[00:02:12] <archivist> how many anyway
[00:02:25] <Computer_Barf> well I was hoping to make 48 at a time
[00:02:56] <Computer_Barf> making them one at a time is really unappealing

[00:12:04] <Computer_Barf> maybe i cut half the depth , then flip

[00:14:23] <Computer_Barf> my preference is not being broke
[00:14:31] <malcom2073> Really though, you can do a lot better design, that is MUCH easier to machine. That part was designed by printer people

[00:15:39] <archivist> parts should be designed around your machining facilities
[00:16:03] <_methods> and mental facilities

[00:16:25] <Computer_Barf> archivist: im feeling like I want to have a slitting saw on my mill
[00:16:37] <malcom2073> That one is easy to machine out of a block, and only requries two clamping positions to do
[00:16:43] <archivist> I use slitting saws in the vertical
[00:17:21] <malcom2073> The key thing is, it's machinable. The printrbot one was never *meant* to be machined, it was designed to be printable, unknown *why*, since it would never work as a printed part
[00:17:26] <archivist> I get a blank page with google drive, it is useless
[00:18:31] <malcom2073> Point is though, design it with machining in mind. Design it with multi-part plate machining in mind even if you're looking to mass produce

[00:21:29] <Computer_Barf> ok but what exactly is wrong about having two screws holding the part down and milling that side?
[00:21:45] <archivist> nothing
[00:21:49] <Computer_Barf> just that it has to do so much deep slotting and it might jam?
[00:22:01] <malcom2073> Nothing really, but you can't clamp the part where it's slotting
[00:22:04] <malcom2073> otherwise it will jam
[00:22:28] <Computer_Barf> i just thought that the screw would be holding it down
[00:22:34] <archivist> deep slotting is the and chips clogging/snapping the cutter

[07:04:06] <Computer_Barf> lol
[07:04:14] <zeeshan> the carbide ate it
[07:04:17] <Computer_Barf> cause stainless is my arch nemesis
[07:04:18] <zeeshan> the bits that got owned were hss
[07:04:38] <zeeshan> stainless i dont mind
[07:04:42] <zeeshan> just feed hard and its ok
[07:04:51] <zeeshan> this thing has gotten me baffled
[07:04:57] <zeeshan> i finished the job, but im worried for the future!
[07:05:12] <Computer_Barf> have you ever drilled a 3/4 inch hole in quarter inch ss plate?
[07:05:37] <Computer_Barf> i was able to do smaller holes no problem but getting that big i couldn't get it to work without work hardening
[07:06:23] <Computer_Barf> i would try to keep it cool , resharpen the tool , pecking, etc
[07:06:49] <Computer_Barf> but that was pre mill , just a small drill press so it could just be hp
[07:07:16] <Computer_Barf> ill find out when I get back to that project later this month
[07:08:53] <Computer_Barf> i would have thought bronze would always be softer than hss
[07:09:16] <Computer_Barf> i mean isn't that just copper and zinc or some other copper alloy

[07:21:47] <archivist> some of his stuff I would avoid
[07:22:11] <Computer_Barf> I have the same gears that he used cause they came with the mill and are just pulled out
[07:23:54] <Computer_Barf> I know its not the best option, but it's at least an option
[07:24:30] <Computer_Barf> the guy earlier's suggestion of a horizontal mill isn't exactly on my list of options

[07:25:20] <Computer_Barf> I've also been considering building a power hacksaw
[07:25:47] <Computer_Barf> slitting through an inch of aluminum though..

