01:57 AM gloops: vertical dovetails and box joints must be cut from both sides, to avoid breakout from the cutter passing through
02:00 AM gloops: that means - hand coded
02:00 AM gloops: and that means thinking about it, which is something im not used to
02:05 AM gloops: actually i think i can do this with software, instead of pocketting, i can cut a series of lines from either direction
02:07 AM XXCoder: wouldnt you be able to deburr it anyway? or is breakout something different
02:07 AM XXCoder: also wouldnt you just enter then leave both sides so end up with no breakout
02:09 AM gloops: with wood theres a good chance it will chip or splinter when coming out, it needs to enter the face on both sides cutting in
02:09 AM gloops: i got the sim working with cutting lines - any pocket i try to cut it always leaves cutting out
02:12 AM XXCoder: cool :)
02:19 AM gloops: can see there how hes took out the breakout points before cutting through https://www.youtube.com/watch?v=toMPVw-TQbo
02:20 AM Deejay: moin
02:21 AM gloops: morning
02:22 AM XXCoder: thats nice
02:54 AM gloops: yep got that working, still some arithmetic and use of array and copy etc but quicker than hand coding
02:55 AM miss0r: mornin'
03:03 AM XXCoder: nice. hey
03:09 AM gloops: rain all day here
03:09 AM XXCoder: same
03:10 AM XXCoder: here is experencing very dry season so far
03:10 AM XXCoder: only 1 or 2 rains a week when normally its rain in least once everyday at early fall
03:15 AM gloops: it was like that here earlier in the year - getting back to normal now
03:15 AM gloops: although 20c forecast next week - a good bit higher than average i think
03:17 AM gloops: 20C is like outdoor swimming weather, getting towards winter now
03:17 AM XXCoder: 68f interesting
03:17 AM XXCoder: here its all week below 60f
03:18 AM gloops: if its going to be hot every year ill have to move north, i seriously cant stand it
03:19 AM XXCoder: heh cold weather body here, summers suck for me
03:23 AM gloops: 70-80F - very nice, 80-100F+ - you can keep it lol
03:23 AM XXCoder: lol
03:24 AM XXCoder: here summer in that range tend to last 6 to 8 weeks
03:37 AM miss0r: I just got my new tool box.. My leather midwife style bag is starting to also allow for larger tools to fall out the holes in the bottom :) So, now I am replacing it
03:37 AM miss0r: i've had it for 20 years.. :)
03:38 AM miss0r: the new one has pneumatic/hydraulic cylinders to help open and keep the lid open :D
03:47 AM XXCoder: nice
03:52 AM miss0r: the only thing that sucks about this.. A new tool box; now I can't find anything :)
04:20 AM gloops: well, another cup of tea then to the garage
04:22 AM miss0r: gloops: What are you up to?
04:26 AM gloops: miss0r starting making a bandsaw for slicing logs - also got a dovetailing jig i made to test with some gcode
04:26 AM miss0r: nice. What does that dovetail jig look like? is it for the router?
05:08 AM jthornton: morning
05:10 AM XXCoder: hey
05:11 AM jthornton: I still haven't tried to boot to windoze on this laptop lol
05:15 AM XXCoder: I wonder if you need a grep rescan'
05:15 AM XXCoder: umm not grep forgot name of it
05:15 AM jthornton: what does that do?
05:15 AM XXCoder: it checks your system for bootable partions and rebuilds your boot menu
05:16 AM jthornton: I'm on Linux Mint 18 now
05:17 AM jthornton: can't seem to get google to work as default for firefox and yahoo sucks
05:17 AM XXCoder: ah yes! grub
05:17 AM XXCoder: you need to go to website to add google
05:17 AM XXCoder: its annoying
05:18 AM XXCoder: https://www.linuxmint.com/searchengines/anse.php?sen=Google&c=y
05:19 AM XXCoder: steps if it dont seem to work https://connectwww.com/how-to-add-google-search-option-in-firefox-on-linux-mint/4884/
05:22 AM jthornton: finally got it, damn pain in the ass
05:23 AM XXCoder: yeah
05:24 AM gloops: slight power issue there..windows doesnt handle being switched off very well
05:25 AM jthornton: I'd reboot now but I'm testing some chicken python code
05:25 AM jthornton: code needs to adjust the open and close time of the door each night at midnight + 1 minute
05:27 AM gloops: to keep up with changing daylight times?
