[00:28:48] <hazzy-lab> flyback: that is pretty neat
[00:36:31] <Wolf__> hmm, how much head and water flow do I need to do that? =)
[00:52:07] <flyback> Wolf__, depends on the scale
[00:52:40] <Wolf__> 2-3hp worth of 3phase 220? =)
[00:53:39] <flyback> you will need an exciter
[00:53:56] <flyback> small generator or something or charged caps to get the field initially energized
[00:54:03] <flyback> and you need to disconnect the load before it spins up
[00:54:21] <flyback> otherwise induction motors as generators are fine
[00:54:35] <Wolf__> so, not as simple as just spinning a 3phase motor is it
[00:54:55] <flyback> well almost it's just it won't self generate so you need to energize the field
[00:55:02] <flyback> could be a battery and a cheap inverter even
[00:55:18] <flyback> once it's charged it stays charged unless overloaded or stopped
[00:55:57] <Wolf__> ok
[00:56:09] <flyback> it's not hard
[00:56:11] <flyback> don't panic
[00:56:23] <flyback> commercial generators have the same issue
[00:56:33] <flyback> so they had these little motor looking things on the side
[00:56:36] <flyback> called exciters

[00:57:19] <Wolf__> cool
[00:57:52] -!- laminae has joined #linuxcnc
[00:58:00] <flyback> it would be a perm magnet dc motor or such to get the magnetic field going
[00:58:13] <flyback> since it's only used during stop/starts, the brush life is not a concern
[00:58:40] <flyback> some don't use brushes and have spinning diodes
[00:58:43] <flyback> https://tcluk.net
[00:59:46] <Wolf__> ahh, learn something new every day
[01:00:16] <flyback> http://www.jamestownbpu.com
[01:00:25] <flyback> you can also use excited voltage to regulate output
[01:00:30] <flyback> that's what car alternators use
[01:00:43] <Wolf__> yeah

[01:02:48] <flyback> https://www.quora.com
[01:03:37] <flyback> this is a simple problem for low power
[01:03:41] -!- laminae_ has joined #linuxcnc
[01:03:53] <flyback> you could probably use a $20 car inverter and a battery to initially energize
[01:04:02] <flyback> actually since it needs a dc voltage even easier
[01:04:05] <flyback> just a boost converter

[01:05:47] <flyback> pumps as turbines aren't the most efficient but they are so cheap and easy to source it doesn't matter that much

[01:07:14] <Wolf__> I have a spring fed pond, thats where my interest starts =)
[01:07:43] <hazzy-lab> flyback: the exciters I'm used to weigh about 40tons, but that's still tiny compared to the generators at 600tons :D
[01:07:53] <flyback> yep
[01:08:01] -!- laminae has joined #linuxcnc
[01:08:05] <flyback> hazzy-dev, have you seen them dry ice blast them
[01:08:08] <fragalot> hi
[01:08:18] <hazzy-lab> flyback: No
[01:09:26] -!- laminae_ has joined #linuxcnc
[01:09:39] <flyback> lemme find some
[01:10:21] <flyback> https://www.youtube.com
[01:11:02] <hazzy-lab> I have watched them spin test them, which is pretty impressive. I was surprised that they needed to be cooled just for spinning, but the the air friction is significant enough to heat them up a good bit
[01:11:09] -!- RussellB2819 has quit [Ping timeout: 264 seconds]
[01:11:18] <flyback> well the loads also heat them up
[01:11:34] <flyback> even my little 1400w gas generator I put a big fan on during an outage
[01:11:40] <flyback> went from 400f TO 260
[01:12:02] -!- laminae_ has quit [Client Quit]
[01:12:25] -!- lamina has joined #linuxcnc
[01:12:33] <flyback> LOW PRESSURES only remove dirt and grease
[01:12:39] <flyback> high pressure will remove lead paint
[01:12:52] <flyback> which is nice because you only have lead paint to vacume up and take to disposal plant
[01:12:52] <hazzy-lab> flyback: there is no current during the spin test, it is just the rotor
[01:12:58] <flyback> if you used sand them you have leaded sand
[01:13:05] <flyback> big mess
[01:13:12] -!- lamina has quit [Client Quit]
[01:13:29] <flyback> that's what destroyed that russian power plant
[01:13:36] <hazzy-lab> that is neat, also the dry ice just sublimates and does not leave any residue
[01:13:39] <flyback> weld imbalanced and they ignored it
[01:13:42] <flyback> correct
[01:14:05] -!- laminae_ has joined #linuxcnc
[01:17:17] <flyback> wolf if you only want a few dozen watts or have very small flow, then a perm magnet generator might be better
[01:18:41] <hazzy-lab> talking about imbalance: one the the siemens generators failed recently on initial start up. tuned out they had used propane torches (instead of induction) to heat the ends of the shaft to plug the inspection bore and the combustion gases had condensed in it and threw it out of balance. it was a pretty major crash, destroyed the bearings mounts and did some damage to the turbine
[01:18:58] <Wolf__> yeah, tie it in to a battery bank to supplement a solar system
[01:19:47] <hazzy-lab> flyback: would an auto alternator be worth anything for a small hydro plant, or would it be too inefficient?
[01:20:14] <flyback> probably not as is nheeds high rpm
[01:21:30] <hazzy-lab> yeah, true

