I've been running Sprinter on a RAMPS 1.4 control board for my MendelMax since I built it a few weeks ago. This is the most common firmware in use, with the most community support. However there are other firmware options that are faster and more cutting edge, at the expense of having more bugs and a smaller user base. Today I switched to Marlin because I read that it handles acceleration between moves more smoothly, and can draw smooth arcs as well (a much more experimental feature). I chose this funnel as my test print because the cone and cylinders comprising it cover a range of arc sizes. On the left we have a print with Sprinter. There is a strong ridge at the layer change point near the left side, and additional ridges on every edge around the model. This print took about 40 minutes. In the middle is the exact same gcode run by Marlin. The edge ridges are gone, but the layer change ridge is more pronounced, especially on the cylinder at the top. This is much closer to wh
