12:30 AM pink_vampire: what move?
12:30 AM XXCoder: part
12:30 AM pink_vampire: hope not
01:15 AM pink_vampire: https://imgur.com/gallery/cILGooO
01:15 AM pink_vampire: 3 more to go
01:17 AM XXCoder: yayy
01:18 AM XXCoder: repeatable fixture I see :)
01:19 AM pink_vampire: the fit is very nice
01:22 AM pink_vampire: I don;t have stop for the side, BUT probe make you happy
01:23 AM XXCoder: ahh indeed
01:23 AM XXCoder: im so used to no probe setups.
01:23 AM XXCoder: do it take account of angles also?
01:25 AM pink_vampire: you can, but the vise is trim to be perfect
01:25 AM XXCoder: interesting. but yeah better setup, the better part.
01:25 AM pink_vampire: so i just push it against the back jaw
01:39 AM pink_vampire: 2 more to go
01:58 AM Deejay: moin
01:58 AM pink_vampire: moin

05:25 AM XXCoder: nice
05:56 AM Tom_L: morning
05:57 AM XXCoder: yo
05:57 AM jthornton: morning
05:57 AM pink_vampire: hi Tom_L
05:58 AM Tom_L: jt, gettin any weather?
05:58 AM Tom_L: we're supposed to but nothing yet
05:58 AM jthornton: yea been raining all night
05:58 AM pink_vampire: Tom_L: just now it is clicked in to my mind Tom_L = Tom Lipton
05:59 AM Tom_L: nope
05:59 AM pink_vampire: O_o
06:00 AM XXCoder: is it you tommy lee?
06:01 AM Tom_L: nope
06:03 AM jthornton: lol
06:05 AM pink_vampire: maybe the oLd Tommy?
07:23 AM pink_vampire: https://i.imgur.com/VjW3gkp.png
07:28 AM pink_vampire: my new setup for the mill
07:29 AM pink_vampire: XXCoder: Tom_L jthornton
07:32 AM jthornton: what are you doing?
07:33 AM pink_vampire: 5 axis axis machining on g0704 with 4+1 configuration
07:39 AM jthornton: using the main spindle as a rotary axis?
07:39 AM pink_vampire: correct
07:48 AM jthornton: for a good laugh https://forum.linuxcnc.org/38-general-linuxcnc-questions/36611-how-to-install-softwares#134267
07:49 AM pink_vampire: LOL
07:52 AM jthornton: pl7i92 is from another planet I think
07:55 AM pink_vampire: why?
08:01 AM jthornton: the things posted are strange at best
08:03 AM pink_vampire: link?
08:12 AM _unreal_: ok... finally!
08:12 AM _unreal_: got a motor controller hooked up. about to plug it in and see if it burns up on me :)
08:12 AM _unreal_: everything SHOULD be correct
08:12 AM pink_vampire: don't let the smoke out
08:13 AM _unreal_: ok... plugged it in and motors are hissing as expected. chopper noise
08:13 AM jdh: or if you do, set the camera for slo-mo first
08:14 AM _unreal_: almost sounds like static in an old TV
08:14 AM jdh: damn you are old
08:14 AM _unreal_: I did just turn 40
08:15 AM _unreal_: So I wonder what would be faster just to rig up a TEST?
08:16 AM _unreal_: arduino with grbl or my old pentium 1 laptop with turbocnc
08:16 AM _unreal_: just to plugin set motors and move...
08:23 AM jthornton: youngsters lol
08:32 AM jdh: yep
08:50 AM _unreal_: I'm going to order one of these https://www.aliexpress.com/item/32980749345.html?spm=a2g0o.cart.0.0.31e43c00Tdeapv
08:56 AM pink_vampire: why?
09:00 AM jdh: for relatively inexpensive disappointment
09:01 AM pink_vampire: LOL!
09:01 AM jdh: please take notice : that the laser head is easily-consumed products ,so we promise to supply again within three month if the laser head is Inhuman damage.so if you laser head is Inhuman damage ,please do not give negative comment thanks for your support.
09:02 AM pink_vampire: but what you can cut with 1W?
09:03 AM jdh: please exit antivirus software before operating the machine.
09:03 AM pink_vampire: WTF
09:09 AM veek: music https://www.youtube.com/watch?v=lo2R6-nKIZE
09:22 AM Tom_L: jthornton, never heard of geany
09:25 AM Tom_L: noob's complete drill set for $10 https://www.aliexpress.com/item/3Pcs-Metric-Spiral-Flute-The-Pagoda-Shape-Hole-Cutter-4-12-20-32mm-HSS-Steel-Cone/32689427256.html?spm=2114.search0104.3.7.63d82884gjRytV&ws_ab_test=searchweb0_0,searchweb201602_2_10065_10130_10068_10890_10547_319_10546_317_10548_10545_10696_453_10084_454_10083_10618_10307_537_536_10059_10884_10887_321_322_10103,searchweb201603_52,ppcSwitch_0&algo_expid=50eeb075-652c-4d2d-a194-de1414
09:36 AM _unreal_: looks like success blew up an other motor controller
09:36 AM _unreal_: no fucking clue why
09:37 AM _unreal_: this machine I build has blown every motor controller I've ever connected to it
09:37 AM _unreal_: I dont get it
09:37 AM Tom_L: stop adding new ones until you figure out why
09:37 AM _unreal_: no is no expination
09:38 AM _unreal_: all the motors are 10 ohms
09:38 AM _unreal_: each rated different amps 1 1.2 1.4
09:38 AM _unreal_: I can step them JUST fine
09:39 AM _unreal_: walking power over the wires no issue
09:39 AM _unreal_: Tom_L, its more of a bad luck thing
09:39 AM _unreal_: this @#$@#$ machine has a bad luck Ora around it.
09:40 AM _unreal_: the last motor controller that i had setup was working great till I went to clean up the wires and tie everything down. only to have a wire magiclly slip. and burned the motor controller.
09:42 AM Tom_L: yeah you don't wanna have disconnects while powered
09:42 AM _unreal_: I mean litteraly this cnc machine ONLY this one has this magic about it
09:43 AM _unreal_: I have everything STUPID proofed and it still keeps succedding in fucking drivers
09:43 AM _unreal_: ! think I just found the issue
09:44 AM _unreal_: thermal paste seems to have oozed out from the heat sink area after it got worm. the pins from the controllers has paste touching some of them....
09:45 AM _unreal_: JUST magic
09:45 AM _unreal_: AT this poing thats it I'm not spending money on controllers any more I'm not resting till I BUILT a controller and make this fucking thing work
09:46 AM Tom_L: or get a gecko203 which is nearly indestructible
09:51 AM JT-Shop2: yea 203v or the smaller one is the way to go
09:51 AM Tom_L: jthornton, never heard of geany
09:51 AM Tom_L: you like it?
