[02:16:37] <Deejay> moin
[03:43:41] <Loetmichel> mornin'
[05:59:34] <IchGuckLive> hi all B)
[05:59:54] <IchGuckLive> has been a bussy night here and as the germans tok over all disapeared
[06:02:11] <IchGuckLive> cool the logs show 2 new nicks choining the channel and discussing on no knoligbase thats a pretty cool thing
[06:03:35] <IchGuckLive> ah there he is
[06:03:41] <IchGuckLive> hi BellinganRoy
[06:04:08] <IchGuckLive> welcome to the channel
[06:04:32] <IchGuckLive> nice talk to the android guy over plasma
[06:06:34] <IchGuckLive> BellinganRoy: ?
[06:09:07] <BellinganRoy> Uh thanks IchGuckLive
[06:09:46] <IchGuckLive> you diddent ask on self help needed
[06:09:52] <IchGuckLive> im in germany
[06:10:24] <IchGuckLive> if you got a queastion to us yust ask as many read the loggings
[06:11:26] <BellinganRoy> Ok thank you
[06:12:22] <BellinganRoy> I was planning in building from "scratch" my own 5 axis cnc (milling no router) and... I've encountered linuxcnc... i plan to use the beagle bone black, so .. I think i'll be around here for quite a long
[06:12:45] <SpeedEvil> :)
[06:12:56] <SpeedEvil> How scratch?
[06:13:07] <SpeedEvil> Are we talking broken chunks of cast iron and a furnace?
[06:13:22] <IchGuckLive> oh nice this might be fun
[06:13:31] <IchGuckLive> what size do you try to go
[06:13:54] <BellinganRoy> this will be SCRATCH, for "scrathc" i'm referring that... uhm only the metal slide, stepper motor and few electronics..
[06:14:02] <IchGuckLive> http://www.youtube.com/watch?feature=player_embedded&v=R1DCXe9t3UE
[06:14:34] <IchGuckLive> BellinganRoy: what is the goal the mashine is going to do
[06:15:05] <BellinganRoy> The first I think will be quite small, i plan to use it mostly for metal parts, 30cm x 30 c, on x,y axis, Z ... 15 cm will be enought I think...
[06:15:32] <SpeedEvil> you're buying the XY?
[06:15:50] <IchGuckLive> dont forget the tool length on XYAB movement to compensate on Z 15 is to small
[06:16:04] <BellinganRoy> yes yes I'm referring to "net" working space...
[06:16:40] <IchGuckLive> meatel part relates on a 8point fixing all axis so be shure to mak it stiff
[06:16:54] <BellinganRoy> but I'm really not sure to start with a bigger one for wood only...
[06:17:36] <BellinganRoy> Yes I plan to use nema 34 motor, full lenght (too lazy to use a reductor)
[06:17:42] <IchGuckLive> this will give you more space and know how
[06:17:54] <BellinganRoy> The wood one will be nema 23 ecc
[06:17:59] <IchGuckLive> i woudent go on Nema34 first
[06:18:11] <BellinganRoy> For the metal one ?
[06:18:19] <IchGuckLive> a Nema 34 on Gear > 10 is best
[06:18:51] <BellinganRoy> Sorry I've not understood, you mean a smaller one with reduction gear is better ?
[06:18:59] <IchGuckLive> i pull a 800kg Plasma XYZ on a Nema23 3Nm at 30:1 for now 8month at 8hr dayly
[06:19:14] <BellinganRoy> ! very nice !
[06:19:16] <IchGuckLive> the gear takes the force
[06:19:22] <BellinganRoy> witch motor is it ?
[06:19:29] <IchGuckLive> so its a very smooth stepper run
[06:19:54] <IchGuckLive> http://www.pro-tos.de/shop/Schrittmotoren/
[06:20:06] <BellinganRoy> the problem is that with alluminium I can't go too slow, or else the alluminium will stick on the blade
[06:20:26] <IchGuckLive> i can go 10m/min
[06:20:36] <IchGuckLive> on a 5i25
[06:20:51] <IchGuckLive> at 0.01mm precission
[06:21:03] <BellinganRoy> those are some serious motor, and with very good price too, thank you!
[06:21:13] <IchGuckLive> with no step loss at 8hr shift at 5m/min work speed
[06:21:37] <BellinganRoy> yes this will be enough for alluminium too...!
[06:21:44] <IchGuckLive> if you plan that mashine do it at highly parts
[06:22:02] <BellinganRoy> the http://www.pro-tos.de/shop/Schrittmotoren/Schrittmotor-24H291-42-4-IP-3-Nm.html is marvellous
[06:22:09] <IchGuckLive> where are you in the woorld
[06:22:30] <IchGuckLive> http://foengarage.de/mesa_elek.jpg
[06:22:41] <BellinganRoy> Italy, Frascati near Rome, but I've been some time in Amburg.
[06:22:44] <IchGuckLive> this is the cabinett i build on mine
[06:23:03] <BellinganRoy> good looking!
[06:23:19] <IchGuckLive> i only use the leadshine drivers
[06:23:31] <IchGuckLive> the M880A will fit all you need
[06:23:40] <IchGuckLive> at 70V
[06:23:55] <IchGuckLive> for your wod consider the M542 at 48V
[06:23:55] <BellinganRoy> thank you! for the motor I think the 24H291 is a wonder...
[06:24:21] <IchGuckLive> agree at 39Euros it is a hell of force
[06:24:43] <IchGuckLive> i got a 30:1 worm on it at rackpinon movement
[06:24:56] <BellinganRoy> K
[06:24:59] <IchGuckLive> that pulls the 800kg
[06:25:21] <BellinganRoy> very notable...
[06:26:03] <IchGuckLive> so calculation is 400Steps/rev stepper on 30:1 =12000Steps/rev Pinion
[06:26:14] <BellinganRoy> my goal is to "rebuild" old cars chassis, like vintange bentley ecc
[06:26:18] <IchGuckLive> at 12Teeth T10
[06:26:26] <IchGuckLive> its 120mm/rev
[06:26:31] <BellinganRoy> K
[06:26:40] <IchGuckLive> so 12000 / 120
[06:26:49] <IchGuckLive> =100 Steps per mm
[06:26:56] <IchGuckLive> perfect fit at 0.01
[06:27:09] <BellinganRoy> docs says is a 200 steps/rev
[06:27:13] <IchGuckLive> full speed max torque at best steprate
[06:27:33] <IchGuckLive> BellinganRoy: at half stepping its double
[06:27:45] <BellinganRoy> don't you loose power ?
[06:27:48] <IchGuckLive> you need a microstep to get best speed
[06:28:05] <IchGuckLive> no power loss on up till 178
[06:28:08] <IchGuckLive> 1/8
[06:28:23] <IchGuckLive> but best to go low
[06:28:25] <BellinganRoy> oh good, I've just used pre builded cnc machine from Bieffe Work
[06:28:32] <IchGuckLive> so 1/2 is best to considder
[06:29:22] <BellinganRoy> sorry biesse http://www.biesse.com/it/it/rover/rover_k
[06:29:57] <IchGuckLive> nice i worked a year for barrufaldi punch system in ferrera
[06:30:02] <BellinganRoy> so I'm not well prepared on "low level" mechanical stuff
[06:30:11] <BellinganRoy> Ma allora parli Italiano ?
[06:30:31] <IchGuckLive> No italian only brugola
[06:30:36] <BellinganRoy> ok
[06:30:58] <IchGuckLive> all on english
[06:31:23] <BellinganRoy> for what did you use the plasma cutter ?
[06:31:35] <IchGuckLive> you can get the mesa cards in austria
[06:31:47] <BellinganRoy> oh and by the way I'm also a C++ programmer, so I'll also like to see the code and maybe give an hand!
[06:32:03] <IchGuckLive> http://www.schweden-feuer.de/feuersauelen.htm
[06:32:19] <IchGuckLive> BellinganRoy: its most in python
[06:32:21] <BellinganRoy> At I've thought to use the beagle bone black, i've seen some good shields
[06:32:44] <BellinganRoy> AMAZING http://www.schweden-feuer.de/Feuseu_lg/kandins_on_fire.htm
[06:33:01] <IchGuckLive> ;-)
[06:33:40] <BellinganRoy> I think I'll take one for my sister http://www.schweden-feuer.de/Feuseu_lg/feuKor_hex_on_fire.htm, if she will ever have a garden... -.-
[06:33:51] <IchGuckLive> you shoudt realy considder to go for a better electronic output as on beagle boane
[06:34:15] <IchGuckLive> the 3d printers are mosst on 0.254mm precission this will not fit your need
[06:34:48] <IchGuckLive> i got about 250 mashines running on linuxcnc
[06:36:01] <BellinganRoy> o.O
[06:36:06] <BellinganRoy> serious number...
[06:36:25] <IchGuckLive> it coudt be mutch more i diddent considder all
[06:37:21] <IchGuckLive> this are most at 80% education mashines with no production at all also not stable to mill wood
[06:37:49] <BellinganRoy> What do you mean not stable for wood ?
[06:38:18] <IchGuckLive> hi Patoche
[06:38:29] <IchGuckLive> BellinganRoy: http://www.youtube.com/user/magic33de/videos
[06:38:40] <Patoche> Hi
[06:38:45] <BellinganRoy> Ciao
[06:39:04] <IchGuckLive> http://www.youtube.com/watch?v=QEfbrh4maqM
[06:39:20] <IchGuckLive> Patoche: if you got a question yust ask
[06:39:52] <IchGuckLive> BellinganRoy: http://www.youtube.com/watch?v=WZotjleEtj0
[06:40:07] <BellinganRoy> subscribed to the channel!
[06:40:14] <IchGuckLive> foam and rubbershape plastic
[06:40:48] <IchGuckLive> oh you will be not lucky i plan to go to the outback for years and will trar down the channel soon
[06:41:06] <BellinganRoy> soo i'll download it
[06:41:24] <IchGuckLive> its coman information from our wikipedia
[06:41:26] <IchGuckLive> so no need
[06:41:40] <IchGuckLive> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Simple_LinuxCNC_G-Code_Generators
[06:42:12] <IchGuckLive> hi SquirrelCZECH
[06:42:25] <BellinganRoy> so you suggest me the mesa card...
[06:42:36] <IchGuckLive> yes i am
[06:42:54] <IchGuckLive> dont use a parport for your planed 5axis
[06:43:08] <BellinganRoy> Ok I'll study the site, no no parport absolutly not!
[06:43:21] <IchGuckLive> if you can relie on a 5i25 7i76
[06:43:46] <SquirrelCZECH> IchGuckLive: hi? :)
[06:44:10] <IchGuckLive> in italy there are also very good boards get you a mini itx D525Mw as they are the best on your plans
[06:44:19] <BellinganRoy> In reality I'm thinking about an ethernet based card
[06:44:28] <IchGuckLive> SquirrelCZECH: weather is hot as the russion high is over you ?
[06:44:44] <IchGuckLive> oh
[06:44:47] <SquirrelCZECH> he?
