03:04 AM Deejay: moin
04:23 AM Tom_L: morning
04:31 AM lcnc-relay: <travis_farmer@> Morning
04:56 AM jfsimon: Hello are some people familiar with uCLinux ?
07:24 AM rdtsc-w: meister, if not a SPI timing issue, make sure there is adequate bypass capacitance on encoder board, and no ground bounce or ground noise
09:52 AM lcnc-relay: <travis_farmer@> gonna be going to a nice steakhouse for my Dad's birthday. gonna enjoy me a very good burger... 🙂
10:11 AM lcnc-relay: <skunkworks8841@> Hmm - my 1/4 beef is done.. Yum.
10:13 AM roycroft: hi folks
10:13 AM lcnc-relay: <skunkworks8841@> Survived another night!
10:14 AM roycroft: yeah, i'm doing ok
10:14 AM roycroft: and it was the second night in a row without any oxycodone
10:14 AM roycroft: i'm pretty sure i'm done with that stuff for good
10:17 AM -!- #linuxcnc mode set to +v by ChanServ
10:28 AM lcnc-relay: <skunkworks8841@> great!
10:28 AM roycroft: yeah, that's a major milestone
10:28 AM roycroft: my doctors still think i'm nuts for focusing on getting off it
10:28 AM roycroft: but i think it's the right thing to do
10:28 AM roycroft: and i still have some and still know how to use it if things go south
10:54 AM lcnc-relay: <roguish> roycroft: definitely get away from the opioids as soon as possible. they work good, but fuck you up in many ways.....
11:05 AM bjorkintosh: good job roycroft!
11:12 AM roycroft: yeah, i agree
11:13 AM roycroft: i'm kind of on the fence about ibuprofen, though
11:14 AM roycroft: it's really good for the bone healing, but it wreaks havoc on the digestive system, and stresses kidneys and the liver
11:14 AM roycroft: i'm having a hard time determining whether it is doing more harm than good, or vice versa
11:14 AM roycroft: i'm keeping the dosage low for now, while trying to get that sorted
11:15 AM bjorkintosh: there was a whole 'this american life' on acetaminophens. https://www.thisamericanlife.org/505/use-only-as-directed
11:16 AM roycroft: well i'm being directed to take lots of meds, so i'm not sure that "as directed" is the best advice for me
11:17 AM roycroft: the surgeon's office think i should probably be on opiods for a couple or three months, day and night
11:17 AM bjorkintosh: heh. certainly.
11:17 AM roycroft: they will be shocked when i inform them this week that i'm totally done with them
11:18 AM roycroft: i don't get the sense that they're "pushing" them as so may doctors have done who get kickbacks from the pharmaceutical companies - i get the sense that they are truly concerned about their patients' well-being
11:18 AM roycroft: i just think they've been indoctrinated in the "meds are good" mindset
11:22 AM Rab: I suspect patients typically complain about pain a lot, so doctors have a pre-emptive strategy to manage that.
11:22 AM roycroft: yes
11:22 AM roycroft: and while i do seem to have a fairly high tolerance for pain, i do have pain, and i don't like it
11:23 AM roycroft: but i think meds are best for making pain tolerable/manageable, not for eliminating it completely
11:23 AM roycroft: perhaps that's an unusual approach
11:24 AM roycroft: i was at the market a week or so ago, and one of the checkers was chatting with me about my surgery, as i was using one of those electric scooters at the time
11:24 AM roycroft: she was talking about her back surgery, and how she was getting morphine via an iv, and that was not making the pain go away
11:25 AM roycroft: she said she was on 100mg oxycodone and it took that much to put her in "her happy place"
11:25 AM roycroft: i was aghast
11:25 AM roycroft: 10mg was my high dosage, and 5mg is what i was trying to take whenever possible
11:25 AM roycroft: i can't imagine 100mg
11:25 AM roycroft: but i never took enough to get in a "happy place"
11:26 AM roycroft: i also do not know what her pain level was, of course, so i don't judge on that
11:26 AM roycroft: but going to a "happy place" to me seems like taking an excess of what is needed
11:28 AM pcw-home: I cant deal with opioids, they got me constipated for days, When I had kidney stones, toradol worked best (but it's a one time thing)
11:29 AM roycroft: yeah, i've had digestive and intestinal problems since i went to hospital
11:29 AM roycroft: i'm getting back to my normal constitution now that i'm mostly off the meds
11:30 AM pcw-home: Did you have any antibiotics? they can mess up your digestion for months...
11:30 AM roycroft: no
11:30 AM pcw-home: good
11:31 AM roycroft: they put a woundvac on my back after surgery, which sealed it up really well
11:31 AM roycroft: and as such i did not need antibiotics
11:31 AM roycroft: a woundvac takes the risk of infection down to effectively zero
11:32 AM pcw-home: Yeah I think they tend to avoid antibiotics a lot more now
11:32 AM roycroft: whenever possible
11:33 AM roycroft: not only can there be negative side effects, the body builds a tolerance to them, and they become less effetive over repeated use
11:33 AM roycroft: so they're used only when necessary now
11:53 AM Rab: For kidney stones I always had various flavors of hydrocodone, never pleasant. One stone took three weeks to pass and by the end of it I was mildly dependant. The constipation was, uh, a significant issue.
