Hi, I am playing around with adding a heated bed to my Flashforge Finder. The result is that the bed is about a 1 cm higher than stock. I can't use the Flashforge slicer, so looking at Cura to get around this, given the Finder can be configured as a printer in Cura - at least according to multiple videos on the topic. I accept the build volume will be less. But has anyone a suggestion on what other parameter is to change to set the higher bed position please? Cheers, Baz
