[00:00:02] <zeeshan> 30 sec before that
[00:00:03] <jthornton> yea once I got over the inital hump it is pretty easy
[00:00:12] <jthornton> initial
[00:00:22] <ssi> yeah it's very easy
[00:00:26] <ssi> it's quick to write powerful stuff
[00:00:32] <Tom_itx> CaptHindsight, wipe off the grease and take another pic for us :)
[00:00:47] <ssi> I'm back in the realm of embedded C, which is the opposite of that :)
[00:01:00] <ssi> I've been sweating over multiple indirection pointers and bit packing all day
[00:01:01] <Tom_itx> for what chips?
[00:01:08] <ssi> stm32f4
[00:01:12] <Tom_itx> arm
[00:01:15] <ssi> yes
[00:01:19] <zeeshan> youre an arm
[00:01:23] <CaptHindsight> ^^ one of those used super precision rotary tables for 1/12th the cost of new
[00:01:35] <ssi> zeeshan: thank you?
[00:01:37] <Tom_itx> better grab it

[00:03:10] <zeeshan> gimme!!!!!!1
[00:03:59] <Sync> zeeshan: hm, not super impressed with the machines
[00:04:09] <zeeshan> i just saw a video of it eating aluminum
[00:04:18] <zeeshan> another machine had a er32 collet system on it
[00:04:18] <zeeshan> lol

[00:12:05] <ssi> Sync: so rene wrecked my world with the input/output thing earlier
[00:12:12] <Sync> 0o
[00:12:14] <ssi> now I have to re-read all the smartserial docs and try to figure out where it all went wrong :(

[00:13:59] <Sync> ):
[00:14:15] <ssi> it's really confusing keeping tx/rx and input/output straight when working on the remote end
[00:14:34] <ssi> and I thought I had it all sorted out, everything is by convention named from the host end
[00:14:40] <zeeshan> what are you doing
[00:14:40] <ssi> so inputs are inputs FROM the remote TO the host
[00:14:45] <ssi> but apparently that's not right
[00:14:53] <ssi> furthermore, it seems like it might be inconsistent in the docs
[00:14:59] <ssi> zeeshan: same thing I've been doing
[00:15:15] <zeeshan> cnc mill?:
[00:15:15] <zeeshan> d
[00:15:20] <ssi> yes
[00:15:48] <ssi> hm no, the manual definitely agrees with what I expected
[00:15:56] <ssi> The DATA_DIRECTION field is a single byte field that specifies the data direction. Valid Data direction bytes are as follows:
[00:16:14] <ssi> 0x00 INPUT (Read from remote)
[00:16:21] <ssi> 0x80 OUTPUT (Written to remote)
[00:16:48] -!- R2E4_ [R2E4_!~IceChat9@modemcable164.157-20-96.mc.videotron.ca] has joined #linuxcnc
[00:16:56] <ssi> but he's basing that on the fact that show hal configuration shows IN/OUT backwards from what we expected
[00:17:25] <ssi> and now that I'm looking at it, that's correct
[00:17:30] -!- SpNg has quit [Quit: SpNg]
[00:17:41] <ssi> cmd_vel shows up as IN, because you would wire a source to it
[00:17:46] <ssi> it's a hal pin that receives a value
[00:18:03] <ssi> but from the perpective of the sserial driver, it's an output to the remote
[00:18:41] <R2E4> Anyone doing Gantrykins here?
[00:19:08] <ssi> R2E4: I am
[00:19:50] <ssi> Sync: I feel SO MUCH BETTER now :D

[00:21:43] <R2E4> Do I need two Axis Y section in HAL?
[00:21:55] <ssi> R2E4: are you running joints_axes branch?
[00:22:19] <R2E4> I set it up to what I think it should be and joint 2 is acting like joint 1 is suppoe to be.
[00:22:26] <R2E4> no
[00:22:40] <ssi> I have only done gantrykins successfully with ja
[00:23:19] <Tom_itx> ssi, easy mistake to make on the IO
[00:23:42] <ssi> yeah
[00:23:46] <ssi> he was certain I had it all wrong
[00:23:49] <Tom_itx> i had to doublecheck the wiring the first time
[00:23:52] <ssi> I was gonna pull my hair out if that was the case
[00:24:03] <ssi> because the input and output bytes in discoveryrpc are definitely named wrt the host
[00:24:17] <ssi> it would be sheer madness if the input/output flags in the descriptors were backwards wrt that convention
[00:24:18] <Tom_itx> i got a 7i84 i need to check one of these days
[00:24:38] <Sync> ah, confusing for sure ssi
[00:24:45] <Sync> zeeshan: halp!
[00:25:05] <R2E4> ssi: did you try gantrykins with stable branch?

