01:05 AM Bleeptech: Oops! Wrong power plug... LOL
01:19 AM Deejay: moin
01:49 AM rs[m]: Bleeptech: esc should be equivalent to the "stop" button (octogon with X, next to cycle start)
01:50 AM rs[m]: it's possible gmoccapy doesn't show that butten when homing
02:19 AM Bleeptech: rs[m]: Yeah, I finally tracked down a keyboard shortcuts list. Now I trying to figure out why the whole section for shortcuts is greyed out in the settings.
03:39 AM Loetmichel: *snicker* german problems. Project manager explaining the foreign coworker some work procedure in english... Three other workers in unison: "hey, proper 'th' is on backorder?" ... we have WAY to much fun on the job :D
03:40 AM Loetmichel: +pronunciation
03:41 AM Loetmichel: "Sis is se CPU, it is installed sis way..." :)

04:19 AM veegee: nominal sizes are so confucius
04:20 AM veegee: As much as I hate NPT fittings, at least they have large inside diameters for high flow
04:21 AM veegee: 1/4" JIC has a 0.172" inside diameter what the hell
04:22 AM veegee: I get that it has a 6000 PSI pressure rating and needs the wall thickness :(
04:23 AM veegee: I think this is why Mario quit plumbing and went on to chase princesses and ride dinosaurs instead
04:24 AM enleth: veegee: get someone who doesn't know, hand them a 1/2" NPT pipe and calipers and ask them to find the 1/2" in there, then watch their expression
04:24 AM enleth: it's priceless
04:24 AM veegee: Yeah I know what you mean lol
04:24 AM veegee: It throws me off sometimes too
04:24 AM veegee: 1/2" FNPT-FNPT couplers look huge
04:25 AM veegee: also NPT and NPT-F are two different things
04:26 AM veegee: I do like the way the conical inner seat on the MNPT-F seals against the FNP parallel swivel
04:26 AM veegee: and properly machined NPT threads are not that bad if you follow the turns-past-finger-tight
04:28 AM veegee: those FNPT swivels are cheaper than pipe unions too. The only downside is they're meant for hydraulics and have the same vastly reduced inside diameter which is bad for air flow
04:28 AM veegee: Maybe I'm overthinking it. I need to do some calculations on pressure drop across the fitting. I just don't want the fitting inside dimension to be smaller than the hose inside diameter. I guess you can't avoid the hose barb anyway so what's the point worrying about the fitting?
04:29 AM veegee: My mind naturally likes to overthink things like this. Mostly why the pandemic and social isolation has had zero impact on me

04:30 AM enleth: veegee: couplers cause restriction but they're short
04:30 AM veegee: That's true, but so is the tip of a pressure washer
04:31 AM veegee: and look how much flow restriction that causes
04:31 AM veegee: (when the pump is off and the only pressure is the water supply line pressure)
04:31 AM enleth: but it's a pinhole compared to couplings
04:32 AM veegee: that's true, so I guess I have to do the math to figure out the pressure drop and get some hard numbers to put my mind at east
04:32 AM veegee: ease*
04:32 AM veegee: Or just test it. I have plenty of pressure gauges and an expensive air flow meter borrowed from a friend
04:33 AM enleth: definitely test it if you're inclined to know for sure
04:34 AM veegee: https://www.princessauto.com/en/nptm-x-nptf-swivel-couplers/product/PA1000000479?skuId=1291970
04:34 AM veegee: Look how insanely cheap a 1" NPT swivel coupler is
04:34 AM veegee: local plumbing store prices are 5x that for a 1" pipe union
04:35 AM veegee: and you can bet your ass the hydraulic swivel is built a million times better. Rated for 3,000 psi
04:36 AM veegee: And whatever steel and plating they're made of is much more corrosion resistant and doesn't flake. The galvanized unions flake off zinc like crazy
04:36 AM veegee: The princess auto hydraulics department is proof that god exists and god is good
04:40 AM veegee: I'm inclined to make my own brass unions because the prices on those is insane
04:41 AM veegee: It's a glorified flare fitting
05:06 AM veegee: https://nolimitdronez.com/mavic-info I'm so glad I kept my mavic original.