[01:24:00] <laminae_> Hey guys, have some first time setup issues, after installing preemptive kernal for 7i76e and using a known pncconfig i encounter "unable to retrieve mac address" i have moved the w3 jumper up and edited the .hal file to 10.10.10.10 also set ethernet to static 10.10.10.1
[01:24:20] <hazzy-lab> flyback: well, induction is RPM sensitive it you want 60Hz output :)
[01:24:39] <laminae_> I'm power tb1 and tb3 also, only illuminated led is the power led
[01:24:44] <Wolf__> true, for a small home setup I have been thinking a system tied to a battery bank like the power wall would be nice
[01:24:48] <laminae_> i'm powering*

[02:05:08] <Laminae_> hmm
[02:06:00] <Laminae_> Could anyone verify from network folder if this looks correct for static ip to my 7i76e?:
[02:06:22] <Laminae_> auto lo eth0
[02:06:45] <Laminae_> iface lo inet loopback
[02:07:12] <Laminae_> Whoops, copied from incorrect window
[02:07:41] <Laminae_> auto lo enp3s0
[02:08:06] <Laminae_> iface enp3s0 inet static
[02:08:12] <Laminae_> address 10.10.10.1
[02:08:18] <Laminae_> netmask 255.255.255.0
[02:08:58] <Laminae_> If i pint 10.10.10.10 it does get a reply but i'm wondering if there might be some other communication issue?
[02:09:38] <Wolf__> board firmware?
[02:10:32] <Laminae_> Is there a way to check without connecting?
[02:10:45] <Laminae_> I'm willing to bet i'm just doing something really stupid
[02:10:52] <Laminae_> I've never setup linuxcnc before
[02:11:18] <Wolf__> there is a set of directions somewhere
[02:11:57] <Laminae_> I've follow several of them including ones for the specific pc i am using
[02:12:14] <Laminae_> I tried different isos to be certain as well
[02:12:20] <Laminae_> currently using the one from this https://forum.linuxcnc.org
[02:14:03] <Wolf__> dunno, the few guys that know the mesa stuff inside out are usually on day/evening central time USA
[02:14:38] <hazzy-lab> Laminae_: I don't know anything about the ethernet cards, but looking at a config I have for one it looks like the IP is 10.10.10.10
[02:14:39] <hazzy-lab> http://dpaste.com
[02:15:31] <Laminae_> Yeah, my .hal file does match that
[02:15:48] <hazzy-lab> ok, that is all the help I can be, sorry :)
[02:15:55] <Laminae_> Thanks!
[02:16:06] <Laminae_> Just a sanity check is nice at this point haha
[02:16:23] <hazzy-lab> haha, yes
[02:16:31] <Wolf__> some day I need to get a ether thingy to try out
[02:16:44] * hazzy-lab thinks the same
[02:16:59] <Laminae_> I'm really regretting it at this point >.>
[02:17:06] <Laminae_> Been mesing with this for many hours
