[01:49:22] <miss0r> are you up to anything interresting, pink?
[01:49:46] <pink_vampire> need to make 3 pvc parts
[01:51:19] <miss0r> doesn't sound too crazy ;)
[01:51:58] <pink_vampire> I'm thinking to make one of them with the sine plate
[01:54:07] <miss0r> sweet. do you have some drawings I can look at?

[02:21:20] <pink_vampire> miss0r: https://i.imgur.com
[02:21:50] <miss0r> that is a pretty interresting looking part. Might I ask what it is for?
[02:22:03] <pink_vampire> sure
[02:22:34] -!- holzjunkie has quit [Ping timeout: 250 seconds]
[02:22:45] <pink_vampire> it is actually 3 parts that going to be glue together,
[02:23:50] <miss0r> are you going to be glueing the flats with the holes together?
[02:25:03] <pink_vampire> https://i.imgur.com
[02:25:38] <miss0r> ahh, so the part is made up of three seprate parts
[02:25:44] <miss0r> Why not make it as one?
[02:26:31] <pink_vampire> i have the pvc in sheets, and it is very easy to glue
[02:26:52] <pink_vampire> this is just a fancy holder to the servo driver
[02:27:05] <miss0r> true. if acuracy is not of the essence :)
[02:27:34] <miss0r> My job for today is not nearly as intertaining.
[02:28:15] <miss0r> At the moment I am waiting for some relays to get here via mail. Then I have to replace the innerts of some emergency stop redundand relay controller...
[02:28:20] <miss0r> alot of soldering today