05:27 AM jthornton: aye
05:28 AM jthornton: door must close at dusk and for now open at dawn until 10 hours of daylight then start adding extra light
05:29 AM gloops: so youll need something to control the lights
05:30 AM jthornton: I'm using a RPi with a terminal block plugin thing and a relay block
05:31 AM jthornton: I have a RPi now controlling the door and lights but I'm trying to improve the code
05:38 AM jthornton: the other thing I'm trying to sort out is how to ramp up the light time from a date 5 minutes per day until I reach 14 hours then hold that light time
06:01 AM gloops: last cutting disc burns away at this stage of proceedings
06:19 AM Tom_L: 55°F Hi 56 hmm, that doesn't sound good
06:20 AM Tom_L: neither does the weather map
06:20 AM XXCoder: 57f high here
06:33 AM gloops: hmm, i am foreseeing problems with this bandsaw now
06:33 AM Tom_L: how so?
06:33 AM gloops: if this 'gantry' racks, the blade is gonna come off
06:33 AM gloops: https://www.youtube.com/watch?v=K2wLdhZjKBM&t=37s
06:33 AM XXCoder: that looks so safe
06:33 AM gloops: hes using a big handle to push both sides the same time, i reckon ill have to do that
06:34 AM Tom_L: you making one of those?
06:34 AM gloops: XXCoder lol, bandsaws arent that dangerous
06:34 AM gloops: Tom_L similar idea, i got a scrap bandsaw to start with, so got the wheels and tensioners and everything
06:35 AM gloops: it just dawned on me, if the gantry racks the blade will just slip off
06:35 AM XXCoder: yeah rhats why I was being sarastic on it being safe
06:35 AM Tom_L: the guides should keep it on
06:36 AM XXCoder: tenitis special https://www.youtube.com/watch?v=EXG3vaM5HlM
06:36 AM gloops: Tom_L maybe, but if one side is twisted at a different angle..it takes ages to trim the wheels to get the blade to run on track
06:37 AM gloops: blade making is a huge pastime now
06:37 AM Tom_L: looks like he adjusts the height on each side separately
06:38 AM gloops: yeah ive got two old vertical screw jacks for that, ill just raise and lower each side on those
06:38 AM Tom_L: seems it would be harder to get even cuts
06:38 AM gloops: ive got 1 piece of 6 inch box section for the spine of it
06:39 AM Tom_L: i suppose he planes them flat after that
06:39 AM gloops: yeah, put them through planer thicknesser when dry - or surface them on cnc router
06:39 AM Tom_L: and sawdust collection in the tracks will affect the board thickness too
06:40 AM Tom_L: i'd address that problem as you build it
06:40 AM gloops: im running mine on skate bearings along two pipes
06:40 AM XXCoder: brushes tp move chips out of way would work fine
06:40 AM XXCoder: just use paintbrushes very cheap ones cut off handle and screw it in
06:41 AM gloops: i think he improved that machine a lot in later videos, but daft as it looks, oak boards like that are expensive, hes shelling off $20 a time there
06:42 AM Tom_L: i know
06:42 AM XXCoder: oak takes a bit to grow
06:43 AM XXCoder: that video is interesting so far
06:44 AM Tom_L: https://www.youtube.com/watch?v=Z7Kt3IrTBlA
06:44 AM Tom_L: he collects some of the chips in a bucket
06:45 AM gloops: thats what you want yeah
06:46 AM gloops: the dust will run with the direction of the blade on the bottom - always comes out same end
06:47 AM gloops: thats a ood set up on a trailer - straight to the wood
06:47 AM gloops: good
06:49 AM gloops: quarter sawn hardwood - get your chequebook out
06:49 AM Tom_L: or your saw
06:49 AM gloops: lol, well see if i can get this crazy idea to work
06:50 AM Tom_L: not crazy unless it fails
06:50 AM Tom_L: i kinda like that trailer saw
06:51 AM gloops: that is an ideal way to do it yes
06:51 AM gloops: tree blown down? hitch up the saw off you go
06:52 AM Tom_L: now that jthornton's got a few wood tools i feel he needs to build one of those :D
06:52 AM Tom_L: and the forest to go with it...
06:53 AM gloops: useful thing to have
06:56 AM Tom_L: those last few cuts he does are the 'money' cuts
06:58 AM XXCoder: the decreasing sizes cuts?
06:58 AM jthornton: Tom_L: what's that?
