After a day of adjustments and tweaking, I finally have the bot all assembled. Next step: Smoke test!
I started with testing the heater element. A little bit of smoke as the heater came up to temp, but otherwise, everything seemed fine, and I was able to get temp to stabilize around 220C.
Next, I put a short length of abs in the extruder and turned on the drive motor…
Success!
