[00:10:28] <furrywolf> grrr. no fit! I bought two pieces of 1/8" flat bar at the local metal supply place. one is .120, the other .130.
[00:11:16] <furrywolf> is this within normal tolerances, or did they sell me crap metal?
[00:11:31] <_methods> well withing normal
[00:12:11] <furrywolf> ten thous is pretty crap variation...
[00:12:34] <_methods> it's hot rolled or cold rolled flat bar?
[00:12:53] <furrywolf> dunno.
[00:12:59] <_methods> lol
[00:13:17] <furrywolf> I asked them for 1/8 by 1 flat bar...
[00:13:37] <_methods> well that's pretty vague
[00:13:48] <_methods> paper or plastic lol
[00:14:04] <Valen> unless you get something marked as "precision" it won't be
[00:14:08] <Valen> it also wont be flat
[00:15:27] -!- tswartz has quit [Read error: Connection reset by peer]
[00:15:43] <furrywolf> it doesn't need to be precision... but it does need to not be substantially oversized.
[00:15:47] <zeeshan|2> is .004 ipr .375" axial doc too aggressive on a .375" roughing cutter?
[00:15:48] <zeeshan|2> in 6061
[00:15:52] <zeeshan|2> 3 flute
[00:16:28] <furrywolf> the tolerances on everything I got are crap, and add up to not fitting.
[00:17:04] <Tom_itx> zeeshan|2 why would it be?
[00:17:15] <zeeshan|2> when will i snap it
[00:17:15] <Tom_itx> ipt or ipr?
[00:17:18] <zeeshan|2> at how much ipt
[00:17:20] <zeeshan|2> ipt
[00:17:23] <furrywolf> the 1.5" by .180 wall square tube is only 1.130 instead of 1.140 id, and the flat bar is .130 instead of .125... the end result is it's .020 from fitting!
[00:17:35] <Tom_itx> zeeshan|2 you will know when you reach the limit
[00:17:39] <zeeshan|2> lol
[00:17:45] <zeeshan|2> i dont wanan break my only 3 flute rougher
[00:17:49] <zeeshan|2> in .375
[00:17:56] <zeeshan|2> like a tard i collected all these huge end mills
[00:18:10] <Tom_itx> should be fine i think
[00:18:11] <zeeshan|2> which are completely useless to me, cause most of the time i either need .25 or .75
[00:18:13] <zeeshan|2> er
[00:18:13] <furrywolf> nothing wrong with collecting tooling. :P

[00:18:23] <zeeshan|2> 1/2 is useless, so is 3/4
[00:18:32] <zeeshan|2> (for all the parts ive done so far)
[00:19:07] <furrywolf> it feels like cold-rolled to me, as it's nice and smooth, but I didn't ask which it was.
[00:20:09] <Tom_itx> zeeshan|2 too big for your mill?
[00:20:13] <zeeshan|2> no
[00:20:17] <zeeshan|2> too big for what im machinin
[00:20:21] <Tom_itx> why are they useless then?

[00:20:41] <zeeshan|2> the only time ive used the 1" cutter was for that throttle body work
[00:21:13] <Tom_itx> those ti parts we ran took a week
[00:21:32] <Tom_itx> 24/7
[00:21:51] <zeeshan|2> hah
[00:22:01] <zeeshan|2> man ive done all this cam tool path
[00:22:04] <zeeshan|2> and i feel like a tard now LOL
[00:22:10] <zeeshan|2> not sure how to fix this
[00:22:19] -!- Akfreak-iPad has quit [Remote host closed the connection]
[00:22:38] <Tom_itx> fix what
[00:22:43] <zeeshan|2> sec