11:53 AM pcw-home: 3 Weeks? Oww!
11:55 AM Rab: Yeah, I was young, unemployed, and didn't have insurance. The next episode was many years later and I was in a better situation, so they used shockwave lithotripsy.
11:58 AM pcw-home: Yeah I remember those days. I broke a collarbone in a cycling fall without insurance, think it cost me about 25K (and the was ~30 years ago)
11:59 AM pcw-home: (landed on my shoulder so a compression fracture into about 4 pieces)
12:00 PM Rab: ouch
12:01 PM lcnc-relay: <die_limonade@> In germany when we fall down the stairs, we are always hoping that the crack comes from the broken leg and not from the phone. because you are insured, your phone isnt
12:02 PM lcnc-relay: <die_limonade@> +you hear
12:02 PM Rab: The last time I was unemployed, insurance was so expensive that it absolutely wasn't worth it unless I had some catastrophic bike/car accident. (Which was always a possibility, so I did pay for it.)
12:03 PM pcw-home: My wife was smart/decent enough to get coverage for our employees/ourselves ~25 years ago
12:03 PM pcw-home: Now we both have medicare (for how long , I don't know...)
12:05 PM roycroft: i'm on medicare now
12:05 PM roycroft: and i have type b coverage with co-insurance
12:05 PM roycroft: and yeah, for how long, i do not know
12:06 PM roycroft: i'm pretty sure medicare won't be axed before my current bills come in
12:06 PM pcw-home: Yeah we have an "advantage" plan
12:06 PM roycroft: that's what i have
12:06 PM roycroft: with part d, of course
12:18 PM * roycroft is currently wondering who the new pope will be
12:18 PM roycroft: i expect them to go back to a more "conservative" pope, i.e. a less jebus-like one
12:18 PM roycroft: but will they select another ratzinger?
12:20 PM roycroft: that selection could be a foreboding of our next election, should we have another one
12:26 PM xxcoder: dunno
12:27 PM lcnc-relay: <skunkworks8841@> the comment from the one of the news outlets is that Pope Franscis put a lot of the Cardinals? in place.. So maybe they will pick someone closer to the previous pope.
12:27 PM roycroft: they usually go back and forth between a "progressive" (jebus-like) and "conservative (not jebus-like)
12:28 PM roycroft: and francis was especially progressive
12:28 PM roycroft: benedict was especially conservative, though
12:29 PM bjorkintosh: goodness. Francis reigned for 12 years.
12:29 PM bjorkintosh: that's a good long time.
12:30 PM roycroft: for a job where the average age at the start of the job is upwards of 70, yes
12:30 PM xxcoder: yeah. quite lengthy for position usually ran by old person
12:31 PM bjorkintosh: John Paul was rather young then. 58.
12:31 PM bjorkintosh: reigned for 27 good years.
12:31 PM bjorkintosh: that should be a lesson I think. never too late to start something brand spanking new!
12:31 PM xxcoder: list shows it as 1978-1978?
12:31 PM roycroft: i don't know i it means anything, but the pope's last audience was with our vice president, just prior to easter mass
12:32 PM roycroft: john paul, yess - he died shortly after being installed
12:32 PM roycroft: john paul ii, his successor, is probably the one you're thinking of
12:32 PM xxcoder: ok
12:32 PM bjorkintosh: yes him.
12:32 PM bjorkintosh: from Poland.
12:33 PM bjorkintosh: his predecessor lasted less than 30 days.
12:33 PM roycroft: which is probably why such a young one was chosen next
12:33 PM roycroft: they did not want to have another redo any time soon
12:41 PM roycroft: i'm getting the stuff together so i can start testing my mini-router
12:44 PM rdtsc-w: good luck, be careful
12:44 PM roycroft: i have a 7i96, and i know that can handle the stepper motors just fine
12:44 PM roycroft: but the spindle that i have is a small dc spindle
12:44 PM roycroft: what do i need to control that?
12:45 PM * roycroft originally purchased the 7196 for a machine that would have a larger, 3 phase spindle with a vfd to control it
12:47 PM xxcoder: orginally it uses 0-10v from BOB
12:48 PM xxcoder: connected to that spindle control board
12:49 PM roycroft: right, and i want to eliminate that stuff
12:49 PM roycroft: i'm not going to use the bob at all
12:49 PM xxcoder: yeah. just saying what it was orginally so you can figure
12:49 PM roycroft: i don't mind using the spindle control board, if i can control it with the 7196
12:50 PM xxcoder: if that mesa can do volt range then it should be doable
12:50 PM xxcoder: im not sure if that spindle board have alternates to control signaling
12:52 PM lcnc-relay: <skunkworks8841@> mesa makes a 0-10v board.. Spinx? or something like that.
