does emc support some sort of device that acts like a camera on stadion, which is suspended by 4 wires from 4 corners of stadion + 2 degrees of fredom on camera?
I've seen similar things done with a ghost on the wiki I think
care to show url?
well I suppose it could be done
just look on the wiki page for examples I think is where I saw it
wiring up a parallel port cable here, anyone have a quick link to the pinout?
pinout for what pins are innies and what pins are outies?
what pins I connect to my stepper controller from the parallel port
what pins did you configure to connect to your stepper controller?
I haven't configured any pins yet
[00:42:21] <jthornton> http://www.linuxcnc.org/docview/html//hal_drivers.html#r1
^^ that shows what pins are inputs and outputs
genehacker: are you using the stepconf wizard to build your configuration files?
I think I need to go through the getting started section first
genehacker: very good idea
jthornton, yeah, found it, its sweet :)
I thought I remembered that LOL
I just got my chinese Toshiba driver in. I have been luking this project for years and finaly taking the dive!
I have a question, can I make a hybrid like steppers and servos ?
it ain't easy afaik
Beezer: do you mean steppers with encoder feedback?
only want the y axis to use the servo
so you just want to mix steppers and servos?
I don't think that is too hard to do...
great, i dont have any commitments yet
was hoping to use what i had on hand
I must ask though, is it possible to get decent stepper speed with 1/256 microstepping using EMC2?
its been very hard to resist buying an old lathe with the money I been spending on this dream.
genehacker: yes with hardware like Mesa to get really fast stepping with the parallel port you are limited by the latency of your computer
I just saw a conversion of a radial arm saw.now thats creative!
I built a computer just for emc and its been in the garage for over a year just awaiting the gantry
I see a few others bought this board based on toshiba chip
Hope it doesnt blow like some of the others
motors are 2.1A 175oz
have not yet bought a psu, I was hoping for some help choosing one
genehacker: why would you use 256 micro steps and want to go fast too?
Beezer: is that some cheap driver board from fleabay or something like that?
[01:07:33] <jthornton> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Stepper_Formulas
don't expect much from it then and you won't be disappointed... do you have a link to the manual for it?
because my stepper driver has the capability
I have followed others luck and yes I dont expect alot
I have heard that more microstepping results in smoother motion?
genehacker: for slow speeds only
ah I see
for fast speed you want 1 step
my Gecko 203v morphs from 10 micro steps to 1 through the speed range for smoothest operation
Step 1) Be already nakkid, Step 2) DUH
starts at 10 and as the speed increases it morphs to 1
Jymmm: your on the wrong channel LOL
jthornton: just responding to what you said
I wish I had the skill to build an arm like the plants use to weld.
I can't do that with my stepper controller unfortunately
if you can pick the microsteps then you will have to select one that gives you the smoothest operation over your speed range
what kind of driver is he using?
a national instruments nudrive
after buying the chinese board the motors arived with their own discrete stk based drivers
so i got those for nothing!
I'm using it because it was free
free is good
best price up front anyway
I wonder if anyone has used chaindrive instead of screws belts ect..
I've seen that on plasma cutters before
may be cheaper

Hi from Rainy Germany
is there a develop into G12/G13
or into a pocketing G code
what is g12/g13 ?
Pocketing a Circular
[08:23:25] <IchGuckLive> http://wiki.linuxcnc.org/emcinfo.pl?G12-13
i wrote this script for pocketing ->http://www.pictureupload.de/originals/pictures/020810201332_pocket_v1_c.png
it woudt be nice to use the G12/13 for parallel pocket G-code
does fanuc has g12/g13 ?
and also G77 the iso cycle
on Haas its G150 for rectangular
you said rainy germany? whom where you from?
i lookt into Fanuc11M theri no into 15 it is

building from scratch?
designing so far
do you like working in alibre ?
yeah, I got really used to it
my ingeeners often complaining on it
I don't see it any different than SW for example
do they use v12?
hmm.. I can't say I had issues with bugs
but I do mostly simple modelling
we build whole machines models
I plan to learn allibre soon
or SW, depends which will be easy to get
well, you can get alibre for free/almost free
it's surely good enough for learning
also v13 is soon around the corner
so they will drop v12 at half the price (if they do the same as every year)
so you can buy v12 at half the price + maintenance then you can upgrade free to v13
but I need windows for that
unlikely to work nicely on wine
hey I can use virtualbox :P

yea, I was looking at it and just wondering...
I personally think "frameworks" is a highly overused term and so far abstract from the actual language that "why bother at all", but that's primarily in scripted langs like php, ror, etc.
I'm struggling with what gui to use with c++ atm

