[10:58:15] <Loetmichel> you see?
[10:58:29] <chd> yes, tnx :-)
[11:00:41] <chd> interesting photos in your gallery :-)
[11:02:30] <Loetmichel> which in special?
[11:03:08] <chd> I'm interested in the cases - do you mill them or via laser/plasma?
[11:03:32] <Loetmichel> mill
[11:03:58] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14877&g2_imageViewsIndex=1
[11:04:23] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14160&g2_imageViewsIndex=1 <- there you can see all states
[11:04:52] <Loetmichel> just milling them with slots at the bends and then bending by hand/small vice
[11:05:56] <Loetmichel> most work is to think ricvht for material that vanishes in the bends
[11:06:04] <Loetmichel> so the screw holes iwll fit ;-)
[11:06:09] <Loetmichel> right
[11:06:25] <chd> good work :-) I'am trying to cut my cases with a fine plasma cutter (stainless steel 0,8 and 1mm)
[11:06:35] <chd> Yes, bending is a real science :-)
[11:06:55] <Loetmichel> most case prototypes i do 3 to 4 times;-)
[11:07:02] <Loetmichel> until i worked out all kinks
[11:07:15] <chd> ;-)
[11:08:27] <chd> For this reason I am modifying my bending machine for automatic backstops - to get fitting sheets
[11:09:39] <Loetmichel> as i bend by had: no bending machine ;-)
[11:09:45] <Loetmichel> i have to tink beforehand
[11:09:50] <Loetmichel> think
[11:09:56] <Loetmichel> hand
[11:10:43] <Loetmichel> its 1.5mm Aluminium, AlMg3, milled down to 0,8mm at the bends
[11:10:50] <chd> Really good work. I will glue my cases - that's much easier and you get flat surfaces.
[11:10:54] <Loetmichel> you can bend it by hand if large enough
[11:11:02] <chd> Yes
[11:11:10] <Loetmichel> for smaller stripes you'll need a vice to get it straight
[11:11:38] <Loetmichel> i cant glue. the cases should be RF tight
[11:11:44] <Loetmichel> ABSOLITELY
[11:11:47] <Loetmichel> up to 4ghz
[11:12:16] <chd> ah ok :-)
[11:12:50] <chd> and using copper foil in side is not an option?
[11:13:11] <Loetmichel> would be. but we are producing for the military mostly
[11:13:18] <chd> uhhh ;-)
[11:13:20] <Loetmichel> soldiers and delicate parts dont mix well
[11:13:35] <Loetmichel> do it "idiot proof" and still some soldier will break things off ;-)
[11:14:49] <chd> What software do you use for CAM? I'm still searching for a good one
[11:15:07] <Loetmichel> dont laugh: corelDraw 8 and BoCNC
[11:15:44] <Loetmichel> i just bought cambam, but have to get used to it
[11:16:50] <chd> @corel: if it works - why not?
[11:17:07] <Loetmichel> more or less
[11:17:15] <Loetmichel> its so old that it doesnt run inder win7
[11:17:23] <Loetmichel> i had to set up a VM with xp ;-)
[11:17:51] <Loetmichel> and of course its 2d only
[11:22:00] <chd> for plasma cutting this is ok - I'm also testing Cambam (it runs native under Linux) - looks fine - but I haven't done a real case with it. First the plasma cutter has to run :-)

[12:52:51] <zbychuk> Hi, I have d2700mud motherboard with integrated graphics in cpu
[12:53:18] <zbychuk> i disabled all power saving functions in BIOS
[12:53:37] <zbychuk> disabled Hyperthreding
[12:53:54] <zbychuk> added isolcpus=1 to kernel cmdline
[12:54:59] <zbychuk> and when i run 1 instance of glxgears and iceweasel, and then start moving windows on the screen
[12:55:39] <zbychuk> then jitter latecy 25us jumps to about 18000ns
[12:55:49] <SpeedEvil> In principle, integrated graphics will contend with various resources often.
[12:55:57] <SpeedEvil> At least, for example, for RAM bandwidth.
[12:56:20] <SpeedEvil> Non shared memory cards won't in general be nearly as bad.
[12:56:32] <SpeedEvil> also - 25us to 18000ns is an improvement

