12:19 AM lcnc-relay: <vibram> This is what I read indeed.
12:31 AM lcnc-relay: More on my issue. Blinking green led when I do nothing.
12:31 AM lcnc-relay: As soon as I set output 00 in Hal show, no green led and get the red led. So indeed I must have a wiring issue
12:31 AM lcnc-relay: <vibram> The issue maybe come from here sserial_port_0=1xxxxxxx
12:31 AM lcnc-relay: I set to 2xxxxxx but I must have lost changes
01:12 AM Deejay: moin
04:08 AM -!- #linuxcnc mode set to +v by ChanServ
04:33 AM Tom_L: morning
04:33 AM lcnc-relay: <travis_farmer> Morning
04:34 AM lcnc-relay: <travis_farmer> vibram , carefull, not all the pins on that board are 5v, some are 3.3v
04:41 AM lcnc-relay: <vibram> OK, i hope i didnt burst something
04:41 AM lcnc-relay: <vibram> What is really strange to me is I'm able to see the card in halshow so it's correctly recognized but when I try to send a command it doesn't work
04:41 AM lcnc-relay: <vibram> maybe one wire is wrong
04:42 AM JT-Cave: morning
05:44 AM -!- #linuxcnc mode set to +v by ChanServ
05:57 AM * JT-Cave goes to load up the road bike
06:01 AM -!- #linuxcnc mode set to +v by ChanServ
06:09 AM -!- #linuxcnc mode set to +v by ChanServ
08:08 AM lcnc-relay: <vibram> By default on the 7i73, W5, W6 and W7 are set à UP or down when they have the jumper ?
08:16 AM rdtsc2: Vibram, check the manual: http://www.mesanet.com/pdf/parallel/7i73man.pdf
08:19 AM lcnc-relay: <vibram> I did but I didn't find where it was clearly mentionned if the jumper is here is order to set Up or down
08:20 AM lcnc-relay: <vibram> https://jauriarts.org/_matrix/media/v3/download/jauriarts.org/AKOrpyoOSbKuceIIkJXJTyyl/image.png
08:20 AM lcnc-relay: <vibram> like this is down I should understand?
08:21 AM lcnc-relay: <vibram> OK i think i understood, was not crystal clear with my english level
08:35 AM rdtsc2: I think Peter (creator of Mesa cards) is a whole other breed of human, perhaps super-human. The rest of us can only try to understand. :)
08:41 AM lcnc-relay: <travis_farmer> page 8 of the manual describes if they should be up or down. some up, some down, depending on what mode you want
08:42 AM lcnc-relay: <travis_farmer> are you going to have a keypad, or just inputs and outputs?
08:43 AM lcnc-relay: <travis_farmer> by keypad, i mean a matrix keypad
08:43 AM lcnc-relay: <travis_farmer> vibram ^^
08:48 AM lcnc-relay: <travis_farmer> the default is down, as shown, for no keypad, and no LCD
09:19 AM * JT-Cave did 13 miles again today
09:20 AM JT-Cave: https://pasteboard.co/xUvya7SGPV6x.png
09:20 AM lcnc-relay: <roguish> JT-Cave: good going
09:24 AM JT-Cave: not hitting any limits except time
09:24 AM JT-Cave: 5 uphills and 5 down
09:25 AM lcnc-relay: <roguish> most important is you just get out and go.....easy is cool
09:25 AM lcnc-relay: <roguish> I rode a total of 65 miles on Fri and Sat. pretty tired, but not totally pasted.
09:30 AM lcnc-relay: <travis_farmer> i have been so tied up trying to sell this dang truck, i have not been out much... 😦 can't wait for it to sell so i can get out and ride more... say nothing about building my workshop!
09:31 AM lcnc-relay: <vibram> yup thank you very much, this is what i understood finally
09:31 AM lcnc-relay: <vibram> so i need to investigate my wire
09:34 AM lcnc-relay: <roguish> forecast is mid 90's today......
09:35 AM lcnc-relay: <travis_farmer> low 70's here
09:36 AM JT-Shop: nice mornings here 60 at sunrise
09:36 AM lcnc-relay: <travis_farmer> looks like rain, except thursday and this weekend
09:37 AM lcnc-relay: <travis_farmer> yeah, i gotta get out at sunrise, but i keep sleeping in 😉
09:37 AM lcnc-relay: <roguish> ooo. Raspberry Pi just went public on the London market
09:52 AM JT-Shop: roguish is there any kind of wear indicator on road tires?
09:53 AM lcnc-relay: <roguish> JT-Shop: not that i've seen.....
09:53 AM JT-Shop: ok, just wondering... a blowout at 20 mph would hurt
09:53 AM lcnc-relay: <travis_farmer> especialy on front
09:55 AM lcnc-relay: <roguish> JT-Shop: oh yeah. I keep a pretty close watch on the tires. the wear depends on the pressure, the surface, and the load...... of course.
09:56 AM lcnc-relay: <roguish> i use Continental tires, almost exclusively. just like them. the mid priced ones. not cheap, and not most expensive. also 'foldable' which means non-wire bead.
09:58 AM lcnc-relay: <roguish> I've heard of people blowing out the front and going down hard. definitely not fun.