[05:31:03] <jthornton> you gotta love programmers documentation lol
[05:31:04] <jthornton> Set/Get the position of the camera in world coordinates.
[05:31:04] <jthornton> The default position is (0,0,1).
[05:31:35] <jthornton> wtf does (0,0,1) mean lol
[05:31:43] <jthornton> https://vtk.org
[05:32:52] <XXCoder> x0 y0 z1
[05:33:33] <XXCoder> i dunno why its not 0 0 0 tho lol
[05:33:34] <jthornton> you would think they would spell that out lol
[05:34:53] <Loetmichel> XXCoder: probab,y because you would have the ground plane splitting your picture in half then ?
[05:35:29] <XXCoder> hmm guess thats true
[05:35:35] <XXCoder> depends on setup
[05:36:09] <jthornton> vtk has almost zero information about it
[05:37:40] <XXCoder> setviewUP? up? weird
[05:38:15] <jthornton> yea I think that rotates the object to set the up side
[05:40:08] <XXCoder> many of those functions is pretty olvious just odd in some cases
[05:40:49] <jthornton> wow I have 0.3GB of data per day for the rest of the month lol
[05:41:04] <XXCoder> thats fun
[05:42:39] <jthornton> I installed a module in my new store and it broke the store... going to take two days to delete the online files and upload again lol
[05:42:58] <XXCoder> bleh
[05:43:10] <XXCoder> my phone I only use .5 gb a month approx
[05:48:22] <miss0r> so, should any of you ever find yourself in a picle & realy realy needing to replace the relay board of a siemens 3TK2608 redundand safety relay, let me know :)
[05:48:58] <miss0r> I have just spend the morning reverse engineering it, designing the PCB and am currently isolation milling the first one
[05:49:27] <XXCoder> nice though dont need one lol
[05:50:47] <miss0r> yeah.. hehe
[05:51:06] <miss0r> They have gone out of production. and they are SO expensive, I can do this and the client still comes out on top
[05:51:41] <Loetmichel> siemens. what did you expect?
[05:51:50] <miss0r> Loetmichel: Exactly that
[05:51:51] <miss0r> :)
[05:52:27] <Loetmichel> like a supplier once said: "BRauchste was gescheits oder darfs auch von siemens sein?"
[05:52:48] <Loetmichel> (do you need something proper or will siemens parts do?"
[05:52:51] <Loetmichel> )
[05:53:57] <miss0r> lol
[05:57:23] <miss0r> I might not have thought this one through...
[05:57:41] <miss0r> I can't seem to find support for ellipse throughhole milling in coppercam
[05:58:43] <jthornton> opps
[05:59:45] <Tom_L> morning
[06:03:05] <miss0r> ffs! I just broke the tip of the routing tool
[06:05:28] <jthornton> morning
[06:05:49] <miss0r> mornin indeed
[06:06:38] <Loetmichel> miss0r: thats why you order the V-bits in 10-packs ;)
[06:06:46] <miss0r> I hope that thing was just worn... and that theres nothing wrong with the tool path :] I will go get some lunch & when I come back I hope to find a finished part and not another broken tip
[06:07:10] <miss0r> Loetmichel: Sure.. but this is a much nicer tool i'm using.
[06:07:25] <miss0r> 60degree v-bit with spital flutes
[06:07:38] <miss0r> leaves a realy pretty finish. but it is rather expensive :D
[06:07:42] <miss0r> anywho bbiab
[06:08:29] <Tom_L> 18°F Hi 26
[06:09:12] <Loetmichel> miss0r: i use those with 30°: https://www.sorotec.de
[06:09:31] <Loetmichel> not cheap but well worth the price
[06:12:45] <Tom_L> revisited my thread macro last night and added user selectable multi passes
[06:12:55] <Tom_L> http://tom-itx.no-ip.biz:81
[06:13:09] <Tom_L> noticed on some coarse threads 2 might not be enough
[06:15:36] <Tom_L> Loetmichel better than a halfround bit?
[06:17:08] <Loetmichel> Tom_L: you mean a "D-bit"?
[06:17:24] <Tom_L> yeah same thing :)
[06:17:29] -!- syyl_ has joined #linuxcnc
[06:17:31] <Loetmichel> WAY better. especially in metal
[06:17:51] <Loetmichel> it has the right cutting angle for alu and brass
[06:18:14] <Loetmichel> unlike the D-bits which have the inner angle at 0°
[06:18:21] <Tom_L> right
[06:19:46] <Tom_L> hah china's idea of it: https://www.ebay.com
[06:20:12] -!- syyl has quit [Ping timeout: 252 seconds]
[06:21:43] <Loetmichel> MUHAHAHA
[06:22:24] <XXCoder> wtf
[06:22:59] <XXCoder> is it drill? is it endmill? is it engraver sharp bit? how about ALL!
[06:23:04] <Tom_L> reground broken drillbits :D
[06:24:28] <Loetmichel> looks like it, yes
[06:24:33] <XXCoder> yeah
[06:24:41] <XXCoder> kinda good idea, because why not.
[06:24:50] <XXCoder> but price bit high for just regrund tool
[06:33:56] -!- holzjunkie has quit [Ping timeout: 255 seconds]
[06:40:36] <miss0r> Loetmichel: I use something that looks like it. only my carbide has a Ti coating on the end
[06:50:33] <Loetmichel> XXCoder: i do that all the time with broken TC mill bits... freehand. i wouldnt sell them though: https://www.youtube.com
[06:50:47] <miss0r> ffs. This project is not going my way
[06:50:57] <miss0r> It seems I am out of 0.8mm carbide endmills
[06:51:07] <miss0r> I have 50+ 0.5 and 50+ 1.0
[06:51:16] <miss0r> and alot of the even smaller ones that I never use
[06:51:21] <miss0r> damnit :D
[06:51:26] <XXCoder> is it radius sensive?
[06:51:34] <XXCoder> ie: makes features that depend on radus
[06:51:49] <miss0r> yeah
[06:51:58] <XXCoder> too bad. oh well
[06:52:04] <miss0r> It seems that is the only way I can do the ellipse slots in the coppercam software
[06:53:47] <miss0r> I suppose I can cheat it to use a 0.5... but using a 0.8 would allow me to do it ALOT faster :)
[06:53:54] <miss0r> also, they are not as prone to breaking
[06:54:00] <XXCoder> yeah
[06:54:52] <Loetmichel> indeed. the smalles 2 flute i use regularily is 0.6mm
[06:55:18] <Loetmichel> the 0.4mm i have you cant even sneeze near the machine when they are cutting without them breaking ;)
[06:55:29] <miss0r> I found one!
[06:55:55] <miss0r> but its a stubby bastard... I think I will get a slightly tapered hole pushing it through a 1.5mm PCB
[06:56:40] <miss0r> Apparently I have a few, actualy - I just had to look in the chinesium drawer
[07:07:16] <pink_vampire> i just use an end mill for pcb
[07:07:55] -!- emsjessec has joined #linuxcnc
[07:08:53] <Loetmichel> pink_vampire: works if you have pretty coarse PCBS.
[07:09:17] <Loetmichel> http://www.cyrom.org <- 0.8mm end mill
[07:09:32] <pink_vampire> 1/32" (0.8mm)
[07:09:56] <pink_vampire> yeah similar to the stuff i do
[07:10:18] <Loetmichel> http://www.cyrom.org <- 0.1mm 30° V-bit
[07:10:48] <pink_vampire> can't see anything
[07:11:04] <Loetmichel> https://www.youtube.com <- video
[07:11:17] <Loetmichel> with a 30° v-bit
[07:11:27] <Loetmichel> and 1mm FFC connectors adapter
[07:11:40] <pink_vampire> pshhhhhhhhhhhhhhh
[07:11:55] <XXCoder> I wonder how fine a engraver can be done lol
[07:12:04] <Loetmichel> XXCoder: depends on machine
[07:12:17] <XXCoder> yeah though there must be a lower bound?
[07:12:28] <Loetmichel> i am hard pressed to do 0.1mm wide insulation channels. 0.2mm works fine
[07:12:41] <Loetmichel> 0.3mm and you can use F2000 ;)
[07:13:00] <Loetmichel> (mm/min)
[07:13:17] <XXCoder> interesting
[07:13:35] <Loetmichel> https://www.youtube.com 0.2mm wide insulation channel, F1200 ;)
[07:13:45] <miss0r> oh gawd!
[07:13:52] <miss0r> ffs :-/
[07:14:09] <miss0r> Instructions: linear motion with a 0.8mm endmill to make a 0.8mm slot
[07:14:30] <miss0r> actual outcome: 1.6mm wide slot because it thinks it needs to clean up the hole or something
[07:14:45] <Loetmichel> result: http://www.cyrom.org
[07:14:46] <miss0r> now the whole soldering island is gone
[07:15:01] <XXCoder> Loetmichel: nice video!
[07:16:13] -!- syyl_ has quit [Quit: Leaving]
[07:24:25] <miss0r> Why the hell has it decided that my slots are so wide!?!
[07:25:05] <pink_vampire> miss0r: where?
[07:25:19] <pink_vampire> miss0r: where?
[07:25:31] <miss0r> doing a pcb at the moment. and I just wrecked it...
[07:25:50] <miss0r> I have some relays I need to solder on there, which has spade connectors. I needs slots for those
[07:26:04] <pink_vampire> what do you mean?
[07:26:22] <miss0r> and the cam software has decided to completely ignore the size I have set and made up its own
[07:26:31] <miss0r> and it seems theres nothing I can do to change its mind