Have you looked at Eclipse IDE? You can use it for *ANY* language on pretty much any platform.

SWPadnos: You know anyting about airflow? CFM tubing size and the like?
like dust control
except that bigger tubes allow more air flow
scroll to the bottom and read the last entry http://www.digitsmith.com/archives/what-is-best-for-the-exhaust.html
err, 2nd to the last "Nobody has ....."
ok, that sounds plausible
What I'm thinking is 4" duct 6ft long from the laser to a 6" adapter, to a fan to 6" @ 25ft duct
The 4" duct will basically be disposable (dryer hose)
and will fill up with gunk over time
read the last comment ;)
no dryer hose
oh, no, I mean aluminum dry duct
they dont even sell plastic dryer hose at Hd anymore
or I couldn't find it
it's all squished up, so it's hard to see
[12:32:38] <Jymmm> http://www.homedepot.com/h_d1/N-5yc1vZ1xgl/R-100050673/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053
That's aluminized paperish stuff
They also have the 100% flex aluminum duct too
Hmmm, I didn't expect to find HD with 6" flex duct http://www.homedepot.com/h_d1/N-5yc1vZ1xgl/R-100140592/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053
Maybe I'll use the adapter directly on the laser instead
SWPadnos: Use this fan instead of a dust collector; 450 CFM @ 1A http://www.ehydroponics.com/?action=product&id=203&cid=121
SWPadnos: Suppose to be 50dBa too
you should probably use a fan that doesn't have the motor in line with the air (and dust) flow
I don't know if the dust from laser cutting is flammable (in theory it's already burned), but you should think about that
SWPadnos: It's primarily fume control, not dust.
like explosion proof motors and stuff
damm, lost my internet again... back to dialup
SWPadnos: What I could do is setup a 5gal bucket in-line as a particulat collector. Maybe even toss in some activated charcoal pellets if I can find them cheap enough.
jthornton: you poor bastard.
SWPadnos: These things are HUGE http://www.ehydroponics.com/?action=product&id=2376&cid=234
like 40-60 lbs, and 5ft tall
SWPadnos: WTH?! Read the Specs tab... http://www.homedepot.com/h_d1/N-5yc1vZ1xgl/R-100396935/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053
# Maximum air flow (CFM) : 100
Does that sound right?
I bet you need a pretty powerful blower to get anywhere near that
I'm looking at 450CFM fan, but if a 6" duct can only do 100CFM, and an 8" cna do 200CFM, I'm screwed
a smooth duct would allow more airflow, I think
Yeah, that's correct.
that has a very coarse helix
and it looks like the actual duct is very flimsy, which should also waste some energy for you
note also that that is a 25' duct - if you need less length, then you may get more flow
oh you mean CFM energy?
yeah, the "wind" has a certain amount of energy in it, if you waste it on other things, then less air gets out
I think I actually need around 30ft, but might be able to get away with 25ft
Ok, if 6"==100CFM, 8"==200CFM, 10" should be around 400CFM or am I way off?
4th power, that post said
if you need 2x the flow, you need 1.189 (IIRC) x the diameter
SWPadnos: ENGWISH man , ENGWISH =)
2x the diameter = 16x the flow
Right, but I'm going my the mfg rating for airflow.
which said that 6"@25 == 100CFM, and 8"@25ft == 200CFM.
So, if I jump up to 10"@25ft, would be ________ CFM?
whatever the manufacturer says
They don't sell 10" flex at HD
just out of interest.. what does CFM stand for?
cubic feet per minute
cpresser: CFM == Cubic Feet per Minute
cpresser: How much air can you displace in a minute.
well, you need both CFM and pressure to tell how much air it really is
ah ty. I was missing the vocabulary :)
cpresser: If a room 10x10x10ft == 1000 cubic feet was filled with smoke, and you had a 500 CFM fan, it would take 2 minutes to empty the smoke (under PERFECT conditions)
its the imperial-system I am not familiar with
but the physics dont bother if you are using CubicFeet or Liters :)
SWPadnos: Ah crap... They are all lying to me http://hvac-talk.com/vbb/attachment.php?attachmentid=488&d=1169841049
but on the actual subject, I would go for the maximum diameter that still makes sense. since you can have a slower airflow it reduces the noice
hi is there a math function in emc to camlculate the int of a float? EX if i got 20.35 it shoudt be 20
also 20.9 shoudt give 20

