01:51 AM Deejay: moin
04:59 AM Tom_L: morning
05:48 AM * Loetmichel now looks like edward from twighight... had to mill some aluminium brackets out of 2,5mm sheet alu... noticed that only 3mm alu is in stock... so i faced a 250mm by 330mm piece down to 2,5mm. with a 6mm mill bit... in "hand programming" the CNC router. *MAN* what a glittery mess!!!!111
06:05 AM SpeedEvil: https://boards.greenhouse.io/spacex/jobs/4405408002?gh_jid=4405408002 Fun job.
06:20 AM jthornton: morning
06:20 AM XXCoder: yo
08:36 AM _unreal_: well I was supposed to go to work today
08:36 AM _unreal_: still no school
08:36 AM _unreal_: so no day care FUCK ME
08:39 AM FinboySlick: Send the kids to work.
08:39 AM FinboySlick: Put some hair on their chest.
08:45 AM roycroft: if babysitting is the worst you suffer from the hurricane you're a very lucky person
09:22 AM _unreal_: milling more parts for my daughters cnc
09:23 AM * _unreal_ REALLY needs 1/8th up cut bits
09:23 AM _unreal_: all I have are straight and down
09:57 AM _unreal_: damn I dont know how that got past me making a part and I didnt put holding tabs on it
09:58 AM _unreal_: well its done part never slipped good enough
10:58 AM rene-dev: pcw_home pcw_mesa do you have 7i76e + 7i74 firmware?
11:15 AM _unreal_: 10min of milling left finally
11:16 AM Loetmichel: _unreal_: i left the 3dprinter running and was going home an hour ago ;)
11:17 AM Loetmichel: ... just logged into the remote control website: it says still 1 hour to go ;)
11:18 AM _unreal_: I was supposed to be at work :( no daycare today doe to the hurricane
11:18 AM Loetmichel: i LIIIKE that setup
11:18 AM _unreal_: arg...
11:18 AM _unreal_: 3d printer is one thing I dont have
11:18 AM Loetmichel: i think i will refit my CNC mill with a webcam and install a webserver on its PC as well
11:19 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=17424&g2_imageViewsIndex=1 <- really funny to look at the printer(s) from home
11:19 AM _unreal_: Loetmichel, I'm milling a 3d part right now
11:19 AM _unreal_: when its done. i have to mill a pocket reciver and flip the part over
11:20 AM Loetmichel: _unreal: i think it would be very convenient to have a web-actiavated power strip on the CNC router and a webcam
11:21 AM Loetmichel: so you can watch it finish a long job and then shut it down remotely
11:21 AM _unreal_: yep
11:21 AM _unreal_: finally a min to go
11:21 AM Loetmichel: the number of times i sat at the company 2-3 hours after hours just to have the router finish a job...
11:22 AM _unreal_: ya some parts it would be great to just be able to go fast :(
11:24 AM gregcnc: some serious linuxcnc 5 axis work going on https://youtu.be/78thHwCuW-E
11:40 AM FinboySlick: Loetmichel: 240v relay? If you're only shutting it off while it's not cutting you don't need that big a relay.
11:47 AM roycroft: used, managed power strips can be had on ebay fairly cheaply
11:48 AM Loetmichel: FinboySlick: could do that, but as i have a shopvac that provides the vacuum for the table, sometimes a second one for swarf collecting and the CNC machine itself i would prefer to be able to individually swiitch them on and off, regardless if the PC is still running
11:49 AM FinboySlick: roycroft: wrt the web cam, I think it's good to be able to see what's going on.
11:49 AM FinboySlick: Loetmichel: Fair... Though I still fail to see a use case where you'd need them on when the PC is off.
