Actually I fixed the web page but Dream Host keeps serving up the old page and I don't know why...

I figured out that Dreamhost changed servers on me and that's why the web page was not updated.

Someone has test this servo drive ?
servo ethercat A1-SVD-15A-3MX from Hltnc

Folks,
I am trying to go from the Axis interface to QTDragon.

I have QTDragon running but, I can't HOME any of my axis. Is there a simple setup/install document that I should be using?
I just created a new PNCCONF and then and pasted from my Axis ini and hal files and worked out the differences.

I've noticed a big difference in size of INI files between the two interfaces

Attaching my config files.

Thanks in advance!

 

I thought I fixed those... and it was a typo on my part for the link.

Hi!
I am working on two projects a Roland camm 1 and a LKPF protomat 60C which speaks HPGL. I am wonding if you ended up using Linuxcnc and how this works for you?

Best regards,
Adrian

I refer here to main branch of linuxcnc 2.10 (master or devel) and it works with Xenomai 3. 

You done everything correct but apart building LinuxCNC to Xenomai the LinuxCNC at runtime checks if it has Xenomai kernel.

In order to fix the issue you must edit file: "linuxcnc/src/rtapi/uspace_common.h", around 386 line of code you find:

#ifdef USPACE_XENOMAI
static int detect_xenomai() {
    struct utsname u;
    uname(&u);
    return strcasestr (u.release, "-xenomai") != 0;
}
#else
static int detect_xenomai() {
    return 0;
}

As you see to check what kernel you got it uses very well known "uname" function. The problem is that at the moment Kernel build with Xenomai (new versions) and checked with "uname" does not include word "-xenomai" anymore but from what I know it has "IRQPIPE". That is what I got. Change what requires to be changed, recompile linuxcnc run again and... happy days.

It took me a while to figure that one out when I was compiling mine so I save you headache.
Probably that change should be commited to git 
 

what the hell is wrong with me

but i have a serious problem with the kinematic, i need only 4joints, but the melfa stuff have 6
don't know how to setup a 4dof robot the right way

Hi
i test this on my Machine and i think your UDEV is wrong.

---

My Inputdevice:
I: Bus=0003 Vendor=04b3 Product=3025 Version=0110
N: Name="LITE-ON Technology USB NetVista Full Width Keyboard."

---

Add this to your UDEV File ---- change the id´s to yours.

ATTRS{idVendor}=="04b3", ATTRS{idProduct}=="3025", GROUP="plugdev" ,MODE="0666"

Then open a Terminal make the following commands... with your naming

sudo adduser cnc plugdev
sudo udevadm trigger
halrun
loadusr -W hal_input -KRAL LITE
after that i get this
note: name is 'LITE-ON Technology USB NetVista Full Width Keyboard.'
halcmd: Note: Using POSIX realtime


I get no more permission warnings.

Here a Video from my testing today.....

Note that in the 'modified' DH-System the angular rotation (ie 'ALPHA-n') is always applied before the 'A' and 'D'.
IIRC this is different from the standard DH-system.

Ok, once I figured out that it wants to be pointed to the melfa_dh.hal I got it working.

$ python git/linuxcnc-robot-logger/dh-parameter.py linuxcnc-292-feb/configs/sim/axis/vismach/melfa-sim/melfa_dh.hal

Looks nice.
I don't have much time just now but here is something not quite right in the way the D-parameters are applied. A-offset values are always in the direction of the current X-axis and the D values along the Z-axis. This is correct for A-0,D-0 but the D-1 value is applied in world-x-direction instead of the current-Z-direction (which at this point is pointing in the world-y-direction.)

Have you seen my documentation:
linuxcnc.org/docs/html/motion/dh-parameters.html

Try here
github.com/jethornton/mesact/releases
download the deb for what you are running (usually amd64) and double click on it after the download finished, install, run, enjoy.

is there a reason all the links are dead? i keep getting the 404 error. when i wget the .deb file Resolving github.com (github.com)... 140.82.113.4
Connecting to github.com (github.com)|140.82.113.4|:443... connected.

Excellent! That would be greatly appreciated @hmnijp 

@grotius,  I don't want this to hijack your thread in anyway, so let me know if this testing is helpful or if it is noise in your working thread and I will gladly move it elsewhere if so desired. ( I suspect it may be helpful, especially establishing baselines and real world testing on machines with speeds higher than stepper motor machine with ballscrews.  my machine is not crazy fast but it is faster than most stepper dovetail conversions and has some mass too it ~6klbs with xy rapids of 708ipm and cuting feed rates maxxing out around 200ipm.  

I am camming up a test part that doesn't waste too much stock material for each testing and would be happy to take input for features that would be good to test.  I would gladly run the test using different trajectory planners, post processors, settings etc and film it. just let me know!

High everybody,I’ve got a problem with HBS57H driver board , made by maybe ECON Technology in China.I would like to communicate with it so I’ve hooked up with PC with a DB9 – RJ11 cable.I have already tried with Longs Motor ProTune program, and I’ve monitored the COM1 port withSerial Port Monitor by ELTIMA.  I was seeing the communication on he COM1 port, but at the endthe status of the driver board was not connected and the port was closed.I’have tried out with ECON Chinese program, but than I’ve not seeing anything on COM1 port, and I was not able to communicate with the driver modul.I would like to know the pinout of the DB9-RJ11 cable, because I’m not sure of it.And maybe something information and solution for HBS57H driver modul.I've not hooked up the motor for the driver board, because at the moment I just want to communicate the driver board and read out from it the settings.Thank you
