12:55 AM Deejay: moin
04:11 AM Tom_L: morning
05:01 AM JT-Cave: morning
07:45 AM Tom_L: too quiet
07:45 AM XXCoder: shh
07:45 AM XXCoder: ;)
07:46 AM gregcnc: blah blah cnc blah
07:47 AM gregcnc: i did see post where a guy is working 3 linuxcnc computers to run a gui and two controls for a Gildemeister CTX Twin
08:05 AM Tom_L: seems like alot
08:09 AM gregcnc: I would guess easier than sorting twin spindle twin turrets with live tools in one control
08:10 AM Tom_L: possibly
08:10 AM Tom_L: not a rookie build for sure
08:34 AM JT-Cave: finally found a cutting board video that's not stupid trash and people trying to be actors and they are not
08:56 AM gloops: im a cutting board facebook group, see some nice efforts
08:56 AM gloops: but just taking the dog out
09:12 AM _unreal_: rather annoyed, part of my part I'm making got over cut, depth wise. ? and I dont get it
09:12 AM _unreal_: I saved the project files
09:12 AM _unreal_: and I rechecked everything and the numbers are CORRECT? wtf
09:12 AM _unreal_: the software litteraly inserted a different depth value
09:12 AM _unreal_: some how it mirrored the one next to it
09:13 AM _unreal_: not visable and :S I dont think it sgoing to cause any harm but WTF
09:13 AM _unreal_: I re-compiled the output GCODE and the result was drasticly different in that zone of the milling project
09:13 AM _unreal_: just weird
09:33 AM JT-Shop: I'm trying to get a practice end grain cutting board done in oak but it warps in the drum sander and I have no clue why
09:37 AM rs[m]: unreal: trust (your cam software), but verify
09:48 AM Tom_L: JT-Shop, why end grain?
09:52 AM Tom_L: heat causes warpage...
10:12 AM pcw_home: Isn't end grain used on most cutting boards so you don't cut the wood fibers?
10:14 AM Tom_L: makes sense
10:15 AM pcw_home: I have both types, Pretty sure the end grain one wears less
10:58 AM _unreal_: I didnt discover it till I cleaned up my chips
10:58 AM _unreal_: wasnt even done milling
10:58 AM _unreal_: I was like WTF....
11:00 AM _unreal_: I changed my view angle and was in shock to see that ring was as deep if not deeper then the center one. the center one was correct
11:00 AM _unreal_: so I went to my estlcam and checked all the numbers everything was right. I did a preview and shure enough it showed the gcode preview as fucked up
11:01 AM _unreal_: closed estlcam re-opened it and opened my saved file and re-generated and it showed the pre-view as being correct
11:01 AM _unreal_: I am totally dumbfounded
11:11 AM JT-Shop: end grain the knife goes between the fibers and edge grain the knife cuts the fibers
11:11 AM * JT-Shop just got a 97g egg from one of the hens... that must have hurt
11:18 AM fogl81: hello
11:18 AM gloops: howdy
11:19 AM fogl81: i am trying to connect hal:out pin to hal:io pin
11:19 AM fogl81: but i get Signal 'sig' can not add I/O pin 'pin_io', it already has OUT pin 'pin_out'
11:20 AM fogl81: if i ty to connect hal:io to hal:io and set one to false, the signal is still true
11:20 AM skunkworks: fogl81: what are you trying to do?
11:20 AM fogl81: does anybody have an idea how this works
11:20 AM skunkworks: what is the application?
11:20 AM fogl81: index_enable pin
11:21 AM fogl81: i am tying to signal to bldc compnent that index enable was reached
11:24 AM fogl81: i can manually set the pin value with setp and it functions OK
11:29 AM skunkworks: fogl81: with what? if you are hooking it to the endex enable of an encoder - they are both i/o piins
11:29 AM skunkworks: pins
11:29 AM skunkworks: and should work
11:37 AM _unreal_: my part looks good so far
11:37 AM _unreal_: getting ready to load up the new CAD drawing to do the mounting holes
11:38 AM fogl81: if there are more hal_io pins hooked together, is this open collector electrical equivalent?, Pinse can just pull low?
