[00:00:45] <humble_sea_bass> attitude is often a lot more meaningful than skill level
[00:02:13] <humble_sea_bass> congrats though
[00:03:39] <XXCoder1> thanks. and indeed
[00:03:52] <XXCoder1> I really STINK on interviews though
[00:03:59] <XXCoder1> probably why I cant find job in my major
[00:05:15] <humble_sea_bass> interviews are squirly situations
[00:05:58] <humble_sea_bass> you eitherlike those kind of situations or you dont
[00:06:29] <humble_sea_bass> but like I said, attitude shines through if you have a receptive interviewer
[00:07:01] <XXCoder1> funny thing I think I usually do interviews well
[00:07:05] <XXCoder1> I just dont get jobs
[00:07:57] <humble_sea_bass> people don't say it out loud, but i bet disability has a lot to do with it
[00:08:21] <XXCoder1> some majors is fine, but CS and IT probably. unno
[00:08:23] <XXCoder1> dunno
[00:18:10] <XXCoder1> anyway
[00:18:16] <XXCoder1> glad I'm doing pretty good
[00:20:06] <FrankZappa> hey yay
[00:20:09] <FrankZappa> hi
[00:20:14] <FrankZappa> I'm drunk and stoned
[00:20:19] <FrankZappa> I love making things
[00:20:24] <FrankZappa> Im doing 3d shit
[00:20:28] <XXCoder1> uppers downers sideways
[00:20:41] <FrankZappa> hope you are makin yourself happy in your life :)
[00:20:53] <XXCoder1> thanks
[00:21:33] <FrankZappa> shit sorry
[00:21:46] <FrankZappa> I just noticed I made a grand in a day on my investments
[00:21:50] <FrankZappa> sh
[00:22:05] <FrankZappa> sluggin grey goose to celebrate
[00:22:23] <humble_sea_bass> p low brow
[00:22:41] <FrankZappa> this sea bass
[00:22:49] <FrankZappa> is the zen source
[00:23:04] <humble_sea_bass> yeah. my real name is Yolo Ono
[00:23:14] <FrankZappa> like a mountain waterfall, surrounded by ferns, blowing rainbows across the noonday sun's rays

[00:30:55] <XXCoder1> damn'
[00:30:58] <XXCoder1> your lawyer is good
[00:31:03] <XXCoder1> pic is gone already lol

[00:52:20] <humble_sea_bass> omfg this Senna documentary is fucking tits
[00:52:31] <humble_sea_bass> how coulcd I let 4 years go by without seeing it
[02:37:51] <markhausen> Speaks anyone german ?
[02:40:58] <Deejay__> moin
[02:44:40] <markhausen> Hallo können Sie mir weiterhelfen ? Ich habe ein problem mit einem TB6560 controller
[03:17:16] <zeeshan> http://i.imgur.com/9FpwxME.png
[03:17:32] <zeeshan> anyone know what kind of error causes this: http://i.imgur.com/9FpwxME.png
[03:20:12] <Einar1> It could be stiction. You command a move, but the ballscrew, mounts etc. just build up some tension. Then as it gets high enough the slide does just that. And it all starts over again.
[03:21:45] <zeeshan> hm
[03:23:39] <Einar1> Is this a lathe, mill or ... Does it have ball rails (which have almost no stiction).
[03:23:45] <zeeshan> lathe
[03:23:46] <zeeshan> ball screws
[03:24:13] <Einar1> Yes, but the slides? I assume cast iron on a lathe?
[03:24:24] <zeeshan> yea, ground and hardened
[03:24:27] <zeeshan> w/ way lube on em
[03:24:35] <zeeshan> its not sticking when i move it manually
[03:25:48] <Einar1> Cast iron slides do have stiction. Always! Try to thump the slide with a rubber mallet at 90 degrees to the motion before making each measurement.
[03:26:18] <Einar1> And I wrote thump, not smack!
[03:27:03] <zeeshan> haha
[03:28:59] <Einar1> If the ball screw is long and small diameter it will have som flex. But usually it is in the bearings and the mounts. They need to be beefy not to flex. Pictures?
[03:30:00] <zeeshan> http://i.imgur.com/B495MXT.jpg
[03:30:05] <zeeshan> thats the best pic i have of em =D
[03:32:13] <Einar1> Uhhh... holding it in your hand a bit of flex is to be expected. ;-)
[03:32:30] <zeeshan> haha thats an old pic
[03:32:40] <zeeshan> http://i.imgur.com/cSJSvRY.jpg
[03:32:44] <zeeshan> thats the stepper in question
[03:32:51] <zeeshan> note i have a solid coupler now on it, not flexible
[03:32:58] <zeeshan> its 25mm dia ball screw
[03:35:56] <Einar1> The bearing mount looks rigid enough. The motor mount on the other hand is not rigid at all! What the torque stiffness is I can't guess at. But do expect some nasty resonances.
[03:36:32] <Einar1> A 25mm screw at 1m (?) lenght is plenty stiff.
[03:37:00] <zeeshan> 1.1 m
[03:37:50] <Einar1> Do you have a picture of the ball nut and how it's connected to the apron?
[03:39:54] <zeeshan> http://imgur.com/a/aRSsI
[03:41:29] <zeeshan> i had to mount it like that because there is a stationary ball screw cover
[03:42:45] <Einar1> That's going to give you some flex. It all adds up. But you have what? About 0.05mm? I would not expect it to be that much. Try what I said: to thump it before measure.
[03:43:06] <zeeshan> the thing is
[03:43:10] <zeeshan> flex usually flexes
[03:43:21] <zeeshan> like i'd see it flex on the dial indicator, and then return to a static value
[03:43:24] <zeeshan> it doesn't do that
[03:43:29] <Einar1> The thump will unstick the slide and release the tension so you get closer to where the ballscrew "tells it to be".
[03:43:56] <zeeshan> ill try the thump tomorrow :D
[03:44:00] <zeeshan> its 4:30 am here! im tired :D
[03:44:16] <zeeshan> thump in the direction of travel right
[03:44:31] <zeeshan> to help overcome the stiction
[03:45:14] <Einar1> Nono! Perpendicular to the movement. You do not want the thump to influence the position, just to release the stiction.
[03:45:21] <zeeshan> ah okay
[03:45:42] <zeeshan> will do :D
[03:45:57] <zeeshan> thank you
[03:45:58] <Einar1> In this case in the direction of the cross slide.
[03:46:17] <zeeshan> i'm gonan sleep before i pass out on the keyboard :D
[03:46:38] <Einar1> G'night. Here it's 10:30 in the morning.