12:52 PM lcnc-relay: <skunkworks8841@> https://mesaus.com/product/spinx1a/
12:53 PM roycroft: i don't think the 7i96 can do that
12:53 PM roycroft: i have a mesa daughter board for spindle control - i forget what model it is
12:54 PM roycroft: spinx1a might work
12:54 PM roycroft: my immediate goal is 3 axis motion control
12:54 PM roycroft: the spindle can come after that
12:55 PM lcnc-relay: <skunkworks8841@> sure - I didn't know the 7i96 didn't have an analog spindle control
12:56 PM roycroft: a quick glance at the specs makes me think it's 0-5v, not 0-10v
12:56 PM roycroft: but do not take my word on that
12:57 PM Rab: roycroft, do you want speed control?
12:57 PM roycroft: i would prefer it, yes
12:58 PM Rab: And you have a DC motor driver with a control input?
12:58 PM xxcoder: I used 0-10v and seem to work, but could have been wrong dunno
01:04 PM lcnc-relay: <skunkworks8841@> what is 0to5v?
01:04 PM xxcoder: spindle control voltage. from zero to max rpm
01:05 PM xxcoder: though prically saying, spindle sucks at lower rpms. thats why I added magnets, for PID so it could increase voltage when rpm is lowered by cutting forces
01:05 PM roycroft: yes
01:08 PM xxcoder: theres control knob somewhere too in box
01:08 PM xxcoder: for spindle manual control
01:11 PM xxcoder: or maybe its at same place as spindle psu is at. which is still unknown lol
01:14 PM roycroft: i'll get it sorted
01:15 PM pcw-home: Yes, the 7I96S has spindle analog (5V to 18V FS) built in, the 7I96 does not
01:15 PM roycroft: first i need to get basic motion control
01:15 PM roycroft: aah, thanks pcw-home
01:16 PM pcw-home: SPINX1A is basically the same circuit in the 7I96S + FWD/REV outputs
01:16 PM roycroft: and since i'm borrowing this 7i96 from another project, which will use a vfd for the spindle, perhaps the thing to do is get started as i am planning on doing, and then order a 7i96s for this machine and return he 7i96 to the other project
01:16 PM pcw-home: The SPINX1A normally steals some 7I96 step/dir pins if added
01:16 PM roycroft: i don't anticipate needing forward/reverse switching
01:17 PM roycroft: money is tight right now, but i do have that wad o' cash from selling the buses
01:18 PM roycroft: that's all allocated for the shop remodel, but i may be able to borrow $150 from that
01:19 PM xxcoder: I guess the free way would be to just use BOB for spindle alone
01:19 PM roycroft: the rpi does not have a parallel port
01:19 PM xxcoder: ah yes thats true. too bad
01:19 PM roycroft: a paralell port hat for the rpi would cost about the same as the spinx1a
01:19 PM xxcoder: dont rpi itself have voltage output?
01:19 PM roycroft: 5v
01:20 PM xxcoder: wonder if theres a way to double it for 0-10
01:20 PM roycroft: a spinx1a + 7i96 would cost more than a 7i96s
01:21 PM roycroft: so i'm really thinking the thing to do is borrow my 7i96 to get the basic motion control going, then get a 7i96s when i want spindle control
01:21 PM roycroft: i'm assuming my hal file would be almost if not identical for basic motion contro with either board
01:22 PM roycroft: so testing with the 7i96 would not waste any time at all
01:22 PM xxcoder: yeah. it'll also provide understanding on how well machine moves ec
01:22 PM xxcoder: etc
01:25 PM roycroft: right
01:25 PM roycroft: i'm all about baby steps
01:25 PM roycroft: and before investing money in the machine i want to see how it moves
01:25 PM pcw-home: You can also use one of those common "5 AXIS Mach" BOBs to get 0 to 10V
01:26 PM xxcoder: its what he has
01:26 PM * roycroft thinks he has a plan not, but does not have a canal
01:26 PM xxcoder: but rpi has no serial part and bob well isnt exactly great
01:27 PM pcw-home: though they have gone up quite a bit in price (used to be about $6)
01:27 PM xxcoder: yeah and depending on where, tariff might hit for more too
01:28 PM roycroft: well jt has them in stock
01:28 PM roycroft: so as long as i order soon i should hopefully avoid having to pay a national sales tax
01:29 PM xxcoder: ya was talking about BOB pcw talked about, which is often from china :)
01:29 PM roycroft: oh, the bobs, youre talking about
01:29 PM roycroft: that would seem like going backwards to me
01:29 PM roycroft: a lateral move at best
01:29 PM roycroft: a mesa solution is a forward move
01:29 PM xxcoder: indeed
01:29 PM roycroft: at least that's how i see things
01:30 PM Rab: IIRC the 0-10V works by pulsing a parallel port pin to charge up a cap. Surely there
01:30 PM xxcoder: no parallel port on rpi rab
01:30 PM Rab: 's a way to PWM a RPi output to do the same thing.
