12:19 AM Wolf__: i modded a noga super cool to work as a fog buster
12:47 AM XXCoder: cool
12:47 AM XXCoder: I saw few systems that can be used as mist cooler
12:48 AM XXCoder: ItsFlipp: you mean removal of mist from coolant spraying?
12:48 AM XXCoder: work few machines has em and its quite nice
12:49 AM Wolf__: fogbuster is a brand
12:49 AM XXCoder: oh. when i see fog and buster I was thinking more removal of mist than add
12:49 AM XXCoder: robo machines insides do get foggy if mist remover isnt running
12:52 AM Wolf__: fogbuster works by spitting the coolant out vs spraying it out via venturi and turning the coolant in to vapor
12:52 AM XXCoder: makes sense
12:54 AM Wolf__: https://i.imgur.com/6h18AtY.jpg coolant in pressure bottle and fed via a pickup tube in the jar
12:55 AM XXCoder: yeah looks familiar lol
12:55 AM XXCoder: been few years since last seen one
12:55 AM Wolf__: yeah, I made that 3 yrs ago
01:00 AM XXCoder: old job had few of those
01:00 AM XXCoder: cnc router (hugeass one) and couple manual/=automatic manual mills
02:53 AM Deejay: moin
02:53 AM XXCoder: morning
03:17 AM gloops: surely a base for a cnc mill https://www.ebay.co.uk/itm/Junior-Whitehead-WOODWORKING-MORTICING-MACHINE/392219765294?
03:18 AM XXCoder: dunno i see some odd features
03:18 AM XXCoder: maybe grinder setup
03:19 AM XXCoder: it might be missing many parts
03:19 AM gloops: well the xy is there, could move a spindle up and down on rails for the z
03:20 AM XXCoder: vertainly needs lots love
03:20 AM XXCoder: so much rust
03:20 AM XXCoder: probablky need strip it all way down
03:21 AM gloops: £20 lol, would have to spend a bit to get to that stage building something with steel or extrusions - and probably wouldnt be as solid
03:22 AM gloops: i wont be getting it anyway
03:29 AM XXCoder: dunno
03:41 AM gloops: https://www.youtube.com/watch?v=PZvxUXqjJfE&fbclid=IwAR33Vxd8CaHEVzeRutrL2ZiRe_XEJ1N3gpEpcuaVuuyEWJZp5nwwHApZoz4
03:41 AM gloops: someone asking if linuxcnc can do that
03:42 AM gloops: easy
04:12 AM jthornton: morning
05:39 AM sensille: hm, after i paused the program, the offsets were completely off. is this expected?
06:28 AM jthornton: no
06:58 AM Tom_L: morning
07:02 AM jthornton: morning
07:11 AM Tom_L: 30, Hi 53
07:11 AM Tom_L: warming up a bit today
07:29 AM jthornton: same here today and tomorrow
07:35 AM jthornton: hmm file manager died
08:07 AM sensille: oh, maybe it was because i pressed the cursor keys during pause
08:14 AM flyback: going to go negative next week
08:14 AM flyback: partially fixed dad's snowblower, doing more work later
08:18 AM sensille: might need to split the program to be able to do a manual tool change in the middle
08:55 AM jthornton: if you have to touch off each tool only have one tool per program so you can touch off before running
08:58 AM sensille: yes, seems like i can't jog/touch off even when the program pauses for manual tool change
09:09 AM Tom_L: there's always 'run from line' if that helps
09:20 AM * sensille tries touch off by multimeter
09:35 AM sensille: Loetmichel: do you use ball end mills?
09:35 AM Loetmichel: sensille: sometimes
09:38 AM sensille: is there a good way to roghen with a flat mill and finish with a ball end mill?
09:38 AM jthornton: split the program into two parts
09:38 AM sensille: z touch off after the change seems to be very sensitive
09:39 AM jthornton: is that a different problem?
09:40 AM sensille: if i do all with one end mill, being off by 0.1mm on z isn't normally really a problem
09:40 AM sensille: but when going to a ball end mill z is really critical
09:41 AM jthornton: are you saying you can't touch off Z accurately?
09:41 AM sensille: i'm trying to mill some slopes
09:41 AM jthornton: new problem?
09:41 AM sensille: basically yes. but i'm not sure if i have to touch off ball end mills the same way
09:42 AM sensille: everything one problem
09:43 AM sensille: the core might be that i can't touch off Z precisely, or that i touch off the ball end mill wrongly
09:43 AM jthornton: if you touch off the tools to the tool table and use a fixed point to do so then you only touch off the material with tool 1
09:44 AM sensille: the tool change is manual and not reproducible
09:44 AM jthornton: I assume some type of collet holder in the spindle?
