04:49 AM -!- #linuxcnc mode set to +v by ChanServ
04:49 AM JT-Cave: morning

08:47 AM pcw--home: JT-Cave: found a bug in mesact: 7I95 SSR names are wrong (they have "output" rather than "out" in their names)
08:47 AM JT-Shop: thanks I'll fix that
08:48 AM pcw--home: all ssr pins (on any card) use "out"
08:50 AM pcw--home: unfortunately most of my test systems are too old (mint 20 )to run mesact
08:50 AM JT-Shop: darn
08:53 AM pcw--home: I have one (mint 21) that works
08:56 AM JT-Cave: it needs python 3.6 and pyqt 5.15
08:57 AM JT-Cave: prob the pyqt 5.15 is the issue with old os's
08:57 AM pcw--home: The forum guy with the limit issue might have been helped if "Max Vel" were "Max Vel (IPS)" not sure if the will fit...
08:57 AM JT-Cave: let me see
08:58 AM JT-Cave: there is mouse hover description but I can change the labels when units are selected
08:59 AM JT-Cave: I do that on the settings tab now
09:00 AM pcw--home: Its a really common error for people to mix up IPS/IPM and the metric equivs with LinuxCNC setup
09:00 AM JT-Cave: https://pasteboard.co/16KthIptpS7V.png
09:01 AM JT-Cave: actually when you select units is shows up in the line edit what the units are
09:01 AM JT-Cave: https://pasteboard.co/NQlcPJTsVP3a.png
09:03 AM pcw--home: That looks good, as long as there is a reminder
09:03 AM pcw--home: I wonder what is needed to get pyqt 5.15
09:03 AM JT-Cave: I think the problem with that method is it disappears after you enter a value
09:03 AM JT-Cave: https://pasteboard.co/AiRb3FJkWvBw.png
09:04 AM JT-Cave: PyQt5 Version 5.15.0 or newer (QTabWidget.setTabVisible() Debian 11 or up)
09:05 AM bjorkint0sh: https://www.simplethread.com/what-i-learned-about-software-from-building-a-chicken-coop/
09:05 AM * JT-Cave goes to lay down for a bit... still not feeling chipper
09:06 AM JT-Cave: I had a suffix before but it made it difficult to enter a value as you had to double click
09:08 AM JT-Cave: pcw--home, I do have room under the axis items for a description label and that won't increase the size of the gui
09:13 AM i_like_linux: What do you all use to connect your PC to a CNC machine? Do you use a UC400ETH, or would you recommend a parallel port instead? If the latter, is the best alternative to purchase a new motherboard with a parallel port if i dont have one?
09:14 AM JT-Cave: https://pasteboard.co/JUioAifklLGx.png
09:20 AM pcw--home: Probably not a bad idea to have the unit labels. Sorry you're not feeling well, take it easy...
10:02 AM Roguish: well, sunny and chilly. but rain coming later in the weekend......
10:28 AM roycroft: the appraisal on the new house just came back, and it appraised at way over what i offered, so now it's down to the final underwriting
10:28 AM roycroft: if things go as anticipaed i may close next week
10:38 AM lcnc-relay: <skunkworks8841> Nice!
10:41 AM roycroft: yeah, except the moving part is not going to be fun
10:41 AM skunkworks: You have a nice diesle truck..
10:41 AM roycroft: and my shop will be tiny at first
10:41 AM roycroft: i'm still not sure how i'm going to deal with that
10:42 AM skunkworks: are you going to build right away?
10:42 AM roycroft: there's a place in the town where i'm moving that has container storage for rent
10:42 AM roycroft: yes, as soon as possible
10:42 AM roycroft: so i'm thinking i'll store half my shop in a container while i build the addition
10:42 AM roycroft: and hopefully i'll have the new shop done by the end of the summer
10:43 AM roycroft: at least framed up and closed in
10:43 AM roycroft: i may do electricity and interior walls/insulation later
10:44 AM roycroft: i was going to do the whole shop build myself, but i'm thinking now that i'll do the excavation and form work for the foundation/slab myself, but hire out the actual concrete work
10:44 AM roycroft: which will cost more, but it will be a better job
10:44 AM roycroft: and realistically it takes at least three people to pour a slab properly
10:45 AM skunkworks: floating slab?
