Hello All,

I got a Bocusini Paste Extruder from a Kickstarter pledge about 18 months ago, and it has taken me this long to source a suitable printer to install it on. It is essentially a syringe type paste extruder with a geared plunger and heater. Now I have finally managed to install it on an UM2 extended, I am starting to wonder whether I could just use the regular UM2 (modified) firmware rather than their restrictive proprietary one. I am not intending to print food, but rather silicone and other experimental paste materials. The motor that normally runs the extruder here lowers the plunger to squeeze out material. It's not too different from the way it usually works. Do I need to adjust the E Steps/mm and acceleration? If so, how do I do that and how do I calculate the new settings? Is there anything else in the firmware I might need to modify?

Any help at all would be much appreciated...
