12:06 AM MacGalempsy: https://oklahomacity.craigslist.org/tls/6008339323.html
12:09 AM MacGalempsy: so many harding turret lathes.
12:10 AM MacGalempsy: anyone in here using gmocapy?
12:15 AM XXCoder: my death has been overrated
12:15 AM XXCoder: whats up
12:19 AM XXCoder: finishing up this old tony video, nice
12:46 AM MacGalempsy: not much. they are changing the bit again
12:46 AM XXCoder: cool
12:47 AM MacGalempsy: so just woke from a food coma and chillin in the trailer
12:47 AM MacGalempsy: which lcnc gui are you going to use?
12:47 AM XXCoder: right now "stock"
12:47 AM XXCoder: havent tried any gui
12:48 AM XXCoder: besides stock that is
12:48 AM MacGalempsy: u mean axis?
12:48 AM XXCoder: axis gui view?
12:49 AM MacGalempsy: yeah. basically comes up with the config wizard
12:49 AM XXCoder: option come up on that
12:50 AM XXCoder: something andclassic ladder view
12:50 AM XXCoder: havent tried either
12:50 AM XXCoder: http://linuxcnc.org/docs/html/gui/images/axis.png this is mine looks like, so yeah axis
12:51 AM MacGalempsy: yeah. pretty basic. i use that with a pyvcp sidebar and a few extra tabs for subroutines
01:49 AM XXCoder: yeah need to check out other styles lol
01:49 AM XXCoder: see what I like
01:50 AM XXCoder: lol I was reminded on gandi bug in old civilizions game
02:11 AM SpeedEvil: https://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_20170226233931&SearchText=linuxcnc - vs https://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_20170226234203&SearchText=mach3
02:11 AM SpeedEvil: we need to step up our game! :)
02:13 AM xxcodercnc: man kits has gotten cheaper
02:17 AM Deejay: moin
02:18 AM CaptHindsight: heh, I broke a good 1/4-20 tap and all I had left was a HF version
02:19 AM CaptHindsight: it's so far out of spec that I had to use what was left of the broken tap to get fasteners to actually fit into the threads
02:21 AM CaptHindsight: MacGalempsy: locate the laser/s outside of the build chamber
02:21 AM xxcodercnc: CaptHindsight: ugh ya once bough $5 (hal;f off) of tap set. its trash
02:21 AM CaptHindsight: that is how real SLS printers do it
02:22 AM CaptHindsight: xxcodercnc: good as fishing weights
02:22 AM xxcodercnc: lol
02:22 AM MacGalempsy: CaptHindsight: just shoot straight thru a pane of glass?
02:23 AM CaptHindsight: MacGalempsy: nope, a window that is optically clear at the wavelength of the laser
02:24 AM MacGalempsy: hmmm. ok. i was thinking of replacing the fan was a cpu watercooler
02:25 AM CaptHindsight: http://www.laserresearch.net/shopping/shopdisplayproducts.asp?id=278 for CO2 / 10.65um
02:25 AM xxcodercnc: heh configuring mty machine fot proper parameters then finally doing a basic engrave test
02:25 AM MacGalempsy: ok. so a co2 tube instead of an ir diode laser
02:26 AM SpeedEvil: MacGalempsy: http://thorlabs.de/ has exotic fibre
02:27 AM xxcodercnc: man I love using camera as distance travel checks
02:27 AM xxcodercnc: even wi9th pototocam its super accurarte
02:27 AM MacGalempsy: was wanting to just try plastics, maybe like grount petg
02:29 AM MacGalempsy: thanks for the tips.
02:29 AM CaptHindsight: MacGalempsy: how much power were you planning?
02:30 AM CaptHindsight: what wavelength?
02:30 AM CaptHindsight: you want to heat the plastic powder in the build chamber to just below its melting point
02:30 AM MacGalempsy: 880um or the next one up. was just looking at some 1.6w ttl diode lasers
02:31 AM MacGalempsy: still brainstorming
02:31 AM CaptHindsight: then you can move the laser faster to build quicker
02:32 AM MacGalempsy: now that im working on location it will not be a fast build.
02:34 AM MacGalempsy: does aluminum printing really require 600deg build chamber?
02:35 AM CaptHindsight: that would be difficult
02:35 AM MacGalempsy: i imagine so
02:35 AM CaptHindsight: 600f maybe for high temp thermoplastics
02:35 AM CaptHindsight: 600C would be a challenge
02:35 AM MacGalempsy: abs is like 230c
02:36 AM MacGalempsy: figured that would be a good first attempt
02:37 AM xxcodercnc: just be sure on air safety
02:37 AM CaptHindsight: nitrogen oven
02:37 AM MacGalempsy: xxcodercnc petg is similar sans deadly fumes
02:37 AM CaptHindsight: I don't know what those maker SLS printers do
02:38 AM CaptHindsight: no oven, no nitrogen, no roller spreader
02:38 AM xxcodercnc: petg is dfine yeah
02:38 AM xxcodercnc: njylon is ok I think
02:38 AM xxcodercnc: abs ehh
02:39 AM xxcodercnc: I read about husmand and wife deaf by sls emitting co2
02:39 AM MacGalempsy: would like to think about eventually getting to Aluminum during the build process
02:39 AM xxcodercnc: but according to some people its way too much co2 for sls
02:39 AM xxcodercnc: so dunno
02:39 AM MacGalempsy: heard about that but couldnt find reference to a machine type
02:40 AM CaptHindsight: http://www.sciencemag.org/news/2017/02/cheap-plastic-film-cools-whatever-it-touches-10-c
02:40 AM MacGalempsy: perhaps argon would be safest
02:40 AM Wolf_: work the specs backwards from commercial machines
02:40 AM CaptHindsight: depends on the wavelength
02:41 AM MacGalempsy: the local pottery shop had some aerospace fabric that was pretty cheap
02:41 AM CaptHindsight: argon is not clear at 10.6um
02:41 AM MacGalempsy: used for kilns
02:41 AM CaptHindsight: you get a halo
02:41 AM MacGalempsy: ah. didnt consider the gas
02:41 AM Wolf_: pull a vacuum in the chamber?