[08:13:50] <Computer_Barf> i don't mean flood coolent though, i mean oil
[08:14:07] <Computer_Barf> like thicker oils rather than thin fluids
[08:14:28] <archivist> use the right oil for the job
[08:14:35] <Computer_Barf> ive never seen a thicker oil used in an enclosure
[08:14:51] <archivist> gears use thick oil
[08:15:05] <Computer_Barf> just wondering why thicker oils arn't appropriate in many of these applications
[08:15:14] <archivist> eg EP90 in a back axle
[08:16:01] <Computer_Barf> I wonder if hosses case was welded at the seams and filled with oil it would quite down
[08:16:03] <archivist> depends on the contact pressure and mode and speeds
[08:16:24] <archivist> hoss case is spastic
[08:17:09] <Computer_Barf> well , i can understand given that he needed to machine it on his mll
[08:17:29] <archivist> has he even got proper seals
[08:17:49] <Computer_Barf> I assume not
[08:18:00] <Computer_Barf> im just meaning, if you made it to be sealed
[08:18:06] <archivist> as it is open when removed, that is another reason
[08:18:45] <archivist> proper right angle attachments have 4 bearings and separate shafts and seals
[08:19:25] <archivist> the input gear would be permanent inside the case

[08:36:14] <Computer_Barf> i just checked my angle grinder, it has three seperate spots where you can screw the handle into the cast casing , looks like its quarter inch taps
[08:36:32] <Computer_Barf> im sure I can mill up some sort of bracket for mounting it on the side of the mill
[08:37:19] <archivist> add an extra clamp to the body

[13:14:27] <jthornton> I suspect part of my problem with ttt is some font files are open type font files
[13:14:45] <_methods> yeah fonts are a nightmare
[13:15:11] <jthornton> I have one that works YEA and two that give me an error

[13:18:23] <jthornton> I wonder if the freetype lib is choking on opentype fonts
[13:18:44] <_methods> no idea but open loops always cause porblems

[13:19:17] <jthornton> that's the error I get
[13:20:35] <_methods> wonder if the table has permission issues
[13:22:31] <jthornton> they all have the same permissions
[13:22:52] <_methods> and it works on other computers just not this one?
[13:23:09] <_methods> it's gotta be a problem with the fonts
[13:23:40] <jthornton> lol, I can't even get it to work with the same font on another computer
[13:23:48] <_methods> hmmm
[13:24:14] <_methods> gotta love linux lol
[13:24:49] <archivist> looks a bit like the include library by that line number OTF_drive_tables:686: OTF-Error (Invalid table)
[13:25:10] <jthornton> I just downloaded some with .otf extensions so I assume they are opentype fonts for sure I think
[13:25:20] <archivist> which ttt version anyway
[13:26:08] <jthornton> I assume it is 4. something that comes with the debian live cd
[13:28:40] <jthornton> however I see no version information
[13:29:16] <jthornton> I get the same OTF error with a .otf font...
[13:31:47] <archivist> -v gives version info
[13:33:16] <jthornton> V4.0-2 and it also prints out the G code for Hello*world* lol
[13:33:36] <archivist> that is the default text :)

[15:20:38] <JT-Shop> nope nurbs sucks for plasma even 2.7
[15:20:48] <JT-Shop> does ttt 3 use only lines and arcs?

[15:34:05] <JT-Shop> oh I better pack up the shipments for Monday first
[15:34:34] <cradek> JT-Shop: what sucks about the nurbs?
[15:35:04] <JT-Shop> it runs at about 1/2 to 1/3 the speed of lines and arcs
[15:35:19] <JT-Shop> F60 and I get 25-35 on a nurb
[15:35:26] <JT-Shop> IPM
[15:35:56] <JT-Shop> as soon as it hits a line its going 60IPM
[15:36:25] <cradek> I'm surprised because they decompose right away into arcs
[15:36:30] <JT-Shop> these are 3" tall letters so it should not have a problem making 60IPM
[15:37:23] <cradek> it still does it in 2.7? might be an actual bug then
[15:37:28] <cradek> argh I have to run
[15:37:42] <cradek> if you think it's a bug please file a bug with a how-to-reproduce

[16:27:18] <t12> plc programmign is much more annoying than anticipated
[16:33:20] <_methods> it's very logical lol
[16:33:58] <JT-Shop> it's really simple to program a plc if you know the simple rule
[16:34:25] <t12> teleport yourself into 1940

