Thing-o-Matic Y-Axis tensioner

thingiverse

The girdle for the y-axis servo motor should be placed beneath the perspex. To increase tension, turn a pair of bolts located on the backside of your Thing-O-Matic. Follow these instructions to install the girdle correctly: 1. Print the object and gather required materials - 2 M3x16 bolts, 2 M3 washers, and 2 M3 nuts. 2. Loosen the y-axis stepper and disassemble the bottom of your 'bot. 3. Unplug the y-axis stepper and place nuts in t-slots, securing them with sticky tape. 4. Position girdle over the stepper, nuts down, with bolts wedging it against the perspex. The girdle fits around both the stepper and z-axis endstop rod. 5. Drill holes in the back of your Thing-O-Matic and insert bolts with washers through the holes into the nuts. Tighten the bolts. 6. Reconnect the y-axis stepper and reassemble your makerbot.
