@dc42 I wonder if you have any further suggestions on this issue? I'm really keen to work with you to get it sorted, but without anybody seeming able to identify anything obvious in the macro, no error messages to indicate any problem on the Duet, but with a total failure of movement and a rather core function needed for every CNC toolpath I'm unsure where to go next..? Should I just write-off this approach and go with a G38 based route like @Yveske, or are there more things I can try to help you diagnose the issue?
I was really hoping to move onto replacement Vue modules so that Ooznest customers (and others) can make use of the latest firmware 3.xx improvements (which I need for consistent laser support) and the excellent DWC-CNC work of @Sindarius (to hopefully provide a longer-term maintainable RRF3 compatible UI) - but at the moment I'm dead in the water. I obviously cannot expect customers to update their installations if I can't reproduce the existing capabilities they currently have under RRF2 & Ryan's original DWC.
Many thanks in advance. E