11:51 AM ziper: _unreal_, i could print you stuff
11:52 AM _unreal_: oh shit... I just relized I fucked up the size on this part
11:52 AM _unreal_: was supposed to be 5/8 not 1/2"
11:52 AM Loetmichel: FinboySlick: for example when the sheet metal sticks over the vacuum table big time
11:53 AM Loetmichel: and it would fall down and damage the mill bit otherwise
11:53 AM _unreal_: I guess I can corect it on the other side
11:53 AM _unreal_: so I can salvage it
11:53 AM _unreal_: ish
11:53 AM Loetmichel: hint: my vacuum table is 600*400mm, my usual aluminium sheets come in 1000*400mm
11:53 AM Loetmichel: so they stick out one side or the other QUITE a bit
11:54 AM _unreal_: oh Loetmichel let me link to you an image
11:54 AM FinboySlick: Loetmichel: OK, and that would require the vacuum to be on when the PC is off?
11:54 AM _unreal_: https://drive.google.com/open?id=1LFl4v5AcZk8ed-yGZLsisnEbMLLkKv7Q
11:54 AM _unreal_: made this a few days ago have not tested it yet but..
11:55 AM Loetmichel: FinboySlick: until i can go there and take it off: yes
11:55 AM Loetmichel: wouldnt make sense for a weekend, but for a lunch break it would be useful
11:55 AM Loetmichel: just an example though
11:55 AM FinboySlick: But does the PC need to be off during lunchtime?
11:56 AM Loetmichel: the other way around would be more useful, to be able to deactivate the shopvacs while on lunch but let the PC running
11:56 AM _unreal_: Loetmichel, what cha think?
11:57 AM Loetmichel: looks like it could work. unless you try to mill thru the part inside the "gasket" area
11:57 AM _unreal_: heh
11:57 AM _unreal_: ya
11:57 AM _unreal_: its tiny 2x2"
11:57 AM _unreal_: the vac plate that is
11:57 AM FinboySlick: Loetmichel: Well, that's sort of what I was saying. Let the PC drive the relays, there aren't any realistic use cases where you want the PC off and the other things on.
11:57 AM Loetmichel: i have reasons to make it with holes in a sacrificial plate and have the air channels underneath
11:58 AM Loetmichel: because i mostly do sheet metal and i DO mill thru
11:59 AM Loetmichel: FinboySlick: other than a web controlled power strip being easier AND cheaper than trying to get a third LPT port in the PC and control some relais with that, also make a box with outlets for that that "VDE" compliant and so on
12:00 PM Loetmichel: _unreal_: my vac plate:
12:00 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=14682&g2_imageViewsIndex=1
12:00 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=14685
12:01 PM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=17171&g2_imageViewsIndex=1 <- facing off new sacrificial plate
12:01 PM Loetmichel: https://www.youtube.com/watch?v=ZwAizto843U <- drilling said new plate... ;)
12:03 PM Loetmichel: ... takes a while to drill 20k 3mm holes... and then another 20k with a 0,8mm drill trhu the plate
12:03 PM Loetmichel: 3mm wide and 80% of the plate deep
12:03 PM Loetmichel: then 0.8mm and thru
12:03 PM Loetmichel: so any "milled open" holes dont lose that much air
12:04 PM Loetmichel: but it still has a decent "gripping surface"
12:04 PM Loetmichel: also those holes fit broken 1/8" mill bit shafts so i can use them as locating pins ;)
12:06 PM _unreal_: What material is that gray plate?
12:06 PM _unreal_: oh thats that resin stuff right?
12:07 PM roycroft: https://www.ebay.com/itm/333232668243
12:07 PM roycroft: there
12:07 PM roycroft: is one with a web interface
12:07 PM roycroft: new-fangled thing
12:08 PM _unreal_: 1pm guess I'm going to make lunch and mow the lawn
12:10 PM Loetmichel: gray= PVC 20mm, brown: "pertinax"
12:11 PM Loetmichel: no idea what thats called in english
12:11 PM Loetmichel: resin filled paper and then pressed
12:23 PM gonzo_: paxolin ?
