02:07 AM Deejay: moin
02:37 AM memleak: hey Deejay
02:38 AM memleak: I see you a lot in here, what do you use linuxcnc for if you don't mind me asking?
02:41 AM Deejay: hey memleak. some years ago, i build my own CNC (mostly aluminum base). it is mostly used for cutting wood and plexiglass (PMMA).
02:43 AM Deejay: but i run it not very often ;)
02:44 AM memleak: ah ok, how much of a challenge was it for you to build your own?
02:47 AM Deejay: it was quite a big challenge, i never did something like that before. but i also learned a lot :)
02:48 AM memleak: heh i bet!
02:50 AM Deejay: :)
04:03 AM Tom_L: morning
04:27 AM JT-Cave: morning
07:32 AM -!- #linuxcnc mode set to +v by ChanServ
09:53 AM CaptHindsight: Ping
10:36 AM firephoto__ is now known as firephoto_
10:47 AM rdtsc_away is now known as rdtsc
10:47 AM rdtsc: Pong
11:01 AM _unreal_: fun times. thread milling 70 holes
11:01 AM _unreal_: I'm almost done building my wet jig basin
11:01 AM _unreal_: cant wait
11:01 AM _unreal_: all things WET milling are on the table
11:01 AM _unreal_: cant wait cant wait
11:02 AM _unreal_: and I have proven my new machine will handle stainless 316
11:02 AM _unreal_: just I HAVE to do it in flood
11:02 AM _unreal_: HAVE TO
11:04 AM _unreal_: I need only to finish threadmilling the holes, :( go out and get a new flat 1/4-20 3" BECAUSE I over cut one of the others and I dont have any more. the 2 in the middle through bolt with a seal to the table. and I need to install the train barb. and get a hose. once I have those I am in business to do any work. THOUGH I do need to run the plaining bit across the surface to 100% ensure the aluminum working plate is flat
11:04 AM _unreal_: cant wait cant wait
11:05 AM _unreal_: I already have jobs lining up.
11:05 AM _unreal_: wish I coulnd find a house and move faster
11:05 AM _unreal_: this everything contrasting at the same time issue is very frustrating
11:47 AM Deejay: hi
12:21 PM CaptHindsight: Howdy dj
12:22 PM rdtsc: And Cap'n is on land :)
12:29 PM JT-Cave: nap time here
12:38 PM _unreal_: threadmilling done YAY
12:38 PM _unreal_: just finished the build for the WET shoe
12:40 PM _unreal_: which was really just cutting the feeding tube to the right length and installing the spring, and aim set screw with a wing nut
12:40 PM _unreal_: may change it to a nylock
12:40 PM _unreal_: likely to vib free
12:41 PM _unreal_: all that is left is plaining the aluminu surface getting the one right size flat 3" machine screw. and installing the drain system and I'm in business
12:41 PM _unreal_: not sure what my first work peice will be
12:41 PM _unreal_: 316 steel or stone
01:53 PM rdtsc: ugghhh CAD Sketcher and BlenderCNC add-ons both are at python 3.11 but latest Arch Blender is 3.12 - so are incompatible
01:55 PM rdtsc: just tried hacking them to include hacked 3.12 wheels and manifests - no-go.
02:40 PM JT-Woodshop is now known as JT-C3_Shop
02:41 PM JT-C3_Shop: well the hateful job of cleaning off the frame is done
02:41 PM Tom_L: downhill from here
02:41 PM JT-Shop: yup
02:42 PM Tom_L: got the A frame parts cleaned yet?
02:44 PM JT-Shop: upper is painted
02:44 PM JT-Shop: lower is in the blast cabinet
02:48 PM JT-Shop: passenger side is done and the toe in roughly set
02:52 PM Tom_L: is there a way to tell what desktop is loaded if you're not sure?
