THere is a topic on the forum that explains but I am not logged in to link you to it. Its probably in this thread anyway.

I think there is an error where you load your xml file in hal
Do you have this in hal?
loadusr -W lcec_conf ethercat-conf.xml
loadrt lcec

you probably need to modify cia402.comp and somehow allow you to set the controlword from hal (probably from another pin)
What are you trying to do? 

Can you post your config files?

So It sounds like you are seeing parts of your code that are not reaching the programmed feed rate because of short line segments and acceleration limitations, but when you slow the feed override then those acceleration limited areas don't slow down the same as parts of your code that were not acceleration limited, is this correct? And you are asking for all parts of your code to slow at the same percentage regardless whether it was able to move at the programmed feed?

A few years ago, I built a HyperCube EVO 3D printer, which still works perfectly to this day.
Thank you!
I accidentally came across this thread and immediately thought that it must be something good. Regarding 3D printers, I have some boards based on an LPC processor. I did a few tests with SPI but gave up because I saw it was a dead end...
I have a question: Which controller is the best to buy at the beginning of 2025? Which one is the fastest and the least problematic?

i tried re installing again and now i have this new error instead

Thank u very much, it worked.

the files u shared should come with qtvcp install and your information should be in the qtvcp documentation, thanks again.

I can dive in to UI designing now, qtvcp is written in a way that u design the general layout in qt and finish the design by styling it with .qss file right?

I want to make the design like the attached UIs, graphics can be done in qt directly or .qss is a must?

if so, can u add animations to .qss which can be played one time during launch of the ui for example?
 

Ethercat on its own works fine a reads the slaves the issue is with the driver i think

I got a new pc setup and tried downloading ethercat i followed the guide thats on the forum but i keep getting this error any help would be greatly appreciated

Ok, apparently I just needed to restart the Sensor couple of times in a row and now I started to see the data. The topic may be closed.

Cheers,

Mine mesa ethernet card has interrupts on cpu0 how can move it to cpu3 isolated for linuxcnc ?

Thank you for looking at the design. Always good with new insights.
I can go with another resistor for added safety. Looked around a bit, and that will require a bit deeper study it look like. Not so easy to find in the sources I use. The most professional source I use is tme.eu. The only wire wound resistors at 100 kOhm they had would just fit in my hand.
Today, the resistor is chosen to operate with 500V, and 100kOhm is chosen for the heat output it generates.

I was thinking about the high voltage aspect when designing the board.
In this view you can see the short wire between the connector and the resistor. As I see it this will act as a fuse and blow out at high currents entering the board. Isolated area around the voltage parts. Hopefully any damage and malfunction will stay on the left side of the isolation barrier.
That's also why I am redesigning it.The intention was to have the ground planes electrically  connected to the work piece. As it is now the ground planes are connected to the electrode. That small image is from the new design, also the high voltage part of the resistor tucked away behind the connector so shouldn't be very easy to reach with fingers.
 

The parts cost of one mini-board is around 10 USD/EUR so replaceable. I don't want a failure on the mini-board to break the EtherCAT board though, that's a bigger deal if that happens.
Thanks again for giving my brain some exercise.

So a new design has been made - thanks to an electronics engineer who helped - with reversed polarity for the torch voltage, well, everything is internal to the board. Should be safer, better. Just ordered new circuit boards. Somewhere after March 10th they might show up.


 

Hello again, guys,
I was wondering how to send the control word. I know about the transmission in the configuration file through cia402, but I need to send a specific value for the control word, not just set up the connection between them. Can you tell me where the signals are generated in LinuxCNC so that I can send a specific value? If I turn on the machine with a button, why doesn't the control word value change? Please explain to me not where the signals are sent, but how to send a specific value to the control word. Where in Linux are these signals generated, and how can I set them up for a specific driver? At what point do I need to inform Linux that the driver should use the control word 0Fh? I need to insert 0Fh into 6040, but it doesn't seem to work. I have the following pieces of code written:
sodick.hal:

#from cia402 to servo(ethercat)
net 4-controlword              cia402.4.controlword => lcec.0.4.cia-controlword

ethercat-conf.xml:

      <syncManager idx="2" dir="out">
        <pdo idx="1600">
          <pdoEntry idx="6040" subIdx="00" bitLen="16" halPin="cia-controlword" halType="u32"/>

I had a look at that too, but it seems to be quite limited in functions just for jogging and only one axis at a time..., my teammate is having a deeper look into it though maybe he might find something, thanks for the tip!
