12:00 AM XXCoder: nice
12:03 AM XXCoder: definitely more fancy than aliexpress one lol
12:03 AM XXCoder: probably has HUGE backlash on those cheapies
12:03 AM `Wolf: https://i.imgur.com/OYrul3t.jpg https://i.imgur.com/ZCsPPNP.jpg
12:03 AM `Wolf: this is all ball screws
12:04 AM `Wolf: I actually bought the base kit for my X1, when it arrived I was looking at it before installing it and said screw it and got the LMS high torque column and head/spindle
02:17 AM Deejay: moin
02:22 AM gloops: if ever i make another router it will be the last
02:22 AM XXCoder: why?
02:22 AM gloops: a lot of work
02:23 AM gloops: if i started again i would wait and go the whole hog, full size, full power, everything, one build
02:23 AM gloops: no more upgrading, no more improvements possible
02:31 AM archivist: famous last words
02:32 AM gloops: you cant build many of these in a year
02:33 AM `Wolf: just retrofit a real VMC =P
02:34 AM gloops: you dont see many old routers though
02:35 AM gloops: to refit, they dont exist as an analogue machine
02:36 AM `Wolf: thats because no big manufacturers make a commercial cnc router that I know of, part of the reason you don’t see old ones for sale
02:37 AM `Wolf: “old” VMC on the other hand with controller issues you can find for cheap every once in a while
02:37 AM gloops: http://www.ebay.co.uk/itm/BIESSE-ROVER-J-FT-1224-8-x-4-ft-CNC-ROUTER-39-000-VAT/263072822749?
02:37 AM gloops: you can get one for 7k, i reckon you could build it for 2
02:38 AM CaptHindsight: from wooden sticks and found stones
02:38 AM `Wolf: ^
02:39 AM gloops: few servos, linear bearings, spindle etc
02:39 AM CaptHindsight: https://www.automationtechnologiesinc.com/Unassigned/cnc-router/kl-1325-cnc-machine/ just under $10k
02:40 AM CaptHindsight: you really don't want to see it up close
02:40 AM `Wolf: let me know if you find quality linear bearings 8’ in length for cheap
02:40 AM * `Wolf won’t hold his breath
02:40 AM XXCoder: I used to run haas cnc router, huge one
02:40 AM XXCoder: $100k
02:40 AM XXCoder: and oit was shit
02:41 AM XXCoder: it had to be fixed severial times before they found out spindle was 1 hp and not 4 hp as stated at website
02:41 AM CaptHindsight: 4hp intermittent
02:41 AM `Wolf: I know some of the big names make them, never seen any for sale used tho
02:41 AM CaptHindsight: 5% duty cycle :)
02:41 AM gloops: yeah you would probably be pretty shocked with the crappiness of that when you opened the box
02:41 AM `Wolf: not that I have been looking lol
02:42 AM enleth: Wolf__: there are commercial routers, made for the furniture industry
02:42 AM enleth: someone here was retrofitting one too
02:42 AM enleth: the thing had a bazillion of spindles instead of a toolchanger and had a weird aspect ratio, very long and narrow
02:42 AM `Wolf: yeah, not common like I said =)
02:42 AM gloops: the old ones become obsolete when the built in controllers are knackered or just too slow to compete
02:42 AM enleth: but it was most definitely a factory-made CNC router
02:43 AM enleth: it's just a completely separate market from the metal cutting CNC machines, separate vendors, separate controls, etc.
02:44 AM CaptHindsight: separate definition of quality
02:44 AM gloops: routers are usually made from standard industry components, they dont make router castings and so on
02:44 AM gloops: kids bolt extrusions together that are use in automated packing industry
02:44 AM CaptHindsight: t-slot, 2x4's, cinder block, what else do yah needs?
