01:15 AM veegee: Fluke 87V has to be my all time favourite multimeter
01:21 AM XXCoder: yo
01:21 AM veegee: https://www.amazon.ca/Fluke-SV225-Voltage-Eliminator-Adapter/dp/B005H0NKDC
01:21 AM veegee: but look at that price
01:21 AM veegee: $5 in parts
01:21 AM unterhaus: do I have to install mesaflash on a lcnc system?
01:21 AM XXCoder: cheap lol dang thats lot of money
01:21 AM veegee: I know, if it were $40, I'd buy it
01:23 AM veegee: The auto hold feature doesn't respect its thresholds and I couldn't contact anyone at fluke who would listen
01:23 AM memfrob: unterhaus, mesaflash is for programming the mesa cards i think, not necessarily for lcnc functionally i don't think
01:23 AM veegee: auto hold on the other ones work fine
01:24 AM unterhaus: looks like it has to be installed from the lcnc github
01:24 AM veegee: But this one is great: https://www.amazon.ca/Extech-GX900-Graphical-Multimeter-Bluetooth/dp/B00OZ8TAJK#customerReviews
01:24 AM veegee: Ignore the 2 reviews by idiots who don't know how to operate a multimeter
01:25 AM XXCoder: both seem to be bt problems rather than usage
01:25 AM unterhaus: my fluke chose the moment I was trying to decide if I should hook my new psu to my new mesa card to have its battery die
01:25 AM veegee: I have this 6.5 digit bench multimeter and it's amazing: https://www.keysight.com/en/pdx-2891457-pn-34465A/digital-multimeter-6-digit-truevolt-dmm?nid=-32051.1242959&cc=CA&lc=eng
01:25 AM memfrob: veegee, what do they mean by "stray" ?
01:26 AM unterhaus: there's an intermediate state where you can't tell the battery is low from the display but it's not quite reading right
01:26 AM veegee: when measuring AC signals, like a power line, you can't tell if its live or not just because you see a voltage on your multimeter
01:26 AM veegee: it's because a neighbouring power line induces voltages in the line you're measuring
01:26 AM veegee: so it could be live and dangerous
01:27 AM veegee: 'or it could be completely safe but you're measuring a voltage still due to AC induction/transmisison line effects, etc.
01:27 AM veegee: only way to know is to drain that "ghost" voltage out, but simply connecting it to GND is silly
01:27 AM veegee: because if it were live, that'd be a dangerous short circuit
01:28 AM veegee: and multimeter inputs are always high impedance inputs so they don't drain any energy from the line (well _very very very_ little)
01:28 AM veegee: what that little adapter does is provide a low impedance path between the points you're measuring, allowing ghost voltages to drain out safely
01:29 AM memfrob: oh god what have i done..
01:29 AM veegee: But if the line is live, you'll get a proper, safe reading
01:29 AM veegee: your body acts like an antenna
01:29 AM veegee: put your multimeter in AC mode and measure the voltage between your mouth and GND
01:29 AM veegee: you'll see a big number
01:30 AM veegee: but obviously your body is not live, it's just a huge antenna
01:31 AM veegee: stray voltage eliminator gives you the reading you're looking for ("Is it powered or not and what's the real voltage?")
01:32 AM veegee: But back to the important point - Fluke makes great stuff, but sometimes they pull shit like this and it irritates me
01:32 AM veegee: I'll pay $600 for a high quality multimeter built to perfection. But no way in hell is little PTC thermistor/inductor adaptor that cost them lik $2 to make worth $100
01:32 AM CaptHindsight: it puts a load across the 2 connections to lower the impedance
01:33 AM veegee: ^ Yes that. I'm not good at explaining things :(
01:33 AM CaptHindsight: <bow>
01:35 AM veegee: I wanted to get the keysight 34470A over the 34465A just because the legendary LTZ1000 voltage reference
01:35 AM veegee: but it's double the price and I couldn't justify it just for an extra digit
01:36 AM veegee: Eventually the goal is to get this bad boy just for fun: https://www.keysight.com/en/pdx-2905513-pn-3458A/digital-multimeter-8-digit?cc=US&lc=eng
01:36 AM veegee: Well this one first: https://www.tek.com/oscilloscope/5-series-mso-mixed-signal-oscilloscope
01:37 AM veegee: A masterpiece in electronics lab equipment. But fuck me I can't afford $20,000 for that
01:37 AM veegee: But Siglent stuff is excellent value: https://siglentna.com/digital-oscilloscopes/sds2000xp/ so I'll start with that
01:38 AM sensille: and not even an OLED display
01:38 AM veegee: Just don't get their bench multimeters. I did a long term stability test on their bench multimeters against my LTZ1000 voltage reference and the keysight meter based on the LM399 stayed true
01:38 AM XXCoder: dont olloscope also serve as voltage and resistance measure?
