G18 test / check

Postby Robertspark » Mon Oct 30, 2017 2:49 pm

I have never used G18 before, but could someone who knows how it is suppose to work (and used it before + regularly) please test it, thanks.

I am looking at using G18 for lathe or turning XZ axis.

Problem is if I change to G18, and load a gcode file containing only X+Y motion, it appears in the viewscreen where Y motion now becomes with Z axis motion?

Is this they way it should work?

Maybe I am better leaving it as G17 and just changing the toolpath view for XZ view

{problem is I notice that others lathe macros seem to change the workplane to G18 and only X+Z motion appears in the macros so don't know if there is a problem and where it is}

..... think I've figured it out....

:oops: :oops: I've been a bit of an idiot ..... {only work in XY plane normally}

.... G02 + G03 motion.... answer in UCCNC manual.... :D

Try changing your "J"s to "K"s. ANd "Y"s to "Z"s.

I = X coordinate
J = Y coordinate
K = Z coordinate.

Notice that UCCNC is not recognizing your J while in G18 mode.

Edit: I was a little too slow.

Yes, that's correct, arcs on the G18 XZ plane require I,K center point coordinates.