SWPadnos: What is meant by "At static pressure"? I have not really understood that too much.
SWPadnos: Heh, you mentioned it a little ways back =)
I mentioned air pressure, I don't know the specific meaning of "static pressure"
[13:25:32] <SWPadnos> http://www.physicsforums.com/showthread.php?t=177988
[13:25:57] <Jymmm> http://www.wisegeek.com/what-is-static-pressure.htm
ah, ok. it means "once the system has reached equilibrium at that airflow"
add CFM to your search terms
Hmmm, static sounds like a fan blowing into a home with no exit
Jymmm: think, balloon. that is static pressure.
I take it to mean that the pressure is no longer changing
when you first turn on a fan, the pressure in the hose is the same as the room
at that instant in time.
with the fan running, the pressure in the hose increases (this is what causes the air to flow), until it reaches some new, non-changing, pressure
that is the static pressure for the system, at that fan speed/air flow
flow roughly means P1>P2, in order to cause a transfer of fluid you need a force greater on one side then the other
so, if P1=P2 nothing moves.
can someone check this Rectangle pocket milling Produser Please
[13:52:31] <IchGuckLive> http://pastebin.com/T7tyKKcu
oh falt in the system of thinkiing if the larger value of the pocket expands it expands the Stepover SHIT
if i change the calculation of the #20 #2><#3 in #20=FIX[[[#2-#1]/#8/2.0]] then the stepover is not overtaking
ok this will work
does it actually work as you have it, or do you need more square brackets in there?
[14:05:18] <IchGuckLive> http://paste.pocoo.org/show/247645/
there is the change http://paste.pocoo.org/show/247645/
now nothing runs over the given stepover
for big mashines i shoudt be thinking of taking the first Rectangle to the full width-times of stepover and then stepover is always the given
for ouer Chees routers this is well the best it is always less or Equal to the stepover
length will increase resistance as well
a lot of people like milling zero Path
we coudt make the code working also with the Final Rect to G41/42
and Use D ftom tool table but thats on there own
this will do nothing if someone takes it as it is
oh i see the first rect that is obove zero wars only to see at the developing it coudt also be removed
line 30-39 can be removed
this displays the outline
Is there a way to see in the hal layer what tool is currently used,.i.e. what is given using t0, t1 in the ngc file ?

i will also rite a Equal to G12/G13
maximilian_h, there are pins on the motion controller with names that include the word "tool"
halcmd show pin | grep tool will show them to you
maximilian_h: this is done though hal and cl - finding the tool. http://www.youtube.com/watch?v=4nuRea6615s
they are not exported from motion ? Are they, because I looked there in the doc and did not see any
By for now
And I am not currently infront of the machine itself, but at home
iocontrol, not motion
@skunkwork: Nice video, big machine ! I haven't used classicladder yet
there is also the tool prep number also
it is getting there
Is there a way to set the feed rate in the hal layer and ignore whatever is given as the F word ?
there is adaptive feed...
I have seen the motion.adaptive_feed pins
but they are in percent of the commanded F word
Or should I add my own hack to control.c ?
since setting the feedrate with the F word is a fundamental principle of g-code, there is no way to defeat it
control.c is not the right place to make such a change anyway
the F word is handled in the interpreter, part of user space, not the realtime motion controller
made any progress on your circuit board mill/whatever your going to use it for?
none at all
came home from workshop, went right back into doing real-life stuff
we are still plugging away http://www.electronicsam.com/images/KandT/conversion/servo/belts.jpeg
@jkmkasunich: What would be the right place ? Adaptive feed is manipulation the feed rate in control.c, so why not set the absolute feed rate there too
because the absolute feed rate doesn't come from there
if you don't want to let the programmer set feed rate in g-code, how _do_ you want to set it?
By using a panel with python
and the python hal module
I can't imagine why you would want to do that
I'm sure you have a reason, maybe this isn't a machine tool, it is some custom application?
anyway, I need to leave, sorry
Yes, you are right
does it move?
not quite yet. the pullys need to be tightened in the right place.