02:53 PM JT-Shop: I don't know how to
02:54 PM Tom_L: must be mate, there are mate utilities installed
02:54 PM rdtsc: could try https://itsfoss.com/find-desktop-environment/
02:54 PM JT-Shop: echo $XDG_SESSION_TYPE
02:55 PM JT-Shop: hmm that just returns x11
02:55 PM rdtsc: ditto on Arch
02:55 PM Tom_L: nothing on this one
02:56 PM JT-Shop: LOL System > About Mate is a clue
02:56 PM Tom_L: does help if you spell it right
02:56 PM Tom_L: x11
02:57 PM Tom_L: i'm trying to figure out why in a folder the 'open terminal' option isn't available
02:57 PM Tom_L: to open a terminal in that folder
02:57 PM JT-Shop: let me get that for you
02:57 PM Tom_L: this is that RTAI build
02:57 PM rdtsc: debian?
02:57 PM -!- #linuxcnc mode set to +v by ChanServ
02:57 PM Tom_L: 12
02:58 PM Tom_L: it's not part of mate-tweak
02:58 PM JT-Shop: sudo apt install caja-open-terminal
02:58 PM JT-Shop: https://gnipsel.com/linuxcnc/software-fixes.html
02:58 PM Tom_dev: ok
02:59 PM Tom_dev: would that require a reboot?
02:59 PM JT-Shop: I think so
03:00 PM Tom_dev: let's find out
03:01 PM Tom_L: yup that did it. thanks
03:01 PM -!- #linuxcnc mode set to +v by ChanServ
03:01 PM linext: i'm trying to set up a lathe using a GRBL and Arduino UNO
03:02 PM linext: on a 3d printer, the endstops normally go to zero for each axis
03:02 PM linext: however, when I home the lathe on universal gcode sender, it triggers an ALARM in the status field
03:03 PM JT-Shop: what is GRBL?
03:03 PM Tom_dev: a dumbed down version of linuxcnc
03:03 PM linext: i don't know if it's an acronym for something
03:03 PM Tom_dev: gcode interpreter
03:04 PM Tom_dev: glue guns use it
03:04 PM JT-Shop: ah ok
03:04 PM linext: are the endstops on a lathe usually just used to detect an error state?
03:04 PM Tom_dev: G-Code Reference Block Library
03:05 PM JT-Shop: we have no clue about GRBL
03:05 PM JT-Shop: interesting but that has nothing to do with chickens or LinuxCNC
03:05 PM Tom_L: linext, ask in #grbl or #reprap
03:05 PM Tom_L: or C3 OR C8
03:05 PM JT-Shop: right
03:06 PM Tom_L: it has gotten better over the years
03:06 PM Tom_L: has most of the basic gcodes
03:06 PM Tom_L: not alot of canned cycles and none of the "COOL" stuff
03:07 PM Tom_L: she just took the Niece to the ER to get 'checked'
03:08 PM JT-Shop: hope that turns out ok
03:08 PM Tom_L: be kinda cool if it happened on my son's birthday
03:08 PM Tom_L: (today)
03:08 PM Tom_L: it will turn out one way or the other
03:09 PM Tom_L: no gettin around that
03:09 PM Tom_L: she's in denial but it's gonna be a C-section
03:10 PM roycroft: well that was fun - i was headed down to haul a load from the old shop when my pickup started pulling hard to the left and smoke came out of the front wheel
03:11 PM Tom_L: sounds like wheel bearing
03:11 PM roycroft: when i was able to pull over i found that the left side hub had pretty much disintegrated
03:11 PM JT-Shop: ouch
03:11 PM roycroft: maybe it's just a bearing, but i think it's worse
03:11 PM roycroft: fortunately i was able to find a place to pull over right past where it happened - there is no shoulder on the highway, and there is a lot of heavy, fast traffic
03:12 PM Tom_L: get in line at jt's fixit shop
03:12 PM JT-Shop: lol
03:12 PM roycroft: but i found a spot where i could park about 6 inches of the fog line
03:12 PM Unterhaus_ is now known as Unterhausen
03:12 PM roycroft: and when i called aaa i went outside the truck and stood quite a distance from i tuntil the tow truck arrived
03:12 PM _unreal_: wow I have a 112 hours run time on the new cnc machine already
03:13 PM Unterhausen: I got a ride from Virginia to Florida in a van with a bad front bearing. Driving that thing was fun, you had to predict where you wanted to steer 15 seconds into the future
03:13 PM roycroft: which did not take too long, since they made it a priority call, given that i was on a busy highway
03:13 PM _unreal_: glad I put the operation hour counter on the controller box
03:13 PM roycroft: anyway, it's home now, and it's parked where i can work on it
03:13 PM _unreal_: Unterhausen, ? FUN FUN
03:13 PM roycroft: i'm not going to deal with it at all today - i'm tired of the pickup right now, and it is raining
03:13 PM roycroft: it is not supposed to rain tomorrow
03:14 PM _unreal_: t4nk_fn, you live?
