Re: Rostock Max vs Kossel Mini belt system
If you put the motor sprocket under the T/V-slot extrusion and the return pulley above the extrusion, the belt can ride in the slots and you will not lose any Z height. Picture this on 2020 extrusion:...

What about stabilizing the extrusions to the other extrusions? Won't you lose z height?

Cura seems to produce less stringing for me. Slic3r has better features such as overhang detection. Slic3r is a bit slower (although allocating more threads helps, if you've got the memory).

Why is it a problem if the idler slips? It does not turn the belt, and less friction is desirable. There are thousands of MK's in the wild that use the flanged bearings as idler pulleys, because they...

Hi RDM6 We have found there are no issues with using an untoothed idler, rather than an pulley, however i have seen a design using a pulley as well. Cheers Tony
