I gotta say, converting an atx power supply to a bench supply should be like the first electronics project anyone ever does. screw led blinkeys!
pc power supplies are designed for a base load, bench supplies can work down to 0 current
yea, that's why you put in a nice big resistor :)
although switch mode psu design has improved, some require some balance to the output loads
nobody but us chickens
Im at work
everybody must be lighting fireworks
someone around here is
I thought the house was falling apart
I haven't heard much this year
me either, until about 30 minutes ago
the 'police' have been patrolling extra - it is against the law to light fireworks in my little town
interesting. it was just legalized in Vermont a few years ago
out here in the wild west it is being restricted more and more
the Kansas legislature just lifted a LOT of restriction on firearm - pistols, rifles, shotguns and placed more restrictions on fireworks
there's no fireworks equivalent to the NRA I guess :)
oh there is
true gun control is the ability to - hit what you shoot at -
we can now own fully automatic weapons and short shotguns and rifles - licensed of course - but now legal
so people can shoot hte evil fireworks before they explode
LOL true - i want more guns!!!!
is there any news on joint constraints in addition to axis constraints?
I don't think so
I talked with cradek at the workshop about it. We just had one short conversation. He said he thought some work was being done.
there was some work done, but I think we didn't get as far as we had wanted
I finally have the cinci ready. The gear change component is working very good. The spindle is working very good. I started collection data today for lead screw compensation. I will be working on that in the morning. I will be able to comp A and B but I will have to wait until next week to comp X Y and Z
are the constraints something that can be worked on a little at a time or is that something that needs focused attention?
I think it's a big change that has to be done at once, then more can be added later
ie, there's infrastructure that has to change, then maybe features can be added or tweaked
watching the tool cone move in five axis motion in the axis interface is pretty cool
At Fest I told everyone I knew the solution to the constraints problem, but then I discovered my math wasn't up to it
did I read somewhere that EMC2 could use information in a gcode comment line?
it's possible, and done for several things
somebody is lurking - good evening jepler
how's things in wichita? they are exploding here.
but you'd need to add more things if what you want isn't already there
real quiet here - i think my wife and I will go downtown around 9:30 to see the show
swpadnos - duh
I learned today that there are a few AXIS directives, and I knew about MSG, LOG, DEBUG (?), and maybe PRINT
SWPadnos: what I was talking about earlier are some comments that AXIS treats specially when generating a preview: (AXIS,stop) to stop generating the preview, and (AXIS,hide) and (AXIS,show) to skip part of the program in the preview.
er stustev ^^
out of curiosity, what's the intent with hide?
(AXIS,stop) came up because someone wanted an infinite-loop gcode
it seems dangerous
SWPadnos: for chris's tool length probe, he has to put certain moves in the gcode program. but they're mostly useless in the preview plot once you've got the code debugged, and they confuse the limits calculation. so you can put (AXIS,hide) at the stop and (AXIS,show) at the end to pretend they don't exist.
ok - that makes sense
putting it around a rapid somewhere could be surprising though
there's no real guarantee that the preview is like what the machine will do
that's true, but probably unexpected
O100 if [previewing inside axis] do one thing O100 else do something entirely different O100 endif
I added a wish list item about pivot length and tool length. I want use the posted pivot and tool lengths in addition to the dynamic pivot and tool lengths to run programs from other machine controls.
I am not sure how you write the "previewing inside axis" conditional statement, but I'm sure it exists
what is a dynamic pivot length?
the distance from the gage point of the tool adapter to the pivot point on the rotary head
I guess I'm wondering how that would be dynamic, for a given machine
maybe the term dynamic should be defined
heh - ok with me :)
it is a static number for a given machine just as the tool length is a static number for a given tool. The control uses the static numbers to do dynamic compensation for the 5 axis tool length compensation. clear huh?
so the post will take some length (written to the file as a note) into acocunt when generating G-code?
this then needs compensated out of the gcode program to be able to use the program in EMC2
There are several ways to do it.
if anything other than W changes from the post as a result of that value then it may be a hard problem
it is just a W change
ok, then it may be an easy problem :)
cradek suggested using G54 W and this will work
is it possible for the post to write the value to a parameter instead of (or in addition to) a comment?
