Linear Compensation - Stratasys FORTUS 360mc Service Manual

Linear Compensation

Purpose
Linear compensation is a method of scaling the machine in both the X and Y-axis. XY tables
may incorporate some non-linear positioning which is introduced during the manufacturing
process. This can lead to a system building parts outside of the dimensional accuracy
specification. Systems build a Pulses Per Unit (PPU) part which is measured and used to
calibrate the system through operator input.
Operation
1.
A scaling part is built and cooled. Once cooled for a minimum of 30 minutes, it is
measured in the X and Y axis. These measurements are entered in the system to
compensate for any dimensional accuracy errors.
2.
The actual values are entered into the system and the system calculates the new PPU
values.
