I’ve been working on assembling my new XXL, and have noticed a couple of things -
(1) The Y-axis limit switch bracket holes for the (2) 35mm screws is drilled a little small. Even when the powder coating is cleaned out the holes have to be drilled up roughly one drill size to pass the shoulder on the screws.
(2) The X-axis limit switch contacts the belt clip instead of the plate - assuming I’ve assembled it correctly.
(3) The XXL manual contains some errors and ambiguities. It would also help a lot if it were published as a PDF rather than a web page. When printed as a web page the photos are scaled too small to be very useful.
(4) There are no technical drawings with explosions. I understand those are expensive, but the photos of the limit switches, for example aren’t as clear as a decent drawing would be.
At this point in the process, build quality and fit seem excellent for a product in this price range - with the minor exceptions noted above. It’s my opinion that the assembly docs need some work, however.
1 - unfortunately, this is a consequence of having a range of tolerances for this — if the hole is a bit small, and the powder coating a bit thick, one gets the result you observe — it’s been a while since it was complained of, so I think the contractor is doing better
I also mounted the X-axis limit switch on the other side of the plate – it was hitting the belt anchor, reducing the travel a bit. Used a button head cap screw to keep it from interfering with the drag chain. That was the other reason for the washers.
3 - we’re working on updating / correcting / improving the assembly instructions
4 - The assembly instructions used to be centered around technical drawings: Project Shapeoko with interactive SVGs such as:
