Hello everyone, I am trying to use the extrusion port on Ramps 1. 5A so you can set the E motor to 850mA safely using the stock stepper drivers. Cold extrusion produces parts with close tolerance, high strength, and requires minimal finishing. This striking is accomplished with a punch or ram in a closed cavity. Just tested it multiple times. I am aware that stepper drivers can briefly pause motion of the stepper motors to cool off but in this case the pause only start to happen after pronterface shows. I thought 75C sounded very cold as well, but I took the advice as I am new to dual extruding, and thought it might help. The final stress state is determined by the combination of two process stages: forming and ejection. The advantages of this over hot extrusion are the lack of oxidation, higher strength due to cold working, closer tolerances, better surface finish, and fast extrusion speeds if the material is subject to hot shortness. 2) Is it possible to eliminate, or adjust, "the cold extrusion prevented" block on manually extruding fil using pronterface?
