[00:30:22] <aitalmac_> I have some questions on 5 axis machining
[00:30:59] <aitalmac_> WHy i cannot touch off with the 5 axis simultion in EMC?
[00:31:38] <aitalmac_> what kind of file you need to run the 3D simulation?
[00:31:50] <aitalmac_> where are stored the distances between joints?
[02:01:46] <alex_joni> aitalmac_: you need to construct a simulation to emulate your machine
[02:02:00] <alex_joni> there are some already done, but surely not for your specific machine
[02:02:14] <alex_joni> look at the sample configs (5axis sim and such)
[02:02:22] <aitalmac_> I'm looking
[02:02:32] <alex_joni> the program for simulation is called vismach
[02:02:51] <aitalmac_> How do i compile the kinematics?
[02:03:11] <alex_joni> http://git.linuxcnc.org/gitweb?p=emc2.git;a=blob;f=configs/5axis/5axis_sim.hal;h=cec6641459a2a4fe9427f37c8790b5bd5dbf01e7;hb=HEAD
[02:03:24] <alex_joni> there you see a reference to 'loadusr -W 5axisgui'
[02:03:32] <alex_joni> 5axisgui is the simulation program
[02:03:50] <alex_joni> aitalmac_: that is a too generic question to answer
[02:05:14] <aitalmac_> Just help me out for a second, right now i'm working on the 5axis files that you have direct me to
[02:05:49] <aitalmac_> i have seen that when i rotate U to 90, joint 1 and 2 go to position 250
[02:06:02] <aitalmac_> now if i wanted them to go for exaple to 500 500
[02:06:23] <aitalmac_> I have to change the kinematics module?
[02:07:05] <aitalmac_> the kinematics module is 5axiskins.c
[02:07:15] <alex_joni> right
[02:07:26] <alex_joni> the 5axiskins file is specific for a certain machine
[02:07:33] <alex_joni> it won't work on any 5 axis machines
[02:07:40] <aitalmac_> but after i modify that i have to recompile it right?
[02:08:03] <aitalmac_> just changing the code will not do anything, i have to recompile the whole EMC code?
[02:08:14] <aitalmac_> or can i just recompile that specific file?
[02:08:47] <aitalmac_> http://www.cyberciti.biz/tips/compiling-linux-kernel-module.html
[02:08:50] <aitalmac_> i was looking at this
[02:09:03] <aitalmac_> will it work?
[02:09:06] <aitalmac_> i have my doubts
[02:09:35] <alex_joni> http://www.youtube.com/watch?v=fWKYQUj5AOs&feature=mfu_in_order&list=UL
[02:09:57] <aitalmac_> In china Youtube is blocked
[02:09:59] <alex_joni> aitalmac_: there is no reason to recompile the linux kernel, or a module
[02:10:18] <alex_joni> you can compile a module (after you modified it) with comp
[02:10:43] <alex_joni> comp http://linuxcnc.org/docs/html/hal_comp.html#sec:Compiling-realtime-components
[02:11:09] <alex_joni> but you need to have the devel package of emc2 installed (I think emc2-devel)
[02:12:24] <aitalmac_> ok i'll look into that, only one question more
[02:13:19] <aitalmac_> How tool Z compensation works on this 5 axis machine, and why when i move the joint manually i cannot go in MDI mode no more
[02:13:27] <aitalmac_> two questions
[02:13:42] <alex_joni> tool Z compensation should be always along Z
[02:13:49] <alex_joni> how that points depends on the kinematics
[02:13:57] <alex_joni> for a simple machine Z = joint 2
[02:14:06] <alex_joni> so tool compensation is done only from motor 2
[02:14:20] <aitalmac_> Oh so right now in the machine the tool comp is on W
[02:14:28] <alex_joni> that's better
[02:14:31] <aitalmac_> the W axis
[02:14:43] <alex_joni> yes, the W axis isn't fixed in space (as is Z)
[02:14:56] <alex_joni> the W axis moves along with the head, because of kinematics
[02:15:01] <aitalmac_> I got it now
[02:15:39] <alex_joni> second question: if you have a kinematics transformation, the machine needs to know where it is, when doing the moves from joint to world and back
[02:15:54] <aitalmac_> Also why i cannot touch off the axis with touch off button?
[02:15:58] <alex_joni> only KINEMATICS_BOTH can move in joint space, and then switch to world and back
[02:16:04] <aitalmac_> I can do it only in MDI mode?