I could also remove the static numbers for pivot length and tool length and then run the program
I could do that in my post for files going forward but I have a 'plethora' of previous files.
I could also put the entire compensation calculation in the tool length
an awk script could probably add that to existing files
very possible - perl too
find (PIVOT LENGTH = xxx) and write that out plus another line #1999=xxx
adding that to existing files is an easy answer
seems that way. writing the awk is left as an exercise for the reader :)
I didn't want to be changing the configuration in EMC and I didn't want to lie to the tool length - both error prone operations
the other thing you'd need is a variable that has the machine's actual pivot length
that could probably be put in the ini file in RS274NGC_STARTUP_CODES
yes and be able to sum them - and the tool lengths also
oh - you need to correct the tool table also?
yes - as the previous posted programs have a pivot length and a tool length calculated into the gcode positions.
oh, so the tool comp is partly calculated by the post, given a nominal tool table and the pivot lenght
no the tool length is posted into the positions and the tool lengths MUST then match the numbers used.
ok, the post has already done tool length comp?
yes - in W - the X Y Z positions in the gcode program are compensated for the pivot length and tool length
ok. I don't know if that will work with just a G54 W offset (cradek may know, he certainly knows more about that than I do)
I am sure it will. I would need to determine the difference between the two pivot/tool length totals and put that amount in the G54 W
the actual tools will probably have different lengths also though
than the post thought
yes - that will be taken care of by the current compensation - I just need to remove the previous compensation
so you need tool length comp (per tool) in addition to the pivot length (per posted length/machine pair)
it sounds more complicated than it is
well, since tool comp can be done relative to a "standard" tool, you may be able to do it all with just the tool table
make the standard tool the pivot length difference
it could all be done with the tool table
then offset each other tool by the actual difference in tool length of that tool vs. the posted length
though that probably wouldn't work for pivots that get shorter :)
(no negative length for the standard tool)
why would negative lengths not work
I think that only works for relative lengths. I don't know if you can set the "standard" tool to a negative length
if you can, then it's a whole lot easier
I will try it to see if it handles it. I am sure it will.
then we can check off that feature request ;)
yes it can be but I will still work on getting the numbers into the gcode program. Every time we have human intervention we add another opportunity for error. If I can run with the normal pivot length and tool length and have the control handle the "extra" pivot length and tool length from the previous gcode program we eliminate a lot of human intervention.
what are the programs named?
(ie, the extension)
.nc and .pu1 and .txt
ok, if you can write a filter to add/change whatever needs to be added/changed, then you can make it un automatically when the files are loaded into AXIS
.nc is from the mastercam system - .pu1 is from ncl and .txt is usually a hand coded program. we could standardize the extension but this gives us an idea who and what did the program
in the previous programs the pivot length and tool lengths are in comments. It will be a simple matter of editing the programs to add a parameter line. most programs have less than 30 tools.
the tool table changes should be automated, since I'd expect the tool lengths to change from time to time
or do you preset them to a specific length?
for machines with 5 axis tool length compensation the only requirement is to get the tool long enough to work. for machines without 5 axis tool length compensation we set the tool to a specific length.
ok, so the table values may (will?) change whenever a tool wears out
good night - must go watch fireworks - thanks
sure, see you. enjoy the - uh - fireworks :)
yes the values change as the tool wears but if there is much wear then the tool will be changed
right, so that has to be done with the tool table, and at least every time the program is loaded
if not more often
a "filter" could write a new tool table, and using gcodemodule, it could also force a tool table reload
is scripts/latency-test usable from the command line, or is it a component of stepconf?
it's usable outside stepconf
Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2008-07-05.txt
so, i got the midibox circut board code down to 18 minutes from 183 minutes! AND figured out how to get 1 pass trace isolation out of pcb_gcode AND figure dout how to get .NC files to .DXF files so i can mastercam them ;)
no more crazy wacked out all over the place cutting.. it'll all be in a neat orderly fashion
hm I just bought a surface grinder
chr0n1c: yeah, optimizing rapids by changing program order can make a big difference in milling circuit boards
good morning all.
jepler: recall my AXIS realtime delay problem? I think it's related to my jogwheel/classicladder hal file.
