#emc | Logs for 2010-06-01

[00:54:05] <Endeavour> Greetings
[04:01:30] <KimK> Hey, Endeavour, how's it going? Getting your questions answered?
[04:02:53] <Endeavour> Some of 'em.
[04:03:20] <Endeavour> Just been doing general research lately. I think I probably will end up using EMC2, though.
[04:03:22] <Endeavour> Seems nice.
[04:03:48] <KimK> Glad to hear it. I think you'll be pleased.
[04:05:50] <Herp> I couldn't find a general CNC channel so I will pose my question here - which is actually more electronics focused but still on CNC. How do I go about setting up communication with a PIC 18 series chip through a USB port? (The goal is for it to drive stepper motors)
[04:06:50] <archivist> herp, dont bother usb has delays that could scupper your design
[04:07:07] <Herp> I only have USB ports
[04:07:40] <KimK> Yeah, I was going to say, the guys here have been there, done that and got the t-shirt.
[04:08:48] <KimK> Unless you don't really want to cut anything, just "spin post-it notes", as I heard one person say.
[04:11:14] <KimK> You only have USB ports on what kind of a PC? Maybe there's something that can be added to help. Parallel port? PCI card? That new port (what is it on the, Mesa, what, 3x20?)
[04:11:38] <Herp> a desktop
[04:11:45] <Herp> but all my computers only have USB ports'
[04:12:17] <archivist> add an interface card
[04:12:24] <KimK> OK. Got any open PCI slots for a parallel card? (cheapest solution). What are your goals? Where do you want to end up?
[04:12:36] <Herp> yes I have open PCI slots
[04:13:11] <KimK> Get a parallel port card, but there's one chipset to avoid. (Drat, which one is it?)
[04:13:42] <Herp> I want to drive stepper motors for a CNC mill, I thought I could use a PIC to interface with the USB port but that sounds like it will not work?
[04:13:42] <Endeavour> http://www.newegg.com/Product/Product.aspx?Item=N82E16815166007 Get that one.
[04:13:55] <Endeavour> Serial lags.
[04:14:01] <Endeavour> You want something real time.
[04:14:25] <KimK> It will "almost" work. And no matter what you do to improve it, it will still "almost" work.
[04:14:32] <Herp> lol
[04:14:45] <archivist> there must be no delays to the stepper control signals
[04:14:59] <Endeavour> Need to find a GeckoDrive cheap or get someone to let me borrow one for a bit. :P
[04:15:21] <archivist> and variation in arrival time will likely cause it to lose steps or stall
[04:15:24] <archivist> any
[04:15:38] <Herp> You could maybe do a complicated setup where the PIC delays the output a little and acts like a buffer but since you can buy a printer port card that sounds easiest
[04:18:00] <Herp> well with that issue out of the way, has anyone built their own driver circuit with success?
[04:18:25] <KimK> Now if you have a larger, more sophisticated machine in mind (lots of DC I/O, maybe a lathe with a turret or two, or a mill with a tool changer, maybe even servos instead of steppers), maybe you want to consider a better interface from the beginning?
[04:19:07] <Herp> at most it would have 4 motors
[04:19:17] <Herp> 3 for x/y/z and 1 for table
[04:19:29] <archivist> you soon want 5
[04:19:31] <KimK> But if you're running say, a tabletop mill with Nema23 steppers, then fine, go parallel.
[04:20:12] <Herp> the parallel would work for what I want but what other interface options are there?
[04:20:18] <Herp> either USB or serial or parallel port
[04:20:34] <Herp> ?
[04:21:02] <archivist> pci interface card from mesa with an fpga on board
[04:21:56] <KimK> Endeavour: Do you want the stepper out or the servo out Gecko? (The step/dir input to servo output method will bother you in the long run on EMC2).
[04:22:56] <KimK> Herp: Take a look at the "Anything I/O" controller cards and daughter cards (many!) at http://www.mesanet.com/
[04:24:25] <Herp> hmmm
[04:24:41] <archivist> herp often users use an older pc which does have parallel also some have better latency tests
[04:25:19] <Endeavour> Steppers, KimK
[04:26:11] <Herp> hmm
[04:28:19] <Herp> parallel port card should work I think
[04:28:22] <KimK> Herp: For a new machine, you might pick a 5i23 controller and up to 3 daughter cards. Maybe a 7i47 for 6-channel stepping (with optional encoder feedback)? Maybe a 7i33 4-channel servo? (Oops, no, you said steppers.) Maybe a 7i37 16-in 8-out DC I/O card? Hey, there's still one port left!
[04:29:08] <Herp> looks a little more involved to set up then what I want tbh
[04:29:41] <KimK> Endeavour: Steppers, OK, no problem then. I hate to see users install servos with EMC2 and then mask them behind a step/dir interface. Not helpful.
[04:30:01] <KimK> Herp: OK, no problem. A parallel port it is then.
[04:30:45] <KimK> Herp: And if Endeavour has a recommended part number for you, go with that one then.
[04:31:13] <Herp> ok, I have book marked that one PCI card
[04:31:19] <Endeavour> I'm just a parrot. Someone else here told me that parallel card. ;)
[04:32:03] <KimK> Well, if you got that advice here, I'm sure it's good advice, then.
[04:32:25] <Endeavour> Indeed.
[04:37:33] <KimK> Good chatting with everybody. I'm off for a bowl of stew. Back tomorrow. Goodnight all.
[05:16:19] <Endeavour> Anyone around still?
[05:24:35] <elmo40> nope
[05:24:43] <toastydeath> I NEED A HERROOOO
[05:24:49] <toastydeath> OHHH
[05:25:01] <toastydeath> is anyone else really drunk.
[05:44:20] <elmo40> hrmm... worth converting the lathe? http://qurl.org/S01
[05:44:59] <toastydeath> that's a cute lathe
[05:52:00] <elmo40> all that junk for $10,000
[05:52:11] <elmo40> don't think it is worth it
[05:57:13] <toastydeath> oh, definitely not
[05:57:17] <toastydeath> i'm just saying it's a cute late
[05:57:18] <toastydeath> *lathe
[06:15:35] <Endeavour> * Endeavour needs to sell his 7x12
[09:15:17] <Valen> nope
[09:21:34] <fragalot> Beep.
[12:33:43] <Jymmm> Looks clean... http://sfbay.craigslist.org/sby/tls/1769109956.html
[13:00:38] <elmo40> Jymmm: I want it!
[13:00:49] <elmo40> kind small to get the 4th axis on it, though...
[13:03:20] <sealive> the mashine has the old very painfull elektronik
[13:11:11] <sealive> 1st atempt to cut the tube in the golf http://mms.piersystem.com/deepwater1
[13:21:56] <elmo40> always says I am behind a firewall.
[13:22:04] <elmo40> I wonder what odd port number they are using
[13:25:37] <Dave911> sealive: Is that part of the BP effort to stop the oil flow? Looks like a live feed.
[13:26:08] <Dave911> I got right in and I have most ports blocked ... via a hardware firewall
[13:31:40] <sealive> Dave911: yes
[13:32:48] <Dave911> Cool... thanks... doesn't look like much going on at the moment apparently ...