[12:59:55] <zbychuk> but it was without any boot parameters or anything like that
[12:59:56] <IchGuckLive> even that will give you more then 15000 per second
[13:00:09] <IchGuckLive> what are you building
[13:00:45] <zbychuk> i am trying to build something like "mantis cnc 9.1"
[13:00:56] <zbychuk> my new hobby :)
[13:01:01] <zbychuk> i think
[13:01:22] -!- ravenlock has quit [Quit: Leaving]
[13:01:27] <IchGuckLive> so lowest available issues
[13:01:31] <zbychuk> maybe later i will build something more solid
[13:01:41] <IchGuckLive> at minimum price
[13:01:56] <zbychuk> yah, ok thanks
[13:02:01] <IchGuckLive> ehee are you in the world
[13:02:08] <IchGuckLive> where
[13:02:13] <zbychuk> Poland, Europe
[13:02:17] <IchGuckLive> NICE
[13:02:38] <IchGuckLive> you shoudt start at TR16x4 Trapez tread
[13:02:43] <IchGuckLive> cheep stuff
[13:02:56] <zbychuk> I want to widen my skils set
[13:02:58] <zbychuk> ok
[13:03:03] <IchGuckLive> and steüppers low price kit from china TB6560
[13:03:29] <IchGuckLive> there you can go below 200Euros in first place
[13:04:15] <IchGuckLive> but keep in mind there are good semi pros out for 399
[13:04:24] <IchGuckLive> out of the box
[13:04:55] <IchGuckLive> its hard work on self building
[13:05:28] <zbychuk> ok, thanks

[13:29:06] -!- dan2k3k4 has quit [Ping timeout: 255 seconds]
[13:30:35] <Fuchikoma> Depends on what you consider to be "poor latency" ;)
[13:31:10] <skunkworks_> my guess would be pentium 3/4 tranistion..
[13:31:30] <CaptHindsight> Fuchikoma: I'm referring to the issue that SpeedEvil mentioned ~1/2 hour ago
[13:32:14] <SpeedEvil> That's why I was saying 'in principle'
[13:32:26] <SpeedEvil> I'm really unsure - but it's going to be worse with integrated low-power stuff

[13:35:30] <Fuchikoma> Unless maybe that's a typo for "ms" which would be absolutely terrible
[13:35:59] <CaptHindsight> that's what I'm not sure of, maybe zbychuk can clarify
[13:36:37] <SpeedEvil> well, 25us to 18000us makes more sense
[13:37:02] <SpeedEvil> And 18ms is basically useless
[13:37:06] <Fuchikoma> It would, especially since 18000ns is actually LESS than 25us.
[13:39:15] <pcw_home> and 25 usec is good on an Atom (which may have hardware latencies in the 50 usec region)
[13:39:31] <CaptHindsight> I've only read about older integrated graphics mainboards having poor latency. I wonder if it was the drivers?
[13:40:32] <pcw_home> also older MBs had much lower memory --> video bandwidth
[13:42:27] <CaptHindsight> pcw_home: looks like 3.14 RTAI is working

[13:50:01] <CaptHindsight> pcw_home: have yet to find out later today. He has an APU and a R9 290 board. No driver yet for the R9, but I don't think many will use one for the Linuxcnc setup.

