01:55 AM Deejay: moin
02:42 AM Loetmichel: *ahhh* THE PAIN!... just tried to teach a coworker why you need a current limiting resistor for a led on a 9V battery and how to calculate it... went well until i divided 7V by 0.02A... "why is it 350? How can it be more than 7?" *head->desk* :(
03:04 AM sensille: easy. imagine you have 7 apples, and divide them between 0.02 people. so each get 350 apples
03:06 AM Loetmichel: sensille: i did it the other way around, i told him to imagine 7 apples sliced into 50 slices each and asked him how many people can have a taste with that
03:06 AM Loetmichel: paints a poor picture of certain african education systems though
05:09 AM Tom_L: morning
06:25 AM JT-Cave: morning
07:50 AM unterhausen: I bought a "smart podium" yesterday. It looks like it's just a touch screen, but it has a stylus
07:50 AM unterhausen: I thought it was worth an experiment for $25
07:51 AM unterhausen: it's really heavy for some reason
08:11 AM JT-Cave: I harvested some seeds from some cherry chocolate tomatoes and I tested one a few days ago and it's sprouted up nicely
08:30 AM Loetmichel: JT-Cave: is cherry tomato a genus or is it just "normal" tomatoes with a different upbringing?
08:30 AM Loetmichel: like bonsai=
08:30 AM Loetmichel: ?
08:32 AM unterhausen: that's probably the holy grail for tomato biologists though, plant that will not yield seeds that grow into a tomato plant
08:33 AM unterhausen: I expect a wild garden of tomato plants near the compost bins this year. The slugs had a field day with the late tomatoes, so a lot of them ended up being thrown in the general vicinity of the bin
08:34 AM unterhausen: last year, my sister had a volunteer tomato plant growing in her gutters. She lives in a city
08:35 AM unterhausen: I suppose a bird ate a tomato
08:41 AM perry_j1987: unterhausen advocados
08:42 AM perry_j1987: you plant a seed from an advocado and you wont get the same type of fruit off the tree you grow
08:46 AM unterhausen: must be a specific variety of avocado
08:47 AM perry_j1987: the advocados in stores are grafted
08:47 AM unterhausen: I know it's possible with some plants, but tomatoes don't seem to have that property
08:47 AM perry_j1987: they stil plant the seeds but they graft shoots onto the stalks and cut back all the natural growth
08:52 AM unterhausen: that seems typical of fruit trees
08:52 AM unterhausen: penn state salvage had a dremel 3d printer for $300
08:53 AM unterhausen: it had a note on it that it gets skew if printed over 220F
09:21 AM perry_j1987: always such a nice feeling when the air compressor shuts off
09:31 AM JT-Cave: I've kept tomato plants alive for 4 years by cutting the top off and soaking it in water for a couple of weeks until it grows roots
09:57 AM perry_j1987: nice
09:57 AM perry_j1987: i like growing them upside down in buckets
10:01 AM abanim20[m]: Hi, please can someone help me, Am having problem With my Proma150 THC on
10:01 AM abanim20[m]: QtPlasmaC. When it is cutting it work a while and sensors the float switch and trigger, and the torch will be going down.
10:11 AM unterhausen: That sounds like a noise problem, which can't be fixed with linuxcnc afaik
10:13 AM unterhausen: there is at least one thread on the forum talking about similar problems
10:14 AM unterhausen: do you have debounce in the hal setup?
10:17 AM JT-Shop: you asked the same question yesterday here... the forum is where the qtplasma guy hangs out
10:19 AM JT-Shop: I just use Axis on my plasma cutter... no need for all the complications of using plasmac
10:19 AM abanim20[m]: <unterhausen> "there is at least one thread..." <- No please
10:21 AM unterhausen: google may not give you the same results, but I see plenty on the forum with this search "linuxcnc.org thc noise problem debounce"
11:48 AM Rab: JT-Shop, I got the Epson LW-PX700 and it's great! A steal for the price. I wish there was a driver for Linux, but I have the software running in a VM with USB passthrough and that works fine.
11:49 AM Rab: It's a lot bigger than I expected.