[13:53:22] <Endeavour> Greetings
[14:01:24] <JT-Work> hi
[14:10:10] <bricofoy> hi
[14:10:18] <SWPadnos> hi
[14:10:39] <bricofoy> does someone knows if there is a way to desactive a button on a pyvcp panel ?
[14:10:55] <SWPadnos> in HAL?
[14:11:10] <SWPadnos> (rather than just removing the button from the pyvcp panel)
[14:11:12] <Jymmm> HAL Now Brown Cow!
[14:11:14] <bricofoy> I've some buttons calling for MDI commands, I would like to inactivate them when a program is running
[14:11:25] <bricofoy> not removing the button
[14:11:34] <SWPadnos> ok
[14:11:34] <bricofoy> but turning it gray an inactive
[14:11:40] <JT-Work> A text button controls a "bit" halpin. The halpin is false until the button is pressed then it is true. The button is a momentary button.
[14:11:42] <JT-Work> The text button has an optional disable pin that is created when you add <disable_pin>true</disable_pin>.
[14:11:50] <JT-Work> http://www.linuxcnc.org/docview/html//hal_pyvcp.html#r1_6
[14:11:58] <SWPadnos> bricofoy, yes, its possible :)
[14:12:04] <JT-Work> ^ from the docs
[14:12:04] <bricofoy> I see :)
[14:12:24] <bricofoy> thanks, had not found that in the french doc
[14:13:11] <JT-Work> it might not be as up to date as the english one
[14:13:53] <SWPadnos> feel free to translate more though
[14:14:18] <JT-Work> the most up to date docs are on the web site
[14:14:34] <bricofoy> well, I'm not sure something I translate will be fully understandable by english people :P
[14:14:36] <SWPadnos> and maybe email Francis Tisserant anything you do, he's the primary french tanslator
[14:14:50] <SWPadnos> well, that's OK, we won't know anyway :)
[14:14:58] <SWPadnos> translate *to* french :)
[14:15:20] <bricofoy> hahem, time fom me to sleep....
[14:15:25] <bricofoy> for
[14:15:28] <SWPadnos> oui
[14:15:32] <bricofoy> :P
[14:15:51] <bricofoy> too much HAL at night... and I'm done :P
[14:17:06] <Jymmm> SWPadnos: http://www.dealextreme.com/details.dx/sku.33189
[14:18:19] <SWPadnos> huh. I wonder how fast it is
[14:18:42] <Jymmm> SWPadnos: I'll tel you for $17
[14:18:43] <Jymmm> tell
[14:19:23] <SWPadnos> ok, I'll buy you one of those, you go out and get 10 Nikon D700 cameras, and tell me how long it takes to get 14MB RAW files from all of them at once
[14:20:20] <Jymmm> SWPadnos: No problem
[14:21:10] <elmo40> 480Mbps / 10 ?
[14:21:20] <Jymmm> SWPadnos: Is that something that might be of use to you?
[14:21:22] <elmo40> the problem with USB is only one device can 'talk' at a time.
[14:21:31] <SWPadnos> well, I don't know how much the design of the hub affects transfer speed
[14:21:54] <elmo40> and, only one direction to-from device to computer
[14:21:55] <SWPadnos> like with ethernet switches, where there's some processing overhead
[14:22:03] <elmo40> firewire is much gooder :P
[14:22:13] <SWPadnos> sure, USB sucks, but since that's what all the cameras have ...
[14:22:18] <elmo40> I know
[14:22:19] <elmo40> lame
[14:22:33] <elmo40> they should have went with firewire. the older camcorders did!
[14:22:36] <elmo40> why did they stop?
[14:22:41] <SWPadnos> Jymmm, possibly. you get into cable length issues when you try to concentrate all the ports in one place
[14:22:42] <Jymmm> old skool
[14:23:21] <Jymmm> SWPadnos: Ah, well i remember you mentionng something about it a ways back, jsut came across it and let you know
[14:23:23] <elmo40> Jymmm: maybe RAID 10 memory sticks? :P
[14:23:32] <SWPadnos> elmo40, they stopped because firewire was always more expensive, and much less common on PC motherboards (IMO)
[14:23:37] <SWPadnos> yeah, thanks
[14:24:00] <SWPadnos> I'm looking at doing something small in the next couple of weeks, and a couple of 10-ports may do the job
[14:24:06] <elmo40> only more expensive due to lack of wide spread use... cable is a cable.
[14:24:08] <SWPadnos> then again, a couple of 8-ports would too :)
[14:24:30] <SWPadnos> sure, the cables are about the same, but the port itself was never all that popular on PCs
[14:24:31] <Jymmm> SWPadnos: Oh, cool. I think it looks slick. a lot better than some I've seen.
[14:24:37] <SWPadnos> yep
[14:24:42] <elmo40> port is a port. the technology is over a decade old. it should be cheap now
[14:24:45] <SWPadnos> looks like you could almost mount it to something
[14:24:49] <Jymmm> Apple is dropping FW in favor of USB3
[14:24:59] <Jymmm> SWPadnos: velcro
[14:25:01] <elmo40> when is usb3 coming?!?!
[14:25:04] <SWPadnos> tell that to all the motherboard manufacturers
[14:25:08] <SWPadnos> USB3 is here
[14:25:13] <elmo40> I see 3 mobos with it. but no devices
[14:25:22] <SWPadnos> no, not many devices
[14:25:30] <Jymmm> just like FW
[14:25:31] <SWPadnos> there are plenty of motherboards though
[14:26:03] <Jymmm> I will say this, I will surely miss TARGET MODE <sniff sniff>
[14:26:16] <SWPadnos> and actual isochronous mode
[14:26:34] <Jymmm> SWPadnos: Do you know what Target mode is?
[14:26:49] <SWPadnos> yeah, the MACs have it, they act like a hard disk
[14:26:55] <SWPadnos> oops, Macs
[14:27:30] <Jymmm> SWPadnos: Yeah, just makes all the devices dumb, I just love it!
[14:28:00] <SWPadnos> http://www.newegg.com/Product/Product.aspx?Item=N82E16817364024
[14:28:02] <elmo40> see, firewire is far superior: "Typical USB PC hosts rarely can sustain transfers exceeding 280 Mbit/s, with 240 Mbit/s being more typical. This is likely due to USB's reliance on the host processor to manage low-level USB protocol, whereas FireWire delegates the same tasks to the interface hardware (requiring less or no CPU usage). "
[14:28:19] <Jymmm> hdd failing? target mode and dump to image file!
[14:28:54] <elmo40> why anyone would make a device for usb and not fw is strictly an accountants thought pattern, not an engineers.
[14:28:56] <SWPadnos> ... thus making the interface hardware more expensive, making the whole thing less popular ...
[14:29:05] <elmo40> my point.