11:49 AM _unreal_: fewfffff ok 3 holes have been milled
11:50 AM _unreal_: was my greatest risk for breaking a bit
11:50 AM _unreal_: 4mm hole ROOT hole for 5mm M5 screw to be tapped
11:50 AM _unreal_: now for a clearence pass
11:50 AM gregcnc: 4.2mm hopefully
11:51 AM _unreal_: gregcnc, and now...... for the clearence pass
11:51 AM gregcnc: no idea what that means
11:51 AM _unreal_: err finishing pass sorry :)
11:53 AM _unreal_: mY SMALL MACHINE IS GOOD BUT ITS NOT AS RIDIGID AS i WOULD LIKE FOR IT TO BE
11:59 AM fogl81: @skunkworks, if i read pin value with show pin, will it show the input or the output... is there some documentation about this - i cant find it
12:07 PM Loetmichel: hehe, $me just makes new tracks for a toy crawler. 2 times 28h printing time says cura. THAT will be fun. ;)
12:07 PM gregcnc: loetmichel which one?
12:09 PM Loetmichel: Friend of mine posted that his old toy has disintegrating rubber tracks
12:09 PM Loetmichel: dont know the model
12:10 PM Loetmichel: https://suchanek.de/temp/defekte_raupenkette_1.jpg
12:10 PM Loetmichel: so i asked for some measurements and now printing a "real" chainlink track from PLA
12:11 PM Loetmichel: 44 chainliks per side.
12:15 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=17990&g2_imageViewsIndex=1
12:15 PM Loetmichel: hope that works
12:16 PM _unreal_: Loetmichel, likely cheaper to buy them
12:16 PM _unreal_: just saying
12:16 PM Loetmichel: its a very old toy
12:17 PM Loetmichel: i doubt you could get it
12:17 PM Tom_L: Loetmichel, still got all 10 fingers today?
12:17 PM Loetmichel: yep
12:17 PM Loetmichel: last mishap was last monday
12:17 PM Tom_L: made it thru yet another week...
12:17 PM Loetmichel: :)
12:17 PM skunkworks: fogl81: yes - that is how the i/o pin works
12:18 PM fogl81: ok, thank you for your help :)
12:30 PM tionebrr: Hello folks.
12:30 PM Tom_L: hi
12:33 PM tionebrr: I'm wondering if there is some repositories where I can find some beginner CNC to cut aluminum.
12:34 PM _unreal_: tionebrr what cnc machine do you have
12:34 PM tionebrr: I already used a chinese 6040 for a bit of time but I want something better structurally speaking.
12:34 PM _unreal_: there is no one FITS ALL how to
12:34 PM Tom_L: tionebrr, check grabcad.com
12:35 PM Tom_L: or are you looking for a better cnc?
12:35 PM _unreal_: FITS ALL meaning every cnc machine has different tollerances... especially if its DIY
12:35 PM tionebrr: Okay. Ideally it would be for PCB holes and cutout, and the occasional aluminum or brass part. I just don't know here to look for existing designs
12:35 PM tionebrr: **where to look...
12:35 PM _unreal_: hehe
12:35 PM Tom_L: grabcad probably has some designs
12:35 PM _unreal_: what kind of designs CNC designs or gcode
12:36 PM tionebrr: CNC designs
12:36 PM _unreal_: i AM TOTALLY confused...
12:36 PM _unreal_: do you need a new cnc yes or no
12:36 PM Tom_L: no surprise there
12:36 PM tionebrr: Yes
12:36 PM _unreal_: do you have a cnc
12:36 PM tionebrr: No
12:36 PM _unreal_: AHHHH OK
12:36 PM _unreal_: Tom_L, lol
12:36 PM tionebrr: ^^
12:37 PM _unreal_: ok well a 6040 typically is VERY wel suited for aluminum
12:37 PM _unreal_: VERY well...
12:37 PM _unreal_: are you looking to build or buy
12:37 PM tionebrr: yeah, it works, but... meh
12:37 PM tionebrr: Not decided yet.
12:38 PM tionebrr: I was thinking about a 3040 maybe. I believe they are a bit sturdier than a 6040.
12:38 PM tionebrr: Or just scratch build the thing from custom cut plates.
12:39 PM tionebrr: (breaking some taps in the way heh :P )
12:42 PM _unreal_: if your looking for a machine to be more rigid DIY may be your best bet
12:42 PM tionebrr: Okay that's what I thought. :)
12:42 PM _unreal_: but the hardest part is getting the tolerances your looking for
12:43 PM _unreal_: for example rail mounts have to be machined flat
12:43 PM _unreal_: most plate is not flat
12:43 PM _unreal_: they have slight deviations
12:44 PM _unreal_: and that will cause tight spots on your rails
12:44 PM _unreal_: personally I would suggest buying if you haver the money
12:45 PM _unreal_: your not likely to beat $ or break even DIY vers buying.