[16:25:40] <IchGuckLive> hi all B)
[16:26:11] <jthornton> zeeshan, any G code that uses spindle sync motion
[16:26:32] <jthornton> I think
[16:26:35] <zeeshan> jthornton: i'm trying to ensure my spindle is at speed before executing g01..
[16:26:37] <zeeshan> or g02
[16:26:42] <zeeshan> any linear/radial moves
[16:26:48] <zeeshan> i was really hoping it'd effect those
[16:27:07] <jdh> try it!
[16:27:58] <IchGuckLive> zeeshan:
http://linuxcnc.org/docs/html/man/man9/motion.9.html
[16:29:08] <jthornton> zeeshan, how long does it take to get your spindle up to speed
[16:29:20] <zeeshan> depends on rpm, but if im going from 400 rpm to 1200 rpm
[16:29:27] <zeeshan> about 2 seconds
[16:29:33] <zeeshan> i have a slow ramp on the vfd
[16:30:11] <zeeshan> motion.spindle-at-speed IN BIT Motion will pause until this pin is TRUE, under the following conditions: before the first feed move after each spindle start or speed change; before the start of every chain of spindle-synchronized moves; and if in CSS mode, at every rapid->feed transition.
[16:30:23] <zeeshan> so i guess any linear/arc move is covered
[16:30:26] -!- phantoxe has quit []
[16:30:27] <zeeshan> cause they are 'feed moves'

[17:56:26] <zeeshan> okay..
[17:56:28] <zeeshan> it seems to work
[17:56:45] <zeeshan> if it goes from 800 rpm to 1000 rpm, itll wait till it hits 1000 before going g01
[17:57:01] <zeeshan> but the thing is if it goes from 1000 rpm to 800 rpm, itll keep going
[17:57:14] <zeeshan> weird.
[17:57:51] <cradek> where are you getting your at-speed signal?
[17:57:52] <skunkworks_> what are you using to sense the spindle speed?
[17:57:59] <skunkworks_> heh
[17:58:00] <zeeshan> haha
[17:58:11] <zeeshan> at speed signal is from the encoder
[17:58:21] <skunkworks_> what hal bits?
[17:58:25] <cradek> encoders don't have at-speed
[17:59:23] <zeeshan> im using the near component
[17:59:33] <zeeshan> and comparing the signals spindle-cmd and spindle-velocity
[18:00:07] <zeeshan> spindle velocity comes from encoder.x.velocity
[18:00:21] <cradek> ok near
[18:00:26] <cradek> what are your near settings?
[18:00:43] <zeeshan> since my spindle-velocity is a small number that comes from the encoder
[18:00:52] <zeeshan> 70:1 ratio..
[18:00:59] <cradek> ??
[18:01:02] <zeeshan> so i do 70*1.05 (within 5%)
[18:01:10] <zeeshan> near.x.scale 73.5
[18:01:28] <zeeshan> that's really the only criteria
[18:01:53] <cradek> I don't understand why your spindle-velocity is off by a factor of 70
[18:02:11] <zeeshan> basically when spindle-cmd is 100rpm , spindle-velocity will output 1.428
[18:02:25] <zeeshan> which is off by a factor of 70
[18:02:27] <zeeshan> i'm not sure lol
[18:02:28] <cradek> usually a spindle should be scaled so one revolution is 1.0 in position, and then the velocity is in rps
[18:02:38] <zeeshan> my encoder.x.position-scale is set to 70
[18:03:16] <cradek> at 100rpm velocity should be 1.667 (100/60)
[18:03:44] <zeeshan> hmm
[18:04:08] <skunkworks_> what is the encoder?
[18:04:19] <zeeshan> 1 index pulse
[18:04:20] <zeeshan> 1 phase z
[18:05:46] <zeeshan> http://linuxcnc.org/docs/html/examples/spindle.html#_spindle_synchronized_motion_a_id_sec_spindle_synchronized_motion_a
[18:05:57] <zeeshan> i literally copied that to setup the encoder and sync motion

