12:02 AM AchiestDragon: should be almost as stable as cast iron
12:12 AM rue_mohr: joinds between would be a problem
12:12 AM rue_mohr: THO
12:12 AM rue_mohr: I could make the bottom out of two C channels...
12:12 AM rue_mohr: arg, no
12:12 AM rue_mohr: 1/8" bit on aluminum
12:19 AM anonnumberanon: Your going for 4 axis machine ofc?
12:19 AM rue_mohr: ? no
12:20 AM anonnumberanon: Lol
12:20 AM anonnumberanon: Yolo...
12:20 AM AchiestDragon: https://drive.google.com/file/d/1lzw7Nb9Prtm5mFFJbuaH5hMnd6GOUSr0/view?usp=sharing
12:24 AM AchiestDragon: as you find its ok making the machine so you can cut alluminium , but its more usefull to on occasion be able to work on brass , copper and although only small cuts on mild steel also
12:31 AM AchiestDragon: although it would cost more , as welding it together tends to deform it you can get the surfaces that matter skimmed flat after welding assuming you used thick enough plate to make it worth wile
12:37 AM AchiestDragon: and only have a small amount of error on the z axis like less than a mm out at the ends
12:46 AM AchiestDragon: https://drive.google.com/file/d/1eprXGUu9NkvNgScBonM9xrDeOBS0mDcu/view?usp=sharing
12:57 AM rue_mohr: Tom_L, give up the things that nolonger serve you
12:58 AM rue_mohr: aka, empty the stuff in those drawrs and fill the kit witth things you do use
12:58 AM rue_mohr: from the dust, it looks like everything in that kit can go into a box in the corner
12:59 AM rue_mohr: I should take a pic of the goodies box for my next cnc
01:18 AM AchiestDragon: https://drive.google.com/file/d/1ikP79941RTADig2NutNEEfJZwPV8wRdM/view?usp=sharing
01:19 AM rue_mohr: not used a lot
01:19 AM rue_mohr: nice tho
01:19 AM rue_mohr: what brand it the millpress?
01:22 AM AchiestDragon: yea ,, actualy though that lathe is totaly unusable theres about 5mm of backlash in it and the spindle barings need replacing allong with the fact that someone had previosuly skimmed the bed with a 5mm cutter or something like that , the mill is a chinese one its ok but no way it will cnc convert without a lot of work , , and the dove tail locks need to be adjusted all the time to stop play in the axises
01:24 AM AchiestDragon: they cost arround £900 new , i got it cheap from someone who got it to cnc convert but gave up after seeing what needed to be done was a bargin at £200 and was never used
01:25 AM rue_mohr: AchiestDragon, the lathe is special equip, you need to know how to set it up right
01:26 AM AchiestDragon: but all that said i would not recomend it , if i got another i would prob go for a full size bridgeport , although that mill has a brigeport tooling compatable spindle
01:26 AM sydenkneee: hi
01:27 AM rue_mohr: I got an old busybee
01:28 AM AchiestDragon: that lathe is a german one they were pritty good but that perticular one is so warn in every aspect it is worth noting more than beeing an ornimental doorstop unfortunaly as its not posible to refurbish it any more
01:28 AM rue_mohr: https://i.ytimg.com/vi/mSJ7g91--Ak/hqdefault.jpg
01:28 AM rue_mohr: but mine isn't fuzzy
01:29 AM rue_mohr: http://www.hobby-machinist.com/data/attachments/25/25841-d84a2f56358a38eb0d6338153f71b625.jpg
01:30 AM sydenkneee: do you guys build robotic stuff?
01:30 AM rue_mohr: yup
01:30 AM AchiestDragon: the spindle moves but the pully is sezed to it and i cant remove it to replace the bearings
01:30 AM sydenkneee: how did u learn ur stuff?
01:31 AM rue_mohr: experience
01:31 AM rue_mohr: unlike the spelling
01:31 AM sydenkneee: so just learning off someone else?
01:31 AM rue_mohr: no, DOING
01:31 AM rue_mohr: the more you DO the more you LEARN
01:32 AM rue_mohr: learn by DOING not talking DOING
01:32 AM sydenkneee: yea but how did you intially learn?
01:32 AM sydenkneee: book?
01:32 AM rue_mohr: a few books for inspiration
01:32 AM sydenkneee: cool
01:32 AM sydenkneee: what's the coolest thing you've built
01:33 AM sydenkneee: like the thing you felt the most proud of
01:33 AM rue_mohr: I'd say a 3d printer, but there are severl things depending on the catagory
01:34 AM sydenkneee: can I ask, where are you in world?
01:34 AM rue_mohr: canada
01:34 AM sydenkneee: nice
01:34 AM sydenkneee: I lived in Banff for 6 months
01:34 AM sydenkneee: can you tell where i'm from? :)
01:35 AM rue_mohr: I dont care
01:35 AM rue_mohr: :)
01:35 AM sydenkneee: what do you care about?
01:35 AM rue_mohr: geez, lots of things, I'm not sure tho
01:36 AM AchiestDragon: the first robot kit i built was one of these while at collage http://www.megadroid.com/images/hero1.jpg that was some time back
01:36 AM sydenkneee: lol that looks crazy
01:36 AM rue_mohr: k, now mke your own start
01:36 AM sydenkneee: what could it do?
01:39 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/arm10/p1080872.jpg
01:39 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/arm9/p1060859.jpg
01:40 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/arm8/p1060648.jpg
01:40 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/arm7/p1060456.jpg
01:40 AM rue_mohr: er, heh no
01:40 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/arm7/p1060364.jpg
01:41 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/arm6/p1070897.jpg that ones still a work in progress
01:42 AM AchiestDragon: these arnt bad as an intro to robotics ,, the rpi is not included ,, there easy enough to get going both software and build for beginneres http://4tronix.co.uk/store/index.php?rt=product/product&product_id=471
01:42 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/arm5/p1030984.jpg <-- 1/4 of my workbench!
01:42 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/arm4/p1060574.jpg
01:43 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/armcontroller/p1070088.jpg
01:43 AM rue_mohr: ever had 4 robot arms all following you at once?
01:43 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/buddy_III/p1020056.jpg
01:44 AM rue_mohr: 1/2 my workbench...
01:44 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/mowerbot2/p1020374.jpg
01:44 AM rue_mohr: maybe next year I'll have a lawn to mow
01:44 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/frankenhex/p1090284.jpg cause ya know, 3d printing... yea
01:46 AM rue_mohr: rue ?
01:46 AM rue_mohr: yes?
01:46 AM rue_mohr: your talking to the wall
01:46 AM rue_mohr: uh, oh?.. damn...
01:46 AM AchiestDragon: no
01:46 AM rue_mohr: who?
01:46 AM AchiestDragon: were all okking at the pics
01:47 AM rue_mohr: hahaha, thanks anyhow
01:47 AM AchiestDragon: okking / looking
01:47 AM rue_mohr: should I point out THAT THE DIRECTORIES ARE BROWSABLE
01:48 AM rue_mohr: if anyone is into URL 'hacking'
01:48 AM mrdata: always
01:48 AM AchiestDragon: dam going to be lost for hours
01:49 AM sydenkneee: omg that looks so advanced
01:49 AM rue_mohr: ?