06:58 AM Tom_L: https://www.youtube.com/watch?v=Z7Kt3IrTBlA
06:58 AM Tom_L: bandsaw mill
06:58 AM XXCoder: is it part where he cuts turn it cut, turn back so on?
06:59 AM Tom_L: i believe so yes
06:59 AM jthornton: my neighbor has one
07:00 AM XXCoder: jthornton: did you see video I linked to? he vbuys a bucket of rusty tools for a dollar
07:00 AM XXCoder: restores em
07:00 AM jthornton: that one is too short
07:00 AM jthornton: missed that
07:01 AM XXCoder: tenitis special https://www.youtube.com/watch?v=EXG3vaM5HlM
07:01 AM jthornton: my neighbor says the center wood is no good
07:03 AM jthornton: that's why saw mills make landscape timbers from the center
07:04 AM veek_ is now known as veek
07:04 AM jthornton: well I'm going to try and boot to windblows now
07:04 AM XXCoder: fixed grub?
07:04 AM XXCoder: bah late
07:13 AM jthornton: took two tries but I've booted to windblows
07:13 AM XXCoder: yay
07:13 AM XXCoder: so you fixed grub eh
07:13 AM jthornton: clock is off
07:13 AM jthornton: didn't do anything to it
07:14 AM XXCoder: if I recall linux simply ignores board clock besides using it to keep time syched
07:14 AM XXCoder: so board time mau be off
07:17 AM jthornton: I'm in windblows at the moment
07:17 AM jthornton: time to switch back to linux
07:22 AM jthornton: back at Linux Mint so all that is working now :)
07:23 AM XXCoder: so whats you do? use grub scan or soemthing?
07:24 AM jthornton: nothing, just rebooted a few times
07:24 AM jthornton: figured out to do nothing instead of pressing F12 or Del lol
07:25 AM XXCoder: lol
07:26 AM robotustra: seflcure os
09:12 AM gloops: no cnc building going on then
09:14 AM syyl: when your customer requests scraped surfaces just for the heck of it, haha
09:14 AM syyl: http://gtwr.de/div/scraped.jpg
09:15 AM syyl: ...
09:21 AM gloops: pretty
09:48 AM SpeedEvil: :)
10:08 AM Tom_L: jthornton what windows ver are you dual booting?
10:43 AM skunkworks: dads back to sawing lumber...
10:44 AM Tom_L: i was sawing logs all night :)
10:44 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/valenite/Collet.jpg
10:44 AM Tom_L: now i need a cnc lathe
10:45 AM syyl: looks more like a lot of grinder work ;)
10:45 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/valenite/valenite_holder1.jpg
10:46 AM Tom_L: i'm not sure the kenametal ones are the same
10:47 AM Tom_L: http://www.tools-n-gizmos.com/specs/DA_Collet.html
10:47 AM Tom_L: http://www.tools-n-gizmos.com/store/agora.cgi?user2=yes&p_id=19582&xm=on&ppinc=1a
10:47 AM Tom_L: that looks close
12:02 PM fragalot: hey
12:10 PM gloops: evening
12:15 PM gloops: missed a good sunset by the look of it
12:42 PM fragalot: miss0r: got the new drill press. I'm sure the table alone weighs 100kg+ https://photos.app.goo.gl/ZTjRYbu79rBEEJRw8
12:44 PM fragalot: miss0r: I believe the table might have been part of a 5-axis mill.. gears & bearings have been recently replaced by previous owner, just before he 'upgraded to an RF30'
12:52 PM hetii: Hi guys :)
12:54 PM gloops: evening
12:55 PM gloops: that looks a bit 'machinemart' fragalot
12:58 PM hetii: I whant to build my first CNC machine for milling as a hobbyist PCB or maybe some front panels for my devices. So far I order such items square Linear guide sets: goo.gl/hV6etv and 2.2kw water spindle: goo.gl/WTokXw. Now wonder about step motors, this one will be fine? goo.gl/tJofau
12:59 PM hetii: btw the table and rest will be made from wood
01:01 PM gloops: yes i think so hetii
01:02 PM gloops: ive got the same on mine basically
01:03 PM gloops: btw you need a different breakout board that one wont operate the spindle
01:03 PM gloops: it is only a $5 thing
01:03 PM fragalot: gloops: machinemart?
01:03 PM gloops: cheapo chinese?