[06:44:52] * SquirrelCZECH is not getting it
[06:44:55] <IchGuckLive> Ethernet there is a 7i76E out
[06:45:07] <IchGuckLive> and on your plans go for 7i80
[06:45:52] <IchGuckLive> SquirrelCZECH: its very hot in the east after the disaster rain
[06:47:04] <BellinganRoy> IchGuckLive: sorry for what is used the FPGA on those board ?
[06:47:28] <SquirrelCZECH> IchGuckLive: and reason why are you teling me this?
[06:48:03] <IchGuckLive> BellinganRoy: http://www.mesanet.com/fpgacardinfo.html SCROLL down to the 7i80
[06:48:17] <IchGuckLive> SquirrelCZECH: its still raining here
[06:48:23] <BellinganRoy> Yes i'm here
[06:50:03] <SquirrelCZECH> IchGuckLive: I still do not get the point... nevermind
[06:50:04] <IchGuckLive> BellinganRoy: its all then hardware so pc and net and all stuff is not infecting your system
[06:50:29] <BellinganRoy> Ok
[06:50:36] <IchGuckLive> SquirrelCZECH: ok only on info if it is better weather on your home
[06:50:45] <SquirrelCZECH> fucking sun
[06:50:47] <SquirrelCZECH> try to guess :)
[06:51:36] <IchGuckLive> BellinganRoy: you are asking for best input thats what i told you
[06:51:57] <IchGuckLive> if you plan to go that way you need a good setup
[06:52:09] <BellinganRoy> Yes those are really good board!
[06:52:17] <BellinganRoy> 56 Years ahead beagle bone stuff
[06:52:40] <IchGuckLive> if you think your beagle bone can do it go for it
[06:52:59] <IchGuckLive> but first test on software to drive it
[06:53:06] <BellinganRoy> 7i76E outhisne for me, it has spindle control too..
[06:53:15] <IchGuckLive> yes
[06:55:12] <BellinganRoy> For the spindle if I can ask, I've seen those https://www.buildyourcnc.com/Item/spindle-inverter-2!2kw-spindle-vfd
[06:55:30] <BellinganRoy> or a 1.5Kw too there is
[06:55:48] <IchGuckLive> yes the huanyan works fine
[06:56:16] <IchGuckLive> lots of people use them
[06:56:20] <BellinganRoy> thank you, rpm are driven by the board so . good
[06:56:41] <IchGuckLive> yes but consider its made for RPM over 10k
[06:57:04] <BellinganRoy> yes, for metal those are the rpm
[06:59:30] <SquirrelCZECH> electronics suggestions?
[06:59:44] <SquirrelCZECH> <BellinganRoy> 56 Years ahead beagle bone stuff | that refers to what? :)
[07:00:04] <IchGuckLive> 5-6
[07:00:12] <SquirrelCZECH> I mean for what board? :)
[07:02:22] <IchGuckLive> ok im off BYE
[07:03:42] <BellinganRoy> Oh sorry, I'm referring to Mesa board vs ... http://blog.machinekit.io/p/hardware-capes.html
[07:24:26] <SquirrelCZECH> why
[07:24:32] <SquirrelCZECH> why so many boards likes the small stepsticks ?
[07:31:35] <CaptHindsight> small, low cost and a good for for toys and consumer appliances
[07:31:49] <CaptHindsight> for/fit
[07:35:56] <SquirrelCZECH> yeah, toys
[07:36:14] <SquirrelCZECH> but I don't like it so much on big toys like reprap
[07:41:34] <BellinganRoy> Sorry do someone has info about that 1.5kw spindle ? I've seen it on a lot of site but no one has the name ... https://www.buildyourcnc.com/Item/spindle-inverter-1!5kw-spindle-novfd
[07:41:54] <BellinganRoy> Or here http://www.ebay.com/itm/80MM-PRO-1-5KW-WATER-COOLED-SPINDLE-MOTOR-ER11-3-175-6-ENGRAVING-MILL-GRIND-A-/130806056227?talgo=origal&tfrom=380519544899&ttype=price&tpos=unknow&ssPageName=STRK:MESE:IT
[08:00:29] <jdh> did you buy it?
[08:03:49] <BellinganRoy> no I'm planning
[08:05:24] <jdh> I'd look for one that comes with the VFD also.
[08:05:43] <BellinganRoy> yes I've just linked the ad for the motor for clarity
[08:05:52] <BellinganRoy> the bundle is way cheeper!
[08:12:50] <archivist_herron> BellinganRoy, I did make a scratch build 5 axis
[08:13:40] <BellinganRoy> archivist_herron: good!
[08:14:33] <archivist_herron> used a lathe bed for Z, and an XY frm a tool setting machine, and A is a vertex, B a Soba
[08:16:09] <BellinganRoy> I followed the first part, but I don't understand what is a vertex and Soba, il check out
[08:16:51] <archivist_herron> they are rotary tables, added steppers to them
[08:17:12] <archivist_herron> the spindle is the old lathe headstock
[08:17:14] <BellinganRoy> ah! understood...
[08:18:44] <archivist_herron> lifted the head of the lathe base added slides then mounted the head onto a plate, moved the leadscrew to a new location
[08:19:11] <archivist_herron> fugly http://www.collection.archivist.info/archive/DJCPD/PD/2009/2009_05_27_cnc_making_pin_wheel/IMG_0252.JPG
[08:20:10] <archivist_herron> so look at old machinery and think what the lumps could do for you
[08:20:19] <BellinganRoy> I don't get well the whole machine axis movement
[08:20:40] <BellinganRoy> but yes, starting and "powering up" an old machine is very good idea...
[09:06:46] <tjtr33> jthornton, saw this last nite, the reverse trike is 6" wider than the PCX he's chasing https://www.youtube.com/watch?v=jubFBRx0a3Q
[09:11:41] <FinboySlick> tjtr33: But that's in asia. Around here, the driver's butt is 6" wider than the bike ;)
[09:13:10] <tjtr33> haha john deer tractor seat clearance, yeah Krung Thep traffic is nuts!
[09:14:24] <FinboySlick> And before you all think I'm making fun of fat Americans, I'm Canadian!
[09:14:31] <FinboySlick> We're fat too!
[09:16:35] <SpeedEvil> Either choose to be run over accidentally, or follow the usual expected rules of the road.
[09:18:19] <CaptHindsight> it doesn't seem to have much of an impact on population control there
[09:19:37] <Loetmichel> SpeedEvil: on the contrary: they are proud of being "good drivers" and proof that by "near accidents avoided per hour"
[09:20:07] <CaptHindsight> especially when you see entire families on one scooter
[09:21:12] <Loetmichel> they should driver in germany: instant death
[09:21:37] <Loetmichel> because german drivers obey ruules (more or less) and expect the othters top obey them as well
[09:22:07] <Loetmichel> german proverb "rechts ist frei, links zahlt die versicherung"
[09:22:18] <FinboySlick> Loetmichel: Around here, one of the first rules of driving is not to expect other drivers to obey the rules.
[09:22:36] <Loetmichel> (to the right there are no cars, to the left dosent mind, its paid by the insurance"
[09:22:53] <CaptHindsight> I hear Germany is becoming more like North America in that respect
[09:23:15] <Loetmichel> FinboySlick: right, the first rule is that.
[09:23:25] <Loetmichel> but the least ppl here follow THAT rule ;)
[09:24:25] <Loetmichel> and you HAVE to be certain that noone changes lanes when driving on the autobahn without looking in the rearview miroor, or you get killed when driving 210kmh straight
[09:24:51] * Loetmichel had some very close encounters with the old grannys that disobeyed that rule
[09:25:25] <Loetmichel> ... to decellerate 2 tons of car from 200++ to 90kmh in less than 50meters is an experience to say the least ;-)
[09:25:35] <CaptHindsight> is it still illegal to pass on the right on the autobahn?
[09:25:41] <Loetmichel> it is
[09:25:58] <Loetmichel> and that is wise rule
[09:26:06] <Loetmichel> at the usual speeds
[09:26:10] <tjtr33> imagine the subtitles for this one intensely funny http://biertijd.com/mediaplayer/?itemid=41302
[09:27:06] <CaptHindsight> that is a classic
[09:27:49] <FinboySlick> The splash at the end suggests that there was water down that hole, I hope for his sake that there was enough.
[09:28:03] <CaptHindsight> I like how they guys just get back in the truck
[10:16:04] <skunkworks_> https://groups.yahoo.com/neo/groups/mach1mach2cnc/conversations/messages/145516
[10:54:15] <zeeshan> is there something wrong with the tool table in linuxcnc?
[10:59:02] <Loetmichel> zeeshan: noide, never used it ;-)
[10:59:05] <Loetmichel> no idea
[10:59:10] <zeeshan> ;/
[10:59:53] <archivist> it works for me on my lathe
[11:00:20] <zeeshan> archivist: i'm confused by it..
[11:00:30] <zeeshan> so when i put my rh turning tool and make it tool 1
[11:00:46] <zeeshan> i use the tool offset touchoff for both x and z
[11:00:57] <zeeshan> then using the mdi, i set it to tool 2
[11:01:11] <zeeshan> and do tool offset touchoff for both x and z again..
[11:01:16] <zeeshan> is this the correct procedure?
[11:01:42] <archivist> erm what...why doing it a second time with the same tool
[11:01:49] <zeeshan> sorry
[11:01:53] <zeeshan> i change the tool to a facing tool
[11:01:57] <zeeshan> (tool 2)
[11:02:04] <zeeshan> tool 3 is a lh turning tool
[11:02:04] <zeeshan> etc
[11:02:52] <archivist> I edit the table there is a magic command to store offsets in later table entries
[11:03:09] <zeeshan> thats another thing
[11:03:16] <zeeshan> i want tool 1 to be 0 0 0 for the offsets
[11:03:22] <zeeshan> but everytime i use the touch off thing
[11:03:27] <zeeshan> it resets to some random values..
[11:03:41] <archivist> which touch off!
[11:03:54] <zeeshan> when you press touch off
[11:04:09] <zeeshan> it asks you which type (g54, something something, tool offset)
[11:04:13] <zeeshan> i select tool offset
[11:04:18] <archivist> dont
[11:04:35] <zeeshan> can you please describe how you set yours up
[11:04:52] <archivist> tool1 sets the basic position, only do that for 2 and up
[11:05:04] <zeeshan> thats what im trying to say though
[11:05:11] <zeeshan> i've already set tool 1 to 0 manually
[11:05:23] <archivist> so you dont up date the table for tool one
[11:05:24] <zeeshan> then i do a tool change to tool 2, and change the cool, and touch off again
[11:05:44] <zeeshan> when i do that, tool 1 automatically changes from 0 0 0 to some random values on its own..
