Design flaw or assembly error?

Post by jumpjack » Tue Dec 17, 2019 5:19 pm

I cannot understand the reason of this design decision:

Those "special nuts" (don't know english name) are specifically designed to be easily tightened and loosened by hand without any tool, just by bare hands... but they must be freely accessible to do that! Instead, they have been placed on the lower side of the printing bed, making it quite impossible to reach them, especially during printing, and especially the two ones behind the printer!
So I dismounted them and mounted each screw assembly upside down.
Now calibrating the printing bed during a print is quick and easy.

But I will have to cut away a small part of each glass bed corner, as they prevent the nuts from freely rotating.

Weird thing is that at beginning of each print the nozzle goes up 10mm from home position, and only after that it reaches bed center: it's like it's programmed to avoid the "special nut" on the origin... although it's not there.

Hi, It is better to fix the hot bed in the way shown in this picture;
Because the print model is generally set to print in the center of the hot bed

This is to prevent the moving head from scratching the surface. ;)

As you've noticed, the nuts are difficult to access.
However, nothing protrudes at the top, so there is no chance of a collision with the moving printer head. :geek:
