How to Invert Motor's Direction
If your machine engraved a mirror or inverted image. If you click left on the computer software, the machine go right.
Your machine's axis direction is wrong. This is a easy problem.
First
Let's find out which axis is in the opposite direction.
Move the axis by software, for example Engraver Master.
If you click right (X+), the machine goes left. That's the X axis.
If you click up (Z+), the machine goes down. That's the Z axis.
If you click back (y+), the machine goes front. That's the Y axis.
Now
Open the Device Settings page on the Engraver Master. You can easy solve the problem by enable or disable the Reverse N Axis options.
On Bachin Master software, it is a similar operation.