01:50 AM sydenkneee: your pics
01:50 AM rue_mohr: which ones, its all just playing
01:52 AM rue_mohr: I should also point out that if your lazy, there is a slide.htm in most of them that will play thru all the images for you
01:55 AM sydenkneee: lol i'm not lazy
01:55 AM sydenkneee: I looked at all of them
01:56 AM sydenkneee: the one that ends in 574
02:02 AM rue_mohr: lots of them are build logs, so you can make one too
02:04 AM rue_mohr: its not advanced tho, its all just footprints in a road walked
02:05 AM AchiestDragon: trial and error , till something works
02:06 AM rue_mohr: most of the time it works, and I decide I want to go again with improvements
02:14 AM AchiestDragon: yea , same here ,, all fun and something to do
02:15 AM rue_mohr: I'm hoping that I can get good enough fast enough to save myself
02:15 AM rue_mohr: but I need exponential progress
02:18 AM AchiestDragon: i have to ask , ,do you have any spesific goals you want a robot for
02:21 AM AchiestDragon: i realy want ot make one that is able to self guide autonimously and be able to cope with getting up and down a staircase ,
02:21 AM AchiestDragon: and cope with rough terain
02:22 AM rue_mohr: yes, my current operating platform is cronologically restruicted
02:22 AM rue_mohr: restricted
02:22 AM rue_mohr: sorry, not paying attention
02:24 AM AchiestDragon: np , i thought a hexipod would be good but as it can lift legs high enough to climb , but are genaraly quite wide when you make the legs anything like whats needed
02:25 AM rue_mohr: yes, and the motors are quite weak
02:25 AM AchiestDragon: the starcase here has a width limit of about 1meter and idealy i need it to make its way thoug ha standard 800mm doorway
02:26 AM rue_mohr: which means they need to be kept far in
02:26 AM AchiestDragon: so looking at something allong the lines of the nasa rover that has wheels it can lift to get over things
02:28 AM rue_mohr: pff
02:30 AM AchiestDragon: https://drive.google.com/file/d/1xdgMuFsMyA-zSalo1IKcGLafK79w-ntl/view?usp=sharing first thoughts on it ,, im changing the wheel lift so i can indipendantly lift each wheel not just the front 4
02:31 AM AchiestDragon: the wheels rotate allong z so it can move sidways wihtout turning the main body arround
02:32 AM rue_mohr: I had a bag of 50 alligator clips
02:32 AM rue_mohr: I know I did
02:32 AM anonnumberanon: Getting wen drill press 8 inch asap
02:35 AM anonnumberanon: Gonna make first cnc out of mdf.
02:47 AM AchiestDragon: https://drive.google.com/file/d/1xn7n3geqM86FylT1lIh8mt9RWFy2DHhD/view?usp=sharing this is as far as ive got with the final parts , just thinking how best to do the suspention and wheel arms
02:53 AM anonnumberanon: Rue i already told u need to do more biology if you want to mess with your body.
02:54 AM anonnumberanon: Get rats at least and start experimenting
02:54 AM anonnumberanon: Your next robot should be a surgical robot
02:55 AM AchiestDragon: https://drive.google.com/file/d/1inBYd_lCDijGC_DatgrG3-BN6ZImn1kP/view?usp=sharing head cross section view
02:56 AM rue_shop3: anonnumberanon, did you have a windows machine?
02:56 AM rue_shop3: you got a lot more terain to cover than ya think
02:59 AM AchiestDragon: not mdf ,, mdf goes soft if the machine gets damp fine if you keep it in a heated home but not in a workshop
03:00 AM rue_shop3: you can go from cardboard to steel
03:01 AM rue_shop3: its like pouring gas on a flame tho, too much will just put it out
03:01 AM rue_shop3: so make the cardboard one work first
03:01 AM rue_shop3: or, just throw out what I have to say and do whatever you want, whatever
03:02 AM rue_shop3: 1104612
03:04 AM AchiestDragon: good start point for building your first cnc is to read though the cnczone forum and pick up on the problems others faced with different designs then at least you will have some understanding as to what causes problems and what to look out for
03:06 AM AchiestDragon: i know there is places selling stepper kit and cheap drivers but you will understand after reading the forum why most of those kits are not worth the expence and if you want it to work well you need the ones that do the job as stated
03:07 AM AchiestDragon: that will prob save you 3 years and a quite a bit of $$$ than trying and finding out the hard way
03:08 AM rue_mohr: no
03:08 AM rue_mohr: no reading, no talking, no planning
03:08 AM rue_mohr: DO
03:08 AM rue_mohr: DO lectronics so you know electronics, DO mechnical things so you know whihc damn way a screw turns, DO
03:08 AM rue_mohr: 90% of the things you need to know YOU CANNOT just read, you need to have REAL experience
03:09 AM AchiestDragon: true , but theres a lot you can pick up by learning from others mistakes rather than making them yourself all the time
03:09 AM rue_mohr: ESPECIALLY because of "Picassos brush" which means that ANYTHING you are told is only assured to work FOR THE PERSON WHO TOLD YOU
03:11 AM anonnumberanon: I dont have a windoes machine.
03:12 AM anonnumberanon: I have a pc and a laptop however :)
03:13 AM rue_mohr: anonnumberanon, ok, well, chip away on installing grbl on an arduino
03:13 AM rue_mohr: 1.7 iirc
03:13 AM rue_mohr: er uno
03:13 AM rue_mohr: whatever
03:13 AM AchiestDragon: even thouhg i ususaly find it helps to read them sometimes usualy it just conferms what i found happened anyway , in most cases
03:13 AM rue_mohr: I'm not waying dont read, I'm just saying that its all worthless till you pick tings up and try to do stuff
03:13 AM anonnumberanon: Does it run on an avr instead? Just curious cause idont use arduino too much
03:13 AM rue_mohr: fail fail often, learn from failure
03:14 AM rue_mohr: anonnumberanon, m328
03:14 AM rue_mohr: so, uno, pro mini, whatever
03:14 AM rue_mohr: I grab arduino baords cause they are cheaper than avrs
03:14 AM anonnumberanon: Yeah but there is also the more important (imo) what to buy and not to buy and time vs money.
03:14 AM rue_mohr: you see th funny point int hat right?
03:15 AM rue_mohr: yea, buy an uno, cause the $1.50 they cost is worth less than the time it takes to put it all togethor on a breadboard
03:15 AM AchiestDragon: yea ,, beeing able to understand why something happens is the reason , lerning also involves trying it anyway , but you can make more progress buy seeing what to look for before jumping in with both feet so to speak
03:16 AM rue_mohr: your going to notice something if you look at those things your taking apart too
03:16 AM rue_mohr: your going to notice that in commercial design, almost NEVER does anyone direct drive a system off a stepper
03:17 AM anonnumberanon: You're talking as someone who wants to learn everything. Who got time for that?
03:17 AM AchiestDragon: at the level we are at i often find that most of it is new and theres not much in the way of tried and tested methods anyway , thats why its still fun
03:17 AM anonnumberanon: Pick your battles as they say.
03:18 AM rue_mohr: anonnumberanon, do you have it downloaded?