02:42 AM CaptHindsight: nitrogen for 10.6um laser
02:42 AM MacGalempsy: saw one 15w laser tube on ebay, but most were 40w
02:43 AM CaptHindsight: 40w CO2 RF lasers are around $5k used
02:44 AM MacGalempsy: :/
02:44 AM CaptHindsight: easily refurbed for ~$1200
02:44 AM CaptHindsight: glass tubes are cheap
02:44 AM CaptHindsight: but are not easily rebuilt
02:45 AM MacGalempsy: thats why diodes came to mind for plastic
02:45 AM MacGalempsy: $160 for 1.6w
02:45 AM MacGalempsy: 920um or something like that
02:46 AM CaptHindsight: http://www.ebay.com/itm/ULR-30-Universal-Laser-Tube-CO2-30W-Wavelength-10-6-m-For-parts-Need-Repair-/201834584613
02:47 AM CaptHindsight: http://www.ebay.com/itm/WORKING-UNIVERSAL-UL-30-30W-CO2-LASER-PROFESSIONALLY-RE-GASSED-RE-FURB-TESTED-/162402614488
02:47 AM SpeedEvil: At that price, get ten working chinese ones
02:48 AM CaptHindsight: what the plan for steering the beam? Galvo or ?
02:48 AM MacGalempsy: lol. maybe after getting success doing plastics, i'll nut up on more expensive stuff
02:50 AM MacGalempsy: no idea not havent even started the design phase. the first thought was to mount the diode assembly straight on the x/y and try to do insitu cooling
02:51 AM MacGalempsy: i use 70c on the bed w petg and warping is minimal
02:51 AM SpeedEvil: MacGalempsy: not particularly hard - a tiny waterflow.
02:52 AM MacGalempsy: thats exactly what came to mind.
02:52 AM MacGalempsy: a little cpu cooler w radiator
02:52 AM MacGalempsy: put one on each nema1u too
02:53 AM MacGalempsy: *17
02:55 AM xxcodercnc: engraving 1000 mm/m and plunge of 400 mm/m. makes sense?
02:55 AM xxcodercnc: wood
02:55 AM xxcodercnc: tool is tiny, 2.5 mm dia
03:06 AM MacGalempsy: ni
03:07 AM MacGalempsy: what is this mm thing? heh
03:07 AM xxcodercnc: my machine is metric.
03:07 AM MacGalempsy: metric? no se
03:07 AM MacGalempsy: :p
03:08 AM MacGalempsy: did you calc your feedrates?
03:09 AM MacGalempsy: might try that with an online calculator to see if you are close
03:09 AM xxcodercnc: not really
03:10 AM MacGalempsy: basically first calculate the rpm then use that to calc the feedrate
03:11 AM xxcodercnc: i decided on 12000 rpm
03:11 AM MacGalempsy: Feed-Rate-Calculator.phtml
03:11 AM MacGalempsy: oops
03:12 AM MacGalempsy: http://www.daycounter.com/Calculators/GCode/Feed-Rate-Calculator.phtml
03:12 AM MacGalempsy: i used this one before, you will need to find some sfm for the wood
03:13 AM * MacGalempsy going back to my book
03:25 AM xxcodercnc: hmm calculation says 60 m/min
03:25 AM xxcodercnc: I guess it means 60,000 mm/m
03:26 AM xxcodercnc: thats way faster than my machine can do.
03:32 AM xxcodercnc: I wish image to gcode have a way to be cancelled
03:32 AM xxcodercnc: because if mistake it takes forever
03:34 AM archivist: just kill it
03:43 AM xxcodercnc: thats what i did yeah
04:12 AM xxcodercnc: so far running fine on dry run
04:30 AM xxcodercnc: last run with tb6560 it drafted. so far good with new electrics
04:38 AM xxcodercnc: finally details. im making world!
04:56 AM xxcodercnc: done. wow nicely detailed
05:21 AM MacGalempsy: good work xxcodercnc
05:23 AM jthornton: morning
05:23 AM xxcodercnc: yeah working on third design already lol just random graphics
05:23 AM xxcodercnc: hey jt
05:28 AM xxcodercnc: MacGalempsy: first was world height map
05:28 AM xxcodercnc: then second was some random swirl thingy
05:28 AM xxcodercnc: now is linux pengin
05:28 AM xxcodercnc: last one for day though
05:29 AM jthornton: you making chips?
05:30 AM xxcodercnc: well kinda
05:30 AM xxcodercnc: im making powder
05:30 AM xxcodercnc: tiny tool, 12k rpm, 1000 mm/m
05:30 AM xxcodercnc: I preduict can go 2,000 mm/m just fine but plunges should be slower
05:31 AM xxcodercnc: calculator says I sould use 60,000 mm/m so yeah
05:32 AM xxcodercnc: i knew it though
05:32 AM jthornton: no wonder the machining world like mm/m it just sounds so fast
05:32 AM xxcodercnc: those ball em is still good for wood, though it was too worn for inocel engraving.
05:33 AM xxcodercnc: heh it seems to me that its same for inches
05:33 AM xxcodercnc: ips for config, gcode uses ipm
05:36 AM xxcodercnc: well whats uyp jthornton
05:39 AM jthornton: testing dewey's per instance homing branch on my mock up gantry
05:39 AM xxcodercnc: wish pic to gcode dont take so long lol
05:39 AM xxcodercnc: pwer instance? I guess seperate spi9ndles? I remember something like that.