[00:25:44] <R2E4> I cant load a beta version on customer system.
[00:25:57] <ssi> ja isn't exactly beta
[00:26:15] <ssi> I wasn't satisfied with the options for doing a gantry machine without ja
[00:26:21] <Tom_itx> you implementing it on an arm?
[00:26:23] <ssi> there's ways to do it, but none of them pleased me
[00:26:24] <Tom_itx> sserial
[00:26:27] <R2E4> are you running gantrykins or gentrivkins?
[00:26:30] <ssi> Tom_itx: yes
[00:26:34] <ssi> R2E4: ah sorry gentrivkins
[00:26:45] <Tom_itx> would make a nice frontend for a number of things
[00:27:05] <R2E4> Does Gantrykins work?
[00:27:06] <ssi> Tom_itx: yeah once I have it fully understood it could be ported to other projects
[00:27:15] <Tom_itx> exactly

[01:02:38] <ssi> well crap, I seem to have crashed the arm, and I can't reconnect with term anymore :(
[01:03:13] <Tom_itx> woops
[01:04:16] <ssi> yeah that's not good :(
[01:04:26] <Tom_itx> R2E4, http://linuxcnc.org/docs/html/man/man9/gantrykins.9.html
[01:04:29] <Tom_itx> The coordinates= parameter specifies the initial gantry joint mapping. Each axis letter is mapped to a joint, starting from 0. So coordinates=XYYZ maps the X axis to joint 0, the Y axis to joint 1 and 2, and the Z axis to joint 3.

[01:07:52] <ssi> can't get term to connect, not for anything
[01:07:59] <Sync> is the device there?

[01:08:22] <ssi> doesn't look like it

[01:08:42] <ssi> oddly, it looks like the device is responding over smartserial
[01:09:00] <Sync> for me the usb stuff was flaky as well
[01:09:22] <Sync> the nextgen™®© hardware will have the option of rs422/485 for the term
[01:09:27] <R2E4> Tom, I read that,
[01:09:51] <ssi> this is frustrating... I kinda need the term
[01:10:11] <Sync> I feel you
[01:10:29] -!- Loetmichel has quit [Ping timeout: 250 seconds]
[01:10:35] <Sync> hm, can you still flash it through the dfu?
[01:10:42] <ssi> yes I can flash it
[01:10:47] <ssi> I've been using the stlink for all my flashing
[01:10:47] <Sync> hmm
[01:10:50] <R2E4> Why does it only show 3 joints in axis when I clearly have 4 programmed.
[01:10:54] <Sync> ah
[01:10:59] <ssi> and it seems to be running happily despite having no term
[01:11:03] <Sync> because you can use the dfu to flash it over usb
[01:11:07] <ssi> oh I haven't tried that
[01:11:34] <Tom_itx> does it have a bootloader?
[01:11:39] <Sync> of course
[01:11:45] <Tom_itx> yeah dfu should work then
[01:11:51] <Tom_itx> i'm not familiar with arm
[01:12:21] <Sync> most if not all of them come with a serial bootloader, the ones featuring usb usually have dfu too
[01:12:25] <zeeshan> dfu?
[01:12:32] <Sync> device firmware update
[01:12:34] <zeeshan> ah
[01:12:40] <Sync> or something like that
[01:12:43] <ssi> it's teh "device is fucked up" mode
[01:13:15] <zeeshan> i dunno where ive seen that term before
[01:13:33] <ssi> ever use a smartphone? :P
[01:14:01] <zeeshan> yes
[01:14:06] <zeeshan> i think it was when jail breaking iphone
[01:14:09] <ssi> there you go

[01:14:25] <ssi> http://i.imgur.com/1F8gw3T.jpg
[01:14:32] <zeeshan> the other night i was thinking
[01:14:35] <zeeshan> why do people call it torque control
[01:14:36] <zeeshan> and speed control
[01:14:47] <zeeshan> could you not also call it current control and voltage control? :D
[01:14:54] <ssi> current control, yes
[01:15:02] <ssi> and torque/current are used somewhat interchangeably
[01:15:03] <Sync> voltage, not so much
[01:15:07] <ssi> I don't tihnk voltage control is accurate
[01:15:10] <zeeshan> but isn't that speed control?
[01:15:12] <ssi> no
[01:15:16] <zeeshan> you vary the pulse of voltage
[01:15:18] <zeeshan> and amplitude
[01:15:28] <zeeshan> duration and amplitude i mean
[01:15:41] <Sync> just because you apply a voltage does not mean the motor spins at n rpm
[01:15:51] <ssi> yeah, the kv constant is specified unloaded
[01:16:05] <Sync> it just gives you the maximum no load rpm
[01:16:13] <ssi> and since the motor is a relatively constant impedance, the current is going to vary in proportion to the voltage
[01:16:23] <ssi> so there's not really any such thing as current control vs voltage control, they're two sides of the same coin
[01:16:53] <Sync> well, that also depends
[01:16:59] <ssi> it does
[01:17:01] <Sync> on how your control algo works
[01:17:06] <Sync> some output a voltage
[01:17:06] <ssi> but for the purposes of zee's point it's accurate enough :)
[01:17:13] <Sync> and some actually control the current
[01:17:22] <zeeshan> no i mean like
[01:17:28] <zeeshan> in one you're controlling current and voltage can be whatever
[01:17:34] <Sync> negative
[01:17:43] <ssi> zeeshan: go apply a voltage to a resistor
[01:17:45] <Sync> the voltage will be the same
[01:17:49] <ssi> then go apply a current to the same resistor
[01:17:56] <ssi> and tell me that you can control them independently
[01:18:00] <zeeshan> youre thinking of it steady state
[01:18:09] <zeeshan> if you give pulses of current
[01:18:11] -!- skunksleep has quit [Ping timeout: 264 seconds]
[01:18:18] <Sync> which average to a given current
[01:18:22] <zeeshan> you can control thje torque
[01:18:30] <Sync> your cutoff frequency is way lower than your pwm frequency
[01:18:37] -!- justanotheruser has quit [Read error: Connection reset by peer]
[01:18:39] <ssi> at the lowest level, all you're ever doing is controlling the current
[01:18:42] <Sync> so you can look at it as if it was steady state
[01:18:49] <ssi> which loop you close depends on the type of feedback you have and what you use as your process variable