03:18 AM rue_mohr: cmon, fruitfly, you only gonna live so long.
03:18 AM anonnumberanon: Its 4 am and i have a 2cm^2 hot glue gun burn on my index finger
03:19 AM * rue_mohr smacks head on desk
03:19 AM anonnumberanon: Im not doing anything :)
03:19 AM rue_mohr: see? tings I'd not have thought of, Use of a gluegun
03:19 AM rue_mohr: glue -> part, not glue->finger->part
03:19 AM anonnumberanon: It dried on my finger
03:19 AM * rue_mohr shakes head
03:20 AM anonnumberanon: I went to pull it all out and the skin went with it
03:20 AM rue_mohr: :(
03:21 AM rue_mohr: ===[II]> <-- hot end, dont touch.
03:21 AM rue_mohr: II
03:22 AM rue_mohr: I'm gonna take a 2 hr nap
03:22 AM AchiestDragon: hp inkjet printers ,, they have some nice motors , some linear rails , some optical sensors and a nice liniear optical strip ,, look for 2 a3 modles and 2 a4 moddles and you got the main parts to build a qute good 3d printer x,y and z with at least a 300*300 * 200 print aria with a quick mdf frame
03:23 AM anonnumberanon: It looks like this but only on said skin suface
03:23 AM anonnumberanon: https://www.google.com/search?q=hot+glue+gun+burn&num=30&client=firefox-b&prmd=ivns&source=lnms&tbm=isch&sa=X&ved=0ahUKEwi7hqGFj__XAhVJLSYKHT2HDCsQ_AUIBigB#mhpiv=6&spf=1512897712242
03:23 AM AchiestDragon: alhthoug you will ahve to sort out your own electroincs for servo drive
03:23 AM AchiestDragon: and a 3d print hot end /extruder
03:24 AM rue_bed: he needs to get a stepper motor working first
03:24 AM rue_bed: we need to go over what they look like and how they work
03:24 AM anonnumberanon: No no 3d im making a cnc mill
03:24 AM rue_bed: sure, whatever
03:24 AM rue_bed: same comment
03:25 AM anonnumberanon: Yes but the cnc mill is bootcamp and 3d printer is playground
03:28 AM rue_bed: its the same, it dosn't matter
03:28 AM rue_bed: do you have grbl downloaded?
03:28 AM AchiestDragon: a in at the deep end first sort of guy
03:28 AM anonnumberanon: As for my spec of cutting aluminum with tight tolerances and cut depth of an inch
03:28 AM rue_bed: no
03:28 AM rue_bed: you will need a multi-horsepower motor and a 2" wide bit to handle the stress
03:28 AM rue_bed: its not how ya do things
03:28 AM anonnumberanon: Thers no such thing
03:28 AM anonnumberanon: As 2"
03:28 AM anonnumberanon: Lol
03:28 AM rue_bed: there are, and there are larger
03:28 AM anonnumberanon: Not in this context
03:30 AM anonnumberanon: But you must use liquid cooling and lubricant.
03:30 AM anonnumberanon: As a first.
03:30 AM rue_bed: I'v got a 1/8" bit doing 0.25mm passes thru aluminum at, I think, 12mm/min right now
03:31 AM rue_bed: yea, thats a whole mess unto itself
03:31 AM anonnumberanon: Also you use a 1 1/4 hp router at 20k rpm
03:31 AM rue_bed: you have to have the machine designed for it
03:31 AM rue_bed: maybe you should work on making a stepper motor turn first
03:31 AM rue_bed: and have grbl installed on a m328
03:31 AM anonnumberanon: Thats easy
03:32 AM rue_bed: no, no you failed
03:32 AM anonnumberanon: I read the arduino stepper lib
03:32 AM rue_bed: technically 2.5 hours ago
03:32 AM anonnumberanon: Not much to it compared to wbat iv done to drive servos in C and asm
03:32 AM rue_bed: sure, but ya failed, you need to learn more before you close to making a cnc
03:33 AM * rue_bed points at the clock
03:33 AM rue_bed: we learned what you dont know
03:33 AM rue_bed: which is more than I thought
03:33 AM rue_bed: I look forward to helping you learn about steppers and suck
03:33 AM rue_bed: such
03:33 AM rue_bed: hah
03:34 AM anonnumberanon: Ok
03:34 AM rue_bed: do you have a m328 to put grbl on?
03:34 AM anonnumberanon: Good
03:34 AM anonnumberanon: Yeah
03:34 AM AchiestDragon: anonnumberanon: in machineinging industry this is the sort of machine that would give the nice heavy cuts your on about in practial terms small proper built mills can just about manage 10mm wide and 1/2 a mm deep cuts off each pass
03:34 AM AchiestDragon: https://www.youtube.com/watch?v=96ahE6q_0Gk
03:34 AM rue_bed: then would ya do that, I need your list of questions about how to do it
03:35 AM anonnumberanon: I found a hack Achiest
03:36 AM anonnumberanon: Look here
03:36 AM anonnumberanon: https://m.youtube.com/watch?v=Lunou93re9g
03:38 AM anonnumberanon: I wont be making many of a single part only oneoffs so i can go slow, very shallow cuts.
03:38 AM anonnumberanon: Rue what grbl?
03:38 AM rue_bed: 1.7
03:38 AM rue_bed: I suppose thats the first answer
03:38 AM anonnumberanon: Want list of questions on that?
03:38 AM anonnumberanon: Lol
03:38 AM rue_bed: sorta, I'm going to sleep
03:39 AM rue_bed: dont get me wrong, I AM in bed
03:39 AM AchiestDragon: rue_bed: you have wakeup on lan ?
03:39 AM rue_bed: haha, NO
03:39 AM AchiestDragon: nn
03:42 AM rue_bed: I'm looking up op-amp implementations of PID controllers, help me think thru a better digital implementation
03:42 AM AchiestDragon: another 3" of snow here overnight , and still snowing
03:43 AM anonnumberanon: First question (and last for tonight), why should i use garble on an avr and then have to make more electronics when i can just use the parallel board by Sainsmart connected to a computer running linuxcnc (plus a power driver board for each stepper)?
03:43 AM rue_bed: ok
03:43 AM rue_bed: because grbl is faster
03:43 AM rue_bed: grbl will get you going faster
03:43 AM rue_bed: and its done for you, canned solution for a starter
03:44 AM anonnumberanon: Ah yeah but i will reach its limits even faster
03:44 AM anonnumberanon: Wont i?
