12:06 AM rue_: maybe I should get a teddy bear to keep me company in the shop
12:17 AM rue_shop3: tom, 1/8" bit, 2900 rpm, 85mm/min 0.2mm passes. how does that sit on your scales?
12:23 AM zhanx: broken
12:23 AM zhanx: feed rate at 55mm max
12:23 AM rue_shop3: ? rlly?
12:25 AM zhanx: deflection on the bit at the feed rate, you will see chatter
12:25 AM rue_shop3: hmm
12:26 AM zhanx: you are feeding faster than its diameter
12:26 AM rue_shop3: mm/min
12:26 AM rue_shop3: 3.34ipm
12:27 AM zhanx: 85 mm / min is greater than .125
12:27 AM rue_shop3: your thinking mm/sec....
12:27 AM rue_shop3: I'm sure of it
12:27 AM zhanx: wait i might be
12:27 AM rue_shop3: the cut dep is like, 0.1mm
12:28 AM zhanx: let me redo the math with the right numbers
12:28 AM rue_shop3: damn industry flipflops on feedrate units
12:28 AM rue_shop3: its annoying
12:29 AM zhanx: at 3.34ipm your in tolerance
12:30 AM zhanx: max will be 4 ish
12:30 AM rue_shop3: 101
12:31 AM zhanx: 101 will snap that bit quick
12:31 AM rue_shop3: .25mm and .3mm / pass at 90mm/min needed cooling
12:31 AM zhanx: which you don't have right yet
12:31 AM rue_shop3: I got a chip puffer
12:31 AM rue_shop3: thats it
12:32 AM rue_shop3: zhanx, did yo usee the parts finisher?
12:32 AM zhanx: you need an aquarium pump and a make shift bed to hold the coolant
12:33 AM zhanx: no i did not
12:36 AM rue_shop3: tom and I were going to build one, he was slow on the trigger
12:36 AM rue_shop3: mines done and now he says he's not really interested
12:36 AM rue_shop3: http://ruemohr.org/~ircjunk/projects/finisher/p1100379.jpg
12:37 AM rue_shop3: http://ruemohr.org/~ircjunk/projects/finisher/p1100366.jpg
12:37 AM rue_shop3: see directory
12:37 AM rue_shop3: http://ruemohr.org/~ircjunk/projects/finisher/p1100378.jpg
12:38 AM zhanx: that works
12:38 AM rue_shop3: its an interesting finish
12:38 AM rue_shop3: like an etch
12:39 AM rue_shop3: I'll post a youtube video of things going around in it
12:39 AM zhanx: ok my code sucks, stopping for the night on it
12:39 AM zhanx: getting a bit frustrated
12:40 AM rue_shop3: is it frustrated in the 1 or 0 state?
12:40 AM zhanx: 0
12:40 AM rue_shop3: whats the code?
12:41 AM zhanx: esp8266 to wifi
12:41 AM rue_shop3: ah, I used the arduino to do it
12:41 AM zhanx: it was talking now its not
12:42 AM zhanx: i am doing a pump system for the garden
12:42 AM rue_shop3: yup, ok
12:42 AM zhanx: with a flow meter on it
12:42 AM rue_shop3: you have two talking?
12:42 AM zhanx: had 5
12:42 AM zhanx: now zero
12:43 AM zhanx: need 12
12:43 AM rue_shop3: is the problem code or battery
12:43 AM zhanx: think its my code
12:43 AM rue_shop3: what did you change?
12:43 AM zhanx: relay of soil moisture to the server
12:44 AM zhanx: think my code of id is too long and its droping
12:44 AM zhanx: combined with the other measurements
12:44 AM rue_shop3: udp?
12:45 AM rue_shop3: er, iirc those dont do tcp well
12:45 AM zhanx: no should i switch to that?