01:30 PM xxcoder: it does have 5v but dunno if theres way to double volt
01:31 PM roycroft: well i'll mention again that i am borring this 7i96 from another project, and it will need to be replaced anyway
01:31 PM roycroft: replacing it with the 7i96s makes the most sense to me
01:31 PM Rab: Yeah, you'd have to do some analog trickery...might be hard to keep it reliable.
01:32 PM pcw-home: Yeah software PWM through RPI GPIO pin would work
01:34 PM pcw-home: What we do is use an optoisolator with push pull CMOS output (TLP2745) for isolation/level translate
02:00 PM lcnc-relay: <skunkworks8841@> you can just use the analog output on the bob.. Nothing else.
02:01 PM roycroft: but i'm not going to use the bob
02:01 PM roycroft: as i don't have a parallel port on the rpi
02:02 PM roycroft: it is lunch time
02:02 PM * roycroft thinks he'll go get the controller stuff down off the shelf in the studio so he can start working with the rpi and the 7i96
02:03 PM roycroft: i feel very much up to it, and i'll be using a sturdy step stool, and not a ladder
02:03 PM roycroft: the controller stuff is just mounted on a sheet of plywood, and not inside a metal enclosure, so it doesn't weigh that much
02:03 PM xxcoder: keep everything steady
02:06 PM pcw-home: The BOB can go on the 7I96 expansion connector (which is parport compatible)
02:09 PM roycroft: that went well
02:09 PM roycroft: i disconnected the 48v power supplies and removed them first, before taking the rest of it down
02:09 PM roycroft: now i have to disconnect the gecko drives, etc. that i won't need for this
02:10 PM roycroft: thanks, pcw-home - that might be a good way to test the whole machine before i buy the 7i97s
02:10 PM roycroft: 7i96s, rather
02:11 PM roycroft: i'm looking forward to bringing that machine back to life
02:11 PM xxcoder: me too :)
02:11 PM xxcoder: its been years since it last ran
02:11 PM roycroft: i'm looking at it kind of like my 3d printer
02:12 PM roycroft: a way to get my toes wet and get some experience before i build the bigger one from scratch
02:12 PM Tom_L: just don't get them too wet and slip and fall again
02:13 PM * roycroft is doing a good job of keeping them dry
02:14 PM roycroft: i'm also thinking about installing some anti-slip strips on my steps
02:14 PM roycroft: just in case
02:14 PM Tom_L: we don't want you to be worth more at the scrap yard than you are already
02:14 PM Tom_L: with all the pins etc
02:15 PM roycroft: i have had a year from hell regarding injuries and the like
02:15 PM xxcoder: roy plus it could probably make some of smaller parts for big router. and afterwards probably a lot of simpler engrave jobs
02:15 PM roycroft: one reason i'm really looking forward to closing the book on my old house is that when the move is done i can hopefully put that whole year behind me and start anew with a life of not hurting myself :)
02:15 PM roycroft: yeah, that's the plan, xxcoder
02:15 PM xxcoder: :)
02:15 PM xxcoder: good plan
02:16 PM roycroft: it's mainly for engraving, and it should be able to make small parts for the big router
02:16 PM roycroft: i'm still going back and forth on how to build the big one
02:16 PM Tom_L: gantry style?
02:16 PM Tom_L: that's what most do
02:16 PM Tom_L: i didn't
02:17 PM roycroft: as i get my shop organized i'm going to see if i can afford the space to move my current router table onto one my tablesaw tables
02:17 PM roycroft: yes, it will be gantry style
02:17 PM roycroft: the issue, as you may recall from when i was doing the design a couple years ago, is that i want to mount it on my current router table, so that it is out of the way when i need the router table
02:17 PM roycroft: and that presents a lot of design challenges
02:20 PM roycroft: https://roycroft.us/CNC-Router/
02:21 PM roycroft: that stuff is from about 3 years ago, and i've changed it quite a bit since then, but that still gives a basic idea of what i'm working on
02:21 PM roycroft: i basically need to keep the gantry rails below the surface of the router table
02:21 PM roycroft: which sacrifices quite a bit of rigidity, but it's the only way i can do it and still use the router table
02:22 PM xxcoder: indeed. thats great way to also protect movement system
02:22 PM roycroft: so i figure the gantry sides need to be pretty substantial to counteract the loss of rigidity
02:23 PM roycroft: i was also toying with having the dust boot move independently to the spindle
02:23 PM xxcoder: box style gantry top would make it very strong
02:23 PM roycroft: which is why the spindle has those big sides surrounding it
02:23 PM roycroft: an i may still want to do that
02:23 PM roycroft: but maybe not
02:23 PM xxcoder: thats always good idea. I saw one machine like that, and its amazing
02:23 PM roycroft: i haven't come up with a design for doing it that i like yte
02:23 PM roycroft: yet
02:24 PM xxcoder: shouldnt be complex. just rail and lever lock
02:24 PM roycroft: but i have a shaper origin now, and soon will have a mini-cnc router
02:24 PM roycroft: which gives me more time to design the bigger one
02:25 PM roycroft: i'm hoping to refine that design over the summer
02:25 PM xxcoder: I wonder if hollows inside gantry sides could be used to put in anti-vibration stuff
02:25 PM xxcoder: like those rubberlike things used in cars
02:25 PM roycroft: yeah, something like dyna-mat
02:25 PM roycroft: which works amazingly well
02:26 PM roycroft: ok, i have to run an errand before lunch is over
02:27 PM roycroft: i think i'll fire up the rpi after work or this evening, and see if it needs an os/linuxcnc upgrade
02:27 PM roycroft: then i can start work on the machine
02:27 PM xxcoder: cool
02:27 PM roycroft: do you recall the maximum spindle voltage, xxcoder?
