(Ripped from my post to the GRZ forum months ago, no help)
Hello,
(MC5, build21. Windows 7, 64-bit)
I mostly use MC (a LOT) for lithophanes and 2.5d carvings, and MC5 certainly seems faster when it comes to linking toolpaths than MC4. I have found, intermittently, that MC5 will create toolpaths that appear to be UNDER the actual picture (all the green lines that show the finish path are underneath). When the gcode is written, it has no Z movement, it just rasters across the piece at some depth. What is odd to me is that I can't seem to predict when this will happen. I have successfully made 4 or 5 toolpaths using MC5, but have had this issue at least 3 times now.
Just to make sure I'm not high, I used the exact same picture with the exact same settings (I think) to create a toolpath with MC4. It works just fine.
I'm guessing there is some setting that I'm missing, but I'm not seeing it. I was going to attach the STL, but it's huge. I did attach some screenshots and the two gcode output files though.
If someone could set me straight, that would be great.
Thanks,
Chris
