Well if that's how it is, make sure you connect all hoses from pump directly to cylinders and then use a toggle switch to activate the pump!! Should get the Rams screaming!! Lol!!!!

All kiddin aside, don't worry about getting them smooth, first get your pump and pressure settings how you want. Then use the limiting of your servo throws to (end points) adjust how far they open. That will allow the cylinder to be fed by less volume but same pressure. I forget where I have mine set but everyone will be different. Like boom down was almost 30% if I remember correct. Weight of bucket, stick, boom, and gravity help on the down. Any drifting should be one of two things, valve is not centered or compromised piston seal in cylinder. That was the problem I had with my stick cylinder, the piston came loose on the shaft and oil was bypassing the piston/seal allowing for drifting. But get the valves centered, pressure set, pump speed, prv ect before you try and smooth out movements. And most likely you don't have to have the pump screaming to make pretty good pressure. Really need a pressure gauge. Doesn't have to stay in model but for setting the pressure from time to time.
