12:00 AM pcw_home: Then the velocity mode PID would have FF0 =1.0
12:02 AM pcw_home: (FF0 would be 0 in the orient mode PID)
12:02 AM Tom_L: right
12:02 AM Tom_L: that's how it's currently set
12:02 AM pcw_home: if you think about what FF0 does, FF of 1 (and PID=0) is open loop spindle speed control
12:02 AM pcw_home: FF0 of 1
12:02 AM pcw_home: so the PID output = PID command (RPM)
12:08 AM Tom_L: i'll pick this up again tomorrow
12:08 AM Tom_L: thanks
01:27 AM IchGucksLive: hi
01:27 AM IchGucksLive: Tom_L: still on
01:27 AM XXCoder: hey
01:27 AM IchGucksLive: XXCoder: nice storm around texas
01:27 AM XXCoder: it may destroy millions of houses
01:29 AM IchGucksLive: cnn the fake news tcv anounces 130mph and the reporter 10miles of the center is seeing in no wind at all
01:29 AM XXCoder: cnn the fake news?
01:34 AM IchGucksLive: http://www.kiiitv.com/weather/hurricane/tracking-harvey-latest-hurricane-update/467287526
01:34 AM IchGucksLive: live
01:35 AM IchGucksLive: now down Cat3
01:35 AM XXCoder: 3 is still quite bad
01:36 AM IchGucksLive: bad news is DT is suporting the hardliner sherrif
01:43 AM IchGucksLive: http://www.kristv.com/category/292861/live-stream
01:45 AM IchGucksLive: http://edition.cnn.com/2017/08/26/us/hurricane-harvey-landfall/index.html 4hr back
01:46 AM IchGucksLive: im off 2 garden later
02:14 AM Deejay: moin
04:50 AM IchGucksLive: hi
04:50 AM IchGucksLive: peepsalot: winds hedding your way
04:51 AM IchGucksLive: Tom_L: are you here
04:51 AM XXCoder: hey
04:52 AM IchGucksLive: ;-)
04:52 AM IchGucksLive: you never sleep
04:53 AM XXCoder: I do sleep :P
04:54 AM IchGucksLive: can you tell tom if he joins that i got some sort of solution
04:54 AM IchGucksLive: net velocity-mode motion.spindle-on => pid.0.enable or2.x.in0
04:55 AM IchGucksLive: net orient-mode motion.spindle-orient => orient.0.enable pid.1.enable mux2.0.sel or2.x.in1
04:55 AM IchGucksLive: net spindle-pwm-enable or2.x.out hm2_[HOSTMOT2](BOARD).0.pwmgen.00.enable hm2_[HOSTMOT2](BOARD).0.gpio.039.out
04:55 AM IchGucksLive: he shoudt look in the logs
04:57 AM IchGucksLive: its getting hot today so i will do a MTB cource ride till it is to bad
04:57 AM IchGucksLive: bye
04:57 AM XXCoder: later
05:23 AM jthornton: morning
05:23 AM XXCoder: hey
05:23 AM XXCoder: check this video out lolo
05:24 AM XXCoder: https://www.youtube.com/watch?v=ffrq6cUoE5A this is fairly old superbowl ad of much older deaf joke.
05:40 AM XXCoder: jthornton: what ya think heh
05:41 AM jthornton: lol
05:43 AM XXCoder: the deaf joke is in very least over 50 years old
05:43 AM XXCoder: I'd not be surpised if it was closer to 80
05:49 AM jthornton: I want to make a sunrise sunset light for the chickens with an arduino
05:49 AM XXCoder: thats decent idea
05:50 AM jthornton: slowly start giving them some down time at night, right now it's lights on 24 hours a day
05:50 AM XXCoder: you could use solar as light sensor
05:51 AM XXCoder: as well as store up daylight for power
05:51 AM jthornton: I'm going to start with 1 hour of dark and increase it each night
05:54 AM XXCoder: trying to avoid shock or what?
05:55 AM jthornton: dunno just trying to make it natural so they get the idea when to head to the coop and get on the roost and when to come out
05:55 AM XXCoder: nice
05:57 AM jthornton: https://www.amazon.com/Programmable-Light-Dimmer-1110V-Controller/dp/B071X19VL1/ref=sr_1_1?ie=UTF8&qid=1503743184&sr=8-1&keywords=light+dimmer+arduino
05:58 AM XXCoder: 2 left
05:58 AM archivist: another 1000 eft in boxes
05:58 AM archivist: left
05:59 AM XXCoder: just 1,000 wow better order soon
05:59 AM archivist: trying to stop you from continuing a search and buy!