[11:08:06] <archivist> g54 is wrong see http://www.linuxcnc.org/docs/2.4/html/gcode_main.html#sec:G10-L1-Set-Tool-Table
[11:08:16] <zeeshan> grrr
[11:08:18] <zeeshan> im not using g54
[11:08:36] <archivist> what you said <zeeshan> it asks you which type (g54, something something, tool offset)
[11:09:19] <zeeshan> http://www.linuxcnc.org/docs/2.4/html/lathe_lathe-user.html#r1_3_1
[11:09:25] <zeeshan> im using these instructions
[11:09:31] <zeeshan> for both X and Z
[11:10:01] <zeeshan> step #2 "set current tool to TnM6, where n is the tool number" <- i do this using the mdi
[11:10:05] <zeeshan> i type T2 M6
[11:10:27] <archivist> I edit the table and dont futz with that method :)
[11:10:30] <zeeshan> then step 5 is what i was talking about
[11:10:38] <zeeshan> yes, but when you use that method for tool 2
[11:10:45] <zeeshan> tool 1 will automatically get over-written for some reason
[11:10:47] <zeeshan> !! :P
[11:11:37] <zeeshan> archivist: heres another question for you
[11:12:05] <zeeshan> when you are using a cam software to generate your g-code, and you have specified in the cam software where the "tool tip" is based on the tool geometry
[11:12:18] <archivist> the first paragraph contradicts itself
[11:12:31] <zeeshan> is it still necessary to use the tool compensation command
[11:14:14] <zeeshan> my cam outputs something like this during a tool change
[11:14:16] <zeeshan> N0030 T01 M06 N0040 G43 H00
[11:14:32] <zeeshan> whoops i mean H01
[11:14:35] <zeeshan> not H00
[11:14:49] <cradek> that looks fine
[11:15:31] * zeeshan is asking all these questions
[11:15:41] <zeeshan> cause i finally have to build something where tolerances matter
[11:16:02] <zeeshan> i'm thinking of making a simple part with a few steps on it
[11:16:10] <zeeshan> and changing tools in between and seeing whats up
[11:16:27] <zeeshan> and then also throwing a radius between the steps and using a radius gauge to measure
[11:16:31] <zeeshan> if its doing it right
[11:23:00] <dr0w> I'm considering clocking lathe spindle rpms with hall effect/neodymium magnet. Does this method offer enough resolution to do threading?
[11:23:30] <zeeshan> depends on the number of slots in your trigger wheel :P
[11:23:50] <archivist> dr0w, and you need an index pulse
[11:25:07] <dr0w> I'm mourning the fact I'm pretty sure I chucked a nice encoder wheel from dot matrix printer, when printers were built like tanks :(
[11:25:26] <archivist> make one
[11:26:21] <archivist> not too hard to make something like http://www.collection.archivist.info/searchv13.php?searchstr=starturn+encoder
[11:27:09] <dr0w> is that one optical then?
[11:27:37] <archivist> yes
[11:28:13] <archivist> just simple slotted optos on a mount
[11:28:45] <zeeshan> i have some extra trigger wheels for sale :P
[11:28:55] <zeeshan> actually ill keep em
[11:28:58] <zeeshan> you never know when you need em
[11:29:59] <dr0w> cool
[11:30:13] <archivist> I made one for the mill so it can hob and it seems I finally got an order for a couple of gears so time to put it on the machine
[11:30:43] <asah> anyone working with brushless dc / AC servos and not wiring direct from motor to amp? can I push the phases through terminal blocks and be ok?
[11:30:55] <SpeedEvil> asah: sure
[11:30:58] <SpeedEvil> If properly rated
[11:31:20] <PetefromTn_> afternoon folks.
[11:31:34] <asah> they are huge, and rated for the DC servos that used to be on here running at 380V
[11:31:44] <asah> I am running at 170
[11:31:49] <PetefromTn_> asah what machine?
[11:31:55] <asah> my maho 400
[11:32:00] <PetefromTn_> aah. sweet.
[11:32:24] <PetefromTn_> my motors are AC servos and are direct wired from amps so I cannot help you.
[11:32:38] <asah> you are using 8i20s right?
[11:32:42] <asah> for your amps?
[11:32:50] <PetefromTn_> no 5i25/7i77 combo.
[11:32:57] <asah> what is the amp?
[11:33:12] <asah> are you doing analog voltage out to some other amps?
[11:33:14] <PetefromTn_> the motors and drives are all made by Teco I bought them brand new from Machmotion.
[11:33:21] <asah> ah, ok.
[11:33:41] <PetefromTn_> the motors are matched to the servos from the seller.
[11:34:04] <asah> my cables are pretty heavy guage, the connection to the spade clips on the 8i20 is going to be interesting.
[11:34:25] <asah> it takes forever to back solder with my little iron. =)
[11:34:51] <asah> anyone jumping encoder leads through terminal blocks?
[11:34:57] <PetefromTn_> not familiar with the 8i20 but why are you needing heavy gauge wires to the board?
[11:35:07] <asah> that is probably more sketchy
[11:35:21] <asah> the 8i20 is the power amplifier
[11:35:46] <asah> needs to push 17 amps current, more in peaks.
[11:36:07] <PetefromTn_> aah okay.
[11:38:03] <PetefromTn_> looking at the pics on Mesanet of the 8i20 it appears there are some plug in connections for the high voltage wires along one side can you just get the right connectors or what?
[11:39:02] <asah> It has been a long time since I worked on cars ( refurbed a bunch of my first car when I was 16) but I feel like car rebuilders must feel. These retrofits have so many details! on and on. =)
[11:39:25] <asah> got my project out in the shop I spend my nights and weekends hacking on. =)
[11:39:36] <PetefromTn_> Oh yeah man there is always something you need to get or figure out. it seems like it never ends.
[11:39:59] <asah> I have the connectors ok. they just seem like they are underkill for this kind of connection.
[11:40:11] <asah> but I shall defer to pcw.
[11:40:19] <asah> he actually knowing what he is talking about.
[11:40:20] <PetefromTn_> I am just so pleased that my machine is working and that it is reliable every time I turn it on now.
[11:40:20] <asah> =)
[11:40:30] <PetefromTn_> he sure as hell does..
[11:40:33] <asah> I feel like I am close. =)
[11:40:36] <asah> must be a nice feeling.
[11:40:58] <asah> I have much of my electronics back in and mounted nicely.
[11:41:02] <PetefromTn_> oh don't worry it is still not finished but I use it every day now. Still need to finish up the toolchanger and spindle feedback.
[11:41:06] <asah> now rerouting the wiring.
[11:41:28] <asah> what gui do you uese?
[11:41:46] <PetefromTn_> I swear building a retrofit on a machine that was ALREADY a cnc is so much easier than one that is not its not even funny.
[11:41:59] <PetefromTn_> just axis simple with some add ons.
[11:42:39] <asah> I appreciate more and more the level of effort that went into building this thing.
[11:42:41] <PetefromTn_> I just finished machining some parts a couple minutes ago.
[11:42:45] <asah> 30 years ago.
[11:42:59] <PetefromTn_> I hear they are nice yet elaborate...
[11:43:14] <asah> Ill be able to remove like 70% of the wiring and components.
[11:43:42] <asah> this nice big relay board is going away. and the 7 different transformers.
[11:43:48] <asah> =)
[11:43:48] <PetefromTn_> LOL its so funny you say that I cannot believe how much less stuff is inside the electronics cabinet now after the major retrofit it done.
[11:44:16] <asah> I am seriously considering just making a small box, separated from the machine to put it all in.
[11:44:16] <PetefromTn_> it looks almost naked where before it was packed full of SCHTUFF..
[11:44:32] <IchGuckLive> hi all B)
[11:44:49] <asah> do some big harting connectors in between that and the mill. would be pretty sweet on shop real estate.
[11:45:07] <PetefromTn_> I need to send my blown 7i77 card back to Mesanet to get it repaired so I have another 5i25/7i77 setup for backup or if I want to build another machine at some point.
[11:45:11] <IchGuckLive> harting 48 is quite good
[11:45:25] <PetefromTn_> hey ich.
[11:45:33] <IchGuckLive> ;-)
[11:45:33] * Loetmichel is just testing his addiction against his lazyness... i forgot the E-cig in the car outside an hour ago... so far: lazyness wins ;-)
[11:46:13] <asah> We use those connectors in robotics all over the place.
[11:46:17] <asah> really nice!
[11:46:30] <IchGuckLive> agree
[11:46:32] <PetefromTn_> not familiar with them
[11:46:49] <Jymmm> Loetmichel: What do you mean "THE"? I think you forgot a 'M' at the end ;)
[11:47:19] <Loetmichel> hrhr
[11:47:20] <IchGuckLive> anonimasu: did you get the thcud fake running
[11:47:25] <asah> example: http://www.harting.com/uploads/pics/Harting_HanModular_03.jpg
[11:47:33] <Loetmichel> no, at the moment i have just one cig operational
[11:47:37] <asah> hardcore ip67 rated power and signal.
[11:47:41] <PetefromTn_> mmmm chunky!
[11:47:43] <asah> tons of configurations.
[11:47:45] <CaptHindsight> http://www.ustream.tv/channel/iss-hdev-payload a bandwidth hog but it's an nice view
[11:47:53] <Jymmm> Loetmichel: burned out all the others?
[11:47:58] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=15154 <- this one
[11:48:10] <IchGuckLive> CaptHindsight: you are the new starman
[11:48:13] <Loetmichel> no, just not charged/ laying around
[11:48:13] <Lathe_newbie> anyone here experience with omega belt drives?
[11:48:58] <IchGuckLive> Lathe_newbie: they got self stiffness so keep your access to the fixed side
[11:49:03] <PetefromTn_> BIG BLUE MARBLE!
[11:49:08] <asah> nice!
[11:49:39] <Lathe_newbie> IchGuckLive: i wanna use them for a tripod or hexapod
[11:49:58] <PetefromTn_> LOL I am gonna go outside and wave let me know if ya see me
[11:50:26] <CaptHindsight> PetefromTn_: try using a mirror :)
[11:51:02] <PetefromTn_> Naah you don't wanna see my reflection anymore than I do HEHEHE... DOH!
[11:51:04] <IchGuckLive> Lathe_newbie: will work fine
[11:51:32] <IchGuckLive> PetefromTn_: im on a blend now with marble
[11:51:39] <IchGuckLive> shout i color it blue
[11:51:52] <PetefromTn_> sure man have a blast
[11:52:41] <jdh> can't you just snort the nicotine liquid or shoot it up?
[11:53:05] <Jymmm> jdh: It's not the chemical addition, its the mental one.
[11:53:49] <Lathe_newbie> IchGuckLive: i think for short distances its not a big problem to get the belt stiff enough
[11:53:54] <PetefromTn_> yeah man like I GOTTA HAVE MY JELLY DONUTS LOL!!
[11:54:37] <CaptHindsight> PetefromTn_: when do the kids start back to school in your neck of the woods?
[11:54:50] <PetefromTn_> already did.
[11:55:00] <PetefromTn_> about two weeks ago actually.
[11:55:08] <CaptHindsight> wow, how long did they have off?
[11:55:22] <PetefromTn_> a couple months I guess not sure really.
[11:55:22] <jdh> I took my daughter back to school Friday. Empty nest again!
