That might cause problems while the gantry is squaring its self during the homing process. Another option might be to use the Near component to monitor either the joint positions or joint velocities, then set an alarm if the difference is too great. https://linuxcnc.org/docs/html/man/man9/near.9.html
I think the encoder ratio component was a tool that was used for slaving before Linuxcnc added the JA branch. (It is kind of obsolete now.) Todd Zuercher P.

Hi guys! I hope you're all doing well, I've had a really strange behavior with my router on the Y axis when homing. Basically one joint tried to move while the other didn't. I could ESTOP the machine before anything happened but this only happens from time to time when homing. The drivers show no error signal and everything looks normal even after the behaviour. I'm monitoring everything before I hit home axes so I really can't track where the problem is. Anyway, I was thinking about using the ENCODER_RATIO component to track both servo motor speeds and trigger the ESTOP automatically when the speed error exceeds a certain amount (I will have to play with that value). What do you think about this measure to at least not worry if the problem persists?