03:44 AM rue_bed: there are good reasons to go with linuxcnc, none of them involve a parallel port
03:44 AM rue_bed: no, I use grbl
03:44 AM rue_bed: on 2 of my 3 machines
03:44 AM anonnumberanon: I was trying to help u identify the board
03:44 AM rue_bed: and I'm converting the 3rd
03:45 AM anonnumberanon: Also this is an indication that i know that the usb ones seemingly many people use are crap because they dont act real time and have high latency
03:45 AM AchiestDragon: there was also a lot of talk about using parralell printer port driven stepper drivers as the stepping rates are limited to the rate of the port and also you need a rt version of linux installed rt as in real time
03:46 AM rue_bed: the parallel port is slower than the m328
03:46 AM rue_bed: use grbl
03:46 AM rue_bed: unless you have the $700 in hardware like tom does
03:46 AM anonnumberanon: Brb going to store
03:47 AM anonnumberanon: Interesting talk tho
03:47 AM AchiestDragon: its beein some time since i looked but there was talk of using a fpga/clpd based controler as that lifted the timing constraints and allows you do machine true circles with less jitter and quicker
03:47 AM rue_bed: get some skin for your finger
03:47 AM rue_bed: AchiestDragon, thats the $700 in hardware that tom has
03:47 AM anonnumberanon: Haha now thats crazy
03:48 AM anonnumberanon: Although avr or stm32 would most likely rival an fpga
03:48 AM rue_bed: option a) $1.50 arduino option b) $700 in fpga + linuxcnc
03:48 AM anonnumberanon: I mean fpga is not instant
03:49 AM AchiestDragon: yea , even the 3d printers use a microcontoler as the microcontroler i/o is faster than a pc ,, but still nothing like as fast fpga/cpld
03:49 AM anonnumberanon: I just want the nice linuxcnc app on my pc
03:49 AM rue_bed: no they have atleast 4ns latency
03:49 AM rue_bed: anonnumberanon, "use grbl"
03:50 AM rue_bed: on ALL the internet google knows, I'
03:51 AM rue_bed: v only found _1_ analog PID schematic thats real
03:51 AM rue_bed: aka, not just an academic example
03:51 AM AchiestDragon: https://drive.google.com/file/d/1Grt1KDSx6hd58fnzcQ344fNHQyIeqf2m/view?usp=sharing < 3d printer stepper drivers although this config would suit a router also
03:51 AM rue_bed: those toroids are nice
03:52 AM rue_bed: I have a few, love the ratings
03:52 AM rue_bed: probably overkill cause of the constant power converters in the motor drivers
03:53 AM AchiestDragon: the small toroid poweres the steppers , the big one is for the heated bed 24-0-24 at 10A on that
03:54 AM rue_bed: YES someone NOT using a carefully regulated supply for a HEATER
03:55 AM weyland|yutani: rue_bed, if i had known that my company threw like 10 to scrapmetal relly big ones for used for lighting back in the days
03:55 AM AchiestDragon: the heater is just resistive wire taped to the underside of a 700mm*350mm*5mm bit of stainless steel plate
03:56 AM AchiestDragon: worked till it burned out the octal relay and its base
03:57 AM AchiestDragon: althoug hit did take all of 45 mins to get up to temp
03:58 AM AchiestDragon: arrgg dam space before h again althoug hit / although it
04:02 AM AchiestDragon: my cats lurking about the house sulking as its snowing outside , beeing black she cant hide in the snow and sneek up unnoticed
04:11 AM rue_bed: how did you keep the stainless form shorting the element?
04:12 AM AchiestDragon: a layer of tape , wire then more tape
04:12 AM rue_bed: musta been some wickid tape
04:13 AM AchiestDragon: using that high temp tape designed for holding heated wire in place ,, i used 2 full rolls of the dam stuff and it was like £5 a roll
04:14 AM AchiestDragon: does the job though , and its still stuck in place not falling off 5 years later
04:16 AM anonnumberanon: Fine ill watch the infamous cnc + grbl Youtube vidéo
04:17 AM anonnumberanon: Ill get the duino out of storage when i wake up
04:18 AM AchiestDragon: https://www.ebay.co.uk/itm/5cm-High-Temperature-Heat-Resistant-Polymide-Car-Trim-Strong-Adhesive-Tape/132036461928? this sort of tape
04:22 AM AchiestDragon: although some mylar stuff , as often used on heating ducts and is good to 240c constant use 300c peek
04:25 AM anonnumberanon: Ok the description of grbl in the wiki makes it quite interesting. No G code however, to note.
04:26 AM AchiestDragon: and some Nichrome Wire layed out like the element on an electric blanket i used 4 seperate "loops " wiered in parralell to get the resistance right for the lenths used
04:30 AM AchiestDragon: have a 3 phase 40A din rail contactor that i should use to replace that octal relay , just that i have to dismantle the whole machine to get it out of the room its in so i can work on it as theres no room to work on it were it is , and thats not going to happen for some time
04:32 AM AchiestDragon: ie dismantle it , reaseemble it in here , fix it , then dismantle it again and reasemble it back were it is or more likely now it will end up somware else
04:34 AM AchiestDragon: and no rush anymore as i have a tevo delta on its way from china
04:40 AM anonnumberanon: What machine?
04:43 AM AchiestDragon: https://www.youtube.com/watch?v=HD0z1_UE3i4
04:48 AM AchiestDragon: it should sit and look quite th part in the house rather than the one i built that looks like it was thown together by a bulldoser , and if using pla not be a prob for fumes , when i get arround to fixing the one i have then it will prob be used for abs and nylon , but also should up the controler to a new 32bit one at the same time , may even fit a multi extruder to it
04:51 AM AchiestDragon: i had even thought of strapping the mig welder to it and getting it to do 3d metal weld printing but would have to look at what to do about the bed for doing that
04:53 AM AchiestDragon: the thought of trying to seperate the part from the bed with a angle grinder or hack saw does sort of put a damper on that
05:23 AM anonnumberanon: Haha
05:25 AM anonnumberanon: Oh that printer is big
06:04 AM AchiestDragon: yea big enoug to print all the "bone" sized peaces to build a humaniod robot full size , with exception of the hip and ribs that would need to be printed in 2 halves
06:06 AM AchiestDragon: the one i made has a 600* 300*300 mm max print aria , the tevo a 340dia by 500 mm max print aria so not far from it
06:12 AM AchiestDragon: the tevo looks quite compact compared to this https://drive.google.com/file/d/1WFquJXt9Y46myXbNoDi4nfmDVwrtaEIE/view?usp=sharing
06:16 AM AchiestDragon: shown here with full size cat for scale https://drive.google.com/file/d/1Gk61w-GKZfc0KHBE9gm9AwuGZ4zuJ85E/view
06:56 AM AchiestDragon: friend up the road from me built this https://drive.google.com/file/d/1D3BXToQt_hJE1UJ1ka74PTC_VofqA7pc/view?usp=sharing good for giving his other half cooking instructions like "eggs sturr my mate "
06:58 AM AchiestDragon: https://drive.google.com/file/d/1D3BXToQt_hJE1UJ1ka74PTC_VofqA7pc/view?usp=sharing
07:03 AM AchiestDragon: https://drive.google.com/file/d/11Xce7coiSzb6NmFkQLM1Q2O9EqfNxxo8/view?usp=sharing rather video of it if it plays
10:41 AM rue_bed: anonnumberanon, ok, did you get grbl loaded on a m328
10:41 AM rue_bed: ?
10:41 AM rue_bed: it takes standard gcode, there is a list of the subset implemented on it
10:42 AM Tom_L: i can see why i've never owned an apple product
10:42 AM rue_bed: heh
10:43 AM Tom_L: needed a program only available on ios so forced...
10:43 AM rue_bed: "apple dosn't support your desire to do that, so forget it"
10:43 AM Tom_L: this is all it will be used for
10:43 AM rue_bed: and everyone is getting all account centrick
10:44 AM Tom_L: did you see the latest pics?