01:03 PM hetii: I also found such motors: http://goo.gl/bDz2EE but they have higer impedance
01:04 PM fragalot: gloops: if you can call a €3000 drill press 'cheapo', sure
01:04 PM fragalot: it feels pretty good, so no complaints from me :-)
01:04 PM gloops: what that? never
01:04 PM fragalot: other than it being a BASTARD to lift
01:05 PM gloops: hetii i think 425Oz-in is a typo
01:05 PM gloops: theyre 425 oz
01:06 PM fragalot: gloops: mine's the "pre sold out to china" version. this is the china version you can get today: https://www.huvema.nl/nl/tandwielboormachine-hu-25-tn-4-11283
01:06 PM hetii: gloops, so with one order, the first one based on 23HS9442 or the second one on 23HS2430B ?
01:06 PM fragalot: less gears available, lower power motor, and thinner column
01:06 PM fragalot: so I'm pretty happy :-)
01:07 PM gloops: what are you getting for 2k there?
01:07 PM fragalot: small format gear drill press
01:07 PM fragalot: the one I have has a 180mm quill travel, rpm range from 100 to 3000
01:07 PM gloops: hetii im not an expert on individual motors of this kind, they both look ok tbh, pretty standard issue steppers
01:07 PM fragalot: and because of the head moving instead of the table, the damn thing is rigid as hell
01:08 PM gloops: still seems expensive to me, but what do i know
01:08 PM hetii: Well I just read that lower impedance motor are faster
01:08 PM fragalot: hard to find cheaper geared drill presses, gloops
01:08 PM hetii: but cannot say about other pros or cons
01:10 PM gloops: https://www.ebay.co.uk/itm/Fobco-Pillar-Drill-3-phase-2mt/302909369620? i mean these are known for being top notch drills
01:10 PM fragalot: belt driven, and not benchtop size
01:10 PM fragalot: whole different class of machine
01:11 PM hetii: about board what you suggest to use for linuxcnc? I would like to start from LPT, and if need more GPIO then can add second LPT port or build some usb2gpio module based on AVR
01:11 PM fragalot: hetii: i'd suggest that if you can, that you go with mesa cards instead of LPT
01:11 PM gloops: personally id go with the first motors hetii, 2 psus
01:12 PM gloops: i wouldnt go with mesa for first cnc, it will be hard enough to get it running from lpt
01:12 PM gloops: you want the mach3 board hetii, hang on
01:13 PM hetii: well i`m not sure if I need use mach3 software, personally I use linux all the time so preffer linux based software
01:13 PM gloops: https://www.ebay.co.uk/itm/Cnc-5-Axis-Interface-Breakout-Board-For-Stepper-Motor-Driver-Cnc-Mill-Mach3-MB/142907628409?
01:14 PM gloops: yeah its just commonly known as the mach3 bob
01:14 PM gloops: it works on any software
01:14 PM gloops: exactly that board, not the blue one
01:15 PM gloops: this has got pwm and relay for the spindle control, the 1205 board in that package doesnt - you cant control the spindle with it
01:16 PM gloops: as used by the late and great Ichsguckslive who came here for 10 years or more
01:16 PM gloops: he built 200+ machines a year with this board
01:17 PM Tom_L: that one has analog spindle control?
01:18 PM gloops: you got the pwm for spindle speed and relay on/off
01:20 PM hetii: gloops, about electronics things I can create any board that I will need, so suppose this will not be a problem for me. Of course not including FPGA for driving motors but here I will use lpt and other things for the rest
01:20 PM Tom_L: good board for the 7i92..
01:21 PM gloops: not worth making for $5 but im sure your skills will be useful
01:21 PM hetii: btw I also plan to control all parameters of VFD spindle from PC
01:21 PM hetii: so can write even additional software for it
01:21 PM hetii: if needed
01:21 PM gloops: yes thats what im saying
01:22 PM gloops: you can control the spindle from linuxcnc - ui and or gcode with that board
01:23 PM hetii: ok so have a next question about LinuxCNC sofware, is it expose some API system that I can call and add for example some cameras inside my CNC machines that will recognize object by using https://opencv.org/ library and based on those data do some positioning
01:24 PM hetii: so for eg by opencv I could detect edges or my material
01:25 PM gloops: yes i think so
01:26 PM gloops: you might need 2 parports if you start adding more hardware
01:27 PM gloops: a lot of these questions are answered on the forum
01:27 PM hetii: yep, simple hardware with IOs capabilites will not be a problem :)
01:29 PM gloops: https://pico-systems.com/centcam.html
01:29 PM gloops: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Adding_Digital_Zoom_To_Camview-Emc
01:31 PM hetii: cool ok, so first I need to build my machine and then will add new stuff to it ;)
01:32 PM gloops: any design ideas for the mechanical build?
