Paste extrusion with pressure regulation
Description
This Set-Up Is Used To Print Highly Viscous Fluids Or Pastes. From A Central Compressed Air Supplyment The Air Is Lead Through Pressure Regulators And 3/2-Way Valves To The Syringes. An Electrical Circuit Containing Solid State Relais Controls The Valves. The Switch Signal Is A Gcode Command That Triggeres An Unused Arduino Port (Marlin Firmware). To Insert These Gcode Commands Before And After Each Travel Move I Used A Postprocessing Python Script With Slic3R.
