Sunhokey i4 X linear Rail support

Do to the small lash in the X linear Rail I make a support guide and attached a new Linear Rail on the X axis (270mm) this is so much better now and run like a dream, much better quality in fast print.
I change my new linear rail with one of the z axis, do to the Black color, the new was in steel color. I also heated in some small Brass tread. Watch out, this is not easy, try on an old print tol earn how to do it, or use small bolt insted.

I make a small video of the Work, speed is X8, it`s NOT a" how to do" but a "see how I do it"

NOTE: you can download the file in 3mm and 4mm bed Mount hole. if you want to try heat in the small brass tread use 4mm hole.
