[00:00:31] <pink_vampire> i have some issue with my machine
[00:00:34] <pink_vampire> XXCoder:
[00:00:41] <XXCoder> yeah whats wrong?
[00:00:50] <pink_vampire> emf
[00:01:18] <pink_vampire> i'm not sure why the shielding is not working
[00:01:19] <MacGalempsy> hello...
[00:01:27] <pink_vampire> helloo
[00:01:30] <XXCoder> is it grounded properly?
[00:01:41] <pink_vampire> yes
[00:01:52] <XXCoder> unfortunately thats extent of my knowledge lol
[00:02:03] <XXCoder> my 3d printer isnt even sheilded,
[00:02:13] <MacGalempsy> mine neither
[00:02:15] <pink_vampire> I covered the motor with aluminum foil
[00:02:45] <pink_vampire> and i can't see any change
[00:02:49] <MacGalempsy> how do you know its emf and not a bad signal?
[00:03:13] <XXCoder> I rewired my bad nema17 and tested uit. broken still
[00:03:37] <pink_vampire> my s meter on my radio is 2 when the machine is off and 9-10 when is on
[00:03:49] <MacGalempsy> dont those demag once you pull the shaft out?
[00:04:25] <XXCoder> MacGalempsy: it still had very strong magnet field
[00:05:15] <MacGalempsy> well yesterday was a bust on the 4th axis
[00:05:42] <MacGalempsy> it spins on power but no encoder signal
[00:06:11] <MacGalempsy> wierd part is raw counts would increase slowly...
[00:06:34] <pink_vampire> encoder problem is dangerous
[00:07:00] <MacGalempsy> costly is more like it
[00:08:06] <pink_vampire> why?
[00:08:18] <pink_vampire> encoder is about 40$
[00:09:02] <MacGalempsy> the encoder i need to replace is 1250cpr
[00:09:17] <MacGalempsy> hollow shaft encoder
[00:10:27] <pink_vampire> ok.. that going to be a bit more heavy.,
[00:14:53] <pink_vampire> the best music is the music you never heard before, and I found the best playlist on youtube, soo awesome music, I don't want to do anything just dance like no tomorrow
[00:17:24] <mike_LCNC> can anyone help with getting my scale?
[00:17:55] <mike_LCNC> scale for servo with 2500ppr quad encoder
[00:20:03] <pink_vampire> what do you mean?
[00:23:20] <pink_vampire> mike_LCNC:
[00:24:02] <mike_LCNC> yes?
[00:24:24] <mike_LCNC> trying to calculate scale in the ini file.
[00:25:25] <pink_vampire> i'm not using linux cnc, but are you talking about the ratio between the pulses to the travel?
[00:25:32] <mike_LCNC> yes
[00:26:00] <pink_vampire> that is very easy to calculate
[00:26:02] <MacGalempsy> mike_lcnc: what is your screw tpi?
[00:26:10] <mike_LCNC> mo screw
[00:26:14] <pink_vampire> what is you ballscrew pitch?
[00:26:14] <mike_LCNC> no screw
[00:26:28] <pink_vampire> belt?
[00:26:29] <mike_LCNC> rack and pinion
[00:26:44] <pink_vampire> ok.. same thing
[00:27:07] <pink_vampire> what is the tooth per inch
[00:27:31] <pink_vampire> or per mm
[00:28:03] <pink_vampire> and what it the tooth number on the gear
[00:28:18] <pink_vampire> mike_LCNC: ?
[00:28:23] <MacGalempsy> how far does it move on 1 revilution?
[00:28:36] <MacGalempsy> is there an index pulse?
[00:29:20] <mike_LCNC> 7.84 inches per turn
[00:29:35] <pink_vampire> do you want it metric?
[00:29:48] <mike_LCNC> no
[00:29:54] <pink_vampire> ok
[00:30:01] <pink_vampire> 7.84/2500
[00:30:03] <mike_LCNC> the encoders are 2500ppr
[00:30:06] <mike_LCNC> quad
[00:30:24] <mike_LCNC> theres a gear involved
[00:30:30] <pink_vampire> that is the travel per pulse
[00:30:56] <pink_vampire> the travel per inch is 2500/7.84
[00:31:19] <MacGalempsy> if you use the lcnc wizard there is a section in there
[00:31:33] <MacGalempsy> to use the gears
[00:32:02] <pink_vampire> 318.87755102 pulses per 1 inch
[00:33:36] <mike_LCNC> the gear is 10 to 1
[00:34:27] <MacGalempsy> pink_vampire: i dont understand how the shield is not working right, its gaussian
[00:34:46] <pink_vampire> no difference
[00:35:06] <mike_LCNC> no difference for what?
[00:35:23] <MacGalempsy> unless the cnxn isnt good. perhaps the soildering is bad
[00:35:24] <mike_LCNC> the motor has to turn 10 times for one turn of the pinion
[00:36:07] <mike_LCNC> pink?
[00:36:12] <MacGalempsy> so 3188
[00:36:29] <pink_vampire> i mean that the noise level is the same with or without the shielding
[00:36:33] <pink_vampire> MacGalempsy:
[00:36:36] <mike_LCNC> but with the quad encoders, you need to multiply by 4?
[00:37:14] <MacGalempsy> but the shield should cancel the noise. have you tried a rf filter? looped magnet?
[00:38:05] <mike_LCNC> You have the shield grounded on both sides?
[00:38:07] <MacGalempsy> trial and error is paramount in your situation
[00:38:14] <pink_vampire> no
[00:38:15] <MacGalempsy> no
[00:38:23] <pink_vampire> just one side
[00:39:01] <MacGalempsy> is the shield crimped or soldiered to the cnxn?
[00:39:24] <pink_vampire> it's aluminum foil
[00:39:38] <pink_vampire> several layers
[00:40:12] <MacGalempsy> do you get continuity between the foil and cnxn?
[00:40:30] <pink_vampire> what is cnxn?
[00:40:46] <MacGalempsy> the grounded end of the shield?
[00:40:56] <pink_vampire> yes
[00:41:50] <MacGalempsy> how about the ground and the foil at the opposite end?
[00:41:56] <bnz> you should terminate the shield at the end that generates the signal. i.e. ground at the encoder end
[00:42:20] <bnz> and only ground at one end. other wise its just a conductor for some of the ground current
[00:42:46] <pink_vampire> there is few mV of ac voltage between the shield and the ground, but other wires that close to the motor wires show 4-7volts between them to the ground
[00:43:20] <bnz> you might also have to add a capacitor to across the power pins of the encoder if you have noise on the supply side of things
[00:43:45] <pink_vampire> the encode wire is not the issue
[00:44:25] <MacGalempsy> shielded motor wires?
[00:44:32] <pink_vampire> the issue is the motor / motor wires/ driver transmit a lot of emf
[00:44:34] <bnz> are your motor wires twisted? i.e. the two wires for phase A are twisted together and the B phase are twisted together so you have two twists.. that should help the noise from the motors.
[00:44:50] <pink_vampire> it's dc motor
[00:44:58] <bnz> or your DC motor wires
[00:45:04] <bnz> i forgot you run servos
[00:45:04] <pink_vampire> no
[00:45:25] <bnz> you can twist the + & - that will helps some.
[00:46:03] <pink_vampire> maybe aluminum foil is not good?
[00:46:14] <pink_vampire> i will try to twist them
[00:47:24] <MacGalempsy> is the foil a tight fit?
[00:47:39] <pink_vampire> almost
[00:48:10] <MacGalempsy> just buy a few feet of shielded cable. and ditch mach3
[00:48:42] <pink_vampire> any recommend cable??
[00:49:01] <MacGalempsy> dc servo?
[00:49:10] <pink_vampire> yes
[00:49:36] <MacGalempsy> 14/3?
[00:50:00] <MacGalempsy> just take your wire with you and match it.
[00:51:09] <MacGalempsy> Are the wires in a common housing?
