[00:04:56] <XXCoder> "Minimum pressure: 2V "
[00:05:04] <XXCoder> isnt Amps "pressure"?
[00:05:25] <XXCoder> ah im wrong
[00:05:31] <XXCoder> https://s-media-cache-ak0.pinimg.com/564x/02/39/ea/0239eae3275af8aa7c84bb47d41ed48c.jpg
[00:09:07] <SpeedEvil> As a general point, if they don't produce a clear listing, simply avoid
[00:09:42] <XXCoder> yeah its clear now that I clared out my confusion heh
[00:30:55] <XXCoder> SpeedEvil: hows ya
[00:43:17] <XXCoder> HMMM http://www.ebay.com/itm/DC-24V-to-12V-3A-20W-Car-Camera-Monitoring-Power-Supply-Voltage-Regulator-F5-/292021867085
[00:47:55] <XXCoder> http://www.ebay.com/itm/24V-12V-To-5V-DC-DC-Converter-USB-Step-Down-Module-Output-Power-Adapter/132059292497 nice for 5v
[00:48:11] <XXCoder> can either use tiny usb cable or just splice usb connector off and use wires
[01:17:02] <XXCoder> okay ordered 24v-12v and 24v-5v regulators :D
[01:17:10] <XXCoder> now to wait 100 years for it to arrive
[03:10:10] <Deejay> moin
[03:10:28] <XXCoder> yo
[03:36:14] <kyle___> dumb question incoming
[03:36:31] <kyle___> are supported rails usually attached solidly to the support?
[03:37:04] <kyle___> logic tells me they are, but i've seen a few that looked like they weren't
[03:37:14] <XXCoder> mine are but I dont know
[03:37:44] <kyle___> hm okay
[03:37:49] <archivist> attached on many points
[03:37:53] <kyle___> anyone seen any good deals on 16mm or so rail lately?
[03:38:47] <kyle___> also, how does square rail usually compare to round types?
[03:39:57] <archivist> often the round is less good
[03:40:45] <archivist> all depends on what the machine is designed/used for
[03:40:59] <kyle___> crushing my hopes and dreams mainly
[03:41:20] <kyle___> but a little bit of aluminum milling on the side
[03:41:25] <archivist> good learning exercise
[03:41:41] <kyle___> it'll keep me busy while i save some money for a real machine
[03:42:24] <archivist> my first was homebrew and did have problems, so those parts were reworked
[03:43:28] <kyle___> yeah, as long as it works to some capacity I think I'll be pretty happy
[03:43:46] <kyle___> I really don't expect to make anything useful with it
[03:44:37] <archivist> I scrapped a rubbish lathe to use the headstock as the mill spindle
[03:44:55] <kyle___> awesome
[03:45:03] <kyle___> how well did it work?
[03:45:26] <archivist> it has taper rollers bearings so as a spindle it is ok but not fast
[03:45:54] <kyle___> i'll probably end up with a $200-300 thing from aliexpress
[03:46:06] <archivist> the bed became the column, needed beefing up too flexible
[03:46:17] <kyle___> makes sense
[03:46:25] <kyle___> https://www.adafruit.com/products/1861 hmm how awful would this be?
[03:46:43] <kyle___> two of these should give me the right amount of support
[03:47:26] <archivist> XY were from an old tool setting thing, friction too high and travels too short, later fitted rails on one axis
[03:47:50] <kyle___> was this CNC?
[03:48:07] <archivist> that looks like hiwin rail
[03:48:21] <archivist> yes
[03:48:22] <kyle___> yeah, think that's the impression they're going for
[03:48:43] <kyle___> "Note that these are 'hobby' grade slide rails" at least adafruit is honest
[03:49:18] <archivist> you can get hiwin on ebay for not a lot more
[03:49:42] <kyle___> yeah you're right
[03:49:44] <archivist> remember you can reuse the slides on later builds
[03:49:59] <kyle___> yeah, maybe shouldn't cheap out so much then
[03:50:27] <kyle___> http://www.ebay.com/itm/HIWIN-HGR15-15mm-Linear-Rail-Guide-2pc-HGH15CA-Rail-Block-Slider-CNC-Kit/201575952093?_trksid=p2045573.c100507.m3226&_trkparms=aid%3D555017%26algo%3DPL.CASSINI%26ao%3D1%26asc%3D41451%26meid%3D6353bfd9c5e5403b9cf9efe1b650e15b%26pid%3D100507%26rk%3D1%26rkt%3D1%26
[03:50:30] <kyle___> yikes that link
[03:50:32] <XXCoder> I still has set of SBR rails
[03:50:37] <XXCoder> no idea what to do with em.
[03:50:44] <archivist> I friend had an assortment of rails he had not used, so convinced him to sell :)
[03:50:45] <XXCoder> ky you can cut out everything past ?
[03:50:52] <kyle___> yeah
[03:50:53] <XXCoder> incluiding the ? itself
[03:50:59] <kyle___> didn't realize it was so long though
[03:51:18] <kyle___> muscle memory made me do it!
[03:51:20] <archivist> the rest is tracking after the ?
[03:51:28] <XXCoder> I might make a plotter HMMMMM
[03:51:42] <kyle___> you could sell them to me!
[03:51:43] <XXCoder> would be interesting, and I has all screws and rails I need.
[03:52:03] <XXCoder> may be good
[03:52:10] <kyle___> do it
[03:52:23] <XXCoder> kyle___: shipping them is pretty expensive ya sure heh
[03:52:32] <kyle___> lol yeah this is true
[03:52:34] <XXCoder> and what size you needed?
[03:52:35] <kyle___> depends on where you are
[03:52:45] <kyle___> i'm not sure, maybe you guys could help me pick
[03:52:47] <XXCoder> washington state
[03:52:50] <kyle___> 15mm seems too small for me
[03:52:57] <XXCoder> , usa
[03:52:59] <kyle___> ah i'm in the bay area
[03:53:13] <kyle___> not too far
[03:53:27] <XXCoder> where is bay area?
[03:53:32] <kyle___> california
[03:53:35] <kyle___> san francisco bay
[03:53:37] <XXCoder> ahh
[03:53:54] <kyle___> http://www.ebay.com/itm/HIWIN-L-600mm-Linear-Rail-MGNR12-Guideway-amp-2pcs-Block-Carriage-MGN12C-CNC-DIY-/201464157154?
[03:53:59] <kyle___> oh this is a much better deal
[03:54:08] <kyle___> about the length i need too
[03:54:13] <XXCoder> lemme find orgial prices I bought em at heh
[03:54:33] <kyle___> ah go ahead and make a plotter
[03:54:37] <XXCoder> http://www.ebay.com/itm/250729742630 lol
[03:54:44] <XXCoder> the set I bought
[03:54:47] <kyle___> ah man
[03:54:48] <kyle___> that's cheap
[03:54:54] <kyle___> don't tempt me!