10:45 AM roycroft: if i still had my contractor's license i'd just hire a couple helpers, but i haven't had that in decades
10:45 AM roycroft: i think '89 was the last year i had a contractor's license
10:45 AM roycroft: i want to pour the slab and foundation together
10:46 AM roycroft: keep in mind that the frost line here is right about at the surface, so the foundation can be really shallow
10:46 AM skunkworks: how deep do you have to go in your regeon?
10:46 AM skunkworks: lol - nice
10:46 AM roycroft: i'm planning on 24"
10:46 AM skunkworks: we are around 4ft
10:46 AM roycroft: which is deeper than is really needed
10:46 AM roycroft: but it's hard to do it much more shallow than that
10:47 AM roycroft: and i've also decided for sure to build with 10' walls
10:47 AM roycroft: since the shop will be small, that additional headroom will allow for more storage
10:47 AM skunkworks: that is what I did my garage at the other house.
10:47 AM skunkworks: it is nice
10:48 AM roycroft: and instead of a truss roof i'll stick frame it, so that i can have a little bit of attic space
10:48 AM skunkworks: barn trusses... :)
10:48 AM skunkworks: *room in truss
10:48 AM roycroft: yeah, possibly
10:49 AM roycroft: i'll be dealing with a pain in the butt building inspection service - i've dealt with them before
10:49 AM roycroft: they make it difficult to use any but the most conventional building methods
10:49 AM Roguish: roycroft, good luck with the house....
10:49 AM roycroft: i wanted to build a timber frame shop, but i don't want to go through the headaches of getting it approved and inspected
10:50 AM roycroft: even with stamped engineering drawings they would make it difficult
10:50 AM roycroft: thanks, roguish
10:50 AM roycroft: after the appraisal came in it was pretty much a done deal
10:50 AM roycroft: i'm just waiting for underwriting to finish their work
10:50 AM roycroft: i've already initiated money transfers for escrow
10:50 AM skunkworks: dad used to make all of his trusses.. Until the addon to the shop..
10:51 AM roycroft: the shop will be l-shaped, so there will be a valley that needs to be stick framed anyway
10:51 AM skunkworks: it was nice to have the trusses delivered and set in place.. lo'
10:51 AM skunkworks: lol
10:59 AM roycroft: yes, that would be nice, but i don't think it will work for me, given the hip and valley thing and the expense of the trusses
10:59 AM roycroft: i haven't framed a roof in decades, though - it's going to be a relearning experience
10:59 AM roycroft: but i think it will be fun
11:00 AM roycroft: and it will be the first hip roof i've built for myself
11:00 AM roycroft: and the last one, i hope :)
11:02 AM roycroft: it's still going to be tight on space, and i don't think i'll have room for a stand-alone cnc router, so i'll probably have to go back to my over/under router design that was working on earlier
11:02 AM roycroft: but that's ok
11:03 AM roycroft: i will have room for an assembly table, which i don't have now, and which will be really really nice
11:29 AM JT-Cave: pcw--home, https://pasteboard.co/m0I9sqU9G4o7.png
11:29 AM JT-Cave: ipm is automagiclly updated
11:33 AM pcw--home: That's great, hard to mess that up
01:26 PM lcnc-relay: <satiowadahc#0> Does mesa have a limit on how far the ethernet cable to it can run??
