I've been away for a while but now I'm back and want to get on with 3D-printing ... but first I have to find out, what is wrong !
Because I did NOT change anything from the RED (fine and OK print !) to the GRAY ratchet (useless print !) I don't think I should change any 'settings' - and later I did delete ALL my profiles and use the
WHat I HAVE done right before the problems started is cleaning the extruder - when I put it all together again I maybe changed a little of the position of the TIP of the nozzle compared to the BED.
I therefore did a MANUAL levelling of the bed 3-4 times and then did a automatic levelling in the menu BUT do I need too to somehow 'reset' something concerning the "Home-position" in the SW ?