10:44 AM Tom_L: can't remember...
10:44 AM rue_bed: and every account requires a stupid amount of hoops to prove your a real human
10:44 AM rue_bed: an inhumane amount really.
10:44 AM Tom_L: what gripes me is you have to have an itune act
10:44 AM Tom_L: i could give a shit less about itunes
10:45 AM rue_bed: for pc yea
10:45 AM rue_bed: yea
10:45 AM Tom_L: taking an eternity to update the os
10:49 AM rue_bed: and just think, you have 10x the patience of the youngen's
10:50 AM rue_bed: I'm awake, and kinda borred, gonna go make some christmas lights
10:50 AM Tom_L: they probably throw it out and get a new one
10:52 AM rue_mohr: correct
10:52 AM rue_mohr: "dad, we need a new car, the old one got a flat tire so I threw it out"
11:56 AM rue_shop3: EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE I'm almost out of 150 ohm resistors
11:57 AM rue_shop3: oooh struck down in the... ALIEXPRESS!!!
11:58 AM rue_shop3: oooh geeez, I dunno, arg, expensive....
11:58 AM rue_shop3: were talking like almost $7.20 for 1000pcs
11:58 AM rue_shop3: OOOH wait, thats cad...
11:59 AM anonnumberanon: I did an inventory of my chips and supporting gear
12:01 PM anonnumberanon: Got 2 pro minis unprepared, an attiny45, a 328pdip on a breadboard
12:02 PM anonnumberanon: Gonna try to source an uno dev board around me if i can pick up
12:02 PM rue_shop3: do the pro mini
12:02 PM anonnumberanon: If not ill solder those headers on one of the minis and use that
12:03 PM anonnumberanon: I dont know how i lost that uno i want it back its nice to throw in backpack
12:05 PM rue_shop3: I'd like to point out that in the real world, the I beam I got is smaller, its 2-3/4" x 4"
12:05 PM anonnumberanon: And 7 nrf24l01+, ready for further messing with
12:05 PM rue_shop3: (for my cnc upright
12:05 PM rue_shop3: )
12:05 PM rue_shop3: uno or pro mini dosn't matter I want you to have hardware to talk to, even if its not connected to anything
12:05 PM anonnumberanon: I dont like something about it though, its weird double header io that cant be used on breadboard
12:08 PM rue_shop3: ignore th extra pins
12:08 PM rue_shop3: just use the two side ones, but more than that, dont worry about it
12:08 PM rue_shop3: just set up the serial interface so you can talk to it
12:09 PM anonnumberanon: Nrf24l01 rue
12:09 PM rue_shop3: no
12:09 PM rue_shop3: put it away
12:09 PM rue_shop3: use serial, I dont want to have you messing with serial debugging while were trying to get groundwork stuff established
12:10 PM rue_shop3: er, with network debugging
12:10 PM * rue_shop3 is resistor shopping
12:10 PM rue_shop3: $10 for 1% or $4 for 5%?
12:12 PM anonnumberanon: Ah that what i would have needed back then would have saved me probably 10 hours
12:12 PM anonnumberanon: https://www.amazon.com/gp/aw/d/B01N5AK6E1/ref=mp_s_a_1_18?ie=UTF8&qid=1512929452&sr=8-18&pi=AC_SX236_SY340_QL65&keywords=nrf24l01&dpPl=1&dpID=51xCpU4VnSL&ref=plSrch
12:12 PM anonnumberanon: No man im no playing with nrf today
12:12 PM anonnumberanon: Its not priority
12:13 PM anonnumberanon: Even if fun af
12:13 PM anonnumberanon: :)
12:14 PM rue_shop3: maybe 500 is enough?
12:17 PM anonnumberanon: Is this what u use the most?
12:18 PM anonnumberanon: Are u still trying to fill ur 100dollar gift card?
12:23 PM anonnumberanon: Ok my burn was only .75 cm^2
12:33 PM anonnumberanon: http://ibb.co/mu31eb
12:33 PM anonnumberanon: The white is from the bandaid keeping skin wet moist
01:55 PM rue_mohr: yes, hot glue is hot
01:55 PM rue_mohr: so is the pointy end of the hot glue gun
01:56 PM rue_mohr: anonnumberanon, yea grbl did you get it installed?
01:56 PM rue_mohr: any of those craigslist links pay off?
02:45 PM anonnumberanon: At Microcenter. Shopping and gonna pick up an uno and geek out.
02:47 PM rue_mohr: dont pay more than $2
02:48 PM rue_mohr: you already have the pro mini and can use that till you have a machine to operate on
02:59 PM rue_mohr: your gonna spend an extra $8 on something you dont need now anyhow aren't ya?
03:05 PM anonnumberanon: Yes
03:05 PM anonnumberanon: Man Microcenter is like im 8 yo at Toys R Us
03:05 PM rue_mohr: not familier, they ahve stepper motors?
04:43 PM rue_mohr: #define microDiff(A,B) (A==B)?0:(A>B)?(1):(-1)
04:43 PM rue_mohr: this will be amazingly powerfull
04:43 PM rue_mohr: It think
04:59 PM rue_mohr: fail, NEXT
05:04 PM rue_mohr: if the sign is all that matters, I dont get why it dosn't work
05:07 PM anonnumberanon: I got a stepper. Driving back. Over an out.
05:10 PM rue_mohr: I can be optomistic if I keep in mind there IS atleast a cart and horse
05:46 PM Tom_L: ok, i should go form some metal
05:47 PM AchiestDragon: i should stop myself searching ebay
05:47 PM Tom_L: never
05:57 PM AchiestDragon: arrrrg its so adictive ,,, you buy one item and endup staying most a day waiting for the delivery you end up surfing ebay and buying something else , that you end up wating in all day for ....
05:59 PM AchiestDragon: i may not be able to leave the house untill the 18th as it is at this rate
05:59 PM rue_mohr: try a 1 week - 7 months(canada post) from aliexpress
05:59 PM rue_mohr: 50% more stuff for your money, typically
06:00 PM rue_mohr: so the dot product is + if your two vectors are in the same direction
06:00 PM rue_mohr: aka, if one angle is more than 90* of your heading, its negitive
06:01 PM rue_mohr: so, the cross product...
06:01 PM rue_mohr: I think goes + and - depending if your on the left or right of your heading
06:03 PM rue_mohr: I'm gonna lose it if I see much more matrix math
06:09 PM rue_mohr: yup, ok
06:09 PM rue_mohr: Iget it, what stupid names
06:10 PM rue_mohr: the dot product says if its in a conflicting direction or not, the cross product says if its on the left or right
06:10 PM rue_mohr: ok!
06:12 PM Tom_L: yeah what he said...
06:14 PM rue_mohr: ... jsut odnt ask me for the 3d translation
06:14 PM rue_mohr: I know cross product tells you which direction is 90 to a plane
06:20 PM anonnumberanon: So which one? http://ibb.co/gjsEzb
06:22 PM rue_mohr: wtf
06:22 PM rue_mohr: why is there an uno in a package that says pro mini?!?!
06:22 PM rue_mohr: ooh god $8 you could have just used whatyou had and got one comming form chinaaaaaaaa
06:23 PM rue_mohr: does the stepper have any specs?
