For timing critical applications you would probably want to avoid anything python and use C/C++ instead.
I would try to use a C HAL component to get the required values into hal, then use the motion.digital and motion.analog pins and use M66 to wait for the respective values in a running gcode.

I had a similar problem. Have you tried manually downloading the network driver? There are instructions on the web how to load them manually.
The other thing you can try is to remove the flash drive and reload.

I have explained everything in last post. With update list.

1. Estop working. (Made mistake of defining as "estop pin")
2. Encoder Working. ( Used conv_float_s32 function)
3. PRU_Frequency = 12000. Working good with speed of upto 2400mm/min.
4. Jog scale slow. Its about jog and axis selector switch. ( I found its a problem of board pin compatibility issue. May be those pins of EXP1 has some interference and not suitable for inputs) So I changed to inputs to elsewhere and problem resolved. Pins of EXP1 was giving problem. I tried pins of BL_touch. That also had delay in input switching. So I changed location of pins and issue resolved.

Problem... ""setp encoder.0.position-scale 400.0"" if I change this value to anything else then also it changes nothing. Per click of encoder value is always same. I tried 100-2400 value.

If you have some time please have look at my previous post with updates.

I have attached PIC of new pin location. 

What BIOS options do you have under "advanced frequency settings"?

Bios setup, tmax and packet error data attached in previous post. Please look into.

bios setup attached in photos.

kindly suggest what changes to be done.

also do you have customized python files in your config or are you using the latest python files included in the sim folder?

@PeterSi

can you join the qtpyvcp chat on matrix?  will be much easier to help resolve this then we can posat the findings for others here.

thanks!

Chris

Thanks a lot for your nice link,I'll study it carefully.

Thanks ,separating the text translating and the source code will be a improvement for the codes level ,nice job!

The representative from Lichuan told me that the company has assigned engineers to work out the LCNC EtherCAT compatibility issues. I have sent them a few configurations from other LCNC EtherCAT examples and explained how we managed to get the servo to run. I’m new to LCNC and have zero knowledge of EtherCAT and won’t be able to help any further. If there’s anything you want to pass along to the engineers, such as documentation and configurations, or if you have any questions for them, including questions about missing information in the documentation, just leave them on this thread and I’ll pass them along.

sorry, it is hard to keep track of everything

""setp encoder.0.position-scale 400.0""
yes, sorry i forgot its quad, you are right to put 1200 like in your file

lets make a list then

estop = good?
encoder = good?
PRU_freq 120000 = good?
jog scale = slow

im not sure why you are getting a delay. I use the pins on exp1 for my encoder/limit switch stuff usually, and i havent seen a delay before.

i cannot run qtdragon on my machine, so I only copied over mpg hal. I am not seeing any delay in the IO or on the mux. Where are you seeing a delay? For the qtdragon gui to change ? When I use halshow, they are responding instantly

start by doing this


 

Pushed a development screen/sim config to master branch (2.10 pre)
Look for qtdragon_lathe
Early days of course..

Ok I see my error in the command for the core info and it showed 1,3 like in the other post. Now I just need to learn how to make the change in the grub file to see if that changes my Latency issue. One step at a time. (: (:
