01:48 AM randy: morning
01:54 AM Deejay: moin
04:48 AM Loetmichel: grrr... why me all the time? just got a call from the mechanic. His "differential-refurbisher" looked into my BMWs diff: "Yeah, no. No way to repair THAT. get a new one!"... He said only shards of the gears remained. And the next 1400eur down the drain... :(
04:49 AM XXCoder: ouch
05:04 AM Tom_L: morning
05:04 AM Tom_L: wind chill -5°F
05:49 AM randy: Loetmichel: well, there's a positive side: as long you cannot drive, you will not drive, therefore no gas needed, which is basically worth like gold-dust nowadays.
05:49 AM randy: so if your car is the next month at the reparisshop, you virtually save many hundred of euros.
05:51 AM randy: </sarcasm>
05:52 AM XXCoder: techinically correct answer

06:10 AM JT-Cave: morning
06:22 AM alex_joni: morning
06:50 AM JT-Cave: snowing
06:50 AM JT-Cave: did you get emc1?
07:25 AM Loetmichel: randy: well, i rented a car for the time being. so your argument is invalid ;)
07:26 AM XXCoder: loet its actually valid if you ignore additional costs lol
07:26 AM XXCoder: thats why its techinically correct heh
07:28 AM Loetmichel: well, yeah. if you are ignoring th 288 eur a week for the rental PLUS the fuel
07:28 AM Loetmichel: ... and the fact that i STILL drive the renaul trafic despite ordering and paying for a VW polo... ;)
08:04 AM flyback is now known as carl_sagan
08:04 AM carl_sagan is now known as flyback
10:14 AM perry_j1987: so if i use a green wheel i can customize some carbide inserts?
11:36 AM -!- #linuxcnc mode set to +v by ChanServ
11:44 AM JT-Shop: I can't find anything in the docs that explain how to run a RIP :(
12:05 PM Tom_L: yeah i for the longest time wasn't even sure what that was
12:11 PM unterhaus: ./linuxcnc
12:14 PM perry_j1987: hows it goin
12:22 PM JT-Shop: unterhaus, . ./scrips/rip-environment
12:22 PM JT-Shop: then linuxcnc
12:23 PM roycroft: rip is an old dynamic routing protocol that has not been relative for 25+ years :)
12:23 PM perry_j1987: where is my hammer...
12:32 PM perry_j1987: fine i'll use the arbor press
12:43 PM Loetmichel: uuups... Wife got my help with getting a freshly baked bread out of the (steel) baking form... took me a good minute handling that beast... "thanks, you can go now." $me starts moving "OUCH!" $me turns around "well, its hot... even if i can touch the form with bare fingers..." ... If looks could kill i would be dead now.
01:00 PM perry_j1987: lol
01:05 PM CaptHindsight[m]: Loetmichel: the rental car bait and switch, you reserve the model they feature but when you get there it's some awful car that wasn't even on the list
01:07 PM Loetmichel: CaptHindsight[m]: nah. it was simply the only car on the lot
01:07 PM Loetmichel: ... and still is btw ;)
01:07 PM Loetmichel: its about twice as expensive as the class i booked. so i doubt he would let me have it if he HAD an alternative atm
01:10 PM CaptHindsight[m]: I rent at an agency a 15 min walk from me. Then I drive an hour to the airport to get a better model.
01:11 PM CaptHindsight[m]: Rental cars got so bad here during the lockdown that I was even given cars with expired license plates.
01:12 PM XXCoder: CaptHindsight[m]: what happens if police catch you with exired license plate if youre renting?
01:13 PM CaptHindsight[m]: XXCoder: whatever they feel like
01:14 PM roycroft: it depends on how much melanin you're carrying around with you
01:15 PM CaptHindsight[m]: I didn't notice for a few days. Didn't get stopped. They were also out of state plates.
01:22 PM XXCoder: in least it had plates :)
01:25 PM CaptHindsight[m]: I try to avoid having any issues with rental cars that might attract the local gestapo
01:26 PM CaptHindsight[m]: once had a brand new rental with temp plate sticker in rear window, was stopped within 24 hours for that
01:27 PM perry_j1987: hmm there is an unfortunate hole already drilled in this scrap alum im going to make the lathe plates out of
01:27 PM CaptHindsight[m]: "oh I didn't notice the sticker until after I pulled you over"
01:27 PM perry_j1987: time to get creative heh
01:38 PM perry_j1987: just about got this minilathe stripped down where it needs to be
01:38 PM perry_j1987: gotta get the saddle off now to bore the hole out bigger
02:00 PM CaptHindsight[m]: perry_j1987: which brand lathe?