[00:52:01] <MacGalempsy> oh. i got to hit the sack. supposed to help a friend move in 7hrs!
[00:52:10] <MacGalempsy> gn8
[00:55:23] <pink_vampire> I got the motor opend!!!!!!!!!!!!!!!!!!!
[00:55:36] <pink_vampire> that what soooo hard to open!
[00:56:14] <XXCoder> heh
[00:56:46] <XXCoder> why opening it?
[01:00:12] <pink_vampire> i want to replace the original chinesium wire with something better
[01:01:48] <pink_vampire> i took a picture
[01:02:08] <XXCoder> chineseium wire eh
[01:02:14] <pink_vampire> http://i.imgur.com/w4kmmNP.png
[01:03:47] <XXCoder> so replacing wires
[01:05:06] <pink_vampire> but with what wire?
[01:09:23] <mike_LCNC> can P be a negative number?
[01:09:41] <pink_vampire> p?
[01:10:30] <XXCoder> pink_vampire: thought you was replacing wires on your servo
[01:10:39] <mike_LCNC> PID
[01:10:42] <pink_vampire> no
[01:11:05] <pink_vampire> i just wanted to see whats going on inside
[01:11:10] <XXCoder> ahh ok
[01:11:42] <pink_vampire> and looking for a good cable that will take all the noise
[01:18:29] <XXCoder> theres cables that are sheilded pairs inside
[01:18:33] <XXCoder> very well sheilded
[01:18:48] <XXCoder> though no idea which would support your machine current requirements
[01:23:55] <pink_vampire> I'm using less then 10% of the power of them
[01:24:11] <pink_vampire> and hope to rebuild the whole rails
[01:24:36] <pink_vampire> XXCoder:
[01:24:39] <XXCoder> you know a lot more about those than I do heh
[01:25:30] <pink_vampire> that amazing that i can run it almost in 3000mm/min and it take less then 200w
[01:30:33] <pink_vampire> http://www.sabcable.com/en/products/servo-motor-cables.html
[01:30:39] <pink_vampire> XXCoder:
[01:30:49] <XXCoder> interesting
[01:31:07] <XXCoder> few sheilded options there
[01:31:48] <pink_vampire> what is the most shielded one?
[01:32:06] <XXCoder> I dont know sadlt
[01:33:21] <pink_vampire> https://www.youtube.com/watch?v=eC-F_VZ2T1c&list=PLrEnWoR732-D67iteOI6DPdJH1opjAuJt&index=40
[01:33:47] <XXCoder> https://youtu.be/8HZFY4Xti7k pink_vampire
[01:41:22] <mike_LCNC> how do you set the axis to show just x y z dro?
[01:44:32] <archivist> I think it shows axes you have configured
[02:33:35] <Deejay> moin
[02:34:27] <pink_vampire> hi Deejay
[02:34:39] <pink_vampire> 3
[02:34:40] <pink_vampire> 2
[02:34:41] <pink_vampire> 1
[02:34:45] <pink_vampire> g8
[02:35:49] <Deejay> g7
[02:35:50] <Deejay> g6
[02:35:52] <Deejay> ... ;)
[02:35:53] <XXCoder> going to bed pink_vampire ?
[02:35:54] <Deejay> hi pink
[02:36:05] <Deejay> hi XXCoder
[02:36:14] <XXCoder> yo
[02:37:20] <pink_vampire> I say g8 to Deejay
[02:37:30] <XXCoder> lol ok
[02:38:18] <pink_vampire> I have the feeling...
[02:38:40] <Deejay> hmm, and what should g8 mean?
[02:39:14] <pink_vampire> good night
[02:39:22] <Deejay> gn8 pink
[02:39:26] <Deejay> its early morning here
[02:39:28] <Deejay> ;)
[02:39:38] <archivist> get you lazy bums
[02:39:45] <archivist> get up
[02:40:31] <Deejay> dont stress me, its weekend ;)
[02:41:54] <XXCoder> Deejay: get both feet on floor and briefly lift yourself off chair. thats techinically have gotten up.
[03:41:56] <LoveMHz> Anyone using Fusion360 through VBox?
[04:04:04] <Jymmm> LoveMHz: http://stackoverflow.com/questions/34722033/rendering-in-fusion-360-with-virtualbox
[04:05:07] <XXCoder> I do, and 256 mb virtual video memory is not enough :(
[04:05:27] <XXCoder> I asked vm devs and they all say 256 mb is all everything needs. ugh
[04:08:10] <Jymmm> 512KB of ram is all you need too
[04:08:17] <XXCoder> heh
[04:08:19] <LoveMHz> But I have 6GB VRAM and hardly use any of it...
[04:08:23] <XXCoder> that was sadly a misquote
[04:08:46] <Jymmm> XXCoder: shut yer pie hole and just go with it damnit!
[04:08:49] <XXCoder> he was talking about 512k stack memory. which is basically true, nothing needed more than 512 mb stack memory so far.
[04:09:28] <LoveMHz> Looks like I'm going to give VMware a try
[04:12:06] <Jymmm> Ewwwwwwwwwwwwwwwwwwwwwwwwwwww
[04:13:45] <LoveMHz> Well I'm running out of options!
[04:14:16] <Jymmm> LoveMHz: At that rate, I'd just buy a spare box before I'd ever touch a vmware product (esxi being the only possible exception)
[04:14:29] <Jymmm> ...again.
[04:14:42] <LoveMHz> I'm trying to stick to a single system nowadays.
[04:15:00] <Jymmm> vmware likes to fuck their customers anymore.
[04:17:06] <XXCoder> "For virtual hardware version 9 (vSphere 5.1) and 10 (vSphere 5.5 Update 1) virtual machines, the default VRAM size is 96MB, and you can configure a maximum size of 512MB."
[04:17:08] <XXCoder> interesting
[04:17:29] <LoveMHz> Workstation goes up to 2GB
[04:17:57] <Jymmm> Did an OS(x) update/upgrade, go to start the VM and got a single dialog of "Vmware is not supported in this version" and an "OK" button which just complete shut down vmware. Basically leaving *ALL* of my VM's in a highjacked/ransome state
[04:17:57] <XXCoder> paid version I guess
[04:18:26] <Jymmm> NEVER FUCKING AGAIN
[04:19:10] <Jymmm> pay us (again) to get your VM's back... FUCK THAT SHIT!!
[04:19:14] <LoveMHz> Random licenses issues? Have you ever messed around with FPGAs?
[04:20:31] <Jymmm> There is a HUGE difference with incompatibility and "Not supported [OK]"
[04:21:29] <Jymmm> You don't leave your customers to hang like that.
[04:22:10] <Jymmm> </end rant (for now)
[04:23:17] <LoveMHz> It just pisses me off that there's no decent way to share a GPU across a VM, or the fact that Autodesk will probably never a Linux version even though it's the most requested feature.
[04:26:36] <Jymmm> Well, request the GPU feature in #vbox
[04:27:10] <LoveMHz> I'm sure they get enough requests
[04:28:10] <LoveMHz> I'm half tempted to buy the Razer Core and see if I can't do GPU passthrough
[04:29:43] <XXCoder> good luck. few times I asked I got slapped bad with "256 mb is enough forever till end of time and behind"
[04:30:22] <LoveMHz> I wonder why it's limited to 256mb, seems like a soft limit
[04:39:52] <archivist> I dont think you lot realise the sharing problem with a gpu
[04:40:56] <LoveMHz> No, I do and I've spent a lot of time researching it.