05:07 AM veegee: Also have the mavic 2 pro, but they haven't been able to fully hack it yet. Contemplating getting an Inspire 2 for its speed
05:27 AM jymmmm: Good morning
05:41 AM JT-Cave: morning
08:33 AM Loetmichel: hmm... just staggered over the "something new, something old, something borrowed, something blue" tradition at weddings... cue googling down a rabbit hole. Interesting that that is even a tradition in germany. thought it to be brithis/american only. TIL... :D
08:36 AM Loetmichel: ... but now that i recall my wedding: wife did follow that tradition. :)

10:58 AM roycroft: it's my friday, and not a day too soon
11:42 AM JT-Cave: yea lunch minute
11:59 AM JT-Cave: time to make chips
01:53 PM CaptHindsight: for the Rpi users http://linuxgizmos.com/20-add-on-provides-real-time-clock-for-the-raspberry-pi/
01:58 PM Tom_L: you see what jepler did with it?
01:58 PM Tom_L: dev channel
01:59 PM CaptHindsight: plug in a PCIe card?
02:02 PM CaptHindsight: https://forum.linuxcnc.org/18-computer/39037-linuxcnc-orange-pi?start=120#207379
02:02 PM Rab: Jeez, how is abstracting the timestamp through USB better than using the Pi's native I2C? Doesn't sound like the timestamps are coming through in real time.
02:03 PM CaptHindsight: just with 10mS jitter :)
02:03 PM CaptHindsight: 100mS
02:03 PM CaptHindsight: how real time do you need your clock?
02:04 PM Rab: Of course there are versions which do that. https://wiki.seeedstudio.com/High_Accuracy_Pi_RTC-DS3231/
02:09 PM Rab: That one has a square wave output which can be configured for 1Hz-8.192kHz.
02:13 PM CaptHindsight: not sure what all the fuss is over the Rpi since several other low cost ARM boards will be able to software step to the hundreds of KHz or plug into a Mesa FPGA
02:18 PM CaptHindsight: the Rpi Pico should work with Remora
02:19 PM CaptHindsight: GPUs on a Raspberry Pi Compute Module 4! https://www.youtube.com/watch?v=ikpgZu6kLKE
02:20 PM CaptHindsight: not sure why he just doesn't ask in #radeon
02:22 PM aaroncnc: CaptHindsight I liked it as it was my first foray into linux and is a very well documented platform. And if the project fails i can use is for other things.
02:24 PM CaptHindsight: aaroncnc: it won't fail, too much interest
02:25 PM CaptHindsight: the problem is the first platform chosen is just difficult to come by for the time being
02:26 PM CaptHindsight: smoothie II uses a different micro, not sure what the availability of that is yet
02:26 PM CaptHindsight: but they keep on making their boards without any protection on the IO's
02:26 PM aaroncnc: you talking about ability to get a RPI4 or a skr1.4?
02:27 PM CaptHindsight: no
02:28 PM CaptHindsight: the RPi4 has too high a latency for fast software stepping
02:29 PM CaptHindsight: many microcontrollers may be used with remora to generate fast steps
02:30 PM CaptHindsight: we just need to pick some that are readily available due to the pandemic
02:30 PM aaroncnc: maybe i am spoiled with having a microcenter near me. they always seem to have what i need in stock (besides gpu's...)