[02:16:06] <alex_joni> aitalmac_: that I don't know
[02:17:34] <aitalmac_> So i can only move the machine in MDI
[02:17:58] <alex_joni> the problem is that in emc2 things aren't done right for non trivkins
[02:18:08] <alex_joni> there is a branch (called ja3) which does things a bit better
[02:18:09] <aitalmac_> If i move joint manually i'll have to restart EMC
[02:18:16] <alex_joni> no, you need to rehome
[02:18:26] <alex_joni> then you should be able to switch back to world
[02:18:30] <aitalmac_> rehome does not work for me
[02:18:38] <aitalmac_> at least in the simulation
[02:18:39] <alex_joni> or you fix the kinematics
[02:19:03] <alex_joni> so it's kinematics_both (meaning you can switch from world to joint and back at any time)
[02:19:12] <alex_joni> but why do you need joint movements?
[02:20:03] <aitalmac_> i think they are only used for manual positioning, or maybe to go out of the piece if something happens
[02:20:20] <aitalmac_> but you can still use MDI for that
[02:20:30] <aitalmac_> i guess it's not a big issue
[02:22:32] <aitalmac_> emc ja3 is the one to work on if i want to develop a 5 axis?
[02:22:47] <alex_joni> probably so
[02:23:02] <alex_joni> but it depends on the machine, and how much time you want to invest in it
[02:26:58] <aitalmac_> Well the machine would be a 5 axis machine that can work sculptures on stones
[02:28:43] <aitalmac_> time is not a problem
[02:28:56] <aitalmac_> where can i find the ja3 branch?
[02:46:32] <alex_joni> http://git.linuxcnc.org/gitweb?p=emc2.git;a=tree;h=refs/heads/joints_axes3;hb=refs/heads/joints_axes3
[05:42:33] <Mjolinor> witha manual rev counter on my spindle I have hte "spindle speed" display in EMC correct
[05:42:53] <Mjolinor> but when I use the M4 S"speed in RPM" gcode commands the revs are way off
[05:43:29] <Mjolinor> if I enter S1000 the spinodle goes at 3000, S10,000 gives me 12,000 and S17000 gives me 14,000
[05:43:39] <Mjolinor> so its non linear and buggered
[05:43:55] <Mjolinor> suggestions as to where to rectify this problem ?
[05:59:18] <awallin> how are you displaying spindle-speed in EMC ?
[05:59:52] <Mjolinor> with the pyvcp thing
[06:00:19] <awallin> and are you dividing/multiplying that value?
[06:00:30] <Mjolinor> by 60
[06:00:45] <Mjolinor> to get rpm as oppposed to rps
[06:00:56] <Mjolinor> and by 7 to get it correct according to pulses per rev
[06:02:07] <Mjolinor> encoder.o.postitoin.scale is set to 7 and scale.0.gain is set to 60
[06:03:22] <awallin> put a halmeter on motion.spindle-speed-out and see what that is
[06:04:24] <Mjolinor> good thinking
[06:04:31] <Mjolinor> forgot about the scope in there
[08:28:13] <awallin> http://hackaday.com/2012/01/19/building-a-variable-frequency-drive-for-a-three-phase-motor/
[09:13:23] <Ekkeri> hhm, I tried ues stepconf but "test axis" didn't do anything, any idea where/how to start debugging? driver is connectec via parallel port, charge pump is disabled and driver says it's enabled and running
[09:14:29] <Ekkeri> maybe it's wiring issue
[09:15:27] <Ekkeri> driver works with usb
[09:17:16] <Ekkeri> I think I will do somekind of adapter so I can connect those parallel port pins to scope so I can be sure it works up to that point
[09:19:58] <awallin> usb pp is not a good idea...
[09:20:22] <Ekkeri> it's not usb
[09:22:30] <JT-Shop> did you see the parallel port tester on the forum
[09:23:35] <Ekkeri> nope, haven't paid that much attention to this parallel port thing :)
[09:23:53] <JT-Shop> http://linuxcnc.org/index.php/english/component/kunena/?func=view&catid=18&id=4743
[09:25:18] <Ekkeri> thanks, I will try it
[09:32:25] <Ekkeri> I'm getting 3.3V out, at pin 1 at least
[09:41:26] <Ekkeri> same with all other outputs and inputs works too, so that shouldn't be a problem
[09:42:44] <Ekkeri> do I need to do something else than launch my setup from shortcut that stepconf made?
[09:43:06] <JT-Shop> nope
[09:43:54] <Mjolinor> if "test axis" didn't do anyhting then I would start there really not go further until that is sorted
[09:44:46] <Ekkeri> so machine power on from emc and then it should output steps to parport?
