Good question Perry- This is one use of a hundred mods/uses you can do with -3d Inmoov-
This mod allows the servo and gear to be positioned by just loosening and tightening the grub screw- You send the command line to the servo to adjust its position,,—,,then adjust the gear to the position you want,,, and then tighten the screw ,, I wasn’t sure how good the grip would be,,, but it is fantastic,, strong as hell- the grub screw pushes the servo spline into the plastic –make it nearly impossible to strip–