12:45 PM tionebrr: Okay. I think I'll just go for a 3018. They are cheap and it will be enough for my PCBs as a starter.
12:45 PM _unreal_: ESPECIALLY if your going to highe quality
12:45 PM tionebrr: Yeah, also DIY requires time which is not free at all in the end.
12:45 PM _unreal_: right
12:46 PM _unreal_: I'm building a machine and its taken me almost a year so far
12:46 PM _unreal_: still not done
12:46 PM _unreal_: but then again I'm building a machine that was not suposed to be built
12:46 PM tionebrr: Geez. A big CNC?
12:46 PM _unreal_: because the company that was suposed to cut all the parts and make it kept delaying me
12:46 PM _unreal_: so I DIY'ed one and smaller :(
12:46 PM tionebrr: I was thinking about epoxy granit also.
12:46 PM _unreal_: then the fake pandemic hit and fucked me $$ wise
12:48 PM _unreal_: I still need to collect my 100 lb steel base from that company
12:48 PM _unreal_: so pissed off about that
12:48 PM tionebrr: Yeah I had some friends in a bad shape because of the SARS-Cov2. Really...
12:48 PM tionebrr: It's not really imaginary, but the measures are a bit overkill I agree
12:49 PM _unreal_: https://www.cdc.gov/nchs/nvss/vsrr/covid19/excess_deaths.htm
12:49 PM _unreal_: its not even real, the CDC ENDED it on paper months ago
12:49 PM tionebrr: What if I built the base from aluminum extrusion but I fill the extrusion with epoxy granit?
12:50 PM _unreal_: only recognize ? 5% of the deaths as being legitimate which is about 10k
12:50 PM _unreal_: less then swine flu, H1N1
12:50 PM _unreal_: thats up to you
12:50 PM _unreal_: epooxy granite are very rigid no argument
12:50 PM _unreal_: but its also very heavy
12:51 PM _unreal_: and getting everything perfect and true is a mother
12:51 PM _unreal_: because you have to build a mold
12:51 PM tionebrr: I also like the fact that you are actually molding a frame. You don't have to cut/weld/lift...
12:51 PM tionebrr: Yeah I will need someone with a true machining rig to make the rails surfaces restifications
12:52 PM tionebrr: **rectifications
12:52 PM _unreal_: generally wood is the choise for casting an epoxy/granite frame BUT wood is stupid level subject non even surfaces
12:52 PM _unreal_: you still have to TOOL and finish all of your surfaces to a perfect finish
12:53 PM _unreal_: so againi, doenst save you time/money
12:53 PM _unreal_: and as I said THEY ARE HEAVY
12:53 PM tionebrr: Okay but I guess it would be the same finishing task as any build right?
12:54 PM tionebrr: Erf yeah, weight...
12:54 PM _unreal_: there we go now it sounds right
12:54 PM _unreal_: had to kill my milling job
12:55 PM _unreal_: got a build up of aluminum on one of the flutes
12:55 PM _unreal_: tionebrr, depends on the design
12:56 PM _unreal_: My new machine I'm building https://drive.google.com/file/d/1QLHmHYjZq8jkN6GM00Qsj9yGhNzrk_u3/view?usp=sharing
12:56 PM _unreal_: mostly recycled parts
12:56 PM tionebrr: Could someone actually make the contact surface adjustement for the rails by hand?
12:56 PM tionebrr: I guess one could just shims and adjust them rigth?
12:57 PM _unreal_: rails need to be on a constant surface
12:57 PM _unreal_: so shiming is possible but typically NOT practical
12:57 PM _unreal_: to hard to get a constant
12:57 PM _unreal_: I had one rail I ended up putting a bed of epoxy under to get it even
01:01 PM _unreal_: and that was mounted to a "" precision" aluminum square tube
01:01 PM _unreal_: much to my WTF
01:01 PM _unreal_: I paid top dollar to get
01:01 PM Tom_L: precision extrusion?
01:01 PM _unreal_: yes
01:02 PM _unreal_: one of the few things I purchased for the new machine
01:02 PM _unreal_: btw I'm making the coupling nut right now for my new cnc machine for the z threaded rod drive
01:03 PM _unreal_: https://drive.google.com/file/d/1R9M8PsXtScwVvwy2GmmWj3jaLoEGPFgH/view?usp=sharing https://drive.google.com/file/d/1R62KNB55LwPLZZ5LN-c2JGl1ZsW_UvWP/view?usp=sharing
01:04 PM _unreal_: two photos showing the different sides
01:04 PM Tom_L: not sure what i'm looking at
01:05 PM _unreal_: it came from a SAT.