09:53 AM _unreal_: Tom_L, the motors are all unipolar
09:55 AM jthornton: so far I do, it shows the white space if you want and is pretty light weight
09:57 AM Tom_L: i need something better for wheezy on the mill
10:00 AM jthornton: I'm putzing around building Lubuntu minimal install and it comes with leafpad, wow is it crap! open a file on the LAN and when you save it you get a blank file...
10:00 AM _unreal_: So back to my original plan.
10:00 AM Tom_L: nice
10:00 AM _unreal_: going to build individual motor controllers
10:00 AM _unreal_: so I can get each of these fucking steppers working and nothing can CROSS fuck anything else
10:01 AM Tom_L: i mapped the mill to my windows cad cam directory so i can just pull the files in from there but once in a while i need to change a feed or such but gedit kinda sucks on wheezy
10:04 AM jthornton: yea gedit has gone to crap
10:04 AM jthornton: developers think everything has to be like a eye phone I guess
10:05 AM Tom_L: idespise iphone
10:05 AM jthornton: yea they are nothing but crap
10:06 AM Tom_L: been using galaxy s series since about 3 or 4 i think
10:07 AM jthornton: I'm still using an old one and will continue till it dies
10:07 AM Tom_L: i finally moved my business line to an s5
10:07 AM Tom_L: land line was costing way too much
10:08 AM _unreal_: I've always been a fan of nano for editing
10:08 AM Tom_L: that way the secretary (if i had one) could play candy crush while painting her nails
10:08 AM _unreal_: jthornton, your or it which ever comes first lol
10:09 AM rene_dev_: Use pluma, it looks like the old gedit
10:10 AM Tom_L: i'll take a look at it thanks
10:10 AM rene_dev_: Why wheezy. It’s eol for 12 months
10:10 AM _unreal_: any one know of any motor controllers like this that are UNIPOLAR not bipolar ? https://www.ebay.com/p/Tb6600-0-2-5a-CNC-Controller-Stepper-Motor-Driver-NEMA-17-23-Tb6600-1-Axis-2/2132923104?iid=292273542799
10:11 AM Tom_L: the mill works and it's an old MB
10:11 AM Tom_L: that's why
10:11 AM Tom_L: if it ain't broke....
10:11 AM sync: well, it is broken, since it is EOL
10:11 AM rene_dev_: Replace them with bipolars. They are better in every way.
10:12 AM _unreal_: I will never ever ever replace the motors on this machine
10:12 AM _unreal_: I'd buy a new machine before Id waste the money
10:12 AM _unreal_: its a home made machine. very strong. but the motor mounts are a night mare to deal with
10:13 AM rene_dev_: Some you can rewire to bipolar
10:13 AM _unreal_: they are all 5 wire
10:13 AM _unreal_: unipolar
10:13 AM _unreal_: so no I can not
10:13 AM rene_dev_: Then good luck finding a drive :D
10:13 AM _unreal_: I'm at a BREAK the bad luck spirit that has infected this machine
10:13 AM _unreal_: point....
10:14 AM _unreal_: pissis me off to no end that no one sells unipolar drivers
10:14 AM sync: that's the reason to switch to bipolar motors
10:15 AM _unreal_: as I said I'm not switching the motors on this THIS machine...
10:15 AM _unreal_: the new one for work. YES its bipolar
10:28 AM Jymmm: _unreal_: there are meds for that ;)
10:38 AM jthornton: Tom_L: geany can show the line numbers in a column so that makes searching for a line much faster for me
10:39 AM Tom_L: what gets me about gedit is the 'find' only finds one then goes away. no 'find next'
10:40 AM Jymmm: Tom_L: CTRL+G (aGain)
10:41 AM Tom_L: i'd rather the window just stay up. too many things to remember as it is..
10:42 AM Tom_L: i've got probably 10 editors i use currently
10:43 AM Jymmm: delete 9 of them
10:43 AM Jymmm: problem solved
10:43 AM Tom_L: naw
10:43 AM Tom_L: gedit may be one of the 9 :D
10:44 AM Jymmm: CTRL+G is common to most editors
10:44 AM Jymmm: and some browerses too
10:49 AM pcw_home: the gedit I'm using leave the search window up and has up/down arrows for find next/find prev
10:49 AM Tom_L: hmm
10:49 AM Tom_L: this is on wheezy
10:50 AM jthornton: yea they dropped that in wheezy and went with no menu
10:50 AM pcw_home: Yeah this is newer
10:51 AM jthornton: hmm maybe they put that back...
10:51 AM jthornton: tried to make a kernel deb but failed so make again and just install and see
10:51 AM Jymmm: or maybe it's an option that can be enabled?
10:52 AM Jymmm: ...in preferences
10:53 AM jthornton: maybe it is check it out and let us know
10:53 AM Tom_L: i will next time i'm out there
10:54 AM jthornton: hmm it's overcast here and I think I heard the nap time bell ring
10:55 AM Tom_L: i'm quite sure i heard it
10:56 AM Jymmm: NAh, that was the brunch bell
10:56 AM Tom_L: they pretty much go hand in hand
11:02 AM Jymmm: Is there some ghetto way to taper in a 3.125" pipe to 3" diameter, about 3" long?
11:04 AM Tom_L: further explination needed
11:04 AM Tom_L: is the pipe threaded?
11:04 AM Tom_L: oh you want it smaller
11:04 AM Jymmm: The pipe overall length is 36", I just need to taper in the end part
11:05 AM Tom_L: does it need to hold pressure?
11:05 AM Tom_L: cut a + in the end and pinch it together
11:05 AM Tom_L: if it isn't a pressure line etc
11:05 AM Jymmm: No, just being used for flue pipe
11:06 AM Tom_L: how thick is the pipe?
11:06 AM Jymmm: 1/8 wall
11:06 AM Tom_L: get a needle nose pliers and twist the end of the pipe like they do when they knurl it
11:06 AM Tom_L: forget that on .125"
11:06 AM Jymmm: =)
11:06 AM Tom_L: cut the +
11:07 AM Tom_L: or maybe a couple at 45 deg
11:07 AM Tom_L: or just butt the ends and weld it
11:08 AM Tom_L: that might be your best bet
11:08 AM Jymmm: That's the issue, a chinmet liner flue tube needs to be attached to it.
11:08 AM Jymmm: I'll probably just have to hit a muffler shop
11:08 AM Tom_L: maybe a napkin cad drawing would be in order
11:09 AM Jymmm: Nah, it's just the pipe I have, I'll just go get/buy the proper size, only need 5"
11:09 AM Tom_L: yeah they could probably do it
11:10 AM Valduare: https://www.amazon.com/gp/product/B07MX5DWF3/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 any foreseeable issues with one of these for spindle encoder?