02:31 PM CaptHindsight: for onesy twosey
02:31 PM CaptHindsight: doesn't help if lots of users need board
02:31 PM CaptHindsight: s
02:31 PM roycroft: the problem is that almost all microchips are in short supply due the pandemic and, in the usa, due to the previous regime's insane tariffs
02:32 PM aaroncnc: even the car company's cant get the chips they need
02:32 PM roycroft: it's affecting virtually everything
02:32 PM roycroft: right
02:32 PM roycroft: or washing machine makers
02:33 PM CaptHindsight: I have found lots of low cost devs boards in stock in the 100's but then you still need some buffering and protection on the IO's
02:33 PM roycroft: apple are predicting a $4-$5 billion decrease in revenue this coming year due to the chip shortage
02:33 PM CaptHindsight: so it becomes a stack of at least three boards
02:35 PM CaptHindsight: $5 H3 on a board with everything on board might be made for ~$50 + profit margin
02:35 PM aaroncnc: I was thinking what you said a dayu or so ago about protection, i remember i have a few parallel port bobs that i could use for protection but you are right that makes a 3 board chain RPI4->SKR1.4->protection board.
02:35 PM CaptHindsight: 3-4 axis stepping
02:36 PM CaptHindsight: they don't care about IO protection when used with a CNC glue gun
02:37 PM CaptHindsight: but they do "market" the board for small CNC machines
02:37 PM aaroncnc: but if there was enough interest one could build a hat for the RPI that combined the skr1.4 and protection into one. with more focus on cnc.
02:38 PM CaptHindsight: well there already is the Mesa board for the Rpi
02:38 PM aaroncnc: the 7C81 right?
02:38 PM CaptHindsight: think that is the number
02:43 PM aaroncnc: maybe a cost thing? that board is 90$ plus the cost for another breakout board right?
02:44 PM CaptHindsight: http://store.mesanet.com/index.php?route=product/product&product_id=338
02:46 PM CaptHindsight: http://store.mesanet.com/index.php?route=product/product&path=83_85&product_id=345&sort=p.model&order=DESC&limit=100
02:46 PM aaroncnc: 250$ for a rpi board ouch.
02:46 PM CaptHindsight: plus the Rpi $40-60
02:47 PM CaptHindsight: give someone like Olimex a H3 board design with protected IO
02:48 PM CaptHindsight: they already make H3 boards
02:48 PM CaptHindsight: and they live on razor thin margins
02:55 PM aaroncnc: The other draw of the RPI and remora is i do come from a 3d printer background. i have built many with my largest being a rebrained Stratasys FDM 2000. alot of people use RPI product's to run octoprint so they at least know the products and picking a 3d printer main board that they may have already used thats normally very cheap helps some take the
02:55 PM aaroncnc: jump. Also allows focus to go purely into software dev and not having to go into board design and testing and dealing the physical production. help keeping the cost down and speed up.
02:58 PM CaptHindsight: the H3 can also run Octoprint
02:59 PM CaptHindsight: and an all in one H3 board would just leave software mods to the those users
03:00 PM CaptHindsight: think of a Smoothie with an Rpi built in
03:00 PM CaptHindsight: Arthur could have just done this but he is Arthur
03:02 PM roycroft: and he is king
03:03 PM roycroft: he would not do it
03:03 PM roycroft: he would have it done
03:04 PM CaptHindsight: the other end of the spectrum from FDM printers is CNC machines that cost 10's or 100's of thousands of $
03:05 PM CaptHindsight: shaving $100 off the cost of the electronics is only a concern for the most obsessive of money hoarders
03:07 PM aaroncnc: CaptHindsight, thats not always the case. but in my case i happen to live in an area with lots of those machines some left in the rain and sold as scrap. i am on cnc mill 2. and as soon as i can expand my garage i might be picking my first 3 phase machine and i wont pay more than maybe 2k for it.
03:08 PM aaroncnc: They need alot of work, but thats my favorite part once they are working i start looking for something else.
03:10 PM CaptHindsight: $2500 delivered https://imgur.com/ey5VtXu
03:12 PM CaptHindsight: IMHO Mesa and an Industrial PC have the reliable end of things well covered
03:13 PM Roguish: afternoon. does anyone know what 'push-pull' means for encoder output?
03:13 PM Roguish: in really stupid simple terms...