[04:41:14] <XXCoder> if I recall right, vmbox dont use gpu (not in normal sense) it uses regular ram to store gpu memory in, and uses cpu for gpu ops, unless passthough is used
[04:41:47] <archivist> reload a gpu on every context switch is not funny
[04:42:16] <archivist> 10 gals into a pint pot does not go
[04:43:06] <LoveMHz> the point is vbox refuses to increase the artifical limit because it does not increase performance, even though it would increase compatibility
[04:43:56] <LoveMHz> and then you have nvidia who refuses to work along side anything that shares GPU resources as they would just rather sale you on their grid platform
[04:57:18] <XXCoder> man I love this channel https://www.youtube.com/watch?v=Yo6JI_bzUzo
[05:02:47] <Jymmm> XXCoder: nice straight forward tutorial
[05:02:55] <XXCoder> yeah
[05:03:27] <Jymmm> it always KILLS me to use (or even hink about using) resistors with leds
[05:03:30] <XXCoder> I love how he made cnc out of utter crap stuff. heh
[05:04:04] <Jymmm> think*
[05:04:13] <Jymmm> so much power loss
[05:04:17] <XXCoder> why?
[05:04:44] <XXCoder> ahh yeah
[05:05:04] <XXCoder> to bad there is no lossless, or in least much less lossy method
[05:05:19] <Jymmm> Well, if you look at led strips, it's three SMD leds + a resistor. If you wanted to use a battery or solar , that's a LOT of loss plus heat generated.
[05:05:59] <Jymmm> Well, there sorta is, LEDs are "current driven" not voltage driven.
[05:06:52] <Jymmm> You can using something like an LM317 as a current regulator/limiter, it's in the amp notes of the datasheet
[05:07:04] <Jymmm> s/amp/app/
[05:07:36] <Jymmm> but the LM317 is a hog, would use a different regulator
[05:08:59] <XXCoder> too bad that we dont have TINY current regulators
[05:09:06] <XXCoder> so its more effecient
[05:09:18] <Jymmm> We do, I'm trying to find it now
[05:19:23] <XXCoder> is 40mm fan designb all standard or?
[05:21:32] <jthornton> morning
[05:21:40] <XXCoder> hey jt
[05:21:46] <XXCoder> printing 123 blocks holder hgegh
[05:21:49] <XXCoder> heh
[05:22:06] <jthornton> I wonder how my fan duct came out
[05:22:09] <XXCoder> looks like 32mm is standard hole to hole distance. nice.
[05:22:18] <XXCoder> pics or its ugly print
[05:22:36] <jthornton> could be both lol
[05:22:57] <jthornton> for a 40mm fan?
[05:22:59] <XXCoder> don't know. I can imange so much uglyness lol
[05:23:31] <Jymmm> XXCoder: cant find the link atm =(
[05:23:37] <XXCoder> aw ok
[05:23:41] <XXCoder> jt yeah
[05:24:07] <jthornton> I think that is the bolt circle I measured yesterday on a 40mm fan
[05:24:37] <XXCoder> ok
[05:24:44] <XXCoder> https://www.thingiverse.com/thing:1236978
[05:24:59] <Jymmm> XXCoder: it was off a video I watched, and I cna't recal the context, and browser hostory in FF sucks
[05:25:21] <jthornton> yea I saw them the other day
[05:26:28] <XXCoder> looong print
[05:26:40] <XXCoder> 10% infillm 2 paramters yet...
[05:29:40] <bnz> hey i have a question about coolant pumps and such.. i have a pump that works a bit too well, i.e. it pumps too much coolant for my liking, i would like to be able to use the same pump for mist and flood.. is this how its normally done? to do what i want i would have to have 2 pam settings, one for flood and for mist, (mist will also need a fan turned on)
[05:29:40] <bnz> as far as i can tell coolant uses a on/off signal not a pwm signal.. or can i route the signals thru some module/net to get what i want.
[05:30:14] <bnz> pam =pwm…. damn autocorrect..
[05:30:53] <archivist> often there are valves and reducers
[05:31:29] <bnz> agh i see so the pump just goes full tilt and the size of the hole sets the flow rate..
[05:32:06] <jthornton> that's what I have on all my machines lockline with ball vavles
[05:32:19] <jthornton> valves even
[05:33:11] <bnz> so if i don't want to load up the little pump with a valve i guess i will have to route that signal thru a slider on a custom gui which is how i was doing it previously
[05:34:12] <bnz> and some classic PLC Ladder magic to go with it.
[05:34:47] <jthornton> if it is a centrifugal slowing the flow unloads the motor
[05:35:25] <bnz> oh so the sound i hear is the motor free revving basically
[05:36:36] <bnz> i guess once the water amongst the vanes is up to pressure its just swirling the water around...
[05:36:46] <jthornton> dunno what sound your hearing but a centrifugal pump draws less amps as you close down the output because it is not working as hard
[05:36:57] <jthornton> yea
[05:37:39] <bnz> i guess once the water amongst the vanes is up to pressure its just swirling the water around...
[05:37:42] <bnz> oops
[05:37:46] <bnz> hmm so i maybe a ball valve might be the go……
[05:38:26] <jthornton> if you really want to boost the pressure connect a 10x8 to a 6x4 and watch the pressure gauge go up
[05:40:07] <bnz> i just like the ability to adjust the amount of coolant that flows just so i can limit how much is landing on the doors blocking my vision of whats going on..
[05:40:38] <jthornton> right the normal way is a ball valve on the outlet
[05:41:44] <bnz> ahhh there i go again making stuff before asking the question… i guess i didn't have to wire up 4 PWMGENs to the motor controllers and the mosfets after all.
[05:42:33] <bnz> i think i might need some custom firmware sometime soon.. its really starting to bug me all the unused signals that i can't use…
[05:43:21] <bnz> i;m not running short on IO's yet but it just sets off something in the back of me head that says you can do better than this...
[06:24:40] <JT-Shop> 3
[06:24:50] <XXCoder> hey jt
[06:28:31] <JT-Shop> must have bumped the keyboard, print came out good on the outside and some strings on the inside
[06:28:44] <XXCoder> strange
[06:30:43] <XXCoder> hmm
[06:30:52] <XXCoder> what grease or wax is recommanded for 608
[06:31:33] <JT-Shop> http://gnipsel.com/images/prusa-i3-clone/40mm%20fan%20housing%2001.jpg
[06:31:38] <JT-Shop> http://gnipsel.com/images/prusa-i3-clone/40mm%20fan%20housing%2002.jpg
[06:31:46] <JT-Shop> 608 ball bearing?
[06:31:55] <XXCoder> yeah
[06:32:19] <XXCoder> not bad, that. how is it mounted?
[06:32:26] <JT-Shop> hmm I've never greased one... I'd bet there is some special bearing grease
[06:32:37] <JT-Shop> that is a prototype no mount yet
[06:32:53] <XXCoder> whats other 2 part for?
[06:34:34] <JT-Shop> test parts 50mm tower and some other thing
[06:34:48] <XXCoder> print quality looks much nicer
[06:34:58] <XXCoder> I guess you made some more changes?
[06:36:40] <jthornton> unchanges really
[06:36:54] <XXCoder> huh?
[06:37:41] <XXCoder> https://www.thingiverse.com/thing:1441156 HMM
[06:37:45] <XXCoder> I do want a probe...
[06:37:53] <XXCoder> oh yeah
[06:38:02] <XXCoder> I finally weatherproofed my filiment boxes
[06:38:17] <XXCoder> used door foam strips heh
[06:39:02] <jthornton> I was slowing some things down but returned them to the previous settings
[06:39:58] <XXCoder> heh setting acceration for E to just 1000 made a HUGE differenmce
[06:41:03] <XXCoder> hmm
[06:41:05] <XXCoder> https://www.thingiverse.com/thing:1441156
[06:41:10] <XXCoder> I dunno about its interior
[06:41:14] <XXCoder> wires and rods
[06:41:20] <XXCoder> dont look precise enough
[06:42:27] <jthornton> I think I set the accel to 1000 but I can check
[06:43:27] <XXCoder> I have been favoring this s far https://www.thingiverse.com/thing:721620
[06:43:36] <XXCoder> better design. though one issue is its too tall
[06:43:43] <jthornton> well the seemecnc is down
[06:44:13] <XXCoder> you use that to configure your machine?
