Toolchanges Without Tip Shaping or Filament Cutter!

Because the 3MS is synchronized to the printer's extruder, it can perform toolchanges without any tip shaping or filament cutter.

Should Tip Shaping be Used?

See Materials for information on whether or not tip shaping should be used for your filaments.

Slicer Setup

Setup your slicer for no tip shaping as follows.

Disable Filament Ramming

Disable filament ramming in Filament Settings -> Multimaterial -> Toolchange parameters with single extruder MM printers:

Unload/Load Speed

Next, change the Unloading speed at start and Unloading speed to 300 (faster is better here). Next, change the Loading speed at start and Loading speed to 300 and 100, respectively.

What this does

The main idea behind toolchanges without tip shaping relies on the filament being unloaded too fast to form a blob. Setting the Unloading speed settings allows this. Next, loading the filament back can be generally optimized by increasing the Loading speed settings.

Temperature

If your filament has very long strings on the end of them after unloading without tip shaping (longer than 2cm), decrease your filament temperature.

If your filament tip has a nearly flat tip, increase your filament temperature.

The ideal filament tip has a pointy end and a small string (less than 5mm). When in doubt, it is recommended to aim for a slightly stringy tip over a flat tip.
