12:31 AM CaptHindsight[m]: roycroft: how telecom gets handled should be a clear signal of what is wrong with guberment
12:54 AM Deejay: moin
02:38 AM travis_farmer: G'Morning :D
02:38 AM XXCoder: yo
03:23 AM travis_farmer: is coolant required to mill aluminum on a CNC router table, or can i just get away with an air blower for chip evacuation, and a dust vacuum?
03:24 AM XXCoder: wd-40
03:24 AM XXCoder: possibly with mister or just you spray it yourself
03:24 AM sensille: i just mill dry, it's fine
03:25 AM XXCoder: i guess keeping it reasonable so it dont weld into endmill
03:25 AM travis_farmer: Hmmm... conflicting answers ;)
03:25 AM XXCoder: it does depend on machine as usual
03:26 AM sensille: my experience is limited, but on my 24k spindle it works fine as long as i evacuate the chips
03:26 AM XXCoder: 24k rpm?
03:26 AM sensille: especially important when milling slots
03:27 AM travis_farmer: my router does 22k (5HP 3PH 220v)
03:27 AM XXCoder: wow thats pretty powerful one
03:27 AM XXCoder: mines 400w lol
03:28 AM XXCoder: (I used to run big machines at work)
03:28 AM sensille: 24k rpm, yes
03:28 AM sensille: 800W iirc
03:30 AM travis_farmer: my spindle came with the machine (48" X 48") that i only paid like $600 think
03:30 AM XXCoder: lol my entire machine cost me less
03:31 AM XXCoder: unless you meant your entire machine. if so, thats a rocking deal
03:31 AM travis_farmer: entire machine, without electronics
03:32 AM sensille: i mostly use 3mm endmills. maybe you need cooling for larger endmills
03:33 AM * travis_farmer853 uploaded an image: (1024KiB) < https://libera.ems.host/_matrix/media/r0/download/jauriarts.org/KwHmxCvrTdnyzoQuUtXpICHt/20210723_160813.jpg >
03:33 AM travis_farmer853: my machine
03:33 AM XXCoder: really depends on how well it transfer heat into chips
03:38 AM travis_farmer: my biggest issue with coolant or wd-40, is when i use my router to route wood, i need it free of oils
03:39 AM XXCoder: yeah as well as try just stright cut with no coolant
03:39 AM XXCoder: maybe with air blower
03:39 AM XXCoder: as long as it stays clear it wont recut chips or weld into endmill
03:40 AM travis_farmer: ok. how much air from blower? i don't have a lot of CFM air availible...
03:40 AM XXCoder: not sure. you'll have to figure things out
03:41 AM travis_farmer: ok, i see
03:41 AM XXCoder: in cuts where it just flies off its fine with none maybe
03:41 AM XXCoder: grooves is.. special like sensille says
03:42 AM travis_farmer: i have a bunch of 1/8 carbide end-mills, i will try with those, and see. i have plenty if i break or burn one
03:43 AM XXCoder: yeah
03:43 AM XXCoder: or weld lol
03:44 AM travis_farmer: yup, lol
03:44 AM XXCoder: you can recover a welded endmill but its no fun
03:45 AM travis_farmer: i have a bunch of pieces of 2" X 2" X 1/4" aluminum pieces i could test with too.
03:46 AM sensille: i can mostly just leave the chips there as long as there is enough room to the sides. otherwise i use a vacuum
03:46 AM XXCoder: i work from assumation that he has zero budget
03:47 AM * travis_farmer has zero budget, currently
03:48 AM sensille: when making the tool paths it is often possible to make the slot wider than the endmill and use a small stepdown, so that there's always room to the sides. that already helps immensly
03:49 AM sensille: but i'm only a beginner hobbyist
03:50 AM XXCoder: well you do know more about CAM side of things
03:52 AM sensille: and to recover endmills drain cleaner helps, Loetmichel gave me that tip
03:52 AM sensille: it dissolves aluminum
03:53 AM travis_farmer: so keep it off my aluminum router table then, right? ;)
04:13 AM travis_farmer: i can't wait until i get my new, bigger CNC shed built... though with the current prices of building materials... i am wondering if i can even afford it with just my IRS tax refund
04:38 AM Loetmichel: sensille / travis_farmer: only the drain cleaners that have "NaOH"(caustic soda) in them work though. not the "bio" ones.
04:38 AM Loetmichel: Caustic soda dissolves aluminium buit leaves steel and tungsten carbide untouched
04:39 AM travis_farmer: ok, good to know. thanks :)
04:39 AM chris_99: not heard of bio drain cleaners before, do they use some kind of enzymes or..
04:39 AM Loetmichel: yep
04:42 AM Loetmichel: its either enzymes or life bacteria
04:42 AM Loetmichel: something that makes Fat water dissolvable
04:43 AM Loetmichel: (basically the same that caustic soda does. Thats how you make soap: boiling animal/plant fats in caustic soda make the fats into soap, which is dissolvable in water)
04:44 AM JT-Cave: morning
04:45 AM Loetmichel: its also how drain cleaners work in the first place: they break the organic residue (hairs/fats) in the drain down into something water soluble that can be carried away
04:45 AM Loetmichel: s/in the drain/clogging the drain
04:46 AM Loetmichel: ... chemistry is a wonderful thing sometimes :)
04:47 AM travis_farmer: i hated chemistry... all i could ever make was a smoking blob of black sludge...