[18:06:06] <zeeshan> the only thing diffeerent is mine says 70 not 100
[18:06:11] <zeeshan> and the pins are different
[18:06:34] <zeeshan> and then i copied the spindle at speed section, and changed the near.0.scale to 70*1.05 = 73.5
[18:07:28] <cradek> 70 is not a multiple of 4 so it's really unlikely to be a correct scale
[18:07:48] <cradek> er oops, you only have one sensor, so it could be right
[18:07:52] <IchGuckLive> im off BYE
[18:07:57] -!- IchGuckLive has quit [Quit: ChatZilla 0.9.87 [Firefox 20.0/20130329043827]]
[18:07:58] <cradek> how many lines/whatevers are on your encoder/whatever?
[18:08:04] <skunkworks_> wouldn't the scale be set to 1?
[18:08:06] <zeeshan> its got 70 slots
[18:08:10] <skunkworks_> oh
[18:08:13] <zeeshan> skunkworks: no, then it doesnt work
[18:08:22] <cradek> doesn't it count on both edges?
[18:08:22] <zeeshan> because its trying to compare 100 and 1.48

[18:08:48] <zeeshan> i dont thinkso, from what i remember when configuring/testing syncro motion
[18:09:02] -!- sumpfralle has quit [Ping timeout: 245 seconds]
[18:09:05] <zeeshan> it only triggers when it goes from low to high
[18:09:08] <zeeshan> not high to low
[18:09:11] <skunkworks_> zeeshan, explain the encoder again.. How many channels? abz? az?
[18:09:13] <cradek> you're right
[18:09:17] -!- JLuc69__ has quit [Ping timeout: 260 seconds]
[18:09:30] <cradek> then seems like 70 is the right scale
[18:09:41] <zeeshan> skunkworks: one optical encoder that measures an index slot, and one optical encoder that measures 70 slots
[18:09:50] <skunkworks_> ok
[18:09:51] <cradek> you're confusing rpm/rps (60) and 70 (your scale)
[18:10:07] <cradek> I think
[18:10:11] <zeeshan> so spindle-velocity is output as RPS
[18:10:14] <zeeshan> i gotcha.
[18:10:16] <zeeshan> that would make sense!
[18:10:31] <cradek> if 1.0 in position is one rotation, then definitely the velocity output is rps
[18:10:58] <cradek> that's just how encoder scaling works, and is nothing special about rpm/rps/spindle

[18:21:23] <zeeshan> the main thing i want to get is a quick change morse taper adapter
[18:21:28] <zeeshan> so i can drill using the qctp
[18:21:36] <Jymmm> zeeshan: I was thinking vacuum cleaner hose
http://www.vacuumspot.com.au/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/h/s/hs.jpg
[18:21:48] <zeeshan> hmm that might work!
[18:21:50] <Jymmm> then you have spares too
[18:22:01] <Jymmm> cable tie it on
[18:24:48] <Connor> Vacuum cleaner hose might not work.. depends on the kind you get.. most won't compress...

[18:25:13] <zeeshan> just did some measurements of the two test runs, .95 => .9493, .9506, .85 => .8491, .8487, .75 => .7492, .7493, .5 => .,4970, .4962
[18:25:15] <zeeshan> thats so weird
[18:25:33] <zeeshan> the numbers are within a thou of each other
[18:25:49] <zeeshan> but the .5" diameter is off by 3-4 thou!
[18:26:00] <Connor> It's further out..
[18:26:05] <Connor> from the spindle..
[18:26:10] <archivist> built up edge
[18:26:10] <Connor> maybe run-out
[18:26:20] <zeeshan> it if was flexing
[18:26:25] <zeeshan> i'd think it'd be bigger, not smaller
[18:26:54] <Connor> you checked for backlash ?
[18:27:26] <zeeshan> yes
[18:27:29] <zeeshan> its within a thou
[18:27:35] <archivist> if it has poor finish it is a sign of built up edge on the tool
[18:27:45] <zeeshan> archivist: seems pretty nice!
[18:27:59] -!- patrickarlt has quit [Remote host closed the connection]
[18:28:05] <archivist> I have seen a nice finish from bue too
[18:28:17] <zeeshan> that is a brand new insert btw
[18:28:22] <Connor> Have you enabled backlash compensation to take the remaining out?
[18:28:28] <zeeshan> Connor: yes
[18:28:36] <archivist> lubricate while testing again
[18:28:44] <zeeshan> archivist: good idea!

