02:04 AM Deejay: moin
02:20 AM duatepe: Also I am reading this discussion
02:20 AM duatepe: https://forum.linuxcnc.org/10-advanced-configuration/31813-tcp-5-axis-kinematics?start=0
02:20 AM duatepe: looks good but still not clear for me because of the lack of information about linuxcnc
02:21 AM duatepe: Still I am trying to clear my mind
02:38 AM jpa-: duatepe: in linuxcnc there are axes (X/Y/Z/A/B/..) that are controlled by g-code, and joints (0/1/2/3/...) that correspond to hardware motors; kinematics connects these two
02:39 AM jpa-: and unless your machine fits one of the basic types, you end up writing your own kinematics module, takin e.g. that one above as a base
02:39 AM jpa-: the kinematics module is then in full control over what the X/Y/Z/A/B/... mean; it can decide they mean the coordinates of tool center
02:40 AM duatepe: you mean , if I build a machine in basic types then I can use TCP easly by enable it cause default kinematic equations are fit to perform it?
02:47 AM jpa-: duatepe: well, at least if it fits the "XYZ movement and A/B rotary axes" model of the xyzab_tdr_kins linked above, you can use that..
02:48 AM jpa-: there are also others in https://github.com/LinuxCNC/linuxcnc/tree/master/src/emc/kinematics but it takes some work to figure out what is the mechanical construction of each
02:49 AM jpa-: i would design the mechanics based on what is mechanically best, after all it is just a bit of code to make your own kinematics
02:53 AM duatepe: jpa- Okay all this info will be okay for start point, as much as I see it wont be easy. Thank you for information I will continue reading the doc for now.
03:51 AM duatepe: jpa- Hi jpa
03:51 AM duatepe: I have one question also
03:51 AM duatepe: https://github.com/LinuxCNC/linuxcnc/blob/master/src/emc/kinematics/5axiskins.c ---> this file is .c
03:51 AM duatepe: https://github.com/LinuxCNC/linuxcnc/blob/master/src/hal/components/xyzab_tdr_kins.comp --> but .comp and C language
03:51 AM duatepe: What is this actually
03:52 AM jpa-: .comp is C code that is just compiled with halcompile that extracts some metadata from it
03:53 AM jpa-: the plain .c kinematics modules are compiled into linuxcnc core, while the .comp ones are HAL components that can be more easily modified by user
03:59 AM duatepe: jpa- okay, so I dont know How I will use this .c or .comp file in my application yet. This is a black box for me. I will continue to read.
04:01 AM jpa-: http://linuxcnc.org/docs/html/hal/comp.html
04:02 AM jpa-: https://linuxcnc.org/docs/html/motion/kinematics.html
04:02 AM duatepe: Thank you
04:29 AM duatepe: jpa- Hi jpa, Now I found an example project in defaults which name is sim.axis.vismach.5axis.table-rotary-tilting. When I run the linuxcnc program it asks me which configuration I want to select and I selected that. It uses TCP I see. How I will get its kinematic configuration file where can I found it ? do you know that? I didnt see it in
04:29 AM duatepe: "linuxcnc/configs/sim.axis.vismach.5axis.table-rotary-tilting" file. I think it pull it in different location
04:30 AM duatepe: I think it pulls it from different location *
04:31 AM duatepe: I mean with "kinematic configuration" .c file or .comp which inludes equations
04:34 AM Tom_L: morning
04:35 AM duatepe: morning
05:03 AM jpa-: duatepe: check the "KINEMATICS" row in the .ini file
05:04 AM jpa-: that will lead you to e.g. https://github.com/LinuxCNC/linuxcnc/blob/242d9ff4f2c4576ae36d4bfee249848ee1b514c8/src/emc/kinematics/xyzbc-trt-kins.c#L2

05:07 AM JT-Cave: morning
05:42 AM travis_farmer: Morning
07:23 AM Tom_L: raining
07:23 AM Deejay: sunny
07:24 AM Tom_L: 38 / 39
07:26 AM duatepe: sunny
07:26 AM duatepe: windy
07:30 AM Deejay: feels with the wind like -10°C
07:32 AM duatepe: no , it is southwester , it means hot wind
07:33 AM travis_farmer: 20F/30F windy
07:45 AM Unterhaus_ is now known as Unterhausen
07:46 AM Unterhausen: supposed to snow tomorrow, and also get up to 50F
07:57 AM JT-Cave: 35°F Mostly Cloudy then Rain High: 46°F
07:58 AM duatepe: why you using F always Centigrat is the best :D
07:59 AM duatepe: I mean celcius
07:59 AM JT-Cave: make up your mind
07:59 AM JT-Cave: a package left EL SOBRANTE, CA on the 4th via usps and is out for delivery today
08:00 AM travis_farmer: fast shipping
08:00 AM JT-Cave: another package left EL SOBRANTE, CA 12/29 via ups and it's out for delivery today
08:03 AM travis_farmer: my 7i87 hasn't even shipped yet... course, i haven't the money to even order it yet ;-)
08:21 AM JT-Cave: time to start my chicken day
09:51 AM Unterhausen: I didn't expect to see a ladybug today
10:22 AM JT-Shop: ladybug or jap beetle?