04:50 AM Tom_L: morning
04:51 AM travis_farmer: G'Morning all those just waking up ;)
05:48 AM AlfredoPalhares4: Hello, are any of you guys here running a business and making parts for sell here with linuxcnc or is just a hobby to you guys ?
05:48 AM AlfredoPalhares4: that is big
05:49 AM travis_farmer: hobby, though i hope to make money with it... and what is big?
05:50 AM JT-Cave: I design and build automatic assembly machines
05:50 AM travis_farmer: oh, my machine is big, lol, yeah it is :)
05:50 AM JT-Cave: but I'm slowing down...
05:53 AM AlfredoPalhares4: travis_farmer i see if are on irc, so do dont see the threads
05:54 AM travis_farmer: nope, i had to check Discord to see what you ment
05:54 AM travis_farmer853: but i can see them here 😉
05:57 AM travis_farmer853: this is the machine in motion, but only a dry-run (not cutting material):
05:57 AM travis_farmer853: https://youtu.be/LDz3lmUYNqs
06:24 AM JT-Cave: roycroft, Slowness in sendmail I've found 9/10 times is related to dns. Check your resolv.conf settings and make sure your dns servers resolve both your local machine name and the names of machines connecting.
06:25 AM JT-Cave: what does that mean?
07:00 AM chris_99: Does anyone ever use any milling services out of interest (i guess you likely have your own machines though :), i just got a quote for $150 for a little keychain thing, that i was kind of surprised by the cost of. I submitted it to a SLM service for £30, not sure how well that'll turn out though
07:30 AM Tom_L: chris_99, design cost, setup cost, programming cost and finally running a part
07:31 AM Tom_L: so if you're not wanting a bunch it's going to drive the cost per item way up
07:32 AM chris_99: ah i see, so it'd be a lot easier for them to make lots
07:32 AM Tom_L: the consumer never sees it that way though
07:32 AM Tom_L: of course
07:32 AM Tom_L: there are built in costs just to get a first article then the more you make the cheaper they get
07:41 AM chris_99: out of curiosity if i wanted a cheap cnc milling machine just to play with, are machines such as 'CNC 3040' reasonable, i think they can cut aluminium
07:49 AM JT-Cave: as the part count increases the overhead costs get spread out more so the cost per part is lower
07:50 AM JT-Cave: a guy wanted me to make a bearing housing for a riding lawnmower from steel so when he hit something it wouldn't break I told him $500 and he said for a $25 part?
07:52 AM ZincBoy[CAON]066: LOL. I have had the same reactions. My time isn't free so all the design, programming, and setup needs to be paid for.
07:58 AM ZincBoy[CAON]066: The 3040 machines can be fine as long as your expectations are in line with their capabilities. These are light duty machines so heavy cuts in aluminum are not going to be possible. You will need to use light cuts and appropriate endmills. Also, if you have no machining background expect a learning curve there as well.
07:59 AM Loetmichel: ZincBoy[CAON]066: and a steep one at that
08:00 AM Loetmichel: they can perfectly do alu and brass though if you keep your endmills below 3mm diameter and the depth of cut below 0.1mm or so
08:02 AM chris_99: cheers, yeah i don't have a machining background, it'd be something to try and learn some of the basics with. It'd be mainly for aluminum
08:03 AM chris_99: sorry bit confused by 'depth of cut below 0.1mm' does that mean you wouldn't be able to say mill a 2mm hole though a 2mm piece of aluminium
08:22 AM -!- #linuxcnc mode set to +v by ChanServ
08:22 AM -!- #linuxcnc mode set to +v by ChanServ
08:22 AM ZincBoy[CAON]066: No, it means that you can only mill a feature 0.1mm at a time. A 2mm hole would typically be done with a drill but could be done pecking an end mill. Based on your questions it would be best to do some research and training courses on line on CNC machining. That will give you a much better place to start from and you are much less likely to end up with an expensive paperweight.
08:24 AM travis_farmer: even in wood
08:24 AM chris_99: cheers ZincBoy[CAON]066 will definitely do some research first, before buying, will try and find an 'idiots guide to milling' ;)
08:25 AM Tom_L: if all you care to mill is aluminum, a high speed spindle may be fine for you
08:25 AM Tom_L: if you plan to cut steel etc it may not be
08:25 AM sensille: chris_99: it's worth it, though. i have a 6040 and it really is fun
08:28 AM chris_99: sensille: cool :) will google that one too
08:29 AM sensille: probably quite similar
08:29 AM sensille: 800W spindle, water cooled
08:42 AM Tom_L: you will be challenged with an 800w spindle
08:42 AM Tom_L: but maybe ok for a starter
08:45 AM sensille: only for aluminum, nearly always at 24k
08:46 AM sensille: +wood
10:13 AM travis_farmer: well, not a good day to finish setting up my LCNC test computer... the thunder rolls, and i haven't got a battery backup on that system yet...
10:21 AM roguish[m]: fricking UPS lost my pulleys coming from Breco..............
10:22 AM travis_farmer: what?!?!?
