12:17 AM veegee: theoretically rotary vane pumps seal better as they break in, yeah?
12:24 AM veegee: I'm thinking the vane and cylinder surfaces should smooth out

03:03 AM sensille: veegee: ok, now the spotify updated reached me too :-(
03:26 AM Bleepshop: Is 2 minutes a good time for the 3DChips.ngc to take to run?
04:05 AM Tom_L: morning
05:47 AM JT-Cave: morning
07:47 AM Tom_L: 40F this AM
07:47 AM gloops: warming up a bit here
07:53 AM JT-Cave: 50-60 and light rain, scattered out the last of the K31 on bare spots yesterday
08:02 AM Tom_L: i still have half a bag to spread
08:04 AM _unreal_: 40 LOL
08:04 AM _unreal_: its like 85 here
08:06 AM JT-Cave: I need to keep an eye out at Orscheln they sometimes put the 50 pound bag on sale
08:07 AM Tom_L: i got a contractor mix this time
08:08 AM JT-Cave: hmm it's on sale now, I hope it's still on sale Wednesday which is senior day and another 5% off
08:08 AM Tom_L: :)
08:12 AM JT-Cave: I got far enough along on the spoke machine to manually test the magazine indexing... took a short video of it
08:28 AM Tom_L: nice
08:29 AM JT-Cave: https://gnipsel.com/images/customers/Foxy/Top%20Cutter/
08:30 AM Tom_L: the gripper looks like the same parts
08:32 AM Tom_L: any problems with the first one since he's had it a while now?
08:45 AM JT-Cave: yea the gripper is on the machine itself so it's identical to the first one
08:46 AM JT-Cave: no, he loves it!
08:46 AM JT-Cave: he saw the video last night and said "Oh man that looks freaking sweet!"
08:51 AM Tom_L: great
11:03 AM Bleepshop: Igor! It's alive! https://www.youtube.com/watch?v=A88SfpItVgA
12:13 PM drdoc: Bleepshop: would that be "Eee-gor" or "Eye-gor"?
12:13 PM drdoc: Enquiring minds want to know.
12:28 PM Bleepshop: drdoc: That's e-gor till a 20K RPM twin-flute snaps then it might be eye-gore. ;D
12:29 PM drdoc: :-)
12:47 PM Bleepshop: I never got an answer last night. Is 2 minutes a good time for the 3DChips.ngc to take to run on a huge beast of a machine that shakes the floor when the gantry does a fast jog ?
12:48 PM * Bleepshop wonders if he could use the shopvac to blow sand in under that section of the floor as a support medium.
02:14 PM Rab: https://www.mcmaster.com/miniature-milling-machines/
02:16 PM Rab: Looks like a Pocket NC in an enclosure. The 3-axis machine looks vaguely familiar, but I can't place it...unsupported rail Make:r fare.
02:19 PM CaptHindsight: https://www.dudeiwantthat.com/gear/gadgets/nomad-desktop-cnc-mill.asp
02:20 PM CaptHindsight: the wood enclosure gives it that 70's vibe
02:20 PM CaptHindsight: and grandpa like repeatability
02:23 PM Rab: They have one in HDPE if you want a more futuristic aspect.
02:24 PM Rab: Repeatability at 0% Load: 0.003" to 0.005"
02:26 PM CaptHindsight: nothing but UHMW for me please
03:23 PM Tom_L: pretty sure the mrs wouldn't allow mine in the kitchen
03:26 PM Tom_L: Rab, drops to 0.03" to 0.05" at 10% load
03:26 PM JT-Cave: I'm pretty sure I couldn't get one of mine in the kitchen without a big crane and a hole in the roof
03:26 PM Tom_L: if you did, it might get auto delivered to the basement
03:27 PM JT-Cave: dunno I built the floor pretty stout
03:27 PM Tom_L: i wish Kenneth Maxon's site was still up. when he built his new shop there was a series of shots of him moving his bridgeport with a crane OVER his house and in the back door
03:28 PM Tom_L: they parked the crane on pads in the middle of the road and hoisted it over the house
03:29 PM CaptHindsight: slide the house off the foundation, lower shop tools into basement, replace house
03:42 PM Tom_L: might make you cry if the basement ever flooded
05:04 PM skunkworks: CaptHindsight: our current house was moved onto a new basement.. So certaily a possiblity... :)
05:05 PM Tom_L: skunkworks, yeah but i saw the size of your mill...
05:08 PM skunkworks: heh - I wonder if I could dig a K&T into the basement...
05:08 PM skunkworks: with the 60 tool tool chain.
05:09 PM Tom_L: might have to extend it into the back yard a bit

07:31 PM _unreal_: has anyone seen nogoddamnidea talking as of late?
07:31 PM _unreal_: or did he give up FINALLY
07:36 PM drdoc: jhe was on briefly yesterday
07:37 PM drdoc: I have a possibly silly question
07:37 PM drdoc: why will 60/40 solder not bond to 6061 Al?
