12:01 AM Wolf__: malcom2073: pong
12:04 AM CaptHindsight: reminded me of this https://youtu.be/rCyr1ugzxXM?t=1m38s
12:04 AM CaptHindsight: Monty Python Twit Race Sketch
12:08 AM IchGucksLive: hi
12:12 AM * evilroot goes back to watching post apocalyptic anime
12:16 AM homicidlbrainiac: evilroot, what's the best post-apoco type anime right now?
12:18 AM CaptHindsight: binging on The Crown SE2
12:19 AM evilroot: Well the new Eva has awesome movies
12:19 AM CaptHindsight: almost makes you feel sad for the monarchs
12:20 AM evilroot: Right now Shoujo Shuumatsu Ryokou
12:20 AM homicidlbrainiac: There's a new EVA?
12:20 AM evilroot: Yeah . . .
12:20 AM homicidlbrainiac: I miss having a life
12:22 AM evilroot: https://www.youtube.com/watch?v=1__8I6tjxjM
12:22 AM homicidlbrainiac: OK looking it up, so it looks like the one I missed was Rebuild of Eva
12:22 AM homicidlbrainiac: ooh and that
12:24 AM evilroot: Rebuild is really old
12:25 AM evilroot: 1.x, 2.x, 3.x are quite new
12:25 AM evilroot: And Studio Gainax actually had a budget
12:26 AM homicidlbrainiac: Wow I totally have to watch all these
12:26 AM homicidlbrainiac: thanks!
12:26 AM evilroot: They ran out of money at the end of the original Eva series
12:27 AM homicidlbrainiac: Looking at the trailer, man it's even more dark and depressing than before
12:27 AM homicidlbrainiac: which is totally awesome
12:27 AM evilroot: Heh
12:27 AM homicidlbrainiac: You ever watch the movie threads done by BBC, circa 1984?
12:27 AM evilroot: Shinjii isn't as much of a pussy either
12:27 AM evilroot: Which is nice
12:28 AM * evilroot is a huge anime geek and speaks Japanese
12:30 AM homicidlbrainiac: Shinjii had daddy issues
12:30 AM evilroot: More like mommy issues
12:31 AM homicidlbrainiac: Wait, isn't he riding around with his mommy all the time?
12:32 AM homicidlbrainiac: Gotta run in a sec and shut down everything for the night
12:32 AM evilroot: And hanging out with her AKA Rei
12:32 AM evilroot: You saw Gunbuster right?
12:32 AM homicidlbrainiac: nope not yet
12:32 AM evilroot: That's the ultimate classic
12:32 AM homicidlbrainiac: But it's on the list
12:32 AM evilroot: Dude, it came before Eva
12:32 AM evilroot: And was even more epic
12:32 AM evilroot: They ran out of money so the last ep was in black and white
12:33 AM homicidlbrainiac: I remember watching southern cross when I was a little one.
12:34 AM homicidlbrainiac: But that's about as oldschool as I get
12:34 AM homicidlbrainiac: Thanks for all the viewing suggestions
12:34 AM homicidlbrainiac: I got it on my list
12:35 AM evilroot: Gunbuster is only 6 episodes, heh
12:35 AM homicidlbrainiac: but yeah as you can tell, I love the apocalypse genre
12:36 AM homicidlbrainiac: Gotta get some sleep, haven't done so in a long long time
12:36 AM homicidlbrainiac: I'll be back
12:36 AM homicidlbrainiac: Pretty cool talking to you (and everyone else here)
01:38 AM gloops: c axis could be a challenge, rotary spindle
01:59 AM gloops: how would you code so that if say x and y were cutting an arc, half a circle say, the C (rotary spindle) kept ar a radius to the circle
02:01 AM Deejay is now known as Guest34091
02:01 AM Guest34091: moin
02:03 AM Guest34091: whut
02:03 AM Guest34091 is now known as Deejay_
02:04 AM Deejay_ is now known as Deejay
02:22 AM gloops: the centre of the arc would probably be a better reference point as it is constant
02:36 AM archivist: gloops, you mean an arc like http://www.collection.archivist.info/archive/DJCPD/PD/2008/2008_10_07_cnc_Racing_gears/p1010073.jpg
02:37 AM archivist: x y stay still while the rotary moves and the spindle cuts
02:38 AM archivist: same for http://www.collection.archivist.info/archive/DJCPD/PD/2004/2004_10_08_cycle/P1010013.JPG
02:39 AM archivist: except the second was manual not cnc and has extra xy under the rotary
02:41 AM archivist: made on an old boley jig mill
02:42 AM archivist: http://www.lathes.co.uk/boley%20miller/img0.gif
02:47 AM archivist: miss0r, http://www.collection.archivist.info/archive/manuals/IM74_NEC_multisync/ has the small switches as well
02:48 AM miss0r: I have read your manual already, thanks. It actualy helped me understand i've been an idiot :)
02:49 AM XXCoder: heys
02:56 AM IchGucksLive: going garden nice in germany
03:03 AM gloops: the steel in the garage is lovely and warm to handle...
03:04 AM XXCoder: radioactive? recently cut? recently baked?
03:04 AM * gloops weeps a bit while the feeling comes back to his fingers
03:04 AM gloops: only -1C
03:04 AM archivist: too warm for fingers to stick to it
03:04 AM gloops: yes no excuses for stopping
03:07 AM gloops: archivist the rotary direction im talking about is like this - https://www.youtube.com/watch?v=A-vzZzfmH4Q
03:08 AM gloops: the spindle is like plotting the radius of the arc
03:09 AM archivist: cant see yt on this box
03:09 AM gloops: simultaneously
03:10 AM archivist: like the bottom image http://www.collection.archivist.info/archive/Mal/BK/BK410/plate28s.jpg
03:12 AM gloops: https://uk.images.search.yahoo.com/yhs/search;_ylt=AwrIRhOyqCtaZhoA6pt3Bwx.?p=cnc+horizontal+router+spindle&fr=yhs-ddc-linuxmint&fr2=piv-web&hspart=ddc&hsimp=yhs-linuxmint&type=__alt__ddc_linuxmint_com#id=44&iurl=https%3A%2F%2Fs-media-cache-ak0.pinimg.com%2F736x%2F3d%2F6b%2Fcd%2F3d6bcd257ce6e62dd9d5a7fbbcf123f1.jpg&action=click
03:12 AM gloops: spindle that way, rotates on the hub above
03:13 AM gloops: x and y cutting an arc - spindle moves to keep the cutter on the radius of that arc
03:13 AM gloops: basically synchronising the radius of the rotary with the arc being cut
03:14 AM gloops: https://i.pinimg.com/736x/3d/6b/cd/3d6bcd257ce6e62dd9d5a7fbbcf123f1.jpg
03:15 AM archivist: gloops, with the right kins in linuxcnc
03:16 AM gloops: mechanically possible, but the g code would require some maths
03:16 AM archivist: the maths can be in the kins, you dont need to code it
03:17 AM gloops: so it would automatically plot on the radius of any arcs cut by x,y
03:18 AM archivist: cradek has a nice example of drilling around an arc
03:18 AM gloops: excellent, so that would not be a massive obstacle
03:20 AM gloops: that actually makes 4 axis feasible, maybe 5, i was pretty daunted watching some vids thinking what coding would be required
03:22 AM archivist: I cant see the vid but text https://www.youtube.com/watch?v=aF7C8d4d0nc
03:22 AM gloops: lol, ive got ideas for machines that would keep me busy till i die, learning all this is like doing a phd
03:22 AM archivist: seen it some years ago
03:24 AM gloops: that is pretty good
03:24 AM archivist: https://www.youtube.com/watch?v=fWKYQUj5AOs
03:24 AM archivist: effin google stopping the format I could see
03:25 AM gloops: yes that is exactly what im talking about
03:26 AM gloops: so you define the centre point, or maybe a formula for determining the centre point, and the rotary will automatically track that