[11:55:51] <PetefromTn_> I kinda miss em but I get more done when they are in school so it is a mixed bag.
[11:57:21] <CaptHindsight> Lathe_newbie: have a link to the drives?
[11:58:02] <Jymmm> PetefromTn_: https://www.youtube.com/watch?feature=player_detailpage&v=a77Dw3tNv8o#t=82
[12:00:46] <Tom_itx> whyz that a secure link?
[12:00:59] <PetefromTn_> LOL yeah man that guys pretty funny.
[12:01:01] <jdh> so the NSA can't watch you stream it
[12:01:34] <Tom_itx> they're sitting there laughing at you if you believe that
[12:01:37] <PetefromTn_> Well I gotta get some more machinin' done here before I gotta go get my kids from school. Talk later folks!
[12:01:42] <IchGuckLive> PetefromTn_: http://foengarage.de/marble_blue.png
[12:01:46] <IchGuckLive> blue marble
[12:02:00] <Tom_itx> PetefromTn_, cnc's run themselves
[12:02:04] <PetefromTn_> whaddahell is that?
[12:02:14] <Jymmm> Tom_itx: Most all of google links are now SSL based.
[12:02:19] <PetefromTn_> Tom_itx Sure do when you have a WORKING TOOLCHANGER LOL
[12:02:23] <IchGuckLive> a socket for a dragon
[12:02:55] <IchGuckLive> let me do a quick finish on real marble
[12:03:01] <PetefromTn_> man ich I don't know what the hell you are trying to tell me heheh I mean I see your lips moving but all I hear is yada yada yada
[12:03:36] <PetefromTn_> is this something you are building?
[12:03:47] <PetefromTn_> and what kinda dragon we talking about here
[12:04:14] <IchGuckLive> yes
[12:05:12] <PetefromTn_> BBL
[12:05:36] <IchGuckLive> the 3d shader needs alot render effect so only a quick frame shot
[12:06:52] <IchGuckLive> http://foengarage.de/marble_1drag.jpg
[12:10:47] <IchGuckLive> PetefromTn_: is it that bad noone gots a return
[12:12:16] <Lathe_newbie> CaptHindsight: wanna build them mysel
[12:12:17] <Lathe_newbie> f
[12:13:00] <asah> looks like pete took off.
[12:13:09] <asah> are you building a dragon?
[12:13:25] <CaptHindsight> Lathe_newbie: I was just wondering what they were since it's a brand of belt and there is also an automation supplier by that name
[12:13:42] <IchGuckLive> not mee ist a foam art for a expo abaut 12-15 feet tall
[12:14:03] <asah> crazy
[12:14:10] <asah> carved foam?
[12:14:18] <IchGuckLive> milled
[12:14:20] <Lathe_newbie> CaptHindsight: just wanna take 2 ball bearings downside and the belt unter the bearings
[12:14:27] <Lathe_newbie> and on top the stepper
[12:14:58] <asah> fun!
[12:16:26] <asah> are you going to have a mill at your farmhouse?
[12:16:58] <IchGuckLive> no
[12:17:13] <IchGuckLive> no power there only 12V
[12:17:36] <asah> chisels and wood?
[12:17:38] <asah> =)
[12:18:00] <IchGuckLive> as you say i say outback ranger
[12:18:32] <asah> sounds pretty amazing. =)
[12:18:41] <IchGuckLive> we will see
[12:18:45] <asah> =)
[12:18:52] <IchGuckLive> been there now 2 days
[12:19:07] <asah> so you have internet?
[12:19:12] <IchGuckLive> no
[12:19:28] <IchGuckLive> only for discussing issues
[12:19:40] <asah> so you are not there now?
[12:19:51] <IchGuckLive> yes im at home
[12:20:01] <IchGuckLive> the old one
[12:20:27] <asah> ah. you will have to share some pics of the new place.
[12:22:19] <IchGuckLive> will do so
[12:22:24] <asah> this is pretty satisfying… I am ripping out all the wiring of the maho
[12:22:36] <asah> clean slate!
[12:22:55] <IchGuckLive> keep a good plan on that
[12:23:15] <asah> =) am going to regret some of it…
[12:23:32] <asah> but it swill be faster to run my own
[12:23:38] <IchGuckLive> but the 400 series is well documented
[12:23:41] <asah> I have the original schematics
[12:23:46] <IchGuckLive> ;-)
[12:23:55] <asah> but much of it is going away.
[12:24:09] <IchGuckLive> keep the good ones
[12:24:10] <asah> I have a 48 port input and 48 port output card.
[12:24:25] <asah> so I am going to do all the logic in linuxcnc
[12:24:53] <IchGuckLive> yea has it been equipt with the philips control
[12:24:59] <asah> got some solid state relays for the things that need high voltage
[12:25:32] <asah> there is lots of interlocks and safety logic being done in relays currently.
[12:25:48] <asah> Ill add a safety plc
[12:25:54] <asah> for the critical bits.
[12:26:11] <IchGuckLive> will you keep the axis breks
[12:26:23] <IchGuckLive> that may harm your speed
[12:26:40] <IchGuckLive> its still a manuel cnc as build
[12:26:41] <asah> axis brake?
[12:26:57] <asah> I don’t understand
[12:27:23] <IchGuckLive> the maho 400e got brekes on etch spiondle for movement they need to bee opend first
[12:27:47] <asah> right… mine had a z axis brake.
[12:27:55] <asah> (y axis originally)
[12:28:00] <asah> I have replaced the servos.
[12:28:07] <asah> new axes have brakes yes.
[12:28:22] <IchGuckLive> oh so total refit
[12:28:24] <asah> adding a new circuit for the brakes
[12:28:30] <asah> yes.
[12:28:43] <asah> hence the ripping out of the wires. =)
[12:29:46] <IchGuckLive> the x and y spindel is ok no black hole
[12:30:42] <IchGuckLive> hi Guest45444
[12:30:49] <IchGuckLive> alias cristian
[12:31:49] <IchGuckLive> asah: i woudt only keep the frame as you got all stuff new and go for new axis spindles also on that ballscrew costs
[12:32:05] <asah> https://www.dropbox.com/s/mgptg1nstb4j26k/maho_rewire.JPG
[12:32:14] <IchGuckLive> mae ot better then as factory out
[12:32:46] <asah> what about the ballscrew?
[12:33:19] <MrSunshine> asah, ough .. what a nightmare :P
[12:33:23] <asah> =)
[12:33:26] <IchGuckLive> maho fits in the standard bearings so it shoudt be easy to change
[12:33:36] <asah> ill up a pic when its nice and cleaned up.
[12:33:54] <IchGuckLive> looks as you overcome the main
[12:34:03] <archivist> luverly ratsnest
[12:35:34] <asah> =)
[12:35:41] <asah> at least I am not bored.
[12:37:26] <asah> IchGuckLive: so if I need to remake ballscrew then I am ok is what you are saying?
[12:37:29] <syyl_ws> looks not as messy as the maho700 of a friend of of mine :D
[12:37:32] <asah> reinstall.
[12:37:56] <syyl_ws> has the mh400 also a dc motor for the spindle?
[12:38:13] <Guest45444> servus ich guck live
[12:38:36] <IchGuckLive> asah: i looked at the drawings and the shaft pof SFU 2505 and 2510 fits
[12:39:43] <asah> syyl_ws: no, the spindle is AC induction motor
[12:39:46] <asah> 380V
[12:39:53] <syyl_ws> ah
[12:39:57] <syyl_ws> lucky man :D
[12:39:58] <IchGuckLive> i see also that now the 2504 is available on ali to get a mashine like that on a Stepper with perfect precission on direct drive
[12:40:11] <syyl_ws> the mh700 has an enormous dc motor
[12:40:33] <asah> what era mh700?
[12:40:42] <syyl_ws> good question
[12:40:46] <syyl_ws> its a mh700c
[12:41:08] <asah> they seemed to change all the systems in a bunch of eras.
[12:41:12] <asah> mine is 86
[12:41:16] <IchGuckLive> ah travalga there we go
[12:41:24] <asah> and has the 18 speed gearbox
[12:41:27] <travalga> mir gehts gut
[12:41:33] <travalga> und selber
[12:41:44] <IchGuckLive> only eng in the main please
[12:41:51] <IchGuckLive> hit my nick
[12:41:54] <syyl_ws> its 82
[12:41:59] <syyl_ws> just looked it up
[12:42:32] <asah> IchGuckLive: are you reccomending I replace the ballscrews with finer pitch?
[12:42:32] <syyl_ws> besides the dc motor a very nice machine
[12:42:48] <IchGuckLive> asah: up to you
[12:43:01] <IchGuckLive> you need to know what you want
[12:43:13] <asah> ah, these are 5mm and have a 4:1 stepdown from the motor
[12:43:15] <IchGuckLive> itas about 200USD and one saturday
[12:43:35] <syyl_ws> are the stock ballscrews shot?
[12:43:37] <asah> good to know,
[12:43:50] <asah> I am having backlash issues on the y axis.
[12:43:57] <asah> but I haven’t fully investigated it yet.
[12:44:19] <asah> once I get everything up and running Ill be able to tell.
[12:44:33] <IchGuckLive> syyl_ws: the maho got a open end so only a nut end "hülse is needed
[12:45:00] <syyl_ws> :D
[12:45:02] <syyl_ws> what? :D
[12:45:19] <asah> I think he is saying swapping the ballscrew is easy
[12:45:29] <IchGuckLive> shell
[12:45:46] <asah> because if you pull off the drive sprocket the ballscrew is easy access
[12:46:28] <asah> top left of that pic I upped
[12:46:33] <IchGuckLive> there is a distance cover shell so the standard fits
[12:46:36] <asah> is the end
[12:48:05] <IchGuckLive> asah: you will make it
[12:48:14] <IchGuckLive> first run on that
[12:48:28] <IchGuckLive> Scale is easy to change O.O
[12:48:32] <asah> =)
[12:48:43] <asah> I have been moving that axis under linuxcnc
[12:49:01] <asah> having issues with the glass scales readout, but feedforward is fine.
[12:49:09] <asah> off of the motor encoder.
[12:50:01] <IchGuckLive> woudent it be at first hand to stay at servo encoder
[12:50:18] <IchGuckLive> and then if later go back to glass
[12:51:35] <asah> yeah, I am not banging my heead too hard on the glass thing.
[12:51:48] <asah> getting it all up under motor encoders would be fine for a bit.
[12:52:05] <IchGuckLive> the servos shoudt be fine on your setup as here lots of people relie on that
[12:52:14] <IchGuckLive> ;-)
[12:52:36] <asah> well, I am not that far off.
[12:52:46] <asah> I have seen good quadrature out of the scales.
[12:52:53] <asah> and had it working.
[12:53:09] <asah> now I am working on getting differential out of the heidenhain exe platten.
[12:53:14] <asah> platine
[12:53:15] <asah> =)
[12:53:45] <asah> I could use your help to translate some of the mechanicals drawings I have. =)
[12:53:59] <asah> too bad you are going to be off in the woods.=)
[12:54:02] <IchGuckLive> michel is better
[12:54:05] <asah> you need to get a satellite modem
[12:54:07] <IchGuckLive> he is elektronics
[12:54:33] <asah> whats his nick?