02:27 PM xxcoder: sadly no. a second old url might have it in title
02:28 PM roycroft: i have 24v from the motion control power supply, and i have a bunch of 48v power supplies
02:29 PM roycroft: i have a variable-voltage bench power supply, but it's very low current - i might be able to use it for testing, but probably not for doing anything real
02:29 PM xxcoder: "500w air cooled milling motor ac 220v spindl..." is all I can read
02:29 PM xxcoder: its been long gone since order was in 2015
02:30 PM roycroft: this is a dc spindle, i believe
02:30 PM xxcoder: it is. typical chinesium posting
02:30 PM roycroft: i'll pull it after work and do some research
02:30 PM xxcoder: unless that was that nasty green router
02:30 PM xxcoder: ebay
02:31 PM roycroft: there is a part number on the spindle
02:31 PM xxcoder: oops wrong window, now searching ebay history
02:31 PM roycroft: i cannot read it while it's installed, but it is there
02:31 PM roycroft: it's probably generic, but i can also probably get some information on it by searching on that part number
02:32 PM * roycroft heads off to do the errands
02:32 PM roycroft: i'll catch up with you later, xxcoder
02:32 PM xxcoder: ok later
02:33 PM xxcoder: sadly ebay page is also gone "CNC 0.4KW Spindle Motor + Mach3 PWM Module +Mount+ PSU 480W+ 13pcs ER11 collet" title
02:36 PM Rab: The 400W spindles seem to be 48V: https://i.ebayimg.com/images/g/7kEAAOSwp1RZfrzl/s-l1600.jpg
02:37 PM xxcoder: sounds right, and spindle look exactly same
02:38 PM Rab: Interesting to see that there are BLDC spindles now: https://www.ebay.com/itm/263174105063
02:39 PM xxcoder: mores wires
02:39 PM xxcoder: does it do pid with spindle now or?
02:40 PM Rab: Twice the price, too. I guess it has better torque control?
03:12 PM Tom_L: my 1.2kw bldc spindle has good bottom end torque
03:12 PM Tom_L: that's why i got it over one of the high speed ones
03:12 PM xxcoder: brushless eh
03:13 PM Tom_L: 5500rpm max though which is fine by me
03:13 PM xxcoder: lot better torque too apparently
03:13 PM xxcoder: it depends on use really. wood you want higher rpm
03:13 PM Tom_L: no doubt
03:13 PM xxcoder: anyway bldc didnt exist at low price point in 2017 lol
03:14 PM xxcoder: we have so much resources now, or in least used to
03:14 PM xxcoder: no idea what will happen with tariffs
03:14 PM Tom_L: https://www.youtube.com/watch?v=trzO8H6tKW8
03:14 PM Tom_L: pretty hefty cut for that size mill
03:14 PM xxcoder: indeed
03:16 PM Tom_L: i did a few tests when i finished the mill for the spindle and cutters i'd gotten
03:17 PM Tom_L: find out where some limits were
03:17 PM xxcoder: that 400w one probably have lower limits, but still better than roys current mini router spindle
03:17 PM xxcoder: unless majority of job is wood, then current spindle is better
03:17 PM Tom_L: my sherline was 600w iirc
03:19 PM Tom_L: maybe ok for wood
03:21 PM xxcoder: strength is plenty but rpm dunno
03:23 PM xxcoder: I suppose can always just have lower ipm
03:30 PM roycroft: i got a big envelope in the mail from the hospital
03:30 PM roycroft: i thought it might be my bill, but it was just a survey
03:34 PM roycroft: there is a din-rail 24v dc power supply on my cnc controller board
03:34 PM roycroft: i do not remember why i got that - i'll have to see what, if anything, it feeds
03:34 PM roycroft: it's certainly not for the stepper motors - i have a 48v ps for them
03:36 PM lcnc-relay: <travis_farmer@> 24v logic power (limits, probes, ect...