11:16 AM pcw_home: No index...
11:21 AM phipli: jthornton, yeah, I use Geany some
11:29 AM Jymmm: What a cute little plasma cutter... https://youtu.be/eOou95HpQ9g?t=16
11:31 AM pink_vampire: AWWWWWWWWWWW paint it pink and give it to me
11:31 AM Deejay: hrhr
11:37 AM phipli: Hope they flushed the cylinder properly first... well, I guess they did given they uploaded the video
11:40 AM pink_vampire: the gas in the tank help to start the cut faster
11:56 AM Valduare: pcw_home ya i was thinking of that as well
12:22 PM _unreal_: I love press n peel blue
12:22 PM _unreal_: so for shits and giggles. I'm building a new sla7024 motor driver
12:23 PM Tom_L: i got a whole packet i'll never use
12:23 PM Tom_L: had better luck with photo paper
12:23 PM _unreal_: really?
12:23 PM _unreal_: what issues have you had?
12:23 PM Tom_L: i didn't care for it
12:23 PM Tom_L: crappy traces
12:23 PM _unreal_: ..... ok WHAT turned you off
12:23 PM _unreal_: what was your process?
12:24 PM Tom_L: i dunno, it's been quite a while back
12:24 PM Tom_L: hardly do any etching now
12:24 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/etching/etch6.jpg
12:25 PM _unreal_: in a nut shell this is what I do. single side. pcb... take paper. PRINT your artwork
12:25 PM Tom_L: those were photo paper
12:26 PM _unreal_: once you have your artwork laser printed on paper. Cut a section of the blue pnp stick it to the paper with scotch tape a little over sized to your artwork.
12:26 PM _unreal_: run it through the printer again. now you have toner on the peel side.
12:26 PM Tom_L: i know the steps
12:26 PM _unreal_: mine are different
12:26 PM _unreal_: unless you have the same setup
12:26 PM phipli: Tom_L : I've been getting a couple of boards made
12:26 PM phipli: nice to have fancy boards instead of my homemade stuff
12:26 PM Tom_L: yeah
12:27 PM Tom_L: unless you're in a hurry it doesn't cost any more
12:27 PM _unreal_: after printing. I take tape and stick to the prepped PCB.. i KNOW YOU KNOW... next I dont use an IRON. I have a laminaotor
12:27 PM phipli: Yeah - I was milling prototypes, but to be honest I haven't done that in a while
12:27 PM _unreal_: so I take 2 clean peaces of paper. put the PCB between them. and run it
12:28 PM _unreal_: flip and run. I know my laminator heats top and buttom but I've found that I get better results if I flip the board and run it a few times per side. you know the rest....
12:28 PM _unreal_: I get perfect prints very fine pitch
12:29 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/temp/tiny/tinyboard2.jpg
12:29 PM Tom_L: sot23-6
12:29 PM Tom_L: that's pretty fine
12:29 PM Tom_L: 3 traces under it
12:30 PM Valduare: dry film photo resist is great stuff
12:30 PM _unreal_: Valduare, that is the best IMO
12:30 PM _unreal_: but not as cheap
12:32 PM _unreal_: Tom_L, how do you do your transfer?
12:32 PM Tom_L: iron
12:33 PM _unreal_: heh
12:33 PM PL7icnc: Good Sunday to all
12:33 PM _unreal_: go to hell ;)
12:33 PM Tom_L: kinda un called for
12:33 PM Valduare: there's always some seller from bulgaria selling dry film photo resist on ebay for dirt cheap
12:33 PM PL7icnc: Oh Hard Language here
12:34 PM Valduare: I want to play with spincoating pcb with a photo resist too
12:35 PM _unreal_: ! i forgot this dbl sided PCB is 4mill copper OMG..
12:35 PM PL7icnc: Q: will there after the Wheezy is now offical going down a Debian9 DVD with 2.8 out
12:35 PM Valduare: quite fun to be able to throw pcb on the mill drill a bunch of holes, plate them then dry film it and etch in-house
12:35 PM Tom_L: PL7icnc they are working on that
12:35 PM PL7icnc: Thank you
12:35 PM Tom_L: no time frame set in stone
12:35 PM _unreal_: Valduare, I'd be doing that if I could get a motor controller working on my cnc machine
12:35 PM Tom_L: it's a volunteer effort
12:35 PM phipli: Valduare - how do you plate the holes at home?
12:36 PM Valduare: motor controller or do you mean stepper driver?
12:36 PM PL7icnc: You may know I am the New German CNC Teacher in replace of the Decised member here
12:36 PM Valduare: phipli india ink with graphite powder. squeegy the solution on the board to push through all the holes then shopvac it from the other side then bake 150c for 10 min in toaster oven
12:37 PM Valduare: then steel wool the faces of the board clean and throw in plating tank
12:38 PM CaptHindsight: electroplating at home is not too difficult
12:38 PM _unreal_: years ago I purchased this 4mill dbl sided PCB that is paper thing PCB board
12:38 PM _unreal_: flexy like hell but it was dirt cheap when I purchased it
12:38 PM phipli: Nicer way of doing vias than drilling a hole and sticking a chopped off leg through it :p
12:38 PM Valduare: CaptHindsight nope that part is dead easy, its the getting 100+ holes all activated thats the trick hah
12:38 PM _unreal_: I think it was like 50 8x8 sheets 4mill copper for $10 on ebay
12:39 PM _unreal_: I think I purchased it in 2002
12:39 PM _unreal_: I still have a ton of it
12:39 PM Valduare: phipli for pinning vias i use little brass push pins from sewing store
12:39 PM Valduare: have a nice tiny head on them 1mm
12:39 PM Valduare: fits nice on 1.2mm via pads etc
12:40 PM PL7icnc: This Weeks Test moves with the 5Axis on tb6600
12:40 PM phipli: I keep a pot of chopped off resistor legs. Diode legs are nice and big, but I don't use many diodes
12:40 PM phipli: LED legs are probably about the right size... but again, don't use as many as resistors
12:41 PM CaptHindsight: PL7icnc: ichs made it sound like he volunteered at the school
12:41 PM PL7icnc: How do you guys Level the PCB board and How deep is the cut on paper
12:41 PM PL7icnc: CaptHindsight, Yes
12:41 PM Valduare: no leveling
12:41 PM Valduare: face spoilboard and then use masking tape on it
12:41 PM CaptHindsight: PL7icnc: especially after the 3 years as a park ranger
12:41 PM _unreal_: I just ordered this https://www.aliexpress.com/item/-/32980749345.html?spm=a2g0o.cart.0.0.31e43c00Tdeapv
12:42 PM PL7icnc: CaptHindsight, i dont know him
12:42 PM _unreal_: cant find an equal to it for the price and NEW
12:42 PM Valduare: masking tape on backside of pcb, and masking tape on the spoilboard. some superglue and activator and press it down. it holds the pcb flat to your faced spoilboard
12:42 PM Valduare: _unreal_ wish.com has those for 40ish now and then
12:43 PM PL7icnc: CaptHindsight, i try to get over this all But i got only a 1 year Contract
12:43 PM PL7icnc: CaptHindsight, and below 1000 Students he got well over 8k a year
12:44 PM PL7icnc: the 3D-printers are the biggest concern at the moment
12:44 PM PL7icnc: about 50 to be put together
12:45 PM CaptHindsight: 3d printers = FDM or?