01:06 PM _unreal_: its basicly a mounting block with a BIG ass almost 3" diam bearing and a timing belt
01:06 PM _unreal_: I'm building a block that will mount to the timing belt pully
01:06 PM _unreal_: and it will hold/drive the threaded rod
01:06 PM _unreal_: for the z
01:08 PM _unreal_: I'm working on cutting it out right now
01:10 PM _unreal_: god I hate doing deep cuts
01:10 PM _unreal_: always take for ever using a 1/8th
01:10 PM _unreal_: 36mm/m feed rate
01:11 PM Tom_L: use a bigger bit
01:13 PM _unreal_: I dont have one
01:13 PM _unreal_: the next size I have is 1/4
01:13 PM _unreal_: to large
01:14 PM _unreal_: I did use the 1/4 for milling the other areas
01:14 PM _unreal_: just faster
01:15 PM _unreal_: this pico brushless spindle I have has the power
01:15 PM _unreal_: arg... 50min of milling left
01:15 PM _unreal_: and I have to clean after every pass
01:15 PM _unreal_: each pass is like 8min
01:15 PM _unreal_: working on cutting the part out.
01:16 PM _unreal_: right now I may call it quits for a while and get some shit around the house done
01:16 PM Tom_L: yeah my spindle kicks ass now
01:17 PM _unreal_: no argument my old DC 200watt spindle did wonders
01:17 PM _unreal_: I mean HELLLLLLLLL it built the new aluminum mount for my new spindle LOL
01:18 PM _unreal_: -7.8mm going to 11.9mm total
01:18 PM _unreal_: sigh
01:21 PM tionebrr: _unreal_: thanks for the nice advices :)
01:21 PM _unreal_: tionebrr
01:22 PM _unreal_: why a 3018? over the larger one?
01:23 PM _unreal_: there is a massive construction difference between them
01:23 PM _unreal_: the 3018 is a TOY compaired to the 6040
01:23 PM tionebrr: Because I need at least a 3018 for milling circuits and plastics rather quickly.
01:24 PM tionebrr: And the price point of bigger and better machines does not justifies right now.
01:25 PM tionebrr: Also I want something better than a 6040, and that will not be easy to choose/build
01:25 PM tionebrr: So for a starter, 3018 seems to be a reasonable buy.
01:26 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Column_Mill_VMC.jpg
01:27 PM Tom_L: went from a sherline to that
01:28 PM _unreal_: tionebrr, not a great photo but my machine DIY
01:28 PM _unreal_: https://drive.google.com/file/d/1QiVG-3oYM0k8G7jLCvv1eaoqVGQh-K_d/view?usp=sharing
01:28 PM _unreal_: its milling aluminum RIGHT NOW
01:28 PM _unreal_: different part thats an old job
01:29 PM _unreal_: my DIY machine is very rigid
01:30 PM _unreal_: and yes the x rails are floating but they are iron pipes filled with second iron pipes and peoxy
01:30 PM _unreal_: epoxy
01:30 PM tionebrr: _unreal_: Yeah the cuts look very clean
01:30 PM _unreal_: will NOT bend
01:30 PM tionebrr: No ballscrew nor linear rails neither...
01:31 PM _unreal_: I'm using HDPE nuts
01:31 PM _unreal_: as long as I put a bit of lithium grease on the threaded rods now and then they never wear out
01:31 PM _unreal_: and the resistance is minimal
01:31 PM _unreal_: zero backlash
01:32 PM tionebrr: Nice trick
01:32 PM _unreal_: but again took for ever to build the machine, but that was again a time of low $
01:32 PM _unreal_: started bilding before my xwife and I ever got a divorce then I let it sit for prob 7 years
01:33 PM _unreal_: finished it 2 years ago
01:33 PM tionebrr: Yeah there's always this timemoney tradeoff.
01:34 PM tionebrr: Did you made the epoxy plates yourself?
01:34 PM _unreal_: NO
01:34 PM _unreal_: those are g10
01:34 PM _unreal_: all scraps
01:34 PM tionebrr: Okay
01:34 PM tionebrr: I don't remember having seen that anywhere.
01:34 PM _unreal_: you can look it up "g10 frp"
01:35 PM tionebrr: Ah I see, it's fiberglass.
01:35 PM _unreal_: very strong very heavy, very expensive
01:35 PM tionebrr: What thickness?
