Hi all,

I am in serious need of help trying to use the 4th Axis on my Chinese 3040 CNC.

When I bought this unit from Ebay, it came with a 4th axis attachment with a Self Centering Lather chuck attached. The connector is a 4 pin Round that screws to the main unit box.

I have attempted to use the attachment to no avail. The Instructions manual that came with the unit says to simply open the GCode file and replace 'X' with 'A', save and run.

This does not work.

I am using Mach3 as the GCode controller and Aspire as the design software.

My goal is to be able to engrave names and/or logos onto Pen barrels using the 4th Axis.

Thanks in Advance.