[01:20:50] <Sync> for equal loads, the currents/voltages are equal zeeshan
[01:20:56] <zeeshan> i know that
[01:20:58] <zeeshan> silly :P
[01:20:59] <zeeshan> read the paper
[01:21:06] <zeeshan> its not long!
[01:21:28] <Sync> I don't need to
[01:21:32] <zeeshan> Torque control, based on manipulation of DC motor current, utilizes usually a current + am lifier in the motor's drive unit. A current amplima device w ich supplies a current proportional to its input voltage, and has a high output resistance.
[01:21:43] <zeeshan> cause what you guys are saying doesnt agree w/ what this dude is sayin
[01:22:05] <zeeshan> The alternative approach is to control the speed of the robot arm by manipulation of the DC motor voltage, utilizing a voltage am lifier in the motor's drive unit. Similar approach is +. usua y used in hydraulic driven robots. A voltage amplifier provides an output voltage proportional to its input voltage, and is capable to supply the current required by the motor.
[01:22:12] <zeeshan> there i pasted relevant text
[01:22:18] <zeeshan> mr i don't need to read
[01:23:30] <Sync> that is what we already said
[01:23:34] <zeeshan> no
[01:23:42] <zeeshan> you said i wasn't correct
[01:23:55] <Sync> you are misinterpreting it
[01:24:01] <zeeshan> by saying torque control is like controlling current
[01:24:15] <Sync> that is still true
[01:24:26] <zeeshan> what was the point you were making
[01:24:28] <zeeshan> cause i didnt get it
[01:24:30] <zeeshan> =/
[01:24:54] <Sync> controlling velocity is not voltage control
[01:25:30] <Sync> the point he makes is, you can use a voltage amplifier to control velocity
[01:25:58] <ssi> which is what a velocity mode servo amplifier is
[01:26:06] <ssi> you need velocity feedback to do it
[01:26:28] <ssi> whereas a current mode drive can get its feedback directly from the motor power lines
[01:26:35] <ssi> via current sensing and back emf
[01:26:42] <zeeshan> oh no that is not what i meant
[01:26:53] <zeeshan> both these control need feedback from a real encoder
[01:27:00] <Sync> no
[01:27:02] <ssi> current mode doesn't
[01:27:06] -!- asdfasd1 has quit [Ping timeout: 240 seconds]
[01:27:07] <ssi> and velocity mode only needs a tacho
[01:27:11] <ssi> or encoder or any other vel fb
[01:27:16] <Sync> a torque controller only needs a current value
[01:27:46] <ssi> the difference is that torque is proportional to current, whereas velocity is not proportional to voltage
[01:28:10] <zeeshan> what is it proportional to
[01:28:13] <zeeshan> (voltage)
[01:28:18] <zeeshan> i always thought it was voltage!
[01:28:21] <zeeshan> times some constant
[01:28:27] <ssi> yes, the kv constant
[01:28:29] <ssi> that's true unloaded
[01:28:32] <ssi> it's not true dynamically
[01:29:26] <ssi> I guess I'mma rebooit this machine and hope usb will come back up on term

[03:21:18] <Tom_itx> PetefromTn_, those are probably not a full 5A
[03:21:38] <Tom_itx> it depends on the choke used

[03:24:58] <ssi> sorry I'm not more help, but it's been a few years since I did it, and I'd have to dive back in and read up to do it again
[03:25:10] <Tom_itx> i made a 3A 5v fixed version of it myself
[03:25:13] <ssi> and right now I'm elbows deep in sserial code so I don't really have time to go learn it so I can teach it

[03:25:53] <Tom_itx> git checkout xxx
[03:28:15] <Tom_itx> PetefromTn_, somewhere in that pdf it shows performance curves for various chokes

