[Emc-users] Something that bugs me
Greetings; It appears that /usr/bin/halui has never been edited and rebuilt since a long time back. When the camview-emc stanza for [HALUI] is added to the ini file, I am getting a whole raft load of errors because halui can't find stuff it is apparently hard coded for, starting with the use of the emc naming convention. Is there a fix? Or, since I don't know where this file comes from, is it camview-emc's responsibility? Thanks.

Re: [Emc-users] (no subject)
Aaron When you cut stuff with a lot of little cuts, especially curved cuts, the speed will always be slow. If you look at the constant velocity parameters of any CNC machine you will find that the machine has to accelerate and then decelerate again at the beginning and end of every cut or move. Unless you have a very light gantry with a huge acceleration, you will have a slow response. When the cuts are very short the machine does not have enough time to get to the requested feed rate before it has to slow down again. It is one of the pains of cutting 3D stuff.

I am trying to cut a helical final cut, which seems to have lots of tiny moves, but other files I have tried are almost as slow. Can any one offer some advice? The lots of tiny moves might be the problem. What is the acceleration on the rotary axis? Is it anywhere near the actual physical maximum? You simply might not have increased the A-axis accel enough. The scaling on rotary axes is such that you can end up with some very big numbers indeed. Consider a direct-coupled 5mm pitch ballscrew, and a direct-coupled rotary axis both coupled to a motor that can accelerate at 25,000 steps/sec/sec. That gives you a linear acceleration of 625mm/s/s or 25 inch/s/s or 45,000 degrees/s/s. Even geared 30:1 with a worm gear your rotary axis acceleration is likely to be twice the linear accel in mm or 60 x in inches. (and that was assuming no gearing between the motors and screws). The reason this matters is that LinuxCNC likes to be able to stop by the end of the next move (this is because it doesn't plan beyond the end of the next move, which is something being actively worked on at the moment). How fast will a simple G1 X500 A7200 run? If that runs good and fast, then that is a sign that it is lookahead related, and lookahead issues are made much worse by low acceleration values. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto -- November Webinars for C, C++, Fortran Developers Accelerate application performance with scalable programming models.

On Saturday 09 November 2013 10:11:49 Marius Liebenberg did opine: I don't think it will help as the problem is acceleration over distance. I.E. Distance of move to short to reach max feed rate. The other problem no one has mentioned is that his LCNC machine is old slow, however the OP did not mention the base_thread times from his ini file. Or his microstep ratios if he is using steppers. I ran into this while exploring the merits of running my 2M542 drivers at higher microstep ratio's. The atom board, running a base_thread of 23 microseconds, is simply incapable to issuing enough steps per second to be able to hit the motors maximum speed capability when the microstep divisor is more than 8. At 8, and a 2/1 gear between the 425 and the Z screw, I can move Z on the lathe at 60ipm. At 8, its noisy, I think because I may not be on the sweet spot for motor currants so the thou or so gear lash in the 2/1 takes a beating despite the damper on the motor. Some day I may convert it to belt drive just because of that. At 16, it drops to 30ipm regardless of what else I set in the ini file, the 23 u-sec base_thread cycle is tapped out and can't issue the steps fast enough. So my question to the OP is: What is your base_thread period, and your microstep rate? On 2013/11/09 01:47 PM, Belli Button wrote: I think LCNC can only execute one Gcode per servo cycle.

Re: [Emc-users] (no subject)Rotary problems
Aaron G64 will have some effect but I cannot say how much. The amount of moves are really determined by you cam software. Some people do an aggressive roughing cycle to use as little time as possible and then they can afford the time spent on the finishing cut. What you can try is to make your acceleration faster. Remember when cutting complex 3D stuff the speed of the move is only as fast as the slowest axis on the machine. On 2013/11/09 03:14 PM, aaron moore wrote: Marius Thanks for your replymakes sense.

If you look at the constant velocity parameters of any CNC machine you will find that the machine has to accelerate and then decelerate again at the beginning and end of every cut or move. Unless you have a very light gantry with a huge acceleration, you will have a slow response. When the cuts are very short the machine does not have enough time to get to the requested feed rate before it has to slow down again. It is one of the pains of cutting 3D stuff.