[09:45:14] <Mjolinor> provided your emergency stop input is OK
[09:45:22] <Mjolinor> if it is defined
[09:45:34] <Ekkeri> I don't have it
[09:45:46] <Mjolinor> dont bother with EMC, do it with stepconf tes axis option
[09:45:51] <Ekkeri> ok, I will get my scope
[09:45:53] <Mjolinor> test axis
[09:46:27] <Ekkeri> why?
[09:46:59] <Mjolinor> because if it doesnt work in stepconf it is not going to work in ENC and debugging that in EMC is a whole lot harder
[09:47:17] <Mjolinor> the parallel port tester that is ^^^^ up there is very good
[09:47:39] <Ekkeri> I didn't like it :)
[09:48:39] <Ekkeri> but all pins worked, 3 hands would have been handy since I had to hold those buttons while measuring with volt meter
[09:50:17] <Mjolinor> there is a really good invention called a "crocodile clip" that assits in such diffcult situations
[09:50:33] <Mjolinor> :)
[10:25:02] <Ekkeri> ok, I'm getting pulses from parport, maybe it's timing issue then, not sure what type of pulses my driver need :)
[10:25:27] <Mjolinor> what pins are you uysing?
[10:26:11] <Ekkeri> 2&3 for X step/dir
[10:26:22] <Mjolinor> ok
[10:26:58] <Mjolinor> reason for asking is that I have seen parallel prots wehre pin 1 doesnt behave sensibly sometimes but if oyu are using 2 adn 3 that isn't your porblem
[10:27:20] <Mjolinor> what is your driver?
[10:27:29] <Ekkeri> 1 is charge pump, but I can skip it
[10:27:51] <Ekkeri> http://www.granitedevices.fi/index.php?q=servo-drive-vsd-e
[10:28:51] <Ekkeri> http://www.granitedevices.fi/index.php?q=vsd-e-breakout with this
[10:29:47] <Mjolinor> so the driver no doubt needs to be configured for strep direction rather than its other input methods
[10:29:54] <Mjolinor> complicated thing that :)
[10:30:12] <Ekkeri> yup, done that
[10:30:40] <Ekkeri> maybe I will recheck it after I have measured enough :)
[10:31:08] <Mjolinor> well it seems to me that if oyu have step / dir coming out hte parallel port for sure then the problem lies elsewhere :)
[10:31:35] <Mjolinor> did you change the vaules in stepconf on the first page?
[10:31:36] <Ekkeri> yup, but charge pump doesn't seems to work with that "axis test"
[10:31:58] <Mjolinor> the defaults for step pulse I tinbk were 5000 ns
[10:32:07] <Mjolinor> that is very fast
[10:32:16] <Mjolinor> maybe its too fast for your driver
[10:32:22] <Mjolinor> if oyu left it as it was that is
[10:32:24] <Ekkeri> I updated those to 20000ns few minutes ago
[10:32:39] <Ekkeri> and now there are longer pulses in scope window :)
[10:32:54] <Mjolinor> my stepper driver needed 30,000 minimum in there
[10:33:28] <IchGucksLive> Hi all
[10:36:14] <IchGucksLive> DC servo on Linuxcnc http://www.youtube.com/watch?feature=endscreen
[10:36:34] <Ekkeri> doesn't work with longer pulses either, I will check those driver confs
[10:36:38] <IchGucksLive> someone has a sketch to connect this to the PC
[10:36:40] <Mjolinor> 150 ns minimum
[10:36:58] <Mjolinor> so you are well over that :)
[10:37:12] <Ekkeri> yup, at 30000ns now :)
[10:38:25] <Mjolinor> nope, wrong value thjat, 150 ns is minimum from direction to step inputs
[10:39:47] <Mjolinor> 125 ns minimum hold time :) that is even faster :o
[10:45:44] <Ekkeri> wow.
[10:45:49] <Ekkeri> it's working now
[10:45:58] <Mjolinor> :o
[10:46:10] <Mjolinor> and all you changed was hte step length?
