IO Questions around mixing IO between Ethercat and Pi 5?

Category: EtherCAT

Hello zmrdko,

I just found your great work with the easycat card.
I'm starting to play with it, and it works great for digital input and output. With 1 encoder, no problem.

However, with 2 or more encoders, it doesn't work... As soon as I change the "QUADENCS" value to greater than 1, I can no longer connect to the easycat card. I get an error with the "easynavigator" software.
Have you ever had this problem?
Do you have any leads?

regards
Laurent

Tool Change

Category: Configuration Tools

Hey guys...
I'm using Linux for the first time for a lathe with a turret with eight tools, each in its respective position, sending an individual signal for each position and a turret locked signal.

Working cycle:
"Control system sends signal of tool change -->Motor running with positive rotating -->Toothed disks is disengaged -->tool holder disk rotating-->tool holder disk locating-->Control system receives the signal of tool holder disk locating and sends the signal of delay time of motor reversal rotating Motor running with reversal rotating -->Toothed disks is locked-->Delay time of"

I need to know if there is any component in Linux that supports this cycle, or if someone has already done something similar so that I can use it as a basis to create the tool change cycle.

Amazing! Thank you! 

I don't know the history of the board. Bought it cheap on eBay many years ago. It would be great if I can manage to use it, if not a 7I96S would probably suit my needs better.

Thanks again,

Dan

Probably. At least I could reproduce it this way.


The issue here is that using 'halui' in parallel to a gui is not really a very good idea at all. Many do it, myself included, to connect panel buttons. Gmoccapy is designed to use button rows aligned with the gui buttons but that is not always practical.

I wonder if it would make sense to have gmoccapy create its own dedicated pins like 'halui' so we would have more control over them.