02:45 AM enleth: CaptHindsight: probably enough to cut minced tree carcasses
02:45 AM `Wolf: packing machines are a unique case imo
02:45 AM CaptHindsight: don't forget fermented dairy products
02:46 AM gloops: cnc cutting machines are a tiny share of the linear motion industry
02:46 AM CaptHindsight: cnc putting machines
02:46 AM gloops: you buy ''cnc' linear rails, they were made for shrink wrapping machines
02:47 AM CaptHindsight: I hereby decree from this day forward that 3d printers will now be called "putting machines"
02:48 AM XXCoder: yay I will get cnc putting machine evenually
02:49 AM CaptHindsight: XXCoder: you might get some offers in here
02:49 AM gloops: if you set out to build a cnc, do not begin with a faint heart
02:49 AM CaptHindsight: http://www.3ders.org/pricecompare/3dprinters/
02:49 AM gloops: take your inspiration from the massive engineering feats of the great builders
02:50 AM gloops: isambard kingdom brunel the SS GREAT eastern
02:50 AM CaptHindsight: so definitely not from my last link :)
02:50 AM gloops: or the german Jaegdpanther tanks
02:51 AM CaptHindsight: gloops: they weren't so bad
02:51 AM CaptHindsight: just had trouble getting materials to make them, and people, fuel, etc etc
02:51 AM gloops: think big, think powerful, think grand
02:52 AM CaptHindsight: so think more Manhattan project than Titanic?
02:52 AM CaptHindsight: or eh...
02:53 AM CaptHindsight: Spruce Goose
02:53 AM XXCoder: spruce goose is best heh
02:53 AM gloops: the titanic was ok, i reckon that was an insurance job
02:53 AM XXCoder: ya know, I saw it few times
02:54 AM CaptHindsight: I heard that the icebergs were actually from Saudi Arabia
02:55 AM XXCoder: it is. they mine ice and sometimes they acciently dump ice into ocean on way back
02:55 AM CaptHindsight: XXCoder: is the Goose really big?
02:55 AM XXCoder: pretty big allright
02:55 AM CaptHindsight: go inside?
02:55 AM XXCoder: sorta. pilot area was closed (times schecuded tours there)
02:56 AM XXCoder: but I could see rest of it
02:56 AM XXCoder: its pretty caverous
02:56 AM XXCoder: tons wood framing etc
02:57 AM XXCoder: it was definitely interesting. oh they dont actually allow us to explore, cargo area was screened with plastic
02:57 AM CaptHindsight: https://en.wikipedia.org/wiki/Hughes_H-4_Hercules interesting comparisons to some modern giants
02:57 AM XXCoder: there was no floor and such, it was prototype after all
02:58 AM XXCoder: the nose was supposed to flip up, but since first failed so bad they never built second one to test flip up nose one
02:58 AM CaptHindsight: https://upload.wikimedia.org/wikipedia/commons/thumb/d/d8/Hughes_H-4_Hercules_Interior_Full_Flight_Deck_EASM_4Feb2010_%2814587781251%29.jpg/1024px-Hughes_H-4_Hercules_Interior_Full_Flight_Deck_EASM_4Feb2010_%2814587781251%29.jpg
02:59 AM XXCoder: CaptHindsight: ya spurce goose was kinda like that inside also. ribbing framing but nothing besides that
03:00 AM XXCoder: yet it failed to really fly. funny, that
03:00 AM XXCoder: they didnt even paint inside lol
03:01 AM XXCoder: apparently the pilot area habe more than I expected. https://otrwjam.files.wordpress.com/2011/05/img_3606.jpg
03:02 AM XXCoder: basically what I saw https://upload.wikimedia.org/wikipedia/commons/5/5a/Spruce_Goose_interior_4.jpg
03:02 AM CaptHindsight: gloops: so https://www.interlakesbases.com/images/gallery/large-machine-base.jpg
03:02 AM CaptHindsight: vs ...
03:03 AM CaptHindsight: http://www.kathyquilts.com/images/D/Grace_Company_SR2_Quilting_frame_600.jpg
03:03 AM XXCoder: cnc sewing
03:04 AM gloops: the recoil will pull that to pieces!
03:04 AM CaptHindsight: https://www.interlakesbases.com/images/gallery/machine-table.jpg
03:04 AM CaptHindsight: http://tsiextrusions.com/wp-content/uploads/2015/10/DSC007693.jpg
03:05 AM XXCoder: thats pretty heavy duty for cheapo machine
03:05 AM CaptHindsight: reminds me of https://i.pinimg.com/736x/d6/56/76/d656761b69cd39ef708fa956bf0ab772--the-three-stooges-upstairs-bathrooms.jpg
03:06 AM XXCoder: wow now thats quality pumbling heh
03:07 AM CaptHindsight: how was everyones xmas eve eve?
03:08 AM XXCoder: boring.
