@obeliks Doesn't seem like that code stops the print. Seems to be the M907 which causes the print to stop.

1_1535921567935_Test Single Nozzle Enabled.gcode 0_1535921567934_Test Single Nozzle Disabled.gcode

Here is the gcode generated. The file "Test Single Nozzle Enabled" has the Single Extruder Multi Material option enabled in Printer settings in Slicer PE. If you search through the gcode, you can see it has M900 and M907 commands in it. Both commands give errors and will cause the printer to stop.

The other file has that option disabled but it only contains M900 command but it will give me an error and still print.

@phaedrux I have it set to RepRap/Sprinter

Running into issues trying to get dual extrusion to work on the Duet with the Slic3r Prusa Edition. Here is the error I am getting when I try to print using gcode sliced from the slicer.

8:47:54 PMError: M900 command is not supported
Error: M907 command is not supported

This is the error I'm getting when I try to use Silc3r Prusa Edition. It will print with two extruders into a cyclops when Single Extruder Multi Material is disabled, but once it is enabled it stops after purging and gives me that error.
The printer itself works with other slicers like S3D and Cura, but it's only when trying to run gcode from Slic3r PE with Single Extruder Multie Material enabled do I get the error messages and it stops.

Anyone got a solution to this?

Thank you