[03:52:12] <archivist> zeeshan, that looks cyclic error
[03:56:54] <archivist> zeeshan, and increase the resolution (number of measured points) you may be seeing aliasing
[04:13:22] <Einar1> Or make several passes of measurements. If stiction the cycles will not coincide. If it's the screw, bearing or motor, the errors will always be at the same places.
[04:14:52] <Einar1> On the Y of my mill the end bearing block is not stiff enough, and I have errors that looks quite cyclic if doing just one measuring pass. Reminds me I really should fix it.
[04:29:00] <archivist> on mine one gets to the stepper resolution as the limiting factor http://www.archivist.info/cnc/screw_error/
[05:46:39] <zq_> zultron: hi there. i have a few patches to submit. is github/machinekit the official repository where i could issue a pull request, or is there someplace else more appropriate?
[07:48:23] <Jymmm> alex_joni: My new mini cnc lathe... http://www.amazon.com/Sanven-Metal-Motorized-Machine-Quality/dp/B00H2BV5MM/ref=sr_1_12?s=hi&ie=UTF8&qid=1400934433&sr=1-12
[07:52:43] <archivist> what a terrible advert
[07:53:06] <Jymmm> but but but it's CNC, right?
[07:53:13] <archivist> no
[07:53:29] <Jymmm> what you mean, it SAYS cnc, so it must be CNC ;)
[07:53:43] <archivist> even tells you later in the ad that it is not cnc
[07:55:13] <archivist> Important Note:
[07:55:13] <archivist> There are many customers reflecting it is not the CNC product. This is not the so-called industry CNC product.It can not be computer controlled. It is mainly used for teaching, hobbies and other DIY works.
[07:55:13] <Jymmm> lmao "This is not the so-called industry CNC product." I didn't even bother to read
[07:55:47] <archivist> look at the maths on Input voltage / Current / Power: 12VDC / 2A / 6W
[07:57:21] <Jymmm> sorry archivist, I was being sarcastic. Just thought it was such a riot that they tried to pass it off as a lathe much less a cnc controlled lathe. just buzzwords
[07:58:00] <archivist> over here that can be reported to the law
[07:58:40] <Jymmm> even with the disclaimer?
[07:59:24] <archivist> probably
[07:59:49] <archivist> we have the Advertising Standards Authority
[08:00:32] <archivist> I bet it fails the 20000 rpm spec too
[08:00:58] <Jymmm> That's without the belt installed =)
[08:15:18] <_methods> it's manual cnc
[08:15:47] <_methods> you're brain supplies the coordinates and your hands move it to the location
[08:15:58] <_methods> its a type of open loop cnc system lol
[08:16:20] <CaptHindsight> brain = computer, and you think about numbers or count as you turn the cranks
[08:16:21] <_methods> prone to error when i operate
[08:16:45] <_methods> see CaptHindsight gets it
[08:16:59] <_methods> he must have one of these "cnc's"
[08:17:05] <CaptHindsight> about as honest as unlimited internet
[08:19:38] <pcw_home> what do you mean open loop? Thats full vision system assisted closed loop motion
[08:19:51] <_methods> "my" system is open loop
[08:20:07] <_methods> brain isn't fully functional
[08:20:45] <_methods> at best
[08:21:15] <Jymmm> "we know"
[08:21:18] <_methods> or so my PLC (wife) controller tells me
[08:23:24] <Jymmm> _methods: PLC?! old skool... Replace her with a couple BeagleBone Blondes instead =)
[08:23:31] <CaptHindsight> is it even motorized? maybe the input voltage / Current / Power: 12VDC / 2A / 6W is just for the light
[08:23:39] <_methods> hahah
[08:23:59] <CaptHindsight> Item Weight 8.3 pounds
[08:24:35] <CaptHindsight> possibly aluminum and Styrofoam construction
[08:24:38] <Jymmm> That's with the brick PS
[08:26:26] <CaptHindsight> well the DIY 3d printer folk woud argue that it's a good design that works and isn't overbuilt just to pad the price
[08:26:46] <Jymmm> CaptHindsight: Nah, Prop 65 Warning... "This product *IS LEAD*..."
[08:27:11] <Jymmm> CaptHindsight: lol
[08:27:16] <CaptHindsight> possibly in the paint
[08:27:44] <Jymmm> CaptHindsight: lead is used as a plascitizer in the plastics
[08:28:53] <CaptHindsight> why not an injection molded and pultruded plastic lathe for plastic parts? this could set of a whole new wave of DIY madness
[08:29:30] <CaptHindsight> I should make one for indegogo
[08:29:58] <Jymmm> CaptHindsight: It can be done using glass impregnanted nylon, but the mold is liek $10,000
[08:30:39] <CaptHindsight> pultrusions for the linear guides and bearings
[08:30:57] <CaptHindsight> SLA/DLP for the rest
[08:31:16] <Jymmm> V-Groove bearings
[08:38:05] <_methods> man i think you've just hit on something
[08:38:09] <_methods> a playdoh lathe
[08:38:37] <CaptHindsight> a DIY pultruder
[08:38:55] <Jymmm> Well, I was thiing something more along the lines of a plastic 80.20 extrusion that you can cut to length on a table saw
[08:39:18] <_methods> playdoh and legos
[08:39:30] <_methods> the sky's the limit here
[08:39:40] <Jymmm> But enhanced so that you can also use it for linear bearings using like skatbaord bearings or some thng thing
[08:39:45] <CaptHindsight> yes, but that might not be DIY enough, but then again makerslide is popular
[08:39:55] <_methods> you guys better patent this quick
[08:40:17] <_methods> apparently the 3d people are patenting the lever
[08:40:40] <Jymmm> Let them adopt a lawyer
[08:40:42] <_methods> i hear they all have their panties in a bunch right now
[08:42:30] <CaptHindsight> Glassmaster used to make the fiberglass t-slot
[08:42:44] <_methods> i'm suprised the welding companies haven't stepped in to crush their nuts for this silliness
[08:42:46] <CaptHindsight> now it's made by Strongwell and Razor
[08:43:02] <_methods> they've been pushing "filament" for years
[08:44:45] <CaptHindsight> http://www.huntsman.com/polyurethanes/Media%20Library/global/files/practical%20guidelines%20for%20injection%20box%20design%20component%20metering%20equipment%20and%20processing.pdf
[08:46:13] <CaptHindsight> there a glue gun that uses pellets now but they haven't posted pics or video
[08:48:04] <CaptHindsight> it's easy enough to make, I'm just wondering what distance there is between the melt chamber and the nozzle tip
[08:48:42] <CaptHindsight> http://www.3ders.org/articles/20140518-sculptify-3d-printer-printing-directly-with-plastic-pellets-soon-on-kickstarter.html
[08:50:53] <CaptHindsight> http://products.uscosupply.com/Asset/Aickinstrut%20Strut%20System%20Brochure.pdf complete system of components
[09:15:03] <malcom2073> Wow, for the price of that "cnc" lathe on amazon, you can get a decent lathe at auction...