It currently works only for paths cut in XY plane using XY movements. I

My setup is a rotary system so I need to convert all cartesian XYZ

Nice pattern. I'll include it, but may alter the formulation of the code
a bit (see below).
I am really excited that the grammar performs this well :-)

the Z axis. Instead of move emitting g1 X?? Y?? Z?? I need to emit g1
x?? C?? Z?? . I am not sure how to do this. I havent looked yet in

you have for creating a polar version of the goto and move functions.
The current gcmc version uses a 6-axis system XYZABC in the vectors to
move/goto calls. Arcs only use XYZ.
However, there is a bug that fails the output at the moment because the
ABC axes are converted to mm and not to degrees. A fix is in git (and
pushed to gitorious).
To move in a XZC axis system, you have vectors that look like:
vec = [x, -, z, -, -, c];
An additional fix is in the pipeline which includes a 9-axis system
XYZABCUVW, where XYZ and UVW are distance based and ABC angular based
(also pushed to gitorious).
A few comments on the code.
You write:
function CreateWheel(r,s,p) {
local w;
w = [r,s,p];
return w;
}
It could be simply written as (faster at runtime):
function CreateWheel(r,s,p)
{
return [r,s,p];
}
FWIW, you do not need the function as such... You call it with explicit
addressing as:
wheels = {};
wheels[0] = CreateWheel(10,1,0);
wheels[1] = CreateWheel(5,7,0);
wheels[2] = CreateWheel(3.333,-17,90);
I would have written:
wheels = {};
wheels += { CreateWheel(10,1,0) };
wheels += { CreateWheel(5,7,0) };
wheels += { CreateWheel(3.333,-17,90) };
or
wheels = { [10, 1, 0], [5, 7, 0], [3.333, -17, 90] };
Both alternatives have the advantage that you do not need to keep track
of the indices yourself. However, the latter may be more difficult to
understand. There are more ways to come to the same result.
Something not documented correctly (or not extensively enough) is the
conversions of sin() arguments and to_XXX() functions. You do explicit
radians conversion in CalcPoint() using to_rad().
If you have defined the angles from the start, then the conversions will
be implicit in the grammar:
wheels = { [10, 1, 0deg], [5, 7, 0deg], [3.333, -17, 90deg] };
...and...
CutPath(wheels, 0deg, 0.01deg, 360deg, cuttingdepth, svec);
The sin(), cos() and tan() functions will internally convert from
degrees to radians before calling the underlying system sin/cos/tan
function.
Your example has made it clear that I need to implement a vector
slice/combine operator to isolate and combine XYZ, ABC and UVW parts of
any vector. Also shift/rotate must be implemented for vectors (I already
did that for vectorlists). Such operations would help vector
calculations in some instances. Alternative is that a final calculation
must do coordinate-system conversion, but that may be quite hard as it
depends on the physical setup of the target.
Some input on axis conversion and geometry conversion calculations and
options is appreciated to find a generalized and easily comprehensible
solution.

I made some small changes to the code. It runs a bit faster than the
original version.
Please note, gcmc 1.1.1 cannot compile it, you need version 1.1.2 or the
git version. Version 1.1.1 lacks the ability to accept function calls as
arguments in the creation of vector-lists (dies on an assert()).

Re: [Emc-users] Converting a Euro placer pick-and-place machine to LinuxCNC

Anyway, my Philips CSM84 works well, but I do miss having the accuracy of a vision system. If it eventually croaks, it might make sense to add cameras and see what I could do in the area of a retrofit with modern technology.