[00:25:08] <zeeshan|2> poor fish
[00:25:25] <zeeshan|2> so thats after im done the tool path
[00:25:32] <zeeshan|2> its a 1.5" block to start with
[00:25:40] <zeeshan|2> im left with .25"
[00:26:21] <zeeshan|2> not sure how to get rid of the excess
[00:26:27] <zeeshan|2> i need to machine the parts individually after this
[00:26:50] <Tom_itx> the bottom is excess?
[00:26:56] <zeeshan|2> the rectangular part yes
[00:27:17] <zeeshan|2> what comes to my mind is bandsaw it
[00:27:23] <Tom_itx> how many you making?
[00:27:27] <zeeshan|2> just 4 for me :)
[00:27:30] <zeeshan|2> those 4 that you see
[00:27:45] <Tom_itx> cut them apart, flip em over and flycut it
[00:27:50] <Tom_itx> shell mill
[00:27:59] <zeeshan|2> how will i hole it
[00:28:01] <zeeshan|2> *hold
[00:28:05] <Tom_itx> you may have to cut some softjaws for that
[00:28:06] <zeeshan|2> would ike to use the vise
[00:28:13] <jdh> make an inverse first
[00:28:18] <Tom_itx> and hold them in the visejaws
[00:28:31] <Tom_itx> the 2 ovals should be the same
[00:28:42] <Tom_itx> the other two are opposite
[00:29:04] <Tom_itx> you don't need the whole profile, just maybe 1/4" of it
[00:29:12] <Tom_itx> on those anyway
[00:29:17] <zeeshan|2> hm
[00:29:21] <Tom_itx> you'll need a little more on the other 2
[00:29:26] <zeeshan|2> if i gotta make vise jaws, i might as well bandsaw it away
[00:29:30] <zeeshan|2> to individual pieces
[00:29:36] <Tom_itx> i would
[00:30:35] <Tom_itx> or grip the end of the top ones and mill em off (not the best idea)
[00:31:12] <Tom_itx> hold them horizontal with a stop and mill em off with a regular EM from the side
[00:31:40] <Tom_itx> all the same thickness you would only need one setup for that
[00:32:16] <Tom_itx> saw off most of the excess then do that
[00:32:27] <Tom_itx> that would be the quickest

[00:34:09] <zeeshan|2> smart man
[00:34:10] <Tom_itx> cut visejaws would be the most secure
[00:34:14] <zeeshan|2> lol
[00:34:20] <zeeshan|2> i didnt think of flipping it sideways
[00:34:41] <Tom_itx> just take small cuts in Y incrementing Z each pass
[00:34:50] <Tom_itx> and step over in X a bit each time
[00:34:55] <Tom_itx> maybe 3 moves in X
[00:35:00] <Tom_itx> for the thickness
[00:35:08] <Tom_itx> that way they probably won't move on ya
[00:36:06] <Tom_itx> you'll get a little more tool deflection doing it that way
[00:36:17] <Tom_itx> i doubt they're shuttle parts though

[00:37:59] <zeeshan|2> :D
[00:38:14] <Tom_itx> put parallels under the part so they're square with the cutter
[00:38:57] <Tom_itx> you could try out your 1.5" roughing cutter that way :D
[00:39:46] <zeeshan|2> haha
[00:41:05] <Tom_itx> on the long parts, put a spacer where the angle is so at least one side will have full contact with the vise

[01:42:00] <furrywolf> one piece of 1/8 was .010 thicker than the other piece of 1/8, one piece of 3/16 was .009 thicker than the other piece. in both cases, the 1" wide bar was the larger one, while the 3/4" wide bar was the thinner one.

