Z-axis motors question...

Hello -

My MK4S -> CoreOne kit came in, finally after a very long wait.  I've taken the MK4S apart, lots of parts in ziplock bags and labeled.  Starting the process of building the CoreOne. 

I took the new Z-axis motor that came in the kit and compared it to the two I have already.  This is what the motor labels look like:

The NEW motor that came in the kit is on the left.  It reads:  "ORIGINAL PRUSA".

The motors that were on my MK4S are in the middle and the right.  The label reads "ORIGINAL PRUSA I3".  

Question:  is this going to be a problem?  Are the motors mis-matched?  

I also see the face of the motor mount is different.  New motor on the left, the other motors on the right?

Thoughts?  Is this a concern or no worries?

Thanks!

Not a problem.  Your MK4S is actually an "i3 Mark 4 S". The Mark 4/MK4 has the same specification motor as the CoreONE.

Mine are the same way, so far so good, no issues on the z-axis to speak of.