03:13 PM CaptHindsight: there is some room on the cheap end of things for near 0 profit margin boards for cnc glue guns
03:14 PM CaptHindsight: Roguish: likely https://en.wikipedia.org/wiki/Push%E2%80%93pull_output
03:15 PM CaptHindsight: so TTL level totem pole
03:16 PM Roguish: CaptHindsight, so no problem with interfacing to Mesa boards..???
03:16 PM CaptHindsight: aaroncnc: I think the smoothie avoids any LCNC compatibility
03:17 PM CaptHindsight: aaroncnc: it just happens that remora makes it work
03:17 PM aaroncnc: CaptHindsight have you tried Remora yet?
03:17 PM CaptHindsight: aaroncnc: Smoothie II could have been an imx8 or H3 design and the price would be nearly the same, or lower with the H3
03:18 PM CaptHindsight: aaroncnc: only in a SIM, I don't have any LPC1768 boards, will likely port to an STM32
03:20 PM CaptHindsight: Roguish: I don't see a problem
03:21 PM aaroncnc: CaptHindsight i have a few of those discovery boards kicking around in a drawer.  seems like you have an aversion of the LPC boards.
03:21 PM CaptHindsight: not really, just smoothie
03:22 PM CaptHindsight: the LPC17xx devices cost more than an H3
03:23 PM CaptHindsight: well you have to add the cost of RAM and ROM to an H3 but it's under $6 for the H3

03:27 PM aaroncnc: The site is temporarily unavailable. Please contact your local branch for immediate assistance...
03:28 PM CaptHindsight: both links work here, huh
03:29 PM CaptHindsight: https://www.olimex.com/Products/Components/IC/H3/ after they markup
03:29 PM CaptHindsight: they used to have an H3 board so it wouldn't be much effort to spin a new board with some IO's for steppers and encoders
03:30 PM aaroncnc: seems the lpc17 board go for 3x that price.
03:30 PM aaroncnc: chips^
03:31 PM CaptHindsight: https://olimex.wordpress.com/2016/02/03/h3-olinuxino-nano-is-only-50x50-mm-but-has-everything-one-computer-must-have/
03:31 PM CaptHindsight: the design is available in Eagle format
03:31 PM CaptHindsight: I could hold my nose and make a new one
03:32 PM Roguish: CaptHindsight, just chatted with PCW. it's all cool.
03:36 PM CaptHindsight: aaroncnc: would 3d printer "makers" whine about a smoothie board that also runs LCNC, has HDMI 4K GUI support and GB Ethernet?
03:36 PM CaptHindsight: that costs about the same
03:37 PM CaptHindsight: and runs LCNC or GRBL
03:40 PM aaroncnc: CaptHindsight the honest truth is the cost and plug and play. so costs about the same as? i know many that see the Duet boards as to expensive.
03:41 PM CaptHindsight: or machinekit
03:43 PM CaptHindsight: choices of boards for FDM printers seem to revolve around some pathology vs reason
03:43 PM CaptHindsight: various tribes around firmware
03:46 PM CaptHindsight: it's even worse with SLA/LCD resin printers, they mostly tolerate closed source
03:46 PM CaptHindsight: as long as it's cheap
03:47 PM aaroncnc: when i started i only used the ramps 1.4 boards with mega 2560 clones from microcenter. the 2560 cost 10$ and the ramps 1.4 were around 15-20$. It took some time for me to move past my safe zone and try other boards. But yes price and plug in play seem to rule all. the race to the bottom.
