Why am I getting this error message?

After slicing in Creality Print V 5.1.0.9484, when I try to one click print to my printer, I get the following message:

“The slicing model is inconsistent with the printer model. Inconsistency will cause deviations in the print. Do you want to continue?”

I am using the Ender 3 V3 KE, and it is the machine chosen in the slicer.

Any ideas as to what may be causing the issue.

Bad STL file? Try to look at the STL with Meshmixer, there may be something odd with it. i find it happens mostly with scanned parts made into STL. Using Meshmixer to trim off a little can fix things.

I got the same message because I changed the nozzle type from brass to steel. Using the brass nozzle and no more error message.

I’m getting the same thing. I use the same file with 5.0 and no error. This appears to be a new bug in 5.1.

I have the same error message with my K1 Max. But only if I create the K1 Max as a custom printer profile. This message does not appear with the default configuration. And even if I switch the custom profile to brass nozzle, the error message still appears, even though that is the only difference between the profiles.

Just ‘upgraded’ to 5.1 and I get the same error. Same model sliced in 5.0 gives no message. Using a K1C.
