[00:00:47] <Thomaxo_> might be a fun project
[00:01:01] <Thomaxo_> but i'll start with 3-axis first heh
[00:01:08] <malcom2073> Assuming I ever get my mill done, and assuming I make a foundry, and assuming I enjoy casting... etc etc.
[00:01:22] <malcom2073> Yeah, I'll start with a mill, then add a 4th axis and see what happens heh
[00:01:26] <tiwake> why would you get your own foundry?

[00:01:46] <malcom2073> tiwake: For casting small aluminum parts with lost-foam casting
[00:02:06] <malcom2073> CNC the foam, cast, cnc the result, less waste? I dunno.... seemed like a good idea at the time
[00:02:22] <tiwake> sounds like a lot of overhead when not conducting lots of business that uses it
[00:02:40] <malcom2073> I have a 3000lb cnc mill in my garage for "fun".
[00:02:44] <malcom2073> Let's not talk about overhead :)
[00:02:49] <Thomaxo_> https://www.youtube.com/watch?t=66&v=PqzNKKiLMBA
[00:02:58] <Thomaxo_> it does work with cheap software though..
[00:03:11] <Thomaxo_> cheap but awesome software*
[00:03:13] <malcom2073> Thomaxo_: yeah, cheap is a step in the right direction
[00:03:28] <malcom2073> I'm still hoping someday for good open source CAM :P
[00:03:53] <Thomaxo_> i found a python g-code preprocessor recently
[00:04:18] <malcom2073> Yeah, tried using it yet? :)
[00:04:25] <Thomaxo_> nope
[00:04:30] <Thomaxo_> still need to buy the cnc
[00:04:39] <tiwake> oh pycam... heh
[00:04:42] <malcom2073> Give it a shot. I gave up after it hit the 3 hour mark trying to generate gcode for a simple profile

[00:10:26] <malcom2073> Thomaxo_: Is that the machine you got?
[00:10:32] <Thomaxo_> i plan to
[00:10:45] <zeeshan> well youre going along Z
[00:10:47] <zeeshan> so its like drilling
[00:10:50] <Thomaxo_> affordable and pretty big
[00:10:53] <zeeshan> as long as your clearance is correct
[00:10:58] <malcom2073> Buddy of mine has a probotix fireball, similar machine
[00:11:02] <zeeshan> and its just a 3mm uncut chip thickness
[00:11:11] <zeeshan> .118" doc
[00:11:12] <zeeshan> er
[00:11:19] <zeeshan> .118" uncut chip thickness
[00:11:36] <zeeshan> like if you face something with a depth of .118
[00:11:40] <zeeshan> its almost the same situation no?
[00:11:40] <Thomaxo_> yeah does look similar
[00:11:50] <zeeshan> but i guess theres more tool in contact.
[00:11:50] <zeeshan> nm
[00:12:13] <malcom2073> He uses a crappy dremel on his, since he doesn't care much how accurate it is (for some reason), but overall it's a decent design for getting into stuff
[00:13:02] <Valen> zeeshan: like I said you also get a lot of tool rubbing
[00:13:09] <zeeshan> rubbing where?
[00:13:10] <Valen> and you have a long tool hanging out there
[00:13:12] <zeeshan> at the nose?
[00:13:13] <zeeshan> saides?
[00:13:16] <Valen> sides
[00:13:17] <zeeshan> *sides
[00:13:25] <zeeshan> but most inserts look like this:
[00:13:34] <zeeshan> ......... \___/
[00:13:44] <zeeshan> so there is like 3-4 degree side clearance
[00:13:50] <zeeshan> thats a front view

[00:21:27] <zeeshan> i really like this tip:
[00:21:35] <zeeshan> Always reduce feed by 75%, 2 mm (0.08 inch) before centre.
[00:21:55] <_methods> their machining book is like the bible
[00:22:29] <tiwake> malcom2073: uh, I think the driver and motor is something like $3,000-$4,000
[00:22:39] <zeeshan> To avoid breakage, stop feed 0.5 mm (0.02 inch) before reaching the centre and the cut-off part will drop due to its weight and length.
[00:22:40] <zeeshan> lol
[00:22:41] <zeeshan> good point

