I’m looking for help with the following. I need to add a block at the end of a line if it does not already exist. The line could be in any of the following formats (M could be either 3 or 4, S could be and number):
M4S10000
S10000M4
M4 S10000
S10000 M4
I want to add the string “G4 P1” to the end of the line as long as it doesn’t already exist
M4S10000 – Append to become M4S10000 G4 P1
M4S10000 G4 P1 – Ignore the line and move on
Original line left out a few conditions:
gcode = gcode.replace(/(S[0-9]* M[3-4])|(M[3-4] S[0-9]*)/g, ‘$& G4 P1’);
I’m looking to expand it to cover with or without a space between S and M blocks
gcode = gcode.replace(/(S[0-9]* M[3-4])|(M[3-4] S[0-9])|
(M[3-4]S[0-9]|S[0-9]*M[3-4])/g, ‘$& G4 P1’);
Next I would like to do is make sure we don’t add “G4 P1” if it’s already there