05:42 AM jthornton: before with JA you had to home all now you can pick a joint and home it and if it is part of a multi joint axis then all the joints on that axis home.
05:43 AM xxcodercnc: interesting
05:43 AM jthornton: hmm looks like rain for the next few days here
05:44 AM xxcodercnc: here its random rain
05:44 AM xxcodercnc: ever-washing-ton
05:47 AM MacGalempsy: cold rain? it has been chilly here over the last few nights
05:48 AM xxcodercnc: low 40s
05:48 AM xxcodercnc: 50s when sunny
05:48 AM jthornton: been down to the 30's here last couple of days
05:50 AM MacGalempsy: brrrr
05:51 AM xxcodercnc: fancy
05:51 AM xxcodercnc: clear nights we have ice here
06:06 AM xxcodercnc: pengin is pretty olvious even on first shaping pass.
06:09 AM xxcodercnc: finishing pass
06:14 AM xxcodercnc: bamboo looks amazing post-cut
06:14 AM xxcodercnc: i mlove that material.
06:14 AM Deejay: yeah
06:15 AM xxcodercnc: its 25 cent floor sample if you can imange it
06:15 AM xxcodercnc: couldnt find more perfect testing sample than that!
06:20 AM xxcodercnc: done. can finally pull part off
06:20 AM xxcodercnc: damn looks good.
06:20 AM xxcodercnc: im using mdf only for surfical stuff from now on
06:21 AM xxcodercnc: it dont work as test cut stuff
06:23 AM MacGalempsy: well guys. im going to bed. catch ya later.
06:25 AM jthornton: night
06:25 AM XXCoder: wow
06:25 AM jthornton: just found my old EMC2 BDI disk that I never could get to install lol
06:26 AM XXCoder: jt it looks great lemme upload a video
06:26 AM jthornton: ok
06:28 AM XXCoder: https://youtu.be/rf-7T2a3_tk short but fairly sucky video, making world one
06:30 AM XXCoder: https://youtu.be/kZXK1ljoxF8
06:31 AM jthornton: where did you get the G code for the world texture map?
06:31 AM XXCoder: I didnt heh
06:32 AM XXCoder: I found a picture that works well. lemme get link
06:32 AM jthornton: oh you did the photo to g code thing
06:32 AM XXCoder: https://static-2.gumroad.com/res/gumroad/5387571460549/asset_previews/ea0c5e84f29b3706697ed47039d7a930/retina/Earth_2k_Disp_Preview_v001.jpg
06:32 AM XXCoder: yeah. search term "displacement map"
06:32 AM XXCoder: its pretty amazing.
06:33 AM XXCoder: I used "normalize" so guess why its so extra mountious
06:34 AM R2E4_bevins: thats cool...
06:34 AM XXCoder: yeah. thanks
06:36 AM * Loetmichel_ just makes a new sacrificial plate for the vacuum table on the mill... 2035 drills 3.175mm... and then 2035 drills 0.8mm a bit deeper... and all in a 6mm thick 600mm*400mm Pertinax sheet... MAAAN that takes forever... and stinks :-(
06:37 AM Loetmichel_: (the old one was down to 1.5mm thickness)
06:37 AM XXCoder: ugh over 2k holes
06:37 AM Loetmichel_: more like 4k holes
06:37 AM Loetmichel_: i make them stepped
06:37 AM Loetmichel_: 3mm wide 5mm down, 0.8mm drill thru
06:38 AM SpeedEvil: XXCoder: LASER!
06:38 AM XXCoder: lol
06:39 AM XXCoder: speed laser what?
06:39 AM SpeedEvil: I misread
06:39 AM SpeedEvil: Loetmichel_:
06:39 AM XXCoder: lol
06:39 AM XXCoder: did you see video speed?
06:40 AM Loetmichel_: SpeedEvil: stinks even worse in pertinax
06:40 AM XXCoder: fanastic cut :D so detailed!
06:40 AM Loetmichel_: and i wonder how you would make stepped holes with a laser
06:40 AM SpeedEvil: Impressive
06:40 AM SpeedEvil: Loetmichel_: 5 axis
06:40 AM SpeedEvil: Make cones
06:42 AM XXCoder: theres cone mills
06:43 AM XXCoder: plunge at places, all cones and done
06:53 AM Loetmichel_: hmmm
06:54 AM Loetmichel_: wouldt really work because i face off the plate every now and then when it gets to "roller coaster" because of the mulling thru
06:57 AM XXCoder: oh too bad
07:20 AM R2E4_bevins: Is it suppose to be M6 T1 or T1 M6?
07:20 AM XXCoder: usually set tool first, then command change
07:21 AM XXCoder: some machines support setting tool right after tool change and just do m6 at end of cut for previous tool. good, expecially on machines where toolchanges takes forever
07:22 AM jthornton: I've always used T1 then M6
07:22 AM jthornton: T = Tool Prepare
07:23 AM R2E4_bevins: ok, just checking, for some reason I thought it was the other way around, then the docs sayT previous or previous line. so Thanks
07:25 AM jthornton: try a M6 before a Tn
07:26 AM XXCoder: like many gcode stuff, it depends on machine
07:26 AM XXCoder: machine I hate, okuma, dont even allow you to change t1 to t1. it would error out. most other machines just shrug and keep going
07:34 AM Loetmichel_: XXCoder: i depend on that
07:34 AM XXCoder: why disallow same tool change?