[00:44:19] <_methods> sure
[00:44:43] <_methods> i usually stick around 65
[00:44:55] <_methods> 75 if i'm feeling froggy
[00:45:05] <_methods> depends on what i'm doing too
[00:45:38] <_methods> but for the looks of that part you should be fine just leave a good cleanup
[00:45:57] <_methods> leave like .05" wall or so
[00:46:16] <_methods> take a nice finish pass on all the contours with a cutter that leaves a nice finish and you should be good to go
[00:47:48] <_methods> i always learned to never use 50% stepover
[00:47:53] <zeeshan> why
[00:47:56] <_methods> not good to hit the tool on centerline
[00:48:04] <_methods> i don't know if it's true or not
[00:48:12] <_methods> but always stay off 50
[00:48:13] <zeeshan> he mentioned something about this in class
[00:48:19] <zeeshan> oh i know why
[00:48:32] <zeeshan> its somethign to do with up and down milling
[00:48:42] <_methods> yeah i guess you're doing both
[00:48:45] <zeeshan> yea
[00:48:51] <_methods> when you're right on centerline
[00:49:05] <_methods> basically the same as taking a full engagement cut
[00:49:16] <_methods> the chips probably go both directions
[00:50:10] <Tom_itx> probably especially true with an odd tooth cutter
[00:50:16] <zeeshan> what is better
[00:50:20] <zeeshan> pocket milling
[00:50:25] <zeeshan> or contouring through a slot

[00:51:00] <zeeshan> http://www.maperformance.com/images/D/LS-Exhaust-Flanges.jpg
[00:51:07] <zeeshan> imagine that flange starting from a rectangular piece
[00:51:20] <zeeshan> im wondering if youll get a longer tool life by contouring the outside of that
[00:51:24] <zeeshan> or cleaning it out in a pocket form
[00:51:28] <zeeshan> in pocket form you'll get a lot more chips
[00:51:48] <zeeshan> and if you decided to just slot through it
[00:51:52] <zeeshan> youd get a lot more head i'd think
[00:51:56] <_methods> i'd just contour it
[00:52:01] <Tom_itx> we would contour it
[00:52:13] <zeeshan> so you would remove all of the outside of it as chips
[00:52:18] <zeeshan> not just one solid chunk
[00:52:19] <Tom_itx> the pieces will break out as you come out of the pockets

[00:54:03] <_methods> you might be able to add something to your fixture to keep that from happening though

[01:04:52] <_methods> don't laser that lol
[01:05:08] <zeeshan> i have lasered something similar in the past
[01:05:14] <zeeshan> and boy is that shit hard to machine
[01:05:27] <zeeshan> i got them to laser cut the holes to tap drill size
[01:05:30] <zeeshan> and i tried to tap it after
[01:05:30] <_methods> yeah that thick on the laser you'll end up with a fair amount of haz
[01:05:35] <zeeshan> that was REALLY hard hahah
[01:05:54] <_methods> yes tapping 304 after applying heat is bad
[01:06:03] <zeeshan> so after that experience , i got them to cut a much smaller starting hole
[01:06:08] <zeeshan> just for location
[01:06:24] <zeeshan> and then i drilled it with m42 and then tap
[01:06:42] <zeeshan> more work , but no broken tap teeth
[01:07:07] <_methods> yeah that's when some anchorlube comes in handy
[01:07:55] <zeeshan> i wish i had my coolant setup working
[01:07:57] <zeeshan> there is no tank
[01:08:03] <zeeshan> and no collection tank
[01:08:07] <zeeshan> so itll piss all over the floor
[01:08:18] <zeeshan> i really dont wanna kill the 1/2 carbide end mill
[01:08:19] <zeeshan> it was expensive
[01:08:38] <zeeshan> if i can cut 6 flanges out of it, then it can die
[01:08:49] <Tom_itx> i'm not sure about running carbide dry in SS but we ran it dry alot in Al
[01:09:28] <Tom_itx> i suppose you're better off with coolant
[01:09:36] <_methods> if you can run without coolant completely than it's worth doing
[01:09:53] <_methods> but it's when you get coolant in there when you're running dry that will screw you
[01:10:06] <zeeshan> thermal fatigue?
[01:10:11] <_methods> i've found that if i'm running dry i have to run ALL dry
[01:10:12] <zeeshan> boom goes the edge?
[01:10:17] <_methods> no coolant on any cycles
[01:10:31] <_methods> so basically any part with drilling i rule out for running dry
[01:10:49] <_methods> but if i have a part that's all milling i'll try and run all dry
[01:11:23] <_methods> anyways good luck i'm goin to bed
[01:11:30] <zeeshan> cu! thanks for the help