12:45 AM zhanx: i thought they did tcp better
12:45 AM zhanx: let me google it
12:45 AM rue_shop3: upd is try, and if it fails nobody cares
12:45 AM rue_shop3: tcp is hammer the target till the message is delivered
12:46 AM zhanx: and it looks like UDP does checksums
12:47 AM zhanx: but has issues also
12:47 AM zhanx: think i will code a token ring call
12:48 AM zhanx: have my server call to get the stats vs them reporting and logging and then triggering
12:50 AM zhanx: if i do PID right they can check a spot getting dry and prevent it
12:52 AM zhanx: back to level zero
12:52 AM rue_shop3: plants like a little cycle you know
12:52 AM zhanx: that and the sun burns plants with wet leaves
12:53 AM zhanx: another 2 years and i might figure this out
12:54 AM rue_shop3: well, you hav the water controllable now?
12:55 AM rue_shop3: 12 zones?
12:55 AM zhanx: yes
12:55 AM rue_shop3: how about each node uses guided atonimoty?
12:56 AM zhanx: how so
12:56 AM rue_shop3: they can figure out their own things, right?
12:56 AM zhanx: not really
12:56 AM zhanx: not yet
12:56 AM rue_shop3: their esp8266?
12:56 AM rue_shop3: k
12:56 AM rue_shop3: is each node io wise the same?
12:56 AM rue_shop3: moisture, temp, light, water solinoid...
12:57 AM zhanx: the first 2 years i logged the data and based that on manual control
12:57 AM zhanx: yep
12:57 AM rue_shop3: k, dos the water supply care how many valves open at once?
12:58 AM zhanx: water supply does, only one flow meter
12:58 AM zhanx: but other than that no
12:58 AM rue_shop3: supply is ok to feed everyone at once then?
12:59 AM zhanx: no 2 at max
12:59 AM rue_shop3: ah
12:59 AM zhanx: if its all 12 zones its a very low flow rate to each zone and the zone flow is not measured yet
01:00 AM rue_shop3: so, if each zone wants to water, it could ask someone for the resource and get accept/deny
01:00 AM rue_shop3: I'm prolly working against your model :)
01:00 AM zhanx: my zones are a theory of flow rate based off buckets right now, one at a time and the flow sensor
01:00 AM zhanx: no toss ideas at me pleace
01:01 AM zhanx: please
01:01 AM zhanx: i don't want to add more money to the setup just code it right
01:01 AM rue_shop3: so, two objectives are to maintain ideal moisture conditions and collect data about each area, for performance eval
01:01 AM zhanx: yep
01:02 AM rue_shop3: what can each node do now?
01:02 AM rue_shop3: they were reporting data
01:02 AM zhanx: with each zone moisture being set on its own
01:02 AM zhanx: still just that, i want to turn the data in to real world use now
01:03 AM zhanx: i know i use x gallons per zone now,
01:03 AM zhanx: each zone needs y water, but the zone reporting is failing me
01:03 AM rue_shop3: is the data you have applied_water and measured_moisture ?
01:03 AM zhanx: yes
01:04 AM zhanx: and time, temp and sun light while watering
01:04 AM rue_shop3: k
01:04 AM zhanx: soil temp*
01:04 AM rue_shop3: from that, can you code a moisture_maintain() that has a K factor you can adjust?
01:05 AM zhanx: i only have one outside temp monitor
01:05 AM zhanx: issue with that is plants need to go dry and get moisture like you said
01:05 AM zhanx: i am stuck in 2 places on that
01:05 AM rue_shop3: I'm thinking, everyone works on maintaining their zone, but each zone has a different K factor, aside, there is an interlock on water requests
01:06 AM rue_shop3: dry_level_thres dry_period_timer
01:06 AM zhanx: true and add in sun light
01:07 AM rue_shop3: well, all part of moisture_maintain()
01:07 AM zhanx: after this is solved i want to add in weeding. that will be 1000x harder
01:07 AM rue_shop3: things like a temp lockout for winter
01:07 AM zhanx: winter i have to pull the system up here
01:08 AM rue_shop3: you cant just drain it?