01:57 PM Unterhaus_ is now known as Unterhausen
02:02 PM Unterhausen: I was just looking through my stuff and found a dc motor drive with the cover off. On further inspection, one of the output devices is exploded in 3 pieces
02:02 PM Unterhausen: peeled back like a banana peel
02:03 PM Unterhausen: don't know if it's worth fixing, it has no feedback at all
02:26 PM XXCoder: ethernet specs is 1 km for normal networking use. I dont know what it would be like on MESA
02:27 PM XXCoder: errm misremembered, its 100m
02:30 PM lcnc-relay: <skunkworks8841> wow - there certainly is a pucker factor relying on freecad cam..
02:32 PM lcnc-relay: <skunkworks8841> https://jauriarts.org/_matrix/media/v1/download/jauriarts.org/uxtjySQyJLHyyjZjrfReIpZi
02:32 PM lcnc-relay: <skunkworks8841> it sounds as loud as it looks
02:33 PM XXCoder: so, perfectly silent? ;)
02:33 PM lcnc-relay: <skunkworks8841> too much tool stick out - but it will probably work ok
02:33 PM XXCoder: seem to be cutting well. I dont see any chitter
02:33 PM XXCoder: oh looked closer. ow
02:33 PM XXCoder: some heavy chatter there
02:34 PM lcnc-relay: <skunkworks8841> yep.. but this is rough cut.. so eh
02:34 PM XXCoder: will it have finishing pass?
02:34 PM XXCoder: ok
02:34 PM lcnc-relay: <skunkworks8841> 15ipm
02:34 PM XXCoder: im bit concerned about rubbing there
02:35 PM XXCoder: did you add relief to endmill?
02:36 PM lcnc-relay: <skunkworks8841> https://jauriarts.org/_matrix/media/v1/download/jauriarts.org/rKTBlzIxzkLopELJjSlrzNBT
02:36 PM lcnc-relay: <skunkworks8841> needed that stick out
02:36 PM XXCoder: yeah, thats when relief grind is best used
02:37 PM XXCoder: so shaft thats not cutting isnt also touching part and pushing tool out a tiny bit
02:37 PM lcnc-relay: <skunkworks8841> oh sure.. if you have one.. lol
02:37 PM XXCoder: no grinder?
02:38 PM XXCoder: I suppose if have lathe can always spin it and hand grind it so it have tiny amount of material removed so it dont touch part
02:39 PM XXCoder: it takes very little
02:39 PM lcnc-relay: <skunkworks8841> oh sure.. but I am impatient
02:39 PM XXCoder: :)
02:39 PM XXCoder: it is one of ponental sources of chatter and noise
02:40 PM XXCoder: longest stickout I ever used was 1/8 endmill. it was 4 inches long to skip hitting the boss
02:41 PM XXCoder: it had heat strunk holder too so it was few inch more
02:41 PM XXCoder: thankfully it was fiberglass solid part not metal so not too bad lol
02:41 PM XXCoder: it eats tools though
02:43 PM lcnc-relay: <skunkworks8841> yikes
02:43 PM XXCoder: lol. it comes with special box of .75" endmill regrinds
02:43 PM XXCoder: some of em is like 0.68"
02:44 PM XXCoder: fiberglass eats tools so fast, so to save money they just regrind endmills
02:46 PM lcnc-relay: <skunkworks8841> oof - love linuxcnc..
02:47 PM XXCoder: hopefully didnt crash
02:51 PM lcnc-relay: <skunkworks8841> https://jauriarts.org/_matrix/media/v1/download/jauriarts.org/wRAwjxuQCBEuvvPatkmKbdGW
02:51 PM XXCoder: not bad looking
02:51 PM lcnc-relay: <skunkworks8841> not bad.. I can see freecads cam might be something I can actually use
02:51 PM XXCoder: that line is odd though
02:51 PM XXCoder: endmill rub mark?