[06:44:16] <jthornton> I gave up building one and just bought one
[06:44:29] <XXCoder> how expensive?
[06:44:49] <XXCoder> my biggest issue is limited height. tool tip to bottom is 3 inches lol
[06:44:57] <jthornton> not bad let me see if I can find the link
[06:45:07] <jthornton> this is pretty short one
[06:45:26] <jthornton> yea that is pretty limited Z
[06:45:30] <XXCoder> maybe just use NC switches
[06:45:57] <XXCoder> reprap tatics on cnc router ;)
[06:47:03] <jthornton> http://deepgroove1.com/stainlessprobe/stainlessprobe.htm
[06:48:34] <XXCoder> 175
[06:48:41] <XXCoder> well not too expensibe for good probe
[06:49:33] <jthornton> seems to be ok I had to seat the contacts all the way so the probe would center up

[08:16:36] <Frank_10> Hi
[08:17:42] <JT-i3> Hi Frank_10
[08:18:59] <Frank_10> Yesterday i plugged the 5i25 and 7i76 combo; pncconfig recognized the cards i believe
[08:21:58] <pcw-wichita> I dont think pncconf looks at hardware at all (unless you run the test app)
[08:22:44] <Frank_10> S#/+ lol
[08:22:52] <Frank_10> Im such a noob
[08:23:30] <Frank_10> How can i test the cards are working? I not powering any of them externally yet
[08:23:42] <Frank_10> And jumpers are untouched
[08:24:00] <Frank_10> Ok lets try the tesp app
[08:27:30] <jthornton> Frank_10: you need to supply field power to see the 7i76 pins
[08:28:19] <Frank_10> Ok
[08:28:21] <jthornton> http://www.mesaus.com/info/mesa-pins.txt
[08:28:28] <jthornton> http://www.mesaus.com/info/linuxcnc.html
[08:28:59] <Frank_10> Yes i should re read that; right nlw i have no internet; and im from the cellphone
[08:29:25] <jthornton> ~$ halrun
[08:29:25] <jthornton> halcmd: loadrt hostmot2
[08:29:26] <jthornton> halcmd: loadrt hm2_pci
[08:29:26] <jthornton> halcmd: show pin > pins.txt
[08:29:37] <jthornton> to get a list of all pins do that in a terminal
[08:31:15] <Frank_10> I should supply field power first
[08:31:25] <Frank_10> But i will try that; thanks
[08:31:48] <jthornton> without field power you will get the 5i25 pins only
[08:38:10] <Frank_10> Those commands loadrt give me insmod failed; returned -1
[08:38:19] <Frank_10> I will check the forum
[08:39:13] <JT-i3> just a wag are you running a realtime kernel?
[08:42:36] <Frank_10> Ive installed the debian linuxcnc iso
[08:42:46] <Frank_10> I had to change kernels?
[08:43:26] <Frank_10> I dont want to give you any troubles; im having stupid noob problems that they are for sure on the forum
[08:45:05] <JT-i3> no you should be fine with that, I was just guessing
[09:07:06] <Frank_10> I dont know if its me but i cant find a very similar problem to mine on the forum; only 1 that had a dusty slot on 5i35
[09:07:27] <Frank_10> 5i25 and that fixed it; but mine is new....
[09:22:20] <JT-Shop> Frank_10: is this the line that gave you a problem? loadrt hm2_pci
[09:22:33] <Frank_10> Yes
[09:22:43] <JT-Shop> halcmd: loadrt hm2_pci
[09:22:43] <JT-Shop> insmod: ERROR: could not insert module /usr/realtime-3.4-9-rtai-686-pae/modules/linuxcnc/hm2_pci.ko: No such device
[09:22:43] <JT-Shop> <stdin>:3: exit value: 1
[09:22:43] <JT-Shop> <stdin>:3: insmod for hm2_pci failed, returned -1
[09:23:03] <Frank_10> Ive tried it to unplug the 7i76 but still
[09:23:06] <JT-Shop> I get this error on linux mint with rtai kernel
[09:23:08] <Frank_10> Yep
[09:23:14] <JT-Shop> hmm
[09:23:15] <Frank_10> That same thing
[09:23:31] <Frank_10> Im checking bios if there is some pci config im missing
[09:27:21] <JT-Shop> I wonder if the problem is I don't have a pci card plugged into this computer
[09:29:16] <Frank_10> Looks like ot
[09:29:17] <Frank_10> It
[09:29:35] <Frank_10> But leds go on when machine turns on
[09:29:41] <Frank_10> Red ones
[09:29:44] <Frank_10> Then off again
[09:30:35] <Frank_10> Anything to do with uefi/legacy options of the pci devices?
[09:32:24] <JT-i3> that's above my pay scale sorry (means I have no idea)
[09:33:27] <Frank_10> Lol no prblem
[09:33:36] <Frank_10> Will ask later to pwm
[09:42:26] <JT-Shop> Frank_10: I just verified that the error is because the pci card is not found by putting a pci card in this computer
[09:43:18] <JT-Shop> good thing I popped the hood on this pc it needs cleaning bad
[09:58:07] <mike_LCNC> good morning all
[09:59:22] <mike_LCNC> I am trying to do some servo tuning on the machine I built and cant get it dialed in.
[10:00:14] <mike_LCNC> I was trying manually changing P I and D and watch it on the screen. I have it pretty close but not good enough to attach my roller pinions
[10:00:33] <mike_LCNC> I cannot get Hal-scope to trigger and I get nothing with the scope
[10:00:44] <mike_LCNC> can anyone help please?
[10:00:53] <archivist> you could try the auto tuning thing
[10:02:12] <mike_LCNC> auto-tuning........hmmmmm
[10:02:50] <archivist> but tuning with the load will be different to unloaded
[10:03:46] <archivist> and http://gnipsel.com/linuxcnc/tuning/servo.html
[10:09:10] <mike_LCNC> yeah I read JT's tutorial several times
[10:09:32] <mike_LCNC> problem is I cannot get the hal-scope to behave.
[10:10:23] <Roguish> whats up with your halscope
[10:12:20] <Frank_10> Jt-shop thanks for the help! Now i ve got to figure out why the hell it doesnt...
[10:16:31] <mike_LCNC> I cannot get iot to trigger
[10:16:39] <mike_LCNC> I get nothing really,
[10:16:53] <mike_LCNC> I set it up like JT tutorial and get nothing
[10:17:18] <Roguish> I trigger off a rising velocity signal
[10:17:27] <mike_LCNC> first, how do I get just the XYZ and velocity on screen instead of all the modes?
[10:17:42] <mike_LCNC> using axis
[10:17:44] <Frank_10> Im reading that the 3.3v supply to the board might be off; but everytjing is new and good quality. Seasonic 500w s12 and j1800 gigabyte sighh
[10:18:15] <Roguish> what do you mean all the modes?
[10:20:18] <mike_LCNC> the screen shows G53 and TLO
[10:20:33] <Roguish> turn off the offsets
[10:20:54] <mike_LCNC> thanks
[10:31:37] <mike_LCNC> you trigger on joint.vel.cmd?
[10:31:57] <Roguish> yes.
[10:33:11] <Roguish> i monitor a joint's displacement commanded position and actual (feedback) position. using a simple step input
[10:53:48] <mike_LCNC> is it normal to have my X all in negative value?
[10:54:16] <mike_LCNC> I have to take P to negative value or else I cant get it dialed in
[10:54:44] <Tom_L> not usually
[11:13:47] <gregcnc> mike_lcnc which drive are you using?
[11:25:22] <mike_LCNC> they are krs servo drives
[11:27:33] <mike_LCNC> I can get up to 10 on P before oscilationj
[11:27:52] <mike_LCNC> but cant adjust ff1 to reduce f-error
[11:35:15] <gregcnc> That drive has a lot of settings. are there recommended settings when tuning externally?
