Mirror imaging

[cropwell]

This year I decided to abandon my ideas to convert my Chinese desktop mill to CNC and have spent out on an A4 gantry mill and a license for Mach3.
I have most things set up OK and have made a penholder to go in the spindle mount. The file that I created with Corel part loads into LazyCam (it misses out circles) and I can greate G-code which will draw out the Corel original drawing to size (those bits it imports to LC) Now here's the problem - it is a mirror image (X-axis). If I rotate the drawing 90degrees in LC it mirrors on the Y-axis when I 'print' it..
The drawing appears correctly oriented on the Mach3 table display.

My thoughts are that I have Mach3 set up for a traditional moving table machine, but I have read through the Mach3 manuals and can find no reference to 'mirror imaging' or any term that might mean it.

Am I doing something stupid ? Is it a newbie goof ? It is doing my head in.

Cheers,
Rob

Hi,

Is this happening for all gcode or just converted data?

Sounds like one axis may be going the wrong direction, not sure what zero and axis directions are in Corel, but I'm guessing that one axis definition is different to your machine, hence the reflected mirror image.

It was indeed a reversed Y axis, which was sorted out by reconfiguring Mach3. My frustration was with the Mach3 manual, which is not well indexed. The answers are there, just not accessible.