03:14 PM Tom_L: 4x4 or 2wd?
03:14 PM * roycroft thinks he should head down in the veloster and grab an ez-up from the old shop just in case it does rain
03:14 PM Unterhausen: the guy ended up replacing the bearing in a rest area in Florida. Somehow there was a repair shop at the rest areay
03:14 PM roycroft: 4x4 with abs
03:14 PM * _unreal_ bets its 2 wheel PEEL
03:14 PM roycroft: so it might not be fun to fix
03:14 PM roycroft: nor cheap
03:14 PM Unterhausen: He was moving, and had an acetylene torch in the van
03:14 PM JT-Shop: a young guy at a winery we like to go to first time I met him he was rebuilding the front hub of 4w drive and I was impressed with what he was doing with the tools he had
03:15 PM JT-Shop: so I gifted him my extra set of tools
03:15 PM Tom_L: cv joints don't generally go that quick unless the boot has been torn a long time
03:16 PM _unreal_: Tom_L, so I have a few project job offers right now. so I'm racing to get this wet jig done for the new cnc machine
03:16 PM _unreal_: they want me to do small 4x6" stainles 316 data/info sights for a boat
03:16 PM _unreal_: signs
03:16 PM _unreal_: sights=signs
03:17 PM _unreal_: I did a test and my machine did handle it with a 3/64th cobalt endmill
03:17 PM _unreal_: dry
03:17 PM _unreal_: clearly MUST be run in a flood do to having a high speed spindle
03:17 PM _unreal_: the slowest I can run that spindle really is like 8krpm
03:17 PM Tom_L: keep feed pressure on or it'll work harden
03:18 PM _unreal_: Tom_L, I'm very green to steel miling
03:18 PM Tom_L: ss is not normal steel
03:18 PM roycroft: steel and ss machine completely differently
03:18 PM roycroft: ss work hardens if you stare at it too hard
03:18 PM _unreal_: plus its a new machine so I dont have much for tooling different types of material on it yet history
03:19 PM roycroft: slow speed and very aggressive feed is what you need for ss
03:19 PM _unreal_: ya it was VERY clear I have to have FLOOD milling
03:19 PM roycroft: 8krpm is too fast ss with any cutter you can see without a microscope
03:19 PM _unreal_: my machine can do 450mm/min max travel rate
03:20 PM _unreal_: roycroft, not according to the details I was given. I need more RPM then what I was giving it.
03:20 PM Tom_L: i _think_ AITiN coating for carbide is what you want
03:20 PM _unreal_: Tom_L, never messed with it. again I'm new to SS
03:20 PM Tom_L: https://www.lakeshorecarbide.com/45and60degreehelixendmills.aspx
03:21 PM Tom_L: don't get cutters off amazon or ebay :)
03:21 PM _unreal_: Tom_L, what they want me to do reqires endmills in the at or SUB 1/16th " range for SS
03:21 PM NetPipe: and thennnnnn......
