does clicking show hidden files cause the program to crash?
this is the second time I hit show hidden files in the file open box and I could no longer access anything in the computer

Guest203 there was a bug with an older version of axis that did that as I recall

any help getting linux to see the network card?
Guest203: what computer hardware do you have? 98% of the time (as long as it isn't wireless) linux finds the network card.
80% of all statistics are made up on the spot.
it is a IBM S50 8183
it did not find the card
I am blind to the net and the card it would seem
I am a linux newBe but do know some things as I setup servers with redhat
have done comand line work
but very rusty and it was meny years ago
heh - I was a linux newbie also. but it really doesn't take long to figure out.
any help in getting the computer on the net would be a life saver
what ubuntu version are you using? dapper drake or hardy heron?
I am suprised it didn't see ibm hardware.
have work to do, do not want to fight Mach any more
it was a live cd install
I would think that would work. You wouldn't happen to have an extra network card you could through into it?
(it isn't showing up in the network menu?)
only thing on the network menu is the dial up
point to point conection
it looks to be the modem conection
Guest203: there may be a hint with command: lspci|grep -i ethernet
no modem is installed or part of the MB so it must be thinking serial modem or conection
comand not found
you might want to do some searching on http://ubuntuforums.org/
or even ask a question
wait - wasn't there some protected drivers you could install? (or whatever you call it)
why would the lspci command not work?
sudo lspci whatever
are you talking about getting the onboard ethernet to work on this? http://www.superwarehouse.com/IBM_ThinkCentre_S50_8183/8183GNU/p/457741
this page: http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-50535
says it's an intel pro/100 chipset. you positively do not need special drivers for that. it must be disabled in your bios or something like that
it was shut off
hope it works now
the tip jar is by the cable modem
simple things can bite you hard
thanks a mill
it is working now
skunkworks pinged out in shame for not figuring that out :-)
he is a great guy and of great help
he helped me get other problems fixed
we can not all bat 1000
I am a tech and I should have knowen better
all this is so new and so much reading I got focused on linux and not the hardware
in doing a update it wants to update the rtapi.conf file
what do you mean? updates update packages, not files
should I let it and then re edit it to work again?
it is asking me if I want to keep the file or replace it
oh, just keep it
needed to kill the interupt that was killing my EMC
would that also effect windows?
mach would freeze the computer at random times
I can't say what mach and/or windows do, I have no clue about either
also had creep on zero so threading was a pain as I had to keep tweeking the zero setting
many things can cause that with steppers, especially step timing parameters. be sure you get them right when you use the stepper configurator in emc.
how were you running servos with mach?
step and dir
ok, that has all the same problems as steppers
well, plus more
mach had no idea they were servos
you may have encoder noise problems going back to the geckos and you'd never know (except for gradually losing position)
I have my Gcode on a USB chip
how do you get EMC to read the chip?
there is no drive select in file open that I can see
plug it in and an icon will appear on the desktop
linux will see it
but I can not get to it from EMC
welcome back skunkworks
drag it to places / home / emc2 / nc_files folder
it will be in /media/<whatever the name of the USB disk is>
it wasn't in shame.. it was in hibernate.
got it now
it's a better idea to copy the file to the hard disk as cradek says though, since the USB subsystem sometimes causes latency problems
(usually at plug/unplug, but it's better to be sure)
I do a ton of hand coding and like to be in a warm office then a cool shop
so I like to take the code with me
get putty (if you use a Windows machine nornally), and log in to the CNC remotely :)
smi fixed the latency issues?
one could unplug the chip after it is loaded into EMC
yeah I do that too, but I use networking...
worked like a charm
Guest203, yes, copy the file, then right-click and unmount before unplugging
I have been pluging and unpluging like mad
would that brake something?
unlikely if you're only copying *from* the USB stick
but it's similar to Windows - you're always supposed to "stop" the drive before unplugging it
copied to it as well to move the error mesages to this computer
it kind of depends on how long you wait after accessing it
safer to unmount first
so what is the best GUI to use with EMC?
is there a good one to use/ the defult one is OK but would like a better one
best is relative
there are lots of options. you should try them all. your question is impossible to answer.
thought there may be a download of a good GUI
all the supported GUIs are included, I think
and some that aren't :)
so what one do you guys use?
which one do you use and not like?
it is for a lathe
and are they hard to customize?
night - good luck. (I love axis)
AXIS knows the most about lathes
as far as I know, the only one that has a lathe mode is AXIS
unless touchy also knows about lathes
yes, touchy does as well
ok, then I'm back to "best is relative"
is axis hard to mod?
