#garfield Calendar
12:00 AM rue_shop2: you were just using magazine pages for a while
12:16 AM rifraf: there are so many plugins to use with the hosting, am wasting money not spending some time to work it out
12:18 AM rue_shop2: see thats SO much easier
12:20 AM rifraf: https://www.desire3d.com/images/public/dualtoolpost1.jpg
12:20 AM rifraf: https://www.desire3d.com/images/public/dualtoolpost.jpg
12:22 AM rifraf: need to weld the 2 bits into 1 after tapping new threads
12:24 AM rifraf: is amazing how larger posrt still uses all the same tools, i should see if the one on lathe can be upgraded
12:24 AM rifraf: just holds the tools 4X better
12:29 AM rifraf: rue_shop2 were the pics ok? ad free?
12:29 AM rue_shop2: sweet, I can just open them!
12:29 AM rue_shop2: I should get one of those quickposts
12:29 AM rue_shop2: we have one at work
12:29 AM rifraf: they are the best
12:29 AM rue_shop2: its nice to not need random shims
12:30 AM rifraf: yep, one of many reasons
12:31 AM rifraf: dual setup work a test?
12:31 AM rifraf: \if the small one can do parting off would be awesome
12:32 AM rifraf: but it was hard work before
12:32 AM rifraf: can add a few gussets, but will test weld up in the morning
12:33 AM rifraf: i think with the first tool set back more than the radius of part beiug turned will make it handy
12:42 AM rue_shop2: I look forward to finding a job with multiple tools on the cnc I can have it make things in the spindle
12:42 AM rue_shop2: its not co-ordinated tho, so no threading
12:42 AM rue_shop2: synchronized
12:42 AM rifraf: make spinning tops
12:43 AM rifraf: very good test of machine repeatability
12:43 AM rifraf: mine still has long way to go
12:50 AM rue_mohr: going to make a nice compact tilt and pan for camera first
12:50 AM rue_mohr: then put it on a remote controlled robot
12:51 AM rue_mohr: and hook it up to the FPV headset I got me
12:51 AM rue_mohr: and run around the house pondering what life as a robot will be like
12:52 AM rue_mohr: then ponder how to put a motion tracker on the goggles so I dont have to manually operate the tilt and pan
12:52 AM rifraf: http://www.roboreprap.com/robotics/motion/micro_tracker.htm
12:52 AM rue_mohr: no
12:52 AM rue_mohr: I mean head tracking
12:53 AM rue_mohr: so when I tilt and pan my head, the camera moves with me
12:53 AM rifraf: http://www.roboreprap.com/robotics/motion/motion_tracker.htm
12:53 AM rifraf: yep, these were used for foxys eyes
12:53 AM rue_mohr: yea
12:53 AM rue_mohr: but I have a FPV headset
12:53 AM rifraf: but yes, i have some FPV stuff here
12:53 AM rifraf: never used after crashing quadcopter a few times
12:53 AM rue_mohr: I want to put a gyro on it
12:54 AM rue_mohr: and have it operate the tilt and pan
12:54 AM rifraf: should be easy enough\
12:55 AM rifraf: https://youtu.be/AalBO4x4K5s
12:58 AM rifraf: bit rough but proof of concept
01:00 AM rifraf: my my the things i have spent too many hours making https://www.youtube.com/watch?v=IbVwU4Qmx30
01:02 AM rifraf: every bit of gripper and arms designed and cnc cut
01:02 AM rue_mohr: its good work rif
01:02 AM rue_mohr: esp visible to me as I'm struggling to get myself to do anything
01:03 AM rue_mohr: I wonder if you ever saw all the arms I was making
01:03 AM rue_mohr: I was getting on quite a roll
01:03 AM rifraf: yep would have seen many
01:03 AM rifraf: i have alot here as well to finish
01:04 AM rifraf: scara arms and such
01:04 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/arm9/p1060859.jpg
01:04 AM rifraf: decent sized ones
01:04 AM rue_mohr: nothing cantalivered off servos
01:04 AM rue_mohr: I built 4 or 5 of them
01:04 AM rifraf: yep looks pretty well made
01:05 AM rue_mohr: https://www.youtube.com/watch?v=TNXW3uTktHc
01:05 AM rue_mohr: https://www.youtube.com/watch?v=j4uz_yha9uI
01:05 AM rue_mohr: https://www.youtube.com/watch?v=slxOrCXxXOg
01:06 AM rue_mohr: https://www.youtube.com/watch?v=3N7DNfg4p9I
