Return to Object Z Height in "After Side Transitioning" Section

I’m trying to do a side transition at a particular XYZ coordinate on an MK3. I’m able to move the head to that location and purge the filament properly. I currently move the print head to Z50mm at position X235 Y15. This makes a nice little rope coil of filament on the bed. I then want a condition that will raise the print head if the currently printed object is above 50mm so I can move the bed without hitting the object. I am using the “nextZ” variable in the after transition section, but its value resolves to 50mm (current position), not the next Z position for the object. The documentation states that “nextZ” should be the “Next Z position (on the print) “ (Section 4.7)

Here is my code:

Before transition:

@printerscript 1.0

"G92 E0 ;Reset extruder"

"G1 X235 Y15 F3600 ;Move to blob location"

"G1 Z50 ;Raise printhead to 50mm"

"M107 ;Turn the fan off"

After transition:

@printerscript 1.0

"G92 E0 ;Reset extruder"

"M106 S255 ;Turn fan on"

" ; nextZ = {{nextZ}}"

if (nextZ>50) {"G1 Z{{nextZ}} F2000"}

"G4 S15 ;wait 15 seconds"

"G1 E-1 F1200 ;Retract"

"G1 Y210 F8000 ;Break filament"

"G4 S5 ;wait 5 seconds"

"G92 E0 ;reset extruder"

Any help appreciated.
