Step 1: Route the belts

Feed each end of the x-axis belts down through the center channels in the two gantry columns. Then route the belts under the idler pulleys. Ensure there are no twists inside the extrusions. The belt teeth should be facing down towards the bed.

Step 2: Secure the belts

Secure both ends of each belt to a belt clip using a belt sleeve and the same method used when securing the y-axis belt. Then attach the belt clips to the raised bed using two wood screws. The belt clip tabs should be extending over the outside of the bed to serve as hardstops against the gantry wheel plates.

Just like tying your shoes

When tigtening and securing the belts and belt clips, use the same amount of force you would use to tie your shoes. There should be no slack in the system once the belt sleeve is in place.

Do not overtighten

Overtightening the belts may result in the front wheels of the gantry lifting off of the raised bed. If you notice this, loosen the belts slightly so that the gantry rests and rolls on the bed with all four wheels.

Step 3: Attach the x-axis cable carrier

Lay the loaded x-axis cable carrier onto the bed’s cable carrier support. Fasten it to the bed with two wood screws and to the cable carrier mount with two M5 x 16mm screws and M5 flange locknuts.