05:59 AM MarcelineVQ: it occured to me that other day that a simply tiny servo flipping a light switch, like an SG90, was a lot less work than attaching mains into a circuit
06:00 AM archivist: that is harder than a plain relay
06:01 AM MarcelineVQ: it's harder to be catastrophically wrong with a 5v servo :o chickens re flammable
06:02 AM XXCoder: non-flammable chickens would be... interesting
06:02 AM XXCoder: can we even cook those heh
06:04 AM enleth: XXCoder: you reminded me of a very silly blind joke
06:04 AM enleth: XXCoder: a blind man walks into a bar
06:04 AM enleth: then into a table, and then into a chair
06:05 AM XXCoder: :p
06:05 AM XXCoder: okay heres other old joke, olviously based on other jokes
06:06 AM XXCoder: theres 4 guys on train, a russian guy, a cuban guy, an american, and deaf american
06:06 AM XXCoder: I forgot one part but shouldnt really matter so here it goes
06:06 AM XXCoder: they was chatting and how common stuff is
06:06 AM XXCoder: russia was drinking expensive volka, and threw it out of window, others asked about it, he said its very common
06:07 AM XXCoder: later, cuban guy threw ciger away, unfinished, its expensive cuban ciger, similiar comment
06:07 AM XXCoder: american guy threw (forgot what) said it is common
06:08 AM XXCoder: deaf guy threw the hearing american out of window, said in american, hearing americans is very common
06:08 AM XXCoder: *america
06:09 AM enleth: that one works best phrased as "nah, we've got plenty of that where I live"
06:09 AM XXCoder: yeah think that is how it goes.
06:10 AM XXCoder: too bad cant remember what american hearing guy is supposed to throw away.
06:10 AM enleth: AFAIR it was a bunch of $100 bills
06:10 AM XXCoder: interesting.
06:11 AM XXCoder: now this is more deaf-specific joke, and yes, very old...
06:12 AM XXCoder: theres few racers, theres hearing guy, hard of hearing guy and deaf drivers in their cars
06:12 AM XXCoder: so race is going on, and theres one spot where water stalls engine so driver has to come out and crank car to start it again (told ya joke is ancient)
06:13 AM XXCoder: hearing person is having hard time, while hard of hearing guy stalls by him
06:13 AM XXCoder: HOH guy had hard time also but managed to start it as deaf guy drives by and stalls there
06:14 AM XXCoder: deaf guy easily starts car and drives away while hearing guy is still stuck there trying to start car
06:14 AM XXCoder: figured out why?
06:16 AM XXCoder: enleth: any guesses? heh
06:16 AM enleth: nope
06:17 AM malcom2073: Sounds like they got pretty shitty cars :P
06:17 AM malcom2073: Or are bad drivers hehe
06:17 AM XXCoder: lol
06:17 AM XXCoder: well deaf guy uses ASL a lot, hard of hearing uses it less, and hearing not at all
06:17 AM XXCoder: so deaf guy got stronger arms to crank start car
06:18 AM Deejay: what is ASL?
06:18 AM XXCoder: american sign language
06:18 AM Deejay: ah
06:18 AM Deejay: haha
06:18 AM XXCoder: ie: using arms and hands to talk lol
06:18 AM XXCoder: that joke is easily 100 years old
06:19 AM Deejay: :)
06:20 AM XXCoder: theres motorcycle joke, but it doesnt work nearly as well
06:20 AM XXCoder: I cant remember most of that either so whatever
06:21 AM XXCoder: btw the cars joke above has visual compoment while saying the joke, with expessions and all but irc cant be done lol
06:21 AM XXCoder: I doubt younger deaf generations know the joke, its too out of date, I'm barely old enough as is to hear the joke
06:22 AM XXCoder: well "hear" the joke anyway
06:23 AM XXCoder: the old hotel joke doesnt work due to tech we have now, ie: cellular phones
06:24 AM XXCoder: well if its modified so guy forgot his phone maybe
06:37 AM jthornton: http://www.powerswitchtail.com/zerocross-tail
06:37 AM XXCoder: ohhh infinite power
06:37 AM XXCoder: interesting
06:57 AM miss0r: yay! The mold released the epoxy without much trouble. I just have a little wood to grind off. (very little). Now comes the next part. I have to machine the rail supports flat and stick it in the surface grinder
06:58 AM miss0r: no cracking or anything
07:00 AM archivist: might want to let it settle for a while before final grind
07:01 AM XXCoder: nice, miss0r
07:02 AM jthornton: got a photo?
07:02 AM miss0r: uploading as we speak
07:02 AM miss0r: archivist: How long time would you reccomend I wait?
07:03 AM miss0r: photo: straight out of the mold: http://picpaste.com/IMG_20170826_133056-qtVrUopZ.jpg
07:04 AM miss0r: jthornton: ^
07:04 AM XXCoder: expoxy grinte eh
07:04 AM jthornton: what are the rails on the right for?
07:04 AM miss0r: The only stuff that stuck to the mold was the 'chamfer wood' on the outside edges
07:05 AM miss0r: jthornton: One set of rails is for the carrige the other set is for the spindle. The spindle will move in Y
07:05 AM jthornton: ah a lathe?
07:05 AM miss0r: indeed
07:05 AM XXCoder: is it epoxy grante casting?