12:45 PM PL7icnc: all Anet A10 Ender3 Clones
12:46 PM PL7icnc: Mr "Ich" has levt 7000USD to be spend on CNC stuff
12:46 PM phipli: PL7icnc, for the school?
12:46 PM PL7icnc: Yes
12:47 PM phipli: That was good of him
12:47 PM PL7icnc: 5 Education Centers i Shoudt say
12:47 PM _unreal_: Valduare, not cheaper they dont include shipping
12:47 PM PL7icnc: He got a Big Budget from haas CNC JohnDeer Siemens ....
12:48 PM PL7icnc: I'am Off will try to keep up in Forum as i Do learn More and More how to Use Things
12:49 PM _unreal_: freaking hell I may have to get new etching solution :/
12:49 PM _unreal_: so much copper I think its zapped my etchent
12:49 PM _unreal_: then again. I etch in a ziplock bag with a small amount
12:56 PM Jymmm: _unreal_: let me know how your laser works for you
12:56 PM _unreal_: there just tossed some fresh juice in the bag
12:56 PM _unreal_: Jymmm, ?
12:56 PM _unreal_: thinking of getting one?
12:58 PM _unreal_: ?
12:58 PM Jymmm: _unreal_: Maybe
12:59 PM _unreal_: and now I remember why I have not made very many pcbs with this dbl sided PCB I have. its so damn thick
12:59 PM _unreal_: and to thin to mill
12:59 PM _unreal_: copper thick
01:03 PM _unreal_: good god. standard pcb's with 1-2mil copper etch in 10-15min. this has been over an hour now
01:03 PM _unreal_: 4mill
01:10 PM _unreal_: sigh....
01:16 PM _unreal_: finally I'm starting to see a little of the fiberglass at the edges
01:17 PM CaptHindsight: keep the etchant flowing
01:41 PM jthornton: phipli: hey
01:42 PM phipli: evening jt
01:42 PM jthornton: how's it going on your side of the pond?
01:43 PM phipli: muddling on
01:43 PM jthornton: wiring up the garden shed to be converted to a coop just got the LAN going
01:43 PM phipli: Spent the last few weeks doing jury duty
01:43 PM phipli: getting more birds?
01:43 PM jthornton: oh fun, capitol case?
01:44 PM phipli: or are they just moving into a luxury pad?
01:44 PM phipli: capitol?
01:44 PM jthornton: still want to get some Cinnamon Queens
01:44 PM jthornton: murder and such
01:44 PM * SpeedEvil best GPL violation.
01:44 PM phipli: ah right - yes, but they gave me a fraud
01:44 PM jthornton: I hope to integrate both flocks at some time without too much trouble
01:45 PM SpeedEvil: ^bets
01:45 PM jthornton: wife did jury duty for a murder case, I'd hate to have to do that
01:45 PM CaptHindsight: mans laughter
01:46 PM jthornton: just moving the automagic chicken door over there now, it's been working on my desk for a long time now
01:46 PM jthornton: be back in a bit
01:47 PM phipli: sure thing
01:47 PM CaptHindsight: what is the best way to get out of jury duty?
01:47 PM phipli: jthornton, let them see each other for a while before you integrate them
01:47 PM phipli: CaptHindsight, commit a crime
01:47 PM jthornton: yea that's the plan to have them share a common chain link fence for quite some time
01:49 PM phipli: jthornton, they're worse than you imagine
01:49 PM CaptHindsight: criminals make for good jurors, they have experience with the system
01:49 PM phipli: our quietest bird became an evil, nasty horrible beast
01:49 PM * SpeedEvil got out by explaining I would be able to properly concentrate for 5 minutes at a time some days. :/
01:50 PM phipli: CaptHindsight, but if you've commited a crime in the recent past you're not able to be on a jury (here)
01:50 PM CaptHindsight: "I kin tell em if theyruh guilty by justuh lookinin their eyes"
01:51 PM phipli: No, we had multiple people that thought that
01:51 PM phipli: they don't trim them out
01:52 PM jthornton: really a big change in her?
01:53 PM CaptHindsight: phipli: if convicted of a felony here you're marked for life even after your time is served
01:53 PM CaptHindsight: we have a revenge system vs rehabilitation
01:53 PM phipli: jthornton, only with regards to the new birds
01:53 PM phipli: she wouldn't leave them be
01:53 PM phipli: every time they went to food or water, even if she had her own
01:54 PM phipli: she'd pull bunches of feathers out or go for their face
01:54 PM phipli: was worried she'd have an eye out
01:54 PM jthornton: wow serious resource hog then
01:54 PM phipli: got as far as guying those peck guard things, but then she fell ill before we fit them
01:55 PM jthornton: did she recover?
01:55 PM phipli: ultimately no - she lasted about 4 more months]
01:55 PM phipli: she's the one that everything went wrong
01:56 PM phipli: all sorts of horrible issues with her innards - any other bird would have been dead in days
01:56 PM phipli: but she was the terminator of chickens
01:56 PM jthornton: I wonder if being sick made the behavior change
01:56 PM phipli: jolly little thing as long as one of the young ones wasn't in sight :)
01:56 PM _unreal_: still has not fully finished etching
01:57 PM phipli: jthornton, she was bottom of the pecking order - every time a sister died she got promoted...
01:57 PM phipli: then these new impostors turned up...
01:57 PM jthornton: how many do you have now?
01:57 PM phipli: so she got very angry
01:57 PM phipli: atm 3
01:57 PM phipli: one of the 4 originals
01:57 PM phipli: and two new(ish) ones
01:58 PM jthornton: I still have the 8 hens, dunno if I told you about giving the egg eater to my neighbor or not
01:58 PM phipli: you mentioned yes
01:58 PM phipli: we're having trouble with one eating eggs atm
01:58 PM CaptHindsight: how old do they live in captivity?
