I was feeding TPU into the extruder like the instructions but nothing was coming out, so i took the front of the extruder casing off to see if there was any jam. The extrude button is directly above the unload button which i accidently pushed, the hotend shot towards the front of the case and then to the left side before i could do anything, crashing the casing in both directions before i could turn it off. Luckily only scuffs that i can see but could have been much worse. Could the head be disabled from moving when it knows the front cover is open?
