Step 6
Take the second T5 Belt and run around the 608 Bearings and the Y motor pulley, place the
ends under the belt clamps on the aluminum bed and tighten the M3 bolts just enough to hold
the belt still. now adjust the M8 Nuts either side of the 608 Bearings on the frame and move
until the belt, bearings and pulleys all run in a straight line, gradually tighten the M8 Nuts, the
Belt Clamps and the Y motor Mount while sliding the bed back and forward and ensure the
belt runs straight, the bed should move smoothly, however you may feel some resistance from
the stepper motors. Only a small amount of force should be needed to move the bed and it
should not have a jerky motion. Once you are happy gradually tighten the Nuts and tighten the
belt clamps down.
Step 7
Take a microswitch and attach it to an Endstop Holder using 20mm M2 Bolts with an M2
Washer on each side and an M2 Nut.
