3 years ago Yere can see the offset and that T0 is probably on the right. The only thing I don't understand is why it is necessary to set a separate offset when reading the start in G-code EEPROM from memory to offset. And flashprint also does not generate M612 line. (M612 X34.5 Y0.0 ; Set toolhead offsets) Then it's a mystery why Cura adds the T0 command before starting the G-code for two extruded printers. And as I read then the Printer refuses to continue.
Then I still have to test if the printer works without the M118 command.
I found a post on such a forum:
As you stated in a previous comment, command M118 is a proprietary thingy from FF with the following syntax: M118 {X Y Z} (max size of the printed area with object and e.g. a wall) {T0} {T1} {D1/D2} XYZ coordinates can be omitted afaik, T0 and T1 are left and right extruder respectively, so for a single-left print you'd only state T1 - and this is where the interesting part is - D1 (mirror) and D2 (duplication) are actually the key parameters to enable duplication/mirror mode. In these two modes, the print bed origin shifts to 66.5x125 (resulting in a print bed size of 133x250 mm). The bed is mirrored (happens through the printer firmware if D1 or D2 are asserted) with a keepout zone of x = 34 mm between those two mirror patches (so the two printheads won't collide). I talked with FlashForge about this and they confirmed this.**** https://www.thingiverse.com/thing:4574596/comments
Flashprint gives me this for duplicate mode on a simple box: M118 X16.60 Y16.60 Z11.55 T0 T1 D2
Flashprint gives me this for mirror mode on a simple box: M118 X16.60 Y16.60 Z11.55 T0 T1 D1

I found this .fff profile from Simplify3D. We can use it to create the cura profile
