MPCNC Roller vs RollerM


I am reprinting my parts. When it comes to the Roller pieces, I cannot see but one minor difference between the roller and the mirrored roller (rollerM). Are they essentially interchangeable?




I have blurbs about this in the instructions and FAQ’s.

You use them in sets to prevent any sort of printing deficiencies from messing with your build.

OK, I will reprint the mirrored ones too.

I did NOT calibrate my printer before printing the first round of parts. Now it is accurate and repeatable.
