@craig607 great to see the stepper functionality and managing it with the GCODEs though I wasn’t clear what the Marlin board is, and how it gets activated. Is the relay the power switch ON, or

This probably says how basic my view is, looking at powering, the 4.2V is nice as it maps to a LiPo battery, though LiPo are 4.2V decreasing to 3.8V. With 1.5As power draw the battery needs to be sized for the length of time the pumps can operate.
I’m imagining a use case of it being solar powered, so guessing at a separate LiIon battery pack, with probably separate charger and possibly solar panel – possibly all in the Marlin board? Just checking. Also, thinking typically need to measure the LiIon voltage to check its being charged.