[02:07:15] <Stoneanvil> Pretty new here... anyone tried linuxcnc with Warp9's ESS?
[02:09:35] <cradek> Stoneanvil: those aren't made to be compatible with linuxcnc. consider mesa's zillions of options, which are.
[02:09:57] <furrywolf> I'm going to go with "no", since I can't find any mention googling of anyone even starting to write a driver for it.
[02:10:29] <Stoneanvil> yeah... that's why I asked too... can't seem to find anything on google.
[02:10:30] <cradek> mesa has new ethernet devices now, and a huge line of tried-and-true pci interfaces that many use on industrial machines
[02:11:45] <Stoneanvil> I'm going to stick with Mach3 I guess... I have nothing but linux (ubuntu/centos) running here... I guess the only windows (sigh) machine I will have to support will be for Mach3.
[02:12:11] <cradek> why?
[02:12:48] <Stoneanvil> The machine I have is already PMDX-126 with Warp9 ESS
[02:13:29] <cradek> oops
[02:14:02] <furrywolf> you could buy a mesa 7i76e, which should be a pretty easy swap.
[02:14:27] <Stoneanvil> I would rather not swap hardware this early in the build...
[02:14:34] <cradek> http://en.wikipedia.org/wiki/Sunk_costs#Loss_aversion_and_the_sunk_cost_fallacy
[02:15:11] <Stoneanvil> I will VM the windows dedicate it to Mach3... I just don't trust windows for anything that is related to 'real time'.
[02:15:28] <_methods> well don't worry you won't be using real time lol
[02:15:34] <_methods> not with windows
[02:15:52] <Stoneanvil> yeah.. sucks
[02:16:26] <Rab> Stoneanvil, seems like the PMDX-126 will connect straight to a PC parallel port. You could go that route and sell the ESS on eBay. (More likely, keep it around so you have your original system as backup.)
[02:17:38] <Stoneanvil> Funny enough... not one of my machines is old enough to still have a parallel port. :)
[02:17:53] <furrywolf> price is about the same, ess is $180, 7i76e is $199
[02:17:56] <Tom_itx> those can be had pretty cheap
[02:18:02] <Rab> The motion control smarts in the ESS are redundant; it's not needed with LinuxCNC.
[02:18:58] <furrywolf> I need to un-flashcut my sherline one of these days, but as it's a working machine, and I don't have enough money to finish my other machine...
[02:19:04] <Stoneanvil> Yeah.. that is why I was looking into LinuxCNC... it had faster response and direct toolpath motion control.
[02:19:17] <cradek> Stoneanvil: when in doubt just use a pci card
[02:19:44] <Stoneanvil> I might just do that.
[02:21:03] <Tom_itx> check latency on your pc
[02:21:23] <cradek> you can do that by just booting the live image (from dvd or usb)

[02:27:41] <Stoneanvil> Thanks guys... I think I will try both ways and see which one has the best results.
[02:29:58] <_methods> friends dont let friends use mach
[02:30:15] <Stoneanvil> lol
[02:30:17] <cradek> it can make a lot of extra trouble if you try to use only hardware that works with both systems
[02:30:39] <cradek> it's really best to decide before you start buying things (but I see that ship has sailed)
[02:31:20] <Stoneanvil> Yeah... the system came pre-build with PMDX-126, ESS and Spindle Controller.

[14:48:10] <automata_> anyone have an example of pktuart for mesa hostmot2?

[14:48:25] <automata_> using pktuarts with HAL?
[14:49:30] <archivist> automata_, better to ask the real question than who uses x
[14:50:05] <automata_> I want to use pktuarts to communicate with a serial device.
[14:50:08] * jthornton has never heard of it
[14:50:35] <automata_> i want ot make a serial frame with 16 bytes of data and sent it out
[14:50:53] <automata_> and at the same time receive 16 bytes

[14:53:08] <automata_> That time i found something else shiny... i.e., simple uarts which has a 16 byte frame buffer.
[14:53:41] <automata_> I am trying to send a 16 byte frame to a serial device and read 16 bytes frame back from it every 1 ms
[14:54:00] <cradek> why?
[14:54:41] <cradek> (I'm just curious what problem you are solving - I'm unlikely to have your answers)
[14:55:29] <archivist> or it may already be answered if you just say what you are really doing/talking to
[14:55:30] <automata_> trying to make a serial I/O device
[14:55:44] <automata_> and a serial drive
[14:55:49] <automata_> serial controlled drive
[14:56:39] <automata_> With simple uarts, the receive frame gets extra zeroes padded to the received buffer
[14:57:09] <automata_> If the transmitter and receiver are on the same PC + FPGA, then there is no problem.
[14:57:59] <automata_> However, if I put the transmitter and receiver on 2 separate computers, I get receive desynched with multiple padded zeroes
[14:58:20] <automata_> transmit baud rate 1Mbps
[14:58:24] <archivist> use proper handshake and flow control
[14:58:49] <automata_> This is from the 5i24 FPGA
[14:59:06] <automata_> so in general there is no handshaking
[14:59:34] <pcw_home> PktUARTs are designed for time based framing ( you specifiy the idle time for EOF detection in the hardware)
[14:59:54] <automata_> hi PCW
[15:00:04] <automata_> That is what I am looking for...
[15:00:29] <cradek> automata_: thanks for describing the application and problem
[15:00:30] <automata_> bursts receive of 16 byte frames at 1 - 2.5 Mbps
[15:00:57] <pcw_home> time is specified in bit times ( baud rate can be up to ~ 25 Mbits/sec)
[15:01:14] <automata_> cradek: in fact I should be the one thanking all of you for your tireless effort on this project!!
[15:01:34] <automata_> pcw: ok
[15:01:43] <automata_> are there any HAL examples to use it?
[15:01:50] <pcw_home> sending is done by loading the xmit buffer than loading the char count register
[15:02:03] <automata_> or even C code with the hostmot2 driver?
[15:02:10] <pcw_home> there is no hal support currently
[15:02:36] <automata_> how about hostmot2 driver support?
[15:02:48] <automata_> I can build the HAL support
[15:03:03] <pcw_home> We have used it to support multiple distributed Hostmot2-serial remotes
[15:04:54] <automata_> is there any driver support
[15:05:07] <automata_> any C code that I could peruse
[15:06:07] <automata_> how about readimg?
[15:06:12] <automata_> uart read
[15:07:24] <pcw_home> the RX UART collects chars until there is a gap ( >=specified size ) then sets s flag and a char count
[15:07:53] <automata_> keep polling the mode register for a non-zero frame received count
[15:08:18] <automata_> then read the rx byte count for first packet
[15:09:41] <pcw_home> basically yes (the RX count is also in a FIFO so must not use it for polling)