01:38 AM veegee: the signlent one drifted and I returned it as faulty. If it were accurate, cannot beat it for the price
01:39 AM sensille: i have the siglent sds1102x-e. it's decent enough for me, but i'd go for 4 channels next time, maybe even with the LA addon
01:39 AM veegee: sensille yeah I have a 4 channel 200MHz siglent scope and I lvoe it
01:39 AM veegee: But I'd really like a mixed signal scope like the $20,000 tektronix one
01:40 AM veegee: This however is spot on best bang for the buck: https://siglentna.com/product/sds2204x-plus/
01:41 AM veegee: 4 channel 200MHz mixed signal, 2 gigasamples/s with a logic analyzer addon
01:41 AM veegee: also want to get a minimum 10kW DC electronic load, but I think I'll make that
01:41 AM Deejay: moin
01:42 AM CaptHindsight: when i was a kid we only dreamed of such things
01:42 AM veegee: But this is something I have to get: https://www.bkprecision.com/products/power-supplies/MR25080-250v-80a-5kw-programmable-dc-power-supply.html
01:43 AM veegee: DIY full bridge phase shifted ZVS dc/dc power supply is not easy to make
01:44 AM veegee: But I remain hopeful because this controller is available: https://www.analog.com/media/en/technical-documentation/data-sheets/1922f.pdf
01:44 AM veegee: And Linear Tech and Microchip are my all time favourite semiconductor companies. They deserve a gold medal for the quality of their datasheets and application notes.
01:45 AM CaptHindsight: how about TI's data sheets?
01:45 AM veegee: trash
01:45 AM CaptHindsight: heh, I hate them
01:46 AM veegee: LT's and Microchip's app notes are a work of art. You can learn so much about electronics just from reading them
01:46 AM CaptHindsight: I used to have to open 3 data books to use their parts
01:46 AM veegee: Like look at this: http://ww1.microchip.com/downloads/en/appnotes/01114a.pdf
01:46 AM veegee: it explains all that so nicely
01:46 AM CaptHindsight: one for the data sheet, one for the app notes and one for the package/mechanical/thermal
01:46 AM veegee: yeah I bought a kindle JUST for keeping their datasheets always on
01:47 AM veegee: made me sad that Analog Devices bought LT
01:47 AM CaptHindsight: I also need a 4K monitor 20 years ago when they didn't have them and I could read them without glasses
01:47 AM veegee: Yeah 4k or bust
01:48 AM veegee: anything less looks like shit
01:48 AM CaptHindsight: hasta banana
01:48 AM veegee: but 5k (LG ultrafine 5k, iMac 27") are even higher pixel density and perfect
01:48 AM veegee: best LCDs in existance
01:48 AM veegee: but OLEDs need to become a thing for monitors
01:49 AM veegee: shit I just remembered the acetylene cylinder is laying horizontally in my trailer since yesterday
01:49 AM veegee: I think I have to let it stand upright for a long time before I open the valve
01:52 AM Loetmichel: mornin'
01:52 AM Loetmichel: *hehe* i'm good! just drilled out a hardenend steel 3dprinter nozzle with a 0.4mm tungsten carbide drill. by "free" hand. without breaking the drill bit. THATs a first!
01:57 AM veegee: I'll machine you a medal
02:04 AM Loetmichel: to be honest: i was apprehensive. those 0.4mm TC drill bits break if you look at them wrong.
02:26 AM veegee: I'm going to buy a MidNite solar classic 200
02:27 AM veegee: Because there's no modern forklift battery charger that is: multi voltage, adjustable current, fully adjustable temperature compensation, fully adjustable voltages for the battery, switching DC/DC, etc.
02:27 AM veegee: For $1000 you get all that
02:28 AM veegee: For $1,000, best case you get a shitty old 120A fixed voltage ferroresonant charger
02:28 AM veegee: it'll weigh like 300 lbs and super loud
02:29 AM veegee: Instead, I just get the MPPT solar charge controller (which has custom user set fixed voltage mode for testing and fixed voltage sources) and a power supply and be fucking done with it
02:30 AM veegee: Supports any battery voltage, current limit, etc. Can parallel if I want to charge faster. What's not to like?
02:31 AM veegee: I can even use the old 48V ferroresonant shitbox as a temporary power supply until I make a more efficient high current power supply.
02:33 AM veegee: Hell I can feed the MidNite solar charge controller directly from a step down transformer and a 3-phase full bridge rectifier and a few capacitors to smoothe things out
05:41 AM JT-Cave: morning
05:53 AM Tom_L: morning
05:53 AM XXCoder1: morning
05:54 AM Tom_L: testing a new RTAI kernel... looks promising
05:58 AM XXCoder1 is now known as XXCoder
06:02 AM JT-Cave: are you testing it?
06:04 AM Tom_L: yeah trying to
06:05 AM Tom_L: gotta get linuxcnc to recognize it for the build
06:05 AM Tom_L: once i do, i'll try it on the mill pc probably
06:06 AM Tom_L: passed andy's crash test at least
06:08 AM Tom_L: https://github.com/NTULINUX/RTAI patches for linux-4.19.152 kernel
06:09 AM JT-Cave: cool
06:09 AM Tom_L: memfrob is looking for testers
06:13 AM JT-Cave: just cloned it
07:20 AM Tom_L: JT-Cave, read yesterday log for the test link etc
07:20 AM JT-Cave: here or devel?