10:27 AM roycroft: this low pressure system just won't go away
10:27 AM roycroft: yesterday was supposed to be the last day of rain
10:27 AM roycroft: then today was
10:27 AM roycroft: now it's going to rain tomorrow as well
10:28 AM travis_farmer: almost like mother-nature is against us, roycroft
10:28 AM roycroft: fortunately today is a light day as far as my cabinet project goes
10:28 AM roycroft: all the drawers are glued up, so no more drawer sides to sand and finish
10:29 AM roycroft: i just have to apply finish to the outsides of the last four, and then i can install them
10:29 AM roycroft: but i'm back to taking an hour or longer between coats of shellac again, due to the coolness and high humidity
10:29 AM roycroft: vs. the 5-10 minutes that it normally takes
10:30 AM roycroft: but i'll get them installed today yet, and then it's on to the next phase
10:31 AM roycroft: travis_farmer: we haven't been able to have an in-person country fair for two years, and i think that nature has decided it likes not having all those people around, and is pushing back now that we're returning to the land
10:32 AM travis_farmer: lol, yeah, i think you may be right
10:35 AM roycroft: oh well, at least fire season hasn't started
10:56 AM * travis_farmer needs to get some lunch...
11:22 AM * travis_farmer has completed lunch (couple of toasted cheese sandwiches)
11:33 AM roguish[m]: roycroft: get used to the weather. just saw NOAA is figuring that La Nina is probably going to continue into next year. You stay wetter, we stay drier.....................
11:36 AM * travis_farmer heads back out to workshop, now that thunder storm has moved out.
12:21 PM roycroft: yeah, it's definitely turning out to be a serious la niña year
12:32 PM CaptHindsight[m]: isn't that the boat Columbus sailed on when he discovered America after the Vikings and many Asians
12:32 PM Loetmichel: wasnt that the santa maria?
12:34 PM CaptHindsight[m]: legend has it he sailed on three
12:34 PM CaptHindsight[m]: https://en.wikipedia.org/wiki/Ni%C3%B1a
12:35 PM Loetmichel: ah
12:36 PM Loetmichel: i KNEW there was a maria in there ;)
12:37 PM Loetmichel: I can remember stuff i learned 40 years ago... but i cant remember my wifes birthday. Brain is a strange thing :(
12:44 PM CaptHindsight[m]: someone made a globe that showed the travels of Vikings from 1000 through the 1800's, there is evidence they traveled as far west into North America as Iowa
12:48 PM Loetmichel: why does that remind me of doug and his "boat the internet built" on youtube?
12:48 PM Loetmichel: "well, lets build a biiiig steel boat... in the middle of nowhere with no river close by..." :)
12:57 PM CaptHindsight[m]: https://www.youtube.com/watch?v=UvVI55uq1bU
01:00 PM CaptHindsight[m]: https://www.youtube.com/watch?v=ZwhvRYKaJmc
01:02 PM CaptHindsight[m]: now back to machining https://www.reddit.com/r/specializedtools/comments/tv68u8/fixing_locomotive_wheels_while_on_the_track_found/
01:04 PM pcw--home: 5m means 5ss
01:05 PM pcw--home: whoops wrong window...
01:12 PM CaptHindsight[m]: Loetmichel: do you use conducting or RF absorbing coatings much?
01:13 PM CaptHindsight[m]: or is it mostly fabbing metal shields?
01:13 PM Loetmichel: CaptainHindsight: copper dust paint, yes
01:13 PM Loetmichel: but only for the "lower grade shielding2
01:14 PM Loetmichel: the higher tiers need more dampening than that can achieve
01:17 PM CaptHindsight[m]: Loetmichel: which brand of copper coat?
01:19 PM Loetmichel: no idea. have to look at a can at the company on monday. ping me or i'll forget.
01:22 PM * JT-Shop is happy with the fix for the ebike rack
01:22 PM TurBoss: hurray! \o/
01:36 PM roycroft: have you gone on a cruise with the bike yet, jt-shop?
01:37 PM travis_farmer: ok, i got my LCNC test computer up and semi-running... with the same old configs, i get an error on the commandline, yet LinuxCNC loads. :hm2/hm2_7i80.0: error finishing read! iter=9
01:37 PM travis_farmer: i can ping the mesa card with reply
01:38 PM JT-Shop: I did a short ride yesterday but the clamp system that holds the rack to the frame came loose so I redesigned to use a much better system
01:39 PM travis_farmer: but LinuxCNC will not connect to the mesa to control the machine...
01:40 PM Tom_L: config error
01:40 PM travis_farmer: https://github.com/travis-farmer/linuxcnc/tree/master/configs/my_LinuxCNC_router
01:40 PM travis_farmer: my configs, that worked before
01:41 PM Tom_L: what's the error
01:41 PM travis_farmer: hm2/hm2_7i80.0: error finishing read! iter=9
01:42 PM JT-Shop: that's a a cpu too slow issue iirc
01:42 PM pcw--home: "error finishing read" usually means latency issues on the host PC
01:42 PM JT-Shop: or maybe not..
01:42 PM JT-Shop: or maybe so
01:42 PM travis_farmer: hmmm... figures
01:42 PM * Tom_L shrugs... who knows :)
01:43 PM Tom_L: increase the servo period?
01:43 PM pcw--home: basically means too many packets timed out so the driver gives up
01:44 PM pcw--home: if you have a Intel MAC, make sure you have RX IRQ coalescing disabled ( man hm2_eth )
01:45 PM JT-Shop: you can check the threshold and packet time with my Mesa Configuration Tool
01:45 PM travis_farmer: ok, i will check that tomorrow, as it is too hot in shop now
01:45 PM pcw--home: default timeout is 80% of the servo period
01:45 PM travis_farmer: ok JT, i haven't gotten that far yet, but will tomorrow
01:46 PM Tom_L: pcw--home, you happen to have had a chance to look into that card?
