I would say that 85% or more of my “crashes” happen because of dust collection - either the Sweepy contacts a clamp, the hose gets trapped between the rail and Z, or the hose gets caught on the back of the gantry.
My hose comes off an arm at the top right of the machine…and I’ve remedied most of the problems with strategic positioning of baffles for the hose - but I really should have the hose come more from the center on top.
The other thing that would really help is the “Frame” command (requested for CM) - to move the gantry around the perimeter of the project to show you where contact might be made with clamps.
