# Temporary transition to the machine axis coordinate system (#MCS)

Select: #MCS ON [ EX TOOL ]

With #MCS ON, active transformations and all offsets calculated in the axes can be temporarily deactivated so that machine axes can be directly positioned.

After leaving the MCS, the state before selection is restored.

Effectiveness

- Active until deselected or up to program end.
- With the ‘EX TOOL’ option, no tool offsets are included in the MCS calculation when the tool is changed so that machine axes can continue to be positioned directly. Only with #MCS OFF are tool offsets again included in the calculations.
- Default offsets (e.g. zero offsets) can be programmed in the MCS. However, they are only active until they are deselected and are not saved.
- It is not possible to select CS, ACS, ECS and TLC in the MCS.