[15:17:09] <pcw_home> HAL doesn't have the data types to make this easy so probabl any protocol/data stuff needs to be buried in a component anyway
[15:17:09] <automata_> on loding this in 5i24 do I have to specify a config parameter during loadrt hm2_pci ?
[15:17:19] <automata_> agreed

[15:17:44] -!- SB_ has quit [Ping timeout: 245 seconds]
[15:18:03] <pcw_home> no there is no support so you would have to set it up by hand (perhaps in a component)

[15:18:41] <automata_> so I'll make a new component pktuart_test.comp
[15:19:19] <automata_> and do the write and read asap and report the results.

[15:23:09] <automata_> that also could be useful
[15:24:04] <automata_> I also wanted to pick your brain on why my 16 byte protocol for receiving uart packets fails
[15:24:08] <pcw_home> without low level driver support you need to setup the altsrc register to route the TXData and TXEnable
[15:24:10] <pcw_home> to the proper GPIO pins
[15:24:20] <automata_> ok
[15:24:59] <automata_> altsrc?

[15:26:50] <automata_> PIN_pktuarttest_72.vhd file
[15:27:31] <automata_> i.e., setup the PinDesc as: IOPortTag & x"00" & PktUARTRTag & PktURDataPin, -- I/O 00
[15:27:46] <automata_> and for Tx: IOPortTag & x"00" & PktUARTTTag & PktUTDataPin, -- I/O 04
[15:27:50] <automata_> is that right?
[15:28:44] <automata_> setup the second function and second pin right?

[17:45:24] <Verdi> hey. i've got a system with a custom EMC2/linuxcnc from a manufacturer, that unfortunately comes with a way outdated kernel. I've seen that emc2 depends on the RTAI package which limits the range of available kernels. Is it a problem to use RTAI-4.1 instead of RTAI-3.8.1, or is that a major operation?
[17:49:45] <cpresser> Verdi: it is a major task to change the kernel for a RTAI system. i recommend a backup
[17:50:10] <cpresser> Verdi: unless there are good reasons live with the old kernel
[17:52:00] <Verdi> cpresser: there unfortunetly is a good reason, as the touchscreen monitor we have attached is not supported with the older kernel
[17:52:44] <Verdi> i believe i can compile a kernel with RTAI patches, but i'm quite unsure if linuxcnc will play with the newer version without an update
[17:53:43] <Tom_itx> pcw_home would it do any good to place a phone order or do i need to wait for you to update the webpage?
[17:58:09] <cpresser> Verdi: you might need to recompile linuxcnc components since they are loaded as kernel modules
[17:58:30] <cpresser> Verdi: check if its easier to backport the touchscreen driver
[17:58:46] <Verdi> cpresser: that's kinda what i was afraid of. thanks
[17:59:00] <skunkworks> Verdi, what oem?
[17:59:52] <Verdi> skunkworks: it's a Tormach mill, and while they praise their "new" software as so much better, it comes, completely alien to me with a ubuntu 10.04LTS
[18:01:05] <Verdi> and while the linuxcnc they hacked together granted works better than mach3 ever did it breaks my touchscreen, which is kind of annoying