03:08 AM CaptHindsight: consumed mass quantities here
03:12 AM CaptHindsight: the last few years around here very little is open after 4pm tomorrow until the 26th
03:12 AM CaptHindsight: even gas stations
03:14 AM CaptHindsight: gloops: you might enjoy http://www.mech.utah.edu/~me7960/lectures/Topic14-DesignOfMachineStructures.pdf
03:16 AM gloops: well through experience ive obtained the answers to all those questions
03:16 AM gloops: how stiff should it be? it should be stiff, its either stiff or it isnt stiff, if it isnt stiff you arent there yet
03:17 AM CaptHindsight: ^^ turns vibration into heat
03:17 AM CaptHindsight: hasta!
03:17 AM gloops: it cannot vibrate a planet
03:19 AM archivist: but the planet is constantly moving and buggering up your accuracy
03:27 AM `Wolf: little things… https://i.imgur.com/5hRN4bP.jpg
03:28 AM archivist: but it is stationary
03:30 AM `Wolf: https://i.imgur.com/kVyqNde.jpg better?
03:32 AM * archivist guesses the duff display digit
03:36 AM `Wolf: cam caught the led refresh, 760, none of the speed settings match the tach lol
03:36 AM archivist: I was pulling your leg :)
03:37 AM archivist: does it turn nicely with no chatter
03:39 AM Contract_Pilot-A: evening
03:40 AM `Wolf: yeah, it turns pretty good long as I put good cutter in it
03:40 AM `Wolf: I do need to replace the motor, for some odd reason it has a 1/3hp on it lol
03:41 AM archivist: enough for light work
03:42 AM `Wolf: yup, it wasn’t happy with the idea of power tapping 3/8-16 in to alum lol
03:43 AM `Wolf: didnt help that it also only had 3” pulley on the motor not the 3”/2”
03:46 AM `Wolf: now I need to make a die holder so I can cheat some threads on to some rod stock lol
03:47 AM archivist: but it has a screw cutting gearbox, do it properly :)
03:47 AM `Wolf: lead screw isn’t here yet
03:47 AM archivist: I sometimes screw cut and clean up with a die
03:49 AM `Wolf: still missing change gears and thread dial
03:49 AM `Wolf: going to 3d print both lol
03:50 AM XXCoder: interesting https://www.youtube.com/watch?v=mX6P9CwSm7I
03:56 AM gloops: this looks really well made https://www.ebay.co.uk/itm/Trend-Router-Bit-1-4-shank-Ovolo-panel-cutter-Dia-25-x-depth-12-7-mm-cut-New/253288907025?
03:57 AM gloops: the real trend cutter is like 60 quid
04:08 AM `Wolf: meh wood chuck bit
04:44 AM jthornton: morning
04:50 AM Deejay: hey
04:54 AM jthornton: gloops: so far each egg has only weighed 36 grams lol
05:06 AM gloops: you might get some funny shaped ones to start as well jthornton
05:07 AM jthornton: so far they all look normal just small... odd thing it's not the biggest bird laying the eggs but a smaller one
05:10 AM gloops: are yours rhode islands jthornton?
05:10 AM jthornton: yes all rhode island reds
05:11 AM gloops: small, funny shaped, doube yolks and stuff like that is pretty normal at the start - RIR if nothing disturbs them and fed well should have a run of about 300 eggs once they start
05:12 AM jthornton: nice
05:14 AM gloops: ours lay in fits and starts, theyre pretty feral heh, some older birds a few younger ones
05:16 AM XXCoder: weird tool https://www.youtube.com/watch?v=LZAdYVhInXA
05:16 AM XXCoder: chainsaw angle grinder
05:17 AM jthornton: http://gnipsel.com/images/chickens/nestbox/RONB-17.jpg
05:17 AM jthornton: http://gnipsel.com/images/chickens/nestbox/RONB-18.jpg
05:17 AM jthornton: http://gnipsel.com/images/chickens/nestbox/RONB-19.jpg
05:17 AM jthornton: http://gnipsel.com/images/chickens/nestbox/RONB-20.jpg
05:18 AM jthornton: that's the roll out nest box I built for them
05:19 AM gloops: nice job with the box
05:19 AM jthornton: my neighbor has one of those wood hogs for his angle grinder
05:19 AM jthornton: thanks
05:19 AM jthornton: hind sight being 20-20 I would have made it 2" taller and 6" deeper
05:20 AM XXCoder: nice
05:20 AM gloops: dangerous tool though
05:20 AM XXCoder: yeah he outlined the dangers
05:20 AM XXCoder: jthornton: soon you be rolling in lots eggs
05:21 AM XXCoder: breakfast everyday or what?
