Mendel X Axis Motor Bracket
by rhys-jones, published
The previous Mendel X bracket was compact, but led the toothed belt along a tortuous path with tight radii and reverses of direction. I've had the X axis belt snap (which costs far too much!), after just 4 sets of Mendel parts, and others have told me the same. With this, the design is larger, but less prone to belt failure. We've printed about 8 Mendels with it now with no sign of belt wear.
The X-axis ground rods need to be shorter, at 463 mm long. Also the X axis spacers and two sets of bearings and associated fastners are no longer needed. The motor is attached by 4 shorter, M3 x 12, cap screws not on the original BOM. Finally, the belt needs to be attached inside out compared to before, and as such the motor direction needs to be reversed.
