01:26 AM IchGucksLive: morning
01:28 AM IchGucksLive: what a mess in the senat
01:28 AM IchGucksLive: so Ocare still up as it has been offerd to ben canceld first
02:01 AM Crom: oh that reminds me... I need to make a Tnut for a friends lathe. 1.41" square, 0.299 cross bar, 0.88" center 0.625" tall
02:02 AM Crom: I have a piece of 1" cold rolled
02:03 AM Crom: guess I'll put a #7 through the middle for a starter hole
02:03 AM archivist: you could anneal it
02:32 AM Deejay: moin
05:20 AM jthornton: morning
05:22 AM XXCoder: hey
05:22 AM XXCoder: man haas is bit fucked up sometimes
05:23 AM XXCoder: it happened to mess up and stopped tool change after it put toool changer in, released tool and spindle is rised, ready for tool changer to rotate
05:23 AM XXCoder: so tool is in tool changer, and spindle dont have tool and are risen.
05:24 AM XXCoder: I had to reset it, then pressed recovery button
05:24 AM XXCoder: it asked if it had tool in spindle. (n)
05:24 AM XXCoder: it asked if there was tool in toolchanger. (y)
05:25 AM XXCoder: it reversed the tool changer, it seemed ok, so I tested it by changing tool
05:25 AM XXCoder: boom it didn't rise the spindle to correct spot, so tool in tool changer hit spindle
05:25 AM XXCoder: bah
05:25 AM XXCoder: so reset and recovery, this time I removed tool and pressed no
05:25 AM XXCoder: it was fine afterwards.
05:26 AM jthornton: what a mess
05:26 AM XXCoder: yah. it knows theres tool in tool changer and no tool in spindle. it should rise spindle.
05:29 AM XXCoder: oh yeah I finally got the mini crossbows
05:29 AM XXCoder: its pretty cool
05:29 AM XXCoder: one was super crappy and lost 3 screws in short time lol
05:29 AM XXCoder: other one is great :)
05:29 AM jthornton: mini crossbows?
05:30 AM XXCoder: yep lemme get link
05:31 AM XXCoder: https://www.wish.com/c/5916d780ab1d8d0946fe7e3d
05:32 AM jthornton: does it shoot toothpicks?
05:32 AM XXCoder: yeah
05:32 AM XXCoder: it comes with some
05:32 AM XXCoder: those has one end flat
05:32 AM XXCoder: works with regular just fine tho lol
05:36 AM IchGucksLive: hi
05:36 AM XXCoder: hey IchGucksLive is mini crossbow illegal where you live? heh
05:36 AM IchGucksLive: need to google
05:37 AM IchGucksLive: oh yeh it is for shure
05:38 AM XXCoder: see the wish link above lol
05:38 AM XXCoder: really the tiny ones illegal? weird.
05:39 AM IchGucksLive: all that shoots somthing is iligal even cherry pickers
05:39 AM XXCoder: jthornton: its pretty surpising strong lol if steel rods it could probably go much futher
05:39 AM XXCoder: dang
05:39 AM IchGucksLive: but there all over
05:40 AM IchGucksLive: chust a quick in as i needed to get negativ votings to my CN dealer
05:40 AM IchGucksLive: wrong ,Nothing,Bad it is a miss on that price eighter
05:41 AM IchGucksLive: 16hr local delivering but 4times the price
05:41 AM jthornton: make some osmium bolts for it
05:41 AM XXCoder: lol
05:41 AM XXCoder: thinly coated sodium metal bolts ;)
05:41 AM IchGucksLive: XXCoder: you can go to the local reddealer it will got them
05:42 AM IchGucksLive: may SM shops also have them
05:42 AM XXCoder: so far no such thing as mini crossbow in stores here
05:42 AM IchGucksLive: you goit the wrong stores
05:42 AM XXCoder: possibly heh
05:43 AM IchGucksLive: ok im off
05:44 AM IchGucksLive: till later
08:25 AM JT-Shop: lol Hello i saw your ad and i am satisfied with the condition and price. But the best way i can pay for this, is check only then after it clears at your Bank with no problem then i can arrange for pickup .if this is OK, please text me now your full name and mailing address where the check will be mailed to. Hope to read from you soon because i am getting it for my relative
08:25 AM JT-Shop: Thanks
08:25 AM archivist: phishing?
08:26 AM archivist: pressure washing a genset is wet!
08:26 AM JT-Shop: almost they didn't provide a number to text to lol
08:30 AM fraaank_: "sets the command pulse number for 1 revolution of the motor" (Servo tuning) means steps/rev??? then it says "units: after multiplied by 4"
08:34 AM JT-Shop: if the drive takes step and direction input then LinuxCNC thinks it's a stepper and any tuning is done in the drive AFAIK
08:34 AM archivist: I dont understand why step/dir servos exist
08:35 AM fraaank_: yes, im tuning the driver
08:35 AM fraaank_: pain in the ass
08:36 AM fraaank_: http://imgur.com/a/MDJ5j
08:36 AM sync: archivist: because people use them from dumb controls like PLCs
08:36 AM JT-Shop: archivist: I've used step/direction servos in many automation applications driven by a PLC output
08:37 AM fraaank_: this drive takes phase pulse and positive+negative, i dont really know what they mean but anyway.. lol
08:47 AM JesusAlos1 is now known as JesusAlos
08:59 AM JT-Shop: it should have auto tune
09:08 AM frank__lol: sry, couldnt get to read what you've told me heh
09:08 AM frank__lol: i was going to move the tower pc to update servos parameters
09:09 AM frank__lol: wait i have it on my cellphone nevermid :D
09:10 AM Frank_10: yep; i will try that auto tune; however im afraid my load inertia is to big for the auto tune
11:02 AM codepython777: Anyone has any recommendation for a drill bit that can make holes in carbon fiber? (Preferably something I can buy in Florida locally)
11:02 AM codepython777: I was trying -craftsman - wood/metal/plastic drill bits - they like to walk
11:04 AM archivist: try a slot drill
11:04 AM archivist: its short and stubby wont bend
11:07 AM codepython777: archivist: For cf holes, don't you need something pointed?
