Description:

Increased from 300 to 1000mm.
There was homing timeouts if you used 500mm rail or longer
This now matches a timeout of 30s and balances flexible use case and convenience for average user.

The math here doesn't check out.
30 sec homing timeout, 25mm/sec homing speed = 750mm total maximum movement before hitting timeout.

That would work for a max length (now set to 750mm) rail that starts out with minimal distance to get to full extension before homing back to find zero, however if the rail were in a mid point, it would extend, then not have time to fully retract before hitting 30s timeout as the total distance moved would exceed 750mm.

Might not be worth changing the timeout for, since this would be edge-case, but worth pointing out.

TRUE 500mm support I believe maths out to need a worst-case of 34 second timeout @ 25mm/s assuming 75mm of travel is lost to OSSM head and tensioner/end effector