01:07 AM rue_mohr: its sort of surreal when you hook them all up in parallel and move the trainer around
01:07 AM rue_mohr: its like having a private army
01:07 AM rue_mohr: kinda spooky
01:08 AM rue_mohr: they just operate on serial using a modded ssc8 protocol
01:08 AM rue_mohr: (10 bit positioning and some other goodies)
01:10 AM rue_mohr: hmm, perspex is hard to cut
01:10 AM rue_mohr: tonnes of heat
01:12 AM rifraf: so very cool rue, thouroughly enjoyed watch them all
01:20 AM rue_shop2: :] I had fun while you were out playing
01:20 AM rue_shop2: I know you did too
01:21 AM rue_shop2: I hope thebear has found a happy place
01:21 AM rifraf: yeah
01:21 AM rue_shop2: I think his body was failing him bad tho
01:21 AM rue_shop2: maybe he got his motorbike working
01:22 AM rue_shop2: produced an amazing song
01:22 AM rue_shop2: or found a more lewd door key
01:23 AM rue_shop2: his bunk idea didn't work for me out here
01:23 AM rue_shop2: I hit my head on the ceiling every morning
01:27 AM rue_shop2: http://ruemohr.org/%7Eircjunk/house/dscn7993.jpg
01:28 AM rifraf: not enough room at all
01:28 AM rue_shop2: nope
01:28 AM rue_shop2: bear had like a 3.5m cieling
01:33 AM rue_shop2: heh, it might be fun to make a little machine that spins gears and uses an audio feeler to count the teeth
10:01 AM rue_mohr: damnit, I'm going looney
10:01 AM rue_mohr: I got nobody to talk to anymore
10:03 AM rue_mohr: I still dont get why I need anyone to talk to tho
10:03 AM rue_mohr: as a kid, I didn't have anyone
10:03 AM rue_mohr: when did this all change
10:05 AM rue_mohr: I wonder if I been poisoned by hope
10:06 AM rue_mohr: I know now that all the directions I was going were right
10:06 AM rue_mohr: I should have confidence that still holds true
11:36 AM Tom_L: talk
11:36 AM Tom_L: snap outta your gloom and build stuff
11:49 AM rue_mohr: cant concentrate
11:50 AM rue_mohr: do you think the military would support an attack on canada?
11:51 AM rue_mohr: I think they would do what they were told to
12:24 PM Tom_L: i kinda doubt that would happen
01:06 PM rue_mohr: would you kinda doubt most of what rump has done would happen?
01:06 PM rue_mohr: chatgpt was funny
01:06 PM rue_mohr: "what would happen if the us president did 'this'"
01:07 PM rue_mohr: "that would be bad, that would never happen"
01:07 PM rue_mohr: "it happened"
01:07 PM rue_mohr: "oh, I'm sure its fine, its not that bad"
01:12 PM rue_shop2: I'm cold
01:15 PM rue_shop2: I'm trying to make this tilt and pan unit nice and compact, its being awkward
01:27 PM Tom_L: no i expected him to come with a vengance
01:33 PM rue_shop2: well he's laying waste inside and out
01:34 PM Tom_L: i am glad he's flushin the freeloaders out
01:34 PM Tom_L: i don't really keep up on the news
01:34 PM Tom_L: it's generally bad
01:35 PM rue_shop2: yea, dont agree with the break-then-fix apposed to the replace-with-working
01:35 PM Tom_L: https://www.google.com/maps/@24.7822082,-90.1951675,5.58z?entry=ttu&g_ep=EgoyMDI1MDIxMi4wIKXMDSoASAFQAw%3D%3D
01:35 PM Tom_L: thought that was kinda funny
01:36 PM rue_shop2: yea, I dont know if he's had google rename anywhere else
01:38 PM Tom_L: lots of the globe has been renamed since i've been alive
01:39 PM rue_shop2: but by one lunitic or by a comitee of them?
01:43 PM rue_shop2: wtf, with anthem lyrics
01:44 PM rue_shop2: google pulls up garbage for both our countries
01:45 PM rue_shop2: wtf...
01:45 PM rue_shop2: ugh
02:38 PM rue_mohr: I remember doing a tilt and pan laser, I'm not sure where it went
02:53 PM rue_mohr: ok, my cat decided to curl up in the kitchen cuppboard and not talk to me
02:53 PM rue_mohr: this probably isn't good
03:13 PM rue_shop2: oz network didn't get any better
03:13 PM rue_shop2: still tryin to work out how to feed the whole country off 1 twisted pair
04:41 PM rue_shop2: I need to fix a few 3d printers
04:51 PM Tom_L: how many do you have?
