ack - brain age 34 and then 51
26 from the one and only time I tried it
I didn't find anything interesting about the 'puzzle'
its not a puzzle
its a memory test
someone was asking for raster laser plot via gcode.
they assumed gcode would do it if they could get the conversion.
best check that synchronized laser on-off gets acceptable results. may need exact stop mode.
I had a little time to make a pic program to output a square wave into the h-bridge. At really low current - I can see the current limit working - it trips - stays low until the next rising edge. (cool) as I increase the current limit - it starts to oscolate at the 400khz range. (when tripping the current limit). I hope to dig deeper this weekend.
is that current sense resistor wirewound?

ok - I played a bit - thru the proccess of elimination - I was disabling the enable (setting the pin at the flipflop high so it isn't going thru the logic) setting other gates low or high so there was only a few paths..
looks like the noise is getting into the first gate (between the opto and the inverter)
a .001uf cap across the output of the op-amp to ground seems to make it stop for the current I was testing.
sorry - not op amp (I am getting tired) output of the opto isolator and ground
if that made sense.
some optos only need a few uA to trigger - could hte noise be getting into the input side of the opto?
I think these optos need a brick to turn them on.
oh well - time for bed. I am happy :) (so far) felt good to get back into this again.

I am trying to find some information with regards to setting up my lathe with a spindle index signal that I can cut threads
there are some examples on the wiki
i set up everything via stepconfig and i get the spindle speed panel on the left hand side of the axis window but when I connect my encoder i do not get any reaction is there something else that i need to do
I have not used stepconf for setting up threading
you can check if data can be seen with halscope
I need to add a spindle encoder to my mill one day
i have the complete opposite problem when it comes to cnc's than most people that i have spoken to ,ie very limited electronics knowledge but very wide knowledge of programming and machining
a lot in here have a reasonable mix
Im an electonics engineer/programmer now working as a clockmaker
note with some encoders you need a pullup
do you have an oscilloscope
ok does the encoder signal change with rotation and does its voltage go above 3.3v and less than 5 for the high signal and down to 0 to less than about 1 for low
you need better string for your internet connection
I'm not sure if stepconf handles an encoder for the spindle
neil_macintosh: stepconf is a simple interface for creating a configuration, and only supports a very small subset of emc's capabilities
dunno if the par port can handle the datarate
it's fine for starting confings (simple one), but for more advanced stuff you want to get down & dirty and do it yourself
archivist that 4'th axis part is on its way to me!
good morning btw !
you could'nt wait for ally pally
i've been cleared by the missus to go to that if I want!
ally pally could be quicker than post, but the bits we got from chronos were quick enough and good enough
I have morse collets for the rotary centre hole
its MT2 init?
some I got from chronos and some locally from arc euro trade
mine is mt2
my spindle is mt2 as well so its all swappable about from blank holding to cutter holding
yeah thats a good idea, i'm mt3 throughout here
but i plan on bolting a chuck to the rotary table and leaving it on there
i could get rid of my dividing head once i have this rotary table
I made an adapter as its off and on
heh why not mod the dividing head
put dividing head on vertex 5axis !
hahh ah its not one with a handle to crank round
it has some notches and u can index it around in 15 deg lumps
perhaps dividing head is the wrong word
ah steam dividing
thats the older method boss uses
its this http://pjm.dyndns.org/lump.jpg
some of our lathes have something similar built into the headstock
this is made by marlco
Ok - I didn't know the camera wasn't focusing until after I was done.. But this is the pwm in and enable_not. http://imagebin.ca/view/oQ-Fyl2A.html
you get the drift I hope..
well - I guess it is just enable.
the taller trace is the enable. the smaller duty cycle trace is the pwm in.
focus? /me would separate for clarity
you can see the enable goes low at the right and then doesn't go high until the next rising edge of the pwm input
well - it would have looked a lot better if it was in focus ;)
totally different feel now.. no whistle when in current limit.
hmm dinner time /me should go fetch his new bubble for the clinometer
i cant idenitfy a pwm signal in that photo. are they overlapped? its an interesting idea to use the drive signal as the enable tho
skunkworks_: could be an I Ching reading for all I can tell
actually it's a fish .. you can see top of head, eyes, mouth, and flippers
(flippers are horizontal)
hah chines fortunetelling
sorry about that
the pwm signal is in the middle vertically - the enable is bigger
I must have put the camera in short focus mode by accident./
(I don't think I was awake this morning_
tektronix? post the printput?
no - b&k cheap scope.
and it is at home..
ah, hook it to hal and screenshot it :)
heh - hal isn't that fast... :)
get a digital scope

