Speed Test Tower

thingiverse

I wanted to see how fast I could push my printer and still get quality prints. I couldn't find a good speed test tower, so I made one. Here is the gcode I used in Slic3r PE (goes in printer settings, custom gcode, after layer change) to change speed at the various layers : ;[layer_z] {if layer_num==5}M220 S120{endif} {if layer_num==77}M220 S130{endif} {if layer_num==152}M220 S140{endif} {if layer_num==227}M220 S150{endif} {if layer_num==302}M220 S160{endif} I started with a base print speed of 60mm/s, and once completed, looked for artifacts, ghosting, etc until I determined the optimal speed the printer could print and still maintain quality. Using this method I was able to test print speeds from 72-96 mm/s in one print.
