z hop not working
I still get scratches on my prints. I have activated z hop from 0.1 to 1mm and it still runs over my surface scratching it. and retraction is inconsistent. I use the marlin firmware. Do I need to set the number there?
I meant, do i set the z movement there?
Normally the slicer should add the z-hop commands. If you use UltiCode flavour this must be set in firmware. You should be able to see it in th egcode if it should hop.
Does a retraction also happen when it z hops?
Normally yes. First retract then z hop I think.
