01:17 AM JavaBean|new|2 is now known as JavaBean
05:54 AM JT-Cave-: morning
05:55 AM XXCoder: yo
06:13 AM _unreal_: taking my daughter to the water park today
06:13 AM _unreal_: sucks its an hour away :(
06:13 AM _unreal_: who can argue with BIG ass rides :)
06:32 AM Tom_L: morning
06:32 AM XXCoder: yo

08:57 AM JT-Cave-: not sure how to handle the arcs from the first loop out to the last loop if the pocket corner radius is large...
09:14 AM -!- #linuxcnc mode set to +v by ChanServ
09:21 AM Tom_L: you probably want to climb cut on a pocket too
09:26 AM JT-Cave-: it is doing a climb cut
09:37 AM JT-Cave-: I guess I could increment the radius of the corners each loop until it's the same as the pocket radius... the first loop can't be bigger than the woc
10:00 AM Tom_L: my bad... outside in
10:02 AM Tom_L: i usually do pockets inside out then you get a better wall finish unless you climb a cleanup on the wall
10:03 AM Tom_L: maybe you are... the big white dot makes me think that's the start point
10:14 AM JT-Shop_ is now known as JT-Shop
10:15 AM JT-Shop: start is the long line that ramps down to z cut level then goes back to the first small arc
10:16 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/JT-SHOP/pocket.jpg
10:16 AM JT-Shop: muggy as all get out outside... 15 minutes of shoveling compost and I'm sweating all ove
10:16 AM Tom_L: that's what sc does
10:16 AM JT-Shop: sc plunges in z?
10:16 AM Tom_L: i didn't set up a ramp but it would
10:17 AM JT-Shop: I need to take in account corner radius of the pocket
10:17 AM Tom_L: lemme radius the pocket
10:17 AM JT-Shop: k
10:18 AM Tom_L: it will do spiral, linear or zigzag
10:20 AM Tom_L: same pic.. refresh
10:20 AM Tom_L: the last cut is radius'd
10:21 AM Tom_L: and it added a ramp move at the start
10:21 AM Tom_L: since i changed the height of the profile
10:21 AM Tom_L: if your profile is drawn at Z0 that's what you get
10:21 AM Tom_L: draw your profiles at depth
10:21 AM Tom_L: (if you ever try it out)
10:23 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/JT-SHOP/pocket1.jpg
10:24 AM Tom_L: that was just by changing the profile depth from .250 to .500 and rerunning the pocket routine
10:24 AM Tom_L: you can adjust the depth of cut prior if you want
10:24 AM Tom_L: and allows for a finish allowance if you want that
10:26 AM JT-Shop: I read on a few tool maker sites that you want to keep the tool fully engaged when cutting a pocket, to do that you have to use rasius on the corners
10:27 AM Tom_L: it's probably better
10:28 AM * JT-Shop goes back to compost bin maintenance before the rains start but first some Kate Bush
10:28 AM Tom_L: how does onecnc handle it?