Guest203: AXIS is nearly impossible to customize. but it starts out fine, so you don't have to waste your time.
is there something particular you're looking for?
it may actually be impossible :)
(could save you some time looking)
it doesn't start out all OH GOD MY EYES I MUST CHANGE IT! so you can get right on to using it
was wanting spindle seep reading and a few other things like mach
actually, the best way to use AXIS is with the keyboard shortcuts. there's a summary of them on the help menu. it's so much worth everyone's time to learn them. using a mouse to run a cnc sucks.
sim/lathe actually has that as an example
some things are easy enough to add with some HAL components and pyvcp display elements
the GUI in mach is easy to mod and has tons of info
you'll want to read about those subjects a bit
the GUI in EMC2 isn't as easy to modify, so you won't be able to put flashy thingies on the screen without doing some work
(it's easier, in that you have the source code, but harder because there isn't a screen builder application)
in all seriousness, you'll get the best help here by asking "how do I accomplish ____ task" instead of "how do I make it like mach" because we're more knowledgeable about the first kind of question.
on that note, I think I'll go to bed
well, not that the note really matters. night guys
so what is used for rem/ comments?
comments in gcode can be like (comment) or ;comment
EMC is saying I have a error in the Gcode
that is a comment
and what's on line 3?
unless it will not count the comment lines
Is anybody on who could advise me about following error? I'm setting up my first EMC machine. Have the servo's jogging around and am ready to fine tune it.
My question is: How much following error is acceptable?
(program start - turning cycles)
Is this amount representetive of the part dimension errors I can expect?
Guest203: pastebin the first several lines of your program
Wesbaker: You should try to get the following error as close to 0 as possible, it will depend on your machine... If you have a large follow error it will show up in your parts..
WesBaker: kind of. you should get it as close as possible. on a good setup you can often get tuned so you stay within a handful of encoder counts when cutting, and maybe a couple dozen when rapiding
a sloppy machine, poorly tuned amps, bad lube, etc will of course make it harder to get excellent results
I have a 5 x 10 CNC router. Huge machine compared to what I've been using. The X and Z axis have about 2000 counts per inch resolution on the encoders.
[03:22:45] <Guest203> http://pastebin.com/BfbtgwMA
The Y axis has only 700 counts per inch.
ouch, that's pretty low
WesBaker: the error is line 2
I am using halscope to measure the following error.
I am getting about .0015 peaks during accel. It was a lot more until a guy told me about the ff0, ff1, ff2
I don't know what they represent, but see how they have reduced the error.
WesBaker: if that's on your 700/inch axis, you won't get better
... that's 1 encoder count
The 700/inch is about tripple that right now. The .0015 is on my x axis with 2000 count per inch
So is an error of one or two encoder counts where I should set my mental goal of "good enough" for the hardware the way it is configured?
that's 3 encoder counts...
yes that's really quite good.
if you can get 3 counts you are doing very very good
if it sounds right and it's tracking that well, you are done, and you did a good job
general rule of thumb is that encoder resolution should be 1/10 of the accuracy you are aiming for
OK, then that might lead to my next question. If I can get .0015 on X during rapid moves and .004 or .005 on Y then what should I be able to expect as far as interpolating a 4" circle?
measure it and see
Would it be 4.000 +/- .005 in one direction and .001 in the other?
I'd measure it but right now when I turn the spindle on, I get false inputs on some of my GPIO and trip limit switch over travel errors, etc.
that depends more on the tightness of your machine. I suspect you'll see excellent path following in halscope.
Path following in halscope? What does that mean?
if you run a circle program and watch halscope, you'll see very small ferror because your acceleration while cutting a circle is very low compared to your tuning rapids
found the problem in the Gcode
what is halscope?
Halscope is a dream tool. If you haven't played with it, you are missing one of the most cool tools in EMC
halscope lets you simulate a DSO for your internal variables, pins, signals, i/o.
so how and where do I get it use it?
ok found it
I get it from the EMC menu. Can't rmember where but the menus are basic so you will find it quickly if you look
If you know how to use a basic o-scope, it's child's play from there.
If you are unfamiliar with oscilliscopes then it may look foreign.