01:35 PM _unreal_: 5/8th I believe3
01:35 PM _unreal_: I forget
01:36 PM _unreal_: dont even think about building a machine with this stuff. would be cheaper to go with aluminum
01:36 PM _unreal_: unless you work in the marine industory or have access to it for scraps
01:36 PM tionebrr: I was thinking about fiberglass reinforced epoxy granit ^^
01:37 PM tionebrr: To cut some weight
01:38 PM tionebrr: You can orient the fibers parallel to the stresses of the design.
01:41 PM _unreal_: again not worth it
01:42 PM _unreal_: has to be ultra high density frp board that is made from layers of glass NOT chop
01:42 PM _unreal_: and again FRP g10 is heavyer then aluminum
01:42 PM _unreal_: and more expensive
01:42 PM _unreal_: and not as strong as aluminum
01:44 PM tionebrr: Okay. That is actually my first fear about epoxy granit, the brittleness of the thing.
01:44 PM tionebrr: It's very stiff but there is a cost to that I guess
01:53 PM gregcnc: Have you looked for any mills in your area?
01:54 PM tionebrr: Yeah. There is no much to be found here. I should look in Germany maybe.
01:54 PM tionebrr: I'm in east France.
03:10 PM _unreal_: https://www.youtube.com/watch?v=C5B92uryWY0
03:11 PM * t4nk_freenode takes out the popcorn and prepares to back-read
03:16 PM _unreal_: no one live?
03:16 PM _unreal_: sigh
03:19 PM t4nk_freenode: ah, again with the google login links, no thanks.
03:34 PM unterhaus_: is a significant part of the internet broken, or only on my end?
03:34 PM unterhaus_: google seems to be working
03:35 PM t4nk_freenode: what fails for you?
03:35 PM unterhaus_: twitter
03:35 PM t4nk_freenode: mmm, I don't twit
03:35 PM unterhaus_: the book where they keep your face after they ripped it off
03:36 PM unterhaus_: linuxcnc.org not responsive
03:37 PM unterhaus_: haha, xfinity, my isp
03:37 PM t4nk_freenode: yeah, it seems to work for me here
03:38 PM unterhaus_: weird that google is the only thing that works
03:38 PM t4nk_freenode: is it the same for pinging?
03:38 PM t4nk_freenode: maybe a dns problem
03:38 PM unterhaus_: just mail though, not the search engine
03:39 PM t4nk_freenode: is there a response when you ping the domains?
03:39 PM unterhaus_: I can ping google
03:39 PM _unreal_: I'd say your ISP
03:39 PM _unreal_: I sem to have no internet issues
03:40 PM t4nk_freenode: you's say anything ;)
03:40 PM unterhaus_: linuxcnc.org responds to pings but not xfinity.com
03:40 PM _unreal_: currently I'm doing an OUTSIDE edge finish pass on my coupler I'm building
03:40 PM _unreal_: poped up for me
03:40 PM _unreal_: instant
03:40 PM t4nk_freenode: "America's best Internet experience. Period."
03:41 PM t4nk_freenode: :b
03:41 PM unterhaus_: yeah, verizon teased us with getting fiber, but they didn't follow through
03:41 PM _unreal_: says the foreigner
03:41 PM unterhaus_: I think I can see their fiber from my desk
03:41 PM _unreal_: :)
03:42 PM unterhaus_: did you ever think that everyone's a foreigner to someone?
03:42 PM t4nk_freenode: just like everybody has a mother
03:42 PM t4nk_freenode: except _unreal_
03:42 PM t4nk_freenode: he was CNC'ed into this world
03:42 PM unterhaus_: out of starboard
03:42 PM t4nk_freenode: from a piece of ....
03:42 PM t4nk_freenode: :))
03:43 PM unterhaus_: that's why he's a star
03:43 PM t4nk_freenode: ;)
03:44 PM unterhaus_: I was ready for some mindless doomscrolling, and the internet failed me
03:44 PM t4nk_freenode: ouch... $45 for 30 days of Internet + $35 one-time modem purchase
03:44 PM t4nk_freenode: prepaid internet
03:45 PM unterhaus_: who is that?
03:45 PM t4nk_freenode: xfinity :))
03:45 PM t4nk_freenode: who in his right mind would buy that
03:45 PM unterhaus_: yeah, is that half price for the first year?