02:00 PM perry_j1987: harbor freight
02:00 PM perry_j1987: its rapidly becoming only the bed and headstock lol
02:01 PM CaptHindsight[m]: pretty soft steel
02:02 PM CaptHindsight[m]: i was tempted to get one10+ years ago to modify
02:02 PM roycroft: i had one, but i sold it a couple years ago
02:02 PM perry_j1987: it was 47 bucks for two 500mm ballscrews with all the fixins
02:02 PM CaptHindsight[m]: but I end up with much better leftover parts from projects, so I use those instead
02:02 PM roycroft: it wasn't a bad machine, for what it was
02:03 PM perry_j1987: i went this route instead of replacing the VFD in the 9x20 heh
02:04 PM perry_j1987: i can lug this thing around myself without getting a friend to drive up an hour away
02:04 PM roycroft: but i got a 12x36 a few years ago, and that suits me much better
02:04 PM roycroft: although i sometimes think i'd like to downsize that one a bit
02:04 PM CaptHindsight[m]: cheap and easy project, good enough for brass and alu
02:04 PM roycroft: it consumes a lot of real estate for how often i use it
02:05 PM roycroft: a 10x24 would probably be the perfect size for me
02:13 PM perry_j1987: well ran into first stumbling block
02:14 PM perry_j1987: the stepper /bk10 mounts i made are not quite long enough for the couplers i have
02:14 PM perry_j1987: will have to make some standoffs to mount the stepper back a bit more
02:31 PM Tom_L: CaptHindsight[m], at least you haven't rented one that was involved in a crime yet
02:32 PM Tom_L: perry_j1987, nema23?
02:37 PM perry_j1987: ya
02:37 PM perry_j1987: 425oz for z
02:38 PM perry_j1987: cant remember off top of my head what x stepper was its up there too
02:38 PM perry_j1987: its nema24
02:49 PM CaptHindsight[m]: Tom_L: likely not other than "price gouging"
03:02 PM perry_j1987: there we go finished cutting my blanks out
03:03 PM perry_j1987: now to mount the spoilboard back up and sweep the grid lines in and get to cutting out the parts
03:04 PM perry_j1987: the POT switch on this mini lathe is on its way out
03:04 PM perry_j1987: the swich part doesnt click anymore
03:04 PM perry_j1987: when i get this all back together i should put multimeter on the leads of the pot
03:05 PM perry_j1987: maybe i'll get lucky and i could drive it with 0-10v from the breakout board!
03:20 PM unterhaus: phone spammer just sitting their making an obnoxious noise on the answering machine for reasons
03:23 PM roycroft: i'm getting a number of spam calls every day from "medicare specialists" or some such outfit
03:23 PM roycroft: they won't stop calling, no matter how much i ask them
03:23 PM roycroft: i've even tried shouting obsceneties at the callers
03:23 PM roycroft: that only seems to make them call more frequently
03:24 PM roycroft: and they call from a different number every time, so blocking their numbers doesn't help
03:24 PM XXCoder: I was getting so many calls on my cellphone number
03:24 PM XXCoder: wonder if thats the cause lol
03:24 PM XXCoder: not that I ever answer anyone
03:24 PM XXCoder: play a loud porn video and leave phone by it
03:25 PM roycroft: it's incredibly annoying
03:26 PM roycroft: i try not to be too harsh with the callers
03:26 PM roycroft: yes, they made the choice to work for a scammy company
03:27 PM roycroft: but they don't know that i'm getting multiple calls/day and that i ask them every time to stop calling
03:28 PM roycroft: speaking of which, i just got my third call of the day from them
03:28 PM XXCoder: honestly id not bother with insults or stuff
03:29 PM roycroft: i just hung up on them this time
03:30 PM roycroft: but i don't understand why they do it
03:30 PM XXCoder: money
03:30 PM roycroft: do they really think that if the call me incessantly, and piss me off, that i'm going to give them any money?
03:30 PM XXCoder: not company, workers. they work for money
03:30 PM XXCoder: companies can make crap decisions
03:30 PM roycroft: yeah, but why do the company they work for do this?