[12:55:01] <IchGuckLive> loetmichel
[12:55:24] <asah> good to know. =)
[12:55:41] <IchGuckLive> he is always here and do this things
[12:59:04] <Loetmichel> i am here. whats the matter?
[12:59:21] <IchGuckLive> asah: got a heidenhein to retrofit
[12:59:28] <IchGuckLive> with german elek guide
[12:59:46] <Loetmichel> so?
[12:59:56] <Loetmichel> thas not that far from englisch anyways
[13:00:08] <Loetmichel> but if i can help i will
[13:00:33] <IchGuckLive> he mght ask you as i give him your profession
[13:00:36] <asah> cool, no problems today. just ripping out wiring. but I will be sure to ask for some translations at some point.
[13:02:00] <Loetmichel> <. is always here
[13:02:04] <jdh> where?
[13:02:22] <asah> great to meet you
[13:02:25] <Loetmichel> in this channel
[13:02:34] <Loetmichel> and if not:look for "cylly"
[13:03:01] <Loetmichel> and it that nick isnt here either: call the cops, i have been abducted ;-)
[13:03:16] <IchGuckLive> or firerd
[13:03:22] <Loetmichel> hmm`?
[13:03:27] <Loetmichel> why?
[13:03:32] <IchGuckLive> on to many smoke pauses
[13:03:43] <Loetmichel> i dont smoke anymore
[13:03:56] <Loetmichel> and the e-cig i can use in the office
[13:04:10] <Loetmichel> but THIS pc wehre the irc client is on is at home
[13:04:29] <Loetmichel> even when i type from work i do that per VNC to this PC
[13:05:14] <Loetmichel> ... because IRC isnt allowed at the company... VNC home is, so i can use my private CNC soft for the company ;-)
[13:09:03] <IchGuckLive> hi dieter_
[13:09:19] <dieter_> Hello, Good evening somebody out there interested to give me some advice how to set up HB04 Handwheel?
[13:11:07] <IchGuckLive> did you see the wiki on that
[13:11:24] <jthornton> got a link to one?
[13:11:27] <IchGuckLive> in the 2.6.2 there is a hb04 comp
[13:11:38] <archivist> note wifeless http://www.ebay.co.uk/itm/2-4G-Wireless-Handwheel-Electronic-Mach3-MPG-Pendant-for-CNC-Mac-Mach-3-4-Axis-/131239063971?pt=UK_BOI_Industrial_Automation_Control_ET&hash=item1e8e7531a3
[13:11:58] <dieter_> yes, but my install is complaining about various missing things
[13:12:04] <IchGuckLive> dieter_: are you german
[13:12:20] <dieter_> ja deutsch :-)
[13:12:32] <IchGuckLive> ich sitz in kaiserslautern
[13:12:42] <dieter_> its the usb version
[13:13:03] <dieter_> oh lust vorbeizukommen ich bin bei zweibrücken#
[13:13:41] <IchGuckLive> leider nicht ich bin im startrek team der FH
[13:13:44] <dieter_> almost the one in the link just with wire
[13:14:08] <dieter_> was macht man da?
[13:14:10] <IchGuckLive> so if you got the USB one just hook it up it tels you the pins
[13:14:21] <archivist> I imagine the pc sees the same regardless
[13:14:59] <IchGuckLive> dieter_: hit my nick
[13:15:30] <dieter_> pc finds it i followed the instructions on linuxcnc wiki but i am no programmer
[13:19:00] <asah> deiter_ what are your issues?
[13:19:02] <archivist> ask more specific questions where you are stuck
[13:26:24] <MrSunshine> anyone know where one can find "recommended" speeds and feeds for cmt tools?! :/
[13:26:31] <MrSunshine> shouldnt there be some document about that?
[13:26:41] <archivist> the seller of the tools
[13:29:16] <archivist> often with speeds and feeds well above the older machines abilities
[13:30:48] <jdh> how about speed/feed for 0.078" 3 flute carbide cutter slotting 316SS?
[13:43:47] <PetefromTn_> http://i.imgur.com/X1cHkRh.jpg Pretty maids all in a row LOL
[13:44:11] <asah> nice pete
[13:44:11] <zeeshan> sexyyy
[13:44:12] <zeeshan> !
[13:44:26] <zeeshan> PetefromTn_: are you using and end mill
[13:44:27] <zeeshan> to make that slot
[13:44:29] <PetefromTn_> yeah best part is they are all sold already...
[13:44:35] <onyedikilo> hi
[13:44:39] <PetefromTn_> which slot?
[13:44:43] <zeeshan> the really long one
[13:44:46] <zeeshan> between the symmetrical faces
[13:45:07] <PetefromTn_> if you mean the long slot down the bottom that is made with a 3/8 inch ball endmill
[13:45:55] <PetefromTn_> I got a couple more orders for them here now so I gotta make another small batch of them. These are the ones that are ready for hardware and packaging.
[13:46:13] <onyedikilo> i have a problem with my x axis movement, i was to check for backlash and used a dial indicator. If i move the axis 1mm's it moves 0.8 - 1.4 mm's. If i move the axis 5 mm's it goes 5mm's. Any ideas? dual direct drive x axis.
[13:46:35] <zeeshan> very cool
[13:46:36] <zeeshan> :D
[13:47:01] <jdh> pretty nice. chamfering all done on the machine?
[13:47:02] <onyedikilo> any ideas?
[13:47:15] <PetefromTn_> Now I am going to setup and machine the first prototype of the rail for another rifle which is quite different from these.
[13:47:43] <PetefromTn_> yeah all the champfering except for the deburring I have to do on the internal side of those large pockets is done on the mill on both sides.
[13:48:42] <jdh> it just clamps on? no intenal slot on the inside?
[13:49:10] <PetefromTn_> onyedikilo sounds like you might have some stiction or something or you are experincing some initial movement that is taken out with enough travel.
[13:49:22] <archivist> onyedikilo, backlash shows up on reversals, if you keep moving one direction after taking up lost motion you wont see any more error
[13:50:03] <PetefromTn_> the part clamps on with dovetails onto the rifles dovetail rails and the screws tighten it down while the whole assembly flexes just slightly to account for that. It is the way quite a few rails like this work.
[13:50:48] <jdh> that's what I meant... I just can't see a dovetail in yoru part
[13:50:54] <PetefromTn_> it might be hard to see the dovetail grooves in the picture. They are just .095 deep and about half that wide into the side rails.
[13:51:35] <IchGuckLive> onyedikilo: what is your scale
[13:52:09] <onyedikilo> IchGuckLive, dial indicator has 0.01mm precision
[13:52:30] <PetefromTn_> they clamp onto a shallow small dovetail on the rifles barrel shroud which is cut into a relatively thin walled tube so you cannot have a deep groove there or actually you can but it is not necessary. These clamp on very strong and since it is just a 12ftlbs air rifle it does not take much since there is virtually ZERO recoil.
[13:52:36] <onyedikilo> IchGuckLive, is that what you meant ?
[13:53:15] <IchGuckLive> no in the ini you got a scale value on etch axis what does SCALE show on Acis_0
[13:53:38] <archivist> scale is not the problem
[13:53:41] <PetefromTn_> https://www.google.com/search?q=FWB+P70+custom+rails&client=firefox-a&hs=Ft8&rls=org.mozilla:en-US:official&channel=fflb&source=lnms&tbm=isch&sa=X&ei=OEfyU8zaLMi-sQTLs4LYDQ&ved=0CAkQ_AUoAg&biw=1706&bih=841&dpr=0.8#facrc=_&imgdii=_&imgrc=oqI5uYFzsJer_M%253A%3BtOsABO5l0PuLcM%3Bhttp%253A%252F%252Fi1104.photobucket.com%252Falbums%252Fh323%252Fmgkd1%252F100_1989_zps7e0ed996.jpg%3Bhttp%253A%252F%252Fwww.network54.com%252FForum%252F
[13:53:50] <PetefromTn_> oops sorry for the large link.
[13:54:11] <PetefromTn_> http://i1104.photobucket.com/albums/h323/mgkd1/100_1989_zps7e0ed996.jpg
[13:54:15] <jdh> oh, those are a lot bigger than I was thinking.
[13:54:15] <PetefromTn_> thats better LOL
[13:54:40] <jdh> you need to anodize them.
[13:55:04] <PetefromTn_> yeah I designed them to fit the rifle and clear the arc'd vertical swing of the loading port.
[13:55:24] <PetefromTn_> yup sure do LOL.... trying to get enough cash together to get an anodization station setup.
[13:55:34] <PetefromTn_> They would look sweet in black or blue I think.
[13:55:41] <onyedikilo> do i need to fix it? what do you think?
[13:56:01] <jdh> is it real, or your measurement technique
[13:56:18] <CaptHindsight> PetefromTn_: is that the largest part that you'd need to anodize?
[13:56:19] <jdh> Pete: gold, red, blue, black
[13:56:42] <jdh> $100 for stuff to anodize thousands of them
[13:56:45] <PetefromTn_> sure whatever color they want just need to get it done and I have never done it before.
[13:56:57] <PetefromTn_> LOL I WISH I could sell thousands of these.
[13:57:13] <PetefromTn_> I actually make a nice profit on them but I am not getting the numbers I was hoping for.
[13:57:30] <jdh> make some Ti ones
[13:57:41] <PetefromTn_> The new rail I am going to make tomorrow should be really cool. I hope between the two I can make some nice cash.
[13:57:46] <PetefromTn_> naah it is not worth it.
[13:58:01] <PetefromTn_> these are pretty light and serve the purpose without being too over the top.
[13:58:03] <jdh> but some decorative rubber things in the middle and call them harmonic stabilizers for greater accuracy
[13:58:04] <archivist> onyedikilo, you can write your gcode so it all works in one direction (like a manual machine would be used)
[13:58:05] <onyedikilo> archivist, if i keep moving in one direction in 1mm increments, it never goes 1mm. changes from 0.8 to 1.4 mm
[13:58:09] <PetefromTn_> I think that is why I have sold quite a few now.
[13:58:24] <PetefromTn_> LOL not a bad idea
[13:58:41] <onyedikilo> archivist: lol
[13:58:42] <archivist> onyedikilo, what stepper to leadscrew ratio
[13:59:01] <PetefromTn_> BRB gotta go pickup my kids.
[13:59:11] <onyedikilo> archivist : stepper 1600 steps per rev, 10mm leadscrew pitch
[13:59:39] <archivist> is that microsteps?