[11:35:52] <gregcnc> Or are you tuning in the drive?
[11:40:47] <mike_LCNC> no I am tuning in Linuxcnc
[11:41:23] <mike_LCNC> the encoders are going to the drives and I get out of the drives and connect to encoder imnput on 7i77
[11:42:20] <gregcnc> So are the settings in the drive such that external tuning is effective? i only have experience with dumb amplifiers, but even those had gain, bias that change the settings in Linuxcnc
[11:43:09] <archivist> iirc you have drive in one mode and lcnc in the other when dual loop
[11:44:45] <mike_Linux> The internal drives are suppose to be tuned......
[11:45:18] <archivist> but velocity or position or what
[11:48:04] <mike_Linux> velocity
[11:50:09] <mike_LCNC_1> The docs say to adjust P till it oscilates then back off and adjust ff1 to lower f-error?
[11:51:25] <archivist> I think the people who know are at the linuxcnc fest :)
[11:52:10] <archivist> they are awake I can tell not sure if anyone is watching irc
[11:52:26] <Jymmm> Fest? I thought that was in the summer time?
[11:52:32] <archivist> http://www.archivist.info/cnc/festcam.html
[11:53:59] <gregcnc> this may help understand what you're trying to accomplish http://www.ni.com/product-documentation/2923/en/
[11:58:43] <DGMurdockIII> dose linuxcnc have a good gcode generate
[11:59:16] <archivist> it is not a generator
[11:59:19] <malcom2073> DGMurdockIII: What do you mean a gcode generate? Like simple path generation?
[11:59:27] <DGMurdockIII> like one that could take a scanned picture generate the gcode from that
[11:59:28] <IchGucksLive> hi
[11:59:32] <malcom2073> Ah, no.
[11:59:37] <archivist> there are some addins that can
[11:59:39] <malcom2073> That's not what linuxcnc does
[11:59:47] <malcom2073> Check out inkscape
[12:00:12] <archivist> see the new features/ newname plugin
[12:00:34] <mike_LCNC_1> very frustrating...... lol
[12:01:49] <archivist> DGMurdockIII, http://fernv.github.io/linuxcnc-features/
[12:02:06] <archivist> native cam being the new name
[12:02:23] <mike_LCNC_1> http://micheltrahan.com/image/IMG_0949.JPG
[12:02:25] <malcom2073> Oh nice
[12:02:33] <mike_LCNC_1> http://micheltrahan.com/image/IMG_0950.JPG
[12:02:36] <malcom2073> archivist: Any information on what it actually does, besdies "try some examples" ?
[12:02:59] <mike_LCNC_1> http://micheltrahan.com/image/IMG_0951.JPG
[12:03:09] <mike_LCNC_1> http://micheltrahan.com/image/IMG_0952.JPG
[12:03:15] <archivist> malcom2073, see the youtube video, it does a lot
[12:03:20] <mike_LCNC_1> thats what I am trying to tune
[12:04:00] <malcom2073> archivist: The only videos I've found are like, 3 years old
[12:04:25] <archivist> within the last month
[12:04:38] <malcom2073> Hmm, my google fu is failing me then
[12:04:49] <malcom2073> Ah, found one on page two lol
[12:05:19] <malcom2073> thanks
[12:05:20] <DGMurdockIII> dose the CAM extension for Inkscape work good
[12:05:30] <IchGucksLive> DGMurdockIII: hi this is my advice on image to g-code but it is in german https://www.youtube.com/watch?v=4595Kw9tevo
[12:05:48] <IchGucksLive> DGMurdockIII: incscape makes a DXF
[12:05:52] <IchGucksLive> or a svg
[12:06:17] <IchGucksLive> then y<ou can get g-code on that
[12:06:56] <Jymmm> DIY belt sander https://www.youtube.com/watch?v=4tdSaE663AU
[12:07:23] <IchGucksLive> DGMurdockIII: if you share the pic Image we can help yopu for perfect g-code milling
[12:07:38] <malcom2073> DGMurdockIII: I've had pretty good luck with it, it's a bit of a hassle to install and deal with, but it works. Exporting to dxf is often a better option, then using a dxf to gcode converter can work better
[12:08:11] <DGMurdockIII> beside getting from a picture or scanned hand drawn image what would bee best free gcode generator
[12:08:30] <IchGucksLive> depends on part
[12:08:39] <IchGucksLive> there are great in LCNC
[12:08:46] <IchGucksLive> also alot of free out
[12:09:05] <IchGucksLive> and pro onlies like Fusion360
[12:10:26] <DGMurdockIII> ok
[12:10:45] <IchGucksLive> what OS are you on
[12:11:18] <DGMurdockIII> windows
[12:11:19] <archivist> DGMurdockIII, this https://forum.linuxcnc.org/forum/40-subroutines-and-ngcgui/31659-nativecam-is-features-renamed
[12:11:59] <archivist> 2 weeks ago https://www.youtube.com/channel/UCjOe4VxKL86HyVrshTmiUBQ
[12:12:02] <DGMurdockIII> OpenSCAM ?
[12:12:15] <IchGucksLive> Heekscad
[12:12:18] <archivist> openscam is renamed as well
[12:12:20] <IchGucksLive> Freecad
[12:12:22] <mike_LCNC_1> IF I have f-error when moving axis, I adjust ff1? That is cruise mode?
[12:12:53] <IchGucksLive> DGMurdockIII: use fusion360
[12:13:02] <IchGucksLive> best on hobbyist on windows
[12:13:06] * Jymmm wants that table saw!!!
[12:13:09] <archivist> openscam is now http://camotics.org/ and is a viewer no a creator
[12:13:38] <IchGucksLive> archivist that is cool and getting better by the momnth
[12:13:53] <IchGucksLive> the demo now already have G41/G42
[12:14:23] <gregcnc> safety moccasins
[12:14:30] <IchGucksLive> DGMurdockIII: for simple stuff Qcad
[12:16:00] <DGMurdockIII> i use mach3
[12:16:11] <DGMurdockIII> to control my cnc
[12:16:16] <IchGucksLive> DGMurdockIII: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Simple_LinuxCNC_G-Code_Generators
[12:16:25] <IchGucksLive> mach3 is crap
[12:16:39] <IchGucksLive> use editnc
[12:17:32] <IchGucksLive> DGMurdockIII: Why in this world are youas a WIN user asking on a opensource Linux channel for hewlp
[12:18:06] <IchGucksLive> there are so many microsoft freek channels to help you
[12:18:17] <archivist> might be getting ready to upgrade
[12:18:20] <DGMurdockIII> only cnc channel i could find thats active
[12:18:53] <IchGucksLive> agree
[12:19:20] <gregcnc> Oh I saw the native cam and wondered , now I know it was features
[12:20:15] <archivist> new or additional maintainer I see
[12:20:17] <IchGucksLive> DGMurdockIII: go for fusion360 best you can do
[12:20:52] <IchGucksLive> archivist camotics?
[12:20:56] <DGMurdockIII> ok
[12:21:17] <archivist> IchGucksLive, new name for openscam
[12:21:18] <IchGucksLive> V-curve for picturers
[12:29:08] <IchGucksLive> DGMurdockIII: arcam is the same and you can go free for a try
[12:29:36] <DGMurdockIII> ok
[12:42:41] <mike_LCNC_1> Can someone help me with this? http://micheltrahan.com/image/IMG_0954.JPG
[12:45:34] <Frank_10> Guys any ideas why my 5i25 cant be found on pci
[12:46:06] <Frank_10> How can i test it on my windows pc?
[12:48:23] <Kevin`> could the firmware on it be messed up?
[12:53:45] <Frank_10> i bought it i combo with 7i76
[12:54:00] <Frank_10> u thinki should reflash?