09:44 AM sensille: yes
09:44 AM jthornton: right so only touch off tools to some fixed place like the top of the table
09:46 AM sensille: i see the sense in that
09:46 AM jthornton: https://www.youtube.com/watch?v=VmRUJk0ptN4
09:46 AM sensille: and touching off with a multimeter is fine?
09:46 AM jthornton: that is me touching off a tool in my lathe
09:46 AM jthornton: I've never done that with a multimeter
09:46 AM * jthornton wanders off to find a keyboard for the RPi
09:47 AM sensille: i've tried that method, but can't get <0.1mm with that
09:50 AM sensille: hm. or my current problem is that i'm using f360 plain wrong
09:55 AM jthornton: I get < 0.001" that way so maybe your just doing that wrong
09:57 AM sensille: probably
10:00 AM XXCoder: know what sucks?
10:01 AM XXCoder: waking up because need to go to restroom and thristy
10:01 AM XXCoder: dang 8 am :(
10:01 AM jthornton: 10am
10:01 AM Deejay: go to bed again and sleep some mooaar hours :)
10:02 AM XXCoder: yeah as soon as im not as thristy
10:06 AM Jymmm: shoves a garden hose down XXCoder's throat
10:07 AM * XXCoder shoves another one in jymmm, but not same hole
10:07 AM Jymmm: XXCoder: No thanks, I'm not thirsty
10:08 AM XXCoder: its extreme colon cleaseing
10:09 AM Jymmm: XXCoder: Nope, gotta buy me dinner first
10:09 AM XXCoder: well i certainly didnt want the free drink either but there ya go
10:10 AM Jymmm: you said you were thristy
10:10 AM XXCoder: yep have cup of water with me already lol
10:34 AM fragalot: hey
11:37 AM fragalot: I wonder if one could make a smelting furnace out of that 'starlite' material
11:38 AM XXCoder: problem is fake starlite is made from material that decaus
11:38 AM fragalot: true
11:38 AM fragalot: just got curious when I saw the hydraulic press channel go at it with a plasma torch
11:39 AM fragalot: and that still didn't burn through an 8mm thick piece
11:40 AM fragalot: lol, later on in the same video they use it to make a little arc furnace.. Guess that answers my question
11:40 AM XXCoder: did real starlite decay too?
11:40 AM fragalot: probably
11:40 AM XXCoder: i wonder if thats why guy was so controlling of samples, it would decay of shipped somewhere
11:41 AM fragalot: I'm sure there's more of a reason than "I didn't want to tell them" why NASA didn't use it
11:42 AM XXCoder: yeah
11:52 AM Tom_L: when done you can eat it for a snack
11:52 AM XXCoder: lol
11:53 AM Tom_L: Nicola McDermott, Ward's youngest daughter, stated that Starlite is 'natural' and edible, and that it has been fed to dogs and horses without ill effects.
11:59 AM XXCoder: it may indeed be very close to what that guy acciently re-discovered
02:34 PM The_Ball: I'm spending a couple of weeks here in the states before returning to Europe, any tips on where I could hunt for a renishaw omp?
02:36 PM skunkworks: HGR Industrial Surplus maybe?
02:36 PM JT-Shop: ebay
02:37 PM skunkworks: Well - a couple weeks should be enough to get something like that delivered..
02:37 PM JT-Shop: https://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=renishaw+omp&_sacat=0
02:37 PM skunkworks: The_Ball: where are you?
02:38 PM skunkworks: boy those are expensive
02:39 PM JT-Shop: new ones are crazy expensive
02:40 PM The_Ball: skunkworks, I'm visiting Boston for a week, then a couple of weeks in Florda Tampa
02:54 PM CaptHindsight is now known as InvisibleManinth
02:54 PM InvisibleManinth is now known as InvisibleSkyMan
03:16 PM InvisibleSkyMan: Google search "most expensive touch probe" Result: What is a Renishaw probe
03:18 PM InvisibleSkyMan is now known as CaptHindsight
03:23 PM gloops: the most expensive probe is one bought that doesnt havent any work to do
03:24 PM gloops: a 2k probe is cheap if its making 1k a day
03:24 PM syyl_: haha
03:24 PM syyl_: yes
03:25 PM syyl_: and a haimer doesnt make sense if you are clumsy enough to break a tip a day
03:25 PM gloops: im into cutters where if i drop one i just get another one out of the box
03:26 PM CaptHindsight: nope you can't philosiphize expensive
03:30 PM gloops: yes thats another for 'The Engineers guide to the galaxy'
03:34 PM CaptHindsight: 2 > 1, convince me I'm wrong
03:35 PM fragalot: syyl_: so use a tschorn instead.