[03:55:03] <XXCoder> crunchy bearings
[03:55:10] <XXCoder> I cleaned mine but yeah crunchy
[03:55:13] <kyle___> hm
[03:55:16] <kyle___> crunchy's no good
[03:55:38] <kyle___> might just take archivist's advice and buy something half-decent so I can reuse it later
[03:55:56] <kyle___> hiwin is in the half-decent range, right?
[03:56:20] <archivist> hiwin is the cheap end of half
[03:56:24] <XXCoder> well even if same quality that type is far better than SBR
[03:56:54] <kyle___> hm, this is MGN so pretty tiny
[03:56:57] <XXCoder> from what I understand that type twists far less than SBR would allow
[03:59:49] <kyle___> maybe I should just dig up the physics knowledge I have and calculate some likely forces
[04:00:04] <XXCoder> theres sims but exp[ensive
[04:00:07] <XXCoder> solidworks
[04:00:16] <kyle___> oh right
[04:00:26] <kyle___> meh, probably faster to use pen and paper
[04:00:44] <kyle___> hiwin claims 0.68kN - 8.93kN dynamic load range
[04:03:05] <archivist> when you speak to rail sales droids, they do mention the real strength/rigidity is the frame they are bolted on
[04:03:26] <kyle___> that's very honest of them
[04:03:42] <XXCoder> I remember also reading that good flatness starts with surface rail rests on also.
[04:04:10] <kyle___> so you're saying I should buy a cheap cast iron surface plate from amazon to mount to?
[04:04:21] <kyle___> that's... actually not that bad of an idea
[04:04:42] <archivist> well new after heat treatment there can be some bend that needs removing by bolting to flat
[04:05:17] <archivist> a surface plate would be reasonable
[04:06:03] <kyle___> cheap ones are about the size I need too
[04:06:15] <archivist> you can get gauge plate in steel and aluminium which is nice and flat
[04:06:38] <XXCoder> whats your planw ith cnc kyle
[04:06:41] <kyle___> yeah, maybe I should check out my local steel supplier
[04:07:01] <kyle___> my plan is to avoid losing some fingers and maybe mill some aluminum
[04:07:43] <kyle___> it'd be fun to make it a manually controlled mill with some handwheels with rotary encoders and an arcade joystick for power feed
[04:08:00] <archivist> one of my axes is now gauge plate aluminium off cuts I got from a scrap yard
[04:09:49] <kyle___> how thick of plate should I be looking at?
[04:11:19] <archivist> as thick as you can afford
[04:11:46] <XXCoder> I'd not recommand breaking bank though
[04:11:52] <kyle___> lol
[04:12:57] <kyle___> what about cast epoxy?
[04:13:14] <kyle___> not sure how flat you can actually get it
[04:14:41] <XXCoder> yeah read website about grinite epoxy
[04:14:45] <XXCoder> its tough material
[04:15:04] <kyle___> lots of people building machines from it
[04:15:06] <XXCoder> flatness no idea though they used embedded strips of metal that they milled for flat then put rails on it.
[04:15:50] <kyle___> yeah
[04:16:06] <kyle___> kinda tough when you don't have a mill
[04:16:20] <kyle___> but hey, I need a surface plate anyway so maybe I could learn scraping
[04:17:39] <XXCoder> how do you get it within range for scaping to work? or does scaping work reardless of initial differences in position, height, angles, so on?
[04:18:11] <kyle___> my impression is that you can start off something that's not actually that flat and it's just more work for oyu
[04:18:28] <archivist> file first
[04:18:37] <kyle___> or that, that's a pretty good idea
[04:19:28] <kyle___> oh wow, that's an interesting idea
[04:19:44] <kyle___> take hockey pucks and drill out a hole for a bolt and use them for leveling feet
[04:21:02] <archivist> hmmm http://www.ebay.co.uk/itm/24-x-24-Heavy-Duty-Cast-Iron-Surface-Plate-Table-/282347564834
[04:21:30] <kyle___> lol, looks like you'd need another surface plate to make it a surface plate again
[04:22:03] <archivist> at that price it is a cheap lump of iron
[04:22:26] <archivist> with the odd it of damage and drilled hole
[04:23:26] <XXCoder> kyle___: you need 3
[04:23:37] <XXCoder> in order to start from nothing to make surface plates
[04:23:46] <XXCoder> 3 plate method
[04:24:02] <kyle___> oh yeah
[04:24:46] <kyle___> yeah, I think I might just use epoxy granite
[04:24:57] <kyle___> sounds fun
[04:25:12] <XXCoder> I wonder if this would work - make 3 epoxy grinite plates, use 3 plate method
[04:25:29] <kyle___> you probably could
[04:25:39] <kyle___> as long as you can reliably scrape it
[04:27:01] <kyle___> welp, it's 2am here, time to head to bed
[04:55:22] <jthornton> morning
[04:55:58] <XXCoder> hey
[05:06:17] <IchGucksLive> hi from a heavy Rainy Germany
[05:07:31] <XXCoder> hey from black wa
[05:07:48] <XXCoder> I ordered 12v and 5v dc-dc convertors
[05:08:05] <XXCoder> so its just case of waiting 100 years for package to arrive.
[05:08:31] <IchGucksLive> bst to go
[05:08:57] <IchGucksLive> why not real 110V to 12V and 110V to 5V
[05:09:04] <XXCoder> whats awesome is that they are all sealed packages, and 5A. eway overkill but I wont need to upgrade ever
[05:09:08] <IchGucksLive> its not that pricy
[05:09:23] <XXCoder> 4 bucks and 5 bucks not much
[05:09:51] <IchGucksLive> Meter the Mount points for shorten to source or gnd
[05:10:09] <IchGucksLive> so no suprice is on
[05:11:03] <XXCoder> ya just need to figure how to do board layout
[05:11:23] <XXCoder> maybe just crudely build a wood board lol
[05:11:26] <XXCoder> or plastic sheet
[05:12:00] <IchGucksLive> why not a EL case at 20USD
[05:12:14] <IchGucksLive> only 3 Axis or 4
[05:12:25] <XXCoder> om amazon or something?
[05:12:44] <IchGucksLive> washington state you are
[05:13:12] <XXCoder> yea
[05:19:34] <IchGucksLive> im not finding somthing good in US
[05:19:43] <IchGucksLive> industrial cabinett
[05:20:29] <XXCoder> I might just build one, but just plastic sheet is ok for now I would think.
[05:20:36] <XXCoder> just add covers to exposed boards
[05:21:04] <IchGucksLive> http://www.ebay.com/itm/11-4-x-8-3-x-3-1-Plastic-Enclosure-Project-Case-DIY-Junction-Box-NEW-/201814607572?