[11:54:44] <malcom2073> SpeedEvil: Yeah, apparently they touched down near vertical, but it was still moving slightly sideways and tipped over. Much better than the hit-and-explode of last time heh
[11:55:05] <SpeedEvil> Sure

[12:19:14] <malcom2073> The actual full sized hit and miss and old style farm engines went from anywhere from $100 to $1000 depending on condition, most of which look like they'd been sitting in a barn for 40 years.

[13:55:03] <SpeedEvil> What do you mean low pressure
[13:55:19] <malcom2073> 10-15psi, and lots of flow (for running steam engines on air for demonstration purposes)
[13:55:22] <SpeedEvil> A roots style supercharger _is_ a compressor that will generally output that
[13:57:27] <malcom2073> hmm, this guy needs 25-30psi, dunno if the roots could do that. I have a M90 laying around I should fiddle with sometime
[13:57:36] <malcom2073> Stick a box on the output with a pressure gauge and spin it up heh

[13:59:02] <SpeedEvil> I'm wondering of steam fr a different reason - though at 240C/normal pressure for drying wood
[13:59:09] <SpeedEvil> well - processing
[13:59:40] <SpeedEvil> flash boilers are neat
[13:59:41] <malcom2073> He wants to drive a compressor of some type with a 1/4hp steam postion, to run 6 smaller steam engines on air heh
[13:59:54] <malcom2073> I want to eventually get int osteam, but boilers scare the crap out of me
[14:00:18] <SpeedEvil> yeah - the key to non-scary is to have ~0 water at high pressure
[14:00:48] <malcom2073> Even steam at high pressure can permanently disfigure
[14:00:59] <malcom2073> water can slice ya, but steam cna do pretty nasty things too
[14:01:08] <SpeedEvil> And any steam available constrained by pipework
[14:01:16] <SpeedEvil> And distance
[14:01:48] <SpeedEvil> The concern over water isn't really that.
[14:02:19] <SpeedEvil> The concern is that a tank of water at (say) 180C has a _LOT_ of energy stored and waiting to go bang in a millisecond
[14:02:31] <malcom2073> Ah yeah, leak == pressure loss == flash boiling
[14:02:44] <SpeedEvil> If the tank rips
[14:02:57] <SpeedEvil> _BAD_ stuff happens
[14:02:59] <malcom2073> Yeah