[09:15:15] <malcom2073> a muchlarger one at that
[09:16:40] <malcom2073> CaptHindsight: There is a 100% 3d printed lathe somewhere around.... another thingiverse special.
[09:17:00] <CaptHindsight> probably FDM
[09:17:14] <malcom2073> It is
[09:17:54] <Loetmichel> hmm
[09:18:06] <Loetmichel> a lathe made from PLA/abs?
[09:18:21] <Loetmichel> how rigid and precise can THAT be?
[09:18:35] <malcom2073> Loetmichel: i'll see if I can find the video, it's SCARY, and wobbly
[09:18:41] <CaptHindsight> doesn't have to be, look who buys them
[09:19:09] <kfoltman> next: hydraulic press made out of PLA
[09:19:37] <malcom2073> kfoltman: You jest, but I heard someone talking about a 3d printed air manifold, at 6 bar.... :/
[09:20:32] <CaptHindsight> but a v-grove and t-slot pultrusion might be easy enough for them to use
[09:21:00] <CaptHindsight> but I tend to overestimate peoples abilities
[09:21:25] <Loetmichel> malcom2073: thats not for the faint at heart, is it?
[09:28:24] <Tom_itx> still fighting network issues: http://paste.debian.net/101560/
[09:28:27] <Tom_itx> any thoughts?
[09:28:28] <CaptHindsight> it's unfortunate that 3d printing has become synonymous with FDM
[09:29:28] <CaptHindsight> my cutoff time is 1 hour with ubuntu breakage, if we can't fix ubuntu in under 1 hour we just reinstall
[09:30:20] <Tom_itx> oh, also tried live cd, hdd install, ssd install
[09:30:46] <CaptHindsight> they all break?
[09:30:58] <Tom_itx> live cd initially worked but a 2nd boot from it failed
[09:31:35] <Tom_itx> haven't tried it again this morning yet
[09:31:45] <CaptHindsight> what version 10.04?
[09:31:55] <Tom_itx> the live cd version
[09:32:44] <CaptHindsight> do sebs 3.4.55 RTAI kernel debs work with 10.04
[09:32:45] <_methods> man that is really weird
[09:32:47] <Tom_itx> 10.04 LTS
[09:33:13] <CaptHindsight> I wonder if it's ubuntu kernel issues with your hardware/bios combo
[09:33:15] <_methods> are those both onboard nics?
[09:33:29] <Tom_itx> one is the MB one is a card
[09:33:37] <Tom_itx> and both used to work just fine
[09:33:46] <_methods> well i'd trust an intel nic any day before realcrap
[09:34:00] <Tom_itx> well it isn't working either.
[09:34:07] <CaptHindsight> do they work with a fedora live cd?
[09:34:13] <Tom_itx> brb... puppy's gotta pee
[09:34:23] <Tom_itx> i don't have one currently
[09:34:36] <_methods> that's very strange
[09:34:41] <CaptHindsight> how has broken hardware been ruled out?
[09:34:45] <_methods> it hasn't
[09:35:19] <_methods> but it's weird that they connect then get drop
[09:35:28] <_methods> he says they don't stay connected long
[09:35:36] <CaptHindsight> but it's 2 nics that are acting up at the same time, both lose connection?
[09:35:42] <_methods> i wonder if his dhcp server is dc'n them
[09:35:46] <_methods> yeah
[09:36:08] <_methods> he tried diff routers though too
[09:36:13] <CaptHindsight> there are some nasty router/switch bugs also going around
[09:36:15] <_methods> man that's a good one
[09:36:22] <_methods> yeah that's why i use pfsense
[09:36:38] <_methods> i just use switches and AP's
[09:36:44] <CaptHindsight> we had 2 switches that would go nuts if we hooked them up in the DMZ
[09:37:13] <_methods> why you put the switch in the dmz?
[09:37:19] <_methods> that's kinda risky
[09:37:28] <CaptHindsight> yeah, for gaming
[09:37:33] <_methods> ah
[09:37:34] <CaptHindsight> lower latency
[09:38:18] <_methods> yeah i try not to expose any metal
[09:38:20] <CaptHindsight> or behind a firewall that ended up not being a firewall
[09:38:33] <CaptHindsight> like a modem for wimax :)
[09:39:07] <_methods> yeah i purchased my own modem i don't need any silliness on my modem
[09:39:15] <_methods> just give me a plain old modem
[09:39:16] <_methods> no wifi
[09:39:19] <_methods> no switch
[09:39:43] <_methods> no router
[09:40:02] <_methods> getting harder and harder to get that anymore though
[09:40:20] <CaptHindsight> just fiber right back to level3 :)
[09:40:32] <_methods> heheh
[09:40:58] <_methods> Tom_itx: if you connect one of those nics directly to the modem does it get dropped?
[09:41:14] <_methods> at least you could rule out some internal networking issues by doing that
[09:42:16] <_methods> if you can keep an ip connecting directly to the internet then you know the nic is fine and that pc's dhclient is correct
[09:42:30] <CaptHindsight> http://www.pbclinear.com/SIMO-Series-Components---GST maybe a low cost version of this for DIYers
[09:44:02] <_methods> Tom_itx: also make sure there is nothing on your network that has a conflicting ip address to whatever that box is grabbing
[09:44:44] <CaptHindsight> yes, test with just the PC and one nic connected at a time as well
[09:44:55] <_methods> ^^
[09:46:16] <CaptHindsight> ubuntu obfuscates by renaming, relocating and rewriting perfectly fine network managers and X
[09:47:42] <CaptHindsight> already done http://www.pbclinear.com/Download/ApplicationStory/Application-Story---Trinity-Labs-3D-Printing.pdf
[09:47:59] <archivist> I tend to set fixed IP in the network to get around any sillyness
[09:48:55] <CaptHindsight> yeah, that works well until you forget and have 2 machines on the same address :) not that I have ever done that
[09:50:00] <Tom_itx> _methods, i'll try that later on
[09:50:11] <Tom_itx> the modem is in the basement and the pc isn't
[09:50:33] <Tom_itx> i checked the ip addresses as well
[09:50:57] <Tom_itx> it does show the atom owning but it's not connected
[09:51:16] <archivist> I run a web and name server so fixed IP worksforme
[09:52:02] <Tom_itx> it's not a big issue, just frustrating
[09:53:01] <archivist> my test box 10.04 played me up a bit but setting fixed IP cured it
[09:53:17] <Tom_itx> i tried assigning a static ip too
[09:53:40] <archivist> dont forget the gateway and dns settings
[09:53:42] <Tom_itx> i could ping the router but not get past it
[09:53:44] <Tom_itx> i know
[09:54:09] <malcom2073> [10:11:30] <CaptHindsight> it's unfortunate that 3d printing has become synonymous with FDM
[09:54:19] <malcom2073> I think it's unfortunate that 3d printing has become synonymous with reprap
[09:54:48] <Tom_itx> that's what happens when minions take over the world
[09:56:24] <malcom2073> On the bright side, I have my 3d printer running linuxcnc on a beagleboneblack now, just did the first test and it worked great
[09:56:52] <XXCoder1> awesome
[09:57:30] <CaptHindsight> malcom2073: SLA, SLS inkjet? :)
[09:57:38] <malcom2073> CaptHindsight: nothing cool, just FDM
[09:57:57] <XXCoder1> fdm?
