Yes. It just means that the first axis to hit the switch will latch slowly towards the second axis.

The distance between joint 1 trigger and joint 4 trigger is less than .5mm. I manually stepped want watch each trigger activate.

Negative on each? (I assume)


Ok, this .ini file works. I don't understand.

Joint 1 is HOME_LATCH_VEL = -0.625 and Joint 4 is HOME_LATCH_VEL = 0.625

That doesn't really make sense.
Is there any chance that the two sides of the gantry have their home switches crossed?

Its is my error.

I have two .hal files for the limit switches. One for using a single limit switch on joint 1 and one for testing limit switches on Joint 1 and Joint 4. I did not use the correct file.

My mistake. Sorry about that.

Whenever I've seen the gantry rack on homing, its ALWAYS been due to a wiring error like this.

Yup it was not the wiring, it was the guy (me) who check the pin assignment 3 times and got it wrong three times.

After being reassured by everyone here multiple times the config was ok I knew it was something I was missing.

I am happy to have it working as expected and appreciate the assistance.