[16:34:49] <_methods> something software "engineers" can't seem to bring themselves to do
[16:35:04] <JT-Shop> t12, what kind of PLC are you programming?
[16:35:17] <t12> mitsubish melsec-q
[16:35:57] <JT-Shop> been a long time since I programmed a mitsu melsec
[16:35:59] <t12> more just trying to wonder around the system and make sense of it
[16:36:07] <t12> have some servo drives that take no step/dir
[16:36:18] <t12> but theres a positioning module that does do step/dir to them
[16:36:31] <JT-Shop> does it still use a dos based programmer?
[16:36:33] <t12> for whatever reason it cannot/will not comm with the servo drive tho
[16:36:36] <t12> nah its windows
[16:36:41] <t12> gx configurator/gx developer
[16:36:58] <_methods> yeah that gx developer program is kinda wonky
[16:37:00] <JT-Shop> ah, told you it's been a while since I touched one of those
[16:37:09] <t12> unclear if i need to have the plc do some handshaking with the pos controller
[16:37:13] <t12> before it will wake up and see the servos
[16:37:22] <_methods> i just had to reladder out hydmech saw
[16:37:26] <t12> or if i should be able to directly mess with the servos via configurator
[16:37:38] <t12> with a null plc program
[16:38:20] <_methods> i've never tried to manually activate servos through gxconfigurator/developer
[16:38:25] <t12> ultimate goal is really to reverse engineer sscnet i think
[16:38:36] <t12> but need stimulus/response data to do so
[16:39:53] <t12> i have a feeling i'm missing something silly though
[16:41:58] <t12> maybe the sscnet if on the positoning module is blown or something
[16:50:18] <furrywolf> wtf? I got a check for $86 from state fund. a dividend on my premium payment, or something like that.
[16:52:05] <furrywolf> normally every time I open anything from them, it's another unexpected and utterly incomprehensible bill that has to be paid within ten days or they cancel my policy. now they send me a check, with an equally incomprehensible form.
[16:55:02] * furrywolf is very tempted to spend it on a BS Atelier Lines Paris, but probably should be responsible and not spend unexpected money on toys, no matter how tempting it is

[17:29:32] <zeeshan> man
[17:29:38] <zeeshan> i cant figure out this bronze nonsense
[17:29:38] <zeeshan> lol
[17:31:44] <zeeshan> so assuming it's just as bad as stainless for work hardening
[17:32:06] <zeeshan> my process of drilling was center drill, then 1/4" drill, then 5/16" drill
[17:32:18] <zeeshan> these happened fairly okay without much drama (still required a lot of feed)
[17:32:22] <zeeshan> more than steel
[17:33:00] <zeeshan> but when iwent to the 7/16" drill, it just did not wanna go through. the only thing i can think is -- my uncut chip thickness was 1/16" -- and this would be how thick the work hardened layer was
[17:33:24] <adb> sry, youtube is down for you too ?
[17:35:10] <_methods> hahah bronze is a bastard
[17:35:17] <zeeshan> edude
[17:35:17] <_methods> kerosene is your friend
[17:35:20] <zeeshan> i had to sharpen drill
[17:35:25] <zeeshan> like 8x
[17:35:31] <zeeshan> and broke 3 7/16 drill bits
[17:35:32] <zeeshan> lol
[17:35:49] <zeeshan> i tried 5/16" carbide vs 5/16" hss
[17:35:51] <_methods> what are you using for coolant
[17:35:55] <zeeshan> and the carbide didnt require must feed
[17:36:02] <zeeshan> i was using cutting oil - sulphur based
[17:36:12] <zeeshan> *must = much
[17:36:33] <_methods> well i use kerosene when i'm just tryin to git'r'dun with bronze
[17:37:01] <_methods> but otherwise you need to get your drill geometry right and correct tooling
[17:37:22] <zeeshan> what is it supposed to be
[17:37:27] <zeeshan> for drill geometry
[17:37:29] <_methods> i use stainless steel geometry
[17:37:34] <zeeshan> isnt that 118 deg
[17:37:36] <_methods> what 120deg point?
[17:37:46] <zeeshan> yea my grind is 120 deg
[17:38:06] <zeeshan> the bronze was so unexpected
[17:38:10] <zeeshan> he was supposed to give me copper
[17:38:14] <zeeshan> and it ended up being bronze.
[17:38:20] <_methods> crusty old machinist taught me to put like an extra relief on the tip
[17:38:27] <_methods> like a radius back cut
[17:38:36] <zeeshan> my drill grinder has 3 settings
[17:38:41] <zeeshan> 6, 12, 18 degree clearance
[17:38:43] <zeeshan> its set to 12
[17:38:44] <_methods> i used to get him to grind the drills for me lol
[17:39:30] <_methods> that face mill you have with those diamond shaped inserts works best for getting agood finish in bronze too