05:21 AM jthornton: breakfast, lunch, dinner, snack lol
05:21 AM XXCoder: and egg throwing ;)
05:21 AM jthornton: no wasting eggs lol, they cost too much
05:22 AM gloops: i made a bank of 5 boxes, well have made 2 similar, each box seperated by a partition, they always only lay in 1 box
05:22 AM XXCoder: if you like egg mcmuffin, you could use a small dish microwave-safe, get egg in it, add tiny amount of water and microwave
05:23 AM XXCoder: I could make pretty accurate mcmuffin with sausage and egg. for way less than old golden arches charge for em
05:23 AM jthornton: that's the reason I just made one big box, I hope big enough for at least 2 at a time
05:23 AM gloops: 4.5 inch grinder should be handle-able, i would like to do it with a bigger grinder or wheel
05:23 AM jthornton: I need to hook up my BMP280 to the RPi
05:24 AM gloops: i mean i wouldnt like to do it with 9 inch
05:25 AM jthornton: that blade cuts very well with no tendency for kickback, I've used my friends before
05:26 AM gloops: well back to the garage for me
05:33 AM XXCoder: I don't know why I love that channel https://www.youtube.com/watch?v=t32Kf9iohsk
05:34 AM XXCoder: I never owned any toy cars
05:34 AM XXCoder: Im not really restorer of any kind
05:34 AM XXCoder: but I love his videos lol
06:00 AM nallar is now known as Ross
06:23 AM * jthornton can't remember how he did the remote desktop into the rpi
06:24 AM archivist: vnc
06:29 AM Contract_Pilot-A: Gonna be a long night
06:29 AM Contract_Pilot-A: it has been a long night
06:29 AM XXCoder: oh yeah
06:29 AM XXCoder: I checked into orangepi see if it could run linuxcnc
06:29 AM Contract_Pilot-A: My belly is yellow gonna be a good bruise
06:29 AM XXCoder: answer is yes, techinically
06:29 AM XXCoder: but no RT kernel
06:30 AM Contract_Pilot-A: I was thinking of the NUC
06:30 AM XXCoder: too bad because if it has decent latency it would rock as its pretty tiny full computer.
06:30 AM XXCoder: other one is BBB (beaguebone something?)
06:31 AM Contract_Pilot-A: the beaglebone they use that on the Centroid
06:31 AM Contract_Pilot-A: was Chatting on FB with someone about it yesterday
06:32 AM Contract_Pilot-A: I think he has his hear set on the acorn i think he will come to found out it is very limited
06:34 AM XXCoder: running linuxcnc on bbb?
07:00 AM jym: XXCoder: I've heard of that, then using a tablet for the controls
07:00 AM jym: Anyone interested in a Model M ?
07:57 AM Tom_L: 22F
07:58 AM jym: Tom_L: I feel for ya
07:59 AM jym: Tom_L: Or I guess i would feel for ya, but too cold and numb to
08:00 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Z_Axis_Assembly_Up.jpg
08:00 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Assembly/Z_Axis_Assembly_Down.jpg
08:00 AM Tom_L: got Z somewhat assembled last night
08:01 AM jym: Holy Crap! WTH you gonna mill with that beast, cobolt?
08:02 AM Tom_L: if need be
08:02 AM jym: haha, ok, fair enough =)
08:03 AM trentster: Hi all, I have read docs and watched videos of people calibrating an axis via the .ini file SCALE setting. This works fine when the default unit is INCH and you can adjust scale up or down by full digits. But what does one do when they have MM as the default scale and the deviation is now under a full step. e.g, I am getting 0.002mm over overtravel per 1 MM and there fore I need to adjust my scale(currently 80) down by 0.24 - Do
08:03 AM trentster: scale setting support decimal places? e9 80-0.24 = 79.76 ?
08:03 AM jym: If that's Z, wheres X & Y going to go?
08:03 AM Tom_L: you're looking at Y
08:03 AM Tom_L: and X will mount on top
08:03 AM _methods: lookin good
08:04 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Column_Mill_VMC.jpg
08:04 AM Tom_L: there is a plan.