12:27 PM Loetmichel: gonzo_: Phenolic it is
12:39 PM gloops: im making a mould for a sign that im going to cast in grp resin
12:39 PM PL7icnc: hi is the forum down for maintainance
12:39 PM PL7icnc: im getting 404 on
12:40 PM PL7icnc: https://forum.linuxcnc.org
12:41 PM PL7icnc: pcw_home, online Sir
12:42 PM PL7icnc: pcw_mesa, Are you on Peter
12:42 PM PL7icnc: up as CA isearly
12:43 PM PL7icnc: Mr gloops what a Heck on the 31oktober
12:44 PM PL7icnc: is somone online or am i posting to myself
12:44 PM gregcnc: ...
12:44 PM PL7icnc: thanks
12:45 PM gregcnc: if you start answering your own questions
12:45 PM PL7icnc: then i need to go to bed
12:45 PM gregcnc: no problem with the forum
12:45 PM PL7icnc: Mr gregcnc is the forum also down on your side
12:46 PM PL7icnc: so Europe feels the Huricane force shaking the antenna
12:46 PM gloops: hi, 31 october - halloween
12:46 PM gregcnc: i have no idea where the server is
12:47 PM PL7icnc: mr gloops seams so Boris is going as Europa
12:47 PM PL7icnc: Mr gregcnc thanks on inf i can ping liuxcnc but not forum
12:48 PM _unreal_: there lawn is mowed and lunch is in the toster oven
12:48 PM _unreal_: toaster
12:48 PM PL7icnc: MrBusiness3, gloops today the 5-Axis moved on all joints the first time from the past Developer builder if been told
12:49 PM gloops: https://www.etsy.com/uk/listing/620887162/georgian-victorian-style-english-house?ref=shop_home_active_42
12:49 PM PL7icnc: Mr gloops, today the 5-Axis moved on all joints the first time from the past Developer builder if been told
12:49 PM PL7icnc: mr gloops is it yours
12:49 PM gloops: excellent PL7icnc 5 axis must be a challenge
12:50 PM gloops: no im making a model to cut on cnc, then take a mold - going to copy iy
12:50 PM PL7icnc: i need to get there but i got no Contract this year
12:50 PM PL7icnc: im on a 3meter by 2meter by 1meter mold cnc
12:51 PM PL7icnc: made out of wood and aluminium
12:51 PM PL7icnc: as you see in the YT
12:53 PM PL7icnc: im off only wanted to post the 5axis is running comment
01:03 PM gloops: so, cut the basic model from wood
01:03 PM gloops: then hours of filling sanding waxing to get a mirror finish - then lay up the fibreglass mold
01:11 PM gloops: the bit im not sure about is the metal powder filler
01:12 PM gloops: too expensive to fill the whole sign with that, so an application of metal powder in clear gel coat to a depth of .5mm maybe, then fill with normal resin
01:29 PM fragalot: hey
01:31 PM fragalot: quiet here lately
01:32 PM Tom_L: well it was.
01:32 PM fragalot: Tom_L: what did you do?
01:32 PM Tom_L: i did nothing
01:32 PM fragalot: Exactly
01:32 PM Tom_L: it's your turn
01:32 PM fragalot: you just stood there and watched didn't you
01:33 PM fragalot: Freak out.
01:33 PM fragalot: Le freak. C'est chic.
01:33 PM fragalot: *drumline*
01:34 PM miss0r2: 'ello
01:35 PM fragalot: miss0r2: https://photos.app.goo.gl/7echiLscTjzMqSck9 <- don't mind the shitty glueline on the display
01:35 PM miss0r2: nice.. what is that funky finish/colour?
01:35 PM fragalot: box came like that
01:35 PM miss0r2: ha... :)
01:36 PM miss0r2: I just ordered three boxes of 10x 500ml brake cleaner spray at ~14eur a box :)
01:37 PM fragalot: I buy that stuff at 99ct a can
01:37 PM fragalot: https://photos.app.goo.gl/WB92mhD98xPhuqCh8
01:37 PM miss0r2: meh... This is cheap my local standards.. ridiculously cheap :D
01:37 PM fragalot: don't mind the crappy looking TIG braze joint
01:38 PM miss0r2: theres alot of 'don't mind' there, ha? :D
01:38 PM fragalot: oh yeah, this is a hackjob.