[03:29:41] <PetefromTn_> Tom_itx so I suppose its not a great idea then

[03:30:16] <Tom_itx> i got a couple different chokes when i was doing mine
[03:30:19] <PetefromTn_> what would you do go with the 24v 20 pin and use that harness to make it fit or something else
[03:30:35] <Tom_itx> i'd ask em if you can do that
[03:30:55] <Tom_itx> if they say yes, i'd get the pico psu one at 36v probably
[03:30:58] -!- Duc has quit []
[03:31:09] <PetefromTn_> I was looking again at the meanwell power supplies that 350 amp one would be nice even tho its not Din rail mount
[03:31:10] <Tom_itx> or put a wart on it like i did and run 12v
[03:31:44] <Tom_itx> the 8A wart has a fan in it
[03:31:50] <Tom_itx> i don't think mine ever came on
[03:31:57] <Tom_itx> the 5A one doesn't
[03:32:16] <PetefromTn_> yeah I don't really want to do that If I am going to use DC to power the PC I want it to be something like that picopsu setup
[03:32:49] <Tom_itx> then tap into your supply to get a suitable v source
[03:33:15] <Tom_itx> are you running a switcher supply?
[03:33:18] <Tom_itx> or linear?
[03:33:28] <PetefromTn_> I have not bought the supply yet
[03:33:50] <Tom_itx> i used linear on mine because the stuff was surplus, available and cheap
[03:34:24] <PetefromTn_> honestly the meanwells look nice and I could get a 24v and a 12v for under a hundred probably and then use one of those boards to step down to 5v for the mesa card
[03:34:50] <Tom_itx> i will tell you the chinese ones don't have thermal or over v shutdown
[03:34:58] <Tom_itx> don't ask how i know :D
[03:35:15] <PetefromTn_> I thought they did? the meanwells are chinese no?
[03:35:28] <Tom_itx> they're supposed to
[03:35:38] <Tom_itx> i'm talking about that buck think you posted
[03:35:45] <Tom_itx> thing*
[03:35:55] <PetefromTn_> yeah it would only be for 5v logic in this instance
[03:35:57] <Tom_itx> http://www.ebay.com/itm/DC-DC-Step-down-Buck-Converter-Adjustable-Power-4V-38V-to-1-25V-36V-5A-Voltmeter-/171445007919?hash=item27eaeb362f:g:qBwAAOxyNThTcwQm
[03:36:09] <Tom_itx> should work fine for the 5v stuff
[03:36:14] <Tom_itx> that's what i'm using
[03:36:17] <PetefromTn_> I would hope so
[03:36:41] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/5v_switcher.jpg
[03:36:43] <Tom_itx> same chip
[03:36:47] <PetefromTn_> the question is then if I get TWO DC supplies one 12 and one 24 they both do not need to be too big really
[03:36:48] <Tom_itx> fixed 5v out
[03:37:14] <Tom_itx> i tapped off my 24v to get my 10v needed for my spindle dac
[03:37:40] <Tom_itx> my xfrmrs had a centertap

[03:39:26] <PetefromTn_> those two
[03:39:45] <PetefromTn_> and that board for 5v and a 12v 24pin picopsu
[03:39:53] <Tom_itx> this is to control what?
[03:40:01] <Tom_itx> err supply rather
[03:40:02] <PetefromTn_> basically everything
[03:40:13] <PetefromTn_> PC and 24v field
[03:40:27] <PetefromTn_> possibly the monitor too if I can figure out how
[03:40:33] <Tom_itx> you don't need alot for either one of those
[03:40:44] <Tom_itx> unless you have alot of power hungry relays
[03:40:47] <PetefromTn_> Oh and my contactor/relays
[03:42:19] <PetefromTn_> that's only like $125 for all three items pretty cheap really and should be MORE than enough to run that stuff and anything else I ever decide to plug in most likely
[03:43:07] <Tom_itx> so all you need is 12 & 24v?
[03:43:08] <PetefromTn_> the other option is smaller of the same ones in Din rail mounts but they are a bit more money for less watts
[03:43:13] <Tom_itx> and a buck for the 5v
[03:43:19] <PetefromTn_> 12,24,5
[03:43:22] <Tom_itx> besides your drives
[03:43:33] <PetefromTn_> drives are all AC
[03:43:38] <Tom_itx> what's on 12v?
[03:43:58] <PetefromTn_> well the PC would be because they do not make that damn connector in 24v 24 pin
[03:44:28] <Tom_itx> why get that big arse supply when a wart would work for that?
[03:44:37] <Tom_itx> then all you need is the 24v one
[03:44:44] <Tom_itx> and wire the buck to that for the 5v
[03:44:54] <PetefromTn_> I don't like putting warts inside a commercial machine
[03:45:45] <PetefromTn_> I am sure they would probably work fine
[03:46:05] <Tom_itx> too bad you can't find one that has 24 & 12 out together
[03:46:12] <Tom_itx> i'm sure they make em
[03:46:41] <PetefromTn_> simplest would be JUST that big 24v supply and the picopsu in 24v 20 pin to that connector cable
[03:47:06] <Tom_itx> if you can get by with 20 pins

[04:01:23] <PetefromTn_> hang on let me look at my monitor I have here...
[04:02:58] <Tom_itx> and if it's run off AC you don't have to worry about replacement if it gets broken

[04:03:44] <PetefromTn_> the one in the Cincinatti is a wall wart 12v 1.5amp
[04:03:45] <Tom_itx> then power isn't an issue on the monitor

[04:16:59] <PetefromTn_> would like to use Din mount power supplies as well
[04:17:15] <PetefromTn_> I think that is a reasonable setup tho
[04:17:32] <PetefromTn_> they sell a 100watt 12v one too for another 20 bucks or so
[04:17:44] <Tom_itx> you should have ample room for it all in the enclosure
[04:17:54] <PetefromTn_> http://www.automationdirect.com/adc/Shopping/Catalog/Power_Products_(Electrical)/DC_Power_Supplies/5VDC,_12VDC,_48VDC,_DIN_Rail_Mount/PSB12-100
[04:17:57] <Tom_itx> make sure you isolate things for noise
[04:18:13] <PetefromTn_> oh yeah man there is TONS of room in there for everything
[04:19:03] <Tom_itx> they give you cad drawings for those too
[04:19:07] <PetefromTn_> I plan to put the VFD down near the bottom of the cabinet, the drives in the middle, and the rest of the stuff at the top
[04:19:49] <PetefromTn_> makes sense because the main spindle motor is down near the bottom of the base of the machine and the power leads go thru from underneath the electronics enclosure
[04:20:41] <Tom_itx> early day tomorrow.. later
[04:20:51] <PetefromTn_> thanks man good night