09:59 AM lcnc-relay: <travis_farmer> i blew out the front on an off-road downhill turn... i didn't go down, but i was a bit scared 😉
09:59 AM lcnc-relay: <roguish> but I think a full blowout is rear. i usually get slow leaks, and feel them before they're too low.
10:00 AM lcnc-relay: <travis_farmer> mine was a pinch-plat
10:02 AM lcnc-relay: <roguish> the last blowout i had was a drywall screw straight in, with it's tip actually sticking out one of the spoke holes......it pinned the tire r down tight on the rim.... pretty funny.
10:03 AM lcnc-relay: <roguish> here's one of my best buddies
10:03 AM lcnc-relay: <roguish> https://jauriarts.org/_matrix/media/v3/download/matrix.org/kDplLgreQXnJwVrGXUsHrYGW/20210731_092941.jpg
10:03 AM JT-Shop: I have giant made in tiawan tires on there now
10:04 AM lcnc-relay: <roguish> look closely at his right leg. it's a peg.
10:04 AM lcnc-relay: <roguish> below the knee amputee. hit by a car, leg caught up in the wheel well, and munched.
10:05 AM JT-Shop: ouch
10:05 AM lcnc-relay: <travis_farmer> dang, that had to hurt
10:05 AM JT-Shop: hmm continental has 12 choices for tires lol
10:05 AM lcnc-relay: <roguish> been to the ParaOlymipics twice riding on the track. gold medal.
10:05 AM * JT-Shop does a little work... very little
10:05 AM lcnc-relay: <roguish> JT-Shop: the Gatorskins are pretty good.
10:06 AM lcnc-relay: <roguish> they'll last a long, long time.
10:06 AM lcnc-relay: <roguish> I don't get too cheap with tires or brake pads....
10:07 AM lcnc-relay: <roguish> and I'm told I squeak when i walk....
10:07 AM lcnc-relay: <travis_farmer> what, no Michelins? 😉
10:08 AM lcnc-relay: <roguish> just don't care for Michelins....
10:08 AM lcnc-relay: <travis_farmer> yeah, they don't make a great MTB tire either
10:10 AM lcnc-relay: <travis_farmer> i have heard Pirelli Scorpions are the best MTB tire, but i like Maxxis
10:12 AM lcnc-relay: <roguish> JT-Shop: there was a group riding along one of the popular streets, with a wide bike lane. 2 abreast like normal. a lady driving along in a big old car heard voices from Satan that told her to drive into the group. killed on cyclist, my friend got messed up, in coma for 7 days and leg amputated. couple of others rolled off the hood....... true story
10:12 AM lcnc-relay: <travis_farmer> this seems t have turned into the bike channel 😉
10:13 AM lcnc-relay: <roguish> the crazy lady is still in the mad pad, almost 30 years later...
10:13 AM lcnc-relay: <travis_farmer> should be
10:45 AM lcnc-relay: <roguish> ok, time to ride, before it heat up too much. chiao. bbl
10:56 AM roycroft: hunter biden was just found guilty on all charges - charges that are not prosecuted in the overwhelming majority of cases, especialy involving alleged first-time offenders
10:57 AM roycroft: so aha! we have proof that the justice departiment has become weaponized against conservatives!
10:57 AM roycroft: oh, wait ....
10:57 AM roycroft: :)
10:59 AM CaptHindsight: years ago that would be funny, but since stupid has been raised to a new art form hardly anyone will get the joke today
11:13 AM roycroft: i suppose we're too polarized for nuance and humor to enter our minds these days
11:13 AM * roycroft focuses on debugging a vpn issue, which, while the problem makes no sense, makes more sense than the conversation here :)
11:18 AM CaptHindsight: it's a touchy subject ..... if you ever work with people who have disorders such as anorexia or schizophrenia it becomes clear what is going on at a worldwide level
11:19 AM CaptHindsight: we just reclassify it since it might work against political and ideological agendas
11:35 AM rdtsc2: The driving agendas around these parts seem to be "as fast as possible, at all times." 70 in a 55 construction zone is still not fast enough
11:36 AM rdtsc2: No cops = wild wild west
11:37 AM CaptHindsight: I tend to move out of their way and then look for them overturned down the road. Happens too often.
11:40 AM CaptHindsight: it's all part of the "you don't tell me what to do, I tell you what to do"
11:40 AM lcnc-relay: <skunkworks8841> we think we had a computer here that was taking a switch out.. (causing other computers to disconnect..) I don't know if I have ever seen that..
11:41 AM CaptHindsight: skunkworks8841: maybe an exploit, I've seen some take out switches
11:42 AM CaptHindsight: plug in the infected PC to the network and the switch starts to blink on all ports at the same time, ~1 sec. intervals
11:42 AM lcnc-relay: <skunkworks8841> my guy said it was stuck at a windows update.. He rebooted it and the other computer re-connected to the network.
11:44 AM CaptHindsight: I lost a switch or two maybe 10 years ago when someone on my network thought it was OK to try and have discussions with troublemakers on IRC
11:49 AM lcnc-relay: <skunkworks8841> Lol - I couldn't remember the password I set to get into the managed switches (the switch that failed was just a cheap unmanaged one)
11:50 AM lcnc-relay: <skunkworks8841> Finally remember the one switch I was trying to get into - I had accidently had the caps lock on when I entered the password..
