Thank you for the excellent work, I appreciate!
- you added a second linear rail to the x-axis in f3d. But this is not used by the x-carriage frame AFAIK. Was that just an Idea to get it more sturdy and did you experience any problems wit the stability?
- The center of gravity is quite off the belts plane. Did you notice any probs with that and do you see a chance to get closer?
- My Ender-4 had a rather wobbly bed, until I added a second Z-leadscrew
- what else could be worth thinking about?