10:47 AM Unterhausen: too small for a japanese beetle
10:47 AM Unterhausen: I think
10:48 AM Unterhausen: we do have ladybugs here, usually on the south side of the house and only rarely inside
11:42 AM roycroft: we have lots of them, but they like to stay in the garden
11:43 AM roycroft: aphids are their favorite snacks
11:45 AM JT-Shop: new year and now insurance does not cover a couple my meds for some reason
11:56 AM JT-Shop: oh well
12:02 PM bjorkintosh: health insurance is a scam and I wish it wasn't.
12:02 PM Tom_L: price hike fewer coverages
12:03 PM bjorkintosh: in-sewer-ance.
12:04 PM Tom_L: rates right up there with lawyers and politicians
12:05 PM JT-Shop: nap time
12:06 PM Tom_L: just got up to eat lunch
12:06 PM Tom_L: should i build yet?
12:06 PM JT-Shop: yup
12:06 PM Tom_L: it'll be ready when you awake :)
12:07 PM Tom_L: did discover there's only about one way to update rpi to 2.9.2
12:08 PM Tom_L: thru the web download page then do an update cause the dl page still has 2.9.1 on it
12:15 PM Tom_L: do you generate a changelog for it?
12:22 PM Tom_L: JT-Shop, PR #63 ready
01:03 PM JT-Cave: thanks
01:12 PM Tom_L: yup
01:13 PM roycroft: franz beckenbauer has left the building
01:13 PM * roycroft got to see him play once
03:00 PM XXCoder: roycroft: https://youtu.be/e_aSXC_Z3pI
03:00 PM XXCoder: check out the router
03:06 PM Unterhausen: I have thought about mounting a router on the wall. Maybe above the lathe
03:07 PM XXCoder: the jig is interesing also
03:10 PM Unterhausen: 1tb drives went up since I last bought one
03:11 PM Rab: That configuration will support the entire weight of the gantry on the X-axis ballnuts, seems pretty brutal.
03:15 PM XXCoder: if I was designing one, I probably would bump ballscrew size up by one
03:21 PM Rab: And the screws in turn are supported at one end by a floating bearing that can't support any axial load, and a more serious bearing at the motor end. If there's a single screw, the gantry might be hanging from that one bearing.
03:23 PM Rab: The wall mount is pretty neat, it just needs to be thought out. And an off-the-shelf router table might need maintenance pretty quickly.
03:37 PM roycroft: with the wall mount your y axis rails and screw(s) need to support the full weight of the gantry as well as the weight of the z axis assembly, and it's all cantilevered weight
03:38 PM roycroft: so you do need to beef those components up
03:38 PM roycroft: it can be pretty space-efficient though, and could be worth doing
03:40 PM Rab: Some rails e.g. profile type have different ratings depending on orientation. Profile rails on the Y axis might actually be happier in a hanging orientation, since the load is distributed symmetrically across both rows of balls.
03:41 PM Rab: It's not all bad, if you reorient G at 90 degrees some components will see more load and some will see less.
