After several tests I can say that there are certain problems with the excavator. When using an excavator on those algorithms that are supported by miningpoolhub, we get zero speed.
Therefore, you need to either force the excavator to work with miningpoolhub, or delete the algorithms that support miningpoolhub in the * .json file if you want use miningpoolhub.
Then I again ask you to include in the next release the miner from palgin for neoscrypt and hsr algos https://github.com/palginpav/hsrminer/tree/master/Neoscrypt%20algo/Windows
https://github.com/palginpav/hsrminer/tree/master/HSR%20algo/Windows
Because palgin the best miner at neoscrypt algo for pascal based cards and it works with miningpoolhub