02:52 PM lcnc-relay: <skunkworks8841> slowing it down at the corner helped
02:52 PM lcnc-relay: <skunkworks8841> I think so.. I think? it might have made 2 passes at the bottom - which if it moved over a little bit - could have rubbed oodly
02:52 PM lcnc-relay: <skunkworks8841> oddly
02:52 PM lcnc-relay: <skunkworks8841> probably should have looked at the gcode more
02:53 PM XXCoder: well thats pretty decent
02:53 PM lcnc-relay: <skunkworks8841> but - it didn't sound bad. just went around
02:53 PM lcnc-relay: <skunkworks8841> can't detect any taper
02:54 PM lcnc-relay: <skunkworks8841> I say this was a success
02:54 PM XXCoder: I would also, if its within tols
02:54 PM lcnc-relay: <skunkworks8841> now I need to bore a hole for the the ballnut
02:54 PM XXCoder: what do that line feel like anyway
02:55 PM lcnc-relay: <skunkworks8841> plus it also needs some other milling onit
02:55 PM lcnc-relay: <skunkworks8841> I can't feel them.. so pretty good
02:55 PM lcnc-relay: <skunkworks8841> The boring will be a couple drills and a spiral down with a mill.
02:56 PM lcnc-relay: <skunkworks8841> I can hand code that quicker - atleast currently lol
02:56 PM lcnc-relay: <skunkworks8841> mist coolant worked great!~
02:57 PM lcnc-relay: <skunkworks8841> yes - it did a slight smaller cut around the bottom - which doesn't work well with an endmill with no clearance...
02:57 PM lcnc-relay: <skunkworks8841> I wonder if you can turn that off.. It wasn't much - you can barely see the double path in linuxcnc
02:58 PM XXCoder: thats good. yeah its amazing how machining makes something really rough but its actually very close to being silk smooth
02:58 PM lcnc-relay: <skunkworks8841> the bore only has to go in 1.25 inches - I can use a shorter endmill
02:58 PM XXCoder: *looking
03:04 PM lcnc-relay: <skunkworks8841> wow - measures within a few thousands
03:04 PM lcnc-relay: <skunkworks8841> lol - that should work
03:06 PM XXCoder: sounds like it
03:06 PM XXCoder: last time I tried cam it was too hard to use for me lol
03:07 PM lcnc-relay: <skunkworks8841> That is why I haven't.. lol
03:08 PM XXCoder: what was cam like anyway
03:11 PM roycroft: cam's kind of uppity, and he uses way too much epoxy in his pieces
03:12 PM roycroft: https://www.youtube.com/watch?v=Og994GZ8oZg
03:12 PM roycroft: there's not even any wood in that piece
03:13 PM XXCoder: lol
03:16 PM JT-Shop: https://youtu.be/61l4JKsB1MI?list=PLH4J0b3KfGaNED27Y1kCvS_mSQtyXsiwC&t=595
03:16 PM JT-Shop: nuts, just use a hand saw
03:18 PM roycroft: i have a tentative appointment to sign paperwork tuesday morning and close at the end of the day
03:18 PM roycroft: things are getting real
03:18 PM JT-Shop: nice
03:19 PM roycroft: yeah, it's still kind of scary, but it will be good in the end
03:19 PM roycroft: the next three months will not be much fun
04:16 PM JT-Shop: https://youtu.be/7cOvK46JeiY?t=544
04:16 PM JT-Shop: I used that trick when I made the mortises on the mailbox
04:19 PM Tom_L: all done?
04:19 PM JT-Shop: yup, just need to install it
04:21 PM XXCoder: interesting trick
04:22 PM Tom_L: flex close to building a complete gui yet?
04:23 PM Tom_L: noticed quite a few updates..
04:23 PM JT-Shop: I'm having a problem with the qss files that's driving me nuts
04:23 PM JT-Shop: mesact has some updates
04:24 PM Tom_L: i'll build as soon as i run an errand
05:04 PM Tom_L: JT-Shop, PR#88 up
05:05 PM JT-Shop: ok thanks
05:09 PM Tom_L: is qss a style sheet?
05:09 PM JT-Shop: yup
05:10 PM JT-Shop: still thinking how to do the status update for buttons...
05:11 PM Tom_L: the code for those is in command.py?
