Raise3d with Cura - Extruder Count

[mrmdsims 0]

I am trying to use Cura 5.2.1 to slice for my Raise 3D N2 - single extruder.  The printer is setup properly in Cura as a single extruder.  When I try to load the gcode on the Raise printer,  I get the following error on the printer:  The printer only has a single extruder and cannot print dual extrusion gcode file.

 

Any suggestions on how I can fix this error?

 

Below is the printer start GCode

G90

G21

; home all axes

G28

G92 X0 Y0 Z0

; move heatbed into position

G1 X20.0 Y20.0 Z1.0 F1000

I think it might be tripping up on the T0 command, which is really weird. For context; the T command is how the printer is told what extruder to use. So even if your printer only has one extruder, telling it to use the first one (T0) should be a valid command)

Alternatively, it might also be the G92 E0 E1 command. You could try and see what happens if you change that to G92 E0

Thank you.  I will try both options.  Could I remove the T0?

You could try. I don't have any experience with the raise3d printer.

I use the Raise3D slicer occasionally for comparisons with Cura.

With an N2 installed in IdeaMaker there are T0 commands in the startup so they are probably alright.  My guess would be that the firmware is similar across their product line.

That G92 E0 E1 command looks to be contradictory and so it's probably illegal.  It's trying to set the extruder location to 0 and to 1 at the same time.  Not good.

This is the N2 StartUp Gcode from Ideamaker:

M221 T0 S94.00  ;set the flow to 94%

G21 ;metric
M140 S60.00 ;Bed temperature
M104 T0 S215.00 ;hot end temperature
M109 T0 S215.00 ;wait for hot end
T0 ;set the tool
M190 S60.00 ;wait for the bed temp
G21 ;metric units
G90 ;absolute movement
M82 ;absolute extrusion
M107 ;fan off
G28 X0 Y0 ;Home the X and Y if they need it
G28 Z0 ;Home the Z if it needs it
G1 Z15.0 F300 ;move the nozzle up
G92 E0 ;reset the extruder
G1 F140 E29 ;purge
G1 X20 Y0 F140 E30 ;move while purging some more
G92 E0 ;reset the extruder
G1 F9000.0 ;set the feedrate
M117 Printing...
M1001 ;enables the power resume function.  There should me an M1002 in the Ending Gcode.

 

I made up the one below.  First use the "File | Save Project" command to save your current StartUp Gcode.  (If you were to open that new 3mf file in Cura it would bring in your original StartUp Gcode.)

After backing up your current startup gcode in the 3mf project file, you can try this by copying and over-writing the current StartUp in the StartUp Gcode box in the Cura Machine Settings dialog.