[18:05:24] <skunkworks> Verdi, have you called tormach to see if maybe they have others with your touch screen? (work around)?
[18:06:29] <cradek> you can possibly build your touchscreen driver against the kernel they are distributing
[18:06:34] <Verdi> skunkworks: of course did. all they offer is that they now sell a different touchscreen which works, however they admitted at the phone that they had a number of issues and many complaints with it
[18:06:58] <Verdi> cradek: the touchscreen support was added natively
[18:07:28] <cradek> be aware that if you use a different kernel you will have to also build rtai and then linuxcnc, and you will be unable to use their binary distribution
[18:08:16] <Verdi> cradek: i got as much, so that's probably not an option. i'm no stranger to building packages, but since i don't exactly know what customizations these guys did it's probably a fools errand
[18:08:20] <cradek> ... which is fine, as they will provide you with complete/corresponding source, but it's work you will have to do
[18:08:45] <cradek> well you can certainly get the source with all their customizations
[18:09:29] <cradek> it's unfortunate they are using an EOL'd distribution for their new product :-/
[18:10:07] <Verdi> it is
[18:11:58] <Verdi> i mean there's little reason it wouldn't run on a more modern system, but i guess they don't want to invest the time to port things
[18:12:36] <cradek> I would be surprised if there were any problem moving to debian wheezy, since the linuxcnc team has supported that for some time now
[18:14:10] <Verdi> obviously just doing an end user dist upgrade does not work, but it's a bit dissapointing to "upgrade" from an old system to a new, just to get another old system with a shiny cover
[18:14:11] <cradek> wish touchscreen manufacturers would stop making new protocols. it's insane.
[18:14:42] <Verdi> the monitor isn't all that new
[18:16:37] <Verdi> it's an iiyama t2250, which works perfectly on ubuntu 12LTS, just not on 10.04LTS
[18:18:06] <automata_> hi pcw
[18:18:26] <automata_> hi andypugh
[18:18:34] <andypugh> Hi
[18:18:49] <automata_> I was having trouble with uart receive
[18:18:53] <cradek> Verdi: pardon my curiousity - is this monitor something that came with the tormach mill you bought from tormach?
[18:18:59] <automata_> I am using your component uart.c
[18:19:11] <automata_> for the hostmot2 driver
[18:19:13] <skunkworks> Verdi,
http://ubuntuforums.org/showthread.php?t=1469326
[18:19:22] <Verdi> cradek: it's something we bought later on
[18:19:42] <cradek> Verdi: but from tormach, or yourselves?
[18:19:43] <automata_> I am trying to receive 16 bytes every 1ms at 1Mbits/sec
[18:19:54] <Verdi> cradek: ourselves. back then they didn't offer a touchscreen
[18:20:11] <Verdi> skunkworks: thanks i'll try that
[18:20:17] <automata_> i have put a uart read in a 1 ms thread.
[18:20:22] <cradek> ah I see, thanks
[18:20:47] <cradek> Verdi: it would be interesting to boot the wheezy+linuxcnc live cd and see if your screen works
[18:20:59] <automata_> I keep seeing byte overflows
[18:21:06] <andypugh> automata_: That should work, but keeping track of which byte of the two you just read is always fun
[18:21:20] <Verdi> cradek: i can try that too, but then the mill is probably not set up
[18:21:27] <cradek> sure I understand
[18:21:33] <automata_> the data I read is sometimes shifted
[18:21:43] <automata_> by a few bytes
[18:21:44] <andypugh> automata_: Your .copm needs to always read all the data that is there.
[18:22:10] <automata_> In the comp, I am reading only when there is 16 data available in the FIFO and then I read all the data
[18:22:30] <andypugh> I can’t remember how big the FIFO is.
[18:22:40] <automata_> I think it is 16 bytes
[18:23:08] <andypugh> (If I was doing the UART driver again I would do it differently, more like the BiSS and friends)
[18:23:20] <automata_> most of the times I can read all 16 bytes... just once every few 10's of msec i get shifted data
[18:23:37] <andypugh> I would suggest reading all the data every time, and only interpreting it when you have a full set.
[18:23:44] <automata_> ok
[18:23:51] <automata_> I will try that...
[18:24:06] <andypugh> It only takes a slight clock shift to get 17 bytes between reads
[18:24:23] <automata_> yup...
[18:25:42] -!- per_sonne has quit [Quit: Be back later ...]
[18:26:09] <automata_> so make a buffer in uart.comp and every 1ms (when the read function is called) read all the available bytes
[18:26:51] <andypugh> Yes
[18:26:51] -!- sumpfralle has quit [Ping timeout: 264 seconds]
[18:27:22] <automata_> then the mesa_uart.comp will only request 16 bytes at a time..
[18:28:23] <andypugh> Even then, if the transmitting thing sends 16 bytes per mS you might over-fill the buffer. You might need to shorten the servo-thread time to make sure that there are never more than 16 bytes per servo thread.
[18:28:24] <automata_> in the uart.c function, we are reading 4 bytes at a time. is that necessary?
[18:28:51] <andypugh> I am afraid I can’t remember.
[18:28:59] <automata_> ok
[18:29:00] <andypugh> It’s been rather a long time.
[18:29:13] <andypugh> Have you looked at the regmap file?
[18:29:23] <automata_> yup... read it in and out...
[18:29:36] <automata_> we can read 4, 3, 2, and 1 bytes
[18:29:38] <andypugh> OK, that’s pretty much all the docs there are
[18:30:09] <automata_> ok
[18:30:40] <andypugh> If you prefer to re-write the UART driver C code just for your application, and recompile the whole of LinuxCNC that might be a better solution.
[18:30:54] <automata_> i am trying that too...
[18:31:15] <andypugh> I am not very happy with the hm2_uart driver just passing a handle idea.
[18:31:19] <automata_> I am also trying to use pktuarts but that is also not going anywhere...
[18:32:10] <andypugh> But at the time the uart driver was added there wasn’t the code for creating arbitrary HAL pins at load time that Smart-Serial made necessary.
[18:33:39] <andypugh> BiSS / SPI might work better if your sender is under your control. You can send longer than 8-bit data then.

