I’ve done it by using something already cut as a reference point.
Assume I was cutting the text “Billy The Kid”
That entire text would be in estlcam, but on the first cut, I would put the zero at lower left of work and only put cuts up to maybe the “T” so it would cut “Billy T”. Create the G-code for that and cut.
Then I would would create the paths to follow only “he Kid” but now set the reference point to the upper right corner of that “T” that I already cut. Of course, I slide the piece to the left to where that corner is near my left most cutting position. Next, manually align the cutter to that point, then start the 2nd cut of “he Kid”.
You will need some kind of fence that allows you to slide left/right without moving the piece up or down. I clamped an extra board to my table. It could be on top or bottom side.
This method worked for me, but I would like to hear if there is a better method.