If you play with it though, it will give you a sort of strip-chart record of the change of state and values of various i/o points and internal values
I have used a scope since I was 15
that would be over 30 years
cradek: So I I want tighter following error than .004, I need to get a differnt encoder or a different pitch screw.
Guest203: Then you will be in business quickly with halscope
guest203: It's so usefull it doesn't even seem fair. No probes. No leads.
is setting up backlash hard or any tricks to it?
I have read in the manual about it
not a question for me. I'm new to configuring emc. First machine. Just trying to figure stuff out.
juas wondering if I have to watch out for anything
lol me too
guest203: If you actually read some of the docs then you're miles ahead of me. Maybe cradek is still on.
WesBaker: .004 is 3 encoder counts on your Y - you really need more encoder if you want to improve that.
was using mach till now
I'm a mach3 user as well. Love it. But my old machine was simi-open loop. Pulse counts out the parallel port to Gecko drives pushing small servo's with encoders.
it is good for mill and router, but sucks for lathe
Too late for me guys. Thanks for cradek's input. See you guys later.
so is backlash comp tricky to setup?
you still there cradek?
the backlash compensation parameter in hal?
not sure, have to reread the docs
just want to get this lathe up and running so I can get the work done
it is down for the moment, have to setup backlash first
I'm no expert on it but I would setup a dial indicator on your axis jog in one direction to a even number, then jog backwards just till the needle moves.. the difference in position would be the value you enter..
true, I know that, just not sure how to tell EMC what the backlash is
It's in the ini file, under each axis settings, e.g. [axis_0].. use BACKLASH = <value>
also something about setting other things if you use the back lash
PCW_ is now known as PCW
these look nice: http://www.trossenrobotics.com/c/robotis-dynamixel-robot-servos.aspx
although theyre made for higher voltages than usually used in RC
they are higher spec than my steppers :)
3 of those on my mill would give me 10x the torque and 2x the positional accuracy
guess they need some serious cooling if you want to run them continously
they are geared like crazy, so the high torque comes out only at low rpm
how about speed?
probably way slower
0,2s / 60deg
which is umm...
but I'm not sure they can rotate 360deg continously
rc servos at least can't, they position themselves based on a potentiometer
and only 256 positions I think
well it depends on the accuracy of the electronics
these might have encoder or hall-sensor as feedback
the signal is analog
those robotic ones were rs485 or something, not the RC pulse-width (?)
ah, could be
or, it could be that you can chain 254 of these into one daisy-chain of servos
so the feedback encoder count might be higher?
hm the best one has 0.07deg "resolution"
that would be 5k count/rev
you remove the 'encode' when you convert them to continuous, usually
or with the 1/164 gearbox it is 32counts/rev on the motor
you replace it with an external speed pot
or 2x fixed resistors, and the control signal becomes reversable speed control
eek $20 just for a thrust washer :)

fingers in lathe. naughty
lathe into lathe :) even naughtier
we'll have uncrashable machines soon
in our lifetimes, anyway
if there was some way to map the tools and the chuck to a no-go zone like the machine limits that could not happen
yeah it needs total self awareness
sensors in absolutely everything, including the tool tip
like our fingertips and tounge are the most sensitive parts of our body
so hold your fingertip close to the chuck at all times. problem solved.

I used to tell maintenance guys that worked for me to always place their hand between the object they wish to hit and the hammer so they have a good idea of the strength of the blow

what data format does OCL expect? does it define the mesh?
e.g. to use it from blender, would I build an ocl style mesh and pass a pointer?
you could push the triangles to ocl in a loop
if you know how to loop over all triangles in a blender mesh
and access the vertex coordinates
that's the only way to access them in a script, with the old API
you can get at the blocks of memory in 2.5
python is not the most efficient way to do some of this stuff :)
anyone have any NewEgg promo codes?