03:42 PM roycroft: the y axis motor(s) will have to work harder
03:42 PM roycroft: the z axis motor will have less work to do though
03:43 PM Rab: For example this is a very typical setup for a gantry router, but the Y-axis rails need to be derated since they are used in a sideways orientation: https://i.ytimg.com/vi/G25PMdUQlJc/maxresdefault.jpg
03:44 PM Rab: This is a smart arrangement for exploiting the full load capacity of at least one of the rails: https://i.ytimg.com/vi/xvEO2z9n9bw/maxresdefault.jpg
03:47 PM Rab: I claim that the Y-axis motor will see exactly the same load, if we're both talking about the axis on the gantry. But the X-axis motor(s) will have to haul the whole weight of the gantry, plus acceleration load, plus cutting forces.
03:47 PM roycroft: we're not
03:47 PM roycroft: i call the gantry - the axis on which the z axis rides - the x axis
03:47 PM Tom_L: counterweights.
03:47 PM roycroft: and the axis that supports the gantry the y axis
03:47 PM Rab: A counterweight on a pulley could mitigate some of that.
03:48 PM Rab: I see.
03:48 PM Tom_L: i did that on my sherline
03:48 PM roycroft: a counterweight would mitigate the cantilever problem but would add even more mass for the y axis motor(s) to raise and lower
03:49 PM Rab: Yeah, I think I will need a counterweight on the Z axis of my little mill project...or else a brake to keep it from riding down the ballscrew.
03:49 PM roycroft: again, not a criticism of such a design, but pointing out a factor that needs to be considered
03:49 PM Rab: roycroft, sure, acceleration load would be increased.
03:49 PM roycroft: flipping a horizontal cnc router 90 degrees won't work
03:49 PM Tom_L: gas shocks
03:50 PM roycroft: or build it on the space station
03:50 PM Tom_L: like suv hatches
03:51 PM JT-Cave: well crap I have to upgrade to 2.9.1 to use the 7i97T board
03:51 PM Tom_L: may as well upgrade to 2.9.2
03:52 PM Tom_L: i used a deb for that since debian lags
03:52 PM Rab: roycroft, as long as you don't mess up your orbit with the wrong combination of paths and rapids. I guess they'd cancel out, more or less...
03:52 PM Tom_L: he always wondered what mars was like
03:54 PM XXCoder: just got back
03:54 PM roycroft: from mars?
03:54 PM XXCoder: yep. hjow did you know that im actually musk
03:55 PM roycroft: it was the stench
03:55 PM XXCoder: damn lol
03:55 PM * roycroft has been through tacoma before
03:55 PM XXCoder: anyway it was just to mail off sensive mail
03:55 PM Tom_L: hope you didn't hurt it's feelings
03:56 PM XXCoder: glad that my health got better enough that walking couple blocks to get to mailbox dropoff barely affected me. just breathed bit harder at end
03:56 PM XXCoder: roy what did you think of video, and jig
03:57 PM roycroft: i only watched a few seconds of it
03:57 PM roycroft: both look interesting, but i'm too busy with work right now to watch the whole thing
03:57 PM XXCoder: thats fine, not everyone is neet like me
04:01 PM Roguish: Rab try a gas strut rather than a counter weight. much less mass.
04:01 PM Roguish: i have 2 on my mill's z axis
04:02 PM XXCoder: does that apply consant pressure across entire range?
04:02 PM XXCoder: im picturing it weakening as its extended
04:02 PM Roguish: yes. same pressure throughout stroke
04:02 PM XXCoder: interesting. wonder how it works
04:16 PM Tom_L: i may have done the 2.9.1 iso and upgraded, i don't remember now
04:18 PM Tom_L: JT-Shop, do i still need to run ./mesact t to check the changes?
04:19 PM JT-Shop: no
04:19 PM Tom_L: i figured not but just checking

04:39 PM Tom_L: JT-Shop, the old buildbot on linuxcnc stops at buster (11)
04:39 PM Tom_L: excuse me.. 10
04:40 PM Tom_L: bullseye is 11
04:40 PM Tom_L: in case you keep track :)
04:41 PM JT-Shop: I'm going to add what os is found to mesact
04:43 PM Tom_L: i didn't realize it wasn't :)
04:43 PM Tom_L: ahh you have the platform
04:44 PM Tom_L: kinda runnin outta room there
04:44 PM Tom_L: what are 'coordinates' for?