11:51 AM lcnc-relay: <skunkworks8841> at the time I probably though - I will remember that.. (well - I guess I did - but only after panicing a little bit)
12:17 PM rdtsc2: Found an old gigabit switch on eBay for cheap... man that thing was not easy to configure. Must use Windows XP to do the lan-configure thing, and serial managment might as well be a whole other language. After the initial headache of setup, been running for years though.
12:20 PM rdtsc2: Takes like 5 minutes to fully boot-up. Surprised there isn't a coal slot on it somewhere.
12:41 PM roycroft: i still use cisco switches/vpn concentrators/routers exclusively, except for my wi-fi stuff
12:42 PM roycroft: they are cheap (older ones), they work forever, and i've been working with them since the '80s
12:42 PM roycroft: so i can do most things in my sleep
12:47 PM lcnc-relay: <skunkworks8841> I have been using mikrotik.. (we swiched mostly to them after converting some main trunk lines to fiber.)
12:48 PM lcnc-relay: <skunkworks8841> they seem ok - but my luck I bought 2 that had some major firmware/hardware issues. It took them forever to figure out.
12:50 PM lcnc-relay: <skunkworks8841> they have switchos and routeros - switchos is pretty basic while routeros has a lot more bells and whisltes. for our internal network - we really only need switchos.
12:50 PM lcnc-relay: <skunkworks8841> most of thier hardware runs both os's
12:51 PM lcnc-relay: <skunkworks8841> (except for the one that had issues - it only was able to use routeros. When they finally got switchos working on it - it solved my issues.
12:51 PM Unterhaus_ is now known as unterhausen
12:52 PM unterhausen: I asked gemini to make me a picture of a linuxcnc user, and it won't make pictures of people anymore
12:54 PM * roycroft is struggling with a l2l vpn issue today, unfortunately
01:01 PM lcnc-relay: <redeye_joe> it this a good place to ask about plasma cnc? I am wanting to use my snapon plasma50 for a diy cnc I made, and need help with electronics.
01:03 PM CaptHindsight: just ask away
01:05 PM CaptHindsight: redeye_joe ^^
01:05 PM roycroft: ok, vpn tunnel fixed
01:05 PM roycroft: yay
01:05 PM * roycroft does not have to drive 50 miles each way to reset a device now
01:08 PM CaptHindsight: or crawl through a tunnel
01:09 PM lcnc-relay: <redeye_joe> from what I am understanding, I will need a voltage divider, to be able to read a pin on controller to see that arc is on, and also be able to control the on/off trigger?
01:09 PM lcnc-relay: <redeye_joe> +to
01:12 PM CaptHindsight: redeye_joe : what electrical hardware are you using?
01:13 PM CaptHindsight: is there some guide you have seen for the snapon plasma50?
01:15 PM CaptHindsight: is there an "Arc On" signal in there?
01:15 PM lcnc-relay: <redeye_joe> no, I havent been able to find any guide on how to connect to any old plasma, only one guy who bought a cnc ready plasma cutter and used mesa thc300 torch height controller
01:16 PM lcnc-relay: <redeye_joe> I am not sure, I figured, it could be read directly from the ground cable(think it is the positive on plasma's)
01:17 PM CaptHindsight: http://store.mesanet.com/index.php?route=product/product&product_id=128
01:18 PM CaptHindsight: http://www.mesanet.com/pdf/analog/thcadman.pdf
01:19 PM lcnc-relay: <redeye_joe> yes, I saw that board, and figured it would work. I sent them a email, but I figured this would be a good place to ask. Does that board only work with one of their controllers?
01:19 PM CaptHindsight: what is your controller plan?
01:22 PM lcnc-relay: <redeye_joe> i have one of the cheap parellel control boards, I was thinking of using,
01:24 PM CaptHindsight: triggers are controlled easy enough with a relay, ARC OK signal have to be detected and how is done varies by the model of the plasma cutter
01:24 PM lcnc-relay: <redeye_joe> the cnc now is running off a marlin board, with tmc drivers, but I am thinking i will need to use linuxcnc to run it as a plasma.
01:26 PM lcnc-relay: <skunkworks8841> the mesa board is a voltage to frequency converter. It can be read by a printer port. (but getting something better would be my opinion)
01:27 PM CaptHindsight: the big question is how do you get an ARC OK signal from your plasma cutter?
01:27 PM lcnc-relay: <skunkworks8841> without blowing out your low voltage electronics..
01:27 PM CaptHindsight: how did you do it with the marlin board?
01:30 PM CaptHindsight: for motion control you have many options
01:31 PM lcnc-relay: <redeye_joe> ?? maybe this?https://cnc4pc.com/plasma-voltage-divider.html
01:32 PM CaptHindsight: and yes you might need a voltage divider to shift the level of the ARC OK signal to the required input levels of electronic hardware and possible more like isolation
01:33 PM lcnc-relay: <redeye_joe> marlin board i used just for router cutting, with aspire vcarve, and I am planning on using fusion for my workflow for plasma
01:33 PM CaptHindsight: https://ohmslawcalculator.com/voltage-divider-calculator ohms law
01:35 PM lcnc-relay: <redeye_joe> I was really hoping to be able to ride someone else's project or guide as I dont know much about plasma electronics...