08:05 AM jym: Tom_L: What happens when X is at either end?
08:05 AM _methods: you going to leave all the tubing hollow?
08:05 AM _methods: or are you going to fill it all with cement or something
08:05 AM Tom_L: i'm not sure yet, it will probably ring too much if i don't
08:05 AM Tom_L: jym, i'm gonna add some leg supports out the sides
08:05 AM jym: Tom_L: Expanding Foam In A Can
08:05 AM _methods: i guess try hollow and see how it works out
08:05 AM Tom_L: first cuts will be
08:06 AM Tom_L: i can always use the column as a trash can
08:06 AM archivist: trentster, yes
08:07 AM jym: Tom_L: That must have been fun cutting a curve into the tubing like that
08:08 AM Tom_L: curve?
08:08 AM Tom_L: oh the cutout?
08:08 AM Tom_L: wasn't bad
08:08 AM trentster: archivist: thanks, I kinda thought it correlated to full steps(or microsteps).
08:08 AM jym: Tom_L: notch, where the Y leadscrew motor would go
08:09 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/StepperMount2.jpg
08:09 AM jym: Tom_L: Oh, ok, that doesn't as bad =)
08:10 AM jym: fairly clean actually =)
08:10 AM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Mill_Steel/Steel11_mounts.jpg
08:10 AM Tom_L: there was a plan.
08:11 AM JT-Shop: I have a maple hmi machine code file that has a password protection... password is unknown and original programmer long gone. Any ideas how to crack the file and find the password
08:12 AM archivist: do you have a spec for the file format
08:13 AM Tom_L: http://www.dcitech.com/slides/slide/ezwareplus-programming-manual-168/pdf_content
08:13 AM Tom_L: that's not the programming manual is it?
08:15 AM Tom_L: The default password is 111111
08:15 AM archivist: I just found http://www.maplesystems.com/cgi-bin/download/manuals4.asp but "a file" could fit anything
08:16 AM JT-Shop: I don't even know what file format it is, I've looked at it with a hex editor but not found anything useful
08:16 AM archivist: many software locks end up with a yes no that needs flipping
08:17 AM JT-Shop: it is a HMI5000 hmi
08:17 AM JT-Shop: the password is numerals only, I've figured that much out
08:17 AM Tom_L: ^^ 111111 was the default apparently
08:18 AM Tom_L: at least for access to the hardware
08:19 AM Tom_L: http://www.maplesystems.com/technote_pn.htm
08:23 AM JT-Shop: yea 111111 is the upload/download password
08:24 AM Tom_L: https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwjqxbq37KLYAhUTS2MKHWWcA5oQFggnMAA&url=http%3A%2F%2Fwww.maplesystems.com%2Fcgi-bin%2Fdownload%2Fxfrfile-technote.asp%3Ff%3D09075035.pdf&usg=AOvVaw3qF71koA8oxuoll5h-1crU
08:24 AM Tom_L: for converting a file
08:24 AM Tom_L: might help
08:26 AM Tom_L: https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=5&cad=rja&uact=8&ved=0ahUKEwjqxbq37KLYAhUTS2MKHWWcA5oQFgg_MAQ&url=http%3A%2F%2Fwww.maplesystems.com%2Fcgi-bin%2Fdownload%2Fxfrfile-technote.asp%3Ff%3D09075034.pdf&usg=AOvVaw2kv5CHT9mouAswGYK726g-
08:27 AM Tom_L: file setup and retreval
08:28 AM Tom_L: This technical note describes how to log data from PLC registers to a USB memory stick and then convert the data file on the USB memory stick into a .csv file format that can be read by Excel or other text editors programs
08:30 AM jthornton: I can't open the file until I decode it with the decoder
08:32 AM jthornton: http://gnipsel.com/files/misc/FOOT-FORWARD.zip
08:32 AM jthornton: that's the file if anyone wants to take a crack at it
08:35 AM archivist: crack the decoder
08:44 AM Contract_Pilot-A: When you buy somthing on e-bay untested and sold for parts only and await its arrival if it powers up good if not makes for blog content win win
08:45 AM Contract_Pilot-A: Just have to find the pinout for the 5 mini din to give it 3.3v and 5V to see!!!
08:45 AM Contract_Pilot-A: If it works will be a cool tool.
