I am adding a second extruder to my i3 variant ( Marlin on Mega and Ramps )
Before I wire in the extruder thermo, stepper and heater, I am wanting to test movement.
If I run the following gCode, the last line, which I would expect to move the second extruder nozzle ( T1 ) to X90 Y90 does not, but instead still moves T0 to that position.
Why ?
M107 ; fan off
G21 ; set units to millimeters
G90 ; use absolute coordinates
M92 X160 Y160 Z4000 E80 ; set steps per mm for standard belt config
M204 S2000 P2000 T3000 R3000 ; set default accelerations
M201 X2000 Y2000 Z100 E2000 ; set max acceleration for X and Y
M205 X20 E25 ; set max jerk
M203 Z2 ; -- Set maximum feedrate
M218 T0 X0 Y0
M218 T1 X67 Y10
G28 XY ; -- home X and Y
M203 Z1.2 ; -- Set maximum feedrate for Z axis
G28 Z ; -- home Z slowly
M203 Z3.3 ; -- Set maximum feedrate for Z axis
G0 Z5 ; lift the Z axis 5mm
G0 Y125.000 F4000 ; reposition Y to bed centre
G0 X125.000 F4000 ; reposition X to bed centre
G4 S2 ; wait 2 seconds
T0 ; specify tool 0 - nozzle 1
G0 Y110 X110 F4000
G4 S5 ; wait 5 seconds
G0 Y100 X100 F4000
G4 S5 ; wait 5 seconds
T1 ; specify tool 1 - nozzle 2
G0 Y90 X90 F4000
