Hi all.
Im New to cnc. Not been learning for very long. Hit a brick wall. Looked on youtube internet. With no joy how to solve the problem im drawing a simple arc. In autocad. Saving the file as dxf then im sending the file to lazy cam i clean it scale it generate the gcode. I then load code in mach 3 turn mode. and in the screen. It just shows circle. Ive tried it with a diamond shape with a radius Ive gone to general config and tried changing ij settings. To absulte and inc. etc. And same in lazy cam. And still same shows on screen. What am i doing wrong. Can anyone help.

LazyCam's turn module leaves much to be desired and can be problematic to use. That is one reason that LAZYTURN was created to be a replacement for that module. There is a manual for LazyCam which has a Turn tutorial in it ...... been over 10 years since that was written.