Re: [Emc-users] (no subject)Rotary problems
Aaron, Marius L. is right about current LinuxCNC behaviour, but I would not say so about any CNC machine when you can let some amount of error in your toolpath, what G64P..Q.. (BTW, I suggest using Q parameter too) should do, but it does not do much in LinuxCNC and your case actually yet. This is because it is limited to 2 moves of look-ahead only and keeps velocity low to be able to fully stop the machine at your set max accel values after those two lines of G code. This is like driving a car in a dense fog. The car could go much faster, but you can't because you don't see further safe distance you want to be able to stop. (Just a thought: how you could drive it if you would know by 100% there is nothing on your road?..) To be straight, when I started using LinuxCNC (came from industrial machines, then Mach3 world which has big look-ahead capabilities) and I understood LinuxCNC look-ahead limitations, I was really upset. Maybe this is because I deal with 3D free-shape milling tasks mostly, which do have a lot of tiny segments, which make the toolpath and people who run those machines do count time as money.. But LinuxCNC people are trying to solve this problem and there are beta solutions in testing now. Look at thread Tech demo of circular arc blending on devel group. They got impressive results. And I can say this is the thing I am hoping and waiting from LinuxCNC most. And I hope it will not be limited to two or three axes / joints.. Another thing to try is NURBS G command. Marius Alksnys aaron moore aaronmo...@linuxmail.org wrote in message news:20131109131423.172...@gmx.com... Marius Thanks for your replymakes sense. Does G64 p# work on rotary files/systems? It didn't seem to when I ran it. Do you have any tips for reducing the numer of moves in a job? Sorry. I forgot to put a subject up top, Aaron - Original Message - From: Marius Liebenberg Sent: 11/09/13 11:17 AM To: emc-users@lists.sourceforge.net Subject: Re: [Emc-users] (no subject) Aaron When you cut stuff with a lot of little cuts, especially curved cuts, the speed will always be slow. If you look at the constant velocity parameters of any CNC machine you will find that the machine has to accelerate and then decelerate again at the beginning and end of every cut or move. Unless you have a very light gantry with a huge acceleration, you will have a slow response. When the cuts are very short the machine does not have enough time to get to the requested feed rate before it has to slow down again. It is one of the pains of cutting 3D stuff.

I have tried editing the code and inc reasing feed and acceleration in the ini file to increase the speed, but in makes no difference. I am trying to cut a helical final cut, which seems to have lots of tiny moves, but other files I have tried are almost as slow. Can any one offer some advice? The computer I run Lcnc on is very old an slow, does that have any bearing?

Re: [Emc-users] Way to control 6 axis robot, jerk limitation. Araisrobo?
Hello Marius, On Thu, Nov 7, 2013 at 9:36 AM, Marius Alksnys marius.alks...@gmail.comwrote: I am using MESA 5i23, 8i20, 7i49 (resolver card). I have 7i43-P (but without USB). Now I have even more questions: Isn't it possible to run some simulation without a hardware? For simulation, run linuxcnc with './configs/sim/axis/axis_mm.ini' Are these S velocity profiles realised in hardware only? If not - how to use them without this usb to 7i43 solution? It is implemented in tp.c ; therefore, it should be able to run with other hardware. Is it possible to use S velocity profile feature in RT linux? If yes - how? Our branch is not verified with RT linux. I wish to merge with Michael's Unified Build work to resolve this issue. Would it be hard to implement other types of outputs from 7i43 to control servo drives, for example, 3pwmgen for direct bridge control for 3 phase permanent magnet synchronous motors (or BLDC)? We control this type of motors with A/B phase pulse train. The PWM for velocity or torque control mode is under development. BTW, there are things to consider / fix in your wiki page: 1. Descibe the base where to start from - a lucid distro, freshly installed from a CD or master branch or precise. If precise - how to make / get one - from generic ubuntu or from linuxcnc + upgrade.. At this time, we support precise (ubuntu 12.04) only. 2. I got error running line git clone https://github.com/araisrobo/linuxcnc.git;, telling me that directory linuxcnc already exists.. Please try this: git clone https://github.com/araisrobo/linuxcnc.git linuxcnc-araisrobo 3. Correct ./autgen.sh to ./autogen.sh Thanks; it has been fixed. 4. Explain how to run linuxcnc every time.. We usually start a terminal, change to corresponding *.ini path, and start linuxcnc with linuxcnc INI-FILE.