[07:27:31] <pink_vampire> ?
[07:28:04] <pink_vampire> my irc got disconnected
[07:32:01] <XXCoder> miss0r: weird allright. sometimes wish theres better previews
[07:32:20] <XXCoder> like vr milling lol realistic looking so you can actually see how it looks like.
[07:32:31] <XXCoder> with imports of object you plan to mill
[07:32:49] <miss0r> well... it 'does' show the slotted through hole as an oversize.. but I didn't notice it
[07:32:58] <miss0r> and I am apparently unabled to change it at the moment :S
[07:40:44] <miss0r> Some of the more expensive cam/cad packages has that
[07:40:49] <miss0r> This is not expensive...
[07:40:56] -!- P1ersson has joined #linuxcnc
[07:41:06] <miss0r> I don't recall how much it was (Oh my god yes, I have actualy payed for something) :)
[07:41:06] -!- P1ersson_ has joined #linuxcnc
[07:41:12] <XXCoder> lol
[07:41:46] <miss0r> but I pretty much had to get it. It was the only software that could talk directly to my desktop mill
[07:42:27] <miss0r> 80eur for a lisence .)
[07:43:00] <XXCoder> not too bad
[07:49:18] <miss0r> but it is still fucking with me :-(
[07:56:31] <pink_vampire> https://www.youtube.com
[07:56:50] <pink_vampire> now i want to get a lock
[08:04:06] <XXCoder> you can get special power switch that has lock built in it
[08:04:59] <x2s> Hi. People from Germany, where do you get your milling cutters from? Any suggestions for a shop?
[08:04:59] <pink_vampire> i have a main switch with option for 3 locks
[08:05:00] <XXCoder> i heard of one guy who was inside larger cnc mill when operator come in and started machine :(
[08:05:07] <XXCoder> got very dead. :(
[08:07:08] <TekniQue> you can also get special tag plates for LOTO operation
[08:07:14] <TekniQue> that you can attach a bunch of locks to
[08:07:28] <TekniQue> if you have more than one person in the danger zone
[08:08:27] <TekniQue> https://www.totallockout.com
[08:08:29] <TekniQue> this kind of stuff
[08:14:19] <miss0r> x2s: what are you milling?
[08:15:06] <miss0r> well, in either case; have a look at kemmler
[08:24:01] <x2s> miss0r: wood and aluminium
[08:24:53] <miss0r> well. kemmler has some good stuff. also, the prices are very reasonable. I live in Denmark, but have a local supplier that sells the kemmler brand. Would be worth looking up - I believe it is german
[08:26:01] <miss0r> might be a smidge expensive, if you are running a hobby shop. But the right stuff costs a little extra
[08:26:09] <x2s> miss0r: will have a look. Thank you
[08:26:16] <miss0r> no problem
[08:26:56] <x2s> 12-15 EUR is ok
[08:27:26] <x2s> if it's worth the price and doesn't stays sharp for a long time, it's a good investment
[08:28:04] <miss0r> revisit that last line :)
[08:28:17] <miss0r> but, I know what you are getting at :)
[08:29:51] <x2s> Eh, yes :D
[08:31:09] <x2s> Kemmler doesn't have cutters with 3mm shaft diameter :/
[08:33:02] <miss0r> perhaps if you can find a seller of sgs tools
[08:33:38] <miss0r> sutton tools are also within acceptable
[08:34:10] <pink_vampire> x2s: i just get stuff from ebay
[08:34:19] <pink_vampire> about 3$ for end mill

