Disable Z hop after a certain layer height


Recommended Posts

Posted · Disable Z hop after a certain layer height

Hi all, following this video I was playing with Z hop to print an inlay on the bottom of my print (the TL;DR is print the small inlay first, then print the rest with Z hop enabled to a value higher than the inlay height). It works well, but there's a caveat: on a printer with an imprecise Z axis (like my Ender 3), having Z hop enabled can lead to a messy print, as the imprecisions on the Z will sum up quickly with every hop.

 

Leaving aside the obvious fact that the Z precision should be high enough to be able to use Z hop for the whole print, the next best way would be to disable the Z hop right after the second print height has gone above the first inlay height. I couldn't find an easy way to do so (I had to manually edit the gcode), would it be possible to have this option, either in the post-processing or as an option for the Z hop?

 

Thank you.
