12:46 AM Deejay: moin
01:30 AM lcnc-relay: <ranga> Apparently it "works" though the feed rates I'm sure are very limited
01:30 AM lcnc-relay: <ranga> every promo video shows it probing, not cutting.
01:31 AM XXCoder: that cnc kickstarter?
01:31 AM lcnc-relay: <ranga> not the scammaker, the carvera
01:31 AM lcnc-relay: <ranga> which apparently does _work_ some youtubers have shown it miling ali
01:32 AM lcnc-relay: <ranga> but... I definitely wouldn't want to push it, the specs make a 3D printer sound power hungry.
01:32 AM XXCoder: carvera air is being kickstarted
01:32 AM XXCoder: it has bunch of videos showing it in operation, cutting stuff. meh
01:33 AM lcnc-relay: <ranga> oh is it? I have KS blocked because its full of garbage.
01:33 AM XXCoder: most ks tend to go well
01:33 AM lcnc-relay: <ranga> I've only seen youtubers playing with it.
01:33 AM XXCoder: its tech stuff that tend to fail
01:33 AM XXCoder: 3d printers being the worse
01:33 AM lcnc-relay: <ranga> The only KS I've funded that's turned out well, was the 70mai dashcam one.
01:34 AM lcnc-relay: <ranga> Everything else has turned out to be something that I could have bought for less on ali
01:34 AM XXCoder: I only had 4 fail out of 30? something
01:34 AM XXCoder: 3 printers and one other tech
01:36 AM XXCoder: my most favorite was kickstarter to help school launch few ballons to space
01:36 AM XXCoder: got pictures and one card that went to space. my card was #1 lol
01:36 AM XXCoder: it will never be valuable but cool
01:40 AM lcnc-relay: <ranga> I mean, "do good recklessly" is an absolutely valid approach to life
01:53 AM XXCoder: I liked to support some science
01:54 AM XXCoder: some artprojects
01:54 AM XXCoder: didnt cost me a whole lot. 2 failed 3d printers probably could cover rest twice
01:54 AM XXCoder: if not triple
01:55 AM Guest26: I'm having trouble setting up a YY axis and have been reading docs for hours. Can i ask how in here?
01:55 AM XXCoder: hi. what trouble opn y axis setup specifically?
01:58 AM Guest26: in the .ini they are both named Y in there axis, but joint 2 and 3. when i load up the AXIS GUI they have different buttons to jog
01:59 AM XXCoder: ahh configuration issue. hopefully someone will answer in hour or two. pretty quiet at this time
02:00 AM Guest26: yea no worries, i was dredging forums other night and saw something about Y and -Y and maybe a HAL edit as well.
02:00 AM XXCoder: cool :)
02:01 AM lcnc-relay: <ranga> The 3D printer folks set them up as XYZ and UVW... Not sure if that's a thing linuxcnc can do (assuming you're not talking about two independent motors feeding the same Y
02:01 AM lcnc-relay: <ranga> )
02:02 AM XXCoder: yeah joints is each movement thing, and axis can have one or more joint for it
02:02 AM XXCoder: I just cant remember how it would work, as I only made basic one joint per axis machine
02:02 AM Guest26: Yes two independent motors for one axis
02:12 AM Guest26 is now known as MyBeer
02:18 AM rue_mohr: At some point I need to develop servo code that uses two sloppy geared drives against each other to remove the lash
02:19 AM rue_mohr: I can see a few methods
02:19 AM rue_mohr: have one motor pull and have the other 'let out' for position change
02:19 AM rue_mohr: or constant force on one motor
02:20 AM rue_mohr: sounds the same but coded slightly different
04:34 AM solarwind: Can someone give me a sanity check? https://documents.milwaukeetool.com/54-24-2260.pdf
04:34 AM solarwind: Please see part number 1: "Chuck screw"
04:35 AM solarwind: This is a left hand thread 6mm screw
04:35 AM solarwind: They are specifying the torque at ~30 Nm
04:35 AM solarwind: Is that a typo? "314.6 +/- 10.8 inch·lb"
04:35 AM solarwind: That's A LOT of torque for a 6mm PH3 screw
