Creality Cloud - I NEED HELP!! I'm trying to print a Glock 17 frame. It is a FMDA DD17.2. I'm using my Ender3 V3 KE printer. After the 25 point self levelling it goes into print. Just before the line on the left.It stops, an error message pops up, it says: Warning, (it shuts down at the same time) key 2171 unknown exception ANY BODY ever seen this or knows what is wrong. I did try 7 different models the same.. Any ideas will help.. Thank you Phila. From Philacop1 https://m.crealitycloud.com/en/post-content/65dc236d96ef231d8fcd168a