[05:21:56] <XXCoder> pretty compact, but then can buy 2 of em
[05:22:08] <XXCoder> or just leave psus out
[05:22:42] <IchGucksLive> http://stores.ebay.com/ewh-shop/Kunststoff-Gehause-/_i.html?_fsub=2952390014&_sid=109981484&_trksid=p4634.c0.m322
[05:22:52] <IchGucksLive> im looking for things like this
[05:23:34] <XXCoder> heh germany, good for looong words
[05:25:08] <XXCoder> http://www.ebay.com/itm/ABS-Plastic-Enclosure-Connection-Box-Project-Case-Instrument-Shell-250-190-80mm-/171780674350
[05:25:18] <XXCoder> great to add dial displays buttons so on
[05:25:34] <XXCoder> smaller though
[05:25:45] <IchGucksLive> you need 350x200x150
[05:26:05] <XXCoder> yeah was looking for minium of 300mm thats approx one foot
[05:26:19] <XXCoder> think found one
[05:26:48] <XXCoder> http://www.ebay.com/itm/SC1283B-12-DIY-Electronic-Metal-Aluminum-Project-Box-Enclosure-Case-/261375388801
[05:26:57] <XXCoder> still not quite large enough i think
[05:28:33] <XXCoder> right now all electrics is in old soda cardboard box lol
[05:28:42] <XXCoder> its from my old job
[05:30:04] <XXCoder> one I recently linked to is best one so far for ebay
[05:30:22] <IchGucksLive> this is what i use http://www.ebay.de/itm/Kunststoff-Schaltschrank-Wandgehause-Verteilerschrank-Elektrogehause-NEU-OVP/170703114975
[05:30:32] <IchGucksLive> but cand belive its not in the US
[05:31:01] <XXCoder> 400mm longest, 300mm other side. nice size
[05:32:04] <XXCoder> I found one
[05:32:12] <XXCoder> whhhhhew $145 bucks
[05:32:26] <IchGucksLive> there is a other name for that in the us
[05:32:34] <jthornton> I use old computer cases sometimes
[05:32:44] <IchGucksLive> it is world wide Standard cases IP67
[05:33:12] <XXCoder> jt that may be best for me
[05:33:38] <IchGucksLive> Big tower Case and ITX-mini inside all wire
[05:33:44] <IchGucksLive> that is cool
[05:34:42] <XXCoder> can find computer junk place
[05:35:33] <IchGucksLive> till later
[05:35:49] <XXCoder> yeah
[05:46:54] <jthornton> XXCoder: got a photo of your router?
[05:47:13] <XXCoder> not really but a second
[05:47:30] <XXCoder> https://www.aliexpress.com/item/Wood-Lathe-3040-Cnc-Router-Milling-Machine-with-43mm-bracket-Mechanical-Kit-Aluminium-Alloy-Frame/32279070195.html
[05:51:04] <jthornton> looks pretty beefy
[05:51:18] <jthornton> how do the ball screws feel?
[05:51:42] <XXCoder> in what terms?
[05:52:50] <jthornton> sloppy or tight and smooth?
[05:53:03] <XXCoder> ahh pretty good actually, tight and smooth
[05:53:10] <jthornton> nice
[05:54:53] <XXCoder> my machine now has different Z block
[05:55:03] <XXCoder> one to hold 52mm rather than 43
[05:57:01] <jthornton> have you ran the spindle yet?
[05:57:32] <XXCoder> the new one not yet
[05:57:41] <XXCoder> since it is extremely strightforward
[05:57:55] <XXCoder> once I get BOB working and configured I can simply connect and test.
[06:00:33] <jthornton> I have to transplant my basil this morning they are trying to cover each other up lol
[06:01:24] <XXCoder> heh
[06:01:34] <XXCoder> I am reminded of gandi quote
[06:01:47] <XXCoder> he was asked wether peace was like plants
[06:01:55] <XXCoder> he said no, because plants are in constant battle
[06:02:00] <XXCoder> which is true
[06:26:36] <XXCoder> well cant find the quote
[07:23:01] * jthornton tries out bluefish
[07:23:12] <malcom2073> onefish twofish
[07:56:28] <XXCoder> heh
[07:56:43] <XXCoder> once wrote ecryption code for one of classes
[07:56:45] <XXCoder> fun.
[08:17:34] <malcom2073> XXCoder: I keep forgetting what channel I'm in. I try not to talk in reprap heh, too many people just looking for an argument.
[08:18:02] <XXCoder> trolls all way dow
[08:18:16] <jthornton> lol
[08:20:06] <malcom2073> "They're coming out of the walls!"
[08:21:28] <archivist> technology over optimism
[08:50:50] <MacPhone> morning
[08:57:40] <malcom2073> Morning
[09:02:48] <jthornton> morning
[09:03:38] <MacPhone> malcom2073 what were you turning on the lathe?
[09:04:20] <MacPhone> jthornton how is the elderberry wine coming along?
[09:05:51] <malcom2073> MacPhone: Some steel rod for work. We don't have a lathe at work so I volunteered to do it so I could get more practice
[09:06:04] <malcom2073> Just had to take like two tenths of an inch off of it
[09:06:44] <MacPhone> you are the nicest
[09:07:31] <MacPhone> wonder what this needs to be road worthy https://fayar.craigslist.org/cto/5981152556.html
[09:08:05] <malcom2073> Probably a new engine
[09:08:24] <MacPhone> yeah. thats the first thing that came to mind...
[09:09:30] <MacPhone> i talked to a guy about work on friday. I should be starting in the next 2 weeks. It's on location.
[09:10:11] <malcom2073> Oh nice
[09:10:17] <malcom2073> you having to provide your own work truck?
[09:11:02] <MacPhone> yeah. they provide a trailer. 30 days on 14 off
[09:11:21] <MacPhone> but still need to have all my gear
[09:11:47] <malcom2073> heh
[09:12:54] <MacPhone> it sounds like a good gig so i feel live some prayers have been answeref
[09:19:46] <archivist> too much spare time https://www.thevintagenews.com/2016/06/26/very-clever-removes-the-growth-rings-to-reveal-the-original-sapling/
[09:24:58] <malcom2073> That's pretty cool though
[09:25:06] <malcom2073> Most "artists" have too much spare time
[09:25:08] <malcom2073> :-p
[09:28:39] <MacPhone> heh
[09:29:10] <MacPhone> cool idea. would like to see him give a go at petrified wood
09:39 AM Tom_L: JT-Shop
09:40 AM jthornton: down here
09:40 AM jthornton: racking wine
09:41 AM Tom_L: it's official
09:41 AM jthornton: sweet
09:41 AM jthornton: did you convert any of the older files?
09:41 AM Tom_L: no
09:42 AM Tom_L: i could do 2016 forward
09:42 AM jthornton: yea that makes sense
09:43 AM Tom_L: i can do that anytime though
09:44 AM jthornton: yea
09:44 AM Tom_L: just had a minute this morning to sort out the indexes
09:44 AM Tom_L: still took a while even on the 2nd server
09:45 AM jthornton: wonder what the SG is
09:45 AM Tom_L: SG?
09:46 AM jthornton: Specific Gravity
09:46 AM jthornton: I'm hoping for 0.990
09:46 AM jthornton: fresh water is 1
09:47 AM Tom_L: wine making?