04:37 AM solarwind: It's not exactly an M6 screw, slightly smaller but https://www.fastenermart.com/files/metric_tighten_torques.pdf the standard max torque for a high strength M6 screw is 18 N·m
05:03 AM jpa-: https://documents.milwaukeetool.com/54-06-2740.pdf another milwaukee manual says "Torque screw to 461 kg/cm" which is not a torque unit at all, but taking it as kg*cm, gives similar 45 Nm
05:08 AM jpa-: https://documents.milwaukeetool.com/54-06-2995.pdf yet another says 100 lb*in, which sounds reasonable
05:12 AM jpa-: i guess for hammer drill they want the maximum that the screw can take
05:12 AM jpa-: preloading it close to elastic limit
05:20 AM JT-Cave1: morning
05:21 AM lcnc-relay: <travis_farmer> Morning 🙂
05:21 AM solarwind: jpa- thanks
05:22 AM solarwind: I neve use the hammer feature. I actually ordered the non-hammer model and they still sent me the more expensive hammer model *facepalm*
05:22 AM solarwind: I hate low end hammer mechanisms, so uselss
05:22 AM solarwind: they just add weight and reduce precision of the spindle
05:23 AM solarwind: I have proper rotary hammers of every size if I need to intimidate an asshole neighbour
05:24 AM solarwind: and yes I LOVE the retard "ft/lbs" you seen on the websites of typical midwest tool manufacturers websites
05:25 AM solarwind: Never once seen N/m though

05:36 AM Tom_L: morning
05:36 AM solarwind: Morning yourself
05:36 AM solarwind: I haven't gone to bed yet
07:37 AM lcnc-relay: <travis_farmer> wait... Tom_L has a yacht??? i thought he was on a cruise ship...
07:39 AM lcnc-relay: <travis_farmer> my yacht is a single-seater, human-powered 12-footer...
07:43 AM bjorkintosh: all this time, I never realized there was a log bot in here.
07:43 AM lcnc-relay: <travis_farmer> LMAO, Tom_L runs it
07:43 AM bjorkintosh: if it were a snake, it would have bitten me several times over already!
07:44 AM lcnc-relay: <travis_farmer> maybe it did...
07:44 AM bjorkintosh: Maybe you're right.
07:49 AM JT-Cave1 is now known as JT-Cave
07:50 AM -!- #linuxcnc mode set to +v by ChanServ
07:50 AM JT-Cave: and I wrote the bot sorta
07:52 AM lcnc-relay: <travis_farmer> i often thought of setting up a similar bot... on my server... but never got around to it
07:54 AM * JT-Cave starts his chicken day
07:56 AM bjorkintosh: <travis_farmer> you can buy one on ebay.
07:56 AM bjorkintosh: https://www.ebay.com/itm/294163434275
07:57 AM bjorkintosh: etsy also has a few roundtuits.
07:57 AM lcnc-relay: <travis_farmer> ... not quite what i was getting at... lol
07:58 AM bjorkintosh: but you said ...
08:30 AM lcnc-relay: <travis_farmer> found a Python and PHP IRC log... now i just have to hack it to fit...
08:34 AM -!- #linuxcnc mode set to +v by ChanServ
08:35 AM Tom_L: on the road again....
08:40 AM JT-Cave: https://github.com/jethornton/JT-Logger
08:48 AM lcnc-relay: <travis_farmer> hmmm, looks a little easier... thanks JT will fall back to that if this one craps out, as i suspect it will.
08:58 AM lcnc-relay: <travis_farmer> yeah, it failed (old PHP functions)... moving on to JTs code...
09:20 AM lcnc-relay: <travis_farmer> hmmm, i thought i had python2.7... turns out i have 3
09:25 AM lcnc-relay: <travis_farmer> log
09:26 AM travis_farmer: hmm, mine is missing
09:28 AM c-log2: travis_farmer: Nothing has been logged today, #linuxcnc index https://www.tjfhome.net/irclog/%23linuxcnc/index.html
09:29 AM travis_farmer: BWAHAHAHAHAHA!
09:30 AM lcnc-relay: <travis_farmer> there, gotta take trash to dump now... 🙂
09:59 AM roycroft: i may have to start doing that soon, when i move
09:59 AM roycroft: there is trash pickup at the new place, but very limited recycling
10:00 AM roycroft: it may be better for me to just go to the transfer station to take care of all of that stuff

10:13 AM c-log2: Tom_L: Today's Log https://www.tjfhome.net/irclog/%23linuxcnc/2024-04-13.html
10:13 AM JT-Shop: you on the way home?