07:35 AM Loetmichel_: i do my CNC files als plot files, then in BoCNC ("postprocessor") i will give different colours diofferent depths of cut
07:35 AM Loetmichel_: ... after that i edit the gcode tochange all T2, t3.. tx to T1
07:35 AM Loetmichel_: so i will usually have a few 100 T1 M6 in my code
07:36 AM XXCoder: oh t1 t2 then t1 is fine
07:36 AM Loetmichel_: linuxcnc just shrugs... would hate to have to manually delete them from the code
07:36 AM Loetmichel_: ;)
07:36 AM XXCoder: im talking about t1 direct to t1
07:36 AM Loetmichel_: thats what i said
07:36 AM XXCoder: yeah shurgging and keep going is normal behivor
07:36 AM Loetmichel_: BoCNC makes tools from different pens in hpgl
07:36 AM XXCoder: okuma will error out and stop
07:37 AM Loetmichel_: after that i just search and replace "t2" to "T1", then T3 to T1 and so on
07:37 AM Loetmichel_: leaving me with 100s of T1 in the code
07:38 AM Loetmichel_: i usually use one colour for inner holes, one colour for bending slots (half depth) and one colour for outline on my sheet metal works
07:39 AM XXCoder: decent idea though why not just search and remove tn m6
07:40 AM Loetmichel_: resulting in things like this: http://www.cyrom.org/palbum/main.php?g2_itemId=14160
07:41 AM Loetmichel_: could do that
07:41 AM XXCoder: nice
07:41 AM Loetmichel_: but the T* are useful as "breakpoints"
07:41 AM XXCoder: I guess my router could do that also, though I got no bender to ben into say boxes lol
07:41 AM XXCoder: guess so
07:41 AM Loetmichel_: i have no bender either
07:41 AM Loetmichel_: see at the parts there that are NOT bent
07:42 AM Loetmichel_: i bend them by hand M;)
07:42 AM XXCoder: sharp inside corners not so possible for my machine heh
07:42 AM Loetmichel_: -M
07:42 AM XXCoder: theres easy (apparently) to make benders
07:42 AM XXCoder: since youg ot machine to make parts for that.
07:45 AM Loetmichel_: http://www.cyrom.org/palbum/main.php?g2_itemId=14877&g2_imageViewsIndex=1
07:45 AM Loetmichel_: compare that to the drawing:
07:45 AM Loetmichel_: http://www.cyrom.org/palbum/main.php?g2_itemId=14874&g2_imageViewsIndex=1
07:45 AM XXCoder: I cant wait to try make stuff like that
07:46 AM Loetmichel_: i do slots at all the bending points, half material thickness
07:46 AM Loetmichel_: so i can bend them by hand and they bend exactly wher ei want them to
07:46 AM XXCoder: V cuts?
07:46 AM Loetmichel_: no, normal slots
07:46 AM Loetmichel_: 2mm wide
07:46 AM Loetmichel_: for 1.5mm thick aluminium
07:47 AM Loetmichel_: i could use V slots... but i dont have a 89° Vslot cutter
07:47 AM XXCoder: oh interesting
07:47 AM Loetmichel_: so i use a standard square one
07:48 AM Loetmichel_: just made another one of these for a customer last week. took me about 4 hours of milling and 20 minutes of mounting it... -> http://www.cyrom.org/palbum/main.php?g2_itemId=15862&g2_imageViewsIndex=1
07:49 AM Loetmichel_: ... you should have seen the faces of the customer when i bent it in a mere few secodns freehand :-)
07:49 AM Loetmichel_: he looked as if he had encountered superman ;)
07:49 AM Loetmichel_: its a bit like aluminium origami ;)
07:51 AM XXCoder: all 4 parts 4 hours or 4 hour each?
07:51 AM XXCoder: how do you make sharp corners with mill??
07:52 AM Loetmichel_: 4 hours milling time for all parts
07:52 AM Loetmichel_: i dont
07:52 AM Deejay: you need multi-head milling machine
07:52 AM Deejay: all holes for one row at once
07:52 AM Loetmichel_: i use a 2mm mill bit and drive diagonally in the corners about 0,7mm where a part with sharp corners has to fit
07:53 AM Loetmichel_: Deejay: wouldnt work... its different on each part
07:53 AM Deejay: oh
07:53 AM Loetmichel_: usually only make prototypes here
07:53 AM XXCoder: great for productoon but his seems one offs and such
07:53 AM Loetmichel_: the series go out to an "blechpatscher" ( sheet metal guy )
07:54 AM Deejay: :)
07:54 AM XXCoder: drive diagally?
07:54 AM Loetmichel_: yeah, XXCoder. mostly one offs and single digit series inhouse
07:54 AM Loetmichel_: all larger volume go out
07:54 AM Loetmichel_: diagonally
07:54 AM XXCoder: yeah cant visualize that
07:56 AM Loetmichel_: \__________/
07:56 AM Loetmichel_: | |
07:56 AM Loetmichel_: | |
07:56 AM Loetmichel_: |_________|
07:56 AM Loetmichel_: */ \
07:56 AM Loetmichel_: ./ \
07:56 AM Loetmichel_: you get the picture ?
07:57 AM Loetmichel_: ignore the asterisk and the last line
07:57 AM Loetmichel_: thats the path the mill bit follows
07:58 AM XXCoder: so dialogally in xy space, then stright to corner, go out diagially
07:58 AM XXCoder: repeat for next 2 corners
07:58 AM Loetmichel_: all 4 corners, yes
07:59 AM XXCoder: so it leaves a round cut outwards of corners. good for protoype as final would just use puncher
07:59 AM Loetmichel_: and only so far that the radius of the tool is OUTSIDE of the thought "sharp corner"
07:59 AM Loetmichel_: yes
08:00 AM XXCoder: nice
08:00 AM XXCoder: its also nice for corner bolting pattern if that is needed
08:02 AM XXCoder: well bedtime later
08:06 AM Longbow: any HAL gurus here? :)
08:06 AM Longbow: how do you compute basic algoritmic operations?
08:07 AM Longbow: I am making a spindle tacho - RPM wtich pyvcp
08:07 AM Longbow: *with
08:07 AM Longbow: I have an encoder 1800 ppr on the spindle
08:07 AM Longbow: I can read it. Now I need to divide the output by 1800...