05:12 PM Tom_L: most of them...
05:12 PM JT-Shop: well it would be in status.py
05:12 PM Tom_L: may somewhat depend on the button
05:13 PM JT-Shop: main issue besides the qss being ignored is how to set the estop style if emc causes a fault
05:13 PM JT-Shop: and what's odd is one config I have the qss works and another one it does not
05:13 PM Tom_L: on the flood/mist i check if somebody else changed it besides the button
05:14 PM JT-Shop: one thing I don't what to do is needless checking in status.py to keep the code fast
05:14 PM Tom_L: right
05:15 PM JT-Shop: thinker is a bit slow right now...
05:15 PM Tom_L: 2 ways to do something in code.. polled or interrupt
05:16 PM Tom_L: status is polled
05:16 PM JT-Shop: well you have to poll status to get an update
05:16 PM Tom_L: dunno how you would simulate an interrupt
05:16 PM JT-Shop: parent.status.poll()
05:17 PM JT-Shop: one thing is to have a semaphore and if it's different than last time do something
05:36 PM lcnc-relay: <skunkworks8841> https://jauriarts.org/_matrix/media/v1/download/jauriarts.org/XoLZRGmobqlTvatejzqbgapU
05:36 PM JT-Shop: nice
05:36 PM Tom_L: how long was that cutter?
05:36 PM lcnc-relay: <skunkworks8841> https://jauriarts.org/_matrix/media/v1/download/jauriarts.org/xDaKpNpJtJhBRvCjVOBtLGJW
05:36 PM Tom_L: not bad considering...
05:37 PM lcnc-relay: <skunkworks8841> no - let me look
05:37 PM lcnc-relay: <skunkworks8841> the flutes where
05:37 PM Tom_L: my kid brought me some with an undercut shank above the flutes
05:37 PM lcnc-relay: <skunkworks8841> 1.375
05:38 PM Tom_L: haven't used any yet
05:38 PM Tom_L: that's not too bad
05:38 PM lcnc-relay: <skunkworks8841> cut 1.7ish
05:38 PM lcnc-relay: <skunkworks8841> https://jauriarts.org/_matrix/media/v1/download/jauriarts.org/bRWwdzmVuTYNMmphRnHTNUIg
05:39 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/cutters/carbide_6flute2.jpg
05:39 PM Tom_L: those let you get away with that
05:39 PM lcnc-relay: <skunkworks8841> it did not like it.. lol
05:39 PM lcnc-relay: <skunkworks8841> I got yelled at for not undercuttin the shank.. 😉
05:39 PM Tom_L: haha
05:41 PM lcnc-relay: <skunkworks8841> https://jauriarts.org/_matrix/media/v1/download/jauriarts.org/grxhKPnhovfVzSAZonmESLZa
05:41 PM Tom_L: you could have ball nosed the whole thing flat :)
05:42 PM lcnc-relay: <skunkworks8841> few more machiniing operations.. and done
05:42 PM Tom_L: except the hole
05:42 PM Tom_L: probably taken 10x as long
05:42 PM lcnc-relay: <skunkworks8841> yah- seemed like the best way to do it.. for me
05:42 PM lcnc-relay: <skunkworks8841> it was done really quick..
05:43 PM lcnc-relay: <skunkworks8841> suprisingly quick
05:43 PM Tom_L: we machined a blower hat once with 8" cutters
05:43 PM Tom_L: talk about noisy
05:43 PM Tom_L: 8" loc
05:44 PM Tom_L: did the inside then filled it with ballast (pennies) to finish the outside
05:44 PM Tom_L: the bank wasn't so happy to count them on return
05:51 PM * JT-Shop calls it a night
06:56 PM roycroft: score
06:56 PM lcnc-relay: <skunkworks8841> https://jauriarts.org/_matrix/media/v1/download/jauriarts.org/mCZRGiqHECknnSAeXftAtyqx
06:56 PM roycroft: the house appraised at $40k more than i'm paying for it
06:56 PM lcnc-relay: <skunkworks8841> yah - that is a suprisingly good finish considering how it was machined
06:57 PM lcnc-relay: <skunkworks8841> Nice!