03:45 PM _unreal_: almost ready to pull my part
03:46 PM t4nk_freenode: euh.. no I think that is 1 month
03:46 PM unterhaus_: not sure why you would buy a month of internet
03:46 PM unterhaus_: it's a big waste for us, but what can ya do?
03:47 PM unterhaus_: have to go downstairs and see if it's a network issue
03:48 PM unterhaus_: I bought a modem without reading the reviews, bad idea
03:48 PM Tom_L: which one?
03:49 PM unterhaus_: integrated wifi, 2.4ghz is unreliable
03:49 PM unterhaus_: as in, it works for about an hour
03:49 PM unterhaus_: tp link. I'd figure out which one but I can't reach amazon to look it up
03:50 PM t4nk_freenode: lol
03:51 PM t4nk_freenode: I'd still say you have a dns issue
03:51 PM t4nk_freenode: might test that by replacing your dns server with 8.8.8.8
03:53 PM Tom_L: read their privacy statement first
03:53 PM t4nk_freenode: lol, who are you kidding?
03:54 PM t4nk_freenode: they're everywhere
03:56 PM unterhaus_: the computer hard wired to the modem works
03:58 PM Eric__: I guess now I have to check the router in the basement
03:59 PM _unreal_: my part is flawless
03:59 PM _unreal_: love it
04:12 PM Eric__: okay, it's a really weird network issue
04:28 PM Eric__: what's the alternate google dns server other than 8888?
04:29 PM Tom_L: 8844?
04:30 PM Eric__: doesn't seem to be a dns
04:31 PM Eric__: seems to be my wireless ap on this end somehow
04:31 PM Tom_L: For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844.
04:32 PM Tom_L: For IPv4: 8.8.8.8 and/or 8.8.4.4
04:32 PM Eric__: thanks
04:36 PM Eric__: maybe my ap knows I'm plotting to replace it and it's sabotaging the effort
04:36 PM Tom_L: :)
04:36 PM Eric__: I just flashed a router with dd-wrt to use as a bridge
04:44 PM unterhaus: now I'm wondering if the router decided it needed to change its local network ip range again
04:56 PM jymmmm: howdy
04:57 PM jymmmm: Just got in a 300A DC shunt, kinda scary to think about :)
05:00 PM unterhaus: the router downstairs has the default admin login, maybe I should change it
05:00 PM t4nk_freenode: let me handle that for you ;)
05:01 PM unterhaus: outside admin not enabled and it's behind another router
05:01 PM t4nk_freenode: so, can you twit-twat again?
05:02 PM unterhaus: so unless you live next door ...
05:02 PM unterhaus: nothing is working still
05:02 PM unterhaus: really weird, maybe my ap settings got garbled
05:03 PM t4nk_freenode: at least you know how to keep busy hehe
05:03 PM unterhaus: i could remote desktop into one of the basement computers
05:03 PM t4nk_freenode: I'm in pain myself; gotta make decisions about where to position the knobs on my psu
05:04 PM unterhaus: I suggest the front
05:05 PM t4nk_freenode: I got some more stuff to add, but I´ m not sure where I should put it all
05:05 PM t4nk_freenode: yeah, lol.. the front..
05:05 PM t4nk_freenode: there's gonna be more than 1 front :|
05:05 PM unterhaus: you keep using that word, I don't think it means what you think it means
05:06 PM Tom_L: who needs no stinkin knobs anyway!
05:06 PM unterhaus: once we get bill gate's vaccine, the microchips will allow us to control our psu's by thinking
05:06 PM jymmmm: On the bottom, then you wont lose them
05:07 PM unterhaus: it probably has more than one bottom
05:07 PM t4nk_freenode: it has.
05:07 PM t4nk_freenode: unless I put some more flip switches on the bottom
05:07 PM unterhaus: see, bill gates already injected microchips
05:07 PM t4nk_freenode: then it'll be tough
05:09 PM unterhaus: I almost bought a dremel 4300 when I was in lowe's yesterday
05:10 PM unterhaus: should hold out and get the milwaukee cordless die grinder
05:17 PM unterhaus: I guess chrome is broken on this comp
05:19 PM unterhaus: nice, after all that it was chrome's fault
05:22 PM t4nk_freenode: no
05:22 PM t4nk_freenode: your fault
05:22 PM t4nk_freenode: for using chrome
05:23 PM t4nk_freenode: *sigh* darnit, if only I'd just take a drill and drilled some friggin holes already :|
05:23 PM t4nk_freenode: I guess I'll do some more planning instead
05:25 PM unterhaus: yeah, thought about changing the other day
05:25 PM unterhaus: firefox is so annoying though
05:25 PM Tom_L: oh by all means use IE
05:26 PM JT-Cave: LOL
05:28 PM Tom_L: JT-Cave, any pics of your cutting board?