09:48 AM Tom_L: i don't remember what i did to fix the bot joining on startup. now if it crashes the old bot will restart
09:48 AM Tom_L: need to fix that
10:02 AM jthornton: yea have a batch of elderberry and elderberry blush
10:02 AM jthornton: came out 0.994 I'm happy with that
10:49 AM gos: heello.
11:35 AM gos: hello ???
11:36 AM pfred1: hi
11:37 AM gos: hi, how are you ?
11:37 AM pfred1: ok
11:38 AM gos: i am wondering if there is anything i can do to trick my computer into thinking it has a parallel port when it doesn't ? i am trying to work out some GUI stuff but linuxcnc won't run when it finds out there's no actual port.
11:41 AM JT-Shop: take a look at the sims
11:41 AM gos: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Build_A_Simulator_Manually
11:42 AM JT-Shop: not really just pick one from the menu
11:42 AM gos: oh.
11:42 AM JT-Shop: do you need the parallel port pins to show up to test with?
11:43 AM JT-Shop: that might not be possible without a parallel port
11:43 AM gos: well, i created a profile with the stepconfig and was hoping to get it to run.
11:43 AM gos: that would not be possible?
11:43 AM JT-Shop: check off sim at the start
11:44 AM gos: oh wow.
11:44 AM gos: haha alright! thank you.
11:45 AM JT-Shop: sometimes the hard part is knowing what the real question is :)
11:46 AM gos: yap.
11:49 AM * JT-Shop got that new product on line so time for a nap
11:56 AM * _methods fills out application to work for JT-Shop
12:34 PM IchGucksLive: hi
12:34 PM pfred1: hi
12:37 PM IchGucksLive: gos so what is the problem does it not start or only no function
12:37 PM IchGucksLive: The New Log has also a new TIMEzone
12:37 PM IchGucksLive: CST (GMT-6)
12:38 PM gos: oh, it was just saying how there was no parallel port and then would shut down. (there is no parallel port.. i'm not on the working computer.) but i wanted to try out the GUI still.
12:38 PM gos: turns out there is an option to allow simulation mode when creating the profile, so i remade the profile and it was all good.
12:39 PM IchGucksLive: for only gcode observing try the SAMPLE SIM Mashines
12:39 PM IchGucksLive: gos: https://youtu.be/ANSRDQeWkMA
12:40 PM gos: i actually did get linuxcnc to run before. i installed a bunch of things and ran axis. but now i'm doing John's custom GUI tutorial which went into that.
12:40 PM IchGucksLive: there are modern looks preset
12:41 PM IchGucksLive: try gemocappy
12:42 PM IchGucksLive: gos: you do not need to do your own setup on most just use the ready made
12:42 PM gos: well the purpose of doing John's custom GUI tutorial was so that i could learn a few things to be able to add buttons to control an Arduino .
12:42 PM pfred1: I use camotics to sim g code on my not LinuxCNC PC
12:43 PM IchGucksLive: pfred1: it also runs in linux
12:43 PM pfred1: IchGucksLive camotics?
12:43 PM IchGucksLive: yes
12:43 PM pfred1: yes
12:44 PM pfred1: http://camotics.org/manual.html#overview
12:45 PM pfred1: dealing with G Code on my development PC was an issue I encountered
12:46 PM pfred1: camotics ain't great but it serves the purpose of at least seeing what files may be
12:46 PM IchGucksLive: pfred1: https://youtu.be/oet39MVTCJc
12:46 PM BenL: I'm a n00b with linuxcnc, in the process of adapting a lathe with a friend of mine - I was wondering if we could use a stepper for the spindle, rather than a PWM based motor?
12:46 PM gos: IchGucksLive : would you know how to go about maybe customizing (adding a few buttons + python code) one of the ready made setups ? maybe gscreen or gmoccapy ?
12:47 PM IchGucksLive: pfred1: 5:40
12:47 PM IchGucksLive: BenL: Not a Good idee
12:48 PM BenL: IchGucksLive: oh? why so?
12:48 PM IchGucksLive: BenL: use a standard 1KW 1440U
12:48 PM pcw_home: BenL: you can but step motors are ~200W max so its got to be a tiny lathe
12:48 PM IchGucksLive: and a VFD at 80USD
12:48 PM BenL: its only a tiny lather :-)
12:48 PM pcw_mesa_ is now known as pcw_mesa
12:48 PM BenL: err
12:48 PM BenL: lathe
12:49 PM BenL: ok, so if we do that, can we config linuxcnc so it knows what's going on and can cut threads?
12:49 PM IchGucksLive: gos: http://linuxcnc.org/docs/2.6/html/common/python-interface.html
12:50 PM IchGucksLive: BenL: you need at least a encoder
12:50 PM IchGucksLive: lets say 100 min
12:51 PM BenL: IchGucksLive: can't assume that it just doesn't miss steps?
12:51 PM pcw_home: you could probably get by with just an index sensor
12:51 PM IchGucksLive: no for the spindlle
12:53 PM pcw_home: with a parallel port config you could get the encoder signal from the step signal in hal
12:53 PM pcw_home: though you still need an index sensor
12:54 PM IchGucksLive: pcw_home: seen people working with 2 parports to get a full control closed stepper
12:54 PM IchGucksLive: 3parports !
12:55 PM pcw_home: Yeah you can do that but the max encoder res*RPM will be small
12:55 PM BenL: hmm, thanks for the info, will ponder further
12:55 PM nallar is now known as Ross
12:59 PM pcw_home: why are you not using the original motor?
01:08 PM IchGucksLive: so one month to go for the 12.04 will run out
01:08 PM IchGucksLive: will we loos also the complete repro as on 10.04 runoff
01:30 PM * JT-Shop got the store front updated so time for some fun stuff
01:44 PM IchGucksLive: Gn8
01:56 PM malcom2073: Wolf_: https://sites.google.com/site/technoswapfest2/
02:05 PM Wolf_: cool, always when I’m broke lol
02:09 PM Loetmichel_: Wolf_: tell me about it... i am contemplating to buy an used 1998 BMW 528i... the car is cheap, 850€... but the insurance and tax will be more than the buying price... ;)
02:10 PM Loetmichel_: and will be bordering the amount of money i am willing to spend for a toy ;)
02:10 PM Loetmichel_: more than TWICE the buying price... anually... ;)
02:11 PM Loetmichel_: decisions, decisions ;)
02:12 PM Loetmichel_: (on the plus side: it has a trailer hitch, so i can buy big machines and carry them to me ;)
02:15 PM Wolf_: I should sell off some of my RC gear
02:47 PM JT-Shop: what do you have?
02:47 PM Wolf_: dx18qq w/ rx
02:50 PM gos: maybe you can get one way insurance on the car ?
02:56 PM JT-Shop: I need one with flaparon, crow and free mixing
02:57 PM Tom_L: still had the wrong ip
02:57 PM JT-Shop: me?