10:13 AM Tom_L: Yup
10:14 AM Tom_L: Not sure how to Kill the 2nd bot from here
10:15 AM bjorkintosh: the correct thing would be for the bot creator to trigger it using a different command.
10:15 AM bjorkintosh: like log2
10:15 AM Tom_L: left the port at 7:30
10:16 AM JT-Shop: you past houston yet?
10:17 AM Tom_L: 170 mi from Dallas
10:17 AM JT-Shop: nice
10:18 AM roycroft: vectric 12 is out now
10:18 AM roycroft: it's a free upgrade for me, fortunately
10:19 AM Tom_L: You can Kill the 2nd bot if you want to
10:19 AM Tom_L: I just can't do it from here
10:20 AM Tom_L: ssh isn't working very good
10:21 AM Tom_L: should be home by 6pm
10:23 AM roycroft: i'm heading up to the new place in a few minutes to tear out walls and pull electric wires
10:24 AM Tom_L: traffic wasn't bad in houston today
10:26 AM lcnc-relay: <travis_farmer> On toilet. Will kill second bot. In a minute
10:27 AM Tom_L: it may rejoin though
10:27 AM lcnc-relay: <travis_farmer> I have it in ssh
10:28 AM Tom_L: It's not hurting anything
10:28 AM lcnc-relay: <travis_farmer> Ok...
10:30 AM Tom_L: are you running one with the same name???
10:30 AM lcnc-relay: <travis_farmer> C-log2
10:30 AM Tom_L: Cause that wont work
10:31 AM lcnc-relay: <travis_farmer> Yours is just c-log
10:31 AM Tom_L: and redundant
10:32 AM lcnc-relay: <travis_farmer> I can change commands...
10:34 AM Tom_L: good idea
10:35 AM Tom_L: At first i thought mine was running a 2nd instance
10:36 AM Tom_L: But it didntshowin ssh
10:37 AM lcnc-relay: <roguish> good morning.... pissing rain again....
10:39 AM Tom_L: kinda hard to manage, going down the road @ 90mph
10:39 AM bjorkintosh: nah Tom_L it's just a rogue bot. not yours.
10:40 AM lcnc-relay: <roguish> guess you haven't been on our freeways out here....
10:40 AM Tom_L: I figured that out
10:42 AM Tom_L: JT-shop, i see you' ve been busy
10:43 AM travis_farmer: log2
10:43 AM backup-log: travis_farmer: Today's Log https://www.tjfhome.net/irclog/%23linuxcnc/2024-04-13.html
10:43 AM travis_farmer: better?
10:43 AM Tom_L: not worse
10:46 AM Tom_L: JT-shop, run from line working good now?
10:49 AM rue_mohr: can you just select the line and click run?
10:49 AM Tom_L: ooo up to 0.1.1 now
10:49 AM Tom_L: Rue, yes
10:49 AM rue_mohr: good good
10:50 AM Tom_L: basically..
10:50 AM rue_mohr: I had to make sure on mine that I locked out that feature when it was running so you could edit a line ahead of the program counter without changing the program counters position
10:51 AM Tom_L: You need to make sure the spindle etc are on
10:51 AM rue_mohr: yea, on mine thats up to the use
10:51 AM rue_mohr: r
10:51 AM rue_mohr: I usually just select the lines that do that and click step
10:52 AM rue_mohr: Tom_L, well that sucks having been clouded out of the eclipse
10:53 AM Tom_L: I sometimes mark the line then add a m3 ahead of it
10:54 AM Tom_L: Or start at a tool change etc
10:55 AM rue_mohr: do you have a pause built in for all your tool changes?
10:55 AM rue_mohr: custom def?
10:58 AM Tom_L: It waits for a manual tool change
11:01 AM Tom_L: Part of the manual tool change comp
11:05 AM Tom_L: i'll check in later...
12:23 PM travis_farmer: i tried to get backup-log setup as a daemon, but it would not work right...
12:34 PM travis_farmer: there, finally!