04:45 PM Tom_L: oh
04:45 PM Tom_L: i didn't have a config loaded
04:49 PM Tom_L: JT-Shop, what's the status box at the very bottom gonna be for?
04:58 PM JT-Cave: which one?

05:01 PM Tom_L: that one
05:01 PM JT-Cave: when you download something a blue bar shows the status of the download
05:01 PM JT-Cave: download a manual and see
05:01 PM Tom_L: ahh that's right
05:09 PM JT-Cave: crap... I forked up the push pull somehow
05:17 PM JT-Cave: add an axis and it shows up in coordinates
05:22 PM JT-Cave: crap just lost the work I just did somehow
05:40 PM Tom_L: well at least it should be fresh in your mind. i've had that happen more than once
05:46 PM JT-Cave: check it out
05:46 PM JT-Cave: almost stopped raining so time to lock up the hens
05:47 PM Tom_L: got the push fixed?
05:48 PM JT-Cave: I just deleted it and cloned again
05:49 PM JT-Cave: then added the code back in
05:50 PM Tom_L: haha you added the cartoons too
05:51 PM JT-Cave: yup
05:53 PM Roguish: recall our little discussion on the blown out plane door yesterday ????? check this https://www.politico.com/news/2024/01/08/united-bolts-planes-airlines-ntsb-00134379
05:54 PM roycroft: so someone did not adjust the torque setting on the impact wrench properly
05:55 PM Roguish: or they were stoned.
05:55 PM roycroft: or someone incorrectly specified the torque setting
05:56 PM roycroft: it's actually really good that they figured out what the cause was so quickly
05:56 PM Tom_L: so no design flaw just laziness
05:56 PM Roguish: yeah, so easy, must have been a really, really big FU
05:57 PM Tom_L: yesterday some were blaming the engineers
05:57 PM roycroft: it actually could have been a design flaw
05:57 PM roycroft: they know what caused it
05:57 PM roycroft: now they need to determine why it happened
05:57 PM roycroft: it could have been a manufacturing problem with the bolts as well
05:58 PM Tom_L: 2nd shift will blame 1st and 1st will blame 2nd
05:58 PM Tom_L: but
05:58 PM Roguish: disassemble the entire plane and put it back together correctly
05:58 PM Tom_L: they keep good records of who did what
05:58 PM roycroft: the faa will almost certainly get to the truth of the matter
05:58 PM Roguish: RTFM, if there is an M
05:59 PM Roguish: roycroft, yeah, in about 3 years. slow as snot in winter.
05:59 PM roycroft: this is what i want to know, though
05:59 PM Tom_L: one of the night class guys at the votech was a retired boeing engineer
05:59 PM Tom_L: pretty cool guy actually
05:59 PM roycroft: most cell phones, especially the expensive ones, crack when you look at them the wrong way
05:59 PM roycroft: but a cell phone was sucked out of that plane, fell 16,000 feet, and still worked
05:59 PM roycroft: how did that happen?
05:59 PM Tom_L: samsung.
05:59 PM Tom_L: :)
06:00 PM roycroft: are samsung the new hp or something?
06:00 PM bjorkintosh: it was an iPhone wasn't it?
06:00 PM Tom_L: i dunno, i like em
06:00 PM Roguish: i heard 2 phones. 1 apple, already making advertising headlines
06:00 PM Tom_L: and the mrs has an iphone and wants to go back
06:00 PM bjorkintosh: yeah it landed in bushes.
06:00 PM Roguish: not sure what the other was
06:00 PM bjorkintosh: it did not hit anything hard.
06:01 PM Tom_L: once it reached terminal velocity
06:01 PM roycroft: if it was an iphone it would have done an internal version check as it was falling, and would have self-destructed before hitting the ground, after sending the owner an email encouraging upgrading to a newer phone
06:01 PM Tom_L: it's just falling and flipping around in the air
06:02 PM bjorkintosh: and then it had a soft landing in the bushes. https://www.independent.co.uk/news/world/americas/alaska-airlines-plane-panel-iphone-drop-b2475160.html
06:02 PM Tom_L: samsung would have had google send a message to the cloud as to where to pick it up in still working order
06:02 PM roycroft: but can it get up?
