Title: Collision check with toolpath
Post by: OXIDO on November 04, 2025, 10:25:56 AM
Hello,
Is there a way to detect collisions with the toolpath itself? I ran the check for this piece, but had to stop because I found the collision visually.

This is also impossible to check with a big program because I cannot see where the program is, since all the toolpaths are rendered in black. With the small program, I can see that the light grey layers are yet to be printed.

let me know if you have any solutions...

Hello,

Checking toolpath collisions is currently not possible, as toolpaths are generally not a collision risk. I understand how for additive processes that may be relevant, but it would be necessary to generate a specific collision mesh for every simulation step along the toolpath - plus somehow differentiate between printing and non-printing paths.
So at the moment, I don't see any way to efficiently implement that functionality...

Best,
Johannes