03:26 AM archivist: so its built in if you want it
03:26 AM gloops: as opposed to coding every rotary change of angle
03:27 AM archivist: there is a dutch/belgian video which shows 5 axis too
03:28 AM gloops: we have got to get this going haha
03:29 AM archivist: one can do it in gcode if you want too
03:31 AM gloops: for more simple shapes the g code would be doable
03:31 AM archivist: see my escape wheel tooth video
03:31 AM gloops: but for some complex scuplture maybe, a built in formula would be ideal
03:32 AM archivist: https://www.youtube.com/watch?v=adT8Dr5JZ4c
03:33 AM archivist: done in gcode
03:33 AM gloops: that is pretty good, you ought to be making some money with this
03:34 AM gloops: well its ok me dreaming about other machines, i better get this one finished, bbl
03:34 AM archivist: 16 views 0 orders in 9 years
03:35 AM archivist: 11k views
03:35 AM gloops: wrong place, set it up on ebay - custom gears cut
04:20 AM IchGucksLive: hi i need a search name for a toolchanger that has all tools in line to one workplane side
04:20 AM IchGucksLive: someone knows if it is already done in a config
04:55 AM jthornton: morning
04:57 AM jthornton: rack toolchanger
05:00 AM IchGucksLive: thangs
05:00 AM IchGucksLive: jthornton: do you got beside the ones brigeport from thomas any configs
05:00 AM IchGucksLive: as from 2.8 it might be easyer to go by G53 moves
05:01 AM jthornton: I wrote my configs for all my machines except the lathe and Robh sent me his for that
05:06 AM IchGucksLive: as we all do
05:06 AM IchGucksLive: thanks
05:10 AM IchGucksLive: jthornton: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?RackToolChanger
05:10 AM IchGucksLive: very old
05:13 AM jthornton: rack tool change site:linuxcnc.org gets many recent hits
05:14 AM IchGucksLive: Chris_Morley: online ?
05:16 AM jthornton: might be a bit early for him 3:15AM at his house
05:16 AM jelly-home is now known as jelly
05:20 AM IchGucksLive: ;-)
05:20 AM IchGucksLive: off
05:25 AM gloops: perfectly square frame, welded 4 corner posts on with all due care and attention - tops 15mm out of square after cooling lol
05:26 AM archivist: tack weld first!
05:26 AM gloops: i did
05:26 AM archivist: blowlamp get it red hot and bend
05:26 AM gloops: its ok anyway i planned for it, didnt quite expect 15mm though
05:27 AM gloops: rails bolted to posts in slots
05:28 AM gloops: also erred on the posts leaning out, hopefully will pull back in with bolts
05:28 AM jthornton: when I weld stuff that might pull like a T, I don't get it as hot as normal
05:28 AM jthornton: weld a tiny bit and walk away till cool
05:29 AM gloops: i had 3 tacks on each box section - squared with 2 squares at that point
05:29 AM jthornton: got a photo of it?
05:30 AM gloops: no not taken any - they sight in ok its not like they look out of square, but accross the diagonals 1500x1250mm - 15 mm out
05:31 AM gloops: 1500x1250 frame
05:37 AM gloops: can lay bricks closer lol
05:40 AM gloops: think ill have 10 minutes finding the offending bits and do some grinding
05:42 AM jthornton: 26F this morning a heat wave
05:57 AM malcom2073: Supposed to snow here sometime today
05:59 AM jthornton: we have clear skies for the next week
06:07 AM malcom2073: Nice
06:40 AM Tom_L: 33°F
06:40 AM gloops: about -1 C here
06:40 AM Tom_L: warming trend
06:41 AM gloops: maybe 1C
06:41 AM gloops: about the same
06:41 AM Tom_L: started on my axis mounting plates last night http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Y_Axis_Plate3.jpg
06:42 AM gloops: that looks ok
06:42 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Y_Axis_Plate2.jpg
06:42 AM Tom_L: front side
06:43 AM gloops: using a template for the holes Tom?
06:43 AM jthornton: what are you using to machine the holes?
06:43 AM gloops: i cant find one for my bearings
06:43 AM Tom_L: i located the holes with the sherline then drilled the counterbores on the drillpress
06:44 AM Tom_L: had to flip the part on the sherline and it still took all it's travel
06:44 AM jthornton: cool
06:44 AM Tom_L: coungerbore bit is alot easier
06:45 AM Tom_L: counter*
06:47 AM gloops: ive got all main framework done, needs some welding finishing but leaving it at this for now, couple of sbr rails to fit and some bolting to do, will have rolling gantry
06:48 AM gloops: i can see already this is going to be a handsome machine
06:48 AM jthornton: I can't see it from here
06:49 AM gloops: lol, ill post some pics before i get to the painting stage
06:49 AM gloops: few spanners and bits and bobs to put away in the garage...
06:50 AM archivist: no hiding the mess in the background!
06:51 AM gloops: nothing really to see at the moment nothing is mounted on bearings
06:52 AM Tom_L: jthornton, when you weld the short strips and let cool, about how long a strip would that be?
06:52 AM Tom_L: i'm gonna try to minimize the warping on this but i'm sure it will happen
06:53 AM jthornton: I weld about an inch, if the part is big like a flat sheet to a drum I will weld in about 8 places then let it cool... all depends on the joint
06:53 AM Tom_L: yeah, that's about what i figured
06:54 AM Tom_L: you don't really need a continuous bead on everything anyway do you?
06:55 AM archivist: tack then see where it needs to be pulled a bit and short weld on a more open gap
06:55 AM gloops: i couldnt clamp these posts i just welded, i left a gap, tacked one corner, check and put square again, tacked opposite corner, put square again, another tack - squared up
06:55 AM Tom_L: yeah, i figured i'd move around as needed
06:55 AM jthornton: only if it needs to be water tight or something like that
06:55 AM gloops: welded 1 inch welds on 3 sides - all over the place
06:55 AM Tom_L: i'll clamp it all down to my table
06:55 AM Tom_L: might help some
06:56 AM archivist: clamps are weak compared to shrinkage
06:56 AM jthornton: but they can help
06:56 AM gloops: clamps help but theyre nothing compared to those forces true archivist
06:57 AM archivist: weld in webs and cross braces
06:57 AM archivist: before/during
06:57 AM jthornton: and if you have an oven big enough you can normalize the part after welding and watch it move back to straight
06:57 AM Tom_L: has to be pretty hot
06:58 AM archivist: dull red should move
07:04 AM archivist: some mention hammering welds to stretch them
07:06 AM gloops: are you ever moving the weld though, or just bending the steel
07:06 AM gloops: dont suppose it matters
07:07 AM archivist: think how a blacksmith thins a bit and the metal gets longer
07:07 AM gloops: weld metal is harder than mild steel though, the steel will stretch first
07:10 AM gloops: thats why they all use those ally extrusions, dead flat, easy to connect, no welding
07:11 AM archivist: al has other problems, its not straight!