07:21 AM Tom_L: here
07:22 AM Tom_L: start around 8:30
07:23 AM Tom_L: https://github.com/NTULINUX/RTAI/issues/13#issuecomment-640277640
07:23 AM Tom_L: you gotta add a path to that, or at least i did
07:24 AM Tom_L: https://github.com/NTULINUX/RTAI/issues/13#issuecomment-624265234
07:24 AM Tom_L: he's also interested in that abs test
07:25 AM Tom_L: the first test mine ran ~10k iterations before i called it
08:21 AM jymmmm: morning folks
08:44 AM Loetmichel: oh maaan, i'll never learn. Finally remembered to wear kevlar gloves when unloading sheet metal... (no more "paper" cuts)... half an hour later i drip boiling hot glue on my thumb nail. Its ALWAYS something :(
09:50 AM unterhaus: any tricks for fishing wire through a machine tool? There is flexible conduit that ends 5 inches inside the machine
09:50 AM unterhaus: wire has to turn 90 degrees to get out the hole
09:51 AM unterhaus: I can barely see what's going on with a snake camera
09:58 AM jymmmm: Loetmichel: AGAIN????
10:00 AM unterhaus: I got my 7i93 to respond to pings, so that's something
10:02 AM unterhaus: now I need to figure out how to use mesaflash
10:02 AM unterhaus: after I get my monitor at a reasonable height
10:11 AM FinboySlick: unterhaus: dental floss, cotton ball, vacuum cleaner?
10:14 AM unterhaus: I was thinking about that method
10:16 AM FinboySlick: unterhaus: Remember that the vacuum can go either end ;)
10:17 AM FinboySlick: I must say it would be rather amusing if you had to seal the entire machine just so you can pull a vaccum in the right place.
10:18 AM FinboySlick: 18 rolls of tape later...
10:33 AM unterhaus: it's the head of a lathe, not much area
10:34 AM unterhaus: monitor mounts cost a lot more than TV mounts
11:22 AM Tom_itx: JT-Cave, build going smooth?
11:23 AM Tom_itx is now known as Tom_L
12:02 PM JT-Cave: been running errands...
12:03 PM * JT-Cave got a huge chunck of bubinga and a smaller chunk of ebony
12:03 PM roycroft: nice, jt-cave
12:03 PM roycroft: use it thoughtfully
12:04 PM roycroft: both those species are becoming very scarce
12:05 PM roycroft: and most types of both are cites listed, so don't even think about exporting anything made with them unless you have proper documentation
12:06 PM JT-Cave: I only export Mesa cards :)
12:06 PM unterhaus: I wish I had docs for my pre-cites bubinga
12:07 PM JT-Cave: both pieces are at least 25 years old
12:08 PM unterhaus: did you pay retail? I saw that bubinga is outrageous right now
12:08 PM JT-Cave: my buddy gave them to me
12:08 PM roycroft: being in this country for 25 years and proving that they've been in the country for 25 years are two completely different things
12:08 PM roycroft: different by up to a $100,000 fine and some jail time
12:08 PM unterhaus: mine is at least 30 years old, too bad we couldn't see the future back then
12:09 PM JT-Cave: maybe I'll just make firewood out of them...
12:09 PM unterhaus: probably give you hives
12:09 PM * roycroft has some bits of ebony and rosewood that are cites-listed that he's been hanging on to for a long time
12:10 PM roycroft: whenever i start making my greene and greene style furniture and other things i'll start using small bits of that ebony
12:10 PM unterhaus: I don't think there is any practical effect on woodworkers using or even selling stuff that isn't cites documented
12:11 PM CaptHindsight: roycroft: about 20 years ago an exotic wood seller on the NW side of Chicago was selling large hunks of rare woods from a display from the world fair in the late 1800's
12:11 PM unterhaus: they used to use rosewood for lots of stuff
12:12 PM CaptHindsight: they were ~8 x 2 ft and 6 in. thick
12:12 PM CaptHindsight: were only $100's ea
12:13 PM CaptHindsight: they were found in the basement of the Field Museum
12:14 PM * JT-Shop ponders how thick to make this end grain cutting board???