03:22 PM Tom_L: A common choice for machining stainless steel, AlTiN (Aluminum Titanium Nitride) is known for its high hardness and lubricity. It can withstand temperatures up to 1,400 °F
03:22 PM _unreal_: wording milled into 1/8th this 316 ss plate, 2-3 thow max
03:22 PM _unreal_: Tom_L, wrote it down
03:22 PM _unreal_: wrote
03:23 PM Tom_L: with a bit higher helix than normal but may not matter if you're just making surface cuts
03:23 PM Tom_L: 4 flute
03:24 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/cutters/carbide_6flute1.jpg
03:24 PM Tom_L: or 6
03:24 PM Tom_L: i doubt you could find one of those that small
03:25 PM Tom_L: ^^ was for Ti
03:25 PM _unreal_: ya I'm rather sure 2 flute will be what I find the most
03:25 PM Tom_L: ZRN coating for aluminum
03:26 PM Tom_L: Zirconium Nitride
03:26 PM _unreal_: I recently purchased 6 dbl ended bits, 3 3/64, 3/332, 3 1/16th 3 1/8th something like that
03:26 PM _unreal_: 6 bits $32 with %70 discount, the guy wanted to get rid of them
03:27 PM _unreal_: all cobalt
03:27 PM _unreal_: good deal or not I dont know but the guy is loaded with them
03:28 PM Tom_L: good for him.. he's gettin rid of em
03:28 PM Tom_L: may be a bit better than HSS
03:30 PM Tom_L: _unreal_, https://www.lakeshorecarbide.com/squarecornerengravingendmills.aspx
03:31 PM _unreal_: what would you suggest for a max feed rate for doing SS with a bit in that size range?
03:31 PM _unreal_: in MM
03:31 PM Tom_L: When machining stainless steel, a typical chip load ranges from 0.0005 inches to 0.006 inches depending on the cutter diameter
03:31 PM _unreal_: ooo nice tiny
03:32 PM rdtsc: recently drilled some 18ga ss plate where I punched one just a little too hard with a center... and went through five cobalt bits
03:32 PM Tom_L: i'd shoot for around .001" chip load
03:32 PM _unreal_: :S
03:32 PM Tom_L: so calculate your rpm, flutes and go from there
03:33 PM Tom_L: maybe a bit less on that tiny cutter
03:33 PM _unreal_: ya I kind of did that opening the holes. I installed the latest vesrion of ESTLcam and didnt relize one of the chnages adjusted an input variable
03:33 PM _unreal_: crashed a 1/8th single flute bit and broke it trying to mill the root size holes for all of the 1/4-20 thread holes in the plate I installed
03:33 PM Tom_L: closer to .0005" chip load on that tiny cutter
03:34 PM _unreal_: that was fun. I had to say F it and force puch it out with a drillbit in my drill press
03:34 PM _unreal_: saved the hole but ya like 3 drill bits later
03:34 PM _unreal_: k
03:34 PM Tom_L: .0125mm?
03:35 PM Tom_L: .0127
03:35 PM _unreal_: relating to?
03:35 PM Tom_L: per tooth chip load
03:35 PM _unreal_: OH
03:35 PM _unreal_: thought you were asking a question regarding what I had stated with the ? mark
03:35 PM _unreal_: heh
03:35 PM _unreal_: k
03:35 PM _unreal_: ya I do more or less everything in MIL;
03:36 PM _unreal_: inch runs out of accuracy when you get into small ranges unless you go micro multi digit decimals. and most milling hardware doesnt support it i've found.