I wonder if you have my pcb design in it
do you have the terminal
yes we have the terminal, but there's a problem with loading the software, We're going to put an EMC2 controll on it =)
JanVanGilsen: how many axis?
hmm if it has a 6502 and djc on the pcb
6, iirc the puma 560 has 6 joints and the puma 550 has 5 (they both have written 500 on them[500 series])
JanVanGilsen, if scrapping the terminal then I would like the pcb for my history (I was an external subcontractor on the replacement pcb)
ok - I thought mine said 560 on it.. but I could be wrong
that is the way I understand it.
archivist, I'll still need to move the terminal home, then I can check if it has your pcb...
cool mechanics.. Lots of places to adjust the slack out of it.
ok thanks was a long time ago :)
please contact me via e-mail with a description where 2 look
I never had a complete terminal, only did pcb and software design
and got the prototype working
I will dig out the prototype and take a pic in the next week or so
I've got this:Unimation Visual Display Terminal Model 2D65568G01 Equipment Manual ...
I could scan you a copy =)
I had a spec to work to and an old pcb for outline
took me best part of a year to get paid
Is it possible to dynamicly change the home offset parameters via hal? The puma robot homes to the next index pulse and calculates the offset from the absolute position of a pot-meter.
same day different day?

jepler you see me
we all see you
i have one problem with emc228 and rtai
i have speack yesterday with jepler
ask clear questions so we can
i have istalle linux debian etch 4.05
better to use the live cd
i want compile the emc and on ubuntu not is possible
I compile on ubuntu
but on ubuntu more library for compile not is present.
there is a wiki page that tells you what you need to install
please send me the web addres for compile with ubuntu.i have install first ubuntu 8.04 live cd, but you command ./configure --enable run in place, more librury not present(G++, python.dev eccc.)

oh my - mach can only handle 10000000 lines of gcode.. ;)
entire lifetime of mach use?
That's the nail in the coffin.. I definatly using emc now. ;)
skunkworks_: found that out by personal experience?
you needed nails to change
fragalot: no - someone had mentioned it on cnczone.
[21:49:42] <skunkworks_> http://www.cnczone.com/forums/showthread.php?t=71138
has anyone tested emc for similar limits
I wonder what limits the number of gcode in mach
so, why would it then be a mach issue.
If i'm honest,... even NOTEPAD.EXE can't handle that much
(which is a really,... really sad example, to be fair)
skunkworks_: 10M ?
fragalot: notepad is one HUUUUGE POS
I'm not sure how they did it, but it seems they somehow managed to implement all the slowest possible algorithms
try replacing , with ; in a smallish (~400k) csv file
it'll take at least 10 minutes
alex_joni: yeah, and put exploits into wordpad.
pn is pretty ok
the AXIS preview will be useless far before 10 million movements, and maybe even when loading 10 million non-motion lines into the text preview.
I killed axis once with some bum gcode :)
bottom of my h-bridge is a 446kb file. 19305 lines
xemc copes just fine with a 1-million-line file with two motions and all the other lines just reading "n(some number)".. it takes about 10 seconds on my machine to run it
I've loaded a 60000 line file just fine
can even spin the preview nice and fast
That's nearly simular to saying "My compiler doesn't work, it's as if it's completely ignoring my comments"
(on my dual dual-core Opteron system with Quadro FX3500, in sim)
hmmm. actually, it may have been more lines than that. it's a 20M+ file
less | wc -l ;)
it runs this file at a few thousand lines a second: (echo g0 x0 y0 z0; echo g20; echo g64p.1 f100; seq -f "g1x[%.0f/100000]" 1000000; echo g0 x1; echo m2) > /tmp/big.ngc
it's more a matter of finding where the file is ;)
again in xemc
I was trying to remember the quicky line counter as well
650794: ERROR: Linear move on line 940313 would exceed joint 0's positive limit
heh I went from notepad which doesn't display the file correctly (no returns) to wordpad which I couldn't see a way to show the number of lines - to ms word which I ended up having to turn on line numbering and look at it in print preview.. jeeze
get programmers notepad
it lets you use either type of line ending and convert between them
hmmm. vim for Windows. novel
I use syn on windaz, it deals with either line ending type, but it does not like long lines much
and it's quite good
I noticed it
though "good" is more of a religious question ;)
it's an excellent implementation of vim
ah, ok then ;)
I still type vi, vim is to new fangled