01:08 AM zhanx: nope
01:08 AM rue_shop3: 170psi or air
01:08 AM rue_shop3: everyone open
01:08 AM zhanx: i am at water level
01:08 AM rue_shop3: have the kids run around and catch the sprinkler heads from the sky
01:08 AM rue_shop3: oh
01:09 AM zhanx: its a catch 22
01:09 AM rue_shop3: your one of the first places to go when the sea rises
01:09 AM zhanx: in the summer i am below it, the spring and fall under it,
01:09 AM rue_shop3: it'll be sooner now that trump said it dosn't matter
01:09 AM zhanx: no i am at 4200 feet gsl
01:09 AM rue_shop3: ah
01:09 AM rue_shop3: so you should be growing rice
01:10 AM zhanx: you have mad groper as PM so lots of room to talk
01:11 AM zhanx: and yes the state of america is right now if you did something 10+ years ago you should be fired for it
01:12 AM rue_shop3: well, I'v more than exhausted the thoughts I'v had about a system for myself
01:13 AM rue_shop3: blooming greenhouse is still empty
01:13 AM zhanx: what?
01:13 AM zhanx: bad rue
01:13 AM rue_shop3: what should be in it!?
01:14 AM zhanx: tomatoes, cucumbers and peppers for the heat
01:14 AM rue_shop3: I have to thin out the maple tree over it tho
01:14 AM rue_shop3: oh
01:14 AM rue_shop3: there is a tomato in there, its not that happy
01:14 AM zhanx: you can do onions on the floor with garlic
01:14 AM zhanx: couple of cabbage in the back
01:14 AM rue_shop3: onions are alive
01:14 AM rue_shop3: hmm
01:15 AM zhanx: trying eggplant again this year
01:17 AM rue_shop3: wtf I supposed to do with a blooming e... oh you...
01:18 AM zhanx: eggplant lasagna
01:20 AM rue_shop3: ok
01:20 AM rue_shop3: see, I know what the issue is right there, I dont cook
01:20 AM rue_shop3: I want to be a bot, and not have to worry about my cooking-deficiency
05:39 AM Tom_L: 4k rpm .001" chipload 8 ipm
05:40 AM Tom_L: 6 ipm for deep full cuts
05:43 AM Tom_L: calculate what your machine can do from that but 4k rpm isn't too much
05:44 AM Tom_L: it's the rpm / chipload ratio that matters
12:40 PM rue_: as you get up to the limit you need colling to , cause its aluminum and starts to gum up
03:52 PM rue_shop3: furrywolf, I suppose, if your using equally spaced sensors, a single track encoder can just be worked out by rotating the disc and apply the next grey count value
07:56 PM rue_: Tom_L, I found a motor for the cnc machine
07:56 PM rue_: its awesome, but
07:56 PM rue_: might be too big
08:03 PM Tom_L: never too big
08:03 PM Tom_L: cut more blocks to size, need to finish one more another day
08:03 PM Tom_L: takes quite a while
08:13 PM rue_shop3: oh I'll show you a pic
08:13 PM rue_shop3: first, I'm stripping down a stereo
09:25 PM rue_shop3: arg
09:25 PM rue_shop3: I grabbed a stereo from the scrap metal pile to get the tuning diodes, I stripped it down but I want to keep everything
09:49 PM rue_shop3: this motor might be better for my drillpress
09:55 PM rue_shop3: curtis 1203A
09:56 PM rue_shop3: 24V 90A
10:04 PM rue_shop3: oh, its etched on the trace side
10:04 PM rue_shop3: thats stupid-easy
10:31 PM Tom_L: no pics?
10:53 PM rue_: oh gotta catch up
10:53 PM rue_: hmm
10:58 PM Tom_L: damn, i like this new micrometer...
11:02 PM rue_: https://youtu.be/TG5aC44US94
11:05 PM Tom_L: just add water
11:05 PM rue_: there is a hole in the bottom, I was pouring in a bit now and again
11:06 PM Tom_L: recycle it
11:06 PM rue_: dont ahve a pump that can take grit
11:06 PM Tom_L: filter it
11:09 PM Tom_L: https://www.youtube.com/watch?v=mkQ2pXkYjRM
11:20 PM rue_: MMMMMOOOOOOOOOOON
11:20 PM __M00N__: yeah!
11:20 PM __M00N__: you know it
11:20 PM rue_: so, cnc tommorow?
11:20 PM __M00N__: yes
11:20 PM __M00N__: in the morn
11:20 PM rue_: see you 11:00 sharp then!
11:20 PM __M00N__: ha!
11:20 PM __M00N__: 8-9 more like it
11:21 PM rue_: I'll be asleep
11:21 PM __M00N__: what shal we start with general size design and weldinng?
