S5 belt coupling loose

Recommended Posts

The left belt coupling on the x axis is loose on the belt on my 2 week old S5. Twisting the x axis, i can get a half a tooth worth of movement as it slides along the belt. How do I go about tightening that up?  I dont want to just start tearing it apart. I have already had to do the axis alignment to fix slop in the x axis shaft that was there on delivery, and I imagine i will have to do that again once that block is fixed.

Thanks, but unfortunately it isn't a loose belt. The belt is tight, but the plastic coupling that wraps around the belt and supports the x axis rod slides back and forth on the belt. The rest of them grip tight and have 0 movement. It looks like they just unclip and pop off, but considering its only 2 weeks old, I don't want to break something and be down a printer when its just causing some rough prints now.

Ah, now I get it, so you say the belt slips in the "Sliding Block" (the name of that black thing)

 

Then it must have been wrongly installed in the factory, I never heard this before.

The block has two plastic parts that click together, I would ALWAYS advice to replace them after you take them apart, as the clips holding them together will almost certainly damage when opened.

There's a spring inside the block, that probably was mounted incorrectly.

 

It's an easy fix, but considering it's a new machine I would contact the re seller to have them do it,  Unless you're not close to a reseller then have them send you a new block+spring and do it yourself... I would not ship the machine away for something like this...

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