[14:29:23] <elmo40> but for an extra $0.50 per device (come on, how bloody expensive is it?) it is worth it
[14:29:28] <SWPadnos> it's not the first time a superior technology lost in the marketplace
[14:29:43] <Jymmm> BetaMax
[14:30:01] <SWPadnos> there may be some licensing thing with FW actually, I thought it was invented by Apple and Sony
[14:30:44] <elmo40> even NASA uses it ;)
[14:30:45] <elmo40> NASA's Space Shuttle also uses IEEE 1394b to monitor debris (foam, ice) which may hit the vehicle during launch
[14:40:30] <Jymmm> SWPadnos: I have a firewire lipstick camera if you're interested =)
[14:41:09] <SWPadnos> hmmm. how long a cord can we get for that?
[14:41:17] <SWPadnos> (and does it work in Linux?)
[14:41:25] <Jymmm> http://www.amazon.com/Apple-iSight-FireWire-Computers-M8817LL/dp/B0000AKACN
[14:41:42] <elmo40> anyone have one of these they are not using? http://qurl.org/U01
[14:41:55] <Jymmm> but this one has the laptop/display mount, not stand.
[14:42:27] <SWPadnos> elmo40, yeah, like I'm using the box for a footrest
[14:42:29] <SWPadnos> NOT!
[14:42:57] <SWPadnos> firewire has a pretty short max cable length too though, I think
[14:43:25] <Jymmm> 14.5ft
[14:43:33] <Jymmm> http://en.wikipedia.org/wiki/IEEE_1394_interface
[14:43:37] <SWPadnos> yeah, about the same as USB
[14:43:38] <Jymmm> Created by Apple
[14:43:41] <SWPadnos> 4.5 meters
[14:46:23] <elmo40> found a different version: http://qurl.org/V01
[14:47:21] <elmo40> so, USB3 will support 400MB / s
[14:47:24] <elmo40> nice
[14:47:45] <SWPadnos> 5Gbit/second, I think
[14:49:14] <elmo40> approx 400 megabytes per second
[14:49:58] <elmo40> same as firewire 3200
[14:50:17] <SWPadnos> the wire speed is listed as 5 GBit/sec
[14:50:43] <SWPadnos> actual speed may be closer to FW3200 speed, because the USB protocol sucks
[14:51:04] <celeron55> i recall actual speed being 3Gbit/s
[14:51:47] <elmo40> but firefire is still 'realtime'
[14:52:12] <SWPadnos> http://en.wikipedia.org/wiki/SuperSpeed_USB#USB_3.0
[14:52:24] <SWPadnos> "A new major feature is the "SuperSpeed" bus, which provides a fourth transfer mode at 5.0 Gbit/s"
[14:52:47] <fragalot> anyone here halfdecent with brl-cad?
[14:53:00] <SWPadnos> try #brlcad
[14:53:01] <elmo40> and can supply up to 45W up to 30V! Insane
[14:53:03] <fragalot> wondering if I can update an object's attributes (size, location..)
[14:53:06] <fragalot> SWPadnos: k
[15:00:17] <bricofoy> I come back with my button-disabling problem
[15:00:42] <SWPadnos> yes
[15:01:14] <bricofoy> added <disable_pin>TRUE</disable_pin>, but got this : Error constructing button({'text': 'Reset', 'halpin': 'py-reset', 'disable_pin': 1}):
[15:01:14] <bricofoy> unknown option "-disable_pin"
[15:01:42] <bricofoy> <button>
[15:01:43] <bricofoy> <halpin>"py-reset"</halpin>
[15:01:43] <bricofoy> <disable_pin>TRUE</disable_pin>
[15:01:43] <bricofoy> <text>"Reset"</text>
[15:01:43] <bricofoy> </button>
[15:02:16] <bricofoy> tried to use a pin name instead of "TRUE" but same problem
[15:03:36] <bricofoy> ok, found something : http://www.linuxcnc.org/component/option,com_kunena/Itemid,20/func,view/catid,22/id,2518/limit,6/limitstart,6/lang,english/
[15:03:47] <bricofoy> I try...
[15:04:21] <SWPadnos> well, that sucks if it has to be capitalized like that
[15:04:34] <bricofoy> nope, same error
[15:05:25] <SWPadnos> could you put more of the error on http://pastebin.ca
[15:05:52] <SWPadnos> more of the terminal session that includes the error, that is
[15:06:35] <bricofoy> yep
[15:13:16] <bricofoy> http://pastebin.com/P7vNpcTF this is the output
[15:14:42] <bricofoy> http://pastebin.com/MdkrLA1W and my custompanel.xml
[15:17:35] <bricofoy> ok finally got it working
[15:17:39] <bricofoy> the doc is wrong
[15:17:55] <bricofoy> it is not <disable_pin> but <disablepin>
[15:19:09] <bricofoy> at least on the 2.4.0~pre I use
[15:20:30] <bricofoy> and disabling the button works well :)
[15:21:36] <JT-Work> bricofoy: I'll fix the docs thanks for catching that
[15:21:50] <tom3p> congrats! did you find that in the source, or trial & error?
[15:23:06] <tom3p> well the hint was unknown option "-disable_pin"
[15:28:20] <fragalot> sagCAD error messages ftw.
[15:28:24] <fragalot> it's all in japanese xD
[15:30:29] <bricofoy> found somethink about spelling in XML in a forum post, so tried here
[15:31:25] <bricofoy> ho, in fact this was said in the forum post linked here
[15:31:29] <bricofoy> in the page 1
[15:31:38] <bricofoy> but I see it just now :P
[15:32:00] <bricofoy> http://www.linuxcnc.org/component/option,com_kunena/Itemid,20/func,view/catid,22/id,2518/limit,6/limitstart,6/lang,english/
[15:32:14] <bricofoy> look on the previous page
[15:33:05] <_TwisT_> hi!
[15:33:52] <_TwisT_> Is there any chance tu run EMC2 with nvidia proprietary driver?
[15:34:16] <elmo40> worse things have happened ;)
[15:35:02] <_TwisT_> and what about "nv" driver? Is it good enougth for realtime purposes?
[15:35:18] <_TwisT_> I have Riva TNT2
[15:35:37] <itheos> ji
[15:35:39] <itheos> hi
[15:35:43] <_TwisT_> hello
[15:36:02] <itheos> isnt emc being built for lucid lynx?
[15:36:09] <itheos> its till hardy right?
[15:36:33] <cradek> there are experimental packages for lucid and some of us are working on it. the officialy supported distribution is hardy.
[15:37:01] <itheos> ok so till when can we have it for lucid?
[15:37:38] <cradek> what?
[15:38:04] <fragalot> * fragalot can't seem to find a CAD application on linux that agrees with him.
[15:38:08] <bricofoy> I'm unsing experimental packages on 9.10, works well
[15:38:12] <SWPadnos> itheos, there is no planned release date for lucid
[15:38:19] <itheos> ok :(
[15:38:40] <SWPadnos> like cradek said, we're working on it, and it'll be released when it seems like it;s ready
[15:38:50] <itheos> thanks :)
[15:39:00] <elmo40> fragalot: neither can I !
[15:39:20] <itheos> any other alternative you would recomend?