01:46 PM pcw--home: default error threshold is 10 in a row before you get "error finishing read"
01:47 PM pcw--home: Not yet, pretty busy but I will look at it today sometime
01:47 PM Tom_L: no rush, just curious
01:51 PM roycroft: i don't hang out on reddit, and was not familiar with that unusal tool thread
01:51 PM roycroft: er, specialized tool thread
01:51 PM roycroft: i am browsing it and so far i've found four tools posted there that i have and use
01:51 PM roycroft: now five
01:53 PM roycroft: i suspect many of the folks posting there just aren't that familiar with tools other than common household ones
02:31 PM CaptHindsight[m]: roycroft: xxcoder added the reddit machinists feed to LCNC on discord
02:32 PM CaptHindsight[m]: some interesting stuff shows up near daily
02:32 PM XXCoder: yeah. machinists, cnc, linuxcnc, github feed for linuxcnc, and gtyik whatever thats spelled
02:33 PM CaptHindsight[m]: and silly stuff https://www.reddit.com/r/Machinists/comments/vdwnrs/how_much_chuck_can_a_lathe_chuck_chuck/
02:41 PM roycroft: i have seen that kind of chuckage before
02:44 PM roycroft: i applied the last coat of shellac to the last set of drawers at lunch today
02:44 PM roycroft: so i should be able to install them right after work
02:47 PM roycroft: meanwhile, abom made his first chips with his precision-matthews lathe
02:48 PM roycroft: he found where the clutch slips and it stops cutting - taking a 0.400" cut on stainless steel
02:48 PM XXCoder: saw that yeah
02:48 PM XXCoder: his heavy cuts make me cringe a bit. lathe may be able to easily do it, but yeah lol
02:49 PM roycroft: heavy cuts are his schtick
02:53 PM JT-Shop: I almost got the wires neatly in place... maybe third time is a charm
02:53 PM roycroft: my 4k display is done with repair and was shipped back today - i should get it early next week
02:53 PM roycroft: then i can start work on my cnc router plans again
02:53 PM roycroft: if you cannot tame the wires there is little hope for this world
02:54 PM JT-Shop: it's not if but when
02:55 PM JT-Shop: couple of not so hot days coming up with lows in low 60's
03:22 PM CaptHindsight[m]: yeah just over 80 here today, tomorrow 70
03:23 PM Loetmichel: *giggle* forecast here in central germany is 100F for the weekend
03:25 PM XXCoder: 60f allllll week here except for today
03:25 PM XXCoder: today is 56f and fairly heavy rain
03:25 PM CaptHindsight[m]: yeah we just went through a week of that
03:25 PM CaptHindsight[m]: Loetmichel: ^^
03:25 PM JT-Shop: we have a slight chance for thunderstorms tonight
03:26 PM CaptHindsight[m]: electric bill more than doubled
03:26 PM * JT-Shop just noticed there is not enough clearance for the chain on the smallest sprocket on the cassette
03:28 PM JT-Shop: I need a Cassette Lockring Tool to remove the cassette and take the shim out and make a thicker one for the frame side
03:29 PM roguish[m]: well, hells bells. my Breco pulleys and belt just showed up..............
03:29 PM CaptHindsight[m]: bicycle?
03:30 PM travis_farmer: the family will be going down to the Maine coast for some lobster... i however will be eating buffalo chicken fingers (never liked lobster)
03:30 PM JT-Shop: that's the box ups lost?
03:30 PM roguish[m]: yup. guess they didn't loose it, just did not show any tracking.
03:30 PM roguish[m]: only said 'it shipped' with nothing following.
03:31 PM JT-Shop: fedex tracking has been wonky lately
03:31 PM roguish[m]: Breco was going to put in a claim to UPS, so I called Breco and let them know I got to package.
03:32 PM roguish[m]: now i have some machining to do. gotta make some new motor bracket to use the pulleys and get a 3:1 reduction on X axis
03:33 PM roguish[m]: have to bore the pulleys also to fit the Fenner trantorque bushings.
03:34 PM JT-Shop: nice
03:35 PM JT-Shop: I guess I'll take the back wheel/motor off again... tomorrow
03:35 PM roguish[m]: just put on a new encoder. 2500 ppm, to replace the old 1000ppm
03:35 PM JT-Shop: working on your mill?
03:35 PM roguish[m]: hoping this significantly helps the poor following error.
03:35 PM roguish[m]: yes
03:36 PM roguish[m]: get the motor up working at a better speed, with much higher resolution.
03:37 PM roguish[m]: JT-Shop: is your ebike a 'power assist' system?
03:37 PM roguish[m]: how do you control it?
03:38 PM travis_farmer: control is just an illusion
03:45 PM roguish[m]: frick. ATT just jacked my monthly cell charge by $10/month..... bastards.
03:46 PM travis_farmer: cooperate greed...
03:48 PM roguish[m]: every bit of it.
03:49 PM travis_farmer: same as gas prices...
03:49 PM roguish[m]: our gas is now over $7
03:50 PM XXCoder: yeah and gas factories is making less gas
03:50 PM travis_farmer: still under $6 here
03:51 PM roguish[m]: well, SF is happy. Warriors whupped the Celtics.
03:56 PM Loetmichel: roguish[m]: here in germany its about $8 per gallon of E10. and thats AFTER the 30% tax cut last month...
03:58 PM sliptonicBradCol: I upgraded my mill config to Bullseye/2.9 built from source. I run gmoccapy. After minor tweaks, I got the config to launch and everything works but VERY slow and laggy. Sometimes 20-30 seconds between clicking a GUI button and a response. Not a top of the line machine but it's been running an earlier build well enough. Known problem?
