I saw online the warnings about handling the calibration probe, and being very careful with the nozzle tips. Putting those gently aside, I tested the rotation of the cool gear knobs while I was reading the assembly instructions for the extruder dispensers.
I had a little trouble getting the conductive paste tube into the syringe mechanism-
The labels on the tube make for an increasingly tight fit during insertion, makes it tricky to fully seat the tube all the way in. Did the best I could, and then noted the green knob and plunger mechanism has a lip on it that screws down on the tube when you twist it.
That would push the tube down the last few millimeters it was sticking.
I inserted.
Twisted the assembly.
The tube seated the last bit, and
BLATTTT!!!!
About a weeks worth of conductive paste came squirting out!?
On initial insertion- if you don't return the gear knob to it's starting position, the plunger advances forward. If this happens before you've assembled the dispenser and sheath- when you do put them together- the plunger has already advanced, and you get an incident I'll simply refer to as a premature ejection.
I'm not embarrassed,
I'm sure it happens to many people their first time.
But, just like we've got to be careful with the probe, it might help to remind new users to:
Return the dispenser knob to the home position BEFORE assembly.
At $99 dollars a pop, I think we can all appreciate the importance of preserving this precious bottley fluid.
