Mr Aardvark Thank you for the response.

Right now everything seems to run perfect. I have not tried to do a print yet but I have checked X,Y,and Z and their zeros. I have checked heated bed and heated the heads and pushed material through them with ease.

I will check all the bolts tonight before I try to run anything. The slide rods will get a lubrication also.

So add this fan in conjunction with the OEM fans. OK.

I have had nothing but great luck with Kapton on our other printers. When I have tried blue tape it has been way too difficult to remove. But I will see what happens here with this one.

I will give the PEI a try. How well does it heat up with the aluminum plate of the build plate?