03:31 PM XXCoder: good question. expecially if they dont remove people who never will from list
03:31 PM roycroft: even if i would otherwise want their product/service, they way they behave on the phone guarantees i would never buy from them
03:32 PM XXCoder: yeah me either. I guess it works with enough people tha it works anyway?
03:33 PM roycroft: it almost makes me want to just cancel all my phone services
03:37 PM XXCoder: yeah lol
03:41 PM roycroft: i've been looking at computers on cl still
03:41 PM roycroft: looking for something that would make a decent cad workstation
03:41 PM roycroft: i ran across an ad for a "cad/graphics workstation" for $3200
03:41 PM roycroft: so i checked it out, just to see what it was - there's no way i'm going to spend that much on a used computer
03:42 PM XXCoder: its often better to build your own
03:42 PM roycroft: the guy was touting how everythign was top of line, and worth tons of money
03:42 PM XXCoder: you just need good gpu, decent pc, and massive amount of ram
03:42 PM roycroft: they he went and listed every single component, and what he paid for it
03:42 PM roycroft: i added it all up, and he spent $1900 building the machine
03:42 PM roycroft: and wants $3200 for it, now used
03:43 PM roycroft: what i'm looking for is a "gaming computer" in the $500 range
03:43 PM roycroft: most of those come with 8GB or 16GB of ram
03:43 PM roycroft: as long as i can upgrade to 32GB or 64GB that would be fine
03:43 PM XXCoder: my pc has 16 gb ram and pkenty for simpler cad stuff I do
03:43 PM XXCoder: you probably want 32
03:44 PM roycroft: the gaming gpus are not as good for cad, generally, as the cad gpus
03:44 PM roycroft: but older sw still works fine with gaming gpus
03:44 PM XXCoder: simple enough to get pc then upgrade it a bit
03:44 PM roycroft: yes, 32GB is the minimum i want
03:44 PM roycroft: that's what i'm thinking
03:45 PM roycroft: and if i get one for around $500, and find the gpu doesn't work as well as i'd like it's another $500 to get a middle of the road cad gpu
03:45 PM roycroft: but i suspect that a $500 pc with gaming gpu will still run solidworks better than a windows 10 vm on my imac
03:45 PM XXCoder: if you plan to get a cad gpu, as well as buy from ebay one of those gaming pcs where gpu was ri[pped out. tend to be cheap
03:46 PM roycroft: https://eugene.craigslist.org/sys/d/springfield-gaming-pc-gtx-1070/7433787054.html
03:46 PM XXCoder: gpu market is so bad that some people buy whole computers just for gpu then sell off pc
03:46 PM roycroft: that one actually doesn't look too bad
03:46 PM roycroft: a little more than i want to spend, but it's an i7, not i5, and it already has 32GB of ram
03:47 PM XXCoder: yeah. though make sure its not designed like laptop which is abd for latency if youre using it for linuxcnc too
03:47 PM roycroft: the fancy case with the internal lighting and clear side is irritating
03:47 PM roycroft: it would be dedicated to running solidworks and autocad
03:47 PM roycroft: never linuxcnc
03:47 PM roycroft: oh, it would probably also run whatever software i buy for my cnc router
03:47 PM roycroft: vcarve pro, most likely
03:48 PM roycroft: but that actually runs really well on my imac
03:48 PM roycroft: at least the trial version does, which claims to be indentical to the licensed version, except saving toolpaths is disabled
03:48 PM XXCoder: can always unplug led stuff.
03:50 PM roycroft: yeah, i can turn the lights off
03:51 PM roycroft: and spray paint the side :)
03:51 PM XXCoder: meh, clear means you can see when it needs cleanout
03:53 PM roycroft: i have a 2x/year cleaning schedule for my machines
03:53 PM roycroft: they're usually not too bad when it comes time to clean them
03:54 PM roycroft: athough the last couple years they were all pretty bad in the fall, after the smoke
03:58 PM XXCoder: I really need to cleanout mine lol
03:58 PM XXCoder: been over a year or 2
03:58 PM XXCoder: I only cleanout in summer. virtually only season I can bring out to release dust back to wild
04:03 PM roycroft: i have an anti-static electronics vacuum cleaner
04:04 PM XXCoder: yeah? any good one?