03:36 PM _unreal_: mill's on the other hand no issue
03:37 PM rdtsc: if the SS grain structure work-hardens, only thing that may help is to heat that spot red-hot and let it cool slowly. gonna try that next time (not a decorative hole)
03:38 PM _unreal_: I just cleaned my cyclone drum. found my air leak, the caulking reacted to the pain that is on the drum so it make all kinds of bubbling. I was wondering why I had such a hard time maintaining a good sealed drum
03:38 PM roycroft: the only practical thing to do when machining ss is to not work harden it
03:38 PM roycroft: trying to temper it never works out well
03:38 PM _unreal_: rdtsc, I'm going to be flood cooling everthing I do so I dont think work hardening will be an issuse
03:39 PM rdtsc: hope not :) could also depend on the type of ss
03:39 PM _unreal_: FEEDS/SPEEDS on the other hand are a more aggressive issue
03:39 PM _unreal_: could
03:39 PM _unreal_: it will be thin
03:39 PM roycroft: 316 is one of the most difficult grades of ss to machine
03:40 PM _unreal_: My next 2 major steps are to go down town get a SINGLE freaking machine screw to replace one that I messed up. and get some hose. then I can more or less finish the wet jig box
03:41 PM _unreal_: roycroft, I'm hoping I conquer it.
03:41 PM _unreal_: $400 project for 2 plates
03:41 PM _unreal_: and if I knock this one out of the park. that company is going to flood me with work
03:41 PM _unreal_: at home work
03:42 PM _unreal_: well I'll bbiab got to run to the store
03:42 PM _unreal_: get that bit and a bit of hose
03:42 PM _unreal_: :)
03:42 PM roycroft: looks like <$15 if i just need a bearing, and about $200 if i need the bearing assembly
03:42 PM roycroft: for parts
03:42 PM rdtsc: typical... good luck roycroft
03:43 PM roycroft: if i take it in for repair i'm sure it will be $500 or more
03:43 PM Tom_L: roycroft, still better than a rearend worth of traffic up yours
03:43 PM roycroft: so as much as i hate working on vehicles i'll probably give this a go myself
03:44 PM roycroft: i especially hate working on vehicles in my driveway, which is exactly what i'll be doing here
03:44 PM roycroft: but if it's just a bearing or bearing assembly it should not be too difficult
03:44 PM roycroft: unless something else got damaged when it happened
03:44 PM roycroft: i drove it less than a mile after the failure
03:45 PM roycroft: very slowly
03:45 PM Tom_L: hot enough to smoke the grease
03:45 PM rdtsc: only way to know is to tear into it
03:45 PM * roycroft decides to work on another project today and pull the wheel tomorrow
03:46 PM rdtsc: recently filled in an uneeded slide valve slot, some unknown grade ss... used ER309L rod and a ss washer to help fill the gap... worked, but was a challenge indeed... ss is funny stuff
03:47 PM rdtsc: speaking of welding, wonder how skunkworks is doing on his oil-tank
03:49 PM roycroft: i'm just glad my air compressor is online again
03:50 PM roycroft: i'd hate to tackle that job without an air impact driver
03:50 PM rdtsc: picked up a Worx impact driver from the local Menards... pleasantly surprised, worked great
03:52 PM rdtsc: https://www.worx.com/nitro-20v-power-share-1-2-cordless-impact-wrench-with-brushless-motor-tool-only.html
03:53 PM Unterhausen: I only ever need to work on cars when it's really cold outside. I suppose it makes sense
03:53 PM roycroft: i don't use one often enough these days to justify buying a cordless one
03:54 PM * roycroft is not interested in investing any money at all in automotive tools
03:54 PM roycroft: i have plenty
03:54 PM roycroft: and if i don't have it, i'll borrow it, rent it, or get someone else to do the work
03:55 PM rdtsc: the latter is my preferred method
03:56 PM rdtsc: just because we have tools, does not mean we want to be underneath a 2-ton car working on it in freezing temperatures
03:56 PM roycroft: exactly
03:57 PM roycroft: car wrenching usually inovlves cold, messes, and contortions
03:58 PM roycroft: and toss in some rain for good measure
03:58 PM rdtsc: and an assured injury of some sort
03:58 PM * roycroft is not interested in any of those things
03:58 PM * roycroft wanders off to do the other projects
03:59 PM rdtsc: time to wrap a few gifts
03:59 PM JT-Shop: you wrap coal?
