[00:00:07] <unfy> heh
[00:00:23] <unfy> there are times when i want quality. there are times i want poop.
[00:00:24] <Tom_itx> order all your stuff from china then
[00:00:48] <Tom_itx> you will get poop that glows in the dark
[00:01:05] <unfy> glow in the dark poop is not "quality".
[00:01:06] <zeeshan> unfy:
[00:01:14] <zeeshan> here take this piece of shit chinese dial indicator from me!
[00:01:15] <zeeshan> :P
[00:02:43] <Tom_itx> zeeshan on that drive you linked me the other day that's mains powered, how do you control the DC output voltage on it?

[00:02:52] <unfy> when i wanna actually make something, i'll use quality stuff .. but for dickin around i prefer poop.
[00:02:56] <georgenz> I have quickly (roughly) run thru the pnc conf wiz. And have jst started linux cnc with the file the wiz made. Want to try and jog motor, but axis selections r greyed out, any clues?
[00:04:40] <zeeshan> press enable amp first
[00:05:51] <georgenz> Ok... emerg stop was active. Thx

[00:40:50] <Tom_itx> zeeshan i'm not sure but probably
[00:41:38] <zeeshan> it wants analog
[00:42:09] <Tom_itx> ?
[00:42:14] <Tom_itx> explain
[00:42:22] <zeeshan> +/- 10 v signal
[00:42:24] <Tom_itx> analog for the DC output voltage control?
[00:42:43] <zeeshan> yea
[00:42:49] <zeeshan> so like for example, 0V on the analog input
[00:42:53] <zeeshan> would output 0V dc motor out
[00:42:54] <Tom_itx> he makes a 7i47 that has an analog out iirc
[00:42:59] <zeeshan> but +10v would be..
[00:43:06] <zeeshan> 190V out
[00:43:17] <Tom_itx> i would need to limit it to 90v
[00:43:24] <zeeshan> thats not too hard i'd think
[00:43:30] <zeeshan> you'd just limit your analog signal
[00:43:44] <Tom_itx> how?
[00:44:00] <zeeshan> im sure you can limit it on th ehal side of things
[00:44:01] <Tom_itx> with a voltage divider? to be sure it doesn't exceed the 90v?
[00:44:19] <Tom_itx> or in software...
[00:44:25] <mozmck> I've played with making gladevcp Led's shiny, and the hal_bars as well:
http://postimg.org/image/xqr4nz4d1/
[00:44:37] <Tom_itx> mozmck saw that in devel
[00:44:38] <zeeshan> its a bit of a win/lose situation if you do it in software
[00:44:41] <Tom_itx> good stuff
[00:44:48] <zeeshan> for example you might need to go +/- 5V analg out max
[00:44:51] <zeeshan> but then you lose resolution
[00:44:57] <Tom_itx> zeeshan, i just don't wanna get it if it's not gonna work for my purpose
[00:45:09] <PetefromTn_> hey thats pretty cool!
[00:45:20] <zeeshan> mozmck: send me code!
[00:45:20] <zeeshan> lol
[00:45:22] <zeeshan> that looks awesome
[00:45:55] <mozmck> I'll paste it in a minute. I made the patch against 2.7, and I *think* it will work....
[00:46:38] <zeeshan> Tom_itx: it looks like
[00:46:42] <zeeshan> if you change the reference gain
[00:46:45] <zeeshan> you can limit it that way too
[00:46:51] <zeeshan> there is a pot on it
[00:47:02] <Tom_itx> what's the range on it?
[00:47:19] -!- patrickarlt has quit [Read error: Connection reset by peer]
[00:47:45] <zeeshan> factry it is limited to 60V +/-
[00:47:51] <zeeshan> wait
[00:47:55] <zeeshan> i might be confusing that with the tachometer.
[00:47:57] <zeeshan> i dont know
[00:48:03] <Tom_itx> :/
[00:48:04] <zeeshan> i know its doable
[00:48:13] <zeeshan> how i know is because of this
[00:48:19] -!- patrickarlt has quit [Remote host closed the connection]
[00:48:20] <zeeshan> i hooked up volt meter to motor out terminals without motor connected
[00:48:26] <zeeshan> then i put drive in test mode
[00:48:32] <zeeshan> then i moved the pot around
[00:48:44] <zeeshan> 10V corresponded to ~190Vdc
[00:48:56] <mozmck> Here's the patch for anyone who wants to try it.
http://pastebin.com/1p1kKdbh
[00:49:00] <mozmck> no recompile needed if doing a run in place.
[00:49:19] <zeeshan> i think the easiest way would be to limit in software
[00:49:42] <Tom_itx> i would rather not lose resolutino
[00:49:44] <mozmck> There are properties that have to be set to use the shiny stuff, default is the same as before.
[00:49:53] <Tom_itx> resolution*
[00:50:01] <zeeshan> 4.74V max
[00:50:22] <Tom_itx> yes but if you limit it in software you're gonna limit the res right?
[00:50:36] <zeeshan> resolution will be the same
[00:50:39] <PCW> Is this for a DC spindle motor
[00:50:46] <Tom_itx> for a sherline yes
[00:50:48] <Tom_itx> 90v dc
[00:50:52] <Tom_itx> brush
[00:51:06] <PCW> Ahh do you have 90VDC?
[00:51:08] <Tom_itx> i have the stock control but it lacks reverse
[00:51:19] <Tom_itx> well it's in the stock control from mains
[00:51:29] <Tom_itx> i don't have a separate 90v supply
[00:51:46] <PCW> so no capacitor so no 165V

