I’ve finally come to the point where I’m about to enter last part of assembly. X and Y rails are not square at all. I’ve tried all hints in tips from instructions, FAQ and forums - and the only thing left is to let it run for a while to “break in”. Unfortunately, it seems like the 25mm Biltema-conduits (from Norway) are not perfectly round at all. They vary from 29.9 to 25.3 mm. Let’s see what the breaking in does - and if nothing helps, then I would get rails from a steel retailer.
Well - my question for today: The roller mount does not fit perfectly upon the roller! It wobbles a little. I watched Toms build on this part, and it seemed like he had them fit tight. For me it seems like there will be a little air between, just like with the feet. I assumed it was no probem with a little air between the feet parts, like Tom has, but the roller mount seems more vulnerable? What do I do? Should I just go ahead, or would I risk breaking things??
Edit: The whole the mount and the roller makes is 24.2-3 mm. Does the PLA shrink??? I’m very certain that I have printed the F variant.
