12:11 PM rdtsc: bjorkintosh I created an issue on xxdiff; we'll see what the dev says. https://github.com/blais/xxdiff/issues/35
12:43 PM bjorkintosh: excellent.
01:36 PM sinned69158 is now known as sinned6915
03:10 PM rdtsc: Weird error of the day: do a python3 send2trash.send2trash(file) without root on a root file --> gi.repository.GLib.GError: g-io-error-quark: Trashing on system internal mounts is not supported (15)
03:55 PM jfsimon1981_c is now known as jfsimon
04:59 PM JT-Shop: Tom_L, did you get touch to work
05:22 PM firephoto__ is now known as firephoto_
05:37 PM Tom_L: no
05:38 PM Tom_L: sorta
05:38 PM JT-Shop: maybe?
05:38 PM Tom_L: it's the darndest thing i've ever seen
05:39 PM Tom_L: it that one file that won't load just on touch
05:39 PM JT-Shop: very odd
05:39 PM Tom_L: it loads every where else
05:39 PM Tom_L: i woke up from a nap thinking it might be the limits and quadrant it was programmed for but doesn't seem to be the case
05:42 PM Tom_L: see what it does on your end
05:42 PM Tom_L: i posted it
05:42 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/
05:54 PM JT-Shop: rortuer test short?
05:55 PM Tom_L: was due to the tool table
05:56 PM Tom_L: it shows now but not in the same quadrant
05:56 PM Tom_L: it wanted T45
05:58 PM JT-Shop: it shows now but not in the same quadrant???
05:58 PM Tom_L: G54 offsets were off
05:58 PM JT-Shop: hmm
05:59 PM JT-Shop: are the g54 offsets set in the file?
05:59 PM Tom_L: i dunno, i'm working on that
06:02 PM Tom_L: it's ok now
06:02 PM Tom_L: it wasn't showing the program because the tool table didn't have T45
06:02 PM Tom_L: i copied my tool table over
06:02 PM Tom_L: naps are a very important part of life!
06:03 PM JT-Shop: emc didn't error out that the tool was not found?
06:03 PM Tom_L: i didn't try running it since i didn't see the plot
06:03 PM Tom_L: i'm sure it would have
06:03 PM Tom_L: once the setup was done it's fine
06:04 PM Tom_L: didn't think about that since mine are all set for 'me'
06:04 PM JT-Shop: odd that emc didn't load the plot because a tool was not in the tool table
06:04 PM Tom_L: no path to plot if the tool was missing
06:05 PM Tom_L: btw, what's the vertical slider on the home page for?
06:05 PM Tom_L: doesn't seem to do anything
06:05 PM JT-Shop: it does do something it tests the qss file LOL it's gone now
06:06 PM Tom_L: ok
06:06 PM Tom_L: it's working fine now
06:06 PM JT-Shop: great... how far are we from 1.0.0?
06:06 PM Tom_L: fix the html
06:06 PM Tom_L: or upload it....
06:07 PM JT-Shop: which html?
06:07 PM Tom_L: i pushed a 1 line edit to my readme
06:07 PM Tom_L: html...
06:08 PM JT-Shop: I'll go and pull that in a few
06:08 PM Tom_L: Some items in the plot can be turned on or off and note the program limits default to metric for now.
06:08 PM Tom_L: inch
06:08 PM Tom_L: you did fix the typo
06:08 PM JT-Shop: they should default to inch
06:08 PM Tom_L: they do
06:09 PM Tom_L: that's not what the doc says
06:09 PM JT-Shop: https://github.com/jethornton/flexgui/blob/master/flexgui/src/libflexgui/flexplot.py#L168
06:09 PM Tom_L: right
06:09 PM Tom_L: i knew you'd switched it
06:10 PM rdtsc: ya guys are prolly gonna shoot me... but how hard would it be to have an imperial/metric toggle?
06:10 PM JT-Shop: ah I see the limits default to metric for now.
06:11 PM JT-Shop: for the plotter?
06:11 PM Tom_L: rdtsc, there is one
06:11 PM Tom_L: and if your gcode is metric so be it
06:12 PM JT-Shop: rdtsc, are you talking about the DRO labels or the DRO in the plotter?
06:13 PM Tom_L: you don't have an 'overlay' button on touch but the rest work it seems
06:13 PM JT-Shop: hmm, I thought I had them all in touch...
06:13 PM Tom_L: 12 in all
06:13 PM JT-Shop: yup missing one then
06:14 PM Tom_L: i added one to test but removed it
06:14 PM rdtsc: if ya take a look at the Langmuir Cut Control UI, there's an imperial/metric toggle in the upper right corner. thought that might be a nice feature for Flex (but admittedly have not experimented with it yet.) https://www.langmuirsystems.com/cutcontrol/guide
06:14 PM JT-Shop: what does it toggle?