03:37 PM roycroft: possibly
03:38 PM roycroft: and i could see using 24v for that vs. 12v or 5v
03:41 PM Tom_L: i had to use the 24v centertap on my supply to supply V for the 10 & 5v regulators since their input was a tiny bit less than 48v
03:57 PM roycroft: ok
03:57 PM roycroft: i need to get up every few minutes and walk around, and i've been walking out to the studio on those trips today and checking things on the router
03:58 PM roycroft: the 24v power supply is fed by a latching contactor that i turn on with a key on the main control box
03:58 PM roycroft: it is not feeding anything at the moment, so i'm assuming it's there for limit switches and the like
03:58 PM roycroft: as well, i was able to pull the spindle, and it says 48v
03:58 PM roycroft: so i can use one of my 48v power supplies for that
04:07 PM xxcoder: thats good. I felt it was 48v after seeing above listing, but wasnt 100% sure
04:37 PM roycroft: i have a half hour to go for work but i cannot sit for another minute
04:38 PM roycroft: i think i'll go out and work on the cnc router for a bit, and finish work later on
04:38 PM roycroft: i'll be standing when i'm out there, and that will be a lot better
05:16 PM * JT-MShop has to go to McLain Forest Products in Van Buren tomorrow and look at a feeder for the kiln furnace
05:16 PM JT-MShop: https://mcclainforestproducts.com/van-buren.htm
05:17 PM JT-MShop: I've been to the top of that huge silo a few times
05:17 PM JT-MShop: https://mcclainforestproducts.com/van-buren.htm
05:28 PM -!- #linuxcnc mode set to +v by ChanServ
05:28 PM roycroft: *chuckle*
05:29 PM roycroft: i just got a letter in the mail - it's an italian postage stamp i ordered on ebay, sent from italy
05:29 PM roycroft: the shipper smothered the envelope with stamps, as stamp collectors/dealers often do, but this collection on the envelope was a mix of old stamps in lira denominations and newer stamps in euro denominations
05:30 PM roycroft: someone at the italian post office took great care to put a cancellation stamp on all of the euro denomination stamps, and did not touch the lira ones
05:30 PM roycroft: the were mixed randomly on the envelop - not like lira on the left ane euro on the right
05:37 PM roycroft: i just logged into my medicare advantage web portal
05:37 PM roycroft: my total hospital/surgery bill, after adustsments, was $199,250.60
05:38 PM roycroft: my share of that is $1750, as I expected
05:38 PM roycroft: the original billing was $247,178.80
05:38 PM bjorkintosh: goodness.
05:38 PM xxcoder: its insane how high bills is in usa.
05:39 PM bjorkintosh: those numbers look made up!!
05:39 PM bjorkintosh: that's insaaaane.
05:39 PM xxcoder: essentally, it is.
05:39 PM bjorkintosh: they still could have picked up the whole bill. 1750 looks like a rounding error.
05:40 PM xxcoder: its a way to prevent people from just going to hospital anytime
05:41 PM roycroft: it's wrong
05:41 PM roycroft: it's actually $1900
05:41 PM roycroft: sorry - and that is what i expected
05:42 PM roycroft: my plan says that if i'm admitted to hospital my daily co-pay is $475 for the first four days, and everything that happens a the hospital is included
05:42 PM roycroft: i was there for four day, so i expected a $1900 co-pay
05:42 PM roycroft: it's the billed amount that's insane
05:42 PM roycroft: if i did not have insurace they would have billed me $250k
05:43 PM roycroft: but they billed my insurance $200k
05:43 PM roycroft: that's a $50k difference right there
05:44 PM roycroft: i did not log in to check that, but it was there waiting for me when i did
05:44 PM roycroft: and it's a big relief, because it looks like i'll be billed what i expected
05:47 PM bjorkintosh: glad it's not worse than that.
05:48 PM Tom_L: the doc can go buy a new putter now
05:48 PM xxcoder: yeah. I cant even afford that 1900 lol.
05:48 PM xxcoder: so if I fall, I'll just live though it.