04:52 PM Tom_L: felt kinda good to dive into some code yesterday after quite a lapse
04:53 PM Tom_L: learned some more about polar coordinates
05:04 PM rue_shop2: 5
05:26 PM rifraf: evenin all
05:26 PM rifraf: am filing here, then a bit of weldin
05:36 PM rue_mohr: one printer needs a new controller, there is some sort of intermittent fault between 5 and 12V
05:36 PM rue_mohr: another one, the laptop that runs it needs a new hard drive (working on that now)
05:37 PM rue_mohr: 8/40G copied
05:39 PM rue_mohr: or the issue is the laptop, hopefully not
06:19 PM rifraf: ok let it cool down a bit, clean up and is done
06:47 PM rue_shop2: well crap
06:47 PM rue_shop2: the slicer program was broken so I told the machine to just do a whole upgrade and it deleted its bin utils and now cant do anything
06:47 PM rue_shop2: so I have to take the drive out and start again
07:00 PM rifraf: its always easier to start again with 3d printers
07:00 PM rifraf: too much changes, and you miss out trying to keep old crap working
07:01 PM rifraf: even though most of mine still have ramps 1.4 boards, they just work
07:05 PM rifraf: ok its made, ready to mount and test some while later https://desire3d.com/images/public/dualtoolpost2.jpg https://desire3d.com/images/public/dualtoolpost3.jpg
07:08 PM rifraf: 4.8kg with the tools and handle
07:08 PM rifraf: this larger post gonna make much more stability i am sure, hope repeatability is as good
07:11 PM rue_shop2: huh the problem could be toms stl
07:11 PM rue_shop2: not sure how
07:15 PM rue_shop2: yea, its not corrupt, toms stl is broken somehow
07:17 PM rifraf: what a trouble maker he is, time to get out meshmixer
07:18 PM rifraf: maybe meshlab now
07:19 PM rifraf: what are you trying to make
07:19 PM rue_shop2: it seems I have a newer file
07:19 PM rue_shop2: I'll try it in a bit
07:20 PM rue_shop2: I'm trying to print a 2nd jig for slotting parts for the new cnc
07:20 PM rue_shop2: it would go lots faster
07:20 PM rue_shop2: but the old machine is working away at a steady turtles pace (as it does)
07:22 PM rifraf: did you see tool post holder?
07:22 PM rue_shop2: oh nice!
07:24 PM rue_shop2: well, I got the hard drive replaced anyhow
07:24 PM rue_shop2: I cant believe apt removed the utils it needed to operate
07:24 PM rue_shop2: wtf
07:25 PM rue_shop2: I'll have to fight with an upgrade at some point
07:25 PM rifraf: yep, this is worth a test, can see i may have to forget about the inline position for small toolpost and leav it set back, because might be interference with chuck and using the large one
07:25 PM rifraf: but i had to do it cause it was buggin me
07:25 PM rue_shop2: might also be worth pondering a front/back tool
07:25 PM rifraf: tomorroe shipment of parts arrive to continue the 5C chuck project
07:26 PM rue_shop2: I go and try to get a wheel off a scooter for an elderly chap
07:26 PM rue_shop2: we already broke one of my wrenches on it
07:27 PM rifraf: wow, good canadian steel was it?\
07:27 PM rue_shop2: hah, no way
07:27 PM rue_shop2: but I'v never sheered the drive off a socket wrench before
07:27 PM rue_shop2: took me standing on it with a 0.5m cheater bar
07:27 PM rifraf: nope, thats a new one
07:28 PM rue_shop2: *plink*
07:28 PM rue_shop2: twisted it right off
07:28 PM rifraf: wd40 and some heat after a day
07:28 PM rue_shop2: I have an industrial impact wrench
07:28 PM rue_shop2: it will either take the nut off in 30 seconds or snap the axle
07:28 PM rifraf: yep
07:29 PM rue_shop2: every used autobody filler?
07:29 PM rifraf: yes
07:29 PM rue_shop2: crap, i was supposed to buy sanding sponges today
07:31 PM rifraf: lucky its only 11am, off you go to bunnings or equivalent
07:41 PM rue_shop2: the only store here I can get them from is closed tomorrow
07:41 PM * rifraf hands rue the tequila bottle
07:42 PM rifraf: we can just worry about tit the next day
07:42 PM * rue_shop2 passes it along to sam
07:42 PM rue_shop2: I have next week off
07:42 PM rifraf: me too
07:42 PM rue_shop2: but mon is a holiday, so I have to wait till tues
07:43 PM rifraf: mon is paid holiday for me too, lovin it
07:43 PM rifraf: reallity and no money start tuesday
07:45 PM rifraf: ok we need a test jig to test cylinders and slipring, not gonna drill and mount holes in headstock block just yet
07:46 PM rifraf: a few 8mm pins same distance apart as the arm mounts, to see how things move in 2 d
07:48 PM rifraf: rue do you use drill press often?