04:01 PM roguish[m]: Loetmichel: Europe has always be much higher. the higher prices here should be slowing people down on the highways, but it's not. still driving crazy fast, in monster sized cars and trucks.
04:03 PM Loetmichel: roguish[m]: ehm... no
04:04 PM Loetmichel: german cars are usually much smaller than US cars
04:04 PM Loetmichel: to be honest: i would like to have an (old) F150 or something like that. Because i like the looks. But i wouldnt dare to drive it at 200++kph.
04:05 PM Loetmichel: NOT if it has the original US suspension
04:06 PM Loetmichel: and yes, if i drive my BMW convertible at 140mph it DOES guzzle petrol like crazy. unlike when i drive it at 70mph.
04:06 PM Loetmichel: doesent mean i drive slow.. :)
04:07 PM roguish[m]: Loetmichel: i drive a MBZ E320. 2003.
04:07 PM Loetmichel: <- 318i E46 convertible. 2001
04:08 PM roguish[m]: before was an E420, before that an 290E, before that a VW Rabbit GTI
04:08 PM roguish[m]: 190E
04:08 PM roycroft: roguish: people would rather blame and complain than act sensible
04:08 PM roycroft: sensibly
04:09 PM roguish[m]: I've always thought we should have much higher fuel taxes, so as they're spent responsibly. lol
04:10 PM Loetmichel: roycroft: there are talks in germany to have a general 80mph tempolimit. I personally think thats about as probable as getting all americans to give up their gun rights.
04:10 PM roguish[m]: just not going to happen
04:10 PM Loetmichel: indeed
04:13 PM Loetmichel: well, i KNOW that my car has about 12mpg when i floor it (~135mph) and about 30mpg if i drive it at an average of 65mph... still sometimes its worth the money to have some legal fun.
04:13 PM Loetmichel: not always though, especially in heavy traffic
04:15 PM roycroft: the nice thing about evs is that not only do they pollute less than internal combustion engines, they generally have higher performance
04:15 PM roycroft: if you want go go from 0 to 100km/h in 4 seconds you're going to do that with a big electric motor
04:16 PM Loetmichel: roycroft: they are still not feasible for long range though
04:16 PM Loetmichel: not even the teslas.
04:16 PM roycroft: the problem in this country is that the oil companies have convinced consumers that evs have very poor performance, and need their batteries recharged every 17 blocks
04:16 PM roguish[m]: so what's FRAM company going to do? and BOSCH?
04:17 PM roycroft: some evs have a range of 600km now
04:17 PM roycroft: that's plenty
04:17 PM Loetmichel: <- has to drive 500km each weekend to see after his sister. with 3-4 hours in between. that will simply not work unless you have a supercharger directly at your destination
04:17 PM ZincBoy[CAON]066: How many trips do you do that are over 400km?
04:17 PM roguish[m]: I've driven a Tesla. strong as hell.
04:17 PM roycroft: especially since there are fast chargers that can fully recharge in 20 minutes
04:18 PM roycroft: but an ev is not the solution to every driving situation
04:18 PM Loetmichel: ZincBoy[CAON]066: one back and forth trip every weekend atm
04:18 PM roycroft: it can be the solution to the vast majority of needs
04:18 PM Loetmichel: roycroft: indeed. but not to all
04:18 PM roguish[m]: trains.........
04:19 PM roycroft: but again, the argument that is made here is "if it doesn't work for everything then it doesn't work at all"
04:19 PM Loetmichel: i would LIKE to make my BMW convertible a "hybrid" aka BEV with internal 20kw genset charger... will not happen thanks to german TÜV though
04:19 PM Loetmichel: just to expensive to get all that red tape cut through
04:19 PM ZincBoy[CAON]066: Still quite doable if you have a L2 charger at each end.
04:20 PM Loetmichel: ZincBoy[CAON]066: IF... thats not the case though
04:21 PM Loetmichel: and i know it would probably be cheaper than putting 60 liters (aka 120 eur atm) of E10 into the convertible each week.
04:22 PM roguish[m]: well, it's time for my bike ride. me powered.
04:22 PM ZincBoy[CAON]066: Yes, but this is getting more and more common. Electric vehicles are practical for the vast majority of drivers right now. The corner cases that get held up as examples can be solved by rentals or public transit.
04:22 PM Loetmichel: btw: the only tesla that i like the looks of is the Cybertruck. and i doubt that will come over the pond any time soon
04:22 PM roycroft: i would not want a tesla
04:22 PM roycroft: it's a fine car from what i've heard/read/seen
04:23 PM XXCoder: cybertruck: designed by kid after that kid gets angle ruler
04:23 PM roycroft: but i don't want to put any money in elon musk's pockets
04:23 PM Loetmichel: XXCoder: i LIKE that kind of design
04:23 PM ZincBoy[CAON]066: Fit and finish are 80s GM level though
04:23 PM XXCoder: lol
04:23 PM Loetmichel: ZincBoy[CAON]066: IF that.
04:23 PM ZincBoy[CAON]066: I was trying to be nice 🙂
04:24 PM Loetmichel: i have seen pictures of blank steel in a footwell of a model3.. no paint, new car, already rust patches under the floor mats
04:24 PM XXCoder: https://i.kym-cdn.com/photos/images/facebook/001/647/622/a37.jpg ;)
04:24 PM Loetmichel: XXCoder: i think most cars these days look simply "interchangeable"
04:25 PM ZincBoy[CAON]066: Guy at work has a model S and that thing has been in for repair more often than the guy with the Alfa.
