Desc	XPS Controller	Motor name	Channel	Position	Desc. position
Alignment Target Vertical UP/DOWN	XPS:LI20:MC10	PB11 SFQED Target Vertical	M1	0/99	Home position, needed when inserting or retracting OAP assembly. Do not drive to home (0) when MO tower is in IN position. /Clear position with and without OAP assembly. Moving assembly requires moving out of clear position.
MO Tower Mover IN/OUT	XPS:LI20:MC10	PB12 SFQED Tower Mover	M2	-98.1/0	IN position to look at focal spot. Clear (retracted), also home position, needs to be done before retracting SFQED assembly
OAP Assembly IN/OUT	XPS:LI20:MC10	PB16 SFQED Assembly Removal	M3	118/0	IN position to focus main beam. Clear (retracted), also home positions, needs MO Tower to move out first, also needs Alignment target to move upwards first
Elliptical mirror/M3 IN/OUT	XPS:LI20:MC10	PB17 Elliptical mirror mover	M4	Positive limit switch/negative limit switch	Out position. Configuration is 'SetCurrentPositionAsHome',so need to drive all the way to positive limit switch to ensure driven out. In position. Drive all the way to negative end for IN position.
PB18 Focus Imaging Vertical	XPS:LI20:MC10	PB18 Focus Imaging Vertical	M5	0	Home at current position (0). Motor should not be touched or moved, should be clear in any case.

Safely retracting E320 assembly and setting up to clear e-beam/laser will be:
