop: Yes, one back panel, and another as a motherboard header
03:07 PM Tom_L: out of stock at newegg
03:07 PM JT-Shop: nice, my vfd uses serial, I need to put the new GS20 in an use GS2 mode
03:07 PM JT-Shop: amazon has them
03:08 PM Tom_L: the lpt port looks standard and i have cables
03:08 PM Tom_L: (i'm using a 7i90)
03:09 PM Tom_L: probably have some spare ddr4 too
03:09 PM Roguish: andypugh_, why so many failures???? http://buildbot2.highlab.com/buildbot/#/grid
03:09 PM Roguish: waz up?
03:11 PM andypugh_: Roguish: Disk full? cp: cannot create directory 'debian/linuxcnc-uspace//usr/share/locale/zh_TW': No space left on device
03:11 PM Roguish: andypugh_, hey, and it is nice to see you here on the chat line....
03:12 PM Tom_L: some of the build bots run out of virtual space
03:12 PM andypugh_: I have been distracted recently. Too many projects. Too few parents.
03:13 PM andypugh_: Anyone want to buy my parentās old house? Very nice. Built the year Leonardo di Vinci was born (1452)
03:14 PM Tom_L: heh i've seen pics... nice place
03:14 PM andypugh_: Getting that into a sale-able state is eating a lot of my time.
03:15 PM Tom_L: iirc you did alot to it over the years too
03:15 PM roycroft: i might like to, but it's not feasible for me to do so
03:15 PM xxcoder: lol cant afford a house sadly
03:16 PM Tom_L: andypugh_, does that board have any standard sata connectors?
03:16 PM Tom_L: i didn't see any
03:16 PM andypugh_: Yeah. Before: http://www.bodgesoc.org/before1.jpg after: http://www.bodgesoc.org/Slaithwaite2/Cottage_end.JPG
03:17 PM andypugh_: Tom_L: Yes, 2x SATA next to the PCI connector
03:17 PM Tom_L: ok
03:17 PM andypugh_: Inside: http://www.bodgesoc.org/Slaithwaite2/Hall3.JPG
03:19 PM JT-Shop: how much memory did you use with the n100dc
03:19 PM Tom_L: 8g
03:20 PM Tom_L: Added an 8GB DIMM (as that was the smallest DDR4 I could find)
03:20 PM Roguish: andypugh_, ok, I just sent Seb an email. directly to him... he's pretty good about responding..
03:21 PM Tom_L: do you need something from his updates?
03:21 PM Roguish: Tom_L, well, Morely and others push a lot of updates to master. and my mill is on bookworm now....
03:23 PM JT-Shop: andypugh_, does the Asrock N100DC-ITX come with a power adapter?
03:23 PM Tom_L: i doubt it
03:24 PM Tom_L: i have a link to some good ones though
03:24 PM JT-Shop: ok
03:24 PM Tom_L: https://www.mini-itx.com/store/category?type=psu&power=more%201&sortby=price&page=1
03:24 PM Tom_L: i have one that's 8A
03:24 PM Tom_L: and 5A iirc
03:25 PM Tom_L: only that's the euro site
03:25 PM andypugh_: Asrock suggest their own 19V PSU, but Mini-ITX have tested at 12, and 12V / 6A is working fine for me.
03:26 PM andypugh_: Itās a slightly odd DC jack 5.4 x 2.5
03:26 PM andypugh_: 5.5 x 2.5 (centre +ve) I mean
03:27 PM Tom_L: https://www.mini-box.com/AC-DC-power-supplies
03:27 PM Tom_L: that's what i meant to link
03:28 PM Tom_L: the plug could be an issue
03:29 PM Tom_L: some of those bigger bricks have a fan inside
03:30 PM Tom_L: i have a couple of their 'pico psu' too
03:31 PM andypugh_: They seem to be confused. If you look at the spec of their 84W one the plug is 5.5 x 2.5
03:31 PM andypugh_: http://resources.mini-box.com/online/PWR-ACDC-12V-7A-84W/PWR-ACDC-12V-7A-84W-specs.pdf
03:31 PM andypugh_: (drawing right at the end)
03:33 PM lcnc-relay: <voiditswarranty@> worst case digikey can have connectors to you in a day, whip yourself up an adapter. Half the time with single board computers I'm soldering pigtails to it to go into a terminal block anyway.