11:21 PM rue_: well
11:21 PM rue_: have you seen toms?
11:21 PM __M00N__: nope
11:22 PM Tom_L: oh rue_ i had a bright idea today
11:22 PM Tom_L: i had to cut the length of 11.4" 7/8 thick material
11:22 PM Tom_L: so i remembered i had a slitting saw
11:22 PM Tom_L: .040" thick
11:23 PM Tom_L: thought it would work great but the spindle motor just didn't have the poop to drive it
11:23 PM rue_: I cant find the image
11:23 PM Tom_L: so i wound up cutting it with the 1/8" em
11:23 PM Tom_L: to find out i cut the wrong piece
11:23 PM __M00N__: :P
11:24 PM Tom_L: so 7/8 / .060 per cut do the math
11:24 PM rue_: there is another deisgn too
11:24 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/
11:24 PM Tom_L: it's all there
11:24 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Column_Mill_VMC.jpg
11:24 PM __M00N__: k looking
11:24 PM Tom_L: idea
11:25 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/spindle_cooler/Mill1.jpg
11:25 PM Tom_L: end result
11:25 PM rue_: Tom_L, do you remmeber the make of that other cnc thts not sherline
11:25 PM Tom_L: taig?
11:26 PM Tom_L: there's a couple i think
11:26 PM rue_: http://www.positiveflow.com/taig/cncmill7b.JPG
11:28 PM rue_: __M00N__, I cant find the good images, but the taig design is a easy one
11:28 PM Tom_L: https://www.youtube.com/watch?v=VUDHCXu4Pwo&t=2s
11:29 PM Tom_L: i have no soumd but am told that's noisy
11:29 PM rue_: http://www.cartertools.com/cncml01.jpg
11:29 PM rue_: sliders are a problem
11:31 PM Tom_L: i'm glad i added fuses where i did
11:31 PM Tom_L: popped a few spindle motor fuses
11:32 PM Tom_L: i should put a breaker on it
11:33 PM rue_shop3: wow, ok, youtube really distracted me there
11:33 PM __M00N__: very cool machine
11:33 PM rue_shop3: Tom_L, so, should I go with a 90V 24V motor?
11:34 PM Tom_L: a what?
11:34 PM Tom_L: i'm of the opinion you can't have too big a spindle motor
11:34 PM __M00N__: i like that standpoint
11:35 PM Tom_L: and i'm convinced now i would be hard pressed to stall my Z axis
11:35 PM Tom_L: it's 3:1 and X&Y are direct
11:35 PM Tom_L: X will push the mill across the table instead of stalling
11:35 PM Tom_L: i bumped into something once :D
11:36 PM Tom_L: never lost a step
11:36 PM __M00N__: wow
11:36 PM Tom_L: i got the biggest nema23 i could find
11:36 PM rue_: I'm gonna say I got the last of anything usefull from the scrap metal pile
11:37 PM rue_: oh Tom_L show him your machine
11:37 PM rue_: see what overview pic YOU can find
11:38 PM rue_: __M00N__, I got the pcb plotter working again
11:38 PM Tom_L: i did
11:38 PM rue_: we can now make curcit bnoards
11:38 PM rue_: http://ruemohr.org/~ircjunk/images/p1100384.jpg
11:39 PM rue_: ^ Tom_L motor for the new cnc?
11:39 PM Tom_L: if Z can lift it sure
11:39 PM rue_: I'm pretty sure that needs no scale reference
11:39 PM rue_: hahah
11:39 PM Tom_L: somebody tried to get me to get one about that size
11:39 PM rue_: you just do a long belt and let it take up the z difference
11:39 PM __M00N__: i cant you tube yet im on a RDP session
11:39 PM rue_: I hav to see if it works
11:40 PM rue_: the controller is in good shape
11:40 PM __M00N__: wow
11:40 PM __M00N__: you got that today?
11:40 PM Tom_L: http://dealerselectric.com/Y522.asp
11:41 PM Tom_L: somebody thought i should use that one
11:41 PM Tom_L: along with a vfd
11:42 PM __M00N__: yeah cuz 3 phaze
11:42 PM Tom_L: i was looking at a servo
11:43 PM Tom_L: i think vfd would be easier for linuxcnc to drive
11:43 PM Tom_L: although it will do modbus or analog
11:44 PM __M00N__: modbus?