01:34 PM hetii: well, this is a subject where I need to learn more ... But suppose at the end, the gate will be static and I will just move table.
01:35 PM gloops: probably as well if building with wood
01:36 PM hetii: yep but I have 1m and 70cm linear guide and in my setup I plan to use 70cm for X and 1m for Y
01:37 PM gloops: id think it makes sense to have the bridge the shorter dimension
01:37 PM gloops: for rigidity
01:37 PM hetii: and all will be build like here http://i0.wp.com/i.pinimg.com/736x/5a/c7/72/5ac77257a880a387455831bb56e3120d--homemade-cnc-cnc-wood.jpg
01:39 PM hetii: well.. my plan to exchange X an Y is because i`m not sure if I will have enough space my my desk :)
01:40 PM hetii: but from rigidity perspective you have right
01:43 PM hetii: BTW, I also I plan to add there 3D head and 15W Laser that why I want to have closed box and cameras inside and control my machine over LAN
01:43 PM hetii: so don`t need to have glass window in it
01:44 PM gloops: hmm, a 3 in 1 machine
01:44 PM gloops: i wished id built mine vertical now to save space
01:44 PM hetii: yep
01:48 PM gloops: Loetmichel made a few wooden machines, still uses one i think
01:48 PM gloops: he cuts aluminium with it
01:55 PM hetii: gloops, back to board, why blue one is broken ?
02:05 PM gloops: ahh yes, i thought you might ask that
02:05 PM Loetmichel: gloops: i dont use a wooden machine any more, but yes, cutting alu on a wooden cnc router is perfectly doable if you make the gantry rigid enough
02:06 PM gloops: i remember seeing some vids you posted of the plywood machine Loetmichel, worked fine
02:06 PM Loetmichel: indeed
02:06 PM Loetmichel: and not a small one ;)
02:07 PM Loetmichel: https://www.youtube.com/watch?v=-iYhICZEsCA <- that video?
02:09 PM gloops: yeah look at that, better than a lot of chinese ones you can buy
02:10 PM hetii: well in my case when I talk about aluminum I suppose it will have something like 1.5mm thickness
02:11 PM hetii: so I really don`t plan to milling a car :)
02:11 PM gloops: 2.2kw spindle will eat it
02:12 PM hetii: and also wonder if I should order some machine like CNC3040 from aliexpress but I read that is to soft and not capable for my easy tasks
02:13 PM hetii: so I decide to build it from wood
02:13 PM Loetmichel: hetii: i do a lot of 1,5mm Alu on a cheap chinese CNC 6040 at the company
02:13 PM Loetmichel: works fine
02:13 PM Loetmichel: https://www.youtube.com/watch?v=m7eO5cu-fXg <- desk its mounted on could be a bit more stiff though ;)
02:13 PM hetii: I`m a bit scary at the moment cause the plan was to have small machine and I end with huge one
02:14 PM gloops: mine does cut ally - slowly, but ive only got 800w spindle
02:14 PM gloops: thats the bottleneck
02:14 PM Loetmichel: not here
02:14 PM Loetmichel: the 800W spindle still has loads of torque reserves when the gantry starts to bend
02:15 PM hetii: wow, why this machine so dancing :)
02:15 PM gloops: well mine doesnt exactly rip it up with aluminium
02:15 PM Loetmichel: Whats the word for "springy bend, returns when force is no longer applied?"
02:15 PM gloops: makes a very nice job though
02:16 PM Loetmichel: hetii: word of advice: if you have ANY chance to make room for a 6040 sized machine: do it. The 6040 is a lot stiffer than the 3040 because of using supported rails in Y
02:17 PM gloops: good with mdf though lol https://www.youtube.com/watch?v=4lPLCwitPWY
02:17 PM Loetmichel: and CNC routers are ALWAYS to small
02:17 PM Loetmichel: you WILL outgrow even the 6040 pretty quick ;)
02:18 PM Loetmichel: gloops: maaan, that blue smoke... you should use a sharper bit and/or less RPM ;)
02:18 PM Loetmichel: hetii: i ran into size restrictions a few times...