01:38 PM miss0r2: :D
01:38 PM miss0r2: it still looks nice. So, what amount of backlash do you get with the gears on the encoder?
01:39 PM fragalot: tons.
01:39 PM fragalot: I want to replace that with a T2.5 belt eventually
01:39 PM miss0r2: so you have to step over the threads by alot? :)
01:39 PM fragalot: those gears are just "ones I had" that came with the lathe
01:39 PM miss0r2: okay.. it is a hackjob then :D
01:39 PM miss0r2: But if it works, it works
01:39 PM fragalot: indeed
01:40 PM fragalot: what I find interesting though, is that I can make it take .2mm/rev feed cuts at 2mm deep, and it does it fine
01:40 PM miss0r2: I realy wouldn't mind having that myself.. So I guess you could potentially add a stepper to the x-axis as well to have it automatically cut threads
01:40 PM fragalot: but if I *DARE* to touch the handwheel, the motor stalls
01:40 PM miss0r2: and basically have it completely cnc
01:40 PM fragalot: (and then jumps up to 3k RPM to catch up)
01:40 PM miss0r2: hehe
01:40 PM fragalot: if I wanted that, i'd have bought this as a commercial package
01:40 PM miss0r2: it is a siemens, after all :
01:40 PM fragalot: no, not the siemens
01:41 PM fragalot: the hybrid servo running the leadscrew
01:41 PM miss0r2: hah...
01:41 PM fragalot: :D
01:41 PM miss0r2: Looks realy interresting
01:41 PM fragalot: it could do with some gearing I think, but I need a higher res encoder to do that really
01:41 PM miss0r2: So basically you set a depth, press go and it runs the tool forward at a given pitch?
01:42 PM fragalot: yeah, it's literally just an electronic gearbox
01:42 PM fragalot: nothing more
01:42 PM fragalot: currently i've got it so it gives me a range of 0.02mm to 5.0mm per rev
01:42 PM * miss0r2 is just trying to figure out the procedure - to see if it makes sense for him
01:42 PM fragalot: any higher than that, and I need to send multiple pulses in too fast succession to the stepper drive and it freaks out
01:42 PM fragalot: (eg. 2 pulses, followed by some down time)
01:43 PM miss0r2: hmm.. unless you run the spindle realy slow?
01:43 PM miss0r2: ohh.. it doesn't have the res
01:43 PM fragalot: no, regardless of spindle speed, it's just how fixed point integer math works
01:43 PM miss0r2: never mind
01:43 PM fragalot: yeah
01:43 PM fragalot: timing belt on the spindle would resolve that. cheaper than a proper encoder
01:43 PM miss0r2: stuff I'd like to add, if I got an electronic leadscrew: REALY HIGH PITCH :) like 100mm/rev
01:44 PM miss0r2: for grinding out lube channels in the internal surfaces of gears/bushings
01:44 PM fragalot: can easily be done, just need a 48k encoder
01:44 PM miss0r2: yeah
01:44 PM fragalot: :P
01:44 PM miss0r2: or I just need to make a custom gearbox to add to my lathe
01:44 PM fragalot: well, this is a 600 atm, which gives me 2400 counts/rev in quadrature
01:45 PM Tom_L: you should fill that weld joint.... it's horendous :D
01:45 PM fragalot: Tom_L: not a weld though so there! :D
01:45 PM fragalot: figured i'd try my hand at tig brazing.
01:45 PM fragalot: turns out I should have done that on scrap pieces first
01:45 PM fragalot: :D
01:45 PM Tom_L: never tried that
01:45 PM miss0r2: is the the part where I go 'don't quit your day job'? ;:D
01:46 PM fragalot: miss0r2: yes sir. I'll continue to play with the NTX1000 then
01:46 PM miss0r2: damn you ! :D
01:46 PM * miss0r2 shakes his fist at fragalot
01:46 PM miss0r2: I enjoy tig brazing myself...
