After slicing my project and select to send to printer (K1c) I receive this message.
‘The slicing machine is inconsistent with printer model. Inconsistency will cause deviation in printing effect. Do you want to continue printing.’
The printer set is the same I used in version 5.0. I do not receive this message when using v 5.0

I don’t know if this will be helpful to you, but I encountered this problem, by accident. The problem was the wrong type of nozzle selected in the CP settings.
If you are using a custom print profile then try it and check on the default settings.
Thanks Luten, I did change the nozzle type to harden steel, Did not alter the error message. Started v5.1 today for another print and the software crashed and lost all printer configurations I have deleted 5,1 and returned to 5.0. I may try for a clean install later.

im liking everything about the new 5 and 5.1 only thing is those darn presets are gone for all the printers. I used a one of the 4 they had selectable that was close to what I have and altered the setting they had in the preset to the ones I have in other slicers mostly I used reality print 4.x and got my basic settings from there.
I get the same error, and I had other issues with 5.1 as well. I went back to 5.0, other than an occasional crash, it’s worked fine for me. I’ll wait until they work more of the bugs in 5.1.
Software crashes randomly, some time doesn’t allow for opening gcode files, losses connection to the cloud and connection to the printer including camera fails.
Just tried v5.1.1.9490 and it crashed my K1 about 1 minute into a print. K1 is at the latest firmware. I also got the message “… slicing machine is inconsistent with printer model…”. I guess it means don’t use 5.1. So I don’t. Switched back to 5.0. So glad the 5.1 install didn’t remove 5.0.
Yep, I was thankful that 5.1 didn’t tinker with my 5.0 installation, that would have upset me a lot! 
Getting the same message after using Creality Print v5.1.1.9490. Error does not happen in v5.0. Really annoying that you can’t export filament settings from v5.0. Using a K1C
How do you submit a bug report on the Creality print? I still get the same error as well, I just downloaded v5.1.1.9490 in hopes they had fixed it. 
Does anybody know how to set the Material Cost?
Yes, click on the material in the filament pane at the top. Click on the pen for edit. Near the bottom you will see price.
Thank you for that.
Just for anybody else that needs this, you have to be in ‘Advanced’ to see the Price.
