Useful trouble shooting info


#1

It occurs to me that in trying to sort out the Discov3ry functioning, there are some details exclusively within the machine that it might help to know.

For instance:
From a ‘top down’ perspective, which way should the stepper motor be rotating for extruding material vs retracting?
Precisely how many rotations of the stepper motor produces one rotation of the rod?
Assuming I have one of the supplied syringes in the device, how many rotations of the rod will move the plunger the distance to extrude 1ml of material?

This would allow us to figure out how many steps (and which direction) of the motor we’d have to signal to push the plunger a ‘clearly measurable’ amount, if that makes sense…

Thanks,
Jim