05:28 PM JT-Cave: no, not proud of what I have so far lol
05:28 PM Tom_L: heh
05:29 PM JT-Cave: really not sure the wood I chose was good for that
05:29 PM Tom_L: kindof open grain for that you think?
05:30 PM JT-Cave: yea, that's what I was thinking even though it's oak the grain is pretty open
05:30 PM JT-Cave: going to get some black walnut, cherry and hard maple
05:31 PM Tom_L: maple would probably be good
05:32 PM JT-Cave: any of those are close grain so good for end grain cutting boards
05:35 PM Tom_L: how do you go about flattening (for lack of a better term) endgrain?
05:36 PM JT-Cave: on the drum sander, it is 22" wide
05:36 PM Tom_L: hard or impossible to plane isn't it?
05:37 PM JT-Cave: I can plane up to 15" and when the insert cutter head gets here next week end grain is not a problem
05:37 PM Tom_L: huh
05:38 PM JT-Cave: you an plane end grain with an insert cutter head but not with a straight knife head
05:38 PM Tom_L: ok
05:39 PM JT-Cave: https://mywoodcutters.com/LuxCutIIIHead_for_DELTA_15_INCH_Planer_Model_22-785
05:39 PM JT-Cave: that's what's on the way to me
05:39 PM JT-Cave: time to cook some burgers on the grill
05:40 PM XXCoder: planar?
05:40 PM XXCoder: dont that need to be nice and even
05:41 PM XXCoder: wonder how inserts is aligned for that
05:44 PM Tom_L: yeah i saw that the other day
05:47 PM roycroft: excellent, jt-cave
05:47 PM roycroft: you won't regret investing in that upgrade
05:48 PM roycroft: you're still going to need the drum sander for the last few passes on end grain cutting boards, but at least you won't go through the pain of trying to thickness them with the drum sander
06:06 PM unterhaus: walnut is commonly used for cutting boards, but it's open grain
06:18 PM XXCoder: roycroft: so its accurate enough for rough
06:19 PM XXCoder: then sand em for smooth
06:19 PM roycroft: the issue is not accuracy
06:19 PM roycroft: it's the difficulty of cutting into end grain
06:19 PM roycroft: it tends to tear out badly
06:20 PM roycroft: with edge grain you can get an almost glass-smooth finish in a thicknesser with a helical cutterhead
06:20 PM XXCoder: nice
06:20 PM roycroft: but not with end grain
06:21 PM roycroft: a sander can make end grain very smooth
06:21 PM roycroft: but you're going to be taking passes of about 0.010" with a drum sander
06:21 PM roycroft: while with a thicknesser you can usually take passes of 0.065" or more
06:27 PM XXCoder: nice
06:27 PM XXCoder: gets rid of gouges too i bet
06:32 PM unterhaus: I think luthiers are the last bastion of homemade thickness sanders
06:33 PM t4nk_freenode: mmm I was thinking of cnc'ing a guitar in the future, for fun
06:33 PM roycroft: and folks like matthias wandel
06:33 PM unterhaus: someone gave me some linear scales. I think they haven't been moved in quite some time
06:33 PM roycroft: i have a delta drum sander
06:34 PM t4nk_freenode: heh, all a person could ever need is a blunt file.
06:34 PM roycroft: i'm starting to make japanese style kumiko lamps, and need to thickness some little pieces of basswood to 3mm thick
06:34 PM unterhaus: 50/50 chance of having the cable exit the wrong direction, so of course it's headed the wrong way
06:34 PM roycroft: the drum sander works brilliantly for that
06:35 PM roycroft: my helical head thicknesser can go down to about 6mm
06:37 PM unterhaus: is a thicknesser better than a planer?
06:39 PM unterhaus: I tried using a lever indicator for dialing in my linear scale and all it showed was the rail was bowed
06:40 PM unterhaus: which brings up our motto here at unterhausen industries, "if you don't like the runout, use a crappier indicator"
06:55 PM enleth: two tapered gibs snapped on the lathe within two weeks - cross slide first, then compound slide, the adjustment screw tabs came right off
06:55 PM enleth: why don't manufacturers mill the slots that form those tabs with a rounded corner endmills is beyond me
06:56 PM enleth: thin cast iron part with stress risers built in straight from the factory
06:58 PM enleth: the only saving grace is that they snap off pretty cleanly so it doesn't take much prep work to drill and ream a hole, then loctite in a ground dowel
06:59 PM enleth: (an endmill shank, in this particular case)
06:59 PM Tom_L: got spare endmill shanks layin around ehh?