12:14 PM roycroft: i'd make it at least an inch and a half thick
12:15 PM roycroft: cutting boards that are well-used need to be reflattened periodically
12:15 PM JT-Shop: I made the strips about 7/8" thick x 2" of red and white oak
12:16 PM roycroft: plus, the mass of a thick cutting board is nice
12:16 PM JT-Shop: I was thinking 1" finished thickness so it's not too heavy for my wife to use
12:16 PM roycroft: that's the drawback, especially if it's fairly large
12:16 PM roycroft: at 1" thick you can still resurface it a few times
12:16 PM JT-Shop: it's not that big right now it's 13" wide and how ever long
12:17 PM roycroft: well you could make it 1-1/2" thick and see how heavy it is
12:17 PM roycroft: if it feels too heavy you can plane it down
12:17 PM unterhaus: I want to make some drunken cutting boards
12:17 PM roycroft: hopefully your planer has inserts instead of just straight knives
12:17 PM JT-Shop: yea I have a 15" plane and a 22" drum sander
12:18 PM roycroft: i would not try to take off 1/2" of thickness with a drum sander
12:18 PM roycroft: not at my age
12:18 PM roycroft: and you're even older than me
12:18 PM JT-Shop: sadly it's straight knifes, the 8" jointer is inserts and leaves a perfect surface
12:18 PM roycroft: you might not get it done before you expire :)
12:19 PM JT-Shop: lol, I know what you mean especially a 1 3/4hp drum sander
12:19 PM roycroft: on a good day you can remove about 20 thousandths per pass
12:20 PM JT-Shop: right now all I have is 80 grit strip that came with it the rest should be here tomorrow
12:20 PM roycroft: for oak end grain i'd start with 30 or 50 grit
12:21 PM roycroft: and not go beyone 120 with the drum sander
12:21 PM JT-Shop: I could resaw it then smooth it up with the drum sander if I needed to take that much off
12:21 PM roycroft: i got some 180 for mine and it's pretty useless
12:21 PM roycroft: yeah, that would make more sense
12:21 PM JT-Shop: good to know, I have up to 120 on the way
12:21 PM roycroft: yes, after 120 i switch to hand-held sanders
12:22 PM roycroft: i mean, if you like burning the wood and glazing over the sanding belt in a single pass, get some 180
12:22 PM roycroft: or if you like taking 0.005" passes
12:23 PM * roycroft suspects he'll have the rest of the box of 180 sitting in the sander cabinet for the rest of his life
12:23 PM JT-Shop: I have 60, 80, 100, and 120 on order
12:24 PM roycroft: that's a good assortment
12:24 PM roycroft: and if you can start with the thicknesser, you can probably not bother getting 30 grit
12:25 PM unterhaus: should I buy a spare timing belt for my lathe? Seller offered a discount
12:25 PM roycroft: yes
12:26 PM JT-Shop: they do have 36 grit but I was wondering if it's useful or not
12:26 PM roycroft: now if i were to get a two-drum sander, i'd consider putting 120 and 180 on the drums
12:26 PM roycroft: for that end grain it might be
12:26 PM roycroft: because if you run the end grain through the thicknesser the knives will tear it up horribly
12:26 PM unterhaus: I want to make a wide belt sander for guitar tops
12:26 PM JT-Shop: that's what I thought
12:27 PM roycroft: i'd consider getting an insert head for it
12:27 PM roycroft: but for a 15" machine that would probably cost about $800
12:27 PM roycroft: imo it's worth it
12:27 PM JT-Shop: I wonder if they have one to fit my jet 15"
12:27 PM roycroft: almost certainly
12:27 PM roycroft: the ones at grizzly.com fit most machines
12:28 PM JT-Shop: I think I looked at shelix in the past
12:29 PM roycroft: https://www.grizzly.com/products/grizzly-15-helical-cutterhead-for-planers/t27695
12:29 PM roycroft: $595 for that one, if it works
12:31 PM roycroft: i think it's time to start rummaging through the wood pile
12:31 PM roycroft: hopefully i'll find enough scrapwood to make the shelves
12:34 PM JT-Shop: https://shelixheads.com/SHELIX_for_delta_15_inch_Planer_(22-780X5)
12:38 PM roycroft: i thought you said you have a jet
12:38 PM JT-Shop: yea, that's what I said... last table saw was a jet lol
12:39 PM roycroft: well it's a big chunk of change
12:39 PM roycroft: but i think you know what it will do for you, based on your experience with the jointer
12:39 PM JT-Shop: cheaper than a new planer :)
12:40 PM roycroft: and the first time you nick a piece of metal you'll be so thankful that you got the insert head
12:41 PM JT-Shop: I'm sold on insert heads after getting the powermatic jointer
12:41 PM roycroft: my jointer came with straight knives, but i upgraded it
12:41 PM roycroft: my thicknesser i bought with the helical head up front
12:42 PM unterhaus: I violated my rule about reading the manual before buying something complicated on ebay
12:42 PM roycroft: i would never want to go back to knives
12:42 PM JT-Shop: I bought the planer used but when I got the jointer new I went for the better head
12:43 PM roycroft: when i started building my workbench last summer the first thing i did was rotate all the inserts on both machines