01:37 PM lcnc-relay: <redeye_joe> from what I have read on guide for mesa thcad board, I need to figure out if my plasma is a touch start or not, and then I can see which board and voltages I will need.
01:38 PM CaptHindsight: touch vs trigger
01:38 PM CaptHindsight: that is important since you need to know how to start the arc
01:39 PM lcnc-relay: <redeye_joe> maybe, not sure, I think it has to do with if you need to touch to start the arc or if it is a non touch start cutter machine, I think both touch and non touch have a trigger still
01:39 PM CaptHindsight: trigger may be started with a relay in parallel with the trigger switch
01:40 PM CaptHindsight: touch will require the replication of the touch motion
01:40 PM lcnc-relay: <redeye_joe> yeah, trigger part I figured would be fairly simple, and my machine like I think all of them have that wired to the front. so taping into it would be fairly simple...
01:41 PM CaptHindsight: the touch trigger is more of an "allow arc to start" signal
01:41 PM CaptHindsight: the arc starts by touching the material with the tip
01:41 PM lcnc-relay: <redeye_joe> yeah, or just the torch fire height might need to be closer to the surface, so it can arc, I dont think it need to actually touch.
01:42 PM CaptHindsight: but that doesn't guarantee that an arc has started and is still running
01:43 PM CaptHindsight: http://linuxcnc.org/docs/html/plasma/plasma-cnc-primer.html
01:44 PM lcnc-relay: <redeye_joe> thank you, that seems to be the info I needed. sounds like I might need to buy a cnc ready nontouch
01:44 PM CaptHindsight: it will make your job easier
01:48 PM lcnc-relay: <redeye_joe> I knew this coming into this an most of my projects,,, but my budget always makes me do it the hard way,,, 🙂
01:51 PM CaptHindsight: or spend some more time reading and asking questions
01:52 PM CaptHindsight: scour the LCNC forums for similar projects
01:52 PM CaptHindsight: https://forum.linuxcnc.org/
01:52 PM CaptHindsight: heh I see that you already posted there
01:53 PM lcnc-relay: <redeye_joe> yes, I posted a question on their too,
01:53 PM CaptHindsight: just today so wait a couple days
01:53 PM lcnc-relay: <redeye_joe> 🙂 the good part about the hard way is you learn alot.. which seems to apply for me later on the next projects..
01:54 PM lcnc-relay: <redeye_joe> yeah, I figured someone might have already done something simular and might be able to help.
02:16 PM rdtsc2: Those that have done it, are likely busy cutting out parts and making fantastic things.
02:26 PM roycroft: i got some basil starts planted at lunch time today - that makes it really feel more like home now
02:40 PM CaptHindsight: planting actual roots
02:44 PM CaptHindsight: which is more useful to the average hobby machinist, Sinker EDM, Wire EDM, Electroforming 3D Printer, CNC plasma cutter or sand mold printer for aluminum casting?
02:44 PM CaptHindsight: hobby machinist/maker
02:46 PM roycroft: yes, literally and figuratively
02:46 PM roycroft: (and i know the difference :)
02:51 PM lcnc-relay: <travis_farmer> <-- is very depressed that his truck isn't selling...
02:58 PM roycroft: i've found that those things tend to take more time than they used to in the post-pandemic economy, travis_farmer
02:58 PM roycroft: i personally have a lot of stuff to sell, including multiple vehicles, and i'm trying to set realistic expectatins
02:59 PM roycroft: as in budgeting for the cost of a storage unit for a year
02:59 PM roycroft: i'm still working on that
02:59 PM roycroft: the question is: do i spend the money on the storage unit, or do i get rid of everything a fire sale prices?
02:59 PM roycroft: so far, the storage unit seems a better idea
03:00 PM CaptHindsight: I have found that having suggestions for how the vehicle or tool may be use often helps....
