[14:55:32] <Jymmm> Ir's been so long, I can't even remember how to solve that and I have the answer too!

[14:56:46] <r00t4rd3d> do you weight and measure them?
[14:57:36] <r00t4rd3d> and compare those numbers to intake

[15:00:27] <Jymmm> Is that: x-2/-2 ?
[15:00:43] <Jymmm> err x-4/-2
[15:02:02] <R2E4_> 1
[15:02:52] <Jymmm> R2E4_: ?
[15:03:39] <R2E4_> x=4 same as 2=4 4/4 =1
[15:03:45] <R2E4_> I suck at math

[15:09:15] <R2E4_> x-4over2-4
[15:09:50] <Jymmm> R2E4_: and then?
[15:10:17] <pcw_home> I may have the order of operations wrong so X-6 is correct
[15:10:44] <Jymmm> pcw_home: Isn't the answer: 1/6x^2

[15:38:54] <Jymmm> err...
[15:39:18] <Jymmm> The solution is: (1/6)x^2 - (3/2)x + 10/3
[15:42:24] <R2E4_> huh?

[17:44:33] <__Gabe__> it works incredibly well even if your using time.sleep() in python
[17:45:03] <__Gabe__> you just map your python program to its pid pin, so it sends the signal to the write process

[18:21:29] <IchGuckLive> what is your profession milling lathe plasma laser 3D printing ....
[18:21:47] <pcw_home> Yes the hole will be elongated so the projection of the hole is a circle
[18:22:22] <IchGuckLive> and the movement is not a strait
[18:22:35] <andypugh> It is a function of the diameter of the two pipes
[18:22:38] <IchGuckLive> (line)
[18:23:01] <IchGuckLive> diameter are most Equal
[18:23:12] -!- b_b has quit [Changing host]
[18:23:21] <andypugh> Might as well solve for the general case
[18:23:57] <andypugh> The equation in xy of the top pipe is x^2 + y^2 = r1^2
[18:23:57] <IchGuckLive> someone has inventor at hand to get a metall sheet part to strait flat
[18:24:12] <andypugh> We can leave X alone.
[18:24:46] <andypugh> The Y displacement can be transformed into an angle, it's pretty easy I think.
[18:24:56] <IchGuckLive> yes
[18:25:50] <andypugh> Look along the axis of the second pipe. You need the angle at which the distance to the centre is the Y above
[18:26:33] <andypugh> y = r2 sin theta
[18:26:42] <IchGuckLive> unwinding
[18:27:05] <andypugh> so your shape is the locus of points x^2 + (r2 sin theta)^2 = r1^2
[18:27:16] -!- fomox [fomox!~chatzilla@] has joined #linuxcnc
[18:27:56] <andypugh> But actually it is going to be more convenient to follow a top-pipe angle from 0 to 360, calculating x and theta for each point.
[18:28:27] <andypugh> x = r1 sin A, y = r2 cos A.
[18:28:38] <IchGuckLive> on etch deg is enoph for low R
[18:29:42] <andypugh> r2 cosA = r1 sinB, or B = arcsin(r2 cosA)/r1
[18:31:37] <andypugh> so, for A = 0 to 360 X = r1 sinA, B = arcsin(r2 cosA)/r1
[18:32:32] <andypugh> 1821 to 1831. You owe me £8.33 consultancy :-)
[18:33:46] <andypugh> I wonder if it is true?
[18:35:32] <andypugh> For r1 > r2 it should make one half of the "mouth" shape too.

[19:55:52] <c60> well I've setup everything according to that wiki, and I can see the outputs in hal meter and have changed the values to the correct names, but it's not jogging.
[19:56:09] <c60> so I'm thinking I must be missing something, I'm using the exact same joysti
[19:56:17] <JT-Shop> are you pressing the enable button?
[19:56:26] <c60> you mean one of the number buttons?
[19:56:34] <c60> or is there another enable?
[19:56:38] <JT-Shop> yes, if you did the 3 speed one
[19:56:47] <JT-Shop> press a speed first then move the joystick
[19:56:56] <c60> yup, still not working though
[19:57:40] <JT-Shop> open up Machine > Show Hal Configuration and watch the pins as you move the joystick
[19:59:00] <c60> yup, that all works, I have input.0.abs-x-position reporting correct and all the other pins/buttons
[20:00:00] <c60> which I'm using input.0.abs-y-position and input.0.abs-rz-position
[20:00:58] <JT-Shop> and you have the manual control tab selected?

