Speaking of bedrock gearboxes ... I managed to get a bedrock breaker running with a buttload of chained hydrothingies.
But I noticed that bedrock on my map is just levels 1 & 2, so it's turning but not actually grinding anything. Shouldn't RoC create a ticker bedrock layer tick enough to have some meat to munch into?
Someone suggested going for the nether roof instead, but that means I can't use my hydro engines
Can you verify which version you are running? Bedrock Breaker is one of the machines that gets a lot of attention, so it can change behavior version to version. Also, check your config for anything relating to it. Monster 1.1.2 has v23b, and it can absolutely break the bedrock at layer 2 in the overworld. I know because I did it
Or, through the glory of Geostrata time accels, you can get a single extractor running at x128 it's speed with only the minimal power/speed/torque required!
(or x256 if you can be arsed to kill the wither 5 times extra)
I'll have to look into that. I've never used it, but I have also always had problems with various time accelerators in the past.