and then a new Side with the file and the Code and the text
edit the page and follow the leader by example and insert your new page... save this then a ? shows up and you click on it to create a new page

if you want to make a full wiki page for the pocketing routine, you should add a link to the "G-Code Generators" page as jthornton said
you then click the ? and edit that page
yea, if it is another pocket routine put it on that page
If you want the program file to be available for download, you need to upload it first. I don't recall exactly how to do that, but the instructions should be available from BasicSteps or a link from there
err, add a link *on* the G-code generators page

Hi there in the world
i fionisht now also Circular Pocketing with spiral mod -> http://paste.pocoo.org/show/247773/
but it seams that i have a problem to come back from Spiral to Circular center at some numbers at most it works
but sometimes the error generator messers a diverence in the center
arcs are always fun to figure out
i read that the difference must be lower then 0.002inch
something like that yes
coudt someone please test a littel the code ?
igo to bed im done with the calculatins for today
it loads for me
change the diameter by 1
yes, I get the arc error
yes it does
this is the value if i come out of the Spiral to the Finish Circel
if i calculate the point where we are and subtract the value to go take it hafe it is not exact enove
yes it seems to only affect odd numbers
the calculation intern is float i guess with 12 numbers
your radius is off by 0.5 which sounds like a math error not lack of precision
or a logic error leaving the tool in the wrong place for an odd number
so whi it works on strait numbers ?
G3 X[#4-[#2/2.0]+[#1/2]] Y#5 I-[[[#4+[[#20/2.0]*#8]]-[#4-[#2/2.0]+[#1/2]]]/2.0]
use named vars for crying out loud ;)
listen to Alex he taught me every thing I know without telling me anything strait up :)
#20 is the miss cause it is Fixt
no same error

i find out the Clou tomorrow BY
Yeah, I think I like "needs more salt" too
this shoudt be solvable or dident you think?
or hotsauce, whatever kills the taste
are there a parameter to find out where the programm is Right now cause it tells me the error with the numbers
IchGuckLive: yes it is solvable take a look at my simple g code generators on the wiki they do the same type of move for the counterbore one
robh__: do you know which sinumerik 810 files are machine specific out of PCP, TEA1, TEA2, SEA?
i'm pretty sure that TEA1 and TEA2 are machine specific but i'm not sure about SEA and especially PCP
SEA think if rember right this sets axis working limits
they are mostly 9999999 and -999999 so ie no limit of where you can work in the travel
PCA is all PLC info and stuff, PCP not sure on this one, might be a mill thing? have you found the files for a 810 have you
PCP is the PLC proggram file
PCA is the PLC alarm file
yeah i found a complete set for a 3 axis vertical
the TEA1&2 parameters seems to be very well documented by siemens
but there are A LOT of them..
yea just DNC them into the machine and see if it fix's it
any point in trying to read whatever data is still in the machine for backup?
info to load it into the machine should be in the manuak unless you like typing alot of numbers
you can try
yeah i have a pdf file explaining the process on the operator panel, as well as the siemens pcin software
it might have gone back to default values most time a reload on the tea stuff brings it back up once it knows what it has to become
this stuff is pretty interesting, i like working with unusual hardware :)
well hope you can get it fixed and up and running
DaViruz, heres a machine i retrofitted from an old Mitsubishi control http://www.youtube.com/watch?v=UlW1s2BNixo

it holds two tools
