Received my A250, but after assembling the platform, the 2 Linear modules attached to the base plate will gett stuck when moving the platform. Without the platform, they move freely, with the platform loosely attached also, but when tighten the screws, it wont move the full length.
when attaching the Y modules (the flat ones on the base) they have a ‘depression’ that they need to sit flat in, I would suggest removing them and giving them a good wiggle to ensure they have slotted in correctly?
Tried several times (and now again), they “fit” in the slots. I don’t think that one of the modules is not working, because when i remove the platform everything is moving correctly without any noise.
It sounds like the platform is wider than the difference between the two Z-axes.