08:46 AM Contract_Pilot-A: I will find out tuesday i hope.
08:55 AM Tom_itx: JT-Shop, have you seen this page: http://shorelinetek.com/
08:55 AM Tom_itx: easybuilder
08:55 AM Tom_itx: may not be the same hmi format
08:59 AM JT-Shop: yea each manufacturer is different I'd bet, but the similar name is strange... the hmi software I use is easybuilder5000 which only works for the 5000 series hmi's
08:59 AM Tom_L: kinda like jtag, they're supposed to be compatible but none are
09:01 AM Tom_L: nothing in the manual about password protection?
09:03 AM Tom_L: hah, found your post on pictalk :)
09:07 AM Tom_L: you don't have the .mtp file do you?
09:07 AM Tom_L: that's the uncompiled file format for xob
09:08 AM Tom_itx: https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=4&cad=rja&uact=8&ved=0ahUKEwjTva2e9aLYAhXGyoMKHS9eCxkQFghAMAM&url=https%3A%2F%2Fwww.watlow.com%2F-%2Fmedia%2Fdocuments%2Fuser-manuals%2Fssoime-c.ashx&usg=AOvVaw3ZmMUcRFsfZP-t3HnxaZoP
09:08 AM Tom_itx: P. 185
09:08 AM Tom_itx: ish
09:10 AM Tom_itx: Once a project is comiles with Decompilation is prohibited option checked, it cannot be decompiled. There is no "backdoor" password to override it.
09:12 AM Tom_L: might be easier to hunt down the programmer than to start over.
09:14 AM JT-Shop: Tom_itx: the .mtp file is what you get after decompliling
09:14 AM JT-Shop: programmer long gone
09:14 AM Tom_L: doesn't look good for you
09:17 AM Tom_L: never say never... i ran into the guy that used to fix my bud's machines 25 yrs ago teaching at the Vo-tech a while back
09:17 AM Tom_L: unless of course he's deceased
09:20 AM Contract_Pilot-A: Gonna try 1/2 dose pain meds today see if i can get this VFD wiring sorted out.
09:38 AM archivist: Contract_Pilot, supposed to rest not wire while high :)
09:50 AM Contract_Pilot-A: Yea, I know1
09:55 AM Contract_Pilot-A: Looks liek tormach on theor lathe is only using 2 home switches.
10:00 AM gloops: theres got to be a few quid in this back yard metal casting
10:01 AM Deejay__ is now known as Deejay
10:12 AM sync: Contract_Pilot-A: why not?
10:17 AM jdh: why would they use more than 2?
10:17 AM Contract_Pilot-A: Lot less wiring to only have home switches onlu
10:18 AM Contract_Pilot-A: Figured they would have 4
10:21 AM Contract_Pilot-A: Hope this NPN prox sensor works out
10:23 AM Contract_Pilot-A: Tormach Board is Sinking inputs
10:25 AM jdh: you can have only one home per axis
10:26 AM Contract_Pilot-A: 1 home and 1 limit
10:27 AM Contract_Pilot-A: looks like they are only using 1 home and soft limits not mechanical
10:32 AM Contract_Pilot-A: Cracked the WJ200 book opned i closed it hahahaha even 1/2 dose i cannot follow hell even sober its a PITA
10:43 AM * gloops realises he should be swatting up on homing and not watching playing in the back yard vids
10:50 AM phipli: afternoon
11:02 AM JT-Shop: hey
12:30 PM phipli: how goes?
12:34 PM jthornton: got 4 eggs so far 36g, 30g, 36g and 36g she has not laid one yet today
12:38 PM skunkworks: your weighing the eggs?
12:45 PM gloops: the weight of each egg is texted to the cell phone after the robot arm collects them lol
12:45 PM phipli: jthornton, excellent news
12:46 PM phipli: for your entertainment, I will now go and weigh the double yoker we got the other day...
12:47 PM phipli: 70g
12:47 PM phipli: poor chicken
12:50 PM Contract_Pilot-A: https://www.youtube.com/watch?v=NcibPZH-6xY
12:50 PM Contract_Pilot-A: Cool..
01:34 PM CaptHindsight: we got snow
01:35 PM phipli: where abouts?
