AM8_V-slot mod

thingiverse

I am redoing the AM8 project for Anet A8 under the V-slot profile. I recently printed a new Z rail mount with an improved design, it does not have any backlash. The last modification has not been uploaded yet. Added reinforced motor mounting to Z axis. Added mounting bracket for 608 bearing on Z axis at request of kusjanja. Added mounting bracket for display screen taking into account time spent on it and made it a separate entity https://www.thingiverse.com/thing:2670121 Modification for AM8_V-SLOT to eliminate backlash from Z axis, starting with X and Z axes https://www.thingiverse.com/thing:2649422 New belt tensioner for Y axis https://www.thingiverse.com/thing:2611692 Added a new bearing holder that is self-tightening and more compact. Update 26.09.2017: 1. Y_motor_mount_mod design failed, it bends when the belt is tightened. It may not be noticeable if printed at 100% fill rate, but it's suboptimal. A larger lever is not good. 2. I changed the endstop mounting from screws to simply inserting them. I will post it later, as the screws for the Z axis endstop are located horizontally on the profile, and it would be better to have them vertical. Additionally, this is a temporary solution until I replace it with an inductive sensor. 3. The non-amortized couplings should arrive soon https://ru.aliexpress.com/item/50-pcs-Coupling-Coupling-For-3D-printer-accessories-CNC-Engraving-Machines-DIY-Aluminum-Coupling-5-8/32705413192.html After testing, I think I will combine the Z axis motor mount with the vertical profile mounting, as adjusting the height of the Z axis motor is not necessary, and it should result in a stiffer and more aesthetically pleasing design.