03:00 PM roycroft: i think i'll recoup way more than the cost of the unit if i can sell at reasonable prices instead of fire sale prices
03:00 PM lcnc-relay: <travis_farmer> i lowered the price on my truck by $200, and still not one good call on it
03:00 PM roycroft: well two of my vehicle are vw buses
03:00 PM roycroft: all i have to do is advertise nationally and say "west cost - not rust buckets"
03:01 PM CaptHindsight: took a single day to sell 3-phase lathes or mills by adding "easily converted for use with home garage wiring"
03:01 PM roycroft: each of them should bring $6k-$8k or more if i wait for the right person
03:01 PM roycroft: or i can sell them locally for $1.5k-$3k
03:01 PM CaptHindsight: or "good car for winter snow"
03:02 PM roycroft: my lathe is the machine i'm most concerned about
03:02 PM roycroft: i don't think it will fit in my new shop until i build the extension, which won't happen until next summer
03:02 PM lcnc-relay: <travis_farmer> how could i better sell this? https://www.unclehenrys.com/classified/5007191/classified
03:02 PM roycroft: and i don't want to pay for storage for a year
03:02 PM xxcoder: wonder if you can build a mini house for it
03:03 PM xxcoder: heavily wax everything for storage in mini "lathe house" till ready
03:03 PM roycroft: maybe i'll get one of those portable garages, with the fiberglass tarp walls/roof, and just goop a couple gallons of way oil on it
03:03 PM CaptHindsight: i list no negatives unless they might be positives
03:03 PM roycroft: i looked at renting a pod
03:03 PM roycroft: those things are way too expensive
03:04 PM xxcoder: i guess best traits is protection from rain, protection from grass the metal killer, and keep humidity controlled somehow
03:04 PM roycroft: i'm still pondering purchasing a 20' cargo container and parking it in front of my shop
03:04 PM roycroft: rain and foliage protection is easy
03:04 PM roycroft: humidity very difficult
03:04 PM CaptHindsight: seal it in a bag with dessicant
03:05 PM CaptHindsight: https://usautosupplies.net/collections/plastic-bag-covers-auto-body
03:05 PM xxcoder: well travis it looks reasonable listing. I have no idea on pricing good or not but besides that yah
03:06 PM CaptHindsight: https://www.calcarcover.com/product/evp-extreme-vehicle-protection-360-degree-car-storage-bag/4373
03:07 PM lcnc-relay: <travis_farmer> it KBBs for $7600
03:10 PM xxcoder: used vehicles market crushed recently I think
03:10 PM xxcoder: demend was nuts few years ago but now dunno
03:10 PM roycroft: if i can get a 20' container delivered for $5k that might be my best option
03:10 PM xxcoder: 5k is a lot but its one time, besides from repair and sealing it
03:11 PM lcnc-relay: <travis_farmer> well, the local school just graduated... i am thinking grad present for a new worker 😉
03:17 PM roycroft: the high schools around here all had graduation last weekend
03:52 PM Tom_L: busy day here i see
04:07 PM CaptHindsight: https://chicago.craigslist.org/chc/fod/d/chicago-shipping-container-shipping/7755728667.html
04:07 PM xxcoder: those is so common, I guess 5k usd is because it includes shipping
04:08 PM xxcoder: actually surpising cheap. 2140 usd to my zipcode for used 20 ft standard
04:09 PM xxcoder: (shipped)
04:09 PM xxcoder: 3290 for new
04:09 PM CaptHindsight: used are really a gamble, no yah can't see the container first
04:10 PM xxcoder: I bet. new is just a thousand or so more so yeah not too bad
04:10 PM xxcoder: 4790 for high 40 ft shipped
04:11 PM xxcoder: usd
04:11 PM xxcoder: that site defines used as have small dents and straches but are still airtight and watertight
04:12 PM xxcoder: doors must be still working, and has handles still
04:12 PM xxcoder: seems reasonable
04:12 PM CaptHindsight: huh, prices in NW look higher than the midwest
04:13 PM xxcoder: https://www.youtube.com/watch?v=nPsi0hQlAq4
04:14 PM CaptHindsight: https://eugene.craigslist.org/grq/d/newberry-springs-liquidating-interior/7746368821.html
04:15 PM lcnc-relay: <roguish> CaptHindsight: those were meant to grow pot
04:15 PM CaptHindsight: Store-n-Grow
04:23 PM roycroft: there are lots of "used one trip" containers
04:23 PM roycroft: a lot safer bet, i should think
04:25 PM xxcoder: roy honestly that site discription of used definition for them is very workable
04:25 PM xxcoder: cargo box requirements like airtight is still met
04:35 PM rdtsc2: Matt on Diesel Creek is always buying them from auction houses
04:36 PM roycroft: yeah, the folks i've emailed to guarantee their used containers are weathertight
04:42 PM roycroft: $3k delivered used, and $3.9k delivered new
04:42 PM roycroft: that might actually work for me for now
04:42 PM xxcoder: nice
04:42 PM xxcoder: year long, its cheaper than rent storage
04:42 PM roycroft: an 8x10 storage unit would cost me about $150/month
04:42 PM roycroft: the container is two of those, and right at my house
04:43 PM roycroft: so roi is 10 minths
04:43 PM roycroft: months
04:43 PM xxcoder: its long rather than wide so it'd be annoying if you need something in back but yeah
04:43 PM xxcoder: and it wont go poof once youre done too. you can still use it
04:43 PM roycroft: not too bad
04:43 PM roycroft: and a machine shop does not need a lot of width - it needs length
04:44 PM lcnc-relay: <roguish> and when you don't need it anylonger, you can rent it out as an ADU
04:44 PM roycroft: so i could put the mill and lathe and welding gear in the container
04:44 PM xxcoder: adu?
04:44 PM roycroft: and the woodworking stuff in the shop building, which is wider
04:44 PM lcnc-relay: <roguish> xxcoder: accessory dwelling unit
04:45 PM xxcoder: ahh nteresting
04:49 PM lcnc-relay: <roguish> oh joy, up to 97.3 now
04:50 PM CaptHindsight: f or C ? :)
04:50 PM CaptHindsight: humidity bothers me more now
04:51 PM lcnc-relay: <roguish> American F
04:51 PM lcnc-relay: <roguish> 52% humidity
04:51 PM rigid: how do you guys & gals protect your ball screws and linear bearing moving parts stuff from dust & chaff?
04:53 PM rigid: There seem to be multiple ways but most videos I saw, seem to use nothing. Is there a go-to solution at industrial grade machines?
