12:07 AM lcnc-relay: <Elian.s@> I figured I'll need one of those little adapters, but what about the software/configuration side of things? Will i be able to read spindle load and stuff
12:29 AM lcnc-relay: <Olli (RIO)@> hy_vfd component in linuxcnc
12:29 AM lcnc-relay: <Olli (RIO)@> but it's easier using the usp port

12:32 AM lcnc-relay: <Olli (RIO)@> but it's easier using the usb port
12:42 AM lcnc-relay: <Elian.s@> Olli (RIO)@: But USB is not the most robust connector or standard l

12:56 AM lcnc-relay: <Elian.s@> I figured if I can avoid using usb, there would be less latency maybe. I am using PS/2 mouse and keyboard....

04:39 AM NetPipe: makin some herb
06:40 AM lcnc-relay: <Le_potato@> i can use 1 switch for negative and positive limit?
06:41 AM lcnc-relay: <Le_potato@> i upgraded my rails from used hiwin to chinese one
06:41 AM lcnc-relay: <Le_potato@> maaannn, way better
06:41 AM lcnc-relay: <Le_potato@> new chinese way better than shitty used
06:43 AM lcnc-relay: <Le_potato@> i have to calibrate them because while i went 300mm on hiwin, its 90mm on chinese one
06:43 AM lcnc-relay: <Le_potato@> ooo, im so exixited
07:05 AM rdtsc-w: Le_potato I think so, as long as both switches are normally closed and opening either one is detectable by LinuxCNC
07:06 AM rdtsc-w: should be able to use that for homing too
07:08 AM rdtsc-w: touch end, then move away some distance (your home location) Think Meister recently made a python tool to help illustrate homing
07:13 AM rdtsc-w: https://forum.linuxcnc.org/configuration-tools/57610-working-on-a-animated-home-setup-helper-tool
08:28 AM lcnc-relay: <wrickert@> xxcoder: I've been using the Thingino replacement firmware for cheap Chinese wifi cams for the better part of a year now. I dont have the doorbell part of my doorbell cam working but other than that I've been very happy. Certanly happy for the price point.

08:57 AM lcnc-relay: <Lesliet@> was thinking about whether it would be practical to diy a couple of wall outlet on/off controls that worked over bluetooth or something to give voice command of a few outlets. Like Alexa, but less glitchy and intrusive.
08:57 AM lcnc-relay: <Lesliet@> gf had to have alexa units in a couple of places, but they're messing up, and I never liked the privacy issues with that system
09:31 AM rdtsc-w: If the microphone appears dead, and there's a microphone disable switch, it's the switch... had to bypass one on an Echo dot.
09:33 AM xxcoder: wrickert thanks, looking. btw try not to edit large block of text, as often it will repeat in irc, but with edits :)
09:35 AM lcnc-relay: <Le_potato@> rdtsc-w: i have one sensor
09:35 AM lcnc-relay: <Le_potato@> its traditional milling machine
09:35 AM lcnc-relay: <Le_potato@> so have 2 end bump for 1 switch
09:35 AM lcnc-relay: <Le_potato@> so its have to know the positive and negative limit for the same switch
10:34 AM lcnc-relay: <wrickert@> xxcoder: Aah. My bad.
10:34 AM xxcoder: no problem
01:25 PM rdtsc-w: Le_potato that's even simpler: move (left) until switch, homed. Any other time switch is tripped, machine will stop
01:55 PM Connor: Someone with a continues rotation A or B axis ping me. I'm working on a FreeCAD operation and linuxcnc post processor (to support this) and have questions about how lcnc behaves.
01:56 PM Connor: The documentation for Rotary axis is kinda all over the place and contradicts itself.