[09:58:10] <malcom2073> fused disposition
[09:58:14] <malcom2073> basically melted filament
[09:58:16] <CaptHindsight> FDM FFF GGG
[09:58:17] <malcom2073> (reprap)
[09:58:20] <XXCoder1> ahh ok
[09:58:26] <XXCoder1> "glue gun"
[09:58:30] <malcom2073> Ah yes
[09:58:32] <XXCoder1> someone here tend to call e that
[09:58:51] <malcom2073> The only printed part on my printer, is on the build plate though :) It's ballscew and linear rail based
[09:58:52] <CaptHindsight> fused deposition modeling, free forem fabrication , glorified glue gun
[09:59:26] <XXCoder1> I wouldnt mind having one though. I read on tricks how to make abs stuff smooth and shiny
[09:59:31] <XXCoder1> surpising simple
[09:59:35] <malcom2073> They have their uses
[10:00:15] <Tom_itx> ?
[10:00:21] <Tom_itx> making more repraps?
[10:00:30] <malcom2073> Tom_itx ugh. I use mine for one-off prototyping electronics enclosures and the like.
[10:00:34] <Tom_itx> i'd say 70% just do that
[10:00:41] <malcom2073> Tom_itx: likely more than 70% sadly
[10:00:50] <XXCoder1> yeah
[10:00:50] <_methods> http://www.thingiverse.com/thing:199786
[10:00:56] <_methods> that......
[10:00:56] <CaptHindsight> FDM + Fiber is great
[10:00:59] <Tom_itx> i started one and decided not to finish it
[10:01:00] <XXCoder1> mine wont be making any repraps
[10:01:15] <Tom_itx> didn't really have a end use for it
[10:01:31] <CaptHindsight> or FDM for resin and fillers, or concretes
[10:02:10] <malcom2073> Like I said, they have their uses, they're not for everyone. For me, I needed a lot of one-off enclosures, so it worked out ok
[10:02:28] <malcom2073> They're not really good for end-products
[10:02:33] <CaptHindsight> I'm working with epoxy and carbon fiber deposition to make carbon fiber parts with complex geometries
[10:03:09] <XXCoder1> new printer idea: epoxy-sand printer
[10:03:25] <CaptHindsight> sand + binder
[10:03:27] <XXCoder1> do it. if you get lots money bump some to me, enough for new car and printer
[10:03:37] <CaptHindsight> been done
[10:03:47] <XXCoder1> kickstart it anyway lol
[10:03:55] <CaptHindsight> low viscosity binder is inkjetted onto the sane
[10:03:59] <CaptHindsight> heh
[10:04:15] <CaptHindsight> water based epoxy
[10:04:43] <XXCoder1> isnt it mean water would dissolve that
[10:04:49] <CaptHindsight> that's one of my uses for the modified diesel fuel injectors
[10:05:09] <CaptHindsight> 30,000 psi at the tip
[10:05:32] <CaptHindsight> the water carries the epoxy
[10:05:34] <XXCoder1> well modifiction of idea then
[10:05:42] <XXCoder1> RGB printer
[10:05:44] <CaptHindsight> the water evaporates and then the epoxy cures
[10:05:58] <XXCoder1> 3 colors mixed to make certain color, just like inkjet and such
[10:06:13] <malcom2073> iirc, inkjet epoxy based stuff is patented
[10:06:20] <XXCoder1> so it would have colorspace similar with printer
[10:06:29] <malcom2073> anything spraying epoxy onto a powder
[10:06:29] <XXCoder1> black too actually lol
[10:06:37] <CaptHindsight> yeah so it's another Chinese special
[10:06:46] <CaptHindsight> actually CMYK+W
[10:06:58] <XXCoder1> w?
[10:07:03] <CaptHindsight> white
[10:07:10] <XXCoder1> ahh yea
[10:07:11] <CaptHindsight> so you can have light colors
[10:07:18] <XXCoder1> no paper to have white
[10:07:28] <CaptHindsight> BYOW
[10:07:35] <CaptHindsight> bring your own white
[10:07:40] <XXCoder1> yep lol
[10:07:48] <XXCoder1> talking about paper
[10:08:00] <XXCoder1> saw one printer that uses paper to make 3d stuff
[10:08:07] <XXCoder1> cuts stuff out of sheets in layers
[10:08:22] <CaptHindsight> it laminates the sheets
[10:08:24] <malcom2073> Hah I saw that
[10:08:41] <CaptHindsight> it can also be done with other substrates
[10:08:55] <XXCoder1> while I think that is cool I'm uncertain about using that much paper.
[10:08:58] <CaptHindsight> think plywood but with other composites
[10:09:03] <malcom2073> Paper isn't that cheap
[10:09:04] <XXCoder1> yea
[10:09:09] <XXCoder1> that too
[10:09:15] <CaptHindsight> carbon fiber prepreg
[10:09:38] <CaptHindsight> or fiberglass prepreg for lower cost applications
[10:10:20] <CaptHindsight> I get booted for discussing these applications in reprap and similar
[10:10:41] <CaptHindsight> it's like they can't deal with actual science and engineering
[10:10:43] <malcom2073> it's not what you say, it's how you say it.
[10:10:58] <CaptHindsight> yeah, like school
[10:11:01] <malcom2073> Like life.