MattyMatt: I didn't talk with yoyek long time
try private, he's not biting afaik
nice script, terrible english in the GUI
I'll try to contact him
ah cheers :)
i didn't pay attention to nick
I'm permanently on #cam too. that might be a better place for yoyoek to meet me, for my interrogation
he did put in a comment that he wanted help with English spelling, well here I am
it would be only polite to send him this script all done with Polish GUI and comments :)

best thing about the mechmate, if it fails you know instantly what it is if you built it!
you know if something is wrong if your 12mm circles become like 20mm ovals :P
yea, that's bad
easy to find the error though =) I need glue for the set screws :P
havent gotten around to fix it, despite knowin they get loose sometimes =)

Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2010-05-13.txt
I wonder which logger actually owns that file
dang not much more mdf left to play with!
can you you make emc do inner corner in a certain way somehow?
what do you mean?
lets say I mil a slot and want "sharp" corners
and then emc knows its a 6mm tool and make so that a sharp insert would fit
so it cuts a bit in the corner
you would have to program that path
as I said, its a bitch cadding for that
especially if you have a load of slots and such
frallzor: v carve can make these T slots I believe
or whatever they call them....
it's the task of a cad program
wait, v carve calls it bone fillets
v carve looks nice, but I can't afford it.
can you show a picture of the kind of path you want?
would look like a capitol i "I" I assume for a slot
[14:42:57] <frallzor> http://pici.se/p/otKjtohWh/
this is how I currently solved it, a way to big hole, I would like the tool just to go straight in to fit a sharp edge in there
frallzor: your sketch is under defined
anyhow, making solid works make the clearance automatically shouldn't be that hard?
i dont use it to make code
I make what I want, export to dxf and import in artcam =)
if its not 3D
in other words, the code is based on what you draw
you can cut into the corner using a straight line. it will not go all the way to the corner's coordinate. how far you need to go depends on the angle of the corner.
yes but I want to be able to draw the corners as should be
yeah, cutter compensation won't do that for you, it leaves the fillet on inside corners
well, that's unrealistic if you ask me, since the corners won't turn out like you drew them
no - those corners will get cut, at least
and you're cutting away way too much if I understand your picture
that was ment for frallzor, btw
well more than I want
but If I use smaller tools it will be ok
[14:48:46] <JT-Work> http://imagebin.ca/view/o8VMgck.html
the issue with that is I can select to cut inside or outside a line in artcam
havent found straigh on line
then you have to draw it for inside the line
yes what JT-Work drew is exactly right
the length of that little line depends on the angle of the corner
so your part looks like this http://imagebin.ca/view/YbNBMtdQ.html
then export the dxf from that
for a square corner, the line is cutter radius * (sqrt(2) - 1)
* frallzor loves making milling videos

I need to get a pencil for my Hardinge
so I can poke myself when I forget an offset
a few questions, bare with me now ;) new to the world of Servos and Lathes.
can I take a 'regular' DC brushless motor, put an optical encoder on the back of it and use it for the spindle on my lathe with a PWM to controll RPM via EMC? would it be able to do threading? what about positioning, if I have a live tool to do an offset hole or mill a slot, would that encoder be enough to tell EMC where it is in relation to the g-code of where I want to put the slot? would it need a 'brake' to prev
I have heard of people using Scooter motors.
frallzor: may be it's easy to write a bit of python and make a small tool in qcad?
brushless motor needs a brushless servo driver, at least
a brushed motor with encoder is fairly easy i guess
umm, no, on a lathe... that's not that hard? well dunno 8) forget what I said
I just inform you that wiki website seems to be broken

yes it does!
I have a question about hal
user space python module
I make a short script which manage a tool caroussel
driven by a step motor
on computer side there are stepgen hal module
and my python hal module
I want to change maximum velocity of my motor to find the caroussel home switch
I don't know how do that in python
(change stepgen maximum velocity parameter for example)
someone has an idea?
since that's a parameter, you can't change it except with 'halcmd'. Something like: os.system("halcmd setp stepgen.4.maxvel %s" % desired_max_velocity)
when the system() command returns, the parameter will have its new value set
yes, unfortunately this means you have to code the number of the stepgen in your program
ok thank you, I was thinking that halcmd underneath library was usuable
I know the number of the caroussel number stepgen
How motion module or axis can reduce the velocity of motion?
because stepgen provide just position_cmd in position mode
the realtime motion planner varies the stepgen position-cmd at the desired velocity, so that the limits of the stepgen never come into effect
ok thank you again Jepler
Last remark : I don't find the tooledit GUI program in EMC2.4 where it is?
in the package it's installed at /usr/bin/tooledit
there's a bug in 2.4.0's tkemc that prevents the menu item from launching it; that'll be corrected in 2.4.1 when it comes out
oups I doesn't try it
thanks for the infos
Ok tooledit works on my computer
besided being blind as a bit while cadding 2 parts for the "box" it turned out real nice
does the tool edit work right?