01:46 PM miss0r2: Although, I never realy got a handle on doing it with a torch
01:46 PM Tom_L: only brazing i did was with a torch
01:47 PM fragalot: don't worry, it is only a dual spindle 65mm bore with C1, C2, B1, Y1, and Y2 axis with 12k and 10k rpm live tools
01:47 PM miss0r2: fragalot: If for whatever reason you are not aware of it by now, I am quite envious of you having access to that :D
01:48 PM fragalot: exclusive access*
01:48 PM miss0r2: ... not helping :D
01:48 PM fragalot: :D
01:48 PM miss0r2: meh... anything it can do I con do - with a file... only slower... and of less quality and repeatability :-|
01:48 PM Tom_L: needs a pickoff attachment
01:49 PM fragalot: Tom_L: oh it has a part grabber
01:49 PM fragalot: not a pesky little bin, an actual arm that goes to grab the part so it doesn't get dinged up
01:50 PM fragalot: and a barfeeder, and 70bar coolant pump, but that goes without saying of course
01:50 PM Tom_L: i suppose it hands it to you too
01:50 PM fragalot: Tom_L: on a freaking tray.
01:50 PM fragalot: (it doesn't, but it will after a year or so)
01:50 PM miss0r2: bah.. thats it for tonight... my oldest son had a deamon inhabiting his body from 01:00 to 04:30 last night... so I need some rest now :D
01:51 PM fragalot: miss0r2: gnite :)
01:51 PM miss0r2: fragalot: Enjoy life without children !
01:51 PM miss0r2: cya
01:51 PM miss0r2: (while it lasts anyway)...
01:51 PM miss0r2: now:
01:51 PM * miss0r2 is out
01:51 PM Tom_L: mine are growed up
01:51 PM Tom_L: mostly
01:52 PM Tom_L: running machines that make me envious
01:52 PM fragalot: :P
01:52 PM Tom_L: i think one has a 65' bed
01:53 PM fragalot: what taper does it cut from one end to the other? :P
01:53 PM Tom_L: zimmerman
01:54 PM pink_vampire: did someone here build the MPCNC?
01:54 PM CaptHindsight: some kids never grow up
01:54 PM * Tom_L might fall into that category
01:54 PM fragalot: :P
01:55 PM CaptHindsight: which is fine, just that why would people want someone like that in charge of anything?
01:55 PM CaptHindsight: familiarity
01:57 PM CaptHindsight: get sleep is my only unsolicited advice for soon to be parents
01:58 PM CaptHindsight: might be your last chance for 20+ years
01:58 PM fragalot: that is when they buy a house that you have to renovate
01:59 PM CaptHindsight: mine will not ask me to help with any of that again, I have one of their cars apart for 2 years
02:00 PM fragalot: lol
02:00 PM CaptHindsight: frame up restoration
02:01 PM CaptHindsight: started out as a paint job only
02:01 PM Tom_L: you kept finding rust and didn't know when to stop?
02:01 PM CaptHindsight: parts are cheap
02:02 PM CaptHindsight: new suspension, rims, tires, carpet, headliner, seats, body panels....
02:03 PM CaptHindsight: don't ask for me to do it the right way
02:03 PM fragalot: project binky? :P
02:04 PM CaptHindsight: finishing this month
02:04 PM Tom_L: so what _is_ this unobtanium materal on the JWST anyway?
02:05 PM CaptHindsight: not sure whats up with the weather here, too perfect
02:06 PM Tom_L: https://www.jwst.nasa.gov/
02:06 PM fragalot: CaptHindsight: there just isn't any bad weather left
02:06 PM CaptHindsight: have a feeling this winter will be really bad this winter to make up for it
02:07 PM fragalot: it'd better be. get rid of those damn import tropical bugs
02:09 PM CaptHindsight: fragalot: did you find a clever way to sleep comfortably?
02:09 PM fragalot: CaptHindsight: the weather's cooled down again
02:09 PM CaptHindsight: good
02:09 PM fragalot: does that count?