[10:11:04] <malcom2073> :)
[10:11:23] <CaptHindsight> can't handle opposing views
[10:11:24] <XXCoder1> capt toxic fanbois
[10:11:37] <malcom2073> Sure they can, I talk all the time in there about linuxcnc and about my ballscrew precision design
[10:11:40] <XXCoder1> only thing worse than enemies of your product is toxic fanbois
[10:11:51] <malcom2073> And about how flimsy reprap is
[10:12:38] <malcom2073> It's about how you say it
[10:12:54] <CaptHindsight> there's a whole generation of people that react to opposing views with hostility
[10:13:32] <CaptHindsight> they have been well trained
[10:14:33] <CaptHindsight> lots of dreamers that don't really see the limitations of the FDM with flimsy frames
[10:14:51] <CaptHindsight> and a limited range of materials
[10:15:35] <CaptHindsight> that type of FDM won't change the manufacturing world
[10:16:18] <malcom2073> See if you go in there assuming they're going to be hostile, they will. If you go in there assuming they're normal people and talk to them as such, then they're quite reasonable. Like any IRC channel really
[10:16:30] <malcom2073> Yes there are a few fanatics, there always will be
[10:17:07] <malcom2073> FDM won't change the world, but it will change quite a few people. It got me into CNC, and here I am trying to build a wood router and looking for a CNC mill to buy now :)
[10:17:38] <CaptHindsight> it's more the real sociopaths and narcissists that can't deal with hearing that the king is naked
[10:18:18] <malcom2073> Then why go poking at them and yelling that the king is actually naked? I don't care that he's naked, it doesn't affect me any heh
[10:18:48] <CaptHindsight> and those with businesses based on taking advantage of people that are just learning
[10:19:06] <malcom2073> kickstarter.com? :P
[10:19:15] <CaptHindsight> there's no yelling or poking
[10:19:17] <malcom2073> Can't stand that website heh
[10:19:30] <CaptHindsight> the lawsuits have begun
[10:19:39] <CaptHindsight> projects that didn't deliver
[10:20:47] <malcom2073> Good
[10:21:15] <malcom2073> That's 3d printing in general just because it's a buzz word
[10:21:22] <Tom_itx> that was a point i noticed. nearly every successful reprapper was in channel selling something
[10:22:41] <CaptHindsight> it used to be about making things work
[10:22:43] <Tom_itx> they got mad at me for logging the channel too
[10:22:48] <malcom2073> Super low cost of entry, it's easy to "design" things, print them, and sell them to others. (Design is used lightly)
[10:22:56] <malcom2073> Really? it's publicly logged
[10:22:57] <CaptHindsight> now it's just sales agendas
[10:22:58] <Tom_itx> they said the things they said in there could affect their jobs
[10:23:08] <Tom_itx> so i replied... don't say it then
[10:23:10] <XXCoder1> dont dont fucking say it
[10:23:14] <XXCoder1> er then
[10:23:16] <malcom2073> lol
[10:23:26] <CaptHindsight> heh
[10:23:47] <Tom_itx> i think i eventually lost interest and quit anyway
[10:26:13] <CaptHindsight> a laminate printer is capable of making some rather complex and rigid parts
[10:27:09] <malcom2073> Yeah, it's not for everyone. You really have to have a specific purpose in mind (be that printing more printers... ugh...) or some intent for it for it to really be useful, it's not like a mill wher eit can be used for almost anything
[10:27:14] <CaptHindsight> cutting laminate wastes too much material, but if you can weave or layer fibers as you fill with resin there is very little waste
[10:28:06] <CaptHindsight> the GGG extruders are like glue guns, a proper gear pump can handle all sorts of plastics and composites
[10:29:00] <CaptHindsight> large inkjet printers use valves for jetting with nozzle spacing similar to what FDM requires
[10:29:50] <CaptHindsight> I thought someone would beat me to it but a nozzle array that scans vs vector would have much higher print/fill rates
[10:30:09] <XXCoder1> finally found out why one block jams. one of its bearing channels is jammed
[10:30:14] <XXCoder1> balls dont rotate freely
[10:30:35] <CaptHindsight> crud or square bearing?
[10:30:36] <malcom2073> CaptHindsight: I've often wondered why the pellet extruders didn't use a heated gear pump
[10:31:02] <CaptHindsight> http://www.3ders.org/articles/20140518-sculptify-3d-printer-printing-directly-with-plastic-pellets-soon-on-kickstarter.html
[10:31:14] <malcom2073> CaptHindsight: yeah when I see tech details I'll believe it :)
[10:31:16] <CaptHindsight> no video or pics so I'm not usre about this one either
[10:31:51] <CaptHindsight> nice bags of pellets though
[10:32:27] <malcom2073> They are pretty, and prettysells
[10:32:53] <CaptHindsight> plastic extruders rely mostly on the friction of the screws to melt the pellets
[10:32:54] <XXCoder1> wha? one bearing channel fail. balls dont even reach higher than plastic so plastic is touching rails and balls isnt doing anything
[10:33:44] <CaptHindsight> but with really small nozzles a heater is fine
[10:34:06] <CaptHindsight> whats the viscosity of molten PLA?
[10:34:11] <malcom2073> CaptHindsight: Really? for like, injection moulding machines?
[10:34:45] <CaptHindsight> I bet none of the pro reprap makers have ever measured
[10:35:51] <CaptHindsight> http://brianbenchoff.files.wordpress.com/2012/03/extruder.gif
[10:36:14] <CaptHindsight> they also use heaters to more tightly control the heat to the zones in the barrel
[10:36:25] <malcom2073> CaptHindsight: yeah thta looks like the filastruder designs heh
[10:36:55] <CaptHindsight> http://image.made-in-china.com/2f0j00qsrTFDMaHLol/Kaichi-Co-Rotating-Twin-Screw-Extruder-SHJ-75-.jpg
[10:37:14] <CaptHindsight> that barrel has 6 external heaters
[10:37:44] <CaptHindsight> but that will extrude a 2-3" dia solid
[10:38:14] <CaptHindsight> for FDM it's 0.01"
[10:39:27] <CaptHindsight> grind the pellets smaller, just melt and extrude pellets as you print
[10:39:43] <CaptHindsight> grinding pellets is really low cost
[10:40:12] <CaptHindsight> PLA powder
[10:40:23] <CaptHindsight> makes the design even easier
[10:40:28] <malcom2073> Yeah, there's a bunch of designs for people making their own filament extruders, and then taking that and pritning with it
[10:41:08] <malcom2073> The big problem is, the apparatus to do so is huge, so putting it on a mobile print head doesn't make much sense. Options include making a stationary print head and a moving bed, or somehow poping the hot filament to the extruder keepign it hot
[10:41:16] <CaptHindsight> this would use PLA powder, no filament
[10:41:22] <malcom2073> Oh!
[10:41:37] <CaptHindsight> so the extruder would lighter
[10:41:42] <malcom2073> So you'd pipe pressurised powder to the hotend, and it would melt/extrude it there?
