It's not the real issue. I introduced that while anonymizing the data. It's that a 3-5 liner code became a huge switch case by just incrementing the code and never thinking how it should be done. This was caused by like 15 engineers in time :)
Something like below would be huge improvement:
subs1 = ["cluster1", "cluster2"]
if subs1.contains(clusterName) return subs1
Unfortunately odor level != poison/voc levels. Even though I am not following my own advice and don't use full on respirators while resin printing, it's still wise to use it at all times not depending on the train type.
Located in Ireland, but I can find similar ones.
