Z-Axis Over Travel at Cycle End
This error will occur when the Z axis load offset is too large. The machine is effectively trying to move Z
beyond the axis limits. The machine will not physically move the axis but will fault before moving the
axis based on the calculations it is performing. To clear the fault, press ok to acknowledge the message,
press
RESET
, wait for the red screen to change to blue, and turn
SERVOS
on. You will need to change the
Z axis load offset to the correct maximum value. First, scroll down the code in the auto screen (which
should still be up) until the line with the command [G54] is in view, and note the Z value underneath.
Press
MANUAL MODE
; the machine will still be in [G54]. Press Z+ until the Z axis stops in its bottom
most position. Note this second Z value. Subtract the original value from the second value, giving you
the maximum Z value for the load offset. This value will vary based on the individual tool set, because it
is based partially on tool geometry (tool length, reception height etc.). To set the new Z axis load offset
tap [Settings], enter the new value into the field labeled [Z Axis Load Offset] and tap save at the bottom
of the screen.

Recovering from Error Messages
A slurry flow fault, low air pressure, unreferenced axes or Z Axis over travel may cause error messages to
appear on the user interface. To clear these messages and re-gain your control of the machine, the
RESET
button must be pressed after action to correct the error has been taken, to clear messages.
Contact OptiPro Service if additional support is needed.
For example: If you see a low air pressure error message, it may be because your air compressor was
shut off at some point causing the machine to fault out. If your compressor has already been turned
back on, the only step needed to clear the error is to hit the
RESET
button. If the software has been
closed, the axes are no longer referenced. This will cause an error message to appear. Press the
RESET
button, turn the
SERVOS
on, then
ZERO
and then
CYCLE START
. This will reference the axes and your
machine will be ready for production.