[05:05:38] <MacGalempsy> anything exciting going on?
[05:05:54] <ssi> sserial code
[05:08:00] <MacGalempsy> that doesnt sound exciting
[05:08:04] <ssi> you'd be surprised :)
[05:09:59] <MacGalempsy> exciting as keeping you thinking?
[05:10:09] <ssi> wat
[05:10:19] <ssi> it's actually exciting
[05:10:32] <ssi> I just wrapped up a new scheme for building the tocs and memory space of the remote, and I'm pleased with myself
[05:11:02] <MacGalempsy> i working on some 3d printer estimates. I got a phone interview with a school district about getting printers in the classrooms
[05:11:16] <ssi> what sort of printers are you getting for them
[05:11:44] <MacGalempsy> well, it is more of a seminar where we end up building one in class.
[05:12:02] <ssi> so one of the prusa variants then I guess? or what
[05:12:21] <MacGalempsy> trying to get three price ranges. prusa i3, somehting similar with extruded aluminum and maybe a kossel
[05:12:42] <ssi> kossel aka "rip off ssi"
[05:12:55] <MacGalempsy> figure good price points will be $799, $999, and $1399
[05:13:09] <MacGalempsy> that is the class, a printer and 2 rolls of filament
[05:13:28] <ssi> that's pretty cool
[05:13:31] <MacGalempsy> didnt know that kossel was a ripoff ssi
[05:13:46] <ssi> heheh I did the first rostock-style delta built with extrusion
[05:13:49] <MacGalempsy> the main point is getting them lined up with zero prior experience
[05:13:53] <ssi> but I didn't really pursue it
[05:14:03] <MacGalempsy> nice
[05:14:44] <MacGalempsy> the hopes is to target 3 markets here: university students, school districts, and walmart corporates
[05:14:54] <MacGalempsy> workers, not the company
[05:15:25] <MacGalempsy> just trying to get the wholesale costs down in the next few days, then build three models to demo
[05:16:01] <MacGalempsy> with the prusa i3, it would be nice to do a single build plate in 1.8" aluminum
[05:16:05] <MacGalempsy> 1/8"
[05:16:07] <MacGalempsy> heh
[05:17:05] <MacGalempsy> but the cheapest frame I can find at the moment is like $75 for the frame and platform. if anyone here wants to give me an estimate for 12 framesets, lets talk!
[05:19:04] <ssi> lol
[05:20:03] <MacGalempsy> the rest of the stuff I can source pretty easily.

[06:40:45] <Wolf_> how about crazy priced hinges http://www.ikea.com/us/en/catalog/products/40279477/
[06:42:02] <renesis> those look cool
[06:42:40] <Wolf_> they are, just installed a pair in a upward opening over the fridge cabinet
[06:43:02] <renesis> fuck i wonder how muc shelves are for the ikea closet pantry thing my apartment came with
[06:44:04] <Wolf_> shelves and cabinets are pretty cheap, drawer systems and hinges aren’t because they are mostly made by Blum
[06:45:39] <renesis> thats not bad, $35 for a pair of shelves and the little hanging nubs

[12:56:33] <jthornton> yea in SW
[12:56:45] <_methods> you post up the files?

[13:00:54] <_methods> that sucks
[13:01:05] <Wolf_Mill> saving some of the good wall studs tho
[13:02:20] <_methods> that looks like quite an undertaking

[13:04:33] <_methods> old lath walls?
[13:04:42] <Wolf_Mill> yup
[13:04:45] <_methods> ugh
[13:04:56] <Wolf_Mill> took all that crap out in the first 2 months
[13:05:43] <Wolf_Mill> seems no one wanted to touch that stuff, electrical and plumbing inthe house was a mess due to it
[13:05:50] <_methods> you have to rewire everything?
[13:06:06] <Wolf_Mill> yup, was only 5 outlets in the whole house
[13:06:13] <_methods> heh

[16:53:21] * JT-Shop knows nothing about gmoccapy
[16:53:48] <DaPeace> but maybe a little about hal-programming?
[16:54:13] <micges> DaPeace: halui have pins showing current mode
[16:54:14] <_methods> yeah the tap will work fine with coolant
[16:54:14] <cradek> halui can switch modes. you should hook your buttons to that.
[16:54:45] <DaPeace> hmm.. ive tried that.. but it is not switching mode in the gui of gmoccapy
[16:55:46] <DaPeace> gmoccapy has button-pin gmoccapy.v-button-3 and v-button-5 that i need to toggle between and i cant really figure out how that would work the easiest way.. only find examples that need a status-pin..
[16:57:25] <JT-Shop> are the buttons connected in hal now?
[16:57:46] <DaPeace> nope.