11:07 AM archivist: I dont play with cf
11:08 AM archivist: see what your cause of wander is, drill bending, machine slop/flex or work clamping
11:08 AM jdh: I think there is a carbon fiber drill bit shop in key west
11:29 AM Vitran: Question. Would a bradpoint drill work on carbon fiber?
11:29 AM ChanServ changed topic of #linuxcnc to: LinuxCNC is a linux-based open-source CNC control. | Latest releases: 2.7.11 | http://www.linuxcnc.org
11:29 AM SpeedEvil: depends what you mean by work
11:29 AM SpeedEvil: it will make a hole, probably
11:29 AM Vitran: Cut a hole without fraying everyhting around it
11:30 AM Timbo_ is now known as Timbo
11:35 AM Loetmichel: codepython777: Tungsten carbide.
11:36 AM Loetmichel: any HSS will likely be dull after 2 holes. IF the last even one.
11:37 AM Loetmichel: what size drill do you want?
11:37 AM Loetmichel: if small: try drill bits made for PCB
11:37 AM codepython777: 1/8
11:37 AM Loetmichel: they are full tungsten carbide, inexpensive and last a while in CF
11:38 AM Loetmichel: https://www.sorotec.de/shop/Cutting-Tools/sorotec-tools/1-8-tools/Drills/Drills-023175/
11:38 AM Loetmichel: https://www.sorotec.de/shop/Cutting-Tools/sorotec-tools/1-8-tools/Drills/Drills-317565/
11:38 AM Loetmichel: something like these
11:39 AM Loetmichel: sould be aviable in the us also
11:42 AM codepython777: Loetmichel: http://www.homedepot.com/p/DEWALT-1-8-in-x-3-in-Carbide-Tipped-Percussion-Drill-Bit-DW5221-T/202519052 ?
11:43 AM archivist: absolutely not that one
11:43 AM Loetmichel: codepython777: perkussion drill bits are not sharpened. they are for concrete
11:43 AM codepython777: OH - ok
11:43 AM Loetmichel: doesent work for carbon
11:43 AM codepython777: Thanks
11:44 AM Loetmichel: they are like a rotating chisel
11:44 AM codepython777: Titanium 1/8" (no carbide?)?
11:44 AM codepython777: they have cobalt - for hardened steel
11:44 AM Loetmichel: anything not carbide(or diamond) will be dull in seconds in carbon fibre
11:44 AM archivist: those wont last long
11:45 AM codepython777: so carbide or diamond are my only choices.
11:45 AM Loetmichel: when i worked for the model company we even had diamond dust coated tungsten carbide mill bits for carbon.
11:46 AM Loetmichel: makes the difference between 10m milling path in carbon (uncoated carbide) or 100m (coated)... the drills last a while though
11:46 AM Loetmichel: even uncoated
11:46 AM codepython777: http://www.homedepot.com/p/Dremel-1-8-in-Spear-Shaped-Tungsten-Carbide-Cutter-for-Steel-Stainless-Steel-Iron-Ceramics-Plastics-and-Hard-Wood-9903/202263217 ?
11:46 AM miss0r2: I just had a good laugh. I'm the 'bestman' at a wedding tomorrow. and I have to write a speech. I just looked up some guidelines for what this particular speech should be about. Guideline number one: "Prepare the speech in good time, so you do sweat about being completely idealess the evening before the wedding".... hehe check
11:47 AM codepython777: Loetmichel: I'm just drilling holes in CF
11:47 AM Loetmichel: i made this: with a single 3mm TC drill: https://www.youtube.com/watch?v=mj8sGEf8Wf8
11:48 AM Loetmichel: result: http://www.cyrom.org/palbum/main.php?g2_itemId=5251&g2_imageViewsIndex=1
11:49 AM Loetmichel: codepython777: that "spear head" mill bit will not drill well
11:50 AM codepython777: I dont think I'll find anything locally for this
11:50 AM pink_vampire: how did you paint it?
11:50 AM archivist: I bet you have a local trade tooling supplier
11:51 AM Loetmichel: codepython777: ordering from the internet is no option?
11:51 AM pink_vampire: i see now it is CF
11:51 AM Loetmichel: pink_vampire: me?
11:51 AM Loetmichel: its 1,6mm thick CF
11:51 AM codepython777: Loetmichel: I was hoping to do this today
11:51 AM pink_vampire: i thought it was aluminum
11:52 AM Loetmichel: no
11:52 AM Loetmichel: that would be a BIT more heavy...
11:52 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=5254&g2_imageViewsIndex=1
11:52 AM pink_vampire: look nice
11:53 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=5245&g2_imageViewsIndex=1 <- pretty sturdy, too... (those milk tetra packs are 1kg each ;)
11:54 AM pink_vampire: look nice
11:57 AM Loetmichel: only problem: quite expensive if you do a "short touchdown" ;)
11:58 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=4088&g2_imageViewsIndex=1 <- ready for takeoff
11:59 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=4091&g2_imageViewsIndex=1 <- five minutes later ;)
12:01 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=4097&g2_imageViewsIndex=1 <- was a quick fix though ;)
12:02 PM pink_vampire: look very nice!
12:04 PM JT-Shopp: Loetmichel: looking good, interesting way you made the landing skids
12:04 PM codepython777: Loetmichel: https://www.mcmaster.com/#standard-drill-bits/=18p20lt - $18 range
12:05 PM codepython777: Loetmichel: Short-Length Drill Bits for Carbon Fiber, Fiberglass, and Graphite Diamond-Coated Carbide - $35 - is that worth the price?
