I haven’t used the machine for some time now but when I went to use it I’m getting vertical banding on acrylic, seemingly only when engraving horizontally. I’ve made 1" square and engraved it at 0 deg in Lightburn and I end up with vertical bands. The banding appears wider & further apart if I increase the speed from 100 mm to 200 mm. With only changing the direction of the scan to 90 deg in Lightburn the bands are not there leaving all other settings the same.
I’ve cleaned & aligned the mirrors and adjusted belt tension on the X axis. I’m looking for a direction for other potential places to look. Thanks in advance.