12:43 PM roycroft: i'd been using them for a couple years or more without rotating them
12:43 PM roycroft: that took about 2 1/2 hours, but probably saved me more time than that in the end
12:44 PM roycroft: it wasn't a simple matter of rotating them - i removed each one, cleaned all the pitch off both the insert and the curter head, and then reinstalled it
12:44 PM roycroft: it really made a big difference in quality and efficiency though
12:54 PM _unreal_: I am so goddamn dumbfounded right now
12:55 PM _unreal_: in mach3 my in the diag. page I can SEE my limit switches are working
12:55 PM _unreal_: + and - pins
12:55 PM _unreal_: everything shows up as working
12:55 PM _unreal_: I press the limit the " on screen LED's" light up
12:55 PM _unreal_: everything lights up as expected
12:55 PM _unreal_: I hit home X will not trigger
12:56 PM _unreal_: I press the home side and the HOME led and the -limit led's light up. I press the other limit switch on x and the +x limit switch lights up
12:56 PM _unreal_: I do home cycle it plows right though the xhome limit like its not there
12:56 PM _unreal_: I dont get it
12:57 PM _unreal_: also I finished building my filter adapter for my inputs for the mach3 motion controller. WORKS like a charm now no more faulse sensing
12:57 PM _unreal_: now this WTF software issue
01:03 PM unterhaus: I think I might have thrown out all my ps2 cables, I need one to adapt my sacles to the dro
01:05 PM unterhaus: someone sells the adapters for $65 each
01:24 PM unterhaus: acu-rite letting me down on this one, no pinouts anywhere
01:24 PM unterhaus: I guess once I figure out which pins are 5v and ground I should be okay
01:42 PM _unreal_: unterhaus, hehe I use to purchase those universal DIY ps2 connectors from R/S all the time
01:42 PM _unreal_: infact I bet I have a few somewhere in a junk box
01:48 PM _unreal_: I just dont get it
01:48 PM _unreal_: I can not for the life of me figure out why I can see the limit switch work
01:48 PM _unreal_: its showing up in DIAG. but its like its not there
01:53 PM Tom_L: _unreal_, you have enough trouble for half the channel
01:53 PM _unreal_: heh
01:53 PM _unreal_: this one is just dumb founding me
01:54 PM _unreal_: how.. HOW can it be that it shows the limit as working but does not treat it as a limit in the software LOL
01:54 PM _unreal_: I dont get it
01:55 PM Tom_L: i don't do mach
01:56 PM rs[m]: veegee covers the other half
01:57 PM unterhaus: I have been throwing away ps2 cables, but some of them didn't make it to the dump yet
02:04 PM Tom_L: veegee is a menace to himself
02:22 PM * JT-Shop just ordered a Lux Cut III head for the planer
02:23 PM CaptHindsight: Tom_L: do you think you might have time to run the load/unload test again with RTAI?
02:24 PM CaptHindsight: andy ran the whole test suite 29 times and no crashes yesterday
02:25 PM CaptHindsight: not sure why he had issues the first time he tried, maybe used the older kernel by mistake or similar
02:45 PM perry_j1987: hows it going guys
03:00 PM JT-Shop: busy here trying to get all the water stations ready for tonights freeze
03:04 PM t4nk_freenode: lol rs[m] ;)
03:05 PM perry_j1987: sounds like fun
03:05 PM Tom_L: CaptHindsight, i can but i don't have that environment set up for the test i don't think
03:05 PM perry_j1987: im looking into options for tool setter probing with linuxcnc
03:08 PM Tom_L: CaptHindsight, i didn't keep track of how he initialized the environment for those
03:11 PM CaptHindsight: Tom_L: I think andy will be making packages soon so this will be easier
03:11 PM Tom_L: i've got the run tests, it just doesn't find them
03:12 PM Tom_L: since i put the RTAI back to like it was
03:14 PM CaptHindsight: perry_j1987: i think the QTPYVCP devs just got a new GUI for all that working
03:14 PM perry_j1987: i have er20 collet and getting mighty tired of doing it all manually lol
03:15 PM perry_j1987: so want to figure how to have it figure out the new tool length after each tool change
03:18 PM CaptHindsight: https://youtu.be/7zt_u_Ewz8Y?t=449 video of the installation
03:18 PM CaptHindsight: haven't used it myself
03:19 PM _unreal_: veegee, you live?
03:19 PM Tom_L: ok running the first crash test
03:19 PM Tom_L: or would you rather the abs one?
03:20 PM perry_j1987: that does look nice compared to axis
03:21 PM CaptHindsight: Tom_L: wasn't the load unload the one that brings the main issue to light?
03:21 PM Tom_L: i think so
03:21 PM Tom_L: the 2nd one isn't working here anyway
03:22 PM CaptHindsight: Tom_L: there might have been more than one problem though, have to ask Andy for the clearest info
03:22 PM Tom_L: i'll let the first one run a while
03:22 PM veegee: _unreal_ indeed it appears I do for yet another day
03:22 PM veegee: But for how long, nobody knows
03:22 PM _unreal_: heh
03:23 PM _unreal_: do you do mach?
03:23 PM _unreal_: or just lcnc?