12:06 PM JT-Shopp: do you have a million holes to drill?
12:07 PM JT-Shopp: http://gnipsel.com/images/weyland-s500/Weyland-S500-03.jpg
12:08 PM Loetmichel: PCB drill bits in carbide and 1/8" are about $5
12:08 PM codepython777: I've to drill at least 200 holes
12:09 PM Loetmichel: JT-Shop: that was my first copter back then.. the landing skids were simple 2.5mm thick glass fibre rods with black gelcoat... worked well, only problem was that they were a bit "springy" ;)
12:09 PM codepython777: Loetmichel: which autopilot are you using?
12:10 PM Loetmichel: mikrokopter.de
12:10 PM Loetmichel: old FC 1.3
12:10 PM Loetmichel: not the newfangled 2.x stuff ;)
12:11 PM JT-Shop: I just need to figure out where to put the receiver antennas
12:13 PM Loetmichel: JT-Shop: http://www.cyrom.org/MC/quadcopterhops2.avi <- sorry for the potato cam. it was a LONG time ago
12:14 PM JT-Shop: even though it bounced it didn't flip over :)
12:15 PM Loetmichel: nowadays my frames are made from aluminium... WAY cheaper to repair.
12:15 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=12997&g2_imageViewsIndex=1
12:16 PM Loetmichel: and 1225gr for a hexacopter THIS size isnt bad, either ;)
12:22 PM IchGucksLive: hi
12:26 PM JT-Shop: Loetmichel: did you machine the arms and legs?
12:26 PM Loetmichel: yes
12:26 PM Loetmichel: from 15mm square aluminium tube
12:27 PM JT-Shop: nice!
12:27 PM roycroft: did the tubing cost you an arm and a leg?
12:27 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=12982&g2_imageViewsIndex=1 <- and the legs only have a single screw to hold in the "bent" shape
12:28 PM Loetmichel: roycroft: on the contrary: a meter of this tube is less than 10 eur at the local hardware store
12:28 PM pink_vampire: very nice
12:28 PM JT-Shop: is it soft aluminum like gummy to machine?
12:28 PM Loetmichel: its pretty soft
12:29 PM Loetmichel: but machineable if you dont overdo it with the feed and rpm
12:29 PM Loetmichel: a spray can with wd40 helps a lot, too ;)
12:29 PM JT-Shop: I'll have to remember that trick for soft aluminum
12:30 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=12973&g2_imageViewsIndex=1 <- i am still pretty proud about that idea with the single screw bend.
12:30 PM Loetmichel: every steel screw is dead weight
12:32 PM roycroft: wd40 is my go-to lubricant for machining aluminium
12:32 PM JT-Shop: I think the whole design is genius!
12:33 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=13006&g2_imageViewsIndex=1 <- inside the center plate sandwich... power distribution to the six ESCs ;)
12:34 PM IchGucksLive: Loetmichel: are you nor going airborn
12:34 PM Loetmichel: ?
12:35 PM IchGucksLive: copter builder
12:35 PM Loetmichel: i havent flown them in a few years now... other hobbys took precedence
12:36 PM Loetmichel: but they are still operational, bar charging the transmitter and some Lifepo4 packs for the copters
01:52 PM phipli: wibble
01:55 PM Tom_L: wabble
01:55 PM IchGucksLive: wobble Gn8
03:03 PM pink_vampire: hi
03:04 PM pink_vampire: i need some advice about handling small pieces of stock materials.
03:06 PM BeachBumPete: pink_vampire handling them how?
03:07 PM pink_vampire: how to keep them and also get easy access to each piece
03:08 PM BeachBumPete: you are talking about storage or machining them?
03:08 PM pink_vampire: storage
03:08 PM BeachBumPete: oh
03:09 PM BeachBumPete: I have a couple large plastic heavy duty rubber maid bins I keep under the lathe where I stuff smaller pieces of stock until I need to scrounge for one LOL
03:09 PM BeachBumPete: one for steel bits and one for ally
03:10 PM pink_vampire: but you never ever going to dig in to that bin
03:10 PM BeachBumPete: actually I do all the time
03:11 PM BeachBumPete: whenever I need a small piece or want something to practice tig welding on or whatever
03:11 PM BeachBumPete: I guess it depends on what your definitions of small pieces are too
03:12 PM pink_vampire: 2x2 to 10x10
03:12 PM pink_vampire: inch
03:12 PM pink_vampire: 1/2" to 3/4" thick
03:12 PM BeachBumPete: yeah that is about what I stuff in the bins... lots of pieces that were mistakes or just drop pieces
03:13 PM BeachBumPete: often times they are good for something else and are too decent to just toss in the trash
03:13 PM BeachBumPete: the steel bin gets kinda heavy sometimes tho and I gotta get in there and purge it of the more useless pieces
03:13 PM pink_vampire: so now i have a bin.. but i'm looking for something better
03:14 PM BeachBumPete: I have seen some nice rack designs for under the lathe bed that are on wheels that you can move around easier
03:14 PM BeachBumPete: my bins are pretty big LOL
03:15 PM pink_vampire: i have something about the size of a lowes bin
03:16 PM pink_vampire: i just want better access to each individual piece
03:17 PM BeachBumPete: I can see that I would like it as well but there is just so many smaller pieces that I just deal with rummaging thru the bins LOL I have a bunch of nice heavy shelving units out there but I got other stuff on them. I suppose you could make or buy some good shelves and use them...
03:18 PM pink_vampire: i'm tring to google some stuff..
03:19 PM BeachBumPete: two of the shops I worked in had large double sided carts with heavy castors that had multiple cantilevered shelves on the sides for drop/scrap materials. They were labeled for the particular type of material and people got pissed off if you did not only put it in the right place but also labeled it before you did as to what type of alloy it was.
