who compiles kernels and doesn't know 'lsmod'?
well that's an interesting question
curses on all things cheap and chinese!
smoke came out of a motor run cap
curses on single phase motors and their horrid caps while I'm at it
last time it was startup current blowing a fuse (mill motor)
this time it was running current letting the foul smelling smoke out of the cheap ass run cap
(running the lathe at the moment(
can you just put a better motor on it? I'm sure you have one in your piles of dumpster stuff...?
actually I don't have any single phase motors laying around
besides, just about all single phase motors use caps of some sort
there's not really another good way to get a rotating magnetic field (need some phase shift from somewhere)
induction motors ? not a good way?
I'm talking about induction motors
a single phase stator without caps or other tricks will give a field that flops back and forth rather than rotating
oh, i forgot they have a little cap with a centrifugal switch
to get started
in this case, two caps, one large one for starting, and another for running
* alex_joni wonders if run-from-line should work with G91 (relative coords)
* jepler wonders if run-from-line works for any interesting cases
what do you mean work with?
cradek: a user reported that he has a file with relative coordinate moves (I think that's G91)
it works fine running it from the beginning, but run-from-line only gives him a ferror
ferror? no matter what junk the interpreter spews out its canon interface, it shouldn't lead to a following error
jepler: I thought so too.. and I can't rule out a user-error
or there could be two problems
I get the impression that, again, you don't have a real bug report here
last night someone reported a jfe when running the axis splash screen in stepper_mm
I found an interesting behavior of cutter comp. I don't know if it's a bug
hm, surprisingly to me I was able to start the home sequence (homing "Z") while on the X limit switch
I think I hit L F2 Ctrl-Home
hmm, I wonder if that's a feature
speaking of homing
what determines if there is a "Home Axis" or "Home All" button on Axis's manual tab?
anyway the surprise about that comp code is that it changes if you use g0 vs g1 for the entry
presence of a homing sequence in the ini
thats what I thought too
lathe: I have home sequence 0 on one axis, nothing on the other, I get home all
then home all will only home that one?
mill: I have home sequence 0 on Z, seq 1 on Y, and nothing on X, and I don't get home all
(why do you have that?)
you might have to rtfs
the saddle axis (Z on lathe, X on mill) doesn't have a switch
maybe it only checks one of them or something
widgets.homebutton.configure(text=_("Home All"), command="home_all_axes")
homing_order_defined = inifile.find("AXIS_0", "HOME_SEQUENCE") is not None
jepler is faster at both rtfs and rtfm
well, he knows where to look in Axis
btw, whoever wrote file reload - that is a great feature
for this keyway, I wrote a prog that had #vars for several params like the depth to start and stop
I could set them, load the program, run it, measure the result, and set them again for another pass
alt F R and start the next pass
even ctrl-R I think
I used to avoid keyways like the plague
even this one probably took a half an hour
but its done and nice
it's no secret that I think AXIS is pretty decent :-)
cradek_ is now known as cradek
the error is still there, around line 1196
* alex_joni agrees
it's less emc specific though
maybe it doesn't work?
although I'm sure I got it recently
version 1.58 (latest I think), line 1196 is the last line of the file
I'm still not used to vim
oh, I bet I know why he didn't see the message
(maybe, lemme check something)
jepler broke it
[19:44:08] <jmkasunich> http://cvs.linuxcnc.org/cgi-bin/cvsweb.cgi/emc2/configs/common/core_stepper.hal.diff?r1=1.10;r2=1.11;f=h
the sample configs no longer set the maxvel parameter at all
I guess I'm the evildoer here
ok, my config was old and still did that
it was probably an attempt to reduce the cruft in the ini file
and I probably told you that maxvel isn't used, only maxaccel is used (for the "pretuned position loop" stuff)
jepler I hate you
what did I do? can I still fix it?
you posted your experience with pwmgen and servomotors (etch-servo)
xemet saw it and tried to copy it, but he is lacking in clue
I've been trying to help him for the last hour or so, and its painfull
you understand that I only mean to do good by sharing things like this on the web, right?
I know, I was joking
that said, I feel your pain and I'm sorry I caused it
things on the web should be labeled with a "tinkerer level"
if your tinkerer level is much less than the project level, you should skip it
if only slightly lower, then try it but be very meticulous - and if you succeed, yay, you've raised your level
xemet needs to start with soldering, using a meter, basic troubleshooting (its going in this end of the wire but not coming out the other)
as opposed to going in one ear and out another?
his enable signal is flakey
I was gonna try to walk him thru tuning (after spending half an hour chasing a ghost problem), but as soon as he powered up the motor started going at full speed
halcmd showed everything inside OK, so I told him to meter the parport and then the L298 pin
they didn't match, one was 0V, the other 0.8 (both low, so it should work)
then he said "I used a little brush on the driver and now it is 0.2V and works ok"
dirty or bad solder joint maybe
but I'd think enable open would still be off
the datsheet trumpets the part's LOGICAL "0" INPUT VOLTAGE UP TO 1.5V (HIGH NOISE IMMUNITY)
WHY IS IT YELLING?
because it thinks the reader might have SIGNAL IMMUNITY?
anyway .. not that it has much bearing on the more general problem
xemet just found an "interrupted cable"
I need to hook up pluto-step to my stepper board -- I finally got some of these, which will let me adapt the pluto pinout to the xylotex without making a board or hand-rewiring an idc cable .. http://www.sparkfun.com/commerce/product_info.php?products_id=8430
I like your idea of a 'tinkerer level'
geek social fallacy says that everyone's level is about like mine (actually I figure that since I only started on electronics a few years ago everyone else knows a lot more than me)
cradek: now we need some authority to impose it :)
jepler: for any technical topic about which a person knows anything, they know vastly more than 95% of humanity
I think it's sad :)
axis question - can you set the incremental jog increments in the ini file?
xemet is using mm, and 0.1 is pretty small
simple matter of rtfm
how would he set a 1mm increment?
(I'd have to look too)
I've spent 2 hours with him so far, and my patience is wearing thin - you are supposed to know everything about axis
% grep -r INCREMENT .
./dallur-thc/dallur-advanced.ini:INCREMENTS = 1000 10 1 0.1 0.01
./sim/axis_mm.ini:INCREMENTS = 1 mm, .01 in, .1mm, 1 mil, .1 mil, 1/8000 in
dallur has 1000mm which seems like one hell of an incremental jog
maybe it's inches?
I've noticed you can't have a separate increment setting for rotaries - that would be nice
0.1 inches is pretty big, but 0.1 degrees is small