02:57 PM Tom_L: me
02:57 PM Tom_L: was pointing to the test server still
02:58 PM Wolf_: JT-Shop: I use a taranis for most of my stuff, mixer is totally open
02:58 PM JT-Shop: ah
02:59 PM JT-Shop: it's been so long since I've flown my last radio was a JR PCM10 and a JR PCM10H
03:00 PM Kevin`: kyle___: the cheapest ones are brushed dc, and need an external sensor for speed control. the slightly less cheap but still cheap ones are ac induction
03:00 PM Kevin`: oops, scrollback
03:01 PM Kevin`: JT-Shop: get a radio that uses opentx.. any mix you can think of is possible
03:01 PM JT-Shop: thanks
03:02 PM Kevin`: JT-Shop: eg http://alofthobbies.com/frsky-taranis-plus-transmitter-with-travel-case.html
03:02 PM Kevin`: fairly popular so good infos out there
03:03 PM JT-Shop: good price too
03:03 PM JT-Shop: out of stock there
03:03 PM Tom_L: so you're able to set your own frequencies now?
03:03 PM Tom_L: what bands?
03:04 PM Wolf_: unless you really want a spektrum tx with a 18ch rx that runs 4 sat rx, only $750
03:04 PM JT-Shop: no more freq pins lol
03:05 PM Tom_L: i've been away from that far too long
03:05 PM Kevin`: Tom_L: that radio is fixed frequency 2.4ghz. although it has a module slot for arbitrary radios, of which vhf sorts are popular for long distance telemetry
03:05 PM Wolf_: spektrum and stock taranis are both 2.4ghz but different protocols
03:05 PM Wolf_: my taranis has a 1w 433mhz tx module in it
03:05 PM Tom_L: so they don't use the old air/ground frequencies anymore?
03:05 PM Wolf_: nope
03:06 PM Tom_L: were those reallocated?
03:06 PM Kevin`: that's a shame really, as the old channels are perfect for what they do
03:06 PM Kevin`: just needs a modern digital protocol run on them :(
03:06 PM Wolf_: still in use I think
03:06 PM Kevin`: you can still use them
03:06 PM Tom_L: i don't even remember what they were now.. 27 & 49 iirc
03:07 PM JT-Shop: 72
03:07 PM Tom_L: yeah
03:07 PM Wolf_: https://www.dropbox.com/s/2rhhhe4ap6x81mu/Photo%20Mar%2007%2C%2011%2054%2009%20AM.jpg?dl=0 lol
03:07 PM Tom_L: i forgot what the ham band was too
03:07 PM Tom_L: the ham guys had one they could use with a license
03:08 PM Kevin`: there's a lot of bands you can use with a ham license
03:08 PM Wolf_: old school vs new
03:09 PM Tom_L: i recall the one on the right
03:09 PM Tom_L: the one i recall wasn't a wheel radio though
03:09 PM JT-Shop: me and a buddy designed a plane to do slow tight maneuvers and this is the modern electric version http://gnipsel.com/images/rc-planes/Trike-It-e01.jpg
03:09 PM JT-Shop: he just finished his a week ago
03:10 PM Tom_L: i was at a place a while back a bunch of guys were flying small ones indoors
03:10 PM Tom_L: in a gym
03:12 PM JT-Shop: I have one small enough to fly in a gym
03:14 PM JT-Shop: https://twistedhobbys.com/th-32-epp-edge-540-gh-w-hd-landing-gear/
03:15 PM Wolf_: I don’t have many slow things lol
03:15 PM Kevin`: twisted hobbies makes great planes
03:16 PM JT-Shop: https://www.amainhobbies.com/frsky-2.4ghz-accst-taranis-x9d-plus-telemetry-transmitter-w-x8r-receiver-case-frkx9dplus-case/p450171?gclid=CN3vt-22i9ICFQK2wAodDGMBIw
03:17 PM JT-Shop: amain has one hmmm
03:17 PM JT-Shop: what does the telementry do?
03:17 PM JT-Shop: hell they are out of stock too
03:19 PM Wolf_: the regular rx will give a rssi (signal strength) servo rail voltage, A2 3v voltage divider input and optional I think gps and other stuff
03:19 PM JT-Shop: 64 mixers 9 flight modes hmm I think that will cover my needs lol
03:19 PM JT-Shop: neat
03:20 PM Wolf_: http://i.imgur.com/lVFjOzA.jpg =)
03:21 PM JT-Shop: need a tube of welders?
03:21 PM Wolf_: goop worked well on it http://i.imgur.com/Lxc1peM.jpg
03:21 PM JT-Shop: I used to have an air force of 1/4 and 1/3 scale planes gliders helicopters etc
03:22 PM Tom_L: you fly helicopters too?
03:22 PM Tom_L: i think those are cool
03:22 PM SpeedEvil: 1/3 scale...
03:22 PM JT-Shop: I used to be a field rep for Xcell
03:22 PM Tom_L: seen what some guys around here can do
03:22 PM JT-Shop: a few 1/3 scale planes
03:23 PM Wolf_: I fly it all, I suck on the RC helis tho
03:23 PM Tom_L: used to boat race
03:23 PM Tom_L: collected a box full of trophies, got tired of all the bickering and got out of it
03:23 PM Wolf_: boats I haven’t messed with
03:24 PM JT-Shop: yea some of the politics at the air fields was a PIA
03:24 PM Tom_L: was alot of fun
03:24 PM Wolf_: rc crawlers are fun tho http://i.imgur.com/VbgciJh.jpg
03:24 PM JT-Shop: Wolf_: is trying to use up all my bandwidth lol
03:24 PM Wolf_: yup
03:28 PM gos: hey guys, i'm trying to understand a python code and i'm not really sure how the language is working.
03:28 PM gos: for the following code
03:28 PM gos: def periodic(self): self.status.poll()
03:28 PM JT-Shop: paste.ubuntu.com
03:28 PM gos: oh. that's handy.
03:28 PM pfred1: thre's probably a python channel on this network
03:29 PM gos: http://paste.ubuntu.com/23984321/
03:29 PM gos: for the poll methods, where is he getting them from .. a library?
03:29 PM JT-Shop: actually the python is about linuxcnc
03:30 PM JT-Shop: it comes from linuxcnc
03:31 PM gos: is the "def periodic(self)" from linuxcnc also or is it defined right at that line /
03:31 PM JT-Shop: def is a python term which means define this function named periodic
03:31 PM JT-Shop: self means it is called with self.periodic
03:32 PM gos: right, i read that it's similar to a class.
03:33 PM JT-Shop: not really a function can't be used to create another function
03:33 PM gos: oh .
03:33 PM JT-Shop: in this case the function is part of the gui3 class
03:33 PM JT-Shop: I see your having fun with my tutorials :)
03:33 PM gos: ohhh. yeah i forgot about that.
03:33 PM gos: oh haha you're the author ?
03:34 PM JT-Shop: aye
03:34 PM JT-Shop: that's my web site
03:34 PM gos: oh wow, it feels like i'm meeting an idol right now.
03:34 PM gos: haha yeah. i have been running through the tutorials for the last few days
03:35 PM gos: so but, if periodic is a function you created, how is it periodic can use "status.poll()" ?
