Hi! I'm new to lasers and just got an FB3QS to use with a generic 2w rgb ilda laser. I'm having a problem with stabilization of one of the axis of the galvanometer scanner.
When the laser is in "auto" mode the problem doesn't occurs. But when I put the laser in ilda mode with the FB3QS one of the scanners axis starts to vibrate.
I've done two tests:
1- I've made Quickshow draw a horizontal line. The line is stable and straight, but both ends of the line drifts to the sides. Touching the bottom mirror of the scanner I can feel this axis moving to draw the line. Touching the upper mirror of the scanner I can feel the mirror is completly immobile, with no vibration.

2- I've made Quickshow draw a vertical line. The line is not stable, it oscilates do the sides.Touching the bottom mirror of the scanner I can feel this axis has a little vibration (but it must be completly immobile, I guess). Touching the upper mirror of the scanner I can feel this axis moving to draw the line.

The conclusion I got is that there is some kind of interference in the bottom galvanometer scanner, when it needs to be completly immobile on test 2, this mirror is vibrating and causing the vertical line to oscilate.
I tried to mess up with the trimpots of the scanner board on ISC, SCA, LFD, HFD, PSC and LIN but with no luck.
The most strange thing is that this problem does not occur in "auto" mode (when the laser uses a mic to move and internal memory of drawings)
Sorry for my english as I'm from Brazil.
Can somebody help me with this problem?
Thanks!
