I recently installed my dual extruder upgrade, and it's my understanding that I have to flash the firmware to use "M2E-Production-SnNRd-V101 - Dual." (If I don't have to do this to use the dual printer, then that solves my problems). After downloading this and opening it with the Arduino IDE (tested in 1.6.13 and 1.8.3), setting the board to "Arduino Mega ADE" (and then "Arduino Genuino/Mega or Mega 2560"). When trying to verify and upload the sketch to the board, I get the error: "using typefef-name 'fpos_t' after 'struct'). And this is on the Marlin.ino sketch.
Also I was trying to load filament in the second extruder in S3D, but couldn't find the jog controls for the second head. This is after changing the profile to the Makergear M2 Dual configuration.
The place to discuss your hardware and software/firmware modifications...

You do indeed have to flash the firmware with that version enable the second extruder and make it visible to the software.halolord01 wrote:(If I don't have to do this to use the dual printer, then that solves my problems)
To my knowledge, the only supported IDE version is still just 1.5.5. From the wiki page about firmware:halolord01 wrote: After downloading this and opening it with the Arduino IDE (tested in 1.6.13 and 1.8.3)
Version 1.5.5 is tested and recommended, 1.6.x is known to cause problems.