[10:46:23] <Ekkeri> so it was config issue, nice debugging effort thou :)
[10:46:55] <Ekkeri> Mjolinor, nope, I think those was still in SPI mode although I changed it already to step/dir
[10:47:04] <Mjolinor> ok
[10:47:08] <Ekkeri> those.. it.. only X for now
[10:47:13] <Mjolinor> good result anyway :)
[10:47:22] <Ekkeri> yup, I'm happy now :)
[10:48:32] <Ekkeri> now I will try that stepconf again :P
[10:49:16] <Ekkeri> so 200ns to all should be enough? 30000ns in step anda 1000000ns in dir now :P
[10:51:22] <Ekkeri> no idea about those max. vel/acc
[10:51:54] <Mjolinor> best way is to test the axis
[10:51:59] <Mjolinor> and change them
[10:52:06] <Mjolinor> until it doesnt work anymore
[10:52:11] <Ekkeri> :)
[10:52:33] <Mjolinor> but looking at that spec I reckon EMC will run out of go before your driver does :)
[10:53:07] <Ekkeri> I will change to PWM after I have tested these with parport
[10:53:18] <Ekkeri> I have some Mesa hardware
[10:58:10] <Ekkeri> but I'm ok with this first servo, have to do some soldering next, second one is missing encoder wires, maybe I have X&Y workng at the end of this week :)
[11:51:22] <mrsun> Ekkeri, had problems with that with my bob and my drivers that i needed extremly high step and dir pulses, turned out the bob shorted the outputs to gnd, so i had to put +5V directly into the drives, take the - led to the bob and let it short to gnd
[11:51:47] <mrsun> so when they were not active it gave +5V on the - side of the inputs also
[11:51:53] <mrsun> when active it shorted to gnd
[11:52:21] <mrsun> when i had problems i put the output into the + side on the drive and the - side to gnd directly, worked but very bandly and needed extremly high delays
[11:53:09] <mrsun> oh but that was quite a special bob :P
[12:24:53] <Mjolinor> any engineering types can tell me how big to make the hole for a roller bearing that is 30 mm OD
[12:24:58] <Mjolinor> for an interference fit
[12:25:22] <Mjolinor> I used ot use a zeus chart for such things but haven';t done it 40 years
[12:26:46] <Mjolinor> there are seom pretty damn compplicated equations no the net for it :)

[13:14:02] <DaViruz> anyone know if it's possible to use the mesa remote i/o cards for emc with hostmot?
[13:14:10] <DaViruz> together with an fpga card ofcourse
[13:14:50] <andypugh> Which card?
[13:15:22] <DaViruz> 7I66
[13:15:28] <DaViruz> step/dir output
[13:15:34] <andypugh> Yes, that works fine. I have one.
[13:16:08] <DaViruz> great, thanks
[13:17:01] <andypugh> No, wait, sorry, I got confused
[13:17:15] <andypugh> I have a 7i69 and a 7i76
[13:17:20] <andypugh> Let me check..
[13:18:50] <andypugh> OK, it will work, it is just not one that I have checked.
[13:20:09] <DaViruz> nice. i wasn't sure if the rs422 remote connection was good enough latency-wise
[13:21:12] <andypugh> It's fine, it is meant for motion control. You wouldn't want to do software stepping through it, but for gpio they all work nicely.
[13:22:35] <DaViruz> i do miss a remote card with servo interfaces though
[13:23:36] <andypugh> 7i77?
[13:24:55] <andypugh> Though I am not sure which channels are SSLBP and which are PWM etc.
[13:24:58] <DaViruz> with rs422 connection i mean
[13:25:39] <andypugh> Some of those channels are rs422, I can't recall which :-)
[13:25:56] <DaViruz> well, rs422 input so to speak
[13:26:20] <andypugh> The 25-pin connector carries SSLBP in that config, it might just be a matter of wiring..
[13:26:47] <DaViruz> what's sslbp?
[13:27:05] <andypugh> The Mesa serial protocol
[13:27:09] <DaViruz> oh.
[13:28:48] <andypugh> I guess you are not in the market for a 5i25 to go with it?
[13:31:18] <DaViruz> i might be, i have to do more research
[13:31:39] <DaViruz> this was all clear to me until i began looking at the remote stuff
[13:33:00] <andypugh> Yeah, plugging in RJ45 cables and having it all just work is quite compelling isn't it?
[13:33:15] <DaViruz> i'm thinking i want a rs485 connection to my vfd, so i'm sort of leaning towards the 5i21
[13:33:26] <DaViruz> it sure is
[13:35:14] <andypugh> 5i23 is a fair bit cheaper.
[13:35:28] <andypugh> (Or have I got them confused again?)
[13:35:34] <DaViruz> actually i'm not really sure what the hell i'm doing. i'm sytill building on this crappy home built cnc bench milll
[13:35:41] <DaViruz> when i have a nice large sturdy VMC
[13:36:48] <DaViruz> with powerful servos, nice ball screws, analog spindle control, all the good stuff i've always dreamed about ;)
[13:36:59] <andypugh> And just because there is RS485 physical compatibility it doesn't mean that the communications protocol is there. You would be wanting to use a UART module?
[13:37:44] <DaViruz> the vfd speaks modbus, so coding a module that sends apropriate commands is fairly trivial
[13:40:20] <DaViruz> i have a few rs232-rs485 converters in the junk box, but having it inside the mesa card would be much neater.. :-)
[13:40:43] <andypugh> Are you sure it isn't one of the cheap chinese ones that don't speak any form of Modbus known to man?