Guest203: lathe or mill?
lathe for me now
is there a decent toolpath viewer for window?
yea, the front angle and back angle get hosed
you can put TOOL_EDITOR = gedit in the [DISPLAY] section if I remember correctly
till 2.4.1 is released
AFAIK, what does that mean?
As Far As I Know
ie. from my memory :)
so I am working on doing the tool table for lathe
you have a turret?
there is no sample of the lathe to use as a template
no, not yet
in the manual yes
[16:22:54] <JT-Work> http://www.linuxcnc.org/docview/html//lathe_lathe-user.html
sure the manual has nice lines and all, but you can not get that into a text file
what do you mean?
I just used the headers and used tab between the col on each row
but had the brak the headers into to lines to get the col to line up right
oh, they don't need to line up
have no idea if it will work
the link you posted can up error for me
try and refresh your browser
it's more likely a server issue, the host was changed earlier today
so could one put more then one tab between numbers?
if so how would EMC know it was not a blank field
give it a try
how do i use this new tool format? .. mine is still a text file
I imagine EMC just looks for the next character
it is always a text file but the editor just loads the text file up
but that link you gave shows something i don't see on my comp
what is that?
1.2 Tool Table doesn't look like mine :)
the new file is still text, it just uses text that could be pasted into a line of G-code (with some new functionality in 2.4)
ok...i don't have 2.4 yet
there you go the docs online are for 2.4 now
k... i can't upgrade yet...mill been running since mon
so does this look like a good usable text file for a tool table?
[16:38:34] <Guest203> http://pastebin.com/GYMcz3Y5
lathe tool table
looks fine to me... can you preset your tools?
izua_ is now known as izua
what do you mean?
do you have some sort of tool holder that you can take a tool off and put it back on without losing your offsets?
tons of them
buy them by the dozen
send me a few of the spare ones then lol
I hate having to reset things
so every tool I have is locked into a holder, with spare holder for the next tool I have to make or buy
the tool table will be a big pain to do as I have a ton of editing to do
the numbering gos over 90, but not all spots are filled, yet
every drill will soon have there holder
is there a easy way to zero the tool in EMC?
I see touch off, but can that update the tool table?
I was asking about the tool zero being added or updating the tool table in some easy step or 2
yes it can... the way I do it is to zero the tool Z off of the spindle face
and tool X off of the centerline of the spindle then to a g54 from any tool off of the material Z BUT you have to have the tool offset in effect first
I move the z zero to the work piece, some times the face end, some times the parting end, note in Gcode to tell me what end to zero
that's why I Z 0 off of some fixed point then do a g54 z offset from the part
I can change a tool and still be set to the rest of the tools
thing is I have a collet chuck for some work a 3 jaw for other work and a 4 jaw for still other work, hard to find a referace point that is common to all
I have one tool I zero, then zero all other tool from that
that can be a pain... I have a collet closer and a 4 jaw chuck but usually don't have the chuck on
I change back and forth lots and yes it is a pain
second lathe comming on line soon to help lower that
so when I zero a tool in EMC does it auto update the tool table?
if you pick Tool Table it will update the currently selected axis in the tool table
in touch off
you do have to have a tool loaded but don't have to have the offset in effect with a G43 to store the offset to the tool table
how do you pick tool table?
from the touch off button it is the last choice in the drop down list
the last choise is P9 G59.3
no tool table
you don't have a tool loaded do you?
guess not, how does one load a tool?
are you using the manual tool change window?
from the MDI?
for tool 1
that will only load a tool and not put the offset into effect for that you need a g43
it's easy once you know how to screw it up lol
some lathe info here http://www.linuxcnc.org/docview/html//lathe_lathe-user.html
so can you have more offsets?
fixture offsets or material offsets or chuck offsets yes
still errors for me on the link, even after refrush
the same info is in your User Manual
you using 2.4?
the top says 2.3.5
2.4 just came out...
* JT-Work wanders to the other shop for a bit
would the auto update update me?
just did a auto update yesterday
hmmm vacuum really is bad for cutting out parts....
parts go down the vacum?
Guess203; you have to change your source list from emc2.3 to emc2.4
parts going down would kill the vacuum
not if it's a wet.dry vac
pretty sure ut would too
part cut = vacuum lost?
use one all the time, if the part gets sucked in, i just open the vac and it's right there :)
I have chunks going down my vac all the time
if the chunk can fit the pipe, it goes down
im not saying vacuum cleaner =)
im saying vacuum as in clamp down
one part cut out = lost vacuum
but the holes shouldn't be big enough for the part to go down ?
so how do I change the source list?
