@neilh20 so the board here is called a MKS Base V1.4 if i remember correctly. It’s an old 3d printer board. There are a slough of options and which is used really doesn’t matter. They are all, like the mayfly, a modified arduino. Though these use the arduino mega as their main design.

I have the relay controlling the power to the board itself.…[Read more]

@neilh20 For my sediment machines I use a high torque 920z Nema 17 motor and is rated for 3.36v and 2.1amps. It works very reliably. The one I prototyped is a 76oz Nema 17 which is rated for  4.2v and 1.5amps. I have a pancake motor as well but they are lower torque. Here is a reference to a number of steppers from the 3d printing side of things:…[Read more]

@heather, I would consider that. I still need to figure out the details on implementation and code.

The pump project that I used can be found here: https://www.thingiverse.com/thing:3148717

Here is how I currently put this strategy into action. A wifi connected outlet turns the machine on and off.