03:36 PM Deejay: gn8
03:38 PM JT-Shop: http://linuxcnc.org/docs/2.7/html/config/python-interface.html#_reading_linuxcnc_status
03:39 PM JT-Shop: self.status = self.emc.stat()
03:39 PM JT-Shop: that line in the init creates self.status from self.emc.stat()
03:39 PM Roguish: hey JT-Shop, while you
03:39 PM JT-Shop: waddup
03:40 PM Roguish: while you're on python. have a question/problem
03:40 PM * JT-Shop runs and hides
03:40 PM Roguish: I'm setting up a simple vismach for my bp
03:40 PM Roguish: in some of the examples, there is simple math in the main python script.
03:41 PM Roguish: when I try even 1 simple expression like an add or subrtract, it doesn't run
03:42 PM JT-Shop: paste.ubuntu.com the lines
03:42 PM Roguish: ok, will get it in a quick minute.
03:52 PM Roguish_desk: JT-Shop daggonit. now it works.
03:53 PM Roguish_desk: can't explain anything now.
03:54 PM Roguish_desk: hey, what image bin place is good these days?
03:55 PM pfred1: I use imgur
03:58 PM JT-Shop: imagebin.ca
03:58 PM Roguish_desk: JT-Shop: check it out. Bridgeport with tool that changes based on tool table lengths and diameters.
03:59 PM Roguish_desk: http://imgur.com/a/GzxH8
04:00 PM JT-Shop: if you use imagebin.ca and post the direct link like this https://ibin.co/3CBDI4leF8rZ.jpg you don't get the ads
04:01 PM * JT-Shop goes back to looking for the missing Spectre 3996
04:03 PM Roguish_desk: https://imagebin.ca/v/3CBEE9GYSUYE
04:04 PM Roguish_desk: thanks all.
04:06 PM JT-Shop: looks good, there are 2 choices the direct link is the second one
04:06 PM JT-Shop: like this Direct image link: https://ibin.co/3CBDI4leF8rZ.jpg
04:24 PM Roguish_desk: JT-Shop, yeah, got that one. now i'm looking at screen recorders.
04:24 PM JT-Shop: let me wander down to the beer cave and I'll get the name of the one I use
04:25 PM JT-Shop: I tried a bunch of them recently
04:33 PM Tom_L: http://hackerspace.kinja.com/screen-recording-in-linux-1686055808
04:37 PM Tom_L: http://www.tecmint.com/best-linux-screen-recorders-for-desktop-screen-recording/
04:49 PM JT-Shop: Roguish_desk: Simple Screen Recorder and Gaupol subtitle editor
04:51 PM JT-Shop: a bad example lol https://www.youtube.com/watch?v=FPwz8pbZlpc
04:58 PM gos: is a home switch necessary to homing ?
04:58 PM cradek: no
04:58 PM pfred1: all you got to do to home is hit the button that saya HOME
04:59 PM cradek: you can home with index only or nothing at all, just locating the axis by eyeball
04:59 PM cradek: some sharpie marks
04:59 PM gos: that was originally what i was going to do.
04:59 PM JT-Shop: or match marks or hard stops
04:59 PM pfred1: I used a ballpoint pen
05:00 PM gos: but i'm reading homing configurations, and it looks like they're doing with switches
05:00 PM gos: http://linuxcnc.org/docs/html/config/ini-homing.html#_homing_sequence
05:00 PM pfred1: but getitng the machine back there is a hassle so I just go z0 y0 z0 before i shut down
05:00 PM pfred1: x0
05:01 PM pfred1: I just pick the command in MDI history it saves on typos
05:01 PM JT-Shop: I have a button on my plasma "Rapid to Home"
05:01 PM JT-Shop: and I have home switches
05:01 PM pfred1: snitches get switches
05:04 PM MacGalempsy: thought I was going to have a week, but they called this morning and want me on location tomorrow AM
05:20 PM JT-Shop: hi ho... hi ho... it's off to work you go
05:21 PM MacGalempsy: well its a good thing
05:21 PM MacGalempsy: its only been 14 months
05:21 PM MacGalempsy: actually 17 months
05:31 PM gos: mmm. i think i have been running linuxcnc from a simulator . (followed these instructions here : http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Build_A_Simulator_Manually)
05:33 PM gos: i'd like to get started on modifying the gscreen gui. would you guys know where linuxcnc is installed i am running the linux installed from the linuxcnc bootable ?
05:33 PM JT-Shop: download a RIP and modify that
05:34 PM JT-Shop: git clone git://git.linuxcnc.org/git/linuxcnc.git lcnc
05:35 PM JT-Shop: run that in a terminal to create a clone of LinuxCNC in the lcnc directory
05:35 PM JT-Shop: you can change the name to anything
05:35 PM JT-Shop: oh and do cd lcnc then git checkout 2.7
05:38 PM JT-Shop: gos: where are you located?
05:39 PM gos: uhh i just did git checkout 2.7
05:40 PM gos: is this what's called a RIP?
05:40 PM JT-Shop: RIP = Run In Place you must clone first
05:41 PM gos: but i just did clone right?
05:41 PM XXCoder: attack of the clones
05:42 PM JT-Shop: dunno what you did
05:42 PM gos: i ran the git clone git://git.linuxcnc.org/git/linuxcnc.git lcnc
05:42 PM JT-Shop: yep you just cloned, now change to that directory
05:42 PM JT-Shop: cd lcnc
05:43 PM Roguish: if you followed the instructions, you 'cloned' the source. now you get to compile and Run In Place (RIP)
05:43 PM JT-Shop: need to get him on the right branch first lol
05:43 PM gos: i also did git checkout 2.7
05:43 PM JT-Shop: Roguish: did you see my post about vid capture
05:43 PM gos: which does something with the branch? what does this mean checkout and branch?
05:44 PM JT-Shop: ok your on the 2.7 branch
05:44 PM Roguish: JT. yes. sure did.
05:44 PM Roguish: thansk
05:44 PM JT-Shop: now cd src
05:44 PM JT-Shop: ./autogen.sh
05:44 PM JT-Shop: ./configure --enable-build-documentation
05:44 PM JT-Shop: make
05:45 PM JT-Shop: sudo make setuid
05:45 PM JT-Shop: linuxcnc
05:45 PM JT-Shop: oh crap forgot a step
05:45 PM JT-Shop: after sudo make setuid do cd ..
05:45 PM JT-Shop: . ./scripts/rip-environment
05:45 PM JT-Shop: then linuxcnc
05:45 PM gos: kk
05:46 PM JT-Shop: gos: where from?
05:46 PM gos: oh sorry, when you said you where are you located, i thought you meant in the steps.
05:46 PM gos: I am from Canada.
05:46 PM JT-Shop: your neighbors to zeeshan then
05:46 PM gos: This is for a university school project actually.
05:47 PM JT-Shop: cool
05:47 PM gos: we have an ultrasonic welder horn
05:48 PM gos: the horn is hooked to the schools pressure supply and it'll actuate the horn down and weld composite materials.
