This was one of the first things I did with my machine! Can you post a little of the G-code in your post? I suspect the answer lies in there somewhere. Or maybe you have 'Z inhibit' turned on in Mach3? This is in the bottom LH corner near the reset button. You would still be able to jog manually if this was enabled, but it would ignore any G-Code settings. When you use the Wizard, you set the home position for Z, the top of the text, and bottom of the text. With a pen, the top and bottom of the text are the same since it has no depth as such. |