06:57 PM roycroft: it's not my ideal house by any means, but it was a real bargain, and that just confirms that it was
06:57 PM lcnc-relay: <skunkworks8841> Do you have a lot of equidy in your current house?
06:57 PM roycroft: so if i want to move back to the valley in a couple years i'll be pretty well set
06:58 PM roycroft: no, i don't, which is what makes it tough for me to move
06:58 PM roycroft: it will all work out in the end, though
06:58 PM roycroft: the money from the current house will go towards the new one and towards building the shop
06:59 PM lcnc-relay: <skunkworks8841> good
06:59 PM roycroft: the shop is going to be tight though - i really only have about $40/square foot to build it
06:59 PM roycroft: but i think i can at least frame it up and roof it for that, and work on insulation/interior walls/power over time
07:00 PM Tom_L: skunkworks, you can see how it was machined by the long chip marks :)
07:00 PM roycroft: we're doing a final walk-through tomorrow, and if the money arrives in time we close on tuesday
07:00 PM roycroft: and then my life is hell for a couple or three months :)
07:01 PM XXCoder: I call those long chips machine flooding chips
07:01 PM XXCoder: flooded the shop around machines because it clogged the coolant path lol
07:02 PM roycroft: i ran across an old copy of "american builder" magazine today at a thrift shop, and bought it
07:02 PM roycroft: the lead article is "gypsum products - their use in new construction and remodeling"
07:02 PM roycroft: it explains what sheet rock is, and how it can replace plaster in home construction
07:03 PM lcnc-relay: <skunkworks8841> https://jauriarts.org/_matrix/media/v1/download/jauriarts.org/OjacqtiVbvXTDSewrhryZQzF
07:03 PM XXCoder: thats a lot of tasty chips
07:03 PM roycroft: there's another article about getting fha loans for homes that cost more than $2500
07:04 PM XXCoder: lol
07:04 PM roycroft: the magazine dates to the truman administration
07:04 PM roycroft: an entertaining 75 cents it will be
07:05 PM roycroft: which is way more than it cost new
07:14 PM XXCoder: fun
07:14 PM XXCoder: pretty good myfordboy video today
07:14 PM XXCoder: it even has bit of humor, which is rare
08:13 PM lcnc-relay: <skunkworks8841> https://jauriarts.org/_matrix/media/v1/download/jauriarts.org/bFZbylTiNZrRkJishYZgxrMW
08:14 PM XXCoder: did you turn it around and make sharp corner?
08:14 PM lcnc-relay: <skunkworks8841> https://jauriarts.org/_matrix/media/v1/download/jauriarts.org/OCIDwWDenavbSgFhRyigChbR
08:15 PM XXCoder: bore seems nice. drill then boring?
08:17 PM lcnc-relay: <skunkworks8841> drill then mill
08:17 PM lcnc-relay: <skunkworks8841> yes - set it flat and made teh square corner
08:17 PM XXCoder: well it seems nicely done
08:17 PM lcnc-relay: <skunkworks8841> https://jauriarts.org/_matrix/media/v1/download/jauriarts.org/UKDZtoPihWfVUqBHjuBNqwnG
08:18 PM XXCoder: some finish work to make it look pretty and done lol
08:18 PM lcnc-relay: <skunkworks8841> sure.. but no one is going to see it.. except you?
08:19 PM XXCoder: thats right im going to break in and see it ;)
08:19 PM lcnc-relay: <skunkworks8841> this aluminum was hydraulic manifolds off the K&T., the thing rings...
09:09 PM roycroft: steve lawrence has left the building
10:43 PM XXCoder: finally got the cheap "portable ultrasonic" its just vibration motor
10:43 PM XXCoder: it might help keep water moving but certainly not ultrasonic
