What do the rollers look like? With all of the 3d printers out in the world, you would think that someone would have come up with an idea to fix some of these issues.
But the reason I asked what they. look like is that I had a device with rollers fail. The manufacturer was going to charge me a ransom for replacements. I found a set of ‘casters’ at the local Home Despot, and after taking the wheels out of them, they fit as replacements. I now have far more durable wheels with far better bearings. (The composition of the wheels is far more durable)
As for the rails, there are companies that make ‘u channel’ steel that might work to replace/cover the roughened surface of the rails on the MP1.
@_VLAD_The_Impailer; @Mat_Gordon; As I said, swapping the rails, putting the one currently on the right to the left and vice versa, directly changes the contact point where the roller runs. That is a simple mechanical fact. By doing that, the roller starts traveling on a fresh section of the rail surface instead of the worn groove it has been using. At a minimum, this should easily provide a several more thousand miles of smooth operation before any real replacement becomes necessary for the rails.
Now, the problem is not only the rails, it is also the rollers themselves. Looking at the picture, you can clearly see that the roller surface is extremely hard and already developing a sharp wear line. Instead of wearing down gradually, the roller material is rigid enough that it behaves almost like a metal wheel on a softer track. The result is that it concentrates all the pressure into a narrow contact point and literally digs a dent into the rail.
Well done, enjoy it! But honestly, that’s a design failure. During development, they should have seriously evaluated standard inline skate wheels (probably cheaper to source).