04:04 PM roycroft: yes, it's a decent one
04:04 PM roycroft: 3m
04:05 PM roycroft: https://www.amazon.com/dp/B00006HR5F
04:05 PM roycroft: it's the one the copier repair folks all have
04:06 PM XXCoder: nice. too bad its bit above my price range. saved it in wish though
04:07 PM roycroft: i've had mine for about 30 years
04:07 PM roycroft: it's very durable
04:19 PM JT-Shop: my air filter guy placed the order for 2 air filters again and this time paid for shipping
04:26 PM JT-Shop: LOL at this spam email I represent a high net-worth investor who is seeing investment opportunities away from his native country.
04:58 PM _unreal_: honey I'm home
05:14 PM Tom_L: JT-Shop, get any weather there yet?
05:51 PM JT-Shop: all sleet, about 2-3"
06:11 PM perry_j1987: well this just sucks
06:12 PM perry_j1987: zero off on work and then record it and then set next tool and tool setter and then jog it over till the tool tip is touching the work and axis reports the tool should be 7.8mm above the work still...
06:12 PM perry_j1987: gah
06:13 PM JT-Cave: you set all tools to fixture then set one to material
06:15 PM perry_j1987: https://wiki.printnc.info/en/controllers/linuxcnc/tool-setter-no-probe i have this implemented
06:16 PM JT-Cave: good luck
06:16 PM perry_j1987: its been working for 6 months now
06:16 PM perry_j1987: and today...
06:16 PM JT-Cave: how did you break it?
06:16 PM perry_j1987: i came out to the shop intending to get work done
06:16 PM perry_j1987: lol thats how i broke it
06:17 PM perry_j1987: is there a better way i should have implemented this tool length probe
06:18 PM JT-Cave: I'm guessing your doing tool changes and have to set the tool offset with each change
06:19 PM perry_j1987: er20 spindle ya
06:20 PM JT-Cave: simple is to just break up your G code by tool...
06:22 PM perry_j1987: then you have to do a whole lot of manual z touch offs
06:22 PM JT-Cave: takes a few seconds...
06:23 PM JT-Cave: are you using 50 tools or something like that?
06:23 PM JT-Cave: next easy way is to make a subroutine to touch off and forget about remap
06:24 PM JT-Cave: I use a subroutine for my plasma and touch off for each cut
06:28 PM perry_j1987: this printNC setup lets you touch off with a random tool and then you MDI M600 and then every subsequent tool call m6 will save an offset
06:30 PM Tom_L: the M600 is specific to them
06:31 PM Tom_L: JT-Cave, get revere all lined out?
06:32 PM JT-Cave: once you have a tool z to a fixture or setting device and that same tool z set to the material z then it's just a matter of resetting z to fixure
06:32 PM JT-Cave: working on them
06:32 PM JT-Cave: and Foxy
06:32 PM JT-Cave: I'm making all the stations for the assembly machine for revere as well as made the assembly machine frame
06:33 PM Tom_L: nice
06:33 PM JT-Cave: spent all morning fighting sleet and crap so didn't get station 1 done today
06:33 PM Tom_L: was that the line the mold they expedited for?
06:34 PM JT-Cave: yeah but now it's got an change order so a time break for us
06:34 PM Tom_L: snow is done here but still the bitter cold
06:35 PM Tom_L: single digits
06:35 PM JT-Cave: omg it's cold here too, single digits only one night so far
06:36 PM Tom_L: 4F by 7am
06:36 PM JT-Cave: ouch
06:36 PM Tom_L: at least the wind died down a bit
06:36 PM Tom_L: wind chill was a killer
06:36 PM JT-Cave: been windy here all day
06:37 PM JT-Cave: I need to take a photo of the bowls I'm making they are starting to look nice
06:37 PM Tom_L: yeah
06:37 PM Tom_L: i saw one early on
06:38 PM Tom_L: chicken bowls..
06:38 PM JT-Cave: lol aye
06:38 PM JT-Cave: and now I have to make some sibling bowls lol
06:38 PM Tom_L: new chuck works good ehh?
06:39 PM JT-Cave: oh yes love that chuck\
06:39 PM Tom_L: what do you finish them with?
06:39 PM Tom_L: oil?