11:52 AM roycroft: i've only ever tethered mine once
11:52 AM roycroft: the printer itself has all the features i need built-in
11:53 AM roycroft: which is good, because the mac os version of the software is very limited
11:53 AM roycroft: i've not tried the windows software
11:54 AM roycroft: at some point i'd like to download a couple symbols to the printer, but that's all i think i'll ever need to do with the computer interface
11:55 AM JT-Shop: Rab, I like mine a lot
11:56 AM roycroft: the only thing i don't like about mine is how it handles wrap-around labels
11:56 AM roycroft: and i kind of understand why they don't work well on that printer
11:57 AM roycroft: but i can still use my panduit label printer for those
11:57 AM roycroft: and as i've said, i have a lifetime supply of label cartridges for the panduit
11:59 AM Rab: The Epson ".leb" format is kind of interesting. It looks like a bitmap image--you can even view the label with standard software--but it seems to have a bunch of embedded metadata for the label editor.
12:00 PM roycroft: did you get the delux kit, rab?
12:00 PM Rab: If I had a print driver I could experiment with authoring labels under Linux, but the Windows driver didn't have a PPD or anything useful (for my skill level).
12:01 PM Rab: No, I just got the printer. The case etc didn't seem worth the price difference. I don't need the rechargeable battery.
12:02 PM roycroft: i ordered the basic one, but they sent the whole kit, and i did not complain
12:02 PM Rab: Yeah, it would be a nice bonus.
12:02 PM roycroft: i don't know that i'd have paid for the kit, but the rechargeable battery is really nice - i've printed a lot of labels and it is still going strong on the first charge
12:02 PM roycroft: the kit also comes with a couple rare earth magnets that attach to the back of the printer
12:03 PM roycroft: i tried them and they do hold it very securely on the side of a rack
12:03 PM roycroft: that's not my normal use case, in fact it's a pretty rare use case
12:03 PM roycroft: i'd not have paid for them, but i can confirm that they do work well
12:03 PM Rab: Hmm...don't let it swing past your wallet pocket, I guess.
12:04 PM roycroft: i keep most of my equipment like that in cases, so for me the case is worth paying extra for
12:04 PM roycroft: but if the machine is going to sit on a bench most of the time i can see that not being a useful feature
12:05 PM roycroft: i just sold some network equipment, and when i sell stuff like that i like to put some kind of labels on the gear to help identify it as coming from me, in case there's any question post-sale
12:05 PM Rab: Yeah, it's really only for a couple of pre-planned projects (and one's finished). But I'm looking forward to heatshrink labels for everything.
12:05 PM roycroft: i found that epson have some really nice black on matte silver labels, and they work brilliantly for that
12:06 PM roycroft: they look really professional - i print a label with a house-generated serial number, and slap a bar code on the label as well
12:06 PM roycroft: i haven't found any similar labels for my p-touch printers
12:06 PM roycroft: but yeah, i have shrink tubing in the printer 99% of the time
12:06 PM roycroft: that's why i bought it
12:07 PM roycroft: and i love the results
12:07 PM Rab: Any experience with adhesion? I got the vinyl, which they claim is stronger than the high-adhesion tapes, but it comes off pelican cases pretty easily.
12:07 PM roycroft: i used to print wrap-around labels for my cables, and then i'd put a piece of clear shrink tubing over them
12:07 PM roycroft: i haven't tried peeling any of them off
12:07 PM roycroft: i should probably try that some time soon
12:08 PM Rab: I've done that, but the heat gun turns the Brother labels black. It takes a deft touch.
12:08 PM roycroft: yes
12:08 PM roycroft: but that's not an issue any more
12:09 PM roycroft: the only place where i'll still use wrap-around cables will be applications where i don't have access to the cable end before it's terminated, or when labeling long underground cables in the vaults, hundreds of meters from the cable end
12:09 PM roycroft: in both of which cases i can't use clear shrink tubing over the label anyway
12:10 PM roycroft: i was just out, btw, on a fiber splice a couple weeks ago
12:10 PM roycroft: it was on a pull we did in 2008
12:10 PM roycroft: the fiber was in a vault, and had been covered with muddy water for 13 years
12:11 PM roycroft: we vacuumed the water out of the vault, pulled the fiber cables out, and could still read those labels from the panduit labeler that i applied all those years ago
12:11 PM Rab: Nice!
12:11 PM roycroft: so i guess those work well
12:11 PM Rab: What kind of splicer do you use?
12:12 PM roycroft: and i felt good, because the city engineer told me when i did the labeling that it was a waste of time, because they would be illegible in a year
12:12 PM roycroft: i do not do the splicing myself - i hire a splicer to do that work
12:12 PM Rab: ahh
12:12 PM roycroft: anyway, the city engineer was on-site for part of the splicing job
12:12 PM roycroft: and he was really surprised that we could still read the labels
12:13 PM Rab: 0wned
12:13 PM roycroft: i was very polite about it
12:13 PM roycroft: this guy has been dissing me ever since i started doing work for that city
12:13 PM roycroft: and i've proven my ability every time he questioned things
12:14 PM roycroft: but i've never rubbed it in his face
12:15 PM roycroft: the closest i've come is saying to him "you know how to design water and sewer lines. fiber optic cables do not work that way. i don't know how to design a water or sewer line, but i do know fiber optics"
12:17 PM roycroft: i thought that was fairly polite, but he did not take kindly to it
12:29 PM unterhausen: trying to help people online can be such a waste of time.