01:58 PM jthornton: she is happy and I'm happy and the rooster is happy
01:58 PM phipli: CaptHindsight, depends - can be up to ~10 years
01:58 PM jthornton: they can live for a long time sometimes
01:59 PM phipli: CaptHindsight, the ones bread to lay lots of eggs tend to be cancer / problems down there prone
01:59 PM phipli: so most of those ones don't make it as long
01:59 PM phipli: but more old fashioned breads do better and the occasional one lasts for ages
02:00 PM phipli: bred*
02:00 PM phipli: heh
02:02 PM jthornton: the Cinnamon Queens are a cross between the Rhode Island Red and Rhode Island White
02:03 PM _unreal_: so close
02:05 PM _unreal_: the copper must not have a uniform thickness on this pcb clad that I have. because some spots take way longer then others
02:06 PM _unreal_: one side of the board has been fully etched for at least 30min. the other side it has some spotty areas that are still going
02:06 PM jthornton: my neighbor got tired of predators killing her chickens and finally put up a fence and put a hot wire on it
02:07 PM jthornton: she had 30 black hens and is down to 1 black one, also she has lost a lot of other breeds
02:08 PM _unreal_: sounds like she needs to invest in a bug with a night vision scope
02:08 PM _unreal_: bug=gun
02:08 PM _unreal_: or a nice pellet gun
02:10 PM _unreal_: everything has been etched but one stupid area. that is bridging some traces
02:10 PM _unreal_: its 99% done
02:16 PM JT-Shop: she works nights...
02:22 PM JT-Shop: oh and she carries a 9mm in her pocket and a 30-06 on the porch :)
02:25 PM net|: https://netpipe.ca/classifieds if you want your village / town added let me know
02:25 PM phipli: JT-Shop, she just needs bigger chickens that fight back :)
02:26 PM _unreal_: ok board is done and lines are sharp as hell
02:26 PM Tom_L: don't cut yourself
02:26 PM _unreal_: no promises
02:27 PM _unreal_: LOL the copper traces are as thick as the PCB's fiberglass core
02:29 PM JT-Shop: phipli: she had 4 turkeys but the toms were killing the chickens by standing on them
02:29 PM phipli: geese?
02:30 PM Tom_L: there was a place around here that raised ostriches
02:30 PM JT-Shop: no geese
02:31 PM JT-Shop: she has a Great Pyrenees but doesn't do his job too well... spends his time fighting off the old man's dogs from the other side of her
02:35 PM phipli: JT-Shop, http://stuffandnonsense.elephantandchicken.co.uk/?p=531
02:37 PM JT-Shop: I'd bet Monique would do that too, she still flys up to my shoulder and rides around
02:38 PM phipli: Yeah, Chompsky jumps on me if I stand near the wall
02:38 PM phipli: she even tries to jump on you when you're way too far away
02:38 PM phipli: she doesn't let things like physical limitations get in the way of trying
02:39 PM JT-Shop: lol
02:45 PM JT-Shop: http://gnipsel.com/images/chickens/12x16-coop/coop-door-01.jpg
02:45 PM JT-Shop: http://gnipsel.com/images/chickens/12x16-coop/coop-door-02.jpg
02:46 PM phipli: Went to a beer festival on Friday in a Steam Locomotive Roundhouse... forgot to take any photos of beer or trains
02:46 PM phipli: http://stuffandnonsense.elephantandchicken.co.uk/?p=537
02:46 PM phipli: oooh, posh. A touchscreen :)
02:46 PM JT-Shop: the lower one looks like my Cocoa
02:46 PM phipli: Labrador?
02:47 PM JT-Shop: I found it easier to program than switches
02:47 PM JT-Shop: kinda a mix
02:48 PM phipli: A lot of very friendly dogs there
02:49 PM phipli: The one in the top middle was happily walking about with its owner and every time he stopped, it sat down almost on his feet and spent its time watching him, or other people walking past
02:49 PM JT-Shop: well trained pup
02:50 PM phipli: What is the screen - a tablet?
02:50 PM phipli: or a screen plugged straight into the RPi?
02:50 PM JT-Shop: no, it's a RPi touch screen
02:52 PM JT-Shop: https://www.amazon.com/SmartiPi-Official-Raspberry-Touchscreen-Display/dp/B01HV97F64/ref=sr_1_10
02:53 PM JT-Shop: https://www.amazon.com/Raspberry-Pi-7-Touchscreen-Display/dp/B0153R2A9I/ref=pd_bxgy_147_img_2/144-5586036-3110540?_encoding=UTF8&
02:55 PM phipli: I have one of the screens, but I've not used it for anything - parents got it for me for christmas
02:55 PM phipli: and my brother
02:55 PM phipli: set my brothers up for him
02:58 PM JT-Shop: I used PyQt for the GUI part
02:59 PM phipli: I was playing with QT a bit the other day
02:59 PM phipli: installed it at work as well
02:59 PM phipli: might start using it for things (I generally tried to use visual studio because that was what our software department used... but then they split our software team off into another division of the company and we effectively don't even work for the same company any more)
03:00 PM JT-Shop: Qt with C++?
03:01 PM phipli: yeah
03:01 PM JT-Shop: I've never done much with C++, can't find a reason to learn it lol
03:01 PM phipli: thinking of using https://eigen.tuxfamily.org/dox/ and https://en.wikipedia.org/wiki/OpenMP
03:01 PM JT-Shop: Python works so far for me
03:02 PM phipli: Truth is I muddle along in everything
03:02 PM phipli: don't do enough of anything in particular to be really fluent
03:02 PM phipli: but have done enough of everything that generally I can muddle through in many languages with a bit of googling
03:03 PM JT-Shop: I think I'm pretty good with Python after using it for this long...
03:03 PM phipli: Bad at everything basically :)
03:03 PM JT-Shop: I even have a copy of Peter Norths Assembly Language book
03:03 PM phipli: Arduino C is about the only thing I program in most weeks
03:04 PM phipli: heh - I've not done assembly since... 10 years ago I wrote something to display text on a home made LED matrix
03:04 PM JT-Shop: I've done a fair bit of C for Arduino but like the RPi better now
03:05 PM phipli: I mostly use these now : https://www.aliexpress.com/item/32966381920.html
03:05 PM phipli: in their various forms
03:06 PM phipli: https://www.aliexpress.com/item/32688079351.html
03:06 PM phipli: that second link includes a usb interface and can be programmed straight from the Arduino IDE with no extra hardware
03:09 PM JT-Shop: I finally ordered something from aliexpress the other day
03:09 PM phipli: I don't get much from there - tend to only use it when I'm ordering a load of electronics from a wholesaler, or some tat that I don't care if it never arrives
03:09 PM JT-Shop: I have some esp8266 boards I think
03:10 PM JT-Shop: lol
03:10 PM JT-Shop: I just got some m3 standoffs and m3 screws
03:10 PM JT-Shop: tried to order some 24v power supplies but that must be part of the tarriff thing
03:10 PM phipli: but surely they'll confiscate them at customs for being metric?
