Thanks Dave and Marius! Dave so this is different than table travel from stepconf axis config?:
MIN_LIMIT = -1000 - The minimum limit (soft limit) for axis motion, in machine units. When this limit is exceeded, the controller aborts axis motion. MAX_LIMIT = 1000 - The maximum limit (soft limit) for axis motion, in machine units. When this limit is exceeded, the controller aborts axis motion. Marius so I will set home back to 0 for xyz in stepconf axis config. So if I have: X axis table travel 0 to 550 home 0 Y axis table travel 0 to 400 home 0 Z axis table travel 0 to 60 home 0 Does that seem correct? Where would the negative values I have seen in example screenshots be relevant to table travel? If the above values are correct what would my values be for MIN_LIMIT MAX_LIMIT, I am also confused about the use of negative values, the MIN_LIMIT example above is -1000? Thanks again.