03:35 PM Tom_L: iirc mine have that triangular plug instead of the standard 'pc' plug
03:35 PM Tom_L: but it's the DC side you need to get right
03:40 PM roycroft: i'm not sure digikey can have connectors delivered the uk in a day
03:40 PM roycroft: certainly not affordably
03:41 PM lcnc-relay: <voiditswarranty@> aahh perhaps not. I'm in the middle of nowhere Canada, and somehow they can overnight something from a US warehouse for $10, blows my mind. everything else is +1 week and +$80
03:44 PM lcnc-relay: <voiditswarranty@> I've also gotten into the habbit of cutting the ends off of cables I throw out and saving the ends. My scrap box now is a good source of adapters for weird things. I discovered a few weeks ago that i could charge my phone off of a steam locomotive if I needed to.
03:45 PM xxcoder: lol
03:46 PM lcnc-relay: <ccatlett1984@> That is a really good idea
03:46 PM lcnc-relay: <ccatlett1984@> I need to start doing that
03:46 PM xxcoder: I wonder how small locomotive you can charge off
03:48 PM lcnc-relay: <voiditswarranty@> if it outputs at least 5w of heat energy, it'll work! (it's a peltier element and a voltage regulator)
03:49 PM lcnc-relay: <voiditswarranty@> * 15w
03:49 PM xxcoder: lol ok
03:49 PM lcnc-relay: <voiditswarranty@> I do want to make a steam powered pencil sharpener one day for the desk at work
03:50 PM xxcoder: cant directly run cutter from it?
03:50 PM lcnc-relay: <voiditswarranty@> or sterling! "brb, I need a coffee so I can sharpen a pencil"
03:51 PM xxcoder: ehh too low power
03:51 PM lcnc-relay: <voiditswarranty@> well, it's not like any of this is reasonable anyway š
03:52 PM xxcoder: indeed
03:52 PM lcnc-relay: <voiditswarranty@> +normal or
03:52 PM roycroft: what would be a nice mix of old and new technologies would be to build a steam engine to generate power to operate a laser pencil sharpener
03:52 PM lcnc-relay: <voiditswarranty@> oohh perfect
03:53 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/rue/Steam_engine/Steam_engine3.jpg
03:53 PM Tom_L: my grandfather made that for me
03:54 PM Tom_L: just need a pencil sharpener attachment
03:54 PM xxcoder: thats cool.
03:57 PM andypugh_: This would be the perfect steam pencil shapener, it requires an oscillating motion. https://www.youtube.com/shorts/4C9irbGod20
03:58 PM lcnc-relay: <voiditswarranty@> need a steam plant to power a robot arm to pick up the pencil and operate that pencil sharpener
03:58 PM Tom_L: pretty cool andy
04:00 PM andypugh_: Isnāt it? In fact I just went to eBay to see if I could find one to convert.
04:00 PM andypugh_: (I couldnāt)
04:01 PM Tom_L: led me to this though: https://www.tiktok.com/@rescuerestore/video/7397436845677727018?lang=en
04:02 PM Tom_L: various antique sharpeners
04:02 PM Tom_L: including that one
04:03 PM xxcoder: 1907 one is cool
04:18 PM xxcoder: lol very sunny here now
04:18 PM xxcoder: I guess weather here heard roy statement and wanted to take a break too
04:27 PM andypugh_: Sorry, donāt want to get political, but what is the general feeling in the US about Trumpās plan to invade Greenland and Panama. (To keep this simple, I am not asking for your individual opinions, just curious what the _general_ opinion is.
04:28 PM JT-Shop: I have no opinion on politics or religion
04:31 PM * JT-Shop ponders the accelerator cable connection on the 43 year old C3
04:41 PM Roguish: andypugh_, Trumpass is worse than a stupid idiot...
04:42 PM * JT-Shop changes channels
04:42 PM lcnc-relay: <roguish> oh, JT
04:43 PM lcnc-relay: <roguish> relax
04:45 PM andypugh_: Anyone not seen this? Spoof documentary on making the Triumph Rocket 3. https://www.youtube.com/watch?v=n0LSh97AbMw
04:57 PM bjorkintosh: that's funny as hell andypugh_
05:03 PM Roguish: andypugh_, what media in the UK do you watch and/or read for news ??? just curious
05:03 PM xxcoder: id suggest talk about politics in pm
05:03 PM Roguish: not talking politics...
05:04 PM andypugh_: Basically none. I heard about the Greenland thing through someting that popped up in the taskar of my work (windws) PC
05:04 PM Roguish: ok
05:04 PM andypugh_: And I was basically astonished.
05:04 PM bjorkintosh: andypugh_: the general feeling (in my head) is that it's just trolling for the lols.