[18:40:21] <zeeshan> rab
[18:40:30] <zeeshan> is the bb better than the rp2?
[18:40:59] <malcom2073> better for what?
[18:41:05] <zeeshan> performance wise
[18:41:22] <malcom2073> I believe the rp2 has more processing power
[18:41:26] <malcom2073> But no realtime element
[18:41:30] <zeeshan> hm
[18:42:03] <Rab> zeeshan, I believe rp2 is also better as a media player.
[18:42:21] <zeeshan> they have "FreeRTOS"
[18:42:21] <PCW> bbb is about on par with a 500 mhz pentium3
[18:42:22] <malcom2073> yeah the bb isn't capable of 1080p
[18:42:23] <zeeshan> for rp2
[18:42:25] <Rab> BBB has a lot of very flexible I/O.
[18:42:47] <malcom2073> zeeshan: Yeah but that's bare metal :P
[18:42:49] <Rab> malcom2073, in fact it is, but only at 24fps with HDMI audio disabled.
[18:43:17] <malcom2073> Rab: Nice heh, thought it couldn't handle it at all. I've never actually tried higher resolutions on mine
[18:43:26] <Rab> malcom2073, for a desktop. I don't think video playback would work very well.
[18:43:42] <malcom2073> Heh
[18:44:43] <malcom2073> I don't use my bb for anything video related anyway so I dunno
[18:44:54] <Rab> Requires a recent-ish Debian image and I had to add some kind of boot option.
[18:44:56] <zeeshan> maybe i shoulda bought the bb for daq reasons
[18:44:57] <zeeshan> :/
[18:45:19] <malcom2073> depends what're you daqing?
[18:45:40] <zeeshan> like strain gages through adc
[18:45:41] <Rab> Shrug, either platform should be able to talk to a serial ADC/DAC.
[18:45:47] <zeeshan> but the spi serial rate
[18:45:51] <zeeshan> prolly depends on the os latency?
[18:46:23] <zeeshan> am i correct on this assumption?
[18:46:25] <zeeshan> cause i have no clue
[18:46:46] <malcom2073> zeeshan: The maximum rate? Probably, but your ADC is probably slower than the max either the rpi or bb can do heh
[18:47:30] <zeeshan> how do i find out? :)
[18:47:36] <Rab> Also you won't be measuring your strain gages at hundreds of MHz.
[18:47:47] <malcom2073> zeeshan: datasheets!
[18:47:51] <zeeshan> i know
[18:47:52] <zeeshan> but what spec

[18:49:26] <malcom2073> Implementation details vary by application :P
[18:49:29] <lair82__> I am still getting greenmill@greenmill:~/sserial/utils/linuxcnc$ ./updatess 7i71 7i80 1 set jumper on remote device to setup mode cycle remote device power and then hit return ./updatess: line 20: halrun: command not found set jumper on remote device back to operate mode and cycle remote device power
[18:49:36] <Rab> Yeah, that sample rate is trivial.
[18:50:07] <zeeshan> so i guess the real time os stuff becomes more critical
[18:50:12] <zeeshan> when trying to measure high frequency signals
[18:50:15] <lair82__> This 7i71 was bought back in october, should already be current.
[18:50:24] <malcom2073> Neither the rpi or the bb are DSP's
[18:53:20] <Rab> zeeshan, unless you need to process and respond to the signal in real time, as with a servo driver, raw speed will serve you better than low latency. So a desktop computer would work better than a slow BBB with a bunch of RT optimization.
[18:54:02] <zeeshan> that reminds me of something else
[18:54:10] <zeeshan> i dunno if you saw the video yesterday of me parting off some steel
[18:54:26] <zeeshan> i noticed there are "step changes" in speed when in CSS mode
[18:54:35] <zeeshan> and i think this is due to the delay in modbus
[18:54:39] <zeeshan> :/
[18:54:53] <zeeshan> its not as big of a deal in milling

[18:56:39] <cradek> yep
[18:56:51] <zeeshan> its like 1/2 s delay
[18:56:56] <zeeshan> from what i my ears are telling me
[18:57:00] <cradek> depends how fast you're going then
[18:57:20] <zeeshan> usually for tapping i wouldnt go faster than 100 rpm
[18:57:34] <cradek> motion will follow it, even if there's some delay in reversal
[18:58:56] <zeeshan> for my vfd, i know there is about 2 s delay between fwd and rev at that rpm
[18:58:58] <zeeshan> due to no brake
[18:59:08] <zeeshan> brake resistor -- could i somehow compensate?