02:18 PM Tom_L: Connor, you can look at my A config: anything _A is part of it: http://tom-itx.no-ip.biz:443/~webpage/cnc/configs/NEW_MILL/
02:18 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/configs/NEW_MILL/new_mill_A.ini
02:19 PM Tom_L: shows the joint
02:19 PM Tom_L: your post needs to be in angular units not linear
02:23 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/Rotary_test_2.txt
02:23 PM Tom_L: there's a sample output from my post. notice the A feed differences
02:24 PM Tom_L: my post outputs that in quadrants btw
03:00 PM lcnc-relay: <skunkworks@> lol - the forklift is 4 speed
03:00 PM lcnc-relay: <skunkworks@> just the linkage isn't quite working
04:08 PM roycroft: oh lord, here we go again
04:08 PM roycroft: a customer did not get an email
04:08 PM roycroft: my boss asked me about it
04:09 PM roycroft: i showed him the log entry where it was deliverd to her email provider
04:09 PM roycroft: he wants to know what happened to it
04:09 PM roycroft: i told him i have no way of knowing, and that she needs to talk to her email provider
04:09 PM roycroft: he told me i need to find out
04:13 PM xxcoder: you forgot your magic genie torch
04:13 PM roycroft: we
04:13 PM roycroft: have been over this at least a couple hundred times
04:14 PM roycroft: when mail log says "status=sent (250 ...." that means we've done our job, and it's out of our hands and purvue
04:15 PM roycroft: but yeah, maybe i need the magic 8 ball or the ouiji board to tell me what happened to it
04:22 PM pere_ is now known as pere
04:49 PM lcnc-relay: <Le_potato@> thank you rdtsc-w!
04:57 PM lcnc-relay: <skunkworks@> $160 and I didn't have to deal with it
04:57 PM lcnc-relay: <skunkworks@> https://photos.app.goo.gl/Zg2XKznvL1pN9bSq7
05:09 PM xxcoder: fun weather here
05:09 PM xxcoder: it rains, and when its sunny, its raining
05:17 PM Unterhaus_ is now known as Unterhausen
05:18 PM roycroft: we get some really good rainbows in oregon
05:19 PM xxcoder: lol saw bunch of good ones in tacoma :)
05:19 PM xxcoder: one was very bright 2 band
05:22 PM roycroft: there may be some small tornados near portland today if the weather ever comes
05:23 PM roycroft: we were supposed to have 15mm of rain here today, but we got maybe 1-2mm
05:24 PM roycroft: and the forecast for tomorrow as of this morning was for another 15mm tomorrow, but now that's been adjusted to 3mm
05:24 PM lcnc-relay: <skunkworks@> 3 speed
05:24 PM lcnc-relay: <skunkworks@> it is a 3 speed
05:24 PM lcnc-relay: <skunkworks@> seems to shift. needs some work - everything is worn ou
05:24 PM lcnc-relay: <skunkworks@> out
05:24 PM roycroft: a lot of storms seem to skirt just by us to the north
05:25 PM xxcoder: I almost cant be more north
05:25 PM * roycroft heads to town for errands and dinner
05:25 PM xxcoder: in oregon'
05:27 PM roycroft: this storm goes all the way down to san josé
05:27 PM roycroft: but there are big holes in it, and one of those holes is over my town
05:28 PM roycroft: so yeah, i think i'm going to drive right into it as soon as i leave town
05:28 PM * roycroft puts on his tolerate the rain gear before leaving
05:30 PM roycroft: and maybe i'll actually wear shoes, instead of birkenstocks
05:38 PM lcnc-relay: <skunkworks@> I usually have 1 pair of shoes I wear until they die
05:38 PM lcnc-relay: <skunkworks@> then I buy another pair
05:39 PM xxcoder: I have winter, summer and "walk aound outside near home" shoes
05:39 PM lcnc-relay: <skunkworks@> I guess I also have ski boots... does that count?
05:39 PM lcnc-relay: <skunkworks@> and dads work boots I use when i am chain sawing
05:44 PM xxcoder: I still have steel toe shoes I bought for work
05:45 PM xxcoder: its still nicely scarred
05:45 PM lcnc-relay: <skunkworks@> the oil is certainly milky
05:45 PM lcnc-relay: <skunkworks@> https://photos.app.goo.gl/dmdnTccyprWdkaUG9
05:45 PM xxcoder: forbidden eggnog
05:46 PM Tom_L: hydraulic or engine?
06:17 PM lcnc-relay: <skunkworks@> hydraulic
06:20 PM lcnc-relay: <Lucid Nonsense@> skunkworks@: I'm sure you've heard about EUSurplus who sell Mesa cards in Europe, but their main business is selling lathes that make hydraulic seals. Basically they use extremely sharp tools and CNC them out of solid polyurethane bar
06:21 PM lcnc-relay: <skunkworks@> neat!
06:21 PM lcnc-relay: <Lucid Nonsense@> Just in case your seals are unobtanium or absurdly expensive
06:22 PM lcnc-relay: <skunkworks@> I have a guy.. Now. lol
06:22 PM lcnc-relay: <skunkworks@> he will do cylinders bigger than I have..