08:07 AM Longbow: do I have to make a HAL component for that?
08:07 AM XXCoder: to get [0-1) range of value?
08:08 AM XXCoder: doh going later
08:09 AM Longbow: I am reading 40000
08:09 AM Longbow: to get the real RPM I have to divide by 1800 and then multiply by 60 for minutes
08:18 AM Longbow: HAL components are written in C?
08:22 AM archivist: is it an AB encoder, then you have 4 edges per cycle
08:44 AM archivist: Longbow, what are you thinking of writing a hal comp for?
09:30 AM JT-Shop: hi ho hi ho it's off to the industrial park I go
09:34 AM pcw_home: Longbow: spindle encoder scaling should be set so you get spindle position in turns (this does not need any hal components)
09:40 AM pcw_home: When the spindle encoder is scaled properly, the encoder velocity will be scaled in RPS
09:40 AM pcw_home: you can use the "scale" component to scale this to RPM
11:03 AM jym: archivist: Don't now if you care, but this looks like a nice lil wood stove... https://www.machinemart.co.uk/p/clarke-barrel-ii-8kw-cast-iron-wood-burning-st/
11:12 AM archivist: little and expensive
11:34 AM jym: archivist: Inexpensive compared to here, but you don't have to deal with EPA BS
11:36 AM archivist: nor do you soon :)
11:40 AM jym: Ha, every stove MUST be EPA certified or it won't even be shipped to Calif/Washington, I've already had to deal with the whole EPA crap adn contact the companys attorney to get it resolved.
11:41 AM archivist: and our clean air act predates your EPA probably The Clean Air Act 1956 was an Act of the Parliament of the United Kingdom passed in response to London's Great Smog of 1952.
11:42 AM roycroft: the environmental protection agency was created by executive order in 1973 during the nixon administration
11:42 AM roycroft: so yes, you beat us by a couple decades
11:42 AM jym: I didn't see any "certification" on that stove
11:42 AM archivist: its the fuel we burn in certain areas
11:43 AM roycroft: now let's see if iron lady ii can dismantle your clean air act faster than our orange face can dismantle the epa
11:43 AM archivist: hehe
11:44 AM archivist: she is too busy kicking the EU
11:44 AM roycroft: and worrying about the scottish problem
11:45 AM roycroft: although i suspect she isn't giving that too much thought
11:45 AM CaptHindsight: smog is all fake, made up pinko leftist FUD to steal your money, turn your boys into girls (and vice versa) :) :)
11:45 AM archivist: the scots have their own bitch in charge
11:45 AM CaptHindsight: or what I've heard
11:52 AM roycroft: interesting times in both our countries, that's all that i can say at this point
12:21 PM Loetmichel_: roycroft: interesting times indeed
12:22 PM Loetmichel_: which one of you has managed to get cursed by a chinese? ( "may you live in interesting times!" )
01:32 PM cpresser_ is now known as cpresser
02:20 PM MrSunshine: hi, so i got this rather "flimsy part" .. (made from 80x80mm tubing with 5mm wall thickness) and i need some surfaces of it planed of .. tho i do not want twist in it after its planed .. any ideas on how to hold it in say a milling machine ?
02:20 PM MrSunshine: http://a360.co/2lrH5h4
02:20 PM MrSunshine: its 1.5 meters long and 270mm wide
02:22 PM MrSunshine: im thinking of making a bracket to hold it on the thin plate at the end on center, .. so its supported on 3 places and not 4
02:23 PM MrSunshine: after the rails are straight the rest of the operations are quite trivial .. but the rails are a pita to get straight and paralell it feels like =)
04:26 PM Deejay: gn8
06:25 PM JT-Shop: whew, I'm calling it a day
07:28 PM Frank_10: hello
07:39 PM R2E4_bevins: Hello
07:45 PM MacGalempsy: hello
07:49 PM Tom_L: 43770
07:49 PM R2E4_bevins: WTH is 43770?
07:49 PM Tom_L: get a mirror and find out
07:49 PM R2E4_bevins: hello in numbers upside down and backwards?
07:50 PM R2E4_bevins: ah yeah, mirroed
07:50 PM R2E4_bevins: lol
07:50 PM R2E4_bevins: http://www.kijiji.ca/v-business-industrial/canada/biesse-rover-346-cnc-router/c346142?channelId=101
07:50 PM R2E4_bevins: I could do that one in a week.
07:56 PM malcom2073: Nice, big one
07:57 PM R2E4_bevins: I just did one of those in my shop in three weeks. Just have the ATC to do.
08:06 PM MacGalempsy: retrofit or ground up build?
08:06 PM MacGalempsy: hey malcom2073 how did the techmeet go?
08:08 PM malcom2073: MacGalempsy: Went well! Had a lot of fun
08:09 PM MacGalempsy: did u get sell or trade?
08:10 PM MacGalempsy: oops minus get
08:21 PM MacGalempsy: http://www.thebranfordgroup.com/DNN3/Auction/CREA0317.aspx
08:21 PM MacGalempsy: a local auction... hmmm
08:24 PM MacGalempsy: few things of interest.
08:24 PM MacGalempsy: 0
08:28 PM malcom2073: Yeah I sold some random stuff, made about $60
08:35 PM MacGalempsy: hey pete how goes it?
08:38 PM BeachBumPete: Hey mac
08:40 PM MacGalempsy: makin chips tonight? its dead out here
08:45 PM BeachBumPete: yeah I am working on another prototype
08:49 PM MacGalempsy: sweet.
08:50 PM BeachBumPete: yeah I need to get working on this damn CNC lathe too
08:51 PM MacGalempsy: lol. i feel ya on the projects list. being away from home for so long has mine backing up too
08:54 PM BeachBumPete: yup this weekend I did some projects around the house, installed some nice new shelving and closet rods in my kids room and mowed the lawn, trimmed the palm tree fronds that were dead and annoying the crap out of me
08:54 PM BeachBumPete: I have quite a few rails to machine here so that took away from my CNC time...