[09:48:44] <pink_vampire> no
[09:48:58] <pink_vampire> just the high seed spindle
[09:49:26] <gregcnc> no solution for the supply voltage?
[09:49:52] <pink_vampire> servo driver
[09:51:03] <gregcnc> yeah it died, we figured it was due to regen on braking and suggested dumping excess voltage
[09:51:34] <pink_vampire> I made the return energy dump
[09:51:54] <pink_vampire> I'm trying to rebuild it now
[09:51:59] <gregcnc> ah ok
[09:52:33] <gregcnc> someone was asking about DIY tool setter. i couldn't find links you yours
[09:52:40] <pink_vampire> also the spindle going to get the old DC controller from the original spindle of the machine

[12:56:51] <fragalot> in my mailbox: "grand opening of new pool!"
[12:57:17] <gloops> so you missed it lol
[12:58:04] <fragalot> :D
[12:58:10] <fragalot> it looked fun
[13:02:03] <MarcelineVQ> local pond found to be mostly kerosene, claims charred man
[13:02:30] <fragalot> lol
[13:02:55] <fragalot> https://www.vrt.be
[13:04:09] <MarcelineVQ> really though a pool burning down, that's fairly comical

[14:56:13] <miss0r> so.. I need better software :D
[14:56:20] -!- micges__ has joined #linuxcnc