Guess203; System/admin/Software sources
I am there
do an update/upgrade
I have looked all through it and I can not find update/upgrade
in a terminal - sudo apt-get update
sorry i didn't say terminal
then sudo apt-get upgrade
do I need to su?
never use su
sudo takes the place of the need to su
it's literally "su do" - "do this as superuser"
much safer to use than su
sudo rm -rf /
heh.. well, you can still shoot yourself in the foot
read mail, really fast.
all sudo does for you is make you type your password on occasion.
did the sudo apt-get update
nothing for EMC
on a production system with multiple administrators, it creates an audit trail of who has done what to the system... that has a lot of value
even as the sole user/admin of a box, it can be helpful to review sudo logs
Guest203, did you actually change the sources lists?
Guess203; now do sudo apt-get upgrade
on a different note... I want to cut a round cornered rectangle from the inside, working clockwise... that will always be G42 for cutter compensation?
I asked how do you change the source list
ok, that's what I thought :)
i told you
Guess203; System/admin/Software sources
I was there
system/administration/Synaptic Package manager
second tad is third party software
no package manager
in Synaptic, it's Settings/Repositories
look at the list, and change any that say "emc2.3" to say "emc2.4"
the window was to small to see the EMC part
ok, *now* update then upgrade
Now sit back and joy a cup of coffee while standing on your head!
it will not start now
I kept my api file
guess I should have let it update it as well
how do I get it to rewrite the file
so how does one get the rtapi.conf to be upgraded after saying no to rewriting it?
or would that be why I can not start EMC now?
Eric_K is now known as EricKeller
any ideas on how to fix?
straining my memory now
if you start emc2 from a command line it will give more info
open shell, type 'emc'
is shell terminal?
try it and find out =)
invalid coniferation of axis is preventing ENC from starting
can you run stepconf ?
I'm betting that's not exactly what it says :)
yes can open stepconf
if you're trying to run a 2.3 configuration on 2.4, you need to make some edits: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?UPDATING#Changes_between_2_3_x_and_2_4_x
ok miss spelled somewhat
don't think he was talking about the spelling
try loading a sample config, even one of the sim configs
those still load up the realtime stuff, they just don't load any hardware drivers
it was what it said, some other things as well but that looked to be the mail thing
waiting for axis s was tons of times
waiting for s axes
did you try loading one of the configs from the distribution?
Srpski is now known as Dannyboy
so my config file is hooped
one of them anyway
you probably need to remove the NMLFILE setting from your ini file
I thought someone was working on a UI that had a user customizable interface
SWPadnos; so the problem was Guess203 keeping his api file ?
what is an api file?
EricKeller, yes, there is someone doing that, but I don't recall the name of it
don't know ... it's what Guess203 stated
ok, working now
and had tool table open in editor
now sure if tool table open was part of it or now
edit of ini file
thanks a mill everyone, and sorry for being such a pain
you seem to be so excited that you are talking in code.. ;)
I should proof read I see
have you tried treading yet? or not that far?
the cpu is still on my desk, have to write the tool table and rewrite the Gcode before trying to do any cutting
not to mention doing a wack of testing before I try to cut anything
want to make sure I know how EMC uses offsets and how tool table updates work before risking any ouches
here is why you want to understand offsets well http://www.youtube.com/watch?v=G4-lUNa0CpY
all Gcode is for mach right now, need to update all of it, tons of work, there was a reson I resisted the dark side so long
did you here me say "that sucks"
I've done it too
yay for following errors - it just bounces off and stops everything
mine just cost me an insert screw (pop!)
I have to say though, your camera work sure wasn't very good
I was a little shook up after the impact
yeah I bet
any damage? looked pretty innocent.