07:11 AM gloops: they claim it is
07:12 AM Tom_L: i claim to have been to the moon too
07:12 AM archivist: we had some extrusions made for us, the extruder told us about errors
07:13 AM archivist: it slumps just out of the die, the workers if good can get the conveyor set right to minimise
07:15 AM gloops: well i was going to scrape this steel, but the straightedge rubs the rust in pretty evenly
07:15 AM gloops: think ill go with it as it is and see how it goes
07:16 AM Tom_L: my attitude on this build is anything will be better than my sherline
07:17 AM gloops: you can always get it right, bit off here, couple of shims there
07:17 AM Tom_L: i'm going to _try_ to minimize that
07:20 AM gloops: one thing with wood, its mostly only got to be good enough to the eye, doesnt have to dial in to thous
07:20 AM gloops: anyway ill do a bit more
08:09 AM XXCoder: https://www.youtube.com/watch?v=tvqofcFaF30 pretty cool
08:16 AM anonnumberanon: Tom_L are you putting only z on your gantry and x and y on the table?
08:19 AM XXCoder: lol mini lathe is back on sale
08:19 AM XXCoder: $30
08:19 AM XXCoder: er 40
08:33 AM anonnumberanon: Any good computer motherborad dedicated to linuxcnc? I found an asus one that was nice and with parallel port plus it is supported but iirc it was $70. A bit seep.
08:35 AM archivist: I just test all my old spare pcs to find a usable one
08:41 AM anonnumberanon: Im running out of old pcs
08:41 AM anonnumberanon: :S
08:42 AM JT-Shop: anonnumberanon: http://paste.ubuntu.com/26146654/ a partial list of motherboards I'm using
08:45 AM anonnumberanon: All very pricey i see
08:47 AM archivist: I got a bunch of pcs of ebay from an internet cafe, also freecycle etc
08:47 AM gloops: car boot sale, giveaway prices, if they have them where you are
08:49 AM anonnumberanon: Yeah. Ill be fine. Better to install linuxcnc or install the debian linuxcnc image?
08:50 AM gloops: i used the bootable iso, easier for me
08:51 AM IchGucksLive: anonnumberanon: you are on Steppers or servos
08:52 AM IchGucksLive: gloo ;-)
08:52 AM anonnumberanon: Steppers
08:52 AM IchGucksLive: almost evers board can go 12000 steps per second evn on 100k latency
08:52 AM IchGucksLive: its a mess but it goes
08:53 AM IchGucksLive: the asusP5 serius is the best
08:53 AM IchGucksLive: came down to below 5k constant
08:54 AM IchGucksLive: anonnumberanon: thy to stay below 50USD for PC
08:54 AM IchGucksLive: get a coool ols ibm
08:54 AM IchGucksLive: OUW wiki is realy outdates as most is 10.04
08:55 AM anonnumberanon: I would like to wait on getting part until I'm in the middle of building the fram
08:55 AM IchGucksLive: oh you decided#
08:55 AM IchGucksLive: i did mount only 2 today
08:55 AM anonnumberanon: You sell them fast!
08:55 AM IchGucksLive: the Students forgot 8 holes to drill
08:56 AM IchGucksLive: no noone is sold in almost 10 years
08:56 AM IchGucksLive: its all "free"
08:57 AM IchGucksLive: oh grandchilden are in for snowslide
08:57 AM IchGucksLive: im off
08:59 AM anonnumberanon: This fits the bill quite nicely https://m.ebay.com/itm/Asus-P5E-VM-DO-Motherboard-Core-2-Quad-Q8400-2-66GHz-CPU-4GB-RAM-HSF-I-O-/302515614001?nav=SEARCH
09:03 AM gloops: found something else out
09:04 AM gloops: the black plasticy looking liner in sbr bearings, that looks like plastic but obviously must be metal as its a bearing - is actually plastic
09:04 AM gloops: and it breaks
09:06 AM ziper: can you have a device that grinds the ways it rides on
09:06 AM ziper: like a train that lays its own track
09:07 AM gloops: yes
09:18 AM gloops: https://www.youtube.com/watch?v=7NGEQFJdmo4
09:18 AM anonnumberanon: Nust noticed that z axis never moves much
09:19 AM anonnumberanon: *Just
09:29 AM merkatorix: If there is an parallel port aviable, so linuxcnc works. Would you see any reason to use Mach4? When it is about VisualC++ and GCC, often even GCC users like the VC-Debugger. When it is about Windows and Linux, Linux users have to admit the better driver support for consumer hardware. I am just planning the far future and am completely new to the topic. Is it file support and support for 3D probes and tool changers?
09:29 AM Loetmichel: anonnumberanon: you dont even need a quad
09:29 AM Loetmichel: my CNC6040 runs with a 2.8ghz core2duo mighty fine
09:30 AM Loetmichel: including webcam-encoding and remote desktop
09:30 AM merkatorix: I expect LinuxCNC to be far superior if I want batch scripts (to locate a PCB, probe it, mill it, drill it...) and maybe I could ultimately monitor the whole process using SSH and a webcam.
09:30 AM merkatorix: Loetmichel, are you the Loetmichel from Mikrocontroller and CncEcke?
09:30 AM Loetmichel: yes
09:30 AM merkatorix: As I already saw you doing PCB Milling and having good results, I was about to ask you about your mill.
09:31 AM merkatorix: But I thought you might be one of the users having professional tools :D Never expected a CNC6040, which is the better version of the cheapest cnc3040,isn't it?
09:31 AM Loetmichel: and i did that remote monitoring already: works fine ;) -> https://www.youtube.com/watch?v=9u_ChO1AKYY
09:31 AM merkatorix: Which one did you use for CNC-Milling?
09:32 AM Loetmichel: it is a bigger version of the cheap 3040
09:32 AM merkatorix: pcb milling, i meant.
09:32 AM Loetmichel: double the x size to be exact
09:33 AM Loetmichel: it does PCB milling mighty fine, too: https://www.youtube.com/watch?v=9u_ChO1AKYY
09:41 AM anonnumberanon: Nice data point Loetmichel thanks
09:43 AM Loetmichel: anonnumberanon: my pleasure
09:45 AM anonnumberanon: Webcam-encoding does what? Makes sure the mill stays longer if the material has a hatd spot in it?
09:46 AM anonnumberanon: Hard spot*
09:53 AM SpeedEvil: I think he just means for remote viewing
09:54 AM gloops: well, despite my initial horror with the sbr bearings, now ive actually got some rolling they are quite adequate i think
09:55 AM gloops: very smooth, no play
10:02 AM anonnumberanon: Oh :)
10:03 AM anonnumberanon: A camera would need a shield to protect it from shavings and lubricant
10:03 AM anonnumberanon: Been thinking about that.
10:03 AM gloops: yes, you can leave your machine cutting and go to the beach and watch it from there
10:04 AM anonnumberanon: Maybe high pressure air making a shield in front of it.
10:04 AM gloops: if you have a cam on the garden you can watch your house burning down as well
10:04 AM anonnumberanon: Lmao
10:05 AM archivist: done use machines remotely or wander off, houses do get burnt down
10:05 AM archivist: dont
10:06 AM archivist: we had a user in here walk off from his laser
10:07 AM gloops: what happened?