05:05 PM Roguish: I occasionally look at The Times, and the Financial Times.
05:05 PM xxcoder: the bike video ios funny
05:06 PM Roguish: looks like London may get snow tonight.... guess that's almost now
05:07 PM andypugh_: Itās a bit of a standing joke that it only makes the news if it snows in London (and then the ācountryā grinds to a halt.
05:08 PM andypugh_: In the house where my parentls lived nobody has been able to get out withotu a 4x4 for a couple of days, but they are used to it, so just cipe.
05:08 PM xxcoder: it very rarely snows here
05:09 PM xxcoder: and most of snow reaches surface and says nope and melts
05:10 PM andypugh_: Let me try that sentence again. With actual words.
05:11 PM bjorkintosh: cope?
05:11 PM andypugh_: In the village where my parents used to live (and where I am going at the weekend) nobdoy has been able to leave without a 4x4 vehicle for a couple of days. Mainly due to ice and hills, but also due to snow. But they are used to it, and (for example) leave their cars at the bottom of the hill nearer the main road.
05:15 PM xxcoder: fun. reminds me of old grandparents house
05:16 PM xxcoder: it was bottom of pretty steep road, and its a deadend. you would have to go upwards to get out
05:16 PM xxcoder: I literally had to walk uphill in snow to go to school everyday
05:17 PM xxcoder: thnkfully not barefoot
05:17 PM xxcoder: downhill on return from school of course
05:36 PM memleak: in my experience, snow tires make a bigger difference than drivetrain layout.
05:37 PM memleak: also speed helps you from getting stuck
05:57 PM andypugh_: Itās a road where you donāt want to drive too fast.
05:58 PM andypugh_: https://maps.app.goo.gl/wJnrWRkC8aZTZMUk7
05:59 PM andypugh_: (Especially if you might meet someone coming the other way. The ditches are rather deep)
06:08 PM Tom_L: made for horse & buggy?
06:11 PM xxcoder: considering how old hold is, probably?
06:11 PM xxcoder: house
06:13 PM andypugh_: Yes. it was literally a packhorse track. There is a turn further down the hill where the packhorse track wasnāt widened and itās a narow path of large flat stones, and then cobbles where it gets steeper. Itās very quaint.
06:16 PM acer: andypugh_, I dont miss winter.
06:16 PM acer: Though it is 60f outside right now
06:16 PM acer is now known as _unreal_
06:16 PM lcnc-relay: <big_kevin420@> -10c right now,
06:17 PM lcnc-relay: <big_kevin420@> good news is, the spindle doesnt get so hot
06:17 PM _unreal_: :X
06:17 PM lcnc-relay: <big_kevin420@> now, i warm my hands on the spindle
06:17 PM _unreal_: You know its interesting my new water cooled spindle does not get HOT at all I have yet to get it to even get much more then slightly warm
06:17 PM xxcoder: do a hard cut on inocel so red hot chips heat your shop
06:18 PM _unreal_: My 300 watt on my small cnc. THAT thing gets hot
06:21 PM lcnc-relay: <big_kevin420@> the panama/greenland stuff is all talk, but this canada shit, is gonna nail us. the general feeling is very bad
06:50 PM lcnc-relay: <skunkworks8841@> I think I am just going to stop watching any news for the next 4 years.
06:50 PM bjorkintosh: I stopped watching the news ... a very long time ago.
06:51 PM lcnc-relay: <skunkworks8841@> when I see the nuclear bomb flashes - I know the shit must have hit the fan...
06:51 PM bjorkintosh: I figured, if The Man wants to get a hold of me, it'll send someone.
06:51 PM bjorkintosh: The Man would not expect me to be glued to the radio or tv in order to hear from it.
06:52 PM bjorkintosh: the only problem is, everyone else watches the news and won't stop telling me about it.
06:53 PM lcnc-relay: <skunkworks8841@> andypugh@ I am finding out I need British parallel pipe thread... lol..
06:53 PM lcnc-relay: <skunkworks8841@> same
06:53 PM Tom_L: certain few keep bringing it up
06:54 PM Tom_L: skunkworks, time for single point
06:57 PM lcnc-relay: <skunkworks8841@> lol - hydraulic fittings. I buy them off amazon or ebay š
06:58 PM lcnc-relay: <skunkworks8841@> it just took a bit to figure out what the hell I needed
06:58 PM lcnc-relay: <skunkworks8841@> cyoties are yipping outside tonight
06:59 PM lcnc-relay: <skunkworks8841@> coyote..
06:59 PM lcnc-relay: <skunkworks8841@> that is a wierdly spelled word
06:59 PM bjorkintosh: it is not english.
