Hi Blockmodule, I’ve sent your case to our Support colleagues and they will contact you asap. Sorry about the belated response. Our support staff is overwhelmed by emails during this period and they are trying their best to respond .
I guess it’s because the problem you’ve come across is quite a rare one, so they have little experience with it and are trying to figure it out in cooperation with our R&D team. I totally understand your feelings and will ask about the progress from our Support.
This is described as information sharing for Snapmaker 2.0.
We received a reply that the white part inside the linear module (the plastic part of the inner diameter screw) is not sold only for both the old and new types of linear modules.
Therefore, even if the white plastic inner diameter screw wears out and the backlash becomes large, it cannot be repaired.
