Can I use relative pos by +/-?
-
If I in start code want some relative movement (XYZE)
- Can I write G1 XYZE+(randomnumber) rather than doing G91 and G90 in every other line?
so:
G1 XYZE random lines....
Then
G1 E+5 to extrude 5 more mm
instead of
G91
G1 E5

@pro3d G91 will set relative positioning and all G1 commands after that will be executed as relative moves until a G90 command changes the positioning to absolute. Thereafter, all G1 moves will be executed as absolute positioning until a G91 command changes it back to relative. Be aware that to switch the extruder between relative and absolute, you need to use M83 and M82. Does that answer your question?

My badly stated question was if I could just use [XYZE]+[nr] instead of switching back and forth between relative and absolute just by using the +/- sign in the command line

@pro3d Ahh, I see. AFAIK that's not possible.

No you can't. Commands such as G1 X-10 already have a defined meaning, i.e. move to X coordinate -10. Similarly, G1 X+10 means the same as G1 X10.
