That is a good point, would be easier I agree, I think I did it like that because it is needed to be done like that for MK2(S)/2.5(S).

Thank you, it has been fixed.

I thought about it too, will keep it in mind.

I have seen this problems once too, I have an improved version in the work to reinforce this section.

The clipping of the smooth rods is strong enough, you can flip the printer. I have decided to put them at the end in case smooth rods needs to be removed for any type of reason.

Yes a little spacing is possible :)

Good point thanks, I have added it :)

Sure you can, or Bear Calibration firmware, as you wish, both will do the same job.

You can use the build_helper_z to align both top and bottom alternatively, tighten the screw little by little and correct the plate position with the tool. Otherwise using anything flat as proposed is a good solution too.

Good idea however the new frame does not have the tapped holes anymore.