[18:59:23] <zeeshan> the delay mostly coming from decel and acel
[18:59:35] <cradek> just tap slowly I guess
[18:59:53] <cradek> but yeah adding a resistor often gives you faster reversals
[19:00:13] <cradek> or some other settings, like braking regen to power line
[19:00:30] <zeeshan> i have that setup
[19:00:37] <zeeshan> it works great at low rpm
[19:00:43] <zeeshan> but i think i dont have it setup right
[19:00:55] <zeeshan> because at high rpms , the internal braking causes over voltage
[19:00:59] <zeeshan> and puts the drive in limp mode
[19:01:16] <cradek> my GS2 has a setting something like "regen-brake as fast as possible without faulting"
[19:01:17] <zeeshan> there must be an option to set it up so it brakes faster at low rpm
[19:04:29] <zeeshan> okay i found it
[19:04:40] <zeeshan> "DC braking frequency setting"
[19:04:49] <zeeshan> The frequency at which DC braking activates during decel.
[19:05:05] <zeeshan> so if i set that to a low hz value it shouldnt trip

[19:21:05] <lair82__> PCW I got it to work, I copied the linuxcnc folder out of /sserial/utils/ into the linuxcnc-dev folder, moved to that directory, then ran the ./updatess-eth 7I71 7I80 1 and success!!
[19:21:35] <PCW> yeah the script depends on linuxcnc being available
[19:21:54] <lair82__> PCW was it right to modify the ssinstall file though, and specify the .bin file for the mv command?
[19:24:21] <PCW> ssinstall looks right to me (mv *.BIN)

[19:25:18] <PCW> there was a bug in an earlier version but it should be fixed in the current zip file
[19:28:34] <lair82__> PCW ok, hopefully it's quiet on my end for a while, I am to the point now of bringing up the drives and moving things around. Thanks again for help :)

[20:26:10] <zeeshan> man this is why i want a big lathe
[20:26:11] <zeeshan> :(
[20:27:39] <XXCoder> off center is scary
[20:27:52] <zeeshan> my lathe would prolly walk across the garage
[20:27:54] <zeeshan> if i did that
[20:28:03] <XXCoder> add lead weights
[20:28:19] <XXCoder> and add rubber that doesnt bounce under it
[20:28:22] <zeeshan> i dont think i would be spinning a 175 lb piece in my lathe
[20:28:23] <zeeshan> :-)
[20:28:29] <zeeshan> thats like 10% its weight!
[20:28:34] <XXCoder> lol

[22:19:45] <Cromaglious_> hmm sharp inside corners.. I haven't figured how to do that with an engraving bit in software yet
[22:20:12] <zeeshan> i was thinking of just tracing the outside of that pattern
[22:20:15] <zeeshan> with an engraving bit
[22:20:19] <zeeshan> but my machine only goes to 3150 rpm.
[22:20:23] <zeeshan> so im not sure how to do it
[22:29:56] <Cromaglious_> can you strap a dremel to your Z?
[22:30:16] <zeeshan> i could, but it'd be extra work :/
[22:30:45] <Cromaglious_> think of the future

[22:33:16] <zeeshan> i could make a mount
[22:33:20] <zeeshan> that uses the front 3 threaded holes
[22:34:25] <zeeshan> http://imgur.com/a/A1y9f
[22:34:28] <zeeshan> or completely take off the head
[22:34:44] <zeeshan> and use the 4 mounting holes
[22:34:56] <zeeshan> so i can take advantage of full travel
[22:35:15] <Cromaglious_> for a dremel, the 3 holes would work... get a piece of 1/2" AL
[22:35:15] <zeeshan> hmm
[22:35:29] <zeeshan> what kind of engraving bit did you use?
[22:35:49] <Cromaglious_> I have 60 degree 1/8"
[22:36:06] <zeeshan> http://www.amanatool.com/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/4/5/45766.jpg
[22:36:08] <zeeshan> like that?
[22:36:09] <Cromaglious_> and crap 1 cutting surface 30 degree
[22:36:30] <_methods> http://www.eltool.com/Products/SpindleSpeeders/Howtheywork.aspx
[22:36:39] <Cromaglious_> that's like my 30 degree bits
[22:36:39] <zeeshan> methods i cant afford that
[22:36:39] <zeeshan> :)
[22:36:43] <zeeshan> those are like 3k
[22:36:48] <_methods> go sell some shit
[22:36:52] <zeeshan> no
[22:36:55] <zeeshan> not for engraving
[22:37:02] <_methods> get a job
[22:37:11] <zeeshan> even if i had 3k laying around
[22:37:13] <zeeshan> i wouldnt buy that
[22:37:20] <zeeshan> :-)
[22:37:28] <_methods> haha
[22:37:51] <zeeshan> cant i just engrave at 3150 rpm
[22:37:52] <zeeshan> :/
[22:37:55] <zeeshan> its only aluminum
[22:37:58] <_methods> sure
[22:38:09] <_methods> why can't you?
[22:38:13] <zeeshan> i feel like itll snap
[22:38:14] <Cromaglious_> these