[17:03:56] <anomynous_> whats the best short caliper one can find?
[17:04:15] <DaPeace> another question.. is it possible to use the pause/resume-button as cycle-start-button too?
[17:04:45] <JT-Shop> start/stop?
[17:04:52] <JT-Shop> I would assume so
[17:05:00] <DaPeace> more something like start/pause/resume

[17:09:26] <JT-Shop> there is an example on the forum
[17:10:08] <DaPeace> could you give me the link?

[17:13:33] <DaPeace> but i dont find anything about three signals.. only pause/resume.. no start/pause/resume
[17:13:49] <JT-Shop> yea I've only seen 2
[17:14:30] <DaPeace> maybe i ask at the forum.
[17:14:55] <JT-Shop> yea folks have more time to think and answer on the forum
[17:15:45] <DaPeace> thank you anyway
[17:16:27] <JT-Shop> np, I just didn't have time to give long answers right now
[17:17:31] <DaPeace> normaly i dont bother people with questions that could easily be answered by google.. but linuxcnc is a little tricky and not so well documented.
[17:18:11] * JT-Shop cries
[17:21:10] <cradek> my experience is that people who say that haven't looked at the actual docs in much depth. if you just start with google it would be easy to miss the good actual docs.
[17:21:34] <cradek> a web forum is not documentation
[17:21:47] <DaPeace> main problem is that for a noob like me, the documentation is some kind of rocketscience..

[17:36:43] <DaPeace> more or less.. yes..
[17:36:44] <maxcnc> the logs say somthing like Pause/resume
[17:37:00] <maxcnc> you can do logics with and or
[17:37:05] <DaPeace> yep. pause-resume is working.. but want to add cycle-start to the same button..
[17:37:30] <maxcnc> then its best to use Multiclick
[17:37:46] <maxcnc> there you got 7options on one button
[17:37:50] <DaPeace> ive opened a thread in forum for that too.. did not find any example how to add 3 different states to one button
[17:38:14] <DaPeace> multiclick? how das that work? any example or something to read for me?
[17:38:14] <_methods> one button to rule them all
[17:38:17] <maxcnc> i do that al the time on my HB04
[17:39:15] <maxcnc> i got 8 functions one the STEP button to set the speed and direct via MPG ore Jogbuttons
[17:39:52] <maxcnc> DaPeace: http://linuxcnc.org/docs/html/man/man9/
[17:40:00] <maxcnc> here are more comen infos
[17:40:02] <DaPeace> yeah. im really sure with the given methods its not impossible to do that.. but im about to discover how that would work.. *g*
[17:40:15] <maxcnc> add that side to your Faf list
[17:40:39] <maxcnc> look at multiclick
[17:40:39] <DaPeace> ahh.. multiclick.. ok. thats something we have at our machines at work too..
[17:41:42] <DaPeace> thanks for the tip.. thats not really what i was searching for but might be usefull for some other stuff at the machine..
[17:41:45] <maxcnc> is for safty reasens
[17:41:54] <maxcnc> only start the mashine on 2clicks
[17:42:04] <maxcnc> but one one click Estop ;-)
[17:42:19] <maxcnc> look also at updown
[17:42:25] <DaPeace> problem is that i need something like "if machine is idle -> start it, if machine is started -> pause it, if machine is paused -> resume it" and the missing part for me is the first..
[17:42:34] <maxcnc> your button triggers a updown Var
[17:43:39] <maxcnc> DaPeace: somthing like that net button-start-pause xhc-hb04.button-start-pause => flipflop_pause.clk flipflop_resume.clk flipflop_run.clk
[17:44:40] <DaPeace> yes
[17:45:34] <Erant> I'm setting up a 5i25 with a 7i78, but it looks like the firmware doesn't come with LinuxCNC?
[17:46:10] <pcw_home> the firmware is in the 5I25 card
[17:46:39] <maxcnc> DaPeace: http://pastebin.com/84QZhyHn
[17:46:40] <pcw_home> (and if you need to change it you use the mesaflash utility)
[17:47:20] <Erant> What's the default?
[17:47:25] <_methods> i guess that explains why it doesnt come with linuxcnc lol
[17:47:26] <maxcnc> Erant: what Linuxcnc versin are you on
[17:47:32] <Erant> Latest release
[17:47:34] <Erant> 2.7?
[17:47:51] <maxcnc> that shoudt work out of the box
[17:47:55] <Erant> There's a little dropdown list in the pncconf that says "Firmware"
[17:48:13] <Erant> And it lists about 5 combos of 7i76 and other boards.
[17:49:35] <DaPeace> maxcnc: do i need to load that flipflop-components?
[17:49:43] <maxcnc> yes
[17:49:52] <maxcnc> and dont forget the servotreads
[17:50:03] <pcw_home> I doubt there is 7I78 support on pncconf
[17:50:29] <maxcnc> loadrt flipflop names=flipflop_resume,flipflop_pause,flipflop_run,flipflop_icon
[17:50:30] <maxcnc> addf flipflop_resume servo-thread
[17:50:32] <maxcnc> addf flipflop_pause servo-thread
[17:50:32] <pcw_home> you are going to have to suart with an example hal file and edit to suit
[17:50:33] <maxcnc> addf flipflop_run servo-thread
[17:50:38] <DaPeace> ok.. i will copy that.. i have powered off the machine already. i will try tomorrow.
[17:51:15] <maxcnc> DaPeace: did you get the last 3 lines from me
[17:51:18] <DaPeace> yes
[17:51:38] <DaPeace> thank you very much. will try that out. didnt know that flipflop-component
[17:51:41] <JT-Shop> _methods, need to chamfer the hole or it leaves a lip but taps nice
[17:52:05] <_methods> yeah taps'll do that
[17:52:12] <maxcnc> DaPeace: go throu the man9 pages
[17:52:29] <_methods> i always chamfer them to help tap on entry anyways
[17:52:37] <DaPeace> maxcnc: xhc-hb04 is your button-pin right?
[17:52:45] <maxcnc> yes
[17:53:04] <DaPeace> ok. thank you will try that out.
[17:53:22] <maxcnc> NP
[17:53:27] <JT-Shop> I tapped air for a few times till I was happy it wouldn't over shoot
[17:53:40] <_methods> yeah good idea
[17:54:15] <maxcnc> DaPeace: my user hal without postgui now has pased the line 200 mark
[17:54:36] <DaPeace> ok.. thats a little little more than mine :-D
[17:54:52] <maxcnc> and i oly got 18buttons in real

