Wont level key2194 error

HI my ender 3 gave of a key 2194 error after it finished off a print and i started a new print. i have tried re-flashing software and the fix creality gives with no success. Has anyone else experienced this error and if so were you able to fix it?

Check that none of the connection pins to the hotend aren’t bent, a bent pin can cause that error.

What does the error mean?
I just started getting this error too… after a couple months of successful printing… no change on my part to the process I’ve been following… just started to give this error and disallow printing yesterday.

seems to be a bed levelling error, either the corner sensor or the CR touch, check the connections to these parts. I have yet to find a strain sensor/gauge for the V3SE or KE printers. I can find pretty much every part to build the printer from scratch just not this part.

Thanks, so I guess over time the connection may come loose or a bent pin that was making contact initially has finally become loose - I’ll check it out.

Getting ready to chase down bent pins, but another error popped up for more detail… clarifying it’s a leveling anomaly. I can ignore or I can ‘bind’ to the Creality Print Cloud. What Does binding mean? I assume it’s connecting my Ender3 to the mothership back in China.
Anyone had any issue with that yet?