02:19 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=16414&g2_imageViewsIndex=1
02:19 PM gloops: it was one of the first cuts i did with it, any tool to hand, just testing it, i only use 3mm bits for sheets now
02:19 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=16182&g2_imageViewsIndex=1
02:19 PM hetii: Loetmichel, interesting, I read that 6040 is less stiffer then 3040 at least in Z
02:19 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=17121&g2_imageViewsIndex=1
02:19 PM Loetmichel: :-)
02:20 PM Loetmichel: hetii: it is a bit less stiff in the gantry
02:20 PM gloops: take things a bit slower now https://www.youtube.com/watch?v=zE_AGP75en8
02:20 PM Loetmichel: but the long axis (gantry moving) is weak on the 3040 because of the unsupported rails
02:20 PM Loetmichel: wich is more of a problem
02:21 PM gloops: this gantry is about 60 kilos, 2 x 425 oz motors, a wooden gantry would fly with those steppers
02:21 PM Loetmichel: i can assure you that it is NOT a problem to mill alu with a 6040 though
02:24 PM hetii: That`s why I order linear guide.
02:24 PM hetii: So far I spend around 1000$ for motors+sppindle+vfd+linear guide kit
02:25 PM Loetmichel: for that price you would have gotten a complete CNC 6040
02:25 PM hetii: so at the end I suppose will pay less then 6040
02:25 PM Loetmichel: ... just saying ;)
02:26 PM hetii: but not with 2.2kw spindle :)

02:26 PM Loetmichel: they are cheap as fu** these days
02:27 PM gloops: https://www.ebay.co.uk/itm/New-6040-3-Axis-Desktop-CNC-Router-Engraver-Milling-Machine-Engraving-Drilling/232740909280?
02:27 PM Loetmichel: no, with 800W spindle, which is perfectly sufficient
02:27 PM Loetmichel: indeed, gloops
02:27 PM gloops: ahh to just unpack and connect up lol
02:28 PM Loetmichel: yes
02:28 PM gloops: instead of 2 months torture in the garage
02:28 PM Loetmichel: yes
02:28 PM hetii: hehe :)
02:28 PM Loetmichel: needs a few end/ref switches and a bit of tinkering/adlusting, but basically you can have it running on the same day as delivery
02:28 PM gloops: still, you dont learn anything that way
02:29 PM hetii: well. What I can say, i`m not sure if do It right but at least will try ;)
02:29 PM Loetmichel: oh you will ;)
02:29 PM Loetmichel: learn things i mean
02:29 PM Loetmichel: hetii: point i tried to make with my enclosures are that even the 6040 gets "to small" fast
02:29 PM Loetmichel: dont start with the 3040, its simply too small for a lot of things
02:32 PM hetii: ok will keep that in ming
02:32 PM hetii: *mind
02:33 PM * Loetmichel is trying to convince the boss to allow me to build one with a 2m by 1m travel so we can utilize full "small sheets" from the sheet metal dealer and dont have to pay for cuts
02:35 PM hetii: make sense for me :)
02:38 PM gloops: theres one thing, when i show people stuff i made, they say - yeah but you didnt really make it, the machine did
02:38 PM gloops: then i say yeah - but i made the machine as well
02:38 PM * Loetmichel is a bit careless sometimes... dont do things like that if you like your fingers: https://www.youtube.com/watch?v=1Ym4Y9HEm4s
02:38 PM Loetmichel: gloops: same here ;)
02:39 PM gloops: anyway got to go out bbl
02:42 PM hetii: hmm I just realize that should also add some very simple hardware based protection if my spindle will go outside allowed range
02:42 PM hetii: cause if software will freeze there will not be chance to stop it
02:58 PM gloops: the vfds are pretty good for that
03:09 PM hetii: time for me, thx for chat and see U soon :)
03:27 PM XXCoder: Loetmichel: even if you make cnc router arce sized? ;)
03:28 PM Loetmichel: arce???
03:28 PM XXCoder: yeah unit of farm land area, mispelled. acre heh
03:28 PM Loetmichel: acre!
03:28 PM Loetmichel: nope, that would be a bit big
03:29 PM XXCoder: engrave entire sides of building facades lol
03:30 PM Loetmichel: i once help make one that used crane rails and -beam in a 8m by 15m workshop though...
03:30 PM XXCoder: imange the challenges of building such a big machine. even if it would be rated for light engraving only.