06:39 PM JT-Cave: tried and true varnish oil
06:39 PM JT-Cave: very safe
06:39 PM Tom_L: that's what i wondered
06:41 PM JT-Cave: time to start the gumbo
06:41 PM Tom_L: waiting for a bowl pic :)
06:41 PM Tom_L: unless they're the same
06:55 PM roycroft: well i found a computer that i think will work for me
06:55 PM roycroft: a dell optiplex 9020
06:56 PM roycroft: it has an i7 4770 processor @3.40GHz, which should be fine for what i'm doing
06:56 PM roycroft: and it ws cheap - i got it at the goodwill, and since i just donated to them i had a 20% off coupon
06:57 PM Tom_L: roycroft, here's your new cad station: http://tom-itx.no-ip.biz:81/~webpage/cnc/cad-station.jpg
06:58 PM roycroft: i ended up paying $135 for it
06:58 PM roycroft: my neck hurts just thinking about having to scan all those displays
06:58 PM Tom_L: heh
06:59 PM Tom_L: 2-3 is bad enough
07:00 PM roycroft: my imac has 3 27" displays, and that's almost too much
07:00 PM roycroft: this machine i just got has an add-on graphics board
07:00 PM roycroft: not a great one, but it shoudl work ok
07:00 PM roycroft: radeon hd 8370
07:01 PM roycroft: that's not my current bottleneck, though, and i think i have identied my bottleneck
07:01 PM Tom_L: ssd was the single bigest improvement to mine
07:01 PM roycroft: sw is single-threaded, and it's really frequency bound
07:01 PM roycroft: and i just was reading about modern intel cpus and turbo mode
07:02 PM roycroft: they will only go into turbo mode if 1 or 2 cores is in use
07:02 PM roycroft: more than that and they run at normal clock speed
07:02 PM Tom_L: i swapped my i7 for an i5 because it was faster
07:02 PM roycroft: so my imac never goes in turbo mode
07:02 PM Tom_L: so i have a spare now
07:02 PM roycroft: but a stand-alone machine that's only running sw should use 2 cores at most - one for os-ey stuff, and one for sw
07:03 PM roycroft: the machine only has 8GB of ram, but it can be easily and cheaply upgraded
07:03 PM roycroft: i suspect that even with 8GB it will run sw faster than my imac
07:04 PM Tom_L: this one has 16 ddr4
07:04 PM roycroft: now to make room for another computer
07:04 PM roycroft: that's actually not too hard to do right now, as it will share the keyboard and one of the displays with my imac
07:04 PM Tom_L: i've only got 4 under the desk
07:04 PM roycroft: but i'll want a dedicated display for it eventually
07:04 PM roycroft: there are only two machines in my office right now - both imacs
07:04 PM roycroft: one is an older 20" one that's running linux mint
07:05 PM roycroft: hmm, that one might work out well in my shop
07:05 PM roycroft: and leave me room for a dedicated display/keyboard for this new machine
07:19 PM unterhaus: I have to check if the latency on my lcnc computer is related to the display, apprently if it has internal display set to auto you can get big delays
07:20 PM unterhaus: I usually just leave that alone, not really thinking about the potential issues
07:58 PM roycroft: amongst all the parcels that showed up today, the switch for my heat gun arrived
07:58 PM roycroft: i think i'll go finish repairing it now
07:58 PM roycroft: it will be nice having it working again
08:21 PM flyback: 20<flyback>30 https://dokumen.tips/download/link/usbhacking-1401555543
08:21 PM flyback: 20<flyback>30 https://documents.pub/download/controlling-usb-flash-drive-controllers-expose-of-hidden-features
08:23 PM XXCoder: flyback: whats up with those 2 links
08:30 PM flyback: hacking usb flash drives
08:44 PM _unreal_: well that was unexpected, a mosquito just flew into my hand as I closed it...
08:59 PM roycroft: that would be really unexpected here, as there are no mosquitos this time of year
09:00 PM roycroft: it will be late april/early may before i see any
09:16 PM _unreal_: anyone who lives in a seasonal area. gets them 10x worse in the summer
09:16 PM _unreal_: they are very mild here
09:19 PM roycroft: we just had our budget approval board meeting the other day for the country fair
09:19 PM roycroft: we've not had an event for two years, due to covid-19
09:20 PM roycroft: because of that, the mosquito control budget was increased by $10,000 this year
10:44 PM Bleepshop: `A mosquito flying by me here and now would be encased in an ice cube... 9.3F outside the shop door... LOL