10:29 AM JT-Shop: let me see
10:29 AM Tom_L: it would be alot newer than mine
10:31 AM Tom_L: i noticed on my last pic i forgot to reverse the pocket cutout direction :)
10:32 AM Tom_L: you wouldn't have known it until you ran it
10:34 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/JT-SHOP/pocket2.jpg
10:34 AM Tom_L: suttle difference between pocket1 & 2
10:34 AM JT-Shop: square corners in onecnc
10:35 AM JT-Shop: for conventional
10:35 AM Tom_L: it's gonna be unavoidable in some cases
10:35 AM Tom_L: it couldn't be that big a deal or they both would have addressed it
10:36 AM JT-Shop: default is a bunch of arcs with straight lines at the sides... looks like cutting a bunch of air
10:37 AM Tom_L: even if i do a wall offset instead of a pocket it's square except the last cut
10:37 AM JT-Shop: cuts the material out CW then does a finish pass CCW
10:37 AM Tom_L: odd
10:38 AM Tom_L: takes more HP
10:39 AM Tom_L: lemme try something
10:41 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/JT-SHOP/pocket3.jpg
10:41 AM Tom_L: i gave the pocket large corner radius
10:42 AM Tom_L: in that case it does create corner radius to the point of the tool diameter
10:43 AM JT-Shop: yea I need to figure out how to increase the cut radius as it gets close to the side if the pocket radius is larger than woc
10:44 AM Tom_L: or start using that :)
10:48 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/JT-SHOP/test.txt
10:48 AM Tom_L: there's the output if that helps with the I & J on the G3
10:48 AM Tom_L: i offset the cutter radius distance
10:49 AM Tom_L: every 4th one would be the same corner
12:09 PM JT-Cave-: I think I need to calculate the radius based on the corner radius and distance to the wall
12:10 PM * JT-Cave- goes to take a nap and ponder that calculation
12:33 PM * Tom_L goes to finish fixin the dryer then a nap
02:27 PM JT-Cave-: https://gnipsel.com/images/emc/Screenshot%20at%202021-06-06%2013-56-59.png
02:29 PM Tom_L: getting better
02:29 PM Tom_L: are you calculating from the outside in?
02:30 PM Tom_L: it might error on that inside radius
02:46 PM Roguish_shop: JT-Cave-, hey, you're making great progress..........
02:48 PM Tom_L: Roguish, what you workin on today?
03:02 PM Roguish_shop: Tom_L, . just put a picture up on the matrix linuxcnc
03:03 PM Roguish_shop: what's the current best place to put pictures up?
03:09 PM JT-Cave-: Roguish_shop, did you try the facing one?
03:09 PM JT-Cave-: of course they will all be in one when done...
03:09 PM JT-Cave-: I just put them up on my web site cause imagebin.ca seems broken
03:09 PM JT-Cave- is now known as JT-Cave
03:10 PM JT-Cave: Tom_L, I start at the center and if not an even woc the first pass is less so the rest of the passes are full woc
03:30 PM Tom_L: yeah my matrix isn't working right aparently
04:41 PM JT-Shop: there is a small chance I'll see the top of my big work table tonight but it's beer thirty so it might slow down a bit
04:53 PM Tom_L: as long as i can see a small piece of mine, i'm ok
05:35 PM JT-Shop: one work table clean as a whistle... 7 to go
05:37 PM XXCoder: :)
05:38 PM JT-Shop: ain't gonna happen today lol
05:39 PM XXCoder: unless you have clone magic to make 5 more of yourself
05:40 PM JT-Shop: spoke lathe guy asked if I could clone myself and I told him I tried once but they came out 1/2 as good
05:40 PM XXCoder: ah china quality clone heh
05:40 PM JT-Shop: way better than that LOL
05:41 PM XXCoder: lol
05:43 PM Tom_L: spoke machine #2 up and running?
05:44 PM JT-Shop: not that I know of
05:44 PM JT-Shop: I'll visit there tomorrow to see if they have it setup and running in manual or not
05:44 PM Tom_L: i didn't know if you finished that one yet
05:45 PM JT-Shop: a buddy asked me if I could give him an estimate on building a cat bypass for the 998 spyder
05:45 PM JT-Shop: I'm finished building but still need to integrate the feeder to the spoke lathe
05:45 PM JT-Shop: I told him I don't give estimates any more
05:46 PM JT-Shop: the only thing for sure is I won't make one this month lol
05:46 PM Tom_L: heh
05:47 PM Tom_L: how's the shooting range goin now that it's been running a while?
05:47 PM JT-Shop: https://forum.linuxcnc.org/38-general-linuxcnc-questions/42773-software-not-talking-to-hardware-new-build#211364
05:47 PM JT-Shop: wtf is he talking about
05:47 PM JT-Shop: gotta go to the range tomorrow and troubleshoot a couple of lanes
05:48 PM Tom_L: nothing to do with linuxcnc for sure
05:48 PM JT-Shop: that's what I thought
05:48 PM Tom_L: m.2 is those onboard ssd plugins
05:48 PM Tom_L: dunno wtf he's trying to do with them
05:49 PM JT-Shop: me neither lol
05:52 PM JT-Shop: Tom_L, did you try out the G code generator facing part?