[13:59:49] <onyedikilo> archivist : 8 microsteps
[14:00:02] <onyedikilo> archivist : 8 x 200
[14:00:21] <onyedikilo> archivist : 160 microsteps per 1mm travel
[14:00:32] <archivist> well 200 is the real number of accurate positions
[14:01:02] <archivist> the microsteps in between will not be as accurate
[14:01:38] <onyedikilo> archivist : y and z axis are running fine
[14:01:53] <SpeedEvil> To do it properly, you need to calibrate microsteps
[14:02:04] <SpeedEvil> but that's not very commonly possible in most drivers
[14:02:10] <onyedikilo> archivist : but i will keep that in mind and experiment changing the steps
[14:02:12] <archivist> you can verify by carefully noting all steps over a distance http://www.archivist.info/cnc/screw_error/
[14:02:36] <SpeedEvil> Microstepping assumes generally that the motors follow nice sinewave patterns - in reality there is distortion
[14:02:49] <archivist> large distortion
[14:03:02] <onyedikilo> ok i will change it to 10 microsteps then
[14:03:13] <SpeedEvil> number of microsteps isn't really the issue
[14:03:30] <onyedikilo> to make it more accurate for the sake of the machine
[14:03:40] <archivist> the assumption of accuracy of microsteps is the problem
[14:03:45] <pcw_home> you have errors > full steps so probabl mechnical
[14:04:02] <onyedikilo> i use the microsteps for compensating the vibrations
[14:04:43] <archivist> yes that is the best reason to use them, does the leadscrew feel lumpy
[14:04:59] <archivist> bad bearing
[14:05:59] <onyedikilo> leadscrews sound growling, bad alignment of motors, i will reposition them
[14:06:03] <pcw_home> with 10mm pitch your -0.2 +0.6 mm errors are 4 and 12 full steps respectively (so not ustep related at all)
[14:07:43] <pcw_home> so really sounds mechanical: leadscrew shift in bearings, bad coupling to step motor, backlash etc
[14:08:43] <onyedikilo> couplers have a slight angle and make the leadscrews whip, i need to reposition the motors asap
[14:10:05] <CaptHindsight> onyedikilo: what type of coupler are they?
[14:10:22] <CaptHindsight> have a pic?
[14:10:36] <onyedikilo> aluminum servo couplers, let me find one on the web
[14:11:10] <onyedikilo> http://i01.i.aliimg.com/wsphoto/v0/1896264925/5x6-6mm-aluminium-flexible-shaft-Jaw-spider-Plum-font-b-Coupling-b-font-servo-motor-rolling.jpg
[14:11:57] <onyedikilo> CaptHindsight : looks exactly like the one in the picture
[14:12:03] <CaptHindsight> those will act like springs
[14:12:12] <archivist> motor axis needs to be reasonably inline with that type
[14:12:39] <onyedikilo> i see, motor misalignment could be the issue then ?
[14:12:47] <onyedikilo> with those couplers
[14:13:23] <CaptHindsight> and they polymer section will compress and expand like a spring
[14:14:11] <onyedikilo> any suggestions for a coupler which will help with the misalignment? or do you suggest a better alignment for the motors?
[14:15:34] <CaptHindsight> https://sdp-si.com/ss/gif/78506054D.jpg oldham types will slide to make up for missaligment
[14:16:04] <CaptHindsight> the type you have will compress and expand creating play
[14:16:22] <onyedikilo> i see thank you
[14:16:58] <CaptHindsight> it's always best to have the motor and screw shafts aligned as much as possible
[14:17:14] <onyedikilo> i will remachine them tomorrow
[14:20:42] <CaptHindsight> https://sdp-si.com/ss/gif/SSBCI9.JPG bellows is another type that will handle some missalignment with flex without losing precision
[14:21:25] <CaptHindsight> onyedikilo: it depends on how the shafts are out of alignment and by how much
[14:25:42] <onyedikilo> how much misalignment is reasonable?
[14:30:28] <JEntrep> Is anyone here familiar with sewing automation?
[14:31:14] <MrHindsight> onyedikilo, http://www.ludeca.com/brochures/Ludeca_A-Practical-Guide-to-Shaft-Alignment.pdf
[14:31:30] <JEntrep> MrHindsight, is that for me?
[14:31:32] <onyedikilo> thanks
[14:31:45] <JEntrep> oh nm
[14:35:02] <MrHindsight> onyedikilo http://machinedesign.com/mechanical-drives/10-tips-using-couplings-your-application
[14:35:59] <MrHindsight> onyedikilo, http://machinedesign.com/archive/prevent-coupling-failure-good-design-installation-and-maintenance
[14:36:42] <onyedikilo> MrHindsight, thank you
[14:39:07] <MrHindsight> JEntrep, just ask the question, some here are ME's, machinists and automation engineers with decades of experience
[14:41:09] <MrHindsight> onyedikilo, and one more http://www.ruland.com/pdf/Servo%20Couplings%20Article_web.pdf
[14:44:18] <JEntrep> MrHindsight, Like if two pieces of material are cut via some CNC machine
[14:44:24] <JEntrep> what are some methods for bringing them to a single sewing point in an automated process?
[14:47:41] <zeeshan> damn i love being in research
[14:47:48] <zeeshan> i just downloaded 1000$ worth of astm standards
[14:47:49] <zeeshan> lol
[14:47:52] <zeeshan> for FREE!!!
[14:48:04] <JEntrep> torrent? ;P
[14:48:12] <zeeshan> i couldnt find em on torrent
[14:48:14] <MrHindsight> zeeshan, university subscription?
[14:48:30] <zeeshan> so i asked the research group if we have access to standards and they looked at me funny and said "ofcourse we do"
[14:48:46] <zeeshan> MrHindsight: yes
[14:48:53] <zeeshan> so if anyone needs anything
[14:48:55] <zeeshan> do let me know
[14:49:04] <MrHindsight> JEntrep, depends on how they need to meet, shape and size of the pieces
[14:49:14] <Jymmm> zeeshan: Do you have ASTM D-4236 you could "share"?
[14:49:22] <JEntrep> MrHindsight, specifically for Shoes
[14:49:36] <zeeshan> Standard Practice for Labeling Art Materials for Chronic Health Hazards
[14:49:37] <zeeshan> ?
[14:49:59] <Jymmm> zeeshan: "non toxic" labeling for kids shit
[14:50:18] <MrHindsight> knitting needles in the eyes and so forth?
[14:51:44] <Jymmm> zeeshan: I came across a item marked "non toxic" but when I opened the cap if had ammonia in it. So, I've always been curious what the ASTM states =)
[14:51:55] <zeeshan> Jymmm: http://www.docdroid.net/gbe5/d4236000132596-1.pdf.html
[14:52:00] <zeeshan> uploaded it
[14:52:21] <zeeshan> looks like a dry topic :P
[14:52:43] <zeeshan> i cant believe they want 42$ for that document
[14:52:43] <Jymmm> zeeshan: TY, <rimshot>
[14:52:48] <zeeshan> of dry stuff
[14:53:01] <zeeshan> np
[14:53:07] <Jymmm> zeeshan: Yeah, ths why I never persued it before
[14:53:17] <Jymmm> pursued* ?
[14:53:36] <Jymmm> It was "glass paint" fyi
[14:53:47] <MrHindsight> "There are presently no specific national standards for labeling art
[14:53:47] <MrHindsight> materials with respect to chronic health hazards."
[14:54:16] <Jymmm> MrHindsight: Go tell Crayola Crayons that =)
[14:54:27] <MrHindsight> Uranium Color Sticks are not for use with children under 3
[14:55:00] <Jymmm> MrHindsight: But Cesium-137 discs are =)
[14:56:14] <Jymmm> MrHindsight: http://unitednuclear.com/index.php?main_page=product_info&cPath=2_5&products_id=819&zenid=17c4046b2083b7215de8f14d73e6cbc1
[14:56:31] <MrHindsight> JEntrep, http://www.youtube.com/watch?v=bbaSp8l9vt0
[14:57:19] <MrHindsight> a pick-n-place could handle those parts
[14:58:50] <JEntrep> MrHindsight, pick and place, true :)
[14:59:07] <JEntrep> MrHindsight, do you have any information on pick-and-place vendors and pricings?
[15:00:18] <MrHindsight> JEntrep, general purpose SCARA robots, search for SCARA and also end of arm vacuum tooling
[15:02:27] <MrHindsight> also machine vision, there's probably not a specific system for shoe soles, you'd just integrate the parts for the process
[15:02:58] <JEntrep> MrHindsight, have any vendor examples for that?
[15:05:44] <MrHindsight> JEntrep, or a delta bot http://www.youtube.com/watch?v=wg8YYuLLoM0
[15:08:48] <MrHindsight> http://www.youtube.com/watch?v=pMB5PZgPsnk Multi-robot sewing of recliner covers
[15:09:52] <MrHindsight> http://www.youtube.com/watch?v=8i6TYxrW_qc SCARA sewing
[15:12:10] <MrHindsight> JEntrep, I'd estimate $100K and up for a good system
[15:13:13] <MrHindsight> depending on how it gets fed materials and how it has to sew them and stack them
[15:14:45] <JEntrep> MrHindsight, Thanks for the rough estimate
[15:15:01] <JEntrep> It lets me know the ballpark figure will likely be a low 6 figures :)
[15:16:16] <MrHindsight> turn key, programmed with all the accessories
[15:17:05] <JEntrep> MrHindsight, hmmm, turn key componets, but not the whole system.
[15:17:06] <JEntrep> :/
[15:17:13] <MrHindsight> small SCARAS start around $10K new
[15:17:32] <MrHindsight> JEntrep, depends on what the "whole" system is
[15:19:04] <MrHindsight> does it start with a few stacks of sole parts and places the completed sole on a belt when complete or where does it start and end?
[15:22:46] <JEntrep> MrHindsight, nope, individual specifications, custom cut CNC soles, can be move via conveyor belt, or pick-and-place.
[15:22:59] <JEntrep> *(CNC)
[15:23:21] <JEntrep> needs to be sewn to insole, and upper componets
[15:23:34] <JEntrep> insole is CNC cut
[15:23:42] <JEntrep> upper componets can be CNC cut as well
[15:23:51] <JEntrep> the assembling/sewing part is the tough point
[15:24:23] <JEntrep> may be easiest to just have a working hand
[15:24:28] <MrHindsight> what materials? mostly leather or synthetics?
[15:25:14] <JEntrep> leather, sude, cotton blends, etc.
[15:25:27] <JEntrep> *suede
[15:25:34] <JEntrep> and yes synthetics as well.
[15:25:58] <MrHindsight> natural materials on the uppers is usually done by hand
[15:26:39] <MrHindsight> but for synthetics you can 3d print, but I don't expect it to happen in the USA
[15:26:51] <MrHindsight> not in high volume
[15:27:00] <JEntrep> 3D printing in the USA, not happening?
[15:27:18] <JEntrep> or high volume assembly in general, you mean?
[15:27:33] <JEntrep> not necessarily looking for high volume at first
[15:27:51] <MrHindsight> high volume applications of anything under patent by 3d systems or similar
[15:27:55] <JEntrep> the sole/insole *could* be 3D printed
[15:28:18] <JEntrep> MrHindsight, ah, you are saying it could be a legal problem to print designs
[15:28:23] <jdh> if you wanted pricey brittle insoles
[15:28:45] <JEntrep> jdh, just read an article about using NinjaFlex for insoles
[15:28:52] <JEntrep> apparently it is supposed to be comfortable
[15:29:08] <JEntrep> but I will look into it more
[15:29:16] <MrHindsight> 3d systems and similar don't care about high volume low margin applications, they control the patents and only target low volume high margin applications
[15:29:23] <MrHindsight> please prove me wrong
[15:29:34] <jdh> You are *WRONG*, it says so in teh bible.
