badprinter2 second extruder offset

Hi all,
i'm new with S3D and I didn't find a solution to my problem, in posts o tutorials...
The point is: does any one of you tried the dual extrusion print using Bad Printer 2 (a marlin modified firmware)?

while I've setted the offset for T1 in the Gcode Tab and the preview works fine, in the printing process the offset is completely ignored and the two part (processes configured following tutorials) are printed in two differet positions not mixed as it should be.

Not found other place where to set this parameter.

may anyoune tell me how to fix this behaviour?
Thanks a lot

Re: badprinter2 second extruder offset

You need to set the offsets in the firmware as well. I believe with marlin you can use the M218 command.

For example, to set the T1 offset to be 32mm in the X-direction, you could use
M218 T0 X32.0

Thank You CompoundCarl for your reply. One more stupid question, where can I find the firmware configuration file? or exactly where should I put the code?
I'm starting to use the program and I'm not very familiar with this files, indeed.

Thanks

You can add that M218 file into your starting script (in S3D, click Edit Process Settings, then select the Scripts tab)

Re: badprinter2 second extruder offset

After i did some tests, i used succesfully the script tab in the Process Settings.
I add the instruction M218 T1 X26.0 in the gcode so the second extruder worked properly, except for a 0.5 mm misalignment between the part printed with first extruder and the part printed with the second one. Must check the reason, but I obtained the wright overlap of the two parts of the model.

Thank You all for your answers