06:22 PM lcnc-relay: <skunkworks@> and he is about 10 minutes away
06:23 PM lcnc-relay: <Lucid Nonsense@> Handy
06:23 PM lcnc-relay: <skunkworks@> I walked into his shop and he had atleast 2 telehandlers and a couple lift trucks he was working on
06:24 PM lcnc-relay: <Lucid Nonsense@> I really want a telehandler
06:24 PM lcnc-relay: <skunkworks@> me too
06:24 PM lcnc-relay: <Lucid Nonsense@> They're stupidly expensive on eBay though
06:25 PM lcnc-relay: <skunkworks@> I said that I live in a valley - and that I need one that can handle that. He pointed to one of them he was working on and it tips the end and the body to keep it level
06:26 PM lcnc-relay: <Lucid Nonsense@> My drive is extremely steep, so basically no delivery driver with anything bigger than a van will drop anything anywhere convenient
06:27 PM lcnc-relay: <Lucid Nonsense@> One of my neighbours has come to rescue with his telehandler 3 times, but I hate asking
06:27 PM lcnc-relay: <Lucid Nonsense@> Plus, last time he almost tipped it
06:28 PM lcnc-relay: <skunkworks@> oof
06:28 PM lcnc-relay: <Lucid Nonsense@> Kind of guy who won't say no even if it's a really bad idea
06:28 PM lcnc-relay: <skunkworks@> lol
06:29 PM lcnc-relay: <Lucid Nonsense@> Bet self levelling is not cheap though
06:30 PM lcnc-relay: <skunkworks@> not what I can afford..
06:30 PM lcnc-relay: <skunkworks@> more of a want than a need
06:30 PM lcnc-relay: <skunkworks@> those hydraulic hoses were a pain to wrestle out.
06:30 PM lcnc-relay: <skunkworks@> they were so stiff and the wires where very sharp
06:30 PM lcnc-relay: <Lucid Nonsense@> Gone solid
06:31 PM lcnc-relay: <Lucid Nonsense@> Yeah
06:31 PM lcnc-relay: <Lucid Nonsense@> Pouring hot water on them can help
06:31 PM lcnc-relay: <skunkworks@> sure - I just used a channel lock and a pry bar and pulled it out
06:32 PM lcnc-relay: <Lucid Nonsense@> Executive persuasion
06:32 PM lcnc-relay: <skunkworks@> hopefully the new ones go in better than the old ones came out
06:32 PM lcnc-relay: <Lucid Nonsense@> Should be a lot softer
06:32 PM lcnc-relay: <skunkworks@> should be. still waiting ont he filter
06:33 PM lcnc-relay: <skunkworks@> (to replace the milky oil)
06:33 PM lcnc-relay: <Lucid Nonsense@> Hopefully seals aren't shot all around
06:34 PM lcnc-relay: <skunkworks@> huh - the filter is at work
06:34 PM lcnc-relay: <skunkworks@> cool
06:34 PM lcnc-relay: <skunkworks@> yah - a little leaking is fine.
06:34 PM lcnc-relay: <Lucid Nonsense@> If they're really bad you'd probably see scoring
06:35 PM lcnc-relay: <skunkworks@> it doesn't have to perfect - it gets used very rarely
06:37 PM lcnc-relay: <Lucid Nonsense@> Owls are out in force winter imminent
06:39 PM lcnc-relay: <Lucid Nonsense@> Quantumikes arrived, my hair is 45 microns
06:40 PM lcnc-relay: <Lucid Nonsense@> Surprisingly consistently so
06:43 PM lcnc-relay: <Lucid Nonsense@> I don't like that the data port gaskets are held in with tiny screws though, should be toolless
06:43 PM lcnc-relay: <Lucid Nonsense@> Might have to mod that
06:46 PM lcnc-relay: <skunkworks@> I called a couple local places to make some hydraulic hoses.. The first one wondered if I had an account.. the second one didn't want to do 2 hoses.. Then I called the guy I used and he talked a bit about how he doesn't probably have the hose that works with my re-usable fittings and that I could order it maybe from the local autoparts store. So I asked him how much to just make me some with crimp on fittings.. he said - oh -...
06:46 PM lcnc-relay: ... about 150...
