Sculpfun S9 loses focus/power when cutting on left side of the MDF board

My Sculpfun S9 seems to lose focus/power when cutting on the left side of the MDF board.
Cuts made on the right side of the mdf board are perfect, while those made on the left side of the board cannot cut the board, using the same parameters.
Has anyone had this problem?

Make sure the board is level. Either the board is warped or your surface that the board is on is not square to your laser head.

The board level is ok and the problem continues

Let me re-interate what @HalfNormal stated… the only way this could happen is if the laser head is at a different distance from the material when the anomaly occurs.

You should be able to hang it on a wall and work, so level is handy but it’s hard to determine if the head is same exact distance …


It has to be square in all three dimensions, which is difficult to measure…

If you can take accurate measurements of the head to material distance in multiple locations.


I you have a spacer block, you can use it, just manually move it over there…


Can’t really think of anything else that could cause this other than a cable issue, which is highly unlikely but I’ve seen it… usually the wire just breaks.

Good luck