03:11 PM JT-Shop: lol
03:12 PM phipli: are the tariffs impacting you much?
03:16 PM JT-Shop: no, I have not had much work lately so it don't matter to me...
03:16 PM JT-Shop: most of the work I do is programming PLC's any more
03:16 PM JT-Shop: hmm someone snuck in and laid an egg
03:19 PM andypugh: JT-Shop: Was it a bird, a reptile, a monotreme or a dinosaur?
03:20 PM andypugh: (I am discounting the possibility of fish, as they tend not to lay eggs around buildings)
03:20 PM jthornton: they sorta resemble a dinosaur but I've not seen any lately except the ones in the swamp
03:21 PM andypugh: I have a theory that Scottish people are montremes. They seem to have pouches, they appear to suckle their young, but they sell scotch eggs in shops, so presumably they also lay eggs.
03:21 PM jthornton: lol
03:21 PM jthornton: after closer examination it turned out to be 3 eggs all perfectly lined up so the camera only saw the front one
03:23 PM phipli: so we're looking for a cross-eyed dinosaur?
03:23 PM en1gma: i have arduino r3, cnc shield ver3.0 (grbl 0.9j), drv8825's (for X and Y as i have no Z). im having problems homing it with universal gcode sender, grbl panel and grbl windows 10 config tool
03:24 PM en1gma: i know its not linuxcnc exactly but i not doing anything like a cnc. i doing a sat dish aiming at stars :)
03:24 PM en1gma: i only have an X and Y axis. would that stop a homing cycle from starting or completing as i dont have a Z
03:24 PM andypugh: Hi en1gma. You are in the wrong place. I am not saying that we will necessarily be inwilling or unable to help, but we speak LinuxCNC here (which is basically an alternative to GRBL)
03:25 PM en1gma: i could download and and run a linuxcnc live but i think it might be a little too much for what i going to be doing
03:25 PM TurBoss: try #arduino
03:25 PM andypugh: But, lasers seem to work with GRBL and don’t have a Z axis
03:26 PM en1gma: oh so let me looks for lasers on yt. maybe there will be some homing guides or something. thanks
03:26 PM andypugh: You should find some GRBL-savvy folk on #octoprint too
03:26 PM phipli: enlgma - all you need is a serial connection to the board and to send the commands
03:26 PM phipli: it might be simpler to ditch all the bespoke software and send the g-codes
03:27 PM andypugh: It might well be that you are sending a home-Z command by mistake.
03:31 PM en1gma: i was using only using the arduino ide and sketches with commands in there until i got g-code working. i do think i will need an "Absolute" system in the end since i will be picking stars/sats and incremental wouldnt be to good for that
03:34 PM en1gma: brb. gonna reboot to ubuntu. getting out of windows 10
03:39 PM andypugh: en1gma: We don’t actually mind people using Windows to log in here :-)
03:41 PM en1gma: :)
03:48 PM XXCoder: jthornton: agreed gedit is shit now, used to be quite good.
03:49 PM CaptHindsight: https://en.wikipedia.org/wiki/Editor_war
03:50 PM andypugh: I am using Geany everywhere now.
03:50 PM XXCoder: installing now
03:50 PM andypugh: It’s good enough, without being too good.
03:50 PM XXCoder: wow new progress bar in apt install?
03:51 PM XXCoder: ohh telemates
03:51 PM XXCoder: I wonder if I can make nc one
03:52 PM XXCoder: one that starts off with "start gcode incation" (g0 g40 g90, g80 etc) as well as start o program #, etc
03:52 PM CaptHindsight: XXCoder: well you know that developers only have so mnay hours in the day so they focus on only the most important things
03:53 PM XXCoder: like turning programs crap
03:53 PM CaptHindsight: new is alwys better :)
03:54 PM Deejay: gn8
04:00 PM CaptHindsight: andypugh: you had given me that link to the top down resin printer
04:00 PM JT-Shop: the only thing funky about geany is if you select all finds it's not obvious how to unselect them
04:01 PM JT-Shop: other than that I'm using it everywhere
04:01 PM CaptHindsight: http://www.catb.org/esr/writings/taoup/html/ch15s02.html
04:54 PM XXCoder: JT-Shop: nice
05:00 PM JT-Shop2: XXCoder: thanks
05:07 PM andypugh: CaptHindsight: That page seems like it might be quite old. I am sure that some people use vi to reply to emails, but I also suspect that most don’t.
05:32 PM Tom_L: JT-Shop2, i think i still have a copy of that ASM book as well
05:32 PM Tom_L: although it's probably covered in dust
05:52 PM SpeedEvil: https://www.youtube.com/watch?v=nBBG-8j15Yc - a great example of 'how many operations deep am I in this part...'
05:52 PM SpeedEvil: Micro Supercharger for The RC Wankel Rotary Engine | Part 1 | The Housing
05:53 PM XXCoder: yeah
05:53 PM XXCoder: so many steps lol
05:55 PM andypugh: Ah, a PocketNC. I seem to be in a minority in really liking that design.
05:56 PM XXCoder: me well kinda in middle
05:56 PM SpeedEvil: It's great - I mean the cutter it can handle is ridiculously tiny, but...
05:56 PM XXCoder: I would like to have it but its pretty limited? dunno
05:56 PM andypugh: (Though why he is tapping with a hammer to zero the A axis rathet than using touch-off I can’t guess.
05:56 PM XXCoder: but then I run big machines
05:56 PM SpeedEvil: andypugh: you really want it to fall off then rather than in machining?
05:57 PM andypugh: PocketNC is a tiny thing for tiny jobs. My point is that I think it is a claver mechanical design.
05:58 PM andypugh: (And runs LinuxCNC…)
05:59 PM andypugh: (Might have been good for my micro-machining project, which I finished today_
06:00 PM SpeedEvil: I just wish mills scaled with maximum weight of work at that size.
06:00 PM SpeedEvil: ^cost
06:01 PM Tom_L: 1/8" shank?
06:07 PM andypugh: I wonder why it is riveted together rather than bolted?
06:10 PM Tom_L: maybe he was a plane riveter in a past life
06:12 PM Tom_L: wonder why he conventional mills most of it
06:13 PM andypugh: Let’s just take a step back… It’s incredible that this project can be undertaken with hobby level tooling.