[15:39:29] <JT-Work> fragalot: I like SolidWorks
[15:39:47] <itheos> it isnt for linux i think?
[15:40:01] <pjm> hello
[15:40:38] <fragalot> elmo40: best one I could find sofar is QCad
[15:40:58] <itheos> fragalot, how about blendercad?
[15:41:09] <bricofoy> Qcad sucks
[15:41:16] <bricofoy> Varicad is a nice D one
[15:41:18] <bricofoy> 3D
[15:41:21] <fragalot> itheos: blender confuses me deeply (And the buttons below are too tiny for me to read :/)
[15:41:23] <bricofoy> and not so expensive
[15:41:24] <JT-Work> I use QCad on my plasma and Hardinge computers it only mildly sucks
[15:41:35] <fragalot> QCad "works*
[15:41:38] <itheos> :P
[15:42:12] <fragalot> I think i'm going to stick to windows & autodesk software for the CAD work..
[15:42:29] <_TwisT_> I've noticed, that response of a system slows down only at init and shutdown of 3D-acceleration (for example, opening and on closing of glxgears), but works smoothly while OpenGL context is running (I've used an "reset" button in latency-test just after glxgears launch)
[15:42:50] <bricofoy> try varicad, they have test version available for download
[15:42:59] <bricofoy> www.varicad.de
[15:43:26] <bricofoy> http://www.varicad.de/en/home/
[15:43:41] <_TwisT_> and varicad works well after 30 day limit, if rm -R ~/.varicad :)
[15:43:45] <fragalot> bricofoy: need to register for the trial thoough?
[15:44:04] <itheos> _TwisT_, haha good one :)
[15:44:53] <fragalot> LOL
[15:44:55] <tom3p> cad: try http://www.cad-schroer.com/
[15:45:03] <fragalot> in their example gallery, the electrical design section
[15:45:04] <itheos> anybody heard of http://www.ajaxcnc.com/ajax_software.htm
[15:45:14] <fragalot> they've created, what can only be interpreted as a suitcase bomb.
[15:45:30] <bricofoy> _TwisT_, yeah, but you still can't open the file created during the first 30 days, so...
[15:46:02] <bricofoy> fragalot, just have to provide an email I think
[15:48:25] <SWPadnos> SolidWorks used to work great in VMWare. almost full speed
[15:48:27] <SWPadnos> I don
[15:48:37] <SWPadnos> I don't know if they've screwed that up in the last few years
[15:49:24] <elmo40> sure they have
[15:49:35] <elmo40> with SW2010 it is super bloated.
[15:50:00] <elmo40> and they have completely integrated the COSMOS stuff
[15:50:11] <elmo40> last one that worked well was SW2004
[15:50:19] <elmo40> in VMware, that is
[15:50:21] <SWPadnos> ok, that's the one I used :)
[15:50:36] <elmo40> 07 was so-so. had a few hickups
[15:50:41] <elmo40> but 04 was more stable
[15:51:00] <MattyMatt> fragalot, with the mouse over the buttons panel, hold ctl & middle mouse button, and move the mouse forwards
[15:51:03] <elmo40> I wonder if it would run under Wine ;)
[15:51:09] <MattyMatt> it's so intuitive :)
[15:51:15] <SWPadnos> strangely, SW viewer 09 works almost perfectly under Winw
[15:51:18] <SWPadnos> Wine
[15:51:37] <elmo40> isn't there a CAM plugin for Blender?
[15:51:41] <elmo40> I know Inkscape has one
[15:51:49] <fragalot> MattyMatt: yeah... intuitive.. >.>
[15:51:53] <fragalot> elmo40: there is
[15:51:53] <SWPadnos> some video glitches when you rotate things around, but otherwise it seems fully functional
[15:52:03] <bricofoy> yeah inkscape plugin is good :)
[15:52:19] <SWPadnos> someone here was working on a blender CAM plugin
[15:52:21] <bricofoy> I use it quite often to make some wood engraving
[15:52:33] <MattyMatt> CAM plugin is basically the script I'm working on. it now does zigzags, drills and slots
[15:52:44] <SWPadnos> I guess it's MattyMatt :)
[15:53:16] <MattyMatt> and the original does 2.5D stuff too
[15:53:32] <tom3p> yoyoek's blender to gcode http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl/emcinfo.pl?action=browse&diff=1&id=GcodeGenerator
[15:54:22] <tom3p> MattyMatt, any links?
[15:54:39] <MattyMatt> not yet, I should get it on the wiki
[15:55:01] <tom3p> thanks
[15:55:39] <fragalot> what do you guys use to go from DXF -> Gcode?
[15:55:49] <MattyMatt> I'd like to get in touch with yoyoek first, to check I'm not stealing his version numbers :)
[15:55:53] <elmo40> fingers and notepad :P
[15:55:55] <fragalot> trying DXF2G-Code v0.1 atm but it seems.. unreliable
[15:56:18] <fragalot> elmo40: i'm starting to think that for simple things, that *is* the best option lol
[15:56:56] <elmo40> makes the brain work, too!
[15:56:58] <MattyMatt> his last version in 0.174, so should mine be 0.174-matt or 0.175 or what?
[15:58:15] <fragalot> elmo40: but we have computers for that :#
[15:58:44] <elmo40> computers to make parts, too
[15:58:55] <elmo40> but humans had to program it, design it, build it
[15:59:17] <fragalot> 'had'
[15:59:19] <fragalot> :3
[16:00:36] <fragalot> ANYWAYS, just gonna stick with the traditional method of using autocad to design, then program it myself.. seems to be the most reliable option
[16:05:37] <tom3p> MattyMatt, i found no email address on his site, so its your best guess
[16:08:57] <fragalot> PyCAM seems to be pretty neat for breaking bits
[16:10:37] <tom3p> anyone using the dorms at cnc workshop?
[16:11:38] <SWPadnos> ugh. gotta pay for that
[16:11:42] <SWPadnos> too bad since I
[16:11:44] <SWPadnos> ;argh
[16:11:56] <SWPadnos> too bad since I'll only be there for about 2 days
[16:13:15] <tom3p> bicycle path dorm to wokshop http://maps.google.com/maps?f=s&utm_campaign=en&utm_source=en-ha-na-us-bk-gm&utm_medium=ha&utm_term=google%20maps
[16:13:26] <tom3p> r
[16:14:22] <MattyMatt> that shows caracas to vancouver for me :)
[16:16:29] <KimK> Shows the starting map of the US for me. tom3p, get your dorm/bike map again, and then copy the link from the "link" near the upper left, I'd like to see your map.
[16:16:49] <KimK> oops upper right
[16:16:50] <tom3p> haha, it shows the USA map for me, oh well, put in Ypsilanti / ann arbor instead
[16:17:07] <KimK> * KimK thinks "his *other* left
[16:17:42] <skunkworks_> KimK: http://www.electronicsam.com/images/KandT/conversion/DSCF1184.JPG
[16:17:48] <skunkworks_> power!

[16:19:31] <elmo40> qurl.org that...
[16:19:36] <elmo40> why do people post large-ass links
[16:19:49] <fragalot> because it's easy
[16:20:03] <fragalot> and it's a bbigger target for you to click.