07:05 AM jthornton: nice
07:06 AM miss0r: XXCoder: Yeah. or atleast my take on it
07:06 AM XXCoder: nice. I assume metal is for later milling and mounting of rails
07:06 AM miss0r: jthornton: it is quite small. on the photo: from left to right it is 340mm and 250mm front to back. and is 100mm high
07:07 AM miss0r: XXCoder:Exactly
07:07 AM XXCoder: nice. I do want to try epoxy casting though not for cnc machibe
07:07 AM archivist: miss0r, I suppose it depends on the fully cured time
07:08 AM archivist: depends on which epoxy
07:08 AM miss0r: archivist: acording to the epoxy manufacture it takes 5-7 hours for it to be completely cured. So I'll wait till tomorrow evening to do the milling. and then the final grind some time next week
07:08 AM miss0r: XXCoder: What are you planning?
07:08 AM XXCoder: statues maybe
07:08 AM sync_: you can chuck it in the oven overnight to get better mechanical properties
07:09 AM XXCoder: though casting is very long term plan
07:09 AM miss0r: sync_: Please elaborate
07:09 AM miss0r: XXCoder: And exopy is somewhat expensive imo
07:09 AM XXCoder: indeed
07:10 AM sync_: elevated temperature during curing will increase the strength of the epoxy
07:11 AM miss0r: sync_: How elevated? :] This thing cured itself at above 130degrees C (What my thermal camera is limited at)
07:11 AM miss0r: I think that'll be something i'd be doing for the beta model. This one is still alpha :]
07:13 AM miss0r: in my basement I still had one of thoes white IKEA melanin kitchen wood plate from when we redid the kitchen. and it was still equipped with its blueish protective plastic coating. that worked like a charm. No mold release or anything used. just that plate with said plastic
07:14 AM miss0r: also, it left a quite nice surface (althou hard to tell from the photo)
07:15 AM miss0r: http://picpaste.com/IMG_20170824_150955-mRLH3m2h.jpg
07:16 AM XXCoder: probably same properity that makes sure food dont stick to it.
07:19 AM jthornton: wow talk about firmly attached rails
07:19 AM miss0r: Not exactly. That plastic is just for protecting the melanin plate while you install it in the kitchen. Then you peel it off
07:19 AM XXCoder: yeah its not moving anytime soon.
07:19 AM XXCoder: oh
07:20 AM miss0r: I had all the kitchen put together, and all the blue plastic was still in place. Then one of my wife friends walk in and looks staggered saying: 'I would have never thought you guys would want a blue kitchen'... hehe
07:20 AM XXCoder: lol
07:20 AM XXCoder: cold colors - not good for kitchen
07:20 AM XXCoder: well off to bed, I go. laters
07:21 AM miss0r: see you
07:28 AM miss0r: I am thinking hard about if I should make the spindle bearing house from EG as well. Just molding in some steel for the bearing seats...
07:29 AM * miss0r goes back to the drawing board
07:35 AM Tom_L: JT-Shop, it works.
07:40 AM gregcnc_ is now known as gregcnc
07:40 AM miss0r: gregcnc_: I had success in the epoxy casting yesterday
07:40 AM miss0r: This is what it looks like now: http://picpaste.com/IMG_20170826_133056-qtVrUopZ.jpg
07:43 AM sync_: look into the datasheet of your resin system miss0r
07:43 AM sync_: 60°C for 8h is common
07:43 AM miss0r: When talking about using an oven?
07:44 AM sync_: yes
07:45 AM miss0r: hmm... That is something I will do with the next one. Althou I do believe and hope that what I have done here will be sufficient
07:45 AM miss0r: I don't think this cast is going anywhere in a hurry
07:47 AM sync_: you should also add anchors at odd angles
07:48 AM miss0r: That makes sense. But what theres no pictures of, is that I put in some rebar, and welded everything together with that inside the mold
07:50 AM sync_: then you have to worry about the different temperature coefficients unless you matched the tempco of your casting to the steel
07:50 AM sync_: not in the short run, but in the long run
07:51 AM miss0r: I did nothing like that :] I am just hoping for the best here
09:30 AM Tom_L: BeachBumPete
09:30 AM Tom_L: what's up?
