Changes to "Start" GCode for resin printer are ignored

Guest 9 Months+ 409

I've added commands to the gcode under "Start" for my LD-002H printer but they are ignored. Why? The goal was to drive the platform up and down a few times before printing, to remove bubbles between platoform and FEP. I made the Gcode visible (by editing CHITUBOX64 1.7.0\resource\machine\CREALITY_LD_002H.cfg: gcodeEditVisible:1) and changed the commands under "Start". These were the default commands of Chitubox:

G21;
G90;
M106 S0;
G28 Z0;

In words: Set units to mm; absolute coordinates; fan off; home z axis. I changed that to:

G21;
G90;
M106 S0;
G28 Z0;
G1 Z5 F25;
G28 Z0 F25;
G1 Z5 F25;
G28 Z0 F25;

However, the added movement commands (G1) were ingored. In fact, I can delete the entire list of commands under "Start" and the printer still behaves normally, as if it had these commands (it will still home). Is it not possible to issue commands by editing the GCode in Chitubox?
