04:57 AM XXCoder: pink_vampire: hey
04:58 AM XXCoder: whats that white stuff? syrofoam?>
05:09 AM jthornton: morning
05:10 AM XXCoder: hey jt
05:33 AM Tom_L: morning
05:33 AM XXCoder: overtime today was so boring
05:33 AM XXCoder: lots prep parts
05:35 AM Tom_L: do you always run the same machine?
05:36 AM XXCoder: nah
05:36 AM XXCoder: though for some reason i always run a61 in late spring/summer
05:36 AM XXCoder: theres only 3 mill machines I never ran.
05:37 AM XXCoder: lathes is opposite, I only ran 3 out of all those lathes.
08:35 AM gregcnc: following up my screwup last night
08:35 AM gregcnc: It wasn't estop, but ESC to stop the program
08:36 AM gregcnc: the first two holes of 14 were drilled in the correct place, third was in the wrong place
08:36 AM gregcnc: afterward G54 is wrong
08:43 AM jthornton: which version and which gui?

11:48 AM _unreal_: OMG i wish my new motor controllers would just arrive
11:48 AM _unreal_: I have no idea when it will arrive
11:51 AM CaptHindsight: no tracking info?
11:53 AM _unreal_: nope
11:54 AM _unreal_: Tracking Information
11:54 AM _unreal_: Provider Tracking Number Date
11:54 AM _unreal_: USPS May 14, 2019 Track
11:54 AM _unreal_: I click on the track link and it just brings me to a page for entering a tracking number
11:55 AM CaptHindsight: clever, very clever
11:56 AM pink_vampire: hi
11:56 AM gambakufu: Snapmaker 2.0’s linear module has been upgraded for easy maintenance. The leadscrew, driver chip and precision parts are completely enclosed in the aluminum alloys housings.
11:57 AM CaptHindsight: leadscrew thanks, just scrolling through was painful enough
01:20 PM pink_vampire: XXCoder: it is foam pvc
02:23 PM phipli: Did anyone in the UK here buy an Atomic Pi?

02:32 PM pink_vampire: I have few eeepc
04:18 PM ziper: can you hand cut aluminum with a router or is it too difficult to get the feed right
04:22 PM SpeedEvil: You can in general use all wood tools just fine for aluminium until they grab
04:22 PM Deejay: gn8
04:23 PM SpeedEvil: A handheld router can work, but you need to pay even more careful attention to direction of cut
04:28 PM enleth: ziper: actually, router bits with a follower bearing (to positively limit tool engagement) will cut steel in a handheld router if you take it slow with light passes
04:30 PM enleth: so you can get nice rounded edges on a waterjet cut plate, for example
04:30 PM enleth: I'm pretty sure Tom Lipton had a video proving this
04:34 PM SpeedEvil: and yes
04:34 PM SpeedEvil: at slow speed, router guided bits are great
04:35 PM ziper: so as long as you push it, no problem? my router is old though, and runs at a billion rpm
04:35 PM SpeedEvil: Aluminium can be cut at high speed
04:37 PM enleth: ziper: you won't know until you try but your chances are quite high
04:41 PM jthornton: some of the folks on the forum make no sense at all like pi7i96 and k-1, I wonder what planet they are from?
04:43 PM SpeedEvil: It also depends on your hopes for the cut.
04:43 PM SpeedEvil: You can cut sheet steel with a standard wood blade on a wood circular saw.
04:43 PM SpeedEvil: Just not for long.
04:46 PM _unreal_: my hobbycnc kit arived
04:48 PM XXCoder: ziper: billion rpm? very small radius tool
04:49 PM jthornton: morning XXCoder
04:49 PM SpeedEvil: and yeah - teeny tool can work until you break it off
04:49 PM XXCoder: hey
04:49 PM SpeedEvil: due to high stick-out
05:16 PM pink_vampire: hi
05:18 PM pink_vampire: https://i.imgur.com/dru5iHt.png
05:19 PM pink_vampire: chips all over
05:21 PM andypugh: As your message came in I was delving under my jumper to find the lump of steel swarf that just became evident...
05:25 PM pink_vampire: this is why i love pvc foam
05:39 PM andypugh: I am going to make a YouTube video of my current project. I have something for the out-take section at the end….
05:39 PM andypugh: https://youtu.be/hD0hmRByqoo
05:40 PM pink_vampire: multifix!!
05:41 PM pink_vampire: the fail look amazing
05:42 PM andypugh: I think my reaction was surprisingly restrained.