06:15 PM rdtsc: whole UI from metric to imperial it looks like
06:16 PM Tom_L: wouldn't that be done in the ini with units?
06:19 PM Tom_L: haha
06:19 PM rdtsc: perhaps it would have to be
06:20 PM Tom_L: i set units to mm and checked the metric checkbox in the plot and the plot shows 101.6 mm but the G54 offset is inch
06:20 PM Tom_L: no, there is more to it than just 'units'
06:20 PM JT-Shop: hmmm
06:21 PM rdtsc: well that and the gcode parser it going to "read" the code depending on the .ini setting
06:21 PM Tom_L: i think that would introduce a bag o worms
06:22 PM rdtsc: big 'ol bag
06:22 PM Tom_L: for one thing if you had set any fixture offsets in inch, the numbers stay in the .var file however changing 'units' makes them read back as mm not inch
06:22 PM Tom_L: i just checked that
06:23 PM rdtsc: looking like a "set-it-and-forget-it" thing
06:23 PM Tom_L: any precision that was set to any input or display value would be off as well
06:23 PM Tom_L: if i want .0000 precision in inch, that wouldn't translate in mm
06:24 PM Tom_L: it's set in the ui file
06:24 PM Tom_L: any display that showed " on 'in' would be wrong for mm
06:24 PM Tom_L: i'm not sure any do
06:25 PM rdtsc: might be worth mentioning in the docs to set the .ini to match the machine properties before doing any .ui construction
06:25 PM rdtsc: (and not change it)
06:25 PM Tom_L: freecad fought that for a while
06:26 PM Tom_L: i dunno if they ever resolved it completely
06:26 PM rdtsc: topological naming problem? :)
06:26 PM Tom_L: it was set up using the metric system
06:27 PM rdtsc: Having two systems is bonkers anyways
06:27 PM Tom_L: yeah, everything should be imperial :)
06:27 PM rdtsc: freedom units! :)
06:29 PM rdtsc: ok so nevermind JT; a note for the designer to keep the .ui in the coordinate system matching the .ini file might save a headache down the line.
06:29 PM JT-Shop: ok, thanks for hashing that out
06:32 PM rdtsc: Oh, one thing I wanted to try, unsure if this is possible, was to place an extra set of DROs for X and Y: +/-(tool radius). So we can see where the edges of the tool are. Ex: if a 1" tool is installed and X is at 1.5", we can see that one edge of the tool is at X=1.0 and the other side at X=2.0.
06:34 PM rdtsc: Easy math for 1" tools but not so easy with a 7mm tool...
06:35 PM JT-Shop: it "could" be possible to show the XY of the outside of the tool...
06:36 PM rdtsc: mainly for manual milling operations
06:36 PM rdtsc: or milling-to-create-gcode operations
06:41 PM * JT-Shop calls it a day
06:41 PM bjorkintosh: https://www.youtube.com/watch?v=CFA7iAnYZMs
06:41 PM bjorkintosh: Goodnight Gracie.
06:43 PM Tom_L: JT-Shop, so how close _are_ we?
06:43 PM JT-Shop: I think we are really close
06:43 PM * rdtsc is looking for any new .debs
06:43 PM Tom_L: i didn't see much else in the docs i couldn't live with :)
06:44 PM JT-Shop: that monitor/keyboard with a rpi hanging off is nuts
06:44 PM Tom_L: huh?
06:44 PM Tom_L: oh i didn't click
06:44 PM JT-Shop: what bjorkintosh linked
06:44 PM Tom_L: i see now
06:45 PM bjorkintosh: well it permits access to the pins. I'm sure they'll come up with a better design in time.
06:45 PM JT-Shop: fix the docs in the am
06:45 PM Tom_L: we'll see what else i can find overnite
06:46 PM Tom_L: you got rid of the vertical slider you said
06:47 PM Tom_L: was putting a bunk bed together for the niece so i'm in 'niece' mode
07:18 PM lcnc-relay: <skunkworks8841> https://jauriarts.org/_matrix/media/v3/download/jauriarts.org/tBxYnlwkafmPDxAVXWTPEPId/PXL_20240810_210702300.jpg
07:18 PM lcnc-relay: <skunkworks8841> I get most of the stations 'normal' stations with the tower ont he grojund
07:18 PM lcnc-relay: <skunkworks8841> ground
07:24 PM roycroft: so far i get zero stations with my little rooftop antenna
07:25 PM roycroft: my lean-to shed at the old house is completely deconstructed and there are no traces left of its existence other than some concrete pads that supported some 4x4 posts
07:26 PM roycroft: and i'm about ready to put together the metal shed a the new house that i'll use for lawn and garden stuff
07:26 PM roycroft: i'll get back to the tv antenna after that
07:27 PM roycroft: arguably, while i have all these other projects going on, i have no time to watch tv anyway
07:27 PM lcnc-relay: <skunkworks8841> lol - I hear the ex asking 'why are you working on that?'