02:09 PM fragalot: went from 35+ to 16C
02:09 PM CaptHindsight: nice
02:14 PM CaptHindsight: fragalot: https://imgur.com/zvxoHUT 3840 x 2160 DLP res, ~2 sec/100um printer rate
02:14 PM CaptHindsight: Z
02:15 PM fragalot: Neat.
02:15 PM CaptHindsight: fragalot: who makes wide linear positioners? 300-500mm, 300-1,000mm travels
02:16 PM fragalot: the usual suspects i'd imagine?
02:17 PM CaptHindsight: not the case
02:17 PM fragalot: not even igus?
02:19 PM fragalot: nvm, their W series only goes to 195x228 carriages
02:21 PM CaptHindsight: what's that brand out of Italy?
02:22 PM fragalot: no idea
02:25 PM CaptHindsight: built my own anyway
02:25 PM CaptHindsight: I need some voice coil linear servos
02:26 PM CaptHindsight: few mm travel, ~100g force, but really fast
02:26 PM fragalot: so.. subwoofers? :P
02:26 PM fragalot: combined with a class A analog feedback circuit for fast closed-loop control with perfect pitch.
02:27 PM CaptHindsight: http://moticont.com/voice-coil-motor.htm they want ~$3k for an assembled positioner
02:27 PM CaptHindsight: http://moticont.com/voice-coil-stage.htm
02:28 PM fragalot: Neat.
02:28 PM fragalot: I wonder how they got to 29.95µ resolution.
02:28 PM CaptHindsight: https://www.h2wtech.com/category/voice-coil-stages#productInfo1
02:29 PM fragalot: because that is a very specific number
02:30 PM CaptHindsight: <30um :)
02:30 PM fragalot: I like how they all reference "high speed" yet none specify what that is
02:31 PM jdh: faster than 7
02:31 PM fragalot: surely not a 9 though?
02:33 PM CaptHindsight: https://www.youtube.com/watch?v=hKdkF_f9xWM
02:35 PM fragalot: 7.3 at best.
02:35 PM CaptHindsight: G's
02:35 PM fragalot: a girls' best friend :D
02:37 PM CaptHindsight: *accelerations up to 10 g's are possible under closed loop control
02:37 PM CaptHindsight: *accelerations up to 20 g's are possible under open loop control
02:37 PM fragalot: not bad, i'd sayµ
02:37 PM CaptHindsight: https://www.h2wtech.com/page/linear-motion-calculator#Acceleration2
02:57 PM CaptHindsight: https://www.youtube.com/watch?v=uZRL879p5HM
02:58 PM CaptHindsight: https://www.youtube.com/watch?v=WCKpH_tlXAY USB --> some microcontroller
02:59 PM CaptHindsight: how are you supposed to build a working system to ship to customers using all these windows USB tools?
02:59 PM fragalot: because windows now supports running linux tools natively
02:59 PM fragalot: that said, i've had my fair share of grievances with how microsoft deals with USB devices
02:59 PM CaptHindsight: great I can run the dev software GUI
02:59 PM CaptHindsight: now what?
03:00 PM fragalot: especially if you are the one developing said USB device
03:00 PM fragalot: >.>
03:00 PM CaptHindsight: heh
03:00 PM CaptHindsight: bbl
03:08 PM Deejay: gn8
03:27 PM t4nk-freenode: gnate to you too, Deejay
04:50 PM _unreal_: OK i'M BACK any one miss me?
04:51 PM _unreal_: even a littlejust got back from taking my daughter to the playground
04:51 PM pink_vampire: me
04:51 PM pink_vampire: _unreal_: <3
04:51 PM _unreal_: was going to try and go to acehardware its freaking closed and gone :(
04:51 PM _unreal_: I need some 1/8th up cut bits :/
04:51 PM _unreal_: :)
05:12 PM jthornton: evening
05:15 PM Tom_L: hey
05:15 PM Tom_L: you get lots of rain?
05:16 PM jthornton: in Crossville TN tonight, heading to Horn Lake MS tomorrow
05:16 PM jthornton: no, I left yesterday and stayed in Hickory NC last night
05:16 PM Tom_L: been there a time or two
05:16 PM jthornton: rode 150 miles of the Blue Ridge Parkway today
05:17 PM Tom_L: you on your bikes or car?