[16:20:16] <MattyMatt> complain to google
[16:20:55] <KimK> skunkworks_: Excellent, congrats. Sam, what are you and your dad doing about the workshop? I was thinking I could swing through La Crosse either before or after.
[16:21:00] <fragalot> skunkworks_: I'd say "neat." but i'm too jealous ^_^
[16:21:18] <skunkworks_> KimK: I have to start making plans :)
[16:21:23] <elmo40> my travel ;) http://qurl.org/W01
[16:21:43] <skunkworks_> we might drive over the UP for the heck of it.
[16:22:01] <SWPadnos> no Manitowoc -> Ludington ferry?
[16:22:24] <fragalot> elmo40: that was mighty confusing when I saw "london" there >.<
[16:22:25] <skunkworks_> SWPadnos: how much is it?
[16:22:30] <SWPadnos> lots
[16:22:31] <skunkworks_> I actually thought about that...
[16:22:33] <skunkworks_> heh
[16:22:35] <KimK> tom3p: Wait, the dorms are 4.3 bike miles from the community college?
[16:22:37] <SWPadnos> $100 or so, I bet
[16:22:47] <SWPadnos> but you get to not drive around Chicago
[16:23:04] <elmo40> fragalot: more then on London in the world ;)
[16:23:06] <SWPadnos> if you take the truck again, you'll probably save that much in gas
[16:23:09] <tom3p> 100$ exact afik 86 for 4 days * 16 for 4 clean sheets
[16:23:13] <skunkworks_> right - that is why we are thingking of taking the scenic route around the UP
[16:23:25] <elmo40> tom3p: pay extra for clean sheets???
[16:23:44] <tom3p> bring your own & do laundry or pay 4$/nite
[16:24:00] <SWPadnos> ouch! it
[16:24:04] <SWPadnos> argggghhhh
[16:24:10] <SWPadnos> it's way more expensive now
[16:24:10] <skunkworks_> tom3p: 4 days to cross?
[16:24:15] <SWPadnos> http://www.ssbadger.com/content.aspx?Page=schedule
[16:24:24] <SWPadnos> he's talking about the dorm rates
[16:24:46] <tom3p> sorry lotsa dropouts on this link
[16:26:12] <SWPadnos> close to $300 for the round trip, but it does save quite a bit of driving
[16:26:28] <skunkworks_> how long does it take to cross the lake?
[16:26:29] <SWPadnos> you're just one long day away though, so it doesn't save a hotel nigth
[16:26:32] <SWPadnos> night
[16:26:33] <skunkworks_> * skunkworks_ should google
[16:26:37] <skunkworks_> hmm
[16:26:43] <skunkworks_> I wonder if dad would like that...
[16:26:46] <SWPadnos> leaves at 11:00-ish, arrives at 5:30-ish
[16:26:49] <skunkworks_> he likes boats..
[16:26:55] <tom3p> the ferry is an adventure, old Canadian ferry, lousy times, cool tiny berth ( if prison cells were cool )
[16:27:11] <SWPadnos> hmmm. looks like that changed too
[16:27:40] <SWPadnos> 1:55PM- 6:55 PM now (including time change)
[16:27:49] <skunkworks_> wiw
[16:27:51] <skunkworks_> wow
[16:28:27] <SWPadnos> that's actually not a bad time, it still gives you the couple of hours you need to get from Ludington to Ann Arbor
[16:29:09] <Dave911> The cruise through Chicago isn't too bad since they finished construction on the south side along 80. That was a disaster for a couple of years.. I'd just drive through the big windy ....
[16:29:25] <Dave911> Just miss rush hour/s!
[16:29:35] <SWPadnos> it's 300 miles of additional driving in each direction
[16:29:45] <Dave911> No way ...
[16:29:47] <_TwisT_> So, is there any comments about "video drivers vs realtime"? Especially about vesa & nvidia & nv
[16:29:49] <SWPadnos> which is lots of gas $$$ in that big-ass pickup of theirs :)
[16:30:08] <SWPadnos> _TwisT_, nvidia proprietary drivers may cause bad latency spikes
[16:30:21] <SWPadnos> you should try them and see if the latencies are good enough for your purposes
[16:30:24] <_TwisT_> yep, I've already noticet that
[16:30:25] <SWPadnos> if not, try nv
[16:30:30] <SWPadnos> and if that doesn't do it use vesa
[16:30:39] <SWPadnos> hard to be much more specific :)
[16:30:41] <_TwisT_> [18:43:48] <_TwisT_> I've noticed, that response of a system slows down only at init and shutdown of 3D-acceleration (for example, opening and on closing of glxgears), but works smoothly while OpenGL context is running (I've used an "reset" button in latency-test just after glxgears launch)
[16:31:32] <Dave911> Skunkworks - are you in Lacrosse, WI
[16:31:49] <skunkworks_> yes
[16:31:55] <SWPadnos> if you can stress the system and still get OK latency numbers, and you can guarantee (to your satisfaction) that no GL contexts will be created/destroyed while you're machining, then I think you can answer the question
[16:31:59] <SWPadnos> (with a yes, it
[16:32:03] <SWPadnos> it's good enough)
[16:33:08] <_TwisT_> SWPadnos: ok, cool. BUT.... EMC is not working... Just crashes with an error (one moment...)
[16:33:19] <Dave911> That's what I thought ... what about 10 hours from Lacrosse to Ann Arbor through chicago .. ?
[16:34:24] <KimK> tom3p: The bike map only has Ypsilanti as the dorm address, don't you need more to get a proper map location?
[16:34:41] <SWPadnos> aren't the dorms on the campus?
[16:34:46] <Dave911> My sister takes the ferry from Wi to Ludington each 4th of July .... but she parks her car on the WI side... My parents pick her up in Ludington .. putting the car/truck on the ferry is the killer
[16:34:51] <SWPadnos> so you'd use a campus map to see where to go
[16:35:12] <SWPadnos> Dave911, it didn't seem so bad when we did it a few years ago
[16:35:20] <Dave911> Eastern MI is east of the Workshop location
[16:35:21] <SWPadnos> they drive all the vehicles on and off the boat
[16:35:42] <KimK> SWPadnos: tom3p just posted a link to a Google bike map that shows 4.3 miles away, but I'm having doubts about it.
[16:35:47] <Dave911> Oh yeah ... it is the upcharge for the car .... I meant
[16:35:51] <SWPadnos> and you have to wait for them whether you have one or not :)
[16:35:58] <SWPadnos> yeah, $70 each way
[16:36:02] <Dave911> Right ....
[16:36:38] <Dave911> I thought it was more than $70 each way ... now that doesn't seem so bad for some reason ...