06:46 PM lcnc-relay: <skunkworks@> I said I would be right over
06:48 PM lcnc-relay: <Lucid Nonsense@> How many days until you find three hydraulic hose crimpers in the treasure hoard you reckon?
06:48 PM lcnc-relay: <skunkworks@> lol - I think I would know if we had some. We normally use the re-usable fittings.. I have done a ton of hoses around here.
06:49 PM lcnc-relay: <skunkworks@> I might have the hose I needed - but I didn't want to riffle through stuff
06:49 PM lcnc-relay: <Lucid Nonsense@> Know the feeling, that's why I have 5 Ethernet crimpers
06:49 PM lcnc-relay: <skunkworks@> lol
06:50 PM lcnc-relay: <skunkworks@> between work and here - I probably have atleast that
06:50 PM lcnc-relay: <Lucid Nonsense@> Yeah, but I've probably made Ethernet cables 5 times
06:50 PM lcnc-relay: <skunkworks@> oh.. I have probably done thousands..
06:51 PM lcnc-relay: <skunkworks@> and now probably a few hundred fiber splices..
06:52 PM lcnc-relay: <Lucid Nonsense@> Is it difficult? I'm doing a lot of work on the house and considering putting lots of fibre backbones in
06:52 PM lcnc-relay: <skunkworks@> https://www.youtube.com/watch?v=XvyanCuzNds
06:53 PM lcnc-relay: <skunkworks@> we wanted to have a local company run fiber in our business - they quoted about 30k... So we bought cable and a $1000 dollar splicer
06:53 PM lcnc-relay: <skunkworks@> that was a few years ago - I would assume they are cheaper
06:53 PM lcnc-relay: <skunkworks@> they are amazing machines
06:54 PM lcnc-relay: <skunkworks@> this is ours.
06:54 PM lcnc-relay: <Lucid Nonsense@> I was looking at knipex cable strippers earlier today and came across their £99 fibre cutter burnisher
06:54 PM lcnc-relay: <skunkworks@> https://www.youtube.com/watch?v=ypBunFtrOrE
06:55 PM lcnc-relay: <Lucid Nonsense@> Is it ultrasonic or something?
06:55 PM lcnc-relay: <skunkworks@> arc
06:55 PM lcnc-relay: <skunkworks@> it melts the fiber together
06:55 PM lcnc-relay: <Lucid Nonsense@> K
06:56 PM lcnc-relay: <skunkworks@> it really is amazing.. the first time I did it - I was like - wtf - it just did that?
06:56 PM lcnc-relay: <skunkworks@> so - we just bought pigtails with the ends we wanted - and spliced them into our runs.
06:56 PM lcnc-relay: <Lucid Nonsense@> Looks fancy for 1k
06:57 PM lcnc-relay: <skunkworks@> it was rather un-eventful
06:57 PM lcnc-relay: <skunkworks@> everything has just worked.
06:57 PM lcnc-relay: <skunkworks@> yes - I was really amazed.
06:57 PM lcnc-relay: <skunkworks@> https://www.ebay.com/itm/394159905300
06:58 PM lcnc-relay: <skunkworks@> (not the brand We bought - I don't remember)
06:58 PM lcnc-relay: <Lucid Nonsense@> Cool, thanks, prolly cheaper on aliexpress too
06:58 PM lcnc-relay: <skunkworks@> I would look around - and do your research.. I think I got lucky
06:59 PM lcnc-relay: <Lucid Nonsense@> Yeah, there's 40Gbit copper too isn't there
06:59 PM lcnc-relay: <skunkworks@> I ran fiber fromt he house to the tower - about 400ft. A cake walk for it.
07:01 PM lcnc-relay: <Lucid Nonsense@> Through conduit or armoured?
07:01 PM lcnc-relay: <skunkworks@> we mostly run 10gbs on the fiber. more than fast enough for us
07:01 PM lcnc-relay: <skunkworks@> but we ran single mode fiber so we could go way faster
07:02 PM lcnc-relay: <Lucid Nonsense@> So how does that work, is it two cables?
07:02 PM lcnc-relay: <skunkworks@> that is what we run - 2 fibers.. tx/rx
07:02 PM lcnc-relay: <ccatlett1984@> both single and multi mode fiber, have 1 strand per direction of communication
07:02 PM lcnc-relay: <skunkworks@> (we ran 12 fiber bundles to most places)
07:03 PM lcnc-relay: <ccatlett1984@> you ALWAYS run more strands then you need.