12:34 PM travis_farmer: log2
12:34 PM backup-log: travis_farmer: Today's Log https://www.tjfhome.net/irclog/%23linuxcnc/2024-04-13.html
12:42 PM lcnc-relay: <travis_farmer> quiet in here, now that i am done farting around... 😉
01:01 PM XXCoder: it smelled a lot
03:02 PM lcnc-relay: <big_kevin420> fucking samsung dryer roller use a 13mm bearing
03:39 PM lcnc-relay: <big_kevin420> something i wish more engineers would understand instead of having me make ridiculous or something you can buy
03:41 PM lcnc-relay: <big_kevin420> the home machinist in me wants to spend all day converting them to roller bearings(instead of bronze bushings). but the professional machinist in me says "fuck that, buy them from piece of shit jeff bozos. dont waste time making purchase items and spend the whole day not machining."
03:41 PM roycroft: a big part of engineering is doing a cost-benefit analysis
03:43 PM roycroft: the state of oregon just passed the teethiest right to repair law in the nation
03:43 PM roycroft: it's still not good enough, but it's a good start
03:44 PM XXCoder: nice!
03:46 PM roycroft: yeah
03:47 PM roycroft: ours is the only law that requires the ability to repair things with used parts
03:47 PM roycroft: apple scrambled to reengineer the iphone 15 so it could be repaired with used parts
03:47 PM roycroft: they see the oregon law as a model for the rest of the nation
03:47 PM roycroft: not that they want it to be, but they're being realistic
03:52 PM lcnc-relay: <travis_farmer> sorry for the farting XX 🙂 but it seems to run smoothly now 🙂
03:55 PM lcnc-relay: <travis_farmer> maine passed a fair one roycroft, now the government is trying to kill it
03:55 PM joakimk: I'm working on being able to cut a pcb on a copper plated fiberglass plate using a CNC machine (Roland SRM-20). I'm using Eagle, followed by FlatCam. I need some advice on how to cut (carve?) when the piece is not perfectly flat
03:56 PM joakimk: I "zero" the Z-axis using the "chuck drop" method, but the height is not the same all over. So the carving (i.e. the traces) vary too much across the board
03:58 PM joakimk: Often, the job starts out quite nicely on one end (e.g. left half) of the board, but then -- after half the job is done -- the traces become non-existent when the machine works on the other end of the board
04:00 PM bjorkintosh: joakimk, what is the cause of the height differences?
04:00 PM bjorkintosh: is it predictable?
04:00 PM joakimk: the plate is slightly bent, or uneven :(
04:00 PM bjorkintosh: there's no pre-process to fix that before hand?
04:00 PM bjorkintosh: it'll eliminate your headaches.
04:00 PM joakimk: I have to pry it loose after cutting the board profile. I use double sided tape to fasten the larger piece to a bit of wood while cutting the profile
04:00 PM joakimk: then I have to, you know, get the piece off after
04:00 PM joakimk: ... with a spatula
04:01 PM joakimk: also, not confident the plates (from AliExpress) are 100% even to begin with
04:02 PM lcnc-relay: <travis_farmer> machine the wood you attach to so it is flat to the machine
04:02 PM joakimk: but the spatula doesn't help... Maybe I should fasten the plate using screws or something other than tape/glue, so I can more easily pluck out my part after cutting.Thing is, I need to fasten the plate to some sacrificial plate while cutting
04:03 PM joakimk: but after cutting my piece, I don't use a wooden part beneath it. When doing the carving, I fasten it to the thing that came with the machine -- the metallic part which you can screw open and closed, and will clamp a part down
04:04 PM joakimk: what's that thing called?
04:04 PM lcnc-relay: <travis_farmer> vice?
04:05 PM joakimk: yes, I think so! This thing https://rolanddg-ae.com/all-products/mpx-95-impact-printer-accessories/
04:07 PM joakimk: so, to cut my piece out, I need to fasten onto a sacrificial part of wood. Then, I remove it and clamp in the vice for etching top and bottom layer. That's where I get problems. I'd think the part sits quite flat in the vice, but the part itself is not 100% even
04:08 PM joakimk: of course I need to first try to just be more gentle removing the part from the wood (I use double sided tape). Try using some adhesive solvent spray, and being careful not to apply vertical pressure
04:09 PM joakimk: but would it help to somehow clamp the part down, along all sides, or maybe at all four corners? It that a "known method" that helps?