Roguish: that's possible; running too much stuff in a realtime thread with too tight a deadline will cause problems.
please look at: http://pastebin.com/d1aaa6f38
there are some lines here that i lifted from awallins, but i am not sure exactly what they are or what they do. in particular the '....tmax' items.
they mean nothing and can be removed from your hal file
i've been rtfm'ing and have not found them in the docs.
that's what i thought.
08:22 < chr0n1c> so, i got the midibox circut board code down to 18 minutes from 183 minutes! AND figured out how to get 1 pass trace isolation out of
hal constantly records the time for a given realtime function to execute, and the maximum time. They are available in HAL parameters .time and .tmax.
why would you want 1 cut isolation
that sounds horrible
if someone uses "halcmd save param", these items will be written even though loading them into the system the next time doesn't do anything useful
also pcb gcode ignored Z feed parameters
unless youre using a new version and they listened to me bitching
i also think i can change the thread timing on the jog wheel. move it to a different, slower thread.
Roguish: moving stuff out of base-thread (if you have stuff in it), getting rid of anything that's not needed, and increasing the times of all threads seem like steps you might try now
i will give it a try. thanks.
anybody awake this morning
hi stuart. barely.
it's 16:35 here
maybe morning is not the correct term?
I have a question about lead screw compensation.
should I put the information in the file starting with the most negative position?
lowest to highest positions makes sense to me
one direction or the other makes sense to me
[14:37:52] <cradek> http://cvs.linuxcnc.org/cvs/emc2/configs/sim/screwcompX.dat?rev=1.1
thanks - I will read it
I had looked for something but was unable to find it
not sure about the docs
but I found a little example
this looks as I expected
the cinci repeats very very accurate
I dialed in a 16 inch diameter lathe face plate using the XY axes. Then I adjusted AB home position to swing an indicator on the face of the plate.
I can shut the machine down, restart, home the axes and the AB swing repeats within .0005 tir on the face of the plate. about a 15.5 diameter circle.
this is much better than the MDSI was able to do.
why is emc better at that? did mdsi not home to index right?
yes - I am impressed
I don't know.
maybe there's a FERROR setting that was bigger
maybe the machine is not as sloppy as you thought - that would be nice.
my guess is it didn't handle the index as accurate.
that is probably the case.
the recommended following error for all axes was .055 @ 100 ipm.
It was still able to cut parts 'relatively
we could cut +/- .01 parts with it
for most 5 axis aircraft work this is sufficient
the blend of tool motion was pretty good too
This should allow the blend and accuracy to be better overall
well - I am going out in the shop to play with the comp_file for the A axis.
can you measure the rotaries well enough to use comp?
A has a limited range of movement, right?
oh yea - I move the x and z along the tool axis and calculate the angle using ATAN. the W axis is good for that also. This will not be the final set up because I don't have X Y and Z comped with the laser yet. I will do that next week then do the A and B using the comped XYZ.
forgot - I have a tool in the spindle with 10 inches of straight shank. this gives me a lot of space to measure the angle.
very clever. I can see where doing XYZ first is needed, and then you can build on that
gets very accurate
time to play
anyone got time to answer some idiot newbie questions?
Well I'll ask them anyway
that's the spirit
that's the spirit
great minds think alike I see
we lesser minds doesn't i see :)
I wonder if mediocre minds think alike too (not that we'd know)
mung: you have used up one of your questions so far :)
Um from experience I'd say mediocre minds think alike.
I've just got the ubunto live dist, and setup the steppers, and then run the emc2 from menu, and seen there is a demo file autoloaded, and then saved that to a gcode file...... now how do I run the gcode file to get the stepper to move???