03:49 PM buzzmarshall: most 3d makers are mostly freeloaders with little incentive to move into that costs them money thus reducing their margins
03:49 PM buzzmarshall: lol
03:49 PM buzzmarshall: CaptHindsight i agree
03:50 PM buzzmarshall: lets not forget the original marlin and stuff was really nothing more then pilfering grbl's opensources and addin the hot end and a few other things
03:50 PM buzzmarshall: which the atmels barely can handle
03:51 PM buzzmarshall: anyone with a few machine shop tools and can make and sell 3d printers and leverage off the existing electronics
03:52 PM buzzmarshall: the scene was basically stuck in that mode till a few developed alternatives which everyone once again took and are kinda still sitting at
03:53 PM buzzmarshall: personally i hate smoothies and any of those other boards that embed the motor drivers on board as there to expensive for most to troubleshoot and repair
03:54 PM buzzmarshall: and the ones building those types of boards know that as its part of their revenue streams
03:54 PM buzzmarshall: toss the board over a bad driver and just buy a new one
03:54 PM buzzmarshall: i hate that kinda thinking
03:54 PM buzzmarshall: lol
03:55 PM CaptHindsight: yeah, well if you met the people behind them you would be reassured in your thinking
03:55 PM buzzmarshall: lol
03:55 PM CaptHindsight: yet they poo poo makerbot for doing what they wish they could have done
03:56 PM buzzmarshall: your right tho as there are better things out there with better future use and adaptablity
03:56 PM buzzmarshall: ya that parts not right for sure
03:57 PM buzzmarshall: i always kinda just looked at the better upper makers being more creative as one thing but most of the other cheaper guys are just a bunch of moochers
03:58 PM CaptHindsight: https://www.nanodlp.com/ not open source but runs on the Rpi's
03:59 PM CaptHindsight: https://www.chitubox.com/en not open software or hardware but uses STM32
04:00 PM CaptHindsight: https://chitusystems.com/product/chitu-l-v3/
04:01 PM CaptHindsight: stm32F407 like the discovery board
04:04 PM CaptHindsight: kevin did write Klipper https://github.com/KevinOConnor/klipper
04:04 PM buzzmarshall: ya i could see the stm32's being a good choice as well as ti stuff as at least in most ways the makers are open about most info required to keep boards based around them open for future mods
04:04 PM CaptHindsight: with readable source
04:04 PM buzzmarshall: thats the problem with things like the rsp and even allwinner rk and aml
04:04 PM CaptHindsight: vs dyslexic Marlin
04:05 PM buzzmarshall: their all great boards in their own way but to many things info wise are still kept private
04:05 PM buzzmarshall: ya marlin and all those derivitives kinda kill me
04:05 PM buzzmarshall: served their purpose i quess for the initial freebie makers
04:07 PM CaptHindsight: bbl , nice out today here
04:07 PM buzzmarshall: k... enjoy the weather

05:39 PM Tom_L: what is considered a high helix endmill?
05:39 PM Tom_L: what twist angle?
06:37 PM JT-Shop: the pitch
06:37 PM JT-Shop: of the helix
06:37 PM Tom_L: right, but what's considered hith
06:38 PM Tom_L: high
06:41 PM Tom_L: acording to google: A higher helix angle, usually 40° or more, will wrap around the tool “faster,” while a “slower” helix angle is usually less than 40°
06:41 PM Tom_L: i was looking at those 60° ones from lakeshore
06:42 PM JT-Shop: that's above my pay grade lol
06:43 PM Tom_L: chip evacuation is better
06:43 PM Tom_L: better surface finish
06:43 PM JT-Shop: for deep slotting?
06:43 PM Tom_L: or pockets etc
06:43 PM JT-Shop: less recutting chips?
06:43 PM Tom_L: also, they have some that have a 'nick' in the edge which is used as a chip breaker
06:43 PM Tom_L: yes
06:44 PM Tom_L: cutting chips is very bad for the cutter

06:55 PM XXCoder: yay new montiors and video card
06:56 PM XXCoder: i tested some shitty low contrast sites and i can read em now
06:56 PM XXCoder: artist type screens, so good color setup
07:00 PM JT-Cave: yeah stupid web programmers think low contrast is the way to go must be democrats I guess
07:04 PM Tom_L: so you can't see the fine print?
