General Mach Discussion / Re: soft limits and active coordinate system question

Hi,
soft limits only make sense when the machine is referenced or homed.
Your original parallel port device would retain the machine coords from your last session and provided the tool
position has not moved it will retain a 'close enough reference' from the last session and therefore the soft limits
are 'close enough' too.
In fact over successive sessions the reference will slip and therefore your soft limits will also be inaccurate.
The correct procedure is to Home your machine every time you start up.
That is what you USB controller is expecting.