[02:19:03] <Laminae_> I'm guessing this isn't really helpful but just in case on of you guys can glean more from it, this is the dump http://dpaste.com
[02:19:38] <Laminae_> Line 29 being the cause
[02:21:27] <Laminae_> If i run: Ip addr show
[02:21:30] <Laminae_> From terminal
[02:21:36] <Laminae_> I get this: http://dpaste.com
[02:25:56] -!- fkz has joined #linuxcnc
[02:26:19] <rmu|w> Laminae_: you have assigned 10.10.10.10 to your ethernet interface
[02:26:53] <rmu|w> Laminae_: so if you ping 10.10.10.10 what will happen is you effectivly ping the loopback
[02:27:09] <Laminae_> Ah, i figured i did something stupid
[02:27:25] -!- fkz has quit [Remote host closed the connection]
[02:27:39] <Laminae_> If i use eth0 i get an error, and i thought i google foo'ed my way through, clearly not
[02:27:54] <rmu|w> it is called enp3s0
[02:30:12] <Laminae_> In that case, what should i be using as the name for my ethernet?
[02:30:13] <rmu|w> you could try "ifconfig enp3s0 10.10.10.1/24" and then ping 10.10.10.10
[02:30:39] <rmu|w> the "ip neigh | grep 10.10.10.10" should show the mac addr of the mesa card
[02:30:41] <Laminae_> Awesome, gonna give that a whirl
[02:31:08] <Laminae_> My distro doesn't support that command but i think i know how to do it (maybe)
[02:31:42] <rmu|w> ok then you could delete the wron address with something like "ip a d 10.10.10.10/24 dev enp3s0"
[02:32:52] <rmu|w> but it all depends where you configured that address in the first place, if it was networkmanager it could be it will put it back in a minute or so
[02:34:05] <Laminae_> I edited in "/etc/init.d/networking"
[02:34:18] <Laminae_> One sec, i'll link my broken attempt
[02:35:30] <Laminae_> http://dpaste.com
[02:36:57] <rmu|w> Laminae_: that looks ok, do you know where the 10.10.10.10 in the output of ip addr show did come from?
[02:37:56] <Laminae_> It only showed after i saved that file
[02:38:11] <Laminae_> Prior to that it was all 0
[02:38:54] <Laminae_> To confirm loop, i unplugged the 7i76e and pinged the ip and it is indeed stuck in a loop
[02:39:05] <Laminae_> Which makes me think that file is the cause
[02:39:18] <rmu|w> if you edited network init, you have to restart it somehow
[02:39:26] <rmu|w> what distro is that anyway?
[02:40:41] <Laminae_> A stretch that i pulled from: https://forum.linuxcnc.org
[02:41:08] <rmu|w> then AFAIK the file you want to edit is /etc/network/interfaces
[02:41:08] <Laminae_> Restarted after each change
[02:41:34] <rmu|w> how did you restart?
[02:41:58] <Laminae_> sudo /etc/init.d/networking restart
[02:42:44] <rmu|w> Laminae_: can you show current contents of /etc/network/interfaces ?
[02:43:07] <Laminae_> That was what i last linked