04:09 PM lcnc-relay: <travis_farmer> sounds like the vice is out of square with the machine
04:09 PM joakimk: no I don't think its the vice... If the part itself (the copper plate) is warped, I'll have just these problems, wouldn't I? Isn't that more likely than the vice being the problem?
04:10 PM joakimk: I wish it would somehow auto-adjust Z while carving ;)
04:10 PM joakimk: or allow me to compensate while carving...
04:10 PM lcnc-relay: <travis_farmer> there could be small variations in thickness of the PCB
04:11 PM lcnc-relay: <travis_farmer> yeah, it needs auto leveling like my Ender 3
04:11 PM joakimk: yes, that too
04:12 PM bjorkintosh: for an auto z to work, you'd have to probe the part.
04:12 PM bjorkintosh: or. correctly predict where the high and low points are.
04:12 PM joakimk: don't think this machine is that advanced
04:12 PM bjorkintosh: or. find a better way of holding the part.
04:12 PM joakimk: any recommendations?
04:13 PM bjorkintosh: hmm.
04:13 PM bjorkintosh: poka yoke.
04:13 PM joakimk: maybe I should try carving top and bottom traces first -- before cutting the profile out at the very end
04:13 PM bjorkintosh: you'd have to think a bit.
04:14 PM joakimk: hehe, I have been at this for quite some time :P But, it's only a hobby project so I'm learning the hard way
04:14 PM bjorkintosh: sometimes it's the only way.
04:15 PM bjorkintosh: I mean, you mentioned different approaches.
04:15 PM joakimk: if a part is indeed "lifted" slightly (by being bent with a spatula) on one side, do you think it would help or alleviate the problem if I were to clamp the part down along all sides, using some kind of metal frame? Does that sound sensible?
04:16 PM bjorkintosh: why not?
04:16 PM bjorkintosh: it's just metal.
04:16 PM bjorkintosh: it's used to being beaten upon.
04:16 PM joakimk: well, middle is fiber glass
04:16 PM joakimk: copper plated
04:16 PM bjorkintosh: hmm I see.
04:16 PM joakimk: but maybe it would "flatten out" if it was held down with force (on all sides)
04:17 PM bjorkintosh: can you use a wire to lift it up instead of the spatula?
04:17 PM bjorkintosh: would that work?
04:17 PM joakimk: that's a good idea!
04:17 PM joakimk: first, solvent spray, then wire
04:17 PM joakimk: be more careful, I guess ;)
04:18 PM bjorkintosh: wire is the tried and true way used on the potter's wheel.
04:18 PM joakimk: yes
04:18 PM lcnc-relay: <travis_farmer> how thick is the plate
04:18 PM joakimk: Approx. 10x15cm/3.94x5.91"
04:18 PM joakimk: ah sorry
04:19 PM joakimk: 1.5mm
04:19 PM joakimk: so 10x15cm and 1.5mm thick :)
04:19 PM bjorkintosh: what's that in moon walker units?
04:19 PM joakimk: 0.06"
04:19 PM joakimk: I believe?
04:19 PM lcnc-relay: <travis_farmer> you don't have a base metal plate?
04:20 PM bjorkintosh: that's pretty thin.
04:20 PM joakimk: lcnc-relay no... when I carve the traces? no...
04:20 PM joakimk: it does "sit" in the vice though, on the edges of it
04:21 PM lcnc-relay: <travis_farmer> get like a plate of aluminum about 1/4 inch (6mm?) thick to adhear the PCB to
04:21 PM joakimk: but I need to flip it, to carve the other side
04:21 PM joakimk: more solven + wire then?
04:21 PM bjorkintosh: joakimk, lcnc-relay is just a relay. the actual person's name follows immediately after.
04:21 PM joakimk: ah
04:21 PM bjorkintosh: there're numerous people using the relay.
04:22 PM joakimk: thanks
04:22 PM bjorkintosh: no worries.
