there is just a little problem I am facing with my 3D prints at the moment.
When the extruder heats up there is a "worm" of filament flowing down the extruder.
This leads to no filament being applied to the plate for the first seconds.
Is there a procedure (Gcode) to be added to prime the extruder for a short moment after homing the axes and the go to a position with a pin or something similar to peel the excess filament from the nozzle?
The phenomenon you write about is natural.
You can try to limit its occurrence.
In the additional "End code" commands you can add an instruction to withdraw the filament (retraction), so that it is executed
after each completed printout.
This is done in the slicer program.
This is first of all..
Secondly, you can add an instruction to the "Start code" script, which will give you a little bit of filament just before you start printing.
But then it is important to reset the filament counter.
Code: Select all
If you have any problems, ask.