I just got a divot on the CC-14 holder and some experiance
experience is good!
only if you learn from it lol
glad it wasn't rapiding...
it was a G1 but I had it throttled down some
rapiding towards the chuck/collet scares the hell out of me till I have run a few parts
I mean G0
me too, I'm going to fit a chicken button on the lathe
or as I like to say "A
cnc guys playing chicken, G0 towards thier chucks, the big 3 and 4 jaw ones and see who panics fist
fist of panic
poor panic switch when I am in panic mode, fist slap, smack and pound, just to make sure it got the point of my wanting a stop ASAP
once is never enough
with mach you get the feel the panic more then I want to
Um, that's what a safety relay and BRB are for
BRB = BIG RED BUTTON
that is properly called a BRS
my BRB has seen its fair share of use
there are a few bugs in mach where offset are not stored right
and if you have a program crash ,often, you loose all offset that you did during that sestion with no way to save said offsets till you shut down the program
once I know I did my part correctly I don't worry about EMC2 after that :)
that would be a dream come true
off sets can get messed up just moving around mach the wrong way
I have no worries turning my lathe off and firing it back up and running the same program that I ran last time offsets included
hope to be in your ranks soon
you just have to get a handle on how the offsets are loaded and unloaded etc
archivist_attic : are you "davethearchivist" from youtube?
great video thanks!
can emc do conditionals in gcode?
I watch the four

[19:25:56] <atmega> http://www.linuxcnc.org/docs/2.4/html/gcode_main.html#cha:O-Codes
hmm.. what I really want to do is G41 or G42 depending on a variable, can I just make it G#var?
Xavier_H, I know another user is having a go at the escape wheel method, not heard if he got it going yet
atmega: no, I don't think so. but you can use a negative diameter for one and get the effect of the other
archivist_attic, I have a friend which is clock-maker (http://www.horlogedantan.com/).
He is going to make a similar machine
But I don't have enough knowledges to fully appreciate your work. I just send him your videos link.
What is the CAM software you are using for such work?
I dont know of any cam at a price I can afford that could do it so I have to use inside rear of skull
it helps to be a coder to some extent
you're not realistically going to find a cam program to make escape wheels with a slitting saw, are you?
I wish the gcode syntax was cleaner though
woho I knew I had a piece of cherry wood laying around!
what to do with a piece of cherry wood and a veneer walnut floor board? =)
what to make from it.... hmmmm
I only sniff oak
its really something else
real pine is best
pine sawdust is too stick for me
we used some nice pine to restore the cover for a bell on a building
Someone as ideas to make this run on EMC2? http://www.dailymotion.com/video/x4oi5l_rebull-2_tech?start=1
I think process the velocity vector and orient the blade
in the velocity vector direction
this has been covered over and over - please check the emc-users archives
I am not yet confortable with archive. I will take a look.
but pizza sould be an interesting application!
if you have the g-code or geometry you can calculate the instantaneous velocity vector and orient the wheel. sharp corners at high speed might be problematic...
yes I think at it and I think G0 and "Z" moves can be problematic
I found kinematic solution idea in archive, It is the best way?
not in my opinion. you could not orient the tool at the beginning of a cut before placing it in the material.
ok I continue to devel list
* frallzor is in love with the vectric suite
even the free machinist for their models rock
frallzor, are you talking about pizza cutter problem?
I am reading devel thread on it, no great solution found?
I continue reading
yes great solution is found (use emc's property of linear/rotary coordinated motion to move the rotary axis correctly)
do you have doc?
Hi all, I'm new to IRC and EMC, can I ask about machine homing function now?
don't ask to ask - just ask.
Thanks, I'm Denis, got a 3 axis mill, EMC/Axis v 2.3.5 trying to establish a home position by the home function, axis all move wrong direction
cradek, could you explain me how to do coordinated linear/rotary motion?
I don't fing any G-code which could be usefull for that
by putting both linear and rotary axis words in your G1 motion
or in this case the more interesting case is G2/G3
ok but it is the filter method
But It seems to be problematic with corners
g0 x1 y0 c90; g1 z-0.010; g3 i-1 x-1 c270
if the trajectory planner "cut" sharp angle
but it doesn't matter I don't need such precision!
yes, sharp corners are hard to handle with a knife. ideally you'd want to program a "smooth" path (all moves have tangency). you could get this by putting arcs at the corners.
yes you're right
Guest693: do the axes move the correct directions when you jog?
ya all dead?
SWPadnos: Man, I need one of these near me... http://www.cnn.com/video/#/video/offbeat/2010/05/13/lakhani.uae.gold.to.go.cnn?hpt=C2
the reporter or the vending machine?
when I run out of things to do on the Hardine I'm going to take a nap
for a week!
Oh! sometimes I'm so good I even impress myself. I am the man!