07:00 PM bjorkintosh: that is why the orthography appears odd
07:03 PM lcnc-relay: <andypugh@> British Parallel Pipe Thread is actually the ISO metric standard, so significantly more common globally than the US standard.
07:05 PM andypugh_: Which is why this āmetricā thread has a 1/4 size that is 13.157mm OD. (itās not a round number in inches either)
07:05 PM andypugh_: https://en.wikipedia.org/wiki/British_Standard_Pipe
07:06 PM andypugh_: Ooops. wrong chat
07:06 PM xxcoder: nah it works from both sides so whatever lol
07:06 PM lcnc-relay: <andypugh@> So it does.
07:11 PM lcnc-relay: <skunkworks8841@> I got some knockoff spool valves that all seem to use bspp.. Sometimes i think they are G?
07:11 PM lcnc-relay: <skunkworks8841@> they are face sealing which was the hardest part
07:11 PM lcnc-relay: <skunkworks8841@> Now that I know the terms - I seem to find what I need
07:15 PM lcnc-relay: <skunkworks8841@> https://photos.app.goo.gl/XcdZ6ZQyQxaU51ZN7
07:19 PM lcnc-relay: <skunkworks8841@> it has been a long time since I have done hydraulic work
07:23 PM lcnc-relay: <skunkworks8841@> but it seems to be like riding a bike..
07:28 PM _unreal_: THAT any one from party can agree on!!! "<bjorkintosh> I stopped watching the news ... a very long time ago."
07:29 PM _unreal_: Tom_L, if your dbl fisting, does that still count as a single pint..... cough per hand? cough
07:31 PM _unreal_: andypugh_, for us in the USA especially me. considering I work on luxury yachts, British thread is my VAIN!!!!!
07:33 PM lcnc-relay: <big_kevin420@> hmm anyone know if there a twopass option for the INI file?
07:36 PM Tom_L: TWOPASS=ON - Use two pass processing for loading HAL comps. With TWOPASS processing, all [HAL]HALFILES are first read and multiple appearances of loadrt directives for each moduleb are accumulated. No hal commands are executed in this initial pass
07:37 PM Tom_L: http://linuxcnc.org/docs/stable/html/config/ini-config.html
07:37 PM lcnc-relay: <big_kevin420@> for the ini
07:37 PM lcnc-relay: <big_kevin420@> so if i have duplicate [SECTION] it would like, twopass read it and combine it
07:37 PM Tom_L: not that i'm aware of
07:37 PM Tom_L: don't duplicate a section?
07:38 PM lcnc-relay: <big_kevin420@> its for using #INCLUDE files
07:39 PM Tom_L: call them [SECTION] and [SECTION1] ?
07:39 PM lcnc-relay: <big_kevin420@> which are nice, but they basically just mash all the files together to make 1 ini file
07:39 PM lcnc-relay: <big_kevin420@> its for RS274
07:40 PM lcnc-relay: <big_kevin420@> and [DISPLAY]
07:40 PM Tom_L: postgui?
07:40 PM Tom_L: still hal...
07:40 PM lcnc-relay: <big_kevin420@> trying to make it easy to add probe/toolsetters to configs
07:41 PM lcnc-relay: <big_kevin420@> https://github.com/cakeslob/RRW_LAB/blob/inc/LinuxCNC/ConfigSamples/remora-RRW_LAB_inc/remora_main.ini
07:42 PM lcnc-relay: <big_kevin420@> it appears to not like when theres 2 [SECTIONS] even if they dont dupl;icate parameters
07:42 PM lcnc-relay: <big_kevin420@> well, not that it doesnt like uit, i dont think anything is happening
07:44 PM lcnc-relay: <big_kevin420@> it doesnt complain though
07:44 PM Tom_L: it may just ignore one
07:44 PM lcnc-relay: <big_kevin420@> yeah it seems to ignore the second one
07:45 PM lcnc-relay: <big_kevin420@> not duplicate parameters, but dup [SECTION]
07:45 PM Tom_L: jup
07:46 PM Tom_L: do your parameters have to be in a certain section?
07:46 PM lcnc-relay: <big_kevin420@> the idea was, you have your config aalready, and you wanna add a probe
07:47 PM lcnc-relay: <big_kevin420@> so you just put in the .inc and .hal file
07:47 PM lcnc-relay: <big_kevin420@> and ad #INCLUDE probe.inc and it will have the parameters you need
07:48 PM lcnc-relay: <big_kevin420@> so you may have 2 [DISPLAY] sections, but not confl;icting parameters
07:48 PM lcnc-relay: <big_kevin420@> but that doesnt seem to be the case on how it works
09:22 PM memleak: hey waddap rdtsc
09:22 PM memleak: snaked, good to see you again :)
09:23 PM snaked: Glad to be memorable.
