Offset Calibrations

Adjusting Z Calibration and XY Tip Offset

Z calibration is needed to adjust the slight differences in tip heights. XY Tip
Offset is required to correct for the slight differences in tip alignment. Failure
to perform these calibrations will result in poor part quality and possible
LOE's.
Z and Tip Offset calibrations are mandatory whenever the tips are
replaced. If Tip Replacement is chosen from the Interface Panel
Maintenance>Machine>Tip>Replace, you will be prompted to perform the
calibrations as a part of the replacement procedure.
These calibrations can also be run without performing a Tip Replacement.
From Idle, choose Maintenance>Machine>Tip then Calibrate Z or Calibrate
XY.

Z Calibration

1. Press Maintenance.
2. Press Machine.
3. Press Tip.
4. Press Calibrate Z.
5. Press Start Part. The printer will automatically build a Z Calibration part
6. Repeat steps 1-5 to verify proper calibration.

(one square of model and one of support). The system will then measure
and calibrate the Z Axis for tip depth and tip level. (Build time is approx-
imately 5 minutes).
NOTE: Unusual circumstances may require that the Z calibration
values be entered manually. To change these values, see