08:55 PM MacGalempsy: gosh. im fearing the yard work...
08:57 PM BeachBumPete: I did buy myself a nice new toy tho ;)
08:57 PM roycroft: it's solidworks night for me
08:58 PM roycroft: several design projects to work on
08:58 PM roycroft: i wish this cold weather would just be over
08:58 PM MacGalempsy: cool. ta
08:59 PM MacGalempsy: that always fun
08:59 PM roycroft: i have a hard time working in the shop when it's so bloody cold
08:59 PM roycroft: but march is just around the corner, so we'll get some nice days soon
08:59 PM BeachBumPete: I do my CAD CAM work inside when I lived in Tennessee
09:00 PM roycroft: yes, i do cad work inside
09:00 PM roycroft: which is why i spend the winter designing/planning
09:01 PM roycroft: and the rest of the year making stuff
09:01 PM BeachBumPete: anyway when I lived in Tennessee I had bought myself a neat M audio Midi Controller keyboard and some nice Studio Monitor speakers and I had to sell it all when I got sick and had to have surgery ;)
09:01 PM roycroft: what i need to do is start making money again when i make stuff
09:02 PM roycroft: then i can justify doing some remodeling of the shop - new door, insulation, and proper heat
09:02 PM roycroft: and i can keep it warm year-round
09:02 PM BeachBumPete: so I got a few nice rails sold and had some money so I picked up a really nice used M-audio Keystation Pro88 ES and some of the same studio monitor speakers from a local guy for a great price ;)
09:03 PM MacGalempsy: making money is always good.
09:03 PM MacGalempsy: sweet keyboard
09:03 PM BeachBumPete: I have not really bought myself anything in quite some time
09:03 PM MacGalempsy: you bought warmer winters ;)
09:03 PM R2E4_bevins: I've done some audio recording myself...... in the basement
09:03 PM BeachBumPete: yeah man it is REALLY nice even nicer than the brand new one I used to have which was only 61 keys
09:04 PM BeachBumPete: Yeah man I did do that I suppose. I LOVE my new house so that counts doesn't it LOL
09:04 PM BeachBumPete: R2E4_bevins Oh yeah man it is fun isnt it
09:04 PM R2E4_bevins: Its been a while but I got into it really heavy.
09:04 PM BeachBumPete: I got some neat vst files downloaded
09:04 PM BeachBumPete: I am a big fan of ambient music
09:05 PM R2E4_bevins: My wife is a music teacher, tookl a hard disc recorder in and recorded the kids, took it back homne mixed it and had cd made. with cover art that kids did.
09:05 PM R2E4_bevins: It is fun stuff.
09:05 PM BeachBumPete: I absolutely love Vangelis and have always wanted to try to recreat the Blade runner type music
09:06 PM BeachBumPete: I found this great video online where a guy basically used a very similar setup and recreated the intro theme music using some free synths he downloaded
09:06 PM BeachBumPete: He was kind enough to share that information
09:06 PM R2E4_bevins: I surfaced 5 wood tables today on the new machine with LCNC.... dont mean to change the subject...lol
09:06 PM BeachBumPete: I downloaded it on Sunday and was screwing around with it.
09:07 PM BeachBumPete: I must admit it sounded almost exactly like the brassy deep dark sounds from Blade Runner
09:07 PM BeachBumPete: VERY VERY COOL
09:07 PM BeachBumPete: Glad your CNC is working well for you
09:07 PM BeachBumPete: BRB
09:09 PM MacGalempsy: Pete you like Cafe del Mar?
09:09 PM BeachBumPete: I swear I thought CAD CAM and CNC programs were amazingly adaptable and complex....then I started playing with music software LOL
09:09 PM BeachBumPete: Not familiar with it I don't think is it a music group or something?
09:10 PM MacGalempsy: its a bar in ibiza and the theme is night time and sunrise
09:10 PM BeachBumPete: https://www.youtube.com/watch?v=Oo9ylMylZDc
09:11 PM MacGalempsy: there are several albums, usually ambient
09:11 PM BeachBumPete: I gotta check it out..is it good?
09:12 PM BeachBumPete: Oh yeah I also went to Guitar Center and bought this SWEET two tier keyboard rack so I can set my laptop on it. It is also possible to add another tier when I get another keyboard
09:13 PM MacGalempsy: very relaxing imo
09:14 PM BeachBumPete: That is what I like. relaxing
09:14 PM MacGalempsy: Mix between lounge and ambiemt
09:14 PM BeachBumPete: Have you ever heard of Richard Burmer?
09:14 PM BeachBumPete: there are quite a few ambient artists I enjoy
09:15 PM R2E4_bevins: American composer sound designer
09:15 PM BeachBumPete: Honeslty I just want to learn to play the keyboard
09:16 PM MacGalempsy: https://youtu.be/5HzeplEuQfk
09:16 PM BeachBumPete: https://www.youtube.com/watch?v=3b1xJYCrKDU The master at work ;)
09:18 PM BeachBumPete: I made a damn forward account in Google for my new email so I still get emails from old customers but can have a new email.
09:18 PM BeachBumPete: for some reason today my cellphone got an alert message from Google saying I had to login again
09:18 PM BeachBumPete: now I cannot access the new account. Pissing me off!!
09:19 PM roycroft: thank you for once again proving that taking the easy route and using major mail providers is more of a hassle in the long run :)
09:20 PM BeachBumPete: well honestly this is the first time I have ever had an issue in many years of use?