[14:56:52] <fragalot> unless you need the part RIGHT NOW, it makes zero sense to DIY circuit boards anymore these days
[14:57:02] <miss0r> well I do with this one
[14:57:02] -!- micges__ has quit [Read error: Connection reset by peer]
[14:57:11] <miss0r> but the remaining 5 I will order there
[14:57:29] <fragalot> etch it then :P
[14:58:08] <miss0r> nah.. I'm milling the second side of the pcb now. I managed to line it up. but it took waaay too much effort with a calculator and manual offsetting
[14:58:24] <fragalot> what are you milling it on?
[14:58:34] <fragalot> please don't say the maho with the super slow spindle :P
[14:58:39] <miss0r> the roland camm-3
[14:58:49] <miss0r> hey.. respect the maho! :D
[14:58:55] <fragalot> :D
[14:59:02] <fragalot> they still haven't run the deckel at work >.>
[14:59:11] <miss0r> meh..
[14:59:29] <miss0r> are you not allowed near it?
[14:59:44] <fragalot> not part of my job description to mill out the cabinets
[14:59:56] <miss0r> so, thats a yes?
[15:00:03] <fragalot> all I did was set the machine up for them ready to use, and went back to my normal tasks
[15:00:24] <miss0r> throw a wrench in the gearbox, and have them call me to repair it :D
[15:00:27] <fragalot> i'm allowed near it if I want to, just have more pressing matters to attend to :p
[15:00:31] <fragalot> haha
[15:01:27] <miss0r> I think I'll press my luck and try'n engrave my logo on this pcb... what could possibly go wrong? :D
[15:01:45] <fragalot> go all out and only mill it half the copper depth :P
[15:03:42] <miss0r> hehe.. I think this setup combining MDF, double sided tape & oddball PCB blanks will make that a real challange :D
[15:04:08] <miss0r> unless somehow the gods smile upon me, and they all equal out... :o
[15:04:14] <fragalot> xD
[15:04:22] <fragalot> depends on the moisture content of the MDF
[15:04:41] -!- CNC_Brian has joined #linuxcnc
[15:04:47] <miss0r> that depends on where you measure... near/far away from the most resent coffee spill...
[15:05:03] <miss0r> I wonder how/if it is possible to convert a jpeg to vectors in diptrace...
[15:05:17] <miss0r> nah... I have other software to do that
[15:05:21] <miss0r> screw coppercam
[15:05:32] <Jymmm> miss0r: I don't know what diptrace is, but you can in inkscape
[15:05:47] <fragalot> inkscape ftw for that stuff
[15:06:09] <miss0r> Jymmm: thanks :) But I have some realy low tech software that can run the cnc direct that can do that as well
[15:06:25] <miss0r> also, the software I have for that is called dr. engrave and is only 102kb :D
[15:06:36] <miss0r> so; the bare minimum
[15:07:27] <gloops> PVA the mdf
[15:08:15] <fragalot> pva everything.
[15:08:26] <fragalot> make sure to add the moisture first
[15:08:46] <fragalot> for best results, replace way lube with pva
[15:09:19] <miss0r> well.. that escalated quickly..
[15:10:41] <miss0r> fragalot: Theres alot of ways to do this; but the only relays I could get on a short notice that met the requirements have those nasty flat spade connectors on'em.
[15:10:54] <miss0r> so I basically needed atleast the through holes to be milled
[15:11:14] <fragalot> bigger hole & bigger glob'o'solder :D
[15:11:26] <gloops> tape doesnt stick to mdf well, a lot better when its sealed
[15:11:52] <miss0r> hehe, I also thought about that to be honnest - but I ran into a design issue... I didn't have enough room to route everything with circular pads
[15:12:01] <fragalot> depends on the tape, the stuff I use tears the mdf in half if you try to peel it off
[15:12:10] <miss0r> gloops: If my double sided tape sticks any better to the MDF, I could never get it off
[15:12:35] <miss0r> does that also line up beautifuly on your screen? :D
[15:12:51] <fragalot> the end of it does
[15:12:55] <gloops> which tape is this?
[15:13:36] <miss0r> for low force applications(like PCB) I use some nitto tape
[15:13:47] <fragalot> I use the cheap stuff from 'action', a discount shop here.. no idea what brand it is, but that stuff is impossible to release from anything even remotely unpolished
[15:13:56] <gloops> (i was thinking masking tape + superglue)
[15:14:10] <fragalot> but it comes off easily using chemicals
[15:14:32] <miss0r> for high strength, I use the double sided tape that the carpenters use when assembling the moisture resistant plastic sheets around the insulation
[15:14:55] <miss0r> that stuff does not come off in a hurry
[15:15:11] <miss0r> i've never found masking tape & superglue to my liking, honnestly
[15:15:20] <miss0r> I usualy superglue directly :)
[15:16:40] <gloops> hmm, you can get really sticky double sided stuff like that from upvc window supplies, in varying thickness, from 1mm up
[15:17:04] <fragalot> you want it to be thin & stiff
[15:17:07] <fragalot> not thick & spongey
[15:17:20] <gloops> 1mm is ok
[15:19:09] * miss0r is seriously pondering weather or not to add the logo.
[15:19:39] <miss0r> With the days events leading up to this; theres a 50/50 chance I'll cut 3 leads & two pads in half trying
[15:20:28] -!- andypugh has joined #linuxcnc
[15:20:28] <miss0r> so; I think I'll go ahead and give it a go :D
[15:21:22] <fragalot> mill yourself a blacksmith's stamp & stamp your logo
[15:21:29] <fragalot> :D
[15:21:31] <miss0r> haha
[15:21:34] <miss0r> yeah :D
[15:21:38] <fragalot> just whack it on there
[15:21:52] <miss0r> I think my chances of success is about the same either way
[15:22:16] <fragalot> if it's a low speed circuit, i'm a bit disappointed you didn't have the traces as your logo
[15:22:32] <miss0r> next time you can do the design for me.
[15:22:37] <fragalot> no.
[15:22:48] <miss0r> b..but.. I insist?
[15:23:33] <fragalot> ..maybe.

