Hi,
After assembly my K8400 i never got it to properly print anything, the steppers would miss some steps after just a few layers. After some investigation and help from this forum i was able to spot that a few of the rods was slightly bent, which could be one of the reasons for the problem. I asked Velleman for replacement and i got them today. During the time i waited i decided to take the printer apart and trying to rebuild it better aligned this time. Last time there was some gaps between the panels in the frame. But regardless of how much i try to get the panels aligned without gaps i fail to do so. When mounting the large corner pieces i manage to get a quite small gap somewhere around 0.2 mm at the top and bottom corners of the frame. The gap is slightly bigger in middle of each corner of the frame. After mounting the middle corner pieces the gap increases and the worst gap now is 0.9mm (see picture). Is gaps of this size a issue for the printer, or is it safe to continue with the build anyway? What about the 0.2 mm gap, is that OK?
Since i first assembled the kit with some gaps I’m afraid that the plastic parts have adjusted themselves after that, and therefore makes it even harden to assemble it correctly this time. Do you have any hints on how assemble the frame with minimal gap? I try to hold the panels at zero gap when tighten the bolts on the plastic parts, which helps to minimize the gap, but once tightning the bolt the gap also tends to increase, which makes it difficult.