[10:41:42] <CaptHindsight> would be
[10:41:52] <malcom2073> via a flexiable hose I assume
[10:42:02] <CaptHindsight> powder at the head
[10:42:09] <CaptHindsight> melt and extrude
[10:42:23] <malcom2073> Right, but an auger or gear drive setup is heavy
[10:42:33] <malcom2073> Or am I misunderstanding?
[10:42:41] <CaptHindsight> yes, thats why the powder
[10:43:06] <malcom2073> how do you move the powder?
[10:43:21] <CaptHindsight> you can do it the way you were thinking but under high pressure
[10:44:00] <CaptHindsight> move the powder with a gear
[10:44:09] <malcom2073> Ah, just a small gear at the head?
[10:44:25] <CaptHindsight> yes, vs big 10lb gear pump
[10:44:35] <malcom2073> Gotcha, I like the idea
[10:44:51] <malcom2073> Would also make recycling scrap work, since everything is getting ground down to a fine powder
[10:45:11] <CaptHindsight> yeah, powder makes more sense
[10:45:29] <CaptHindsight> you can also extrude plastic powders used for SLS
[10:46:11] <CaptHindsight> or you can deposit powder like metal printers and use a laser or plasma to melt it
[10:46:13] <malcom2073> So the grinder would be dual use
[10:46:49] <CaptHindsight> deposit plastic powder and melt it at the surface
[10:47:01] <malcom2073> Yeah I saw a metal printer that did that
[10:47:21] <CaptHindsight> yeah, so same thing for plastics
[10:48:33] <XXCoder1> hm. one bearing block had one too many ball in one circuit and other one had one ball too few
[10:48:38] <XXCoder1> moved one ball and it moves better
[10:48:52] <CaptHindsight> always count your balls!
[10:48:53] <malcom2073> XXCoder1:Oops! Chinese?
[10:48:58] <XXCoder1> yep
[10:49:04] <malcom2073> always make sure you have the same number of balls on both sides... err I mean both bearings :P
[10:49:15] <XXCoder1> lol
[10:50:10] <XXCoder1> wow
[10:50:16] <XXCoder1> bunch metal stuff in this one
[10:50:23] <XXCoder1> glad I'm cloeaning em out
[10:51:02] <CaptHindsight> we also laser cure powdercoatings, it works like a giant color laser printer
[10:51:17] <XXCoder1> woot smoother
[10:52:38] <CaptHindsight> malcom2073: http://www.youtube.com/watch?v=s9IdZ2pI5dA
[10:52:48] <CaptHindsight> with metals ^^
[10:53:30] <CaptHindsight> this is what the DIYers should be working on
[10:53:48] <CaptHindsight> make machines that make real useful parts
[10:54:07] <SpeedEvil> An alternative to drilling accurately.
[10:54:09] <SpeedEvil> http://www.amazon.de/Neutechnik-Wunder-D%C3%BCbel-Korrekturd%C3%BCbe-24-St%C3%BCck/dp/B001VVZ7QO/ref=sr_1_19?s=diy&ie=UTF8&qid=1400943419&sr=1-19&keywords=Neutechnik
[10:54:12] <malcom2073> CaptHindsight: yeah I got that link bookmarked :)
[10:54:15] <malcom2073> I love that concept
[10:54:17] <SpeedEvil> Genius.
[10:54:19] <CaptHindsight> low res deposition with milling
[10:54:33] <Tom_itx> what about compressed powdered metals?
[10:54:58] <XXCoder1> yeah love that video
[10:55:02] <CaptHindsight> metal injection molding
[10:55:15] <CaptHindsight> have to go, bbl
[11:01:29] <XXCoder1> I still dont understand why this bearing works one way (roughly) and barely work other way
[11:02:42] <CaptHindsight> malcom2073: they could also work on low pressure injection molding, check out Henkle
[11:03:09] <CaptHindsight> http://www.henkel.com/low-pressure-injection-molding-33511.htm
[11:03:46] <CaptHindsight> easy tabletop and can be low cost to make multiple parts in short times
[11:05:40] <malcom2073> CaptHindsight: hmm, I'll look at it
[11:08:17] <SpeedEvil> CaptHindsight: hotmelt is awesome
[11:10:32] <XXCoder1> jeez
[11:10:38] <XXCoder1> its finally unjammed
[11:11:01] <XXCoder1> bunch of tiny black plastic and unknown light brown stuff fell out so far
[11:12:22] <malcom2073> Heh
[11:12:23] <malcom2073> that's not good
[11:12:47] <XXCoder1> in least it seems to move fine with bit more force than others
[11:12:56] <XXCoder1> its fine for first cnc
[11:15:31] <XXCoder1> yep
[11:15:45] <XXCoder1> it dont jam or only work one way on rail anymore
[11:15:55] <XXCoder1> dont seem to take any more force to move it than others
[11:15:56] <XXCoder1> woot
[11:18:57] <XXCoder1> heh could buy new bearing parts, but I has low fund, lots hours
[11:18:59] <XXCoder1> so yeah lol
[11:19:39] <malcom2073> heh
[11:19:59] <XXCoder1> I still need few more stuff before I can build cnc
[11:20:22] <XXCoder1> couplers, router motor itself
[11:20:35] <malcom2073> nice, what size are you building?
[11:20:41] <XXCoder1> bunch of those specific screws that work with motors and stuff
[11:20:58] <XXCoder1> 300mmx600mmx600mm is rails size
[11:21:15] <XXCoder1> I guess working area would be 1.4'x1.4'x5 inch
[11:22:07] <XXCoder1> ordered screws but havent gotten em yet (ballscrews not screws to mount motors so on I menioned earlier)
[11:22:31] <XXCoder1> I might buy decent motor mount blocks but dunno
[11:26:30] <XXCoder1> think this is overkill?
[11:26:31] <XXCoder1> <-- GeoManCam has quit (Changing host)
[11:26:31] <XXCoder1> --> GeoManCam (~GeoManCam@unaffiliated/geomancam) has joined #freenode
[11:26:36] <XXCoder1> wtf
[11:26:41] <XXCoder1> jeez

[11:27:07] <XXCoder1> once a while hexchat copies string when I click on it
[11:27:14] <XXCoder1> annoying, wish I could disable copy on click
[11:28:26] <XXCoder1> finally found setting to disable it. woot
[11:29:17] <XXCoder1> anyway malcom2073 what ya think
[11:29:53] <malcom2073> Nice
[11:30:05] <malcom2073> I don't know,
[11:30:13] <malcom2073> depends on your frame I guess?