07:50 PM rifraf: today i drilled a hole with vice at 90° to get a hole in this large 150x50mm angle, worked well
07:50 PM rifraf: you need an electrovice
07:52 PM rifraf: tool height on this new tool post should not need height adjustment, seems to do entire range of old one plus extra
07:56 PM rue_mohr: I do use a drillpress quite a bit
07:57 PM rifraf: then you could do with an electromagnetic vice, a foot pedal operated one
08:00 PM rue_mohr: mm
08:00 PM rue_mohr: maybe a flatter one
08:01 PM rifraf: is less than 40mm thick
08:01 PM Tom_L: what stl?
08:01 PM rifraf: most drill press vices around the same
08:01 PM rue_mohr: the A12 holder jig, looks like I have the wrong version filed in a convienient place
08:02 PM Tom_L: dunno if i still have it or not
08:02 PM rue_mohr: I'll try the latest vesion, I'm sure it'll be fine
08:04 PM Tom_L: don't see any stl files in that folder
08:04 PM rue_mohr: I have newer files
08:04 PM rue_mohr: looks like I'd grabbed the wrong one
08:05 PM Tom_L: nor in the solidworks folder
08:06 PM rue_mohr: https://www.aliexpress.com/item/1005007688988702.html
08:06 PM rue_mohr: huh $9
08:07 PM rue_mohr: not sure how often I could use it tho
08:07 PM Tom_L: ever find your docs?
08:13 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/Mill_Steel/Drillpress.jpg
08:13 PM Tom_L: rifraf, had the drill press clamped to the table so i could reach what needed a hole
08:20 PM rue_shop2: no I'm not looking anymore, it just upsets me
08:28 PM rifraf: wow rue, certainly looks the part and price is right
08:29 PM rifraf: i reckon this unit would lift far more than 180kg
08:29 PM rifraf: but thats way more than you typically need, you need twice that force you normally use with your hand waiting for it to rip your fingers off
08:30 PM rue_shop2: lots of the stuff I do is plastic and aluminum
08:30 PM rifraf: obviously after M12 / 1/2" force increase quite a bit
08:30 PM rifraf: yes, an issue
08:31 PM rifraf: you need to have a few mounting points inserted inter the vice, to secure your normal plactic clamp
08:31 PM rifraf: a few nuts or nuts serts etc
08:32 PM rifraf: i seem to be more stell these days
08:32 PM rifraf: once you can work with it far cheaper than aluminium or even plastics
08:33 PM rifraf: and being able to glue it together is neat, was happy with the penatration on my welds to the 10 and 12mm mount plates today
08:33 PM rifraf: the tacks were nice and solid
08:33 PM rifraf: a few bits where i could have angled better or used a few more amps
08:34 PM rifraf: but hey, i am just the welding inspector, i can't do actually the job like the real welders
08:34 PM rifraf: but sure have improved after looking at them all day
08:35 PM rifraf: ok time to mount this new contraption, you guys are too quiet
08:52 PM rue_shop2: sorry, having issues
08:57 PM rue_mohr: callout from work
08:57 PM rue_mohr: go fix toilet
09:04 PM rue_shop2: rifraf, I think some of the stepper driver baords, sometimes have a 12V-5V short develop
09:26 PM rifraf: i guess it depends on your required voltage
09:26 PM rifraf: what steppers are your useing? i have some micro ones here, 8mm od, and about 12mm long steppers
09:27 PM rifraf: they are smaller than most micro quad motors
09:27 PM rifraf: and one of the things not thrown away
09:27 PM rifraf: because rue might need it sometime
09:30 PM rifraf: the robotics chat seems a few heatbeats short of life these days rue. what happened? no one makes shit anymore?
09:30 PM rifraf: or AI tells em all they need to know to do the same things as one another?
09:43 PM rifraf: when smokes still had writtin on em http://www.roboreprap.com/robotics/unknown/no_ac1.jpg
11:07 PM rue_shop2: foxy
11:07 PM rue_shop2: rifraf, A4892 or whatever