[02:43:36] <rmu|w> ok
[02:43:40] <Laminae_> I'm feeling pretty confident that is where i went awry
[02:43:46] <rmu|w> Laminae_: sudo ifdown enp3s0
[02:43:54] <rmu|w> Laminae_: sudo ifup enp3s0
[02:44:26] <rmu|w> Laminae_: then, in the output of "ip a s", the line showing 10.10.10.10 should be gone
[02:44:46] <Laminae_> "ifdown: interface enp3s0 not configured"
[02:45:12] <Laminae_> sudo ifup enp3s0 RTNETLINK answers: File exists ifup: failed to bring up enp3s0
[02:45:12] <sealive> the pc needs to be 10.10.10.1
[02:45:25] <sealive> the mesa got the 10
[02:45:47] <sealive> you will do a loopback on getting both to the same
[02:45:54] <rmu|w> Laminae_: can you do "ip a d 10.10.10.10/24 dev enp3s0" ?
[02:46:21] <Laminae_> "RTNETLINK answers: Operation not permitted"
[02:46:22] <rmu|w> Laminae_: with sudo of course
[02:46:24] <rmu|w> sorry
[02:46:46] <sealive> sudo ifconfig enp3s0 10.10.10.2

[02:48:06] <rmu|w> like before
[02:48:07] <Laminae_> Got it
[02:49:41] <Laminae_> Current ip addr show: http://dpaste.com
[02:50:39] <rmu|w> ifup did not complain?
[02:50:43] <rmu|w> strange
[02:51:16] <sealive> rmu|w, why dident he install the net-tools
[02:51:25] <sealive> then you got all the benefits

[02:55:36] <rmu|w> if it still shows DOWN you can UP it with sudo ip link set enp3f0 up
[02:56:07] <rmu|w> plugin you network cable
[02:56:30] <Laminae_> Done
[02:56:47] <Laminae_> Success!
[02:56:48] <rmu|w> and can you ping your mesa card
[02:56:52] <Laminae_> I could kiss you right now
[02:57:20] <rmu|w> yw, but i'm fine without ;)
[02:57:50] <Laminae_> Man, i know i had screwed that up, no idea how to fix it x.x
[02:57:57] <Laminae_> I really appreciate your help
[02:58:13] <rmu|w> of course you have to check if /etc/network/interfaces is correct and the config survives a reboot
[02:58:33] <Laminae_> Either way, now i at least know where the problem is
[02:58:39] <Laminae_> But yeah
[02:59:01] <rmu|w> with the ip command, you can abbreviate all commands
[02:59:15] <rmu|w> so "ip a s" is short for "ip addr show"
[02:59:31] <rmu|w> adding "help" usually gives a terse synopsis
[03:00:02] <rmu|w> i have to go, back in about an hour
[03:00:15] <Laminae_> Ah, perfect, i'm very light on linux experience, just debian stuff from pi projects

[04:10:00] <Laminae_> So, i'm plugging in a driver and motor to test and i'm using a gecko g251x which i believe is considered an active high driver, so i only connect step and dir (two wires) to controller, should those be connected to high respectively, since it is an active high driver that seems to make sense to me but ya know...
[04:11:05] <Wolf__> need to hook up the - for the step/dir
[04:12:37] <Wolf__> motor driver won’t work without both sides of the signal
[04:13:18] <Laminae_> I think i explained poorly, this is my driver: https://www.geckodrive.com
[04:16:37] <Wolf__> ok should be in the config to set it to source signals vs sinking
[04:16:45] <Wolf__> or something
[04:17:41] <Laminae_> I'll dig through real quick
[04:17:53] <Laminae_> But it would be connect to the positive side of the signal on controller?
[04:18:13] <Wolf__> yeah
[04:18:44] <Laminae_> Cool beans, sorry for so many dumb questions