06:03 PM Tom_L: i wonder who got hit in the head with the door blank
06:03 PM Roguish: AP news doesn't detail the phones.
06:05 PM Tom_L: schoolteacher in Portland
06:05 PM Tom_L: roycroft, could have been you :)
06:05 PM Tom_L: found in his back yard
06:05 PM roycroft: i'm 2 hours south of portland
06:05 PM roycroft: that door blew off way before the plane got here
06:06 PM roycroft: it would have flown almost directly over my house on the way to california, though, had it gotten that far
06:06 PM Roguish: wow, got all the way to 56 F today
06:06 PM Roguish: and no rain
06:06 PM Tom_L: plenty of rain here but not those temps
06:14 PM roycroft: it's cool and drizzly here, but not really rainy
07:41 PM Unterhausen: I somehow forgot there was a football game on
07:42 PM Tom_L: it's called monday night football for a reason
08:27 PM roycroft: i had forgotten that football exists until i turned the tv on last night and a game was on
08:27 PM roycroft: i thought football season ended around christmas
08:27 PM roycroft: i guess it doesn't
09:35 PM solarwind: Croran this is the right place for your question
09:35 PM Croran: what's the cheapest good source for custom-length extrusions in the US?
09:37 PM solarwind: what kind of material, profile, etc.
09:37 PM solarwind: child labour acceptable or no
09:38 PM Croran: 2020, black powder coat, any aluminum
09:38 PM solarwind: like standard 2020 V groove extrusions?
09:39 PM solarwind: what's custom about them?
09:41 PM Croran: only the length
09:41 PM solarwind: .....
09:41 PM solarwind: you can get that pretty much anywhere
09:41 PM solarwind: why go to misumi lol
09:41 PM Croran: sure, but what's the best deal
09:41 PM solarwind: china
09:41 PM Croran: even incl shipping?
09:41 PM solarwind: how much do you need?
09:42 PM Croran: probably 1500mm total, but as a combination of various lengths
09:42 PM solarwind: ...... are you building a Voron
09:42 PM Croran: building a open-frame PC case
09:42 PM Croran: :)
09:42 PM solarwind: you can get that for pocket change
09:42 PM solarwind: on like any 3D printer parts site
09:42 PM solarwind: 1.5m is nothing
09:43 PM Croran: hmm. even at custom lengths?
09:43 PM solarwind: you buy more than you need and cut it to length
09:43 PM solarwind: 1.5m is nothing
09:43 PM solarwind: just search amazon
09:43 PM solarwind: you'll have it tomorrow if you order now
09:43 PM Croran: hmm. I don't have a way to cut. live in an apartment.
09:43 PM solarwind: hacksaw
09:44 PM Croran: want it to look nice and powder coated ends
09:44 PM solarwind: or a butter knife, it's 6061 aluminum lol
09:44 PM solarwind: nobody powder coats the ends
09:44 PM solarwind: just paint it
09:44 PM solarwind: the ends are always bare
09:44 PM solarwind: ask in #reprap
09:44 PM Croran: what about anodized ends
09:45 PM solarwind: I thought you wanted like 100kg of it or something
09:45 PM solarwind: you can paint the ends and nobody would be able to tell
09:45 PM Croran: hmm ok.
09:45 PM Tom_L: lies
09:45 PM Tom_L: :)
09:46 PM solarwind: but half the ends would be covered anyway
09:46 PM solarwind: since you need to bolt them together
09:46 PM Croran: true, but the other half...
09:46 PM solarwind: 2020 is such a small area
09:46 PM solarwind: matte black paint from hardware store
09:46 PM solarwind: or steal your sister's nail polish
09:46 PM Tom_L: anodize it
09:47 PM solarwind: or that if you really want. it's easy
09:47 PM Croran: huh. but anodize is such a thin coating. would need to have a really nice cut to make it look good, no?