03:20 PM pink_vampire: i don't have much of that issues here..
03:20 PM pink_vampire: it's a home shope.
03:22 PM BeachBumPete: sure
03:23 PM miss0r2: Theres an easy fix for that, which I use all the time: I make most of my work out of mystery metal
03:24 PM BeachBumPete: mystery metal works great as long as the end use is just non essential or critical ;)
03:24 PM miss0r2: yeah :]
03:24 PM miss0r2: Most of my shop tools are
03:24 PM pink_vampire: miss0r2: what do you mean?
03:25 PM miss0r2: pink_vampire: mystery metal is just a common name for metals you don't know exactly what is
03:25 PM pink_vampire: I have some
03:25 PM pink_vampire: even even some i gut like that
03:26 PM pink_vampire: i have large bar of cold rolled steen (i hope) that is mystery metal
03:27 PM pink_vampire: and also large chunk of aluminum, about 6
03:27 PM pink_vampire: and also large chunk of aluminum, about 6X8X1 inch
03:28 PM pink_vampire: it has a punch mark on it 703A
03:28 PM miss0r2: I have around 500kg of mystery metals; steel, cast iron, bronce, brass, aluminium, stainless.. I like to go to the scrapyard and pick up stuff cheap
03:29 PM pink_vampire: miss0r2: same here :-)
03:29 PM pink_vampire: I live the 2024-T3 sheets.
03:29 PM pink_vampire: love*
03:31 PM miss0r2: I love milling in steel. any steel :]
03:32 PM miss0r2: even stainless people seem to be so afraid of
03:33 PM pink_vampire: i have a bench top mill.... so..
03:34 PM miss0r2: yeah... I understand why you love aluminium
03:34 PM BeachBumPete: I machine whatever but I really dislike tapping stainless... other than that I cut whatever LOL
03:34 PM miss0r2: i realy hate tapping aluminium
03:35 PM BeachBumPete: really? its so soft LOL
03:35 PM miss0r2: thats my issue with it. Packs up everything
03:35 PM BeachBumPete: I love Morse spiral flute taps
03:35 PM pink_vampire: i did some projects in steel but, 2024-t3 vs 6061, .. the 2024 is just sooo easy to cut, and never pack the end mill.
03:37 PM miss0r2: I think I need a mister, if i'm realy going to enjoy aluminium
03:37 PM miss0r2: The flood coolant I run does not have enough pressure to realy clear out properly for aluminium
03:38 PM BeachBumPete: mine does but I gotta make sure it is directed properly before I really dig deep
03:38 PM pink_vampire: try smaller nozzle
03:39 PM BeachBumPete: I actually have two nozzles
03:39 PM miss0r2: pink_vampire: I've already reduced it alot. all four of them.
03:39 PM BeachBumPete: one is a bit larger than the other
03:40 PM miss0r2: What I realy need is a more powerfull coolant pump I think
03:40 PM pink_vampire: how much flow you have?
03:40 PM miss0r2: I have no idea :)
03:40 PM pink_vampire: what pump you have?
03:40 PM CaptHindsight: clogged plumbing?
03:41 PM BeachBumPete: mine is pretty heavy duty 3 phase pump and I run it off a VFD
03:41 PM miss0r2: pink_vampire: I don't know. I've never written it down. Its a three fase something. I can't remember. The mill is bourn with it, and it is tugged away pretty good.
03:41 PM BeachBumPete: I can probably dial up the freq on it for more speed but there is a point of diminishing returns when it comes to volume
03:42 PM miss0r2: CaptHindsight: I don't think it is. the flow is 'ok', but not to be considered high pressure
03:42 PM pink_vampire: I cut dry, and it work ok,
03:42 PM miss0r2: in aluminium ? :o
03:42 PM pink_vampire: yes
03:43 PM miss0r2: very light cuts? only 1 or two flutes then?
03:43 PM pink_vampire: never!!
03:43 PM pink_vampire: you must go full depth of cut.
03:43 PM miss0r2: I have a very serious fear of packing my tools in aluminium :]
03:43 PM pink_vampire: http://i.imgur.com/tJb46SW.png
03:44 PM pink_vampire: http://i.imgur.com/94rzIqT.png?1
03:44 PM miss0r2: Looks nice
03:44 PM pink_vampire: http://i.imgur.com/nhoAbXq.png
03:45 PM pink_vampire: for a bench top with 1000 rpm you can't ask for more
03:45 PM BeachBumPete: 1000RPM??
03:45 PM pink_vampire: yes 1,000
03:45 PM BeachBumPete: jeez that is really slow
03:46 PM BeachBumPete: hell I spin my edge finder at that RPM
03:47 PM pink_vampire: you can go up to 2000 but then your motor will die. so i keep it one thousand (1000) and it is slow, and cut very nice)
03:47 PM BeachBumPete: what kind of machine is it?
03:48 PM pink_vampire: g0704
03:49 PM JT-Shop: hey Pete http://gnipsel.com/images/weyland-s500/
03:50 PM BeachBumPete: JT-Shop looks nice man
03:50 PM pink_vampire: JT-Shop: those beams are 3d machined?
03:50 PM BeachBumPete: pink_vampire isnt there a belt drive setup for those?
03:51 PM JT-Shop: no they are injection molded
03:51 PM pink_vampire: BeachBumPete: there it,, but it will take it to 2k to 4k..
03:51 PM XXCoder: hey all
03:51 PM BeachBumPete: thats a helluva lot better than 1k
03:52 PM pink_vampire: hi XXCoder
03:52 PM JT-Shop: I got the ESC's lined out today just need my FPV camera so I can watch it on the ground station
03:52 PM BeachBumPete: JT-Shop how much do you have tied up in that monster?