[13:40:44] <DaViruz> i'm not really building this out of neccesity, more for the fun of building it
[13:41:19] <DaViruz> it's an omron vfd, and the protocol is fully documented
[13:41:57] <andypugh> Should be fine then.
[13:42:27] <andypugh> I think there is support for the Hostmot2 UART modules somewhere.
[13:43:01] <andypugh> As in, I recall writing something, but I don't know which version it is in.
[13:50:26] <awallin> blah, debian packaging is just so much fun... endless dependency/build/install errors...
[13:53:15] <Ekkeri> DaViruz, I have 7i52 which has 2xrs485 but those can't be used with modbus
[13:54:25] <PCW> Just need a SSERIAL SSMODBUS firmware :-)
[13:54:30] <Jymmm> awallin: debian or ubuntu?
[13:54:40] <Ekkeri> DaViruz, and I have Omron vfd too (Hitachi)
[13:55:34] <Ekkeri> PCW, when it will be released? ;)
[13:55:59] <Jymmm> Ekkeri: as soon as you finish writting it
[13:56:14] <Ekkeri> :p
[13:56:20] <Jymmm> =)
[13:56:39] <PCW> Well since its taken us a pretty big chunk of time to get SSLBP where it is, no time soon
[13:56:42] <Jymmm> 50/58 emc/linuxcnc
[13:57:00] <Jymmm> Yes, I'm keeping score =)
[13:58:03] <PCW> OTOH someone is putting a Dumb8 assembler on source forge
[13:58:11] <DaViruz> Ekkeri: oh? i assumed you got some sort of uart device you could send serial data to
[14:05:31] <andypugh> PCW: What's the Hostmot2 UART protocol that syyl (?) is using?
[14:07:26] <PCW> Issy/Sivar? Its their own protocol
[14:08:35] <andypugh> I guess it would be a relatively small change to puch Modbus through that module?
[14:08:37] <alex_joni> Jymmm: 50/58?
[14:09:01] <Ekkeri> DaViruz, I have only cheap rs232-485 converter
[14:09:06] <PCW> I think the gotcha with MODBUS is that the current driver is a userland thing Not sure that MODBUS can really be real time at all
[14:10:46] <andypugh> I am trying to work out if I hallucinated the whole UART driver thing...
[14:11:39] <Ekkeri> I will use stepgen for speed&dir and use modbus to just monitor things.. fast loadmeter would be nice though
[14:12:30] <Ekkeri> but there's analog output for that, maybe i will use it
[14:12:58] <andypugh> Anyway, a previous query was whether the 7i77 can be connected to anything except a 5i25. My impression is that it is mainly a wiring issue?
[14:14:19] <DaViruz> i would be very interested to know what's going on in that dsub25 connection
[14:14:53] <Ekkeri> PCW, have there been a batch of 7i73 before?
[14:16:18] <Ekkeri> It takes over a month to get one if I order one :)
[14:17:20] <DaViruz> i find it kind of hard to believe it is as simple as 4 wire rs422 when they chose a bulky db25 connector?
[14:19:37] <Ekkeri> db25?
[14:20:17] <Ekkeri> u mean db9?
[14:20:29] <DaViruz> i mean db25
[14:20:52] <PCW> There's no reason you could not connect a 7I76 or 7I77 to a 50 pin FPGA cards with a adapter
[14:21:03] <Ekkeri> oh..
[14:21:32] <DaViruz> PCW: how many wires are required?`
[14:22:26] <Ekkeri> I have db25 in my servodrives
[14:22:35] <Ekkeri> for 4 wires :)
[14:23:10] <andypugh> Ekkeri: We mean a very specific D25
[14:23:16] <PCW> Thats all thats connected?
[14:23:32] <Ekkeri> yup, 6-pin/wire thou
[14:25:21] <andypugh> Ekkeri: I thing D-sub are rated 7A per pin.
[14:25:52] <andypugh> I rather like the hybrid D-subs, where you can fit 40A pins, or Co-Ax, or pneumatic, or oprical...
[14:25:53] <Ekkeri> jup, that's why there are so many of them used
[14:25:57] <PCW> Ekkeri We have 7I73s hardware ready to go, but because it has so damn many modes
[14:25:59] <PCW> we are having to update our tools that write the realtime RPC code to allow a larger number of hardware modes
[14:27:15] <Ekkeri> jup, that's why there are so many of them used
[14:27:18] <Ekkeri> damn.