09:20 PM roycroft: it happens fairly frequently
09:20 PM BeachBumPete: not really sure what happens
09:20 PM BeachBumPete: not to me
09:21 PM MacGalempsy: that happens to me about 1 time a year, or so
09:21 PM roycroft: i can't begin to count the number of customers who have lert us (i work for an independent, mom and pop isp) to go on to the big world of google mail and amazon hosting, etc
09:21 PM BeachBumPete: been using the same account for shit almost a decade
09:21 PM roycroft: and end up coming back to us when things go awry, and they can't get any help
09:21 PM MacGalempsy: i did notice tho that a recent search got me a "random" call
09:21 PM roycroft: yes, of course
09:22 PM MacGalempsy: cant wait to root my tablet...
09:22 PM roycroft: because their "free" accounts are just a way for them to unleash their data-mining, privacy-ignoring infrastructure on you
09:22 PM MacGalempsy: get all that crap bloatware off
09:23 PM BeachBumPete: what do you mean a random call?
09:23 PM roycroft: use duck duck go as your search engine and you won't be leaving fingerprints around
09:23 PM roycroft: use google and they'll know every time you pee before long
09:23 PM BeachBumPete: I like Brian Eno a bit too
09:23 PM BeachBumPete: sure they will...but they also provide a lot of things in exchange
09:24 PM roycroft: yes
09:24 PM BeachBumPete: Facebook seems to me to be really bad about this
09:24 PM roycroft: i won't deny that
09:24 PM roycroft: it's a matter of deciding if the tradeoff is worth it
09:24 PM roycroft: i value my privacy too much
09:24 PM roycroft: i shun google as much as possible
09:24 PM roycroft: i have no "social media presence"
09:25 PM roycroft: i think facebook is one of the most destructive things unleashed on society in our entire history
09:25 PM roycroft: and a the same time one of the most useful things
09:25 PM BeachBumPete: I quite enjoy facebook and use it for my business as well
09:25 PM roycroft: but i refuse to use facebook, twitter, etc.
09:25 PM BeachBumPete: allows me to reach customers around the world
09:25 PM roycroft: websites can do that too :)
09:25 PM BeachBumPete: just sold a rail to a guy in sweden yesterday
09:26 PM BeachBumPete: I had a simple website did not gain me much of anything
09:26 PM BeachBumPete: but I get lots of likes and views on facebook and sometimes they result in sales
09:26 PM MacGalempsy: i like the constant flow of memes that let me enjoy a certain style of comedy without having to post it myself
09:26 PM roycroft: it takes time and it takes effort to operate a successful website
09:27 PM roycroft: i know i'm not by any means in the majority in how i feel about social media
09:27 PM BeachBumPete: yeah I suppose but I have better things to do with my time
09:27 PM roycroft: and i'm not trying to influence others to act as i do
09:27 PM BeachBumPete: if facebook did not work for me believe me I would not be using it
09:27 PM roycroft: i do like to increase awareness of the downsides though
09:28 PM BeachBumPete: BRB
09:29 PM roycroft: i promise not to get political beyond this brief observation, but my sense is that you have more concerns about government intrusion on your privacy, and while i'm concerned about government data collection, my greater concern is about corporate intrusion
09:29 PM roycroft: that would explain why i'm so anti-social media
09:29 PM roycroft: in part
09:33 PM SpeedEvil: The two of course leverage. Can't compel a company to produce what it doesn't have.
09:34 PM BeachBumPete: I honestly have nothing to hide but I understand your view
09:34 PM roycroft: i have nothing to hide either
09:34 PM BeachBumPete: I never said you did
09:34 PM roycroft: no, you did not
09:35 PM roycroft: i'm just being clear :)
09:36 PM roycroft: people are becoming increasingly aware of and concerned about personal privacy issues, especially online privacy
09:36 PM roycroft: i think we'll probably get to a point where we can have the benefits of social media without all the negatives
09:37 PM jdh: how? you are the product.
09:37 PM BeachBumPete: anyway I have enjoyed this new keyboard quite a bit. https://www.youtube.com/watch?v=3ynoHoJIbDk This is the one I got I need to find a good quality Grand Piano vst. The one I have is decent but there are nicer ones
09:38 PM roycroft: i'm not the product :)
09:38 PM roycroft: and fewer and fewer people are being the product
09:39 PM roycroft: i'm not sure we've hit peak facebook yet
09:39 PM roycroft: but we're close, if not there
09:41 PM BeachBumPete: I was at Guitar center and M-audio now has a neat little keyboard syth unit that I might try to get used in awhile or something.
09:41 PM BeachBumPete: It is called the venom or something like that.
09:42 PM BeachBumPete: I wish I could afford a really nice unit like an Yamaha Motif or Korg Kronos or something but hey I am cheap ;)
09:43 PM BeachBumPete: R2E4_bevins what kind of keyboard or mixer are you using?
09:44 PM R2E4_bevins: I have an opld korg synth from the 70's, and a DX7, and my wife has a Yamaha upright.
09:44 PM BeachBumPete: SWEET
09:44 PM BeachBumPete: which korg?
09:45 PM R2E4_bevins: Juno 60
09:45 PM BeachBumPete: OH man that is one of the nicer ones...
09:45 PM R2E4_bevins: Roland
09:45 PM BeachBumPete: I have a vst based on that
09:45 PM BeachBumPete: how do you like the DX7
09:45 PM BeachBumPete: Yamaha makes good stuff
09:46 PM BeachBumPete: Believe it or not but Vangelis used an early Yamaha Syth engine to create most of the sounds in the Blade runner Movie
09:46 PM BeachBumPete: I think it was a CS70 or CS80 or something
09:46 PM R2E4_bevins: analog synth or digital?
09:47 PM BeachBumPete: Not sure what it was but it was Yamaha
09:47 PM BeachBumPete: CS70 I think
09:48 PM R2E4_bevins: thats analog
09:48 PM BeachBumPete: Yamaha's Tyros is amazing
09:48 PM BeachBumPete: I have a friend that has one I work with and I went to visit him just to play with it LOL
09:49 PM R2E4_bevins: lol, there fun
09:49 PM BeachBumPete: its like 5 grand
09:50 PM BeachBumPete: I am still trying to wrap my head around how to record beats and fill ins etc.