06:59 PM Tom_L: :)
07:00 PM enleth: by the dozen, and the pile gets bigger and bigger even though I can't remember ever having ordered any
07:00 PM enleth: makes you wonder
07:02 PM enleth: anyway, if I'm ever in charge of designing a machine tool with dovetail gibs, which is unlikely, I'll be damn sure to have the gib slots milled with a bullnose endmill
07:24 PM unterhaus: I'm having trouble imagining the slots breaking the gibs
07:25 PM unterhaus: but no sharp corners is a good design goal
07:30 PM unterhaus: I got my cordless router, seems nice. This channel is about woodworking and chickens, right?
07:43 PM Tom_L: and on occasion cnc?
07:44 PM roycroft: as long as you're making parts for a chicken shack, especially if you're making them out of wood
07:55 PM tionebrr: Hey guys. Anyone tried one of those: https://www.aliexpress.com/item/32933630603.html
07:55 PM tionebrr: ?
07:56 PM Tom_L: damn, estop is bigger than the mill
07:57 PM Tom_L: and likely out of reach if the axis is fwd
07:58 PM Tom_L: i say no estop on that would be a good thing
07:59 PM tionebrr: I found a video and it's apparently badly hacked together
08:03 PM Tom_L: 7x11 work area with little z
08:03 PM Tom_L: sure doesn't look like you'd get 7" from that
08:04 PM tionebrr: The screw nuts are the brass shitty type, anti backlash made with water hose
08:04 PM tionebrr: noisy as hell
08:04 PM tionebrr: The wire for the spindle are as thin as a headphone jack cable
08:05 PM jdh__: don't buy it.
08:05 PM tionebrr: I will not.
08:05 PM Rab: tionebrr, at least X/Y use supported rails, which is an improvement over most AliExpress stuff in that class.
08:05 PM tionebrr: I don't want to pay $300 for a nice steel sheet work
08:06 PM tionebrr: Yeah the frame may be okay indeed Rab
08:07 PM Tom_L: i guess for the price you can't ask for much more
08:07 PM tionebrr: I found these also, but the shipping is crazy expensive.
08:07 PM tionebrr: https://www.aliexpress.com/item/4000218008981.html
08:08 PM Rab: Haha, that's because it's cast iron.
08:08 PM Tom_L: shipping!
08:09 PM tionebrr: Anyone in Europe making that kind of frame?
08:09 PM Rab: That'd actually make a pretty convincing little mill.
08:09 PM tionebrr: Yeah ! Once dialed in bet this think could chew anything
08:10 PM tionebrr: **thing
08:26 PM enleth: unterhaus: here's an example: https://i.ytimg.com/vi/eXM5hMR9u4k/maxresdefault.jpg
08:26 PM enleth: unterhaus: this one failed in the same manner, the crack isn't as clean though
08:28 PM enleth: unterhaus: most tapared gibs are made that way, there's a slot milled near the end that accepts a collar on the adjustment screw
08:29 PM enleth: unterhaus: there's a nice view of one assembled but not screwed in: https://lh3.googleusercontent.com/proxy/EpqY3v5geTBfTS17uWKj41wgEYoyQ7DebEz8ryz30m92JELOp9qUNo_H0-zNw49ZiQs26o05TSifqN7KlqDEQiqYQ-DEfIwOrQg
08:29 PM enleth: so that nub on the front likes to snap off and I have a feeling that it would be way less likely to do so if the damn slots were milled with rounded corners
08:30 PM enleth: the collar on the screw would get rounded edges and it would still work perfectly well
08:31 PM enleth: one popular way of fixing this: https://i.imgur.com/yCyw1qwh.jpg
08:32 PM enleth: I could use a pin instead as the notch on my gibs was quite ways back from the front end
08:34 PM enleth: it's an easy fix all things considered, but it always happens when you're in the middle of something else and suddenly you are getting sidetracked fixing the machine
09:18 PM _unreal_: sigh, cutting paper shims on my laser etcher
09:25 PM t4nk_freenode: that's worth a deep sigh!
09:25 PM t4nk_freenode: *sigh*
11:08 PM jymmmm: wooff
11:22 PM Tom_L: meow
11:25 PM t4nk_freenode: growl