03:53 PM pink_vampire: BeachBumPete: but the torque go down, so you need bigger motor.. and so on.. so i stick to the 1000, and happy.
03:53 PM BeachBumPete: pink_vampire whatever works I guess. I can't imagine cutting aluminum at 1k tho. I hate that my mill only goes to 6kLOL
03:54 PM pink_vampire: maybe one day i will upgrade the spindle to high speed spindle.
03:54 PM pink_vampire: but for now, I want a laser cutter
03:54 PM BeachBumPete: you could probably adapt a router to the thing like I did to the VMC
03:55 PM BeachBumPete: then at least for softer stuff you can kickass
03:55 PM roycroft: you can get a "laser" cutter, but it will cost you ONE MILLION DOLLARS!
03:55 PM JT-Shop: BeachBumPete: $159 in the air frame, motors and esc's
03:55 PM XXCoder: heh robodrills at work have mist collector because spindle spins so fast it vaporizes coolant. side effect is that it also cools down interior LOL
03:56 PM BeachBumPete: JT-Shop damn thats cheap can you send me some links for what you bought. I would not mind building one like that
03:56 PM pink_vampire: how much a robodrill cost?
03:56 PM JT-Shop: $228 for the Eagle Tree Vector FC with V2 GPS and compass and power thingy
03:57 PM XXCoder: pink_vampire: hundred thousand range, not too sure exact
03:57 PM JT-Shop: https://www.amazon.com/gp/product/B01MZ6BV61
03:57 PM XXCoder: lemme look
03:57 PM JT-Shop: https://www.amazon.com/gp/product/B06XRJMVCC
03:57 PM pink_vampire: it is so funny to call to a such a crazy VMC a robo drill..

03:58 PM BeachBumPete: only 20A?
03:58 PM JT-Shop: https://www.banggood.com/RunCam-Eagle-2-800TVL-CMOS-2_1mm2_5mm-43169-NTSCPAL-Switchable-Super-WDR-FPV-Camera-Low-Latency-p-1163434.html
03:58 PM JT-Shop: yea the motors only draw 15A max
03:59 PM BeachBumPete: is that enough thrust?
03:59 PM JT-Shop: check out the amp thrust chart on the motor page
03:59 PM BeachBumPete: I hear good things about that runcam stuff
03:59 PM XXCoder: pink_vampire: https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2047675.m570.l1313.TR4.TRC2.A0.H0.Xrobodrill.TRS0&_nkw=robodrill&_sacat=0
03:59 PM JT-Shop: https://fpvheadquarters.com/collections/fpv-5-8-ghz-video-receivers/products/tbs-unify-pro-5-8-ghz-video-transmitter
04:00 PM XXCoder: compare prices, thats for used and rather old so yeah
04:00 PM JT-Shop: I think that is the whole build
04:00 PM JT-Shop: I should have gotten the TBS Unify Pro HV VTX though
04:00 PM BeachBumPete: I can't believe someone can sell that airframe for $40
04:02 PM JT-Shop: got nice stiff arms unlike the 330 one I got
04:02 PM BeachBumPete: I was gonna cut my own frames on the VMC in Carbon plate but after looking at the prices for ready to go frames I was like why the hell bother LOL
04:03 PM JT-Shop: right now I'm at 850 grams of the predicted weight of 1130 grams
04:04 PM JT-Shop: 1/2 throttle thrust with CF props is 1420 grams
04:04 PM BeachBumPete: its not like you are gonna be doing acrobatics with it right ;)
04:04 PM JT-Shop: I'm the same way for $40 and 15 minutes of time I have a 500mm quad
04:05 PM BeachBumPete: that is what I wanted to build actually
04:05 PM JT-Shop: no, but you can if you want to
04:05 PM BeachBumPete: so its nice that you are already there
04:05 PM JT-Shop: I want to fly waypoints with the gps
04:05 PM BeachBumPete: keep us informed about it and I might just build the same thing
04:05 PM JT-Shop: eagle tree vector will fly way points and auto land if you want
04:06 PM BeachBumPete: sweet
04:07 PM JT-Shop: looks like I'll end up at 1200 grams with the battery so still under 1/2 throttle thrust :)
04:08 PM XXCoder: LOL https://www.youtube.com/watch?v=uj-jssZfcTk wait and see what they use for pedals. lol
04:08 PM XXCoder: no way is THAT safe for real cars :P
04:11 PM JT-Shop: I like the Return To Home feature that's great to have if you have radio problems
04:13 PM BeachBumPete: sure is man great build
04:13 PM XXCoder: JT-Shop: saw the video? lol
04:16 PM Deejay: gn8
04:16 PM JT-Shop: lol
04:17 PM JT-Shop: looks like even with the included Emax 1045 props I'll be able to hover at a tad under 1/2 throttle so weight to thrust is good
04:51 PM CaptHindsight: JT-Shop: order arrived much thanks
04:58 PM CaptHindsight: I ordered cables with female connectors on one end and males on the other
04:59 PM CaptHindsight: the ones i got have males on one end and female on the other
04:59 PM CaptHindsight: so i should be able to make them work
05:00 PM JT-Shop: turn them around
05:01 PM CaptHindsight: sorry I got some email questions from some real winners today
05:01 PM JT-Shop: I hear ya
05:02 PM roycroft: do any folks here have laser cutters, or are familiar with them?
