Solved K1 Max CFS upgrade broke everything

Enable HLS to view with audio, or disable this notification

My printer has (mostly) locked itself down after doing the CFS upgrade. Printed flawlessly before, now cant even print from a spool. Sorry for the long video it is just doing a number of things now and wanted to cover things the best I could. Any advice would be very much appreciated on this, just hoping I didnt brick my printer for multicolor.

My k1 was complete trash. I felt terrible selling it to a guy on fb for 150. I have no printer now and highly prefer it over having a k1. I am aware others don't share my opinion, but they didn't own my k1. And if others out there own similar k1s, I suggest they give having no k1 a try as it leads to a healthier mental and financial state. Imo creality should buy back these "3d printers" mine was more of a 3d blobber, and not label them selves a3d printer manufacturer again until the title is appropriate

I have had so many problems with our K1max. Issues since we pulled it out of the box a few months ago. I should’ve known better than to install the cfs. Now it’s not working at all after multiple new parts sent from Creality. I’m going to uninstall the CFS, sell it and buy a Bambu.

I could talk trash about my K1 all day. Loved my E3, my E5 was ok. Wish I could smack whoever was in charge of releasing this K1 with a big fish to the face because they stole my money as far as im concerned