04:00 PM rdtsc: bah humbug! coal is too nice for these scurvy dogs!
04:00 PM rdtsc: they get brick bats :)
04:01 PM JT-Shop: lol
04:22 PM Tom_L: https://www.youtube.com/shorts/8IZwiNLGIDU?feature=share
04:24 PM JT-Shop: lock miter joints on a shaper in under a minute not going to happen
04:31 PM skunkworks: I found dad has a bunch of quarts ford blue..
04:31 PM skunkworks: lol
04:32 PM skunkworks: so. https://photos.app.goo.gl/zCJREEdRAdkdj9hq7
04:32 PM skunkworks: don't look too closly at the paint job and the welding...
04:32 PM skunkworks: the paint was brushed on - and it was too thick.. Should have thinned it
04:32 PM * JT-Shop zooms in
04:32 PM skunkworks: NooooooooO!
04:33 PM skunkworks: I ran out of co2.. so it is what it is.. (honestly you could probably pick the tractor with it.
04:34 PM JT-Shop: you should see the paint job on the C3 frame that I did
04:34 PM skunkworks: heh
04:34 PM JT-Shop: mainly cleaned and painted that area to stop the rust
04:35 PM JT-Shop: it's amazing how much splatter the welder left as well as bits of wire from the mig welder
04:38 PM skunkworks: yep
04:39 PM skunkworks: I should get a decent small welder that will do tig..
04:39 PM JT-Shop: I guess 42 years ago mig welders were not as good as today
04:39 PM skunkworks: This is a small miller that never worked very well. The 400amp welled is in a different building that doesn't have 3 phase
04:40 PM skunkworks: still not organized yet
04:40 PM JT-Shop: the welder I'm talking about is the person that welded the frame of the 82 C3
04:44 PM JT-Shop: hmm I need to go "paint it black" before the time runs out
04:44 PM skunkworks: lol
04:48 PM skunkworks: I painted mine black - before blue
05:03 PM * JT-C3_Shop shuts down the shop
05:05 PM xxcoder: zoom. enhance. zoom that spot. enhance.
05:06 PM xxcoder: gonna love csi magic
05:06 PM xxcoder: I think? might be wrong show. basically they zoomed into guy wearing mirrored glasses, for reflection to car plate
05:06 PM xxcoder: it probably was orginally 6 pixels
06:03 PM rdtsc: science "fiction"
06:04 PM rdtsc: rooted in science, but complete fiction
06:06 PM rdtsc is now known as rdtsc_away
07:27 PM xxcoder: amazing blondy ax video today (blondihack)
08:22 PM roycroft: matt cremona's video today is also excellent (i haven't watched blondihacks yet - i'll watch it this evening)
08:22 PM roycroft: he had some slabs that were not stickered properly and had twisted about 3 inches
08:23 PM roycroft: he built a steam box and flattened them by steaming them then stickering them with some dunnage and a forklift sitting on top of the slabs
08:36 PM CloudEvil: :)
08:38 PM xxcoder: fun
09:50 PM _unreal_: It is officially finished. technically I need to lift the aluminum plate and caulk the 2 center pads but I'm not worried about it currently
09:50 PM _unreal_: tomorrow I'm going to do my first stone test. OR stainless
09:50 PM _unreal_: not sure which
09:56 PM * roycroft got an ez-up from the old shop this afternoon, and will investigate the wheel bearing issue in the morning
09:56 PM Tom_L: _unreal_, https://www.amazon.com/FACHLICH-Diamond-Porcelain-Existing-Enlarging/dp/B0865LCKQF
09:57 PM _unreal_: nifty though for a 4" grinder
09:57 PM Tom_L: more about the abrasive
09:57 PM _unreal_: My spindle can only take upto 7mm