[16:37:07] <SWPadnos> http://www.ssbadger.com/content.aspx?Page=schedule
[16:38:50] <tom3p> better map from dorm to workshop (3dorms on E side of campus) http://tinyurl.com/24re3br
[16:38:51] <_TwisT_> SWPadnos: here is my error: Unexpected realtime delay; check dmesg for details
[16:39:06] <SWPadnos> yes, that's to be expected
[16:39:07] <MattyMatt> 4.3 miles is Ok if it's flat
[16:39:16] <SWPadnos> since AXIS starts up a 3D context for the preview
[16:39:24] <tom3p> if i go, i pack the ebike :)
[16:39:30] <MattyMatt> even with a mill on the trailer
[16:40:01] <MattyMatt> for Show and Tell :)
[16:40:02] <_TwisT_> SWPadnos: can I skip that tests? :(
[16:40:09] <Dave911> It is pretty flat
[16:40:10] <SWPadnos> you should be able to load up the latency-test HAL module with your emc2 config, and monitor that for spikes
[16:40:28] <SWPadnos> no, but it's not fatal, it just tells you there may be a problem and moves on
[16:40:41] <tom3p> KimK I'll have to call and find out about cooking, parking & lockout hours ( college campus curfews ) ooh and about inet access too
[16:40:53] <_TwisT_> this *is* fatal
[16:41:02] <SWPadnos> it shouldn
[16:41:06] <SWPadnos> it shouldn't be
[16:41:08] <_TwisT_> :((
[16:41:33] <Dave911> Wow, I thought the passengers were cheaper and the cars were more $ on the Badger... seems just the opposite now ..
[16:41:42] <_TwisT_> EMC just shutting down next moment after startup
[16:42:02] <SWPadnos> run emc from a terminal, and put the full text of the terminal session on http://www.pastebin.ca
[16:42:58] <_TwisT_> SWPadnos: ok, I'll do it tomorrow (not at work now)
[16:43:02] <SWPadnos> ok
[16:43:11] <_TwisT_> thanks
[16:43:31] <SWPadnos> the latency message shouldn't be fatal, so there's got to be something else going on
[16:43:33] <SWPadnos> sure
[16:44:35] <tom3p> KImK campus map with dorms http://www.emich.edu/maps/ (and see ^^^ is for specific map from dorm to workshop )

[17:42:14] <sealive> there are still more
[17:58:33] <Dave911> skunkworks_: Hmmmm... A good example where ignorance is shown *not* to be bliss......
[18:00:17] <sealive> most way work the way they shoudt work a 5Tonn Zaxis diven from L297/298 is not the way to do it
[18:26:00] <fragalot> perfectly possible to drive a 5ton Z-axis with just a 298 chip
[18:26:09] <fragalot> it'd just take *AGES* for it to move
[18:26:10] <fragalot> :P
[18:28:15] <Endeavour> Hello
[18:28:49] <fragalot> hi
[18:36:14] <bricofoy> hi
[18:38:30] <frallzor> story
[18:38:48] <fragalot> listening.
[18:38:53] <fragalot> but not really
[19:04:50] <frallzor> yeay i killed my fuses to my comp today
[19:05:17] <fragalot> congrats?
[19:05:29] <frallzor> now I cant mill until tomorrow :P
[19:05:50] <fragalot> oh that type of fuses
[19:05:58] <fragalot> * fragalot dies a little bit every time he sees one of those
[19:06:09] <frallzor> no idea on what the value was though
[19:06:14] <fragalot> what colour are they
[19:06:17] <frallzor> got a 1A and it fried instantly
[19:06:19] <frallzor> glass
[19:06:35] <frallzor> then I noticed the PSU wants 1.8A in
[19:06:39] <skunkworks_> they should say on the metal ends..
[19:06:41] <frallzor> so that wasnt unecpected then
[19:06:42] <fragalot> should be printed on there
[19:06:50] <fragalot> if not on the metal ends, on a piece of paper inside of the glass.
[19:06:53] <frallzor> wasnt on these
[19:07:00] <fragalot> or on the fuse socket
[19:07:02] <frallzor> just said 1L250V
[19:07:18] <frallzor> nothing about A
[19:07:40] <fragalot> neat
[19:07:57] <frallzor> so i need at least 2A
[19:08:44] <fragalot> not 'at least', you need the right fuse
[19:08:48] <fragalot> if it blew, it blew for a reason.
[19:10:01] <frallzor> +0.5A for the lcd it seems
[19:10:20] <frallzor> It blev because I was lazy and tried to turn the main switch on with a stick =)
[19:10:36] <frallzor> I "sparked" it a few times
[19:10:41] <fragalot> how did yuo manage to blow a fuse by flicking a switch? :P
[19:10:42] <fragalot> oh
[19:10:45] <fragalot> nice
[19:11:02] <tom3p> we had a guy in service, blew up the 3 phase mains fuses while installing a machine, so he put in bigger, blew up the transformer... they made hi west coast service manager :P
[19:11:37] <frallzor> I guess the fuses in the comp was just 2.5A
[19:11:43] <frallzor> not much room to spare for spikes
[19:12:10] <fragalot> the PSU wasn't really designed to have spikes :P
[19:12:31] <frallzor> they are, but not fuses
[19:13:23] <frallzor> hopefully itll kickstart with new fuses, then ill start walking to the breaker :P
[19:13:42] <SWPadnos> tom3p, better for him to be in management where he can't blow things up ;)
[19:13:49] <fragalot> xD
[19:14:17] <fragalot> I've made the mistake of listening to a company manager once wrt the line voltage they had coming in
[19:14:27] <fragalot> he told me 220V so hooked up the machine transformer accordingly
[19:14:30] <tom3p> SWPadnos, that was exactly the idea
[19:14:31] <fragalot> *Poof*
[19:14:43] <fragalot> "Oh right, we got switched over to 400V last month"

[20:02:30] <davidf> SWPadnos, Hi, I have a 15 ppr encoder on A phase, and Index on Z, Set ou via the config wiz.
[20:02:51] <davidf> *set up
[20:03:05] <SWPadnos> ok, and no B connection?
[20:03:14] <Srpski> Srpski is now known as Dannyboy
[20:03:25] <davidf> I changed position to position.interpolated
[20:03:34] <davidf> SWPadnos, no B yet
[20:03:40] <SWPadnos> and set it to counter mode for now then
[20:03:50] <SWPadnos> otherwise it thinks the encoder keeps reversing
[20:03:58] <SWPadnos> and only moves one count
[20:04:06] <davidf> I loaded the pyVcp tach widget, it works.
[20:04:34] <SWPadnos> ok
[20:04:43] <davidf> Not clear on your last?
[20:04:57] <SWPadnos> if it works right, nevermind. it's probably set up correctly
[20:05:06] <SWPadnos> is there a question in there somewhere?
[20:05:11] <SWPadnos> (other than mine)
[20:05:13] <davidf> Well, after a fashion...
[20:05:17] <SWPadnos> (asking about questions) :)
[20:05:38] <davidf> The speed displayed in the tach jitters a bit, about 3 to 10 percent.
[20:05:54] <SWPadnos> at what motor speed?
[20:06:02] <davidf> all.
[20:06:11] <davidf> from 0 to 2200
[20:06:15] <davidf> RPM
[20:06:32] <SWPadnos> is the pyvcp tach connected to a ddt or the encoder velocity output?