03:30 PM Loetmichel: was fun.. not that accurate on the other hand ;)
03:32 PM Loetmichel: at that size it starts getting more useful to have the machine move on the surface of the workpiece than build a machine that can enclose the workpiece
03:32 PM XXCoder: cool :)
03:32 PM Loetmichel: you know, like an excavator with a chisel head
03:32 PM XXCoder: yeah theres small machines like that
03:33 PM XXCoder: theres one cnc spider that can cut unlimited area
03:33 PM XXCoder: dunno how accurate as it gets futher out of starting spot
03:34 PM XXCoder: LOL https://www.nbcnews.com/news/world/banksy-painting-shreds-itself-moments-after-being-sold-1-4-n917326
03:39 PM Loetmichel: XXCoder: i would have liked to see the face of the buyer...
03:39 PM XXCoder: yeah. lol
03:39 PM XXCoder: apparently it was sold but it had secret anti-auction stuff
03:39 PM jthornton: hay
03:41 PM XXCoder: it was olviously keyed to hammer noise
03:54 PM Loetmichel: or banksy was watching the acution and had a remote
04:10 PM Deejay: gn8
04:13 PM XXCoder: maybe that is the case
04:13 PM XXCoder: though not sure if cellular connection worked though there
04:15 PM XXCoder: there might be snow in arizona soon
04:15 PM XXCoder: dang
04:17 PM jthornton: we are cooling down mid week
04:23 PM robotustra: snow is not so cool actually
04:24 PM XXCoder: hot snow eh? heh
04:25 PM * Loetmichel wants an oven with pyrolysis setting... took me 2 hours with steel wool and NaOH foam to get it SOMEWHAT clean... my back is killing me...
04:26 PM jthornton: snow is a fair insulator
04:27 PM Loetmichel: jthornton: 60% air or so, and water isnt that good a thermal conductor either... there is a reason the innuit build houses out of that white stuff
04:27 PM XXCoder: heh yeah it takes so much energy to boil water
04:27 PM jthornton: I know I used to build igloo's when I was young
04:28 PM Loetmichel: XXCoder: thats thermal energy storage, not thermal conductance
04:30 PM XXCoder: yeah]
06:02 PM XXCoder: LOL https://www.youtube.com/watch?v=0gQI9SCAvtQ love it
06:09 PM MarcelineVQ: the thing about small safes is you can stick them in a bandsaw :>
06:09 PM XXCoder: and probably cut the thing in it yeah
06:09 PM XXCoder: if I was being evil about it I could make 4 of em and 3 of em has sealed cyadite inside
06:09 PM MarcelineVQ: That's a pretty metal ending though
06:10 PM XXCoder: yeah
06:10 PM MarcelineVQ: the video has some metal music playing during it as well fyi
06:10 PM MarcelineVQ: during the whole thing I​ mean
06:10 PM XXCoder: cool
06:11 PM XXCoder: interesting https://www.youtube.com/watch?v=5W8O4oVGL00
06:11 PM XXCoder: cermic endmill
06:11 PM MarcelineVQ: ceramic is getting a lot of attention recently it seems, dunno if that's reflecting industry or there's just more vids about it now
06:12 PM XXCoder: dunno, previously there was only inserts. entire endmill is new
06:13 PM XXCoder: dang
06:13 PM MarcelineVQ: wonder what metal that is
06:13 PM XXCoder: metal part is all chipped the fuck out
06:14 PM XXCoder: thats very heavy abuse
06:14 PM MarcelineVQ: the first comment I see here is pretty great "No chips just lava"
06:14 PM XXCoder: thats great for roughing
06:14 PM XXCoder: then can use regular ones for finish and last much longer
06:15 PM MarcelineVQ: I'd be concerned about heat given just this video to go on, not that one should go on a video, and especially just one video
06:15 PM MarcelineVQ: Overall it doesn't help that ceramic doesn't mean much as a descriptive word, it only means the binder involved in making it isn't carbon
06:15 PM XXCoder: actually ceramic loves heat
06:15 PM XXCoder: hotter the stronger
06:15 PM MarcelineVQ: It's the part I'd worry about heating :>
06:16 PM MarcelineVQ: Carbide isn't any more descriptive though I guess, since all it means is that binder is carbon hehe
06:16 PM XXCoder: yeah lol
06:17 PM Tom_L: https://www.sandvik.coromant.com/en-us/knowledge/materials/workpiece_materials/iso_s_hrsa_titanium/pages/default.aspx
06:17 PM MarcelineVQ: It should ring alarm bells that this is official advertising however, given the cutter's state at the end
06:18 PM XXCoder: it seemed to be very very heavy abuse
06:18 PM XXCoder: going way too fast on very hard metal
06:18 PM MarcelineVQ: Which metal was it?