[21:12:23] <Tom_itx> there may be better daughter cards for that but i wanted the 7i47 for differential io
[21:12:43] <membiblio> @skunksleep How does it know if it is on path?
[21:13:21] <andypugh> It reads back the current step count before sending the new velocity

[21:22:43] <automata__> Finally got plain vanilla uarts working
[21:22:58] <automata__> pktuarts still not working though
[21:23:07] <automata__> thanks andypugh
[21:23:30] <andypugh> I wasn’t even aware of pktuarts
[21:23:39] <automata__> i had to get the read and write in 2 different threads...and read needs to work 10x faster than write
[21:23:52] <andypugh> Curious
[21:24:05] <automata__> sending 16 bytes of data
[21:24:18] <automata__> and expecting to receive 16 bytes of data after the send
[21:24:50] <automata__> the 16 byte read used to always overflow or miss something
[21:25:14] <automata__> so finally separated the read and write threads and made the read thread run at 0.1ms
[21:25:23] <automata__> and write thread still at 1ms
[21:26:03] <automata__> now it works...
[21:26:09] -!- XXCoder has quit [Read error: Connection reset by peer]
[21:26:41] <automata__> if i take the read thread at 2x to 5x write thread frequency, reading skips
[21:27:06] -!- automata_ has quit [Ping timeout: 272 seconds]
[21:27:29] <automata__> error rate comes down exponentially wrt the frequence of read v/s write
[21:30:40] <Valen> moooornin all

[22:43:22] <alex4nder> so, I picked up a mesa 7i76E, and I saw some mention of DPLL support
[22:43:39] <alex4nder> can anyone hook me up with some specifics of how DPLL works/helps things?
[22:43:57] <alex4nder> (i.e. in a practical setting; I know what a PLL is)

[22:50:45] <micges> alex4nder: you must just choose dpll timer and set it in hal to *.stepgen.timer-number
[22:51:22] <micges> rest is done automagically in hostmot2 driver when it detects dpll firmware
[22:51:36] <alex4nder> cool
[22:52:16] <micges> of course you need to setup dpll first, can't tell if default data are ok
