I’ve discovered a couple of loose screws during setup. Searching the posts reveals others have had similar experiences except mine is double the fun.
My screws seem to match this post
and this post
Neither of them were resolved, however I have discovered the likely spot for one of my screws, under the stepper for the X carriage. (see pics for info) However fitting the shorter screw in there reveals that either it’s the wrong screw (too short) or the hole was threaded as the screw no longer bites into the receiver. Examination of the hole shows tooling marks so I assume something was in there at some point, and the screw has threadlocker on it, which shows signs of wear, so it seems this screw was used for something at some point.
I’ve yet to find a likely home for the larger screw. Looking at the thread it’s likely its screwed into plastic.
At this point I’m not overly concerned and I’m keen to continue with my setup. I’m not concerned because
a) the stepper seems to have three other screws to keep things in place, and
b) none of the plastic housing appears to be critical to the functioning of the unit
If someone has ideas on where I can continue my search (esp someone who knows the design and knows where these screws are used) I’m happy to keep searching for a hole to match the longer screw with.