07:04 PM veegee: So the old Russian dude gave me this for free: https://www.ebay.com/itm/VICKERS-HYDRAULIC-PISTON-PUMP-PVB5-LSY-20-C-11-/312098692820
07:04 PM veegee: complete with a set of new pistons and rebuild kit
07:05 PM XXCoder: jt what
07:05 PM veegee: Closed center hydraulics, here I come
07:05 PM XXCoder: JT-Cave: honestly that is very strange offhand comment for you
07:06 PM XXCoder: plus in my experence so far, republican news sites is far more often low contrast than democrat sites.
07:07 PM Tom_L: when the embers on a fire die down ya just gotta stir it a bit :)
07:08 PM JT-Cave: lol
07:09 PM XXCoder: hah
07:09 PM XXCoder: was there political discusssion recently?
07:10 PM XXCoder: i left for while to upgrade video card and montiors
07:10 PM JavaBean: oh hey, just the troll i wanted to see
07:10 PM JavaBean: check it out, dude!!! https://www.youtube.com/watch?v=RIiiGReUZ3A
07:11 PM JT-Cave: the chickens have been having quite a debate on who is the biggest butt picker of all
07:12 PM XXCoder: im meh on solar roads
07:12 PM JavaBean: i think he does a good job explaining "why they are a bad idea" in general
07:13 PM XXCoder: yeah watched it before
07:13 PM JavaBean: and why would they debate on who the "biggest butt picker of all" is??? are they competing or something? i figured they all just did it
07:14 PM JavaBean: and xxc... that is a new video. atleast posted today(my time)
07:15 PM XXCoder: hmm i must have rememebred a similiar video
07:15 PM XXCoder: it was rather critical with solar roads, and i agree
07:15 PM XXCoder: im all for ecogical power generation, but high abuse surface as solar?
07:15 PM JavaBean: all things considered, it is possible... he has like 100 other videos bashing the topic
07:16 PM XXCoder: wow not sued to quality colors
07:16 PM XXCoder: used
07:16 PM XXCoder: those montiors is made for artists in mind
07:17 PM XXCoder: so high color precision
07:17 PM JavaBean: do you have them set for color accuracy?? or are they still in "show room floor" mode?
07:17 PM XXCoder: this montiors is adjusted for best colors etc out from box.
07:18 PM XXCoder: it even have test results sheet with it lol
07:18 PM XXCoder: it took me quite a lot of time to find store that have two,
07:18 PM XXCoder: its 99% out of stock. its that popular
07:18 PM XXCoder: and basically 1%, only one left lol
07:19 PM JavaBean: well, congrats... hopefully in YOUR case those "test results sheets" aren't just photocopies of a different monitors results
07:19 PM XXCoder: lol good question. in very least i already tested results on sites with awful contrast
07:19 PM XXCoder: like thingverse comments (must be republican site? ;) )
07:21 PM JT-Cave: lol
07:22 PM JT-Cave: looks like a nice couple of days here... Bluewing battery should arrive tomorrow after 3 months...
07:22 PM XXCoder: on completely unrelated note, i cant wait to get that kickstarter spray can
07:22 PM Tom_L: was ~75 here
07:22 PM XXCoder: its to turn plain paint into spray can. awesome! i also plan to use it with empty bottle as air can! so i can clean out my computer dust
07:23 PM JT-Cave: supposed to be 75 and sunny tomorrow
07:23 PM Tom_L: better call in sick
07:23 PM JavaBean: got to about 52f here... we need this rain at this slow of a pace... but damn its "cold" out, all the humidity and wind just makes it feel worse
07:23 PM XXCoder: at just 75f?
07:23 PM JT-Cave: what if the boss don't answer the phone?
07:23 PM XXCoder: ah play hooky
07:23 PM Tom_L: he's probably out fishin
07:24 PM JavaBean: atleast say he is out "Phishing"...
07:24 PM JT-Cave: then I'm going for a ride with the wife after UPS comes by
07:24 PM JT-Cave: screw work
07:24 PM XXCoder: :)
07:24 PM JavaBean: is UPS delivering your UPS?? or is it coming in via UPS?
