It turns out this was two different issues The solution to the file not found was found on the duet forums, it turns out reprap and/or the duet board can't handle the ' " characters and others. Renaming the file with only (roman) letters and numbers solved the issue and got the file to load. Once that was done the code played out exactly like it did in the 3d preview (all wonked up). So, I took a look at the formatting of the first project .gcode file compared to mine and yeah. It was indeed caused by modal commands in the gcode. Manually (painstakingly) writing in the G0s and G1s on every line did get it to work. I have taken to use ESTL V12 CAM which has a convenient option for this requirement that doesn't require writing a bit of custom compiler for either software and still keeps within my budget. That was an unexpected goose chase but it got fixed in the end and all work's well now.