[18:28:46] <zeeshan> i didnt think of that.
[18:28:48] <zeeshan> brb
[18:28:58] <zeeshan> i'm tired of making this steps btw
[18:29:01] <Connor> I would take a sprint pass too
[18:29:02] <zeeshan> wasting aluminum ;p
[18:29:07] <Connor> spring
[18:29:13] <jdh> or two
[18:29:19] <Connor> yup. or two.
[18:29:20] <zeeshan> yes, but the thing is
[18:29:23] <zeeshan> it's smaller then nominal!
[18:29:35] <zeeshan> so the spring pass will eat even more material if anything
[18:29:46] <jdh> but it will be prettier.
[18:29:51] <jdh> and that's why we have tolerances.
[18:30:02] <archivist> look at the tip, anything stuck on it?
[18:30:07] -!- anth0ny has quit [Quit: anth0ny]
[18:30:10] <zeeshan> yes, an upcoming project requires bearing fits
[18:30:11] <Connor> once you can get it making them consistent.. you can the compensate for that..
[18:30:15] <zeeshan> so it needs to be within a couple tenths
[18:30:23] <zeeshan> if this thing is really that off, ill just program it to be 1 thou bigger
[18:30:24] <jdh> is your zero good? spindle/way alignment?
[18:30:26] <zeeshan> so i can sand it to size
[18:30:39] <zeeshan> jdh, yes zero is good
[18:30:48] <zeeshan> i havent checked spindle/way alignment
[18:30:56] <zeeshan> it could actually be that
[18:31:01] <zeeshan> since it's consitently off in the same location

[23:16:02] <JesusAlos> CaptHindsight: yes 0,1,2 and Estop inputs. 3 axis step direction outputs and 0-10V for spindle

[23:41:39] <LeelooMinai> I am making a place in my room for cnc machine and floor drill - it will be just 6x 10ft long cedar 2 by 6. Not sure about the weights, but the floor drill is a medium size I guess, and the cnc will weight maybe, hmmm, 60kg? Should I worry I put those two by the wall?

[23:42:15] <LeelooMinai> I guess people put heavy aquarium and such in rooms... so maybe I should not worry too much?

[23:45:04] <sharpen048> ok CaptHindsight i found that the hal file isnt opening buttons
[23:45:58] <LeelooMinai> Hmm found spec for the drill - 151 pounds - I guess that's nothing I should worry about, right?
[23:46:14] <JT-Shop> how much do you weigh?
[23:46:31] <LeelooMinai> No idea:)

[23:47:36] <LeelooMinai> But it may be average, not point load (?)
[23:47:55] <LeelooMinai> Well, it must be, because otherwise a person would make a hole in the floor...
[23:48:01] <JT-Shop> heh
[23:48:20] <JT-Shop> jump up and down and if the floor doens't collapse your oke

[23:48:43] <zeeshan> whats the point of the thing that goes below the insert?
[23:48:47] <LeelooMinai> Unfortunatelly those 2x6 cedar planks I have will be parallel to joists not across them
[23:48:49] <zeeshan> i never had this on my old tool holders
[23:49:27] -!- pjm has quit [Ping timeout: 244 seconds]
[23:49:41] <JT-Shop> it provides support for the insert and when you crash you can replace it
[23:50:09] <zeeshan> so its a bumper
[23:50:11] <LeelooMinai> btw, did anyone here do something for cnc (say small table with inserts) from concrete?
[23:50:11] <zeeshan> :D
[23:50:22] -!- GlennS has quit [Ping timeout: 244 seconds]
[23:50:51] <LeelooMinai> I read about kitchen countertops people make from concrete and though if this could be used somehow for cnc table - as it's dirt cheap