09:23 PM memleak: your trim package is too :P
09:24 PM snaked: Don't tease.
09:26 PM memleak: :/ sorry
09:27 PM memleak: i just thought your comment a few weeks ago was gold
09:27 PM snaked: I'm both not offended and also chiefly driven by nonsense :P
09:27 PM memleak: ahhh
09:49 PM rdtsc: Had my head buried in youtube, heh. "Better to be seen than viewed." ;)
09:51 PM memleak: I was as well, really enjoyed watching the torture test between the F-150 and Cybertruck.
09:52 PM memleak: dude just absolutely destroyed both
09:53 PM memleak: reminded me of the episode of top gear where they take a hilux, drown it in the ocean, and blow up a giant building from under it, and it still ran
09:53 PM xxcoder: is tht where they found out that cybertruck frame is alum?
09:54 PM memleak: my father owns a land cruiser with _probably_ over 400K miles on it. i say probably because the odometer stopped working awhile ago xD
09:55 PM memleak: toyota certainly knows how to build decent trucks
09:55 PM memleak: xxcoder, not sure. i only watched part 2
09:55 PM xxcoder: lol ok
09:58 PM memleak: personally I'd like a tundra pick-up with the biggest engine it comes in
10:11 PM lcnc-relay: <thorhian@> Can anyone point me in the direction to find a motor that can be powered via 110V (probably 800W) that can get up to 6000 RPM while still being controlled by LCNC? Iāve been seeing some BLDC motors that can do 6000 RPM in that power range, but they seem to have janky and no IO for automated control.
10:13 PM lcnc-relay: <thorhian@> I was thinking of getting one of those cheap collet spindles and use it as a motor, but they run really fast. My spindleās supposed max speed is 8000 RPM, so Iād have to gear it down by like 2~4 times depending on the motor.
10:29 PM lcnc-relay: <captainhindsight_.@> Many servos fit this
10:30 PM lcnc-relay: <captainhindsight_.@> Thorian: step/fit , ethercat or what for control?
10:30 PM lcnc-relay: <captainhindsight_.@> Hehe step/dir
10:35 PM lcnc-relay: <captainhindsight_.@> https://www.automationtechnologiesinc.com/products-page/servo-products/dmm-dyn4-servo-kit-750w-w-nema-34-frame
10:35 PM lcnc-relay: <thorhian@> Well my big 1.8kw servo is driven with 0-10V. I canāt use it anymore though since I donāt live in a place that allows me to use 220V. I have a 7c81 and a 7i76.
10:36 PM lcnc-relay: <captainhindsight_.@> Search around here^^^
10:37 PM lcnc-relay: <thorhian@> Well it looks good, but itās probably well outside my price range unfortunately.
10:37 PM lcnc-relay: <captainhindsight_.@> Older servos and drives were analog and you can find lots of eBay if you can use used
10:38 PM lcnc-relay: <thorhian@> Yeah my 1.8Kw servo was around ~$300, but itās older tech from China.
10:40 PM mrec: andypugh_: do you have any idea how much power should the A axis have for gear hobbing? It should be almost none no?
10:41 PM mrec: I wonder how much can gear hobbing align itself
10:42 PM lcnc-relay: <captainhindsight_.@> Thorian: if you spend the time on eBay you might find a deal from someone that is stuck with some and don't know what they have
10:42 PM lcnc-relay: <captainhindsight_.@> Or have a typo in the listing
10:45 PM lcnc-relay: <thorhian@> If this had some IO, Iād be tempted to buy it. https://a.co/d/hhpxjbB

10:53 PM lcnc-relay: <captainhindsight_.@> Crap fanuc from the 90's with a windows GUI from the 00's
11:02 PM lcnc-relay: <captainhindsight_.@> https://photos.app.goo.gl/BrqbwRC9a7CUY1rE9
11:03 PM lcnc-relay: <captainhindsight_.@> The GUI for the remote guided vehicles (rgv)
11:03 PM lcnc-relay: <captainhindsight_.@> These go down about every 2 hours
11:06 PM lcnc-relay: <captainhindsight_.@> But they only want them repaired with genuine fanuc and jtekt parts, so they never work properly
11:36 PM mrec: what is that? kind of pallet changer?
