In Cura 3.2.1, the Monoprice Mini's profile looks good when printing PLA. However, switching to ABS loses the Ultra Fine quality.
Here's PLA:
Ultra Fine: 0.0437mm
Normal: 0.175mm
Low Detail: 0.3063mm
Finer: 0.0875mm
Fine: 0.1313mm
Fast:0.2188mm
Draft:0.2625mm
Lowest Quality Draft: 0.35
With ABS, there is no choice for 'Ultra Fine', but when selecting "Draft", the layer number is correct, but the description says "Ultra Fine".
