I mean instead of z moves down in M3 inserted and instead of z moves up M5 is inserted.
Hello, You can edit the gcode-file, and replace all "Z-" with "M3;" and then all "Z" with "M5;" It works for me with repetier. Why ";" in the replacement??? Simply, the rest of the line is a comment. So from "Z-0.100" will be "M3;0.100" Hope it helps. Greetings
Very important: at first "Z-"s and then "Z"s, otherwise you have only "M5"s.
Thanks!!!!!!!! There is no switch in FlatCAM for that?
No, no switch in FlatCAM, unfortunately. I will keep it in mind for future releases though. JP
