To print in multi resolution: to edit your printing process, go to the “Advanced” tab and check “stop printing at height”. Then enter the height for this process with the desired resolution.
Validate the process, then click on “Add” in the processes. This will create a second process identical to the first. Edit it and by going to the “advanced” tab, uncheck “stop…” and check “start printing…” by setting the desired height and the new resolution.
Slice with the 2 processes and your print will be multi resolution.