04:25 PM Loetmichel: at least the cybertruck is "interesting"
04:25 PM XXCoder: yeah. honestly in general I dont care too much about looks
04:25 PM XXCoder: angled thing is bit odd though to me
04:25 PM Loetmichel: ZincBoy[CAON]066: OUCH. topping an alfa in repairs is hard work
04:26 PM ZincBoy[CAON]066: The cybertruck hits my cool car drawn in my middle school notebook look perfectly.
04:26 PM ZincBoy[CAON]066: Just don't know that I could bring myself to drive one.
04:27 PM Loetmichel: XXCoder: i have a wide range of tastes in cars. from the 60s firebird to the 80s Transam (KITT) to the cybertruck. But PLEAS not those "modern" streamlined bullcrap that looks the same regardless of manufacturer
04:27 PM XXCoder: loet its often because those makers sell each other body panel casts
04:27 PM XXCoder: im all A to B, reliably, and reasonable mpg
04:27 PM XXCoder: reasonable confort inside car
04:28 PM roguish[m]: roycroft: i've made almost $150k on Tesla stock. that's cash in the bank.
04:28 PM XXCoder: fancy
04:28 PM XXCoder: im losing massive money in stocks lol
04:28 PM XXCoder: $60 loss so far
04:29 PM XXCoder: out of $160
04:29 PM roguish[m]: know when to buy, know when to sell. the Warren Buffet way
04:30 PM roguish[m]: back in a while.
04:30 PM XXCoder: yup. honestly its fine if it all crashes, as I never gamble wth money I cant afford to lose
04:38 PM roycroft: i'm all for making money, but i won't invest in companies that i think are harmful, and while tesla's product is not harmful, it's ceo and principal owner is
04:39 PM XXCoder: I promise, it is not a penis :P https://imgur.com/Co6Oqj9.png
04:39 PM roycroft: my printer just crapped out
04:39 PM roycroft: i have to sort out what happened
04:40 PM roycroft: it started printing a box just fine, then about 1/3 of the way through the job the box started twisting around and getting smaller in the middle, then it finished fine
04:40 PM roycroft: but i had to trash it ,of course
04:40 PM roycroft: then i started another print ,and the first few layers were fine, but now it's not extruding anything
04:40 PM XXCoder: sounds like hotend jamming
04:40 PM roycroft: it's like the nozzle is clogged
04:41 PM XXCoder: do a cold pull
04:41 PM XXCoder: with nylon, if you have any
04:41 PM roycroft: i don't have any nylon
04:41 PM XXCoder: you probably can use trimmer line nylon
04:41 PM roycroft: but i can remove the nozzle and clean it
04:41 PM XXCoder: its not like youre printing with it
04:41 PM roycroft: i have some acupuncture needles that i got for cleaning nozzles, although this is a big, fat nozzle
04:41 PM roycroft: it doesn't need anything that small
04:42 PM roycroft: i just cancelled the print, and i'll head out in a few minutes an check on the nozzle
04:42 PM roycroft: it's been doing so well
04:42 PM roycroft: i was just about to swap in the second spool of that new filament i just got
04:44 PM roycroft: i'm still trying to figure out a good balance between printing a lot of boxes at a time so i don't have to tend to the printer as often and printing fewer so that i can deal with problems and waste less filament on failures
04:44 PM XXCoder: fun isnt it
04:44 PM roycroft: the results are nice
04:45 PM roycroft: and so far the results are worth the effort
04:47 PM XXCoder: thats nice when it happens yeah :)
06:07 PM perry_j1987: hey guys
06:07 PM perry_j1987: hows it going
06:07 PM XXCoder: not a lot. you?>
06:08 PM perry_j1987: trying to remember if there was any extra post processing i did on this lathe after exporting code
06:08 PM perry_j1987: its been about 6 months since i exported any code or touched the machines lol
06:14 PM XXCoder: ow heh. maybe need to mke notes
06:24 PM perry_j1987: bah bad signal out here at the shop today
06:29 PM roycroft: qwll i
06:29 PM roycroft: er, well i could not find anything wrong with the printer
06:30 PM roycroft: i just disassembled from the extrder to the hot end, cleaned everything (but nothing looked jammed/clogged), cut off a chunk of filament and reloaded
06:30 PM roycroft: i'll find out in a bit if it's working or not
06:30 PM roycroft: meanwhile i have four drawers to install and then i'm done installing drawers!
06:35 PM perry_j1987: what kind of printer?