07:25 PM JT-Cave: ups?
07:25 PM XXCoder: ups being delivered by ups indeed. that'd be perfect
07:25 PM JavaBean: oh, is it a battery battery? not a UPS battery?
07:26 PM XXCoder: just keepe out for assult and battery
07:26 PM XXCoder: *look out for
07:26 PM Tom_L: my kid's 2nd shift counterpart scrapped ~300k worth of parts and tried to blame him. luckily he's got all the paperwork showing who did what and it warn't him
07:26 PM JT-Cave: how did ups get into the conversation for a Yuasa GYZ20L?
07:26 PM XXCoder: 300k OUCH
07:27 PM Tom_L: they're a bunch of lazy asses on 2nd
07:27 PM JT-Cave: yeah CYA always
07:27 PM JavaBean: sorry sorry, been having battery = ups conversations all day... my brian hurts right now
07:27 PM JT-Cave: have a favorite beverage on me then
07:27 PM XXCoder: yay iced water. thanks!
07:28 PM JT-Cave: with lemon?
07:28 PM * JavaBean grabs a screwdriver... thanks JT-Cave
07:28 PM XXCoder: no lemon
07:28 PM JT-Cave: maybe some crushed mint?
07:29 PM XXCoder: lol no way
07:29 PM JT-Cave: a string of garlic around your neck while you drink it?
07:29 PM XXCoder: yeah them vampires is annoying
07:30 PM JavaBean: i don't recommend "garlic infused" water
07:30 PM JT-Cave: LOL
07:30 PM XXCoder: i would never drink almond milk
07:30 PM Tom_L: they had a meeting about it last night lasting ~1.5 hrs
07:31 PM XXCoder: almonds cannot liquidify. so it is actually just water infused with almonds
07:31 PM XXCoder: java that'd be perfect for giving to vampires.
07:31 PM JavaBean: like "skim milk"... someone lieing so they can sell some bullshit
07:31 PM XXCoder: remove stuff, then sell it for more
07:31 PM Tom_L: the merican way
07:33 PM JT-Cave: I got a room in north Houston for two nights and the tax was $100!
07:34 PM JavaBean: someone tried to slip me some of that "almond milk"... it tasted like a chemistry set, so i imagine that with enough chemicals they could manage to liquify almonds
07:34 PM JavaBean: just the tax was $100??
07:37 PM XXCoder: java lol but mah what they do is just crush alnonds a lot
07:38 PM XXCoder: almonds is also very bad for envorment, it needs very hot and warm, and lots of water to grow. usa dont have a place like that. closest thing to that is calfornia
07:38 PM XXCoder: and they just feed a lot of water in place of rain
07:40 PM Tom_L: i like the beach at Galveston
07:41 PM Tom_L: gonna make it that far S?
07:47 PM -!- #linuxcnc mode set to +v by ChanServ
08:07 PM XXCoder: ouch. advistory from usa to leave india now
08:08 PM Tom_L: it's bad over there
08:09 PM XXCoder: yeah i'd have already have left before warning

09:43 PM Tom_L: roycroft, https://www.sandvik.coromant.com/en-us/knowledge/general-turning/pages/how-to-choose-correct-turning-insert.aspx
09:43 PM Tom_L: thought you might get something from that
09:46 PM Tom_L: http://www.mitsubishicarbide.com/en/technical_information/tec_turning_tools/tec_turning_insert/tec_turning_guide/tec_turning_identification
09:47 PM Tom_L: i would imagine the id system is fairly standard across brands
10:02 PM roycroft: thanks
11:07 PM pink_vampire: hello
11:07 PM XXCoder: yo
11:08 PM enleth: do you know the trick to not wrecking this style of holder when the insert breaks? https://www.sandvik.coromant.com/en-gb/products/pages/productdetails.aspx?c=rf123g079-16b
11:08 PM enleth: by now, I have two that got the heel under the insert chewed up when the insert cracked
11:09 PM XXCoder: theres no overhand?