09:41 AM Tom_L: quiet in here today
09:48 AM phipli: Perhaps some of them are hiding from the storm in Texas
09:48 AM Tom_L: i doubt it
09:49 AM Tom_L: they usually stand outside and watch it until it's right on them
09:49 AM Tom_L: youtube will attest to that
10:03 AM IchGucksLive: hi
10:03 AM Tom_L: it works now
10:03 AM IchGucksLive: Tom_L: did you get the info
10:04 AM IchGucksLive: nice
10:04 AM IchGucksLive: Tom_L: will you make a info page on that
10:04 AM Tom_L: there is one that i followed
10:05 AM IchGucksLive: and ofcause what has been ow the big problem that solved itfialy
10:05 AM Tom_L: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?SpindleOrient
10:05 AM Tom_L: that goes along with the vismach sample
10:06 AM Tom_L: i forgot the pwmgen.00.enable on the pid.1 side
10:06 AM IchGucksLive: did you get my code i woudt have mailed it if i coudt find your mail at the pages
10:06 AM Tom_L: added an or2 and fixed it
10:06 AM IchGucksLive: as i said
10:06 AM Tom_L: no i didn't see it
10:07 AM BeachBumPete: Tom_L morning
10:07 AM IchGucksLive: net velocity-mode motion.spindle-on => pid.0.enable or2.in0
10:07 AM IchGucksLive: net orient-mode motion.spindle-orient => orient.0.enable pid.1.enable mux2.0.sel or2.in1
10:07 AM IchGucksLive: net spindle-pwm-enable or2.out hm2_[HOSTMOT2](BOARD).0.pwmgen.00.enable hm2_[HOSTMOT2](BOARD).0.gpio.039.out
10:07 AM Tom_L: i got rid of 039 out but that's what i did
10:08 AM IchGucksLive: ok finaly it works
10:08 AM Tom_L: still need to tune the pid
10:08 AM Tom_L: takes too long to get up to speed
10:08 AM IchGucksLive: on the wiki there shoudt be a HAL and ii to get more detail
10:09 AM IchGucksLive: as more and more like to get TC
10:09 AM Tom_L: look at the vismach toolchanger code
10:09 AM IchGucksLive: and the simple ones getting cheeper and cheeper
10:09 AM IchGucksLive: ok im off BIG BBQ here in town
10:10 AM Tom_L: have fun
10:14 AM Tom_L: https://github.com/LinuxCNC/linuxcnc/blob/master/configs/sim/axis/vismach/VMC_toolchange/toolchange.ngc
10:14 AM phipli: https://www.youtube.com/watch?v=ImVK5cGVrpQ#t=06m10s
10:14 AM Tom_L: BeachBumPete that should follow what yours needs pretty close
10:16 AM BeachBumPete: Ok thank you I will try to understand it
10:16 AM Tom_L: and i did get orient working both fwd and rev
10:16 AM Tom_L: the pid is off a bit but it works
10:16 AM MarcelineVQ: phipli: haha
10:20 AM Tom_L: BeachBumPete, i've just accomplished the first line :)
10:21 AM phipli: MarcelineVQ: I've considered making similar things for emergencies :)
10:22 AM Tom_L: why are your plugs go godawful big?
10:22 AM Tom_L: so*
10:23 AM phipli: Tom_L: is that aimed at me? That video is from the continent - mine are even worse
10:24 AM phipli: Safe... but irritating
10:24 AM Tom_L: hah
10:24 AM phipli: Ours are generally fused in the plug
10:24 AM Tom_L: some of ours are
10:24 AM phipli: but we do get proper electricity
10:25 AM phipli: (240c)
10:25 AM Tom_L: still smaller though
10:25 AM phipli: *v
10:25 AM phipli: (missed the key)
10:29 AM BeachBumPete: that must be nice actually here we gotta wire for 240 v everywhere we want it but the washer/dryer and stove LOL
10:30 AM Tom_L: i bet you know it if you get ahold of it too
10:33 AM Tom_L: what opens a .dot file in linux?
10:34 AM MarcelineVQ: graphviz probably
10:34 AM MarcelineVQ: depends what a dot file is :>
10:34 AM Tom_L: i think it's just an intermediate file in this case
10:35 AM phipli: BeachBumPete: we have special wiring for some cookers and showers to give even more
10:35 AM phipli: 15Amp 240v or even more for some showers
10:36 AM phipli: back home we used the cooker socket for the welder...
10:36 AM Tom_L: what size breakers are for a normal circuit?
10:36 AM phipli: 13A
10:36 AM phipli: oh wait
10:36 AM phipli: sorry
10:36 AM phipli: 13A is for a socket
10:36 AM phipli: you remember I said fuses in plugs?
10:36 AM phipli: 13A is the biggest "normal"
10:36 AM Tom_L: screw in fuses?
10:36 AM Tom_L: oh
10:36 AM Tom_L: nevermind
10:37 AM BeachBumPete: showers?
10:37 AM phipli: https://www.stevensonplumbing.co.uk/images/source/Electrical/BS1362_fuses/BS1362_13_Amp_Plugtop_Fuse.JPG
10:37 AM Tom_L: BeachBumPete yeah they do weird things over there :)
10:37 AM phipli: BeachBumPete: indoor rain?
10:37 AM BeachBumPete: I know what a shower is but what do they need 240v power for?
10:38 AM Tom_L: on demand heaters
10:38 AM BeachBumPete: ah ok
10:38 AM Tom_L: oh and they heat their towels
10:38 AM Tom_L: i never understood that
10:38 AM BeachBumPete: THAT I understand
10:39 AM Tom_L: because of the humidity?