[14:27:52] <Ekkeri> changed from phone to pc and failed :)
[14:27:55] <PCW> You can say that again
[14:28:38] <andypugh> I am thinking of using an 18W3 for my brushless motor, though there is no need, as the current is low enough for normal pins.
[14:28:54] <Ekkeri> PCW, ok, I was just wondering because Duzi said something that made me think he had them already but out of stock now
[14:29:50] <DaViruz> the only hybrid dsub i have is a 13W3 video connector on my SGI workstation
[14:30:02] <DaViruz> pretty neat thing
[14:30:52] <Ekkeri> http://youtu.be/vQU9YEp4lXE got some movement from my mill today
[14:30:59] <andypugh> DaViruz: Yes, that is the most common example of quite a large family
[14:31:44] <DaViruz> no wait, i have a bunch of supercomputer power supplies that uses hybrid dsub connectors for backplane connection
[14:31:58] <DaViruz> i think there are 4 high current pins and a few normal pins in them
[14:32:29] <andypugh> It seems that I never pushed the Hostmot2 UART driver, do you think I should?
[14:32:34] <DaViruz> pretty hefty power supplies, three phase 400V input and 48V 73A output..
[14:32:40] <Ekkeri> andypugh, sure! :)
[14:35:04] <DaViruz> the backplane accepts four of them and connects them in paralell for a total of 292A and 14kW..
[14:35:13] <Ekkeri> :)
[14:35:52] <ve7it> Ekkeri, what servo motor is on your mill.... looks like sanyo-denki
[14:35:59] <Jymmm> alex_joni: No.... 2012-01-19 11:47:46 Jymmm: 50/58 #emc/#linuxcnc
[14:36:23] <Jymmm> alex_joni: Now.... 50/59 #emc/#linuxcnc
[14:36:48] <Ekkeri> ve7it, some cheap chinese stuff, Motionking BL70-313 or something like that
[14:37:09] <ve7it> cool
[14:37:24] <Ekkeri> rated 300W, peak 900W
[14:38:05] <ve7it> I have 3 sanyo motors about the same size looking for drivers and a machine
[14:38:42] <ve7it> I am considering a mesa card/irams solution for drivers
[14:39:12] <Ekkeri> http://www.granitedevices.fi/index.php?q=servo-drive-vsd-e I have those
[14:39:50] <Ekkeri> I think they are a little overkill, but they are from my country, had to buy them :)
[14:40:54] <DaViruz> the granite drivers are nice, but it's annoying that they need a separate power supply
[14:41:02] <DaViruz> i wish they'd develop mains capable drivers
[14:41:44] <DaViruz> oh they offer power supplies now, that's nice
[14:42:07] <Ekkeri> http://www.granitedevices.fi/index.php?q=home AC Powered Drives / 22 September 2011
[14:42:14] <Ekkeri> not sure if/when they are coming..
[14:42:52] <DaViruz> oh.
[14:42:59] <Ekkeri> like that RS485 thing :)
[14:43:34] <Ekkeri> "estimated to be ready before October" and that's 2010 :)
[14:43:42] <DaViruz> if/when the ac powered drives come i'll get a set
[14:44:31] <DaViruz> for the sake of sponsoring my neighbouring country if nothing else ;)
[14:46:11] <Ekkeri> wow, Swede sponsoring Finnish? are you kidding me? ;)
[14:46:53] <DaViruz> you guys need all the help you can get ;)
[14:47:00] <Ekkeri> :D
[14:47:36] <Ekkeri> what Omron do you have btw?
[14:48:36] <DaViruz> sysdrive 3G3JV
[14:49:24] <Ekkeri> ok, I have MX2
[14:49:44] <Ekkeri> and Hitachi WJ200, which is basically the same VFD
[14:49:54] <Ekkeri> since that Omron is made by Hitachi
[14:50:05] <Ekkeri> and.. http://ekke.kapsi.fi/temp/.omron_hitachi.png
[14:50:32] <Ekkeri> other manual had +200 more pages though
[14:50:34] <DaViruz> looks familiar :)
[14:54:41] <Ekkeri> I was ordering a EMI filter for my Hitachi, but that damn salesman sold me a second VFD.. and filters for both
[14:55:19] <awallin> Jymm: trying to build some packages for ubuntu. I'm getting errors if I specify virtual packages as dependencies..
[14:55:35] <DaViruz> i once ordered a motor transformer, and the saleseman sent me a sewage pipe instead
[14:55:50] <Jymmm> awallin: Yeah, UBUNTU dependancies are a real PITA. Debian, not so much.
