Problem with Gantry Homing

Hello everyone! I have a problem with gantry machine homing procedure. Two motors on one axis doesn't do the last synchronized final move in the same time. That means, when the first one touches the limit switch, it starts backing off, without waiting for the second one.

If i'm not mistaken, it should work like in this video:


This is the tutorial i used to set up my gantry machine:

Here are my configuration files:


Where did i go wrong? Maybe i misunderstood something?

linuxcnc.org/docs/devel/html/config/ini-homing.html

The initial HOME_SEQUENCE number may be 0, 1 (or -1). The absolute value of sequence numbers must increment by one — skipping sequence numbers is not supported. If a sequence number is omitted, "Home All" homing will stop upon conmpletion of the last valid sequence number.

I think -2 is not valid.
If that does not fix it, I would also check your limit and home switch wiring is correct. When I've had issues like that it is because I've had something incorrect.
Also using very slow homing velocities helps isolate problems as you have time to see things happen.

Thank you for your replies, but it seems the problem is gone by itself. I just misunderstood the way homing process functions.A joint goes to the limit switch, then back until it opens again, waits for the other motor does the same and only then they both make the final move. I only realized it when i made a proper test installation with actually working two stepmotors (before i used hal scope and dro). So yes, now it's working as it meant to be, nevertheless the documentation for homing sequences isn't too friendly for beginners
