  1. I am finding that the load material cycle is not long enough to purge old material out of the core.  I am pushing filament into the feeder until it just grabs (about flush with the top of the feeder).  Obvious thing to try might be to poke a bit more filament through but this usually leads to the filament bumping into the core and the feed gear ripping a lump out of the filament and stalling.  I am only able to get around the problem by manually pushing filament through to purge.  Of course with the material and feeder situated around the back of the machine (genius) this is all a bit of a pain, is there a way to extend the load cycle?

  2. It helps, but doesn't fix the problem.  The design of the machine should be such that a process which has to be completed before every print is't so prone to failure.  If the answer is to remove every little speck of material from the nozzle then build in a wiping system or if the bed needs damping then build it in.  I for one am sick of cleaning everything down and then having to stand over the machine watching it auto bed level each time to make sure it works..I might as well manually level the bed!!!!

  3. Hi

     

    We have two newer Ultimaker s5 machines which very frequently fail on auto bed levelling. I have manually levelled the bed a number of times but this does not improve the situation.   The older machines we have never fail on auto bed levelling.  Is this a case of a bad recent batch of sensor boards?

  4. I had problems on Cura 4.9 with material retract on extruder 2.  It seemed that the material was retracting on extruder change but was not going back ready to print.  Going back to Cura 4.8 rectified the problem.
