Hello, I have Sculpfun S9 laser. The laser has started not producing straight lines lately, what can I do?
This looks like gantry bounce. Did you move the laser to a more compliant workbench, pedestal or stand?
The other common culprit is the engraver head itself. With the power off, grip the head of the engraver (or laser module) down low and try to wiggle the bottom of the module in the Y-Direction. The X-Axis ‘carriage’ has rollers that are adjustable and take up the slack. These adjustable rollers can become loose over time. The symptom of this is wiggling in the Y-Axis when stopping or starting an X-Axis move.
The mechanics of the S9 need to be carefully tuned. Out of the box, it isn’t. Check the guide here:
