[kovarex] [0.17.9] Splitter 2->1 has output gaps even when 1 input is saturated
Posted: Sat Mar 09, 2019 4:52 pm
I was testing a 4-belt-per-wagon unloader, but I couldn't get it to produce fully-compressed belts, even though the final splitter(s) were backed up on at least one of their inputs. I reduced it to a minimal example, directly north of my position in the attached save:
Note the inserter stack size limited to 2. The bug seems to be timing dependent. If I delete the belt in front of the inserter, wait few seconds, and rebuild it, the gaps don't reappear immediately.
The instrumented examples, to the south, show that the bug seems to be related to the items on the belt arriving 3 ticks apart. Given that 3 ticks was the item separation on the old 40/s belts, that's highly suggestive of a possible cause. Maybe there's something in the splitter code that needs to be changed for high-density belts?