[00:52:53] <Tom_itx> it might be easier to replace it with a servo

[00:54:49] <PCW> a servo will have a filtered supply and a 4 quadrant drive
[00:55:51] <PCW> the Sherline is probably a SCR phase control or single MOSFET PWM drive
[00:56:59] <Tom_itx> i'm not sure but they probably have a schematic of it somewhere

[01:33:35] <PetefromTn_> hey guys
[01:33:37] <PetefromTn_> question
[01:34:05] <PetefromTn_> my friend in NZ is trying to setup his machine like mine is.
[01:34:18] <PetefromTn_> he is about ready to power up and is workign thru the pncconf
[01:34:43] <PetefromTn_> he ordered the exact same motors and cards and everything that I have but his Z motor is slightly different
[01:34:55] -!- Tom_L [Tom_L!~Tl@unaffiliated/toml/x-013812] has joined #linuxcnc
[01:35:05] <PetefromTn_> I would love to be able to tell him to just load my config but that is probably NOT safe at all
[01:35:43] <Tom_L> http://www.soigeneris.com/Document/Gecko/Using_the%20Gecko_G540_VFD_Output.pdf
[01:35:46] <PetefromTn_> how would you guys recommend he proceed with the understanding that he wants to try to use my working configuration as much as possible. is this not really possible or is it doable
[01:36:02] <Tom_L> that might be a feasable way to convert the stock control
[01:36:23] <Tom_L> ignore the 'mach' references pls
[01:36:37] <zeeshan> how dare you post a mach article

[01:37:05] <zeeshan> pete if he has any of his stuff wired backwards
[01:37:06] <zeeshan> like encoder
[01:37:12] <zeeshan> might cause things to run away :P
[01:37:19] <PetefromTn_> its been long enough since I setup the machine that I do not remember
[01:37:21] <zeeshan> has he checked all that stuff
[01:37:22] <PetefromTn_> AGREED
[01:37:32] <PetefromTn_> that is exactly what I am afraid of.
[01:37:42] <zeeshan> he needs to go through pnc conf
[01:37:44] <PetefromTn_> I recommended to him that he work thru the pnc conf
[01:37:45] <zeeshan> and do an open loop test
[01:37:48] <zeeshan> yea
[01:37:54] <zeeshan> once its all doing what he wants it to
[01:38:08] <zeeshan> he needs to compare the values generated by pnc conf
[01:38:08] <PetefromTn_> I cannot remember how we were able to work with one motor at a time...
[01:38:10] <zeeshan> and compare it with yours
[01:38:49] <PetefromTn_> like when you first complete the pncconf did we just unplug the motors that were not working or what? I cannot remember my memory sucks LOL

[02:18:50] <zeeshan> if i were you
[02:18:56] <zeeshan> i'd just try to pick up a cheap hbridge drive

[02:23:40] <zeeshan> you already have an encoder
[02:23:48] <zeeshan> you could prolly make it run closed loop :-)
[02:24:25] <Tom_L> requires a dc power supply too
[02:24:31] <zeeshan> oh
[02:24:33] <zeeshan> i thought you had one
[02:24:41] <Tom_L> no this runs off mains
[02:25:11] <zeeshan> just use the be25a20ac
[02:25:19] <Tom_L> i may
[02:25:20] <zeeshan> =P
[02:25:28] <Tom_L> i may explore this first
[02:25:31] <zeeshan> i bet there is still a cheaper alternative
[02:25:38] <zeeshan> you dont need a full out closed loop driver
[02:26:01] <Tom_L> i wonder how big a relay i would need
[02:26:21] <zeeshan> relay for what
[02:26:27] <zeeshan> to kill power to drive?
[02:27:01] <zeeshan> man
[02:27:03] <zeeshan> this scares me a bit
[02:27:08] <zeeshan> theres no be25a20ac on ebay
[02:27:16] <zeeshan> i should probably buy a couple extra just incase
[02:27:34] <Tom_L> for reverse
[02:27:57] <zeeshan> you would just send a negative analog signal to reverse
[02:29:12] <Tom_L> not if i used the stock one

