Burns through fuel a bit too fast, I have 2 farms going and it still runs out at times.

You may have your zombots setup badly. my setup makes enough I have full grown plants that takee a bit to be harvested cause the storage is full with just one farm. Though I do use two pylons for my farm. I have 3 bots in one pylon digging holes with pickaxes, and 3 in the second, one of each plant type cause I wanted variety. You could probably do it all with one pylon if you don't care about having all 3 types of plants.

all 6 are set to use, collect and hurry.

I have a full pylon set up dedicated for farming. 2 configurations (2x10 zombots) are planting, 1 configuration (10 zombots) for pickaxing the floor for the planters. It's definitely over kill now and I probably should decrease it a little as it seems I maxed out in 20 minutes (although I don't need more zombots for anthint else). But you should really get a huge chunk of your zombots dedicated to farming temporarily. Then decrease over time if needed, to see how much you need to keep up with supply