05:55 PM roycroft: he can afford to get his masarati detailed now
05:57 PM xxcoder: depends on doc insurance
05:57 PM xxcoder: some doctors have very large insurance cost'
05:57 PM roycroft: a bunch of my claims while in hospital are under review still
05:57 PM roycroft: there's a chance some may be adjusted or denied, but i think that's a slim chance
05:57 PM roycroft: when the surgeon does his thing in hospital it's all billed through the hospital
05:58 PM roycroft: it's the office visits where i have co-pays
05:58 PM roycroft: and he bills my insurance directly for that
05:58 PM roycroft: i already have bills from him on my hospital bills
05:58 PM lcnc-relay: <ccatlett1984@> xxcoder is referring to medical malpractice insurance for the Dr. themselves
05:58 PM xxcoder: indeed
05:58 PM roycroft: oh, yeah, that
05:58 PM lcnc-relay: <ccatlett1984@> 😉
05:59 PM roycroft: i have no idea what this surgeon's malpractice insurance is
05:59 PM roycroft: i'm sure it is high
05:59 PM roycroft: and it's a pretty risky field - spinal surgery
05:59 PM roycroft: a tiny slip of the knife or too much pressure can cause paralysis
05:59 PM roycroft: but this guy is a rock star surgeon, and i don't think he's been sued successfully often
06:00 PM roycroft: that should help keep the insurance high, but not astronomical
06:00 PM JT-Shop: a friend's wife was an obstetrician and she had to carry malpractice insurance for 18 years after she retired
06:01 PM xxcoder: wow that long huh
06:02 PM roycroft: i guess you have to keep it until the statute of limitations runs out on everything you've done
06:02 PM roycroft: ok,, back out to the cnc project
06:03 PM roycroft: i needed to order some otc meds that are free with my insurance
06:03 PM roycroft: and i had a $41 balance left on their online store
06:03 PM roycroft: they had a back heating pad on sale for $39.99, so i got that too
06:03 PM roycroft: it might be nice - it's back-shaped, and has shoulder pads
06:04 PM JT-Shop: my wife needs one like that
06:04 PM roycroft: i've found that heat helps a lot - i tend to linger in the shower with the water turned up hot on my back after i'm finished with the cleansing part
06:05 PM roycroft: if you or she has a medicare advantage program, they usually come with some benefits like i have
06:05 PM roycroft: check and see if you can get one for free
06:05 PM JT-Shop: a normal heating pad just bunches up
06:06 PM Tom_L: does it velcro in the front?
06:06 PM Tom_L: target has one like that
06:06 PM Tom_L: covers the back and fastens in the front
06:07 PM roycroft: https://www.amazon.com/dp/B0DC68TGQ8
06:07 PM roycroft: it has a soft cushy tie for the front
06:07 PM Tom_L: they have one similar to that too
06:07 PM roycroft: i don't know how it will work out
06:07 PM JT-Shop: that looks much better than the std ones
06:07 PM roycroft: but i got it for ree
06:07 PM roycroft: free
06:07 PM JT-Shop: keep me posted
06:07 PM Tom_L: https://www.target.com/p/snailax-heating-pad-for-back-pain-relief-kh-019f3-2/-/A-1003206466#lnk=sametab
06:08 PM roycroft: i'm sure it will be worth what i paid for it :)
06:08 PM roycroft: i shall
06:08 PM roycroft: and my insurance ships via amazon, and i often get stuff the next day
06:08 PM roycroft: so hopefully i'll have it soon
06:09 PM xxcoder: scaling is funny. it looks cliff sized, but image shows it covering whole torso.
06:09 PM Tom_L: one thing i like about using the boys' trucks are the heated seats
06:09 PM roycroft: now i am off to the studio
06:09 PM roycroft: i hope i can find my hdmi to micro hdmi adapter so i can plug a display into the rpi
06:10 PM roycroft: oh, i have to adjust the ac temperature first
06:10 PM roycroft: that's why i came back to the office in the first place
06:10 PM JT-Shop: every vehicle we have has heated seats except the 82 C3 which has nothing
06:10 PM xxcoder: lol
06:10 PM xxcoder: you probably was hit with doorway mind wipe
06:11 PM Tom_L: my daily driver doesn't but the seat fits my back really well
06:11 PM xxcoder: only drove one with heated once. not too bad but meh
06:11 PM JT-Shop: the heater works in the C3 but the blower does not... and the AC does not work
06:11 PM Tom_L: you wanted a project car...
06:11 PM xxcoder: so you are saying your c3 have no chill?
06:11 PM JT-Shop: LOL
06:12 PM _unreal_: I have never owned a vehicle that has heated seats. though I have rented one or 2 before. was nice in the winter time
06:12 PM JT-Shop: no chill, no heat
06:12 PM _unreal_: though I shun WINTER regardless
06:12 PM JT-Shop: some day I'll fix the blower and the AC
06:12 PM _unreal_: current temp right now!!!! 77f
06:12 PM Tom_L: steering wheel is as well but i'm not nearly as excited about that
06:12 PM _unreal_: boca raton
06:13 PM xxcoder: my van was first one I had with functional ac, though it only worked for couple minutes. my focus is first fully functional ac one
06:13 PM JT-Shop: ridgeline, C8 and Goldwing have heated steering wheel/grips
06:13 PM _unreal_: my old ford ranger, and ford escort waggon both had decelerator buttons. most people called them AC I just called them the decelerator buttons
06:14 PM _unreal_: hehe
06:14 PM Tom_L: would they make it up a hill with the AC on?