03:36 PM fragalot: CaptHindsight: genocidezs?
03:37 PM fragalot: government shutdowns?
03:40 PM CaptHindsight: must go outside to examine strange ball of fire in the sky
03:41 PM fragalot: syyl_: I found those inserts you seem to like. https://www.shop-apt.co.uk/stock-clearance.html
03:42 PM Deejay: gn8
03:44 PM syyl_: oh interesting
03:44 PM syyl_: i finaly found out who made those i got
03:45 PM syyl_: they are kenametal inserts
03:45 PM fragalot: I've bought a few boxes from apt
03:45 PM fragalot: they're not razor sharp out of the box, but they do cut well
03:46 PM syyl_: hmm
03:46 PM syyl_: the kenametal are ridicioulus sharp ground, especially for a insert for steel-machining
03:47 PM fragalot: these are what you'd expect from an "as baked" insert
03:48 PM syyl_: with the price they are very appealing ;)
03:48 PM fragalot: indeed they are :D
05:08 PM gloops: https://www.facebook.com/john.olthafer/videos/2245094339082323/
05:09 PM gloops: think i do something with the exposed screw heads, but otherwise looks addictive
05:24 PM jthornton: geez I have to reflash motioneyeos to change the wifi password lol
05:30 PM * jthornton notices that motioneye has some of the worst documentation he has seen
05:33 PM jdh: I have some TIG power supplies with voluminous documentation, but seemingly written by an expert who leaves out parts needed by non experts.
05:35 PM jthornton: I try to write documents as if I know nothing about it
05:37 PM jthornton: I wonder if my last edit will work for the chicken door?
05:38 PM jdh: I try to do the same, but I know that I will leave out things I feel are obvious
05:39 PM jthornton: I tend to leave out the obvious after a bit of explaining the obvious
05:43 PM jthornton: geez finally got the motioneyeos camera to work
05:44 PM Tom_itx: required reflashing just for a password change?
05:44 PM jdh: paid $18k to have a super special arc starter added. It strikes an arc pretty much anywhere other than across the 0.040 gap to the work.
05:44 PM jthornton: yea the wpa_supplicant.conf is owned by root
05:45 PM jdh: then paid $6k to have the super arc starter removed and replaced with the plain one.
05:45 PM jthornton: damn
05:45 PM jdh: strikes fine in argon. we use helium
05:46 PM jthornton: Tom_itx: even more crazy is if it does not connect to the LAN it just keeps rebooting lol
05:46 PM jthornton: I use fart gas...
06:01 PM XXCoder: man
06:02 PM XXCoder: feels like i woke up from dead
06:04 PM jthornton: had a bad day sleeping?
06:04 PM XXCoder: yeah
06:04 PM XXCoder: tired earlier than usual so slept at 2 am
06:04 PM XXCoder: woke up at 7 am couldnt sleep tipp 9
06:04 PM XXCoder: till
06:04 PM jthornton: you work tonight?
06:04 PM XXCoder: then finally woke up now at 3:30 pm
06:05 PM XXCoder: thankfully no
06:06 PM jthornton: 6pm here time to wander upstairs
06:24 PM XXCoder: yayn lol
07:38 PM Rab: Okay everybody, time to upgrade: https://www.crowdsupply.com/good-robotics/wi-fi-stepper
07:43 PM ziper: i actually used a die
07:43 PM ziper: usually they just sit neglected, next to the taps
07:46 PM Rab: ziper, used it for making threads, or cleaning threads?
07:47 PM ziper: cutting. had a 2.5mm rod with m2.5 threads that snapped. only had a 3mm rod, ground down the ends by hand on a grinder and the cutting actually went rather well
07:58 PM jdh: ziper: you do carbon stuff?
07:58 PM ziper: yeah
07:59 PM jdh: I want to mill a slot in some carbon bike bars. any suggestions?
07:59 PM ziper: not yet. so far i'm just doing repairs, should be actually doing manufacturing in a couple months
08:00 PM jdh: repairs on what?
08:00 PM ziper: one operation of which would be slitting a ~24 inch long ~inch high slot through solid carbon
08:00 PM ziper: boats
08:00 PM jdh: do the cut fibers need to be sealed?
08:02 PM ziper: ideally, but depending on the application not necessarily
08:02 PM ziper: do you have a picture of diagram of what you need to do
08:03 PM jdh: no. maybe 4mm x 8mm slot cut in the side of handlebars
08:03 PM jdh: or a 5mm hole might be sufficient
08:03 PM ziper: abrasive disk?
08:04 PM jdh: end mill
08:04 PM jdh: or just drill