06:23 PM rue_mohr: its 4 wire sin't it?
06:24 PM rue_mohr: more to be said, that uno is a knockoff that is only origional schematic, wtf, tahts just evil to say
06:24 PM rue_mohr: its a flipping $2 board for $8 arg
06:24 PM * rue_mohr beats head on desk
06:24 PM anonnumberanon: An Uno dev board is beast mode though.
06:25 PM * rue_mohr whines out with his face planted in the desktop..."tell me you didn't pay $20 for the stepper...."
06:26 PM anonnumberanon: And i wondered why they said that too. On the back it says you need and ftdi to use it but i dont think its true
06:26 PM rue_mohr: its a fuckup, thats an uno, not a pro mini
06:26 PM rue_mohr: you dont need a converter for an uno
06:26 PM anonnumberanon: The "Uno" version was $10 .
06:27 PM rue_mohr: wow, ok, atleast they are selling them
06:27 PM rue_mohr: I have to drive for half a day to get anywhere that sells stuff
06:27 PM rue_mohr: and take a ferry
06:27 PM rue_mohr: anyhow
06:27 PM anonnumberanon: I drove 45 min
06:27 PM anonnumberanon: Was an okay drive.
06:27 PM rue_mohr: you..... didn't.... pay....like.....$20 for the stepper..... did... you?????,.....
06:28 PM * orlock walks to the bin
06:28 PM * orlock gets as many steppers as he can carry, fails to do anything with them
06:28 PM orlock: Apparently Nema23's have 608 bearings in them though?
06:28 PM anonnumberanon: Didnt expect to see 3d printers. There were a few steppers by the 3d printer so I took the plunge :)
06:29 PM rue_mohr: :| it was $20 wasn't it?
06:29 PM anonnumberanon: I wont say my dude.
06:29 PM * rue_mohr beats head on desk
06:30 PM * orlock lays down some padding
06:30 PM rue_mohr: well, on the upside, the odds of you screwing it up are low
06:30 PM rue_mohr: ok, load grbl on your pro mini uno there...
06:30 PM * rue_mohr shakes head
06:30 PM anonnumberanon: You missed the crucial step, actually answering my queation...
06:31 PM rue_mohr: orlock, should I tell him he should have spent the $4 on the A4988 driver too?
06:31 PM rue_mohr: oops
06:31 PM anonnumberanon: Should we call it the Arduino Promunio?
06:31 PM rue_mohr: hah, sure
06:31 PM rue_mohr: its as f****d up as everything arduino
06:32 PM orlock: At least i don;t get requests from people to put their arduino's on the LAN
06:32 PM orlock: unlike rpi''s
06:32 PM anonnumberanon: Lol
06:32 PM rue_mohr: ... I did it
06:32 PM rue_mohr: uno web server
06:32 PM rue_mohr: :D
06:33 PM orlock: :)
06:33 PM anonnumberanon: So Debiantryhard or Windoesnot?
06:34 PM rue_mohr: debian is fine
06:34 PM anonnumberanon: Iv been waiting to load a frigging OS this entire time.
06:34 PM rue_mohr: I dont have an NC processor for linux, the only descent one I can find is eval windows only
06:34 PM anonnumberanon: What is NC processor?
06:35 PM rue_mohr: makes the file that the machine uses to make your part
06:35 PM orlock: NC?
06:35 PM rue_mohr: bCNC makes files, but its a horrid program
06:35 PM orlock: oh
06:35 PM orlock: a toolpath generator?
06:35 PM rue_mohr: sure
06:36 PM AchiestDragon: NC numeric control
06:36 PM orlock: rue_mohr: apparently the good ones are really really fucking expensive?
06:36 PM anonnumberanon: ooh Linux feels so warm and fuzzy I'd been away from it for a couple weeks
06:37 PM anonnumberanon: ok, not in repo
06:37 PM anonnumberanon: let's see
06:37 PM orlock: rue_mohr: cant you just .. invert the model annd stick it into slic3r?
06:37 PM anonnumberanon: is it an arduino thing or avr?
06:37 PM rue_mohr: I been using bamcam .. or cambam, its descent, but only 30 uses, so I never close it
06:37 PM orlock: instead of extruding the model
06:37 PM orlock: chip away what's _not_ the model?
06:38 PM rue_mohr: anonnumberanon, no, you didn't download it yesterday?
06:38 PM anonnumberanon: i was on my phone m8
06:38 PM anonnumberanon: i only read the intro wiki
06:38 PM rue_mohr: ok, goal, by friday, have grbl installed on that uno and be able to talk to it
06:39 PM rue_mohr: lets push the bar and say by next friday
06:40 PM rue_mohr: the 15th'
06:40 PM anonnumberanon: ok you said version 17?
06:40 PM rue_mohr: 2017
06:40 PM rue_mohr: 1.7
06:40 PM anonnumberanon: cause i see here the newest version is 1.1
06:40 PM rue_mohr: is the last mae version iirc
06:40 PM AchiestDragon: orlock: no theres more to it than that for cnc ,, slic3r is good for 3d printing stl to gcode but nort ment for tool paths for cnc milling
06:41 PM anonnumberanon: can you check rue, this is wierd
06:41 PM anonnumberanon: here i show v1.1
06:41 PM anonnumberanon: https://github.com/gnea/grbl
06:41 PM rue_mohr: anonnumberanon, you might be right, looks like I might be using 0.9j
06:42 PM anonnumberanon: ok
06:42 PM rue_mohr: so ok
06:43 PM anonnumberanon: looks like no tengo la arduino ide on this OS
06:43 PM rue_mohr: you have to download it from bla and install
07:05 PM anonnumberanon: ok checked that it is actually an Uno, it is
07:05 PM anonnumberanon: i flashed a patrician-customized version of Blink to it
07:05 PM anonnumberanon: blinks every 2 seconds, only for 50 miliseconds, i bet that makes me a Duinomaster!!
07:06 PM anonnumberanon: actually i had never bought an uno before
07:07 PM anonnumberanon: used them a bunch but they belonged to my uni, had 4 of them in my posession at one time, even when we were building the quadcopter
07:07 PM anonnumberanon: now i bought one, it feels special
07:10 PM anonnumberanon: i couldn't find any driver boards though
07:10 PM anonnumberanon: don't know if i have the chips to make one
07:10 PM anonnumberanon: not sure what chips a driver board takes yet
07:10 PM anonnumberanon: importing grbl...
07:14 PM rue_mohr: if you want to make your own driver, you want a 5+ wire stepper
07:15 PM rue_mohr: the driver baords are cheap, but we can most likley hack one from the other printers you get with steppers in them
07:15 PM orlock: rue: I'll get a photo of this stepper driver board for you in a bit
07:16 PM orlock: Its the one that drives a 4 wire and a 6 wire stepper, both with the same spec's though
07:16 PM orlock: Apparently it's got some low power mode?
07:16 PM rue_mohr: its the suck mode yea
07:16 PM rue_mohr: :)
07:17 PM orlock: Its with me at work currently so i can probe it in one of the hardware labs
07:17 PM orlock: (as opposed to one of the wet labs....)