05:48 PM JT-Shop: any python mods don't need to recompile just run again
05:49 PM gos: it's still in the make process right now. might take a while.
05:49 PM JT-Shop: yea that does take a bit
05:50 PM JT-Shop: the . ./scripts/rip-environment sets up the environment so when you run linuxcnc from that terminal you get the RIP
05:50 PM JT-Shop: otherwise you will get the installed version
05:51 PM gos: what would be the alternative to RIP ?
05:51 PM JT-Shop: build a deb and install it
05:52 PM JT-Shop: after all changes are made
05:52 PM JT-Shop: debian/configure -r ; debuild -uc -us
05:52 PM gos: so if it's run-in-place, it's not installed ?
05:52 PM JT-Shop: builds a rtai deb
05:52 PM JT-Shop: well yes and no
05:53 PM JT-Shop: it's installed but not on your path
05:53 PM JT-Shop: sudo dpkg -i packagename.deb will install the package
05:53 PM gos: what do you mean not on my path?
05:54 PM JT-Shop: programs in your user directory are not normally executables so not on the search path
05:55 PM JT-Shop: if you open a terminal and type linuxcnc
05:55 PM JT-Shop: you get the one that is installed in user/bin or some place like that
05:58 PM gos: i can't seem to run rip-environment by itself
05:58 PM gos: it says there's two ways to do it, am i supposed to write rip-environment linuxcnc ?
05:58 PM JT-Shop: did you cd ..
05:58 PM JT-Shop: . ./scripts/rip-environment
05:59 PM JT-Shop: note the dot space dot slash
05:59 PM gos: right now i'm in the scripts directory
05:59 PM JT-Shop: cd ..
05:59 PM gos: ohhhhh.
05:59 PM gos: that's funny.
06:00 PM JT-Shop: to run something not on your path you have to prepend it with ./ and in some cases . ./
06:01 PM gos: i'll have to read up on what a path is in linux, it sounds like it's just not just the directory location like in windows.
06:01 PM JT-Shop: open a terminal and type $PATH
06:02 PM Loetmichel: hmmm. Does anyone know an english word fot these "outdoor tiles"? -> http://media.shpock.com/waschbetonplatten-263aa5de.jpg
06:02 PM Loetmichel: for
06:02 PM JT-Shop: that will display your current "path"
06:02 PM XXCoder: step blocks? not too sure too
06:02 PM XXCoder: pathway blocks?
06:02 PM Loetmichel: its concrete made with river gravel (round) and then the top layer of concrete washed off
06:03 PM Loetmichel: i meant the surface of these pathway blocks specifically
06:03 PM XXCoder: oh
06:03 PM gos: so it is the same. but that doesn't make sense then, was the rip-environment not in the /scripts directory?
06:04 PM JT-Shop: yes it is but to run it you have to prepend it with . ./
06:04 PM JT-Shop: a lot of linux does not make sense at first
06:04 PM JT-Shop: part of the fun!
06:05 PM gos: could it be that the terminal can't be in the same directory
06:05 PM gos: as the rip-environment runs ?
06:05 PM Loetmichel: google has no idea what "waschbeton" would be in english it seems... do the americans/british dont have that stuff? is that a german thing?
06:05 PM JT-Shop: dunnno normally I'm in the lcnc dirctory when I run . ./scripts/rip-environment
06:05 PM gos: mmm okay
06:06 PM gos: ok so what now ? i'm looking to get the files to modify gscreen :o
06:07 PM JT-Shop: what you did was to build linuxcnc now look in src/emc/usr_intf/gscreen
06:08 PM JT-Shop: after modifications you will have to build again with make
06:08 PM JT-Shop: just to place the executables in /bin
06:08 PM gos: build the linuxcnc again?
06:08 PM JT-Shop: after you change gscreen
06:09 PM JT-Shop: look in /bin you will see gscreen with no .py
06:09 PM JT-Shop: that's what is run when you start your configuration
06:10 PM XXCoder: Loetmichel: there might be literally no english word for it
06:10 PM os1r1s: Loetmichel Pavers
06:10 PM gos: i see.
06:10 PM JT-Shop: farfrompooping?
06:11 PM os1r1s: Loetmichel Thats what they are called at HD/Lowes
06:11 PM gos: so when i RIP linuxcnc, the gscreen that opens is the one in bin
06:11 PM Loetmichel: os1r1s: with that surface?
06:11 PM os1r1s: Loetmichel It a general term for any of the concrete outdoor tiles
06:11 PM XXCoder: https://www.amazon.com/Solar-Clear-Glass-Brick-Paver/dp/B00DI9WY2W/ interesting
06:11 PM os1r1s: Loetmichel So even with that surface, they would be pavers
06:11 PM Loetmichel: i.E half protuding river gravel
06:12 PM JT-Shop: it's a washed finish
06:12 PM gregcnc: exposed aggregate
06:12 PM Loetmichel: i was aiming at the surface of it. its also found on big facade "tiles" sometimes
06:13 PM JT-Shop: say goodnight Gracie
06:13 PM gos: when i rebuild, is there a way to just rebuild the gscreen or does the entire linuxcnc have teo be rebuilt ?
06:13 PM Loetmichel: exposed aggregate would imho be close... i wonder if thats not that much used in the u.s or what?
06:13 PM gregcnc: that IS what is called here
06:13 PM XXCoder: its common
06:13 PM XXCoder: just no one word for it
06:14 PM Loetmichel: i see
06:14 PM Loetmichel: thanks
06:14 PM gregcnc: german has a way of combining 43 words into one
06:14 PM Loetmichel: yeah, tell me. i live in germany ;)
06:14 PM XXCoder: german scabble ;)
06:15 PM XXCoder: https://i.imgur.com/h3p3f4g.png
06:15 PM Loetmichel: "need a bigger board" is one of the thng you hear most in german scrabble sessions ;)
06:16 PM os1r1s: Loetmichel I think that surface is called "Pebbled concrete"
06:17 PM Loetmichel: Its a PITA to clean tho
06:17 PM Loetmichel: and "fun" in the winter when it starts to snow
06:18 PM os1r1s: Or also called "exposed aggregate concrete"
06:18 PM Loetmichel: because the round surface of the pebbles have next to no grip
06:18 PM os1r1s: Loetmichel I don't see it much here anymore, but I remember it as a child. I think the easiest way to clean is with a pressure washer. Though that would not be too effective in the winter
06:18 PM Loetmichel: right
06:19 PM Loetmichel: i have that stuff in the backyard.
06:19 PM Loetmichel: (rented flat)
06:19 PM os1r1s: Where in DE?
06:19 PM Loetmichel: fun stuff when you have a wife that walks on crutches
06:19 PM Loetmichel: pretty much in the middle
06:19 PM Loetmichel: (offenbach am main)
06:20 PM XXCoder: just yuse salt and hot water mixed in pressure washer in winter ;)
06:20 PM Loetmichel: also our drain on the backyard could do with a bit of declogging...