[04:31:59] <Laminae_> In axis tabs
[04:32:16] <Laminae_> Doesn't say it would switch it to sourcing, i'm search the googles now
[04:32:26] <Laminae_> I can't be the first person to use these drivers
[04:32:42] <rmu|w> don't understand what you are talking about
[04:33:04] <rmu|w> connect terminal 9-terminal 12 of your gecko to the mesa card
[04:33:10] <rmu|w> 12 to ground
[04:33:49] <Wolf__> those settings arent in axis (I think), if its needed to be set it will be in the mesa directions
[04:34:14] <rmu|w> Wolf__: i think Laminae_ is talking about Axis tab in pncconf or some other configuration program
[04:34:17] <Wolf__> its also 4:30am for me, so I could be wrong
[04:34:29] <rmu|w> Wolf__: not Axis the LinuxCNC GUI
[04:35:18] <Wolf__> yeah, I know where he is talking about, I know I read somewhere about mesa signal settings
[04:36:17] -!- DaPeace has quit [Quit: Leaving.]
[04:36:18] <rmu|w> Laminae_: IIRC the driver selection in stepconf and pncconf selects the timing of step/dir signals

[04:37:05] <rmu|w> Laminae_: some other gecko driver should be fine, that can always be changed later
[04:38:04] <Laminae_> Correct, pncconfig

[04:42:35] -!- WikiPuppies24 has quit [Remote host closed the connection]
[04:43:37] <rmu|w> Laminae_: what do you mean with signal sourcing
[04:44:05] <Laminae_> My drivers only have a step and dir input from controller
[04:44:15] <Laminae_> They are active high drivers
[04:44:42] <rmu|w> ???
[04:45:01] <rmu|w> Laminae_: do you have gecko 251 drivers?
[04:45:01] <Wolf__> double check the mesa manual
[04:45:20] <Laminae_> Those are the exact drivers i have
[04:45:41] <Laminae_> g251x
[04:46:13] <rmu|w> Laminae_: the user manual explains how to wire them up
[04:47:03] <rmu|w> Laminae_: the word "active" isn't even mentioned there
[04:47:09] <rmu|w> Laminae_: connect terminals 9 to 12
[04:47:22] <Laminae_> Yeah, i googled driver types to try and figure it out
[04:47:40] <Laminae_> The manual says "connect pin 10 to step"
[04:47:42] <Laminae_> https://www.geckodrive.com
[04:47:52] <Laminae_> connect pin 9 to direction
[04:47:59] <Laminae_> pretty unhelpful
[04:48:11] <rmu|w> connect 11 to enable
[04:48:14] <rmu|w> connect 12 to ground
[04:48:34] <rmu|w> Laminae_: what information would be considered helpful? what do you need?
[04:49:19] <Laminae_> Am i missing something? pin 11 reads disable
[04:50:06] <Wolf__> hmm
[04:50:07] <Wolf__> The 7I76E provides five channels of step/dir interface with buffered 5V differential signal pairs. Each differential pair consists of two complementary 5V outputs. The differential signals allows reliable signal transmission in noisy environments and can directly interface with RS-422 line receivers. Step motor drives with single ended inputs connect to just one of the STEP and DIR signal outputs, that is either the STEP+/DIR+ or
[04:50:08] <Wolf__> STEP-/DIR- signals, with the unused signals left unconnected at the 7I76E. The input common signal on drives with single ended inputs connects to the 7I76Es GND or 5VP pins depending on the drive type.
[04:51:08] <Laminae_> ooh, perfect, which page was that on?
[04:51:23] <Laminae_> And thanks, exactly what i was looking for
[04:51:26] <Wolf__> I was thinking about something on the field outputs
[04:51:33] <rmu|w> page 11
[04:51:55] <Wolf__> page 15 of the 7i76E manual
[04:52:06] <Wolf__> http://www.mesanet.com
[04:52:41] <rmu|w> mesa documentation does not contain any redundant information ;)

