Easel Home position aka Work Zero/MaterialZero (Easel 0,0 Design position) is stored as an offset value like “3 steps north, 3 steps west and 4 steps up”. (Same applies for G28 & G30 parking spaces)
To have a consistent destination to arrive at you need a known start point. This is what homing switches do.
They provide a consistent reference point, so the “3 steps north, 3 steps west and 4 steps up” ends up at the same spot.
These offset values are stored and will be kept between power down/ups. Until changed.
So when you have 15 identical pieces to carve:
- 1 - make a bump stop for the first one and position Piece#1 up again it.
- 2 - place your bit at you intended work zero (Easel Home Position)
- 3 - Carve #1, jog the bit out of the way to remove #1 and insert #2
- 4 - Click Carve and “Use previous Home” and #2 will be done.
- 5 - Repeat for #3.
Should your machine loose position or for whatever reason abort, redo your homing cycle and start at bullet 4