10:39 AM BeachBumPete: no its just nice to get out of a warm shower and have a nice warm towel to wrap up in LOL
10:40 AM phipli: the shower breaker in this house is rated to 40A 240v
10:40 AM HighInBC: that is a hot shower
10:40 AM phipli: Tom_L: we don't all heat our towels :p
10:41 AM HighInBC: real men shower with 5000W
10:41 AM BeachBumPete: I think our hot water heater is at like 30 amps
10:41 AM phipli: BeachBumPete: that is the reason for heating them though yes. That and to help dry them
10:41 AM Tom_L: i figured since it rains so much there you did it for the humidity
10:42 AM BeachBumPete: Its not humid in my Master Bedroom suite ;)
10:42 AM Tom_L: when i get this pid working better, i'll post a video
10:43 AM Tom_L: right now i'm just sitting on my arse
10:43 AM BeachBumPete: Some of the condos we redo have wall mounted towel warmers installed
10:43 AM BeachBumPete: they work quite well
10:43 AM phipli: We have a combi boiler as well
10:43 AM BeachBumPete: altho I do not have any idea what power consumption is
10:43 AM phipli: that is gas though
10:43 AM BeachBumPete: I THINK they are run off typical wall current tho
10:44 AM phipli: towel heaters are weird
10:44 AM phipli: they run off electric even in houses with central heating
10:44 AM phipli: assumption is I guess that you spend more time naked / drying towels than you do with the heating on
10:44 AM phipli: (*naked in the bathroom)
10:45 AM BeachBumPete: they also have a lot of those new fancy multi head showers
10:45 AM Tom_L: BeachBumPete when you get a chance i'd like to look over your config files
10:46 AM BeachBumPete: quite a few have in floor tile heaters in the bathrooms as well
10:46 AM Tom_L: those are probably more common
10:46 AM BeachBumPete: Tom_L I need to get the current ones out of the machine
10:46 AM Tom_L: i figured that
10:46 AM BeachBumPete: the ones I have here on the PC are early ones I think
10:46 AM Tom_L: i just want what you're currently running
10:47 AM BeachBumPete: not even quite sure HOW to get them out of the machine tho. I have a USB stick in there
10:47 AM BeachBumPete: can you just open the file and copy and paste?
10:47 AM Tom_L: yes
10:47 AM BeachBumPete: ok great
10:47 AM Tom_L: do you know what directory they're in?
10:47 AM BeachBumPete: I have to run a custom part sometime this weekend
10:48 AM BeachBumPete: you mean the .ini and the HAL right
10:48 AM Tom_L: yes
10:48 AM Tom_L: and if there's any extra .hal files
10:48 AM Tom_L: like for pendant etc
10:49 AM BeachBumPete: there was a file that Connor created that had the information for the toolchanger inputs and outputs and where they go In think
10:49 AM Tom_L: good
10:49 AM BeachBumPete: You're in Texas right? Hows the weather ;)
10:49 AM Tom_L: no, Ks
10:49 AM BeachBumPete: ah thats right
10:49 AM Tom_L: and it's great
10:49 AM BeachBumPete: LOL
10:50 AM BeachBumPete: I am working on this rather large impressive beachfront restaurant at work right now
10:50 AM BeachBumPete: lots of nice woodwork in there
10:50 AM BeachBumPete: I probably should be working there today but I just did not want to
10:51 AM Tom_L: all work and no play...
10:51 AM BeachBumPete: I know right
10:51 AM BeachBumPete: I have been TRYING to design this new rail in F360
10:52 AM BeachBumPete: I got the rail drawn and extruded
10:52 AM Tom_L: yeah, how's your F360 experience going?
10:52 AM BeachBumPete: but then I tried to move stuff around and run into lots of problems
10:52 AM BeachBumPete: mostly with selecting stuff
10:52 AM BeachBumPete: somtimes things will refuse to be selected
10:53 AM Tom_L: of newer software, i've only used solidworks and catia
10:53 AM BeachBumPete: I have a bank of windows in the part that I need to lower down a bit and despite MANY efforts to do so I cannot move them now LOL
10:53 AM Tom_L: that should be a couple clicks and done deal
10:53 AM BeachBumPete: IKR
10:53 AM BeachBumPete: I right click
10:54 AM BeachBumPete: the orbital menu pops up
10:54 AM BeachBumPete: I click move
10:54 AM BeachBumPete: then I do a window selection around the entire bank of windows
10:54 AM Tom_L: i should download it sometime and look it over
10:54 AM Tom_L: it's not like i don't already have enough projects
10:54 AM BeachBumPete: when I try to enact a point to point move it lets me select the points and then nothing happens
10:55 AM BeachBumPete: finally gave up on it last night
10:55 AM Tom_L: is it a 3d model or an assembly?
10:55 AM BeachBumPete: its a single 3d model part
10:56 AM Tom_L: i wonder how similar it is to acad
10:57 AM BeachBumPete: typically I draw this stuff in 2d CAD and then just machine it as needed but I thought since F360 has built in CAM I might be able to do some neat stuff with it but so far I am not having much luck
10:57 AM Tom_L: my kid just took a class on the current acad
10:57 AM Tom_L: it was required or he likely wouldn't have taken it
10:59 AM Tom_L: incidentally, i loaded the student ver here and looked at it a bit
11:00 AM Tom_L: but that's about it
11:00 AM BeachBumPete: I understand.