09:50 PM BeachBumPete: what DAW are you using?
09:50 PM R2E4_bevins: N-Tracks
09:51 PM R2E4_bevins: I havent used it in years. Havent done much by way of recording for a while now.
09:51 PM BeachBumPete: I downloaded Cocos Reaper and have been using it
09:51 PM BeachBumPete: I used to have a trial of FL studio
09:51 PM BeachBumPete: they are similar in many ways
09:51 PM BeachBumPete: at least from what I can remember
09:51 PM R2E4_bevins: N-track studio is nto expensive....
09:52 PM BeachBumPete: My friend uses Ableton
09:52 PM BeachBumPete: no cocos reaper for personal use is like $60
09:52 PM R2E4_bevins: N-Tracks is $100 I think
09:52 PM R2E4_bevins: My friend has a class C studio with Apple stuff. He does amazing work.
09:52 PM BeachBumPete: the full blown version of Reaper is like $235 or something like that
09:53 PM BeachBumPete: I am just amusing myself here and trying to learn how to play the keyboard really nothing too serious
09:53 PM BeachBumPete: I am also trying to learn the guitar I bought awhile back just a six string acoustic takameni
09:58 PM Tom_L: yamaha does make a quality product
10:22 PM os1r1s: Tom_L Got a minute for fixturing advice/
10:26 PM Tom_L: just one or two
10:48 PM os1r1s: Tom_L So I milled this part last night. Tonight I flipped it over and did the other side. The problem is the alignment is off by just a little bit. Any suggestions on easy ways to realign easily?
10:48 PM os1r1s: https://www.dropbox.com/s/8csb6ocd55jox6z/eustaluxend.jpg?dl=0
10:57 PM Tom_L: is it off in your cad model?
10:57 PM Tom_L: after you machined the perimeter, there is less metal there for side two to touch off from
10:58 PM Tom_L: that's a fairly common mistake in cad modeling
10:58 PM cradek: if that hole goes all the way through, cut it with a boring head and then you can center on it from either side
10:58 PM Tom_L: ^^
10:58 PM cradek: it will be perfect
10:58 PM Tom_L: that works
10:58 PM cradek: that point plus the rotation of your vise on any flat face locates the part
10:58 PM roycroft: or mill part of the left side all the way down and touch off on that
10:58 PM Tom_L: use your hole center as the start of side two
10:59 PM Tom_L: there's other ways but that works good
10:59 PM cradek: heck even if it's just reamed it'll work fine, looks big enough to ream straight
11:00 PM Tom_L: it's a common mistake in cad to cut one side using the block as the edge then flipping it in cad and that edge has been milled away
11:00 PM Tom_L: if you use the edge, make sure it matches the model :)
11:01 PM Tom_L: unless it's just a backlash problem
11:05 PM diginet_ is now known as diginet
11:08 PM os1r1s: Tom_L cradek The thing is, I'm off by about .5mm
11:08 PM os1r1s: I'm pretty sure its not a cad error. I think its how I'm setting X/Y
11:09 PM os1r1s: But the hole idea sounds pretty good. With a 5/8 hole, its gonna be spot on
11:22 PM MacGalempsy: os1r1s how are you touching off the workpiece?
11:22 PM os1r1s: MacGalempsy Putting a bit up against the side until I can't pull a piece of paper out
11:23 PM MacGalempsy: that should give less than .5mm
11:24 PM MacGalempsy: what is the bit dia?
11:24 PM os1r1s: I used a 5/8 drill bit to touch off
11:25 PM os1r1s: I often use end mills, but this had such large flat surfaces it seemed perfect
11:26 PM MacGalempsy: so that .5mm is like .019". steppers or servo?
11:26 PM os1r1s: servo
11:26 PM MacGalempsy: how does the ferror look after tuning?
11:26 PM os1r1s: I haven't checked
11:27 PM os1r1s: But I would think if it was setting related, the multiple layers would be off ..
11:27 PM MacGalempsy: good point.
11:28 PM os1r1s: I have an edge finder, but that seems arguably less accurat
11:28 PM os1r1s: I could make it an electrical probe ...
11:28 PM os1r1s: But it would be nice to fixture it so I didn't need to
11:29 PM MacGalempsy: really. thats interesting that the edge finder is less accurate
11:29 PM os1r1s: do you think a spinning edge finder would be more accurate?
11:30 PM MacGalempsy: you are talking about the cylinder that jumps off center right?
11:30 PM os1r1s: yep
11:30 PM os1r1s: Made by fisher I think
11:30 PM MacGalempsy: i would think repeatibility would be better
11:31 PM os1r1s: k. I'll have to get that a shot
11:31 PM os1r1s: I'm hoping a vise stop will help
11:31 PM MacGalempsy: try a few times on some scrap and see if its the same each time
11:32 PM MacGalempsy: also, check the squareness of the stop
11:32 PM os1r1s: I dont' have the stop yet, but it shoudl be here Wednesday
11:33 PM MacGalempsy: opps i meant squareness of the stock
11:34 PM MacGalempsy: how many times did you have the problem? once, twice?
11:36 PM os1r1s: MacGalempsy This is teh first time I've tried it
11:39 PM MacGalempsy: ah. ok. try a few times with the edge finder and see if it improves.
11:39 PM MacGalempsy: .5mm on squareness is not much of you faced it yourself
11:40 PM os1r1s: I'm not following?
11:44 PM MacGalempsy: so you said you are off by .5mm. if your workpiece is not square then when you flip it, it could be slightly offset
11:45 PM os1r1s: Thats a good point