05:02 PM roycroft: i'm wondering how powerful a laser is needed to cut leather
05:03 PM roycroft: up to, say, 8mm thick
05:04 PM CaptHindsight: maybe a real 30W
05:04 PM CaptHindsight: or 50-100W ChinaCo CO2 tube
05:05 PM roycroft: thanks
05:05 PM roycroft: i was thinking 40w or so would do it
05:05 PM roycroft: sounds like i'm in the ballpark
05:05 PM roycroft: a 40w laser would cost a few pennies
05:06 PM roycroft: but i kind of figured it would require a decent power laser
05:06 PM roycroft: those 2w ones are basically toys
05:06 PM CaptHindsight: there's a 100W CO2 RF laser for ~$2500 on ebay
05:07 PM CaptHindsight: you can PWM them to adjust power output
05:09 PM XXCoder: theres apparently 100w diode laser but good luck affording one
05:09 PM XXCoder: ah missed that
05:13 PM roycroft: i can get a 40w co2 laser tube for about $100
05:16 PM XXCoder: yeah co2 tubes cheapest way to get good laser
05:21 PM JT-Shop: BeachBumPete: it flys!
05:24 PM BeachBumPete: JT-Shop awesome man but its all BS unless there's video ;)
05:26 PM JT-Shop: need to balance the crappy props lol, waiting for a battery to charge, I just lifted off for a few seconds into a hover with a storage charge on a battery
05:26 PM * JT-Shop wonders where his prop balancer is...
05:26 PM BeachBumPete: Stick it in your VMC LOL
05:33 PM JT-Shop: need some lead based paint to balance them lol
05:48 PM Loetmichel: JT-Shop: its easier to carve a bit off of the outer edge of the prop
05:48 PM Loetmichel: or place some scotch tape on the underside of one blade
05:48 PM Loetmichel: (the lighter of course
05:48 PM Loetmichel: )
05:48 PM * Tom_L used to have a good prop balancer
05:49 PM Tom_L: back in the boat racing days
06:05 PM JT-Shop: yea I just wrapped some scotch tape around from trailing edge to trailing edge for now
06:06 PM Redbull: I'm having a hell of a time getting the thcud module by jthornton to work. I've read through the man page on it so many times i'm going cross eyed
06:06 PM JT-Shop: sorry about that
06:08 PM Redbull: No worries, I think i'm missing something to do with hijacking the Z axis commanded position. But its not mentioned in the man page
06:09 PM JT-Shop: basically you have to trick LinuxCNC by lying about the actual position because the comp moved the axis from the commanded position
06:09 PM JT-Shop: should be the same description in the thc component but maybe I left something out of the thcud component
06:11 PM Redbull: yeah, i'm struggling with the hal configuration. I've looked closely at the thc man page also and didn't notice anything that i'm missing. I've used the sample/plasma-i something or other config as a reference to the z hijack deal with conecting stepconf to the right nets
06:11 PM Redbull: But after I get that, i'm getting following error when Z tried to move
06:12 PM Redbull: Anyway I could see a hal snippet of the relative Z axis code in the hal file?
06:13 PM JT-Shop: have you seen my plasma configuration files?
06:14 PM JT-Shop: http://gnipsel.com/shop/machine-shop.xhtml
06:16 PM JT-Shop: BeachBumPete: https://www.youtube.com/watch?v=hnMcWxh-ufE
06:16 PM Redbull: Thanks for the link! That's the first i've come across your page. Ill examine plasma.hal closely. Will you be around for a while on here?
06:16 PM JT-Shop: not much longer
06:17 PM Tom_L: mmm, boys n their toys
06:18 PM Redbull: JT-Shop: no worries, thanks for your help!
06:19 PM Tom_L: JT-Shop, how much air time do you get from a charge?
06:19 PM JT-Shop: I'm on early in the morning as jthornton from 5 to about 7am then of and on here in the shop till about 6pm or so
06:19 PM JT-Shop: depends on the battery Tom
06:20 PM JT-Shop: that battery is for my 220mm Tweaker 5" so not long as it is only 1300 mAh, the ones I'm getting are 4100 mAh for real flying
06:25 PM JT-Shop: can't do a whole lot till I have the FPV camera so I can see on the screen how many sat's I have for GPS etc
06:25 PM JT-Shop: I'll try some loiter mode tomorrow just assuming I have enough gps sats
06:28 PM JT-Shop: I should get ~30 minutes flying time at 1/2 throttle with 4100 mAh battery
06:33 PM JT-Shop: Tom_L: did you have a top flight magnetic balancer?
06:33 PM Redbull: JT-Shop: I've got the Z Hijack code setup the same as in your plasma.hal file but I just get a following error as soon as I try to jog, or any move. I should mention that i'm using steppers and I believe your setup is servo. I think the same method applies though
06:33 PM Redbull: **Any Z move, other X and Y are fine
06:34 PM JT-Shop: no, the thc is stepper only
06:34 PM JT-Shop: when the thc is no enabled the steps should just pass through
06:35 PM JT-Shop: open the show hal configuration and put the pins in the watch window
06:35 PM JT-Shop: and does Z move at all during a jog?
06:36 PM Redbull: Okay, Z does not move at all. I'm running a parport setup so I don't have "hm2_[HOSTMOT2](BOARD).0." its just stepgen.2.
06:37 PM Redbull: Will the module throw a following error if a jog is done while thc-enable = true?
06:38 PM JT-Shop: no, I have mine enabled all the time by default and I can jog... I'd bet your missing some tiny ting
06:38 PM JT-Shop: thing even
06:40 PM Redbull: okay, yea i just prefer to leave it enabled also. I'm defininantly missing something
06:40 PM Redbull: Here's my hal file if you have a minute to take a look - https://pastebin.com/Rx0qKdtJ
06:41 PM Redbull: I'll throw you some beer money if we can get this thing working. I've got a some big aluminum sheets i gotta get out
06:50 PM JT-Shop: line 88
06:50 PM JT-Shop: axis.2.motor-pos-cm must go to zpos-cmd
06:50 PM JT-Shop: or it won't jog
06:51 PM JT-Shop: nm
06:52 PM Redbull: Yeah, the two line that are commented out are how i've been running this machine for the last 4 months. Just running small parts with a z touchoff routine. ATHC wan't a large priority until recently
06:53 PM JT-Shop: ah I see it thcud is not running in a thread... you forgot to addf it
06:57 PM Redbull: Your right, I did miss that. I've just added it, but i'm still getting the following error
06:58 PM JT-Shop: did you restart LinuxCNC
06:59 PM Redbull: I did, I restarted it twice hoping. That should have been the big fix lol. I must have another problem...