06:14 PM Tom_L: makes me want a slightly larger version of it for sure
06:14 PM jthornton: what are we making?
06:15 PM Tom_L: turbos
06:15 PM jthornton: nice
06:15 PM Tom_L: for a hobby wankel engine
06:15 PM jthornton: for a rc plane?
06:15 PM Tom_L: rc something
06:16 PM Tom_L: no sound here
06:16 PM jthornton: maybe an rc tank, they used to use rotary engines
06:16 PM Tom_L: i was pleased mine did as well on steel as it did
06:16 PM Tom_L: i was kinda hesitant
06:16 PM jthornton: your mill?
06:16 PM SpeedEvil: https://www.pocketnc.com/blog/2019/2/19/announcing-the-pocket-nc-v2-50-for-pre-orders
06:17 PM XXCoder: andypugh: wonder if it can be made with normal mill lol
06:18 PM SpeedEvil: XXCoder: just scale up tenfold and do 1000hp not 1.
06:18 PM SpeedEvil: that gearbox looks a bit dodgy
06:18 PM andypugh: jthornton: I think tanks used radials, not rotaries
06:19 PM XXCoder: nah its perfect size for small projects
06:19 PM jthornton: that's what I meant lol
06:20 PM andypugh: I used my smallest boring bar yesterday: https://photos.app.goo.gl/PZNTurFniXHF9W1V9
06:22 PM andypugh: (That’s a 2mm hole, (0r 5/64” if you prefer)
06:22 PM SpeedEvil: ;0
06:23 PM andypugh: If you lok carefully you can see that the stock isn’t a single piece, it is 6 pie segments clamped together.
06:24 PM andypugh: (and I have a split collet inside an ER32 collet to hold it, as it is shorter than an ER32 collet)
06:24 PM jdh: did you split something, or make 6 that matched?
06:24 PM andypugh: I made 6 that matched
06:24 PM andypugh: (remarkably well, it appears)
06:25 PM jthornton: are the segments free?
06:25 PM andypugh: The magic of the harmonic drive rotary axis.
06:25 PM andypugh: Yes, 6 completely separate pieces
06:26 PM XXCoder: dang thats small
06:26 PM andypugh: (They have to be, to assemble them around the expander)
06:26 PM jthornton: how did you get them spaced evenly?
06:26 PM andypugh: It’s been a game,,aking something I can’t really see :-)
06:26 PM jthornton: oh I'm looking at the middle part not the part your machining, now I see the lines
06:28 PM jthornton: soon you will be making roots blowers for mini V12 engines
06:28 PM jthornton: or a mini merlin engine
06:30 PM jthornton: one last try at Lubuntu 18 in the morning, I have the rt preempt kernel installed
06:34 PM SpeedEvil: jthornton: Merlin as in spitfire or falcon 9?
06:36 PM andypugh: A friend is making a 1/4 scale Ferrai F1 engine. He uses cameras and large LCD screens to see what is going on.
06:36 PM jthornton: spitfire and mustang and the landcaster I think
06:39 PM andypugh: This is one of his videos, https://www.youtube.com/watch?v=b6CfzNqDR7M
06:39 PM SpeedEvil: I wish his tiny injectors were available
06:39 PM andypugh: The microscopes are a real hel[
06:39 PM andypugh: (help)
06:41 PM Tom_L: true that
06:41 PM Tom_L: some things just wouldn't get done here without one
06:43 PM Tom_L: andypugh he's been at that quite a while. how's he coming with it?
06:43 PM andypugh: I am not sure, his web-page died.
06:43 PM andypugh: He is certainly still at it. But currently seems to be distracted by desigining his ideal lathe for the job....
07:37 PM Tom_L: andypugh if i were to make a mold of multiple of that part, i wonder if one vent to the top connected at the bottom would suffice
07:37 PM Tom_L: say 4 to 6 parts
07:38 PM Tom_L: or maybe a vent between pairs of parts
07:38 PM andypugh: Tom_L: I suspect not, as once there is metal in one part, air can’t get out the others.
07:39 PM Tom_L: might be better just to make multiples of the original in one part and pour each one separate
07:40 PM Tom_L: if it were injected it might be a different case but it's just gravity pour
07:40 PM Tom_L: dunno much about mold design
07:41 PM Tom_L: gonna test the one first to see how it does
09:13 PM skunkworks: https://www.youtube.com/watch?v=euLUDlwlWGc
09:15 PM Tom_L: still playing with spindle power...
09:15 PM Tom_L: no sound but looks pretty cool

09:26 PM XXCoder: now thats hefy link heh
09:26 PM XXCoder: it costs almost as much to ship it. ow
09:27 PM norias: where did you see the shipping cost?
09:27 PM XXCoder: right below price. 1474 bucks basically
09:27 PM norias: oh
09:27 PM norias: hah. yeah, i see it now
09:27 PM norias: Still seems like a good deal
09:27 PM norias: from my quick glance, that looks about the same size as a Tormach 1100
09:28 PM XXCoder: maybe? though I saw one that uses car engine blocks
09:28 PM XXCoder: those blocks can be quite hefy
09:28 PM norias: eh.
09:28 PM XXCoder: http://www.amsequipmentsales.com/Rottler_f68A.html
09:29 PM XXCoder: no wrong link
09:29 PM norias: lol
09:29 PM XXCoder: LOLLL https://www.instructables.com/id/20-CNC-Machine/
09:30 PM norias: hah
09:30 PM XXCoder: cant find it
09:30 PM XXCoder: he bought car engines scrap cast iron
09:30 PM XXCoder: he then used it to make cnc machine
09:32 PM norias: doesn't sound like what i'm after
09:32 PM norias: i basically want to get a frame and put all my parts on it
09:32 PM skunkworks: Tom_L: getting there.
09:33 PM norias: if it works out, try to sell them
09:48 PM norias: hmm
09:48 PM norias: rong fu sells their cnc machines as frame only, if you want
09:49 PM norias: that could be interesting
09:49 PM XXCoder: theres also apparently people who sell extruded cast iron beams
09:49 PM XXCoder: if has cnc machine can use that to make frame heh
09:50 PM Tom_L: yeah, Lcvette bought a cnc with no control i believe
10:04 PM norias: i don't mind their linear rails
10:04 PM norias: or ball screws
10:05 PM norias: but i want to do my own spindle, motors and controller
10:06 PM XXCoder: ie build your own?
10:06 PM XXCoder: make own spindle eyc
10:06 PM XXCoder: etc
10:07 PM norias: uh, yeah, i'll probably grind the spindle myself
10:07 PM norias: at least the first one
10:08 PM norias: buy motors to my spec
10:08 PM norias: i'll probably get pcb's made for the controller
10:08 PM norias: not getting castings done myself saves a ton of time and money
10:08 PM Tom_L: STMBL? looks promising
10:09 PM norias: ?
