I can print at over 100mm on a Cerberus which is a variant on Johanns Rostock and the second delta I've had in the last 2.5 years. I have this issue running at 80mm.
I know my machine can print at 200mm but Im patient
I love this sparse setting but....well you know.
I tried printing at 1.5mm height so the sparse would be 3mm but I still had minor skipping.
I wont try 1mm height as the speed hit for the overall job becomes too slow.
My infill when using sparse is more or less good enough but the skipping is annoying and plastic that dries above the plane Im printing on causes the head to sometimes hit it giving me whiplash when I hear something out of the ordinary.
I am using a .5mm nozzle. Temp is not the issue nor the diameter setting for the filament I'm using.
Everything is perfect till i use the sparse setting.