07:05 PM Redbull: I set thc-enable to false, left just the Z hijack commands intact along with the loadrt and addf to servo-thread. I still get the following error. Seems like it has something to do with the Z code...
07:06 PM JT-Shop: open a show hal config and put the pins in the watch window and see what is not moving when you jog
07:06 PM * JT-Shop wanders inside for the night
07:10 PM Redbull: JT-Shop: I'll do that! Thank's for your help!!
07:24 PM necronian: I just started setting up my 6040. It came with limit switches installed, is there an easy way for me to figure out which pins they are on without having to break everything back down to trace the wires?
07:26 PM Loetmichel: necronian: LPT-port?
07:27 PM necronian: Loetmichel: Yes, I already have the x,y and z axis moving actually
07:27 PM Loetmichel: there is a debug component in linuxCNC
07:27 PM Loetmichel: Halview IIRC
07:28 PM Loetmichel: somewhere in the menues under machine i belive. (just have no linuxCNC running right now and its a looong time since i needed that)
07:28 PM Loetmichel: there you can View all lpt port pins
07:29 PM Loetmichel: simply view them and press the limit switches one by one
07:29 PM necronian: Loetmichel: ah okay thanks, I found Hal meter and hal scope so it must be one of those
07:30 PM Loetmichel: hal scope
07:30 PM Loetmichel: you have to switch on the pins you want to see though
07:38 PM necronian: Loetmichel: Thank you, took a minute for me to figure it out but I have it now
07:39 PM Loetmichel: de nada
09:58 PM LeelooMinai: The White House show is on the Gladiator level now - lol @ McCain doing the Roman arena thumb down thing.
10:13 PM pcw_home: Hmm, leftover asparagus with blackbean and tofu was a bit hit with the sheep
10:13 PM jdh: heh, sounded kinda weird until you got to 'with the sheep'
10:19 PM Tom_shop is now known as Tom_shop3
10:21 PM Tom_shop3 is now known as Tom_shop
10:22 PM CaptHindsight: with the sheep vs with sheep
10:42 PM LeelooMinai: Anyone has laser distance measure? I have some doubts if I can replace a tape measure with it - seems accurate to 2mm or so, which is kind of lame.
10:44 PM LeelooMinai: On the other hand when I had to measure distance betwwen the bottom and the top of the door opening with a tape, for example, it was a bit frustrating.
10:48 PM Tom_L: 82"
10:49 PM LeelooMinai: No, I mean real measure, not theoretical.
10:49 PM Tom_L: that's the standard rough opening for a prehung door
10:50 PM Tom_L: 82.5 excuse me
10:50 PM LeelooMinai: Right, well, I already kind of trolled myself, so next time I will try not too... I nicely renovated the door opening with vinyl cladding, etc., but then found that the opening for the screen door has a barell shape...
10:51 PM LeelooMinai: So, now I have a bit of a problem:)
10:52 PM Tom_L: those are cut to fit inside a standard door moulding too
10:52 PM LeelooMinai: It's wider in the middle and narrower at top and bottom.
10:52 PM Tom_L: it's not plum
10:52 PM LeelooMinai: It's not anything - it has a barell shape.
10:52 PM Tom_L: shim it
10:53 PM LeelooMinai: Not really possible now I think, well, unless I can do it from inside somehow.
10:53 PM Tom_L: you can drive the shims from either side
10:53 PM Tom_L: i generally use 2 opposing shims so it's somewhat flat
10:54 PM LeelooMinai: Hmm, I guess if I took off the frame/moulding/whatever it is called from inside, maybe I could have access. But not 100% sure - I could just see drywall and then what.
10:54 PM Tom_L: trim the drywall back like it's supposed to be then you can see the frame gap
10:55 PM LeelooMinai: I looked at some pics and seems there will be king stud and shorter stud by it.
10:55 PM Tom_L: the shorter ones support the header plate
10:55 PM Tom_L: a requirement on any window or door opening
10:56 PM LeelooMinai: Seems it's called "jack stud".
10:56 PM LeelooMinai: Right, ok, so I guess I need access to the space between those two studs for the shim.
10:56 PM Tom_L: it will make things easier in the end
10:57 PM LeelooMinai: And then if I drive it in the middle, maybe I can take the bow off. Unless it will instead move the king stud or something...
10:57 PM Tom_L: it shouldn't
10:57 PM LeelooMinai: I mean drive the shim.
10:57 PM Tom_L: it may a tiny bit
10:57 PM Tom_L: that's how it's done
10:57 PM LeelooMinai: Right, I guess it's worth trying.
10:58 PM Tom_L: i shim top middle and bottom
10:58 PM Tom_L: both sides
10:58 PM Tom_L: so it's plum and square
10:58 PM LeelooMinai: Yes, well, I mean I am not making new house, it's already shimmed I assume.
10:58 PM Tom_L: maybe it shifted
10:59 PM LeelooMinai: Well, something is wrong for sure - the bow is 1/4 inch on each side in the middle.
11:00 PM Tom_L: you may also want to shim with thin plywood along with the shims if needed
11:01 PM Tom_L: then run a nail or screw thru the shim
11:01 PM Tom_L: finish nail
11:01 PM LeelooMinai: Right, I only wonder about the drywall - do they usuall cover the jack stud with it or it ends earlier?