07:38 PM drdoc: the aluminum is getting hot enough to melt the solder and there's boucoup flux
07:38 PM drdoc: also:
07:38 PM drdoc: I love this $5 300W iron
07:39 PM drdoc: not only does it move a lot of BTU, but if I ever have to fight a grizzly bear I can use it for a club.
07:39 PM -!- #linuxcnc mode set to +v by ChanServ
07:42 PM XXCoder: $5 wha
07:44 PM drdoc: XXCoder: I snatched a 300W Hexacon soldering iron a couple of months ago
07:44 PM XXCoder: ahh cool
07:44 PM drdoc: gov't auction, $5
07:45 PM XXCoder: i went to surplus before, it was great
07:45 PM XXCoder: billions of knifes lol
07:45 PM XXCoder: all captured at airport
07:45 PM drdoc: they're mostly online now
07:45 PM drdoc: but yeah. I have a gallon baggie of leatherman multitools I bought by the pound
07:46 PM XXCoder: nice
07:46 PM drdoc: and when I had a S&W MP9, I bought 5 magazines for it for $5-6 each over a few months
07:46 PM drdoc: the state surplus barn's right up the road
07:47 PM drdoc: that pistol was like a Chebby Vega
07:47 PM XXCoder: guns, i care much less
07:47 PM drdoc: you can buy all manner of performance parts for it, and even more bling
07:48 PM drdoc: but it's always still gonna be a Vega
07:48 PM drdoc: Congratlations, You have a sow's ear purse.
07:48 PM XXCoder: ?
07:48 PM drdoc: never heard of trying to make a silk purse out of a sow's ear?
07:49 PM XXCoder: i vaguely recall it but i forgot meaning
07:49 PM drdoc: you can try all you want and do whatever you want to it, but if you start with a pig's ear, you're never getting the silk purse
07:50 PM XXCoder: ag vega always sucks is what you mean?
07:50 PM drdoc: yes
07:50 PM drdoc: well, no
07:50 PM drdoc: Vega was actually one of the first decent US-designed compacts
07:51 PM drdoc: but it was designed to be cheap.
07:51 PM drdoc: small, lightweight, not all that rigid, not much leeway in the suspension & steering
07:52 PM drdoc: you could cram a big block V8 in it, and a lot of folks did
07:52 PM drdoc: but you couldn't really drive it any faster
07:53 PM drdoc: it was just too flimsy for that kind of oomph
07:58 PM roycroft: well, folks, it is an awesome day
07:58 PM drdoc: do tell!
07:58 PM roycroft: for today is the beginning of mojito season
07:58 PM roycroft: the earliest ever
07:58 PM drdoc: lol
07:58 PM roycroft: mojito season has never started here before may before
07:59 PM roycroft: but my mojito mint is almost exploding with growth
07:59 PM drdoc: well then
07:59 PM drdoc: better get right on that
07:59 PM * roycroft just made the first delicious mojito of the season, and is enjoying it
08:00 PM roycroft: fortunately i always have limes in stock
08:00 PM * drdoc has learned that you can't solder raw alunium
08:00 PM roycroft: and i had a bunch of club soda from last year
08:00 PM drdoc: as my Granddad would say
08:00 PM roycroft: i don't think aluminium is easy to solder
08:00 PM roycroft: iirc it oxidises while heating it up
08:00 PM roycroft: it's fairly easy to weld
08:01 PM drdoc: if it's possible, I haven't got the secret
08:01 PM roycroft: but when welding the heat is applied pretty instantly, and in an oxygen-free environment
08:01 PM drdoc: welding it's easy if you're tooled for it
08:01 PM roycroft: i don't know if there's a flux that will work for soldering it
08:02 PM drdoc: 's ok. I have some 2oz PCB that'll work
08:02 PM roycroft: it's easy to mig/tig weld
08:02 PM drdoc: yeah
08:02 PM drdoc: it's not terribly hard to braze if you have a big tank
08:03 PM roycroft: as long as you clean it within minutes, if not seconds, before soldering
08:03 PM drdoc: or I suppose I could go buy a set of official busbars
08:03 PM roycroft: that oxide layer forms almost instantly
08:03 PM drdoc: yup
08:03 PM roycroft: i am working on my gazebo today
08:04 PM roycroft: we had a hail storm last month that destroyed my patio gazebo top and my grill gazebo top
08:04 PM roycroft: they were those thin synthetic fabric tops
08:04 PM roycroft: i'm using the money from the insurance settlement to buy some wood and make wood tops for them
08:04 PM drdoc: nice
08:05 PM roycroft: which should withstand snow/hail storms better
08:05 PM * drdoc nearly spit out his teeth
08:05 PM roycroft: this is the second time my gazebos have been destroyed by weather
08:05 PM roycroft: it's stupid to scrap the frame because the fabric top is damaged/destroyed
08:05 PM drdoc: lowes, 8-way terminal block bus bar, looks like probably 15A total
08:05 PM drdoc: $433
08:06 PM drdoc: then I noticed the Qty 50 part
08:08 PM drdoc: yeah, but occasionally the adjuster's silliness is a good thing
08:10 PM drdoc: Survey says Lowes' bus bar is cheaper & easier than making them
08:10 PM drdoc: So mote it be
08:16 PM roycroft: i've some friends whom i haven't seem much in the past year
08:16 PM roycroft: as of tomorrow we'll all have our second jabs
08:17 PM drdoc: oh?
