We have not purchased the motors or gearboxes yet so we are flexible in that sense. A rough plan was to use a combination of a flow sensor to feed information back to the system and a VSD to control the servo or stepper motor. Mostly done by digital signals but expect we might need some analogue signal somewhere. By the looks of it we only need to assign the variables that robodk generates for extrusion to set a feed rate, which for us is really the turning of our auger. As we have another system that controls the feed rate from the pump.

Is all of this on the right track?