06:49 PM roycroft: creality ender 5
06:49 PM roycroft: so far it is printing fine
06:49 PM roycroft: i suspect there was some kind of goober in the filament, which is why i reeled a bunch off before i fed it back in
06:51 PM perry_j1987: ah
07:19 PM roycroft: https://roycroft.us/New_Cabinets/25_All_Drawers_Installed.jpeg
07:19 PM roycroft: https://roycroft.us/New_Cabinets/26_Finished_Drawer_Pulls.jpeg
07:20 PM roycroft: i am pleased with how my drawer pulls are turning out, although i'm still not sure it was worth all the effort involved
07:20 PM XXCoder: its worth it
07:20 PM XXCoder: looks good
07:21 PM roycroft: the print is turning out fine too
07:21 PM roycroft: and thanks
07:21 PM roycroft: now to get back to making the drawer fronts, so the cabinets will look really good
07:22 PM roycroft: i wanted to make the countertop first, so i could index the drawer fronts off of it, but i need to work on that outdoors, and the weather is not cooperating
07:22 PM roycroft: so i'll just have to install the drawers and index the lip of the countertop off of them
07:22 PM roycroft: drawer fronts, rather
07:24 PM roycroft: and it looks like my print is done
07:24 PM roycroft: i'll go out and see if it's picassoesque or not
07:28 PM roycroft: the box is fine, so i'm back in business
07:32 PM XXCoder: nice
07:36 PM * xxcoder8265[m] uploaded an image: (742KiB) < https://libera.ems.host/_matrix/media/r0/download/jauriarts.org/skNyljgPXspiKzdIGxcvRoJw/unknown.png >
07:36 PM xxcoder8265[m]: testing that filament some more lol
07:36 PM xxcoder8265[m]: cant say why that plastic is special (its not visible)
08:18 PM CloudEvil: Is it highly radioactive?
08:19 PM XXCoder: maybe lol
08:21 PM XXCoder: cnc-cut records apparently https://hackaday.com/2022/06/17/wooden-you-like-to-hear-a-cnc-cut-phonograph-record/
08:30 PM t4nk_freenode: safety goggles highly recommended
08:38 PM roycroft: it would be rather ironic if i were to play one of those cnc cut records on my 100+ year old all mechanical/acoustic victrola
08:38 PM roycroft: and so much for printing for a while
08:39 PM XXCoder: finished all printing already?
08:39 PM roycroft: i should not have blamed the filament, because i just checked on a print and found the print claimed to be complete, but had only printed a few layers
08:39 PM roycroft: then i saw the meters and meters of filament that was tangled up behind the printer
08:39 PM -!- #linuxcnc mode set to +v by ChanServ
08:39 PM roycroft: the connector for the bowden tube to the hot end had broken
08:39 PM XXCoder: ouch heh
08:39 PM roycroft: that was almost certainly the problem all along
08:39 PM roycroft: it's like a $1 part, but it will take a week to get one
08:40 PM roycroft: i'll get several, and some spare nozzles and stuff, while i'm at it
08:40 PM XXCoder: yeah
08:40 PM roycroft: it's not worth placing an order for $1
08:40 PM XXCoder: cheaper than wait a week
08:40 PM roycroft: especially since shipping will probably cost $10
08:41 PM roycroft: this is actually ok
08:42 PM roycroft: while i've been happy to be printing boxes like crazy and get going on that part of my project, keeping the printer going while building my cabinets has become a little stressful, and tomorrow i have to start working on the country fair booth
08:42 PM roycroft: letting go of the printing for a week will be nice, even though it will put me behind schedule
08:43 PM XXCoder: yeah no reason to stress out
08:48 PM roycroft: so i can get hardened steel nozzles for about twice the cost of brass
08:48 PM roycroft: i'm not using abrasive filament, and don't plan on it any time soon
08:49 PM XXCoder: keep in mind you will need to set hotend to bit hotter
08:49 PM roycroft: i'm not sure it would be beneficial to get one
08:49 PM XXCoder: like 10c hotter for pla
08:49 PM roycroft: but going the other direction, they also have copper nozzles
08:49 PM XXCoder: TC you dont have to, but then it costs quite a it more
08:49 PM roycroft: that might be more useful for my application
08:50 PM roycroft: they would wear even faster than brass, but would conduct heat much better
08:50 PM XXCoder: dont know honestly, id just go for copper block and hardened steel nozzle
08:50 PM roycroft: perhaps i'll try one copper nozzle and see how that works
08:52 PM roycroft: my heater block is aluminium, and i don't see any other options for a volcano hot end
08:54 PM roycroft: and i was wrong - the parts are $2 each, not $1 each
08:55 PM roycroft: but shipping is $5 for the whole order, so that's fine
08:55 PM roycroft: i'm actually really good with this
08:56 PM roycroft: moving those fasteners into the drawers makes it a lot harder to finish building the cabinets, so now i can focus on the cabinets for a week
08:57 PM roycroft: i'm also starting to stock spares for the printer, which i should have done when i first bought it
08:57 PM XXCoder: yeah always good idea
09:13 PM roycroft: the importance of and need for sparing was deeply embedded in me when i worked for a telco
09:14 PM roycroft: the problem with the 3d printer is that when i got it i did not know what spares i would need
09:14 PM roycroft: now i have a pretty good sense of that
09:14 PM XXCoder: nothing like experence
09:14 PM roycroft: well, research helps
09:14 PM roycroft: and i'll admit that i did not do enough research on sparing when i bought the printer
09:15 PM roycroft: research does not replace experience, but it can help a lot
09:15 PM XXCoder: if you dont plan to have second printer, id print all printed parts
09:15 PM XXCoder: have them as spares
09:16 PM XXCoder: i dont bother to, since i have clone mk3s as well as my brothers mk3s+
09:16 PM roycroft: although i'm not sure it helps as much now as it used to - i run into a lot of resistence these days about sparing with clients and the like
09:17 PM XXCoder: im printing silly vase I designed in cad in couple minutes lol
09:17 PM XXCoder: it looks like normal polyagonic vase as long as you dont pay attention
09:19 PM roycroft: i would like to get another printer
09:19 PM roycroft: i just haven't decided what to get
09:20 PM XXCoder: i think you wanted larger volume right?