[09:03:32] <LilyFaith> Anyone here? I am a network admin. I know almost nothing about manufacturing, but I work for a manufacturing company. We have a bunch of old excellon CNC 6's attached to Mark V drills. I was originally brought over to figure out if there is a way to upgrade the 5.25 inch drives to USB drives. But my question is why do we need these Excellon CNC 6 controllers from the 70s at all? This software seems like it should do what we
[09:03:40] <LilyFaith> The PC? I know that isn't a simply question but if someone could point me in the right direction to get started I would appreciate it
[09:06:35] <skunkworks> I think your first message got cut off.
[09:07:00] <skunkworks> but yes - linuxcnc is used for exactly that. Converting old machines to current software
[09:07:09] <robotustra> of cause there are some sense in moving to new hardware-software to control cnc
[09:07:29] <robotustra> becase chips are degrade with the time
[09:08:27] <LilyFaith> But how do I figure out where to start with connecting it. In other words (Again I expect this is not a simple question but...) where do I plug the Mark 5 into the PC?
[09:09:19] <robotustra> first you have to find where PC part connects to the stepper controllers
[09:09:51] <skunkworks> heh. you don't. You replace the mark 5.. you have to go though the electronics and see what bits you can keep. (maybe servo drives and such)
[09:09:56] <robotustra> after you have to find out how motors/servos are controlled
[09:10:39] <robotustra> and after that replace PC part with new hardware/software complex
[09:11:09] <LilyFaith> One of you guys want to come to florida and do that?
[09:11:25] <robotustra> ha ha ha
[09:11:49] <robotustra> it looks like real job offer?
[09:12:12] <LilyFaith> I have no idea where to even start. Like I said, I am a IT guy. I don't understand any of this stuff you guys are talking about
[09:12:19] <JT-Shop> Pete lives in florida
[09:12:35] <LilyFaith> It could be a real job offer.
[09:12:48] <LilyFaith> If you could be sure it can be done
[09:13:02] <LilyFaith> and wont affect the reliability of these machines in a negative way
[09:13:07] <skunkworks> I am an IT guy.. Don't all IT guys know electronics?
[09:13:33] <robotustra> unless they are IT girls
[09:13:51] <skunkworks> then they know more...
[09:14:09] <LilyFaith> I know some ;) But I am a software dev/project manager/network admin. Hardware (Even PC Stuff) isn't my thing
[09:17:13] <robotustra> that's sad, such a big country, luck of pros

[09:31:04] <robotustra> it's not enough of information to find out what the system is
[09:32:35] <LilyFaith> I understand that. I just don't know how to figure out the answers to your questions. Do you want me to take pictures of something?

[09:54:01] <LilyFaith> Im being told it is a drill not a router
[09:54:07] <gregcnc> I was just thinking in terms of getting code to it, vs how it's done now
[09:54:43] <gregcnc> somebody needs to look inside the control panels and see what sort of drives it has
[09:55:13] <gregcnc> that will determine how much work is needed to make the upgrade to Linuxcnc, though I think most drives can be used.
[09:58:05] <LilyFaith> https://imgur.com
[10:00:33] <gregcnc> only two axis drives? what controls the drill heads? pneumatics?
[10:00:58] <JT-Shop> looks like servo drives to me, take a photo of the motors that move the axis
[10:03:08] <gregcnc> as old as it is i would expect analog drives and not too much complication
[10:03:46] <gregcnc> there probably isn't any Gcode for Z moves, just a drill command
[10:10:50] <cradek> it's clearly velocity mode servos, not sure what the J6 A-F devices are, or the DO NOT REMOVE board

[10:47:43] <gregcnc> yeah, not a PC in there?
[10:47:43] <cradek> if it really is from the 70s there is probably no CPU and it's a controller made of discrete logic in a box as tall as you

[13:52:26] <jdh> LilyFaith: that is the immediate, cheap, easy solution to your stated problem.
[13:53:10] <jdh> I'd rip it out, put in mesa + linuxcnc.
[13:53:35] <gregcnc> if data transfer is the only issue, (control is not dead) retrofit is a huge undertaking for data trasfer
[13:53:56] <LilyFaith> cool. Whats a MESA and how do I figure out how to wire it in?
[13:54:12] <gregcnc> do you have machine shcematics?
[13:54:35] <jdh> but, tool changers, pnuematics, manual control panel, requires time and expense

