EtherCAT + 7i96s + Internet Success was created by santy
Hello everyone.
I managed to get 3 separate NICs in a Fujitsu Desktop with a PCIe adapter, and now i have successfully connected to EtherCAT, Mesa 7i96s, and the internet simultaneously.
I have done this to move a XX,Y,Z gantry. I have 2 motors for 2 Z axis, which will work independently in 2 separate Qtplasmac configs.
I have created a simple 7i96s config from PNCCONF, and tried to adapt it into my CIA402 config. There have been some errors in trying to boot QTplasmac, because i keep getting different errors like the following.
I have to comment this line otherwise the system doesnt boot.
when i comment that line out, the config almost starts but then i get this.
My main goal would be to start the config, and double the X axis signal into 2 motors, altering the cia402 config.
basically get a main axis and a tandem axis with ethercat, which will have 2 home input from the mesa card.
remove the problem of having to comment out the line which provides plasmac z axis position *listed above*
get 2 different Z motor driver slaves to run for Z axis, one for one config, and one for the other
Startup QTplasmac and finish my config according to the machine
Could anyone provide some tips in the right direction please ??
I attach my config below.
Thank you
best regards

The motherboard has no onboard LAN?
Weird.
Your latency will likely be really bad because you have so many extra PCIe cards and stuff.
The latency of 2 identical NIC cards will likely differ slightly, especially due to different bus positions on the motherboard, which might cause issues with synchronisation.

Python gives very unhelpful errors and traceback.
+1 for Java!
Did ya try the wizard?

Looks like it is missing a value for the OFFSET_AV_RATIO variable, doesn't it? Should be 0.5 I think but check the QtPlasmaC docs.

This is why defining variable types is such a good idea.
It avoids issues like this.