04:53 PM CaptHindsight: using covers
04:55 PM rigid: what kind of covers? i could imagine rubber gaskets, brushes and a few other things but I'm not sure what nowadays professional gear uses
04:55 PM lcnc-relay: <roguish> covers if you can. some linear bearings can have seal type scrapers added
04:55 PM CaptHindsight: https://youtu.be/iX00YX6wYsE?si=ZXhXeQ-cXMaOOYtb&t=424 easy to see but metal
04:55 PM rigid: i mean, you got moving parts that are in the way.
04:56 PM CaptHindsight: https://youtu.be/4dWxWPBxZcE?si=mKxbj44ENPknEYHn&t=94
04:56 PM rigid: CaptHindsight: ah, nice! thank you
04:56 PM CaptHindsight: https://youtu.be/HKuytv1XYKo?si=UBP799BFFmmAIa2h
04:56 PM rigid: never saw those
04:57 PM rigid: hm, they seem to have the problem that they reduce travel path
04:58 PM CaptHindsight: do a search for way or ballscrew covers
04:58 PM rigid: like bellows, you can't use the whole travel path since they need some space
04:59 PM rigid: Telescopic covers seem to suffer from the same problem as bellow covers. Brushes don't have that issues but they are a pain to clean.
05:00 PM CaptHindsight: best when planned out when the machine is designed
05:02 PM rigid: yeah, and bellows use very little space. But generally with a desktop 3018, you're a bit limited :)
05:03 PM rigid: i wondered if there's maybe some one-fits-all magic I never heard of
05:11 PM rigid: i guess i'll try brushes
05:13 PM Tom_L: rigid, i used sheet neoprene
05:14 PM rigid: Tom_L: hm, how? overlapping along the axis?
05:14 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/chip_guards/Chip_guard4.jpg
05:15 PM rigid: ahw, port 81 :-/
05:15 PM Tom_L: made some bearing rollers under the corner so it was smooth
05:15 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/Bearing_Bracket/Bearing_Bracket5.jpg
05:16 PM JT-Shop: my VMC is similar but uses alum bits with rubber joints
05:16 PM Tom_L: there's a large elevator supply here. i got the neoprene free as cutoff scrap from them
05:17 PM Tom_L: as in grain elevator
05:17 PM rigid: Tom_L: you should really consider using port 433 ... any network worth their salt is blocking HOSTS2 name servers
05:18 PM rigid: *443
05:19 PM Tom_L: it's rarely been an issue for me
05:20 PM Tom_L: my isp blocks 80
05:21 PM rigid: bastards. do they also block https? (443)
05:21 PM Tom_L: i dunno
05:21 PM rigid: http is to die anyway since letsencrypt did their thing
05:21 PM rigid: "die" (in the sense of internet death, i.e. never)
05:22 PM Tom_L: i wonder if tinyurl would let you see it
05:22 PM Tom_L: probably not
05:22 PM rigid: Tom_L: average home setup won't give a problem but enterprise setups have a high chance of failing to connect
05:22 PM rigid: nope, that still redirects to 81
05:23 PM lcnc-relay: <xxcodery> https://jauriarts.org/_matrix/media/v3/download/jauriarts.org/npXxcDHsbJLzdKPVqGbRkTbA/666398fda2a35d0ca377019e.png
05:23 PM lcnc-relay: <xxcodery> lol. mirror cybertuck
05:23 PM Tom_L: i've seen that
05:23 PM xxcoder: mirror finish means its going to be very very hot
05:23 PM Tom_L: all i have to say about it is
05:23 PM Tom_L: WHY?
05:23 PM xxcoder: yup
05:23 PM rigid: (i guess home setups will get more strict in the next years.)
05:24 PM Tom_L: i'll let it go until it quits then just become a hermit :)
05:24 PM rigid: Tom_L: because: cybertruck
05:25 PM xxcoder: you'll never catch me dead with one, even if I was given one for free
05:25 PM rigid: cybertruck == crime & punishment in a single entity
05:25 PM rigid: :)
05:26 PM Tom_L: 445 is blocked but not 443 it appears
05:26 PM rigid: <- someone who loves tesla model S and roadster btw
05:27 PM rigid: Tom_L: you could just add 443 if you configure a letsencrypt cert and keep your port 81 setup active
05:27 PM rigid: i like acme.sh but there are tons of easy letsencrypt clients available.
05:29 PM Tom_L: it's been so long since i set that up i probably forgot how
05:31 PM rigid: i suppose it's apache?
05:31 PM Tom_L: yeah
05:31 PM rigid: not too familiar with that. i'm an nginx guy :)
05:32 PM Tom_L: i do the fwd on the router
05:32 PM rigid: if you can really use port 443, it's easy "apache letsencrypt" should yield some usable tutorial
05:32 PM Tom_L: if i changed it, anybody that had my link would have to change that
05:33 PM rigid: nope, you can listen on port 81 and 443 simultaniously. Like most webservers do.
05:33 PM rigid: they mostly redirect from port 80 to 443 (http -> https) but some just still serve unencrypted on 80
05:33 PM rigid: 81 in your case
05:34 PM rigid: then you could just share https://tom-itx.no-ip.biz/... (if they really don't block 443)
05:34 PM Tom_L: can i add it to fwd to the same local address?
05:35 PM rigid: hmyeah, i don't see any reason why you couldn't
05:35 PM rigid: just different port
05:37 PM Tom_L: would my internal port be 80 or 81 on that?