[14:55:51] <DaViruz> i called him and complained, and he said he'd send the transformer right away
[14:56:00] <DaViruz> the next day i got a second, identical, sewage pipe
[14:56:37] <Jymmm> awallin: You might talk with alex_joni, he might have some insight
[14:56:49] <Ekkeri> DaViruz, nice :D
[15:00:43] <awallin> Jymm: so I've built it now successfully by enabling "universe" in pbuilder. How is that done for launchpad-builds?
[15:03:26] <andypugh> I just turned all the power off the careless way..
[15:05:29] <Ekkeri> I have PSU in the front in my garage pc.. and its power switch about knee-high when I'm sitting in front of it :)
[15:06:14] <andypugh> This was all the power in the house. At least I know that my machine ground is good.
[15:13:59] <Mjolinor> I once turnd off the street the careless way, blew the fuses in the sub station
[15:26:19] <Ekkeri> http://poscope.com/ponet_kbd48cnc_xxx damn that looks nice, and have leds :/
[15:32:49] <Ekkeri> don't know what keys/keypads to use with that 7I73, any suggestions?
[15:34:10] <andypugh> Ekkeri: You probably want a full alphabet though...
[15:34:26] <andypugh> (For a keyboard, not for the 7i73)
[15:36:20] <mrsun> does anyone know what angle dovetails the Sieg X1 has ?
[15:37:48] <andypugh> mrsun: It probably depends which cutter they used that day.
[15:38:22] <Mjolinor> such faith in the repeatability of manufacture :)
[15:38:27] <Ekkeri> :P
[15:39:00] <mrsun> haha =)
[15:40:18] <mrsun> i wish i could have access to a mill on the weekends
[15:41:43] <Ekkeri> andypugh, I think I could manage without that right XYZ etc. matrix since I have a pendant
[15:41:54] <andypugh> They definitely chose the width of the slot for my tailstock bolt that way. It means that there is only one undersized shoulder for the bolt head, but it's OK because the head has bent round and wedged now.
[15:46:29] <Jymmm> awallin: I'm really of no help there. I've just had issues over the years with dependancies + ubuntu is why I'm aware of it.
[15:46:35] <Ekkeri> http://www.cnc4pc.com/Store/osc/product_info.php?cPath=40&products_id=238 hmmph.. too much electronics with that one too :/
[15:49:48] <mrsun> hmm, has to be 60 degree
[15:50:02] <Jymmm> I WISH it was at least 60f here
[16:04:37] <mrsun> ough, this is a freakin horror show
[16:05:07] <mrsun> used a 60 degree triangle cutter thingie to check the dovetails, well they start out at 60 degree and end up at like 55 degrees in the other end ...
[16:05:23] <mrsun> some of them are 60 degrees, others are like 65 degrees
[16:05:37] <mrsun> please god shoot me now :P
[16:06:04] <Mjolinor> nah, its jsut a warp in the space time continuum
[16:06:48] <mrsun> must be ...
[16:07:01] <mrsun> it makes me quite sad that i payed so much for such a bad machine ...
[16:07:09] <mrsun> well you live and you learn
[16:07:31] <bill20r3> It came with free lesson, I suppose.
[16:08:32] <mrsun> well next time i buy something i will have my whole arsenal of measuring tools and rip the thing apart before i buy it, its my consumers right .. i think :P
[16:08:57] <Mjolinor> may struggle with that at soem shops
[16:09:15] <Mjolinor> like to see you do it when buying a car though
[16:11:11] <mrsun> thing is that to correct all the dovetails everything will get offset to the side and screws etc wont line up anymore :/

[16:22:54] <Jymmm> mrsun: Isn't that what Move-A-Screwhole (tm), By RONCO... AS SEEN ON TV are for?
[16:25:00] <slime> have anybody experience in the modified elm chan russian servo controller?
[17:03:19] <andypugh> cradek: Wierd things happen if you hit quill-up in Touchy during a programme. (Well, I don't know what happens with a machine connected, but running semi-sim (feedback short-circuited) it stops to think, gives an error, and moves Z in a step change.
[17:34:25] <andypugh> My VM is broken. I guess it is good that it is only a VM. apt-get won't work...
[17:47:55] <andypugh> intersting, a list of security cameras with no passwords etc. http://pastebin.com/vEWCQqMe
[17:51:53] <andypugh> Ah, I thought they were just security cameras, it seems some are in people's houses. That's rather careless of them.
[18:22:38] <JT-Shop> a little glimpse into history http://cnc-toolkit.com/Tux-with-BDI-Manual3.jpg
[18:31:17] <andypugh> Night all
[18:38:07] <JT-Shop> pcw_home: any problems using a short 1' ribbon cable from the back of the case to the 5i25?
[18:41:12] <PCW> For the second port?