11:00 AM BeachBumPete: several people in here seemed to be using it so I started to work with it I thought one of them was you but was apparently mistaken
11:00 AM Tom_L: i could probably pull it into catia and fix it fairly easy
11:00 AM BeachBumPete: heh probably
11:01 AM Tom_L: andy's the only one i know using it to any degree
11:01 AM BeachBumPete: I can just take the sketch and hopefully turn it into a .dxf and export it to my 2d cad
11:01 AM Tom_L: i'm sure there are others
11:01 AM BeachBumPete: then work with it the way I typically do
11:01 AM Tom_L: depend if you want to learn or just get it done
11:02 AM BeachBumPete: well its funny you put it that way
11:02 AM BeachBumPete: I got paid for this part already
11:02 AM BeachBumPete: not that there is any real deadline or anything
11:02 AM BeachBumPete: but my eldest daughter in TN had a wreck and needed some help paying for a deductible
11:02 AM BeachBumPete: so I paypal'd her some of the money LOL
11:02 AM BeachBumPete: it will be done regardless
11:03 AM BeachBumPete: but it kind of puts a point on it now hehehe
11:03 AM Tom_L: so do both. get the part done but do it in F360 too
11:03 AM BeachBumPete: well that was the plan hehehe
11:03 AM Tom_L: i did that with solidworks and catia
11:04 AM mtpocketscncm: does anyone have a link for huanyang vfd control on linuxcnc. i foumd it once before but now i cant find it. should have book marked
11:04 AM BeachBumPete: I was hoping to be able to start the program, draw the part, use the onboard CAM and the linuxCNC post and cut it out seamlessly
11:04 AM Tom_L: i probably did 75-100 more problems than were required to pass the class
11:04 AM BeachBumPete: but I suppose that was kinda optimistic
11:04 AM Tom_L: mtpocketscnc it's not in the wiki is it?
11:05 AM BeachBumPete: opening up F360 now
11:05 AM Tom_L: BeachBumPete how long does their licence last?
11:05 AM BeachBumPete: honestly don't let me make you think I am not happy with the program tho
11:05 AM Tom_L: or do you have to keep renewing it?
11:05 AM BeachBumPete: it is quite good so far
11:05 AM BeachBumPete: my lack of understanding of it should not be a criticism of the program itself
11:05 AM mtpocketscncm: thats where i thought. ill go look again
11:06 AM Tom_L: BeachBumPete there's always a learning curve
11:06 AM BeachBumPete: for sure
11:07 AM Tom_L: i almost gave up on orient :)
11:07 AM BeachBumPete: I kinda labor under the false impression that at some point in my life all of my past experiences with other struggles will culminate in an ability to trudge thru almost anything sucessfully
11:18 AM Tom_L: seems there are other complaints about their sketch tool
11:18 AM BeachBumPete: oh yeah
11:19 AM Tom_L: how often do you have to renew the license?
11:19 AM BeachBumPete: not sure
11:19 AM BeachBumPete: apparently it is free for startups I guess yearly?
11:19 AM Tom_L: k
11:20 AM Roguish: BeachBumPete: hey what's free???
11:20 AM BeachBumPete: f360
11:20 AM Tom_L: air
11:20 AM Roguish: yes.. have it. works ok.
11:21 AM BeachBumPete: I would say it works a bit better than OK it is quite good but my lack of understanding of it is my only issue
11:21 AM Tom_L: from what i've seen here it sounds a bit clunky still
11:21 AM Roguish: it's evolving.
11:22 AM BeachBumPete: well I am not sure it is clunky or that I am not doing it right I suppose it could be a glitch hard to say really
11:22 AM Tom_L: i suppose if i needed a cam i'd take a look at it but for now i think i'll pass
11:22 AM Roguish: clunky, but FREE. that makes up for a lot
11:22 AM BeachBumPete: the timeline feature is quite nice
11:22 AM BeachBumPete: I don't need a CAD or CAM either but having a seamless package sounded real nice
11:23 AM Tom_L: catia's cam sucks the big one
11:23 AM Tom_L: i'll tell you that for sure
11:23 AM Tom_L: and it takes a 3rd party software to change the post
12:08 PM TurBoss: http://www.openplcproject.com/plcopen-editor
12:09 PM Tom_L: is that for ladder?
12:09 PM TurBoss: y
12:10 PM TurBoss: sems cool
12:10 PM Tom_L: i haven't gotten into ladder yet
12:25 PM JT-Shop: f360 you have to renew after 30 days then after that in 12 months
12:48 PM Castro: Hi
01:07 PM enleth: g
01:07 PM enleth: damn
01:20 PM Tom_L: JT-Shop, any advise on tuning a position pid ?
01:21 PM Tom_L: i can't get enough output from the pid to get the motor to turn at a reasonable rate unless i pump the values way up
01:21 PM Tom_L: then it chatters and pops the fuse
01:22 PM Tom_L: like it's overshooting and trying to correct...
01:22 PM sync_: Tom_L: are you trying to connect a position pid directly to a motor?
01:23 PM Tom_L: yes
01:23 PM Tom_L: 1:1 belt but yes
01:23 PM sync_: that's not going to work very well
01:23 PM Tom_L: how else would you orient a spindle?
01:24 PM sync_: cascade it with a velocity and accel pid
01:24 PM sync_: or just velocity
01:24 PM Tom_L: you're asking alot :) i don't know that much about pid
01:25 PM Tom_L: just enough to get the spindle working at the right speed
01:25 PM Tom_L: and it's probably not tuned the way it should be
01:27 PM pcw_home: Isn't the spindle drive a velocity mode drive? (spindle speed proportional to voltage)
01:30 PM pcw_home: Does linuxCNCs spindle orient commanded position limit acceleration or does it just output the orientation angle immediately?
