#2 Check the Engraving Mode in XCS

Note: The current V1.2 version of XCS software has fixed the issue. Please make sure your XCS version is up to date. If you are still using an older version, please follow the instructions below.

For bitmap processing, there are two types of engraving modes. The Bi-directional mode may cause a backlash when the laser module moves.

Uni-directional: the laser only fires when the module moves from left to right. It then goes back to the left to start a new line.
Bi-directional: the laser fires when the module moves from left to right and immediately starts a new line from right to left.

Please follow the steps below to troubleshoot:

If you are processing a bitmap image, check if the engraving mode is Bi-directional.
Change the mode to Uni-directional and see if that solves the issue.
