textLines = text.replace('\r', '\n').replace('\n\n', '\n').split('\n')

Essentially replacing CR with LF, replacing any double LF then splitting lines on LF.

Not dangereous at all the G91 put it into relative mode and so the G1 Z7 is a relative move of +7.

How can you be sure that You can go down to 7mm with your Z....
You might crash your extruder and x axis into the print...

I would remove the Z code and let the head move to some Parkposition only and turn off heater...

Suggestion:

G1 X0 Y130 F1000
