GSK 980TB3 soft limit issues

Hiya folks,

Recently purchased a LCK6132 lathe running a GSK 908tb3 controller. I've run into a small issue where the X axis kept coming up with an overtravel alarm in either + or - direction, essentially the axis was locked in place. Conteacted the manufacterer and they sent through info on how to reset the soft limits to factory but we can't seem to figure out how to set the limits back to what they should be; the manual is fairly obtuse and the manufacturer has gone dark. Does anyone have any idea on how to fix?

Also, if anyone has any info on a post processer (Fusion 360) for this control, I'd be grateful

Cheers