[04:34:18] <Tom_itx> i think i should have gotten the 7i47s instead of the 7i47...
[04:34:25] <zeeshan> whats the diff?
[04:34:31] <Tom_itx> spindle control
[04:34:55] <Tom_itx> 12 input 8 output
[04:34:58] <Tom_itx> and spindle
[04:35:44] <zeeshan> i have a speed board
[04:35:45] <zeeshan> if you want.
[04:35:48] <Tom_itx> it's still in the bag.. i repaired my old one and am using it
[04:35:51] <zeeshan> its collecting dust
[04:35:56] <Tom_itx> what is it?
[04:36:05] <zeeshan> nothing great, lemme check
[04:37:36] <zeeshan> http://www.cnc4pc.com/Store/osc/product_info.php?cPath=25&products_id=58
[04:38:19] <zeeshan> its just one extra bs to add
[04:40:04] <Tom_itx> what do you want for it?
[04:40:15] <zeeshan> where are you located
[04:40:17] <Tom_itx> ks
[04:40:22] <zeeshan> its prolly 10 bux to ship
[04:40:28] <zeeshan> you can have
[04:40:40] <Tom_itx> i'm gonna test the input on this thing as soon as i get the controller ironed out
[04:40:57] <Tom_itx> i'm relatively sure it will work
[04:41:05] <zeeshan> if it doesnt 7i47s!!
[04:41:27] <Tom_itx> yeah well if that doesn't work neither will the 7i47s
[04:41:39] <Tom_itx> i debaited getting it when i got the boards
[04:41:43] <zeeshan> what is exactly the controller
[04:41:48] <Tom_itx> wasn't sure what it was
[04:42:03] <Tom_itx> it's the default sherline control with the pot on it
[04:42:13] <zeeshan> ah
[04:42:17] <Tom_itx> i think it will work
[04:42:26] <Tom_itx> acording to that pdf i posted
[04:42:49] <Tom_itx> your link indicates it will as well
[04:43:09] <Tom_itx> it'd be worth ten bucks just to see
[04:43:30] <zeeshan> im never going to use it
[04:43:40] <zeeshan> i thought i needed it
[04:43:43] <zeeshan> i just ended up using modbus
[04:43:54] <zeeshan> and always will in the future
[04:43:56] <Tom_itx> where are you?
[04:43:56] <zeeshan> or 7i76 or 7i77
[04:44:00] <zeeshan> toronto canada
[04:44:03] <zeeshan> newar there

[04:58:26] <Tom_itx> what's the RJ connector for?
[04:59:02] <zeeshan> these guys use rj45 to make wiring simpler
[04:59:07] <zeeshan> between their boards
[04:59:14] <zeeshan> if youre using their breakout board that is
[04:59:35] <Tom_itx> same signals brought out to the screw terminals?
[04:59:43] <zeeshan> yes
[05:00:00] <Tom_itx> i'll probably use those then
[05:02:40] <Tom_itx> i wonder where they expect you to mount that thing
[05:03:11] <Tom_itx> since the motor goes thru the relay it probably would be best to be near it
[05:03:44] <zeeshan> i wasplanning to keep it inthe enclosure
[05:04:02] <zeeshan> i would say its about the same size
[05:04:06] <zeeshan> as the 7i47
[05:04:07] <zeeshan> a bit smaller

[13:35:41] <mrsun_> hmm would you say that pieces not tabbed down when cutting out (profiling etc) has a great risk of breaking bits when they pop lose ?
[13:37:29] <Tom_itx> the possiblity is there but once they cut lose they generally move out of the way since they have the cutter width clearance as a place to go

[13:39:21] <Tom_itx> is there a different way to do it?