[20:02:40] <andypugh> And are you remembering to press one of the back buttons?
[20:02:41] <JT-Shop> put halui.jog-speed and halui.0.analog or 1 or 2 and see that they show a change

[20:03:20] <JT-Shop> hi andypugh
[20:03:34] <andypugh> Hi
[20:03:39] <c60> so when I watch halui.jog-speed I see nothing
[20:03:44] <c60> or 0 rather
[20:04:14] <andypugh> I am guessing that either you are not pressing the back buttons, or you didn't addf the mux4
[20:04:40] <andypugh> Or you haven't turned the joypad on (mine only workw with the LED on)

[20:05:55] <andypugh> You seem to lack the net joy-speed-final halui.jog-speed <= mux4.0.out line then?
[20:06:12] <L84Supper> which open CAM application has the most features and best support?
[20:06:45] <andypugh> L84Supper: Are there enough for there to be a contest?
[20:06:50] <c60> I have net joy-speed-final halui.jog-speed <= mux40.0 out in my postgui.hal
[20:06:57] <L84Supper> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Cam
[20:07:23] <andypugh> So you should have a joy-speed-final signal then (it's under signals, not pins)

[20:12:18] <c60> JT-Shop: I do have the addf or2.0 servo-thread there too, do I not need the loadrt
[20:12:54] <JT-Shop> please read http://www.linuxcnc.org/docs/html/hal/basic_hal.html
[20:13:29] <JT-Shop> also ignore my typo about addf and loadrt
[20:13:48] <JT-Shop> you have or20 and it should be or2.0
[20:14:17] <JT-Shop> the point zero is the instance number like .0 next one is .1 etc
[20:14:29] <c60> ah yes I see I added an extra zero to a bunch of things, I'll fix and see what happens.
[20:16:35] <c60> does the machine need to be homed for this work, or should it work before I home too

[20:21:00] <c60> will closing and restarting axis reload all files, or is there a command I have to issue
[20:21:14] <andypugh> Closing and restarting axis will do it
[20:23:34] <andypugh> I don't quite understand that file, it seems over-complicated. I don't use the "or2" functions. Top button slow, bottom button faster, both buttons really fast.
[20:23:36] <c60> I still don't see a joy-speed-final under signals though.
[20:24:34] <andypugh> Exit axis, start linuxcnc from the command line (command is "linuxcnc") . You will probably see the error reported in the console
[20:24:43] <JT-Shop> pastebin your postgui.hal file again
[20:24:52] <andypugh> he just did
[20:25:12] <JT-Shop> oh missed it
[20:25:51] <c60> No errors on the console, :(
[20:25:56] <andypugh> Do you see the exact button names?
[20:25:57] <c60> usually that's a good thing.

[20:28:39] <c60> nope,

[20:33:49] <andypugh> This also explains why it was starting with the typos, the file wasn't even being read
[20:34:14] <c60> well I added the stuff in postgui.hal to the custom_postgui.hal since I had some stuff for the touchoff routine in there.

[21:34:21] <tjtr33> works great, 63nS precision but bottom end is 1.8uS :(
[21:36:03] <JesusAlos> there are a way to create a internal variable for general use in Hal?

[21:43:30] <tjtr33> andypugh, nice encoder, is it thru hole? and i used C to setup Timer0 in CTC mode. as close to ASM as i could get in IDE. will try in-line
[21:44:12] <tjtr33> Toy? acronym newto me
[21:44:34] <andypugh> Yes, it's a through-hole one. Not big enough for my application (lathe spindle) but it means it can sit on its own bearings with belt tension taken externally.
[21:44:44] <andypugh> "Toy" was a typo.
[21:45:08] <tjtr33> nice buy
[21:45:15] <andypugh> tjtr33: Perhaps make the timer retriggerable?
[21:45:50] <tjtr33> need oneshots triggered by process
[21:46:18] <tjtr33> edm pulse ( yes of course its for edm, thats what i do :)
[21:46:21] <andypugh> I think you can trigger them on GPIO entirely inside the AVR?

[21:58:17] <Tom_itx> i need to fix my pendant spindle logic
[21:58:30] <Tom_itx> been too lazy to get into it though
[21:58:53] <andypugh> JesusAlos: Can you describe in more detail?
[21:59:00] <Tom_itx> you shouldn't be able to 'run' unless the spindle is back on
[21:59:31] <Tom_itx> and you shouldn't be able to turn it off unless it's paused
[21:59:41] <andypugh> JesusAlos: I think you need "lut5" http://www.linuxcnc.org/docs/html/man/man9/lut5.9.html
[22:00:22] <andypugh> The documentation is not very clear :-)
[22:00:22] <__Gabe__> don't you just love hal!
[22:00:30] <__Gabe__> always had what you need
[22:00:35] <__Gabe__> has*
[22:01:30] <andypugh> write out the truth-table as shown, then write the rquired output in the end column, then read it as a binary number reading upwards.
[22:02:29] <andypugh> Tom_itx: lut5 is probably what you want too. Assign the input bits to interlocks and buttons, then write a 1 if you want spindle on, and a 0 if you want spindle-off in the last column, and then convert from binary readin upwards.
[22:02:29] <__Gabe__> why use google... when you can just ask Andy the living hal component encyclopedia

[22:26:24] <andypugh> I think G33.1 is the usual code.
[22:26:38] <Tom_itx> does it cancel G96?