05:46 PM pink_vampire: what was the stock?
05:46 PM pink_vampire: it look like it split
05:48 PM * jthornton prepares a sodium hypochlorite cocktail for the bird bath
05:49 PM pink_vampire: ????????
05:49 PM jthornton: bleach
05:49 PM pink_vampire: why?
05:50 PM jthornton: clean the algae out
05:51 PM pink_vampire: algae ? on the bird?
05:51 PM jthornton: in the bird bath the chickens use to get drinking water from and so do the birds
05:52 PM jthornton: not bathing a bird, cleaning the bird bath out
05:52 PM pink_vampire: ok ok i see
05:53 PM jthornton: have to do that about once a month in the summer, let it sit all night then flush in the morning before letting the hens out
05:55 PM pink_vampire: I like to have some algae in my fish tank
05:56 PM pink_vampire: the shrimp like to eat it
05:57 PM jthornton: send some shrimp over to me to clean the bird bath but they better be quick or the chickens will eat them lol
06:02 PM Tom_L: andypugh, http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/A3/Mold7.jpg
06:02 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/A3/Mold11.jpg
06:03 PM jthornton: casting some aluminum?
06:03 PM enleth: robot finally mounted on a support frame and ready to be used
06:04 PM enleth: we streamed the whole thing, recording is at https://youtu.be/atvtm4H-jF8?t=2079 if anyone's curious what it takes to mount a 1.4t robot (interesting stuff starts at the timestamp in the link)
06:06 PM enleth: this is a custom frame I designed to fit in a specific spot in the shop, it's somewhat weird-shaped to allow a pallet jack to pick it up with the robot bolted on
06:10 PM Tom_L: jthornton, yeah maybe
06:11 PM jthornton: you been watching some myfordboy videos?
06:14 PM Tom_L: no
06:15 PM Tom_L: dude up in canada wanted me to make him a mold
06:16 PM Tom_L: it's about as easy to machine them but his mill is tiny
06:17 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/rue/Can_Holder/A3/A3_1.jpg
06:37 PM _unreal_: There I just finished soldering together my hobbycnc board
06:37 PM _unreal_: few steps left to go to "set it up" and I discovered the Heat sink that was provided. has pilot knotches ONLY. not drilled at tapped at all WTF..
06:38 PM _unreal_: and it does not list the screw size so I'm trying to figure out what size to drill/tap it to
06:38 PM Tom_L: jthornton, do you know how much shrinkage aluminum has when molding it?
06:39 PM Jymmm: molding? or casting?
06:39 PM Tom_L: casting
06:39 PM _unreal_: ! found it 4-40 screws
06:39 PM _unreal_: ok heading out to the store to get a 4-40 tap/drillbit
06:46 PM andypugh: Tom_L: You could have got away with having the vent on one side only, I suspect.
06:47 PM Tom_L: i wondered if it would drain the mold if i didn't take it to the top
06:47 PM andypugh: pink_vampire: The stock was 6 carefully machined pieces of tool steel, several hours of machinign to get them all to fit together like that.
06:47 PM Tom_L: ahh i see what you mean..
06:47 PM andypugh: Tom_L: Oh, it has to go all the way to the top, but a groove in one mould-half only would have worked.
06:48 PM Tom_L: yeah
06:48 PM Tom_L: i just mirrored the code so it wasn't any extra work really
06:48 PM Tom_L: just a couple min machine time
06:53 PM pink_vampire: andypugh: what are you trying to build?
06:53 PM andypugh: It’s an expanding swageing thing
06:53 PM Tom_L: starting over?
06:54 PM andypugh: Well, when I was machining the cheese-wedges yesterday I thought it wise to make 12 rather than 6. And was proved right.
06:56 PM andypugh: https://photos.app.goo.gl/EB3tb45V8LPihtWn6
06:56 PM andypugh: Just need to machine the hexagon now.
06:57 PM andypugh: (Which is where the firsrt one went wrong. This is now my third attempt.
07:15 PM pink_vampire: andypugh: you need a swiss machine
07:16 PM andypugh: I am not sure it would help a lot in this case.
07:17 PM andypugh: The trick is actually to use my special tailstock centre: https://photos.app.goo.gl/7yj567ZDjaVs3DUu9
07:17 PM andypugh: Which can hold the ends together.
07:41 PM pink_vampire: just cut each section on a 4th axis
09:12 PM CaptHindsight: https://www.wolfautomation.com/light-tower-o60mm-led-npn-24vdc-rygb/
09:13 PM CaptHindsight: Red means Stop, Yellow is Caution machine nearby...