05:17 PM Tom_L: that'd be quite a trip on a bike
05:29 PM jthornton: blue screen of death on the laptop lol
05:31 PM Tom_L: sucks
05:31 PM Tom_L: are you driving or biking?
05:49 PM jthornton: in the Honda Insight
05:49 PM jthornton: the following radar is pretty cool
05:50 PM jthornton: as well as the lane control that steers the car for you
05:52 PM _unreal_: ok milling out my retainer pocket so I can do my flip side milling
05:52 PM _unreal_: :/
05:52 PM _unreal_: yay for 3d milling the manual way
05:53 PM Tom_L: jthornton so what, you just sit there and sleep?
05:53 PM Tom_L: we drove a civic the other day with slowdown cruise, lane control etc
05:53 PM Tom_L: well she did anyway
05:54 PM gregcnc: clearly you survived
05:55 PM Tom_L: for now i'm stuck driving an 18 equinox
05:57 PM _unreal_: nothing like a nice Up cuter to really muck up the finish ;)
05:59 PM _unreal_: and there it is
05:59 PM _unreal_: ok time to see if I can finish this flip side 3d mill
06:10 PM _unreal_: cant wait to be done with the 3d milling stuff
06:10 PM _unreal_: soo much setup work
06:15 PM _unreal_: my part is chattering a tiny bit but not enough to cause an issue
06:15 PM _unreal_: regardless i'm pocketing the Nuts in the back side of the part for blind install
06:26 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Skate_truck/Skate_truck3.jpg
06:26 PM Tom_L: i did that on those but don't have a pic of the finished bottom
06:28 PM _unreal_: as in roller skates?
06:28 PM Tom_L: yes
06:29 PM _unreal_: nifty
06:29 PM _unreal_: sigh. just an hour to go
06:29 PM Tom_L: http://tom-itx.no-ip.biz:81/~webpage/cnc/Skate_truck/Skate_Truck1.jpg
06:29 PM _unreal_: I really want to add a pully reduction to this cnc so bad
06:29 PM _unreal_: not for the precision but for the speed
06:29 PM _unreal_: I could run it so much faster
06:30 PM _unreal_: right now I'm doing the 3d job on the back side of the part and milling corrected hole locations
06:31 PM _unreal_: I caught it before I milled it thankfully
06:31 PM _unreal_: not that it would have mattered. it would have been under milled roughed if you will ;)
06:31 PM _unreal_: I had drawn the circle the wrong size.
06:31 PM _unreal_: drew it to the inner ID not the outer ID
06:31 PM _unreal_: of the sleeve it will retain
06:33 PM _unreal_: FINALLY 3d milling I can bump the feed rate
06:41 PM chunkypuffs: anyone here good with marlin?
06:43 PM Tom_L: that could be a #reprap or #robotics question
06:43 PM Tom_L: but #robotics is kinda quiet
06:44 PM _unreal_: chunkypuffs, what are you trying to figure out?
06:44 PM _unreal_: not that I can help
06:44 PM chunkypuffs: I bought a mechanical switch sensor for bed levelling
06:44 PM chunkypuffs: And I was wondering about how to install it, since there's lots of conflicting info
06:44 PM Tom_L: http://marlinfw.org/docs/features/auto_bed_leveling.html
06:45 PM chunkypuffs: That's software, not hardware.
06:45 PM chunkypuffs: I already know how to compile it with that feature enabled.
06:45 PM chunkypuffs: I'm asking about what I should toss and what I shouldn't.
06:45 PM chunkypuffs: The particular conflicting information is that people suggest getting rid of the existing Z stop
06:45 PM chunkypuffs: They suggest ripping that wire out, and replacing it with this, which I don't want to do unless that's actually required.
06:46 PM Tom_L: https://www.youtube.com/watch?v=G-TwWfUzXpc
06:46 PM chunkypuffs: That's not specific enough
06:46 PM chunkypuffs: I'll watch it though.