07:28 PM roycroft: some quality downtime to unwind is actually really beneficial
07:28 PM roycroft: it makes one more productive
07:29 PM roycroft: my metal shed is getting installed on a concrete slab that's attached to the back of my house
07:29 PM roycroft: but if i installed it right at the edge of the slab, there would be like 6" between the shed and the house
07:29 PM roycroft: so i'm extending the slab with a 4x6 and a 4x4, so i can gain another 7"
07:30 PM roycroft: 13" clearance is a lot better than 6"
07:30 PM roycroft: i just finished installing the 4x6 with some long concrete anchors
07:30 PM roycroft: the 4x4 will attach to the 4x6 with some lag screws, so that should go pretty fast
07:31 PM roycroft: kind of a funky setup, but i do not want to deal with pouring concrete right now
07:31 PM roycroft: and it's just a shed for shovels, rakes, lawn mower, etc.
07:32 PM * roycroft will probably put his belt grinder in the shed for now, though
07:32 PM roycroft: and if there's room, i'll store my welders there instead of at the storage unit
07:34 PM * roycroft has cooled off enough now, and goes out to install the 4x4
07:56 PM Tom_L: skunkworks, will all that clear the tree?
08:07 PM lcnc-relay: <skunkworks8841> it will be close..
08:08 PM lcnc-relay: <skunkworks8841> it will be pointed away when I run it up
08:08 PM lcnc-relay: <skunkworks8841> everything is hooked up. I have to mount the access point - but other than that.
08:14 PM lcnc-relay: <skunkworks8841> (if you mean the pole that the antennas are mounted to - that was already run up all the way past the tree)
08:20 PM Tom_L: no, with the antennas
08:26 PM lcnc-relay: <skunkworks8841> I think it will be close - but I think it will be fine. I will video it 😉
08:27 PM lcnc-relay: <skunkworks8841> roycroft: cool!
08:40 PM roycroft: skunkworks: i asked you this the other day, but i did not see your response - i don't know if you did not see it or if i missed your answer
08:40 PM roycroft: you said you have two antennas oriented 90 degrees to each other
08:41 PM roycroft: do you combine their signals on a common coax or do you switch between them?
08:41 PM roycroft: there are two repeaters in the town i live in, about 140 degrees apart from each other from where i live
08:41 PM roycroft: maybe two antennas would make sense for me
08:52 PM lcnc-relay: <skunkworks8841> my plan is to combine them - I was very consciences of making the 2 coax exactly the same length
08:53 PM lcnc-relay: <skunkworks8841> if that doesn't work to my satisfaction - I may buy a antenna combiner (powered with smarts)
08:54 PM lcnc-relay: <skunkworks8841> or - I might find out that 1 antenna gets me everything I need and the second will be a backup..
08:54 PM lcnc-relay: <skunkworks8841> roycroft: ^
08:54 PM Tom_L: does that tower get grounded?
08:54 PM lcnc-relay: <skunkworks8841> yes - 3 ground rods..
08:54 PM Tom_L: not sure how that works on towers
08:54 PM lcnc-relay: <skunkworks8841> well - 4 with the electrical box...
08:55 PM Tom_L: but i was standing near a radio tower once when lightening hit it and i watched it disapate down the cable thru the insulators
08:55 PM lcnc-relay: <skunkworks8841> you are supposed to at a minimum ground each leg
08:55 PM lcnc-relay: <skunkworks8841> cool!
08:56 PM lcnc-relay: <skunkworks8841> and scary
08:56 PM lcnc-relay: <skunkworks8841> https://jauriarts.org/_matrix/media/v3/download/jauriarts.org/EZGKTYXpywEMpfRGCWTtreRG/PXL_20240810_190416530.jpg
08:58 PM lcnc-relay: <skunkworks8841> https://jauriarts.org/_matrix/media/v3/download/jauriarts.org/qNACSzGCxGQsRpOfLldePTOp/who_Camera_1723341087518.jpg
08:58 PM lcnc-relay: <skunkworks8841> lol - that is the camera currently
08:58 PM Tom_L: glad you clarified that
08:58 PM lcnc-relay: <skunkworks8841> I think it is pointed mostly towards the ground
09:02 PM roycroft: thanks
09:03 PM roycroft: my current plan is to get one channel
09:03 PM roycroft: and then i'll work on the second one
09:03 PM roycroft: so let me know how it goes
09:03 PM lcnc-relay: <skunkworks8841> I will
09:04 PM lcnc-relay: <skunkworks8841> If things go well - tomorrow the tower will be vertical.. Or a pile of scrap on the ground
09:04 PM * roycroft just heard thg on npr saying "i will let them hold their convention", referring to the democrats
09:04 PM * roycroft wonders how tfg thinks he could prevent that
09:04 PM roycroft: i want to see it vertical!
