Hi, I noticed that the G-Code generated for drilling has the same speed for xy and z movements. For optimization it would be best the specify two different speeds for xy and z. More over it would be even better if for the z movements could be possible to specify different z speeds when actually drilling and when moving close/away from the drilling surface. (Similar speed optimizations could be implemented for the other G-Code files. Use different speeds when actually routing and when moving between two points but not engraving the PCB)

For drilling, XY movement are at maximum speed (G00), while Z movements are at feedrate speed (G01), which can be specified in FlatCAM. Could you post part of a G-Code file generated with FlatCAM which moves in XY at feedrate? Thanks, JP