10:08 AM archivist: was cutting rubber, caught fire house well alight
10:08 AM Contract_Pilot: morning
10:09 AM gloops: left a laser cutting rubber lol
10:09 AM gloops: i had z plunge straight into wood - smoke but not fire, was in garage
10:10 AM archivist: al least over here brick built
10:10 AM gloops: yeah, tbh not much to burn really, well there wasnt till i boarded it out
11:15 AM malcom2073: Wolf__: Sorry I missed you, was wondering if you or anyone you knew wanted one of these: https://www.millerwelds.com/accessories/trailers/trailer-4-west-m00400 , looking to trade a decent sized generator
11:25 AM Loetmichel: anonnumberanon: have you seen the video?
11:25 AM Loetmichel: i use my CNC at the company often from the office because its way quiteer that way
11:26 AM Loetmichel: and you dont have to worry about swarf/water if you use an "endoscope" type webcam
11:26 AM Loetmichel: they have a glass window in front of the lens, lighting built in AND are watertight
11:26 AM Loetmichel: quieter
11:28 AM SpeedEvil: and are often very very cheap and easy and small to replace
11:28 AM Loetmichel: yeah, that too
11:29 AM SpeedEvil: stock part, rather than something to be babied
11:30 AM Loetmichel: that said: my office is just two doors across from the workshop, so i can be in there in less than 5 seconds if something goes cathastrophically wrong
11:30 AM Loetmichel: wouldnt recommend my setup if you have half an hour drive to the shop ;)
11:31 AM IchGucksLive: hi
11:32 AM SpeedEvil: Loetmichel: I do wonder how much of normal machine shoppy stuff you could do with a VR rig and a very, very expensive stock industrial arm
11:33 AM Loetmichel: make it two arms in the right distance and a stereo cam and i bet a LOT
11:33 AM SpeedEvil: indeed
11:33 AM SpeedEvil: Especially if willing to go slow
11:33 AM Loetmichel: no need to go slow
11:34 AM Loetmichel: most of the kuka robot arms are faster AND stronger than a human arm
11:34 AM SpeedEvil: Loetmichel: yes, but the interface to them isn't
11:34 AM Loetmichel: just low latency video encoding and good hand digitizers
11:34 AM SpeedEvil: Loetmichel: delays and ... in the interface mean that simple AR is going to be rather problematic for simple stuff
11:35 AM Loetmichel: i think i can make something like linuxCNC act fast enough that you dont feel any delay between hand movement and robot movement
11:35 AM Loetmichel: the video stream back is more of a problem though
11:36 AM SpeedEvil: Perhaps, yes
11:36 AM Loetmichel: and the missing sense of touch
11:36 AM SpeedEvil: The subset of 'stuff you can do in thick gloves' is still pretty useful thoguh
11:37 AM Loetmichel: and it doesent get you all sweaty if you have to file/saw something by "hand"
11:38 AM Loetmichel: i would want to see a 10 times oversized bot though with that tech, a big chainsaw and a claw as hands and then go into the woods and make logs
11:38 AM Loetmichel: THAT would be a nice application
11:38 AM Loetmichel: especially if the video feed is augumentet with some measurement "lasers" and stuff
11:39 AM SpeedEvil: The other side is almost more interesting
11:40 AM SpeedEvil: 100* down
11:40 AM Loetmichel: or for a brick layer that now can handle big stones without a crane
11:40 AM Loetmichel: SpeedEvil: and do clockwork stuff?
11:40 AM SpeedEvil: yes
12:32 PM dave__ is now known as gloops
12:54 PM anonnumberanon: Bad news the recycled pc i thought i could use has no supply, no ram, no cpu, no parallel port, a few bent pins on cpu socket and 2 cpu sockets which i dont know is supported..
12:55 PM gloops: nah dont bother with that, loads around
01:12 PM CaptHindsight: Loetmichel: we bypass the robot controllers if we need real time, <100ms feel, like a light switch
01:13 PM CaptHindsight: same for real time synchronized positioning to inkjet or laser
01:13 PM CaptHindsight: the robot controllers are only made to sync fast enough for things like welding
01:14 PM CaptHindsight: they will tell you where the arm is every 10-100mS based on the controller
01:16 PM CaptHindsight: LCNC directly controlling the arm motors is fast enough for what you describe
01:25 PM andypugh: I need an actuator to remotely operate the start button in a car.
01:25 PM andypugh: I am thinking that a “Useless box” might be a good source.
01:25 PM malcom2073: I read that, and though wtf? Then I realized it was you, and figured you might have a decent reason for doing something so silly? :P
01:31 PM andypugh: I do. I lost a test yesterday that I had planned (badly) for months because it turned out my medical for the altitude chamber had expired. We need two people in the room with CPR training any time we are testing in there because it takes a minimum of 4 minutes to open the doors.
01:33 PM malcom2073: Makes sense
02:02 PM Contract_Pilot: Cool.... look like my pathpilot 2.0 drive will be here monday...
02:16 PM anonnumberanon: Gloops yeah it would just have been really neat :)
02:18 PM gloops: still, i suppose living in england we take it for granted theres always loads of everything around, i know thats not the case in places like parts of the usa, canada and so on
02:22 PM Loetmichel: gloops: when i look around here in my hobby room... i see at least 15 operational PCs, and at least 11 working notebooks in this house...
02:22 PM Loetmichel: ... i am kind of a hoarder. does it show? ;)
02:23 PM gloops: ive got 5 old PCs, like desktops, dont think it cost ÂŁ40 for the lot
02:25 PM Loetmichel: yeah, recently i bought a bunch of not THAT old PCs for the company at a leasing refurbisher.
02:25 PM Loetmichel: DIRT cheap
02:25 PM gloops: last one i got was ÂŁ15 on the car boot sale, woman asked me if i wanted the monitor for another ÂŁ5, no dont want the monitor, well you can have it for free i want rid, ok then, take the keyboard and the other stuff as well
02:25 PM Loetmichel: like $80 for an I3 with 4gig ram and a 250 gig HDD.
02:26 PM gloops: cant go wrong really Loet
02:44 PM CaptHindsight: I left a pallet of old PC's out since they want ~$40/pc to recycle them around here
02:45 PM CaptHindsight: it's illegal to toss them in the trash
02:46 PM gloops: they are junk really yes, unless you want an old pc for some reason
02:47 PM Loetmichel: CaptHindsight: thankfully we have "wertstoffhof" here in germany in every city which are city-paid recycling grounds for all kinds of materials. from furniture over green cuts to electronics and steel: they take it and dispose of it correctly. IF your passport shows that you live in the city
02:47 PM Loetmichel: free of charge
02:47 PM CaptHindsight: here it's a business
02:48 PM CaptHindsight: you open a recycle plant, where you really just pile it up for years then go bankrupt and walk away
02:48 PM Loetmichel: with PCs that would be unwise
02:48 PM CaptHindsight: or sell it to an offshore buyer
02:48 PM Loetmichel: alone the gold in the contacts are about $ 50 in each PC
02:49 PM Loetmichel: so recycling it properly would gain you a pretty nice pile of cash
02:49 PM CaptHindsight: too much work
02:49 PM gregcnc: on a german schematic can I assume 68E/800W is 68 ohms?
02:49 PM Loetmichel: 800W?
02:50 PM gregcnc: 800W is clear
02:50 PM Loetmichel: whats that? a resistor?
02:50 PM gregcnc: yes
02:50 PM Loetmichel: E isnt really usual for ohms
02:50 PM Loetmichel: are you sure its an E?