[22:38:34] <Cromaglious_> go slow, really slow
[22:38:37] <_methods> just use a center drill
[22:38:47] <zeeshan> wow
[22:38:49] <zeeshan> thats not a bad idea.
[22:38:55] <zeeshan> :-)
[22:38:58] <zeeshan> i like
[22:39:03] <Cromaglious_> nd go really slow
[22:39:10] <zeeshan> whats really slow though
[22:39:24] <zeeshan> 0.001 ipr?
[22:39:27] <zeeshan> chip load?
[22:39:30] <Cromaglious_> center drills really dislike radial loads
[22:40:00] <Cromaglious_> hmm 3K... probably .4ipm
[22:40:05] <_methods> meh i just run it whatever
[22:40:08] <zeeshan> thats not enough chip load
[22:40:14] <zeeshan> itll just plough
[22:40:29] <Cromaglious_> play with it then
[22:40:33] <_methods> you're thinking too much
[22:40:37] <zeeshan> no man
[22:40:39] <_methods> again
[22:40:41] <zeeshan> lol
[22:40:55] <Cromaglious_> chuck one up, and go until you break it, then back off 30%
[22:41:02] <zeeshan> haha
[22:41:21] <Cromaglious_> it's a center drill flip it over and go to it
[22:41:29] <zeeshan> http://www.ebay.com/itm/10pcs-3-175mm-Carbide-PCB-Engraving-Bits-CNC-Router-Conical-Flat-Tool-30-0-2mm-/111222325095?pt=LH_DefaultDomain_0&hash=item19e55dff67
[22:41:30] <zeeshan> these are local
[22:41:53] <zeeshan> but ill try with a center drill first
[22:42:03] <zeeshan> or grind one out of hss
[22:42:30] <Cromaglious_> that's basically my 30 degree bit
[22:42:38] <Cromaglious_> the .2mm end is really big
[22:44:25] <_methods> test it on a scrap of alum
[22:44:28] <_methods> you have the mill there
[22:44:40] <_methods> then you'll know if you want to use the centerdrill
[22:44:57] <_methods> i use it for engraving that i really am not worried about
[22:45:03] <zeeshan> why?
[22:45:04] <_methods> or if the specs are just whatever
[22:45:05] <zeeshan> flexes too much?
[22:45:16] <_methods> it's big dia
[22:45:25] <_methods> so works best with big letters
[22:45:31] <_methods> it's not the best engraver
[22:45:32] <zeeshan> these are pretty big
[22:45:33] <zeeshan> like..
[22:45:35] <_methods> but if you're in a bind
[22:45:36] <_methods> they work
[22:45:38] <zeeshan> the height of the H
[22:45:44] <zeeshan> is like 3/4" tall
[22:45:49] <_methods> liek i said try it on a scrap
[22:45:49] <zeeshan> by .5" wide
[22:45:51] <_methods> see how it looks
[22:45:58] amnesic is now known as amnesic_away
[22:46:38] <zeeshan> sounds good :)
[22:48:23] <zeeshan> i found some m42 round
[22:48:25] <zeeshan> 1/4"
[22:48:33] <zeeshan> i think i can grind it to an engraving bit
[22:48:48] <zeeshan> (if center drill idea doesnt work)
