Good idea.
If you read through the original announcement for the printer (and watch the linked video):
You’ll see that Peopoly makes a big deal about how they use “maglev” technology to eliminate belts and pulleys and the issues surround them.
When I watched the attached video, I was surprised to see that they use linear rails as I was expecting the “maglev” to replace both the force part of the equation along with the bearing (as in a maglev train).
Over the years, I’ve had a lot more problems with linear rails than belts and pulleys with poor quality on commercial printers and keeping them properly lubricated when I did shell out for HiWin rails.