[17:59:16] <Jymmm> Well, new hose seems to be holding 100 PSI so far =)
[17:59:28] * Jymmm pokes CaptHindsight for no reason
[18:02:07] <Tom_L> what's it rated for?
[18:03:15] <Jymmm> The hose is rated for 300PSI, but the gauge I have on the far end max out at 100 psi
[18:03:58] <Tom_L> is it bending the needle yet?
[18:04:05] <Jymmm> I charged the hose to 100, then turned off the nitrogen tank.
[18:04:10] <Tom_L> if not it's stil 100psi
[18:04:18] <Jymmm> and just waiting right now
[18:04:28] <Tom_L> leak test
[18:04:33] <Tom_L> what's the hose for?
[18:04:51] <Jymmm> pretty much. propane is what I'm going to use it for
[18:05:33] <Tom_L> yeah you were looking at fittings a while back..
[18:05:42] <Jymmm> I found the fittings
[18:06:01] <Tom_L> dunno what that has to do with surgical tweezers...
[18:06:04] <Jymmm> https://www.homedepot.com
[18:06:21] <Jymmm> and the hose is field repairable too =)
[18:07:47] <Tom_L> i've got a flex hose on my compressor that has no clamps, just a push on fitting
[18:08:03] <Tom_L> i was a little skeptical when i got it but it's never failed or leaked
[18:08:12] <Tom_L> ~175psi
[18:08:30] <Tom_L> just rubber hose pushed on the fitting
[18:10:41] <Tom_L> that stuff cracks after while
[18:11:03] <Tom_L> at least the outer
[18:12:31] <CaptHindsight> ooooouuuuucchhhh
[18:12:40] <CaptHindsight> sorry over reacted
[18:21:14] <jthornton> push on hose with the correct fitting will not come apart without a knife