01:37 PM CaptHindsight: Chicago
01:37 PM CaptHindsight: ~1" just to make everything white
01:38 PM CaptHindsight: another Festivus miracle
01:41 PM phipli: statistically, it actually snows on Easter more often here
01:42 PM phipli: tends to snow more in the start of the year than the end
01:43 PM phipli: I like when it snows. Makes everything go at a slower pace. Get to walk to work, not get run over and not be told off for being late (because lots of people don't turn up)
01:43 PM CaptHindsight: we rarely get snows that late
01:48 PM JT-Shop: 70g is a nice one
01:50 PM gloops: theres a cross that mainly lays double yolkers, cant remember what its called now
01:52 PM CaptHindsight: https://www.atlasobscura.com/articles/found-a-carton-of-a-dozen-eggs-all-with-double-yolks
01:52 PM CaptHindsight: so not impossible
01:53 PM CaptHindsight: odds are one in a thousand trillion
01:54 PM gloops: they used to sell some at the local garage - big eggs, not all double yolks but a lot of them were, he told me it was a cross breed that was used for it, cant remember what
01:54 PM JT-Shop: someone from Macedonia wants me to send them a commercial invoice for some Mesa cards...
01:55 PM SpeedEvil: CaptHindsight: no, they're not
01:55 PM JT-Shop: she has not laid an egg today, usually by 11am she is done it's 2pm
01:55 PM SpeedEvil: CaptHindsight: thousand trillion if you assume (average probability of egg being double)^24
01:56 PM SpeedEvil: CaptHindsight: But it's correlated, not independant
02:02 PM gloops: https://www.ebay.co.uk/itm/White-Jersey-Giant-large-fowl-hatching-eggs-x6-extremely-rare-breed/173008245116?
02:14 PM jthornton: lol just found 5 eggs in the electronic panel, they had pulled the cardboard down
03:50 PM Wolf__: hmm, any guess to what the pressure angle might be on a Taiwan lathe change gears 1.25 MOD… 14.5 or 20?
03:51 PM archivist: should be/most likely 20
03:51 PM archivist: measure!
03:51 PM Wolf__: I was thinking about attempting to measure it lol
03:52 PM Wolf__: just not sure how
03:52 PM Wolf__: set up wise, not what to measure
03:54 PM archivist: I use a special microscope http://www.collection.archivist.info/searchv13.php?searchstr=travelling+microscope+swift
03:55 PM Wolf__: yeah, I dont have one of those and not really planning on adding one to the shop lol
03:55 PM archivist: anything with a cross hair and the ability to rotate
03:56 PM Wolf__: hmm, I think I have a loupe with a grid in it
03:56 PM Wolf__: somewhere...
04:01 PM `Wolf: or just load a photo in to cad software? https://i.imgur.com/l0uhwY0.jpg
04:08 PM archivist: Wolf__, yes speceally if you can see the centre line from gear middles at the contact point
04:08 PM Rab: `Wolf, you can measure angles in an image with this tool: https://github.com/hzeller/augenmass
04:10 PM Rab: Although it would probably help to have one or more of the gear center hubs in the picture for reference.
04:11 PM Wolf__: yeah, I could just pull one of the gears off and use a tripod or something to get the thing flat and centered
04:12 PM Wolf__: but really I dont think its matters too much because I’m 3d printing the replacement gears so I could just do a 2 layer test print of matching tooth count lol
04:12 PM Wolf__: and see if they match up
04:15 PM archivist: gimp tells me 20 ish
04:19 PM archivist: http://www.collection.archivist.info/archive/grabs/Screenshot-angle.png
04:29 PM Wolf__: I figured your rough guess would probably be right anyways =)
04:31 PM archivist: I just tipped whole drawing so they looked level with each other then grabbed a section and rotated and stopped when the tooth looked horizontal
04:37 PM Wolf__: simple enough
04:38 PM Wolf__: now to wait on rushgears.com to build me a cad/stl of the gear I need =)
04:40 PM Contract_Pilot-A: Yea, i need to order a timing pulley
04:41 PM archivist: or just buy the size you want from a standard gear company
04:42 PM Contract_Pilot-A: I think i need to go larger on the spindle motor and smaller on the drive gear
04:43 PM Contract_Pilot-A: Can hit 2200 RPM want 2500
04:43 PM Contract_Pilot-A: + a little more
04:45 PM Wolf__: archivist: rushgears.com has a online gear tool that will spit out a cad file of whatever gear you spec
04:48 PM Tom_L: Contract_Pilot, i just got some from sdp-si
04:53 PM Deejay: gn8
05:05 PM Contract_Pilot-A: Not sure what i want to do ont he spindle yet
05:06 PM Contract_Pilot-A: 1st thing is to get the VFD wire to the tormach BOB
05:06 PM Contract_Pilot-A: Guts hurting a bit had to take some dope!!