02:50 PM gregcnc: spindle drive brake resistor
02:51 PM gregcnc: I have to check it. I suppose it's either going to give a reading or be open
02:51 PM CaptHindsight: might be 6.8ohms or .68
02:51 PM Loetmichel: CaptHindsight: nope
02:52 PM CaptHindsight: run the numbers.... whats the drive voltage?
02:52 PM Loetmichel: doesent work out at neither 325V nor ~700V DC bus
02:52 PM gregcnc: 400V machine
02:53 PM CaptHindsight: is the resistor currently open?
02:54 PM gregcnc: havent checked yet. The resistor itself is buried in the machine and I can't see the nameplate.
02:54 PM gregcnc: Spindle is not stopping like it should so tapping is a nogo
02:55 PM CaptHindsight: Ohms = (DC bus volts)²/(Peak power)
02:55 PM Loetmichel: gregcnc: could that 68E be a simple connector designation=?
02:56 PM Loetmichel: my math says it should have about 300 ohms to dissipate 800W at ~600V dc
02:56 PM gregcnc: connectors are listed separately
02:56 PM gregcnc: I'm off to measure
02:56 PM CaptHindsight: probably 68 ohms, the E is for effort
02:57 PM Loetmichel: trolling again?
02:58 PM CaptHindsight: jesting
02:58 PM CaptHindsight: part of a concept referred to as "humor"
03:00 PM Loetmichel: i am a german, remember? No humor ;)
03:00 PM CaptHindsight: it's never too late
03:03 PM andypugh: Loetmichel: Not your day with the German Sense of Humour then?
03:04 PM Loetmichel: andypugh: all you brits and americans tell me that germans have no sense of humor. So i try to fit the stereotype ;)
03:04 PM CaptHindsight: https://en.wikipedia.org/wiki/German_humour
03:04 PM roycroft: seeing you in lederhosen would be humorous, i suspect
03:05 PM CaptHindsight: my experience has been just the opposite
03:07 PM CaptHindsight: the German episodes of Monty Python are some of the funniest sketches I've ever seen
03:08 PM JT-Shop: Major you can't shoot them anymore
03:09 PM gloops: yes very sensitive subject atm over here
03:09 PM JT-Shop: opps
03:10 PM CaptHindsight: gloops: have you see the Netflix series "The Crown"?
03:10 PM gloops: no not seen it Capt
03:10 PM CaptHindsight: https://en.wikipedia.org/wiki/The_Crown_(TV_series)
03:10 PM gregcnc: E was for Effort. measured 70 ohm, so why doesn't it stop?
03:11 PM gloops: hmm looks very good
03:11 PM gloops: shes been a great queen, Elizabeth
03:11 PM CaptHindsight: gloops: half way through binging on season 2
03:12 PM CaptHindsight: interesting perspective on the royal family
03:12 PM roycroft: monty python's fliegender zirkus is not not really german comedy
03:12 PM roycroft: it's english comedy in german
03:12 PM roycroft: i just started watching season 2 last night
03:13 PM CaptHindsight: yeah well whats the name of the really funny German show?
03:13 PM roycroft: it's really tough being queen, in spite of what a lot of people think
03:13 PM CaptHindsight: Queen Elizabeth II's lack of a well rounded education ...
03:13 PM roycroft: and the suez canal crisis was an excellent example
03:13 PM gloops: the new queen elizabeth class carriers look ok
03:14 PM gloops: think theyre about nimitz class size
03:14 PM roycroft: she wanted to smack down the pm because he was being a bellicose jingoistic idiot, but she could not
03:14 PM roycroft: and history tells us who was right in that disagreement
03:15 PM roycroft: hint: the one who was right still has her job
03:15 PM roycroft: half a century later
03:15 PM CaptHindsight: historically it's been pretty accurate so far
03:15 PM CaptHindsight: not sure of all the private dialog
03:15 PM roycroft: yes, it has, historically
03:15 PM roycroft: the interpersonal relationships, a bit embellished for dramatic effect
03:16 PM CaptHindsight: writers embellishment
03:16 PM CaptHindsight: will be interesting to discuss this with some real Brits
03:16 PM gloops: the only thing they watch on netflix in this house is something about witches
03:17 PM roycroft: if they float they are witches
03:17 PM roycroft: if they sink they are not
03:17 PM roycroft: what else is there to know about them?
03:17 PM gloops: 'once upon a time'
03:18 PM CaptHindsight: roycroft: there's an episode ahead that ties King Edward VIII to the Germans pre wwII
03:18 PM CaptHindsight: wikileaks of the 50's
03:19 PM roycroft: haus sachsen-burg und gotha has german ties?
03:19 PM roycroft: whodathunk?
03:19 PM gloops: the name was Saxe-Coburg
03:19 PM roycroft: sachsen-coburg, sorry
03:19 PM CaptHindsight: more than just the name
03:19 PM roycroft: saxe-coburg and gotha is the anglicised name
03:19 PM CaptHindsight: Nazi sympathy
03:20 PM gloops: the royal houses of europe and russia were always connected, diplomatic tactics
03:21 PM CaptHindsight: would be interesting to compare the actual docs, news reports and personal opinions from those around at the time
03:21 PM CaptHindsight: ~1959
03:21 PM CaptHindsight: sure they would intermarry since they were better than all of us
03:22 PM CaptHindsight: it's their divine right
03:22 PM andypugh: WW1 was a war amongst the grandchildren of Queen Victoria
03:22 PM gloops: english prince marries french princess, the offspring are half english - one step closer to owning france
03:23 PM gloops: bargaining chips, leverage in disputes etc
03:23 PM CaptHindsight: I watched Reign so I know all about that :)
03:24 PM gloops: king of englands daughter is married to the french King, Spain invades France, France has an ally
03:25 PM gloops: if you couldnt beat them on the battlefield, you might just beat them with a marriage etc
03:26 PM CaptHindsight: what exactly is a "stiff upper lip"?
03:26 PM SpeedEvil: I did the calculations once, and realised I was only some three hundred deaths and a case of insanity from being king of the UK and sweden.
03:27 PM gloops: well, a stiff upper lip is basically concealing or controlling your emotions
03:27 PM andypugh: CaptHindsight: Never showing any emotion, not allowing a smile.
03:27 PM CaptHindsight: SpeedEvil: so not out of the question
03:28 PM gloops: it was a big thing in the empire days - self control
03:28 PM andypugh: Is it tool late to make it happen now?
03:28 PM CaptHindsight: the lip or SpeedEvil being King?
03:29 PM gloops: one false move at the dinner table, one outburst, any display of anger or fear, you were finished
03:29 PM gloops: if you cant control yourself you have little hope of controlling the world
03:29 PM CaptHindsight: how many semesters does one typically study UK history in the UK?
03:32 PM andypugh: That would depend on what a semester is.
03:32 PM CaptHindsight: growing up in the US and being a newer country, history of the US is pretty short and covered briefly with an emphasis on Pilgrims the Boston Tea Party\Revolution and the Civil War
03:32 PM gloops: well, we dont study uk history much
03:32 PM roycroft: but our president is going to control the world ...
03:32 PM roycroft: just ask him
03:32 PM CaptHindsight: hehe
03:33 PM andypugh: It was compulsory at my school until 14, so only 3 years as a subject at secondary school.
03:33 PM CaptHindsight: where have we heard that before?
03:33 PM CaptHindsight: roycroft: ^^
03:34 PM CaptHindsight: to pas from 8th to 9yh year one must pass a Constitution test
03:34 PM roycroft: is that still a requirement in most states?
