Worked first time! Newbie got lucky I guess.
I used the default High settings (Extra Fine vs High vs Fine) on my new QIDI X-Smart printer. I did turn-on the Z-Hop When Extracted, to be safe. The final result is a little rough in spots, but works great! Amazing! Thank you for the design! Took 19 hours. If there's a next time, I'll try the lower resolution Fine setting to see if that works.
