Using the underframe it might be a little bit painful that the height of the guide is somewhat lower than it should be.
So I created a litte jig that you can clip on. Resize it to any length you want in your slicer, I found it easier to print a bunch of small jigs instead printing larger ones. You need 50+mm total.

Just clip them on and remove them fast if not needed.