[18:45:16] <CaptHindsight> nice time?
[18:45:21] <tiwake> I was vibrating the entire time... lol... I love machines so much
[18:45:45] <tiwake> last night I slept for 10-11 hours
[18:46:09] <tiwake> (was at the show yesterday)
[18:46:33] <tiwake> they had some 3D printers, but no SLS type
[18:46:41] <CaptHindsight> big shows can be fun
[18:48:43] <tiwake> they had one there where it was a plastic+metal thing and the plastic gets baked out
[18:49:38] <tiwake> I didn't like it though
[18:49:55] <tiwake> gotta buy special crap
[18:55:15] <CaptHindsight> they make most of their money on the special crap
[18:55:28] <tiwake> yeah
[18:55:49] <tiwake> I don't want special crap, I just want SLS... heh
[18:56:00] <CaptHindsight> the closed designs all use the inkjet model
[18:56:26] <CaptHindsight> lock in
[18:56:40] <tiwake> CaptHindsight: for SLS, does there have to be support structures? or is the surrounding powder good enough support?
[18:56:55] <CaptHindsight> there seems to be price fixing for plastic SLS powders
[18:57:05] <CaptHindsight> the surrounding power is the support
[18:57:23] <tiwake> alright, figured it would be fine
[18:57:52] <tiwake> what about warping for larger parts? does it happen very much?
[18:59:00] <tiwake> cause I want to build an SLS that would be able to make an engine head... heh
[19:00:24] <Tom_L> it can
[19:01:02] <tiwake> Tom_L: can if I don't make the settings correct or something?
[19:01:24] <Tom_L> http://tom-itx.no-ip.biz:81
[19:01:28] <tiwake> suppose it would also depend on the material
[19:01:28] <Tom_L> see the lego at the top?
[19:01:32] <Tom_L> that's TI
[19:01:57] <CaptHindsight> tiwake: the powders are typically held in an oven during printing
[19:02:09] <CaptHindsight> this help keep the materials from warping
[19:02:20] <tiwake> hmm
[19:02:29] <CaptHindsight> less power to melt/sinter is required
[19:02:45] <CaptHindsight> you don't typically hit the powders with a laser at room temp
[19:03:01] <tiwake> unless its something like sugar, yeah
[19:03:07] <CaptHindsight> often it is just below the melt temp by a few degrees
[19:03:37] <tiwake> hmm
[19:03:40] <CaptHindsight> sugar printers are more for fun than exact part tolerances
[19:03:53] <tiwake> well sure... heh
[19:04:04] <tiwake> for elaborate cake toppings
[19:04:48] <CaptHindsight> https://imgur.com the build chamber has the lid removed in this pic, it's on the left
[19:05:49] <tiwake> how powerful of a laser do you think I want? and probably a CO2 laser?

[19:06:23] <tiwake> aluminum?
[19:06:38] <CaptHindsight> sure
[19:07:01] <CaptHindsight> 1050nm diode lasers require dark powders
[19:07:19] <tiwake> I'd imagine a few hundred watts

[19:08:37] <CaptHindsight> depends on how fast you want to sinter
[19:09:09] <CaptHindsight> it's a matter of how many joules hits the material, so think watts over time
[19:09:33] <CaptHindsight> 200w in 1 second vs 20w in 20 seconds
[19:10:00] <CaptHindsight> er 10 seconds would be equal
[19:10:17] <CaptHindsight> also laser spot size

[19:24:34] <Jymmm> CaptHindsight: Nah, tapping into the 250gal propane tank quick connect
[19:25:04] <Jymmm> for the generator and/or emergency propane heater instead of using the 5 gal tanks.
[19:25:09] <Tom_L> i got lantern adapters that conenct to the tank
[19:25:47] <Jymmm> Tom_L: I'm tapping into the 250gal tank, not bbq tanks
[19:26:03] <Tom_L> i don't have a 250 gal tank
[19:27:10] <Jymmm> Well, that's what II'm working on because it's a 50ft run
[19:27:50] <Jymmm> But, it'll be after the regulator, so what, 1/2 PSI I believe
[19:27:55] <Tom_L> https://www.pinterest.com
[19:28:02] <Tom_L> does it look like any of those?
[19:28:51] <Jymmm> https://66.media.tumblr.com
[19:29:39] <Jymmm> Tom_L: ^^^^^^
[19:30:17] <Tom_L> no style
[19:31:21] <Jymmm> I'm just hoping that 1/4 PU hose holds up
[19:31:59] <Jymmm> and is actually able to deliver the needed volume
[19:32:02] <Tom_L> why not use hard copper?
[19:32:30] <Jymmm> for propane???
[19:32:46] <Tom_L> well i mean the tube instead of a hose
[19:32:56] <Jymmm> Right now, this is a temporary/emergency way to tap into the big tank.
[19:34:40] <Jymmm> If there was an extended outage, I might run out of propane using 5Gal tanks. I dont have to worry about that now.