12:29 PM unterhausen: present company excepted, of course
12:30 PM roycroft: i've found that in government, the smaller the municipality, the more territorial folks are
12:31 PM roycroft: dilbertism is endemic to small town government
12:32 PM unterhausen: dilbert, alice, the pointy haired boss, or boss's secretary?
12:32 PM unterhausen: or Scott Adams himself, who was the model for the pointy haired boss by whoever actually draws the cartoons
12:33 PM roycroft: the dilbert model of measuring worth by the thickness of one's cubicle walls, and proximity of the cubicle to the phb's office
12:34 PM unterhausen: I missed that genre of dilbert cartoon
12:34 PM unterhausen: I thought the suckups always end up dead
12:34 PM roycroft: and, of course, the number of cubicles over which the phb reigns
12:35 PM unterhausen: phb is pretty obsequious around his superiors
12:35 PM roycroft: that's basic survival in that universe
12:36 PM unterhausen: I think it reached its peak with the etchasketch strip and has been downhill ever since
12:36 PM roycroft: i still read it on a fairly regular basis
12:36 PM unterhausen: Scott Adams' online personality ruined it for me
12:36 PM roycroft: it takes about 7 seconds out of my day, and there's occasionally something funny in it
12:37 PM roycroft: i do not know anything about scott adams as a person
12:37 PM roycroft: perhaps it's best i don't
12:37 PM unterhausen: yes, don't go looking, he's not good
12:37 PM roycroft: since i eschew all the popular social media, it's not hard to avoid that kind of stuff
12:37 PM unterhausen: it's amazing to me that someone so obviously confused can write dilbert cartoons
12:37 PM unterhausen: SA has a blog, best to avoid
12:38 PM roycroft: and were i to ever start engaging in social media, i think all it would do is confirm my notions about what a horrible cesspool it is
12:39 PM unterhausen: I recently joined a fb group called "small shops" and it's the worst of social media
12:39 PM roycroft: i have never once gone to facebook intentionally
12:39 PM unterhausen: I tried posting something workshop related and it was ignored, they like to fight about unrelated things
12:39 PM roycroft: the only times i've landed there are when a redirect took me there
12:40 PM roycroft: i should probably make sure that even that does not happen
12:40 PM unterhausen: it can be okay. But following the local papers is a mistake
12:40 PM roycroft: in /etc hosts: 127.0.0.1 facebook.com facebook
12:40 PM roycroft: that should take care of it :)
12:40 PM unterhausen: there is a branch of my family that's blocked
12:42 PM unterhausen: some orgs only use facebook for communication and it's okay for that
12:43 PM unterhausen: but blocking it is a good idea
12:43 PM roycroft: the concept of facebook is not inherently flawed
12:44 PM unterhausen: they tuned their algorithm in order to ruin it and now they can't reverse it
12:44 PM roycroft: but i knew from day one that facebook would manipulate its users to maximise profit, which they certainly have, and that the users would be oblivious to that manipulation, which they mostly are
12:45 PM unterhausen: the thing is it's ideologically aligned with zuck, and he's not going to allow a fix
12:45 PM unterhausen: if it tanks, then maybe
12:45 PM roycroft: i also knew that, like most new technology, users would not be able to handle it appropriately, and that it would take years for users to gain a perspective that allows them to utilized the technology positively
12:46 PM roycroft: i find facebook really amusing, in a not funny haha way, based on some recent events
12:46 PM unterhausen: at least the stonk tanked for the first time
12:46 PM roycroft: at the non-profit where i'm a board officer there was a very heated and truly horrible confrontation at the public board meeting three months ago
12:47 PM roycroft: a situation that has still not been resolved
12:47 PM roycroft: but as horrible as it was in the open board meeting, apparently the "discussion" on the non-official facebook pages related to the organization have been much worse
12:48 PM roycroft: in a private board session a month and a half or so ago, several board members suddenly became aware of the facebook algorithm that promotes disharmony (i'm being very polite here)
12:49 PM roycroft: and were horrified to discover that in spite of users' good intentions, facebook was deliberately dragging them down the dark path
12:50 PM roycroft: the organization has no official fb presense, and now these board members are calling for the organization to not only never have one, but to disallow staff and board from participating in any organization-related fb groups
12:50 PM unterhausen: yeah, it's bad for school boards and other local officials.