03:23 PM veegee: I have used it before
03:23 PM _unreal_: :S
03:23 PM veegee: but mostly just linuxcnc
03:23 PM _unreal_: hum
03:23 PM _unreal_: I'm dumb founded right now
03:23 PM _unreal_: I can switch everything around all kinds of stuff BUT
03:23 PM t4nk_freenode: dumbfounded
03:23 PM CaptHindsight: perry_j1987: #hazzy IRC has been quiet since the linking between discord and IRC broke....
03:23 PM _unreal_: I can not get the x homeing switch to work
03:24 PM _unreal_: it lights up
03:24 PM CaptHindsight: perry_j1987: https://discord.gg/79Chbbty is the Discord qtpyvcp server
03:24 PM _unreal_: in the diag page as x- xhome
03:24 PM _unreal_: when I press the button
03:24 PM veegee: Never had that problem before
03:24 PM _unreal_: sees it as a button press
03:24 PM _unreal_: every limit switch " works " as intended
03:24 PM _unreal_: except the x home
03:24 PM _unreal_: x+ works
03:25 PM _unreal_: Y +/- z probe estop
03:25 PM t4nk_freenode: I heard there's an easy workaround for the limit switch problem....
03:25 PM veegee: I haven't used it in a few years though
03:25 PM _unreal_: ALL WORK
03:25 PM t4nk_freenode: press homing... then closely monitor until the machine reaches the end of the axis
03:25 PM _unreal_: but I can even switch port asignings to different switches and and x still does not work
03:25 PM t4nk_freenode: and press the button manually
03:26 PM _unreal_: t4nk_freenode, its not working at all
03:26 PM _unreal_: on the diag it reads as the button being pressed
03:26 PM _unreal_: but its not taking auction
03:26 PM _unreal_: if I hit any limit switch at any time it will "reset" the software
03:26 PM _unreal_: except for the x home
03:26 PM _unreal_: xhome its like I didnt touch
03:26 PM t4nk_freenode: auctions aren't really as profitable as they might appear though :(
03:27 PM _unreal_: I've been trying to out bid that damn switch for hours
03:27 PM t4nk_freenode: you are dumb
03:27 PM t4nk_freenode: euh,,, founded
03:28 PM t4nk_freenode: dunno man, feels like some logic problem somewhere
03:29 PM t4nk_freenode: fitted some leads the wrong way 'round somewhere I bet
03:29 PM _unreal_: its not hardware its softwre
03:29 PM _unreal_: the button works just fine
03:30 PM _unreal_: on the diag. page it shows a virtual LED display of all standard inputs/outputs
03:30 PM _unreal_: and when I press that limit switch it lights up
03:30 PM t4nk_freenode: doesn't matter, hardware, software.. they're mixed up.
03:30 PM _unreal_: so it see's it as a working signal
03:31 PM _unreal_: and defines it as x home
03:31 PM _unreal_: but it does not take action
03:31 PM _unreal_: I just dont get it
03:31 PM t4nk_freenode: I'm also willing to bet the solution involves reading on y our part
03:31 PM _unreal_: I could try RE-wiring to the high voltage limit switches and adding power :S
03:31 PM t4nk_freenode: comprehensive
03:31 PM _unreal_: I've been trying to find any info about it
03:32 PM _unreal_: every how to has said the same thing
03:32 PM t4nk_freenode: go over config files and see how they are set
03:32 PM _unreal_: that homing is the ONLY thing that is not working
03:32 PM _unreal_: x homming
03:34 PM t4nk_freenode: hehe, it's the OOONNNLYY thing you've Found not to be working, Yet, be positive :)))
03:37 PM MacGalempsy: anyone making chips?
03:38 PM _unreal_: chips?
03:39 PM t4nk_freenode: me, maybe, if my coffee settles :b
03:39 PM _unreal_: well I guess before I go do the stupid 3 hour drive I'll try wiring the x limit switches to the high power input port.
03:39 PM _unreal_: see if that wors
03:39 PM _unreal_: works
03:40 PM _unreal_: x is the last thing I need working so I at least have a basic working setup
03:40 PM MacGalempsy: yeah, cutting metal
03:40 PM MacGalempsy: sorry, no dip
03:40 PM _unreal_: hehe making chips was a big vague
03:41 PM t4nk_freenode: mmmm I don't think asking if ppl are 'making chips'... on a cnc channel...
03:41 PM t4nk_freenode: is hardly vague
03:41 PM t4nk_freenode: tbh
03:42 PM t4nk_freenode: (-hardly)
03:42 PM t4nk_freenode: ( or -don't)
03:46 PM _unreal_: considering we just had an american holiday YESTERDAY
03:46 PM Rab: Good time for making chips!
03:48 PM * Vq would love to have access to a silicon fab
03:48 PM * t4nk_freenode prefers real women
03:49 PM t4nk_freenode: yeah, I know... I oughtta be filing instead hehe
03:49 PM Vq: They can be even more expensive I believe...