[19:35:11] <Tom_L> i had one of those hooked up to a small heater for a while
[19:35:56] <Jymmm> Yeah, I have a hose too, but not to tap into the 3/4" black pipe, thus that setup I posted a pick of
[19:36:45] <tiwake> hmm
[19:36:46] <Jymmm> in a safe manner, and now able to connect to anythign that needs it using those ACME fittings
[19:37:49] <Jymmm> and I cna evacuate the hose before disconnecting
[19:37:54] <tiwake> if I had a line boring machine or jig of some sort for boring out the cam journals in ford overhead cam engines, I could get a fair amount of work
[19:38:14] <tiwake> anyone know about stuff like that?

[19:46:23] <tiwake> Tom_L: was it a sunnen?
[19:46:33] <tiwake> or a custom thing?
[19:47:51] <Tom_L> custom iirc
[19:48:03] <Tom_L> did all the journals at once
[19:48:19] <tiwake> how was the machine set up?
[19:48:45] <Tom_L> you inserted it in the case and used a good size drill iirc
[19:48:52] <Tom_L> it's been a day or so since i've seen it
[19:48:56] <tiwake> heh
[19:50:42] <tiwake> now that I'm thinking about how things need to line up and stuff, I should be able to make something
[19:50:58] <Tom_L> https://www.youtube.com
[19:52:25] <Tom_L> it was very similar if not that one
[19:53:58] <tiwake> interesting
[19:54:16] <Tom_L> we did dozens of em back in the day..
[19:54:57] <Tom_L> quite literally in and out in a day
[19:56:45] <Tom_L> did that and added stud inserts so the cylinder studs wouldn't pull out again
[20:06:14] <Tom_L> i'm not sure how that feed mechanism worked

[20:15:30] <Tom_L> tiwake can you get oversize bearings for the camshaft bores?
[20:25:34] <tiwake> Tom_L: on the ford cam bearings, it just rides on the bare aluminum
[20:26:41] <tiwake> so need to cut oversize, weld it up, and cut back to size
[20:26:50] <tiwake> or something like that
[20:26:56] <Tom_L> what about warpage?
[20:27:03] <Tom_L> and oil passages

[23:41:23] <Tom_L> did you have to swap encoders?
[23:42:02] <Tom_L> get that all tuned and you can send it to me for my spindle :)
[23:42:08] <skunkworks> I am in the process of swapping encoders.. the cui ones seem to suck/
[23:42:51] <skunkworks> for feedback anyways. we have one on the K&T spindle - for motor rpm. Seems to work fine in that situation.
[23:43:00] <Tom_L> that was 750w right?
[23:43:02] <Tom_L> iirc
[23:43:03] <skunkworks> yes
[23:43:43] <Tom_L> what's the black box?
[23:44:39] <skunkworks> middle picture?
[23:44:47] <Tom_L> yeah
[23:45:12] <skunkworks> it is a supply from an amc servo drive that was bad.. Has filtering and clamping.
[23:45:33] <skunkworks> (it is the dc supply for the power stage of the servo drive)
[23:45:51] <Tom_L> what voltage?
[23:46:09] <skunkworks> it is rectifying 120v - so it outputs about 160
[23:46:11] <skunkworks> ish
[23:46:13] <Tom_L> yeah
[23:46:16] <skunkworks> http://electronicsam.com
[23:46:19] <Tom_L> that's what i wondered
[23:46:21] <skunkworks> cui encoder.
[23:46:27] <Tom_L> if it was direct off 120vac
[23:46:44] <Tom_L> nice
[23:46:46] <Tom_L> :)
[23:46:58] <skunkworks> normal optical encoder...
[23:46:59] <skunkworks> http://electronicsam.com
[23:47:30] <Tom_L> didn't know they were sawtooth output
[23:47:40] <Tom_L> figured they'd be more square
[23:48:23] <skunkworks> - no - that is the jog of the servo drive - it is saw tooth because it is 1 per rev...
[23:48:34] <skunkworks> The noise is what I was showing
[23:55:56] <skunkworks> same tuning between the 2