12:50 PM roycroft: it is
12:50 PM roycroft: it's sad, because it could be very useful for them
12:50 PM unterhausen: can't be combatted either
12:51 PM unterhausen: they really don't take reports of threats seriously at all
12:52 PM roycroft: all i can say is that i'm not feeling smug about knowing all along what fb would turn into
12:52 PM roycroft: i'm just happy that i had the foresight to avoid it
12:52 PM roycroft: i think it's beyond redemption at this point
12:53 PM roycroft: even if zuckerberg went away
01:10 PM CloudEvil: Change the algorithm, and you could likely fix it.
01:12 PM unterhausen: I have very little hope, but myspace seemed pretty popular at one point
01:12 PM unterhausen: oh well, going swimming
01:16 PM unterhausen: I did notice that it's much more difficult to see comments on fb now, which is a good first step. Default is "most relevant" which is never any comments
01:22 PM abanim20[m] is now known as Anim[m]
01:27 PM XXCoder: roycroft: all companies turn crap nowdays. why? 1: they need to make money. 2: they need to make MORE money each year
01:28 PM XXCoder: evenually companies mine internal resources, like grind down worker pay and cut benefits
01:33 PM roycroft: i've nothing at all against making money
01:33 PM XXCoder: me either
01:34 PM roycroft: i don't think it needs to be done via coersion and manipulation
01:34 PM roycroft: there are honest ways to make money
01:53 PM JT-Shop: XXCoder, those are not true... a company I'm automating some processes not for them to make more money it's so he can pay is employees higher wages!
01:54 PM JT-Shop: all the companies I've done work for try and produce the best products they can
01:55 PM XXCoder: industry tend to be, but not always, pretty good on that
01:55 PM XXCoder: im talking about services etc such as google, facebook, etc
02:06 PM roycroft: a lot of small companies are still honest and have integrity
02:06 PM JT-Shop: omg don't get me started on those two crap
02:06 PM roycroft: most larger ones, though, tend to move towards pure greed
02:25 PM JT-Shop: https://gnipsel.com/images/wood-working/bowls/bowls-09.jpg
02:30 PM roycroft: and now the miserable part begins
02:31 PM roycroft: i'm installing some new servers for the country fair office
02:31 PM roycroft: planning, procuring, prepping is all easy
02:31 PM roycroft: but the servers need hostnames
02:31 PM roycroft: i just totally punted on that
02:31 PM roycroft: i've been in too many prolonged, heated discussions about server hostnames with non-profits in the past
02:32 PM roycroft: at the freenet it once took us several months to get a badly needed, very expensive server online because the various committees, board of directors, and systems staff could not agree on a name
02:32 PM roycroft: i just emailed the executive director and told her i need two hostnames, and that i cannot install the server until i have them
02:33 PM roycroft: and that i am not going to get involved in any discussions about them
02:33 PM * roycroft wonders how long this will take
02:49 PM unterhausen: I once made the mistake of calling a computer "hammer" when the domain was "me.psu.edu"
02:49 PM CaptHindsight[m]: "Your password must be 8 characters"
02:49 PM enleth: XXCoder: what you are talking about are *publicly traded companies*
02:49 PM roycroft: this naming is going to be especially difficult, i think
02:50 PM unterhausen: poor little print server was owned so many times by the end of a week
02:50 PM CaptHindsight[m]: my password is Doc, Grumpy, Happy, Sleepy, Bashful, Sneezy, Dopey, and Snow White
02:50 PM enleth: with very few exceptions, all they care about is the next quarter
02:50 PM XXCoder: enleth: yeah thanks for more specific naming. hard time remembering stuff
02:50 PM roycroft: none of those names would be acceptable here, capthindsight
02:50 PM roycroft: they are all demeaning
02:51 PM roycroft: the diversity committee would scream bloody murder
02:51 PM CaptHindsight[m]: woosh
02:51 PM CaptHindsight[m]: oh well
02:51 PM roycroft: we can't name them after landmarks at the fair site, as they are mostly native names, and the cultural appropriations committee would scream bloody murder
02:52 PM roycroft: you can see why i'm staying out of this :)
02:52 PM roycroft: this is one of those organizations where if it's possible to take offense, offense is taken
