Marlin Deluxe Firmware with Autoleveling, Ditto Printing and more....

This is my Marlin mashup using the latest release and adding some additional features. This version is tuned to the gMax 1.5XT but should work with any RepRap style printer. Dual X-Carriage support has been stripped out completely.(who uses that anyway?) and replaced with Ditto Printing capabilities. When Ditto Printing is enabled Extruder2 will mirror Extruder1 so you can print two of the same objects at the same time using both hotends simultaneously. This is a feature in Makerbot's Sailfish firmware and Repetier but not Marlin. If you have a dual extruder you can enable/disable ditto printing via the M420 S1 (enable) or S0 (disable). If you have an LCD screen, you can enable/disable ditto under the "Prepare" menu. The size of your ditto printed objects are limited to the distance between the two nozzles. But if you need to print a lot of the same objects and the parts are less than the nozzle offset, Ditto Printing will cut your printing time in HALF!

Main features

• Auto bed Leveling & Z probing
• Ditto Printing
• Full support for M600 (filament change) - When invoked, tool head moves to predefined location, extracts 100% of the filament from the hot end and sounds an alarm via the LCD screen. The print resumes after the LCD knob is pressed.
• Full support for 'Out of Filament Sensor'- will trigger an M600 when filament runs out and sensor is triggered.
• Servo Support
• Arc Support
• Look Ahead
• Thermal Runaway Protection
• Camera Trigger
• And all other features of the 2015 Marlin release.

This was tuned for a gMax1.5 XT dual extruder printer but it should run on any single or dual rep rap style printer with a few tweaks.

The original post for this release with detailed information (and also firmware) can be found on the gMax users forum at the URL below:

While the target audience for this firmware is gMax users & printers, I am creating this repo with the hopes others will use it and adapt it to their RepRaps to further enhance their 3D printing experiences.

Enjoy! - Shaqfoo