I could RTFM, but I am too lazy!
in AXIS, you can go to the help menu, and show the AXIS command reference
[15:47:59] <cradek> http://www.linuxcnc.org/docview/html//gui_axis.html#r1_2_1
Unfortunatly I got no net access in workshop, and the machine by the lathe really sux for trying to read docs (tiny screen, and too up high). I get the feeling I am going to have trouble going back and forth between my browsing PC and the workshop to get info.
print out the page and take it with you
get a long spool of cat5 cable
thanks for the link cradek, will check it out may be back later
the pdf docs are installed on your system
and contain the same information
yeah, there are so many ways to do things...... all of them tooo much trouble
in this case, you want the EMC User Manual available in the Application menu
mung: it's very bad style to ask for help while saying it's too much trouble to figure anything out on your own.
I'm just going to checkout cradeks links
I am a master of bad style
many people here are experts - save the hard questions for them
is there a quick start manual
just a little friendly advice.
that link I sent is very close to the quickest start possible.
OK thanks cradek, I must stop typing and go and read the info. thanks to all, probably be back later....
hope you get it going, good luck
the lead screw comp files are set up and working - I worked with the B axis to check the functionality - I will collect data with the laser I hope Tuesday
oh right - A is the "nod" on the head
so it is limited
yes - both A and B are limited
(I had wondered how you would apply correction to a rotary table-type device, which can run multiple revolutions)
A move +30 -20 and B moves -30 +20
for multiple revolutions you must make sure the comps equal zero for every revolution
a single move that does 10 turns would run out of comp data though, unless the repeating is accounted for in the comp code
those comps aren't cumulative, so they don't have to sum to 0 (though they should :) )
on a Fanuc control the comps are incremental and additive
why should the comps run out on 10 revs
maybe that is a case for a rotary scale - 0 to 359.999 degrees
yeah - it's the modulo axis thing - I don't know if it's implemented that way
I will keep trying until someone implements it or I learn how to :) :)
I won't put EMC2 on the viper until I have the rotary scale
I'm pretty sure it won't work for a continuous motion rotary as is
that's ok - for now
comp is being done in HAL, so the HAL component doesn't know anything about what the position command actually means
oh I thought you were talking about the rotary scale
I think that's the way it is now anyway - I haven't looked (so don't take my word for it)
Jeff had done something for modulo axes, but he took it out - I guess there were some issues with it
resets to zero every time it hits some number (like 360)
I like that
I thought that an angular axis was wrapped linear. If so shouldn't the axis comp file continue across 360.
hmmm. I may be wrong about comp (at the moment) - I don't see anything that looks like screw comp in the src/hal/components directory
I'm way out of date here. Comp used to be a file in the toplevel directory that got applied in user space.
it may still be, but I recall some conversations about moving the information into HAL
Hi Ray - is there still a 240 something limit to the comp table for each axis? If so it is not possible to comp a full revolution if you comp every degree so passing the 360 mark or going multiple revolutions is a moot point
that's not a position limit, it's a "number of data points" limit
yes I understand that but if you comp every degree you run out quick
isnt position interpolated between comp points too?
yes it is
screw comp is in control.c, which is part of the realtime motion controller
I can imagine a worm that might have some repeatable error. I can also imagine a worm wheel that might.
I can't imagine a hardware error that would require fixing for each degree.
Back then the comp was applied as a linear adjustment between pairs of points.
that is what I have used on the cinci. It may be overkill but I didn't want to go too far between points.
renesis, 1 pass, not 1 cut...
that doesnt make a ton of sense to me
because pcb will usually have islands to cut
like, youre doing one isolation pass, or what
on the cinci the motor has a small gear driving a large gear on the end of the worm shaft. The worm drive a ring gear with a smaller pinion gear on it. The pinion runs on a rack. The pinion is a split gear to allow adjustment with the rack. a lot of gears and I thought a lot of comp would be in order.
rayh; did you make it home ok with the load?