02:54 PM XXCoder: id ise animal names if im forced to name bunch of servers, avoiding few of em
02:55 PM roycroft: there is a large sauna/shower facility on site - it's huge, wildly popular, and one of the few permanant structures there
02:55 PM roycroft: a few years ago someone offered to carve a totem pole for it, as it would fit in well with the facility, and the fair is located on ancient tribal grounds
02:56 PM roycroft: there was a prolonged discussion about it, and the local tribe who used to inhabit the land were consulted
02:56 PM roycroft: they consented to the carving of the totem, with the proviso that they be able to sign off on the design before it was executed
02:57 PM roycroft: they saw that it was being made to respect the tribe and their sacred grounds
02:57 PM roycroft: so the totem was carved
02:57 PM roycroft: mostly
02:57 PM roycroft: it was huge, and took hundreds of hours to make
02:57 PM roycroft: towards the end, a non-native fair member decided that it was offensive
02:57 PM roycroft: and consulted a different tribe who were completey unrelated to the site and its tribe
02:58 PM roycroft: the other tribe decided that it was offensive, and a cultural appropriation
02:58 PM roycroft: the bottom line: after another huge round of discussions, the totem was abandoned
03:05 PM Tom_L: just put a steel pole in the ground there with a merican flag at the top
03:10 PM roycroft: that would be right out at this organization
03:18 PM Tom_L: JT-Shop, now you need to put a ring of alternating walnut/ash etc wedges with your new jig in a new bowl design
03:19 PM Tom_L: start with 8 at the bottom and increase the wedge count as you stack them or something
03:22 PM Tom_L: https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcQDoESNKC8KMnLK00e0JMXzuQ0yrwKTO0EZWQ&usqp=CAU
03:23 PM perry_j1987: subaru doesnt have a half bad waiting room
03:23 PM Tom_L: they know you're gonna be there alot
03:24 PM Tom_L: sry... :)
03:24 PM perry_j1987: lol
03:24 PM Tom_L: zeshan sp? had a bad experience with their engines
03:24 PM Tom_L: thin ring lands that didn't hold up
03:24 PM perry_j1987: i just had a head gasket blow in one of the outbacks
03:25 PM perry_j1987: got the other one in right now for some maintenence
03:25 PM roycroft: just squirt some black rtv sealant on the head and slap it back together :)
03:26 PM Tom_L: damn JT-Shop you could make an entire business out of making bowls... http://www.accu-slice.com/store/p95/Segmented-Wood-Bowls.html
03:26 PM perry_j1987: im toying with the tought of that magic fluid fixer bottles for 26 bucks at the auto parts lol
03:26 PM CloudEvil: Or just vee it out, and then weld it back
03:27 PM Tom_L: the alum head is likely warped
03:27 PM Tom_L: or needed a retorque and never got it
03:27 PM roycroft: yes
03:28 PM roycroft: so set it up on your mill and take a pass with your biggest flycutter
03:28 PM roycroft: then slap the rtv black on it :)
03:28 PM perry_j1987: i just pulled into the house the other night and noticed a plum of white steam come out from under the hood and smelt the smell
03:28 PM Tom_L: that be water
03:28 PM alkabal: Hi all
03:29 PM alkabal: i appologize if my question is stupid but i need some clarification before continuing
03:29 PM perry_j1987: checked dipstick the next day and seen a bit of milky deposit on it
03:29 PM Tom_L: better that than oil
03:29 PM Tom_L: hope the antifreze didn't eat the bearings
03:29 PM roycroft: no questions are stupid
03:29 PM roycroft: asking if it's ok to ask a question is annoying, though
03:29 PM Tom_L: you ever see what that looks like?
03:29 PM roycroft: so just ask
03:29 PM alkabal: i try to enhance a little my Z axis config
03:29 PM perry_j1987: seen antifreeze eaten bearings?
03:29 PM Tom_L: yes
03:30 PM alkabal: i have measured a travel movepossible from table to more higher point (with limit switch) from 0 to 123
03:30 PM perry_j1987: nope
03:31 PM alkabal: my machine is homed as all 0
03:31 PM alkabal: after a M6T6 with know tool my machine display correctly for exemple 87mm chen the axis Z is at the higher position
03:32 PM alkabal: the tool offset in the table is -87mm
03:32 PM alkabal: it is logic for the moment ?
03:32 PM perry_j1987: roycroft you have sieg machine?
