Hello everyone, I'm working on a new project and need a specific firmware for my 5i25T card to interface with a 7i85s daughterboard. I've searched the forum and the official LinuxCNC repository but haven't found a configuration that fits my requirements.My setup needs to support:
  • 4 PWM Generators 
  • 4 Encoders.
     
Also, could someone clarify the correct pull-up or pull-down resistor configuration for the 5i25T board when using it with the 7i85s daughterboard? What are the correct jumper settings (W2, W4) for this specific setup? Thanks in advance!

I'll try and to do this this evening.

The default (pullup) configuration is suggested for Mesa daughter cards