05:53 PM JT-Shop: https://gnipsel.com/linuxcnc/gcode/index.html
05:53 PM Tom_L: no
05:53 PM Tom_L: i'm not sure i've tried any of those yet
05:54 PM JT-Shop: it's only one now with all in one
05:54 PM Tom_L: don't have a linux box up in here right now
05:54 PM Tom_L: been trying to figure out if i have a MB problem or something else going on
05:55 PM Tom_L: got another one but it's got an i7 on it and won't run 32bit os
05:55 PM Tom_L: err win7 anyway
05:56 PM JT-Shop: still fighting that?
05:56 PM Tom_L: you're definitely filling a needed gap for routines
05:56 PM JT-Shop: thanks
05:56 PM Tom_L: haven't really fought on it much
05:56 PM Tom_L: i got a new wireless kbd and it's been pissing my mouse off
05:56 PM JT-Shop: LOL
05:57 PM Tom_L: trying to run them both from the same usb dongle
05:57 PM JT-Shop: I don't know what sparked me to clean the work table off...
05:57 PM Tom_L: separated them for now
05:57 PM Tom_L: i like the new kbd
05:57 PM JT-Shop: what did you get?
05:57 PM Tom_L: but it better shape up or it'll be out the door
05:58 PM Tom_L: https://www.logitech.com/en-us/products/keyboards/mx-keys-wireless-keyboard.920-009294.html
05:58 PM Tom_L: good feel to it
05:58 PM Tom_L: i got 3 pc's mapped to it
05:59 PM JT-Shop: dang
05:59 PM Tom_L: you can switch between them
05:59 PM Tom_L: i don't do it alot but sometimes
05:59 PM JT-Shop: it better be nice at $99
05:59 PM Tom_L: i got 3 :/
05:59 PM Tom_L: kid, wife and me
05:59 PM Tom_L: he needed one for mastercam as the laptop sucks for that
06:01 PM Tom_L: sitting next to it is a Northdgate omnikey and just to the left is a $5 chinacrap kbd
06:04 PM JT-Shop: time to lock up and head inside
06:54 PM Roguish_shop: definitely done for the day. just messed up a part. dang.
06:54 PM Roguish_shop: oh well, will remake tomorrow.....
06:54 PM Tom_L: oops
06:54 PM Roguish_shop: yeah. 2 threaded holes intersecting. and i stupidly forced the screws in....doh.
06:55 PM Roguish_shop: so, cleaned up and shutting down. beer and chips on the deck time..... see ya'll tomorrow.....

08:36 PM hotporksausage: Hi all
08:37 PM hotporksausage: I've been running 2.9 for about a year, parallel port/steppers
08:37 PM hotporksausage: I've finally got some servos, 7i96, 7i85S and a THCAD-10
08:38 PM hotporksausage: looking at download page latest stable is 2.8.1
08:38 PM hotporksausage: LinuxCNC 2.8.1 Raspberry Pi OS based on Debian 10 Buster
08:38 PM hotporksausage: is 2.8.1 only for RPi4?
08:38 PM CaptHindsight[m]: howdy
08:39 PM CaptHindsight[m]: no, but it's not as an ISO for x86, just an update
08:39 PM hotporksausage: ah I see, thanks
08:40 PM Tom_L: http://buildbot.linuxcnc.org/dists/buster/
08:40 PM hotporksausage: so would LinuxCNC 2.8.0 Debian 10 Buster PREEMPT-RT ISO be best option? I am building a plasma hence THC, and have 2x servos on X. I can't remember why I used 2.9 I think it was something to do with plasma support or gantry
08:41 PM Tom_L: 2.8.1 is the latest release
08:41 PM Tom_L: install the iso then do an update?
08:41 PM hotporksausage: perfect thank you
08:44 PM Tom_L: are you using an rpi4 or pc?
08:45 PM Tom_L: parport leads me to believe a pc