06:20 PM os1r1s: Loetmichel Near frankfurt. I have ben close to there
06:20 PM Loetmichel: https://www.youtube.com/watch?v=sm9e3_O7Qxc
06:21 PM Loetmichel: ... that happens on every hard rain here :-)
06:21 PM Loetmichel: os1r1s: jeah, less than 10 miles to the center of frankfurt
06:22 PM XXCoder: ugh autodocus'
06:22 PM Loetmichel: ?
06:23 PM XXCoder: *autofocus
06:23 PM Loetmichel: yeah
06:23 PM os1r1s: Loetmichel I have spent time in Dortmund, Frankfurt, Stuttgart, and Munich on business. But very little time away from city centers.
06:23 PM Loetmichel: to say it with AoE: "Focus, bitch!"
07:17 PM pfred1: focus you fawk!
07:21 PM san_51pc_ is now known as san_51pc
07:53 PM kyle___: so, has anyone tried epoxy granite here?
07:54 PM XXCoder: welcome back
07:55 PM kyle___: hello
07:55 PM kyle___: not the best one
07:55 PM kyle___: oops wrong chat window
07:56 PM XXCoder: lol
08:07 PM kyle___: maybe I can find an old used straight-edge and flatten it out and cast it in to mount my rails to
08:53 PM kyle___: http://www.ebay.com/itm/New-24-iGaging-Premium-Precision-Hardened-Steel-Straight-Edge-with-Beveled-Edge-/140996934930
08:53 PM kyle___: hah! it's perfectly stupid
08:53 PM kyle___: within 1.5 thou over 24"
08:54 PM BeachBumPete: http://i.imgur.com/7jyh9GT.jpg This stupid spot is driving me crazy LOL
09:07 PM XXCoder: BeachBumPete: hide it in bigger spot!
09:07 PM Wolf_: time to break out the dremel stock wrecker
09:09 PM pfred1: kyle___ that's more accurate than cold rolled bar stock but it is hardened so a bit harder to work with
09:09 PM BeachBumPete: naah I will get it sorted. The real issue is that there are several slots and thicknesses coming together right there as well as the undercut on the ends of that radiused corner
09:13 PM kyle___: maybe I could ask him to drill holes in one for me, pfred1
09:14 PM pfred1: maybe
09:14 PM kyle___: the guy is from Missouri so maybe I could strike up some camaraderie
09:15 PM kyle___: maybe I could manage it with my drill press and a carbide drill bit though?
09:15 PM pfred1: actually this ground flat stock is more accurate but more expensive http://www.speedymetals.com/pc-4354-8215-316-x-1-12-low-carbon-grnd-flat.aspx
09:16 PM kyle___: hm
09:16 PM pfred1: just cold rolled is a lot cheaper
09:16 PM kyle___: easier to work with, price is pretty much the same if shipping is reasonable here
09:16 PM pfred1: like a quarter the price
09:17 PM kyle___: could buy a cheap-ish surface plate and go at it...
09:17 PM kyle___: always wanted to learn how to scrape
09:17 PM pfred1: well the stock is probably better but they have to worse case it
09:18 PM roycroft: cold rolled steel is a pain in the butt to work with
09:18 PM roycroft: i avoid it whenever possible
09:18 PM roycroft: unless i'm not going to have to machine it
09:18 PM pfred1: roycroft what is so bad about it?
09:18 PM roycroft: it gets somewhat case hardened from the rolling process
09:18 PM pfred1: that's all we used in the shop I worked in
09:18 PM roycroft: and the rolling process also stresses the metal
09:19 PM kyle___: well, all I have to do is drill holes and cast it into my epoxy granite
09:19 PM roycroft: most of the time it moves significantly when you start machining it
09:19 PM pfred1: hmmm
09:20 PM roycroft: and if you're going to machine it to square/flatten it back up you might as well just get hot rolled to begin with
09:20 PM pfred1: roycroft we would pocket the stuff right out didn't erally have a problem
09:21 PM pfred1: we made these http://i.imgur.com/Z5pXaMO.jpg
09:21 PM roycroft: cold rolled steel has a nicer mill finish than hot rolled, for sure
09:21 PM roycroft: and if you don't need to make precision parts, and won't be doing much besides drilling it or cutting it up it's fine
09:21 PM pfred1: those were like 20 foor long bars of cold rolled when we started
09:24 PM kyle___: hm, squareness is less of a concern, but flatness is important
09:24 PM kyle___: so that ground flat stuff seems like the best bet
09:25 PM pfred1: kyle___ the spec on that "straightedge" you found looks like a typo
09:26 PM pfred1: 0.0015 over 2 feet isn't exactly super precision really
09:26 PM kyle___: it's not
09:26 PM pfred1: not when ground stock specs better
09:26 PM kyle___: but I don't really know how to find precise stuff yet since I don't know what kind of stuff is precise!
09:26 PM kyle___: so I'm glad I have you guys
09:27 PM pfred1: add another zero and I'd be impressed
09:28 PM pfred1: I could probably flatten a bar of steel on a concrete floor by hand to a thou and a half
09:28 PM XXCoder: .0015"?
09:28 PM pfred1: yeah
09:29 PM kyle___: sounds like quite the floor
09:29 PM XXCoder: ok. I always forget what thou means :P
09:29 PM XXCoder: sad, for a machinist, I know.
09:29 PM pfred1: tenth is the confusing one
09:29 PM kyle___: seriously
09:29 PM pfred1: when machinists talk about tenths
09:29 PM kyle___: should be called a millionth
09:30 PM pfred1: they're talking about ten thousandths
09:30 PM kyle___: oops
09:30 PM kyle___: that just shows how confusing it is
09:30 PM pfred1: no one givea a flying about a tenth of an inch in a precision shop
09:31 PM pfred1: you'd better be able ot do better than that with a hacksaw
09:32 PM pfred1: who saw the latest AvE vid where he butchers a piece of round stock with a portaband?
09:32 PM pfred1: he missed that cut by more than a tenth of an inch
09:46 PM os1r1s: pfred1 Is that a g0704 you are curring on?
09:46 PM os1r1s: cuttin
09:46 PM pfred1: nope it is a scratch and dent HF special
09:46 PM os1r1s: pfred1 Ahh, k
09:46 PM pfred1: it is a mainland RF-32
09:46 PM pfred1: its OK
09:47 PM pfred1: same basic thing as a g0704 just not a Grizzly
09:47 PM os1r1s: The mounts looked pretty close to the same
09:47 PM os1r1s: Thats why I asked :)
09:47 PM ApocalypseCow is now known as insomnia
09:47 PM os1r1s: I have a PM25MV, which is also a derivative
09:49 PM pfred1: here's another picture of it http://i.imgur.com/rSWlk.jpg
11:04 PM XXCoder: more fun with paper https://www.youtube.com/watch?v=GiOrCSWymS0
11:10 PM kyle___: that's interestingly clean
11:11 PM XXCoder: yeah
11:14 PM pfred1: john heitz started all of this paper disc stuff with a table saw
