SkinnYPup: I was talking about the german one
it puts a postproc config file in your home directory
guess I will have to convert it. I can't get it to read a tape or the serial port.
cradek: what kind of machine?
I think its an HNC lathe
completely off topic - blue heron photos: http://jmkasunich.com/cgi-bin/blosxom/index.html
you are sure good at that.
I shoot a _lot_ and only show the good ones
shot about 100 today
that's a good strategy
the bee shot wasn't as hard as it looks - the bee was dead and sitting there
was it hot there today too? I saw 109 today (but I didn't believe it)
no - quite pleasant really
maybe 80, but not too humid
65 now - nice sleeping weather
still 90 here - nice air conditioning weather
good basement project weather
A few hours earlier, SkinnYPup and DanielFalck were talking about a Windows DXF to g-code converter at http://dxftogcode.googlepages.com/dxf2gcodedxftogcode
. For the record (and in case anyone is still up), I tried installing it under Wine (0.9.59, Ubuntu 8.04). I right-clicked once to install it ("open in Wine") and again to run it (Start/Wine/Browse C:\Drive) It seems to be working. No one is more surprised than me!
KimK: Thanks for pointing out it will run with wine. I might take it for a spin.
SkinnYPup: You're welcome. How did you find this thing in the first place, just Googling? It seems to be tailored for plasma/flame cutting but 2D X/Y can still be very useful.
It was off the EMC wiki I'm pretty sure, Just didn't realize there were TWO dxf2gcodes

The easy install reminds me of that sheet listing things that engineers say and the layman's translaton of them. Engineer-speak: "Initial test results have exceed our expectations." Layman's translation: "It Works! And are we surprised!"
exceed -> exceeded
I just installed sheetcam that BigJohn had mentioned , bit late but figured I'd scan over the help for a few minutes
how do you identif P/I/D settings on a drive?
what pot does what?
increase one and watch the signal?
anonimasu: usually yeah
how many pots?
don't they have any names/letters on them?
on the amps I usually work with I have: acc. current limit, normal current limit, gain, offset, tach amp., ..
alex_joni: I have 3 I think + offset
alex_joni: I'll scan a paper of the amp.
I have been experimenting with a usb parallel converter, are there any quick start guides for a newbie to interface new hardware with emc2?
and the manpages in emc2-dev for the rtapi and hal functions. but writing an emc2 interface for a usb device is not a newbie task. At a minimum it will require an extensive understanding of the USB protocol and the details of USB interface hardware.
or you don't expect much from it, and run it in userspace (without RT)
it might be enough for toggling bits once in a while (flood or coolant might be ok for this)
I hoped there would be some sort of api that step data could be piped out to?
I did some quick experiments on the console "echo -e '\ooo' > /dev/usblp0" and toggling bits steps the motors
obviously the realtime syncronisation and functions would not be used
mung: the problem is that USB sends packets every millisecond or so
so you get crappy step rates
there is a USB-RT somewhere
but I didn't look into it very much
how come?, i thought usb was 480Mb/s, must be huge data packets???
if i had a calculator i could work out if that guess was right?
it sends big packets, but only every 1 msec
1000 millisec / 480 thousand kbytes ???
you can also get some DMA transfer set up so that it has high bandwisth
but I don't think you can assemble lots of packets to send
I think I said this yesterday, I will look into further and maybe come back later if I find anything
A high-speed transfer can request up to three 1024-byte packets in each 125-microsecond microframe, which works out to 24.576 Megabytes per second. An endpoint that requires more than 1024 bytes per microframe is a high-bandwidth end-point. A full-speed transfer can request up to 64 bytes in each 1-millisecond frame, or 64 kilobytes per second. And a low-speed transfer can request up to 8 bytes every 10 milliseconds, or 800 bytes per second.
mung: that's the good part.. the bad part is:
The endpoint descriptor stored in the device specifies the maximum latency. For low-speed devices, the maximum latency can be any value between 10 and 255 milliseconds. For full speed, it can be anywhere between 1 and 255 milliseconds. For high speed, the range is from 125 microseconds to 4 seconds, in increments of 125 microseconds (the width of a microframe).

jepler: I'm using a sim version of axis (run in place) and want to play with python poking around at axis/emc. I am looking at my old notes (11/27/2007) and have tried >>>import emc from python and "have no module emc". What should I look for in this system? thanks
DanielFalck: before you can do that, remember to ". scripts/emc-environment"
I'm using axis as a simulator, launching it from gedit.
I bet you could then strip half of it away, and only use the 3d preview
I have gedit running crotchetyGuy's apt/sketch program and axis verifying the gcode
with the gedit plugins I can hit a hot key and have the gcode generated
so, now I want to control axis from gedit to start the program or reload the program, tooltable etc
fun stuff : )
there's also "axis-remote"
cool- tell me more
which I believe is meant for remotely controlling axis
uh - man axis-remote? :)
it is there : )
sure (I don't know anything more than that ;) )
DanielFalck: axis remote is in the manual also
the pdf for sure
it is a sub of the Axis chapter