07:03 PM lcnc-relay: <skunkworks@> yes
07:04 PM lcnc-relay: <skunkworks@> (again - we have not had any of the inital runs fail)
07:04 PM lcnc-relay: <Lucid Nonsense@> I'm considering just running conduit with pull cords all over the place
07:04 PM lcnc-relay: <ccatlett1984@> fiber doesn't do well with pull cords
07:04 PM lcnc-relay: <ccatlett1984@> bend raduis
07:04 PM lcnc-relay: <Lucid Nonsense@> Ok
07:04 PM lcnc-relay: <Lucid Nonsense@> Good to know
07:05 PM lcnc-relay: <ccatlett1984@> if they are straight pulls, and you have access at the bends, it's fine
07:05 PM lcnc-relay: <ccatlett1984@> you can pull through a radius, but you need to have the radius in the conduit
07:05 PM lcnc-relay: <skunkworks@> I pulled fiber through 3/4 water pipe all they way up to the tower. no issues. I would have to look at the fiber I bought - it was pretty tough
07:06 PM lcnc-relay: <ccatlett1984@> for installation, plan on nothing sharper than a 6" radius
07:07 PM lcnc-relay: <Lucid Nonsense@> Yeah, probably depends on the stock, main reason Norway got Gbit internet so early was robots twirling fibre around the power cables
07:07 PM lcnc-relay: <skunkworks@> agreed
07:07 PM lcnc-relay: <Lucid Nonsense@> That should be easy enough
07:07 PM lcnc-relay: <ccatlett1984@> it 100% does, I'm certified for fusion splicing and testing
07:08 PM lcnc-relay: <skunkworks@> our maintenance department pulled all the fiber.. they did a great job
07:08 PM lcnc-relay: <skunkworks@> I bought fluke fiber testers...
07:08 PM lcnc-relay: <skunkworks@> so - still under the 30k estimate
07:08 PM lcnc-relay: <Lucid Nonsense@> I had a massive roof leak so have to pull the floor in my bedroom, which happens to be in between the network junction and the workshop
07:08 PM lcnc-relay: <skunkworks@> (that was probably another $1000 lol
07:08 PM lcnc-relay: <ccatlett1984@> a decent OTDR is still about $1500
07:09 PM lcnc-relay: <ccatlett1984@> fusion splicer (for single strand, not ribbon) you can get for $450, or a nicer model that auto aligns the cores for about $1000
07:09 PM lcnc-relay: <Lucid Nonsense@> That switches however..m
07:10 PM lcnc-relay: <ccatlett1984@> you can get 1/10gb fiber switches CHEAP on the secondary market
07:11 PM lcnc-relay: <Lucid Nonsense@> Yeah, 10Gbit isn't to problematiceven with copper, latency needs som horsepower though
07:11 PM lcnc-relay: <ccatlett1984@> 25/40gb switches are getting cheap now
07:12 PM lcnc-relay: <Lucid Nonsense@> Yeah, I've also found there's a lot of settings in NICs these days that can improve latency
07:12 PM lcnc-relay: <skunkworks@> I have had bad experience with microtik...
07:12 PM lcnc-relay: <Lucid Nonsense@> Turn off any powersaving
07:13 PM lcnc-relay: <skunkworks@> one of the switches we bought had some major hardware flaws
07:13 PM lcnc-relay: <Lucid Nonsense@> And stuff to limit CPU load
07:14 PM lcnc-relay: <skunkworks@> mikrotik
07:14 PM lcnc-relay: <skunkworks@> but - we have a lot of mikrotik hardware that has been working fine
07:15 PM lcnc-relay: <Lucid Nonsense@> OK, they were the first to make 10Gbit switches afforsable
07:34 PM lcnc-relay: <Lucid Nonsense@> Was guy Fawkes today, I have no emotional connection to it whatsoeve, but my boy and I took the waterproof boombox out blasting the Prodigy while launching and obscene amount of fireworks
07:35 PM lcnc-relay: <Lucid Nonsense@> He seemed satisfied
07:48 PM lcnc-relay: <skunkworks@> Nice
07:48 PM lcnc-relay: <skunkworks@> Not heard of that.. had to look it up
08:26 PM jdh: remember
08:50 PM lfluffywof is now known as fluffywolf
