The Vision Miner 22 IDEX 3D printer has four belts in total:
- Two belts for Y-axis movement (on the sides) control the central rail movement, on which both heads are placed.
- One belt for the X-axis controls the left head position.
- One belt for the U-axis controls the right head position.
Important: Power Off the machine before this manipulations and unplug the cord from the mains.
Tools: Hex 2mm driver & pliers
