3D printing a prototype of my custom @mntmn reform 2 lid on the new Creality Ender 5 Plus.
Wow, this failed in a pretty spectacular fashion :O How can it have gone so wrong?
It would seem that the print plate was pushed off the printer and shattered. Also the print is pretty badly warped.
So maybe the piece warped, separated from the plate, collided with the print head and pulled off the plate?
On a less dramatic note, the print shows pretty severe under extrusion. That should be an easy fix though :)
The ground impact where the sheet shattered separated the shards from the print. Cooling off is likely the reason no shards are still sticking to the print anyway.
Some printers (eg. Průša MK3(/S)) can detect when the print head is moving into an object or frame part causing it to skip steps. It can even compensate and reset.
@x44203 That's pretty much what the Průša Mk3/S does. The Trinamic TMC2130 stepper drivers measure current and can detect when they're being blocked and even detect if they're loosing steps.
These motor driver chips are significantly more expensive than what's usually found in entry level FDM printer, which is why too many printers don't have that feature. (I consider that safety relevant.)
IIRC this is implemented in Marlin, so you should be able to use them.