[20:07:11] <davidf> encoder.velocity I think.
[20:07:42] <davidf> Is there an encoder.avg_velocity or similar?
[20:07:51] <SWPadnos> no, but you can make one
[20:07:58] <SWPadnos> there are various filter components in HAL
[20:08:24] <SWPadnos> get a halscope plot of position and see how linear that is
[20:08:45] <SWPadnos> gotta run for a bit
[20:12:20] <davidf> thanks, bbl.
[20:18:05] <Jymmm> Do all smaller generators use brushes, or only the cheap ones?
[20:41:13] <davidf> SWPadnos, Are you back now?
[20:43:56] <davidf> Can somebody explain how to properly set the scale factor in the pyvcp tach widget for axis please?
[20:45:13] <KimK> Jymmm: generators as in tach generators?
[20:45:37] <Jymmm> As in 3000W 120VAC gas generator
[20:45:55] <JT-Work> davidf: the pyvcp dial widget?
[20:46:17] <davidf> I was using a bar type but whatever.
[20:46:34] <JT-Work> ok what is the question?
[20:47:24] <JT-Work> the bar widget doesn't have a scale pin AFAIK
[20:47:39] <davidf> The scale factor parameter expects a number. What is the significance of that number as far as how the speed is interpreted and displayed?
[20:48:22] <KimK> Jymmm: Ah. Probably yes, brushes, then, for the field current, unless the generator is *very* small (permanent magnet only)
[20:48:26] <davidf> my lathe spins at anywhere from 0 to 2500 RPM
[20:48:34] <KimK> brb
[20:49:01] <JT-Work> ok, your hooking up a spindle tach
[20:49:19] <davidf> yes, a 15 hole encoder.
[20:49:35] <davidf> A phase and index.
[20:49:55] <Jymmm> KimK: k, ty
[20:50:11] <davidf> It is just that there is this scale number that I don't know how to set.
[20:50:45] <davidf> It was set to 100 by default, and that caused the displayed speed to vary from 0 to 0.9
[20:50:58] <JT-Work> scale for the encoder component?
[20:51:29] <davidf> then I "intuitively " set that number to 0.006 (15/2500) and now it displays 0 to 2213
[20:51:55] <davidf> scale in the xml file that makes the tach\
[20:52:40] <Dave911> Jymmm Brush generator heads are cheaper than brushless ..... but you can buy both...
[20:52:47] <JT-Work> ok that is the scale component
[20:52:48] <davidf> there is a param for max (set that to 2500) and a param for scale. But no docs on either.
[20:52:53] <Dave911> I've never had a problem with a brush generator
[20:52:55] <JT-Work> http://www.linuxcnc.org/docview/html//man/man9/scale.9.html
[20:53:38] <JT-Work> davidf: all the components are in the man pages or on line except for the more complex ones that are in the docs as well
[20:53:45] <Jymmm> Dave911: Well, this one I was considering has brushes, but I found out it only has a 2.2hr @ 50% runtime on the tiny tank, so nevermind =)
[20:54:31] <Jymmm> I guess I'm just going to save my pennys for a Honda EU2000i
[20:55:13] <Dave911> There was/is a 2000 watt genny at the local tractor supply for $150 - 4 stroke and all.... super cheap
[20:55:51] <Dave911> The Champion 3500 watt gennies are very popular with the RV crowd
[20:55:53] <JT-Work> davidf: can you pastebin the file I'm having trouble figuring out where you are
[20:57:05] <Dave911> JT-Work.... Isn't there a pyvcp example with a bar on it ... or no that was a dial for the spindle RPM?
[20:57:10] <davidf> just a min...
[20:58:20] <frallzor> PSU and MOBO checked, alls semms fine, nothing seems popped besides external fusing
[20:58:51] <Jymmm> Dave911: How are those types of generators on things like household frig/freezer or window air conditioners?
[20:59:22] <Dave911> I think they are fine...
[20:59:51] <JT-Work> Dave911: the only example I see is with the GS2 and the dial widget
[20:59:59] <davidf> JT-Work, No, I was wrong. It isn't part of the custompanel.xml file. I have to go look. The computer isn't online and it's in the shop.
[21:00:11] <Jymmm> Dave911: Well "think" dont work if it blows out the compressors =)
[21:00:12] <JT-Work> ok
[21:01:19] <Dave911> Jymmm... you do know that brushless generators are relatively new ... before that all generators were brush..
[21:02:31] <Dave911> I loaned my 6 kw brush genny to a friend who powered his house off of it for 10 days two years ago ... nps
[21:03:34] <Jymmm> Dave911: That Champ3000 is 100lbs + 32lbs for a full tank. That in itself isn't a biggy, but it's just bulky and would be hard to lift into a truck.
[21:04:02] <Dave911> Where you can get into trouble with AC/refrig compressors is when you don't have enough power to start them up cleanly.. IE don't try running your central air off a 3 kw genny etc.
[21:04:07] <Dave911> Ramps
[21:04:57] <Dave911> My 6 kw unit is 200+ lbs - I don't lift it.. A hand truck or platform with casters works well
[21:06:04] <Dave911> I'd love to have a Honda 3500, but I'd rather take a vacation... :-)
[21:06:08] <Jymmm> I like the fact that two of the Honda Eu2000i can be connected in tandem to (alomost) double the power.
[21:06:25] <Jymmm> and each is still only 46lbs
[21:06:52] <Jymmm> and quiet as hell
[21:07:09] <davidf> JT-Work, It's in my minilathe.hal file. The line in question is setp encoder.o.position-scale <some number>
[21:07:27] <davidf> Question is, what number?
[21:07:53] <Dave911> Still about $2K for two of those .... I can stand some noise for the difference ... plus when the power goes out everyone else will have their genny running also - so much for quiet :-)
[21:08:01] <davidf> number of pulses per rev? or what?
[21:08:09] <JT-Work> how many pulses per revolution on your spindle?
[21:08:11] <JT-Work> yes
[21:08:14] <davidf> 15
[21:08:34] <davidf> OK
[21:08:52] <Jymmm> Dave911: It was more the convience of moving it that I liked
[21:09:17] <JT-Work> davidf: http://www.linuxcnc.org/docview/html//man/man9/encoder.9.html
[21:09:31] <JT-Work> encoder.N.position-scale float i/o
[21:09:35] <JT-Work> Scale factor, in counts per length unit. For example, if position-scale is 500, then 1000 counts of the encoder will be reported as a position of 2.0 units.
[21:09:54] <Dave911> JT: FWIW ... Here is a bar example for the xml code .... http://unpy.net/emc2-docs-new/hal_vcp.html#r1_5_6
[21:11:35] <SWPadnos> davidf, I'm only here for a sec, but remember that 15 will give you RPS, not RPM
[21:12:12] <SWPadnos> 15 counts is 1 revolution, which is correct, but you need to scale that number by a factor of 60 to get RPM (for the tach display)
[21:12:19] <Dave911> Jymmm.... anymore and I don't even like to horse around 46 lbs... I wrenched my back bad one time spinning around with a 40 lbs bag of salt ... felt that for weeks. Better off grabbing a hand truck IMO... Of course I just put up 6 pieces of siding on my garage - 50+ lbs each .. so I break that rule a lot apparently
[21:13:06] <JT-Work> Dave911: that's pretty similar to the one in the manual
[21:13:53] <Dave911> Hey.. it is off of Jeff's website :-) I didn't even notice that...
