- Updated new homing cycle to error out when a pull-off motion detects the limit is still active. - Created a limits_get_state() function to centralize it. It reports state as a bit-wise booleans according to axis numbering. - Updated the print uint8 functions. Generalized it to allow both base2 and base10 printouts, while allowing base2 prints with N_AXIS digits for limit state status reports. Doing this saved about 100bytes of flash as well. - Applied CoreXY status reporting bug fix by @phd0. Thanks!
