Stringing Retraction Test

thingiverse

I couldn't find a stringing test STL that I liked, so I created one. This one has a base of 5mm tall and has numbers added so that you can customize your slicing program to change retraction distance every 10 mm. Total height is 55mm. I use Cura to customize retraction settings to change at specific heights. You can find the settings by clicking Extensions>Post Processing>Modify G-Code. From there, you will add the script ChangeAtZ for each step. Make sure your initial slice settings have retraction set to 0mm and desired retraction speed. I start retraction speed at 50 mm/s and adjust if I need to. Add Script and change the following for each Z height: Height: 15mm Apply To: Target Layer + Subsequent Layers Enable Change Retraction Retract Length: 2mm Height: 25mm Apply To: Target Layer + Subsequent Layers Enable Change Retraction Retract Length: 4mm Height: 35mm Apply To: Target Layer + Subsequent Layers Enable Change Retraction Retract Length: 6mm Height: 45mm Apply To: Target Layer + Subsequent Layers Enable Change Retraction Retract Length: 8mm
