I'm not a big Twincat user. But if this is a useful tool, it would be a shame if it were forgotten after one post..

Can you share how to create the eeprom content from an XML file?

It says it is an CIA402 drive, so should be compatible.
Maybe someone has a working config to share.
Here is otherwise a starting point github.com/dbraun1981/hal-cia402/tree/main/example
hal and ethercat-conf.xml should be enough to get one axis going. Expand from there.

I agree with you. The topic is not easy.

I had to put the project on hold for a while because the sensor had problems with some heads (precitec) that contain electronic components inside nozzle holder. This effectively prevented my sensor from working.

Now I have dealt with it and it seems to work correctly, so I want to put the device into production.

If you have time and want, I will prepare a test device for you.

I want the device to work at the highest level, so any feedback is valuable to me.

The tests were very promising.

wow, I've had the EtherCat click board lying around for over a year

My problem the whole time was that I didn't have Windows and didn't want to use one.

Now I have found a way to do everything under Linux, i.e. create EEProm from the XML and also flash it via EtherCat, all without TwinCat.

In the meantime I can put my desired config on the LAN9252 and read and write all values via lowlevel spi driver.

only one step is missing to adapt the RIO interface over EtherCat

Hello gentelmen,

how is it with the manual tool change... 

I have sometime issue with precision after tool change +-0.01mm with OWT grinded tool post fixtures with manual toolchange .hal stuff.. I noticed that in the default tool table for lathe is not the waer offsets .. I can switch on them by

where I can define them for the each tool separately 

And then add the the remapping ?

Then I will need to change T1 G43 to T01XX in the postprocessor I think ..

Thanks,

Regards

I'm still addressing some old school electronics that needed updating in the VFD, so turned my attention back to the override potentiometers.
When the spindle runs and I read the pot via the 3.3volt Analogue pin 7i92.0.7i71.0.2.input_03, there is a notable hunting in the spindle speed. Not much, but it just doesn't sound steady.
This is down I think to the ADC hopping between bits which is also normal.
I looked at the original Hurco control use of the pots and how the analogue values were read, and note that the conversion to digital was done in a 12 bit ADC. so the increment between bits is tiny in comparison.
In the 7i73 manual. it states:
"OPERATION
ANALOG INPUTS
Inputs 0 through 7 can read analog signal values however only inputs 0 through 3 are supported for analog input by available interface modes. Analog inputs have a range of 0 to 3.3V. Normal resolution is 8 bits. All bits are readable as digital inputs. Note: analog inputs are only accessible in some software modes."

Does this mean I could configure an analogue input to use a increased resolution of 12 bits?
If so How would I do that?
Thanks
 

Hello everyone,
I'm new to the forum, I just bought two Leadshine EL7-EC400N ethercat driver servo with Leadshine ELM1 AC servo motor 400W to start my new cnc projects.
I installed linuxcnc-ethercat following @Rodw's Ethercat installation from repositories documentation and i created a .ini config lithe axis with two axis X Z, and a hal file and ethercath-conf.xml, but every time I start linuxcnc I get an error 818,
My question is whether the Leadshine EL7-EC400N is compatible with linuxcnc or not?
and also I'm wondering if there's anyone who can help me or give me a minimum configuration (.ini, .hal, .xml) file to make the motor start and get past error 818?
I used rodw's configuration

not sure what you mean by "the position marker's start". A screenshot with an arrow might give us a clearer picture of what you are trying to achieve.