[14:54:43] -!- swingley_ has quit [Ping timeout: 255 seconds]
[15:00:10] <archivist> nut needs something to stop it sliding in the clamps
[15:00:30] <Bushman> see the 5'th hole?
[15:00:45] <Bushman> one of those conical counter screws will be there
[15:00:58] <Bushman> just need to drill the nut a bit...
[15:01:09] -!- shurshur has quit [Ping timeout: 264 seconds]
[15:01:28] <Bushman> maybe i will add all the screws to the project later :P
[15:01:40] <archivist> because later you will want to slit the nut to take up wear :)
[15:02:09] <archivist> some have flanges for that
[15:03:55] <Bushman> there are some flanged brass nuts for sale but not with slack/play reduction
[15:04:16] <Bushman> only some plastic ones... and quite pricey compared to this
[15:04:58] <archivist> a single slit in one side of the nut will allow the clamps to adjust a bit
[15:05:09] <Bushman> i know
[15:05:21] <Bushman> but i'm considering other options too
[15:13:31] <Bushman> like cutting the nut in half and making some clever mechanism to rotate one of them a tad and then clamp it back again
[15:16:02] <archivist> or a spring above expected cutting force, I have a worn screw that when adjusted locks up at the ends and is loose in the middle
[15:16:46] <Bushman> yea, i'm worried about that too
[15:16:58] <archivist> on a machine made in 1942, boss said it was almost new!
[15:17:26] <Bushman> lol
[15:17:30] <Bushman> almost
[15:18:32] <archivist> I cannot comprehend how he thought it had done little work
[15:19:31] <Bushman> well, i was working on CNC from 1973
[15:19:59] <Bushman> this bitch had some random twitches
[15:21:14] <Bushman> once when boring cast iron it twitched in the outward direction f***ing up the piece
[15:21:57] <Bushman> and by twitch i mean go few milimeters in random direction and hand up still runing the main motor
[15:22:25] <Bushman> (lathe)
[15:22:46] <Bushman> *hang up
[15:28:53] <archivist> we had a mechanical gear cutting machine at that place too, the dividing would throw an extra bit in for fun now and again

[17:36:06] <Bushman> i'm lazy and there are people who have already modeled those basic parts
[17:36:29] <Bushman> it just happens most of the screws on grabcad are in solidworks format
[17:36:47] <Bushman> like this one:
https://grabcad.com/library/caphead-bolt-and-dowel-set-1/files/M4%20x%2040mm%20CAPHEAD%20BOLT.SLDPRT
[17:36:59] <Bushman> pretty much what i need
[17:37:25] <Bushman> i could fix my model to accept those directly in no time.

[19:07:29] <DGMurdockIII> Hi guys
[19:08:24] <DGMurdockIII> Any one now any good cnc drill bit starter kits
[19:10:54] <archivist> I dont remember ever seeing a drill kit aimed at cnc
[19:11:09] <XXCoder> yeah probably standard kits would do?
[19:11:18] <XXCoder> like at lowes or something
[19:12:17] <renesis> go to harbor freight and get the titanium nitride full set
[19:12:27] <PetefromTn_> while I am LOATHE to say it harbor freight now sells a cobalt mix drill index set for like a hundred bucks that is not bad. If you get one of these you can have a good start
[19:12:32] <renesis> fractional, lettered and numbered, theyre HSS
[19:12:37] <archivist> probably more important to get the right drills for the materials you work with
[19:12:49] <renesis> then as you wear them out, replace with the import stuff at enco
[19:13:07] <renesis> its the harbor freight stuff is about the same quality as enco import stuff

[19:13:22] <DGMurdockIII> Was looking at that
[19:13:42] <PetefromTn_> you said drill bit kit
[19:13:43] <renesis> yeah thats some crazy shit
[19:13:45] <renesis> ya
[19:14:26] <renesis> thats expensive
[19:14:45] <renesis> you can buy most of that shit individually for less
[19:14:45] <_methods> they like to rob sign people
[19:14:55] <_methods> they know they don't know any better
[19:15:28] <_methods> poor woodworkers get it too
[19:15:30] <DGMurdockIII> Yeah I now that $$
[19:15:37] <renesis> like, id rather have 5 of the endmill that i need than a set of 10 random ones, one each
[19:15:42] <_methods> i see them sell them cat40 toolholders for silly prices
[19:15:58] <_methods> they could buy them from msc for cheaper and msc is still a rip off