09:47 PM solarwind: Tom_L he was about to order it from misumi lol
09:47 PM solarwind: they'd charge like $500 for it
09:48 PM lcnc-relay: <big_kevin420> maybe but musumi is wicked awesome
09:48 PM Tom_L: so you lured him here
09:48 PM lcnc-relay: <big_kevin420> i wish
09:48 PM solarwind: he was in #hardware which is mostly full of gamertards
09:48 PM Croran: musubi has got spam and i don't like spam
09:48 PM lcnc-relay: <big_kevin420> theres a #hardware irc?
09:49 PM lcnc-relay: <big_kevin420> well, spam aka adverts
09:49 PM solarwind: yes but it's not what you think
09:49 PM solarwind: it's "computer hardware"
09:49 PM lcnc-relay: <big_kevin420> adblock tghough
09:49 PM Tom_L: last i heard neither was electronics
09:49 PM solarwind: geeks talking about which video card is best who don't even know what a transistor is
09:49 PM lcnc-relay: <big_kevin420> but go to a 3d printer stopre
09:49 PM solarwind: #reprap would know about extrusions
09:49 PM lcnc-relay: <big_kevin420> ohhh that hardware
09:49 PM Tom_L: they're a bunch of whiners
09:49 PM solarwind: yeah I suggested 3D printer parts store
09:50 PM lcnc-relay: <big_kevin420> well if the lenghts match, you can do just a voron kit with precuts
09:50 PM solarwind: that's the first place I'd check
09:50 PM Croran: oh voron kit is custom lengths?
09:50 PM solarwind: LOL I thought he was tryign to build a Voron kit too
09:50 PM Croran: that sounds like a neat idea
09:50 PM lcnc-relay: <big_kevin420> yeah theres on in hamilton, they have the saw in store
09:50 PM lcnc-relay: <big_kevin420> sometimes
09:50 PM Tom_L: i used to log reprap and was asked to quit. they didn't want their boss reading their chat
09:50 PM lcnc-relay: <big_kevin420> but yeah, and they have like 10 dif colours
09:51 PM lcnc-relay: <big_kevin420> lol
09:51 PM Tom_L: fckn babies
09:51 PM solarwind: you don't _have_ to listen to them
09:51 PM solarwind: it's not like they'd know if you were logging it
09:51 PM lcnc-relay: <big_kevin420> they need to be better at the internet
09:51 PM Tom_L: i was tired of their shit anyway
09:52 PM lcnc-relay: <big_kevin420> boss could read it anyways
09:52 PM Tom_L: at that time at least, every one of them was trying to sell something
09:52 PM lcnc-relay: <big_kevin420> tapped so many holes today in extrusion
09:52 PM solarwind: Most people don't understand how the internet works, especially kids
09:53 PM lcnc-relay: <big_kevin420> form taps are so boss
09:53 PM Tom_L: yes
09:53 PM lcnc-relay: <big_kevin420> dammit i hate young people
09:53 PM Tom_L: i haven't had opportunity to use one but i know they're nice
09:53 PM solarwind: Gen Z is a disaster
09:53 PM Tom_L: i like the finish on single point threading
09:53 PM lcnc-relay: <big_kevin420> i need to get some for home tyo use with 2020 extrusion
09:54 PM lcnc-relay: <big_kevin420> they leave no chips* so the extrusion is clean afterwards
09:54 PM solarwind: 2020 is too flimsy for me
09:54 PM solarwind: 4040 is the way to go for 3D printers
09:54 PM lcnc-relay: <big_kevin420> sometimes the chips compact so its hard to blow them out
09:54 PM solarwind: Or just good old A36 steel square tube
09:54 PM Tom_L: i used to roll form threads on brass
09:54 PM lcnc-relay: <big_kevin420> i work sub 1meter size
09:54 PM Tom_L: those also turn out nice
09:54 PM lcnc-relay: <big_kevin420> not to brag, but i used it in a hand drill
09:55 PM lcnc-relay: <big_kevin420> the form tap
09:55 PM lcnc-relay: <big_kevin420> and the milwaklie hand drill beat out the dewalt todaty
09:56 PM lcnc-relay: <big_kevin420> dewalt with 4amp hour couldnt form any of the holes in one shot
09:56 PM solarwind: Which model?