05:37 PM Tom_L: nevermind
05:37 PM rigid: it could be any port but i'd choose 443
05:38 PM Tom_L: probably have to reboot the router to take effect?
05:38 PM rigid: iirc apache uses something like <VirtualHost tom-itx.no-ip.biz:443> ... </VirtualHost> syntax
05:38 PM rigid: nah, just restart apache
05:39 PM Tom_L: i'm not changing the server just the router
05:39 PM rigid: well, the router needs to apply settings, too. but it'll probably reboot itself if needed
05:40 PM rigid: normally port forwarding doesn't need a reboot but there are a gazillion different routers...
05:40 PM Tom_L: try one of those with 443
05:40 PM Tom_L: nope
05:42 PM rigid: Tom_L: nope, "Connection refused"
05:42 PM Tom_L: i had to change something else and i forget what it was
05:43 PM rigid: is your actual server listening to 443? (netstat -apn | grep 443 if linux)
05:44 PM Tom_L: yeah i need to fix ports.conf
05:44 PM Tom_L: i think
05:44 PM rigid: your router should unblock 443 if you forward the router's 443 to your server's 443 but maybe you need to adjust the firewall aswell and enable public 443 access
05:45 PM rigid: yes, if you adjusted apache's defaults
05:45 PM rigid: should look like this: https://exampleconfig.com/view/apache-ubuntu20-04-etc-apache2-ports-conf
05:45 PM rigid: "Listen 81" in your case i guess
05:45 PM Tom_L: dinner...
05:46 PM rigid: bedtime... feel free to bug me
05:49 PM lcnc-relay: <roguish> ok, just touched 99.0 F
05:49 PM lcnc-relay: <roguish> heat index. feels like 102.3
05:49 PM Tom_L: it already has listen 443 in the ports.conf
05:50 PM Tom_L: what is <IfModule ssl_module> for?
05:50 PM Tom_L: should 'listen 443 be outside those?
05:51 PM Tom_L: mine looks like the one you posted except 80 is 81
06:17 PM -!- #linuxcnc mode set to +v by ChanServ
06:25 PM Tom_L: rigid, i think it's working
06:25 PM Tom_L: didn't have to change apache
06:32 PM Tom_L: can someone verify both these ports: http://tom-itx.no-ip.biz:443/~webpage/cnc/Mill_Steel/Assembly/Final/chip_guards/Chip_guard4.jpg
06:32 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Final/chip_guards/Chip_guard4.jpg
06:37 PM roycroft: tom_l: ifmodule ssl_module is generally used to define where to find the certificates and the tls parameters
06:38 PM Tom_L: ok, it was in ports.conf by default
06:38 PM roycroft: and yes, listen 443 is generally outside the ifmodule ssl stuff
06:38 PM Tom_L: turns out i didn't need to change any of that
06:38 PM roycroft: yes, it's in ports.conf
06:38 PM Tom_L: just the router
06:38 PM roycroft: if it's debian or debian-like, you generally just have to do a2enmod ssl, restart apache, and bob's your uncle
06:39 PM Tom_L: right and i did that when i set it up initially
06:39 PM roycroft: for a vanilla setup
06:39 PM Tom_L: but i just rounted 443 to 81 on the router
06:39 PM roycroft: i do interesting stuff, and it's a little more complicated than that for me, but it rarely has to be
06:39 PM Tom_L: and they both work
06:40 PM Tom_L: i just didn't wanna have to change all my links everywhere
06:41 PM Tom_L: the default apache port.conf has 443 inside those
06:41 PM Tom_L: https://exampleconfig.com/view/apache-ubuntu20-04-etc-apache2-ports-conf
06:41 PM Tom_L: practically identical to that
06:42 PM roycroft: what do you mean by changin all your links?
06:43 PM Tom_L: http://linuxcnc.org/community/
06:43 PM Tom_L: for example
06:43 PM roycroft: do you mean changing it to https?
06:43 PM Tom_L: they list that i log irc
06:43 PM Tom_L: and have a link there
06:43 PM Tom_L: no i don't care about http https
06:43 PM Tom_L: just everybody's bookmarks point to 81
06:44 PM Tom_L: not 443
06:44 PM roycroft: oh, i see
06:44 PM roycroft: well you can listen on both ports
06:44 PM Tom_L: i am
06:44 PM Tom_L: well sorta
06:45 PM roycroft: i would recommend changing your published links to the default port over time
06:45 PM Tom_L: the router redirects it
06:45 PM roycroft: and monitoring your logs
06:45 PM roycroft: after a while, you'll stop getting hits on port 81, and then you can turn it off
06:45 PM roycroft: "after a while" can be a year or more
06:45 PM Tom_L: the whole problem when i started was the isp blocks 80
06:45 PM roycroft: but the traffic to the old port will eventually die off
06:45 PM Tom_L: i'm not that concerned about it
06:46 PM Tom_L: i suppose i can start posting from 443
06:46 PM roycroft: the issue is that most folks don't know what ports are
06:46 PM roycroft: or how to specify a port in a url
06:47 PM roycroft: publishing the default makes it easier for folks to connect, as they won't tend to mess it up
06:47 PM Tom_L: it's been like this for years. i doubt i change now
06:48 PM Tom_L: i get a port complaint maybe once every couple years
06:48 PM * roycroft has said enough, and won't pursue it further
06:48 PM Tom_L: :)
06:49 PM roycroft: i'm never afraid to make a point, but i also don't keep hammering the point until the other person submits
06:49 PM Tom_L: and i'm not that savvy when it comes to setting stuff like this up
06:49 PM Tom_L: i just keep it to post pics or such every so often
06:49 PM xxcoder: isnt 8080 default backup port for http?