[19:19:03] <DGMurdockIII> I just need stuff to cut metal and plexiglass
[19:19:16] <renesis> ive gotten half round and pyramid engraving cutters from them, stuff with .005 tips, worked great
[19:19:26] <renesis> okay well also there is...
[19:20:40] <DGMurdockIII> To make boxes or holes in then
[19:20:49] <renesis> http://www.ebay.com/itm/3mm-Shank-3mm-CED-Tungsten-Carbide-Cutter-Rotary-File-Bur-Burr-Grinding-20Pcs-/161261902056?pt=LH_DefaultDomain_0&hash=item258bf558e8
[19:21:51] <_methods> what kind of machine are you using to cut this stuff with?
[19:21:57] <renesis> http://www.ebay.com/itm/5-PCS-YG1-4-FLUTE-SOLID-CARBIDE-1-8-DIAMETER-END-MILL-X-1-2-LOC-X-1-1-2-CNC-BIT-/130911760434?pt=LH_DefaultDomain_0&hash=item1e7af2f032
[19:22:07] <DGMurdockIII> I'll show u
[19:22:34] <_methods> for plexi i'd get those single flute upcut bits
[19:23:08] <renesis> guy selling carbide on ebay is gone
[19:23:26] <_methods> and the type of metal you are cutting will determine what you need for end mill geometry
[19:23:40] <renesis> plexi you just want to keep it cool
[19:23:41] <_methods> so hard to recommend end mills without knowing what metal you plan to cut
[19:24:22] <renesis> either feed fast and spin kind of medium slow, or use water based lube or something
[19:24:29] <renesis> dish soap works
[19:27:00] <DGMurdockIII> http://www.cncrouterparts.com/standard-cnc-machine-kits-c-46_29.html
[19:27:19] <DGMurdockIII> That the machine
[19:28:10] <renesis> the uprights are steel?
[19:28:24] <renesis> for a lighter machine thats looks pretty good
[19:29:31] <DGMurdockIII> Yes i think there steel
[19:30:47] <_methods> so you want to mill aluminum and plexiglass?
[19:31:09] <_methods> most of the stuff renesis just recommended will work well on that machine

[19:38:09] <renesis> dgmurdockiii: but yeah for aluminum, i would get a bottle of rutlick water based lube and itll last forever, mix it in a spray bottle, and just squirt
[19:38:42] <DGMurdockIII> Ok
[19:38:44] <renesis> and ive used that and just regular dish soap
[19:38:51] <renesis> for acrylic
[19:39:33] <renesis> and i mostly use 4 flute carbide endmills for everything
[19:40:08] <roycroft> i use wd40 when machining aluminium
[19:40:11] <renesis> i guess some people have all sorts of reasons to use shit other than carbide, but fuck that for little cnc
[19:40:20] <roycroft> it works better than anything else i've ever tried
[19:40:38] <renesis> yeah i dont like the smell and my machine is in a studio apartment
[19:40:48] <renesis> it does work well as a cutting coolant, tho
[19:40:57] <renesis> prob its best use by far
[19:40:59] <roycroft> it does have a strong odor
[19:41:03] <renesis> yeah
[19:41:15] <roycroft> i machine in a garage with a big door
[19:41:19] <renesis> i like it but itll give me a headache =\
[19:41:59] <renesis> but yeah, carbide breaks, its doesnt wear
[19:42:19] <renesis> like, the tips will chip off, and leave a sharp edge, and itll still cut
[19:42:30] <renesis> finish will be ass, might loud as fuck, but itll cut
[19:42:56] <roycroft> except when you're doing a plunge cut and it breaks off inside the part
[19:42:56] <renesis> hss and similar will wear down, and they kind of stop cutting and start chewing and it loads down the machine bad
[19:43:11] <renesis> and i have an open loop step machine so loading like that is the enemy
[19:43:23] <renesis> yeah dont do that
[19:43:34] <renesis> i usually do little spirals

[20:23:22] <renesis> i cut it like maybe 20:1
[20:24:01] <CaptHindsight> yeah ~50% water the rest is oils, waxes and some soap to disperse them

[20:59:59] <XXCoder> bulk cards is cheaper
[21:00:14] <XXCoder> with 100k backers thats 100k decks, big bulk = more profit per deck
[21:00:54] <zeeshan> dont b jealous!
[21:01:03] <Jymmm> He could even have them made in the US, as cutomsdecks are very common (think casinos)

[21:03:43] <Jymmm> CaptHindsight: card games?
[21:03:52] <CaptHindsight> card and board
[21:04:47] <CaptHindsight> printing those decks will cost a few $$ ea

[21:05:34] <CaptHindsight> seel/sell
[21:06:31] <CaptHindsight> $35 for a pair of decks
[21:07:05] <XXCoder> nfsw will be only part deck, unless over 100k backers, which will happeb

[21:42:33] <Jymmm> PetefromTn_: thanks.
[21:42:35] <PetefromTn_> I think you can get the idea tho...
[21:42:37] <PetefromTn_> sure man.
[21:42:49] <renesis> petefromtn_: no the other way
[21:43:01] <renesis> more light, not less, so theres less of a diff
[21:43:14] <PetefromTn_> maybe..
[21:43:34] <PetefromTn_> I think you can get the idea tho from the video.. that is actually like the fourth try at the video LOL