11:44 PM Tom_L: sortof a serial protocol i think
11:44 PM __M00N__: ok
11:44 PM Tom_L: industrial
11:44 PM __M00N__: do you buy adapters for that sort of thing?
11:44 PM Tom_L: i've never tried it but know some that have
11:45 PM Tom_L: you can
11:45 PM Tom_L: i may have what i need here for it
11:45 PM Tom_L: i haven't looked in to modbus that much
11:46 PM Tom_L: http://linuxcnc.org/docs/2.7/html/man/man1/hy_gt_vfd.1.html
11:46 PM __M00N__: I like ttl thus far
11:46 PM Tom_L: it will drive a Huanyang vfd though
11:46 PM Tom_L: RS485
11:46 PM Tom_L: (modbus)
11:46 PM Tom_L: i've got RS422? i think
11:47 PM Tom_L: but mesa makes an adapter
11:47 PM __M00N__: never heard of rs485
11:47 PM Tom_L: electrical characteristics are a bit different
11:47 PM Tom_L: but it's just serial
11:47 PM rue_shop3: 422 and 485 are differential pairs
11:48 PM rue_shop3: 422 uses 2pr and 485 uses 1 pair
11:48 PM Tom_L: my 7i47 is differential
11:48 PM Tom_L: but i'm using alot of it single ended
11:48 PM rue_shop3: Tom_L, , I ahve an elevator door motor thats 240vdc
11:48 PM rue_shop3: iirc less than 1hp
11:49 PM rue_shop3: 1/6hp
11:49 PM rue_shop3: 1140rpm
11:49 PM __M00N__: like canbus i see
11:49 PM Tom_L: small
11:49 PM rue_shop3: its big tho
11:49 PM Tom_L: sorta
11:49 PM Tom_L: canbus is more automotive
11:49 PM rue_shop3: 1.5x the size of the sherline
11:50 PM Tom_L: i'd rather go 2x and have a shitload of low end torque
11:50 PM Tom_L: gotta get some sleep
11:51 PM __M00N__: night
11:51 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Belt_Guard/Belt_Guard2.jpg
11:51 PM Tom_L: rather proud of that
11:51 PM rue_shop3: so, I still need a power supply for the shop amp
11:51 PM Tom_L: mig welded
11:51 PM rue_shop3: :)
11:52 PM rue_shop3: I realized I have shielding gas now
11:52 PM rue_shop3: I should try the mig out before that tank is empty
11:52 PM rue_shop3: arg, next on the todo list is 'bot rings' and I cant do the cutting now
11:52 PM rue_shop3: house solar, and its dark...
11:52 PM rue_shop3: shop speakers
11:52 PM rue_shop3: ok, I need a 12V...
11:53 PM rue_shop3: 10A power supply
11:53 PM rue_shop3: oh.. wait...
11:53 PM __M00N__: got it
11:53 PM * rue_shop3 looks at 3d printer beside him
11:53 PM rue_shop3: hmm
11:53 PM Tom_L: i got a 12v 45A supply
11:53 PM rue_shop3: wait there was another one
11:53 PM __M00N__: geeze
11:54 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/12v_supply3.jpg
11:54 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/12v_supply2.jpg
11:54 PM rue_shop3: looks like 12A
11:54 PM rue_shop3: for led signs maybe, their crazy
11:54 PM Tom_L: rv charger
11:55 PM rue_shop3: ah
11:57 PM furrywolf: heh, I had that exact supply. I still do have it, although it's now evidence, not a usable supply...
11:58 PM furrywolf: it didn't like 208V.
11:58 PM furrywolf: and I still haven't gotten reimbursed for the new one I had to buy to replace it.
11:59 PM furrywolf: it very, very much did not like 208V. pretty much every part of it fried, and the main filter caps popped...
11:59 PM Tom_L: later..
11:59 PM rue_shop3: good one
11:59 PM rue_shop3: how did you mix up 208 into it?
11:59 PM furrywolf: I did not.
11:59 PM rue_shop3: ah