[21:13:57] <Jymmm> Dave911: Well, I DO have one of these http://www.harborfreight.com/24-inch-x-36-inch-folding-platform-truck-3377.html as well a one of thse heavy duty 2/4 wheel convertable hand trucks http://www.harborfreight.com/24-inch-x-36-inch-folding-platform-truck-3377.html
[21:14:08] <davidf> so scale should be 15 / 60 = 0.25 ?
[21:14:18] <SWPadnos> no
[21:14:26] <davidf> 15 * 60?
[21:14:32] <SWPadnos> possibly
[21:14:48] <davidf> Now I'm laughing. :)
[21:14:52] <JT-Work> if your using encoder.N.velocity float out it is Velocity in scaled units per second.
[21:14:53] <jay_> jay_ is now known as fjay
[21:14:53] <SWPadnos> I don't remember if the motion controller needs to get RPS or RPM spindle feedback, I think it's RPS
[21:15:12] <SWPadnos> in which case you definitely want the scale to be 15
[21:15:30] <JT-Work> davidf: you just want your tach to read correctly?
[21:15:37] <davidf> yes
[21:15:39] <Jymmm> bbiab
[21:15:40] <SWPadnos> you can then add a "scale" component to your HAL setup, to multiply the number by 60 for display in the pyvcp widget
[21:15:48] <JT-Work> there you go
[21:15:52] <Dave911> Jymmm: those work fine.. I have a fold down handtruck that converts into a platform that I use a lot also .. moving 100 lbs on that is simple ... Get a couple of 2x12's 8 feet long to roll it up into your truck...and you are set.
[21:16:06] <SWPadnos> the pyvcp widget shouldn't have a scale pin/param, but it should have high and low limits
[21:16:12] <SWPadnos> or range
[21:16:41] <davidf> Wepyvcp custom.xml has a max value.
[21:16:54] <davidf> pyvcp I meant
[21:17:01] <SWPadnos> the trick is that you need to have both RPS and RPM for different purposes, so you need to set up the encoder to give RPS and then multiply to get RPM
[21:17:43] <davidf> And send that multiplied number to the pyvcp tach?
[21:17:49] <SWPadnos> yes
[21:18:32] <davidf> I'll have to study up more. Even that simple thing is beyond me at this point.
[21:18:48] <davidf> I really ned to rtfm
[21:19:06] <SWPadnos> loadrt scale
[21:19:18] <SWPadnos> setp scale.0.scale 60
[21:19:20] <SWPadnos> (I think)
[21:19:35] <SWPadnos> etc etc. bbl
[21:26:39] <odiug> Has somebody got the "Single button probe" from ClassicLadderExamples running?
[21:39:17] <JT-Work> * JT-Work heads to the house to do some roofing work in the 90° heat
[21:55:02] <Dave911> JT-Work: Feeling a little masochistic today?? I have 20 squares of two layers to tear off and put down still. If it ever stops raining up here I might get to it... but then it will be 90 like it apparently is down your way. Gotta go paint some siding - rain tomorrow again...
[22:05:26] <jthornton> Dave911, I just need to get the roof patched where a tree fell on it
[22:06:44] <jthornton> davidf, you get the tach working?
[22:17:44] <pfred1> I got my lead screws and bearings
[22:33:29] <Jymmm> * Jymmm is back!
[22:35:09] <Jymmm> Dave911: Paint siding??? Isn't that one of the reason for getting siding is so you dont have to paint?
[22:36:30] <Jymmm> I saw some new roof tile the other day on tv, it's a galvaluminum base - can withstand 140MPH winds
[22:37:03] <pfred1> for how long?
[22:37:17] <Jymmm> it's warranty is 50 years
[22:37:38] <pfred1> oh I don't htink it'd withstand 140 MPH winds for the whole 50 years
[22:38:27] <Jymmm> I dun know, looked pretty good to me. It all interlocks and is screwed down
[22:38:42] <pfred1> wind is funny that way it takes a bit sometimes to really do the damage
[22:38:46] <Jymmm> not ust overlapped
[22:39:23] <Jymmm> and it looked like every other roof too, so nice to blend in
[22:41:44] <pfred1> sustained 140 MPH winds is enough to lift whole roofs off intact so sure your tiles will be fine
[22:42:01] <pfred1> too bad they'll be about a mile from your property though
[22:42:22] <Jymmm> Well, if there is no roof, the tiles are the least of our worries.
[22:42:25] <Jymmm> your
[22:42:31] <pfred1> yes indeed
[22:43:01] <pfred1> last thing I'm worried about in sustained 140 MPH winds is will my roof tiles be OK?
[22:43:23] <packrat> so, if #EMC is enhanced machine controller, where is the channel for electromagnetic compatibility?
[22:43:34] <kanzure> ##electronics ?
[22:43:46] <Jymmm> packrat: #magnetics
[22:43:47] <packrat> bah, thats too easy
[22:43:49] <pfred1> packrat are you feeling positive or negative today?
[22:43:57] <kanzure> positively negative!
[22:44:09] <packrat> im feeling like an ionic breeze
[22:44:28] <packrat> (i know, that made no sense)
[22:45:20] <pfred1> I think the DEA should bust VXB.com they got to be doing something over there than just shipping bearings
[22:45:51] <pfred1> I swear the bearings were here almost before i hit the send button on the order
[22:46:14] <Jymmm> pfred1: and the problem is?
[22:46:32] <pfred1> well just so long as my shipping charges aren't sky high
[22:46:59] <pfred1> but i got the distinct impression that htey must have the most sicked pack and ship plant on the planet
[22:47:15] <pfred1> like they must have ball bearing floors or something
[22:47:40] <pfred1> seriously from CA to DE less than 2 days?
[22:47:52] <pfred1> and i picked the ground option too
[22:48:02] <Jymmm> Priority mail?
[22:48:14] <pfred1> yeah it was regular USPO
[22:48:40] <pfred1> no i was stunned by how fast I got the stuff
[22:48:44] <Jymmm> Yeah, I've shipped at 1pm and was received on east coast at 11am once
[22:49:11] <pfred1> enco took a bit longer to get their junk to me
[22:49:11] <Jymmm> Yeah, ppl give the USPS a lot of shit, but they are really not that bad at all, unless you're in the midwest
[22:49:40] <pfred1> enco used UPS
[22:50:15] <pfred1> well the order before the dopy post person didn't just leave the package i had to go to the post office to pick it up
[22:51:03] <pfred1> UPS is good that way they'll leave gold bricks on your front stoop
[23:02:44] <pfred1> even though I've still no complete plan as to just how I'm going to build my machine getting these orders still has got me excited over here
[23:03:03] <pfred1> * pfred1 is seeing pieces parts piling up