[15:29:59] <MrHindsight> jebesus
[15:30:31] <JEntrep> hmmm, well how hard is it to scale 3D printing?
[15:30:41] <JEntrep> I actually plan on starting at low-volume, low-margin
[15:30:47] <JEntrep> er ... *decent-margin
[15:30:50] <MrHindsight> it's not, just expensive in the west
[15:30:59] <JEntrep> I figured it wasn't
[15:31:04] <JEntrep> just need a good Asian vendor
[15:31:16] <JEntrep> and batch purchase machine
[15:31:18] <JEntrep> *machines
[15:35:29] <MrHindsight> http://www.ecouterre.com/myth-is-the-worlds-first-3d-printed-ready-to-wear-shoe-collection/
[15:36:56] <JEntrep> MrHindsight, the upper design being done by hand is what I am trying to avoid :/
[15:37:16] <MrHindsight> http://www.knittingindustry.com/nike-combines-3d-knitting-with-3d-printing-in-new-sports-footwear-range/
[15:38:13] <MrHindsight> yeah, it can all be 3d printed but it requires hybrid printers with patents held by various non-cooperating entities
[15:38:54] <MrHindsight> inkjet + fdm could do that
[15:39:35] <MrHindsight> or sls + inkjet
[15:39:55] <JEntrep> fdm?
[15:39:56] <JEntrep> sls?
[15:40:19] <MrHindsight> http://en.wikipedia.org/wiki/Fused_deposition_modeling
[15:40:56] <MrHindsight> http://en.wikipedia.org/wiki/Selective_laser_sintering
[15:42:00] <JEntrep> hybrid printers?
[15:42:18] <JEntrep> why not two printers in succession on a line? ;)
[15:43:34] <MrHindsight> if the parts work out that way, but then you have parts moving back and forth between printers
[15:44:52] <CaptHindsight> something like crocs could be done in one process
[15:45:19] <JEntrep> CaptHindsight, :p
[15:48:31] <CaptHindsight> reminds me of Idiocracy :)
[15:48:48] <CaptHindsight> and the clothing without buttons or snaps
[15:50:37] <CaptHindsight> http://www.shoebuy.com/pi/crocs/jb/crocs558435_319707_jb.jpg something like this could be done with SLA/DLP
[15:53:06] <SpeedEvil> There are real problems with printing some shoes, especially dutch ones.
[15:53:12] <SpeedEvil> They clog the printer.
[15:53:22] <CaptHindsight> <rimshot>
[16:27:03] <Deejay> gn8
[16:28:25] <JT-Shop> must be time for a beer if Deejay went to bed
[17:57:10] <zeeshan> grr
[17:57:16] <zeeshan> there is no post for mastercam for linuxcnc lathe
[18:20:07] <CaptHindsight> Linuxcnc is now working with 3.10 RTAI 64b kernels!
[18:21:50] <PCW> Thats really great
[18:23:33] <CaptHindsight> PCW: did you need v2.12+ for the new Intel Celeron boards?
[18:24:18] <PCW> yeah 3.12+
[19:29:08] <PCW> Ha! the BISS interface runs at 100 MHz, too bad there's no similar SPI standard (data driven timing)
[19:30:48] <asah> I want BISS
[19:30:53] <asah> on everything.
[19:31:25] <CaptHindsight> http://en.wikipedia.org/wiki/BiSS_interface dis biss?
[19:31:41] <PCW> yes
[19:31:51] <asah> none of this differential quadrature nonsense
[19:32:07] <asah> =)
[19:32:40] <PCW> well its still differential...
[19:33:35] <asah> =) new problems. surely… but probably less noise problems.
[19:33:43] <asah> still cant’ get the scales output properly sorted.
[19:34:06] <asah> not working on it today, but last session left me trying to figure out which were the correct differential lines.
[19:34:07] <PCW> normally differential quadrature is pretty noise immune
[19:34:34] <asah> did you get a chance to look at that oscilliscope screenshot I sent you last week?
[19:34:35] <PCW> (same signaling as BISS)
[19:34:42] <asah> that was ttl, looked pretty noise free.
[19:35:03] <asah> but still had issues.
[19:35:21] <PCW> do you have another EXE box?
[19:35:29] <asah> no.
[19:35:34] <asah> just three channels on that one.
[19:35:44] <asah> it has successfully worked in the past.
[19:37:29] <PCW> possibly scale issues as well (can you try a normal encoder?)
[19:38:31] <asah> sure.
[19:39:39] <PCW> It could be a bad input but normally these would show up as visibly bad data
[19:40:23] <asah> the exe board uses this driver: http://www.ti.com/lit/ds/symlink/mc3487.pdf
[19:40:40] <asah> it breaks out all the leads from that driver chip
[19:41:04] <asah> but then only runs one side of the leads out to the original control.
[19:41:15] <asah> there is only a single A line for instance.
[19:41:32] <asah> and the other lines are not attached.
[19:41:44] <PCW> TTl signals are pretty noise sensitive
[19:42:19] <PCW> did you try lowering the encoder sample rate to increase the filtering?
[19:42:34] <asah> it appears to me that I should just be able to attache to the other side of the pin
[19:42:40] <asah> driver chip rather.
[19:42:57] <asah> and get real differential
[19:43:03] <PCW> BTW the 8I20 issue was firmware
[19:43:26] <asah> oh great.
[19:43:35] <asah> no, I haven’t tried to reduce sample rate.
[19:43:48] <asah> I ran into an issue with writing the parameter.
[19:44:02] <asah> and that would affect all encoders yes?
[19:44:05] <PCW> must have been at the transition where we make the drive capable of restarting if enable was restored
[19:44:45] <PCW> yes its global, but you can enable of disable the extra filtering on a encoder by encoder basis
[19:44:57] <PCW> enable or disable
[19:45:06] <asah> ah, ok.
[19:45:19] <asah> so that will help if I have noise issues.
[19:45:48] <asah> I didn’t see individual encoder filter enables. unless that is the filter 1, vs 0 thing
[19:46:08] <asah> what do you think about my differential theory.
[19:46:11] <asah> am I crazy?
[19:46:22] <asah> trying to get that other leg of differential going?
[20:06:04] <PCW> The filter bit sets the encoder input filter to 3 (0) or 15 (1) clocks
[20:06:26] <PCW> I would try setting the sample rate down first
[20:10:03] <jdh> `
[20:10:25] <asah> ok… Ill try that next time Im hacking on the scales.
[20:10:36] <asah> am currently ripping out old wiring.
[20:12:23] <PCW> dont rip out any good stuff....
[20:12:43] <asah> eh.. rip out means recycle.
[20:12:47] <asah> its all going back in...
[20:12:49] <asah> =)
[20:13:01] <asah> not cutting anything, its all terminal blocks.
[20:13:06] <asah> very neat.
[20:13:20] <asah> and I have the original schematics.
[20:13:32] <asah> a bunch of it was three phase that is not applicable anymore.
[20:13:32] <PCW> That helps
[20:14:11] <asah> replacing a bunch of the relay logic with ins and outs on the 7i70 and 7i71
[20:14:41] <asah> Ill have a bunch more tranparency as to what is tripping out, as opposed to these long interlock legs right now.
[20:14:55] <PCW> Yeah replacing relay logic is a win
[20:15:35] <asah> got a lot of solid state relays for cheap on ebay.
[20:15:59] <asah> still not sure about the main power contactor for the spindle power, as that is going to be 380 still.
[20:16:04] <asah> as will the hydraulix.
[20:16:23] <asah> I will likely reuse some of the current contactors.
[20:16:34] <asah> or find some solid state ones.
[20:16:58] <asah> although I do like that “thunk”when contactors go off. you know you are powered up and should be scared. =)
[20:17:24] <PCW> Not as easy to find big SSRs for large motors
[20:17:43] <asah> I figured.
[20:17:46] <asah> prob not cheap.
[20:17:49] <asah> haven’t looked yet.
[20:19:27] <PCW> If the contactors are OK I would just leave them (you will need SSRs to drive them)
[20:21:53] <asah> Ill certainly start there. these will be the power feeds for the vfds.
[20:22:10] <asah> one vfd each for Spindle, Hydro
[20:22:19] <asah> which need 380V 3 phase.
[20:22:39] <asah> I understand its a bad idea to switch after the VFD.
[20:22:53] <asah> so Ill not do that.
[20:24:49] <PCW> Some systems do that but they are designed for it (switching the (BLDC) motor leads between drive and braking load)
[20:25:31] <PCW> I dont think VFDs are designed for that
[20:25:43] <asah> I remember somewhere not.
[20:26:41] <asah> I wonder if in an estop situation I would trust the VFD to spin down the spindle (brake it) or I should kill contactor. anyone doing this?
[20:27:23] <PCW> I think Estop must kill the primary power
[20:29:24] <asah> there are situations in industrial robotics where i have seen the safety system do a controlled ramp stop as being the safe way to go.
[20:29:42] <asah> but it would certainly be dependant on the system.
[20:30:07] <asah> Not sure how quickly the spindle would shut down under each circumstance.
[20:30:19] <asah> certanily more reliable to kill power.
[20:30:33] <asah> reliable is good in estop situations. =)
[20:30:34] <PCW> yeah, with BLDC its easier since you dont need power to brake
[20:31:25] <PetefromTn_> evening folks
[20:31:27] <PCW> A load on the (unpowered) DC bus side will slow everything down
[20:31:42] <CaptHindsight> I just had issues with a stepper and e-stop generating back EMF
[20:31:55] <asah> shunt resistor, and I am good not having that installed on the 8i20 ? a
[20:32:21] <asah> as long as my power supply has it (which it does) and I am not switching in between 8i20 and power supply.
[20:32:27] <asah> correct?
[20:32:47] <PCW> Yes
[20:33:33] <PCW> though a shunt resistor across the bus when DC power is off will give braking when all electronics is off
[20:34:52] <PCW> (the IGBT modules act as 3 phase rectifiers powering the DC bus even when all electronics is disabled)
[20:35:52] <PCW> CaptHindsight: may want a snubber across the power supply (or a bigger output capacitor)
[20:53:04] <asah> PCW: will the filtering effect the quadrature rate or just the phase delay? I suppose just the phase delay (small at 8mhz) =)
[20:53:36] <asah> it caps the speed at which you can run the axis I bet.
[20:53:49] <asah> otherwise you saturate the quadrature reads.
[20:53:55] <asah> right?