[17:40:49] <_methods> i hate brass/bronze/copper
[17:40:51] <zeeshan> but doesnt know if its as bad as stainless
[17:40:55] <zeeshan> brass dude
[17:41:03] <zeeshan> i did the same thing but smaller scale in brass
[17:41:10] <zeeshan> it took 45 min to do both parts
[17:41:18] <zeeshan> where as the same parts in this whaterver bronze material
[17:41:24] <zeeshan> took me 5 hours to do!
[17:41:31] <zeeshan> the drilling part
[17:41:31] <_methods> hahah
[17:41:45] <zeeshan> i had to finish the job for today , couldnt go buy caride drill in the right size
[17:42:09] <zeeshan> brass is softer than aluminum
[17:42:09] <zeeshan> to drill
[17:42:14] <zeeshan> but the chips are annoying
[17:42:26] <zeeshan> they come out like powder almost
[17:42:31] <zeeshan> cause i guess of the lead content?
[17:42:41] <archivist> brass needs the drill modifying to stop grabbing
[17:43:02] <zeeshan> i didnt notice any issues..

[20:49:15] <robinsz> I spent the day messign with the Wayfarer, writing some code

[20:49:46] <andypugh> Wayfarer?
[20:49:52] <robinsz> dinghy
[20:50:23] <andypugh> Ah, right. I spent the day riding back from Hay-on-Wye and getting rather cold in the process.
[20:50:43] <robinsz> it was a little chilly
[20:50:52] <robinsz> if you come past worcester ...
[20:50:59] <robinsz> you are always welcome for tea
[20:51:07] <robinsz> well, past Bewdley anyway
[20:51:33] <andypugh> I think I would have to be fairly lost to pass Worcested in the way from Hay on Wye to Essex :)
[20:51:59] <robinsz> well, yes
[20:52:14] <robinsz> you came back down the M50?
[20:52:40] <andypugh> Hmm, actually Google maps suggests going via Worcester and the M40…
[20:52:45] <robinsz> yes
[20:53:05] <robinsz> hay to New Radnor
[20:53:10] <robinsz> then A40 to Worcester
[20:53:16] <robinsz> north, turn right
[20:53:24] <andypugh> But I actually go via Ledbury, Witney, Bicester and Aylesbury to minimise M25
[20:54:03] <robinsz> well, whatever, you are always welcome should you pass this way

[21:27:29] <Tom_itx> did you figure out how to run both your cnc's at once or is that still an issue for the converter?