01:30 PM pcw_home: If so you may need to feed it through the limit component
01:38 PM Tom_L: pcw_home, yes
01:39 PM Tom_L: spindle is velocity normally
01:39 PM Tom_L: i set an output limit on the pid
01:39 PM Tom_L: maybe that's not where to do it
01:40 PM Tom_L: i can't tell if orient limits acceleration or not
01:40 PM Tom_L: doesn't appear to however it doesn't come up to speed like the velocity pid loop
01:41 PM Tom_L: i may switch to a velocity pid for it and add a near component
01:41 PM Tom_L: see what that does to it
01:50 PM JT-Shop: Tom_L: no clue sorry, all I know about tuning velocity PID I got from Peter
01:50 PM Tom_L: i'm not used to the extra terms FF0 1 & 2
01:51 PM Tom_L: this one is sure alot more sluggish than the normal velocity pid
01:52 PM Tom_L: anyway, i did actually accomplish what i set out to do... get orient working
01:52 PM Tom_L: i'll try to get the spindle working better but i don't have a tool changer anyway
01:52 PM JT-Shop: what did you have to do?
01:53 PM Tom_L: oh i did notice one thing, it gets confused on the first try between 0 & 180 degrees
01:53 PM Tom_L: JT-Shop, this was just an exercise
01:54 PM Tom_L: also it just sits there on the first M19 command if no other spindle commands have been executed yet
01:54 PM JT-Shop: so you have to do a M3,4 or 5 first
01:55 PM JT-Shop: ?
01:58 PM Tom_L: it seems so
01:58 PM Tom_L: i'll fiddle with that a bit more to see for sure
02:00 PM Tom_L: the output was taking too long so i ran pid.1.output thru scale and found that was a bad idea
02:01 PM Tom_L: JT-Shop, i need one of your little breakers.... going thru too many fuses here :)
02:05 PM malcom2073: Heh, usually after the third or fourth fuse, I swap out for a breaker :P
02:06 PM Tom_L: yeah that's about right..
02:13 PM * Loetmichel just had to mount a bit of XPS on the garage door to prevent wifey from getting any MORE scratches to her brandnew car. Thanks mercedes for the extra work. (Trunk door opens motorized, but doesent check if there is room to open...) -> http://www.cyrom.org/palbum/main.php?g2_itemId=16791&g2_imageViewsIndex=1
02:15 PM sync_: Tom_L: daisychain the position to a velocity pid and then tune the velocity and then the position loop, position should be a simple p controller
02:16 PM Tom_L: so add a 3rd pid compnent?
02:16 PM Tom_L: component*
02:18 PM sync_: more like a second, depending on what you already have
02:19 PM Tom_L: well i have 2 but they're switched with a mux2 because orient doesn't use the normal motion.spindle-xxx
02:20 PM Tom_L: i could set up a 3rd and match it to the normal pid for M3 M4 control and run the positonal one thru it
02:21 PM Tom_L: pid.1.out => pid.2.command ?
02:22 PM Tom_L: or hardcode pid.2.command to a S value and let pid.1. control it's position?
02:23 PM Tom_L: i don't think that would work...
02:23 PM Tom_L: anyway, gotta run an erand
02:46 PM JT-Shop: Tom_L: what amp rating
02:52 PM Tom_L: i've been using 3-4
02:53 PM Tom_L: i saw the 5 & 2A ones
02:53 PM Tom_L: not sure which to pick
02:53 PM Tom_L: 5 would probably be ok
02:55 PM Tom_L: i could put a meter on it later to see what it normally draws under load
03:30 PM teo_: sudo /etc/init.d/gdm3 stop command not found on debian wheezy why ?
03:31 PM TurBoss: sudo systemctl restart lightdm/gdm3/xmm
03:31 PM TurBoss: *xdm
03:33 PM teo_: i want install my graphics card nvidia and now its tell to run the sudo apt-get install nvidia-xconfig but first i want run sudo /etc/init.d/gdm3 stop and this is not work can you help me ?
03:34 PM TurBoss: propietary nvidia driver doesn't work with realtime kernels
03:34 PM TurBoss: or thats what i know
03:34 PM TurBoss: someone correct me if I'm wrong
03:35 PM teo_: what is mean this ?
03:37 PM teo_: how i know if i i have real time kernel ?
03:37 PM TurBoss: linuxCNC only works with realtime kernels
03:38 PM TurBoss: only simulator can be run without
03:38 PM TurBoss: you should use the noveau drivers
03:38 PM TurBoss: the opensource ones
03:40 PM BeachBumPete: Man I know everyone has him losing but I would LOVE to see Conor McGregor smash Floyd Mayweather tonight. Anyone else hoping for the biggest upset EVER!!! LOL ;)
03:41 PM TurBoss: no
03:41 PM TurBoss: :)
03:41 PM TurBoss: joking
03:41 PM TurBoss: no interest here...
03:41 PM BeachBumPete: I would love to hear all the nay sayers shut up
03:50 PM malcom2073: Wouldn't you *not* hear them then?
03:50 PM BeachBumPete: yeah the silence would be deafening.....and BEAUTIFUL ;)
03:52 PM Tom_L: there's a fight tonight?