03:32 PM Tom_L: https://www.ms-motorservice.com/fileadmin/media/corporate_content/technipedia/Broschuere_Schaeden_an_Gleitlagern/8-korrosion/korrosion-1.jpg
03:33 PM Tom_L: alkabal, it measures from the top down
03:33 PM Tom_L: from where Z+ was set after homing
03:34 PM alkabal: after homing i'm on the more higher point displayed 0 on the dro
03:34 PM alkabal: without tool
03:35 PM alkabal: i like to have machine home position all 0
03:35 PM Tom_L: you typically want Z - to be down and home Z at it's highest point
03:35 PM alkabal: yes
03:35 PM alkabal: after homing
03:36 PM alkabal: but after loading a tool with autolength i want the dro display something like 87 at the higher point and 0 touching the table
03:36 PM Tom_L: the -87 in the tool table tells the machine it must be that much shorter to clear
03:37 PM alkabal: in my opinion this is normal
03:37 PM alkabal: because with tool mounted your axis Z is now more shorter
03:38 PM alkabal: i'm right ?
03:38 PM Tom_L: yes, by 87 units
03:38 PM alkabal: ot this is unusual config ?
03:38 PM alkabal: it is something regular ?
03:40 PM alkabal: one moment lool
03:40 PM alkabal: you says "yes, by 87 units"
03:40 PM alkabal: but it's wrong
03:41 PM Tom_L: maybe i don't get the problem
03:41 PM alkabal: axis is shorter from 123 - 87 = 36
03:41 PM alkabal: because i have 87mm from the tool to table
03:42 PM Tom_L: have you run it to see if it's wrong?
03:42 PM JT-Shop: http://linuxcnc.org/docs/2.8/html/user/user-concepts.html#sec:Machine-Configurations
03:42 PM alkabal: the problem is that i can do 36mm of chips from my table
03:42 PM alkabal: loll
03:42 PM Tom_L: don't put the tool in silly
03:43 PM Tom_L: just watch where it should be
03:43 PM alkabal: yes yes iof course that work like a charm except the possible 36mm chips
03:43 PM alkabal: looool
03:43 PM Tom_L: then you hit the kill switch
03:43 PM Tom_L: or just run
03:43 PM JT-Shop: lol
03:43 PM alkabal: yes but this is something really strange for me
03:43 PM alkabal: i try to setup something that prevent that
03:44 PM alkabal: sso before continuing to lost my time i have prefered to ask is all of what i have see is regular
03:44 PM alkabal: many thanks for confoirmation
03:45 PM alkabal: i can now says : i have a working setup that do not allow to do chips with table now
03:45 PM Tom_L: yet
03:45 PM roycroft: or coat your table with a layer of immutonium
03:46 PM perry_j1987: you guys by chance know what the voltage of the pot on these mini lathes is suppose to be sweeping
03:46 PM alkabal: loool
03:46 PM Tom_L: roycroft, it's unobtanium
03:46 PM roycroft: sadly, it is
03:46 PM alkabal: at the end the solution is really easy
03:46 PM roycroft: DAMN YOU, COVID SUPPLY SIDE SHORTAGES!
03:46 PM Tom_L: it gets blamed for sooo many things nowdays
03:47 PM roycroft: it's easy to blame it
03:47 PM Tom_L: it will fight back!
03:48 PM alkabal: for reference my solution is to swap axis ini config (using hal with a user defined mcode) on the fly after a tool changge
03:49 PM alkabal: simply using tool length as axis min
03:49 PM JT-Shop: hmm I'm going to have to be careful putting the segment base in the BP knee mill it only has 11.25" of travel
03:50 PM roycroft: this windows machine is performing just fine for me, but it takes a really long time for my cad software to load
03:50 PM roycroft: it runs fine once loaded
03:50 PM roycroft: i have a feeling that about a week before my 90 day warranty expires on the machine i'll be getting a 1TB ssd for it
03:51 PM Tom_L: JT-Shop, i had similar issues building the axis plates for my new mill on the sherline
03:52 PM perry_j1987: ah i just found a youtube vid that had the info on it
03:52 PM perry_j1987: it is sweeping 0-10v on the pot on this harborfreight mini lathe
03:53 PM perry_j1987: so i will be able to drive the spindle from linuxcnc
03:53 PM perry_j1987: easily
03:53 PM Tom_L: i missed that or i would have said 10v
03:53 PM Tom_L: actually pcw has a single channel analog board if you want one
03:54 PM Tom_L: same parts as mine has on the 7i47s i believe
03:54 PM perry_j1987: so today im going to throw one of my spare https://zoodmall.com/cdn-cgi/image/w=500,fit=contain,f=auto/http://luckyretail.com/Uploadfile/202011/202106041/500111596/500111596-6.jpg on the lathe
03:54 PM perry_j1987: replacing the old BOB that doesnt do speed control
03:55 PM perry_j1987: then it looks like i could also setup the relays to control the forward/reverse and on
03:55 PM Tom_L: probably
03:55 PM Tom_L: just don't flip the relay at 10k rpm
03:56 PM perry_j1987: heh
03:56 PM perry_j1987: i dont actually need rev
03:56 PM perry_j1987: i can manually leave it in forward
03:56 PM Tom_L: my sherline motor controller only had fwd
03:56 PM Tom_L: i set up a couple relays using delay functions in lcnc to have them switch at zero current
03:57 PM perry_j1987: im fine with leaving it set to forward and controling the on/off manually
03:58 PM perry_j1987: there is a master power switch on the lathe and then a switch on the pot
03:58 PM perry_j1987: so i'll need to wire up a relay to that switch lines to enable the spindle
03:59 PM perry_j1987: then setup another for mist/flood later on
04:16 PM perry_j1987: made some extended feet for the mini lathe today too
04:16 PM perry_j1987: now instead of feet 72mm apart they are 450mm apart lol
04:16 PM unterhausen: Perry, any recent pictures of the lathe?
