I haven't pursued this yet, but it may be that soft limits won't work properly if you don't setup and use the same machine zero at every power-up. I tend to think that machine zero and part zero are different things. There are features and procedures to handle both. It seems that even if you don't have hardware limit switches, it would be best to forgo a bit of convenience and get into the habit of using your machine as if it had hardware limits. Soft limits may not be important for a Sherline class machine, but you can start to break things with bigger machines when you overrun limits. Getting up to speed with this, is on my roundtoit list.
