I just got a GeeeTech Rostock 301 mixer head delta printer and am having trouble honing in on why the extruder is struggling with my first spool of ABS.
Being the main parts of the printer came assembled I am unsure of where to start taking things apart. I have a read a multitude of possible causes and am hoping for some direction on which is most likely so I can start there.
Extruder clicking. The extruder makes a low grinding noise every time it tries to extrude more than 1mm of filament using the manual controls. Again I am working with ABS so I have the hotend heated to 250 degrees C. The extruder had no trouble when I was first putting the filament in and using the extruder to push it thorough the Bowden tube.
But when I tried using the manual controls to extrude a small amount of filament it seems to be fine, just a small time delay between the extruder moving and the plastic coming out of the hotend.
Things I have read to try
Again this a kit printer and the involved components came assembled (see below) so I am not sure what I should look at first. I assume that if it came pre-assembled then it is most likely done correctly.
- Clean out the hotend, do a cold pull
- Take apart the extruder and realign the driving cog, check for shaft slippage
- Replace your Bowden Tubes
- Tweak slicer settings
For the first 3 I think its new so it should be clean, in working order. And for number 4 I put what was in the manual except for the temperatures (because the settings shown in the manual were for PLA but it is a PLA or ABS printer)
So aside from wiring and mounting these pieces the only thing I did was cut a clean edge on the Bowden tube and connect that to the extruder.