04:17 PM perry_j1987: none
04:17 PM perry_j1987: im at subaru dealer atm waiting room
04:17 PM perry_j1987: i got ballscrews on both axis now though
04:17 PM perry_j1987: and just over 6 inches of travel on X :)
04:17 PM Tom_L: hope you're not waiting there while they change the head gasket
04:17 PM perry_j1987: no i got the other outback in now for a coolant change
04:18 PM perry_j1987: grabbed lunch and brought it here and let them have the car for a bit
04:19 PM perry_j1987: they quoted 2700 for a headgasket job though heh
04:28 PM perry_j1987: unterhausen https://i.ibb.co/qnhtyYg/66604280903-D1-F97256-12-F6-4372-97-D5-A9007-F9551-BF-HEIC.jpg
04:28 PM perry_j1987: here's the first cut i did earlier
04:29 PM perry_j1987: just with a grooving tool lol
05:41 PM perry_j1987: hows everyone doin
05:42 PM roycroft: marvelous, simply marvelous
05:43 PM perry_j1987: thats good
05:52 PM _unreal_: great my daughter has lice
06:41 PM solarwind: lol I am NOT buying gloves or other welding products with the brand name "Weld Porn"
06:41 PM solarwind: dumbest choice of branding ever
06:42 PM solarwind: If my little cousin or niece comes to the workshop and sees that, going to be awkward and I am not going to explain
06:45 PM CaptHindsight[m]: lame lame site
06:46 PM CaptHindsight[m]: no assless welding chaps or crotch-less aprons
06:46 PM perry_j1987: there we go
06:46 PM perry_j1987: got back out to the shop again
07:10 PM perry_j1987: https://zoodmall.com/cdn-cgi/image/w=500,fit=contain,f=auto/http://luckyretail.com/Uploadfile/202011/202106041/500111596/500111596-6.jpg what is the 5v port on top right
07:10 PM perry_j1987: common male and public port mean
07:15 PM CaptHindsight[m]: perry_j1987: in think it's connected to the 5V power on the USB connector with a jumper
07:16 PM CaptHindsight[m]: I usually power them with a USB cable since it's convenient
07:17 PM perry_j1987: whats the diff between the two though
07:18 PM CaptHindsight[m]: between which two?
07:19 PM CaptHindsight[m]: I don't think I have any schematics for a BOB with three relays
07:20 PM CaptHindsight[m]: Archivist used to have them all on his site
07:20 PM perry_j1987: one is labeled common and one is public
07:23 PM CaptHindsight[m]: helpful, isn't it?