[12:54:52] <Frank_10> im afraid of killing the board
[12:56:01] <CaptHindsight> Frank_10: how are you trying to discover the 5i25? Using the Linuxcnc ISO to install the complete system or?
[12:56:29] <CaptHindsight> I'm wondering why you mention Windows
[12:58:33] <dioz> when you check in your device manager do you see any unknown devices?
[12:58:40] <cradek> Frank_10: on my system, lspci shows it as: 11:08.0 DPIO module: Device 2718:5125 (rev 01)
[12:59:00] <dioz> lspci if linux
[12:59:23] <Frank_10> to check on my other pc if its the pci port
[12:59:35] <Frank_10> capthindsight
[13:00:15] <Frank_5> on the linuxcnc machine i installed the iso and the board is on the pci port
[13:00:34] <Frank_5> but when i try loadrt hm2_pci it gives me an error
[13:00:47] <CaptHindsight> Frank_5: does it show up when you run lspci?
[13:00:50] <cradek> what do you do and what error do you get?
[13:00:52] <dioz> then open a terminal and type lspci
[13:01:38] <Frank_5> "could not insert module bla bla no such device" exit value 1 insmod for hm2_pci failed
[13:01:45] <Frank_5> ok brb
[13:01:55] <Frank_5> ill try that
[13:02:02] <dioz> you "blah blah'd" over the most important part elaine
[13:02:08] <dioz> yada yada'd i guess
[13:02:30] <Frank_5> hehehe
[13:03:03] <dioz> you're wondering if firstly your machine is recognizing the card is present
[13:03:04] <dioz> i'm assuming
[13:03:06] <Frank_5> ERROr could not insert module /isr/realtime 349 rtai /modules/linuxcnc...
[13:03:13] <dioz> you'll need to open a term and lspci
[13:03:16] <dioz> and paste the results
[13:03:20] <Frank_5> red leds go on when turning on
[13:03:24] <Frank_5> ok
[13:04:06] <dioz> then check your syslogs
[13:04:58] <Frank_5> doing it
[13:06:29] <Frank_5> give me a sec i connected internet on the linux pc
[13:10:10] <Frank_10> sigh lan cable bugged out
[13:10:18] <Frank_10> ill upload pic
[13:10:46] <Frank_10> dioz; how exactly o check syslog
[13:10:58] <Frank_10> i put that on terminal and nothing
[13:14:26] <Frank_5> http://imgur.com/3FOxFcB lspci terminal
[13:19:39] <Kevin`> Frank_5: they are normally flashed properly when bought like that, at least enough to be recognized. make sure the jumpers are set right though
[13:25:03] <Frank_5> i will check that too....
[13:33:26] <mike_LCNC_1> changed a setting in the drive and it l;ooks much better.
[13:40:08] <Frank_5> looks like lspci doesnt find the 5i25 either
[13:40:13] <dioz> Frank_10: yah
[13:40:31] <dioz> you can either cat your /etc/var/log/syslog files
[13:40:37] <dioz> or use whatever editor you're savy with
[13:40:42] <dioz> idk much about the linuxcnc distro
[13:40:54] <dioz> editor, pico, vi, cat, tail, etc.
[13:41:16] <Frank_5> what should i check on syslog files
[13:41:30] <dioz> what 5i25 card is it?
[13:41:54] <dioz> mesa 5i25
[13:42:03] <dioz> idk what those look like but i know linux
[13:42:19] <Frank_10> yes 5i25
[13:44:28] <dioz> try a different pci slot?
[13:44:40] <dioz> try it on another board
[13:45:10] <Frank_10> i will try on another pc..thanks thou
[14:19:41] <JT-Shop> Frank_10: lspci shows a 6i25 as PCI bridge: Intel Corporation 8 Series/C220 Series Chipset Family PCI Express Root Port #5 (rev d5)
[14:22:28] <Frank_5> when i put lspci on terminal it doesnt show up any pci bridge,
[14:22:32] <Frank_5> http://imgur.com/3FOxFcB
[14:29:50] <mmachines> Looking at adding the Mesa 7I75 breakout to access the other port of the 6I25
[14:30:28] <mmachines> will need another DB25 cable
[14:30:34] <tiwake> sautéed mushrooms, eggs, jalapeños... seasoned with some garlic, pepper, paprika, and a wee bit of taco seasoning... rolled up in a burrito with some cheese and BBQ sauce in it
[14:30:45] <tiwake> no idea what it is called, but it tastes amazing
[14:31:21] <mmachines> Mesa sells a 10' DB25 cable $12.50 - then you can find "premium" shielded cables elsewhere
[14:31:36] <mmachines> but is there really any difference? or are they all shielded?
[14:32:19] <CaptHindsight> not all cables are shielded and not all cables have all the connections
[14:33:26] <CaptHindsight> you wast IEEE-1284 compliant cables
[14:33:31] <CaptHindsight> wast/want
[14:35:16] <CaptHindsight> lower cost db25 printer cables will not have all the connects from end to end
[14:35:41] <mmachines> OK thanks
[14:36:30] <mmachines> the Amphenol cable on amazon is 2x the price of the Mesa cable
[14:37:42] <JT-Shop> mmachines: the cable has to be a DB25M to DB25M IEEE 1284 compliant parallel port
[14:37:43] <CaptHindsight> I'll be happy to sell you one for 10-100x either price with magic beans
[14:37:52] <JT-Shop> http://mesaus.com/index.php?route=product/product&path=71&product_id=59
[14:38:02] <mmachines> great!
[14:38:05] <JT-Shop> you also need this http://mesaus.com/index.php?route=product/product&path=71&product_id=70
[14:39:01] <mmachines> right thanks
[14:39:42] <Frank_5> anyone knows how to test a 5i25 on windows?
[14:40:10] <CaptHindsight> Frank_5: run the LiveCD on the windos pc for testing
[14:40:35] <mike_LCNC_1> can someone help with following error on a slave axis?
[14:40:44] <CaptHindsight> don't install, just run it
[14:40:59] <Frank_5> i dont know what to hope, if the mobo is bad or the 5i25
[15:02:34] <Frank_5> weird enough, now the motherboard wont receive the lan comunication, the cable just does nothing, and i connected it to this computer and it works, is it posible that a 220v cable (no load) is interfering (noise) with the motherboard?
[15:50:52] <JT-Shop> Frank_
[15:51:25] <JT-Shop> Frank_10: this pc had 4 other pci bridges when no mesa card was plugged in or anything else
[16:02:25] <mmachines> JT-Shop: The Mesa 7I75 itself isn't available from mesaus.com is it? Didn't see it on the website.
[16:08:30] <mike_LCNC_1> JT:
[16:08:45] <mike_LCNC_1> Can I ask a few servo tuning questions?
[16:17:20] <gregcnc> mike_lcnc_1 did you read the NI link I gave?
[16:27:07] <MacGalempsy> odele!
[16:27:21] <Frank_5> jt-Shop what do you mean by that? that i should have seen a pci bringe on lspci? therefore thinking that the mobo is bad
[16:29:10] <MacGalempsy> estoy en la fiesta de la cerveza del springdale!
[16:29:35] <MacGalempsy> vamanos a la fiesta!
[16:29:39] <Deejay> gn8
[16:31:03] <Jymmm> Anyone suggest a car battery brand?
[16:31:23] <jdh> Acme. good enough for the coyote
[16:31:41] <sync> optima
[16:31:43] <gregcnc> optima
[16:31:46] <Jymmm> JT-Shop: Is that 1-800-BEEp-BEEP ?