[18:44:22] <JT-Shop> just to connect the first port to the parallel port cable in a neat way
[18:44:55] <JT-Shop> it has a plug on each end and the thing to fit in the slot
[18:47:51] <JT-Shop> like this but with DB25 on both ends http://www.newegg.com/Product/Product.aspx?Item=N82E16812196220&nm_mc=OTC-Froogle&cm_mmc=OTC-Froogle-_-Adapters+and+gender+changers-_-Cables+To+Go-_-12196220
[19:00:24] <PCW> I'm not sure why you need this normal 5I25 connection is 5I25 DB25F --> M-M DB25 IEEE cable --> daugthercard DB25F
[19:04:39] <JT-Shop> I'm sorry I meant the 7i76 card
[19:08:30] <PCW> still dont understand 5I25 --> MM DB25 cable --> 7I76 would be the normal way
[19:10:15] <JT-Shop> the cable with the blue ends is DB25 to DB25 http://imagebin.org/194538
[19:10:33] <JT-Shop> it used to go to my cnc4pc breakout card
[19:10:54] <JT-Shop> the cable then plugs into the back of the computer case like normal
[19:12:59] <JT-Shop> ohh, the dinner bell is ringing
[19:13:09] <PCW> Sure you can us a flat cable MM DB 25 instead of a IEEE MM cable if ts only 1 or 2 feet long no bracket invloved
[19:14:13] <JT-Shop> the IEEE MM cable will go from the 525 case to the power supply/drive case and the ribbon would just be inside of that case
[19:15:21] <PCW> OK so you need a M-F ribbon
[19:17:51] <PCW> shorter is better (you lose the IEEE1284 shield at the power/drive box)
[20:11:32] <Nick001> Who supplies ieee db25 cables 1-2 ft long? The shortest I found was 3'
[20:13:51] <Jymmm> http://onefootlongieeedb25cables.com/
[20:18:03] <Nick001> are you sure about that address? gives me a default search from my isp
[20:18:04] <elmo40> oh. name change... interesting. It was bound to happen ;)
[20:18:25] <elmo40> Jymmm is a hooligan ;)
[20:20:03] <elmo40> http://www.cablestogo.com/product.asp?cat_id=917&sku=02653
[20:20:11] <elmo40> like that?
[20:20:22] <Guest85744> http://amalas.eu/~slime/PROJECTS/CNC/big/spannplatte/DSCI0028.JPG
[20:20:43] <elmo40> Guest85744: that is lovely :)
[20:20:54] <elmo40> just need more power at the tip
[20:20:55] <Guest85744> argh
[20:21:02] <slime> ?
[20:22:01] <Jymmm> wth is that thing, a dremel?
[20:22:08] <slime> hr
[20:22:13] <slime> no, kress
[20:22:20] <Jymmm> horsepower?
[20:22:22] <slime> dremel is about 80W
[20:22:36] <slime> this is about 1000W
[20:22:43] <Jymmm> horsepower?
[20:22:47] <slime> yes
[20:23:02] <Jymmm> how much horsepower?
[20:23:10] <slime> öhm
[20:23:17] <slime> i dont know
[20:23:29] <slime> ask google
[20:23:32] <slime> :D
[20:23:56] <Jymmm> I'd say trash it and get something that is rated in HP
[20:24:25] <Nick001> <elmo40>That's the one - thanks
[20:24:36] <jackc> why did we move?
[20:24:46] <slime> 1000 watts = 1.34102209 hp
[20:25:59] <Jymmm> jackc: Did you read the link that Tom_itx gave you in the other channel?
[20:26:08] <slime> wow Jymmm where you were from? further east, beyond Mississippi? or what? these lands you'd use Watts instead.
[20:28:16] <Jymmm> Watts is something that a device draws, not necessarily what it produces.
[20:28:43] <Jymmm> to me that is
[20:29:58] <slime> kind of right still unnecessarily punching people, guy
[20:30:05] <slime> it is working, though
[20:30:11] <slime> to me that is
[20:30:56] <slime> and never forget about the rest of the world that mostly DONT use miles and such
[20:30:56] <Jymmm> With as much as is in the machine, it's like tossing MC engine into a mac truck
[20:31:29] <slime> dont move to fast, that means

[20:41:41] <Jymmm> JT-Shop: jthornton Welcome back! Looks like you got your cbales fixed
[20:42:21] <Jymmm> JT-Shop: Nitrogen regulators. they come in flow and pressure flavors, correct?
[21:06:28] <A2Sheds> I suppose I'll get used to it in here, it feels like new tools
[21:16:51] <skunkworks> heh
[23:28:15] <servant742> .
[23:37:38] <Jymmm> 45 to 52