07:23 PM perry_j1987: ya lol
07:23 PM CaptHindsight[m]: might mean Common 5V for the optos
07:23 PM perry_j1987: https://www.amazon.com/Stepper-Controller-Breakout-interface-Engraving/dp/B07BFTRTBC this has a bit more info
07:25 PM CaptHindsight[m]: yeah, I found the same info on ebay
07:27 PM perry_j1987: i've been using one of these for few years in the 6040 no issues
07:27 PM perry_j1987: got another for the lathe to swap out the old one that didnt have relays or speed control
07:27 PM perry_j1987: i actually aghve a spare cause amazon sent an extra duplicate order too haha
07:28 PM CaptHindsight[m]: do some poking around with a meter and some resistors across the outputs
07:29 PM CaptHindsight[m]: the USB 5V likely is the 5V public/common
07:29 PM CaptHindsight[m]: and USB Gnd is the common/public
07:32 PM CaptHindsight[m]: likely jumpers to connect or isolated the USB power from the 12-35V input power supply
07:32 PM CaptHindsight[m]: looks like it has an onboard regulator for 12V and 5V
07:35 PM CaptHindsight[m]: what you don't want is to connect the outputs from the onboard regulator 5V to the USB connector
07:36 PM CaptHindsight[m]: the PC end of the USB cable will not like that
07:39 PM perry_j1987: i got the 5v tied to the stepper drivers now
07:40 PM CaptHindsight[m]: https://www.electronics-lab.com/wp-content/uploads/2016/06/Parallel-Port-Breakout-CNC-SCH.png not the same board but you can see how they offer power connections to two sources and jumpers to prevent connecting them simultaneously
07:40 PM perry_j1987: the 5v down near the input section is going to the encoder and pulse sensor and limit switches
07:41 PM CaptHindsight[m]: a few things would be nice...
07:41 PM CaptHindsight[m]: a schematic
07:41 PM CaptHindsight[m]: a native English speaker to translate the connections and terminals
07:42 PM CaptHindsight[m]: some form of clear instructions for use by English readers
07:42 PM CaptHindsight[m]: but nnnaaaaaaaaaaahhhh
07:43 PM CaptHindsight[m]: perry_j1987: do your best to RE the board visually by the traces, multimeter and part number data sheets
07:45 PM perry_j1987: i dont understand why its so tough for them to hire native english translation services lol
07:48 PM perry_j1987: ok i just tested the pot and it is sweeping 0-11.93v
07:49 PM perry_j1987: so 0-12 hmm
07:50 PM perry_j1987: this board going to be able to drive the speed then?
07:50 PM perry_j1987: just not to max speed i guess?
07:50 PM perry_j1987: there is a trim pot on the 0-10 output i wonder if its able to bump up to 12
08:06 PM perry_j1987: thats odd
08:06 PM perry_j1987: the MDI commands history is universal
08:07 PM perry_j1987: its got all the commands in the history from my 6040 but im on axis for the lathe lol
08:12 PM perry_j1987: https://www.amazon.com/Breakout-Adapter-Controller-Engraving-MACH3V2-1-L/dp/B07KC7VLSL/ref=asc_df_B07KC7VLSL/?tag=hyprod-20&linkCode=df0&hvadid=475715987248&hvpos=&hvnetw=g&hvrand=12475866110257826742&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=1016367&hvtargid=pla-638091105013&psc=1 found better one
08:13 PM perry_j1987: this is like mine with the trim pot near 0-10
08:27 PM CaptHindsight[m]: perry_j1987: it's a Chinese thing about not getting a proper translation, I would be in the room there and they would NOT ask me to translate or proof read
08:28 PM CaptHindsight[m]: https://www.teachingnomad.com/blog/china/what-does-saving-face-mean/
08:28 PM CaptHindsight[m]: If they aren't corrected then they translated just fine :)
08:29 PM _unreal_: so just spent the past hour digging lice out of my daughters hair
08:29 PM _unreal_: fun times
08:30 PM _unreal_: was easy last time. easier... she was much shorter and less hair
08:30 PM _unreal_: SUCKS, YET AGAIN. I cant work on the @#%#$% machine
08:30 PM _unreal_: every night SOMETHING stops me
08:39 PM _unreal_: SOB.... just solved why my opto limit board was not working... fuck me
08:40 PM _unreal_: I dont know how or when?? but two of the POTS had to have been turned. the POTS must be 15 turn pots. I turned then ALLLLL THE WAY TO THE CC direction and the limit opto indicator lite started working. on the two that were not working.
08:41 PM _unreal_: so I spent like $30 buying replacement parts for the board. only to try one more time. with the original chip that I had JUST for the hell of it pulled out of the trash. NOTHING WRONG with it. it was a user error. HAD to have been.
08:42 PM CloudEvil: :/ Well, it's working I guess, so yay?
08:50 PM _unreal_: oyep....
08:50 PM _unreal_: yep
08:51 PM _unreal_: GOD every time a hair moves on my body from the ceiling fail. my skin crawls beause of my daughters .... condition
08:52 PM _unreal_: t4nk_freenode, any progress?
09:39 PM * Tom_L wonders why he would have an autodesk post processor manual
09:39 PM Tom_L: an old one
11:51 PM perry_j1987: this is sounding terrifying https://www.cnczone.com/forums/benchtop-machines/367038-posts.html lol
11:52 PM perry_j1987: 120v from legs of the speed control knobs to ground??!