anyway, i use 60deg conicals with .005 tips, like .006" deep, .008 entered as diamater, and i do .02 isolation and .004 stepover
much less stepover, and itll sometime push copper to the side, into the path of the old cut, instead of cutting it
... i'm using 20 degree gutters, i can get a nice .003"- .005" line with them
much less than .015 isolation and its a bitch to solder. someone is going nuts right now over ghetto vias on the .008 space/trace QFP board i did for him, i cant imagine how much more difficult it would all be without the 5 passes of isolation cutting
and they are carbide and VERY sharp ;)
all the more reason to use more passes
oh i said 60 i meant 30 =\
well, i haven't vut it yet.. i may need more passes, but it looks very good on paper.. i had it running last night when i was sleeping with an ink pen
cut it yet*
but i dont know what you mean by pass, if you mean youre only doing on isolation cut, then your shit will be like one copper chip from failure, always
also remember that you cut has a triangular profile, a V cut
if i drop the bal point pen .005 it writes huge lines if i only drop it onto the paper .003 it writes awesome thin lines ;)
so at the bottom, your isolation is under .003
good advice, i'm not trying argue with you ;) just explaining myself..
like, i seen high speed PCB CNC cut boards that are like on pass isolated, its like a waste of a fucking machine
yeah i dunno, maybe you machine and board is diff
i did the one pass isolation in pcb_gcode so i could get a god dxf from the NC file and import it into mastercam and do my own toolpaths so i was like hmmm... lets try one pass
but ive thru ghetto board hell and back enough times, more isolation will make the board better
after you isolation cut, you use pliers to pull off the excess copper ;)
well then thats really alot of work
there are theese stones for cleaning pcb's
because you can do 1 pass in pcb-gcode
yes, stones... sandpaper a mill bastard fine tooth file...
you just set the initial isolation to the final isolation, or whatever those parameters are called
that should clean out the chips
im pretty sure that works, and stepover is basically ignored
yeah see when i isolation cut, there is no excess copper
if you do over 50% overlap, the copper likes to be pushed to the side, instead of being chopped up
depending on feed and cutter edge, but like with 50% or less, those dont matter very much
these cutters actually chop up the copper i was impressed
well of course, single pass
there is fine copper dust (not good i know) all over the machine now from the last board
what im talking about happens when you go in to cut passes after the first
haha my machine prob has FR4 and copper in every crack
working fine, i gotta break it down and clean/retune it, tho
been a year and a half or so since i put it together
because yeah, maybe that cool in a machinist sense, .005 gaps
but to actually work with, like assembly and reliability, that shit on an unmasked board can be hellish
i know someone that actually uses fill cutting for all his boards, ive used it on a few, theyre much easier to work with, cost is forever to machine, tho
heh, pcb-gcode docs says they dont actually think anyone uses the fill cut files
180 minutes isnt long
the time youre savging in art project bullshit and chemical safety and failure at aligning the toner transfers or whatever
180 minutes is forever
then electrically testing the boards after an etch process, because jezus fuck that fab tech needs it
yeah youre not really taking much more time
whatever, if youre doing electronic project, you prob have some other shit to do or research while its cutting
lol... 180 isn't long... i wrote a 7 hour g-code program by hand once ;) (i got paid for it)
I'd bet you chemical and uv is faster.
jezus fuck i hope you used subroutines
no youre not understanding what im saying
the process itself might be faster
but setup and testing make it take about the same time
and you actually doing shit most of the time
toner transfer dosent really work well except in special cases either
180min cnc cycle is 180min to handle more project work
or have lunch
i'll take slower over not having to breathe chemical fumes that don't grow on trees
i only have to electrically test do to ghetto vias
its not like etch shit where its a learning experience
when i do boards, theyre done, what i end up with is what i did in the pcb editor
uh.. it's not really a learning experience with uv..
etching after CNC drill instead of just machining traces was a fucked up waste of time
and considering lead time from prototype fab houses, 180min is not so long
I'd rather have the cnc do some cutting of steel..
and have lunch meanwhile
though pcb probably pays better.
