There is plenty! CartFarm stuff works extremely well. I have no qualms there, except saying the only difference in precision is moving between carts. Repeaters have a place, but by their very nature require tradeoffs in viscosity and accuracy / repeatability.
We have one, but again it’s built for a slightly different purpose. It doesn’t get the speeds that repeaters do unless you really crank up the params (Temp, Pressure, Etc) beyond what we recommend or advise. Even after that, our pumps are designed for accuracy and viscosity over speed.
Not trying to dig on QMA’s products at all, they are damn good for their intended purpose. I believe his arguments against automation and the benefits of it are incorrect.