[11:30:23] <XXCoder1> it'll be wood frame
[11:30:33] <XXCoder1> mostly regular wood and plywood
[11:30:36] <malcom2073> Why not make wood spacers?
[11:31:15] <XXCoder1> other way would be to use pipes and screws
[11:31:27] <XXCoder1> I'd have to be pretty exact with pipe sizes though
[11:32:51] <malcom2073> I don't know, not much on design yet, still learning :)
[11:33:05] <XXCoder1> basically nema23 - steel sheet - pipes with screw inside - steel plate - wood frame of cnc
[11:35:33] <XXCoder1> found example
[11:35:34] <XXCoder1> https://cdn.shopify.com/s/files/1/0318/9541/t/2/assets/slideshow_1.jpg?472
[11:44:24] <XXCoder1> LOL

[11:57:32] <malcom2073> XXCoder: As someone who used to be in airports twice a week, that outlet picture is evil
[11:57:44] <XXCoder> lol
[11:57:48] <XXCoder> I bet
[11:57:59] <XXCoder> you can see marks on it
[11:58:00] <malcom2073> People get MEAN over outlets
[11:58:03] <XXCoder> olviously someone tried
[11:58:55] <IchGuckLive> hi all
[11:59:00] <XXCoder> hey ich :)
[11:59:23] <XXCoder> wanted to ask, is it worth it to buy http://www.ebay.com/itm/3-pack-Nema-23-mount-for-stepper-CNC-machined-in-Detroit-Free-USA-shipping-/291054398465?pt=LH_DefaultDomain_0&hash=item43c431ac01
[11:59:33] <XXCoder> or is it overkill for wood frame machine
[12:15:06] <SpeedEvil> Seems to be little reason not to make the stepper mounts out of wood.
[12:15:24] <SpeedEvil> Though you'd need to make them hold the ends, and blow air in
[12:18:12] <Jymmm> XXCoder: That's $18/each, d you ever think you might retrofit a minimill in the future?
[12:19:44] <archivist> I make the mounts as I need, cheapest
[12:19:58] <Jymmm> XXCoder: Else you could just get some thick walled aluminum tubing, cut to length to make standoffs
[12:22:35] <Jymmm> XXCoder: I guess you could do the same with two 1/2" lumber 2"x2" blocks, with two holes drilled thru them too.

[12:36:13] <IchGuckLive> im off nice sky going to the telescope watching stars tonight BYE
[12:52:23] <XXCoder> Jymmm: thanks
[12:52:28] <XXCoder> sorry had unexpected quest
[12:52:37] <Jymmm> XXCoder: =)
[12:53:14] <Jymmm> XXCoder: If you are being cheap, get you some IPE amke make em.
[12:53:21] <XXCoder> IPE?
[12:53:45] <XXCoder> I'm not super cheap, just considering if worth it for wood machine or not
[12:54:17] <Jymmm> XXCoder: Just make a "U" out of some scrap
[12:54:46] <XXCoder> I think its bit easier for me to just use legths of metal pipe
[12:54:54] <XXCoder> with steel plates ends
[12:55:13] <Jymmm> You could use you double nuts too
[12:56:14] <Jymmm> bolt motor nut nut space nut mount nut
[12:56:37] <XXCoder> ahh
[12:57:03] <Jymmm> no tubing required
[12:57:17] <zultron> zq, github/machinekit is the right place for patches against machinekit, yes. Did you manage to get on the list?
[13:29:44] <zeeshan> Einar1: you were RIGHT
[13:29:47] <zeeshan> it was STICTION
[13:32:04] <archivist> how accurate now
[13:32:35] <zeeshan> backlash 0.0005
[13:32:41] <zeeshan> linear travel 0.0005
[13:32:50] <zeeshan> i only show .050" travel in the video
[13:33:02] <zeeshan> but i've done it to 8" nice by resetting the dial indicator every 1"
[13:33:13] <zeeshan> same consistent results
[13:34:16] <archivist> so...you have had all day....what have you made on it :)
[13:34:25] * archivist ducks
[13:34:41] <zeeshan> archivist: its only moving in Z direction
[13:34:47] <zeeshan> my X direction power supply shot out plasma
[13:34:56] <zeeshan> piece of shit defective automationtechnologies power supply
[13:35:11] <zeeshan> i know its a defective power supply, cause i swapped the wires to the other one and everything works fine
[13:35:32] <archivist> I had a chines psu arse splode too
[13:35:44] <zeeshan> =/
[13:35:48] <zeeshan> what specs?
[13:35:54] <zeeshan> this is 600W one 72vdc 8a
[13:35:59] <zeeshan> i shoulda just bought a 20A toriodal.
[13:36:20] <zeeshan> https://www.youtube.com/watch?v=JVUGxGwsRWI
[13:36:22] <archivist> was a 60V 500W
[13:36:38] <zeeshan> kinda boring video and damn it i spelt backlash wrong
[13:38:42] <XXCoder> http://io9.com/the-beautiful-stones-created-by-layers-of-car-paint-1581007328 nice
[13:38:56] <zeeshan> XXCoder: ^ video shows 0.0005 backlash
[13:39:11] <zeeshan> on linearmotionbearings2008 screw
[13:39:25] <XXCoder> sorry handheld I cannt watch
[13:49:50] <jdh> get bigger balls
[13:50:04] <XXCoder> balls?
[13:50:12] <zeeshan> anyone know who the hell
[13:50:15] <zeeshan> arturo is?
[13:50:32] <jdh> cnc4pc d00d
[13:50:49] <XXCoder> Arduino?
[13:50:53] <zeeshan> why would automationtechnolgoies forward my email 'I purchased 2 72VDC 8A power supplies from your store a couple months ago. I finally powered them up in my system and one of them instantly fried shooting sparks everywhere. I put the other spare power supply I bought from you in the same connections and it works 100% fine. This leads me to believe the power supply was defective. Can I still warra
[13:50:57] <zeeshan> to him?
[13:51:40] <jdh> did you buy it from cnc4pc?
[13:51:43] <zeeshan> no
[13:51:46] <zeeshan> from automationtechnologies
[13:51:57] <XXCoder> that company may buy from cnc4pc
[13:52:10] <jdh> cnc4pc resells keling/automationtech stuff
[13:52:51] <archivist> or they all buy direct for cheapness
[13:53:09] <zeeshan> i really shoulda bought the toriodal supply
[13:53:11] <zeeshan> it was the same cost.
[13:53:12] <zeeshan> :(
[13:53:19] <jdh> cnc4pc reuses keling part numbers of leadshine stuff
[13:53:48] <pcw_home> Passive supplies are easily fixable also...