08:17 PM roycroft: so i'm wanting to have a get-together soon, but i need to get the gazebo fixed up first
08:17 PM drdoc: ah
08:17 PM drdoc: oops
08:17 PM roycroft: this is a "returning to something resembling normalcy and reconnecting with friends" project
08:17 PM roycroft: so it's very important to me
08:17 PM drdoc: amen to that
08:18 PM drdoc: the overlords are yowling for their dinner
08:18 PM drdoc: I hear and obey.
08:18 PM * roycroft just grilled some steelhead and veggies for dinner
08:44 PM Tom_L: drdoc, https://superiorflux.com/papers/TWJ.May.2018.Tech.Solder.Al.pdf
08:44 PM Tom_L: #1, you're not getting it hot enough

10:55 PM Bleepshop: Who's awake and semi-sober this Saturday night?
10:55 PM * Bleepshop is severely confused.
10:56 PM XXCoder: not me
10:56 PM XXCoder: im not semi-sober, or drunk
10:56 PM Tom_L: somewhat awake
10:56 PM XXCoder: tom dont count, hes not completely awake
10:57 PM roycroft: i only had one mojito, so i'd consider myself sober
10:57 PM roycroft: and i think i'm awake
10:57 PM Tom_L: 60 sec to ask or i'm out
10:58 PM Tom_L: trying to find audio solutions since this phone has no headphone jack now
10:58 PM Tom_L: don't want bt
10:58 PM Bleepshop: Got home?/limit? switches from the original setup at the right and front of the machine. Added one for minimum Z. Should I call thes my max limits for input because everything moves away from them when homing ?
10:58 PM Tom_L: i did find a usb c to 3.5mm adapter i may try
10:59 PM Tom_L: i set a max + limit for Z and set a soft limit for -z, no switch
10:59 PM Bleepshop: Tom_L: Look up the youtube vid on adding one to an iPhone. Process should be similar. ;D
10:59 PM Tom_L: it's a done deal already
11:00 PM Bleepshop: Ah. You already drilled the hole? xD
11:00 PM Tom_L: yeah the plug fits fine now
11:00 PM Tom_L: audio is a bit fuzzy though
11:01 PM Tom_L: use the right hand rule for your axis + - directions
11:01 PM Bleepshop: Can I use these as Max limits and then set soft limits for home away from them?
11:01 PM Tom_L: i send my table to the left front when homing
11:01 PM Tom_L: and z to the top
11:02 PM Tom_L: i suppose you can configure linuxcnc just about any way you wish
11:03 PM veegee: Yeah, they even give you the source code
11:03 PM veegee: for free!
11:03 PM veegee: like they _want_ you to change it up
11:03 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/NEW_MILL_SHOP_2.8.1/
11:03 PM Tom_L: knowing how mine homes, you can view the config there
11:03 PM Bleepshop: This is an old Acu-Cut with Front/Right/NULL. I added the z Minimum switch because I didn't want to trash another flex coupler.
11:04 PM Tom_L: after moving front right i move off those switches i think .050" and call that home
11:04 PM Tom_L: excuse me, front left
11:05 PM Tom_L: and as long as your cad knows where your machine is, you can do just about anything you want
11:06 PM Bleepshop: Yeah, That's what was confusing me... If I manually set Homes by toggling hte switches it'll load the 3DChips.ngc and run it with the Z scale set to .1 and everything moves the right directions I think.
11:07 PM Tom_L: not sure why you're worried about 3d chips
11:07 PM Tom_L: that's just how they programmed it, you just need an offset set for it
11:07 PM Bleepshop: I'm just using it for a G-code file. The ArcSpiral in the examples barfs like a freshman. LOL
11:09 PM Bleepshop: It ran in 2 minutes which looked good to me and the gantry was tracking with the onscreen toolpath. https://www.youtube.com/watch?v=A88SfpItVgA
11:09 PM Tom_L: i haven't payed much attention to their gcode examples to be honest
11:10 PM Tom_L: upi
11:10 PM Tom_L: you're not using axis right?
11:10 PM Tom_L: gmoccapy?
11:10 PM Tom_L: maybe i'm thinking of someone else
11:10 PM Bleepshop: gmoccapy. Yeah.
11:11 PM Bleepshop: It's been 30+ years since I needed to write G-code so I'm past rusty and somewhere close to corroded off. LOL
11:12 PM Tom_L: i haven't done any commercially for a while either
11:12 PM Tom_L: i did get my cad post working very well with linuxcnc though

11:12 PM Bleepshop: Last time I used it was to get a 4.0 in an 18 credit hour class.
11:13 PM Tom_L: i still use the cad cam i had from back then
11:13 PM Tom_L: old but effective
11:14 PM Tom_L: my kids both learned catia and one is taking mastercam class now
11:14 PM Tom_L: they kinda made me brush up on gcode a little