[17:56:10] <maxcnc> did you look at the XHC hb04 control ist worth the money
[17:57:55] <DaPeace> i think i will stay with my 9 buttons. i think about getting a small touchscreen
[17:58:08] <DaPeace> gmoccapy is really nice for using it by touchscreen
[17:58:31] <maxcnc> i now even dont need to load the NC code at the PC its all on the pendand from cad2camtomashine all one nc file

[18:09:36] <CaptHindsight> DaPeace: what kind of spindle is that?
[18:09:46] <DaPeace> 1.5kw air cooled chinese one
[18:10:31] <DaPeace> ive upgraded it some weeks ago and i must say it kicks asses compared to the 400w-spindle before
[18:11:17] <maxcnc> seams as a OEM huanyu

[20:50:27] <andypugh> Can anyone think of a cunning way to tell approximately (to within 1mm) where you are on a leadscrew. The motor resolver can get the rest of the accuracy.
[20:51:01] <andypugh> It needs to be available from power-up.
[20:51:27] -!- anomynous_ has quit [Ping timeout: 246 seconds]
[20:51:42] <andypugh> Well, it doesn’t need to do anything, it’s just a “would be nice” as you can’t always run a lathe all the way to home, if there is a big workpiece mounted, for example.

[20:54:06] <cradek> I've got a string potentiometer/encoder (?) in a junk box
[20:54:27] <cradek> it has an auto-retracting piece of wire with a loop on the end
[20:54:34] <cradek> maybe pulls out a foot
[20:55:20] <cradek> approximately like these, http://www.firstmarkcontrols.com/
[20:55:48] <cradek> seems a LOT easier to mount than any kind of linear scale
[20:56:09] <andypugh> I have thought of those, and I have a feeling that you could probably sneak the string inside the ball-screw telescoping spring
[20:56:31] <FinboySlick> andypugh: That story of mel thing you linked me a few days ago actually sounds like it would be the inspiration for TIS-100.
[20:56:34] <cradek> on the other hand, my lathe homes outward and I don't think I've ever found myself stuck
[20:56:46] <cradek> yes that would be a very nice place to put it
[20:57:04] <cradek> oh if it had a tailstock that sure wouldn't work
[20:57:34] <andypugh> My current one sometimes homes into the jaws of rhe 4-jaw, but it’s NEMA 23, so nothing bad happens. The Holbrook is going to have a 1kW servo.

[20:58:20] <cradek> how much travel is it?
[20:58:33] <andypugh> 500mm
[20:58:41] <FinboySlick> andypugh: If you want to go fancy/complicated, you could grab a cheap webcam and a strip of random noise. OpenCV would be able to tell you which part is in front of the camera.
[20:58:49] <cradek> darn, pretty sure that's more than the one I have
[20:59:29] <andypugh> I have thought of a barcode. Something like Renishaw Reolute
[20:59:32] <cradek> but it's just a clockspring and a pulley and that flexy braided steel cable. you could just make one.
[21:00:03] <cradek> heck put a resolver on it, and gear it so you get one turn (or whatever) for full travel
[21:00:08] <andypugh> stainless steel fishing line
[21:00:16] <cradek> yeah
[21:00:23] <andypugh> I do have spare resolvers. Hmmm
[21:00:38] <andypugh> It would need gearing of some sort
[21:00:40] <cradek> and a spare channel to read one?
[21:00:54] <andypugh> Yes, I have 6 channels on the 7i49 and only two axes
[21:00:55] <cradek> yeah certainly needs gearing
[21:01:02] <FinboySlick> andypugh: Does your lathe have a rack?
[21:01:03] <WZL> you want something ready made or a hack?
[21:01:20] <andypugh> Either. An interesting hack would be interesting.