03:52 PM Vq: http://sam.zeloof.xyz
03:56 PM Tom_L: CaptHindsight, 5000
04:06 PM Tom_L: CaptHindsight, it locked up around 7650
04:07 PM roycroft: i found enough scrap lumber to make my shelves
04:07 PM CaptHindsight: Tom_L: thanks
04:07 PM Tom_L: while i was editing a file :)
04:07 PM roycroft: the project is half done
04:07 PM CaptHindsight: Tom_L: just wait until builds debs
04:07 PM Tom_L: it ran thru 10k last night
04:07 PM roycroft: what's getting built?
04:07 PM Tom_L: stuff
04:07 PM CaptHindsight: it went over 100K here the other day
04:07 PM roycroft: a new version of linuxcnc?
04:08 PM Tom_L: an RTAI kernel
04:08 PM roycroft: oh
04:08 PM CaptHindsight: RTAI almost fixed
04:08 PM Tom_L: CaptHindsight, maybe this evening?
04:08 PM * roycroft installed preempt, which is fine for his hardware
04:08 PM CaptHindsight: wait for Andy
04:08 PM Tom_L: ok
04:08 PM roycroft: so i don't need to be intersted in this
04:08 PM CaptHindsight: roycroft: nah, go work on some woods
04:08 PM roycroft: which is good, because i'm intersted in too many things already
04:08 PM Tom_L: roycroft, naw, go run mach :)
04:08 PM CaptHindsight: ahhhh
04:09 PM roycroft: i'm just dashing off an email
04:09 PM CaptHindsight: mach
04:09 PM roycroft: i'll be back in the shop presently
04:13 PM unterhaus: Tom_L what's the mesaflash command to ask my 7i93 what firmware/pinout it has?
04:16 PM Tom_L: unterhaus, is it ethernet?
04:17 PM Tom_L: unterhaus_ is it ethernet?
04:17 PM Tom_dev: ./mesaflash --device 7i93 --addr --readhmid
04:17 PM unterhaus_: it's ethernet
04:18 PM Tom_L: there you go then
04:18 PM Tom_L: may not need the./
04:19 PM * JT-Shop has to drain the hoses for sure today
04:19 PM Tom_L: freeze warning ehh?
04:20 PM JT-Shop: be down to 19 by Monday night
04:39 PM JT-Shop: roycroft, ordered a Lux Cut III head for the planer
04:40 PM Tom_L: fancy
04:41 PM Tom_L: i bet the inserts to fill it cost as much as the cutter
04:41 PM JT-Shop: after using the powermatic jointer with insert head I was sold
04:41 PM Tom_L: replacements
04:41 PM JT-Shop: it comes with the inserts and some spares
04:42 PM Tom_L: did you price them?
04:42 PM JT-Shop: about $40 for 10 inserts with screws
04:42 PM Tom_L: how many does it hold?
04:42 PM Tom_L: 50-60?
04:42 PM JT-Shop: 68
04:43 PM Tom_L: they should last pretty good in wood i'd think
04:43 PM JT-Shop: yea, if you do much pine you need to clean pitch off of them from time to time
04:44 PM JT-Shop: they have 4 sides
04:44 PM Tom_L: yeah i saw that
04:44 PM Tom_L: nice thing about square inserts
04:46 PM JT-Shop: https://mywoodcutters.com/LuxCutIIIHead_for_DELTA_15_INCH_Planer_Model_22-785?search=22-785
04:47 PM Tom_L: do they give you extra screws for the inserts?
04:47 PM Tom_L: sometimes those are hard to find
05:17 PM JT-Cave: yea the inserts come with screws https://mywoodcutters.com/Lux_Cut_III_Heads_For_Planers_And_Jointers/Lux_Cut_III_Head_Accessories
06:20 PM Eric__: is there more than one buildbot repository ?
06:22 PM Tom_L: what do you mean?
06:23 PM Tom_L: http://buildbot.linuxcnc.org/
06:24 PM Tom_L: http://linuxcnc.org/iso/
06:24 PM Eric__: I think I have this http://buildbot.linuxcnc.org/ stretch 2.8-rtpreempt
06:25 PM Eric__: but when I apt-get install mesaflash it doesn't find it
06:25 PM Eric__: on the forum andy says it's in buster base
06:26 PM Tom_L: https://github.com/LinuxCNC/mesaflash
06:27 PM Tom_L: that's the official repo
06:28 PM Tom_L: it may be included in the iso and installed with linuxcnc, i'm not sure
06:29 PM Eric__: I was hoping not to build it since it's on the buildbot
06:29 PM Tom_L: it's real easy
06:30 PM Eric__: I need to make it so I can see my monitor before I would agree that it's easy
06:31 PM Tom_dev: git clone https://github.com/LinuxCNC/mesaflash
06:31 PM Tom_dev: sudo apt install libpci-dev
06:31 PM Tom_dev: make
06:31 PM Tom_dev: make install
06:37 PM flyback is now known as fishhead
06:37 PM fishhead is now known as i8086
06:38 PM i8086 is now known as flyback
06:40 PM Eric__: okey, I probably have to install git
07:04 PM t4nk_freenode: or just download the source from the git page
08:07 PM Eric__: that worked. Having to hold the keyboard while looking up at a monitor over my head is not ideal
08:09 PM Eric__: so it looks like the fw in it will drive a 7i33 on P2
08:10 PM Eric__: it has a batch of stepgens on p1, I can use that as io?
