Also you should note the orientation of the filament spool. The other way is functional but far from preferable. And as you reach the top of your build height you might end up breaking some filaments. Which just blows at the end of a really long print that would see the max build height achieved. I have had such great results from each and every time I applied a second motor to an axis that I am thinking now about a printer with no idler pulleys. 2 stepper motors on opposing ends of each axis. This printer will use 7 stepper motors and 7 stepper motors drivers for 1 extruder. I think 10 if we want to use the MMU2.0 stuff which I very much do. Can you imagine a printer with 10 stepper drivers? Sounds far fetched, doesn't it? I think i'm gonna do it. For this effort I will just print another motor end for the x axis and replace the idler end with it. This is such an incredible hobby because there is so much freedom to just be creative here.
