Allow trim values to be negative to trim up
Fix home_direction to be bool in all cases, lucky it worked using it as int
Add M206 to adjust trim values (in mm) on the fly
Only show endstops that are used (either min or max)
Negate trim depending on homing direction so + trim homes away from home
added hbot/corexy homing
Convert the endstop/homing configs to mm and mm/sec
update sample configs
Old config values in steps and steps/sec will still be accepted
add corexy_homing to sample config
udate delta config for homing
turn off both motors when endstop is hit for corexy
check both corexy motors for stop
remove last debug printf from homing