03:34 PM andypugh: I remember we spent a fair bit of time looking at recent-ish African history too, though. Like the Mau-Mau in Kenya.
03:34 PM roycroft: i kind of doubt it
03:34 PM CaptHindsight: memorize the answers, take test
03:34 PM roycroft: based on conversations i've had with young people
03:35 PM roycroft: there seems to be very little knowledge of our constitution these days
03:35 PM CaptHindsight: roycroft: it has no connection to how our current form of government operates
03:35 PM roycroft: no, i'm not making any kind of political inference
03:36 PM roycroft: people i talk to seem fairly ignorant of the constitution, and younger people moreso than older people, generally
03:36 PM SpeedEvil: Most people are keen to exercise their 21st amendment rights.
03:36 PM CaptHindsight: how many senators per state? name a right? Have you seen the Schoolhouse Rock episode of how a bill becomes a law? etc
03:36 PM SpeedEvil: Especially important now.
03:37 PM roycroft: when i was in the 7th grade we spent an entire semester studying the constitution, as we were not allowed to advance to high school until we passed a test on it
03:37 PM roycroft: and it was a fairly comprehensive test
03:37 PM CaptHindsight: still here in IL
03:37 PM CaptHindsight: same test
03:38 PM * roycroft will be exercising his 21st amendment rights later on otoday, but has work to do in the shop first
03:38 PM roycroft: yeah, i went to school in illinois
03:38 PM andypugh: It’s so much easier here. We don’t have a constitution. Just 1000 years of habits.
03:38 PM gloops: there doesnt seem to be much intention of instilling national pride in todays youth
03:38 PM gloops: quite opposite in fact
03:38 PM gloops: the
03:39 PM andypugh: National Pride is an odd thing. Why be proud of the thing you have least control of in your life?
03:39 PM roycroft: i'm proud of my national pride
03:40 PM gloops: well, its done us well for long enough, its like the nations immune system
03:40 PM roycroft: my pride is terrific
03:40 PM SpeedEvil: I am proud of my genes. I can only hope that in future we will get closer to the genetic perfection of c.elegans.
03:40 PM roycroft: some say it's the best pride in the world
03:40 PM andypugh: I am extremely grateful to have been born a Yorkshireman rather thanm for example, in Mogadishu.
03:41 PM andypugh: But that’s just a sense of feellng that I got rather lucky in my choice of parents.
03:41 PM roycroft: or they got lucky in where they landed
03:41 PM gloops: i think we were earmarked to be subsumed by the european trading block, thus erasing the national will was necessary
03:42 PM * roycroft should head out to the shop, as there is a lot to do this weekend
03:42 PM CaptHindsight: http://blogs.edweek.org/edweek/curriculum/2016/06/fourteen_states_now_require_gr.html
03:42 PM gloops: the emphasis was placed on international history, and showing us how bad our past really was
03:42 PM CaptHindsight: andypugh: be sure to choose the right parents is the best advice a person can give to a yet to be born
03:43 PM andypugh: gloops: Have you read the Flashman books? Most of the history I know comes form those :-)
03:43 PM gloops: no not read those andypugh, tbh i havent done much reading for some years, only like bedtime reading
03:44 PM roycroft: i was reading an article on huffpost.co.uk the other week that clamed that the british citizenship test was very difficult
03:44 PM andypugh: https://www.amazon.co.uk/Flashman-Papers-Book-1-ebook/dp/B002RI9J2I/ref=sr_1_2?ie=UTF8&qid=1512855803&sr=8-2&keywords=flashman
03:44 PM roycroft: it linked to a sample test, i took it, and scored 85%
03:44 PM CaptHindsight: roycroft: looks like our test is unique to IL
03:44 PM roycroft: if i did that well i don't think it can be that difficult
03:44 PM roycroft: it should be required in every state, capthindsight
03:45 PM gloops: Expelled from Rugby for drunkenness, and none too welcome at home after seducing his father’s mistress, the young Flashman embarks on a military career with Lord Cardigan’s Hussars.
03:45 PM CaptHindsight: nah, too many upstarts to quell :)
03:45 PM andypugh: roycroft: You only need to take it if applying for residency, and I suspect that a lot of folk born here would fail it. Partly because it has some very odd questions.
03:45 PM roycroft: there were a few questions that seemed more appropriate for a trivia contest than a citizenship application
03:45 PM CaptHindsight: look how much easier it is to rule ignorant people
03:45 PM andypugh: gloops: Flashman is not at all nice. But the events he gets tangled up in are interesting.
03:45 PM CaptHindsight: we are almost half way there
03:46 PM roycroft: i'm convinced that's why republicans want to abolish publica education, capthindsight
03:46 PM CaptHindsight: oh sure
03:46 PM roycroft: an educated populace would never vote for them
03:47 PM gloops: the problem is the bulk of the population cannot be educated
03:47 PM CaptHindsight: uneducated, the abused and the selfish
03:47 PM roycroft: i disagree
03:47 PM roycroft: i might agree that the bulk of the population belive they cannot be educated
03:47 PM gloops: look at huxleys 'brave new world'
03:47 PM roycroft: and i don't believe it's necessary for the entire population to have post-graduate degrees
03:48 PM roycroft: nor even a basic college degree
03:48 PM CaptHindsight: but not a bad idea
03:48 PM roycroft: an honest high school education is fine for most
03:48 PM gloops: that is provided
03:48 PM roycroft: no it's not
03:48 PM CaptHindsight: with an actual education
03:49 PM gloops: who decides what to teach them?
03:49 PM roycroft: people graduate from high school (large numbers of people) who cannot read
03:49 PM roycroft: or solve simple arithmetic problems
03:49 PM CaptHindsight: schooling vs education
03:49 PM gloops: they dont want to read, their parents dont care if they can read or not
03:49 PM roycroft: that's part of the problem
03:49 PM roycroft: i won't deny that
03:50 PM CaptHindsight: I had a friend that asked to learn how to read when he was picking his first college courses
03:50 PM roycroft: education can be quite challenging
03:50 PM CaptHindsight: made it through the LA county schools
03:50 PM gloops: in some social stratas anything distributed by authority is regarded with suspicion and rejected
03:50 PM CaptHindsight: for 12 years and could not yet read
03:51 PM roycroft: but when funding for public education is slashed and taxpayer money is provided to parochial schools that do more indoctrination than education, that does not bode well for our future
03:51 PM Deejay: gn8
03:51 PM roycroft: keep in mind that in the united states, there is still a big argument about whether global climate change is an actual thing or not
03:52 PM roycroft: we're not arguing whether it's human caused or not
03:52 PM roycroft: we're still arguing its existence
03:52 PM andypugh: Errr… Milling! Lathes! G43 M10….
03:52 PM roycroft: as an example of what indoctrination does
03:52 PM andypugh: (Isn’t this the LinuxCNC IRC?)
03:53 PM * roycroft heads to the shop to get some work done before exercising his xxi amendment rights
03:54 PM gloops: wow my google is loaded with history and politcs links lol
03:54 PM gregcnc: I guess I have to check to see if the drive is erring. It brakes quickly to a point, then seems to coast.
03:55 PM gregcnc: the lenze manuals are crazy big, but the resistor should be 155 Ohm vs the installed 68.
03:55 PM CaptHindsight: gregcnc: maybe whatever hunk of silicon is opening when hot vs the resistor?