03:52 PM Tom_L: :)
03:52 PM BeachBumPete: well yeah apparently
03:52 PM Tom_L: somebody's makin bank on that
03:53 PM BeachBumPete: was going to try to go to hooters or someplace showing it but the wife wants to stay home and cook shrimp enchilada's and chill. So unless I ante up the hundred clams for the PPV I will have to just read the results in the morning.
03:53 PM BeachBumPete: they both will make crazy stupid money win or lose
03:54 PM Tom_L: no fight's worth a ben franklin to me
03:54 PM BeachBumPete: me neither
03:54 PM BeachBumPete: which is why we usually go out to dinner somewhere that is showing it ;)
03:54 PM BeachBumPete: some places have cover fees for it tho
03:54 PM Tom_L: that is unless i was selling cable
03:55 PM BeachBumPete: I think its a bit stupid really. if they made it say 40 bucks think how many more households MIGHT actually pay for it.
03:56 PM BeachBumPete: I would probably pay 30 or 40 for it and I am NOT a Mayweather fan LOL
04:19 PM teo_: i run sudo nvidia-xconfig and my system not boot on graphics how can i fix this ?
04:20 PM teo_: I only have access to the command line
04:26 PM Deejay: gn8
05:24 PM Crom: ah... it's my hard drive going bad... there goes $80
05:24 PM Tom_L: catch it before you lose everything
05:44 PM Kevin`: do you have backups? you should have backups
05:58 PM JT-Shop: sorta late to be asking about backups...
06:55 PM teo_: someone know how can i install BCM4318 BROADCOM wifi card to my laptop ?
07:02 PM Kevin`: teo_: open laptop, attach card to pci slot, attach antennas, close laptop..?
07:02 PM teo_: i mean driver
07:02 PM teo_: not hardware
07:04 PM Kevin`: https://wiki.debian.org/bcm43xx
07:08 PM Tom_L: teo_, how long are you gonna fight that install?
07:13 PM teo_: 1 week 10 hours a day
09:23 PM Tom_L: ok BeachBumPete
09:24 PM Tom_L: i've got it working to a point that motion.orient-is-oriented goes true and motion.spindle-locked goes true
09:25 PM Tom_L: this little thing will never orient right because it's a cheap motor etc but the mechanics of it are in place and working
09:26 PM Tom_L: so with the motion.spindle-locked ouput you can feed that to your tool changer code
09:26 PM Tom_L: which has a very good example in that vismach directory i gave you
09:36 PM BeachBumPete: Tom_L sorry my friend I was out in the shop working on something
09:36 PM BeachBumPete: I appreciate your efforts to make this work.
09:37 PM BeachBumPete: I am running some parts this weekend. I need to find a stopping point so I can convert the spindle drive BACK to analog control
09:41 PM Tom_L: did you have it working with analog?
09:41 PM XXCoder: nice so far https://www.youtube.com/watch?v=c2ExwOAjLNw
09:41 PM Tom_L: and is the analog +-10v or just 0 to +10
09:42 PM BeachBumPete: yeah it was analog
09:42 PM Tom_L: i should take a video of it but i just came back inside and i'm gonna have some ice cream now
09:42 PM BeachBumPete: I think it is 0-10v and then a direction command or soemthing?
09:42 PM Tom_L: could be
09:42 PM BeachBumPete: hehe Ice cream supercedes
09:43 PM Tom_L: i figured i was at a point i can stop
09:43 PM Tom_L: the pid isn't ever gonna work right on this spindle since it's not a servo
09:43 PM Tom_L: just a cheapo dc motor
09:44 PM BeachBumPete: well I tried AGAIN today to work with that model in F360
09:44 PM BeachBumPete: finally gave up and exported the original sketch into my old cad
09:44 PM Tom_L: hah
09:44 PM BeachBumPete: every time I tried to make changes something else in the model would become corrupted
09:45 PM Tom_L: i'd like to see if catia could do it but i don't want your proprietary files
09:45 PM Tom_L: make the changes and give it back...
09:45 PM XXCoder: and sell files!
09:45 PM BeachBumPete: proprietary files?
09:45 PM Tom_L: pfft i'm not into guns
09:45 PM Tom_L: you're sellin em aren't ya?
09:46 PM BeachBumPete: I'm not really into guns either but I love air targe rifles. ;)
09:46 PM BeachBumPete: sure
09:47 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/screenshots/sherline.hal
09:47 PM Tom_L: that's what the current hal looks like
09:47 PM Tom_L: i need to clean up a few things but it's working
09:48 PM Tom_L: oh the next step is to remap the M6 command
09:48 PM Tom_L: then you will be able to call that file i linked earlier
09:49 PM BeachBumPete: I thought Andy's setup was not using remap?
09:50 PM Tom_L: i dunno
09:50 PM Tom_L: what i saw looked pretty straightforward though
09:50 PM Tom_L: i haven't tried his carousel comp
09:53 PM XXCoder: techinically, primitive tech channel finally entered iron age lol
11:43 PM Vitran: Saw this and thought if something like it was possible for metal https://www.youtube.com/watch?v=MhsOeTr2kh4