06:18 PM Tom_L: ^^
06:18 PM XXCoder: its certainly not alum but not too sure.
06:19 PM XXCoder: "nickel based alloys"
06:19 PM gregcnc: ceramic endmills aren't that new
06:19 PM XXCoder: like intcel I guess
06:19 PM XXCoder: really? it was first I heard of
06:19 PM MarcelineVQ: it is inconel appearantly, Inco 718
06:19 PM MarcelineVQ: that is fast for inco <_<
06:20 PM gregcnc: kennametal has been making them for years
06:20 PM MarcelineVQ: Not that we haven't seen carbide do that speed, but it's comparable at least
06:21 PM MarcelineVQ: And explains the chipping
06:21 PM XXCoder: inconel sucks
06:22 PM XXCoder: I engrave lots of disks of inconel and tool life is brief, around 40 to 60 parts
06:22 PM XXCoder: stainless steel disks I could run over 1000 just fine
06:22 PM MarcelineVQ: This might be okay with flood coolant, the dust would be awful otherwise
06:23 PM XXCoder: cermtic tools would explode when hit with coolant
06:23 PM gregcnc: right ceramic runs dry
06:23 PM MarcelineVQ: Is that the case currently? They used to say that about carbide
06:23 PM MarcelineVQ: dang
06:23 PM MarcelineVQ: that's terrible, the dust that would come off this part...
06:24 PM XXCoder: wouldnt be worse than fiberglass lol
06:25 PM MarcelineVQ: fiberglass shops are scary :(
06:25 PM XXCoder: thankfully work dont run lot of em
06:25 PM XXCoder: just 3 varations of one part
06:25 PM MarcelineVQ: Can't even stand the resin vapor smell near production shops, lets alone imagine the horror of shops where it's cut
06:26 PM XXCoder: it runs on only machine that can run em as fiberglass "clay" would kill chip conveyers
06:26 PM gregcnc: 2013 https://www.youtube.com/watch?v=U3l4tZd5KbE
06:29 PM gregcnc: i was thinking of this video, but it's an insert mill https://youtu.be/c1K5QjR3hyU
06:30 PM XXCoder: i love that video. and yeah one I was talking about when i said inserts. funny how it goes eh
06:30 PM XXCoder: gonna love fireworks
06:36 PM gregcnc: that sandvik ceramic tipped end mill looks like a good idea. brazed ceramic?
07:14 PM gregcnc: what's the LED light people are using in machines?
07:15 PM XXCoder: the led light status stack?
07:16 PM Rab: I have some of these: https://www.ebay.com/itm/302448222595
07:16 PM Rab: Or maybe it's a 30-LED version.
07:17 PM gregcnc: the lights guys are putting in their mill enclosures vs paying 500-1000USD for factory lights
07:18 PM gregcnc: something like this i guess
07:18 PM gregcnc: https://parts.haascnc.com/haasparts/en/USD/Find-Replacement-Parts/Enclosure/Lighting/Work-Light/WORKLIGHT%2C-LED%2C-20W-MAGNETIC-MOUNT-W-C13-ADAPTER/p/93-2378
07:20 PM gregcnc: ah http://a.co/d/ia4Pkt4
07:22 PM gregcnc: that looks big

07:24 PM Roguish: 7D
08:55 PM jthornton: hey
08:57 PM Tom_L: what's up?
08:57 PM jthornton: just got back from dinner
08:58 PM Tom_L: alot cooler here today
08:58 PM Tom_L: wind from the N
08:59 PM jthornton: pretty warm here
08:59 PM Tom_L: mid to low 50's
09:02 PM jdh: 92f
09:05 PM jthornton: ready to head home for sure
09:05 PM jdh: where?
09:07 PM jthornton: we are in Murray Ky
09:07 PM Tom_L: ahh still?
09:07 PM Tom_L: figured you would have a 'mobile' nick
09:07 PM jthornton: yea, head home in the morning
09:08 PM jthornton: dang Spyder is making a squealing sound from somewhere
09:09 PM jthornton: ah yea the mobile link is not registered
09:09 PM Tom_L: hope you don't get stuck on a bridge somewhere like before :(
09:10 PM jthornton: yea that day sucked for sure...
09:11 PM jthornton: I have to cross two bridges to get home the Ohio and Mississippi bridges both very very old bridges
09:18 PM XXCoder: ow
09:21 PM jthornton: it will be the fourth time we cross them this weekend lol
