Hi.
I have a small issue with my cnc 2030 which I bought lately, and Mach3
I design with Artcam express program, and when I load g-codes, the machine starts engraving mirrored the model I've designed.
If anybody knows how to fix it, please help.

Best regards.

Your axis is running backwards in Mach3. Go to Config > Homing/Limits, and check the Reverse box for the mirrored axis.

Thank you.
Need to check X and Y only, or Z too?

Only the one that's mirrored.

Thanks a lot. Problem solved 
One more question ..
When I load G codes and program start engraving, sometimes starts drill deep hole which is not programmed and breacks the bit.
Can you help me with that too?

Best regards.

Can't believe I had the same problem Thanks ger21
