I’m new to 3d printing. I have watched a few videos, I have read some posts here, but I. The whole I have no idea what I’m doing. I’m looking to learn.
I attempted to print a digital sundial yesterday on my ad5x. The fine detail did not work, the bridge like sections just seemed to mess up. I’ll try to attach a photo. I printed it in abs, using the printers recommended settings for abs, I used the designers recommendation to reduce layer height to 0.1 from 0.2. My ad5x has the enclosure fitted. My guess would be nozzle size, I used the 0.4, but I don’t want to buy one if it is not that.
What did I do wrong, I assume this is user error, but I don’t know how, any advice would be appreciated.