04:22 PM lcnc-relay: <travis_farmer> i am on Discord, so it is a relay to IRC
04:23 PM joakimk: the job is actually a three-stage process: 1) cut the profile (the actual dimensions of my PCB design), 2) carve top layer (traces), and 3) flip the board and carve bottom layer
04:23 PM joakimk: the X/Y origo has to be the same (or very close) for steps 2 and 3
04:25 PM joakimk: but OK! Try to use wire (and more care) after step 1, and also try to have some flat support underneath the part for steps 2 and 3 (aluminum or something)
04:25 PM lcnc-relay: <travis_farmer> Hmm. if you had a metal mill i would say take a plate of aluminum, machine a 2-axis "fence" into the plate, and but your PCB into the fence
04:26 PM joakimk: yes, but all my jobs have different dimensions. So it would be hard to reuse the thing for the next project
04:27 PM bjorkintosh: and clamping it down is out of the question?
04:27 PM joakimk: I do think the CNC machine would be able to do this type of milling
04:27 PM joakimk: no I think I could try clamping it! Is this something one might be able to buy, or is this something I'd have to try to make
04:28 PM bjorkintosh: depends. there are numerous types available.
04:28 PM joakimk: could you please send me a link, so I could see an example? If that's not too much trouble :)
04:28 PM joakimk: just so I know what we're talking about
04:29 PM bjorkintosh: for work holding?
04:29 PM joakimk: yes
04:29 PM bjorkintosh: ooh. let's see.
04:29 PM bjorkintosh: what's the machine you're working with again?
04:29 PM joakimk: SRM-20
04:29 PM joakimk: Roland
04:29 PM bjorkintosh: so solutions range from magnets to vacuums to c clamps ...
04:30 PM joakimk: :)
04:31 PM bjorkintosh: but for something that tiny ...
04:31 PM bjorkintosh: you're really limited, I'm afraid.
04:32 PM joakimk: as in, the thickness?
04:32 PM joakimk: too thin?
04:32 PM bjorkintosh: http://axotron.se/blog/category/cnc/page/2/
04:32 PM bjorkintosh: no the machine's enclosure and everything else.
04:33 PM joakimk: aaha
04:33 PM bjorkintosh: you'll have to get creative.
04:34 PM joakimk: when cutting the part out from the overall plate (the profile 1st stage), do you think I need to secure the entire plate with tape (to the wooden block)? Or could I just clamp the sides? Would the middle piece -- the one being cut out -- risk flying loose when being cut free?
04:34 PM bjorkintosh: I cannot tell.
04:34 PM joakimk: If I didn't have to use so much adhesive (tape), I could just pick out the part when done
04:34 PM joakimk: seems like that's what's going on in your link
04:35 PM bjorkintosh: if it's clamped down, it won't go anywhere.
04:35 PM joakimk: but the larger part is clamped down, not the part you actually cut loose
04:35 PM bjorkintosh: oh I see what you mean.
04:35 PM joakimk: :)
04:35 PM bjorkintosh: you'll have to leave tabs on there to be cut or broken off.
04:36 PM joakimk: that's what's normally done when you cut something using CNC?
04:36 PM joakimk: cut out a middle piece?
04:36 PM bjorkintosh: sometimes, absolutely.
04:36 PM joakimk: tabs?
04:36 PM bjorkintosh: yeah. when working with plates.
04:36 PM joakimk: for safety=
04:36 PM bjorkintosh: otherwise, as you observed, it will fly off.
04:37 PM joakimk: I guess it might
04:37 PM joakimk: I'll try tabs! And less adhesive :) Thanks for all the helpful advice!
04:37 PM bjorkintosh: I used to cut out long sections of metal from square tubes on a laser cutter. without the tabs, it was an unpredictable disaster.
04:38 PM joakimk: :-|
04:38 PM bjorkintosh: yeah. whacking the laser head was not cheap.
04:38 PM bjorkintosh: and whack it did, if the tabs didn't hold.
04:38 PM joakimk: ouch
04:39 PM joakimk: would you expect a laser cutter could "etch" traces through a copper plating (like 1.4 to 2.8 mils)
04:40 PM joakimk: without cutting straight through the entire 0.06" plate? Or reflecting, and damaging the laser -- or the operator's eyes!!
04:40 PM joakimk: scared of those lasers...
04:40 PM bjorkintosh: yes it can.
04:40 PM bjorkintosh: and you need shields/goggles.
