Usually, all of the parameter values from DOWNL.OAD (and, optionally, LKCMM.CFG) are read in, and then the machine is initialized and possibly homed. Setting the NewInit entry to True is useful to deal with installation difficulties. This option changes the behavior so that DOWNL.OAD is read one line at a time, with each command immediately executed. In other words, the file is treated like a script (as LK does) rather than a value data file.
If the machine does not need to be homed, any homing command (such as #XZ) is skipped. You can use the NewInit entry to edit and experiment with the DOWNL.OAD file to change the initialization sequence for the machine.
