How hard would it be to use MGN15H? Had a hard time tracking down MGN12H rails. SO i ordered MGN15H.

Did you switch the x axis to mgn12 as well? I’m looking to build a mgn12 CoreXY for my next project... I absolutely love the way your titan aero x carriage design looks... probably the best looking x carriage I’ve seen so far (kudos).... would definitely go with your design if you implemented the x axis as well :)


why bottom profil better ?

I've seen a couple of other designs around...one top rail which looks pretty good, and one side rail which I have not studied. I like bottom rail because it might collect a slightly lease dust over time. I also cleaned the lube off my rails, used a dry lube and cover the printer when not in use.

Could you add source (fusion360 or whatelse) to modify for 3030 and 2020 profile?

Hi! I published link to fusion 360 sources in description.