06:50 PM xxcoder: been eyars
06:50 PM xxcoder: years
06:50 PM Tom_L: i dunno
06:50 PM Tom_L: i bet i've had half dozen offer to host my site over the years too
06:50 PM Tom_L: i'll just KISS
06:51 PM Tom_L: it's literally on a pc i pulled out of a trash can
06:52 PM Tom_L: i'm rather surprised it's lasted as long as it has
06:52 PM xxcoder: if its always on it can virtually last years
06:54 PM roycroft: yes, it's the power cycling that tends to kill computers and computer components
06:54 PM Tom_L: been running headless for years
06:54 PM Tom_L: i think i updated it to 12 a while back
06:54 PM Tom_L: maybe...
06:55 PM Tom_L: nope still 8
06:58 PM roycroft: if it's just a web server and it's not doing any cgi then it's pretty secure, and doesn't need to be updated frequently
07:12 PM BorgPipe: www.onlinetonegenerator.com anyone listen to highfrequency all day like 10k hz ?
07:12 PM BorgPipe: i find it calming like a pyramid
07:14 PM bjorkintosh: maybe you have tintinnitus, BorgPipe?
07:15 PM BorgPipe: yep its probably from starlink, cell towers , dental fillings and 6g networks ?
07:15 PM BorgPipe: maybe that movie thx knew why brains can tonelock
07:22 PM roycroft: brain, brain. what is brain?
07:48 PM xxcoder: https://youtu.be/xWRkzvcb9FQ prettyb interesting so far
08:05 PM rdtsc_away is now known as rdtsc
08:06 PM rdtsc: @xxcoder port 81
08:08 PM lcnc-relay: <redeye_joe> is there any control boards that work with linuxcnc and the small plug in drivers like the tmc2209's and the tmc5160's?
08:11 PM lcnc-relay: <skunkworks8841> maybe talk to big_kevin420
08:13 PM lcnc-relay: <redeye_joe> ok, I am also looking for someone that might be able to help with getting remora working on a btt octopus, that would be best as I already have a few of those, and the cnc I am trying to get workign with linuxcnc and a plasma is currently running on a octopus board
08:14 PM lcnc-relay: <skunkworks8841> I think.. big_kevin420 would probably be the best with remora.. But you might want to start a forum post..
08:17 PM lcnc-relay: <redeye_joe> ok thank you
08:19 PM Tom_L: skunkworks, did you wear a straw hat on the trip to town?
08:20 PM lcnc-relay: <big_kevin420> hey hey
08:20 PM lcnc-relay: <big_kevin420> whats up, thats my jam
08:24 PM lcnc-relay: <redeye_joe> hey., i just found a forum post and the docs you posted for helping a guy, I need to read up a bit, but I am trying to use a octopus with linuxcnc and tmc5160's
08:24 PM lcnc-relay: <big_kevin420> no can do the 5160s
08:24 PM lcnc-relay: <big_kevin420> but 2209 is good to go
08:25 PM lcnc-relay: <redeye_joe> ok, I really only use the 5160's on my 4th axis, and i wont need it for this machine anymore, as it is being converted for use with plasma
08:25 PM lcnc-relay: <redeye_joe> so 2209's I will use
08:26 PM lcnc-relay: <big_kevin420> https://remora-docs.readthedocs.io/en/latest/
08:27 PM lcnc-relay: <redeye_joe> ok, let me read up and try to get firmware flashed
08:27 PM lcnc-relay: <redeye_joe> thanks
08:27 PM lcnc-relay: <big_kevin420> ok cool, let me know how it goes, or if you have any questions
08:51 PM skunkworks: Tom_L: no.. not this time.. lol..
08:51 PM skunkworks: I did wear a straw hat when I took the kids to the swimming pool..
08:52 PM skunkworks: Took all the motors out of the basement.
08:52 PM skunkworks: probably about a 1000 pounds so far
08:52 PM skunkworks: have a shit ton in the polebuilding
08:59 PM skunkworks: there are some way back in the polebuilding on a wood shelf.. They have been there since the 80's
08:59 PM skunkworks: big old 3 phase motors that probably came off things because we didn't have 3 phase then..
09:11 PM roycroft: or vfds
09:14 PM lcnc-relay: <skunkworks8841> Right.. plus they are huge old open frame motors
09:56 PM lcnc-relay: <redeye_joe> is there two different firmwares for the octopus? the info doc says there is two different for the STM32F429 and STM32F446 versions but in the github I am only seeing one firmware.bin in the octopus folder? is it for both?
10:01 PM lcnc-relay: <redeye_joe> I think I found them 🙂
10:36 PM lcnc-relay: <big_kevin420> they are seperated by chip
11:19 PM rdtsc is now known as rdtsc_away
