So, I exported GCode from QCADCAM which I'm learning. I reordered it and see that when I run it, one box won't engrave properly no matter what I do. In the origional code, it works. I've attached both copies of the GCode, (GOL1_Test is the QCAD output and GOL_TEST4 is my revised copy) I've included a screenshot from Mach 3 showing that the Box for 4 won't engrave properly and the code from the QCAD output commented out. I am completely at a loss as to what I might have missed. Any help would be greatly appreciated. Thanks.