[16:31:56] <Jymmm> jdh: ^^^
[16:32:22] <jdh> I go to the auto part store, get the most cca that fits
[16:32:22] <Jymmm> Why optima? (just curious)
[16:32:29] <sync> why not
[16:32:46] <Jymmm> $48 at wally world is why not =)
[16:32:47] <gregcnc> good capacity, current, and life
[16:33:12] <jdh> $48 isn't a car battery
[16:33:22] <gregcnc> but if cheap, just get whatever and a spare
[16:34:21] <Jymmm> gregcnc: More like bang for the buck, auto parts store wants from $120 to $190, optima in the $200's
[16:35:03] <gregcnc> depends on what a dead battery will cost you
[16:35:38] <mike_LCNC_1> I am trying to get two servos tuned that share same axis. its not working, I cannot get them in tune, is it possible I am working against the drives in that the encoders go into the drive and out to linuxcnc.
[16:36:14] <gregcnc> that's why i asked about drive tuning before
[16:37:19] <MacGalempsy> jymmm : what kind of battery u need?
[16:39:44] <mike_LCNC_1> Can I just remove the vel cmd wire (7i77) going to the drive then I will see if the servos are tuned by if the dro is moving alot.
[16:39:44] <mike_LCNC_1> no?
[16:41:19] <mike_LCNC_1> that wont work, it will throw a joint follow error cause LCNC is telling to move and it wont.
[16:45:32] <MacGalempsy> tune that 7i77 right
[16:45:59] <MacGalempsy> and you wont have that problem
[16:47:07] <Frank_5> is there a chance that a bad bios is causing problems with a pci legacy slot?
[16:53:39] <Jymmm> MacGalempsy: car battery
[16:54:14] <Jymmm> Frank_5: problems?
[16:54:53] <MacGalempsy> jymmm: sears
[16:57:54] <Jymmm> Doesn't 650 CCA seema bit low for a 4.6L V8 ?
[17:04:27] <Tom_L> JT-Shop, get anywhere with that file?
[17:19:30] <JT-Shop> Tom_L: yes, I'm making it real nice
[17:19:35] <JT-Shop> I work on it in the mornings
[17:20:09] <JT-Shop> the navigation buttons work like you would expect and actually back up one page now
[17:20:59] * JT-Shop was real productive this afternoon and put up 5 Kubota loads of fire wood in the crib
[17:37:20] * JT-Shop wonders why iftop shows twitter
[17:39:37] <Frank_5> jymmm: i cant seem to find the 5i25 when i plug it in my pci port, i think its a bad mobo, i still have to check the card on another computer
[17:40:01] <Frank_5> sorry for the delay lol , im in and out (working)
[17:46:33] <JT-Shop> Frank_5: the 5i25 has the firmware loaded just before I ship so at that point I know it works, I suspect the motherboard if you don't see and bridges with lspci
[17:56:52] <Frank_10> yep.. a bummer i bought a j1800 new
[17:57:13] <Frank_10> idk why not it doesnt recognize ethernet either
[17:57:53] <Tom_L> JT-Shop how are you testing it?
[18:02:14] <JT-Shop> running it
[18:02:50] <Tom_L> i looked at it briefly
[18:03:35] <JT-Shop> http://gnipsel.com/logs/index.html
[18:03:47] <JT-Shop> this shows the back buttons working as you expect
[18:04:12] <JT-Shop> it's not complicated to fix the order of the files from newest to oldest
[18:04:34] <Tom_L> i thought the back buttons worked
[18:04:38] <JT-Shop> might get fancy and show year, month then days of that month lol
[18:05:03] <Tom_L> i don't look at mine that often..
[18:05:08] <nubcake> hi
[18:05:09] <JT-Shop> no they take you back to the main page then you have navigate to the linuxcnc page
[18:05:28] <Tom_L> i did move all the old logs out the other day
[18:06:01] <Tom_L> zlog
[18:06:28] <Tom_L> never noticed that before
[18:06:45] <JT-Shop> see if you hit back from there you go to irc chat logs
[18:07:02] <Tom_L> yeah
[18:07:05] <JT-Shop> I could make the chat logs page by year
[18:07:21] <JT-Shop> #linuxcnc-2016
[18:07:28] <JT-Shop> #linuxcnc-2015
[18:07:30] <Tom_L> separate folders automatically?
[18:07:30] <JT-Shop> etc
[18:07:35] <JT-Shop> yea
[18:07:53] <Tom_L> i just put everything but 2016 in one folder
[18:07:59] <Tom_L> not many will go there anyway
[18:08:08] <JT-Shop> that's prob fine
[18:08:24] <Tom_L> i had to hand edit all the index.html files though
[18:08:49] <JT-Shop> the logs/index.html?
[18:09:10] <Tom_L> each folder's and the main one
[18:09:20] <Tom_L> since i added the _old directories
[18:09:32] <JT-Shop> can you zip up the linuxcnc and linuxcnc old html files for me in the morning
[18:09:42] <JT-Shop> give me more to work with
[18:09:56] <Tom_L> i can do it right now if you want
[18:10:10] * Tom_L licks the chicken off his fingers
[18:11:58] <Tom_L> you want them all?
[18:12:14] <JT-Shop> yea why not
[18:12:44] <Tom_L> i'll make 2 files, 2016 and the rest
[18:13:40] <JT-Shop> ok
[18:14:16] <Tom_L> rar ok?
[18:16:31] <JT-Shop> does linux understand rar?
[18:16:46] <cradek> there is nonfree unrar in debian
[18:16:56] <JT-Shop> thanks
[18:18:23] <Tom_L> http://tom-itx.no-ip.biz:81/~webpage/cnc/JT-SHOP/
[18:18:41] <Tom_L> logs....rar
[18:19:04] <Tom_L> 40M too much?
[18:19:30] <JT-Shop> looks like unrar comes installed on linux mint
[18:19:38] <JT-Shop> not in the morning it not too much
[18:19:48] <Tom_L> they're both there
[18:20:23] <JT-Shop> I sent myself the link so I can see it down in the beer cave at 5am
[18:20:39] <Tom_L> i'll still be counting sheep
[18:22:54] <JT-Shop> in about 30 minutes I'll be counting elk tenderloin bites
[18:23:15] <KreAture_> elk is too gamey
[18:23:21] <KreAture_> give me a juicy tender cod
[18:23:22] <KreAture_> cow
[18:24:05] <Tom_L> if you wanna break em up by year, feel free but it's not necessary
[18:29:53] <JT-Shop> elk ain't gamey, badly prepared deer is
[18:32:49] <TurBoss> Hello
[18:36:12] <nubcake> night everyone
[18:37:59] <TurBoss> night
[18:41:06] <JT-Shop> goodnight
[18:44:59] * JT-Shop needs to make a tool box for the http://gnipsel.com/images/splitter/splitter-29.jpg
[18:45:27] <JT-Shop> http://gnipsel.com/images/splitter/splitter-28.jpg
[18:54:40] <JT-Shop> time to fire up the barbie
[20:20:52] <MacGalempsy> Pete!
[20:48:56] <BeachBumPete> hey mac
[20:50:07] <bnz> I have (yet another) question.. do i really need 645 steps per mm (0.00155 mm per step) or would i be better off turning down the micro steps to say 4x instead of the 16x i am at ATM.. that would give me 161steps per mm.. that gives me 0.0062mm/step?
[20:51:15] <bnz> my thinking is that i might get better defined steps with lower micro stepping thus giving me better repeatability at the cost of un-needed accuracy
[20:53:34] <bnz> I have Ball screws installed and i am noticing that i can't get it to step exactly 5mm or 100mm its always a little more or a little less. at the moment 100mm=100.8mm and will vary a little 100.6 100.7 100.9 but 100.8 is the most common result, given that i am using a digital vernier to make these readings am i done polishing this turd?
[20:54:24] <bnz> is sub % accuracy acceptable?