04:41 PM bjorkintosh: the only time I had trouble with a laser beam was when I pointed a dollar store laser pointer at my eyeball.
04:41 PM bjorkintosh: I don't recommend it.
04:41 PM joakimk: :-o
04:42 PM joakimk: I hope you're ok
04:42 PM bjorkintosh: oh it's been months.
04:42 PM bjorkintosh: i haven't done it since :-)
04:42 PM joakimk: hehe
04:42 PM joakimk: so no permanent damage
04:42 PM joakimk: not reading this in braille?
04:42 PM bjorkintosh: who's Louis Braille?
04:42 PM joakimk: hehe
04:43 PM joakimk: but "yes it can", you said... Was that re using the laser for etching (only so deep), or "yes it can damage stuff"
04:43 PM joakimk: or both
04:44 PM bjorkintosh: both.
04:44 PM joakimk: but is laser on metals (like copper) generally a bad idea, or quite straight forward. Using normal safety measures for lazers
04:45 PM bjorkintosh: it's fine.
04:45 PM joakimk: would probably be less sensitive to plate/material "flatness"
04:46 PM joakimk: than physical carving, requiring actual touch
04:46 PM joakimk: (have NO idea what I'm talking about now)
04:46 PM bjorkintosh: hmm. it depends on how strong (S) you set the beam.
04:46 PM joakimk: and then, more damage
04:46 PM joakimk: :P
04:46 PM bjorkintosh: right.
04:46 PM bjorkintosh: there's gotta be a way to flatten the material.
04:46 PM joakimk: think I'll stick to the good old V-bit
04:47 PM joakimk: yes
04:47 PM joakimk: have some ideas to try out on Monday
04:47 PM joakimk: I hope tabs will leave my part more undamaged (i.e. flat), so carving will be OK. This doesn't have to be perfect; I'm "just" trying to make some prototype PCBs
04:48 PM joakimk: before ordering a batch from abroad. Need to see that my design works, and that components fit, and sit in the right place wrt. housing etc etc
04:48 PM joakimk: and I don't want to mess around with all those acids, for etching a PCB. Which is the normal hobbyist approach
04:49 PM joakimk: spent way too much time and effort on this already, but that's what a hobby is for, isn't it? :)
04:51 PM joakimk: got to be going :) Thanks again for the chat and for your help!
04:52 PM bjorkintosh: yes.
04:52 PM bjorkintosh: 'holding tabs' or 'bridges' are what you want to search for
04:52 PM bjorkintosh: if you need more googling.
05:00 PM joakimk: thanks again :) Have a good day!
05:00 PM bjorkintosh: enjoy

06:05 PM JT-Shop: so I was asked today if ladder jacks can be used to mount a ladder to a truck...
06:06 PM XXCoder: pre-darwin award?
06:07 PM JT-Shop: lol
06:07 PM JT-Shop: I added to the description if you don't know what a ladder jack is you don't need them
06:08 PM XXCoder: yay I dont need one then lol
06:08 PM JT-Shop: one won't do anything
06:09 PM XXCoder: lol one pair
06:16 PM * JT-Shop calls it a night

06:32 PM JT-Cave: there's nothing like home
06:32 PM Tom_L: 9 hrs isn't bad
06:33 PM XXCoder: need ruby shoes to get home faster
06:36 PM Tom_L: that was 1/2 hr for lunch for the 'kids'
06:36 PM Tom_L: looks like we had 0 rain here but alot of wind
06:37 PM Tom_L: duh, no backlog on this pc.. it was off

07:08 PM Tom_L: few more there
07:09 PM JT-Cave: that's some green eggs lol
07:09 PM Tom_L: was alot of fun for them
07:09 PM XXCoder: no green ham tho lol
07:10 PM Tom_L: green pancakes
07:10 PM Tom_L: if the ham were green i might pass
07:10 PM JT-Cave: yup
07:15 PM Tom_L: we were able to park within walking distance of the terminal: http://tom-itx.no-ip.biz:81/~webpage/temp/24_trip/parking1.jpg
07:15 PM Tom_L: just past the yellow building
07:16 PM Tom_L: we came out the end door of the one in the foreground

07:57 PM Tom_L: to try and give you a sequence
07:58 PM Tom_L: mdi looks alot better
