Hello, I have a Full Spectrum 90 Watt Pro16X24 Laser Machine. I just started having an issue yesterday where it started jumping around on the Y axis. Even when just homing the laser head it wants to continue past where the further most area is and grinds. During a job it may cut fine for awhile but then just totally may skip about an inch or so up on the Y axis. Does anyone have any ideas? Thanks so much in advance.
