Need Help! Machine Zero On A Mill Running Mach3 Without Limit Or Home Switches

$

Greetings,

After a few daunting days finally managed to get controls on my mill from some crappy DOS software that wouldn't run properly under XP to Mach3.

It works really well, I just have one problem - machine zero coordinates.

My machine doesn't have home or zero switches so I want to utilize the soft limits. The way I did it today was by jogging the machine to where I wanted to have the zeros manually and just clicking on "Ref all home" then I would just setup the soft limits by jogging onto all of the edges and entering those coordinates into the soft limits. This worked beautifully (especially since I had no kinds of limits whatsoever in the former software, you can only imagine the horror).

Anyway the problem is that when I want to work on something and I import a job into Mach3 and then jog the head into the middle of the table for example and to mark from where the routing should start I have to click "reff all home" again. As you probably can imagine by now, this cancels out my previous zero, the one I want to act as machine zero and uses the new location as both machine zero and the zero for the milling of the new file I imported.

So basically my question here is - is there some way to set a permanent machine zero without home switches. The way I did it works nicely so I'm just looking for a way to make it "stick".

Thanks in advance!