11:09 PM XXCoder: *pverhang
11:09 PM XXCoder: -p +o
11:09 PM enleth: as far as I can tell, the piece of insert got pulled into the space between workpiece and holder heel
11:09 PM enleth: and something had to give
11:10 PM pink_vampire: I finished my home made pulley!
11:10 PM enleth: this happened twice so I assume it'll happen again
11:10 PM enleth: but those holders aren't cheap
11:10 PM XXCoder: pink yeah? whats it for?
11:10 PM XXCoder: enl I wonder if you could cop front off, then make it screw mounted
11:10 PM pink_vampire: https://i.imgur.com/0c8yNvN.png
11:10 PM XXCoder: so you could replace tip if broke again
11:11 PM pink_vampire: XXCoder: it is for my lathe
11:11 PM XXCoder: looks like cnc machine pulley
11:11 PM enleth: XXCoder: there is a 3-piece holder type for slightly different cutoff inserts and I'll be switching to that
11:11 PM XXCoder: yeah figured that LOL hows lathe? last i heard you barely started fixing it
11:11 PM pink_vampire: lol, it is cnc machined
11:11 PM XXCoder: nice enl
11:11 PM enleth: but I'm stull curious how people managed to use that style
11:11 PM enleth: *still
11:12 PM XXCoder: good question as I dont use lathe. i wonder if that means feed was too high for that holder type
11:12 PM XXCoder: as if feed was slower, it would break off without chunk chewing holder
11:12 PM XXCoder: theorically anyway
11:13 PM pink_vampire: my lathe is in perfect working condition
11:13 PM pink_vampire: other then that I'm trying to figure out a way to go back in linux cnc.
11:13 PM XXCoder: go back as in what?
11:13 PM pink_vampire: to run the code in reverse
11:14 PM XXCoder: oh hmm dunno dont think i ever seen anything like running backwards
11:14 PM pink_vampire: like if you paused the machine, to make it go backward
11:17 PM XXCoder: yeah dont know of such thing
11:33 PM gigasu_shida is now known as gigas_cedar
11:45 PM Bleep-CNC: pink_vampire: AFAIK If you want a 'REWIND' you'd need to ask for a feature request or write a module for it yourself.
11:45 PM XXCoder: yo
11:46 PM Bleep-CNC: Yo-Yo.
11:46 PM XXCoder: lo-lo
11:46 PM * Bleep-CNC awtches the Z axis og up and down...
11:46 PM pcw_home: There is reverse run in LinuxCNC
11:48 PM XXCoder: pcw oh really? didnt know it existed
11:51 PM * Bleep-CNC is still learnig the extended bits of linuxcnc after a crash course in rebuildind and tuning an ancient CNC router.
11:53 PM Bleep-CNC: XXCoder: Did a run with a pattern from F-Engrave. Copy of a road sign at 5" scale. It cut it all without a hitch and was within .0.010 after jogging all over hell running the 3 rows of text at a 45 degree angle.
11:54 PM XXCoder: not bad, with untested tool and such
11:55 PM Bleep-CNC: XXCoder: 60 degree 1/4"Dremel cutter in a 1/4">1/8" collet. I figured it's give me fine lines with a shallow cut and at $10/pair they're cheap enough to pop a couple.
11:56 PM XXCoder: not bad yeah
11:56 PM XXCoder: you in sign making business?
11:57 PM Bleep-CNC: XXCoder: Nope, There's just one they use here I find funny as hell and I wanted a small copy for the shop wall.
11:57 PM XXCoder: lol ok
11:58 PM XXCoder: man I want to run my cnc router
11:58 PM XXCoder: but no aww
11:58 PM Bleep-CNC: And it's a real torture test for accuracy with the way F-Engrave plots paths. With the text at a 45 it's forced to do some real work to keep the lines straight.