[20:58:45] <gregcnc> if that allows you to make parts to tolerance, yes
[21:07:55] <bnz> well i am just not sure what 'tolerances' i need at this point in time :) just wondering if the machine will be better with the micro steps turned down… guess its sort of a feel thing :)
[21:08:54] <jdh> microsteps past 1/2 don't actually give you the resolution you calculate
[21:08:59] <jdh> and you lose torque
[21:09:16] <gregcnc> 1/2 step is 70% torque already
[21:58:19] <Jymmm> Frank_10: try moving it to a different PCI slot and see if that make a difference
[23:02:34] <enleth> bnz: 0.8mm of error on a 100m move looks like a systematic error
[23:05:15] <enleth> bnz: inaccurate steps with a travel of 0.0062mm/step should average out, but you either have a motor/drive/configuration combination that effectively causes *extra* steps to be made, or a slightly unaccurate ballscrew, or a slightly unaccurate transmission if the ballscrew is not directly coupled to the motor
[23:05:52] <enleth> strictly speaking, causes extra steps to be made more often than it causes steps to be missed
[23:06:34] <enleth> bnz: by all means try reducing the microstepping accuracy and measure your distances on several different settings
[23:06:40] <enleth> including no microstepping at all
[23:07:02] <enleth> try different feedrates if you start to notice differences
[23:07:35] <enleth> or maybe it's the ballscrew/transmission
[23:07:38] <enleth> or the calipers
[23:11:53] <bnz> i think it was all me.. :( as sad as that is to admit.. i was doing the calculations wrong.
[23:15:04] <bnz> i stopped trying to do the calc and switched to a successive approximation method. i.e. find two settings that give clear different results i.e. 1mm difference over 100mm then note the steps and halve the difference and keep moving towards my goals.. i now have it down to 100.1mm over 100mm on Y and 49.98mm over 50mm on Z
[23:19:19] <enleth> 100.1mm or 100.10mm? Remember, the trailing zeros indicate measurement precision
[23:20:41] <bnz> 100.01 sorry.. was a typo.. thats the limit of the digital vernier i am using.. i will dig out the dial indicator and see if can get it any better.
[23:20:52] <bnz> but once i get encoders and mount them these problems should go away… i have one at the moment but don't really like my mounting options.. i think i need to replace my motors to ones with double shafts...
[23:20:59] <enleth> you're probably using +/-0.02mm calipers, so 100.10mm is more descriptite, as the measurement tool's precision range is closer to 0.01 than 0.1mm
[23:21:07] <enleth> oh, ok
[23:21:18] <enleth> the above still stands, though
[23:21:31] <enleth> *descriptive
[23:21:32] <bnz> yes you speak the truth :)
[23:22:38] <enleth> as for encoders, if the motors have the rear end of the shaft visible, you can even use glue
[23:22:47] <enleth> it's not like encoders need any kind of real torque
[23:23:13] <bnz> oh i was tempted to super glue a shaft on the end..
[23:23:28] <enleth> for the encoder? go for it
[23:23:52] <enleth> just make sure you don't squeeze the glue into the bearing
[23:24:37] <enleth> drilling a small hole in situ to accept a centering nub and excess glue is a possibility as well
[23:24:42] <bnz> i have some 5mm drill rod so i might do that for X axis. i was thinking of drilling a hole at an angle in the face of the rod. to allow the glue to escape.
[23:25:23] <bnz> my shafts have a centre hole in the end so i might make a nub on the end of the shaft to align with that.
[23:27:19] <enleth> that should be fine
[23:27:33] <enleth> make a nub shorter than the hole is deep, dab a little glue on
[23:28:05] <enleth> just don't try pulling the motor apart to work on the shaft ends unless you have experience in disassembling hybrid steppers properly
[23:28:17] <bnz> that will be fine for both X and Y.. but Z is a little bit of a problem..
[23:28:25] <enleth> it's very easy to kill them by demagnetizing the rotor
[23:28:50] <enleth> letting it so much as touch the stator can do it
[23:29:28] <bnz> oh i have a guy at work that pulls our steppers apart to machine them if i have to he will be employed for that task he made a jig up to stop all that happening
[23:29:28] <enleth> and it's hard to take the end cap off without letting the rotor sway to the side and touch the stator
[23:30:01] <bnz> mind you his jig is set for double shaft motors so it might need upgrading to suit my motor
[23:30:08] <enleth> ok, you're lucky to have that guy at hand
[23:30:52] <bnz> yes he has been a great source of information and assistance.. he is more excited about my mill than me :)
[23:30:56] <enleth> if the rear end has a proper center hole, he might be able to use a very thin long center at the rear
[23:31:41] <bnz> i show him a few of my better jobs. he likes the results i have been getting..
[23:32:16] <bnz> yeah might need to make a mandrel for the tailstock on a lathe..
[23:32:20] <enleth> of course, if you can pull the rotor out properly, you can put it in a lathe, drill a longer 3-4mm dia hole, 10-15mm deep, and loctite in a proper shaft extension
[23:32:43] <enleth> then turn it true
[23:33:06] <enleth> or even freeze it and shrink fit in
[23:33:07] <bnz> hmm thats tempting
[23:33:41] <enleth> heating the rotor wouldn't be a wise idea, but for a light shrink fit, just freezing the extension should do
[23:34:39] <bnz> yeah the insulation on the coils might not enjoy it.
[23:34:43] <enleth> but loctite will be plenty enough if you remeber to not use that side to drive loads
[23:36:05] <bnz> yeah i might give the glue and a nub a go and see how long that lasts..
[23:36:28] <bnz> my only fear is that if i knock the shaft it will break my encoder disc
[23:37:20] <bnz> the little cover on the encoder should provide some support.
[23:38:54] <enleth> up to you, but if you have access to a professional and some time, maybe try making a deeper hole, that will not break off for sure
[23:40:07] <enleth> just a snug clearance fit and some loctite/superglue, without going overbroad with press/interference fits for a damn encoder
[23:40:44] <enleth> even that will machine just fine, especially if the extension is aluminum
[23:41:09] <enleth> do you watch clickspring videos?
[23:43:56] <bnz> i watch all sorts of videos.. i had a job where i spend 4.5days a week watching youtube and doing foreign orders :)
[23:44:38] <bnz> i do like NYCNC that guy delivers the content in a really relatable way even if it is a bit of a sales pitch for tormach..
[23:44:51] <enleth> bnz: I can't find the right video now, but I'm sure he did more than one turning operation on a part that was just loctited into a snug fit hole in another part, with the latter one being actually clamped in the lathe chuck
[23:45:15] <enleth> and one of those was something in the 8-10mm diameter range
[23:45:36] <bnz> I have their Quick release Chuck system, which i supplemented with chinese clones.. but i did but a fair bit of their stuff to start with.
[23:45:49] <enleth> so gluing in a shaft extension and then turning it down to size for concentricity seems safe and doable
[23:46:38] <bnz> hmm wouldn't have thought it would survive me turing it.. but yeah might have to talk to dave during the week..
[23:47:14] <enleth> just use something soft for the extension
[23:47:41] <bnz> he is happy to do anything for me.. but if he feels i can do it, with his equipment and supervision he prefers to teach me.. and i am happy to learn.. :)000
[23:48:01] <bnz> might have to roll out to his place next weekend...
[23:48:17] <enleth> as for NYCCNC - personally I don't really like the way John "acts" and talks, his constant smile just, well... weirds me out
[23:48:20] <enleth> I have no idea why
[23:48:51] <enleth> but I have the same problem with Dale from Metal Tips And Tricks
[23:49:37] <enleth> both of them just smile all the time while talking in a way that's unnerving to me
[23:50:32] <enleth> if someone started talking to me in person like that, I think I'd find a very good excuse to abscond ASAP
[23:51:27] <bnz> heheheh yeah i don't watch for his facial expressions its not sex its a tooling video :p
[23:51:47] <bnz> but yes i get what you are saying.
[23:52:30] <bnz> what i really hate is how some guys just dribble on for ages then only for a short period of time on what the video was really about.. or was meant to be about.
[23:53:11] <bnz> but now i need to go to the hardware to get a 3mm tapp. i can't find mine and need to mount my limit switches..
[23:53:31] <bnz> bbs