10:09 PM Tom_L: controller
10:09 PM norias: ahh
10:09 PM norias: haven't gotten that far, yet
10:09 PM norias: wanted to solve the castings problem, first
10:10 PM norias: I need an experimental platform, to start with
10:10 PM norias: and i think these castings will fit the bill
10:10 PM norias: because if i come up with something good, i can just order more
10:11 PM norias: this is an Andy Pugh thing?
10:11 PM Tom_L: he has some but someone else designed it, i forget who
10:12 PM norias: ahh, ok
10:12 PM Tom_L: it's going thru a re'design due to EOL on a chip they used
10:13 PM norias: makes sense
10:13 PM norias: defintely looks interesting, and i'll keep it in mind
10:14 PM norias: i don't know how i feel about using it for the spindle
10:14 PM Tom_L: skunkworks is using it in his demo above
10:15 PM Tom_L: https://www.youtube.com/watch?v=euLUDlwlWGc
10:15 PM skunkworks: I have not blown one up yet.. That says a lot ;)
10:15 PM Tom_L: skunkworks, post your first one on that so he can see
10:17 PM norias: what kind of spindle motor are you using?
10:19 PM norias: i also want to challenge the notion that casting them state-side is cost prohibitive
10:19 PM norias: *sigh*
10:19 PM norias: but the would require me doing the machine design for the frame
10:20 PM norias: which is what i basically get for free buying from china
10:43 PM tubes4branes: hi
10:44 PM tubes4branes: I have an old Bridgeport 3 axis CNC, its circa 2006, with Komollogren servo drives, which can be controlled various ways, and it uses resolver feedback to the servo drives, any idea how difficult it would be to get the machine working with LinuxCNC?
10:47 PM tubes4branes: this is the servo drive it uses:
10:47 PM tubes4branes: https://www.kollmorgen.com/sites/default/files/public_downloads/OFDL%20flyer2006.pdf
10:47 PM tubes4branes: https://www.kollmorgen.cn/sites/default/files/public_downloads/OFDL_INSTALLATION_MANUAL_0.2.pdf
10:48 PM tubes4branes: There is a daisy chain system that uses RS485 or RS232, with addressing per controller, but it looks like the design would not be performant using this method for multi axis contour control, as it doesn't have the frequency response necessary.
10:49 PM tubes4branes: the original controller looks like it used +/- 10V analog signal to control the drive, and closed the feedback control loop independently of the servo drive.
10:49 PM Tom_L: may need to ask at another time too, not sure who is awake atm
10:49 PM Tom_L: or at least check later as well
10:50 PM tubes4branes: An option I looked into will take a pulse / direction input, and then it can simulate an encoder output, and then it can be commanded to a certain position.
10:50 PM tubes4branes: thank you Tom_L
10:50 PM tubes4branes: :)
10:50 PM Tom_L: my friend had a boss5 but used the regular control
10:51 PM Wolf__: might work to break the control down to per,axis direct control of the servo drives with a mesa setup
10:52 PM Wolf__: but dont ask me how to do this lol
10:52 PM tubes4branes: MESA? I usually think of MESA as a OpenGL software emulation.
10:52 PM tubes4branes: I have a robotics background, so I am thinking of it from that perspective...
10:52 PM Wolf__: www.mesaus.com
10:53 PM tubes4branes: what I find odd is that the servo drive company has the ability to have control and coupling over the various communications to the servo drives, but when I crunch the numbers for real time control, I think it falls short.
10:55 PM tubes4branes: if the servo drive is in a PID control loop, and its emulating either quadrature or pulse + direction inputs for control, then it would basically look like a stepper motor to the outside world.
10:55 PM tubes4branes: the +/-10V analog control input would seem undesirable to use though.
10:56 PM tubes4branes: I see, mesa makes the control board interfaces.
10:57 PM tubes4branes: I think I can handle the creation of that part, even spool up my own custom FPGA based PCIe card with DMA for very tightly coupled control and write the necessary drives that would interface with RTL linux that LinuxCNC uses.
10:58 PM Wolf__: thats outside my skill sets lol
10:59 PM tubes4branes: What I'm thinking about is more architectural, if these drives were designed to daisy chain, wouldn't they have some mechanism in place that supports coupled control motion between the X,Y, & Z axises?
10:59 PM tubes4branes: a servo drive for industrial automation from 2006 should have the necessary features built into the design for coupled multi axis control.
11:00 PM Wolf__: you would think, but not really, probably still running on PLC logic as well
11:00 PM tubes4branes: the resolvers support fantastic commutation on the motor, and provide for a resolution of 65535 counts per revolution of the motor.
11:01 PM tubes4branes: they have a 40Mhz processor running on them, and some of them even have a FPGA integrated on them.
11:01 PM tubes4branes: and it supports closed loop feed back control for integral PID controllers.
11:03 PM tubes4branes: as a servo drive they seem adequate vs. replacing the drives, however a motion planner/controller that controls the axises with precision is what I'm hoping to use LinuxCNC for.
11:05 PM tubes4branes: I combed through the servostar programming manuals, that support VarCom, etc, and there is a lot of stuff in there, but it would seem that despite the drives supporting addressing, that their scheme was to slow to implement proper control.
11:06 PM tubes4branes: though then that got me thinking, that you can do feed forward control, and precalculate everything, because any moment in past and future time would know velocity and position, so despite the low baud rate between the controllers 115k baud that you could motion plan to achieve the desired trajectory.
11:07 PM tubes4branes: just some food for thought.
11:07 PM tubes4branes: how are you guys tonight?
11:24 PM _unreal_: There DONE finally
11:25 PM XXCoder: ?
11:25 PM _unreal_: just finished soldering all of the parts onto my 3rd motor controller
11:26 PM _unreal_: tomorrow after work. I'll have to figure out "if i have and where" what chips I have on hand
11:26 PM _unreal_: I need an inverter IC for a TTL signal
11:26 PM _unreal_: so I have 2 choices as I understand it. use 2n222's OR find an inverter IC
11:38 PM pink_vampire: hi
11:42 PM XXCoder: yo
11:51 PM pink_vampire: hi XXCoder
11:52 PM XXCoder: my ac is setup in my room now. yay!
11:52 PM XXCoder: less humid and cooler room for sleeping
11:53 PM pink_vampire: here it was more then 100F
11:53 PM XXCoder: im using ac more as dehumidifer than cooling
11:53 PM XXCoder: i set it to 80f
11:53 PM XXCoder: 75f now actually
11:56 PM pink_vampire: the ac is so noisy i need to use the HF spindle more, so I don't hear it as much