[21:06:25] <bz> it's basically a three-thread cylinder
[21:06:40] <cradek> a custom form tool could do it with a simple rotary table
[21:06:55] <cradek> so could a ball end mill, with more complex gcode
[21:07:00] <bz> yes

[21:08:27] <cradek> yeah there are all sorts of ways to do this, and I don't see how a trunnion table could help with any of them
[21:09:37] <_methods> making the chamber for it would be a whole other animal though
[21:09:49] <cradek> no kidding

[21:13:33] <anomynous> why is high speed steel so high speed. It's slooooow. Carbide is faster.
[21:15:05] <bz> hm
[21:15:16] <bz> i just realized that making the stator's gonna be essentially impossible
[21:15:33] <_methods> will be very difficult
[21:16:04] <_methods> you could make it in 2 halves
[21:16:24] <_methods> but i'm guessing over time that seam would probably be a source of issue
[21:16:42] <_methods> depending on the fluid/solid being pumped
[21:16:43] <bz> the stator is made of rubber
[21:16:59] <bz> so it'd be cast, so as long as the inner piece of the cast is unseamed, we're fine
[21:17:46] <bz> (if that made sense)
[21:18:00] <_methods> you would have to cast it for sure
[21:19:02] <bz> okay but back to my original question: are trunnions a viable way to make dead-center holes?
[21:19:23] <_methods> a trunion table is just a trunion table
[21:19:35] <_methods> has nothing to do with making "dead-center" holes
[21:19:47] <XXCoder> I saw video on lapping
[21:19:52] <XXCoder> it made REAL smooth hole
[21:20:08] <XXCoder> dunno about centering on that too
[21:20:08] <cradek> bz: can you ask your question in a different way? it doesn't make it clear what you are asking.
[21:22:34] <bz> cradek: i'd like to make a motor shaft adapter
[21:23:18] <anomynous> really cocentric center hole is made by machining it during the same clamp in lathe jaws as outside diameter was done, if thats what youre asking. Using a dial gets you close also.
[21:23:20] <bz> cradek: however, the smaller of the lathes has suffered some damage and as a result some centering issues
[21:23:33] <bz> cradek: the smaller of the two lathes we have, that is
[21:23:42] <cradek> what kind of motor shaft adapter?
[21:23:50] <bz> shaft to square drive
[21:23:57] <bz> those square drives are such a pita, seriously
[21:27:06] <anomynous> or... indicate in four jaw chuck. Or, make hole first, clamp from center and mill outside to square by using a rotary table and moving y or x axis only? ;D
[21:33:38] <andypugh> A rotary axis will make the parts just as concentrically as you set them up.
[21:34:38] <bz> andypugh: are you referring to how rigidly the axis is secured to the table?
[21:34:59] <andypugh> I think I could, in principle, make the stator on my lathe: https://www.youtube.com/watch?v=T4q8gCpeY1A
[21:35:13] <andypugh> Just need to add a phase-shift as the Z feeds
[21:36:38] <andypugh> If you are looking for an excuse to buy a rotary table, then of course you need one.

[21:36:57] <MacGalempsy> well, I got 3dacademy.us lol
[21:37:17] <MacGalempsy> flyer is about ready, just need to order up the parts for the first build
[21:39:37] <andypugh> anomynous: Well, yes, but CNC means you can make any size of hex, or do a pentagon.
[21:40:14] <XXCoder> 120 sides
[21:40:18] <anomynous> andypugh, im not getting you. By cutting 1 m/min?
[21:41:44] <andypugh> I have actually used it: Hexagonal hole in the worm, hexagonal collar on the motor shaft, to make things as short as possible: https://picasaweb.google.com/lh/photo/4rkeONHiwTsx23-66qVmjdMTjNZETYmyPJy0liipFm0?feat=directlink
[21:43:15] <andypugh> anomynous: Well, yes, the relatively slow stepper on the X axis combined with the direct-drive headstock does mean that it’s a bit slow.
[21:43:53] <anomynous> if it works and does what you want
[21:43:56] <anomynous> :D
[21:49:05] <anomynous> i cant find a video. It had a lathe "turret" rotating in synch with the spindle, turning polygons
[21:49:07] <anomynous> ;D
[21:49:47] <andypugh> I know the one

[23:43:05] <andypugh> I like to choose roads on the basis of “I wonder what’s down there” so normally run north-up on the GPS so I can tell which direction to go, not what route.
[23:43:51] <andypugh> So, it’s 23:43, do I start the second 2.5 hour toolpath?
[23:44:38] <andypugh> I am going to say “No” I think.
[23:44:39] <cradek> on a friday? perhaps
[23:45:30] <andypugh> I can’t hear it, so I doubt anyone else can. All I will hear will be the neigbouts upstairs TV, likely until 4am.

[23:46:29] <Erant> What do you guys use for simple gcode generation?
[23:46:37] <Erant> The "I need to make a pocket" variety.
[23:47:52] <Erant> I'm using the direct gcode input thingy right now, but it's slow, and the CAM output for the model I'm making is hard to modify (I have no working Z-Axis yet, so I have to do that manually)
[23:51:39] <andypugh> Take a look at “Features”
[23:51:59] <Erant> In AXIS?
[23:52:10] <Erant> Oh
[23:52:12] <Erant> Found it
[23:55:24] <andypugh> sorry, setting up a run. can talk when it is started
[23:59:30] <Erant> Looks pretty straight forward.
