One of the projects we are attempting to print has in the instructions to not include a top or bottom layer. Roboprint does allow me to change those settings for the top amd bottom layer but 1 layer is the smallest I can go.

I tightened this belt and all noise went away. As per usual the belt loose made a thud when...
