I am a gcode programmer for a long time. I am working on doing side work to play with my other hobbies. I got a call from a guy that is looking for a programmer to help him out. He bought a router from China that is using mach3 to control the machine and it has lazycam to program it. He has an older machine that he has no issues with. I know from searching the web that the software uses a "DXF" file to basically copy the picture? He is telling me that when he programs a part it is spitting out strange code and his program is not working? I will go to his shop after work to strat figuring out his issue. He said the he thinks the machine is supposed to be turn key? I don't trut or like anything from China due to issues we have here with their quality. Can someone give me some pointers on this configuration and what to look for other that code output? Is there post psocessor?
