Hello everyone,   im fairly new to the world of lasers….  I've had my D1 Pro 20w for about 8 months.

with that being said,  all of my cuts were as straight as an arrow…. all of the sudden its cutting wavy/curvy

lines on a straight path???  it could be the wood is a little warped (got a bad batch of birch from amazon??

or it might have something to do with the z-axis extended riser that  I am using??

D1 Pro 20w  1/8 birch plywood…..   cut 100%  spd 6 (I tried 5-7 spd) no difference…

and I have cut warped wood before and it still cut straight?

any suggestions will be greatly appreciated and taken into consideration..    Thanks, charlie
