Lathe Macro execution was created by JuFu

Hello, I did CNC (retrofit) an old Magdeburg D30 lathe.
Started wit AXIS, but changing to gmoccapy now.
Included Lathe Macro and it seems to work (so far).
here my question: when I parameterized a Lathe Macro, how do I get it executed (the lathe to move as wished)?

Not sure if this is what you mean but have you tried clicking on the 'Play' button:

Thanks for the fast response.
Will check for that button. Was not aware of it.

If you have a low resolution screen, the play button will be hidden.
There should be a topic or two here about how to fix that.
Sorry, but on the phone.

Is there any chance to see/read the nc-code generated by Lathe Macro?

It doesn't generate gcode. It calls the respective ngc subroutine and passes the required parameters.
eg 'turning.ngc':

Code:

;Turning

O<turning> sub

G8 ; Radius mode (easier maths)
G18 ; XZ Plane
G21 ; Metric Units
G90 ; Absolute Distance
G91.1 ; but not for arcs

M6 T#8 G43

#1 = [#1 / 2] ; because of radius mode
#14 = [#<_x>] (starting X)
#13 = #<_z> (starting Z)

#20 = [#6 * SIN[#7]]
#21 = [#6 * COS[#7]]
#22 = [#6 / COS[#7]]
#23 = [#5 + #6 - #20]
#24 = [[#13 - #23] * TAN[#7]]

G96 D2500 S#2 ; Constant Surface Speed Mode
m3 ;Start Spindle
g95 F#4 ; Feed-Per-Rev Mode

O90 IF [#9 GT 0.5]
	M8
O90 ENDIF
g4p1 ; Wait to reach speed

	O100 WHILE [#14 GT [#1 + #3 / 2]]
        g0 X #14
	#14=[#14-#3 / 2]
	G1 X #14
	G1 Z #23 X[#14 + #24]
        O101 IF [#6 GT 0]
                G2 Z#5 X[#14 + #24 + #21] I#21 K#20
		G1 X[#14 + #24 + #21 + #3/2]
        O101 ELSE
	        G1 X[#14 + #24 + [#3 * .6]]
        O101 ENDIF
	O104 IF  [#7 LT 0]
		G0 X#14
	O104 ENDIF
	G0 Z[#13]
	O100 ENDWHILE

	G0 x#1
	G1 Z #23 X[#1 + #24]
        O102 IF [#6 GT 0]
                G2 Z#5 X[#1 + #24 + #21] I#21 K#20
		G1 X[#1 + #24 + #21 + #3]
        O102 ELSE
	        G1 X[#1 + #24 + #3]
        O102 ENDIF
	O106 IF  [#7 LT 0]

Is this the original gmoccapy screen?

Not sure what you mean exactly but the 'Cycles' tab is usually not part of gmoccapy. It is generated by loading the external lathe macro addon.