09:56 PM lcnc-relay: <big_kevin420> the mil got it done, but it got reaklly hot
09:56 PM solarwind: My DCD996 has never stalled
09:56 PM lcnc-relay: <big_kevin420> dewalt? regular drill
09:56 PM lcnc-relay: <big_kevin420> mil, was something m18
09:57 PM solarwind: for most tools, dewalt is generally better
09:57 PM lcnc-relay: <big_kevin420> thats massive
09:57 PM lcnc-relay: <big_kevin420> the one below that
09:57 PM Tom_L: milwaukee are hard to beat imo
09:57 PM lcnc-relay: <big_kevin420> i like the chainsaw and impact guin
09:57 PM lcnc-relay: <big_kevin420> but
09:57 PM solarwind: I do like the M12 ratchets though
09:57 PM lcnc-relay: <big_kevin420> a borrowed drill puts holes in anything
09:58 PM lcnc-relay: <big_kevin420> i have the m12 bandsaw
09:58 PM lcnc-relay: <big_kevin420> its fun
09:58 PM lcnc-relay: <big_kevin420> why do I do everythibng fun size
09:58 PM Tom_L: i looked at some of those but the neck wasn't enough for me
09:59 PM Tom_L: i cut more plate than bar
09:59 PM lcnc-relay: <big_kevin420> i had free m112 batteries and it was on sale for cheaper
09:59 PM lcnc-relay: <big_kevin420> so i said what ever
09:59 PM lcnc-relay: <big_kevin420> i cant even do a 2040
10:00 PM lcnc-relay: <big_kevin420> i have to flip it
10:00 PM lcnc-relay: <big_kevin420> its like 1.5 ionches
10:00 PM Tom_L: tablesaw :)
10:01 PM Tom_L: i cut alot of my 2" thickwall for the mill on a tablesaw with a diamond blade
10:03 PM Croran: Tom_L: how do the cuts come out with the diamond blade?
10:03 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Welding/Frame_Weld2.jpg
10:03 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Welding/Frame_Weld1.jpg
10:04 PM Croran: wait you cut steel on a table saw?
10:04 PM Tom_L: parts of it
10:05 PM Croran: huh. interesting.
10:05 PM Tom_L: some i used an angle grinder with a cutoff wheel
10:05 PM lcnc-relay: <big_kevin420> what blade do you use?
10:05 PM Tom_L: i don't remember now, some red brand blade
10:06 PM Tom_L: the abrasive wheels actually work better
10:06 PM lcnc-relay: <big_kevin420> diablo
10:06 PM Tom_L: probably
10:07 PM lcnc-relay: <big_kevin420> yeah i use a carbide tipped blade for cutting extrusion at work on one of those wood saws
10:07 PM Tom_L: i wasn't quite that brave
10:07 PM Tom_L: for steel
10:07 PM Tom_L: i have some 60 tooth
10:09 PM Tom_L: my crap old drill press was too short so you get inventive: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Drillpress.jpg
10:10 PM lcnc-relay: <big_kevin420> better than hand drilling
10:11 PM Croran: are all the plastic extrusion end caps junk or are there some decent ones?
10:30 PM XXCoder: https://youtu.be/0roVK4TPbe0 interesting. its about testing rust inhibvitors
10:30 PM XXCoder: one year
10:49 PM roycroft: is that another one of those "friends don't let friends use por-15" videos?
10:49 PM * roycroft is in a meeting and can't watch it right now
10:50 PM XXCoder: nah its just long term test of various coatings to see how long those last
10:54 PM roycroft: i am testing how well rattle can paint cures when sprayed well below the recommended ambient temperature and well above the recommended relative humidity
10:54 PM roycroft: should i have made a youtube video of that?
10:55 PM roycroft: and would i get ONE MILLION DOLLARS from all the clicks it would get?
10:55 PM XXCoder: I doubt ut would be moneymaker, but you are free to do it
11:13 PM solarwind: here's a fun thing to do
11:13 PM solarwind: take 2 grease guns and replace their bleeder valves with grease nipples
11:14 PM solarwind: then connect their hoses together to continuously pump/circulate grease between them :D
11:15 PM solarwind: not only does it give you a great wrist workout, it mixes the grease inside evenly so all the oil that settled to the bottom becomes uniform through the mixture