11:01 PM Tom_L: both
11:02 PM Tom_L: the door trim hides the gap
11:02 PM Tom_L: and is nailed to the door frame and the jack stud
11:02 PM LeelooMinai: Er, so how I am supposed to access the space between those jacks with drywall on top of them?
11:02 PM LeelooMinai: I mean those studs
11:02 PM Tom_L: box knife the edge off it
11:02 PM Tom_L: or whatever
11:03 PM LeelooMinai: I mean I know how to take off drywall, but then I have to replace it...
11:03 PM Tom_L: you just need enough access to add the shim
11:03 PM Tom_L: no you don't
11:03 PM LeelooMinai: A, so just one small piece under the trim?
11:03 PM Tom_L: just carve the edge away enough to see the gap between the door frame and the jack stud
11:04 PM LeelooMinai: A, ok, I guess that's not too much work.
11:04 PM Tom_L: remove the trim on one side to get access
11:04 PM LeelooMinai: Right, ok
11:05 PM LeelooMinai: I wish I had a plan of my house - like one they should give the owners when its built:/
11:05 PM Tom_L: one summer (a long time ago) i helped a friend frame a whole apartment complex
11:07 PM Tom_L: one crew did the walls, the other did the floor trusses and floor underlayment
11:07 PM Tom_L: fun walking on a 6" wall 2 storries up carrying a truss in each hand
11:08 PM LeelooMinai: They should teach how houses are built in elementary school or something...
11:08 PM LeelooMinai: It's very useful later when one actually needs to take care of a house.
11:09 PM LeelooMinai: Initially I had zero knowledge of how houses are built here - did not even know what a stud is:)
11:10 PM Tom_L: mine was initially lath and plaster walls and no basement
11:10 PM Tom_L: now it's sheetrocked with a basement
11:10 PM LeelooMinai: Because in Europe I was living in a multi-store concrete contraption.
11:10 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/temp/house/1.jpg
11:11 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/temp/house/2.jpg
11:11 PM LeelooMinai: Ok, that's not something I would like to do...
11:11 PM Tom_L: i hired the concrete work done but did ALL the rest
11:11 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/temp/house/4.jpg
11:12 PM Tom_L: a view from inside looking out
11:12 PM LeelooMinai: lol, I wonder if one could modify a house to have multiple levels under ground..
11:13 PM Tom_L: until you reached the water table then you'd have to come up with a drainage plan
11:13 PM LeelooMinai: Could be problematic considering there is foundation there, probably.
11:13 PM LeelooMinai: Well, but imagine having a huge workshop level suddenly.
11:15 PM LeelooMinai: I am googling and seems that yes, you can. In Sims 3...
11:24 PM LeelooMinai: lol, in my city: "Do I need a permit to finish my basement?" "Yes. If you are finishing an unfinished area, a permit is required – especially if it contains a bedroom. Permits are also required if you’re adding a bedroom to a previously finished basement."
11:28 PM LeelooMinai: O, something related to this channel: "he city's bylaw governing the keeping of fowl in non-agricultural areas of the city was approved by council in November of 2016. Citizens in Kitchener are now able to keep up to four chickens in backyard coops."
11:28 PM LeelooMinai: Wee...?
11:29 PM LeelooMinai: Found it under "urban chickens"
11:30 PM SpeedEvil: Does it define chicken?
11:31 PM LeelooMinai: Like what... Chicken is a chicken - it's not like you can keep emus there:)
11:32 PM SpeedEvil: https://www.youtube.com/watch?v=vX4Jh-44-Nk - related
11:33 PM LeelooMinai: I almost thought it's someone wearing a costume...
11:34 PM LeelooMinai: ... and the first comment: "Wait a minute. This thing is effin HUGE. seriously thought it was a man stepping out in a chicken costume at first. smh."
11:41 PM LeelooMinai: Heh, I finding weird things about my city - they even have a special site for internet speed testing.
11:41 PM LeelooMinai: https://performance.cira.ca/kitchener
11:44 PM XXCoder: upload 2.8 mbps, download 6.8 mbps
11:44 PM LeelooMinai: In theory I have 65Mbps line
11:45 PM XXCoder: its supposed to be 11 mbps.
11:45 PM XXCoder: love internet access test sites that comcast dont know
11:45 PM XXCoder: because otherwise they cheat
11:46 PM LeelooMinai: Hmm, only gor 21Mbps download - fail
11:48 PM LeelooMinai: lol, and went to bell.ca test speed - somehow they think I have 99Mbps downlioad...
11:49 PM LeelooMinai: XXCoder: Can you test this place? http://support.bell.ca/Internet/Internet-Speed-Test
11:49 PM XXCoder: looking
11:49 PM LeelooMinai: I wonder if they have something broken or what...
11:50 PM LeelooMinai: Upload is ok though - 10Mbps for me.
11:50 PM XXCoder: it doesnt work for me
11:51 PM XXCoder: its in infinite loop of asking me where im at and what language
11:51 PM LeelooMinai: Err, just tried http://speedtest.att.com
11:51 PM LeelooMinai: And it shows 96Mbps... Maybe my modem is overclocked:)
11:52 PM XXCoder: heh gonna love "remove this object" plugin
11:52 PM XXCoder: im ignoring the setting window
11:53 PM XXCoder: 15 mbps down up 1.37 mbps
11:53 PM LeelooMinai: Ok, third place is showing 72Mbps - I guess I have more bandwidth than the plan is for.
11:54 PM LeelooMinai: XXCoder: Not very impressive:)
11:54 PM XXCoder: LeelooMinai: unless your isp knows that one, so they take off brakes for that test
11:54 PM LeelooMinai: XXCoder: I tried 4 sites now though.
11:54 PM XXCoder: comcast olviously knows the att test website, 18 mbps down, 11 mbps upload
