Front Panel Functions 4-3
If a pattern is active then the new Origin position is effective only until the end of the
pattern. When the EP ("End Pattern") command is executed, the old location of the Origin
is reinstated. See the BP and EP commands in Chapter 3.
During Z Arrows mode (see "Z Axis Arrows", below) the SET ORIGIN button has no effect,
since the Z axis origin always remains at the Z Home position.
GO TO ORIGIN
The machine performs a vector to the Origin position, as though an MA 0,0; command had
been received. The motors are left at full power. The Position Change status bit is set.
If a pattern is active the carriage moves to the pattern Origin rather than the "main" Origin.
(See the BP command in Chapter 3.)
If personality parameter 48 is set properly the vector to the Origin is preceded by a Find Z
Home operation, and is followed by a Z move to the original Z location. This can help
prevent mechanical interference during the vector.
You can use this button to find out where the Origin position is, or simply to move the
carriage to the Origin for any reason.
The Digital Outputs are unaffected by this vector, regardless of the MD and VM commands.
An antibacklash vector is performed if it is enabled by the AB command and not disabled by
the VM command. The acceleration and step rate are as established by the AC and SR
commands. No mid-move Digital Inputs Response is active; see MN.
If the Arrow Buttons are in Z mode (see "Z AXIS", below) then GO TO ORIGIN causes the
Z motor to move directly to the Z Home position. X and Y are not affected. Note that the Z
origin always remains at the Z Home position, so the SET ORIGIN button does not affect
the Z axis. Also note that it is possible for the Z axis to be "below" its Home position; in this
case GO TO ORIGIN will move in the negative direction to the next position where Z is
zero. Caution: this could be a long way if the Z axis modulus is large; see the CZ command.
The GO TO ORIGIN button is ignored while the machine is in the Emergency Stopped state,
but works normally during the Paused state. It is also ignored (in XY mode) if the XY
Origin position is outside the travel limits. (See the TL command.)
TEACH
The machine saves the current XY position as a Taught Point and sets the Taught Point
Available status bit. If the host has previously sent an OT ("Output Taught Point")
command, the taught point coordinates are immediately sent to the host and the Taught Point
Available status bit is cleared.
If the Taught Point Available status bit was already True, the TEACH button has no effect;
thus, each taught point must be "used" (via OT or MT) before the TEACH button can be
pressed again.