yeah i dont see how thats relevant
whatever that works
yeah thats what im saying, this shit when i do it always works
there is the traces in axis
okay yeah, thats single isolation pass, with your cutters, i would not want to be the guy assembling that board\
.. it'll be me
i do not want to be you\
i hear the advice on soldering with barely any isolation... i may add another pass before i cut the actual board
not even just soldering
copper chip, fragment of pin after you clip, some random piece of domestic debris
anything can bridge .005, doing .008 shit is bad enough, im pretty much at the point wher id call that doable but impractical
* Sweeper sticks a big sheet of styro on his wall to hold salvaged chips and other assorted through-hole components
really, with the cost of pcb, and the cost of time,...
the time it takes to assemble a double sided board without thru hole plating isnt worth it
styro = static
you can get anti-static foam
not here! :P
like they ship samples in, black or pink, feer
just order shit from maxim =)
oh that's other foam..
besides, these are salvaged.
maxim = jewelry boxes and black foam, i think
if they're sensitive, they're already dead
static death doesnt happen nearly as often as people make out
ive had an nvidia card running in my box for a couple years after it had spent month kicked around a carpet
then I don't risk much by storing chips on a styro sheet :D
and i pic microcontroller chips out of my carpet and into a devboard with no issues pretty often
well, doing that is asking for it
yeah but it does happen
though with $1 components it's ok..
it'd be work with a 250$ fpga.
if I had antistatic foam, I'd use it
I asked around at shops here, nobody has it
well, use styrofoam then :)
stuff I buy new sits in its anti-static foam
I think it's worse handling the foam by hand then touching the chips..
not the chips building static where they sit..
(just what I think it might be wrong)
yea...rubbing the foam and then grabbing the chip = not so good
it's a very nice visual inventory tho
if the silkscreening on all the chips was white, I could read the numbers from where I sit
i gotta do take some mustang dash inserts to get silkscreened monday

DYSLEXICS OF THE WORLD, UNTIE!
anyone know how to repair parallel ports???
get a PCI parallel port card
or ISA, depending on the age of the PC
recommendations, with opto isolation?
I don't know of any parallel ports with isolation, the parport was never meant to interface to anything "unknown"
there are breakout boards that will provide isolation though
what is the recomended way to interface more than 4 axes, as parallel only has 8 outs?
[23:09:09] <SWPadnos> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?EMC2_Supported_Hardware
personally, I like the Mesa FPGA cards, because they're quite capable and they're completely reprogrammable
there are other options that may be easier to set up for a mill or lathe
I am afraid I'm doing a hobby diy conversionon a really low budget, so want something less than £20
isolation will be difficult at that price point
I have been trying to save cash so did not bother with opto isolation and realised the error when i dropped a screw driver and shorted something
unless you'd like to build something yourself
I still have 4 outputs but 4 blew
a PCI parallel card is probably the cheapest solution - dual cards are within your budget, and if you're careful you won't have to replace it
even if you do, it's still cheap
I may just go with a standard card and be more carful next time ;)
you can use up to 8 parports with EMC (more if you want to recompile)
its screwed my weekend as I was hoping to get three axes installed and tested :(
well, if you have hardware e-stop, you may still be able to do some testing
the parallel port can have 12 outputs and 5 inputs, I think
the control and status ports are also usable, so you could get 8 outputs (barely), and still have a couple of
I looked at the epp specs and it shows only 8 data lines
8 fata, 5 status, 4 control
hows does the hardware e-stop work?
is, you wire relays and whatnot to shut down the machine. you can optionally rell EMC that the machine is off, and optionally allow EMC to shut the machine off
pinouts here: http://www.linuxcnc.org/docview/html//hal_drivers.html#sec:Parport
(for the parallel port under EMC2)
just use emc hardware wizard to setup output to control pins?
if you're talking about stepconf
I really am newbie only messed around with the emc live distro for a couple of hours so far.
have you installed it to a hard disk?
no running live cd
ok, in that case any changes you make will be lost the next time you reboot, unless you're specifically saving them to a flash drive or something
its just a hacked together box of bits at the moment, as i am learning and botching together a system.
I realise all data is lost but i don't have a spare harddisk at present.
no problem - just thought you'd want to know :)