06:14 PM _unreal_: ya 2-3 gear
06:15 PM _unreal_: both manuals
06:15 PM _unreal_: car was 4 speed, truck was 5. both maxxed out at 88mph
06:15 PM xxcoder: lol my first daily driver can, but only if I accelerate before hitting hill
06:15 PM xxcoder: my sis in law had borrowed it, and I warned her to do it, and she didnt so she got stuck creeping up hill very slowly
06:16 PM _unreal_: heh
06:16 PM _unreal_: >:)
06:16 PM xxcoder: it sure was great anti-thief measure, that is, if anyone wanted such a ugly car
06:18 PM _unreal_: this weeked was fun, I took my daughter to a few different places. 2 craft fairs, and got free entree to a Museum
06:18 PM xxcoder: I probably could have left door open with key in and nobody would take it.
06:19 PM _unreal_: ;brb quick shower
06:27 PM roycroft: great
06:27 PM roycroft: no power cord on the control panel
06:27 PM roycroft: and i can't find a schematic for it
06:28 PM roycroft: i'm thinking i was building it on the fly with the intent of generating a schematic after, but now i don't remember what all i did
06:28 PM roycroft: there are two latching relays, and a number of power distribution blocks
06:29 PM roycroft: it might take me a while to sort out what i did and figure out what i have to do now
06:31 PM roycroft: or find the wiring diagram that is in a different directory :)
06:32 PM JT-Shop: when I converted the Hardinge CHNC I made a lot of notes and wiring diagrams
06:33 PM xxcoder: yeah. its why I didnt disconnect much of anything before stowing away cnc router. so I could doc it later. ended up never doing that but yeah
06:35 PM roycroft: that wiring diagram is very much a work in progress, but it may have helped enough to get me going
06:36 PM roycroft: the data sheet for the latching contactors should fill in the rest
06:42 PM roycroft: well, back to the drawing board
06:42 PM roycroft: that panel is wired for 240v ac mains, which makes sense for the machine it was designed for and the location of the machine, but this little router needs to run on 120vac
06:43 PM roycroft: i'll have to start from scratch, and just borrow the rpi and 7i76 from the other controller
06:43 PM roycroft: for initial testing that should not be a big deal - i don't need all the safety features and fancy wiring
06:43 PM roycroft: but it's a bit of a setback, and i hope i have what i need readily available
06:44 PM roycroft: a lot of my electronics stuff is still packed away in boxes, but a lot of it is in its new home
07:20 PM _unreal_: blaaa doing laundry
07:27 PM roycroft: clean undies are always nice
07:28 PM roycroft: as are clean sheets
07:35 PM _unreal_: public laundry mat :( in the hotel
07:36 PM _unreal_: my sister is claiming she cant release the probate funds from are father now till 2026 for tax reasons btw.... shes about to get a legal notice, If I'm not given a REAL answer soon.
07:37 PM xxcoder: fancy meal for me today. chicken patties with swiss cheese, sourdough type buns, with olive oil in both sides
07:37 PM xxcoder: so full
07:38 PM xxcoder: I love using olive oil in place of butter. I dont like butter
07:38 PM roycroft: i use olive oil all the time
07:39 PM roycroft: and i especially like substituting it for butter when making things like grilled cheese
07:39 PM xxcoder: oh yes and little bit of sraracha sauce in
07:41 PM xxcoder: I dont think I ever tried olive oil grilled cheese sandwinch
07:41 PM xxcoder: but then I dont have a way to cook that
07:43 PM roycroft: you don't have a george foreman grill?
07:44 PM xxcoder: sadly no
07:44 PM xxcoder: maybe in future
07:44 PM roycroft: well be off to the goodwill with $15 in your pocket to spend
07:44 PM xxcoder: didnt think of that. will check out later
08:20 PM lcnc-relay: <big_kevin420@> my god what a trainwreck this chatgpt linuxcnc config a user on the forum is asking about
08:20 PM lcnc-relay: <big_kevin420@> https://forum.linuxcnc.org/media/kunena/attachments/39429/my-lathe.ini
08:21 PM lcnc-relay: <big_kevin420@> https://forum.linuxcnc.org/media/kunena/attachments/39429/custom.hal
08:27 PM roycroft: chatgpt linuxcnc config?
08:27 PM roycroft: a person would actually do something like that other than just to see what it does?
08:44 PM bjorkintosh: I'd use claude instead of chatgpt
08:45 PM bjorkintosh: it seems more reasonable.
08:45 PM xxcoder: I just wouldnt use ai to generate critical files.
08:51 PM lcnc-relay: <big_kevin420@> yeah, luckily it wouldnt run DEFAULT_VELOCITY = 5000
08:52 PM roycroft: i would use a proper liuxcnc tool and make sure i understand it before feeding it to a computer that's going to control a real machine
08:58 PM bjorkintosh: that too.
09:01 PM lcnc-relay: <big_kevin420@> yeah he was trying to do a remora one
10:58 PM roycroft: well the stuff i need for the controller project doesn't seem to be in the house
10:59 PM xxcoder: solar is dead. 3521% tariff
11:00 PM roycroft: there's a good chance that, if we ever have elections again, republicans may go the way of the whigs
11:00 PM roycroft: the libertarians might become the dominant far right wing party