[13:56:23] <cradek> soooo much air stuff
[13:56:24] <jthornton> a 7i77 plus a 5i25 or 6i25 or 7i92 will get the machine control
[13:56:39] <cradek> the good part is you can keep all of it as-is. the bad part is you can keep all of it as-is.
[13:56:45] <jdh> heh
[13:57:24] <jdh> cradek: that is me every day at work
[13:58:47] <skunkworks> well - bakc in the day that was cheaper.. Hell we had a machine that shared a servo with 3 axis.. (X,Z and B)

[15:06:41] <LilyFaith> Have any of you heard of "CamSoftCorp" ? Any opinions?
[15:08:03] -!- pj3 has joined #linuxcnc
[15:10:08] <cradek> my opinion is that in your position of needing to do a complicated thing without actually wanting to figure it all out yourself, you're vulnerable to spending a lot of money on a closed system that will be no better in the long term than what you already have
[15:11:00] -!- LilyFaith has quit [Ping timeout: 252 seconds]
[15:11:18] <cradek> using open source software that gives you important freedoms is the only way to avoid those pitfalls
[15:11:27] <andypugh> Pity Pete isn’t here (that guy we keep mentioning) as he is a) In Florida and b) Probably looking for work, in general terms.
[15:11:35] <Tom_L> he timed out
[15:11:36] <cradek> also my opinion is that your net connection is not very good :-)
[15:11:40] <Tom_L> point him to the log
[15:11:42] <Tom_L> :)
[15:12:07] <Tom_L> an IT guy would be on that :D
[15:12:09] <andypugh> (Whereas a lot of us would willingly trade less paid work for more hobby-time)
[15:13:01] <jthornton> aye
[15:13:25] <Tom_L> thing about fixing it for someone, the next thing that would go wrong would be your fault
[15:13:52] -!- pj3 has quit [Ping timeout: 244 seconds]
[15:14:18] <andypugh> One advantage of LinuxCNC (that isn’t often mentioned) is that you can sack your current retrofit and replace with someone else, even if you, yourself, never figure out how it works.
[15:14:30] <XXCoder> some washington rivers is too hot to fish at
[15:14:37] <Tom_L> what does that camsoft use for control software?
[15:14:44] <XXCoder> it gets worse each year
[15:14:48] <andypugh> I meant “sack your retrofit support guy”
[15:14:59] <gregcnc> fire yourself?
[15:15:36] <Tom_L> i've tried
[15:15:39] <Tom_L> never works out
[15:15:51] <gregcnc> keeps showing up eh?
[15:16:21] <gregcnc> hmm who will watch? https://www.youtube.com
[15:16:42] <andypugh> _Somewhere_ there are two little plates that I use to replace the mittors of my bike at trackdays. I made them in about 15 minutes 15 years ago. Now I can’t find them. And if I make some more it will take _way_ more than 15 minutes as I am now much better equipped, and will get elaborate….

[21:45:24] <jdh> I don't know of what you speak, but I don't generally see parts/joins
[21:47:18] <hazzy-lab> freenode (and other IRC networks) has been undergoing a huge spam attack for about the past week
[21:48:16] <jdh> putin troll obvs.
[21:48:48] <hazzy-lab> there seems to have been more join/parts too, maybe the extra load on the network might be cause it??
[21:48:49] <hazzy-lab> lol
[22:01:11] <robotustra> the last thing putin care in his life is IRC
[22:01:55] <robotustra> the topics usually spam pot raise are about admins of irc servers
[22:08:02] <roycroft> actually, the spams claim to be about an irc oper, but the person is actually the subject of some wingnut conspiracy theory
[22:08:13] <roycroft> please don't ask me for details, because i don't remember any
[22:08:32] <roycroft> but when the spams first started coming about, on another network, someone told me that it was a "fake oper"
[22:08:47] <roycroft> and i looked up the name and it was associated with some conspiracy theory
[22:09:00] <roycroft> since i have zero interest in such things i promptly forgot all details :)
[22:22:37] <jdh> I can tell.