http://bodgesoc.blogspot.co.uk/search/label/Tools
[22:08:38] <malcom2073> SpeedEvil: Is that enough power?
[22:09:21] <SpeedEvil> andypugh: yes - that's my second 'to be constructed' kiln.
[22:09:46] <SpeedEvil> The above mentioned one is a prototype for a rather larger glass fusing kiln eventually.
[22:10:29] <SpeedEvil> The round one is intended to be gas-tight and argon filled
[22:10:45] <SpeedEvil> well - not gas tight - but argon filled, which implies...
[22:13:11] <andypugh> I made a furnace using 4 x halogen bulbs once as an experiment when I was a metallurgiist.
[22:13:32] <andypugh> It sort-of worked except that keeping the electrical terminals cool enough was difficult.
[22:13:44] <SpeedEvil> yeah - there are special 'hot' terminal ones
[22:14:04] <SpeedEvil> But I'm assuming I'll need little sleeves over the end to the outside, and insulators over the top of them
[22:14:21] <SpeedEvil> (as I'm too cheap to buy the proper ones)
[22:15:19] <JT-Shop> now I need a way to punch a hole or 3 in some velcro strips
[22:15:34] <andypugh> JT-Shop: Build a laser head for the plasma
[22:15:34] <SpeedEvil> Heated thing
[22:15:36] <SpeedEvil> melty
[22:15:48] <pcw_home> arch punch
[22:15:59] <SpeedEvil> yeah, or that.
[22:16:10] <SpeedEvil> If you're bored, you could try the drill press
[22:16:13] <SpeedEvil> :)
[22:16:18] <andypugh> SpeedEvil: I think I would forget the halogen elements actually, and just get some nichrome wire.
[22:16:46] <SpeedEvil> andypugh: I probably agree - though someone did make a brick kiln with them
[22:17:07] <SpeedEvil> andypugh: if they can be made to work well enough, they could make a very nice compact 'turn key' kit.
[22:17:21] <JT-Shop> arch punch?
[22:17:25] <SpeedEvil> JT-Shop: paper
[22:17:34] <JT-Shop> oh
[22:17:36] <SpeedEvil> JT-Shop: For punching holes in paper to fit in a lever arch file
[22:17:54] <andypugh> You get a lot of nichrome wire for the price of a halogen bulb
[22:18:07] <JT-Shop> I have some nichrome wire
[22:18:18] <SpeedEvil> andypugh: One whole pound.
[22:18:24] <SpeedEvil> (the halogen bulbs)
[22:18:43] <SpeedEvil> I'd really like some SiC elements
[22:18:50] <SpeedEvil> But those are more annoying to source
[22:19:12] <JT-Shop> hmm I found a 13/64" punch for $8 on mcmaster
[22:19:14] <andypugh> One problem with halogen bulbs is that the way they work is the halogen gas gettering the evaoporated metal off of the cold quartz and re-depositing on the hot element. If the glass is in a hot environment then that effect is rather reduced.
[22:19:52] <SpeedEvil> andypugh: yes - however mitigated by lowering the operating power - and the fact that I pretty much don't care once they hit ~20-30 hour life.
[22:20:03] <SpeedEvil> As by that time the electricity cost dominates.
[22:21:48] * JT-Shop needs to go spatchcock the chicken
[22:22:12] <SpeedEvil> (and yes, I know that they may not even hit that) They are a self-supporting 'turn key' heating element that's cheap, heats up really fast, and is at least potentially immune to high temperatures. They've got lots of potential downsides - but the upsides make them interesting at least
[22:23:07] <SpeedEvil> And they're in the right form factor I could possibly just swap in a SiC element if I get bored with screwing around.
[22:24:01] <_methods> best way to cook a chicken fo sho
[22:25:23] <andypugh> SpeedEvil: Yes, all those reasons are why I decided to try it.
[22:26:19] <SpeedEvil> I'm planning on keeping the ends to ~150C or so.
[22:27:08] <andypugh> Well, let us know how it goes.

[22:46:02] <_methods> pain in the ass?
[22:46:19] <JT-Shop> not bad really, I tried a zillion before I settled on opencart
[22:46:36] <JT-Shop> it ain't perfect for me but close enough to work

[22:47:36] <malcom2073> I wasted a week on that before I found opencart :/
[22:47:39] <_methods> i think i tried zencart
[22:47:48] <JT-Shop> I tried them all lol
[22:47:49] <_methods> and it was horribly painful
[22:48:10] <JT-Shop> yea zencrap sucked
[22:48:13] <malcom2073> _methods: Probably was zencart :)
[22:48:15] <_methods> the whole money thing scares the hell out of me
[22:48:20] <malcom2073> Horribly painful is exactly how I'd describe it
