Test for a two-color impression with ender 3, just added gcode. The gcode is used to pause the printer at the desired height and clear the head. Then you have to press once to activate the preheating to change the filament and press again on the printer's wheel to continue printing. Here are the gcode I've added: Filament Change to Insert at Layer (Line or Height of Piece) Desired Explanation: M83; Switch to Relative E Values for Any Needed Retraction G1 F300 Z3.24; Raise Head Up by 1 mm G1 F9000 X20 Y200; Move Head to Desired Location G1 F300 Z50; Raise Head Up by 50 mm M104 S0; Stop Extruder at 0° M0 Click To Restart; Stop and Press to Send Next Section M109 S210; Activate Extruder at Desired Temperature (Change Filament) M0 Click To Restart; Stop and Press to Continue G1 F300 Z3.24; Lower Head Back Down to 1 mm Above Piece G1 F300 Z2.24; Lower Head to Desired Height G1 F9000 M82 Functional Origin: M83; Switch to Relative E Values for Any Needed Retraction G1 F300 Z1.8; Move Up a Millimeter to Get Out of the Way G1 F9000 X20 Y200 G1 F300 Z50; Too Close to Bed--Move to At Least 50 mm M104 S0; Standby Temperature M0 Click To Restart M109 S210; Resume Temperature M0 Click To Restart G1 F300 Z1.8 G1 F300 Z0.8; Move Back Down to Desired Height G1 F9000 M82; Switch Back to Absolute E Values
