I am brand new to this, and I just completed my 1st homemade CNC machine. I am demo-ing Mach 3 and Lazy Cam to run the machine. I like both programs, but after editing my auto cad picture in Lazy Cam and selecting "Post G-Code", the info box reads "Uploading G-Code" and then "Upload Complete." But, Mach 3 does not receive any info and when I open the LCam file with Mach 3, there is no G-Code in it. I'm not sure if this is just because I'm using the demo version or if it's because I don't have something working right. Help!!

The demo's are limited as to the number of lines which will be posted, 50 LC and 500 Mach, so that is what you may be experiencing. There are other limitations
on functionality in LC like offsetting etc.

Thank you, armed with your knowledge and other info I read last night I managed to correct my offset problem and load a couple small dxf. files after work today.

Glad you figured it out, have fun.