07:27 PM anonnumberanon: "done uploading"
07:27 PM anonnumberanon: however, see: "Binary sketch size: 31,332 bytes (of a 32,256 byte maximum)"
07:27 PM anonnumberanon: lol
07:34 PM anonnumberanon: ok i spoke too soon about that 31,332 is less than 32,256
07:37 PM SpeedEvil: It's OK, some people find complex maths hard.
07:39 PM rue_mohr: anonnumberanon, ok, so, if you connect, it should say "grbl v1.0" or whatever
07:39 PM rue_mohr: grbl has a lot fo junk in it and just barely fits int eh avr
07:40 PM rue_mohr: but hey, I dont have time to rewrite it
07:42 PM anonnumberanon: uhm seems like good junk though, they're really maximizing the avr with it!
07:42 PM rue_mohr: sure
07:42 PM rue_mohr: can you connect to it?
07:42 PM rue_mohr: have it tell you its alive?
07:43 PM anonnumberanon: unless you consider the fact that they claim they could rewrite it to add this path algorithm thingy on top of what they already have
07:43 PM anonnumberanon: yeah ill try
07:43 PM rue_mohr: they like to use 115200 baud, which is dumb, its a machine that cant execute instructions 1/100 the speed they can be sent
07:43 PM rue_mohr: so i suggest dialing it down to 9600
07:44 PM rue_mohr: which the avrs clock rate can match properly, unlike 115200 which its off
07:44 PM anonnumberanon: yeah it redas it, 9600 is too low it wont work, only 115k
07:44 PM anonnumberanon: well i could try lower
07:44 PM rue_mohr: you need to modify the settings file
07:44 PM rue_mohr: settings.h or soemthing
07:45 PM rue_mohr: there will be less comm errs at 9600
07:45 PM rue_mohr: iirc 119200 is the highest rate at which the avr can properly do
07:45 PM rue_mohr: er 19200
07:46 PM rue_mohr: 9600 has no problem keeping the avrs buffer full
07:47 PM rue_mohr: tell me when you have a terminal, dont worry about the baud rate now
07:47 PM anonnumberanon: ok
07:47 PM anonnumberanon: hang on
07:47 PM anonnumberanon: i was trying a 56k and everything bugged gotta fix
07:48 PM rue_mohr: you avhe to modify settings.h recompile, and reupload
07:49 PM anonnumberanon: ok no no need
07:49 PM anonnumberanon: i can use 115k
07:49 PM rue_mohr: dont use 115k with the machine
07:49 PM rue_mohr: doyou know why?
07:49 PM anonnumberanon: ok actually lets change it now then
07:49 PM rue_mohr: its fine for esting now
07:49 PM rue_mohr: meh ok
07:49 PM anonnumberanon: well it would increase latency?
07:49 PM rue_mohr: no
07:49 PM rue_mohr: grbl keep a buffer
07:50 PM rue_mohr: the average command takes between .25 to 60 secoonds to perform
07:50 PM rue_mohr: lots of time for 960 characters/sec to refill the buffer
07:50 PM rue_mohr: buffer usually stores about 10 commands
07:52 PM anonnumberanon: change this line?
07:52 PM anonnumberanon: #define BAUD_RATE 115200
07:52 PM rue_mohr: the reason is that 115k baud is wrong by 5%
07:52 PM rue_mohr: yes, change to 9600
07:55 PM anonnumberanon: serial connection up and running at 9600
07:55 PM rue_mohr: k
07:55 PM rue_mohr: it says "grbl 1.0" or whatever?
07:56 PM anonnumberanon: yeah. i tried sending $ to get help, no response
07:56 PM rue_mohr: no, send ?
07:56 PM rue_mohr: it should give you a status
07:56 PM anonnumberanon: yeah yeah i got the status
07:56 PM anonnumberanon: Grbl 1.1f ['$' for help]
07:57 PM rue_mohr: k
07:57 PM rue_mohr: and ?
07:57 PM anonnumberanon: thats it
07:57 PM rue_mohr: oooh your end of line is wrong
07:57 PM rue_mohr: or did that work?
07:57 PM anonnumberanon: i have no line ending
07:57 PM anonnumberanon: no, '$' does not do anything
07:57 PM rue_mohr: yea, it needs one of cr or nl, I cant remember
07:57 PM anonnumberanon: i sent a new line and now get "error:3"
07:57 PM rue_mohr: cool
07:58 PM rue_mohr: question mark and newline
07:58 PM anonnumberanon: okay, it was carrage return
07:58 PM rue_mohr: k
07:58 PM rue_mohr: see the unexpected challanges?
07:58 PM anonnumberanon: so far it's been really easy
07:58 PM anonnumberanon: the challenge i see is making an H bridge :)
07:59 PM rue_mohr: two of them,
07:59 PM anonnumberanon: i kiss myself right now for ordering an assorment of transistors
07:59 PM anonnumberanon: and heavy ones too
07:59 PM rue_mohr: ok try this
08:00 PM anonnumberanon: if that is the only exotic IC this will take
08:00 PM rue_mohr: anonnumberanon, it also has to be multilevel current control
08:00 PM anonnumberanon: saw them in my stash when i did my inventory this morning
08:00 PM anonnumberanon: uhm okay...
08:00 PM anonnumberanon: not familiar with that concept
08:00 PM rue_mohr: try this,
08:00 PM rue_mohr: G00 X10
08:00 PM rue_mohr: it should throw an alarm
08:01 PM anonnumberanon: says "ok"
08:01 PM rue_mohr: huh
08:01 PM rue_mohr: how about G01 X-100
08:03 PM rue_mohr: ?
08:03 PM rue_mohr: no alarm?
08:04 PM rue_mohr: usually they dont want to move untill they have done a homing cycle
08:04 PM rue_mohr: anonnumberanon, where did you go to, what are you up to?
08:06 PM anonnumberanon: oh i was just reading up
08:06 PM anonnumberanon: on the circuit
08:06 PM rue_mohr: dont bother...
08:06 PM anonnumberanon: error:22 on that last command
08:06 PM rue_mohr: that is a 3V motor, dont push 12 or 5V into it or you will burn out a coil
08:06 PM rue_mohr: 22?
08:06 PM rue_mohr: hmm
08:07 PM anonnumberanon: i have an adjustable smps
08:07 PM rue_mohr: no
08:07 PM anonnumberanon: good for 5 amps
08:07 PM rue_mohr: they aren't voltage motor
08:07 PM rue_mohr: they are constant current motors
08:09 PM rue_mohr: thats why you need a variable current bipolar driver
08:09 PM anonnumberanon: i wonder if i have that chip actually
08:09 PM rue_mohr: aka just buy the damn chip

08:13 PM rue_mohr: consider that
08:14 PM anonnumberanon: why is your aliespress in spanish?
08:14 PM rue_mohr: it guessed your default language wrong
08:15 PM anonnumberanon: stf is wrong with you
08:15 PM rue_mohr: youc an change the lauguage
08:15 PM anonnumberanon: i can tell if you've never watched any of my videos :(
08:15 PM anonnumberanon: it's okay i know you're a busy man
08:17 PM anonnumberanon: what about this one

08:17 PM anonnumberanon: wtf
08:17 PM rue_mohr: you ony copy up to the .html
08:17 PM rue_mohr: do not buy that driver
08:18 PM anonnumberanon: https://goo.gl/fgwmLu
08:18 PM rue_mohr: its useless toyou right now
08:18 PM anonnumberanon: incompatible with grbl?
