After rebuilding the extruder’s filament pusher three times due to it’s penchant for ejecting the pneumatic pushfit connector, I was finally able to get it to behave, at least at lower speeds. I’ll be designing my own instead of using an existing design at some point since the current pusher is simply too unreliable and badly designed to consider using at the speeds the Gemini is capable of.
However, all that being said – it was time to test the machine out on a larger and longer print.
This vase is 228mm tall, and 143mm in diameter. It was a test for bed levelling (larger prints need a very level print bed), Z endstop calibration (due to the methods used, there needs to be a software adjustment made to find the correct zero point) and positioning consistency.
As you can see, the Gemini prototype is performing quite well!
