Also trying out printing text. The top one was done with a 0.4mm nozzle, the bottom at 0.25mm. The best standard font I have found is Roboto Bold, though for what I am doing I only need Upper Case letters, so haven't tried Lower Case.
It doesn't seem to be a standard part of Windows but I found it in OpenSuse Linux. I printed both very slowly, as you can see I had some problems with blobbiness here and there. I printed with a 0.5mm depth and very slowly and with a 0.1mm layer height, I am going to try 0.3mm and maybe 0.2mm depth and see if it helps reduce/eliminate the blobbiness.