08:18 PM rue_mohr: no, but its useless to you right now, like the stepper you got without a DRIver.....
08:19 PM rue_mohr: you can buy it later
08:20 PM anonnumberanon: like in 2 months?
08:20 PM anonnumberanon: yeah no
08:21 PM anonnumberanon: so let's see about that error message
08:21 PM rue_mohr: it;ll be a motion range error
08:21 PM Tom_L: ok, not much done tonight
08:21 PM Tom_L: alot of sanding paint off steel
08:23 PM rue_mohr: anonnumberanon, ok, so, lets take a direction,
08:23 PM * rue_mohr covers his face, install bcnc
08:26 PM rue_mohr: say when
08:28 PM Tom_itx: when?
08:28 PM Tholia2 is now known as Tholia
08:33 PM anonnumberanon: Tom_itx, share pics of sanded frame :>
08:46 PM rue_mohr: oh speaking of
08:55 PM rue_mohr: damnit where is the number I posted
08:57 PM rue_shop3: 1104612
08:57 PM rue_shop3: 1104612
08:57 PM rue_shop3: 1104612
08:57 PM rue_shop3: 1104612
08:57 PM rue_shop3: 1104612
08:57 PM rue_shop3: 1104612
08:57 PM rue_shop3: 1104612
08:57 PM rue_shop3: 1104612
08:57 PM rue_shop3: 1104612
08:57 PM rue_shop3: 1104612
08:57 PM rue_shop3: 1104612
08:57 PM rue_shop3: there cant miss it now
08:58 PM anonnumberanon: yea what is that
09:02 PM z64555: looks like a chip number
09:03 PM rue_mohr: thingverse number
09:04 PM anonnumberanon: rue_mohr, ok installed
09:04 PM anonnumberanon: running
09:04 PM anonnumberanon: not connected to the avr
09:14 PM rue_mohr: its an evil program
09:15 PM rue_mohr: the main thing wrong with it is that all the stuff you do, generates output without the ability to backtrack to make corrections or changes
09:16 PM rue_mohr: cambam is better, you create an operation profile that it compiles, you can change the details and recompile
09:16 PM rue_mohr: But if you dont have a windows machine (will it run under wine? I dont knwo) that options out
09:20 PM anonnumberanon: remember when I asked you which OS I should run?
09:22 PM rue_mohr: na still not worth widnows
09:23 PM anonnumberanon: can you explain more about not being able to make changes?
09:23 PM anonnumberanon: with the first software
09:23 PM rue_mohr: imagine that your writing C code
09:23 PM rue_mohr: but on a program that compiles every line as you type it, and then throws away what you typed
09:23 PM rue_mohr: thats bcnc
09:24 PM rue_mohr: when you want to change something, all you have to work with is a binary
09:24 PM Tom_L: anonnumberanon i didn't take any pics tonight
09:26 PM anonnumberanon: so it works line by line?
09:28 PM anonnumberanon: cambam is non-free software
09:30 PM rue_mohr: after the first 30 uses
09:30 PM rue_mohr: so dont ever close it
09:30 PM z64555: lol.
09:30 PM rue_mohr: anonnumberanon, so bcnc compiles your operations as you go
09:30 PM rue_mohr: cambam just builds a source file you can change the details of
09:30 PM rue_mohr: sorry, stuff going on here
09:30 PM rue_mohr: supper burning and all
09:31 PM anonnumberanon: gonna fix me some grub
09:31 PM rue_mohr: but bcnc will allow you to draw a circle, engrave it, and send it to grbl
09:32 PM Tom_L: supper burning?
09:32 PM Tom_L: that's kindof a normal event isn't it?
09:32 PM anonnumberanon: so let's do a 101
09:33 PM rue_mohr: no just regular burning, which is normal
09:33 PM anonnumberanon: grbl takes as input g-code, correct?
09:33 PM Tom_L: rue_mohr
09:33 PM Tom_L: did you cut your channel today?
09:33 PM Tom_L: the 15' one
09:34 PM rue_mohr: typically, you design the part in one program -> 2nd program converts to machine commands -> 3rd program spools to machine -> firmware on machine moves motors
09:34 PM rue_mohr: Tom_L, god I completely forgot
09:34 PM Tom_L: did you know solidworks does 3d output?
09:34 PM rue_mohr: I know most programs now do everything
09:34 PM rue_mohr: not my point
09:34 PM Tom_L: i just realized that a while back
09:35 PM Tom_L: the older versions didn't do that
09:35 PM rue_mohr: I keep all the short material in the frame of the bandsaw, so it'll be a task to move it
09:35 PM rue_mohr: esp cause there is a vert bandsaw in the way of moving it
09:36 PM Tom_L: all you need is an extension cord and a angle grinder with a cutoff wheel
09:36 PM Tom_L: i'm getting pretty good with one
09:37 PM Tom_L: i can tell you this... i'm gonna need more room when it comes time to weld it together
09:39 PM rue_mohr: you CAN cut with a stick welder ya know
09:39 PM rue_mohr: you can drill too
09:39 PM rue_mohr: and you can weld on threads
09:41 PM Tom_L: not a very clean cut though
09:52 PM Tom_itx: that was fugly
09:52 PM Tom_itx: pc just crashed
09:53 PM Tom_itx is now known as Tom_L
09:56 PM Tom_L: early presumption about apple users: they will buy an app before getting one free
10:09 PM rue_mohr: free apps means continious ad streaming, ause thats how free app decvelopers make money
10:09 PM rue_mohr: I dont know what costs a user more in the long run, I suppose it depends on your plan
10:10 PM Tom_L: this thing is wifi only
10:10 PM Tom_L: i think
10:10 PM Tom_L: i'm not using any though, was just looking
10:12 PM rue_mohr: yea, it'll stream lots of ads with the free aps
10:12 PM rue_mohr: PLAY THIS GAME! PLAY IT NOW!
10:13 PM rue_mohr: YOU COULD WIN!
10:13 PM rue_mohr: GREAT PRIZES IN STORE!
10:13 PM rue_mohr: so, my next coding challange, I think
10:14 PM rue_mohr: anonnumberanon, did you go to sleep or are you playing?
10:14 PM rue_mohr: is to write a program that breaks the ears off polygons
10:15 PM rue_mohr: so I'll need to know if a polygon is clockwise, counterclockwise, or twisted
10:28 PM Tom_L: why do you need broke ears?
10:40 PM rue_mohr: thats how you eat a polygon
10:40 PM rue_mohr: you break off ears till there is just a triangle left
10:57 PM Tom_L: you're kinda using the openscad approach to this then
11:03 PM rue_mohr: yea, I do 2.5D
11:04 PM rue_mohr: if he dosn't want to, its a start
11:06 PM anonnumberanon: bed i have work
11:07 PM anonnumberanon: my stepper drivers will be here wednesday
11:11 PM rue_mohr: it dosn't matter, you need to know how to make someting and run it :)
