X & Y Axis travel is wrong way

General

Hi All

I have built a plasma table running on Centroid Acorn.

The machine homes to top left of the table so when Sheetcam creates the code the movements are the wrong way I want it to travel in the positive direction.

Can something be changed within Sheetcam or is it a case of reversing the motors in the Acorn software?

I have looked in Sheetcam but cannot find anything that looks like it would help.

Thanks in advance

The table homing corner is not relevant to sheetcam, that is a condition you setup in your controller via configuration settings of the controller.

Sheetcam calculates a toolpath relative to the origin (X0,Y0,Z0) of a Work Coordinate System (WCS). You define the origin in menu Options-‘Job options’.
You set the WCS (such as G54) in your pp or use the controller default WCS.

This is a good gcode reference that may help you.
