Hard Limits

[maskedpirate]

I've recently ordered the Masso G3 and I'm reviewing the documentation while waiting for it to arrive. A few questions about limit sensors:

• Can the "Home Sensor Inputs" also act as hard limits?
  • I currently have all NPN proximity sensors. I understand I can invert inputs, however since you cannot really combine multiple NC sensors (X--, X++) into a single sensor, I'm hopeful the home sensor can act as X--, and the Motor Aarm Input acts as X++.
    
  
  
  
• I have a dual Y axis drive and intend to slave B to Y so I can auto square the gantry during homing. I'll have separate home sensors for B & Y as described by the docs. How should the homing sequence be configured? Does one of the sequence lines need to include Y and B checked, or once B is slaved to Y, will selecting only Y accomplish the squaring.
  

Thanks!

yes, all homing inputs automatically act as hard limits, please see this: https://docs.masso.com.au/wiring-and-setup/setup-and-calibration/soft-and-hard-limits

When slaving axis, you will see that once you slave the B axis in the B axis settings window and then goto the homing settings, the B axis is disabled in the homing sequence and you simply need to select the Y-axis for homing and B axis is automatically homed.

Thank you! Appreciate the updated documentation page too.
