Firmware Retraction for V5

If you are using v5 you have to change your post processing script from for example:
{REPLACE "G1 E-0.5000 F1800\n" "G10\n"}
{REPLACE "G1 E0.0000 F1800\n" "G11\n"} in v4 to

{REPLACE "G1 E-0.5000 F1800\n" "G10\n"}
{REPLACE "G1 E0.5000 F1800\n" "G11\n"} in v5. This is because v5 uses the positive number to indicate recovery instead of 0

Which now that I think about it might be a bug for non-firmware retractions

Nice post! Just to mention it, the commands above require that you are using a 0.5mm retract distance with 1800 mm/min retract speed. So if you use different values, be sure to update the values accordingly.

It looks okay to me. There is a G92 E0 right before the positive G1 E+ command, so that should correctly advance the filament for the prime.