06:46 PM Tom_L: what do you expect from #linuxcnc? :)
06:46 PM chunkypuffs: He seems a lot more informative, so I'll watch it for the purpose of learning.
06:46 PM chunkypuffs: Tom_L, CNC advice :)
06:47 PM chunkypuffs: Routers aren't the only thing that take numbers in and shit work out.
06:47 PM chunkypuffs: my particular printer is an ender 3
06:47 PM chunkypuffs: And this guy isn't using that, so I don't know if he has extra pins, or what.
06:48 PM Tom_L: i don't think the parts know what they're called
06:48 PM Tom_L: or what printer they got stuck on
06:49 PM _unreal_: heh I think my Z is breaking a sweat doing this 3d mill
06:50 PM chunkypuffs: this vid really does help Tom_L
06:54 PM jthornton: Tom_L, no it buggs you every minute or so to steer lol
07:10 PM _unreal_: ok just got the charcoal grill going and steak thawing
07:11 PM _unreal_: and just and just paused the job to pull the part up again and ensure particals were getting under and lifing the part
07:11 PM _unreal_: I should clamp it down but I dont know where any screws of the right size are right off the top of my head :(
07:44 PM _unreal_: shhhhh
08:33 PM CaptHindsight: friends don't let friends run Marlin
09:08 PM _unreal_: poor bastard
09:34 PM _unreal_: There just found a few more minor errors that I just corrected
09:34 PM _unreal_: These tweaks are really starting to shape my final part
09:38 PM Elmo40: what is wrong with Marlin?
09:39 PM Tom_L: belongs in the ocean
09:39 PM Tom_L: actually marlin is the leading reprap control software i believe
09:39 PM Tom_L: but we just don't support it
09:40 PM Elmo40: ve7it, nice power supply setup. Clean and simple
09:41 PM Elmo40: what do you support?
09:41 PM Tom_L: i'm not support staff here but i use linuxcnc
09:42 PM Tom_L: we have highly unpaid professionals here for that
09:54 PM cradek: Tom_L: hey but you make twice what I do
09:59 PM Elmo40: Marlin is supposed to handle CNC stuff.
09:59 PM Elmo40: so they claim
10:00 PM Elmo40: i havent tried, though. i dont know if they support Mesa hardware.
10:01 PM Elmo40: i am interested in using all my hardware for 3D printing with linuxCNC, though nothing newer than ~8 years old is floating around the net.
10:02 PM Elmo40: the ytube vids i see have guys showing off their system but no links or explanations.
10:25 PM Tom_L: Elmo40, marlin is based on grbl which is a subset of the RS274 standard. far less complete than linuxcnc
10:26 PM Tom_L: it may be able to run a small cnc with a limited gcode set
10:51 PM Tom_L: anyone ever wind springs? have any mandrel to wire diameter spring back data? (i guess that's what you call it)
10:51 PM Tom_L: the plan is to wind a wire around a shaft and be able to calculate the finished spring diameter
10:57 PM Tom_L: for extension springs, not compression
10:57 PM Tom_L: but that part shouldn't matter for the diameter calcs
11:05 PM flyback: i SEEn the machines that do it
11:05 PM flyback: my mind can't handle watching it coil then right angle bend
11:05 PM flyback: cause the way the machine does it
11:05 PM flyback: goes counter to you think you would have to do it manually
11:06 PM Tom_L: i've seen some cool cnc coil winders
11:07 PM flyback: been woking on my data recovery project last year
11:07 PM flyback: been elminating easy hard drives 40 of them
11:07 PM flyback: well the first one I did from the origionlal lost data pile
11:07 PM flyback: took 2 weeks but got a lot of data off it
11:07 PM flyback: I am happy
11:10 PM flyback: Drevain
11:10 PM flyback: Drevain
11:10 PM flyback: 4 months ago
11:10 PM flyback: Living in the south a tranny is something that shifts gears, everywhere else its someone who has had their gears shifted.