03:56 PM CaptHindsight: 68 means more current and heat, and more for the *fet to handle and thermal protection kicks in
03:56 PM CaptHindsight: just a theory
03:56 PM gregcnc: right could be the resistor switches aren't working
03:56 PM gloops: archivist showed me some interesting links earlier, re rotary axis tracking an X,Y path
03:56 PM CaptHindsight: modern motor drivers tend to have built in temp protection
03:57 PM CaptHindsight: the resistor will expand when heated... maybe it is also opening when hot
03:57 PM gloops: which i intend to get into, once ive done making this machine
03:58 PM gregcnc: next step is check for lights and measure voltage on the brake resistor.
03:59 PM CaptHindsight: gregcnc: challenging when it's a short term condition vs continuous
03:59 PM CaptHindsight: gregcnc: have to plan your observations accordingly
04:00 PM CaptHindsight: first thing i still do is check for mechanical issues with circuits
04:00 PM CaptHindsight: wiggle, shake, tap with back of screw driver etc
04:01 PM CaptHindsight: poor solder connections, lose connectors, etc
04:02 PM CaptHindsight: industrial components tend to be made better than consumer but with intermittent problems they most often are still mechanical failures
04:03 PM CaptHindsight: unless you see that the smoke has been released or carbon connections
04:04 PM CaptHindsight: gloops: I came across sets of old mathematics books pre-1950
04:04 PM gloops: surely algebra was the same then as it is now?
04:04 PM CaptHindsight: they are some of the most clearly written on the subject from basic operations through calculus I've ever seen
04:05 PM gloops: hmm, you might have a point there
04:05 PM CaptHindsight: heh, no here it requires new books every few years
04:05 PM CaptHindsight: I actually went through this with the courts here and my kids
04:05 PM CaptHindsight: it's insane
04:06 PM gloops: this is fascinating - emc2 5 axis https://www.youtube.com/watch?v=fWKYQUj5AOs
04:06 PM gloops: by cradek
04:07 PM CaptHindsight: I still point to his videos with customers about new machines
04:07 PM CaptHindsight: why we use LCNC
04:09 PM gloops: i havent yet got how a rotary like that is synchronised with the other axis, its like focused on the centre point of the circle or cylinder
04:09 PM CaptHindsight: https://www.youtube.com/watch?v=FpaywPSqsbo G-code driven machine tool simulation of 5-axis machining and indexing. EMC2 controller build inside NX with CSE simulation.
04:10 PM CaptHindsight: I see NX and g-code....
04:11 PM gloops: whats NX
04:12 PM CaptHindsight: high end CAD/CAM
04:12 PM gloops: ahh right
04:12 PM CaptHindsight: https://en.wikipedia.org/wiki/Siemens_NX
04:13 PM gloops: archivist mentioned setting up the rotary in kins, so you can make a formula for its positioning relative to the movement of the other axis, throughout the g code program?
04:14 PM gloops: i.e not have to code the rotaries over move
04:14 PM gloops: rotarys every move
04:20 PM CaptHindsight: roycroft: I'm all for brewing 101 as a HS graduation requirement. Math, bio, chem, and civics all in one :)
04:24 PM SpeedEvil: physics
04:26 PM rene-dev: CaptHindsight do you have a 5 axis linuxcnc post for nx?
04:43 PM CaptHindsight: rene-dev: yes
04:44 PM CaptHindsight: rene-dev: sorry, not for Linuxcnc
04:45 PM CaptHindsight: don't have NX on Linux either
04:48 PM rene-dev: ah. 3 axis works, but never looked into 5 axis machining.
05:51 PM XXCoder: https://community.plus.net/t5/Plusnet-Blogs/App-y-Endings-Films-that-would-have-turned-out-better-with/ba-p/1385478
06:20 PM Tom_L: i wonder what i did to my setup to cause the jog speed selector on my pendant to not select
06:29 PM gregcnc: capthidsight brake resistor gets current on braking. the drive doesn't seem to be tripping. This drive doesn't have a display so not much to go on and can't check parameters.
07:12 PM SpeedEvil: https://www.youtube.com/watch?v=-oB6DN5dYWo how to drive a fork lift truck in germany

07:57 PM CaptHindsight: Have one to sell? Sell now
07:57 PM CaptHindsight: Details about portable comver milling machine
07:57 PM CaptHindsight: maybe it's by trump?
07:57 PM CaptHindsight: comver?
07:58 PM gregcnc: i'm not sure that that thing is supposed to do
07:58 PM CaptHindsight: might be the other person in China with a sense of humor
07:58 PM XXCoder: so cheap
07:58 PM CaptHindsight: Welding joint of ship deck can be cut processed
07:58 PM CaptHindsight: the two ends of the bottom switch of the permanent magnet is fixed on the deck
07:58 PM CaptHindsight: the cutting force,more than unilateral feed 5mm
07:59 PM gregcnc: didn't solve my braking problem. I suspect the drive parameters are not factory
07:59 PM XXCoder: gregcnc: looks like pipe maker weld machine
07:59 PM XXCoder: or maybe not
07:59 PM CaptHindsight: have to check the bottoms of scotch bottles for secret messages, bbl
08:01 PM XXCoder: our president just did a rally
08:01 PM XXCoder: umm
08:01 PM SpeedEvil: Did he declare that tiawan was always part of china
08:34 PM roycroft: he declared that it's better to date young girls than to be a democrat
08:34 PM roycroft: so there's that
08:36 PM XXCoder: yeah its just recent addition to collection of stuff he said that should have ended his bid of presidency or ended his presidancy but does not
08:37 PM XXCoder: would it surpise you that few super republician deaf people voted for him after his mocking of disabled reporter?
09:18 PM XXCoder: JT-Shop: you there?
09:43 PM rebecca_: anyone tried any of the ATC spindles on aliexpress?
09:44 PM jdh: aren't they really pricey?
09:44 PM jdh: for unknown chinese fairly complicated devices?
09:44 PM rebecca_: well, they are less pricey than european manufactured ATC spindles
09:47 PM rebecca_: and as for unknown.. that's why i'm asking
10:21 PM rebecca_: jdh?
10:37 PM jdh: no clue. just a lot of money for an alibaba item
10:40 PM rebecca_: indeed
10:42 PM rebecca_: i know how useful an ATC CNC is and i'm spooling up a CNC based business. so the expense is justified. but.. yeah. i know it's a risk buying from there
10:58 PM * hazzy has been out shoveling snow in the cold and dark
10:58 PM hazzy: Our neighbors workshop roof collapsed completely and the garage mostly collapsed from the weight of 4-5in of very wet snow/sleet + rain.
10:58 PM hazzy: Her husband just died, so she was not paying attention to the build up like he would have, and I was plying in the shop :(
10:59 PM hazzy: Were able to get enough weight off the garage to jack the roof up and get the cars out. Will rescue the shop equip in the morning.
10:59 PM rebecca_: hazzy: ouch
10:59 PM hazzy: Yes, very sad
11:04 PM rebecca_: can the structure be salvaged or it needs to be completely rebuilt?
11:07 PM hazzy: I think the we can get away with jacking the garage back up and replacing the beams, the workshop unfortunately is very badly damaged and I think will need to be completely rebuilt. The mornings light will tell for sure
11:07 PM * rebecca_ nods
11:08 PM rebecca_: where in the world is this?