[21:24:59] <CaptHindsight> PCW: nah, instead of parking the Z before turning it off, they were hitting e-stop while under load, it was probably reaching 600rpm for the 2 seconds it dropped
[21:27:26] <pcw_home> filtering will effect the maximum count rate so if you set the sample rate too low you will start to lose counts at high speed
[21:42:21] <anarchos2> i just made my first chips ever :)
[21:42:33] <XXCoder> via cnc? ;)
[21:42:36] <anarchos2> wood chips, but exciting none the less
[21:42:38] <anarchos2> yea
[21:42:47] <anarchos2> my end mill set just showed up this morning
[21:43:03] <XXCoder> LOL okay. was thinking kind you eat. was joking about cnc that makes chips
[21:43:26] <anarchos2> i ran the "LinuxCNC" sample gcode with a 1/8" end mill, so it kinda looks crappy
[21:43:35] <anarchos2> but worked flawlessly on the cnc side of things
[21:43:39] <Jymmm> Mmmmm nachos
[21:43:49] <anarchos2> now i need to find a vise.
[21:43:51] <Jymmm> Carne Asada Nachos
[21:43:53] <anarchos2> i can't decide
[21:44:29] <Jymmm> anarchos2: Random sex with strangers?
[21:44:43] <Jymmm> Binge drinking?
[21:44:46] <anarchos2> lol
[21:45:02] <anarchos2> "spending too much money on hobbies" is my real vise.
[21:45:07] <anarchos2> http://www.amazon.ca/Grizzly-G5976-Improved-Drill-4-Inch/dp/B0000DD4UF/ref=sr_1_11?ie=UTF8&qid=1408415119&sr=8-11&keywords=grizzly+vise
[21:45:18] <anarchos2> think that would be useless for a mini mill/aluminum?
[21:45:27] <anarchos2> can't really afford a real vise at the moment
[21:45:48] <Jymmm> anarchos2: you a canuck?
[21:45:52] <anarchos2> yea
[21:46:01] <Jymmm> what about Canadian Tire?
[21:47:16] <anarchos2> i live in "the middle of nowhere" (tool availability wise), Canadian tire is 45 minute drive
[21:47:22] <anarchos2> easier to order from amazon :P
[21:47:25] <Jymmm> ah
[21:47:46] <Jymmm> It's the only canuck store I'm aware of
[21:47:54] <Jymmm> for tools
[21:48:03] <Jymmm> thought the name is misleading
[21:48:36] <anarchos2> i think at one point in time back in they day they only sold tires/auto tools :P
[21:48:57] <anarchos2> now it's like a...wal-mart but with a bigger selection of tools and tires than wal-mart :P
[21:49:07] <Jymmm> Yeah, I figured =)
[21:49:47] <anarchos2> i want one of these, but $110+$80 shipping+UPS brokerage fees+Duty+tax = ~CAD$300 probably
[21:50:00] <anarchos2> http://www.ebay.ca/itm/4-ANG-LOCK-CNC-VISE-FOR-CNC-BRIDGEPORT-MILLING-MACHINE-NEW-/181062805168?pt=BI_Tool_Work_Holding&hash=item2a282f26b0&_uhb=1
[21:50:50] <Jymmm> $75 shiping?! they on rack???
[21:50:57] <XXCoder> kurt seems king of vise
[21:50:57] <Jymmm> Crack
[21:51:08] <XXCoder> its HEAVY item
[21:51:14] <Jymmm> So?
[21:51:19] <anarchos2> seems about standard for something that weight to go from US->Can
[21:51:22] <XXCoder> shipping dont like heavy stuff
[21:51:24] <XXCoder> indeed
[21:51:28] <Jymmm> USPS Priority mail 75lb flat rate for $12
[21:51:31] <XXCoder> I ship to canada often
[21:51:36] <ChuangTzu_> lol
[21:51:42] <XXCoder> and man prices flies fast with weight
[21:51:44] <Jymmm> err 70 lb
[21:51:51] <ChuangTzu_> try fitting 70lbs into a flat rate box
[21:51:58] <XXCoder> dont think that fits in box...
[21:51:58] <ChuangTzu_> unless you're using gold bars
[21:52:23] <XXCoder> ChuangTzu_: or reforced lead, whatever that is. I once handled 2 SMALL priority boxes that was very close to limit.
[21:52:24] <anarchos2> I had my harbor freight mill shipped to the border in Washington state for $12. They quoted me $398 to ship to my door (the mill cost $412 after discounts!)
[21:52:33] <XXCoder> almost dropped em into my foot. would have broke it
[21:53:08] <ChuangTzu_> anarchos2: did you know someone or did you ship it general delivery?
[21:53:30] <anarchos2> ChuangTzu_, there are businesses on the border that cater to Canadians
[21:53:53] <ChuangTzu_> ah, of course there are
[21:53:55] <anarchos2> you sign up online, and they provide you with a "suite #" that you have stuff shipped to
[21:54:02] <ChuangTzu_> makes sense
[21:54:08] <anarchos2> crazy thing is, it cost me $4.
[21:54:34] <anarchos2> someone had to unload a 140lbs crate, bring it inside, they stored it for 5 days, then helped me load it into my car. for $4.
[21:54:45] <anarchos2> so cheap :)
[21:54:48] <XXCoder> yeah
[21:55:03] <XXCoder> land there must be so cheap for them to afford employees AND land tax
[21:55:35] <Jymmm> anarchos2: http://www.amazon.com/InstaMorph-Moldable-Plastic-12-oz/dp/B003QKLJKQ
[21:55:50] <anarchos2> yeah, it's kinda funny, on the Canadian side it's very built up, lots of really big houses that cost a fortune (as most houses do in Canada)
[21:56:10] <anarchos2> and the US side is kinda run down, there's a bunch of big box stores that cater to Canadians, and not much else :P
[21:56:27] <Jymmm> Even better http://www.amazon.com/Thermomorph-Moldable-Plastic-Pellets-Amazon/dp/B00D3LAZ9O/ref=pd_tcs_subst_ac_1?ie=UTF8&refRID=06Y9H0PY9097VYX39MQY
[21:57:11] <anarchos2> mould my own vise? :P
[21:57:28] <XXCoder> its cheap!
[21:57:33] <XXCoder> not as effective but...
[21:57:47] <Jymmm> anarchos2: Sorta. You drop the pellets into 180F water and you can shape/mold to your part.
[21:57:59] <Jymmm> totally reuseable too
[21:58:01] <XXCoder> I guess vices can be made
[21:58:05] <anarchos2> i think i'm gonna give the grizzly drill press vise a try
[21:58:12] <anarchos2> amazon is good at taking things back if it's horrible
[21:58:13] <XXCoder> just buy some ACME and mill quality jaws and such
[21:58:27] <Jymmm> anarchos2: They are perfect for odd shaped parts tyou need to clamp down
[21:58:35] <anarchos2> hmm
[21:58:40] <XXCoder> oh just saw TINY table saw at harbor store. lol
[21:58:48] <anarchos2> i need to clamp rectangular aluminum :P
[21:58:51] <XXCoder> its longest dimestion must be around 6 inches
[21:58:58] <Jymmm> XXCoder: ITS VICIOUS
[21:59:00] <XXCoder> blade 3 in dim maybe
[21:59:08] <Jymmm> XXCoder: SCARE STHE FUCK OUT OF ME EVERY TIME
[21:59:11] <anarchos2> my mill moves only 8.5x3.25" :P
[21:59:31] <XXCoder> and pesumely 0 inches z lol
[21:59:54] <anarchos2> Z is the biggest actually, maybe 10"?
[21:59:56] <Jymmm> XXCoder: This is the scary fucker http://www.harborfreight.com/4-in-mighty-mite-table-saw-61608.html
[22:00:17] <XXCoder> lol ok ana
[22:00:24] <XXCoder> jy yeah seems risky
[22:01:07] <Jymmm> XXCoder: Full sized table saw, no problem, This thing... it reminds me of chucky every time I turn it on!
[22:01:20] <XXCoder> lol
[22:02:21] <anarchos2> maybe i should do a border run....grizzly has a show room in bellingham apparently. HF+Grizzly could be some good cheap stuff
[22:03:00] <Jymmm> anarchos2: cheap in more than just price. FYI
[22:03:57] <anarchos2> oh yeah for sure
[22:04:06] <Jymmm> =)
[22:10:56] <FinboySlick> Bleh, hate when that happens.
[22:47:50] <PetefromTn_> jeez I am up late here LOL
[23:06:59] <FinboySlick> PetefromTn_: I won't tell your mom.
[23:08:17] <XXCoder> you better nor or his italian mafia will go after you
[23:09:09] <PetefromTn_> Yeah I need my mom to keep me in check LOL
[23:09:28] <PetefromTn_> She is a formidable force of nature LOL
[23:10:18] <FinboySlick> PetefromTn_: I was about to make another Big Bang Theory reference but I don't think you caught up yet ;)
[23:10:35] <PetefromTn_> hell man I am hardly awake LOL.
[23:10:58] <PetefromTn_> Sitting here on the laptop in bed working on that CAM setup for the new rail. Gonna try to make one tomorrow.
[23:11:23] <PetefromTn_> I am kinda worried about my laptop charger.
[23:11:42] <PetefromTn_> The damn thing gets pretty warm I might even say hot when it is plugged into my laptop.
[23:11:56] <PetefromTn_> Never noticed that before in any of my other computers.
[23:12:14] <XXCoder> PetefromTn_: your battery is probably going bad
[23:12:26] <PetefromTn_> why do you say that?
[23:12:32] <XXCoder> my old laptop its charge goes hot enough to cook egges when trying to charge dead battery
[23:12:45] <XXCoder> try run your laptop without battery see if it dont warm up
[23:12:57] <PetefromTn_> hmm not a bad idea...
[23:13:24] <PetefromTn_> I honestly don't feel any heat from the computer and I use one of those fan pads underneath it.
[23:14:00] <XXCoder> battery dont really warm up much. its charge thats overheating trying to push charge into bad cells in your laptop battery if any
[23:16:16] <PetefromTn_> I will save my shite here and shut down the computer and take out the battery. Not sure if it will run without a battery or not. I would like to be able to remove it and not use it tho even if it is bad just to keep it from dying quicker. I may need to order a new one.
[23:16:29] <PetefromTn_> Trouble is that this has been going on for some time now.
[23:16:44] <PetefromTn_> I would think if the battery was that bad it would have died awhile ago.
[23:17:04] <XXCoder> yeah hard to predict really
[23:17:24] <XXCoder> my aspire one orginial battery is still amazing while my older toshiba one died after just year and half
[23:18:04] <PetefromTn_> I had an aspire for a long time. I loved it but then it died so I got this toshiba.
[23:18:24] <XXCoder> lol sounds like we got em in opposite order
[23:18:24] <PetefromTn_> That Aspire was the 18 inch model screen. I really like that.
[23:18:56] <XXCoder> oh mines aspire one orginial. 8 inch screen I think. come with crappy custom linux that I deleted as soon as I got it
[23:19:11] <XXCoder> it was FIRST to come with ssd drive
[23:19:15] <XXCoder> 8 gb one lol
[23:19:21] <anarchos2> is there any way to "unhome" an axis in the axis gui?