[13:53:56] <zeeshan> seriously
[13:54:00] <zeeshan> a power supply shouldnt shoot sparks
[13:54:04] <zeeshan> it shot plasma out the fan rofl
[13:54:29] <archivist> the switcher devices asplode
[13:54:32] <zeeshan> and there was some nice blue smoke
[13:54:35] <pcw_home> thats entertaining
[13:54:48] <zeeshan> the plasma went right onto my motherboard and cpu fan
[13:55:04] <zeeshan> cause i've directed the fans in a way so the psu fans blow onto the cpu fan which blows to the exit fan
[13:55:12] <zeeshan> but in doing so, i also redirected the plasma :p
[13:57:57] <zeeshan> http://i.imgur.com/9FpwxME.png
[13:58:02] <zeeshan> yesterday i generated this curve
[13:58:18] <zeeshan> i bet there is an periodic error in the dial indicator
[13:58:26] <zeeshan> stiction
[13:58:37] <zeeshan> i'm so glad its fixed now
[13:58:48] <jdh> build a pneumatic thumper and tap it while you are cutting parts
[13:59:07] <zeeshan> jdh: the machine isnt th e problem
[13:59:09] <zeeshan> the indicator was
[13:59:11] <zeeshan> http://i.imgur.com/FSZbsdA.jpg
[13:59:33] <zeeshan> the power supply that shot plasma is the very back one on the bottom right
[13:59:33] <jdh> irrelavent.
[14:01:38] <jdh> I should have gotten some of those tiny keling drives instead of the cheap huge ones.
[14:01:58] <zeeshan> my friend sat on the carriage while i jogged at 150ipm
[14:02:00] <zeeshan> hes 240lb
[14:02:15] <zeeshan> did it was for 1 minute and neither the stepper or the drive gets hot
[14:02:31] <zeeshan> its like luke warm water
[14:31:36] <tom_R2E3> hi
[14:31:50] <tom_R2E3> think I already know the answer to this but i'll ask anyway:
[14:32:16] <tom_R2E3> I've got two 24cpr encoders which I'd like to use for feed and speed override
[14:32:30] <tom_R2E3> I'm using Mesa 7i77
[14:32:51] <tom_R2E3> my Field voltage is 24, and the encoders are 5V
[14:33:59] <tom_R2E3> So, I was thinking to use the mpg pins, 16-19
[14:34:11] <pcw_home> if you use the 7I77s MPG inputs, they should just work
[14:34:23] <tom_R2E3> But i've already used two for my MPG..
[14:34:37] <tom_R2E3> I need 6
[14:34:57] <pcw_home> need another mode...
[14:36:08] <pcw_home> or better support of input the threshold setting
[14:36:50] <pcw_home> I think the 7I43 has 4 encoder inputs
[14:37:09] <pcw_home> so thats an option7i73
[14:37:16] <pcw_home> 7I73 I mean
[14:39:42] <tom_R2E3> yeah
[14:40:12] <pcw_home> or a software encoder in the other FPGA connector GPIO bits
[14:40:12] <tom_R2E3> Could I move my MPG (100cpr) to one the of the axis encoder inputs that i'm not using?
[14:40:56] <pcw_home> actually better to use the axis encoder for you feed override
[14:41:27] <pcw_home> (especially if you have a detented 100 PPR MPG)
[14:42:12] <pcw_home> since the MPG inputs are 1X count mode and axis encoders dont have that mode
[14:43:27] <pcw_home> so if you have a free axis encoder that should work fine but we always prefer if you buy more stuff :-)
[14:43:38] <tom_R2E3> My MPG is 100ppr with detent. My feed and speed dials are 24ppr with detent
[14:44:35] <tom_R2E3> why is the 24ppr better for the axis encoder?
[14:45:18] <pcw_home> its not the PPR, on a MPG you want 1x mode so each tic is .001 etc
[14:45:48] <tom_R2E3> OK, and the Mode 3 pins 16-19 do this
[14:45:58] <pcw_home> on the speed/feed override you are less likely to care
[14:46:15] <tom_R2E3> but the axis encoder input doesn't
[14:46:17] <pcw_home> yes 1X mode s the default
[14:46:22] <tom_R2E3> OK
[14:46:43] <tom_R2E3> so, i'll try with axis 5 and 6
[14:46:44] <pcw_home> on 24 PPR you probably want 4X mode anyway
[14:47:50] <tom_R2E3> does the common want to be 5v or ground?
[14:48:45] <pcw_home> common for field inputs is field input common
[14:48:47] <pcw_home> common for encoders is ground
[14:50:41] <tom_R2E3> OK so QA0, QB0 and GND
[14:50:45] <tom_R2E3> i'll give it a try
[14:50:46] <pcw_home> (the axis encoders have a ground pin) the MPG encpder need their ground pin returned to the Field voltage common
[15:43:12] <tom_R2E3> Yep that's counting
[15:43:35] <tom_R2E3> took me a while to figure out I needed to change the jumpers to single
[15:43:44] <tom_R2E3> Thanks for your help Peter

[21:23:02] <Jymmm> New digital scope, what am I doing wrong... I engage a laser diode but all I get is a blip when I turn it on/off
[21:23:12] <Jymmm> I can see the diode is on, but no signal on the scope
[21:36:27] <jdh> what are you hooked upto
[21:42:15] <pcw_home> AC coupled?
[22:13:34] <Jymmm> I think AC, let me check
[22:33:50] <soundhound> Hi guys
[22:35:21] <soundhound> Can anyone tell me how to lower decimals to 1 for gladevcp spindle widget?
[23:00:05] <cmorley> yes edit the GLADE file, changing the 'text template' of the relevant Hbar widget to something like %.1f
[23:01:32] <Tom_itx> change <format>"4.1f"</format> to <format>".1f"</format> in the xml file?
[23:01:53] <Tom_itx> or 0.1
[23:01:54] <Tom_itx> ?
[23:03:05] <Tom_itx> Jymmm, what scope did you go with?
[23:03:46] <cmorley> I believe either will work and its easy to try
[23:04:33] <Tom_itx> yeah, somewhere in the code i had to scale mine too iirc
[23:06:44] <Tom_itx> soundhound, my configs are here if you wanna peek: http://tom-itx.no-ip.biz:81/~webpage/cnc/configs/sherline/
[23:07:06] <Tom_itx> display.xml and postgui.hal would be the relevant files
[23:08:13] <soundhound> Glade uses XML?
[23:08:15] <Tom_itx> ahh, the scaling was done in sherline.hal
[23:08:36] <Tom_itx> no that's pypcv
[23:08:48] <Tom_itx> sry
[23:13:33] <soundhound> Ok ill try that %.1f in the designer, thx
