Check for play on the slides

LARGE VOLUME series 3D Printer

LARGE VOLUME series

When the printer is in its Maintenance position you can check for play on the slides. Take the slide between your fingers like the picture and try carefully to shake/turn your hand:

If you feel any play in the slide, please adjust the concentric nut found on the single wheel side of the slide. Don’t overtighten this, you should still be able to turn the wheel with a finger without too much force applied:

PRO series

Maintaining correct tension on the belts is important to ensure good print quality. The belts transfer the movements of the motors to the slides. If the belts are too loose, print head movement may not be accurate, which can cause print inaccuracies. Over time, the belts may become slack.

It is recommended to check the tension of the belts at least once every three months. Pluck the three belts to check their tension. They should resonate, like a guitar string. Furthermore, the tension of the three belts should be equal. To restore the tension, perform the following steps:

  1. Home the printer (make sure the slides are all the way up)
  2. Loosen the set screws of the idler pulley with only 2 turns (don’t unscrew them completely)
  3. Push the idler unit firmly down with your thumb (don’t push on the pulley but push on thealuminium block/mount)
  4. Tighten the set screws of the idler pulley unit again to fix it.
  5. Repeat this for all three belts
  6. Make sure all belts are feeling the same in tension

 

DESK series

When the printer is still in its Maintenance position you can check for play on the slides.

Take the slide between two fingers like the picture and try carefully to shake/turn your hand.

If you feel any play in the slide, please adjust the concentric nut found on the single wheel side of the slide.

Don’t overtighten this, you should still be able to turn the wheel with a finger without too much force applied.