05:08 PM Contract_Pilot-A: Full dose!!! but getting better every day! 6 weeks being dependent on kid and wife yep they already complaining and less than a week i.
05:08 PM Contract_Pilot-A: in
05:49 PM jdh: what did you do
05:51 PM lunadabay: hi
05:54 PM lunadabay: anyone know if slow accel would cause issues with velocity when milling a circle? The machine goes 1000ipm in straight lines but is FAR slower with a circle.... like 500ipm
05:55 PM lunadabay: it's an Osai control, not linux btw
06:25 PM enleth: lunadabay: it could, yes
06:26 PM enleth: lunadabay: milling a circle requires accelerating and decelerating in a sinusoidal pattern
06:31 PM enleth: lunadabay: is the effect more pronounced on a small circle, while a large one mills faster?
06:38 PM lunadabay: we only tried about a 12" circle
06:40 PM lunadabay: It's a new router that we are buying, we went to check it out and it had really slow accel and decel. It also has a bit of a pause during change of direction. Plus tons of following error. Pretty bummed..... unfortunately we already put 35k down on it, otherwise i'd look elsewhere
06:40 PM lunadabay: supposedly they aren't done tuning it, but it seems like the servos might be underpowered.
06:41 PM lunadabay: i'm half tempted to make them keep the Osai control and i'll throw linux on it.
06:43 PM lunadabay: my mill doesn't seem to slow down at all, and it doesn't exactly have the best accel rate.
06:48 PM enleth: that is a rather large circle for a router to slow down on, I think
06:48 PM enleth: have you noticed how long a straight path needs to be for it to accelerate from a stop to 1000ipm?
06:59 PM -!- #linuxcnc mode set to +v by ChanServ
07:14 PM justanotheruser is now known as justan0theruser
07:34 PM lunadabay: no, they were giving us some BS numbers, i havent gotten the real accel rate yet.
07:35 PM lunadabay: it's really pathetic when it gets to a corner on a square or diamond
07:37 PM Tom_L: this is not from linuxcnc control is it?
07:37 PM Tom_L: rather their control
07:38 PM enleth: lunadabay: try to get a peek at the servos and drives
07:39 PM enleth: snap a photo of the nameplates, look them up online
09:57 PM Wolf__: hmm wtf, i have the module size wrong for these gears
09:59 PM Wolf__: or not… cad file was wrong :/
10:04 PM Wolf__: lmao… helps if download correct one
10:22 PM CaptHindsight: Happy Christmas Everyone!
10:29 PM Tom_L: Merry Christmas
10:49 PM CaptHindsight: Tom_L: everyone must be as snug as bugs in rugs waiting for Santa
10:50 PM Tom_L: apparently
10:50 PM CaptHindsight: I wonder if any smart kids are getting suspicious with there being two Santa trackers ...
10:50 PM Tom_L: was gonna work on the mill a bit but not much i can do until i get stuff milled flat
10:51 PM CaptHindsight: that aren't in sync
10:51 PM Tom_L: heh
10:51 PM Wolf__: need a mill to make the mill eh?
10:51 PM CaptHindsight: yeah, no welding here today
10:52 PM CaptHindsight: I probably would have spent half the time grinding and redoing
10:52 PM Tom_L: he's been kinda busy so i told him i was in no hurry
10:52 PM CaptHindsight: we got just enough snow to make everything white, except the roads
10:55 PM Tom_L: dry here
10:55 PM CaptHindsight: https://santatracker.google.com/intl/en/tracker.html
10:55 PM Tom_L: 20F
10:55 PM CaptHindsight: yeah cold here to
10:56 PM CaptHindsight: near 0F at night
10:56 PM CaptHindsight: -18C
10:57 PM CaptHindsight: did anyone get their Amazon orders on time this week?
10:58 PM Wolf__: a few of them…
10:58 PM CaptHindsight: mine are stalled minutes away
11:09 PM CaptHindsight: ok back to xmas stuff