08:29 PM Eric__: I was liking pncconf until it won't let me go past the motor setup for some reason
08:32 PM Eric__: pncconf page on linuxcnc.org it totally out of date
08:39 PM Tom_L: Eric__, yes what you don't use can be GPIO
08:39 PM Eric__: yeah, pncconf told me that
08:40 PM Eric__: figured out you had to set encoder scales to get it to work
08:40 PM Eric__: so I can test it now
08:47 PM Eric__: I have to move a jumper so my 7i93 will power my daughter cards?
08:49 PM Tom_L: if you want it powered by the board probably so
08:49 PM Tom_L: you have the option to power it separately i think
08:50 PM Eric__: yeah, there are power connectors, but I'm pretty sure I don't have any
08:50 PM Tom_L: make sure you check if it has a 3.3 / 5v option
08:50 PM Eric__: maybe in my junk collection
08:50 PM Eric__: you mean the daughter card has that?
08:50 PM Tom_L: that would be for external 5v
08:50 PM Tom_L: yes
08:50 PM Tom_L: depends on the card. i don't have them all (yet)
08:51 PM Eric__: 7i33/7937 pretty common at one time
08:51 PM Tom_L: are those protection boards?
08:52 PM Eric__: 7i33 is servo interface, 7i37 is i/o
08:52 PM Tom_L: one of them sounded like an isolation board
08:52 PM Eric__: 7i33 at least requires 5v, so I guess I have to change that on the 7i93
08:53 PM Eric__: there is an isolated 7i37
08:53 PM Tom_L: yeah i just checked
08:53 PM Eric__: I think only parts of mine are isolated
08:53 PM Tom_L: 8output 16input
08:54 PM Tom_L: you also may have to supply field power to one of them
08:59 PM Eric__: not sure how the mosfets are driven on the 7i37, doesn't mention field power
09:00 PM Eric__: connectors only have obits and ibits
09:03 PM Tom_L: input output bits
09:05 PM Tom_L: you probably drive the + with the desired field voltage per output and use the - as the ouput or vise versa
09:05 PM Tom_L: i'm sure you could ask pcw_home
09:06 PM Eric__: the gates are driven through magic
09:06 PM Eric__: once I get my motors spinning, I will figure out the i/o
09:06 PM Tom_L: if you're using the ouput for inductive loads use a protection diode on them
09:07 PM Eric__: yeah
09:08 PM Tom_dev: ach ofthe 8 output switches is isolated from the others, allowing high side, low side, push-pulland other output switch configurations.
09:10 PM Eric__: not sure how much of it I'm going to use. I foresee using mostly inputs
09:12 PM Eric__: they allowed sunday hunting in PA, that's a bummer
09:13 PM Eric__: only 3 days though
09:13 PM Eric__: 2 have passed
09:13 PM Eric__: wondering why I heard gunfire on Sunday, someone must have tried to get a bear
09:17 PM t4nk_freenode: this is also the channel of the national hunting association btw
09:18 PM t4nk_freenode: chaired by _unreal_
09:18 PM _unreal_: ?
09:19 PM t4nk_freenode: come here, you little bear
09:19 PM t4nk_freenode: let me squeeze you
09:23 PM Eric__: I guess I won't be going mountain bike riding on sunday
09:24 PM t4nk_freenode: or at least leave your ear-muffs @home!
09:28 PM Eric__: partially don't want to get in their way
09:29 PM Eric__: some people aren't going to get the traditional monday off because they could go hunting on sunday
09:29 PM Eric__: Opening day Monday used to be essentially a PA state holiday
09:29 PM Eric__: like our trash gets picked up a day late
09:32 PM Tom_L: Eric__, i forgot what machine you're building
10:31 PM Eric__: bridgeport series II with servos retrofit
10:32 PM mrec: can anyone give me an MD5/SHA1/.. sum of the linuxcnc iso? (LinuxCNC 2.8.0 Debian 10 Buster PREEMPT-RT ISO)
10:32 PM mrec: 41b71c4956c0c89033a99a590ebaefec linuxcnc-2.8.0-buster.iso
10:33 PM mrec: hmm according to a chinese website that seems to be ok..
10:33 PM mrec: ok then my sd-card is probably dead
10:43 PM jesseg: Hmmm, my new 8" floppies just arrived. Where's the slot for these on my computer?
10:43 PM jesseg: :P
10:49 PM Eric__: I used to have an 8inch floppy drive with a cartridge full of floppies that would swap them automatically
10:50 PM Eric__: about the size of a mini-fridge
10:50 PM Eric__: scavenged it for parts almost immediately
10:59 PM mrec: copied again and again corrupted installation :-(