11:09 PM hazzy: Atlanta, Ga USA, were we only get snow once in a blue moon, hence the buildings aren't designed to support the load
11:09 PM rebecca_: ahhhh
11:10 PM rebecca_: im in australia. the idea of snow crushing a building boggles my mind
11:12 PM hazzy: Haha, yes!
11:16 PM roycroft: in the us, the idea of a 'roo smashing a truck boggles the mind
11:17 PM hazzy: Very true roycroft, in fact that possibility had not even crossed my mind!
11:17 PM roycroft: they cause a lot of damage to trucks
11:17 PM rebecca_: hehe, yup
11:17 PM hazzy: I guess kinda like deer and elk here
11:18 PM roycroft: yeah
11:18 PM roycroft: except deer and elk are a bit more predictable
11:18 PM hazzy: For the British car lovers here, one of the rescued cars is a 1937 AC in fine condition, seen here with the late owner at the wheel: https://i.imgur.com/ZNA34vf.jpg
11:18 PM roycroft: so i don't think it happens as often here
11:18 PM hazzy: He bought the car when it was about 15 years old and he was a young chap of 17 growing up in the UK. He loved that car dearly and when he moved to the US brought it with him.
11:19 PM hazzy: roycroft: Yeah deer walk properly!
11:19 PM roycroft: well
11:19 PM roycroft: they tend to stay away from roads except at feeding time
11:20 PM roycroft: and in the northwet, at least, they tend to travel along l=known routes
11:21 PM roycroft: i see a lot of deer on my way to work, especially this time of year, but i know where to look for them, and i've never come even close to hitting one
11:21 PM roycroft: i've had to stop and wait for them to get out of the way many times
11:21 PM hazzy: I don't know, the deer here in the city are crazy, they will just head across the freeway any time of day and night, and seem completely oblivious
11:22 PM hazzy: They city deer are almost different animals though, their instincts are so messed up
11:23 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Z_Column2.jpg
11:23 PM roycroft: yeah, i live right on the edge of city limits, and my morning commute is away from the city
11:23 PM roycroft: so i deal with country deer, not city deer
11:24 PM hazzy: Looking good Tom_L!
11:25 PM hazzy: Why does the column have an angled cut at the top? :P Or is that just the camera play tricks on me?
11:26 PM Tom_L: ? which one
11:26 PM Tom_L: i need to square one up a bit
11:27 PM Tom_L: i'd had enough by then
11:27 PM Tom_L: and just a sharp edge on one
11:27 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Z_Column1.jpg
11:30 PM hazzy: Are you using a bandsaw for the cuts? Some of that has a decent wall
11:30 PM Tom_L: angle grinder
11:30 PM Tom_L: i don't have a bandsaw
11:32 PM hazzy: Oh, boy, that looks supper then! It takes patience to do that with a grinder
11:33 PM rebecca_: oooh, building a vertical mill?
11:34 PM Tom_L: hazzy, that 4" tube wasn't as bad as i thought it was gonna be
11:34 PM Tom_L: it's fairly square too
11:37 PM hazzy: Yeah, you can do accurate work with a grinder, it just takes time and a little patience (with it looks like you have!)
11:37 PM hazzy: I am so spoiled by my bandsaws it is not even funny, it is causing me to loose all my ingenuity
11:37 PM hazzy: I have been know to even cut hard crusted bread on the bandsaw ...
11:38 PM Tom_L: i don't go to the gym, i go to the garage :)
11:40 PM hazzy: That is good, with the saved gym free you can buy linear rails etc, make some awesome machines and have more fun, AND get a work out!
11:40 PM hazzy: (That only works until you build too many labor saving machines :D)
11:41 PM hazzy: OK, I am off to warm shower and bed
11:41 PM hazzy: gn8
11:42 PM Tom_L: good plan
11:44 PM MarcelineVQ: as long as your zipdisks aren't exploding you can get all kinds of work done with a grinder :>
11:44 PM roycroft: a band saw is a lot more quiet and gentle than a grinder
11:44 PM roycroft: i use both
11:45 PM roycroft: but i'll use a bandsaw any time i can
11:45 PM Tom_L: MarcelineVQ i mustuv gotten some good ones cause i was pretty rough on them tonight
11:45 PM MarcelineVQ: bandsaws are a joy. would love a little vertical/horizotnal, space is premium here though :X
11:45 PM roycroft: i used to have a 4x6
11:46 PM roycroft: but now i have a 7x12, which is a really nice size
11:48 PM roycroft: but i used to be able to schlep the 4x6 out to job sites in my van
11:48 PM roycroft: the 7x12 is way too big and heavy for that
11:48 PM roycroft: i see a battery powered portaband in my future though
11:48 PM MarcelineVQ: they make little handheld bands now that are quite cool
11:49 PM MarcelineVQ: good for tubing and such ehe
11:49 PM roycroft: a couple years ago i started converting my battery tools to milwaukee 18v
11:49 PM roycroft: because their portaband is awesome
11:49 PM roycroft: the battery one is more powerful than the corded one
11:50 PM roycroft: https://www.milwaukeetool.com/power-tools/cordless/2729-22
11:50 PM roycroft: i don't have that yet, but it's on my short list
11:50 PM MarcelineVQ: I can believe it, can get a lot of torque out of a battery pack. I've heard that you get less recharges the more amps a pack can put out though, some sort of innate tradeoff
11:50 PM roycroft: that, plus the fuel series uses brushless motors
11:51 PM rebecca_: mmmmm brushless
11:52 PM MarcelineVQ: roycroft: how do you do such a conversion? or do you mean you're replacing units as they age which slowly converts your collection
11:53 PM roycroft: yeah, i just started buying new milwaukee tools
11:53 PM roycroft: and stopped buying batteries for the old dewalt stuff
11:55 PM MarcelineVQ: some of that old stuff sure is reliable, we've had a cordless drill sitting in a bucket of water for.. 3 months :X once I freed the chuck it was back to work
11:55 PM MarcelineVQ: *cordless dewalt
11:55 PM MarcelineVQ: And I literlaly mean sitting in a bucket with water, it was left out in the rain down by a pond :O
11:55 PM roycroft: my first battery tool was a 7.2v makita drill that i bought in the mid to late '80s
11:56 PM roycroft: i still have it
11:56 PM roycroft: and the original two batteries i got for it still work
11:56 PM roycroft: i like to pull it out once/year or so and use it just to prove that it still works
11:56 PM MarcelineVQ: roycroft: that's scary good battery reliability
11:56 PM roycroft: it has two speeds - slow and not quite so slow
11:57 PM roycroft: yeah, especially for batteries of that era
11:57 PM roycroft: i can't believe they still work
11:57 PM roycroft: my dewalt batteries only last 3-4 years at most
11:58 PM roycroft: the makita batteries are nicad
11:58 PM roycroft: dewalt nimh
11:58 PM roycroft: milwaukee are lithium ion
11:58 PM roycroft: my oldest milwaukee 12v stuff is about 6 years old now, and the batteries still take full charges
11:59 PM roycroft: the oldest milwaukee 18v stuff is about 3 years old now, so a bit soon to tell how long they'll last
11:59 PM roycroft: i don't use my battery tools all day, every day
11:59 PM MarcelineVQ: I've only just now gotten my first coldless stuff, can only hope for half the life-times you're citing ehe
11:59 PM roycroft: i don't make my living with them
11:59 PM roycroft: but i do use them a lot
11:59 PM roycroft: i'm really really impressed with the milwaukee fuel line
11:59 PM roycroft: they're expensive, but they're really powerful and very well balanced