09:20 PM roycroft: that would be useful at times
09:20 PM XXCoder: i did wonder if its possible to make 3d printer "router" style
09:20 PM XXCoder: lower height but much larger area
09:20 PM roycroft: and there is an ender 5 with a bigger build plate
09:20 PM ZincBoy[CAON]066: I have seen it done
09:20 PM roycroft: i think it's the ender 5 plus
09:20 PM XXCoder: zinc yeah and theres belts too
09:21 PM ZincBoy[CAON]066: Problem usually is the acceleration you want is hard to do with bigger sizes.
09:21 PM ZincBoy[CAON]066: Usually it is practical when using larger nozzle sizes >1mm.
09:21 PM roycroft: i have a little laser that can mount on my printer
09:22 PM roycroft: if i got a second printer i could mount the laser on one of them, and leave it there as the default, and be able to print with the other
09:22 PM roycroft: and when i need to do a lot of printing, i could swap a filament squirter in for the laser
09:23 PM XXCoder: zinc maybe can get away with it if you use beefier steppers, like nama23
09:23 PM XXCoder: then make frame more rigid
09:23 PM roycroft: that's the real problem
09:23 PM roycroft: frame vibration
09:23 PM XXCoder: theres decouplers for that
09:23 PM ZincBoy[CAON]066: Maybe. You run into scaling problems with square cube
09:23 PM XXCoder: looks like couple ovals, offset to each other
09:24 PM ZincBoy[CAON]066: Frame stiffness is the other issue
09:24 PM roycroft: i got a set of decouplers, but i've been reading that installing them usually comes at the expense of resolution
09:24 PM roycroft: i.e. you get smoother prints, but coarser granularity
09:25 PM roycroft: i haven't installed mine yet
09:25 PM roycroft: i'll wait until this current project is done and then i'll experiment with them
09:25 PM XXCoder: I didnt care enough to mod mine that way so dunno
09:25 PM ZincBoy[CAON]066: The closest machines I have seen are pick&place machines for circuit boards. Large area and ridiculous acceleration. I have thought about converting an old one of those but don't have space for it.
09:26 PM roycroft: they were essentially free for me
09:26 PM roycroft: i was ordering some printer parts on amazon and needed to pad the order to get free shipping, so i added them
09:29 PM XXCoder: nice :)
09:29 PM XXCoder: what I DO recommand is go to improvement shop and buy paver stone
09:30 PM XXCoder: large enough to place your printer on
09:30 PM XXCoder: and rubber mat to put under that
09:30 PM XXCoder: I used baby crawl mats from aliexpress. 10 sheets for 11 usd, shipped
09:31 PM roycroft: i wonder if a piece of stall mat would work
09:31 PM roycroft: i have plenty spare stall mats
09:31 PM XXCoder: dunno, it should eat vibrations and motion
09:31 PM roycroft: they do that pretty well
09:31 PM XXCoder: it should make printer quitr a lot quieter, and improve qualty of print by a little bit
09:31 PM roycroft: they're the thick rubber mats used in horse stalls
09:32 PM XXCoder: latter is why I bother.
09:32 PM ZincBoy[CAON]066: Stall mats might be a bit too high a density.
09:32 PM roycroft: i use them in my shop as anti-fatigue mats
09:32 PM roycroft: they are pretty dense
09:32 PM roycroft: they cushion me well, but i weigh a lot more than my 3d printer
09:33 PM XXCoder: https://www.aliexpress.com/item/2255801064508297.html
09:33 PM XXCoder: oh it dont exist a sec
09:33 PM ZincBoy[CAON]066: They would help with higher frequencies but the interlocking foam floor tiles might be a better match.
09:33 PM XXCoder: https://www.aliexpress.com/item/3256804147240779.html
09:34 PM XXCoder: it not only has foam, it also have "rug" which would eat even more vibration
09:34 PM XXCoder: I used 2 each paver stone
09:34 PM roycroft: right now, and for the next several months, my only print job is making boxes to store fasteners and other hardware in my shop
09:35 PM roycroft: so print quality for the next several months is not my highest priority
09:35 PM XXCoder: yeah im sharing link to keep it in list in case your mat isnt enough damping
09:37 PM roycroft: those locking mats from harbor freight are pretty spongy
09:37 PM roycroft: and very cheap
09:38 PM roycroft: i'm not interested in them at all as anti-fatigue mats
09:38 PM roycroft: but they might be ok for dampening a 3d printer
09:38 PM XXCoder: yeah
09:39 PM roycroft: https://www.harborfreight.com/4-piece-anti-fatigue-foam-mat-set-94635.html
09:39 PM XXCoder: as long as it dont literally just flatten to solid, it would work
09:39 PM XXCoder: and not too solid
09:39 PM XXCoder: very cheap allright
09:40 PM roycroft: and they keep sending me 25% off coupons
09:40 PM XXCoder: tthat one can be cut into bunch of printers mats lol
09:41 PM roycroft: it's four pieces
09:41 PM roycroft: each piece is probably only big enough for one printer (with a fair amount of trimming)
09:42 PM roycroft: so you should be able to dampen 4 printers easily
09:42 PM roycroft: without having to cut squares that overlap the pieces
09:44 PM roycroft: the problem with those mats is that they smell like china
09:44 PM ZincBoy[CAON]066: I have seen those harbor freight mats recommended for 3d printer damping.
09:44 PM Tom_L: wonder if anyone has made a printer with servos
09:44 PM ZincBoy[CAON]066: Stratasys 🙂
