try setting a position using G92
https://duet3d.dozuki.com/Wiki/Gcode#Section_G92_Set_Positionand then moving it. and add axis limit M208

Thanks for your reply,
I did a G92 U5, but that did not allow me to then perform a G1 U100 F1000 - do i need to do anything else?
I have not tried applying axis limits as I don't want the motor to be limited in any direction
Regards,

what the error?
-
No error, in the console the line goes green, but the motor does not move

@mark
i am afraid i have to insist on the m208see

I will try that later.
Maybe I am looking at this wrong and need to configure as an extra extruder as that does not have an endstop or axis limits. I wonder if I can setup a tool without any heater and run 2 tools at the same time

can you elaborate what that motor is doing?
-
Yes, it's simply feeding filament (down a ptfe tube to my hemera) in order to perform a load. There is a servo in order to disengage the filament from the motor once the load has completed. If I get this working then I can add another one for duel colour.
I am sure I am going to hit many road blocks and there might be easier/better ways but i want to try it anyway

a few weeks back there was a post about someone using 2 extruders for one filament.
i think it was done using the mixing ratio to drive 2 extruders at the same timehttp://blog.think3dprint3d.com/2016/12/using-diamond-hotend-with-duetwifi.html

@Veti very interesting, I will have a read.
Thanks

If you only want to use it as a loader but not during normal operation you could create it as an extruder and assign it to a tool to advance and retract the filament as needed and then reconfigure your tool as per normal printing when done.
