I was using a roll of Inland filament last week, and the diameter of the filament kept getting wider as the roll was used. It eventually clogged my machine, and did some damage. I had to replace a piece of Capricorn tubing going into the hot end, the nozzle, and now I've noticed that the servo has no power. It was struggling for an extended period of time trying to force filament through. Since I have a direct drive set up, I want to use the strongest servo which is available with a 39MM thickness which is the size of my stock servo. I've narrowed it down to three options. This one appears to have the highest torque, and requires 1.5 Amps: https://www.moonsindustries.com/p/n...tepper-motors/ms17hd2p4150-000004611110008900. There are two other options. One is similar but it requires 2 Amps. I think that it's not as efficient since the torque rating is the same. The other option is a 1 Amp model with a slightly lower torque rating. I'm attaching a PDF spec sheet for all three servos.