09:13 PM CaptHindsight: Green means you are free to use the machine
09:14 PM CaptHindsight: Blue is machine police, pull machine to side of room
09:15 PM XXCoder: unable to connect to machine
09:15 PM XXCoder: er server
09:16 PM CaptHindsight: BLUE: External help request, where an operator might be requesting raw materials, scheduling or maintenance personnel assistance
09:17 PM CaptHindsight: makes no sense, blue is feeling down or sad
09:24 PM XXCoder: me sad need help
09:28 PM XXCoder: wolfautomation site is down to me
09:29 PM CaptHindsight: https://surplus.motionconstrained.com/shop/lasers/controllaser-elite-50w-laser-welder-1064-nm-aerotech-5-axis-motion-control-used/
09:30 PM XXCoder: 5 axis welder interesting
09:32 PM pink_vampire: blue is operator needed
09:32 PM pink_vampire: I have a stack light on my machine
09:32 PM XXCoder: none of machines at work has blue
09:32 PM pink_vampire: it is a grate addition
09:32 PM pink_vampire: the buzzer is also nice
09:33 PM pink_vampire: the probe and the finish program connect to it
09:35 PM CaptHindsight: pink lamp: possible danger, watch your heart
09:35 PM CaptHindsight: purple lamp: things might get funky
10:18 PM pink_vampire: I need better probe
10:19 PM XXCoder: make one
10:19 PM XXCoder: nahh pink lamp: pink is coming.
10:21 PM pink_vampire: I need rgb stack light that tell the time to finish
10:21 PM pink_vampire: like a bar graph
10:21 PM XXCoder: how about a light bar that pops lights as percent gets closer to 100%
10:22 PM XXCoder: just need a led bar that has addressable leds
10:22 PM pink_vampire: there is a product like that
10:22 PM XXCoder: not surpised.
10:23 PM XXCoder: do you plan to do it from line numbers or calculated from how long?
10:23 PM XXCoder: both has pros and cons
10:24 PM pink_vampire: no, I'm happy with my current stack light
10:25 PM pink_vampire: http://www.prweb.com/releases/2013/4/prweb10606959.htm
10:28 PM pink_vampire: https://i.imgur.com/TV5S5mz.png I didn't crash it
10:28 PM XXCoder: probe rod that short?
10:29 PM pink_vampire: https://i.imgur.com/mM0rgVY.png
10:29 PM pink_vampire: picture from the front
10:29 PM pink_vampire: dream job - operating a cmm machine
10:30 PM XXCoder: oh looked ike it was very short from other side lol
10:31 PM pink_vampire: if you move the probe 1/8" to the left - it is gone
10:38 PM pink_vampire: I took a picture of the setup
10:39 PM pink_vampire: I need to cut a radius on the plastic block right in the middle, and offset it 1" from the edge ad the back
10:43 PM pink_vampire: so this is what I came up with, the fixed jaw was mount on the back side, and there is a parallel between the jaw to the plastic block, by closing the vise, I make sure the plastic block is tight against the back, and 2 additional clamps press it down. to machine the radius i just open the vise
10:43 PM pink_vampire: https://i.imgur.com/onneqoH.png
10:44 PM XXCoder: not bad
10:44 PM pink_vampire: I need to make 4 of those
10:45 PM XXCoder: i guess to grip something round?>
10:45 PM pink_vampire: the spacing between to holes is the T slot in the table
10:47 PM pink_vampire: https://nh.craigslist.org/tls/d/mont-vernon-table-top-portable-electric/6887645180.html
10:47 PM pink_vampire: "Portable"
10:47 PM XXCoder: lol
10:50 PM Rab: I mean, if you had a choice between that and lugging around a pedestal grinder...
10:50 PM pink_vampire: LOL
10:51 PM XXCoder: but modern grinder is little more than motor and 2 wheels
10:51 PM XXCoder: its actually more portable.
10:53 PM pink_vampire: what about cordless dremel
11:10 PM Tom_L: may as well never been invented
11:14 PM gloops: whats the plastic shape for?
11:15 PM pink_vampire: clamping test
11:15 PM gloops: looks like bearing caps
11:18 PM gloops: i bought a similar grinder to the one in the pics, only difference was some old guy had made a steel bath for the grinding wheel, obviously with rudimentary tools and skills lol, i took the motor off for something else, but i couldnt throw the rest away it was a work of art
