Adding a independent Motor

mark

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?

mark

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

i am afraid i have to insist on the m208

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

Veti

can you elaborate what that motor is doing?

mark

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 time

@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.
